Dear Fellow Stockholder:

On October 14, 2006, the board of directors of Open Solutions Inc., a Delaware corporation (the "Company"), acting in large part upon the unanimous recommendation of a special committee of the board of directors consisting of six independent and disinterested directors, unanimously approved a merger agreement providing for the merger of the Company with Harpoon Merger Corporation, a Delaware corporation and a wholly-owned subsidiary of Harpoon Acquisition Corporation. Harpoon Acquisition Corporation is a Delaware corporation whose current owners are investment funds affiliated with the private equity investment firms of The Carlyle Group and Providence Equity Partners Inc. If the merger is completed, you will be entitled to receive $38.00 in cash, without interest, for each share of the Company's common stock you own.

You will be asked, at a special meeting of the Company's stockholders, to vote to adopt the merger agreement. The board of directors has unanimously determined that it is fair to and in the best interests of the Company and its stockholders, and declared it advisable, to enter into the merger agreement and approved the execution, delivery and performance of the merger agreement and the consummation of the transactions contemplated thereby, including the merger. This determination is based, in large part, upon the unanimous recommendation of the special committee of the board of directors. The board of directors unanimously recommends that the Company's stockholders vote "FOR" the adoption of the merger agreement.

The date, time and place of the special meeting to consider and vote upon the merger agreement will be as follows:

[Date]
[Time]
[Place]

The proxy statement attached to this letter provides you with information about the proposed merger and the special meeting of the Company's stockholders and includes the merger agreement as Annex A. We encourage you to read the entire proxy statement carefully. You may also obtain more information about the Company from documents we have filed with the Securities and Exchange Commission.

Your vote is very important. The merger cannot be completed unless the merger agreement is adopted by the affirmative vote of the holders of a majority of the outstanding shares of Open Solutions Inc. common stock entitled to vote on it. If you fail to vote on the merger agreement, the effect will be the same as a vote against the adoption of the merger agreement.

Whether or not you plan to attend the meeting, please vote your shares by internet, telephone or mail. If you receive more than one proxy card because you own shares that are registered differently, please vote all of your shares shown on all of your proxy cards.

If you are a stockholder of record, voting by proxy will not prevent you from voting your shares in person if you subsequently choose to attend the special meeting.

If you have any questions or need assistance voting your shares, please contact our Investor Relations Department at (860) 652-3155 or our proxy solicitation agent, The Altman Group, toll-free at (800) 330-4627 (bank and broker firms call collect at (800) 330-4627). If your broker, bank or other nominee holds your shares, you should also call your broker, bank or other nominee for additional information.

Our board of directors and management thank you for your cooperation and continued support.

Very truly yours,

Douglas K. Anderson		Louis Hernandez, Jr.
Chairman of the Special Committee		Chairman of the Board and Chief Executive Officer

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
TO BE HELD

To Our Stockholders:

A special meeting of stockholders of Open Solutions Inc., a Delaware corporation ("Open Solutions" or the "Company"), will be held on , Eastern Time, at , , , for the following purposes:

1.: To consider and vote on a proposal to adopt the Agreement and Plan of Merger, dated as of October 14, 2006 (as it may be amended from time to time, the "merger agreement"), among the Company, Harpoon Acquisition Corporation and Harpoon Merger Corporation;
2.: To approve the adjournment of the meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the meeting to adopt the merger agreement; and
3.: To act upon other business as may properly come before the meeting or any postponement or adjournment thereof.

Your board of directors has unanimously approved and recommends that you vote "FOR" the adoption of the merger agreement and "FOR" the adjournment proposal, which are discussed in more detail in the attached proxy statement.

Only holders of record of Open Solutions' common stock at the close of business on are entitled to notice of the special meeting and to vote at the meeting or at any postponement or adjournment thereof. All stockholders of record are cordially invited to attend the special meeting in person. A list of our stockholders will be available at our principal executive offices at 455 Winding Brook Drive, Glastonbury, Connecticut, during ordinary business hours for ten days prior to the special meeting.

Your vote is important, regardless of the number of shares of the Company's common stock you own. The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Open Solutions' common stock entitled to vote thereon. The proposal to adjourn the meeting, if necessary or appropriate, to solicit additional proxies requires the affirmative vote of a majority of the shares of Open Solutions' common stock cast by the holders of all of the shares of common stock present or represented by proxy at the special meeting. Even if you plan to attend the special meeting in person, we request that you complete, sign, date and return the enclosed proxy card and thus ensure that your shares will be represented at the special meeting if you are unable to attend.

You also may vote your shares by proxy using a toll-free telephone number or the internet. We have provided instructions on the proxy card for using these services. If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted in favor of the adoption of the merger agreement and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. If you fail to return your proxy card, the effect will be that your shares will

not be counted for purposes of determining whether a quorum is present at the special meeting and will have the same effect as a vote against the adoption of the merger agreement, but will not affect the outcome of the vote regarding the adjournment of the meeting, if necessary or appropriate, to solicit additional proxies. If you are a stockholder of record and do attend the special meeting and wish to vote in person, you may withdraw your proxy and vote in person.

Open Solutions stockholders who do not vote in favor of the adoption of the merger agreement will have the right to seek appraisal of the fair value of their shares if the merger is completed, but only if they deliver a written demand for appraisal to Open Solutions before the vote is taken on the merger agreement and they comply with the other requirements of Delaware law, which are summarized in the accompanying proxy statement.

Harpoon Merger Corporation, a Delaware corporation and direct wholly-owned subsidiary of Parent, which we refer to in this proxy statement from time to time as Merger Co, was formed on

October 12, 2006, solely for the purpose of effecting the merger. Merger Co has not engaged in any business except in furtherance of this purpose.

Each of Parent and Merger Co is currently owned by investment funds affiliated with the private equity investment firms of The Carlyle Group, which we refer to from time to time in this proxy statement as Carlyle, and Providence Equity Partners Inc., which we refer to from time to time in this proxy statement as Providence. We collectively refer to Carlyle and Providence from time to time in this proxy statement as the Sponsors.

The Proposal (Page 15)

You will be asked to consider and vote upon adoption of the Agreement and Plan of Merger, dated as of October 14, 2006, or the merger agreement, among the Company, Parent and Merger Co. The merger agreement provides that Merger Co will be merged with and into the Company, and each outstanding share of the Company's common stock (other than shares held in the treasury of the Company or owned by Parent, Merger Co or any direct or indirect wholly-owned subsidiary of Parent, Merger Co or the Company and other than shares held by stockholders who are entitled to and properly exercise and do not timely withdraw demand for statutory appraisal rights in connection with such shares in compliance with all of the required procedures under Delaware law) will be cancelled and converted at the effective time of the merger into the right to receive $38.00 in cash, without interest and less any required withholding taxes.

The persons named in the accompanying proxy card will also have discretionary authority to vote upon other business, if any, that properly comes before the special meeting and any adjournments or postponements of the special meeting.

The Special Meeting (Page 15)

The special meeting will be held on , starting at , Eastern Time, at , , .

Record Date (Page 15)

You are entitled to vote at the special meeting if you owned shares of the Company's common stock at the close of business on , the record date for the special meeting. You will have one vote for each share of the Company's common stock that you owned on the record date. As of the record date, there were shares of the Company's common stock entitled to be voted.

Required Vote (Page 15)

For us to complete the merger, stockholders holding a majority of our shares of common stock outstanding at the close of business on the record date must vote "FOR" the adoption of the merger agreement. A failure to vote your shares of the Company's common stock or an abstention will have the same effect as a vote against the merger.

As of the record date, the directors and current executive officers of Open Solutions beneficially owned in the aggregate (excluding options, unvested restricted stock and restricted stock units) approximately % of the shares of the Company's common stock entitled to vote at the special meeting. Each of the directors and current executive officers has advised us that he or she currently plans to vote all of his or her shares in favor of the adoption of the merger agreement.

Any Open Solutions stockholder of record entitled to vote may submit a proxy by telephone, the Internet or returning the enclosed proxy card by mail, or may vote in person by appearing at the special meeting. If your shares are held in "street name" by your broker, you should instruct your

broker on how to vote your shares using the instructions provided by your broker. If you do not provide your broker with instructions, your shares will not be voted and that will have the same effect as a vote against the merger.

Any Open Solutions stockholder of record who executes and returns a proxy card (or submits a proxy via telephone or the Internet) may revoke the proxy at any time before it is voted in any one of the following ways:

•: filing with the Company's Corporate Secretary, at or before the special meeting, a written notice of revocation that is dated a later date than the proxy;
•: sending a later-dated proxy relating to the same shares to the Company's Corporate Secretary, at or before the special meeting;
•: submitting a later-dated proxy by the Internet or by telephone, at or before the special meeting; or
•: attending the special meeting and voting in person by ballot.

Simply attending the special meeting will not constitute revocation of a proxy. If you have instructed your broker to vote your shares, the above-described options for revoking your proxy do not apply and instead you must follow the directions provided by your broker to change these instructions.

When the Merger Will be Completed (Page 59)

We are working to complete the merger as soon as possible. We anticipate completing the merger in the first quarter of 2007, subject to adoption of the merger agreement by the Company's stockholders and the satisfaction of the other closing conditions. In addition, Parent and Merger Co are not obligated to complete the merger until five calendar days after the expiration of a 20 consecutive business day "marketing period" throughout which (i) Parent and Merger Co have the financial information that the Company is required to provide pursuant to the merger agreement to complete the debt financing of the merger, (ii) the Company has filed such reports under the securities laws that it is required to file pursuant to the merger agreement to complete the debt financing of the merger, (iii) certain conditions to the closing of the merger, as set forth in the merger agreement, have been satisfied (or shall be capable at such time of being satisfied), and (iv) our accountants, PricewaterhouseCoopers LLP, have not withdrawn their audit opinion with respect to any financial statements contained in our recent filings with the SEC; provided that if the marketing period would not end on or prior to December 15, 2006, the marketing period will not commence earlier than January 2, 2007.

Effects of the Merger (Pages 39-40)

If the merger agreement is adopted by the Company's stockholders and the other conditions to closing are satisfied, Merger Co will be merged with and into the Company, with the Company being the surviving corporation in the merger. Upon completion of the merger, the Company's common stock will be converted into the right to receive $38.00 per share, without interest and less any required withholding taxes. Following the completion of the merger, our stock will no longer be publicly traded and you will cease to have any ownership interest in the Company and will not participate in any future earnings and growth of the Company.

Recommendation of the Company's Board of Directors (Page 28)

Our board of directors formed a special committee on September 8, 2006 to take any and all actions necessary or advisable in connection with the receipt, evaluation, negotiation, response, rejection, and, if appropriate and to the extent permitted by law, the agreement, or recommendation to

or of the board regarding the agreement, of a possible sale of the Company. The special committee unanimously resolved to recommend that the board of directors approve the merger agreement, the merger and the transactions contemplated thereby and that the board of directors resolve to recommend to the Company's stockholders that they vote to adopt the merger agreement.

Our board of directors, acting in large part upon the unanimous recommendation of the special committee, has unanimously determined that the merger agreement is advisable, fair to and in the best interests of the Company and its stockholders, approved the merger agreement, and recommended that Open Solutions' stockholders vote "FOR" the adoption of the merger agreement.

For the factors considered by our board of directors in reaching its decision to approve and adopt the merger agreement and the merger, see "The Transaction—Reasons for the Merger; Recommendation of the Special Committee and of Our Board of Directors." See also "The Transaction—Interests of the Company's Directors and Executive Officers in the Merger."

Opinion of SunTrust Robinson Humphrey (Page 32 and Annex B)

In connection with the proposed merger, SunTrust Robinson Humphrey, the special committee's financial advisor, delivered its oral opinion to the special committee, which was subsequently confirmed in writing, that, as of October 14, 2006, and based upon and subject to the various qualifications, limitations, factors and assumptions set forth therein, the $38.00 in cash per share of our common stock to be received by the holders of shares of our common stock pursuant to the merger agreement is fair to such holders from a financial point of view.

The full text of the written opinion of SunTrust Robinson Humphrey, dated October 14, 2006, which sets forth, among other things, assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex B to this proxy statement. The opinion was provided to the special committee solely in connection with and for the purposes of its consideration of the transactions contemplated by the merger agreement. The SunTrust Robinson Humphrey opinion does not constitute a recommendation as to how any holder of shares of our common stock or any other person should vote or act with respect to the transactions contemplated by the merger agreement or any other matter.

Financing (Page 40)

The Company and the Sponsors estimate that the total amount of funds necessary to consummate the merger and related transactions (including payment of the aggregate merger consideration, the repayment or refinancing of some of the Company's currently outstanding debt and related fees and expenses) will be approximately $1.4 billion. The amount is expected to be provided through a combination of (a) up to $530.0 million under senior secured credit facilities, (b) bridge loan facilities and senior subordinated notes with an aggregate principal amount of up to $325.0 million, and (c) aggregate equity commitments of $560.0 million from the Sponsors.

Parent has agreed to use its reasonable best efforts to arrange the debt financing on the terms and conditions described in the commitment letters related to the aforementioned financing. Those facilities and notes are conditioned on certain conditions described in further detail under "The Merger—Financing—Debt Financing" beginning on page 42.

The closing of the merger is not conditioned on the receipt of the debt financing by Parent and Merger Co. Parent, however, is not required to consummate the merger until after the completion of the marketing period (plus five calendar days) as described above under "When the Merger Will be Completed" and in further detail under "The Merger Agreement—Marketing Period" beginning on page 59.

Treatment of Stock Options (Page 44)

The merger agreement provides that, except as otherwise agreed between Parent and a holder, holders of the Company's outstanding stock options will receive, in exchange for the cancellation of their stock options, cash equal to the excess of $38.00 over the applicable per share exercise price for each stock option (whether vested or unvested) held, less applicable withholding tax.

Treatment of Restricted Stock and Restricted Stock Units (Page 45)

The merger agreement provides that, except as otherwise agreed between Parent and a holder,

•: each outstanding share of our restricted stock will become fully vested and will be converted into the right to receive $38.00 in cash; and
•: each of our outstanding restricted stock units will become fully vested and will be canceled, and the holder of the restricted stock unit will be entitled to receive in cash $38.00 (together with the value of any deemed dividend equivalents accrued but unpaid with respect to the restricted stock units) for each underlying unit,

in each case, less any amounts required to be withheld under any applicable law.

Treatment of Contributions to the Company's Employee Stock Purchase Plan (Page 60)

No new offering periods under the Company's Employee Stock Purchase Plan will be commenced following the execution date of the merger agreement. Shares held by participants following the final exercise under the Employee Stock Purchase Plan, at the conclusion of the offering period in effect at the time of the execution of the merger agreement, will be treated in the same manner as other outstanding shares of our common stock in the merger.

Interests of the Company's Directors and Executive Officers in the Merger (Page 44)

In considering the recommendation of the board of directors, you should be aware that our directors and executive officers may have interests in the merger and/or prospective relationships with the Sponsors that are different from, or in addition to, your interests as a stockholder, including the following:

•: our directors and executive officers will have their vested and unvested stock options, restricted stock and restricted stock units canceled and cashed out in connection with the merger;
•: our current executive officers are covered by change of control termination protection arrangements that provide certain severance payments and benefits in the case of the executive officer's termination of employment under certain circumstances following a change in control;
•: the merger agreement provides for indemnification arrangements for each of our current and former directors and officers that will continue for six years following the effective time of the merger as well as insurance coverage covering his or her service to the Company as a director or officer;
•: the Company currently anticipates paying transaction bonuses of up to $1 million, in the aggregate, to certain executive officers and other members of senior management of the Company in connection with the merger;
•: although no agreements have been entered into as of the date of this proxy statement, the Sponsors have informed us that it is their intention to retain members of our existing management team with the surviving corporation after the merger is completed, and in that connection, members of management currently are engaged in discussions with representatives of

Parent and we believe that these persons are likely to enter into new arrangements with Parent, Merger Co or their affiliates regarding employment with the surviving corporation;

•: Parent has offered Mr. Hernandez and certain of our executive officers who hold outstanding stock options, restricted stock and/or restricted stock units immediately prior to the completion of the merger the opportunity to exchange, simultaneously with the consummation of the merger, some or all of such outstanding stock options, restricted stock and/or restricted stock units (in lieu of the cash out and cancellation described above) for options to purchase shares of Parent common stock or shares of Parent common stock, as the case may be. This offer is subject to further negotiation and discussion between Parent and the offerees, and no terms or conditions with respect to such offer have been finalized as of the date of this proxy statement; and
•: although no agreements have been entered into as of the date of this proxy statement, it is expected that certain of our officers and key employees will be granted options to purchase shares of Parent common stock following the consummation of the merger.

Material United States Federal Income Tax Consequences (Page 48)

If you are a U.S. holder (as defined below) of our common stock, the merger will be a taxable transaction to you. For U.S. federal income tax purposes, your receipt of cash in exchange for your shares of the Company's common stock generally will cause you to recognize a gain or loss measured by the difference, if any, between the cash you receive in the merger and your adjusted tax basis in your shares. If you are a non-U.S. holder (as defined below) of our common stock, the merger will generally not be a taxable transaction to you under U.S. federal income tax laws unless you have certain connections to the United States. You should consult your own tax advisor for a full understanding of the U.S. federal income tax consequences of the merger.

Regulatory Approvals (Page 51)

The merger is subject to review under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or the Hart-Scott-Rodino Act. The Company also derives revenues in certain other jurisdictions, in particular Canada, where regulatory filings or approvals may be required or advisable in connection with the completion of the merger. We are currently in the process of reviewing where regulatory filings or approvals may be required or desirable, and we will make filings in such jurisdictions. The parties filed their respective notification and report forms with the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice under the Hart-Scott-Rodino Act on October 30, 2006 and were granted early termination of the Hart-Scott-Rodino Act waiting period on November 14, 2006.

Conditions to the Merger (Page 64)

The consummation of the merger depends on the satisfaction or waiver of a number of conditions, including the following:

•: the merger agreement must have been adopted by the affirmative vote of the holders of a majority of the outstanding shares of the Company's common stock entitled to vote thereon;
•: the waiting period under the Hart-Scott-Rodino Act Antitrust Improvements Act of 1976, as amended, and any other material antitrust laws, must have expired;
•: no laws, injunctions or orders that prohibit, restrain or enjoin consummation of the transactions shall be in effect;

•: the Company's and Parent's and Merger Co's representations and warranties must be true and correct as of the closing date in a manner described under the caption, "The Merger Agreement—Conditions to the Merger";
•: the Company and Parent and Merger Co must have performed and complied in all material respects with all covenants and obligations that each is required to perform under the merger agreement; and
•: there shall not have occurred since the date of execution of the merger agreement any event, circumstance, development, change or effect that has had, or would reasonably be expected to have, a "Company material adverse effect" (as described in further detail in "The Merger Agreement—Representations and Warranties").

Solicitation (Page 61)

Pursuant to the merger agreement, prior to 11:59 p.m. (EST), on November 8, 2006 (the "go-shop period"), the Company was permitted to, directly or indirectly (i) initiate, solicit and encourage acquisition proposals from third parties to acquire all or part of the Company or its assets or revenues and (ii) enter into and maintain discussions or negotiations with respect to such acquisition proposals, or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations, in each case in accordance with the terms of the merger agreement.

Prior to obtaining stockholder approval, if the board of directors (acting through or based on the advice of the special committee) determines in good faith (after consultation with its legal advisors) that the failure to do so would be inconsistent with its fiduciary duties under applicable law, the Company may terminate the merger agreement to enter into an agreement with respect to an acquisition proposal that constitutes a superior proposal if the Company complies with the terms of the merger agreement described under "The Merger Agreement—Recommendation Withdrawal/ Termination in Connection with a Superior Proposal," including negotiating with Parent in good faith to make adjustments to the merger agreement so that such acquisition proposal ceases to constitute a superior proposal and paying a termination fee.

From and after the expiration of the go-shop period, the Company is generally not permitted to, among other things, (i) initiate, solicit or knowingly encourage (including by way of providing information) the submission of any inquiries, proposals or offers, or engage in any discussions or negotiations that may lead to an acquisition proposal or (ii) approve or recommend, or publicly propose to approve or recommend, an acquisition proposal or enter into any agreement providing for or relating to an acquisition proposal.

Notwithstanding these restrictions, after the expiration of the go-shop period and prior to obtaining stockholder approval, the Company may, under certain circumstances described under "The Merger Agreement—Restrictions on Solicitation of Other Offers", respond to a bona fide written acquisition proposal if the Company complies with certain terms of the merger agreement described under "The Merger Agreement—Recommendation Withdrawal/ Termination in Connection with a Superior Proposal."

Termination of the Merger Agreement (Page 65)

The merger agreement may be terminated:

•: by mutual written consent of the Company and Parent;

•

by either the Company or Parent, if:

•: the merger is not consummated on or before March 31, 2007, unless such failure is the result of, or caused by, the terminating party's failure to observe any obligation under the merger agreement;
•: there is any final and nonappealable injunction, order, decree or ruling that makes consummation of the merger illegal or otherwise prevents or prohibits the consummation of the merger; or
•: the Company's stockholders, at the special meeting or at any adjournment thereof, fail to adopt the merger agreement;

•

by Parent if:

•: the Company has breached any of its representations, warranties, covenants or agreements under the merger agreement which would give rise to the failure of certain conditions to closing and where that breach has not been, or cannot be, cured on or before March 31, 2007 (provided that Parent is not then in material breach of the merger agreement so as to cause certain conditions to closing not be satisfied); or
•: the board of directors of the Company or the special committee (i) effects a recommendation withdrawal (as defined below in "The Merger Agreement—Recommendation Withdrawal/ Termination in Connection with a Superior Proposal"); (ii) approves or recommends to the stockholders of the Company an acquisition proposal other than the merger contemplated by the merger agreement, or resolves to effect the foregoing; or (iii) fails to include a recommendation that the stockholders adopt the merger agreement in our proxy statement in connection with the merger;

•

by the Company if:

•: Parent or Merger Co has breached any of its representations, warranties, covenants or agreements under the merger agreement which would give rise to the failure of certain conditions to closing and where that breach has not been, or cannot be, cured on or before March 31, 2007 (provided that the Company is not then in material breach of the merger agreement so as to cause certain conditions to closing not to be satisfied);
•: prior to obtaining stockholder approval, we terminate the merger agreement in order to enter into an agreement with respect to a superior proposal, provided that the Company complies with the terms described below in "The Merger Agreement—Recommendation Withdrawal/Termination in Connection with a Superior Proposal," including that the Company pays to Parent concurrently with termination the termination fee described below; or
•: if all conditions to the obligations of Parent and Merger Co (other than delivery of an officer's certificate) have been satisfied and Parent fails to consummate the merger no later than five calendar days after the final day of the marketing period.

Termination Fee (Page 66)

Under certain circumstances, in connection with the termination of the merger agreement, we will be required to pay a termination fee of $30 million as directed by Parent. If the Company had terminated the merger agreement in order to enter into a definitive agreement with respect to an acquisition proposal other than the merger contemplated by the merger agreement on or prior to 11:59 p.m. (EST) on November 8, 2006, such termination fee would have been $12 million.

In the event the merger agreement is terminated because the Company's stockholders fail to adopt the merger agreement at the special meeting or any adjournment thereof or because we materially breach our representations, warranties, covenants or agreements in the merger agreement such that certain closing conditions would not be satisfied and such breach is not cured on or before March 31, 2007, then we are required to reimburse Parent for expenses incurred in connection with the merger agreement, up to a maximum of $5 million, which amount will be offset against the termination fee described above, if payable.

In the event that we terminate the merger agreement because Parent (i) breaches its representations, warranties, covenants or agreements in the merger agreement such that certain closing conditions would not be satisfied and such breach is not cured on or before March 31, 2007 (provided that we are not then in material breach of the agreement so as to cause certain conditions to closing not to be satisfied) or (ii) fails to complete the merger no later than five days after the final day of the marketing period and certain conditions to the obligations of Parent and Merger Co to consummate the merger have otherwise been satisfied, then Parent will be required to pay the Company a $30 million termination fee. This termination fee payable to the Company is the exclusive remedy of the Company. The aggregate liability of Parent and its affiliates arising from any breach of the merger agreement or any losses or damages incurred by the Company or its affiliates in connection therewith is in any event capped at $30 million. Each of the Sponsors has agreed severally to guarantee the obligation of Parent to pay this termination fee subject to a cap equal to such Sponsor's pro-rata share of $30 million, which share is proportionate to its equity commitment in Parent as compared to the equity commitments of the other Sponsor.

Appraisal Rights (Page 71 and Annex C)

Delaware law provides you with appraisal rights in the merger. This means that, if you fully comply with the procedures for perfecting appraisal rights provided for under Delaware law, you are entitled to have the fair value of your shares determined by the Delaware Court of Chancery and to receive payment in cash for your shares based on that valuation in lieu of the merger consideration. The ultimate amount you receive in an appraisal proceeding may be more or less than, or the same as, the amount you would have received under the merger agreement. To exercise your appraisal rights, you must deliver a written demand for appraisal to the Company before the vote on the merger agreement is taken at the special meeting and you must not vote in favor of the adoption of the merger agreement. Your failure to follow exactly the procedures specified under Delaware law will result in the loss of your appraisal rights. A copy of Section 262 of the General Corporation Law of the State of Delaware, or DGCL, is attached to this proxy statement as Annex C.

A:: For us to complete the merger, stockholders holding a majority of our common stock outstanding at the close of business on the record date must vote "FOR" the adoption of the merger agreement. Accordingly, the failure to vote or an abstention will have the same effect on this vote as a vote against adoption of the merger agreement.

Q:

What do I need to do now?

A:

We urge you to read this proxy statement carefully, including its annexes and the documents referred to or incorporated by reference in this proxy statement, and to consider how the merger affects you. You can ensure that your shares are voted at the special meeting by submitting your proxy via:

•: telephone, using the toll-free number listed on each proxy card (if you are a registered stockholder, that is if you hold your stock in your name) or voting instruction card (if your shares are held in "street name," meaning that your shares are held in the name of a broker, bank or other nominee and your broker, bank, or other nominee makes telephone voting available);
•: the Internet, at the address provided on each proxy card (if you are a registered stockholder) or voting instruction card (if your shares are held in "street name" and your broker, bank, or other nominee makes Internet voting available); or
•: mail, by completing, signing, dating and mailing each proxy card or voting instruction card and returning it in the envelope provided.

Q:

If my shares are held in "street name" by my broker, bank or other nominee will my broker, bank or other nominee vote my shares for me?

A:

Yes. However, your broker, bank or nominee will only vote if you provide instructions on how to vote. You should follow the directions provided by your broker, bank or other nominee regarding how to instruct your broker, bank or other nominee to vote your shares. Without those instructions, your shares will not be voted, which will have the same effect as voting against the merger.

Q:

Should I send in my stock certificates or other evidence of ownership now?

A:

No. After the merger is completed, you will be sent a letter of transmittal with detailed written instructions for exchanging your stock certifications for the merger consideration. If your shares of common stock are held in "street name" by your broker, bank or other nominee you will receive instructions from your broker, bank or other nominee as to how to effect the surrender of your "street name" shares in exchange for the merger consideration. Please do not send your certificates with your proxy.

Q:: Can I change my vote?
A:: Yes. You can change your vote at any time before your proxy is voted at the special meeting. If you are a registered stockholder, you may revoke your proxy by notifying the Company's Corporate Secretary in writing at Open Solutions Inc., 455 Winding Brook Drive, Glastonbury, Connecticut 06033, Attn: Corporate Secretary, or by submitting a new proxy by telephone, the Internet or mail, in each case, dated after the date of the proxy being revoked. In addition, your proxy may be revoked by attending the special meeting and voting in person (you must vote in person, simply attending the special meeting will not cause your proxy to be revoked).
: Please note that if you hold your shares of common stock in "street name" and you have instructed a broker, bank or other nominee to vote your shares, the above-described options for changing your vote do not apply, and instead you must follow the instructions received from your broker, bank or other nominee to change your vote.
Q:: What does it mean if I get more than one proxy card or voting instruction card?
A:: If your shares are registered differently or are held in more than one account, you will receive more than one proxy or voting instruction card. Please complete and return all of the proxy cards or voting instruction cards you receive (or submit each of your proxies by telephone or the Internet, if available to you) to ensure that all of your shares are voted.
Q:: Who will count the votes?
A:: A representative of our transfer agent, Computershare Trust Company, N.A., will count the votes.
Q:: What effects will the proposed merger have on Open Solutions?
A:: As a result of the proposed merger, Open Solutions will cease to be a publicly-traded company and will be wholly-owned by Parent, an entity currently owned by investment funds affiliated with the Sponsors. Following consummation of the merger, the registration of our common stock and our reporting obligations with respect to our common stock under the Securities Exchange Act of 1934, as amended, or the Exchange Act, will be terminated upon application to the Securities and Exchange Commission, or SEC. In addition, upon completion of the proposed merger, shares of our common stock will no longer be listed on any stock exchange or quotation system, including the NASDAQ National Market.
Q:: What happens if the merger is not consummated?
A.: If the merger agreement is not adopted by Open Solutions' stockholders or if the merger is not completed for any other reason, stockholders will not receive any payment for their shares in connection with the merger. Instead, Open Solutions will remain an independent public company and Open Solutions common stock will continue to be listed and traded on the NASDAQ National Market. See the section captioned "The Transaction—Delisting and Deregistration of Open Solutions Common Stock; Failure to Consummate the Merger." Under specified circumstances, Open Solutions may be required to pay Parent a termination fee or reimburse Parent for its out-of-pocket expenses as described under the caption "The Merger Agreement—Termination Fees; Expense Reimbursement."

THE SPECIAL MEETING

Time, Place and Purpose of the Special Meeting

This proxy statement is being furnished to our stockholders as part of the solicitation of proxies by our board of directors for use at the special meeting to be held on , starting at , Eastern Time, at , , or at any adjournment or postponement thereof. The purpose of the special meeting is for our stockholders to consider and vote upon the adoption of the merger agreement. Our stockholders must adopt the merger agreement and the required vote described below must be obtained for the merger to occur. If our stockholders fail to adopt the merger agreement, the merger will not occur. A copy of the merger agreement is attached to this proxy statement as Annex A. This proxy statement and the enclosed form of proxy are first being mailed to our stockholders on or about .

Record Date and Quorum

The holders of record of the Company's common stock as of the close of business on , the record date for the special meeting, are entitled to receive notice of and to vote at, the special meeting. On the record date, shares of the Company's common stock were outstanding.

The holders of a majority of the outstanding shares of the Company's common stock on the record date represented in person or by proxy will constitute a quorum for purposes of the special meeting. A quorum is necessary to hold the special meeting. Any shares of the Company's common stock held in treasury by the Company or by any of our subsidiaries are not considered to be outstanding for purposes of determining a quorum. Once a share is represented at the special meeting, it will be counted for the purpose of determining a quorum at the special meeting and any adjournment of the special meeting. However, if a new record date is set for the adjourned special meeting, then a new quorum will have to be established.

Required Vote

Completion of the merger requires the adoption of the merger agreement by the affirmative vote of the holders of a majority of the Company's common stock outstanding on the record date and entitled to vote thereon. Each holder of record of shares of common stock entitled to vote will have the right to one vote for each such share of common stock held.

As of , the record date, the directors and current executive officers of the Company beneficially owned (excluding options, restricted stock and restricted stock units), in the aggregate, shares of the Company's common stock, or approximately % of the outstanding shares of the Company's common stock. The directors and current executive officers have informed the Company that they currently intend to vote all of their shares of the Company's common stock "FOR" the adoption of the merger agreement and "FOR" any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies.

Proxies; Revocation

If you are a stockholder of record and submit a proxy by telephone or the Internet or by returning a signed proxy card by mail, your shares will be voted at the special meeting as you indicate on your proxy card or by such other method. If you sign your proxy card but no voting instructions are indicated, your shares of the Company's common stock will be voted "FOR" the adoption of the merger agreement and "FOR" any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies.

If your shares are held in "street name" by your broker, bank or other nominee, you should instruct your broker, bank or other nominee how to vote your shares using the instructions provided by

your broker, bank or other nominee. If you have not received such voting instructions or require further information regarding such voting instructions, contact your broker, bank or other nominee for directions on how to vote your shares. Under applicable rules, brokers who hold shares in "street name" for customers may not exercise their voting discretion with respect to the approval of non-routine matters such as the merger proposal and thus, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote such shares with respect to the adoption of the merger agreement (i.e., "broker non-votes"). Shares of Company common stock held by persons attending the special meeting but not voting, or shares for which the Company has received proxies with respect to which holders have abstained from voting, will be considered abstentions. Abstentions and properly executed broker non-votes, if any, will be treated as shares that are present and entitled to vote at the special meeting for purposes of determining whether a quorum exists but will have the same effect as a vote "AGAINST" adoption of the merger agreement.

You may revoke your proxy at any time before the vote is taken at the special meeting. To revoke your proxy, you must advise our Corporate Secretary in writing, at Open Solutions Inc., 455 Winding Brook Drive, Glastonbury, Connecticut 06033, Attn: Corporate Secretary, submit a proxy by telephone, the Internet or mail dated after the date of the proxy you wish to revoke or attend the special meeting and vote your shares in person. Attendance at the special meeting will not by itself constitute revocation of a proxy.

Please note that if you have instructed your broker, bank or other nominee to vote your shares, the options for revoking your proxy described in the paragraph above do not apply and instead you must follow the directions provided by your broker, bank or other nominee to change these instructions.

Open Solutions does not expect that any matter other than the adoption of the merger agreement (and the approval of the adjournment of the meeting, if necessary or appropriate, to solicit additional proxies) will be brought before the special meeting. If, however, any such other matter is properly presented at the special meeting or any adjournment or postponement of the special meeting, the persons appointed as proxies will have discretionary authority to vote the shares represented by duly executed proxies in accordance with their discretion and judgment.

Submitting Proxies Via the Internet or by Telephone

Stockholders of record and many stockholders who hold their shares through a broker, bank or other nominee will have the option to submit their proxies or voting instructions via the Internet or by telephone. There are separate arrangements for using the Internet and telephone to submit your proxy depending on whether you are a stockholder of record or your shares are held in "street name" by your broker, bank or other nominee. If your shares are held in "street name," you should check the voting instruction card provided by your broker, bank or other nominee to see which options are available and the procedures to be followed.

In addition to submitting the enclosed proxy card by mail, Open Solutions stockholders of record may submit their proxies:

•: via the Internet by visiting a website established for that purpose at and following the instructions on the website; or
•: by calling the toll-free number in the United States, Puerto Rico or Canada on a touch-tone phone and following the recorded instructions.

Adjournments

Although it is not currently expected, the special meeting may be adjourned for the purpose of soliciting additional proxies. Any adjournment may be made without notice (if the adjournment is not

for more than thirty days) by an announcement made at the special meeting of the time, date and place of the adjourned meeting. In the event that there is present, in person or by proxy, sufficient favorable voting power to secure the vote of the stockholders of the Company necessary to adopt the merger agreement, the Company does not anticipate that we will adjourn or postpone the meeting unless the Company is advised by counsel that failure to do so could reasonably be expected to result in a violation of U.S. federal securities laws. Any signed proxies received by the Company in which no voting instructions are provided on such matter will be voted in favor of an adjournment in these circumstances. Any adjournment or postponement of the special meeting for the purpose of soliciting additional proxies will allow the Company's stockholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned or postponed.

Solicitation of Proxies

The Company will pay the cost of this proxy solicitation. In addition to soliciting proxies by mail, directors, officers and employees of the Company may solicit proxies personally and by telephone, facsimile or other electronic means of communication. These persons will not receive additional or special compensation for such solicitation services. The Company will, upon request, reimburse brokers, banks and other nominees for their expenses in sending proxy materials to their customers who are beneficial owners and obtaining their voting instructions. The Company has retained The Altman Group, a proxy solicitation firm, to assist it in the solicitation of proxies for the special meeting and will pay The Altman Group a base fee of $6,000, plus reimbursement of out-of-pocket expenses.

THE TRANSACTION

Background of the Merger

The Company regularly reviews and evaluates its business strategy and strategic alternatives and prospects for continued operations and growth. In connection with these processes, management and the board of directors of the Company have on certain occasions solicited advice from financial advisors, including Wachovia Capital Markets, LLC, which we refer to in this proxy statement as Wachovia. Wachovia has advised the Company in connection with certain prior transactions, including the debt financing for the Company's acquisition of the Information Services Group of The BISYS Group Inc. in early 2006 and the Company's offerings of its common stock and convertible notes in 2004 and 2005, respectively.

From time to time during 2005 and 2006, representatives of private equity firms, including Carlyle and Providence, expressed interest to senior management of the Company about partnering with the Company to pursue strategic transactions or taking the Company private. These contacts did not result in substantive discussions.

In early 2006, at the request of senior management of the Company, Wachovia reviewed with management various strategic alternatives available to the Company, including potential smaller and larger-scale strategic acquisition opportunities. In addition, Wachovia discussed with management additional financial alternatives available to the Company, including public offerings of equity and/or debt securities, recapitalizations, and general discussions about a possible leveraged buyout transaction. Throughout this period, members of senior management had informal discussions with our board of directors regarding the attractiveness and feasibility of the potential strategic acquisitions as part of the Company's ongoing effort to obtain what management believed to be appropriate credit in the market for the Company's positive growth rate and cash flow performance, and to otherwise maximize stockholder value. During the course of these discussions, management and the board concluded that in light of the Company's operating and financial performance, the Company would continue to pursue its current course of growth, primarily through small to medium-size strategic acquisitions, to the extent such opportunities became available to the Company.

In April 2006, senior management of the Company continued to discuss with our board of directors its business strategy and strategic alternatives, including alternatives to increase stockholder value through additional financial alternatives available to the Company such as public offerings of equity and/or debt securities, recapitalizations, and a possible leveraged buyout transaction. Following these discussions, the Company's board of directors authorized senior management to explore further the feasibility and attractiveness of such financing alternatives, as well as to ascertain the interest of certain third parties with respect to a possible leveraged buyout transaction involving the Company. However, due to management's and the board's concerns regarding divulging confidential information to competitors and the adverse impact of potential leaks with respect to the Company's activities on the Company's relationships with customers and others, it was deemed advisable for senior management and Wachovia to limit their contacts with respect to a possible leveraged buyout transaction to a small number of financial sponsors and to not contact potential strategic acquirors.

Accordingly, in May 2006, members of senior management of the Company identified investment banking and private equity firms whom the Company could potentially contact to discuss financing and other strategic alternatives involving the Company. In selecting the private equity firms to contact, senior management focused on those firms' prior interest in the Company and/or their previous experience in sponsoring buyouts in the technology sector.

During early June 2006, senior management contacted senior representatives at four private equity firms, including Carlyle and Providence, about a potential transaction with the Company. Three of the four firms contacted by senior management expressed an interest in learning more about a potential transaction and having meetings with members of management. The discussions with the three firms were general in nature, focusing, among other things, on their interest in the Company and its industry and the buyout process. Around this time, senior management provided to each of the three firms certain previously prepared projections related to the future financial performance of the Company, which were subsequently provided to and used by SunTrust Robinson Humphrey as described in "—Opinion of SunTrust Robinson Humphrey" below. Based on their general discussions with senior management, the projections and public information, each of Carlyle and Providence verbally indicated the valuation ranges for 100% of the stock of the Company which they might be willing to offer; Carlyle provided a non-binding indication of interest to acquire the Company at a range of $31.00 to $34.00 per share, and Providence provided a non-binding indication of $35.00 to $37.00 per share. The third private equity firm, which we refer to as Firm 3, did not provide a valuation range at this time. Carlyle and Providence stressed that further due diligence would need to be conducted to confirm and revise these initial indications of interest. The fourth private equity firm declined to continue further discussions with the Company regarding a potential leveraged buyout transaction due to concerns regarding valuation uncertainty surrounding the Company's recent acquisition of the Information Services Group of The BISYS Group, Inc. and the success of such acquisition's integration into the Company's broader operations.

In late July, Wachovia provided management with an update on potential strategic acquisition opportunities then in the market and discussed with management generally the Company's business strategy and recent steps undertaken to explore strategic alternatives to enhance value for the Company's stockholders, including the initial contacts with the aforementioned private equity firms. Wachovia and management discussed in further detail trends in leveraged buyout transactions, the increased activity of private equity sponsors, and historically positive conditions in the leveraged lending markets. Wachovia noted that the Company may benefit from several aspects of undertaking a leveraged buyout and operating as a private company, including the ability to grow at a pace, organically and through strategic acquisitions, required to capture market opportunity and scale in the financial technology sector, the capacity to focus on a long-term strategic plan as opposed to short-term stock price fluctuations and the opportunity to provide significant value to stockholders given the current environment for leveraged buyout transactions.

At a meeting of the board of directors on July 28, 2006, members of senior management updated the board of directors with respect to the steps management had recently undertaken in furtherance of the Company's exploration of strategic alternatives, including the discussions with the potential financial sponsors, including Carlyle and Providence. Senior management indicated to the board of directors that both senior management and the potential financial sponsors would need to proceed with further discussions and due diligence on a more detailed level in order to confirm the viability of any such potential transaction between the parties. At that meeting, in order to assist the Company in its acquisition growth strategy and to allow the Company greater flexibility to meet its current and future capital requirements, the board of directors of the Company authorized the preparation and filing with the SEC of a universal shelf registration statement covering the issuance of debt and equity securities by the Company. The board also authorized senior management to continue its discussions with the financial sponsors and permit them to conduct detailed due diligence.

At a meeting of the board of directors on August 4, 2006, members of senior management updated the board of directors on two potential strategic acquisitions the Company was exploring and other strategic alternatives to enhance stockholder value, including the proposed timeframe for the three private equity firms to confirm the viability of any such potential transaction between the parties. During the first half of August 2006, the three remaining private equity firms, including Carlyle and Providence, executed non-disclosure and standstill agreements with the Company in order to perform due diligence. In addition, in mid- to late-August each of the three firms met with Wachovia and members of management to discuss the Company's operations and financial performance. Throughout August, the Company continued, with the assistance of Wachovia, to pursue the potential acquisition opportunities referred to earlier. Around this time, Kenneth Saunders, the Company's Chief Financial Officer, had general discussions with Carlyle, Providence and Firm 3 discussing, among other things, the buyout process and each firm's equity financing capabilities, and asked each firm about its general philosophy regarding the oversight and operation of portfolio companies and incentivizing management. During such discussions with Mr. Saunders, each of Carlyle and Providence mentioned the possibility of employment agreements for one or more officers and management representation on the acquiror's board and stated generally that it anticipated making available to certain members of management stock options exercisable, subject to the satisfaction of conditions, into up to 15% of the acquiror's shares of common stock outstanding on a fully diluted basis and the opportunity to exchange, simultaneously with the consummation of the merger, some of their Company securities for securities of the acquiror. Each of Providence and Carlyle cited a recent publicly disclosed transaction in which it had participated as typical of its approach.

On August 31, 2006 and September 1, 2006, on the instructions of Wachovia, each of Carlyle, Providence and Firm 3 provided Wachovia and management with feedback regarding valuation and the principal terms of a potential buyout transaction involving the Company. During this period, Carlyle provided a revised non-binding indication of interest at an increased price of $36.00 per share, Providence revised its indication of interest to the high end of its previous range of $37.00 per share, and Firm 3 provided a non-binding indication of interest for $34.00 per share. Included in Carlyle's indication of interest was the requirement that the Company would be generally prohibited from soliciting competing offers upon execution of a proposed merger agreement, along with certain other conditions to consummation of the potential transaction. While Providence's indication of interest also included certain conditions to consummation of a potential transaction, its indication of interest indicated that Providence would be amenable to allowing the Company a post-signing market check to solicit alternative offers to acquire the Company.

A meeting of the board of directors was held on September 6, 2006. In addition to the members of the board, attending the meeting at the invitation of the board were certain members of senior management of the Company, along with a representative of Simpson Thacher & Bartlett LLP, which we refer to as Simpson Thacher, the Company's outside legal counsel, and representatives of Wachovia. At the meeting, Wachovia and management updated the board of directors on the Company's activities with respect to strategic alternatives to enhance stockholder value, including the discussions that had taken place to date with the private equity firms with respect to the exploration of the feasibility and terms and conditions surrounding a possible leveraged buyout transaction involving the Company. Wachovia then reviewed in detail its presentation relating to a potential transaction involving the private equity firms, including Providence and Carlyle, and provided a summary of certain key terms of the indications of interest submitted by Providence, Carlyle and Firm 3. Wachovia reviewed various transaction rationales, including the potential benefits of a leveraged buyout transaction relative to other strategic alternatives, such as growth through acquisitions as a public company. Wachovia noted that despite the Company's recent favorable financial performance, including strong market share gains, above market organic growth and favorable recurring cash flow, the Company's recent stock price performance relative to its industry peers had not been as favorable. Coupled with this discussion of strategic alternatives, Wachovia provided its analyses of the Company's valuation and compared the

financial terms offered by the private equity firms with those existing in similar precedent transactions. Wachovia responded to questions from members of the board of directors. Following this discussion, Wachovia then discussed possible next steps. In particular, Wachovia recommended that the indications of interest submitted by Providence and Carlyle could be improved if each of those parties was permitted to contact and work with other sources of equity financing, which was prohibited under the terms of the non-disclosure agreement that each party had signed. Specifically, Wachovia noted that if those parties were permitted to share the equity financing risk with another party they might be able to increase their price by a greater amount than otherwise would be the case, and greater certainty of financing might be achieved. Wachovia and management also advised the board of directors of each firm's request to perform further due diligence to confirm their views on valuation and the Company's operations. Upon request of the board of directors, Simpson Thacher reviewed the board's fiduciary obligations under Delaware law. The board proceeded to discuss Wachovia's recommendation, following which the board of directors authorized management and the Company's advisors to continue their investigation of a possible acquisition transaction involving the corporation and to continue their discussions with the potential purchasers. The board of directors stressed, however, that it would be willing to proceed in considering a possible transaction only if the financial and other terms of the proposal were sufficiently attractive to the Company's stockholders, including a process by which the board of directors could solicit and accept alternative proposals for the acquisition of the Company after the execution of a definitive agreement with any potential acquiror, due in part to the concerns discussed above relating to the potential adverse impacts of leaks and the disclosure of confidential information to competitors. Because the indication of interest submitted by Firm 3 was well below those submitted by Providence and Carlyle, and such firm had verbally indicated to Wachovia its inability to submit a substantially improved offer, the board of directors decided to discontinue further discussions with Firm 3 and focus on the offers of Carlyle and Providence. In order to further its objectives to enhance stockholder value, the board resolved to unanimously waive the provision prohibiting discussions with other sources of equity financing in the confidentiality agreements between the Company and each of Providence and Carlyle to permit them to have discussions with other sources of equity financing, including each other, in order to determine whether the bids of each of these firms could be improved. After the discussion of the potential buyout transaction concluded, the board proceeded with its normal business, including receiving an update from management with respect to the Company's ongoing acquisition activities.

Following the meeting, Wachovia separately informed each of Providence and Carlyle that it needed to increase its price and improve other terms of its previous indication of interest and that the Company had decided to waive the provision of the non-disclosure agreements signed by each party which would otherwise have prohibited them from having discussions with one another, and that they therefore should speak with each other and work together to increase their price and improve their other terms.

On September 8, 2006, another special meeting of the board was held, with a representative of Simpson Thacher in attendance. At the meeting, Wachovia updated the board of directors on its discussions with Providence and Carlyle regarding the potential leveraged buyout transaction involving the Company. Providence and Carlyle each informed Wachovia that they had discussed the proposed transaction with the other, including the possibility of submitting a joint proposal, and anticipated that the joint proposal would include, among other things, a purchase price of $37.50 per share for all of the common stock of the Company, a mutually acceptable reverse breakup fee, provisions permitting the Company to solicit competing acquisition proposals and provide confidential information or enter into negotiations with such persons for a limited period of time, and a limited time period for Providence and Carlyle to complete due diligence and negotiate a mutually acceptable definitive agreement. Following discussion, the board of directors agreed to direct Wachovia to inform each of Providence and Carlyle that the board was willing to consider a joint proposal if it was submitted to the board of directors in writing.

Following this discussion, the representative of Simpson Thacher discussed with the board of directors whether the formation of a special committee of the board of directors, consisting of independent and disinterested directors, was desirable in connection with the board of directors' consideration of the proposed transaction. In light of the possibility that Mr. Hernandez and/or other members of senior management might participate in any potential transaction involving the private equity firms, through an equity commitment or otherwise, the board of directors and the representative of Simpson Thacher noted that establishing a special committee comprised of directors who were independent of the Company and which would exclude Mr. Hernandez would be beneficial if management were to participate in the transaction. Simpson Thacher then discussed in further detail with the board of directors their fiduciary duties in considering the proposed transaction and the possible role of and benefits of appointing a special committee of independent and disinterested directors to entertain, negotiate and/or recommend the approval of the proposed transaction on behalf of the Company. Simpson Thacher then made inquiries into the independence of the members of the board of directors and reminded the directors of their previous discussions concerning their fiduciary duties. The representative of Simpson Thacher also advised the board of directors that Simpson Thacher had in the past and continues to represent many private equity sponsor clients, including Carlyle and Providence. Following discussion by the board and Simpson Thacher, the board of directors unanimously adopted resolutions to create a special committee, comprised of Douglas K. Anderson, Howard L. Carver, Dennis P. Lynch, Samuel F. McKay, Carlos P. Naudon and Richard P. Yanak. The board of directors authorized the special committee to take any and all actions necessary or advisable in connection with the receipt, evaluation, negotiation, response, rejection, and, if appropriate, the agreement, or recommendation to or of the board of directors regarding the agreement, of a proposed transaction to acquire the Company. The board of directors further authorized and directed the special committee to retain independent financial, legal and other advisors as the special committee felt necessary or advisable to perform its functions.

Upon conclusion of the meeting of the full board of directors, a meeting of the special committee was held on September 8, 2006 at which a representative from Simpson Thacher was invited. The representative of Simpson Thacher discussed with the special committee the possibility of authorizing the reimbursement of legal expenses incurred by senior management in connection with any arrangements which may be made between senior management and the potential bidders. The representative of Simpson Thacher discussed the need for management to retain outside legal counsel experienced in that context and the commercial precedent in respect of companies reimbursing management for such expenses. Simpson Thacher discussed further the possible timing and impact on the sales process of such negotiations and noted that the potential purchasers might insist on discussions with management as a condition to execution of a definitive agreement. While the representative of Simpson Thacher indicated that having management prepared should help to minimize possible delays in finalizing and executing a definitive agreement to acquire the Company, he noted in that regard that the special committee should control the timing and scope of discussions between the potential acquirors and management and that the special committee would likely want to prohibit management from engaging in those negotiations until later in the process. Following a discussion by the special committee of the matters presented, during which the representative of Simpson Thacher responded to questions, the special committee approved the reimbursement of certain legal expenses incurred by senior management in connection with any negotiations with prospective purchasers in respect of a potential transaction, but did not authorize management to undertake negotiations with Providence and Carlyle at this time. The special committee then determined to retain its own legal and financial advisors and authorized Mr. Anderson to act on behalf of the special committee to identify potential candidates.

From September 8 to September 11, 2006, Mr. Anderson identified several investment banks, including SunTrust Robinson Humphrey, and several law firms, including Morris, Nichols, Arsht & Tunnell, which we refer to as Morris Nichols, as potential advisors to the special committee. During

this time period, representatives of Carlyle and Providence and their financial and legal advisors continued their due diligence review of the Company.

On September 11, 2006, a meeting of the special committee was held, with certain members of senior management and representatives of Simpson Thacher in attendance at the request of the special committee. Mr. Anderson discussed his consideration and interview of potential special counsel and independent investment bankers to represent the special committee. Mr. Anderson reported the results of his discussions with these potential advisors, specifically with a representative of Morris Nichols and a representative of SunTrust Robinson Humphrey. After discussion, the special committee resolved to appoint Morris Nichols as legal counsel to the special committee and SunTrust Robinson Humphrey as financial advisor to the special committee, subject to reaching mutually agreeable terms of engagement letters with each advisor, which was subsequently achieved. The special committee directed that, when negotiations commenced with the sponsors' advisors, Morris Nichols should coordinate with Simpson Thacher with respect to such negotiations on behalf of the special committee and the Company.

On September 12, 2006, Carlyle and Providence submitted a written proposal to the Company relating to a potential acquisition of the Company at $37.50 per share in cash. In submitting its proposal, the Sponsors expressed the desire to complete their due diligence and sign a definitive agreement promptly, and separately instructed their advisors to provide the Company and Wachovia with additional requests relating to due diligence.

A meeting of the special committee was held on September 14, 2006, at which certain members of senior management, and representatives of each of Morris Nichols, Simpson Thacher, Wachovia and SunTrust Robinson Humphrey were present, to discuss the revised joint proposal submitted by the Sponsors. At the meeting, SunTrust Robinson Humphrey presented a preliminary analysis of the Company's valuation, an overview of the financial technology market in general, and an initial review of potential parties that might have an interest in acquiring the Company. Following this discussion, Mr. Hernandez and the other members of management and representatives of Simpson Thacher, Wachovia and SunTrust Robinson Humphrey left the meeting at the request of the special committee. A representative of Morris Nichols then reviewed the fiduciary duties of the members of the special committee in connection with a possible transaction, emphasizing the importance of the process leading to a transaction, including the importance of providing for an effective post-signing market check conducted by the financial advisor to the special committee. The special committee noted that it understood that the Sponsors had agreed in concept to such go shop period.

Over the course of the next several days, representatives of SunTrust Robinson Humphrey conducted a due diligence review of the Company's business and prospects with members of senior management of the Company.

The advisors to the special committee and the Company received from the Sponsors' advisors a draft of the merger agreement on September 18, 2006. During the week of September 18, 2006, representatives of the Sponsors and their financial and legal advisors met with management of the Company and Wachovia to discuss due diligence and related matters. On September 18, 2006 the non-disclosure agreements executed by Carlyle and Providence were amended to permit them to confer with certain specified potential sources of debt financing and a financial advisor and to confirm that they were prohibited from having discussions with sources of equity financing other than each other.

On September 21, 2006, the special committee held a meeting at which Mr. Hernandez and other members of senior management, a representative of Morris Nichols and representatives of each of Simpson Thacher and SunTrust Robinson Humphrey were present. At the meeting, Mr. Hernandez described the due diligence meetings earlier in the week between management and the Sponsors. Mr. Hernandez and the other members of management then excused themselves from the meeting at the request of the special committee. Thereafter, a representative of Morris Nichols again reviewed with the special committee its fiduciary duties with respect to a potential transaction. After a discussion

of those principles and their application to the transaction, representatives of Morris Nichols and Simpson Thacher discussed with the special committee their expectations concerning the key terms of the merger agreement to be negotiated with the Sponsors, how those expectations differed from the initial draft of the merger agreement distributed by the Sponsors' advisors, the anticipated timing of the negotiation of a definitive agreement and other matters. In particular, Morris Nichols and Simpson Thacher noted that the initial draft received from the Sponsors' advisors included several provisions relating to the conditionality of Sponsors' obligations to complete the transaction, including the receipt of certain third party consents, the absence of 5% or more of the stockholders of the Company exercising their appraisal rights under Delaware law and the Sponsors' receipt of debt financing necessary to pay the merger consideration and related fees and expenses. In addition, it was noted that while the Sponsors' draft included provisions permitting the Company to solicit alternative acquisition proposals for a limited period after execution of the merger agreement, the conditions pursuant to which such solicitations were allowed were relatively restrictive, and furthermore, the Sponsors' draft only provided for a post-signing solicitation period of 15 days and did not permit the Company to terminate the merger agreement in connection with a superior proposal. Furthermore, the Sponsors' draft provided for a single termination fee amount to be paid by the Company during certain circumstances. The special committee discussed at length the interplay of the go shop period, the appropriate length of such period necessary in order to perform an effective market check and the breakup fee that would be payable if the Company terminated the agreement to enter into a superior transaction. The special committee also discussed with Morris Nichols the point in the negotiations at which the special committee would permit management to commence negotiations with the Sponsors regarding the terms of their employment arrangements and equity participation in the surviving corporation. Representatives of Morris Nichols suggested to the special committee members that such approval was more appropriate for a later stage in the process. After the foregoing discussions, at Morris Nichols' request, SunTrust Robinson Humphrey reviewed its preliminary financial analyses. After completing this review and answering the questions of special committee, SunTrust Robinson Humphrey reviewed with the special committee a list of parties that might be contacted during the go shop period were a transaction to be eventually entered into between the Company and the Sponsors.

Representatives of Morris Nichols and Simpson Thacher held a conference call with representatives of Latham & Watkins LLP, or Latham, legal advisor to the Sponsors, on September 26, 2006, to negotiate the terms and conditions of the proposed merger agreement. SunTrust Robinson Humphrey and senior management continued SunTrust's due diligence review of the Company.

Two days later, on September 28, 2006, the special committee held another special meeting at which certain members of senior management and representatives of each of Morris Nichols, Simpson Thacher and SunTrust Robinson Humphrey were present. At the meeting, SunTrust Robinson Humphrey discussed again with the special committee its preliminary financial analyses and provided an update on the progress of its due diligence. A representative of Morris Nichols then updated the special committee on the negotiations held earlier in the week with Latham. The representative of Morris Nichols noted that the positions of the Company and the Sponsors with respect to many provisions of the merger agreement were similar and could be resolved relatively quickly through negotiation, but that the Company and Sponsors' difference in positions with respect to, among other issues, deal protection measures, the length of the post-signing solicitation period, the termination fee associated with termination of the agreement in connection with a superior proposal, and closing conditions remained significant. Following a long discussion regarding the Sponsors' proposals, members of senior management were excused, at which point the special committee discussed, among other matters, the special committee's proposed response to the Sponsors' proposals, specifically focusing on the length of the post-signing go-shop period, the amount of the termination fee associated with acquisition proposals entered into as a result of the post-signing go-shop period, and the possibility of seeking a price increase. After considering its strategy in pursuing negotiations with the Sponsors, the special committee determined to delay responding to the proposals until SunTrust Robinson

Humphrey fully completed its due diligence in order that the special committee's response might reflect the more informed advice of its financial advisor.

During early October, SunTrust Robinson Humphrey completed its due diligence of the Company and had general discussions with the Sponsors and Merrill Lynch, financial advisor to the Sponsors, relating to the terms of a proposed transaction. In particular, with respect to the length of the go-shop period, the Sponsors and Merrill Lynch stressed the Sponsors' desire for a short go-shop period.

A meeting of the special committee was held on October 3, 2006. In addition to members of the special committee, Mr. Hernandez and other members of senior management and representatives of each of Morris Nichols, Simpson Thacher and SunTrust Robinson Humphrey were in attendance. A representative of SunTrust Robinson Humphrey updated the special committee on its financial due diligence of the Company, noting that it had reviewed in detail and with members of management the Company's recent financial performance and the financial projections that had been provided to the Sponsors in connection with the potential transaction. SunTrust Robinson Humphrey indicated that its financial analysis had not changed significantly from its preliminary analysis based on its due diligence review of the Company and discussions with management. Mr. Hernandez then further discussed the Company's financial performance for 2006, including its performance to date in the third fiscal quarter. Following discussion with the special committee during which Mr. Hernandez and other members of senior management answered questions from the special committee, Mr. Hernandez and the other members of senior management then left the meeting at the request of the special committee. A representative of Morris Nichols then explained that, although there were a number of open issues in the negotiations among the Company and the Sponsors, the three most significant issues were whether the special committee should seek an increase in the price-per-share to be received by Company stockholders in the transaction, the length of a post-signing go-shop period, and the termination fee to be paid in connection with acquisition proposals entered into as a result of the post-signing go-shop period, including whether a lower fee should be paid under such a scenario and what the amount of such a fee should be. At the request of the special committee, a representative of Simpson Thacher reviewed precedent transactions with respect to the length of the go-shop period, following which the special committee inquired from SunTrust Robinson Humphrey the number of days SunTrust Robinson Humphrey believed would be needed to run an effective market check during the go-shop period, to which SunTrust Robinson Humphrey responded that an effective market check could be completed in as short as a 21-day period, but that the Company should negotiate for a longer period if possible. After a lengthy discussion regarding the go-shop termination fee, the special committee also discussed whether or not to seek a price increase, at which point it was determined to ask for an increase in price.

Promptly following the conclusion of this meeting, advisors to the special committee and the Company requested that the Sponsors increase the price to be paid to the Company's stockholders and to improve the other terms of the Sponsors' proposal, including with respect to conditionality and the terms and conditions surrounding the proposed go-shop period and the amount of the termination fee to be associated with the period.

On October 10, 2006, representatives of SunTrust Robinson Humphrey held discussions with representatives of Merrill Lynch regarding certain principal business terms to the proposed transaction. During the discussion, Merrill Lynch indicated that the Sponsors were prepared to submit a revised proposal in response to the Company's current position that included a 25-day post-signing go-shop period, a $20 million go-shop termination fee, a $30 million termination fee to be paid by the Company where the go-shop termination fee would not otherwise apply, and a $30 million reverse termination fee payable by the Sponsors in the event they were unable to secure financing for the transaction. The Sponsors, through Merrill Lynch, did not offer an increase in price at this time, but indicated that perhaps an increase of $0.25 per share could be possible if the other terms of the Sponsors' proposal were agreed to. Shortly after this discussion, members of Simpson Thacher discussed the Sponsors' revised proposal with representatives of Latham in order to clarify certain details with respect to the legal aspects of such proposal.

Later in the evening, on October 10, 2006, the special committee held a special meeting which members of senior management, Morris Nichols, Simpson Thacher and SunTrust Robinson Humphrey attended. A representative of SunTrust Robinson Humphrey recounted for the special committee the earlier conversation with Merrill Lynch. After senior management was excused from the meeting, a lengthy discussion regarding the Sponsors' offer ensued, including the advisors' views of such proposal and its comparison with precedent transactions. In particular, the special committee discussed with its advisors the likelihood of a bidder arising during the go-shop period, whether that bidder was more likely to be a financial sponsor or strategic bidder, and the deterrent effect the go-shop termination fee would have on such bidder. The advisors to the special committee and the Company advised the special committee to make a counterproposal including both an increased price per share and a lower go-shop termination fee. Following discussion, the special committee authorized its advisors to indicate to the Sponsors that the special committee would accept the 25-day go-shop period, the $30 million non-go-shop termination fee, and the $30 million reverse termination fee, but as a result of such concessions would require an increase in price and a lower go-shop termination fee. Prior to conclusion of the meeting, the special committee inquired whether it should release members of management to commence negotiations with the Sponsors with respect to any equity and employment arrangements to be entered into in connection with the transaction, to which the representatives of Morris Nichols and Simpson Thacher advised that it should not do so until after resolution of the primary business issues.

Following the meeting, that evening and early the next day, representatives of SunTrust Robinson Humphrey and Simpson Thacher separately relayed to the Sponsors' financial and legal advisors, respectively, the special committee's response to the Sponsors' earlier proposal and discussed with such advisors the details of such proposals. As part of these discussions, Merrill Lynch, on behalf of the Sponsors, submitted to SunTrust Robinson Humphrey a revised proposal with respect to the significant outstanding business issues. With respect to the go-shop termination fee associated with competing acquisition proposals arising from the post-signing go-shop period, Merrill Lynch indicated that the Sponsors would agree to reduce their proposed go-shop termination fee to $12 million, but would require the Company to terminate the transaction and enter into the alternative transaction within the 25-day post-signing go-shop period for such fee to apply, as opposed to requiring the Company to begin negotiations with respect to a competing acquisition proposal during the go-shop period for the go-shop termination fee to apply (as had been proposed by the special committee and its advisors). In addition, Merrill Lynch signaled to SunTrust Robinson Humphrey that the Sponsors would be willing to increase the price-per-share being paid to the Company's stockholders by $0.25 to $37.75.

A meeting of the Special Committee was held on October 11, 2006 to report on the Sponsors' revised proposal. After SunTrust Robinson Humphrey finished its report, at the request of the special committee, a representative of Simpson Thacher discussed the history of negotiations surrounding the go-shop termination fee. In addition, the representative of Simpson Thacher reported on other significant outstanding legal issues that remained open. In particular, it was noted that the Sponsors continued to seek a condition to their obligation to close the transaction tied to the absence of a percentage of Company stockholders seeking appraisal of their shares as a result of the transaction. Members of senior management were then asked to leave the meeting, at which point a discussion of the Sponsors' revised proposal ensued, focusing on the advisability of seeking a further price increase and reducing the amount of the go-shop termination fee. The special committee instructed its advisors to request an increase in the price per share to be paid to the Company's stockholders, a lower go-shop termination fee and other concessions relating to improved certainty of closing, and to ask the Sponsors to respond by 11:00 a.m. Eastern Time the next day, at which time the special committee was already scheduled to meet.

During the meeting of the special committee the following day, at which members of senior management and representatives of each of Morris Nichols, Simpson Thacher and SunTrust Robinson Humphrey were present, representatives of SunTrust Robinson Humphrey reported to the special committee its conversation with the Sponsors and their advisors earlier in the day, at which time the

Sponsors had agreed to raise the consideration to be paid to Company stockholders to $38.00 per share. In addition, representatives of SunTrust Robinson Humphrey also noted that the Sponsors agreed to accept the Company's position with respect to the remaining significant open issues with respect to conditionality of the transaction reflected in the draft merger agreement, including the Company's revised position with respect to the definition of a "company material adverse effect" in the merger agreement and the deletion of any closing condition tied to the number of Company stockholders seeking appraisal of their shares as a result of the transaction. SunTrust Robinson Humphrey informed the Special Committee that the Sponsors were, however, continuing to insist on the $12 million go shop termination fee and the related triggers applying to such fee. After confirming with SunTrust Robinson Humphrey its opinion that an effective market check during the post-signing go-shop period given the structure of the go-shop termination fee could be performed and a discussion of the revised proposal, the special committee then authorized its advisors to proceed with resolving all open issues and finalizing the proposed merger agreement. During this time, the special committee also resolved to permit management of the Company to negotiate with the Sponsors the terms of any proposed employment or equity arrangements in the surviving corporation, and instructed SunTrust Robinson Humphrey to indicate to the Sponsors that it had done so. However, the Sponsors and management did not conduct any such negotiations prior to the execution and delivery of the merger agreement.

Over the remainder of October 12, 2006 and for the following two days, representatives of Morris Nichols and Simpson Thacher negotiated with Latham to finalize the terms of the merger agreement and related agreements, including equity and debt commitment letters and guarantees executed by the Sponsors guaranteeing the payment of the reverse termination fee if payable by the Parent.

On October 14, 2006, meetings of both the special committee and full board of directors were held. In attendance were members of senior management and representatives of Morris Nichols, Simpson Thacher and SunTrust Robinson Humphrey. During the meeting, a representative of Morris Nichols reviewed the terms of the merger agreement with the board of directors, and noted that the changes which had been previously agreed upon were reflected in the final version of the merger agreement, which had been distributed to the members of the special committee along with other materials prior to the special meeting. It was noted that while management had been permitted to speak with the sponsors regarding employment and equity arrangements in the surviving corporation, no such negotiations occurred. A representative of SunTrust Robinson Humphrey then discussed with the special committee its analyses of the transaction and the price to be received by the Company's stockholders in the transaction, following which SunTrust Robinson Humphrey provided orally to the special committee its opinion (which opinion was subsequently confirmed in writing) that the transaction was fair from a financial point of view to the common stockholders of the Company. With the benefit of these presentations and advice, the special committee, having deliberated regarding the terms of the proposed transaction, unanimously resolved that the merger agreement is fair to and in the best interests of the Company and its stockholders and recommended that the board of directors of the Company approve the transaction, the merger agreement and the transactions contemplated by the merger agreement, and that the board of directors of the Company recommend to the stockholders of the Company that they vote to adopt the merger agreement. The special committee also recommended that the stockholders vote to adopt the merger agreement.

The meeting of the special committee was then adjourned and the meeting of the board of directors was reconvened. Following receipt of the special committee's recommendation to our board of directors, the board of directors unanimously determined that the merger agreement is fair to and in the best interests of the Company and its stockholders, approved the transaction, the merger agreement and the transactions contemplated by the merger agreement and declared their advisability and recommended that the stockholders of the Company vote to adopt the merger agreement.

The representative of SunTrust Robinson Humphrey then provided the board of directors with a brief summary of its process relating to the go-shop period provided for in the merger agreement. After responding to questions, the meeting was adjourned.

Following the meeting of the board of directors, the merger agreement, dated as of October 14, 2006, was executed by the Company, Parent and Merger Co. On October 16, 2006, prior to the opening of trading on NASDAQ, the Company, Providence and Carlyle issued a joint press release announcing the transaction. Beginning on October 16, 2006, under the supervision of the special committee, representatives of SunTrust Robinson Humphrey contacted parties that they believed would be capable of, and might be interested in, consummating an acquisition of the Company. On October 17, 2006, the Company filed a Current Report on Form 8-K which included copies of the merger agreement and the joint press release and summarized material terms of the merger agreement, including the go-shop and termination fee provisions.

During the period from October 16, 2006 through November 8, 2006, under the supervision of the special committee, representatives of SunTrust Robinson Humphrey contacted 12 potential strategic acquirors and 13 potential financial acquirors. Of these 25 parties, three eventually entered into a non-disclosure and standstill agreement with the Company. However, as of the end of the solicitation period on November 8, 2006 and to date, no party has submitted a proposal to pursue a transaction involving the Company.

Reasons for the Merger; Recommendation of the Special Committee and of Our Board of Directors

The Special Committee

The special committee, acting with the advice and assistance of its independent legal and financial advisors and the Company's outside counsel, evaluated and negotiated the merger proposal, including the terms and conditions of the merger agreement, with Parent and Merger Co. The special committee unanimously resolved to recommend to our board of directors that (i) the board approve the merger agreement, the merger and the transactions contemplated thereby and (ii) the board recommend to our stockholders that they vote to adopt the merger agreement.

In the course of reaching its determination, the special committee considered the following substantive factors and potential benefits of the merger, each of which the special committee believed supported its decision:

•: its belief, after a thorough, independent review, that the merger was more favorable to stockholders than the potential value that might result from other alternatives available to the Company, including remaining an independent company and pursuing the current strategic plan, pursuing acquisitions, pursuing a leveraged buyout transaction with private equity firms other than the Sponsors, or pursuing a sale to or merger with a company in the same or a related industry, given the potential rewards, risks and uncertainties associated with those alternatives;
•: its familiarity with the business, operations, properties and assets, financial condition, business strategy, and prospects of the Company (as well as the risks involved in achieving those prospects), the nature of the industry in which the Company competes, industry trends, and economic and market conditions, both on a historical and on a prospective basis;
•: its belief that no other alternative reasonably available to the Company and its stockholders would provide greater value to stockholders within a timeframe comparable to that in which the merger is expected to be completed, and the fact that the cash merger price of $38.00 per share allows the Company's stockholders to realize in the near term a value, in cash, for their investment that is fair and provides such stockholders certainty of value for their shares;

•: the current and historical market prices of the Company common stock relative to those of other industry participants and general market indices, and the fact that the $38.00 merger consideration represents a premium of approximately 31.7% over the average closing price of the Company common stock for the 30-day period prior to announcement of the proposed merger and a premium of approximately 25.5% over the closing price of the Company common stock on the last trading day prior to the public announcement of the proposed merger;
•: the fact that the stockholders will be able to decide for themselves at the special meeting whether to approve the adoption of the merger agreement;
•: its belief that, by permitting Carlyle and Providence to submit a joint bid, the $38.00 merger consideration is above what each of Carlyle and Providence would likely have bid if it acted alone;
•: the fact that the $38.00 merger consideration is at the high end of, or above, many of the valuation ranges arrived at through the various methodologies employed by SunTrust Robinson Humphrey in its analyses;
•: the fact that the terms of the merger agreement provide for a 25 day post-signing go-shop period during which the Company was permitted to, and did, solicit additional interest in transactions involving the Company, and, after such 25 day period, is permitted to continue discussions with certain persons or respond to unsolicited proposals under certain circumstances;
•: the fact that the merger consideration is all cash, so that the transaction allows the Company's stockholders to immediately realize a value, in cash, for their investment that is fair and provides such stockholders certainty of value for their shares;
•: the financial presentations of SunTrust Robinson Humphrey and its opinion that, as of October 14, 2006, the consideration to be received by the stockholders of the Company in the merger is fair to such holders from a financial point of view;
•: the efforts made by the special committee and its advisors to negotiate a merger agreement favorable to the Company and its stockholders and the financial and other terms and conditions of the merger agreement, including the fact that the merger agreement would not be subject to a financing condition;
•: the level of effort that the Sponsors must use under the merger agreement to obtain the proceeds of the financing on the terms and conditions described in the Sponsors' commitment letters;
•: the fact that, subject to compliance with the terms and conditions of the merger agreement, the Company is permitted to terminate the merger agreement, prior to the adoption and approval of the merger agreement by our stockholders, in order to approve an alternative transaction proposed by a third party that is a "superior proposal" as defined in the merger agreement, upon the payment to the Sponsors of either (i) a $30 million termination fee, or (ii) if the Company had terminated the merger agreement in order to enter into a definitive agreement with respect to a superior proposal on or prior to November 8, 2006, a $12 million termination fee, and its belief that such termination fees are reasonable in the context of break-up fees that were payable in other transactions and would not preclude another party from making a competing proposal;
•: the fact that, in the event of a failure of the merger to be consummated under certain circumstances, a $30 million termination fee would be payable by Parent, eliminating the need for the Company to have to establish damages; and

•: the availability of appraisal rights to holders of the Company's common stock who comply with all of the required procedures under Delaware law, which allows such holders to seek appraisal of the fair value of their shares as determined by the Delaware Court of Chancery.

The special committee also considered a number of factors relating to the procedural safeguards involved in the negotiation of the merger, including those discussed below, each of which it believed supported its decision and provided assurance of the fairness of the merger to the stockholders of the Company:

•: the fact that the special committee is comprised solely of independent and disinterested directors who are not employees of the Company and who have no financial interest in the merger that is different from that of our stockholders and that the special committee is comprised of all of our directors other than Mr. Hernandez;
•: the fact that the special committee had ultimate authority to decide whether or not to proceed with a transaction or any alternative thereto, subject to our board of directors' approval of the merger agreement;
•: the fact that the financial and other terms and conditions of the merger agreement were the product of arm's-length negotiations between the special committee and its advisors, on the one hand, and the Sponsors and their advisors, on the other hand;
•: the fact that the special committee retained and received advice from its own independent legal counsel and financial advisor in evaluating, negotiating and recommending the terms of the merger agreement;
•: the fact that neither Mr. Hernandez nor other members of senior management were released by the special committee to negotiate the terms of their employment arrangements with the Sponsors and their possible equity investment in our Company following the closing until the Company and the Sponsors had reached resolution on key business issues and only two days before the merger agreement was approved and signed;
•: the fact that the opinion of SunTrust Robinson Humphrey addresses the fairness, from a financial point of view, of the merger consideration to be received by stockholders;
•: the fact that the Company is permitted under certain circumstances to solicit and respond to inquiries regarding acquisition proposals and, upon payment of a termination fee, to terminate the merger agreement in order to complete a superior proposal; and
•: the fact that under Delaware law, the stockholders of the Company have appraisal rights with respect to their shares.

The special committee also considered a variety of risks and other potentially negative factors concerning the merger agreement and the merger, including the following:

•: the possibility that the Sponsors will be unable to obtain the financing proceeds, including obtaining the debt financing proceeds from its lenders;
•: the risks and costs to the Company if the merger does not close, including the diversion of management and employee attention, employee attrition and the effect on business and customer relationships;
•: the fact that the Company's stockholders will not participate in any future earnings or growth of the Company and will not benefit from any appreciation in the value of the Company, including any value that could be achieved in the event the Company is acquired in the future by a strategic buyer or as a result of improvements to the Company's operations;

•: Mr. Hernandez's and certain other members of management's anticipated participation in the merger and the fact that Mr. Hernandez and such other members of management would have additional interests in the transaction that are different from, or in addition to, those of the Company's other stockholders;
•: the restrictions on the conduct of the Company's business prior to the consummation of the merger, requiring the Company to conduct its business in the ordinary course, subject to specific limitations, which may delay or prevent the Company from undertaking business opportunities that may arise pending completion of the merger;
•: the fact that an all-cash transaction would be taxable to the Company's stockholders that are U.S. persons for U.S. federal income tax purposes; and
•: the fact that the Company is entering into a merger agreement with a newly formed corporation with essentially no assets and, accordingly, that its remedy in connection with a breach of the merger agreement by Parent or Merger Co, even a breach that is deliberate or willful, is limited to $30 million.

The foregoing discussion summarizes the material factors considered by the special committee in its consideration of the merger. After considering these factors, the special committee concluded that the positive factors relating to the merger agreement and the merger outweighed the potential negative factors. In view of the wide variety of factors considered by the special committee, and the complexity of these matters, the special committee did not find it practicable to quantify or otherwise assign relative weights to the foregoing factors. In addition, individual members of the special committee may have assigned different weights to various factors. The special committee approved and recommended the merger agreement and the merger based upon the totality of the information presented to and considered by it.

Our Board of Directors

Our board of directors, acting in large part upon the unanimous recommendation of the special committee (whose members were all of the members of our board of directors other than Mr. Hernandez), and after careful deliberation, at a meeting described above on October 14, 2006, by unanimous vote (i) determined that the merger, the merger agreement and the transactions contemplated thereby, are advisable, fair to and in the best interests of the Company and our stockholders; (ii) approved the merger, the merger agreement and the transactions contemplated thereby and (iii) recommended that our stockholders adopt the merger agreement. In reaching these determinations, our board considered (i) the financial presentation of SunTrust Robinson Humphrey that was prepared for the special committee and which was delivered to the board of directors at the request of the special committee, as well as the fact that the special committee received an opinion delivered by SunTrust Robinson Humphrey as to the fairness, from a financial point of view, to the Company's stockholders of the merger consideration to be received by such holders in the merger and (ii) the unanimous recommendation and analysis of the special committee, as described above, and adopted such recommendation and analysis in reaching its determinations.

The foregoing discussion summarizes the material factors considered by our board of directors in its consideration of the merger. In view of the wide variety of factors considered by our board of directors, and the complexity of these matters, our board of directors did not find it practicable to quantify or otherwise assign relative weights to the foregoing factors. In addition, individual members of our board of directors may have assigned different weights to various factors. The board of directors approved and recommends the merger agreement and the merger based upon the totality of the information presented to and considered by it.

Our board of directors recommends that you vote "FOR" the adoption of the merger agreement.

Opinion of SunTrust Robinson Humphrey

The special committee retained SunTrust Robinson Humphrey to act as its financial advisor in connection with the merger. In connection with SunTrust Robinson Humphrey's engagement, the special committee requested that SunTrust Robinson Humphrey evaluate the fairness of the merger consideration, from a financial point of view, to Open Solutions' stockholders. On October 14, 2006, the special committee met to review the proposed merger and the terms of the proposed merger agreement. During this meeting, SunTrust Robinson Humphrey reviewed with the special committee certain financial analyses, as described below, and rendered its oral opinion to the special committee, which was subsequently confirmed in writing, that, as of October 14, 2006, and based upon and subject to the various considerations and assumptions described in the opinion, the merger consideration was fair, from a financial point of view, to Open Solutions' stockholders.

The full text of SunTrust Robinson Humphrey's opinion, dated October 14, 2006, which sets forth the procedures followed, assumptions made, matters considered and limitations on the review undertaken, is attached as Annex B and is incorporated into this proxy statement by reference. Holders of Open Solutions common stock are encouraged to read this opinion carefully in its entirety. SunTrust Robinson Humphrey's opinion was provided to the special committee in connection with its evaluation of the merger consideration to Open Solutions' stockholders. It does not address any other aspect of the proposed merger, relates only to the fairness, from a financial point of view, of the merger consideration and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the merger. The following is a summary of the SunTrust Robinson Humphrey opinion and is qualified by reference to the full text of the opinion attached as Annex B, which you are encouraged to read in its entirety.

In arriving at its opinion, SunTrust Robinson Humphrey, among other things:

•		reviewed and analyzed the merger agreement and certain other agreements related to the merger, including the equity commitment letters and related guarantees provided by the Sponsors;
•		reviewed publicly available information concerning Open Solutions which SunTrust Robinson Humphrey believed to be relevant;
•		reviewed and analyzed financial and operating information with respect to the business, operations and prospects of Open Solutions furnished by Open Solutions;
•		discussed the business, operations, assets, present condition and future prospects of Open Solutions with the management of Open Solutions and undertook such other studies, analyses and investigations as SunTrust Robinson Humphrey deemed appropriate;
•		reviewed the trading history of Open Solutions' common stock from November 2003 to October 12, 2006 and a comparison of that trading history with those of other publicly traded companies that SunTrust Robinson Humphrey deemed relevant;
•		compared the historical financial results and present financial condition of Open Solutions with those of publicly traded companies which SunTrust Robinson Humphrey deemed relevant;
•		reviewed and compared the financial terms of the merger with the publicly available financial terms of certain other recent transactions which SunTrust Robinson Humphrey deemed relevant;
•		reviewed and analyzed historical data relating to percentage premiums paid in acquisitions of publicly traded companies from November 2005 to October 12, 2006; and
•		reviewed other financial statistics and undertook such other analyses and investigations as SunTrust Robinson Humphrey deemed appropriate.

In arriving at its opinion, SunTrust Robinson Humphrey assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information discussed with or reviewed by SunTrust Robinson Humphrey. With respect to the financial forecasts of Open Solutions provided to or discussed with SunTrust Robinson Humphrey, SunTrust Robinson Humphrey assumed, at the direction of the special committee and without independent verification or investigation, that such forecasts have been reasonably prepared on bases reflecting the best currently available information, estimates and judgments of the management of Open Solutions as to the future financial performance of Open Solutions. In arriving at its opinion, SunTrust Robinson Humphrey did not conduct a physical inspection of the properties and facilities of Open Solutions and did not make or obtain any evaluations or appraisals of the assets or liabilities (including, without limitation, any potential environmental liabilities), contingent or otherwise, of Open Solutions. SunTrust Robinson Humphrey also assumed that the merger would be consummated in accordance with the terms of the merger agreement and related agreements. SunTrust Robinson Humphrey also assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on Open Solutions or on the expected benefits of the merger. SunTrust Robinson Humphrey's opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, October 14, 2006. SunTrust Robinson Humphrey expressed no opinion as to the underlying valuation, future performance or long-term viability of Open Solutions. Developments occurring after October 14, 2006 may affect SunTrust Robinson Humphrey's opinion, and SunTrust Robinson Humphrey did not assume any obligation to update or revise its opinion.

The special committee retained SunTrust Robinson Humphrey to act as its financial advisor and render a fairness opinion in connection with the merger. The special committee selected SunTrust Robinson Humphrey based on SunTrust Robinson Humphrey's qualifications, expertise and reputation. SunTrust Robinson Humphrey is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger and is continuously engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, secondary distributions of listed and unlisted securities and private placements. SunTrust Robinson Humphrey and its affiliates, including SunTrust Banks, Inc., in the future may provide investment banking and other financial services to Open Solutions. In the ordinary course of SunTrust Robinson Humphrey's trading and brokerage business, SunTrust Robinson Humphrey or its affiliates actively trade in the equity securities of Open Solutions for its own account and for the account of customers and, accordingly, may at any time hold a long or short position in such securities. During the past two years, SunTrust Robinson Humphrey has not provided financial advisory and financing services to Open Solutions or its affiliates other than with respect to the services rendered to the special committee in connection with the proposed merger.

Under the terms of its engagement letter entered into with the special committee in connection with the merger, SunTrust Robinson Humphrey provided the special committee financial advisory services and a fairness opinion in connection with the merger. In consideration of such services, SunTrust Robinson Humphrey will receive $500,000, which became payable upon delivery of SunTrust Robinson Humphrey's fairness opinion, plus $500,000 to be paid if the merger is consummated at the current price. SunTrust Robinson Humphrey would also earn additional compensation, subject to a maximum amount, if the merger is consummated at a price higher than the current merger price. Open Solutions has also agreed to reimburse SunTrust Robinson Humphrey for out-of-pocket fees and expenses, including attorney's fees, incurred in connection with its engagement and to indemnify SunTrust Robinson Humphrey and related parties against liabilities, including liabilities under the federal securities laws, arising out of its engagement.

In arriving at its opinion, SunTrust Robinson Humphrey was not authorized to solicit, and did not solicit, interest from any party with respect to the acquisition of Open Solutions or any of its assets, nor

did SunTrust Robinson Humphrey negotiate with any parties other than Parent with respect to a possible acquisition of Open Solutions or certain of its constituent businesses.

Financial Analyses

In preparing its opinion, SunTrust Robinson Humphrey performed a variety of financial and comparative analyses, a summary of which is described below. The summary of the analyses described below is not a complete description of the analyses underlying SunTrust Robinson Humphrey's opinion. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, SunTrust Robinson Humphrey made qualitative judgments as to the significance and relevance of each analysis and factor that it considered. SunTrust Robinson Humphrey arrived at its ultimate opinion based on the results of all analyses undertaken and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis. Accordingly, SunTrust Robinson Humphrey believes that its analyses must be considered as an integrated whole and that selecting portions of its analyses and factors, without considering all analyses and factors, could create a misleading or incomplete view of the processes underlying such analyses and SunTrust Robinson Humphrey's opinion.

In performing its analyses, SunTrust Robinson Humphrey made numerous assumptions with respect to Open Solutions, industry performance and general business, economic, market and financial conditions, many of which are beyond the control of Open Solutions. No company, transaction or business used in SunTrust Robinson Humphrey's analyses as a comparison is identical to Open Solutions, its business or the proposed merger, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions analyzed. The estimates contained in the analyses of SunTrust Robinson Humphrey and the valuation ranges resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by such analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty.

The merger consideration was determined through arm's-length negotiations between the special committee and the Sponsors and was recommended by the special committee for approval by Open Solutions' board of directors and was approved by the board of directors. SunTrust Robinson Humphrey provided advice to the special committee. SunTrust Robinson Humphrey did not recommend any specific merger consideration to the special committee or that any specific merger consideration constituted the only appropriate merger consideration for the merger. The opinions and financial analyses of SunTrust Robinson Humphrey were only one of many factors considered by the special committee in its evaluation of the proposed merger and should not be viewed as determinative of the views of the special committee, the board of directors or management with respect to the merger or the merger consideration.

The following is a summary of the material financial analyses underlying the opinion of SunTrust Robinson Humphrey and which were reviewed with the special committee on October 14, 2006. The financial analyses summarized below include information presented in tabular format. In order to fully understand SunTrust Robinson Humphrey's financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of SunTrust Robinson Humphrey's financial analyses.

Analysis of Transaction Price

SunTrust Robinson Humphrey analyzed the value of the consideration of $38.00 per share to be received pursuant to the merger agreement based on the premium to Open Solutions' historical stock prices, including Open Solutions' 52-week high and low closing stock price; Open Solutions' average stock price for the 30-day, 60-day, 90-day and last twelve months trading periods preceding October 12, 2006, the assumed announcement date of the merger; and Open Solutions' closing stock price for the one-day, one-week, 30-days, 60-days and 90-days prior to October 12, 2006. The results of this analysis are summarized below.

Metric		Statistic		Premium(1)

Market Analysis of Selected Publicly Traded Reference Companies

SunTrust Robinson Humphrey reviewed and compared publicly available financial data, market information and trading multiples for Open Solutions with other selected publicly traded reference companies that possess characteristics similar to Open Solutions' with respect to industry of operation, product profile, size or financial results. These companies are:

Financial Technology Companies:

CheckFree Corp. (CKFR)
Digital Insight Corp. (DGIN)
Fidelity National Information Services Inc. (FIS)
Fiserv Inc. (FISV)
John H Harland Co. (JH)
Jack Henry & Associates Inc. (JKHY)
Transaction Systems Architects Inc. (TSAI)

For the selected publicly traded companies, SunTrust Robinson Humphrey analyzed, among other things, firm value (or market capitalization plus debt less cash and cash equivalents) as a multiple of: last quarter annualized (which, with respect to the Company, refers to the Company's second fiscal quarter ended June 30, 2006), which SunTrust Robinson Humphrey refers to as LQA, and projected calendar year 2006 and 2007, which SunTrust Robinson Humphrey refers to as 2006E and 2007E, respectively, revenues; and LQA, 2006E and 2007E earnings before interest, taxes, depreciation and amortization, which SunTrust Robinson Humphrey refers to as EBITDA. SunTrust Robinson Humphrey also compared stock price as a multiple of LQA, 2006E and 2007E earnings per share, which SunTrust

Robinson Humphrey refers to as EPS. All multiples were based on closing stock prices as of October 12, 2006. Historical revenues, EBITDA and EPS results were based on financial information available in public filings. Projected revenues, EBITDA and EPS estimates were based on research reports and consensus estimates provided by FactSet Research Systems Inc. or Thomson Financial. FactSet Research Systems Inc. and Thomson Financial are publishers of compilations of information including estimates of projected financial performance for publicly traded companies produced by equity research analysts at investment banking firms. The following table sets forth the median multiples indicated by the market analysis of selected publicly traded reference companies:

		Median of Selected Reference Companies
Firm Value to:
	LQA Revenues	3.1	x
	2006E Revenues	3.2
	2007E Revenues	2.7
	LQA EBITDA	9.8	x
	2006E EBITDA	10.7
	2007E EBITDA	9.2
Price to:
	LQA EPS	20.5	x
	2006E EPS	22.0
	2007E EPS	18.6

Based upon the multiples derived from this analysis, Open Solutions' historical results, which were adjusted, in the fiscal quarter ended March 31, 2006 to reflect Open Solutions' acquisition of BIS LP Inc. (based on information provided in Open Solutions' Current Report on Form 8-K filed with the SEC on June 12, 2006), which SunTrust Robinson Humphrey refers to as pro forma historical results, and estimates of Open Solutions' projected results provided by Open Solutions, SunTrust Robinson Humphrey calculated a range of implied equity values for Open Solutions between $17.23 and $39.79 per share, with an average equity value of $29.14 per share.

SunTrust Robinson Humphrey noted that none of the companies used in the market analysis of selected publicly traded reference companies was identical to Open Solutions and that, accordingly, the analysis necessarily involved complex considerations and judgments concerning differences in financial and operating characteristics of the companies reviewed and other factors that would affect the market values of the selected publicly traded reference companies.

Analysis of Selected Merger and Acquisition Reference Transactions

SunTrust Robinson Humphrey reviewed and analyzed the consideration paid and implied transaction multiples in 22 selected completed and pending mergers and acquisitions in the financial technology sector with acquisition values greater than $75 million announced since February 2004 that SunTrust Robinson Humphrey deemed relevant.

For the selected transactions, SunTrust Robinson Humphrey analyzed, among other things, firm value as a multiple of last twelve months, which SunTrust Robinson Humphrey refers to as LTM, and projected next twelve months, which SunTrust Robinson Humphrey refers to as NTM, revenues and LTM and NTM EBITDA. SunTrust Robinson Humphrey also analyzed equity value as a multiple of LTM and NTM net income. LTM revenues, EBITDA and net income values were based on historical financial information available in public filings or other publicly available information sources. Projected financial information, including NTM revenues, EBITDA and net income, was based on financial information available in public filings or other publicly available information sources, research

reports and consensus estimates provided by FactSet Research Systems Inc. or Thomson Financial. The following table sets forth the multiples indicated by this analysis:

		Median of Reference Transactions
Firm Value to:
	LTM Revenues	3.2	x
	NTM Revenues	2.5
	LTM EBITDA	11.4	x
	NTM EBITDA	9.5
Equity Value to:
	LTM Net Income	25.8	x
	NTM Net Income	23.1

Based upon the multiples derived from this analysis, Open Solutions' pro forma historical results (and in which SunTrust Robinson Humphrey utilized Open Solutions' last quarter annualized performance metrics for developing implied valuation ranges based on LTM metrics), and estimates of Open Solutions' projected results for fiscal 2006 provided by Open Solutions, SunTrust Robinson Humphrey calculated a range of implied equity values for Open Solutions between $21.66 and $37.43 per share, with an average equity value of $27.39 per share.

SunTrust Robinson Humphrey noted that no transaction considered in the analysis of selected merger and acquisition reference transactions is identical to the merger. All multiples for the selected transactions were based on public information available at the time of announcement of such transaction, without taking into account differing market and other conditions during the period during which the selected transactions occurred.

Discounted Cash Flow Analysis

SunTrust Robinson Humphrey performed a discounted cash flow analysis of Open Solutions based upon projections provided by Open Solutions for the fiscal years ending December 31, 2007 through 2010 and projections estimated by SunTrust Robinson Humphrey for the fiscal years ending in 2011 and 2012 based on the foregoing projections and discussions with management to estimate the net present equity value per share of Open Solutions. SunTrust Robinson Humphrey calculated a range of net present firm values for Open Solutions based on its free cash flow (EBITDA less taxes minus capital expenditures and increases in working capital plus decreases in working capital) over the projected time period using a weighted-average cost of capital for Open Solutions ranging between 12% to 14%, based on Open Solutions' weighted-average cost of capital of 12.7% calculated by SunTrust Robinson Humphrey, and terminal value multiples of 2012E EBITDA ranging from 10.0x to 12.0x, based on the foregoing analysis of selected merger and acquisition reference transactions. The analysis indicated the following per share equity valuations of Open Solutions:

	Discounted Present Value of Equity per Share
Discount Rate	Discounted Present Value of Equity per Share
Discount Rate	10.0x		10.7x		11.3x		12.0x
12.0%	$	38.09	$	41.32	$	44.56	$	47.79
12.5%		36.75		39.91		43.07		46.22
13.0%		35.45		38.54		41.62		44.70
13.5%		34.19		37.20		40.21		43.21
14.0%		32.96		35.90		38.83		41.77

Premiums Paid Analysis

SunTrust Robinson Humphrey analyzed the transaction premiums paid in all merger and acquisition transactions of publicly traded companies with equity values between $500 million and $1.5 billion, announced since July 1, 2006, based on the target company's stock price on the day of public announcement and one day, five days and 30 days prior to public announcement of the transaction. Additionally, SunTrust Robinson Humphrey analyzed the transaction premiums paid in all transactions of publicly traded companies in the financial services sector with transaction values between $500 million and $1.5 billion, announced since November 1, 2005, based on the target company's stock price on the day of public announcement and one day, five days and 30 days prior to public announcement of the transaction. This analysis indicated the following premiums paid in the selected transactions:

	Purchase Price Premium
			Prior to Announcement
	Day of Announcement		1 Day		5 Days		30 Days
Average Premium for All Transactions	21.4	%	18.8	%	21.4	%	28.5	%
Average Premium for Transactions in the Financial	21.9	%	22.0	%	21.4	%	26.2	%
Services Sector

Based upon the premiums paid analysis and an announcement date of October 12, 2006, SunTrust Robinson Humphrey calculated a range of implied equity values for Open Solutions between $35.12 and $37.99 per share with an average implied equity value of $36.51 per share.

Other Factors and Analyses

SunTrust Robinson Humphrey took into consideration various other factors and analyses, including historical market prices and trading volumes for Open Solutions' common stock, movements in the common stock of selected publicly traded companies, movements in the S&P 500 Index and the NASDAQ Composite Index and an analysis of the weighted average cost of capital of Open Solutions. In addition, SunTrust Robinson Humphrey analyzed the feasibility, from a financial point of view, of an illustrative leverage buyout transaction involving Open Solutions, as described below, based on theoretical returns that a hypothetical financial sponsor could receive in such a transaction.

Leveraged Buyout Analysis

SunTrust Robinson Humphrey analyzed an illustrative leveraged buyout transaction involving Open Solutions and the theoretical returns that a hypothetical financial sponsor could receive in such a transaction based on a range of purchase prices and the anticipated capital structure of the proposed merger. For purposes of this analysis, SunTrust Robinson Humphrey utilized Open Solutions' pro forma historical results and projected results provided by Open Solutions for the fiscal years ending December 31, 2006 through 2010 and projections estimated by SunTrust Robinson Humphrey for the fiscal year ending 2011 based on the foregoing projections and discussions with management. SunTrust Robinson Humphrey assumed, for purposes of this analysis, a purchase price range of $37.00 to $39.00 per share, which reflects implied entry multiples based on 2006 pro forma EBITDA ranging from 11.6x to 12.1x, and base leverage of 7.3x 2006 pro forma EBITDA. SunTrust Robinson Humphrey also assumed a range of estimated EBITDA exit multiples of 10.0x to 12.0x for the assumed exit year of 2011, which reflect illustrative implied prices at which a hypothetical financial sponsor might exit its Open Solutions investment through a sale transaction. This analysis resulted in illustrative internal rate of equity returns to a hypothetical financial sponsor ranging from 15.1% to 23.6%.

Consideration

Upon the consummation of the merger, each share of Open Solutions common stock issued and outstanding immediately prior to the effective time of the merger (other than shares held in the treasury of the Company, owned by Parent, Merger Co or any directly or indirectly owned subsidiary of the foregoing immediately prior to the effective time of the merger or held by stockholders who are entitled to and who properly exercise and do not timely withdraw demand for appraisal rights with respect to such shares under Delaware Law) will be cancelled and converted into the right to receive $38.00 in cash, without interest and less any applicable withholding taxes. Upon the consummation of the merger, unless otherwise agreed by a holder and Parent, all outstanding options to acquire Open Solutions common stock (whether or not vested) will be cancelled and converted into a right to receive a cash payment equal to the number of shares of Open Solutions common stock underlying the options (whether or not vested) multiplied by the amount (if any) by which $38.00 exceeds the option exercise price, without interest and less applicable withholding taxes. Upon the consummation of the merger, all restricted stock, unless otherwise agreed by a holder and Parent, will be fully vested and will be converted into the right to receive $38.00 in cash, without interest and less any applicable withholding taxes. Upon the consummation of the merger, all restricted stock units, unless otherwise agreed by a holder and Parent, will be cancelled and extinguished and converted into the right to receive a cash payment equal to the number of outstanding restricted stock units multiplied by $38.00 (together with the value of any deemed dividend equivalents accrued but unpaid with respect to the restricted stock units), without interest, less any applicable withholding taxes. However, in lieu of cancellation and cash out, Parent has offered Mr. Hernandez and certain of our executive officers who hold outstanding stock options, restricted stock and/or restricted stock units immediately prior to the completion of the merger the opportunity to exchange, simultaneously with the consummation of the merger, some or all of such outstanding stock options, restricted stock and/or restricted stock units for options to purchase shares of Parent common stock or shares of Parent common stock, as the case may be. This offer is subject to further negotiation and discussion between Parent and the offerees, and no terms or conditions with respect to such offer have been finalized as of the date of this proxy statement.

Delisting and Deregistration of Open Solutions Common Stock; Failure to Consummate the Merger

It is expected that, upon consummation of the merger, the operations of the Company will be conducted substantially as they currently are being conducted except that the Company's common stock will cease to be publicly traded. Following the consummation of the merger, the registration of the Company's common stock and the Company's reporting obligation under the Exchange Act will be terminated upon application to the SEC. In addition, upon consummation of the merger, the Company's common stock will no longer be listed or quoted for trading on any exchange or quotation system, including the NASDAQ National Market, and price quotations will no longer be available. The Company will not be subject to the obligations and constraints, and the related direct and indirect costs and personnel requirements, associated with having publicly traded equity securities. We expect that following the merger, the Company's management and the Sponsors will continuously evaluate and review the Company's business and operations and may develop new plans and proposals that they consider appropriate to maximize the value of the Company, and may undertake any of the foregoing actions if they are deemed desirable at any time following the closing of the merger. The Sponsors expressly reserve the right to make any changes they deem appropriate in light of such evaluation and review or in light of future developments.

If the merger agreement is not adopted by the Company's stockholders or if the merger is not completed for any other reason, stockholders will not receive any payment for their shares in connection with the merger. Instead, the Company will remain an independent public company and the Company's common stock will continue to be listed and traded on the NASDAQ National Market. In addition, if the merger is not completed, we expect that management will operate the business in a manner similar to that in which it is being operated today and that the Company's stockholders will continue to be subject to the same risks and opportunities as they currently are, including, among other things, the nature of the software technologies and services industry on which the Company's business largely depends, and general industry, economic, regulatory and market conditions. Accordingly, if the merger is not consummated, there can be no assurance as to the effect of these risks and opportunities on the future value of your Open Solutions shares. From time to time, the Company's board of directors will evaluate and review, among other things, the business operations, properties, dividend policy and capitalization of the Company and make such changes as are deemed appropriate and continue to seek to identify strategic alternatives to enhance stockholders' value. If the merger agreement is not adopted by the Company's stockholders or if the merger is not consummated for any other reason, there can be no assurance that any other transaction acceptable to the Company will be offered, or that the business, prospects or results of operations of the Company will not be adversely impacted.

In addition, in the limited circumstances described below under "The Merger Agreement—Termination Fees; Expense Reimbursement" where we do not consummate the merger with Merger Co, the Company will be required to pay at the direction of Parent a termination fee of $30 million, or in certain circumstances, to reimburse Parent's out-of-pocket expenses for the transaction of up to $5 million.

Financing

The Company and the Sponsors estimate that the total amount of funds necessary to complete the merger and the related transactions is anticipated to be approximately $1.4 billion, which includes the cash to be paid to the Company's stockholders and holders of other equity-based interests as well as related fees and expenses in connection with the merger, the financing arrangements and the related transactions (including any fees or expenses related to a consent solicitation and/or tender offer in respect of the Company's Senior Subordinated Convertible Notes due 2035). These payments are expected to be funded by a combination of equity contributions by the Sponsors in Parent (or their affiliates) and debt financing, as well as available cash of the Company.

Parent has obtained equity and debt financing commitments for the transactions contemplated by the merger agreement, which are generally subject to customary conditions.

Pursuant to the merger agreement, Parent and Merger Co are obligated to use their reasonable best efforts to obtain the debt financing described below as promptly as practicable taking into account the expected timing of the marketing period and the termination date. In the event that any portion of the debt financing becomes unavailable on the terms contemplated in the agreements in respect thereof, Parent is obligated to use its reasonable best efforts to arrange alternative financing from alternative sources on terms no less favorable to Parent with respect to conditions precedent to the debt financing (as determined in the reasonable judgment of Parent).

Equity Financing

Investment funds affiliated with the Sponsors have committed to contribute an aggregate of $560.0 million in cash directly or indirectly to Merger Co.

Each of the equity commitment letters provides that the equity funds will be contributed at the closing of the merger to fund a portion of the total merger consideration, pursuant to and in accordance with the merger agreement, and related expenses. Each of the equity commitments is generally subject to the satisfaction or waiver by Parent of the conditions to Parent's or Merger Co's obligations to effect the closing under the merger agreement. The Sponsors may assign their commitments to any of their respective affiliates, but any such assignment will not relieve the Sponsor of its obligations under the commitment letter, except to the extent otherwise agreed by Parent. Each of the equity commitment letters will terminate upon the consummation of the merger, upon the termination of the merger agreement, upon the agreement by the Sponsors to terminate the equity commitment letters, or if the Company or its affiliates assert in any litigation or proceeding a claim under an equity commitment letter, the merger agreement or any transaction contemplated thereby. The Company is not a party to, or a beneficiary of, the equity commitment letters, and the Company has no right to seek to enforce any of them.

Following the merger, the entire equity in the surviving corporation will ultimately be owned by the Sponsors and any additional investors (including members of management) that invest with the Sponsors in the transaction. If the merger is completed, the Sponsors and such additional investors that invest in the transaction will be the sole beneficiaries of our future earnings and growth, if any, and will be entitled to vote on corporate matters affecting the Company following the merger. Similarly, the Sponsors and such additional investors that invest in the transaction will also bear the risks of ongoing operations including the risks of any decrease in our value after the merger and the operational and other risks related to the incurrence by the surviving corporation of significant additional debt as described below under "—Financing of the Merger—Debt Financing."

Sponsor Guarantees

In connection with the merger agreement, the Sponsors have agreed to guarantee the due and punctual performance and discharge of certain of the specified payment obligations of Parent and Merger Co under the merger agreement, up to a maximum amount equal to their respective pro rata share of a termination fee of $30 million. Each of the Sponsors' guarantees will generally terminate upon the consummation of the merger or upon the termination of the merger agreement (or, under certain circumstances, upon the first anniversary of any termination of the merger agreement).

We cannot seek specific performance to require Parent and Merger Co to complete the merger, and our exclusive remedy for the failure of Parent and Merger Co to complete the merger and for any other damages or losses incurred by the Company or its affiliates in connection with the merger agreement is the termination fee described above payable to us in the circumstances described under "The Merger Agreement—Termination Fees; Expense Reimbursement."

Debt Financing

Parent and Merger Co have received a debt commitment letter, dated as of November 6, 2006, from Wachovia Bank, National Association ("WBNA"), Wachovia Investment Holdings, LLC ("WIHL"), Wachovia Capital Markets, LLC ("WCML"), JPMorgan Chase Bank, N.A. ("JPMCB"), J.P. Morgan Securities Inc. ("JPMSI"), Merrill Lynch Capital Corporation ("MLCC") and Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPFS," and together with WBNA, WIHL, WCML, JPMCB, JPMSI and MLCC, the "Debt Financing Sources") to provide the following, subject to the conditions set forth therein:

•: to Open Solutions, and, in the case of the revolving credit facility (as described below), to one of its subsidiaries, up to $605 million of senior secured credit facilities; and
•: to Open Solutions, up to $325.0 million under a senior subordinated unsecured bridge facility,

in each case, for the purpose of financing the merger, repaying certain existing indebtedness of Open Solutions and its subsidiaries, paying fees, commissions and expenses incurred in connection with the merger and providing ongoing working capital requirements of the surviving corporation and its subsidiaries

The documentation governing the senior secured credit facilities and the bridge facility has not been finalized and, accordingly, the actual terms of such facilities may differ from those described in this proxy statement.

Conditions Precedent to the Debt Commitments

The availability of the senior secured credit facilities and the bridge facility is subject to, among other things, there not having occurred since October 14, 2006 any change or condition that would constitute a "Company material adverse effect" (see "The Merger Agreement—Representations and Warranties"), consummation of the merger in accordance with the merger agreement (and no provision thereof being waived or amended in a manner materially adverse to the lenders without the consent of the WCML and JPMSI), the completion of the equity commitment funding, the payment of fees and expenses and the negotiation, execution and delivery of definitive documentation.

Senior Secured Credit Facilities

General. The borrower under the senior secured credit facilities will be Open Solutions. A portion of the revolving facility may be borrowed (in Canadian dollars) by a Canadian subsidiary of the surviving corporation on terms and conditions to be agreed.

The senior secured credit facilities will be comprised of a $530.0 million senior secured term loan facility with a term of seven years and a $75.0 million senior secured revolving credit facility with a term of six years. The revolving facility will include sublimits for the issuance of letters of credit and swingline loans. No alternative financing arrangements or alternative financing plans have been made in the event that the senior secured credit facilities are not available as anticipated.

WCML and JPMSI have been appointed as joint lead arrangers and joint bookrunners for the senior secured credit facilities. WBNA will be the sole administrative agent, JPMSI will be the syndication agent and MLPFS will be the documentation agent for the senior secured credit facilities. In addition, additional agents or co-agents for the senior secured credit facilities may be appointed prior to completion of the merger.

Interest Rate and Fees. Loans under the senior secured credit facilities are expected to bear interest, at the borrower's option, at (1) a rate equal to LIBOR (London interbank offer rate) plus an applicable margin, or (2) a rate equal to the higher of (a) the prime commercial lending rate of the administrative agent and (b) the federal funds effective rate plus 0.50%, plus an applicable margin.

After the effective date of the merger, the applicable margins will be subject to reduction only pursuant to a leverage-based pricing grid.

Upon the initial funding of the senior secured credit facilities, Parent has also agreed to pay an underwriting and arrangement fee to the Debt Financing Sources. In addition, the surviving corporation will pay ongoing customary commitment fees (subject to changes based on leverage) and letter of credit fees under the revolving credit facilities.

Prepayments and Amortization. The borrower will be permitted to make voluntary prepayments of the term loans at any time, without premium or penalty (except LIBOR breakage costs). The borrower also will be required to make mandatory prepayments of term loans with (1) net cash proceeds of non-ordinary course asset sales (subject to reinvestment rights), (2) issuances of debt (other than permitted debt) and (3) a percentage of the surviving corporation's excess cash flow (to be defined). The loans under the term facility are expected to be repaid in equal quarterly installments in aggregate annual amounts (with the installments within each such year being equal in amount) for each year following the closing date equal to 1% per annum, with the balance payable at the end of year seven. The term loans may not be reborrowed.

Guarantors. All obligations under the senior secured credit facilities will be fully and unconditionally guaranteed on a joint and several basis by Harpoon Acquisition Corporation and by each existing and future, direct and indirect, wholly-owned restricted material domestic subsidiary of the surviving corporation (and excluding any indirect subsidiaries constituting controlled foreign corporations).

Security. The obligations of the borrower and the guarantors under the senior secured credit facilities will be secured, subject to permitted liens and other agreed upon exceptions, by a first-priority pledges of all the capital stock of the surviving corporation and each of its direct and indirect, material, restricted, domestic subsidiaries and of 65% of the equity interests of the surviving corporation's and any guarantor's "first-tier" foreign subsidiaries, and perfected first priority security interests in an mortgages on substantially all tangible and intangible assets of the surviving corporation and the guarantors. If the security (other than any domestic stock pledge and any security interest capable of perfection by the filing of a Uniform Commercial Code financing statement) is not provided at closing despite the use of commercially reasonable efforts to do so, the delivery of the security will not be a condition precedent to the availability of the senior secured credit facilities on the closing date, but instead will be required to be delivered following the closing date.

Other Terms. The senior secured credit facilities will contain customary representations and warranties and customary affirmative and negative covenants, including, among other things, restrictions on indebtedness, investments, sales of assets, mergers and consolidations, prepayments of subordinated indebtedness and certain other indebtedness, liens, transactions with affiliates, and dividends and other distributions. The senior secured facilities will also include customary events of default, including a change of control.

Senior Subordinated Notes

Open Solutions is expected to issue up to $325.0 million aggregate principal amount of senior subordinated notes. The notes will not be registered under the Securities Act of 1933, as amended, or Securities Act, and may not be offered in the United States absent registration under, or an applicable exemption from the registration requirements of, the Securities Act. Open Solutions is expected to offer the notes to "qualified institutional buyers" pursuant to Rule 144A under the Securities Act and to other purchasers pursuant to other applicable exemptions under the Securities Act.

Bridge Facility

If the offering of senior subordinated notes by Open Solutions is not completed on or prior to the closing of the merger, the Debt Financing Sources have committed to provide up to $325.0 million in loans under a senior subordinated unsecured bridge facility to the surviving corporation. After consummation of the merger, the surviving corporation will be the borrower under the bridge facility. The obligations of the borrower and the guarantors under the bridge facility will be guaranteed by each subsidiary of the surviving corporation which is a guarantor of the senior secured credit facilities provided that the obligations of the borrower and the guarantors under the bridge facility will be guaranteed on a senior subordinated unsecured basis.

If the bridge loan is not paid in full on or before the date that is twelve months after the initial funding, the maturity of the bridge loan will (with some exceptions) be automatically extended to the date that is the eight years after the initial funding. Holders of the outstanding bridge loan may choose to exchange such loans for unsecured senior subordinated exchange notes that the surviving corporation would be required to register for public sale under a registration statement in compliance with applicable securities laws. The maturity of the exchange notes will mature on the date that is eight years after the initial funding.

WCML and JPMSI have been appointed as joint lead arrangers and joint bookrunners for the bridge facility. WIHL or one of its affiliates will act as the sole administrative agent for the bridge facility. In addition, additional agents or co-agents for the bridge facility may be appointed prior to completion of the merger.

Interests of the Company's Directors and Executive Officers in the Merger

In considering the recommendation of the Company's board of directors with respect to the merger, you should be aware that some of the Company's directors and executive officers have interests in the merger that are different from, or in addition to, the interests of our stockholders generally. These interests may present them with actual or potential conflicts of interest, and these interests, to the extent material, are described below. The Company's board of directors and the special committee was aware of these interests and considered them, among other matters, in approving the merger and the merger agreement and recommending that our stockholders vote in favor of adopting the merger agreement.

Treatment of Stock Options

As of the record date, there were approximately shares of our common stock subject to stock options granted under our equity incentive plans to our current executive officers and directors. Except as otherwise described below, each outstanding stock option that remains unexercised as of the completion of the merger, whether or not the option is vested or exercisable, will be canceled, and the holder of such stock option will be entitled to receive a cash payment, without interest and less applicable withholding taxes, equal to the product of:

•: the number of shares of our common stock subject to the option as of the effective time of the merger, multiplied by
•: the excess, if any, of $38.00 over the exercise price per share of common stock subject to such option.

However, in lieu of cancellation and cash out, Parent has offered Mr. Hernandez and certain of our executive officers who hold outstanding stock options immediately prior to the completion of the merger the opportunity to exchange, simultaneously with the consummation of the merger, some or all of such outstanding stock options for options to purchase shares of Parent common stock. This offer is

subject to further negotiation and discussion between Parent and the offerees, and no terms or conditions with respect to such offer have been finalized as of the date of this proxy statement.

The following table summarizes the vested and unvested options with exercise prices of less than $38.00 per share held by our executive officers and directors as of October 31, 2006 and the consideration that each of them will receive pursuant to the merger agreement in connection with the cancellation of their options (assuming no conversion of options occurs):

	Unvested Options	Weighted Average Exercise Price of Unvested Options		Vested Options	Weighted Average Exercise Price of Vested Options		Resulting Consideration(1)

(2): Mr. Hernandez also serves as the Chairman and chief executive officer of the Company.

Treatment of Restricted Stock and Restricted Stock Units

As of the record date, there were approximately shares of our common stock represented by restricted stock and restricted stock units held by our directors and executive officers under our equity incentive plans. Under the terms of the merger agreement, all such restricted stock and restricted stock units shall become immediately vested and free of restrictions effective as of the completion of the merger. At the effective time of the merger, except as described below, any such equity award that is then outstanding will be canceled, and the holder of each such equity award will receive a cash payment of $38.00 (together, in the case of restricted stock units, with the value of any deemed dividend equivalents accrued but unpaid with respect to the restricted stock units) per underlying unit, without interest and less any applicable withholding taxes.

However, in lieu of cancellation and cash out, Parent has offered Mr. Hernandez and certain of our executive officers who hold restricted stock and/or restricted stock units immediately prior to the completion of the merger the opportunity to exchange, simultaneously with the consummation of the merger, some or all of such restricted stock and/or restricted stock units for shares of Parent common stock. This offer is subject to further negotiation and discussion between Parent and the offerees, and no terms or conditions with respect to such offer have been finalized as of the date of this proxy statement.

The following table summarizes the restricted stock and restricted stock units held by our directors and executive officers as of September 30, 2006 and the consideration that each of them will receive pursuant to the merger agreement in connection with the cancellation of such awards:

Severance Agreements/Change of Control

Our non-employee directors and executive officers (other than our chief executive officer) are participants in change in control protection plans pursuant to which any stock options, restricted stock units and restricted stock awards previously granted to non-employee directors will become fully vested upon a change in control (as defined in such plans). In addition, in the event that such an executive officer is terminated without cause (as defined in the plans) or for good reason (as defined in the plans) within two years after a change in control, the executive officer will be entitled to (x) continuation of benefits for 12 months after the termination date, (y) a lump sum payment equal to the executive officer's (i) base salary in effect on the date of termination plus (ii) target bonus for the year of termination plus (iii) prorated annual bonus for the year of termination, and (z) full acceleration of any stock options and restricted stock awards previously granted to the executive officer.

The Company and Mr. Hernandez entered into a three year Employment Agreement (the "Employment Agreement") dated as of April 21, 2005, and amended February 17, 2006, pursuant to which the Company agreed to pay Mr. Hernandez an annual base salary of $400,000, subject to increase at the discretion of the board of directors, for his services as chief executive officer of the Company. Effective April 1, 2006, Mr. Hernandez's annual base salary was increased to $475,000. The Employment Agreement also provides for Mr. Hernandez to receive an annual cash bonus based on the achievement of certain performance targets, with a target payment of 75% of his base salary and a maximum payment of 150% of his base salary. The Company also pays an annual life insurance premium and a monthly car allowance for Mr. Hernandez, and reimburses him for individual financial planning and tax preparation services. Mr. Hernandez has agreed not to compete with the Company's business or to solicit any of the Company's employees or clients during the 12-month period following the termination of his employment. If Mr. Hernandez's employment is terminated without cause or

with good reason (each, as defined in the Employment Agreement), he will receive a payment equal to the full amount of his target bonus for the year of termination, will continue to receive his base salary and benefits for one year after termination and is entitled to the continuation of his other benefits described in the Employment Agreement for 12 months (e.g. premium payments for life insurance, provision of a car or cash car allowance and payment for tax-related services). If Mr. Hernandez's employment is terminated upon a change of control (as defined in the Employment Agreement), he will receive a payment on the date of his termination equal to two times the sum of his base salary at the time and his target bonus for the year of termination. Upon his termination following a change of control, Mr. Hernandez will also continue to receive benefits for two years and any outstanding stock options and restricted stock held by him will become fully vested.

The merger would constitute a change of control for purposes of the Employment Agreement.

The Company currently anticipates paying transaction bonuses of up to $1 million, in the aggregate, to certain executive officers and other members of senior management of the Company in connection with the merger. No other terms or conditions with respect to such bonuses, including the names of the recipients and the individual amounts, have been finalized as of the date of this proxy statement.

Indemnification and Insurance

The merger agreement provides that the surviving corporation will indemnify and advance expenses to each present and former director or officer of the Company or any of our subsidiaries, in and to the extent of their capacities as such and not as stockholders of the Company or any of its subsidiaries, in respect of actions, omissions or events through the effective time of the merger to the fullest extent permitted by applicable law and any indemnity agreements applicable to such indemnified party in effect on the date of the merger agreement. Without limiting the generality of the preceding sentence, if any indemnified party becomes involved in any actual or threatened action, suit, claim, proceeding or investigation covered by the preceding sentence after the effective time of the merger, the surviving corporation will, to the fullest extent permitted by applicable law, promptly advance to such indemnified party his or her legal or other expenses (including the cost of any investigation and preparation incurred in connection therewith).

The merger agreement provides that the surviving corporation will (i) maintain in effect for a period of six years after the effective time of the merger, if available, the current directors' and officers' liability insurance policies maintained by the Company immediately prior to the effective time of the merger (provided that the surviving corporation may substitute therefor policies of at least the same coverage containing terms and conditions that are not less favorable to the directors and officers of the Company) or (ii) obtain as of the effective time of the merger "tail" insurance policies with a claims period of at least six years from the effective time of the merger with respect to directors' and officers' liability insurance in amount and scope, and with other material terms and conditions, at least as favorable as the Company's existing policies for claims arising from facts or events that occurred prior to the effective time of the merger; provided, however that in the event the surviving corporation would otherwise be required to expend an annual premium for such coverage in excess of 300% of the last annual premium paid by the Company for such insurance prior to the date of the merger agreement, we will obtain as much coverage as can be obtained for the remainder of such period for a premium not in excess of 300% of such annual premium.

The merger agreement provides that for a period of six years after the effective time of the merger, the surviving corporation and each of its subsidiaries shall include and maintain in effect in their respective certificates of incorporation or bylaws (or similar organizational document), provisions regarding the indemnification of and advancement of expenses of officers and directors thereof that are no less favorable than the corresponding provisions contained in such organizational documents as of the date of the merger agreement.

New Management Arrangements

As of the date of this proxy statement, neither we nor the Sponsors have entered into any employment agreements with our management in connection with the merger, nor have we amended or modified any existing employment agreements. The Sponsors have informed us that they currently intend to retain members of our management team following the merger, and that they anticipate that Louis Hernandez, our chief executive officer, will continue as chief executive officer. It is further contemplated that the other executive officers of the Company immediately prior to the effective time of the merger will be the initial officers of the surviving corporation. Mr. Hernandez, on behalf of himself and other members of management, is currently in discussions with the Sponsors regarding terms of employment following the merger. Parent has offered Mr. Hernandez and certain of our executive officers who hold outstanding stock options, restricted stock and/or restricted stock units immediately prior to the completion of the merger the opportunity to exchange, simultaneously with the consummation of the merger, some or all of such outstanding stock options, restricted stock and/or restricted stock units (in lieu of the cash out and cancellation described under "Interests of the Company's Directors and Executive Officers in the Merger—Treatment of Stock Options" and "Interests of the Company's Directors and Executive Officers in the Merger—Treatment of Restricted Stock and Restricted Stock Units") for options to purchase shares of Parent common stock or shares of Parent common stock, as the case may be. This offer is subject to further negotiation and discussion between Parent and the offerees, and no terms or conditions with respect to such offer have been finalized as of the date of this proxy statement. It is not anticipated that this offer would result in our executive officers acquiring more than approximately 3.5% of the fully-diluted equity of Parent.

Further, although no agreements have been entered into as of the date of this proxy statement, Parent expects in connection with the merger to adopt an option plan under which certain employees (including certain officers and key employees), directors and/or consultants will be eligible to receive awards of options to purchase shares of Parent common stock. The aggregate number of shares issuable pursuant to grants under that plan are expected to be approximately 15% of the fully-diluted equity of Parent, a majority of which is likely to be allocated to our executive officers. It is expected that a substantial portion of such options would vest based on meeting specified performance goals and the remainder would vest based on continued service with the surviving corporation over a specified period.

Although it is likely that certain members of our management team will enter into new arrangements with Parent regarding employment (and severance arrangements) with, and the right to purchase or participate in the equity of, Parent, as described above, there can be no assurance that the parties will reach agreement. These matters are subject to further negotiations and discussion and no terms or conditions have been finalized. Any new arrangements are currently expected to be entered into at or prior to the completion of the merger. In addition, it is anticipated that one or more members of management, including Mr. Hernandez, will serve on the governing board of Parent. The Company's board of directors (without management's participation) previously authorized reimbursement of management's reasonable out-of-pocket legal expenses in connection with negotiating management's arrangements with Parent.

Material United States Federal Income Tax Consequences

The following is a general discussion of certain material U.S. federal income tax consequences of the merger to holders of our common stock whose shares are converted into the right to receive cash in the merger (whether upon receipt of the merger consideration or pursuant to the proper exercise of appraisal rights). We base this summary on the provisions of the Code, applicable current and proposed U.S. Treasury Regulations, judicial authority, and administrative rulings and practice, all of which are subject to change, possibly on a retroactive basis.

For purposes of this discussion, we use the term "U.S. holder" to mean a beneficial owner of common stock that is:

•: a citizen or individual resident of the U.S. for U.S. federal income tax purposes;
•: a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the U.S. or any state or the District of Columbia;
•: a trust if it (1) is subject to the primary supervision of a court within the U.S. and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person; or
•: an estate the income of which is subject to U.S. federal income tax regardless of its source.

A "non-U.S. holder" is a person (other than a partnership) that is not a U.S. holder.

This discussion assumes that a holder holds the shares of our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income tax that may be relevant to a holder in light of its particular circumstances, or that may apply to a holder that is subject to special treatment under the U.S. federal income tax laws (including, for example, insurance companies, dealers in securities or foreign currencies, traders in securities who elect the mark-to-market method of accounting for their securities, stockholders subject to the alternative minimum tax, persons that have a functional currency other than the U.S. dollar, tax-exempt organizations, financial institutions, mutual funds, partnerships or other pass through entities for U.S. federal income tax purposes, controlled foreign corporations, passive foreign investment companies, certain expatriates, corporations that accumulate earnings to avoid U.S. federal income tax, stockholders who hold shares of our common stock as part of a hedge, straddle, constructive sale or conversion transaction, stockholders who will hold, directly or indirectly, an equity interest in the surviving corporation or stockholders who acquired their shares of our common stock through the exercise of employee stock options or other compensation arrangements). In addition, the discussion does not address any tax considerations under state, local or foreign laws or U.S. federal laws other than those pertaining to the U.S. federal income tax that may apply to holders. Holders are urged to consult their own tax advisors to determine the particular tax consequences, including the application and effect of any state, local or foreign income and other tax laws, of the receipt of cash in exchange for our common stock pursuant to the merger.

If a partnership holds our common stock, the tax treatment of a partner will generally depend on the status of the partners and the activities of the partnership. If you are a partner of a partnership holding our common stock, you should consult your tax advisor.

U.S. Holders

The receipt of cash in the merger (or pursuant to the exercise of dissenters' rights) by U.S. holders of our common stock will be a taxable transaction for U.S. federal income tax purposes. In general, for U.S. federal income tax purposes, a U.S. holder of our common stock will recognize gain or loss equal to the difference between:

•: the amount of cash received in exchange for such common stock determined before the deduction of any applicable withholding taxes; and
•: the U.S. holder's adjusted tax basis in such common stock.

If the holding period in our common stock surrendered in the merger (or pursuant to the exercise of dissenters' rights) is greater than one year as of the date of the merger, the gain or loss will be

long-term capital gain or loss. Long term capital gains of non-corporate holders, including individuals, are eligible for reduced rates of taxation. The deductibility of a capital loss recognized on the exchange is subject to limitations under the Code. If a U.S. holder acquired different blocks of our common stock at different times and different prices, such holder must determine its adjusted tax basis and holding period separately with respect to each block of our common stock.

Under the Code, a U.S. holder of our common stock may be subject, under certain circumstances, to information reporting on the cash received in the merger (or pursuant to the exercise of dissenters' rights) unless such U.S. holder is a corporation or other exempt recipient. Backup withholding will also apply (currently at a rate of 28%) with respect to the amount of cash received, unless a U.S. holder provides proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be refunded or credited against a U.S. holder's U.S. federal income tax liability, if any, provided that such U.S. holder furnishes the required information to the Internal Revenue Service in a timely manner.

Non-U.S. Holders

Any gain realized on the receipt of cash in the merger (or pursuant to the exercise of dissenters' rights) by a non-U.S. holder generally will not be subject to United States federal income tax unless:

•: the gain is effectively connected with a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the non-U.S. holder);
•: the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or
•: we are or have been a "United States real property holding corporation" for U.S. federal income tax purposes and the non-U.S. holder owned more than 5% of the Company's common stock at any time during the five years preceding the merger.

An individual non-U.S. holder described in the first bullet point immediately above will be subject to tax on the net gain derived from the merger under regular graduated U.S. federal income tax rates. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the merger, which may be offset by U.S. source capital losses, even though the individual is not considered a resident of the United States. If a non-U.S. holder that is a foreign corporation falls under the first bullet point immediately above, it will be subject to tax on its net gain in the same manner as if it were a United States person as defined under the Code and, in addition, may be subject to the branch profits tax equal to 30% of its effectively connected earnings and profits or at such lower rate as may be specified by an applicable income tax treaty.

We believe we are not, have not been and do not anticipate becoming a "United States real property holding corporation" for U.S. federal income tax purposes.

Information reporting and, depending on the circumstances, backup withholding (currently at a rate of 28%) will apply to the cash received in the merger (or pursuant to the exercise of dissenters' rights), unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code) or such owner otherwise establishes an exemption. Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be refunded or credited against a non-U.S. holder's U.S. federal income tax liability, if any, provided that such non-U.S. holder furnishes the required information to the Internal Revenue Service in a timely manner.

Regulatory Approvals

Under the Hart-Scott-Rodino Act and the rules and regulations promulgated thereunder, the merger may not be completed until the expiration of a 30-day waiting period following the filing of notification and report forms with the Federal Trade Commission (which we refer to as the FTC) and the Antitrust Division of the U.S. Department of Justice (which we refer to as the Antitrust Division) by the Company and Parent, unless a request for additional information and documentary material is received from the FTC or the Antitrust Division or unless early termination of the waiting period is granted. If, within the initial 30-day waiting period, either the FTC or the Antitrust Division issues a request for additional information and documentary material concerning the merger, then the waiting period will be extended until the 30th calendar day after the date of substantial compliance with the request by all parties, unless earlier terminated by the FTC or the Antitrust Division or further extended by court order or with the parties' consent. The parties filed their respective notification and report forms with the FTC and the Antitrust Division under the Hart-Scott-Rodino Act on October 30, 2006 and were granted early termination of the Hart-Scott-Rodino Act waiting period on November 14, 2006.

The Company also derives revenues in certain other jurisdictions, primarily Canada, where regulatory filings or approvals may be required or advisable in connection with the completion of the merger. We are currently in the process of reviewing where such filings or approvals may be required or desirable, and we will make filings in such jurisdictions if we determine doing so is required or desirable.

While we believe that we will receive the requisite approvals and clearances for the merger, there can be no assurance that a challenge to the merger on antitrust grounds will not be made or, if a challenge is made, of the result of such challenge. Similarly, there can be no assurance that the parties will obtain the regulatory approvals necessary to complete the merger or that the granting of these approvals will not involve the imposition of conditions to the completion of the merger or require changes to the terms of the merger. These conditions or changes could result in the conditions to the merger not being satisfied prior to the termination date or at all. Under the merger agreement, the Company and Parent have agreed to use their reasonable best efforts to obtain all required governmental approvals in connection with the execution of the merger agreement and completion of the merger.

Litigation

On October 16, 2006, a purported class action complaint, Levy Investments, Ltd. v. Open Solutions Inc. et al. (CA No. 2479-N), was filed in the Court of Chancery of the State of Delaware in New Castle County by a putative stockholder of the Company against the Company, its directors and the Sponsors challenging the merger. The complaint alleges that the Company and each of its directors breached their fiduciary duties to the stockholders in connection with the proposed merger, and that The Carlyle Group and Providence Equity Partners Inc. aided and abetted the individual defendants' breach. The complaint seeks, among other things, injunctive relief to enjoin the consummation of the merger, that defendants account to plaintiffs and other members of the class for all damages caused to them and all profits and other special benefits allegedly received as a result of the alleged breach of fiduciary duties, and reasonable attorney's fees and expenses.

This lawsuit is in its preliminary stage. The Company and the members of its board of directors believe that the lawsuit is without merit and intend to defend vigorously against it.

THE MERGER AGREEMENT

This section of the proxy statement describes the material provisions of the merger agreement but does not purport to describe all of the terms of the merger agreement. The following summary is qualified in its entirety by reference to the complete text of the merger agreement, which is attached as Annex A to this proxy statement and incorporated into this proxy statement by reference. We urge you to read the full text of the merger agreement because it is the legal document that governs the merger. It is not intended to provide you with any other factual information about us. Such factual information can be found elsewhere in this proxy statement and in the public filings we make with the SEC, as described in the section entitled "Where You Can Find Additional Information" below.

The Merger

The merger agreement provides for the merger of Merger Co with and into the Company upon the terms, and subject to the conditions, of the merger agreement. The merger will be effective at the time the certificate of merger is filed with the Secretary of State of the State of Delaware (or at a later time, if agreed upon by the parties and specified in the certificate of merger). We expect to complete the merger as promptly as practicable after our stockholders adopt the merger agreement and, if necessary, the expiration of the marketing period described below (plus five calendar days).

As the surviving corporation, Open Solutions will continue to exist following the merger. At the effective time of the merger, the Company's certificate of incorporation will be amended to read in its entirety as set forth in Exhibit A to the merger agreement. The Company's bylaws will be amended in their entirety to be the same as the bylaws of Merger Co immediately prior to the effective time of the merger, except that the name of the surviving corporation will be "Open Solutions Inc." Upon consummation of the merger, the directors of Merger Co will be the initial directors of the surviving corporation and the officers of Open Solutions will be the initial officers of the surviving corporation. All surviving corporation officers will hold their positions until their successors are duly elected and qualified or until the earlier of their resignation or removal.

We, Parent or Merger Co may terminate the merger agreement prior to the consummation of the merger in some circumstances, whether before or after the approval of the merger agreement by stockholders. Additional details on termination of the merger agreement are described in "—Termination of the Merger Agreement."

Merger Consideration

Each share of Open Solutions common stock issued and outstanding immediately before the merger will automatically be cancelled and will cease to exist and will be converted into the right to receive $38.00 in cash, without interest and less any applicable withholding taxes, other than:

•: shares held in treasury or owned by Parent, Merger Co or any direct or indirect wholly-owned subsidiary of Parent, Merger Co or the Company, that will be cancelled without conversion or payment, and
•: shares held by holders who have properly demanded and perfected and have not timely withdrawn demand for their appraisal rights with respect to such shares.

After the merger is effective, each holder of a certificate representing any shares of Open Solutions common stock (other than shares for which appraisal rights have been properly demanded and perfected) will no longer have any rights with respect to the shares, except for the right to receive the merger consideration. See "Dissenters' Rights of Appraisal."

Treatment of Options and Other Awards

Upon the consummation of the merger, except as otherwise agreed by the holder and Parent, all outstanding options to acquire Open Solutions common stock granted under the Company's equity incentive plans will (whether or not vested) be cancelled and converted into the right to receive a cash payment equal to the number of shares of Open Solutions Common Stock underlying the option multiplied by the amount by which $38.00 exceeds the exercise price for each share of Open Solutions common stock underlying the options (whether or not vested), without interest and less any applicable withholding taxes. Additionally, all shares of restricted stock and restricted stock units will, upon the consummation of the merger, except as otherwise agreed by the holder and Parent, vest and be cancelled and converted into the right to receive a cash payment equal to the number of outstanding restricted stock and restricted stock units multiplied by $38.00 (together, in the case of restricted stock units, with the value of any deemed dividend equivalents accrued but unpaid with respect to such restricted stock units), without interest and less any applicable withholding taxes.

However, Parent has offered Mr. Hernandez and certain of our executive officers who hold outstanding stock options, restricted stock and/or restricted stock units immediately prior to the completion of the merger the opportunity to exchange, simultaneously with the consummation of the merger, some or all of such outstanding stock options, restricted stock and/or restricted stock units for options (in lieu of the cash out and cancellation described above) to purchase shares of Parent common stock or shares of Parent common stock, as the case may be. This offer is subject to further negotiation and discussion between Parent and the offerees, and no terms or conditions with respect to such offer have been finalized as of the date of this proxy statement.

The effect of the merger upon our employee stock purchase plan is described below under "—Employee Benefits."

Payment for the Shares

Before the merger, we will designate a paying agent reasonably satisfactory to Parent (which, with respect to options and restricted stock units, may be the Company's payroll agent) to make payment of the merger consideration as described above. At the effective time of the merger, the surviving corporation will deposit, or Parent shall cause the surviving corporation to deposit, in trust with the paying agent the funds appropriate to pay the merger consideration to the equity holders entitled to receive such consideration.

Upon the consummation of the merger and the settlement of transfers that occurred prior to the effective time, we will close our stock ledger. After that time, there will be no further transfer of shares of Open Solutions common stock.

As promptly as practicable, but in any event within four business days, after the consummation of the merger, the surviving corporation will cause the paying agent to send you a letter of transmittal and instructions advising you how to surrender your certificates in exchange for the merger consideration. The paying agent will pay you your merger consideration after you have (1) surrendered your certificates to the paying agent and (2) provided to the paying agent your duly completed and signed letter of transmittal and any other items specified by the letter of transmittal. Interest will not be paid or accrue in respect of the merger consideration. The surviving corporation will reduce the amount of any merger consideration paid to you by any applicable withholding taxes. YOU SHOULD NOT FORWARD YOUR STOCK CERTIFICATES TO THE PAYING AGENT WITHOUT A LETTER OF TRANSMITTAL, AND YOU SHOULD NOT RETURN YOUR STOCK CERTIFICATES WITH THE ENCLOSED PROXY.

If any cash deposited with the paying agent is not claimed within one year following the effective time of the merger, such cash will be returned to the surviving corporation upon demand, and any

holders of Shares who have not complied with the exchange procedures thereafter may look only to the surviving corporation for payment of their claim for the merger consideration. Any unclaimed amounts remaining immediately prior to when such amounts would escheat to or become property of any governmental authority will, to the extent permitted by applicable law, be returned to the surviving corporation free and clear of any prior claims or interest thereto.

If the paying agent is to pay some or all of your merger consideration to a person other than you, as the registered owner of a stock certificate, you must have your certificates properly endorsed or otherwise in proper form for transfer, and you must pay any transfer or other taxes payable by reason of the transfer or establish to the surviving corporation's reasonable satisfaction that the taxes have been paid or are not required to be paid.

The transmittal instructions will tell you what to do if you have lost your certificate, or if it has been stolen or destroyed. You will have to provide an affidavit to that fact and, if required by the paying agent or surviving corporation, post a bond in an amount that the surviving corporation or the paying agent reasonably directs as indemnity against any claim that may be made against the surviving corporation in respect of the certificate.

Representations and Warranties

The merger agreement contains representations and warranties made by us to Parent and Merger Co and representations and warranties made by Parent and Merger Co to us. The assertions embodied in those representations and warranties were made solely for purposes of the merger agreement and may be subject to important qualifications and limitations agreed by the parties in connection with negotiating its terms. Moreover, some of those representations and warranties may not be accurate or complete as of any particular date because they are subject to a contractual standard of materiality or material adverse effect different from that generally applicable to public disclosures to stockholders or used for the purpose of allocating risk between the parties to the merger agreement rather than establishing matters of fact. For the foregoing reasons, you should not rely on the representations and warranties contained in the merger agreement as statements of factual information.

In the merger agreement, the Company, Parent and Merger Co each made representations and warranties relating to, among other things:

•: corporate organization and existence;
•: certificate of incorporation and bylaws (or similar organizational documents);
•: corporate power and authority to enter into and perform its obligations under, and enforceability of, the merger agreement;
•: required regulatory filings and consents and approvals of governmental entities;
•: the absence of conflicts with or defaults under organizational documents, other contracts and applicable laws and judgments;
•: absence of litigation;
•: finder's fees; and
•: information supplied for inclusion in this proxy statement.

In the merger agreement, Parent and Merger Co also each made representations and warranties relating to the availability of the funds necessary to perform its obligations under the merger agreement and to pay all related fees and expenses associated therewith, including payment of the merger consideration, guarantees and operations of Parent and Merger Co.

The Company also made representations and warranties relating to, among other things:

•: capital structure;
•: documents filed with the SEC;
•: undisclosed liabilities;
•: compliance with applicable laws;
•: agreements with affiliates;
•: absence of certain changes or events since December 31, 2005;
•: compliance with the Employee Retirement Income Securities Act of 1974, as amended, and other employee benefit matters;
•: real estate matters;
•: intellectual property matters;
•: tax matters;
•: environmental matters;
•: material contracts;
•: insurance matters;
•: board and stockholder approval of the merger agreement and related transactions;
•: anti-takeover statutes; and
•: fairness opinion of SunTrust Robinson Humphrey.

Many of the Company's representations and warranties are qualified by a material adverse effect standard. For purposes of the merger agreement, a "Company material adverse effect" is defined to mean any event, circumstance, development, change or effect that is, individually or in the aggregate, materially adverse to the business, financial condition, assets or results of operations of the Company and its subsidiaries, taken as a whole, other than (i) any failure to meet internal or published projections, forecasts or revenue or earning predictions for any period (provided that the underlying causes of such failure shall be considered in determining whether there is a Company material adverse effect) and (ii) any change, circumstance, event or effect resulting from any of the following:

(A): changes in general economic or political conditions or the securities, credit or financial markets in general;
(B): general changes or developments in the industries in which the Company and its subsidiaries operate, including general changes in law or regulation across such industries;
(C): any acts of terrorism or war (other than to the extent that any of the foregoing causes any damage or destruction to, or renders unusable, any facility or property of the Company or any of its subsidiaries);
(D): the announcement of the execution of the merger agreement or the pendency of consummation of the merger; and
(E): changes in generally accepted accounting principles or the interpretation thereof;

except, in the case of the foregoing clauses (A), (B) and (C), to the extent such changes or developments referred to therein would reasonably be expected to have a materially disproportionate impact on the Company and its subsidiaries, taken as a whole.

Conduct of Business Pending the Merger

We have agreed in the merger agreement that, until the consummation of the merger, except as expressly consented to in writing by Parent (which consent shall not be unreasonably withheld or delayed), the business of the Company and its subsidiaries will be conducted in the ordinary course of business consistent with past practice. In addition, the Company will, and will cause each of its subsidiaries to, use reasonable best efforts consistent with past practice to preserve substantially intact the business organization of the Company and its subsidiaries, to keep available the services of our present officers and key employees and to maintain the current relationships of the Company and its subsidiaries with customers, suppliers and others with which the Company or any of its subsidiaries has material business relationships.

The Company has also agreed that, until the consummation of the merger, except as expressly contemplated or permitted by the merger agreement or consented to in writing by Parent and Merger Co (which consent will not be unreasonably withheld or delayed), the Company will not, and will not permit any of its subsidiaries to:

•: amend or otherwise change its certificate of incorporation or bylaws;
•: issue, deliver, sell, transfer, dispose of, pledge or encumber any shares of its capital stock or equity interests, any other voting securities or any securities convertible into, or any rights, warrants or options to acquire, any such shares of capital stock or equity interests, voting securities or convertible securities, other than in connection with (i) certain grants to employees, consultants and directors of the Company or its subsidiaries, in the ordinary course of business, of stock options not to exceed 250,000 options and shares of restricted stock not to exceed 100,000 shares in the aggregate, (ii) the exercise of stock options outstanding on the date of the merger agreement, (iii) the vesting of restricted stock units outstanding on the date of the merger agreement, (iv) the exercise of rights to purchase shares of common stock outstanding under the Company's Employee Stock Purchase Plan as of the date of the merger agreement or (v) the conversion of the Convertible Notes;
•: declare, set aside, make or pay any dividend or other distribution, payable in cash, stock, property or otherwise, with respect to any of its capital stock or equity interests, except for dividends by any direct or indirect wholly-owned subsidiary to the Company or any other wholly-owned subsidiary;
•: other than in the case of wholly-owned subsidiaries and other than cashless exercises of stock options or the withholding of restricted stock units in accordance with their terms, reclassify, combine, split, subdivide or redeem, or purchase or otherwise acquire, directly or indirectly, any capital stock or equity interests of the Company or any of its subsidiaries;
•: acquire (including by merger, consolidation, or acquisition of stock or assets or any other business combination) any corporation, partnership, other business or business organization or any division or business unit thereof;
•: incur, guarantee, modify, repurchase, prepay or redeem any indebtedness other than in connection with repayments with respect to the Company's existing credit facilities;
•: in 2006, authorize, make or make any commitment with respect to, any single capital expenditure which is in excess of $750,000 or capital expenditures which are, in the aggregate, in excess of $10,000,000, and in any fiscal quarter of 2007, authorize, make or make any commitment with respect to, capital expenditures which are, in the aggregate, in excess of $12,000,000;
•: enter into any new line of business;
•: other than in the ordinary course of business or pursuant to contracts existing as of the date of the merger agreement providing for advances to Company employees, make any loans,

advances or capital contributions to, or investments in, persons other than wholly-owned subsidiaries of the Company;

•

other than in the ordinary course of business and consistent with past practice, sell, lease, license, encumber or otherwise dispose of (by merger, consolidation, sale of stock or assets or otherwise) any of its material assets;

•

adopt or enter into a plan of complete or partial liquidation, dissolution, restructuring, recapitalization or other reorganization of the Company or any of its subsidiaries (other than the merger);

•

take certain actions with respect to compensation and employee benefits, including:

•: increase the salary, wages, benefits, bonuses or other compensation payable or to become payable to its current or former directors or officers, except for increases required under employment agreements existing on the date of the merger agreement and disclosed to Parent;
•: materially increase the salary, wages, benefits, bonuses or other compensation payable or to become payable to its current or former employees, except for increases required under employment agreements existing on the date of the merger agreement;
•: enter into any employment, change of control or severance agreement with, or establish, adopt, enter into or materially amend any benefits plan, bonus, profit sharing, thrift, stock option, restricted stock, pension, retirement, welfare, deferred compensation, employment, change of control, termination, severance or other benefit plan, agreement, policy or arrangement for the benefit of, any current or former director, officer or employee;
•: accelerate the payment of any compensation or benefit under the Company's employee benefits plans;
•: grant any new awards under the Company's employee benefits plans, including stock plans;

except, in each case, in the ordinary course of business, consistent with past practices with respect to employees that are not officers or directors, or as may be required by the terms of any such plan, agreement, policy or arrangement in effect on the date of the merger agreement or as may be required by applicable law;

•: other than in the ordinary course of business consistent with past practice or except to the extent required by law, make or change any material tax election, settle or compromise any material tax liability of the Company or any of its subsidiaries, agree to an extension of the statute of limitations with respect to the assessment or determination of material taxes of the Company or any of its subsidiaries, file any amended tax return with respect to any material tax, enter into any closing agreement with respect to any material tax or surrender any right to claim a material tax refund;
•: make any change in financial accounting methods or method of income tax accounting, principles or practices materially affecting the reported consolidated assets, liabilities or results of operations of the Company and its subsidiaries, except insofar as may have been required by a change in U.S. generally accepted accounting principles, or GAAP, or law;

•: enter into, renew or amend in any material respect any transaction, agreement, arrangement or understanding between (i) the Company or any of its subsidiaries, on the one hand, and (ii) any affiliate of the Company (other than any of the Company's subsidiaries), on the other hand, of the type that would be required to be disclosed under Item 404 of Regulation S-K;
•: (i) assign, transfer, license or sublicense, mortgage or encumber, abandon, permit to lapse, or otherwise dispose of any material intellectual property, except for non-exclusive licenses or non-exclusive sublicenses of owned intellectual property in the ordinary course of business, or (ii) fail to pay any fee, take any action or make any filing reasonably necessary to maintain the material intellectual property listed on a disclosure schedule to the merger agreement;
•: (i) take any action that would reasonably be likely to prevent or materially delay satisfaction of the mutual closing conditions and the closing conditions to the obligations of Parent and Merger Co or the consummation of the merger, or (ii) take any action that would have or would reasonably be expected to have a material adverse effect; or
•: announce an intention, agree or commit to do any of the foregoing.

Efforts to Complete the Merger

Subject to the terms and conditions set forth in the merger agreement, each of the parties to the merger agreement has agreed to use its reasonable best efforts to take, or cause to be taken, all actions, to file, or cause to be filed, all documents, and to do or cause to be done all things necessary, proper or advisable to consummate the transactions contemplated by the merger agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, consents, waivers, approvals, authorizations, permits or orders from all governmental authorities or other persons.

If any objections are asserted with respect to the transactions contemplated by the merger agreement under any law or if any suit is instituted (or threatened to be instituted) by any governmental authority or private party challenging any of the transactions or which would otherwise prevent, materially impede or materially delay the consummation of the transactions, each of Parent, Merger Co and the Company is required to use its reasonable best efforts to resolve any such objections or suits so as to permit consummation of the transactions, including in order to resolve such objections or suits which, in any case if not resolved, would reasonably be expected to prevent, materially impede or materially delay the consummation of the merger or the transactions contemplated by the merger agreement. In no event, however, will any party to the merger agreement be required to, and the Company may not without the prior written consent of Parent, take any actions

to resolve any objections or suits of governmental authorities which actions would reasonably be expected, individually or in the aggregate, to have a material adverse effect on the Company.

Parent has agreed to use its reasonable best efforts to arrange the debt financing to fund the proposed merger and related transactions contemplated by the debt financing commitments executed in connection with the merger agreement and to cause its financing sources to fund the financing required to consummate the proposed merger. The Company has agreed to cooperate in connection with the financing. See "The Transaction—Financing of the Merger" for a description of the financing arranged by Parent to fund the proposed merger and related transactions.

As promptly as reasonably practicable after the request of Parent, if any, the Company will commence a consent solicitation and/or debt tender offer for its outstanding Senior Subordinated Convertible Notes due 2035, or will cooperate with Parent in connection with any consent solicitation and/or debt tender offer by Parent or Merger Co, in each case, on such reasonable terms and conditions as proposed by Parent. However, any consent solicitation and/or debt tender offer shall not require payment for the notes and/or the consents to be made prior the effective time of the merger. The closing of any debt tender offer will be contingent upon the simultaneous completion of the proposed merger. Simultaneously with the completion of the proposed merger, Parent or Merger Co will provide to the Company the funds necessary to consummate any debt tender offer and/or consent solicitation (including the payment of all applicable premiums, consent fees and all related fees and expenses).

Marketing Period

Unless otherwise agreed by the parties to the merger agreement, the parties are required to close the merger on the third business day after the satisfaction or waiver of the conditions described under "—Conditions to the Merger" below, provided that if the marketing period has not ended at such time, the parties are obligated to close the merger on the date following the satisfaction or waiver of such conditions that is specified by Parent on no less than three business days' notice to the Company, such date to occur no later than five calendar days after the final day of the marketing period.

For purposes of the merger agreement, "marketing period" means the first period of twenty (20) consecutive business days after the execution of the Merger Agreement throughout which:

•: Parent has financial information of the type that is required or customarily would be included in connection with Parent's debt financing of the merger;
•: the Company has filed reports under the securities laws as may be customary in connection with Parent's debt financing of the merger; and
•: both the mutual closing conditions and the conditions to the obligations of Parent and Merger Co (other than delivery of an officer's certificate by the Company) to complete the merger are satisfied and nothing has occurred and no condition exists that would cause any of such conditions to fail to be satisfied assuming the closing were to be scheduled for any time during such twenty consecutive business day period.

If the marketing period would not end on or prior to December 15, 2006, the marketing period will be deemed to commence no earlier than January 2, 2007. In addition, the marketing period will not be deemed to have commenced if, prior to the completion of the marketing period, PricewaterhouseCoopers LLP shall have withdrawn its audit opinion with respect to any financial statements contained in our reports filed with the SEC since August 31, 2003.

The purpose of the marketing period is to provide the Sponsors a reasonable and appropriate period of time during which they can market and place the permanent debt financing contemplated by the debt financing commitments for the purposes of financing the merger. Parent has agreed:

•: to use reasonable best efforts to arrange the debt financing as promptly as practicable taking into account the expected timing of the marketing period and the termination date and to satisfy on a timely basis all conditions applicable to Parent in the debt financing commitments; and
•: in the event that any portion of the debt financing becomes unavailable on the terms and conditions contemplated in the debt financing commitments, to use its reasonable best efforts to arrange alternative financing on terms no less favorable to Parent with respect to conditions precedent to the debt financing (as determined in its reasonable judgment) as promptly as practicable but no later than five calendar days after the last day of the marketing period.

Employee Benefits

For one year after the effective time of the merger, the surviving corporation will provide each employee of the Company and its subsidiaries with base salary and incentive compensation opportunities (other than equity-based compensation) that are substantially comparable in the aggregate to those provided to such employees immediately prior to the effective time of the merger, and with employee benefits (other than equity-based compensation) that are substantially comparable in the aggregate to those provided to such employees immediately prior to the effective time of the merger.

Employees of the Company and its subsidiaries will receive credit for their services with the Company and any of its subsidiaries (including for purposes of eligibility to participate, vesting, benefit accrual and eligibility to receive benefits, but excluding benefit accruals under any defined benefit pension plan) under any employee benefit plan, program or arrangement established or maintained by Parent, the surviving corporation or any of their subsidiaries after the effective time of the merger to the same extent recognized by the Company or its subsidiaries under comparable plans prior to the effective time of the merger.

From and after the effective time of the merger, Parent will cause the surviving corporation and its subsidiaries to honor and perform our change in control protection plan for non-employee directors, executive officers and certain other employees.

No new offering periods under the Company's Employee Stock Purchase Plan, or ESPP, will be commenced following the execution date of the merger agreement. The final exercise under the ESPP will have occurred at the conclusion of the offering period in effect at the time of the execution of the merger agreement. Immediately prior to the effective time of the merger, the ESPP will be terminated.

Indemnification and Insurance

For a period of six years after the effective time of the merger, unless otherwise required by applicable law, the certificate of incorporation and bylaws (or equivalent organizational documents) of the surviving corporation and its subsidiaries shall contain provisions no less favorable with respect to the indemnification of and advancement of expenses to directors and officers than are set forth in the certificate of incorporation or bylaws (or equivalent organizational documents) of the Company (or the relevant subsidiary) as in effect on the date of the merger agreement. Parent will and will cause the surviving corporation to indemnify, and advance expenses (including, but not limited to, legal expenses and the cost of any investigation) to, each present and former director or officer of the Company and each subsidiary (which we refer to as an indemnified party), in and to the extent of their capacities as such and not as stockholders of the Company or any subsidiary, in respect of actions, omissions or events through the effective time of the merger to the fullest extent permitted by law. Parent will, and will cause the surviving corporation to, honor and perform under all indemnification agreements entered into by the Company or any of its subsidiaries prior to the date of the merger agreement.

The surviving corporation shall either:

•: cause to be obtained and shall maintain a "tail" insurance policy with a claims period of at least six years from the effective time of the merger with respect to directors' and officers' liability insurance in amount and scope, and with other material terms and conditions, at least as favorable as the Company's existing policies for claims arising from facts or events that occurred prior to the effective time of the merger; or
•: maintain the existing officers' and directors' liability insurance policies maintained by the Company (provided that the surviving corporation may substitute therefor policies of at least the same coverage containing terms and conditions that are not less favorable to the indemnified parties) for a period of six years after the effective time of the merger

so long as, in either case, the annual premium therefor is not in excess of 300% of the last annual premium paid prior to the date of the merger agreement; provided, however, that if the existing officers' and directors' liability insurance policies expire, are terminated or cancelled during such six-year period or require an annual premium in excess of 300% of the current premium paid by the Company for such insurance, the Company will obtain as much coverage as can be obtained for the remainder of such period for a premium not in excess of 300% (on an annualized basis) of such current premium.

Restrictions on Solicitations of Other Offers

Pursuant to the merger agreement, prior to 11:59 p.m. (EST), on November 8, 2006, we (acting under the direction of the Special Committee) were permitted to:

•: initiate, solicit and encourage acquisition proposals (including by way of providing non-public information); provided that we promptly provide to Parent any material non-public information concerning us or our subsidiaries that is provided to any person given such access which has not been provided to Parent; and
•: enter into and maintain discussions or negotiations with respect to acquisition proposals or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations.

Subject to the immediately preceding paragraph, we have agreed not to:

•: initiate, solicit or knowingly encourage (including by way of providing information or providing access to its properties, books, records or personnel) the submission of any inquiries, proposals or offers or any other efforts or attempts that constitute or may reasonably be expected to lead to, any acquisition proposal for us or engage in any discussions or negotiations with respect thereto or otherwise knowingly cooperate with or knowingly assist or participate in, or knowingly facilitate any such inquiries, proposals, discussions or negotiations; or
•: subject to limited exceptions, modify, waive, amend or release any standstill, confidentiality or similar agreements entered into by the Company or any of its subsidiaries prior to the date of the merger agreement or any confidentiality agreement entered into by the Company or any of its subsidiaries between the date of the merger agreement and the effective time of the merger;
•: neglect to enforce the provisions of any such standstill, confidentiality or similar agreements; or
•: approve or recommend, or publicly propose to approve or recommend, any acquisition proposal or enter into any merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement or share exchange agreement, option

agreement or other similar agreement providing for or relating to any acquisition proposal or enter into any agreement or agreement in principle requiring us to abandon, terminate or fail to consummate the transactions contemplated by the merger agreement or breach our obligations under the merger agreement or resolve or authorize or propose or agree to do any of the foregoing.

In addition, as of 11:59 p.m. (EST), on November 8, 2006, we agreed to cease and terminate with all persons any solicitations, encouragements, discussions or negotiations existing at such time, unless the acquisition proposal offered by such person met the requirements in the following paragraph (and only for so long as such proposal continues to meet those requirements). However, as of the end of the solicitation period on November 8, 2006, no party had submitted an acquisition proposal.

Notwithstanding the aforementioned restrictions, at any time prior to the approval of the merger agreement by our stockholders, we are permitted to engage in discussions or negotiations with, or provide any non-public information to any party to the extent that:

•: we receive from such party an acquisition proposal not solicited in violation of the prohibitions described above and which the board of directors (acting through the special committee if such committee still exists) believes in good faith to be bona fide;
•: our board of directors (acting through the special committee if such committee still exists) determines in good faith, after consultation with its independent financial advisors and outside legal counsel, that the acquisition proposal constitutes or could reasonably be expected to result in a superior proposal; and
•: after consultation with its outside counsel, our board of directors (acting through the special committee if such committee still exists) determines in good faith that the failure to take such action would be inconsistent with its fiduciary duties under applicable law.

In such cases, we (i) will not, and will not allow our representatives to, disclose any non-public information to such person without entering into a confidentiality agreement on terms no more favorable to such person than those contained in the confidentiality agreements entered into with the Sponsors (provided that such confidentiality agreements may permit such person to disclose information concerning the Company to such person's potential debt financing sources (and to the extent permitted by the special committee in accordance with the merger agreement, potential equity financing sources as well)) and (ii) will promptly provide to Parent any non-public information concerning us or our subsidiaries provided to such other person which has not been provided to Parent.

From and after 11:59 p.m. (EST), on November 8, 2006, we will within 24 hours notify Parent in the event we receive an acquisition proposal from a person or group of related persons, including the material terms and conditions thereof, and will keep Parent apprised as to the status and any material developments, discussions and negotiations concerning the same on a current basis (and in any event no later than 24 hours after the occurrence of such developments, discussions or negotiations). Without limiting the foregoing, we will within 24 hours notify Parent orally and in writing if we determine to begin providing information or to engage in negotiations concerning an acquisition proposal from a person or group of related persons. Within 24 hours of 11:59 p.m. (EST), on November 8, 2006, we will notify Parent of the number of parties who have submitted an acquisition proposal as of such date that meets the requirements for permitted discussions and negotiations as set forth in the preceding paragraph and provide Parent a written summary of the material terms and conditions of each such acquisition proposal received from such parties and, thereafter, keep Parent apprised as to the status and material developments, discussions and negotiations concerning the same on a current basis (and in any event no later than 24 hours after the occurrence of such developments, discussions or negotiations).

An "acquisition proposal" means any inquiry, proposal or offer from any person or group of persons (other than Parent, Merger Co or their respective affiliates) relating to any direct or indirect

acquisition or purchase of 15% or more of the assets, net revenues or net income of us and our subsidiaries, taken as a whole, or 15% or more of any class of our equity securities then outstanding, any tender offer or exchange offer that if consummated would result in any person beneficially owning 15% or more of any class of our equity securities then outstanding, or any merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving us (or any of our subsidiaries whose business constitutes 15% or more of the assets, net revenues or net income of our and our Subsidiaries, taken as a whole), other than as contemplated by the merger agreement.

A "superior proposal" means an acquisition proposal for us not solicited in violation of the merger agreement that relates to an acquisition of more than 50% of the outstanding common stock of the Company or more than 50% of the assets, net revenues or income of the Company and its subsidiaries, taken as a whole, that our board of directors (acting through, or based upon the advice of, the special committee, if such committee still exists) in good faith determines, would, if consummated, result in a transaction that is more favorable from a financial point of view to the stockholders than the transactions contemplated in the merger agreement (x) after receiving the advice of SunTrust Robinson Humphrey, or another nationally recognized financial advisor, (y) after taking into account the likelihood of consummation of such transaction on the terms set forth therein (as compared to the terms in the merger agreement, as such terms may be adjusted as provided in the merger agreement) and (z) after taking into account all appropriate legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory or other aspects of such proposal.

Recommendation Withdrawal/Termination in Connection with a Superior Proposal

Our board of directors (acting through, or based upon the advice of, the special committee if such committee still exists) may also, at any time prior to the approval of the merger agreement by our stockholders:

•: (i) withdraw (or modify or qualify in a manner adverse to Parent or Merger Co), or publicly propose to withdraw (or modify or qualify in a manner adverse to Parent or Merger Co), its recommendation that the stockholders of the Company adopt the merger agreement, (ii) take any other action or make any other public statement in connection with the special meeting inconsistent with such recommendation or (iii) approve or recommend, or propose publicly to approve or recommend, any acquisition proposal (the foregoing actions are referred to as a "recommendation withdrawal"); or
•: terminate the merger agreement and enter into a definitive agreement,

in each case, with respect to a superior proposal if it determines in good faith (after consultation with its legal advisors) that failure to do so would be inconsistent with its fiduciary duties under applicable law; but only after (i) we give written notice to Parent and Merger Co at least 72 hours in advance of our intention to do so and (ii) prior to effecting such action, during such 72 hour period, we negotiate with (and cause our financial and legal advisors to negotiate with) Parent and Merger Co in good faith (to the extent Parent and Merger Co desire to negotiate) to make such adjustments in the terms and conditions of the merger agreement so that such acquisition proposal ceases to constitute a superior proposal. In addition, in the event we terminate the merger agreement and enter into a definitive agreement with respect to a superior proposal, we must concurrently with such termination pay to Parent the termination fee as described in further detail below in "—Termination Fees; Expense Reimbursement."

Conditions to the Merger

•: the merger agreement must have been adopted by a majority of the outstanding shares of Open Solutions' common stock entitled to vote thereon;

•: the Company's representations and warranties with respect to certain matters relating to the Company's capitalization and authority must be true in all material respects as of the effective time of the merger as if made at and as of the effective time (except to the extent that any representations expressly speaks as of an earlier date, in which case, such representation shall be true and correct as of such earlier date);
•: all other representations and warranties made by the Company in the merger agreement, with the exception of those listed above, must be true and correct as of the effective time of the merger as if made at and as of such time (without giving effect to any qualification as to material adverse effect, materiality or similar qualifiers set forth in such representations and warranties), except where the failure to be so true and correct, individually or in the aggregate, has not had, and would not reasonably be expected to have, a material adverse effect on the Company; provided that any representations made by the Company as of a specific date need only be so true and correct (disregarding any material adverse effect, materiality or similar qualifiers) as of the date made;
•: the Company must have performed or complied in all material respects with all agreements and covenants that the Company is required to perform under the merger agreement at or prior to the effective time of the merger;

•: Merger Co must have performed or complied in all material respects with all agreements and covenants that it is required to perform under the merger agreement at or prior to the effective time of the merger; and
•: Merger Co must have delivered to the Company at closing a certificate with respect to the satisfaction of the foregoing conditions relating to representations, warranties, agreements and covenants.

Termination of the Merger Agreement

The merger agreement may be terminated at any time prior to the consummation of the merger, whether before or after stockholder approval has been obtained:

•

by mutual written consent of the Company and Parent;

•

by either the Company or Parent, if:

•: the merger is not consummated on or before March 31, 2007, unless such failure is the result of, or caused by, the terminating party's failure to observe any obligation under the merger agreement;
•: there is any final and nonappealable injunction, order, decree or ruling that makes consummation of the merger illegal or otherwise prevents or prohibits the consummation of the merger; or
•: our stockholder, at the special meeting or at any adjournment thereof, fail to adopt the merger agreement;

•

by Parent if:

•: we have breached any of our representations, warranties, covenants or agreements under the merger agreement which would give rise to the failure of certain conditions to closing and where that breach has not been, or cannot be, cured on or before March 31, 2007; provided that neither Parent nor Merger Co is then in material breach of the merger agreement so as to cause certain conditions to closing to not be satisfied; or
•: our board of directors or the special committee (i) effects a recommendation withdrawal or publicly proposes a recommendation withdrawal; (ii) approves or recommends to the stockholders of the Company an acquisition proposal for us other than the merger contemplated by the merger agreement, or shall have resolved to effect the foregoing; or (iii) fails to include the recommendation in our proxy statement in connection with the merger;

•

by the Company if:

•: Parent or Merger Co has breached any of its representations, warranties, covenants or agreements under the merger agreement which would give rise to the failure of certain conditions to closing and where that breach has not been, or cannot be, cured on or before March 31, 2007, provided that the Company is not in material breach of the merger agreement so as to cause the closing conditions relating to Parent and Merger Co's obligations to consummate the merger not to be satisfied;
•: prior to obtaining stockholder approval, we terminate the merger agreement in order to enter into an agreement with respect to a superior proposal, provided that the Company complies with the terms described above in "—Recommendation Withdrawal/Termination in Connection with a Superior Proposal," including that the Company pays to Parent concurrently with termination the termination fee described below; or

•: if all conditions to the obligations of Parent and Merger Co (other than delivery of an officer's certificate) have been satisfied and Parent fails to consummate the merger no later than five calendar days after the final day of the marketing period.

Termination Fees; Expense Reimbursement

Payable by the Company

We have agreed to reimburse Parent's actual and reasonably documented out-of-pocket fees and expenses incurred on or prior to the termination the merger agreement in connection with the transactions contemplated by the merger agreement, up to a maximum of $5 million, if no termination fee is otherwise payable and the merger agreement is terminable or was terminable:

•: by either the Company or Parent because of the failure to receive Company stockholder approval at the special meeting or any adjournment thereof; or
•: by Parent because of a material breach of our representations, warranties, covenants or agreements such that the closing conditions would not be satisfied and such breach has not been or cannot be cured on or before March 31, 2007,

or, in either case, we terminate the merger agreement in accordance with its terms at a time when the merger agreement was terminable for either of the foregoing reasons.

If we terminate the merger agreement (other than by mutual agreement of the parties), or the merger agreement is terminated by Parent under the conditions described in further detail below, we must pay a termination fee at the direction of Parent. The termination fee is $30 million. If we terminated the merger agreement in accordance with its terms in order to enter into a definitive agreement with respect to an acquisition proposal on or prior to 11:59 p.m., New York time, on November 8, 2006, such termination fee would have been $12 million.

We must pay a termination fee at the direction of Parent if:

•

we terminate the merger agreement, prior to the stockholders meeting, because we receive an acquisition proposal which we determine to be a superior proposal, but only after we have provided notice to Parent regarding the superior proposal and provided Parent with at least a 72 hour period, during which time we must negotiate in good faith with Parent, to enable Parent to make an offer that results in the other acquisition proposal no longer being a superior proposal;

•

Parent terminates the merger agreement because

•: our board of directors or the special committee withdraws (or modifies or qualifies in a manner adverse to Parent or Merger Co), or publicly proposes to withdraw (or modify or qualify in a manner adverse to Parent or Merger Co), its recommendation that our stockholders adopt the merger agreement or takes any other action or makes any other public statement inconsistent with such recommendation or approves or recommends, or proposes to publicly approve or recommend any acquisition proposal for us;
•: our board of directors or the special committee approves or recommends to our stockholders an acquisition proposal for us other than the merger contemplated by the merger agreement, or shall have resolved to effect the foregoing; or
•: we fail to include in our proxy statement the recommendation of our board of directors that our stockholders adopt the merger agreement; or

•

the merger agreement is terminated (i) by us or Parent because the Company's stockholders fail to approve the merger agreement, (ii) by Parent because we have breached any of our representations, warranties, covenants or agreements under the merger agreement which would give rise to the failure of certain conditions to closing and where that breach has not been, or cannot be, cured on or before March 31, 2007 (provided that neither Parent nor Merger Co is then in material breach of the merger agreement so as to cause certain

conditions to closing to not be satisfied) or (iii) by us or Parent because the transactions have not been consummated by March 31, 2007; and

•: prior to the event giving rise to the termination, a bona fide acquisition proposal involving the purchase of more than 50% of the outstanding common stock or more than 50% of the assets, net revenues or income of the Company and its subsidiaries, taken as a whole, is publicly announced or publicly made known (and in the case of a termination pursuant to clause (i) above not both publicly withdrawn and publicly rejected by the board, in each case, at least twenty business days prior to the special meeting); and within 12 months after the termination, the Company enters into a definitive agreement with respect to, or consummates, any acquisition proposal involving the purchase of more than 50% of the outstanding common stock or more than 50% of the assets, net revenues or income of the Company and its subsidiaries, taken as a whole (whether or not the same as that originally publicly announced or publicly made known); or
•: within 12 months after the termination, the Company enters into a definitive agreement with respect to, or consummates, any acquisition proposal involving the purchase of more than 50% of the outstanding common stock or more than 50% of the assets, net revenues or income of the Company and its subsidiaries, taken as a whole, involving a person or any of its affiliates that entered into a confidentiality agreement with respect to the Company or any of its subsidiaries prior to such termination.

If we are obligated to pay a termination fee under this scenario, any amounts previously paid to Parent as expense reimbursement will be credited toward the termination fee amount payable by us.

Payable by Parent

Parent has agreed to pay us a termination fee of $30 million if:

•: we terminate the merger agreement because Parent or Merger Co has breached any of its representations, warranties, covenants or agreements under the merger agreement which would give rise to the failure of certain of the Company's conditions to closing to be satisfied and where that breach has not been, or cannot be, cured by March 31, 2007 (provided that we are not then in material breach of the merger agreement so as to cause certain conditions to closing to not be satisfied) and no facts or circumstances exist that would reasonably be expected to cause Parent and Merger Co's conditions to closing not to be satisfied; or
•: we terminate the merger agreement because certain conditions to the obligations of Parent and Merger Co have been satisfied and Parent fails to consummate the merger no later than five calendar days after the final day of the marketing period.

Amendment, Extension and Waiver

The parties may amend the merger agreement at any time; provided, however, that after we have obtained our stockholders' approval of the merger, there shall be no amendment that by law requires further approval by our stockholders without such approval having been obtained. All amendments to the merger agreement must be in writing signed by the Company, Parent and Merger Co.

At any time before the consummation of the merger, each of the parties to the merger agreement may, by written instrument:

•: extend the time for the performance of any obligation or other act of any other party;
•: waive any inaccuracy in the representations and warranties of any other party contained in the merger agreement or in any document delivered pursuant to the merger agreement; or
•: subject to the requirements of applicable law, waive compliance with any agreement of any other party or any condition to its own obligations contained in the merger agreement.

RIGHTS OF APPRAISAL

Under the DGCL, you have the right to demand appraisal of your shares and to receive, in lieu of the merger consideration, payment in cash for the fair value of your common stock of the Company as determined by the Delaware Court of Chancery, exclusive of any element of value arising from the accomplishment of the merger, together with a fair rate of interest. The Company's stockholders electing to exercise appraisal rights must strictly comply with the provisions of Section 262 of the DGCL in order to perfect their rights.

The following is intended as a brief summary of the material provisions of the Delaware statutory procedures required to be followed by a stockholder in order to demand and perfect appraisal rights and is qualified in its entirety by reference to Section 262 of the DGCL, the full text of which appears in Annex C to this proxy statement.

Section 262 requires that stockholders be notified that appraisal rights will be available not less than 20 days before the special meeting to vote on the adoption of the merger agreement. A copy of Section 262 must be included with such notice. This proxy statement constitutes the Company's notice to its stockholders of the availability of appraisal rights in connection with the merger in compliance with the requirements of Section 262. If you wish to consider exercising your appraisal rights, you should carefully review the text of Section 262 contained in Annex C since failure to timely and properly comply with the requirements of Section 262 will result in the loss of your appraisal rights under Delaware law.

If you elect to demand appraisal of your shares, you must satisfy each of the following conditions:

•: You must be a holder of record of shares of our common stock on the date that the written demand for appraisal is made, and you must continue to hold the shares of record through the effective date of the merger.
•: You must deliver to the Company a written demand for appraisal of your shares before the vote with respect to the merger agreement is taken at the special meeting. This written demand for appraisal must be in addition to and separate from any proxy or vote abstaining from or voting against the adoption of the merger agreement. Voting against or failing to vote for the adoption of the merger agreement by itself does not constitute a demand for appraisal within the meaning of Section 262.
•: You must not vote in favor of the adoption of the merger agreement. A vote in favor of the adoption of the merger agreement, by proxy or in person, will constitute a waiver of your appraisal rights in respect of the shares so voted and will nullify any previously filed written demands for appraisal.

If you fail to comply with any of these conditions and the merger is completed, you will be entitled to receive the cash payment for your shares of the Company's common stock as provided for in the merger agreement, but you will have no appraisal rights with respect to your shares of the Company's common stock. A proxy card which is signed and does not contain voting instructions will, unless revoked, be voted "FOR" the adoption of the merger agreement and will constitute a waiver of your right of appraisal and will nullify any previous written demand for appraisal. If the written demand for appraisal is made in accordance with the requirements of Delaware law, failure to vote against the proposal to adopt the merger agreement (i.e., abstaining) will not operate as a waiver of your appraisal rights.

All demands for appraisal should be in writing and addressed to Open Solutions Inc., 455 Winding Brook Drive, Glastonbury, CT 06033, Attention: General Counsel, before the vote on the merger agreement is taken at the special meeting, and should be executed by, or on behalf of, the record holder of the shares in respect of which appraisal is being demanded. The demand must reasonably inform the Company of the identity of the stockholder and the intention of the stockholder to demand appraisal of his, her or its shares.

To be effective, a demand for appraisal by a holder of the Company's common stock must be made by, or in the name of, such registered stockholder, fully and correctly, as the stockholder's name appears on his or her stock certificate(s). The demand should specify the holder's name and mailing address and the number of shares registered in the holder's name and must state that the person intends thereby to demand appraisal of the holder's shares in connection with the merger. Beneficial owners who do not also hold the shares of record may not directly make appraisal demands to the Company. The beneficial holder must, in such cases, have the registered owner submit the required demand in respect of those shares. If shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of a demand for appraisal should be made in that capacity; and if the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or for all joint owners. An authorized agent, including an authorized agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, he or she is acting as agent for the record owner. A record owner, such as a broker, who holds shares as a nominee for others, may exercise his or her right of appraisal with respect to the shares held for one or more beneficial owners, while not exercising this right for other beneficial owners. In that case, the written demand should state the number of shares as to which appraisal is sought. Where no number of shares is expressly mentioned, the demand will be presumed to cover all shares held in the name of the record owner.

If you hold your shares of the Company's common stock in a brokerage account or in other nominee form and you wish to exercise appraisal rights, you should consult with your broker or the other nominee to determine the appropriate procedures for the making of a demand for appraisal by the nominee.

Within ten days after the effective time of the merger, the surviving corporation must give written notice that the merger has become effective to each Company stockholder who has properly filed a written demand for appraisal and who did not vote in favor of the merger agreement. At any time within 60 days after the effective time, any stockholder who has demanded an appraisal has the right to withdraw the demand and to accept the cash payment specified by the merger agreement for such stockholder's shares of the Company's common stock. Within 120 days after the effective time, either the surviving corporation or any stockholder who has complied with the requirements of Section 262 may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares held by all stockholders entitled to appraisal. The surviving corporation has no obligation and has no present intention to file such a petition in the event there are dissenting stockholders. Accordingly, the failure of a stockholder to file such a petition within the period specified could nullify the stockholder's previously written demand for appraisal. Within 120 days after the effective date of the merger, any holder of our common stock who has complied with the requirements for exercise of appraisal rights under Section 262 will be entitled, upon written request, to receive from the surviving corporation a statement setting forth the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. The statement must be mailed to such holder within ten days after a written request for the statement has been received by the surviving corporation.

If a petition for appraisal is duly filed by a stockholder and a copy of the petition is delivered to the surviving corporation, the surviving corporation will then be obligated, within 20 days after receiving service of a copy of the petition, to provide the Chancery Court with a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached. After notice to dissenting stockholders, the Chancery Court is empowered to conduct a hearing upon the petition, and to determine those stockholders who have complied with Section 262 and who have become entitled to the appraisal rights provided thereby. The Chancery Court may require the stockholders who have demanded payment for their shares to submit their stock certificates to the Register in Chancery for

notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with that direction, the Chancery Court may dismiss the proceedings as to that stockholder.

After determination of the stockholders entitled to appraisal of their shares of the Company's common stock, the Chancery Court will appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. When the value is determined, the Chancery Court will direct the payment of such value, with interest thereon accrued during the pendency of the proceeding, if the Chancery Court so determines, to the stockholders entitled to receive the same, upon surrender by such holders of the certificates representing those shares.

In determining fair value and, if applicable, a fair rate of interest, the Chancery Court is required to take into account all relevant factors. In Weinberger v. UOP, Inc., the Supreme Court of Delaware discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that "proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court" should be considered, and that "fair price obviously requires consideration of all relevant factors involving the value of a company." The Delaware Supreme Court stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts that could be ascertained as of the date of the merger that throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be "exclusive of any element of value arising from the accomplishment or expectation of the merger." In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a "narrow exclusion [that] does not encompass known elements of value," but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Supreme Court of Delaware also stated that "elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered." You should be aware that the fair value of your shares as determined under Section 262 could be more, the same, or less than the value that you are entitled to receive under the terms of the merger agreement.

Costs of the appraisal proceeding may be imposed upon the surviving corporation and the stockholders participating in the appraisal proceeding by the Chancery Court as the Chancery Court deems equitable in the circumstances. Upon the application of a stockholder, the Chancery Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys' fees and the fees and expenses of experts, to be charged pro rata against the value of all shares entitled to appraisal. Any stockholder who had demanded appraisal rights will not, after the effective time, be entitled to vote shares subject to that demand for any purpose or to receive payments of dividends or any other distribution with respect to those shares, other than with respect to payment as of a record date prior to the effective time; however, if no petition for appraisal is filed within 120 days after the effective time of the merger, or if the stockholder delivers a written withdrawal of such stockholder's demand for appraisal and an acceptance of the terms of the merger within 60 days after the effective time of the merger, then the right of that stockholder to appraisal will cease and that stockholder will be entitled to receive the cash payment for shares of his, her or its Company common stock pursuant to the merger agreement. Any withdrawal of a demand for appraisal made more than 60 days after the effective time of the merger may only be made with the written approval of the surviving corporation. Once a petition for appraisal has been filed, the appraisal proceeding may not be dismissed as to any stockholder without the approval of the Chancery Court.

Failure to comply with all of the procedures set forth in Section 262 will result in the loss of a stockholder's statutory appraisal rights. In view of the complexity of Section 262, the Company's stockholders who may wish to dissent from the merger and pursue appraisal rights should consult their legal advisors.

MULTIPLE STOCKHOLDERS SHARING ONE ADDRESS

In accordance with Rule 14a-3(e)(1) under the Exchange Act, one proxy statement will be delivered to two or more stockholders who share an address, unless the Company has received contrary instructions from one or more of the stockholders. The Company will deliver promptly upon written or oral request a separate copy of the proxy statement to a stockholder at a shared address to which a single copy of the proxy statement was delivered. Requests for additional copies of the proxy statement, and requests that in the future separate proxy statements be sent to stockholders who share an address, should be directed to our Investor Relations Department, at Open Solutions Inc., 455 Winding Brook Drive, Glastonbury, Connecticut 06033, or by calling our Investor Relations Department at (860) 652-3155. In addition, stockholders who share a single address but receive multiple copies of the proxy statement may request that in the future they receive a single copy by contacting our Investor Relations Department at the address and phone number set forth in the prior sentence.

SUBMISSION OF STOCKHOLDER PROPOSALS

If the merger is completed, we do not expect to hold an annual meeting in 2007. If the merger is not completed, you will continue to be entitled to attend and participate in our stockholder meetings and we will hold a 2007 annual meeting of stockholders, in which case stockholder proposals will be eligible for consideration for inclusion in the proxy statement and form of proxy for our 2007 annual meeting of stockholders in accordance with Rule 14a-8 under the Exchange Act. To be eligible for inclusion in the proxy statement and form of proxy for the 2007 annual meeting pursuant to Rule 14a-8, proposals of stockholders must have been received by us no later than December 21, 2006 and must comply with Rule 14a-8. If the date of the 2007 annual meeting, if any, is changed by more than 30 days from May 16, 2007, then in order to be considered for inclusion in the Company's proxy materials, proposals of stockholders intended to be presented at the 2007 annual meeting must be received by us a reasonable time before we begin to print and mail our proxy materials for the 2007 annual meeting. In order to curtail controversy as to the date on which a proposal was received by us, we suggest that proponents submit their proposals by certified mail, return receipt requested, to Open Solutions Inc., 455 Winding Brook Drive, Glastonbury, CT 06033, Attention: Corporate Secretary.

In addition, our bylaws provide that stockholders seeking to nominate candidates for election as directors at an annual meeting of stockholders, must provide timely notice thereof in writing. To be timely, a stockholder's notice must be received by the Corporate Secretary at the address set forth above not less than 60 nor more than 90 days in advance of the first anniversary of the preceding year's annual meeting of stockholders (which was May 16, 2006). If the date of the annual meeting is advanced more than 20 days prior to or delayed by more than 60 days after the anniversary of the preceding year's annual meeting, notice by the stockholder to be timely must be so delivered not later than the close of business on the later of (i) the 60th day prior to the annual meeting and (ii) the 10th day following the day on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever first occurs.

AGREEMENT AND PLAN OF MERGER, dated as of October 14, 2006 (this "Agreement"), among HARPOON ACQUISITION CORPORATION, a Delaware corporation ("Parent"), HARPOON MERGER CORPORATION, a Delaware corporation and a wholly-owned subsidiary of Parent ("Merger Co"), and OPEN SOLUTIONS INC, a Delaware corporation (the "Company").

WHEREAS, the respective Boards of Directors of each of the Company, Parent and Merger Co (and with respect to the Company, based on the unanimous recommendation of the Special Committee of the Board of Directors of the Company (the "Special Committee")) deem it in the best interests of their respective stockholders to consummate the merger (the "Merger"), on the terms and subject to the conditions set forth in this Agreement, of Merger Co with and into the Company, and such Boards of Directors have approved this Agreement and declared its advisability (and, in the case of the Board of Directors of the Company (the "Company Board"), recommended that this Agreement be adopted by the Company's stockholders).

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements herein contained, and intending to be legally bound hereby, Parent, Merger Co and the Company hereby agree as follows:

ARTICLE I.
THE MERGER

SECTION 1.01 The Merger. Upon the terms and subject to the conditions set forth in Article VII, and in accordance with the General Corporation Law of the State of Delaware (the "DGCL"), at the Effective Time, Merger Co shall be merged with and into the Company. At the Effective Time, the separate corporate existence of Merger Co shall cease and the Company shall continue as the surviving corporation of the Merger (the "Surviving Corporation").

SECTION 1.02 Closing. Unless this Agreement shall have been terminated in accordance with Section 8.01 or another time, date and/or place is agreed to in writing by Parent and the Company, the closing of the Merger (the "Closing") will take place at 11:00 a.m., New York time, at the offices of Latham & Watkins LLP, 885 Third Avenue, Suite 1000, New York, NY, 10022-4834, on the third business day after the satisfaction or waiver of the conditions set forth in Article VII (excluding conditions that, by their terms, cannot be satisfied until the Closing but subject to the satisfaction or waiver of such conditions at the Closing); provided, however, that if the fifth calendar day after the final day of the Marketing Period (as herein defined) has not occurred at the time of the satisfaction or waiver of the conditions set forth in Article VII (excluding conditions that, by their terms, cannot be satisfied until the Closing but subject to the satisfaction or waiver of such conditions at the Closing), the Closing shall occur on the date following the satisfaction or waiver of such conditions that is specified by Parent on no less than three business days' notice to the Company, such date to occur no later than five calendar days after the final day of the Marketing Period. The date on which the Closing actually occurs is hereinafter referred to as the "Closing Date".

SECTION 1.03 Effective Time. Upon the terms and subject to the conditions set forth in this Agreement, on the Closing Date, the parties hereto shall file, or cause to be filed, a certificate of merger (the "Certificate of Merger") in such form as is required by, and executed and acknowledged in accordance with, the relevant provisions of the DGCL. The Merger shall become effective at such date and time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware or at such subsequent date and time as Merger Co and the Company shall agree and specify in the Certificate of Merger. The date and time at which the Merger becomes effective is referred to in this Agreement as the "Effective Time".

SECTION 1.04 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in Section 259 of the DGCL.

SECTION 1.05 Certificate of Incorporation; Bylaws. (a) At the Effective Time, the Certificate of Incorporation of the Company as in effect immediately prior to the Effective Time shall be amended as of the Effective Time to read in its entirety as set forth in Exhibit B attached hereto and, as so

amended, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended (subject to the requirements of Section 6.05(a)) in accordance with the provisions thereof and as provided by Law.

(b) At the Effective Time, the Bylaws of Merger Co as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by Law, the Certificate of Incorporation of the Surviving Corporation and such Bylaws.

ARTICLE II.
CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

SECTION 2.01 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Co, the Company or the holders of any of the following securities:

(a) Conversion of Company Common Stock. Each share of common stock, par value $.01 per share, of the Company (the "Company Common Stock") issued and outstanding immediately prior to the Effective Time (such shares, including any shares issued upon conversion of the Convertible Notes, the "Shares") (other than any Shares to be cancelled pursuant to Section 2.01(b) and any Dissenting Shares) shall be canceled and shall be converted automatically into the right to receive $38.00 in cash, without interest (the "Merger Consideration"), payable upon surrender in the manner provided in Section 2.02 of the certificate that formerly evidenced such Share (a "Certificate").

(b) Cancellation of Treasury Stock and Parent and Merger Co-Owned Stock. Each share of Company Common Stock held in the treasury of the Company and each share of Company Common Stock owned by Parent, Merger Co or any direct or indirect wholly-owned subsidiary of Parent or Merger Co or any direct or indirect wholly-owned Subsidiary of the Company immediately prior to the Effective Time shall automatically be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto.

(c) Capital Stock of Merger Co. Each share of common stock, par value $.01 per share, of Merger Co issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation. Following the Effective Time, each certificate evidencing ownership of shares of Merger Co common stock shall evidence ownership of such shares of the Surviving Corporation.

(d) Adjustments. If, between the date of this Agreement and the Effective Time, there is a reclassification, recapitalization, stock split, stock dividend, subdivision, combination or exchange of shares with respect to, or rights issued in respect of, the Shares (other than the conversion of Convertible Notes into Shares or the issuance of Shares upon the exercise of Company Stock Options or the vesting of RSUs), the Merger Consideration shall be adjusted accordingly, without duplication, to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to such event.

SECTION 2.02 Exchange of Certificates. (a) Paying Agent. Prior to the Effective Time, the Company shall (i) appoint a bank or trust company reasonably acceptable to Parent (the "Paying Agent"), and (ii) enter into a paying agent agreement, in form and substance reasonably acceptable to Parent, with such Paying Agent, to serve as the Paying Agent for the payment of the Merger Consideration in accordance with this Article II and payments in respect of the Company Stock Options and RSUs unless another agent is designated as provided in Section 2.04(a) or Section 2.04(b). At the Effective Time, the Surviving Corporation shall deposit, or Parent shall cause the Surviving Corporation to deposit, with the Paying Agent for the benefit of the holders of Shares, Company Stock Options and RSUs, cash in an amount sufficient to pay the aggregate Merger Consideration required to be paid pursuant to Section 2.01(a) plus any cash payable to holders of Company Stock Options and RSUs pursuant to Section 2.04 (such cash being hereinafter referred to as the "Exchange Fund"). The Exchange Fund shall not be used for any other purpose. The Exchange Fund shall be invested by the Paying Agent as directed by the Surviving Corporation; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody's Investors Service, Inc. or Standard & Poor's Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker's acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank which are then publicly available). Any net profit resulting from, or interest or income produced by, such investments shall be payable to the Surviving Corporation.

(b) Exchange Procedures. As promptly as practicable after the Effective Time, but in any event within 4 business days after the Effective Time, the Company shall cause the Paying Agent to mail to each Person who was, immediately prior to the Effective Time, a holder of record of Shares entitled to receive the Merger Consideration pursuant to Section 2.01(a): (i) a letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates evidencing such Shares shall pass, only upon proper delivery of the Certificates to the Paying Agent) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender to the Paying Agent of a Certificate or Certificates for cancellation, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash that such holder has the right to receive in respect of the Shares formerly represented by such Certificate pursuant to Section 2.01(a), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a Person other than the Person in whose name the Certificate so surrendered is registered if the Certificate representing such Shares shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration to which the holder of such Certificate is entitled pursuant to this Article II. No interest shall be paid or will accrue on any cash payable to holders of Certificates pursuant to the provisions of this Article II.

(c) No Further Rights. From and after the Effective Time, holders of Certificates shall cease to have any rights as stockholders of the Company, except as otherwise provided herein or by Law.

(d) Exchange Fund for Dissenting Shares. Any portion of the Exchange Fund deposited with the Paying Agent pursuant to Section 2.02(a) to pay for Shares that become Dissenting Shares shall be

A-3

delivered to the Surviving Corporation upon demand following the filing of a petition for appraisal of the Shares with the Delaware Court of Chancery; provided, however, that Parent and the Surviving Corporation shall remain liable for payment of the Merger Consideration for such Shares held by any stockholder who shall have failed to perfect or who otherwise shall have withdrawn or lost such stockholder's rights to appraisal of such Shares under Section 262 of the DGCL ("Section 262").

(e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares for one year after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Shares who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for, and the Surviving Corporation shall remain liable for, payment of their claim for the Merger Consideration. Any portion of the Exchange Fund remaining unclaimed by holders of Shares as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation on such date, free and clear of any claims or interest of any Person previously entitled thereto.

(f) No Liability. None of the Paying Agent, Parent, Merger Co or the Surviving Corporation shall be liable to any holder of Shares for any such Shares (or dividends or distributions with respect thereto), or cash properly delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(g) Withholding Rights. Each of the Paying Agent, the Surviving Corporation and Merger Co shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as it is required to deduct and withhold with respect to such payment under all applicable Tax laws and pay such withholding amount over to the appropriate taxing authority. To the extent that amounts are so properly withheld by the Paying Agent, the Surviving Corporation or Merger Co, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by the Paying Agent, the Surviving Corporation or Merger Co, as the case may be.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation or the Paying Agent may direct, as indemnity against any claim that may be made against the Surviving Corporation with respect to such Certificate, the Paying Agent shall pay in respect of such lost, stolen or destroyed Certificate the Merger Consideration to which the holder thereof is entitled pursuant to Section 2.01(a).

SECTION 2.03 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Shares thereafter on the records of the Company other than to settle transfers of Shares that occurred prior the Effective Time. On or after the Effective Time, any Certificates presented to the Paying Agent or the Surviving Corporation for any reason shall be cancelled against delivery of the Merger Consideration to which the holders thereof are entitled pursuant to Section 2.01(a).

SECTION 2.04 Company Stock Options. (a) Except as provided for in Section 2.04(b), each option to purchase shares of Company Common Stock (the "Company Stock Options") granted under any plan arrangement or agreement, other than the ESPP (the "Company Stock Plans"), which is outstanding immediately prior to the Effective Time, whether or not then exercisable or vested, shall by virtue of the Merger and without any action on the part of the Parent, Merger Co, the Company or the holder thereof, be converted into and shall become a right to receive an amount in cash, without interest, with respect to each share that such Company Stock Option is then convertible into, equal to

A-4

the excess, if any, of the Merger Consideration over the per share exercise price of such Company Stock Option (such amount being hereinafter referred to as the "Option Merger Consideration") and each Company Stock Option shall be canceled at the Effective Time. The payment of Option Merger Consideration to the holder of a Company Stock Option shall be reduced by any income or employment tax withholding required under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of such Company Stock Option. The Company agrees to take any and all actions necessary to effectuate immediately prior to the Effective Time the cancellation of all Company Stock Options that are eligible for the Option Merger Consideration pursuant to this Section 2.04(a). All payments with respect to Company Stock Options shall be made by the Paying Agent (or such other agent reasonably acceptable to Parent as the Company shall designate prior to the Effective Time, which may be the Company's payroll agent) as promptly as reasonably practicable after the Effective Time from funds deposited by or at the direction of the Surviving Corporation to pay such amounts in accordance with Section 2.02(a).

(b) Notwithstanding the provisions of Section 2.04(a) that provide for the cancellation of the unexercised Company Stock Options, Parent, in its sole discretion, may permit the holders of certain Company Stock Options (the "Rollover Optionees") to exchange some or all of their outstanding Company Stock Options and receive substituted options to purchase common stock of Parent on such terms and conditions as are reasonably acceptable to Parent. Section 2.04(b) of the disclosure schedule delivered by the Company to Parent and Merger Co concurrently with the execution and delivery of this Agreement (the "Company Disclosure Schedule") sets forth the Rollover Optionees, which schedule may be amended and revised by Parent prior to the Closing Date. Parent intends that the exchange and substitution of the Company Stock Options for new options shall be effected in a manner, including but not limited to adjustments to the exercise price of the new options, that satisfies the requirements of Section 409A of the Code and the requirements of Treasury Regulation Section 1.424-1 to the extent that such requirements can be satisfied in light of the intended terms of the new options. Parent and the Company will cooperate to take such actions as they reasonably agree are necessary to effectuate the transactions contemplated by this Section 2.04(b).

SECTION 2.05 Restricted Shares; RSUs.

(a) As of the Effective Time, except as otherwise agreed by Parent and a holder of Restricted Shares with respect to such holder's Restricted Shares, each award of Restricted Shares which is outstanding immediately prior to the Effective Time shall vest in full and become free of applicable lapse restrictions as of the Effective Time and shall, as of the Effective Time, be canceled and converted into the right to receive the Merger Consideration in accordance with Section 2.01(a).

(b) As of the Effective Time, except as otherwise agreed by Parent and a holder of RSUs with respect to such holder's RSUs, each award of RSUs which is outstanding immediately prior to the Effective Time shall vest in full and become free of applicable lapse restrictions as of the Effective Time and shall, as of the Effective Time, be canceled and extinguished, and the holder thereof shall be entitled to receive an amount in cash equal to (i) the product of (A) the number of shares previously subject to such RSU and (B) the Merger Consideration, and the (ii) the value of any deemed dividend equivalents accrued but unpaid with respect to such RSUs, less any amounts required to be withheld under any applicable Law. All payments with respect to canceled RSUs shall be made by the Paying Agent (or such other agent reasonably acceptable to Parent as the Company shall designate prior to the Effective Time, which may be the Company's payroll agent) as promptly as reasonably practicable after the Effective Time from funds deposited by or at the direction of the Surviving Corporation to pay such amounts in accordance with Section 2.02(a).

SECTION 2.06 Dissenting Shares. (a) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, Shares that are outstanding immediately prior to

A-5

the Effective Time and that are held by any stockholder who is entitled to demand and properly demands (and does not timely withdraw such demand) the appraisal of such Shares (the "Dissenting Shares") pursuant to, and who complies in all respects with, the provisions of Section 262 shall not be converted into, or represent the right to receive, the Merger Consideration. Any such stockholder shall instead be entitled to receive payment of the fair value of such stockholder's Dissenting Shares in accordance with the provisions of Section 262; provided, however, that all Dissenting Shares held by any stockholder who shall have failed to perfect or who otherwise shall have withdrawn, in accordance with Section 262, or lost such stockholder's rights to appraisal of such Shares under Section 262 shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender of the Certificate or Certificates that formerly evidenced such Shares in the manner provided in Section 2.02(b), and the Surviving Corporation shall remain liable for the payment thereof.

(b) The Company shall give Parent (i) prompt notice of any demands received by the Company for appraisal of any Shares and withdrawals of such demands and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment or agree to make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

As of the date of this Agreement, no event has occurred which, with or without notice, lapse of time or both, would constitute a default or breach on the part of Parent under any term or condition of the Financing Commitments. As of the date of this Agreement, Parent has no reason to believe that it will be unable to satisfy on a timely basis any term or condition of closing to be satisfied by it contained in the Financing Commitments.

Within 24 hours of the Solicitation Period End Date, the Company shall notify Parent of the number of Excluded Parties and provide Parent a written summary of the material terms and conditions of each Acquisition Proposal received from any Excluded Party and, from and after the Solicitation Period End Date, keep Parent apprised as to the status and material developments, discussions and negotiations concerning the same on a current basis (and in any event no later than 24 hours after the occurrence of such developments, discussions or negotiations).

(d) Notwithstanding anything in this Agreement to the contrary, if, at any time prior to obtaining the Requisite Stockholder Vote, the Company receives an Acquisition Proposal which the Company Board (acting through, or based upon the advice of, the Special Committee if such committee still exists) concludes in good faith constitutes a Superior Proposal after giving effect to all of the adjustments which may be offered by Parent pursuant to clause (ii) below, the Company Board (acting through, or based upon the advice of, the Special Committee if such committee still exists) may (x) effect a Recommendation Withdrawal or (y) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal if, in the case of either the foregoing clauses (x) or (y), the Company Board (acting through, or based upon the advice of, the Special Committee if such committee still exists) determines in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable Law; provided, however that the Company shall not terminate this Agreement pursuant to the foregoing clause (y), and any purported termination pursuant to the foregoing clause (y) shall be void and of no force or effect, unless concurrently with such termination the Company pays the Termination Fee payable pursuant to Section 8.03(a); and provided, further, that the Company Board may not effect a Recommendation Withdrawal pursuant to the foregoing clause (x) or terminate this Agreement pursuant to the foregoing clause (y) unless:

(i) the Company shall have provided prior written notice to Parent and Merger Co, at least 72 hours in advance (the "Notice Period"), of its intention to effect a Recommendation Withdrawal in response to such Superior Proposal or terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal, which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal), and shall have contemporaneously provided a copy of the relevant proposed transaction agreements with the party making such Superior Proposal and other material documents; and

(ii) prior to effecting such Recommendation Withdrawal or terminating this Agreement to enter into a definitive agreement with respect to such Superior Proposal, the Company shall, and

A-29

shall cause its financial and legal advisors to, during the Notice Period, negotiate with Parent and Merger Co in good faith (to the extent Parent and Merger Co desire to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal.

In the event of any material revisions to the Superior Proposal, the Company shall be required to deliver a new written notice to Parent and Merger Co and to comply with the requirements of this Section 6.04(d) with respect to such new written notice.

(e) The Company agrees that any violations of the restrictions set forth in this Section 6.04 by any Company Representative shall be deemed to be a breach of this Section 6.04 by the Company.

(f) As used in this Agreement, the term:

(i) "Acquisition Proposal" means any inquiry, proposal or offer from any Person or group (other than Parent and its Affiliates) relating to any direct or indirect acquisition or purchase of 15% or more of the assets, net revenues or net income of the Company and its Subsidiaries, taken as a whole, or 15% or more of any class of equity securities of the Company then outstanding, any tender offer or exchange offer that if consummated would result in any Person beneficially owning 15% or more of any class of equity securities of the Company then outstanding, or any merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company (or any Subsidiary or Subsidiaries of the Company whose business constitutes 15% or more of the assets, net revenues or net income of the Company and its Subsidiaries, taken as a whole), other than as contemplated by this Agreement;

(ii) "Superior Proposal" means an Acquisition Proposal not solicited in violation of Section 6.04 that relates to an acquisition of more than 50% of the outstanding Shares or more than 50% of the assets, net revenues or income of the Company and its Subsidiaries, taken as a whole, that the Board of Directors of the Company (acting through, or based upon the advice of, the Special Committee, if such committee still exists) in good faith determines, would, if consummated, result in a transaction that is more favorable from a financial point of view to the stockholders of the Company than the transactions contemplated hereby (x) after receiving the advice of SunTrust, or another nationally recognized financial advisor, (y) after taking into account the likelihood of consummation of such transaction on the terms set forth therein (as compared to the terms herein, as may be adjusted pursuant to Section 6.04(d)(ii)) and (z) after taking into account all appropriate legal (with the advice of outside counsel), financial (including the financing terms of any such proposal), regulatory or other aspects of such proposal.

(g) Nothing contained in this Section 6.04 or elsewhere in this Agreement shall prohibit the Company from taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or 14e-2(a) promulgated under the Exchange Act; provided, any such disclosure (other than (i) a "stop, look and listen" letter or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act, (ii) a statement that the Company is unable to take a position with respect to the relevant tender offer (a "No-Position Statement") or (iii) a rejection by the Company of the relevant tender offer) shall be subject to compliance by the Company with Section 6.04(d) and shall be deemed to be a Recommendation Withdrawal; provided that if the Company makes a No-Position Statement and the Company Board does not expressly publicly reaffirm the Recommendation at least four business days prior to the Company Stockholders' Meeting, such No-Position Statement shall be deemed a Recommendation Withdrawal.

SECTION 6.05 Directors' and Officers' Indemnification and Insurance. (a) For a period of six years after the Effective Time, unless otherwise required by applicable Law, the certificate of incorporation and bylaws (or equivalent organizational documents) of the Surviving Corporation and its Subsidiaries shall contain provisions no less favorable with respect to the indemnification of and

A-30

advancement of expenses to directors and officers than are set forth in the Certificate of Incorporation or Bylaws (or equivalent organizational documents) of the Company (or the relevant Subsidiary) as in effect on the date hereof. Parent shall and shall cause the Surviving Corporation to indemnify, and advance expenses to, each present and former director or officer of the Company and each Subsidiary (collectively, the "Indemnified Parties"), in and to the extent of their capacities as such and not as stockholders of the Company or any Subsidiary, in respect of actions, omissions or events through the Effective Time to the fullest extent permitted by Law. Without limiting the generality of the preceding sentence, if any Indemnified Party becomes involved in any actual or threatened action, suit, claim, proceeding or investigation covered by this Section 6.05 after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, to the fullest extent permitted by Law, promptly advance to such Indemnified Party his or her legal or other expenses (including the cost of any investigation and preparation incurred in connection therewith). Parent shall, and shall cause the Surviving Corporation to, honor and perform under all indemnification agreements entered into by the Company or any of its Subsidiaries prior to the date hereof, true and complete copies of which have been made available to Parent.

(b) The Surviving Corporation shall either (i) cause to be obtained and shall maintain a "tail" insurance policy with a claims period of at least six years from the Effective Time with respect to directors' and officers' liability insurance in amount and scope, and with other material terms and conditions, at least as favorable as the Company's existing policies for claims arising from facts or events that occurred prior to the Effective Time or (ii) maintain the existing officers' and directors' liability insurance policies maintained by the Company (provided that the Surviving Corporation may substitute therefor policies of at least the same coverage containing terms and conditions that are not less favorable to the Indemnified Parties) for a period of six years after the Effective Time so long as the annual premium therefor is not in excess of 300% of the last annual premium paid prior to the date hereof; provided, however, that if the existing officers' and directors' liability insurance policies expire, are terminated or cancelled during such six-year period or require an annual premium in excess of 300% of the current premium paid by the Company for such insurance, the Company will obtain as much coverage as can be obtained for the remainder of such period for a premium not in excess of 300% (on an annualized basis) of such current premium.

(c) This Section 6.05 shall survive the consummation of the Merger and is intended to be for the benefit of, and shall be enforceable by, present or former directors or officers of the Company or its Subsidiaries, their respective heirs and personal representatives and shall be binding on the Surviving Corporation and its successors and assigns. If Parent or the Surviving Corporation or any of its successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or shall cease to continue to exist for any reason or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity (including by dissolution), then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation and the transferee or transferees of such properties and assets, as applicable, shall assume all of the obligations set forth in this Section 6.05. The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any such present or former director or officer is entitled, whether pursuant to Law, contract or otherwise. Nothing in this Agreement is intended to, shall be construed to, or shall, release, waive or impair any rights to directors' and officers' insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 6.05 is not prior to or in substitution for any such claims under any such policies.

SECTION 6.06 Employee Benefits Matters. (a) Parent hereby agrees that, for a period of one year after the Effective Time, it shall, or it shall cause the Surviving Corporation and its Subsidiaries to, (i) provide each employee of the Company and the Subsidiaries as of the Effective Time (each, an "Employee"), with (x) base salary and incentive compensation opportunities (other than equity-based compensation) that are substantially comparable in the aggregate to those provided to such Employees immediately prior to the Effective Time, and (y) employee benefits (other than equity-based compensation) that are substantially comparable in the aggregate to those provided to such Employees immediately prior to the Effective Time under the Plans listed on Section 3.11(a) of the Company Disclosure Schedule, taking into account changes pursuant to Section 5.01(g). Nothing herein shall be deemed to be a guarantee of employment for any Employee, or to restrict the right of the Surviving Corporation to terminate any Employee. Notwithstanding the foregoing, nothing contained herein, whether express or implied, (i) shall be treated as an amendment or other modification of any Employee Plan, or (ii) shall limit the right of the Surviving Corporation or any of its Subsidiaries to amend, terminate or otherwise modify any Employee Plan following the Closing Date. Parent, Merger Co and the Company acknowledge and agree that all provisions contained in this Section 6.06 with respect to Employees are included for the sole benefit of Parent, Merger Co and the Company, and that nothing herein, whether express or implied, shall create any third party beneficiary or other rights (i) in any other Person, including, without limitation, any Employees, former Employees, any participant in any Employee Plan, or any dependent or beneficiary thereof, or (ii) to continued employment with Parent, the Surviving Corporation, or any of their respective Affiliates or continued participation in any Employee Plan.

(b) Employees shall receive credit for their services with the Company and any of its Subsidiaries (including for purposes of eligibility to participate, vesting, benefit accrual and eligibility to receive benefits, but excluding benefit accruals under any defined benefit pension plan) under any employee benefit plan, program or arrangement established or maintained by Parent, the Surviving Corporation or any of their respective subsidiaries under which each Employee may be eligible to participate on or after the Effective Time to the same extent recognized by the Company or any of the Subsidiaries under comparable Plans immediately prior to the Effective Time; provided, however, that such crediting of service shall not operate to duplicate any benefit or the funding of any such benefit.

(c) With respect to the welfare benefit plans, programs and arrangements maintained, sponsored or contributed to by Parent or the Surviving Corporation ("Purchaser Welfare Benefit Plans") in which an active Employee may become eligible to participate in the one-year period following the Effective Time, Parent shall (i) waive, or use reasonable best efforts to cause its insurance carrier to waive, all limitations as to preexisting and at-work conditions, if any, with respect to participation and coverage requirements applicable to each active Employee under any Purchaser Welfare Benefit Plan to the same extent waived under a comparable Plan and (ii) use reasonable best efforts to cause any eligible expenses incurred by any Employee and his or her covered dependents under comparable Plans during the plan year in which such individuals move to a comparable Purchaser Welfare Benefit Plan to be taken into account under the Purchaser Welfare Benefit Plans for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Employee and his or her dependents as if such amounts had been paid in accordance with the Purchaser Welfare Benefit Plans.

(d) Company ESPP. On and after the date hereof, no future offering periods will be commenced or options will be granted under the ESPP. The Company shall terminate the current offering periods and options outstanding under the ESPP on the date of this Agreement and the Company shall terminate the ESPP immediately prior to the Effective Time. With respect to matters described in this Section 6.06(d), any material notices or other communication materials provided to the ESPP's participants shall be provided reasonably in advance to Parent and the Company shall take into consideration in good faith Parent's comments that are provided in writing.

A-32

(e) For the avoidance of doubt, it is expressly agreed that the provisions of Section 9.06 shall apply to this Section 6.06. From and after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries, as applicable, to honor and perform, in accordance with their terms, the Plans listed on Schedule 6.06(e) of the Company Disclosure Schedule.

SECTION 6.07 Notification of Certain Matters. Subject to applicable Laws and the instructions of any Governmental Authority, each of the Company and Parent shall keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby, including promptly furnishing the other with copies of notices or other communications received by Parent or the Company, as the case may be, or any of its Subsidiaries, from any Governmental Authority with respect to the Merger and the other transactions contemplated by this Agreement. Between the date hereof and the Effective Time, the Company and Parent shall promptly notify each other orally and in writing of (i) the occurrence, or non-occurrence, of any event that, individually or in the aggregate, would reasonably be expected to cause any condition to the obligations of any party to effect the Merger and the other transactions contemplated by this Agreement not to be satisfied, (ii) the failure of such party to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which, individually or in the aggregate, would reasonably be expected to result in any condition to the obligations of any party to effect the Merger and the other transactions contemplated by this Agreement not to be satisfied or (iii) any communication received (A) from any Person alleging a consent of such Person is or may be required in connection with the transactions contemplated by this Agreement or (B) from any Governmental Authority in connection with the transactions contemplated by this Agreement; provided, however, that the delivery of any notice pursuant to this Section 6.07 shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to the date of this Agreement or otherwise limit or affect the remedies available hereunder to the party receiving such notice; and provided further that any failure to provide notice pursuant to this Section 6.07 shall not be deemed to be a breach of this Agreement for purposes of Sections 7.02(b) or 7.03(b) hereof.

SECTION 6.08 Financing. (a) Parent shall use its reasonable best efforts to arrange the Debt Financing as promptly as practicable taking into account the expected timing of the Marketing Period and the Expiration Date on the terms and conditions described in the Debt Commitment Letters (provided that Parent may replace or amend the Debt Commitment Letters so long as the terms (x) shall not expand upon the conditions precedent to the Debt Financing as set forth in the Debt Commitment Letters in any respect or (y) would not adversely affect the ability of Parent or Merger Co to consummate the transactions contemplated hereby or the likelihood of consummation of the transactions contemplated hereby or reasonably be expected to delay the Closing; and provided further, that in the event of any such amendment or replacement of the Debt Commitment Letters in accordance with the foregoing, the term "Debt Commitment Letters" as used herein shall be deemed to include the Debt Commitment Letters as so amended or replaced, and the term "Financing Commitment" as used herein shall be deemed to include the Equity Funding Letters and the revised Debt Commitment Letters), including using reasonable best efforts to (i) satisfy on a timely basis all terms, conditions, representations and warranties applicable to Parent set forth in the Debt Commitment Letters; (ii) negotiate and enter into definitive agreements with respect thereto on substantially the terms and conditions contemplated by the Debt Commitment Letters or on other terms acceptable to Parent (provided that such other terms (x) shall not expand upon the conditions precedent to the Debt Financing as set forth in the Debt Commitment Letters in any respect or (y) would not adversely affect the ability of Parent or Merger Co to consummate the transactions contemplated hereby or the likelihood of consummation of the transactions contemplated hereby or reasonably be expected to delay the Closing); and (iii) enforce its rights under the Debt Commitment Letters. Parent will furnish correct and complete copies of all such definitive agreements (including any fee letters but redacting any confidential terms contained therein) to the Company promptly upon their execution. If any portion of the Debt Financing becomes unavailable on the terms and conditions

A-33

contemplated in the Debt Commitment Letters, Parent shall use its reasonable best efforts to arrange to obtain alternative financing from alternative sources (on terms and conditions no less favorable to Parent with respect to conditions precedent to the Debt Financing (as determined in the reasonable judgment of Parent) than the terms and conditions as set forth in the Debt Commitment Letters) in an amount sufficient to consummate the transactions contemplated by this Agreement as promptly as practicable following the occurrence of such event giving rise to such unavailability, but in any event no later than five calendar days after the final day of the Marketing Period. Parent shall keep the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to arrange the Debt Financing. For purposes of this Agreement, "Marketing Period" shall mean the first period of 20 consecutive business days after the date hereof throughout which (A) Parent shall have the Required Financial Information (as defined below) that the Company is required to provide to Parent pursuant to Section 6.08(c), (B) the Company has made the Required Filings (as defined below) and (C) the conditions set forth in Section 7.01 shall be satisfied and nothing has occurred and no condition exists that would cause any of the conditions set forth in Sections 7.02(a), 7.02(b) or 7.02(d) to fail to be satisfied assuming the Closing were to be scheduled for any time during such 20 consecutive business day period; provided, that if the Marketing Period has not ended on or prior to December 15, 2006, the Marketing Period shall commence no earlier than January 2, 2007; and provided, further, that the "Marketing Period" shall not be deemed to have commenced if, prior to the completion of the Marketing Period, PricewaterhouseCoopers LLP shall have withdrawn its audit opinion with respect to any financial statements contained in the SEC Reports.

(b) The Company agrees to provide, and shall cause the Subsidiaries and shall use its reasonable best efforts to cause the Company Representatives to provide, such cooperation in connection with the arrangement of the Debt Financing (including, without limitation, the issuance of senior notes and/or senior subordinated notes contemplated by the Commitment Letters) as may be reasonably requested by Parent (provided that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and the Subsidiaries), including without limitation (i) participation in meetings, road shows, drafting sessions, rating agency presentations and due diligence sessions customary and necessary for the consummation of the Debt Financing on the terms described in the Debt Commitment Letters, (ii) (A) furnishing Parent and its financing sources with financial and other pertinent information regarding the Company as may be customary for transactions of the type contemplated by the Debt Commitment Letters and reasonably requested by Parent, including all financial statements and financial data of the type required by Regulation S-X and Regulation S-K and of type and form customarily included in private placements under Rule 144A under the Securities Act to consummate the offering of secured or unsecured senior or senior subordinated notes (the "Required Financial Information") and (B) filing such reports under the securities laws as may be customary for transactions of the type contemplated by the Debt Commitment Letters and reasonably requested by Parent (the "Required Filings"); providedthat the Company shall not be required to file any projections pursuant to this Section 6.08, (iii) assisting Parent and its financing sources in the preparation of (A) offering documents for any portion of the Debt Financing and (B) materials for rating agency presentations, (iv) cooperating with the marketing efforts of Parent and its financing sources for any of the Debt Financing, (v) providing and executing customary closing documents as may be reasonably requested by Parent, including a certificate of the chief financial officer of the Company with respect to solvency matters, (vi) executing and delivering any pledge and security documents and otherwise facilitating the pledging of collateral, and (vii) using reasonable best efforts to obtain consents of accountants for use of their reports in any materials relating to the Debt Financing, accountants' comfort letters, legal opinions, surveys and title insurance customary for transactions of the type contemplated by the Debt Commitment Letters and as reasonably requested by Parent. Parent shall, promptly upon request by the Company, reimburse the Company for all reasonable out-of-pocket costs incurred by the Company or the Subsidiaries in connection with such cooperation. Except to the extent disclosed to potential investors and lenders in connection with the Debt Financing, all non-public or

A-34

otherwise confidential information regarding the Company obtained by Parent, Merger Co or their Representatives pursuant to this Section 6.08(b) shall be kept confidential in accordance with the Confidentiality Agreements.

SECTION 6.09 Further Action; Reasonable Best Efforts.

(g) Subject to the terms and conditions of this Agreement, each party will use its reasonable best efforts to take, or cause to be taken, all actions to file, or cause to be filed, all documents and to do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated by this Agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, consents, waivers, approvals, authorizations, permits or orders from all Governmental Authorities or other Persons. In furtherance and not in limitation of the foregoing, each party hereto agrees to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated by this Agreement as promptly as practicable after the date hereof and to make, or cause to be made, the filings and authorizations, if any, required under the Other Antitrust Laws of jurisdictions other than the United States as promptly as reasonably practicable after the date hereof and to supply as promptly as reasonably practicable any additional information and documentary material that may be requested pursuant to the HSR Act or the Other Antitrust Laws of jurisdictions other than the United States and use its reasonable best efforts to take or cause to be taken all other actions necessary, proper or advisable consistent with this Section 6.09 to cause the expiration or termination of the applicable waiting periods, or receipt of required authorizations, as applicable, under the HSR Act or the Other Antitrust Laws of jurisdictions other than the United States as soon as practicable. Without limiting the foregoing, the parties shall request and shall use reasonable best efforts to obtain early termination of the waiting period under the HSR Act.

(h) Each of Parent and Merger Co, on the one hand, and the Company, on the other hand, shall, in connection with the efforts referenced in Section 6.09(a), obtain all requisite approvals and authorizations for the transactions contemplated by this Agreement, use its reasonable best efforts to (i) cooperate in all respects with each other in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party; (ii) keep the other party reasonably informed of any communication received by such party from, or given by such party to, the Federal Trade Commission (the "FTC"), the Antitrust Division of the Department of Justice (the "DOJ") or any other Governmental Authority and of any communication received or given in connection with any proceeding by a private party, in each case regarding any of the transactions contemplated hereby; and (iii) permit the other party to review any communication given by it to, and consult with each other in advance of any meeting or conference with, the FTC, the DOJ or any other Governmental Authority or, in connection with any proceeding by a private party, with any other person, and to the extent permitted by the FTC, the DOJ or such other applicable Governmental Authority or other Person, give the other party the opportunity to attend and participate in such meetings and conferences.

(i) In furtherance and not in limitation of the covenants of the parties contained in Sections 6.09(a) and (b), if any objections are asserted with respect to the transactions contemplated hereby under any Law or if any suit is instituted (or threatened to be instituted) by the FTC, the DOJ or any other applicable Governmental Authority or any private party challenging any of the transactions contemplated hereby as violative of any Law or which would otherwise prevent, materially impede or materially delay the consummation of the transactions contemplated hereby, each of Parent, Merger Co and the Company shall use its reasonable best efforts to resolve any such objections or suits so as to permit consummation of the transactions contemplated by this Agreement, including in order to resolve such objections or suits which, in any case if not resolved, would reasonably be expected to prevent, materially impede or materially delay the consummation of the Merger or the other transactions contemplated hereby; provided, however, that no party shall be required to, and the Company may not

A-35

(without the prior written consent of Parent) take any such actions to resolve any such objections or suits which actions would reasonably be expected, individually or in the aggregate, to have a Company Material Adverse Effect.

(j) Subject to the obligations under Section 6.09(c), in the event that any administrative or judicial action or proceeding is instituted (or threatened to be instituted) by a Governmental Authority or private party challenging the Merger or any other transaction contemplated by this Agreement, or any other agreement contemplated hereby, each of Parent, Merger Co and the Company shall cooperate in all respects with each other and use its respective reasonable best efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement.

SECTION 6.10 Public Announcements. The initial press release relating to this Agreement shall be a joint press release the text of which has been agreed to by each of Parent and the Company. Thereafter, except with respect to any Recommendation Withdrawal or any action taken pursuant to, and in accordance with, Section 6.04 or Article VIII, so long as this Agreement is in effect, each of Parent and the Company shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or the Merger, except to the extent public disclosure is required by applicable Law or the requirements of the NASDAQ National Market, in which case the issuing party shall use its reasonable best efforts to consult with the other party before issuing any such release or making any such public statement.

SECTION 6.11 Resignations. The Company shall use its reasonable best efforts to obtain and deliver to Parent at the Closing evidence reasonably satisfactory to Parent of the resignation effective as of the Effective Time, of those directors of the Company or any Subsidiary designated by Parent to the Company in writing at least ten business days prior to the Closing.

SECTION 6.12 Debt Tender and Consent Solicitation. (a) As promptly as reasonably practicable after the request of Parent, the Company shall commence a Consent Solicitation and/or tender offer for all of the outstanding Convertible Notes (the "Debt Tender Offer"), or shall cooperate with Parent in connection with a Consent Solicitation and/or Debt Tender Offer by Parent or Merger Co, in each case on such reasonable terms and conditions as may be proposed from time to time by Parent. Notwithstanding anything herein to the contrary, the Consent Solicitation and/or Debt Tender Offer shall not require any payment for the Convertible Notes and/or the consents under the Consent Solicitation to be made prior to the Effective Time. Parent and Merger Co shall assist the Company in connection with any Consent Solicitation or Debt Tender Offer commenced by the Company upon the request of Parent hereunder.

(b) In connection with any Consent Solicitation or Debt Tender Offer commenced by the Company upon the request of Parent hereunder, the Company shall prepare all necessary and appropriate documentation, including the offer to purchase, the terms of the consent, related letters of transmittal and other related documents and any Schedule TO or other filing with the SEC (collectively, the "Offer Documents"). All mailings to the holders of the Convertible Notes in connection with the Consent Solicitation or Debt Tender Offer or related filings with the SEC shall be subject to the prior review and comment by each of the Company and Parent and shall be reasonably acceptable to each of them. Each of Parent, Merger Co and the Company shall cooperate, and the Company shall cause its Subsidiaries to cooperate, and each of Parent, Merger Co and the Company shall use its reasonable best efforts to cause its respective representatives to cooperate with each other in connection with any such Consent Solicitation or Debt Tender Offer (including the preparation of the Offer Documents) and use reasonable best efforts to cause the payment for any Consent or the initial settlement of the Debt Tender Offer to occur simultaneously with the Effective Time.

A-36

(c) Upon the request of Parent, the Company shall use its reasonable best efforts to obtain the Requested Consents. Promptly upon receipt of Requested Consents permitting an amendment of the indenture governing the Convertible Notes and upon the request of Parent, the Company shall enter into a supplemental indenture reflecting the amendments to such indenture approved by such Requested Consents and shall use its reasonable best efforts to cause the indenture trustee to promptly enter into such supplemental indenture; provided, that the amendments contained in such supplemental indenture shall become effective upon signing, but not operative until the Closing and, if applicable, the acceptance of the Debt Tender Offer. The closing of any Debt Tender Offer shall be conditioned on the simultaneous occurrence of the Closing. Simultaneously with the Closing and in accordance with the terms of any Consent Solicitation or Debt Tender Offer, if the Company shall have undertaken such Consent Solicitation or Debt Tender Offer, Parent or Merger Co shall provide the Company the funds necessary to consummate the Debt Tender Offer and/or Consent Solicitation (including the payment of all applicable premiums, consent fees and all related fees and expenses) and the Company, if applicable, shall accept for purchase and use such funds to purchase the Convertible Notes tendered in the Debt Tender Offer (the "Tendered Notes").

(d) If requested by Parent, the Company shall enter into one or more dealer manager agreements with such Persons as Parent shall reasonably request. Parent shall pay the reasonable fees and expenses of any dealer manager, information agent, depositary or other agent retained in connection with any Consent Solicitation or Debt Tender Offer.

(k) At Parent's request, the Company shall cooperate with Parent in causing the satisfaction and discharge and/or covenant defeasance provisions of the Convertible Notes and the indenture pursuant to which they were issued to be satisfied on the date of the Closing; provided that Parent shall have sole responsibility for making any payments to the trustee and otherwise satisfying the requirements and conditions that must be satisfied in connection therewith. Parent shall pay all costs incurred in connection with such satisfaction and discharge or covenant defeasance, including the reasonable fees and expenses of the Company's outside counsel, accountants and/or financial advisors to the extent that Parent requests one or more of them to prepare or deliver any documentation required in connection therewith.

SECTION 8.03 Fees and Expenses.

(l) In the event that this Agreement is terminated by the Company pursuant to Section 8.01(g) or by Parent pursuant to Section 8.01(i), then the Company shall pay the Termination Fee as directed in writing by Parent, at or prior to the time of termination in the case of a termination pursuant to Section 8.01(g) or as promptly as possible (but in any event within two business days) following termination of this Agreement in the case of a termination pursuant to Section 8.01(i).

A-40

Company and its Subsidiaries, taken as a whole, involving a Person or an Affiliate of a Person that entered into a confidentiality agreement with respect to the Company or any of the Subsidiaries prior to such termination, then, in the case of each of clauses (i) and (ii), on the date of such execution or consummation, the Company shall pay the Termination Fee as directed in writing to Parent, less the amount of any Parent Expenses previously paid to Parent by the Company.

(c) In the event that this Agreement is terminated by Parent or the Company pursuant to Section 8.01(f) (or is terminated by the Company pursuant to a different section of Section 8.01 at a time when this Agreement was terminable pursuant to Section 8.01(f)) or by Parent pursuant to Section 8.01(d) (or is terminated by the Company pursuant to a different section of Section 8.01 hereof at a time when this Agreement was terminable pursuant to Section 8.01(d)) under circumstances in which the Termination Fee is not yet payable pursuant to this Section 8.03, then the Company shall pay as promptly as possible (but in any event within two business days) following receipt of an invoice therefor all of Parent's actual and reasonably documented out-of-pocket fees and expenses (including reasonable legal fees and expenses) actually incurred by Parent and its Affiliates on or prior to the termination of this Agreement in connection with the transactions contemplated by this Agreement ("Parent Expenses") as directed by Parent in writing, which amount shall not be greater than $5,000,000; provided, that the existence of circumstances which could require the Termination Fee to become subsequently payable by the Company pursuant to Section 8.03(b) shall not relieve the Company of its obligations to pay the Parent Expenses pursuant to this Section 8.03(c); and provided, further that the payment by the Company of Parent Expenses pursuant to this Section 8.03(c) shall not relieve the Company of any subsequent obligation to pay the Termination Fee pursuant to Section 8.03(b) except to the extent indicated in Section 8.03(b).

(d) In the event that this Agreement is terminated by the Company pursuant to (i) Section 8.01(h) or (ii) Section 8.01(e) and at the time of such termination there is no state of facts or circumstances that would reasonably be expected to cause the conditions set forth in Section 7.01, 7.02(a), 7.02(b) and 7.02(d) not to be satisfied on or prior to the Expiration Date, then Parent shall pay the Company the Termination Fee as promptly as possible (but in any event within two business days) following such termination by the Company.

(e) Any amount that becomes payable pursuant to Section 8.03(a), 8.03(b) or 8.03(c) or 8.03(d) shall be paid by wire transfer of immediately available funds to an account designated by the party entitled to receive such payment.

(f) Each of the Company, Parent and Merger Co acknowledges that the agreements contained in this Section 8.03 are an integral part of the transactions contemplated by this Agreement, that without these agreements the Company, Parent and Merger Co would not have entered into this Agreement, and that any amounts payable pursuant to this Section 8.03 do not constitute a penalty.

Notwithstanding anything to the contrary in this Agreement, the Company's right to receive payment of the Termination Fee from Parent pursuant to this Section 8.03 or the guarantee thereof pursuant to the Guarantees shall be the sole and exclusive remedy of the Company and its Subsidiaries against Parent, Merger Co, the Guarantors and any of their respective former, current, or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates or agents (or any of the former, current,

A-41

or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates or agents of any of the foregoing) for the loss suffered as a result of the failure of the Merger to be consummated, the termination of this Agreement, the failure to consummate the transactions contemplated by this Agreement and any claims or Actions under applicable Law arising out of any breach, termination or failure of or under this Agreement, and upon payment of such amount, none of Parent, Merger Co, the Guarantors or any of their respective former, current, or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates or agents (or any of the former, current, or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates or agents of any of the foregoing) shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement.

(g) Except as otherwise set forth in this Section 8.03, or in Sections 6.08 and 6.12, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such costs or expenses.

This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

SECTION 8.05 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any obligation or other act of any other party hereto, (b) waive any inaccuracy in the representations and warranties of any other party contained herein or in any document delivered pursuant hereto and (c) subject to the requirements of applicable Law, waive compliance with any agreement of any other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby.

(c) When a reference is made in this Agreement to Sections, Schedules or Exhibits, such reference shall be to a Section, Schedule or Exhibit of this Agreement, respectively, unless otherwise indicated. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation". Unless otherwise specified, the words "hereof," "herein" and "hereunder" and words of similar import when used in this Agreement shall refer to this Agreement as a whole (including the Company Disclosure Schedule and Exhibits) and not any particular provision of this Agreement. The term "or" is not exclusive. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Unless otherwise expressly defined, terms defined in this Agreement have the same meanings when used in any Exhibit or Schedule hereto, including the Company Disclosure Schedule. References to a Person are also to its permitted successors and assigns. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The word "extent" in the phrase "to the extent" shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply "if". References to a Person are also to its permitted successors and assigns.

SECTION 9.04 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect

A-49

the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

SECTION 9.05 Entire Agreement; Assignment. This Agreement, the Guarantees and the Confidentiality Agreements constitute the entire agreement among the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, among the parties hereto, or any of them, with respect to the subject matter hereof and thereof. No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of the other parties hereto (and any purported assignment without such consent shall be void and without effect), except that each of Parent and Merger Co may assign all or any of its rights and obligations hereunder to any Affiliate of Parent or, after the Closing, in connection with a merger, consolidation or sale of all or substantially all of the assets of Parent or the Surviving Corporation and its Subsidiaries; provided, however, that no such assignment shall relieve the assigning party of its obligations hereunder if such assignee does not perform such obligations.

SECTION 9.06 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 6.05 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons).

SECTION 9.07 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware (without giving effect to the choice of law principles therein).

SECTION 9.08 Specific Performance; Submission to Jurisdiction. (a) The Company agrees that to the extent it has incurred losses or damages in connection with this Agreement, (i) the maximum aggregate liability of Parent and Merger Co for such losses or damages shall be limited to $30,000,000, (ii) the maximum liability of the Guarantors, directly or indirectly, shall be limited to the express obligations of the Guarantors under the Guarantees, and (iii) in no event shall the Company seek to recover any money damages in excess of such amount from Parent, Merger Co or the Guarantors or any of their respective stockholders, partners, members, affiliates, directors, officers, employees or agents in connection therewith.

(b) The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by the Company in accordance with their specific terms or were otherwise breached. It is accordingly agreed that Parent and Merger Co shall, prior to the termination of this Agreement pursuant to Section 8.01, be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in Court of Chancery or other courts of the State of Delaware, this being in addition to any other remedy to which such party is entitled at law or in equity, subject to the limitations in paragraph (a) of this Section 9.08. The parties acknowledge that the Company shall not be entitled to an injunction or injunctions to prevent breaches of this Agreement by Parent or Merger Co or to enforce specifically the terms and provisions of this Agreement and that the Company's sole and exclusive remedy with respect to any such breach shall be the remedy set forth in Section 8.03(d) and Section 9.08(a); provided that the Company shall be entitled to specific performance against Parent and Merger Co to prevent any breach by Parent or Merger Co of Section 6.03(b) and the last sentence of Section 6.08(b).

(c) Each of the parties hereto (i) consents to submit itself to the personal jurisdiction of the Court of Chancery or other courts of the State of Delaware in the event any dispute arises out of this Agreement or any of the transactions contemplated by this Agreement, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from such court, (iii) agrees that it will not bring any action relating to this Agreement or any of the transactions

A-50

contemplated by this Agreement in any court other than the Court of Chancery or other courts of the State of Delaware and (iv) to the fullest extent permitted by Law, consents to service being made through the notice procedures set forth in Section 9.02. Each party hereto hereby agrees that, to the fullest extent permitted by Law, service of any process, summons, notice or document by U.S. registered mail to the respective addresses set forth in Section 9.02 shall be effective service of process for any suit or proceeding in connection with this Agreement or the transactions contemplated hereby.

SECTION 9.09 Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the Merger. Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement and the Merger, as applicable, by, among other things, the mutual waivers and certifications in this Section 9.09.

SECTION 9.10 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 9.11 Counterparts. This Agreement may be executed and delivered (including by facsimile or other electronic transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Special Committee of the Board of Directors
Open Solutions, Inc.
455 Winding Brook Drive
Glastonbury, CT 06033

Gentlemen:

We understand that Open Solutions, Inc. (the "Company") is considering a transaction (the "Transaction") whereby the Company will be acquired by a newly formed acquisition corporation (the "Acquiring Party") for cash consideration of $38.00 per share of the Company's common stock (the "Merger Consideration"). Pursuant to the terms and conditions of the Agreement and Plan of Merger (the "Agreement") and various other related agreements, we further understand that the Acquiring Party will be principally capitalized by: 1) cash equity contributions made jointly by Carlyle Partners IV, L.P. ("Carlyle"), Providence Equity Partners V L.P. ("PEPV") and Providence Equity Partners V-A L.P. (together with PEPV, "Providence"); 2) a roll-over contribution of current equity ownership in the Company by certain of the Company's existing senior management; and 3) the proceeds of various senior and subordinated debt financings.

We have been requested by the Special Committee of the Board of Directors of the Company (the "Special Committee") to render to it our opinion with respect to the fairness, from a financial point of view, of the Merger Consideration to the holders of the Company's common stock.

In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and certain other agreements related to the Transaction, including the equity commitment letters and related guarantees provided by Carlyle and Providence; (2) publicly available information concerning the Company which we believe to be relevant to our inquiry; (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company; (4) the trading history of the Company's common stock from November 2003 to present and a comparison of that trading history with those of other publicly traded companies which we deemed relevant; (5) a comparison of the historical financial results and present financial condition of the Company with those of publicly traded companies which we deemed relevant; (6) historical data relating to percentage premiums paid in acquisitions of publicly traded companies from November 2005 to the present; and (7) a comparison of the financial terms of the Transaction with the publicly available financial terms of certain other recent transactions which we deemed relevant. In addition, we have had discussions with the management of the Company concerning the Company's business, operations, assets, present condition and future prospects and undertook such other studies, analyses and investigations as we deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information discussed with or reviewed by us in arriving at our opinion. With respect to the financial forecasts of the Company provided to or discussed with us, we have assumed, at the direction of the Special Committee and without independent verification or investigation, that such forecasts have been reasonably prepared on bases reflecting the best currently available information, estimates and judgments of the management of the Company as to the future financial performance of the Company. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made nor obtained any

B-1

evaluations or appraisals of the assets or liabilities (including, without limitation, any potential environmental liabilities), contingent or otherwise, of the Company. We have also assumed that the Transaction will be consummated in accordance with the terms of the Agreement and related agreements. We have also assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or on the expected benefits of the Transaction. Our opinion is necessarily based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. We express no opinion as to the underlying valuation, future performance or long-term viability of the Company. It should be understood that, although subsequent developments may affect this opinion, we do not have any obligation to update or revise the opinion.

We have acted as financial advisor to the Special Committee in connection with the Transaction and will receive a fee for our services, a portion of which is contingent upon the consummation of the Transaction at per share price in excess of the Merger Consideration, as set forth in the engagement letter entered into with the Special Committee in connection with the Transaction. In addition, the Company has agreed to indemnify us for certain liabilities arising out of the rendering of this opinion. In the ordinary course of our business, we and our affiliates actively trade in the equity securities of the Company for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. In addition, we and our affiliates (including SunTrust Banks, Inc.) may in the future have other financing and business relationships with the Company in the ordinary course of business.

Based upon and subject to the foregoing, and such other factors as we deemed relevant, we are of the opinion as of the date hereof that, from a financial point of view, the Merger Consideration to be received in the Transaction is fair to the Company's stockholders. This opinion is being rendered at the behest of the Special Committee and is for the benefit of the Special Committee in its evaluation of the Transaction and may not be used for any other purpose without our prior written consent. This opinion may be reproduced in full or referred to in any proxy or information statement mailed to stockholders of the Company in connection with the Transaction if required by applicable law but may not otherwise be disclosed publicly in any manner without our prior approval. This opinion does not constitute a recommendation as to how any stockholder should act or vote with respect to any matters relating to the Transaction.

		Very Truly Yours,
		/s/ SUNTRUST CAPITAL MARKETS, INC. SUNTRUST CAPITAL MARKETS, INC.

Annex C

Delaware General Corporation Law

§ 262. Appraisal rights

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of § 251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to § § 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

C-1

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the

C-2

stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial

C-3

upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
