Unless otherwise indicated, all information in this Proxy Statement and each Proposal ("Proposal") applies separately to each Trust. This Proxy Statement and the accompanying letter to shareholders from the Chairman of the Board of Trustees, Notice of Annual Meeting of Shareholders, and proxy card(s) are being mailed on or about March 4, 2011, to shareholders of record on February 14, 2011, the record date. Each Trust's principal business office is c/o Babson Capital Management LLC ("Babson Capital"), 1500 Main Street, P.O. Box 15189, Springfield, Massachusetts 01115-5189. Holders of the shares of beneficial interest of each Trust ("shares") of record at the close of business on February 14, 2011 will be entitled to one vote per share on all business of the Meeting and any adjournments. There were 9,476,093 shares of MCI outstanding and 10,065,356 shares of MPV outstanding on the record date. The Trusts, to the best of their knowledge, are not aware of any beneficial owner of more than 5% of the outstanding shares of each Trust. However, MassMutual, the ultimate parent company of Babson Capital, may be deemed a beneficial owner of more than 5% of the outstanding shares of MCI by reason of it owning a $30,000,000 Senior Fixed Rate Convertible Note due November 15, 2017 (the "MCI Note") issued by the Trust. Similarly, MassMutual may be deemed a beneficial owner of more than 5% of the outstanding shares of MPV by reason of it owning a $12,000,000 Senior Fixed Rate Convertible Note due December 13, 2011 (the "MPV Note" and, together with "MCI Note" each a "Note" and collectively the "Notes"). MassMutual, at its option, can convert the principal amount of each Note into shares. The dollar amount of principal would be converted into an equivalent dollar amount of shares based upon the average price of the shares for ten business days prior to the notice of conversion. Any person giving a proxy has power to revoke it by mail or in person at any time prior to its exercise by executing a superseding proxy or by submitting a notice of revocation to the Trust. All properly executed and unrevoked proxies received in time for the Meeting will be voted in accordance with the instructions contained therein. 3 Pursuant to the By-Laws of each Trust, the presence at the Annual Meeting, in person or by proxy, of shareholders entitled to cast a majority of the votes shall be a quorum for the transaction of business. A plurality of votes cast is required to elect Trustees. Thus, for each Trust, the three nominees for election at the Annual Meeting who receive the greatest number of votes properly cast for the election of Trustees shall be elected Trustees. Votes cast by proxy or in person at the Annual Meeting will be counted by persons appointed by each Trust to act as election inspectors for the Meeting. The election inspectors will count the total number of votes cast "for" approval of the Proposals for purposes of determining whether sufficient affirmative votes have been cast. The election inspectors will count shares represented by proxies that withhold authority to vote for a nominee for election as a Trustee or that reflect abstentions or "broker non-votes" (i.e., shares held by brokers or nominees as to which (i) instructions have not been received from the beneficial owners or the persons entitled to vote and (ii) the broker or nominee does not exercise the discretionary voting power on a particular matter) as shares that are present and entitled to vote on the matter for purposes of determining the presence of a quorum. With respect to the election of Trustees, abstentions and broker non-votes have no effect on the outcome of the Proposal so long as a quorum is present.

The officers were last elected on July 21, 2010. position(s) 14 The following provides an overview of the considerations that led each Board to conclude that each individual serving as a Trustee of each Trust should so serve. The current members of each Board have joined the Board at different points in time since 1986. Generally, no one factor was decisive in the original selection of an individual to join each Board. Among the attributes common to all Trustees is their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Trusts' investment adviser, counsel and independent auditors, and to exercise effective business judgment in the performance of their duties as Trustees. In recommending the election or appointment of the current Board members as Trustees, the Nominating Committee generally considered (i) the educational, business and professional experience of each individual; (ii) the individual's record of service as a director or trustee of public or private organizations; and (iii) how the individual's skills, experience and attributes would contribute to an appropriate mix of relevant skills and experience on the Board. The Nominating Committee also considered that during their service as members of the Boards of Trustees of the Trusts, the Trustees have demonstrated a high level of diligence and commitment to the interests of each Trust's shareholders and the ability to work effectively and collegially with other members of the Board. The following summarizes each Trustee's professional experience and additional considerations that contributed to each Board's conclusion that each individual should serve on the Board. MR. BARRETT - Mr. Barrett brings over 30 years of investment banking experience to each Board. Mr. Barrett is the President of WJ Barrett Associates, Inc., former President of Barrett-Gardner Associates, Inc., a private merchant bank and was a Senior Vice President with Janney Montgomery Scott LLC, a financial services firm, for over 26 years. Mr. Barrett has substantial board experience, having served on the boards of over 20 publicly traded companies. He has served as a Director of TGC Industries, Inc. since 1979, and also currently serves on the boards of Chase Packaging Corporation, Rumson-Fair Haven Bank and Trust Company, and Supreme Industries, Inc. MR. BENSON - Mr. Benson has extensive executive and board experience in the financial services industry. He has served as an Executive Vice President of Marquette Financial Companies since 1992 and a Partner of Benson Family Limited Partnership No. 1 and Benson Family Limited Partnership No. 2 (investment partnerships) since 1996. He serves as Vice President of CRP Sports, Inc. (the managing general partner of the Minnesota Twins baseball club). Mr. Benson also serves as a Director for First California Financial Group, Inc.

This information is based on information furnished by each Trustee and Officer. Beneficial ownership has been determined in accordance with Rule 16a-1(a)(2) under the Securities and Exchange Act of 1934, as amended (the "Exchange Act"). Also, as of January 20, 2011, Babson Capital, the investment adviser to each Trust, beneficially owned 0.87% of the outstanding shares of MCI and 1.42% of the outstanding shares of MPV. Members of each Board of Trustees historically have invested in one or both of the Trusts, as is consistent with their individual financial goals. In October 2010, this policy was formalized through adoption of a requirement that each Independent Trustee invest one year's worth of fees received for serving as trustee of the Trusts (excluding committee fees) in shares of one or both of the Trusts. Investments in the name of family members or entities controlled by a Trustee constitute Trust holdings of such Trustee for purposes of this policy, and a three-year phase-in period applies to such investment requirements for Trustees and newly elected Trustees. In implementing such policy, a Board member's Trust holdings existing on October 22, 2010, are valued as of such date with subsequent investments valued at cost. The table below sets forth information regarding the beneficial ownership* of each Trust's shares by each Trustee and the Officers beneficially owning shares based on the market value of such shares as of January 20, 2011.

As discussed below, three of the standing committees of the Board, to which the Board has delegated certain authority and oversight responsibilities, are comprised exclusively of Independent Trustees. Mr. Noreen, an "interested person" of each Trust, as defined in Section 2(a) (19) of the 1940 Act, serves as Chairman of each Board of Trustees. Mr. Noreen presides at meetings of each Board and acts as a liaison with service providers, officers, and other Trustees generally between meetings, and performs such other functions as may be requested by each Board from time to time. The Independent Trustees have not designated a lead Independent Trustee, but the Chairman of the Audit Committee, Mr. Benson, generally acts as chairman of meetings or executive sessions of the Independent Trustees, and when appropriate, represents the views of the Independent Trustees to management. The Board of each Trust reviews its leadership structure periodically and believes that the leadership structure is appropriate to enable each Board to exercise its oversight of each Trust. Each Board also believes that its structure, including the active role of the Independent Trustees, facilitates an efficient flow of information concerning the management of each Trust to the Independent Trustees. Each Board provides oversight of the services provided by Babson Capital, including risk management activities. In addition, each committee of each Board provides oversight of Babson Capital's risk activities with respect to the particular activities within the committee's purview. In the course of providing oversight, the Board and relevant committees for each Trust receive a wide range of reports on the Trusts' activities, including each Trust's investment portfolio, the compliance of the Trusts with applicable laws, and the Trusts' financial accounting and reporting. The Board and Audit Committee for each Trust meet periodically with the Trusts' Chief Compliance Officer regarding the compliance of the Trusts with federal securities laws and the Trusts' internal compliance policies and procedures. In addition, both the Audit Committee and the full Board of each Trust regularly review information and materials concerning risks specific to the Trusts and Babson Capital, including presentations by various officers of the Trusts, investment personnel for the Trusts, Babson Capital, Corporate Audit, the independent auditors for the Trusts (KMPG LLP) and Counsel to the Trusts. INFORMATION CONCERNING COMMITTEES AND MEETINGS OF THE BOARD OF TRUSTEES Each Board of Trustees has an Audit Committee, a Joint Transactions Committee, a Nominating Committee and a Governance Committee. The Audit Committee of each Trust is comprised exclusively of Trustees who are not "interested persons" of the Trust, as defined in Section 2(a)(19) of the 1940 Act, and operates pursuant to a written Audit Committee Charter, which is available on each Trust's website, www.babsoncapital.com/mci and www.babsoncapital.com/mpv. A print copy of the Audit Committee Charter may also be obtained by calling, toll-free, 1-866-399-1516. The present members of the Audit Committee of each Trust are Donald 18 E. Benson (Chairman), Michael H. Brown and Corine T. Norgaard. Each member of the Audit Committee qualifies as an "Independent Trustee" under the current listing standards of the New York Stock Exchange (the "Listing Standards") and the rules of the U.S. Securities and Exchange Commission ("SEC"). In accordance with the SEC's rules implementing Section 407 of the Sarbanes-Oxley Act of 2002 and upon due consideration of the qualifications of each member of each Trust's Audit Committee, each Board designated Mr. Benson as the Trust's Audit Committee Financial Expert. In accordance with the standards set forth in the Audit Committee Charter of each Trust, the Audit Committee is responsible for: oversight matters; financial statement and disclosure oversight matters; matters related to the hiring, retention, and oversight of the Trust's independent accountants; certain accounting and audit related oversight matters; and certain other matters as set forth in the Audit Committee Charter. During the twelve months ended December 31, 2010, the Audit Committee held eight meetings. The Joint Transactions Committee of each Trust is comprised of all Trustees who are not "interested persons" of the Trust, as defined in Section 2(a)(19) of the 1940 Act. This Committee reviews certain joint investment transactions between each Trust and MassMutual pursuant to the conditions set forth in the Trust's SEC exemptive order under Section 17(d) of the 1940 Act and Rule 17d-1 thereunder. This Committee acts primarily by written consent (fourteen consents were executed by Committee members, approving twenty-six investments and turning down zero investments during the past fiscal year). The Committee also met five times during the year in conjunction with meetings of each Trust's Board of Trustees (approving seven investments and turning down zero investments during the past fiscal year). The Governance Committee of each Trust is currently comprised of Robert E. Joyal (Chairman), William J. Barrett, Michael H. Brown, Donald Glickman and Maleyne M. Syracuse. The Governance Committee considers, evaluates and makes recommendations to the Board of Trustees of each Trust with respect to the structure, membership and function of the Board of Trustees and the Committees thereof, including the compensation of the Trustees. During the twelve months ended December 31, 2010, the Governance Committee held four meetings. The Nominating Committee of each Trust currently is comprised of all Independent Trustees and is chaired by Corine T. Norgaard. A current copy of each Trust's Nominating Committee's Charter can be found on each Trust's website, www.babsoncapital.com/mci and www.babsoncapital.com/mpv. This Committee met once during fiscal year 2010. The Nominating Committee is responsible for identifying and nominating individuals to serve as Trustees who are not "interested persons" of each Trust ("Independent Trustees"). The Nominating Committee Charter contemplates that all nominees for Independent Trustees have a college degree or, in the judgment of the Committee, equivalent business experience. In addition, the Committee may take into account a wide variety of factors in considering Trustee candidates, giving such weight to any individual factor(s) as it deems appropriate, including but not limited to: availability and commitment of a 19 candidate to attend meetings and perform his or her responsibilities on each Board; relevant industry and related experience; educational background; depth and breadth of financial expertise; and an assessment of the candidate's ability, judgment, expertise, reputation, and integrity. In the case of a shareholder recommended candidate, the Committee may also consider any other facts and circumstances attendant to such shareholder submission as may be deemed appropriate by the Committee. Different factors may assume greater or lesser significance at particular times, in light of the Board's present composition and the Committee's (or the Board's) perceptions about future issues and needs. When each Board has or expects to have a vacancy for an Independent Trustee, the Nominating Committee will consider candidates recommended by each Trust's current Trustees; each Trust's shareholders; each Trust's officers; each Trust's investment adviser; and any other source the Committee deems to be appropriate. Shareholder recommendations to fill vacancies on the Board for Independent Trustees must be submitted in accordance with the provisions of the Nominating Committee Charter, which requires that shareholder recommendations be timely received, and contain biographical and other necessary information regarding the candidate that would be required for the Trust to meet its disclosure obligations under the proxy rules. The Nominating Committee will evaluate nominee candidates properly submitted by shareholders in the same manner as it evaluates candidates recommended by other sources. During the past fiscal year, each Board of Trustees held five regular meetings (one of which was held by means of a telephone conference call). During the past fiscal year, each Trustee of each Trust attended all of the meetings of the Board of Trustees and all of the Committees of the Board on which s/he served. TRANSACTIONS WITH AND REMUNERATION OF OFFICERS AND TRUSTEES Pursuant to the Investment Services Contract between each Trust and Babson Capital (the "Contract"), Babson Capital paid the compensation and expenses of the Trusts' officers and of all Trustees of the Trusts who were officers or employees of Babson Capital. In April 2010, the Board reviewed the Trustee compensation structure and unanimously voted to approve an increase to certain fees paid to Trustees who are not officers or employees of Babson Capital. Trustees receive an annual retainer paid by MCI of $24,000 (an increase of $10,000) and by MPV of $16,000 (an increase of $6,000). Each Trust also pays an additional annual retainer fee to the Chairman of the Audit Committee in the amount of $3,000 (an increase of $500). Trustees of MCI also receive a fee of $3,000 (an increase of $750) and Trustees of MPV receive a fee of $2,000 (an increase of $500) for each meeting of each Board which they attend ($1,500 and $1,000 respectively for each meeting conducted by telephone conference call). Members of the Audit Committee, Nominating Committee and Governance Committee of each Trust receive an additional fee of $1,500 (an increase of $500) per meeting attended, including meetings conducted by telephone conference call. Pursuant to a deferred compensation plan, Trustees may defer receipt of their fees until their retirement from the Board or some other time at 20 their election. During the fiscal year ended December 31, 2010, the aggregate direct remuneration to these Trustees and reimbursement of their out-of-pocket expenses paid was approximately $303,728.55 for MCI and $220,453.52 for MPV. The following table discloses the compensation paid to each Trust's Trustees (not including reimbursement for out-of-pocket expenses) for the fiscal year ended December 31, 2010. The Trusts, MassMutual Premier Funds, MML Series Investment Fund, MassMutual Select Funds, and MML Series Investment Fund II are collectively referred to in the table below as the "Fund Complex". The Trustees do not receive pension or retirement benefits.

AUDIT COMMITTEE REPORT OF EACH TRUST Each Trust's Audit Committee oversees the Trust's financial reporting process on behalf of each Trust's Board of Trustees and operates under a written Charter adopted by each Trust's Board of Trustees. The Audit Committee meets with each Trust's management ("Management") and independent registered public accountants and reports the results of its activities to each Trust's Board of Trustees. Management has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. In connection with each Committee's and independent registered accountant's responsibilities, Management advised that each Trust's financial statements were prepared in conformity with generally accepted accounting principles. 21 Accordingly, each Trust's Audit Committee has: |X| Reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2010 with Management and KPMG LLP, each Trust's independent registered public accountants; |X| Discussed with KPMG LLP those matters required to be discussed by SAS 61 (Codification of Statements on Auditing Standards); and |X| Received the written disclosure and the letter from KPMG LLP required by the Public Company Accounting Oversight Board Rule 3526 (Communications with Audit Committee Concerning Independence) and has discussed with KPMG LLP its independence. Each Trust's Audit Committee has also reviewed the aggregate fees billed for professional services rendered by KPMG LLP for 2009 and 2010 for each Trust and for the non-audit services provided to Babson Capital, and Babson Capital's parent, MassMutual. As part of this review, the Audit Committee considered whether the provision of such non-audit services was compatible with maintaining the principal accountant's independence. In reliance on the reviews and discussions referred to above, each Trust's Audit Committee presents this Report to each Trust's Board of Trustees and recommends that each Trust's Board of Trustees (1) include the December 31, 2010 audited financial statements in the Annual Report to Shareholders for the fiscal year ended December 31, 2010, and (2) file such Annual Report with the Securities and Exchange Commission and the New York Stock Exchange. Each Trust's Audit Committee appointed the firm of KPMG LLP as the Trust's auditor for the fiscal year ending December 31, 2011, and, in connection therewith, KPMG LLP will prepare all of each Trust's tax returns for the fiscal year ending December 31, 2011. SUBMITTED BY THE AUDIT COMMITTEE OF EACH TRUST'S BOARD OF TRUSTEES Donald E. Benson, Audit Committee Chair Michael H. Brown, Audit Committee Member Corine T. Norgaard, Audit Committee Member FEBRUARY 16, 2011 Each Trust's Board of Trustees reviewed this Report and approved the audited financial statements for publication in each Trust's Annual Report. 22 THE TRUSTS' INDEPENDENT AUDITORS KPMG LLP ("KPMG") audited the financial statements of each Trust, Babson Capital, and MassMutual for the fiscal year ended December 31, 2010. KPMG's audit report for each Trust contained no qualifications or modifications. A KPMG representative is expected to be present at the upcoming Annual Meeting. This representative shall have the opportunity to make a statement if he or she desires to do so, and it is expected that such representative will be available to respond to appropriate questions from shareholders. As noted above, KPMG will audit each Trust's 2011 financial statements and prepare each Trust's 2011 Federal and state tax returns.

Preparation of Federal, state and local income tax returns and tax compliance work are representative of the fees reported in the "Tax Fees" category. The category "All Other Fees" represents fees billed by KPMG for consulting rendered to Babson Capital and MassMutual. The Sarbanes-Oxley Act of 2002 and its implementing regulations allows each Trust's Audit Committee to establish a pre-approval policy for certain services rendered by the Trust's independent accountants. During 2009, each Trust's Audit Committee approved all of the services rendered to the Trust by KPMG and did not rely on such a pre-approval policy for any such services. The 2009 fees billed represent final 2009 amounts, which may differ from the preliminary figures available as of the publication date of the Trusts' 2010 Proxy Statement and includes, among other things, fees for services that may not have been billed as of the publication date of the Trusts' 2010 Proxy Statement, but are now properly included in the 2009 fees billed to each Trust, Babson Capital and MassMutual. OTHER BUSINESS The Board of Trustees of each Trust knows of no business to be brought before the Meeting other than as set forth above. If, however, any other matters properly come before the Meeting, it is the intention of the persons named in the enclosed proxy card to vote proxies on such matters in accordance with their best judgment. INVESTMENT ADVISER Babson Capital provides investment management and certain administrative services to MCI pursuant to an Investment Services Contract and to MPV pursuant to an Investment Advisory and Administrative Services Contract. Babson Capital (including its wholly owned subsidiaries) currently has over $133 billion in assets under management and provides investment management services to registered investment companies, unregistered investment companies and institutional investors (such as insurance companies, pension plans, endowments and foundations). MassMutual Holding LLC is the direct owner of 100% of the voting shares of Babson Capital. MassMutual owns all of the voting shares of MassMutual Holding LLC. MassMutual and MassMutual Holding LLC are located at 1295 State Street, Springfield, Massachusetts 01111. Babson Capital has an office at 1500 Main Street, Springfield, Massachusetts 01115 and its principal office is located at Independence Wharf, 470 Atlantic Avenue, Boston, Massachusetts 02210. 24 CERTAIN ADMINISTRATIVE SERVICES MassMutual indirectly provides certain administrative services to each Trust including, but not limited to, accounting services, meeting facilities, legal support, report preparation, and other services provided to Babson Capital, each Trust's investment adviser. MassMutual's principal business address is 1295 State Street, Springfield, Massachusetts 01111. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Each Trust's Trustees and certain officers, investment advisers, certain affiliated persons of the investment advisers, and persons who own more than 10% of any class of outstanding securities of each Trust are required to file forms reporting their affiliation with each Trust and reports of ownership and changes in ownership of each Trust's securities with the SEC and the New York Stock Exchange. These persons and entities are required by SEC regulation to furnish each Trust with copies of all such forms they file. Based solely on a review of these forms furnished to the Trusts as well as certain internal documents, each Trust believes that its Trustees and relevant officers, Babson Capital, and its relevant affiliated persons have all complied with applicable filing requirements during each Trust's fiscal year ended December 31, 2010 with the exception of Donald E. Benson who inadvertently filed a late Form 4 for MPV due to late receipt of trade confirmations in the quarterly Dividend Reinvestment and Cash Purchase Plan.
