           The name, business address, citizenship and title of each executive
officer or director of MPIII, Inc., CSFBPE, CSFB-USA, CSFBC and the CSFB
Entities that are corporations are set forth in Schedules A-1 through A-6
attached hereto, each of which is incorporated by reference.

           Except as otherwise provided herein, during the past five (5) years,
neither any of the Reporting Persons nor, to the best knowledge of any of the
Reporting Persons, any person listed on the schedules hereto has been (i)
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to United States
federal or state securities laws or finding any violation with respect to such
laws.

           On January 22, 2002, CSFBC, without admitting or denying any alleged
violation, entered into coordinated settlements with NASD Regulation, Inc.
("NASDR") and the Securities and Exchange Commission ("SEC") resolving all
outstanding investigations of CSFBC into the allocation of shares in initial
public offerings ("IPOs"). CSFB-USA is the sole stockholder of CSFBC.

           CSFBC consented to these settlements without admitting or denying any
of the allegations made in the SEC's Complaint or the Letter of Acceptance,
Waiver and Consent ("AWC") filed with the NASDR. The SEC and NASDR alleged that,
between April 1999 and June 2000, certain CSFBC employees allocated many shares
in IPOs to over 100 customers with whom they had improper profit-sharing
arrangements. The NASDR and SEC alleged that certain employees allocated "hot"
IPO shares to certain customers who paid the Firm a portion of the profits
(between 33 and 65 percent) that they made when they sold their IPO stock, by
paying inflated brokerage commissions on transactions unrelated to the IPO
shares.

           Under the terms of the coordinated settlement:

                  o        CSFBC paid a total of $100 million. This amount
                           included $30 million in fines and civil penalties
                           divided evenly between the SEC and NASDR, and a total
                           of $70 million in disgorgement, $35 million of which
                           was paid to the U.S. Treasury and $35 million of
                           which was paid to the NASDR, representing the monies
                           obtained as a result of the conduct described by the
                           SEC and NASDR. The SEC determined in this case that
                           it was appropriate and in the public interest to pay
                           funds to the U.S. Treasury rather than to any third
                           parties.

                  o        CSFBC has adopted and is implementing revised
                           policies and procedures for allocating IPOs in its
                           broker-dealer operations. The SEC and NASD have
                           reviewed these policies and procedures. These
                           included the establishment of an IPO Allocation
                           Review Committee, a process for the pre-qualification
                           of accounts before they are eligible to receive IPO
                           allocations, and enhanced supervisory procedures,
                           which may include the review of commissions paid by
                           certain accounts receiving allocations around the
                           time of the IPO. CSFBC also agreed to retain an
                           independent consultant to review the implementation
                           of these policies and procedures one year from the
                           date of the settlement.

           In the NASDR settlement, CSFBC, without admitting or denying any
findings, consented to a censure and findings that it violated NASD Rules 2110,
2330, 2710, 3010 and 3110. These Rules (a) require broker-dealers to adhere to
just and equitable principles of trade, (b) prohibit broker-dealers from sharing
in the profits of client accounts except as specifically provided, (c) require a
managing underwriter to file certain information that may have a bearing on the
NASDR's review of underwriting arrangements, (d) require members to establish,
maintain and enforce a reasonable supervisory system, and (e) require
broker-dealers to maintain certain books and records. The NASDR AWC also found


                                       13

violations of Section 17(a) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and SEC Rule 17a-3, thereunder, which are incorporated by
NASD Rule 3110 and similarly impose certain record keeping requirements on CSFBC
as a broker-dealer. In the SEC settlement, CSFBC, without admitting or denying
the allegations of the Complaint, consented to entry by the District Court for
the District of Columbia of a final judgment that: (1) permanently enjoined
CSFBC, directly or indirectly, from violations of NASD Conduct Rules 2110 and
2330 and Section 17(a)(1) of the Exchange Act and SEC Rule 17a-3; and (2)
ordered CSFBC to comply with certain undertakings.

           Neither the SEC nor NASDR made any allegations or findings of
fraudulent conduct by CSFBC. Further, neither the SEC nor NASDR alleged that any
IPO prospectus was rendered false or misleading by CSFBC's conduct or that this
conduct affected either the offering price of an IPO or the price at which any
IPO stock traded in the aftermarket.

           On November 26, 1996, the SEC brought a civil action in federal court
in California against CS First Boston Corporation ("CS First Boston") and two
former employees of its public finance department relating to CS First Boston's
role as lead underwriter of a September 1994 Orange County pension obligation
bond ("POB") financing, which the county completed 10 weeks prior to its
bankruptcy. The SEC alleged that the Official Statement misrepresented and
omitted material facts about the Orange County Investment Pool, including the
Pool's investment strategy, the risks of that strategy and the Pool's investment
losses, and it sought to hold CS First Boston responsible for the alleged
omissions and misrepresentations. The complaint alleged violations of certain
anti-fraud provisions, including Section 17(a) of the Securities Act, Section
10(b) of the Exchange Act and Rule 10b-5 thereunder, Section 15B(c)(1) of the
Exchange Act, and MSRB Rule G-17. CS First Boston filed its answer to the
complaint on January 13, 1997, in which it denied all allegations of misconduct
and asserted twelve affirmative defenses.

           On January 29, 1998, the lawsuit was dismissed with prejudice, upon
the consent of the SEC, CS First Boston and the individual defendants, as part
of an out-of-court settlement of this matter. Also pursuant to that settlement,
CS First Boston and the individual defendants, without admitting or denying
liability, consented to the entry of a SEC administrative order finding
negligence-based violations of Sections 17(a)(2) and (a)(3) of the Securities
Act and MSRB Rule G-17. CS First Boston and the two individuals agreed to pay
monetary penalties of $800,000, $35,000 and $35,000 respectively. The SEC
administrative order contained no allegation or finding of any fraudulent,
intentional or reckless misconduct by CS First Boston or any of its current or
former employees.

           ----------------------
           (1) Each of the Nautilus Entities have shared voting and dispositive
power with respect to the shares of Common Stock held by Nautilus. However, the
partnership agreements of each of Nautilus, Nautilus Intermediary, and Nautilus
AIV grants, directly or indirectly, the ultimate voting and dispositive power
with respect to the shares of Common Stock held by Nautilus to Nautilus Special
GP. While the CSFB Entities, including Partners III, MBP III LP, MPIII Inc. and
the entities listed below, disclaim beneficial ownership of the securities to
which this statement relates, as a result of the relationship of the CSFB
Entities to, and the pecuniary interest of the CSFB Entities in, Partners III,
Nautilus AIV and CSFBPE, as described in Item 2 above, under the Exchange Act
such entities may be deemed to beneficially own the securities to which this
statement relates. CSG, for purposes of the federal securities laws, may be
deemed ultimately to control the Bank and the other CSFB Entities. CSG, its
executive officers and directors, and its direct and indirect subsidiaries
(including Asset Management and the Credit Suisse Financial Services business
unit) may beneficially own shares of Common Stock and such securities are not
reported in this statement. CSG disclaims beneficial ownership of the securities
to which this statement relates that are beneficially owned by its direct and
indirect subsidiaries, including the Nautilus Entities and the CSFB Entities.
The Nautilus Entities and the CSFB Entities disclaim beneficial ownership of
shares of Common Stock beneficially owned by CSG, Asset Management and the
Credit Suisse Financial Services business unit. Due to their interest in
Nautilus Special GP, Craig, Dean and Huseman may be deemed to beneficially own
the shares of Common Stock and Warrants held by Nautilus. Craig, Dean, and
Huseman disclaim beneficial ownership of such shares of Common Stock and
Warrants held by Nautilus. The Reporting Persons may be considered a group
together with the C/R Entities and therefore be deemed to beneficially own the
shares beneficially owned by the C/R Entities, but no Reporting Person affirms
the existence of any such group. The Reporting Persons disclaim any such
beneficial ownership.

           (2) These numbers represent warrants held by CSFBC. The Nautilus
Entities and the Reporitng Persons disclaim beneficial ownership of such
warrants and the shares of Common Stock issuable upon the exercise of such
warrants owned by CSFBC.

           (3)The following information has been obtained from the C/R Entities:
Each of the C/R Purchasers has shared power to dispose or direct the disposition
of the shares of Common Stock and Warrants which it would hold directly or the
shares of Common Stock issuable upon exercise of such Warrants. Each of the C/R


                                       16

Purchasers has shared power to vote or direct the vote of such shares of Common
Stock, but does not have the power to vote or direct the vote of any of the
shares of Common Stock which it would own upon exercise of such Warrants prior
to the receipt of such shares of Common Stock upon exercise of such Warrants.
The C/R Entities may be deemed to be acting as a group in relation to their
respective holdings in the Company but do not affirm the existence of any such
group. Each of the C/R Entities disclaims beneficial ownership of any shares of
Common Stock owned by any other C/R Entity.

           (4) The following information has been obtained from the C/R
Entities: C/R GP is the sole general partner of each of the C/R Purchasers and
exercises investment discretion and control over the shares of Common Stock held
by each of the C/R Purchasers. Hence, in such capacity, C/R GP may be deemed to
have power to dispose and direct the disposition of the shares of Common Stock
and Warrants that each of the C/R Purchasers would hold, and shares of Common
Stock which each of the C/R Purchasers would hold upon exercise of such
Warrants. William E. Conway, Jr., Daniel A. D'Aniello, David M. Rubenstein,
Pierre F. Lapeyre, Jr., David M. Leuschen and Jim H. Derryberry, as the sole
stockholders of C/R GP, may be deemed to share beneficial ownership of the
shares shown as beneficially owned by the C/R Entities. Such persons disclaim
any such beneficial ownership.

           All calculations made herein are made in accordance with Rule
13d-3(d), promulgated under the Securities Exchange Act of 1934, as amended, and
based on the shares of Common Stock outstanding as of July, 10, 2002, as
reported by the Company in its proxy statement, filed as of August 14, 2002.

           (c) None of the Reporting Persons has effected any transactions in
shares of Common Stock during the past 60 days.

           (d) The right to receive dividends on, and proceeds from the sale of,
the shares of Common Stock held of record by Nautilus and beneficially owned as
described in paragraphs (a) and (b) above is governed by the organizational
documents of each such entity, and such dividends or proceeds may be distributed
with respect to numerous general and limited partnership interests.

           (e) Not applicable.

           RESPECT TO SECURITIES OF THE ISSUER.

                                       17

           Pursuant to the Company Purchase Agreement, the Company paid the
expenses of Nautilus and the C/R Purchasers incurred since January 1, 2002 upon
the Closing.

           Upon the Closing, the Company, Nautilus, the C/R Purchasers and
Gerhard Kurz entered into the Stockholders' Agreement described below.

           Loomis Securities Purchase Agreement

           The following description of the Loomis Securities Purchase Agreement
is a summary thereof and does not purport to be complete and is qualified in its
entirety by reference to the Loomis Securities Purchase Agreement.

           Pursuant to the Loomis Securities Purchase Agreement, Loomis Sayles
sold to Nautilus and the C/R Purchasers, and Nautilus and the C/R Purchasers
purchased from Loomis Sayles, 4,949,946 shares of Common Stock for a price of
$8.00 per share; 44,638 Class A Common Stock Purchase Warrants for a price of
$.01 per warrant, with one Class A Common Stock Purchase Warrant being
exercisable for one share of Common Stock at an exercise price of $38.49; and
123,547 Common Stock Purchase Warrants for a price of $7.99 per warrant, with
one Common Stock Purchase warrant being exercisable for one share of Common
Stock at an exercise price of $0.01 (collectively, the "Warrants").

           The sale and purchase of the Common Stock and the Warrants (the
"Loomis Closing") occurred on September 13, 2002.

           Stockholders' Agreement

           On the Closing Date, the Company, the C/R Purchasers, Nautilus (each,
an "Investor", and collectively, the "Investors") and Gerhard Kurz entered into
the Stockholders' Agreement. Among other things:

           The Stockholders' Agreement provides that certain of the parties will
vote the shares owned by them to cause the Company's board of directors to
consist of ten members and be constituted as follows:

         o        certain of the C/R Purchasers will be entitled to designate
                  two directors;

         o        Nautilus will be entitled to designate four directors;

         o        three directors will be independent directors (that is,
                  non-Investor designated directors), who initially will be
                  chosen from directors currently serving on the board of
                  directors; and

         o        the Chief Executive Officer will serve as a director.

           The Stockholders' Agreement also provides that directors designated
by Nautilus and certain of the C/R Purchasers will also be represented on the
compensation committee and, subject to compliance with Nasdaq and Commission
rules, the audit committee of the board of directors.

           In the event that the C/R Purchasers own less than 50%, but more than
10%, of the shares of Common Stock initially purchased by them pursuant to the
Purchase Agreements, collectively, they will be entitled to designate only one
director. In the event the C/R Purchasers own less than 10% of the shares of
Common Stock initially purchased by them pursuant to the Purchase Agreements,
collectively, they will no longer be entitled to designate a director.

           In the event that Nautilus owns less than 50%, but more than 10%, of
the shares of Common Stock initially purchased by it pursuant to the Purchase
Agreements, it will be entitled to designate only two directors. In the event
Nautilus owns less than 10%, but more than 5%, of the shares of Common Stock
initially purchased by it pursuant to the Purchase Agreements, it will be
entitled to designate only one director. In the event Nautilus owns less than 5%
of the stock initially purchased by it pursuant to the Purchase Agreements, it
will no longer be entitled to designate a director.


                                       18

           So long as either Nautilus or the C/R Purchasers own shares of Common
Stock equaling at least 15% of the outstanding shares of the Common Stock on a
fully diluted basis (each, a "15% Holder"), the unanimous vote of the directors
designated by such 15% Holder will be required for the following actions:

         o        share repurchases by the Company;

         o        certain affiliated party transactions;

         o        equity or debt financings; and

         o        amendments to the Company's certificate of incorporation or
                  by-laws, including any changes to the number of directors.

           The C/R Purchasers and Nautilus have the right to require the Company
to effect up to six demand registrations, provided that shares of Common Stock
to be offered in any such registration have an aggregate offering price in
excess of $20 million. The C/R Purchasers are entitled to request two demand
registrations, and Nautilus is entitled to request four demand registrations.
The Company has customary "black-out" rights to delay a registration. If a
demand registration is to involve an underwritten public offering, the Investor
requesting such registration has the right to select the underwriters.

           The C/R Purchasers and Nautilus have unlimited "piggyback"
registration rights, subject to customary pro rata reductions based on the
number of shares requested to be covered under such registration.

           All fees and expenses (including reasonable fees and expenses of
counsel) in connection with a registration will be paid by the Company, other
than underwriting fees and discounts.

           The parties, other than the Company, to the Stockholders' Agreement
are subject to certain rights of first refusal and tag-along rights in any
proposed transfer of shares of Common Stock owned by them. Specifically, the C/R
Purchasers and Nautilus have pro rata tag-along rights in any proposed transfer
of any shares of Common Stock owned by other Investors. All parties, other than
the Company, also have the right of first refusal to purchase any shares
proposed to be transferred by any party other than the Company on a pro rata
basis (based on the number of shares held by such Investor), except that Kurz
may sell a limited number of shares each year without being subject to the such
right of first refusal. The rights of first refusal and tag-along rights are
subject to limited customary exceptions, including sales pursuant to Rule 144 of
the Securities Act of 1933, as amended, sales pursuant to demand or piggy-back
registration rights and sales to certain permitted transferees.

           No party to the Stockholders' Agreement may transfer shares of Common
Stock owned by it to the extent that such transfer would result in the Company's
not meeting the requirements of Section 2 of the Shipping Act, 1916, as amended,
commonly referred to as the Jones Act, for the ownership and operation of
vessels in the United States coastwise trade. Subject to this transfer
restriction, the rights and obligations of the C/R Purchasers and Nautilus under
the Stockholders' Agreement would be assigned in connection with any transfer of
shares of Common Stock, provided that the right to designate a member of the
board of directors may not be assigned and registration rights are assignable
only if the transferee is acquiring at least 500,000 shares of Common Stock
(assuming exercise of all Warrants).

           Except with respect to registration rights, the Stockholders'
Agreement will terminate upon a change of control of the Company. The
Stockholders' Agreement would not terminate upon a future public offering of
shares of Common Stock.

           With respect to registration rights, such rights will terminate upon
the earlier of (1) the seventh anniversary of the date of the Stockholders'
Agreement or (2) when, with respect to each Investor, such Investor owns less
than 3% of the shares of Common Stock (including upon exercise of all Common
Stock Purchase Warrants) initially purchased by such Investor pursuant to the
Purchase Agreements.

           The following description of the Fee Letter is a summary thereof and

Partners, L.P. in an amount of $1,000,000. Upon the Closing, the Company paid a
