    common stock, par value $0.001 per share (the “Common Stock”),
    and one warrant, which is exercisable for one share of Common Stock (the “Warrants”).
    Certain capitalized terms used herein are defined in paragraph 5 hereof.

    will cause each other business entity within the GSC Group to first offer
    (subject to any fiduciary obligations members of management or members of
    the board of directors of such other entities may have), any such business
    opportunity to the Company and the undersigned will not, and will cause each
    other  business entity within the GSC Group and each fund and other investment
    vehicle managed by GSC Group not to, pursue such business opportunity unless
    and until the Company’s board of directors has determined for any reason
    that the Company will not pursue such opportunity. Notwithstanding the foregoing,
    the Right of First Review shall not include, and neither the undersigned
    nor any other business entity within GSC Group shall be required to first
    offer to the Company: 

	 any investment opportunities in respect of companies
      in bankruptcy, or financially or operationally
      distressed companies; and

 

	 companies targeted for acquisition by any company
      in which an investment vehicle managed

    Subject to the review and approval of the Company’s Audit Committee,
    the undersigned and the other entities within GSC Group shall be entitled

    incurred in connection with the IPO and identifying, investigating and consummating
    an Initial Business Combination. In addition, GSCP (NJ) Holdings, L.P. is
    entitled to receive a payment of an aggregate of $7,500 per month for

    other than compensation or fees that may be received for any services provided
    following such Initial Business Combination. 

      3. The
    undersigned agrees that it will not, and will cause each other business entity
    that is part of GSC Group not to, become affiliated with any other blank
    check company until the earlier of (i) the Initial Business Combination and
    (ii) the Company’s liquidation. 

      4. The
    undersigned has full right and power, without violating any agreement by
    which it is bound, to enter into this letter agreement.

    with the laws of the State of New York applicable to contracts formed and

                               REGISTRATION RIGHTS

          SECTION 2.1 Demand Registration.

          (a) If, at any time following the earlier of 180 days after the
effective date of the registration statement for the First Public Offering and
the expiration of the period during which the managing underwriters for the
First Public Offering shall prohibit the Company from effecting any other public
sale or distribution of Company Securities, the Company shall receive a request
from a Major Investor (the "Requesting Shareholder") that the Company effect the
registration under the Securities Act of all or any portion of such Requesting
Shareholder's Registrable Securities, and specifying the intended method of
disposition thereof, then the Company shall promptly give notice of such
requested registration (each, a "Demand Registration") at least 15 Business Days
prior to the effective date of the registration statement relating to such
Demand Registration to the other Shareholders holding Registrable Securities and
thereupon shall use its commercially reasonable efforts to effect, as
expeditiously as possible, subject to Section 2.1(e), the registration under the
Securities Act of:

          (i) all Registrable Securities for which the Requesting Shareholder
     has requested registration under this Section 2.1, and

          (ii) all other Registrable Securities that any other Shareholder has
     requested the Company to register by written request received by the
     Company within ten (10) Business Days after such Shareholder receives the
     Company's notice of the Demand Registration, all to the extent necessary to
     permit the disposition (in accordance with the intended methods thereof as
     aforesaid) of the Registrable Securities so to be registered;

provided that, other than any Demand Registration to be effected pursuant to a
Registration Statement on Form F-3 or S-3, as applicable (or any successor
thereto), for which an unlimited number of Demand Registrations shall be
permitted, and subject to Section 2.1(d), the Company shall not be obligated to
effect more than (i) four (4) Demand Registrations in the aggregate, in the case
of the Qualified Sponsors, and (ii) two (2) Demand Registrations in the
aggregate, in the case of all other Major Investors; provided, further, that the
Company shall not be obligated to effect a Demand Registration unless the
aggregate proceeds expected to be received from the sale of the Registrable
Securities requested to be included in such Demand Registration equals or
exceeds $35,000,000. For the avoidance of doubt, a Participating Shareholder
shall not be deemed to have made a Demand Registration request solely as a
result of participating in a registration statement effected pursuant to a
Demand Registration of another Requesting Shareholder.

          Notwithstanding anything contained herein to the contrary, the Company
shall, at the request of any Major Investor seeking to effect a distribution to,
and resale by, the members or partners of such Major Investor (a "Partner
Distribution"), file at such Major Shareholder's cost and expense any prospectus
supplement or post-effective amendments and otherwise take any action reasonably
necessary to include therein all disclosure and language reasonably deemed
necessary or advisable by such Shareholder if such disclosure or language was
not included in the initial registration statement, or revise such disclosure or
language if reasonably deemed necessary or advisable by such Major Investor, to
disclose

                                      -6-

<PAGE>

the Partner Distribution; provided that the Company shall not be required to
take such action more than once a year with respect to any Shareholder.

          In no event shall the Company be required to effect more than one
Demand Registration hereunder within any six month period.

          (b) Promptly after the expiration of the 10 Business Day period
referred to in Section 2.1(a)(ii), the Company will notify all Participating
Shareholders of the identities of the other Participating Shareholders and the
number of shares of Registrable Securities requested to be included therein. At
any time prior to the effective date of the registration statement relating to
such registration, the Requesting Shareholder may revoke such request, without
liability to any of the other Participating Shareholders, by providing a notice
to the Company revoking such request. Subject to Section 2.1(d), a request, so
revoked, shall be considered to be a Demand Registration unless (i) such
revocation arose out of the fault of the Company (in which case the Company
shall be obligated to pay all Registration Expenses in connection with such
revoked request), (ii) after the date of the Demand Registration request, the
Company postponed effecting the registration pursuant to clause (f) below and
the Requesting Shareholder thereafter revoked such request (in which case the
Company shall be obligated to pay all Registration Expenses in connection with
such revoked request), or (iii) the Requesting Shareholder reimburses the
Company for all Registration Expenses of such revoked request. The Company
agrees to use commercially reasonable efforts to notify the Participating
Shareholders if the price for any Company Securities to be registered for sale
for the account of the Company is expected to occur outside of any expected
pricing range disclosed to the Participating Shareholders; provided that the
Company shall not have any such obligation with respect to any registration
involving the registration of Company Securities only for the account of parties
other than the Company.

          (c) The Company shall be liable for and pay all Registration Expenses
in connection with any Demand Registration, regardless of whether such
Registration is effected, except as set forth in Section 2.1(b)(iii).

          (d) A Demand Registration shall not be deemed to have occurred:

          (i) unless the registration statement relating thereto has become
     effective under the Securities Act and has remained effective for a period
     of at least 180 days (or such shorter period in which all Registrable
     Securities of the Participating Shareholders included in such registration
     have actually been sold thereunder); provided that such registration
     statement shall not be considered a Demand Registration if, after such
     registration statement becomes effective, (i) such registration statement
     is interfered with by any stop order, injunction or other order or
     requirement of the SEC or other governmental agency or court and (ii) less
     than 75% of the Registrable Securities of the Requesting Shareholder sought
     to be included in such registration statement have been sold thereunder; or

          (ii) if the Maximum Offering Size is reduced in accordance with
     Section 2.1(e) such that less than 75% of the Registrable Securities of the
     Requesting Shareholder sought to be included in such registration are
     included.

          (e) If a Demand Registration involves an underwritten Public Offering
and the managing underwriter advises the Company and the Requesting Shareholder
that, in its view, the number of shares of Registrable Securities requested to
be included in such registration (including any securities that the Company
proposes to be included that are not Registrable Securities) exceeds the largest
number of shares that can be sold without having an adverse effect on such
offering, including the price at which

                                      -7-

<PAGE>

such shares can be sold (the "Maximum Offering Size"), the Company shall include
in such registration, in the priority listed below, up to the Maximum Offering
Size:

          (i) first, all Registrable Securities requested to be registered by
     the Participating Shareholders (allocated, if necessary for the offering
     not to exceed the Maximum Offering Size, pro rata among such entities on
     the basis of the relative number of Registrable Securities owned by the
     Participating Shareholders), provided that no Shareholder who is an
     employee of the Company or its subsidiaries shall be entitled to sell
     pursuant to this Section 2.1 any Common Stock received pursuant to an
     employment agreement or a long term incentive plan approved by the Board
     until 180 days following the First Public Offering, and

          (ii) second, any securities proposed to be registered by the Company
     or any securities proposed to be registered for the account of any other
     Persons (including the Company), with such priorities among them as the
     Company shall determine.

          (f) Upon notice to the Requesting Shareholder, the Company may
postpone effecting a registration pursuant to this Section 2.1 on one occasion
during any period of six consecutive months for a reasonable time specified in
the notice but not exceeding 90 days (which period may not be extended or
renewed), if (i) Merrill Lynch, Pierce, Fenner & Smith Incorporated or another
investment banking firm of recognized national standing shall advise the Company
and the Requesting Shareholder in writing that effecting the registration would
materially and adversely affect an offering of securities of the Company the
preparation of which had then been commenced or (ii) the Company is in
possession of material non-public information the disclosure of which during the
period specified in such notice the Company reasonably believes would not be in
the best interests of the Company.

          SECTION 2.2 Piggyback Registration.

          (a) Except in connection with any Demand Registration pursuant to
Section 2.1 hereof, if the Company proposes, at any time after the First Public
Offering, to register any Common Stock under the Securities Act (other than a
registration on Form F-8 or F-4, or S-8 or S-4, as applicable, or any successor
forms, relating to Shares issuable upon exercise of employee stock options or in
connection with any employee benefit or similar plan of the Company or in
connection with a direct or indirect acquisition by the Company of another
Person), whether or not for sale for its own account, the Company shall each
such time give prompt notice at least 15 Business Days prior to the effective
date of the registration statement relating to such registration to each
Shareholder, which notice shall set forth such Shareholder's rights under this
Section 2.2 and shall offer such Shareholder the opportunity to include in such
registration statement the number of shares of Common Stock as each such
Shareholder may request (a "Piggyback Registration"), subject to the provisions
of Section 2.2(b) (it being understood that the rights of each Shareholder set
forth in this Section 2.2 shall also be applicable to the First Public Offering
if the shares of any Shareholder are included in the First Public Offering).
Upon the request of any such Shareholder made within 10 Business Days after the
receipt of notice from the Company (which request shall specify the number of
shares of Common Stock intended to be registered by such Shareholder), the
Company shall use all reasonable efforts to effect the registration under the
Securities Act of all Common Stock that the Company has been so requested to
register by all such Shareholders, to the extent requisite to permit the
disposition of the shares of Common Stock so to be registered; provided that (i)
if such registration involves an underwritten Public Offering, all such
Shareholders requesting to be included in the Company's registration must sell
their Common Stock to the underwriters selected as provided in Section 2.4(f) on
the same terms and conditions as apply to the Company or the Shareholder
requesting such registration, as applicable, and (ii) if, at any time after
giving notice of its intention to register any Common Stock pursuant to this
Section 2.2(a) and prior to the effective date of the registration statement
filed

                                      -8-

<PAGE>

in connection with such registration, the Company shall determine for any reason
not to register such Common Stock, the Company shall give notice to all such
Shareholders and, thereupon, shall be relieved of its obligation to register any
Common Stock in connection with such registration. The Company shall notify the
Participating Shareholders if the price for Common Stock to be registered for
sale for the account of the Company is expected by the Company to occur outside
of any previously publicly announced range; provided that the Company shall not
have any such obligation with respect to any registration involving the
registration of Common Stock only for the account of parties other than the
Company. No registration effected under this Section 2.2 shall relieve the
Company of its obligations to effect a Demand Registration to the extent
required by Section 2.1. The Company shall pay all Registration Expenses in
connection with each Piggyback Registration. For the avoidance of doubt,
participation in a Piggyback Registration shall not in and of itself be deemed
to be an exercise of a Shareholder's Demand Registration rights.

          (b) In any Piggyback Registration (other than any Demand Registration,
in which case the provisions with respect to priority of inclusion in such
offering set forth in Section 2.1(e) shall apply), if the Company determines, or
if Merrill Lynch, Pierce, Fenner & Smith Incorporated or another investment
banking firm of recognized national standing shall advise the Company, that the
number of shares of Common Stock that the Company and such Shareholders intend
to include in such registration exceeds the Maximum Offering Size, the Company
shall include in such registration, in the following priority, up to the Maximum
Offering Size:

          (i) first, so much of the Common Stock proposed to be registered for
     the account of the Company as would not cause the offering to exceed the
     Maximum Offering Size,

          (ii) second, all Common Stock requested to be included in such
     registration by any Shareholders pursuant to this Section 2.2 (allocated,
     if necessary for the offering not to exceed the Maximum Offering Size, pro
     rata among such Shareholders on the basis of the relative number of shares
     of Common Stock owned by such Shareholders), provided that no Shareholder
     who is an employee of the Company or its subsidiaries shall be entitled to
     sell pursuant to this Section 2.2 any Common Stock received pursuant to an
     employment agreement or a long term incentive plan approved by the Board
     until 180 days following the First Public Offering, and

          (iii) third, any securities proposed to be registered for the account
     of any other Persons with such priorities among them as the Company shall
     determine.

          SECTION 2.3 Lock-Up Agreements.

          In connection with any Public Offering, neither the Company nor any
Shareholder shall effect any public sale or distribution of any Company
Securities or other security of the Company (except as part of such Public
Offering) during the period beginning 14 days prior to the effective date of the
applicable registration statement until the earlier of (i) such time as the
Company and the lead managing underwriter shall agree and (ii) 180 days in the
case of the First Public Offering and 90 days in the case of any subsequent
Public Offering.

          SECTION 2.4 Registration Procedures.

          Whenever Shareholders request that any Registrable Securities be
registered pursuant to Sections 2.1 or 2.2, subject to the provisions of such
Sections, the Company shall use all reasonable efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof as quickly as practicable, and, in
connection with any such request:

                                      -9-

<PAGE>

          (a) The Company shall as expeditiously as possible prepare and file
     with the SEC a registration statement on any form for which the Company
     then qualifies or that counsel for the Company shall deem appropriate and
     which form shall be available for the sale of the Registrable Securities to
     be registered thereunder in accordance with the intended method of
     distribution thereof (including Partner Distributions) (and if at such time
     the Company is a "well known seasoned issuer" (within the meaning of the
     Securities Act), the Company shall file an automatic shelf registration
     (unless one is already filed and effective) for Shareholders to use for the
     sale of their Registrable Securities) and use all reasonable efforts to
     cause such filed registration statement to become and remain effective for
     a period of not less than 180 days, or in the case of a shelf registration
     statement, two years (or such shorter period in which all of the
     Registrable Securities of the Participating Shareholders included in such
     registration statement shall have actually been sold thereunder).

          (b) Prior to filing a registration statement or prospectus or any
     amendment or supplement thereto, the Company shall, if requested, furnish
     to each Participating Shareholder and each underwriter, if any, of the
     Registrable Securities covered by such registration statement copies of
     such registration statement as proposed to be filed for their reasonable
     and timely review and comment, and thereafter the Company shall furnish to
     such Shareholder and underwriter, if any, such number of copies of such
     registration statement, each amendment and supplement thereto (in each case
     including all exhibits thereto and documents incorporated by reference
     therein), the prospectus included in such registration statement (including
     each preliminary prospectus and any summary prospectus) and any other
     prospectus filed under Rule 424 or Rule 430A under the Securities Act and
     such other documents as such Shareholder or underwriter may reasonably
     request in order to facilitate the disposition of the Registrable
     Securities owned by such Shareholder. Each Participating Shareholder shall
     have the right to request that the Company modify any information contained
     in such registration statement, amendment and supplement thereto pertaining
     to such Shareholder and the Company shall use all reasonable efforts to
     comply with such request; provided, however, that the Company shall not
     have any obligation so to modify any information if the Company reasonably
     expects that so doing would cause the prospectus to contain an untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein not
     misleading.

          (c) After the filing of the registration statement, the Company shall
     (i) cause the related prospectus to be amended or supplemented by any
     required prospectus amendment or supplement, and, as so amended or
     supplemented, to be filed pursuant to Rule 424 under the Securities Act,
     (ii) comply with the provisions of the Securities Act with respect to the
     disposition of all Registrable Securities covered by such registration
     statement during the applicable period in accordance with the intended
     methods of disposition by the Participating Shareholders set forth in such
     registration statement or amendment or supplement to such prospectus and
     (iii) promptly notify each Participating Shareholder holding Registrable
     Securities covered by such registration statement of any stop order issued
     or threatened by the SEC or any state securities commission and use
     commercially reasonable best efforts to prevent the entry of such stop
     order or to remove it if entered.

          (d) The Company shall use all reasonable efforts to (i) register or
     qualify the Registrable Securities covered by such registration statement
     under such other securities or "blue sky" laws of such jurisdictions in the
     United States as any Participating Shareholder holding such Registrable
     Securities reasonably (in light of such Shareholder's intended plan of
     distribution) requests and (ii) cause such Registrable Securities to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary by virtue of the business and operations

                                      -10-

<PAGE>

     of the Company and do any and all other acts and things that may be
     reasonably necessary or advisable to enable such Shareholder to consummate
     the disposition of the Registrable Securities owned by such Shareholder;
     provided that the Company shall not be required to (1) qualify generally to
     do business in any jurisdiction where it would not otherwise be required to
     qualify but for this Section 2.4(d), (2) subject itself to taxation in any
     such jurisdiction or (3) consent to general service of process in any such
     jurisdiction.

          (e) The Company shall, subject to Section 2.13, immediately notify
     each Participating Shareholder holding such Registrable Securities covered
     by such registration statement, at any time when a prospectus relating
     thereto is required to be delivered under the Securities Act, of the
     occurrence of an event requiring the preparation of a supplement or
     amendment to such prospectus so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus will not contain
     an untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading and promptly prepare and make available to each such
     Shareholder and file with the SEC any such supplement or amendment.

          (f) The Company shall have the right to select the underwriter or
     underwriters in connection with any underwritten Public Offering resulting
     from the exercise by any Major Investor of a Demand Registration or in
     connection with any other underwritten Public Offering, provided that the
     lead underwriter shall, in the case of an underwritten Public Offering
     effected pursuant to Section 2.1, be reasonably acceptable to the
     Shareholders holding a majority of the Registrable Securities proposed to
     be sold in such underwritten Public Offering; and provided, further, that
     in connection with the First Public Offering and any Public Offering
     effected pursuant to Section 2.1, each of GSCP V and Merrill shall be
     entitled to require that the Company appoint Goldman, Sachs & Co. and
     Merrill Lynch, Pierce, Fenner & Smith Incorporated, respectively, to act as
     a lead managing underwriter for the First Public Offering and any such
     Public Offering, provided that, with respect to each such underwriter
     individually (a) each such underwriter shall be at such time recognized as
     a leading underwriter for such securities and (b) GSCP V and Merrill, as
     applicable, shall be Qualified Sponsors at such time, provided the terms
     offered are market terms. In connection with any Public Offering, the
     Company shall enter into customary agreements (including an underwriting
     agreement in customary form) and take such all other actions as are
     reasonably required in order to expedite or facilitate the disposition of
     such Registrable Securities in any such Public Offering, including the
     engagement of a "qualified independent underwriter" in connection with the
     qualification of the underwriting arrangements with the NASD. In connection
     with any Public Offering for which Goldman, Sachs & Co. and/or Merrill
     Lynch, Pierce, Fenner & Smith Incorporated acts as an underwriter, the
     Public Offering shall be effected in such a manner that at no time shall
     Goldman, Sachs & Co. and/or Merrill Lynch, Pierce, Fenner & Smith
     Incorporated hold any shares of Voting Common Stock of the Company.

          (g) Upon execution of confidentiality agreements in form and substance
     reasonably satisfactory to the Company, the Company shall make available
     for inspection by any Participating Shareholder and any underwriter
     participating in any disposition pursuant to a registration statement being
     filed by the Company pursuant to this Section 2.4 and any attorney,
     accountant or other professional retained by any such Shareholder or
     underwriter (collectively, the "Inspectors"), all financial and other
     records, pertinent corporate documents and properties of the Company
     (collectively, the "Records") as shall be reasonably necessary or desirable
     to enable them to exercise their due diligence responsibility, and cause
     the Company's officers, directors and employees to supply all information
     reasonably requested by any Inspectors in connection with such registration
     statement. Records that the Company determines, in good faith, to be
     confidential

                                      -11-

<PAGE>

     and that it notifies the Inspectors are confidential shall not be disclosed
     by the Inspectors unless (i) the disclosure of such Records is necessary to
     avoid or correct a misstatement or omission in such registration statement
     or (ii) the release of such Records is required pursuant to applicable law
     or regulation or judicial process. Each Participating Shareholder agrees
     that information obtained by it as a result of such inspections shall be
     deemed confidential and shall not be used by it or its Affiliates as the
     basis for any market transactions in the Company Securities unless and
     until such information is made generally available to the public. Each
     Participating Shareholder further agrees that, upon learning that
     disclosure of such Records is sought in a court of competent jurisdiction,
     it shall give notice to the Company and allow the Company, at its expense,
     to undertake appropriate action to prevent disclosure of the Records deemed
     confidential. The provisions of this Section 2.4(g) shall not be
     interpreted as requiring any Participating Shareholder to conduct due
     diligence or imparting any due diligence responsibility, unless and only to
     the extent imposed by applicable law.

          (h) The Company shall (i) furnish to each Participating Shareholder
     and to each such underwriter, if any, a signed counterpart, addressed to
     such Shareholder or underwriter, of an opinion or opinions of counsel to
     the Company and (ii) in the case of an underwritten offering, furnish to
     each underwriter and use commercially reasonable efforts to furnish to each
     Participating Shareholder a comfort letter or comfort letters from the
     Company's independent public accountants addressed to such underwriter or
     Shareholder, each in customary form and covering such matters of the kind
     customarily covered by opinions or comfort letters, as the case may be, as
     Shareholders holding a majority of the Registrable Securities being sold in
     the offering or the managing underwriter therefore reasonably requests.

          (i) The Company shall otherwise use all reasonable efforts to comply
     with all applicable rules and regulations of the SEC, and make available to
     its security holders, as soon as reasonably practicable, an earnings
     statement or such other document that shall satisfy the provisions of
     Section 11(a) of the Securities Act and Rule 158 thereunder.

          (j) The Company may require each such Participating Shareholder
     promptly to furnish in writing to the Company such information regarding
     the distribution of the Registrable Securities as the Company may from time
     to time reasonably request and such other information as may be legally
     required in connection with such registration.

          (k) Each such Participating Shareholder agrees that, upon receipt of
     any notice from the Company of the happening of any event of the kind
     described in Section 2.4(e) or 2.13, such Shareholder shall forthwith
     discontinue disposition of Registrable Securities pursuant to the
     registration statement covering such Registrable Securities until such
     Shareholder's receipt of the copies of the supplemented or amended
     prospectus contemplated by Section 2.4(e), and, if so directed by the
     Company, such Shareholder shall deliver to the Company all copies, other
     than any permanent file copies then in such Shareholder's possession, of
     the most recent prospectus covering such Registrable Securities at the time
     of receipt of such notice. If the Company shall give such notice, the
     Company shall extend the period during which such registration statement
     shall be maintained effective (including the period referred to in Section
     2.4(a) or 2.13, as applicable) by the number of days during the period from
     and including the date of the giving of notice pursuant to Section 2.4(e)
     or 2.13, as applicable, to the date when the Company shall make available
     to such Shareholder a prospectus supplemented or amended to conform with
     the requirements of Section 2.4(e).

                                      -12-

<PAGE>

          (l) The Company shall use commercially reasonable best efforts to list
     all Registrable Securities covered by such registration statement on any
     securities exchange or quotation system on which any of the Registrable
     Securities are then listed or traded.

          (m) The Company shall have appropriate officers of the Company (i)
     prepare and make presentations at any "road shows" and before analysts and
     rating agencies, as the case may be, (ii) take other actions to obtain
     ratings for any Registrable Securities and (iii) otherwise use their
     reasonable efforts to cooperate as reasonably requested by the underwriters
     in the offering, marketing or selling of the Registrable Securities,
     including, without limitation, by executing customary underwriting
     agreements.

          (n) The Company shall appoint a transfer agent and registrar for all
     such Registrable Securities covered by such registration statement not
     later than the effective date of such registration statement.

          (o) The Company shall endeavor to deliver to each Participating
     Shareholder and each underwriter, if any, copies of all correspondence
     between the SEC and the Company when all such comments have been
     substantially completed, except to the extent that such correspondence
     contains, in the judgment of the Company, confidential or sensitive
     information.

          (p) The Company shall provide a CUSIP number for all Registrable
     Securities, not later than the effective date of the registration
     statement.

          (q) The Company shall reasonably cooperate with the Participating
     Shareholders and the lead underwriter, if any, to facilitate the timely
     preparation and delivery of certificates not bearing any restrictive
     legends representing the Registrable Securities to be sold, and cause such
     Registrable Securities to be issued in such denominations and registered in
     such names in accordance with the underwriting agreement or, if not an
     underwritten offering, in accordance with the reasonable instructions of
     the Participating Shareholders at least one Business Day prior to any sale
     of Registrable Securities and instruct any transfer agent and registrar of
     Registrable Securities to release any stop transfer orders in respect
     thereof.

          If any registration statement or comparable statement under state
"blue sky" laws refers to any Shareholder by name or otherwise as the
Shareholder of any securities of the Company, then such Shareholder shall have
the right to require, subject to applicable law and requirements imposed,
required or requested by any governmental authority, (i) the insertion therein
of language to the effect that the holding by Shareholders of such securities is
not to be construed as a recommendation by any Shareholders of the investment
quality of the Company's securities covered thereby and that such holding does
not imply that any Shareholder will assist in meeting any future financial
requirements of the Company, or (ii) the deletion of the reference to such
Shareholder.

          SECTION 2.5 Indemnification by the Company.

          The Company agrees to indemnify and hold harmless each Participating
Shareholder holding Registrable Securities covered by a registration statement,
its affiliates, and its and their respective officers, directors, employees,
members, managers, shareholders, partners, representatives, advisors and agents,
and each Person, if any, who controls such Shareholder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages, liabilities and expenses (including
reasonable expenses of investigation and reasonable attorneys' fees and
expenses) ("Damages") caused by or relating to any untrue statement or alleged
untrue statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities

                                      -13-

<PAGE>

(as amended or supplemented if the Company shall have furnished any amendments
or supplements thereto) or any preliminary prospectus, or caused by or relating
to any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading or
any violation by the Company of any rule or regulation promulgated under the
Securities Act or any state securities laws applicable to the Company, except
insofar as such Damages are caused by or related to any such untrue statement or
omission or alleged untrue statement or omission so made based upon information
furnished in writing to the Company by such Shareholder or on such Shareholder's
behalf expressly for use therein.

          The Company also agrees to indemnify any underwriters of the
Registrable Securities, their officers and directors and each Person who
controls such underwriters within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act on substantially the same basis as that of
the indemnification of the Shareholders provided in this Section 2.5 or
otherwise on commercially reasonable terms negotiated on an arm's length basis
with such underwriters.

          SECTION 2.6 Indemnification by Participating Shareholders.

          Each Participating Shareholder holding Registrable Securities included
in a registration statement agrees, severally but not jointly, to indemnify and
hold harmless the Company, its officers, directors and agents and each Person,
if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such Shareholder, but only with respect
to information furnished in writing by such Shareholder or on such Shareholder's
behalf expressly for use in any registration statement or prospectus relating to
the Registrable Securities, or any amendment or supplement thereto, or any
preliminary prospectus. Each such Shareholder also agrees to indemnify and hold
harmless underwriters of the Registrable Securities, their officers and
directors and each Person who controls such underwriters within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act on
substantially the same basis as that of the indemnification of the Company
provided in this Section 2.6. As a condition to including Registrable Securities
in any registration statement filed in accordance with Article 2, the Company
may require that it shall have received an undertaking reasonably satisfactory
to it from any underwriter to indemnify and hold it harmless to the extent
customarily provided by underwriters with respect to similar securities. No
Participating Shareholder shall be liable under this Section 2.6 for any Damages
in excess of the net proceeds realized by such Shareholder in the sale of
Registrable Securities of such Shareholder to which such Damages relate.

          SECTION 2.7 Conduct of Indemnification Proceedings.

          If any proceeding (including any governmental investigation) shall be
instituted involving any Person in respect of which indemnity may be sought
pursuant to this Article 2, such Person (an "Indemnified Party") shall promptly
notify the Person against whom such indemnity may be sought (the "Indemnifying
Party") in writing and the Indemnifying Party shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Party, and shall assume the payment of all fees and expenses; provided that the
failure of any Indemnified Party so to notify the Indemnifying Party shall not
relieve the Indemnifying Party of its obligations hereunder except to the extent
and only to the extent that the Indemnifying Party is materially prejudiced by
such failure to notify. In any such proceeding, any Indemnified Party shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless (i) the Indemnifying
Party and the Indemnified Party shall have mutually agreed to the retention of
such counsel or (ii) in the reasonable judgment of such Indemnified Party
representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them.

                                      -14-

<PAGE>

          It is understood that, in connection with any proceeding or related
proceedings in the same jurisdiction, the Indemnifying Party shall not be liable
for the reasonable fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) at any time for all such Indemnified Parties,
and that all such fees and expenses shall be reimbursed as they are incurred. In
the case of any such separate firm for the Indemnified Parties, such firm shall
be designated in writing by the Indemnified Parties. The Indemnifying Party
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent, or if there be a final
judgment for the plaintiff, the Indemnifying Party shall indemnify and hold
harmless such Indemnified Parties from and against any loss or liability (to the
extent stated above) by reason of such settlement or judgment. Without the prior
written consent of the Indemnified Party, no Indemnifying Party shall effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability arising out
of such proceeding.

          SECTION 2.8 Contribution.

          If the indemnification provided for in this Article 2 is unavailable
to the Indemnified Parties in respect of any Damages, then each such
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Damages (i) as between the Company and the Participating Shareholders
holding Registrable Securities covered by a registration statement on the one
hand and the underwriters on the other, in such proportion as is appropriate to
reflect the relative benefits received by the Company and such Shareholders on
the one hand and the underwriters on the other, from the offering of the
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company and such Shareholders on the
one hand and of such underwriters on the other in connection with the statements
or omissions that resulted in such Damages, as well as any other relevant
equitable considerations and (ii) as between the Company on the one hand and
each such Shareholder on the other, in such proportion as is appropriate to
reflect the relative fault of the Company and of each such Shareholder in
connection with such statements or omissions, as well as any other relevant
equitable considerations. The relative benefits received by the Company and such
Shareholders on the one hand and such underwriters on the other shall be deemed
to be in the same proportion as the total proceeds from the offering (net of
underwriting discounts and commissions but before deducting expenses) received
by the Company and such Shareholders bear to the total underwriting discounts
and commissions received by such underwriters, in each case as set forth in the
table on the cover page of the prospectus. The relative fault of the Company and
such Shareholders on the one hand and of such underwriters on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company and such
Shareholders or by such underwriters. The relative fault of the Company on the
one hand and of each such Shareholder on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by such party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          The Company and the Participating Shareholders agree that it would not
be just and equitable if contribution pursuant to this Section 2.8 were
determined by pro rata allocation (even if the underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
Damages referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or

                                      -15-

<PAGE>

other expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 2.8, no Participating Shareholder shall be required
to contribute any amount for Damages in excess of the net proceeds realized by
such Shareholder in the sale of Registrable Securities of such Shareholder to
which such Damages relate. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. Each Participating Shareholder's obligation to contribute
pursuant to this Section 2.8 is several in the proportion that the net proceeds
of the offering received by such Shareholder bears to the total net proceeds of
the offering received by all such Participating Shareholders and not joint.

          SECTION 2.9 Participation in Public Offering.

          No Person may participate in any Public Offering hereunder unless such
Person (i) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and the provisions of
this Agreement in respect of registration rights.

          SECTION 2.10 Other Indemnification.

          Indemnification similar to that specified herein (with appropriate
modifications) shall be given by the Company and each Participating Shareholder
with respect to any required registration or other qualification of securities
under any federal or state law or regulation or governmental authority other
than the Securities Act.

          SECTION 2.11 Exchange Act Filings, Rule 144.

          If at any time the Company registers any of the Shares pursuant to
Section 12(b) or 12(g) of the Exchange Act, the Company will thereafter (until
such time, if any, as the Shares are deregistered under the Exchange Act) use
commercially reasonable efforts to file reports in compliance with the Exchange
Act and will, at the Company' expense, forthwith upon the reasonable request of
any Shareholder seeking to transfer Shares, deliver to such Shareholder a
certificate, signed by an officer of the Company, containing (to the extent
applicable) the statement contemplated by the third sentence of paragraph (c)(1)
of Rule 144 (unless the Company has already made the statement contemplated by
the second sentence of said paragraph (c)(1)).

          SECTION 2.12 Termination of Registration Rights.

          On and after the fifth anniversary of the date of the Qualified Public
Offering, the rights granted under Section 2.2 shall apply only to Registrable
Securities held by the Shareholders and the provisions of Section 2.3 shall
apply only to Shareholders that hold Registrable Securities.

          SECTION 2.13 Black-Out Period.

          Upon notice to Shareholders with Common Stock registered under a
registration statement effected pursuant to Section 2.1 or 2.2, the Company may
suspend the use of the prospectus included in such registration statement in the
event that and for a period of time (the "Black-Out Period") not to exceed an
aggregate of 90 days during any twelve-month period if the Company is in
possession of material non-public information the disclosure of which during the
period specified in such notice the Company reasonably believes would not be in
the best interest of the Company. Upon receiving such

                                      -16-

<PAGE>

notice, each Shareholder agrees not to use such prospectus until the earlier of
the expiration of such 90 day period or the date such Shareholder receives
notice from the Company that the Black-Out Period has expired.

                                  ARTICLE III.

                        CERTAIN COVENANTS AND AGREEMENTS

          SECTION 3.1 Restrictions.

          Prior to the Qualified Public Offering, the Company shall not, and
shall not permit any of its Subsidiaries to, directly or indirectly, take any of
the following actions without the prior written consent of a Majority of the
Qualified Sponsors:

          (a) issue, repurchase, sell or grant, or enter into any agreement
     providing for the issuance (contingent or otherwise) of, any of its capital
     stock or other equity securities (including, without limitation, any notes
     or debt securities, in each case, containing equity features, and any of
     its Company Securities) except for (A) the issuance of or payment of
     dividends or other distributions payable on the Common Stock solely in the
     form of additional shares of Common Stock, (B) the issuance of shares of
     Common Stock upon the conversion, exchange or exercise of any Company
     Securities outstanding as of the date hereof or issued in a transaction
     that was otherwise subject to this Section 3.1, (C) the issuance of Plan
     Options and/or Common Stock or rights to receive Common Stock under any
     long term incentive plan established by the Board not to exceed 5% of the
     equity of the Company outstanding as of the date of completion of the
     offering contemplated by the Offering Memorandum and the issuance of Common
     Stock upon the conversion, exchange or exercise of Plan Options or rights
     issued under such long term incentive plan, (D) the issuance of Company
     Securities as contemplated by the Offering Memorandum or this Agreement,
     (E) to the extent such transaction is between and among the Company and its
     Subsidiaries and (F) securities issued upon the conversion, exchange and/or
     the exercise of any securities the creation, designation, authorization,
     issuance, sale or grant of which is approved or permitted pursuant to this
     Section 3.1;

          (b) except for letter of credit and similar facilities in support of
     the ordinary course insurance and/or reinsurance operations of the Company
     and its Subsidiaries, create, incur or assume (A) indebtedness (other than
     intercompany indebtedness) for borrowed money or funded indebtedness, (B)
     any lease obligations that would be required to be reflected as a liability
     on the face of the consolidated balance sheet of the Company prepared in
     accordance with U.S. GAAP, (C) any indebtedness described in (A) or (B)
     above guaranteed by the Company or any Subsidiary of the Company (excluding

     $150.0 million in principal amount; or

          (c) engage in any line of business other than the business described

<PAGE>

          SECTION 3.1A Business Activities.

          Unless it has obtained the specific consent of the Board in advance,
the Company will (and will cause its Subsidiaries to) use commercially
reasonable efforts (i) to conduct its operations and the operations of its
non-U.S. Subsidiaries in Bermuda or elsewhere outside the United States and to
limit its activities and the activities of its non-U.S. Subsidiaries such that
neither it nor its non-U.S. Subsidiaries would reasonably be expected to be
considered engaged in a U.S. trade or business for U.S. federal income tax
purposes; (ii) to conduct its business and the business of its Subsidiaries and
to manage its income and assets and those of its Subsidiaries in such a manner
that it and its non-U.S. Subsidiaries would not reasonably be expected to be
considered "passive foreign investment companies" for U.S. federal income tax
purposes; and (iii) to conduct its business and the business of its Subsidiaries
such that no direct or indirect beneficial owner of Company Securities known to
the Company (after reasonable inquiry) would reasonably be expected to have
"related party insurance income" inclusions for U.S. federal income tax purposes
as a result of being such a direct or indirect beneficial owner (assuming that
the relevant Shareholder has provided all relevant information to the Company
upon written request of the Company). For the avoidance of doubt, commercially
reasonable efforts will include, when appropriate, consulting with advisors with
respect to the matters described in this covenant.

          SECTION 3.2 Special Actions.

          Commencing with the eighteen-month anniversary of the date hereof, if
the Qualified Public Offering has not occurred, the Company will take such steps
as are reasonably requested by a Majority of the Qualified Sponsors to
effectuate an initial public offering or, at the Board's option, such other
transaction as will result in Liquidity for all the Common Stock. "Liquidity"
for this purpose shall mean publicly-traded stock or securities or cash.

          SECTION 3.3 Confidentiality.

          (a) Each Shareholder agrees that Confidential Information furnished
and to be furnished to it was and shall be made available in connection with
such Shareholder's investment in the Company. Each Shareholder agrees that it
shall use, and that it shall cause any Person to whom Confidential Information
is disclosed pursuant to clause (i) below to use, the Confidential Information
only in connection with its investment in the Company and not for any other
purpose (including to disadvantage competitively the Company or any other
Shareholder). Each Shareholder further acknowledges and agrees that it shall not
disclose any Confidential Information to any Person, except that Confidential
Information may be disclosed:

          (i) to such Shareholder's Representatives in the normal course of the
     performance of their duties to such shareholder or to any financial
     institution providing credit to such Shareholder,

          (ii) to the extent required by applicable law, rule or regulation
     (including complying with any oral or written questions, interrogatories,
     requests for information or documents, subpoena, civil investigative demand
     or similar process to which a Shareholder is subject); provided that such
     Shareholder give the Company prompt notice of such request(s), to the
     extent practicable, so that the Company may seek an appropriate protective
     order or similar relief (and the Shareholder shall cooperate with such
     efforts by the Company, and shall in any event make only the minimum
     disclosure required by such law, rule or regulation)),

                                      -18-

<PAGE>

          (iii) to any regulatory authority to which the Shareholder or any of
     its affiliates is subject or with which it has regular dealings, as long as
     such authority or agency is advised of the confidential nature of such
     information, or

          (iv) if the prior written consent of the Board shall have been
     obtained.

          (b) "Confidential Information" means any information concerning the
Sponsors or the Company, the Operating Company or any Persons that are or become
its Subsidiaries or the financial condition, business, operations or prospects
of the Company or any such Persons in the possession of or furnished to any
Shareholder; provided that the term "Confidential Information" does not include
information that (i) is or becomes generally available to the public other than
as a result of a disclosure by a Shareholder or its partners, shareholders,
members, directors, officers, employees, agents, counsel, investment advisers or
representatives (all such persons being collectively referred to as
"Representatives") in violation of the applicable agreement, such as the
Subscription Agreement or this Agreement, (ii) is or was available to such
Shareholder on a non-confidential basis prior to its disclosure to such
Shareholder or its Representatives by the Company or the Operating Company,
(iii) was or becomes available to such Shareholder on a non-confidential basis
from a source other than the Company or the Operating Company, which source is
or was (at the time of receipt of the relevant information) not, to the best of
such Shareholder's knowledge, bound by a confidentiality agreement with (or
other confidentiality obligation to) the Company or another Person.

          SECTION 3.4 Conflicting Agreements.

          This Agreement constitutes the entire agreement among the parties
hereto with respect to the subject matter hereof and supersedes all prior
agreements, understandings and arrangements, oral or written, by or among the
parties hereto with respect to the subject matter hereof, other than the
Subscription Agreements, the Bye-laws and the Memorandum.

          SECTION 3.5 Acknowledgment.

          Each Shareholder acknowledges and agrees that none of the Sponsors nor
any of their respective Affiliates is a guarantor of, or is otherwise
responsible for, the Company's profitability or viability.

          SECTION 3.6 Competition; No Fiduciary Duties.

          (a) The Company and each Shareholder acknowledges and agrees that each
Shareholder, its Affiliates and their respective officers, directors, employees
and agents may, alone or in combination with any other person, engage in
activities or businesses, make investments in and acquisitions of any person,
and enter into partnerships and joint ventures with any person, whether or not
competitive now or in the future with the businesses or activities of the
Company, and neither the Company nor any Shareholder shall have the right to
disclosure of any information in regard thereto (except to the extent required
by, or reasonably necessary to ensure each Shareholder's and the Company's
compliance with, applicable law, including the Code or as required by the
Company's Bye-Laws relating to disclosure by directors of conflicts of
interest), to participate therein, or to derive any profits therefrom.
Notwithstanding the foregoing, this Section 3.6 shall not permit any Shareholder
to use Confidential Information in a manner prohibited by Section 3.3 or other
applicable law.

          (b) The Company and each Shareholder acknowledges and agrees that no
Shareholder, nor any of its Affiliates or any of their respective officers,

have any obligation to refer to the Company any business opportunities presented
or developed by any of them.

          (c) The Company and each Shareholder acknowledges and agrees that
certain Shareholders are, and may in the future be, engaged in businesses and
activities which, directly or indirectly, compete with the businesses of the
Company or its Subsidiaries. The Shareholders agree that no violation of this
Agreement shall exist as a result of: (i) the fact that a director, officer or
employee of a Shareholder or any Affiliate thereof that is familiar with the
activities and operations of the Company or its Subsidiaries (as a director,
officer or employee of the Company or the Operating Company or otherwise)
engages in, or participates in a supervisory capacity relating to, a similar or
competing activity (it being understood that such circumstances are expected to
occur); or (ii) the existence of any activity or business of any Shareholder or
Affiliate thereof which is similar to or competes with, directly or indirectly,
the business of the Company or the Operating Company.

          (d) The Company and each Shareholder acknowledges and agrees that no
Shareholder shall have any fiduciary duties to the Company or to any other
Shareholder with respect to the matters covered by this Section 3.6.

          (e) For the avoidance of doubt, the provisions of this Section 3.6
shall not in any way affect or diminish any separate undertaking under any
separate agreement entered into between the Company or its Subsidiaries, on the
one hand, and any other Person, on the other, or any obligation or duty owed as
a result of a Person's capacity as an employee, director, consultant or agent or
any similar capacity of the Company or its Subsidiaries.

          SECTION 3.7 Accounting; Financial Statements and other Information.

          (a) The Company will maintain a system of accounting established and
administered in accordance with U.S. GAAP. During any period when the Company is
not subject to the reporting obligations of Section 15(d) of the Exchange Act,
the Company agrees to provide to each Shareholder as promptly as practicable
following (a) the end of each of the first three fiscal quarters of the year
(commencing with the quarter ending March 31, 2006) an unaudited quarterly
report setting forth its balance sheet as of the end of such period, its
statement of income for such period and its statement of cash flows for such
period, in each case prepared in accordance with U.S. GAAP and (b) the end of
each fiscal year of the Company (commencing with the fiscal year ending December
31, 2006), an audited annual report setting forth its balance sheet as of the
end of such period, its statement of income for such period, statement of
changes in shareholders' equity for such period and its statement of cash flows
for such period, in each case prepared in accordance with U.S. GAAP.

          SECTION 3.8 Insurance.

          The Company shall obtain and maintain directors' and officers'
liability insurance for the benefit of all the directors and officers (and, if
the Board so determines in its sole discretion, any employees of the Company or
the Operating Company), in each case on such terms and conditions as the Board
shall approve in its sole discretion.

          SECTION 3.9 Certain Tax Matters.

          At the end of each fiscal year, the Company will provide to each
Shareholder a statement of whether the Company believes that it is or is not a
"passive foreign investment company" or "PFIC" for U.S. federal income tax
purposes. If the Company believes that it is a PFIC, it will take commercially

                                      -20-

<PAGE>

reasonable efforts to provide Shareholders with the necessary information for
Shareholders to make the "qualified electing fund" election described in Section
1295(b) of the Code.

          SECTION 3.10 Ratification of Board.

          Each Shareholder shall have the right to ratify the directors and
Designated Company Directors (as defined in the Bye-laws) of the Company by
delivering the investor election set forth as Exhibit B hereto.

          SECTION 3.11 Listed Transactions.

          It is the intention of the Company that neither the Company nor any of
its Subsidiaries will enter into any transaction that is, at the time such
transaction is entered into, a "listed transaction" within the meaning of U.S.
Treasury regulations promulgated under Section 6011 of the Code and, if the
Company or any of its Subsidiaries participate in a reportable transaction
described in the aforesaid U.S. Treasury regulations, the Company will provide
to the Shareholders information sufficient for the Shareholders to timely comply
with any resulting U.S. tax reporting obligations.

                                   ARTICLE IV.

court or that any such suit, action or proceeding which is brought in any such
court has been brought in an inconvenient form. Process in any such suit, action
or proceeding may be served on any party anywhere in the world, whether within
or without the jurisdiction of any such court. Without limiting the foregoing,
each party agrees that service of process on such party as provided in Section

entitled to obtain equitable relief in the form of specific performance, a
temporary restraining order, a temporary or permanent injunction or any other
equitable remedy that may then be available.
