ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Bye-Law 145 of the Registrant's bye-laws provides, among other things, that, subject to certain provisos, the Registrant's directors, officers or any other person appointed to a committee of the board of directors and any resident representative (and their respective heirs, executors or administrators; collectively, the "Indemnified Persons") shall be indemnified and held harmless out of the assets of the Registrant against all liabilities, loss, damage or expense (including but not limited to liabilities under contract, tort and statute or any applicable foreign law or regulation and all reasonable legal and other costs and expenses properly payable) incurred or suffered by him by or by reason of any act done, conceived in or omitted in the conduct of the Registrant's business or in the discharge of his duties and the indemnity contained in Bye-Law 145 shall extend to the Indemnified Persons of the Registrant acting in any office or trust in the reasonable belief that he has been appointed or elected to such office or trust notwithstanding any defect in such appointment or election provided always that the indemnity contained in this Bye-Law 145 shall not extend to any matter which would render it void under the Companies Acts.

Bye-Law 149 of the Registrant's bye-laws provides that each shareholder and the Registrant agree to waive any claim or right of action he or it may at any time have, whether individually or by or in the right of the Registrant, against any director or officer of the Registrant on account of any action taken by such director or officer or the failure of such director or officer to take any action in the performance of his duties with or for the Registrant, provided, however, that such waiver shall not apply to any claims or rights of action arising out of the fraud of such director or officer or to recover any gain, personal profit or advantage to which such director or officer is not legally entitled.

The Companies Act provides that a Bermuda company may indemnify its directors in respect of any loss arising or liability attaching to them as a result of any negligence, default, breach of duty or breach of trust of which they may be guilty. However, the Companies Act also provides that any provision, whether contained in the Company's bye-laws or in a contract or arrangement between the

II-1


Company and the director, indemnifying such director against any liability which would attach to him in respect of his fraud or dishonesty will be void.

The Registrant has purchased directors and officers liability insurance policies. Such insurance will be available to the Registrant's directors and officers in accordance with its terms. In addition, certain directors may be covered by directors and officers liability insurance policies purchased by their respective employers, subject to the limitation of the policy terms.

Reference is made to the form of Underwriting Agreement to be filed as Exhibit 1.1 hereto for provisions providing that the Underwriters are obligated, under certain circumstances, to indemnify the directors, certain officers and the controlling persons of the Registrant against certain liabilities under the Securities Act of 1933, as amended (the "Securities Act").

ITEM 7. RECENT SALES OF UNREGISTERED SECURITIES

Since its formation, the Registrant has issued unregistered securities as described below. None of the transactions involved any underwriters, underwriting discounts or commissions, or any public offering and the Registrant believes that each transaction, if deemed to be a sale of a security, was exempt from the registration requirements of the Securities Act by virtue of Section 4(2) thereof, Regulation D promulgated thereunder, Rule 701 pursuant to compensatory benefit plans and contracts relating to compensation as provided under Rule 701 or Regulation S for offerings of securities outside of the United States. The recipients of securities in each such transaction represented their intention to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, such securities were restricted as to transfers and appropriate legends were affixed to the share certificates and instruments issued in such transactions.

o On June 21, 2002, the Registrant sold 24,859,590 ordinary shares to certain accredited investors and members of management of the Registrant for an aggregate price of $372,893,850 (based on the British Pound/U.S. Dollar exchange rate on such date at (pounds sterling)1 to $1.5000). The sale of ordinary shares was made in reliance on Section 4(2) of the Securities Act.

o On October 16, 2002, the Registrant sold 4,625,070 ordinary shares to Wellington for an aggregate price of $73,052,040 (based on the British Pound/U.S. Dollar exchange rate on such date at (pounds sterling)1 to $1.5543). The sale of ordinary shares was made in reliance on Section 4(2) of the Securities Act.

o On November 19, 2002, the Registrant sold 4,874,930 ordinary shares to Wellington for an aggregate price of $79,044,003 (based on the British Pound/U.S. Dollar exchange rate on such date at (pounds sterling)1 to $1.5884).

o On November 29, 2002, the Registrant sold 2,555,230 ordinary shares to Wellington for an aggregate price of $40,497,797 (based on the British Pound/U.S. Dollar exchange rate on such date at (pounds sterling)1 to $1.5523). The sale of ordinary shares was made in reliance on Section 4(2) of the Securities Act.

o On November 29, 2002, the Registrant sold 19,951,320 ordinary shares to certain accredited investors and members of management of the Registrant for an aggregate price of $299,269,800 (based on the British Pound/U.S. Dollar exchange rate on June 21, 2002 at (pounds sterling)1 to $1.5000 since this subscription was the second part of the June 21, 2002 subscription). The sale of ordinary shares was made in reliance on Section 4(2) of the Securities Act.

II-2

ITEM 9. UNDERTAKINGS

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

2.1 Until the date that is thirty-six (36) months after the Effective Date, if any Shareholder Party wishes to transfer any of its Shares to another person (a "TRANSFEREE"), other than a transfer (i) to the Company, (ii) pursuant to a Public Sale, (iii) the consummation of which will result in a Change of Control or (iv) to a Permitted Distributee in connection with a Permitted Distribution by such Shareholder Party, such Shareholder Party shall, as a condition of such transfer, require the Transferee to execute and deliver a deed of adherence to this Agreement, substantially in the form of Schedule 2 hereto; provided that a Permitted Distributee shall be required to execute and deliver a deed of adherence in such form if (A) (x) such Permitted Distributee is an Affiliate of such Shareholder Party and (y) following such Permitted Distribution such Permitted Distributee holds a number of ordinary shares of the Company which, when taken together with the number of ordinary shares of the Company then held by such Shareholder Party and all other undertakings that are Affiliates of such Shareholder Party, equals or exceeds 5% of the number of issued and authorized ordinary shares of the Company (on a fully-diluted basis, taking into account all vested and exercisable options, warrants or rights to acquire any ordinary shares of the Company and any securities immediately convertible into or exchangeable or exercisable for ordinary shares) or (B) such Permitted Distributee and each other Permitted Distributee in such Permitted Distribution is either an Affiliate or Associated Person of such Shareholder Party. During the period commencing on the Effective Date through the first anniversary of the Effective Date, a Shareholder Party shall not be entitled to transfer any of its Shares by way of a dividend, distribution or comparable transfer to any shareholder, member, partner, limited partner or beneficiary (as the case may be) of such Shareholder Party. A Shareholder Party may transfer its Shares only in accordance with, and subject to all applicable provisions of, this Agreement, the Registration Rights Agreement and the Bye-Laws.

2.2 No Shares may be transferred by any Shareholder Party (other than pursuant to an effective registration statement under the Securities Act) unless such Shareholder Party first delivers to the Company, if requested by the Company, a written opinion of counsel reasonably satisfactory to the Company to the effect that such transfer is not required to be registered under the Securities Act.

9

2.3 Each certificate representing Shares held by a Shareholder Party shall be stamped or otherwise imprinted with a legend in substantially the following form:

"THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN TRANSFER RESTRICTIONS CONTAINED IN THE AMENDED AND RESTATED SHAREHOLDERS' AGREEMENT DATED AS OF SEPTEMBER 30, 2003 AND THE AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT DATED AS OF SEPTEMBER 30, 2003, AS EACH MAY BE AMENDED FROM TIME TO TIME, AND MAY NOT BE TRANSFERRED EXCEPT IN ACCORDANCE THEREWITH. COPIES OF SUCH DOCUMENTS ARE ON FILE AT THE REGISTERED OFFICE OF THE COMPANY. THE HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE HEREOF, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF SUCH DOCUMENTS."

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY UNITED STATES STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF UNLESS
(I)(A) A REGISTRATION STATEMENT IS IN EFFECT UNDER THE SECURITIES ACT WITH RESPECT TO SUCH SHARES, OR (B) AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE SECURITIES ACT IS AVAILABLE OR THE SECURITIES ACT DOES NOT APPLY (AND, IN SUCH CASE, AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY SHALL HAVE BEEN DELIVERED TO THE COMPANY TO SUCH EFFECT), AND (II) IF REQUIRED BY LAW, THE TRANSFEREE IS APPROVED BY APPLICABLE BERMUDA REGULATORY AUTHORITIES."

In the event that any Shares (x) shall cease to be subject to the restrictions described in the first restrictive legend set forth above in this clause 2.3 in accordance with the terms of this Agreement and the Registration Rights Agreement, (y) shall cease (in the written opinion of counsel reasonably satisfactory to the Company) to be subject to the restrictions described in the second restrictive legend set forth above in this clause 2.3 or (z) are to be disposed in connection with an effective registration statement under the Securities Act, then, in each case, the Company shall, upon the written request of the holder thereof and surrender of the legended certificate representing such Shares, promptly issue to such holder a new certificate representing such Shares without the inapplicable restrictive legend or legends.

3. TAG ALONG RIGHTS

3.1 If any Shareholder Party or group of Shareholder Parties (individually or collectively, a "TAG-ALONG SELLER") proposes to transfer to a person and such person's Affiliates (a "TAG-ALONG PURCHASER"), other than (i) a transfer to the Company, (ii) a Public Offering, (iii) a Rule 144 Sale pursuant to a broker's transaction (within the meaning of Section 4(4) of the Securities Act) or a transaction directly with a market maker (as that term is defined in Section 3(a)(38) of the Exchange Act), in either case, in response to an unsolicited offer

10

or (iv) a Permitted Transfer by such Shareholder Party, a number of ordinary shares of the Company ("SUBJECT SHARES") comprising at least 20% of the Subject Shares in issue (on a fully-diluted basis, taking into account all vested and exercisable options, warrants or rights to acquire any Subject Shares and any securities immediately convertible into or exchangeable or exercisable for Subject Shares), in a single transaction or in a series of related transactions (a "TAG-ALONG SALE"), the Tag-Along Seller shall provide each other Shareholder Party that holds Subject Shares (each a "RELEVANT SHAREHOLDER") notice of the terms and conditions of such proposed transfer to the Tag-Along Purchaser ("TAG-ALONG NOTICE") and offer each Relevant Shareholder the opportunity to participate, and each Relevant Shareholder may elect, at its option, to participate in the proposed Tag-Along Sale in accordance with this clause 3 (each such electing Relevant Shareholder, a "TAGGING PERSON"). In the event of any Tag-Along Sale for ordinary shares of the Company, each Wellington Entity that holds vested options under the Wellington Option shall be deemed to be a Relevant Shareholder and shall be entitled to participate in the proposed Tag-Along Sale (and, if such Wellington Entity so elects to participate, shall be deemed a Tagging Person) in respect of the Subject Shares underlying such vested options. In the event that the proposed Tag-Along Sale would result in a Change of Control, then each Management Shareholder shall be deemed to be a Relevant Shareholder and shall be entitled to participate in the proposed Tag-Along Sale (and, if he or she so elects to participate, shall be deemed a Tagging Person) in respect of (x) the Subject Shares owned by such Management Shareholder and (y) the Subject Shares underlying any options, warrants, rights or securities exercisable or exchangeable for, or convertible into, Subject Shares, provided that, if any of such options, warrants, rights or securities are subject to vesting, only upon and to the extent of such vesting and subject to the terms and conditions of Section 3(d) in the shareholder's agreement between such Management Shareholder and the Company (each, a "MANAGEMENT SHAREHOLDER'S AGREEMENT"). Each Management Shareholder shall have the right under the Contracts (Rights of Third Parties) Act 1999 to enforce this clause 3. The Management Shareholders' Representative shall be entitled to receive notices and other communications and take decisions and exercise approvals, consents and other rights under or in connection with this Agreement for and on behalf of the Management Shareholders in accordance with the power of attorney granted to the Management Shareholders' Representative under each Management Shareholder's Agreement.

3.2 The Tag-Along Notice shall identify the number of Subject Shares proposed to be transferred in such Tag-Along Sale including the number of Subject Shares proposed to be sold by the Tag-Along Seller, the identity of the Tag-Along Purchaser, the consideration for which the transfer is proposed to be made, and all other material terms and conditions of the offer by the Tag-Along Purchaser, including the form of the proposed agreement, if any ("TAG-ALONG OFFEr").

3.3 Each Tagging Person shall have the right (a "TAG-ALONG RIGHT"), exercisable by written notice ("TAG-ALONG RESPONSE NOTICE") given to the Tag-Along Seller and the Company within 20 Business Days after its receipt of the Tag-Along Notice (the "TAG-ALONG NOTICE PERIOD"), to request that the Tag-Along Seller include in the proposed Tag-Along Sale the number of Subject Shares held by

11

such Tagging Person as is specified in the Tag-Along Response Notice, provided that:

3.3.1 if the aggregate number of Subject Shares proposed to be sold by the Tag-Along Seller and all Tagging Persons in any such transaction exceeds the number of Subject Shares that can be sold on the terms and conditions set forth in the Tag-Along Notice, then each Tag-Along Seller and each Tagging Person shall be entitled to include in the Tag-Along Sale only up to the lesser of (i) its Tag-Along Portion (defined below) of Subject Shares and (ii) the number of Subject Shares proposed to be sold by it specified in the Tag Along Offer (in the case of the Tag-Along Seller) or in its Tag-Along Response Notice (in the case of a Tagging Person) (the "MAXIMUM ALLOCATION");

3.3.2 if any Subject Shares remain unallocated after applying the cut-back requirement in clause 3.3.1, then such unallocated Subject Shares shall be allocated pro rata based on the total number of Subject Shares owned by each participant that shall have elected to sell more than its Tag-Along Portion, but in no event shall any such participant be required to sell more than its Maximum Allocation; and

3.3.3 for the purposes of this clause 3, "TAG-ALONG PORTION" means, for any Tag-Along Seller or Tagging Person in connection with any Tag-Along Sale, that number of Subject Shares of such Tag-Along Seller or Tagging Person, as the case may be, which is equal to the total number of Subject Shares proposed to be transferred in such Tag-Along Sale as specified in the related Tag-Along Notice, multiplied by a fraction, the numerator of which is the total number of Subject Shares (subject to clause 3.11) owned by the Tag-Along Seller or the Tagging Person, as the case may be, immediately prior to such Tag-Along Sale and the denominator of which is the total number of Subject Shares (subject to clause 3.11) owned by all the Tag-Along Sellers and Tagging Persons immediately prior to such Tag-Along Sale.

3.4 Each Tag-Along Response Notice shall include wire transfer instructions for payment of any cash consideration as part of the purchase price for the Subject Shares to be sold in such Tag-Along Sale. Each Tagging Person that exercises its Tag-Along Rights hereunder shall deliver to the Company (or its designated agent), no later than 5 Business Days prior to the proposed closing date for the Tag-Along Sale, the certificate or certificates representing the Subject Shares of such Tagging Person to be included in the Tag-Along Sale, together with a power-of-attorney authorising the Tag-Along Seller to transfer such Subject Shares on the terms set forth in the Tag-Along Notice. Subject to clause 3.5, delivery of a Tag-Along Response Notice during the Tag-Along Response Period by a Tagging Person shall constitute an irrevocable acceptance of the Tag-Along Offer by such Tagging Persons. Subject to clause 3.5, at the termination of the Tag-Along Notice Period, if a Relevant Shareholder shall not have elected to participate in the Tag-Along Sale by delivery of a Tag-Along Response Notice, such Relevant Shareholder shall be deemed to have waived its rights under this clause with respect to the transfer of its Subject Shares pursuant to such Tag-Along Sale.

12

3.5 In the event of a material change of the Tag-Along Offer (it being understood that any increase of the price payable by more than 5% of the original price shall be deemed a material beneficial change and any decrease of the price payable shall be deemed a material adverse change), the Tag-Along Seller shall (i) (if such change is a material adverse change) give written notice of such change to each Tagging Person, which shall have the right to revoke its election to participate in the Tag-Along Sale by providing written notice to the Company within 5 Business Days of receiving the notice of the change in terms, or (ii) (if such change is a material beneficial change) give written notice of such change to each Relevant Shareholder, which shall have the right to participate in the Tag-Along Sale, in each case, by providing written notice to the Company within 10 Business Days of receiving the notice of the change in terms.

3.6 The Tag-Along Seller shall transfer, on behalf of itself and as attorney for any Tagging Person pursuant to the relevant power-of-attorney in favor of the Tag-Along Seller, the Subject Shares of the Tag-Along Seller and all Tagging Persons elected to be transferred on the terms and conditions consistent with those set forth in the Tag-Along Notice on the closing date specified in the Tag-Along Offer (as may be extended in accordance therewith, the "TAG-ALONG SALE CLOSING DATE").

3.7 Concurrently with the consummation of the Tag-Along Sale, (i) the Tag-Along Seller shall notify the Tagging Persons thereof (including identifying the manner of delivery for any non-cash consideration), and
(ii) the total consideration due to each Tagging Person shall be remitted to such party, with the cash portion of the purchase price paid by wire transfer of immediately available funds in accordance with the wire transfer instructions in the applicable Tag-Along Response Notices.

3.8 If, on the Tag-Along Sale Closing Date, the Tag-Along Sale is not consummated for any reason, (i) the Company (or its designated agent) shall return to each Tagging Person, to the extent previously provided, the limited power-of-attorney together with all certificates representing the Subject Shares that such Tagging Person delivered for transfer pursuant to this clause and any other documents executed by the Tagging Persons in connection with the proposed Tag-Along Sale, and
(ii) no Shareholder Party or Parties shall conduct any transfer of any Shares without again complying with this clause.

3.9 Notwithstanding anything contained in this clause there shall be no liability on the part of the Tag-Along Seller to the Tagging Persons if the transfer of Subject Shares pursuant to this clause is not consummated for any reason. Subject to the terms of any sale agreement executed in connection with a Tag-Along Sale, the decision of whether to effect a transfer of Subject Shares pursuant to this clause by the Tag-Along Seller, or to terminate any such transaction prior to consummation, is in the sole and absolute discretion of the Tag-Along Seller.

3.10 The rights and obligations of Relevant Shareholders to participate in a Tag-Along Sale are subject to the following additional conditions:

3.10.1   upon the consummation of such Tag-Along Sale, all of the
         Tagging Persons will receive the same form and amount of
         consideration per Subject Share, or, if any Tagging Person is
         given an option as to the form

                              13

         and amount of consideration to be received, all Tagging
         Persons will be given the same option;

3.10.2   subject to the terms of any sale agreement executed in
         connection with the Tag-Along Sale, no Tagging Person shall be
         obligated to pay any expenses incurred in connection with any
         unconsummated Tag-Along Sale and each Tagging Person shall be
         obligated to pay only its pro rata share (based on the number
         of Subject Shares transferred by it relative to the total
         number of Subject Shares transferred) of expenses incurred in
         connection with a consummated Tag-Along Sale to the extent
         such expenses are incurred for the benefit of all Tagging
         Persons and are not otherwise paid by the Company or another
         person;

3.10.3   each Tagging Person shall (i) make such representations,
         warranties and covenants and enter into such definitive
         agreements as are customary for transactions of the nature of
         the proposed transfer and as are consistent with, or no less
         favourable or more burdensome than, those applicable to the
         Tag-Along Seller; provided that a Tagging Person shall only be
         required to warrant title to its Subject Shares that are
         subject of the Tag Along Right and its right, power and
         authority to sell such Subject Shares, and the liability of a
         Tagging Person for any warranties in connection with each such
         Tagging Person's title to its Subject Shares and its right,
         power and authority to sell such Subject Shares, shall be
         several but not joint and each such Tagging Person shall not
         be liable for more than the lesser of (A) its pro rata share
         (based on the number of Subject Shares transferred by it
         relative to the total number of Subject Shares transferred) of
         any liability for such warranties and (B) the net proceeds
         received by such Tagging Person in connection with such
         transfer, (ii) otherwise be subject to all of the same
         provisions of the definitive agreements as the Tag-Along
         Seller, and (iii) be required to bear its pro rata share
         (based on the number of Subject Shares transferred by it
         relative to the total number of Subject Shares transferred) of
         any escrows, holdbacks or adjustments in purchase price.

3.11 Subject Shares that have been transferred by a Tag-Along Seller or Tagging Person in a Tag-Along Sale pursuant to the provisions of this clause 3 ("EXCLUDED SHARES") shall not be subject again to the restrictions set forth in this clause 3, nor shall any Shareholder Party holding Excluded Shares be entitled to exercise any rights as a Relevant Shareholder under this clause 3 with respect to such Excluded Shares, and Excluded Shares held by a Tag-Along Seller or any Tagging Person shall not be counted in determining the respective participation rights of such Shareholder Parties in a transfer subject to this clause.

3.12 This clause 3 shall terminate on the date that is thirty-six (36) months after the Effective Date.

         Control on terms no less favourable than those on which the

(iv) to any regulatory authority or rating agency to which such Shareholder Party 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

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

Nothing contained herein shall prevent the use (subject, to the extent possible, to a protective order) of Confidential Information in connection with the assertion or defence of any claim by or against the Company or any Shareholder Party. Additionally, notwithstanding the restrictions in this clause 5, each Shareholder Party and its representatives or other agents may, without prior consent, disclose to any and all persons, without limitations of any kind, the tax treatment and tax structure of the Company and all materials of any kind (including tax opinions or other tax analyses) that are provided to them relating to the tax treatment and tax structure of the Company.

7.1 Clauses 6 and 8.9 of this Agreement shall become effective on and as of the date hereof and together with the Initial Subscription and Shareholders' Agreement (except for Clauses 11.9.1, 11.9.2 and 11.9.3 of the Initial Subscription and Shareholders' Agreement which on and as of the date hereof shall cease to have any force or effect) shall constitute the entire agreement and understanding of the parties hereto and thereto in respect of the subject matter contained herein and therein prior to the Effective Date. The remainder of this Agreement shall become effective on the completion date (the "EFFECTIVE DATE") of the Company's initial public offering of its equity securities pursuant to an effective registration statement (other than on Form F-4 or S-8 or successor form) filed under the Securities Act (the "IPO") and prior to such time shall have no force or effect. If the IPO is abandoned or is not completed for any reason prior to June 30, 2004, this Agreement (other than clauses 6 and 8.9 and this clause 7.1) shall have no force or effect and no party shall have any liability or other obligation to any other party in respect of any of the terms or provisions hereof, provided that, for avoidance of doubt, the Initial Subscription and Shareholders' Agreement, as modified by clauses 6 and 8.9 and this clause 7.1 of this Agreement, shall continue in full force and effect.

Notwithstanding the termination of this Agreement in its entirety or in respect of any party hereto, the terms of clause 5 (Confidentiality) shall survive in accordance with their terms and clauses 1 (Interpretation), 8 (General Provisions), 9 (Notices) and 10 (Governing Law) shall terminate at such time as no other clause or provision of this Agreement is in effect.

8. GENERAL PROVISIONS

8.1 Except as expressly provided otherwise in this Agreement, an amendment or other variation of this Agreement is valid only if it is in writing and signed by or on behalf of the Company (acting with the approval of the Board) and Shareholder Parties holding 75% of the voting power of the Shares (taking into

17

consideration the provisions of Bye-Laws 63-67) held by the Shareholder Parties, provided that any amendment or variation of this Agreement that would adversely affect a Shareholder Party in a disproportionate manner relative to the other Shareholder Parties may not be effected without the consent of such disproportionately effected Shareholder Party. No Manager shall have any right to receive notice of or consent to any amendment or other variation of this Agreement, unless such amendment or variation alters the effect of this clause 8.1 or clause 8.11 to the detriment of such Manager in which case such Manager's prior written consent shall be required. The Company and requisite Shareholder Parties shall be entitled to amend, modify, suspend, rescind or terminate clauses 3 and 6.1 of this Agreement without any notice to or consent of the Management Shareholders, provided that if any such action adversely affects only the Management Shareholders or adversely affects the Management Shareholders in a disproportionate manner relative to the other Shareholder Parties then such action shall not be taken without the prior written consent of Management Shareholders holding a majority of the voting power (taking into consideration the provisions of Bye-Laws 63-67) of the Shares then held by all Management Shareholders.

8.2 The failure to exercise or delay in exercising a right or remedy provided by this Agreement or by law does not constitute a waiver of the right or remedy or a waiver of other rights or remedies. No single or partial exercise of a right or remedy provided by this Agreement or by law prevents further exercise of the right or remedy or the exercise of another right or remedy.

8.3 The parties acknowledge and agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or equity.

8.4 If there is any conflict or inconsistency between the provisions of this Agreement and the Bye-Laws, this Agreement prevails as among the parties to this Agreement.

8.5 The invalidity, illegality or unenforceability of any provision of this Agreement does not affect the continuation in force of the remainder of this Agreement.

8.6 This Agreement may be executed in any number of counterparts each of which when executed and delivered is an original, but all the counterparts together constitute the same document.

8.7 Except as expressly provided otherwise in clause 3.1 of this Agreement, a person who is not a party to this Agreement has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of this Agreement but this does not affect any right or remedy of a third party which exists or is available apart from that Act.

8.8 The parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached,

18

irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or equity.

(i) At any time following the earlier of 180 days after the effective date of the registration statement for the Initial Public Offering and the expiration of the period during which the managing underwriters for the Initial Public Offering shall prohibit the Company from effecting any other public sale or distribution of Ordinary Shares, upon the written request of Holder(s) (other than Company Holders) holding in the aggregate $50 million of Registrable Securities (based on the closing trading price of the applicable Registrable Securities on the last trading day prior to the date of any request) (such requesting Holder(s) being referred to collectively as the "Requesting Holder"), the Requesting Holder may request (each such request, a "Demand Registration") that the Company, at the Requesting Holder's option, either (i) effect the registration under the Securities Act of all or part of the Registrable Securities held by such Requesting Holder and specifying the intended method of disposition thereof, or (ii) effect the registration of all or any of such Requesting Holder's Registrable Securities by filing a registration statement on Form F-3 (or any successor thereto) or other applicable form under the Securities Act which provides for the sale by the Requesting Holder of its Registrable Securities from time to time on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (a "Shelf Registration"), provided that the option to request a Shelf Registration shall be available only following the first anniversary of the effective date of the registration statement for the Initial Public Offering. For each request, the Company will use its reasonable best efforts to effect the registration under the Securities Act of such Registrable Securities and all other Registrable Securities requested by Participating Holders (as defined below) to be included in such Demand Registration in accordance with Section 2(c)(i) below, to the extent necessary to permit the disposition in accordance with such Holder's requests of all Registrable Securities so requested to be registered. The number of Registrable Securities requested to be included in a Demand Registration involving an underwritten offering by the Requesting Holder and any Participating Holders (as defined below) shall be allocated on the same terms and conditions between the firm commitment and the underwriters' over-allotment option in accordance with market practice after consultation with the managing underwriter. The Requesting Holder and the Company shall consult with one another at the beginning of, and throughout, the registration process to coordinate the timing of the proposed offering. Except as otherwise expressly provided herein, if more than one Holder comprises the Requesting Holder for any Demand Registration, failing agreement among such Holders in respect of any decision or action to be taken by the Requesting Holder in connection with such Demand Registration, such decision or action may be taken by majority vote of the number of Registrable Securities requested to be sold by such Holders.

(ii) At any time prior to the effective date of the registration statement relating to a Demand Registration, the Requesting Holder may revoke such request, without liability to any of the Participating Holders, by providing a notice of such revocation to the Company. A request, so revoked, shall be considered to be a Demand Registration unless (w) such revocation arose out of an act or omission of the Company (in which case the Company shall be obligated to pay all Registration Expenses in connection with such revoked request), including without limitation for this purpose any such revocation in response to a material adverse development or disclosure with respect to the business or financial condition of the Company, which development or disclosure was not known to the Requesting Holder otherwise to be charged with a Demand Registration, or (x) such revocation is in response to a Delay Notice (as defined below), or (y) such revocation is in response to a Pricing Notice (as defined below), or (z) the Requesting Holder reimburses the Company for all Registration Expenses of such revoked request. In the case of a Demand Registration for an underwritten offering, the Company agrees to use commercially reasonable efforts to notify the Requesting Holder if the price for any Ordinary Shares or Ordinary Share Equivalent to be registered for sale for the account of the Company is expected to occur outside of any expected pricing

5

range previously disclosed in writing by the Company (or any "pricing" or similar committee formed for such purpose) to the Requesting Holder (each such a notice, together with the pricing notices described in Sections 2(f) and 3(b) below, a "Pricing Notice"); provided that the Company shall not have any such obligation with respect to any registration involving the registration of Ordinary Shares or Ordinary Share Equivalents only for the account of parties other than the Company.

(iii) At any time prior to the effective date of the registration statement relating to a Demand Registration, the Requesting Holder may modify its request, without liability to any of the Participating Holders, by providing a written notice of such modification to the Company and, in a Demand Registration for an underwritten offering, the managing underwriter.

(b) Shelf Registration. The Company shall use its reasonable best efforts to keep any Shelf Registrations continuously effective for the 180-day period beginning on the date on which the Shelf Registration is declared effective. During the period during which the Shelf Registration is effective, the Company shall promptly supplement or make amendments to the Shelf Registration, if required by the Securities Act or if reasonably requested by the Requesting Holder or an underwriter of Registrable Securities, including to reflect any specific plan of distribution or method of sale, and shall use its reasonable best efforts to have such supplements and amendments declared effective, if required, as soon as practicable after filing.

(c) Participation in Demand Registration.

(i) Upon receipt of a Demand Registration by a Requesting Holder, subject to the terms and conditions of this Agreement, the Company will as soon as reasonably possible but not later than 3 Business Days after receipt of such notice, give written notice to all other Holders of Registrable Securities that a Demand Registration has been received. Each such other Holder may request, by delivery of written notice to the Company, that the Company also register the number of such Holder's Registrable Securities specified in such notice (each such other Holder that delivers such notice, a "Participating Holder"), provided that the Company receives such notice during the period (the "Demand Participation Period") expiring at 3 p.m. (EST) on the 10th calendar day following receipt of the Company's notice, provided, further, that, subject to the provisions in the next sentence, in the case of the Names' Trustee, such period shall expire at 3 p.m. (EST) on the 20th Business Day following receipt of the Company's notice (the "Names' Trustee Demand Participation Period"). If such Demand Registration involves an underwritten public offering and compliance with the last proviso of the immediately preceding sentence would, in the opinion of Requesting Holder (after consultation with the managing underwriter), delay such registration and offering, the Requesting Holder may determine that the Names' Trustee shall be subject to the Demand Participation Period for such Demand Registration and shall deliver written notice of such determination to the Company and the Names' Trustee as soon as reasonably practicable after making such determination. If the Requesting Holder so notifies the Company and the Names' Trustee, then (i) the Names' Trustee will be a Participating Holder only in respect of any of its Registrable Securities that the Names' Trustee has requested to be included in such Demand Registration pursuant to a notice delivered to the Company during (but not after the expiration of) the Demand Participation Period and (ii) the provisions of Section 2(c)(ii) shall apply to any of the Registrable Securities that the Names' Trustee has requested to be included in such Demand Registration pursuant to a notice delivered to the Company within the Names' Trustee Demand Participation Period but after the expiration of the Demand Participation Period (the "Additional NT Piggyback

6

Securities"). A Participating Holder may revoke (and, if it does, it shall no longer be deemed a Participating Holder) or modify from time to time its request to participate in a Demand Registration as follows: (i) in the case of a Shelf Registration that does not involve an underwritten offering, by delivery of written notice of such revocation or modification to the Company at any time prior to the effective date of the registration statement relating to such Shelf Registration; or (ii) in the case of a Demand Registration involving an underwritten offering, by delivery of written notice of such revocation or modification to the Company and the managing underwriter, no later than (x) 3
p.m. (EST) on the Business Day immediately prior to the date of printing of the "red herring" preliminary prospectus for such Demand Registration or (y) any time prior to the effective date of the registration statement relating to such Demand Registration, so long as such revocation or modification (when considered together with any other revocations or modifications notified by the Requesting Holder or any other Participating Holders) would not require, in the opinion of the managing underwriter, a revised "red herring" preliminary prospectus to be re-circulated. In the event the Requesting Holder revokes a Demand Registration in accordance with Section 2(a)(ii), each Participating Holder's request to participate in such Demand Registration shall be deemed revoked. After the expiration of the Demand Participation Period and, following any modification of a request by the Requesting Holder in accordance with Section 2(a)(iii) or any modification or revocation of a request by any of the Participating Holders in accordance with this Section 2(c)(i), the Company shall notify the Requesting Holder, the Participating Holders and, in a Demand Registration for an underwritten offering, the managing underwriter, of the number of Registrable Securities to be registered (as modified, as the case may be).

(ii) In connection with any Demand Registration for an underwritten public offering, in the event the Requesting Holder determines pursuant to Section 2(c)(i) above that the Names' Trustee shall be subject to the Demand Participation Period for such Demand Registration, the Names' Trustee may request, by delivery of written notice to the Company within 20 Business Days after the expiration of the related Names' Trustee Demand Participation Period, that the Company effect the registration under the Securities Act of the Additional NT Piggyback Securities for direct resale of such securities by the Names' Trustee (a "Section 2(c)(ii) NT Registration"). The Company shall use its reasonable best efforts to effect the registration under the Securities Act of the Additional NT Piggyback Securities as soon as practicable following receipt of such request from the Names' Trustee, by filing a registration statement on any form for which the Company then qualifies (or which counsel for the Company shall deem appropriate) and which form shall be available for the direct resale of the Additional NT Piggyback Securities. The Company shall, as expeditiously as possible, prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 30 days (or such shorter period which will terminate when all the Additional NT Piggyback Securities covered by such registration statement have been sold) and comply with the provisions of the Securities Act with respect to the direct resale of all the Additional NT Piggyback Securities covered by such registration statement during such period. The Company shall pay all Registration Expenses in connection with such Section 2(c)(ii) NT Registration, including the fees and expenses properly incurred by one firm of legal counsel to the Names' Trustee. At any time prior to the effective date of the registration statement relating to such Section 2(c)(ii) NT Registration, the Names' Trustee may revoke such request by providing a notice of such revocation to the Company. If the Demand Registration or underwritten public offering that triggered the registration obligations of the Company pursuant to this Section 2(c)(ii) is abandoned or not consummated, the Company shall not be under any obligation to effect such Section 2(c)(ii) NT Registration. The provisions of
Section 6(c)(i), (d), (e), (f),

7

(g), (i), (j) and (p) and the last two paragraphs of Section 6 (but none of the other clauses of Section 6) shall apply in connection with any Section 2(c)(ii) NT Registration.

(iii) (A) If the first Demand Registration for an underwritten public offering (the "First Underwritten Demand Registration") has not been requested by a Requesting Holder by the end of the 240th day after the Effective Date (as defined below), the Names' Trustee may request, by delivery of written notice to the Company no later than the end of the 285th day after the Effective Date, that the Company effect the registration under the Securities Act of the number of the Names' Trustee's Registrable Securities specified in such notice, but representing no fewer than 10,000 Ordinary Shares, for direct resale of such securities by the Names' Trustee (a "Section 2(c)(iii) NT Registration", and, together with a "Section 2(c)(ii) NT Registration, a "NT Registration"). The Company shall use its reasonable best efforts to effect the registration under the Securities Act of such securities as soon as practicable following receipt of such request from the Names' Trustee, by filing a registration statement on any form for which the Company then qualifies (or which counsel for the Company shall deem appropriate) and which form shall be available for the direct resale of such securities. The Company shall, as expeditiously as possible, prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 30 days (or such shorter period which will terminate when all the securities covered by such registration statement have been sold) and comply with the provisions of the Securities Act with respect to the direct resale of all the securities covered by such registration statement during such period. The Company shall pay all Registration Expenses in connection with the Section 2(c)(iii) NT Registration, including the fees and expenses properly incurred by one firm of legal counsel to the Names' Trustee. At any time prior to the effective date of the registration statement relating to the Section 2(c)(iii) NT Registration, the Names' Trustee may revoke such request by providing a notice of such revocation to the Company. The provisions of Section 6(c)(i), (d), (e), (f), (g), (i), (j) and (p) and the last two paragraphs of Section 6 (but none of the other clauses of Section 6) shall apply in connection with the Section 2(c)(iii) NT Registration.

(B) If the First Underwritten Demand Registration is requested by a Requesting Holder after the end of the 240th day and prior to the end of the 285th day after the Effective Date and if the Section 2(c)(iii) NT Registration has not yet been requested by the Names' Trustee or has been requested by the Names' Trustee but the registration statement in connection therewith has not yet become effective, such Requesting Holder may determine, by delivery of written notice to the Company and to the Names' Trustee, at the same time of delivery of its Demand Registration notice to the Company in connection with the First Underwritten Demand Registration, to cause the Names' Trustee to participate in such First Underwritten Demand Registration in accordance with the provisions of Section 2(c)(i) (including, if applicable in connection therewith, a Section 2(c)(ii) NT Registration in accordance with the provision of Section 2(c)(ii)) in lieu of a Section 2(c)(iii) NT Registration. If such Requesting Holder so determines, the Company shall not be under any obligation to effect or continue to effect any Section 2(c)(iii) NT Registration and the Names' Trustee's rights under this Section 2(c)(iii) shall terminate, provided that, if such First Underwritten Demand Registration is terminated for any reason, the Names' Trustee's rights under this Section 2(c)(iii) shall be reinstated (whether or not the Names' Trustee had previously requested a Section
2(c)(iii) NT Registration) immediately upon the termination of such registration such that the Names' Trustee shall thereupon have 45 days, from the date on which the Company notifies the Names' Trustee of such termination, to give notice to the Company hereunder (and, for avoidance of doubt, the provisions of this sub-clause (B) shall also apply to such reinstated rights). Any Registration Expenses incurred in connection with

8

a Section 2(c)(iii) NT Registration that is terminated by a Requesting Holder in accordance with this sub-clause (B) shall be included in the Registration Expenses for the First Underwritten Demand Registration (or, if applicable in connection therewith, a Section 2(c)(ii) NT Registration).

(C) Nothing contained in this Section 2(c)(iii) shall be deemed to prohibit the occurrence of or otherwise restrict or delay any Demand Registration, including the First Underwritten Demand Registration.

(d) Registration Statement Form. If any Demand Registration for an underwritten offering is proposed by the Company to be effected by the filing of a registration statement on Form F-3 (or any successor or similar short-form registration statement), and if the managing underwriter shall advise the Company in writing that, in its opinion, the use of another form of registration statement is of material importance to the success of such proposed offering, then such registration shall be effected on such other form.

(e) Effected Demand Registration. A Demand Registration shall not be deemed to have been effected:

(i) if such Demand Registration is revoked by the Requesting Holder and any of the circumstances specified in clauses (w), (x), (y) or (z) of Section 2(a)(ii) apply; or

(ii) if a registration statement with respect thereto has not become effective or not remained effective in compliance with the provisions of the Securities Act for at least 180 days with respect to the disposition of all Registrable Securities covered by such registration statement or until such earlier time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition thereof set forth in such registration request; or

(iii) if the Maximum Offering Size (as defined below) is reduced in accordance with Section 2(f) such that less than 90% of the Registrable Securities sought to be included in such Demand Registration by the Requesting Holder are included.

(f) Priority in Requested Registrations. If a Demand Registration involves an underwritten offering and the managing underwriter advises the Company, the Requesting Holder and the Participating Holders that, in its opinion, the number of securities requested to be included in such registration by such Holders (to the extent any such person has the right to include any such securities in any such registration), together with the number of securities that the Company proposes to sell for its own account (if any), exceeds the maximum number of securities that can be sold without a reasonable expectation of an adverse effect on such offering, including an adverse effect on the price at which such securities can be sold (the "Maximum Offering Size"), then the number of such securities to be included in such registration shall be reduced to such extent, and the Company shall include in such registration up to the Maximum Offering Size:

9

(A) in connection with the First Underwritten Demand Registration (unless a Section 2(c)(iii) NT Registration has been affected prior to or will be affected contemporaneously with the First Underwritten Demand Registration and has not been terminated by the related Requesting Holder in accordance with Section
2(c)(iii)(B)), in which case, sub-clause (B) below shall apply):

(i) first, all the Names' Trustee's Option Shares requested to be included in such registration by the Names' Trustee;

(ii) second, all the Registrable Securities requested to be included in such registration by the Requesting Holder and the Participating Holders (including the Names' Trustee in respect of any of its Registrable Securities other than its Option Shares), pro rata among such Holders on the basis of the number of Registrable Securities then owned by each of such Holders; and

(iii) third, to the extent that the number of Registrable Securities requested to be included in such registration by the Requesting Holder and the Participating Holders (including the Names' Trustee) is, in the aggregate, less than the Maximum Offering Size, the equity securities that the Company proposes to sell for its own account (if any);

(B) in connection with any Demand Registration (unless sub-clause (A)

above applies):

(i) first, all the Registrable Securities requested to be included in such registration by the Requesting Holder and the Participating Holders, pro rata among such Holders on the basis of the number of Registrable Securities then owned by each of such Holders; and

(ii) second, to the extent that the number of Registrable Securities requested to be included in such registration by the Requesting Holder and the Participating Holders is, in the aggregate, less than the Maximum Offering Size, the equity securities that the Company proposes to sell for its own account (if any).

10

(g) Postponements in Requested Registrations. If, upon receipt of a request for a Demand Registration or any NT Registration, the Company is advised in writing by a nationally recognized investment banking firm selected by the Company that, in such firm's opinion, a registration by the Company at the time and on the terms requested would materially and adversely affect any public offering of securities of the Company solely for the account of the Company (a "Company Offering"), in respect of which, in the case of a request for a Demand Registration, the Company has commenced preparations for a registration prior to the receipt of a request for such Demand Registration, and the Company furnishes the Requesting Holder or the Names' Trustee, as the case may be, with a certificate signed by the Chief Executive Officer or Chief Financial Officer of the Company to such effect (a "Transaction Delay Notice") promptly after such request, the Company shall not be required to effect a Demand Registration or any NT Registration until the earliest of (A) 90 days after the completion of such Company Offering, (B) promptly after the abandonment of such Company Offering, or (C) 90 days after the date of the Transaction Delay Notice; provided, however, that in any event the Company shall not be required to effect any Demand Registration or any NT Registration prior to the termination, waiver or reduction of any "blackout period" required by the underwriters to be applicable to the Requesting Holder or the Names' Trustee, as the case may be, in connection with any Company Offering.

(h) Delay Notices. If upon receipt of a request for a Demand Registration or any NT Registration or while a Demand Registration or any NT Registration is pending, the Company determines in its good faith judgment after consultation with its securities counsel that (i) the filing of a registration statement or any amendment thereto would require disclosure of material information which the Company has a bona fide business purpose for preserving as confidential and (ii) a delay as contemplated herein would be likely to reduce the detrimental effect of or would obviate the need for such disclosure, then if the Company provides the Requesting Holder or the Names' Trustee, as the case may be, with written notice (an "Information Delay Notice"; an Information Delay Notice or a Transaction Delay Notice, each, a "Delay Notice") thereof promptly after the Company makes such determination, which shall be made promptly after the receipt of any request, the Company shall not be required to comply with its obligations under Section 2(a) (in case of a Demand Registration) or Section 2(c)(ii) or
2(c)(iii) (in case of any NT Registration thereunder) until the earlier of (A) the date upon which such material information is disclosed to the public or ceases to be material or (B) 90 days after the Company's receipt of such registration request.

(i) Limitations on Delay Notices. The Company shall be entitled to serve only one Delay Notice within any period of 6 consecutive months for a reasonable time specified in the notice but not exceeding 90 days (which period may not be extended or renewed).

(j) Limitations on Demand Registrations.

(i) Other than any Demand Registration to be effected pursuant to a Shelf Registration which does not involve an underwritten offering, for which an unlimited number of Demand Registrations shall be permitted, and subject to
Section 2(e), the Company shall not be obligated to effect more than three Demand Registrations for Blackstone Holders as the Requesting Holder, more than two Demand Registrations for Candover Holders as the Requesting Holder, more than two Demand Registrations for CSFB Holders as the Requesting Holder, more than one Demand Registration for WU plc as the Requesting Holder or more than one Demand Registration for all other Investors and the Names' Trustee combined (the vote of a majority of the Registrable Securities held by such persons being necessary and sufficient to exercise such Demand Registration) as the

11

Requesting Holder. For avoidance of doubt, in any Demand Registration, if the Requesting Holder is comprised of two or more Holders (which are not Affiliates), such Holders shall be entitled, by notice to the Company, to designate which of such Holders shall be deemed to have made the request for such Demand Registration for the purpose of the limitations in this Section 2(j) and, and failing agreement among such Holders, such designation will be made by majority vote of the number of Registrable Securities requested to be sold by such Holders.

(ii) In no event shall the Company be required to effect hereunder more than one Demand Registration involving an underwritten offering within any 6-month period.

(k) Expenses. The Company will pay all Registration Expenses in connection with Demand Registrations.

(l) Selection of Underwriters. If, in any Demand Registration, the Requesting Holder requests that such registration shall be in the form of an underwritten offering, such offering shall be an underwritten offering and (x) the Requesting Holder, in consultation with the Company, shall have the right to select the managing underwriter and lead manager to administer the offering and, failing agreement among the Holders (if more than one) comprising the Requesting Holder, the managing underwriter and lead manager shall be selected by plurality vote of the number of Registrable Securities requested to be sold by such Holders (in each case, subject to the approval of the Company (such approval not to be unreasonably withheld)) and (y) the Company, in consultation with the Requesting Holder, shall have the right to select any co-underwriters. The Company, the Requesting Holder and the Participating Holders shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting, as well as all other documents reasonable and customary in similar offerings, including, without limitation, custody agreements, powers of attorney, and indemnification agreements (subject to the limitation that any obligations of the Holders to indemnify any other person shall be limited as described in Section 7(b) hereof).

3. Incidental Registration.

(a) Rights to Include Registrable Securities.

(i) If the Company proposes to register any of its equity securities under the Securities Act (other than a registration on Form S-8 or F-4 or any successor or similar forms or any registration relating to employee benefit plans), whether or not for sale for its own account, then the Company will, as soon as reasonably practicable but no later than 10 Business Days prior to the filing date of the registration statement relating to such registration and subject to the terms and conditions of this Section 3, give written notice to each Holder of its intention to register its equity securities and offer each Holder the opportunity to include such Holder's Registrable Securities in such registration statement. Each Holder may request, by delivery of written notice to the Company, that the Company also register the number of such Holders' Registrable Securities specified in such notice (each such Holder that delivers such notice, a "Selling Holder"), provided that such notice is received by the Company during the period (the "Incidental Participation Period") expiring at 3
p.m. (EST) on the 10th calendar day following receipt of the Company's notice, provided, further, that, subject to the provisions in the next sentence, in the case of the Names' Trustee, such period shall expire at 3 p.m. (EST) on the 20th Business Day following receipt of the Company's notice (the "Names' Trustee Incidental Participation Period"). If compliance with the last proviso of the immediately preceding sentence would, in the opinion of

12

Company, delay such registration and offering, the Company may determine that the Names' Trustee shall be subject to the Incidental Participation Period for such registration and shall deliver written notice of such determination to the Names' Trustee as soon as reasonably practicable after making such determination. If the Company so notifies the Names' Trustee, then (i) the Names' Trustee will be a Selling Holder only in respect of any of its Registrable Securities that the Names' Trustee has requested to be included in such registration pursuant to a notice delivered to the Company during (but not after the expiration of) the Incidental Participation Period and (ii) the provisions of Section 3(a)(iii) shall apply to any of the Registrable Securities that the Names' Trustee has requested to be included in such registration pursuant to a notice delivered to the Company within the Names' Trustee Incidental Participation Period but after the expiration of the Incidental Participation Period (the "Additional NT Incidental Securities"). A Selling Holder may revoke (and, if it does, it shall no longer be deemed a Selling Holder) or modify from time to time its request to participate in a registration under this Section 3 as follows: (i) in the case of a registration statement on Form F-3 (or any successor thereto) or other applicable form under the Securities Act which provides for the sale of Ordinary Shares or Ordinary Share Equivalents from time to time on a delayed or continuous basis pursuant to Rule 415 under the Securities Act and that does not involve an underwritten offering, by delivery of written notice of such revocation or modification to the Company at any time prior to the effective date of the registration statement relating to such registration; or (ii) in the case of a registration involving an underwritten offering, by delivery of written notice of such revocation or modification to the Company and the managing underwriter, no later than (x) 3
p.m. (EST) on the Business Day immediately prior to the date of printing of the "red herring" preliminary prospectus for such registration or (y) any time prior to the effective date of the registration statement relating to such registration, so long as such revocation or modification (when considered together with any other revocations or modifications notified by any other Selling Holders) would not require, in the opinion of the managing underwriter, a revised "red herring" preliminary prospectus to be re-circulated.

(ii) The Company shall use its reasonable best efforts to effect the proposed registration under the Securities Act of all Registrable Securities which the Selling Holders have requested the Company to register (as modified, as the case may be), provided that (x) if such registration involves an underwritten offering, each Selling Holder must sell its Registrable Securities to the underwriters selected by the Company on the same terms and conditions as apply to the Company, including the terms of the allocation of Registrable Securities included in such registration between the firm commitment and the underwriters' over-allotment option, which shall be in accordance with market practice after consultation with the underwriters (except that indemnification obligations of any Selling Holder shall be limited to those obligations set forth in Section 7(b) hereof) and (y) if, at any time after giving written notice of its intention to register any securities pursuant to Section 3(a)(i) and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register such securities, the Company shall give written notice to each Selling Holder and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration. A registration effected under this Section 3 shall not relieve the Company of its obligations to effect any Demand Registration under Section 2 hereof. The Company will pay all Registration Expenses in connection with each registration of Registrable Securities pursuant to this Section 3.

(iii) In connection with any registration by the Company pursuant to
Section 3(a)(i) above, in the event the Company determines that the Names' Trustee shall be subject to the Incidental Participation Period for such registration, the Names' Trustee may

13

request, by delivery of written notice to the Company within 20 Business Days after the expiration of the related Names' Trustee Incidental Participation Period, that the Company effect the registration under the Securities Act of the Additional NT Incidental Securities for direct resale of such securities by the Names' Trustee. The Company shall use its reasonable best efforts to effect the registration under the Securities Act of the Additional NT Incidental Securities as soon as practicable following receipt of such request from the Names' Trustee, by filing a registration statement on any form for which the Company then qualifies (or which counsel for the Company shall deem appropriate) and which form shall be available for the direct resale of the Additional NT Incidental Securities. The Company shall, as expeditiously as possible, prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 30 days (or such shorter period which will terminate when all the Additional NT Incidental Securities covered by such registration statement have been sold) and comply with the provisions of the Securities Act with respect to the direct resale of all the Additional NT Incidental Securities covered by such registration statement during such period. The Company shall pay all Registration Expenses in connection with such registration, including the reasonable fees and expenses of one firm of legal counsel to the Names' Trustee. At any time prior to the effective date of the registration statement relating to such registration, the Names' Trustee may revoke such request by providing a notice of such revocation to the Company. If the registration or offering by the Company that triggered the registration obligations of the Company pursuant to this Section 3(a)(iii) is abandoned or not consummated, the Company shall not be under any obligation to effect any registration under this Section 3(a)(iii). Clauses (c)(i), (d), (e), (f), (g), (i), (j) and (p) and the last two paragraphs of Section 6 (but none of the other clauses of Section 6) shall apply in connection with any registration under this Section 3(a)(iii).

(iv) Notwithstanding the foregoing provisions of this Section 3(a), the rights of each Holder to include its Registrable Securities in a registration conducted by the Company (under the Prior Agreement or hereunder) shall not apply in the case of the Initial Public Offering, provided that the Initial Public Offering is completed prior to June 30, 2004.

(b) Priority in Incidental Registrations.

(i) Subject to paragraph (ii) below, if a registration pursuant to this
Section 3 involves an underwritten offering and the managing underwriter advises the Company that, in its opinion, the number of equity securities (including Registrable Securities requested to be included in such offering by the Selling Holders) that the Company and the Selling Holders intend to include in such registration exceeds the Maximum Offering Size, the number of such securities to be included in such registration shall be reduced to such extent, and the Company will include in such registration up to the Maximum Offering Size as follows:

(A) first, all the equity securities the Company proposes to sell for its own account in such registration; and

(B) second, to the extent that the number of equity securities included in such registration by the Company for its own account is less than the Maximum Offering Size, the aggregate number of Registrable Securities requested to be included in such registration by the Selling Holders, allocated pro rata among the Selling Holders on

14

the basis of the number of Registrable Securities then owned by each of the Selling Holders.

(ii) Subject to the provisions of Section 9(o) below, if any holder(s) of Ordinary Shares, Ordinary Share Equivalents or other equity securities of the Company ("Other Registrable Securities") other than a Holder (each, a "Non-Party Requesting Holder") makes a requested or demand registration, such requested or demand registration involves an underwritten offering and the managing underwriter advises the Company that, in its opinion, the number of securities requested to be included in such registration (including all Registrable Securities requested to be included in such registration by the Holders and all Other Registrable Securities requested to be included in such registration by Non-Party Requesting Holders) exceeds the Maximum Offering Size, the number of such securities to be included in such registration shall be reduced to such extent, and the Company shall include in such registration such number of securities up to the Maximum Offering Size, as follows: (A) first, the number of Registrable Securities requested to be included in such registration by the Holders shall be limited to such extent, and shall be allocated pro rata among them on the basis of the relative number of Registrable Securities then owned by such Holders, provided that any such amount thereby allocated to any such Holder that exceeds such Holder's request shall be reallocated to the other remaining Holders, and (B) second, to the extent that the number of Registrable Securities which the Holders have requested to be included in such registration is less than the Maximum Offering Size, the number of Other Registrable Securities requested to be included in such registration by the Non-Party Requesting Holder and all other holders thereof (collectively, "Non-Party Holders"), provided that the number of Registrable Securities that may be registered by Non-Party Holders shall be limited to such extent, and, subject to any rights of Non-Party Holders, shall be allocated pro rata among all Non-Party Holders on the basis of the relative number of Other Registrable Securities then owned by such Non-Party Holders.

4. Holdback Agreements.

(a) If any registration of Registrable Securities shall be effected in connection with an underwritten public offering (including, for avoidance of doubt, the Initial Public Offering), each Holder agrees (i) not to effect any public sale or distribution, including any sale pursuant to Rule 144 under the Securities Act, of any Ordinary Shares, Ordinary Share Equivalents or other equity securities of the Company or of any securities convertible into or exchangeable or exercisable for Ordinary Shares, Ordinary Share Equivalents or any other equity securities of the Company (except for a direct resale of securities by the Names' Trustee pursuant to an effective registration statement under the Securities Act in accordance with the provisions of Section 2(c)(ii),
Section 2(c)(iii) or Section 3(a)(iii), as the case may be); and (ii) if such Holder (together with any Affiliate of such Holder) holds 5% or more of the Ordinary Shares (on a fully-diluted basis, taking into account all vested and exercisable options, warrants or rights to acquire any Ordinary Shares and any securities immediately convertible into or exchangeable or exercisable for Ordinary Shares), not to transfer, by way of a dividend, distribution or comparable transfer to any shareholder, member, partner, limited partner or beneficiary (as the case may be) of such Holder, any Ordinary Shares, Ordinary Share Equivalents or other equity securities of the Company or of any securities convertible into or exchangeable or exercisable for Ordinary Shares, Ordinary Share Equivalents or any other equity securities of the Company, in each case under clause (i) or (ii), other than as part of such underwritten public offering pursuant to an effective registration statement, commencing on the date that is 5 days prior to the anticipated date of the printing of the "red herring" preliminary prospectus for the road show for such offering (which date shall be specified in a written notice to the Holders from the Company) and

15

continuing for such period of time as the managing underwriter and the Company may agree (not to exceed, in the case of the Initial Public Offering, 180 days, or in the case of any other underwritten public offering, 90 days, beginning on the closing date of the sale of securities in such offering pursuant to an effective registration statement); provided, however, that:

(i) all Company Holders and all other persons with registration rights (whether or not pursuant to this Agreement) enter into similar arrangements having terms and conditions that are no more favorable to such persons than those set forth in this Section 4(a);

(ii) this Section 4(a) shall not apply to any securities of the Company acquired by any Holder in the Initial Public Offering or any other underwritten public offering, or acquired by any Holder on the open market after the Initial Public Offering or other underwritten public offering of equity securities of the Company;

(iii) this Section 4(a) shall not be deemed to restrict any Investor or any of its Affiliates from engaging in any brokerage, investment advisory, financial advisory, anti-raid advisory, merger advisory, financing, asset management, trading, market making, arbitrage and other similar activities conducted in the ordinary course of its or such Affiliates business;

(iv) notwithstanding the foregoing, in the event that the Company and the underwriters agree to release any Company securities from this
Section 4(a) or any similar provision in another arrangement ("Holdback Provisions"), the Registrable Securities of the Holders shall be released from Holdback Provisions on a pro-rata basis with such other Company securities (based upon the number of shares of Company securities released by the Company and the underwriter relative to the aggregate number of Company securities held by each Holder); and

(v) notwithstanding the foregoing, the obligations described in this
Section 4(a) shall not apply to a registration relating solely to employee benefit plans on Form S-8 or similar forms which may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form F-4 or Form N-14 or similar forms which may be promulgated in the future.

(b) Restrictions on Public Sale by the Company and Others. If any registration of Registrable Securities shall be made in connection with an underwritten public offering (including, for avoidance of doubt, the Initial Public Offering), the Company agrees (i) not to effect any public sale or distribution of any Ordinary Shares, Ordinary Share Equivalents or other equity securities of the Company or of any security convertible into or exchangeable or exercisable for any Ordinary Shares, Ordinary Share Equivalents or other equity securities of the Company (other than in connection with an employee stock option or other benefit plan or as part of such underwritten public offering pursuant to an effective registration statement), commencing on the date that is 5 days prior to the anticipated date of the printing of the "red herring" preliminary prospectus for the road show for such offering and continuing for 180 days beginning on the closing date of the sale of securities in such underwritten public offering pursuant to an effective registration statement (unless otherwise agreed by the Holders of a majority of the Registrable Securities included in such underwritten public offering) and (ii) that any agreement entered into after the date of this

16

Agreement pursuant to which the Company issues or agrees to issue any privately placed Ordinary Shares, Ordinary Share Equivalents or other equity securities shall contain a provision under which holders of such securities agree not to effect any public sale or distribution of any such securities during the period referred to in the foregoing clause (i), including any sale pursuant to Rule 144 under the Securities Act (other than, if permitted, as part of such underwritten public offering pursuant to an effective registration statement).

5. Permitted Distributees.

(a) Except as otherwise expressly provided in this Section 5, a Permitted Distributee shall not be a Holder in respect of any Ordinary Shares or Ordinary Share Equivalents distributed to such Permitted Distributee by a Holder pursuant to a Permitted Distribution or otherwise have any rights or obligations under this Agreement. No person to which any Permitted Distributee transfers any of its Ordinary Shares or Ordinary Share Equivalents so distributed to it shall be deemed a Holder or otherwise have any rights or obligations under this Agreement unless (i) prior to such transfer such Permitted Transferee itself has rights or obligations under this Agreement in accordance with this Section 5 and (ii) such Transferee is an Affiliate of such Permitted Distributee.

(b) If (x) each Permitted Distributee that receives any Ordinary Shares or Ordinary Share Equivalents from a Holder in a Permitted Distribution is an Affiliate or Associated Person of such Holder or (y) a Permitted Distributee that receives any Ordinary Shares or Ordinary Share Equivalents from a Holder in a Permitted Distribution is an Affiliate of such Holder and holds (when aggregated with the Ordinary Shares or Ordinary Share Equivalents held by such Holder and each Affiliate of such Holder) 5% or more of the Ordinary Shares (on a fully-diluted basis, taking into account all vested and exercisable options, warrants or rights to acquire any Ordinary Shares and any securities immediately convertible into or exchangeable or exercisable for Ordinary Shares) after such Permitted Distribution; (each such Permitted Distributee under clause (x) or
(y), an "Affiliated Permitted Distributee"), then, each Affiliated Permitted Distributee, by accepting any Ordinary Shares or Ordinary Share Equivalents in such Permitted Distribution, will be deemed to have agreed (and such Affiliated Permitted Distributee shall, on request of the Company, confirm such agreement in writing) that the terms of Section 4(a) and Section 9 (other than clause (o) of Section 9) shall apply to such Affiliated Permitted Distributee.

(c) If a Holder is participating in a Shelf Registration, either as the Requesting Holder of such Shelf Registration or as a Participating Holder or Selling Holder in respect of such Shelf Registration, or if a Shelf Registration otherwise has been implemented and is effective under the Securities Act, then such Holder shall be entitled to add its Permitted Distributees as selling security holders under such Shelf Registration (excluding, however, as sellers pursuant to an underwritten offering) in respect of any Registrable Securities that have been or will be transferred by such Requesting Holder to such Permitted Distributees pursuant to a Permitted Distribution and the Company shall, any time after the date that such Shelf Registration has become effective under the Securities Act and upon return of the legended securities (either by such Holder or, after such Permitted Distribution, any Permitted Distributee), promptly remove (or cause to be removed) the legends remaining on the certificates representing the shares to be sold under such Shelf Registration. Each such Permitted Distributee that is added or is proposed to be added as a selling security holder under such Shelf Registration, by accepting any Registrable Securities in such Permitted Distribution, will be deemed to have agreed (and such Permitted Distributee shall, on request of the Company, confirm such agreement in writing) that (i) such Permitted Distributee shall be entitled to the rights and benefits of the provisions of Section 6 which are applicable to such Shelf Registration (excluding, however, clauses (a), (c)(ii), (d), (k),
(l), (m), (n), (o), (p)(ii) and (iii), (q), (r), (s) and (t) thereof), the Company hereby

17

acknowledging and agreeing to such rights, and (ii) the terms of the last two paragraphs of Section 6 and Sections 7, 8 and 9 (other than clause (o) of
Section 9) shall apply to such Permitted Distributee.

6. Registration Procedures.

If and whenever the Company is required to use its reasonable best efforts to effect or cause the registration of any Registrable Securities under the Securities Act as provided in this Agreement the Company will, as expeditiously as possible (except as otherwise provided in Sections 2(c)(ii), 2(c)(iii) and
3(a)(iii)):

(g) use its reasonable best efforts to prevent the issuance of and obtain the withdrawal of any stop order suspending the effectiveness of a registration statement relating to the Registrable Securities or of any order preventing or suspending the use of any preliminary or final prospectus at the earliest practicable moment;

(h) if requested by the managing underwriters or any Holder (other than any Company Holder) that is participating in such registration, immediately incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter(s) and such Holders agree should be included therein relating to the plan of distribution with respect to such Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being sold to such underwriters, the purchase price being paid therefor by such underwriters and with respect to any other terms of the underwritten (or best efforts underwritten) offering of the Registrable Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as notified of the matters to be incorporated to such prospectus supplement or post-effective amendment;

(i) cooperate with each Holder that is participating in such registration and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends and enable such Registrable Securities to be in such denominations and registered in such names as the managing underwriters may request at least three business days prior to any sale of the Registrable Securities to the underwriters;

(j) use its reasonable best efforts to cause all such Registrable Securities to be listed on a national securities exchange or quotation system, and on each securities

(m) use its reasonable best efforts to obtain (i) an opinion or opinions of counsel to the Company in customary form and (ii) a "cold comfort" letter or letters from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by opinions and "cold comfort" letters as the Holders (other than the Company Holders) that are participating in such registration or the underwriter, if any, requests, in each case, addressed to the underwriters;

It shall be a condition precedent to the obligation of the Company to take any action pursuant to this Agreement in respect of the securities which are to be registered at the request of any Holder that such Holder shall furnish to the Company such information regarding the securities held by such Holder and its Affiliates and the intended method of disposition thereof as the Company shall reasonably request in connection with such registration.

Each Holder that is participating in a registration agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 6(f) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Holder receives the copies of the prospectus supplement or amendment contemplated by Section 6(f) hereof, and, if so directed by the Company, such Holder will deliver to the Company (at the Company's expense) all copies, other than permanent file copies, then in such Holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the period mentioned in Section 6(b) hereof shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 6(f) hereof to and including the date when such Holder shall have received the copies of the prospectus supplement or amendment contemplated by Section 6(f) hereof.

7. Indemnification.

(a) Indemnification by the Company. In the event of any registration of any Registrable Securities under the Securities Act pursuant to Section 2 or 3 hereof, the Company will, and it hereby does, indemnify and hold harmless, to the full extent permitted

by law, each Holder, its directors, officers, employees, stockholders, general partners, limited partners, members, advisory directors and managing directors (and directors, officers, stockholders, general partners, limited partners, members, advisory directors, managing directors and controlling persons thereof), in the case of the Names' Trustee, the Names Trust Beneficiaries, each other person who participates as an underwriter in the offering or sale of such securities and each other person, if any, who controls, is controlled by or is under common control with any Holder or any such underwriter within the meaning of the Securities Act, against any and all losses, claims, damages or liabilities, joint or several, and expenses (including any amounts paid in any settlement effected with the Company's consent) to which such Holder, any such director, or officer, employee, stockholder, general or limited partner, member, or advisory or managing director, any Names Trust Beneficiary or any such underwriter or controlling person may become subject under the Securities Act, state securities or blue sky laws, common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) or expenses arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto or (ii) 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 (in the case of a prospectus, in light of the circumstances under which they are made), and the Company will reimburse each Holder and each such director, officer, employee, general partner, limited partner, advisory director, managing director, Names Trust Beneficiary or underwriter and controlling person for any legal or any other expenses reasonably incurred by them as such expenses are incurred in connection with investigating or defending such loss, claim, liability, action or proceeding; provided that the Company shall not be liable with respect to any individual Holder in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or amendment or supplement thereto or in any such preliminary, final or summary prospectus in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by such Holder or its director, officer, employee, stockholder, general or limited partner, managing director, Names Trust Beneficiary or underwriter, as applicable, specifically stating that it is for use in the preparation thereof; provided, further, however, that the Company shall not be required to indemnify any such person if such untrue statement or omission or alleged untrue statement or omission was contained or made in any preliminary prospectus and corrected in the final prospectus or any amendment or supplement thereto and the final prospectus does not contain any other untrue statement or omission or alleged untrue statement or omission of a material fact that was the subject matter of the related proceeding and any such loss, liability, claim, damage or expense suffered or incurred by such indemnified person resulted from any action, claim or suit by any person who purchased Registrable Securities which are the subject thereof from such indemnified person and it is established in the related proceeding that such indemnified person failed to deliver or provide a copy of the final prospectus (as amended or supplemented) to such person with or prior to the confirmation of the sale of such Registrable Securities sold to such person if required by applicable law, unless such failure to deliver or provide a copy of the final prospectus (as amended or supplemented) was a result of noncompliance by the Company with this Section 7 or as a result of the failure of the Company to provide such final prospectus. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of each Holder or any such director, officer, employee, general partner, limited partner, managing director, Names Trust

22

Beneficiary, underwriter or controlling person and shall survive the transfer of such securities by any Holder.

(b) Indemnification by Holders and Underwriters. In the event of any registration of any Registrable Securities under the Securities Act pursuant to
Section 2 or 3 hereof, each Holder selling such Registrable Securities in such registration and any underwriter will, and they hereby do, indemnify and hold harmless (in the same manner and to the same extent as set forth in subdivision
(a) of this Section 7) the Company and its directors, officers, employees and controlling persons against any and all losses, claims, damages or liabilities, joint or several, and expenses (including any amounts paid in any settlement effected with the consent of the applicable Holder and any underwriter) to which the Company and its directors, officers, employees and controlling persons may become subject under the Securities Act, state securities or blue sky laws, common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) or expenses arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto or (ii) 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 (in the case of a prospectus, in light of the circumstances under which they are made), and the applicable Holder and any underwriter will reimburse the Company and its directors, officers, employees and controlling persons for any legal or any other expenses reasonably incurred by them to the extent that such expenses are incurred in connection with investigating or defending such loss, claim, liability, action or proceeding; provided that each such Holder or any underwriter, as applicable, shall only be liable in any case described in this Section 7(b) if and to the extent that the relevant loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or amendment or supplement thereto or in any such preliminary, final or summary prospectus in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by such particular Holder or such underwriter, as applicable, specifically stating that such instrument is for use in the preparation of such registration statement, and provided, further, that any liability of any Holder under (or which could have been brought under) this Section 7 shall be several and not joint with any other person, provided, further, however, that such Holder or underwriter shall not be required to indemnify the Company if such untrue statement or omission or alleged untrue statement or omission was contained or made in any preliminary prospectus and corrected in the final prospectus or any amendment or supplement thereto and the final prospectus does not contain any other untrue statement or omission or alleged untrue statement or omission of a material fact that was the subject matter of the related proceeding and any such loss, liability, claim, damage or expense suffered or incurred by the Company resulted from any action, claim or suit by any person who purchased Registrable Securities which are the subject thereof from the Company and it is established in the related proceeding that the Company failed to deliver or provide a copy of the final prospectus (as amended or supplemented) to such person with or prior to the confirmation of the sale of such Registrable Securities sold to such person if required by applicable law, unless such failure to deliver or provide a copy of the final prospectus (as amended or supplemented) was a result of noncompliance by the Holder or any underwriter with this Section 7 or as a result of the failure of the Holder or any underwriter to provide such final prospectus. No Holder shall be liable for any claims brought, or that could have been brought, under this Section 7 for any amounts exceeding in the aggregate the net purchase price proceeds received by that Holder on the sale of the

23

Registrable Securities being sold pursuant to such registration statement or prospectus by such Holder.

(c) Notices of Claims, Etc. Promptly after receipt by an indemnified party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this
Section 7, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, promptly give written notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding subsections of this Section 7, except to the extent that the indemnifying party is actually materially prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties exists in respect of such claim, the indemnifying party will be entitled to participate in and, jointly with any other indemnifying party similarly notified, to assume the defense thereof, to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defense thereof or a court of competent jurisdiction determines that the indemnifying party is not vigorously defending such action or proceeding. An indemnifying party will not be subject to any liability for any settlement made without its consent (which consent shall not be unreasonably withheld). No indemnifying party will consent to entry of any judgment or enter into any settlement of any pending or threatened proceeding which (i) does not include as an unconditional term thereof the giving by the claimant or plaintiff to all indemnified parties of a release from all liability in respect to such claim or litigation, (ii) involves the imposition of equitable remedies or the imposition of any non-financial obligations on such indemnified party or (iii) does not otherwise adversely affect such indemnified party, other than as a result of the imposition of financial obligations for which such indemnified party will be indemnified hereunder. Notwithstanding anything to the contrary contained herein, an indemnifying party will not be obligated to pay the fees and expenses of more than one counsel (together with appropriate local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel or counsels (together with the fees of appropriate local counsel).

(d) Contribution. If the indemnification provided for in this Section 7 is unavailable to an indemnified party under Section 7(a) or Section 7(b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each applicable 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 losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, and the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the indemnifying party on the one hand and of the indemnified party on the other shall be

24

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 indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Sections 7(a) and 7(b), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 7(d), no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities sold by such Holder and distributed to the public were offered to the public exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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.

(e) Other Indemnification. Indemnification similar to that specified in Sections 7(a) and 7(b) (with appropriate modifications) shall be given by the Company and each Holder with respect to any required registration or other qualification of securities under any law or with any Governmental Entity other than as required by the Securities Act.

(f) Non-Exclusivity. The obligations of the parties under this Section 7 shall be in addition to any liability, which any party may otherwise have to any other party, subject to the aggregate limits described in the last sentence of
Section 7(b).

(g) Indemnification Payments. The indemnification and contribution required by Sections 7(a), 7(b) and 7(d) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred.

8. Information to be Furnished by the Holders. EACH HOLDER SHALL FURNISH TO
THE COMPANY SUCH INFORMATION AS THE COMPANY MAY REASONABLY REQUEST AND AS SHALL BE REQUIRED IN CONNECTION WITH THE REGISTRATION AND RELATED PROCEEDINGS REFERRED TO HEREIN. IF SUCH HOLDER FAILS TO PROVIDE THE COMPANY WITH SUCH INFORMATION WITHIN TWO WEEKS OF RECEIPT OF THE COMPANY'S REQUEST, THE COMPANY'S OBLIGATIONS HEREUNDER WITH RESPECT TO SUCH HOLDER'S REGISTRABLE SECURITIES SHALL BE SUSPENDED UNTIL SUCH HOLDER PROVIDES SUCH INFORMATION.

9. Miscellaneous.

(a) Remedies. The Company and each Holder acknowledge and agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms hereof and immediate injunctive relief,

25

without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or equity.

(b) Entire Agreement. This Agreement, together with the Shareholders' Agreement and each Management Shareholder's Agreement, constitute the entire agreement and understanding of the parties hereto in respect of the subject matter contained herein, and there are no restrictions, promises, representations, warranties, covenants, or undertakings with respect to the subject matter hereof, other than those expressly set forth or referred to herein or therein. This Agreement supersedes all prior agreements and understandings among the parties hereto with respect to the subject matter hereof (other than the Shareholders' Agreement and each Management Shareholder's Agreement).

Each of the parties to this Agreement submits to the non-exclusive jurisdiction of those courts, including but not limited to the in personam and subject matter jurisdiction of those courts, waives any objections to such jurisdiction on the grounds of venue or forum non conveniens, the absence of in personam or subject matter jurisdiction and any similar grounds, consents to service of process by mail (in accordance with
Section 9(c)) or any other manner permitted by law, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement.

(g) Severability. The invalidity, illegality or unenforceability of one or more of the provisions of this Agreement in any jurisdiction shall not affect the validity, legality or enforceability of the remainder of this Agreement in such jurisdiction or the validity, legality or enforceability of this Agreement, including any such provision, in any other jurisdiction, it being intended that all rights and obligations of the parties hereunder shall be enforceable to the fullest extent permitted by law.

(h) Other Agreements. Nothing contained in this Agreement shall be deemed to be a waiver of, or release from, any obligations any party hereto may have under, or any restrictions on the transfer of Registrable Securities or other securities of the Company imposed by, any other agreement.

(i) Assignment; Successors and Assigns. The registration rights arising under this Agreement may not be assigned by any Holder other than to a person who would qualify as a Transferee of such Holder. Subject to the foregoing sentence and the provisions of Section 5 (with respect to Permitted Distributees), the provisions of this Agreement shall be binding upon and accrue to the benefit of the parties hereto and their respective heirs, successors and permitted assigns and the provisions of this Agreement which are for the benefit of the Holders shall also be for the benefit of and enforceable by any Transferee

27

(whether or not any express assignment shall have been made); provided that (i)
each Transferee and each Permitted Distributee which is intended to be bound by this Agreement in accordance with the provisions of Section 5 shall be required to execute and deliver a written agreement to be bound by the terms and conditions of this Agreement applicable to such Transferee in a form reasonably satisfactory to the Company and (ii) the Company shall require each Company Holder to execute and deliver a Management Shareholder's Agreement, which contains a provision whereby such Company Holder agrees to be bound by the terms and conditions of this Agreement applicable to such Company Holder. Each Holder shall have the exclusive option to determine which rights and obligations shall be assigned to any Transferee (but no such option will limit the rights of any other Holders hereunder). The parties acknowledge for the purposes of this Agreement and the Shareholders' Agreement that WU plc may grant security over the Ordinary Shares and the Options held by WU plc and may assign its rights arising under this Agreement by way of security provided that, before the grant of the security and security assignment, the chargee shall have executed an undertaking in the form of a deed (in terms reasonably satisfactory to the Company) for the benefit of the Company and the other parties to this Agreement and the Shareholders' Agreement that the chargee (or any other person nominated by the chargee as the person to whom the Ordinary Shares and/or rights under this Agreement are to be transferred) will execute a deed of adherence to the Shareholders' Agreement substantially in the form attached thereto and a written agreement to be bound by the terms and conditions of this Agreement in the form set out in a schedule to the undertaking of the chargee referred to above prior to, or at the time, of being registered as the holder of such Ordinary Shares whereupon the chargee (or such person) shall be bound by, and have the benefit of the Shareholders' Agreement and this Agreement.

(j) Amendments, Waivers. This Agreement may not be amended, modified or supplemented and no waivers of or consents to departures from the provisions hereof may be given unless consented to in writing by Holders (other than Company Holders or Permitted Distributees, in each case, subject to the applicable provisions of Section 9(p) below) holding 75% of the total number of Registrable Securities then held by all such Holders; provided that any amendment or variation of this Agreement that would adversely affect a Holder (other than Company Holders or Permitted Distributees, in each case, subject to the applicable provisions of Section 9(p) below) in a disproportionate manner relative to the other Holders may not be effected without the consent of such disproportionately affected Holder.

(k) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which shall constitute one and the same Agreement.

(l) Limited Liability. Notwithstanding any other provision of this Agreement, neither the current or future members, general partners, limited partners, managing directors or advisors, or any current or future directors, officers or employees of any such members, general partners, limited partners, managing directors or advisors, of any Investor shall have any personal liability for performance of any obligation of such Investor under this Agreement. The parties to this Agreement acknowledge that the Names' Trustee is a party to this Agreement solely in its capacity as trustee of the Part A Trust Fund of the Names Trust and, accordingly, (x) the Names' Trustee shall be liable to satisfy its obligations under this Agreement, including, without limitation, any obligations or liabilities arising under the indemnity provisions of Section 7(b) or arising in connection with any default by the Names' Trustee under this Agreement, only to the extent of the assets held from time to time by the Names' Trustee as trustee of the Part A Trust Fund of the Names Trust in

28

accordance with the terms of the declaration of trust governing the Names Trust ("Names Trust Assets") and (y) no recourse shall be had to (I) any assets other than the Names Trust Assets, including, any of the assets held by the Names' Trustee as trustee, co-trustee or nominee of a trust other than the Names Trust, as owner in its individual capacity or in any way other than as trustee of the Part A Trust Fund of the Names Trust or (II) the Names' Trustee for any cash, securities or other assets that have been distributed by the Names' Trustee to the Names Trust Beneficiaries as beneficiaries of the Names Trust.

(m) Adjustments Affecting Registrable Securities. The Company will not take any action, or permit any change to occur, with respect to the Registrable Securities which would adversely affect the ability of any Holder (other than any Company Holder or any Permitted Distributee, subject, in each case, to the terms of Section 9(p) below) to include such Registrable Securities in a registration undertaken pursuant to this Agreement.

(n) Rule 144. If the Company is subject to the requirements of Section 13, 14 or 15(d) of the Exchange Act, the Company covenants that it will file any reports required to be filed by it under the Securities Act and the Exchange Act (or, if the Company is not required to file such reports, it will, make publicly available such information, as described in Rule 144) and it will take such further action as any Holder may reasonably request, so as to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (ii) any successor or similar rule or regulation hereafter adopted by the SEC. Upon the request of any Holder, the Company will deliver to such Holder (w) a written statement as to whether it has complied with such requirements; (x) a written statement by the Company as to whether it qualifies as a registrant whose securities may be resold pursuant to short form registration statement; (y) a copy of the most recent annual or quarterly report of the Company; and (z) such other reports and documents as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to sell any Registrable Securities without registration.

(o) Other Registration Rights.

(i) The Company covenants that it will not grant any right of registration under the Securities Act (or any law or regulation of similar effect in force in the United States or elsewhere) relating to any of its Ordinary Shares or Ordinary Share Equivalents or other equity securities to any person unless each of the Holders (other than the Company Holders) shall be entitled to (x) notice of any such registration substantially similar to that notice provided in Section 2(c)(i) or Section 3(a)(i) hereof and (y) to have included in any registration effected pursuant to Sections 2 or 3 hereof all Registrable Securities requested by such Holders to be so included prior to the inclusion of any securities requested to be registered by the persons entitled to any such other registration rights pursuant to any right of registration comparable to those contained in Section 2 or Section 3 hereof. In any event, the Company covenants that it will not grant any new right of registration under the Securities Act (or any law or regulation of similar effect in force in the United States or elsewhere) relating to any of its Ordinary Shares or Ordinary Share Equivalents or other equity securities to any person comparable to the rights contained in Section 2 hereof without providing that the exercise of such new right during the eighteen month period following the completion of the Initial Public Offering will only be permitted following the consummation of any underwritten public offering by the Holders (other than the Company Holders).

(ii) The Company shall not at any time grant to any other holders of Ordinary Shares, Ordinary Share Equivalents or other equity securities of the Company any rights to request the Company to effect the registration (whether requested or incidental)

29

under the Securities Act or otherwise of any such securities on any terms more favorable to such holders than the terms set forth in this Agreement.

(iii) The Company covenants that it will not enter into, or cause or permit any of its Affiliates to enter into, any agreement which conflicts with or limits or prohibits the exercise of the rights granted to the Holders in this Agreement.

(iv) If the Company at any time proposes to effect a public offering in a jurisdiction other than the United States of any of its Ordinary Shares, Ordinary Share Equivalents or any other of its securities (other than a public offering (i) relating to Ordinary Shares issuable upon exercise of employee share options or in connection with any employee benefit or similar plan of the Company or its subsidiaries or (ii) in connection with an acquisition, directly or indirectly, by the Company of another company), the Company and the Holders will have the rights and be subject to the obligations agreed in this Agreement to the extent and where applicable.

(p) Third Party Beneficiaries. This Agreement is for the benefit of the parties hereto and their successors and permitted assigns and no third party shall have any right, title or interest in this Agreement as a third party beneficiary (express or implied) or otherwise, provided that (x) each Company Holder shall be a third party beneficiary of this Agreement, subject to all of the conditions and obligations in this Agreement applicable to such Company Holder and subject to the terms and conditions of Section 3(c) in the Management Shareholder's Agreement to which such Company Holder is a party, with the understanding that the parties to this Agreement shall be entitled to amend, modify, suspend, rescind or terminate, or waive any provision of, this Agreement without any notice to or consent of the Company Holders, provided that, if any such action adversely affects only the Company Holders or adversely affects the Company Holders in a disproportionate manner relative to the other Holders then such action shall not be taken without the prior written consent of the Company Holders holding a majority of the Registrable Securities then held by all Company Holders, and with the further understanding that the Company Holders' Representative shall be entitled to receive notices and other communications and take decisions and exercise approvals, consents and other rights under or in connection with this Agreement for and on behalf of the Company Holders in accordance with the power of attorney granted to the Company Holders' Representative under each Management Shareholder's Agreement, and (y) each Permitted Distributee that is entitled to any rights under this Agreement in accordance with Section 5 shall be a third party beneficiary of this Agreement, subject to all of the conditions and obligations in this Agreement applicable to such Permitted Distributee, with the understanding that the parties to this Agreement shall be entitled to amend, modify, suspend, rescind or terminate, or waive any provision of, this Agreement without any notice to or consent of any Permitted Distributees, provided that, if any such action adversely affects only such Permitted Distributees or adversely affects such Permitted Distributees in a disproportionate manner relative to the other Holders then such action shall not be taken without the prior written consent of such Permitted Distributees holding a majority of the Registrable Securities then held by all such Permitted Distributees.

(q) Effective Date; Termination.

(i) Sections 3(a)(iv), 4 and 9(l) of this Agreement shall become effective on and as of the date hereof and together with the Prior Agreement shall constitute the entire agreement and understanding of the parties hereto and thereto in respect of the subject matter contained herein and therein prior to the completion date of the Company's Initial Public Offering. The remainder of this Agreement shall become effective on the completion date (the "Effective Date") of the Initial Public Offering and prior to such time shall have no force

30

or effect. If the Initial Public Offering is abandoned or is not completed for any reason prior to June 30, 2004, this Agreement (other than Sections 3(a)(iv), 4 and 9(l) shall have no force or effect and no party shall have any liability or other obligation to any other party in respect of any of the terms or provisions hereof, provided that, for avoidance of doubt, the Prior Agreement, including Sections 3(a)(iv), 4 and 9(l) of this Agreement shall continue in full force and effect.

(ii) This Agreement shall terminate upon the first to occur (i) the written agreement among the Company (acting with the approval of its board of directors) and each Holder (other than the Company Holders, subject, however, to
Section 9(p) above) that this Agreement be terminated, (ii) a Change of Control (as defined in the Shareholders Agreement), except the registration rights of Holders under Section 3 (Incidental Registration) and all provisions in this Agreement attendant to such rights shall survive, (iii) the liquidation or dissolution of the Company and (iv) the tenth anniversary of the Effective Date, provided that, in any event, the terms of Section 7 and Sections 9(d), (e) and
(f) shall survive.

The remaining 184,055 Shares may be granted to new hires or as additional Awards, as and when determined in the sole discretion of the Committee. The Shares may consist, in whole or in part, of unissued Shares or previously issued Shares. The issuance of Shares or the payment of cash upon the exercise of an Award or in consideration of the cancellation or termination of an Award shall reduce the total number of Shares available under the Plan, as applicable. Shares that are subject to Awards (or portions thereof) that are forfeited, are cancelled, expire, terminate or lapse without the payment of consideration may be granted again under the Plan.

4. ADMINISTRATION

(a) The Plan shall be administered by the Committee, which may delegate its duties and powers in whole or in part to any subcommittee thereof consisting solely of at least two individuals who, during any period the Company is subject to Section 16 of the Act, are intended to qualify as "Non-Employee Directors" within the meaning of Rule 16b-3 under the


6

Act (or any successor rule thereto) and, to the extent required by Section 162(m) of the Code (or any successor section thereto), "outside directors" within the meaning thereof.

(b) The Committee shall have the full power and authority to make, and establish the terms and conditions of, any Award to any person eligible to be a Participant, consistent with the provisions of the Plan and to waive any such terms and conditions at any time (including, without limitation, accelerating or waiving any vesting conditions). Subject to Section 5(b), Awards may, in the discretion of the Committee, be made under the Plan in assumption of, or in substitution for, outstanding awards previously granted by the Company or its Affiliates or a company acquired by the Company or with which the Company combines. The number of Shares underlying such substitute awards shall be counted against the aggregate number of Shares available for Awards under the Plan.

(c) The Committee is authorized to interpret the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to make any other determinations that it deems necessary or desirable for the administration of the Plan, and may delegate such authority, as it deems appropriate. The Committee may correct any defect or supply any omission or reconcile any inconsistency in the Plan in the manner and to the extent the Committee deems necessary or desirable. Any decision of the Committee in the interpretation and administration of the Plan, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned (including, but not limited to, Participants and their beneficiaries or successors).

(d) The Committee shall require payment of any amount it may determine to be necessary to withhold for federal, state, local or other taxes as a result of the exercise, grant or vesting of an Award. Unless the Committee specifies otherwise, the Participant may elect to pay a portion or all of such withholding taxes by (a) delivery in Shares or
(b) having Shares withheld by the Company with a Fair Market Value equal to the minimum statutory withholding rate from any Shares that would have otherwise been received by the Participant.

5. LIMITATIONS

(a) No Award may be granted under the Plan after the tenth anniversary of the Effective Date, but Awards theretofore granted may extend beyond that date.

(b) Without the approval of the shareholders of the Company, the Company shall not adjust an Option or Share Appreciation Right or exchange an Option or Share Appreciation Right with another Option or Share Appreciation Right that would result in an Award with a lower Option


7

Price or exercise price (except for adjustments pursuant
to Section 10 of the Plan).

(c) Notwithstanding any provision of the Plan other than
Section 10, the number of Shares under the Plan that may be issued in connection with grants of ISOs shall not exceed 150,000 Shares.

6. TERMS AND CONDITIONS OF OPTIONS

Options granted under the Plan shall be, as determined by the Committee, nonqualified or incentive stock options for federal income tax purposes, as evidenced by the related Award agreements, and shall be subject to the foregoing and the following terms and conditions and to such other terms and conditions, not inconsistent therewith, as the Committee shall determine:

(a) Option Price. (i) Prior to the date of the Initial Public Offering, the Option Price per Share shall be determined by the Committee, and, in the case of ISOs, shall comply with the requirements set forth in Section 6(d) of the Plan, and (ii) after the date of the Initial Public Offering, the Option Price per Share shall be determined by the Committee, but shall not be less than 100% of the Fair Market Value of the Shares on the date an Option is granted.

(b) Exercisability. Options granted under the Plan shall be exercisable at such time and upon such terms and conditions as may be determined by the Committee, but in no event shall an Option be exercisable more than ten years after the date it is granted, except as may be provided pursuant to Section 15.

(c) Exercise of Options. Except as otherwise provided in the Plan or in an Award agreement, an Option may be exercised for all, or from time to time any part, of the Shares for which it is then exercisable. For purposes of this Section 6, the exercise date of an Option shall be the date a notice of exercise is received by the Company, together with payment (or to the extent permitted by applicable law, provision for payment) of the full purchase price in accordance with Section 6(c). The purchase price for the Shares as to which an Option is exercised shall be paid to the Company, as designated by the Committee, pursuant to one or more of the following methods: (i) in cash or its equivalent (e.g., by check); (ii) in Shares having a Fair Market Value equal to the aggregate Option Price for the Shares being purchased and satisfying such other requirements as may be imposed by the Committee; provided, that such Shares have been held by the Participant for no less than six months, which period may be waived by the Committee (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment applying generally accepted accounting principles); (iii) partly in cash and partly in such Shares; or (iv) if there is a public market for the Shares at such time, through the delivery of irrevocable instructions to a broker to sell Shares


8

obtained upon the exercise of the Option and to deliver promptly to the Company an amount out of the proceeds of such Sale equal to the aggregate Option Price for the Shares being purchased. No Participant shall have any rights to dividends or other rights of a shareholder with respect to Shares subject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares and, if applicable, has satisfied any other conditions imposed by the Committee pursuant to the Plan.

(d) ISOs. The Committee may grant Options under the Plan to Participants who are employees of the Company that are intended to be ISOs. Such ISOs shall comply with the requirements of Section 422 of the Code (or any successor section thereto), including without limitation that the Option Price shall not be less than 100% of the Fair Market Value of the Shares on the date the ISO is granted. No ISO may be granted to any Participant who at the time of such grant, owns more than ten percent of the total combined voting power of all classes of shares of the Company or of any Subsidiary, unless (i) the Option Price for such ISO is at least 110% of the Fair Market Value of a Share on the date the ISO is granted and (ii) the date on which such ISO terminates is a date not later than the day preceding the fifth anniversary of the date on which the ISO is granted. Any Participant who disposes of Shares acquired upon the exercise of an ISO either (i) within two years after the date of grant of such ISO or (ii) within one year after the transfer of such Shares to the Participant, shall notify the Company of such disposition and of the amount realized upon such disposition. All Options granted under the Plan are intended to be nonqualified share options, unless the applicable Award agreement expressly states that the Option is intended to be an ISO. If an Option is intended to be an ISO, and if for any reason such Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a nonqualified share option granted under the Plan; provided that such Option (or portion thereof) otherwise complies with the Plan's requirements relating to nonqualified share options. In no event shall any member of the Committee, the Company or any of its Affiliates (or their respective employees, officers or directors) have any liability to any Participant (or any other Person) due to the failure of an Option to qualify for any reason as an ISO.

(e) Attestation. Wherever in this Plan or any agreement evidencing an Award a Participant is permitted to pay the exercise price of an Option or taxes relating to the exercise of an Option by delivering Shares, the Participant may, subject to procedures satisfactory to the Committee, satisfy such delivery requirement by presenting proof of beneficial ownership of such Shares, in which case the Company shall treat the Option as exercised without further payment and/or shall withhold such number of Shares from the Shares acquired by the exercise of the Option, as appropriate.


9

7. TERMS AND CONDITIONS OF SHARE APPRECIATION RIGHTS

(a) Grants. The Committee may grant (i) a Share Appreciation Right independent of an Option or (ii) a Share Appreciation Right in connection with an Option, or a portion thereof. A Share Appreciation Right granted pursuant to clause (ii) of the preceding sentence (A) may be granted at the time the related Option is granted or at any time prior to the exercise or cancellation of the related Option, (B) shall cover the same number of Shares covered by an Option (or such lesser number of Shares as the Committee may determine) and (C) shall be subject to the same terms and conditions as such Option except for such additional limitations as are contemplated by this
Section 7 (or such additional limitations as may be included in an Award agreement).

(b) Terms. The exercise price per Share of a Share Appreciation Right shall be an amount determined by the Committee but in no event shall such amount be less than the Fair Market Value of a Share on the date the Share Appreciation Right is granted, except that, notwithstanding the foregoing, in the case of a Share Appreciation Right granted in conjunction with an Option, or a portion thereof, the exercise price may not be less than the Option Price of the related Option. Each Share Appreciation Right granted independent of an Option shall entitle a Participant upon exercise to an amount equal to
(i) the excess of (A) the Fair Market Value on the exercise date of one Share over (B) the exercise price per Share, times (ii) the number of Shares covered by the Share Appreciation Right. Each Share Appreciation Right granted in conjunction with an Option, or a portion thereof, shall entitle a Participant to surrender to the Company the unexercised Option, or any portion thereof, and to receive from the Company in exchange therefor an amount equal to (i) the excess of (A) the Fair Market Value on the exercise date of one Share over (B) the Option Price per Share, times (ii) the number of Shares covered by the Option, or portion thereof, which is surrendered. Payment shall be made in Shares or in cash, or partly in Shares and partly in cash (any such Shares valued at such Fair Market Value), all as shall be determined by the Committee. Share Appreciation Rights may be exercised from time to time upon actual receipt by the Company of written notice of exercise stating the number of Shares with respect to which the Share Appreciation Right is being exercised. The date a notice of exercised is received by the Company shall be the exercise date. No fractional Shares will be issued in payment for Share Appreciation Rights, but instead cash will be paid for a fraction or, if the Committee should so determine, the number of Shares will be rounded downward to the next whole Share.

(c) Limitations. The Committee may impose, in its discretion, such conditions upon the exercisability or transferability of Share Appreciation Rights as it may deem fit.

8. RESTRICTED SHARES

(a) Grant. Subject to the provisions of the Plan, the Committee shall determine the number of Restricted Shares to be granted to each Participant, the duration of the period during which, and the conditions, if any, under which, the Restricted Shares may be forfeited to the Company, and the other terms and conditions of such Awards.

(b) Transfer Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered, except as provided in the Plan or the applicable Award agreement. Certificates issued in respect of Restricted Shares shall be registered in the name of the Participant and deposited by such Participant, together with a stock power endorsed in blank, with the Company. After the lapse of the restrictions applicable to such Restricted Shares, the Company shall deliver such certificates to the Participant or the Participant's legal representative.

(c) Dividends. Dividends paid on any Restricted Shares may be paid directly to the Participant, withheld by the Company subject to vesting of the Restricted Shares pursuant to the terms of the applicable Award agreement, or may be reinvested in additional Restricted Shares, as determined by the Committee in its sole discretion.

9. OTHER SHARE-BASED AWARDS

(a) Generally. The Committee, in its sole discretion, may grant or sell Awards of Shares and Awards that are valued in whole or in part by reference to, or are otherwise based on the Fair Market Value of, Shares ("Other Share-Based Awards"). Such Other Share-Based Awards shall be in such form, and dependent on such conditions, as the Committee shall determine, including, without limitation, the right to receive, or vest with respect to, one or more Shares (or the equivalent cash value of such Shares) upon the completion of a specified period of service, the occurrence of an event and/or the attainment of performance objectives. Other Share-Based Awards may be granted alone or in addition to any other Awards granted under the Plan. Subject to the provisions of the Plan, the Committee shall determine the number of Shares to be awarded under (or otherwise related to) such Other Share-Based Awards; whether such Other Share-Based Awards shall be settled in cash, Shares or a combination of cash and Shares; and all other terms and conditions of such Awards (including, without limitation, the vesting provisions thereof and provisions ensuring that all Shares so awarded and issued shall be fully paid and non-assessable).

10. ADJUSTMENTS UPON CERTAIN EVENTS

Notwithstanding any other provisions in the Plan to the contrary, the following provisions shall apply to all Awards granted under the Plan:


11

(a) Generally. In the event of any change in the outstanding Shares after the Effective Date by reason of any Share dividend or split, reorganization, recapitalization, merger, consolidation, spin-off, combination, combination or transaction or exchange of Shares or other corporate exchange, or any distribution to shareholders of Shares other than regular cash dividends or any transaction similar to the foregoing, the Committee in its sole discretion and without liability to any person shall make such substitutions or adjustments as it deems to be equitable, in its sole discretion, and necessary to preserve the benefits or potential benefits intended to be made available under this Plan as to (i) the number or kind of Shares or other securities issued or reserved for issuance pursuant to the Plan or pursuant to outstanding Awards, (ii) the maximum number of Shares for which Awards (including limits established for Restricted Shares or Performance-Based Awards) may be granted during a calendar year to any Participant, (iii) the Option Price or exercise price of any Share Appreciation Right, and/or
(iv) any other affected terms of such Awards.

(b) Change in Control.

(i) In the event of a Change in Control after the Effective Date, solely with respect to the Initial Grant, without any action required, with respect to Awards outstanding as of the date of such Change in Control (x) all Options and Share Appreciation Rights shall become fully and immediately exercisable and vested to the full extent of the original grant, (y) the restrictions applicable to any Restricted Shares shall lapse, and such Restricted Shares shall become fully and immediately vested, and (z) the restrictions and other conditions applicable to any Other Share-Based Award shall lapse, and such Other Share-Based Award shall become free of all restrictions, limitations and conditions or, if applicable, shall be considered earned and payable in full and immediately settled or distributed.

(ii) In the event of a Change in Control after the Effective Date, the Committee may, but shall not be obligated to, (A) with respect to any Award other than the Initial Grant, accelerate, vest or cause the restrictions to lapse with respect to, all or any portion of an Award or (B) cancel Awards for fair value (as reasonably determined in the discretion of the Committee) which, in the case of Options and Share Appreciation Rights, may equal, but in any event shall not be less than, the excess, if any, of value of the consideration to be paid in the Change in Control transaction to holders of the same number of Shares subject to such Options or Share Appreciation Rights (or, if no consideration is paid in any such transaction, the Fair Market Value of the Shares subject to such Options or Share Appreciation Rights) over the aggregate exercise price of such Options or Share Appreciation Rights or (C) provide for the issuance of substitute Awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted hereunder as determined


12

by the Committee in its sole discretion or (D) provide that for a period of at least 15 days prior to the Change in Control, such Options shall be exercisable as to all Shares subject thereto and that upon the occurrence of the Change in Control, such Options shall terminate and be of no further force and effect.

11. NO RIGHT TO EMPLOYMENT OR AWARDS

The granting of an Award under the Plan shall impose no obligation on the Company or any Affiliate to continue the Employment of a Participant and shall not lessen or affect the Company's or Affiliate's right to terminate the Employment of such Participant. No Participant or other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Participants, or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee's determinations and interpretations with respect thereto need not be the same with respect to each Participant (whether or not such Participants are similarly situated).

12. SUCCESSORS AND ASSIGNS

The Plan shall be binding on all successors and assigns of the Company and a Participant, including without limitation, the estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant's creditors.

13. NONTRANSFERABILITY OF AWARDS

Unless otherwise determined by the Committee, an Award shall not be transferable or assignable by the Participant otherwise than by will or by the laws of descent and distribution. An Award exercisable after the death of a Participant may be exercised by the legatees, personal representatives or distributees of the Participant.

14. AMENDMENTS OR TERMINATION

The Board or the Committee may amend, alter or discontinue the Plan, but no amendment, alteration or discontinuation shall be made, (a) without the approval of the shareholders of the Company, if such action would (except as is provided in Section 10 of the Plan), increase the total number of Shares reserved for the purposes of the Plan, (b) without the consent of a Participant, if such action would diminish any of the rights of the Participant under any Award theretofore granted to such Participant under the Plan or (c) without the approval of the shareholders of the Company, to Section 5(b), relating to repricing of Options or Share Appreciation Rights, to permit such repricing; provided, however, that the Committee may amend the Plan in such manner as it deems necessary to permit the granting of Awards meeting the requirements of the Code or other applicable laws.

15. CONFLICTS OF LAW; INTERNATIONAL PARTICIPANTS

The Committee may, in its sole discretion, amend the terms of the Plan or Awards in order (i) to comply with United States Federal law or the rules of any securities exchange in


13

the United States or (ii) with respect to Participants who reside or work outside the United States of America, to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for a Participant, the Company or an Affiliate, and the Committee may, where appropriate, establish one or more sub-plans to reflect such amended or varied provisions.

16. OTHER BENEFIT PLANS

All Awards shall constitute a special incentive payment to the Participant and shall not be taken into account in computing the amount of salary or compensation of the Participant for the purpose of determining any benefits under any pension, retirement, profit-sharing, bonus, life insurance or other benefit plan of the Company or under any agreement between the Company and the Participant, unless such plan or agreement specifically provides otherwise.

17. CHOICE OF LAW

The Plan shall be governed by and construed in accordance with the laws of Bermuda, without regard to conflicts of laws principles.

18. ARBITRATION

In the event of any controversy between a Participant and the Company arising out of, or relating to, this Plan or an Award granted hereunder which cannot be settled amicably by the parties, such controversy shall be finally, exclusively and conclusively settled by mandatory arbitration conducted expeditiously in accordance with the American Arbitration Association rules, by a single independent arbitrator. If the parties are unable to agree on the selection of an arbitrator, then either the Participant or the Company may petition the American Arbitration Association for the appointment of the arbitrator, which appointment shall be made within ten (10) days of the petition therefor. Either party to the dispute may institute such arbitration proceeding by giving written notice to the other party. A hearing shall be held by the arbitrator in New York, London or Bermuda as agreed by the parties (or, failing such agreement, in Bermuda) within thirty (30) days of his or her appointment. The decision of the arbitrator shall be final and binding upon the parties and shall be rendered pursuant to a written decision that contains a detailed recital of the arbitrator's reasoning. Judgment upon the award rendered may be entered in any court having jurisdiction thereof.

19. EFFECTIVENESS OF THE PLAN

The Plan shall be effective as of the Effective Date, subject to the approval of the shareholders of the Company.

(a) Each Borrower agrees to pay its pro rata share (calculated, for any day, based on the percentage which the principal amount of the Loans outstanding to such Borrower at the close of business on such day constitutes of the then aggregate principal amount of the Loans to all Borrowers (in the case of each Borrower, its "Proportionate Share")), provided, that at any time when no Loans are outstanding, the pro rata share of the Company shall be deemed to be 100%) to the Administrative Agent for the account of each Lender which has a then effective Commitment or a then outstanding Loan a facility fee (a "Facility Fee") for the period from and including the date hereof to the last day upon which such Lender's Commitment shall have terminated and such Lender's Loans shall have been paid in full, computed at the Facility Fee Rate on the average daily amount of the Commitment of such Lender (whether or not utilized) during the period (the "Computation Period") for which payment is made (or, if any Lender continues to have any Loans after its Commitment terminates, on the average daily amount of such Lender's Loans from and including the date on which its Commitment terminates to but excluding the date on which such Lender ceases to have any Loans outstanding), payable quarterly in arrears on each Fee Payment Date, commencing on the first such date to occur after the date hereof.

(b) The Borrowers agree to pay to the Administrative Agent for the account of each Lender, in arrears on each Fee Payment Date, a utilization fee (a "Utilization Fee") based upon the average daily amount of the outstanding Loans of such Lender at a rate per annum equal to the Utilization Fee Rate when and for as long as the aggregate outstanding principal amount of the sum of (a) the Loans hereunder plus (b) the aggregate principal amount of the Loans (as defined therein) under the Other Credit Agreement exceeds 60% of the sum of (x) the aggregate Commitments hereunder and (y) the aggregate amount of the Commitments (as defined therein) under the Other Credit Agreement. Payments made by the Borrowers hereunder shall be made in accordance with each Borrower's Proportionate Share

(c) The Company agrees to pay to the Administrative Agent the fees in the amounts and on the dates as set forth in any fee agreements with the Administrative Agent and to perform any other obligations contained therein.

2.4 Termination or Reduction of Commitments. The Company shall have the right, upon not less than five Business Days' notice to the Administrative Agent, to terminate the Commitments or, from time to time, to reduce the amount of the Commitments; provided that no such termination or reduction of Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof, the Total Loans would exceed the Total Commitments. Any such reduction shall be in an amount equal to $5,000,000, or a whole multiple thereof, and shall reduce permanently the Commitments then in effect.


16

2.5 Optional Prepayments. Each Borrower may at any time and from time to time prepay the Loans made by the Lenders to such Borrower, in whole or in part, without premium or penalty, upon irrevocable notice delivered by the Company to the Administrative Agent no later than 2:00 P.M., London time, three Business Days prior thereto, in the case of Eurodollar Loans, and no later than 2:00 P.M., London time, one Business Day prior thereto, in the case of ABR Loans, which notice shall specify the date and amount of prepayment and whether the prepayment is of Eurodollar Loans or ABR Loans; provided, that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, such Borrower shall also pay any amounts owing pursuant to Section 2.14. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Loans that are ABR Loans) accrued interest to such date on the amount prepaid. Partial prepayments of ABR Loans and Eurodollar Loans for all Borrowers shall be in an aggregate principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof.

2.6 Conversion and Continuation Options. (a) The Company may elect from time to time to convert Eurodollar Loans to ABR Loans by giving the Administrative Agent prior irrevocable notice of such election substantially in the form of Exhibit I no later than 2:00 P.M., London time, on the proposed conversion date, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Company may elect from time to time to convert ABR Loans to Eurodollar Loans by giving the Administrative Agent prior irrevocable notice of such election no later than 2:00 P.M., London time, on the third Business Day preceding the proposed conversion date (which notice shall specify the length of the initial Interest Period therefor), provided that no ABR Loan may be converted into a Eurodollar Loan when any Event of Default or Default has occurred and is continuing and the Administrative Agent or the Required Lenders have determined in its or their sole discretion not to permit such conversions. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Company giving irrevocable notice to the Administrative Agent, substantially in the form of Exhibit I hereto in accordance with the applicable provisions of the term "Interest Period" set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans, provided that no Eurodollar Loan may be continued as such when any Event of Default or Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Company shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to ABR Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

2.7 Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than ten Eurodollar Tranches shall be outstanding at any one time.

2.8 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin.


17

(b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin.

(c) (i) So long as any Event of Default shall have occurred and be continuing, the principal amount of all Loans shall bear interest at a rate per annum equal to the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% and (ii) if all or a portion of any interest payable on any Loan or any Facility Fee or Utilization Fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to ABR Loans plus 2%, in each case as described in this clause (ii), from the date of such non-payment until such amount is paid in full (as well after as before judgment).

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this
Section shall be payable from time to time on demand.

2.9 Computation of Interest and Fees. (a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to ABR Loans the rate of interest on which is calculated on the basis of the Federal Funds Effective Rate, the interest thereon shall be calculated on the basis of a 365- (or 366, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Company and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Company and the relevant Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on each Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall deliver to the Company a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.8(a).

2.10 Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon each Borrower absent manifest error) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Company and the relevant Lenders as soon as practicable thereafter. Upon receipt of such notice, the Borrower may revoke any notice of borrowing, conversion or continuation then submitted by it. If the Borrower does not revoke such notice, then (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar


18

Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Company have the right to convert Loans to Eurodollar Loans.

2.11 Pro Rata Treatment and Payments. (a) Each borrowing by any Borrower from the Lenders hereunder and any reduction of the Commitments of the Lenders shall be made pro rata according to the Lenders' respective Commitments, and each payment by any Borrower on account of any Facility Fee or Utilization Fee shall be made pro rata to each Lender according to the respective amounts thereof owing pursuant to Section 2.3(a) or Section 2.3(b), as the case may be.

(b) Each payment (including each prepayment) by any Borrower on account of principal of and interest on the Loans made to it shall be made pro rata according to the respective outstanding principal amounts of such Loans then held by the Lenders.

(c) All payments (including prepayments) to be made by any Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 5:00 P.M., London time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(d) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon, at a rate equal to the greater of (i) the Federal Funds Effective Rate and (ii) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender's share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans, on demand, from the Borrowers.

(e) Unless the Administrative Agent shall have been notified in writing by the Company prior to the date of any payment due to be made by any Borrower hereunder that such Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that such Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by such Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on


19

demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against such Borrower.

2.12 Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.13 and changes in the rate of tax on the overall net income of such Lender);

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

(iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost (excluding taxes) to such Lender, by an amount that such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower to which such Loans were made shall pay such Lender any additional amounts necessary to compensate such Lender for such increased cost (excluding taxes) or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Company (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of its obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Company (with a copy to the Administrative Agent) of a written request therefor, the Company shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Company (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The Borrower shall pay such Lender the amount shown as due on such certificate within 10 Business Days after receipt by the Borrower. Notwithstanding anything to the contrary in this Section, the Company shall not be required to compensate a Lender pursuant to this Section for any amounts incurred more than six months prior to the date that such Lender notifies the


20

Company of such Lender's intention to claim compensation therefor; provided that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect. The obligations of the Company pursuant to this
Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.13 Taxes. (a) All payments made by (or on behalf of) any Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding Excluded Taxes. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") or Other Taxes are required to be deducted or withheld from any amounts payable to the Administrative Agent or any Lender hereunder,
(i) the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, (ii) the Borrower shall deduct or withhold such amounts and
(iii) the Borrower shall pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law; provided, however, that no Borrower shall be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes that are attributable to such Lender's failure to comply with the requirements of paragraph (e) of this Section.

(b) In addition, each Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Each Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Non-Excluded Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of such Borrower hereunder (including Non-Excluded Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.13) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Non-Excluded Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to such Borrower by a Lender or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) Whenever any Non-Excluded Taxes or Other Taxes are payable by a Borrower, as promptly as possible thereafter such Borrower shall send to the Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by such Borrower showing payment thereof.

(e) A Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender's judgment such completion, execution or submission would not materially prejudice the legal position of such Lender. To the extent the Borrower is a "U.S. Person" as defined in Section 7701(a)(30) of the Code (a "U.S. Borrower"), each Lender (or Transferee) that is not a U.S. Person (a "Non-U.S. Lender") shall deliver to


21

the U.S. Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN, Form W-8ECI or, in the case of a Transferee, a Form W-81MY, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of "portfolio interest", a statement substantially in the form of Exhibit F and a Form W-8BEN or, in the case of a Transferee, a Form W-8IMY, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the U.S. Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender within 10 Business Days of the request by the U.S. Borrower. Each Non-U.S. Lender shall promptly notify the U.S. Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the U.S. Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). If any Non-U.S. Lender provides a Form W-8IMY, such Non-U.S. Lender must also attach the additional documentation that must be transmitted with the Form W-8IMY, including the appropriate forms described in this Section 2.13(e).

(f) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.14 Indemnity. Each Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) default by such Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Company has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by such Borrower in making any prepayment of or conversion from Eurodollar Loans after the Company has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.15 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.12 or 2.13(a) with respect to such Lender, it will, if requested by the Company, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event or assign its rights and obligations hereunder to an Affiliate with the object of avoiding the consequences of such event; provided, that such designation or assignment is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) or such Affiliate, as the case may be, to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of any Borrower or the rights of any Lender pursuant to Section 2.12 or 2.13(a).

2.16 Replacement of Lenders. The Company shall be permitted to replace any Lender


22

that (a) requests reimbursement for amounts owing pursuant to Section 2.12 or 2.13(a) or (b) defaults in its obligation to make Loans hereunder, with a replacement financial institution; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default or Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement, such Lender shall, within 30 days of the Company's request have taken no action under Section 2.15 that eliminates the continued need for payment of amounts owing pursuant to Section 2.12 or 2.13(a), (iv) the replacement financial institution shall purchase, at par, all Loans and other amounts (including accrued interest) owing to such replaced Lender on or prior to the date of replacement, (v) the Borrowers shall be liable to such replaced Lender under Section 2.14 if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto as if it were prepaid on the date of such purchase, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 9.6 (provided that each Borrower shall be obligated to pay the portion of the registration and processing fee referred to therein based on such Borrower's Proportionate Share), (viii) until such time as such replacement shall be consummated, the Borrowers shall pay all additional amounts (if any) required pursuant to Section 2.12 or 2.13(a), as the case may be, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

SECTION 3. REPRESENTATIONS AND WARRANTIES

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Loans, the Company hereby represents and warrants to the Administrative Agent and each Lender that:

3.1 Financial Condition. The audited consolidated balance sheet of the Company and its Subsidiaries as at December 31, 2002, and the related consolidated statement of comprehensive income and of cash flows for the fiscal year ended on such date, reported on by and accompanied by an unqualified report from KPMG Audit Plc, present fairly the consolidated financial condition of the Company and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The unaudited consolidated balance sheet of the Company and its Subsidiaries as at March 31, 2003, and the related unaudited consolidated statements of comprehensive income and cash flows for the three-month period ended on such date, present fairly the consolidated financial condition of the Company and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the three-month period then ended (subject to normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). No Group Member has any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or unusual forward or long-term commitments, including any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the period from December 31, 2002 to and including the date of this Agreement there has been no Disposition by any Group Member of any material part of its business or property.

3.2 No Change. Since December 31, 2002, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

3.3 Existence; Compliance with Law. Each Group Member (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the power and authority, and the legal right, to own and operate its property, to lease the property it operates as lessee

Neither the Company nor any Subsidiary is subject to any Private Act.

3.4 Power; Authorization; Enforceable Obligations. (a) Subject to obtaining any consent set forth in Part II of Schedule 3.4 (unless an Applicable Amendment shall have become effective) prior to a Consent Event, each Loan Party has or will have the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of each Borrower, to obtain Loans hereunder, and each Loan Party has or will have taken all necessary organizational action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of each Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the Loans hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, except (A)(x) consents, authorizations, filings and notices described in Part I of Schedule 3.4, which consents, authorizations, filings and notices have been obtained or, except as noted therein, made and are in full force and effect and (y) the consents described in Part II of Schedule 3.4 (unless an Applicable Amendment shall have become effective) which consents (or amendment or amendments, as the case may be) will be obtained prior to a Consent Event, (B) consents of any applicable Governmental Authority (including, where applicable, the Bermuda Monetary Authority, the U.K. Financial Services Authority and any relevant insurance commission or analogous Governmental Authority in the United States) required in the event of the exercise by the Collateral Agent of any right (1) to control or to allow any assignee of the Collateral Agent to control any Insurance Subsidiary or (2) to sell or transfer in accordance with the terms and conditions of any Security Document any Capital Stock of any Insurance Subsidiary pledged in accordance with the terms of such Security Document (including, in such case, any consent required for the purchaser or the transferee of such Capital Stock) and (C) any consent or authorization of, filing with or notice to, the relevant insurance commission or other Governmental Authority pursuant to any applicable Requirement of Law in connection with the creation subsequent to the Closing Date in accordance with
Section 5.4 of a security interest in the Capital Stock of any Material Subsidiary which is an Insurance Subsidiary. Each Loan Document has been duly executed and delivered on behalf of each Loan Party which is a party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party which is a party thereto, enforceable against each Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

(b) Under the laws of Bermuda in force at the date hereof, none of the Borrowers nor any Subsidiary Guarantor will be required to make any deduction or withholding from any payment it may make hereunder or under the Notes.

(c) Under the laws of Bermuda, the claims of the Collateral Agent and the Lenders against each Borrower and each Subsidiary Guarantor under this Agreement and the Notes will rank at least pari passu with the claims of all its other unsecured creditors, except creditors whose claims are preferred solely by any bankruptcy, insolvency or other similar law of general application governing the enforcement of creditors' rights.


24

(d) In any proceedings taken in Bermuda in relation to this Agreement, the choice of New York law as the governing law of this Agreement, and any judgment obtained in the United States, will be recognized and enforced.

3.5 No Legal Bar. Subject to obtaining any consents which may be required pursuant to Part II of Schedule 3.4 (unless an Applicable Amendment shall have become effective), the execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law (assuming compliance with any Requirement of Law relating to the consent of any Governmental Authority required in the event of the exercise by the Collateral Agent or any assignee of the Collateral Agent of any right to control any Insurance Subsidiary or to sell or transfer any Capital Stock of any Insurance Subsidiary in accordance with the terms and conditions of any Security Document (including, in such case, any consent required for the purchaser or the transferee of such Capital Stock)) or any Contractual Obligation of any Group Member and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents and except, in the case of Contractual Obligations, to the extent that the failure of any of the statements in this
Section 3.5 to be accurate could not reasonably be expected to have a Material Adverse Effect).

3.6 Litigation. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending, or, to the knowledge of any Borrower, threatened, by or against any Group Member or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

3.8 Ownership of Property; Liens. Each Group Member has good title to, or a valid leasehold interest in all its real and personal property material to its business except for minor defects in title that could not reasonably be expected to have a Material Adverse Effect, and none of such property is subject to any Lien not permitted by Section 6.6.

3.9 Taxes. Each Group Member has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the relevant Group Member except to the extent that failure to do so could not reasonably be expected to have a Material Adverse Effect); no tax Lien has been filed, and, to the knowledge of any Borrower, no claim is being asserted, with respect to any such tax, fee or other charge.

None of the Borrowers nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and none of the Borrowers nor any Commonly Controlled Entity would become subject to any material liability under ERISA if such Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

3.12 Investment Company Act. No Loan Party is an "investment company", or a company "controlled" by an "investment company", within the meaning of the Investment Company Act of 1940, as amended.

Law; and

(e) Hazardous Materials have not been transported or disposed of by any Group Member in a manner or to a location that could reasonably be expected to give rise to liability under any Environmental Law.

3.16 Accuracy of Information, etc. To the best of the Company's knowledge, the Confidential Information Memorandum, taken as a whole, is correct in all material respects as of the date thereof and does not, as of the date thereof, contain any untrue statement of a material fact or omit any material fact necessary to make the statements therein (taken as a whole) not misleading as of such date in light of the circumstances under which they made; provided, however, that this representation does not extend to (i) financial projections and other forward looking statements contained in the Confidential Information Memorandum (the "Projections") and (ii) information in the Confidential Information Memorandum which is referenced to a specific source or derived from public or other sources. The Projections contained in the Confidential Information Memorandum have been prepared in good faith based upon assumptions reasonably believed by the Company to be reasonable, it being understood, and the Administrative Agent and each Lender understands that the Projections are subject to significant uncertainties and contingencies many of which are beyond the control of the Company and there can be no assurances that such Projections will be realized.

No written statement or information delivered by any Loan Party to the Administrative Agent, the Collateral Agent or the Lenders contained in this Agreement or any other Loan Document, taken as a whole, contains any untrue statement of a material fact or omits any material fact necessary to make the statements therein (taken as a whole) not misleading as of the date of such statement or information in light of the circumstances under which they were provided.

3.17 Security Documents. The Guarantee and Collateral Agreement is effective to create in favor of the Collateral Agent, for the benefit of the Lenders, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof subject to (i) the consent of any applicable Governmental Authority required by any applicable Requirement of Law in the event of the exercise by the Collateral Agent of any right (A) to control or to allow any assignee of the Collateral Agent to control any Insurance Subsidiary or (B) to sell or transfer any Capital Stock (including, in such case, any consent required for the purchaser or the transferee of such Capital Stock). In the case of the Pledged Stock described in the Guarantee and Collateral Agreement, when stock certificates representing such Pledged Stock are delivered to the Collateral Agent and Uniform Commercial Code financing statements are filed in the applicable filing offices, the Guarantee and Collateral Agreement shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties organized under the laws of the United States in such Collateral and the proceeds thereof, as security for the Obligations (as defined in the Guarantee and Collateral Agreement), in each case prior and superior in right to any other Person. A priority interest in the Collateral of any Material Subsidiary organized under the laws of Bermuda will be created in Bermuda upon the registration of a charge with the Registrar of Companies. The UK Charge Over Shares is effective to create in favor of the Collateral Agent, for the benefit of the Lenders, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case of the Pledged Stock described in the UK Charge Over Shares, the UK Charge Over Shares shall constitute a fully perfected Lien on, and security interest in, such Pledged Stock of the Material Subsidiary organized under the laws of the United Kingdom when stock certificates representing such Pledged Stock are delivered to the Collateral Agent and upon any applicable registration of the share charges at the Companies House.

SECTION 8. THE AGENTS

8.1 Appointment. Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents and the Collateral Agent as the agent of such Lender, the Administrative Agent, the Other Administrative Agent and the Other Lenders under the Security Documents, and each such Lender irrevocably authorizes the Administrative Agent and the Collateral Agent, as the case may be, in such capacities, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents, as applicable, and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent and the Collateral Agent, as the case may be, by the terms of this Agreement and the other Loan Documents, as applicable (and, in the case of the Collateral Agent, the Other Credit Agreement and the Security Documents), together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, neither the Administrative Agent nor the Collateral Agent shall have any duties or responsibilities, except those expressly set forth herein (and, in the case of the Collateral Agent, in the Other Credit Agreement), or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent or the Collateral Agent.

The Administrative Agent and each Lender understand and agree that all Liens created by the Security Documents on the Collateral have been created in favor of the Collateral Agent, for the benefit of the Administrative Agent, the Other Administrative Agent, the Lenders and the Other Lenders, that all rights to take remedial action with respect to the Collateral under the Security Documents have been granted to the Collateral Agent and that neither the Administrative Agent, the Other Administrative Agent, any Lender nor any Other Lender has the right to take any such remedial action with respect to the Collateral other than through the Collateral Agent.

8.2 Delegation of Duties. The Administrative Agent and the Collateral Agent may each execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. Neither the Administrative Agent nor the Collateral Agent shall be responsible for the negligence or misconduct of any agents or attorneys in-fact selected by it with reasonable care.

8.3 Exculpatory Provisions. Neither any Agent nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing have resulted from its or such Person's own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any


40

recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party a party thereto to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party.

8.4 Reliance. (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrowers), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

(b) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrowers), independent accountants and other experts selected by the Collateral Agent. The Collateral Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Collateral Agent shall be fully justified in failing or refusing to take any action under any Security Document unless it shall first receive the direction of the Administrative Agent under Section 7 of this Agreement and the Other Administrative Agent under Section 7 of the Other Credit Agreement, as applicable, or such advice or concurrence of (x) the Required Lenders (or, if so specified by this Agreement, all Lenders) and (y) the Required Lenders (as defined in the Other Credit Agreement) (or, if so specified by the Other Credit Agreement, all Other Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders and the Other Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under the Security Documents at the direction of the Administrative Agent under Section 7 of this Agreement and the Other Administrative Agent under Section 7 of the Other Credit Agreement, as applicable, or in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders) and the Required Lenders (as defined in the Other Credit Agreement) (or, if so specified by the Other Credit Agreement, all Other Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.


41

8.5 Notice of Default. (a) The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless it has received notice from a Lender or the Company referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

(b) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless it has received notice from the Administrative Agent, a Lender or the Company referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". The Collateral Agent shall take action with respect to such Default or Event of Default as shall be reasonably directed by the Administrative Agent under Section 7 of this Agreement and the Other Administrative Agent under Section 7 of the Other Credit Agreement, as applicable, or by (x) the Required Lenders (or, if so specified by this Agreement, all Lenders) and (y) the Required Lenders (as defined in the Other Credit Agreement) (or, if so specified by the Other Credit Agreement, all Other Lenders); provided that unless and until the Collateral Agent shall have received such directions, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders and the Other Lenders.

8.6 Non-Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that neither the Agents nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, neither the Administrative Agent nor the Collateral Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan Party or any affiliate of a Loan Party that may come into the possession of the Administrative Agent or the Collateral Agent or any of its respective officers, directors, employees, agents, attorneys-in-fact or affiliates.

8.7 Indemnification. (a) The Lenders agree to indemnify each Agent (other than the Collateral Agent) in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation of each Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if


42

indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent's gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

(b) The Lenders agree to indemnify the Collateral Agent in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation of each Borrower to do so), ratably according to the respective percentages which (i) the Aggregate Exposure of each Lender constitutes of (ii) the sum of (x) the Aggregate Exposure of all Lenders and (y) the Other Aggregate Exposure of all Other Lenders in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments and/or Other Commitments shall have terminated and the Loans and/or Other Loans shall have been paid in full, ratably in accordance with such percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Collateral Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Collateral Agent's gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

8.8 Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Loans made or renewed by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms "Lender" and "Lenders" shall include each Agent in its individual capacity.

8.9 Successor Administrative Agent and Collateral Agent. (a) The Administrative Agent may resign as Administrative Agent upon 30 days' notice to the Lenders and the Company. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 7(a) or Section 7(g) with respect to any Borrower shall have occurred and be continuing) be subject to approval by the Company (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent and the term "Administrative Agent" shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent's rights, powers and duties as Administrative Agent shall be terminated, without


43

any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 30 days following a retiring Administrative Agent's notice of resignation, the retiring Administrative Agent's resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders under this Agreement appoint a successor agent as provided for above. After any retiring Administrative Agent's resignation as Administrative Agent, the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

(b) The Collateral Agent may resign as Collateral Agent upon 30 days' notice to the Lenders, the Other Lenders and the Company. If the Collateral Agent shall resign as Collateral Agent under this Agreement, then (x) the Required Lenders under this Agreement and (y) the Required Lenders (as defined therein) under the Other Credit Agreement shall appoint from among the Lenders a successor collateral agent, which successor collateral agent shall (unless an Event of Default under Section 7(a) or Section 7(g) with respect to any Borrower shall have occurred and be continuing) be subject to approval by the Company (which approval shall not be unreasonably withheld or delayed), whereupon such successor collateral agent shall succeed to the rights, powers and duties of the Collateral Agent and the term "Collateral Agent" shall mean such successor collateral agent effective upon such appointment and approval, and the former Collateral Agent's rights, powers and duties as Collateral Agent shall be terminated, without any other or further act or deed on the part of such former Collateral Agent or any of the parties to this Agreement or any holders of the Loans. If no successor collateral agent has accepted appointment as Collateral Agent by the date that is 30 days following a retiring Collateral Agent's notice of resignation, the retiring Collateral Agent's resignation shall nevertheless thereupon become effective, and the retiring Collateral Agent (after consultation with the Company) may appoint a financial institution rated at least `A' by S&P or `A' by Moody's, as a successor collateral agent. After any retiring Collateral Agent's resignation as Collateral Agent the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent under this Agreement and the other Loan Documents.

8.10 Documentation Agent. The Documentation Agent shall not have any duties or responsibilities hereunder in its capacity as such.

Neither this Agreement, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 9.1. The Required Lenders and each Loan Party which is a party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Administrative Agent or, as the case may be, the Collateral Agent, and each Loan Party which is a party to the relevant Loan Document may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or the Agents or of the Loan Parties hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent or the Collateral Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) forgive the principal amount or extend the final scheduled date of maturity of any Loan, reduce the stated rate of any interest or fee payable hereunder (except (x) in connection with the waiver of applicability of any post-default increase in interest rates and (y) that any amendment or


44

modification of defined terms used in the financial covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (i)) or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Lender's Commitment, in each case without the written consent of each Lender directly affected thereby;
(ii) eliminate or reduce the voting rights of any Lender under this Section 9.1 without the written consent of such Lender; (iii) reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Company of any of its rights and obligations under this Agreement and the other Loan Documents, release all or substantially all of the Collateral or release all or substantially all of the Subsidiary Guarantors from their obligations under the Guarantee and Collateral Agreement or the UK Charge Over Shares, as the case may be, in each case without the written consent of all Lenders; (iv) amend, modify or waive any provision of Section 9.7 without the written consent of all Lenders; and (v) amend, modify or waive any provision of

Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent, the Collateral Agent and all future holders of the Loans. In the case of any waiver, the Loan Parties, the Lenders, the Administrative Agent and the Collateral Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon.

46

any of the foregoing relating to the use of proceeds of the Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of any Group Member or any of the Properties (provided that such liability was incurred during such time as a Group Member controlled such Properties) and the reasonable fees and expenses of legal counsel in connection with claims, actions or proceedings by any Indemnitee against any Loan Party under any Loan Document (all the foregoing in this clause
(d), collectively, the "Indemnified Liabilities"), provided, that the Borrowers shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities have resulted from the gross negligence or willful misconduct of such Indemnitee. The payments by each Borrower pursuant to this Section 9.5 shall be in accordance with such Borrower's Proportionate Share. Without limiting the foregoing, and to the extent permitted by applicable law, the Company agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries to waive, all rights for contribution from any Indemnitee or any other rights of recovery from any Indemnitee with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section 9.5 shall be payable not later than 10 Business Days after written demand therefor and shall be accompanied by a statement setting forth in reasonable detail the source of such Indemnified Liability and the amount claimed thereunder. Statements payable by the Company pursuant to this Section 9.5 shall be submitted to Julian Cusack (Telephone No. 441-297-9715) (Telecopy No. 441-295-8201), at the address of the Company set forth in Section 9.2, or to such other Person or address as may be hereafter designated by the Company in a written notice to the Administrative Agent. The agreements in this Section 9.5 shall survive repayment of the Loans and all other amounts payable hereunder.

9.6 Successors and Assigns; Participations and Assignments. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by any Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.

(b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees (none of which may be a Borrower) (each, an "Assignee") all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

(A) the Company, provided that no consent of the Company shall be required for an assignment (1) to a Lender, an affiliate of a Lender or an Approved Fund (as defined below) or, (2) if an Event of Default has occurred and is continuing; and

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender, an affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender's Commitments or Loans, the amount of the Commitments or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with


47

respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Company and the Administrative Agent otherwise consent, provided that such amounts shall be aggregated in respect of each Lender and its affiliates or Approved Funds, if any;

(B) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(C) the Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire.

For the purposes of this Section 9.6, the term "Approved Fund" has the following meaning:

"Approved Fund" means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 9.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this
Section 9.6 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Assignee, the Assignee's completed administrative questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i) Any Lender may, without the consent of any Borrower or the Administrative


48

Agent, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it); provided that (A) such Lender's obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to the proviso to the second sentence of Section 9.1 and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.12, 2.13, 2.14 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.8 as though it were a Lender, provided such Participant shall be subject to Section 9.7 as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.12 or 2.13 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Company's prior written consent. Any Participant that is a Non-U.S. Lender shall not be entitled to the benefits of Section 2.13 unless such Participant complies with Section 2.13(d).

(d) Any Lender may at any time pledge or grant a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or grant to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or grant of a security interest; provided that no such pledge or grant of a security interest shall release such Lender from any of its obligations hereunder or substitute any such pledgee or grantee for such Lender as a party hereto and, provided, further, that nothing in this paragraph (d) shall be deemed to limit in any way the application of Section 9.6(b) to any assignment of the rights or obligations of such Lender under this Agreement resulting from a foreclosure of any such pledge or security interest.

(e) Each Borrower, upon receipt of written notice from the relevant Lender, agrees to issue Notes to any Lender requiring Notes to facilitate transactions of the type described in paragraph (d) above.

9.7 Adjustments. Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or to the Lenders, if any Lender (a "Benefitted Lender") shall receive any payment of all or part of the Obligations owing to it (whether directly from the Borrower, indirectly from any Guarantor pursuant to the Guarantee and Collateral Agreement or from the proceeds of the exercise of any remedies with respect to the Collateral pursuant to the Guarantee and Collateral Agreement or the UK Charge Over Shares or otherwise), or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off (whether against any Borrower or any Guarantor), pursuant to events or proceedings of the nature referred to in Section 7(g), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter


49

recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

9.8 Set-off. Upon the occurrence and continuation of an Event of Default, in addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to any Borrower, any such notice being expressly waived by each Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by any Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of a Borrower, as the case may be. Each Lender agrees promptly to notify the Company and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application.

9.9 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Company and the Administrative Agent.

9.10 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

9.11 Integration. This Agreement and the other Loan Documents represent the entire agreement of the Borrowers, the Administrative Agent, the Collateral Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent, the Collateral Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents.

9.12 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

9.13 Submission To Jurisdiction; Waivers. Each Borrower, the Administrative Agent, the Collateral Agent and each Lender hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or


50

proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the Borrowers, as the case may be at its address set forth in Section 9.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

9.14 Releases of Guarantees and Liens. (a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, the Collateral Agent is hereby irrevocably authorized by each Lender (without requirement of notice to or consent of any Lender except as expressly required by Section 9.1) to take any action requested by the Company having the effect of releasing any Collateral or guarantee obligations (i) to the extent necessary to permit consummation of any transaction not prohibited by any Loan Document or that has been consented to in accordance with Section 9.1 or (ii) under the circumstances described in paragraph (b) below.

(b) At such time as the Loans and the other obligations under the Loan Documents shall have been paid in full in cash and the Commitments have been terminated, the Collateral shall cease to secure the Obligations and, if at such time the Other Loans and the other obligations under the Loan Documents (as defined in the Other Credit Agreement) shall have been paid in full in cash and the Other Commitments have been terminated, the Collateral shall be released from the Liens created by the Security Documents, and the Security Documents and all obligations (other than those expressly stated to survive such termination) of the Administrative Agent, the Collateral Agent and each Loan Party under the Security Documents shall terminate, all without delivery of any instrument or performance of any act by any Person.

(c) At any such time as a Material Subsidiary ceases to meet the requirements set forth in the definition of Material Subsidiary for two consecutive fiscal quarters of the Company, the Company may, by giving written notice to the Collateral Agent, request a release from the Lien created by the Security Documents of any Pledged Stock issued by such Material Subsidiary, and the Collateral Agent shall (provided that no Event of Default shall have occurred and be continuing) execute all documents reasonably requested by the Company to effect such release and return any certificates representing such Pledged Stock to the Company, without recourse, representation or warranty, provided that no such releases shall be effected less than (a) 30 days following the receipt by the Lenders pursuant to Section 5.1 of the financial statements for the second of such fiscal quarters or (b) 60 days following the receipt by the Collateral Agent of the written notice requesting such release described above.

9.15 Confidentiality. Each of the Administrative Agent, the Collateral Agent and each Lender agrees to keep confidential all non-public information provided to it by any Group Member, the Administrative Agent, the Collateral Agent or any Lender pursuant to or in connection with this Agreement (the "Information"); provided that nothing herein shall prevent the Administrative Agent, the Collateral Agent or any Lender from disclosing any such Information
(a) to the Administrative Agent, the Collateral Agent, any other Lender or any affiliate thereof, (b) subject to an agreement to comply with the provisions of this Section, to any actual or prospective Transferee, (c) to its employees, directors, agents,


51

attorneys, accountants and other professional advisors or those of any of its affiliates, provided that such parties agree to comply with the provisions of this Section, (d) upon the request or demand of any Governmental Authority, provided that the Administrative Agent, the Collateral Agent or any Lender, as the case may be, requests confidential treatment of such Information to the extent permitted by law, (e) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, provided that the Administrative Agent, the Collateral Agent or any Lender, as the case may be, requests confidential treatment of such Information to the extent permitted by law, (f) if requested or required to do so in connection with any litigation or similar proceeding, provided that (1) the Administrative Agent, the Collateral Agent or any Lender, as the case may be, provides the Company with notice of such event promptly upon obtaining knowledge thereof (provided that the Administrative Agent, the Collateral Agent or any Lender, as the case may be, is not legally prohibited by law from giving such notice) so that the Company may seek a protective order or other appropriate remedy and (2) in the event that such protective order or other remedy is not obtained, the Administrative Agent, the Collateral Agent or any Lender, as the case may be, shall furnish only that portion of the Information that is legally required and shall disclose the Information in a manner reasonably designed to preserve its confidential nature, (g) that has been publicly disclosed other than as a result of (1) disclosure by the Administrative Agent, the Collateral Agent or any Lender in violation of this Agreement or (2) becoming available from a third party which to the knowledge of the Administrative Agent, the Collateral Agent or any Lender, as the case may be, is prohibited from disclosing such information pursuant to a contractual, legal or fiduciary obligation to the Company or a third party, (h) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender's investment portfolio in connection with ratings issued with respect to such Lender, or (i) in connection with the exercise of any remedy hereunder or under any other Loan Document. Notwithstanding anything herein to the contrary, any party to this Agreement (and any employee, representative, or other agent of any party to this Agreement) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure. However, any such Information relating to the tax treatment or tax structure is required to be kept confidential to the extent necessary to comply with any applicable federal or state securities laws.

Each Grantor hereby assigns and transfers to the Collateral Agent, and hereby grants to the Collateral Agent, for the benefit of the Administrative Agents and the Lenders, a security interest in, all of the following property now owned or at any time hereafter acquired by such Grantor or in which such Grantor now has or at any time in the future may acquire any right, title or interest (collectively, the "Collateral"), as collateral security for the prompt and complete payment and performance when due (whether at the stated maturity, by acceleration or otherwise) of (i) in the case of any Grantor which is a Guarantor, its Guarantor Obligations and (ii) in any other case, the Borrower Obligations:

(b) to the extent not otherwise included, all Proceeds of any and all of the foregoing.

For the avoidance of doubt, Collateral shall not include any Capital Stock of an Insurance Subsidiary which may not in accordance with applicable law be pledged because, despite the best efforts of the Company or the holder of such Capital Stock, the consents or approvals of any insurance commission or Governmental Authority necessary for the creation of the security interest in such Capital Stock were not obtained.

Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum amount secured hereunder and under the other Loan Documents by Liens created by any Grantor which is not a Borrower or a Guarantor shall in no event exceed the amount which can be secured by such Grantor under applicable Requirements of Law relating to the insolvency of debtors.

4.3 Jurisdiction of Organization; Chief Executive Office. On the date hereof, such Grantor's jurisdiction of organization, identification number from the jurisdiction of organization (if any), and the location of such Grantor's chief executive office or sole place of business or principal residence, as the case may be, are specified on Schedule 2.

SECTION 5. COVENANTS

Each Grantor covenants and agrees with the Collateral Agent, the Administrative Agents and the Lenders that, from and after the date of this Agreement until the Obligations shall have been paid in full and the Commitments shall have terminated:

5.5 Pledged Stock. (a) If such Grantor shall become entitled to receive or shall receive any certificate (including, without limitation, any stock certificate representing a stock dividend or a distribution in connection with any reclassification, increase or reduction of capital or any certificate issued in connection with any reorganization), warrant, option or rights in respect of the Capital Stock of any Pledged Material Subsidiary, whether in addition to, in substitution of, as a conversion of, or in exchange for, any shares of the Pledged Stock, or otherwise in respect thereof, such Grantor shall accept the same as the agent of the Collateral Agent, the Administrative Agents and the Lenders, hold the same in trust for the Collateral Agent for the benefit of the Administrative Agents and the Lenders and deliver the same forthwith to the Collateral Agent in the exact form received, duly indorsed by such Grantor to the Collateral Agent, if required, together with an undated stock power covering such certificate duly executed in blank by such Grantor to be held by the Collateral Agent, subject to the terms hereof, as additional collateral security for the Borrower Obligations or the applicable Guarantor Obligations, as the case may be. In case any distribution of capital shall be made on or in respect of the Pledged Stock of any Grantor or any property shall be distributed upon or with respect to the Pledged Stock of any Grantor pursuant to the recapitalization or reclassification of the capital of any Pledged Material Subsidiary or pursuant to the reorganization thereof, the property so distributed shall, unless otherwise subject to a perfected security interest in favor of the Collateral Agent, be delivered to the Collateral Agent to be held

(i) it will be bound by the terms of this Agreement and the Credit Agreements relating to the Capital Stock issued by it and will comply with such terms insofar as such terms are applicable to it, (ii) it will notify the Collateral Agent promptly in writing of the occurrence of any of the events described in Section 5.5(a) with respect to the Pledged Stock issued by it and (iii) the terms of Sections 6.1(c) shall apply to it, mutatis mutandis, with respect to all actions that may be required of it pursuant to Section 6.1(c) with respect to the Pledged Stock issued by it.

SECTION 6. REMEDIAL PROVISIONS

6.1 Pledged Stock. (a) Unless an Event of Default shall have occurred and be continuing and the Collateral Agent shall have given notice to the relevant Grantor of the Collateral Agent's intent to exercise its corresponding rights pursuant to Section 6.1(b), each Grantor shall be permitted to receive all cash dividends and other distributions (excluding any distributions set forth in Section 5.5(a)) paid in respect of the Pledged Stock in the normal course of business of the relevant Pledged Material Subsidiary and consistent with past practice, to the extent permitted in the Credit Agreements, and to exercise all voting and corporate or other organizational rights with respect to the Pledged Stock; provided, however, that no vote shall be cast or corporate or other organizational right exercised or other action taken which, in the Collateral Agent's reasonable judgment, would impair the Collateral or which would be inconsistent with or result in any violation of any provision of either Credit Agreement, this Agreement or any other Loan Document.

(b) If an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of its intent to exercise such rights to the relevant Grantor or Grantors, (i) the Collateral Agent shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Stock and make application thereof to the Borrower Obligations or the applicable Guarantor Obligations, as the case may be, in the order specified in Section 6.3, and (ii) to the extent permitted by applicable Requirements of Law, any or all of the Pledged Stock shall be registered in the name of the Collateral Agent or its nominee, and the Collateral Agent or its nominee may thereafter exercise
(x) all voting, corporate and other rights pertaining to such Pledged Stock at any meeting of shareholders of the relevant Pledged Material


10

Subsidiary or Pledged Material Subsidiaries and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Stock as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Stock upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other organizational structure of any Pledged Material Subsidiary, or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Pledged Stock, and in connection therewith, the right to deposit and deliver any and all of the Pledged Stock with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) Each Grantor hereby authorizes and instructs each Material Subsidiary which is the issuer of any Capital Stock pledged by such Grantor hereunder to (i) comply with any instruction received by it from the Collateral Agent in writing that (x) states that an Event of Default has occurred and is continuing and that the Collateral Agent, on behalf of the Lenders, is executing rights and remedies granted to them under this Agreement, and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that such Material Subsidiary shall be fully protected in so complying, and (ii) upon the occurrence and continuance of an Event of Default and notice from the Collateral Agent that the Collateral Agent, on behalf of the Administrative Agents and the Lenders, is executing rights and remedies granted to them under this Agreement unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Stock directly to the Collateral Agent.

6.2 Proceeds to be Turned Over To Collateral Agent. If an Event of Default shall occur and be continuing, all Proceeds received by any Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for the Collateral Agent for the benefit of the Administrative Agents and the Lenders, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Collateral Agent in the exact form received by such Grantor (duly indorsed by such Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent from a Grantor who is not a Guarantor hereunder shall be held by the Collateral Agent in a Collateral Account maintained under its sole dominion and control and all proceeds received by the Collateral Agent from a Grantor who is a Guarantor hereunder shall be held by the Collateral Agent in a separate Collateral Account maintained under its sole dominion and control. All Proceeds while held by the Collateral Agent in any Collateral Account (or by such Grantor in trust for the Collateral Agent for the benefit of the Administrative Agents and the Lenders) shall continue to be held as collateral security for the Borrower Obligations or the applicable Guarantor Obligations, as the case may be, and shall not constitute payment thereof until applied as provided in Section 6.3.

6.3 Application of Proceeds. (a) At any time when an Event of Default shall have occurred and be continuing, the Collateral Agent may apply all or any part of Proceeds constituting Collateral the security interest in which was granted by a Grantor who is not a Guarantor, whether or not held in any Collateral Account, and any proceeds of the guarantee set forth in Section 2, in payment of the Borrower Obligations in the following order:

First, to pay incurred and unpaid fees and expenses of the Collateral Agent and the Administrative Agents under the Loan Documents, pro rata among them in according to the amounts thereof then due and owing;


11

Second, to the Administrative Agents, for application by them towards payment of amounts then due and owing and remaining unpaid in respect of the Borrower Obligations, pro rata among the Lenders, according to the amounts of the Borrower Obligations then due and owing and remaining unpaid to the Lenders; and

Third, any balance of such Proceeds remaining after the Borrower Obligations shall have been paid in full and the Commitments shall have terminated shall be paid over to the applicable Grantor or to whomsoever may be lawfully entitled to receive the same.

(b) At any time when an Event of Default shall have occurred and be continuing, the Collateral Agent may apply all or any part of Proceeds constituting Collateral the security interest in which was granted by a Grantor who is a Guarantor, whether or not held in any Collateral Account, and any proceeds of the guarantee set forth in Section 2, in payment of its Guarantor Obligations in the following order:

First, to pay incurred and unpaid fees and expenses of the Collateral Agent and the Administrative Agents under the Loan Documents, pro rata among them in according to the amounts thereof then due and owing;

Second, to the Administrative Agents, for application by them towards payment of amounts then due and owing and remaining unpaid in respect of the Guarantor Obligations, pro rata among the Lenders, according to the amounts of the Guarantor Obligations then due and owing and remaining unpaid to the Lenders; and

Third, any balance of such Proceeds remaining after the Guarantor Obligations shall have been paid in full and the Commitments shall have terminated shall be paid over to the applicable Grantor or to whomsoever may be lawfully entitled to receive the same.

6.4 Code and Other Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the Administrative Agents and the Lenders, may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the New York UCC or any other applicable law. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels, at any office of the Collateral Agent or any Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent, either Administrative Agent or any Lender shall have the right to the extent permitted by law, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 6.4, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent, the Administrative Agents and the Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in the order specified in Section 6.3, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law,


12

including, without limitation, Section 9-615(a)(3) of the New York UCC, need the Collateral Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Collateral Agent, either Administrative Agent or any Lender arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 Business Days before such sale or other disposition.

Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Stock, by reason of certain prohibitions contained in the Securities Act, applicable state securities laws or the securities laws of any applicable jurisdiction, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges that any such private sale may result in prices and other terms less favorable than if such sale were a public sale. The Lenders understand and agree that this Agreement contains no provision requiring that any Grantor cause the Pledged Stock pledged by it to be registered under the Securities Act or any other applicable securities laws in connection with a sale thereof by the Collateral Agent pursuant to an exercise of its remedies provided for herein.

6.5 Deficiency. Each Grantor which is a Borrower or a Guarantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Borrower Obligations or the applicable Guarantor Obligations, as the case may be, and the fees and disbursements of any attorneys employed by the Collateral Agent, either Administrative Agent or any Lender to collect such deficiency.

6.6 Limitation of Rights. (a) Notwithstanding any other term or condition contained herein, the Collateral Agent recognizes that it may not exercise any of the rights or powers described herein with respect to the ownership, transfer, sale or voting of Collateral consisting of Pledged Stock of any Insurance Subsidiary, including the foreclosure upon or sale or transfer of such Collateral, unless and until the Collateral Agent (and, in the case of a sale of such Collateral, the purchaser thereof) has complied with the filing requirements of all Requirements of Law regulating the acquisition of voting securities or control of an Insurance Subsidiary, and the acquisition of such Collateral and control of the Insurance Subsidiary which is the issuer thereof by the Collateral Agent (or by the purchaser in any such sale) has been duly approved to the extent required by and in accordance with all such laws.

(b) Upon the occurrence and during the continuance of an Event of Default, any Borrowers and the Grantors (i) will take such actions as the Collateral Agent, on behalf of the Administrative Agents and the Lenders, may reasonably request in obtaining approval of the relevant insurance commission or other Governmental Authority, if required, for any action or transaction contemplated by this Agreement and (ii) in the case of any Pledged Material Subsidiary organized under the laws of Bermuda, to cause the board of directors of the Grantor of a Lien on the Capital Stock of such Pledged Material Subsidiary to approve any transfer or sale of the Pledged Stock issued thereby to the Collateral Agent (or, in the case of a sale of the Collateral, the purchaser thereof) upon obtaining any necessary approvals from each Governmental Authority required pursuant to all applicable Requirements of Law.

SECTION 7. THE COLLATERAL AGENT

7.1 Collateral Agent's Appointment as Attorney-in-Fact, etc. (a) Subject to the last sentence of this Section 7.1(a), each Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of


13

such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any or all of the following:

(i) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due with respect to any Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due with respect to any other Collateral whenever payable;

(ii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

(iii) execute, in connection with any sale provided for in Section 6.4, any indorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; and

(iv) (1) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (2) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (3) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (4) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (5) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Collateral Agent may deem appropriate; and
(6) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent's option and such Grantor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's, the Administrative Agents' and the Lenders' security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this Section 7.1(a) to the contrary notwithstanding, the Collateral Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 7.1(a) unless an Event of Default shall have occurred and be continuing and, if the rights to be exercised relate to the Capital Stock of an Insurance Subsidiary, unless all necessary filings and approvals, if any, described in Section 6.6 have been made and obtained.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement to the extent permitted by applicable law.

(c) The expenses of the Collateral Agent incurred in connection with actions


14

undertaken as provided in this Section 7.1, together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR Loans under either Credit Agreement, from the date of payment by the Collateral Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Collateral Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

7.2 Execution of Financing Statements. Pursuant to any applicable law, each Grantor authorizes the Collateral Agent to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral without the signature of such Grantor in such form and in such offices as the Collateral Agent determines appropriate to perfect the security interests of the Collateral Agent under this Agreement. Each Grantor hereby ratifies and authorizes the filing by the Collateral Agent of any financing statement with respect to the Collateral made prior to the date hereof.

7.3 Duty of Collateral Agent. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the New York UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, either Administrative Agent any Lender nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Collateral Agent, for the benefit of the Administrative Agents and the Lenders, hereunder are solely to protect the Collateral Agent's, the Administrative Agents and the Lenders' interests in the Collateral and shall not impose any duty upon the Collateral Agent, either Administrative Agent or any Lender to exercise or cause the exercise of any such powers. The Collateral Agent, the Administrative Agents and the Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

7.4 Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as among the Collateral Agent, the Administrative Agents and the Lenders, be governed by the Credit Agreements and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantors, the Collateral Agent shall be conclusively presumed to be acting as agent for the Administrative Agents and the Lenders with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

SECTION 8. MISCELLANEOUS

8.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 9.1 of the Credit Agreements.

8.2 Notices.

8.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Collateral Agent, either Administrative Agent nor any Lender shall by any act (except by a written instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, either Administrative Agent or any Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent, either Administrative Agent or any Lender of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent, either Administrative Agent or such Lender would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

8.4 Enforcement Expenses; Indemnification. (a) Each Guarantor jointly and severally agrees to pay or reimburse the Collateral Agent for all its costs and expenses incurred in collecting against such Guarantor under the guarantee contained in Section 2 or otherwise enforcing or preserving any rights under this Agreement and the other Loan Documents to which such Guarantor is a party, including, without limitation, the fees and disbursements of counsel (including the allocated fees and expenses of in-house counsel) to the Collateral Agent.

(c) Each Guarantor jointly and severally agrees to pay, and to save the Collateral Agent harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the extent any Borrowers would be required to do so pursuant to Section 9.5 of the Credit Agreements.

(d) The agreements in this Section 8.4 shall survive repayment of the Obligations and all other amounts payable under the Credit Agreements and the other Loan Documents.

8.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Guarantor and each Grantor and shall inure to the benefit of the Collateral Agent, the Administrative Agents and the Lenders and their successors and assigns permitted pursuant to the terms

of the Credit Facilities; provided that no Guarantor or Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Collateral Agent.

8.6 Set-Off. Each Guarantor hereby irrevocably authorizes the Collateral Agent, each Administrative Agent and each Lender at any time and from time to time upon the occurrence and continuation of an Event of Default pursuant to Section 7(a) of the Credit Agreements, without notice to such Guarantor or Grantor or any other Guarantor, any such notice being expressly waived by each Guarantor, to set-off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by the Collateral Agent, such Administrative Agent or such Lender to or for the credit or the account of such Guarantor, or any part thereof in such amounts as the Collateral Agent, such Administrative Agent or such Lender may elect, against and on account of the obligations and liabilities of such Guarantor to the Collateral Agent, such Administrative Agent or such Lender hereunder and claims of every nature and description of the Collateral Agent, such Administrative Agent or such Lender against such Guarantor, in any currency, whether arising hereunder, under the Credit Agreement, any other Loan Document or otherwise, as the Collateral Agent, such Administrative Agent, or such Lender may elect, whether or not the Collateral Agent, either Administrative Agent or any Lender has made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. The Collateral Agent, each Administrative Agent and each Lender shall notify such Guarantor promptly of any such set-off and the application made by the Collateral Agent, such Administrative Agent or such Lender of the proceeds thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Collateral Agent, each Administrative Agent and each Lender under this Section 8.6 are in addition to other rights and remedies (including, without limitation, other rights of set-off), which the Collateral Agent, such Administrative Agent or such Lender may have. Any amounts received by the Lenders through the exercise of the rights of set-off provided for in this Section 8.6 shall be subject to the sharing requirements of Section 9.7 of the Credit Agreements to which each Guarantor hereby expressly consents.

8.7 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

8.8 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

8.9 Section Headings. The Section headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

8.10 Integration. This Agreement and the other Loan Documents represent the agreement of the Guarantors, the Grantors, the Collateral Agent, the Administrative Agents and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Collateral Agent, either Administrative Agent or any Lender relative to subject matter hereof and thereof not expressly set forth or referred to herein or in the other Loan Documents.

17

AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

8.12 Submission To Jurisdiction; Waivers. The Collateral Agent, each Administrative Agent, each Lender, each Guarantor and each Grantor hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) in the case of each Guarantor and each Grantor, agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Guarantor or Grantor at its address referred to in Section 8.2 or at such other address of which the Collateral Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents to which it is a party;

(b) neither the Collateral Agent, either Administrative Agent nor any Lender has any fiduciary relationship with or duty to any Guarantor or Grantor arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Guarantors or Grantors, on the one hand, and the Collateral Agent, the Administrative Agents and Lenders, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Guarantors and the Grantors and the Lenders.

8.14 Additional Guarantor and Grantors. Each Subsidiary of the Company that is required to become a Grantor or a Guarantor under this Agreement pursuant to Section 5.4 or Section 5.10, as the case may be, of either Credit Agreement shall become (a) a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption Agreement substantially in the form of Annex 2 hereto and/or (b) a Guarantor for all purposes of this Agreement upon execution and


18

delivery of a Joinder substantially in the form of Annex 3 hereto.

8.15 Releases. (a) At such time as the Loans and the other Obligations shall have been paid in full, the Commitments have been terminated, the Collateral shall be released from the Liens created hereby, and this Agreement and all obligations (other than those expressly stated to survive such termination) of the Collateral Agent and each Guarantor and Grantor hereunder shall terminate, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to the Grantors. Following any such termination, the Collateral Agent shall deliver to such Grantor any Collateral held by the Collateral Agent hereunder, and execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination at such Grantor's expense.

(b) If any of the Collateral shall be sold, transferred or otherwise disposed of by any Grantor in a transaction permitted by the Credit Agreements, then the Collateral Agent, at the request and sole expense of such Grantor, shall execute and deliver to such Grantor all releases or other documents reasonably necessary or desirable for the release of the Liens created hereby on such Collateral. At the request and sole expense of any Borrower, a Guarantor shall be released from its obligations hereunder in the event that all the Capital Stock of such Guarantor shall be sold, transferred or otherwise disposed of in a transaction permitted by the Credit Agreements; provided that any Borrower shall have delivered to the Collateral Agent, at least ten Business Days prior to the date of the proposed release, a written request for release identifying the relevant Guarantor and the terms of the sale or other disposition in reasonable detail, including the price thereof and any expenses in connection therewith, together with a certification by any Borrower stating that such transaction is in compliance with the Credit Agreements and the other Loan Documents.

(c) At any such time as a Pledged Material Subsidiary ceases to meet the requirements set forth in the definition of Material Subsidiary for two consecutive fiscal quarters of the Company, any Lien created hereunder on Pledged Stock issued by such Pledged Material Subsidiary shall be released and any certificates representing the Pledged Stock shall be returned in accordance with and to the extent provided in Section 9.14(c) of the Credit Agreements.

8.16 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

14. COSTS AND EXPENSES

(b) any amendment, consent or suspension of rights (or proposal for any of the same) relating to this deed (and documents, matters or things referred to in this deed); and

14.2 ENFORCEMENT EXPENSES

The Charging Company will on demand pay to each of the Administrative Agents, the Collateral Agent and any Receiver the amount of all costs and expenses (including legal fees and other out of pocket expenses and any value added tax or other similar tax thereon) reasonably incurred by

15. CUMULATIVE POWERS AND AVOIDANCE OF PAYMENTS

If any amount paid in respect of the Indebtedness is capable of being avoided or set aside, then for the purposes of this deed that amount shall not be considered to have been paid.

Any settlement or discharge between the Charging Company and the Administrative Agents or the Collateral Agent shall be conditional upon no security or payment to the Administrative Agent or Collateral Agent by the Charging Company or any other person being avoided, set aside, ordered to be refunded or reduced by virtue of any provision or enactment relating to insolvency and accordingly the Administrative Agent and the Collateral Agent, as the case may be, shall be entitled to recover from the Charging Company the value which the Administrative Agent and the Collateral Agent, as the case may be, has placed on that security or the amount of any such payment as if that settlement or discharge had not occurred.


16. RULING OFF ACCOUNTS

If the Collateral Agent receives notice of any subsequent Liens or other interest affecting any of the Charged Property (except as permitted by each of the Credit Agreements) it may open a new account for the Charging Company in its books. If it does not do so then (unless it gives express notice to the contrary to the Charging Company), as from the time it receives that notice, all payments made by the Charging Company to it (in the absence of any express appropriation to the contrary) shall be treated as having been credited to a new account of the relevant Charging Company and not as having been applied in reduction of the Indebtedness.

17. DELEGATION

The Collateral Agent may delegate by power of attorney or in any other manner all or any of the powers, authorities and discretions which are for the time being exercisable by it under this deed to any person or persons upon such terms and conditions (including the power to sub-delegate) as it may think fit. The Collateral Agent will not be liable or responsible to the Charging Company or any other person for the negligence or misconduct on the part of any delegate selected by it with reasonable care.

18. REDEMPTION OF PRIOR CHARGES

The Collateral Agent may, at any time after an Event of Default has occurred, redeem any prior Lien on or relating to any of the Charged Property or procure the transfer of that Lien to itself, and may settle and pass the accounts of any person entitled to that prior Lien. Any account so settled and passed shall (subject to any manifest error) be conclusive and binding on the Charging Company. The Charging Company will on demand pay to the Collateral Agent all principal monies and interest and all losses incidental to any such redemption or transfer.

19. RELEASE

19.1 At such time as all the Indebtedness has been unconditionally and irrevocably discharged in full and the Lenders have no further contingent obligations to lend under or in connection with the Credit Agreements, the Collateral Agent shall at the request and cost of the Charging Company execute such documents (or procure that its nominees execute such documents) as the Charging Company may reasonably request and which may be required to discharge all the charges created by this deed and return any certificates representing the Charged Property to the Charging Company.

19.2 At any such time as a Material Subsidiary ceases to meet the requirements set forth in the definition of Material Subsidiary for two consecutive fiscal quarters of the Company, any Lien created hereunder on Charged Property issued by such Material Subsidiary shall be released in accordance with and to the extent provided in Section 9.13(c) of each Credit Agreement.


20. NOTICES

20.1 MODE OF SERVICE

(a) Any notice, demand, consent, agreement or other communication (a "NOTICE") to be served in connection with this deed will be in writing and will be made by letter or by facsimile transmission to the party to be served.

21.1 ASSIGNMENT BY THE ADMINISTRATIVE AGENTS AND THE COLLATERAL AGENT

The Administrative Agents and the Collateral Agent may at any time assign, delegate or otherwise transfer all or any part of its rights under this deed in accordance with the Credit Agreements.


22. CURRENCY CLAUSES

22.1 CONVERSION

All monies received or held by the Administrative Agents, the Collateral Agent or any Receiver under this deed may be converted into any other currency which the Administrative Agents or the Collateral Agent considers necessary to cover the obligations and liabilities comprised in the Indebtedness in that other currency at the Administrative Agents' or Collateral Agent's spot rate of exchange then prevailing for purchasing that other currency with the existing currency.

22.2 NO DISCHARGE

No payment to the Administrative Agents or to the Collateral Agent (whether under any judgement or court order or otherwise) shall discharge the obligation or liability of the Charging Company in respect of which it was made unless and until the Administrative Agents or the Collateral Agent has received payment in full in the currency in which the obligation or liability was incurred. To the extent that the amount of any such payment shall on actual conversion into that currency fall short of that obligation or liability expressed in that currency, the Administrative Agents and the Collateral Agent shall have a further separate cause of action against the Charging Company and shall be entitled to enforce the security constituted by this deed to recover the amount of the shortfall.

23. MISCELLANEOUS

23.1 SMALL COMPANY MORATORIUM

Notwithstanding any other provision of this deed, the obtaining of a moratorium under section 1A of the Insolvency Act 1986, or anything done with a view to obtaining such a moratorium (including any preliminary decision or investigation), shall not be an event causing any floating charge created by this deed to crystallise or causing restrictions which would not otherwise apply to be imposed on the disposal of property by the Charging Company or a ground for the appointment of a Receiver.

23.2 CERTIFICATES CONCLUSIVE

A certificate or determination of the Administrative Agents or the Collateral Agent as to any amount payable under this deed will be conclusive and binding on the Charging Company, except in the case of manifest error.

23.3 INVALIDITY OF ANY PROVISION

If any provision of this deed is or becomes invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining provisions shall not be affected or impaired in any way.

The perpetuity period applicable to the trusts created by this deed is 80 years.

23.6 THIRD PARTY RIGHTS

The Contracts (Rights of Third Parties) Act 1999 shall not apply to this deed and no person other than the parties to this deed shall have any rights under it, nor shall it be enforceable under that Act by any person other than the parties to it.

24.2 The Charging Company, for the benefit of the Administrative Agents and the Collateral Agent, irrevocably submits to the jurisdiction of the courts in England for the purpose of hearing and determining any dispute arising out of this deed and for the purpose of enforcement of any judgment against its assets.

24.3 The submission to the jurisdiction of the courts referred to in clause 24.2 shall not (and shall not be construed so as to) limit the right of the Administrative Agents or the Collateral Agent to take proceedings against the Charging Company in any other court of competent jurisdiction nor shall the taking of proceedings in any one or more jurisdictions preclude the taking of proceedings in any other jurisdiction (whether concurrently or not) if and to the extent permitted by applicable law.

24.4 Without prejudice to any other permitted mode of service, the Charging Company agrees that service of any claim form, notice or other document for the purpose of any proceedings in such courts shall be duly served upon it if delivered or sent by registered post to LeBoeuf Lamb Greene & MacRae, of 6th floor, 1 Minster Court, Mincing Lane, EC3R 7YL, London, United Kingdom (marked for the attention of the Managing Partner).

Each Borrower agrees to pay its pro rata share (calculated, for any day, based on the percentage which the principal amount of the Loans outstanding to such Borrower at the close of business on such day constitutes of the then aggregate principal amount of the Loans to all Borrowers (in the case of each Borrower, its "Proportionate Share")), provided, that at any time when no Loans are outstanding, the pro rata share of the Company shall be deemed to be 100%) to the Administrative Agent for the account of each Lender which has a then effective Commitment or a then outstanding Loan a facility fee (a "Facility Fee") for the period from and including the date hereof to the last day upon which such Lender's Commitment shall have terminated and such Lender's Loans shall have been paid in full, computed at the Facility Fee Rate on the average daily amount of the Commitment of such Lender (whether or not utilized) during the period (the "Computation Period") for which payment is made (or, if any Lender continues to have any Loans after its Commitment terminates, on the average daily amount of such Lender's Loans from and including the date on which its Commitment terminates to but excluding the date on which such Lender ceases to have any Loans outstanding), payable quarterly in arrears on each Fee Payment Date, commencing on the first such date to occur after the date hereof.

(b) The Borrowers agree to pay to the Administrative Agent for the account of each Lender, in arrears on each Fee Payment Date, a utilization fee (a "Utilization Fee") based upon the average daily amount of the outstanding Loans of such Lender at a rate per annum equal to the Utilization Fee Rate when and for as long as the aggregate outstanding principal amount of the sum of (a) the Loans hereunder plus (b) the aggregate principal amount of the Loans (as defined therein) under the Other Credit Agreement exceeds 60% of the sum of (x) the aggregate Commitments hereunder and (y) the aggregate amount of the Commitments (as defined therein) under the Other Credit Agreement. Payments made by the Borrowers hereunder shall be made in accordance with each Borrower's Proportionate Share.

(c) The Company agrees to pay to the Administrative Agent the fees in the amounts and on the dates as set forth in any fee agreements with the Administrative Agent and to perform any other obligations contained therein.

2.4 Termination or Reduction of Commitments. The Company shall have the right, upon not less than five Business Days' notice to the Administrative Agent, to terminate the Commitments or, from time to time, to reduce the amount of the Commitments; provided that no such termination or reduction of Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof, the Total Loans would exceed the Total Commitments. Any such reduction shall be in an amount equal to $5,000,000, or a whole multiple thereof, and shall reduce permanently the Commitments then in effect.


16

2.5 Optional Prepayments. Each Borrower may at any time and from time to time prepay the Loans made by the Lenders to such Borrower, in whole or in part, without premium or penalty, upon irrevocable notice delivered by the Company to the Administrative Agent no later than 2:00 P.M., London time, three Business Days prior thereto, in the case of Eurodollar Loans, and no later than 2:00 P.M., London time, one Business Day prior thereto, in the case of ABR Loans, which notice shall specify the date and amount of prepayment and whether the prepayment is of Eurodollar Loans or ABR Loans; provided, that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, such Borrower shall also pay any amounts owing pursuant to Section 2.14. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Loans that are ABR Loans) accrued interest to such date on the amount prepaid. Partial prepayments of ABR Loans and Eurodollar Loans for all Borrowers shall be in an aggregate principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof.

2.6 Conversion and Continuation Options. (a) The Company may elect from time to time to convert Eurodollar Loans to ABR Loans by giving the Administrative Agent prior irrevocable notice of such election substantially in the form of Exhibit I no later than 2:00 P.M., London time, on the proposed conversion date, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Company may elect from time to time to convert ABR Loans to Eurodollar Loans by giving the Administrative Agent prior irrevocable notice of such election no later than 2:00 P.M., London time, on the third Business Day preceding the proposed conversion date (which notice shall specify the length of the initial Interest Period therefor), provided that no ABR Loan may be converted into a Eurodollar Loan when any Event of Default or Default has occurred and is continuing and the Administrative Agent or the Required Lenders have determined in its or their sole discretion not to permit such conversions. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Company giving irrevocable notice to the Administrative Agent, substantially in the form of Exhibit I hereto in accordance with the applicable provisions of the term "Interest Period" set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans, provided that no Eurodollar Loan may be continued as such when any Event of Default or Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations, and provided, further, that if the Company shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Loans shall be automatically converted to ABR Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

2.7 Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations of Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than ten Eurodollar Tranches shall be outstanding at any one time.

2.8 Interest Rates and Payment Dates. Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin.


17

(b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin.

(c) (i) So long as any Event of Default shall have occurred and be continuing, the principal amount of all Loans shall bear interest at a rate per annum equal to the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% and (ii) if all or a portion of any interest payable on any Loan or any Facility Fee or Utilization Fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to ABR Loans plus 2%, in each case as described in this clause (ii), from the date of such non-payment until such amount is paid in full (as well after as before judgment).

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this Section shall be payable from time to time on demand.

2.9 Computation of Interest and Fees. (a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to ABR Loans the rate of interest on which is calculated on the basis of the Federal Funds Effective Rate, the interest thereon shall be calculated on the basis of a 365- (or 366, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Company and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Company and the relevant Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on each Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall deliver to the Company a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.8(a).

2.10 Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon each Borrower absent manifest error) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Company and the relevant Lenders as soon as practicable thereafter. Upon receipt of such notice, the Borrower may revoke any notice of borrowing, conversion or continuation then submitted by it. If the Borrower does not revoke such notice, then (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar


18

Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Company have the right to convert Loans to Eurodollar Loans.

2.11 Pro Rata Treatment and Payments. (a) Each borrowing by any Borrower from the Lenders hereunder and any reduction of the Commitments of the Lenders shall be made pro rata according to the Lenders' respective Commitments, and each payment by any Borrower on account of any Facility Fee or Utilization Fee shall be made pro rata to each Lender according to the respective amounts thereof owing pursuant to Section 2.3(a) or Section 2.3(b), as the case may be.

(b) Each payment (including each prepayment) by any Borrower on account of principal of and interest on the Loans made to it shall be made pro rata according to the respective outstanding principal amounts of such Loans then held by the Lenders.

(c) All payments (including prepayments) to be made by any Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 5:00 P.M., London time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(d) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon, at a rate equal to the greater of (i) the Federal Funds Effective Rate and (ii) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender's share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans, on demand, from the Borrowers.

(e) Unless the Administrative Agent shall have been notified in writing by the Company prior to the date of any payment due to be made by any Borrower hereunder that such Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that such Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by such Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on


19

demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against such Borrower.

2.12 Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.13 and changes in the rate of tax on the overall net income of such Lender);

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate; or

(iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost (excluding taxes) to such Lender, by an amount that such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower to which such Loans were made shall pay such Lender any additional amounts necessary to compensate such Lender for such increased cost (excluding taxes) or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly notify the Company (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of its obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Company (with a copy to the Administrative Agent) of a written request therefor, the Company shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction.

(c) A certificate as to any additional amounts payable pursuant to this
Section submitted by any Lender to the Company (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The Borrower shall pay such Lender the amount shown as due on such certificate within 10 Business Days after receipt by the Borrower. Notwithstanding anything to the contrary in this Section, the Company shall not be required to compensate a Lender pursuant to this Section for any amounts incurred more than three months prior to the date that such Lender notifies the


20

Company of such Lender's intention to claim compensation therefor; provided that, if the circumstances giving rise to such claim have a retroactive effect, then such three-month period shall be extended to include the period of such retroactive effect. The obligations of the Company pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.13 Taxes. All payments made by (or on behalf of) any Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding Excluded Taxes. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") or Other Taxes are required to be deducted or withheld from any amounts payable to the Administrative Agent or any Lender hereunder,
(i) the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, (ii) the Borrower shall deduct or withhold such amounts and
(iii) the Borrower shall pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law; provided, however, that no Borrower shall be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes that are attributable to such Lender's failure to comply with the requirements of paragraph (e) of this Section.

(b) In addition, each Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Each Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Non-Excluded Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of such Borrower hereunder (including Non-Excluded Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this
Section 2.13) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Non-Excluded Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to such Borrower by a Lender or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) Whenever any Non-Excluded Taxes or Other Taxes are payable by a Borrower, as promptly as possible thereafter such Borrower shall send to the Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by such Borrower showing payment thereof.

(e) A Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender's judgment such completion, execution or submission would not materially prejudice the legal position of such Lender. To the extent the Borrower is a "U.S. Person" as defined in Section 7701(a)(30) of the Code (a "U.S. Borrower"), each Lender (or Transferee) that is not a U.S. Person (a "Non-U.S. Lender") shall deliver to


21

the U.S. Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN, Form W-8ECI or, in the case of a Transferee, a Form W-81MY, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under
Section 871(h) or 881(c) of the Code with respect to payments of "portfolio interest", a statement substantially in the form of Exhibit F and a Form W-8BEN or, in the case of a Transferee, a Form W-8IMY, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the U.S. Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender within 10 Business Days of the request by the U.S. Borrower. Each Non-U.S. Lender shall promptly notify the U.S. Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the U.S. Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). If any Non-U.S. Lender provides a Form W-8IMY, such Non-U.S. Lender must also attach the additional documentation that must be transmitted with the Form W-8IMY, including the appropriate forms described in this Section 2.13(e).

(f) The agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.14 Indemnity. Each Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that such Lender may sustain or incur as a consequence of (a) default by such Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Company has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by such Borrower in making any prepayment of or conversion from Eurodollar Loans after the Company has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

2.15 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.12 or 2.13(a) with respect to such Lender, it will, if requested by the Company, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event or assign its rights and obligations hereunder to an Affiliate with the object of avoiding the consequences of such event; provided, that such designation or assignment is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) or such Affiliate, as the case may be, to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of any Borrower or the rights of any Lender pursuant to Section 2.12 or 2.13(a).

2.16 Replacement of Lenders. The Company shall be permitted to replace any Lender


22

that (a) requests reimbursement for amounts owing pursuant to Section 2.12 or 2.13(a) or (b) defaults in its obligation to make Loans hereunder, with a replacement financial institution; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default or Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement, such Lender shall, within 30 days of the Company's request have taken no action under Section 2.15 that eliminates the continued need for payment of amounts owing pursuant to Section 2.12 or 2.13(a), (iv) the replacement financial institution shall purchase, at par, all Loans and other amounts (including accrued interest) owing to such replaced Lender on or prior to the date of replacement, (v) the Borrowers shall be liable to such replaced Lender under Section 2.14 if any Eurodollar Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto as if it were prepaid on the date of such purchase, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 9.6 (provided that each Borrower shall be obligated to pay the portion of the registration and processing fee referred to therein based on such Borrower's Proportionate Share), (viii) until such time as such replacement shall be consummated, the Borrowers shall pay all additional amounts (if any) required pursuant to Section 2.12 or 2.13(a), as the case may be, and (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

Section 3. REPRESENTATIONS AND WARRANTIES

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Loans, the Company hereby represents and warrants to the Administrative Agent and each Lender that:

3.1 Financial Condition. The audited consolidated balance sheet of the Company and its Subsidiaries as at December 31, 2002, and the related consolidated statement of comprehensive income and of cash flows for the fiscal year ended on such date, reported on by and accompanied by an unqualified report from KPMG Audit Plc, present fairly the consolidated financial condition of the Company and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The unaudited consolidated balance sheet of the Company and its Subsidiaries as at March 31, 2003, and the related unaudited consolidated statements of comprehensive income and cash flows for the three-month period ended on such date, present fairly the consolidated financial condition of the Company and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the three-month period then ended (subject to normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). No Group Member has any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or unusual forward or long-term commitments, including any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the period from December 31, 2002 to and including the date of this Agreement there has been no Disposition by any Group Member of any material part of its business or property.

3.2 No Change. Since December 31, 2002, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

Neither the Company nor any Subsidiary is subject to any Private Act.

3.4 Power; Authorization; Enforceable Obligations. (a) Subject to obtaining any consent set forth in Part II of Schedule 3.4 (unless an Applicable Amendment shall have become effective) prior to a Consent Event, each Loan Party has or will have the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of each Borrower, to obtain Loans hereunder, and each Loan Party has or will have taken all necessary organizational action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of each Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the Loans hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, except (A)(x) consents, authorizations, filings and notices described in Part I of Schedule 3.4, which consents, authorizations, filings and notices have been obtained or, except as noted therein, made and are in full force and effect and (y) the consents described in Part II of Schedule 3.4 (unless an Applicable Amendment shall have become effective) which consents (or amendment or amendments, as the case may be) will be obtained prior to a Consent Event, (B) consents of any applicable Governmental Authority (including, where applicable, the Bermuda Monetary Authority, the U.K. Financial Services Authority and any relevant insurance commission or analogous Governmental Authority in the United States) required in the event of the exercise by the Collateral Agent of any right (1) to control or to allow any assignee of the Collateral Agent to control any Insurance Subsidiary or (2) to sell or transfer in accordance with the terms and conditions of any Security Document any Capital Stock of any Insurance Subsidiary pledged in accordance with the terms of such Security Document (including, in such case, any consent required for the purchaser or the transferee of such Capital Stock) and (C) any consent or authorization of, filing with or notice to, the relevant insurance commission or other Governmental Authority pursuant to any applicable Requirement of Law in connection with the creation subsequent to the Closing Date in accordance with
Section 5.4 of a security interest in the Capital Stock of any Material Subsidiary which is an Insurance Subsidiary. Each Loan Document has been duly executed and delivered on behalf of each Loan Party which is a party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party which is a party thereto, enforceable against each Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

(b) Under the laws of Bermuda in force at the date hereof, none of the Borrowers nor any Subsidiary Guarantor will be required to make any deduction or withholding from any payment it may make hereunder or under the Notes.

(c) Under the laws of Bermuda, the claims of the Collateral Agent and the Lenders against each Borrower and each Subsidiary Guarantor under this Agreement and the Notes will rank at least pari passu with the claims of all its other unsecured creditors, except creditors whose claims are preferred solely by any bankruptcy, insolvency or other similar law of general application governing the enforcement of creditors' rights.


24

(d) In any proceedings taken in Bermuda in relation to this Agreement, the choice of New York law as the governing law of this Agreement, and any judgment obtained in the United States, will be recognized and enforced.

Subject to obtaining any consents which may be required pursuant to Part II of Schedule 3.4 (unless an Applicable Amendment shall have become effective), the execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law (assuming compliance with any Requirement of Law relating to the consent of any Governmental Authority required in the event of the exercise by the Collateral Agent or any assignee of the Collateral Agent of any right to control any Insurance Subsidiary or to sell or transfer any Capital Stock of any Insurance Subsidiary in accordance with the terms and conditions of any Security Document (including, in such case, any consent required for the purchaser or the transferee of such Capital Stock)) or any Contractual Obligation of any Group Member and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents and except, in the case of Contractual Obligations, to the extent that the failure of any of the statements in this
Section 3.5 to be accurate could not reasonably be expected to have a Material Adverse Effect).

3.6 Litigation. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending, or, to the knowledge of any Borrower, threatened, by or against any Group Member or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

None of the Borrowers nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and none of the Borrowers nor any Commonly Controlled Entity would become subject to any material liability under ERISA if such Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

3.16 Accuracy of Information, etc. To the best of the Company's knowledge, the Confidential Information Memorandum, taken as a whole, is correct in all material respects as of the date thereof and does not, as of the date thereof, contain any untrue statement of a material fact or omit any material fact necessary to make the statements therein (taken as a whole) not misleading as of such date in light of the circumstances under which they made; provided, however, that this representation does not extend to (i) financial projections and other forward looking statements contained in the Confidential Information Memorandum (the "Projections") and (ii) information in the Confidential Information Memorandum which is referenced to a specific source or derived from public or other sources. The Projections contained in the Confidential Information Memorandum have been prepared in good faith based upon assumptions reasonably believed by the Company to be reasonable, it being understood, and the Administrative Agent and each Lender understands that the Projections are subject to significant uncertainties and contingencies many of which are beyond the control of the Company and there can be no assurances that such Projections will be realized.

No written statement or information delivered by any Loan Party to the Administrative Agent, the Collateral Agent or the Lenders contained in this Agreement or any other Loan Document, taken as a whole, contains any untrue statement of a material fact or omits any material fact necessary to make the statements therein (taken as a whole) not misleading as of the date of such statement or information in light of the circumstances under which they were provided.

3.17 Security Documents. The Guarantee and Collateral Agreement is effective to create in favor of the Collateral Agent, for the benefit of the Lenders, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof subject to (i) the consent of any applicable Governmental Authority required by any applicable Requirement of Law in the event of the exercise by the Collateral Agent of any right (A) to control or to allow any assignee of the Collateral Agent to control any Insurance Subsidiary or (B) to sell or transfer any Capital Stock (including, in such case, any consent required for the purchaser or the transferee of such Capital Stock). In the case of the Pledged Stock described in the Guarantee and Collateral Agreement, when stock certificates representing such Pledged Stock are delivered to the Collateral Agent and Uniform Commercial Code financing statements are filed in the applicable filing offices, the Guarantee and Collateral Agreement shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties organized under the laws of the United States in such Collateral and the proceeds thereof, as security for the Obligations (as defined in the Guarantee and Collateral Agreement), in each case prior and superior in right to any other Person. A priority interest in the Collateral of any Material Subsidiary organized under the laws of Bermuda will be created in Bermuda upon the registration of a charge with the Registrar of Companies.

Section 8. THE AGENTS

8.1 Appointment. Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents and the Collateral Agent as the agent of such Lender, the Administrative Agent, the Other Administrative Agent and the Other Lenders under the Security Documents, and each such Lender irrevocably authorizes the Administrative Agent and the Collateral Agent, as the case may be, in such capacities, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents, as applicable, and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent and the Collateral Agent, as the case may be, by the terms of this Agreement and the other Loan Documents, as applicable (and, in the case of the Collateral Agent, the Other Credit Agreement and the Security Documents), together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, neither the Administrative Agent nor the Collateral Agent shall have any duties or responsibilities, except those expressly set forth herein (and, in the case of the Collateral Agent, in the Other Credit Agreement), or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent or the Collateral Agent.

The Administrative Agent and each Lender understand and agree that all Liens created by the Security Documents on the Collateral have been created in favor of the Collateral Agent, for the benefit of the Administrative Agent, the Other Administrative Agent, the Lenders and the Other Lenders, that all rights to take remedial action with respect to the Collateral under the Security Documents have been granted to the Collateral Agent and that neither the Administrative Agent, the Other Administrative Agent, any Lender nor any Other Lender has the right to take any such remedial action with respect to the Collateral other than through the Collateral Agent.

8.2 Delegation of Duties. The Administrative Agent and the Collateral Agent may each execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. Neither the Administrative Agent nor the Collateral Agent shall be responsible for the negligence or misconduct of any agents or attorneys in-fact selected by it with reasonable care.

8.3 Exculpatory Provisions. Neither any Agent nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing have resulted from its or such Person's own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any


40

recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party a party thereto to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party.

8.4 Reliance. (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrowers), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

(b) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrowers), independent accountants and other experts selected by the Collateral Agent. The Collateral Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Collateral Agent shall be fully justified in failing or refusing to take any action under any Security Document unless it shall first receive the direction of the Administrative Agent under Section 7 of this Agreement and the Other Administrative Agent under Section 7 of the Other Credit Agreement, as applicable, or such advice or concurrence of (x) the Required Lenders (or, if so specified by this Agreement, all Lenders) and (y) the Required Lenders (as defined in the Other Credit Agreement) (or, if so specified by the Other Credit Agreement, all Other Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders and the Other Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under the Security Documents at the direction of the Administrative Agent under Section 7 of this Agreement and the Other Administrative Agent under Section 7 of the Other Credit Agreement, as applicable, or in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders) and the Required Lenders (as defined in the Other Credit Agreement) (or, if so specified by the Other Credit Agreement, all Other Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.


41

8.5 Notice of Default. (a) The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless it has received notice from a Lender or the Company referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

(b) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless it has received notice from the Administrative Agent, a Lender or the Company referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". The Collateral Agent shall take action with respect to such Default or Event of Default as shall be reasonably directed by the Administrative Agent under Section 7 of this Agreement and the Other Administrative Agent under Section 7 of the Other Credit Agreement, as applicable, or by (x) the Required Lenders (or, if so specified by this Agreement, all Lenders) and (y) the Required Lenders (as defined in the Other Credit Agreement) (or, if so specified by the Other Credit Agreement, all Other Lenders); provided that unless and until the Collateral Agent shall have received such directions, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders and the Other Lenders.

8.6 Non-Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that neither the Agents nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, neither the Administrative Agent nor the Collateral Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan Party or any affiliate of a Loan Party that may come into the possession of the Administrative Agent or the Collateral Agent or any of its respective officers, directors, employees, agents, attorneys-in-fact or affiliates.

8.7 Indemnification. (a) The Lenders agree to indemnify each Agent (other than the Collateral Agent) in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation of each Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if


42

indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent's gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

(b) The Lenders agree to indemnify the Collateral Agent in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation of each Borrower to do so), ratably according to the respective percentages which (i) the Aggregate Exposure of each Lender constitutes of (ii) the sum of (x) the Aggregate Exposure of all Lenders and (y) the Other Aggregate Exposure of all Other Lenders in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments and/or Other Commitments shall have terminated and the Loans and/or Other Loans shall have been paid in full, ratably in accordance with such percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Collateral Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Collateral Agent's gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder.

8.8 Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Loans made or renewed by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms "Lender" and "Lenders" shall include each Agent in its individual capacity.

8.9 Successor Administrative Agent and Collateral Agent. (a) The Administrative Agent may resign as Administrative Agent upon 30 days' notice to the Lenders and the Company. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 7(a) or Section 7(g) with respect to any Borrower shall have occurred and be continuing) be subject to approval by the Company (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent and the term "Administrative Agent" shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent's rights, powers and duties as Administrative Agent shall be terminated, without


43

any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 30 days following a retiring Administrative Agent's notice of resignation, the retiring Administrative Agent's resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders under this Agreement appoint a successor agent as provided for above. After any retiring Administrative Agent's resignation as Administrative Agent the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

(b) The Collateral Agent may resign as Collateral Agent upon 30 days' notice to the Lenders, the Other Lenders and the Company. If the Collateral Agent shall resign as Collateral Agent under this Agreement, then (x) the Required Lenders under this Agreement and (y) the Required Lenders (as defined therein) under the Other Credit Agreement shall appoint from among the Lenders a successor collateral agent, which successor collateral agent shall (unless an Event of Default under Section 7(a) or Section 7(g) with respect to any Borrower shall have occurred and be continuing) be subject to approval by the Company (which approval shall not be unreasonably withheld or delayed), whereupon such successor collateral agent shall succeed to the rights, powers and duties of the Collateral Agent and the term "Collateral Agent" shall mean such successor collateral agent effective upon such appointment and approval, and the former Collateral Agent's rights, powers and duties as Collateral Agent shall be terminated, without any other or further act or deed on the part of such former Collateral Agent or any of the parties to this Agreement or any holders of the Loans. If no successor collateral agent has accepted appointment as Collateral Agent by the date that is 30 days following a retiring Collateral Agent's notice of resignation, the retiring Collateral Agent's resignation shall nevertheless thereupon become effective, and the retiring Collateral Agent (after consultation with the Company) may appoint a financial institution rated at least `A' by S&P or `A' by Moody's, as a successor collateral agent. After any retiring Collateral Agent's resignation as Collateral Agent the provisions of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent under this Agreement and the other Loan Documents.

8.10 Documentation Agent. The Documentation Agent shall not have any duties or responsibilities hereunder in its capacity as such.

The Required Lenders and each Loan Party which is a party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Administrative Agent or, as the case may be, the Collateral Agent, and each Loan Party which is a party to the relevant Loan Document may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or the Agents or of the Loan Parties hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent or the Collateral Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) forgive the principal amount or extend the final scheduled date of maturity of any Loan, reduce the stated rate of any interest or fee payable hereunder (except (x) in connection with the waiver of applicability of any post-default increase in interest rates and (y) that any amendment or


44

modification of defined terms used in the financial covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (i)) or extend the scheduled date of any payment thereof, or increase the amount or extend the expiration date of any Lender's Commitment, in each case without the written consent of each Lender directly affected thereby;
(ii) eliminate or reduce the voting rights of any Lender under this Section 9.1 without the written consent of such Lender; (iii) reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Company of any of its rights and obligations under this Agreement and the other Loan Documents, release all or substantially all of the Collateral or release all or substantially all of the Subsidiary Guarantors from their obligations under the Guarantee and Collateral Agreement or the UK Charge Over Shares, as the case may be, in each case without the written consent of all Lenders; (iv) amend, modify or waive any provision of Section 9.7 without the written consent of all Lenders; and (v) amend, modify or waive any provision of

Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent, the Collateral Agent and all future holders of the Loans. In the case of any waiver, the Loan Parties, the Lenders, the Administrative Agent and the Collateral Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon.

46

any of the foregoing relating to the use of proceeds of the Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of any Group Member or any of the Properties (provided that such liability was incurred during such time as a Group Member controlled such Properties) and the reasonable fees and expenses of legal counsel in connection with claims, actions or proceedings by any Indemnitee against any Loan Party under any Loan Document (all the foregoing in this clause
(d), collectively, the "Indemnified Liabilities"), provided, that the Borrowers shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities have resulted from the gross negligence or willful misconduct of such Indemnitee. The payments by each Borrower pursuant to this Section 9.5 shall be in accordance with such Borrower's Proportionate Share. Without limiting the foregoing, and to the extent permitted by applicable law, the Company agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries to waive, all rights for contribution from any Indemnitee or any other rights of recovery from any Indemnitee with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section 9.5 shall be payable not later than 10 Business Days after written demand therefor and shall be accompanied by a statement setting forth in reasonable detail the source of such Indemnified Liability and the amount claimed thereunder. Statements payable by the Company pursuant to this Section 9.5 shall be submitted to Julian Cusack (Telephone No. 441-297-9715) (Telecopy No. 441-295-8201), at the address of the Company set forth in Section 9.2, or to such other Person or address as may be hereafter designated by the Company in a written notice to the Administrative Agent. The agreements in this Section 9.5 shall survive repayment of the Loans and all other amounts payable hereunder.

9.6 Successors and Assigns; Participations and Assignments. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by any Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.

(b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees (none of which may be a Borrower) (each, an "Assignee") all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

(A) the Company, provided that no consent of the Company shall be required for an assignment (1) to a Lender, an affiliate of a Lender or an Approved Fund (as defined below) or, (2) if an Event of Default has occurred and is continuing; and

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of any Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment.

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender, an affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender's Commitments or Loans, the amount of the Commitments or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with


47

respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Company and the Administrative Agent otherwise consent, provided that such amounts shall be aggregated in respect of each Lender and its affiliates or Approved Funds, if any;

(B) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(C) the Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire.

For the purposes of this Section 9.6, the term "Approved Fund" has the following meaning:

"Approved Fund" means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph
(b)(iv) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.12, 2.13, 2.14 and 9.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.6 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Assignee, the Assignee's completed administrative questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph
(b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)(i) Any Lender may, without the consent of any Borrower or the Administrative


48

Agent, sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it); provided that (A) such Lender's obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any agreement pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to the proviso to the second sentence of
Section 9.1 and (2) directly affects such Participant. Subject to paragraph
(c)(ii) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.12, 2.13, 2.14 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.8 as though it were a Lender, provided such Participant shall be subject to Section 9.7 as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.12 or 2.13 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Company's prior written consent. Any Participant that is a Non-U.S. Lender shall not be entitled to the benefits of Section 2.13 unless such Participant complies with
Section 2.13(d).

(d) Any Lender may at any time pledge or grant a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or grant to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or grant of a security interest; provided that no such pledge or grant of a security interest shall release such Lender from any of its obligations hereunder or substitute any such pledgee or grantee for such Lender as a party hereto and, provided, further, that nothing in this paragraph (d) shall be deemed to limit in any way the application of Section 9.6(b) to any assignment of the rights or obligations of such Lender under this Agreement resulting from a foreclosure of any such pledge or security interest.

(e) Each Borrower, upon receipt of written notice from the relevant Lender, agrees to issue Notes to any Lender requiring Notes to facilitate transactions of the type described in paragraph (d) above.

9.7 Adjustments. Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender or to the Lenders, if any Lender (a "Benefitted Lender") shall receive any payment of all or part of the Obligations owing to it (whether directly from the Borrower, indirectly from any Guarantor pursuant to the Guarantee and Collateral Agreement or from the proceeds of the exercise of any remedies with respect to the Collateral pursuant to the Guarantee and Collateral Agreement or the UK Charge Over Shares or otherwise), or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off (whether against any Borrower or any Guarantor), pursuant to events or proceedings of the nature referred to in Section 7(g), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter


49

recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

9.8 Set-off. Upon the occurrence and continuation of an Event of Default, in addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to any Borrower, any such notice being expressly waived by each Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by any Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of a Borrower, as the case may be. Each Lender agrees promptly to notify the Company and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application.

9.9 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Company and the Administrative Agent.

9.10 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

9.11 Integration. This Agreement and the other Loan Documents represent the entire agreement of the Borrowers, the Administrative Agent, the Collateral Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent, the Collateral Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents.

9.12 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

9.13 Submission To Jurisdiction; Waivers. Each Borrower, the Administrative Agent, the Collateral Agent and each Lender hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or


50

proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the Borrowers, as the case may be at its address set forth in Section 9.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

9.14 Releases of Guarantees and Liens. (a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, the Collateral Agent is hereby irrevocably authorized by each Lender (without requirement of notice to or consent of any Lender except as expressly required by Section 9.1) to take any action requested by the Company having the effect of releasing any Collateral or guarantee obligations (i) to the extent necessary to permit consummation of any transaction not prohibited by any Loan Document or that has been consented to in accordance with Section 9.1 or (ii) under the circumstances described in paragraph (b) below.

(b) At such time as the Loans and the other obligations under the Loan Documents shall have been paid in full in cash and the Commitments have been terminated, the Collateral shall cease to secure the Obligations, and, if at such time the Other Loans and the other obligations under the Loan Documents (as defined in the Other Credit Agreement) shall have been paid in full in cash and the Other Commitments have been terminated, the Collateral shall be released from the Liens created by the Security Documents, and the Security Documents and all obligations (other than those expressly stated to survive such termination) of the Administrative Agent, the Collateral Agent and each Loan Party under the Security Documents shall terminate, all without delivery of any instrument or performance of any act by any Person.

(c) At any such time as a Material Subsidiary ceases to meet the requirements set forth in the definition of Material Subsidiary for two consecutive fiscal quarters of the Company, the Company may, by giving written notice to the Collateral Agent, request a release from the Lien created by the Security Documents of any Pledged Stock issued by such Material Subsidiary, and the Collateral Agent shall (provided that no Event of Default shall have occurred and be continuing) execute all documents reasonably requested by the Company to effect such release and return any certificates representing such Pledged Stock to the Company, without recourse, representation or warranty, provided that no such releases shall be effected less than (a) 30 days following the receipt by the Lenders pursuant to Section 5.1 of the financial statements for the second of such fiscal quarters or (b) 60 days following the receipt by the Collateral Agent of the written notice requesting such release described above.

9.15 Confidentiality. Each of the Administrative Agent, the Collateral Agent and each Lender agrees to keep confidential all non-public information provided to it by any Group Member, the Administrative Agent, the Collateral Agent or any Lender pursuant to or in connection with this Agreement (the "Information"); provided that nothing herein shall prevent the Administrative Agent, the Collateral Agent or any Lender from disclosing any such Information
(a) to the Administrative Agent, the Collateral Agent, any other Lender or any affiliate thereof, (b) subject to an agreement to comply with the provisions of this Section, to any actual or prospective Transferee, (c) to its employees, directors, agents,


51

attorneys, accountants and other professional advisors or those of any of its affiliates, provided that such parties agree to comply with the provisions of this Section, (d) upon the request or demand of any Governmental Authority, provided that the Administrative Agent, the Collateral Agent or any Lender, as the case may be, requests confidential treatment of such Information to the extent permitted by law, (e) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, provided that the Administrative Agent, the Collateral Agent or any Lender, as the case may be, requests confidential treatment of such Information to the extent permitted by law, (f) if requested or required to do so in connection with any litigation or similar proceeding, provided that (1) the Administrative Agent, the Collateral Agent or any Lender, as the case may be, provides the Company with notice of such event promptly upon obtaining knowledge thereof (provided that the Administrative Agent, the Collateral Agent or any Lender, as the case may be, is not legally prohibited by law from giving such notice) so that the Company may seek a protective order or other appropriate remedy and (2) in the event that such protective order or other remedy is not obtained, the Administrative Agent, the Collateral Agent or any Lender, as the case may be, shall furnish only that portion of the Information that is legally required and shall disclose the Information in a manner reasonably designed to preserve its confidential nature, (g) that has been publicly disclosed other than as a result of (1) disclosure by the Administrative Agent, the Collateral Agent or any Lender in violation of this Agreement or (2) becoming available from a third party which to the knowledge of the Administrative Agent, the Collateral Agent or any Lender, as the case may be, is prohibited from disclosing such information pursuant to a contractual, legal or fiduciary obligation to the Company or a third party, (h) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender's investment portfolio in connection with ratings issued with respect to such Lender, or (i) in connection with the exercise of any remedy hereunder or under any other Loan Document. Notwithstanding anything herein to the contrary, any party to this Agreement (and any employee, representative, or other agent of any party to this Agreement) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure. However, any such Information relating to the tax treatment or tax structure is required to be kept confidential to the extent necessary to comply with any applicable federal or state securities laws.

9.16 WAIVERS OF JURY TRIAL. EACH BORROWER, THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

(b) If an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of its intent to exercise such rights to the relevant Grantor or Grantors, (i) the Collateral Agent shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Stock and make application thereof to the Borrower Obligations or the applicable Guarantor Obligations, as the case may be, in the order specified in

10

Subsidiaries and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Stock as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Stock upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other organizational structure of any Pledged Material Subsidiary, or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Pledged Stock, and in connection therewith, the right to deposit and deliver any and all of the Pledged Stock with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

All Proceeds received by the Collateral Agent from a Grantor who is not a Guarantor hereunder shall be held by the Collateral Agent in a Collateral Account maintained under its sole dominion and control and all proceeds received by the Collateral Agent from a Grantor who is a Guarantor hereunder shall be held by the Collateral Agent in a separate Collateral Account maintained under its sole dominion and control. All Proceeds while held by the Collateral Agent in any Collateral Account (or by such Grantor in trust for the Collateral Agent for the benefit of the Administrative Agents and the Lenders) shall continue to be held as collateral security for the Borrower Obligations or the applicable Guarantor Obligations, as the case may be, and shall not constitute payment thereof until applied as provided in Section 6.3.

6.3 Application of Proceeds.

11

Second, to the Administrative Agents, for application by them towards payment of amounts then due and owing and remaining unpaid in respect of the Borrower Obligations, pro rata among the Lenders, according to the amounts of the Borrower Obligations then due and owing and remaining unpaid to the Lenders; and

Third, any balance of such Proceeds remaining after the Borrower Obligations shall have been paid in full and the Commitments shall have terminated shall be paid over to the applicable Grantor or to whomsoever may be lawfully entitled to receive the same.

(b) At any time when an Event of Default shall have occurred and be continuing, the Collateral Agent may apply all or any part of Proceeds constituting Collateral the security interest in which was granted by a Grantor who is a Guarantor, whether or not held in any Collateral Account, and any proceeds of the guarantee set forth in Section 2, in payment of its Guarantor Obligations in the following order:

First, to pay incurred and unpaid fees and expenses of the Collateral Agent and the Administrative Agents under the Loan Documents, pro rata among them in according to the amounts thereof then due and owing;

Second, to the Administrative Agents, for application by them towards payment of amounts then due and owing and remaining unpaid in respect of the Guarantor Obligations, pro rata among the Lenders, according to the amounts of the Guarantor Obligations then due and owing and remaining unpaid to the Lenders; and

Third, any balance of such Proceeds remaining after the Guarantor Obligations shall have been paid in full and the Commitments shall have terminated shall be paid over to the applicable Grantor or to whomsoever may be lawfully entitled to receive the same.

6.4 Code and Other Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the Administrative Agents and the Lenders, may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the New York UCC or any other applicable law. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels, at any office of the Collateral Agent or any Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent, either Administrative Agent or any Lender shall have the right to the extent permitted by law, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released. The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 6.4, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent, the Administrative Agents and the Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in the order specified in Section 6.3, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law,


12

including, without limitation, Section 9-615(a)(3) of the New York UCC, need the Collateral Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against the Collateral Agent, either Administrative Agent or any Lender arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 Business Days before such sale or other disposition.

Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Stock, by reason of certain prohibitions contained in the Securities Act, applicable state securities laws or the securities laws of any applicable jurisdiction, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges that any such private sale may result in prices and other terms less favorable than if such sale were a public sale. The Lenders understand and agree that this Agreement contains no provision requiring that any Grantor cause the Pledged Stock pledged by it to be registered under the Securities Act or any other applicable securities laws in connection with a sale thereof by the Collateral Agent pursuant to an exercise of its remedies provided for herein.

6.5 Deficiency. Each Grantor which is a Borrower or a Guarantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its Borrower Obligations or the applicable Guarantor Obligations, as the case may be, and the fees and disbursements of any attorneys employed by the Collateral Agent, either Administrative Agent or any Lender to collect such deficiency.

6.6 Limitation of Rights. (a) Notwithstanding any other term or condition contained herein, the Collateral Agent recognizes that it may not exercise any of the rights or powers described herein with respect to the ownership, transfer, sale or voting of Collateral consisting of Pledged Stock of any Insurance Subsidiary, including the foreclosure upon or sale or transfer of such Collateral, unless and until the Collateral Agent (and, in the case of a sale of such Collateral, the purchaser thereof) has complied with the filing requirements of all Requirements of Law regulating the acquisition of voting securities or control of an Insurance Subsidiary, and the acquisition of such Collateral and control of the Insurance Subsidiary which is the issuer thereof by the Collateral Agent (or by the purchaser in any such sale) has been duly approved to the extent required by and in accordance with all such laws.

(b) Upon the occurrence and during the continuance of an Event of Default, any Borrowers and the Grantors (i) will take such actions as the Collateral Agent, on behalf of the Administrative Agents and the Lenders, may reasonably request in obtaining approval of the relevant insurance commission or other Governmental Authority, if required, for any action or transaction contemplated by this Agreement and (ii) in the case of any Pledged Material Subsidiary organized under the laws of Bermuda, to cause the board of directors of the Grantor of a Lien on the Capital Stock of such Pledged Material Subsidiary to approve any transfer or sale of the Pledged Stock issued thereby to the Collateral Agent (or, in the case of a sale of the Collateral, the purchaser thereof) upon obtaining any necessary approvals from each Governmental Authority required pursuant to all applicable Requirements of Law.

Section 7. THE COLLATERAL AGENT

7.1 Collateral Agent's Appointment as Attorney-in-Fact, etc. (a) Subject to the last sentence of this Section 7.1(a), each Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-


13

fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor, to do any or all of the following:

(i) in the name of such Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due with respect to any Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due with respect to any other Collateral whenever payable;

(ii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

(iii) execute, in connection with any sale provided for in
Section 6.4, any indorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; and

(iv) (1) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (2) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (3) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (4) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (5) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Collateral Agent may deem appropriate; and (6) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent's option and such Grantor's expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent's, the Administrative Agents' and the Lenders' security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this Section 7.1(a) to the contrary notwithstanding, the Collateral Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 7.1(a) unless an Event of Default shall have occurred and be continuing and, if the rights to be exercised relate to the Capital Stock of an Insurance Subsidiary, unless all necessary filings and approvals, if any, described in Section 6.6 have been made and obtained.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement to the extent permitted by applicable law.


14

(c) The expenses of the Collateral Agent incurred in connection with actions undertaken as provided in this Section 7.1, together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR Loans under either Credit Agreement, from the date of payment by the Collateral Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Collateral Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

7.2 Execution of Financing Statements. Pursuant to any applicable law, each Grantor authorizes the Collateral Agent to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral without the signature of such Grantor in such form and in such offices as the Collateral Agent determines appropriate to perfect the security interests of the Collateral Agent under this Agreement. Each Grantor hereby ratifies and authorizes the filing by the Collateral Agent of any financing statement with respect to the Collateral made prior to the date hereof.

7.3 Duty of Collateral Agent. The Collateral Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the New York UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, either Administrative Agent any Lender nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Collateral Agent, for the benefit of the Administrative Agents and the Lenders, hereunder are solely to protect the Collateral Agent's, the Administrative Agents and the Lenders' interests in the Collateral and shall not impose any duty upon the Collateral Agent, either Administrative Agent or any Lender to exercise or cause the exercise of any such powers. The Collateral Agent, the Administrative Agents and the Lenders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

7.4 Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as among the Collateral Agent, the Administrative Agents and the Lenders, be governed by the Credit Agreements and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantors, the Collateral Agent shall be conclusively presumed to be acting as agent for the Administrative Agents and the Lenders with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

Section 8. MISCELLANEOUS

8.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 9.1 of the Credit Agreements.


15

8.2 Notices. All notices, requests and demands to or upon the Collateral Agent or any Guarantor or Grantor hereunder shall be effected in the manner provided for in Section 9.2 of the Credit Agreements; provided that any such notice, request or demand to or upon any Guarantor or Grantor shall be addressed to such Guarantor or Grantor c/o the Company at the Company's notice address set forth on Schedule 9.2 of the Credit Agreements.

8.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Collateral Agent, either Administrative Agent nor any Lender shall by any act (except by a written instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, either Administrative Agent or any Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent, either Administrative Agent or any Lender of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent, either Administrative Agent or such Lender would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

8.4 Enforcement Expenses; Indemnification. (a) Each Guarantor jointly and severally agrees to pay or reimburse the Collateral Agent for all its costs and expenses incurred in collecting against such Guarantor under the guarantee contained in Section 2 or otherwise enforcing or preserving any rights under this Agreement and the other Loan Documents to which such Guarantor is a party, including, without limitation, the fees and disbursements of counsel (including the allocated fees and expenses of in-house counsel) to the Collateral Agent.

(b) Each Guarantor jointly and severally agrees to pay, and to save the Collateral Agent harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

(c) Each Guarantor jointly and severally agrees to pay, and to save the Collateral Agent harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the extent any Borrowers would be required to do so pursuant to Section 9.5 of the Credit Agreements.

(d) The agreements in this Section 8.4 shall survive repayment of the Obligations and all other amounts payable under the Credit Agreements and the other Loan Documents.

8.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Guarantor and each Grantor and shall inure to the benefit of the Collateral Agent, the Administrative Agents and the Lenders and their successors and assigns permitted pursuant to the terms of the Credit Facilities; provided that no Guarantor or Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Collateral Agent.

8.6 Set-Off. Each Guarantor hereby irrevocably authorizes the Collateral Agent, each


16

Administrative Agent and each Lender at any time and from time to time upon the occurrence and continuation of an Event of Default pursuant to Section 7(a) of the Credit Agreements, without notice to such Guarantor or Grantor or any other Guarantor, any such notice being expressly waived by each Guarantor, to set-off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by the Collateral Agent, such Administrative Agent or such Lender to or for the credit or the account of such Guarantor, or any part thereof in such amounts as the Collateral Agent, such Administrative Agent or such Lender may elect, against and on account of the obligations and liabilities of such Guarantor to the Collateral Agent, such Administrative Agent or such Lender hereunder and claims of every nature and description of the Collateral Agent, such Administrative Agent or such Lender against such Guarantor, in any currency, whether arising hereunder, under the Credit Agreement, any other Loan Document or otherwise, as the Collateral Agent, such Administrative Agent, or such Lender may elect, whether or not the Collateral Agent, either Administrative Agent or any Lender has made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. The Collateral Agent, each Administrative Agent and each Lender shall notify such Guarantor promptly of any such set-off and the application made by the Collateral Agent, such Administrative Agent or such Lender of the proceeds thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Collateral Agent, each Administrative Agent and each Lender under this Section 8.6 are in addition to other rights and remedies (including, without limitation, other rights of set-off), which the Collateral Agent, such Administrative Agent or such Lender may have. Any amounts received by the Lenders through the exercise of the rights of set-off provided for in this Section 8.6 shall be subject to the sharing requirements of Section 9.7 of the Credit Agreements to which each Guarantor hereby expressly consents.

8.7 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

8.8 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

8.9 Section Headings. The Section headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

8.10 Integration. This Agreement and the other Loan Documents represent the agreement of the Guarantors, the Grantors, the Collateral Agent, the Administrative Agents and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Collateral Agent, either Administrative Agent or any Lender relative to subject matter hereof and thereof not expressly set forth or referred to herein or in the other Loan Documents.

8.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

8.12 Submission To Jurisdiction; Waivers. The Collateral Agent, each Administrative


17

Agent, each Lender, each Guarantor and each Grantor hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) in the case of each Guarantor and each Grantor, agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Guarantor or Grantor at its address referred to in Section 8.2 or at such other address of which the Collateral Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

8.13 Acknowledgements. Each Guarantor and each Grantor hereby acknowledges that:

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents to which it is a party;

(b) neither the Collateral Agent, either Administrative Agent nor any Lender has any fiduciary relationship with or duty to any Guarantor or Grantor arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Guarantors or Grantors, on the one hand, and the Collateral Agent, the Administrative Agents and Lenders, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Guarantors and the Grantors and the Lenders.

8.14 Additional Guarantor and Grantors. Each Subsidiary of the Company that is required to become a Grantor or a Guarantor under this Agreement pursuant to Section 5.4 or Section 5.10, as the case may be, of either Credit Agreement shall become (a) a Grantor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an Assumption Agreement substantially in the form of Annex 2 hereto and/or (b) a Guarantor for all purposes of this Agreement upon execution and delivery of a Joinder substantially in the form of Annex 3 hereto.

8.15 Releases. (a) At such time as the Loans and the other Obligations shall have


18

been paid in full, the Commitments have been terminated, the Collateral shall be released from the Liens created hereby, and this Agreement and all obligations (other than those expressly stated to survive such termination) of the Collateral Agent and each Guarantor and Grantor hereunder shall terminate, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to the Grantors. Following any such termination, the Collateral Agent shall deliver to such Grantor any Collateral held by the Collateral Agent hereunder, and execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination at such Grantor's expense.

(b) If any of the Collateral shall be sold, transferred or otherwise disposed of by any Grantor in a transaction permitted by the Credit Agreements, then the Collateral Agent, at the request and sole expense of such Grantor, shall execute and deliver to such Grantor all releases or other documents reasonably necessary or desirable for the release of the Liens created hereby on such Collateral. At the request and sole expense of any Borrower, a Guarantor shall be released from its obligations hereunder in the event that all the Capital Stock of such Guarantor shall be sold, transferred or otherwise disposed of in a transaction permitted by the Credit Agreements; provided that any Borrower shall have delivered to the Collateral Agent, at least ten Business Days prior to the date of the proposed release, a written request for release identifying the relevant Guarantor and the terms of the sale or other disposition in reasonable detail, including the price thereof and any expenses in connection therewith, together with a certification by any Borrower stating that such transaction is in compliance with the Credit Agreements and the other Loan Documents.

(c) At any such time as a Pledged Material Subsidiary ceases to meet the requirements set forth in the definition of Material Subsidiary for two consecutive fiscal quarters of the Company, any Lien created hereunder on Pledged Stock issued by such Pledged Material Subsidiary shall be released and any certificates representing the Pledged Stock shall be returned in accordance with and to the extent provided in Section 9.14(c) of the Credit Agreements.

8.16 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.


IN WITNESS WHEREOF, each of the undersigned has caused this Guarantee and Collateral Agreement to be duly executed and delivered as of the date first above written.

-7-

conferred on the Administrative Agents, the Collateral Agent or any Receiver under this deed or otherwise for any of the purposes of this deed, and the Charging Company covenants with the Administrative Agents, the Collateral Agent and each Receiver to ratify and confirm all such acts or things made, done or executed by that attorney.

-8-

Charged Property.

10. STATUS, POWERS, REMOVAL AND REMUNERATION OF RECEIVER

10.1 RECEIVER AS AGENT

Each Receiver shall be the agent of the Charging Company which shall be solely responsible for his acts or defaults, and for his remuneration and expenses, and be liable on any agreements or engagements made or entered into by him.

Until the Indebtedness is paid in full, the Collateral Agent may place and keep (for such time as it shall determine) any money received pursuant to this deed or on account of the Charging Company's liability in respect of the Indebtedness in an interest bearing separate suspense account (to the credit of either the Charging Company or the Collateral Agent as the Collateral Agent shall think fit) and the Receiver may retain the same for the period which he and the Collateral Agent consider expedient without having any obligation to apply all or any part of that money in or towards discharge of the Indebtedness.

12. PROTECTION OF THIRD PARTIES

12.1 NO OBLIGATION TO ENQUIRE

No purchaser from, or other person dealing with, the Collateral Agent or any Receiver (or their agents) shall be obliged or concerned to enquire whether:

13.1 NO LIABILITY

None of the Administrative Agents, the Collateral Agent nor any Receiver shall be liable in respect of any of the Charged Property or for any loss or damage which arises out of the exercise or the attempted or purported exercise of, or the failure to exercise any of, their respective powers, unless caused by its or his gross negligence or wilful misconduct.

13.2 POSSESSION OF CHARGED PROPERTY

If any amount paid in respect of the Indebtedness is capable of being avoided or set aside, then for the purposes of this deed that amount shall not be considered to have been paid.

Any settlement or discharge between the Charging Company and the Administrative Agents or the Collateral Agent shall be conditional upon no security or payment to the Administrative Agent or Collateral Agent by the Charging Company or any other person being avoided, set aside, ordered to be refunded or reduced by virtue of any provision or enactment relating to insolvency and accordingly the Administrative Agent and the Collateral Agent, as the case may be, shall be entitled to recover from the Charging Company the value which the Administrative Agent and the Collateral Agent, as the case may be, has placed on that security or the amount of

-12-

any such payment as if that settlement or discharge had not occurred.

The Charging Company will on demand pay to the Collateral Agent all principal monies and interest and all losses incidental to any such redemption or transfer.

19. RELEASE

19.1 At such time as all the Indebtedness has been unconditionally and irrevocably discharged in full and the Lenders have no further contingent obligations to lend under or in connection with the Credit Agreements, the Collateral Agent shall at the request and cost of the Charging Company execute such documents (or procure that its nominees execute such documents) as the Charging Company may reasonably request and which may be required to discharge all the charges created by this deed and return any certificates representing the Charged Property to the Charging Company.

OUTSTANDING CLAIMS ADVANCE CLAUSE

Applicable to so-called US Situs business protected hereunder.

In respect of all loss or losses arising in respect of that business designated above, the Reinsurer agrees within 14 days, if so requested by the Reinsured, to provide by special settlement an Outstanding Claims Advance equal to its proportionate share of outstanding losses hereunder including Incurred but not Reported (IBNR) losses, by one of the following two (2) alternatives to be chosen by the Reinsured following good faith efforts to reach mutual agreement with the Reinsurer:

1. Claims to be advanced with interest to by calculated at the 3 monthly LIBOR rate for United States Dollars plus 1.50%. The three monthly LIBOR rate for each such collection shall be the rate ruling at 12:00 GMT on the date each such advance is made by the Reinsurer. Interest payments shall be made by the Reinsured to the Reinsurer 3 months after the date of the first invoice and quarterly thereafter.

2. Claims to be paid at a mutually agreed Present Value of the incurred loss including IBNR for which an Outstanding Claims Advance is requested.

Such proportionate share for any loss shall be computed as at any one time by comparing the recovery due hereunder by reason of the Reinsured's paid loss and that recovery which would be due hereunder if it were permitted for such loss to also include the value of the Reinsured's notified outstanding amounts including IBNR for that same loss. The Reinsurer's undertakings are further conditioned upon the understanding that:

1. this Agreement applies only to loss reserve deposits and not to premium reserve deposits;

2. any deposits or advances hereunder will only be established for the benefit of Reinsured's ceding companies. Any amounts appropriated from any Outstanding Claims Advance provided by or on behalf of the Reinsurer shall be deemed to have been sums paid by the Reinsurer on account of its proportion of settled losses (if any) for which the Reinsurer is properly liable under this Agreement and the amount of such payments shall be brought into account in the Accounts to the credit of Reinsurer;

3. the amount of any Outstanding Claims Advance or Letter Of Credit provided by common account Reinsurers shall be netted against any Outstanding Claims Advance amount provided hereunder.

The foregoing option may be exercised at any time in respect of each original incurred loss. In the event that the Reinsured requests an increase in an Outstanding Claims Advance, such adjustment shall only be made on the next applicable calendar quarter (being 1st January, 1st April, 1st July and 1st October).

CONFIDENTIALITY CLAUSE

The Reinsured has designated the underwriting information used to place this Agreement as confidential and proprietary information ('confidential information'). The Reinsurer agrees that the confidential information shall only be disclosed to those employees of the Reinsurer who need to know the information in connection with the evaluation of this risk, who have been

5 of 11

informed of the confidential nature of the confidential information and who have agreed not to disclose the confidential information to anyone not participating in the evaluation of the risk on behalf of The Reinsurer. The Reinsurer shall, unless disclosure is lawfully required by a competent court of jurisdiction, hold in confidence, and shall require its employees to hold in confidence, the confidential information.

The Reinsurer shall be under a continuing non-delegable duty not to disclose, directly or indirectly or permit the disclosure of directly or indirectly, the confidential information to any third person.

EXTRA-CONTRACTUAL OBLIGATIONS CLAUSE NMX 100

This Agreement shall exclude all cover in respect of Extra-Contractual Obligations howsoever arising, such Extra-Contractual Obligations being defined as any award made by a court of competent jurisdiction against an insurer or reinsurer, which award is not within the coverage granted by any insurance and/or reinsurance contract made between the parties in dispute.

Notwithstanding the foregoing, this Agreement shall extend to cover any loss arising from Claims Related Extra-Contractual Obligation:

(a) awarded against the Reinsured or

(b) incurred by the Reinsured where he has paid his share of a Claims Related Extra-Contractual Obligation awarded against one or more of his co-insurers.

It is warranted that any recovery under this Agreement in respect of Claims Related Extra-Contractual Obligations shall be for that part of any award which corresponds to the Reinsured's share of the reinsurance and/or reinsurance policy and/or contract giving rise to the award and all proportional protection effected by the Reinsured shall provide or shall be deemed to provide pro-rata coverage for such obligation.

This Agreement shall also extend to cover all loss from Extra-Contractual Obligations howsoever arising where the loss is incurred by the Reinsured as a result of his participation in any insurance or reinsurance which provides cover for such loss, it being understood and agreed that such loss results from a contractual liability incurred by the Reinsured.

A Claims Related Extra-Contractual Obligation shall be defined as the amount awarded against an insurer or Reinsurer found liable by a court of competent jurisdiction to pay damages to an insured or reinsured in respect of the conduct of a claim made under an insurance and/or reinsurance policy and/or contract, where such liability has arisen because of:

(a) the failure of the insurer or Reinsurer to agree or pay a claim within the policy limits or to provide defence against such claims as required by law or

(b) bad faith or negligence in rejecting an offer of settlement or

(c) negligence or breach of duty in the preparation of the defence or the conduct of it trial or the preparation or prosecution of any appeal and/or subrogation and/or any subsequent action resulting therefrom

6 of 11

There shall be no liability under this Agreement in respect of

(a) any assumption of liability by way of participation in any mutual scheme designed specifically to cover Extra-Contractual Obligation; or

(b) any Extra-Contractual Obligation arising from the fraud of a director, officer or employee of the Reinsured acting individually or collectively or in collusion with an individual or corporation or with any other organisation or party involved in the presentation, defence or settlement of any claim.

Any loss arising under this Agreement in respect of Claims Related Extra- Contractual Obligations shall be deemed to be a loss arising from the same event as that giving rise to the claim to which the Extra-Contractual Obligation is related; but recovery hereunder is subject to the insurance and/or reinsurance policy and/or contract which gives rise to the Extra-Contractual Obligation falling within the scope of this Agreement.

OFFSET CLAUSE

Each party hereto shall have the right to offset any balance or balances, whether on account of premium or on account of losses, due from one party to another party under this Agreement, against any balance or balances due and payable to one party from the other under this Agreement. However, in the event of the insolvency of any party hereto, offset shall only be allowed in accordance with applicable statutes and regulations.

UK JURISDICTION CLAUSE

This Agreement is governed by and is to be construed according to the Law of England. All questions or disputes arising out of or in connection with this Agreement, which cannot be decided by Mediation or Arbitration, shall be referred to an English Court and litigated solely in London.

MEDIATION CLAUSE

In the event of any dispute or difference of opinion arising out of or relating to this Agreement, including but not limited to the formation, interpretation, validity, performance or breach of this Agreement, whether such dispute arises before or after the expiration of this Agreement, the Reinsured and the Reinsurer agree that, prior to requesting Arbitration, they will submit such dispute to non-binding Mediation which will be held in London, England.

Mediation shall be initiated by the delivery of a written notice of a request for Mediation by one party to the other. Each party shall submit a list of not more than four potential mediators to the other party within thirty days of the delivery of such written notice. The two Parties shall then agree on the appointment of one Mediator from the combined lists. The Mediator shall be an active or retired officer of an insurance or reinsurance company or an Underwriter at Lloyd's, and shall be a disinterested third party to the Mediation.

The Mediator will schedule an initial Mediation session within thirty days of appointment and will be responsible for the formulation of an agenda to be distributed to the parties involved in the Mediation not less than five days before the Mediation commences.

7 of 11

Additionally, the Mediator will arrange the neutral site where the Mediation will take place and advise the parties of the time the Mediation shall commence.

The Mediator will have no power of enforcement of any decision which may be rendered nor will the Mediator have any right to the assessment of any damages, including punitive damages, to either party participating in this Mediation.

If, in the opinion of the Mediator, the parties cannot resolve the dispute or difference of opinion, the dispute shall then be submitted to binding Arbitration in accordance with the Arbitration Clause. Each party shall bear the expense of its own representatives and shall jointly and equally bear with the other party the expenses of the Mediation.

ARBITRATION CLAUSE

For any dispute not resolved by mediation such dispute or other matter in question between the Reinsured and the Reinsurer arising out of, or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute arises before or after termination of this Agreement, shall be settled by arbitration. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one party to the other within a reasonable time after the dispute has arisen.

Each party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either party refuses or neglects to appoint an arbitrator within sixty days, the other party may appoint the second arbitrator. If the two arbitrators do not agree on a third arbitrator within sixty days of their appointment, each one of the arbitrators shall nominate three individuals. Each arbitrator shall then decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. The arbitrators shall be active or retired officers of insurance or reinsurance companies or Lloyd's of London Underwriters; the arbitrators shall be disinterested parties.

The arbitration bearings shall be held in London, England, or such place as may be mutually agreed by the arbitrators. Each party shall submit its case to the arbitrators within sixty days of the selection of the third arbitrator or within such longer period as may be agreed by the arbitrators. The arbitrators shall interpret this agreement as an honourable engagement and shall not be obliged to follow judicial formalities or the rules of evidence except to the extent required by English law; they shall make their decisions according to the custom and practice of the reinsurance business. The decision, rendered by a majority of the arbitrators, shall not include awards for Extra-Contractual Obligations and shall be final and binding on both parties. Such decision shall be a condition precedent to any right of legal action arising out of the arbitrated dispute which either party may have against the other. Judgment upon the award rendered may be entered in any court having jurisdiction thereof.

Each party shall pay the fee and expenses of its own arbitrator and one half of the fee and expenses of the third arbitrator. In the event that two arbitrators are chosen by one party, as above provided, the fees and expenses of the arbitrators shall be equally divided between the two parties. All other expenses of the arbitration shall be equally divided between the parties.

8 of 11

This arbitration agreement shall be construed as a separate and independent contract between the parties hereto and arbitration hereunder shall be a condition precedent to the commencement of any action at law.

OUTSTANDING CLAIMS ADVANCE CLAUSE

Applicable to so-called US Situs business protected hereunder.

In respect of all loss or losses arising in respect of that business designated above, the Reinsurer agrees within 14 days, if so requested by the Reinsured, to provide by special settlement an Outstanding Claims Advance equal to its proportionate share of outstanding losses hereunder including Incurred but not Reported (BNR) losses, by one of the following two (2) alternatives to be chosen by the Reinsured following good faith efforts to reach mutual agreement with the Reinsurer:

1. Claims to be advanced with interest to be calculated at the 3 monthly LIBOR rate for United States Dollars plus 1.50%. The three monthly LIBOR rate for each such collection shall be the rate ruling at 12:00 GMT on the date each such advance is made by the Reinsurer. Interest payments shall be made by the Reinsured to the Reinsurer 3 months after the date of the first invoice and quarterly thereafter.

2. Claims to be paid at a mutually agreed Present Value of the incurred loss including IBNR for which an Outstanding Claims Advance is requested.

Such proportionate share for any loss shall be computed as at any one time by comparing the recovery due hereunder by reason of the Reinsured's paid loss and that recovery which would be due hereunder if it were permitted for such loss to also include the value of the Reinsured's notified outstanding amounts including IBNR for that same loss. The Reinsurer's undertakings are further conditioned upon the understanding that:

1. this Agreement applies only to loss reserve deposits and not to premium reserve deposits;

2. any deposits or advances hereunder will only be established for the benefit of Reinsured's ceding companies. Any amounts appropriated from any Outstanding Claims Advance provided by or on behalf of the Reinsurer shall be deemed to have been sums paid by the Reinsurer on account of its proportion of settled losses (if any) for which the Reinsurer is properly liable under this Agreement and the amount of such payments shall be brought into account in the Accounts to the credit of Reinsurer;

3. the amount of any Outstanding Claims Advance or Letter Of Credit provided by common account Reinsurers shall be netted against any Outstanding Claims Advance amount provided hereunder.

The foregoing option may be exercised at any time in respect of each original incurred loss. In the event that the Reinsured requests an increase in an Outstanding Claims Advance, such adjustment shall only be made on the next applicable calendar quarter (being 1st January, 1st April, 1st July and 1st October).

Page 5 of 11

CONFIDENTIALITY CLAUSE

The Reinsured has designated the underwriting information used to place this Agreement as confidential and proprietary information ("confidential information"). Reinsurers hereon agree that the confidential information shall only be disclosed to those employees of the Reinsurers who need to know the information in connection with the evaluation of this risk, who have been informed of the confidential nature of the confidential information and who have agreed not to disclose the confidential information to anyone not participating in the evaluation of the risk on behalf of Reinsurers. The Reinsurers shall, unless disclosure is lawfully required by a competent court of jurisdiction, hold in confidence, and shall require its employees to hold in confidence, the confidential information.

The Reinsurer shall be under a continuing non-delegable duty not to disclose, directly or indirectly or permit the disclosure of, directly or indirectly, the confidential information to any third person.

EXTRA-CONTRACTUAL OBLIGATIONS CLAUSE NMX 100

This Agreement shall exclude all cover in respect of Extra-Contractual Obligations howsoever arising, such Extra-Contractual Obligations being defined as any award made by a court of competent jurisdiction against an insurer or reinsurer, which award is not within the coverage granted by any insurance and/or reinsurance contract made between the parties in dispute.

Notwithstanding the foregoing, this Agreement shall extend to cover any loss arising from Claims Related Extra-Contractual Obligation:

(a) awarded against the Reinsured or

(b) incurred by the Reinsured where he has paid his share of a Claims Related Extra-Contractual Obligation awarded against one or more of his co-insurers.

It is warranted that any recovery under this Agreement in respect of Claims Related Extra-Contractual Obligations shall be for that part of any award which corresponds to the Reinsured's share of the reinsurance and/or reinsurance policy and/or contract giving rise to the award and all proportional protection effected by the Reinsured shall provide or shall be deemed to provide pro-rata coverage for such obligation.

This Agreement shall also extend to cover all loss from Extra-Contractual Obligations howsoever arising where the loss is incurred by the Reinsured as a result of his participation in any insurance reinsurance which provides cover for such loss, it being understood and agreed that such loss results from a contractual liability incurred by the Reinsured.

A Claims Related Extra-Contractual Obligation shall be defined as the amount awarded against an insurer or Reinsurer found liable by a court of competent jurisdiction to pay damages to an insured or reinsured in respect of the conduct of a claim made under an

Page 6 of 11

insurance and/or reinsurance policy and/or contract, where such liability has arisen because of:

(a) the failure of the insurer or Reinsurer to agree or pay a claim within the policy limits or to provide defense against such claims as required by law or

(b) bad faith or negligence in rejecting an offer of settlement or

(c) negligence or breach of duty in the preparation of the defense or the conduct of it trial or the preparation or prosecution of any appeal and/or subrogation and/or any subsequent action resulting therefrom

There shall be no liability under this Agreement in respect of:

(a) any assumption of liability by way of participation in any mutual scheme designed specifically to cover Extra-Contractual Obligation; or

(b) any Extra-Contractual Obligation arising from the fraud of a director, officer or employee of the Reinsured acting individually or collectively or in collusion with an individual or corporation or with any other organisation or party involved in the presentation, defense or settlement of any claim.

Any loss arising under this Agreement in respect of Claims Related Extra-Contractual Obligations shall be deemed to be a loss arising from the same event as that giving rise to the claim to which the Extra-Contractual Obligation is related; but recovery hereunder is subject to the insurance and/or reinsurance policy and/or contract which gives rise to the Extra-Contractual Obligation falling within the scope of this Agreement.

OFFSET CLAUSE

Each party hereto shall have the right to offset any balance or balances, whether on account of premium or on account of losses, due from one party to another party under this Agreement, against any balance or balances due and payable to one party from the other under this Agreement. However, in the event of the insolvency of any party hereto, offset shall only be allowed in accordance with applicable statutes and regulations.

UK JURISDICTION CLAUSE

This Agreement is governed by and is to be construed according to the Law of England. All questions or disputes arising out of or in connection with this Agreement, which cannot be decided by Mediation or Arbitration, shall be referred to an English Court and litigated solely in London.

MEDIATION CLAUSE

In the event of any dispute or difference of opinion arising out of or relating to this Agreement, including but not limited to the formation, interpretation, validity, performance or breach of this Agreement, whether such dispute arises before or after the

Page 7 of 11

expiration of this Agreement, the Reinsured and the Reinsurer agree that, prior to requesting Arbitration, they will submit such dispute to non-binding Mediation which will be held in London, England.

Mediation shall be initiated by the delivery of a written notice of a request for Mediation by one party to the other. Each party shall submit a list of not more than four potential mediators to the other party within thirty days of the delivery of such written notice. The two Parties shall then agree on the appointment of one Mediator from the combined lists. The Mediator shall be an active or retired officer of an insurance or reinsurance company or an Underwriter at Lloyd's, and shall be a disinterested third party to the Mediation.

The Mediator will schedule an initial Mediation session within thirty days of appointment and will be responsible for the formulation of an agenda to be distributed to the parties involved in the Mediation not less than five days before the Mediation commences.

Additionally, the Mediator will arrange the neutral site where the Mediation will take place and advise the parties of the time the Mediation shall commence.

The Mediator will have no power of enforcement of any decision which may be rendered nor will the Mediator have any right to the assessment of any damages, including punitive damages, to either party participating in this Mediation.

If, in the opinion of the Mediator, the parties cannot resolve the dispute or difference of opinion, the dispute shall then be submitted to binding Arbitration in accordance with the Arbitration Clause. Each party shall bear the expense of its own representatives and shall jointly and equally bear with the other party the expenses of the Mediation.

ARBITRATION CLAUSE

For any dispute not resolved by mediation such dispute or other matter in question between the Reinsured and the Reinsures arising out of or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute arises before or after termination of this Agreement, shall be settled by arbitration. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one party to the other within a reasonable time after the dispute has arisen.

Each party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either party refuses or neglects to appoint an arbitrator within sixty days, the other party may appoint the second arbitrator. If the two arbitrators do not agree on a third arbitrator within sixty days of their appointment, each one of the arbitrators shall nominate three individuals. Each arbitrator shall then decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. The arbitrators shall be active or retired officers of insurance or reinsurance companies or Lloyd's of London Underwriters; the arbitrators shall be disinterested parties.

The arbitration hearings shall be held in London, England, or such place as may be mutually agreed by the arbitrators. Each party shall submit its case to the arbitrators

Page 8 of 11

within sixty days of the selection of the third arbitrator or within such longer period as may be agreed by the arbitrators. The arbitrators shall interpret this agreement as an honourable engagement and shall not be obliged to follow judicial formalities or the rules of evidence except to the extent required by English law; they shall make their decisions according to the custom and practice of the reinsurance business. The decision, rendered by a majority of the arbitrators, shall not include awards for Extra-Contractual Obligations and shall be final and binding on both parties. Such decision shall be a condition precedent to any right of legal action arising out of the arbitrated dispute which either party may have against the other. Judgment upon the award rendered may be entered in any court having jurisdiction thereof.

Each party shall pay the fee and expenses of its own arbitrator and one half of the fee and expenses of the third arbitrator. In the event that two arbitrators are chosen by one party, as above provided, the fees and expenses of the arbitrators shall be equally divided between the two parties. All other expenses of the arbitration shall be equally divided between the parties.

This arbitration agreement shall be construed as a separate and independent contract between the parties hereto and arbitration hereunder shall be a condition precedent to the commencement of any action at law.

OUTSTANDING CLAIMS ADVANCE CLAUSE

Applicable to so-called US Situs business protected hereunder.

In respect of all loss or losses arising in respect of that business designated above, the Reinsurer agrees within 14 days, if so requested by the Reinsured, to provide by special settlement an Outstanding Claims Advance equal to its proportionate share of outstanding losses hereunder including Incurred but not Reported (IBNR) losses, by one of the following two (2) alternatives to be chosen by the Reinsured following good faith efforts to reach mutual agreement with the Reinsurer:

1. Claims to be advanced with interest to be calculated at the 3 monthly LIBOR rate for United States Dollars plus 1.50%. The three monthly LIBOR rate for each such collection shall be the rate ruling at 12:00 GMT on the date each such advance is made by the Reinsurer. Interest payments shall be made by the Reinsured to the Reinsurer 3 months after the date of the first invoice and quarterly thereafter.

2. Claims to be paid at a mutually agreed Present Value of the incurred loss including IBNR for which an Outstanding Claims Advance is requested.

Such proportionate share for any loss shall be computed as at any one time by comparing the recovery due hereunder by reason of the Reinsured's paid loss and that recovery which would be due hereunder if it were permitted for such loss to also include the value of the Reinsured's notified outstanding amounts including IBNR for that same loss. The Reinsurer's undertakings are further conditioned upon the understanding that:

1. this Agreement applies only to loss reserve deposits and not to premium reserve deposits;

2. any deposits or advances hereunder will only be established for the benefit of Reinsured's ceding companies. Any amounts appropriated from any Outstanding Claims Advance provided by or on behalf of the Reinsurer shall be deemed to have been sums paid by the Reinsurer on account of its proportion of settled losses (if any) for which the Reinsurer is properly liable under this Agreement and the amount of such payments shall be brought into account in the Accounts to the credit of Reinsurer;

3. the amount of any Outstanding Claims Advance or Letter Of Credit provided by common account Reinsurers shall be netted against any Outstanding Claims Advance amount provided hereunder.

The foregoing option may be exercised at any time in respect of each original incurred loss. In the event that the Reinsured requests an increase in an Outstanding Claims Advance, such adjustment shall only be made on the next applicable calendar quarter (being 1st January, 1st April, 1st July and 1st October).

CONFIDENTIALITY CLAUSE

The Reinsured has designated the underwriting information used to place this Agreement as confidential and proprietary information ('confidential information'). Reinsurers hereon agree that the confidential information shall only be disclosed to those employees of the Reinsurers who need to know the information

5 of 11

in connection with the evaluation of this risk, who have been informed of the confidential nature of the confidential information and who have agreed not to disclose the confidential information to anyone not participating in the evaluation of the risk on behalf of Reinsurers. The Reinsurers shall, unless disclosure is lawfully required by a competent court of jurisdiction, hold in confidence, and shall require its employees to hold in confidence, the confidential information.

The Reinsurer shall be under a continuing non-delegable duty not to disclose, directly or indirectly or permit the disclosure of directly or indirectly, the confidential information to any third person.

EXTRA-CONTRACTUAL OBLIGATIONS CLAUSE NMX 100

This Agreement shall exclude all cover in respect of Extra-Contractual Obligations howsoever arising, such Extra-Contractual Obligations being defined as any award made by a court of competent jurisdiction against an insurer or Reinsurer, which award is not within the coverage granted by any insurance and/or reinsurance contract made between the parties in dispute.

Notwithstanding the foregoing, this Agreement shall extend to cover any loss arising from Claims Related Extra-Contractual Obligation:

(a) awarded against the Reinsured or
(b) incurred by the Reinsured where he has paid his share of a Claims Related Extra-Contractual Obligation awarded against one or more of his co-insurers.

It is warranted that any recovery under this Agreement in respect of Claims Related Extra-Contractual Obligations shall be for that part of any award which corresponds to the Reinsured's share of the reinsurance and/or reinsurance policy and/or contract giving rise to the award and all-proportional protection effected by the Reinsured shall provide or shall be deemed to provide pro-rata coverage for such obligation.

This Agreement shall also extend to cover all loss from Extra-Contractual Obligations howsoever arising where the loss is incurred by the Reinsured as a result of his participation in any insurance or reinsurance which provides cover for such loss, it being understood and agreed that such loss results from a contractual liability incurred by the Reinsured.

A Claims Related Extra-Contractual Obligation shall be defined as the amount awarded against an insurer or Reinsurer found liable by a court of competent jurisdiction to pay damages to an insured or reinsured in respect of the conduct of a claim made under an insurance and/or reinsurance policy and/or contract, where such liability has arisen because of:

(a) the failure of the insurer or Reinsurer to agree or pay a claim within the policy limits or to provide defence against such claims as required by law or

(b) bad faith or negligence in rejecting an offer of settlement or

(c) negligence or breach of duty in the preparation of the defence or the conduct of its trial or the preparation or prosecution of any appeal and/or subrogation and/or any subsequent action resulting therefrom

There shall be no liability under this Agreement in respect of:

6 of 11

(a) any assumption of liability by way of participation in any mutual scheme designed specifically to cover Extra-Contractual Obligation; or

(b) any Extra-Contractual Obligation arising from the fraud of a director, officer or employee of the Reinsured acting individually or collectively or in collusion with an individual or corporation or with any other organisation or party involved in the presentation, defence or settlement of any claim.

Any loss arising under this Agreement in respect of Claims Related Extra-Contractual Obligations shall be deemed to be a loss arising from the same event as that giving rise to the claim to which the Extra-Contractual Obligation is related; but recovery hereunder is subject to the insurance and/or reinsurance policy and/or contract which gives rise to the Extra-Contractual Obligation falling within the scope of this Agreement.

OFFSET CLAUSE

Each party hereto shall have the right to offset any balance or balances, whether on account of premium or on account of losses, due from one party to another party under this Agreement, against any balance or balances due and payable to one party from the other under this Agreement. However, in the event of the insolvency of any party hereto, offset shall only be allowed in accordance with applicable statutes and regulations.

UK JURISDICTION CLAUSE

This Agreement is governed by and is to be construed according to the Law of England. All questions or disputes arising out of or in connection with this Agreement, which cannot be decided by Mediation or Arbitration, shall be referred to an English Court and litigated solely in London.

MEDIATION CLAUSE

In the event of any dispute or difference of opinion arising out of or relating to this Agreement, including but not limited to the formation, interpretation, validity, performance or breach of this Agreement, whether such dispute arises before or after the expiration of this Agreement, the Reinsured and the Reinsurer agree that, prior to requesting Arbitration, they will submit such dispute to non-binding Mediation which will be held in London, England.

Mediation shall be initiated by the delivery of a written notice of a request for Mediation by one party to the other. Each party shall submit a list of not more than four potential mediators to the other party within thirty days of the delivery of such written notice. The two Parties shall then agree on the appointment of one Mediator from the combined lists. The Mediator shall be an active or retired officer of an insurance or reinsurance company or an Underwriter at Lloyd's, and shall be a disinterested third party to the Mediation.

The Mediator will schedule an initial Mediation session within thirty days of appointment and will be responsible for the formulation of an agenda to be distributed to the parties involved in the Mediation not less than five days before the Mediation commences.

7 of 11

Additionally, the Mediator will arrange the neutral site where the Mediation will take place and advise the parties of the time the Mediation shall commence.

The Mediator will have no power of enforcement of any decision which may be rendered nor will the Mediator have any right to the assessment of any damages, including punitive damages, to either party participating in this Mediation.

If, in the opinion of the Mediator, the parties cannot resolve the dispute or difference of opinion, the dispute shall then be submitted to binding Arbitration in accordance with the Arbitration Clause. Each party shall bear the expense of its own representatives and shall jointly and equally bear with the other party the expenses of the Mediation.

ARBITRATION CLAUSE

For any dispute not resolved by mediation such dispute or other matter in question between the Reinsured and the Reinsurer arising out of, or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute arises before or after termination of this Agreement, shall be settled by arbitration. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one party to the other within a reasonable time after the dispute has arisen.

Each party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either party refuses or neglects to appoint an arbitrator within sixty days, the other party may appoint the second arbitrator. If the two arbitrators do not agree on a third arbitrator within sixty days of their appointment, each one of the arbitrators shall nominate three individuals. Each arbitrator shall then decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. The arbitrators shall be active or retired officers of insurance or reinsurance companies or Lloyd's of London Underwriters; the arbitrators shall be disinterested parties.

The arbitration hearings shall be held in London, England, or such place as may be mutually agreed by the arbitrators. Each party shall submit its case to the arbitrators within sixty days of the selection of the third arbitrator or within such longer period as may be agreed by the arbitrators. The arbitrators shall interpret this agreement as an honourable engagement and shall not be obliged to follow judicial formalities or the rules of evidence except to the extent required by English law; they shall make their decisions according to the custom and practice of the reinsurance business. The decision, rendered by a majority of the arbitrators, shall not include awards for Extra-Contractual Obligations and shall be final and binding on both parties. Such decision shall be a condition precedent to any right of legal action arising out of the arbitrated dispute which either party may have against the other. Judgement upon the award rendered may be entered in any court having jurisdiction thereof.

Each party shall pay the fee and expenses of its own arbitrator and one half of the fee and expenses of the third arbitrator. In the event that two arbitrators are chosen by one party, as above provided, the fees and expenses of the arbitrators shall be equally divided between the two parties. All other expenses of the arbitration shall be equally divided between the parties.

This arbitration agreement shall be construed as a separate and independent contract between the parties hereto and arbitration hereunder shall be a condition precedent to the commencement of any action at law.
