The Forward Counterparty has entered into a forward stock purchase agreement, consisting of a Confirmation (which incorporates the terms of an ISDA Master Agreement) dated the date hereof, with the Company (the “Forward Purchase Contract”), pursuant to which the Company has agreed to issue, and the Forward Counterparty has agreed to purchase, pursuant to the terms of such Forward Purchase Contract, a number of Common Shares specified thereunder. The Forward Counterparty or its affiliates also propose to sell from time to time an additional 2,524,721 Common Shares (the “Additional Shares”), which the Forward Counterparty or its affiliates will sell in connection with the Forward Purchase Contract.

The registration statement, as amended to the date of this Agreement, is hereinafter referred to as the “Registration Statement,” and the prospectus included therein at the time the Registration Statement became effective, is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement dated October 25, 2005 (the “Prospectus Supplement”), relating to the Shares and

the Additional Shares, in the form first used to confirm sales of the Shares is hereinafter referred to as the “Prospectus.” If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference to the Registration Statement, the Basic Prospectus, any preliminary form of prospectus previously filed with the Commission pursuant to Rule 424 of the Securities Act or the Prospectus shall be deemed to refer to and include the documents incorporated therein by reference pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the effective date of the Registration Statement or the issue date of such preliminary prospectus or the Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the effective date of the Registration Statement or the issue date of any preliminary prospectus or the Prospectus, as the case may be, deemed to be incorporated therein by reference.

     (iv)to the best of such counsel’s knowledge, there are no United States federal or New York insurance statutes or regulations or orders that have been enacted, adopted or issued by any U.S. or New York insurance regulatory authority that are required to be described in the Registration Statement or the Prospectus that are not described as required.

     (f)The Underwriter shall have received on the Closing Date an opinion of Marc Wetherhill, corporate counsel to the Company, dated the Closing Date, and addressed to the Underwriter in form and substance reasonably satisfactory to counsel for the Underwriter, to the effect that:

     (viii)the consummation of the transactions contemplated by the Agreement (including but not limited to any actions taken pursuant to the indemnification and contribution provisions contained herein) will not, subject to Section 39A(2A) of the Companies Act, constitute unlawful financial assistance by the Company or Partner Reinsurance under Bermuda law;

     (ix)all statements made (A) in the Registration Statement and Prospectus (including the documents incorporated therein by reference) with respect to (1) the Shares and the Additional Shares (insofar as such statements relate to matters of Bermuda law), (2) the memorandum of association, bye-laws or other organizational documents of the Company or Partner Reinsurance, (3) statutes, regulations, rules, treaties and other laws of Bermuda (including, but not limited to, statements made with respect to insurance, regulatory and tax matters and to the Bermuda Insurance Act), (4) enforcement of judgments in Bermuda and (5) the statements related to Bermuda or the documents governed by Bermuda law made under the headings “Description of Our Capital Shares” and “Material Bermuda and United States Federal Income Tax Consequences” and (B) in the Registration Statement in Item 15 with respect to the Company, in each case insofar as such statements constitute summaries of documents referred to therein, fairly and accurately present the information set forth therein and such counsel’s opinion as to such matter;

14

     (x)neither the Underwriter nor any of the initial purchasers of the Shares or the Additional Shares are subject to any stamp duty, excise or similar tax imposed in Bermuda in connection with the offering, sale or purchase of the Shares or the Additional Shares;

     (xii)there are no currency exchange control laws or withholding taxes of Bermuda that would be applicable to the payment of dividends on the Shares and the Additional Shares by the Company or by Partner Reinsurance to the Company;

     (xiii)the Company, as provided in the Registration Statement, has duly and irrevocably appointed PartnerRe U.S. Corporation as its agent for the purposes described in Section 12 of this Agreement and to receive service of process in actions against it arising out of or in connection with violations of the U.S. Federal securities laws in any Federal court or state court in the United States relating to transactions covered by the Prospectus and such appointment is valid under Bermuda law;

     (xiv)under the laws of Bermuda, the submission by the Company to the non-exclusive jurisdiction of any United States Federal or New York State court sitting in the Borough of Manhattan, The City of New York, New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Shares or the Additional Shares, its waiver and agreement not to assert by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum and the appointment of PartnerRe U.S. Corporation as its authorized agent for the purposes described in Section 12 of this Agreement are valid and binding; and service of process effected in the manner set forth in Section 12 of this Agreement will be effective under the laws of Bermuda to confer personal jurisdiction over each of the Company and the Subsidiaries, assuming this to be the case under the laws of the State of New York;

     (xvi)in order to ensure the legality, validity, enforceability or admissibility in evidence of the Prospectus and this Agreement, it is not necessary that any document be filed, recorded or enrolled with any Bermuda Regulatory Authority or that any stamp duties, registration or similar tax or charge be paid in Bermuda;

15

     (xvii)a final and conclusive judgment of a New York State or a Federal Court against the Company or any Subsidiary based upon this Agreement, under which a sum of money is payable (not being a sum payable in respect of taxes or other charges of a like nature or in respect of a fine or other penalty or in respect of multiple damages as defined in the Protection of Trading Interest Act, 1981) may be the subject of enforcement proceedings in the Supreme Court of Bermuda under the common law doctrine of Obligation and by action for the debt evidenced by the foreign Court’s judgment. A final opinion as to the availability of this remedy should be sought when the facts surrounding the United States court’s judgment are known, but, on general principles such counsel would expect such proceedings to be successful provided that:

     (A) the court that gave the judgment was competent to hear the action in accordance with private international law principles as applied by the courts in Bermuda (and, as at the date hereof, we believe that a Court in Bermuda would determine that any New York State or Federal Court sitting in the City of New York is so competent); and

     (B) the judgment is not contrary to public policy in Bermuda and was not obtained by fraud or in proceedings contrary to the rules of natural justice of Bermuda. Such counsel does not believe that any provisions of this Agreement would be so contrary;

     (xviii)there are no legal or governmental proceedings of any Bermuda Regulatory Authority pending or, to the best of such counsel’s knowledge, threatened against any of the Company or Partner Reinsurance or to which any of them or any of their respective properties is subject, based solely on (i) a certificate given by a director of the Company and (ii) a search of the public records of the Company and Partner Reinsurance, maintained by the Registrar of Companies and the Registrar of the Supreme Court of Bermuda; and

     (xix)except as disclosed in the Prospectus, there are no preemptive or other rights to subscribe for or to purchase or any restriction upon the voting or transfer of, any shares of capital stock of the Company or Partner Reinsurance pursuant to the Company’s or Partner Reinsurance’s memorandum of association, certificate of incorporation, bye-laws or other organizational documents, respectively, and the issuance of the Firm Shares will not be subject to any preemptive or similar rights.

In rendering his opinion as aforesaid, such counsel may, as to matters of fact, rely upon certificates of officers of the Company and, as to matters of law, may rely upon an opinion or opinions, each dated the Closing Date, of other counsel retained by the Company as to laws of any jurisdiction other than Bermuda, provided that (i) the Underwriter is notified in advance of such counsel’s intention to rely on local counsel and each such local counsel is acceptable to the Underwriter, (ii) such reliance is expressly authorized by each opinion so relied upon and a copy of each such opinion is delivered to the Underwriter and is, in form and substance reasonably satisfactory to the Underwriter and to counsel for the Underwriter, and (iii) such counsel shall

16

state in his opinion that he believes that he and the Underwriter are justified in relying on such local counsel opinion. Such counsel may also make such assumptions, and express his opinion to be subject to such reservations, as shall be reasonably satisfactory to the Underwriter’s counsel. In his opinion, such counsel shall expressly authorize Willkie Farr & Gallagher LLP and Davis Polk & Wardwell to rely on said opinion.

     (g)The Underwriter shall have received on the Closing Date an opinion of Willkie Farr & Gallagher LLP, counsel for the Underwriter, dated the Closing Date in form and substance satisfactory to the Underwriter.

     The opinions of Davis Polk & Wardwell described in paragraph 5(d), of Stroock & Stroock & Lavan, LLP described in paragraph 5(e), and of the corporate counsel of the Company described in paragraph 5(f) above shall be rendered to the Underwriter at the request of the Company and shall so state therein.

     (h)The Underwriter shall have received, on each of the date hereof and on the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriter, from Deloitte & Touche, independent chartered accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statement and certain financial information contained in the Registration Statement and the Prospectus.

     (i)The Firm Shares shall have been approved for listing, subject only to official notice of issuance, on the New York Stock Exchange.

     (j)The “lock-up” agreements, each substantially in the form of Exhibit A hereto, between the Underwriter and certain executive officers and directors of the Company relating to sales and certain other dispositions of Common Shares or certain other securities, delivered to the Underwriter on or before the Closing Date, shall be in full force and effect on the Closing Date.

     (k)The Company shall have furnished or caused to be furnished to the Underwriter such further certificates and documents as the Underwriter shall have reasonably requested.

     6.Covenants of the Company. In further consideration of the agreements of the Underwriter and the Forward Counterparty herein contained, the Company covenants with the Underwriter and the Forward Counterparty as follows:

     (a)The Company will use its best efforts to cause any amendment to the Registration Statement, if any, if not effective on the date hereof, to become effective. Prior to the termination of the offering of the Shares and the Additional Shares, the Company will not file any amendment to the Registration Statement or supplement (including the Prospectus Supplement or any preliminary prospectus) to the Basic Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished the Underwriter a copy for the Underwriter’s review prior to filing and will not file any such proposed amendment or supplement to which the Underwriter reasonably objects. Subject to the foregoing sentence, if the Registration Statement has become or becomes effective pursuant to Rule 430A, or filing of

17

a prospectus is otherwise required under Rule 424(b), the Company will cause a prospectus, properly completed, and any supplement thereto to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Underwriter of such timely filing. The Company will promptly advise the Underwriter (1) when any amendment to the Registration Statement, if any, if not effective on the date hereof, shall have become effective, (2) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (3) when, prior to termination of the offering of the Shares and the Additional Shares, any amendment to the Registration Statement shall have been filed or become effective, (4) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Prospectus or for any additional information, (5) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (6) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares and the Additional Shares for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

     (b)If, at any time when a prospectus relating to the Shares or the Additional Shares is required to be delivered under the Securities Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, the Company promptly will notify the Underwriter of such event, and either (A) (1) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 6, an amendment or supplement which will correct such statement or omission or effect such compliance and (2) supply any supplemented Prospectus to the Underwriter in such quantities as the Underwriter may reasonably request or (B)instruct the Underwriter and the Forward Counterparty to discontinue offers and sales of the Additional Shares until such time as the Company informs the Underwriter and the Forward Counterparty that offers and sales may be resumed (such days during which offers and sales of the Additional Shares are so discontinued, “Suspension Days”) and, if the Company elects to so instruct the Underwriter and the Forward Counterparty, the Underwriter and the Forward Counterparty shall each follow such instructions; provided, however,that the aggregate number of Suspension Days during the period beginning on the Closing Date and ending on March 31, 2006 shall not exceed 30 business days.

     (c)As soon as practicable, the Company will make generally available to its security holders and to the Underwriter an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Securities Act.

18

     (d)The Company will furnish to the Underwriter and counsel for the Underwriter, without charge, conformed copies of the Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Securities Act, as many copies of the Prospectus and any supplement thereto as the Underwriter may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering.

     (e)The Company will arrange, if necessary, for the qualification of the Shares and the Additional Shares for sale under the laws of such jurisdictions as the Underwriter may designate and will maintain such qualifications in effect so long as required for the distribution of the Shares and the Additional Shares; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to material taxation or service of process in suits, other than those arising out of the offering or sale of the Shares and the Additional Shares, in any jurisdiction where it is not now so subject.

     (f)The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares and the Additional Shares.

     (g)If the sale of the Shares and the Additional Shares provided for herein is not consummated because any condition to the obligations of the Underwriter set forth in Section 5 hereof is not satisfied, because of any termination pursuant to Section 8 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriter, the Company will reimburse the Underwriter on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel to the Underwriter) that shall have been incurred by them in connection with the proposed purchase and sale of the Shares and the Additional Shares.

     (h)The Company will not, without the prior written consent of the Underwriter, offer, sell, contract to sell, pledge, or otherwise dispose of, (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any Subsidiary) directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any Common Shares or any securities convertible into, or exercisable, or exchangeable for, Common Shares, or publicly announce an intention to effect any such transaction, for a period of 45 days after the date of this Agreement; provided, however, that the Company may (x) issue and sell Common Shares pursuant to any employee stock option plan, stock ownership plan or dividend reinvestment plan of the Company in effect at the date hereof and the Company may issue Common Shares issuable upon the conversion of securities or the exercise of warrants outstanding on the date hereof or (y) issue and sell in an underwritten offering Common Shares or securities convertible into or exercisable or exchangeable for Common Shares to raise funds

19

as a result of a large loss event impacting the Company’s reinsurance or insurance portfolio if, in the good faith judgment of management, it is determined that such additional funds are necessary to maintain the Company’s existing ratings or ratings outlook.

     (i)Upon the filing by Company with the SEC of its Form 10-Q for Company’s third fiscal quarter of 2005, unless at such time all of the Additional Shares have been sold as contemplated in this Agreement, the Company shall deliver, or cause to be delivered, to the Forward Counterparty (i) a letter confirming as of such date the statements contained in the paragraph of the opinion of Davis Polk & Wardwell described in the last paragraph of Section 5(d) of this Agreement and (ii) a letter dated as of such date from Deloitte & Touche LLP of the type described in Section 5(h) of this Agreement.

     7.Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless the Underwriter and the Forward Counterparty, the directors, officers, employees and agents of the Underwriter or the Forward Counterparty and each person who controls the Underwriter or the Forward Counterparty within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Shares and the Additional Shares at the time it became effective or in any amendment thereof, in any preliminary prospectus or in the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein; provided, further, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of the Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Shares or Additional Shares, or any person controlling the Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendment or supplement thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law to have been so delivered, at or prior to the written confirmation of the sale of the Shares or the Additional Shares sold by the Underwriter to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

     (b)The Underwriter agrees to indemnify and hold harmless the Company, the Forward Counterparty, the directors, officers, employees and agents of the Company or the Forward Counterparty, each of the Company’s officers who signs the Registration Statement,

20

and each person who controls the Company or the Forward Counterparty within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriter and the Forward Counterparty, but only with reference to written information relating to the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Underwriter may otherwise have. The Company acknowledges that the statements set forth (A) in the last paragraph of the cover page regarding delivery of the Additional Shares and (B) under the heading “Underwriting,” (i) the name of the Underwriter and its participation in the sale of the Shares and the Additional Shares, (ii) the sentences related to concessions and reallowances, (iii) the sentences related to underwriting commissions, (iv) the paragraphs related to stabilization and penalty bids, (v) the paragraph relating to online offers and sales, and (vi) the sentences regarding the conduct of the offering in accordance with the rules of NASD, Inc., in any preliminary prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the Underwriter for inclusion in any preliminary prospectus or the Prospectus.

     (c)Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure materially prejudices substantial rights or defenses of the indemnifying party and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action)

21

unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

     (d)In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriter agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company, the Underwriter and the Forward Counterparty may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriter and the Forward Counterparty on the other from the offering of the Shares and the Additional Shares; provided, however, that in no case shall the Underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the Shares and the Additional Shares purchased by the Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriter severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriter on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriter shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriter on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section 7, each person who controls the Underwriter or the Forward Counterparty within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of the Underwriter or the Forward Counterparty shall have the same rights to contribution as the Underwriter, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

     8.Termination. This Agreement shall be subject to termination in the absolute discretion of the Underwriter, by notice given to the Company and the Forward Counterparty prior to delivery of and payment for the Shares, if at any time prior to such time (a) (i) trading of any securities of the Company shall have been suspended by the Commission or the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange

22

shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis, and (b) in the case of any of the events specified in clause 8(a)(i) or 8(a)(iv), such event makes it, in the sole judgment of the Underwriter, impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Prospectus (exclusive of any supplement thereto).
