excess layer) shall be payable by the Company concurrently with payment by the Reinsurer of the requested loss for that excess layer.

Article 11 - Salvage and Subrogation

The Reinsurer shall be credited with salvage (i.e., reimbursement obtained or recovery made by the Company, less the actual cost, excluding salaries of officials and employees of the Company and sums paid to attorneys as retainer, of obtaining such reimbursement or making such recovery) on account of claims and settlements involving reinsurance hereunder. Salvage thereon shall always be used to reimburse the excess carriers in the reverse order of their priority according to their participation before being used in any way to reimburse the Company for its primary loss. The Company hereby agrees to enforce its rights to salvage or subrogation relating to any loss, a part of which loss was sustained by the Reinsurer, and to prosecute all

8

claims arising out of such rights if, in the Company’s opinion, it is economically reasonable to do so.

B. In the event any premium, loss or other payment due either party is not received by the intermediary named in the Intermediary Article (hereinafter referred to as the “Intermediary”) by the payment due date, the party to whom payment is due may, by notifying the Intermediary in writing, require the debtor party to pay, and the debtor party agrees to pay, an interest penalty on the amount past due calculated for each such payment on the last business day of each month as follows:

1.                    As respects the payment of routine deposits and premiums due the Reinsurer, the due date shall be as provided for in the applicable section of this Contract. In the event a due date is not specifically stated for a given payment, it shall be deemed due 30 business days after the date of transmittal by the Intermediary of the initial billing for each such payment.

2.                    Any claim or loss payment due the Company hereunder shall be deemed due 30 business days after the proof of loss or demand for payment is transmitted to the Reinsurer. If such loss or claim payment is not received within the 30 business days, interest will accrue on the payment or amount overdue in accordance with paragraph B above, from the date the proof of loss or demand for payment was transmitted to the Reinsurer.

3.                    As respects any payment, adjustment or return due either party not otherwise provided for in subparagraphs 1 and 2 of this paragraph, the due date shall be as provided for in the applicable section of this Contract. In the event a due date is not

10

For purposes of interest calculations only, amounts due hereunder shall be deemed paid upon receipt by the Intermediary.

D.                 Nothing herein shall be construed as limiting or prohibiting a Subscribing Reinsurer from contesting the validity of any claim, or from participating in the defense of any claim or suit, or prohibiting either party from contesting the validity of any payment or from initiating any arbitration or other proceeding in accordance with the provisions of this Contract. If the debtor party prevails in an arbitration or other proceeding, then any interest penalties due hereunder on the amount in dispute shall be null and void. If the debtor party loses in such proceeding, then the interest penalty on the amount determined to be due hereunder shall be calculated in accordance with the provisions set forth above unless otherwise determined by such proceedings. If a debtor party advances payment of any amount it is contesting, and proves to be correct in its contestation, either in whole or in part, the other party shall reimburse the debtor party for any such excess payment made plus interest on the excess amount calculated in accordance with this Article.

E.                   Interest penalties arising out of the application of this Article that are $100 or less from any party shall be waived unless there is a pattern of late payments consisting of three or more items over the course of any 12-month period.

Article 18 - Net Retained Lines (BRMA 32E)

B.                  The amount of the Reinsurer’s liability hereunder in respect of any loss or losses shall not be increased by reason of the inability of the Company to collect from any other reinsurer(s), whether specific or general, any amounts which may have become due from such reinsurer(s), whether such inability arises from the insolvency of such other reinsurer(s) or otherwise.

Article 19 - Errors and Omissions (BRMA 14F)

Inadvertent delays, errors or omissions made in connection with this Contract or any transaction hereunder shall not relieve either party from any liability which would have attached had such delay, error or omission not occurred, provided always that such error or omission is rectified as soon as possible after discovery.

Article 21 - Taxes (BRMA 50B)

B. With regard to funding in whole or in part by letters of credit, it is agreed that each letter of credit will be in a form acceptable to insurance regulatory authorities involved, will be issued for a term of at least one year and will include an “evergreen clause,” which automatically extends the term for at least one additional year at each expiration date unless written notice of non-renewal is given to the Company not less than 30 days prior to said expiration date. The Company and the Reinsurer further agree, notwithstanding anything to the contrary in this Contract, that said letters of credit may be drawn upon by the Company or its successors in interest at any time, without diminution because of the insolvency of the Company or the Reinsurer, but only for one or more of the following purposes:

1.                    To reimburse itself for the Reinsurer’s share of losses and/or loss adjustment expense paid under the terms of policies reinsured hereunder, unless paid in cash by the Reinsurer;

2.                    To reimburse itself for the Reinsurer’s share of any other amounts claimed to be due hereunder, unless paid in cash by the Reinsurer;

13

3.                    To fund a cash account in an amount equal to the Reinsurer’s share of any ceded outstanding loss and loss adjustment expense reserves (including all case reserves plus any reasonable amount estimated to be unreported from known loss occurrences) funded by means of a letter of credit which is under non-renewal notice, if said letter of credit has not been renewed or replaced by the Reinsurer 10 days prior to its expiration date;

4.                    To refund to the Reinsurer any sum in excess of the actual amount required to fund the Reinsurer’s share of the Company’s ceded outstanding loss and loss adjustment expense reserves (including all case reserves plus any reasonable amount estimated to be unreported from known loss occurrences), if so requested by the Reinsurer.

In the event the amount drawn by the Company on any letter of credit is in excess of the actual amount required for B(1) or B(3), or in the case of B(2), the actual amount determined to be due, the Company shall promptly return to the Reinsurer the excess amount so drawn.

Article 24 - Insolvency

A.                In the event of the insolvency of one or more of the reinsured companies, this reinsurance shall be payable directly to the company or to its liquidator, receiver, conservator or statutory successor on the basis of the liability of the company without diminution because of the insolvency of the company or because the liquidator, receiver, conservator or statutory successor of the company has failed to pay all or a portion of any claim. It is agreed, however, that the liquidator, receiver, conservator or statutory successor of the company shall give written notice to the Reinsurer of the pendency of a claim against the company indicating the policy or bond reinsured which claim would involve a possible liability on the part of the Reinsurer within a reasonable time after such claim is filed in the conservation or liquidation proceeding or in the receivership, and that during the pendency of such claim, the Reinsurer may investigate such claim and interpose, at its own expense, in the proceeding where such claim is to be adjudicated, any defense or defenses that it may deem available to the company or its liquidator, receiver, conservator or statutory successor. The expense thus incurred by the Reinsurer shall be chargeable, subject to the approval of the Court, against the company as part of the expense of conservation or liquidation to the extent of a pro rata share of the benefit which may accrue to the company solely as a result of the defense undertaken by the Reinsurer.

B.                  Where two or more reinsurers are involved in the same claim and a majority in interest elect to interpose defense to such claim, the expense shall be apportioned in accordance with the terms of this Contract as though such expense had been incurred by the company.

C.                  It is further understood and agreed that, in the event of the insolvency of one or more of the reinsured companies, the reinsurance under this Contract shall be payable directly by the Reinsurer to the company or to its liquidator, receiver or statutory successor, except as provided by Section 4118(a) of the New York Insurance Law or except (1) where this Contract specifically provides another payee of such reinsurance in the event of the insolvency of the company or (2) where the Reinsurer with the consent of the direct insured or insureds has assumed such policy obligations of the company as direct obligations of the

14

Reinsurer to the payees under such policies and in substitution for the obligations of the company to such payees.

Article 25 - Arbitration

A.                As a condition precedent to any right of action hereunder, in the event of any dispute or difference of opinion hereafter arising with respect to this Contract, it is hereby mutually agreed that such dispute or difference of opinion shall be submitted to arbitration. One Arbiter shall be chosen by the Company, the other by the Reinsurer, and an Umpire shall be chosen by the two Arbiters before they enter upon arbitration, all of whom shall be active or retired disinterested executive officers of insurance or reinsurance companies or Lloyd’s London Underwriters. In the event that either party should fail to choose an Arbiter within 30 days following a written request by the other party to do so, the requesting party may choose two Arbiters who shall in turn choose an Umpire before entering upon arbitration. If the two Arbiters fail to agree upon the selection of an Umpire within 30 days following their appointment, the two Arbiters shall request the American Arbitration Association to appoint the Umpire. If the American Arbitration Association fails to appoint the Umpire within 30 days after it has been requested to do so, either party may request a justice of a Court of general jurisdiction of the state in which the arbitration is to be held to appoint the Umpire.

B.                  Each party shall present its case to the Arbiters within 30 days following the date of appointment of the Umpire. The Arbiters shall consider this Contract as an honorable engagement rather than merely as a legal obligation and they are relieved of all judicial formalities and may abstain from following the strict rules of law. The decision of the Arbiters shall be final and binding on both parties; but failing to agree, they shall call in the Umpire and the decision of the majority shall be final and binding upon both parties. Judgment upon the final decision of the Arbiters may be entered in any court of competent jurisdiction.

C.                  If more than one reinsurer is involved in the same dispute, all such reinsurers shall constitute and act as one party for purposes of this Article and communications shall be made by the Company to each of the reinsurers constituting one party, provided, however, that nothing herein shall impair the rights of such reinsurers to assert several, rather than joint, defenses or claims, nor be construed as changing the liability of the reinsurers participating under the terms of this Contract from several to joint.

D.                 Each party shall bear the expense of its own Arbiter, and shall jointly and equally bear with the other the expense of the Umpire and of the arbitration. In the event that the two Arbiters are chosen by one party, as above provided, the expense of the Arbiters, the Umpire and the arbitration shall be equally divided between the two parties.

E.                   Any arbitration proceedings shall take place at a location mutually agreed upon by the parties to this Contract, but notwithstanding the location of the arbitration, all proceedings pursuant hereto shall be governed by the law of the state in which the Company has its principal office.

Article 26 - Service of Suit (BRMA 49C)

(Applicable if the Reinsurer is not domiciled in the United States of America, and/or is not authorized in any State, Territory or District of the United States where authorization is required by insurance regulatory authorities)

A.                It is agreed that in the event the Reinsurer fails to pay any amount claimed to be due hereunder, the Reinsurer, at the request of the Company, will submit to the jurisdiction of a court of competent jurisdiction within the United States. Nothing in this Article constitutes or should be understood to constitute a waiver of the Reinsurer’s rights to commence an action in any court of competent jurisdiction in the United States, to remove an action to a United States District Court, or to seek a transfer of a case to another court as permitted by the laws of the United States or of any state in the United States.

B.                  Further, pursuant to any statute of any state, territory or district of the United States which makes provision therefor, the Reinsurer hereby designates the party named in its Interests and Liabilities Agreement, or if no party is named therein, the Superintendent, Commissioner or Director of Insurance or other officer specified for that purpose in the statute, or his successor or successors in office, as its true and lawful attorney upon whom may be served any lawful process in any action, suit or proceeding instituted by or on behalf of the Company or any beneficiary hereunder arising out of this Contract.

Article 27 - Agency Agreement

If more than one reinsured company is named as a party to this Contract, the first named company shall be deemed the agent of the other reinsured companies for purposes of sending or receiving notices required by the terms and conditions of this Contract, and for purposes of remitting or receiving any monies due any party.

Article 28 - Governing Law

This Contract shall be governed by and construed in accordance with the law of the Commonwealth of Massachusetts.

Article 29 - Severability (BRMA 72E)

If any provision of this Contract shall be rendered illegal or unenforceable by the laws, regulations or public policy of any state, such provision shall be considered void in such state, but this shall not affect the validity or enforceability of any other provision of this Contract or the enforceability of such provision in any other jurisdiction.

Article 30 - Notices and Contract Execution

A. Whenever a notice, statement, report or any other written communication is required by this Contract, unless otherwise specified, such notice, statement, report or other written communication may be transmitted by certified or registered mail, nationally or

internationally recognized express delivery service, personal delivery, electronic mail, or facsimile. With the exception of notices of termination, first class mail is also acceptable.

B. The use of any of the following shall constitute a valid execution of this Contract or any amendments thereto:

1.                   Paper documents with an original ink signature;

2.                   Facsimile or electronic copies of paper documents showing an original ink signature; and/or

3.                   Electronic records with an electronic signature made via an electronic agent. For the purposes of this Contract, the terms “electronic record,” “electronic signature” and “electronic agent” shall have the meanings set forth in the Electronic Signatures in Global and National Commerce Act of 2000 or any amendments thereto.

C. This Contract may be executed in one or more counterparts, each of which, when duly executed, shall be deemed an original.

Article 31 - Intermediary

Aon Benfield Inc., or one of its affiliated corporations duly licensed as a reinsurance intermediary, is hereby recognized as the Intermediary negotiating this Contract for all business hereunder. All communications (including but not limited to notices, statements, premiums, return premiums, commissions, taxes, losses, loss adjustment expense, salvages and loss settlements) relating to this Contract will be transmitted to the Company or the Reinsurer through the Intermediary. Payments by the Company to the Intermediary will be deemed payment to the Reinsurer. Payments by the Reinsurer to the Intermediary will be deemed payment to the Company only to the extent that such payments are actually received by the Company.

In Witness Whereof, the Company by its duly authorized representative has executed this Contract as of the date specified below:

Nuclear Incident Exclusion Clause - Physical Damage - Reinsurance (U.S.A.)

1.               This Reinsurance does not cover any loss or liability accruing to the Reassured, directly or indirectly and whether as Insurer or Reinsurer, from any Pool of Insurers or Reinsurers formed for the purpose of covering Atomic or Nuclear Energy risks.

2.               Without in any way restricting the operation of paragraph (1) of this Clause, this Reinsurance does not cover any loss or liability accruing to the Reassured, directly or indirectly and whether as Insurer or Reinsurer, from any insurance against Physical Damage (including business interruption or consequential loss arising out of such Physical Damage) to:

I.                      Nuclear reactor power plants including all auxiliary property on the site, or

II.                  Any other nuclear reactor installation, including laboratories handling radioactive materials in connection with reactor installations, and “critical facilities” as such, or

III.              Installations for fabricating complete fuel elements or for processing substantial quantities of “special nuclear material,” and for reprocessing, salvaging, chemically separating, storing or disposing of “spent” nuclear fuel or waste materials, or

IV.              Installations other than those listed in paragraph (2) III above using substantial quantities of radioactive isotopes or other products of nuclear fission.

3.               Without in any way restricting the operations of paragraphs (1) and (2) hereof, this Reinsurance does not cover any loss or liability by radioactive contamination accruing to the Reassured, directly or indirectly, and whether as Insurer or Reinsurer, from any insurance on property which is on the same site as a nuclear reactor power plant or other nuclear installation and which normally would be insured therewith except that this paragraph (3) shall not operate

(a)                    where Reassured does not have knowledge of such nuclear reactor power plant or nuclear installation, or

(b)                   where said insurance contains a provision excluding coverage for damage to property caused by or resulting from radioactive contamination, however caused. However on and after 1st January 1960 this sub-paragraph (b) shall only apply provided the said radioactive contamination exclusion provision has been approved by the Governmental Authority having jurisdiction thereof.

4.               Without in any way restricting the operations of paragraphs (1), (2) and (3) hereof, this Reinsurance does not cover any loss or liability by radioactive contamination accruing to the Reassured, directly or indirectly, and whether as Insurer or Reinsurer, when such radioactive contamination is a named hazard specifically insured against.

5.               It is understood and agreed that this Clause shall not extend to risks using radioactive isotopes in any form where the nuclear exposure is not considered by the Reassured to be the primary hazard.

6.               The term “special nuclear material” shall have the meaning given it in the Atomic Energy Act of 1954 or by any law amendatory thereof.

7.      Reassured to be sole judge of what constitutes:

(a)       substantial quantities, and

(b)      the extent of installation, plant or site. Note.-Without in any way restricting the operation of paragraph (1) hereof, it is understood and agreed that

(a)                    all policies issued by the Reassured on or before 31st December 1957 shall be free from the application of the other provisions of this Clause until expiry date or 31st December 1960 whichever first occurs whereupon all the provisions of this Clause shall apply.

(b)                   with respect to any risk located in Canada policies issued by the Reassured on or before 31st December 1958 shall be free from the application of the other provisions of this Clause until expiry date or 31st December 1960 whichever first occurs whereupon all the provisions of this Clause shall apply.

Total Insured Value Exclusion Clause

It is the mutual intention of the parties to exclude risks, other than Offices, Hotels, Apartments, Hospitals, Educational Establishments and Public Utilities (except Railroad Schedules), and Builders Risks on the above classes, where at the time of cession, the Total Insured Value over all interests exceeds $250,000,000. However, the Company shall be protected hereunder, subject to the other terms and conditions of this Contract, if subsequent to cession being made, the Company becomes acquainted with the true facts of the case and discovers that the mutual intention has been inadvertently breached; on condition that the Company shall at the first opportunity, and certainly by next anniversary of the original policy, exclude the risk in question.

It is agreed that this mutual intention does not apply to Contingent Business Interruption or to interests traditionally underwritten as Inland Marine or to Stock and/or Contents written on a blanket basis except where the Company is aware that the Total Insured Value of $250,000,000 is already exceeded for buildings, machinery, equipment and direct use and occupancy at the key location.

It is understood and agreed that this Clause shall not apply hereunder where the Company writes 100% of the risk.

Terrorism Exclusion Clause

A.                Notwithstanding any provision to the contrary within this Contract or any addendum thereto, it is agreed that this Contract excludes loss, damage, cost or expense directly or indirectly caused by, contributed to by, resulting from, arising out of or in connection with any “act of terrorism,” as defined in the Terrorism Risk Insurance Act of 2002, as amended by the Terrorism Risk Insurance Extension Act of 2005, and any subsequent amendments or extensions thereof (the “Terrorism Act”), provided such “act of terrorism” has been committed by an individual or individuals acting on behalf of any foreign person or foreign interest, on primary or excess property and casualty insurance issued by the Company, regardless of any other cause or event contributing concurrently or in any sequence to the loss.

B.                  Notwithstanding the above and subject otherwise to the terms, conditions and limitations of this Contract, this Contract will pay actual loss or damage caused by any act of terrorism which does not meet the definition of “insured loss” set forth in the Terrorism Act or meets the definition of “insured loss” as set forth in the Terrorism Act, but results in loss under a policy that is not included in “property and casualty insurance” as defined in the Terrorism Act, provided, in either case, (1) such loss or damage occurs in a line of insurance otherwise covered by this Contract, and (2) in no event will this Contract provide coverage for loss, damage, cost or expense directly or indirectly caused by, contributed to by, resulting from, or arising out of or in connection with biological, chemical, radioactive or nuclear explosion, pollution, contamination and/or fire following thereon.

(Re)Insurer’s Liability Clause - LMA3333

(Re)Insurer’s liability several not joint

The liability of a (re)insurer under this contract is several and not joint with other (re)insurers party to this contract. A (re)insurer is liable only for the proportion of liability it has underwritten. A (re)insurer is not jointly liable for the proportion of liability underwritten by any other (re)insurer. Nor is a (re)insurer otherwise responsible for any liability of any other (re)insurer that may underwrite this contract.

The proportion of liability under this contract underwritten by a (re)insurer (or, in the case of a Lloyd’s syndicate, the total of the proportions underwritten by all the members of the syndicate taken together) is shown next to it’s stamp. This is subject always to the provision concerning “signing” below.

In the case of a Lloyd’s syndicate, each member of the syndicate (rather than the syndicate itself) is a (re)insurer. Each member has underwritten a proportion of the total shown for the syndicate (that total itself being the total of the proportions underwritten by all the members of the syndicate taken together). The liability of each member of the syndicate is several and not joint with other members. A member is liable only for that members proportion. A member is not jointly liable for any other member’s proportion. Nor is any member otherwise responsible for any liability of any other (re)insurer that may underwrite this contract. The business address of each member is Lloyd’s, One Lime Street, London EC3M 7HA. The identity of each member of a Lloyd’s syndicate and their respective proportion may be obtained by writing to Market Services, Lloyd’s, at the above address.

Proportion of liability

Unless there is “signing” (see below), the proportion of liability under this contract underwritten by each (re)insurer (or, in the case of a Lloyd’s syndicate, the total of the proportions underwritten by all the members of the syndicate taken together) is shown next to its stamp and is referred to as its “written line”.

Where this contract permits, written lines, or certain written lines, may be adjusted (“signed”). In that case a schedule is to be appended to this contract to show the definitive proportion of liability under this contract underwritten by each (re)insurer (or, in the case of a Lloyd’s syndicate, the total of the proportions underwritten by all the members of the syndicate taken together). A definitive proportion (or, in the case of a Lloyd’s syndicate, the total of the proportions underwritten by all the members of a Lloyd’s syndicate taken together) is referred to as a “signed line”. The signed lines shown in the schedule will prevail over the written lines unless a proven error in calculation has occurred.

Although reference is made at various points in this clause to “this contract” in the singular, where the circumstances so

require this should be read as a reference to contracts in the plural.
