	As
respects each excess layer of reinsurance coverage provided by this Contract, the Company shall retain and be liable for the first amount of ultimate net loss, shown as "Company's

	2.
	The
earned reinsurance premium for the excess layer reinstated for the term of this Contract (exclusive of reinstatement premium).

the Reinsurer for that excess layer. If the earned reinsurance premium for any excess layer for the 

3

 

term
of this Contract has not been finally determined as of the date of any such statement, the calculation of reinstatement premium due for that excess layer shall be based on the annual deposit
premium for that excess layer and shall be readjusted when the earned reinsurance premium for that excess layer for the term of this Contract has been finally determined. Any reinstatement premium
shown to be due the Reinsurer for any excess layer as reflected by any such statement (less prior payments, if any, for that excess layer) shall be payable by the Company concurrently with payment by

hereinafter defined) paid or payable by the Company in settlement of claims and in satisfaction of judgments rendered on account of such claims, after deduction of all salvage, all recoveries and all
claims on inuring insurance or reinsurance, whether collectible or not. Nothing herein shall be construed to mean that losses under this Contract are not recoverable until the Company's ultimate net
loss has been ascertained.

	B.
	"Loss
in excess of policy limits" and "extra contractual obligations" as used herein shall be defined as follows:

	"Loss
in excess of policy limits" shall mean 80.0% of any amount paid or payable by the Company in excess of its policy limits, but otherwise within the terms of its policy, such loss

negligence, fraud or bad faith in rejecting an offer of settlement or in the preparation of the defense or in the trial of an action against its insured or reinsured or in the preparation or
prosecution of an appeal consequent upon such an action.

	2.

contractual obligations" shall mean 80.0% of any punitive, exemplary, compensatory or consequential damages paid or payable by the Company, not covered by any other provision of
this Contract and which arise from the handling of any claim on business subject to this Contract, such liabilities arising because of, but not limited to, failure by the Company to settle within the
policy limits or by reason of the Company's alleged or actual negligence, fraud or bad faith in rejecting an offer of settlement or in the preparation of the defense or in the trial of an action
against its insured or reinsured or in the preparation or prosecution of an appeal consequent upon such an action. An extra contractual obligation shall be deemed, in all circumstances, to have
occurred on the same date as the loss covered or alleged to be covered under the policy. 

The
amount included in ultimate net loss for anyone loss occurrence as respects loss in excess of policy limits and extra contractual obligations shall not exceed 25.0% of the Company's indemnity loss
hereunder arising out of that loss occurrence.

anything stated herein, this Contract shall not apply to any loss in excess of policy limits or any extra contractual obligation incurred by the Company as a result of any fraudulent
and/or
criminal act by any officer or director of the Company acting individually or collectively or in collusion with any individual or corporation or any other organization or party involved in the
presentation, defense or settlement of any claim covered hereunder.

        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 claims
arising out of such rights.

Subscribing Reinsurer's share under any excess layer is terminated prior to January 1, 2008); or

	2.
	The
percentage, shown as "Premium Rate" for that excess layer in Schedule A attached hereto, of the Company's net earned premium for the term of this Contract.

four equal installments of the amount, shown as "Quarterly Deposit Premium" for that excess layer in Schedule A attached hereto, on January 1, April 1, July 1 and

layer(s) shall be due to such Subscribing Reinsurer after the effective date of termination.

	C.
	Within
60 days after the termination or expiration of this Contract, the Company shall provide a report to the Reinsurer setting forth the premium due hereunder for each excess
layer, computed in accordance with paragraph A, and any additional premium due the Reinsurer or return premium due the Company for each such excess layer shall be remitted promptly.

	
D.
	"Net
 earned premium" as used herein is defined as gross earned premium of the Company for the classes of business reinsured hereunder, less the earned portion of premiums ceded by
the Company for reinsurance which inures to the benefit of this Contract. For purposes of calculating net earned premium, 90.0% of Homeowners Multiple Peril and 80.0% of Commercial Multiple Peril

	B.
	In
the event any premium, loss or other payment due either party is not received by the intermediary named in the Intermediary Article (BRMA 23A) (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 

8

 

interest
penalty on the amount past due calculated for each such payment on the last business day of each month as follows: 

	1.
	The
number of full days which have expired since the due date or the last monthly calculation, whichever the lesser; times

	2.
	1/365ths
of the six-month United States Treasury Bill rate as quoted in The Wall Street Journal on the first business day of the month for which the calculation is made;

amount past due, including accrued interest. It is agreed that interest shall accumulate until payment of the original amount due plus interest penalties have been received by the
Intermediary.

	
C.
	The
 establishment of the due date shall, for purposes of this Article, be determined 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 specifically stated for a given payment, it shall be deemed due 30 business days following transmittal of written notification that
the provisions of this Article have been invoked. 

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 XIV—Offset (BRMA 36C)  

        The Company and the Reinsurer shall have the right to offset any balance or amounts due from one party to the other under the terms of this Contract. The party
asserting the right of offset may 

9

 

exercise
such right any time whether the balances due are on account of premiums or losses or otherwise. 

Article XV—Access to Records (BRMA 1D)  

        The Reinsurer or its designated representatives shall have access at any reasonable time to all records of the Company which pertain in any way to this
reinsurance. 

Article XVI—Net Retained Lines (BRMA 32E)  

	A.
	This
Contract applies only to that portion of any policy which the Company retains net for its own account (prior to deduction of any underlying reinsurance specifically permitted in
this Contract), and in calculating the amount of any loss hereunder and also in computing the amount or amounts in excess of which this Contract attaches, only loss or losses in respect of that
portion of any policy which the Company retains net for its own account shall be included.

	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 XVII—Liability of the Reinsurer  

	A.
	The
liability of the Reinsurer shall follow that of the Company in every case and be subject in all respects to all the general and specific stipulations, clauses, waivers and
modifications of the Company's policies and any endorsements thereon. However, in no event shall this be construed in any way to provide coverage outside the terms and conditions set forth in this
Contract.

	B.
	Nothing
herein shall in any manner create any obligations or establish any rights against the Reinsurer in favor of any third party or any persons not parties to this Contract. 

Article XVIII—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 XIX—Currency (BRMA 12A)  

	A.
	Whenever
the word "Dollars" or the "$" sign appears in this Contract, they shall be construed to mean United States Dollars and all transactions under this Contract shall be in United
States Dollars.

	B.
	Amounts
paid or received by the Company in any other currency shall be converted to United States Dollars at the rate of exchange at the date such transaction is entered on the books
of the Company. 

Article XX—Taxes (BRMA SOB)  

        In consideration of the terms under which this Contract is issued, the Company will not claim a deduction in respect of the premium hereon when making tax
returns, other than income or profits tax returns, to any state or territory of the United States of America or the District of Columbia. 

10

 

Article XXI—Federal Excise Tax  

	A.
	The
Reinsurer has agreed to allow for the purpose of paying the Federal Excise Tax the applicable percentage of the premium payable hereon (as imposed under Section 4371 of the
Internal Revenue Code) to the extent such premium is subject to the Federal Excise Tax.

	B.
	In
the event of any return of premium becoming due hereunder the Reinsurer will deduct the applicable percentage from the return premium payable hereon and the Company or its agent
should take steps to recover the tax from the United States Government. 

Article XXII—Unauthorized Reinsurers  

	A.
	If
the Reinsurer is unauthorized in any state of the United States of America or the District of Columbia, the Reinsurer agrees to fund its share of the Company's ceded United States
outstanding loss and loss adjustment expense reserves (including all case reserves plus any reasonable amount estimated to be unreported from known loss occurrences) by:

	1.
	Clean,
irrevocable and unconditional letters of credit issued and confirmed, if confirmation is required by the insurance regulatory authorities involved, by a bank or banks meeting
the NAIC Securities Valuation Office credit standards for issuers of letters of credit and acceptable to said insurance regulatory authorities; and/or

	2.
	Escrow
accounts for the benefit of the Company; and/or

	3.
	Cash
advances; 

if,
without such funding, a penalty would accrue to the Company on any financial statement it is required to file with the insurance regulatory authorities involved. The Reinsurer, at its sole option,
may fund in other than cash if its method and form of funding are acceptable to the insurance regulatory authorities involved. 

	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;

	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 

11

 

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 8(1) or 8(3), or in the case of 8(2), the actual amount determined to be due, the
Company shall promptly return to the Reinsurer the excess amount so drawn. 

Article XXIII—Insolvency  

	A.
	In
the event of the insolvency of one or both 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 both 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 Reinsurer to the payees under such policies and in substitution for the obligations of the company to such payees. 

Article XXIV—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 

12

 

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 XXV—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 XXVI—Governing Law  

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

13

 

Article XXVII—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 XXVIII—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 XXIX—Intermediary (BRMA 23A)  

        Benfield Inc. is hereby recognized as the Intermediary negotiating this Contract for all business
hereunder. All communications (including but not limited to notices, statements, premium, return premium, commissions, taxes, losses, loss adjustment expense, salvages and loss settlements) relating
thereto shall be transmitted to the Company or the Reinsurer through Benfield Inc. Payments by the Company to the Intermediary shall be deemed to constitute payment to the Reinsurer. Payments
by the Reinsurer to the Intermediary shall be deemed to constitute 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 undermentioned at:

Boston, Massachusetts, this 2nd day of January in the year 2007

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 (together the "Terrorism Act"), 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.
