	A.
	This
Agreement shall apply to losses occurring within the period commencing 12:01 a.m., Eastern Standard Time, January 01, 2007, and ending 12:01 a.m., Eastern Standard
Time, December 31, 2007.

	B.

	C.

indemnify the 

 

Company
as if the entire Loss Occurrence had occurred during the time this Agreement is in force provided such Loss Occurrence covered hereunder started before the date of termination. 

ARTICLE III.—TERRITORY  

        This Agreement applies to risks located solely in the Commonwealth of Massachusetts except that with respect to Multiple Peril Policies covered hereunder, the
territorial limits of this Agreement shall be those of the original Policies when such Policies are written to cover risks primarily located in the Commonwealth of Massachusetts. 

ARTICLE IV.—LIMIT AND RETENTION  

	A.
	As
respects one or more than one Line of Business covered under this Agreement, the Company shall retain the first $15,000,000 of Ultimate Net Loss as respects each risk. The Reinsurer
shall then be liable for the amount by which the Company IS Ultimate Net Loss exceeds the Company's retention of $15,000,000, but the liability of the Reinsurer shall never exceed $13,500,000(i.e.,
90% of $15,000,000) each risk, nor shall the Reinsurer's liability exceed $27,000,000 (i.e., 90% of $30,000,000) in all during the term of this Agreement. Notwithstanding the foregoing, as respects
the event of terrorism, Reinsurer's liability shall be further limited to $13,500,000 in all, during the term of this Agreement.

	B.
	Reinsurance
of the Company's retention, set forth above, shall not be deducted in arriving at the Company's Ultimate Net Loss herein.

	C.
	It
is warranted by the Company that the reinsurance provided under this Agreement shall attach only when two or more risks are involved in the same Loss Occurrence. The Company shall
be the sole judge of what constitutes one risk provided, however, that:

	1.
	A
risk shall never be less than all insurable values within exterior walls and under one roof regardless of fire divisions, the number of Policies involved, and whether there is a
single, multiple or unrelated named insureds involved in such risk.

	2.
	When
two or more buildings are situated at the same general location, the Company shall identify on its records at the time of acceptance by the Company, those individual buildings and
all insurable values contained therein that are considered to constitute each risk. If such identification is not made, each building and all insurable values contained therein shall be considered to
be a separate risk.

	3.
	A
risk shall be determined from the standpoint of the predominant peril and such peril shall be noted in the Company's records.

	D.
	It
is warranted by the Company that it shall retain at its own risk and not reinsured in any way, 10% of Ultimate Net Loss, each Loss Occurrence as set forth above. 

ARTICLE V.—REINSTATEMENT  

	A.
	Each
claim hereunder reduces the amount of indemnity from the time of occurrence of the loss by the sum paid, but any amount so exhausted is hereby reinstated from the time the Loss
Occurrence commences hereon.

	B.
	For
each subsequent reinstatement, the Company agrees to pay an additional premium calculated at pro rata of the annual premium hereon, being pro rata both as to the fraction of the
limit of liability of this Agreement (i.e., the fraction of $15,000,000) so reinstated and as to the fraction of unexpired annual term at the time of the Loss Occurrence. 

2

 
	C.
	Nevertheless,
the Reinsurer's liability hereunder shall never exceed $13,500,000 (i.e., 90% of $15,000,000) in respect of anyone Loss Occurrence and shall be further limited in all
during the term of the Agreement to $27,000 1000 (i. e. I 90% of $30 1000,000). 

ARTICLE VI.—ULTIMATE NET LOSS  

	A.

salvages, and claims upon other reinsurances, whether collectible or not, which inure to the benefit of the Reinsurer under this Agreement, and shall include Loss Adjustment Expenses incurred by the
Company; provided, however, that in the event of the insolvency of the Company, Ultimate Net Loss shall mean the amount of loss and Loss Adjustment Expenses for which the Company is liable, and
payment by the Reinsurer shall be made to the liquidator, receiver, conservator or statutory successor of the Company in accordance with the provisions of Article XXII Insolvency of this
Agreement.

	The
term "Ultimate Net Loss" shall include 100% of Loss In Excess of Policy Limits and 100% of Extra Contractual Obligations, as defined herein, but only as respects business covered

covered by the Policies reinsured under this Agreement, but shall exclude the salaries and expenses of Company employees, office expenses and other overhead expenses.

	D.
	All
recoveries, salvages or payments recovered or received subsequent to a loss settlement under this Agreement shall be applied as if recovered or received prior to the aforesaid
settlement and all necessary adjustments to the loss settlement shall be made by the parties hereto.

	E.
	Nothing
in this Article shall be construed to mean that losses are not recoverable hereunder until the Ultimate Net Loss of the Company has been ascertained. 

ARTICLE VII.—LOSS IN EXCESS OF POLICY LIMITS  

	A.
	"Loss
in Excess of Policy Limits" is defined as loss in excess of the limit of the original Policy, such loss in excess of the limit having been incurred because of failure by the
Company to settle within the Policy limit or by reason of 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
any action against its insured or in the preparation or prosecution of an appeal consequent upon such action.

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.

	C.
	For
the purposes of this Article, the word "loss" shall mean any amounts which the Company would have been contractually liable to pay had it not been for the limit of the original
Policy.

	D.
	With
respect to coverage provided under this Article, recoveries from any insurance or reinsurance other than this Agreement shall be deducted to arrive at the amount of the Company's
Ultimate Net Loss.

action. 

	B.
	The
date on which an Extra Contractual Obligation is incurred by the Company shall be deemed, in all circumstances, to be the date of the original accident, casualty, disaster or loss
occurrence.

	C.
	However,
coverage hereunder as respects Extra Contractual Obligations shall not apply where the loss has been incurred due to the fraud of a member of the Board of Directors or a
corporate officer 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.

	D.
	Recoveries,
collectibles or retention from any other form of insurance or reinsurance including deductibles or self-insured retention which protect the Company against
Extra Contractual Obligations, whether collectible or not, shall inure to the benefit of the Reinsurer and shall be deducted from the total amount of Extra Contractual Obligations for purposes of
determining the loss hereunder.

	E.
	If
any provision of this Article shall be rendered illegal or unenforceable by the laws, regulations or public policy of any state, such provision shall be considered void in such

"Insured Losses," and "Program Year" shall have the meanings provided in the Act.

	3.
	"Company"
shall include the Company and all affiliates.

	B.
	This
reinsurance shall not apply to any fines, civil penalties or surcharges assessed pursuant to the Act.

	C.
	To
the extent that the Company allocates Insured Losses and/or federal assistance under the Act among affiliates, claims, contracts or otherwise in any manner which impacts the
reinsurance provided hereunder, the Company shall apply a reasonable allocation method acceptable to the Reinsurer.

	D.
	To
the extent that an Insured Loss is otherwise payable hereunder, the reinsurance provided by this Agreement shall apply only to the portion of liability, loss, cost and/ or expense
retained by the Company net of any federal assistance pursuant to the Act. For each Program Year, the 

7

 

liability
of the Reinsurer for Insured Losses under this Agreement shall be reduced by the ratio that the financial assistance under the Act allocated to Policies subject to this Agreement bears to
the Company's total Insured Losses subject to this Agreement. If the Company does not make such allocation, the liability of the Reinsurer for Insured Losses in any Program Year under this Agreement
shall be reduced by the ratio that the financial assistance available to the Company under the Act for that Program Year bears to the Company's total Insured Losses for the same Program Year. 

	E.
	The
parties recognize that, for any Program Year, the Reinsurer may without waiver of the foregoing Paragraphs make payments for Insured Losses which, together with available financial
assistance under the Act and the Company retentions and/or deductibles hereunder, exceed the Company's Insured Losses. In such event, the Reinsurer's proportional share of all such excess recovery
(hereafter "Reinsurer's Excess Share") shall inure to the benefit of the Reinsurer. All excess recovery described in this Paragraph shall be allocated to the Reinsurer and the Company in proportion to
the respective liability of each for Insured Losses, net of federal assistance under the Act, salvage, subrogation and other similar recoveries, as applicable.

	F.
	In
the event of a Reinsurer's Excess Share, the Company shall:

	1.
	Promptly
pay the Reinsurer's Excess Share to the Reinsurer; or

	2.
	Upon
request of the Reinsurer at any time and at the Reinsurer's sole discretion, instead assign to the Reinsurer its rights to recover directly from the federal government any portion
of Reinsurer's Excess Share not already paid to the Reinsurer. The Company shall cooperate wi th and assist the Reinsurer, at its own expense, to the extent reasonably necessary for the Reinsurer to
exercise those rights. If the Reinsurer is unable, for any reason, to exercise any right assigned to it by the Company pursuant to this Article, the Company shall pay the Reinsurer's Excess Share to
the Reinsurer as if no assignment had taken place to the extent that the Company has not been deemed to have forfeited the right to financial assistance under the Act by virtue of the attempted
assignment.

	G.
	In
the event of an Insured Loss, the Company shall provide the Reinsurer with a monthly report detailing claim settlement activities and financial assistance under the Act.
Calculations for each Program Year shall continue to be made until the settlement of all Insured Losses covered hereunder. 

ARTICLE XIII.—REINSURANCE PREMIUM  

	A.
	The
Company shall pay to the Reinsurer a premium for the reinsurance provided under this Agreement at a rate of 1.53%. Such rate shall be applied to the Company's Subject Earned

Reinsurance Corporation shall have a 90% share in the minimum and deposit premiums set forth above.

	B.
	As
promptly as possible after the expiration of this Agreement, the Company shall render a statement to the Reinsurer showing the actual reinsurance premium due hereunder. If such
premium calculations differ from the deposit previously paid, the debtor party shall pay the outstanding balance as soon as practicable, However, in no event shall the annual adjusted premium be less
than a minimum of $1,347,502.

	C.
	The
term "Subject Earned Premium" as used herein is equal to the sum of the Net Premiums written on the business covered hereunder during the period under consideration, plus the
unearned premium reserve as respects premiums in force at the beginning of such period, less the unearned premium reserve as respects premiums in force at the end of the period, said unearned 

8

 

premium
is to be calculated on an actual daily basis or in accordance with the Company's methodology I as agreed. 

	D.
	The
term "Net Premiums Written" shall mean gross premiums written less returns, allowances and reinsurances which inure to the benefit of the Reinsurer.

	E.
	The
following percentages of the Company's premium shall be allocated to the business covered under this Agreement: 90% Homeowners
