  Article VI  Retention and Limit
 A.
    
    The Company shall retain and be liable for the first $1,000,000 of ultimate net loss
arising out of each occurrence. The Reinsurer shall then be liable (subject to the provisions
of paragraph B below) for the amount by which such ultimate net loss exceeds the Companys
retention, but the liability of the Reinsurer shall not exceed $1,000,000 as respects any one
occurrence, nor shall it exceed an annual aggregate limit of 2.500% of net earned premium for
the contract year.
 B.
    
    Notwithstanding the provisions of paragraph A above, no claim shall be made under this
Contract during any contract year unless and until cumulative subject excess losses paid from
losses arising out of occurrences commencing during the contract year (being losses which
would be recoverable from the Reinsurer under paragraph A above were it not for the

      provisions of this paragraph) exceed an annual aggregate retention of 5.000% of net earned
premium. The Company shall retain and be liable for such annual aggregate retention in
addition to its initial loss retention stipulated in paragraph A above.
 C.
    
    As respects any loss or losses arising out of terrorist activity, the liability of the
Reinsurer shall not exceed $1,000,000 each contract year. Terrorism losses that apply to the
annual aggregate deductible will also reduce the liability of the Reinsurer as respects the
aggregate terrorism limit.
 D.
    
    The Company shall be permitted to carry quota share and excess reinsurance, recoveries under
which shall inure solely to the benefit of the Company and be entirely disregarded in applying
all of the provisions of this Contract.
 E.
    
    The Company shall purchase or be deemed to have purchased inuring excess facultative
reinsurance to limit its ultimate net loss under any one coverage, any one policy (exclusive
of loss in excess of policy limits or extra contractual obligations) to $2,000,000 each
occurrence as respects General Liability and Employers Liability business subject hereto.
 F.
    
    The Company shall be permitted to carry excess of loss reinsurance applying to Workers
Compensation risks in the State of Minnesota, recoveries under which shall inure to the
benefit of this Contract.Such coverage shall be provided through the Minnesota Workers Compensation Reinsurance
Association. It is understood that the liability of the Reinsurer for Minnesota Workers
Compensation risks is not released.In the event the Company accrues liability that is not provided by any inuring reinsurance, for
whatever reason, the Reinsurer agrees to reinsure such excess liability.
 Article VII  Definitions

    Ultimate net loss as used herein is defined as the sum or sums (including loss in excess
of policy limits, extra contractual obligations and any loss adjustment expense, as
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:
 1.
    
    Loss in excess of policy limits shall mean 90.0% 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 in excess of the Companys policy limits having been incurred 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.
 Page 8
      2.
    
    Extra contractual obligations shall mean 90.0% 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 any 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.
 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
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.Notwithstanding 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

party involved in the presentation, defense or settlement of any claim covered hereunder.
 C.
    
    Occurrence as used herein is defined as an accident or occurrence or a series of accidents
or occurrences arising out of or caused by one event, except that:
 1.
    
    As respects General Liability policies where the Companys limit of liability for
Products and Completed Operations coverages is determined on the basis of the insureds
aggregate losses during a policy period, all such losses proceeding from or traceable to
the same causative agency shall, at the Companys option, be deemed to have been caused
by one occurrence commencing at the beginning of the policy period, it being understood
and agreed that each renewal or annual anniversary date of the policy involved shall be
deemed the beginning of a new policy period;2.
    
    Each occupational or industrial disease case or cumulative trauma case contracted
by an employee of an insured shall be deemed to have been caused by a separate
occurrence, commencing on:
 a.
    
    The date of disability for which compensation is payable if the case is
compensable under the Workers Compensation Law;b.
    
    The date disability due to the disease actually began if the case is not
compensable under the Workers Compensation Law;c.
    
    The date of cessation of employment if claim is made after employment has
ceased.
 3.

resulting from occupational or industrial disease or cumulative trauma suffered by
employees of
 Page 9
      an insured for which the employer is liable, as a result of a sudden and accidental event
not exceeding 72 hours in duration, all such losses shall be considered one occurrence
and may be combined with losses classified as other than occupational or industrial
disease or cumulative trauma which arise out of the same event and the combination of
such losses shall be considered as one occurrence within the meaning hereof.
 D.
    
    Occupational or industrial disease is any abnormal condition that fulfills all of the
following conditions:
 1.
    
    It is not traceable to a definite compensable accident occurring during the

employees past or present employment.2.
    
    It has occurred from and has been aggravated by a repetitive employment related
activity.3.
    
    It has resulted in disability or death.
 F.
    
    Loss adjustment expense as used herein shall mean expenses allocable to the investigation,
defense and/or settlement of specific claims, including litigation expenses, interest on
judgments, declaratory judgment expenses or other legal expenses and costs incurred in

structured settlement, either in satisfaction of a judgment or in an out-of-court settlement
or otherwise, the cost of the annuity or the structured settlement, as the case may be, shall
be deemed part of the Companys ultimate net loss.
 Page 10
      B.
    
    The terms annuity or structured settlement shall be understood to mean any insurance
policy, lump sum payment, agreement or device of whatever nature resulting in the payment of a
lump sum by the Company in settlement of any or all future liabilities which may attach to it
as a result of an occurrence.

of the Reinsurer, it is understood that the liability of the Reinsurer is not released
thereby. In the event the Company is required to provide benefits not provided by the annuity
for whatever reason, the Reinsurer shall pay its share of any loss.
 Article IX  Claims

    Whenever a claim is reserved by the Company for an amount greater than 50.0% of its
retention hereunder and/or whenever a claim appears likely to result in a claim under this
Contract, the Company shall notify the Reinsurer. Further, the Company shall notify the
Reinsurer whenever a claim involves a fatality, major limb amputation, spinal cord damage,
brain damage, blindness or extensive burns, regardless of liability, if the policy limits or
statutory benefits applicable to the claim are greater than the Companys retention hereunder.
The Reinsurer shall have the right to participate, at its own expense, in the defense of any
claim or suit or proceeding involving this reinsurance.
 B.
    
    All claim settlements made by the Company, provided they are within the terms of this
Contract (including but not limited to ex-gratia payments), shall be binding upon the
Reinsurer, and the Reinsurer agrees to pay all amounts for which it may be liable upon receipt
of satisfactory evidence of the amount paid by the Company.

    Payment to the Company of the Companys net profit will result in a full and final
commutation of all known and unknown losses and shall constitute a complete and final release
of the Reinsurer and the Company in respect of any and all liabilities on business covered
under this Contract during the contract year commuted.

have the option to provide a full and final commutation of all known and unknown losses, which
shall constitute a complete and final release of the Reinsurer and the Company with respect to
any and all liabilities on business covered under this Contract during the contract year
commuted.
 Article XI  Special Commutation
 A.
    
    In the event a Subscribing Reinsurer meets the following conditions, the Company may
require a commutation of that portion of any excess loss hereunder represented by any
outstanding claim or claims, including any related loss adjustment expense.
 1.
    
    The Subscribing Reinsurers A.M. Bests rating has been assigned or downgraded
below A- (inclusive of Not Rated ratings) and/or Standard & Poors rating has been
assigned or downgraded below BBB+ (inclusive of Not Rated ratings); or2.
    
    The Subscribing Reinsurer has ceased assuming new and renewal property and casualty
treaty reinsurance business.
 Outstanding claim or claims shall be defined as known or unknown claims, including any billed
yet unpaid claims. However, unless otherwise mutually agreed, this paragraph shall not apply
unless the outstanding claim or claims is for an amount not less than $5,000.
 B.
    
    If the Company elects to require commutation as provided in paragraph A above, the Company
shall submit a Statement of Valuation of the outstanding claim or claims as of the last day of
the month immediately preceding the month in which the Company elects to require commutation,
as determined by the Company. Such Statement of Valuation shall include the elements
considered reasonable to establish the excess loss and shall set forth or attach the
information relied upon by the Company and the methodology employed to calculate the excess
loss. The Subscribing Reinsurer shall then pay the amount requested within 30 calendar days
of receipt of such Statement of Valuation, unless the Subscribing Reinsurer needs additional
information from the Company to assess the Companys Statement of Valuation or contests such
amount.
 C.
    
    If the Subscribing Reinsurer needs additional information from the Company to assess the
Companys Statement of Valuation or contests the amount requested, the Subscribing Reinsurer
shall so notify the Company within 15 calendar days of receipt of the Companys Statement of
Valuation. The Company shall supply any reasonably requested information to the Subscribing
Reinsurer within 15 calendar days of receipt of the notification. Within 30 calendar days of
the date of the notification or of the receipt of the information, whichever is later, the
Subscribing Reinsurer shall provide the Company with its Statement of Valuation of the
outstanding claim or claims as of the last day of the month immediately preceding the month in
which the Company elects to require commutation, as determined by the Subscribing Reinsurer.
Such Statement of Valuation shall include the elements considered reasonable to establish the
excess loss and shall set forth or attach the information relied upon by the Subscribing
Reinsurer and the methodology employed to calculate the excess loss.
 Page 12
      D.
    
    In the event the Subscribing Reinsurers Statement of Valuation of the outstanding claim or
claims is viewed as unacceptable to the Company, the Company may either abandon the
commutation effort, or may seek to settle any difference by using an independent actuary
agreed to by the parties.
 E.
    
    If the parties cannot agree on an acceptable independent actuary within 15 calendar days of
the date of the Subscribing Reinsurers Statement of Valuation, then each party shall appoint
an actuary as party arbitrators for the limited and sole purpose of selecting an independent
actuary. If the actuaries cannot agree on an acceptable independent actuary within 15
calendar days of the date of the Subscribing Reinsurers Statement of Valuation, the Company
shall supply the Subscribing Reinsurer with a list of at least three proposed independent
actuaries, and the Subscribing Reinsurer shall select the independent actuary from that list.
 F.
    
    Upon selection of the independent actuary, both parties shall present their respective
written submissions to the independent actuary. The independent actuary may, at his or her
discretion, request additional information. The independent actuary shall issue his or her
decision within 45 calendar days after the written submissions have been filed and any
additional information has been provided.
 G.
    
    The decision of the independent actuary shall be final and binding. The expense of the
independent actuary shall be equally divided between the two parties. For the purposes of
this Article, unless mutually agreed otherwise, an independent actuary shall be an actuary
who satisfies each of the following criteria:
 1.
    
    Is regularly engaged in the valuation of claims resulting from lines of business
subject to this Contract; and2.
    
    Is either a Fellow of the Casualty Actuarial Society or of the American Academy of
Actuaries; and3.
    
    Is disinterested and impartial regarding this commutation.
 H.
    
    Notwithstanding paragraph A, B and C above, in the event that the Subscribing Reinsurer no
longer meets the conditions set forth in subparagraph 1 or 2 in paragraph A above, this
commutation may continue on a mutually agreed basis.
 I.
    
    Payment by the Subscribing Reinsurer of the amount requested in accordance with paragraph B,
C or F above, shall release the Subscribing Reinsurer from all further liability for
outstanding claim or claims, known or unknown, under this Contract, which shall release the
Company from all further liability for payments of salvage or subrogation amounts, known or
unknown, to the Subscribing Reinsurer under this Contract.
 J.
    
    In the event of any conflict between this Article and any other Article of this Contract, the
terms of this Article shall control.
 K.
    
    This Article shall survive the termination of this Contract.
 Page 13

  Article XIII  Reinsurance Premium
 A.
    
    As premium for the reinsurance provided hereunder during each contract year, the Company
shall pay the Reinsurer 0.600% of its net earned premium.
 B.
    
    Within 30 days after the end of each month, the Company shall report its net earned premium
for the month. The premium due the Reinsurer, at the rate shown in paragraph A, shall be paid
by the Company with its report. In the event this Contract is terminated in accordance with

Reinsurer setting forth the premium due hereunder for the contract year, computed in
accordance with paragraph A, and any additional premium due the Reinsurer or return premium
due the Company shall be remitted promptly.
 D.
    
    Net earned premium as used herein is defined as the Companys gross earned premium
collected on the classes of business subject to this Contract, less only the earned portion of
premiums, if any, ceded by the Company for reinsurance which inures to the benefit of this
Contract and less dividends incurred.
 Article XIV  Late Payments
 A.
    
    The provisions of this Article shall not be implemented unless specifically invoked, in
writing, by one of the parties to this Contract.
 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 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
 Page 14
      2.
    
    1/365ths of the sum of 400 basis points plus the six-month United States Treasury
Bill rate as quoted in The Wall Street Journalon the first business day of the month for
which the calculation is made; times3.
    
    The 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 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 45 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 45 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 paragraph C above, 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 10 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 XVI  Access to Records (BRMA 1D)
  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.
 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  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.

    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 XXIII  Reserves and Letters of Credit
  A.
    
    As regards policies or bonds issued by the Company coming within the scope of this Contract,
the Company agrees that when it shall file with the insurance regulatory authority or set up
on its books reserves for losses covered hereunder which it shall be required by law to set
up, it will forward to the Reinsurer a statement showing the proportion of such reserves which
is applicable to the Reinsurer. The Reinsurer hereby agrees to fund such reserves in respect
of known outstanding losses that have been reported to the Reinsurer and allocated loss
adjustment expense relating thereto, losses and allocated loss adjustment expense paid by the
Company but not recovered from the Reinsurer, plus reserves for losses incurred but not
reported, as shown in the statement prepared by the Company (hereinafter referred to as
Reinsurers Obligations) by funds withheld, cash advances or a Letter of Credit. The
Reinsurer shall have the option of determining the method of funding provided it is acceptable
to the insurance regulatory authorities having
 Page 17
      jurisdiction over the Companys reserves with regards to unauthorized reinsurers; or, should
the Reinsurer be downgraded, the method of funding shall be mutually agreed.
 B.
    
    When funding by a Letter of Credit, the Reinsurer agrees to apply for and secure timely
delivery to the Company of a clean, irrevocable and unconditional Letter of Credit issued by a
bank meeting the NAIC Securities Valuation Office credit standards for issuers of Letters of
Credit and containing provisions acceptable to the insurance regulatory authorities having
jurisdiction over the Companys reserves in an amount equal to the Reinsurers proportion of
said reserves. Such Letter of Credit shall be issued for a period of not less than one year,
and shall contain an evergreen clause, which automatically extends the term for one year
from its date of expiration or any future expiration date unless 30 days (60 days where
required by insurance regulatory authorities) prior to any expiration date the issuing bank
shall notify the Company by certified or registered mail that the issuing bank elects not to
consider the Letter of Credit extended for any additional period.
 C.
    
    The Reinsurer and Company agree that the Letters of Credit provided by the Reinsurer pursuant
to the provisions of this Contract may be drawn upon at any time, notwithstanding any other
provision of this Contract, and be utilized by the Company or any successor, by operation of
law, of the Company including, without limitation, any liquidator, rehabilitator, receiver or
conservator of the Company for the following purposes, unless otherwise provided for in a
separate Trust Agreement:
 1.
    
    To reimburse the Company for the Reinsurers Obligations, the payment of which is
due under the terms of this Contract and which has not been otherwise paid;2.
    
    To make refund of any sum which is in excess of the actual amount required to pay
the Reinsurers Obligations under this Contract, if so requested by the Reinsurer;3.
    
    To fund an account with the Company for the Reinsurers Obligations. Such cash
deposit shall be held in an interest bearing account separate from the Companys other
assets, and interest thereon not in excess of the prime rate shall accrue to the benefit
of the Reinsurer;4.
    
    To pay the Reinsurers share of any other amounts the Company claims are due under
this Contract.
 In the event the amount drawn by the Company on any Letter of Credit is in excess of the actual
amount required for subparagraphs 1 or 3, or in the case of subparagraph 4, the actual amount
determined to be due, the Company shall promptly return to the Reinsurer the excess amount so
drawn. All of the foregoing shall be applied without diminution because of insolvency on the
part of the Company or the Reinsurer.
 D.
    
    The issuing bank shall have no responsibility whatsoever in connection with the propriety of
withdrawals made by the Company or the disposition of funds withdrawn, except to ensure that
withdrawals are made only upon the order of properly authorized representatives of the
Company.
 E.
    
    At annual intervals, or more frequently as agreed but never more frequently than quarterly,
the Company shall prepare a specific statement of the Reinsurers Obligations, for the sole
purpose of amending the Letter of Credit, in the following manner:
 Page 18
      1.
    
    If the statement shows that the Reinsurers Obligations exceed the balance of
credit as of the statement date, the Reinsurer shall, within 30 days after receipt of
notice of such excess, secure delivery to the Company of an amendment to the Letter of
Credit increasing the amount of credit by the amount of such difference.2.
    
    If, however, the statement shows that the Reinsurers Obligations are less than the
balance of credit as of the statement date, the Company shall, within 30 days after
receipt of written request from the Reinsurer, release such excess credit by agreeing to
secure an amendment to the Letter of Credit reducing the amount of credit available by
the amount of such excess credit.
 Article XXIV  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 Reinsurer to the
payees under such policies and in substitution for the obligations of the company to such
payees.
 Article XXV  Arbitration (BRMA 6J)
 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
 Page 19
      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, each Arbiter shall nominate three candidates within 10 days thereafter, two of
whom the other shall decline, and the decision shall be made by drawing lots.
 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 XXVI  Service of Suit (BRMA 49C)
  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.
 Page 20
      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.
