        WORKERS' COMPENSATION AND EMPLOYERS' LIABILITY $500,000 EXCESS OF
                  $500,000 EXCESS OF LOSS REINSURANCE CONTRACT

This Contract is made and entered into by and between SEABRIGHT INSURANCE
COMPANY, Chicago, Illinois (hereinafter called the "Company") and the
Subscribing Reinsurer specifically identified in the Interests and Liabilities
Agreement attaching to and forming a part of this Contract (hereinafter called
the "Reinsurer").

                                    ARTICLE 1

BUSINESS REINSURED

This Contract is to indemnify the Company in respect of the net excess liability
as herein provided and specified which may accrue to the Company as a result of
any loss or losses under any Policies classified by the Company as Workers'
Compensation and Employers' Liability Business (including U.S. Longshore and
Harbor Workers' Compensation Act, Jones Act, Federal Employers' Liability Act,
and other Federal Acts) and Maritime Employers' Liability in force, written or
renewed during the term of this Contract, by or on behalf of the Company subject
to the terms and conditions herein contained.

                                    ARTICLE 2

RETENTION AND LIMIT

A.   The Reinsurer will be liable in respect of each and every Loss Occurrence,
     irrespective of the number and kinds of Policies involved, for the Ultimate
     Net Loss over and above an initial Ultimate Net Loss of $500,000 each and
     every Loss Occurrence, subject to a limit of liability to the Reinsurer of
     $500,000 each and every Loss Occurrence.

B.   In addition to the retention described in Paragraph A. above, the Company
     will retain that amount of aggregate excess losses (i.e., the total of
     excess losses and loss expense recoverable under Paragraph A.) in the
     amount of $1,500,000 (the annual aggregate deductible).

C.   This Contract is further subject to an aggregate limit to the Reinsurer of
     $1,500,000 as respects losses from intentional nuclear detonation,
     reaction, radiation, or radioactive contamination or any intentional
     chemical or biological release or exposure.

If a Loss Occurrence involves a Policy with a deductible or self-insured
retention of $500,000 or less, the Company will retain the first $500,000 of
Ultimate Net Loss, each Loss Occurrence. The deductible or self-insured
retention will contribute to the satisfaction of the Company's retention. The
Reinsurer will then be liable for 100% of the amount by which the Ultimate Net
Loss exceeds the Company's retention, inclusive of the deductible or
self-insured retention. However, the liability of the Reinsurer will never
exceed $500,000, each Loss Occurrence.


                                     3 of 29

<PAGE>

If a Loss Occurrence involves a Policy with a deductible or a self-insured
retention of greater than $500,000, the Company's retention will be equal to and
deemed satisfied by the amount of the deductible or self-insured retention. The
Reinsurer will then be liable for 100% of the amount by which the Ultimate Net
Loss exceeds the Company's retention, inclusive of the deductible or
self-insured retention. However, the liability of the Reinsurer will never
exceed the difference between $1,000,000 and the Company's retention, each Loss
Occurrence.

If a Loss Occurrence involves more than one Policy, at least one Policy of which
contains a deductible or self-insured retention, the amount of the Ultimate Net
Loss to which the retention and limit of this Contract apply will be calculated
as the amount of Ultimate Net Loss from each Policy after application of the
deductible or self-insured retention plus the lesser of $500,000 or the sum of
the deductibles and/or self-insured retentions for all Policies contributing to
the Loss Occurrence. The sum of the deductibles and/or self-insured retentions
for all Policies contributing to the Loss Occurrence will contribute to the
satisfaction of the Company's retention. The Reinsurer will then be liable for
100% of the amount by which the loss exceeds the Company's retention of $500,000
inclusive of the sum of the deductibles and/or self-insured retentions. However,
the liability of the Reinsurer will never exceed $500,000, each Loss Occurrence.

For purposes of this Contract, "deductibles" will mean any insurance plan,
however denominated, where the insured participates in, and is responsible for,
reimbursing the Company for losses up to a specified limit. "Self-Insured
Retentions" will mean any insurance plan, however denominated, where the Company
provides coverage in excess of a specified per claim or per occurrence amount.

For the purposes of this Contract, all deductibles or self insured retentions
will be deemed to apply on an each Occurrence basis, exclusive of Loss Expenses,
regardless of the structure of the actual deductible or self insured retention
and irrespective of aggregate limitations to the insured's liability, if any.

Any Policy with a deductible of $500,000 or greater shall be subject to special
acceptance hereunder by the Reinsurer.

The Company shall retain a minimum of $150,000 Ultimate Net Loss, each Loss
Occurrence, net and unreinsured in any manner, with the exception of deductible
or self-insured retention Policies.

In order for coverage to attach hereunder, all losses must be reported to the
Reinsurer within 120 months after the expiration of this Contract (being before
October 1, 2016).

                                    ARTICLE 3

TERM

This Contract will become effective 12:01 a.m., Local Standard Time, October 1,
2005, and will remain in full force and effect for twelve months, expiring 12:01
a.m., Local Standard Time, October 1, 2006 applying to Loss Occurrences
commencing during the term of this Contract.

Should this Contract expire while a loss subject to hourly limitations covered
hereunder involving natural disasters or occupational disease (including
cumulative trauma) is in progress, the Reinsurer shall be responsible for the
loss in progress in the same manner and to the same extent it would have been
responsible had the Contract expired the day following the conclusion of the
loss in progress.

At expiration, the Company may opt for run-off until the earlier of the
expiration or next renewal of Policies in force at expiration, but in no event
longer than 12 months, plus odd time, not to exceed 18 months in all from the
date of the expiration of this Contract. The premium applicable to the run-off
period shall be at the rate set forth in this Contract multiplied by the Gross
Net Earned Premium Income earned during each calendar quarter of the run-off
period for Policies in force as of the expiration date of this Contract. Such
premium shall be payable no later than 30 days after the end of each calendar
quarter during the run-off period.

In the event this Contract expires on a run-off basis, the Reinsurer's liability
hereunder shall continue if the Company is required by statute or regulation to
continue coverage, until the earliest date on which the Company may cancel the
Policy.

                                    ARTICLE 4

SPECIAL TERMINATION

A.   The Company may terminate the Reinsurer's share in this Contract at any
     time by giving written notice to the Reinsurer in the event any of the
     following circumstances occur:

     1.   The Reinsurer's policyholders' surplus at the inception of this
          Contract has been reduced by more than 25% of the amount of surplus 12
          months prior to that date.

     2.   The Reinsurer's policyholders' surplus at any time during the term of
          this Contract has been reduced by more than 25% of the amount of
          surplus at the date of that party's most recent financial statement
          filed with regulatory authorities and available to the public as of
          the inception of this Contract.

     3.   The Reinsurer has become merged with, acquired by or controlled by any
          other company, corporation, or individual(s) not controlling that
          party's operations previously.


                                     5 of 29

<PAGE>

     4.   A state insurance department or other legal authority has ordered the
          Reinsurer to cease writing business.

     5.   The Reinsurer has become insolvent or has been placed into liquidation
          or receivership (whether voluntary or involuntary), or proceedings
          have been instituted against the Reinsurer for the appointment of a
          receiver, liquidator, rehabilitator, conservator, or trustee in
          bankruptcy, or other agent known by whatever name, to take possession
          of its assets or control of its operations.

     6.   The Reinsurer's A.M. Best's rating has been assigned or downgraded
          below A- and/or its Standard & Poors rating has been assigned or
          downgraded below BBB+.

     7.   The Reinsurer has reinsured its entire liability under this Contract
          without the Company's prior written consent.

     8.   The Reinsurer has voluntarily ceased assuming new and renewal property
          and casualty treaty reinsurance business.

B.   In the event of such termination, the liability of the Reinsurer shall be
     terminated in accordance with the provisions of the Term Article.

C.   In the event of such termination, the Company has the option to require the
     Reinsurer to immediately provide funding of any liabilities as set forth in
     the Loss Funding Article. This paragraph does not apply to any Reinsurer to
     the extent that the Reinsurer provides funding under the Loss Funding
     Article or maintains a trust fund, approved by the regulatory authorities
     having jurisdiction over the Company's credit for reinsurance, for the
     payment of claims of the Reinsurer's U.S. ceding insurers.

D.   In the event of such termination, the Reinsurer shall receive reinsurance
     premium, including any minimum reinsurance premium stated in the Contract,
     pro rata based on the period of their participation hereon. Reinstatement
     premium, if any, shall be based on the reinsurance premium for the full
     term of this Contract that the Reinsurer would have participated on had the
     Reinsurer not been terminated.

                                    ARTICLE 5

TERRITORY

The territorial scope of this Contract will follow that of the Company's
Policies.

                                    ARTICLE 7

EXCLUSIONS

This Contract does not cover:

A.   Reinsurance assumed, except where the Policy is originally underwritten by
     the Company and assumed by the Company.

B.   Business excluded by the Nuclear Incident Exclusion Clause - Liability -
     Reinsurance - U.S.A., No. 08-31-.1.

C.   Financial Guarantee and Insolvency.

D.   War, as follows:

     As regards interests which at time of loss or damage are on shore, no
     liability shall attach hereto in respect of any loss or damage which is
     occasioned by war, invasion, hostilities, acts of foreign enemies, civil
     war, rebellion, insurrection, military or usurped power, or martial law or
     confiscation by order of any government or public authority.

     This War Exclusion shall not, however, apply to interests which at time of
     loss or damage are within the territorial limits of the United States of
     America (comprising the fifty States of the Union, the District of
     Columbia, and including bridges between the U.S.A. and Mexico provided they
     are under United States ownership), Canada, St. Pierre and Miquelon,
     provided such interests are insured under Policies containing a standard
     war or hostilities or warlike operations exclusion clause.

E.   Pools, Associations and Syndicates, except losses from Assigned Risk Plans
     or similar plans are not excluded.

F.   All liability of the Company arising by contract, operation of law or
     otherwise, from its participation or membership, whether voluntary or
     involuntary, in any insolvency fund. "Insolvency Fund" includes any
     guarantee fund, plan, pool, association, fund or other arrangement,
     howsoever denominated, established or governed, which provides for any
     assessment of or payment or assumption by the Company of part or all of any
     claim, debt, charge, fee or other obligation of an insurer, or its
     successors or assigns, which has been


                                     7 of 29

<PAGE>

     declared by any competent authority to be insolvent, or which is otherwise
     deemed unable to meet any claim, debt, charge, fee or other obligation in
     whole or in part.

                                    ARTICLE 8

PREMIUM

A.   The Company will pay the Reinsurer a deposit premium of $4,650,000 for the
     term of this Contract, to be paid in the amount of $1,162,500 on the first
     day of each calendar quarter.

B.   Within 60 days following the expiration of this Contract, the Company will
     calculate a premium at a rate of 2.35% multiplied by the Company's Gross
     Net Earned Premium for this Contract. Should the premium so calculated
     exceed the deposit premium paid in accordance with Paragraph A. above, the
     Company will immediately pay the Reinsurer the difference. Should the
     premium so calculated be less than the deposit premium, the Reinsurer will
     immediately pay the Company the difference subject to a minimum premium of
     $3,720,000.

                                    ARTICLE 9

CONTINGENT PROFIT COMMISSION

Any time within twenty-four months from the expiration of this Contract, the
Company may exercise the option to commute this Contract as respects any and all
losses covered under this Contract.

Upon such commutation, the Reinsurer hereon agrees to pay a contingent profit
commission to the Company equal to 35% of the profits made under this Contract.

For the purposes of this Contract, profits shall mean:

A.   All reinsurance premiums paid by the Company to the Reinsurer; less,

B.   Reinsurance loss and loss expenses paid by the Reinsurer and received by
     the Company; less,

C.   A Reinsurer's expense factor equal to 25% of reinsurance premium paid.

The Contingent Profit Commission will be paid simultaneously with commutation,
thus constituting a complete and final release of the Reinsurer in respect of
any and all losses covered under this Contract.

Should this Contract expire on a run-off basis, wherein the Reinsurer is liable
for losses occurring after the date of expiration, then such run-off period will
be considered as part of the


                                     8 of 29

<PAGE>

Contract period for purposes of the Contingent Profit Commission, and the
calculation date will be extended to not later than 36 months following the
expiration date of this Contract.

                                   ARTICLE 10

REINSTATEMENTS

Loss payments under this Contract will reduce the limit of coverage afforded by
the amounts paid, but the limit of coverage will be reinstated from the time of
the occurrence of the loss without payment of additional premium. Nevertheless,
the Reinsurer's liability hereunder will never exceed $500,000 in respect of any
one Loss Occurrence and, subject to the limit in respect of any one Loss
Occurrence, will be further limited to $10,000,000 during the term of this
Contract by reason of any and all claims arising hereunder.

                                   ARTICLE 11

REPORTS

Within 60 days following the expiration of this Contract, the Company will
furnish the Reinsurer with the following information:

A.   Gross Net Earned Premium of the Company for the term of this Contract.

B.   Any other information which the Reinsurer may require to prepare its Annual
     Statement which is reasonably available to the Company.

                                   ARTICLE 12

DEFINITIONS

A.   The term "Ultimate Net Loss" as used in this Contract will mean the actual
     loss paid by the Company or for which the Company becomes liable to pay,
     such loss to include 90% of any Extra Contractual Obligation award (and
     expense) as defined in the Extra Contractual Obligations Article, 90% of
     any Loss in Excess of Policy Limits award as defined in the Loss In Excess
     Of Policy Limits Article, expenses of litigation and interest,
     claim-specific declaratory judgment expenses, and all other loss expense of
     the Company including, but not limited to, subrogation, salvage, and
     recovery expenses (office expenses and salaries of officials and employees
     not classified as loss adjusters are not chargeable as expenses for
     purposes of this paragraph), but salvages and all recoveries, including
     recoveries under all insurances or reinsurances which inure to the benefit
     of this Contract (whether recovered or not), will be first deducted from
     such loss to arrive at the amount of liability attaching hereunder.


                                    9 of 29

<PAGE>

     All salvages, recoveries or payments recovered or received subsequent to
     loss settlement hereunder will be applied as if recovered or received prior
     to the aforesaid settlement, and all necessary adjustments will be made by
     the parties hereto.

     For purposes of this definition, the phrase "becomes liable to pay" will
     mean the existence of a judgment which the Company does not intend to
     appeal, or a release has been obtained by the Company, or the Company has
     accepted a proof of loss.

     The phrase "claim-specific declaratory judgment expense" as used in this
     Contract will mean all expenses incurred by the Company in connection with
     declaratory judgment actions that are brought to determine the Company's
     defense and/or indemnification obligations and that are allocable to
     specific Policies and claims subject to this Contract. Claim specific
     declaratory judgment expense will be deemed to have been fully incurred by
     the Company on the date of the actual or alleged loss under the Policy
     giving rise to the action.

     Whenever the Company is required, or elects, to purchase an annuity, or to
     negotiate a structured settlement, either in satisfaction of a judgment, or
     in an out-of-court settlement, or otherwise, the sum of:

     1.   the cost of the annuity or the structured settlement, as the case may
          be; and,

     2.   the amount of any expense or interest recoverable from the Reinsurer,
          in accordance with the first paragraph of this definition,

     will, subject to the other provisions of the Loss Occurrence definition, be
     deemed the Company's Ultimate Net Loss; however, the cost of any annuity
     may be included only if the issuer of the annuity has, at the time of the
     purchase of such annuity, a rating of B+ or better assigned by A. M. Best
     Co. Inc., or has been approved by the Reinsurer herein.

     The terms "annuity" or "structured settlement" will 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 all future liabilities which may attach to it as a result of a Loss
     Occurrence.

     In the event the Company purchases an annuity which inures in whole or in
     part to the benefit 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 will pay its proportional share of any loss.

     Errors and Omissions Insurance which may now or in the future be carried by
     the Company will inure to the benefit of this Contract, and any recoveries
     therefrom will first be deducted in arriving at the Ultimate Net Loss
     hereunder.

     Nothing in this clause will be construed to mean that losses are not
     recoverable hereunder until the Company's Ultimate Net Loss has been
     ascertained.


                                    10 of 29

<PAGE>

B.   The term "Loss Occurrence" as used in this Contract will mean any one
     disaster or casualty or accident or loss or series of disasters or
     casualties or accidents or losses arising out of or caused by one event,
     except that:

     1.   a.   With respect to an occupational disease or other disease or
               cumulative trauma suffered by an employee, and for which an
               employer is liable, such occupational disease or other disease or
               cumulative trauma will be deemed a separate Loss Occurrence. The
               date of loss will be the date when compensable disability begins
               and at no other date.

          b.   If the Company shall sustain more than one loss arising from an
               occupational or other disease or cumulative trauma from one
               specific kind or class, suffered by more than one employee of the
               same employer, the Company will aggregate into the same Loss
               Occurrence all of the occupational or other disease or cumulative
               trauma losses on an each employer, claims made basis (as respects
               claims made to the Company within this Contract period). The date
               of loss for each Loss Occurrence will be the date the first claim
               is made to the Company.

               Additional employee claims attributable to the same Loss
               Occurrence will be included only if reported to the Reinsurer on
               or before 36 months following the date of loss. However, in the
               event a claim is presented in accordance with this section, the
               Reinsurer will not be liable for any additional employee claims
               in subsequent Contract periods for the same disease/employer.

               Occupational or other disease or cumulative trauma coverage is
               afforded hereunder only to claims made under the Company's first
               Policy written for an insured or to Policies written 36 months
               prior to the inception of this Contract, whichever is less.

          c.   The terms "occupational or other disease" and "cumulative trauma"
               as used in this Contract will be as defined by applicable state
               statutes, regulations or Federal Law.

          d.   The term "one specific kind or class" as used in this Contract
               will be defined as each chemical, physical or biological factor
               or condition actively causing a disease or injury.

     2.   Multiple "Acts of Terrorism" which occur within a 96-hour period and
          which have been determined by the Director of the Federal Bureau of
          Investigation (or the designee thereof) and/or the Director of the
          Department of Homeland Security (or the designee thereof) or other
          federal agency to have been carried out in concert or to have a
          related purpose or common leadership shall be considered to be one
          Loss Occurrence for the purposes of this Contract. In the absence of
          such determination by the Director of the Federal Bureau of
          Investigation (or the designee thereof) and/or the Director of the
          Department of Homeland Security (or the designee thereof) or


                                    11 of 29

<PAGE>

          other federal agency, the Company shall have the option of aggregating
          all such Acts of Terrorism which occur within a 96 hour period as one
          Loss Occurrence, regardless of their location. The beginning of the 96
          hour period shall be determined by the Company. However, should the
          Director of the Federal Bureau of Investigation (or the designee
          thereof) and/or the Director of the Department of Homeland Security
          (or the designee thereof) or other federal agency determine that such
          Acts of Terrorism have not been carried out in concert or do not have
          a related purpose or common leadership, then such Acts of Terrorism
          shall be considered separate Loss Occurrences for the purpose of this
          Contract.

C.   The term "Gross Net Earned Premium" as used in this Contract will mean the
     Gross Earned Premium of the Company's Policies reinsured hereunder, after
     adjustments for applicable rating bureau experience debits or credits,
     schedule or other underwriting credits or debits, Compensating Balance Plan
     credits, and premium discount; however, prior to dividends, deductible
     credits, self-insured retention credits for excess Policies over
     self-insured retentions, and any premium adjustments for loss sensitive
     Policies, less returned premium for cancellation and reductions, and less
     premium for reinsurance that inures to the benefit of this Contract.

D.   The term "Policy" as used in this Contract will mean any binder, policy, or
     contract of insurance or reinsurance issued, accepted or held covered
     provisionally or otherwise, by or on behalf of the Company.

E.   The term "Act of Terrorism" will be defined as:

     1.   A violent act or an act that is dangerous to:

          a.   Human life; or

          b.   Property; or

          c.   Infrastructure;

     2.   That has been committed by an individual or individuals as part of an
          effort to coerce or put in fear the civilian population, or affect the
          conduct of any Government by coercion.

     The definition of "Act of Terrorism" also includes loss, damage, cost, or
     expense directly or indirectly caused by, contributed to by, resulting
     from, or arising out of or in connection with any action in controlling,
     preventing, suppressing, retaliating against, or responding to any "Act of
     Terrorism," set forth above.

     This Contract will 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 intentional nuclear detonation,
     reaction, radiation, or radioactive contamination or any


                                    12 of 29

<PAGE>

     intentional chemical or biological release or exposure, subject to Section
     B. of the Retention and Limit Article.

                                   ARTICLE 13

NET RETAINED LINES

This Contract applies only to that portion of any insurances or reinsurances
covered by this Contract which the Company retains net for its own account, and
in calculating the amount of any loss hereunder and also in computing the amount
in excess of which this Contract attaches, only loss or losses in respect of
that portion of any insurances or reinsurances which the Company retains net for
its own account will be included, it being understood and agreed that the amount
of the Reinsurer's liability hereunder in respect of any loss or losses will not
be increased by reason of the inability of the Company to collect from any other
reinsurers, whether specific or general, any amounts which may have become due
from them whether such inability arises from the insolvency of such other
reinsurers or otherwise. It is also understood that the Company may carry Quota
Share reinsurance and underlying Excess of Loss reinsurance on its net retained
liability, recoveries from which will be disregarded for purposes of this
Contract.

The Company is granted permission to purchase facultative reinsurance for an
amount in excess of its net retained liability, recoveries from which will inure
to the benefit of the Reinsurer hereon.

                                   ARTICLE 14

EXTRA CONTRACTUAL OBLIGATIONS

This Contract will protect the Company, subject to the Reinsurer's limit of
liability appearing in the Retention and Limit Article of this Contract, where
the loss includes any Extra Contractual Obligations as provided for in the
definition of Ultimate Net Loss. "Extra Contractual Obligations" are defined as
those liabilities not covered under any other provision of this Contract and
which arise from handling of any claim on business covered hereunder, such
liabilities arising because of, but not limited to, the following: 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.

The date on which any Extra Contractual Obligation is incurred by the Company
will be deemed, in all circumstances, to be the date of the original Loss
Occurrence.

However, this Article will 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


                                    13 of 29

<PAGE>

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.

                                   ARTICLE 15

LOSS IN EXCESS OF POLICY LIMITS

In the event the Ultimate Net Loss includes an amount in excess of the Company's
Policy limit, the amount of such loss, as provided for in the definition of
Ultimate Net Loss, in excess of the Company's Policy limit will be added to the
amount of the Company's Policy limit, and the sum thereof will be considered as
one Loss Occurrence, subject to the Reinsurer's limit of liability for one Loss
Occurrence appearing in the Retention and Limit Article of this Contract.
Coverage under this paragraph extends only to loss that would have been covered
had the limit of liability of the insured's Policy been adequate.

"Loss in Excess of Policy Limits" is defined as loss in excess of the Company's
original Policy, such loss in excess of the original Policy having been incurred
because of, but not limited to, failure by it 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 reinsured or in the preparation or prosecution of
an appeal consequent upon such action.

However, coverage under this Contract for Loss in Excess of Policy Limits will
not apply where such loss in excess of the original Policy limits has been
incurred due to fraud by a member of the Board of Directors or of a corporate
officer of the Company acting individually or collectively or in collusion with
any other organization or party involved in the presentation, defense or
settlement of any claim covered under this Contract.

                                   ARTICLE 16

LEGALITY

Should the law of a political entity having jurisdiction over a party to this
Contract be in conflict with a portion or portions of this Contract such portion
or portions will be amended to the extent necessary to conform with the law, and
the balance of this Contract will remain unaltered and binding between the
parties.

                                   ARTICLE 17

LOSS FUNDING

This Article is only applicable to those Reinsurers who cannot qualify for
credit by the State having jurisdiction over the Company's loss reserves.

As regards Policies issued by the Company coming within the scope of this
Contract, the Company agrees that when it shall file with the insurance
department or set up on its books reserves for losses covered hereunder on
Policies subject to this Contract, which it shall be required to set up by law
it will forward to the Reinsurer a statement showing the proportion of such loss
reserves which is applicable to them.

The Reinsurer hereby agrees that it will apply for and secure delivery to the
Company of a clean, irrevocable and unconditional Letter of Credit issued by a
bank chosen by the Reinsurer and acceptable to the appropriate insurance
authorities, in an amount equal to the Reinsurer's proportion of the loss
reserves in respect of known outstanding losses that have been reported to the
Reinsurer and allocated loss expenses relating thereto, and Incurred But Not
Reported loss and loss expense as shown in the statement prepared by the
Company.

The Letter of Credit shall be "Evergreen" and shall be issued for a period of
not less than one year, and shall be automatically extended for one year from
its date of expiration or any future expiration date unless thirty (30) days
prior to any expiration date, the bank shall notify the Company by certified or
registered mail that it elects not to consider the Letter of Credit extended for
any additional period.

The Company, or its successors in interest, undertakes to use and apply any
amounts which it may draw upon such Credit pursuant to the terms of the Contract
under which the Letter of Credit is held, and for the following purposes only:

A.   To pay the Reinsurer's share or to reimburse the Company for the
     Reinsurer's share of any liability for loss reinsured by this Contract, the
     payment of which has been agreed by the Reinsurer and which has not
     otherwise been paid.

B.   To make refund of any sum that is in excess of the actual amount required
     to pay the Reinsurer's share of any liability reinsured by this Contract.

C.   In the event of expiration of the Letter of Credit as provided for above,
     to establish deposit of the Reinsurer's share of known and reported
     outstanding losses and allocated expenses relating thereto, and Incurred
     But Not Reported loss and loss expense under this Contract. Such cash
     deposit shall be held in an interest bearing account separate from the
     Company's other assets, and interest thereon shall accrue to the benefit of
     the Reinsurer. It is understood and agreed that this procedure will be
     implemented only in exceptional circumstances and that, if it is
     implemented, the Company will ensure that a rate of interest


                                    15 of 29

<PAGE>

     is obtained for the Reinsurer on such a deposit account that is at least
     equal to the rate which would be paid by Citibank N.A. in New York, and
     further that the Company will account to the Reinsurer on an annual basis
     for all interest accruing on the cash deposit account for the benefit of
     the Reinsurer.

The bank chosen for the issuance of the Letter of Credit 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.

At annual intervals, or more frequently as agreed but never more frequently than
semiannually, the Company shall prepare a specific statement, for the sole
purpose of amending the Letter of Credit, of the Reinsurer's share of known and
reported outstanding losses and allocated expenses relating thereto, and
Incurred But Not Reported loss and loss expense on Policies subject to this
Contract. If the statement shows that the Reinsurer's share of such losses and
allocated loss expenses, exceeds the balance of credit as of the statement date,
the Reinsurer shall, within thirty (30) days after receipt of notice of such
excess, secure delivery to the Company of an amendment of the Letter of Credit
increasing the amount of credit by the amount of such difference. If, however,
the statement shows that the Reinsurer's share of known and reported outstanding
losses plus allocated loss expenses, and Incurred But Not Reported loss and loss
expense relating thereto is less than the balance of credit as of the statement
date, the Company shall, within thirty (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.

NOTE:--Wherever used herein the term "State" shall be understood to mean the
state, province or Federal authority having jurisdiction over the Company's loss
reserves.

                                   ARTICLE 18

CALIFORNIA SB 2093 COMPLIANCE

Any Reinsurer that has gained admission to transact Workers Compensation
reinsurance business in the State of California, or that is reinsuring the
injury, disablement, or death portions of Policies of Workers Compensation
insurance in the State of California under the class of disability insurance,
shall comply with all applicable provisions of California Insurance Code
Sections 11690-11703, revised. In the event of a delinquency proceeding,
receivership or insolvency of the Company, the Insurance Commissioner of the
State of California (the "Commissioner") shall have the right to draw on any
sums from the Reinsurer's deposit that are necessary for the Commissioner to pay
those reinsured claims and obligations, or to ensure their payment by the
California Insurance Guarantee Association, deemed by the Commissioner due under
this Contract, upon failure of the Reinsurer for any reason to make payments
under this Contract. The Commissioner shall give 30 days' notice prior to
drawing upon these funds of an intent to do


                                    16 of 29

<PAGE>

so. Notwithstanding the Commissioner's right to draw on these funds, the
Reinsurer shall otherwise retain its right to determine the validity of those
claims and obligations and to contest their payment under this Contract. Prior
to a Reinsurer's deposit being drawn upon, in whole or in part, the Insurance
Department of the State of California (the "Department") shall provide the
Reinsurer with an explanation of procedures that the Reinsurer may use to
explain to the Department why the use of the Reinsurer's deposit may not be
appropriate under this Contract.

                                   ARTICLE 19

DELAYS, ERRORS OR OMISSIONS

Any inadvertent delay, omission or error will not be held to relieve either
party hereto from any liability which would attach to it hereunder if such
delay, omission or error had not been made, providing such delay, omission or
error is rectified upon discovery. Nevertheless, this Article shall not apply
with respect to loss reports rendered to the Reinsurer beyond the period
required to afford coverage in accordance with the Retention and Limit Article.

                                   ARTICLE 20

ENTIRE AGREEMENT

This Contract constitutes the entire agreement between the parties with respect
to the business reinsured hereunder, and there are no understandings between the
parties other than as expressed in this Contract. Any change or modification to
this Contract will be made by written amendment to this Contract and signed by
the parties hereto.

                                   ARTICLE 21

ACCESS TO RECORDS

The Reinsurer or its duly accredited representatives will have access to the
books and records in the possession of the Company on matters reasonably
relating to this Contract at all reasonable times for the purpose of obtaining
information concerning this Contract or the subject matter hereof.

                                   ARTICLE 22

INSOLVENCY

In the event of the insolvency of the Company, reinsurance under this Contract
shall be payable by the Reinsurer on the basis of the liability of the Company
under Policy or Policies reinsured without diminution because of the insolvency
of the Company, to the Company or to its


                                    17 of 29

<PAGE>

liquidator, receiver or statutory successor, except as provided by Section
4118(a) of the New York Insurance Law or except when the Contract specifically
provides another payee of such reinsurance in the event of the insolvency of the
Company or when 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.

It is agreed, however, that the liquidator or receiver or statutory successor of
the insolvent Company shall give written notice to the Reinsurer of the pendency
of a claim against the insolvent Company on the Policy or Policies reinsured
within a reasonable time after such claim is filed in the insolvency proceeding
and that during the pendency of such claim, the Reinsurer may investigate such
claim and interpose, at its own expense, in the proceeding when such claim is to
be adjudicated, any defense or defenses which it may deem available to the
Company or its liquidator or receiver or statutory successor. The expense thus
incurred by the Reinsurer shall be chargeable, subject to court approval,
against the insolvent Company as part of the expense of liquidation to the
extent of a proportionate share of the benefit which may accrue to the Company
solely as a result of the defense undertaken by the Reinsurer.

When two or more reinsurers are involved in the same claim and a majority in
interest elects 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 insolvent Company.

Should the Company go into liquidation or should a receiver be appointed, the
Reinsurer shall be entitled to deduct from any sums which may be due or may
become due to the Company under this reinsurance Contract any sums which are due
to the Reinsurer by the Company under this reinsurance Contract and which are
payable at a fixed or stated date as well as any other sums due the Reinsurer
which are permitted to be offset under applicable law.

                                   ARTICLE 23

ARBITRATION

As a condition precedent to any right of action hereunder, any irreconcilable
dispute between the parties to this Contract will be submitted for decision to a
board of arbitration composed of two arbitrators and an umpire meeting in
Seattle, Washington.

Arbitration shall be initiated by the delivery of a written notice of demand for
arbitration by one party to the other within a reasonable time after the dispute
has arisen.

The members of the board of arbitration shall be active or retired disinterested
officials of insurance or reinsurance companies, or Underwriters at Lloyd's,
London, not under the control or management of either party to this Contract.
Each party shall appoint its arbitrator, and the two arbitrators shall choose an
umpire before instituting the hearing. If the respondent fails to


                                    18 of 29

<PAGE>

appoint its arbitrator within four weeks after being requested to do so by the
claimant, the latter shall also appoint the second arbitrator. If the two
arbitrators fail to agree upon the appointment of an umpire within four weeks
after their nominations, each of them shall name three of whom the other shall
decline two, and the decision shall be made by drawing lots.

The claimant shall submit its initial brief within 45 days from appointment of
the umpire. The respondent shall submit its brief within 45 days thereafter, and
the claimant may submit a reply brief within 30 days after filing of the
respondent's brief.

The board shall make its decision with regard to the custom and usage of the
insurance and reinsurance business. The board shall issue its decision in
writing based upon a hearing in which evidence may be introduced without
following strict rules of evidence but in which cross-examination and rebuttal
shall be allowed. The board shall make its decision within 60 days following the
termination of the hearings unless the parties consent to an extension. The
majority decision of the board shall be final and binding upon all parties to
the proceeding. Judgment may be entered upon the award of the board in any court
having jurisdiction.

Each party shall bear the expense of its own arbitrator and shall jointly and
equally bear with the other party the expense of the umpire. The remaining costs
of the arbitration proceedings shall be allocated by the board.

                                   ARTICLE 24

TAXES

A.   In consideration of the terms under which this Contract is issued, the
     Company undertakes not to claim any deduction 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 to the District of
     Columbia.

B.   1.   Each Reinsurer has agreed to allow, for the purpose of paying the
          Federal Excise Tax, 1% of the premium payable hereon to the extent
          such premium is subject to Federal Excise Tax.

     2.   In the event of any return of premium becoming due hereunder, the
          Reinsurer shall deduct 1% from the amount of the return, and the
          Company or its agent should take steps to recover the Tax from the
          U.S. Government.

                                   ARTICLE 25

SERVICE OF SUIT

A.   This Article applies only to those Reinsurers not domiciled in the United
     States of America, and/or not authorized in any state, territory and/or
     district of the United States of America where authorization is required by
     insurance regulatory authorities.

B.   This Article shall not be read to conflict with or override the obligations
     of the parties to arbitrate their disputes as provided for in the
     Arbitration Article. This Article is intended as an aid to compelling
     arbitration or enforcing such arbitration or arbitral award, not as an
     alternative to the Arbitration Article for resolving disputes arising out
     of this Contract.

C.   In the event of the failure of the Reinsurer to pay any amount claimed to
     be due hereunder, the Reinsurer, at the request of the Company, shall
     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. The Reinsurer, once the appropriate court is
     selected, whether such court is the one originally chosen by the Company
     and accepted by Reinsurer or is determined by removal, transfer, or
     otherwise, as provided for above, shall comply with all requirements
     necessary to give said court jurisdiction and, in any suit instituted
     against the Reinsurer upon this Contract, shall abide by the final decision
     of such court or of any appellate court in the event of an appeal.

D.   Service of process in such suit may be made upon Messrs. Mendes and Mount,
     750 Seventh Avenue, New York, New York 10019-6829. The above-named are
     authorized and directed to accept service of process on behalf of the
     Reinsurer in any such suit.

E.   Further, pursuant to any statute of any state, territory or district of the
     United States that makes provision therefor, the Reinsurer hereby
     designates 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, and hereby designates the above-named as the person to whom
     the said officer is authorized to mail such process or a true copy thereof.

                                   ARTICLE 27

OFFSET

The Company or the Reinsurer shall have and may exercise, at any time and from
time to time, the right to offset any balance or balances whether on account of
premiums or on account of


                                    20 of 29

<PAGE>

losses or otherwise, due from one party to the other party hereto under the
terms of this Contract. The party asserting the right of offset shall have and
may exercise such right whether acting in the capacity of assuming reinsurer or
as ceding insurer.

                                   ARTICLE 28

LOSS NOTICES AND SETTLEMENTS

The Company will advise the Reinsurer promptly of all claims which in the
opinion of the Company may involve the Reinsurer and of all subsequent
developments on these claims which may materially affect the position of the
Reinsurer, such advices to include any claim for which the reserve is 50% or
more of the Company's retention and, irrespective of the reserve or of any
question on liability or coverage, any claim falling within the following

The Company may give the Reinsurer written notice of its intentions to pay a
loss on a certain date, and may demand payment of the Reinsurer's share of same
concurrently with payment by the Company to its insured(s), provided however,
the Company gives at least 15 days advance written notice of the date on which
the Company intends to pay the loss to its insured(s), demanding receipt of the
Reinsurer's share of such loss by such day.

The Reinsurer will pay its share of such loss notwithstanding any question or
objection it might have as to whether it is liable for its respective share of
such loss under the terms and conditions of this Contract, provided that the
Company has provided such information as is required to complete the loss
memorandum form with respect to such loss. Notwithstanding the foregoing,
payment of such an amount claimed due by the Company will not constitute a
waiver of a Reinsurer's right to request any amount so paid be returned to the
Reinsurer if it is later found that under the terms and conditions of this
Contract the Reinsurer was not liable for such amount claimed to be due by the
Company. The Company immediately will return to any such Reinsurer any such
amount paid by the Reinsurer that the Reinsurer was not liable to pay under
terms and conditions of this Contract.

FEDERAL TERRORISM EXCESS RECOVERY

A.   A pro rata share of the amount, if any, by which financial assistance paid
     to the Company under the Terrorism Risk Insurance Act of 2002 ("TRIA") for
     Acts of Terrorism occurring during any one Program Year, combined with the
     Company's total private-sector reinsurance recoveries for such Acts of
     Terrorism, exceeds the amount of Insured Losses paid by the Company for
     such Acts of Terrorism, shall be reimbursed by the Company to the
     Reinsurer. Such pro rata share shall be calculated by dividing:

     1.   the Reinsurer's payment under this Contract of Insured Losses for the
          Program Year; by

     2.   the Company's total private-sector reinsurance recoveries arising from
          all Act(s) of Terrorism covered under TRIA during the Program Year.

B.   Payment shall be made as promptly as possible after the Company's receipt
     of any recovery in excess of its Insured Losses. The Company shall provide
     the Reinsurer with all necessary data respecting the transactions covered
     under this Article.

C.   Such payment to the Reinsurer shall apply unless disallowed by the U.S.
     Department of the Treasury.

D.   "Act of Terrorism", "Insured Losses" and "Program Year" shall follow the
     definitions provided in TRIA.

COMMUTATION

This Article will only take effect should the parties hereto mutually agree to
commute losses under this Contract. There will be no obligation on the part of
either party to so commute.

In respect of all losses known to the Company which may have not been finally
settled and which have exceeded the Company's retention under this Contract, at
any time after ten years following the expiration of this Contract and upon
mutual agreement of the Company and the Reinsurer, said loss (including loss
expenses) may be commuted. The amount so commuted will be based on the amount of
loss which exceeds the Company's retention, and will be determined by employing
one of the following alternatives:

A.   A present value calculation based on the following:

     1.   Indemnity benefits discounted for mortality and the time value of
          money. Medical benefits based upon the Company's evaluation of
          long-term medical care and rehabilitation requirements valued at
          current cost levels, escalated at the average Medical Care Consumer
          Price Index for the applicable region (CPIMC) and discounted for
          mortality and the time value of money. The average CPIMC will be taken
          over the five most recent (as of the time of commutation) September
          30th values of the CPIMC.

     2.   The time value of money will be taken as the average five-year U.S.
          Treasury Note yield. The average will be taken over the five most
          recent (as of the time of commutation) September 30th values of the
          yield.

     3.   Mortality will be based on the most recent U.S. Life Table (at the
          time of commutation) unless medical evidence specific to an individual
          case indicates that a reduced life expectancy would be appropriate.

B.   The Company may purchase (or obtain a quotation for) an annuity from any
     carrier who is "A" Class VIII or better rated by A. M. Best Company.

The Reinsurer's proportion of the amount determined will be considered their
total liability for such loss and the lump sum payment thereof will constitute a
complete release of the Reinsurer from their liability for such loss.

The Company and the Reinsurer agree that, should a loss not in excess of the
Company's retention at the time of commutation subsequently exceed the Company's
retention at some future date, such loss may be subject to commutation on the
basis outlined above.

This Commutation Article will survive the expiration of this Contract.

SPECIAL ACCEPTANCES

The Company may submit to the Reinsurer, for special acceptance hereunder,
business not covered by this Contract. If said business is accepted by the
Reinsurer, it will be subject to the terms of this Contract, except as such
terms are modified by such acceptance. Any special acceptance business covered
under the reinsurance agreement being replaced by this Contract will be
automatically covered hereunder. Further, should the Reinsurer become a party to
this Contract subsequent to the acceptance of any business not normally covered
hereunder, they will automatically accept same as being a part of this Contract.

MODE OF EXECUTION

A.   This Contract may be executed by:

     1.   An original written ink signature of paper documents.

     2.   An exchange of facsimile copies showing the original written ink
          signature of paper documents.

     3.   Electronic signature technology employing computer software and a
          digital signature or digitizer pen pad to capture a person's
          handwritten signature in such a manner that the signature is unique to
          the person signing, is under the sole control of the person signing,
          is capable of verification to authenticate the signature and is linked
          to the document signed in such a manner that if the data is changed,
          such signature is invalidated.

B.   The use of any one or a combination of these methods of execution shall
     constitute a legally binding and valid signing of this Contract. This
     Contract may be executed in one or more counterparts, each of which, when
     duly executed, shall be deemed an original.
