                                 Columbus, Ohio
                   (hereinafter referred to as the "Company")

                             Century Surety Company
                                 Columbus, Ohio
                  (hereinafter referred to as the "Reinsurer")


ARTICLE I - BUSINESS REINSURED

By this Contract the Reinsurer agrees to reinsure the Ultimate Net Loss which
has accrued to the Company on losses occurring on or before the effective date
of this Contract under its policies, contracts and binders of insurance or
reinsurance (hereinafter called "policies") issued or renewed prior to the
effective date hereof and classified by the Company as Property and Casualty and
Commercial Auto, subject to the terms, conditions and limitations hereinafter
set forth.

ARTICLE II - TERM

This Contract shall become effective on January 1, 2004, and remain in force
until all outstanding loss and assignable loss adjustment expense covered under
this Contract has been settled or commuted in accordance with the provisions of
this Contract.

ARTICLE III - DEFINITIONS

A.       "Ultimate net loss" as used herein is defined as the sum or sums
         (including assignable loss adjustment expense, as hereinafter defined),
         and unrecoverable reinsurance for outstanding losses, including
         incurred but not reported losses paid 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; provided, however, that in the
         event of the insolvency of the Company, payment by the Reinsurer shall
         be made in accordance with the provisions of Article XIV. 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.


                                       1
<PAGE>
B.       "Assignable loss adjustment expense" as used herein shall mean expenses
         assignable to the investigation, appraisal, adjustment, settlement,
         litigation, defense and /or appeal of specific claims, regardless of
         how such expenses are classified for statutory reporting purposes.
         Assignable loss adjustment expense shall include, but not be limited
         to, interest on judgments, expenses of outside adjusters, and
         declaratory judgment expenses or other legal expenses and costs
         incurred in connection with coverage questions and legal actions
         connected thereto, but shall not include office expenses or salaries of
         the Company's regular employees. If the Company elects or is forced to
         hire a claims handling company to manage its claims, then the cost of
         such shall be excluded from assignable loss adjustment expense.


ARTICLE IV - LOSS NOTICES, SETTLEMENTS AND PAYMENTS

A.       Losses shall be reported as hereinafter provided, except that the
         Company shall promptly notify the Reinsurer of any unusual
         circumstances affecting the Reinsurer's liability hereunder.

B.       All loss settlements made by the Company, provided they are within the
         terms of this Contract shall be binding upon the Reinsurer. The
         Reinsurer agrees to pay all amounts for which it may be liable as
         provided in Article VII.

ARTICLE V - SALVAGE AND SUBROGATION

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

ARTICLE VI - REINSURANCE CONSIDERATION

As consideration for the reinsurance provided hereunder the Company shall
deliver to the Reinsurer in cash or in securities acceptable to the Reinsurer an
amount equal to the sum of the following:

         $13,289 representing case reserves as shown in Exhibit A known as of
         the effective date, net of treaty reinsurance;

         $19,673 representing incurred but not reported reserves ("IBNR")

ARTICLE VII - REPORTS AND REMITTANCES

A.       Within 45 days after the end of each calendar quarter during the term
         of this Contract, the Company shall report to the Reinsurer the
         following:

         1.       Summary of paid losses and assignable loss adjustment expense
                  paid during the quarter;

         2.       Summary of case outstanding losses and assignable loss
                  adjustment expense as of the end of the quarter, including a
                  report of the carried incurred by not reported amounts;

         3.       Any other information needed by the Reinsurer to evaluate this
                  Contract which is reasonably available to the Company.

The loss information shall be segregated by line of business and accident
(report) year.

B.       The Reinsurer shall pay losses within 30 days after receipt of the
         Company's quarterly report or within 75 days after the end of each
         calendar quarter, whichever is later.

ARTICLE VIII - NON-PAYMENT OF PREMIUM

The Reinsurer may terminate this Contract with 30 days prior written notice, and
shall have no liability hereunder, in the event the Company fails to pay any
reinsurance consideration for any reason, including insolvency, within ten
business days of the date such consideration is due. The Company may avoid
termination by paying any and all amounts that are delinquent on or before the
effective date of termination.

ARTICLE IX - OFFSET

The Company and the Reinsurer shall have the right to offset any balance or
amounts due from one party to the other under the terms of this Contract. The
party asserting the right of offset may exercise such right any time whether the
balances due are on account of premiums or losses or otherwise. However, in the
event of the insolvency of any party hereto, offset shall only be allowed in
accordance with applicable law.

ARTICLE X - ACCESS TO RECORDS (BRMA 1D)

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

ARTICLE XI - NET RETAINED LINES (BRMA 32B)

A.       This Contract applies only to that portion of any policy which the
         Company retains net for its own account, and in calculating the amount
         of any loss hereunder and also


                                       3
<PAGE>
         in computing the amount or amounts in excess of which this Contract
         attaches, only loss or losses in respect of that portion 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 such inability
         arises from the insolvency of such other reinsurers(s) or otherwise.

ARTICLE XII - ERRORS AND OMISSIONS (BRMA 14F)

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

ARTICLE XIII - TAXES (BRMA 50B)

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

ARTICLE XIV - INSOLVENCY

A.       In the event of the insolvency of the reinsured company, 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 with 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.


                                       4
<PAGE>
B.       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 XV - ARBITRATION

A.       As a condition precedent to any right of action, hereunder, in the
         event of any dispute or difference of opinion hereafter arising with
         respect to this Contract, it is hereby mutually agreed that such
         dispute or difference of opinion shall be submitted to arbitration. One
         Arbiter shall be chosen by the Company, the other by the Reinsurer, and
         an Umpire shall be chosen by the two Arbiters before they enter upon
         arbitration, all of whom shall be active or retired disinterest
         executive officers of insurance or reinsurance companies. 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.       Each party shall bear the expense of its own Arbiter, and shall jointly
         and equally bear with the other the expense of the Umpire 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.

D.       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 of Ohio.

ARTICLE XVI - SERVICE OF SUIT (BRMA 49D)

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

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

B.   Further, pursuant to any statute of any state, territory or district of the
     United States which makes provision therefore, the Reinsurer hereby
     designates the Superintendent, Commissioner or Director of Insurance or
     other officer specified for the purpose in the statute, or his successor or
     successors in office, as its true and lawful attorney upon who may be
     served any lawful process in any action, suit or proceeding instituted by
     or on behalf of the Company or any beneficiary hereunder arising out of
     this Contract.

ARTICLE XVII - GOVERNING LAW

The Contract shall be governed by and construed in accordance with the laws of
the State of Ohio.

ARTICLE XVIII - AGENCY AGREEMENT

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