                        INVESTMENT MANAGEMENT AGREEMENT

     THIS INVESTMENT MANAGEMENT AGREEMENT (this "Agreement"), dated as of August
31, 2000, is made by and between HAMBLIN WATSA INVESTMENT COUNSEL LTD. and
SENECA INSURANCE COMPANY, INC. As used in this Agreement, "we", "us" and "our"
shall refer to SENECA INSURANCE COMPANY, INC., and "you" and "your" shall refer
to HAMBLIN WATSA INVESTMENT COUNSEL LTD.

     In consideration of the mutual promises contained herein, the parties agree
as follows:

1.   We authorize you to manage on a continuous basis an investment account (the
     "Account") on our behalf on the terms and conditions set out in this
     Agreement.

2.   You shall manage the Account in accordance with the investment objectives
     from time to time communicated in writing by us to you. Until mutually
     agreed otherwise, the investment guidelines shall be as set out in the
     investment guidelines attached hereto as Schedule A. The investment
     guidelines shall at all times be in compliance with the legal investment
     statutes of the State of New York.

3.   Subject to Section 2 above, you shall manage the Account in our name and
     you are hereby authorized to take such action for the Account as you, in
     your sole discretion, may consider appropriate for the operation of the
     Account including, without limitation, the power to buy, sell and exchange
     and otherwise deal in all securities which may at any time form part of the
     Account and to invest, in securities selected by you, all funds contained
     in, paid to or derived from the operation of, the Account, except to the
     extent that you are otherwise instructed in writing by us.

4.   The securities and funds of the Account have been deposited with and shall
     be held by BANK OF NEW YORK (the "Custodian") at its principal custodian
     office in the State of New York (or with such other custodian as is chosen
     by you from time to time and is acceptable to the Insurance Department of
     the State of New York (the "Department")) pursuant to an agreement which we
     have entered into with the Custodian. We have instructed the Custodian to
     follow your directions promptly at all times and to provide you with all
     such information concerning the Account as you may from time to time
     require in connection with your management of the Account, including
     without limitation, copies of relevant monthly statements.

5.   Provided you have used reasonable care and diligence you shall not be
     responsible for any damage, loss, cost or other expense sustained in the
     operation of the Account or relating in any manner to the carrying out of
     your duties under this Agreement. We agree that you shall be entitled to
     assume that any information communicated by us or the Custodian to you is
     accurate and complete, and that in making investment decisions you shall be
     entitled to rely on publicly available information or on information which
     you believe to have been provided to you in good faith, in both cases
     barring actual knowledge by you to the contrary.

6.   You shall be entitled to such fees, payable quarterly in arrears, for your
     management of the Account as you may specify from time to time. Attached
     hereto as Schedule B is a copy of your current fee schedule and you agree
     to give us thirty (30) days prior written notice of any change in such
     schedule, which change shall require the approval of the Department. Such
     fees shall be the exclusive fees and charges payable (excluding third party
     disbursements reasonably incurred) for your management of the Account. As
     regards third party services, you will charge us only the amount of your
     actual disbursements paid to arm's length third parties for such services,
     and you will select as agents, brokers or dealers executing orders or
     acting on the purchase or sale of portfolio securities only agents, brokers
     or dealers operating in the United States. We shall have the right to
     disapprove the selection of brokers and dealers provided that a reasonable
     basis exists for such disapproval.

7.   You shall deliver in writing to us, as soon as practicable after
     implementation of an investment decision, your confirmation of such
     implementation to enable us to ascertain that such implementation has been
     effected pursuant to the guidelines and procedures of our Board of
     Directors or a duly authorized committee thereof. In addition, you shall
     deliver in writing to us within 20 days after the end of each month a
     monthly transaction report which shall be submitted to the Board of
     Directors or a duly authorized committee thereof for approval at its
     regularly scheduled meetings or at any special meeting called for that
     purpose. Otherwise,
<PAGE>

     the nature and timing of your reporting to us on the status of the Account
     shall be at least quarterly, within 45 days after the end of each quarter.

8.   We acknowledge receipt of a copy of policies that you have established to
     ensure that investment opportunities are allocated fairly among your
     discretionary investment accounts and we confirm that these policies, until
     revised by you, will apply to the account.

9.   Either party hereto may terminate this Agreement without penalty by giving
     the other party at least thirty (30) days advance written notice of its
     desire to terminate the same. In the event that the day upon which this
     Agreement is so terminated is a day other than the first day of a calendar
     quarter, the fees payable in accordance with paragraph 6 for such quarter
     shall be pro-rated and shall be determined having regard to the market
     value of the Account based upon the most recent financial report which has
     been delivered to you by the Custodian.

10. This Agreement shall enure to the benefit of and shall be binding upon the
    parties hereto and their respective successors. This Agreement may not be
    assigned by either party.

11. We acknowledge that we have read and understood this Agreement and that we
    have received a copy of the same. You and we each acknowledge that the terms
    of this Agreement are the exclusive and conclusive terms of our mutual
    agreement with regard to the subject matter hereof.

12. Any dispute or difference arising with reference to the applicable
    interpretation or effect of this Agreement, or any part thereof, shall be
    referred to a Board of Arbitration (the "Board") of two (2) arbitrators and
    an umpire.

     The members of the Board shall be active or retired disinterested officers
     of insurance or reinsurance companies.

     One arbitrator shall be chosen by the party initiating the arbitration and
     designated in the letter requesting arbitration. The other party shall
     respond, within fifteen (15) days, advising of its arbitrator. The umpire
     shall thereafter be chosen by the two (2) arbitrators. In the event either
     party fails to designate its arbitrator as indicated above, the other party
     is hereby authorized and empowered to name the second arbitrator, and the
     party which failed to designate its arbitrator shall be deemed to have
     waived its rights to designate an arbitrator and shall not be aggrieved
     thereby. The two (2) arbitrators shall then have thirty (30) days within
     which to choose an umpire. If they are unable to do so within thirty (30)
     days following their appointment, each arbitrator shall nominate three
     candidates within ten (10) days thereafter, two of whom the other shall
     decline, and the decision shall be made by drawing lots. In the event of
     the death, disability or incapacity of an arbitrator or the umpire, a
     replacement shall be named pursuant to the process which resulted in the
     selection of the arbitrator or umpire to be replaced.

     Each party shall submit its case to the Board within one (1) month from the
     date of the appointment of the umpire, but this period of time may be
     extended by unanimous written consent of the Board.

     The sittings of the Board shall take place in New York, New York. The Board
     shall make its decision with regard to the custom and usage of the
     insurance and reinsurance business. The Board is released from all judicial
     formalities and may abstain from the strict rules of law. The written
     decision of a majority of the Board shall be rendered within sixty (60)
     days following the termination of the Board's hearings, unless the parties
     consent to an extension. Such majority decision of the Board shall be final
     and binding upon the parties both as to law and fact, and may not be
     appealed to any court of any jurisdiction. Judgment maybe entered upon the
     final decision of the Board in any court of proper jurisdiction.

     Each party shall bear the fees and expenses of the arbitrator selected by
     or on its behalf, and the parties shall bear the fees and expenses of the
     umpire as determined by the party, as above provided, the expenses of the
     arbitrators, the umpire and the arbitration shall be equally divided
     between the two parties. The arbitrators may allocate any and all of the
     costs and fees against the losing party upon a determination that the
     position of the losing party was, in whole or in part, groundless, specious
     or otherwise without merit or asserted primarily for the purposes of
     obfuscation or delay.

                                   SCHEDULE A

INVESTMENT OBJECTIVES

1.   Investment for the long term always providing sufficient liquidity for the
     payment of claims and other policy obligations.

2.   Ensure preservation of invested capital for policyholder protection.

3.   Invest in accordance with insurance regulatory guidelines.

INVESTMENT GUIDELINES

1.   Approach

     All investments are to be made using the value approach by investing in
     companies at prices below their underlying long term values to protect
     capital from loss and earn income over time and provide operating income as
     needed.

     With regard to equities, no attempt is made to forecast the economy or the
     stock market. The manager will attempt to identify financially sound
     companies with good potential profitability which are selling at large
     discounts to their intrinsic value. Appropriate measures of low prices may
     consist of some or all of the following characteristics: low price earnings
     ratios, high dividend yields, significant discounts to book value, and free
     cash flow. Downside protection is obtained by seeking a margin of safety in
     terms of a sound financial position and a low price in relation to
     intrinsic value. Appropriate measures of financial integrity which are
     regularly monitored, include debt/equity ratios, financial leverage, asset
     turnover, profit margin, return on equity, and interest coverage.

     As a result of this bargain hunting approach, it is anticipated that
     purchases will be made when economic and issue-specific conditions are less
     than ideal and sentiment is uncertain or negative. Conversely, it is
     expected that gains will be realized when issue-specific factors are
     positive and sentiment is buoyant. The investment time horizon is one
     business cycle (approximately 3-5 years).

     As regards bonds, the approach is similar. No attempt is made to forecast
     the economy or interest rates. The manager will attempt to purchase
     attractively priced bonds offering yields better than Treasury bonds with
     maturities of 10 years or less that are of sound quality i.e. whose
     obligations are expected to be fully met as they come due. We do not regard
     rating services as being an unimpeachable source for assessing credit
     quality any more than we would regard a broker's recommendation on a stock
     as being necessarily correct. In any form of investment research and
     evaluation, there is no substitute for the reasoned judgement of the
     investment committee and its managers.

2.   Liquidity

     An adequate cash flow should be maintained to ensure that claims and
     operating expenses are paid on a timely basis. An operating cash position
     is to be maintained at appropriate levels and will be managed by the
     insurance operating company in accordance with the approved list for
     investments as determined from time to time by the Investment Committee.
     These securities will be managed by the Insurance Company as part of the
     Treasury function and currently are restricted primarily to Treasury and
     Agency securities of the U.S. government.

3.   Regulatory

     Insurance regulations will be complied with, specifically Article 14 of the
     New York Insurance Law.

4.   Diversification

     The portfolio is to be invested in a wide range of securities of different
     issuers operating in different industries and jurisdictions in order to
     minimize risk.

                                       A-1
<PAGE>

5.   Prudent Person Rule

     Prudent investment standards are considered in the overall context of an
     investment portfolio and how a prudent person would invest another person's
     money without undue risk of loss or impairment and with a reasonable
     expectation of fair return.

STRATEGY

1.   Maintain Adequate Liquidity

     A review of portfolio liquidity is undertaken on a monthly basis. The
     liquidity analysis determines how much of each portfolio can be converted
     to cash in a given time period. Each company determines its liquidity
     requirements and the liquidity of the portfolio must match the requirement.

2.   Asset Allocation

     The asset allocation will be determined by the Portfolio Manager and will
     include short term investments that will generate appropriate cash flows
     and long term investments in stocks, bonds, debentures and money market
     investments, both domestic and foreign. The allocation will be in
     compliance with regulatory guidelines and should meet policy liabilities.

3.   Foreign Exchange Risk

     Any foreign currency investments and exposures would normally be hedged via
     the use of forward foreign exchange contracts and/or currency options or
     preferably by a natural hedge with foreign pay liabilities of the Insurance
     Company. Unhedged foreign investments will be limited to 10% of invested
     assets at cost if judged appropriate. Unhedged exposure above this amount
     must be approved by the Investment Committee.

4.   Interest Rate Risk

     Interest rate risk will be minimized primarily through investment in fixed
     income securities with maturities less than ten years. While there are no
     specific duration/maturity limits for convertible securities, these issues
     are included in the total fixed income duration/term measure. Maximum fixed
     income portfolio duration is limited to the equivalent of a ten year term
     to maturity Treasury security.

INVESTMENT POLICY MIX

     The Investment Committee has established the following exposure ranges for
various asset mix classes:

<Table>
<Caption>
                                                               RANGE
                                                              --------
<S>                                                           <C>
Equities....................................................  0-25%
Fixed Income................................................  0-100%
Cash........................................................  Residual
Total.......................................................  100%
</Table>

     Within the Fixed Income portfolio, the Taxable/Tax Exempt mix will be
determined relative to the consolidated tax position of the Insurance Company
and the relative investment attractiveness of available tax exempt securities.

     The Investment Committee will control the total asset mix and will give
performance objectives to the Investment Manager regarding the assets managed.

RETURN EXPECTATIONS

     Total asset mix policy is expected on an annual basis to result in returns
better than the Consumer Price Index plus 3% over a ten year period before the
disbursement of investment management fees. However, in any one year the annual
return may be significantly above or below this expectation.

INVESTMENT OBJECTIVE OF THE FUND MANAGER

     The Manager, subject to regulatory and company imposed constraints
mentioned elsewhere, expects to provide additional returns to those returns that
would be earned by the alternative of passively managing a surrogate market
index.

     Performance of the Fund Manager is expected to result in the following
returns:

     Downgrades will be taken into account when making new investments but will
not necessarily result in the sale of existing positions.

Investment Manager and included as part of the categories above for the purposes
of determining overall exposure by quality tier.

     Any exceptions to the above must be approved by the Investment Committee.

                          MASTER REPURCHASE AGREEMENT

     Effective as of July 1, 2000 by and between Crum & Forster Indemnity
Company ("C&F Indemnity") and Fairfax Financial Holdings Limited ("Fairfax").

     WHEREAS, C&F Indemnity, in the normal course of its business, may from time
to time agree to pay claims to policyholders that require it to sell or
otherwise liquidate certain securities or other invested assets in order to
raise sufficient cash to make such payments; and

     WHEREAS, C&F Indemnity typically pays policyholder claims prior to
receiving reimbursement for such claims from its reinsurers, requiring C&F
Indemnity to make cash payments on claims that can greatly exceed its ultimate
net liability for such claims and creating a timing gap between payments by C&F
Indemnity and recovery from its reinsurers; and

     WHEREAS, Fairfax, as the indirect owner of C&F Indemnity, has an interest
in maximizing the return on invested assets of C&F Indemnity; and

     WHEREAS, Fairfax seeks to assist C&F Indemnity in managing its cash flow to
eliminate or minimize investment losses resulting from the sale or liquidation
of securities in order to cover short-term cash requirements.

     NOW, THEREFORE, for due and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties agree as follows:

1.   TRANSACTIONS

     From time to time, the parties hereto may enter in to transactions (each a
     "Transaction") in which C&F Indemnity agrees to transfer to Fairfax certain
     securities ("Securities") against the transfer of an amount in United
     States dollars equal to the fair market value of such Securities on the
     date of transfer, such amount not to exceed U.S. $5,000,000 singly or, when
     combined with amounts then outstanding from any other Transaction, in the
     aggregate (the "Purchase Price") by Fairfax to C&F Indemnity and Fairfax
     agrees to transfer to C&F Indemnity such Securities on a date to be agreed
     by Fairfax and C&F Indemnity and which shall be on or before December 31 of
     the year during which such transfer is made (the "Repurchase Date"),
     against the transfer of funds by C&F Indemnity.

2.   REPURCHASE

     C&F Indemnity shall repurchase the Securities from Fairfax on or before the
     Repurchase Date for an amount not to exceed the sum of the Purchase Price
     and the aggregate amount obtained by daily application of the stated
     interest rate of each Security to the Purchase Price paid for such Security
     on a 360 day per year basis for the actual number of days during the period
     commencing on the (and including) the Purchase Date and ending on (but
     excluding) the Repurchase Date.

3.   INCOME PAYMENTS

     C&F Indemnity shall be entitled to receive, with respect to any Security at
     any time, an amount equal to any principal thereof and all interest,
     dividends or other distributions thereon ("Income") paid or distributed in
     respect of the Securities that are not otherwise received by C&F Indemnity
     to the full extent it would be so entitled if the Securities had not been
     sold to Fairfax. Fairfax shall, as the parties may agree (or, in the
     absence of any such agreement, as Fairfax shall reasonably determine in its
     discretion), on the date such Income is paid or distributed either (i)
     transfer to or credit to the accounts of C&F Indemnity such Income with
     respect to any Securities or (ii) with respect to Income paid in cash,
     apply the Income payment or payments to reduce the amount, if any, to be
     transferred to Fairfax by C&F Indemnity upon termination of the
     Transaction.

                                        1
<PAGE>

4.   SECURITY INTEREST

     Although the parties intend that the Transaction be a sale and purchase and
     not a loan, in the event the Transaction is deemed to be a loan, C&F
     Indemnity shall be deemed to have pledged to Fairfax as security for the
     performance by C&F Indemnity of its obligations under the Transaction, and
     shall be deemed to have granted to Fairfax a security interest in, all of
     the Securities and all income thereon and other proceeds thereof.

5.   PAYMENT AND TRANSFER

     Unless otherwise mutually agreed, all transfers of funds hereunder shall be
     in immediately available funds. All Securities transferred by one party
     hereto to the other party (i) shall be in suitable form for transfer or
     shall be accompanied by duly executed instruments of transfer or assignment
     in blank and such other documentation as the party receiving possession may
     reasonably request, (ii) shall be transferred on the book-entry system of a
     Federal Reserve Bank, or (iii) shall be transferred by any other method
     mutually acceptable to C&F Indemnity and Fairfax.

6.   SEGREGATION OF SECURITIES

     To the extent required by applicable law, all Securities in the possession
     of Fairfax shall be segregated from other securities in its possession and
     shall be identified as subject to this Agreement. Segregation may be
     accomplished by appropriate identification on the books and records of the
     holder, including a financial or securities intermediary or a clearing
     corporation. All of C&F Indemnity's interest in the Securities shall pass
     to Fairfax on the Purchase Date and, unless otherwise agreed by Fairfax and
     C&F Indemnity, nothing in this Agreement shall preclude Fairfax from
     engaging in repurchase transactions with the Securities or otherwise
     selling, transferring, pledging or hypothecating the Securities, but no
     such transaction shall relieve Fairfax of its obligations to transfer
     Securities to C&F Indemnity pursuant to Paragraph 2 hereof, or of Fairfax's
     obligation to credit or pay Income to, or apply Income to the obligations
     of, C&F Indemnity pursuant to Paragraph 3 hereof.
