REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of Arch Capital Group Ltd.:

We have reviewed the accompanying consolidated balance sheet of Arch Capital Group Ltd. and its subsidiaries as of June 30, 2002, and the related consolidated statements of income for each of the three and six month periods ended June 30, 2002 and 2001, and the consolidated statements of comprehensive income, changes in shareholders' equity, and cash flows for each of the six month periods ended June 30, 2002 and 2001. These financial statements are the responsibility of the Company's management.

We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited in accordance with auditing standards generally accepted in the United States of America, the consolidated balance sheet as of December 31, 2001, and the related consolidated statements of income, comprehensive income and changes in shareholders' equity, and of cash flows for the year then ended (not presented herein), and in our report dated February 28, 2002, except as to the matters described in Note 18 to the consolidated financial statements which are as of March 7, 2002, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet information as of December 31, 2001, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

The interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP") and include the accounts of Arch Capital Group Ltd. ("ACGL") and its subsidiaries (together with ACGL, the "Company"), including Arch Reinsurance Ltd. ("Arch Re Bermuda"), Arch Capital Group (U.S.) Inc. ("Arch-U.S."), Arch Reinsurance Company ("Arch Re U.S."), Arch Insurance Company ("Arch Insurance"), formerly known as First American Insurance Company, Arch Excess & Surplus Insurance Company ("Arch E&S"), formerly known as Cross River Insurance Company, Arch Specialty Insurance Company ("Arch Specialty"), formerly known as Rock River Insurance Company, Arch Risk Transfer Services Ltd. ("ART Services"), American Independent Insurance Holding Company ("AIHC"), and Hales & Company Inc. ("Hales"). All significant intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary (consisting only of normal recurring accruals) for a fair statement of results on an interim basis. The results of any interim period are not necessarily indicative of the results for a full year or any future periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations; however, management believes that the disclosures are adequate to make the information presented not misleading. This report should be read in conjunction with the Company's annual report on Form 10-K for the year ended December 31, 2001, including the Company's audited consolidated financial statements and related notes and the section entitled "Risk Factors." Many events, such as natural catastrophes such as earthquakes, hurricanes, tornados and hailstorms, can have a significant impact on the results of any one or more reporting periods.

In October 2001, the Company launched an underwriting initiative to meet current and future demand in the global insurance and reinsurance markets that included the recruitment of new management teams and an equity capital infusion of $763.2 million. In April 2002, the Company completed an offering of 7,475,000 of its common shares and received net proceeds of $179.2 million. Due to the significant changes in the Company's business and operations resulting from the new underwriting initiative and related capital infusions, comparisons of 2002 to 2001 results are not meaningful.

2. ACCOUNTING PRONOUNCEMENTS

In August 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which was adopted by the Company on January 1, 2002. SFAS No. 144 addresses the accounting and reporting for impairment of long-lived assets to be held and used, as well as long-lived assets to be disposed of. The standard requires that long-lived assets to be held and used will be written down to fair value when they are considered impaired. Long-lived assets to be disposed of are required to be carried at the lower of carrying amount or fair value less estimated cost to sell. SFAS No. 144 also broadens the presentation of discontinued operations on the income statement to include a component of an entity (rather than a segment of a business). The adoption of this standard did not have a material effect on the Company's results of operations for the three month and six month periods ended June 30, 2002 or its financial position.

In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146 will be applied prospectively to exit or disposal activities initiated after December 31, 2002 and requires companies to recognize costs associated with exit activities when they are incurred, rather than at the date of a commitment to an exit or disposal plan. The Company is currently evaluating this standard.

3. RECLASSIFICATIONS

To facilitate period to period comparisons, certain amounts in the 2001 consolidated financial statements have been reclassified to conform to the 2002 presentation. Such reclassifications had no effect on the Company's net income, shareholders' equity or cash flows.

4. GOODWILL

In June 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible Assets," which became effective for the Company on January 1, 2002. In adopting SFAS No. 142, the Company discontinued amortizing goodwill and will test goodwill at least annually for impairment. SFAS No. 142 also requires that, upon adoption, the Company complete a transitional goodwill impairment test six months from the date of adoption. The Company tested its goodwill for impairment at each reporting unit as of January 1, 2002 in accordance with SFAS No. 142 and, based on such evaluation, it was determined that goodwill was not impaired. Goodwill will be tested for impairment on an annual basis and between annual tests in certain circumstances.

The carrying amount of goodwill at June 30, 2002 was $28.8 million, consisting of $23.1 million relating to the Company's insurance subsidiaries ($13.6 million, $6.7 million and $2.8 million relating to the acquisitions of AIHC, ART Services and Arch Specialty, respectively) and $5.7 million relating to the acquisition of Hales.

The following table provides the pro forma effect on net income and basic and diluted earnings per share for the three and six month periods ended June 30, 2002 and 2001, as if the amortization of goodwill had ceased at the beginning of 2001 (net of taxes):

5. CONTINGENCIES RELATING TO THE SALE OF PRIOR REINSURANCE OPERATION

On May 5, 2000, the Company sold the prior reinsurance operations of Arch Re U.S. pursuant to an agreement entered into as of January 10, 2000 with Folksamerica Reinsurance Company and Folksamerica Holding Company (collectively, "Folksamerica"). The Folksamerica transaction was structured as a transfer and assumption agreement (and not reinsurance), and, accordingly, the loss reserves (and any related reinsurance recoverables) relating to the transferred business are not included as assets or liabilities on the Company's balance sheet. Folksamerica assumed Arch Re U.S.'s rights and obligations under the reinsurance agreements transferred in the asset sale. The reinsureds under such agreements were notified that Folksamerica had assumed Arch Re U.S.'s obligations and that, unless the reinsureds object to the assumption, Arch Re U.S. will be released from its obligations to those reinsured. None of such reinsureds objected to the assumption. However, Arch Re U.S. will continue to be liable under those reinsurance agreements if the notice is found not to be an effective release by the reinsureds. Folksamerica has agreed to indemnify the Company for any losses arising out of the reinsurance agreements transferred to Folksamerica Reinsurance Company in the asset sale. However, in the event that Folksamerica refuses or is unable to perform its obligations to the Company, Arch Re U.S. may incur losses relating to the reinsurance agreements transferred in the asset sale. Folksamerica has an A.M. Best rating of "A-" (Excellent).

Under the terms of the agreement, $20 million of the purchase price had been placed in escrow for a period of five years. Such amounts represented restricted funds that appeared under a separate caption entitled "Securities held in escrow" on the Company's consolidated balance sheet at December 31, 2001. These funds were to be used to reimburse Folksamerica if the loss reserves (which were $32.3 million at the closing of the asset sale) transferred to it in the asset sale relating to business produced on behalf of Arch Re U.S. by a certain managing underwriting agency were deficient as measured at the end of such five-year period or to satisfy certain indemnity claims Folksamerica may have had during such period. On February 25, 2002, the Company reached a definitive settlement agreement with Folksamerica pursuant to which the Company satisfied its obligations under the escrow agreement for consideration of $17.0 million, plus accrued interest income of $1.8 million. Accordingly, during the 2001 fourth quarter, the Company recorded an after-tax benefit of $0.4 million, which consisted of a charge of $2.5 million, offset by a reversal of a related reserve in the amount of $2.9 million. The related reserve had been provided for the purchase of reinsurance, which was no longer required due to the fact that the escrow arrangements have been terminated under the above settlement agreement.

Under the terms of the agreement, the Company had also purchased in 2000 reinsurance protection covering the Company's transferred aviation business to reduce the net financial loss to Folksamerica on any large commercial airline catastrophe to $5.4 million, net of reinstatement premiums. Although the Company believes that any such net financial loss will not exceed $5.4 million, the Company has agreed to reimburse Folksamerica if a loss is incurred that exceeds $5.4 million for aviation losses under certain circumstances prior to May 5, 2003. The Company also made representations and warranties to Folksamerica about the Company and the business transferred to Folksamerica for which the Company retains exposure for certain periods, and made certain other agreements, including that the Company would not compete with Folksamerica to acquire or reinsure any treaties included in the assumed business until May 5, 2004. Although Folksamerica has not asserted that any amount is currently due under any of the indemnities provided by the Company under the asset purchase agreement, Folksamerica has indicated a potential indemnity claim under the agreement in the event of the occurrence of certain future events. Based on all available information, the Company has denied the validity of any such potential claim. In addition, the Company retained its tax and employee benefit liabilities and other liabilities not assumed by Folksamerica, including all liabilities not arising under reinsurance agreements transferred to Folksamerica in the asset sale and all liabilities (other than liabilities arising under reinsurance agreements) arising out of or relating to the managing underwriting agency referred to above.

6. SEGMENT INFORMATION

The Company classifies its businesses into two underwriting segments - reinsurance and insurance - and a corporate segment (non-underwriting). Segment performance is evaluated based on underwriting income or loss. Other revenue and expense items are not evaluated by segment. In addition, the Company does not manage its assets by segment and, accordingly, investment income is not allocated to each segment. The accounting policies of the segments are the same as those used for the consolidated financial statements. Inter-segment insurance business is allocated to the segment accountable for the underwriting results in accordance with SFAS No. 131.

The reinsurance segment consists of the Company's reinsurance underwriting subsidiaries, Arch Re Bermuda, based in Bermuda, and Arch Re U.S., based in the United States. The reinsurance segment's strategy is to write significant portions of business on a select number of specialty property and casualty treaties. Classes of business focused on include property catastrophe reinsurance, other property business (losses on a single risk, both excess of loss and pro rata), casualty, other specialty business, marine, aviation and space, casualty clash and non-traditional business.

The insurance segment includes the Company's primary underwriting subsidiaries, which include Arch Insurance, Arch Specialty, Arch E&S and American Independent. The insurance segment is comprised of six profit centers including property, casualty, executive assurance, healthcare, professional liability insurance and program business, and other (currently identified as the non-standard auto business of American Independent and the lenders business of Arch Insurance).

The corporate segment (non-underwriting) includes net investment income and net realized gains or losses and other corporate expenses incurred by the Company. The corporate segment also includes the results of Hales, the Company's merchant banking subsidiary. Due to the significant changes in the Company's business and operations resulting from the new underwriting initiative and related capital infusions, comparisons of 2002 and 2001 results are not meaningful. Accordingly, segment information provided below relates solely to 2002 periods. The following tables set forth an analysis of the Company's underwriting income or loss by segment, together with a reconciliation of underwriting income or loss to net income for the three month and six month periods ended June 30, 2002.

7. REINSURANCE

In the normal course of business, the Company's insurance subsidiaries cede a portion of their premium through quota share, surplus, excess of loss and facultative reinsurance agreements. The Company's reinsurance subsidiaries are currently retaining substantially all of their assumed reinsurance premiums written. Reinsurance recoverables are recorded as assets, predicated on the reinsurers' ability to meet their obligations under the reinsurance agreements. If the reinsurers are unable to satisfy their obligations under the agreements, the Company's insurance subsidiaries would be liable for such defaulted amounts.

With respect to 2002 and 2001 results reflected below, the following table sets forth the effects of reinsurance on the Company's reinsurance and insurance subsidiaries to unaffiliated reinsurers. With respect to 2001 results, the table sets forth the effects of reinsurance on American Independent only, which was acquired by the Company in February 2001.

10. INCOME TAXES

ACGL is incorporated under the laws of Bermuda and, under current Bermuda law, is not obligated to pay any taxes in Bermuda based upon income or capital gains. The Company has received a written undertaking from the Minister of Finance in Bermuda under the Exempted Undertakings Tax Protection Act 1966 that, in the event that any legislation is enacted in Bermuda imposing any tax computed on profits, income, gain or

17

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES

10. INCOME TAXES (CONTINUED)

appreciation on any capital asset, or any tax in the nature of estate duty or inheritance tax, such tax will not be applicable to ACGL or any of its operations until March 28, 2016. This undertaking does not, however, prevent the imposition of taxes on any person ordinarily resident in Bermuda or any company in respect of its ownership of real property or leasehold interests in Bermuda.

ACGL will be subject to U.S. federal income tax only to the extent that it derives U.S. source income that is subject to U.S. withholding tax or income that is effectively connected with the conduct of a trade or business within the U.S. and is not exempt from U.S. tax under an applicable income tax treaty with the U.S. ACGL will be subject to a withholding tax on dividends from U.S. investments and interest from certain U.S. taxpayers. ACGL does not consider itself to be engaged in a trade or business within the U.S. and, consequently, does not expect to be subject to direct U.S. income taxation. However, because there is uncertainty as to the activities which constitute being engaged in a trade or business within the United States, there can be no assurances that the U.S. Internal Revenue Service will not contend successfully that ACGL or its non-U.S. subsidiaries are engaged in a trade or business in the United States. If ACGL or any of its non-U.S. subsidiaries were subject to U.S. income tax, ACGL's shareholders' equity and earnings could be materially adversely affected. ACGL's U.S. subsidiaries are subject to U.S. income taxes on their worldwide income.

ACGL changed its legal domicile from the United States to Bermuda in November 2000. Legislation has been introduced which (if enacted) could eliminate the tax benefits available to companies that have changed their legal domiciles to Bermuda, and such legislation may apply to ACGL. In addition, some U.S. insurance companies have been lobbying Congress to pass legislation intended to eliminate certain perceived tax advantages of U.S. insurance companies with Bermuda affiliates resulting principally from reinsurance between or among U.S. insurance companies and their Bermuda affiliates. This legislation, if passed, and other changes in U.S. tax laws, regulations and interpretations thereof to address these issues could materially adversely affect the Company.

For the six months ended June 30, 2002, the Company's income tax provision resulted in an effective tax rate of 14.5%, excluding the reversal of a $7.4 million valuation allowance on certain of the Company's deferred tax assets during the 2002 second quarter. The Company's remaining valuation allowance is $2.1 million at June 30, 2002. The effective tax rate will fluctuate based on the relative amounts of the Company's U.S.-sourced income and its worldwide income. The valuation allowance reversal was based on the Company's recently completed restructuring of its U.S.-based insurance underwriting operations and its business plan.

11. RELATED PARTY TRANSACTIONS

In April 2002, pursuant to agreements entered into in November 2001 in connection with the Company's new underwriting initiative, a subsidiary of ACGL made a non-recourse loan of $13.5 million to Robert Clements, the Chairman of ACGL's Board of Directors, which was used to pay income and self employment taxes, payable in April 2002, on 1,668,157 restricted shares granted to him on October 23, 2001. The loan is secured by such shares, and bears interest at a rate of 4.6% per annum and will mature on the October 23, 2006. If the Company terminates Mr. Clements' service as Chairman for cause, the loan will become immediately payable. Mr. Clements will receive additional compensation in cash in an amount sufficient to defray the interest cost. In addition, the Company has agreed to make gross-up payments to him in the event of certain tax liabilities.

In connection with the Company's information technology initiative in 2002, the Company has entered into arrangements with two software companies, which provide document management systems and information and research tools to insurance underwriters, in which Mr. Clements and John Pasquesi, the Vice Chairman of ACGL's Board of Directors, each own minority ownership interests. The Company will pay fees under such arrangements based on usage. Under one of these agreements, fees payable are subject to a minimum of approximately $575,000 for the two-year period ending July 2004.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
.

GENERAL

THE COMPANY

We are a Bermuda public limited liability company with over $1.2 billion in equity capital and, through operations in Bermuda and the United States, are positioned to write insurance and reinsurance on a worldwide basis. While we are positioned to provide a full range of property and casualty insurance and reinsurance lines, we are focusing on writing specialty lines of insurance and reinsurance.

NEW UNDERWRITING INITIATIVE

In October 2001, we launched an underwriting initiative to meet current and future demand in the global insurance and reinsurance markets that included the recruitment of new insurance and reinsurance management teams and an equity capital infusion of $763.2 million. It is our belief that our existing Bermuda and U.S.-based underwriting platform, our strong management team and our $1.2 billion in capital that is unencumbered by significant exposure to pre-2002 risks have enabled us both to establish an immediate presence in an attractive insurance and reinsurance marketplace. In April 2002, we completed an offering of 7,475,000 of our common shares and received net proceeds of $179.2 million, which were contributed to the surplus of Arch Re Bermuda, our Bermuda-based reinsurance and insurance subsidiary.

This discussion and analysis contains forward-looking statements which involve inherent risks and uncertainties. All statements other than statements of historical fact are forward-looking statements. These statements are based on our current assessment of risks and uncertainties. Actual results may differ materially from those expressed or implied in these statements. Important factors that could cause actual events or results to differ materially from those indicated in such statements are discussed in this report, including the section entitled "--Cautionary Note Regarding Forward Looking Statements," and the section entitled "Risk Factors" included in our Annual Report on Form 10-K for the year ended December 31, 2001.

CRITICAL ACCOUNTING POLICIES, ESTIMATES AND RECENT ACCOUNTING PRONOUNCEMENTS

The preparation of consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities (including reserves), revenues and expenses, and related disclosures of contingent liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, insurance and other reserves, reinsurance recoverables, intangible assets, bad debts, income taxes, pensions, contingencies and litigation. We base our estimates on historical experience, where possible, and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and such differences may be material. As a relatively new insurance and reinsurance company, very limited historical information has been reported to us as of June 30, 2002. We believe that the following critical accounting policies require our more significant judgments and estimates used in the preparation of our consolidated financial statements.

PREMIUM REVENUES AND RELATED EXPENSES

Insurance premiums written are recorded in accordance with the terms of the underlying policies. Reinsurance premiums assumed are recognized as income on a straight line basis over the terms of the related reinsurance contracts. For business written on a pro rata basis, premiums written are recorded as the underlying policies are written, generally over a twelve-month period. For excess of loss treaties, the minimum annual premium is recorded as written as of the date of the treaty. These amounts are based on reports received from ceding companies, supplemented by our own estimates of premiums for which ceding company reports have not been received. Subsequent differences arising on such estimates are recorded in the period they are determined. Unearned premium reserves represent the portion of premiums written that relates to the unexpired terms of contracts in force. Certain of our contracts included provisions that adjust premiums or acquisition expenses

20

based upon the experience under the contracts. Premiums written and earned as well as related acquisition expenses under those contracts are recorded based upon the projected ultimate experience under these contracts.

We also write non-traditional reinsurance business that is intended to provide insurers with risk management solutions that complement traditional reinsurance. Under these contracts, we assume a measured amount of insurance risk in exchange for a specified margin. Coverages may include a combination of sublimits and caps. Examples of such non-traditional business include aggregate stop-loss coverages and financial quota share coverages.

Certain contracts included in our non-traditional reinsurance business, which pursuant to Statement of Financial Accounting Standards ("SFAS") No. 113, "Accounting and Reporting for Reinsurance of Short-Duration and Long-Duration Contracts," issued by the Financial Accounting Standards Board ("FASB"), are deemed, for financial reporting purposes, not to transfer insurance risk, are accounted for using the deposit method of accounting as prescribed in Statement of Position 98-7, "Deposit Accounting: Accounting for Insurance and Reinsurance Contracts That Do Not Transfer Insurance Risk." For those contracts that contain an element of underwriting risk, non-refundable fees are deferred and amortized over the contract period. Such fees are included in our underwriting results. For those contracts that do not transfer an element of underwriting risk, the expected profit is reflected in earnings over the estimated settlement period using the interest method. Such profit is included in investment income.

Under generally accepted accounting principles ("GAAP"), acquisition expenses and other expenses that vary with and are directly related to the acquisition of business related to our underwriting operations are deferred and amortized over the period in which the related premiums are earned. Under statutory accounting principles, underwriting expenses are recognized immediately as premiums are written.

Acquisition expenses consist principally of commissions and brokerage expenses. Other operating expenses also include expenses that vary with and are directly related to the acquisition of business. Acquisition expenses for the insurance segment are reflected net of ceding commissions from third party reinsurers. Deferred acquisition costs are carried at their estimated realizable value based on the related unearned premiums and take into account anticipated losses and loss adjustment expenses, based on historical and current experience, and anticipated investment income.

RESERVES FOR LOSSES AND LOSS ADJUSTMENT EXPENSES

Insurance reserves are inherently subject to uncertainty. The reserves for losses and loss adjustment expenses represent estimates involving actuarial and statistical projections at a given point in time of our expectations of the ultimate settlement and administration costs of losses incurred and it is likely that the ultimate liability may exceed or be less than such estimates. We utilize actuarial models as well as available historical insurance and reinsurance industry loss development patterns to assist in the establishment of appropriate loss reserves. Even actuarially sound methods can lead to subsequent adjustments to reserves that are both significant and irregular due to the nature of the risks written, potentially by a material amount. If our reserves for losses and loss adjustment expenses are determined to be inadequate, we will be required to increase the reserves with a corresponding reduction in net income in the period in which the deficiency is determined.

For reinsurance assumed, the reserves are based on reports received from ceding companies, supplemented by our estimates of reserves for which ceding company reports have not been received, and our own historical experience. For our insurance operations, claims personnel determine whether to establish a case reserve for the estimated amount of the ultimate settlement, if any. The estimate reflects the judgment of claims personnel based on general corporate reserving practices, and on the experience and knowledge of such personnel regarding the nature and value of the specific type of claim and, where appropriate, advice of counsel. Our insurance operations also contract with a number of outside third party administrators and managing general agents in the claims process, and the work of such parties is reviewed by our claims personnel. Reserves are also established to provide for the estimated expense of settling claims, including legal and other fees and the general expenses of administering the claims adjustment process. Periodically, adjustments to the case reserves may be made as additional information regarding the claims is reported or payments are made.

In accordance with industry practice, we maintain incurred but not reported ("IBNR") reserves. Such reserves are established to provide for future case reserves and loss payments on incurred claims which have not

21

yet been reported to an insurer or reinsurer. In calculating its IBNR reserves, we use generally accepted actuarial reserving techniques that take into account quantitative loss experience data, together, where appropriate, with qualitative factors. IBNR reserves are based on loss experience of the company and the industry, and are grouped both by class of business and by accident year. IBNR reserves are also adjusted to take into account certain factors such as changes in the volume of business written, reinsurance contract terms and conditions, the mix of business, claims processing and inflation that can be expected to affect our liability for losses over time.

Even though most insurance contracts have policy limits, the nature of property and casualty insurance and reinsurance is that losses can exceed policy limits for a variety of reasons and could very significantly exceed the premiums received on the underlying policies. We will attempt to limit our risk of loss through reinsurance and may also use retrocessional arrangements. The availability and cost of reinsurance and retrocessional protection is subject to market conditions, which are beyond our control.

In establishing the reserves for losses and loss adjustment expenses, we have made various assumptions relating to the pricing of our reinsurance contracts and insurance policies, available historical industry experience and current industry conditions. Our reserving process reflects that there is a possibility that the assumptions made could prove to be inaccurate due to several factors primarily relating to our start-up nature, including the fact that very limited historical information has been reported to us through June 30, 2002, although there can be no assurances that our reserves will prove to be adequate. It is possible that claims in respect of events that have occurred could exceed our reserves and have a material adverse effect on our results of operations in a particular period or our financial condition in general.

COLLECTION OF INSURANCE-RELATED BALANCES

We maintain allowances for doubtful accounts for probable losses resulting from our inability to collect premiums. We are subject to credit risk with respect to our reinsurance ceded because the ceding of risk to reinsurers does not relieve us of our liability to the clients or companies we insure. If the financial condition of our reinsurers or retrocessionaires were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

We are also subject to credit risk from our alternative market products, such as rent-a-captive risk-sharing programs which allow a client to retain a significant portion of its loss exposure without the administrative costs and capital commitment required to establish and operate its own captive. In certain of these programs, we participate in the operating results by providing excess reinsurance coverage and earn commissions and management fees. We also write program business on a risk-sharing basis with agents or brokers which is achieved with a contingent commission structure based upon the program underwriting results. While we attempt to obtain sufficient collateral from managing general agents or other clients to guarantee their projected financial obligations to us, there is no guarantee that such collateral will be sufficient to secure their actual ultimate obligations.

VALUATION ALLOWANCE

We record a valuation allowance to reduce certain of our deferred tax assets to the amount that is more likely than not to be realized. While we have considered future taxable income and feasible tax planning strategies in assessing the need for a valuation allowance, in the event we were to determine that we would not be able to realize all or part of our deferred tax assets in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made. In addition, if we subsequently assessed that the valuation allowance was no longer needed, then a benefit would be recorded to income in the period such determination was made.

INVESTMENTS

We currently classify all of our publicly traded fixed maturity, short-term investments and equity securities as "available for sale" and, accordingly, they are carried at estimated fair value. The fair value of publicly traded fixed maturity securities and publicly traded equity securities is estimated using quoted market prices or dealer quotes. Investments included in our private portfolio include securities issued by privately held companies that are generally restricted as to resale or are otherwise illiquid and do not have readily ascertainable market values. Our investments in privately held equity securities, other than those carried under the equity method of

22

accounting, are carried at estimated fair value. Fair value is initially considered to be equal to the cost of such investment until the investments are revalued based on substantive events or other factors which could indicate a diminution or appreciation in value. In accordance with Accounting Principles Board ("APB") Opinion No. 18 for privately held equity investments accounted for under the equity method, we review the facts and circumstances surrounding our ownership for each investment to determine the appropriate accounting method for such investment and we record our percentage share of the investee company's net income. The risk of investing in such securities is generally greater than the risk of investing in securities of widely held, publicly traded companies. Lack of a secondary market and resale restrictions may result in an inability by us to sell a security at a price that would otherwise be obtainable if such restrictions did not exist and may substantially delay the sale of a security we seek to sell.

In accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities," we review our investments to determine whether a decline in fair value below the amortized cost basis is other than temporary. If such decline in fair value is judged to be other than temporary, we would write down the investment to fair value as a new cost basis and the amount of the write-down would be charged to income as a realized loss. The new cost basis would not be changed for subsequent recoveries in fair value.

STOCK ISSUED TO EMPLOYEES

We follow APB Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations in accounting for employee stock options. Accordingly, under APB No. 25, compensation expense for stock option grants is recognized only to the extent that the fair value of the underlying stock exceeds the exercise price of the option at the measurement date. In addition, under APB No. 25, we do not recognize compensation expense for stock issued to employees under our stock purchase plan. See "Other Revenue and Expenses--Non Cash Compensation."

For restricted shares granted, we record deferred compensation equal to the market value of the shares at the measurement date, which is amortized and charged to income as non-cash compensation over the vesting period. These restricted shares are recorded as outstanding upon issuance (regardless of any vesting period). See "Other Revenue and Expenses--Non-Cash Compensation."

RECENT ACCOUNTING PRONOUNCEMENTS

In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which we adopted on January 1, 2002. SFAS No. 144 addresses the accounting and reporting for impairment of long-lived assets to be held and used, as well as long-lived assets to be disposed of. The standard requires that long-lived assets to be held and used will be written down to fair value when they are considered impaired. Long-lived assets to be disposed of are to be carried at the lower of carrying amount or fair value less estimated cost to sell. SFAS No. 144 also broadens the presentation of discontinued operations on the income statement to include a component of an entity (rather than a segment of a business). The adoption of this standard did not have a material effect on our financial position at June 30, 2002 or results of operations for the six months ended June 30, 2002.

In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146 will be applied prospectively to exit or disposal activities initiated after December 31, 2002 and requires companies to recognize costs associated with exit activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. We are currently evaluating this standard.

RESULTS OF OPERATIONS

Comparisons of our 2002 and 2001 results of operations to each other and to prior year periods are not relevant due to the changes in our business during 2001 and 2002, including (1) our 2001 acquisition activity, (2) our new underwriting initiatives in insurance and reinsurance and (3) the capital infusions in November 2001 and April 2002. In addition, because of these factors, as well as the other factors described in this report, including those noted below under the caption "--Cautionary Note Regarding Forward-Looking Statements" and in the section entitled "Risk Factors" included in our Annual Report on Form 10-K for the year ended December 31, 2001, our historical financial results do not provide you with a meaningful expectation of our future results.

The increase in diluted average shares outstanding from 2001 to 2002 was primarily due to the issuance of convertible preference shares and Class A warrants in connection with our capital infusion in November 2001 and the issuance of 7,475,000 common shares in connection with an offering completed by us in April 2002. Pursuant to a post-closing purchase price adjustment mechanism under the subscription agreement entered into in connection with the capital infusion in November 2001 (the "Subscription Agreement"), we issued 875,753 additional Series A convertible preference shares on June 28, 2002. Such issuance did not result in a significant increase in our average shares for the three or six month periods ended June 30, 2002.

Under SFAS No. 128, "Earnings Per Share," upon the satisfaction of all the conditions necessary for the issuance of contingent shares, such shares are required to be included in the denominator of the diluted earnings per share calculation as of the beginning of the interim period in which the conditions are satisfied. If the contingency provisions with respect to our contingently issuable common shares described below under the caption "--Potential Adjustments to Book Value Per Share" had been met as of January 1, 2002, pro forma diluted weighted average shares outstanding for the three and six month periods ended June 30, 2002 would have been 62,601,966 shares and 58,715,535 shares, respectively, and pro forma diluted net income per share for the three and six month periods ended June 30, 2002 would have been $0.31 and $0.39, respectively. Under SFAS No. 128, once such shares have been issued following the satisfaction of such conditions, those shares are required to be included in the computation of basic earnings per share.

After-tax operating income is defined as net income, excluding net realized investment gains or losses on investment sales, non-cash compensation charges, foreign exchange gains or losses and equity in net income or loss of investees. As set forth in the above table, for the three months ended June 30, 2002, after-tax operating income was $15.5 million, or $0.27 per share, and for the six months ended June 30, 2002, after-tax operating income was $23.9 million, or $0.43 per share. Net income for the 2002 second quarter was $19.2 million, or $0.33 per share, and for the six months ended June 30, 2002, net income was $23.2 million, or $0.42 per share.

Operating income for the 2002 second quarter and six months ended June 30, 2002 reflect the underwriting results of our rinsurance and insurance segments, as disused below.

SEGMENT INFORMATION

We classify our businesses into two underwriting segments, reinsurance and insurance. For a description of our underwriting segments, please refer to note 6 under the caption "Segment Information" of the notes accompanying our consolidated financial statements.

REINSURANCE SEGMENT

OPERATING RESULTS. The following table sets forth an analysis of the underwriting results for the reinsurance segment for the three and six month periods ended June 30, 2002.

GROSS AND NET PREMIUMS WRITTEN. During the period from January 1 to July 31, 2002, our reinsurance subsidiaries have entered into reinsurance treaties and other reinsurance arrangements that are expected to provide approximately $800 million of annualized net reinsurance premiums, a substantial portion of which will be recorded in calendar year 2002. Approximately 67% of the annualized premiums written were generated from pro rata contracts and 33% were derived from excess of loss treaties. The quarterly and year-to-date net premiums written differs from the annualized net reinsurance premiums due to the timing of recording premiums for contracts written on a pro rata and excess of loss basis. A significant portion of amounts included as premiums receivable, which represent estimated premiums, net of commissions, are not yet due based on the terms of the underlying contracts.

We are currently retaining substantially all of our reinsurance premiums written. We may purchase reinsurance on both a facultative and treaty basis primarily to reduce net liability on individual risks and, if deemed necessary, to reduce our exposure to catastrophic losses.

Set forth below is summary information regarding net premiums written produced by geographic location and by line of business for the reinsurance segment for the three and six month periods ended June 30, 2002:

(1) Reflects $18.2 million and $37.0 million of net premiums written, respectively, for the three month and six month periods ended June 30, 2002 assumed by the reinsurance segment from the insurance segment.

NET PREMIUMS EARNED. Reinsurance premiums written are recognized as earned on a pro rata basis over the terms of the related reinsurance contracts. Unearned premiums represent the portion of premiums written which is applicable to the unexpired terms of policies in force. When a company is growing rapidly, there will be a significant difference

26

between written and earned premiums. For the six months ended June 30, 2002, approximately 34% of the reinsurance segment net premiums written were earned.

LOSSES AND LOSS ADJUSTMENT EXPENSES. Losses and loss adjustment expenses incurred for the three and six month periods ended June 30, 2002 were 69.7% and 71.1%, respectively, of net premiums earned. For a discussion of the reserves for losses and loss adjustment expenses, please refer to the section above entitled "Critical Accounting Policies, Estimates and Recent Accounting Pronouncements - Reserves for Losses and Loss Adjustment Expenses."

UNDERWRITING EXPENSES. For the three and six month periods ended June 30, 2002, acquisition expenses were 16.8% and 15.5%, respectively, of net premiums earned. As a percentage of net premiums earned, acquisition expenses for the 2002 second quarter are higher compared to the six month period due primarily to an increase in the percentage of pro rata business earned during the 2002 second quarter. Typically, pro rata business is written at a higher expense ratio and lower loss ratio than excess of loss business. For the three and six month periods ended June 30, 2002, other operating expenses were 2.7% and 4.0%, respectively, of net premiums earned.

(1) Reflects $18.2 million and $37.0 million of net premiums written, respectively, for the three month and six month periods ended June 30, 2002 assumed by the reinsurance segment from the insurance segment.

GROSS AND NET PREMIUMS WRITTEN. Our insurance segment commenced writing business in a number of specialty lines in the 2002 second quarter. We expect that the amount of premiums written will continue to increase in the remainder of 2002 as this operation continues to build its infrastructure and increase its participation in the insurance marketplace.

LOSSES AND LOSS ADJUSTMENT EXPENSES. Losses and loss adjustment expenses incurred for the three and six month periods ended June 30, 2002 were 77.1% and 78.4%, respectively, of net premiums earned. For a discussion of the reserves for losses and loss adjustment expenses, please refer to the section above entitled "Critical Accounting Policies, Estimates and Recent Accounting Pronouncements - Reserves for Losses and Loss Adjustment Expenses."

UNDERWRITING EXPENSES. The acquisition expense ratios for the three month and six month periods ended June 30, 2002 were calculated net of certain policy-related fee income, which is earned primarily by American Independent, and resulted in expense ratios of (7.2%) and (8.1%), respectively. Operating expenses included "start-up" expenses of $2.1 million and $3.7 million, respectively, for the three and six month periods ended June 30, 2002. In addition, such periods also include a charge of $1.1 million recorded during the second quarter of 2002 as a result of the establishment of a reserve related to a receivable from a managing general agent. We expect that we will incur a significant amount of additional costs in 2002 in connection with the continued expansion of our insurance operations.

OTHER REVENUE AND EXPENSES

NET INVESTMENT INCOME

The increase in net investment income was due to the significant increase in our invested assets resulting from (i) the capital infusion completed in November 2001, (ii) the proceeds received from the public offering of our common shares in April 2002 and (iii) cash flow from operations. The pre-tax investment yields on our fixed income securities for the three and six month periods ended June 30, 2002 were 4.1% and 3.6%, respectively.

CORPORATE EXPENSES AND OTHER FEE INCOME

Corporate expenses represent certain holding company and infrastructure costs necessary to support our growing worldwide reinsurance and insurance operations. Other fee income represents revenues provided by our non-underwriting operations.

NET REALIZED INVESTMENT GAINS (LOSSES)

For the three and six month periods ended June 30, 2002 and 2001, our sources of net realized investment gains (losses) were as follows:

                                             ================     ================    ===============     ==============

The net realized gains of $6.2 million for the three and six month periods ended June 30, 2002 on our privately held securities resulted primarily from the disposition of our investment in The ARC Group, LLC in April 2002 and the sale of certain underlying holdings included in our Trident II, L.P. interest. The net realized losses of $3.7 million and $4.5 million for the three and six month periods ended June 30, 2002, respectively, on our fixed maturity portfolio resulted from the sale of certain securities to reduce credit exposure, and sales related to rebalancing the portfolio which is managed on a total return basis.

NON-CASH COMPENSATION

During 2001 and 2002, we made certain grants (primarily of restricted shares) to new employees and the chairman of our board of directors under our stock incentive plans and other arrangements. These grants were made primarily in connection with our new underwriting initiative and resulted in a pre-tax provision for non-cash compensation of $8.6 million and $12.8 million, respectively, for the three and six month periods ended June 30, 2002. As a result of the grants referred to above, we expect to record a significant increase in non-cash compensation in the remainder of 2002 as compared to 2001.

As provided under SFAS No. 123, "Accounting for Stock-Based Compensation," we have elected to continue to account for stock-based compensation in accordance with APB No. 25. If we had elected to expense employee stock options under the fair value method of SFAS No. 123, our basic net income per share for the three and six months ended June 30, 2002 would have been reduced by $0.20 and $0.53, respectively, and our diluted net income per share would have been reduced by $0.07 and $0.16, respectively.

NET FOREIGN EXCHANGE GAINS

In the 2002 second quarter, net foreign exchange gains of $3,352,000 consisted of an unrealized gain of $3,263,000 and a realized gain of $89,000. Net foreign exchange gains for the six months ended June 30, 2002 of $3,244,000 consisted of an unrealized gain of $3,263,000 and a realized loss of $19,000. The net unrealized gain resulted from the translation of foreign denominated monetary assets and liabilities at June 30, 2002 as required by GAAP. Under GAAP, accounts that are classified as monetary assets and liabilities, such as premiums receivable and the reserve for losses and loss adjustment expenses, are revalued at each balance sheet

29

date. Accounts that are classified as non-monetary are not revalued. Pursuant to GAAP, the unearned premium reserve is classified as non-monetary and, accordingly, was not revalued at June 30, 2002. If the unearned premium reserve was considered a monetary asset under GAAP, the unrealized foreign exchange gain would have been reduced by $3.3 million for the three and six month periods ended June 30, 2002.

Foreign exchange gains and losses vary with fluctuations in currency rates. As such, these gains and losses could add significant volatility to our net income in future periods.

EQUITY IN NET INCOME OF INVESTEES

At June 30, 2002, we held seven investments in privately held securities, including four investments held under the equity method of accounting. Under the equity method, we record a proportionate share of the net income or loss based on our ownership percentage. Of the $1.6 million of pre-tax equity in net income of investees for the six months ended June 30, 2002, approximately $557,000 was generated from our investment in ARC, which was sold in April 2002.

INCOME TAXES

During the 2002 second quarter, we reversed a $7.4 million valuation allowance on certain of our deferred tax assets. The valuation allowance reversal was based on our recently completed restructuring of our U.S.-based insurance underwriting operations and our business plan.

For the six months ended June 30, 2002, our income tax provision resulted in an effective tax rate of 14.5%, excluding the reversal of a $7.4 million valuation allowance. Our remaining valuation allowance at June 30, 2002 is $2.1 million. Our effective tax rate will fluctuate based on the relative amounts of our U.S.-sourced income and our worldwide income. The effective tax rate on our net operating income for the six months ended June 30, 2002 was 5.9%, which was lower than our overall effective tax rate due to the relative amounts of our U.S.-sourced income and our worldwide income. See note 10 under the caption "Income Taxes" of the notes accompanying our consolidated financial statements.

ACGL will be subject to U.S. federal income tax only to the extent that it derives U.S. source income that is subject to U.S. withholding tax or income that is effectively connected with the conduct of a trade or business within the U.S. and is not exempt from U.S. tax under an applicable income tax treaty with the U.S. ACGL will be subject to a withholding tax on dividends from U.S. investments and interest from certain U.S. taxpayers. ACGL does not consider itself to be engaged in a trade or business within the U.S. and, consequently, does not expect to be subject to direct U.S. income taxation. However, because there is uncertainty as to the activities which constitute being engaged in a trade or business within the United States, there can be no assurances that the U.S. Internal Revenue Service will not contend successfully that ACGL or its non-U.S. subsidiaries are engaged in a trade or business in the United States. If ACGL or any of its non-U.S. subsidiaries were subject to U.S. income tax, ACGL's shareholders' equity and earnings could be materially adversely affected. ACGL's U.S. subsidiaries are subject to U.S. income taxes on their worldwide income.

ACGL changed its legal domicile from the United States to Bermuda in November 2000. Legislation has been introduced which (if enacted) could eliminate the tax benefits available to companies that have changed their legal domiciles to Bermuda, and such legislation may apply to ACGL. In addition, some U.S. insurance companies have been lobbying Congress to pass legislation intended to eliminate certain perceived tax advantages of U.S. insurance companies with Bermuda affiliates resulting principally from reinsurance between or among U.S. insurance companies and their Bermuda affiliates. This legislation, if passed, and other changes in U.S. tax laws, regulations and interpretations thereof to address these issues could materially adversely affect us.

LIQUIDITY AND CAPITAL RESOURCES

ACGL is a holding company whose assets primarily consist of the shares in its subsidiaries. Generally, we depend on our available cash resources, liquid investments and dividends or other distributions from our subsidiaries to make payments, including the payment of operating expenses we may incur and for any dividends our board of directors may determine. ACGL does not currently intend to declare any dividends.

30

Pursuant to a shareholders agreement that we entered into in connection with the November 2001 capital infusion, we have agreed not to declare any dividend or make any other distribution on our common shares, and not to repurchase any common shares, until we have repurchased from the Warburg Pincus funds, the Hellman & Friedman funds and the other holders of our preference shares, pro rata, on the basis of the amount of each of these shareholders' investment in us at the time of such repurchase, preference shares having an aggregate value of $250.0 million, at a per share price acceptable to these shareholders.

The ability of our regulated insurance and reinsurance subsidiaries to pay dividends or make distributions is dependent on their ability to meet applicable regulatory standards. Arch Re Bermuda is prohibited from declaring or paying in any financial year dividends of more than 25% of its total statutory capital and surplus (as shown on its previous financial year's statutory balance sheet) unless it files, at least seven days before payment of such dividends, with the Bermuda Monetary Authority an affidavit stating that it will continue to meet the required margins. In addition, Arch Re Bermuda is prohibited, without prior approval of the Bermuda Monetary Authority, from reducing by 15% or more its total statutory capital, as set out in its previous year's financial statements. At December 31, 2001 and June 30, 2002, Arch Re Bermuda had statutory capital and surplus (as determined under Bermuda law) of $508 million and $667 million, respectively. As of December 31, 2001, our U.S. insurance and reinsurance subsidiaries may not pay any significant dividends or distributions during 2002 without prior regulatory approval. In addition, the ability of our insurance and reinsurance subsidiaries to pay dividends could be constrained by our dependence on financial strength ratings from independent rating agencies. Our ratings from these agencies depend to a large extent on the capitalization levels of our insurance and reinsurance subsidiaries.

Our aggregate invested assets, including cash and short-term investments, totaled $1.3 billion and $1.0 billion at June 30, 2002 and December 31, 2001, respectively. As of June 30, 2002, our readily available cash, short-term investments and marketable securities, excluding amounts held by our regulated insurance and reinsurance subsidiaries, totaled $41.2 million. Such amount consisted of $16.5 million of cash and short-term investments and $24.7 million of fixed maturity investments. As of that date, investments that are restricted or generally unavailable for liquidity purposes (other than our ownership interests in our subsidiaries and the invested assets of our regulated insurance and reinsurance subsidiaries) included $24.9 million of privately held securities. In addition, at June 30, 2002, we had investment commitments relating to our privately held investments of approximately $3.6 million.

Cash flows on a consolidated basis are provided by premiums collected, fee income, investment income and collected reinsurance recoverables, offset by losses and loss adjustment expense payments, reinsurance premiums payable and operating costs. Consolidated cash flows provided by (used for) operating activities for the six months ended June 30, 2002 and 2001 were approximately $113.7 million and ($292,000), respectively.

Our expanded underwriting activities will initially be supported by our capital, and we expect that our other operational needs for the foreseeable future will be met by our balance of cash and short-term investments, as well as by funds generated from premiums and investment income and proceeds on the sale or maturity of our investments.

We have an effective shelf registration statement with the Securities and Exchange Commission. It permits us to issue various types of securities, including unsecured debt securities, preference shares and common shares, from time to time, up to an aggregate of $500 million. During April, we issued 7,475,000 of our common shares and received net proceeds of approximately $179 million, net of transaction costs. The net proceeds of the offering were principally used to increase the surplus of our insurance and reinsurance subsidiaries. The unused portion of our shelf registration is approximately $309 million following the offering in April. Any additional issuance of common shares by us could have the effect of diluting our earnings and our book value per share.

In addition, the Warburg Pincus funds and the Hellman & Friedman funds together control a majority of our voting power on a fully-diluted basis and have the right to nominate a majority of directors to our board under the shareholders agreement entered into in connection with the November 2001 capital infusion. The shareholders agreement also provides that we cannot engage in transactions including mergers and acquisitions and transactions in excess of certain amounts, without the consent of a designee of the Warburg Pincus funds and a designee of the Hellman & Friedman funds. These provisions could have an effect on the operation of our business and, to the extent these provisions discourage takeover attempts, they could deprive our shareholders of opportunities to realize takeover premiums for their shares or could depress the market price of our common shares. By reason of their ownership and the shareholders agreement, the Warburg Pincus funds and the Hellman & Friedman funds are able to strongly influence or effectively control actions to be taken by us. The

31

interests of these shareholders may differ materially from the interests of the holders of our common shares, and these shareholders could take actions that are not in the interests of the holders of our common shares.

CERTAIN MATTERS WHICH MAY MATERIALLY AFFECT OUR RESULTS OF OPERATIONS AND/OR FINANCIAL CONDITION

RESERVES FOR LOSSES AND LOSS ADJUSTMENT EXPENSES

We establish reserves for losses and loss adjustment expenses which represent estimates involving actuarial and statistical projections, at a given point in time, of our expectations of the ultimate settlement and administration costs of losses incurred. We utilize actuarial models as well as available historical insurance industry loss development patterns to assist in the establishment of appropriate loss reserves. Actual losses and loss adjustment expenses paid may deviate, perhaps substantially, from the reserve estimates reflected in our financial statements. See "--Critical Accounting Polices, Estimates and Recent Accounting Pronouncements - Reserves for Losses and Loss Adjustment Expenses."

REINSURANCE PROTECTION AND RECOVERABLES

For purposes of limiting our risk of loss, we reinsure a portion of our exposures, paying to reinsurers a part of the premiums received on the policies we write, and we may also use retrocessional protection. For the three and six month periods ended June 30, 2002, ceded premiums written represented approximately 12% and 10%, respectively, of gross written premium. In 2002, we are retaining a greater amount of our insurance premiums written as compared to 2001 as a result of the new underwriting initiative and our improved financial position.

The availability and cost of reinsurance and retrocessional protection is subject to market conditions, which are beyond our control. Currently, the market for these arrangements is experiencing high demand for various products and it is not certain that we will be able to obtain adequate protection at cost effective levels. As a result of such market conditions and other factors, we may not be able successfully to alleviate risk through reinsurance and retrocessional arrangements. Further, we are subject to credit risk with respect to our reinsurance and retrocessions because the ceding of risk to reinsurers and retrocessionaires does not relieve us of our liability to the clients or companies we insure or reinsure. Our failure to establish adequate reinsurance or retrocessional arrangements or the failure of our existing reinsurance or retrocessional arrangements to protect us from overly concentrated risk exposure could adversely affect our financial condition and results of operations. We monitor the financial condition of our reinsurers and attempt to place coverages only with substantial, financially sound carriers. At June 30, 2002, approximately 91% of our reinsurance recoverables were due from carriers which had an A.M. Best rating of "A-" or better. We had no amounts recoverable from a single entity or group of entities that exceeded 5% of our total shareholders' equity. At June 30, 2002, amounts due from the following reinsurers represented approximately 47% of our reinsurance recoverables (with A.M. Best ratings in parentheses):
Hartford Fire Insurance Company ("A+"); Folksamerica Reinsurance Company ("A-"); GMAC Insurance Group ("A+"); Swiss Re America Group ("A++"); Odyssey Reinsurance Corporation ("A"); GE Reinsurance Corporation ("A++"); PMA Capital Insurance Company ("A u"; under review by A.M. Best with negative implications); and St. Paul Fire and Marine Insurance Company ("A"). We also have reinsurance recoverables from Lloyd's of London syndicates (group rating of "A-") aggregating approximately 10% of our total. In addition, in connection with our acquisition of Arch Specialty in February 2002, the seller, Sentry Insurance a Mutual Company, which has an A.M. Best rating of "A+" (Superior), agreed to reinsure or otherwise assume all liabilities arising out of Arch Specialty's business prior to the closing of the acquisition. The amount of recoverables from Sentry under such arrangements represents approximately 25% of our total recoverables.

NATURAL AND MAN-MADE CATASTROPHIC EVENTS

We have large aggregate exposures to natural and man-made catastrophic events. Catastrophes can be caused by various events, including but not limited to hurricanes, floods, windstorms, earthquakes, hailstorms, explosions, severe winter weather and fires, and we may have losses which may result from acts of war or acts of terrorism and political instability. Catastrophes can also cause losses in non-property lines of business such as workers' compensation or general liability. In addition to the nature of property business, we believe that economic and geographic trends affecting insured property, including inflation, property value appreciation and geographic concentration tend to generally increase the size of losses from catastrophic events over time. Therefore, claims for natural and man-made catastrophic events could expose us to large losses and cause

32

substantial volatility in our results of operations, which could cause the value of our common shares to fluctuate widely.

We have substantial exposure to unexpected, large losses resulting from future man-made catastrophic events, such as acts of war, acts of terrorism and political instability. These risks are inherently unpredictable and recent events may lead to increased frequency and severity of losses. It is difficult to predict the timing of such events with statistical certainty or estimate the amount of loss any given occurrence will generate. It is not possible to eliminate completely our exposure to unforecasted or unpredictable events, and to the extent that losses from such risks occur, our financial condition and results of operations could be materially adversely affected.

We specifically insure and reinsure risks resulting from terrorism. Although we may attempt to exclude losses from terrorism and certain other similar risks from some coverages written by us, we may not be successful in doing so. Moreover, irrespective of the clarity and inclusiveness of policy language, there can be no assurance that a result-oriented court or arbitration panel favoring the insured or ceding company will enforce the language as written; such a tribunal may adopt a strained interpretation of the policy language, invoke public policy to limit enforceability of policy language, ignore policy language, make factual findings unwarranted by the evidence or otherwise seek to justify a ruling adverse to us.

For our catastrophe exposed reinsurance business, we seek to limit the amount of exposure we will assume from any one reinsured and the amount of the exposure to catastrophe losses in any geographic zone. In our reinsurance business, we monitor our exposure to catastrophic events, including earthquake, wind and specific terrorism exposures, and continuously reevaluate the estimated probable maximum pre-tax loss for such exposures. With respect to our reinsurance business, our estimated probable maximum pre-tax loss is determined through the use of modeling techniques, but such estimate does not represent our total potential loss for such exposures. In our reinsurance business, we seek to limit the probable maximum pre-tax loss to a percentage of our total shareholders' equity for severe catastrophic events. Currently, for our reinsurance business, we generally seek to limit the probable maximum pre-tax loss to approximately 25% of total shareholders' equity for severe catastrophic events that could be expected to occur once in every 250 years, which 25% does not include, for such purposes, business assumed directly from our insurance subsidiaries. There can be no assurances that we will not suffer pre-tax losses greater than 25% of our total shareholders' equity from a catastrophic event due to several factors, including the inherent uncertainties in estimating the frequency and severity of such events and the margin of error in making such determinations resulting from potential inaccuracies in the data provided by clients and brokers, the modeling techniques and the application of such techniques. In addition, depending on business opportunities and the mix of business that may comprise our reinsurance portfolio, we may seek to limit the probable maximum pre-tax loss to a higher percentage of our total shareholders' equity for our catastrophe exposed reinsurance business.

Further, for our insurance business, which began operating in its new specialty areas of focus in the 2002 second quarter, we also intend to monitor and limit the amount of our exposure to catastrophic losses and, in that connection, may seek to purchase catastrophe reinsurance protection. The availability and cost of such reinsurance protection is subject to market conditions, which are beyond our control. As a result of market conditions and other factors, we may not be successful in obtaining such protection. See "--Reinsurance Protection and Recoverables" above.

FOREIGN CURRENCY EXCHANGE RATE FLUCTUATION

We write business on a worldwide basis, and our results of operations may be affected by fluctuations in the value of currencies other than the U.S. dollar. Changes in foreign currency exchange rates can reduce our revenues and increase our liabilities and costs, as measured in the dollar as our functional currency. We have not attempted and currently do not expect to attempt to reduce our exposure to these exchange rate risks by using hedging transactions. We may therefore suffer losses solely as a result of exchange rate fluctuations.

MANAGEMENT AND OPERATIONS

As a relatively new insurance and reinsurance company, our success will depend on our ability to integrate new management and operating personnel and to establish and maintain operating procedures and internal controls to effectively support our business and our regulatory and reporting requirements, and no assurances can be given as to the success of these endeavors.

33

CONTINGENCIES RELATING TO THE SALE OF PRIOR REINSURANCE OPERATIONS

See note 5 under the caption "Contingencies Relating to the Sale of Prior Reinsurance Operations" of the notes accompanying our consolidated financial statements.

RESTRUCTURING OF U.S.-BASED INSURANCE OPERATIONS

In April 2002, we completed a restructuring of our U.S. insurance subsidiaries after receiving all applicable regulatory approvals. As a result of the restructuring, the statutory capital of Arch Re U.S. was increased to approximately $350 million (as determined under U.S. statutory accounting policies) and Arch Re U.S. has become the parent of our U.S.-based insurance group. The names of our U.S.-based insurers were changed as follows: First American Insurance Company was renamed Arch Insurance Company; Rock River Insurance Company was renamed Arch Specialty Insurance Company; and Cross River Insurance Company was renamed Arch Excess & Surplus Insurance Company. The name changes have been approved by the companies' respective states of domicile; however, the name change approvals have not yet been obtained from all the other states.

INDUSTRY; RATINGS

We operate in a highly competitive environment, and since the September 11, 2001 events, new capital has entered the market. These factors may mitigate the benefits that the financial markets may perceive for the property and casualty insurance industry, and we cannot offer any assurances that we will be able to compete successfully in our industry or that the intensity of competition in our industry will not erode profitability for insurance and reinsurance companies generally, including us. In addition, we can offer no assurances that we will participate at all or to the same extent as more established or other companies in any price increases or increased profitability in our industry. If we do not share in such price increases or increased profitability, our financial condition and results of operations could be materially adversely affected.

Financial strength and claims paying ratings from third party rating agencies are instrumental in establishing the competitive positions of companies in our industry. Periodically, rating agencies evaluate us to confirm that we continue to meet their criteria for the ratings assigned to us by them. Our reinsurance subsidiaries, Arch Re U.S. and Arch Re Bermuda, and our insurance subsidiaries, Arch Insurance and Arch Specialty, each currently have financial strength ratings of "A-" (Excellent) from A.M. Best. Arch E&S currently is rated "NR-2" (Insufficient Size and/or Operating Experience) from A.M. Best and American Independent has a financial strength rating of "C++" (Marginal) from
A.M. Best. We do not believe that American Independent's non-standard automobile business is particularly ratings sensitive because its insureds purchase insurance primarily to satisfy state and local insurance and financial reporting requirements.

Recently, rating agencies have been coming under increasing pressure as a result of high-profile corporate bankruptcies and may, as a result, increase their scrutiny of rated companies, revise their rating policies or take other action. We can offer no assurances that our ratings will remain at their current levels. A ratings downgrade, or the potential for such a downgrade, could adversely affect both our relationships with agents, brokers, wholesalers and other distributors of our existing products and services and new sales of our products and services.

CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS

In April 2002, we established a letter of credit facility for up to $200 million with Fleet National Bank. This facility expires April 16, 2003. The principal purpose of this facility is to issue, as required, evergreen standby letters of credit in favor of primary insurance or reinsurance counterparties with which we have entered into reinsurance arrangements. Such letters of credit when issued will be secured by a portion of our investment portfolio. In addition, the letter of credit facility also requires that the net worth of ACGL be at least $750 million and that we maintain certain levels of collateral in order for letters of credit to be issued. At June 30, 2002, we had approximately $31.9 million in outstanding letters of credit. In addition to letters of credit, we have and may establish insurance trusts in the U.S. and Canada to secure our reinsurance amounts payable as required.

It is anticipated that the letter of credit facility will be renewed on expiry, but such renewals are subject to the availability of credit from banks which we utilize. In the event such support is insufficient, we could be required to provide alternative security to cedents. This could take the form of additional insurance trusts supported by our investment portfolio or funds withheld using our cash resources. The value of letters of credit is driven by,

34

among other things, loss development of existing reserves, the payment pattern of such reserves, the further expansion of our business and the loss experience of such business. If we are unable to post security in the form of letters of credit or trust funds when required, our operations could be significantly and negatively affected.

INVESTMENTS

At June 30, 2002, consolidated cash and invested assets totaled approximately $1.3 billion, consisting of $213.4 million of cash and short-term investments, $1.1 billion of publicly traded fixed maturity investments and $31.6 million of privately held securities. Our fixed income portfolio had an average Standard & Poor's Corporation quality rating of "AA-" and an average duration of 2.8 years at June 30, 2002.

The following table provides information on the composition of our fixed maturity investments at June 30, 2002:

As part of our investment strategy, we seek to establish a level of cash and highly liquid short-term and intermediate-term securities which, combined with expected cash flow, is believed by us to be adequate to meet our foreseeable payment obligations. Our investment portfolio is managed on a total return basis. The total return approach may result in realized gains or losses in any given period as the portfolio is adjusted to reflect perceived changes in relative value.

Our current investment guidelines stress preservation of capital, market liquidity and diversification of risk. To achieve this objective, our current fixed income investment guidelines provide for an average credit quality of "Aa3" and "AA-" as measured by Moody's Investors Services and Standard & Poor's, respectively. Notwithstanding the foregoing, our investments are subject to market-wide risks and fluctuations, as well as to risks inherent in particular securities.

35

At June 30, 2002, our private equity portfolio consisted of seven investments, with additional investment portfolio commitments in an aggregate amount of approximately $3.6 million. We do not currently intend to make any significant investments in privately held securities over and above our current commitments. See note 8, "Investment Information," of the notes accompanying our consolidated financial statements.

BOOK VALUE PER SHARE

On a diluted basis, the per share book value at June 30, 2002 was $20.27, compared with $19.59 at December 31, 2001. The increase in diluted book value per share was primarily attributable to the net effects of issuing 7,475,000 common shares at $25.50 per share in the stock offering which was completed in April 2002, and an increase in unrealized appreciation of investments of $10.9 million. These increases were partially offset by the effects of the issuance on June 28, 2002 of 875,753 additional Series A convertible preference shares pursuant to a post-closing purchase price adjustment mechanism under the Subscription Agreement. The diluted per share book value reflects our outstanding convertible preference shares and Class A warrants, but does not take into account certain potential adjustments. If such potential adjustments were triggered, the diluted pro forma book value at June 30, 2002 would have been reduced by $0.91 per share. The calculation of our book value per share amounts and the potential adjustments to book value per share are described below.

CALCULATION OF BOOK VALUE PER SHARE

The following actual book value per share calculations are based on shareholders' equity of $1,246,047 at June 30, 2002 (unaudited) and $1,020,369 at December 31, 2001 (audited).

(1) Book value per common share at June 30, 2002 and December 31, 2001 was determined by dividing (i) the difference between total shareholders' equity and the aggregate liquidation preference of the Series A convertible preference shares of $767.8 million and $749.4 million, respectively, by (ii) the number of common shares outstanding.

(2) Includes preference shares that were issued on November 20, 2001 in exchange for $763.1 million of cash. The number of preference shares issued was based on the estimated per share price of $21.38. The estimated per share price was based on (i) total shareholders' equity as of June 30, 2001 (adjusted for certain amounts as described in the Subscription Agreement entered into in connection with the November 2001 capital infusion), divided by (ii) the total number of common shares outstanding as of June 30, 2001, which was 12,863,079. In addition, the amount of preference shares at June 30, 2002 includes 875,753 preference shares that were issued by us on June 28, 2002 pursuant to a post-closing purchase price adjustment mechanism under the Subscription Agreement. Each preference share is convertible at any time and from time to time at the option of the holder thereof into one fully paid and nonassessable common share, subject to possible adjustment.

(3) Includes the net number of common shares that would be issued under the Class A warrants, primarily issued in connection with the capital infusion transaction, calculated using the treasury stock method. Class A warrants to purchase an aggregate of 3,842,450 and 5,401,707 common shares were outstanding as of June 30, 2002 and

36

December 31, 2001, respectively. Class A warrants are immediately exercisable at $20 per share and expire September 19, 2002. In April 2002, 446,608 common shares were issued upon the exercise of 1,559,257 Class A warrants on a cashless basis.

(4) Represents restricted common shares issued in connection with the November 2001 capital infusion transaction. These restricted common shares are included in common shares at June 30, 2002.

POTENTIAL ADJUSTMENTS TO BOOK VALUE PER SHARE

The following are potential adjustments to book value per share at June 30, 2002 and December 31, 2001, excluding the effects of stock options, that could be made if certain future events described below occur.

(1) Amount at December 31, 2001 represents an estimate of the amount of additional Series A convertible preference shares that will be issued to the new investors during the second quarter of 2002 pursuant to a post-closing purchase price adjustment mechanism under the Subscription Agreement. The per share price was based on (i) total shareholders' equity as of June 30, 2001 as set forth on the audited balance sheet, adjusted for certain items as described in the Subscription Agreement, divided by (ii) the total number of common shares outstanding as of June 30, 2001. Consistent with such estimate, 875,753 preference shares were issued to the new investors on June 28, 2002 and are reflected in the amount of preference shares at June 30, 2002.

(2) Represents an estimate of the amount of additional Series A preference shares that would be issued under the Subscription Agreement in the event that on or prior to September 19, 2005 (1) the closing price of our common shares is at least $30 per share for at least 20 out of 30 consecutive trading days or (2) a change in control occurs (either case, a "Triggering Event"). Pursuant to the Subscription Agreement, we have agreed to issue to the new investors additional Series A preference shares such that the audited per share price is adjusted downward by $1.50 per preference share.

(3) Includes the number of common shares that would be issued under the Class B warrants for purposes of calculating diluted book value per share under the treasury stock method. Class B warrants to purchase an aggregate of 150,000 common shares were outstanding as of June 30, 2002 and December 31, 2001 and expire September 19, 2005. Class B warrants are exercisable at $20 per share when (1) the closing price of our common shares is at least $30 per share for at least 20 out of 30 consecutive trading days or (2) a change in control occurs.

Pursuant to the Subscription Agreement, a post-closing purchase price adjustment will be calculated in November 2003 (or such earlier date as agreed upon by us and the investors) based on an adjustment basket. The adjustment basket will be equal to (1) the difference between value realized upon sale and the GAAP book value at the closing of the capital infusion (November 2001) (as adjusted based on a pre-determined growth rate) of agreed upon non-core businesses; plus (2) the difference between GAAP net book value of the insurance balances attributable to our core insurance operations with respect to any policy or contract written or having an effective date prior to November 20, 2001 at the time of the final adjustment and those balances at the closing; minus (3) reductions in book value arising from costs and expenses relating to the transaction provided under

37

the Subscription Agreement, actual losses arising out of breach of representations under the Subscription Agreement and certain other costs and expenses. If the adjustment basket, which will be calculated by our independent auditors, is less than zero, we will issue additional preference shares to the investors based on the decrease in value of the components of the adjustment basket. If the adjustment basket is greater than zero, we are allowed to use cash in an amount based on the increase in value of the components of the adjustment basket to repurchase common shares (other than any common shares issued upon conversion of the preference shares or exercise of the Class A warrants). If the adjustment basket is less than zero and in the event that a Triggering Event occurs, we agreed to issue additional preference shares to the investors as a further adjustment. In addition, on the fourth anniversary of the closing, there will be a calculation of a further adjustment basket based on (1) liabilities owed to Folksamerica (if any) under the Asset Purchase Agreement, dated as of January 10, 2000, between us and Folksamerica, and (2) specified tax and ERISA matters under the Subscription Agreement.

MARKET SENSITIVE INSTRUMENTS AND RISK MANAGEMENT

In accordance with the SEC's Financial Reporting Release No. 48, we performed a sensitivity analysis to determine the effects that market risk exposures could have on the future earnings, fair values or cash flows of our financial instruments as of December 31, 2001. (See section captioned "Management's Discussion and Analysis of Financial Condition and Results of Operations - Market Sensitive Instruments and Risk Management" included in our 2001 Annual Report on Form 10-K.) Market risk represents the risk of changes in the fair value of a financial instrument and is comprised of several components, including liquidity, basis and price risks. At June 30, 2002, there have been no material changes in market risk exposures that affect the quantitative and qualitative disclosures presented as of December 31, 2001.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We, in common with the insurance industry in general, are subject to litigation and arbitration in the normal course of our business. As of June 30, 2002, we were not a party to any material litigation or arbitration other than as a part of the ordinary course of business in relation to claims activity, none of which is expected by management to have a significant adverse effect on our results of operation and financial condition and liquidity.

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

On March 7, 2002, at a special meeting of shareholders, our shareholders approved amendments to bye-laws 45 and 75, and on June 27, 2002, at our annual shareholders meeting, our shareholders approved an amendment to bye-law 20. These amendments were made in connection with the November 2001 capital infusion by investors led by Warburg Pincus investment funds, Hellman & Friedman investment funds and certain members of management. These amendments are described in more detail in our proxy statements for those meetings filed with the Securities and Exchange Commission on January 23, 2002 and June 3, 2002.

BYE-LAW 45

Before the amendment, bye-law 45 limited the voting rights of any person that owned (directly, indirectly or constructively under the Internal Revenue Code (the "Code")) ACGL shares with more than 9.9% of the total voting power of all ACGL shares entitled to vote generally at an election of directors to 9.9% of such voting power. This provision was intended to prevent ACGL from being characterized as a controlled foreign corporation under the Code. Bye-law 45 also limited the rights of any group within the meaning of the Exchange Act of 1934, as amended (the "Exchange Act"), that owned ACGL shares with more than 9.9% of the total voting power of all ACGL shares entitled to vote generally at an election of directors to 9.9% of such voting power.

The amendment to bye-law 45 changed these voting limitations so that the limitation now applies only to votes conferred (directly or indirectly or by attribution) by ACGL shares directly, indirectly or constructively owned (within the meaning of section 958 of the Code) by any U.S. person, as defined in section 7701(a)(30) of the Code. If the votes so conferred on such U.S. person would represent more than 9.9% of the voting power of all ACGL shares entitled to vote generally at an election of directors, the votes so conferred would, in general, be reduced by whatever amount is necessary so that after the reduction the votes so conferred on such U.S. person constitutes 9.9% of the total voting power of all ACGL shares entitled to vote generally at any election of directors.

The amendment allows non-U.S. persons, including the Warburg Pincus investment funds and the Hellman & Friedman investment funds, to have more than 9.9% of the total voting power of ACGL shares. This change resulted in ACGL being characterized as a controlled foreign corporation.

There may be circumstances in which the votes conferred on a U.S. person are reduced to less than 9.9% as a result of the operation of bye-law 45 as amended, because of shares, including shares of the Warburg Pincus investment funds and the Hellman & Friedman investment funds, that may be attributed to that person under the Code.

BYE-LAW 75

Before the amendment, the boards of directors of any of our subsidiaries that are incorporated in Bermuda, and any other subsidiary designated by our board of directors, was required to consist of persons who have been elected by our shareholders either as (1) alternate directors of our board of directors or
(2) designated company directors.

The amendment to bye-law 75 made the provisions of bye-law 75 expressly applicable to subsidiaries incorporated under the laws of the Cayman Islands and Barbados, as well as Bermuda. In addition, the

40

references to alternate directors were deleted, since our shareholders have elected specified individuals to serve as directors of our existing and future Bermuda, Barbados and other non-U.S. subsidiaries, making the concept of alternate directors unnecessary.

BYE-LAW 20

Before the amendment, bye-law 20 provided that special meetings of ACGL's board of directors may be called by the chairman of the board or by the president, or by a majority of the total number of directors of ACGL.

As amended, bye-law 20 provides that a special meeting of the ACGL board of directors may be called by three directors or a majority of the total number of directors (whichever is fewer), in addition to the chairman of the board and the president of ACGL. We were required to submit this amendment for approval by the shareholders under the shareholders agreement with the investors in the capital infusion. Although the Warburg Pincus investment funds and the Hellman & Friedman investment funds are entitled to designate nominees that, in the aggregate, constitute a majority of the ACGL board, they have elected not to do so. Bye-law 20, as amended, provides protection to these investors by allowing three of their designees on the board, or any group of three directors, to call a special meeting of the board of directors

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

(a) The annual meeting of shareholders (the "Annual Meeting") of ACGL was held on June 27, 2002.

(b) Proxies for the Annual Meeting were solicited pursuant to Regulation 14 under the Exchange Act. There was no solicitation in opposition to management's nominees as listed in ACGL's proxy statement, dated June 4, 2002 (the "Proxy Statement").

(c) The shareholders of ACGL (1) elected the following Class I Directors to hold office until the 2005 annual meeting of shareholders or until their successors are elected and qualified: Paul B. Ingrey, Kewsong Lee, David R. Tunnell and Robert F. Works, (2) adopted an amendment to ACGL's bye-law 20 as set forth and described in the Proxy Statement, (3) approved the share-based awards to the Chairman and the Vice-Chairman of the Board of Directors of ACGL in connection with the capital fusion in November 2001,
(4) approved the ACGL 2002 Long Term Incentive and Share Award Plan, (5) elected certain individuals as Designated Company Directors of certain of ACGL's non-U.S. subsidiaries, and (6) ratified the selection of PricewaterhouseCoopers LLP as independent auditors for the fiscal year ending December 31, 2002.

-3-

Wroughton, (ii) the Class II directors, with a term ending in 2003, are Peter

At each succeeding annual general meeting beginning in 2001, successors to the class of directors whose term expires at that annual general meeting shall be elected for a three-year term. If the number of Directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of Directors in each class as nearly equal as possible, and any additional Director of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class, but in no case will a decrease in the number of Directors shorten the term of any incumbent Director. A Director shall hold office until the annual general meeting for the year in which his term expires and until his successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office.

(3) Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preference Shares issued by the Company shall have the right, voting separately by class or series, to elect Directors

-4-

at an annual or special general meeting, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of the Board resolution creating such classes or series of Preference Shares, and such directors so elected shall not be divided into classes pursuant to this Bye-law 11 unless expressly provided by such terms.

12. DEFECTS IN APPOINTMENT OF DIRECTORS

All acts done bona fide by any meeting of the Board or by a committee of the Board or by any person acting as a Director shall, notwithstanding that it be afterwards discovered that there was some defect in the appointment of any Director or person acting as aforesaid, or that they or any of them were disqualified, be as valid as if every such person had been duly appointed and was qualified to be a Director.

13. NOTIFICATION OF NOMINATIONS

Subject to the rights of the holders of any class or series of Preference Shares, nominations for the election of Directors may be made by the Board or by any Member entitled to vote for the election of Directors. Any Member entitled to vote for the election of Directors may nominate persons for election as Directors only if written notice of such Member's intent to make such nomination is delivered to the Secretary of the Company not later than (i) with respect to an election to be held at an annual general meeting, 50 days prior to the date of the meeting at which such nominations are proposed to be voted upon (or if less than 55 days' notice of the meeting is given, not later than the close of business on the seventh day following the day notice of the meeting is first given to Members) and (ii) with respect to an election to be held at a special general meeting for the election of Directors, the close of business on the seventh day following the date on which notice of such meeting is first given to Members. Each such notice shall set forth: (a) the name and address of the Member who intends to make the nomination and of the person or persons to be nominated; (b) a representation that the Member is a holder of record of shares of the Company entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (c) a description of all arrangements or understandings between the Member and each such nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the Member; (d) such other information regarding each nominee proposed by such Member as would have been required to be included in a proxy statement filed pursuant to the proxy rules of the United States Securities and Exchange Commission had each such nominee been nominated, or intended to be nominated, by the Board; and (e) the consent of each such nominee to serve as a director of the Company if so elected. The Chairman of the meeting may refuse to acknowledge the nomination of any person not made in compliance with the foregoing procedure.

14. ALTERNATE DIRECTORS

An individual may be appointed an Alternate Director by or in accordance with a resolution of the members. Unless otherwise determined by the Board (and subject to such limitations as may be set by the Board), no Director shall have the right to appoint another person to act as his Alternate Director.

15. VACANCIES ON THE BOARD; REMOVAL OF DIRECTORS, ETC.

(1) Except in the case of vacancies on the Board that under applicable law must be filled by the Members, any vacancy on the Board that results from an increase in the number of directors shall be filled by a majority of the Directors then in office, provided that a quorum is present, and any other vacancy occurring in the Board shall be filled by a majority of the Directors then in office, even if less than a quorum, or a sole remaining director and the Board shall have the power to appoint an Alternate Director for any Director appointed to fill a vacancy. Any Director elected to fill a vacancy not resulting from an increase in the number of directors shall have the same remaining term as that of his predecessor. If the number of Directors is changed, any increase or decrease shall be apportioned among the three classes so as to make all classes as nearly equal in number as possible. No decrease in the number of Directors shall shorten the term of any incumbent Director.

-5-

(2) A Director may be removed only for cause as determined by the affirmative vote of the holders of at least a majority of the shares then entitled to vote generally in an election of Directors, which vote may only be taken at a special general meeting of the Members called expressly for that purpose. Cause for removal shall be deemed to exist only if the Director whose removal is proposed has been convicted of a felony by a court of competent jurisdiction or has been adjudged by a court of competent jurisdiction to be liable for gross negligence or misconduct in the performance of such Director's duty to the Company and such adjudication is no longer subject to direct appeal.

16. NOTICE OF MEETINGS OF THE BOARD; ADJOURNMENT

(1) Notice of the time and place of each meeting of the Board shall be served upon or telephoned or telegraphed or transmitted by facsimile or e-mail to each Director at his residence or usual place of business, at least two (2) business days before the time fixed for the meeting, or so mailed at least five (5) business days before the time fixed for the meeting.

(2) A majority of the Directors present, whether or not a quorum is present, may adjourn any Directors meeting to another time and place. Notice of the time and place of holding an adjourned meeting need not be given to absent Directors if the time and place be fixed at the meeting adjourned.

-12-

(5) Notwithstanding the foregoing provisions of this Bye-law 45, after having applied such provisions as best as they consider reasonably practicable, the Board may make such final adjustments to the aggregate number of votes conferred, directly or indirectly or by attribution, by the Controlled Shares on any U.S. Person that they consider fair and reasonable in all the circumstances to ensure that such votes represent 9.9% (or the percentage designated by a Member pursuant to paragraph (4) of this Bye-law 45) of the aggregate voting power of the votes conferred by all the shares of the Company entitled to vote generally at any election of Directors. Such adjustments intended to implement the 9.9% limitation set forth in paragraph (2) of this Bye-law 45 shall be subject to the proviso contained in such paragraph (2), but adjustments intended to implement the limitation set forth in a notification pursuant to paragraph (4) of this Bye-law 45 shall not be subject to the proviso contained in paragraph (2).

(6) Each Member shall provide the Company with such information as the Company may reasonably request so that the Company and the Board may make determinations as to the ownership (direct or indirect or by attribution) of Controlled Shares to such Member or to any person to which Shares may be attributed as a result of the ownership of Shares by such Member.

Any such objection made in due time shall be referred to the Chairman of the general meeting whose decisions shall be final and conclusive. Notwithstanding, however, the foregoing or any other provision in these Bye-laws, the Chairman of the general meeting may, in his discretion, whether or not an objection has been raised, and if the Chairman considers that such action is necessary to determine accurately the vote count, defer until after the conclusion of the general meeting a decision as to the proper application of Bye-law 45 to any vote at such meeting.

49. SENIORITY OF JOINT HOLDERS VOTING

In the case of joint holders the vote of the senior who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of the other joint holders, and for this purpose seniority shall be determined by the order in which the names stand in the Register of Members.

(b) determining the Members entitled to receive notice of and to vote at any general meeting of the Company.

TRANSFER OF SHARES

59. INSTRUMENT OF TRANSFER

(1) An instrument of transfer shall be in such common form as the Board may accept. Such instrument of transfer shall be signed by or on behalf of the transferor. The transferor shall be deemed to remain the holder of such share until the same has been transferred to the transferee in the Register of Members.

-17-

(2) The Board may refuse to recognize any instrument of transfer unless it is accompanied by the certificate in respect of the shares to which it relates and by such other evidence as the Board may reasonably require to show the right of the transferor to make the transfer.

60. RESTRICTION ON TRANSFER

(1) The Board shall refuse to register a transfer unless all applicable consents, authorisations and permissions of any governmental body or agency in Bermuda have been obtained.

(2) If the Board refuses to register a transfer of any share the Secretary shall, within three months after the date on which the transfer was lodged with the Company, send to the transferor and transferee notice of the refusal.

61. TRANSFERS BY JOINT HOLDERS

Nothing herein contained shall release the estate of a deceased joint holder from any liability in respect of any share which had been jointly held by such deceased Member with other persons. Subject to the provisions of Section 52 of the Act, for the purpose of this Bye-law, legal personal representative means the executor or administrator of a deceased Member or such other person as the Board may in its absolute discretion decide as being properly authorized to deal with the shares of a deceased Member.

63. REGISTRATION ON DEATH OR BANKRUPTCY

Any person becoming entitled to a share in consequence of the death or bankruptcy of any Member may be registered as a Member upon such evidence as the Board may deem sufficient or may elect to nominate some person to be registered as a transferee of such share, and in such case the person becoming entitled shall execute in favour of such nominee an instrument of transfer satisfactory to the Board. On the presentation thereof to the Board, accompanied by such evidence as the Board may require to prove the title of the transferor, the transferee shall be registered as a Member but the Board shall, in either case, have the same right to decline or suspend registration as it would have had in the case of a transfer of the share by that Member before such Member's death or bankruptcy, as the case may be.

DIVIDENDS AND OTHER DISTRIBUTIONS

64. DECLARATION OF DIVIDENDS BY THE BOARD

The Board may declare and make such dividends or other distributions (in each case in cash or in specie, as valued by the Board, or a combination thereof) to the Members as may be lawfully made out of the assets of the Company.

-18-

65. UNCLAIMED DIVIDENDS

Any dividend or other monies payable in respect of a share which has remained unclaimed for 5 years from the date when it became due for payment shall, if the Board so resolves, be forfeited and cease to remain owing by the Company. The payment of any unclaimed dividend or other moneys payable in respect of a share may (but need not) be paid by the Company into an account separate from the Company's own account. Such payment shall not constitute the Company a trustee in respect thereof.

66. UNDELIVERED PAYMENTS

The Company shall be entitled to cease sending dividend payments and cheques by post or otherwise to a Member if those instruments have been returned undelivered to, or left uncashed by, that Member on at least two consecutive occasions, or, following one such occasion, reasonable enquiries have failed to establish the Member's new address. The entitlement conferred on the Company by this Bye-law in respect of any Member shall cease if the Member claims a dividend or cashes a dividend warrant or cheque.

67. INTEREST ON DIVIDENDS

No dividend or distribution shall bear interest against the Company.

CAPITALIZATION

68. ISSUE OF BONUS SHARES

The Board may resolve to capitalize any part of the amount for the time being standing to the credit of any of the Company's share premium or other reserve accounts or to the credit of the profit and loss account or otherwise available for distribution by applying such sum in paying up unissued shares to be allotted as fully paid bonus shares to the Members.

-20-

out as between the Members or different classes of Members. The liquidator may, with the like sanction, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the Members as the liquidator shall think fit, but so that no Member shall be compelled to accept any shares or other securities or assets whereon there is any liability.

(v) to determine whether, to what extent, and under what circumstances an Award may be settled, or the exercise price of an Award may be paid, in cash, Shares, other Awards, or other property, or an Award may be cancelled, forfeited, exchanged, or surrendered;

(vi) to determine whether, to what extent, and under what circumstances cash, Shares, other Awards, or other property payable with respect to an Award will be deferred either automatically, at the election of the Committee, or at the election of the Eligible Employee;

(vii) to prescribe the form of each Award Agreement, which need not be identical for each Eligible Employee;

(viii) to adopt, amend, suspend, waive, and rescind such rules and regulations and appoint such agents as the Committee may deem necessary or advisable to administer the Plan;

C-3

(ix) to correct any defect or supply any omission or reconcile any inconsistency in the Plan and to construe and interpret the Plan and any Award, rules and regulations, Award Agreement, or other instrument hereunder;

(x) to accelerate the exercisability or vesting of all or any portion of any Award or to extend the period during which an Award is exercisable; and

(xi) to make all other decisions and determinations as may be required under the terms of the Plan or as the Committee may deem necessary or advisable for the administration of the Plan.

(b) MANNER OF EXERCISE OF COMMITTEE AUTHORITY. The Committee shall have sole discretion in exercising its authority under the Plan. Any action of the Committee with respect to the Plan shall be final, conclusive, and binding on all persons, including the Company, Subsidiaries, Affiliates, Eligible Employees, any person claiming any rights under the Plan from or through any Eligible Employee, and shareholders. The express grant of any specific power to the Committee, and the taking of any action by the Committee, shall not be construed as limiting any power or authority of the Committee. The Committee may delegate to officers or managers of the Company or any Subsidiary or Affiliate the authority, subject to such terms as the Committee shall determine, to perform administrative functions and, with respect to Awards granted to persons not subject to Section 16 of the Exchange Act, to perform such other functions as the Committee may determine, to the extent permitted under Rule 16b-3 (if applicable) and applicable law. Notwithstanding any provision of this Plan to the contrary, the Committee may grant Awards which are subject to the approval of the Board; provided that an Award shall be subject to Board approval only if the Committee expressly so states.

(c) LIMITATION OF LIABILITY. Each member of the Committee shall be entitled to, in good faith, rely or act upon any report or other information furnished to him or her by any officer or other employee of the Company or any Subsidiary or Affiliate, the Company's independent certified public accountants, or other professional retained by the Company to assist in the administration of the Plan. No member of the Committee, nor any officer or employee of the Company acting on behalf of the Committee, shall be personally liable for any action, determination, or interpretation taken or made in good faith with respect to the Plan, and all members of the Committee and any officer or employee of the Company acting on their behalf shall, to the extent permitted by law, be fully indemnified and protected by the Company with respect to any such action, determination, or interpretation.

(d) LIMITATION ON COMMITTEE'S DISCRETION. Anything in this Plan to the contrary notwithstanding, in the case of any Award which is intended to qualify as "performance-based compensation" within the meaning of Section 162(m)(4)(C) of the Code, if the Award Agreement so provides, the Committee shall have no discretion to increase the amount of compensation payable under the Award to the extent such an increase would cause the Award to lose its qualification as such performance-based compensation.

4. SHARES SUBJECT TO THE PLAN.

(a) Subject to adjustment as provided in Section 4(c) hereof, the total number of Shares reserved for issuance under the Plan shall be 3,165,830. No Award may be granted if the number of Shares to which such Award relates, when added to the number of Shares previously issued under the Plan, exceeds the number of Shares reserved under the preceding sentence. If any Awards are forfeited, cancelled, terminated, exchanged or surrendered or such Award is settled in cash or otherwise terminates without a distribution of Shares to the Participant, any Shares counted against the number of Shares reserved and available under the Plan with respect to such Award shall, to the extent of any such forfeiture, settlement, termination, cancellation, exchange or surrender, again be available for Awards under the Plan. Upon the exercise of any Award granted in tandem with any other Awards, such related Awards shall be cancelled to the extent of the number of Shares as to which the Award is exercised. Subject to adjustment as provided in Section 4(c) hereof, the maximum number

C-4

of Shares (i) with respect to which Options and SARs may be granted during a calendar year to any Eligible Employee under this Plan shall be 1,000,000 Shares and (ii) with respect to Performance Shares, Performance Units, Restricted Shares and Restricted Share Units intended to qualify as performance-based compensation within the meaning of Section 162(m)(4)(C) of the Code shall be the equivalent of 500,000 Shares during a calendar year to any Eligible Employee under this Plan.

(b) Any Shares distributed pursuant to an Award may consist, in whole or in part, of authorized and unissued Shares or treasury Shares including Shares acquired by purchase in the open market or in private transactions.

(c) In the event that the Committee shall determine that any dividend in Shares, recapitalization, Share split, reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase, or share exchange, or other similar corporate transaction or event, affects the Shares such that an adjustment is appropriate in order to prevent dilution or enlargement of the rights of Eligible Employees under the Plan, then the Committee shall make such equitable changes or adjustments as it deems appropriate and, in such manner as it may deem equitable, adjust any or all of
(i) the number and kind of shares which may thereafter be issued under the Plan,
(ii) the number and kind of shares, other securities or other consideration issued or issuable in respect of outstanding Awards, and (iii) the exercise price, grant price, or purchase price relating to any Award; PROVIDED, HOWEVER, in each case that, with respect to ISOs, such adjustment shall be made in accordance with Section 424(a) of the Code, unless the Committee determines otherwise. In addition, the Committee is authorized to make adjustments in the terms and conditions of, and the criteria and performance objectives included in, Awards in recognition of unusual or non-recurring events (including, without limitation, events described in the preceding sentence) affecting the Company or any Subsidiary or Affiliate or the financial statements of the Company or any Subsidiary or Affiliate, or in response to changes in applicable laws, regulations, or accounting principles; PROVIDED, HOWEVER, that, if an Award Agreement specifically so provides, the Committee shall not have discretion to increase the amount of compensation payable under the Award to the extent such an increase would cause the Award to lose its qualification as performance-based compensation for purposes of Section 162(m)(4)(C) of the Code and the regulations thereunder.

5. SPECIFIC TERMS OF AWARDS.

(a) GENERAL. Awards may be granted on the terms and conditions set forth in this Section 5. In addition, the Committee may impose on any Award or the exercise thereof, at the date of grant or thereafter (subject to Section
9(d)), such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine, including terms regarding forfeiture of Awards or continued exercisability of Awards in the event of termination of employment by the Eligible Employee.

(b) OPTIONS. The Committee is authorized to grant Options, which may be NQSOs or ISOs, to Eligible Employees on the following terms and conditions:

(i) EXERCISE PRICE. The exercise price per Share purchasable under an Option shall be determined by the Committee, and the Committee may, without limitation, set an exercise price that is based upon achievement of performance criteria if deemed appropriate by the Committee.

(ii) OPTION TERM. The term of each Option shall be determined by the Committee, but such term shall not exceed ten years.

(iii) TIME AND METHOD OF EXERCISE. The Committee shall determine at the date of grant or thereafter the time or times at which an Option may be exercised in whole or in part (including, without limitation, upon achievement of performance criteria if deemed appropriate by the Committee), the methods by which such exercise price may be paid or deemed to be paid (including, without

C-5

limitation, broker-assisted exercise arrangements), the form of such payment (including, without limitation, cash, Shares, notes or other property), and the methods by which Shares will be delivered or deemed to be delivered to Eligible Employees; PROVIDED, HOWEVER, that in no event may any portion of the exercise price be paid with Shares acquired either under an Award granted pursuant to this Plan, upon exercise of a stock option granted under another Company plan or as a stock bonus or other stock award granted under another Company plan unless, in any such case, the Shares were acquired and vested more than six months in advance of the date of exercise.

(iv) ISOs. The terms of any ISO granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code, including but not limited to the requirement that no ISO shall be granted more than ten years after the earlier of the date of adoption or shareholder approval of the Plan. ISOs may only be granted to employees of the Company or a Subsidiary.

(c) SARs. The Committee is authorized to grant SARs (Share Appreciation Rights) to Eligible Employees on the following terms and conditions:

(i) RIGHT TO PAYMENT. A SAR shall confer on the Eligible Employee to whom it is granted a right to receive with respect to each Share subject thereto, upon exercise thereof, the excess of (1) the Fair Market Value of one Share on the date of exercise (or, if the Committee shall so determine in the case of any such right, the Fair Market Value of one Share at any time during a specified period before or after the date of exercise) over (2) the exercise price of the SAR as determined by the Committee as of the date of grant of the SAR (which, in the case of a SAR granted in tandem with an Option, shall be equal to the exercise price of the underlying Option).

(ii) OTHER TERMS. The Committee shall determine, at the time of grant or thereafter, the time or times at which a SAR may be exercised in whole or in part (which shall not be more than ten years after the date of grant of the SAR), the method of exercise, method of settlement, form of consideration payable in settlement, method by which Shares will be delivered or deemed to be delivered to Eligible Employees, whether or not a SAR shall be in tandem with any other Award, and any other terms and conditions of any SAR. Unless the Committee determines otherwise, a SAR (1) granted in tandem with a NQSO may be granted at the time of grant of the related NQSO or at any time thereafter or (2) granted in tandem with an ISO may only be granted at the time of grant of the related ISO.

(d) RESTRICTED SHARES. The Committee is authorized to grant Restricted Shares to Eligible Employees on the following terms and conditions:

(i) ISSUANCE AND RESTRICTIONS. Restricted Shares shall be subject to such restrictions on transferability and other restrictions, if any, as the Committee may impose at the date of grant or thereafter, which restrictions, if any, may lapse separately or in combination at such times, under such circumstances (including, without limitation, upon achievement of performance criteria if deemed appropriate by the Committee), in such installments or otherwise, as the Committee may determine. Except to the extent restricted under the Award Agreement relating to the Restricted Shares, an Eligible Employee granted Restricted Shares shall have all of the rights of a shareholder including, without limitation, the right to vote Restricted Shares and the right to receive dividends thereon. If the lapse of restrictions is conditioned on the achievement of performance criteria, the Committee shall select the criterion or criteria from the list of criteria set forth in Section 5(f)(i). The Committee must certify in writing prior to the lapse of restrictions conditioned on the achievement of performance criteria that such performance criteria were in fact satisfied.

C-6

(ii) FORFEITURE. Except as otherwise determined by the Committee, at the date of grant or thereafter, upon termination of employment during any applicable restriction period, Restricted Shares and any accrued but unpaid dividends or Dividend Equivalents that are at that time subject to restrictions shall be forfeited; PROVIDED, HOWEVER, that the Committee may provide, by rule or regulation or in any Award Agreement, or may determine in any individual case, that restrictions or forfeiture conditions relating to Restricted Shares will be waived in whole or in part in the event of terminations resulting from specified causes, and the Committee may in other cases waive in whole or in part the forfeiture of Restricted Shares.

(iii) CERTIFICATES FOR SHARES. Restricted Shares granted under the Plan may be evidenced in such manner as the Committee shall determine. If certificates representing Restricted Shares are registered in the name of the Eligible Employee, such certificates shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Shares, and the Company shall retain physical possession of the certificate.

(iv) DIVIDENDS. Dividends paid on Restricted Shares shall be either paid at the dividend payment date, or deferred for payment to such date as determined by the Committee, in cash or in unrestricted Shares having a Fair Market Value equal to the amount of such dividends. Shares distributed in connection with a Share split or dividend in Shares, and other property distributed as a dividend, shall be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Shares with respect to which such Shares or other property has been distributed.

(e) RESTRICTED SHARE UNITS. The Committee is authorized to grant Restricted Share Units to Eligible Employees, subject to the following terms and conditions:

(i) AWARD AND RESTRICTIONS. Delivery of Shares or cash, as the case may be, will occur upon expiration of the deferral period specified for Restricted Share Units by the Committee (or, if permitted by the Committee, as elected by the Eligible Employee). In addition, Restricted Share Units shall be subject to such restrictions as the Committee may impose, if any (including, without limitation, the achievement of performance criteria if deemed appropriate by the Committee), at the date of grant or thereafter, which restrictions may lapse at the expiration of the deferral period or at earlier or later specified times, separately or in combination, in installments or otherwise, as the Committee may determine. If the lapse of restrictions is conditioned on the achievement of performance criteria, the Committee shall select the criterion or criteria from the list of criteria set forth in Section 5(f)(i). The Committee must certify in writing prior to the lapse of restrictions conditioned on the achievement of performance criteria that such criteria were in fact satisfied.

(ii) FORFEITURE. Except as otherwise determined by the Committee at date of grant or thereafter, upon termination of employment (as determined under criteria established by the Committee) during the applicable deferral period or portion thereof to which forfeiture conditions apply (as provided in the Award Agreement evidencing the Restricted Share Units), or upon failure to satisfy any other conditions precedent to the delivery of Shares or cash to which such Restricted Share Units relate, all Restricted Share Units that are at that time subject to deferral or restriction shall be forfeited; PROVIDED, HOWEVER, that the Committee may provide, by rule or regulation or in any Award Agreement, or may determine in any individual case, that restrictions or forfeiture conditions relating to Restricted Share Units will be waived in whole or in part in the event of termination resulting from specified causes, and the Committee may in other cases waive in whole or in part the forfeiture of Restricted Share Units.

(f) PERFORMANCE SHARES AND PERFORMANCE UNITS. The Committee is authorized to grant Performance Shares or Performance Units or both to Eligible Employees on the following terms and conditions:

C-7

(i) PERFORMANCE PERIOD. The Committee shall determine a performance period (the "Performance Period") of one or more years and shall determine the performance objectives for grants of Performance Shares and Performance Units. Performance objectives may vary from Eligible Employee to Eligible Employee and shall be based upon such one or more of the following performance criteria as the Committee may deem appropriate: growth in book, economic book and/or intrinsic book value; appreciation in value of the Shares; total shareholder return; earnings per share; comprehensive income; operating income; net income; pretax earnings; pretax earnings before interest, depreciation and amortization; pro forma net income; return on equity; return on designated assets; return on capital; economic value added; earnings; revenues; expenses; operating profit margin; operating cash flow; free cash flow; cash flow return on investment; operating margin; net profit margin; or any of the above criteria as compared to the performance of a published or special index deemed applicable by the Committee, including, but not limited to, the Standard & Poor's 500 Stock Index. The performance objectives may be determined by reference to the performance of the Company, or of a Subsidiary or Affiliate, or of a division or unit of any of the foregoing. Performance Periods may overlap and Eligible Employees may participate simultaneously with respect to Performance Shares and Performance Units for which different Performance Periods are prescribed.

(ii) AWARD VALUE. At the beginning of a Performance Period, the Committee shall determine for each Eligible Employee or group of Eligible Employees with respect to that Performance Period the range of number of Shares, if any, in the case of Performance Shares, and the range of dollar values, if any, in the case of Performance Units, which may be fixed or may vary in accordance with such performance or other criteria specified by the Committee, which shall be paid to an Eligible Employee as an Award if the relevant measure of Company performance for the Performance Period is met. The Committee must certify in writing that the applicable performance criteria were satisfied prior to payment under any Performance Shares or Performance Units.

(iii) SIGNIFICANT EVENTS. If during the course of a Performance Period there shall occur significant events as determined by the Committee which the Committee expects to have a substantial effect on a performance objective during such period, the Committee may revise such objective; PROVIDED, HOWEVER, that, if an Award Agreement so provides, the Committee shall not have any discretion to increase the amount of compensation payable under the Award to the extent such an increase would cause the Award to lose its qualification as performance-based compensation for purposes of
Section 162(m)(4)(C) of the Code and the regulations thereunder.

(iv) FORFEITURE. Except as otherwise determined by the Committee, at the date of grant or thereafter, upon termination of employment during the applicable Performance Period, Performance Shares and Performance Units for which the Performance Period was prescribed shall be forfeited; PROVIDED, HOWEVER, that the Committee may provide, by rule or regulation or in any Award Agreement, or may determine in an individual case, that restrictions or forfeiture conditions relating to Performance Shares and Performance Units will be waived in whole or in part in the event of terminations resulting from specified causes, and the Committee may in other cases waive in whole or in part the forfeiture of Performance Shares and Performance Units.

(v) PAYMENT. Each Performance Share or Performance Unit may be paid in whole Shares, or cash, or a combination of Shares and cash either as a lump sum payment or in installments, all as the Committee shall determine, at the time of grant of the Performance Share or Performance Unit or otherwise, commencing as soon as practicable after the end of the relevant Performance Period. The Committee must certify in writing prior to the payment of any Performance Share or Performance Unit that the performance objectives and any other material terms were in fact satisfied.

(g) DIVIDEND EQUIVALENTS. The Committee is authorized to grant Dividend Equivalents to Eligible Employees. The Committee may provide, at the date of grant or thereafter, that Dividend Equivalents

C-8

shall be paid or distributed when accrued or shall be deemed to have been reinvested in additional Shares, or other investment vehicles as the Committee may specify, provided that Dividend Equivalents (other than freestanding Dividend Equivalents) shall be subject to all conditions and restrictions of the underlying Awards to which they relate.

(h) OTHER SHARE-BASED AWARDS. The Committee is authorized, subject to limitations under applicable law, to grant to Eligible Employees such other Awards that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, Shares, as deemed by the Committee to be consistent with the purposes of the Plan, including, without limitation, unrestricted shares awarded purely as a "bonus" and not subject to any restrictions or conditions, other rights convertible or exchangeable into Shares, purchase rights for Shares, Awards with value and payment contingent upon performance of the Company or any other factors designated by the Committee, and Awards valued by reference to the performance of specified Subsidiaries or Affiliates. The Committee shall determine the terms and conditions of such Awards at date of grant or thereafter. Shares delivered pursuant to an Award in the nature of a purchase right granted under this
Section 5(h) shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including, without limitation, cash, Shares, notes or other property, as the Committee shall determine. Cash awards, as an element of or supplement to any other Award under the Plan, shall also be authorized pursuant to this Section 5(h).

6. CERTAIN PROVISIONS APPLICABLE TO AWARDS.

(a) STAND-ALONE, ADDITIONAL, TANDEM AND SUBSTITUTE AWARDS. Awards granted under the Plan may, in the discretion of the Committee, be granted to Eligible Employees either alone or in addition to, in tandem with, or in exchange or substitution for, any other Award granted under the Plan or any award granted under any other plan or agreement of the Company, any Subsidiary or Affiliate, or any business entity to be acquired by the Company or a Subsidiary or Affiliate, or any other right of an Eligible Employee to receive payment from the Company or any Subsidiary or Affiliate. Awards may be granted in addition to or in tandem with such other Awards or awards, and may be granted either as of the same time as or a different time from the grant of such other Awards or awards. The per Share exercise price of any Option, grant price of any SAR, or purchase price of any other Award conferring a right to purchase Shares which is granted, in connection with the substitution of awards granted under any other plan or agreement of the Company or any Subsidiary or Affiliate or any business entity to be acquired by the Company or any Subsidiary or Affiliate, shall be determined by the Committee, in its discretion. Notwithstanding the foregoing, the exercise price of any Option, grant price of any SAR or purchase price of any other Award conferring a right to purchase Shares which is granted in exchange or substitution for an option, SAR or other award granted by the Company (other than in connection with a transaction described in Section 4(c) hereof) shall not be less than the exercise price, grant price or purchase price of the exchanged or substituted option, SAR or other award, and outstanding Awards shall not be amended (other than in connection with a transaction described in Section 4(c) hereof) to reduce the exercise price, grant price or purchase price of any such Award.

(b) TERMS OF AWARDS. The term of each Award granted to an Eligible Employee shall be for such period as may be determined by the Committee; PROVIDED, HOWEVER, that in no event shall the term of any ISO or a SAR granted in tandem therewith exceed a period of ten years from the date of its grant (or such shorter period as may be applicable under Section 422 of the Code).

(c) FORM OF PAYMENT UNDER AWARDS. Subject to the terms of the Plan and any applicable Award Agreement, payments to be made by the Company or a Subsidiary or Affiliate upon the grant, maturation, or exercise of an Award may be made in such forms as the Committee shall determine at the date of grant or thereafter, including, without limitation, cash, Shares, or other property, and may be made in a single payment or transfer, in installments, or on a deferred basis. The Committee may make rules relating to installment or deferred payments with respect to Awards, including the rate of interest to be credited with respect to such payments.

C-9

(d) NONTRANSFERABILITY. Except as set forth below and except for vested Shares, Awards shall not be transferable by an Eligible Employee except by will or the laws of descent and distribution (except pursuant to a Beneficiary designation) and shall be exercisable during the lifetime of an Eligible Employee only by such Eligible Employee or his guardian or legal representative. Notwithstanding the foregoing, if the Committee expressly so provides in the applicable Award agreement (at the time of grant or at any time thereafter), an Award (other than an ISO) granted hereunder may be transferred by a Participant to members of his or her "immediate family" or to a trust established for the exclusive benefit of solely one or more members of the Participant's "immediate family." Any Award held by the transferee will continue to be subject to the same terms and conditions that were applicable to the Award immediately prior to the transfer, except that the Award will be transferable by the transferee only by will or the laws of descent and distribution. For purposes hereof, "immediate family." means the Participant's children, stepchildren, grandchildren, parents, stepparents, grandparents, spouse, siblings (including half brothers and sisters), in-laws, and relationships arising because of legal adoption. An Eligible Employee's rights under the Plan may not be pledged, mortgaged, hypothecated, or otherwise encumbered, and shall not be subject to claims of the Eligible Employee's creditors.

(e) NONCOMPETITION. The Committee may, by way of the Award Agreements or otherwise, establish such other terms, conditions, restrictions and/or limitations, if any, of any Award, provided they are not inconsistent with the Plan, including, without limitation, the requirement that the Participant not engage in competition with the Company.

7. DIRECTOR'S OPTIONS.

(a) ANNUAL GRANT. On January 1 of each year, each Director in office on such date shall automatically be granted a NQSO to purchase 1500 Shares with an exercise price per Share equal to 100% of the Market Value of one Share on the date of grant; provided, however, that such price shall be at least equal to the par value of a Share. Each Option granted to a Director under this paragraph (a) shall become fully exercisable on the first anniversary of the date the Option is granted, and shall expire (unless terminated earlier under paragraph (d) below) on the tenth anniversary of the date of grant.

(b) INITIAL GRANTS. Each Director will automatically be granted a NQSO on the date he or she is first elected to the Board to purchase 300 Shares with an exercise price per Share equal to 100% of the Market Value of one Share on the date of grant; PROVIDED, HOWEVER, that such price shall be at least equal to the par value of a Share. Each Option granted to a Director under this paragraph (b) shall become exercisable in three equal installments, commencing on the date of grant and annually thereafter. Each Option granted under this paragraph (b) shall expire (unless terminated earlier under paragraph (d) below) on the tenth anniversary of the date of grant.

(c) MARKET VALUE. For purposes of this Section 7, Market Value shall mean the mean between the high and low selling prices per Share on the immediately preceding date (or, if the Shares were not traded on that day, the next preceding day that the Shares were traded) on the principal exchange on which the Shares are traded, as such prices are officially quoted on such exchange.

(d) TERMINATION OF SERVICE. If a person ceases to be a Director,
(i) due to retirement after attainment of age 65, or (ii) due to death or disability, all of his or her outstanding Options, to the extent not already exercisable in full, shall become immediately and fully exercisable at the time of termination of service, and all of such Director's Options may be exercised at any time prior to the expiration dates of such Options. If the Director's service terminates for any other reason, all Options which are not then exercisable shall be cancelled on the date service terminates, and Options which are then exercisable may be exercised at any time within six months after the date of such termination, but not later than the expiration date of the Options.

C-10

(e) TIME AND METHOD OF EXERCISE. The exercise price of a Director's Option shall be paid to the Company (including, without limitation, through broker-assisted exercise arrangements) at the time of exercise either in cash, or in Shares already owned by the optionee and having a total Market Value equal to the exercise price, or in a combination of cash and such Shares.

(f) NONTRANSFERABILITY. No Director's Option granted under the Plan shall be transferable other than by will or by the laws of descent and distribution. During the lifetime of the optionee, a Director's Option shall be exercisable only by him or her or by his or her guardian or legal representative. Notwithstanding the foregoing, if the Committee expressly so provides in the applicable Award agreement (at the time of grant or at any time thereafter), a Director's Option granted hereunder may be transferred by an optionee to members of his or her "immediate family" or to a trust established for the exclusive benefit of solely one or more members of his or her "immediate family." Any Director's Option held by the transferee will continue to be subject to the same terms and conditions that were applicable to the Director's Option immediately prior to the transfer, except that the Director's Option will be transferable by the transferee only by will or the laws of descent and distribution. For purposes hereof, "immediate family" means the Director's children, stepchildren, grandchildren, parents, stepparents, grandparents, spouse, siblings (including half brothers and sisters), in-laws, and relationships arising because of legal adoption.

(g) ADJUSTMENTS. In the event that subsequent to the Effective Date any dividend in Shares, recapitalization, Share split, reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase, or share exchange, or other such change, affects the Shares such that they are increased or decreased or changed into or exchanged for a different number or kind of shares, other securities of the Company or of another corporation or other consideration, then in order to maintain the proportionate interest of the Director and preserve the value of the Director's Option, (i) there shall automatically be substituted for each Share subject to an unexercised Director's Option and each Share to be issued under Section 7(a) or 7(b) subsequent to such event the number and kind of shares, other securities or other consideration into which each outstanding Share shall be changed or for which each such Share shall be exchanged, and (ii) the exercise price shall be increased or decreased proportionately so that the aggregate purchase price for the Shares subject to any unexercised Director's Option shall remain the same as immediately prior to such event.

(h) EXCLUSIVE SOURCE OF FORMULA GRANTS. Unless otherwise determined by the Board, automatic grants of stock options shall be made to Directors only pursuant to this Plan, and the automatic stock option grant provisions of any plan of the Company adopted prior to the Effective Date shall be terminated upon approval of this Plan by the shareholders of the Company.

8. DIRECTOR'S SHARES. Each Director may make an election in writing on or prior to each August 1 to receive the Director's annual retainer fees payable thereafter in the form of Shares instead of cash. Any Shares elected shall be payable at the time cash retainer fees are otherwise payable, and the number of Shares distributed shall be equal to 120 percent of the amount of the annual retainer fee otherwise payable on such payment date divided by the Fair Market Value of a Share on such date. Notwithstanding the foregoing, a Director who is first elected or appointed to the Board may make an election under this
Section 8 within 30 days of such election or appointment in respect of annual retainer fees payable after the date of the election. Any election made under this Section 8 shall remain in effect unless and until a new election is made in accordance with the provisions of this Section 8.

9. GENERAL PROVISIONS.

(a) COMPLIANCE WITH LEGAL AND TRADING REQUIREMENTS. The Plan, the granting and exercising of Awards thereunder, and the other obligations of the Company under the Plan and any Award Agreement, shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may be required. The Company, in its discretion, may postpone the issuance or delivery of Shares under any Award until completion of such stock exchange or market

C-11

system listing or registration or qualification of such Shares or other required action under any state or federal law, rule or regulation as the Company may consider appropriate, and may require any Participant to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Shares in compliance with applicable laws, rules and regulations. No provisions of the Plan shall be interpreted or construed to obligate the Company to register any Shares under federal, state or foreign law.

(b) NO RIGHT TO CONTINUED EMPLOYMENT OR SERVICE. Neither the Plan nor any action taken thereunder shall be construed as giving any employee or director the right to be retained in the employ or service of the Company or any of its Subsidiaries or Affiliates, nor shall it interfere in any way with the right of the Company or any of its Subsidiaries or Affiliates to terminate any employee's or director's employment or service at any time.

(c) TAXES. The Company or any Subsidiary or Affiliate is authorized to withhold from any Award granted, any payment relating to an Award under the Plan, including from a distribution of Shares, or any payroll or other payment to an Eligible Employee, amounts of withholding and other taxes due in connection with any transaction involving an Award, and to take such other action as the Committee may deem advisable to enable the Company and Eligible Employees to satisfy obligations for the payment of withholding taxes and other tax obligations relating to any Award. This authority shall include authority to withhold or receive Shares or other property and to make cash payments in respect thereof in satisfaction of an Eligible Employee's tax obligations; PROVIDED, HOWEVER, that the amount of tax withholding to be satisfied by withholding Shares shall be limited to the minimum amount of taxes, including employment taxes, required to be withheld under applicable Federal, state and local law.

(d) CHANGES TO THE PLAN AND AWARDS. The Board may amend, alter, suspend, discontinue, or terminate the Plan or the Committee's authority to grant Awards under the Plan without the consent of shareholders of the Company or Participants, except that any such amendment, alteration, suspension, discontinuation, or termination shall be subject to the approval of the Company's shareholders to the extent such shareholder approval is required under
Section 422 of the Code; PROVIDED, HOWEVER, that, without the consent of an affected Participant, no amendment, alteration, suspension, discontinuation, or termination of the Plan may impair the rights or, in any other manner, adversely affect the rights of such Participant under any Award theretofore granted to him or her. The Committee may waive any conditions or rights under, amend any terms of, or amend, alter, suspend, discontinue or terminate, any Award theretofore granted, prospectively or retrospectively; PROVIDED, HOWEVER, that, without the consent of a Participant, no amendment, alteration, suspension, discontinuation or termination of any Award may materially and adversely affect the rights of such Participant under any Award theretofore granted to him or her.

(e) NO RIGHTS TO AWARDS; NO SHAREHOLDER RIGHTS. No Eligible Employee or employee shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Eligible Employees and employees. No Award shall confer on any Eligible Employee any of the rights of a shareholder of the Company unless and until Shares are duly issued or transferred to the Eligible Employee in accordance with the terms of the Award.

(f) UNFUNDED STATUS OF AWARDS. The Plan is intended to constitute an "unfunded" plan for incentive compensation. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award shall give any such Participant any rights that are greater than those of a general creditor of the Company; PROVIDED, HOWEVER, that the Committee may authorize the creation of trusts or make other arrangements to meet the Company's obligations under the Plan to deliver cash, Shares, other Awards, or other property pursuant to any Award, which trusts or other arrangements shall be consistent with the "unfunded" status of the Plan unless the Committee otherwise determines with the consent of each affected Participant.

C-12

(g) NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the Board nor its submission to the shareholders of the Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of options and other awards otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

(h) NOT COMPENSATION FOR BENEFIT PLANS. No Award payable under this Plan shall be deemed salary or compensation for the purpose of computing benefits under any benefit plan or other arrangement of the Company for the benefit of its employees or directors unless the Company shall determine otherwise.

(i) NO FRACTIONAL SHARES. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award. In the case of Awards to Eligible Employees, the Committee shall determine whether cash, other Awards, or other property shall be issued or paid in lieu of such fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated. In the case of Director's Options, cash shall be paid in lieu of such fractional shares.

(j) GOVERNING LAW. The validity, construction, and effect of the Plan, any rules and regulations relating to the Plan, and any Award Agreement shall be determined in accordance with the laws of New York without giving effect to principles of conflict of laws.

(k) EFFECTIVE DATE; PLAN TERMINATION. The Plan, as amended and restated, shall become effective as of January 1, 2002 (the "Effective Date"), subject to approval by the shareholders of the Company. The Plan shall terminate as to future awards on the date which is 10 years after the Effective Date.

(l) TITLES AND HEADINGS. The titles and headings of the sections in the Plan are for convenience of reference only. In the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

(c) Each Obligor will, without expense to the Lender, procure or cause to be procured promptly all necessary licenses which are required with respect to the transaction(s) which is/are the subject of any Letter of Credit issued for such Obligor or to which any such Letter of Credit relates, will comply with or cause to be complied with all applicable governmental regulations in regard thereto, and will furnish or cause to be furnished to the Lender such documents and certificates in respect thereof as the Lender may reasonably require.

same or any part thereof and apply the same to any liability or obligation of such Obligor even though unmatured and regardless of the adequacy of any other collateral securing such Obligor's obligations hereunder. ANY AND ALL RIGHTS TO REQUIRE THE LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES AN OBLIGOR'S OBLIGATIONS HEREUNDER, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF SUCH OBLIGOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

Each Obligor hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue to any suit, action or proceeding arising out or relating to this Agreement brought in any federal or state courts sitting in the State of Connecticut and hereby further irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

EACH OBLIGOR CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR THE LENDER TO ENTER INTO THIS AGREEMENT AND THE OTHER FUNDAMENTAL DOCUMENTS.

Section 8.10 INTEREST.

All agreements between the Lender and the Obligors are hereby expressly limited so that in no contingency or event whatsoever shall the amount paid or agreed to be paid to the Lender for the use or the forebearance of the indebtedness evidenced hereby exceed the maximum permissible under applicable law. As used herein, the term "applicable law" shall mean the law in effect as of the date hereof; provided, however, that in the event there is a change in the law which results in a higher permissible rate of interest, then this Agreement shall be governed by such new law as of its effective date. In this regard, it is expressly agreed that it is the intent of the Lender and the Obligors in the execution, delivery and acceptance of this Agreement to contract in strict compliance with the laws of the State of Connecticut from time to time in effect. If, under or from any circumstances whatsoever, fulfillment of any provision hereof or of any of the agreements executed herewith at the time of performance of such provision shall be due, shall involve transcending the limit of such validity prescribed by applicable law, then the obligation to be fulfilled shall automatically be reduced to the limits of such validity, and if under or from circumstances whatsoever the Lender should ever receive as interest an amount which would exceed the highest lawful rate, such amount which would be excessive interest shall be applied to the reduction of the principal balance evidenced hereby and not to the payment of interest. This provision shall control every other provision of all agreements between the Obligors and the Lender.

SECURITY AGREEMENT

SECURITY AGREEMENT (the "Agreement") dated as of April 17, 2002 between ARCH REINSURANCE COMPANY, a corporation organized and existing under the laws of Nebraska, ("Arch Company" or "Debtor") and FLEET NATIONAL BANK, as the Lender under the below referenced Letter of Credit Agreement (the "Lender").

W I T N E S S E T H:

WHEREAS, the Lender as the issuer of Letters of Credit has entered into a Letter of Credit and Reimbursement Agreement dated as of April 17, 2002 (as such agreement may hereafter be amended or otherwise modified from time to time, being the "Letter of Credit Agreement") with Arch Reinsurance Ltd., Arch Company, Alternative Re Limited and First American Insurance Company;

WHEREAS, it is a condition precedent to the issuance of Letters of Credit by the Lender under the Letter of Credit Agreement that the Debtor shall have executed and delivered to the Lender this Agreement and pledged and granted a security interest in the Collateral, as such term is defined below, held by or on behalf of the Debtor from time to time and other rights and interests contemplated by this Agreement; and

WHEREAS, pursuant to the terms of the Custodian Agreement, the Custodian has established a Custodial Account, account #0010409270 (the "Custodial Account"), in the name of the Debtor and the Company hereby grants to the Lender a security interest in the Collateral, including the Custodial Account.

NOW, THEREFORE, in consideration of the premises and in order to induce the Lender to issue Letters of Credit for the account of the Debtor under the Letter of Credit Agreement, Arch Company hereby agrees with the Lender as follows (all capitalized terms used herein shall have the meanings set forth in SCHEDULE 1 hereto or, if not defined therein, in the Letter of Credit Agreement):

1. GRANT OF SECURITY. The Debtor hereby pledges to the Lender and grants to the Lender for its benefit a security interest in and lien upon, all of the Debtor's right, title and interest in and to the following, in each case whether now or hereafter existing or in which the Debtor now has or hereafter acquires an interest and wherever the same may be located (collectively, the "Collateral"):

(i) The Custodial Account, including all cash held therein or credited thereto from time to time, and all securities, instruments and investments, including Investments, and other "investment property" and "financial assets," as each such term is defined in the UCC, of any kind held therein or credited thereto from time to time) (the "Pledged Investments"); and


(ii) All proceeds of, accessions to, substitutions for, and earnings on, any and all of the foregoing Collateral (including, without limitation, proceeds that constitute property of the types described in clauses (i) and (ii) above) and, to the extent not otherwise included, all payments under insurance (whether or not the Lender is the loss payee thereof), or any indemnity, warranty or guaranty, payable by reason of loss or damage to or otherwise with respect to any of the foregoing Collateral. For purposes hereof, the term "proceeds" includes whatever is receivable or received when Collateral or proceeds are sold, collected, exchanged or otherwise disposed of, whether such disposition is voluntary or involuntary, and includes, without limitation, all rights to payment, including returned premiums, with respect to any insurance relating thereto.

Notwithstanding the foregoing, at any time, other than after the occurrence and during the continuation of a Default or an Event of Default, the Debtor may request that the Lender release its Lien on so much of the Collateral as equals the excess, if any, of the Adjusted Collateral Value of the Collateral over the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor; provided that such excess shall be released from the Custodial Account only with the consent of the Lender, which consent may be given or withheld by the Lender in its sole discretion. Should the Adjusted Collateral Value of the Collateral be less than the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, the Lender shall have the right to require the Debtor to pay to the Custodian by no later than 3:00 p.m. (Connecticut time) (i) on the date of such notice, if such notice is received before 12:00 p.m. (Connecticut time) or (ii) on the Business Day immediately following the date of notice by the Lender, if such notice is received after 12:00 p.m. (Connecticut time), the difference between (A) the then-current Adjusted Collateral Value of the Collateral and (B) the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, which payment shall be deposited by the Custodian into the Custodial Account in the form of cash or Investments. Any failure by the Debtor to make such payment shall constitute an Event of Default hereunder and under the Fundamental Documents.

In addition, the Debtor shall have the right, other than after the occurrence and during the continuation of a Default or an Event of Default, to substitute Collateral to the extent such substitution arises from normal trade activities within the Custodial Account hereunder so long as (i) the Debtor maintains the value of the Custodial Account in accordance with this Section 1,
(ii) such substituted Collateral shall be in the form of Investments, and (iii) if requested by the Lender, the Debtor shall deliver to the Lender a Supplement to Security Agreement in a form satisfactory to the Lender. The Collateral which is removed from the Custodial Account in full compliance with this paragraph shall no longer be subject to the Lien hereof without any further action on the part of the Debtor or the Lender; the Collateral which is added to the Custodial Account pursuant to such Supplement to Security Agreement shall immediately be subject to the Lien hereof without any further action on the part of the Debtor or the Lender. The Debtor agrees to pay any costs and expenses of the Lender (and its counsel) in connection with any substitution of Collateral.

-2-

2. SECURITY FOR OBLIGATIONS. The grant in Section 1 secures and the Collateral is collateral security for the prompt payment or performance in full when due, whether at stated maturity, by acceleration or otherwise of all obligations of every nature now or hereafter existing of the Debtor under the Letter of Credit Agreement and any Letter of Credit application and reimbursement agreement or other document or instrument delivered pursuant thereto, and all amendments, extensions or renewals thereof or hereof, whether for principal, interest, fees, expenses or otherwise, whether now existing or hereafter arising, voluntary or involuntary, whether or not jointly owed with others, direct or indirect, absolute or contingent, liquidated or unliquidated, and whether or not from time to time decreased or extinguished and later increased, created or incurred and all or any portion of such obligations that are paid, to the extent all or any part of such payment is avoided or recovered directly or indirectly as a preference, fraudulent transfer or otherwise, and all obligations of every nature of the Debtor now or hereafter existing under this Agreement (all such obligations being the "Secured Obligations").

3. DELIVERY OF COLLATERAL. All certificates or instruments, if any, representing or evidencing the Collateral shall be delivered to and held by the Custodian for the benefit of the Lender. At any time at which an Event of Default has occurred and is continuing under the Letter of Credit Agreement, the Lender shall have the right, subject at all times to Section 11 hereof, in its discretion and without notice to the Debtor, to transfer to or to register in the name of any of its nominees any or all of the Collateral, and may receive the income and any distributions thereon and hold the same as Collateral for the Secured Obligations, or apply the same to any of the Secured Obligations.

4. DEBTOR REMAINS LIABLE. Anything herein to the contrary notwithstanding, (a) the Debtor shall remain liable under the contracts and agreements included or relating to the Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by the Lender of any of the rights hereunder shall not release the Debtor from any of its duties or obligations under the contracts and agreements included in or relating to the Collateral, and (c) the Lender shall not have any obligation or liability under the contracts and agreements included in or relating to the Collateral by reason of this Agreement, nor shall the Lender be obligated to perform any of the obligations or duties of the Debtor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

5. REPRESENTATIONS AND WARRANTIES. The Debtor hereby represents and warrants as follows:

(a) The Debtor is duly organized and validly exists under the laws of Nebraska.

(b) The Debtor is the legal and beneficial owner of the Collateral free and clear of any liens, security interest, option or other charge or encumbrance (except liens in favor of the Custodian). No effective financing statement or other instrument similar in effect covering all or any part of the Collateral is on file in any recording

-3-

office, except such as may have been filed in favor of the Lender relating to this Agreement. Except as set forth on Schedule 2 attached hereto, the Debtor has no trade names and does not do business under any fictitious business name.

(c) The pledge and the grant of the security interest in the Collateral pursuant to this Agreement creates a valid and perfected first priority security interest in the Collateral, and all filings and other actions necessary to perfect and protect such security interest have been duly taken.

(d) No authorization, consent, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body (other than authorizations, consents, approvals already obtained, actions already taken, notices already provided and filings already made) is required (i) for the grant by the Debtor of the security interest granted hereby or for the execution, delivery or performance of this Agreement by the Debtor, (ii) for the perfection of or the exercise by the Lender of its rights and remedies provided for in this Agreement or (iii) to ensure the legality, validity, enforceability or admissibility in evidence of this Agreement in any jurisdiction in which any of the Collateral is located.

(e) Each of this Agreement and the other Fundamental Documents to which the Debtor is a party constitutes the legal, valid and binding obligation of the Debtor, enforceable against the Debtor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or other similar laws affecting the enforcement of creditors' rights generally, and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). To the knowledge of the Debtor, each Pledged Investment constitutes the legally valid and binding obligation of the party obligated to pay the same.

(f) The Debtor is deriving substantial direct and indirect benefits from the issuance of the Letters of Credit for its account under the Letter of Letter of Credit Agreement and has received good and adequate consideration for the pledge of the Collateral effected under this Agreement.

6. FURTHER ASSURANCES: SUPPLEMENTS. (a) The Debtor agrees that at any time and from time to time, at its expense, it will promptly execute and deliver all further instruments and documents, and take all further action that may be reasonably necessary or desirable, or that the Lender may request, to perfect and protect the pledges and security interests granted or purported to be granted hereby or to enable the Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, the Debtor will (i) if any Collateral shall be evidenced by a promissory note or other instrument, or if any of the Collateral shall constitute chattel paper, deliver to the Lender (or to the Custodian to hold on behalf of the Lender) such note, instrument and all original counterparts of chattel paper duly endorsed and accompanied by duly executed instruments of transfer, all in form satisfactory to the Lender and (ii) execute and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or

-4-

desirable, or that the Lender may reasonably request, to protect and preserve the pledges and security interests granted or purported to be granted hereby.

(b) The Debtor hereby authorizes the Lender to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral. A carbon, photographic or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. The Lender will promptly send the Debtor any financing or continuation statements thereto which it files without the signature of the Debtor and, except in the case of filings of copies of this Agreement as financing statements, the Lender will promptly send the Debtor the filing or recordation information with respect thereto.

(c) The Debtor will furnish to the Lender from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Lender may reasonably request, all in reasonable detail.

(d) The Debtor agrees that it will not create or permit to exist any lien, security interest or other charge or encumbrance upon or with respect to any of the Collateral except in favor of the Lender hereunder or the Custodian.

7. ADDITIONAL COVENANTS. (a) The Debtor shall maintain its organization and existence in the jurisdiction specified in Section 5(a) and shall not reincorporate or otherwise reorganize in any other jurisdiction without the prior written consent of the Lender. The Debtor shall, from the date on which each Pledged Investment was purchased, maintain (i) complete records of each Pledged Investment, including records of all payments received, interest or fees accruing or credits granted and (ii) all documentation relating thereto. In connection therewith, the Lender may (subject to the confidentiality restrictions contained in any agreement) institute procedures to permit it to confirm the balances owing in respect of any Pledged Investment. The Debtor agrees to render to the Lender such clerical and other assistance as may be reasonably requested with regard to the foregoing. If an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, promptly upon request therefor, the Debtor shall (subject to the confidentiality restrictions contained in any agreement) deliver to the Lender complete and correct copies of all documentation relating to the Pledged Investments.

(b) The Debtor shall duly fulfill in all material respects all obligations on its part to be fulfilled under or in connection with the Pledged Investments and shall do nothing to impair in any material respect the rights of the Lender therein.

(c) Following an Event of Default under the Letter of Credit Agreement (subject to Section 11 hereof), any proceeds of Collateral when first received by or on behalf of the Debtor shall be deposited by or on behalf of the Debtor in the form so received in the Custodial Account, and until so deposited shall be held in trust for and

-5-

as the Lender's property and shall not be commingled with the Debtor's or any other Person's other funds or properties.

(d) The Debtor, at its own cost and expense, will, and will cause the Custodian to, maintain satisfactory and complete records of the Collateral, including, without limitation, a record of all payments received with respect to the Collateral and all other dealings with the Collateral. Upon the occurrence and during the continuation of an Event of Default under the Letter of Credit Agreement, the Debtor will (subject to the confidentiality restrictions contained in any agreement and any applicable law) deliver and turn over to the Lender or to its representatives, or at the option of the Lender shall (subject to the confidentiality restrictions contained in any agreement) provide the Lender or its representatives with access to, at any time on demand of the Lender, copies of all the Debtor's books and records pertaining to the Collateral including, without limitation, all credit files and computer software, programs, tapes or disks relating to Pledged Investments or otherwise necessary to the collection thereof.

(e) The Debtor will comply in all material respects with all applicable statutes, rules, and regulations with respect to the Collateral or any part thereof.

(f) The Debtor will pay promptly when due all taxes, assessments and governmental charges or levies imposed upon the Collateral or in respect of its income or profits therefrom and all claims of any kind (including, without limitation, claims for labor, materials and supplies), except that no such amount need be paid if (i) such non-payment does not involve any danger of the sale, forfeiture or loss of any of the Collateral or any interest therein, (ii) the charge or levy is being contested in good faith and by proper proceedings, and (iii) the obligation to pay such amount is adequately reserved against in accordance with and to the extent required by GAAP.

(g) The Debtor will in all material respects perform and observe all the terms and provisions of the documentation relating to the Pledged Investments to be performed or observed by it, maintain the documentation relating to the Pledged Investments in full force and effect in accordance with their terms, and take all action to such end as may be from time reasonably requested by the Lender.

(h) The Debtor will advise the Lender promptly, in reasonable detail, (i) of any lien, security interest, encumbrance or claim made or asserted against any of the Collateral by any Person, other than the Custodian, and (ii) of the occurrence of any event which would have a material adverse effect on the aggregate value of the Collateral or on the pledges and security interests granted hereby.

(i) The Debtor will not sell, assign (by operation of law or otherwise), or otherwise dispose of, or grant any option with respect to, any of the Collateral, except sales not restricted by the terms of the Letter of Credit Agreement or this Agreement.

(j) The Debtor shall at all times retain Fleet National Bank as the Custodian pursuant to the Custodian Agreement.

-6-

8. LENDER APPOINTED ATTORNEY-IN-FACT. The Debtor appoints the Lender its attorney-in-fact with full authority in the place and stead of the Debtor and in the name of the Debtor or otherwise, from time to time in the Lender's discretion, after an Event of Default under the Letter of Credit Agreement has occurred and is continuing (but in all instances subject to
Section 11 hereof), to take any action and to execute any instrument that the Lender may deem necessary or advisable to accomplish the purposes of this Agreement (subject to the provisions of any applicable law), including, without limitation, to (i) ask, demand, collect, sue for, recover, compromise, receive and give acquittances and receipts for moneys due and to become due under or in connection with the Collateral, (ii) receive, endorse and collect all drafts or other instruments and documents made payable to the Debtor in connection therewith or representing any payment, dividend or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same,
(iii) file any claims or take any action or institute any proceedings which the Lender may deem to be necessary or desirable for the collection of any of the Collateral, (iv) enforce the rights of the Lender with respect to any of the Collateral and compliance with the terms and conditions of this Agreement, the Letter of Credit Agreement and the other Fundamental Documents, (v) pay or discharge taxes or Liens levied or placed upon or threatened against the Collateral, the legality or validity thereof and the amounts necessary to discharge the same to be determined by the Lender in its sole discretion, and such payments made by the Lender to become obligations of the Debtor to the Lender, due and payable in accordance with the Letter of Credit Agreement, (vi) generally sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Lender were the absolute owner thereof for all purposes, and (vii) do, at the Lender's option and the Debtor's expense, at any time, or from time to time, all acts and things that the Lender deems necessary to protect, preserve or realize upon the Collateral and the Lender's security interest therein, in order to effect the intent of this Agreement, all as fully and effectively as the Debtor might do.

9. LENDER MAY PERFORM. If the Debtor fails to perform any agreement contained herein or if a Default or an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, the Lender may at any time (but in all instances subject to Section 11 hereof) itself perform, or cause performance of, such agreement.

10. THE LENDER. (a) Neither the Lender nor any of its respective affiliates, directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or for errors in judgment, except for its or their own gross negligence, willful misconduct or bad faith.

(b) The powers conferred on the Lender hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon the Lender to exercise any such powers. Except for the exercise of reasonable care in the custody and preservation of any Collateral in its possession and accounting for moneys actually received by it hereunder, the Lender shall have no duty as to any Collateral or as to any rights pertaining thereto.

-7-

(c) The Lender shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Lender accords its own property.

11. REMEDIES UPON DEFAULT; APPLICATION OF COLLATERAL. (a) If an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, then any cash held by the Lender and all cash proceeds received by the Lender in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied to the obligations of the Debtor to the Lender as the Lender determines in its sole discretion. Any surplus of such cash or cash proceeds held by the Lender and remaining after the payment in full of all the Secured Obligations shall be paid over to the Debtor or to whomsoever may be lawfully entitled thereto.

(a) Any foreclosure upon, sale of, or exercise of rights with respect to the Collateral shall be conducted in compliance with all contractual provisions applicable to such Collateral, including but not limited to any provisions of any agreement pursuant to which any Investment arises that govern the sale or assignment thereof.

(b) Any sale of the Collateral or any part thereof shall be made in a commercially reasonable manner and in accordance with applicable law and may be made in one or more lots at public or private sale, for cash, on credit or for future delivery. The Lender and/or any of its affiliates may be a purchaser at any such sale. The Lender shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Lender may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. The Debtor shall cooperate with the Lender in all reasonable ways in order to assist the Lender in the sale and other disposition of the Collateral.

12. AMENDMENTS, ETC. No amendment of any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by the Debtor and the Lender, no waiver of any provision of this Agreement, nor consent to any departure by the Debtor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Lender, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure to exercise nor any delay in exercising on the part of the Lender of any right, power or privilege under this Agreement, shall operate as a waiver thereof; further, no single or partial exercise of any right, power or privilege under this Agreement shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

13. INDEMNITY AND EXPENSES. (a) The Debtor agrees to indemnify the Lender and each of its directors, officers, employees and agents (each an "Indemnified Person") from and against any and all claims, damages, losses, liabilities and expenses (excluding any present or future taxes, now or hereafter imposed, levied, collected, withheld or assessed), arising out of or in connection with or resulting from the Debtor's performance under this Agreement (including, without limitation, enforcement

EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES.

SECURITY AGREEMENT

SECURITY AGREEMENT (the "Agreement") dated as of April 17, 2002 between FIRST AMERICAN INSURANCE COMPANY, a corporation organized and existing under the laws of Missouri, ("First American" or "Debtor") and FLEET NATIONAL BANK, as the Lender under the below referenced Letter of Credit Agreement (the "Lender").

W I T N E S S E T H:

WHEREAS, the Lender as the issuer of Letters of Credit has entered into a Letter of Credit and Reimbursement Agreement dated as of April 17, 2002 (as such agreement may hereafter be amended or otherwise modified from time to time, being the "Letter of Credit Agreement") with Arch Reinsurance Ltd., Arch Reinsurance Company, Alternative Re Limited and First American;

WHEREAS, it is a condition precedent to the issuance of Letters of Credit by the Lender under the Letter of Credit Agreement that the Debtor shall have executed and delivered to the Lender this Agreement and pledged and granted a security interest in the Collateral, as such term is defined below, held by or on behalf of the Debtor from time to time and other rights and interests contemplated by this Agreement; and

WHEREAS, pursuant to the terms of the Custodian Agreement, the Custodian has established a Custodial Account, account #0010407670 (the "Custodial Account"), in the name of the Debtor and the Company hereby grants to the Lender a security interest in the Collateral, including the Custodial Account.

NOW, THEREFORE, in consideration of the premises and in order to induce the Lender to issue Letters of Credit for the account of the Debtor under the Letter of Credit Agreement, First American hereby agrees with the Lender as follows (all capitalized terms used herein shall have the meanings set forth in SCHEDULE 1 hereto or, if not defined therein, in the Letter of Credit Agreement):

1. GRANT OF SECURITY. The Debtor hereby pledges to the Lender and grants to the Lender for its benefit a security interest in and lien upon, all of the Debtor's right, title and interest in and to the following, in each case whether now or hereafter existing or in which the Debtor now has or hereafter acquires an interest and wherever the same may be located (collectively, the "Collateral"):

(i) The Custodial Account, including all cash held therein or credited thereto from time to time, and all securities, instruments and investments, including Investments, and other "investment property" and "financial assets," as each such term is defined in the UCC, of any kind held therein or credited thereto from time to time) (the "Pledged Investments"); and


(ii) All proceeds of, accessions to, substitutions for, and earnings on, any and all of the foregoing Collateral (including, without limitation, proceeds that constitute property of the types described in clauses (i) and (ii) above) and, to the extent not otherwise included, all payments under insurance (whether or not the Lender is the loss payee thereof), or any indemnity, warranty or guaranty, payable by reason of loss or damage to or otherwise with respect to any of the foregoing Collateral. For purposes hereof, the term "proceeds" includes whatever is receivable or received when Collateral or proceeds are sold, collected, exchanged or otherwise disposed of, whether such disposition is voluntary or involuntary, and includes, without limitation, all rights to payment, including returned premiums, with respect to any insurance relating thereto.

Notwithstanding the foregoing, at any time, other than after the occurrence and during the continuation of a Default or an Event of Default, the Debtor may request that the Lender release its Lien on so much of the Collateral as equals the excess, if any, of the Adjusted Collateral Value of the Collateral over the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor; provided that such excess shall be released from the Custodial Account only with the consent of the Lender, which consent may be given or withheld by the Lender in its sole discretion. Should the Adjusted Collateral Value of the Collateral be less than the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, the Lender shall have the right to require the Debtor to pay to the Custodian by no later than 3:00 p.m. (Connecticut time) (i) on the date of such notice, if such notice is received before 12:00 p.m. (Connecticut time) or (ii) on the Business Day immediately following notice by the Lender, if such notice is received after 12:00 p.m. (Connecticut time), the difference between the then-current Adjusted Collateral Value of the Collateral and (B) the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, which payment shall be deposited by the Custodian into the Custodial Account in the form of cash or Investments. Any failure by the Debtor to make such payment shall constitute an Event of Default hereunder and under the Fundamental Documents.

In addition, the Debtor shall have the right, other than after the occurrence and during the continuation of a Default or an Event of Default, to substitute Collateral to the extent such substitution arises from normal trade activities within the Custodial Account hereunder so long as (i) the Debtor maintains the value of the Custodial Account in accordance with this Section 1,
(ii) such substituted Collateral shall be in the form of Investments, and (iii) if requested by the Lender, the Debtor shall deliver to the Lender a Supplement to Security Agreement in a form satisfactory to the Lender. The Collateral which is removed from the Custodial Account in full compliance with this paragraph shall no longer be subject to the Lien hereof without any further action on the part of the Debtor or the Lender; the Collateral which is added to the Custodial Account pursuant to such Supplement to Security Agreement shall immediately be subject to the Lien hereof without any further action on the part of the Debtor or the Lender. The Debtor agrees to pay any costs and expenses of Lender (and its counsel) in connection with any substitution of Collateral.

-2-

2. SECURITY FOR OBLIGATIONS. The grant in Section 1 secures and the Collateral is collateral security for the prompt payment or performance in full when due, whether at stated maturity, by acceleration or otherwise of all obligations of every nature now or hereafter existing of the Debtor under the Letter of Credit Agreement and any Letter of Credit application and reimbursement agreement or other document or instrument delivered pursuant thereto, and all amendments, extensions or renewals thereof or hereof, whether for principal, interest, fees, expenses or otherwise, whether now existing or hereafter arising, voluntary or involuntary, whether or not jointly owed with others, direct or indirect, absolute or contingent, liquidated or unliquidated, and whether or not from time to time decreased or extinguished and later increased, created or incurred and all or any portion of such obligations that are paid, to the extent all or any part of such payment is avoided or recovered directly or indirectly as a preference, fraudulent transfer or otherwise, and all obligations of every nature of the Debtor now or hereafter existing under this Agreement (all such obligations being the "Secured Obligations").

3. DELIVERY OF COLLATERAL. All certificates or instruments, if any, representing or evidencing the Collateral shall be delivered to and held by the Custodian for the benefit of the Lender. At any time at which an Event of Default has occurred and is continuing under the Letter of Credit Agreement, the Lender shall have the right, subject at all times to Section 11 hereof, in its discretion and without notice to the Debtor, to transfer to or to register in the name of any of its nominees any or all of the Collateral, and may receive the income and any distributions thereon and hold the same as Collateral for the Secured Obligations, or apply the same to any of the Secured Obligations.

4. DEBTOR REMAINS LIABLE. Anything herein to the contrary notwithstanding, (a) the Debtor shall remain liable under the contracts and agreements included or relating to the Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by the Lender of any of the rights hereunder shall not release the Debtor from any of its duties or obligations under the contracts and agreements included in or relating to the Collateral, and (c) the Lender shall not have any obligation or liability under the contracts and agreements included in or relating to the Collateral by reason of this Agreement, nor shall the Lender be obligated to perform any of the obligations or duties of the Debtor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

5. REPRESENTATIONS AND WARRANTIES. The Debtor hereby represents and warrants as follows:

(a) The Debtor is duly organized and validly exists under the laws of Missouri.

(b) The Debtor is the legal and beneficial owner of the Collateral free and clear of any liens, security interest, option or other charge or encumbrance (except liens in favor of the Custodian). No effective financing statement or other instrument similar in effect covering all or any part of the Collateral is on file in any recording office, except

-3-

such as may have been filed in favor of the Lender relating to this Agreement. Except as set forth on Schedule 2 attached hereto, the Debtor has no trade names and does not do business under any fictitious business name.

(c) The pledge and the grant of the security interest in the Collateral pursuant to this Agreement creates a valid and perfected first priority security interest in the Collateral, and all filings and other actions necessary to perfect and protect such security interest have been duly taken.

(d) No authorization, consent, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body (other than authorizations, consents, approvals already obtained, actions already taken, notices already provided and filings already made) is required (i) for the grant by the Debtor of the security interest granted hereby or for the execution, delivery or performance of this Agreement by the Debtor, (ii) for the perfection of or the exercise by the Lender of its rights and remedies provided for in this Agreement or (iii) to ensure the legality, validity, enforceability or admissibility in evidence of this Agreement in any jurisdiction in which any of the Collateral is located.

(e) Each of this Agreement and the other Fundamental Documents to which the Debtor is a party constitutes the legal, valid and binding obligation of the Debtor, enforceable against the Debtor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or other similar laws affecting the enforcement of creditors' rights generally, and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). To the knowledge of the Debtor, each Pledged Investment constitutes the legally valid and binding obligation of the party obligated to pay the same.

(f) The Debtor is deriving substantial direct and indirect benefits from the issuance of the Letters of Credit for its account under the Letter of Letter of Credit Agreement and has received good and adequate consideration for the pledge of the Collateral effected under this Agreement.

6. FURTHER ASSURANCES: SUPPLEMENTS. (a) The Debtor agrees that at any time and from time to time, at its expense, it will promptly execute and deliver all further instruments and documents, and take all further action that may be reasonably necessary or desirable, or that the Lender may request, to perfect and protect the pledges and security interests granted or purported to be granted hereby or to enable the Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, the Debtor will (i) if any Collateral shall be evidenced by a promissory note or other instrument, or if any of the Collateral shall constitute chattel paper, deliver to the Lender (or to the Custodian to hold on behalf of the Lender) such note, instrument and all original counterparts of chattel paper duly endorsed and accompanied by duly executed instruments of transfer, all in form satisfactory to the Lender and (ii) execute and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or

-4-

desirable, or that the Lender may reasonably request, to protect and preserve the pledges and security interests granted or purported to be granted hereby.

(a) The Debtor hereby authorizes the Lender to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral. A carbon, photographic or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. The Lender will promptly send the Debtor any financing or continuation statements thereto which it files without the signature of the Debtor and, except in the case of filings of copies of this Agreement as financing statements, the Lender will promptly send the Debtor the filing or recordation information with respect thereto.

(b) The Debtor will furnish to the Lender from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Lender may reasonably request, all in reasonable detail.

(c) The Debtor agrees that it will not create or permit to exist any lien, security interest or other charge or encumbrance upon or with respect to any of the Collateral except in favor of the Lender hereunder or the Custodian.

7. ADDITIONAL COVENANTS. (a) The Debtor shall maintain its organization and existence in the jurisdiction specified in Section 5(a) and shall not reincorporate or otherwise reorganize in any other jurisdiction without the prior written consent of the Lender. The Debtor shall, from the date on which each Pledged Investment was purchased, maintain (i) complete records of each Pledged Investment, including records of all payments received, interest or fees accruing or credits granted and (ii) all documentation relating thereto. In connection therewith, the Lender may (subject to the confidentiality restrictions contained in any agreement) institute procedures to permit it to confirm the balances owing in respect of any Pledged Investment. The Debtor agrees to render to the Lender such clerical and other assistance as may be reasonably requested with regard to the foregoing. If an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, promptly upon request therefor, the Debtor shall (subject to the confidentiality restrictions contained in any agreement) deliver to the Lender complete and correct copies of all documentation relating to the Pledged Investments.

(a) The Debtor shall duly fulfill in all material respects all obligations on its part to be fulfilled under or in connection with the Pledged Investments and shall do nothing to impair in any material respect the rights of the Lender therein.

(b) Following an Event of Default under the Letter of Credit Agreement (subject to Section 11 hereof), any proceeds of Collateral when first received by or on behalf of the Debtor shall be deposited by or on behalf of the Debtor in the form so received in the Custodial Account, and until so deposited shall be held in trust for and as

-5-

the Lender's property and shall not be commingled with the Debtor's or any other Person's other funds or properties.

(c) The Debtor, at its own cost and expense, will, and will cause the Custodian to, maintain satisfactory and complete records of the Collateral, including, without limitation, a record of all payments received with respect to the Collateral and all other dealings with the Collateral. Upon the occurrence and during the continuation of an Event of Default under the Letter of Credit Agreement, the Debtor will (subject to the confidentiality restrictions contained in any agreement and any applicable law) deliver and turn over to the Lender or to its representatives, or at the option of the Lender shall (subject to the confidentiality restrictions contained in any agreement) provide the Lender or its representatives with access to, at any time on demand of the Lender, copies of all the Debtor's books and records pertaining to the Collateral including, without limitation, all credit files and computer software, programs, tapes or disks relating to Pledged Investments or otherwise necessary to the collection thereof.

(d) The Debtor will comply in all material respects with all applicable statutes, rules, and regulations with respect to the Collateral or any part thereof.

(e) The Debtor will pay promptly when due all taxes, assessments and governmental charges or levies imposed upon the Collateral or in respect of its income or profits therefrom and all claims of any kind (including, without limitation, claims for labor, materials and supplies), except that no such amount need be paid if (i) such non-payment does not involve any danger of the sale, forfeiture or loss of any of the Collateral or any interest therein, (ii) the charge or levy is being contested in good faith and by proper proceedings, and (iii) the obligation to pay such amount is adequately reserved against in accordance with and to the extent required by GAAP.

(f) The Debtor will in all material respects perform and observe all the terms and provisions of the documentation relating to the Pledged Investments to be performed or observed by it, maintain the documentation relating to the Pledged Investments in full force and effect in accordance with their terms, and take all action to such end as may be from time reasonably requested by the Lender.

(g) The Debtor will advise the Lender promptly, in reasonable detail, (i) of any lien, security interest, encumbrance or claim made or asserted against any of the Collateral by any Person, other than the Custodian, and (ii) of the occurrence of any event which would have a material adverse effect on the aggregate value of the Collateral or on the pledges and security interests granted hereby.

(h) The Debtor will not sell, assign (by operation of law or otherwise), or otherwise dispose of, or grant any option with respect to, any of the Collateral, except sales not restricted by the terms of the Letter of Credit Agreement or this Agreement.

(i) The Debtor shall at all times retain Fleet National Bank as the Custodian pursuant to the Custodian Agreement.

-6-

8. LENDER APPOINTED ATTORNEY-IN-FACT. The Debtor appoints the Lender its attorney-in-fact with full authority in the place and stead of the Debtor and in the name of the Debtor or otherwise, from time to time in the Lender's discretion, after an Event of Default under the Letter of Credit Agreement has occurred and is continuing (but in all instances subject to
Section 11 hereof), to take any action and to execute any instrument that the Lender may deem necessary or advisable to accomplish the purposes of this Agreement (subject to the provisions of any applicable law), including, without limitation, to (i) ask, demand, collect, sue for, recover, compromise, receive and give acquittances and receipts for moneys due and to become due under or in connection with the Collateral, (ii) receive, endorse and collect all drafts or other instruments and documents made payable to the Debtor in connection therewith or representing any payment, dividend or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same,

9. LENDER MAY PERFORM. If the Debtor fails to perform any agreement contained herein or if a Default or an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, the Lender may at any time (but in all instances subject to Section 11 hereof) itself perform, or cause performance of, such agreement.

10. THE LENDER. (a) Neither the Lender nor any of its respective affiliates, directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or for errors in judgment, except for its or their own gross negligence, willful misconduct or bad faith.

(b) The powers conferred on the Lender hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon the Lender to exercise any such powers. Except for the exercise of reasonable care in the custody and preservation of any Collateral in its possession and accounting for moneys actually received by it hereunder, the Lender shall have no duty as to any Collateral or as to any rights pertaining thereto.

-7-

(c) The Lender shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Lender accords its own property.

11. REMEDIES UPON DEFAULT; APPLICATION OF COLLATERAL. (a) If an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, then any cash held by the Lender and all cash proceeds received by the Lender in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied to the obligations of the Debtor to the Lender as the Lender determines in its sole discretion. Any surplus of such cash or cash proceeds held by the Lender and remaining after the payment in full of all the Secured Obligations shall be paid over to the Debtor or to whomsoever may be lawfully entitled thereto.

No amendment of any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by the Debtor and the Lender, no waiver of any provision of this Agreement, nor consent to any departure by the Debtor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Lender, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure to exercise nor any delay in exercising on the part of the Lender of any right, power or privilege under this Agreement, shall operate as a waiver thereof; further, no single or partial exercise of any right, power or privilege under this Agreement shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(ii) be binding upon the Debtor and its successors and assigns, including but not limited to any trustee or examiner for the Debtor under the Bankruptcy Code or receiver for the assets of the Debtor under any rehabilitation or insolvency law, and (iii) inure, together with the rights and remedies of the Lender hereunder, to the benefit of the Lender and its respective successors,

Unless otherwise defined herein or in the Letter of Credit Agreement, terms used in Article 8 and/or 9 of the Uniform Commercial Code in the State of Connecticut are used herein as therein defined.

20. NO PETITION IN BANKRUPTCY. Each of the parties to this Agreement severally and not jointly, hereby covenants and agrees that, prior to the date which is one year and one day after the payment or expiration in full of all outstanding Letters of Credit, it will not institute against, or join any other Person in instituting against, the Debtor any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or other similar proceeding.

21. WAIVER OF JURY TRIAL. THE DEBTOR AND THE LENDER MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER FUNDAMENTAL DOCUMENTS CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING, WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF THE LENDER RELATING TO THE ADMINISTRATION OF THIS AGREEMENT OR ENFORCEMENT OF THE FUNDAMENTAL DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.

-10-

EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. EACH OBLIGOR CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR THE LENDER TO ENTER INTO THIS AGREEMENT AND THE OTHER FUNDAMENTAL DOCUMENTS. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

22. JURISDICTION; CONSENT TO SERVICE OF PROCESS.

(a) The Debtor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement, the Letter of Credit Agreement or the other Fundamental Documents in any Connecticut State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

-11-

provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

SECURITY AGREEMENT

SECURITY AGREEMENT (the "Agreement") dated as of April 17, 2002 between ARCH REINSURANCE LTD., a corporation organized and existing under the laws of Bermuda, ("Reinsurance" or "Debtor") and FLEET NATIONAL BANK, as the Lender under the below referenced Letter of Credit Agreement (the "Lender").

W I T N E S S E T H:

WHEREAS, the Lender as the issuer of Letters of Credit has entered into a Letter of Credit and Reimbursement Agreement dated as of April 17, 2002 (as such agreement may hereafter be amended or otherwise modified from time to time, being the "Letter of Credit Agreement") with Alternative Re Limited, Reinsurance, Arch Reinsurance Company and First American Insurance Company;

WHEREAS, it is a condition precedent to the issuance of Letters of Credit by the Lender under the Letter of Credit Agreement that the Debtor shall have executed and delivered to the Lender this Agreement and pledged and granted a security interest in the Collateral, as such term is defined below, held by or on behalf of the Debtor from time to time and other rights and interests contemplated by this Agreement; and

WHEREAS, pursuant to the terms of the Custodian Agreement, the Custodian has established a Custodial Account, account #0010406870 (the "Custodial Account"), in the name of the Debtor and the Company hereby grants to the Lender a security interest in the Collateral, including the Custodial Account.

NOW, THEREFORE, in consideration of the premises and in order to induce the Lender to issue Letters of Credit for the account of the Debtor under the Letter of Credit Agreement, Reinsurance hereby agrees with the Lender as follows (all capitalized terms used herein shall have the meanings set forth in SCHEDULE 1 hereto or, if not defined therein, in the Letter of Credit Agreement):

1. GRANT OF SECURITY. The Debtor hereby pledges and charges to the Lender and grants to the Lender for its benefit a security interest in and lien upon, all of the Debtor's right, title and interest in and to the following, in each case whether now or hereafter existing or in which the Debtor now has or hereafter acquires an interest and wherever the same may be located (collectively, the "Collateral"):

(i) The Custodial Account, including all cash held therein or credited thereto from time to time, and all securities, instruments and investments, including Investments, and other "investment property" and "financial assets," as each such term is defined in the UCC, of any kind held therein or credited thereto from time to time) (the "Pledged Investments");

(ii) All proceeds of, accessions to, substitutions for, and earnings on, any and all of the foregoing Collateral (including, without limitation, proceeds that constitute property of the types described in clauses (i) and (ii) above) and, to


the extent not otherwise included, all payments under insurance (whether or not the Lender is the loss payee thereof), or any indemnity, warranty or guaranty, payable by reason of loss or damage to or otherwise with respect to any of the foregoing Collateral. For purposes hereof, the term "proceeds" includes whatever is receivable or received when Collateral or proceeds are sold, collected, exchanged or otherwise disposed of, whether such disposition is voluntary or involuntary, and includes, without limitation, all rights to payment, including returned premiums, with respect to any insurance relating thereto.

Notwithstanding the foregoing, at any time, other than after the occurrence and during the continuation of a Default or an Event of Default, the Debtor may request that the Lender release its Lien on so much of the Collateral as equals the excess, if any, of the Adjusted Collateral Value of the Collateral over the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor; provided that such excess shall be released from the Custodial Account only with the consent of the Lender, which consent may be given or withheld by the Lender in its sole discretion. Should the Adjusted Collateral Value of the Collateral be less than the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, the Lender shall have the right to require the Debtor to pay to the Custodian by no later than 3:00 p.m. (Connecticut time) (i) on the date of such notice, if such notice is received before 12:00 p.m. (Connecticut time) or (ii) on the Business Day immediately following notice by the Lender, if such notice is received after 12:00 p.m. (Connecticut time), the difference between the then-current Adjusted Collateral Value of the Collateral and (B) the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, which payment shall be deposited by the Custodian into the Custodial Account in the form of cash or Investments. Any failure by the Debtor to make such payment shall constitute an Event of Default hereunder and under the Fundamental Documents.

In addition, the Debtor shall have the right, other than after the occurrence and during the continuation of a Default or an Event of Default, to substitute Collateral to the extent such substitution arises from normal trade activities within the Custodial Account hereunder so long as (i) the Debtor maintains the value of the Custodial Account in accordance with this Section 1,
(ii) such substituted Collateral shall be in the form of Investments, and (iii) if requested by the Lender, the Debtor shall deliver to the Lender a Supplement to Security Agreement in a form satisfactory to the Lender. The Collateral which is removed from the Custodial Account in full compliance with this paragraph shall no longer be subject to the Lien hereof without any further action on the part of the Debtor or the Lender; the Collateral which is added to the Custodial Account pursuant to such Supplement to Security Agreement shall immediately be subject to the Lien hereof without any further action on the part of the Debtor or the Lender. The Debtor agrees to pay any costs and expenses of the Lender (and its counsel) in connection with any substitution of Collateral.

2. SECURITY FOR OBLIGATIONS. The grant in Section 1 secures and the Collateral is collateral security for the prompt payment or performance in full when

-2-

due, whether at stated maturity, by acceleration or otherwise of all obligations of every nature now or hereafter existing of the Debtor under the Letter of Credit Agreement and any Letter of Credit application and reimbursement agreement or other document or instrument delivered pursuant thereto, and all amendments, extensions or renewals thereof or hereof, whether for principal, interest, fees, expenses or otherwise, whether now existing or hereafter arising, voluntary or involuntary, whether or not jointly owed with others, direct or indirect, absolute or contingent, liquidated or unliquidated, and whether or not from time to time decreased or extinguished and later increased, created or incurred and all or any portion of such obligations that are paid, to the extent all or any part of such payment is avoided or recovered directly or indirectly as a preference, fraudulent transfer or otherwise, and all obligations of every nature of the Debtor now or hereafter existing under this Agreement (all such obligations being the "Secured Obligations").

3. DELIVERY OF COLLATERAL. All certificates or instruments, if any, representing or evidencing the Collateral shall be delivered to and held by the Custodian for the benefit of the Lender. At any time at which an Event of Default has occurred and is continuing under the Letter of Credit Agreement, the Lender shall have the right, subject at all times to Section 11 hereof, in its discretion and without notice to the Debtor, to transfer to or to register in the name of any of its nominees any or all of the Collateral, and may receive the income and any distributions thereon and hold the same as Collateral for the Secured Obligations, or apply the same to any of the Secured Obligations.

4. DEBTOR REMAINS LIABLE. Anything herein to the contrary notwithstanding, (a) the Debtor shall remain liable under the contracts and agreements included or relating to the Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by the Lender of any of the rights hereunder shall not release the Debtor from any of its duties or obligations under the contracts and agreements included in or relating to the Collateral, and (c) the Lender shall not have any obligation or liability under the contracts and agreements included in or relating to the Collateral by reason of this Agreement, nor shall the Lender be obligated to perform any of the obligations or duties of the Debtor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

5. REPRESENTATIONS AND WARRANTIES. The Debtor hereby represents and warrants as follows:

(a) The Debtor is duly organized and validly exists under the laws of Bermuda.

(b) The Debtor is the legal and beneficial owner of the Collateral free and clear of any liens, security interest, option or other charge or encumbrance (except liens in favor of the Custodian). No effective financing statement or other instrument similar in effect covering all or any part of the Collateral is on file in any recording office, except such as may have been filed in favor of the Lender relating to this

-3-

Agreement. Except as set forth on Schedule 2 attached hereto, the Debtor has no trade names and does not do business under any fictitious business name.

(c) The pledge and the grant of the security interest in the Collateral pursuant to this Agreement creates a valid and perfected first priority security interest in the Collateral, and all filings and other actions necessary to perfect and protect such security interest have been duly taken.

(d) No authorization, consent, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body (other than authorizations, consents, approvals already obtained, actions already taken, notices already provided and filings already made) is required (i) for the grant by the Debtor of the security interest granted hereby or for the execution, delivery or performance of this Agreement by the Debtor, (ii) for the perfection of or the exercise by the Lender of its rights and remedies provided for in this Agreement or (iii) to ensure the legality, validity, enforceability or admissibility in evidence of this Agreement in any jurisdiction in which any of the Collateral is located.

(e) Each of this Agreement and the other Fundamental Documents to which the Debtor is a party constitutes the legal, valid and binding obligation of the Debtor, enforceable against the Debtor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or other similar laws affecting the enforcement of creditors' rights generally, and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). To the knowledge of the Debtor, each Pledged Investment constitutes the legally valid and binding obligation of the party obligated to pay the same.

(f) The Debtor is deriving substantial direct and indirect benefits from the issuance of the Letters of Credit for its account under the Letter of Letter of Credit Agreement and has received good and adequate consideration for the pledge of the Collateral effected under this Agreement.

6. FURTHER ASSURANCES: SUPPLEMENTS. (a) The Debtor agrees that at any time and from time to time, at its expense, it will promptly execute and deliver all further instruments and documents, and take all further action that may be reasonably necessary or desirable, or that the Lender may request, to perfect and protect the pledges and charges and security interests granted or purported to be granted hereby or to enable the Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, the Debtor will (i) if any Collateral shall be evidenced by a promissory note or other instrument, or if any of the Collateral shall constitute chattel paper, deliver to the Lender (or to the Custodian to hold on behalf of the Lender) such note, instrument and all original counterparts of chattel paper duly endorsed and accompanied by duly executed instruments of transfer, all in form satisfactory to the Lender and
(ii) execute and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be

-4-

necessary or desirable, or that the Lender may reasonably request, to protect and preserve the pledges and charges and security interests granted or purported to be granted hereby.

(a) The Debtor hereby authorizes the Lender to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral. A carbon, photographic or other reproduction of this Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. The Lender will promptly send the Debtor any financing or continuation statements thereto which it files without the signature of the Debtor and, except in the case of filings of copies of this Agreement as financing statements, the Lender will promptly send the Debtor the filing or recordation information with respect thereto.

(b) The Debtor will furnish to the Lender from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Lender may reasonably request, all in reasonable detail.

(c) The Debtor agrees that it will not create or permit to exist any lien, security interest or other charge or encumbrance upon or with respect to any of the Collateral except in favor of the Lender hereunder or the Custodian.

7. ADDITIONAL COVENANTS. (a) The Debtor shall maintain its organization and existence in the jurisdiction specified in Section 5(a) and shall not reincorporate or otherwise reorganize in any other jurisdiction without the prior written consent of the Lender. The Debtor shall, from the date on which each Pledged Investment was purchased, maintain (i) complete records of each Pledged Investment, including records of all payments received, interest or fees accruing or credits granted and (ii) all documentation relating thereto. In connection therewith, the Lender may (subject to the confidentiality restrictions contained in any agreement) institute procedures to permit it to confirm the balances owing in respect of any Pledged Investment. The Debtor agrees to render to the Lender such clerical and other assistance as may be reasonably requested with regard to the foregoing. If an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, promptly upon request therefor, the Debtor shall (subject to the confidentiality restrictions contained in any agreement) deliver to the Lender complete and correct copies of all documentation relating to the Pledged Investments.

(a) The Debtor shall duly fulfill in all material respects all obligations on its part to be fulfilled under or in connection with the Pledged Investments and shall do nothing to impair in any material respect the rights of the Lender therein.

(b) Following an Event of Default under the Letter of Credit Agreement (subject to Section 11 hereof), any proceeds of Collateral when first received by or on behalf of the Debtor shall be deposited by or on behalf of the Debtor in the form so received in the Custodial Account, and until so deposited shall be held in trust for and

-5-

as the Lender's property and shall not be commingled with the Debtor's or any other Person's other funds or properties.

(c) The Debtor, at its own cost and expense, will, and will cause the Custodian to, maintain satisfactory and complete records of the Collateral, including, without limitation, a record of all payments received with respect to the Collateral and all other dealings with the Collateral.

9. LENDER MAY PERFORM. If the Debtor fails to perform any agreement contained herein or if a Default or an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, the Lender may at any time (but in all instances subject to Section 11 hereof) itself perform, or cause performance of, such agreement.

10. THE LENDER.

-7-

(ii) be binding upon the Debtor and its successors and assigns, including but not limited to any trustee or examiner for the Debtor under the Bankruptcy Code or receiver for the assets of the Debtor under any rehabilitation or insolvency law, and (iii) inure, together with the rights and remedies of the Lender hereunder, to the benefit of the Lender and its respective successors,

19. GOVERNING LAW; TERMS.

Unless otherwise defined herein or in the Letter of Credit Agreement, terms used in Article 8 and/or 9 of the Uniform Commercial Code in the State of Connecticut are used herein as therein defined.

20. NO PETITION IN BANKRUPTCY. Each of the parties to this Agreement severally and not jointly, hereby covenants and agrees that, prior to the date which is one year and one day after the payment or expiration in full of all outstanding Letters of Credit, it will not institute against, or join any other Person in instituting against, the Debtor any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or other similar proceeding.

-10-

EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. EACH OBLIGOR CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER.

22. JURISDICTION; CONSENT TO SERVICE OF PROCESS.

SECURITY AGREEMENT

SECURITY AGREEMENT (the "Agreement") dated as of April 17, 2002 between ALTERNATIVE RE LIMITED, a corporation organized and existing under the laws of Bermuda, ("Alternative" or "Debtor") and FLEET NATIONAL BANK, as the Lender under the below referenced Letter of Credit Agreement (the "Lender").

W I T N E S S E T H:

WHEREAS, the Lender as the issuer of Letters of Credit has entered into a Letter of Credit and Reimbursement Agreement dated as of April 17, 2002 (as such agreement may hereafter be amended or otherwise modified from time to time, being the "Letter of Credit Agreement") with Arch Reinsurance, Ltd., Arch Reinsurance Company, Alternative and First American Insurance Company;

WHEREAS, it is a condition precedent to the issuance of Letters of Credit by the Lender under the Letter of Credit Agreement that the Debtor shall have executed and delivered to the Lender this Agreement and pledged and granted a security interest in the Collateral, as such term is defined below, held by or on behalf of the Debtor from time to time and other rights and interests contemplated by this Agreement; and

WHEREAS, pursuant to the terms of the Custodian Agreement, the Custodian has established a Custodial Account, account #0010405070 (the "Custodial Account"), in the name of the Debtor and the Company hereby grants to the Lender a security interest in the Collateral, including the Custodial Account.

NOW, THEREFORE, in consideration of the premises and in order to induce the Lender to issue Letters of Credit for the account of the Debtor under the Letter of Credit Agreement, Reinsurance hereby agrees with the Lender as follows (all capitalized terms used herein shall have the meanings set forth in SCHEDULE 1 hereto or, if not defined therein, in the Letter of Credit Agreement):

1. GRANT OF SECURITY. The Debtor hereby pledges and charges to the Lender and grants to the Lender for its benefit a security interest in and lien upon, all of the Debtor's right, title and interest in and to the following, in each case whether now or hereafter existing or in which the Debtor now has or hereafter acquires an interest and wherever the same may be located (collectively, the "Collateral"):

(i) The Custodial Account, including all cash held therein or credited thereto from time to time, and all securities, instruments and investments, including Investments, and other "investment property" and "financial assets," as each such term is defined in the UCC, of any kind held therein or credited thereto from time to time) (the "Pledged Investments");

(ii) All proceeds of, accessions to, substitutions for, and earnings on, any and all of the foregoing Collateral (including, without limitation, proceeds


that constitute property of the types described in clauses (i) and (ii) above) and, to the extent not otherwise included, all payments under insurance (whether or not the Lender is the loss payee thereof), or any indemnity, warranty or guaranty, payable by reason of loss or damage to or otherwise with respect to any of the foregoing Collateral. For purposes hereof, the term "proceeds" includes whatever is receivable or received when Collateral or proceeds are sold, collected, exchanged or otherwise disposed of, whether such disposition is voluntary or involuntary, and includes, without limitation, all rights to payment, including returned premiums, with respect to any insurance relating thereto.

Notwithstanding the foregoing, at any time, other than after the occurrence and during the continuation of a Default or an Event of Default, the Debtor may request that the Lender release its Lien on so much of the Collateral as equals the excess, if any, of the Adjusted Collateral Value of the Collateral over the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor; provided that such excess shall be released from the Custodial Account only with the consent of the Lender, which consent may be given or withheld by the Lender in its sole discretion. Should the Adjusted Collateral Value of the Collateral be less than the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, the Lender shall have the right to require the Debtor to pay to the Custodian by no later than 3:00 p.m. (Connecticut time) (i) on the date of such notice, if such notice is received before 12:00 p.m. (Connecticut time) or (ii) on the Business Day immediately following notice by the Lender, if such notice is received after 12:00 p.m. (Connecticut time), the difference between the then-current Adjusted Collateral Value of the Collateral and (B) the sum of all amounts then outstanding with respect to (x) Letter of Credit Obligations of the Debtor and (y) Reimbursement Obligations of the Debtor, which payment shall be deposited by the Custodian into the Custodial Account in the form of cash or Investments. Any failure by the Debtor to make such payment shall constitute an Event of Default hereunder and under the Fundamental Documents.

In addition, the Debtor shall have the right, other than after the occurrence and during the continuation of a Default or an Event of Default, to substitute Collateral to the extent such substitution arises from normal trade activities within the Custodial Account hereunder so long as (i) the Debtor maintains the value of the Custodial Account in accordance with this Section 1,
(ii) such substituted Collateral shall be in the form of Investments, and (iii) if requested by the Lender, the Debtor shall deliver to the Lender a Supplement to Security Agreement in a form satisfactory to the Lender. The Collateral which is removed from the Custodial Account in full compliance with this paragraph shall no longer be subject to the Lien hereof without any further action on the part of the Debtor or the Lender; the Collateral which is added to the Custodial Account pursuant to such Supplement to Security Agreement shall immediately be subject to the Lien hereof without any further action on the part of the Debtor or the Lender. The Debtor agrees to pay any costs and expenses of the Lender (and its counsel) in connection with any substitution of Collateral.

-2-

2. SECURITY FOR OBLIGATIONS. The grant in Section 1 secures and the Collateral is collateral security for the prompt payment or performance in full when due, whether at stated maturity, by acceleration or otherwise of all obligations of every nature now or hereafter existing of the Debtor under the Letter of Credit Agreement and any Letter of Credit application and reimbursement agreement or other document or instrument delivered pursuant thereto, and all amendments, extensions or renewals thereof or hereof, whether for principal, interest, fees, expenses or otherwise, whether now existing or hereafter arising, voluntary or involuntary, whether or not jointly owed with others, direct or indirect, absolute or contingent, liquidated or unliquidated, and whether or not from time to time decreased or extinguished and later increased, created or incurred and all or any portion of such obligations that are paid, to the extent all or any part of such payment is avoided or recovered directly or indirectly as a preference, fraudulent transfer or otherwise, and all obligations of every nature of the Debtor now or hereafter existing under this Agreement (all such obligations being the "Secured Obligations").

3. DELIVERY OF COLLATERAL. All certificates or instruments, if any, representing or evidencing the Collateral shall be delivered to and held by the Custodian for the benefit of the Lender. At any time at which an Event of Default has occurred and is continuing under the Letter of Credit Agreement, the Lender shall have the right, subject at all times to Section 11 hereof, in its discretion and without notice to the Debtor, to transfer to or to register in the name of any of its nominees any or all of the Collateral, and may receive the income and any distributions thereon and hold the same as Collateral for the Secured Obligations, or apply the same to any of the Secured Obligations.

4. DEBTOR REMAINS LIABLE. Anything herein to the contrary notwithstanding, (a) the Debtor shall remain liable under the contracts and agreements included or relating to the Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by the Lender of any of the rights hereunder shall not release the Debtor from any of its duties or obligations under the contracts and agreements included in or relating to the Collateral, and (c) the Lender shall not have any obligation or liability under the contracts and agreements included in or relating to the Collateral by reason of this Agreement, nor shall the Lender be obligated to perform any of the obligations or duties of the Debtor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

5. REPRESENTATIONS AND WARRANTIES. The Debtor hereby represents and warrants as follows:

(a) The Debtor is duly organized and validly exists under the laws of Bermuda.

(b) The Debtor is the legal and beneficial owner of the Collateral free and clear of any liens, security interest, option or other charge or encumbrance (except liens in favor of the Custodian). No effective financing statement or other instrument similar in effect covering all or any part of the Collateral is on file in any recording

-3-

office, except such as may have been filed in favor of the Lender relating to this Agreement. Except as set forth on Schedule 2 attached hereto, the Debtor has no trade names and does not do business under any fictitious business name.

(c) The pledge and the grant of the security interest in the Collateral pursuant to this Agreement creates a valid and perfected first priority security interest in the Collateral, and all filings and other actions necessary to perfect and protect such security interest have been duly taken.

(d) No authorization, consent, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body (other than authorizations, consents, approvals already obtained, actions already taken, notices already provided and filings already made) is required (i) for the grant by the Debtor of the security interest granted hereby or for the execution, delivery or performance of this Agreement by the Debtor, (ii) for the perfection of or the exercise by the Lender of its rights and remedies provided for in this Agreement or (iii) to ensure the legality, validity, enforceability or admissibility in evidence of this Agreement in any jurisdiction in which any of the Collateral is located.

(e) Each of this Agreement and the other Fundamental Documents to which the Debtor is a party constitutes the legal, valid and binding obligation of the Debtor, enforceable against the Debtor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or other similar laws affecting the enforcement of creditors' rights generally, and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). To the knowledge of the Debtor, each Pledged Investment constitutes the legally valid and binding obligation of the party obligated to pay the same.

(f) The Debtor is deriving substantial direct and indirect benefits from the issuance of the Letters of Credit for its account under the Letter of Letter of Credit Agreement and has received good and adequate consideration for the pledge of the Collateral effected under this Agreement.

The Debtor agrees to render to the Lender such clerical and other assistance as may be reasonably requested with regard to the foregoing.

(d) The Debtor will comply in all material respects with all applicable statutes, rules, and regulations with respect to the Collateral or any part thereof.

(e) The Debtor will pay promptly when due all taxes, assessments and governmental charges or levies imposed upon the Collateral or in respect of its income or profits therefrom and all claims of any kind (including, without limitation, claims for labor, materials and supplies), except that no such amount need be paid if (i) such non-payment does not involve any danger of the sale, forfeiture or loss of any of the Collateral or any interest therein, (ii) the charge or levy is being contested in good faith and by proper proceedings, and (iii) the obligation to pay such amount is adequately reserved against in accordance with and to the extent required by GAAP.

(f) The Debtor will in all material respects perform and observe all the terms and provisions of the documentation relating to the Pledged Investments to be performed or observed by it, maintain the documentation relating to the Pledged Investments in full force and effect in accordance with their terms, and take all action to such end as may be from time reasonably requested by the Lender.

Section 11 hereof), to take any action and to execute any instrument that the Lender may deem necessary or advisable to accomplish the purposes of this Agreement (subject to the provisions of any applicable law), including, without limitation, to (i) ask, demand, collect, sue for, recover, compromise, receive and give acquittances and receipts for moneys due and to become due under or in connection with the Collateral, (ii) receive, endorse and collect all drafts or other instruments and documents made payable to the Debtor in connection therewith or representing any payment, dividend or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same,

9. LENDER MAY PERFORM. If the Debtor fails to perform any agreement contained herein or if a Default or an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, the Lender may at any time (but in all instances subject to Section 11 hereof) itself perform, or cause performance of, such agreement.

10. THE LENDER. (a) Neither the Lender nor any of its respective affiliates, directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or for errors in judgment, except for its or their own gross negligence, willful misconduct or bad faith.

(b) The powers conferred on the Lender hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon the Lender to exercise any such powers. Except for the exercise of reasonable care in the custody and preservation of any Collateral in its possession and accounting for moneys actually received by it hereunder, the Lender shall have no duty as to any Collateral or as to any rights pertaining thereto.

-7-

(c) The Lender shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Lender accords its own property.

11. REMEDIES UPON DEFAULT; APPLICATION OF COLLATERAL. (a) If an Event of Default under the Letter of Credit Agreement shall have occurred and be continuing, then any cash held by the Lender and all cash proceeds received by the Lender in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied to the obligations of the Debtor to the Lender as the Lender determines in its sole discretion. Any surplus of such cash or cash proceeds held by the Lender and remaining after the payment in full of all the Secured Obligations shall be paid over to the Debtor or to whomsoever may be lawfully entitled thereto.

The Lender and/or any of its affiliates may be a purchaser at any such sale. The Lender shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Lender may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. The Debtor shall cooperate with the Lender in all reasonable ways in order to assist the Lender in the sale and other disposition of the Collateral.

12. AMENDMENTS, ETC. No amendment of any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by the Debtor and the Lender, no waiver of any provision of this Agreement, nor consent to any departure by the Debtor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Lender, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure to exercise nor any delay in exercising on the part of the Lender of any right, power or privilege under this Agreement, shall operate as a waiver thereof; further, no single or partial exercise of any right, power or privilege under this Agreement shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(iv) the failure by the Debtor to perform or observe any of the provisions hereof or (v) any action taken by the Lender pursuant to Section 6 or 9 hereof.

16. NO WAIVER; CUMULATIVE REMEDIES. The Lender shall not by any act, delay, omission or otherwise be deemed to have waived any of its rights or remedies hereunder, and no waiver shall be valid unless in writing and signed by the Lender. A waiver by the Lender of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Lender would otherwise have on any future occasion.

17. CONTINUING SECURITY INTEREST. This Agreement shall create a continuing security interest in the Collateral and shall (i) remain in full force and effect until the payment in full of the other Secured Obligations,
(ii) be binding upon the Debtor and its successors and assigns, including but not limited to any trustee or examiner for the Debtor under the Bankruptcy Code or receiver for the assets of the Debtor under any rehabilitation or insolvency law, and (iii) inure, together with the rights and remedies of the Lender hereunder, to the benefit of the Lender and its respective successors,

-9-

transferees and assigns. Upon the payment in full of the Secured Obligations, the Debtor shall be entitled to the return, upon its request and at its expense, of such of the Collateral as shall not have been sold or otherwise applied pursuant to the terms hereof, at which time the Lender shall, at the expense and request of the Debtor, reassign and deliver to the Debtor, or to such Person or Persons as may be lawfully entitled thereto, against receipt, such of the Collateral (if any) as shall not have been sold or otherwise applied by the Lender pursuant to the terms hereof, together with appropriate instruments of reassignment and release.

18. FURTHER INDEMNIFICATION. Without limiting the obligations of the Debtor under Section 13 above, the Debtor agrees to pay, and to save the Lender harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all excise, sales or other similar taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

19. GOVERNING LAW; TERMS. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Connecticut, except to the extent that the validity or perfection of the security interest hereunder, or remedies hereunder, in respect of any particular Collateral are mandatorily governed by the law of a jurisdiction other than the State of Connecticut. Unless otherwise defined herein or in the Letter of Credit Agreement, terms used in Article 8 and/or 9 of the Uniform Commercial Code in the State of Connecticut are used herein as therein defined.

20. NO PETITION IN BANKRUPTCY. Each of the parties to this Agreement severally and not jointly, hereby covenants and agrees that, prior to the date which is one year and one day after the payment or expiration in full of all outstanding Letters of Credit, it will not institute against, or join any other Person in instituting against, the Debtor any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings or other similar proceeding.

21. WAIVER OF JURY TRIAL. THE DEBTOR AND THE LENDER MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER FUNDAMENTAL DOCUMENTS CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING, WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF THE LENDER RELATING TO THE ADMINISTRATION OF THIS AGREEMENT OR ENFORCEMENT OF THE FUNDAMENTAL DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.

-10-

EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. EACH OBLIGOR CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR THE LENDER TO ENTER INTO THIS AGREEMENT AND THE OTHER FUNDAMENTAL DOCUMENTS. THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

22. JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a) The Debtor hereby irrevocably and unconditionally submits, for itself and its property, to the non-exclusive jurisdiction of any Connecticut State court or Federal court of the United States of America sitting in Connecticut; and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, the Letter of Credit Agreement, the other Fundamental Documents, or for recognition of enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Connecticut State or, to the extent permitted by law, in such Federal court.

(a) The Debtor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement, the Letter of Credit Agreement or the other Fundamental Documents in any Connecticut State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

-11-

provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby.

AGREEMENT FOR STANDBY LETTER OF CREDIT

For good and valuable consideration, the receipt and adequacy of which is hereby acknowl-edged, the Bank and the Customer agree as follows:

1. Each reference hereinafter contained to: (a) "Bank", "Bank's Address", "Customer", "Customer's Address", and "Expiry Date" shall be deemed to refer to the defined terms on Page 1 of this Agreement; (b) "Agreement" shall be deemed to refer to this Application and Agreement for Standby Letter of Credit, including without limitation the application portion on Page 1 hereof; (c) "Business Day" shall be deemed to refer to any day on which commercial banks located in the state of the Bank's Address are not required or authorized to remain closed and which is not a Saturday, Sunday or legal holiday; (d) "Credit" shall be deemed to refer to the letter of credit to be issued by the Bank substantially in the form set forth in the application portion of this Agreement, all amendements thereto, and any substitutions or replacements thereof; (e) "Events of Default" shall be deemed to refer to one or more of the events of default or defaults specified in Paragraph 6 of this Agreement; (f) "Prime Rate" shall be deemed to refer to the rate of interest designated by the Bank from time to time as being its prime rate of interest.

2.As to instruments payable in U.S. Dollars, the Customer will: (a) pay the Bank in U.S. Dollars the amount paid on any sight draft on demand or, at the Bank's option, pay the Bank in advance the amount required to pay such draft; and (b) pay the Bank in U.S. Dollars the amount of each acceptance on demand, but in any event not later than one Business Day prior to maturity.

3. As to instruments payable in a foreign currency, the Customer will: (a) pay the Bank in U.S. Dollars, the equivalent of the amount paid on any sight draft, immediately upon such payment being made, at the Bank's then selling rate for cable transfers to the place of payment in the currency in which the draft is drawn; and (b) in the case of each acceptance pay the Bank in U.S. Dollars, on demand, but in any event in time to reach the place of payment by mail not later than one Business Day prior to maturity, the equivalent thereof at the Bank's then selling rate for the currency in which the acceptance is payable, or at the Bank's option pay the Bank on demand the equivalent of the acceptance in U.S. Dollars at the Bank's then selling rate for cable transfers to the place of payment in such currency. If for any reason there should exist at the time in question no rate of exchange generally current in the state of the Bank's Address for effective cable transfers of the sort provided for, the Customer will pay the Bank on demand an amount in U.S. Dollars equivalent to the actual cost to the Bank of settlement of the Bank's obligations to the payor of the draft or acceptance or any holder thereof, as the case may be, however and whenever such settlement is made by the Bank.

4. The Customer will pay the Bank on demand a commission at such rate as the Bank may determine, plus interest where chargeable, and all fees, charges and expenses, including reason-able counsel fees, incurred or paid by the Bank in protecting or enforcing its rights under this Agreement, or in connection with the Credit issued pursuant hereto and any confirmation thereof, or arising or caused in any manner whatsoever in connection therewith, including without limitation reasonable counsel fees and expenses incurred in connection with the defense of all actions seeking to restrain or enjoin payment of the Credit or any draft accepted under the Credit or attachment or garnishment proceedings involving any of the proceeds of the Credit or any such draft. In addition to commissions, fees, charges, expenses and amounts otherwise payable with respect to the issuance of the Credit, the Customer shall pay to the Bank on demand such amounts as the Bank in its sole discretion determines are necessary to compensate the Bank for any costs attributable to the Bank's issuing or having outstanding or making payment under the Credit resulting from the application of any domestic or foreign law or regulation or the interpretation or administration thereof applicable to the Bank regarding any reserve, assessment, capitalization (including the cost of maintaining capital sufficient to permit issuance of the Credit, provided the cost attributed to the Credit is determined in good faith by any reasonable method) or similar requirement whether existing at the time of issuance of the Credit or adopted thereafter. All amounts not paid when due in accordance with this Agreement (including without limitation those set forth in paragraph 2, 3 and 4 hereof) shall bear interest until paid in full at a rate per annum equal to six percent (6%) above the Prime Rate, not to exceed the maximum rate of interest permitted by applicable law. Each change in such interest rate shall take effect simultaneously with the corresponding change in the Prime Rate. The Bank is hereby irrevocably authorized to charge any one or more of the Customer's accounts with the Bank for payment in full or in part of any of the Customer's obligations to the Bank under this Agreement. At the option of the Bank, if there is a separate revolving line of credit, line of credit, or other credit facility existing between the Bank and the Customer, the Bank is irrevocably authorized to satisfy the Customer's reimbursement obligation to the Bank, in whole or in part, by making an advance under such facility.

5. The users of the Credit shall be deemed the Customer's agents, and the Customer assumes all risks of their acts or omissions. The Customer's obligation to pay the Bank for all amounts due under this Agreement is absolute and unconditional. Such obligation of the Customer shall not be affected by, and the Bank shall not be responsible for, the validity, sufficiency, correctness or genuineness of documents, even if such documents should in fact prove to be in any or all respects incorrect, defective, invalid, insufficient, fradulent or forged; any breach of contract or disputes between any beneificiary of the Credit and the Customer; the existence of any claim, setoff, defense or other right which the Customer may have at any time against the beneficiary or any other person or entity, whether in connection with this Agreement, the transaction contemplated herein or any unrelated transaction; the failure of any draft or certificate to bear reference or adequate reference to the Credit; errors, omissions, interruptions or delays in transmission or delivery of any messages by mail, telex, telecopy, or otherwise; the exchange, release or non-perfection of any collateral or the release of any guarantor; or any consequences arising from causes beyond the Bank's control; and none of the above shall affect, impair or prevent the fixing of any of the Bank's rights or powers hereunder. Any provision with respect to any of the foregoing matters which is contained in the Credit itself may be waived by the Bank. The Customer will hold the Bank harmless from all loss or damage in respect of any of the foregoing matters, and from any and all damage and loss whatsoever suffered by the Bank by reason of any and all action taken by the Bank in good faith.

6. The Customer will deliver to the Bank on demand such additional security (including cash) as the Bank may from time to time require, to be held as general collateral for all the Customer's liabilities to the Bank hereunder and for all other liabilities, absolute or contingent due or to become due, which may be at any time owing to Bank by the Customer. All property belonging to the Customer, including any collection items, now or hereafter handed to the Bank or for any purpose left in the Bank's possession by the Customer or for the Customer's account, or in transit to or from the Bank, by mail or carriers, and all balances of any deposit accounts the Customer may have with the Bank, are hereby made security, and the Bank is hereby granted a security interest therein, for all such liabilities and may be held or disposed of as the Bank may see fit, and applied toward any payment of any and all such liabilities, all of which shall become immediately due and payable upon an Event of Default. Each of the following events or actions by or affecting the Customer shall constitute an Event of Default; default in the performance of any undertaking to the Bank under this Agreement, any trust receipt, or under any other obligation to the Bank or agreement with the Bank; insolvency, or the filing by or against the Customer of any petition under the Bankruptcy Code or any similar Federal or state statute; the filing by or against the Customer of a petition for the appointment of a receiver; the making of an assignment for the benefit of creditors; the Customer's death, failure in business, dissolution, suspension or termination of existence; any seizure, vesting or intervention by or under authority of a government, by which the Customer's management is displaced or its authority in the conduct of its business is curtailed; or the attachment or distraint of any of the Customer's funds or other property which may be in, or come into, the Bank's possession or under the Bank's control, or that of any third party acting for the Bank, or of the same becoming subject at any time to any mandatory order of court or other legal process. The Bank may at any time transfer into the Bank's or its nominee's name all or any part of such security, before or after maturity of any of the Customer's obligations and without any notice to the Customer or any other person. Whenever the Bank deems it necessary for the Bank's or the Customer's protection, or after an Event of Default specified herein, or other default, the Bank shall have the right to accelerate and make immediately due and payable all of the Customer's obligations to the Bank under the Credit and this Agreement and under any other document or agreement (including without limitation the obligations evidenced by the outstanding (but undrawn upon) Credit and/or by accpetances which have not matured). The Bank shall have, in addition to all other rights and remedies under applicable law, the rights and remedies of a secured party under the Uniform Commercial Code, and the Bank may, without regard to such maturity, realize upon (by sale, assignment, setoff, application or otherwise) all or any part of such security, in each case without advertisement, notice to, tender, deamnd or call of any kind upon the Customer or any other person, except that, unless such security is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Bank shall give the Customer three Business Days' prior written notice of the time and place of any public sale thereof or of the time after which any private sale or other intended disposition thereof is to be made. Any such sale or assignment may be public, private or upon any broker's board or exchange, for cash, on credit or for future delivery, and at such price and upon such terms and conditions, as the Bank deems appropriate. For this purpose, the Bank may, so far as the Customer can give authority therefor, enter upon any premises on which such security or any proceeds thereof may be situated and remove the same therefrom, or require that such security or proceeds be made available to the bank at a place or places reasonably convenient to both the Bank and the Customer. The Bank may acquire all or any part of such security and any purchaser shall hold same free from any equity of redemption or other claim or right on the Customer's part, which are hereby specifically waived and released. The Bank may discount, settle, comprise, or extend any obligations constituting such security, and sue thereon in the Bank's or the Customer's name. However, the Bank shall not be liable for failure to collect or demand payment of, or protest or give notice of non-payment of, any obligation included in such security or part thereof, or for any delay in so doing, nor shall the Bank be under any obligation to take any action whatever in respect to such security or any part thereof. No advertising, notice, tender, demand, or call at any time given or made shall be a waiver of the Bank's right to proceed in the same or other instances without any further action.

7. The receipt by the Bank at any time of other collateral shall not be deemed a waiver of any of the Bank's rights or powers relating to any collateral which the Bank may hold at the time of such receipt.

8. No failure on the part of the Bank to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other further exercise thereof or the exercise of any right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. No amendment or waiver of any provision of this Agreement nor consent to any departure by the parties hereto shall in any event be effective unless the same shall be in writing and signed by such party, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

9. This Agreement shall continue in force notwithstanding any change in the composition of firm or firms parties hereto, or drawers of drafts hereunder, or in the incorporation of any such firm.
