PART I

ITEM 1. BUSINESS

IN THIS DOCUMENT, "WE," "US," "OUR" AND THE "COMPANY" REFER TO ARCH CAPITAL GROUP LTD. OR ITS PREDECESSOR, ARCH CAPITAL GROUP (U.S.) INC., AND/OR THEIR SUBSIDIARIES, AS THE CONTEXT REQUIRES. WE REFER YOU TO THE SECTION BELOW ENTITLED "RISK FACTORS" FOR A DISCUSSION OF CERTAIN RISKS RELATING TO OUR BUSINESS.

GENERAL

STRATEGY

Arch Capital Group Ltd. ("ACGL") is a Bermuda-based, diversified financial services holding company, with an emphasis on the insurance sector. We own and intend to acquire operating businesses that will enable us to generate both fee-based revenue (E.G., commissions and advisory and management fees) and risk-based revenue (I.E., insurance premium). We will participate in the insurance sector through our ownership interest in various insurance-related entities such as intermediaries, underwriting agencies, service providers and insurance companies, each of which will capture a portion of insurance premium at different points in the insurance chain. As part of our strategy of diversification and of growing our sources of fee-based revenues, we may also acquire ownership interests in financial services entities outside the insurance sector.

In connection with the development of the risk bearing portion of our business, we intend to capitalize a Bermuda-based reinsurance company, which will underwrite business produced by intermediaries, underwriting agencies and insurance companies owned by or affiliated with us, as well as business produced by third parties. The Bermuda location provides us with a favorable business environment for engaging in some of our risk-based activities. We believe that our ownership interests in a Bermuda-based reinsurance company and other risk-bearing entities, as well as in insurance intermediaries, underwriting agencies and other fee-based businesses, will enable us to maximize risk-based revenues during periods in the underwriting cycle when it is favorable to assume more underwriting risk, and to increase our focus on fee-based revenues and assume less underwriting risk when the underwriting cycle presents less favorable conditions.

Since the sale of our reinsurance business on May 5, 2000 to Folksamerica Reinsurance Company, we made two acquisitions and have announced a third acquisition in furtherance of our strategy. On December 4, 2000, we acquired Hales & Company, a merchant banking firm specializing in the insurance industry. In addition to providing us with a growing franchise in the insurance services sector, the employees of Hales assist us in finding acquisition candidates, evaluating them, conducting due diligence and monitoring acquired businesses.

On February 28, 2001, we acquired one of our investee companies, American Independent Insurance Company. American Independent underwrites private passenger automobile liability and physical damage insurance primarily in the Commonwealth of Pennsylvania. On an ongoing basis we will determine the amount of the insurance premium underwritten by American Independent that will be retained by us and the amount of commission income we will capture through the purchase of reinsurance.

On March 23, 2001, we announced our agreement to acquire Altus Holdings, Ltd., which provides insurance and alternative risk transfer services through rent-a-captive and other facilities. The Altus group includes First American Insurance Company, an admitted insurer in 49 states with an A.M. Best rating of "A-." Upon completion of the acquisition of Altus, we believe we will be in a position to provide a range of services within and to the insurance sector. Through our merchant bank, Hales, we can provide advisory services to insurance entities seeking a buyer, acquisition candidate or capital, whether from third parties or from Distribution Partners Investment Capital, L.P., a private equity fund investing in insurance distribution entities which is affiliated with the company and Hales. If any such entity controls a sufficient amount of attractive premium or is consistently profitable, it could be a candidate for acquisition by us or to receive financing from us. Through Altus and First American, we can assist a producer, manager or distributor of insurance premium

1

seeking to participate in the underwriting results of its business or requiring a policy issuing carrier. Altus can also provide services to businesses that are seeking to insure a portion of their corporate risk exposures with a captive insurance company.

HISTORY

ACGL is a Bermuda company formed in September 2000. In November 2000, ACGL became the sole shareholder of Arch Capital Group (U.S.) Inc. ("Arch-U.S.") pursuant to the internal reorganization transaction described below. Arch-U.S. is a Delaware company formed in March 1995 under the original name of "Risk Capital Holdings." Arch-U.S. commenced operations in September 1995 following the completion of its initial public offering. Prior to May 5, 2000, Arch-U.S. provided reinsurance and other forms of capital for insurance companies through its wholly owned subsidiary, Arch Reinsurance Company ("Arch Re"), a Nebraska corporation formed in 1995 under the original name of "Risk Capital Reinsurance Company." On May 5, 2000, Arch-U.S. sold the reinsurance operations of Arch Re to Folksamerica Reinsurance Company in the asset sale described below. Following the asset sale, we have made two acquisitions and have announced a third acquisition in furtherance of our strategy.

REORGANIZATION

On November 8, 2000, following the approval of Arch-U.S.'s shareholders, Arch-U.S. completed an internal reorganization that resulted in Arch-U.S. becoming a wholly owned subsidiary of ACGL. The establishment of a Bermuda holding company for Arch-U.S. should allow us to benefit from a favorable business environment. ACGL performs the holding company functions previously conducted by Arch-U.S., and the shareholders of Arch-U.S. have become the shareholders of ACGL. Prior to the reorganization, ACGL had no significant assets or capitalization and had not engaged in any business or prior activities other than in connection with the reorganization. Arch-U.S. remains the holding company for certain of our U.S. subsidiaries.

COMPANY INFORMATION

At December 31, 2000, our consolidated shareholders' equity was $275.3 million. Our common shares are traded on the Nasdaq National Market under the symbol "ACGL." Our principal offices are located at Clarendon House, 2 Church Street, Hamilton HM 11 Bermuda (phone number: (441) 295-1422), and our executive offices are located at 20 Horseneck Lane, Greenwich, Connecticut 06830 (phone number: (203) 862-4300).

SIGNIFICANT 2000 DEVELOPMENTS

XL SHARE REPURCHASE

On March 2, 2000, we repurchased from XL Capital, then our single largest shareholder, all of the 4,755,000 common shares held by it for a purchase price of $12.45 per share, or a total of $59.2 million. The per share repurchase price was determined as the lesser of (1) 85% of the average closing market price for the common shares during the 20 trading days beginning January 21, 2000, which was $12.45, and (2) $15. We paid XL the consideration for the repurchase with certain of our privately held investments. XL paid us in cash the $3.6 million difference between the repurchase price and the value of such investments. See note 13 of the notes accompanying our consolidated financial statements.

SALE OF REINSURANCE OPERATIONS

On May 5, 2000, we sold the reinsurance operations of Arch Re pursuant to an agreement entered into as of January 10, 2000 with Folksamerica Reinsurance Company and Folksamerica Holding Company. The sale was precipitated by, among other things, losses on Arch Re's reinsurance business and increasing competition, which had been adversely affecting Arch Re's results of operations and financial condition. Folksamerica Reinsurance Company assumed Arch Re's liabilities under the reinsurance agreements transferred in the asset sale and Arch Re transferred to Folksamerica Reinsurance Company assets estimated in an aggregate amount

2

equal in book value to the book value of the liabilities assumed. In consideration for the transfer of Arch Re's book of business, Folksamerica paid $20.084 million (net of a credit equal to $251,000 granted to Folksamerica for certain tax costs) in cash at the closing, subject to post-closing adjustments based on an independent actuarial report of the claim liabilities transferred and an independent audit of the net assets sold. Following the completion of such report and audit, the parties agreed upon net post-closing adjustments in the amount of approximately $3.2 million payable by us, which consisted of a $4.2 million reduction in the purchase price less $1 million in net book value of the assets and liabilities actually transferred at closing.

Under the terms of the agreement, we placed $20 million of the purchase price in escrow for a period of five years. Such amounts represent restricted funds that appear under a separate caption entitled "Securities held in escrow" on our consolidated balance sheet at December 31, 2000. These funds will 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 by a certain managing underwriting agency are deficient as measured at the end of such five-year period or to satisfy certain indemnity claims Folksamerica may have during such period. In connection with the escrow arrangement, we will record a loss in an amount equal to any probable deficiency in the related reserve that may become known during or at the end of the five-year period. If such loss reserves are redundant, all of the escrowed funds will be released from escrow to us and Folksamerica will pay us an amount equal to such redundancy. The agreement also provided that an additional amount of up to $5 million would be placed in escrow for a period of five years to the extent that Arch Re's reserves at closing on all business other than that covered by the $20 million escrow were less by at least a specified amount than those estimated by its independent actuaries. No such supplemental escrow was required.

As required under the agreement, Folksamerica reported to us that adverse development had occurred in the loss reserves subject to the Folksamerica escrow agreement for the period from May 5, 2000 to December 31, 2000. Based on such information and an independent actuarial analysis, we recorded in the 2000 fourth quarter a loss contingency of $15 million, on a pre-tax basis, to recognize a probable deficiency in such reserves. The actuarial analysis was based on estimates of claims and claims expenses incurred as of December 31, 2000 and, therefore, the amount ultimately paid may be more or less than such estimate.

Under the terms of the agreement, we also purchased reinsurance protection covering our 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 we believe that any such net financial loss will not exceed $5.4 million, we have agreed to reimburse Folksamerica for a net financial loss it may incur that is in excess of $5.4 million for aviation losses under certain circumstances prior to May 5, 2003.

We also made representations and warranties to Folksamerica about us and the business transferred to Folksamerica for which we retain exposure for certain periods. Although Folksamerica has not asserted that any amount is currently due under any of the indemnities provided by us 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, we deny the validity of any such potential claim.

Comprehensive income and net book value gain                   $ 3,384
                                                             ============

(1) The income tax benefit of $1.5 million relating to post-closing adjustments of $4.2 million was offset by an equivalent deferred tax asset valuation allowance. The income tax benefit of $1.9 million relating to the realized loss for securities transferred at market value was offset by an equivalent deferred tax asset valuation allowance.

At the closing of the asset sale, Arch Re and Folksamerica entered into a transfer and assumption agreement, under which Folksamerica assumed Arch Re's rights and obligations under the reinsurance agreements transferred in the asset sale. The reinsureds under such agreements that were in-force were notified that Folksamerica had assumed Arch Re's obligations and that, unless the reinsureds object to the assumption, Arch Re will be released from its obligations to those reinsureds. None of such reinsureds objected to the assumption and, accordingly, the gross liabilities for such business have been removed from the accounts of Arch Re for statutory and GAAP accounting purposes. However, Arch Re 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 us 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 us, Arch Re may incur losses relating to the reinsurance agreements transferred in the asset sale.

See note 2 of the notes accompanying our consolidated financial statements.

ACQUISITIONS

Since the asset sale, we have sought to identify and evaluate potential acquisition candidates in furtherance of our strategy of building a diversified financial services holding company (see "General--Strategy"). We utilize our large network of contacts in the insurance and financial services industries to search for transaction opportunities. These contacts include present and former business partners, traditional financing sources (including investment banking firms, venture capital firms and other banking and financing sources), and insurance and reinsurance intermediaries. Since the asset sale, we have completed our acquisitions of Hales and American Independent and have entered into a definitive agreement to acquire Altus, as described below. In addition to providing us with a growing franchise in the insurance services sector, the employees of Hales assist

4

us in finding acquisition candidates, evaluating them, conducting due diligence and monitoring acquired businesses.

HALES & COMPANY

On December 4, 2000, we acquired substantially all of the assets of Hales Capital Advisors, LLC, a privately held merchant banking firm specializing in the insurance industry. Founded in 1973, Hales is a merger and acquisition advisor to middle-market insurance organizations and the manager of the general partner of Distribution Partners Investment Capital, L.P., a private equity fund with $51 million of committed capital. Distribution Partners focuses on equity investments in insurance distribution and distribution-related service companies.

The purchase price for the Hales assets consisted of 300,000 of our common shares (which shares are subject to a two-year lock-up) and $1.9 million in cash, representing a total purchase price of approximately $6.4 million (based on the closing market price of our common shares on December 4, 2000). Substantially all of this amount is reflected as goodwill and is being amortized over a period not to exceed 15 years. As part of the acquisition, we made a commitment of $1.2 million to the general partner of Distribution Partners.

The Hales business is conducted through our newly-formed subsidiary, Hales & Company Inc. Hales provides merger and acquisition advisory, valuation and capital raising services to its clients. Hales' clients include insurance distributors, insurance companies, banks and other financial institutions with interests in insurance distribution.

AMERICAN INDEPENDENT INSURANCE HOLDING COMPANY

On February 28, 2001, we completed a reorganization transaction pursuant to which we acquired all of the common stock of American Independent Insurance Holding Company ("AIHC"), one of our investee companies. See note 4 and note 15 of the notes accompanying our consolidated financial statements. AIHC, through its wholly owned subsidiary, American Independent Insurance Company, underwrites private passenger automobile liability and physical damage insurance primarily in Pennsylvania.

We purchased a portion of the outstanding shares of AIHC for $1.25 million. The remaining outstanding shares of AIHC were redeemed by AIHC in exchange for the right to receive a portion of the proceeds resulting from the final adjudication or settlement of certain lawsuits that AIHC, as plaintiff, has previously filed against certain defendants. A third party also forgave the obligations owing to it under certain notes previously issued by AIHC in the aggregate principal amount of $4 million and returned certain warrants to purchase shares of AIHC in exchange for the right to receive a portion of the proceeds resulting from the final adjudication or settlement of such lawsuits. Immediately after our purchase of AIHC, we contributed to the capital of AIHC notes in the aggregate principal amount of $8.5 million that were issued to us in connection with loans we had previously made to AIHC and also returned certain warrants to purchase shares of AIHC. Following our purchase, we also made a capital contribution to AIHC in the amount of $11.0 million.

In connection with the loans we had previously made to AIHC, we had obtained rights to provide reinsurance to American Independent for specified periods, which rights had been transferred to Folksamerica in the asset sale on May 5, 2000. In connection with our acquisition of AIHC, Folksamerica released American Independent from these reinsurance commitments at a cost to American Independent of $1.5 million.

American Independent, which has an A.M. Best rating of C++, focuses on non-standard automobile insurance providing liability and physical damage coverage to insureds. American Independent operates and writes insurance in Pennsylvania, Delaware and Maryland and generates its business through a network of independent agents, who are compensated for their services by payment of commissions on the premiums they generate. American Independent reinsures a substantial portion of its business with reinsurers. These reinsurance arrangements do not relieve American Independent from its obligations to policyholders.

ALTUS HOLDINGS, LTD.

On March 23, 2001, we entered into a reorganization agreement for the acquisition of all of the remaining ownership interests in Altus Holdings, Ltd., one of our current investee companies. Altus, a privately held company, provides insurance and alternative risk transfer services through rent-a-captive and other facilities. The Altus group includes First American Insurance Company, an admitted insurer with licenses in 49 states and an A.M. Best rating of A-. See note 4 and note 15 of the notes accompanying our consolidated financial statements.

Under the agreement, we will acquire the remaining ownership interests in Altus for a purchase price of approximately $36 million. The transaction is contingent on obtaining applicable regulatory approvals, expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, and other customary closing conditions.

INVESTMENTS

Prior to the sale of our reinsurance operations on May 5, 2000, our investment goals had been to support Arch Re's reinsurance activities. Following the asset sale, we have sought to acquire operating companies in support of our business plan of building a diversified financial services holding company.

OPERATIONS

At December 31, 2000, cash and invested assets totaled approximately $279.1 million, consisting of $108.9 million of cash and short-term investments, $38.5 million of publicly traded fixed maturity investments, $21.0 million of securities held in escrow under the terms of the Folksamerica transaction, $51.3 million of publicly traded equity securities, and $59.4 million of privately held securities.

A significant portion of our investment portfolio is currently comprised of equity securities issued by insurance and reinsurance companies and companies providing services to the insurance industry. The portfolio lacks industry diversification and is particularly subject to the performance of the insurance industry. Such performance will affect the market prices of a significant portion of our investment portfolio and the income and return on such investments.

Fixed income investments are used to provide shorter-term liquidity and current returns. The fixed income securities portfolio generally is invested in high quality, liquid securities, including securities issued by U.S. government agencies and U.S. government guaranteed securities.

We allocated in early 1998 approximately $35 million for investment in a diversified portfolio of high yielding below investment grade fixed maturity investments managed by Miller Anderson & Sherrerd, LLP, a subsidiary of Morgan Stanley & Co. Such amount was taken from funds that were previously allocated for investing in short-term securities. Miller Anderson manages the portfolio subject to investment guidelines established by our board of directors. At December 31, 2000, our investments did not include any high yield securities due to the restructuring of our investment portfolio in connection with our reorganization on November 8, 2000. However, at March 15, 2001, our high yield portfolio included approximately $33 million of such securities.

The components of net investment income for the years ended December 31, 2000, 1999 and 1998 are summarized in a table found in note 4 under the caption "Investment Information" of the notes accompanying our consolidated financial statements.

Our current investment guidelines restrict the portion of our fixed high yield maturities portfolio that can be held in lower quality securities. At December 31, 2000, 100% of the fixed maturity and short-term investments were rated investment grade by Moody's Investors Service, Inc. or Standard & Poor's Corporation and had an average quality rating of AA and an average duration of approximately 1.3 years.

Contractual maturities of our consolidated fixed maturity securities are shown below. Expected maturities, which are our best estimates, will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment premiums or penalties.

equity investments were in securities issued by insurance and reinsurance companies or companies providing services to the insurance industry.

Please refer to note 4 under the caption "Investment Information" of the notes accompanying our consolidated financial statements for information regarding our publicly traded and privately held securities and their carrying values, and commitments made by us relating to our privately held securities.

We have not invested in derivative financial instruments such as futures, forward contracts, swaps, or options or other financial instruments with similar characteristics such as interest rate caps or floors and fixed-rate loan commitments. Our portfolio includes market sensitive instruments, such as mortgage-backed securities, which are subject to prepayment risk and changes in market value in connection with changes in interest rates. Our investments in mortgage-backed securities are classified as available for sale and are not held for trading purposes. These investments amounted to approximately $5.5 million, or 2% of cash and invested assets at December 31, 2000, $27.3 million, or 4.7% of cash and invested assets at December 31, 1999, and $33.5 million, or 6% of cash and invested assets at December 31, 1998.

For additional information on our divested reinsurance business, please refer to "Management's Discussion and Analysis of Financial Condition and Results of Operations--Results of Operations" and note 7 (claims and claims expenses), note
8 (retrocession agreements), and note 12 (business information) of the notes accompanying our consolidated financial statements.

Prior to the asset sale, Arch Re, as a reinsurer, was required to establish and maintain reserves to cover its estimated ultimate liability for unpaid claims and claims expenses with respect to reported and unreported claims incurred as of the end of each accounting period (net of estimated related salvage and subrogation claims and retrocession recoverables (if any) of Arch Re). These reserves are estimates involving actuarial and statistical projections at a given time of what Arch Re expects the ultimate settlement and administration of claims to cost based on facts and circumstances then known, predictions of future events, estimates of future trends in claims severity and other variable factors such as inflation and new concepts of liability. For certain types of claims, it may over time be necessary to revise estimated potential loss exposure and therefore Arch Re's unpaid claims and claims expense reserves. The inherent uncertainties of estimating claims and claims expense reserves are exacerbated for reinsurers by the significant periods of time (the "tail") that often elapse between the occurrence of an insured claim, the reporting of the claim to the primary insurer and ultimately to the reinsurer, and the primary insurer's payment of that claim and subsequent indemnification by the reinsurer. As a consequence, actual claims and claims expenses paid may deviate, perhaps substantially, from estimates reflected in Arch Re's reserves in its financial statements. Please refer to note 7 of the notes accompanying our consolidated financial statements for a reconciliation of claims and claims

8

expense reserves for the period from January 1, 2000 to December 31, 2000 and the years ended December 31, 1999 and 1998.

The following table represents the development of generally accepted accounting principles ("GAAP") balance sheet reserves for 1996 through December 31, 2000. The top line of the table shows the reserves, net of reinsurance recoverables, at the balance sheet date for each of the indicated years. This represents the estimated amounts of net claims and claims expenses arising in all prior years that are unpaid at the balance sheet date, including incurred but not reported ("IBNR") reserves. The table also shows the reestimated amount of the previously recorded reserve based on experience as of the end of each succeeding year. The estimate changes as more information becomes known about the frequency and severity of claims for individual years. The "cumulative redundancy (deficiency)" represents the aggregate change in the estimates over all prior years. The table also shows the cumulative amounts paid as of successive years with respect to that reserve liability. The lower portion of the table represents the claim development of the gross balance sheet reserves for 1996 through December 31, 2000.

With respect to the information in the table below, it should be noted that each amount includes the effects of all changes in amounts for prior periods. This table does not present accident or policy year development data. For additional information on Arch Re's reserving and retrocessional activities prior to the asset sale, please refer to notes 7 and 8 of the notes accompanying our consolidated financial statements.

COMPETITION

Following the sale of our reinsurance operations on May 5, 2000, we have sought to acquire operating companies in support of our business plan of building a diversified financial services holding company. We are a small participant in the market of seeking mergers with and acquisitions of all or a portion of other entities. We encounter intense competition from other entities having business objectives similar to ours. Many of these entities are well-established and have extensive experience in identifying and effecting business combinations directly or through affiliates. Many of these competitors possess greater financial, technical, human and other resources than ours and we cannot assure you that we will have the ability to compete successfully. Our financial resources are limited in comparison to those of many of our competitors. We cannot assure you that we will be able to achieve our stated business objectives.

HALES. Hales encounters significant competition in all aspects of its business from other merchant and investment banking firms. Many of Hales' competitors have greater capital, financial and other resources than Hales and offer access to markets and products and services that Hales does not offer. The principal

10

competitive factors influencing Hales' business are its professional staff, its reputation in the marketplace, its existing client relationships, and the ability to commit capital to client transactions through ACGL or Distribution Partners, a fund which is affiliated with ACGL and Hales.

AMERICAN INDEPENDENT. The property and casualty insurance industry is highly competitive. Competition is based on many factors, including price, customer service, consumer recognition, coverages offered, claims handling, financial stability, and geographic coverage. There are numerous companies competing for business in the markets in which American Independent operates, many of which are substantially larger and have considerably greater financial resources than American Independent. In addition, since the insurance products of American Independent are marketed exclusively through independent agents, most of which represent more than one insurer, American Independent faces competition within each agency.

REGULATORY CONSIDERATIONS

In common with other insurers, American Independent and Arch Re are subject to comprehensive regulation and supervision in the jurisdictions where they are domiciled and licensed to conduct business. At the date of this report, American Independent is licensed as an insurer in Delaware, Maryland and Pennsylvania, and Arch Re maintains insurance licenses or reinsurance accreditations or other approvals as a reinsurer in 44 states and is recognized as an admitted reinsurer for surety business by the U.S. Treasury Department. The reinsurance operations of Arch Re were sold on May 5, 2000. See note 2 of the notes accompanying our consolidated financial statements and "Business--Significant 2000 Developments--Sale of Reinsurance Operations."

The laws and regulations of the state of domicile have the most significant impact on operations. This regulation and supervision is designed to protect policyholders rather than investors. Generally, regulatory authorities have broad supervisory powers over such matters as licenses, standards of solvency, premium rates, policy forms, investments, security deposits, methods of accounting, form and content of financial statements, reserves and provisions for unearned premiums, unpaid losses and loss adjustment expenses, reinsurance, minimum capital and surplus requirements, dividends and other distributions to shareholders, periodic examinations and annual and other report filings. Most states have, and continue to implement, laws which establish standards for current, as well as continued, state accreditation. Certain insurance regulatory requirements are highlighted below.

STATE EXAMINATIONS

Insurance departments conduct periodic examinations of the affairs of insurance companies and require the filing of annual and other reports relating to the financial condition of companies and other matters. The Pennsylvania Insurance Department completed a financial examination of American Independent's records, accounts and business affairs for the four-year period ended December 31, 1996 and reported no material findings in connection with the examination. The Nebraska Insurance Department completed a financial examination of Arch Re's records, accounts and business affairs for the period October 1995 through December 31, 1997 and reported no material findings in connection with the examination.

HOLDING COMPANY ACTS

State insurance holding company statutes provide a regulatory apparatus which is designed to protect the financial condition of domestic insurers operating within a holding company system. All holding company statutes require disclosure and, in some instances, prior approval by the state of domicile of significant transactions between the domestic insurer and an affiliate. Such transactions typically include sales, purchases, exchanges, loans and extensions of credit, and investments between an insurance company and its affiliates, involving in the aggregate certain percentages of the insurance company's admitted assets or policyholders surplus, or dividends that exceed certain percentages of the company's surplus or income.

Typically, the holding company statutes also require each of the insurance subsidiaries periodically to file information with state insurance regulatory authorities, including information concerning capital structure, ownership, financial condition and general business operations. Under the terms of applicable state statutes, any person or entity desiring to acquire control of a domestic insurer is required first to obtain approval of the applicable state insurance regulator.

11

REGULATION OF DIVIDENDS AND OTHER PAYMENTS FROM INSURANCE SUBSIDIARIES

The ability of an insurer to pay dividends or make other distributions is subject to insurance regulatory limitations of the insurance company's state of domicile. Generally, such laws limit the payment of dividends or other distributions above a specified level. Dividends or other distributions in excess of such thresholds are "extraordinary" and are subject to regulatory approval. Generally, during 2001, all dividends or other distributions from American Independent and Arch Re will be subject to regulatory approval. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" and note 11 of the notes accompanying our consolidated financial statements.

INSURANCE REGULATORY INFORMATION SYSTEM RATIOS

The National Association of Insurance Commissioners (the "NAIC") Insurance Regulatory Information System ("IRIS") was developed by a committee of state insurance regulators and is intended primarily to assist state insurance departments in executing their statutory mandates to oversee the financial condition of insurance companies operating in their respective states. IRIS identifies 12 industry ratios and specifies "usual values" for each ratio. Departure from the usual values of the ratios can lead to inquiries from individual state insurance commissioners as to certain aspects of an insurer's business. Insurers that report four or more unusual values are generally targeted for regulatory review. Arch Re's IRIS results for the year ended December 31, 2000 were not meaningful due to the sale of its reinsurance operations on May 5, 2000. For the year ended December 31, 2000 American Independent had eight unusual values for its IRIS ratios, principally relating to significant events occurring during 2000 which are not expected to be recur in 2001, although there can be no assurances that American Independent will achieve satisfactory IRIS results in the future. Three of American Independent's ratios, gross premiums to surplus, surplus aid to surplus, and change in writings, were outside the usual values due to significant premium growth during 2000, coupled with American Independent's reliance on reinsurance. Three other unusual values for American Independent's one year reserve development, two year reserve development, and the estimated current reserve deficiency ratios arose in connection with significant reserve strengthening recorded at December 31, 2000 for accident years 1996 through 2000. While there can be no assurances, American Independent believes that the reserve strengthening reduces the likelihood of future adverse loss development. American Independent's two year overall operating ratio was also outside the usual value due to the combined impact of the above factors. Additionally, American Independent's investment yield ratio was outside the usual value due to its capital structure preceding our acquisition of American Independent and the related investment arrangements.

RISK-BASED CAPITAL REQUIREMENTS

In order to enhance the regulation of insurer solvency, the NAIC has adopted risk-based capital requirements, which are designed to assess capital adequacy and to raise the level of protection that statutory surplus provides for policyholder obligations. The risk-based capital model for property and casualty insurance companies measures three major areas of risk facing property and casualty insurers: (1) underwriting, which encompasses the risk of adverse loss development and inadequate pricing; (2) declines in asset values arising from credit risk; and (3) declines in asset values arising from investment risks. Insurers having less statutory surplus than required by the risk-based capital calculation will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy. Equity investments in common stock typically are valued at 85% of their market value under the risk-based capital guidelines. For equity investments in insurance company affiliates, the risk-based capital requirement for the equity securities of any such affiliate would generally be the insurer's proportionate share of the affiliate's risk-based capital requirement. For a discussion of "affiliate" status under the insurance laws, see "--Holding Company Acts" above.

Under the approved formula, an insurer's statutory surplus is compared to its risk based capital requirement. If this ratio is above a minimum threshold, no company or regulatory action is necessary. Below this threshold are four distinct action levels at which a regulator can intervene with increasing degrees of authority over an insurer as the ratio of surplus to risk based capital requirement decreases. The four action levels include: (1) insurer is required to submit a plan for corrective action, (2) insurer is subject to examination, analysis and

12

specific corrective action, (3) regulators may place insurer under regulatory control, and (4) regulators are required to place insurer under regulatory control. At December 31, 2000, Arch Re's surplus exceeded the risk based capital threshold that would require either company or regulatory action. At such date, American Independent's surplus did not exceed the minimum threshold due to the reserve strengthening recorded at December 31, 2000, American Independent's reliance on reinsurance, and the concentration of its portfolio in few investments. As a result, American Independent is subject to examination and analysis by regulators (I.E., action level "2"). Although there can be no assurance that American Independent will not require additional capital, American Independent believes that its level of surplus compared to its risk based capital requirement should improve during 2001 due to anticipated expense ratio improvements, planned premium rate increases, the recent reserve strengthening, expected premium growth, and the planned restructuring of its investment portfolio.

GUARANTY FUNDS AND ASSIGNED RISK PLANS

Most states require all admitted insurance companies to participate in their respective guaranty funds, which cover certain claims against insolvent insurers. Solvent insurers licensed in these states are required to cover the losses paid on behalf of insolvent insurers by the guaranty funds and are generally subject to annual assessments in the state by its guaranty fund to cover these losses. Some states also require licensed insurance companies to participate in assigned risk plans which provide coverage for automobile insurance and other lines for insureds which, for various reasons, cannot otherwise obtain insurance in the open market. This participation may take the form of reinsuring a portion of a pool of policies or the direct issuance of policies to insureds. The calculation of an insurer's participation in these plans is usually based on the amount of premium for that type of coverage that was written by the insurer on a voluntary basis in a prior year. Assigned risk pools tend to produce losses which result in assessments to insurers writing the same lines on a voluntary basis.

FEDERAL REGULATION

Although state regulation is the dominant form of regulation for insurance and reinsurance business, the federal government has shown increasing concern over the adequacy of state regulation. It is not possible to predict the future impact of any potential federal regulations or other possible laws or regulations on our insurance subsidiaries' capital and operations, and such laws or regulations could materially adversely affect their business.

LEGISLATIVE AND REGULATORY PROPOSALS

From time to time various regulatory and legislative changes have been proposed in the insurance and reinsurance industry. Among the proposals that have in the past been or are at present being considered are the possible introduction of federal regulation in addition to, or in lieu of, the current system of state regulation of insurers. In addition, there are a variety of proposals being considered by various state legislatures (some of which proposals have been enacted in certain states). We are unable to predict whether any of these laws and regulations will be adopted, the form in which any such laws and regulations would be adopted, or the effect, if any, these developments would have on our operations and financial condition.

RISK FACTORS

You should carefully consider the following risk factors regarding us and our business. The following review of important factors should not be construed as exhaustive and should be read in conjunction with other information that is included in this report, including, without limitation, the section entitled "Cautionary Note Regarding Forward-Looking Statements," or elsewhere.

14

WE ARE SUBJECT TO CHANGES IN BERMUDA LAW OR POLITICAL CIRCUMSTANCES.

Under current Bermuda law, we are not subject to tax on income or capital gains. Furthermore, we have obtained from the Minister of Finance of Bermuda under the Exempted Undertakings Tax Protection Act, 1966, an undertaking that, in the event that Bermuda enacts legislation imposing tax computed on profits, income, any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of the tax will not be applicable to us or our operations until March 28, 2016. We could be subject to taxes in Bermuda after that date. 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.

Bermuda's political structure is based upon a parliamentary system with two major parties, the United Bermuda Party and the Progressive Labour Party. In the most recent election, the Progressive Labour Party gained control of the legislative branch for the first time over the incumbent United Bermuda Party. To date, the government's financial and regulatory policies have not been changed in ways that we believe would materially affect us or our shareholders.

WE MAY BECOME SUBJECT TO U.S. CORPORATE INCOME TAXES.

ACGL and its non-U.S. subsidiaries intend to operate their business in a manner that will not cause them to be treated as engaged in a trade or business in the United States and, thus, will not be required to pay U.S. federal corporate income taxes (other than withholding taxes on certain U.S. source investment income). 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 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 adversely affected. See note 10 of the notes accompanying our consolidated financial statements. In addition, certain 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. Such legislation or similar legislation, if passed, and other changes in U.S. tax laws, regulations and interpretations thereof could adversely affect ACGL and its subsidiaries.

YOU MAY SUFFER ADVERSE TAX CONSEQUENCES IF WE ARE CLASSIFIED AS A PASSIVE
FOREIGN INVESTMENT COMPANY.

In connection with our current business plan, we intend to acquire all or a portion of one or more operating companies. If we own less than 25% of the equity of one of these investee companies, then the value of our investment in the investee company will be characterized as passive assets and the income from the investee company will be characterized as passive income for U.S. income tax purposes. If 50% or more of our total assets or 75% or more of our total gross income is characterized as passive, we will be deemed to be a passive foreign investment company ("PFIC") under the Internal Revenue Code. Conversely, under a look-through rule, our equity ownership of 25% or more of our investee companies would result in a proportionate share of the investee company's assets (as long as the investee company is involved in an active business) being treated as active assets of ours. Under an exception for start-up companies, ACGL should not be a PFIC for its first taxable year if it is not a PFIC in its second and third years.

If we were to be classified as a PFIC, then capital gains of any of our U.S. shareholders allocable to the period of time following the reorganization would be considered ordinary income for tax purposes, even if we are not deemed to be a PFIC for that entire period. In addition, a U.S. shareholder would owe interest on the tax on that gain as if it had realized the capital gain in equal annual installments over the period it held our shares. Shareholders could avoid the PFIC interest charge if they mark their shares to market each year and pay ordinary income tax on that gain. A U.S. shareholder may avoid some of the adverse tax consequences of owning shares in a PFIC by making a qualified electing fund ("QEF") election. A QEF election is revocable only with the consent of the Internal Revenue Service and has the following consequences to a shareholder:

15

o For any year in which the company is not a PFIC, no income tax consequences would result.

o For any year in which the company is a PFIC, the shareholder would include in its taxable income a proportionate share of the company's net ordinary income and net capital gains.

Neither the QEF election nor the mark-to-market election is permitted with respect to warrants or options held by U.S. holders, but they may be able to mitigate the adverse tax consequences of PFIC status by means of a "purge" election.

Our current intention is to ensure that more than 50% of our investments are in operating companies in which we own an equity interest of 25% or more and to take such other steps as are necessary so as not to be classified as a PFIC. While we believe that we will take adequate measures to avoid being characterized as a PFIC, we cannot assure you that we will be successful in doing so. In addition, we may incur significant costs to avoid being characterized as a PFIC, including through the disposition of securities in investee companies at depressed prices or at otherwise unfavorable times.

See note 10 of the notes accompanying our consolidated financial statements.

WE MAY INCUR SIGNIFICANT COSTS TO AVOID INVESTMENT COMPANY STATUS AND MAY SUFFER OTHER MATERIAL ADVERSE CONSEQUENCES IF DEEMED TO BE AN INVESTMENT COMPANY.

We may incur significant costs to avoid investment company status and may suffer other material adverse consequences if deemed to be an investment company under the Investment Company Act of 1940. Some equity investments in other businesses made by us to date and in the future constitute or may constitute investment securities under the Investment Company Act. A company may be deemed to be an investment company if it owns investment securities with a value exceeding 40% of its total assets, subject to certain exclusions. Investment companies are subject to registration under, and compliance with, the Investment Company Act unless an exclusion applies. However, there is no provision (except by special SEC order) for a non-U.S. company to register as an investment company under the Investment Company Act. If we were deemed to be an investment company and could not rely on an exclusion, we would be prohibited from engaging in business or issuing securities in the United States and might be subject to civil and criminal penalties for noncompliance. In addition, in such case, certain of our contracts might be voidable, and a court-appointed receiver could take control of us and liquidate our business.

Our investment securities currently comprise more than 40% of our assets. Since the sale of our reinsurance operations to Folksamerica Reinsurance Company, we have relied on a one-year exclusion from regulation under the Investment Company Act for transient investment companies. We have filed an application with the SEC requesting an order exempting us from substantially all provisions of the Investment Company Act until May 5, 2003 or until we clearly meet one of the exclusions under the Investment Company Act. We cannot assure you that the SEC will grant our request or that, if granted, the order will not be subject to conditions that will impede our ability to execute our business strategy. If the exemption order is not granted and we could not otherwise rely on an exclusion, we would attempt to reduce our investment securities as a percentage of our total assets. This reduction can be attempted in a number of ways, including the disposition of investment securities and the acquisition of assets that do not constitute investment securities. These sales may be at depressed prices and we may never realize the anticipated benefits from, or may incur losses on, these investments. We may not be able to sell some investments because of contractual or legal restrictions or our inability to locate a buyer. Moreover, we may incur tax liabilities when we sell assets. We may also be unable to purchase additional investment securities that may be important to our future operating strategy. We may not be able to identify and acquire suitable assets that do not constitute investment securities on acceptable terms.

THE ENFORCEMENT OF CIVIL LIABILITIES AGAINST US MAY BE MORE DIFFICULT.

We are a Bermuda company and in the future some of our officers and directors may be residents of various jurisdictions outside the United States. All or a substantial portion of the assets of ACGL and of those persons

16

may be located outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon those persons or to enforce in United States courts judgments obtained against those persons. ACGL has appointed National Registered Agents, Inc., New York, New York, as its agent for service of process with respect to actions based on offers and sales of securities made in the United States.

ACGL has been advised by its Bermuda counsel, Conyers Dill & Pearman, that the United States and Bermuda do not currently have a treaty providing for reciprocal recognition and enforcement of judgments of U.S. courts in civil and commercial matters and that a final judgment for the payment of money rendered by a court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would, therefore, not be automatically enforceable in Bermuda. ACGL also has been advised by Conyers Dill & Pearman that a final and conclusive judgment obtained in a court in the United States under which a sum of money is payable as compensatory damages (I.E., not being a sum claimed by a revenue authority for taxes or other charges of a similar nature by a governmental authority, or in respect of a fine or penalty or multiple or punitive damages) may be the subject of an action on a debt in the Supreme Court of Bermuda under the common law doctrine of obligation. Such an action should be successful upon proof that the sum of money is due and payable, and without having to prove the facts supporting the underlying judgment, as long as: (1) the court which gave the judgment had proper jurisdiction over the parties to such judgment; (2) such court did not contravene the rules of natural justice of Bermuda; (3) such judgment was not obtained by fraud; (4) the enforcement of the judgment would not be contrary to the public policy of Bermuda; (5) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of Bermuda; and (6) there is due compliance with the correct procedures under Bermuda law. A Bermuda court may impose civil liability on ACGL or its directors or officers in a suit brought in the Supreme Court of Bermuda against ACGL or such persons with respect to a violation of U.S. federal securities laws, provided that the facts surrounding such violation would constitute or give rise to a cause of action under Bermuda law.

WE AND OUR SHAREHOLDERS MAY SUFFER SUBSTANTIAL LOSS SHOULD OUR BUSINESS PLAN
PROVE UNSUCCESSFUL.

There can be no assurance that our future operations will generate cash flows or operating or net income, and our prospects must therefore be considered in light of the risks, expenses, problems and delays inherent in acquiring and/or establishing a new business. We and our shareholders may suffer a substantial loss should the new business plan prove to be unsuccessful.

Our success will depend to a large extent on the operations, financial condition and management of the companies in which we may acquire interests or with which we may merge. Further, these ventures may involve financial and operational risks. Financial risks include the possible incurrence of indebtedness by us in order to effect the acquisitions and the consequent need to service that indebtedness. Operational risks include the possibility that a venture does not ultimately provide the benefits we had originally anticipated while we continue to incur operating and other expenses. In addition, if we make a strategic investment by acquiring a minority interest in a company, we may lack elements of control over the operations and strategy of the business in which we invested. Furthermore, we may attempt to invest in highly leveraged operating companies. Investing in highly leveraged companies entails many risks, including the risks that the investee companies may be subject to restrictive operating and financing covenants which could reduce their flexibility and the increased likelihood that the investee companies may enter bankruptcy if they cannot meet their obligations when due. We cannot assure you that we will be successful in identifying new operating businesses, completing and financing business combination or venture transactions on favorable terms, or operating our new business successfully. In implementing our strategy, we will attempt to minimize the risk of unexpected liabilities and contingencies associated with our new operating businesses through planning, investigation and negotiation, but unexpected liabilities and contingencies may nevertheless accompany such transactions.

WE CANNOT SPECIFY THE EXACT NATURE OF THE BUSINESS RISKS WE MAY ENCOUNTER IN
THE FUTURE.

We cannot describe the specific risks presented by the business opportunities and businesses in which we will attempt to obtain an interest. Although we will endeavor to evaluate the risks inherent in a particular new

17

operating business, we cannot assure you that we will properly ascertain or assess all such risks. The new operating businesses may be in competition with larger, more established firms that have competitive advantages over us. Our investment in a business opportunity may be highly illiquid and could result in a total loss to us if the opportunity is unsuccessful.

WE MAY NEED TO SECURE ADDITIONAL FINANCING TO CARRY OUT OUR BUSINESS PLAN.

We may be required to raise cash to consummate a business combination, to provide funds for an additional infusion of capital into a new operating business or to fund any share repurchases we may make. The amount and nature of any borrowings by us will depend on numerous considerations, including our capital requirements, our perceived ability to meet debt service on any such borrowings and the then prevailing conditions in the financial markets, as well as general economic conditions. If we are able to raise additional funds through the incurrence of debt, and we do so, we would likely become subject to restrictive financial covenants. Additionally, to the extent that debt financing ultimately proves to be available, any borrowings may subject us to various risks and restrictions traditionally associated with indebtedness, including the risks of interest rate fluctuations and insufficiency of cash flow to service that indebtedness. If additional funds are raised through the issuance of equity securities, the percentage ownership of our then current shareholders would be diluted, our earnings and book value per share could be diluted and, if such equity securities take the form of preferred stock, the holders of such preferred stock may have rights, preferences or privileges senior to those of holders of common stock. We cannot assure you that we will be able to raise equity capital, obtain capital lease or bank financing or incur other indebtedness to fund any business combination or the working capital and other capital requirements of a new operating business on terms deemed by us to be commercially acceptable and in our best interests.

OUR ABILITY TO ATTRACT AND RETAIN KEY PERSONNEL MAY BE LIMITED.

Our future success depends on our ability to attract and retain key management and other personnel with expertise required in connection with the acquisition and/or growth and development of a new business. We cannot assure you that we will be successful in attracting and retaining such executives and personnel. Inability to attract and retain qualified personnel and the loss of services of key personnel could have a material adverse effect on our ability to acquire and/or enter new businesses and on our results of operations.

WE WILL FACE INTENSE COMPETITION AS WE SEEK TO COMPLETE ACQUISITIONS AND
OTHER BUSINESS COMBINATIONS.

We will be a small participant in the market of seeking mergers with and acquisitions of all or a portion of other entities. We expect to encounter intense competition from other entities having business objectives similar to ours. Many of these entities are well-established and have extensive experience in identifying and effecting business combinations directly or through affiliates. Many of these competitors possess greater financial, technical, human and other resources than ours and we cannot assure you that we will have the ability to compete successfully. Our financial resources will be limited in comparison to those of many of our competitors. We cannot assure you that we will be able to achieve our stated business objectives.

WE MAY ISSUE NEW EQUITY IN ORDER TO HELP ATTAIN OUR NEW BUSINESS PLAN.

Generally, the board of directors has the power to issue new equity (to the extent of authorized shares) without shareholder approval, except that shareholder approval may be required under applicable law or Nasdaq National Market rules for certain transactions. We may issue new equity to raise additional capital in connection with a business combination or venture transaction with an operating business. Any additional issuance by us would have the effect of diluting the percentage ownership of our shareholders, could have the effect of diluting our earnings and our book value per share, could result in shareholders of another company obtaining a controlling interest in us, and could result in the adverse tax consequences described above.

18

WE RECENTLY SOLD OUR REINSURANCE OPERATIONS, AND MAY HAVE LIABILITY TO THE
PURCHASER AND CONTINUING LIABILITY ON OUR REINSURANCE OPERATIONS.

On May 5, 2000, we sold our reinsurance operations to Folksamerica. In connection with that sale, we made extensive representations and warranties about us and our reinsurance operations, some of which survived the closing of the asset sale. Breach of these representations and warranties could result in liability to us. We also retained our tax and employee benefit liabilities and other liabilities not assumed by Folksamerica, including all liabilities not arising under our reinsurance subsidiary's reinsurance agreements transferred to Folksamerica. For a description of certain risks relating to the asset sale, see "Business--Significant 2000 Developments--Sale of Reinsurance Operations" and note 2 to the notes accompanying our consolidated financial statements.

WE CURRENTLY DO NOT ANTICIPATE PAYING DIVIDENDS.

Any determination to pay dividends in the future will be at the discretion of our board of directors and will be dependent upon our results of operations, financial condition and other factors deemed relevant by our board of directors. As we own and intend to acquire operating businesses, we will depend on future dividends and other permitted payments from our subsidiaries to pay dividends to our shareholders. Our subsidiaries' ability to pay dividends, as well as our ability to pay dividends, is, and is expected to be, subject to regulatory, contractual and other constraints. Our board of directors currently does not intend to declare dividends or make any other distributions.

ITEM 2. PROPERTIES

ACGL maintains its principal offices in Hamilton, Bermuda. ACGL occupies approximately 4,200 square feet of office space in a building located in Greenwich, Connecticut, under a sublease agreement expiring in October 2002. ACGL sub-subleases to MMC Capital the balance of the office space in the building for a term also expiring in October 2002.

Hales leases an aggregate of approximately 7,500 square feet of office space in Chicago, Illinois, New York, New York, Hartford, CT, Mercer Island, Washington and San Francisco, California under leases that expire from June 2002 through February 2009, and American Independent leases approximately 18,000 square feet of office space in Plymouth Meeting, Pennsylvania under a lease that expires in July 2002.

Future minimum rental charges for ACGL, Hales and American Independent for the remaining terms of their subleases, exclusive of escalation clauses and maintenance costs and net of rental income, will be approximately $1,968,700. For 2000, 1999 and 1998, our rental expense, net of sublease income, was approximately $190,000, $576,000 and $576,000, respectively.

We believe that the above described office space is adequate for our current and anticipated needs.

ITEM 3. LEGAL PROCEEDINGS

Our insurance subsidiaries are involved in ordinary routine litigation and arbitration proceedings incidental to their insurance business. We do not believe that there are any material pending legal proceedings to which ACGL or any of its subsidiaries is a party or of which any of their property is subject.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER MATTERS

MARKET INFORMATION

Since the completion of our internal reorganization transaction on November 8, 2000 pursuant to which Arch-U.S. became a wholly owned subsidiary of ACGL (see "Business--General--Reorganization" above), the common shares of ACGL are traded on the Nasdaq National Market under the symbol "ACGL." Prior thereto, from September 13, 1995 to November 8, 2000, the common shares of Arch-U.S. traded on the Nasdaq National Market under the symbol (1) "RCHI" from September 13, 1995 to May 9, 2000 and (2) "ACGL" from May 9, 2000 to November 8, 2000.

DIVIDENDS

Any determination to pay dividends in the future will be at the discretion of our board of directors and will be dependent upon our results of operations, financial condition and other factors deemed relevant by our board of directors. As we own and intend to acquire operating businesses, we will depend on future dividends and other permitted payments from our subsidiaries to pay dividends to our shareholders. Our subsidiaries' ability to pay dividends, as well as our ability to pay dividends, is, and is expected to be, subject to regulatory, contractual and other constraints. Our board of directors currently does not intend to declare dividends or make any other distributions.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis should be read in conjunction with our accompanying consolidated financial statements and notes thereto.

GENERAL

THE COMPANY

ACGL, a Bermuda company formed in September 2000, is a diversified financial services holding company, with an emphasis on the insurance sector. In November 2000, ACGL became the sole shareholder of Arch-U.S. pursuant to the internal reorganization transaction described below. Arch-U.S. commenced operations in September 1995 following the completion of its initial public offering. Prior to May 5, 2000, Arch-U.S. provided reinsurance and other forms of capital for insurance companies through its wholly owned subsidiary, Arch Re. On May 5, 2000, Arch-U.S. sold the reinsurance operations of Arch Re to Folksamerica Reinsurance Company in an asset sale. See note 2 of the notes accompanying our consolidated financial statements and "Business--Significant 2000 Developments--Sale of Reinsurance Operations." Following the asset sale, we have made two acquisitions and have announced a third acquisition in furtherance of our strategy.

REORGANIZATION

On November 8, 2000, following the approval of Arch-U.S.'s shareholders, Arch-U.S. completed an internal reorganization that resulted in Arch-U.S. becoming a wholly owned subsidiary of ACGL. ACGL performs the holding company functions previously conducted by Arch-U.S., and the shareholders of Arch-U.S. have become the shareholders of ACGL. Prior to the reorganization, ACGL had no significant assets or capitalization and had not engaged in any business or prior activities other than in connection with the reorganization. Arch-U.S. remains the holding company for Hales, Arch Re and Cross River Insurance Company, our U.S. subsidiaries.

LIQUIDITY AND CAPITAL RESOURCES

We are a holding company whose assets primarily consist of the stock of our subsidiaries and invested assets totaling $220 million at December 31, 2000, which assets were distributed to us by Arch-U.S. in connection with our Bermuda redomestication. We continuously investigate possible acquisitions of new businesses in support of our strategy and evaluate the retention or disposition of our existing subsidiaries and investments. Accordingly, while we do not currently have any material arrangements or commitments with respect thereto (except as disclosed in this report), we intend to make further acquisitions, and it is possible that divestitures and changes in capital structure could occur. 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. Our board does not currently intend to declare any dividends or make any other distributions. See "Market for Registrant's Common Equity and Related Shareholder Matters--Dividends" and "Risk Factors."

As of December 31, 2000, we had $75.8 million of cash and short-term investments (of which $10.75 million was used in connection with our acquisition of, and related capital contribution to, American Independent in February 2001), $28.6 million of fixed maturity investments, and $49.4 million of publicly traded equity securities. As of that date, investments that are restricted or generally unavailable for liquidity purposes included $44.8 million of privately held securities and $21.0 million of fixed maturity investments held in escrow in connection with the sale of our reinsurance operations. In addition, we have an investment commitment relating to our privately held investment in Trident II totaling approximately $18.2 million. See note 4 of the notes accompanying our consolidated financial statements, "Business--Significant 2000 Developments--Sale of Reinsurance Operations" and "--Acquisitions." Amounts discussed above do not include the stock of our subsidiaries.

23

The ability of our insurance subsidiaries, American Independent and Arch Re, to pay dividends or make distributions is dependent on their ability to meet applicable regulatory standards. Based on 2000 results, American Independent may not pay any dividends or make other distributions during 2001 without prior regulatory approval. Due to the distributions made by Arch Re in connection with the XL Capital share repurchase and our redomestication to Bermuda in 2000, Arch Re may not make any distributions without prior regulatory approval until December 2001. See "Business--Regulatory Considerations" and note 11 of the notes accompanying our consolidated financial statements.

Net cash flow from operating activities for the years ended December 31, 2000, 1999 and 1998 was approximately $2.6 million, $7.5 million and $68.5 million, respectively. For the period from January 1, 2000 to May 5, 2000 and for the years ended December 31, 1999 and 1998, cash flow included premiums received and investment income (excluding net realized investment gains), offset by operating costs and expenses. For the three years ended December 31, 2000, cash flow included investment income (excluding net realized investment gains), offset by operating costs and expenses. Our future net cash flow will depend on the receipt of dividends and other distributions from our subsidiaries and proceeds on the disposition of such subsidiaries, as well as investment income and proceeds on the sale or maturity of our investments.

We expect that our 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 investment income and proceeds on the sale or maturity of our investments. We will continue to pursue and investigate possible business combinations and ventures with new operating businesses in furtherance of our strategy. In that connection, we may need to secure additional financing to carry out our business plan. We cannot assure you that we will be successful in obtaining any such financing or in the implementation of our business plan. See "Risk Factors."

ACQUISITIONS

On December 4, 2000, we acquired Hales & Company, a merchant banking firm specializing in the insurance industry. See "Business--Acquisitions" above. In addition to providing us with a growing franchise in the insurance services sector, the employees of Hales assist us in finding acquisition candidates, evaluating them, conducting due diligence and monitoring acquired businesses.

On February 28, 2001, we acquired one of our investee companies, American Independent Insurance Company. American Independent underwrites private passenger automobile liability and physical damage insurance primarily in the Commonwealth of Pennsylvania. See "Business--Acquisitions" above. On an ongoing basis we will determine how much of the insurance premium underwritten by American Independent will be retained by us and how much commission income we will capture through the purchase of reinsurance.

On March 23, 2001, we entered into a reorganization agreement for the acquisition of all of the remaining ownership interests in Altus Holdings, Ltd., which provides insurance and alternative risk transfer services through rent-a-captive and other facilities. See "Business--Acquisitions" above. The Altus group includes First American Insurance Company, an admitted insurer in 49 states with an A.M. Best rating of "A-."

FINANCIAL CONDITION

At December 31, 2000, our consolidated shareholders' equity totaled $275.3 million, or $21.66 per share on a diluted basis, based on 12,709,579 common shares outstanding, compared to our consolidated shareholders' equity at December 31, 1999 of $346.5 million, or $20.28 per share on a diluted basis, based on 17,087,970 shares outstanding. The decrease in consolidated shareholders' equity primarily resulted from our share repurchase on March 2, 2000 from XL Capital of all of the 4,755,000 common shares held by it for a repurchase price of $59.2 million, or $12.45 per share. We paid XL the consideration for the repurchase with our ownership interests in LARC Holdings and Annuity & Life Re. XL paid us in cash the $3.6 million difference between the repurchase price and the value of such investments. See note 13 of the notes accompanying our consolidated financial statements.

Our aggregate invested assets, including cash and short-term investments, totaled $279.1 million at December 31, 2000, compared to $585.9 million at December 31, 1999. The decrease in cash and invested

24

assets from 1999 to 2000 resulted from the transfers of (1) $248.2 million of fixed maturities and short-term investments to Folksamerica at the closing of the sale of Arch Re's reinsurance operations and (2) $59.2 million of privately held securities in consideration for the shares repurchased from XL Capital.

INVESTMENTS

Prior to the sale of our reinsurance operations on May 5, 2000, our investment goals had been to support Arch Re's reinsurance activities. Following the asset sale, we have sought to acquire operating companies in support of our business plan of building a diversified financial services holding company. See "Business--General--Strategy" and "Business--Acquisitions" above.

At December 31, 2000, consolidated cash and invested assets totaled approximately $279.1 million, consisting of $108.9 million of cash and short-term investments, $38.5 million of publicly traded fixed maturity investments, $21.0 million of fixed maturities held in escrow, $51.3 million of publicly traded equity securities, and $59.4 million of privately held securities.

As a significant portion of our investment portfolio consists of equity securities issued by insurance and reinsurance companies and companies providing services to the insurance industry, our equity portfolio lacks industry diversification and will be particularly subject to the performance of the insurance industry. Unlike fixed income securities, equity securities such as common stocks, including the equity securities in which we have invested, generally are not and will not be rated by any nationally recognized rating service. The values of equity securities generally are more dependent on the financial condition of the issuer and less dependent on fluctuations in interest rates than are the values of fixed income securities. The market value of equity securities generally is regarded as more volatile than the market value of fixed income securities. Since the realization of gains and losses on equity investments is not generally predictable, such gains and losses have differed and will differ significantly from period to period. Variability and declines in our results of operations could be further exacerbated by private equity investments in start-up companies which are accounted for under the equity method. Such start-up companies may be expected initially to generate operating losses. The effects of such volatility on our equity portfolio could be exacerbated to the extent that such portfolio is concentrated in the insurance industry and in relatively few issuers. For additional discussion, see "--Market Sensitive Instruments and Risk Management" below.

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. 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.

At December 31, 2000, our private equity portfolio consisted of 11 investments, with additional investment portfolio commitments in an aggregate amount of approximately $22.6 million.

See note 4 under the caption "Investment Information" of the notes accompanying our consolidated financial statements for certain information regarding our publicly traded and privately held securities and their carrying values, and commitments made by us relating to our privately held securities.

On February 28, 2001, we completed a reorganization transaction pursuant to which we acquired all of the common stock of American Independent Insurance Holding Company, one of our investee companies. On March 23, 2001, we entered into a reorganization agreement for the acquisition of the remaining ownership interests in Altus Holdings, Ltd., another of our investee companies. See "Business--Acquisitions" above and note 15 of the notes accompanying our consolidated financial statements.

At December 31, 2000, approximately 100% of our fixed maturity and short-term investments were rated investment grade by Moody's or Standard & Poor's and had an average quality rating of AA and an average duration of approximately 1.3 years. In November 2000, we liquidated our high yield portfolio in connection

25

with our reorganization transaction. In January 2001, we began to reinvest approximately $35 million of cash in high yield fixed maturity investments. At March 15, 2001, we had approximately $33 million of such funds invested in high yield investments, with an average quality rating of BB- and an average duration of 4.4 years.

We have not invested in derivative financial instruments such as futures, forward contracts, swaps, or options or other financial instruments with similar characteristics such as interest rate caps or floors and fixed-rate loan commitments. Our portfolio includes market sensitive instruments, such as mortgage-backed securities, which are subject to prepayment risk and changes in market value in connection with changes in interest rates. Our investments in mortgage-backed securities, which amounted to approximately $5.5 million at December 31, 2000, or 2% of cash and invested assets, are classified as available for sale and are not held for trading purposes.

RESULTS OF OPERATIONS

SFAS No. 131 requires certain disclosures about operating segments in a manner that is consistent with how management evaluates the performance of the segment.

Prior to the sale of our reinsurance operations, we operated in one reportable business segment, which was providing property and casualty reinsurance and other forms of capital to insurance and reinsurance companies and making investments in insurance and insurance-related entities on a global basis. This segment included the results of Arch Re and Cross River, and consisted primarily of the premiums, claims and claims expenses, other operating expenses and investment results.

Since the sale of our reinsurance operations, we have operated in one reportable business segment during 2000. The financial results of Hales, which was acquired during December 2000, were not material for the year ended December 31, 2000. See note 12 of the notes accompanying our consolidated financial statements for information concerning the company's business.

Prior to the sale of our reinsurance operations, we had consolidated comprehensive losses of $17.5 million, $52.3 million and $4.4 million for the years ended December 31, 2000, 1999 and 1998, respectively. Our comprehensive income or loss is composed of net income and the change in unrealized appreciation of investments. Net loss for the years ended December 31, 2000 and 1999 was $8.7 million and $32.4 million, respectively, and net income for the year ended December 31, 1998 was $3.1 million. Such financial results include the underwriting results of our divested reinsurance operations and are not indicative of future results. Other comprehensive loss for the years ended December 31, 2000, 1999 and 1998 was $8.8 million, $19.9 million and $7.5 million, respectively. For 2000, 1999 and 1998, net income (loss) included after-tax realized investment gains of $9.5 million, $11.2 million and $16.4 million, respectively, and equity in the net income (loss) of investee companies accounted for under the equity method of accounting of $1.3 million, $0.7 million and ($1.1 million), respectively.

26

A table of per share data for the years ended December 31, 2000, 1999 and 1998 on an after-tax basis follows. As detailed below, our consolidated net loss for the year ended December 31, 2000 has been affected by (1) net realized after-tax investment gains of $9.5 million, which include $9.8 million in after-tax realized losses resulting primarily from restructuring our investment portfolio in connection with our redomestication to Bermuda on November 8, 2000;
(2) the loss on the sale of Arch Re's reinsurance operations to Folksamerica on May 5, 2000; (3) the recording of a loss contingency of $15 million, on a pre-tax basis, against the $20 million of assets held in escrow in connection with the sale of Arch Re's reinsurance operations to recognize a probable deficiency in the related reserves; and (4) poor underwriting results from our divested reinsurance operations prior to the sale on May 5, 2000. Each of these items is discussed below.

RESERVE FOR CONTINGENT LOSS OF ESCROWED ASSETS

In connection with the sale of Arch Re's reinsurance operations to Folksamerica on May 5, 2000, we placed $20 million of the purchase price in escrow for a period of five years. These funds will be used to reimburse Folksamerica if the loss reserves (which were $32.3 million at May 5, 2000) transferred to it in the asset sale relating to business produced on behalf of Arch Re by a certain managing underwriting agency are deficient as measured at the end of such five-year period or to satisfy certain indemnity claims Folksamerica may have during such period. In connection with the escrow arrangement, we will record a loss in an amount equal to any probable deficiency in the related reserve that may become known during or at the end of the five-year period. If such loss reserves are redundant, all of the escrowed funds will be released from escrow to us and Folksamerica will pay us an amount equal to such redundancy. As required under the agreement, Folksamerica reported to us that adverse development had occurred in the loss reserves subject to the escrow agreement for the period from May 5, 2000 to December 31, 2000. Based on such information and an independent actuarial analysis, we recorded in the 2000 fourth quarter a loss contingency of $15 million, on a pre-tax basis, to recognize an estimated probable deficiency in such reserves. The actuarial analysis was based on estimates of claims and claims expenses incurred as of December 31, 2000 and, therefore, the amount ultimately paid may be more or less than such estimate. See "Business--Significant 2000 Developments--Sale of Reinsurance Operations" and note 2 of the notes accompanying our consolidated financial statements.

NET INVESTMENT INCOME

At December 31, 2000, approximately 53% of our invested assets consisted of fixed maturity and short-term investments, exclusive of securities held in escrow, compared to 59% at December 31, 1999. Net investment income was approximately $15.9 million in 2000, compared to $20.2 million and $15.7 million in 1999 and 1998, respectively. Such amounts for 2000, 1999 and 1998 are net of investment expenses of $858,000, $5.5 million and $3.6 million, respectively. The investment expense amounts include investment advisory fees of $0.8 million, $2.0 million and $3.3 million, respectively. The 2000 net investment expenses are offset by advisory fee income that we received from MMC Capital in the amount of $1.25 million. Please refer to note 5 of the notes accompanying our consolidated financial statements for additional information about our investment advisory agreement with MMC Capital. The 1999 net investment income is also net of $1.1 million for the payment of interest expense in connection with the settlement of satellite losses.

The decrease in net investment income in 2000 compared with 1999 primarily reflected the decline in our average invested asset base resulting from the sale of Arch Re's reinsurance operations, partially offset by the decrease in investment expenses described above and a higher interest rate environment. The increase in net investment income in 1999 compared with 1998 reflected an increase in our average invested asset base and an increase in the annualized effective yield on our portfolio.

Our investment yields at amortized cost were as follows for the periods set forth below:

Net of tax                   3.1%          2.7%            2.5%

Our investment yields reflect a significant allocation of the total investment portfolio in equity securities, which yield less current income than fixed maturity investments. At December 31, 2000, 1999 and 1998, investments in public and private equity securities approximated 40%, 41% and 49%, respectively, of total cash and invested assets. Additionally, such investment yields exclude the equity in the net income or loss of private equity investments accounted for under the equity method.

In 2000, net realized gains include $11.0 million of pre-tax losses, or $8.7 million after-tax, recorded during the 2000 fourth quarter resulting from the restructuring of our investment portfolio in connection with our redomestication to Bermuda on November 8, 2000. In addition, we recorded a pre-tax realized loss of $1.7 million, or $1.1 million, after-tax, that adjusted the cost basis on two publicly traded equity securities held in our portfolio to a new cost basis to recognize an "other than temporary" decline in their respective market values. While the effect of recording this loss of $1.7 million reduced net income, such loss had no impact on our shareholders' equity because such investments are carried in the consolidated balance sheet at market value with unrealized losses, net of tax, reported as a separate component of shareholders' equity.

OTHER COMPREHENSIVE INCOME

For 2000, the change in after-tax net unrealized appreciation of investments of $8.8 million reflects the following (in millions):

INCOME TAXES

Under current Bermuda law, ACGL is not obligated to pay any taxes in Bermuda based upon income or capital gains. We have 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 appreciation on any capital asset, or any tax in the nature of estate duty or inheritance tax, such tax will not be applicable to us or our 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 United States and is not exempt from U.S. tax under an applicable income tax treaty with the United States. ACGL will be subject to a withholding tax on dividends from U.S. investments and interest from certain U.S. payors. ACGL does not consider itself to be engaged in a trade or business within the United States and, consequently, does not expect to be subject to direct U.S. income taxation. ACGL's U.S. subsidiaries will continue to be subject to U.S. income taxes on their worldwide income.

Arch-U.S.'s 2000 income tax expense was $5.4 million, compared with an income tax benefit of $19.6 million in 1999 and an income tax expense of $235,000 in 1998. In 2000, income tax expense on our pre-tax net loss included a charge to establish a valuation allowance of $5.7 million that adjusted Arch U.S.'s deferred income tax asset to its estimated realizable value. Income tax expense for 2000 also included the write-off of a deferred tax asset of $1.7 million relating to an investee company in connection with our redomestication to Bermuda. In addition, Arch-U.S.'s effective tax rate in 2000 of 49% on equity in net income of investees differs from the U.S. federal statutory rate of 35%. This higher effective rate primarily reflects the write-off of a deferred tax asset of $374,000 relating to an investee company recorded under the equity method of accounting in connection with our redomestication. In 1999, Arch Re's underwriting results had significantly deteriorated resulting in a pre-tax net loss that generated an income tax benefit for the year. In 1998, income tax expense was less than the U.S. federal statutory rate due to tax-exempt dividends and interest income.

The net deferred income tax asset at December 31, 2000 was $8.2 million, compared with $7.8 million at December 31, 1999. As of December 31, 2000, Arch-U.S. has a valuation allowance of $5.7 million that adjusts the net deferred income tax asset to its estimated realizable value of $8.2 million. At December 31, 1999, Arch-U.S. did not have a valuation allowance because it believed at that time that its entire deferred tax asset was realizable due to its ability to generate future taxable income.

As a result of its net operating losses in 2000 and 1999, Arch-U.S. has net operating loss carryforwards totaling $35.6 million at December 31, 2000. Such net operating losses are currently available to offset future taxable income of Arch-U.S. with the following expiration dates: $18.3 million expiring in 2019 and $17.3 million expiring in 2020.

Upon our redomestication to Bermuda, Arch-U.S. distributed substantially all of its public equity portfolio to its Bermuda parent, ACGL, at the current market values and realized gains for tax purposes of $21,044,000. The associated income tax expense of $7,365,000 reduced Arch-U.S.'s net operating loss carryforwards by such amount. However, for financial reporting purposes, since the securities have not been sold to an unrelated third party, the realized gain has been deferred and is reported as unrealized appreciation in our consolidated financial statements. Accordingly, the income tax expense is also deferred and reduces unrealized appreciation in the consolidated financial statements.

The repurchase of our common shares held by XL Capital resulted in a 27.8% change in ownership by 5% shareholders. If, in the ensuing three years, there is more than a 22.2% additional change in ownership by 5% shareholders, an "ownership change" will have taken place for federal income tax purposes. If such ownership change occurs, the amount of loss carryforwards that can be used in any subsequent year may be severely limited and could be eliminated in certain circumstances.

See notes 10 and 13 of the notes accompanying our consolidated financial statements.

For the period January 1, 2000 through the sale of Arch Re's reinsurance operations on May 5, 2000, 26.3% of premiums written were from the accident and health class of business and 28% were from the property and multi-line classes of business. Retrocessional premium for aviation business exceeded assumed premiums written by $1.9 million.

Arch Re's net premiums written increased 31% to $306.7 million in 1999 from $234.7 million in 1998. Premium growth resulted from two key strategies, the integration of investment with reinsurance and the diversification into "specialty" classes of business, which for purposes of this discussion consist of accident & health, aviation & space, marine and surety & fidelity.

Net premiums written in 1999 included approximately $26 million related to a group of property reinsurance treaties that expired in 1999 covering crop hail business underwritten on behalf of a start-up entity formed by Trident II, L.P. This business was protected by extensive aggregate excess of loss retrocession and generated a profit based upon underwriting results.

Net premiums written in 1999 for other business was reduced by $10.6 million for the retrocession of a treaty which covered future multiple rocket launches that was recorded in 1996. The reduction of net premiums written resulting from this retrocession increased the commission and operating expense ratio components of the statutory composite ratio by 1.1 percentage points, but had no impact on operating results.

Arch Re's ceded premiums were $19.7 million in 2000, $80.1 million in 1999, and $25.8 million in 1998. Such ceded premiums primarily related to Arch Re's property, multi-line, marine, aviation and space reinsurance business, for which the Company sought to reduce Arch Re's exposure to large and catastrophic losses. In 2000 and 1999, the Company purchased additional retrocessional protection to reduce Arch Re's exposures to both space and aviation risks, and to earthquake, wind and other property catastrophe perils. See "--Results of Operations--Space & Aviation Business Relating to Divested Reinsurance Operations" and note 8 of the notes accompanying our consolidated financial statements.

OPERATING COSTS AND EXPENSES RELATING TO DIVESTED REINSURANCE OPERATIONS

The statutory combined ratio is one traditional method of measuring the underwriting performance of a property/casualty insurer. This ratio, which is based upon statutory accounting principles (which differ from generally accepted accounting principles in several respects), reflects underwriting experience, but does not reflect income from investments. A statutory combined ratio under 100% indicates underwriting profitability, while a combined ratio exceeding 100% indicates an underwriting loss.

With respect to Arch Re's reinsurance operations, which were divested May 5, 2000, set forth below are Arch Re's statutory combined ratios for the years ended December 31, 2000, 1999 and 1998:

   Amount                         $ 19.0         $ 58.4        $ 23.0

Arch Re's 2000 combined ratio was adversely effected by underwriting results from our property, multi-line and aviation & space business. Arch Re's 1999 and 1998 statutory combined ratios were adversely affected by underwriting results from business written by a managing general agency and our space and aviation classes of business.

MANAGING UNDERWRITING AGENCY RELATING TO DIVESTED REINSURANCE OPERATIONS

During 1999 and 1998, Arch Re recorded after-tax underwriting losses of $16.5 million, or $0.96 per share, and $6.5 million, or $0.38 per share, respectively, from reinsurance on casualty and multi-line business produced by the managing underwriting agency. Such business increased the combined ratio by 7.7 points and 4.1 points in 1999 and 1998, respectively. Arch Re also recorded related after-tax investment losses of $1.3 million, or $0.07 per share, and $862,000, or $0.03 per share, in net realized investment losses in 1999 and 1998, respectively. Arch Re discontinued its underwriting relationship with the managing underwriting agency in 1999.

32

Net reserves for claims and claims expenses for this business approximated $32.3 million at May 5, 2000, the closing date of the sale of Arch Re's reinsurance operations. See "--Results of Operations--Reserve for Contingent Loss of Escrowed Assets," "Business--Significant 2000 Developments--Sale of Reinsurance Operations" and note 2 of the notes accompanying our consolidated financial statements for a discussion of a $20 million escrow fund relating to such reserves established in connection with the sale of our reinsurance operations to Folksamerica.

SPACE & AVIATION BUSINESS RELATING TO DIVESTED REINSURANCE OPERATIONS

During 2000, 1999 and 1998, Arch Re recorded after-tax underwriting losses of $6.1 million, or $0.46 per share, $19.7 million, or $1.15 per share, and $7.8 million, or $0.46 per share, respectively, for its space and aviation lines of business. The effect on the combined ratio in 2000 from such losses is meaningless because net premiums written were negative due to ceded premiums written. Underwriting losses increased the combined ratio by 8.3 and 4.9 points in 1999 and 1998, respectively. During 1999, Arch Re discontinued both lines of business; however, exposures continued post-1999 from multi-year treaties and treaties in run-off.

Included in the 1999 after-tax underwriting loss for aviation business are incurred losses for the 1998 Swiss Air and Korean Air crashes and certain 1999 crashes, including the Egypt Air, American Airlines, Korean Air and China Air crashes. The additional loss recorded in 1999 for the Swiss Air crash was based on a reallocation of the $642 million expected industry loss between the plane manufacturer and Swiss Air. This reallocation adversely affected Arch Re's gross loss. The gross loss associated with the Swiss Air crash reported as of December 31, 1998 had exhausted Arch Re's retrocessional protections applicable to this occurrence. Therefore, none of such additional loss reported was ceded to retrocessionaires.

In connection with the sale of Arch Re's reinsurance operations, we purchased additional reinsurance protection to reduce the net financial loss to Folksamerica on any large commercial airline catastrophe to $5.4 million, net of reinstatement premiums. Although we believe that any such net financial loss will not exceed $5.4 million, we have agreed to reimburse Folksamerica for a net financial loss it may incur that is in excess of $5.4 million for aviation losses under certain circumstances prior to May 5, 2003. See "Business--Significant 2000 Developments--Sale of Reinsurance Operations" and note 2 of the notes accompanying our consolidated financial statements.

OTHER UNDERWRITING LOSS ACTIVITY RELATING TO DIVESTED REINSURANCE OPERATIONS

All other classes of business also contributed to the 2000 and 1999 underwriting losses (except for multi-line in 1999), with the largest contribution for 1999 from property business. The after-tax underwriting loss for 1999 property business approximated $4.9 million, which included after-tax losses of $4.3 million for two large catastrophes in 1999 (Rouge steel plant in Dearborn, Michigan, and French storm losses).

The 1998 underwriting loss included an after-tax underwriting loss of $3.3 million for a property loss on a finite risk treaty.

PRIOR YEAR DEVELOPMENT RELATING TO DIVESTED REINSURANCE OPERATIONS

Estimates of prior accident year claims were increased by approximately $3 million in 2000 primarily relating to Arch Re's aviation and property business. Estimates of prior accident year claims were increased by approximately $30 million in 1999, which added 10.2 points to the 1999 combined ratio. A substantial portion of the 1999 increase resulted from (1) business produced by the managing underwriting agency, (2) notification of additional satellite losses received in 1999 pertaining to 1998, (3) aviation losses, principally the previously discussed 1998 Swiss Air crash, and (4) property losses reported on several international treaties that were in run-off.

Estimates of prior accident year claims were reduced by approximately $2.8 million in 1998 primarily due to favorable claim development in the property and multi-line classes of business.

33

ACQUISITION COSTS RELATING TO DIVESTED REINSURANCE OPERATIONS

Commissions and brokerage expenses are acquisition costs that generally vary by the type of treaty and line of business, and were considered by Arch Re's underwriting and actuarial staff in evaluating the adequacy of premium writings prior to the sale of Arch Re's reinsurance operations. In a number of reinsurance treaties, provisional commissions were initially paid and subsequently increased or decreased, subject to a minimum and maximum amount, depending upon the claims and claims expenses experience of the assumed business. Arch Re recorded the commission increase or decrease in accordance with contractual terms based on the expected ultimate experience of the contract. The claims and commissions and brokerage ratios reflected Arch Re's business mix.

OTHER OPERATING EXPENSES RELATING TO DIVESTED REINSURANCE OPERATIONS

Other operating expenses were $8.0 million in 2000, compared to $14.8 million and $16.5 million for the years ended December 31, 1999 and 1998, respectively.

For 2000, our operating expenses decreased 46% primarily reflecting reduced operating costs resulting from the sale of Arch Re's reinsurance operations on May 5, 2000.

For 1999, our statutory operating expense ratio declined to 4.7%, compared with 6.8% for 1998. The decline in the operating expense ratio was due to a decrease in other operating expenses and an increase in Arch Re's net premiums written from the comparable prior year period. In addition, commencing in 1999, we allocated certain compensation and other operating expenses related to investment activities in the amount of $2.1 million to net investment income based on internal time studies. Such allocations were not made in prior periods. Due to such allocations, the 1999 statutory operating expense ratio improved by approximately one point and net investment income was reduced by approximately $0.08 per share, with no overall effect on operating results. On a pro-forma basis, the statutory operating expense ratio for 1998 would have been 5.8%.

FOREIGN EXCHANGE RELATING TO DIVESTED REINSURANCE OPERATIONS

For the period January 1, 2000 through the sale of Arch Re's reinsurance operations on May 5, 2000, and for the years ended December 31, 1999 and 1998, the company recorded pre-tax foreign exchange gains and losses separately from statutory underwriting results and such gains and losses were therefore excluded from the statutory combined ratios. Unhedged monetary assets and liabilities prior to May 5, 2000 were translated at the exchange rate in effect at the balance sheet date, with the resulting foreign exchange gains or losses recognized in income. For the period January 1, 2000 through May 5, 2000, and for the years ended December 31, 1999 and 1998, pre-tax foreign exchange gains and (losses) were ($1,159,000), $198,000 and $443,000, respectively. At December 31, 2000, all of our assets and liabilities were denominated in U.S. dollars.

MARKET SENSITIVE INSTRUMENTS AND RISK MANAGEMENT

In accordance with the SEC's Financial Reporting Release No. 48, the following analysis presents hypothetical losses in cash flows, earnings and fair values of market sensitive instruments which are held by us as of December 31, 2000 and are sensitive to changes in interest rates and equity security prices. This risk management discussion and the estimated amounts generated from the following sensitivity analysis represent forward-looking statements of market risk assuming certain adverse market conditions occur. Actual results in the future may differ materially from these projected results due to actual developments in the global financial markets. The analysis methods used by us to assess and mitigate risk should not be considered projections of future events of losses.

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. The focus of the SEC's market risk rules is on price risk. For purposes of specific risk analysis, we employ 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.

The financial instruments included in the following sensitivity analysis consist of all of our cash and invested assets, excluding investments carried under the equity method of accounting.

34

EQUITY PRICE RISK

We are exposed to equity price risks on the public and private equity securities included in our investment portfolio. All of our publicly traded equity securities and privately held securities were issued by insurance and reinsurance companies or companies providing services to the insurance industry. We typically do not attempt to reduce or eliminate our market exposure on these securities. 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. Investments in privately held securities issued by privately held companies may include both equity securities and securities convertible into, or exercisable for, equity securities (some of which may have fixed maturities).

Our publicly traded and privately held equity securities at December 31, 2000, which are carried at a fair value of $51.3 million and $59.4 million, respectively, have exposure to price risk. The estimated potential losses in fair value for our publicly traded and privately held equity portfolios resulting from a hypothetical 10% decrease in quoted market prices, dealer quotes or fair value are $5.1 million and $5.9 million, respectively.

INTEREST RATE RISK

The aggregate hypothetical loss generated from an immediate adverse shift in the treasury yield curve of 100 basis points would result in a decrease in total return of 2.2%, which would produce a decrease in market value of $1.3 million on our fixed maturity investment portfolio valued at $59.5 million (including securities held in escrow) at December 31, 2000. There would be no material impact on our short-term investments.

RECENT ACCOUNTING PRONOUNCEMENTS

See note 3 of the notes accompanying our consolidated financial statements for a description of recent accounting pronouncements. The impact of adopting new accounting pronouncements will not materially affect our financial condition and/or results of operations.

INSURANCE REGULATION

Our insurance subsidiaries, in common with other insurers, are subject to extensive governmental regulation and supervision in the various states and jurisdictions in which it transacts business. The laws and regulations of the insurer's state of domicile have the most significant impact on its operations.

From time to time various regulatory and legislative changes have been proposed in the insurance and reinsurance industry. Among the proposals that have in the past been, or are at present being considered, are (1) the possible introduction of federal regulation in addition to, or in lieu of, the current system of state regulation of insurers and (2) proposals in various state legislatures (some of which proposals have been enacted) to conform portions of their insurance laws and regulations to various model acts adopted by the NAIC. We are unable to predict whether any of such laws and regulations will be adopted, the form in which any such laws and regulations would be adopted, or the effect, if any, these developments would have on our operations and financial condition. See "Business--Regulatory Considerations."

In March 1998, the NAIC adopted the codification of statutory accounting principles project that will generally be applied to all insurance and reinsurance company financial statements filed with insurance regulatory authorities as early as the statutory filings made in 2001. Although the codification is not expected to materially affect many existing statutory accounting practices presently followed by most insurers and reinsurers, there are several accounting practices that may be changed. As of December 31, 2000, we have estimated that, on a consolidated basis, there will be no effect on surplus as a result of the adoption of the codification.

REPORT OF INDEPENDENT ACCOUNTANTS

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

In our opinion, the accompanying consolidated balance sheet and the related consolidated statements of income and comprehensive income, of changes in shareholders' equity and of cash flows present fairly, in all material respects, the financial position of Arch Capital Group Ltd. and its subsidiaries at December 31, 2000 and 1999, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2000 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. FORMATION, CAPITALIZATION AND BUSINESS

THE COMPANY

Arch Capital Group Ltd., a Bermuda company with principal offices in Bermuda ("ACGL"), is a diversified financial services holding company, with an emphasis on the insurance sector. ACGL was formed in September 2000 to accomplish the internal reorganization transaction described below involving Arch Capital Group (U.S.) Inc. (formerly known as (i) "Risk Capital Holdings, Inc." from March 1995 to May 8, 2000 and (ii) "Arch Capital Group Ltd." from May 8, 2000 to November 8, 2000), a Delaware holding company formed in March 1995 ("Arch-U.S."). The common shares of ACGL are traded on the Nasdaq National Market under the symbol "ACGL."

REORGANIZATION

On November 8, 2000, following the approval of Arch-U.S.'s shareholders, Arch-U.S. completed an internal reorganization that resulted in Arch-U.S. becoming a wholly owned subsidiary of ACGL. As indicated above, ACGL retained the name of "Arch Capital Group Ltd." and Arch-U.S. was renamed "Arch Capital Group (U.S.) Inc." ACGL performs the holding company functions previously conducted by Arch-U.S., and the shareholders of Arch-U.S. have become the shareholders of ACGL. Prior to the reorganization, ACGL had no significant assets or capitalization and had not engaged in any business or prior activities other than in connection with the reorganization. Arch-U.S. remains the holding company for certain United States subsidiaries.

As used below, the "Company" means ACGL and its subsidiaries, except when referring to periods prior to November 8, 2000, when it means Arch-U.S. and its subsidiaries. Similarly, "Common Shares" means the common shares, par value U.S. $0.01, of ACGL, except when referring to periods prior to November 8, 2000, when it means the common stock of Arch-U.S.

HISTORY

Arch-U.S. is a holding company whose wholly owned subsidiary, Arch Reinsurance Company (formerly known as "Risk Capital Reinsurance Company"), a Nebraska corporation ("Arch Re"), was formed to provide reinsurance and other forms of capital for insurance companies. In September 1995, through its initial public offering, related exercise of the underwriters' over-allotment option and direct sales of 16,750,625 Common Shares, at $20 per share, and the issuance of warrants, Arch-U.S. was capitalized with net proceeds of approximately $335.0 million, of which $328 million was contributed to Arch Re. In July 1998, Arch Re capitalized its wholly owned subsidiary, Cross River Insurance Company ("Cross River"), with $20 million. Cross River received its Nebraska license in October 1998, and is currently authorized to write insurance on an excess and surplus lines basis in 22 other states. On May 5, 2000, Arch-U.S. sold the reinsurance operations of Arch Re to Folksamerica Reinsurance Company in the asset sale described below in Note 2. Following the asset sale, the Company has made two acquisitions and has announced a third acquisition in furtherance of its strategy. See Note 2 and Note 15.

Class A warrants to purchase an aggregate of 2,531,079 Common Shares and Class B warrants to purchase an aggregate of 1,920,601 Common Shares were issued in connection with the direct sales of Common Shares. Class A warrants are immediately exercisable at $20 per share and expire September 19, 2002. Class B warrants are exercisable at $20 per share during the seven-year period commencing September 19, 1998, provided that the Common Shares have traded at or above $30 per share for 20 out of 30 consecutive trading days.

2. ACQUISITIONS AND DISPOSITIONS

HALES & COMPANY

On December 4, 2000, the Company acquired substantially all of the assets of Hales Capital Advisors, LLC, a privately held merchant banking firm specializing in the insurance industry. Founded in 1973, Hales is a merger and acquisition advisor to middle-market insurance organizations and the manager of the general partner of Distribution Partners Investment Capital, L.P., a private equity fund with $51 million of committed capital. Distribution Partners focuses on equity investments in insurance distribution and distribution-related service companies. The purchase price for the Hales assets consisted of 300,000 Common Shares (which shares are subject to a two-year lock-up) and $1.9 million in cash, representing a total purchase price of approximately $6.4 million (based on the closing market price of the Common Shares on December 4). Substantially all of this amount is reflected as goodwill and is being amortized over a period not to exceed 15 years. As part of the acquisition of Hales, the Company has made a commitment of $1.2 million to the general partner of Distribution Partners. See Note 4.

The Hales business is conducted through our newly-formed subsidiary, Hales & Company Inc. Hales provides merger and acquisition advisory, valuation and capital raising services to its clients. Hales' clients include insurance distributors, insurance companies, banks and other financial institutions with interests in insurance distribution.

FOLKSAMERICA TRANSACTION

On May 5, 2000, the Company sold the reinsurance operations of Arch Re pursuant to an agreement entered into as of January 10, 2000 with Folksamerica Reinsurance Company and Folksamerica Holding Company (collectively, "Folksamerica"). Folksamerica Reinsurance Company assumed Arch Re's liabilities under the reinsurance agreements transferred in the asset sale and Arch Re transferred to Folksamerica Reinsurance Company assets estimated in an aggregate amount equal in book value to the book value of the liabilities assumed. In consideration for the transfer of Arch Re's book of business, Folksamerica paid $20.084 million (net of a credit equal to $251,000 granted to Folksamerica for certain tax costs) in cash at the closing, subject to post-closing adjustments based on an independent actuarial report of the claim liabilities transferred and an independent audit of the net assets sold. Following the completion of such report and audit, the parties agreed upon net post-closing adjustments in the amount of approximately $3.2 million payable by the Company, which consisted of a $4.2 million reduction in the purchase price less $1 million in net book value of the assets and liabilities actually transferred at closing.

Under the terms of the agreement, $20 million has been placed in escrow for a period of five years. Such amounts represent restricted funds that appear under a separate caption entitled "Securities held in escrow" on the Company's consolidated balance sheet at December 31, 2000. These funds will 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 by a certain managing underwriting agency are deficient as measured at the end of such five-year period or to satisfy certain indemnity claims Folksamerica may have during such period. In connection with the escrow arrangement, the Company will record a loss in an amount equal to any probable deficiency in the related reserve that may become known during or at the end of the five-year period. If such loss reserves are redundant, all of the escrowed funds will be released from escrow to the Company and Folksamerica will pay the Company an amount equal to such redundancy. The agreement also provided that an additional amount of up to $5 million would be placed in escrow for a period of five years to the extent that Arch Re's reserves at closing on all business other than that covered by the $20 million escrow were less by at least a specified amount than those estimated by its independent actuaries. No such supplemental escrow was required.

As required under the agreement, Folksamerica reported to the Company that adverse development had occurred in the loss reserves subject to the Folksamerica escrow agreement for the period from May 5, 2000 to December 31, 2000. Based on such information and an independent actuarial analysis, the Company recorded in the 2000 fourth quarter a loss contingency of $15 million, on a pre-tax basis, to recognize a probable deficiency in such reserves. The actuarial analysis was based on estimates of claims and claims expenses

incurred as of December 31, 2000 and, therefore, the amount ultimately paid may be more or less than such estimate.

Under the terms of the agreement, the Company has also purchased reinsurance protection covering the Company's 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 for a net financial loss it may incur that is in excess of $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. 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 denies the validity of any such potential claim.

The net book value gain resulting from the sale of the Company's reinsurance operations to Folksamerica is calculated as follows (in thousands):

At the closing of the asset sale, Arch Re and Folksamerica entered into a transfer and assumption agreement, under which Folksamerica assumed Arch Re's rights and obligations under the reinsurance agreements transferred in the asset sale. The reinsureds under such agreements that were in-force were notified that Folksamerica had assumed Arch Re's obligations and that, unless the reinsureds object to the assumption, Arch Re will be released from its obligations to those reinsureds. None of such reinsureds objected to the assumption and, accordingly, the gross liabilities for such business have been removed from the accounts of Arch Re for statutory and GAAP accounting purposes. However, Arch Re 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 may incur losses relating to the reinsurance agreements transferred in the asset sale.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The consolidated financial statements have been prepared in conformity with generally accepted accounting principles ("GAAP") in the United States and include the accounts of ACGL, Arch-U.S., Hales, Arch Re and Cross River. All 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.

F-10

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

PREMIUM REVENUES AND RELATED EXPENSES

With respect to the Company's divested reinsurance operations (see Note 2), premiums were recognized as income on a pro rata basis over the terms of the related reinsurance contracts. These amounts were based on reports received from ceding companies, supplemented by the Company's own estimates of premiums for which ceding company reports had not been received. Unearned premium reserves at December 31, 1999, represent the portion of premiums written that related to the unexpired terms of contracts in force. Certain of the Company's contracts included provisions that adjusted premiums based upon the experience under the contracts. Premiums written and earned as well as related acquisition expenses under those contracts were recorded based upon the expected ultimate experience under those contracts.

Acquisition costs, which vary with and are primarily related to the acquisition of policies, consisting principally of commissions and brokerage expenses incurred at the time a contract is issued, were deferred and amortized over the period in which the related premiums were earned. Deferred acquisition costs were limited to their estimated realizable value based on the related unearned premiums and took into account anticipated claims and claims expenses, based on historical and current experience, and anticipated investment income.

INVESTMENTS

The Company classifies all of its publicly traded fixed maturity 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. Short-term investments, which have a maturity of one year or less at the date of acquisition, are carried at cost, which approximates fair value.

Investments in privately held securities, issued by privately and publicly held companies, may include both equity securities and securities convertible into, or exercisable for, equity securities (some of which may have fixed maturities) and debt securities. Privately held securities are subject to trading restrictions or are otherwise illiquid and do not have readily ascertainable market values. 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 the Company's inability 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 which the Company seeks to sell. Such investments are classified as "available for sale" and carried at estimated fair value, except for investments in which the Company believes it has the ability to exercise significant influence (generally defined as investments in which the Company owns 20% or more of the outstanding voting common stock of the issuer), which are carried under the equity method of accounting. Under this method, the Company initially records an investment at cost, and then records its proportionate share of comprehensive income or loss for such investment after the date of acquisition.

The estimated fair value of investments in privately held securities, other than those carried under the equity method, is initially equal to the cost of such investments until the investments are revalued based principally on substantive events or other factors which could indicate a diminution or appreciation in value, such as an arm's-length third party transaction justifying an increased valuation or adverse development of a significant nature requiring a write down. The Company periodically reviews the valuation of investments in privately held securities with MMC Capital, Inc. ("MMC Capital"), its equity investment advisor.

Realized investment gains or losses on the sale of investments are determined by the first-in first-out method and recorded in net income. Unrealized appreciation or depreciation of securities which are carried at fair value is excluded from net income and recorded as a separate component of shareholders' equity, net of applicable deferred income tax.

F-11

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Net investment income, consisting of dividends and interest, net of investment expenses, is recognized when earned. The amortization of premium and accretion of discount for fixed maturity investments is computed utilizing the interest method. Anticipated prepayments and expected maturities are used in applying the interest method for certain investments such as mortgage and other asset-backed securities. When actual prepayments differ significantly from anticipated prepayments, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in the security is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the security. Such adjustments, if any, are included in net investment income.

CLAIMS AND CLAIMS EXPENSES

Prior to the sale of the Company's reinsurance operations, which is described in Note 2, the reserve for claims and claims expenses consisted of unpaid reported claims and claims expenses and estimates for claims incurred but not reported. These reserves were based on reports received from ceding companies, supplemented by the Company's estimates of reserves for which ceding company reports had not been received, and the Company's own historical experience. To the extent that the Company's own historical experience was inadequate for estimating reserves, such estimates were determined based upon industry experience and management's judgment. The ultimate liability may vary from such estimates, and any adjustments to such estimates were reflected in income in the period in which they became known. Reserves were recorded without consideration of potential salvage or subrogation recoveries which were estimated to be immaterial. Such recoveries, when realized, were reflected as a reduction of claims incurred.

FOREIGN EXCHANGE

Prior to the sale of the Company's reinsurance operations, the United States dollar was the functional currency for the Company's foreign business. Gains and losses on the translation into United States dollars of amounts that were denominated in foreign currencies are included in net income. Foreign currency revenue and expenses were translated at average exchange rates during the year. Unhedged monetary assets and liabilities denominated in foreign currencies were translated at the rate of exchange in effect at the balance sheet date.

INCOME TAXES

The Company utilizes the balance sheet method of accounting for income taxes. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. A valuation allowance is recorded if it is "more-likely-than-not" that some or all of a deferred tax asset may not be realized.

COMPREHENSIVE INCOME

In presenting its consolidated financial statements, the Company has adopted the reporting of comprehensive income in a one financial statement approach, consistent with Statement of Financial Accounting Standard ("SFAS") No. 130. Comprehensive income as shown below is comprised of net income and other comprehensive income, which for the Company consists of the change in net unrealized appreciation or depreciation of investments, net of tax.

EARNINGS PER SHARE DATA

Earnings per share are computed in accordance with SFAS No. 128, "Earnings per share" (see Note 13 for the Company's earnings per share computations). Basic earnings per share exclude dilution and is computed by dividing income available to common shareholders by the weighted average number of Common Shares outstanding for the periods. Diluted earnings per share reflect the potential dilution that could occur if Class A and B warrants and employee stock options were exercised for Common Shares. When a loss occurs, diluted per share amounts are computed using basic average shares outstanding because including dilutive securities would decrease the loss per share and would therefore be anti-dilutive.

SEGMENT INFORMATION

SFAS No. 131 requires certain disclosures about operating segments in a manner that is consistent with how management evaluates the performance of the segment.

Prior to the sale of the Company's reinsurance operations (see Note 2), the Company operated in one reportable business segment, which was providing property and casualty reinsurance and other forms of capital to insurance and reinsurance companies and making investments in insurance and insurance-related entities on a global basis. This segment included the results of Arch Re and Cross River, and consisted primarily of premiums, claims and claims expenses, other operating expenses and investment results.

Since the sale of the reinsurance operations, the Company, through its subsidiaries, has operated in one reportable business segment during 2000. The financial results of Hales, which was acquired during December 2000, was not material for the year ended December 31, 2000. See Note 12 for information concerning the Company's business.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

EMPLOYEE STOCK OPTIONS

The Company follows Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to Employees" ("APB No. 25") and related interpretations in accounting for its employee stock options because the alternative fair value accounting provided for under SFAS No. 123 "Accounting for Stock-Based Compensation" ("SFAS No. 123") requires use of option valuation models that were not developed for use in valuing employee stock options (see Note 9).

Under APB No. 25, no compensation expense is recognized by the Company because the exercise prices of the Company's employee stock options equal the market prices of the underlying stock on the date of grant. In addition, under APB No. 25, the Company does not recognize compensation expense for stock issued to employees under its stock purchase plan.

In March 2000, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation", an interpretation of APB No. 25 (the "Interpretation"). The Interpretation became effective July 1, 2000 and is to be applied prospectively (subject to certain exceptions) to all new awards, modifications to outstanding awards, and changes in employee status after that date. While there are certain exceptions to prospective application, the Company has adopted the Interpretation and its requirements are applied prospectively.

AMORTIZATION OF INTANGIBLE ASSETS

Goodwill of acquired businesses represents the difference between purchase cost and the fair value of the net assets of acquired businesses and is being amortized on a straight-line basis over the expected life of the related operations acquired which generally does not exceed 15 years. The Company evaluates the recoverability of the carrying value of goodwill related to acquired businesses on an undiscounted basis to ensure it is properly valued. If it is determined that an impairment exists, the excess of the unamortized balance will be charged to earnings at that time. See Note 2.

In connection with the Company's acquisitions of privately held equity securities recorded under the equity method of accounting, goodwill is amortized on a straight-line basis over 25 years (see Note 4).

FURNITURE, EQUIPMENT AND LEASEHOLD IMPROVEMENTS

The costs of furniture and equipment are charged against income over their estimated service lives. Leasehold improvements are amortized over the term of the office lease. Depreciation and amortization are computed on the straight-line method over a period of three to seven years. Maintenance and repairs are charged to expense as incurred.

Furniture, equipment and leasehold improvements, net of accumulated depreciation and amortization, at December 31, 2000 and 1999 recorded in other assets was $428,000 and $2,479,000, respectively.

RECLASSIFICATIONS

The Company has reclassified the presentation of certain prior year information to conform to the current presentation.

RECENT ACCOUNTING PRONOUNCEMENTS

DERIVATIVES AND HEDGING

In June 2000, the FASB issued SFAS No. 138 "Accounting for Certain Derivative Instruments and Certain Hedging Activities ("SFAS No. 138")." SFAS No. 138 amends SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS No. 133"), which was issued in June 1998, to address a limited number of SFAS No. 133 implementation issues.

F-14

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments imbedded in other contracts, and hedging activities, and requires that all derivative financial instruments be recognized in the balance sheet as either assets or liabilities and measured at fair value.

SFAS No. 133 is effective for fiscal years beginning after June 15, 2000, with initial application as of the beginning of the first quarter of the applicable fiscal year. The Company will adopt this statement in the first quarter of 2001. Generally, the Company has not invested in derivative financial instruments. However, derivatives may be embedded in other financial instruments, such as convertible securities and prepayment options in mortgages. If the embedded derivative meets certain criteria, it must be bifurcated from the host contract and separately accounted for consistent with other derivatives.

The Company's portfolio includes market sensitive instruments, such as convertible securities and mortgage-backed securities, which are subject to prepayment risk and changes in market value in connection with changes in interest rates. The Company's investments in mortgage-backed securities are classified as available for sale and are not held for trading purposes. Assuming the current investment strategy at the time of adoption, the Company's presentation of financial information under the new statement will not be materially different than the current presentation.

START-UP COSTS

Effective January 1, 1999, the Company changed its method of accounting for start-up costs in accordance with the Accounting Standards Executive Committee's Statement of Position ("SOP") 98-5 "Reporting on the Costs of Start-Up Activities." This statement requires costs of start-up activities, including organization costs, to be expensed as incurred.

The change in accounting principle resulted in the write-off of the start-up costs capitalized as of January 1, 1999 for the Company and its investee companies carried under the equity method of accounting.

The cumulative effect of the write-off, which totals $383,000, after-tax, or $0.02 per share, has been expensed and is included in the 1999 net loss.

4. INVESTMENT INFORMATION

At December 31, 2000, the Company's cash and investment portfolio totaled $279.1 million, consisting of approximately 13.8% in fixed maturity securities, 7.5% in securities held in escrow under the terms of the Folksamerica transaction (see Note 2), 18.4% in publicly traded equity securities, 21.3% in privately held securities, and 39% in cash and short-term investments. On May 5, 2000, the Company transferred $248.2 million of fixed maturities and short-term investments to Folksamerica in connection with the sale of the Company's reinsurance operations.

In addition, in connection with the Company's redomestication to Bermuda on November 8, 2000, it restructured its investment portfolio, and approximately $211 million of invested assets previously held by Arch Re were distributed to ACGL.

As of December 31, 2000, the Company recorded a pre-tax realized loss of $1.7 million that adjusted the cost basis of the Company's investments in IPC Holdings, Ltd. and Meadowbrook Insurance Group to a new cost basis that equaled their respective fair values and carrying values at December 31, 2000, which represented an "other than temporary" decline in their market values. Such write-downs resulted in a charge to net realized losses and a corresponding increase in the change in other comprehensive income. The Company classifies all of its publicly traded equity securities as "available for sale" and, accordingly, they are carried at estimated fair value (see Note 3). As long as the Company continues to hold these securities, their carrying values will be adjusted to reflect current market values.

4. INVESTMENT INFORMATION (CONTINUED)

The Company records its equity in the operating results of ARC on a two-month lag basis.

The Company has received cumulative distributions from ARC in the amount of $6.5 million, which have been recorded as reductions to the carrying value of the investment.

For the years ended 2000, 1999 and 1998, the Company's equity in net income, net of goodwill amortization and net of tax, was $1.1 million, or $0.08 per share, $827,000, or $0.05 per share, and $1.0 million, or $0.06 per share, respectively.

ARX HOLDING CORP.

In December 1997, the Company acquired a 35.2% economic and voting interest in Arx Holding Corp. ("ARX"), a Florida-based company, for $2,425,000. ARX, through its wholly owned subsidiary American Strategic Insurance Corp., underwrites homeowners policies in the State of Florida produced in the open market, and may also seek to offer other lines of insurance in Florida and other states.

Prior to the sale of the Company's reinsurance operations on May 5, 2000 (see Note 2), the Company provided reinsurance for ARX. A subsidiary of XL is a co-investor in ARX and provides reinsurance for ARX.

The Company's net premiums written and net premiums earned from business developed by ARX were $55,638 and $1.1 million, respectively, for the period January 1, 2000 through May 5, 2000, $8.2 million and $5.6 million, respectively, in 1999 and $2.8 million and $1.1 million, respectively, in 1998.

The Company records its equity in the operating results of ARX on a quarter-lag basis.

For the years ended 2000, 1999 and 1998, the Company's equity in net income
(loss), net of goodwill amortization and net of tax, was $467,000, $282,000 and ($63,000), respectively.

ISLAND HERITAGE INSURANCE COMPANY, LTD.

In 1996, the Company acquired a 33.4% economic interest (9.75% voting interest) in Island Heritage Insurance Company, Ltd. ("Island Heritage"), a Cayman Islands insurer, for an aggregate purchase price of $4.5 million, which was funded through $1.7 million in cash and a trust account in an amount equal to $2.8 million. Island Heritage commenced operations in May 1996 as an insurer which writes high value personal and commercial property insurance in the Caribbean. Certain directors of the Company and other investors invested in the securities of Island Heritage at the same per share price as that paid by the Company.

In February 1999, the Company made an additional investment in Island Heritage in the amount of approximately $1.0 million.

The investment in Island Heritage is recorded under the equity method of accounting since the Company believes it has the ability to exercise significant influence over the operating and financial policies of Island Heritage due to the Company's participation on the Board of Directors and through certain consent rights attaching to the Company's holdings of non-voting shares.

The Company records its equity in the operating results of Island Heritage on a quarter-lag basis.

Upon the Company's redomestication to Bermuda, Arch-U.S. distributed its investment in Island Heritage to ACGL, Arch-U.S.'s Bermuda parent. Prior to the distribution, the Company had recorded cumulative equity in net loss in Island Heritage of $1.1 million and a related deferred tax asset of $385,000. Since the cumulative equity in net loss recognized in financial income will not be deductible in future U.S. tax returns, the Company wrote-off the associated deferred tax asset during the 2000 fourth quarter. Since the distribution, the Company recorded equity in net income of Island Heritage of $65,000. Such income is included in foreign source income and is not subject to U.S. income tax. See Note 10.

For the year ended 2000, the Company's equity in net income was $178,000 on a pre-tax basis and, after recording the deferred tax asset write-off, the Company's after-tax equity in net loss was $235,000 or $0.02 per share.

In 1997, the Company acquired shares and warrants representing a 23.9% economic interest (9.9% voting interest) in LARC Holdings, Ltd. ("LARC"), a newly formed holding company located in Bermuda, for $24.5 million. LARC, through its wholly owned Bermuda subsidiary, Latin American Reinsurance Company, Ltd. ("LARe"), provides multi-line reinsurance to the Latin American reinsurance market, emphasizing short-tail, multi-peril property reinsurance and, to a limited extent, casualty, marine, aviation and other lines of reinsurance.

The Company co-invested with a subsidiary of XL, which holds a majority interest in LARC, and the founders of LARC.

The investment in LARC was recorded under the equity method of accounting since the Company believed it had the ability to exercise significant influence over the operating and financial policies of LARC due to the Company's participation on the Board of Directors and through certain consent rights attaching to the Company's holdings of non-voting shares.

The Company recorded its equity in the operating results of LARC on a quarter-lag basis.

On March 2, 2000, in connection with the Company's repurchase from XL of the Common Shares it previously held, the Company transferred to XL the Company's interest in LARC, valued at $25 million, and recognized a net book value gain of $300,000. See Note 13.

For the year ended 1999, the Company's equity in net loss, net of goodwill amortization and net of tax, was $113,750, and for the year ended 1998 the Company's equity in net income, net of goodwill amortization and net of tax was $531,700.

NEW EUROPE INSURANCE VENTURES

In 1997, the Company, through a wholly owned special purpose subsidiary, committed to pay $5 million over the long term to fund its partnership interest, currently at 14.6%, in New Europe Insurance Ventures ("NEIV"), a Scottish limited partnership that targets private equity investments in insurance and insurance-related companies in Eastern Europe.

The Company records its participation in this partnership under the equity method of accounting and applies the specialized accounting practices for investment companies. Unrealized gains and losses on private equity investments, consisting mostly of foreign exchange fluctuations, are recorded in the income statement when such investments are revalued into United States dollars each quarter.

During June 2000, the partners of NEIV determined to attempt to sell NEIV's current investment holdings, and that further investments in existing portfolio companies may be made but only on an exception basis and as part of a clear exit strategy.

The $642,000 investment balance at December 31, 2000 is composed of five investments in Eastern Europe in insurance related companies. The Company's unfunded commitment remaining at December 31, 2000 was approximately $3.2 million.

The Company records its equity in the operating results of NEIV on a quarter-lag basis. For the years ended 2000, 1999 and 1998, the Company's equity in net loss, net of tax, was $127,200, $345,150 and $141,700, respectively.

Sunshine State and its subsidiaries, which includes Sunshine State Insurance Company, a Florida domiciled insurer, underwrite homeowners policies in the State of Florida obtained from the Florida Residential Property and Casualty Joint Underwriting Association in accordance with the Market Challenge Program of the Florida Department of Insurance. Sunshine State also insures homeowners policies produced through the open market and offers other lines of insurance in Florida and other states. In connection with the investment, the Company provided reinsurance for Sunshine State prior to the sale of the Company's reinsurance operations on May 5, 2000 (see Note 2). A subsidiary of XL invested in Sunshine State and provides reinsurance for Sunshine State.

The Company records its equity in the operating results of Sunshine State on a quarter-lag basis.

For the years ended 2000, 1999 and 1998, the Company's equity in net income, net of tax, was $109,000, $179,000 and $171,600, respectively.

INVESTMENTS CARRIED AT FAIR VALUE:

ALTUS HOLDINGS, LTD.

In 1998, the Company purchased for $10 million an approximately 28.6% economic interest (9.9% voting interest) in Altus Holdings, Ltd. ("Altus"), a new Cayman Islands company formed to provide rent-a-captive and other underwriting management services for risks of individual corporations and insurance programs developed by insurance intermediaries. The Company's investment was funded two-thirds in cash and one-third through a letter of credit. The balance of the $35 million of initial capital invested in Altus was contributed by The Trident Partnership, L.P. ("Trident"), XL, MMRCH and members of Altus' management. During 1998, the Company issued a letter of credit in the amount of $5.8 million for Trident's unfunded investment commitment in Altus for an annual fee of $58,000, or 100 basis points on the letter of credit amount.

In May 1999, Altus acquired First American Financial Corporation ("First American") in a share exchange, which closed in July 1999 upon receipt of regulatory approval. First American, a Missouri-based company, through its wholly owned subsidiaries including First American Insurance Company, underwrites specialty vehicle property and casualty insurance coverages with emphasis placed on collateral protection. The Company had a 35.5% voting and economic interest in First American prior to its acquisition by Altus.

During the 1999 second quarter, the Company reclassified its investment in First American from the equity method of accounting to an investment accounted for at fair value. At June 30, 1999, the carrying value of First American was adjusted to $9.3 million in order to reflect the transaction value due to the acquisition by Altus, which resulted in the Company recording an after-tax realized loss of $0.7 million.

In July 1999, the Company and Trident funded their investment commitments to Altus (previously secured by letters of credit) of $3.3 million and $5.8 million, respectively, and XL redeemed its shares in Altus at their original cost. After Altus' acquisition of First American, such additional funding and the XL redemption, the Company's economic ownership in Altus decreased from 28.6% to 28% (9.9% voting interest). During 2000, pursuant to a purchase price adjustment relating to Altus' acquisition of First American, the Company's economic ownership in Altus decreased to 27.9%.

In the 2000 first quarter, the Company reduced the carrying value of Altus by $3.2 million, realizing an after-tax loss of $2.1 million. In reducing the carrying value of Altus, the Company, in consultation with its investment advisor, took into account the 1999 financial results of Altus and certain other factors, and based such write-down on a conservative valuation of Altus' economic book value at December 31, 1999.

F-22

4. INVESTMENT INFORMATION (CONTINUED)

Upon the Company's redomestication to Bermuda, Arch-U.S. distributed its investment in Altus to ACGL, its Bermuda parent. Prior to the distribution, the Company recorded cumulative losses in Altus and First American of $4.3 million and a related deferred tax asset of $1.5 million. Since the cumulative loss recognized in financial income will not be deductible in future U.S. tax returns, the Company wrote-off the $1.5 million deferred tax asset during the 2000 fourth quarter. See Note 10.

On March 23, 2001, the Company entered into a definitive agreement to acquire all of the remaining ownership interests in Altus.

AMERICAN INDEPENDENT INSURANCE HOLDING COMPANY

In 1999, the Company loaned $5 million to American Independent Insurance Holding Company ("AIHC"). The promissory note was secured by a second priority pledge of the capital stock of AIHC and the assets of AIHC, and had a maturity date of January 2003. The Company accrued interest at rates per annum that approximated 6%, depending on the investment returns on proceeds of the loan which were invested by AIHC on the Company's behalf. Principal and interest repayments were subject to prior approval by the Pennsylvania Department of Insurance. In consideration for the loan, the Company was issued warrants granting the Company the right to acquire equity in AIHC.

In connection with this investment and the Company's prior $3.6 million loan commitment to AIHC (which commitment expired on December 31, 1998), the Company had the option to write an aggregate amount of premiums of at least approximately $375 million over the next seven to eight-year period, subject to the amount of business written by American Independent Insurance Company ("AIIC"). This option was transferred to Folksamerica in connection with the sale of the Company's reinsurance operations on May 5, 2000 (see Note 2). From inception through May 5, 2000, premiums written by the Company under these arrangements with AIHC and its insurance subsidiary, AIIC, totaled $123.7 million. The Company's net premiums written and net premiums earned from business developed by AIIC were $16.6 million and $9.5 million, respectively, for the period January 1, 2000 through May 5, 2000, $39.2 million and $43.7 million, respectively, in 1999 and $42 million and $36 million, respectively, in 1998.

On March 6, 2000, the Company provided an additional loan in the principal amount of $3.5 million to AIHC. The loan was secured by a second priority pledge of the capital stock of AIHC and assets of AIHC, and had a maturity date of September 6, 2001. The net proceeds of the loan were contributed to the surplus of AIHC's subsidiary, AIIC. In connection with the loan, the Company was issued warrants (in addition to the warrants issued to the Company in connection with a prior loan to AIHC) granting the Company the right to acquire equity in AIHC.

Aggregate interest income recorded for the years ended December 31, 2000 and 1999 for the Company's loans to AIHC was $471,000 and $148,000, respectively.

As of December 31, 2000, based on a comparison of the AIHC notes to bonds with similar characteristics, the Company has a $1.1 million pre-tax unrealized loss adjusting the aggregate carrying value of $8.5 million in loans made to AIHC. Approximately $350,000 of such unrealized loss was recorded in the 2000 first quarter and $750,000 was recorded in 1999.

On February 28, 2001, the Company completed a reorganization transaction pursuant to which the Company acquired all of the common stock of AIHC. In connection with the acquisition, the Company's outstanding loans to AIHC were contributed to AIHC's capital and the Company also returned certain warrants to purchase shares of AIHC. See Note 15--Subsequent Events.

5. AGREEMENTS WITH RELATED PARTIES

INVESTMENT ADVISORY AGREEMENTS

Effective July 1, 1999, the Company amended its investment advisory agreement with MMC Capital, which governs management of the Company's portfolio of public equity securities ("Public Portfolio") and a portion of its portfolio of privately held equity securities, primarily in issuers engaged in, or providing services to, the insurance and reinsurance business ("Private Portfolio"). MMC Capital is also an investment advisor to Trident, a dedicated insurance industry private equity fund organized by MMC Capital and other sponsors. MMC Capital's direct parent, MMRCH, owns 1,395,625 shares, or approximately 11% of the outstanding Common Shares, and Class A warrants and Class B warrants to purchase 905,397 and 1,770,601 Common Shares, respectively. At December 31, 2000, Trident owns 250,000 shares, or approximately 2%, of the outstanding Common Shares, and Class A warrants to purchase 1,386,079 Common Shares.

Pursuant to the amended agreement, which has a term of four years (subject to renewal or early termination under certain circumstances), MMC Capital provides the Company with investment management and advisory services with respect to investments in the Private Portfolio whose value exceeds (i) $10 million during the first year of the term, (ii) $15 million during the second year of the term, and (iii) $20 million during the third and fourth years of the term. Under such amendments, the Company pays MMC Capital an annual fee equal to (x) 20% (previously 7.5%) of cumulative net realized gains including dividends, interest and other distributions, received on the Private Portfolio over (y) cumulative compensation previously paid in prior years on cumulative net realized gains (as defined in the agreement) on the Private Portfolio managed by MMC Capital, but the Company will not pay MMC Capital a management fee (previously 1.5% per annum of the quarterly carrying value of the Private Portfolio). With respect to the management of the Company's Public Portfolio, the Company pays MMC Capital a fee equal to 0.50% of the first $50 million under MMC Capital's management and 0.35% of all amounts in excess of $50 million (subject to a minimum fee of $250,000 per annum). Fees incurred under the agreements during fiscal years 2000, 1999 and 1998 were approximately $298,000, $1.5 million and $2.7 million, respectively. In addition, in 1999 and 1998, unrealized appreciation in the Private Portfolio is net of accrued fees of approximately $256,000 and $2.2 million, respectively.

In connection with its amended investment advisory agreement with MMC Capital, the Company receives from MMC Capital $1.25 million per annum during the initial four-year term, subject to certain conditions.

In May 1999, the Company transferred the management of the fixed income and short-term cash portfolios from The Putnam Advisory Company, Inc. ("Putnam"), an affiliate of MMC Capital, to Alliance Capital. For the fixed income securities portfolio, the Company paid to Putnam a fee equal to the sum of 0.35% per annum of the first $50 million of the market value of the portfolio, 0.30% per annum on the next $50 million, 0.20% per annum on the next $100 million and 0.15% per annum of the market value of assets that exceeds $200 million. For the short-term cash portfolio, the Company paid a fee equal to 0.15% per annum of the total monthly average market value. Fees incurred under the Putnam agreement for the period in 1999 and 1998 were approximately $173,000 and $461,000, respectively.

REINSURANCE TREATIES

Prior to the sale of the Company's reinsurance operations on May 5, 2000 (see Note 2), in addition to business assumed from insurance companies where the Company had a private equity investment as described in Note 4, the Company also assumed premiums written and premiums earned of $1.6 million and $1.9 million, respectively, for the period January 1, 2000 through May 5, 2000, $5.2 million and $5.3 million, respectively, in 1999, and $3.3 million and $3.4 million, respectively, in 1998 from XL, which owned 4,755,000 Common Shares prior to the share repurchase described in Note 13, or approximately 27.8% of the outstanding Common Shares, and premiums written and premiums earned of $4.9 million and $4.9 million, respectively, for the period January 1, 2000 through May 5, 2000, $17.4 million and $17.3 million, respectively, in 1999 and $18.5 million and $20.7 million, respectively, in 1998 from insurance companies majority-owned by Trident.

OTHER TRANSACTIONS

Commencing in 1996, MMC Capital subleased office space from the Company for a term expiring in October 2002. Future minimum rental income, exclusive of escalation clauses and maintenance costs, under the remaining term of the sublease will be approximately $1,891,000. Rental income for 2000 was $636,000 and $430,000 in each of 1999 and 1998.

In addition, in 1999 and 1998, MMC Capital reimbursed the Company approximately $1,000 and $11,000 (net of $59,000 and $89,000 for certain sublease income allocated to MMC Capital) for their pro-rata share of improvement and maintenance costs under the sublease.

During 1999, the Company committed to invest $25 million as a limited partner in Trident II, a partnership managed by MMC Capital, and, during 2000, the Company committed to invest $1.2 million as a member of the general partner of a fund affiliated with Hales. See Note 4.

On March 2, 2000, the Company repurchased from XL Capital, then its single largest shareholder, all of the Common Shares held by XL Capital in a transaction described in Note 13.

Prior to sale of the Company's reinsurance operations on May 5, 2000, affiliates of MMC Capital's ultimate parent, Marsh & McLennan Companies, Inc. ("Marsh"), acted as reinsurance intermediaries to Arch Re as indicated in Note
12. The Company has also utilized affiliates of Marsh as insurance brokers for the Company's insurance needs.

In addition, the Company has made investments in entities in which affiliates of Marsh, Trident and XL Capital have invested. See Note 4.

6. COMMITMENTS (CONTINUED)

All of these leases are for the rental of office space, with expiration terms that range from 2001 to 2009. During 2000, 1999 and 1998, rental expense, net of income from subleases, was approximately $190,000, $576,000 and $576,000, respectively.

EMPLOYMENT AGREEMENTS AND SEVERANCE ARRANGEMENTS

Under the terms of employment with its executive officers, the Company or such officers may terminate their employment at any time. Such employment arrangements provide for compensation in the form of base salary, annual bonus, stock-based awards, participation in the Company's employee benefit programs and the reimbursements of expenses.

The sale of the Company's reinsurance operations on May 5, 2000 constituted a change in control for purposes of the change in control and other benefit and employment arrangements that existed on such date. Under these arrangements, all unvested stock options and shares of restricted stock held by employees and the members of the board of directors (other than the Chairman of the Board) vested in connection with the asset sale. See Note 2.

Following the asset sale, the Company has a program for certain executives that provides for certain severance payments, immediate vesting of restricted stock grants and option awards and continuation of benefits in the event of termination of employment resulting from a change in control. The extent of such payments depends on the position of the executive.

The Company believes that its exposure, if any, to environmental impairment liability and asbestos-related claims was minimal since no business had been written for periods prior to 1996.

Subject to the following, the Company believes that the reserves for claims and claims expenses were adequate to cover the ultimate cost of claims and claims expenses incurred through the sale of its reinsurance operations on May 5, 2000 (see Note 2). The reserves were based on estimates of claims and claims expenses incurred. The inherent uncertainties of estimating claims and claims expense reserves are exacerbated for

F-28

7. CLAIMS AND CLAIMS EXPENSES (CONTINUED)

reinsurers by the significant periods of time (the "tail") that often elapse between the occurrence of an insured claim, the reporting of the claim to the primary insurer and, ultimately, to the reinsurer, and the primary insurer's payment of that claim and subsequent indemnification by the reinsurer. As a consequence, actual claims and claims expenses paid may deviate, perhaps materially, from estimates reflected in the Company's reserves reported in its financial statements. The estimation of reserves by new reinsurers, such as the Company prior to the asset sale, may be less reliable than the reserve estimations of a reinsurer with an established volume of business and claims history.

Estimates of prior accident year claims were increased by approximately $3 million in 2000 primarily due to aviation and property business.

Estimates of prior accident year claims were increased by approximately $30 million in 1999. A substantial portion of this amount resulted from (i) the Company's review of additional claims information and actuarial analysis of the business produced by a certain managing underwriting agency, (ii) notification of additional satellite losses received in 1999 pertaining to 1998, (iii) aviation losses, principally the 1998 Swiss Air crash, and (iv) property losses reported on several international treaties that were in run-off in 1999.

Estimates of prior accident year claims were reduced by approximately $2.8 million in 1998 primarily due to favorable claim development in the property and multi-line classes of business.

8. RETROCESSION AGREEMENTS

Prior to the sale of the Company's reinsurance operations on May 5, 2000 (see Note 2), the Company utilized retrocession agreements for the purpose of limiting its exposure with respect to multiple claims arising from a single occurrence or event. The Company also participated in "common account" retrocessional arrangements for certain treaties. Such arrangements reduced the effect of individual or aggregate losses to all companies participating on such treaties including the reinsurer, such as the Company, and the ceding company.

Reinsurance recoverables are recorded as assets, predicated on the retrocessionaires' ability to meet their obligations under the retrocessional agreements. If the retrocessionaires were unable to satisfy their obligations under the agreements, the Company would have been liable for such defaulted amounts.

With respect to the Company's divested reinsurance operations, the effects of reinsurance on written and earned premiums and claims and claims expenses are as follows:

1995 LONG TERM INCENTIVE AND SHARE AWARD PLAN

In September 1995, the Company adopted the 1995 Long Term Incentive and Share Award Plan (the "1995 Stock Plan"), which is administered by the Company's Board of Directors and its Stock Awards Committee. The Company may grant, subject to certain restrictions, stock options, stock appreciation rights, restricted shares, restricted share units payable in Common Shares or cash, stock awards in lieu of cash awards, and other stock-based awards to eligible employees and directors of the Company. Awards relating to not more than 1,700,000 Common Shares may be made over the ten-year term of the 1995 Stock Plan.

In April 1999, the Company adopted the 1999 Long Term Incentive and Share Award Plan (the "1999 Stock Plan"). The 1999 Stock Plan, like its predecessor, is intended to provide incentives to attract, retain and motivate employees and directors in order to achieve the Company's long-term growth and profitability objectives. The 1999 Stock Plan provides for the grant to eligible employees and directors of stock options, stock appreciation rights, restricted shares, restricted share units payable in Common Shares or cash, stock awards in lieu of cash awards, dividend equivalents and other stock based awards. The 1999 Stock Plan also provides the non-employee directors with the opportunity to receive the annual Board retainer fee in Common Shares. An aggregate of 900,000 Common Shares has been reserved for issuance under the 1999 Stock Plan (of which no more than 300,000 of such shares may be issued pursuant to grants of restricted shares, restricted share units, performance shares and performance units), subject to anti-dilution adjustments in the event of certain changes in the Company's capital structure. Shares issued pursuant to the 1999 Stock Plan are either authorized but unissued shares or treasury shares.

RESTRICTED COMMON SHARES

During 2000, 1999 and 1998, the Company granted an aggregate of 74,218, 2,500 and 15,700 shares, respectively, of restricted shares under the 1995 Stock Plan. A grant of 50,000 restricted shares to one executive officer vests at a rate of one-third per year commencing January 1, 2001, and the balance of restricted shares granted during 2000 fully vest on January 1, 2001. The Company records a deferred expense equal to the market value of the shares at the date of grant which is amortized and charged to income over the vesting period. The deferred expense was $1,122,000, ($117,000) and $296,000, and the amortization of the deferred expense was $1,098,000, $628,000 and $1,012,000, for 2000, 1999 and 1998, respectively. Upon the sale of the Company's reinsurance operations on May 5, 2000, all outstanding unvested restricted shares vested.

STOCK OPTIONS

The Company issues incentive stock options and non-qualified stock options to officers and directors, with exercise prices equal to the fair market values of the Company's common shares on the grant dates. Options to officers generally vest and become exercisable at a rate of 25% per year over four years from the grant date and expire ten years after the grant date. Initial options granted to non-employee directors vest and become exercisable in three equal installments, commencing on the grant date and annually thereafter. Annual options granted to non-employee directors in office on January 1 of each year vest on the first anniversary of the grant date. Upon the sale of the Company's reinsurance operations on May 5, 2000, substantially all outstanding unvested stock options vested.

Information relating to the Company's stock options is set forth below:

Exercise prices for options outstanding at December 31, 2000 ranged from $12.66 to $22.13. The weighted-average remaining contractual life of these options is approximately six years.

EMPLOYEE STOCK PURCHASE PLAN

Effective December 1, 1995, the Company established a tax-qualified employee stock purchase plan (the "Purchase Plan"). An aggregate of 120,000 Common Shares have been reserved for issuance under the Purchase Plan. Eligible employees may elect to participate in an annual offering period under the Purchase Plan by authorizing after-tax payroll deductions of up to 20% (in whole percentages) of their eligible compensation for the purchase of Common Shares at 85% of the lesser of the per share market value of the Common Shares at the beginning or end of the annual offering period, subject to certain restrictions. During 2000, 1999 and 1998, employees purchased approximately 10,179, 8,509 and 18,638 Common Shares, respectively, under the Purchase Plan.

PRO FORMA INFORMATION

As provided under SFAS No. 123, "Accounting for Stock-Based Compensation," the Company has elected to continue to account for stock-based compensation in accordance with APB No. 25 and has provided the required additional pro forma disclosures. Such information has been determined for the Company as if the Company had accounted for its employee stock options under the fair value method of this statement. The fair value for the Company's employee stock options has been estimated at the date of grant using a Black-Scholes option valuation model, with the following weighted-average assumptions for options issued in 2000, 1999 and 1998, respectively: dividend yield of 0.0% for 2000, 1999 and 1998; expected volatility of 32.0% in 2000, 25.0% in 1999 and 1998; risk free interest rate of 5.0% in 2000, 6.5% in 1999 and 4.9% in 1998; and an average

9. EMPLOYEE BENEFITS AND COMPENSATION ARRANGEMENTS (CONTINUED)

expected option life of six years for 2000, 1999 and 1998. The weighted-average fair value of options granted during the years ended December 31, 2000, 1999 and 1998 was $866,000, $123,000 and $3.3 million, respectively.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models, such as the Black-Scholes model, require the input of highly subjective assumptions (particularly with respect to the Company, which has a limited stock-trading history), including expected stock price volatility. As the Company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the Company believes that the existing option valuation models, such as the Black-Scholes model, may not necessarily provide a reliable single measure of the fair value of employee stock options.

For purposes of the required pro forma information, the estimated fair value of employee stock options is amortized to expense over the options' vesting period. The Company's net income (loss) and net income (loss) per share would have been adjusted to the pro forma amounts indicated below:

                                                       (IN THOUSANDS, EXCEPT PER SHARE DATA)

The effects of applying SFAS No. 123 as shown in the pro forma disclosures may not be representative of the effects on reported net income for future years.

The effect on net income and earnings per share after applying SFAS No. 123's fair valuation method to stock issued to employees under the Purchase Plan does not materially differ from the pro forma information set forth above with respect to the Company's employee stock options.

RETIREMENT PLANS

Effective as of January 1, 1996, the Company adopted a tax-qualified, non-contributory defined contribution money purchase pension plan (the "Pension Plan") under which the Company contributes for each eligible employee an amount equal to the sum of (i) 5% in 2000 and 1999 and 4% in 1998 of eligible compensation up to the taxable wage base (for 2000, 1999 and 1998, the amount was set at $76,400, $72,600 and $68,400, respectively) and (ii) 10% in 2000 and 1999 and 8% in 1998 of eligible compensation in excess of the taxable wage base up to the applicable compensation limit (the "compensation limit") imposed by
Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (the "Code"), which for 2000, 1999 and 1998 was $160,000. Substantially all employees of the Company are eligible for participation in the Pension Plan. In 2000, 1999 and 1998, the Company expensed $180,000, $344,000 and $215,000, respectively, related to the Pension Plan.

Effective as of January 1, 1996, the Company adopted a tax-qualified, employee savings plan (the "Savings Plan"). Pursuant to Section 401(k) of the Code, eligible employees of the Company are able to make deferral contributions of up to 15% of their eligible compensation, subject to limitations under applicable law. The Company matches 100% of the first 3% of eligible compensation deferred by employees and 50% of the next 3% of eligible compensation so deferred. Substantially all employees of the Company are eligible for

participation in the Savings Plan. In 2000, 1999 and 1998, the Company expensed $111,000, $192,000 and $165,000, respectively, related to the Savings Plan.

Effective as of January 1, 1996, the Company adopted a supplemental, non-qualified executive savings and retirement plan (the "Supplemental Plan") under which the Company contributes 10% of eligible compensation in excess of the compensation limit for eligible officers of the Company. Participants may also defer certain amounts of eligible base compensation and bonus. Under the Supplemental Plan, the Company matches 100% of the first 3% of eligible base compensation in excess of the compensation limit that is deferred by participants under the Supplemental Plan, and provides a 50% matching contribution for the next 3% of such excess eligible compensation so deferred. In 2000, 1999 and 1998, the Company expensed $30,000, $96,000 and $85,000, respectively, related to the Supplemental Plan.

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 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. payors. 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 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 adversely affected. ACGL's U.S. subsidiaries will continue to be subject to U.S. income taxes on their worldwide income.

The U.S. subsidiaries of ACGL, Arch-U.S., Hales, Arch Re and Cross River, file a consolidated federal income tax return and have a tax sharing agreement (the "Tax Sharing Agreement"), allocating the consolidated income tax liability on a separate return basis. Pursuant to the Tax Sharing Agreement, Hales, Arch Re and Cross River make tax sharing payments to Arch-U.S. based on such allocation.

The provision for federal income taxes has been determined on the basis of a consolidated income tax return consisting of Arch-U.S., Hales, Arch Re and Cross River.

Pre-tax income (loss) from operations was taxed under the following jurisdictions for the years ended December 31, 2000, 1999 and 1998 as follows:

In 1999 and 1998, the Company's effective income tax rate for equity in net income (loss) of investees equaled the federal statutory income tax rate of 35%. The Company had no current federal tax expense or benefit for the year ended December 31, 2000 due to its net operating losses and the full utilization of the two year carry-back provision at December 31, 1999. During 2000, the Company recovered $8.6 million of previously paid income taxes. Actual federal income taxes paid in 1999 and 1998 were $1.9 million and $5.3 million, respectively. The amount paid in 1999 was the final installment related to the 1998 tax return.

10. INCOME TAXES (CONTINUED)

As a result of the Company's net operating losses in 2000 and 1999, the Company has net operating loss carryforwards totaling $35.6 million at December 31, 2000. Such net operating losses are currently available to offset future taxable income of the Company with the following expiration dates: $18.3 million expiring in 2019 and $17.3 million expiring in 2020. The Company also has an alternative minimum tax ("AMT") credit carryforward in the amount of $651,000 which can be carried forward without expiration.

The repurchase of the Common Shares held by XL Capital resulted in a 27.8% change in ownership by 5% shareholders. If, in the ensuing three years, there is more than a 22.2% additional change in ownership by 5% shareholders, an "ownership change" will have taken place for federal income tax purposes. If such ownership change occurs, the amount of loss carryforwards that can be used in any subsequent year may be severely limited and could be eliminated in certain circumstances. See Note 13.

Upon the Company's redomestication to Bermuda, Arch-U.S. distributed substantially all of its public equity portfolio to ACGL, its Bermuda parent, at the current market values and realized gains for tax purposes of $21,044,000. The associated income tax expense of $7,365,000 reduced the Company's net operating loss carryforwards by such amount. However, for financial reporting purposes, since the securities have not been sold to an unrelated third party, the realized gain has been deferred and is reported as unrealized appreciation in the consolidated financial statements. Accordingly, in the consolidated financial statements the income tax expense is also deferred and reduces unrealized appreciation. In addition, the Company has written off $2.0 million of deferred tax assets relating to losses recognized in financial income on the Company's investments in Island Heritage and Altus, which will not be deductible in future U.S. income tax returns since Arch-U.S. distributed these investments to ACGL, its Bermuda parent. See Note 4.

The net deferred income tax asset reflects temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes, net of a valuation allowance for any portion of the deferred tax asset that management believes will not be realized. Significant components of the Company's deferred income tax assets and liabilities as of December 31, 2000 and 1999 were:

As of December 31, 2000, the Company has a valuation allowance of $5.7 million that adjusts the net deferred income tax asset to its estimated realizable value of $8.2 million. Such deferred income tax asset is net

of a deferred income tax liability of $178,000. Deferred income tax expense for the year ended December 31, 2000 included a charge for such allowance of $5.7 million.

At December 31, 1999, the Company did not have a deferred income tax valuation allowance because it believed at that time that its entire deferred tax asset was realizable due to the Company's ability to generate future taxable income from its invested asset base of $576.5 million. At that time, the closing of the Folksamerica transaction was uncertain and, consequently, the tax implications of the transaction were not considered in evaluating the realizability of the deferred tax asset. On May 5, 2000, the Company sold the reinsurance operations of Arch Re to Folksamerica. The asset sale generated a tax loss of $30 million (excluding unrealized loss on fixed maturities, of which $5.3 million was realized upon the related transfer of assets to Folksamerica). See Note 2. The transfer of assets to Folksamerica at closing also resulted in a significant reduction in the Company's invested assets and its ability to generate future taxable income. In addition, upon the completion of the Company's redomestication to Bermuda, the Company restructured its investment portfolio and distributed approximately $211 million of invested assets to ACGL, which further reduced Arch-U.S.'s invested assets available to generate investment income.

11. STATUTORY INFORMATION

The Insurance Department of the State of Nebraska issued to Arch Re its domiciliary insurance license on November 6, 1995. Statutory net income and surplus of Arch Re, as reported to insurance regulatory authorities, differ in certain respects from the amounts prepared in accordance with GAAP. The primary differences between statutory net income and GAAP net income relate to deferred acquisition costs, deferred income taxes and accounting for the Company's private equity investments. The main differences between statutory surplus and shareholder's equity arise from unrealized appreciation or depreciation on investments and non-admitted assets, as well as deferred income taxes. The following table shows statutory net income (loss) compared to GAAP net income
(loss), and statutory surplus compared to shareholder's equity of Arch Re:

Prior to the Company's redomestication to Bermuda on November 8, 2000 (see Note 1), the Company did not have any significant assets other than its ownership of the capital stock of Arch Re. Accordingly, the Company relied on the cash dividends and distributions from Arch Re to make payments, including for any operating expenses. Arch Re's ability to pay dividends or make distributions is dependent upon its ability to meet the applicable regulatory standards of the State of Nebraska, which require, among other things, that Arch Re obtain the prior approval of the Nebraska Director of Insurance (the "Nebraska Director") before paying dividends or making distributions in certain circumstances as described below.

Following the approval of the Nebraska Director, in connection with the Company's share repurchase from XL on March 2, 2000 as described in Note 13, Arch Re's statutory surplus was reduced by $62.8 million due to the distribution to Arch-U.S. of the stock and warrants in both LARC Holdings, Ltd. and Annuity and Life Re Holdings, Ltd.

11. STATUTORY INFORMATION (CONTINUED)

In connection with the November 8, 2000 reorganization, and following the approval of the Nebraska Director, Cross River and Arch Re completed an equal exchange of approximately $13.6 million of assets, and Cross River made a distribution to Arch Re of approximately $2.1 million. Following such transactions, and following the approval of the Nebraska Director, Arch Re distributed net assets of $228.4 million to Arch-U.S., of which $211 million was distributed to ACGL during the 2000 fourth quarter. As of December 31, 2000, after reflecting the distribution of assets in connection with the XL share repurchase and the reorganization, Arch Re had statutory surplus of $29.8 million.

Nebraska insurance laws provide that, without prior approval of the Nebraska Director, Arch Re cannot pay a dividend or make a distribution (together with other dividends or distributions paid during the preceding 12 months) that exceeds the greater of (i) 10% of statutory surplus as of the preceding December
31 ($29.9 million as of December 31, 2000) or (ii) statutory net income from operations from the preceding calendar year not including after-tax realized capital gains ($24.1 million income for 2000). Net income (exclusive of realized capital gains) not previously distributed or paid as dividends from the preceding two calendar years may be carried forward for dividend and distribution purposes. Any proposed dividend or distribution in excess of such amount is called an "extraordinary" dividend or distribution and may not be paid until either it has been approved, or a 30-day waiting period has passed during which it has not been disapproved, by the Nebraska Director. Notwithstanding the foregoing, Nebraska insurance laws provide that any distribution that is a dividend may only be paid out of earned surplus arising from its business, which is defined as unassigned funds (surplus) as reported in the statutory statement for the most recent year, not including any surplus arising from unrealized capital gains or revaluations of assets ($7.0 million deficit as of December 31, 2000). Any distribution that is a dividend and that is in excess of Arch Re's unassigned funds, exclusive of any surplus arising from unrealized capital gains or revaluation of assets ($9.6 million deficit as of December 31, 2000), will be deemed an "extraordinary" dividend subject to the foregoing requirements. Therefore, Arch Re cannot make a distribution that is a dividend without the prior approval of the Nebraska Director during 2001. In addition, due to the above-described distributions that were made in connection with the XL Capital share repurchase and the Company's reorganization, Arch Re may not declare any other distribution for 12 months from December 1, 2000 unless such subsequent distribution is approved by the Nebraska Director.

Nebraska insurance laws also require that the statutory surplus of Arch Re following any dividend or distribution be reasonable in relation to its outstanding liabilities and adequate to its financial needs. In addition, Nebraska insurance laws require that each insurer give notice to the Nebraska Director of all dividends and other distributions within five business days following declaration thereof and that any such dividend or other distribution may not be paid within ten business days of such notice (the "Notice Period") unless for good cause shown the Nebraska Director has approved such payment within the Notice Period.

The Company files statutory-basis financial statements with state insurance departments in all states in which the Company is licensed. On January 1, 2001, significant changes to the statutory basis of accounting will become effective. The cumulative effect of these changes, known as the Codification guidance, will be recorded as a direct adjustment to statutory surplus. The effect of adoption will be a net decrease in surplus of Cross River on a stand-alone basis in the amount of $248,000 (unaudited), primarily as a result of the recording of a deferred tax liability. The Company currently estimates that there will be no effect on Arch Re's surplus as a result of the adoption of such codification.

12. BUSINESS INFORMATION

As discussed in Note 3, prior to the sale of the Company's reinsurance operations, the Company operated in one reportable business segment, which was providing property and casualty reinsurance and other forms of capital to insurance and reinsurance companies and making investments in insurance and insurance-related entities on a global basis. This segment included the results of Arch Re and Cross River, and consisted primarily of premiums, claims and claims expenses, other operating expenses and investment results.

12. BUSINESS INFORMATION (CONTINUED)

Since the sale of the reinsurance operations, the Company, through its subsidiaries, has operated in one reportable business segment during 2000. The financial results of Hales, which was acquired during December 2000, were not material for the year ended December 31, 2000.

The Company's principal offices are in Hamilton, Bermuda and its executive offices are in Greenwich, Connecticut.

With respect to the Company's divested reinsurance operations, the data discussed below is not meaningful for the period January 1, 2000 through May 5, 2000. During 1999, one client contributed $42.1 million, or 13.7%, of net premiums written and $33.8 million, or 13.5%, of net premiums earned, and a second client contributed $39.2 million, or 12.8%, of net premiums written and $43.7 million, or 14%, of net premiums earned. For 1998, that second client company contributed approximately $42 million, or 18%, of net premiums written and $36.6 million, or 17.8%, of net premiums earned. The following lists individual broker business greater than 10% of the 1999 year's net premiums written with comparative amounts for the year ended 1998:

13. SHARE CAPITAL

As part of the reorganization described in Note 1, 4,790,415 treasury shares were cancelled. The authorized share capital of the Company consists of 200,000,000 common shares, par value U.S. $0.01 per share, and 50,000,000 preference shares, par value U.S. $0.01 per share. Prior to the reorganization, the authorized share capital of Arch-U.S. consisted of 80,000,000 shares of common stock, par value U.S. $0.01 per share, and 20,000,000 shares of preferred stock, par value U.S. $0.01 per share.

The bye-laws of ACGL contain a provision limiting the voting rights of any person who owns (directly, indirectly or constructively under the United States Internal Revenue Code) Common Shares with more than 9.9% of the total voting power of all shares entitled to vote generally at an election of directors to 9.9% of such voting power. This provision will not restrict the ability of any person holding Common Shares that were either (1) converted from shares of Arch-U.S. owned on September 8, 2000 or (2) issued upon exercise of warrants owned by such person on September 8, 2000 which were assumed by ACGL, from voting such shares except with respect to the election of directors. This provision is intended to prevent ACGL from being characterized

as a controlled foreign corporation which could cause U.S. persons owning 10% or more of the Common Shares to suffer adverse U.S. tax consequences.

The bye-laws of ACGL also contain a provision limiting the rights of any group (within the meaning of the United States Securities Exchange Act of 1934) that owns shares with more than 9.9% of the total voting power of all shares entitled to vote generally at an election of directors to 9.9% of such voting power. This provision will not restrict (a) the ability of any such group holding Common Shares that were converted from shares of Arch-U.S. by such person on September 8, 2000 or acquired upon exercise of warrants owned by such person on September 8, 2000 which were assumed by ACGL or (b) any person or group that the board of directors, by the affirmative vote of at least 75% of the existing board, may exempt from this provision, from voting such shares.

On March 2, 2000, the Company repurchased from XL Capital, then the Company's single largest shareholder, all of the 4,755,000 Common Shares held by it for a purchase price of $12.45 per share, or a total of $59.2 million. The per share repurchase price was determined as the lesser of (1) 85% of the average closing market price of the Common Shares during the 20 trading days beginning on the third business day following public announcement of the share repurchase and asset sale (January 21, 2000), which was $14.65, and (2) $15. The Company paid XL the consideration for the repurchase with: (i) the Company's interest in privately held LARC Holdings, Ltd. (parent of Latin American Reinsurance Company Ltd.), valued at $25 million, and (ii) all of the Company's interest in Annuity and Life Re (Holdings), Ltd., valued at $25.38 per share and $18.50 per warrant, or $37.8 million in the aggregate. XL paid the Company in cash the difference (equal to $3.6 million) between the repurchase price and the value of the Company's interests in LARC Holdings and Annuity and Life Re. The value per share of Annuity and Life Re was determined by taking the average of the closing price of Annuity and Life Re shares for the same period used in determining the repurchase price of the Common Shares. The value of the warrants was determined using a Black Scholes methodology.

The cost of the share repurchase of $59.2 million was recorded as a reduction to shareholders' equity reflected as treasury shares, which shares were subsequently cancelled.

In addition, warrants to purchase 4,451,680 Common Shares at $20 per share were outstanding as of December 31, 2000, 1999 and 1998 but were not included in the computation of diluted earnings per share for the year ended December 31, 2000 and 1999 because the warrants' exercise price of $20.00 per share was greater than the average market price of the Common Shares for such year. Diluted per share amounts are computed using basic average shares outstanding when a loss occurs since the inclusion of dilutive securities in dilutive earnings per share would be anti-dilutive.

For the 2000 fourth quarter, the Company reported comprehensive income of $2.2 million, which was composed of net loss of $14.3 million and other comprehensive income of $16.5 million, consisting of the change in after-tax unrealized appreciation of investments. The 2000 fourth quarter net loss primarily consisted of investment losses realized upon restructuring the Company's investment portfolio in connection with its redomestication to Bermuda (see Note 4) and the establishment of a contingent reserve in connection with an escrow arrangement relating to the sale of the Company's reinsurance operations in May 2000 (see Note 2).

15. SUBSEQUENT EVENTS

AMERICAN INDEPENDENT INSURANCE HOLDING COMPANY

On February 28, 2001, the Company completed a reorganization transaction pursuant to which the Company acquired all of the common stock of one of its current investee companies, AIHC. See Note 4.

The Company purchased a portion of the outstanding shares of AIHC for $1.25 million. The remaining outstanding shares of AIHC were redeemed by AIHC in exchange for the right to receive a portion of the proceeds resulting from the final adjudication or settlement of certain lawsuits that AIHC, as plaintiff, has previously filed against certain defendants. A third party also forgave the obligations owing to it under certain notes previously issued by AIHC in the aggregate principal amount of $4 million and returned certain warrants to purchase shares of AIHC in exchange for the right to receive a portion of the proceeds resulting from the final adjudication or settlement of such lawsuits. Immediately after the Company's purchase of AIHC, the Company contributed to the capital of AIHC notes in the aggregate principal amount of $8.5 million that were issued to the Company in connection with loans it had previously made to AIHC (see Note 4) and also returned certain

15. SUBSEQUENT EVENTS (CONTINUED)

warrants to purchase shares of AIHC. Following the purchase, the Company also made a capital contribution to AIHC in the amount of $11.0 million.

In connection with the loans the Company previously made to AIHC, the Company had obtained rights to provide reinsurance to American Independent for specified periods, which rights had been transferred to Folksamerica in the asset sale on May 5, 2000. In connection with the Company's acquisition of AIHC, Folksamerica released American Independent from these reinsurance commitments at a cost to American Independent of $1.5 million.

ALTUS HOLDINGS, LTD.

On March 23, 2001, the Company entered into a reorganization agreement for the acquisition of all of the remaining ownership interests in one of its current investee companies, Altus Holdings, Ltd. ("Altus"). Altus, a privately held company, provides insurance and alternative risk transfer services through rent-a-captive and other facilities. The Altus group includes First American Insurance Company, an admitted insurer with licenses in 49 states and an A.M. Best rating of A-. See Note 4.

Under the agreement, the Company will acquire Altus for a purchase price of approximately $36 million. The transaction is contingent on obtaining applicable regulatory approvals, expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, and other customary closing conditions.

ARCH CAPITAL GROUP LTD.

RESTRICTED SHARE AGREEMENT

THIS AGREEMENT, dated as of January 1, 2001, between Arch Capital Group Ltd. (the "Company"), a Bermuda corporation, and Robert Clements (the "Executive").

WHEREAS, the Company and the Executive have entered into a Retention and Change in Control Agreement, dated as of May 5, 2000 (the "Retention Agreement"), under which the Executive will receive compensation at an annual rate equal to one-half of the salary of the Company's President and Chief Executive as compensation for the Executive's services as Chairman of the Board of Directors; and the following terms reflect the Company's 1995 Long Term Incentive and Share Award Plan (as amended, the "Plan");

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein, the parties hereto agree as follows:

1. AWARD OF SHARES. Pursuant to the provisions of the Plan, the terms of which are incorporated herein by reference, the Executive is hereby awarded 12,500 Restricted Shares (the "Award"), subject to the terms and conditions herein set forth. Capitalized terms used herein and not defined shall have the meanings set forth in the Plan.

2. TERMS AND CONDITIONS. It is understood and agreed that the Award of Restricted Shares evidenced hereby is subject to the following terms and conditions:

(a) VESTING OF AWARD. Subject to the other terms and conditions of this Agreement, this Award shall become vested in full on January 1, 2002; provided that all such shares shall immediately become vested (i) to the extent provided in Section 2(b) hereof and (ii) upon a Change in Control.

"Change in Control" means any of the following occurring after the date hereof:

a. any person (within the meaning of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), other than a Permitted Person or an Initial Investor, is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of Voting Securities representing 35% or more of the total voting power of all the then outstanding Voting Securities; or

b. any Initial Investor is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of Voting Securities representing 50% or more of the total voting power of all the then outstanding Voting Securities; or

c. the individuals who, as of the date hereof, constitute the Board of Directors of the Company (the "Board") together with those who become directors subsequent to such date and whose recommendation, election or nomination for election to the Board was approved by a vote of at least a majority of the directors then still in office who


either were directors as of such date or whose recommendation, election or nomination for election was previously so approved, cease for any reason to constitute a majority of the members of the Board; or

d. the consummation of a merger, consolidation, recapitalization, liquidation, sale or disposition by the Company of all or substantially all of the Company's assets, or reorganization of the Company, other than any such transaction which would (x) result in at least 60% of the total voting power represented by the voting securities of the surviving entity or, in the case of an asset sale, the successor entity, outstanding immediately after such transaction being beneficially owned, directly or indirectly, by the stockholders of the Company immediately preceding the transaction and (y) not otherwise be deemed a Change in Control under subparagraphs a, b, c or e of this Section 2(a); or

e. the Board adopts a resolution to the effect that, for purposes hereof, a Change in Control has occurred.

(i) "Initial Investors" means (A) The Trident Partnership, L.P.; (B) Marsh & McLennan Risk Capital Holdings, Ltd.; or (C) any majority-owned subsidiary or parent (or equivalent in the case of a non-corporate entity) of the foregoing.

(ii) "Permitted Persons" means (A) the Company; (B) any Related Party; or (C) any group (as defined in Rule 13d-3 under the Exchange Act) comprised of any or all of the foregoing.

(iii) "Related Party" means (A) a majority-owned subsidiary of the Company; (B) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any majority-owned subsidiary of the Company; or (C) a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportion as their ownership of Voting Securities.

(iv) "Voting Security" means any security of the Company which carries the right to vote generally in the election of directors.

(b) TERMINATION OF SERVICE; FORFEITURE OF UNVESTED SHARES. In the event the Executive's services as Chairman of the Board of Directors of the Company cease (i) due to death or Disability (as defined in the Retention Agreement), or (ii) due to (A) termination by the Company without Cause (as defined in the Retention Agreement) or (B) Constructive Termination (as defined in the Retention Agreement), the Restricted Shares subject to the Award, to the extent not already vested in full, shall become immediately and fully vested at the time of such termination of service. If the Executive's services with the Company cease for any other reason, then a prorated portion of the Award based on the number of days the Executive served the Company during the calendar year of such termination shall become vested and the remaining portion of the Award shall be forfeited by the Executive and become the property of the Company. For purposes of this Agreement, service with any of the Company's wholly owned subsidiaries shall be considered to be service with the Company.

2

(c) CERTIFICATES. Each certificate issued in respect of Restricted Shares awarded hereunder shall be deposited with the Company, or its designee, together with, if requested by the Company, a stock power executed in blank by the Executive, and shall bear a legend disclosing the restrictions on transferability imposed on such Restricted Shares by this Agreement (the "Restrictive Legend"). Upon the vesting of Restricted Shares pursuant to Section 2(a) or 2(b) hereof and the satisfaction of any withholding tax liability pursuant to Section 5 hereof, the certificates evidencing such vested Shares, not bearing the Restrictive Legend, shall be delivered to the Executive.

(d) RIGHTS OF A STOCKHOLDER. Prior to the time a Restricted Share is fully vested hereunder, the Executive shall have no right to transfer, pledge, hypothecate or otherwise encumber such Restricted Share. During such period, the Executive shall have all other rights of a stockholder, including, but not limited to, the right to vote and to receive dividends at the time paid on such Restricted Shares.

(e) NO RIGHT TO CONTINUED SERVICES. This Award shall not confer upon the Executive any right with respect to continuance of services with the Company nor shall this Award interfere with the right of the Company to terminate the Executive's services at any time.

3. TRANSFER OF SHARES. The Shares delivered hereunder, or any interest therein, may be sold, assigned, pledged, hypothecated, encumbered, or transferred or disposed of in any other manner, in whole or in part, only in compliance with the terms, conditions and restrictions as set forth in the governing instruments of the Company, applicable United States federal and state securities laws or any other applicable laws or regulations and the terms and conditions hereof. Each certificate for Shares delivered hereunder, unless at the time of issuance such Shares are registered under the Securities Act of 1933, as amended, shall bear the following legend or such other legend as the Company deems appropriate:

"The securities evidenced hereby have not been registered under the Securities Act of 1933, as amended (the 'Act'), and may not be offered, sold or otherwise transferred except (i) in compliance with the provisions of any applicable state securities or 'Blue Sky' laws and
(ii) (A) pursuant to an effective registration under the Act, (B) in compliance with Rule 144 under the Act, (C) inside the United States to a Qualified Institutional Buyer in compliance with Rule 144A under the Act, (D) outside the United States in compliance with Rule 904 of Regulation S under the Act or (E) inside the United States to an institutional 'accredited investor' as defined in Rule 501(a)(1), (2),
(3) or (7) under the Act in a transaction which, in the opinion of counsel reasonably satisfactory to the Company, qualifies as an exempt transaction under the Act and the rules and regulations promulgated thereunder."

Any certificate issued at any time in exchange or substitution for any certificate bearing such legend or such other legend deemed appropriate by the Company shall also bear such legend unless, in the opinion of counsel for the Company, the securities represented thereby need no longer be subject to the restriction contained herein. The provisions of this Section 3 shall be binding upon all subsequent holders of certificates bearing the above legend.

4. EXPENSES OF ISSUANCE OF SHARES. The issuance of stock certificates hereunder shall be without charge to the Executive. The Company shall pay, and indemnify the Executive from and

3

against any issuance, stamp or documentary taxes (other than transfer taxes) or charges imposed by any governmental body, agency or official (other than income taxes) or by reason of the issuance of Shares.

5. WITHHOLDING. The Executive agrees to make appropriate arrangements with the Company for satisfaction of any applicable tax withholding requirements, or similar requirements, arising out of this Agreement.

6. REFERENCES. References herein to rights and obligations of the Executive shall apply, where appropriate, to the Executive's legal representative or estate without regard to whether specific reference to such legal representative or estate is contained in a particular provision of this Agreement.

7. SETTLEMENT OF DISPUTES. Any dispute between the parties arising from or relating to the terms of this Agreement shall be resolved by arbitration held in the State of Connecticut in accordance with the rules of the American Arbitration Association. All costs associated with any arbitration, including all legal expenses, for both parties shall be borne by the Company.

8. NO MITIGATION. To the extent that the vesting of any portion of the Award is accelerated upon a Change in Control or upon a termination of service as provided herein, neither the Shares delivered hereunder nor any interest therein, shall be reduced by any compensation received by the Executive in connection with any other employment.

9. NOTICES. Any notice required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been given when delivered personally or by courier, or sent by certified or registered mail, postage prepaid, return receipt requested, duly addressed to the party concerned at the address indicated below or to such changed address as such party may subsequently by similar process give notice of:

ARCH CAPITAL GROUP LTD

Director Option Agreement

FOR GOOD AND VALUABLE CONSIDERATION, receipt of which is hereby acknowledged, Arch Capital Group Ltd. (the "Company"), a Bermuda company, hereby grants to Michael P. Esposito, Jr., a director of the Company on the date hereof (the "Option Holder"), the option to purchase common shares, $.01 par value per share, of the Company ("Shares"), upon the following terms:

WHEREAS, the following terms reflect the Company's 1999 Long Term Incentive and Share Award Plan (the "Plan");

(a) GRANT. The Option Holder is hereby granted an option (the "Option") to purchase 1,500 Shares (the "Option Shares") pursuant to the Plan, the terms of which are incorporated herein by reference. The Option is granted as of January 1, 2001 (the "Date of Grant") and such grant is subject to the terms and conditions herein and the terms and conditions of the applicable provisions of the Plan. Such Option shall not be treated as an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended.

(b) STATUS OF OPTION SHARES. The Option Shares shall upon issue rank equally in all respects with the other Shares.

(c) OPTION PRICE. The purchase price for the Option Shares shall be, except as herein provided, $15.06 per Option Share, hereinafter sometimes referred to as the "Option Price," payable immediately in full upon the exercise of the Option.

(d) TERM OF OPTION. The Option may be exercised only during the period (the "Option Period") commencing in accordance with paragraph (f) below and shall continue until January 1, 2011; thereafter the Option Holder shall cease to have any rights in respect thereof. The right to exercise the Option may be subject to sooner termination as provided in paragraph (j) below.


(e) NO RIGHTS OF SHAREHOLDER. The Option Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or in equity.

(f) EXERCISABILITY. The Option shall become exercisable on January 1, 2002, subject to paragraph (j) below; provided that such Option, to the extent not already exercisable in full, shall become immediately and fully exercisable (1) to the extent provided in paragraph (j) below and (2) upon a Change in Control. Subject to paragraph (j) below, the Option may be exercised at any time or from time to time during the Option Period in regard to all or any portion of the Option which is then exercisable, as may be adjusted pursuant to paragraph (g) below.

"Change in Control" means any of the following occurring after the date hereof:

a. any person (within the meaning of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), other than a Permitted Person or Initial Investor, is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of Voting Securities representing 35% or more of the total voting power of all the then outstanding Voting Securities; or

b. any Initial Investor is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of Voting Securities representing 50% or more of the total voting power of all the then outstanding Voting Securities; or

c. the individuals who, as of the Date of Grant, constitute the Board of Directors of the Company (the "Board") together with those who become directors subsequent to such date and whose recommendation, election or nomination for election to the Board was approved by a vote of at least a majority of the directors then still in office who either were directors as of such date or whose recommendation, election or nomination for election was previously so approved, cease for any reason to constitute a majority of the members of the Board; or

d. the consummation of a merger, consolidation, recapitalization, liquidation, sale or disposition by the Company of all or substantially all of the Company's assets, or reorganization of the Company, other than any such transaction, other than any such transaction which would (x) result in at least 60% of the total voting power represented by the voting securities of the surviving entity or, in the case of an asset sale, the successor entity, outstanding immediately after such transaction being beneficially owned, directly or indirectly, by the stockholders of the Company immediately preceding the transaction and (y) not otherwise be deemed a Change in Control under subparagraphs a, b, c or e of this paragraph (f); or

e. the Board adopts a resolution to the effect that, for purposes hereof, a Change in Control has occurred.

(i) "Initial Investors" means (A) The Trident Partnership, L.P.; (B) Marsh & McLennan Risk Capital Holdings, Ltd.; or (C) any majority-owned subsidiary or parent (or equivalent in the case of a non-corporate entity) of the foregoing.

2

(ii) "Permitted Persons" means (A) the Company; (B) any Related Party; or (C) any group (as defined in Rule 13d-3 under the Exchange Act) comprised of any or all of the foregoing.

(iii) "Related Party" means (A) a majority-owned subsidiary of the Company; (B) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any majority-owned subsidiary of the Company; or
(C) a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportion as their ownership of Voting Securities.

(iv) "Voting Security" means any security of the Company which carries the right to vote generally in the election of directors.

(g) ADJUSTMENTS FOR RECAPITALIZATION AND DIVIDENDS. In the event that, prior to the expiration of the Option, 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 Option Holder and preserve the value of the Option, (i) there shall automatically be substituted for each Share subject to the unexercised Option 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 the unexercised Option shall remain the same as immediately prior to such event.

(h) TRANSFERABILITY. The Option may not be assigned or otherwise transferred, disposed of or encumbered by the Option Holder, other than by will or by the laws of descent and distribution. During the lifetime of the Option Holder, the Option shall be exercisable only by the Option Holder or by his or her guardian or legal representative. Notwithstanding the foregoing, the Option may be transferred by the Option Holder 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 Option Holder's "immediate family." Any Option held by the transferee will continue to be subject to the same terms and conditions that were applicable to the Option immediately prior to the transfer, except that the Option will be transferable by the transferee only by will or the laws of descent and distribution. For purposes hereof, "immediate family" means the Option Holder's children, stepchildren, grandchildren, parents, stepparents, grandparents, spouse, siblings (including half brothers and sisters), in-laws, and relationships arising because of legal adoption.

(i) EXERCISE OF OPTION. In order to exercise the Option, the Option Holder shall submit to the Company an instrument in writing signed by the Option Holder, specifying the number of Option Shares in respect of which the Option is being exercised, accompanied by payment of the Option Price for the Option Shares for which the Option is being exercised in cash or Shares already owned by the Option Holder (provided that the Option Holder has owned such Shares for a minimum period of six months) and having a total Fair Market Value (as defined below) equal to the exercise price, or in a combination of cash and such Shares. Option Shares will be issued accordingly by the Company within 15 business days, and a share certificate dispatched to the Option Holder within 30 days.

The Company shall not be required to issue fractional Shares upon the exercise of the Option. If any fractional interest in a Share would be deliverable upon the exercise of the Option in whole

3

or in part but for the provisions of this paragraph, the Company, in lieu of delivering any such fractional share therefor, shall pay a cash adjustment therefor in an amount equal to their Fair Market Value (or if any Shares are not publicly traded, an amount equal to the book value per share at the end of the most recent fiscal quarter) multiplied by the fraction of the fractional share which would otherwise have been issued hereunder. Anything to the contrary herein notwithstanding, the Company shall not be obligated to issue any Option Shares hereunder if the issuance of such Option Shares would violate the provision of any applicable law, in which event the Company shall, as soon as practicable, take whatever action it reasonably can so that such Option Shares may be issued without resulting in such violations of law. For purposes hereof, Fair 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.

(j) TERMINATION OF SERVICE. In the event the Option Holder ceases to be a director of the Company (i) due to retirement after attainment of age 65 or (ii) due to death or disability, the Option, to the extent not already exercisable in full, shall become immediately and fully exercisable at the time of such termination of service, and the Option may be exercised at any time during the Option Period. Subject to paragraph (f) above, if the Option Holder ceases to be a director of the Company for any other reason, the portion of the Option which is not then exercisable shall be cancelled on the date service terminates, and the portion of the Option which is then exercisable may be exercised at any time within six months after the date of such termination, but not later than termination of the Option Period.

(k) OBLIGATIONS AS TO CAPITAL. The Company agrees that it will at all times maintain authorized and unissued share capital sufficient to fulfill all of its obligations under the Option.

(l) TRANSFER OF SHARES. The Option, the Option Shares, or any interest in either, may be sold, assigned, pledged, hypothecated, encumbered, or transferred or disposed of in any other manner, in whole or in part, only in compliance with the terms, conditions and restrictions as set forth in the governing instruments of the Company, applicable United States federal and state securities laws and the terms and conditions hereof. Each certificate for Option Shares issued upon exercise of the Option, unless at the time of exercise such Option Shares are registered under the Securities Act of 1933, as amended, shall bear the following legend or such other legend as the Company deems appropriate:

"The securities evidenced hereby have not been registered under the Securities Act of 1933, as amended (the `Act'), and may not be offered, sold or otherwise transferred except (i) in compliance with the provisions of any applicable state securities or `Blue Sky' laws and (ii) (A) pursuant to an effective registration under the Act, (B) in compliance with Rule 144 under the Act, (C) inside the United States to a Qualified Institutional Buyer in compliance with Rule 144A under the Act, (D) outside the United States in compliance with Rule 904 of Regulation S under the Act or (E) inside the United States to an institutional `accredited investor' as defined in Rule 501(a)(1), (2), (3) or (7) under the Act in a transaction which, in the opinion of counsel reasonably satisfactory to the Company, qualifies as an exempt transaction under the Act and the rules and regulations promulgated thereunder."

Any certificate issued at any time in exchange or substitution for any certificate bearing such legend or such other legend deemed appropriate by the Company shall also bear such legend unless, in the opinion

4

of counsel for the Company, the securities represented thereby need no longer be subject to the restrictions set forth therein. The provisions of this paragraph
(l) shall be binding upon all subsequent holders of certificates bearing the above legend and all subsequent holders of the Option, if any.

(m) EXPENSES OF ISSUANCE OF OPTION SHARES. The issuance of stock certificates upon the exercise of the Option in whole or in part, shall be without charge to the Option Holder. The Company shall pay, and indemnify the Option Holder from and against any issuance, stamp or documentary taxes (other than transfer taxes) or charges imposed by any governmental body, agency or official (other than income taxes) by reason of the exercise of the Option in whole or in part or the resulting issuance of the Option Shares.

(n) WITHHOLDING. The Option Holder agrees to make appropriate arrangements with the Company for satisfaction of any applicable tax withholding requirements, or similar requirements, arising out of the Option.

(o) REFERENCES. References herein to rights and obligations of the Option Holder shall apply, where appropriate, to the Option Holder's legal representative or estate without regard to whether specific reference to such legal representative or estate is contained in a particular provision of this Option.

(p) SETTLEMENT OF DISPUTES. Any dispute between the parties arising from or relating to the terms of this Option shall be resolved by arbitration held in the State of Connecticut in accordance with the rules of the American Arbitration Association. All costs associated with any arbitration, including all legal expenses, for both parties shall be borne by the Company.

(q) NO MITIGATION.

Appel, and the Employment and Change in Control Agreement, dated as of May 5, 2000, between the Company and Louis T. Petrillo (collectively, the "Agreements").

The Agreements provide that the Company will require any successor to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform the Agreements in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place.

As a result of the Merger, the stockholders of the Company will become stockholders of the Parent, and the Company will become a wholly owned subsidiary of the Parent.

Effective with the consummation of the Merger, the Parent hereby assumes all of the Company's rights and obligations under the Agreements; all references to the "Company" in the Agreements shall be to the Parent; and the Company is released from all of its obligations under the Agreements.

Exhibit 10.15

FIRST AMENDED AND RESTATED ESCROW AGREEMENT

THIS FIRST AMENDED AND RESTATED ESCROW AGREEMENT (this "FIRST RESTATEMENT") is made and entered into as of December 28, 2000, by and among FOLKSAMERICA HOLDING COMPANY, INC., a New York corporation ("FHC"), FOLKSAMERICA REINSURANCE COMPANY, a New York domiciled insurance company ("FRC," and, together with FHC, "BUYER") and a wholly owned subsidiary of FHC, ARCH CAPITAL GROUP LTD., a corporation organized under the laws of Bermuda ("ACGL"), and Citibank, N.A., as Escrow Agent (the "ESCROW AGENT"). Certain capitalized terms have the meanings given to them in Annex A hereto.

W I T N E S S E T H :

WHEREAS, Buyer, Arch Reinsurance Company, a Nebraska domiciled insurance company and wholly owned subsidiary of ACGL ("ARCH RE") and Arch Capital Group (U.S.) Inc., a Delaware corporation and wholly owned subsidiary of ACGL, are parties to an Asset Purchase Agreement, dated as of January 10, 2000 (the "PURCHASE AGREEMENT");

WHEREAS, pursuant to the Purchase Agreement, on May 5, 2000 (the "CLOSING DATE") Buyer purchased all of the reinsurance operations of Arch Re, and contemporaneously therewith, entered into an escrow agreement dated of the Closing Date with Arch Re and the Escrow Agent (the "ORIGINAL ESCROW
AGREEMENT");

WHEREAS, upon the execution and delivery of this First Restatement, this First Restatement shall replace the Original Escrow Agreement in its entirety and all references to the Escrow Agreement in the Purchase Agreement shall hereinafter be deemed to refer to this First Restatement;

NOW, THEREFORE, in consideration of the mutual promises and agreements set forth in this First Restatement, the parties hereto hereby agree as follows:

1. APPOINTMENT OF ESCROW AGENT. Each of Buyer and ACGL hereby designates and appoints the Escrow Agent as escrow agent, and the Escrow Agent hereby accepts such appointment, on the terms and subject to the conditions of this First Restatement.


-2-

2. DEPOSITED AMOUNT; ESCROWED FUNDS; ESCROW ACCOUNT.

(a) Concurrently with the execution and delivery of this First Restatement, ACGL hereby delivers to the Escrow Agent, as custodian, the Deposited Amount, the receipt of which the Escrow Agent hereby acknowledges. The securities constituting the Deposited Amount are listed and described on Schedule 1 hereto. The Deposited Amount constitutes a portion of the purchase price received by ACGL from Buyer under the Purchase Agreement.

(b) The Escrow Agent shall establish a segregated account (the "ESCROW ACCOUNT") at its office located at its address set forth in Section 11 in which to hold the Escrowed Funds and any securities in which the Escrowed Funds may, from time to time, be invested. The Escrow Agent shall keep appropriate books and records for the Escrow Account, including a list of securities in which the Escrowed Funds are invested, any interest, dividends or other distributions on or proceeds from any investment of Escrowed Funds and any amounts released from the Escrow Account in accordance with Section 6. At the written request of Buyer or ACGL from time to time, the Escrow Agent shall allow representatives of such party to inspect and make copies of such books and records upon reasonable notice during normal business hours. In any event, within 30 days of the end of each calendar quarter, the Escrow Agent shall, upon request, provide to Buyer and ACGL a statement of the list of securities in which the Escrowed Funds are invested, the amount of any interest, dividends or other distributions on or proceeds from any investment of Escrowed Funds and any amounts released from the Escrow Account in accordance with Section 6. Escrowed Funds shall not be available to, and shall not be used by, the Escrow Agent to set off any obligations of either Buyer or ACGL owing to the Escrow Agent in any capacity, except as set forth in Sections 8(e) and 8(f).

3. INVESTMENT OF ESCROWED FUNDS.

(a) Except as provided in Section 3(d), all investments and reinvestments of the Escrowed Funds shall be made exclusively in Permitted Investments that are mutually selected by Buyer and ACGL.

(b) From time to time, Buyer and ACGL shall designate an entity with the appropriate capacity to act as broker (the "BROKER") with respect to the securities that constitute the Escrowed Funds. Broker will perform such acts as requested by Buyer and ACGL which are customarily performed by securities brokers. The fees and expenses of Broker shall be borne one-half by ACGL and one-half by Buyer. If at any time or from time to time during the term of this First Restatement, Buyer or ACGL determines that the Broker appointed pursuant to the first sentence of this Section 3(b) should terminate acting in such capacity, Buyer and ACGL agree to cooperate with each other to jointly select and appoint an entity which is capable of conducting the duties performed by Broker to replace Broker. Upon any such re-


-3-

placement, all references to Broker in this First Restatement shall be deemed references to such entity. Broker shall not be deemed the beneficial holder of any securities which may be in its possession as a result of its activities pursuant to this Section 3(b), and Broker shall hold any such securities as agent and may only act with respect to such securities pursuant to the joint written instructions of Buyer and ACGL.

(c) Promptly after the Escrow Agent receives written notice from the issuer thereof (or any representative of such issuer) that any security that is a component of the Escrowed Funds is to be redeemed or otherwise liquidated by such issuer, the Escrow Agent shall deliver written notice thereof to Buyer and ACGL. Promptly after receipt of such notice, Buyer and ACGL shall deliver to the Escrow Agent joint written instructions as to whether the cash proceeds from any such redemption, liquidation or maturation are (i) to be delivered to Broker for the purpose of promptly reinvesting such proceeds or
(ii) to be held in the Escrow Account in the form of cash (which cash may be invested pursuant to the provisions of Section 3(f)). In the case of clause (i), the Escrow Agent shall promptly deliver to Broker such proceeds in accordance with such written instructions, and promptly upon consummation of such reinvestment, Broker shall deliver to the Escrow Agent the security or securities that Buyer and ACGL have elected to so purchase. In the event that Buyer and ACGL do not provide the Escrow Agent with written instructions pursuant to the provisions of this Section 3(c), the proceeds from any such maturation, redemption or liquidation shall remain in the Escrow Account in the form of cash (which cash may be invested pursuant to the provisions of Section 3(f)).

(d) At any time that there is cash in the Escrow Account, the Escrow Agent is hereby directed to invest such cash promptly in the Citibank Money Market Deposit Account (the "CITIBANK MMDA") fund. All references to the term "cash" in this First Restatement shall be deemed to refer to cash as well as any portion of the Escrowed Funds that are invested in the Citibank MMDA fund.

(e) The Escrow Agent shall have no obligation to invest or reinvest any cash portion of Escrowed Funds (pursuant to Section 3(d)) if such funds are deposited or delivered to the Escrow Agent after 11 a.m. (E.S.T.) on such day of deposit or delivery until the following business day. Requests or instructions of Buyer and ACGL to deliver securities to the Broker, whether pursuant to Section 3 or Section 6(g), received after 11 a.m. (E.S.T.) by the Escrow Agent shall be treated as if received on the following business day, and Escrow Agent will carry out such requests or instructions on such day.

(f) At any time and from time to time, Buyer and ACGL may jointly determine that any security that is a component of the Escrowed Funds is to be liquidated or reinvested in a replacement security, or that any cash (whether such cash constitutes investment income or otherwise) that is a component of the Escrowed Funds is to be invested. Buyer and


-4-

ACGL shall provide the Escrow Agent with joint written notice of such determination, which shall identify such security or specify the dollar amount of such cash and direct the Escrow Agent to deliver such security or dollar amount of such cash to Broker for the purpose of the liquidation or reinvestment of such security or the investment of such cash. Promptly upon the receipt of such notice, the Escrow Agent shall promptly deliver such security or such cash to Broker and Broker shall promptly effect such reinvestment or liquidation of such security or investment of such cash, as the case may be. Promptly upon consummation of such reinvestment, investment or liquidation, as the case may be, Broker shall deliver to the Escrow Agent the security or securities that Buyer and ACGL have elected to so purchase or cash proceeds from such liquidation, as the case may be. Any cash produced by the operation of this
Section 3(f) may be invested pursuant to the provisions hereof.

(g) In the event that the Escrow Agent receives written notice from the issuer thereof (or any representative of the issuer) that a security that is a component of the Escrowed Funds is to be exchanged for a new security, the Escrow Agent shall promptly notify Buyer and ACGL thereof in writing. Unless otherwise directed in writing by Buyer and ACGL (pursuant to the provisions of
Section 3(f)), such new security shall become a component of the Escrowed Funds upon consummation of such exchange.

(h) The Escrow Agent shall have no responsibility for any investment losses resulting from the investment, reinvestment or liquidation of the Escrowed Funds. Any interest or other income received on such investment and reinvestment of the Escrowed Funds shall become part of the Escrowed Funds.

(i) In the event that any decisions concerning voting, redemption or other similar matters relating to the securities constituting the Escrowed Funds are required to be made, the Escrow Agent shall promptly notify ACGL thereof in writing. Upon receipt of such notice, ACGL shall instruct the Escrow Agent in writing with respect to the making of such decision.

(j) Any securities that are delivered to any party pursuant to the terms of this First Restatement shall be accompanied by duly executed instruments of transfer or assignment, or if such securities are held in book-entry form, other appropriate action shall be taken by the entity delivering such securities to effect the valid transfer of the title of such securities to the recipient of such securities.

4. REPORTS ON PAID LOSSES, ENDING RESERVES AND RESERVE DEFICIENCY/REDUNDANCY CALCULATION. As soon as practicable (but not later than ninety (90) days) after the Valuation Date, Buyer shall deliver to ACGL and the Escrow Agent each of the following (it being understood that the Escrow Agent shall have no duty to solicit the items listed below or verify their content):


-5-

(i) A report of independent public accountants designated in writing by Buyer (who may also be the independent public accountants of ACGL or Buyer) setting forth the amount of Paid Losses and showing in reasonable detail the calculation thereof.

(ii) A report by an independent actuary designated in writing by Buyer (who may also be the independent actuary of ACGL or Buyer, but not an employee of either) setting forth the amount of Ending Reserves and showing in reasonable detail the calculation thereof.

(iii) A report of independent public accountants designated in writing by Buyer (who may also be the independent public accountants of ACGL or Buyer) setting forth the difference of (1) the Beginning Reserves over (2) the sum of Paid Losses plus Ending Reserves. Such difference shall be called "RESERVE DEFICIENCY" if it is negative and "RESERVE REDUNDANCY" if it is zero or positive. The Reserve Deficiency shall not exceed the Deposited Amount. Such report shall show such calculation in reasonable detail.

5. DISPUTES.

(a) If at any time within the Objection Period ACGL gives an Objection Notice, Appointed Experts shall be engaged to separately determine the Reserve Deficiency/Reserve Redundancy, and/or Ending Reserves and confirm the calculation of Paid Losses. The identity of such Appointed Experts shall be disclosed to the Escrow Agent by Buyer and ACGL in writing, and Buyer and ACGL shall arrange for the Escrow Agent to obtain an incumbency certificate or other instrument satisfactory to the Escrow Agent for the purpose of verifying the genuineness of signatures on any written instructions received from the Appointed Experts. The Appointed Experts shall determine the Reserve Deficiency/Reserve Redundancy, and/or Ending Reserves and confirm the calculation of Paid Losses within forty-five (45) days of the date ACGL gives such notice. The determination by an actuary that is an Appointed Expert shall be conducted (x) using its independent judgment based on prevailing facts, circumstances and trends, (y) in accordance with generally accepted actuarial standards and principles, and (z) to the extent not inconsistent with the foregoing, in a manner and applying a method consistent with the determination of the Beginning Reserves. It is understood that such actuary shall in no way be inhibited in the use of its independent judgment. Except as provided in Section
5(c), the Appointed Experts' determinations and confirmations shall be final and binding on all parties. Fees and expenses of the Appointed Experts shall be paid equally by Buyer and ACGL.

(b) Buyer and ACGL agree to cooperate with and use all commercially reasonable efforts to assist the Appointed Experts, including by furnishing all information rea-


-6-

sonably requested by them, in performing the services specified hereby, and to negotiate in good faith to resolve the disputes under Section 5(a).

(c) ACGL shall be entitled to dispute Paid Losses the calculation of which shall have been confirmed by the Appointed Experts only to the extent that ACGL can show Paid Losses shall not have been incurred by Buyer in its exercise of the reasonable business judgment of a reasonable reinsurer under similar circumstances without regard to the availability of the Escrow Funds (it being recognized that Buyer's rights to control payment of losses by cedents are limited).

6. RELEASE OF ESCROWED FUNDS. Escrowed Funds shall be released from the Escrow Account only in accordance with this Section 6 to those accounts designated in Annex B.

(a) TAX DISTRIBUTIONS. Within two business days after the end of each calendar quarter (beginning with December 31, 2000), the Escrow Agent shall, upon its receipt of a written request from ACGL, release from the Escrow Account and deliver to ACGL Escrowed Funds in an amount equal to the tax that ACGL notifies Buyer and the Escrow Agent in writing is actually payable (after giving effect to ACGL's net operating losses) by ACGL in respect of earnings on the Escrowed Funds since the end of the immediately preceding calendar quarter
(or, in the case of the first such calendar quarter, since the date hereof) (such amounts, collectively, the "TAX DISTRIBUTIONS"). The parties agree that no release of any Escrowed Funds shall be made by the Escrow Agent pursuant to this
Section 6(a) in respect of any taxes which may be payable by either ACGL or Buyer as a result of the parties entering into this First Restatement. Buyer shall have no right to dispute the amount of taxes so notified by ACGL.

(b) BY MUTUAL INSTRUCTIONS. The Escrow Agent shall release Escrowed Funds from the Escrow Account in accordance with any joint written instruction of both Buyer and ACGL.

(c) INSURANCE ON RESERVE DEFICIENCY. The Escrow Agent shall release to ACGL all of the Escrowed Funds from the Escrow Account upon the Escrow Agent's receipt of written confirmation and instructions from ACGL and Buyer (which Buyer shall not unreasonably withhold) that ACGL has delivered to Buyer an insurance policy for the benefit of Buyer from an insurance company (which insurance company shall have a claims paying ability rating from Standard & Poor's at such time at least as high as Buyer (but no less than "AA-") and a combined capital and surplus at such time of at least as much as Buyer (but no less than $500 million)) or other similar arrangement guaranteeing payment to Buyer on the Settlement Date of the Reserve Deficiency plus interest on the Reserve Deficiency from the Closing Date to the Settlement Date at the average rate of return on the Escrow Funds from


-7-

the date hereof to the date of such release. Such insurance policy or other similar arrangement shall not detract from or adversely affect the rights of Buyer or ACGL provided for in this First Restatement and shall incorporate the relevant terms of this First Restatement, which shall under the terms of such insurance policy apply to such insurance policy rather than to the Escrowed Funds.

(d) PAID LOSSES IN EXCESS OF BEGINNING RESERVES.

(i) At the end of the first calendar quarter in which Paid Losses (calculated with the references to "Valuation Date" in the definition thereof being to such quarter-end and subject to Section
5(c)) exceed the Beginning Reserves (such excess, the "EXCESS"), Buyer may give written notice of the Excess to ACGL. Such notice shall be accompanied by a report of independent public accountants designated by Buyer (who may also be the independent public accountants of ACGL or Buyer) setting forth the amount of Paid Losses and showing in reasonable detail the calculation thereof. If at any time within thirty
(30) days of the receipt of such notice, ACGL gives written notice to Buyer that it disputes the Paid Losses or any component thereof, Appointed Experts shall be engaged to confirm the calculation of Paid Losses. The Appointed Experts shall confirm the calculation of the Paid Losses within forty-five (45) days of the date ACGL gives such notice, and give written notice and instructions to the Escrow Agent with respect to the amount of the Excess. Except as provided in Section
5(c), the Appointed Experts' confirmation of the calculation shall be final and binding on all parties. On the later of (A) the end of the 30-day period referred to in this Section 6(d)(i) and (B) the delivery by the Appointed Experts of their confirmation of the calculation of the Excess, the Escrow Agent shall, upon its receipt of written instructions from the Appointed Experts, release from the Escrow Account and deliver to Buyer Escrowed Funds in an amount equal to any Excess.

(ii) Following the release of Escrowed Funds pursuant to
Section 6(d)(i), from time to time, Buyer shall give written notice to ACGL of Paid Losses since the last such release to the end of any subsequent calendar quarter ("ADDITIONAL PAID LOSSES"), accompanied by a reasonably detailed report of Buyer's calculation of such Additional Paid Losses, at the end of such calendar quarter. Upon the receipt of such report and written instructions of Buyer, the Escrow Agent shall release from the Escrow Account and deliver to Buyer Escrowed Funds in an amount equal to such Additional Paid Losses.

(iii) The release of Escrowed Funds pursuant to Section 6(d) shall not affect the right of ACGL to dispute the amount of Paid Losses included in any Reserve Deficiency or Reserve Redundancy submitted by or on behalf of Buyer.


-8-

(e) RESERVE DEFICIENCY/REDUNDANCY. On the Settlement Date:

(i) if there is a Reserve Deficiency, (x) the Escrow Agent shall, upon its receipt of joint written instructions of Buyer and ACGL or written instructions from the Appointed Experts, release from the Escrow Account and deliver to Buyer the Buyer Portion in accordance with the written instructions received by it and (y) the Escrow Agent shall, upon its receipt of joint written instructions of Buyer and ACGL or written instructions from the Appointed Experts, release from the Escrow Account and deliver to ACGL the ACGL Portion in accordance with the written instructions received by it.

(ii) if there is a Reserve Redundancy, (x) the Escrow Agent shall, upon its receipt of joint written instructions of Buyer and ACGL or written instructions from the Appointed Experts, release from the Escrow Account and deliver to ACGL all of the Escrowed Funds and (y) Buyer shall deliver to ACGL cash equal to the amount of Reserve Redundancy, plus interest on such amount at the average rate of return on the Escrowed Funds from the Closing Date to the Settlement Date.

(f) INDEMNIFICATION. Upon the final determination of any Covered Claim, the Escrow Agent shall, upon receipt of written instructions from Buyer and ACGL, release from the Escrow Account and deliver to Buyer Escrowed Funds in an amount up to the amount payable to Buyer by ACGL in respect of such claim. If the amount so payable to Buyer by ACGL in respect of the Covered Claim exceeds the amount of Escrowed Funds, ACGL shall deliver to Buyer cash equal to the lesser of (A) the amount of such excess and (B) the total amount of Tax Distributions released from the Escrow Account to ACGL pursuant to Section 6(a), plus an amount of interest on such Tax Distributions from the release date at a rate equal to the weighted average return on the Deposited Amount to the Settlement Date, less any amounts paid to Buyer pursuant to clause (iii) of the definition of Buyer's Portion. In such event, Buyer shall cooperate in any of ACGL's efforts to seek a refund of or tax benefit with respect to income taxes paid or tax benefits used by ACGL in respect of earnings on Escrowed Funds.

(g) PAYMENTS. All payments shall be made by wire transfer of immediately available funds to the account specified by such payee; PROVIDED, that the payee receiving such immediately available funds may (i) extend in writing any payment period provided for in Section 6 in order to avoid any loss of income or principal from a premature liquidation of any of the securities constituting the Escrowed Funds and/or (ii) opt in writing to receive securities from the Escrow Account rather than immediately available funds. If securities are to be delivered to any payee, then appropriate delivery instructions shall be delivered to the Escrow Agent by such payee not less than three business days before such payment is made. In the event that it is necessary for the Escrow Agent to liquidate securities in the Escrow Ac-


-9-

count in order to make a payment pursuant to this Section 6, the Escrow Agent shall notify Buyer and ACGL thereof in writing. Promptly upon receipt of such written notice, Buyer and ACGL shall mutually select the requisite amount of securities to be liquidated and notify the Escrow Agent of the identity of such securities in writing. Upon receipt of such notice, the Escrow Agent shall deliver such security or securities to Broker, and Broker shall liquidate such security or securities and promptly deliver the cash proceeds therefrom to the Escrow Agent. Any cash resulting from such liquidation which exceeds the amount of the payment to be made pursuant to this Section 6(g) may be invested pursuant to the provisions of Section 3(f). All wire transfers of immediately available funds shall be made to the accounts specified by Buyer and ACGL in Annex B hereto or to such other accounts specified by Buyer or ACGL, as the case may be, in accordance with Section 11. For the avoidance of doubt, unless otherwise indicated in writing, all releases of Escrowed Funds will be made in accordance with the wire instructions appearing on Annex B.

(h) Upon payment of any amount to Buyer by (1) ACGL pursuant to the ACGL Guarantee or (2) by Arch Re pursuant to the Arch Re Agreement, the Escrow Agent shall, in each case, upon written notification thereof from ACGL or Arch Re, immediately release Escrowed Funds in an amount equal to any such payment to ACGL, in the manner and to an account designated by ACGL.

(i) The Escrow Agent, in making a release of Escrowed Funds pursuant to this Section 6, shall be entitled (and shall incur no liability in relying upon) to rely on the written instructions given to it either jointly by Buyer and ACGL or the Appointed Experts. Neither Buyer nor ACGL shall direct a release of the Escrowed Funds in a manner inconsistent with the terms of this First Restatement.

7. REPORTS; INSPECTION RIGHTS.

(a) Within 45 days of the end of each of the first three fiscal quarters of Buyer of each year prior to the Valuation Date, Buyer shall deliver to ACGL a report setting forth (i) the Paid Losses (for such purposes, the references to Valuation Date and financial statements in the definition thereof being to such quarter-end and interim financial statements, respectively), (ii) the Reserves as of such quarter-end, (iii) the calculation of each of the foregoing in reasonable detail (including in the case of Paid Losses, a list of all individual losses, if available from the ceding company), and (iv) such other related matters as ACGL reasonably requests, to the extent reasonably available.

(b) Within 90 days of the end of each fiscal year of Buyer prior to the Valuation Date, Buyer shall deliver to ACGL a report setting forth
(i) the Paid Losses (for such purposes, the references to Valuation Date and financial statements in the definition thereof being to such year-end and year-end financial statements), (ii) the Reserves as of such


-10-

year-end, (iii) the difference of (1) the Beginning Reserves over (2) the sum of Paid Losses (calculated with the references to "Valuation Date" in the definition thereof being to such year-end) plus the Reserves as of such year-end, (iv) the calculation of each of the foregoing in reasonable detail (including in the case of Paid Losses, a list of all individual losses, if available from the ceding company) and (v) such other related matters as ACGL reasonably requests, to the extent reasonably available.

(c) From time to time as Buyer and ACGL may reasonably agree (but not less frequently than once per year) upon reasonable notice during normal business hours, representatives of ACGL (including its independent public accountants and actuary) shall be permitted to inspect Buyer's books and records involving the CPIS Business, including those relating to settlement and payment of claims and work papers of Buyer's independent public accountants and actuary, and, at ACGL's expense, to make copies of them, and to discuss them with Buyer's representatives (including its independent public accountants and actuaries).

(d) The parties agree that ACGL's receipt of reports or information pursuant to this Section 7 shall not affect ACGL's rights under
Section 5 or 6.

(e) Buyer agrees that, without the prior approval of ACGL (which approval is not to be unreasonably withheld or unreasonably delayed), it will not commute any reinsurance, retrocession or similar contracts, treaties, agreements or arrangements covering the CPIS Business (it being understood that, with respect to commutations of up to $500,000, ACGL's failure to respond within 30 Business Days to a request by Buyer for such approval shall be deemed an unreasonable delay). Buyer shall not otherwise take any action which is other than in the ordinary course of business of Buyer with respect to the Reserves. This Section 7(e) shall not limit a ceding company's ability to settle claims in the ordinary course of business.

8. RESPONSIBILITY OF ESCROW AGENT.

(a) In the event of any ambiguity or uncertainty hereunder or in any notice, instruction or other communication received by the Escrow Agent hereunder, the Escrow Agent may, in its reasonable discretion, refrain from taking any action, unless the Escrow Agent receives written instructions, signed by both Buyer and ACGL, which eliminates such ambiguity or uncertainty.

(b) The Escrow Agent shall be entitled to retain counsel both to advise it and in connection with any court action, and such counsel's reasonable attorneys' fees shall be borne by Buyer and ACGL, jointly and severally, pursuant to Section 9. The Escrow Agent shall be entitled to act in reliance upon the advice of counsel in all matters pertaining to this First Restatement, and shall not be liable for any action taken, suffered or omitted by it in ac-


-11-

cordance with such advice and in the absence of gross negligence or willful misconduct by the Escrow Agent.

(c) In the event of any dispute between or conflicting claims by or between Buyer and ACGL and/or any other person or entity with respect to any Escrowed Funds, the Escrow Agent shall be entitled, in its reasonable discretion, to refuse to comply with any and all claims, demands or instructions with respect to such Escrowed Funds so long as such dispute or conflict shall continue, and the Escrow Agent shall not be or become liable in any way to Buyer or ACGL for failure or refusal to comply with such conflicting claims, demands or instructions. The Escrow Agent shall be entitled to refuse to act until, in its reasonable discretion, either (i) such conflicting or adverse claims or demands shall have been determined by a final order, judgment or decree of a court of competent jurisdiction, which order, judgment or decree is not subject to appeal, or settled by agreement between the conflicting parties as evidenced in a writing reasonably satisfactory to the Escrow Agent or (ii) the Escrow Agent shall have received security or an indemnity reasonably satisfactory to it sufficient to hold it harmless from and against any and all losses which it may incur by reason of so acting. Any court order, judgment or decree shall be accompanied by a legal opinion by counsel for the presenting party, reasonably satisfactory to the Escrow Agent, to the effect that said order, judgment or decree represents a final adjudication of the rights of the parties by a court of competent jurisdiction, and that the time for appeal from such order, judgment or decree has expired without an appeal having been perfected. The Escrow Agent shall act on such court order and legal opinions without further question. The Escrow Agent may, in addition, elect, in its reasonable discretion, to commence an interpleader action or seek other judicial relief or orders as it may deem, in its reasonable discretion, necessary. The costs and expenses (including reasonable attorneys' fees and expenses) incurred in connection with such proceeding shall be borne equally by, and shall be deemed a joint and several obligation of, Buyer and ACGL.

(d) If at any time the Escrow Agent is served with any judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process which in any way affects the Escrowed Funds (including but not limited to orders of attachment or garnishment or other forms of levies or injunctions or stays relating to the transfer of the Escrowed Funds), the Escrow Agent shall promptly provide written notice thereof to Buyer and ACGL and the Escrow Agent is authorized to comply therewith in any manner it or legal counsel of its own choosing deems appropriate; and if the Escrow Agent complies with any such judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process, the Escrow Agent shall not be liable to any of the parties hereto or to any other person or entity even though such order, judgment, decree, writ or process may be subsequently modified or vacated or otherwise determined to have been without legal force or effect.


-12-

(e) If any fees under Section 10 hereof or obligations under
Section 9 hereof (which indemnification obligations are (i) determined by a final order, judgment or decree of a court of competent jurisdiction, which order, judgment or decree is not subject to appeal or (ii) settled by written agreement among the parties) owed to Escrow Agent or its counsel hereunder are not promptly paid when due, Escrow Agent may, upon 10 business days' written notice to both Buyer and ACGL, reimburse itself therefor from the Escrowed Funds and may sell, convey or otherwise dispose of any Escrowed Funds for such purpose. The Escrow Agent may in its sole discretion withhold from any distribution of Escrowed Funds an amount of Escrowed Funds it believes would, upon sale or liquidation, produce proceeds equal to any unpaid amounts to which Escrow Agent is entitled hereunder.

(f) As security for the rights of the Escrow Agent under this First Restatement, Buyer and ACGL, individually and collectively, hereby pledge, assign and grant to Escrow Agent a continuing security interest in, and a lien on, the Escrowed Funds. The security interest of Escrow Agent shall at all times be valid, perfected and enforceable by Escrow Agent against Buyer and ACGL and all third parties in accordance with the terms of this First Restatement.

(g) The duties and obligations of the Escrow Agent hereunder shall be governed solely by the provisions of this First Restatement, and the Escrow Agent shall have no duties other than the duties expressly imposed herein and shall not be required to take any action other than in accordance with the terms hereof. The Escrow Agent shall not be bound by any notice of, or demand with respect to, any waiver, modification, amendment, termination, cancellation, rescission or supersession of this First Restatement, unless in writing and signed by Buyer, ACGL and the Escrow Agent. The Escrow Agent shall not be required to expend or risk any of its own funds or otherwise incur any financial or other liability in the performance of any of its duties hereunder.

(h) The Escrow Agent shall not be liable for any action taken or omitted or for any loss or injury resulting from its actions or its performance or lack of performance of its duties hereunder in the absence of gross negligence or willful misconduct on its part. In no event shall the Escrow Agent be liable (i) for acting in accordance with or relying upon any mutual written instruction, notice, demand, certificate or document jointly from Buyer and ACGL or entities acting on their behalf, (ii) for any indirect, consequential, punitive or special damages, regardless of the form of action and whether or not any such damages were foreseeable or contemplated, (iii) for the acts or omissions of its nominees, correspondents, designees, agents, subagents or subcustodians, (iv) for the investment or reinvestment of any cash held by it hereunder, in each case in good faith, in accordance with the terms hereof, including without limitation any liability for any delays (not resulting from its gross negligence or willful misconduct) in the investment or reinvestment of the Escrowed Funds, or any loss of inter-


-13-

est incident to any such delays, or (v) for an amount in excess of the value of the Escrowed Funds, valued as of the date of deposit, but only to the extent of direct money damages.

(i) The Escrow Agent shall not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of the Escrow Agent (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God or war, or the unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility).

(j) The Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity or the service thereof. The Escrow Agent may act in reliance upon any instrument or signature believed by it to be genuine and may assume that any person purporting to give receipt or advice to make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so by the party giving such receipt or advice.

(k) The Escrow Agent shall not be responsible in any respect for the form, execution, validity, value or genuineness of documents or securities deposited hereunder, or for any description therein, or for the identity, authority or rights of persons executing or delivering or purporting to execute or deliver any such document, security or endorsement. The Escrow Agent shall not be called upon to advise any party as to the wisdom in selling or retaining or taking or refraining from any action with respect to any securities or other property deposited hereunder.

ACGL shall pay all income taxes relating to the Escrowed Funds incurred in connection herewith (from the distributions made to it pursuant to Section 6(a)) and Buyer and ACGL, jointly and severally, shall indemnify and hold harmless the Escrow Agent from any amounts that it is obligated to pay in the way of such taxes. Any payments of taxable income from this Escrow Account shall be subject to withholding regulations then in force with respect to United States taxes. ACGL will provide the Escrow Agent with appropriate W-9 forms for tax I.D. number certifications, or W-8 forms for non-resident alien certifications. This paragraph shall survive notwithstanding any termination of this First Restatement or the resignation or removal of the Escrow Agent.


-14-

(m) The Escrow Agent shall not be under any duty to give the Escrowed Funds held by it hereunder any greater degree of care than it gives its own similar property and shall not be required to invest any funds held hereunder except as directed in this First Restatement. Uninvested funds held hereunder shall not earn or accrue interest.

9. INDEMNIFICATION OF ESCROW AGENT. Buyer and ACGL, jointly and severally, shall be liable for and shall reimburse and indemnify Escrow Agent (and any predecessor Escrow Agent) and hold Escrow Agent harmless from and against any and all claims, losses, actions, liabilities, costs, damages or expenses (including reasonable attorneys' fees and expenses) (collectively "LOSSES") arising from or in connection with its administration of this First Restatement, provided, however, that nothing contained herein shall require Escrow Agent to be indemnified for Losses caused by its own gross negligence or own willful misconduct. In addition, when the Escrow Agent acts on any information, instructions, communications, (including, but not limited to, communications with respect to the delivery of securities or the wire transfer of funds) sent by telex or facsimile, the Escrow Agent, absent gross negligence, shall not be responsible or liable in the event such communication is not an authorized or authentic communication of Buyer and ACGL or is not in the form Buyer and ACGL sent or intended to send (whether due to fraud, distortion or otherwise). Buyer and ACGL shall jointly and severally indemnify the Escrow Agent against any loss, liability, claim or expense (including legal fees and expenses) it may incur with its acting in accordance with any such communication. This paragraph shall survive the resignation or termination of this First Restatement or the removal of the Escrow Agent.
