Item 4. Purpose Of The Transaction. The purpose of the acquisition of the Preference A Shares and the Warrants (including Common Shares issued upon conversion or exercise thereof) is for investment, and the acquisitions of the Preference A Shares and the Warrants by each of the Partnerships were made in the ordinary course of business and were not made for the purpose of acquiring control of the Company. Although no Reporting Person has any specific plan or proposal to acquire or dispose of Common Shares, Preference A Shares or Warrants, consistent with its investment purpose, each Reporting Person at any time and from time to time may acquire additional Common Shares, Preference A Shares and Warrants or dispose of any or all of its Common Shares, Preference A Shares and/or Warrants depending upon an ongoing evaluation of the investment in the Common Shares, Preference A Shares and/or Warrants, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Person and/or other investment considerations. No Reporting Person has made a determination regarding a maximum or minimum number of Common Shares, Preference A Shares and/or Warrants which it may hold at any point in time. Also, consistent with their investment intent, the Reporting Persons may engage in communications with one or more shareholders of the Company, one or more officers of the Company and/or one or more members of the board of directors of the Company regarding the Company, including but not limited to its operations. Except to the extent the foregoing may be deemed a plan or proposal and except for the agreements described below, none of the Reporting Persons has any plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto. Preference A Shares Pursuant to the Certificate of Designations of Series A Convertible Preference Shares (the "Preference A Certificate"), each holder of the Preference A Shares is entitled to the number of votes equal to the number of whole Common Shares into which all of such holder's Preference A Shares are convertible, with respect to all matters submitted for shareholder approval. The Preference A Shares, subject to certain limitations, voting with holders of shares of all other series of preference shares affected in the same way as a single class, have the right to approve amendments, repeals or changes to any provisions of Preference A Certificate which would adversely affect, alter or change the powers, preferences or special rights of the Preference A Shares and such securities affected in the same way. Notwithstanding the foregoing, prior to the receipt of certain regulatory approvals with respect to other investors in the Company, which regulatory approvals were obtained prior to June 30, 2002, if the votes conferred by Common Shares and Preference A Shares beneficially owned by a person otherwise would have represented more than 9.9% of the voting power of all shares of the Company entitled to vote generally at an election of the Company's directors, the vote of each Preference A Share held by that person would have been reduced by whatever amount was necessary so that after any reduction, the votes conferred by the Common Shares and the Preference A Shares beneficially owned by that person would have constituted 9.9% of the total voting power of all shares of the Company entitled to vote generally at any election of directors. Each Preference A Share is convertible at any time into one Common Share, subject to certain adjustments set forth in the Preference A Certificate. The Preference A Shares will automatically convert into Common Shares following the later of (i) the Company's receipt of certain regulatory approvals and (ii) 90 days following the consummation of the purchase price adjustment to be performed at November 20, 2005 as set forth in Section B of the Subscription Agreement (as defined hereafter). Notwithstanding the foregoing, prior to the receipt of certain shareholders approvals, which were obtained on March 7, 2002, Section 5.3 of the Shareholders Agreement (as defined hereafter) imposed certain restrictions on the conversion of Preference A Shares, including that holders of Preference A Shares were not allowed to convert any Preference A Shares issued under the Subscription Agreement (as defined hereafter) unless all necessary approvals for the ownership of Common Shares issued upon such conversion were obtained. The Preference A Shares are entitled to certain dividend rights and liquidation preferences as set forth in the Preference A Certificate. Warrants Each Warrant entitles the holder to purchase one Common Share. The number and character of such Common Share are subject to certain adjustments set forth in the Warrant. The exercise price of each Warrant is $20.00 per Common Share, subject to certain adjustments set forth in the Warrant. Notwithstanding the foregoing, Section 5.3 of the Shareholders Agreement (as defined hereafter) provides that, prior to the receipt of certain regulatory approvals, the holders of Warrants may not exercise any Warrants issued under the Subscription Agreement (as defined hereafter) unless all necessary approvals for the ownership of Common Shares issued upon such exercise have been obtained. The Warrants will expire on September 19, 2002. Holders of the Warrants may exercise their purchase rights under the Warrant by making payment of the purchase price in cash or through a cashless exercise. On April 19, 2002, (i) Trident II exercised its Warrant to purchase 163,971 Common Shares in a cashless exercise resulting in the issuance of 51,931 Common Shares to Trident II, (ii) Trident ESC exercised its Warrant to purchase 4,616 Common Shares in a cashless exercise resulting in the issuance of 1,462 Common Shares to Trident ESC, and (iii) Trident PF exercised its Warrant to purchase 4,591 Common Shares in a cashless exercise resulting in the issuance of 1,454 Common Shares to Trident PF. In connection with the acquisition of the Preference A Shares and the Warrants, the Partnerships entered into the following agreements. Assignment Agreement On November 8, 2001, the Partnerships entered into an agreement (the "Assignment Agreement") with the Company, Warburg Pincus Private Equity VIII, L.P. Warburg Pincus International Partners, L.P., Warburg Pincus Netherlands Internationale Partners I, C.V. and Warburg Pincus Netherlands International Partners II, C.V. (collectively, "Warburg"), HFCP IV (Bermuda), L.P. ("H&F"), The Trident Partnership, L.P. ("Trident I") and MMRCH. Under the Assignment Agreement, Warburg assigned to the Partnerships the right and obligation to purchase an aggregate of $35,000,000 of Preference A Shares and Warrants on the terms and conditions set forth in the Subscription Agreement (as defined hereafter). Although each of the Partnerships became a "Purchaser" under the Subscription Agreement, the Assignment Agreement limits certain rights that the Partnerships have as "Purchasers" under the Subscription Agreement. For example, the Assignment Agreement provides among other limitations that, subject to certain exceptions, (i) Warburg and H&F have the sole right to make any determinations and to take any actions with respect to the purchase price adjustments set forth in Section B of the Subscription Agreement and (ii) the consent of the Partnerships is not required to effect any modification, amendment or waiver of any provision of the Subscription Agreement. Similarly, the Assignment Agreement also limits certain rights that the Partnerships have as "Investors" under the Shareholders Agreement (as defined hereafter). The Assignment Agreement provides that, subject to certain exceptions, Warburg and H&F may consent on behalf of all other "Investors" (as defined in the Shareholders Agreement) to any amendment or modification of any section of the Shareholders Agreement. Also pursuant to the Assignment Agreement, the parties confirmed the termination of the right of MMRCH to have an observer attend meetings of the Board of Directors of the Company and the right of Trident I to designate a director for election to the Board of Directors of the Company. The Company was released from its obligation to make any further capital contributions to Trident II pursuant to an existing capital commitment, other than with respect to an outstanding capital call for which the Company funded approximately $4.7 million. On November 20, 2002, all of MMRCH's 905,397 Class A Warrants were canceled in exchange for the issuance by the Company of 140,380 Common Shares, and all of MMRCH's 1,770, 601 Class B Warrants were canceled in exchange for a cash payment by the Company of $7.50 per Class B Warrant (approximately $13.3 million in the aggregate). Subscription Agreement The Partnerships are also parties to the Subscription Agreement, dated as of October 24, 2001, as amended as of November 20, 2001, January 3, 2002 and March 15, 2002 (the "Subscription Agreement"), by and between the Company, Warburg and H&F and the other parties thereto (the Partnerships, Warburg, H&F and the other purchasers are collectively, the "Purchasers"). Under the Subscription Agreement, the Partnerships acquired an aggregate of 1,636,729 Preference A Shares and 173,178 Warrants. The purchase price paid by the Partnerships for the Preference A Shares and the Warrants was $34,999,961.47. The Subscription Agreement provides for certain purchase price adjustments. Each purchase price adjustment may result in, among other things, the Company issuing to each of the Purchasers additional Preference A Shares. Section D.1(f) of the Subscription Agreement provides that the Purchasers (as defined in the Subscription Agreement) may not transfer, in one transaction, or a series of related transactions, to a single person or group, the Common Shares, and/or securities convertible into Common Shares, representing in excess of either 51% of the votes then entitled to be cast in election of the Company's directors, or 51% of the then outstanding Common Shares, without making available to all holders of Common Shares the right to participate in such transaction on substantially the same terms. Section E of the Subscription Agreement provides that the Company is required to form a new, wholly-owned subsidiary ("Newco") to hold the Company's equity interest in Arch Reinsurance Ltd., a Bermuda company, and all of the Company's core insurance operations other than Arch Reinsurance Company, a Nebraska corporation, in each case, no later than 90 days after November 20, 2001. Newco is required to be a company organized under the laws of Bermuda, with a number and kind of authorized and outstanding capital shares (including shares and warrants identical to the Preference A Shares and the Warrants) that replicate, as nearly as possible, those of the Company. Section E.3 of the Subscription Agreement provides that if (i) the Company fails to obtain certain regulatory approvals before May 20, 2002 or (ii) the "Adjustment Basket" determined under Section B of the Subscription Agreement is less than zero and its absolute value exceeds $250.0 million, then the Preference A Shares and Warrants may be exchanged by each Purchaser, in whole or in part (but not for less than the $150.0 million liquidation preference of the Preference A Shares), for preference shares and warrants of Newco bearing identical rights and privileges, including the right to convert into, or be exercised for, common shares of Newco. Section F.5 of the Subscription Agreement provides that, until the date of the final determination of the "Adjustment Basket" at November 20, 2005, the transaction committee's approval of (i) an amendment, modification or waiver of rights under the Subscription Agreement, the Certificate of Designations of the Preference A Shares, the Warrants or the Shareholders Agreement, (ii) the enforcement of obligations of the Purchasers under the above agreements or (iii) any actions relating to the disposition of the Company's non-core assets shall be deemed approved by the Company's board of directors. Shareholders Agreement The Partnerships are also parties to the Shareholders Agreement, dated as of November 20, 2001, as amended on January 3, 2002 and March 15, 2002 (the "Shareholders Agreement"), by and among the Company, Warburg, and H&F, H&F International Partners IV-A (Bermuda), L.P., H&F International Partners IV-B (Bermuda), L.P., H&F Executive Fund IV (Bermuda), L.P. (collectively, "H&F Investors") and the other persons parties thereto (the Partnerships, Warburg, the H&F Investors and the other persons are collectively, the "Investors"). Section 3.1 of the Shareholders Agreement provides that Warburg and the H&F Investors have the right to appoint or have nominated a certain number of directors to the Company's board of directors. In addition, Section 3.3 of the Shareholders Agreement provides that, prior to the Company's receipt of certain regulatory approvals and subject to certain exceptions, the Company may not take certain actions without the approval of at least one director representing Warburg and one director representing the H&F Investors. Section 3.4 of the Shareholders Agreement required each of the Partnerships to vote all their voting securities of the Company in favor of (i) the proposals to be submitted for approval of the shareholders of the Company at the special general meeting of the Company's shareholders to be held in connection with the transactions contemplated by the Subscription Agreement and the Shareholders Agreement and (ii) the proposals, to be submitted for approval of the Company's shareholders at their 2002 annual general meeting, to approve the grant of restricted shares to Robert Clements and an option grant to John M. Pasquesi. Section 4 of the Shareholders Agreement grants to Warburg and the H&F Investors demand registration rights and grants to the other Investors piggy-back registration rights. If at any time the Company proposes to register any Common Shares on its own behalf or on behalf of any of its shareholders (including pursuant to Warburg's or H&F Investors' demand registration rights), the Company is required to, pursuant to the terms of the Shareholders Agreement, include the Common Shares held by the Partnerships and certain other investors who elect to have such shares included. Section 5 of the Shareholders Agreement provides that, in the event that Warburg, H&F Investors, Insurance Private Equity Investors, L.L.C. or Orbital Holdings, Ltd. proposes to transfer Preference A Shares, Warrants or Common Shares issued upon conversion or exercise of such securities to a third party and the net proceeds of such sale are reasonably expected to exceed $50.0 million, the other Investors may have rights to "tag along" in such sale and to participate ratably on the basis of securities owned in such a third party sale on the same terms as the selling investor. In addition, Section 5 of the Shareholders Agreement provides that, under certain circumstances, Warburg and H&F Investors have drag-along rights with respect to the Partnerships. Under Section 5.2 of the Shareholders Agreement, Warburg, the H&F Investors, the Partnerships and certain other parties thereto agreed not to sell more than one third (1/3) of the shares each Investor purchased in its original investment until the earliest to occur of (i)~November 20, 2002, (ii) any event that would cause the Company's outstanding Class B Warrants to vest and/or become exercisable or (iii) the completion by the Company of a registered public offering of Common Shares the net proceeds to the Company of which exceed $25.0 million. The Company consummated an offering of the type contemplated by clause (iii) in the first half of 2002. Prior to the receipt of certain shareholders approvals, which were obtained on March 7, 2002, Section 5.3 of the Shareholders Agreement imposed certain restrictions on the conversion of Preference A Shares, including that holders of Preference A Shares were not allowed to convert any Preference A Shares issued under the Subscription Agreement unless all necessary approvals for the ownership of Common Shares issued upon such conversion were obtained.
