Item 3. Source and Amount of Funds or Other Consideration.

In March 2014, in connection with the formation of the Issuer, Arch Re Bermuda purchased 2,500,000 common shares of the Issuer and Gulf Re purchased 600,000 preference shares of the Issuer (of which, 458,015 preference shares were redeemed by the Issuer in August 2019 pursuant to a pro rata redemption of the outstanding

preference shares). Pursuant to an Agreement and Plan of Merger dated as of October 9, 2020 (as amended by Amendment No. 1, dated November 2, 2020, the “Merger Agreement”) by and among Arch, the Issuer and Greysbridge Ltd., a Bermuda exempted company limited by shares and a wholly owned subsidiary of Arch, Arch agreed to acquire all of the common shares of the Issuer not already owned by Arch Re Bermuda at a cash purchase price of $35.00 per common share. In connection with the transactions contemplated by the Merger Agreement, the Issuer, Arch Re Bermuda and Gulf Re have entered into a Voting and Support Agreement dated October 9, 2020, pursuant to which, among other things, each of Arch Re Bermuda and Gulf Re agreed to vote the common shares held by it in favor of the merger. On November 2, 2020, pursuant to an assignment and assumption agreement between Arch and Greysbridge Holdings Ltd., a Bermuda exempted company limited by shares and a wholly owned subsidiary of Arch (“Holdco”), Arch assigned its rights under the Merger Agreement to Holdco.

On February 16, 2021, (i) Arch Re Bermuda sold 230,400 common shares in the aggregate to Kelso Investment Associates X, L.P. (“KIA”), KEP X, LLC and KSN Fund X, L.P. (together, the “Kelso Funds”) pursuant to a purchase agreement among the Kelso Funds and Arch Re Bermuda and (ii) Arch Re Bermuda sold 230,400 common shares to WP Windstar Investments Ltd. (“WP Windstar”) pursuant to a purchase agreement between WP Windstar and Arch Re Bermuda. The foregoing sales are referred to herein as the “Co-Investor Transfers”. In connection with the Co-Investor Transfers, (i) the Kelso Funds entered into a Voting and Support Agreement with the Issuer pursuant to which, among other things, each of the Kelso Funds agreed to vote the common shares held by it in favor of the merger, and (ii) WP Windstar entered into Voting and Support Agreement with the Issuer pursuant to which, among other things, WP Windstar agreed to vote the common shares held by it in favor of the merger.

To enable Holdco to fund payment of the cash merger consideration, Holdco has obtained equity commitments as follows: (i) pursuant to an equity commitment letter among Holdco and the Kelso Funds, the Kelso Funds have committed to make an aggregate cash contribution of up to $201,936,000 and to contribute to Holdco the 230,400 common shares of the Issuer owned by the Kelso Funds, (ii) pursuant to an equity commitment letter among Holdco, certain funds managed by Warburg Pincus LLC (“Warburg Pincus”) and WP Windstar, such funds have committed to make an aggregate cash contribution of up $201,936,000 and WP Windstar has committed to contribute to Holdco the 230,400 common shares of the Issuer owned by WP Windstar, and (iii) pursuant to an equity commitment letter between Holdco and Arch Re Bermuda, Arch Re Bermuda has committed to make a cash contribution of up to $208,628,000 and to contribute to Holdco the 2,039,200 common shares of the Issuer owned by Arch Re Bermuda (collectively, the “Equity Financing”). The source of funds for Holdco’s payment of the cash merger consideration will be the Equity Financing. The source of funds for Arch Re Bermuda’s cash commitment in respect of the Equity Financing will be working capital. Upon consummation of the Equity Financing, Arch Re Bermuda will own 40% of Holdco, the Kelso Funds will own 30% of Holdco, and funds managed by Warburg Pincus will own 30% of Holdco. Upon consummation of the merger pursuant to the Merger Agreement, Holdco will be the sole shareholder of the Issuer.

In connection with the foregoing, (i) Holdco, Arch Re Bermuda, KIA and WP Windstar have entered into an interim investors agreement pursuant to which such parties have agreed, in relevant part, to vote all shares of any voting securities of the Issuer owned by them in favor of the merger, not to transfer any equity interests of the Issuer that each party holds directly or indirectly without the other parties’ consent and to share certain expenses incurred in connection with the merger, and (ii) Arch, Kelso and Warburg Pincus have entered into a participant agreement pursuant to which such parties have agreed to share certain expenses incurred in connection with the merger.

Item 4. Purpose of Transaction.

The purpose of the merger is to enable Holdco to acquire all of the common shares of Watford so that Holdco can operate Watford as a privately held company while retaining access to Watford’s underwriting platform and its licenses in Bermuda, the United States and Europe. The purpose of the Co-Investor Transfers is to enable the common shares transferred to be voted by the transferees in favor of the merger.

Other than as described in Item 3 above (which information is incorporated herein by reference) and below, the Reporting Persons do not have any plans or proposals that relate to or would result in: (a) an extraordinary transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (b) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (c) any material change in the

present dividend rate or policy, or indebtedness or capitalization of Watford; (d) any change in the present board of directors or management of the Issuer, including, but not limited to, any plans or proposals to change the number or the term of directors or to fill any existing vacancies on the board; (e) any other material change in the Issuer’s corporate structure or business or changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (f) any class of equity securities of the Issuer to be delisted from a national securities exchange; or (g) any class of equity securities of the Issuer becoming eligible for termination of registration pursuant to section 12(g)(4) of the Act.

–Dividend rate or policy, or indebtedness or capitalization. After the merger, the Issuer’s dividend policy with respect to its common shares will be determined by the board of the surviving company and the surviving company’s sole shareholder which will be Holdco. Holders of the Issuer’s preference shares will be entitled to the same dividend and other relative rights, preferences, limitations and restrictions after the merger as are applied to the preference shares prior to the merger.

–Board of directors; management. At the effective time of the merger, the director(s) of Greysbridge Ltd. immediately prior to the effective time will become the initial director(s) of the surviving company.

–Delisting and deregistration of the Issuer’s equity securities. After the merger, the Reporting Persons expect that the Issuer’s common shares will be delisted from the Nasdaq Global Select Market, and the registration of the common shares under the Exchange Act will be terminated pursuant to Section 12(g)(4) of the Exchange Act. The Issuer’s preference shares will remain outstanding and, so long as the preference shares remain outstanding, the Issuer will remain obligated to file reports under the Exchange Act. If the Issuer’s outstanding preference shares are redeemed, the Reporting Persons expect that the Issuer’s preference shares thereafter would be delisted from the Nasdaq Global Select Market, and registration of the preference shares under the Exchange Act would be terminated pursuant to Section 12(g)(4) of the Exchange Act.
