Each capitalized term used but not defined in this Agreement shall have the meaning provided for such term in the Merger Agreement (as defined below). WHEREAS, Washington Mutual and Bank United Corp. have entered into an Agreement and Plan of Merger (the "Merger Agreement") dated as of August 18, 2000, pursuant to which Bank United Corp. will be merged with and into Washington Mutual (the "Merger"). Washington Mutual will be the surviving entity following the Merger. As a result of the Merger, the Bank will become an indirect subsidiary of Washington Mutual.

WHEREAS, Washington Mutual desires that the Bank issue a redemption notice for the shares of Series A Stock and the shares of Series B Stock and redeem such shares except to the extent such shares are owned by Washington Mutual as of the date of redemption and Washington Mutual further desires to offer to acquire all the shares of the Series A Stock and the Series B Stock prior to the closing of the Merger. NOW THEREFORE, in consideration of the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, WASHINGTON MUTUAL, BANK UNITED CORP. AND THE BANK AGREE AS FOLLOWS: 1. Redemption of Preferred Stock. Bank United Corp. and the Bank ----------------------------- will take all steps necessary to effect the redemption (the "Redemption") of all of the shares of Series A Stock and all of the shares of Series B Stock, other than shares of Series A Stock and shares of Series B Stock owned by Washington Mutual on the date of the redemption (the "Redemption Date"), pursuant to the terms of the Certificate of Designations, Powers, Preferences and Right of the Series A Stock (the "Series A Certificate") and the Certificate of Designations, Powers, Preferences and Right of the Series B Stock (the "Series B Certificate"), respectively, as well as the further terms set forth in this Agreement. The redemption of the Series A Stock will be made pursuant to Section 5(a) of the Series A Certificate and shall be at a redemption price (the "Series A Redemption Price") of $25.50 plus accrued and unpaid dividends thereon from the dividend payment date immediately preceding the Redemption Date. The redemption of the Series B Stock will be made pursuant to Section 5(a) of the Series B Certificate and shall be at a redemption price (the "Series B Redemption Price") of $26.25 plus accrued and unpaid dividends thereon from the dividend payment date immediately preceding the Redemption Date. 2. Washington Mutual Tender Offer. ------------------------------ (a) On or about the date the Bank issues notices of redemption to the holders of shares of Series A Stock and Series B Stock in connection with the Redemption, Washington Mutual may, at its sole option, elect to initiate a cash tender offer (the "Tender Offer") for all of the shares of the Series A Stock and for all of the shares of the Series B Stock, in each case at a price per share to be determined by Washington Mutual. Bank United Corp. and the Bank agree that Washington Mutual may elect to condition the closing of the Tender Offer on the receipt of at least 90% of the aggregate shares of Series A Stock and Series B Stock and other customary and reasonable conditions. (b) The Bank agrees to take reasonable steps to assist Washington Mutual in effecting the Tender Offer, including but not limited to: (i) providing Washington Mutual, or causing its agents to provide Washington Mutual, with any stockholder information reasonably requested by Washington Mutual, (ii) issuing a formal recommendation (the "Recommendation") that the holders of the Series A Stock and Series B Stock accept the Tender Offer, and (iii) making the Recommendation sufficiently in advance of the commencement of the Tender Offer to allow the Recommendation to be included in the tender offer materials and publications. 3. New Stock. --------- (a) If any shares of Series A Stock are redeemed pursuant to this Agreement (such shares, the "Series A Redeemed Shares"), Bank United Corp. may create a new series of preferred stock (the "New Series-1 Stock") to be issued to Washington Mutual as herein provided. The New Series-1 Stock will have substantially the same terms, rights and privileges, including without limitation the liquidation preference as the Series A Stock, except that (i) Bank United Corp. will be permitted to redeem some or all of the shares of New Series-1 Stock at any time after the date of issuance at 100% of the New Series-1 Stock liquidation preference plus 100% of accrued but unpaid dividends and (ii) in the event that the ability of Bank United to pay dividends in accordance with 12 C.F.R. Part 563, Subpart E (or any successor provision thereto) as a result of the Redemption and the other transactions contemplated hereby is restricted, appropriate adjustments shall be deemed made to the terms of the New Series-1 Stock in order to permit Bank United Corp. to pay regular quarterly dividends on its common stock without regard to the preferences of the New Series-1 Stock to receive dividend payments thereon, and the failure of the Bank to pay dividends with respect to the New Series-1 Stock as a result of such restrictions shall not result in any right of the holders of the New Series-1 Stock to elect any directors to the board of directors of the Bank. Washington Mutual agrees to purchase from Bank United Corp. and Bank United Corp. agrees to sell to Washington Mutual, substantially concurrently with the Redemption, if Bank United Corp. elects to create the New Series-1 Stock, the number of shares of New Series-1 Stock equal to the number of Series A Redeemed Shares at a purchase price per share of $25.00. (b) If any shares of Series B Stock are redeemed pursuant to this Agreement (such shares, the "Series B Redeemed Shares"), Bank United Corp. may create a new series of preferred stock (the "New Series-2 Stock") to be issued to Washington Mutual as herein provided. The New Series-2 Stock will have substantially the same terms, rights and privileges, including without limitation the liquidation preference as the Series B Stock, except that (i) Bank United Corp. will be permitted to redeem some or all of the shares of New Series-2 Stock at any time after the date of issuance at 100% of the New Series-2 Stock liquidation preference plus 100% of accrued but unpaid dividends and (ii) in the event that the ability of Bank United to pay dividends in accordance with 12 C.F.R. Part 563, Subpart E (or any successor provision thereto) as a result of the Redemption and the other transactions contemplated hereby is restricted, appropriate adjustments shall be deemed made to the terms of the New Series-2 Stock in order to permit Bank United Corp. to pay regular quarterly dividends on its common stock without regard to the preferences of the New Series-2 Stock to receive dividend payments thereon, and the failure of the Bank to pay dividends with respect to the New Series-2 Stock as a result of such restrictions shall not result in any right of the holders of the New Series-2 Stock to elect any directors to the board of directors of the Bank. Washington Mutual agrees to purchase from Bank United Corp. and Bank United Corp. agrees to sell to Washington Mutual, substantially concurrently with the Redemption, if Bank -2- United Corp. elects to create the New Series-2 Stock, the number of shares of New Series-2 Stock equal to the number of Series B Redeemed Shares at a purchase price per share of $25.00. 4.
