Item 8.01               Other Events.

On June 2, 2011, BankUnited, Inc. (the “Company”) and Herald National Bank (“Herald”) issued a joint press release announcing the execution of a Merger Agreement, dated as of June 2, 2011, between the Company and Herald.  A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

As previously disclosed, John A. Kanas, the Company’s Chairman, President and Chief Executive Officer, and John Bohlsen, the Company’s Vice Chairman and Chief Lending Officer and a director, are subject to non-compete agreements which expire in August 2012.  These agreements purport to restrict Messrs. Kanas and Bohlsen in their individual capacities from engaging in the consumer and commercial banking businesses in New York.  Until the expiration of these agreements, it is the Company’s expectation that Herald will not be merged with, and will be held separately from, BankUnited, the Company’s wholly owned thrift subsidiary.  During that period, neither Mr. Kanas nor Mr. Bohlsen will be an officer, director or employee of Herald, nor will they have any decision-making authority with respect to or otherwise participate in the affairs of Herald.  Until the expiration of Messrs. Kanas’s and Bohlsen’s non-compete agreements, Herald’s management will report to Rajinder P. Singh, the Company’s Chief Operating Officer, who will report to Herald’s board of directors.  It is expected that Herald will be merged into BankUnited at the end of August 2012.
