Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in the Fiscal Year

On September 9, 2008, the Board of Directors of BankUnited Financial Corporation (the “Company”) approved amendments to Article Ten of the Company’s Bylaws. The amendments modify the indemnification and insurance provisions of Article Ten to require Board approval for the indemnification and purchase of insurance protection for agents, add provisions regarding rights of contract, amendment and severability and define various terms used in the Bylaws. The Bylaws previously provided for indemnification and insurance protection for agents of the Company in the same manner as it did for directors, officers and employees. Under the amended Bylaws, persons acting as agents of the Company may be indemnified if the Board of Directors deems such indemnification to be appropriate because such persons acted in good faith and in the best interests of the Company. The Board of Directors may also purchase insurance protection for agents if it deems such action to be appropriate. In addition, a new provision of Article Ten of the Bylaws establishes that the rights to indemnification and insurance from the Company are contractual rights that survive the termination of such person’s service as director, officer, employee or agent of the Company and inure to the benefit of heirs, executors and administrators of such person. These amendments to the Bylaws became effective on September 9, 2008.

This summary of the amendments to the Bylaws is qualified in its entirety by reference to the Amended Bylaws, a copy of which is filed as exhibit 3.1 to this Report and incorporated herein by reference.
