The Executive has carefully considered other alternatives to the execution and delivery of this Agreement, and has decided to sign this Agreement and to be bound by its terms, including, without limitation, the Release, in order to secure the benefits provided under this Agreement.

6.3 The Executive acknowledges that he may have claims against the Company, the Bank and the other BankUnited Beneficiaries of which he has no knowledge. The Executive acknowledges and agrees that the Release is specifically intended to, and does, extend to any and all such claims whether known, claimed, suspected or unknown.

The Company and the Bank will return to the Executive all of his personal property that remains in their possession or control (the “Executive Property”).

9. Non-Solicitation of Employees; Confidential Information.

9.1 For a period of one (1) year following the Effective Date (the “Restricted Period”), the Executive shall not, for his own account or jointly with another, directly or indirectly, for or on behalf of any individual, partnership, corporation, or other legal entity, as principal, agent or otherwise, solicit or induce, or in any manner attempt to solicit, any person employed by any member of the BankUnited Group to leave such employment, whether or not such employment is pursuant to a written contract and whether or not such employment is at will. The restrictions in this Section 9.1 shall not apply with respect to the Executive’s two administrative assistants.

10.19 Section 409A. The Agreement is intended to comply with the requirements of Section 409A of the Code or an exemption or exclusion therefrom and shall in all respects be administered in accordance with Section 409A of the Code. Without limiting the generality of the foregoing, the Company, the Bank and the Executive agree that the payments contemplated by Section 3.1 are not intended to constitute “deferred compensation” within the meaning of Section 409A and the Company, and the Bank and the Executive agree to report and withhold with respect to such amount consistent with such intent. Within the time period permitted by the applicable Treasury Regulations, the Company shall, in consultation with Executive, modify the Agreement, in the least restrictive manner necessary and without any diminution in the value of the payments to Executive (or increase in liability or cost to the Company), in order to cause the provisions of the Agreement to comply with the requirements of Section 409A of the Code, so as to avoid the imposition of taxes and penalties on Executive pursuant to Section 409A of the Code; provided, any such amendment shall be subject to approval of the OTS and the FDIC to the extent required under applicable law. Notwithstanding anything in this Agreement to the contrary, if any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable under this Agreement by reason of Executive’s separation from service during a period in which he is a Specified Employee (as defined below), then subject to any permissible acceleration of payment by the Company under Treas. Reg. Section 1.409A 3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest) or (j)(4)(vi) (payment of employment taxes):

(i) if the payment or distribution is payable in a lump sum, Executive’s right to receive payment or distribution of such non-exempt deferred compensation will be delayed until the earlier of Executive’s death or January 2, 2009 (the “Delayed Payment Date”); and

(ii) if the payment or distribution is payable over time, the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following Executive’s separation from service will be accumulated and Executive’s right to receive payment or distribution of such accumulated amount will be delayed until the Delayed Payment Date, whereupon the accumulated amount will be paid or distributed to Executive and the normal payment or distribution schedule for any remaining payments or distributions will resume.

10

All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A of the Code, including, without limitation, that (i) in no event shall reimbursements by the Company under this Agreement be made later than the end of the calendar year next following the calendar year in which the applicable fees and expenses were incurred, provided, that the Executive shall have submitted an invoice for such fees and expenses at least 10 days before the end of the calendar year next following the calendar year in which such fees and expenses were incurred; (ii) the amount of in-kind benefits that the Company is obligated to pay or provide in any given calendar year shall not affect the in-kind benefits that the Company is obligated to pay or provide in any other calendar year; (iii) the Executive’s right to have the Company pay or provide such reimbursements and in-kind benefits may not be liquidated or exchanged for any other benefit; and (iv) in no event shall the Company’s obligations to make such reimbursements or to provide such in-kind benefits apply later than the Executive’s remaining lifetime (or if longer, through the 20th anniversary of the Effective Date). For purposes of this Agreement, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder (“Final 409A Regulations”), provided, however, that, as permitted in the Final 409A Regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Board of Directors or a committee thereof, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Agreement.

10.20 Insurance and Indemnification. For six (6) years after the Effective Date, the Bank and the Company shall each cause the Executive to continue to be covered by and named as an insured under any policy or contract of insurance obtained by it to insure its directors and officers against personal liability for acts or omissions in connection with service as an officer or director of the Bank and the Company or service in other capacities at the request of the Bank and the Company, respectively. The coverage provided to the Executive pursuant to this Section 10.20 shall be of the same scope and on the same terms and conditions as the coverage (if any) provided to other officers or directors of the Bank and the Company, respectively.

10.21 JURY TRIAL WAIVER. THE PARTIES HERETO HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY AND ALL RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION (INCLUDING, BUT NOT LIMITED TO, ANY CLAIMS, CROSSCLAIMS OR THIRD PARTY CLAIMS) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT. THE PARTIES HEREBY CERTIFY THAT NO REPRESENTATIVE OR AGENT OF THE OTHER PARTIES HAS REPRESENTED EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF SUCH LITIGATION, SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION.
