2.2 Position and Duties of Executive.

During the Term of employment, the Executive shall diligently perform all services as may be reasonably assigned to him by the Company’s CEO, Board or its Chairman and shall exercise such power and authority as may from time to time be delegated to him by the CEO, Board or its Chairman. The Executive shall be required to report solely to, and shall be subject solely to the supervision and direction of, the Company’s CEO, Board or its Chairman and no other person or group shall be given authority to supervise or direct the Executive in the performance of his duties. The Executive shall devote substantially all his working time and attention (other than during weekends, holidays, approved vacation periods, and periods of illness or approved leaves of absence) to the business and affairs of the Company, render such services efficiently and to the best of his ability, and use his best efforts to promote the interests of the Company.

2.3 Place of Performance. In connection with his employment by the Company, the Executive’s principal place of employment shall be the Company’s executive offices in Florida.

3. Compensation.

3.1 Base Salary. The Executive shall receive a base salary of $650,000 (the “Base Salary”) per year during the Term of this Agreement, with such Base Salary payable in installments consistent with the Company’s standard payroll practice for executives. Prior to each anniversary of the Commencement Date occurring during the Term, the Compensation Committee of the Board of Directors (the “Committee”) shall review the Executive’s annual rate of salary, and may, in its discretion, approve an increase therein. The first and last year shall be prorated based on the number of months in such year. In addition to salary, the Executive may receive other cash or stock compensation from the Company for services rendered hereunder at such times, in such amounts and on such terms and conditions as the Committee, in its discretion, may determine from time to time continuing throughout the Term. The Base Salary shall not be decreased unless the Executive is not performing his duties and responsibilities in all material respects to the satisfaction of the Board. Any increase in Base Salary shall not limit or reduce any obligation to the Executive under this Agreement. The Executive shall not separately receive directors’ fees. All disputes as to Base Salary shall be resolved by Arbitration as provided in paragraph 24.

3.2 Annual Bonus. The Executive may be entitled to a cash bonus (the “Annual Bonus”) for each fiscal year, or part thereof, occurring during the Term. The Annual Bonus for a year shall be based upon merit during such year, taking into account any performance goals set in advance by the Committee for such bonus, and shall be determined, after recommendation by the Chairman, by the Committee (or the independent members of the Board in the absence of the Committee or a replacement therefor) in their sole discretion. The range of Annual Bonus shall be performance-based determined in accordance with the standard practices of the Committee.

4. Additional Benefits.

4.1 Expense Reimbursement. During the Term, upon the submission of supporting documentation by the Executive in form sufficient to permit deduction thereof under applicable tax law (but without regard to actual deductibility), the Company shall promptly reimburse the Executive for all reasonable expenses actually paid or incurred by the Executive in the course of and pursuant to the business of the Company, including expenses for entertainment and all travel and living expenses while away from home on business or at the request of the Company, provided that such expenses are incurred and accounted for in accordance with the Company’s regular policies and procedures.

4.2 Other Benefits. The Company shall provide the Executive the standard benefits provided to other senior executives, including, major medical and hospitalization insurance coverage, and group disability and group life insurance for the Executive (collectively, the “Policies”), which Policies the Company shall keep in effect at its sole expense throughout the Term. To the extent any Policies have an eligibility period, Executive may maintain his existing equivalent coverage under COBRA and the Company shall reimburse him for that expense until the eligibility period is satisfied. In addition to the group disability insurance coverage provided by the Company to its executive employees, the Company shall pay to the Executive $5,000 annually to reimburse him for the cost (or a portion of the cost) of an individual disability policy for a term extending throughout the Term of this Agreement, without deduction for any payments provided under the Company’s group disability insurance coverage. In addition to group life insurance, the Company shall maintain on the life of the Executive term life insurance policy extending throughout the Term of this Agreement in the amount of $2,500,000, the beneficiary of which shall be designated by the Executive. If the life insurance policy is portable and fully transferable, the Company agrees to make reasonable efforts to have the policy transferred to the Executive upon his termination, at which time the Executive will be fully responsible for all premiums and maintenance of such policy. The Executive represents to the Company that he is a “healthy, non-smoker.” The Executive understands that the Company’s obligation to purchase the life insurance policy described above ceases if the Executive’s representation is false or misleading. Nothing paid to the Executive under any plan or arrangement presently in effect or made available in the future shall be deemed to be in lieu of the Base Salary or Annual Bonus payable to the Executive pursuant to this Agreement.

4.3 Automobile Allowance. During the Term, the Company shall provide Executive with an automobile allowance of six hundred dollars ($600) per month, which amount is intended to compensate Executive for wear and tear and reimburse the Executive for all costs of gasoline, oil, repairs, maintenance, insurance and other expenses incurred by Executive by reason of the use of Executive’s automobile for Company business from time to time. The amount of this allowance will be reviewed by the Company and the Executive from time to time and increased prospectively as is necessary to compensate and reimburse the Executive for such wear and tear and costs.

4

4.4 Vacation. The Executive shall be entitled to four (4) weeks vacation per year, said vacation to be scheduled so as not to materially interfere with the performance by the Executive of his duties pursuant to this Agreement.

4.5 Club Membership. The Company shall pay the annual dues for the Executive’s membership at La Gorce Country Club and Riviera Country Club, and such luncheon clubs as he deems appropriate for the discharge of his duties hereunder. The membership at LaGorce Country Club shall be the property of the Company, and be in the Company’s name if possible.

4.6 Working Facilities and Support Staff. The Company shall furnish the Executive with an office or offices of a size and with furnishings and other appointments, and secretarial and such other facilities and support services suitable to his position and adequate for the performance of his duties hereunder including, but not limited to, appropriate internet and news service subscriptions, cellular telephones, computers (“palm,” “lap top” or other appropriate computer/cellular devices).

4.7 Securities Grants.

a) On August 21, 2006, the Committee shall grant the Executive a number of shares of the Company’s Class A Common Stock (or equivalent or comparable rights to receive such stock, including, without limitation, in the form of deferred stock, restricted stock units or deferred stock units), having a value on the date of such grant of $375,000 based on the closing price of the Class A Common Stock as of the date of grant, ownership of such stock or units to vest in equal amounts over five years from the date of grant. (As the grant vests, the stock or units shall become “Vested Benefits” for purposes of this Agreement.) The Company at its election may satisfy these grants with an equivalent cash payment.

b) The shares or rights granted pursuant to subparagraph (a) shall not be delivered to the Executive, but rather delivery shall be delayed in accordance with a deferral agreement entered into between the Executive and the Company and consistent with the requirements of Code Section 409A. Among other provisions, the deferral agreement shall contain provisions that the Executive shall receive a complete distribution of the deferred property within thirty (30) days following any of the following: the Executive’s termination under Sections 5.2 or 5.3, or an event which is a Change of Control as defined in the deferral agreement. The Company may utilize a “rabbi trust” to hold assets to satisfy its obligation to the Executive with respect to the deferred shares or rights, subject to the claims of the Company’s creditors in the event of its insolvency.

c)(i) In the event of a Change of Control, all grants previously not vested shall become fully vested and if any grant has not been made as provided in (a) above there shall be granted to the Executive a sufficient number of shares or rights to satisfy the requirements of such provisions based on the closing price bid of the Class A Common Stock on the date of the grant.

5

(ii) In the event this Agreement terminates under Section 5.3 (Termination Without Cause) or under Section 5.2 as a result of disability, all grants previously not vested shall continue to vest in accordance with the vesting schedule provided in (a) above, and if any grant has not been made as provided in (a) above, there shall continue to be granted to the Executive a sufficient number of shares or rights to satisfy the requirements of such provision based on the closing price bid of the Class A Common Stock on the date of the grant which shall continue to vest in accordance with the vesting schedule provided in (a) above. The Company, at its election, may satisfy one or more the grants with an equivalent cash payment.

(iii) In the event this Agreement terminates under Section 5.2 as a result of death, all grants not vested as of the date of death shall lapse and no further grants shall be made to satisfy the provision of subsection (a).

4.8 Indemnification and Insurance.

(a) During the Term of this Agreement, the Company shall cause the Executive 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 Company or service in other capacities at the request of the Company. The coverage provided to the Executive pursuant to this section 4.8 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 Company.

(b) To the maximum extent permitted under applicable law, during the Term of this Agreement and for a period of 3 years thereafter, the Company shall indemnify the Executive against and hold him harmless from any costs, liabilities, losses and exposures to the fullest extent and on the most favorable terms and conditions that similar indemnification is offered to any director or officer of the Company or any subsidiary or affiliate thereof.

5. Termination.

5.1 Termination for Cause. Notwithstanding anything contained herein to the contrary, this Agreement may be terminated by the Company for Cause. As used in this Agreement, “Cause” shall mean (i) any action or omission or failure of the Executive which constitutes a material breach of this Agreement, including without limitation failing to carry out his duties and responsibilities in accordance with Section 2.2 (if, however, the Board determines that it is an action, omission or failure which can be cured, the Company agrees to provide one cure period of sixty (60) days after receipt by the Executive of specific written notice of the issue. If the issue is not cured within the sixty (60) day period, or is of a nature that the Board determines cannot be cured, the Executive will be terminated for cause as specified in a Notice of Termination); (ii) the Executive engages in an act(s) of personal dishonesty, incompetence, or willful misconduct in connection with his employment, the performance of services or handling the affairs of the Company or BankUnited, FSB; (iii)

6

the conviction of Executive for, or a plea of guilty or nolo contendere to, a criminal act which is a felony, or which is a misdemeanor involving theft, dishonesty or moral turpitude; (iv) the Executive breaches a fiduciary duty owed to the Company involving personal profit, intentional failure to perform stated duties, or which could seriously prejudice the interest of the Company, BankUnited, FSB, its depositors, or shareholders; or (v) the Executive’s breach or willful violation of this Agreement, or of any law, rule, regulation, Code of Conduct, Insider Trading Policy, corporate policy (other than traffic violations or similar non-material offenses), or final cease and desist order in connection with his performance of services for the Company. An express termination by the Company for reasons other than those included above or which otherwise does not fall within another part of section 5, will be considered a termination without cause under paragraph 5.3. All disputes shall be resolved by Arbitration as provided in Section 24.

5.2 Termination for Death or Disability. This Agreement shall terminate automatically upon the Executive’s death and may be terminated by the Company upon the Executive’s Disability. Upon a termination by reason of the Executive’s Disability, the Company shall pay to the Executive or his beneficiaries, as the case may be, (i) any compensation or other obligations accrued for periods prior to the Date of Termination, all of which shall be paid within fifteen (l5) days after the Date of Termination, (ii) six (6) months of Base Salary, all of which shall be paid in installments consistent with the Company’s payroll practice for executives, and shall implement the provisions for the Executive’s Vested Benefits as of the Date of Termination. If Termination is due to the death of the Executive, the Company shall, within fifteen (15) days after the Date of Termination, pay to the Executive’s estate or beneficiaries, as the case may be, any unpaid Base Salary, Annual Bonus and benefits accrued for periods prior to the Date of Termination, or, if an alternative beneficiary is designated in proper legal form, the payments and benefits shall be paid to said designated beneficiary. In addition, the life insurance proceeds from the policies described in this Agreement shall be paid to his personal representative or such other persons as the Executive may have designated in writing.

5.3 Termination Without Cause. At any time the Company shall have the right to terminate the Executive’s employment hereunder by written notice to Executive; provided, however, that the Company shall (i) pay to Executive any unpaid Base Salary, and benefits and amounts due under the programs described in Section 4 up to the Date of Termination, (ii) pay to the Executive in a lump sum within thirty (30) days after the Date of Termination, an amount equal to the Executive’s Base Salary and benefits that would have become due to the Executive for the remainder of the then effective Term, but for the Company’s termination of the Executive pursuant to this Section 5.3 and (iii) implement the provisions of Section 4.7(c)(ii) for the Executive’s Vested Benefits as of the Date of Termination. The Company shall be deemed to have terminated the Executive’s employment pursuant to this Section 5.3 if such employment is terminated by the Company without Cause. The Company and the Executive hereby stipulate that the Company may condition the payment and delivery of the amounts specified in clause (ii) of the first sentence of this Section 5.3 on the receipt of the Executive’s resignation from any and all positions which he holds as an officer, director or committee member with respect to the Company, BankUnited, FSB or any subsidiary

7

or affiliate of either of them and gives the Company a full release of all then existing claims under this Agreement. Any disputes shall be resolved by Arbitration as provided in Section 24.

5.4 Resignation. In the event Executive resigns other than upon written request of the Company, Executive shall have not further right to any payments or grants due under this Agreement and all Executives’ rights and benefits under this Agreement shall terminate. A termination of this Agreement under Sections 5.1, 5.2, or 5.3 shall not be considered a “resignation” under Section 5.4 unless specifically agreed to in writing by the Executive and the Company.

5.5 Notwithstanding any provision of this Agreement to the contrary, no payment or benefit will be made to the Executive under Section 5.2 for termination due to Disability or under Section 5.3, prior to the expiration of six-months from the date of his termination of employment, if such payment or benefit will result in the imposition of an excise tax under Code section 409A.

7. Gross- Up of Change of Control Payments (if applicable).

(a) This Section shall apply if Executive’s employment is terminated upon or following a Change of Control as defined in Section 6 of this Agreement. If this Section applies, then, for any taxable year, the Executive shall be liable for the payment of an excise tax under section 4999 of the Code with respect to any payment in the nature of compensation made by the Company, the Bank or any direct or indirect subsidiary or affiliate of the Company or the Bank to (or for the benefit of) the Executive, the

9

Company shall pay to the Executive an amount equal to X determined under the following formula:

where

E = the rate at which the excise tax is assessed under section 4999 of the Code;

P = the amount with respect to which such excise tax is assessed, determined without regard to this Section 7;

FI = the highest marginal rate of income tax applicable to the Executive under the Code for the taxable year in question;

SLI = the sum of the highest marginal rates of income tax applicable to the Executive under all applicable state and local laws for the taxable year in question; and

M = the highest marginal rate of Medicare tax applicable to the Executive under the Code for the taxable year in question.

(b) Notwithstanding anything in this Section 7 to the contrary, in the event that the Executive’s liability for the excise tax under section 4999 of the Code for a taxable year is subsequently determined to be different than the amount determined by the formula (X + P) x E, where X, P and E have the meanings provided in Section 7(a), the Executive or the Company, as the case may be, shall pay to the other party at the time that the amount of such excise tax is finally determined, an appropriate amount, plus interest, such that the payment made under Section 7(a), when increased by the amount of the payment made to the Executive under this Section 7(b) by the Company, or when reduced by the amount of the payment made to the Company under this Section 7(b) by the Executive, equals the amount that should have properly been paid to the Executive under Section 7(a). The interest paid under this Section 7(b) shall be determined at the rate provided under section 1274(b)(2)(B) of the Code. To confirm that the proper amount, if any, was paid to the Executive under this Section 7, the Executive shall furnish to the Company a copy of each tax return which reflects a liability for an excise tax payment made by the Company, at least 20 days before the date on which such return is required to be filed with the Internal Revenue Service.

10

(c) Notwithstanding the provisions of Sections 7(a) and (b) above, in the event that the Executive shall be required to pay any additional amount of excise tax under section 4999 of the Code, or any successor to such section, or under any similar federal, State or local tax provision in connection with his receipt of payment in the nature of compensation from the Company, the Bank or any direct or indirect subsidiary or affiliate of the Company or the Bank to (or for the benefit of) the Executive, the Executive shall be entitled to receive an additional payment (a “Gross-Up Payment “) in an amount such that, after payment by the Executive of all taxes (and any interest or penalties imposed with respect to such taxes) and the excise tax under the Code and/or State and local tax provision imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the excise tax imposed by the Code or any State or local tax provision upon such compensation. For purposes of this paragraph 7(c), the term “taxes” shall include, but not be limited to, income taxes and the Executive’s share of any employment taxes.

(d) This section shall not apply to any entitlement to stock options, stock grants, or other securities of the Company.

8. Regulatory Considerations.

Notwithstanding anything herein to the contrary, any payments to Executive by BankUnited, whether pursuant to this Agreement or otherwise, are subject to and conditioned on compliance with Section 18(k) of the Federal Deposit Insurance Act, 12 U.S.C. § 1828(k) and any regulations promulgated thereunder.

9. Non-Competition.

9.1 The Executive acknowledges that during the Term of this Agreement, he will learn or be privy to valuable confidential business information, and he will develop and cultivate on behalf of BankUnited substantial relationships with past, present and prospective business customers of BankUnited. During the term of this Agreement with BankUnited, and thereafter, Executive will not, directly or indirectly, use or disclose to anyone, or authorize disclosure of any confidential information or trade secrets except for the benefit of BankUnited.

9.2 The Executive acknowledges that the confidentiality of the protected information with which Executive has been or may become privy is essential and proprietary to BankUnited and is owned and shall continue to be owned by BankUnited. The Executive agrees that at the termination of his employment, for whatever reason, he will return to BankUnited immediately any and all documents in whatever form that are in his possession or control and that contain, reflect or refer to confidential information or trade secrets.

9.3 During the Term of this Agreement and for a period of eighteen (18) months thereafter within all counties where BankUnited, FSB or its subsidiaries have branches or offices, the Executive shall not, either directly or indirectly, or for himself or through, on behalf of, or in conjunction with any other person, persons or legal entity,

11

own, maintain, operate, engage in, assist, be employed by, or have any interest in any business engaging or planning to be engaged in banking or offering other financial services offered by BankUnited, in any respect.

9.4 During the Term of this Agreement and for a period of eighteen (18) months thereafter, Executive shall not, except if this Agreement is terminated as a result of a Change of Control:

(a) either directly or indirectly, employ, retain the services of, or seek to employ or retain the services of any person who is at that time or was within the previous six (6) months employed by, or providing services to BankUnited or BankUnited, FSB, without the prior express written permission of BankUnited, which BankUnited may in its absolute discretion withhold;

(b) either directly or indirectly solicit or contact customers of BankUnited or BankUnited, FSB which solicitation is for or on behalf of any entity engaged in or seeking to be engaged in BankUnited’s banking or financial service business, or in direct competition with BankUnited.

(c) In the event of a violation of the provision of this Section, the Executive’s rights to receive grants of the Company’s Class A Common Stock shall terminate and no additional shares shall vest or be granted as provided in paragraph Section 4.7

9.5 Executive and BankUnited warrant that it is their intention to agree to restrictions on disclosure of confidential information and on competition that are as broad as permitted by Florida law (save only for the l8 month limitation set forth in paragraph 9.3) and hereby agree to subscribe to any expansion of the recited agreements as may be authorized by any subsequent amendment to, or interpretation of Florida Statute Section 542.335 (2000) or any other Florida law. For purposes of this non-competition provision, the Executive shall be deemed retained by BankUnited during any period of time in which he receives compensation from BankUnited or its successors.

9.6 The Executive acknowledges that Section 9 is reasonably necessary to protect the business interest of the Company and that the provisions of Section 2 and Section 9 are the essence of this Agreement for BankUnited and the Executive agrees that if he engages in activities prohibited by Section 9, irreparable harm to BankUnited will likely result, for which a remedy in the form of damages may not be ascertainable. Under such circumstances, the Executive acknowledges that BankUnited may seek temporary, preliminary or permanent injunctive relief against him in any court of competent jurisdiction upon three days written notice provided to the address listed in Section 16. This section shall not limit any other legal or equitable remedies BankUnited or its successors may have against the Executive for violation of this Agreement. The prevailing party in any action to enforce Section 9 of this Agreement shall be entitled to attorney’s fees and costs.

The Executive represents and warrants as of the Commencement Date, that he is not a party to any agreement, contract or understanding, whether of employment or otherwise, or subject to any governmental restriction, which would in any way restrict or prohibit him from undertaking or performing employment with the Company in accordance with the terms and conditions of this Agreement. The Executive further represents and warrants to the best of his knowledge, as of the Commencement Date, that he is physically and mentally capable of performing all the essential function of the job and all duties reasonably assigned to him for the entire term of this Agreement.

11. Withholding. The Company may withhold from any amounts payable under this Agreement such federal, state or local taxes as shall be required to be withheld pursuant to any applicable law or regulations. In the event Section 162(m) of the Internal Revenue Code of 1988 shall be applicable to Executive’s compensation, the Executive shall cooperate with the Company to restructure his compensation so as it to be fully deductible for income tax purposes; provided, however, such cooperation shall be on such terms, if any, as both the Executive and the Company agree, both utilizing good faith efforts to structure payments in such a manner that the Executive’s total compensation, on a present value basis, is not diminished.

12. Attorneys’ Fees. The Company agrees to pay such reasonable attorneys’ fees (not to exceed $15,000.00) as are incurred by the Executive with respect to advice and counsel concerning or related to the negotiation and preparation of this Agreement.

13. Enforcement Costs Upon a Change of Control. The Company is aware that upon the occurrence of a Change of Control, the Board of Directors or a stockholder of the Company may then cause or attempt to cause the Company to refuse to comply with its obligations under Section 6 of this Agreement, or may cause or attempt to cause the Company to institute, or may institute, litigation seeking to have Section 6 of this Agreement declared unenforceable, or may take, or attempt to take, other action to deny the Executive the benefits intended under Section 6 of this Agreement. In these circumstances, the purpose of this Agreement could be frustrated. It is the intent of the parties that the Executive not be required to incur the legal fees and expenses associated with the protection or enforcement of his rights under Section 6 of this Agreement by arbitration, litigation or other legal action because such costs would substantially detract from the benefits intended to be extended to the Executive hereunder, nor be bound to negotiate any settlement of his rights hereunder under threat of incurring such costs. Accordingly, if at any time after the Commencement Date, it should appear to the Executive that the Company is or has acted contrary to or is failing or has failed to comply with any of its obligations solely under Section 6 of this Agreement for the reason that it regards this Agreement to be void or unenforceable or for any other reason, or in the event that the Company or any other person takes any action to declare Section 6 of this Agreement void or unenforceable, or institutes arbitration, litigation or other legal action designed to deny, diminish or to recover from the Executive the benefits provided or intended to be provided to him under Section 6, and the Executive has acted in good faith to perform his obligations under this Agreement, the Company irrevocably authorizes the Executive from time to time to retain counsel of his choice at the expense

13

of the Company to represent him in connection with the protection and enforcement of his rights under Section 6. The reasonable fees and expenses of counsel selected from time to time by the Executive as herein above provided shall be paid or reimbursed to the Executive by the Company on a regular, periodic basis upon presentation by the Executive of a statement or statements prepared by such counsel in accordance with its customary practices. Counsel so retained by the Executive may be counsel representing other officers or key executives of the Company in connection with the protection and enforcement of their rights under similar agreements between them and the Company, and, unless in his sole judgment use of common counsel could be prejudicial to him or would not be likely to reduce the fees and expenses chargeable hereunder to the Company, the Executive agrees to use his best efforts to agree with such other officers or executives to retain common counsel.

14. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Florida, and applicable to contracts entered into and to be performed entirely within the State of Florida.

15. Non-Alienation. The Executive shall not have any right to pledge, hypothecate, anticipate, or in any way create a lien upon any amounts provided under this Agreement, and no payments or benefits due hereunder shall be assignable in anticipation of payment either by voluntary or involuntary acts or by operation of law. So long as the Executive lives, no person, other than the parties hereto, shall have any rights under or interest in this Agreement or in the subject matter hereof.

No modification or waiver of any provision of this Agreement shall be binding unless executed in writing by all parties hereto. No waiver of any provision of this Agreement shall be deemed or shall constitute a waiver of any other provision (whether or not similar), nor shall any such waiver constitute a continuing waiver. The failure of the Executive or the Company to insist upon strict compliance with any provision hereof shall not be deemed to be a waiver of such provision or any other provision thereof.

22. Non-Duplication. In the event that Executive shall perform services for BankUnited, FSB or any other direct or indirect subsidiary of the Company, any compensation or benefits provided to Executive by such other employer shall be applied to offset the obligations of the Company hereunder, it being intended that this Agreement set forth the aggregate compensation and benefits payable to Executive for all services to the Company and all of its direct or indirect subsidiaries, including BankUnited, FSB.

23. Survival. The provisions of Section 9 shall survive the expiration of the Term of the Agreement plus extensions, if any, or termination of the Agreement.

under applicable AAA rules of a notice of Claim is the equivalent of the filing of a lawsuit. Any dispute concerning this arbitration provision or whether a Claim is arbitrable shall be determined by the arbitrator(s). The arbitrator(s) shall have the power to award legal fees pursuant to the terms of this Agreement.

(f) By agreeing to binding arbitration, the parties irrevocably and voluntarily waive any right they may have to a trial by jury in respect of any Claim.
