UNION STATE BANK

KEY EMPLOYEES’ SUPPLEMENTAL INVESTMENT PLAN

The Supplemental Employees’ Investment Plan for Salaried Employees of Union State Bank (the “Plan”) was adopted effective December 1, 1994. The Plan was established and maintained by Union State Bank solely for the purpose of providing to a select group of highly compensated or management personnel who participate in the U.S.B. Holding Co., Inc. Employee Stock Ownership Plan (with 401(k) Provisions) (“Qualified Plan”) benefits attributable to (i) contribution allocations which would otherwise be made under the Qualified Plan but for the compensation limitation of Internal Revenue Code of 1986 (“Code”) Section 401(a)(17), and (ii) contributions equal to amounts in excess of the limitations on annual additions imposed by Code Section 415.

Union State Bank desires to expand the purposes of the Plan to permit certain key executive employees designated by its Board of Directors to defer portions of their compensation, in order to continue to attract and retain talented executives with a competitive compensation package. Accordingly, Union State Bank has adopted the Plan for its key executive employees, and has restated and amended the Plan to provide for such deferral of compensation effective as of July 1, 1997. The Plan is a non-qualified deferred compensation plan subject to the requirements of section 409A of the Code and has been further amended and restated effective January 1, 2005 to reflect these requirements.

It is the intention of the parties that the arrangements contemplated by the Plan be unfunded for tax purposes and for purposes of Title I of ERISA.

Accordingly, Union State Bank hereby adopts, amends and restates the Plan pursuant to the terms and provisions set forth below:

GENERAL PROVISIONS

Section 8.1.         Participant’s Rights Unsecured. The Plan at all times shall be entirely unfunded and no provision shall at any time be made with respect to segregating any assets of the Company for payment of any distributions hereunder; provided, however, that the Company in its sole discretion may establish a reserve, segregate specific assets, or create a trust or other vehicle, to hold assets for purposes of administering the Plan or for its own financial purposes. The right of a Participant or his designated beneficiary to receive a distribution hereunder shall be an unsecured claim against the general assets of the Company, and neither the Participant nor a designated beneficiary shall have any rights in or against any specific assets of the Company, including any reserve, segregated assets, or trust assets that may be maintained by the Company.

Section 8.2.         No Guarantee of Benefits. Nothing contained in the Plan shall constitute a guaranty by the Company or any other person or entity that the assets of the Company will be sufficient to pay any benefit hereunder.

Section 8.3.         No Enlargement of Employee Rights.

Establishment of the Plan shall not be construed to give any Participant the right to be retained in the service of the Company.

No interest of any person or entity in, or right to receive a distribution under, the Plan shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, anticipation, or other alienation or encumbrance of any kind; nor may such interest or right to receive a distribution be taken, either voluntarily or involuntarily for the satisfaction of the debts of, or other obligations or claims against, such person or entity, including claims for alimony, support, separate maintenance, and claims in bankruptcy proceedings.

Section 8.5.         Applicable Law. The Plan shall be construed and administered under the laws of the State of New York.

Section 8.6.         Incapacity of Recipient. If any person entitled to a distribution under the Plan is deemed by the Company to be incapable of personally receiving and giving a valid receipt for such payment, then, unless and until claim therefore shall have been made by a duly appointed guardian or other legal representative of such person, the Company may provide for such payment or any part thereof to be made to any other person or institution then contributing toward or providing for the care and maintenance of such person. Any such payment shall be a payment for the account of such person and a complete discharge of any liability of the Company and the Plan therefor.

Section 8.7.         Corporate Successors. The Plan shall not be automatically terminated by a transfer or sale of assets of the Company or by the merger or consolidation of the Company into or with any other corporation or other entity, but the Plan shall be continued after such sale, merger, or consolidation only if and to the extent that the transferee, purchaser, or successor

entity agrees to continue the Plan. In the event that the Plan is not continued by the transferee, purchaser, or successor entity, then the Plan shall terminate subject to the provisions of Section 7.2.

Section 8.8.         Unclaimed Benefit. Each Participant shall keep the Company informed of his current address and the current address of his designated beneficiary. The Company shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Company within three (3) years after the date on which payment of the Participant’s Deferred Compensation Accounts may first be made, payment may be made as though the Participant had died at the end of the three-year period. If, within one additional year after such three-year period has elapsed, or, within three year after the actual death of a Participant, the Company is unable to locate any designated beneficiary of the Participant, then the Company shall have no further obligation to pay any benefit hereunder to such Participant or designated beneficiary and such benefit shall be irrevocably forfeited.

Section 8.9.         Limitations on liability. Notwithstanding any of the preceding provisions of the Plan, neither the Company nor any individual acting as employee or agent of the Company shall be liable to any Participant, former Participant or other person for any claim, loss, liability, or expense incurred in connection with the Plan. However, the preceding sentence shall not apply to liability for criminal acts or willful misconduct.

Section 8.10.       Compliance with Section 409A of the Code. The Plan is intended to be a non-qualified deferred compensation plan described in section 409A of the Code. The Plan shall be operated, administered and construed to give effect to such intent. In addition, the Plan shall be subject to amendment, with or without advance notice to Participants and other interested parties, and on a prospective or retroactive basis, including but not limited to amendment in a manner that adversely affects the rights of participants and other interested parties, to the extent necessary to effect such compliance.

(a)         Each Participant’s benefit under the Plan shall become 100% vested upon the occurrence of a Change in Control of the Employer while the Participant is an Employee.

(b)          A Change in Control of the Employer shall be deemed to have occurred upon the happening of any of the following events:

(i)           consummation of a reorganization, merger, or consolidation of U.S.B. Holding Co., Inc. with one or more other persons, other than a transaction following which more than 20% of the securities entitled to vote generally in the election of directors of the entity resulting from such transaction are beneficially owned (within the meaning of Rule 13d-3 promulgated under the Exchange Act) by a person who, on January 1, 1994, beneficially owned (within the meaning of Rule 13d-3 promulgated under the Exchange Act) more than 20% of the securities entitled to vote generally in the election of directors of U.S.B. Holding Co., Inc.

(ii)          a transaction or series of transactions resulting in the acquisition of all or substantially all of the assets of U.S.B. Holding Co., Inc. or beneficial ownership

Holding Co., Inc. entitled to vote generally in the election of directors by any person or by any persons acting in concert, who do not, prior to such transaction or series of transactions already beneficially own more than 20% of such outstanding securities;

(iii)         a complete liquidation or dissolution of U.S.B. Holding Co., Inc., or approval by its stockholders of a plan for such liquidation or dissolution.

In no event, however, shall a Change in Control be deemed to have occurred as a result of any acquisition of securities or assets of U.S.B. Holding Co., Inc., an affiliated employer, or a subsidiary of either of them, by U.S.B. Holding Co., Inc., an affiliated employer, or a subsidiary of either of them, or by any employee benefit plan maintained by any of them. For purposes of this section 9.5(b), the term “person” shall have the meaning assigned to it under sections 13(d)(3) or 14(d)(2) of the Exchange Act.

IN WITNESS WHEREOF, the Company has formally adopted this amended and restated Plan effective as of January 1, 2005.
