Commencing on the Effective Date, and continuing through the date on which the Employee's employment terminates because of his death, retirement, disability, or any other cause, the Employee and the Corporation agree that the Employee shall defer into his Retirement Account the amount set forth in the Election of Deferral, Schedule A, Part 1,which the Employee would otherwise be entitled to receive from the Corporation in each Fiscal Year of the Corporation. The amount selected for deferral by the Employee pursuant to an Election of Deferral is referred to as the "Annual Deferral Sum". The amounts of compensation actually deferred, taking into account discontinuance of deferral pursuant to a Notice of Discontinuance, are hereinafter collectively included as the "Deferred Amounts". The Employee's Deferred Amounts shall be credited to the Employee's Retirement Account as of the dates such Deferred Amounts would, but for such deferral, be payable to the Employee. The Employee may elect an Annual Deferral Sum hereunder by filing an Election of Deferral. The initial Election of Deferral must be filed within one (1) day of the Effective Date of this Agreement. Such initial Election of Deferral, if any, shall be effective commencing with the following pay cycle. Thereafter, an Election of Deferral must be filed at least ten (10) days prior to the beginning of the Plan Year to which it pertains and shall be effective on the first day of the Plan Year following the filing thereof. The Employee may elect to defer a maximum Annual Deferral Sum of one hundred percent (100%) of base salary and one hundred percent (100%) of any incentive bonus. The minimum Annual Deferral Sum, if any is elected, shall be no less than one percent (1%) of Compensation. (b) Supplemental Deferral (Election of Employer) Commencing on the Effective Date, and continuing through the date on which the Employee's employment terminates because of death, normal retirement, disability, or any other cause, the Employer may at the discretion of the Board of Directors, make an Election of Contribution, as defined at paragraph 4., below. While the amount of the Election of Contribution shall be determined at the sole discretion and in such manner as the Board of Directors determines from time to time, the initial -134- policies and procedures for determination of the amount of such Election of Contribution is set forth at Exhibit A, which may be amended at any time, Provided However, that the Initial Election of Contribution, set forth at Exhibit D shall continue in effect unless terminated or amended by the Board of Directors by subsequent termination or election. The amount credited pursuant to an Election of Contribution is referred to as the "Annual Supplemental Sum". The sum of all Annual Supplemental Sums set forth on all Elections of Contribution for the Employee are hereinafter collectively referred to as the "Supplemental Compensation". The Employee's Supplemental Compensation shall be credited to the Employee's Retirement Account as of the dates such Annual Supplemental Sum is approved, or otherwise stated to be credited by resolution of the Board of Directors of the Employer. (c) Vesting The Employee shall vest and have a nonforfeitable right to all amounts credited to his or her Retirement Account as Supplemental Deferrals, and all Additions related thereto, in accordance with the schedule set forth at Exhibit C, attached hereto. In the event Exhibit C is not completed or there is a change in control of the Employer, the employee shall be immediately vested in all such amounts credited to his or her Retirement Account. For purposes of applying any vesting schedule, the Employee shall be considered as having a completed Year of Service for each complete year of full-time service with the Employer or an Affiliate, measured from the later of (1) the Employee's first date of employment or, (2) the date any amount is first credited to the Retirement Account of the Participant under this Agreement. To the extent that any Supplemental Deferrals credited to the Employee's Retirement Account are not vested at the time such amounts are otherwise payable to the Employee under paragraph 6. 7., 9., or 10., below, such amounts shall be forfeited. 3. ADDITIONS TO DEFERRED AMOUNTS AND AMOUNT OF SUPPLEMENTAL. The Corporation agrees that it will credit Deferred Amounts in the Employee's Retirement Account with additions thereon ("Additions") from and after dates Deferred Amounts are credited to the Retirement Account. Additions to Deferred Amounts shall accrue commencing on the date the Retirement Account first has a positive balance and shall continue up to the date that the Retirement Account has been reduced to zero. Additions shall be calculated as an amount (the "As If Rate") equal to the yield that would be realized, including any dividends, interest, or other current yield, as well as any capital gain or loss based on an adjustment to fair market value on any date of calculation, as if hypothetically invested in whole or fractional shares in the assets set forth at Schedule 2 (the Calculation Assets), which may be changed at the sole discretion of the Employer, from time to time. The Employer shall have no obligation to actually acquire any of the Calculation Assets set forth at Schedule 2, and such return shall be only for purposes of calculating Additions to Deferred Amounts hereunder. The Employee shall have no rights in or to any Calculation Assets set forth at Schedule 2, as provided elsewhere in this Agreement. The As If Rate shall be adjusted on the last day of each fiscal quarter the plan year at the mean trading price of the Calculation Assets on such date or the first business date thereafter, as quoted in Barrons financial news publication, or in the absence of a quotation therein, in a similar publication or other authoritative valuation of the specified Calculation Assets. Any such designation of new Calculation Assets by the Employer must be in writing. For purposes of calculating Additions, it shall be assumed that the Calculation Assets is sold and the alternate Calculation Assets is purchased on the first business day following such revised designation by the Corporation. -135- Additions related to Supplemental Deferrals are subject to any Vesting Schedule attached hereto and determined by the Employer. Additions to Employee Deferrals are not subject to any Vesting Schedule. 4. ELECTION TO MAKE CONTRIBUTION. The Corporation may make an Election of Contribution by action of the Board of Directors and set forth in a form of Election of Contribution as set forth at Exhibit A, Part 2, or such similar form of election as may be approved by the Board of Directors. Any Election of Contribution shall apply only to the amounts and years set forth in such Election of Contribution and shall not require any subsequent contributions beyond those set forth in such Election of Contribution, Provided However, that the Initial Election of Contribution at Exhibit D shall remain in effect unless subsequently terminated or amended by the Board of Directors. 5. TERMINATION OF PLAN. The Employer may at any time during the term of this Agreement, modify, suspend or terminate this Agreement in any manner or at any time. Such modification, suspension or termination may not reduce the Employee's Retirement Account, but may alter modify, suspend or terminate future Annual Supplemental Sums and any other aspects of the Agreement. 6. (a) RETIREMENT BENEFIT. The Corporation agrees that, from and after the retirement of the Employee from the service of the Corporation upon reaching his or her Early Retirement Date or Normal Retirement Date, the Corporation shall thereafter pay as a retirement benefit ("Retirement Benefit") to the Employee in the amount of the Employee's entire Accrued Benefit in equal monthly installments for one hundred eighty (180) consecutive months, commencing on the first day of the calendar month immediately following the Employee's retirement; provided however, that the Employee may, at his or her sole option make one election prior to the time benefit payments begin to receive the Accrued Benefit in his or her Retirement Account in a lump sum or equal monthly installment payments over a shorter period of either one hundred twenty (120) or sixty (60) months, to be designated by him in writing (by delivery to the Corporation of a completed Exhibit D, or similar statement) than would otherwise apply, or in a single payment. The election referred to in the preceding sentence must be made at least one year prior to the date benefit payments begin and shall be irrevocable. In the event of such election by the Employee, the first designated monthly payment or the single payment, whichever applies, shall be due and payable on the first day of the calendar month immediately following the Employee's retirement. Monthly installment payments, if applicable, shall continue monthly thereafter, for the period designated by the Employee. (b) ELECTION OF BENEFITS UPON RETIREMENT DATE. The Employee shall have the option, upon attaining his or her Early Retirement Date or Normal Retirement Date, to elect to receive his or her Retirement Benefit, notwithstanding his or her continued employment with the Corporation after attaining the Early Retirement Date or Normal Retirement Date. The Employee's election to receive his or her Retirement Benefit notwithstanding continued employment must be made in writing at least one year prior to Early Retirement Date or Normal Retirement Date, whichever applies. The Retirement Benefit payable upon election pursuant to this paragraph 6. b. shall be the amount that would have been payable had the Employee retired from service with the Corporation as of the Early Retirement Date or Normal Retirement Date, whichever applies. Any such election shall be irrevocable, and shall result in the termination of the Employee's right to any further deferrals hereunder. 7. DISABILITY RETIREMENT. Notwithstanding any other provision hereof, the Employee shall be entitled to receive payments hereunder prior to his or her Early Retirement Date or Normal Retirement Date, whichever applies, in any case in which it is -136- determined by a duly licensed physician selected by the Corporation that, because of ill health, accident, disability or general inability because of age, the Employee is no longer able, properly and satisfactorily, to perform his or her regular duties as an Employee. If the Employee's employment is terminated pursuant to this paragraph 7., the disability retirement benefit payable hereunder ("Disability Retirement Benefit") shall be that amount that would have been payable as a Retirement Benefit had the Employee attained his or her Normal Retirement Date on the date of the physician's disability determination. The Disability Retirement Benefit payable under this paragraph 7. shall be distributed in accordance with the provisions of paragraph 6.a. as if the Employee had retired on the date of the physician's disability determination. 8. (a) DEATH BENEFIT PRIOR TO COMMENCEMENT OF RETIREMENT BENEFITS. In the event of the Employee's death while in the employment of the Corporation and prior to commencement of the Retirement Benefits or Disability Retirement Benefits, the Corporation shall pay as a survivor's benefit the Employee's entire Survivor Benefit in a single lump sum to the Employee's designated beneficiary (the "Beneficiary"), in accordance with the last such designation received by the Corporation from the Employee prior to death. provided however, that the Beneficiary may elect to receive the Survivor Benefit in either ten (10) or five (5) annual installments, to be designated in writing by such Beneficiary. If no such designation has been received by the Corporation from the Employee prior to death said payments shall be made to the Employee's then living spouse, if any, and if there is no such living spouse, then said payment shall be made to the living children of the Employee, if any, in equal shares, and if there is no surviving spouse or surviving children, then such payments shall be made to the estate of the Employee. Such payments shall be made on the first day of the second month following the Employee's death. (b) DEATH BENEFIT AFTER COMMENCEMENT OF BENEFITS. In the event of the Employee's death after commencement of Retirement benefits, Normal Retirement Benefits, or Disability Retirement Benefits, but prior to the completion of all such payments due and owing hereunder, the Corporation shall pay the balance of the Accrued Benefit in a single lump sum the Employee's designated beneficiary, in accordance with the last such designation received by the Corporation from the Employee prior to his or her death. If no such designation has been received by the Corporation from the Employee prior to death said payments shall be made to the Employee's then living spouse, if any, and if there is no such living spouse, then said payment shall be made to the living children of the Employee, if any, in equal shares, and if there is no surviving spouse or surviving children, then such payments shall be made to the estate of the Employee. Such payments shall commence on the first day of the second month following the Employee's death. At its sole option, the Corporation may pay the Employee's entire Accrued Benefit as a single lump sum. 9. TERMINATION BENEFIT. In the event of either (a) the Employee's termination of employment with the Corporation before the Early Retirement Date for any reason, other than disability, retirement or death, or (b) a Change of Control of the Employer, the Corporation shall pay to the Employee, as compensation for services rendered prior to such termination, an amount equal to the total Retirement Account (the Termination Benefit) in the manner pre- determined at the time of deferral and set forth in Exhibit A -137- (Part 1) Election of Deferral. In the absence of such designation a single lump sum shall be payable. The Termination Benefit shall be payable on the first day of the second month following the termination of the Employee's employment with the Corporation. 10. HARDSHIP WITHDRAWAL. In the event the Employee suffers an unforeseen financial emergency, as defined hereafter, the Corporation may, if it deems advisable in its sole and absolute discretion, distribute to or utilize on behalf of the Employee as a hardship benefit (the "Hardship Benefit") any portion of the Employee's Retirement Account. The Corporation shall have exclusive authority to determine whether to make a hardship distribution, and the Corporation's decision shall be final and binding on all parties. Any hardship distribution shall, like all distributions, reduce the amounts available for subsequent distributions and be deducted from the Retirement Account. The Employee shall apply for such a Hardship Benefit in writing in a form approved by the Corporation and shall provide such additional information as the Corporation shall require. For purposes of this Paragraph, "unforeseen financial emergency" means an immediate and heavy financial need caused by an unforeseeable emergency, as described in Treasury Regulations Section 1.457-2(h) (4) and (5), resulting from any of the following, and in an amount not in excess of the amount needed to pay for the following unreimbursed expenses: (a) expenses which are not covered by insurance and which the Employee or his or her spouse or dependents (as defined in Code Section 152 (a)) has incurred as a result of, or is required to incur in order to receive, medical care described in Code Section 213 (d), as a result of a sudden or unexpected illness; (b) payment of funeral, marital dissolution and other costs recognized by the Company to pose an immediate and heavy financial need on the Employee, or (c) payment of extraordinary, unforeseeable expenses attributable to forces beyond the Employee's control in order to prevent eviction of the Employee from his or her principal residence or foreclosure on the mortgage of the Employee's principal residence. No distribution shall be made pursuant to this paragraph in excess of the amount of the immediate and heavy financial need of the Participant. The amount of the immediate and heavy financial need may include any amounts necessary to pay federal, state, or local income taxes or penalties reasonably anticipated to result from the distribution. Any distribution under this paragraph shall reduce the Retirement Account. Any distribution under this paragraph shall be limited to the lesser of either: (a) the amount designated by the Employee as a requested Hardship benefit in a form determined by the Company, or (b) Fifty Percent (50%) of the Retirement Account. 11. IN SERVICE DISTRIBUTION. The lesser of either: (a) the In Service Distribution amount designated by the Employee on a validly submitted Election of Deferral in the form set forth at Exhibit A, or (b) the Accrued Benefit, shall be distributed in a lump sum on the In Service Distribution Date. The In Service Distribution Date shall be the later of either: (a) the In Service Distribution Date set forth at Exhibit A, or (b) a date 12 months after the Election Date as defined in this Agreement. No In Service Distribution shall be effective unless it is elected on an Election of Deferral submitted and dated as provided at Exhibit A. 12. OFFSET FOR OBLIGATIONS TO CORPORATION.

BENEFICIARY DESIGNATION. The Employee shall have the right, at any time to submit in substantially the form attached hereto as Exhibit B, a written designation of primary and secondary beneficiaries to whom payment under this Agreement shall be made in the event of death prior to complete distribution of the benefits due and payable under the Agreement.

If the claim is wholly or partially denied, the Corporation shall provide a written notice within ninety (90) days specifying the reason for the denial, the plan provisions on which the denial is based, and additional material or information necessary to receive benefits, if any. Also, such written notice shall indicate the steps to be taken if a review of the denial is desired. If a claim is denied and a review is desired, the Employee (or designated beneficiary in the case of the Employee's death) shall notify the Corporation in writing within sixty (60) days after receipt of a written notice of a denial of a claim. In requesting a review plan documents and submit any written issues and comments her or she feels are appropriate. The Corporation shall then review the claim and provide a written decision within sixty (60) days of receipt of a request for review. This decision shall state the specific reasons for the decision and shall include references to specific provisions on which the decision is based. 15. ASSIGNMENT OF RIGHTS. Neither the Employee nor any designated beneficiary shall have any right to sell, assign, transfer, or otherwise convey the right to receive any payments hereunder without the prior written consent of the Corporation. 16.

It is expressly understood by the parties hereto that this Agreement relates exclusively to discretionary supplemental compensation as set forth in this Agreement. This Agreement is not intended to be an employment contract, or to obligate the Company to make any contribution of an Annual Supplemental Sum, other than as approved at the discretion of the Board of Directors. 17. CONSTRUCTION OF AGREEMENT. Any payments under this Agreement shall be independent of, and in addition to, those under any other plan, program, or agreement which may be in effect between the parties hereto, or any other compensation payable to the Employee or the Employee's designated beneficiary by the Corporation. 18. NO TRUST CREATED. Nothing contained in this Agreement, and no action taken pursuant to its provisions by either party hereto, shall create, nor be construed to create, a trust of any kind of a fiduciary relationship between the Corporation and the Employee, the Employee's designated beneficiary, any other beneficiary of the Employee or any other person. 19. BENEFITS PAYABLE ONLY FROM GENERAL CORPORATE ASSETS; UNSECURED GENERAL CREDITORS STATUS OF EMPLOYEE. The payments to the Employee, the Employee's designated beneficiary or any other beneficiary hereunder -139- shall be made from assets which shall continue, for all purposes, to be a part of the general, unrestricted assets of the Corporation; no person shall have nor acquire any interest in any such assets by virtue of the provisions of this Agreement. The Corporation's obligation hereunder shall be an unfunded and unsecured promise to pay money in the future. To the extent that the Employee or any person acquires a right to receive payments from the Corporation under the provisions hereof, such right shall be no greater than the right of any unsecured general creditor of the Corporation; no such person shall have nor require any legal or equitable right, interest or claim in or to any property or assets of the Corporation. In the event that, in its sole discretion, the Corporation purchases an insurance policy or policies insuring the life of the Employee (or any other property) to allow the Corporation to recover the cost of providing the benefits, in whole, or in part, hereunder, neither the Employee, the Employee's designated beneficiary, any other beneficiary nor any other person shall have nor acquire any rights whatsoever therein or in the proceeds therefrom. The Corporation shall be the sole owner and beneficiary of any such policy or policies and, as such, shall possess and, may exercise all incidents of ownership therein. No such policy, policies or other property shall be held in any trust for the Employee or any other person nor as collateral security for any obligation of the Corporation hereunder. 20. AMENDMENT.

Matching Contribution Deficiency The Company has adopted a deferred savings plan which allows each Employee to contribute fifteen percent (15%) of compensation on a pre-tax basis. Under the terms of the deferred savings plan, the Matching Contributions will be equal to one hundred percent (100%) of such individual's deferred savings contributions, to the extent those deferred savings contributions do not exceed two percent (25%) of his/her Eligible Earnings, and (ii) the Matching Contributions will be equal to twenty five percent (25%) of such individual's deferred savings contributions, to the extent those deferred savings contributions exceed two percent (2%) but not more than six percent (6%) of his/her Eligible Earnings. However, the aggregate Matching Contribution made on behalf of any Qualified Participant shall not exceed Two Thousand dollars ($2,000.00) per Plan Year. Highly Compensated Employees, as defined by the Internal Revenue Code, may be restricted as to the amount they may contribute to the deferred savings plan as a result of their status as Highly Compensated Employees, and therefore the related Matching Contribution that would otherwise have been contributed for their benefit may be restricted. The amount of the Matching Contribution that the Company is actually precluded from contributing and would otherwise have contributed to the deferred savings plan on behalf of the Employee, but for the application of the limitations on contributions by Highly Compensated Employees is referred to here as the Matching Contribution Deficiency. This contribution is subject to the terms of the Plan, and may be terminated or amended at the sole discretion of the Board of Directors, provided however, that this Initial Election of Contribution shall remain in effect from year to year unless terminated or amended by subsequent act of the Board of Directors. -152-
