Employment Contracts and Change-in-Control Arrangements

Patrick K. Gill

On August 10, 2009, Patrick K. Gill, O.A.K.'s President and Chief Executive Officer, entered into a management continuity agreement with O.A.K. Pursuant to the management continuity agreement, if the merger with Chemical Financial Corporation ("Chemical") occurs and Mr. Gill's employment is terminated within 6 months before or 36 months after the merger, unless the termination is because of death, disability, by Chemical for cause or by Mr. Gill other than for good reason, Mr. Gill will receive severance benefits. Mr. Gill may also terminate his employment with or without good reason anytime during the period that is 180-210 days after the effective date of the merger and receive the severance benefits. Please see "Recent Development – Proposed Merger with Chemical Financial Corporation," contained in our annual report on Form 10-K, filed on February 12, 2010, for a more detailed description of the merger.

Under the management continuity agreement, Mr. Gill's severance benefits would be: (i) a cash amount equal to 2.99 multiplied by the sum of (a) Mr. Gill's annual base salary, plus (b) Mr. Gill's highest actual annual bonus paid during the five full calendar years preceding the merger, which shall be paid in equal bi-weekly installments over 36 months, (ii) continuation of certain health, life and disability insurance for 36 months, and (iii) outplacement services up to a maximum of $10,000.

If any part of the severance benefits constitute a "parachute payment" under Section 280G of the Code, then, if the aggregate present value of such payments exceeds 2.99 times Mr. Gill's base amount as defined in Section 280G of the Code, then the parachute payments will be reduced to an amount equal to 2.99 times Mr. Gill's base amount.

On January 7, 2010, Mr. Gill entered into a transition agreement with Chemical. Under the terms of the transition agreement, after the closing Mr. Gill will be employed by Chemical as Chairman of Chemical's West Region. Chemical may terminate Mr. Gill's employment at any time with or without cause. If Mr. Gill's employment is terminated in a manner that would entitle him to benefits under his management and continuity agreement, severance benefits will be paid as set forth in the management and continuity agreement.

Under his transition agreement, Mr. Gill is entitled to the following payments: (i) annual salary of $285,000, (ii) $40,000 if he does not terminate his employment during the 90 days immediately following the merger, (iii) $45,000 if he does not terminate his employment during the period that is 91-180 days after the merger, and (iv) $40,000 at the closing of the merger as consideration for Mr. Gill extending his non-competition and non-solicitation covenants in his management continuity agreement from 12 months post-termination of employment to 18 months post-termination of employment. Mr. Gill will also receive the first and second payments described in this paragraph if Chemical terminates his employment without cause (as defined in Mr. Gill's management continuity agreement).

In the event that any of the benefits under Mr. Gill's transition agreement trigger excise tax imposed by Section 409A of the Internal Revenue Code, then Chemical will pay Mr. Gill a gross-up payment equal to any excise tax imposed on the payments.

Joel F. Rahn

On January 7, 2010, Joel F. Rahn, O.A.K.'s Chief Loan Officer, entered into a retention bonus and non-competition agreement with Chemical. Under the terms of the retention bonus and non-competition agreement, Mr. Rahn will be employed by Chemical as Senior Vice President of Credit Administration. Under the retention bonus and non-competition agreement, Mr. Rahn will: (i) be paid an annual salary of $160,000, (ii) be granted $100,000 of restricted stock units on the closing date of the merger, which will vest 50% on each of the first and second anniversaries of the closing of the merger, if Mr. Rahn is employed with Chemical on those dates, (iii) receive a one time payment of $200,000 as consideration for a covenant not-to-compete that will last at least 18 months after the closing of the merger and may last between 12 to 18 months after termination of employment depending on when and how Mr. Rahn's employment with Chemical terminates, and (iv) be eligible to receive two retention bonus payments totaling $200,000, which will be paid 50% on the first anniversary of the closing and 50% on the second anniversary of the closing, if Mr. Rahn is employed with Chemical on those dates.

In the event that any of the benefits under Mr. Rahn's retention and non-competition agreement trigger excise tax imposed by Section 409A of the Internal Revenue Code, then Chemical will pay Mr. Rahn a gross-up payment equal to any excise tax imposed on the payments.

James A. Luyk

On August 10, 2009, James A. Luyk, O.A.K.'s Chief Financial Officer and Chief Operating Officer, entered into a management continuity agreement with O.A.K. Pursuant to the management continuity agreement, if the merger with Chemical occurs and Mr. Luyk's employment is terminated within 6 months before or 36 months after the merger, unless the termination is because of death, disability, by Chemical for cause or by Mr. Luyk other than for good reason, Mr. Luyk will receive severance benefits. Mr. Luyk may also terminate his employment with or without good reason anytime during the period that is 180-210 days after the effective date of the merger and receive the severance benefits.

Under the management continuity agreement, Mr. Luyk's severance benefits would be: (i) a cash amount equal to 2.75 multiplied by the sum of (a) Mr. Luyk's annual base salary, plus (b) Mr. Luyk's highest actual annual bonus paid during the five full calendar years preceding the merger, which shall be paid in equal bi-weekly installments over 30 months, (ii) continuation of certain health, life and disability insurance for 30 months, and (iii) outplacement services up to a maximum of $10,000.

If any part of the severance benefits constitute a "parachute payment" under Section 280G of the Code, then, if the aggregate present value of such payments exceeds 2.99 times Mr. Luyk's base amount as defined in Section 280G of the Code, then the parachute payments will be reduced to an amount equal to 2.99 times Mr. Luyk's base amount.

DIRECTOR COMPENSATION

The following table sets forth summary information concerning the total compensation paid or accrued for all services rendered by non-employee members of our Board of Directors for the year ended December 31, 2009.

Director Compensation

Name	Fees Earned or Paid in Cash	Total Compensation
Robert F. Dentzman	$25,700	$25,700
Norman J. Fifelski	$20,900	$20,900
James B. Meyer	$19,400	$19,400
Grace O. Shearer	$25,700	$25,700
David G. Van Solkema	$26,300	$26,300
Stephanie L. Leonardos	$18,600	$18,600

Director Fees Earned or Paid in Cash

The directors of the Corporation do not receive any compensation for their services as directors of the Corporation. Non-employee directors of Byron Bank (the "Bank"), the Corporation's wholly owned subsidiary, are paid an annual retainer fee of $8,000 for their service. Directors receiving the annual retainer can elect to be paid in cash or have the annual retainer contributed to the 1998 director deferred compensation plan described below. Non-employee directors also receive $500 per Board meeting attended and $300 per committee meeting attended. In addition, the chairperson of the Board receives an annual fee of $3,000 and the chairperson of the Audit Committee receives an annual fee of $1,500.

Director Deferred Compensation Plans

In 1988, the Bank adopted a director's deferred compensation plan that provides for benefit payments to the participant and his or her family upon retirement or death. Directors Fifelski and Van Solkema are the only current directors who are participants in this plan. This plan allowed for the deferral of director fees in return for the payment of future benefits. The participant account balances are credited with an appreciation factor equal to a floating rate determined by an independent third-party. The total accrued liability of the Bank under this plan was $609,851 at December 31, 2009. The Bank purchased life insurance policies on the lives of the participating directors with the Bank as the owner and beneficiary. The cash surrender value of the policies was $1,719,167 at December 31, 2009. As of January 1, 1997, no further deferrals of directors' fees were allowed under this plan.

Beginning in 1998, the Bank entered into deferred compensation agreements with individual directors interested in deferring their annual retainers. Effective January 1, 2008, the individual agreements for all current directors (and one former director) were replaced by the Byron Bank Deferred Compensation Plan for Directors. Under this plan, directors can elect to defer the annual retainer they would otherwise receive in cash for their services as a director. Deferred director fees are credited to a bookkeeping account maintained by the Bank for each director. The Board is authorized to direct the Bank to purchase policies of life insurance on the lives of participating directors as a means of funding the Bank's obligations under the plan. If a life insurance policy is purchased with respect to a participating director's life, the Bank is the owner and beneficiary of the policy. Each participating director's account balance is increased each year by an interest factor based on the guaranteed dividend rate payable with respect to the related life insurance policy, or if no such policy is maintained for the director, based on the Bank's announced interest rate for 60-month CDs. The fees deferred by each director under the plan become payable as follows:

¡	Generally, upon the later of the director reaching the age of 65 or his or her retirement or resignation from the Board (the later of these dates is referred to as the "trigger date"), the cash value of the life insurance policy maintained on the director's life is payable to the director in 15 equal annual installments. In addition, each installment is increased by the projected increase in such cash value during the 12 months following the trigger date. If no life insurance policy is maintained for the director, the amount paid out to the director under the plan is the account balance as of the trigger date, which is payable in 15 equal annual installments.

¡	If a director dies before a trigger date described above, the plan requires the Bank to pay the director's designated beneficiary(ies) the death benefit received by the Bank under the life insurance policy maintained on the director's life or, if no such insurance policy is maintained, the director's account balance as of the date of death. The amount payable to the beneficiary(ies) is payable in 10 equal annual installments.

¡	If a director dies while receiving annual payments from the Bank under the Plan, such payments are to be continued to the director's designated beneficiary(ies).

¡	If there is a change in control of the Bank, all directors who still have account balances under the plan will receive a lump sum payment generally equal to the present value of the payments they would otherwise be entitled to receive if the plan continued and they retired from the Board as of the date of the change in control.

At December 31, 2009, the aggregate plan liability was $586,718 and the aggregate cash surrender value of insurance policies purchased on the lives of participating directors was $756,171.

Prior Director Stock Option Plan

In 1999, the Board of Directors adopted the OAK Financial Corporation 1999 Directors' Stock Option Plan, which was approved by the Corporation's shareholders. The purpose of the plan was to provide a non-cash method of compensating and recruiting directors for the Corporation. Stock options to purchase 666 shares were granted to each non-employee director during each of the four years prior to 2003. No options have been granted under the plan since 2002. The plan expired in January of 2009, and the Board has decided not to propose a renewal or replacement of the plan at this time. To date, an aggregate of 2,662 options are outstanding, and no options have been exercised.

RELATED PARTY TRANSACTIONS

Certain directors and officers of the Corporation have had and are expected to have in the future, transactions with the subsidiaries of the Corporation, or have been directors or officers of corporations, or members of partnerships, which have had and are expected to have in the future, transactions with the subsidiaries of the Corporation. All such transactions with officers and directors, either directly or indirectly, have been made in the ordinary course of business and on substantially the same terms, including interest rates and collateral, as those prevailing at the same time for comparable transactions with other customers, and these transactions do not involve more than the normal risk of collection or present other unfavorable features. All such future transactions, including transactions with principal shareholders and other Corporation affiliates, will be made in the ordinary course of business, on terms no less favorable to the Corporation than with other customers, and will be subject to approval by a majority of the Corporation's independent, outside, disinterested directors.

Each of the Corporation's directors, other than Patrick Gill, are independent under Nasdaq listing standards.

ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

RELATIONSHIP WITH INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Plante & Moran, PLLC, independent certified public accountants, have audited the financial statements of the Corporation for the year ended December 31, 2009. The following table sets forth the aggregate fees billed to us for the fiscal years ended December 31, 2009 and December 31, 2008, by our principal auditing firm, Plante & Moran, PLLC:

	Fees of Independent Accountants

	2009	2008
Audit Fees	$123,500	$118,000
Audit-related Fees	9,000	10,550
Tax Fees	11,245	9,500
All Other Fees	19,100	0

The amounts shown for "Audit-related Fees" were for services related to the audit of benefits plans in both 2009 and 2008. The amounts shown for "Tax Fees" were for corporate tax compliance, tax advice and tax planning services. The amount shown for "All Other Fees" in 2009 was for the assistance with loan review, non-compete agreements and tax credits. The Audit Committee pre-approved all services provided by the independent accountants during 2009.

The Audit Committee has considered whether the provision of these services is compatible with maintaining our principal auditors' independence. Following the adoption of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder, our independent auditors are proscribed from offering certain services to us. None of those proscribed services were provided to us in 2008 or 2009. None of the hours expended on Plante & Moran, PLLC's engagement to audit the Corporation's consolidated financial statements for the year ended December 31, 2009, were attributed to work performed by persons other than Plante & Moran, PLLC's full-time, permanent employees.

The Charter of the Audit Committee provides that the Audit Committee will administer the Corporation's policy regarding the approval of audit and non-audit services. Under that policy, the Audit Committee must pre‑approve all engagements of the Corporation's independent auditors. Before the end of the first quarter of each year, the independent auditors retention to audit the Corporation's financial statements, including the associated fee, is approved by the Audit Committee. At the same time, the Audit Committee will evaluate other known potential engagements of the independent auditors, including the scope of the work proposed to be performed and the proposed fees and approve or reject each service, taking into account whether the services are permissible under applicable law and the possible impact of each non-audit service on the independent auditors' independence from management. At each subsequent meeting of the Audit Committee, the Audit Committee will receive updates on the services actually provided by the independent auditors and management may present additional services for approval. The Audit Committee has delegated to the Chairperson of the Audit Committee the authority to evaluate and approve engagements on behalf of the Audit Committee in the event that the need arises for pre-approval between Audit Committee meetings. This might occur, for example, if the Corporation was proposing to execute a financing on an accelerated timetable. If the Chairperson so approves any such engagements, he or she is required to report that approval to the full Audit Committee at the next Audit Committee meeting.
