10.                               Confidentiality and Non-Competition.

(a)                                 The Executive acknowledges that he has had or will have unlimited access to the confidential information and business methods relating to the business and operations of the Employer and that those entities would be irreparably injured and their goodwill would be irreparably damaged if the Executive were to breach the covenants set forth in this Section 10. The Executive further acknowledges that the covenants set forth in this Section 10 are reasonable in scope and duration and do not unreasonably restrict the Executive’s association with other entities, either as an Executive or otherwise as set forth herein.

(b)                                 During the Term of Employment and thereafter, except as may be required by law or necessary in connection with any dealings with any public agency or authority, the Executive must not disclose, disseminate, divulge, discuss, copy or otherwise use or suffer to be used, in competition with, or in a manner harmful to the interests of, the Employer, any confidential information (written or oral) respecting any material aspect of Employer’s business, excepting only use of such data or information as is (i) at the time disclosed, through no act or failure to act on the part of the Executive, generally known or available; (ii) furnished to the Executive by a third party as a matter of right and without restriction on disclosure; or (iii) required to be disclosed by court order. Upon termination of the Term of Employment, the Executive shall return to the Employer any and all materials in tangible or electronic form containing confidential information belonging to the Employer.

(c)                                  During the Term of Employment and for one (1) year thereafter, the Executive must not in the states in which the Employer then regularly conducts business, directly or indirectly, whether as an individual on the Executive’s own account, or as a shareholder, partner, member, joint venturer, director, officer, employee, consultant, creditor and/or agent, of any person, firm or organization or otherwise:

(i)                                     employ, assist in employing or otherwise associate in business with any employee or officer of the Employer that is, or was during the twelve-month period immediately prior to the termination of the Executive’s employment, employed by the Employer, other than an employee or an officer who is a relative of the Executive by blood or marriage;

6

(ii)                                  solicit or encourage any individual or entity that is, or was during the twelve-month period immediately prior to the termination of Executive’s employment with the Employer for any reason, a customer or vendor of the Employer to terminate or otherwise alter his, her or its relationship with the Employer; provided, however, that notwithstanding anything to the contrary, the parties agree that this Section 10 does not prohibit the Executive from pursuing or establishing a business relationship with any current or former customer or vendor of the Employer where such customer or vendor presents himself, herself or itself to Executive unsolicited by him;

(iii)                               induce any person who is a present or future employee, officer, agent, affiliate or customer of the Employer to terminate the relationship; or

(iv)                              engage in disparagement (which will not include the providing of accurate information without invidious intent) of the Employer by any means to any person.

11.                               Rights and Remedies Upon Breach.

(a)                                 The Executive expressly agrees and understands that the remedy at law for any breach by the Executive of Section 10 will be inadequate and that the damages flowing from such breach are not readily susceptible to being measured in monetary terms. Accordingly, it is acknowledged that upon adequate proof of the Executive’s violation of Section 10, the Employer will be entitled, among other remedies, to injunctive relief and may obtain a temporary restraining order restraining any threatened or further breach. Nothing in this Section 11(a) will be deemed to limit the Employer’s remedies at law or in equity for any breach by the Executive of any of the provisions of this Agreement which may be pursued or availed of by the Employer.

(b)                                 In the event any arbitrator or court of competent jurisdiction determines that the specified time period or geographical area set forth in Section 10 is unreasonable, arbitrary or against public policy, then a lesser time period or geographical area that is determined by the court to be reasonable, non-arbitrary and not against public policy may be enforced.

(c)                                  In the event the Employer has asserted in a formal legal action, including arbitration, that the Executive is violating any legally enforceable provision of Section 10 as to which there is a specific time period during which the Executive is prohibited from taking certain actions or engaging in certain activities, then, in such event the violation will toll the running of the time period from the date of the assertion until the violation ceases.

12.                               Withholding Taxes.  All payments to the Executive or his beneficiary will be subject to withholding on account of federal, state and local taxes as required by law. If any payment hereunder is insufficient to provide the amount of such taxes required to be withheld, the Employer may withhold such taxes from any other payment due the Executive or his beneficiary.

7

13.                               Assignability; Binding Nature.  This Agreement will be binding upon and inure to the benefit of the Parties and their respective successors, heirs (in the case of the Executive) and assigns. No rights or obligations of the Employer under this Agreement may be assigned or transferred except that such rights or obligations may be assigned or transferred pursuant to (i) a merger or consolidation in which the Employer is not the continuing entity or (ii) a sale or liquidation of all or substantially all of the assets of the Employer, provided that the assignee or transferee is the successor to all or substantially all of the assets of the Employer and such assignee or transferee assumes the liabilities, obligations and duties of the Employer, as contained in this Agreement, either contractually or as a matter of law. The Employer further agrees that, in the event of a sale of assets or liquidation as described in the preceding sentence, it will use its best efforts to cause such assignee or transferee to expressly assume the liabilities, obligations and duties of the Employer hereunder. No obligations of the Executive under this Agreement may be assigned or transferred by the Executive.

14.                               Bank Regulatory Requirements Compliance Terms.  Due to federal regulatory requirements binding upon the Employer, Parties hereby acknowledge and agree to the following statutorily mandated terms:

(a)                                 The Bank’s board of directors may terminate this Agreement at any time, but any termination by the Bank’s Board of Directors other than termination for cause, shall not prejudice the Executive’s right to compensation or other benefits under the agreement. The Executive shall have no right to receive compensation or other benefits for any period after termination for cause. Termination for cause shall include termination because of the officer or employee’s personal dishonesty, incompetence, willful misconduct, breach of fiduciary duty involving personal profit, intentional failure to perform stated duties, willful violation of any law, rule, or regulation (other than traffic violations or similar offenses) or final cease-and-desist order, or material breach of any provision of the contract.

(b)                                 If the Executive is suspended and/or temporarily prohibited from participating in the conduct of the Employer’s affairs by a notice served under section 8 (e) (3) or (g) (1) of Federal Deposit Insurance Act (12 U.S.C. 1818 (e) (3) and (g) (1)) the Bank’s obligations under this Agreement shall be suspended as of the date of service unless stayed by appropriate proceedings. If the charges in the notice are dismissed, the Employer may in its discretion (i) pay the Executive all or part of the compensation withheld while its Agreement obligations were suspended, and (ii) reinstate (in whole or in part) any of its obligations which were suspended.

(c)                                  If the Executive is removed and/or permanently prohibited from participating in the conduct of the Employer’s affairs by an order issued under section 8 (e) (4) or (g) (1) of the Federal Deposit Insurance Act (12 U.S.C. 1818 (e) (4) or (g) (1)), all obligations of the Employer under this Agreement shall terminate as of the effective date of the order, but vested rights of the contracting parties shall not be affected.

date of default, but this paragraph (b)(4) shall not affect any vested rights of the contracting parties.

(e)                                  All obligations under this Agreement shall be terminated, except to the extent determined that continuation of the Agreement is necessary for the continued operation of the Employer:

(i)                                     By the Director or his or her designee, at the time the Federal Deposit Insurance Corporation enters into an agreement to provide assistance to, or on behalf of, the association under the authority contained in 13(c) of the Federal Deposit Insurance Act; or

(ii)                                  By the Director or his or her designee, at the time the Director or his or her designee approves a supervisory merger to resolve problems related to operation of the association or when the association is determined by the Director to be in an unsafe or unsound condition.

Any rights of the parties that have already vested, however, shall not be affected by such action.

15.                               Governing Law, Arbitration and Waiver of Jury Trial.  The Parties agree, to the extent permitted by law, that they EACH HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY, and agrees not to bring any claim, proceeding or action arising out of or related to this Agreement in any tribunal or court, except as necessary to enforce the provisions of Section 10 of this Agreement, mandate arbitration as provided in this section, or enforce an arbitration award rendered pursuant to this Agreement. Any and all disputes related to this Agreement or to the parties’ performance hereunder, including but not limited to any dispute alleging that this Agreement was obtained by misrepresentation or mistake, will be submitted for resolution into Arbitration with the American Arbitration Association (“AAA”), in San Francisco, California, to be conducted under then applicable commercial rules promulgated by the AAA. Notwithstanding the above, the Employer may seek injunctive relief in a California court of competent jurisdiction, to enjoin any breach or anticipatory breach of the Executive’s obligations as set forth in paragraphs 8 and 9 of this Agreement, pending the outcome of an Arbitration of their dispute. The parties further agree and acknowledge that the Executive is a resident of the State of California and that the Company is a resident of the State of Michigan for traditional jurisdiction and venue purposes, but they are nevertheless voluntarily agreeing to an arbitration venue and personal jurisdiction in the State of California for their mutual convenience. California law will be applied to the resolution of any dispute related to this Agreement.

other Party of any condition or provision contained in this Agreement to be performed by such other Party will be deemed a waiver of a similar or dissimilar condition or provision at the same or any prior or subsequent time.
