9. NONCOMPETITION, NONSOLICITATION AND NONDISCLOSURE:

(a) Executive hereby covenants and agrees that, for the period indicated below, following her termination of employment for any reason, she shall not, without the written consent of Company, either directly or indirectly:

(i) for a period of one (1) year, become an officer, employee, consultant, director, independent contractor, agent, joint venturer, partner or trustee of any business whatsoever that competes with the business of Company, the Bank or any Subsidiary other than the Bank in the United States.

(ii) for a period of two (2) years, solicit, offer employment to, or take any other action intended (or that a reasonable person acting in like circumstances would expect) to have the effect of causing any officer or employee of Company, the Bank or any Subsidiary other than the Bank to terminate her employment and accept employment or become affiliated with, or provide services for compensation in any capacity whatsoever to, any business whatsoever that competes with the business of Company, the Bank or any Subsidiary other than the Bank in the United States; or

(iii) for a period of two (2) years, solicit, provide any information, advice or recommendation or take any other action intended (or that a reasonable person acting in like circumstances would expect) to have the effect of causing any Protected Customer to terminate an existing business or commercial relationship with Company, the Bank or any Subsidiary other than the Bank.

(iv) For purposes of this Section 9(a), a business that “competes with the business of Company, the Bank or any Subsidiary other than the Bank” shall mean (a) Silicon Valley Bank, Comerica Bank, Bridge Bank, First Republic, Escalate Capital, Hercules Technology Growth Capital, Eastward Capital, NXT Capital, Triplepoint Capital, Horizon Technology Finance, Lighthouse Capital Partners, Oxford Finance Corporation, Pinnacle

Ventures, Sand hilt Finance or Western Technology Investment/Venture Lending & Leasing, (b) any other depository financial institution or venture debt fund engaged in (x) the solicitation and acceptance of deposits of money and commercial paper from the venture capital markets and venture financed portfolio companies, or (y) the solicitation and funding of loans and the provision of other banking services to the venture capital markets and venture financed portfolio companies, or (c) any other business engaged in by Company or the Bank as of Executive’s termination of employment which is related specifically to the venture capital markets.

Executive shall not, without the prior written consent of as applicable, Company, the Bank and such other Subsidiary or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than Company, the Bank and such other Subsidiary and those designated by them. After the end of the Restricted Period, the existence and identity of the customers and employees of Company, the Bank, and any Subsidiaries other than the Bank shall not constitute secret or confidential information, knowledge or data.

(d) The parties agree that the restrictions contained in this Section 9 are reasonable and fair. If Executive competes in violation of the terms of this Section 9, the parties agree that Company will be irreparably harmed without an adequate remedy at law. Accordingly, Executive acknowledges that if she breaches or threatens to breach any provision of this Section 9, Company shall be entitled to an injunction, both preliminary and permanent, restraining Executive from such breach or threatened breach, but such injunctive relief shall not preclude Company from pursuing all other legal or equitable remedies arising out of such a breach.

10. REFORMATION: The parties have attempted to limit Executive’s right to compete only to the extent necessary to protect Company, the Bank and Subsidiaries other than the Bank from unfair competition. The parties recognize, however, that reasonable people may differ in making such a determination. Consequently, the parties hereby agree that, if the scope or enforceability of a restrictive covenant set forth in Section 9 is in any way disputed at any time, a court or other trier of fact may modify and reform such provision to substitute such other terms as are reasonable to protect the legitimate business interests of Company, the Bank and Subsidiaries other than the Bank.

11. NOTICES: For the purposes of this Agreement, notices or other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when hand delivered to the party to whom directed or mailed by United States certified mail, return receipt requested, postage prepaid, addressed to such party at such party’s address last

known by the party giving such notice. Each party may, from time to time, and shall, upon request of another party, designate an address to which notices should be sent. Notices of change of address shall be effective only upon receipt.

12. MODIFICATION; WAIVERS; APPLICABLE LAW: No provisions of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing, signed by Executive, and on behalf of Company, by such officers as may be specifically designated by Company. No waiver of any breach, condition or provision of this Agreement by any party hereto at any time shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by any party which are not set forth expressly in this Agreement. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of North Carolina, except to the extent that federal law applies.

13. INVALIDITY; ENFORCEABILITY: The invalidity or enforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. Any provision in this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating or affecting the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

14. SUCCESSOR RIGHTS: This Agreement shall inure to the benefit of and be enforceable by Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees, and shall be binding upon Company and any successor to Company. If Executive should die while any amounts would still be payable to Executive hereunder all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to Executive’s devisee, legatee or other designee or, if there is no such designee, to Executive’s estate.

15. ATTORNEY’S FEES: Each party shall be responsible for any costs and fees (including attorney’s fees) it incurs in enforcing its rights under this Agreement.

EFFECT OF FEDERAL BANKING STATUTES AND REGULATIONS: Notwithstanding anything herein contained to the contrary, any payments to Executive by the Employer whether pursuant to this Agreement or otherwise, are subject to and conditioned upon their compliance with Section 18(k) of the Federal Deposit Insurance Act, 12 U.S.C. Section 1828(k), and the regulations promulgated thereunder in 12 C.F.R. Part 359. In addition, Executive agrees that this Agreement is subject to amendment at any time in order to comply with laws that are applicable to Company and the Bank (including regulations and rules relating to any governmental program in which Company or the Bank may participate).

17. HEADINGS: Descriptive headings contained in this Agreement are for convenience only and shall not control or affect the meaning or construction of any provision hereof.

18. EFFECT ON PRIOR AGREEMENTS: This Agreement shall supersede all prior agreements, either expressed or implied, between the parties hereto with respect to the employment of Executive.

19. INTERNAL REVENUE CODE SECTION 409A/CONTINUATION OF BENEFITS/REIMBURSEMENTS: This Agreement is intended to and shall comply with Section 409A of the Code. All references to a termination of employment and separation from service shall mean and be administered to comply with the definition of “separation from service” in Section 409A of the Code. All reimbursements provided under this Agreement shall comply with Section 409A of the Code and shall be subject to the following requirements:

(a) The amount of expenses eligible for reimbursement, during Executive’s taxable year may not affect the expenses eligible for reimbursement to be provided in another taxable year, and

If Executive is a “specified employee” (as defined under Section 409A of the Code) at the time of separation from service, to the extent that any amount payable under this Agreement constitutes “deferred compensation” under Section 409A of the Code (and is not otherwise excepted from Section 409A of the Code coverage by virtue of being considered “separation pay” or a “short term deferral” or otherwise) and is payable to Executive based upon a separation from service (other than death or “disability” as defined under Section 409A of the Code), such amount shall not be paid until the first day following the six (6) month anniversary of Executive’s separation from service. Any right to a series of installment payments shall be treated as a right to a series of separate payments for purposes of Section 409A of the Code. Payment of any accrued and unused paid time off, unless expressly provided otherwise herein shall be made in a single lump sum within thirty (30) days of separation from service.

20. Arbitration of Disputes: Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by binding arbitration, as an alternative to civil litigation and without any trial by jury to resolve such claims, conducted by a single arbitrator who is certified by the American Arbitration Association and is mutually acceptable to Executive and Company, sitting in a location selected by the Employer within fifty (50) miles from the main office of the Employer, in accordance with the rules of the American Arbitration Association’s National Rules for the Resolution of Employment Disputes then in effect. Judgment may be entered on the arbitrator’s award in any court having jurisdiction.

IN WITNESS WHEREOF, the parties have executed this Agreement effective as of the date first above written.
