(14)                          Compliance with Section 409A.  This Agreement is subject to the following provisions in order to ensure compliance with Section 409A of the Internal Revenue Code of 1986, as amended (Section 409A”).

(a)                                 None of the compensation or other payments to Employee provided for in, or that may be made pursuant to, this Agreement are intended by the Parties to be deferred compensation within the meaning of Section 409A. Employer and Employee intend that, to the maximum extent possible, any amounts paid pursuant to this Agreement shall qualify as a short-term deferral or as separation pay exempt from Section 409A.

(b)                                 If any payment, compensation or other benefit provided to the Employee in connection with his employment termination is determined, in whole or in part, to constitute “nonqualified deferred compensation” within the meaning of Section 409A and the Employee is a specified employee as defined in Section 409A(2)(B)(i), no part of such payments shall be paid before the day that is six (6) months plus one (1) day after the date of termination.

(c)                                  The Parties acknowledge and agree that Section 409A and its application, if any, to the terms of this Agreement may be subject to change as additional guidance and regulations become available.  Anything to the contrary herein notwithstanding, all benefits or payments provided by the Employer to the Employee that would be deemed to constitute “nonqualified deferred compensation” within the meaning of Section 409A are intended to comply with Section 409A.  If, however, any such benefit or payment is deemed to not comply with Section 409A, the Employer and the Employee agree to renegotiate in good faith any such benefit or payment (including, without limitation, as to the timing of any severance payments payable hereof) so that either (i) Section 409A will not apply or (ii) compliance with Section 409A will be achieved.

(d)                                 Unless otherwise permitted under Section 409A, all in-kind benefits, expenses or other reimbursements paid pursuant to this Agreement that are taxable income to Employee (i) will be paid no later than the end of the calendar year next following the calendar year in which Employee incurs such expense; (ii) will not be subject to liquidation or exchange for another benefit; and (iii) the amount of expenses eligible for reimbursements or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year. For purposes of Section 409A, Employee’s right to receive any installment payments under this Agreement shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment.

(e)                                  All payments required to be made by Employer hereunder to the Employee may be adjusted to the withholding of such amounts, if any, relating to tax and other payroll deductions as Employer may reasonably determine should be withheld pursuant to any applicable law or regulation.

(15)                          Miscellaneous Provisions.  The following miscellaneous provisions shall apply to this Agreement:

(a)                                 All notices or advices required or permitted to be given by or pursuant to this Agreement, shall be given in writing.  All such notices and advices shall be (i) delivered personally or (ii) delivered for overnight delivery by a nationally recognized overnight courier service.  Such notices and advices shall be deemed to have been given (i) the first business day following the date of delivery if delivered personally or (ii) on the date of receipt if delivered for overnight delivery by a nationally recognized overnight courier service.  All such notices and advices and all other communications related to this Agreement shall be given as follows:

(d)                                 This Agreement, in conjunction with the Merger Agreement, is the entire Agreement of the Parties respecting the subject matter hereof.  There are no other agreements, representations or warranties, whether oral or written, respecting the subject matter hereof, except as stated in this Agreement or the Merger Agreement. For the avoidance of doubt, this Agreement shall not supersede, replace, or otherwise amend or affect the Amended and Restated Executive Split Dollar Life Insurance Agreement by and between the Employee and CoBiz Bank dated as of December 31, 2007. Without limiting the foregoing, as of the Effective Time, this Agreement shall irrevocably supersede and replace in its entirety the prior Employment Agreement by and between CoBiz, Inc. and the Employee dated as of November 19, 2004 (as amended) (as amended, the “Prior Employment Agreement”), which shall be irrevocably terminated at such time.  CoBiz Financial has executed this Agreement solely for purposes of agreeing and acknowledging that the Prior Employment Agreement has been irrevocably terminated, superseded and replaced in its entirety. Notwithstanding the foregoing or anything in this Agreement to the contrary, in the event that the Merger Agreement is terminated for any or no reason, this Agreement shall not become and shall be treated as never having become effective; the Parties will not be entitled to any of the rights, benefits or payments described under this Agreement; the Parties will not be subject to any of the obligations arising under this Agreement; and the Prior Employment Agreement shall continue to govern and be treated as having governed the terms and conditions of Employee’s employment with the Employer at all times following the initial execution of such Prior Employment Agreement.
