TERMS AND CONDITIONS

1. INTRODUCTION

Pursuant to the Grant Notice to which these Terms and Conditions are attached, the Company has granted to Participant the right to receive the number of RSUs set forth in the Grant Notice, subject to all of the terms and conditions set forth in these Terms and Conditions, the Grant Notice and the Plan.  In the event of any inconsistency between the terms of the Plan and these Terms and Conditions, the terms of the Plan will control.

2. AWARD OF RESTRICTED STOCK UNITS

In consideration of Participant’s service as a Director of the Company and for other good and valuable consideration, the Company hereby grants to Participant the number of RSUs set forth in the Grant Notice. Prior to the actual issuance of any Shares, the Award represents an unsecured obligation of the Company, payable only from the general assets of the Company.  

3. Vesting and forfeiture.

(a) The RSUs will be fully vested as of the Grant Date  

(b) Notwithstanding the foregoing, all of the RSUs will be forfeited in the event of the commission by Participant of an “Act of Misconduct” prior to payment of the RSUs.  For purposes of the Award, an “Act of Misconduct” means the occurrence of one or more of the following events: (i) Participant uses for profit or discloses to unauthorized persons, confidential information or trade secrets of the Company or any of its Subsidiaries, or (ii) Participant breaches any contract with or violates any fiduciary obligation to the Company or any of its Subsidiaries.

4. Distribution of RSUs.

Shares of Common Stock shall be distributed to Participant (or in the event of Participant’s death, to his or her estate) with respect to Participant’s vested RSUs as provided in Exhibit B. All distributions of the RSUs shall be made by the Company in the form of whole shares of Common Stock.  No fractional Shares shall be issued and in the event any fractional Shares result from any adjustment to the RSUs pursuant to the Plan, the resulting RSUs shall be rounded down to the nearest whole Share (other than fractional Shares resulting from the payment of the RSUs in installments pursuant to Exhibit B, in which case any such fractional Shares shall be satisfied in cash based on the Fair Market Value of a Share on the date such Share would otherwise have been distributed to Participant).  

A-2

5.Tax Withholding.

(a) The Company shall not be obligated to deliver any certificate representing Shares issuable with respect to the RSUs unless and until Participant or his or her legal representative shall have paid or otherwise satisfied in full the amount of all federal, state, local and foreign taxes (including Participant's social security, Medicare and any other employment tax obligation) required by Applicable Law to be withheld with respect to the taxable income of Participant resulting from the vesting of the RSUs, the distribution of the Shares issuable with respect thereto, or any other taxable event related to the Award (the “Tax Withholding Obligation”).  

(b) Participant’s acceptance of this Award constitutes Participant’s instruction and authorization to the Company to, and the Company shall, withhold a net number of vested Shares otherwise issuable pursuant to the RSUs having a then-current Fair Market Value not exceeding the amount necessary to satisfy the Tax Withholding Obligation of the Company and its Subsidiaries with respect to the vesting or distribution of the RSUs.    

(c) To the maximum extent permitted by Applicable Law, the Company further has the authority to deduct or withhold such amount as is necessary to satisfy any Tax Withholding Obligation from other compensation payable to Participant with respect to any taxable event arising from vesting of the RSUs, the receipt of the Shares upon settlement of the RSUs or any other taxable event relating to the Award.  

(d) Subject to Section 10.2 of the Plan, the applicable Tax Withholding Obligation will be determined based on Participant's Applicable Tax Withholding Rate.  Participant's “Applicable Tax Withholding Rate” shall mean the greater of (i) the minimum applicable statutory tax withholding rate or (ii) with Participant’s consent, the maximum individual tax withholding rate permitted under the rules of the applicable taxing authority for tax withholding attributable to the underlying transaction; provided, however, that in no event shall Participant’s Applicable Tax Withholding Rate exceed the maximum individual statutory tax rate in the applicable jurisdiction at the time of such withholding (or such other rate as may be required to avoid the liability classification of the applicable award under generally accepted accounting principles in the United States of America); provided, however, that the number of Shares tendered or withheld, if applicable, pursuant to clause (b) shall be rounded up to the nearest whole Share sufficient to cover the applicable Tax Withholding Obligation, to the extent rounding up to the nearest whole Share does not result in the liability classification of the RSUs under generally accepted accounting principles.

6. Award Not Transferable.

This Award shall be subject to the restrictions on transferability set forth in Section 10.3 of the Plan.  Subject to the foregoing restrictions on transfer, the Plan, the Grant Notice and these Terms and Conditions shall be binding upon Participant and his or her heirs, executors, administrators, successors and assigns.

The Administrator may, in its discretion, adopt such amendments to the Plan, these Terms and Conditions or the Grant Notice or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, as the Administrator determines are necessary or appropriate to comply with the requirements of Section 409A. For purposes of Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), each payment that Participant may be eligible to receive under this Award shall be treated as a separate and distinct payment. Neither the time nor form of distribution of Shares with respect to the RSUs may be changed, except as may be permitted by the Administrator in accordance with the Plan and Section 409A of the Code and the Treasury Regulations thereunder.  For purposes of these Terms and Conditions, all references to Participant’s termination of service with the Company or termination as a member of the Board shall mean a “separation from service” as defined in Code Section 409A and Treasury Regulations Section 1.409A-1(h) without regard to the optional alternative definitions available thereunder.  If Participant is a “specified employee” (as determined in accordance with Section 409A(a)(2)(B)(i) of the Code and Treasury Regulation Section 1.409A-1(i)) on the date of Participant's “separation from service", the delivery of any of Common Stock to be delivered upon such “separation from service” shall be delayed to the extent necessary to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, and such payment shall be paid or distributed to Participant on the earlier of (a) the expiration of the six-month period measured from the date of Participant's “separation from service” or (b) the date of Participant's death.
