STOCK UNIT AGREEMENT

Restricted Stock Units		This grant is an award of restricted stock units in the number of units set forth on the cover sheet, and subject to the vesting and other conditions described below (the “RSUs”). Each RSU represents the right to receive one share of Stock, subject to the terms and conditions set forth in this Agreement and the Plan. Your RSUs may not be transferred, assigned, pledged or hypothecated, whether by operation of law or otherwise, nor may the RSUs be made subject to execution, attachment or similar process.
Vesting		Your RSUs will vest as to one hundred percent (100%) of the total number of RSUs covered by this grant, on the first anniversary of the grant, as shown on the cover sheet, except as otherwise provided below.
Delivery		As soon as practicable following the vesting of the RSUs hereunder, the Company will issue to you a share certificate for the shares of Stock to which such vested RSUs relate. In the alternative, the Company may use the book-entry method of share recordation to indicate your share ownership. You will have no further rights with regard to a RSU once the share of Stock related to such RSU has been issued.
Service Termination		In the event of the termination of your service as a director of the Company (a “Service Termination”) due to death, Disability, retirement or termination in connection with a change in control of the Company, any unvested RSUs held by you shall immediately vest. In the event of a Service Termination for any other reason, any unvested RSUs held by you shall immediately be deemed forfeited. (For purposes of clarification, these vesting provisions apply notwithstanding any different vesting provisions in the Plan.)
Withholding Taxes		You agree, as a condition of this grant, that you will make acceptable arrangements to pay any withholding or other taxes that may be due as a result of vesting in RSUs or delivery of Stock acquired under this grant. In the event that the Company determines that any federal, state, local or foreign tax or withholding payment is required relating to the vesting in RSUs or delivery of shares arising from this grant, the Company shall have the right to require such payments from you, withhold shares that would otherwise have been issued to you under this Agreement or withhold such amounts from other payments due to you from the Company or any Affiliate.
Shareholder Rights		You do not have any of the rights of a shareholder with respect to the RSUs.
Adjustments		In the event of a stock split, a stock dividend or a similar change in the Stock, the number of RSUs covered by this grant may be adjusted (and rounded down to the nearest whole number) pursuant to the Plan. Your RSUs shall be subject to the terms of the agreement of merger, liquidation or reorganization in the event the Company is subject to such corporate activity.
Applicable Law		This Agreement will be interpreted and enforced under the laws of the State of Delaware, other than any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.
The Plan		The text of the Plan is incorporated in this Agreement by reference. Certain capitalized terms used in this Agreement are defined in the Plan, and have the meaning set forth in the Plan.

If at any time you would prefer to receive paper copies of these documents, as you are entitled to receive, the Company would be pleased to provide copies.
