1.01Grant of RSUs.

(a)The Company hereby grants the number of Restricted Stock Units to the Participant as specified in the Grant Notice (the “RSUs”), effective as of the Grant Date set forth in the Grant Notice (the “Grant Date”).

(b)Each RSU shall initially represent an unfunded, unsecured right to receive one share of the Company’s Common Stock (“Share”) or cash in lieu thereof pursuant to the terms and conditions of the Plan and this Agreement. As a holder of RSUs, the Participant has only the rights of a general unsecured creditor of the Company, unless and until settlement of the RSUs.

(c)All cash dividends and other distributions, including any dividend in Shares, made or declared with respect to the Company’s Shares (“Retained Distributions”) prior to the vesting of any RSU that has not otherwise been forfeited will be (i) subject to all restrictions placed on the Unvested RSUs (as herein defined) and (ii) held by the Company or its authorized representatives until the time (if ever) when the Unvested RSUs to which such Retained Distributions related become Vested RSUs. The Company will establish a separate bookkeeping account (“RSU Account”) for each Unvested RSU and credit the RSU Account on the date of payment with an amount equal to the Retained Distribution made on each Share for each Unvested RSU. Retained Distributions (including any Retained Distribution balance in the RSU Account) will immediately and automatically be forfeited upon forfeiture of the Unvested RSU with respect to which the Retained Distributions were paid or declared. No interest will be paid on any Retained Distributions.

1.02Incorporation of Terms of Plan. The RSUs are subject to the terms and conditions set forth in this Agreement and the Plan, each of which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control and govern.

1.03Defined Terms. Capitalized terms not specifically defined in this Agreement shall have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the Plan.

2.01Vesting of RSUs. Subject to the terms and conditions of the Plan and this Agreement, the RSUs will become vested (“Vested RSUs”) according to the Vesting Schedule in the Grant Notice (the “Vesting Schedule”), except that any fraction of a RSU which would be vested will be accumulated and will vest only when a whole Vested RSU has accumulated.

2.02Forfeiture. In the event Participant ceases to be an Outside Director for any reason (voluntary or involuntary), Participant will immediately and automatically forfeit to the Company any RSUs that are not Vested RSUs (the “Unvested RSUs”) at the time Participant ceases to be an Outside Director, except as otherwise determined by the Administrator or provided in a binding written agreement

between Participant and the Company. Upon forfeiture of Unvested RSUs, the Participant will have no further rights with respect to the Unvested RSUs.

2.03Settlement of RSUs. Settlement of each Vested RSU, together with any related Retained Distributions, shall be in cash or Shares, or any combination thereof, as determined by the Administrator. If settled in Shares, each Vested RSU shall represent the right to receive one Share. If settled in cash, each Vested RSU shall represent the right to receive cash in an amount equal to the Fair Market Value of a Share on the date of vesting. Any related Retained Distributions shall be distributed in cash or, at the discretion of the Administrator, in that number of Shares having an aggregate Fair Market Value on the date of vesting equal to the amount of the Retained Distribution related to the Vested RSUs. Any Shares delivered to or on behalf of Participant in exchange for Vested RSUs shall (i) be delivered on or prior to the Settlement Date (as herein defined) following the Vesting Date and (ii) be subject to any further transfer or other restrictions as may be required by securities law or other applicable law as determined by the Company. Any settlement in cash shall be made on or prior to the Settlement Date. For purpose of this Agreement, the “Settlement Date” shall be any business day within the thirty (30) calendar day period following each Vesting Date. Notwithstanding the preceding provisions of this Section 2.03, Participant may elect to defer the delivery of cash or Shares, as applicable, in settlement of the Vested RSUs and any related Retained Distributions pursuant to the Restricted Stock Unit Deferral Election Form attached hereto as Exhibit B. Any such election shall be made in compliance with such rules and procedures as the Administrator prescribes from time to time.

2.04No Stockholder Rights. RSUs do not entitle Participant to any rights of a stockholder of the Company. Such rights will only exist with regard to Shares issued to Participant in settlement of any Vested RSUs once Participant has become the holder of record of such Shares.

3.01Representation. Participant represents to the Company that Participant has had the opportunity to review with Participant’s own tax advisors the tax consequences of the RSUs and the transactions contemplated by the Grant Notice and this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Participant acknowledges that the Company does not have any tax withholding obligations with respect to the RSUs or upon vesting thereof.

4.01Adjustments. Participant acknowledges that the RSUs are subject to adjustment, modification and termination in certain events as provided in this Agreement and the Plan.

4.03Regulatory Restrictions on Shares. Notwithstanding the other provisions of this Agreement, if at any time the Administrator determines, in its sole discretion, that the listing, registration or qualification of Shares upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of any Shares hereunder to Participant (or his or her estate), such issuance will not occur unless and until such listing, registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. The Company shall be under no obligation to Participant to (i) register for offering or resale, (ii) qualify for exemption under federal securities law, (iii) register or qualify under the laws of any state or foreign jurisdiction, any Shares, security or interest in a security paid or issued under, or created by, the Plan, or (iv) continue in effect any such registrations or qualifications if made. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary or appropriate to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority has not been obtained.

4.04Conformity to Applicable Laws. Participant acknowledges that the Plan, the Grant Notice and this Agreement are intended to conform to the extent necessary with all Applicable Laws and, to the extent Applicable Laws permit, will be deemed amended as necessary in order to conform to Applicable Laws.

Any determination in this connection by the Administrator shall be final, binding, and conclusive. The obligations of the Company and the rights of Participant are subject to all Applicable Laws.

4.06Investment Representations. Unless the Shares are issued to Participant in a transaction registered under applicable federal and state securities laws, Participant represents and warrants to the Company that all Shares which may be received hereunder will be acquired by Participant for investment purposes for his or her own account and not with any intent for resale or distribution in violation of federal or state securities laws. Unless the Shares are issued to Participant in a transaction registered under the applicable federal and state securities laws, at the option of the Company, (i) a stop-transfer order against the Shares may be placed on the official stock books and records of the Company or at the transfer agent, and (ii) a legend indicating that such Shares may not be pledged, sold or otherwise transferred, unless an opinion of counsel is provided (concurred in by counsel for the Company) stating that such transfer is not in violation of any applicable law or regulation, may be stamped on a stock certificates to ensure exemption from registration. The Company may require such other action or agreement by Participant as may from time to time be necessary or appropriate to comply with the federal, state and foreign securities laws or other Applicable Laws.

4.07Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement will inure to the benefit of the successors and assigns of the Company.
