All questions of interpretation concerning the Notice of Award, this Agreement, the Plan or any other form of agreement or other document employed by the Company in the administration of the Plan or the Award shall be determined by the Committee. All determinations by the Committee shall be final and binding upon all persons having an interest in the Award. Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, or election.

3.    THE AWARD.

3.1    Grant of Restricted Stock Units. On the Date of Award, the Participant shall acquire, subject to the provisions of this Agreement, the Number of Restricted Stock Units set forth in the Notice of Award, subject to adjustment as provided in Section 3.3 and Section 9. Each Unit represents a right to receive on a date determined in accordance with the Notice of Award and this Agreement one (1) share of Stock.

3.2    No Monetary Payment Required. The Participant is not required to make any monetary payment (other than to satisfy applicable tax withholding, if any, with respect to the vesting of the Units, or issuance of shares of Stock) as a condition to receiving the Units or shares of Stock issued upon settlement of the Units, the consideration for which shall be past services actually rendered and/or future services to be rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable state corporate law, the Participant shall furnish consideration in the form of cash or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the shares of Stock issued upon settlement of the Units.

3.3    Dividend Equivalent Units. On the date that the Company pays a cash dividend to holders of Stock generally, the Participant shall be credited with a number of additional whole Dividend Equivalent Units determined by dividing (a) the product of (i) the dollar amount of the cash dividend paid per share of Stock on such date and (ii) the total number of Vested Units and Dividend Equivalent Units previously credited to the Participant pursuant to the Award and which have not been settled or forfeited pursuant to the Company Reacquisition Right (as defined below) as of such date, by (b) the Fair Market Value per share of Stock on such date. Any resulting fractional Dividend Equivalent Unit shall be rounded to the nearest whole number. Such additional

Dividend Equivalent Units shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the Restricted Stock Units originally subject to the Award with respect to which they have been credited.

4.    VESTING OF UNITS.

4.1    Normal Vesting. Except as otherwise provided by this Section or Section 4.2, Units shall vest and become Vested Units as provided in the Notice of Award. Dividend Equivalent Units shall become Vested Units at the same time as the Restricted Stock Units originally subject to the Award with respect to which they have been credited. In the event that a Vesting Date as provided by the Notice of Award (an “Original Vesting Date”) would occur on a date on which a sale by the Participant of the Stock to be issued in settlement of the Units becoming Vested Units on such Original Vesting Date would violate the Insider Trading Policy of the Company, such Vesting Date shall be deferred until the first to occur of (a) the next business day on which a sale by the Participant of such shares would not violate the Insider Trading Policy or (b) the later of (i) the last day of the calendar year in which the Original Vesting Date occurred or (ii) the last day of the Company’s taxable year in which the Original Vesting Date occurred.

4.2    Acceleration of Vesting Upon a Change in Control. In the event of a Change in Control, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the “Acquiror”), may assume or continue the Company’s rights and obligations with respect to outstanding Units or substitute for outstanding Units substantially equivalent rights with respect to the Acquiror’s stock. For purposes of this Section 4.2, a Unit shall be deemed assumed if, following the Change in Control, the Unit confers the right to receive, for each share of Stock subject to the Unit immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled. In the event that the Acquiror elects not to assume, continue or substitute for the outstanding Units in connection with a Change in Control, the vesting of the Units shall be accelerated in full and the total number of Units subject to the Award shall be deemed Vested Units effective as of the date of the Change in Control, provided that the Participant’s Service has not terminated prior to such date. The vesting Units that were permissible solely by reason of this Section 4.2 shall be conditioned upon the consummation of the Change in Control. Notwithstanding the foregoing, the Board may, in its discretion, determine that upon a Change in Control, each Vested Unit (and each unvested Unit if so determined by the Board) outstanding immediately prior to the Change in Control shall be canceled in exchange for payment with respect to each Unit in (a) cash, (b) stock of the Company or the Acquiror or (c) other property which, in any such case, shall be in an amount having a Fair Market Value equal to the Fair Market Value of the consideration to be paid per share of Stock in the Change in Control (subject to any required tax withholding). Such payment shall be made as soon as practicable following the Change in Control and in no event later than the fifteenth (15th) day of the third month following the end of the calendar year of the consummation of the Change in Control.

4.3    Acceleration of Vesting upon Termination After Change in Control. If the Participant’s Service ceases as a result of a Termination After Change in Control, then the vesting

of the Units shall be accelerated in full and the total number of Units subject to the Award shall be deemed Vested Units effective as of the date on which the Participant’s Service terminated.

4.4    Federal Excise Tax Under Section 4999 of the Code.

(a)    Excess Parachute Payment. In the event that any acceleration of vesting pursuant to this Agreement and any other payment or benefit received or to be received by the Participant would subject the Participant to any excise tax pursuant to Section 4999 of the Code due to the characterization of such acceleration of vesting, payment or benefit as an excess parachute payment under Section 280G of the Code, the amount of any acceleration of vesting called for under this Agreement shall not exceed the amount which produces the greatest after-tax benefit to the Participant.

(b)    Determination by Independent Accountants. Upon the occurrence of any event that might reasonably be anticipated to give rise to the acceleration of vesting under Section 4.4(a) (an “Event”), the Company shall promptly request a determination in writing by independent public accountants selected by the Company (the “Accountants”). Unless the Company and the Participant otherwise agree in writing, the Accountants shall determine and report to the Company and the Participant within twenty (20) days of the date of the Event the amount of such acceleration of vesting, payments and benefits which would produce the greatest after-tax benefit to the Participant. For the purposes of such determination, the Accountants may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Participant shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make their required determination. The Company shall bear all fees and expenses the Accountants may reasonably charge in connection with their services contemplated by this Section 4.4(b).

5.    COMPANY REACQUISITION RIGHT.

5.1    Grant of Company Reacquisition Right. In the event that the Participant’s Service terminates for any reason or no reason, with or without Cause, the Participant shall forfeit and the Company shall automatically reacquire all Units which are not, as of the time of such termination, Vested Units, and the Participant shall not be entitled to any payment therefor (the “Company Reacquisition Right”), subject to the provisions of any employment, service or other agreement between the Participant and a Participating Company referring to this Award.

5.2    Ownership Change Event, Dividends, Distributions and Adjustments. Upon the occurrence of an Ownership Change Event, a dividend or distribution to the stockholders of the Company paid in shares of Stock or other property, or any other adjustment upon a change in the capital structure of the Company as described in Section 9, any and all new, substituted or additional securities or other property (other than regular, periodic dividends paid on Stock pursuant to the Company’s dividend policy) to which the Participant is entitled by reason of the Participant’s ownership of Unvested Units shall be immediately subject to the Company Reacquisition Right and included in the terms “Units” and “Unvested Units” for all purposes of the Company Reacquisition Right with the same force and effect as the Unvested Units immediately prior to the Ownership Change Event, dividend, distribution or adjustment, as the case may be. For purposes

of determining the number of Vested Units following an Ownership Change Event, dividend, distribution or adjustment, credited Service shall include all Service with any corporation which is a Participating Company at the time the Service is rendered, whether or not such corporation is a Participating Company both before and after any such event.

6.    SETTLEMENT OF VESTED UNITS.

6.1    Issuance of Shares of Stock. Subject to the provisions of Section 6.3 below, the Company shall issue to the Participant, on the Settlement Date with respect to each Vested Unit to be settled on such date, one (1) share of Stock. Shares of Stock issued in settlement of Vested Units shall not be subject to any restriction on transfer other than any such restriction as may be required pursuant to Section 6.3, Section 7 or the Insider Trading Policy.

6.2    Beneficial Ownership of Shares; Certificate Registration. The Participant hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice any or all shares acquired by the Participant pursuant to the settlement of Vested Units. Except as provided by the preceding sentence, a certificate for the shares of Stock as to which the Award is settled shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant.

6.3    Restrictions on Grant of the Award and Issuance of Shares. The grant of the Award and issuance of shares of Stock upon settlement of the Vested Units shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. No shares of Stock may be issued hereunder if the issuance of such shares would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of any shares subject to the Award shall relieve the Company of any liability in respect of the failure to issue such shares as to which such requisite authority shall not have been obtained. As a condition to the settlement of the Vested Units, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

6.4    Fractional Shares. The Company shall not be required to issue fractional shares upon the settlement of the Vested Units.

7.    TAX WITHHOLDING.

7.1    In General. At the time the Notice of Award is executed, or at any time thereafter as requested by a Participating Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company, if any, which arise in connection with the Award or the issuance of shares of Stock in settlement thereof. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Company have been satisfied by the Participant.

7.2    Assignment of Sale Proceeds. Subject to compliance with applicable law and the Insider Trading Policy, the Company may require the Participant to satisfy the tax withholding obligations in accordance with procedures established by the Company providing for delivery by the Participant to the Company or a broker approved by the Company of properly executed instructions, in a form approved by the Company, providing for the assignment to a Participating Company of the proceeds of a sale with respect to some or all of the shares being acquired upon settlement of Vested Units.

7.3    Withholding in Shares. The Company may require the Participant to satisfy all or any portion of a Participating Company’s tax withholding obligations by deducting from the shares of Stock otherwise deliverable to the Participant in settlement of the Award a number of whole shares having a fair market value, as determined by the Company as of the date on which the tax withholding obligations arise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum statutory withholding rates.

8.    EFFECT OF CHANGE IN CONTROL ON AWARD.

In the event of a Change in Control, if the Company’s rights and obligations with respect to outstanding Vested Units are not assumed, continued or substituted for by the Acquiror as described in Section 4.2, the Award shall be settled in accordance with Section 6 and in no event later than the fifteenth (15th) day of the third month following the end of the calendar year of the consummation of the Change in Control.

9.    ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.

Subject to any required action by the stockholders of the Company, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number of Vested Units subject to the Award and/or the number and kind of shares to be issued in settlement of the Award, in order to prevent dilution or enlargement of the Participant’s rights under the Award. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any and all, new, substituted or additional securities or other property to which the Participant is entitled by reason of ownership to shares acquired pursuant to the Award will be immediately subject to the provisions of this Award on the same basis as all shares originally acquired hereunder. Any fractional Vested Unit or share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number. Such adjustments shall be determined by the Committee, and its determination shall be final, binding and conclusive.

10.    RIGHTS AS A STOCKHOLDER, DIRECTOR, EMPLOYEE OR CONSULTANT.

The Participant shall have no rights as a stockholder with respect to any shares which may be issued in settlement of this Award until the date of the issuance of a certificate for such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 3.3 and Section 9. If the Participant is an Employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, written employment agreement between a Participating Company and the Participant, the Participant’s employment is “at will” and is for no specified term. Nothing in this Agreement shall confer upon the Participant any right to continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Participant’s Service at any time.

11.    LEGENDS.

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock issued pursuant to this Agreement. The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to this Award in the possession of the Participant in order to carry out the provisions of this Section.

No amendment or addition to this Agreement shall be effective unless in writing.

12.2    Nontransferability of the Award. Prior the issuance of shares of Stock on the applicable Settlement Date, neither this Award nor any Vested Units subject to this Award shall be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. All rights with respect to the Award shall be exercisable during the Participant’s lifetime only by the Participant or the Participant’s guardian or legal representative.
