Each Option that is granted to an Eligible Director who has not as of the date of grant provided three (3) years of prior continuous service as an Eligible Director shall be fully vested as of the date upon which such Eligible Director has provided one year of continuous service on the Board as an Eligible Director following the date of grant of such Option. If the Eligible Director’s relationship as a director of the Company or an Affiliate is terminated by reason of the Eligible Director’s death or disability (within the meaning of Title II or XVI of the Social Security Act or comparable statute applicable to an Affiliate and with such permanent and total disability certified by (i) the Social Security Administration, (ii) the comparable governmental authority applicable to an Affiliate, (iii) such other body having the relevant decision-making power applicable to an Affiliate, or (iv) an independent medical advisor appointed by the Company, as applicable, prior to such termination), then the vesting schedule of each Option granted to such Eligible Director shall be accelerated by twelve months for each full year the Eligible Director has been affiliated with the Company and/or an Affiliate.

Securities Act; or (y) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities law.

ARTICLE IV

RESTRICTED STOCK UNITS

4.1 Annual Grants. On the date which is two business days after the release of the Company’s quarterly earnings for the first fiscal quarter of each year after the Effective Date, each person who is at that time an Eligible Director shall automatically be granted, without further action by the Company, the Board, or the Company’s stockholders, Restricted Stock Units to acquire a number of shares of Common Stock (rounded down to the nearest whole number) equal to the quotient obtained by dividing (x) $100,000, by (y) the closing market price of a share of Common Stock on the date of grant (rounded to two decimal places). Should the date of grant set forth in this Section 4.1 be a Saturday, Sunday or legal holiday, such grant shall be made on the next business day. Restricted Stock Units shall constitute Restricted Stock Units under Section 9.5 of the 2009 Plan.

4.2 Terms of Restricted Stock Units.

(a) Each Restricted Stock Unit granted pursuant to this Program shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Restricted Stock Units need not be identical, but each Restricted Stock Unit shall include (through incorporation of provisions hereof by reference in the Restricted Stock Unit agreement or otherwise) the substance of each of the following provisions as set forth this Section 4.2 and Section 9.5 of the 2009 Plan.

(b) Each grant of Restricted Stock Units made to an Eligible Director who has as of the date of grant provided three (3) years of prior continuous service on the Board as an Eligible Director shall be fully vested as of the date of grant and each grant of Restricted Stock Units that is made to an Eligible Director who has not as of the date of grant provided three (3) years of prior continuous service as an Eligible Director shall be fully vested as of the date upon which such Eligible Director has provided one year of continuous service on the Board as an Eligible Director following the date of grant of such Restricted Stock Units (in each case, such date of vesting the “Vesting Date”). If the Eligible Director’s relationship as a director of the Company or an Affiliate is terminated by reason of the Eligible Director’s death or total and permanent disability (as certified by an independent medical advisor appointed by the Company prior to such termination) and in a manner constituting a “separation from service” within the meaning of Code Section 409A, then a prorated number (rounded down to the nearest whole number) of unvested Restricted Stock Units, if any, shall vest immediately upon such death or disability, determined by multiplying the number of unvested Restricted Stock Units, if any, by a fraction (rounded to two decimal places), the numerator of which is the number of complete months of continuous service during the one year period following the date of grant and the denominator of which is 12.

4

(c) A holder’s vested Restricted Stock Units shall be paid by the Company in shares of Common Stock (on a one-to-one basis) on, or as soon as practicable after, the Vesting Date (the “Payment Date”), but in any event by the fifteenth day of the third month following the end of the tax year in which such Restricted Stock Units vest, unless the Eligible Director has irrevocably elected in writing by December 31 of the year preceding the grant of such Restricted Stock Units to defer the payment of such Restricted Stock Units, and any dividends paid thereon, to another date under one of the following options, which payment form or forms (including payment upon death or disability as provided above) shall be specified at the time of the deferral election (the “Deferred Payment Date”): (i) full payment of the vested Restricted Stock Units in January of a year specified by the Eligible Director which shall be no earlier than the third calendar year following the calendar year in which the date of grant occurs and no later than the tenth calendar year following such year; (ii) full payment of the vested Restricted Stock Units in January of the calendar year following the year in which the Eligible Director with respect to whom the Restricted Stock Units were granted ceases to be an Eligible Director and ceases to otherwise provide services to the Company in a manner that constitutes a “separation from service” (within the meaning of Code Section 409A) for any reason; (iii) payment of the vested Restricted Stock Units in five substantially equal annual installments, commencing in January of the calendar year following the year in which the Eligible Director with respect to whom the Restricted Stock Units were granted ceases to be an Eligible Director and ceases to otherwise provide services to the Company in a manner that constitutes a “separation from service” (within the meaning Code Section 409A) for any reason; or (iv) payment of the vested Restricted Stock Units in ten substantially equal annual installments, commencing in January of the calendar year following the year in which the Eligible Director with respect to whom the Restricted Stock Units were granted ceases to be an Eligible Director and ceases to otherwise provide services to the Company in a manner that constitutes a “separation from service” (within the meaning Code Section 409A) for any reason. Shares of Common Stock issued in respect of a Restricted Stock Unit shall be deemed to be issued in consideration for future services to be rendered or past services actually rendered to the Company or for its benefit, by the Eligible Director, which the Board deems to have a value not less than the par value of a share of Common Stock.

4.3 Dividend Equivalents.

(a) Crediting and Payment of Dividend Equivalents. Subject to this Section 4.3, Dividend Equivalents shall be credited on each Restricted Stock Unit granted to an Eligible Director under the Program in the manner set forth in the remainder of this Section 4.3. If the Company declares one or more dividends or distributions (each, a “Dividend”) on its Common Stock with a record date which occurs during the period commencing on the date of grant through and including the day immediately preceding the day the shares of Common Stock subject to the Restricted Stock Units are issued to the Eligible Director, whether in the form of cash, Common Stock or other property, then on the date such Dividend is paid to the Company’s stockholders the Eligible Director shall be credited with an amount equal to the amount or fair market value of such Dividend which would have been payable to the Eligible Director if the Eligible Director held a number of shares of Common Stock equal to the number of the Eligible Director’s Restricted Stock Units as of the record date for such

5

Dividend, unless the Restricted Stock Units have been forfeited between the record date and payment date for such Dividend. Any such Dividend Equivalents shall be credited and deemed reinvested in the Common Stock as of the Dividend payment date. Dividend Equivalents shall be payable in full shares of Common Stock, unless the Board determines, at any time prior to payment and in its discretion, that they shall be payable in cash. Dividend Equivalents payable with respect to fractional shares of Common Stock shall be paid in cash.

(b) Treatment of Dividend Equivalents. Except as otherwise expressly provided in this Section 4.3, any Dividend Equivalents credited to an Eligible Director shall be subject to all of the provisions of the Program and the Restricted Stock Unit Agreement which apply to the Restricted Stock Units with respect to which they have been credited and shall be payable, if at all, at the time and to the extent that the underlying Restricted Stock Unit becomes payable. Dividend Equivalents shall not be payable on any Restricted Stock Units that do not vest, or are forfeited, pursuant to the terms of this Agreement.

ARTICLE V

MISCELLANEOUS

5.1 Administration of the Program. The Program shall be administered by the Board.

5.2 Application of 2009 Plan. The Program is subject to all the provisions of the 2009 Plan, including Section 13.2 thereof (relating to adjustments upon changes in the Common Stock), and its provisions are hereby made a part of the Program, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the 2009 Plan. In the event of any conflict between the provisions of this Program and those of the 2009 Plan, the provisions of the 2009 Plan shall control.

5.3 Amendment and Termination. Notwithstanding anything herein to the contrary, the Board may, at any time, terminate, modify or suspend the Program; provided, however, that, without the prior consent of the Eligible Directors affected, no such action may adversely affect any rights or obligations with respect to any Awards theretofore earned but unpaid, whether or not the amounts of such Awards have been computed and whether or not such Awards are then payable. Any amendment of this Program may, in the sole discretion of the Board, be accomplished in a manner calculated to cause such amendment not to constitute an “extension,” “renewal” or “modification” (each within the meaning of Code Section 409A) of any Restricted Stock Units that would cause such Restricted Stock Units to be considered “nonqualified deferred compensation” (within the meaning of Code Section 409A).

5.4 No Contract for Employment. Nothing contained in the Program or in any document related to the Program or to any Award shall confer upon any Eligible Director any right to continue as a director or in the service or employment of the Company or an Affiliate or constitute any contract or agreement of service or employment for a specific term or interfere in any way with the right of the Company or an Affiliate to reduce such person’s compensation, to change the position held by such person or to terminate the service of such person, with or without cause.

6

5.5 Nontransferability.

(a) No benefit payable under, or interest in, this Program shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge and any such attempted action shall be void and no such benefit or interest shall be, in any manner, liable for, or subject to, debts, contracts, liabilities or torts of any Eligible Director or beneficiary; provided, however, that, nothing in this Section 6.5 shall prevent transfer (i) by will, (ii) by applicable laws of descent and distribution, (iii) to an Alternate Payee to the extent that a QDRO so provides, or (iv) of any Non-Qualified Stock Option, which is granted after December 10, 2007 or any Non-Qualified Stock Option which is outstanding on December 10, 2007 and which has an exercise price which is not less than one hundred percent (100%) of the fair market value of the Common Stock subject to the Non-Qualified Stock Option as of such date, to a trust for which the Eligible Director grantor is a trustee of the trust or a beneficiary of the trust with investment control over the trust assets and which trust qualifies as a “family member” of the Eligible Director, as defined under the instructions to use of the Form S-8 Registration Statement under the Securities Act (a “Trust”).

(b) The transfer to an Alternate Payee of an Award pursuant to a QDRO, or to a Trust of a Non-Qualified Stock Option shall not be treated as having caused a new grant. If an Award is so transferred, the Alternate Payee or Trust generally has the same rights as the Eligible Director under the terms of the Program; provided however, that (i) the Award shall be subject to the same terms and conditions, including the vesting terms, option termination provisions and exercise period, as if the Award were still held by the Eligible Director, and (ii) such Alternate Payee or Trust may not transfer an Award. In the event of the Company Stock Administrator’s receipt of a domestic relations order or other notice of adverse claim by an Alternate Payee of an Eligible Director of an Award, transfer of the proceeds of the exercise of such Award, whether in the form of cash, stock or other property, may be suspended. Such proceeds shall thereafter be transferred pursuant to the terms of a QDRO or other agreement between the Eligible Director and Alternate Payee. An Eligible Director’s ability to exercise an Award may be barred if the Company Stock Administrator receives a court order directing the Company Stock Administrator not to permit exercise.

5.6 Nature of Program. No Eligible Director, beneficiary or other person shall have any right, title or interest in any fund or in any specific asset of the Company or any Affiliate by reason of any award hereunder. There shall be no funding of any benefits which may become payable hereunder. Nothing contained in this Program (or in any document related thereto), nor the creation or adoption of this Program, nor any action taken pursuant to the provisions of this Program shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the Company or an Affiliate and any Eligible Director, beneficiary or other person. To the extent that an Eligible Director, beneficiary or other person acquires a right to receive payment with respect to an award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company or other

7

employing entity, as applicable. All amounts payable under this Program shall be paid from the general assets of the Company or employing entity, as applicable, and no special or separate fund or deposit shall be established and no segregation of assets shall be made to assure payment of such amounts. Nothing in this Program shall be deemed to give any person any right to participate in this Program except in accordance herewith.

5.7 Governing Law. This Program shall be construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law thereof.

5.8 Code Section 409A. To the extent that this Program constitutes a “non-qualified deferred compensation plan” within the meaning of with Code Section 409A and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Effective Date, this Program shall be interpreted and operated in accordance with Code Section 409A. Notwithstanding any provision of this Program to the contrary, in the event that following the grant of any Restricted Stock Units, the Board determines that any Award does or may violate any of the requirements of Code Section 409A, the Board may adopt such amendments to the Program and any affected Award or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Board determines are necessary or appropriate to (a) exempt the Program and any such Award from the application of Code Section 409A and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (b) comply with the requirements of Code Section 409A; provided, however, that this paragraph shall not create an obligation on the part of the Board to adopt any such amendment, policy or procedure or take any such other action.
