The number of shares of Incentive Stock and Restricted Stock which (i) may be issued by the Corporation under this Plan pursuant to the exercise of Options granted hereunder, (ii) may be covered by SAR’s granted hereunder which have not expired unexercised, and (iii) may be issued by the Corporation under this Plan pursuant to the exercise of Rights granted hereunder, shall not exceed an aggregate of Sixty-Three Million Four Hundred Eighteen Thousand Seven Hundred Sixty-Four (63,418,764), which amount may be increased only by a resolution adopted by the Board of

-4-

Directors and approved by the stockholders of the Corporation in accordance with the Corporation Law within twelve (12) months after such adoption by the Board of Directors. Such shares of Incentive Stock and Restricted Stock may be issued out of the authorized and unissued or reacquired Common Stock of the Corporation. Any shares subject to an Option, SAR, Right or portion thereof which expires or is terminated unexercised (unless by virtue of the exercise of an Option, SAR or Right granted in tandem therewith) as to such shares may again be subject to an Option, SAR or Right under this Plan. To the extent there shall be any adjustment in the number of shares of Incentive Stock and/or Restricted Stock pursuant to the provisions of Section 9 hereof, the aforesaid aggregate number of shares which may be issued by the Corporation under this Plan shall be likewise adjusted.

A. As soon as practicable after the Board of Directors determines to award an Option, SAR or Right, the appropriate officer or officers of the Corporation shall give notice (written or oral) to such effect to each Eligible Person designated to be awarded an Option, SAR or Right, which notice shall be accompanied by a copy or copies of the Stock Option Agreement or Restricted Stock Agreement (as applicable) to be executed by such Eligible Person. The Board of Directors may delegate to the appropriate officer or officers of the Corporation the authority to prepare, execute and deliver any Stock Option Agreement or Restricted Stock Agreement evidencing any Option, SAR or Right granted under this Plan; provided, however, that any such Stock Option Agreement or Restricted Stock Agreement shall be consistent with the terms and conditions of this Plan.

B. Upon receipt of the notice specified in Section 5A hereof, an Eligible Person shall have an Option, SAR or Right (as the case may be). Such Eligible Person shall nonetheless become and be a Participant only after the due execution and delivery by such Eligible Person and the Corporation of a Stock Option Agreement or Restricted Stock Agreement (in such form and number as the officer or officers of the Corporation shall direct) by such date and time as shall be specified in such notice (unless waived by the Corporation).

C. For any Option intended to qualify as an ISO, in whole or in part, (i) the Eligible Person shall then be an employee of the Corporation or a Parent or Subsidiary, as provided in the Code, (ii) the term during which such Option shall be in effect shall not be greater than ten (10) years, except in the case of an Option granted to a Controlling Participant, in which case the term shall not be greater than five (5) years, (iii) the Exercise Price shall not be less than one hundred percent (100%) of the Fair Market Value on the date that such Option is granted, except in the case of an ISO granted to a Controlling Participant, in which case the Exercise Price shall not be less than one hundred ten percent (110%) of the Fair Market Value on the date that such Option is granted and (iv) such Option shall be exercisable only by the Participant during his or her lifetime and shall be nontransferable by the Participant unless the Stock Option Agreement permits such Option to be transferred by will or the laws of descent and distribution.

D. The purchase price for each share of Restricted Stock, as determined by the Board of Directors, need not be the Fair Market Value thereof, and may vary from one Participant to another. In addition, the terms and conditions on which shares of Restricted Stock may be purchased

-5-

may vary from one Participant to another. In computing the purchase price of a share of Restricted Stock, the Board of Directors may take into consideration, without limitation, the restrictions on transfer or other disposition imposed in the applicable Restricted Stock Agreement.

E. In the event that the Corporation or any Parent or Subsidiary assumes an option granted by another entity, which option is to be covered by this Plan and upon the exercise of which shares of Incentive Stock are to be issued, the terms and conditions of such option shall remain unchanged (except the exercise price and the number and nature of shares issuable upon exercise thereof, which shall be adjusted appropriately in accordance with the Code, and references to such other entity, which shall be deemed to refer to the Corporation). In the event that the Board of Directors elects to grant an Option, SAR or Right under this Plan to replace an option, SAR or right granted by another entity (rather than assume such option, SAR or Right), the holder of such option or SAR shall be eligible to receive such replacement Option, SAR or Right, which may be granted with a similarly-adjusted Exercise Price.

A. An Option or SAR of a Participant may be exercised during the period such Option or SAR is in effect and as set forth herein and in the Stock Option Agreement, and only if compliance with all applicable federal and state securities laws can be effected. An Option or SAR may be exercised only by (i) the Participant’s completion, execution and delivery to the Corporation of a notice of such Participant’s exercise of such Option and an “investment letter” (if required by the Corporation) as supplied by the Corporation and (ii) the payment to the Corporation of the aggregate Exercise Price, in accordance with Section 6C hereof and the Stock Option Agreement, for the shares of Incentive Stock to be purchased pursuant to such exercise (as shall be specified by such Participant in such notice). Except as otherwise specifically provided by a duly executed Stock Option Agreement or unless waived by the Board of Directors, an Option or any of the rights thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law (including, without limitation, the laws of bankruptcy, intestacy, descent and distribution and succession).

B. A Right of a Participant may be exercised during the period such Right is in effect and as set forth herein and in the Restricted Stock Agreement, and only if compliance with all applicable federal and state securities laws can be effected. A Right may be exercised only by (i) the Participant’s completion, execution and delivery to the Corporation of a notice of such Participant’s exercise of such Right (if such exercise is not simultaneous with the execution of the applicable Restricted Stock Agreement) and an “investment letter” (if required by the Corporation) as supplied by the Corporation and (ii) the payment to the Corporation of the aggregate Exercise Price, in accordance with Section 6C hereof and the Restricted Stock Agreement, for the shares of Restricted Stock to be purchased pursuant to such exercise (as shall be specified by such Participant in such notice). Except as otherwise specifically provided by a duly executed Restricted Stock Agreement or unless waived by the Board of Directors, a Right or any of the rights thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law (including, without limitation, the laws of bankruptcy, intestacy, descent and distribution and succession).

-6-

C. Payment by each Participant for the shares of Incentive Stock or Restricted Stock purchased hereunder upon the exercise of an Option or a Right shall be made (i) in cash, (ii) by good check or (iii) in accordance with the terms of the applicable Stock Option Agreement or Restricted Stock Agreement executed by such Participant.

D. The Board of Directors at any time or from time to time may offer to buy out for a payment in cash or Incentive Stock all or a portion of an outstanding Option held by a Participant, based on such terms and conditions as the Board of Directors shall establish and communicate to the Participant at the time that such offer is made. The Board of Directors may provide for the surrender of all or any portion of an Option in satisfaction of specified obligations of a Participant, including tax withholding obligations.

E. As a condition to the exercise of any Option or SAR (for non-cash consideration), the Corporation shall have the right to require that the Participant (or the recipient of any shares of Incentive Stock or noncash consideration) remit to the Corporation or any Parent or Subsidiary an amount calculated by the Corporation to be sufficient to satisfy applicable federal, state, foreign or local withholding tax requirements prior to the delivery of any stock certificate evidencing shares of Incentive Stock or other form of non-cash consideration; in lieu thereof, the Participant may satisfy applicable withholding tax requirements by electing to have the Corporation withhold from the Incentive Stock issuable upon exercise of an Option a number of whole shares having a Fair Market Value (determined on the date that the amount of tax to be withheld is to be fixed) at least equal to the aggregate amount required to be withheld. Whenever any payments are to be made in cash (upon the exercise of a SAR or otherwise), the Corporation shall be entitled, in its sole discretion, to deduct from such payment such amount calculated by the Corporation to be sufficient to satisfy applicable federal, state, foreign or local withholding tax requirements thereon.

All costs and expenses with respect to the adoption, implementation, interpretation and administration of this Plan shall be borne by the Corporation; provided, however, that, except as otherwise specifically provided in this Plan or the applicable Stock Option Agreement or Restricted Stock Agreement between the Corporation and a Participant, the Corporation shall not be obligated to pay any costs or expenses (including legal fees) incurred by any Participant in connection with any Stock Option Agreement, Restricted Stock Agreement, this Plan or any Option, SAR, Right, Restricted Stock or Incentive Stock held by any Participant.

Nothing in this Plan shall be deemed to give any director, officer or employee of, or advisor or consultant to, the Corporation or any Parent or Subsidiary, or such person’s legal representatives or assigns, or any other person or entity claiming under or through such person, any contract or other right to participate in the benefits of this Plan. Nothing in this Plan shall be construed as constituting a commitment, guarantee, agreement or understanding of any kind or nature that the Corporation or any Parent or Subsidiary shall continue to employ, retain or engage any person (whether or not a Participant). This Plan shall not affect in any way the right of the Corporation and any Parent or Subsidiary to terminate the employment or engagement of any person (whether or not a Participant)

-7-

at any time and for any reason whatsoever and to remove any person (whether or not a Participant) from any position as a director or officer. No change of a Participant’s duties as an employee of the Corporation or any Parent or Subsidiary shall result in a modification of the terms of any rights of such Participant under this Plan or any Stock Option Agreement or Restricted Stock Agreement executed by such Participant.

Subject to any required action by the stockholders of the Corporation and the provisions of the Corporation Law, the number of shares of:

(i) Incentive Stock represented by the unexercised portion of an Option or SAR;

(ii) Restricted Stock represented by the unexercised portion of a Right; and

(iii) Incentive Stock and Restricted Stock which have been authorized or reserved for issuance hereunder (whether such shares are unissued, reacquired or subject to an Option, SAR or Right that expired, was cancelled, surrendered or terminated unexercised as to such shares),

as well as the Exercise Price under the unexercised portion of an Option or SAR and the purchase price of a share of Restricted Stock represented by the unexercised portion of a Right, shall be proportionately adjusted for (a) each division, combination or reclassification of any of the shares of Common Stock of the Corporation and (b) each dividend declared by the Board of Directors and payable in shares of Common Stock of the Corporation.

Except as otherwise provided herein or as required by law, this Plan may be amended or terminated in whole or in part by the Board of Directors (in its sole discretion), but no such action shall adversely affect or alter any right or obligation with respect to any Option, SAR, Right, Stock Option Agreement or Restricted Stock Agreement then in effect, except to the extent that any such action shall be required or desirable (in the opinion of the Corporation or its counsel) so that any Option intended to qualify as an ISO complies with the Code or any rule or regulation promulgated or proposed thereunder.

The terms and provisions of this Plan shall be binding upon, and shall inure to the benefit of, each Participant and such Participant’s executors and administrators, estate, heirs and personal and legal representatives.

The headings and other captions contained in this Plan are for convenience of reference only and shall not be used in interpreting, construing or enforcing any of the provisions of this Plan.

Notwithstanding any provision of this Plan or any provision of any Stock Option Agreement evidencing an Option that is intended, in whole or in part, to qualify as an ISO, this Plan and each such Stock Option Agreement are intended to comply with all requirements for qualification under the Code and with any rule or regulation promulgated or proposed thereunder, and shall be interpreted and construed in a manner which is consistent with this Plan and each such Stock Option Agreement being so qualified.

This Plan shall be governed by, and construed in accordance with, the substantive laws of the Corporation’s jurisdiction of incorporation (other than provisions thereof relating to conflicts of law and choice of law).
