Employees, Directors and Consultants shall be eligible to receive Options, Restricted Stock, Restricted Stock Units, SARs, Deferred Stock and Performance Shares under the Plan.

Options granted under this Plan shall be subject to such terms and conditions not inconsistent with the Plan as the Administrator shall determine, including the following:

(a) Option Agreement. Any grant of an Option shall be confirmed by the execution of an Option Agreement. To the extent this Plan receives the requisite stockholder approval, Options can be designated as incentive stock options under Section 422 of the Code in the Option Agreement. If Options are not designated as incentive stock options, or do not meet the qualifications of Section 422 of the Code, such Options shall be nonqualified stock options.

The Administrator may permit the exercise of an Option to the extent unvested. If so permitted, then upon the exercise of an Option or portion of an Option that has not vested, the Shares received pursuant to such exercise to the extent attributable to the unvested portion of the Option shall be Restricted Stock subject to Paragraph 9 hereof, and having a vesting schedule the same as the vesting schedule of the Option or portion of the Option in respect of which the Shares were received.

Unless otherwise determined by the Administrator, such price shall be paid in full at the time that an Option is exercised. If the Participant, elects to pay all or a part of the exercise price in Shares, such Participant may make such payment by delivering to the Company a number of Shares already owned by the Participant, either directly or by attestation, which are equal in value to the purchase or exercise price. All Shares so delivered shall be valued for this purpose at their Fair Market Value on the day on which such Shares are delivered.

(5) If a Participant ceases to be an Employee, a Director or a Consultant for a reason other than those specified above, such Employee or Consultant (with respect to an Option granted to him or her in the capacity of an Employee or Consultant) or Director (with respect to an Option granted to him or her in the capacity of a Director) shall have ninety days from the date of such cessation to exercise any such Option with respect to such of the Shares subject thereto as to which such Participant then has a present right to exercise; provided, however, that no Option shall be exercisable subsequent to ten years from its date of grant.

(i) Distribution of Shares with Respect to Restricted Stock Units. Each Participant who holds Restricted Stock Units shall be entitled to receive from the Company one Share for each Restricted Stock Unit, as adjusted from time to time in the manner set forth in Paragraph 15, below. However, the Company, as determined in the sole discretion of the Administrator at the time of grant only, shall be entitled to settle its obligation to deliver Shares by instead making a payment of cash substantially equal to the fair market value of the Shares it would otherwise be obligated to deliver, or by the issuance of a combination of Shares and cash, in the proportions determined by the Administrator, substantially equal to the fair market value of the Shares the Company would otherwise be obligated to deliver. The fair market value of a Share for this purpose will mean the Fair Market Value on the business day immediately preceding the date of the cash payment. Except as otherwise determined by the Administrator at the time of the grant, Restricted Stock Units shall vest and Shares shall be distributed to the Participant in respect thereof as of the vesting date; provided, however, if any grant of Restricted Stock Units to a Participant who is subject to U.S. federal income tax is nonqualified deferred compensation for purposes of Section 409A of the Code, cash or Shares shall only be distributed in a manner such that Section 409A of the Code will not cause the Participant to become subject to penalties and/or interest thereunder; and provided, further, that no cash or Shares shall be distributed in respect of Restricted Stock Units prior to the date on which such Restricted Stock Unit vest.

On the first day of each calendar year, each Participant who holds Restricted Stock Units and who remains an Employee, Director or Consultant (as applicable) on such date, shall be granted, automatically and specifically without further action of the Board of Directors or the Administrator, a number of additional Restricted Stock Units equal to (i) the aggregate amount of dividends (or distributions) which would have been received by a shareholder holding a number of Shares equal to the number of Restricted Stock Units held by such Participant on the record date of any such dividend or distribution on such date, divided by (ii) the Average Trading Price for the preceding calendar year. A Participant who ceases to be an Employee or a Director or a Consultant (as applicable) shall be granted, automatically and specifically without further action of the Board of Directors, on the day following the date of such cessation, a number of additional Restricted Stock Units equal to (1) the total amount of dividends which would have been received by the Participant during the portion of the year ending when such cessation occurs if the Restricted Stock Units held by the Participant on the record date of any such dividend had been outstanding Shares on such date, (2) divided by the Average Trading Price for the period from January 1 of such year through the date of such cessation. In the event of any distribution other than cash, the foregoing shall be applied based on the fair market value of the property distributed. Additional Restricted Stock Units granted under this Subparagraph 9(j) shall vest and be distributed on the same terms and in the same proportions as the Restricted Stock Units to which the dividends and distributions relate.

13

(3) Except as otherwise determined by the Administrator, upon the occurrence of a Change in Control while a Participant is an Employee, a Director or a Consultant, all outstanding SARs held by such Participant shall become immediately exercisable.

(4) Notwithstanding the foregoing, no SAR shall be exercisable subsequent to ten years from its date of grant. Every SAR which has not been exercised within ten years of its date of grant shall lapse upon the expiration of such ten-year period unless it shall have lapsed at an earlier date.

(d) Rights on Exercise. An SAR shall entitle the Participant to receive from the Company upon exercise a number of Shares determined in accordance with the following formula. First, determine (1) the excess of the Fair Market Value of one Share on the date of exercise over (2) the Grant Value for such SAR as set forth in the applicable SAR Agreement. Second, multiply such excess by (3) the number of SARs exercised. Third, divide the product by (4) the Fair Market Value of one Share on the date of exercise to determine the number of Shares to which the Participant is entitled from the SAR exercise

(e) Cessation of Status. Except as determined otherwise by the Administrator:

(1) Upon the Retirement of an Employee or a Director, such Employee (with respect to an SAR granted to him or her in the capacity of an Employee) or Director (with respect to an SAR granted to him or her in the capacity of a Director) shall have one year

14

from the date of such Retirement to exercise any SAR granted hereunder to the extent that as of such Retirement such Participant was vested in such SAR; provided, however, that no SAR shall be exercisable subsequent to ten years from its date of grant.

(2) Any Participant who ceases to be an Employee, a Director or a Consultant due to Disability shall have one year from the date of such cessation to exercise any SAR granted hereunder; provided, however, that no SAR shall be exercisable subsequent to ten years from its date of grant.

(3) In the event of the death of a Participant while an Employee, a Director, or a Consultant, as the case may be, any SAR granted to such Participant shall be exercisable:

(A) for one year after the Participant’s death, but in no event subsequent to ten years from its date of grant; and

(B) only (i) by the deceased Participant’s designated beneficiary (such designation to be made in writing at such time and in such manner as the Administrator shall approve or prescribe), or, if the deceased Participant dies without a surviving designated beneficiary, (ii) by the personal representative, administrator, or other representative of the estate of the deceased Participant, or by the person or persons to whom the deceased Participant’s rights under the SAR shall pass by will or the laws of descent and distribution.

(4) A Participant who holds (including following cessation of employment or service) an SAR who has designated a beneficiary for purposes of Subparagraph 10(e)(3)(B)(i) hereof may change such designation at any time, by written notice given to the Secretary of the Company, subject to such conditions and requirements as the Administrator may prescribe in accordance with applicable law.

(5) If a Participant ceases to be an Employee, a Director or a Consultant for a reason other than those specified above, such Employee or Consultant (with respect to an SAR granted to him or her in the capacity of an Employee or Consultant) or Director (with respect to an SAR granted to him or her in the capacity of a Director) shall have ninety days from the date of such cessation to exercise any such SAR to which such Participant then has a present right to exercise; provided, however, that no SAR shall be exercisable subsequent to ten years from its date of grant. Notwithstanding the foregoing, if a person ceases to be an Employee or a Consultant because of a termination of employment or service for Cause, to the extent an SAR is not effectively exercised prior to such cessation, it shall lapse immediately upon such cessation.

(f) The Administrator in its sole discretion may increase the periods permitted for exercise of an SAR if a Participant ceases to be an Employee, a Director or a Consultant as provided in Subparagraphs 10(e)(1), (2), (3) and (5) hereof if allowable under applicable law; provided, however, in no event shall an SAR be exercisable subsequent to ten years from its date of grant.

15

(g) Transferability. Except as otherwise provided in this Paragraph 10(g) or determined by the Administration, an SAR shall not be transferable or subjected to execution, attachment or similar process, and during the lifetime of the Participant shall be exercisable only by the Participant. A Participant shall have the right to transfer the SARs upon such Participant’s death, either to the deceased Participant’s designated beneficiary (such designation to be made in writing at such time and in such manner as the Administrator shall approve or prescribe), or, if the deceased Participant dies without a surviving designated beneficiary, by the terms of such Participant’s will or under the laws of descent and distribution, subject to any limitations set forth in the Plan or otherwise determined by the Administrator, and all such distributees shall be subject to all terms and conditions of the Plan to the same extent as would the Participant.

(h) Nature of SARs. No Participant shall have any interest in any fund or in any specific asset or assets of the Company by reason of any SARs granted hereunder, or any right to exercise any of the rights or privileges of a stockholder with respect to any SARs until Shares are issued in connection with any exercise.

Deferred Stock granted under this Plan shall be subject to such terms and conditions not inconsistent with the Plan as the Administrator shall determine, including the following:

(a) Grants. The terms of any grant of Deferred Stock shall be confirmed by the execution of a Deferred Stock Agreement.

(b) Distributions of Shares. Each Participant who holds Deferred Stock shall be entitled to receive from the Company one Share for each share of Deferred Stock, as adjusted from time to time in the manner set forth in Paragraph 15 hereof. However, the Company, as determined in the sole discretion of the Administrator at the time of grant only, shall be entitled to settle its obligation to deliver Shares by instead making a payment of cash substantially equal to the fair market value of the Shares it would otherwise be obligated to deliver, or by the issuance of a combination of Shares and cash, in the proportions determined by the Administrator, substantially equal to the fair market value of the Shares the Company would otherwise be obligated to deliver. The fair market value of a Share for this purpose will mean the Fair Market Value on the business day immediately preceding the date of the cash payment. Deferred Stock shall vest and Shares shall be distributed to the Participant in respect thereof at such time or times as determined in the Deferred Stock Agreement; provided, however, that, with respect to Deferred Stock that is treated as nonqualified deferred compensation under Section 409A of the Code, Shares shall only be distributed in accordance with the rules of Section 409A and any guidance issued thereunder (including any delay in distribution required if a Participant is a specified employee); and provided, further, that no Shares shall be distributed in respect of Deferred Stock prior to the date on which such Deferred Stock vests.

16

(c) Cessation of Status. Except as otherwise determined by the Administrator:

(1) If a Participant ceases to be an Employee, a Director or a Consultant for any reason, then except as provided in Subparagraphs 11(c)(2) and 11(d) hereof, such Employee or Consultant (with respect to Deferred Stock granted to him or her in the capacity of an Employee or a Consultant) or such Director (with respect to Deferred Stock granted to him or her in the capacity of a Director) shall forfeit all Deferred Stock held by such Participant on the date of termination that has not vested.

(2) Upon the Retirement of an Employee or a Director, all Deferred Stock then held by the Employee (which was granted to him or her in the capacity of an Employee), or all Deferred Stock then held by the Director (which was granted to him or her in the capacity of a Director), as the case may be, or upon the death or Disability of an Employee, Director or Consultant, all Deferred Stock then held by such Participant shall immediately vest.

(d) Vesting on Change in Control. Except as determined by the Administrator notwithstanding anything to the contrary herein contained, upon the occurrence of a Change in Control while a Participant is employed by the Company or a Subsidiary or is a Director or Consultant, all unvested Deferred Stock then held by such Participant shall immediately vest.

(e) Transferability. Deferred Stock may not be sold, assigned, conveyed, donated, pledged, transferred or otherwise disposed of or encumbered or subjected to execution, attachment, or similar process; provided, however, Shares distributed in respect of such Deferred Stock may be transferred in accordance with applicable securities laws. A Participant shall have the right to transfer Deferred Stock upon such Participant’s death, either to the deceased Participant’s designated beneficiary (such designation to be made in writing at such time and in such manner as the Administrator shall prescribe or approve), or, if the deceased Participant dies without a surviving designated beneficiary, by the terms of such Participant’s will or under the laws of descent and distribution, subject to any limitations set forth in the Plan or otherwise determined by the Administrator, and all such distributees shall be subject to all terms and conditions of the Plan to the same extent as would the Participant.

(f) No Rights as a Stockholder. No Participant shall have any interest in any fund or in any specific asset or assets of the Company by reason of any Deferred Stock granted hereunder, or any right to exercise any of the rights or privileges of a stockholder with respect to any Deferred Stock until Shares are distributed to the Participant.

(g) Dividends and Distributions. On the first day of each calendar year, each Participant who holds Deferred Stock and who remains an Employee, Director or Consultant on such date, shall be granted, automatically and specifically without further action of the Board of Directors or the Administrator, a number of shares of Deferred Stock equal to (1) the aggregate amount of dividends (or other distributions) which would have been received by the Participant during the immediately preceding year if the Deferred Stock held by the Participant (whether or not vested) on the record date of any such dividend or distribution had been outstanding Shares on such date, (2) divided by the Average Trading Price for the preceding calendar year. A Participant who ceases to be an Employee or a Director or a Consultant (as applicable) shall be granted, automatically and specifically without further action of the Board of Directors, on the day

17

following the date of such cessation, a number of shares of Deferred Stock equal to (1) the total amount of dividends which would have been received by the Participant during the portion of the year ending when such cessation occurs if the Deferred Stock held by the Participant (whether or not vested) on the record date of any such dividend had been outstanding Shares on such date, (2) divided by the Average Trading Price for the period from January 1 of such year through the date of such cessation. In the event of any distribution other than cash, the foregoing shall be applied based on the fair market value of the property distributed. Additional shares of Deferred Stock granted under this Subparagraph 11(g) shall be settled and Shares distributed in respect of such Deferred Stock at the same time as the Deferred Stock to which the dividends and distributions relate.

Performance Shares granted under this Plan shall be subject to such terms and conditions not inconsistent with the Plan as the Administrator shall determine, including the following:

(a) Nature of Performance Shares. The grant of any Performance Shares entitles the Participant to be granted Shares upon the attainment of performance goals specified in the Performance Shares Agreement. The Administrator in its sole discretion shall determine the performance goals (at target or other levels of performance) applicable to each Award of Performance Shares, the periods during which performance is to be measured, and all other limitations and conditions applicable to the awarded Performance Shares. Shares underlying any Award of Performance Shares shall be adjusted from time to time in the manner set forth in Paragraph 15 hereof.

(b) Rights as a Stockholder. A Participant receiving an Award of Performance Shares shall have the rights of a stockholder only as to Shares issued under the Plan upon the attainment of specified performance goals and not with respect to Shares subject to the Award but not issued to the Participant. A Participant shall be entitled to receive Shares only upon attainment of specified performance goals within the period specified in the Performance Shares Agreement, as certified by the Administrator.

(c) Cessation of Status. Except as determined otherwise by the Administrator, if a Participant ceases to be an Employee, a Director or a Consultant for any reason, then such Employee or Consultant (with respect to Performance Shares granted to him or her in the capacity of an Employee or a Consultant) or such Director (with respect to Performance Shares granted to him or her in the capacity of a Director) shall forfeit all Performance Shares held by such Participant on the date of termination that has not vested.

(d) Vesting on Change in Control. Except as determined otherwise by the Administrator, notwithstanding anything to the contrary herein contained, upon the occurrence of a Change in Control while a Participant is an Employee, a Director or a Consultant, all unearned and unvested Performance Shares then held by such Participant shall immediately become earned and shall vest as if the target level of performance established for each Award of Performance Shares had been achieved.

18

(e) Transferability. Performance Shares may not be sold, assigned, conveyed, donated, pledged, transferred or otherwise disposed of or encumbered or subjected to execution, attachment, or similar process; provided, however, that Shares distributed in respect of such Performance Shares may be transferred in accordance with applicable securities laws.

Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in other countries in which the Company and its Subsidiaries operate or have Employees, the Administrator shall have the power and authority in its sole discretion to: (a) determine which Subsidiaries shall be covered by the Plan; (b) determine which individuals outside the United States are eligible to participate in the Plan; (c) modify the terms and conditions of any Award granted to individuals outside the United States to comply with applicable foreign laws; (d) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however, that no such subplans and/or modifications shall increase the share limitations contained in Subparagraph 4(a) hereof; and (e) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals.

Each Option Agreement, Restricted Stock Agreement, Restricted Stock Units Agreement, SAR Agreement, Deferred Stock Agreement or Performance Shares Agreement shall contain such representations, warranties and other terms and conditions as shall be necessary in the opinion of counsel to the Company to comply with all applicable federal and state securities laws. The Company shall have the right to delay the issue or delivery of any Shares under the Plan until (a) the completion of such registration or qualification of such Shares under any federal or state law, ruling or regulation as the Company shall determine to be necessary or advisable, and (b) receipt from the Participant of such documents and information as the Administrator may deem necessary or appropriate in connection with such registration or qualification.

(a) Share Adjustments. In the event of any stock dividend, stock split, reverse stock split, recapitalization, merger, consolidation, combination or exchange of shares, or the like, as a result of which shares of any class shall be issued in respect of the outstanding Shares, or the Shares shall be changed into the same or a different number of the same or another class of stock, or into securities of another person, any distribution of cash or other property to the stockholders (other than a regular cash dividend), the total number of Shares authorized to be offered in accordance with Paragraph 4 hereof and any other limitations contained in Paragraph 4 hereof, the number of Shares subject to each outstanding Option, the number of Shares of

19

Restricted Stock or Restricted Stock Units then held by each Participant, the number of shares to which each then outstanding SAR or Award of Deferred Stock or Performance Shares relates, the exercise price applicable to each outstanding Option and the Grant Value of each outstanding SAR shall be adjusted in such equitable and proportionate manner as determined by the Administrator. No fractional Share shall be issued under the Plan resulting from any such adjustment but the Administrator in its sole discretion may make a cash payment in lieu of a fractional Share.

(b) Acquisitions. In the event of a merger or consolidation of the Company with another corporation or entity, or a sale or disposition by the Company of all or substantially all of its assets, the Administrator shall have authority in its sole discretion to provide for (1) waiver in whole or in part of any remaining restrictions or vesting requirements in connection with any Award granted hereunder, (2) the conversion of outstanding Options, Restricted Stock, Restricted Stock Units, SARs, Deferred Stock or Performance Shares into cash and/or (3) the conversion of Awards into the right to receive securities of another person upon such terms and conditions as are determined by the Administrator in its sole discretion.

(c) Binding Effect. Any adjustment, waiver, conversion or other action taken by the Administrator under this Paragraph 15 shall be conclusive and binding on all Participants and the Company and their respective successors and assigns.

The Company shall be entitled to pay and withhold from any amounts payable by the Company to a Participant the amount of any tax which it believes is required to be withheld under applicable law in connection with any Award, and the Company may defer making delivery of Shares until arrangements satisfactory to it have been made with respect to any such withholding obligations. If a Participant is permitted by the Administrator to do so, the Participant may, at his or her election, satisfy his or her obligation for payment of required withholding taxes by having the Company retain a number of Shares having an aggregate Fair Market Value on the date the Shares are withheld equal to the amount of the required withholding tax. If the Company will not accept Shares for payment of withholding taxes, the Participant must transfer cash to the Company equal to the withholding obligation. The tax withheld will not exceed the minimum required by law.

The Plan, as approved by the Board of Directors and the stockholders of the Company, shall become effective as of the date of such stockholder approval, and any amendment and/or restatement of the Plan shall become effective as of the date of approval by the Board of Directors, except that, if any amendment or restatement is subject to stockholder approval, the date of stockholder approval instead shall be the effective date.

20

Unless the Plan shall theretofore have been terminated as hereinafter provided, no Award shall be granted after the tenth anniversary of the date this Plan is approved by the Board of Directors. The Board of Directors may terminate the Plan or make such modifications or amendments thereof as it shall deem advisable, including, but not limited to, such modifications or amendments as it shall deem advisable in order to conform to any law or regulation applicable thereto; provided, however, that the Board of Directors may not, without further approval of the holders of a majority of the Shares voted at any meeting of stockholders at which a quorum is present and voting, adopt any amendment to the Plan for which stockholder approval is required under tax, securities or any other applicable law. No termination, modification or amendment of the Plan may, without the consent of the Participant, adversely affect the rights of such Participant under an outstanding Award then held by the Participant.

Except as otherwise provided in this Plan, the Administrator may amend an outstanding Award or any Option Agreement, Restricted Stock Agreement, Restricted Stock Units Agreement, SAR Agreement, Deferred Stock Agreement or Performance Shares Agreement; provided, however, that the Participant’s consent to such action shall be required unless the Administrator determines that the action, taking into account any related action, would not adversely affect the Participant. The Administrator may also modify or amend the terms of any Award granted under the Plan for the purpose of complying with, or taking advantage of, income or other tax or legal requirements or practices of foreign countries which are applicable to Participants.

Notwithstanding the above to the contrary, the Board of Directors or the Administrator may amend the Plan or any Award Agreement at any time, without the consent of any Participant, in order to cause the Plan or such Award Agreement to meet the requirements of Section 409A of the Code and any guidance promulgated thereunder in order to avoid causing any Participant to become subject to interest and/or penalties that would otherwise by imposed under Section 409A of the Code. In the event this Plan is terminated, any amounts allocated to a Participant hereunder that are subject to Section 409A of the Code shall be distributed to the Participant only in a manner permitted under Section 409A of the Code and any guidance promulgated thereunder.

Payments and other benefits received by an Employee under an Award granted pursuant to the Plan shall not be deemed a part of such Employee’s regular, recurring compensation for purposes of the termination, indemnity or severance pay law of any country and shall not be included in, or have any effect on, the determination of benefits under any other employee benefit plan, contract or similar arrangement provided by the Company or any Subsidiary unless expressly so provided by such other plan, contract or arrangement, unless required by law, or unless the Administrator expressly determines otherwise.

21

The Plan shall not confer upon any person any right to continue employment or service with the Company or a Subsidiary, nor shall it interfere in any way with the right of the Company or such Subsidiary to terminate any person’s employment or service at any time.

In the event any provision of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and this Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware, applied without regard to the laws of any other jurisdiction that otherwise would govern under conflict of law principles.
