GRANT OF OPTION

2.1 Grant of Option. In consideration of Participant’s past and/or continued employment with or service to the Company or a Parent or Subsidiary and for other good and valuable consideration, effective as of the Grant Date set forth in the Grant Notice (the “Grant Date”), the Company irrevocably grants to Participant the Option to purchase any part or all of an aggregate of the number of shares of Stock set forth in the Grant Notice, upon the terms and conditions set forth in the Plan and this Agreement.

Notwithstanding the foregoing, if this Option is designated as an Incentive Stock Option and Participant owns (within the meaning of Section 424(d) of the Code) more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any “subsidiary corporation” of the Company or any “parent corporation” of the Company (each within the meaning of Section 424 of the Code), the price per share of the shares subject to the Option shall not be less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the Grant Date.

2.3 Consideration to the Company. In consideration of the grant of the Option by the Company, Participant agrees to render faithful and efficient services to the Company or any Parent or Subsidiary.

1

interfere with or restrict in any way the rights of the Company and its Parents and Subsidiaries, which rights are hereby expressly reserved, to discharge or terminate the services of Participant at any time for any reason whatsoever, with or without Cause, except to the extent expressly provided otherwise in a written agreement between the Company, a Parent or a Subsidiary and Participant.

3.3 Expiration of Option. The Option may not be exercised to any extent by anyone after the first to occur of the following events:

(a) The expiration of ten (10) years from the Grant Date;

(b) If this Option is designated as an Incentive Stock Option and Participant owned (within the meaning of Section 424(d) of the Code), at the time the Option was granted, more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any “subsidiary corporation” of the Company or any “parent corporation” of the Company (each within the meaning of Section 424 of the Code), the expiration of five (5) years from the Grant Date;

(e) In connection with a Change of Control, the date and time provided under Article 11 of the Plan.

Participant acknowledges that an Incentive Stock Option exercised more than three (3) months after Participant’s Termination of Employment, other than by reason of death or Disability, will be taxed as a Non-Qualified Stock Option.

Participant further acknowledges that the rule set forth in the preceding sentence shall be applied by taking the Option and other “incentive stock options” into account in the order in which they were granted, as determined under Section 422(d) of the Code and the Treasury Regulations thereunder.

ARTICLE IV

EXERCISE OF OPTION

4.1 Person Eligible to Exercise. Except as provided in Sections 5.2(b) and 5.2(c), during the lifetime of Participant, only Participant may exercise the Option or any portion thereof. After the death of Participant, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable under Section 3.3, be exercised by Participant’s personal representative or by any person empowered to do so under the deceased Participant’s will or under the then applicable laws of descent and distribution.

4.2 Partial Exercise. Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes unexercisable under Section 3.3.

4.3 Manner of Exercise. The Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary of the Company or the Secretary’s office of all of the following prior to the time when the Option or such portion thereof becomes unexercisable under Section 3.3:

(a) An Exercise Notice (“Exercise Notice”) in writing signed by Participant or any other person then entitled to exercise the Option or portion thereof, stating that the Option or portion thereof is thereby exercised, such notice complying with all applicable rules established by the Committee. Such Exercise Notice shall be substantially in the form attached as Exhibit C to the Grant Notice (or such other form as is prescribed by the Committee);

(b) The receipt by the Company of full payment for the shares with respect to which the Option or portion thereof is exercised, including payment of any applicable withholding tax, which may be in one or more of the forms of consideration permitted under Section 4.4;

3

(c) A bona fide written representation and agreement, in such form as is prescribed by the Committee, signed by Participant or the other person then entitled to exercise such Option or portion thereof, stating that the shares of Stock are being acquired for Participant’s own account, for investment and without any present intention of distributing or reselling said shares or any of them except as may be permitted under the Securities Act and then applicable rules and regulations thereunder and any other applicable law, and that Participant or other person then entitled to exercise such Option or portion thereof will indemnify the Company against and hold it free and harmless from any loss, damage, expense or liability resulting to the Company if any sale or distribution of the shares by such person is contrary to the representation and agreement referred to above. The Committee may take such additional actions it deems appropriate to ensure the observance and performance of such representation and agreement and to effect compliance with the Securities Act and any other federal or state securities laws or regulations and any other applicable law. Without limiting the generality of the foregoing, the Committee may require an opinion of counsel acceptable to it to the effect that any subsequent transfer of shares acquired on an Option exercise does not violate the Securities Act, and may issue stop-transfer orders covering such shares. Share certificates evidencing Stock issued on exercise of the Option shall bear an appropriate legend referring to the provisions of this subsection (c) and the agreements herein. The written representation and agreement referred to in the first sentence of this subsection (c) shall, however, not be required if the shares to be issued pursuant to such exercise have been registered under the Securities Act, and such registration is then effective in respect of such shares; and

(d) In the event the Option or portion thereof shall be exercised pursuant to Section 4.1 by any person or persons other than Participant, appropriate proof of the right of such person or persons to exercise the Option.

4.4 Method of Payment. Payment of the exercise price shall be by any of the following, or a combination thereof, at the election of the Participant:

(a) cash;

(b) check;

(c) with the consent of the Committee, delivery of a notice that the Participant has placed a market sell order with a broker with respect to shares of Stock then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the aggregate exercise price; provided, that payment of such proceeds is then made to the Company upon settlement of such sale;

(d) with the consent of the Committee, surrender of other shares of Stock which (A) in the case of shares of Stock acquired from the Company, have been owned by the Participant for more than six (6) months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the shares with respect to which the Option or portion thereof is being exercised;

4

(e) with the consent of the Committee, surrendered shares of Stock issuable upon the exercise of the Option having a Fair Market Value on the date of exercise equal to the aggregate exercise price of the shares with respect to which the Option or portion thereof is being exercised; or

(f) with the consent of the Committee, property of any kind which constitutes good and valuable consideration.

4.5 Conditions to Issuance of Stock Certificates. The shares of Stock deliverable upon the exercise of the Option, or any portion thereof, may be either previously authorized but unissued shares or issued shares which have then been reacquired by the Company. Such shares shall be fully paid and nonassessable. The Company shall not be required to issue or deliver any shares of Stock purchased upon the exercise of the Option or portion thereof prior to fulfillment of all of the following conditions:

(a) The admission of such shares to listing on all stock exchanges on which such Stock is then listed;

(b) The completion of any registration or other qualification of such shares under any state or federal law or under rulings or regulations of the Securities and Exchange Commission or of any other governmental regulatory body, which the Committee shall, in its reasonable discretion, deem necessary or advisable;

(c) The obtaining of any approval or other clearance from any state or federal governmental agency which the Committee shall, in its reasonable discretion, determine to be necessary or advisable;

(d) The receipt by the Company of full payment for such shares, including payment of any applicable withholding tax, which may be in one or more of the forms of consideration permitted under Section 4.4;

(e) The lapse of such reasonable period of time following the exercise of the Option as the Committee may from time to time establish for reasons of administrative convenience; and

(f) The adoption and execution of any agreement among the holders of the Company’s Stock, as may be amended from time to time, or any similar agreement as the Company may request.

4.6 Rights as Stockholder. The holder of the Option shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any shares purchasable upon the exercise of any part of the Option unless and until such shares shall have been issued by the Company to such holder (as evidenced by the appropriate entry on the books of the Company or

5

of a duly authorized transfer agent of the Company). No adjustment will be made for a dividend or other right for which the record date is prior to the date the shares are issued, except as provided in Article 11 of the Plan.

ARTICLE V

OTHER PROVISIONS

5.1 Administration. The Committee shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret, amend or revoke any such rules.

No member of the Committee shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan, this Agreement or the Option.

5.2 Option Not Transferable.

(a) Subject to Section 5.2(b), the Option may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution, unless and until the shares underlying the Option have been issued, and all restrictions applicable to such shares have lapsed.

(b) Notwithstanding any other provision in this Agreement, with the consent of the Committee and to the extent the Option is not intended to qualify as an Incentive Stock Option, the Option may be transferred to one or more Permitted Transferees, subject to the terms and conditions set forth in Section 10.3 of the Plan.

(c) Unless transferred to a Permitted Transferee in accordance with Section 5.2(b), during the lifetime of Participant, only Participant may exercise the Option or any portion thereof. Subject to such conditions and procedures as the Committee may require, a Permitted Transferee may exercise the Option or any portion thereof during Participant’s lifetime. After the death of Participant, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable under Section 3.3, be exercised by Participant’s personal representative or by any person empowered to do so under the deceased Participant’s will or under the then applicable laws of descent and distribution.
