GRANT OF OPTION

2.2 Purchase Price.

ARTICLE III

PERIOD OF EXERCISABILITY

3.1 Commencement of Exercisability.

(a) Subject to Sections 3.3 and 5.11, the Option shall become exercisable in such amounts and at such times as are set forth on the Grant Notice.

(b) No portion of the Option which has not become exercisable at Termination of Employment shall thereafter become exercisable, except as may be otherwise provided by the Committee.

3.2 Duration of Exercisability. The installments provided for in Section 3.1(a) and the Grant Notice are cumulative. Each such installment which becomes exercisable pursuant to Section 3.1 shall remain exercisable until it becomes unexercisable under Section 3.3.

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 seven (7) years from the Date of Grant; or

5.

(b) If this Option is designated as an Incentive Stock Option and the Optionee 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 or parent corporation thereof (within the meaning of Section 422 of the Code), the expiration of five (5) years from the date the Option was granted; or

(c) The expiration of three (3) months following the date of the Optionee’s Termination of Employment, unless such Termination of Employment occurs by reason of the Optionee’s discharge for Cause, or by reason of the Optionee’s death, Retirement or disability (within the meaning of Section 22(e)(3) of the Code); or

The Optionee further acknowledges that the rule set forth in the preceding sentence shall be applied by taking options into account in the order in which they were granted. For purposes of these rules, the Fair Market Value of stock shall be determined as of the time the option with respect to such stock is granted.

ARTICLE IV

EXERCISE OF OPTION

4.1 Person Eligible to Exercise. Subject to Section 5.2, during the lifetime of the Optionee, only the Optionee may exercise the Option or any portion thereof. After the death of the Optionee, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable under Section 3.3, be exercised by the Optionee’s personal representative or by any person empowered to do so under the Optionee’s will or under the then applicable laws of descent and distribution.

6.

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; provided, however, that each partial exercise shall be for not less than ten (10) shares and shall be for whole shares only.

4.3 Manner of Exercise. Except as otherwise provided herein, the Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary 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 in writing signed by the Optionee or the 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 notice shall be substantially in the form attached as Attachment III to the Grant Notice (or such other form as is prescribed by the Committee); and

(b) (i) Full payment (in cash or by check) for the shares with respect to which the Option or portion thereof is exercised, to the extent permitted under applicable laws; or

(ii) With the consent of the Committee, such payment may be made, in whole or in part, through the delivery of shares of Common Stock which have been owned by the Optionee for at least six months, duly endorsed for transfer to the Company with a Fair Market Value on the date of delivery equal to the aggregate exercise price of the Option or exercised portion thereof; or

(iii) To the extent permitted under applicable laws, through the delivery of a notice that the Optionee has placed a market sell order with a broker with respect to shares of Common 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 Option exercise price, provided, that payment of such proceeds is then made to the Company upon settlement of such sale; or

(iv) With the consent of the Committee, any combination of the consideration provided in the foregoing subparagraphs (i), (ii) and (iii); and

(c) A bona fide written representation and agreement, in such form as is prescribed by the Committee, signed by the Optionee or other person then entitled to exercise such Option or portion thereof, stating that the shares of Common Stock are being acquired for the Optionee’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 that the Optionee 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,

7.

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, in its absolute discretion, take whatever 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. 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 Common 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) Full payment to the Company (or other employer corporation) of all amounts which, under federal, state or local tax law, it is required to withhold upon exercise of the Option. With the consent of the Committee, (i) shares of Common Stock owned by the Optionee for at least six months duly endorsed for transfer or (ii) shares of Common Stock issuable to the Optionee upon exercise of the Option, having a Fair Market Value at the date of Option exercise equal to the statutory minimum sums required to be withheld, may be used to make all or part of such payment; and

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

(f) Notwithstanding anything to the contrary herein, if upon expiration of the Option as set forth in Section 3.3 above, (i) any portion of the Option that is then exercisable remains unexercised and (ii) as of such expiration date the Fair Market Value is greater than the exercise price of the Option by at least one percent (1%), then the unexercised Option or portion thereof shall be automatically exercised as of the close of business on such expiration date. In the event of such automatic exercise, payment for the Option shall be made through the surrender of shares of Common Stock then issuable upon exercise of the Option having a Fair Market Value on the date of Option exercise equal to the aggregate exercise price of the Option or exercised portion thereof, in accordance with Section 6.2 of the Plan, and any applicable tax withholding shall be satisfied by the Company withholding shares of Common Stock otherwise issuable under such Option (or allowing the return of shares of Common Stock) having a Fair Market Value equal to the statutory minimum sums required to be withheld, in accordance with Section 12.6 of the Plan.

4.4 Conditions to Issuance of Stock Certificates. The shares of Common 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

8.

reacquired by the Company. Such shares shall be fully paid and nonassessable. The Company shall not be required to issue or deliver any certificate or certificates for shares of Common 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 Common Stock is then listed; and

(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 absolute discretion, deem necessary or advisable; and

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

(d) The receipt by the Company of full payment for such shares, including payment of all amounts which, under federal, state or local tax law, the Company (or other employer corporation) is required to withhold upon exercise of the Option; and

(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.

4.5 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 certificates representing such shares shall have been issued by the Company to such holder.

4.6 Change in Control. In the event of a Change in Control, the treatment of awards as set forth in Section 12.4 of the Plan shall not apply to the Option, and instead, the following provisions shall apply:

(a) In the event of a Change in Control, the surviving entity or acquiring entity (or the surviving or acquiring entity’s parent company) shall assume the Option or shall substitute similar stock options or rights for the Option; provided, however, and not withstanding anything to the contrary herein, if within the period beginning upon the consummation of the Change in Control and ending eighteen (18) months after a Change in Control, Optionee incurs a Termination of Employment by the Company for reasons other than for Cause, or by Optionee for Good Reason, any and all unvested Options granted hereunder will automatically accelerate and become immediately exercisable.

(b) Notwithstanding the foregoing, to the extent the surviving entity (or acquiring entity or parent company, as the case may be) refuses to assume the Option or to substitute an equivalent stock option or right (as determined by the Administrator in its

9.

sole discretion), immediately prior to such Change in Control the Option shall become fully vested and exercisable for all of the shares of Common Stock at the time subject to the Option and may be exercised for any or all of those shares as fully-vested shares of Common Stock.

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. All actions taken and all interpretations and determinations made by the Committee in good faith shall be final and binding upon the Optionee, the Company and all other interested persons. 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) The Option may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution or, subject to the consent of the Committee, pursuant to a “DRO” (as defined in the Plan), unless and until the Option has been exercised, or the shares underlying such Option have been issued, and all restrictions applicable to such shares have lapsed. Neither the Option nor any interest or right therein shall be liable for the debts, contracts or engagements of the Optionee or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect, except to the extent that such disposition is permitted by the preceding sentence.

(b) During the lifetime of the Optionee, only the Optionee may exercise the Option (or any portion thereof), unless it has been disposed of with the consent of the Committee pursuant to a DRO. After the death of the Optionee, any exercisable portion of an Option may, prior to the time when such portion becomes unexercisable under the Plan or the Option Agreement, be exercised by the Optionee’s personal representative or by any person empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution.

(c) Notwithstanding the foregoing provisions of this Section 5.2, if designated as a Non-Qualified Stock Option, the Option may be transferred by the Optionee, in writing and with prior written notice to the Committee, to any one or more Permitted

10.

Transferees (as defined below), subject to the following terms and conditions: (i) the Option, as transferred to a Permitted Transferee, shall not be assignable or transferable by the Permitted Transferee other than by will or the laws of descent and distribution; (ii) the Option, as transferred to a Permitted Transferee, shall continue to be subject to all the terms and conditions of the Option as applicable to the Optionee (other than the ability to further transfer the Option); and (iii) the Optionee and the Permitted Transferee shall execute any and all documents requested by the Committee, including, without limitation documents to (A) confirm the status of the transferee as a Permitted Transferee, (B) satisfy any requirements for an exemption for the transfer under applicable federal and state securities laws and (C) evidence the transfer. For purposes of this subsection (c), “Permitted Transferee” shall mean, with respect to the Optionee, any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the Optionee’s household (other than a tenant or employee), a trust in which these persons (or the Optionee) control the management of assets, and any other entity in which these persons (or the Optionee) own more than fifty percent (50%) of the voting interests, or any other transferee specifically approved by the Committee after taking into account any state or federal tax or securities laws applicable to transferable Non-Qualified Stock Options.

5.3 Lock-Up Period. The Optionee hereby agrees that, if so requested by the Company or any representative of the underwriters (the “Managing Underwriter”) in connection with any registration of the offering of any securities of the Company under the Securities Act, the Optionee shall not sell or otherwise transfer any shares of Common Stock or other securities of the Company during such period as may be requested in writing by the Managing Underwriter and agreed to in writing by the Company (which period shall not be longer than 180 days) (the “Market Standoff Period”) following the effective date of a registration statement of the Company filed under the Securities Act.

(b) The Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(c) The Company shall not be required: (i) to transfer on its books any shares of Common Stock that have been sold or otherwise transferred in violation of any of the provisions of this Agreement, or (ii) to treat as owner of such shares of Common Stock or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such shares shall have been so transferred.

11.

5.5 Shares to Be Reserved. The Company shall at all times during the term of the Option reserve and keep available such number of shares of Common Stock as will be sufficient to satisfy the requirements of this Agreement.

5.6 Notices. Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of the Secretary, and any notice to be given to the Optionee shall be addressed to the Optionee at the address given beneath the Optionee’s signature hereto. By a notice given pursuant to this Section 5.6, either party may hereafter designate a different address for notices to be given to that party. Any notice which is required to be given to the Optionee shall, if the Optionee is then deceased, be given to the Optionee’s personal representative if such representative has previously informed the Company of such representative’s status and address by written notice under this Section 5.6.

5.9 Notification of Disposition. If this Option is designated as an Incentive Stock Option, the Optionee shall give prompt notice to the Company of any disposition or other transfer of any shares of stock acquired under this Agreement if such disposition or transfer is made (a) within two (2) years from the Date of Grant with respect to such shares or (b) within one (1) year after the transfer of such shares to him. Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by the Optionee in such disposition or other transfer.
