If the Committee provides, in its discretion, that any Stock Option is exercisable subject to certain limitations (including, without limitation, that such Stock Option is exercisable only in installments or within certain time periods), the Committee may waive such limitations on the exercisability at any time at or after grant in whole or in part (including, without limitation, waiver of the installment exercise provisions or acceleration of the time at which such Stock Option may be exercised), based on such factors, if any, as the Committee shall determine, in its sole discretion. Unless otherwise determined by the Committee at grant, (i) in the event the Participant engages in Detrimental Activity prior to any exercise of the Stock Option, all Stock Options held by the Participant shall thereupon terminate and expire, (ii) as a condition of the exercise of a Stock Option, the Participant shall be required to certify (or shall be deemed to have certified) at the time of exercise in a manner acceptable to the Company that the Participant is in compliance with the terms and conditions of the Plan and that the Participant has not engaged in, and does not intend to engage in, any Detrimental Activity, and (iii) in the event the Participant engages in Detrimental Activity during the one year period commencing on the date the Stock Option is exercised, the Company shall be entitled to recover from the Participant at any time, and the Participant shall pay over to the Company, an amount equal to any gain realized as a result of the exercise (whether at the time of exercise or thereafter). The foregoing provisions relating to Detrimental Activity shall cease to apply upon a Change in Control.

(d) Method of Exercise. Subject to whatever installment exercise, waiting period and vesting provisions apply under sub-section (c) above, a Stock Option may be exercised in whole or in part at any time and from time to time during the Stock Option term by giving written notice of exercise to the Committee specifying the number of shares to be purchased. Such notice shall be accompanied by payment in full of the purchase price as follows: (i) in cash or by check, bank draft or money order payable to the order of the Company; (ii) if the Common Stock is traded on a national securities exchange, The Nasdaq Stock Market, Inc. or quoted on a national quotation system sponsored by the National Association of Securities Dealers, and the Committee authorizes, through a “cashless exercise” procedure whereby the Participant delivers irrevocable instructions to a broker approved by the Committee to deliver promptly to the Company an amount equal to the purchase price; or (iii) on such other terms and conditions as may be acceptable to the Committee (including, without limitation, the relinquishment of Stock Options or by payment in full or in part in the form of Common Stock owned by the Participant for a period of at least 6 months or such other period necessary to avoid a charge, for accounting purposes, against the Company’s earnings as reported in the Company’s financial statements (and for which the Participant has good title free and clear of any liens and encumbrances) based on the Fair Market Value of the Common Stock on the payment date as determined by the Committee). No shares of Common Stock shall be issued until

payment therefor, as provided herein, has been made or provided for and the conditions of Section 12.6 are satisfied.

(e) Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined as of the time of grant) of the Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an Eligible Employee during any calendar year under this Plan and/or any other stock option plan of the Company, any Subsidiary or any Parent exceeds $100,000, such Options shall be treated as Non-Qualified Stock Options. In addition, if an Eligible Employee does not remain employed by the Company, any Subsidiary or any Parent at all times from the time an Incentive Stock Option is granted until 3 months prior to the date of exercise thereof (or such other period as required by applicable law), such Stock Option shall be treated as a Non-Qualified Stock Option. Should any provision of this Plan not be necessary in order for the Stock Options to qualify as Incentive Stock Options, or should any additional provisions be required, the Committee may amend this Plan accordingly, without the necessity of obtaining the approval of the stockholders of the Company.

(f) Form, Modification, Extension and Renewal of Stock Options. Subject to the terms and conditions and within the limitations of this Plan, Stock Options shall be evidenced by such form of agreement or grant as is approved by the Committee, and the Committee may (i) modify, extend or renew outstanding Stock Options granted under this Plan (provided that the rights of a Participant are not reduced without the Participant’s consent), and (ii) accept the surrender of outstanding Stock Options (up to the extent not theretofore exercised) and authorize the granting of new Stock Options in substitution therefor (to the extent not theretofore exercised). Notwithstanding the foregoing, an outstanding Stock Option may not be modified to reduce the exercise price thereof nor may a new Stock Option at a lower exercise price be substituted for a surrendered Stock Option, provided that the foregoing shall not apply to adjustments or substitutions made in accordance with Section 4.2 hereof.

(g) Deferred Delivery of Common Shares. The Committee may in its discretion permit Participants to defer delivery of Common Stock acquired pursuant to a Participant’s exercise of an Option in accordance with the terms and conditions established by the Committee.

(h) Early Exercise. The Committee may provide that a Stock Option include a provision whereby the Participant may elect at any time before the Participant’s Termination to exercise the Stock Option as to any part or all of the shares of Common Stock subject to the Stock Option prior to the full vesting of the Stock Option. Any unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Committee determines to be appropriate.

(i) Other Terms and Conditions. Stock Options may contain such other provisions, which shall not be inconsistent with any of the terms of this Plan, as the Committee shall deem appropriate.

ARTICLE VII

NON-TRANSFERABILITY AND TERMINATION

7.1 Non-Transferability.

(a) Except as otherwise specifically provided herein, no Stock Option or Common Stock acquired pursuant to the exercise of a Stock Option shall be Transferable by the Participant otherwise than by will or by the laws of descent and distribution. All Stock Options shall be exercisable, during the Participant’s lifetime, only by the Participant. Any attempt to Transfer any such Stock Option shall be void and immediately cancelled, and no such Stock Option shall in any manner be liable for or subject to the debts, contracts, liabilities, engagements or torts of any person who shall be entitled to such Stock Option, nor shall it be subject to attachment or legal process for or against such person.

(b) Notwithstanding the foregoing, (i) the Committee may determine at the time of grant or thereafter that a Non-Qualified Stock Option that is otherwise not Transferable pursuant to this Section 7.1 is Transferable to a Family Member in whole or in part and in such circumstances, and under such conditions, as specified by the Committee and (ii) unless otherwise determined at the time of grant or thereafter, Common Stock acquired upon exercise of a Non-Qualified Stock Option is Transferable in accordance with the provisions of Article X. A Non-Qualified Stock Option that is Transferred to a Family Member pursuant to the preceding sentence (i) may not be subsequently Transferred otherwise than by will or by the laws of descent and distribution and (ii) remains subject to the terms of this Plan and the Stock Option agreement. Any shares of Common Stock acquired upon the exercise of a Stock Option by a permissible transferee of a Stock Option or a permissible transferee pursuant to a Transfer after the exercise of the Stock Option shall be subject to the terms of this Plan and the Stock Option agreement, including, without limitation, the provisions of Article X hereof.

7.2 Termination. The following rules apply with regard to the Termination of a Participant. Unless otherwise determined by the Committee at grant or, if no rights of the Participant are reduced, thereafter:

(a) Termination Other than for Cause. If a Participant’s Termination is for any reason other than for Cause, all Stock Options that are held by such Participant that are vested and exercisable at the time of the Participant’s Termination may be exercised by the Participant (or, in the case of death, by the legal representative of the Participant’s estate) at anytime within a period of 30 days from the date of such Termination, but in no event beyond the expiration of the stated terms of such Stock Options.

(b) Termination for Cause. If a Participant’s Termination (x) is for Cause or (y) is a voluntary Termination at any time within a period of 90 days after the Company’s discovery of an event which would be grounds for a Termination for Cause, all Stock Options, whether vested or not vested, that are

held by such Participant shall be forfeited and shall thereupon terminate and expire as of the date of such Termination.

(c) Unvested Stock Options. Stock Options that are not vested as of the date of a Participant’s Termination for any reason shall be forfeited and shall terminate and expire as of the date of such Termination.

ARTICLE VIII

CHANGE IN CONTROL PROVISIONS

8.1 Benefits. In the event of a Change in Control of the Company, except as otherwise provided by the Committee in a Stock Option agreement, a Participant’s employment agreement with the Company or an Affiliate, as approved by the Committee, or other written agreement approved by the Committee (as such agreement may be amended from time to time), a Participant’s unvested Stock Options shall not vest and a Participant’s Stock Option shall be treated in accordance with one of the following methods as determined by the Committee:

(a) Stock Options, whether or not then vested, shall be continued, assumed, have new rights substituted therefor or treated in accordance with Section 4.2 hereof, as determined by the Committee.

(b) The Committee, in its sole discretion, may provide for the purchase of any Stock Option for an amount of cash equal to the excess of the Change in Control Price (as defined below) of the shares of Common Stock covered by such Stock Options, over the aggregate exercise price of such Stock Options. For purposes of this Section 8.1, Change in Control Price shall mean the highest price per share of Common Stock paid in any transaction related to the applicable Change in Control of the Company.

(c) Notwithstanding anything else herein, the Committee may, in its sole discretion, provide for accelerated vesting of a Stock Option at any time.

(d) If the Company and the other party to a transaction constituting a Change in Control agree that such transaction shall be treated as a “pooling of interests” for financial reporting purposes, and if the transaction is in fact so treated, then the acceleration of exercisability, vesting or lapse of the vesting period of a Stock Option or of the applicable Restriction Period shall not occur to the extent that the Company’s independent public accountants determine in good faith that such acceleration would preclude “pooling of interests” accounting.

8.2 Change in Control. Unless otherwise determined by the Committee in the applicable Stock Option agreement or other written agreement approved by the Committee, a “Change in Control” shall be deemed to have occurred:

(a) upon any “person” as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Company, any trustee or other fiduciary holding securities under any employee benefit plan of the Company, or any company owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of Common Stock of the Company),

becoming the beneficial owner (as defined in Rule 13d-3under the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities;

(b) a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than 50% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; provided, however, that a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person (other than those covered by the exceptions in (a) above) acquires more than 50% of the combined voting power of the Company’s then outstanding securities shall not constitute a Change in Control of the Company; or

(c) upon the stockholders of the Company approval of a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets other than the sale or disposition of all or substantially all of the assets of the Company to a person or persons who beneficially own, directly or indirectly, at least 50% or more of the combined voting power of the outstanding voting securities of the Company at the time of the sale.

8.3 Public Offering not a Change in Control. For purposes of the Plan, a Public Offering shall not be deemed to be a Change in Control.

ARTICLE IX

TERMINATION OR AMENDMENT OF PLAN

Notwithstanding any other provision of this Plan, the Board or the Committee may at any time, and from time to time, amend, in whole or in part, any or all of the provisions of this Plan (including any amendment deemed necessary to ensure that the Company may comply with any regulatory requirement referred to in Article XII), or suspend or terminate it entirely, retroactively or otherwise; provided, however, that, unless otherwise required by law or specifically provided herein, the rights of a Participant with respect to Stock Options granted prior to such amendment, suspension or termination, may not be impaired without the consent of such Participant and, provided further, without the approval of the stockholders of the Company in accordance with the laws of the State of Delaware, solely to the extent required by the applicable provisions of Rule 16b-3, or, solely to the extent applicable to Incentive Stock Options, Section 422 of the Code, no amendment may be made which would (i) increase the aggregate number of shares of Common Stock that may be issued under this Plan; (ii) change the classification of employees, Consultants or Non-Employee Directors eligible to receive Stock Options under this Plan; (iii) decrease the minimum option price of any Stock Option; or (iv) extend the maximum Stock Option period under Section 6.3. In no event may this Plan be amended without the approval of the stockholders of the Company in accordance with the applicable laws of the State of Delaware to increase the aggregate number of shares of Common

Stock that may be issued under this Plan, decrease the minimum exercise price of any Stock Option, or to make any other amendment that would require stockholder approval under the rules of any exchange or system on which the Company’s securities are listed or traded at the request of the Company.

The Committee may amend the terms of any Stock Option theretofore granted, prospectively or retroactively, but, subject to Article IV above or as otherwise specifically provided herein, no such amendment or other action by the Committee shall impair the rights of any holder without the holder’s consent.

ARTICLE X

RIGHTS OF FIRST OFFER AND REPURCHASE

To the extent provided in the Stockholders Agreement, the shares of Common Stock acquired by a Participant pursuant to the exercise of a Stock Option are subject to rights of first offer and other Transfer restrictions contained in the Stockholders Agreement and the Company’s right to repurchase all or a portion of the shares of Common Stock upon a Participant’s Termination.

ARTICLE XI

UNFUNDED PLAN

This Plan is intended to constitute an “unfunded” plan for incentive and deferred compensation. With respect to any payments as to which a Participant has a fixed and vested interest but which are not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general unsecured creditor of the Company.

ARTICLE XII

GENERAL PROVISIONS

12.1 Legend. The Committee may require each person receiving shares pursuant to a Stock Option under this Plan to represent to and agree with the Company in writing that the Participant is acquiring the shares without a view to distribution thereof and such other securities law related representations as the Committee shall request. In addition to any legend required by this Plan, the certificates for such shares may include any legend which the Committee deems appropriate to reflect any restrictions on Transfer.

All certificates for shares of Common Stock delivered under this Plan shall be subject to such stock transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations and other requirements of the Securities and Exchange Commission, any stock exchange upon which the Common Stock is then listed or any national securities association system upon whose system the Common Stock is then quoted, any applicable Federal or state securities law, and any applicable corporate

law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

12.2 Other Plans. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases. In the event of any conflict between the provisions of this Plan and any agreement (including any Stock Option agreement) approved by the Board or the Committee, between the Company and any Eligible Employee, Consultant or Non-Employee Director, the provisions of such agreement shall govern.

12.3 No Right to Employment/Directorship/Consultancy. Neither this Plan nor the grant of any Stock Option hereunder shall give any Participant or other employee, Consultant or Non-Employee Director any right with respect to continuance of employment, consultancy or directorship by the Company or any Affiliate, nor shall they be a limitation in any way on the right of the Company or any Affiliate by which an employee is employed or a Consultant or Non-Employee Director is retained to terminate his or her employment or consultancy at anytime.

12.4 Withholding of Taxes. The Company shall have the right to deduct from any payment to be made to a Participant, or to otherwise require, prior to the issuance or delivery of any shares of Common Stock or the payment of any cash hereunder, payment by the Participant of, any Federal, state or local taxes required by law to be withheld.

Any statutorily required withholding obligation with regard to any Eligible Employee may be satisfied, subject to the consent of the Committee, by reducing the number of shares of Common Stock otherwise deliverable or by delivering shares of Common Stock already owned. Any fraction of a share of Common Stock required to satisfy such tax obligations shall be disregarded and the amount due shall be paid instead in cash by the Participant.

12.5 Listing and Other Conditions.

(a) Unless otherwise determined by the Committee, as long as the Common Stock is listed on a national securities exchange or system sponsored by a national securities association, the issue of any shares of Common Stock pursuant to a Stock Option shall be conditioned upon such shares being listed on such exchange or system. The Company shall have no obligation to issue such shares unless and until such shares are so listed, and the right to exercise any Stock Option with respect to such shares shall be suspended until such listing has been effected.

(b) If at any time counsel to the Company shall be of the opinion that any sale or delivery of shares of Common Stock pursuant to a Stock Option is or may in the circumstances be unlawful or result in the imposition of excise taxes on the Company under the statutes, rules or regulations of any applicable jurisdiction, the Company shall have no obligation to make such sale or delivery, or to make any application or to effect or to maintain any qualification or registration under the Securities Act or otherwise with respect to shares of Common Stock or Stock Options, and the right to exercise any Stock Option shall be suspended until, in

the opinion of said counsel, such sale or delivery shall be lawful and will not result in the imposition of excise taxes on the Company.

(c) Upon termination of any period of suspension under this Section 12.5, a Stock Option affected by such suspension which shall not then have expired or terminated shall be reinstated as to all shares available before such suspension and as to shares which would otherwise have become available during the period of such suspension, but no such suspension shall extend the term of any Stock Option.

(d) A Participant shall be required to supply the Company with any certificates, representations and information that the Company requests and otherwise cooperate with the Company in obtaining any listing, registration, qualification, exemption, consent or approval the Company deems necessary or appropriate.

12.6 Stockholders Agreement and Other Requirements.

To the extent applicable, this Plan shall be limited, construed and interpreted in a manner so as to comply with the applicable requirements of Rule 16b-3; however, noncompliance with Rule 16b-3 shall have no impact on the effectiveness of a Stock Option under this Plan.

The Committee may in its discretion require the transferee of a Participant to supply it with written notice of the Participant’s death or Disability and to supply it with a copy of the will (in the case of the Participant’s death) or such other evidence as the Committee deems necessary to establish the validity of the Transfer of a Stock Option. The Committee may also require that the agreement of the transferee to be bound by all of the terms and conditions of this Plan.

12.13 Section 16(b) of the Exchange Act. On and after a Public Offering, all elections and transactions under this Plan by persons subject to Section 16 of the Exchange Act involving shares of Common Stock are intended to comply with any applicable exemptive condition under Rule 16b-3. The Committee may establish and adopt written administrative guidelines, designed to facilitate compliance with Section 16(b) of the Exchange Act, as it may deem necessary or proper for the administration and operation of this Plan and the transaction of business thereunder.

12.14 Severability of Provisions. If any provision of this Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions hereof, and this Plan shall be construed and enforced as if such provisions had not been included; provided, however, that if the provisions set forth in Article X shall be held invalid or unenforceable, the Stock Options granted under the Plan shall be cancelled and terminated.

12.15 Headings and Captions. The headings and captions herein are provided for reference and convenience only, shall not be considered part of this Plan, and shall not be employed in the construction of this Plan.

12.16 Securities Act Compliance. Except as the Company or Committee shall otherwise determine, this Plan is intended to comply with Section 4(2) or Rule 701 under the Securities Act, and any provisions inconsistent with such Section or Rule of the Securities Act shall be inoperative and shall not affect the validity of the Plan.

12.17 Successors and Assigns. The Plan shall be binding on all successors and permitted assigns of a Participant, including, without limitation, the estate of such Participant and the executor, administrator or trustee of such estate.

12.19 Agreement. As a condition to the grant of a Stock Option, if requested by the Company and the lead underwriter of any Public Offering of the Common Stock (the

“Lead Underwriter”), a Participant shall irrevocably agree not to sell, contract to sell, grant any option to purchase, transfer the economic risk of ownership in, make any short sale of, pledge or otherwise transfer or dispose of, any interest in any Common Stock or any securities convertible into, derivative of, or exchangeable or exercisable for, or any other rights to purchase or acquire Common Stock (except Common Stock included in such Public Offering or acquired on the public market after such offering) during such period of time following the effective date of a registration statement of the Company filed under the Securities Act that the Lead Underwriter shall specify (the “Lock-up Period”).
