6.3 Exercise Price . The per share price to be paid by a Participant upon exercise of an Option granted pursuant to this Section 6 will be determined by the Committee in its sole discretion at the time of the Option grant; provided , however , that such price will not be less than one hundred percent (100%) of the Fair Market Value of one share of Common Stock on the Grant Date (one hundred and ten percent (110%) of the Fair Market Value if, at the time the Incentive Stock Option is granted, the Participant owns, directly or indirectly, more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company).

6.4 Exercisability and Duration . An Option will become exercisable at such times and in such installments and upon such terms and conditions as may be determined by the Committee in its sole discretion at the time of grant, including (i) the achievement of one or more of the Performance Goals; or that (ii) the Participant remain in the continuous employment or service with the Company or a Subsidiary for a certain period; provided , however , that no Option may be exercisable after ten (10) years from the Grant Date (five (5) years from the Grant Date in the case of an Incentive Stock Option that is granted to a Participant who owns, directly or indirectly, more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company). Notwithstanding the foregoing, if the exercise of an Option that is exercisable in accordance with its terms is prevented by the provisions of Section 19, the Option will remain exercisable until thirty (30) days after the date such exercise first would no longer be prevented by such provisions, but in any event no later than the expiration date of such Option.

13

6.5 Payment of Exercise Price .

(a) The total purchase price of the shares to be purchased upon exercise of an Option will be paid entirely in cash (including check, bank draft or money order); provided , however , that the Committee, in its sole discretion and upon terms and conditions established by the Committee, may allow such payments to be made, in whole or in part, by (i) tender of a Broker Exercise Notice; (ii) by tender, either by actual delivery or attestation as to ownership, of Previously Acquired Shares; (iii) a “net exercise” of the Option (as further described in paragraph (b), below); (iv) by a combination of such methods; or (v) any other method approved or accepted by the Committee in its sole discretion. Notwithstanding any other provision of the Plan to the contrary, no Participant who is a Director or an “executive officer” of the Company within the meaning of Section 13(k) of the Exchange Act shall be permitted to make payment with respect to any Incentive Awards granted under the Plan, or continue any extension of credit with respect to such payment with a loan from the Company or a loan arranged by the Company in violation of Section 13(k) of the Exchange Act.

(b) In the case of a “net exercise” of an Option, the Company will not require a payment of the exercise price of the Option from the Participant but will reduce the number of shares of Common Stock issued upon the exercise by the largest number of whole shares that has a Fair Market Value on the exercise date that does not exceed the aggregate exercise price for the shares exercised under this method. Shares of Common Stock will no longer be outstanding under an Option (and will therefore not thereafter be exercisable) following the exercise of such Option to the extent of (i) shares used to pay the exercise price of an Option under the “net exercise,” (ii) shares actually delivered to the Participant as a result of such exercise and (iii) any shares withheld for purposes of tax withholding pursuant to Section 16 of this Plan.

(c) For purposes of such payment, Previously Acquired Shares tendered or covered by an attestation will be valued at their Fair Market Value on the exercise date of the Option.

6.6 Manner of Exercise . An Option may be exercised by a Participant in whole or in part from time to time, subject to the conditions contained in this Plan and in the Incentive Award Agreement evidencing such Option, by delivery in person, by facsimile or electronic transmission or through the mail of written notice of exercise to the Company at its principal executive office in The Woodlands, Texas (or to the Company’s designee as may be established from time to time by the Company and communicated to Participants) and by paying in full the total exercise price for the shares of Common Stock to be purchased in accordance with Section 6.5 of this Plan.

8.6 Enforcement of Restrictions . To enforce the restrictions referred to in this Section 8, the Committee may place a legend on the stock certificates representing Restricted Stock Awards referring to such restrictions and may require the Participant, until the restrictions have lapsed, to keep the stock certificates, together with duly endorsed stock powers, in the custody of the Company or its transfer agent, or to maintain evidence of stock ownership, together with duly endorsed stock powers, in a certificateless book entry stock account with the Company’s transfer agent. Alternatively, Restricted Stock Awards may be held in non-certificated form pursuant to such terms and conditions as the Company may establish with its registrar and transfer agent or any third-party administrator designated by the Company to hold Restricted Stock Awards on behalf of Participants.

Any Performance Measure Element can be a Performance Measure. In addition, any of the Performance Measure Element(s) can be used in an algebraic formula (e.g., averaged over a period, combined into a ratio, compared to a budget or standard, compared to previous periods or other formulaic combinations) based on the Performance Measure Elements to create a Performance Measure. Any Performance Measure(s) may be used to measure the performance of the Company or Subsidiary as a whole or any division or business unit of the Company, product or product group, region or territory, or Subsidiary, or any combination thereof, as the Committee may deem appropriate. Any Performance Measure(s) can be compared to the performance of a peer group, or published or special index that the Committee, in its sole discretion, deems appropriate, or the Company may select any Performance Measure(s) above as compared to various stock market indices. The Committee also has the authority to provide for accelerated vesting of any Incentive Award based on the achievement of Performance Goals pursuant to any Performance Measure(s) specified in this Section 13.1.

13.2 Establishment of Performance Goals . Any Incentive Award to a Covered Employee that is intended to qualify as Performance-Based Compensation will be granted, and Performance Goals for such an Incentive Award will be established, by the Committee in writing not later than ninety (90) days after the commencement of the Performance Period to which the Performance Goals relate, or such other period required under Section 162(m) of the Code; provided that the outcome is substantially uncertain at the time the Committee establishes the Performance Goal; and provided further that in no event will a Performance Goal be considered to be pre-established if it is established after twenty-five percent (25%) of the Performance Period (as scheduled in good faith at the time the Performance Goal is established) has elapsed.

13.3 Certification of Payment . Before any payment is made in connection with any Incentive Award to a Covered Employee that is intended to qualify as Performance-Based Compensation, the Committee must certify in writing, as reflected in the minutes, that the Performance Goals established with respect to such Incentive Award have been achieved.

13.5 Adjustment of Performance Goals, Performance Periods or other Vesting Criteria . Subject to Section 13.6, the Committee may amend or modify the vesting criteria (including any Performance Goals, Performance Measures or Performance Periods) of any outstanding Incentive Awards based in whole or in part on the financial performance of the Company (or any Subsidiary or division, business unit or other sub-unit thereof) in recognition of unusual or nonrecurring events (including the events described in Section 4.5(a) hereof) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent unintended dilution or enlargement of the benefits or potential benefits intended to be made available under this Plan. The determination of the Committee as to the foregoing adjustments, if any, shall be final, conclusive and binding on Participants under this Plan. For all Awards intended to qualify as Performance-Based Compensation, such determinations shall be made within the time prescribed by, and otherwise in compliance with, Section 162(m) of the Code.

13.6 Adjustment of Performance-Based Compensation . Incentive Awards that are intended to qualify as Performance-Based Compensation may not be adjusted upward. The Committee will retain the discretion to adjust such Incentive Awards downward, either on a formula or discretionary basis or any combination, as the Committee determines.

13.7 Committee Discretion . In the event that applicable tax or securities laws change to permit Committee discretion to alter the governing Performance Measures without obtaining stockholder approval of such changes, the Committee will have sole discretion to make such changes without obtaining stockholder approval. In addition, in the event that the Committee determines that it is advisable to grant Incentive Awards that will not qualify as Performance-Based Compensation, the Committee may make such grants without satisfying the requirements of Section 162(m) of the Code and base vesting on Performance Measures other than those set forth in Section 13.1.

22

14. Dividend Equivalents .

Any Participant selected by the Committee may be granted dividend equivalents based on the dividends declared on shares of Common Stock that are subject to any Incentive Award, to be credited as of dividend payment dates, during the period between the date the Incentive Award is granted and the date the Incentive Award is exercised, vests or expires, as determined by the Committee. Such dividend equivalents will be converted to cash or additional shares of Common Stock by such formula and at such time and subject to such limitations as may be determined by the Committee. Notwithstanding the foregoing, the Committee may not grant dividend equivalents based on the dividends declared on shares of Common Stock that are subject to an Option or Stock Appreciation Right and further, no dividend or dividend equivalents will be paid out with respect to any unvested Incentive Awards, the vesting of which is based on the achievement of Performance Goals.

23

partial fiscal years. The Committee will consider the provisions of Section 15.5 of this Plan and will have the discretion to consider any other fact or circumstance in making its decision as to whether to deliver such shares of Common Stock or other payment, including whether the Participant again becomes employed; and

(d) If the effective date of such termination is before the end of the Performance Period to which an Annual Performance Cash Award relates, then any such Annual Performance Cash Award held by a Participant will be terminated and forfeited; if the effective date of such termination is on or after the end of the Performance Period to which an Annual Performance Cash Award relates, then any such Annual Performance Cash Award held by a Participant will be paid to the Participant in accordance with the payment terms of such Award.

15.2 Termination for Reasons Other than Death, Disability or Retirement . Unless otherwise expressly provided by the Committee in its sole discretion in an Incentive Award Agreement, and subject to Sections 15.4 and 15.5 of this Plan, in the event a Participant’s employment or other service with the Company and all Subsidiaries is terminated for any reason other than death, Disability or Retirement:

(a) All outstanding Options (including Non-Employee Director Options) and Stock Appreciation Rights held by the Participant as of the effective date of such termination will, to the extent exercisable as of such termination, remain exercisable for a period of three months after such termination (but in no event after the expiration date of any such Option or Stock Appreciation Right) and Options and Stock Appreciation Rights not exercisable as of such termination will be terminated and forfeited.

(b) All Restricted Stock Awards held by the Participant as of the effective date of such termination that have not vested as of such termination will be terminated and forfeited;

24

become free of restrictions and conditions to payment, as the case may be, following such termination of employment or service, in each case in the manner determined by the Committee; provided , however , that (a) no Option or Stock Appreciation Right may remain exercisable beyond its expiration date; (b) the Committee may not take any action not permitted pursuant to Section 13.6; (c) the Committee taking any such action relating to Non-Employee Director Awards will consist solely of “independent directors” as defined in the NASDAQ Listing Rules (or other applicable exchange or market on which the Common Stock may be traded or quoted); and (d) any such action by the Committee adversely affecting any outstanding Incentive Award will not be effective without the consent of the affected Participant (subject to the right of the Committee to take whatever action it deems appropriate under Section 4.5, 15.5, 17 or 21).

15.4 Determination of Termination of Employment or Other Service .

(a) The change in a Participant’s status from that of an Employee to that of a Consultant will, for purposes of this Plan, be deemed to result in a termination of such Participant’s employment with the Company and its Subsidiaries, unless the Committee otherwise determines in its sole discretion.

(b) The change in a Participant’s status from that of a Consultant to that of an Employee will not, for purposes of this Plan, be deemed to result in a termination of such Participant’s service as a Consultant, and such Participant will thereafter be deemed to be an Employee until such Participant’s employment is terminated, in which event such Participant will be governed by the provisions of this Plan relating to termination of employment or service (subject to paragraph (a) above).

(c) Unless the Committee otherwise determines in its sole discretion, a Participant’s employment or other service will, for purposes of this Plan, be deemed to have terminated on the date recorded on the personnel or other records of the Company or the Subsidiary for which the Participant provides employment or other service, as determined by the Committee in its sole discretion based upon such records.

(d) Notwithstanding the foregoing, if payment of an Incentive Award that is subject to Section 409A of the Code is triggered by a termination of a Participant’s employment or other service, such termination must also constitute a “separation from service” within the meaning of Section 409A of the Code, and any change in employment status that constitutes a “separation from service” under Section 409A of the Code will be treated as a termination of employment or service, as the case may be.

15.5 Additional Forfeiture Events .

(a) Effect of Actions Constituting Cause or Adverse Action . Notwithstanding anything in this Plan to the contrary and in addition to the other rights of the Committee under this Section 15.5, if a Participant is determined by the Committee, acting in its sole discretion, to have taken any action that would constitute Cause or an Adverse Action during or after the termination of employment or other service with the Company or a Subsidiary, irrespective of whether such action or the Committee’s determination occurs before or after termination of such Participant’s employment or other service with the

25

Company or any Subsidiary and irrespective of whether or not the Participant was terminated as a result of such Cause or Adverse Action, (i) all rights of the Participant under this Plan and any Incentive Award Agreements evidencing an Incentive Award then held by the Participant will terminate and be forfeited without notice of any kind, and (ii) the Committee in its sole discretion will have the authority to rescind the exercise, vesting or issuance of, or payment in respect of, any Incentive Awards of the Participant that were exercised, vested or issued, or as to which such payment was made, and to require the Participant to pay to the Company, within ten (10) days of receipt from the Company of notice of such rescission, any amount received or the amount of any gain realized as a result of such rescinded exercise, vesting, issuance or payment (including any dividends paid or other distributions made with respect to any shares subject to any Incentive Award). The Company may defer the exercise of any Option or Stock Appreciation Right for a period of up to six (6) months after receipt of the Participant’s written notice of exercise or the issuance of share certificates upon the vesting of any Incentive Award for a period of up to six (6) months after the date of such vesting in order for the Committee to make any determination as to the existence of Cause or an Adverse Action. The Company will be entitled to withhold and deduct from future wages of the Participant (or from other amounts that may be due and owing to the Participant from the Company or a Subsidiary) or make other arrangements for the collection of all amounts necessary to satisfy such payment obligations. Unless otherwise provided by the Committee in an applicable Incentive Award Agreement, this Section 15.5(a) will not apply to any Participant following a Change in Control.

(b) Forfeiture of Incentive Awards . If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under the securities laws, then any Participant who is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002 will reimburse the Company for the amount of any Incentive Award received by such individual under this Plan during the 12-month period following the first public issuance or filing with the Securities and Exchange Commission, as the case may be, of the financial document embodying such financial reporting requirement. In addition, all Awards under this Plan will be subject to forfeiture or other penalties pursuant to any clawback or forfeiture policy of the Company, as in effect from time to time, and such forfeiture and/or penalty conditions or provisions as determined by the Committee and set forth in the applicable Award Agreement. In addition, the Company may seek to recover any Incentive Award made as required by the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act or any other clawback, forfeiture or recoupment provision required by Applicable Law or under the requirements of any stock exchange or market upon which the shares of Common Stock are then listed or traded.

16. Payment of Withholding Taxes .

16.1 General Rules . The Company is entitled to (a) withhold and deduct from future wages of the Participant (or from other amounts that may be due and owing to the Participant from the Company or a Subsidiary), or make other arrangements for the collection of, all legally required amounts necessary to satisfy any and all federal, foreign, state and local withholding

26

and employment related tax requirements attributable to an Incentive Award, including the grant, exercise, vesting or settlement of, or payment of dividends with respect to, an Incentive Award or a disqualifying disposition of stock received upon exercise of an Incentive Stock Option, or (b) require the Participant promptly to remit the amount of such withholding to the Company before taking any action, including issuing any shares of Common Stock, with respect to an Incentive Award. When withholding shares of Common Stock for taxes is effected under this Plan, it shall be withheld only up to an amount based on the maximum statutory tax rates in the Participant’s applicable tax jurisdiction or such other rate that will not trigger a negative accounting impact on the Company.

16.2 Special Rules . The Committee may, in its sole discretion and upon terms and conditions established by the Committee, permit or require a Participant to satisfy, in whole or in part, any withholding or employment related tax obligation described in Section 16.1 of this Plan by withholding shares of Common Stock underlying an Award, by electing to tender, or by attestation as to ownership of, Previously Acquired Shares, by delivery of a Broker Exercise Notice or a combination of such methods. For purposes of satisfying a Participant’s withholding or employment-related tax obligation, shares of Common Stock withheld by the Company or Previously Acquired Shares tendered or covered by an attestation will be valued at their Fair Market Value.

17. Change in Control .

17.1 Change in Control . For purposes of this Section 17, a “ Change in Control ” of the Company will mean (a) the consummation by the Company (whether directly involving the Company or indirectly involving the Company through one or more intermediaries) of (i) a merger, consolidation, reorganization, or business combination, (ii) a sale or other disposition of all or substantially all of the Company’s assets in any single transaction or series of related transactions or (iii) the acquisition of assets or stock of another entity, in each case, other than a transaction which (x) results in the Company’s voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the Company or the person that, as a result of the transaction, controls, directly or indirectly, the Company or owns, directly or indirectly, all or substantially all of the Company’s assets or otherwise succeeds to the business of the Company (the Company or such person, the “ Successor Entity ”)) directly or indirectly, at least a majority of the combined voting power of the Successor Entity’s outstanding voting securities immediately after the transaction, and (y) after which no person or group beneficially owns voting securities representing fifty percent (50%) or more of the combined voting power of the Successor Entity; provided, however, that no person or group shall be treated for purposes of this Section 17.1(a)(iii)(y) as beneficially owning fifty percent (50%) or more of the combined voting power of the Successor Entity solely as a result of the voting power held in the Company prior to the consummation of the transaction, (b) the approval by the stockholders of the Company of any plan or proposal for the liquidation or dissolution of the Company, (c) any Person, other than Clearlake Capital Partners II (Master), L.P. or any of its affiliates, becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) directly or indirectly, of 50% or more of the combined voting power of the Company’s outstanding securities ordinarily having the right to vote at elections of directors in one transaction or a series of related transactions or (d) individuals who constitute the Board on the Effective Date of this Plan cease for any reason to constitute at least a

27

majority thereof, provided that any person becoming a director subsequent to the Effective Date of this Plan whose election, or nomination for election by the Company’s stockholders, was approved by a vote of at least a majority of the directors comprising the Board on the Effective Date of this Plan (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for director, without objection to such nomination) will be, for purposes of this clause (d), considered as though such person were a member of the Board on the Effective Date of this Plan unless such person’s initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of Directors or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board.

17.2 Acceleration of Vesting . Without limiting the authority of the Committee under Sections 3.2 and 4.5 or 17.3 of this Plan, if a Change in Control of the Company occurs, then, unless otherwise provided by the Committee in its sole discretion either in the Incentive Award Agreement evidencing an Incentive Award at the time of grant or at any time after the grant of an Incentive Award the following provisions will apply:

(a) If the Successor Entity does not assume the outstanding Incentive Awards or does not substitute equivalent equity awards relating to the securities of such Successor Entity or its affiliates for such Incentive Awards, then prior to the Change in Control (a) all outstanding Options and Stock Appreciation Rights will become immediately exercisable in full and will remain exercisable until immediately prior to the consummation of the Change in Control and terminate upon consummation of the Change in Control; (b) all restrictions and vesting requirements applicable to any Incentive Award based solely on the continued service of the Participant will terminate; and (c) all Incentive Awards the vesting or payment of which are based on Performance Goals will vest as though such Performance Goals were fully achieved at target and will become immediately payable; provided , however , that no Incentive Award that provides for a deferral of compensation within the meaning of Section 409A of the Code will be cashed out upon the occurrence of a Change in Control unless the event or circumstances constituting the Change in Control also constitute a “change in the ownership” of the Company, a “change in the effective control” of the Company or a “change in the ownership of a substantial portion of the assets” of the Company, in each case as determined under Section 409A of the Code. The treatment of any other Incentive Awards in the event of a Change in Control will be as determined by the Committee in connection with the grant thereof, as reflected in the applicable Incentive Award Agreement.

(b) If the Successor Entity assumes the outstanding Incentive Awards or substitutes equivalent equity awards relating to the securities of such Successor Entity or its affiliates for such Incentive Awards, then all such Incentive Awards or such substitutes therefore shall remain outstanding and be governed by their respective terms and the provisions of the Plan or its successor.

28

17.3 Alternative Treatment of Stock-Based Awards . In connection with a Change in Control, the Committee in its sole discretion, either in an Incentive Award Agreement at the time of grant of a Stock-Based Award or at any time after the grant of such an Incentive Award, may determine that any or all outstanding Stock-Based Awards granted under this Plan, whether or not exercisable or vested, as the case may be, will be canceled and terminated and that in connection with such cancellation and termination the holder of such Stock-Based Award will receive for each share of Common Stock subject to such Incentive Award a cash payment (or the delivery of shares of stock, other securities or a combination of cash, stock and securities with a fair market value (as determined by the Committee in good faith) equivalent to such cash payment) equal to the difference, if any, between the consideration to be received by stockholders of the Company in respect of a share of Common Stock in connection with such Change in Control and the purchase price per share, if any, under the Incentive Award, multiplied by the number of shares of Common Stock subject to such Incentive Award (or in which such Incentive Award is denominated); provided that if such product is zero ($0) or less or to the extent that the Incentive Award is not then exercisable, the Incentive Award may be canceled and terminated without payment therefor; provided , however , that no Stock-Based Award that provides for a deferral of compensation within the meaning of Section 409A of the Code will be cashed out upon the occurrence of a Change in Control unless the event or circumstances constituting the Change in Control also constitute a “change in the ownership” of the Company, a “change in the effective control” of the Company or a “change in the ownership of a substantial portion of the assets” of the Company, in each case as determined under Section 409A of the Code. The treatment of any other Stock-Based Awards in the event of a Change in Control will be as determined by the Committee in connection with the grant thereof, as reflected in the applicable Award Agreement. If any portion of the consideration pursuant to a Change in Control may be received by holders of shares of Common Stock on a contingent or delayed basis, the Committee may, in its sole discretion, determine the fair market value per share of such consideration as of the time of the Change in Control on the basis of the Committee’s good faith estimate of the present value of the probable future payment of such consideration. Notwithstanding the foregoing, any shares of Common Stock issued pursuant to a Stock-Based Award that immediately prior to the effectiveness of the Change in Control are subject to no further restrictions pursuant to this Plan or an Incentive Award Agreement (other than pursuant to the securities laws) will be deemed to be outstanding shares of Common Stock and receive the same consideration as other outstanding shares of Common Stock in connection with the Change in Control.

17.4 Limitation on Change in Control Payments . Notwithstanding anything in Section 17.2 or 17.3 to the contrary, if, with respect to a Participant, the acceleration of the vesting of an Incentive Award as provided in Section 17.2 or the payment of cash in exchange for all or part of a Stock-Based Award as provided in Section 17.3 (which acceleration or payment could be deemed a “payment” within the meaning of Section 280G(b)(2) of the Code), together with any other “payments” that such Participant has the right to receive from the Company or any corporation that is a member of an “affiliated group” (as defined in Section 1504(a) of the Code without regard to Section 1504(b) of the Code) of which the Company is a member, would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the “payments” to such Participant pursuant to Section 17.2 or 17.3 will be reduced (or acceleration of vesting eliminated) to the largest amount as will result in no portion of such “payments” being subject to the excise tax imposed by Section 4999 of the Code; provided, that such reduction will be made only if the aggregate amount of the payments after such reduction exceeds the difference between (a) the amount of such payments absent such reduction minus (b) the aggregate amount of the excise tax imposed under Section 4999 of the Code attributable to any

29

such excess parachute payments; and provided further that such payments will be reduced (or acceleration of vesting eliminated) in the following order: (i) options with an exercise price above fair market value that have a positive value for purposes of Section 280G of the Code, (ii) pro rata among Incentive Awards that constitute deferred compensation under Section 409A of the Code, and (iii) finally, among the Incentive Awards that are not subject to Section 409A of the Code. Notwithstanding the foregoing sentence, if a Participant is subject to a separate agreement with the Company or an Affiliate or Subsidiary that expressly addresses the potential application of Section 280G or 4999 of the Code, then this Section 17.4 will not apply and any “payments” to a Participant pursuant to Section 17.2 or 17.3 will be treated as “payments” arising under such separate agreement.

18. Rights of Eligible Recipients and Participants; Transferability .

18.1 Employment . Nothing in this Plan or an Incentive Award Agreement will interfere with or limit in any way the right of the Company or any Subsidiary to terminate the employment or service of any Eligible Recipient or Participant at any time, nor confer upon any Eligible Recipient or Participant any right to continue employment or other service with the Company or any Subsidiary.

18.2 No Rights to Awards . No Participant or Eligible Recipient will have any claim to be granted any Incentive Award under this Plan.

18.3 Rights as a Stockholder . Except as otherwise provided herein, a Participant will have no rights as a stockholder with respect to shares of Common Stock covered by any Stock-Based Award unless and until the Participant becomes the holder of record of such shares.

(b) A Participant will be entitled to designate a beneficiary to receive an Incentive Award upon such Participant’s death, and in the event of such Participant’s death, payment of any amounts due under this Plan will be made to, and exercise of any Options or Stock Appreciation Rights (to the extent permitted pursuant to Section 15 of this Plan) may be made by, such beneficiary. If a deceased Participant has failed to designate a beneficiary, or if a beneficiary designated by the Participant fails to survive the Participant, payment of any amounts due under this Plan will be made to, and exercise of any Options or Stock Appreciation Rights (to the extent permitted pursuant to Section 15 of this Plan) may be made by, the Participant’s legal representatives, heirs and legatees. If a deceased Participant has designated a beneficiary and such beneficiary survives the Participant but dies before complete payment of all amounts due under this Plan or exercise of all exercisable Options or Stock Appreciation Rights, then such payments will be made to, and the exercise of such Options or Stock Appreciation Rights may be made by, the legal representatives, heirs and legatees of the beneficiary.

30

(c) Upon a Participant’s request, the Committee may, in its sole discretion, permit a transfer of all or a portion of a Non-Statutory Stock Option, other than for value, to such Participant’s 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, any person sharing such Participant’s household (other than a tenant or employee), a trust in which any of the foregoing have more than fifty percent (50%) of the beneficial interests, a foundation in which any of the foregoing (or the Participant) control the management of assets, and any other entity in which these persons (or the Participant) own more than fifty percent (50%) of the voting interests. Any permitted transferee will remain subject to all the terms and conditions applicable to the Participant prior to the transfer. A permitted transfer may be conditioned upon such requirements as the Committee may, in its sole discretion, determine, including execution or delivery of appropriate acknowledgements, opinion of counsel, or other documents by the transferee.

18.5 Non-Exclusivity of this Plan . Nothing contained in this Plan is intended to modify or rescind any previously approved compensation plans or programs of the Company or create any limitations on the power or authority of the Board to adopt such additional or other compensation arrangements as the Board may deem necessary or desirable.

19. Securities Law and Other Restrictions .

Notwithstanding any other provision of this Plan or any Incentive Award Agreements entered into pursuant to this Plan, the Company will not be required to issue any shares of Common Stock under this Plan, and a Participant may not sell, assign, transfer or otherwise dispose of shares of Common Stock issued pursuant to Incentive Awards granted under this Plan, unless (a) there is in effect with respect to such shares a registration statement under the Securities Act and any applicable securities laws of a state or foreign jurisdiction or an exemption from such registration under the Securities Act and applicable state or foreign securities laws, and (b) there has been obtained any other consent, approval or permit from any other U.S. or foreign regulatory body which the Committee, in its sole discretion, deems necessary or advisable. The Company may condition such issuance, sale or transfer upon the receipt of any representations or agreements from the parties involved, and the placement of any legends on certificates representing shares of Common Stock, as may be deemed necessary or advisable by the Company in order to comply with such securities law or other restrictions.

20. Deferred Compensation; Compliance with Section 409A .

It is intended that all Incentive Awards issued under the Plan be in a form and administered in a manner that will comply with the requirements of Section 409A of the Code, or the requirements of an exception to Section 409A of the Code, and the Incentive Award Agreements and this Plan will be construed and administered in a manner that is consistent with and gives effect to such intent. The Committee is authorized to adopt rules or regulations

31

deemed necessary or appropriate to qualify for an exception from or to comply with the requirements of Section 409A of the Code. With respect to an Incentive Award that constitutes a deferral of compensation subject to Code Section 409A: (i) if any amount is payable under such Incentive Award upon a termination of service, a termination of service will be treated as having occurred only at such time the Participant has experienced a “separation from service” as such term is defined for purposes of Code Section 409A; (ii) if any amount is payable under such Incentive Award upon a Disability, a Disability will be treated as having occurred only at such time the Participant has experienced a “disability” as such term is defined for purposes of Code Section 409A; (iii) if any amount is payable under such Incentive Award on account of the occurrence of a Change of Control, a Change of Control will be treated as having occurred only at such time a “change in the ownership or effective control of the corporation or in the ownership of a substantial portion of the assets of the corporation” as such terms are defined for purposes of Code Section 409A, (iv) if any amount becomes payable under such Incentive Award on account of a Participant’s separation from service at such time as the Participant is a “specified employee” within the meaning of Code Section 409A, then no payment shall be made, except as permitted under Code Section 409A, prior to the first business day after the earlier of (y) the date that is six months after the date of the Participant’s separation from service or (z) the Participant’s death, and (v) no amendment to or payment under such Incentive Award will be made except and only to the extent permitted under Code Section 409A.

21. Amendment, Modification and Termination .

21.1 Generally . Subject to other subsections of this Section 21 and Sections 3.4 and 21.3, the Board at any time may suspend or terminate this Plan (or any portion thereof) or terminate any outstanding Incentive Award Agreement and the Committee, at any time and from time to time, may amend this Plan or amend or modify the terms of an outstanding Incentive Award. The Committee’s power and authority to amend or modify the terms of an outstanding Incentive Award includes the authority to modify the number of shares or other terms and conditions of an Incentive Award, extend the term of an Incentive Award, accelerate the exercisability or vesting or otherwise terminate any restrictions relating to an Incentive Award, accept the surrender of any outstanding Incentive Award or, to the extent not previously exercised or vested, authorize the grant of new Incentive Awards in substitution for surrendered Incentive Awards; provided , however that the amended or modified terms are permitted by this Plan as then in effect and that any Participant adversely affected by such amended or modified terms has consented to such amendment or modification.

21.2 Stockholder Approval . No amendments to this Plan will be effective without approval of the Company’s stockholders if stockholder approval of the amendment is then required pursuant to Section 422 of the Code, the rules of the primary stock exchange or stock market on which the Common Stock is then traded, applicable U.S. state corporate laws or regulations, applicable U.S. federal laws or regulations, and the applicable laws of any foreign country or jurisdiction where Incentive Awards are, or will be, granted under this Plan.

21.3 Incentive Awards Previously Granted . Notwithstanding any other provision of this Plan to the contrary, no termination, suspension or amendment of this Plan may adversely affect any outstanding Incentive Award without the consent of the affected Participant; provided , however , that this sentence will not impair the right of the Committee to take whatever action it deems appropriate under Sections 3.4, 4.5, 13.5, 15, 17, 20 or 21.4 of this Plan.

32

21.4 Amendments to Conform to Law . Notwithstanding any other provision of this Plan to the contrary, the Committee may amend this Plan or an Incentive Award Agreement, to take effect retroactively or otherwise, as deemed necessary or advisable for the purpose of conforming this Plan or an Incentive Award Agreement to any present or future law relating to plans of this or similar nature, and to the administrative regulations and rulings promulgated thereunder. By accepting an Incentive Award under this Plan, a Participant agrees to any amendment made pursuant to this Section 21.4 to any Incentive Award granted under this Plan without further consideration or action.

22. Effective Date and Duration of this Plan .

The Plan is effective as of the Effective Date. The Plan will terminate at midnight on the day before the ten year anniversary of the date the Plan was initially approved by the Board, and may be terminated prior to such time by Board action. No Incentive Award will be granted after termination of this Plan, but Incentive Awards outstanding upon termination of this Plan will remain outstanding in accordance with their applicable terms and conditions and the terms and conditions of this Plan.

2. Definitions . For purposes of the Plan, the following terms shall be defined as set forth below:

(c) “ Common Stock ” shall mean shares of common stock, par value $0.001 of the Company or the stock or other securities into which such Common Stock may be changed in accordance with Section 13 of the Plan.

(d) “ Company Group ” shall mean the Company, together with each Designated Subsidiary.

(e) “ Compensation ” shall mean regular straight-time earnings and commissions that are included in regular compensation, including amounts that would have constituted compensation but for a Participant’s election to defer or reduce compensation pursuant to any deferred compensation, cafeteria, capital accumulation or any other similar plan of the Company and including overtime and shift premium, but excluding all other amounts such as amounts attributable to stock-based, cash-based and other incentive compensation and bonuses (except to the extent that the inclusion of any such item is specifically directed by the Committee), determined in a manner consistent with the requirements of Section 423 of the Code.

(f) “ Designated Subsidiary ” shall mean a Subsidiary that has been designated by the Board from time to time, in its sole discretion, as eligible to participate in the Plan.

(b) No Eligible Employee shall be granted an Option under the Plan if the amount of payroll deductions that the Eligible Employee has elected to have withheld under such Option (pursuant to Section 5 below) would permit the Eligible Employee to purchase Shares under all “employee stock purchase plans” (within the meaning of Section 423 of the Code) of the Company or any Subsidiary to accrue ( i.e. , become exercisable) at a rate that exceeds twenty five thousand dollars (USD $25,000) of Fair Market Value of such Shares (determined as of the Enrollment Date) for each calendar year in which such Option is outstanding at any time.

4. Offering Periods . Options to purchase Shares shall be offered to Participants under the Plan through a continuous series of Offerings, each continuing for six months and each of which shall commence on January 1 and July 1 of each year, as the case may be, and shall terminate on June 30 and December 31 of such year, as the case may be (each such period being, an “ Offering Period ”);  provided ,  however , that (a) the Committee may suspend Offerings under the Plan or any Offering Period at any time and for any reason and (b) the first Offering Period under the Plan and any subsequent Offering Period commenced immediately after a suspension of the Plan shall have an Enrollment Date and Exercise Date as determined by the Committee in its sole discretion. Offerings under the Plan shall continue until either (i) the Committee decides, in its sole discretion, (x) to suspend Offerings under the Plan or (y) that no further Offerings shall be made because the number of Shares remaining available under the Plan is insufficient to make an Offering to all Eligible Employees, or (ii) the Plan is terminated under Section 20 below. Notwithstanding the foregoing, and without limiting the authority of the Committee under Sections 14, 19 and 20 of the Plan, the Committee, in its sole discretion, may (a) accelerate the Exercise Date of the then current Offering Period and provide for the exercise of Options thereunder by Participants in accordance with Section 8 of the Plan, or (b) accelerate the Exercise Date of the then current Offering Period and provide that all payroll deductions credited to the accounts of Participants will be paid to Participants as soon as practicable after such Exercise Date and that all Options for such Offering Period will automatically be canceled and will no longer be exercisable, if such change is announced at least five (5) days prior to the newly scheduled Exercise Date.

5. Participation .

(a) Each Eligible Employee may become a Participant with respect to any Offering Period by completing a subscription agreement authorizing payroll deductions in a form acceptable to the Committee and filing it with the Company (or its designated third-party stock plan administrator) at least fifteen (15) calendar days (or a different number of days as may be determined by the Committee, in its sole discretion) prior to the first day of such Offering Period. A Participant’s completion of a subscription agreement with respect to any Offering Period will enroll such Participant in the Plan for each subsequent Offering Period on the terms contained therein until the Participant either submits a new subscription agreement, withdraws from participation under the Plan as provided in Section 10 of the Plan, or otherwise becomes ineligible to participate in the Plan.

(d) The subscription agreement(s) used in connection with the Plan shall be in a form prescribed by the Committee, and the Committee may, in its sole discretion, determine whether such agreement shall be submitted in written or electronic form.

6. Payroll Deductions .

(a) At the time a Participant files a subscription agreement, such Participant shall elect to have payroll deductions made on each payday (such amount to be deducted after any applicable deduction for tax and other withholding) during the Offering Period in an amount from one percent (1%) to twenty percent (20%) of the Compensation which the Participant receives on each pay day during the Offering Period.

(b) All payroll deductions made for a Participant shall be credited to his or her account under the Plan and shall be withheld in whole percentages only. Except as described in Section 5(c) of the Plan, a Participant may not make any additional payments into such account.

(c) A Participant may discontinue his or her participation in the Plan as provided in Section 10 of the Plan. A Participant may not increase or decrease the rate of his or her payroll deductions during the Offering Period.

(d) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) of the Plan, a Participant’s payroll deductions may be decreased to zero percent (0%) at any time during an Offering Period.

5

(e) At the time an Option is exercised, in whole or in part, or at the time some or all of the Shares issued under the Plan are disposed of, the Participant must make adequate provision for any foreign, federal, state, or other tax obligations, if any, which arise upon the exercise of the Option or the disposition of the Shares. At any time, the Company may, but shall not be obligated to, withhold from all of the Participant’s compensation the amount necessary for the Company to meet applicable withholding obligations, including any withholding required to make available to the Company any tax deductions or benefits attributable to the sale or early disposition of Shares by the Participant.

7. Grant of Option . On the Enrollment Date of each Offering Period, each Participant in such Offering Period shall be granted an Option to purchase on the Exercise Date with respect to such Offering Period (at the applicable Purchase Price) up to a number of the Shares determined by dividing such Participant’s payroll deductions accumulated prior to such Exercise Date and retained in the Participant’s account as of the Exercise Date by the applicable Purchase Price; provided, however, that (i) such purchase shall be subject to the limitations set forth in Sections 3 and 13 of the Plan, and (ii) in no event may more than [one thousand (1,000)] Shares be purchased by any Participant during any Offering Period. Exercise of the Option shall occur as provided in Section 8 of the Plan, unless the Participant has withdrawn from participation pursuant to Section 10 of the Plan or otherwise becomes ineligible to participate in the Plan. The Option shall expire on the last day of the Offering Period.

8. Exercise of Option .

(a) Unless a Participant withdraws from the Plan as provided in Section 10 of the Plan or otherwise becomes ineligible to participate in the Plan, such Participant’s Option for the purchase of Shares shall be exercised automatically on the Exercise Date, and the maximum number of full Shares subject to the Option shall be purchased for such Participant at the applicable Purchase Price with the accumulated payroll deductions in his account. No fractional Shares shall be purchased, and any payroll deductions accumulated in a Participant’s account which are not sufficient to purchase a full Share shall be retained in such Participant’s account for the subsequent Offering Period. During a Participant’s lifetime, a Participant’s Option to purchase Shares hereunder is exercisable only by such Participant.

(b) If the Committee determines that, on a given Exercise Date, the number of Shares with respect to which Options are to be exercised may exceed (i) the number of Shares that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period (notwithstanding any authorization of additional Shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date); (ii) the number of Shares available for sale under the Plan on such Exercise Date; or (iii) the number of Shares available for sale on such Exercise Date, the Committee shall provide that the Company (or its designated third-party stock plan administrator) shall make a pro rata allocation of the Shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants exercising Options to purchase Shares on such Exercise Date, and shall decide, in its

6

sole discretion, to either (x) continue all Offering Periods then in effect or (y) terminate any or all Offering Periods then in effect pursuant to Section 20 of the Plan. In the event of such a pro rata allocation of Shares pursuant to this Section 8(b), the balance of the amount credited to the account of each Participant that has not been applied to the purchase of Shares shall be paid to each such Participant in one lump sum in cash as soon as reasonably practicable after the Exercise Date, without any interest thereon.

9. Deposit of Shares.  As promptly as practicable after each Exercise Date on which a purchase of Shares occurs, the Company may arrange for the deposit, into each Participant’s account with any broker designated by the Company to administer this Plan, of the number of Shares purchased upon exercise of each such Participant’s Option.

10. Withdrawal .

(a) At any time prior to the Exercise Date, a Participant, by giving written notice to the Company (or its designated third-party stock plan administrator) in a form acceptable to the Committee, may withdraw all but not less than all of the payroll deductions credited to such Participant’s account and not yet used to exercise an Option under the Plan. All of the Participant’s payroll deductions credited to his or her account during the Offering Period, plus any balance retained in his or her account from a prior Offering Period, if any, shall be paid to such Participant as soon as reasonably practicable after receipt of notice of withdrawal, and such Participant’s Option for the Offering Period shall be automatically terminated, and no further payroll deductions for the purchase of Shares shall be made for such Offering Period. If a Participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of any subsequent Offering Period unless the Participant delivers to the Company (or its designated third-party stock plan administrator) a new subscription agreement in accordance with the terms of Section 5(a) of the Plan.

(b) A Participant’s withdrawal from an Offering Period shall not have any effect upon such Participant’s eligibility to participate in any similar plan which may hereafter be adopted by the Company or in Offering Periods which commence after the termination of the Offering Period from which the Participant withdraws.

11. Termination of Employment . Upon a Participant’s ceasing to be an Eligible Employee, for any reason, such Participant shall be deemed to have elected to withdraw from the Plan, and the payroll deductions credited to such Participant’s account during the Offering Period, plus any balance retained in his or her account from a prior Offering Period, if any, shall be paid to the Participant, or in the case of his or her death, to the person or persons entitled thereto under Section 15 of the Plan, as soon as reasonably practicable, and such Participant’s Option for the Offering Period shall be automatically terminated.

(b) Except as otherwise provided herein, with respect to Shares subject to an Option granted under the Plan, a Participant shall not be deemed to be a stockholder of the Company, and the Participant shall not have any of the rights or privileges of a stockholder, until such Shares have been issued to the Participant or his or her nominee following exercise of the Participant’s Option. No adjustments shall be made for dividends (ordinary or extraordinary, whether in cash securities, or other property) or distributions or other rights for which the record date occurs prior to the date of such issuance, except as otherwise expressly provided herein.

14. Administration . The Plan will be administered by the Committee. To the extent consistent with applicable corporate or other law, the Committee may delegate to any officers of the Company the duties, power and authority of the Committee under the Plan pursuant to such conditions or limitations as the Committee may establish;  provided ,  however , that only the Committee may exercise such duties, power and authority with respect to Participants who are subject to Section 16 of the Exchange Act. The Committee may exercise its duties, power and authority under the Plan in its sole discretion without the consent of any Participant or other party, unless the Plan specifically provides otherwise. Each determination, interpretation or other action made or taken by the Committee pursuant to the provisions of the Plan will be final, conclusive and binding for all purposes and on all persons, including, without limitation, the Company, the stockholders of the Company, the Participants and their respective successors-in-interest. No member of the Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Option granted under the Plan.

15. Designation of Beneficiary .

(a) A Participant may file a written designation of a beneficiary who is to receive any Shares and cash, if any, from such Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the Option is exercised but prior to delivery to such Participant of such Shares and cash. In addition, a Participant may file a written designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the Option. To the extent required under applicable law, spousal consent shall be required for such designation to be effective if the Participant is married and the designated beneficiary is not the Participant’s spouse.

8

(b) Such beneficiary designation may be changed by the Participant at any time by written notice to the Company. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such Shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company may, in its discretion, deliver such Shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent, or relative is known to the Company, then to such other person as the Company may designate.

16. Transferability . Neither payroll deductions credited to a Participant’s account nor any rights with regard to the exercise of an Option or to receive Shares under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way by the Participant (other than by will, the laws of descent and distribution, or as provided in Section 15 of the Plan). Any such attempt at assignment, transfer, pledge, or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 of the Plan.

17. Use of Funds . All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions.

(b) Merger, Asset Sale, Dissolution or Liquidation . In the event of a proposed merger of the Company with or into another corporation or a proposed sale of all or substantially all of the assets of the Company, each outstanding Option shall be assumed or an equivalent Option substituted by the successor corporation or a parent or subsidiary of the successor corporation. In the event that the successor corporation or a parent or subsidiary of the successor corporation refuses to assume or substitute for the Option, or in the event of the proposed dissolution, or liquidation of the Company, the Offering Period then in progress shall be shortened by the Committee by setting a new Exercise Date (the “ New Exercise Date ”), which shall occur no later than immediately prior to the effective date of such proposed merger, sale, dissolution or liquidation, as applicable. The Company shall notify each Participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option shall be exercised automatically on the New Exercise Date, unless prior to such New Exercise Date the Participant has withdrawn from the Offering Period as provided in Section 10 of the Plan.

20. Amendment or Termination .

(a) The Board may at any time and for any reason terminate or amend the Plan. Except as provided in Section 19 of the Plan and this Section 20, no amendment or termination of the Plan may make any change in any Option theretofore granted which adversely affects the rights of any Participant without the consent of such Participant; provided, however, that an Offering Period may be terminated by the Board if the Board determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its stockholders. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation, or stock exchange rule), the Company shall obtain stockholder approval of any amendment in such a manner and to such a degree as required.

(b) Without stockholder approval and without regard to whether any Participant’s rights may be considered to have been “adversely affected,” the Committee shall be entitled to change the Offering Periods (but in no event may an Offering Period have a duration in excess of twenty seven (27) months), limit the frequency and/or number of changes in the amount withheld during an Offering Period, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Shares for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Committee determines in its sole discretion advisable which are consistent with the Plan.

(c) Upon termination of the Plan, the balance in each Participant’s account under the Plan shall be refunded as soon as practicable after such termination, without any interest thereon.

10

(i) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price;

(ii) shortening any Offering Period so that the Offering Period ends on a new Exercise Date, including an Offering Period underway at the time of the Committee action; and

24. Equal Rights and Privileges . All Eligible Employees shall have equal rights and privileges under this Plan so that this Plan qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code. Any provision of this Plan that is inconsistent with this requirement to provide equal rights and privileges shall, without further act or amendment by the Company, the Board or the Committee, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code.

25. Code Section 409A . The Options to purchase Shares under the Plan are not intended to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code. However, if at any time the Committee determines that the Options may be subject to Section 409A of the Code, the Committee shall have the right, in its sole discretion, to amend the Plan and any outstanding Options as it may determine is necessary or desirable either to exempt the Options from the application of Section 409A of the Code or to cause the Options to comply with the requirements of Section 409A of the Code.

12

28. Tax Withholding Obligations .

If a Participant becomes subject to taxation in more than one country between the Enrollment Date and the date of any relevant taxable or tax withholding event, as applicable, Company or any Designated Subsidiary may be required to withhold or account for Tax-Related Items in more than one country.

29. Governing Law . Subject to any applicable provisions of federal law (including, without limitation, Section 423(b) of the Code), and except to the extent expressly provided herein or in connection with other matters of corporate governance and authority (all of which shall be governed by the laws of the Company’s jurisdiction of incorporation), the validity, construction, interpretation, administration and effect of the Plan and any rules, regulations, and actions relating to the Plan shall be governed by and construed exclusively in accordance with the laws of the State of Delaware, notwithstanding the conflicts of laws principles of any jurisdictions.
