BCAC shall cause the Exchange Agent pursuant to irrevocable instructions, to pay the Per Share Merger Consideration out of the Exchange Fund in accordance with this Agreement. Except as contemplated by Section 3.02(c), the Exchange Fund shall not be used for any other purpose.

No dividends or other distributions declared or made after the Effective Time with respect to the BCAC Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of BCAC Common Stock represented thereby until the holder of such Certificate shall surrender such Certificate in accordance with Section 3.02(b).

(d) No Further Rights in Company Capital Stock. The Per Share Merger Consideration payable upon conversion of the Company Capital Stock in accordance with the terms hereof shall be deemed to have been paid and issued in full satisfaction of all rights pertaining to such Company Capital Stock.

(e) Adjustments to Per Share Consideration. The Per Share Merger Consideration shall be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to BCAC Common Stock occurring on or after the date hereof and prior to the Effective Time.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Company Capital Stock for two (2) years after the Effective Time shall be delivered to BCAC, upon demand, and any holders of Company Capital Stock who have not theretofore complied with this Section 3.02 shall thereafter look only to BCAC for the Per Share Merger Consideration. Any portion of the Exchange Fund remaining unclaimed by holders of Company Capital Stock as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable law, become the property of BCAC free and clear of any claims or interest of any person previously entitled thereto.

(g) No Liability. None of the Exchange Agent, BCAC or the Surviving Corporation shall be liable to any holder of Company Capital Stock for any such Company Capital Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law in accordance with Section 3.02.

To the extent that amounts are so withheld and timely remitted to the appropriate Governmental Authority by the Surviving Corporation or BCAC, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by the Surviving Corporation or BCAC, as the case may be.

(i) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed (but in any case to not require the delivery of a bond), the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the Per Share Merger Consideration that such holder is otherwise entitled to receive pursuant to, and in accordance with, the provisions of Section 3.01(a).

Section 3.03 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Company Capital Stock thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates representing Company Capital Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Company Capital Stock, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent or BCAC for any reason shall be converted into the Per Share Merger Consideration in accordance with the provisions of Section 3.01(a).

(“Ladenburg”) and Brookline Capital Markets, no broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the Transactions based upon arrangements made by or on behalf of BCAC or Merger Sub. BCAC has made available to the Company a true and complete copy of all contracts, agreements and arrangements, including its engagement letters, between BCAC, on the one hand, and Ladenburg or Brookline Capital Markets, on the other hand.

Section 5.13 BCAC Trust Fund. As of the date of this Agreement, BCAC has no less than $57,500,000 in the trust fund established by BCAC for the benefit of its public stockholders (the “Trust Fund”) maintained in a trust account at J.P. Morgan Chase Bank, N.A. (the “Trust Account”). The monies of such Trust Account are invested in United States Government securities or money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended, and held in trust by Continental Stock Transfer & Trust Company (the “Trustee”) pursuant to the Investment Management Trust Agreement, dated as of January 28, 2021, between BCAC and the Trustee (the “Trust Agreement”). The Trust Agreement has not been amended or modified and is valid and in full force and effect and is enforceable in accordance with its terms, subject to the Remedies Exceptions. BCAC has complied in all material respects with the terms of the Trust Agreement and is not in breach thereof or default thereunder and there does not exist any event which, with the giving of notice or the lapse of time, would constitute such a breach or default by BCAC or the Trustee. There are no separate contracts, agreements, side letters or other understandings (whether written or unwritten, express or implied): (i) between BCAC and the Trustee that would cause the description of the Trust Agreement in the BCAC SEC Reports to be inaccurate in any material respect; or (ii) that would entitle any person (other than stockholders of BCAC who shall have elected to redeem their shares of BCAC Common Stock pursuant to the BCAC Organizational Documents) to any portion of the proceeds in the Trust Account. Prior to the Closing, none of the funds held in the Trust Account may be released except: (A) to pay income and franchise taxes from any interest income earned in the Trust Account; and (B) upon the exercise of Redemption Rights in accordance with the provisions of the BCAC Organizational Documents. As of the date hereof, there are no Actions pending or, to the knowledge of BCAC, threatened in writing with respect to the Trust Account. As of and following the Effective Time, no stockholder of BCAC shall be entitled to receive any amount from the Trust Account except to the extent such stockholder properly exercised Redemption Rights. Upon consummation of the Merger and notice thereof to the Trustee pursuant to the Trust Agreement, BCAC shall cause the Trustee to, and the Trustee shall thereupon be obligated to, release to BCAC as promptly as practicable, the Trust Funds in accordance with the Trust Agreement at which point the Trust Account shall terminate; provided, however that the liabilities and obligations of BCAC due and owing or incurred at or prior to the Effective Time shall be paid as and when due, including all amounts payable (a) to stockholders of BCAC who shall have exercised their Redemption Rights, (b) with respect to filings, applications and/or other actions taken pursuant to this Agreement required under Law, (c) to the Trustee for fees and costs incurred in accordance with the Trust Agreement; and (d) to third parties (e.g., professionals, printers, etc.) who have rendered services to BCAC in connection with its efforts to effect the Merger (including deferred fees owed by BCAC to Ladenburg, pursuant to that certain Underwriting Agreement, dated January 28, 2021, among Ladenburg and BCAC). As of the date hereof, assuming the accuracy of the representations and warranties of the Company herein and the compliance by the Company with its respective obligations hereunder, BCAC has no reason to believe that any of the conditions to the use of funds in the Trust Account will not be satisfied or funds available in the Trust Account will not be available to BCAC at the Effective Time.

Section 5.14 Employees. Other than any officers as described in the BCAC SEC Reports, BCAC and Merger Sub have never employed any employees or retained any contractors. Other than reimbursement of any out-of-pocket expenses incurred by BCAC’s officers and directors in connection with activities on BCAC’s behalf in an aggregate amount not in excess of the amount of cash held by BCAC outside of the Trust Account, BCAC has no unsatisfied material liability with respect to any employee, officer or director. Except for the Equity Plan and the ESPP, BCAC and Merger Sub have never and do not currently maintain, sponsor, contribute to or have any direct liability under any Parent Plan. “Parent Plan” means any employee benefit plan (as defined in Section 3(3) of ERISA), nonqualified deferred compensation plan subject to Section 409A of the Code, bonus, stock option, stock purchase, restricted stock, incentive, deferred compensation, retiree medical or life insurance, supplemental retirement, severance, change in control, fringe benefit, sick pay and vacation plans or arrangements or other employee benefit or compensation plans, programs or arrangements. The Merger shall not be the direct or indirect cause of any amount paid or payable by BCAC, Merger Sub, or any of their affiliates being classified as an “excess parachute payment” under Section 280G of the Code or the imposition of any additional Tax under Section 4999 or 409A(a)(1)(B) of the Code. There is no contract, agreement, plan or arrangement to which BCAC, Merger Sub, or any of their respective affiliates is a party which provides for the gross-up of any Taxes, including any Taxes imposed by Section 4999 or 409A of the Code.

Section 5.15 Taxes.

(c) None of BCAC or Merger Sub will be required to include any material item of income in, or exclude any material item of deduction from, taxable income for any taxable period (or portion thereof) ending after the Closing Date as a result of any: (i) change in method of accounting for a taxable period ending on or prior to the Closing Date under Section 481(c) of the Code (or any corresponding or similar provision of state, local or foreign income Tax law); (ii) “closing agreement” as described in Section 7121 of the Code (or any corresponding or similar provision of state, local or foreign income Tax law) executed on or prior to the Closing Date; (iii) installment sale or open transaction made on or prior to the Closing Date; (iv) intercompany transaction or any excess loss account described in Treasury Regulations under Code Section 1502 (or any corresponding or similar provision of state, local or foreign income Tax law) entered into or created on or prior to the Closing Date; or (v) prepaid amount received on or prior to the Closing Date outside the ordinary course of business.

(d) Neither BCAC nor Merger Sub has been a member of an affiliated group filing a consolidated, combined or unitary U.S. federal, state, local or foreign income Tax Return (other than a group of which BCAC was the ultimate parent corporation).

(e) Neither BCAC nor Merger Sub has any liability for the Taxes of any person (other than BCAC and Merger Sub) under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign law), as a transferee or successor, by contract (other than an agreement, contract, arrangement or commitment entered into in the ordinary course of business and the primary purpose of which does not relate to Taxes), or otherwise.

(f) Neither BCAC nor Merger Sub (i) has any written request for a ruling in respect of Taxes pending between BCAC and/or Merger Sub, on the one hand, and any Tax authority, on the other hand, or; (ii) has entered into any closing agreement, private letter ruling technical advice memoranda or similar agreements with any Tax authority.

(g) Neither BCAC nor Merger Sub has in the past three (3) years distributed stock of another person, or has had its stock distributed by another person, in a transaction that was purported or intended to be governed in whole or in part by Section 355 or Section 361 of the Code.

(h) Neither BCAC nor Merger Sub has engaged in or entered into a “listed transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(2).

(i) Neither BCAC nor Merger Sub has taken any action (nor permitted any action to be taken), or is aware of any fact or circumstance, that would reasonably be expected to prevent, impair or impede the Transactions from qualifying for the Intended Tax Treatment, as described in Section 7.11.

Section 5.16 Listing. The issued and outstanding BCAC Units are registered pursuant to Section 12(b) of the Exchange Act and are listed for trading on the Stock Exchange under the symbol “BCACU”. The issued and outstanding shares of BCAC Common Stock are registered pursuant to Section 12(b) of the Exchange Act and are listed for trading on the Stock Exchange under the symbol “BCAC”. The issued and outstanding BCAC Warrants are registered pursuant to Section 12(b) of the Exchange Act and are listed for trading on the Stock Exchange under the symbol “BCACW”. As of the date of this Agreement, there is no Action pending or, to the knowledge of BCAC, threatened in writing against BCAC by the Stock Exchange or the SEC with respect to any intention by such entity to deregister the BCAC Units, the shares of BCAC Common Stock or BCAC Warrants or terminate the listing of BCAC on the Stock Exchange. None of BCAC or any of its affiliates has taken any action in an attempt to terminate the registration of the BCAC Units, the shares of BCAC Common Stock or the BCAC Warrants under the Exchange Act.

Section 5.17 Private Placements. BCAC has made available to the Company true, correct and complete copies of the Subscription Agreements. The Subscription Agreements (a) are in full force and effect without amendment or modification, (b) are the valid, binding and enforceable obligations of BCAC and, to the knowledge of BCAC, each other party thereto (other than the Company and except, in any case, as may be limited by Remedies Exception) and (c) have not been withdrawn, terminated or rescinded in any respect. There are no contracts or agreements between BCAC and any other party to a Subscription Agreement relating to any Subscription Agreement that would reasonably be expected to affect the obligations of the such investors to contribute to BCAC the applicable portion of the Private Placements set forth in the Subscription Agreements, and, to the knowledge of BCAC, no facts or circumstances exist that may reasonably be expected to result in any of the conditions set forth in any Subscription Agreement not being satisfied, or the Private Placements not being available to BCAC, on the Closing Date. No event has occurred that, with or without notice, lapse of time or both, would constitute a default or breach on the part of BCAC under any material term or condition of any Subscription Agreement and, as of the date hereof, BCAC has no reason to believe that it will be unable to satisfy in all material respects on a timely basis any term or condition of Closing to be satisfied by it contained in any Subscription Agreement. The Subscription Agreements contain all of the conditions precedent (other than the conditions contained in this Agreement or the Transaction Documents) to the obligations of the parties thereto to contribute to BCAC the applicable portion of the Private Placements set forth in the Subscription Agreements on the terms therein.

Section 5.18 BCAC’s and Merger Sub’s Investigation and Reliance.

Neither BCAC nor Merger Sub is relying on any statement, representation or warranty, oral or written, express or implied, made by the Company or any of its Representatives, except as expressly set forth in Article IV (as modified by the Company Disclosure Schedule). Neither the Company nor any of its respective stockholders, affiliates or Representatives shall have any liability to BCAC, Merger Sub or any of their respective stockholders, affiliates or Representatives resulting from the use of any information, documents or materials made available to BCAC or Merger Sub or any of their Representatives, whether orally or in writing, in any confidential information memoranda, “data rooms,” management presentations, due diligence discussions or in any other form in expectation of the Transactions.

Section 7.05 Exclusivity.

(a) From the date of this Agreement and ending on the earlier of (i) the Closing and (ii) the termination of this Agreement, the Company shall not, and shall direct its Representatives not to, directly or indirectly, (A) solicit, negotiate with, provide any nonpublic information regarding the Company’s business, or enter into any Contract with, or in any manner knowingly encourage, any proposal of, any person (other than BCAC and its affiliates) relating to a potential acquisition of all or substantially all of the equity interests or assets of the Company, whether by merger, sale of stock, sale of assets, business combination or otherwise (an “Alternative Transaction”), (B) enter into any agreement regarding, continue or otherwise participate in any discussions regarding, or furnish to any person any information with respect to, or cooperate in any way that would otherwise reasonably be expected to lead to, any Alternative Transaction or (C) commence, continue or renew any due diligence investigation regarding any Alternative Transaction; provided, that the execution, delivery and performance of this Agreement and the Transaction Documents and the consummation of the Transactions shall not be deemed a violation of this Section 7.05(a). The Company shall, and shall direct its Representatives to, immediately cease any and all existing discussions or negotiations with any person conducted heretofore with respect to any Alternative Transaction. The Company also agrees that it will promptly request each person (other than the parties hereto and their respective Representatives) that has prior to the date hereof executed a confidentiality agreement in connection with its, his or her consideration of acquiring the Company to return or destroy all Confidential Information furnished to such person by or on behalf of it, him or her prior to the date hereof.

Without limiting the foregoing, the parties agree that any violation of the restrictions set forth in this Section 7.05(a) by the Company or its Representatives shall be deemed to be a breach of this Section 7.05(a) by the Company. For clarity, the Company may inform any person making an unsolicited proposal regarding an Alternative Transaction of the terms of this Section 7.05.

(b) From and after the date hereof until the Effective Time or, if earlier, the termination of this Agreement, BCAC shall not take, nor shall it permit any of its affiliates or Representatives to take, whether directly or indirectly, any action to solicit, initiate, continue or engage in discussions or negotiations with, or enter into any agreement with, or encourage, respond, provide information to or commence due diligence with respect to, any person (other than the Company, its stockholders and/or any of their affiliates or Representatives), concerning, relating to or which is intended or is reasonably likely to give rise to or result in, any offer, inquiry, proposal or indication of interest, written or oral relating to any business combination transaction

(a “Business Combination Proposal”) other than with the Company, its stockholders and their respective affiliates and Representatives. BCAC shall, and shall cause its affiliates and Representatives to, immediately cease any and all existing discussions or negotiations with any person (other than with the Company, its stockholders and their respective affiliates and Representatives) conducted prior to the date hereof with respect to, or which is reasonably likely to give rise to or result in, a Business Combination Proposal.

Subject to approval of the ESPP by BCAC’s stockholders, following the Effective Time, BCAC shall file an effective Form S-8 Registration Statement with the SEC with respect to the shares of BCAC Common Stock issuable under the ESPP and shall use commercially reasonable efforts to maintain the effectiveness of such Form S-8 Registration Statement for so long as awards granted pursuant to the ESPP remain outstanding.

In addition, BCAC shall use commercially reasonable efforts to (i) cause to be waived any eligibility waiting periods, any evidence of insurability requirements and the application of any pre-existing condition limitations under each of the employee benefit plans established or maintained by the Surviving Corporation or any of its subsidiaries that cover the Continuing Employees or their dependents, and (ii) cause any eligible expenses incurred by any Continuing Employee and his or her covered dependents, during the portion of the plan year in which the Closing occurs, under those health and welfare benefit plans in which such Continuing Employee currently participates to be taken into account under those health and welfare benefit plans in which such Continuing Employee participates subsequent to the Closing Date for purposes of satisfying all deductible, coinsurance, and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year. Following the Closing, Surviving Corporation will honor all accrued but unused vacation and other paid time off of the Continuing Employees that existed immediately prior to the Closing.

On and after the Closing Date, for a period of no less than six (6) years, BCAC shall, with regard to pre-Closing acts, errors, omissions of BCAC directors and officers, maintain a certificate of incorporation and bylaws with provisions no less favorable with respect to indemnification, advancement, expense reimbursement, and exculpation, than are set forth in the certificate of incorporation or bylaws of BCAC just prior to Closing.

(b) On the Closing Date, each of the Company and BCAC shall either (x) obtain a non-cancelable run-off directors and officers “tail” insurance policy providing coverage that, taken as a whole, is no less favorable than under such person’s policy as in effect on the date of this Agreement or (y) otherwise provide coverage that, taken as a whole, is at least as favorable than such person’s policy as in effect on the date of this Agreement, in either case, for a period of six (6) years after the Closing Date, to provide insurance coverage for events, acts or omissions occurring on or prior to the Closing Date for all persons who were directors or officers of the Company or BCAC, as applicable, on or prior to the Closing Date.

(d) On the Closing Date, BCAC shall enter into customary indemnification agreements reasonably satisfactory to the Company with the post-Closing directors and officers of BCAC and the Surviving Corporation, which indemnification agreements shall continue to be effective following the Closing.

(e) On and after the Closing Date, for a period of six (6) years after the Closing Date, BCAC agrees that it shall defend, indemnify and hold harmless the Sponsor, its affiliates, and their respective present and former directors and officers against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any Action by any stockholder of BCAC who has not exercised Redemption Rights arising from Sponsor’s ownership of equity securities of BCAC, or its control

None of the representations, warranties, covenants, obligations or other agreements in this Agreement or in any certificate, statement or instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such representations, warranties, covenants, obligations, agreements and other provisions, shall survive the Closing and all such representations, warranties, covenants, obligations or other agreements shall terminate and expire upon the occurrence of the Closing (and there shall be no liability after the Closing in respect thereof), except for (a) those covenants and agreements contained herein that by their terms expressly apply in whole or in part after the Closing and then only with respect to any breaches occurring after the Closing and (b) this Article X and any corresponding definitions set forth in Article I.

Section 10.03 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

Section 10.04 Entire Agreement; Assignment. This Agreement and the Ancillary Agreements constitute the entire agreement among the parties with respect to the subject matter hereof and supersede, except as set forth in Section 7.04(b), all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, except for the Confidentiality Agreement. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise) by any party without the prior express written consent of the other parties hereto.

Section 10.05 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 7.07 (which is intended to be for the benefit of the persons covered thereby and may be enforced by such persons).

Section 10.06 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to any conflict of law rule or principle that would result in the application of any laws other than the laws of the State of Delaware. All legal actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in the Delaware Chancery Court; provided, however, that if jurisdiction is not then available in the Delaware Chancery Court, then any such legal Action may be brought in any federal court located in the State of Delaware or any other Delaware state court. The parties hereto hereby (a) irrevocably submit to the exclusive jurisdiction of the aforesaid courts for themselves and with respect to their respective properties for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (b) agree not to commence any Action relating thereto except in the courts described above in Delaware, other than Actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Action arising out of or relating to this Agreement or the Transactions, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the Action in any such court is brought in an inconvenient forum, (ii) the venue of such Action is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.07.

Section 10.08 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 10.09 Counterparts. This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 10.10 Specific Performance. The parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof, and, accordingly, that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger) in the Court of Chancery of the State of Delaware or, if that court does not have jurisdiction, any court of the United States located in the State of Delaware without proof of actual damages or otherwise, in addition to any other remedy to which they are entitled at law or in equity as expressly permitted in this Agreement.

The total number of shares of stock that the Corporation shall have authority to issue is 1,020,000,000 shares, of which 1,000,000,000 shares are Common Stock, $0.001 par value, and 20,000,000 shares are Preferred Stock, $0.001 par value.

Section 2. Each share of Common Stock shall entitle the holder thereof to one (1) vote on any matter submitted to a vote at a meeting of stockholders.

Section 3. The Preferred Stock may be issued from time to time in one or more series pursuant to a resolution or resolutions providing for such issue duly adopted by the Board of Directors (authority to do so being hereby expressly vested in the Board of Directors). The Board of Directors is further authorized, subject to limitations prescribed by law, to fix by resolution or resolutions the designations, powers, preferences and rights, and the qualifications, limitations or restrictions thereof, of any wholly unissued series of Preferred Stock, including, without limitation, authority to fix by resolution or resolutions the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and liquidation preferences of any such series, and the number of shares constituting any such series and the designation thereof, or any of the foregoing. The Board of Directors is further authorized to increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares of any such series then outstanding) the number of shares of any series, the number of which was fixed by it, subsequent to the issuance of shares of such series then outstanding, subject to the powers, preferences and rights, and the qualifications, limitations and restrictions thereof stated in this Amended and Restated Certificate of Incorporation or the resolution of the Board of Directors originally fixing the number of shares of such series.

ARTICLE V

Section 1. The number of directors that constitutes the entire Board of Directors of the Corporation shall be determined in the manner set forth in the Bylaws of the Corporation. At each annual meeting of stockholders, directors of the Corporation shall be elected to hold office until the expiration of the term for which they are elected and until their successors have been duly elected and qualified or until their earlier resignation or removal; except that if any such meeting shall not be so held, such election shall take place at a stockholders’ meeting called and held in accordance with the DGCL.

Section 2. From and after the effectiveness of this Amended and Restated Certificate of Incorporation, the directors of the Corporation (other than any who may be elected by holders of Preferred Stock under specified circumstances) shall be divided into three classes as nearly equal in size as is practicable, hereby designated Class I, Class II and Class III. Directors already in office shall be assigned to each class at the time such classification becomes effective in accordance with a resolution or resolutions adopted by the Board of Directors. At the first annual meeting of stockholders following the date hereof, the term of office of the Class I directors shall expire and

Class I directors shall be elected for a full term of three years. At the second annual meeting of stockholders following the date hereof, the term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the third annual meeting of stockholders following the date hereof, the term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting. If the number of directors is changed, any newly created directorships or decrease in directorships shall be so apportioned hereafter among the classes as to make all classes as nearly equal in number as is practicable, provided that no decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

ARTICLE VI

Section 1. Any director or the entire Board of Directors may be removed from office at any time, but only for cause, and only by the affirmative vote of the holders of at least a majority of the voting power of the issued and outstanding capital stock of the Corporation entitled to vote in the election of directors.

Section 2. Except as otherwise provided for or fixed by or pursuant to the provisions of Article IV hereof in relation to the rights of the holders of Preferred Stock to elect directors under specified circumstances, newly created directorships resulting from any increase in the number of directors, created in accordance with the Bylaws of the Corporation, and any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other cause shall be filled only by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors, or by a sole remaining director, and not by the stockholders. A person so elected by the Board of Directors to fill a vacancy or newly created directorship shall hold office until the next election of the class for which such director shall have been chosen until his or her successor shall have been duly elected and qualified, or until such director’s earlier death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

ARTICLE VII

Section 1. The Corporation is to have perpetual existence.

Section 2. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

Section 3. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to adopt, alter, amend or repeal the Bylaws of the Corporation. The affirmative vote of at least a majority of the Board of Directors then in office shall be required in order for the Board of Directors to adopt, amend, alter or repeal the Corporation’s Bylaws. The Corporation’s Bylaws may also be adopted, amended, altered or repealed by the stockholders of the Corporation.

Further, if the stockholders

of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in substantially the same proportions as their ownership of shares of the Company’s voting stock immediately prior to the change in ownership, direct or indirect beneficial ownership of 50% or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event will not be considered a Change in Control under this subsection (a).

3.4 Share Reserve. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of this Plan.

4. Administration of this Plan.

4.1 Procedure.

4.1.1 Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer this Plan.

4.1.2 Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3.

4.1.3 Other Administration. Other than as provided above, this Plan will be administered by (A) the Board or (B) a Committee, which Committee will be constituted to comply with Applicable Laws.

4.2 Powers of the Administrator. Subject to the provisions of this Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion:

(a) to determine the Fair Market Value;

-7-

(b) to select the Service Providers to whom Awards may be granted hereunder;

(d) to approve forms of Award Agreements for use under this Plan;

(e) to determine the terms and conditions, not inconsistent with the terms of this Plan, of any Award granted hereunder. Such terms and conditions include the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the Shares relating thereto (including temporarily suspending the exercisability of an Award if the Administrator deems such suspension to be necessary or appropriate for administrative purposes or to comply with Applicable Laws, provided that such suspension must be lifted prior to the expiration of the maximum term and post-termination exercisability period of an Award), based in each case on such factors as the Administrator will determine;

(f) to institute and determine the terms and conditions of an Exchange Program, including, subject to Section 20.3, to unilaterally implement an Exchange Program without the consent of the applicable Award holder;

(g) to construe and interpret the terms of this Plan and Awards granted pursuant to this Plan;

(h) to prescribe, amend and rescind rules and regulations relating to this Plan, including rules and regulations relating to sub-plans established for the purpose of facilitating compliance with applicable non-U.S. laws, easing the administration of this Plan or for qualifying for favorable tax treatment under applicable non-U.S. laws, in each case as the Administrator may deem necessary or advisable;

(i) to modify or amend each Award (subject to Section 20.3), including the discretionary authority to extend the post-termination exercisability period of Awards and to extend the maximum term of an Option or Stock Appreciation Right (subject to Sections 6.4 and 7.5);

(j) to allow Participants to satisfy withholding tax obligations in a manner prescribed in Section 16;

(k) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator;

(l) to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that otherwise would be due to such Participant under an Award; and

(m) to make all other determinations deemed necessary or advisable for administering this Plan.

-8-

4.3 Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards and will be given the maximum deference permitted by Applicable Laws.

5. Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, or Performance Awards may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

6. Stock Options.

6.1 Grant of Options. Subject to the terms and provisions of this Plan, the Administrator, at any time and from time to time, may grant Options to Service Providers in such amounts as the Administrator, in its sole discretion, will determine.

6.2 Option Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the exercise price, the term of the Option, the number of Shares subject to the Option, the exercise restrictions, if any, applicable to the Option, and such other terms and conditions as the Administrator, in its sole discretion, will determine.

6.3 Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. Notwithstanding such designation, however, to the extent that the aggregate fair market value of the shares with respect to which incentive stock options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such options will be treated as nonstatutory stock options. For purposes of this Section 6.3, incentive stock options will be taken into account in the order in which they were granted, the fair market value of the shares will be determined as of the time the option with respect to such shares is granted, and calculation will be performed in accordance with Code Section 422 and the U.S. Treasury Regulations promulgated thereunder.

6.4 Term of Option. The term of each Option will be stated in the Award Agreement; provided, however, that the term will be no more than 10 years from the date of grant thereof. In the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the term of the Incentive Stock Option will be 5 years from the date of grant or such shorter term as may be provided in the Award Agreement.

6.5 Option Exercise Price and Consideration.

6.5.1 Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option will be determined by the Administrator, but will be no less than 100% of the Fair Market Value per Share on the date of grant. In addition, in the case of an Incentive Stock Option granted to an Employee who owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the per Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing provisions of this Section 6.5.1, Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Code Section 424(a).

-9-

6.5.2 Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised.

6.5.3 Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (a) cash (including cash equivalents); (b) check; (c) promissory note, to the extent permitted by Applicable Laws, (d) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided further that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (e) consideration received by the Company under a cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with this Plan; (f) by net exercise; (g) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws, or (h) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator will consider if acceptance of such consideration may be reasonably expected to benefit the Company.

6.6 Exercise of Option.

6.6.1 Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of this Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share.

An Option will be deemed exercised when the Company receives: (a) notice of exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option, and (b) full payment for the Shares with respect to which the Option is exercised (together with applicable tax withholdings). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and this Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 15.

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of this Plan and for sale under the Option, by the number of Shares as to which the Option is exercised.

-10-

6.6.2 Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon such cessation as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within 3 months of such cessation, or such shorter or longer period of time, as is specified in the Award Agreement, in no event later than the expiration of the term of such Option as set forth in the Award Agreement or Section 6.4. Unless otherwise provided by the Administrator or set forth in the Award Agreement or other written agreement authorized by the Administrator between the Participant and the Company or any of its Subsidiaries or Parents, as applicable, if on such date of cessation the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to this Plan immediately. If after such cessation the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to this Plan.

6.6.3 Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within 6 months of cessation, or such longer or shorter period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement or Section 6.4, as applicable) to the extent the Option is vested on such date of cessation. Unless otherwise provided by the Administrator or set forth in the Award Agreement or other written agreement authorized by the Administrator between the Participant and the Company or any of its Subsidiaries or Parents, as applicable, if on the date of cessation the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to this Plan immediately. If after such cessation the Participant does not exercise his or her Option within the time specified in this Plan, the Option will terminate, and the Shares covered by such Option will revert to this Plan.

6.6.4 Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised within 6 months following the Participant’s death, or within such longer or shorter period of time as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement or Section 6.4, as applicable), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to the Participant’s death in a form (if any) acceptable to the Administrator. If the Administrator has not permitted the designation of a beneficiary or if no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution (each, a “Legal Representative”). If the Option is exercised pursuant to this Section 6.6.4, Participant’s designated beneficiary or Legal Representative shall be subject to the terms of this Plan and the Award Agreement, including the restrictions on transferability and forfeitability applicable to the Service Provider. Unless otherwise provided by the Administrator or set forth in the Award Agreement or other written agreement authorized by the Administrator between the Participant and the Company or any of its Subsidiaries or Parents, as applicable, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to this Plan immediately. If the Option is not so exercised within the time specified in this Plan, the Option will terminate, and the Shares covered by such Option will revert to this Plan.

-11-

6.6.5 Tolling Expiration. A Participant’s Award Agreement may also provide that:

(a) if the exercise of the Option following the cessation of Participant’s status as a Service Provider (other than upon the Participant’s death or Disability) would result in liability under Section 16(b) of the Exchange Act, then the Option will terminate on the earlier of (i) the expiration of the term of the Option set forth in the Award Agreement, or (ii) the 10^th day after the last date on which such exercise would result in liability under Section 16(b) of the Exchange Act; or

(b) if the exercise of the Option following the cessation of the Participant’s status as a Service Provider (other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of Shares would violate the registration requirements under the Securities Act, then the Option will terminate on the earlier of (i) the expiration of the term of the Option or (ii) the expiration of a period of 30 days after the cessation of the Participant’s status as a Service Provider during which the exercise of the Option would not be in violation of such registration requirements.

7.3 Exercise Price and Other Terms. The per Share exercise price for the Shares that will determine the amount of the payment to be received upon exercise of a Stock Appreciation Right as set forth in Section 7.6 will be determined by the Administrator and will be no less than 100% of the Fair Market Value per Share on the date of grant. Otherwise, the Administrator, subject to the provisions of this Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under this Plan.

7.4 Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine.

A Stock Appreciation Right granted under this Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6.4 relating to the maximum term and Section 6.6 relating to exercise also will apply to Stock Appreciation Rights.

7.6 Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying:

-12-

(a) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

(b) The number of Shares with respect to which the Stock Appreciation Right is exercised.

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or in some combination thereof.

8. Restricted Stock.

8.2 Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction (if any), the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of Restricted Stock until the restrictions on such Shares have lapsed. The Administrator, in its sole discretion, may determine that an Award of Restricted Stock will not be subject to any Period of Restriction and consideration for such Award is paid for by past services rendered as a Service Provider.

-13-

9. Restricted Stock Units.

9.1 Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units.

9.2 Vesting Criteria and Other Terms. The Administrator will set vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit, or individual goals (including continued employment or service), applicable federal or state securities laws or any other basis determined by the Administrator in its discretion.

9.3 Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout.

9.4 Form and Timing of Payment. Payment of earned Restricted Stock Units will be made at the time(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may settle earned Restricted Stock Units in cash, Shares, or a combination of both.

Each Performance Award will have an initial value that is determined by the Administrator on or before its date of grant.

10.2 Objectives or Vesting Provisions and Other Terms. The Administrator will set any objectives or vesting provisions that, depending on the extent to which any such objectives or vesting provisions are met, will determine the value of the payout for the Performance Awards. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit, or individual goals (including continued employment or service), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion.

-14-

10.3 Earning Performance Awards. After an applicable Performance Period has ended, the holder of a Performance Award will be entitled to receive a payout for the Performance Award earned by the Participant over the Performance Period. The Administrator, in its discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Award.

10.4 Form and Timing of Payment. Payment of earned Performance Awards will be made at the time(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may settle earned Performance Awards in cash, Shares, or a combination of both.

10.5 Cancellation of Performance Awards. On the date set forth in the Award Agreement, all unearned or unvested Performance Awards will be forfeited to the Company, and again will be available for grant under this Plan.

11. Outside Director Award Limitations. No Outside Director may be granted, in any Fiscal Year, equity awards (including any Awards granted under this Plan), the value of which will be based on their grant date fair value determined in accordance with U.S. generally accepted accounting principles, and be provided any other compensation (including any cash retainers or fees) in amounts that, in the aggregate, exceed $750,000, provided that such amount is increased to $1,000,000 in the Fiscal Year of his or her initial service as an Outside Director. Any Awards or other compensation provided to an individual (a) for his or her services as an Employee, or for his or her services as a Consultant other than as an Outside Director, or (b) prior to the Closing, will be excluded for purposes of this Section 11.

12. Compliance With Section 409A. Awards will be designed and operated in such a manner that they are either exempt from the application of, or comply with, the requirements of Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under this Plan is intended to be exempt from or meet the requirements of Section 409A and will be construed and interpreted in accordance with such intent (including with respect to any ambiguities or ambiguous terms), except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A. In no event will the Company or any of its Parent or Subsidiaries have any responsibility, liability, or obligation to reimburse, indemnify, or hold harmless a Participant (or any other person) in respect of Awards, for any taxes, penalties or interest that may be imposed on, or other costs incurred by, Participant (or any other person) as a result of Section 409A.

13. Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise or as otherwise required by Applicable Laws, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (a) any leave of absence approved by the Company or (b) transfers between locations of the Company or between the Company, its Parent, or any of its Subsidiaries. For purposes of Incentive Stock Options, no such leave may exceed 3 months, unless reemployment

-15-

upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then 6 months following the 1^st day of such leave, any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option.

14. Limited Transferability of Awards. Unless determined otherwise by the Administrator, Awards may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent and distribution (which, for purposes of clarification, shall be deemed to include through a beneficiary designation if available in accordance with Section 6.6), and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate.

15. Adjustments; Dissolution or Liquidation; Merger or Change in Control.

15.1 Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, reclassification, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs (other than any ordinary dividends or other ordinary distributions), the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under this Plan, will adjust the number and class of shares of stock that may be delivered under this Plan or the number, class, and price of shares of stock covered by each outstanding Award, and numerical Share limits in Section 3.

15.2 Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action.

15.3 Merger or Change in Control. In the event of a merger of the Company with or into another corporation or other entity or a Change in Control, each outstanding Award will be treated as the Administrator determines (subject to the provisions of the following paragraph) without a Participant’s consent, including that (a) Awards will be assumed, or substantially equivalent awards will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof) with appropriate adjustments as to the number and kind of shares and prices; (b) upon written notice to a Participant, that the Participant’s Awards will terminate upon or immediately prior to the consummation of such merger or Change in Control; (c) outstanding Awards will vest and become exercisable, realizable, or payable, or restrictions applicable to an Award will lapse, in whole or in part prior to or upon consummation of such merger or Change in Control, and, to the extent the Administrator determines, terminate upon or immediately prior to the effectiveness of such merger or Change in Control; (d) (i) the termination of an Award in exchange for an amount of cash or property, if any, equal to the amount that would have been attained upon the exercise of the vested portion of such Award or realization of the Participant’s vested rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be

-16-

terminated by the Company without payment), or (ii) the replacement of such Award with other rights or property selected by the Administrator in its sole discretion; or (e) any combination of the foregoing. In taking any of the actions permitted under this Section 15.3, the Administrator will not be obligated to treat all Awards, all Awards held by a Participant, all Awards of the same type, or all portions of Awards, similarly.

In the event that the successor corporation does not assume or substitute for the Award (or portion thereof), the Participant will fully vest in and have the right to exercise his or her outstanding Options and Stock Appreciation Rights (or portions thereof) not assumed or substituted for, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock, Restricted Stock Units, or Performance Awards (or portions thereof) not assumed or substituted for will lapse, and, with respect to Awards with performance-based vesting (or portions thereof) not assumed or substituted for, all performance goals or other vesting criteria will be deemed achieved at 100% of target levels and all other terms and conditions met, in each case, unless specifically provided otherwise under the applicable Award Agreement or other written agreement authorized by the Administrator between the Participant and the Company or any of its Subsidiaries or Parents, as applicable. In addition, unless specifically provided otherwise under the applicable Award Agreement or other written agreement authorized by the Administrator between the Participant and the Company or any of its Subsidiaries or Parents, as applicable, if an Option or Stock Appreciation Right (or portion thereof) is not assumed or substituted in the event of a merger or Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right (or its applicable portion) will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right (or its applicable portion) will terminate upon the expiration of such period.

For the purposes of this Section 15.3, an Award will be considered assumed if, following the merger or Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit or Performance Award, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the merger or Change in Control.

Notwithstanding anything in this Section 15.3 to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent, in all cases, unless specifically provided otherwise under the applicable Award Agreement or other written agreement authorized by the Administrator between the Participant and the Company or any of its Subsidiaries or Parents, as applicable; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption.

-17-

Notwithstanding anything in this Section 15.3 to the contrary, and unless otherwise provided in an Award Agreement, if an Award that vests, is earned or paid-out under an Award Agreement is subject to Section 409A and if the change in control definition contained in the Award Agreement (or other agreement related to the Award, as applicable) does not comply with the definition of “change in control” for purposes of a distribution under Section 409A, then any payment of an amount that is otherwise accelerated under this Section will be delayed until the earliest time that such payment would be permissible under Section 409A without triggering any penalties applicable under Section 409A.

15.4 Outside Director Awards. With respect to Awards granted to an Outside Director, in the event of a Change in Control, the Participant will fully vest in and have the right to exercise Options or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares which otherwise would not be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at 100% of target levels and all other terms and conditions met, unless specifically provided otherwise under the applicable Award Agreement or other written agreement between the Participant and the Company or any of its Parents or Subsidiaries, as applicable, that is authorized by the Administrator.

16. Tax Withholding.

16.1 Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof) or such earlier time as any tax withholdings are due, the Company (or any of its Parent, Subsidiaries, or affiliates employing or retaining the services of a Participant, as applicable) will have the power and the right to deduct or withhold, or require a Participant to remit to the Company (or any of its Parent, Subsidiaries, or affiliates, as applicable) or a relevant tax authority, an amount sufficient to satisfy U.S. federal, state, local, non-U.S., and other taxes (including the Participant’s FICA or other social insurance contribution obligation) required to be withheld or paid with respect to such Award (or exercise thereof).

16.2 Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax liability or withholding obligation, in whole or in part by such methods as the Administrator shall determine, including (a) paying cash, check or other cash equivalents, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a fair market value equal to the minimum statutory amount required to be withheld or such greater amount as the Administrator may determine if such amount would not have adverse accounting consequences, as the Administrator determines in its sole discretion, (c) delivering to the Company already-owned Shares having a fair market value equal to the minimum statutory amount required to be withheld or such greater amount as the Administrator may determine, in each case, provided the delivery of such Shares will not result in any adverse accounting consequences, as the Administrator determines in its sole discretion, (d) selling a sufficient number of Shares otherwise deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise)

-18-

equal to the amount required to be withheld or paid, (e) such other consideration and method of payment for the meeting of tax liabilities or withholding obligations as the Administrator may determine to the extent permitted by Applicable Laws, or (f) any combination of the foregoing methods of payment. The amount of the withholding obligation will be deemed to include any amount which the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be determined or such greater amount as the Administrator may determine if such amount would not have adverse accounting consequences, as the Administrator determines in its sole discretion. The fair market value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

17. No Effect on Employment or Service. Neither this Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service Provider with the Company or its Subsidiaries or Parents, as applicable, nor will they interfere in any way with the Participant’s right or the right of the Company and its Subsidiaries or Parents, as applicable, to terminate such relationship at any time, free from any liability or claim under this Plan.

18. Date of Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant.

19. Term of Plan. Subject to Section 23, this Plan will become effective upon the latest to occur of (a) its adoption by the Board, (b) its approval by the Company’s stockholders, or (c) the time as of immediately prior to the Closing. The Plan will continue in effect until terminated under Section 20, but (i) no Options that qualify as incentive stock options within the meaning of Code Section 422 may be granted after 10 years from the earlier of the Board or stockholder approval of this Plan and (ii) Section 3.2 relating to the automatic share reserve increase will operate only until the 10-year anniversary of the earlier of the Board or stockholder approval of this Plan.

20. Amendment and Termination of this Plan.

20.1 Amendment and Termination. The Administrator, in its sole discretion, may amend, alter, suspend or terminate this Plan, or any part thereof, at any time and for any reason.

20.2 Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

20.3 Effect of Amendment or Termination. No amendment, alteration, suspension or termination of this Plan will materially impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of this Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under this Plan prior to the date of such termination.

-19-

21. Conditions Upon Issuance of Shares.

21.1 Legal Compliance. Shares will not be issued pursuant to an Award unless the exercise or vesting of such Award and the issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance.

21.2 Investment Representations. As a condition to the exercise or vesting of an Award, the Company may require the person exercising or vesting in such Award to represent and warrant at the time of any such exercise or vesting that the Shares are being acquired only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

22. Inability to Obtain Authority. If the Company determines it to be impossible or impractical to obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any registration or other qualification of the Shares under any U.S. state or federal law or non-U.S. law or under the rules and regulations of the U.S. Securities and Exchange Commission, the stock exchange on which Shares of the same class are then listed, or any other governmental or regulatory body, which authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the issuance and sale of any Shares hereunder, the Company will be relieved of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority, registration, qualification or rule compliance will not have been obtained.

23. Stockholder Approval. This Plan will be subject to approval by the stockholders of the Company within 12 months after the date the Board adopts this Plan. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

24. Forfeiture Events. The Administrator may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award will be subject to the reduction, cancellation, forfeiture, recoupment, reimbursement, or reacquisition upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include termination of such Participant’s status as an employee or other service provider for cause or any specified action or inaction by a Participant, whether before or after such termination of employment or other service, that would constitute cause for termination of such Participant’s status as a employee or other service provider. Notwithstanding any provisions to the contrary under this Plan, all Awards granted under this Plan will be subject to reduction, cancellation, forfeiture, recoupment, reimbursement, or reacquisition under any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Laws (the “Clawback Policy”). The Administrator may require a Participant to forfeit, return or reimburse the Company all or a portion of the Award and any amounts paid thereunder pursuant to the terms of the Clawback Policy or as necessary or appropriate to comply with Applicable Laws, including any reacquisition right regarding previously acquired Shares or other cash or property. Unless this Section 24 specifically is mentioned and waived in an Award Agreement or other document, no recovery of compensation under a Clawback Policy or otherwise will constitute an event that triggers or contributes to any right of a Participant to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company or any Parent or Subsidiary of the Company.

-20-

25. Governing Law. The Plan will be governed by, and construed in accordance with, the laws of the State of Delaware (except its choice-of-law provisions).

26. Construction; Interpretation. The titles of the Sections of this Plan are for convenience only and are not to be considered in construing this Plan. In this Plan, unless otherwise specified: (a) “includes” and “including” shall mean respectively includes and including without limitation; (b) the word “or” shall not be deemed to be used in the exclusive sense and shall instead be used in the inclusive sense to mean “and/or”; (c) words denoting any gender shall include all genders; (d) the word “hereunder” refers to under this Plan as a whole and not merely to the particular provision in which such words appear; and (e) except as otherwise indicated, all references in this Plan to a “Section” are intended to refer to a Section of this Plan.

2022 EMPLOYEE STOCK PURCHASE PLAN

1. Purpose. The purpose of this Plan is to provide employees of the Company and its Designated Companies with an opportunity to purchase Common Stock through accumulated Contributions. The Company intends for this Plan to have two components: a component that is intended to qualify as an “employee stock purchase plan” under Code Section 423 (the “423 Component”) and a component that is not intended to qualify as an “employee stock purchase plan” under Code Section 423 (the “Non-423 Component”). The provisions of the 423 Component, accordingly, will be construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with the requirements of Code Section 423. In addition, this Plan authorizes the grant of an option to purchase shares of Common Stock under the Non-423 Component that does not qualify as an “employee stock purchase plan” under Code Section 423; an option granted under the Non-423 Component will provide for substantially the same benefits as an option granted under the 423 Component, except that a Non-423 Component option may include features necessary to comply with applicable non-U.S. laws pursuant to rules, procedures or sub-plans adopted by the Administrator. Except as otherwise provided herein or by the Administrator, the Non-423 Component will operate and be administered in the same manner as the 423 Component.

For purposes of this Section 2.4, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company.

4. Administration. This Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to

(a) construe, interpret and apply the terms of this Plan,

(b) delegate ministerial duties to any of the Company’s employees,

(d) designate Subsidiaries as participating in the 423 Component or Non-423 Component,

(e) determine eligibility,

(f) adjudicate all disputed claims filed under this Plan, and

(g) establish such procedures that it deems necessary or advisable for the administration of this Plan (including to adopt such procedures, sub-plans, and appendices to the enrollment agreement as are necessary or appropriate to permit the participation in this Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans and appendices may take precedence over other provisions of this Plan, with the exception of Section 3, but unless otherwise superseded by the terms of such sub-plan or appendix, the provisions of this Plan will govern the operation of such sub-plan or appendix). Unless otherwise determined by the Administrator, the Eligible Employees eligible to participate in each sub-plan will participate in a separate Offering under the 423 Component, or if the terms would not qualify under the 423 Component, in the Non-423 Component, in either case unless such designation would cause the 423 Component to violate the requirements of Code Section 423.

Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to this Plan (including in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulations Section 1.423-2(f), the terms of an option granted under this Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of options granted under this Plan or the same Offering to employees resident solely in the U.S. Every finding, decision and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties.

-7-

5. Eligibility.

5.1 Offering Periods. Any Eligible Employee on a given Enrollment Date will be eligible to participate in this Plan, subject to the requirements of Section 7.

5.2 Non-U.S. Employees. Eligible Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether they also are citizens or residents of the United States or resident aliens (within the meaning of Code Section 7701(b)(1)(A))) may be excluded from participation in this Plan or an Offering if the participation of such Eligible Employees is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause this Plan or an Offering to violate Code Section 423. In the case of the Non-423 Component, an Eligible Employee may be excluded from participation in this Plan or an Offering if the Administrator has determined that participation of such Eligible Employee is not advisable or practicable.

5.3 Limitations. Any provisions of this Plan to the contrary notwithstanding, no Eligible Employee will be granted an option under this Plan (a) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Code Section 424(d)) would own capital stock of the Company or any Parent or Subsidiary of the Company or hold outstanding options to purchase such stock possessing 5% or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (b) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Code Section 423) of the Company or any Parent or Subsidiary of the Company accrues at a rate, which exceeds $25,000 worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for each calendar year in which such option is outstanding at any time, as determined in accordance with Code Section 423 and the regulations thereunder.

6. Offering Periods. This Plan will be implemented by Offering Periods as established by the Administrator from time to time. Offering Periods will expire on the earliest to occur of (a) the completion of the purchase of shares on the last Exercise Date occurring within 27 months of the applicable Enrollment Date on which the option to purchase shares was granted under this Plan, or (b) such shorter period established prior to the Enrollment Date of the Offering Period by the Administrator, from time to time, in its discretion, on a uniform and nondiscriminatory basis, for all options to be granted on such Enrollment Date. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future Offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter; provided, however, that no Offering Period may last more than 27 months.

7. Participation. An Eligible Employee may participate in this Plan pursuant to Section 5.1 by (a) submitting to the Company’s stock administration office (or its designee), a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose (which may be similar to the form attached hereto as Exhibit A), or (b) following an electronic or other enrollment procedure determined by the Administrator, in either case, on or before a date determined by the Administrator prior to an applicable Enrollment Date.

-8-

8. Contributions.

8.1 Contribution Amounts. At the time a Participant enrolls in this Plan pursuant to Section 7, he or she will elect to have Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the Offering Period in an amount not exceeding 15% of the Compensation, which he or she receives on each pay day during the Offering Period; provided, however, that unless and until determined otherwise by the Administrator, should a pay day occur on an Exercise Date, a Participant will have any Contributions made on such day applied to his or her account under the then-current Purchase Period or Offering Period (i.e., for which the Exercise Date occurs on such day).

8.2 Contribution Methods. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to this Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Offering Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 12 (or Participant’s participation is terminated as provided in Section 13).

(a) In the event Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day on or prior to the last Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 12 (or Participant’s participation is terminated as provided in Section 13).

(b) All Contributions made for a Participant will be credited to his or her account under this Plan and Contributions will be made in whole percentages of his or her Compensation only. A Participant may not make any additional payments into such account.

8.3 Participant Changes to Contributions. A Participant may discontinue his or her participation in this Plan as provided under Section 12. Until and unless determined otherwise by the Administrator, in its sole discretion, during any Offering Period, a Participant may not increase the rate of his or her Contributions and may decrease the rate of his or her Contributions only one time, provided that such decrease is to a Contribution rate of 0%. In addition, until and unless determined otherwise by the Administrator, in its sole discretion, during any Offering Period, a Participant may increase or decrease the rate of his or her Contributions (as a whole percent to a rate between 0% and the maximum percentage specified in Section 8.1), which Contribution rate adjustment will become effective upon the commencement of the next Offering Period and remain in effect for subsequent Offering Periods and, except as set forth in the immediately preceding sentence, any such adjustment will not affect the Contribution rate for any ongoing Offering Period.

(a) A Participant may make a Contribution rate adjustment pursuant to this Section 8.3 by (A) properly completing and submitting to the Company’s stock administration office (or its designee), a new subscription agreement authorizing the change in Contribution rate in the form provided by the Administrator for such purpose, or (B) following an electronic or other procedure prescribed by the Administrator, in either case, on or before a date determined by the Administrator prior to (x) the scheduled beginning of the first Offering Period to be affected or

-9-

(y) an applicable Exercise Date, as applicable. If a Participant has not followed such procedures to change the rate of Contributions, the rate of his or her Contributions will continue at the originally elected rate throughout the Offering Period and future Offering Periods (unless the Participant’s participation is terminated as provided in Sections 12 or 13).

(b) The Administrator may, in its sole discretion, limit or amend the nature or number of Contribution rate changes (including to permit, prohibit or limit increases or decreases to rate changes) that may be made by Participants during any Purchase Period or Offering Period, and may establish such other conditions or limitations as it deems appropriate for Plan administration.

(c) Except as provided by this Section 8.3, any change in Contribution rate made pursuant to this Section 8.3 will be effective as of the first full payroll period following 5 business days after the date on which the change is made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in Contribution rate earlier).

8.4 Other Contribution Changes. Notwithstanding the foregoing, to the extent necessary to comply with Code Section 423(b)(8) and Section 5.3 (which generally limit participation in an Offering Period pursuant to certain Applicable Laws), a Participant’s Contributions may be decreased to 0% by the Administrator at any time during an Offering Period (or a Purchase Period, as applicable). Subject to Code Section 423(b)(8) and Section 5.3, Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Offering Period (or Purchase Period, as applicable) scheduled to end in the following calendar year, unless the Participant’s participation has terminated as provided in Sections 12 or 13.

8.5 Cash Contributions. Notwithstanding any provisions to the contrary in this Plan, the Administrator may allow Participants to participate in this Plan via cash contributions instead of payroll deductions if (a) payroll deductions are not permitted or advisable under Applicable Laws, (b) the Administrator determines that cash contributions are permissible for Participants participating in the 423 Component or (c) the Participants are participating in the Non-423 Component.

8.6 Tax Withholdings. At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued under this Plan is disposed of (or at any other time that a taxable event related to this Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding or payment on account obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock (or any other time that a taxable event related to this Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to the sale or early disposition of Common Stock by the Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or use any other method of withholding the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulations Section 1.423-2(f).

-10-

8.7 Use of Funds. The Company may use all Contributions received or held by it under this Plan for any corporate purpose, and the Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to this Plan by Participants be segregated from the Company’s general corporate funds or deposited with an independent third party, provided that, if such segregation or deposit with an independent third party is required by Applicable Laws, it will apply to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulations Section 1.423-2(f). Until shares of Common Stock are issued, Participants will have only the rights of an unsecured creditor with respect to such shares.

9. Grant of Option. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price.

9.1 Certain Option Limits. In no event will an Eligible Employee be permitted to purchase during each Offering Period more than 8,500 shares of Common Stock (subject to any adjustment pursuant to Section 17), and provided further that such purchase will be subject to the limitations set forth in Sections 3 and 5.3 and in the subscription agreement. The Administrator, in its absolute discretion, may increase or decrease the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period or Offering Period, as applicable.

9.2 Option Receipt. The Eligible Employee may accept the grant of an option under this Plan by electing to participate in this Plan in accordance with the requirements of Section 7.

9.3 Option Term. Exercise of the option will occur as provided in Section 10, unless the Participant’s participation has terminated pursuant to Sections 12 or 13. The option will expire on the last day of the Offering Period.

10. Exercise of Option.

10.1 Automatic Exercise. Unless a Participant’s participation in this Plan has terminated as provided in Sections 12 and 13, his or her option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares of Common Stock subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in the Participant’s account for the subsequent Purchase Period or Offering Period, as applicable, subject to earlier termination of the Participant’s participation in this Plan as provided in Sections 12 or 13. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the Participant. During a Participant’s lifetime, a Participant’s option to purchase shares of Common Stock under this Plan is exercisable only by him or her.

-11-

10.2 Pro Rata Allocations. If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (a) the number of shares of Common Stock that were available for sale under this Plan on the Enrollment Date of the applicable Offering Period, or (b) the number of shares of Common Stock available for sale under this Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 18. The Company may make a pro rata allocation of the shares of Common Stock available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares of Common Stock for issuance under this Plan by the Company’s stockholders subsequent to such Enrollment Date.

11. Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares of Common Stock purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that shares of Common Stock be deposited directly with a broker designated by the Company or with a trustee or designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares of Common Stock be retained with such broker, trustee or agent for a designated period of time or may establish other procedures to permit tracking of disqualifying dispositions or other dispositions of such shares. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under this Plan until such shares have been purchased and delivered to the Participant as provided in this Section 11.

12. Withdrawal.

12.1 Withdrawal Procedures. A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or her option under this Plan at any time by (a) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose (which may be similar to the form attached hereto as Exhibit B), or (b) following an electronic or other withdrawal procedure determined by the Administrator. The Administrator may set forth a deadline of when a withdrawal must occur to be effective prior to a given Exercise Date in

-12-

accordance with policies it may approve from time to time. All of the Participant’s Contributions credited to his or her account will be paid to such Participant as soon as administratively practicable after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of shares of Common Stock will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in this Plan in accordance with the provisions of Section 7.

12.2 No Effect on Future Participation. A Participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws.

13. Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be deemed to have elected to withdraw from this Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under this Plan will be returned to such Participant, or, in the case of his or her death, to the person or persons entitled thereto, and such Participant’s option will be automatically terminated. Unless determined otherwise by the Administrator in a manner that, with respect to an Offering under the 423 Component, is permitted by, and compliant with, Code Section 423, a Participant whose employment transfers between entities through a termination with an immediate rehire (with no break in service) by the Company or a Designated Company will not be treated as terminated under this Plan; however, if a Participant transfers from an Offering under the 423 Component to the Non-423 Component, the exercise of the option will be qualified under the 423 Component only to the extent it complies with Code Section 423; further, no Participant will be deemed to switch from an Offering under the Non-423 Component to an Offering under the 423 Component or vice versa unless (and then only to the extent) such switch would not cause the 423 Component or any option thereunder to fail to comply with Code Section 423.

14. Section 409A. This Plan is intended to be exempt from the application of Section 409A, and, to the extent not exempt, is intended to comply with Section 409A and any ambiguities herein will be interpreted to so be exempt from, or comply with, Section 409A. In furtherance of the foregoing and notwithstanding any provision in this Plan to the contrary, if the Administrator determines that an option granted under this Plan may be subject to Section 409A or that any provision in this Plan would cause an option under this Plan to be subject to Section 409A, the Administrator may amend the terms of this Plan or of an outstanding option granted under this Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under this Plan from or to allow any such options to comply with Section 409A, but only to the extent any such amendments or action by the Administrator would not violate Section 409A. Notwithstanding the foregoing, the Company and any of its Parent or Subsidiaries will have no liability, obligation or responsibility to reimburse, indemnify, or hold harmless a Participant or any other party if the option to purchase Common Stock under this Plan that is intended to be exempt from or compliant with Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the option to purchase Common Stock under this Plan is compliant with Section 409A.

-13-

15. Rights as Stockholder. Until the shares of Common Stock are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a Participant will have only the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares. Shares of Common Stock to be delivered to a Participant under this Plan will be registered in the name of the Participant or, if so required under Applicable Laws, in the name of the Participant and his or her spouse.

16. Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under this Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will or the laws of descent and distribution) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will 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 12.

17. Adjustments, Dissolution, Liquidation, Merger or Change in Control.

17.1 Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, reclassification, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs (other than any ordinary dividends or other ordinary distributions), the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under this Plan, will adjust the number and class of common stock that may be delivered under this Plan, the Purchase Price per share, the class and the number of shares of common stock covered by each option under this Plan that has not yet been exercised, and the numerical share limits of Sections 3 and 9.1.

17.2 Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, 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 will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 12 (or, prior to such New Exercise Date, Participant’s participation has terminated as provided in Section 13).

17.3 Merger or Change in Control. In the event of a merger of the Company with or into another corporation or other entity or Change in Control, each outstanding option will 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 refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period will end. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator

-14-

will notify each Participant in writing or electronically 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 will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 12 (or, prior to such New Exercise Date, Participant’s participation has terminated as provided in Section 13).

18. Amendment or Termination.

18.1 Amendment, Suspension, Termination. The Administrator, in its sole discretion, may amend, alter, suspend, or terminate this Plan, or any part thereof, at any time and for any reason. If this Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 17). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under Applicable Laws, as further set forth in Section 22) as soon as administratively practicable.

18.2 Certain Administrator Changes. Without stockholder consent and without limiting Section 18.1, the Administrator will be entitled to change the Offering Periods and any Purchase Periods, designate separate Offerings, limit the frequency or number of changes in the amount withheld during an Offering Period, establish the exchange rate applicable to amounts withheld in a currency other than U.S. dollars, permit Contributions 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 Contribution elections, establish reasonable waiting and adjustment periods or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent with this Plan.

18.3 Changes Due to Accounting Consequences. In the event the Administrator determines that the ongoing operation of this Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate this Plan to reduce or eliminate such accounting consequence including:

(a) amending this Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;

(b) altering the Purchase Price for any Purchase Period or Offering Period including a Purchase Period or Offering Period underway at the time of the change in Purchase Price;

-15-

(c) shortening any Purchase Period or Offering Period by setting a New Exercise Date, including a Purchase Period or Offering Period underway at the time of the Administrator action;

(d) reducing the maximum percentage of Compensation a Participant may elect to set aside as Contributions; and

(e) reducing the maximum number of shares of Common Stock a Participant may purchase during any Purchase Period or Offering Period.

Such modifications or amendments will not require stockholder approval or the consent of any Plan Participants.

19. Conditions Upon Issuance of Shares.

19.1 Legal Compliance. Shares of Common Stock will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance.

19.2 Investment Representations. As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required.

20. Term of Plan. This Plan will become effective upon the latest to occur of (a) its adoption by the Board, (b) its approval by the Company’s stockholders, or (c) the time as of immediately prior to the Closing.

22. Interest. No interest will accrue on the Contributions of a participant in this Plan, except as may be required by Applicable Laws, as determined by the Company, and if so required by the laws of a particular jurisdiction, will apply, with respect to Offerings under the 423 Component, to all Participants in the relevant Offering, except to the extent otherwise permitted by U.S. Treasury Regulations Section 1.423-2(f).

23. No Effect on Employment. Neither this Plan nor any option under this Plan will confer upon any Participant any right with respect to continuing the Participant’s employment with the Company or its Subsidiaries or Parents, as applicable, nor will they interfere in any way with the Participant’s right or the right of the Company and its Subsidiaries or Parents, as applicable, to terminate such employment relationship at any time, free from any liability or any claim under this Plan.

-16-

24. Reports. Individual accounts will be maintained for each Participant in this Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any.

25. Notices. All notices or other communications by a Participant to the Company under or in connection with this Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

26. Legal Construction.

26.1 Severability. If any provision of this Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality, or unenforceability will not affect the remaining parts of this Plan, and this Plan will be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal, or unenforceable provision had not been included.

26.2 Governing Law. This Plan will be governed by, and construed in accordance with, the laws of the State of California, but without regard to its conflict of law provisions.

27. Compliance with Applicable Laws. The terms of this Plan are intended to comply with all Applicable Laws and will be construed accordingly.

28. Automatic Transfer to Low Price Offering Period. Unless determined otherwise by the Administrator, this Section 28 applies to an Offering Period to the extent such Offering Period provides for more than one Exercise Date within such Offering Period. To the extent permitted by Applicable Laws, if the Fair Market Value of a share of Common Stock on any Exercise Date in an Offering Period is less than the Fair Market Value of a share of Common Stock on the Enrollment Date of such Offering Period, then all Participants in such Offering Period will be withdrawn automatically from such Offering Period immediately after the exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following Offering Period as of the first day thereof.

29. Construction; Interpretation. The titles of the Sections of this Plan are for convenience only and are not to be considered in construing this Plan. In this Plan, unless otherwise specified: (a) “includes” and “including” shall mean respectively includes and including without limitation; (b) the word “or” shall not be deemed to be used in the exclusive sense and shall instead be used in the inclusive sense to mean “or”; (c) words denoting any gender shall include all genders; and (d) except as otherwise indicated, all references in this Plan to a “Section” are intended to refer to a Section of this Plan.

APEXIGEN, INC.

2022 EMPLOYEE STOCK PURCHASE PLAN

SUBSCRIPTION AGREEMENT


_____ Original Application		Offering Date: _________________

_____ Change in Payroll Deduction Rate

1. ____________________ hereby elects to participate in the Apexigen, Inc. 2022 Employee Stock Purchase Plan (the “Plan”) and subscribes to purchase shares of the Company’s Common Stock in accordance with this Subscription Agreement and the Plan. Any capitalized terms not specifically defined in this Subscription Agreement will have the meaning ascribed to them under the Plan.

2. I hereby authorize and consent to payroll deductions from each paycheck in the amount of ____% of my Compensation on each payday (from 0% to 15%) during the Offering Period in accordance with the Plan. (Please note that no fractional percentages are permitted.) I understand that only my first election to decrease the rate of my payroll deductions to 0% may be applied with respect to an ongoing Offering Period in accordance with the terms of the Plan, and (a) any subsequent election to decrease the rate of my payroll deductions during the same Offering Period or (b) any election to increase the rate of my payroll deductions during any Offering Period will not be applied to the ongoing Offering Period.

3. I understand that said payroll deductions will be accumulated for the purchase of shares of Common Stock at the applicable Purchase Price determined in accordance with the Plan. I understand that if I do not withdraw from an Offering Period, any accumulated payroll deductions will be used to automatically exercise my option and purchase Common Stock under the Plan. I further understand that if I am outside of the U.S., my payroll deductions will be converted to U.S. dollars at an exchange rate selected by the Company on the purchase date.

4. I have received a copy of the complete Plan and its accompanying prospectus. I understand that my participation in the Plan is in all respects subject to the terms of the Plan.

5. Shares of Common Stock purchased for me under the Plan should be issued in the name(s) of _____________ (Eligible Employee or Eligible Employee and spouse only).

6. If I am a U.S. taxpayer, I understand that if I dispose of any shares received by me pursuant to the Plan within 2 years after the Offering Date (the first day of the Offering Period during which I purchased such shares) or 1 year after the Exercise Date, I will be treated for federal income tax purposes as having received ordinary income at the time of such disposition in an amount equal to the excess of the fair market value of the shares at the time such shares were purchased by me over the price that I paid for the shares. I hereby agree to notify the Company in writing within 30 days after the date of any disposition of my shares and I will make adequate provision for federal, state or other tax withholding obligations, if any, which arise upon the disposition of the Common Stock. The Company may, but will not be obligated to, withhold from my compensation the amount necessary to meet any applicable

-18-

withholding obligation including any withholding necessary to make available to the Company any tax deductions or benefits attributable to sale or early disposition of Common Stock by me. If I dispose of such shares at any time after the expiration of the 2-year and 1-year holding periods, I understand that I will be treated for federal income tax purposes as having received income only at the time of such disposition, and that such income will be taxed as ordinary income only to the extent of an amount equal to the lesser of (a) the excess of the fair market value of the shares at the time of such disposition over the purchase price which I paid for the shares, or (b) 15% of the fair market value of the shares on the first day of the Offering Period. The remainder of the gain, if any, recognized on such disposition will be taxed as capital gain.

7. For employees that may be subject to tax in non U.S. jurisdictions, I acknowledge and agree that, regardless of any action taken by the Company or any Designated Company with respect to any or all income tax, social security, social insurances, National Insurance Contributions, payroll tax, fringe benefit, or other tax-related items related to my participation in the Plan and legally applicable to me including in connection with the grant of such options, the purchase or sale of shares of Common Stock acquired under the Plan or the receipt of any dividends on such shares (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains my responsibility and may exceed the amount actually withheld by the Company or a Designated Company. Furthermore, I acknowledge that the Company or any Designated Company (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the options under the Plan and (b) do not commit to and are under no obligation to structure the terms of the grant of options or any aspect of my participation in the Plan to reduce or eliminate my liability for Tax-Related Items or achieve any particular tax result. Further, if I have become subject to tax in more than one jurisdiction between the date of my enrollment and the date of any relevant taxable or tax withholding event, as applicable, I acknowledge that the Company or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to the purchase of shares of Common Stock under the Plan or any other relevant taxable or tax withholding event, as applicable, I agree to make adequate arrangements satisfactory to the Company or the applicable Designated Company to satisfy all Tax-Related Items. In this regard, I authorize the Company or the applicable Designated Company, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (a) withholding from my wages or Compensation paid to me by the Company or the applicable Designated Company; or (b) withholding from proceeds of the sale of the shares of Common Stock purchased under the Plan either through a voluntary sale or through a mandatory sale arranged by the Company (on my behalf pursuant to this authorization). Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable maximum withholding rates, in which case I will receive a refund of any over-withheld amount in cash and will have no entitlement to the Common Stock equivalent.

Finally, I agree to pay to the Company or the applicable Designated Company any amount of Tax-Related Items that the Company or the applicable Designated Company may be required to withhold as a result of my participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to purchase shares of Common Stock under the Plan on my behalf or refuse to issue or deliver the shares or the proceeds of the sale of shares if I fail to comply with my obligations in connection with the Tax-Related Items.

-19-

8. By electing to participate in the Plan, I acknowledge, understand and agree that:

(a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, to the extent provided for in the Plan;

(b) all decisions with respect to future grants under the Plan, if applicable, will be at the sole discretion of the Company;

(c) the grant of options under the Plan will not create a right to employment or be interpreted as forming or amending an employment or service contract with the Company, or any Designated Company, and will not interfere with the ability of the Company or any Designated Company, as applicable, to terminate my employment (if any);

(d) I am voluntarily participating in the Plan;

(e) the options granted under the Plan and the shares of Common Stock underlying such options, and the income and value of same, are not intended to replace any pension rights or compensation;

(f) the options granted under the Plan and the shares of Common Stock underlying such options, and the income and value of same, are not part of my normal or expected compensation for any purpose, including calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or similar payments;

(g) the future value of the shares of Common Stock offered under the Plan is unknown, indeterminable and cannot be predicted with certainty;

(h) the shares of Common Stock that I acquire under the Plan may increase or decrease in value, even below the Purchase Price;

(i) no claim or entitlement to compensation or damages will arise from the forfeiture of options granted to me under the Plan as a result of the termination of my status as an Eligible Employee (for any reason whatsoever, and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any) and, in consideration of the grant of options under the Plan to which I am otherwise not entitled, I irrevocably agree never to institute a claim against the Company, or any Designated Company, waive my ability, if any, to bring such claim, and release the Company, and any Designated Company from any such claim that may arise; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, I will be deemed irrevocably to have agreed to not to pursue such claim and agree to execute any and all documents necessary to request dismissal or withdrawal of such claim; and

-20-

(j) in the event of the termination of my status as an Eligible Employee (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where I am employed or the terms of my employment agreement, if any), my right to participate in the Plan and any options granted to me under the Plan, if any, will terminate effective as of the date that I am no longer actively employed by the Company or one of its Designated Companies and, in any event, will not be extended by any notice period mandated under the employment laws in the jurisdiction in which I am employed or the terms of my employment agreement, if any (e.g., active employment would not include a period of “garden leave” or similar period pursuant to the employment laws in the jurisdiction in which I am employed or the terms of my employment agreement, if any); the Company will have the exclusive discretion to determine when I am no longer actively employed for purposes of my participation in the Plan (including whether I may still be considered to be actively employed while on a leave of absence).

9. I understand that the Company or any Designated Company may collect, where permissible under applicable law certain personal information about me, including my name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of Common Stock or directorships held in the Company, details of all options granted under the Plan or any other entitlement to shares of Common Stock awarded, canceled, exercised, vested, unvested or outstanding in my favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. I understand that Company may transfer my Data to the United States, which is not considered by the European Commission to have data protection laws equivalent to the laws in my country. I understand that the Company will transfer my Data to its designated broker, or such other stock plan service provider as may be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. I understand that the recipients of the Data may be located in the United States or elsewhere, and that a recipient’s country of operation (e.g., the United States) may have different, including less stringent, data privacy laws that the European Commission or my jurisdiction does not consider to be equivalent to the protections in my country. I understand that I may request a list with the names and addresses of any potential recipients of the Data by contacting my local human resources representative. I authorize the Company, the Company’s designated broker and any other possible recipients which may assist the Company with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of implementing, administering and managing my participation in the Plan. I understand that Data will be held only as long as is necessary to implement, administer and manage my participation in the Plan. I understand that that I may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing my local human resources representative. Further, I understand that I am providing the consents herein on a purely voluntary basis. If I do not consent, or if I later seek to revoke my consent, my employment status or career with the Company or any Designated Company will not be adversely affected; the only adverse consequence of refusing or withdrawing my consent is that the Company would not be able to grant me options under the Plan or other equity awards, or administer or maintain such awards. Therefore, I understand that refusing or withdrawing my consent may affect my ability to participate in the Plan. For more information on the consequences of my refusal to consent or withdrawal of consent, I understand that I may contact my local human resources representative.

-21-

If I am an employee outside the U.S., I understand that in accordance with applicable law, I have the right to access, and to request a copy of, the Data held about me. I also understand that I have the right to discontinue the collection, processing, or use of my Data, or supplement, correct, or request deletion of my Data. To exercise my rights, I may contact my local human resources representative.

I hereby explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of my personal data as described herein and any other Plan materials by and among, as applicable, the Company and its Subsidiaries for the exclusive purpose of implementing, administering and managing my participation in the Plan. I understand that my consent will be sought and obtained for any processing or transfer of my data for any purpose other than as described in the enrollment form and any other plan materials.

10. If I have received the Subscription Agreement or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control, subject to applicable laws.

11. The provisions of the Subscription Agreement and these appendices are severable and if any one or more provisions are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions nevertheless will be binding and enforceable.

12. Notwithstanding any provisions in this Subscription Agreement, I understand that if I am working or resident in a country other than the United States, my participation in the Plan also will be subject to the additional terms and conditions set forth on Appendix A and any special terms and conditions for my country set forth on Appendix A. Moreover, if I relocate to one of the countries included in Appendix A, the special terms and conditions for such country will apply to me to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. Appendix A constitutes part of this Subscription Agreement and the provisions of this Subscription Agreement govern each Appendix (to the extent not superseded or supplemented by the terms and conditions set forth in the applicable Appendix).

13. I hereby agree to be bound by the terms of the Plan. The effectiveness of this Subscription Agreement is dependent upon my eligibility to participate in the Plan.
