Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

We have entered into indemnification agreements with each of our current directors and executive officers. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We also intend to enter into indemnification agreements with our future directors and executive officers.

Section 145 of the Delaware General Corporation Law (the “DGCL”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent to the Registrant. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise. Our amended and restated bylaws provide for indemnification by the Registrant of its directors, officers and employees to the fullest extent permitted by the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (4) for any transaction from which the director derived an improper personal benefit. Our amended and restated certificate of incorporation provides for such limitation of liability.

We maintain standard policies of insurance under which coverage is provided (a) to our directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act and (b) to us with respect to payments we may make to our officers and directors pursuant to the above indemnification provision or otherwise as a matter of law.

Item 7. Exemption From Registration Claimed.

Not applicable.

Item 8. Exhibits.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

2. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the city of Dallas, State of Texas, on November 15, 2021.

SIGNATURES AND POWERS OF ATTORNEY

Each of the undersigned officers and directors of the Registrant hereby severally constitutes and appoints Mei Mei Hu and René Paula Molina, and each of them acting alone, as his or her true and lawful attorneys-in-fact and agents, with full power of substitution and resubstitution, for him or her and in his or her name, place and stead, and in any and all capacities, to sign any and all amendments (including post-effective amendments) to this registration statement and any subsequent registration statement filed pursuant to Rule 462 under the Securities Act, and to file the same, with all exhibits thereto and other documents in connection therewith, with the Commission and any applicable securities exchange or securities self-regulatory body, granting unto said attorneys-in-fact and agents, and each of them, full power and authority to do and perform each and every act and thing requisite and necessary to be done in and about the premises, as fully to all intents and purposes as he or she might or could do in person, hereby ratifying and confirming all that said attorneys-in-fact and agents, or either of them individually, or their or his or her substitute or substitutes, may lawfully do or cause to be done by virtue hereof.

Pursuant to the requirements of the Securities Act, this Registration Statement has been signed by the following persons in the capacities and on the dates indicated.

Vaxxinity, Inc.

Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as counsel for Vaxxinity, Inc., a Delaware corporation (the “Company”), in connection with the registration statement on Form S-8 (the “Registration Statement”), filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the 31,714,348 shares of the Company’s Class A common stock, par value $0.0001 per share (the “Shares”), issuable under the (i) the Vaxxinity, Inc. 2021 Stock Option and Grant Plan, (ii) the Vaxxinity, Inc. 2021 Omnibus Incentive Compensation Plan, (iii) the Vaxxinity, Inc. 2021 Employee Stock Purchase Plan and (iv) the Non-Qualified Stock Option Award Agreements with each of Mei Mei Hu and Lou Reese, respectively (collectively, the “Stock Plans”).

In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including, without limitation: (a) the Second Amended and Restated Certificate of Incorporation of the Company; (b) the Amended and Restated Bylaws of the Company; (c) certain resolutions adopted by the Board of Directors of the Company; and (d) the Stock Plans.

In rendering our opinion, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such latter documents. As to all questions of fact material to this opinion that have not been independently established, we have relied upon certificates or comparable documents of officers and representatives of the Company.

Based on the foregoing and in reliance thereon, and subject to compliance with applicable state securities laws, we are of opinion that the Shares when, and if, issued pursuant to the terms of the Stock Plans will be validly issued, fully paid and non-assessable.

We are admitted to practice in the State of New York, and we express no opinion as to matters governed by any laws other than the General Corporation Law of the State of Delaware and the Federal laws of the United States of America. The reference and limitation to “General Corporation Law of the State of Delaware” includes the statutory provisions and all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.

This Stock Option is not intended to qualify as an “incentive stock option” as defined in Section 422(b) of the Internal Revenue Code of 1986, as amended from time to time (the “Code”). This Stock Option is not being granted under any equity incentive compensation plan of the Company. Notwithstanding the preceding sentence, this Grant Notice and the Agreement shall be construed as if this Stock Option had been granted under the Vaxxinity, Inc. 2021 Stock Option and Grant Plan (as it may be amended from time to time in accordance with such plan, the “Plan”) in accordance and consistent with, and subject to, the provisions of the Plan, the terms of which are incorporated herein and in the Agreement by reference; provided that all references in the Plan to Stock shall be deemed to be references to Common Stock as used herein. Except as expressly set forth herein, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Grant Notice and the Agreement, the terms and conditions of this Grant Notice and the Agreement shall prevail.

Attachments: Non-Qualified Stock Option Agreement, 2021 Stock Option and Grant Plan

NON-QUALIFIED STOCK OPTION AGREEMENT

All capitalized terms used herein and not otherwise defined shall have the respective meanings set forth in the Grant Notice and the Plan.

1. Vesting, Exercisability and Termination.

(a) No portion of this Stock Option may be exercised until such portion shall have vested and become exercisable.

(b) Except as set forth below, and subject to the determination of the Committee in its sole discretion to accelerate the vesting schedule hereunder, this Stock Option shall be vested and exercisable on the respective dates indicated below:

(i) This Stock Option shall initially be unvested and unexercisable.

(ii) This Stock Option shall vest and become exercisable in accordance with the Vesting Schedule set forth in the Grant Notice.

(c) Termination. Except as may otherwise be provided by the Committee, if the Optionee’s Service Relationship is terminated, the period within which to exercise this Stock Option will be subject to earlier termination as set forth below (and if not exercised within such period, shall thereafter terminate subject, in each case, to Section 3(c) of the Plan):

(i) Termination Due to Death or Disability. If the Optionee’s Service Relationship terminates by reason of such Optionee’s death or Disability, this Stock Option may be exercised, to the extent exercisable on the date of such termination, by the Optionee, the Optionee’s legal representative or legatee for a period of 12 months from the date of death or Disability or until the Expiration Date, if earlier.

(ii) Other Termination.

For purposes hereof, the Committee’s determination of the reason for termination of the Optionee’s Service Relationship shall be conclusive and binding on the Optionee and his or her representatives or legatees and any Permitted Transferee. Any portion of this Stock Option that is not vested and exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void.

2. Exercise of Stock Option.

(a) The Optionee may exercise this Stock Option only in the following manner: Prior to the Expiration Date, the Optionee may deliver a Stock Option exercise notice (an “Exercise Notice”) in the form of Appendix A hereto indicating his or her election to purchase some or all of the Shares with respect to which this Stock Option is then exercisable. Such notice shall specify the number of Shares to be purchased. Payment of the purchase price may be made by one or more of the methods described in Section 5 of the Plan, subject to the limitations contained in such Section of the Plan, including the requirement that the Committee specifically approve in advance certain payment methods.

(b) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date.

3. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be construed as if this Stock Option has been granted under the Plan in accordance and consistent with, and subject to and governed by all the terms and conditions of the Plan.

4. Transferability of Stock Option. This Stock Option is personal to the Optionee and is not transferable by the Optionee in any manner other than by will or by the laws of descent and distribution. The Stock Option may be exercised during the Optionee’s lifetime only by the Optionee (or by the Optionee’s guardian or personal representative in the event of the Optionee’s incapacity). The Optionee may elect to designate a beneficiary by providing written notice of the name of such beneficiary to the Company, and may revoke or change such designation at any time by filing written notice of revocation or change with the Company; such beneficiary may exercise the Optionee’s Stock Option in the event of the Optionee’s death to the extent provided herein. If the Optionee does not designate a beneficiary, or if the designated beneficiary predeceases the Optionee, the legal representative of the Optionee may exercise this Stock Option to the extent provided herein in the event of the Optionee’s death.

If, as a result of any reorganization, recapitalization, reincorporation, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Common Stock, the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number or kind of securities of the Company, the restrictions contained in this Agreement shall apply with equal force to additional and/or substitute securities, if any, received by the Optionee in exchange for, or by virtue of his or her ownership of, this Stock Option or Shares acquired pursuant thereto.

3

(c) Change and Modifications. This Agreement may not be orally changed, modified or terminated, nor shall any oral waiver of any of its terms be effective. This Agreement may be changed, modified or terminated only by an agreement in writing signed by the Company and the Optionee.

(d) Governing Law. This Agreement shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of Texas, without regard to conflict of law principles that would result in the application of any law other than the law of the State of Texas.

(e) Headings. The headings are intended only for convenience in finding the subject matter and do not constitute part of the text of this Agreement and shall not be considered in the interpretation of this Agreement.

(f) Saving Clause. If any provision(s) of this Agreement shall be determined to be illegal or unenforceable, such determination shall in no manner affect the legality or enforceability of any other provision hereof.

(g) Notices. All notices, requests, consents and other communications shall be in writing and be deemed given when delivered personally, by telex or facsimile transmission or when received if mailed by first class registered or certified mail, postage prepaid. Notices to the Company or the Optionee shall be addressed as set forth underneath their signatures below, or to such other address or addresses as may have been furnished by such party in writing to the other.

(h) Benefit and Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto, their respective successors, assigns, and legal representatives. The Company has the right to assign this Agreement, and such assignee shall become entitled to all the rights of the Company hereunder to the extent of such assignment.

(i) Counterparts. For the convenience of the parties and to facilitate execution, this Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same document.

(j) Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements and discussions between the parties concerning such subject matter.

7. Dispute Resolution.

(a) Except as provided below, any dispute arising out of or relating to the Plan or this Stock Option, this Agreement, or the breach, termination or validity of the Plan, this Stock Option or this Agreement, shall be finally settled by binding arbitration conducted expeditiously in accordance with the J.A.M.S./Endispute Comprehensive Arbitration Rules and Procedures (the “J.A.M.S. Rules”). The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16, and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction thereof. The place of arbitration shall be a mutually agreed upon location in Dallas, Texas.

4

(b) The arbitration shall commence within 60 days of the date on which a written demand for arbitration is filed by any party hereto. In connection with the arbitration proceeding, the arbitrator shall have the power to order the production of documents by each party and any third-party witnesses. In addition, each party may take up to three depositions as of right, and the arbitrator may in his or her discretion allow additional depositions upon good cause shown by the moving party. However, the arbitrator shall not have the power to order the answering of interrogatories or the response to requests for admission. In connection with any arbitration, each party to the arbitration shall provide to the other, no later than seven business days before the date of the arbitration, the identity of all persons that may testify at the arbitration and a copy of all documents that may be introduced at the arbitration or considered or used by a party’s witness or expert. The arbitrator’s decision and award shall be made and delivered within six months of the selection of the arbitrator. The arbitrator’s decision shall set forth a reasoned basis for any award of damages or finding of liability. The arbitrator shall not have power to award damages in excess of actual compensatory damages and shall not multiply actual damages or award punitive damages, and each party hereby irrevocably waives any claim to such damages.

(c) The Company, the Optionee, each party to the Agreement and any other holder of Shares issued pursuant to this Agreement (each, a “Party”) covenants and agrees that such party will participate in the arbitration in good faith. This Section 7 applies equally to requests for temporary, preliminary or permanent injunctive relief, except that in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding immediate and irreparable harm.

(d) Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District Court of competent jurisdiction for the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other jurisdiction which may be called upon to grant an enforcement of the judgment of any such court. Each Party hereby consents to service of process by registered mail at the address to which notices are to be given. Each Party agrees that its, his or her submission to jurisdiction and its, his or her consent to service of process by mail is made for the express benefit of each other Party. Final judgment against any Party in any such action, suit or proceeding may be enforced in other jurisdictions by suit, action or proceeding on the judgment, or in any other manner provided by or pursuant to the laws of such other jurisdiction.

5

8. Waiver of Statutory Information Rights. The Optionee understands and agrees that, but for the waiver made herein, the Optionee would be entitled, upon written demand under oath stating the purpose thereof, to inspect for any proper purpose, and to make copies and extracts from, the Company’s stock ledger, a list of its stockholders, and its other books and records, and the books and records of subsidiaries of the Company, if any, under the circumstances and in the manner provided in Section 220 of the General Corporation Law of Delaware (any and all such rights, and any and all such other rights of the Optionee as may be provided for in Section 220, the “Inspection Rights”). In light of the foregoing, until the first sale of Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act, the Optionee hereby unconditionally and irrevocably waives the Inspection Rights, whether such Inspection Rights would be exercised or pursued directly or indirectly pursuant to Section 220 or otherwise, and covenants and agrees never to directly or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause of action, or other proceeding to pursue or exercise the Inspection Rights. The foregoing waiver shall not affect any rights of a director, in his or her capacity as such, under Section 220. The foregoing waiver shall not apply to any contractual inspection rights of the Optionee under any other written agreement between the Optionee and the Company.

For the avoidance of doubt, an adjustment to the Exercise Price of an Option or SAR that is made in accordance with Section 4(b) shall not be considered a reduction in Exercise Price or “repricing” of such Option or SAR.

(b) Unless otherwise determined by the Committee or otherwise provided in the Award Agreement or in another contractual agreement with a Participant, if within 24 months following a Change of Control in which the acquirer assumes Awards previously granted or substitutes Awards for new awards covering stock of a successor corporation or its parent corporation or any of its Subsidiaries in the manner set forth in Section 8(a) hereof, a Participant’s service relationship is terminated by the Company (or its successor) without Cause, (i) any outstanding Options or SARs then held by such Participant that are unexercisable or otherwise unvested will automatically be deemed exercisable or otherwise vested, as the case may be, as of the date of such termination, and will remain exercisable until the earlier of the expiration of the existing term of such Option or SAR and 90 days following the date of such termination, (ii) all Awards then subject to Performance Conditions then held by such Participant will automatically vest as of the date of such termination, as if such date were the last day of the applicable performance period, at either the target or actual level of performance (as determined by the Committee), and such deemed earned amount will be paid out as soon as practicable following such termination (in cash, securities or other property) or such later date as may be required to comply with Section 409A of the Code, to the extent Section 409A of the Code is or is likely to become applicable to such Participant and (iii) all other outstanding Awards (i.e., other than Options, SARs and Awards subject to Performance Conditions) then held by such Participant that are unexercisable, unvested or still subject to restrictions or forfeiture, will automatically be deemed exercisable and vested and all restrictions and forfeiture provisions related thereto will lapse as of the date of such termination and will be paid out (in cash, securities or other property) as soon as practicable following such date of termination or such later date as may be required to comply with Section 409A of the Code, to the extent Section 409A of the Code is or is likely to become applicable to such Participant.

12

(c) For the purposes of this Section 8, an Award will be considered assumed or substituted if appropriate adjustments are made to the number and kind of shares and exercise prices, if applicable, as the Committee determines will preserve the material terms and conditions of such Award as in effect immediately prior to the Change of Control, including with respect to vesting schedule, intrinsic value of the Award (if any) as of the Change of Control, transferability of shares underlying such Award and that, following the Change of Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change of Control, the consideration (whether stock, cash, or other securities or property) received in the Change of Control by holders of Class A 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 Change of Control is not solely common stock of the successor corporation or its parent corporation, the Committee may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or SAR or upon the payout of another award for each Share subject to such Award, to be solely common stock of the successor corporation or its parent corporation equal in fair market value to the per share consideration received by holders of Class A Common Stock in the Change of Control.

(d) With respect to an Award that constitutes deferred compensation within the meaning of Section 409A of the Code, to the extent Section 409A of the Code is or is likely to become applicable to the Participant holding such Award, payment or settlement of such Award may accelerate upon a Change of Control for purposes of the Plan or any Award Agreement only if such Change of Control also constitutes a “change in ownership”, “change in effective control” or “change in the ownership of a substantial portion of the Company’s assets” as defined under Section 409A of the Code (it being understood that vesting of the Award may accelerate upon a Change of Control, even if payment or settlement of the Award may not accelerate pursuant to this sentence.

SECTION 9. General Provisions. (a) Nontransferability. During the Participant’s lifetime, each Award (and any rights and obligations thereunder) shall be exercisable only by the Participant, or, if permissible under Applicable Law, by the Participant’s legal guardian or representative, and no Award (or any rights and obligations thereunder) may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution, and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate; provided that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance. All terms and conditions of the Plan and the applicable Award Agreements shall be binding upon any permitted successors and assigns.

(b) No Rights to Awards. No Participant or other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated.

13

(c) Share Certificates. All certificates for Shares or other securities of the Company or any Affiliate delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement or the rules, regulations and other requirements of the SEC, the Applicable Exchange and any Applicable Law and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. Notwithstanding any other provision of the Plan, unless otherwise determined by the Committee or required by any Applicable Law, the Company shall not deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares shall be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan administrator).

(d) Withholding. A Participant may be required to pay to the Company or any Affiliate, and the Company or any Affiliate shall have the right and is hereby authorized to withhold from any Award, from any payment due or transfer made under any Award or under the Plan or from any compensation or other amount owing to a Participant, the amount (in cash, Shares, other securities, other Awards or other property) of any applicable withholding taxes in respect of an Award, its exercise or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Committee or the Company to satisfy all obligations for the payment of such taxes, except to the extent such withholding would result in penalties under Section 409A of the Code. Without limiting the generality of the foregoing, subject to the Committee’s prior approval, a Participant may satisfy, in whole or in part, such withholding liability by having the Company withhold from the number of Shares otherwise issuable pursuant to the Award, a number of Shares having a Fair Market Value equal to such withholding liability.

(e) Section 409A. (i) It is intended that the provisions of the Plan comply with Section 409A of the Code, and all provisions of the Plan shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A of the Code.

(ii) No Participant or the creditors or beneficiaries of a Participant shall have the right to subject any deferred compensation (within the meaning of Section 409A of the Code) payable under the Plan to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted under Section 409A of the Code, any deferred compensation (within the meaning of Section 409A of the Code) payable to any Participant or for the benefit of any Participant under the Plan may not be reduced by, or offset against, any amount owing by any such Participant to the Company or any of its Affiliates.

(iii) If, at the time of a Participant’s separation from service (within the meaning of Section 409A of the Code), (A) such Participant shall be a specified employee (within the meaning of Section 409A of the Code and using the identification methodology selected by the Company from time to time) and (B) the Company shall make a good faith determination that an amount payable pursuant to an Award constitutes deferred compensation (within the meaning of Section 409A of the Code) the payment of which is required to be delayed pursuant to the six-month delay rule set forth in Section 409A of the Code in order to avoid taxes or penalties under Section 409A of the Code, then the Company shall not pay such amount on the otherwise scheduled payment date but shall instead pay it on the first business day after such six-month period. Such amount shall be paid without interest, unless otherwise

14

determined by the Committee, in its sole discretion, or as otherwise provided in any applicable employment agreement between the Company and the relevant Participant. For purposes of Section 409A of the Code, any right to a series of installment payments under any Award shall be treated as a right to a series of separate payments.

(iv) Notwithstanding any provision of the Plan to the contrary, in light of the uncertainty with respect to the proper application of Section 409A of the Code, the Company reserves the right to make amendments to any Award as the Company deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code. In any case, a Participant shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on such Participant or for such Participant’s account in connection with an Award (including any taxes and penalties under Section 409A of the Code), and neither the Company nor any of its Affiliates shall have any obligation to indemnify or otherwise hold such Participant harmless from any or all of such taxes or penalties.

(f) Award Agreements. Each Award hereunder shall be evidenced by an Award Agreement, which shall be delivered to the Participant and shall specify the terms and conditions of the Award and any rules applicable thereto.

(g) No Limit on Other Compensation Arrangements. Nothing contained in the Plan shall prevent the Company or any Affiliate from adopting or continuing in effect other compensation arrangements (including other equity-based awards and cash incentive awards), and such arrangements may be either generally applicable or applicable only in specific cases.

(h) No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained as a director, officer, employee or consultant of or to the Company or any Affiliate, nor shall it be construed as giving a Participant any rights to continued service on the Board. Further, the Company or an Affiliate may at any time dismiss a Participant from employment or discontinue any directorship or consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Award Agreement.

(i) No Rights as Stockholder. No Participant or holder or beneficiary of any Award shall have any rights as a stockholder with respect to any Shares to be distributed under the Plan until he or she has become the holder of such Shares. In connection with each grant of Restricted Shares, except as provided in the applicable Award Agreement, the Participant shall be entitled to the rights of a stockholder (including the right to vote) in respect of such Restricted Shares. Except as otherwise provided in Section 4(b) or the applicable Award Agreement, no adjustments shall be made for dividends or distributions on (whether ordinary or extraordinary, and whether in cash, Shares, other securities or other property), or other events relating to, Shares subject to an Award for which the record date is prior to the date such Shares are delivered.

(j) Governing Law. The validity, construction and effect of the Plan and any rules and regulations relating to the Plan and any Award Agreement shall be determined in accordance with the laws of the State of Delaware, without giving effect to the conflict of laws provisions thereof.

15

(k) Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to such law, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken as to such jurisdiction, Person or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

(l) Other Laws; Restrictions on Transfer of Shares. The Committee may refuse to issue or transfer any Shares or other consideration under an Award if it determines that the issuance or transfer of such Shares or such other consideration might violate any Applicable Law or entitle the Company to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary.

(m) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate, on one hand, and a Participant or any other Person, on the other. To the extent that any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company or such Affiliate.

(n) No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be canceled, terminated or otherwise eliminated.

(o) Headings and Construction. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof. Whenever the words “include”, “includes” or “including” are used in the Plan, they shall be deemed to be followed by the words “but not limited to”, and the word “or” shall not be deemed to be exclusive.

SECTION 10. Amendment and Termination. (a) Amendments to the Plan. Subject to any Applicable Law, the Plan may be amended, modified or terminated by the Board without the approval of the stockholders of the Company, except that stockholder approval shall be required for any amendment that would (i) increase the Share Limit or the ISO Limit (except for increases pursuant to an adjustment under Section 4(b)) or an increase under Section 4(a), (ii) expand the class of employees or other individuals eligible to participate in the Plan, (iii) extend the Expiration Date or (iv) result in any amendment, cancellation or action described in Section 7(c) being permitted without the approval of the Company’s stockholders. No amendment, modification or termination of the Plan may, without the consent of the Participant to whom any Award shall previously have been granted, materially and adversely affect the rights of such Participant (or his or her transferee) under such Award, unless otherwise provided in the applicable Award Agreement.

16

(b) Amendments to Awards. The Committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate any Award previously granted, prospectively or retroactively; provided, however, that, except as set forth in the Plan, unless otherwise provided in the applicable Award Agreement, any such waiver, amendment, alteration, suspension, discontinuance, cancelation or termination that would materially and adversely affect the rights of any Participant (or his or her transferee) under any Award previously granted shall not to that extent be effective without the consent of the applicable Participant or transferee.

SECTION 11. Term of the Plan. The Plan shall be effective as of the date of its adoption by the Board and approval by the Company’s stockholders (the “Effective Date”). No Award shall be granted under the Plan after the tenth anniversary of the Effective Date (the “Expiration Date”). Unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award granted hereunder, and the authority of the Board or the Committee to amend, alter, adjust, suspend, discontinue or terminate any such Award or to waive any conditions or rights under any such Award, shall nevertheless continue thereafter.

3

state or other regulatory agencies, (ix) severance pay, and (x) all other cash bonuses not mentioned above (such as referral bonuses, peer bonuses, and sign-on bonuses). Compensation will be calculated before deduction of any income or employment tax withholdings. Compensation will include the net impact of any current-period payments/deductions to correct for prior-period payroll errors (unless the Administrator, in its sole discretion, elects to give such corrections retroactive effect for purposes of this Plan). The Administrator, in its discretion, may establish a different definition of Compensation for an Offering, which for the Section 423 Component will apply on a uniform and nondiscriminatory basis.

An Affiliate that is disregarded for U.S. federal income tax purposes in respect of a Designated Company participating in the 423 Component will automatically be a Designated Company participating in the 423 Component. An Affiliate that is disregarded for U.S. federal income tax purposes in respect of a Designated Company participating in the Non-423 Component may be excluded from participating in the Plan by the Administrator or may be assigned by the Administrator to an Offering within the Non-423 Component that is separate from the Offering to which the Administrator assigns the Designated Company with respect to which it is disregarded.

(n) “Director” means any non-employee member of the Board, but solely in his or her capacity as such a member of the Board.

(o) “Eligible Employee” means any individual who is an employee providing services to the Company or a Designated Company. For purposes of the Plan, the employment relationship will be treated as continuing intact while the individual is on military leave, sick leave or other leave of absence that the Employer approves or is otherwise legally protected under Applicable Laws. Where the period of leave exceeds three months and the individual’s right to reemployment is not guaranteed either by Applicable Laws or by contract, the employment relationship will be deemed to have terminated three months and one day following the commencement of such leave or such other period specified under the Treasury Regulations. The Administrator may, in its discretion, from time to time prior to an Offering Start Date for all options to be granted on such Offering Start Date relating to an Offering, determine (on a uniform and nondiscriminatory basis or as otherwise permitted by Section 1.423-2 of the Treasury Regulations) that the definition of Eligible Employee will or will not include an individual if he or she (i) has not completed at least two years of service since his or her last hire date (or such lesser period of time as may be determined by the Administrator in its discretion), (ii) customarily works not more than 20 hours per week (or such lesser period of time as may be

4

determined by the Administrator in its discretion), (iii) customarily works not more than five months per calendar year (or such lesser period of time as may be determined by the Administrator in its discretion) or (iv) is a highly compensated employee within the meaning of Section 414(q) of the Code (or such higher threshold as may be determined by the Administrator in its discretion); provided, however, that the exclusion is applied with respect to each Offering in an identical manner to all highly compensated individuals of the Employer whose Eligible Employees are participating in that Offering. Each exclusion will be applied with respect to an Offering in a manner complying with Section 1.423-2(e) of the Treasury Regulations. Notwithstanding the foregoing, (1) for purposes of any Offering under the 423 Component, the Administrator may determine that the definition of Eligible Employee will not include employees who are citizens or residents of a foreign jurisdiction (without regard to whether they are also citizens of the United States or resident aliens) if (A) the grant of an option under the Plan or such Offering to a citizen or resident of the foreign jurisdiction is prohibited under the laws of such jurisdiction or (B) compliance with the laws of the foreign jurisdiction would cause the Plan or such Offering to violate the requirements of Section 423; and (2) for purposes of any Offering under the Non-423 Component, the Administrator may alter the definition of Eligible Employee in its discretion, provided that anyone included in the definition must be a Person to whom the issuance of stock may be registered on Form S-8 under the U.S. Securities Act of 1933, as amended.

(p) “Employer” means the employer of the applicable Eligible Employee(s).

(q) “Exchange Act” means the Securities Exchange Act of 1934, as amended from time to time, or any successor statute thereto, and the regulations promulgated thereunder.

(s) “New Purchase Date” means a new Purchase Date if the Administrator shortens any Offering Period then in progress.

(t) “Offering” means an offer under the Plan of an option that may be exercised during an Offering Period as further described in Section 5 hereof. For purposes of the Plan, the Administrator may designate separate Offerings under the Plan (the terms of which need not be identical) in which Eligible Employees of one or more Employers will participate, even if the dates of the applicable Offering Periods of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. To the extent permitted by Section 1.423-2(a)(1) of the Treasury Regulations, the terms of each Offering need not be identical; provided, however, that the terms of the Plan and an Offering together satisfy Sections 1.423-2(a)(2) and (a)(3) of the Treasury Regulations.

5

(u) “Offering Periods” means each period during which an option granted pursuant to the Plan is outstanding. The duration and timing of Offering Periods may be changed pursuant to Sections 5 and 20 hereof.

(aa) “Purchase Date” means the last Trading Day of the Purchase Period.

3. Share Limitations; Certain Provisions Relating to Common Stock. (a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of shares of Common Stock that will be made available for sale under the Plan shall be 2,300,000 shares of Common Stock.

(b) If any option granted under the Plan terminates without having been exercised in full, the shares of Common Stock not purchased under such option will remain available for issuance under the Plan.

(c) Until shares of Common Stock are issued under the Plan (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 of Common Stock, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares of Common Stock.

4. Eligibility. (a) Generally. Any Eligible Employee on a given Offering Start Date for an Offering Period will be eligible to participate in the Plan during such Offering Period, subject to the requirements of Section 6 hereof.

(b) Limitations. Notwithstanding any provisions of the Plan to the contrary, no Eligible Employee will be granted an option under the 423 Component of the Plan (i) 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 Section 424(d) of the Code) would own capital stock of the Company or any Affiliate and/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 any Affiliate or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Affiliate accrues at a rate that 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 Section 423 of the Code and the Treasury Regulations thereunder.

(c) Equal Rights and Privileges. Notwithstanding any provisions of the Plan to the contrary, each Eligible Employee granted an option under the 423 Component of the Plan shall have the same rights and privileges with respect to such option to the extent required under Section 423(b)(5) of the Code and Section 1.423-2(f) of the Treasury Regulations.

5. Offering Periods. (a) The Plan will be implemented by one or more Offering Periods. Offerings may be consecutive or overlapping as determined by the Administrator. The duration and timing of Offering Periods may be changed pursuant to this Section 5 and Section 20 hereof. The Administrator will have the power to establish the duration of the first Offering Period and change the duration of Offering Periods (including the commencement dates thereof) with respect to future Offerings. No Offering Period may be more than 27 months in duration.

7

(b) Prior to the Offering Start Date of an Offering Period, the Administrator will establish the maximum number of shares of Common Stock that an Eligible Employee will be permitted to purchase during each Purchase Period during such Offering Period.

6. Participation. An Eligible Employee may participate in the Plan pursuant to Section 4 hereof 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 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 (i) the applicable Offering Start Date as determined by the Administrator, in its sole discretion, or (ii) with respect to the first Offering Period, no later than 30 days following the Offering Start Date.

7. Contributions. (a) At the time a Participant enrolls in the Plan pursuant to Section 6 hereof, 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 eligible pay day during the Offering Period equal to a whole percentage (and subject to any limit as may be set by the Administrator from time to time) of the Compensation that he or she receives on the pay day. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement or otherwise made available by the Administrator prior to each Purchase Date of each Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 11 hereof.

(b) In the event Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the first eligible pay day following the Offering Start Date and will end on the last eligible pay day on or prior to the last Purchase Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 11 hereof; provided, however, that for the first Offering Period, payroll deductions will not commence until such date determined by the Administrator, in its sole discretion. Notwithstanding the foregoing, for administrative convenience, the Administrator (by announcement prior to the first affected Offering Period) may determine that contributions with respect to an eligible pay day occurring on a Purchase Date (or during a period of up to five business days prior to a Purchase Date) shall be applied instead to the subsequent Purchase Period or Offering Period.

(c) All Contributions made for a Participant will be credited to his or her account under the 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.

(d) A Participant may discontinue his or her participation in the Plan as provided under Section 11 hereof. Unless otherwise determined by the Administrator, during a Purchase Period, a Participant may not increase or decrease the rate of his or her Contributions.

8

The Administrator may, in its sole discretion, provide for, or amend the nature and/or number of, Contribution rate changes that may be made by Participants during any Offering Period or Purchase Period and may establish other conditions, limitations or procedures as it deems appropriate for Plan administration.

(e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 4(c) hereof, a Participant’s Contributions may be decreased by the Administrator to 0% at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 4(c) hereof, Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 11 hereof.

(f) Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Participants to participate in the Plan via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted (or the remittance of payroll deductions by a Designated Company to the Company is not feasible) under Applicable Laws, (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code or (iii) the Participants are participating in the Non-423 Component.

(g) 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 the Plan is disposed of (or any other time that a taxable event related to the 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 the 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 satisfy applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to 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 utilize any other method of withholding the Company deems appropriate (such as requiring a market sale of shares received under the Plan).

8. Grant of Option. On the Offering Start Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Purchase 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 Purchase Date and retained in the Eligible Employee’s account as of the Purchase Date by the applicable Purchase Price; provided, however, that such purchase will be subject to the limitations set forth in Sections 3, 4(c), 5(b) and 6 hereof. The Eligible Employee may accept the grant of such option by electing to participate in the Plan in accordance with the requirements of Section 6 hereof. Exercise of the option will occur as provided in Section 9 hereof, unless the Participant has withdrawn pursuant to Section 11 hereof. The option will expire on the last day of the Offering Period.

9

9. Exercise of Option. (a) Unless a Participant withdraws from the Plan as provided in Section 11 hereof, his or her option for the purchase of shares of Common Stock will be exercised automatically on each Purchase Date, and the maximum number of full shares 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, unless otherwise determined by the Administrator. Any Contributions accumulated in a Participant’s account at the end of an Offering Period, which are not sufficient to purchase a full share will either, as the Administrator shall determine, (i) be refunded to the Participant promptly following the end of such Offering Period, or (ii) be retained in the Participant’s account for the subsequent Purchase Period or Offering Period, subject to earlier withdrawal by the Participant as provided in Section 11 hereof. During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her.

(b) If the Administrator determines that, on a given Purchase Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed the number of shares of Common Stock that were available for sale under the Plan on such Purchase Date, the Administrator may, in its sole discretion, provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Purchase Date 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 Purchase Date, and either (i) continue all Offering Periods then in effect or (ii) terminate any or all Offering Periods then in effect pursuant to Section 20 hereof.

10. Delivery. As soon as reasonably practicable after each Purchase Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant (or, if required by Applicable Laws, to the Participant and his or her spouse) of the shares 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 be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying 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 the Plan until such shares have been purchased and delivered to the Participant as provided in this Section 10.

11. Withdrawal. (a) 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 the Plan at any time by (i) 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 or (ii) following an electronic or other withdrawal procedure determined by the Administrator. Notwithstanding the foregoing, the Administrator may establish a reasonable deadline (such as two weeks prior to the Purchase Date) by which time withdrawals must be submitted in order for the Participant to avoid automatic exercise of his or her option on the Purchase Date (unless the Administrator in its sole discretion elects to process the withdrawal more quickly or as may be required by Applicable Laws). All of the Participant’s Contributions

10

credited to his or her account and not applied to the purchase of shares of Common Stock will be paid to such Participant promptly 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 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 the Plan in accordance with the provisions of Section 6 hereof.

(b) A Participant’s withdrawal from an Offering Period will not have any effect on 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 Purchase Period from which the Participant withdraws.

12. Termination and Transfer of Employment. (a) Upon a Participant’s ceasing to be an Eligible Employee, for any reason (including by reason of the Participant’s Employer ceasing to be a Designated Company or by reason of Participant’s transfer of employment to an Affiliate that is not a Designated Company), he or she will be deemed to have elected to withdraw from the 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 the Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15 hereof, and such Participant’s option will be automatically terminated.

(b) Unless otherwise provided by the Administrator, 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 the Plan; provided, however, that 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 Section 423 of the Code, unless otherwise provided by the Administrator. If a Participant transfers from an Offering under the Non-423 Component to an Offering under the 423 Component, the exercise of the option will remain non-qualified under the Non-423 Component. The Administrator may establish additional or different rules governing employment transfers.

13. Interest. No interest will accrue on the Contributions of a participant in the 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 to all Participants in the relevant Offering under the 423 Component.

14. Administration. (a) The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. Nothing in such appointment shall preclude the Board from itself taking any administrative action set forth herein, except where such action is required by Applicable Laws to be taken by a Committee. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to delegate administrative duties to any of the Company’s employees, to designate separate Offerings under the Plan, to designate Affiliates as participating in the 423 Component or Non-423 Component, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems

11

necessary for the administration of the Plan (including, without limitation, to adopt such rules, procedures, sub-plans and appendices to the subscription agreement as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which rules, procedures, sub-plans and appendices may take precedence over other provisions of this Plan, with the exception of Section 3(a) hereof, but unless otherwise superseded by the terms of such rules, procedures, sub-plans and appendices, the provisions of this Plan will govern the operation of such rules, procedures, sub-plans or appendices). Unless otherwise determined by the Administrator, the Eligible Employees eligible to participate in each sub-plan will participate in a separate Offering or in the Non-423 Component. 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 the Plan (including, without limitation, in forms other than payroll deductions and, further, including making any adjustments to correctly reflect a Participant’s elected percentage of payroll deductions or other payments), 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, with respect to the 423 Component, to the extent permitted by Section 1.423-2(f) of the Treasury Regulations, the terms of an option granted under the 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 the 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.

(b) The Administrator may delegate, on such terms and conditions as it determines in its sole and plenary discretion, to (i) the Chief Executive Officer of the Company who also serves as a member of the Board or (ii) one or more senior officers of the Company, in each case, any or all of its authority under the Plan and all necessary and appropriate decisions and determinations with respect thereto.

15. Designation of Beneficiary. (a) If permitted by the Administrator and subject to Applicable Laws, a Participant may file a designation of a beneficiary who is to receive any shares of Common Stock and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to a Purchase Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

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

12

(c) All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding Sections 15(a) and (b) hereof, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by Section 1.423-2(f) of the Treasury Regulations.

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 the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) 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 11 hereof.

17. Use of Funds. The Company may use all Contributions received or held by it under the 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 the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party. Until shares of Common Stock are issued, Participants will have only the rights of an unsecured creditor with respect to such shares.

18. Reports. Individual accounts will be maintained for each Participant in the 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.

19. Adjustments, Dissolution, Liquidation, or Change of Control. (a) Adjustments. In the event of any extraordinary dividend or other extraordinary 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, repurchase, exchange of Common Stock or other securities of the Company or other change in the corporate structure of the Company affecting the Common Stock, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, shall, in such manner as it shall deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Section 3 hereof and established pursuant to Sections 5(b) and 8 hereof.

13

(b) Dissolution or Liquidation. In the event a proposed dissolution or liquidation, Change of Control or other similar transaction of the Company receives all requisite approvals under Applicable Laws, any Offering Period then in progress will be shortened by setting a New Purchase Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, Change of Control or other similar transaction, as applicable, unless provided otherwise by the Administrator. The New Purchase Date will be before the date of the Company’s proposed dissolution or liquidation, Change of Control or other similar transaction, as applicable. The Administrator will notify each Participant in writing or electronically, prior to the New Purchase Date, that the Purchase Date for the Participant’s option has been changed to the New Purchase Date and that the Participant’s option will be exercised automatically on the New Purchase Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 11 hereof.

20. Amendment or Termination. (a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the 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 Purchase 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 19 hereof). 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 13 hereof) as soon as administratively practicable.

(b) Without stockholder consent and without limiting Section 14(a) or Section 20(a) hereof, the Administrator will be entitled to change the Offering Periods or Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio 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 and/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 the Plan.

(c) In the event the Administrator determines that the ongoing operation of the 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 the Plan to reduce or eliminate such accounting consequence including, but not limited to:

(i) amending the 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;

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

14

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

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

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

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

21. Notices. All notices or other communications by a Participant to the Company under or in connection with the 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.

22. Conditions Upon Issuance of Shares. (a) 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 all Applicable Law, and will be further subject to the approval of counsel for the Company with respect to such compliance.

(b) 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 by any of the aforementioned applicable provisions of law.

23. Section 409A. Options granted under the 423 Component of the Plan are exempt from the application of Section 409A and any ambiguities herein will be interpreted to so be exempt from Section 409A. Options granted under the Non-423 Component to U.S. taxpayers are intended to be exempt from the application of Section 409A under the short-term deferral exception or compliant with Section 409A and any ambiguities will be construed and interpreted in accordance with such intent. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the 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 the 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, a Participant will be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on such Participant or for such Participant’s account in connection with option to purchase Common Stock under the Plan (including any taxes and penalties under Section 409A), and neither the Company nor any of its Affiliates will have any obligation to indemnify or otherwise hold such Participant harmless from any or all such taxes or penalties. The Company makes no representation that the option to purchase Common Stock under the Plan is compliant with Section 409A.

15

24. Term of Plan. The Plan will become effective upon the later to occur of (a) its adoption by the Board and (b) immediately prior to the effective date of the registration statement on Form S-1 filed with the U.S. Securities and Exchange Commission for the initial public offering of Common Stock (such later date, the “Effective Date”). It will continue in effect for a term of 20 years, unless terminated earlier under Section 20 hereof.

25. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within 12 months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. For the avoidance of doubt, failure to obtain a stockholder approval required by any non-U.S. jurisdiction will not impair the validity of the Plan in any other jurisdiction.

26. Governing Law. The validity, construction and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware, without giving effect to the conflict of laws provisions thereof.

27. Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction or as to any Person, or would disqualify the Plan under any law deemed applicable by the Administrator, such provision shall be construed or deemed amended to conform to the Applicable Laws, or if it cannot be construed or deemed amended without, in the determination of the Administrator, materially altering the intent of the Plan, such provision shall be construed or deemed stricken as to such jurisdiction or Person and the remainder of the Plan shall remain in full force and effect.

28. No Right to Continued Employment. Participation in the Plan by a Participant will not be construed as giving a Participant the right to be retained as an employee of the Company or an Affiliate, as applicable. Further, the Company or an Affiliate may dismiss a Participant from employment at any time, free from any liability or any claim under the Plan, unless otherwise required pursuant to Applicable Laws.

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

30. Headings and Construction. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof. Whenever the words “include”, “includes” or “including” are used in the Plan, they shall be deemed to be followed by the words “but not limited to”, and the word “or” shall not be deemed to be exclusive. Pronouns and other words of gender shall be read as gender-neutral. Words importing the plural shall include the singular and the singular shall include the plural. For the avoidance of doubt, where a term of the Plan is required by Section 423 of the Code, such term need not apply to the Non-423 Component of the Plan as determined in the sole discretion of the Administrator.

16
