Exhibit 10.1

TRANSMEDICS GROUP, INC.

AMENDEDAND RESTATED 2019 STOCK INCENTIVE PLAN

(as amended through May 25, 2023)

1. DEFINED TERMS

Exhibit A, which is incorporated by reference, defines certain terms used in the Plan and sets forth operational rules related to those terms.

2. PURPOSE

The Plan is intended to advance the interests of the Company by providing for the grant to Participants of Stock and Stock-based Awards. The purposes of the Plan are to attract, retain, and reward key Employees and Directors of, and consultants and advisors to, the Company and its subsidiaries, to incentivize them to generate stockholder value, to enable them to participate in the growth of the Company and to align their interests with the interests of the Company’s stockholders.

3. ADMINISTRATION

The Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express provisions of the Plan, to administer and interpret the Plan and any Award; to determine eligibility for and grant Awards; to determine the exercise price, base value from which appreciation is measured, or purchase price, if any, applicable to any Award; to determine, modify or waive the terms and conditions of any Award; to determine the form of settlement of Awards (whether in cash, shares of Stock, other Awards, or other property); to prescribe forms, rules and procedures relating to the Plan and Awards; and to otherwise do all things necessary or desirable to carry out the purposes of the Plan or any Award. Determinations of the Administrator made with respect to the Plan or any Award are conclusive and bind all persons.

4. LIMITSON AWARDS UNDERTHE PLAN

(a) Number of Shares. Subject to adjustment as provided in Section 7(b), the number of shares of Stock that may be issued in satisfaction of Awards under the Plan is (i) 4,275,090 shares of Stock (inclusive of 2,874,549 shares of Stock subject to Awards outstanding under the Plan as of March 31, 2023), plus (ii) the number of shares of Stock underlying awards under the Prior Plan (which will not exceed 516,452 shares) that on or after March 31, 2023 expire or are terminated, surrendered or cancelled without the delivery of shares of Stock, are forfeited to, or repurchased by, the Company, or otherwise become available again for grant under the Prior Plan, in each case, in accordance with its terms (collectively, the “Share Pool”). Up to 4,275,090 of the shares of Stock from the Share Pool may be issued in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number of, ISOs be granted under the Plan. For purposes of this Section 4(a), the number of shares of Stock issued in satisfaction of Awards will be determined (i) by including shares of Stock withheld by the Company in payment of the exercise price or purchase price of the Award or in satisfaction of tax withholding requirements with respect to the Award, (ii) by including the full number of shares covered by a SAR any portion of which is settled in Stock (and not only the number of shares of Stock delivered in settlement), and (iii) by excluding any shares of Stock underlying Awards settled in cash or that expire, become unexercisable, terminate or are forfeited to or repurchased by the Company without the issuance of Stock. For the avoidance of doubt, the number of shares of Stock available for delivery under the Plan will not be increased by any shares of Stock delivered under the Plan that are subsequently repurchased using proceeds directly attributable to Stock Option exercises. The limits set forth in this Section 4(a) will be construed to comply with the applicable requirements of Section 422.

(b) Substitute Awards. The Administrator may grant Substitute Awards under the Plan. To the extent consistent with the requirements of Section 422 and the regulations thereunder and other applicable legal requirements (including applicable stock exchange requirements), shares of Stock issued in respect of Substitute Awards will be in addition to and will not reduce the Share Pool, but, notwithstanding anything in Section 4(a) to

the contrary, if any Substitute Award is settled in cash or expires, becomes unexercisable, terminates or is forfeited to or repurchased by the Company, in each case, without the issuance (or retention (in the case of Restricted Stock)) of Stock, the shares of Stock previously subject to such Award will not increase the Share Pool or otherwise be available for future issuance under the Plan. .

(c) Type of Shares. The shares of Stock issued under the Plan may be shares of authorized but unissued Stock, treasury Stock, or Stock acquired in an open-market transaction. No fractional shares of Stock will be issued under the Plan.

(d) Director Limits. Notwithstanding the foregoing limits, the aggregate value of all compensation granted or paid to any Director with respect to the calendar year in which such Director is first elected or appointed to the Board, including Awards granted under the Plan and cash fees or other compensation paid by the Company to such Director outside of the Plan, in each case, for his or her services as a Director during such calendar year, may not exceed $1,000,000 in the aggregate, calculating the value of any Awards based on the grant date fair value in accordance with the Accounting Rules and assuming maximum payout levels. In addition, the aggregate value of all compensation granted or paid to any Director with respect to any other calendar year, including Awards granted under the Plan and cash fees or other compensation paid by the Company to such Director outside of the Plan, in each case, for his or her services as a Director during such calendar year, may not exceed $750,000 in the aggregate, calculating the value of any Awards based on the grant date fair value in accordance with the Accounting Rules and assuming maximum payout levels. The Administrator may make exceptions to this limit for individual Directors in extraordinary circumstances, as the Administrator may determine in its discretion, provided that the Director receiving such additional compensation may not participate in the decision to award such compensation.

5. ELIGIBILITYAND PARTICIPATION

The Administrator will select Participants from among key Employees and Directors of, and consultants and advisors to, the Company and its subsidiaries. Eligibility for ISOs is limited to employees of the Company or of a “parent corporation” or “subsidiary corporation” of the Company as those terms are defined in Section 424 of the Code. Eligibility for NSOs and SARs is limited to individuals who are providing direct services on the date of grant of the Award to the Company or to a subsidiary of the Company that would be described in the first sentence of Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations.

6. RULES APPLICABLETO AWARDS

(a) All Awards.

(1) Award Provisions. The Administrator will determine the terms and conditions of all Awards, subject to the limitations provided herein. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award, the Participant will be deemed to have agreed to the terms and conditions of the Award and the Plan. Notwithstanding any provision of the Plan to the contrary, Substitute Awards may contain terms and conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator.

(2) Term of Plan. No Awards may be made after June 1, 2033, but previously granted Awards may continue beyond that date in accordance with their terms.

(3) Transferability. Neither ISOs nor, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), other Awards may be transferred other than by will or by the laws of descent and distribution. During a Participant’s lifetime, ISOs and, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), SARs and NSOs may be exercised only by the Participant. The Administrator may permit the transfer of Awards other than ISOs, subject to applicable securities and other laws and such terms and conditions as the Administrator may determine.

(4) Vesting; Exercisability. The Administrator will determine the time or times at which an Award vests or becomes exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable.

-2-

Without limiting the foregoing, the Administrator may at any time accelerate the vesting and/or exercisability of an Award (or any portion thereof), regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration. Unless the Administrator expressly provides otherwise, however, the following rules will apply if a Participant’s Employment ceases:

(A) Except as provided in (B) and (C) below, immediately upon the cessation of the Participant’s Employment, each Stock Option and SAR (or portion thereof) that is then held by the Participant or by the Participant’s permitted transferees, if any, will cease to be exercisable and will terminate, and each other Award that is then held by the Participant or by the Participant’s permitted transferees, if any, to the extent not then vested, will be forfeited.

(B) Subject to (C) and (D) below, each vested and unexercised Stock Option and SAR (or portion thereof) held by the Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of three months following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate.

(C) Subject to (D) below, each vested and unexercised Stock Option and SAR (or portion thereof) held by a Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment due to his or her death, to the extent then exercisable, will remain exercisable for the lesser of (i) the one-year period ending on the first anniversary of the Participant’s death or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate.

(D) All Awards (whether or not vested or exercisable) held by a Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment will immediately terminate upon such cessation of Employment if the termination is for Cause or occurs in circumstances that in the determination of the Administrator would have constituted grounds for the Participant’s Employment to be terminated for Cause (in each case, without regard to the lapsing of any required notice or cure periods in connection therewith).

(5) Recovery of Compensation. The Administrator may provide in any case that any outstanding Award (whether or not vested or exercisable), the proceeds from the exercise or disposition of any Award or Stock acquired under any Award, and any other amounts received in respect of any Award or Stock acquired under any Award will be subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant to whom the Award was granted is not in compliance with any provision of the Plan or any applicable Award, any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention assignment, or other restrictive covenant by which he or she is bound. Each Award shall be subject to any policy of the Company or any of its subsidiaries that provides for forfeiture, disgorgement or clawback with respect to incentive compensation that includes Awards under the Plan and shall be subject to forfeiture and disgorgement to the extent required by law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Exchange Act. Each Participant, by accepting or being deemed to have accepted an Award under the Plan, agrees (or will be deemed to have agreed) to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to cooperate fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 6(a)(5). Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 6(a)(5).

(6) Taxes. The issuance, delivery, vesting, and retention of Stock, cash or other property under an Award are conditioned upon the full satisfaction by the Participant of all tax and other withholding requirements with respect to the Award. The Administrator will prescribe such rules for the withholding of taxes and other amounts with respect to any Award as it deems necessary. The Administrator may hold back shares of Stock from an Award or permit a Participant to tender previously-owned shares of Stock in satisfaction of tax or other withholding requirements (but not in excess of the maximum withholding amount consistent with the Award being subject to equity accounting treatment under the Accounting Rules). Any amounts withheld pursuant to this Section 6(a)(6) will be treated as though such payment had been made directly to the Participant.

-3-

(7) Dividend Equivalents. The Administrator may provide for the payment of amounts, on such terms and subject to conditions established by the Administrator, in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award (other than an Option or a SAR, except as contemplated by Section 7 of the Plan), whether or not the holder of such Award is otherwise entitled to share in the actual dividend or distribution in respect of such Award; provided, however, that dividends or dividend equivalents relating to an Award that, at the dividend payment date, remains subject to a risk of forfeiture (whether service-based or performance-based) shall be subject to the same risk of forfeiture as applies to the underlying Award and in no event shall such dividends or dividend equivalents be paid unless and until such Award vests and becomes payable. Subject to Section 6(a)(10), any entitlement to dividend equivalents or similar entitlements will be established and administered either consistent with an exemption from, or in compliance with, the applicable requirements of Section 409A. Dividends and dividend equivalent amounts payable in respect of Awards that are subject to restrictions may be subject to such limitations or restrictions as the Administrator may impose.

(8) Rights Limited. Nothing in the Plan or any Award will be construed as giving any person the right to be granted an Award or to continued employment or service with the Company or any of its subsidiaries, or any rights as a stockholder except as to shares of Stock actually issued under the Plan. The loss of existing or potential profit in any Award will not constitute an element of damages in the event of a termination of a Participant’s Employment for any reason, even if the termination is in violation of an obligation of the Company or any of its subsidiaries to the Participant.

(9) Coordination with Other Plans. Awards under the Plan may be granted in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or programs of the Company or any of its subsidiaries. For example, but without limiting the generality of the foregoing, awards under other compensatory plans or programs of the Company or any of its subsidiaries may be settled in shares of Stock (including, without limitation, Unrestricted Stock) under the Plan if the Administrator so determines, in which case the shares will be treated as issued under the Plan (and will reduce the Share Pool in accordance with the rules set forth in Section 4).

(10) Section 409A.

(A) Without limiting the generality of Section 11(b), each Award will contain such terms as the Administrator determines and will be construed and administered such that the Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements.

(B) If a Participant is determined on the date of the Participant’s termination of Employment to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any payment that is considered nonqualified deferred compensation under Section 409A, to the extent applicable, payable on account of a “separation from service”, such payment will be made or provided on the date that is the earlier of (i) the first business day following the expiration of the six-month period measured from the date of such “separation from service” and (ii) the date of the Participant’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 6(a)(10)(B) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid on the first business day following the expiration of the Delay Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award agreement.

(C) With regard to any payment considered to be nonqualified deferred compensation under Section 409A, to the extent applicable, that is payable upon a change in control of the Company or other similar event, to the extent required to avoid the imposition of any additional tax, interest, or penalty under Section 409A, no amount will be payable unless such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations.

(D) For purposes of Section 409A, each payment made under the Plan will be treated as a separate payment.

-4-

(b) Stock Options and SARs.

(1) Time and Manner of Exercise. Unless the Administrator expressly provides otherwise, no Stock Option or SAR will be considered to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by any payment required under the Award. Any attempt to exercise a Stock Option or SAR by any person other than the Participant will not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so.

(2) Exercise Price. The exercise price (or the base value from which appreciation is to be measured) per share of each Award requiring exercise must be no less than 100% (in the case of an ISO granted to a 10-percent stockholder within the meaning of Section 422(b)(6) of the Code, 110%) of the Fair Market Value of a share of Stock, determined as of the date of grant, or such higher amount as the Administrator may determine in connection with the grant.

(3) Payment of Exercise Price. Where the exercise of an Award (or portion thereof) is to be accompanied by a payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the Administrator and if legally permissible, (i) through the delivery of previously acquired unrestricted shares of Stock, or the withholding of unrestricted shares of Stock otherwise issuable upon exercise, in either case, that have a Fair Market Value equal to the exercise price; (ii) through a broker-assisted cashless exercise program acceptable to the Administrator; (iii) by other means acceptable to the Administrator; or (iv) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise price under clause (i) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe.

(4) Maximum Term. The maximum term of Stock Options and SARs must not exceed 10 years from the date of grant (or five years from the date of grant in the case of an ISO granted to a 10-percent stockholder described in Section 6(b)(2)).

(5) Repricing. Except in connection with a corporate transaction involving the Company (which term includes, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split up, spin-off, combination or exchange of shares) or as otherwise contemplated by Section 7 below, the Company may not, without obtaining stockholder approval, (i) amend the terms of outstanding Stock Options or SARs to reduce the exercise price or base value of such Stock Options or SARs; (ii) cancel outstanding Stock Options or SARs in exchange for Stock Options or SARs with an exercise price or base value that is less than the exercise price or base value of the original Stock Options or SARs; or (iii) cancel outstanding Stock Options or SARs that have an exercise price or base value greater than the Fair Market Value of a share of Stock on the date of such cancellation in exchange for cash or other consideration.

7. EFFECTOF CERTAIN TRANSACTIONS

(a) Covered Transactions. Except as otherwise expressly provided in an Award agreement or by the Administrator, the following provisions will apply in the event of a Covered Transaction:

(1) Assumption or Substitution. If the Covered Transaction is one in which there is an acquiring or surviving entity, the Administrator may provide for (i) the assumption or continuation of some or all outstanding Awards or any portion thereof or (ii) the grant of new awards in substitution therefor by the acquiror or survivor or an affiliate of the acquiror or survivor.

(2) Cash-Out of Awards. Subject to Section 7(a)(5), the Administrator may provide for payment (a “cash-out”), with respect to some or all Awards or any portion thereof (including only the vested portion thereof), equal in the case of each applicable Award or portion thereof to the excess, if any, of (i) the Fair Market Value of a share of Stock multiplied by the number of shares of Stock subject to the Award or such portion, minus (ii) the aggregate exercise or purchase price, if any, of such Award or portion (or, in the case of a SAR, the aggregate base value above which appreciation is measured), in each case, on such payment and other terms and subject to such conditions (which need not be the same as the terms and conditions applicable to holders of Stock generally ) as the

-5-

Administrator determines, including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate. For the avoidance of doubt, if the per share exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the Fair Market Value of one share of Stock, such Award or portion may be cancelled with no payment due hereunder or otherwise in respect thereof.

(3) Acceleration of Certain Awards. Subject to Section 7(a)(5), the Administrator may provide that any Award requiring exercise will become exercisable, in full or in part, and/or that the issuance of any shares of Stock remaining issuable under any outstanding Award of Stock Units (including Restricted Stock Units and Performance Awards to the extent consisting of Stock Units) will be accelerated, in full or in part, in each case, on a basis that gives the holder of the Award a reasonable opportunity, as determined by the Administrator, following the exercise of the Award or the issuance of the shares, as the case may be, to participate as a stockholder in the Covered Transaction.

(4) Termination of Awards upon Consummation of Covered Transaction. Except as the Administrator may otherwise determine, each Award will automatically terminate (and in the case of outstanding shares of Restricted Stock, will automatically be forfeited) immediately upon the consummation of the Covered Transaction, other than (i) any Award that is assumed, continued or substituted for pursuant to Section 7(a)(1) and (ii) any Award that by its terms, or as a result of action taken by the Administrator, continues following the Covered Transaction.

(5) Additional Limitations. Any share of Stock and any cash or other property delivered pursuant to Section 7(a)(2) or Section 7(a)(3) with respect to an Award may, in the discretion of the Administrator, contain such limitations or restrictions, if any, as the Administrator deems appropriate, including to reflect any performance or other vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered Transaction. For purposes of the immediately preceding sentence, a cash-out under Section 7(a)(2) or an acceleration under Section 7(a)(3) will not, in and of itself, be treated as the lapsing (or satisfaction) of a performance or other vesting condition. In the case of Restricted Stock that does not vest and is not forfeited in connection with the Covered Transaction, the Administrator may require that any amounts delivered, exchanged or otherwise paid in respect of such Stock in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan.

(6) Uniform Treatment. For the avoidance of doubt, the Administrator need not treat Participants or Awards (or portions thereof) in a uniform matter, and may treat different Participants and/or Awards differently, in connection with a Covered Transaction.

(b) Changes in and Distributions with Respect to Stock.

(1) Basic Adjustment Provisions. In the event of a stock dividend, stock split or combination of shares (including a reverse stock split), recapitalization or other change in the Company’s capital structure that constitutes an equity restructuring within the meaning of the Accounting Rules, the Administrator will make appropriate adjustments to the maximum number of shares of Stock specified in Section 4(a) that may be issued under the Plan, the number and kind of shares of stock or securities underlying Awards then outstanding or subsequently granted, any exercise or purchase prices (or base values) relating to Awards and any other provision of Awards affected by such change.

(2) Certain Other Adjustments. The Administrator may also make adjustments of the type described in Section 7(b)(1) to take into account distributions to stockholders other than those provided for in Section 7(a) and 7(b)(1), or any other event, if the Administrator determines that adjustments are appropriate to avoid distortion in the operation of the Plan or any Award.

(3) Continuing Application of Plan Terms. References in the Plan to shares of Stock will be construed to include any stock or securities resulting from an adjustment pursuant to this Section 7.

-6-

8. LEGAL CONDITIONSONTHE ISSUANCEOF STOCK

The Company will not be obligated to issue any shares of Stock pursuant to the Plan or to remove any restriction from shares of Stock previously issued under the Plan until: (i) the Company is satisfied that all legal matters in connection with the issuance of such shares have been addressed and resolved; (ii) if the outstanding Stock is at the time of issuance listed on any stock exchange or national market system, the shares to be issued have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and (iii) all conditions of the Award have been satisfied or waived. The Company may require, as a condition to the exercise of an Award or the issuance of shares of Stock under an Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of the Securities Act of 1933, as amended, or any applicable state or non-U.S. securities law. Any Stock issued under the Plan will be evidenced in such manner as the Administrator determines appropriate, including book-entry registration or delivery of stock certificates. In the event that the Administrator determines that stock certificates will be issued in connection with Stock issued under the Plan, the Administrator may require that such certificates bear an appropriate legend reflecting any restriction on transfer applicable to such Stock, and the Company may hold the certificates pending the lapse of the applicable restrictions.

9. AMENDMENTAND TERMINATION

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by applicable law, and may at any time terminate the Plan as to any future grants of Awards; provided that, except as otherwise expressly provided in the Plan or the applicable Award, the Administrator may not, without the Participant’s consent, alter the terms of an Award so as to materially and adversely affect the Participant’s rights under the Award, unless the Administrator expressly reserved the right to do in the Plan or at the time the applicable Award was granted. Any amendments to the Plan will be conditioned upon stockholder approval only to the extent, if any, such approval is required by applicable law (including the Code) or stock exchange requirements, as determined by the Administrator. For the avoidance of doubt, no adjustment to any Award pursuant to the terms of Section 7 will be treated as an amendment to such Award requiring a Participant’s consent.

10. OTHER COMPENSATION ARRANGEMENTS

The existence of the Plan or the grant of any Award will not affect the right of the Company or any of its subsidiaries to grant any person bonuses or other compensation in addition to Awards under the Plan.

11. MISCELLANEOUS

(a) Waiver of Jury Trial. By accepting or being deemed to have accepted an Award under the Plan, each Participant waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan or any Award, or under any amendment, waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any such action, proceedings or counterclaim will be tried before a court and not before a jury. By accepting or being deemed to have accepted an Award under the Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or otherwise, that the Company would not, in the event of any action, proceeding, or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan, nothing herein is to be construed as limiting the ability of the Company and a Participant to agree to submit any dispute arising under the terms of the Plan or any Award to binding arbitration or as limiting the ability of the Company to require any individual to agree to submit such disputes to binding arbitration as a condition of receiving an Award hereunder.

(b) Limitation of Liability. Notwithstanding anything to the contrary in the Plan or any Award, neither the Company, nor any of its subsidiaries, nor the Administrator, nor any person acting on behalf of the Company, any of its subsidiaries, or the Administrator, will be liable to any Participant, to any permitted transferee, to the estate or beneficiary of any Participant or any permitted transferee, or to any other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by reason of the failure of an Award to satisfy the requirements of Section 422 or Section 409A or by reason of Section 4999 of the Code, or otherwise asserted with respect to any Award.

-7-

(c) Unfunded Plan. The Company’s obligations under the Plan are unfunded, and no Participant will have any right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect to any amounts due or payable under the Plan.

(d) Section 162(m). Awards granted pursuant to the Plan are intended to be eligible for exemption from the limitations of Section 162(m) of the Code by reason of the post-initial public offering transition relief set forth in Section 1.162-27(f) of the Treasury Regulations.

12. ESTABLISHMENTOF SUB-PLANS

The Administrator may at any time and from time to time establish one or more sub-plans under the Plan (for local law compliance purposes or other purposes or administrative reasons determined by the Administrator) by adopting supplements to the Plan containing, in each case, (i) such limitations on the Administrator’s discretion under the Plan and (ii) such additional terms and conditions, as the Administrator deems necessary or desirable. Each supplement so established will be deemed to be part of the Plan but will apply only to Participants within the group to which the supplement applies (as determined by the Administrator).

13. GOVERNING LAW

(a) Certain Requirements of Corporate Law. Awards and shares of Stock will be granted, issued and administered consistent with the requirements of applicable Massachusetts law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems on which the Stock is listed or entered for trading, in each case, as determined by the Administrator.

(b) Other Matters. Except as otherwise provided by the express terms of an Award agreement or under a sub-plan described in Section 12, the domestic substantive laws of the Commonwealth of Massachusetts govern the provisions of the Plan and of Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Award under the Plan or relating to the subject matter hereof or thereof, without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction.

(c) Jurisdiction. By accepting (or being deemed to have accepted) an Award, each Participant agrees or will be deemed to have agreed to (i) submit irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the geographic boundaries of the United States District Court for the District of Massachusetts for the purpose of any suit, action or other proceeding arising out of or based upon the Plan or any Award; (ii) not commence any suit, action or other proceeding arising out of or based upon the Plan or any Award, except in the federal and state courts located within the geographic boundaries of the United States District Court for the District of Massachusetts; and (iii) waive, and not assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any claim that he or she is not subject personally to the jurisdiction of the above-named courts that his or her property is exempt or immune from attachment or execution, 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 the Plan or any Award or the subject matter thereof may not be enforced in or by such court.
