(i) to select the individuals to whom Awards may from time to time be granted;

 

2

(ii) to determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock Awards, Restricted Stock Units, Unrestricted Stock Awards, Dividend Equivalent Rights and Cash Awards, or any combination of the foregoing, granted to any one or more grantees;

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees.

(c) Delegation of Authority to Grant Awards. The Administrator, in its discretion, may delegate to one or more executive officers of the Company all or part of the Administrator’s authority and duties with respect to the granting of Awards at Fair Market Value, to individuals who are not Reporting Persons. Any such delegation by the Administrator shall include a limitation as to the amount or value of Awards that may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price of any Stock Option, the conversion ratio or price of other Awards and the vesting criteria. The Administrator may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator’s delegate or delegates that were consistent with the terms of the Plan.

(d) Indemnification. Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss,

 

3

damage or expense (including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors’ and officers’ liability insurance coverage which may be in effect from time to time.

Section 4. Stock Issuable Under the Plan; Changes in Stock; Substitution; Director Limits

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 31,750,000 shares (the “Initial Limit”), plus on January 1, 2023 and on January 1 of each year thereafter, the number of shares reserved and available for issuance under the Plan shall be increased by four percent (4%) of the number of shares of Stock issued and outstanding on the immediately preceding December 31, or such lesser number of shares as approved by the Administrator (the “Annual Increase”), subject to adjustment as provided in Section 4(b) (the “Pool”). Subject to such overall limitation, the maximum aggregate number of shares of Stock that may be issued in the form of Incentive Stock Options shall not exceed the Initial Limit cumulatively increased on January 1, 2023 and on January 1 of each year thereafter by the lesser of the Annual Increase for each year or a number of shares of Stock equal to twice the Initial Limit, subject to adjustment as provided in Section 4(b). For purposes of this limitation, in respect of any shares of Stock under any Award under the Plan which shares are forfeited, canceled, held back upon the exercise of an Option or settlement of an Award to satisfy the exercise price or tax withholding, satisfied without the issuance of Stock, otherwise terminated, or, for shares of Stock issued pursuant to any unvested full value Award, reacquired by the Company at not more than the grantee’s purchase price (“Unissued Shares”), the number of shares of Stock that were removed from the Pool for such Unissued Shares shall be added back to the Pool and, to the extent consistent with the requirements of Section 422 of the Code such shares may be issued as Incentive Stock Options. The shares available for issuance from the Pool may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company and held in its treasury, or shares purchased on the open market. In addition, Substitute Awards shall not reduce the Stock authorized for grant under the Plan, including the shares available to be issued in the form of Incentive Stock Options to the extent consistent with the requirements of Section 422 of the Code; nor shall Stock subject to a Substitute Award again be available for Awards under the Plan to the extent of any forfeiture, cancelation, reacquisitions, expiration, termination, cash settlement or non-issuance, as set forth above.

(b) Changes in Stock. Subject to Section 19 hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for a different number or kind of securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, (ii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price per share subject to each outstanding Restricted Stock Award, and (iv) the price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options or Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The adjustment by the Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares.

The Administrator may also adjust the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration material changes in accounting practices or principles, extraordinary dividends, acquisitions or dispositions of stock or property or any other event if it is determined by the Administrator that such adjustment is appropriate to avoid distortion in the operation of the

 

4

Plan, provided that no such adjustment shall be made in the case of an Incentive Stock Option, without the consent of the grantee, if it would constitute a modification, extension or renewal of the Option within the meaning of Section 424(h) of the Code.

(c) Substitute Awards. The Administrator may grant Awards (“Substitute Awards”) under the Plan in substitution for stock and stock-based awards held by employees, directors or other key persons of another corporation in connection with the merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the Substitute Awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances. For the avoidance of doubt, the term “Substitute Awards” does not include awards that were previously issued under the GreenLight Biosciences, Inc. 2012 Stock Incentive Plan, and subsequently assumed in connection with the transactions contemplated by the Business Combination Agreement.

(d) Maximum Awards to Independent Directors. Notwithstanding anything to the contrary in this Plan, the value of all Awards awarded under this Plan and all other cash compensation paid by the Company to any Independent Director in any calendar year shall not exceed: (i) $500,000 in the first calendar year an individual becomes an Independent Director and (ii) $375,000 in any other calendar year; provided, however, that this limitation shall be determined without regard to amounts paid to an Independent Director (including retirement benefits and severance payments) in respect of any services provided in any capacity (including employee or consultant) other than as an Independent Director; and provided further, that the Board may make exceptions to this limit for a non-executive chair of the Board with the approval of a majority of the disinterested directors.

Section 5. Eligibility

Incentive Stock Options may only be granted to employees (including officers and directors who are also employees) of the Company or a Subsidiary. All other Awards may be granted to employees, officers, directors and key persons (including consultants and prospective employees) of the Company and its Subsidiaries.

Section 6. Stock Options

(a) Stock Options. Any Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve, and may be either Incentive Stock Options or Nonstatutory Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that an Option does not qualify as an Incentive Stock Option, it shall be deemed a Nonstatutory Stock Option.

(b) Stock Options granted pursuant to this Section 6 shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the optionee’s election, subject to such terms and conditions as the Administrator may establish.

(i) Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 6 shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the Grant Date. If an employee owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the option price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the Grant Date.

(ii) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than 10 years after the date the Stock Option is granted. If an employee owns or

 

5

is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the term of such Stock Option shall be no more than five years from the date of grant. Notwithstanding the foregoing, in the event that on the last business day of the term of an Option (other than an Incentive Stock Option) (i) the exercise of the Option is prohibited by applicable law or (ii) Stock may not be purchased or sold by certain employees or directors of the Company due to a black-out period of a Company policy or a lock-up agreement undertaken in connection with an offering of securities of the Company, the term of the Option shall be extended for a period of thirty (30) days following the end of the legal prohibition, black-out period or lock-up agreement subject to the requirements of Section 409A; provided, however, that no such extension will be made if the exercise price of such Option at the date the initial term would otherwise expire is above the Fair Market Value of the Stock on such date.

(iii) Exercisability; Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the Grant Date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options.

(iv) Method of Exercise. Stock Options may be exercised in whole or in part, by giving written notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods to the extent provided in the Option Award agreement:

(A) In cash, or by certified or bank check or other instrument acceptable to the Administrator;

(B) Through the delivery (or attestation to the ownership) of shares of Stock that are not then subject to restrictions under any company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

(C) By a “cashless exercise” arrangement pursuant to which the optionee delivers to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure;

(D) By a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; or

(E) Any other method permitted by the Administrator.

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company of the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Option Award agreement or applicable provisions of laws. In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of shares attested to.

(c) Annual Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of

 

6

the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a Nonstatutory Stock Option.

(d) Non-transferability of Incentive Stock Options. No Incentive Stock Option shall be transferable by the optionee otherwise than by will or by the laws of descent and distribution and Incentive Stock Options shall be exercisable, during the optionee’s lifetime, only by the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity.

Section 7. Stock Appreciation Rights

(a) Nature of Stock Appreciation Rights. A Stock Appreciation Right is an Award entitling the recipient to receive cash or shares of Stock, as determined by the Administrator, having a value equal to the excess of the Fair Market Value of a share of Stock on the date of exercise over the grant price of the Stock Appreciation Right multiplied by the number of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised. Stock Appreciation Rights shall be subject to the following terms and conditions and shall contain such other terms and conditions as shall be determined from time to time by the Administrator.

(i) Grant Price of Stock Appreciation Rights. The grant price of a Stock Appreciation Right shall not be less than 100 percent of the Fair Market Value of the Stock on the Grant Date.

(ii) Grant of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator in tandem with, or independently of, any Stock Option granted pursuant to Section 6 of the Plan.

(iii) Stock Appreciation Right Term. The term of a Stock Appreciation Right may not exceed ten years. Notwithstanding the foregoing, in the event that on the last business day of the term of a Stock Appreciation Right (i) the exercise of the Stock Appreciation Right is prohibited by applicable law or (ii) Stock may not be purchased or sold by certain employees or directors of the Company due to a black-out period of a Company policy or a lock-up agreement undertaken in connection with an offering of securities of the Company, the term of the Stock Appreciation Right shall be extended for a period of thirty (30) days following the end of the legal prohibition, black-out period or lock-up agreement subject to the requirements of Section 409A; provided, however, that no such extension will be made if the grant price of such Stock Appreciation Right at the date the initial term would otherwise expire is above the Fair Market Value of the Stock on such date. The terms and conditions of each such Award shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

Section 8. Restricted Stock Awards

(a) Nature of Restricted Stock Awards. A Restricted Stock Award is an Award entitling the recipient to acquire, at such purchase price (if any) as determined by the Administrator, shares of Stock subject to such restrictions and conditions as the Administrator may determine at the time of grant (“Restricted Stock”). Conditions may be based on a continuing Service Relationship and/or achievement of pre-established performance goals and objectives. The grant of a Restricted Stock Award is contingent on the grantee executing a Restricted Stock Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

(b) Rights as a Stockholder. Upon execution of a written instrument setting forth the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Stock, subject to any exceptions or conditions contained in the written instrument evidencing the Restricted Stock Award. Unless the Administrator shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession of the Company until such Restricted Stock is vested as provided in Section 8(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank.

 

7

(c) Restrictions. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award agreement. If a grantee’s Service Relationship terminates for any reason, the Company shall have the right to repurchase Restricted Stock that has not vested as of the Termination Date at its original purchase price, if any, from the grantee or the grantee’s legal representative. Unless otherwise stated in the written instrument evidencing the Restricted Stock Award, any Restricted Stock for which the grantee did not pay any purchase price and which is not vested as of the grantee’s Termination Date shall automatically be forfeited immediately following such termination.

(d) Vesting of Restricted Stock. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock and the Company’s right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Shares and shall be deemed “vested.” Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 17 below, in writing after the Award agreement is issued, a grantee’s rights in any shares of Restricted Stock that have not vested shall automatically terminate upon the grantee’s Termination Date and such shares shall be subject to forfeiture or the Company’s right of repurchase as provided in Section 8(c) above.

Section 9. Restricted Stock Units

(a) Nature of Restricted Stock Units. A Restricted Stock Unit is a bookkeeping entry representing the right to receive, upon its vesting, one share of Stock (or a percentage or multiple of one share of Stock if so specified in the Award Agreement evidencing the Award) for each Restricted Stock Unit awarded to a grantee and represents an unfunded and unsecured obligation of the Company. The Administrator shall determine the restrictions and conditions applicable to each Restricted Stock Unit at the time of grant. Conditions may be based on a continuing Service Relationship and/or achievement of pre-established performance goals and objectives. The terms and conditions of each such Award Agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. At the end of the vesting period, the Restricted Stock Units, to the extent vested, shall be settled in the form of shares of Stock. Notwithstanding the foregoing, the Administrator, in its discretion, may determine either at the time of grant or at the time of settlement, that a Restricted Stock Unit shall be settled in cash. To the extent that an award of Restricted Stock Units is subject to Section 409A, it may contain such additional terms and conditions as the Administrator shall determine in its sole discretion in order for such Award to comply with the requirements of Section 409A.

(b) Rights as a Stockholder. A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon settlement of Restricted Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the unissued shares of Stock underlying his Restricted Stock Units, subject to such terms and conditions as the Administrator may determine.

(c) Termination. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 18 below, in writing after the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate immediately upon termination of the grantee’s Service Relationship for any reason.

Section 10. Unrestricted Stock Awards

Grant or Sale of Unrestricted Stock. The Administrator may, in its sole discretion, grant (or sell at a purchase price (determined by the Administrator) an Unrestricted Stock Award to any grantee, pursuant to which such grantee may receive shares of Stock free of any restrictions (“Unrestricted Stock”) under the Plan. Unrestricted Stock Awards may be granted or sold as described in the preceding sentence in respect of past services or other valid consideration, or in lieu of any cash compensation due to such participant.

 

8

Section 11. Cash Awards

The Administrator, in its discretion, may provide for cash payments to be made under the Plan as a form of Award. The Administrator shall determine a cash payment amount, formula or payment range for the Cash Award, the conditions upon which the Cash Award shall become vested or payable, and such other terms and conditions as the Administrator shall determine. Payment, if any, with respect to a Cash Award shall be made in accordance with the terms of the Award.

Section 12. Dividend Equivalent Rights

(a) Dividend Equivalent Rights. A Dividend Equivalent Right is an Award entitling the recipient to receive credits based on cash dividends that would be paid on the shares of Stock specified in the Dividend Equivalent Right (or other Award to which it relates) if such shares were held by the recipient. A Dividend Equivalent Right may be granted hereunder to any participant, as a component of another Award (other than an Option or Stock Appreciation Right) or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the grant. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of another Award may provide that such Dividend Equivalent Right shall be settled upon exercise, settlement, or payment of, or lapse of restrictions on, such other award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as such other award. A Dividend Equivalent Right granted as a component of another Award may also contain terms and conditions different from such other award.

Section 13. Tax Withholding

(a) Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes taxable, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any Federal, state, local or foreign taxes of any kind required by law to be withheld with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company’s obligation to deliver stock certificates to any grantee is subject to and is conditioned on tax obligations being satisfied by the grantee.

(b) Payment in Stock. If provided in the instrument evidencing an Award, either the grantee or the Company may elect to have the statutory minimum required tax withholding obligation satisfied, in whole or in part, by (i) withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy such withholding amount due, or (ii) allowing a grantee to transfer to the Company shares of Stock owned by the grantee with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy such withholding amount due.

Section 14. Transferability of Awards

No Award shall be transferable by the grantee otherwise than by will or by the laws of descent and distribution and all Awards shall be exercisable, during the grantee’s lifetime, only by the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. Notwithstanding the foregoing, the Administrator, in its sole discretion, may provide in the Award Agreement regarding a given Award (other than an Incentive Stock Option), or may agree in writing with respect to an outstanding Award, that the grantee may transfer the Award to members of the grantee’s immediate family, to trusts for the benefit of such family

 

9

members, or to partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award.

Section 15. Section 409A Awards

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A, and the Plan and all Award Agreements shall be interpreted accordingly. To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any 409A Award may not be accelerated or postponed except to the extent permitted by Section 409A. Notwithstanding the foregoing, neither the Company nor any Subsidiary shall have any liability or obligation to any Award recipient or any other person for any taxes, interests or penalties that may arise as a result of any failure of the Plan or an Award to comply with, or be exempt from, Section 409A.

Section 16. Termination of Service Relationship

For purposes of the Plan, unless as otherwise set forth in an Award Agreement, the following events shall not be deemed a termination of a Service Relationship:

(a) a transfer to the employment or service of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another;

(b) any change in status between full-time and part-time employment, or a change in relationship between employee and consultant; or

(c) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing.

Section 17. Amendments and Termination

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder’s consent. To the extent required under the rules of any securities exchange or market system on which the Stock is listed, or to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code, Plan amendments shall be subject to approval by the Company stockholders. Nothing in this Section 17 shall limit the Administrator’s authority to take any action permitted pursuant to Sections 3(b) or 4(c).

Section 18. Status of Plan

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general

 

10

creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence.

Section 19. Change in Control Provisions

(a) In the event of and subject to the consummation of a Change in Control Transaction as defined in this Section 19, the parties thereto may cause the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. To the extent the parties to such Change in Control Transaction do not provide for the assumption, continuation or substitution of Awards, upon the closing of the Change in Control Transaction (the “Closing”) the Plan and all outstanding Awards granted hereunder shall terminate. In such case, except as may be otherwise provided in the relevant Award Agreement, all Options and Stock Appreciation Rights with time-based vesting conditions or restrictions that are not vested and/or exercisable immediately prior to the effective time of the Change in Control Transaction shall become fully vested and exercisable as of the Closing, all other Awards with time-based vesting, conditions or restrictions shall become fully vested and nonforfeitable as of the Closing, and all Awards with conditions and restrictions relating to the attainment of performance goals may become vested and nonforfeitable in connection with a Change In Control Transaction in the Administrator’s discretion or to the extent specified in the relevant Award Agreement. In the event of such termination, (i) the Company shall have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the “Transaction Price” (as defined below) multiplied by the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Transaction Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation Rights (provided that, in the case of an Option or Stock Appreciation Right with an exercise price equal to or greater than the Transaction Price, such Option or Stock Appreciation Right shall be cancelled for no consideration); or (ii) each grantee shall be permitted, within a specified period of time prior to the consummation of the Change in Control Transaction as determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. The Company shall also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards in an amount equal to the Transaction Price multiplied by the number of vested shares of Stock under such Awards.

(b) “Change in Control Transaction” shall mean (i) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity, (ii) a merger, reorganization or consolidation pursuant to which the holders of the Company’s outstanding voting power and outstanding stock immediately prior to such transaction do not own a majority of the outstanding voting power and outstanding stock or other equity interests of the resulting or successor entity (or its ultimate parent, if applicable) immediately upon completion of such transaction, (iii) the sale of all of the Stock of the Company to an unrelated person, entity or group thereof acting in concert, or (iv) any other transaction in which the owners of the Company’s outstanding voting power immediately prior to such transaction do not own at least a majority of the outstanding voting power of the Company or any successor entity immediately upon completion of the transaction other than as a result of the acquisition of securities directly from the Company.

(c) “Transaction Price,” with respect to a Change in Control Transaction, shall mean the consideration payable, or otherwise to be received by stockholders of the Company, per share of Stock, as determined by the Administrator.

 

11

Section 20. General Provisions

(a) No Distribution; Compliance with Legal Requirements. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof. No shares of Stock shall be issued pursuant to an Award until all applicable securities law and other legal and stock exchange or similar requirements, whether located in the United States or a foreign jurisdiction, have been satisfied. The Administrator may require the placing of such stop-orders and restrictive legends on certificates, or notations on book records, for Stock and Awards as it deems appropriate. In addition to the terms and conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements, and representations as the Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator.

(b) Issuance of Stock. To the extent certificated, stock certificates shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records).

(c) Awards to Non U.S. Recipients. Notwithstanding anything to the contrary contained in this Plan, Awards may be made to an individual who is a foreign national or employed or performing services outside of the United States on such terms and conditions different from those specified in the Plan as the Administrator considers necessary or advisable to achieve the purposes of the Plan or to comply with applicable laws. The Administrator may establish subplans with respect to such Awards and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or advisable (and such subplans and/or modifications shall be incorporated into and made part of this Plan). Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law.

(d) Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary.

(e) Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to such company’s insider trading policy, as in effect from time to time.

(f) Forfeiture of Awards under Sarbanes-Oxley Act; Clawback Policy. If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under the securities laws, then, to the extent required by law, any grantee who is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002 shall reimburse the Company for the amount of any Award received by such individual under the Plan during the 12-month period following the first public issuance or filing with the United States Securities and Exchange Commission, as the case may be, of the financial document embodying such financial reporting requirement. In addition, Awards under the Plan shall be subject to any policy of the Company providing for forfeiture of incentive or performance based compensation in the event of an individual’s misconduct, or certain

 

12

changes in the financial reporting or financial results of the Company (such policy, a “Clawback Policy”), as may be in effect from time to time.

(g) Delivery and Execution of Electronic Documents. To the extent permitted by applicable law, the Company may (i) deliver by email or other electronic means (including posting on a web site maintained by the Company or by a third party under contract with the Company) all documents relating to the Plan and any Award thereunder (including without limitation, prospectuses required by the SEC) and all other documents that the Company is required to deliver to its security holders (including without limitation, annual reports and proxy statements) and (ii) permit participants in the Plan to electronically execute applicable Plan documents (including but not limited to, Award Agreements) in a manner prescribed by the Administrator. 

Section 21. Effective Date of Plan, Term of Plan

This Plan shall become effective upon the date immediately preceding the date of the closing of the transactions contemplated by the Business Combination Agreement, subject to prior stockholder approval in accordance with applicable state law, the Company’s bylaws and articles of incorporation, and applicable stock exchange rules. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan is approved by the Board.

Section 22. Governing Law

This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware, applied without regard to conflict of law principles.

1. Purpose of the Plan

The purpose of the GreenLight Biosciences Holdings, PBC 2022 Employee Stock Purchase Plan (the “Plan”) is to provide eligible employees of GreenLight Biosciences Holdings, PBC (the “Company”) and each Designated Company (as defined below) with the opportunity to purchase shares of the Company’s common stock, par value $0.0001 per share (the “Stock”).

The Plan is comprised of two components: (a) the “423 Component,” pursuant to which rights to purchase Stock that satisfy the requirements for an “employee stock purchase plan” within the meaning of Section 423(b) of the Code (a “Qualified ESPP”) may be granted to eligible Employees, and (b) the “Non-423 Component,” pursuant to which rights to purchase Stock under the Plan that are not intended to satisfy such requirements may be granted to eligible employees. The Company intends (but makes no undertaking or representation to maintain) the 423 Component to qualify as a Qualified ESPP. The provisions of the 423 Component, accordingly, will be construed in a manner that is consistent with the requirements of Section 423 of the Code. Except as otherwise provided in the Plan or determined by the Administrator, the Non-423 Component will operate and be administered in the same manner as the 423 Component. In addition, the Company may make separate Offerings under the 423 Component which vary in terms (provided that such terms are not inconsistent with the provisions of the Plan, the Offering Document or the requirements of a Qualified ESPP), and the Company will designate which Designated Company is participating in each separate Offering.

4. Shares Authorized

Subject to the adjustment provisions of Section 15, the maximum number of shares of Stock that may be issued under the Plan will be 2,000,000 shares, plus an additional number of shares added on January 1, 2023 and January 1 of each year thereafter until the Plan terminates pursuant to Section 17, in an amount equal to the lesser of (i) 4,000,000 shares of Stock, (ii) four percent (4%) of the number of shares of Stock issued and outstanding on the immediately preceding December 31, or (iii) such lesser number of shares of Stock as determined by the Administrator. If any Option granted under the Plan terminates without having been exercised in full, the shares of Stock not purchased under such Option will again become available for issuance under the Plan. Shares issued upon exercise of an Option may be from authorized but unissued Stock, from shares held in the treasury of the Company, or from any other proper source.

5. Eligibility

Except as otherwise determined by the Administrator in advance of an Offering, all Employees of the Company and each Designated Company are eligible to participate in any one or more of the Offerings under the Plan. Notwithstanding any other provision herein, individuals who are not contemporaneously classified as employees of the Company or a Designated Company for purposes of the Company’s or applicable Designated Company’s payroll system are not considered to be Employees of the Company or any Designated Company and shall not be eligible to participate in the Plan.

6. Offerings

The Company may make one or more offerings to eligible Employees to purchase Stock under the Plan (“Offerings”). Unless otherwise determined by the Administrator, an Offering will begin on the first Trading Day occurring on or after each January 1 and July 1, and will end on the last Trading Date occurring before the July 1 and January 1 thereafter, respectively. The Administrator may, in its discretion, designate a different period for any Offering, provided that no Offering shall exceed 27 months in duration.

7. Participation

An eligible Employee may participate in an Offering by submitting an enrollment form to the Company or an agent designated by the Company at least 15 business days before the Offering Commencement Date (or by such other deadline as shall be established by the Administrator for the Offering). The enrollment form (which may be in an electronic format or such other method as determined by the Company in accordance with the Company’s practices) will (a) state a whole percentage or amount to be deducted from the Employee’s Compensation per pay period, (b) authorize the purchase of Stock in each Offering in accordance with the terms of the Plan and (c) specify the exact name or names in which shares of Stock purchased for such individual are to be issued. An Employee who does not enroll in accordance with these procedures will be deemed to have waived the right to participate. Unless a Participant files a new enrollment form or withdraws from the Plan, such Participant’s deductions or contributions and purchases will continue at the same percentage or amount of Compensation for future Offerings, provided he or she remains eligible.

8. Employee Contributions.

An eligible Employee may authorize payroll deductions or contributions at a minimum of one percent (1%) up to a maximum of 15 percent (15%) of such Employee’s Compensation for each pay period or such other

 

3

maximum as may be specified by the Administrator in advance of an Offering. The Company will maintain book accounts showing the amount of payroll deductions or contributions made by each Participant for each Offering. No interest will accrue or be paid on payroll deductions or contributions, except as may be required by applicable law. If payroll deductions or contributions for purposes of the Plan are prohibited or otherwise problematic under applicable law (as determined by the Administrator in its discretion), the Administrator may require Participants to contribute to the Plan by such other means as determined by the Administrator. Any reference to “payroll deductions or contributions” in this Section 8 (or in any other section of the Plan) will similarly cover contributions by other means made pursuant to this Section 8.

9. Contribution Changes; Withdrawal

(a) Except as may be determined by the Administrator in advance of an Offering, a Participant may not increase or decrease his or her payroll deduction or contributions during any Offering, but may increase or decrease his or her payroll deduction or contributions with respect to the next Offering by filing a new enrollment form at least fifteen (15) business days before the next Offering Commencement Date (or by such other deadline as shall be established by the Administrator for the Offering). The Administrator may, in advance of any Offering, establish rules permitting a Participant to increase, decrease or terminate his or her payroll deduction or contributions during an Offering.

(b) A Participant may withdraw from participation in the Plan by delivering a written notice of withdrawal to the Company or an agent designated by the Company (in accordance with such procedures as may be established by the Administrator). The Participant’s withdrawal will be effective as of the next business day. Following a Participant’s withdrawal, the Company will promptly refund such individual’s entire account balance under the Plan to him or her (after payment for any Stock purchased before the effective date of withdrawal). Partial withdrawals are not permitted. Such an Employee may not begin participation again during the remainder of the Offering, but may enroll in a subsequent Offering in accordance with Section 7.

10. Grant of Options

On each Offering Commencement Date, the Company will grant to each eligible Employee who is then a Participant in the Plan an option (“Option”) to purchase, on the last day of such Offering (the “Exercise Date”) and at the Option Price (as defined herein) hereinafter provided for, the lowest of (a) a number of shares of Stock determined by dividing such Participant’s accumulated payroll deductions or contributions on such Exercise Date by the Option Price, (b) the number of shares of Stock determined by dividing $25,000 by the Fair Market Value of the Stock on the Offering Commencement Date for such Offering; or (c) such other lesser maximum number of shares as shall have been established by the Administrator in advance of the Offering; provided, however, that such Option shall be subject to the limitations set forth below. Each Participant’s Option shall be exercisable only to the extent of such Participant’s accumulated payroll deductions or contributions on the Exercise Date. The purchase price for each share purchased under each Option (the “Option Price”) will be eighty-five percent (85%) of the Fair Market Value of the Stock on the Offering Commencement Date or the Exercise Date, whichever is less.

Notwithstanding the foregoing, no Employee shall be eligible for the grant of an Option under the 423 Component if such Employee, immediately after the Option was granted, would be treated as owning stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or any Parent or Subsidiary. For purposes of the preceding sentence, the attribution rules of Section 424(d) of the Code shall apply in determining the stock ownership of a Participant. In addition, no Employee may be granted an Option under the 423 Component which permits his or her rights to purchase stock under the Plan, and any other employee stock purchase plan of the Company and its Parents and Subsidiaries, to accrue at a rate which exceeds $25,000 of the Fair Market Value of the Stock (determined on the option grant date or dates) for each calendar year in which the Option is outstanding at any time.

 

4

11. Exercise of Option and Purchase of Shares

Each Employee who continues to be a Participant in the Plan on an Exercise Date shall be deemed to have exercised his or her Option on such date and shall acquire from the Company such number of whole shares of Stock reserved for the purpose of the Plan as his or her accumulated payroll deductions or contributions on such date will purchase at the Option Price, subject to any other limitations contained in the Plan. Unless otherwise determined by the Administrator in advance of an Offering, any amount remaining in a Participant’s account at the end of an Offering solely by reason of the inability to purchase a fractional share will be carried forward to the next Offering and any other balance remaining in a Participant’s account at the end of an Offering will be refunded to the Participant promptly.

Notwithstanding the foregoing, if the total number of shares of Stock that would otherwise be purchased on any Exercise Date plus the number of shares purchased under previous Offerings under the Plan exceeds the maximum number of shares issuable under the Plan, the shares then available shall be apportioned among Participants in proportion to the amount of payroll deductions or contributions accumulated on behalf of each Participant that would otherwise be used to purchase Stock on such Exercise Date.

12. Issuance of Certificates

Certificates or book-entries at the Company’s transfer agent representing shares of Stock purchased under the Plan may be issued only in the name of the Employee, in the name of the Employee and another person of legal age as joint tenants with rights of survivorship, or in the name of a broker authorized by the Employee to be his, her or their, nominee for such purpose.

13. Rights on Termination or Transfer of Employment

If a Participant’s employment terminates for any reason before the Exercise Date for any Offering, no payroll deduction or contributions will be taken from any pay due and owing to the Participant and the balance in the Participant’s account will be paid to such Participant or, in the case of such Participant’s death, if permitted by the Administrator and valid under applicable law, to his or her designated beneficiary or to the legal representative of his or her estate. An Employee will be deemed to have terminated employment, for this purpose, if the corporation that employs him or her, having been a Designated Company, ceases to be a Subsidiary or Affiliate, or if the Employee is transferred to any corporation other than the Company or a Designated Company. Unless otherwise determined by the Administrator, a Participant whose employment transfers between, or whose employment terminates with an immediate rehire (with no break in service) by, Designated Companies or a Designated Company and the Company will not be treated as having terminated employment for purposes of participating in the Plan or an Offering; provided, however, that if a Participant transfers from an Offering under the 423 Component to an Offering under the Non-423 Component, the exercise of the Participant’s Option will be qualified under the 423 Component only to the extent that such exercise complies with Section 423 of the Code. If a Participant transfers from an Offering under the Non-423 Component to an Offering under the 423 Component, the exercise of the Participant’s Option will remain non-qualified under the Non-423 Component. Further, an Employee will not be deemed to have terminated employment for purposes of this Section 13, if the Employee is on an approved leave of absence where the Employee’s right to reemployment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise provides in writing.

14. Special Rules and Sub-Plans

Notwithstanding anything herein to the contrary, the Administrator may adopt special rules or sub-plans applicable to the Employees of a particular Designated Company, whenever the Administrator determines that such rules are necessary or appropriate for the implementation of the Plan in a jurisdiction where such Designated Company has Employees, regarding, without limitation, eligibility to participate in the Plan, handling and making of payroll deductions or contributions by other means, establishment of bank or trust accounts to

 

5

hold payroll deductions or contributions, payment of interest, conversion of local currency, obligation to pay payroll tax, withholding procedures and handling of share issuances, any of which may vary according to applicable requirements; provided that if such special rules or sub-plans are inconsistent with the requirements of Section 423(b) of the Code the Employees subject to such special rules or sub-plans will participate in the Non-423 Component. Any special rules or sub-plans established pursuant to this Section 14 shall, to the extent possible, result in the Employees subject to such rules having substantially the same rights as other Participants in the Plan.

15. Adjustment in Case of Changes Affecting Stock; Change in Control

In the event of a subdivision of outstanding shares of Stock, the payment of a dividend in Stock or any other change affecting the Stock, the number of shares approved for the Plan and the share limitation set forth in Section 10 shall be equitably or proportionately adjusted to give proper effect to such event. In the case of and subject to the consummation of a Change in Control, the Administrator, in its discretion, and on such terms and conditions as it deems appropriate, is hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any right under the Plan or to facilitate such transactions or events:

(a) to provide for either (i) termination of any outstanding Option in exchange for an amount of cash, if any, equal to the amount that would have been obtained upon the exercise of such Option had such Option been currently exercisable or (ii) the replacement of such outstanding Option with other options or property selected by the Administrator in its sole discretion;

(b) to provide that the outstanding Options under the Plan shall be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for similar options covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices;

(c) to make adjustments in the number and type of shares of Stock (or other securities or property) subject to outstanding Options under the Plan and/or in the terms and conditions of outstanding Options and Options that may be granted in the future;

(d) to provide that the Offering with respect to which an Option relates will be shortened, and that the Exercise Date with respect to such Offering shall be the last Trading Date of such shortened period (the “New Exercise Date”). The New Exercise Date will occur before the date of the Change in Control. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the New Exercise Date and that the Participant’s Option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering; and

(e) to provide that all outstanding Options shall terminate without being exercised and all amounts in the accounts of Participants shall be promptly refunded.

16. Amendment of the Plan

The Board may at any time and from time to time amend the Plan in any respect, except that (i) without the approval within 12 months of such Board action by the stockholders, no amendment shall be made increasing the number of shares approved for the 423 Component of the Plan or making any other change to the 423 Component of the Plan that would require stockholder approval in order for the Plan, as amended, to qualify as an “employee stock purchase plan” under Section 423(b) of the Code; and (ii) no amendment to the Plan that would require stockholder approval under the rules of any securities exchange or market system will be made without such approval.

 

6

17. Termination of the Plan; Term of Plan

The Plan may be terminated at any time by the Board. Upon termination of the Plan, all amounts in the accounts of Participants shall be promptly refunded. Unless terminated earlier, the Plan shall automatically terminate on the ten-year anniversary of the Effective Date.

18. Compliance with Law

The Company’s obligation to sell and deliver Stock under the Plan is subject to applicable laws and the completion of any registration or qualification of the Stock under any U.S. or non-U.S. local, state or federal securities or exchange control law, or under rulings or regulations of the SEC or of any other governmental regulatory body, and to obtaining any approval or other clearance from any U.S. and non-U.S. local, state or federal governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. The Company is under no obligation to register or qualify the Stock with the SEC or any other U.S. or non-U.S. securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of such stock.

19. Miscellaneous

(a) No Rights as a Shareholder. Neither the granting of an Option to a Participant nor the deductions or contributions from his or her pay shall result in such Participant becoming a holder of the shares of Stock covered by an Option under the Plan until such shares have been purchased by and issued to him or her.

(b) Required Notification upon Sale of Shared under the 423 Component. Each Participant agrees, by entering the 423 Component of the Plan, to give the Company prompt notice of any disposition of shares purchased under the Plan where such disposition occurs within two years after the date of grant of the Option pursuant to which such shares were purchased or within one year after the date such shares were purchased.

(c) No Transferability. Rights under the Plan are not transferable by a Participant other than by will or the laws of descent and distribution, and are exercisable during the Participant’s lifetime only by the Participant.

(d) No Right to Employment. Neither eligibility to participate in nor participation in the Plan shall be deemed to create any right of continued employment or in any way affect to the right of the Company or a Designated Company to terminate employment of any Employee.

(e) Unfunded Plan. All funds received or held by the Company under the Plan may be combined with other corporate funds and may be used for any corporate purpose, unless otherwise required under applicable law.

(f) Governing Law. The Plan and all Options and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware, applied without regard to conflict of law principles

20. Tax Withholding

Participation in the Plan is subject to any applicable U.S. and non-U.S. federal, state or local tax withholding requirements on income the Participant realizes in connection with the Plan. Each Participant agrees, by entering the Plan, that the Company or any Subsidiary or Affiliate may withhold from a Participant’s wages, salary or other compensation at any time the amount necessary for the Company or any Subsidiary or Affiliate to meet applicable withholding obligations, including any withholding required to make available to the Company or any Subsidiary or Affiliate any tax deductions or benefits attributable to the sale or disposition of Stock by such Participant.
