 THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for other good and valuable consideration,
including the execution and delivery of that certain Amendment No. 1 dated as of the date hereof to Master Loan and Security Agreement No. FORMX (the “Loan Amendment”) dated as of March 26, 2009 by and between Forma Therapeutics,
Inc., a Delaware corporation, and ATEL VENTURES, INC., this Warrant is issued to ATEL VENTURES, INC., in its capacity as Trustee for its assignee affiliates identified in that certain Amendment and Restatement of Inter-Company Trust Agreement for

liability company (the “Company”). 
 1. ISSUANCE. 

Subject to the terms and conditions hereinafter set forth, the Holder is entitled upon surrender of this Warrant and the duly executed
subscription form annexed hereto as Appendix 1, at the office of the Company, 500 Arsenal Street, Watertown, MA 02472, or such other office as the Company shall notify the Holder of in writing, to purchase from the Company up to
                     shares of fully paid and non-assessable shares (the “Shares”) of the
Company’s Series B Preferred Shares (“Preferred Shares”), at a purchase price per Share of $1.20 (the “Exercise Price”). This Warrant may be exercised in whole or in part at any time and from time to time until 5:00 PM,
Pacific time, on the Expiration Date set forth above, and shall be void thereafter. Until such time as this Warrant is exercised in full or expires, the Exercise Price and the Shares are subject to adjustment from time to time as hereinafter
provided. 
  

 2. EXERCISE. 

(a) Method of Exercise. Holder may exercise this Warrant by delivering this Warrant together with a duly executed Notice of Exercise in
substantially the form attached as Appendix 1 hereto to the principal office of the Company. Unless Holder is exercising the conversion right set forth in Section 2(b), Holder shall also deliver to the Company a check for the aggregate
Exercise Price for the Shares being purchased. 
 (b) Conversion Right. In lieu of exercising this Warrant as specified in
Section 2(a), Holder may from time to time convert this Warrant, in whole or in part, into a number of Shares determined as follows: 
  

	
	X = Y(A-B)
	A

  

			
	 where:        
	  	X = the number of Shares to be issued to the Holder.
		  	Y = the number of Shares with respect to which this
		  	 Warrant is being exercised.

		  	A= the Fair Market Value (as determined pursuant to
		  	 Section 2 (c) below) of one Share.

		  	B = the Exercise Price.

 (c) Fair Market Value. 

(i) If Common Shares are traded on a nationally recognized securities exchange or over the counter market, the fair market value of one Share
shall be the average closing price of a Common Share over the five day trading period immediately preceding the date of Holder’s Notice of Exercise to the Company (or such lesser number of trading days as the shares have been publicly traded).
Notwithstanding the foregoing, in the event the Warrant is exercised in connection with the Company’s initial public offering of Common Shares, the fair market value per share shall be the product of (i) the per share offering price to the
public of the Company’s initial public offering, and (ii) the number of Common Shares into which each Preferred Share is convertible at the time of exercise. 

(ii) If Common Shares are not traded on a nationally recognized securities exchange or over the counter market, the board of managers of the
Company (the “Board of Directors”) shall determine the fair market value of a Common Share in its reasonable good faith judgment. The foregoing notwithstanding, if Holder advises the Board of Directors in writing that Holder disagrees with
such determination, then the Company and Holder shall promptly agree upon a reputable investment banking firm to undertake such valuation. If the valuation of such investment banking firm is greater than that determined by the Board of Directors by
five percent (5%) or more, then all fees and expenses of such investment banking firm shall be paid by the Company. In all other circumstances, such fees and expenses shall be paid by Holder. The determination of any such investment banking firm
shall be conclusive in any event. 

  
 - 2 - 

 (d) Delivery of Certificate and New Warrant. Promptly after Holder exercises or
converts this Warrant, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the right to purchase the Shares not so
acquired. 
 (e) Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of
this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 
 (f)
Assumption on Sale, Merger, or Consolidation of the Company. 
 (i) “Acquisition”. For the purpose of this Warrant,
“Acquisition” means any sale, transfer, exclusive license, or other disposition of all or substantially all of the assets of the Company, or any acquisition, reorganization, consolidation or merger of the Company where the holders of the
Company’s outstanding voting equity securities immediately prior to the transaction beneficially own less than 50.01% of the outstanding voting equity securities of the surviving or successor entity immediately following the transaction. 

(ii) Assumption of Warrant. Upon the closing of any Acquisition, the successor or surviving entity shall assume the obligations of this
Warrant, and this Warrant shall be exercisable for the same securities and property as would be payable for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Exercise Price shall be adjusted accordingly, and the Exercise Price and number and class of Shares shall continue to be subject to adjustment from time to time in accordance with the provisions hereof. 

(iii) Company’s Agreement Upon Acquisition. Notwithstanding the understanding set forth in subsection (f) (ii) above, if, for
any reason, the obligations of this Warrant are not assumed by the successor or surviving entity, the Company shall purchase this Warrant on the closing date of the Acquisition for cash in an amount per Warrant share equal to the greater of
(i) five (5) times the Exercise Price, less the Exercise Price, or (ii) the excess (if any) of the Fair Market Value of a Warrant Share over the Exercise Price. The Fair Market Value of a Warrant Share shall be determined as set forth in
Section 2(c). 
 (g) Conversion or Redemption of Series B Preferred Shares. Should all of the Company’s Series B Preferred
Shares be, or if outstanding would be, at any time prior to the expiration of the Warrant or any portion thereof, redeemed or converted into the Company’s Common Shares in accordance with the Company’s Limited Liability Company Agreement
dated as of December 30, 2011 by and among the Company and the equity holders party thereto (as such may further be amended from time to time, the “LLC Agreement”), then this Warrant shall become immediately exercisable prior to such
event for that number of Common Shares that would have been received if this Warrant had been exercised in full and the Series B Preferred Shares received thereupon had been simultaneously converted immediately prior to such event, and the Exercise
Price shall immediately be adjusted to equal the quotient obtained by dividing (x) the aggregate Exercise Price of the maximum number of shares of Series B Preferred Shares for which this Warrant was exercisable immediately prior to such
conversion or redemption, by (y) the number of Common Shares for which this Warrant is exercisable immediately after such conversion or redemption.

 3. ADJUSTMENTS 

(a) Share Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding Preferred Shares,
payable in Common Shares or other Capital Securities (as defined in the LLC Agreement) of the Company, or subdivides the outstanding Preferred Shares into a greater amount of Preferred Shares, then upon exercise of this Warrant, for each Share
acquired, Holder shall receive, without cost to Holder, the total number and kind of Capital Securities of the Company to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend, distribution or
subdivision occurred. If the outstanding Preferred Shares are subdivided into a greater number of shares, the Exercise Price shall be proportionately decreased and the number of Shares shall be proportionately increased. 

(b) Reclassification, Exchange or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the Capital Securities of the Company issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise or conversion of this Warrant, the number and kind of Capital
Securities of the Company and property that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. The Company or its successor shall promptly
issue to Holder a new Warrant for such new Capital Securities of the Company or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this
Section 3 including, without limitation, adjustments to the Exercise Price and to the number of Capital Securities of the Company or property issuable upon exercise of the new Warrant. The provisions of this Section 3(b) shall similarly
apply to successive reclassifications, exchanges, substitutions, or other events. 
 (c) Adjustments for Combinations, Etc. If the
outstanding Common Shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Exercise Price shall be proportionately increased and the number of Shares shall be proportionately decreased. 

(d) No Impairment. The Company shall not, by amendment of its LLC Agreement, or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all
times in good faith assist in carrying out of all the provisions of this Section 3 and in taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article against impairment. 

  
 - 4 - 

 (e) Fractional Shares. No fractional Shares shall be issuable upon exercise or
conversion of the Warrant and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional Share interest arises upon any exercise or conversion of this Warrant, the Company shall eliminate such fractional
Share interest by paying Holder an amount computed by multiplying such fractional interest by the Fair Market Value (determined in accordance with Section 2(c) above) of one Share. 

(f) Certificate as to Adjustments. Upon each adjustment of the Exercise Price, number of Shares or class of security for which this
Warrant is exercisable, the Company at its expense shall promptly compute such adjustment, and furnish Holder with a certificate of its chief financial officer setting forth such adjustment and the facts upon which such adjustment is based. The
Company shall, upon written request, furnish Holder a certificate setting forth the Exercise Price, number of Shares class of security for which this Warrant is exercisable in effect upon the date thereof and the series of adjustments leading to
such Exercise Price, number of Shares and class of security. 
 4. REPRESENTATIONS AND COVENANTS OF THE COMPANY

all or substantially all of its assets, or to liquidate, dissolve or wind up; or (e) offer holders of registration rights the opportunity to participate in an underwritten public offering of the company’s Capital Securities for cash, then,
in connection with each such event, the Company shall give Holder (1) at least 45 days prior written notice of the date on which a record will be taken for such dividend, distribution, or subscription rights (and specifying the date on which
the holders of Capital Securities of the Company shall be entitled to receive such dividend, distribution or rights) or for determining rights to vote, if any, in respect of the matters referred to in (c) and (d) above; (2) in the case of
the matters referred to in (c) and (d) above at least 45 days prior written notice of the date when the same will take place (and specifying the date on which the holders of Capital Securities of the Company will be entitled to exchange their

Investors holding a majority of the Registrable Securities then outstanding as set forth in Section 2.10 of the Investors’ Rights Agreement to ensure Holder receives such registration rights. The Company represents and warrants to Holder
that the Company’s execution, delivery and performance of such Investors’ Rights Agreement (a) has been duly authorized by all necessary action of the Company’s Board of Directors and shareholders, (b) does not and will not
violate the LLC Agreement, (c) does not and will not violate or cause a breach or default (or an event which with the passage of time or the giving of notice or both, would constitute a breach or default) under any agreement, instrument,
mortgage, deed of trust or other arrangement to which the Company is a party or to or by which it or any of its assets is subject or bound, and (d) does not require the approval, consent or waiver of or by any shareholder, registration rights holder

that represent an investment in the Company and all of its subsidiaries as an enterprise (and not an investment that is linked to a specific subsidiary or sub-group of subsidiaries) for an issuance price less
than the then exercise price for the shares subject to this Warrant, this Warrant shall, concurrent with the issuance of such preferred shares pursuant to the new equity round, automatically be adjusted to instead be exercisable for shares of the
new series and new class of shares and bearing the same rights, preferences, and privileges of such new shares, with the Exercise Price hereunder adjusted to equal the per share purchase price of such share, and the number of such shares subject to
this Warrant adjusted to equal (i) $140,000, divided by (ii) such modified per share Exercise Price. 
 (b) Automatic Conversion upon
Expiration. In the event that, upon the Expiration Date, the Fair Market Value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 2(c) above is greater than the Exercise Price in
effect on such date, then this Warrant shall automatically be deemed on and as of such date to be converted pursuant to Section 2(b) above as to all Shares (or such other securities) for which it shall not previously have been exercised or
converted, and the Company shall promptly deliver a certificate representing the Shares (or such other securities) issued upon such conversion to the Holder. 

(c) Legends. This Warrant and the Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any)
shall be imprinted with one or more legends in substantially the following form: 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION
IS NOT REQUIRED. 
 (d) Compliance with Securities Laws on Transfer. This Warrant and the Shares (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) may not be transferred or assigned in whole or in part without compliance with applicable federal and state securities laws by the transferor and the transferee (including, without
limitation, the delivery of investment representation letters). The Company shall not require Holder to provide an opinion of counsel if the transfer is to an affiliate of Holder or if(a) there is no material question as to the availability of
current information as referenced in Rule 144(c), (b) Holder represents that it has complied with Rule 144(d) and (e) in reasonable detail, (c) the selling broker represents that it has complied with Rule 144(±), and (d) the

Holder, or to any other transferee by giving the Company notice of the portion of the Warrant being transferred setting forth the name, address and taxpayer identification number of the transferee and surrendering this Warrant to the Company for
reissuance to the transferee(s) (and Holder if applicable).

protect and enforce its rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any such default, and/or an action for specific performance for any default where Holder will not have
an adequate remedy at law and where damages will not be readily ascertainable. The Company expressly agrees that it shall not oppose an application by the Holder or any other person entitled to the benefit of this Warrant requiring specific
performance of any or all provisions hereof or enjoining the Company from continuing to commit any such breach of this Warrant.

	SECTION 2.	 ADMINISTRATION OF PLAN; ADMINISTRATOR AUTHORITY TO SELECT GRANTEES AND DETERMINE AWARDS

 (a)    Administration of Plan. The Plan shall be administered by the Administrator. 

  
 3 

 (b)    Powers of Administrator. The Administrator shall have the
power and authority to grant Awards consistent with the terms of the Plan, including the power and authority: 

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

(ii)    to determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Non-Qualified Stock Options, Stock Appreciation Rights, Restricted Stock Awards, Restricted Stock Units, Unrestricted Stock Awards, Cash-Based Awards, and Dividend Equivalent Rights, or any combination of the
foregoing, granted to any one or more grantees; 
 (iii)    to determine the number of shares of Stock to be covered by
any Award; 
 (iv)    to determine and modify from time to time the terms and conditions, including restrictions, not
inconsistent with the terms of the Plan, of any Award, which terms and conditions may differ among individual Awards and grantees, and to approve the forms of Award Certificates; 

(v)    to accelerate at any time the exercisability or vesting of all or any portion of any Award; 

(vi)    subject to the provisions of Section 5(c), to extend at any time the period in which Stock Options may be
exercised; and 
 (vii)    at any time to adopt, alter and repeal such rules, guidelines and practices for
administration of the Plan and for its own acts and proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for
the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan. 

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. Subject to applicable law, the Administrator, in its discretion,
may delegate to a committee consisting of one or more officers of the Company all or part of the Administrator’s authority and duties with respect to the granting of Awards to individuals who are (i) not subject to the reporting and other
provisions of Section 16 of the Exchange Act and (ii) not members of the delegated committee. Any such delegation by the Administrator shall include a limitation as to the amount of Stock underlying Awards that may be granted during the
period of the delegation and shall contain guidelines as to the determination of the exercise price 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)    Award Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms,
conditions and limitations for each Award which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service terminates. 

  
 4 

 (e)    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, damage or expense (including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to
the fullest extent permitted by law and/or under the Company’s articles or bylaws or any directors’ and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between such
individual and the Company. 
 (f)    Foreign Award Recipients. Notwithstanding any provision of the Plan to the
contrary, in order to comply with the laws in other countries in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the power and authority
to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to
individuals outside the United States to comply with applicable foreign laws; (iv) establish subplans 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 attached to this Plan as appendices); provided, however, that no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and
(v) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. 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. 
  

	SECTION 3.	 STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION 

(a)    Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan
shall be 3,436,632 shares (the “Initial Limit”), subject to adjustment as provided in this Section 3, plus on January 1, 2021 and each January 1 thereafter, the number of shares of Stock reserved and available for issuance
under the Plan shall be cumulatively increased by 4% of the number of shares of Stock issued and outstanding on the immediately preceding December 31 or such lesser amount as determined by the Administrator (the “Annual Increase”).
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, 2021 and on each
January 1 thereafter by the lesser of the Annual Increase for such year or 3,436,632 shares of Stock, subject in all cases to adjustment as provided in this Section 3. For purposes of this limitation, the shares of Stock underlying any
awards under the Plan and under the Company’s 2019 Stock Incentive Plan that are forfeited, canceled, held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding, reacquired by the Company prior
to vesting, satisfied without the issuance of Stock or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan and, to the extent permitted under Section 422 of the Code and
the regulations promulgated thereunder, the shares of Stock that may be issued as Incentive 

  
 5 

 
Stock Options. In the event the Company repurchases shares of Stock on the open market, such shares shall not be added to the shares of Stock available for issuance under the Plan. Subject to
such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired
by the Company. 
 (b)    Changes in Stock. Subject to Section 3(c) 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 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, including the maximum number
of shares that may be issued in the form of Incentive Stock Options, (ii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per share subject to
each outstanding Restricted Stock Award, and (iv) the exercise 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 shares subject to Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate
adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event.
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. 
 (c)    Mergers and Other Transactions. In the case of and subject to the consummation of a
Sale Event, 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 Sale Event do not provide for the assumption, continuation or substitution of Awards, upon the
effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall terminate. In such case, except as may be otherwise provided in the relevant Award Certificate, 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 Sale Event shall become fully vested and exercisable as of the effective time of the Sale Event, all other Awards with
time-based vesting, conditions or restrictions shall become fully vested and nonforfeitable as of the effective time of the Sale Event, and all Awards with conditions and restrictions relating to the attainment of performance goals may become vested
and nonforfeitable in connection with a Sale Event in the Administrator’s discretion or to the extent specified in the relevant Award Certificate. In the event of such termination, (i) the Company shall have the option

  
 6 

 
(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 Sale Price 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 Sale 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 Sale 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 Sale Event 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 Sale Price multiplied by the number of vested shares of Stock under such Awards. 

(d)    Maximum Awards to Non-Employee 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 Non-Employee Director in any calendar year shall not exceed (i)
$1,000,000 in the first calendar year the applicable Non-Employee Director is initially elected or appointed to the Board, and (ii) $750,000 in any other year (or in such case, such other limits as may be set
forth in Section 3(b) of the Plan or any similar provision of a successor plan). For the purpose of this limitation, the value of any Award shall be its grant date fair value, as determined in accordance with ASC 718 or successor provision but
excluding the impact of estimated forfeitures related to service-based vesting provisions.  
  

	SECTION 4.	 ELIGIBILITY 

Grantees under the Plan will be such employees, Non-Employee Directors or Consultants of the Company
and its Affiliates as are selected from time to time by the Administrator in its sole discretion; provided that Awards may not be granted to employees, Directors or Consultants who are providing services only to any “parent” of the
Company, as such term is defined in Rule 405 of the Act, unless (i) the stock underlying the Awards is treated as “service recipient stock” under Section 409A or (ii) the Company has determined that such Awards are exempt
from or otherwise comply with Section 409A. 
  

	SECTION 5.	 STOCK OPTIONS 

(a)    Award of Stock Options. The Administrator may grant Stock Options under the Plan. Any Stock Option granted
under the Plan shall be in such form as the Administrator may from time to time approve. 
 Stock Options granted under the Plan may be
either Incentive Stock Options or Non-Qualified 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 any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. 

  
 7 

 Stock Options granted pursuant to this Section 5 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. 

(b)    Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to
this Section 5 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 date of grant. In the case of an Incentive Stock Option that is granted to a Ten Percent
Owner, the exercise price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date. Notwithstanding the foregoing, Stock Options may be granted with an exercise price per share that is less
than 100 percent of the Fair Market Value on the date of grant (i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to individuals who are not subject to U.S. income tax on
the date of grant or (iii) the Stock Option is otherwise compliant with Section 409A. 
 (c)    Option
Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten
Percent Owner, the term of such Stock Option shall be no more than five years from the date of grant. 

(d)    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. 

(e)    Method of Exercise. Stock Options may be exercised in whole or in part, by giving written or electronic
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 except to the extent otherwise provided in the Award Certificate: 

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

(ii)    Through the delivery (or attestation to the ownership following such procedures as the Company may prescribe) 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; 

(iii)    By the optionee delivering 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 Company shall prescribe as a condition of such payment procedure; or 

  
 8 

 (iv)    With respect to Stock Options that are not Incentive Stock
Options, 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. 
 Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or
of the transfer agent 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 Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is
obligated to withhold with respect to the optionee). 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 attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using
an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use of such an automated system. 

(f)    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 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
Non-Qualified Stock Option. 
  

	SECTION 6.	 STOCK APPRECIATION RIGHTS 

(a)    Award of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan. A
Stock Appreciation Right is an Award entitling the recipient to receive shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate) having a value equal to the excess of the Fair Market Value of a share of
Stock on the date of exercise over the exercise 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. 

(b)    Exercise Price of Stock Appreciation Rights. The exercise price of a Stock Appreciation Right shall not be
less than 100 percent of the Fair Market Value of the Stock on the date of grant. 
 (c)    Grant and Exercise
of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any Stock Option granted pursuant to Section 5 of the Plan. 

(d)    Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms
and conditions as shall be determined on the date of grant by the 

  
 9 

 
Administrator. The term of a Stock Appreciation Right may not exceed ten years. 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 7.	 RESTRICTED STOCK AWARDS 

(a)    Nature of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan. A
Restricted Stock Award is any Award of Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing employment (or other Service Relationship) and/or
achievement of pre-established performance goals and objectives. 

(b)    Rights as a Stockholder. Upon the grant of 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 Shares and receipt of dividends; provided that if the lapse of restrictions with respect to the Restricted Stock Award is tied to the attainment of
performance goals, any dividends paid by the Company during the performance period shall accrue and shall not be paid to the grantee until and to the extent the performance goals are met with respect to the Restricted Stock Award. Unless the
Administrator shall otherwise determine, (i) uncertificated Restricted Shares shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture until such Restricted Shares
are vested as provided in Section 7(d) below, and (ii) certificated Restricted Shares shall remain in the possession of the Company until such Restricted Shares are vested as provided in Section 7(d) below, and the grantee shall be
required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe. 

(c)    Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or
disposed of except as specifically provided herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing after the
Award is issued, if a grantee’s employment (or other Service Relationship) with the Company and its Subsidiaries terminates for any reason, any Restricted Shares that have not vested at the time of termination shall automatically and without
any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee’s legal representative
simultaneously with such termination of employment (or other Service Relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of
Restricted Shares that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration. 

(d)    Vesting of Restricted Shares. 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 Shares 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.” 

  
 10 

	SECTION 8.	 RESTRICTED STOCK UNITS 

(a)    Nature of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan. A
Restricted Stock Unit is an Award of stock units that may be settled in shares of Stock (or cash, to the extent explicitly provided for in the Award Certificate) upon the satisfaction of such restrictions and conditions at the time of grant.
Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives. 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. Except in the case of Restricted Stock Units with a deferred settlement date that complies with Section 409A, 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. Restricted Stock Units with deferred settlement dates are subject to Section 409A and shall contain such additional terms and
conditions as the Administrator shall determine in its sole discretion in order to comply with the requirements of Section 409A. 

(b)    Election to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole
discretion, permit a grantee to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of an award of Restricted Stock Units. Any such election shall be made in writing and shall be delivered to the Company
no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures established by the Administrator. Any such future cash compensation that the grantee elects to defer shall be
converted to a fixed number of Restricted Stock Units based on the Fair Market Value of Stock on the date the compensation would otherwise have been paid to the grantee if such payment had not been deferred as provided herein. The Administrator
shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. Any Restricted Stock Units that are
elected to be received in lieu of cash compensation shall be fully vested, unless otherwise provided in the Award Certificate. 

(c)    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 stock units underlying his Restricted Stock Units, subject to the provisions
of Section 11 and such terms and conditions as the Administrator may determine. 
 (d)    Termination.
Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing after the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall
automatically terminate upon the grantee’s termination of employment (or cessation of Service Relationship) with the Company and its Subsidiaries for any reason. 
  

	SECTION 9.	 UNRESTRICTED STOCK AWARDS 

Grant or Sale of Unrestricted Stock. The Administrator may grant (or sell at par value or such higher purchase price determined by the
Administrator) an Unrestricted Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive 

  
 11 

 
shares of Stock free of any restrictions under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to
such grantee. 
  

	SECTION 10.	 CASH-BASED AWARDS 

Grant of Cash-Based Awards. The Administrator may grant Cash-Based Awards under the Plan. A Cash-Based Award is an Award that entitles
the grantee to a payment in cash upon the attainment of specified performance goals. The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash to which the Cash-Based Award pertains, the conditions upon which
the Cash-Based Award shall become vested or payable, and such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or payment ranges as determined by the Administrator.
Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of the Award and may be made in cash. 
  

	SECTION 11.	 DIVIDEND EQUIVALENT RIGHTS 

(a)    Dividend Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend
Equivalent Right is an Award entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right (or other Award to which it relates) if such shares had been
issued to the grantee. A Dividend Equivalent Right may be granted hereunder to any grantee as a component of an award of Restricted Stock Units or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in
the Award Certificate. 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 an Award of Restricted Stock Units shall provide that such Dividend Equivalent Right shall be settled only upon 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. 

(b)    Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or,
subject to Section 16 below, in writing after the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s termination of employment (or cessation of Service Relationship)
with the Company and its Subsidiaries for any reason. 
  

	SECTION 12.	 TRANSFERABILITY OF AWARDS 

(a)    Transferability. Except as provided in Section 12(b) below, during a grantee’s lifetime, his or her
Awards shall be exercisable only by the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, 

  
 12 

 
assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall
be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void. 

(b)    Administrator Action. Notwithstanding Section 12(a), the Administrator, in its discretion, may provide
either in the Award Certificate regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Stock Options to his or her
immediate family members, to trusts for the benefit of such family 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. In no event may an Award be transferred by a grantee for value. 

(c)    Family Member. For purposes of Section 12(b), “family member” shall mean a grantee’s
child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the
grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50 percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of
assets, and any other entity in which these persons (or the grantee) own more than 50 percent of the voting interests. 

(d)    Designation of Beneficiary. To the extent permitted by the Company, each grantee to whom an Award has been
made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the
Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s
estate. 
  

	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 includable in the gross income of the grantee for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any Federal,
state, or local taxes of any kind required by law to be withheld by the Company 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 evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee. 

(b)    Payment in Stock. The Administrator may require the Company’s tax withholding obligation to be
satisfied, in whole or in part, by the Company 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 the withholding
amount due; provided, 

  
 13 

 
however, that the amount withheld does not exceed the maximum statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment. For purposes of share withholding,
the Fair Market Value of withheld shares shall be determined in the same manner as the value of Stock includible in income of the grantees. The Administrator may also require the Company’s tax withholding obligation to be satisfied, in whole or
in part, by an arrangement whereby a certain number of shares of Stock issued pursuant to any Award are immediately sold and proceeds from such sale are remitted to the Company in an amount that would satisfy the withholding amount due. 

 

	SECTION 14.	 SECTION 409A AWARDS 

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A. The
Plan and all Awards shall be interpreted in accordance with such intent. 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 except to the extent permitted by Section 409A. 
  

	SECTION 15.	 TERMINATION OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC. 

(a)    Termination of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such
Affiliate ceases to be an Affiliate, the grantee shall be deemed to have terminated his or her Service Relationship for purposes of the Plan. 

(b)    For purposes of the Plan, the following events shall not be deemed a termination of a Service Relationship: 

(i)    a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one
Affiliate to another; or 
 (ii)    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 16.	 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 materially and adversely affect rights under 

  
 14 

 
any outstanding Award without the holder’s consent. The Administrator is specifically authorized to exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock
Appreciation Rights or effect the repricing of such Awards through cancellation and re-grants. To the extent required under the rules of any securities exchange or market system on which the Stock is listed,
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 Company
stockholders. Nothing in this Section 16 shall limit the Administrator’s authority to take any action permitted pursuant to Section 3(b) or 3(c). 
  

	SECTION 17.	 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 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 18.	 GENERAL PROVISIONS 

(a)    No Distribution. 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. 

(b)    Issuance of Stock. To the extent certificated, stock certificates to grantees under this Plan 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). Notwithstanding anything herein to the contrary, the
Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing shares of Stock pursuant to the exercise or settlement of any Award, unless and until the Administrator has determined, with advice of counsel
(to the extent the Administrator deems such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on
which the shares of Stock are listed, quoted or traded. Any Stock issued pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with federal, state or
foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate or notations on any book entry to reference restrictions
applicable to the Stock. 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,

  
 15 

 
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. 

(c)    Stockholder Rights. Until Stock is deemed delivered in accordance with Section 18(b), no right to vote
or receive dividends or any other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other action by the grantee with respect to an
Award. 
 (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 the Company’s insider trading policies and procedures, as in effect from time to time. 

(f)    Clawback Policy. Awards under the Plan shall be subject to the Company’s clawback policy, as in effect
from time to time. 
  

	SECTION 19.	 EFFECTIVE DATE OF PLAN 

This Plan shall become effective upon the date immediately preceding the Registration Date 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 20.	 GOVERNING LAW 

This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the General Corporation Law of
the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of the State of Delaware, applied without regard to conflict of law principles.

 Pursuant to the Forma Therapeutics Holdings, Inc. 2020 Stock Option and Incentive Plan as amended through the
date hereof (the “Plan”), Forma Therapeutics Holdings, Inc. (the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified above all or
part of the number of shares of Common Stock, par value $0.001 per share (the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the
Plan. 
 1.    Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall
have become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option shall be exercisable with
respect to the following number of Option Shares as follows: 25% of the Option Shares shall vest and become exercisable on the first anniversary of the Vesting Commencement Date, and the remaining 75% of the Option Shares shall vest and become
exercisable in 36 equal monthly installments thereafter, in each case subject to the Optionee’s continued Service Relationship to the Company or a Subsidiary through each such date. 

Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration
Date, subject to the provisions hereof and of the Plan. 
 2.    Manner of Exercise. 

(a)    The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the
Expiration Date of this Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of
Option Shares to be purchased. 

 Payment of the purchase price for the Option Shares may be made by one or more of the
following methods: (i) in cash, by certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the
open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; or (iii) by the Optionee
delivering 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 to pay the option purchase price, provided that
in the event the Optionee chooses to pay the option 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; or (iv) a combination of (i), (ii) and (iii) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the
Company’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent
resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the 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 Shares attested to. 
 (b)    The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable
laws or regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be
the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent
shall have transferred the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership rights
with respect to such shares of Stock. 
 (c)    The minimum number of shares with respect to which this Stock Option may
be exercised at any one time shall be 100 shares, unless the number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

 

  
 2 

 (d)    Notwithstanding any other provision hereof or of the Plan, no
portion of this Stock Option shall be exercisable after the Expiration Date hereof. 
 3.    Termination of Service
Relationship. If the Optionee’s Service Relationship with the Company or a Subsidiary (as defined in the Plan) terminates, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a)    Termination Due to Death. If the Optionee’s Service Relationship with the Company or a Subsidiary
terminates by reason of the Optionee’s death, any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a
period of 12 months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of no further force or effect. 

(b)    Termination Due to Disability. If the Optionee’s Service Relationship with the Company or a Subsidiary
terminates by reason of the Optionee’s disability (as determined by the Administrator), any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination, may thereafter be exercised by the
Optionee for a period of 12 months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate immediately and be of no further force or
effect. 
 (c)    Termination for Cause. If the Optionee’s Service Relationship with the Company or a
Subsidiary terminates for Cause, any portion of this Stock Option outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an
employment or service agreement between the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement between the Optionee
and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate
non-performance (other than by reason of disability) by the Optionee of the Optionee’s duties to the Company. 

(d)    Other Termination. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates
for any reason other than the Optionee’s death, the Optionee’s disability, or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent
exercisable on the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of termination shall terminate
immediately and be of no further force or effect. 
 The Administrator’s determination of the reason for termination of the
Optionee’s Service Relationship with the Company or a Subsidiary shall be conclusive and binding on the Optionee and his or her representatives or legatees. 
  

  
 3 

 4.    Incorporation of Plan. Notwithstanding anything herein to
the contrary, this Stock Option shall be subject to and governed by all the terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein. 
 5.    Transferability. This
Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option
is exercisable, during the Optionee’s lifetime, only by the Optionee, and thereafter, only by the Optionee’s legal representative or legatee. 

6.    Status of the Stock Option. This Stock Option is intended to qualify as an “incentive stock option”
under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), but the Company does not represent or warrant that this Stock Option qualifies as such. The Optionee should consult with his or her own tax advisors
regarding the tax effects of this Stock Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to, holding period requirements and that this Stock Option
must be exercised within three months after termination of employment as an employee (or 12 months in the case of death or disability) to qualify as an “incentive stock option.” To the extent any portion of this Stock Option does
not so qualify as an “incentive stock option,” such portion shall be deemed to be a non-qualified stock option. If the Optionee intends to dispose or does dispose (whether by sale, gift, transfer or
otherwise) of any Option Shares within the one-year period beginning on the date after the transfer of such shares to him or her, or within the two-year period beginning
on the day after the grant of this Stock Option, he or she will so notify the Company within 30 days after such disposition. Further, to the extent this Stock Option and any other incentive stock options of the Optionee having an aggregate fair
market value in excess of $100,000 (determined as of the grant date of such options) first become exercisable in any year, such options will not qualify as incentive stock options. 

7.    Tax Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option
becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event.
The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in whole or in part, by (i) withholding from shares of Stock to be issued to the Optionee a number of shares of Stock with an aggregate Fair
Market Value that would satisfy the withholding amount due; or (ii) causing its transfer agent to sell from the number of shares of Stock to be issued to the Optionee, the number of shares of Stock necessary to satisfy the Federal, state and
local taxes required by law to be withheld from the Optionee on account of such transfer. 
 8.    No Obligation to
Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue the Optionee’s Service Relationship with the Company or a Subsidiary and neither the Plan nor
this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the Optionee’s Service Relationship with the Company or a Subsidiary at any time. 

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

  
 4 

 10.    Data Privacy Consent. In order to administer the Plan and
this Agreement and to implement or structure future equity grants, the Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data,
including but not limited to Social Security or other identification number, home address and telephone number, date of birth and other information that is necessary or desirable for the administration of the Plan and/or this Agreement (the
“Relevant Information”). By entering into this Agreement, the Optionee (i) authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the
Optionee may have with respect to the Relevant Information; (iii) authorizes the Relevant Companies to store and transmit such information in electronic form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction
in which the Relevant Companies consider appropriate. The Optionee shall have access to, and the right to change, the Relevant Information. Relevant Information will only be used in accordance with applicable law. 

 

  
 5 

 11.    Notices. Notices hereunder shall be mailed or delivered to
the Company at its principal place of business and shall be mailed or delivered to the Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing.

 Pursuant to the Forma Therapeutics Holdings, Inc. 2020 Stock Option and Incentive Plan as amended through the
date hereof (the “Plan”), Forma Therapeutics Holdings, Inc. (the “Company”) hereby grants to the Optionee named above, who is a Non-Employee Director of the Company but is not an employee

share (the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the Plan. This Stock Option is not intended to be an “incentive
stock option” under Section 422 of the Internal Revenue Code of 1986, as amended. 
 1.    Exercisability
Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate
the exercisability schedule hereunder, this Stock Option shall be exercisable with respect to the following number of Option Shares as follows: [FOR INITIAL GRANTS: 33.3% of the Option Shares shall vest and become exercisable on the first
anniversary of the Vesting Commencement Date, and the remaining 66.7% of the Option Shares shall vest and become exercisable in 24 equal monthly installments thereafter, subject in each case to the Optionee’s continued Service Relationship to
the Company through each such date.] [FOR ANNUAL GRANTS: the Option Shares shall vest in full upon the earlier to occur of the first anniversary of the Grant Date or the date of the Company’s next Annual Meeting of Stockholders, subject to the
Optionee’s continued Service Relationship to the Company through each such date.] 
 Once exercisable, this Stock Option shall continue
to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of the Plan. Notwithstanding the foregoing, 100% of the Option Shares shall become exercisable immediately prior to
the consummation of a Sale Event, provided that the Grantee continues to 
  

  
 7 

 
maintain a Service Relationship with the Company through the date of such Sale Event. Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close
of business on the Expiration Date, subject to the provisions hereof and of the Plan. 
 2.    Manner of Exercise.

 (a)    The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the
Expiration Date of this Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of
Option Shares to be purchased. 
 Payment of the purchase price for the Option Shares may be made by one or more of the following methods:
(i) in cash, by certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that
are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee delivering 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 to pay the option purchase price, provided that in the event the Optionee
chooses to pay the option 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; (iv) 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 (v) a combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the
Company’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent
resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the 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 Shares attested to. 
 (b)    The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable
laws or regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be
the holder of, or to have any of the rights of a 
  

  
 8 

 
holder with respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer
agent shall have transferred the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership
rights with respect to such shares of Stock. 
 (c)    The minimum number of shares with respect to which this Stock
Option may be exercised at any one time shall be 100 shares, unless the number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d)    Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable
after the Expiration Date hereof. 
 3.    Termination of Service Relationship. If the Optionee ceases to
maintain a continuous Service Relationship with the Company, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a)    Termination Due to Death. If the Optionee’s Service Relationship terminates by reason of the
Optionee’s death, any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 months from the
date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of no further force or effect. 

(b)    Other Termination. If the Optionee ceases to maintain a continuous Service Relationship with the Company for
any reason other than the Optionee’s death, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on the date the Optionee ceased to maintain a continuous Service Relationship with the Company,
for a period of 12 months from the date the Optionee ceased to maintain a continuous Service Relationship with the Company or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date the Optionee
ceases to maintain a Service Relationship with the Company shall terminate immediately and be of no further force or effect. 

4.    Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to
and governed by all the terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different
meaning is specified herein. 
 5.    Transferability. This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s
lifetime, only by the Optionee, and thereafter, only by the Optionee’s legal representative or legatee. 

6.    No Obligation to Continue Service Relationship. Neither the Plan nor this Stock Option confers upon the
Optionee any rights with respect to continuance as a Non-Employee Director or other Service Relationship. 
  

  
 9 

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

8.    Tax Withholding.    To the extent applicable, the Optionee shall, not later than the date
as of which the receipt of this Award becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be
withheld on account of such taxable event. The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in whole or in part, by (i) withholding from shares of Stock to be issued to the Optionee a number
of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding amount due; or (ii) causing its transfer agent to sell from the number of shares of Stock to be issued to the Optionee, the number of shares of Stock

 Pursuant to the Forma Therapeutics Holdings, Inc. 2020 Stock Option and Incentive Plan as amended through the
date hereof (the “Plan”), Forma Therapeutics Holdings, Inc. (the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified above all or
part of the number of shares of Common Stock, par value $0.001 per share (the “Stock”) of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the
Plan. This Stock Option is not intended to be an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended. 

1.    Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have
become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option shall be exercisable with respect to
the following number of Option Shares as follows: 25% of the Option Shares shall vest and become exercisable on the first anniversary of the Vesting Commencement Date, and the remaining 75% of the Option Shares shall vest and become exercisable in
36 equal monthly installments thereafter, in each case subject to the Optionee’s continued Service Relationship to the Company or a Subsidiary through each such date. 

Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration
Date, subject to the provisions hereof and of the Plan. 
 2.    Manner of Exercise. 

(a)    The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the
Expiration Date of this Stock Option, the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of
Option Shares to be purchased. 

  
 12 

 Payment of the purchase price for the Option Shares may be made by one or more of the
following methods: (i) in cash, by certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the
open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee
delivering 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 to pay the option purchase price, provided that
in the event the Optionee chooses to pay the option 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; (iv) 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 (v) a combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the
Company’s receipt from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any subsequent
resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the 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 Shares attested to. 
 (b)    The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon compliance to the satisfaction of the Administrator with all requirements under applicable
laws or regulations in connection with such transfer and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be
the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent
shall have transferred the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership rights
with respect to such shares of Stock. 
 (c)    The minimum number of shares with respect to which this Stock Option may
be exercised at any one time shall be 100 shares, unless the number of shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

  
 13 

 (d)    Notwithstanding any other provision hereof or of the Plan, no
portion of this Stock Option shall be exercisable after the Expiration Date hereof. 
 3.    Termination of Service
Relationship. If the Optionee’s Service Relationship with the Company or a Subsidiary (as defined in the Plan) terminates, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a)    Termination Due to Death. If the Optionee’s Service Relationship with the Company or a Subsidiary
terminates by reason of the Optionee’s death, any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a
period of 12 months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall terminate immediately and be of no further force or effect. 

(b)    Termination Due to Disability. If the Optionee’s Service Relationship with the Company or a Subsidiary
terminates by reason of the Optionee’s disability (as determined by the Administrator), any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination, may thereafter be exercised by the
Optionee for a period of 12 months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of disability shall terminate immediately and be of no further force or
effect. 
 (c)    Termination for Cause. If the Optionee’s Service Relationship with the Company or a
Subsidiary terminates for Cause, any portion of this Stock Option outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an
employment or other service agreement between the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement between the Optionee
and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate
non-performance (other than by reason of disability) by the Optionee of the Optionee’s duties to the Company. 

(d)    Other Termination. If the Optionee’s Service Relationship with the Company or a Subsidiary terminates
for any reason other than the Optionee’s death, the Optionee’s disability or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable
on the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of termination shall terminate immediately and be of
no further force or effect. 
 The Administrator’s determination of the reason for termination of the Optionee’s Service
Relationship with the Company or a Subsidiary shall be conclusive and binding on the Optionee and his or her representatives or legatees. 

  
 14 

 4.    Incorporation of Plan. Notwithstanding anything herein to
the contrary, this Stock Option shall be subject to and governed by all the terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein. 
 5.    Transferability. This
Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option
is exercisable, during the Optionee’s lifetime, only by the Optionee, and thereafter, only by the Optionee’s legal representative or legatee. 

6.    Tax Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option
becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event.
The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in whole or in part, by (i) withholding from shares of Stock to be issued to the Optionee a number of shares of Stock with an aggregate Fair
Market Value that would satisfy the withholding amount due; or (ii) causing its transfer agent to sell from the number of shares of Stock to be issued to the Optionee, the number of shares of Stock necessary to satisfy the Federal, state and
local taxes required by law to be withheld from the Optionee on account of such transfer. 
 7.    No Obligation to
Continue Service Relationship. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue the Optionee’s Service Relationship with the Company or a Subsidiary and neither the Plan nor
this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the Optionee’s Service Relationship with the Company or a Subsidiary at any time. 

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

9.    Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future
equity grants, the Company, its subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including but not limited to Social Security or other
identification number, home address and telephone number, date of birth and other information that is necessary or desirable for the administration of the Plan and/or this Agreement (the “Relevant Information”). By entering into this
Agreement, the Optionee (i) authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the Optionee may have with respect to the Relevant
Information; (iii) authorizes the Relevant Companies to store and transmit such information in electronic form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant Companies consider
appropriate. The Optionee shall have access to, and the right to change, the Relevant Information. Relevant Information will only be used in accordance with applicable law.
