number of fully paid and nonassessable shares of Common Stock as is initially equal to one and three quarters percent (1.75%) of the shares of Common Stock outstanding on a Fully Diluted Basis as of the earlier of a Date of Exercise and the IPO
Date, as provided more fully in Section 4.02. 
 (b) Promptly following the IPO Date, the Company shall prepare and deliver
to the Holder a notice executed by an Officer of the Company setting forth the number of shares of Common Stock outstanding on a Fully Diluted Basis at the close of business on the IPO Date and the number of Warrant Shares available for issuance
under the Warrants, if any, on and after the IPO Date. 
 SECTION 2.02. Representations and Warranties of the Company.
The Company hereby represents and warrants, on the date hereof, as follows: 
 (a) The Company is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware and has the requisite power and authority 

  
 3 

 
to execute and deliver this Agreement and the Warrant Certificates, to issue the Warrants and the Warrant Shares and to perform its obligations under this Agreement and the Warrant Certificates.

 (b) The execution, delivery and performance by the Company of this Agreement and the Warrant Certificates, the issuance of
the Warrants and the issuance of the Warrant Shares upon exercise of the Warrants have been duly authorized by all necessary corporate or similar action. 
 (c) This Agreement and the Warrant Certificates have been duly executed and delivered by the Company and each constitutes a legal, valid, binding and enforceable obligation of the Company, except to the
extent limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium and similar laws of general application related to the enforcement of creditor’s rights generally and (ii) general principles of equity. The Warrant
Shares, when issued upon exercise of the Warrants in accordance with the terms thereof and this Agreement, shall be duly authorized, validly issued, fully paid and nonassessable shares of Common Stock with no liability on the part of the holders
thereof, and shall be free from all taxes, liens, security interests, encumbrances, preemptive rights and charges. 
 SECTION

with the view to, or for resale in connection with, any distribution thereof. The Holder understands that the Warrants have not been registered under the Securities Act and, therefore, cannot be resold unless they are registered under the Securities
Act or unless an exemption from registration is available. 
 (c) The Holder understands that no public market now exists for
any of the securities issued by the Company and that the Company has made no assurances that a public market will ever exist for the Company’s securities.

 SECTION 3.02. Forms of Warrant Certificates. The Warrant Certificates shall be issued
in the form of Exhibit A attached hereto, together with the form of the election to purchase (the “Election to Purchase”) and assignment to be attached thereto, and, in addition, may have such letters, numbers or other marks
of identification or designation and such legends, summaries, or endorsements stamped, printed, lithographed or engraved thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as, in any
particular case, may be required in the opinion of counsel for the Company to comply with any law or with any rule or regulation of any regulatory authority or agency, or to conform to customary usage. Concurrently with the execution and delivery of
this Agreement, a Warrant Certificate for the Warrant being issued hereby shall be issued to Bayer. 
 SECTION 3.03.
Execution of Warrant Certificates. The Warrant Certificates shall be executed on behalf of the Company by an Officer thereof, either manually or by facsimile signature printed thereon. In case any Officer of the Company who shall have signed
any of the Warrant Certificates shall cease to be an Officer of the Company either before or after delivery thereof by the Company to any Holder, the signature of such Person on such Warrant Certificates shall be valid nevertheless and such Warrant
Certificates may be issued and delivered to those persons entitled to receive the Warrants represented thereby with the same force and effect as though the Person who signed such Warrant Certificates had not ceased to be an Officer of the Company.

 SECTION 3.04. Registration of Warrant Certificates. The Company shall number and keep a registry of the Warrant
Certificates in a register as they are needed. The Company may deem and treat registered Holders as the absolute owners thereof for all purposes. 
 SECTION 3.05. Exchange and Transfer of Warrant Certificates.

upon its face the following words: 
 NEITHER THE SECURITY REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES ISSUABLE UPON
EXERCISE HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY JURISDICTION. THIS SECURITY AND THE SECURITIES ISSUABLE UPON ITS EXERCISE MAY NOT BE OFFERED, SOLD, TRANSFERRED,
PLEDGED, ASSIGNED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO (I) A REGISTRATION STATEMENT WITH RESPECT TO SUCH SECURITIES THAT IS EFFECTIVE UNDER SUCH ACT OR APPLICABLE STATE SECURITIES LAW OR (II) ANY EXEMPTION FROM
REGISTRATION UNDER SUCH ACT, OR APPLICABLE STATE SECURITIES LAW, RELATING TO 

  
 5 

 
THE DISPOSITION OF SECURITIES, INCLUDING RULE 144, AND, IF REQUESTED BY THE COMPANY, AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY OPINING AS TO SUCH EXEMPTION. 

THIS SECURITY IS SUBJECT TO THE PROVISIONS OF THE WARRANT AGREEMENT, DATED AS OF MARCH 26, 2007, BETWEEN THE COMPANY AND BAYER SCHERING
PHARMA AG. A COPY OF SUCH WARRANT AGREEMENT IS AVAILABLE AT THE OFFICES OF THE COMPANY. 
 (b) The Warrant Certificate
representing the Warrant issued hereby may be transferred or assigned by the Holder hereof, in whole or in part as to any unexercised portion of the Exercise Percentage; provided that: (i) for transfers made to a Person other than an
Affiliate of the Holder, written notice is given to the Company at least ten (10) Business Days before the transfer and the transferor shall provide, at the Company’s request, an opinion of counsel reasonably satisfactory to the Company
that such transfer does not require registration under the Securities Act, (ii) the transfer shall be for a portion of the Warrant Certificate not less than the Minimum Exercise Threshold, (iii) the Holder shall provide written notice to
the Company of any transfer to an Affiliate within ten (10) Business Days after the transfer and (iv) the transferee shall agree to be bound by the terms of this Agreement. For purposes of Section 3.05(b)(i), Affiliate shall not
include any Person which is an individual. Written notice given under this Section 3.05(b) shall include without limitation the name of the transferee, the Exercise Percentage transferred to such transferee, the date of the transfer and the
transferee’s address for notice purposes. 
 (c) The Company shall from time to time note the permitted transfer of any
outstanding Warrant Certificates in a warrant register to be maintained by the Company upon surrender thereof accompanied by a written instrument or instruments of transfer in form satisfactory to the Company duly executed by the Holder or Holders
thereof or by the duly appointed legal representative thereof or by a duly authorized attorney. Upon any such registration of transfer, a new Warrant Certificate or Warrant Certificates will be issued to (x) the transferee representing a
Warrant for the Exercise Percentage specified in the foregoing written notice in accordance with instructions in the form of assignment and (y) the transferor representing a Warrant for the remaining Exercise Percentage not transferred, if any.

 (d) Warrant Certificates may be exchanged at the option of the Holder(s) thereof when surrendered to the Company at the
address set forth in Section 6.10 hereof for another Warrant Certificate or Warrant Certificates of like tenor and representing in the aggregate a Warrant or Warrants for a like Exercise Percentage. 

SECTION 3.06. Mutilated, Lost, Stolen or Destroyed Warrant Certificates. If any Warrant Certificate shall be mutilated, lost,
stolen or destroyed, the Company shall issue, execute and deliver, in exchange and substitution for and upon cancellation of a mutilated Warrant Certificate, or in lieu of or in substitution for a lost, stolen or destroyed Warrant Certificate, a new
Warrant Certificate representing a Warrant for an equivalent Exercise Percentage. The Holder of the mutilated, lost, stolen or destroyed Warrant Certificates must provide reasonable 

  
 6 

 
indemnity sufficient to protect the Company from any loss which it may suffer if the Warrant Certificate is replaced; it being understood and agreed that, in the case of Bayer or any of its
Affiliates, its written agreement to indemnify, shall be sufficient. Any such new Warrant Certificate shall constitute an original contractual obligation of the Company, whether or not the allegedly mutilated, lost, stolen or destroyed Warrant
Certificate shall be at any time enforceable by anyone. The mutilated, lost, stolen or destroyed Warrant Certificate that has been substituted shall no longer be valid. 
 SECTION 3.07. Cancellation of Warrant Certificates. Any Warrant Certificate surrendered upon the exercise of a Warrant or for exchange or transfer shall be canceled and shall not be reissued by the
Company; and, except as provided in Section 4.04 hereof in case of the exercise of less than the whole Warrant evidenced by a Warrant Certificate or in Section 3.05 in an exchange or transfer, no Warrant Certificate shall be issued
hereunder in lieu of such canceled Warrant Certificate. Any Warrant Certificate so canceled shall be destroyed by the Company. 

ARTICLE IV 

WARRANT EXERCISE PRICE AND EXERCISE OF WARRANTS 
 SECTION 4.01. Exercise Price. Each Warrant Certificate shall, when signed by an Officer of the Company, entitle the Holder thereof to purchase from the Company, subject to the terms and conditions
of this Agreement, the number of fully paid and nonassessable Warrant Shares evidenced thereby at a purchase price of $0.01 per share or such adjusted number of Warrant Shares at such adjusted purchase price as may be established from time to time
pursuant to the provisions of Article V hereof (the initial purchase price, as so adjusted, if applicable, the “Exercise Price”), payable in full in accordance with Section 4.02 hereof, at the time of exercise of the Warrant.

 SECTION 4.02. Exercise of Warrants. (a) The Warrant(s) shall be exercisable at any time or from time to time from
the date of issuance until the Expiration Date. Each Warrant shall be exercisable for the number of Warrant Shares equal to the Exercise Amount calculated based on the Exercise Percentage specified therein, subject, in each case, to the adjustments
set forth in Article V. The Warrant(s) may be exercised in whole or in part as to any permitted Exercise Percentage. The Exercise Amount for each exercise of a Warrant shall be calculated using the following formula: 

Exercise Amount = 

(1.75% * E * N) 

Divided by 

[1-1.75%*(A+R)] 
 Where:

  

	E =	Exercise Percentage being exercised by Holder 

  
 7 

	N =	Number of shares of Common Stock outstanding on a Fully Diluted Basis before exercise of the Warrant, not including outstanding Warrants issued hereunder

  

	A =	Aggregate Exercise Percentage held by exercising Holder before exercise of the Warrant 

 

	R =	Remaining Exercise Percentage held by all other Holders (not including the exercising Holder) 

 

	* =	Multiplied by 

 ; provided that
(i) the number of shares of Common Stock outstanding on a Fully Diluted Basis before exercise of the Warrant, not including outstanding Warrants issued hereunder and (ii) the summation of (A + R), each shall become fixed as of the IPO
Date. 
 (b) The Warrants may be exercised by surrendering the Warrant Certificates representing such Warrants to the Company at
its address set forth in Section 6.10 hereof, together with the Election to Purchase and an Investment Representation Statement substantially in the form attached as Exhibit B hereto, both duly completed and executed, accompanied by
payment in full, as set forth in Section 4.02(c), to the Company of the Exercise Price for each Warrant Share in respect of which such Warrants are being exercised. 
 (c) The Exercise Price shall be paid in full: (i) by certified check or wire transfer in same day funds in an amount equal to the Exercise Price multiplied by the number of Warrant Shares then being
purchased, (ii) by cancellation of a number of the Warrant Shares otherwise issuable to the Holder, such that the excess of the aggregate current Fair Market Value of such specified number of Warrant Shares on the Date of Exercise over the
portion of the Exercise Price attributable to such specified number of Warrant Shares shall equal the aggregate Exercise Price attributable to the Warrant Shares to be issued or (iii) by a combination of the methods described in clauses
(i) and (ii). 
 (d) For illustrative purposes, Exhibit C sets forth examples of the number of Warrant Shares
issuable upon a series of hypothetical exercises of the Warrants, in full and in part, under differing scenarios taking into consideration the change in the calculation of the Exercise Amount resulting from the date of exercise of the Warrants
taking place either prior to the IPO Date or on or after the IPO Date. 
 SECTION 4.03. Issuance of Warrant Shares. As
soon as practicable on or after a Date of Exercise of any Warrants, the Company shall issue, or cause the Transfer Agent to issue, a certificate or certificates for the number of full Warrant Shares equal to the Exercise Amount rounded down to the
nearest full share, registered in accordance with the instructions set forth in the Election to Purchase. All Warrant Shares issued upon the exercise of any Warrant in accordance with the Warrant Certificate and this Agreement shall be validly
authorized and issued, fully paid, nonassessable, free of preemptive rights and, subject to Section 6.01 hereof, free from all taxes, liens, charges and security interests in respect of the issuance thereof. Each Person in whose name any such
certificate for Warrant Shares is issued shall be deemed for all purposes to have become the holder of record of the Common Stock represented thereby on the Date of Exercise of the Warrant resulting in the issuance of such shares, irrespective of
the date of issuance or delivery of such certificate for Warrant Shares. 

  
 8 

 SECTION 4.04. Certificates for Unexercised Warrants. In the event that, prior to the
Expiration Date, a Warrant Certificate is exercised in respect of less than all of the Exercise Percentage specified therein, a new Warrant Certificate representing a Warrant for the remaining Exercise Percentage shall be issued and delivered
pursuant to the provisions hereof. 
 SECTION 4.05. Reservation of Shares. The Company shall at all times reserve and
keep available, solely for issuance and delivery upon exercise of the Warrants, the number of Warrant Shares from time to time issuable upon exercise of the Warrants. The transfer agent for the Common Stock, which may be the Company (the
“Transfer Agent”), and every subsequent Transfer Agent for any shares of the Company’s capital stock issuable upon the exercise of any of the purchase rights represented by the Warrants, are hereby irrevocably authorized and
directed at all times until the Expiration Date to reserve such number of authorized and unissued shares as shall be requisite for such purpose. The Company shall keep copies of each Warrant on file with the Transfer Agent for the Common Stock and
with every subsequent Transfer Agent for any shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrants. All Warrants surrendered upon the exercise of the rights thereby evidenced and
not required to be returned to the Holder pursuant hereto shall be canceled. 
 SECTION 4.06. No Impairment. The Company
shall not by any action, including, without limitation, amending its certificate of incorporation or through any 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 of the Warrants, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect
the rights of Holders against impairment. 
 SECTION 4.07. Expiration of Warrants. Each Warrant not exercised prior to
the Expiration Date shall become void and all rights thereunder and all rights in respect thereof under this Agreement shall cease as of such time. 
 ARTICLE V 
 ADJUSTMENTS AND NOTICE PROVISIONS 

SECTION 5.01. Adjustment of Exercise Price; Adjustment of Number of Shares. 

(a) In case the Company shall declare a dividend or make a distribution on the outstanding shares of its Common Stock (including any
distribution upon liquidation, dissolution or winding up), holders of Warrants shall be entitled to receive a pro rata portion of such dividend or distribution on an “as if” exercised basis upon the exercise of the Warrants. In case the
Company shall (i) subdivide or reclassify the outstanding shares of its Common Stock into a greater number of shares or (ii) combine or reclassify the outstanding shares of its Common Stock into a smaller number of shares, or any similar
event shall occur, the Exercise Price in effect immediately after the effective date of such subdivision, combination or reclassification shall be adjusted so that it shall equal the price determined by multiplying the Exercise Price in effect
immediately prior thereto by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding immediately before such subdivision, combination or reclassification, and of which the denominator shall be the number of
shares of Common Stock 

  
 9 

 
outstanding immediately after such subdivision, combination or reclassification. Such adjustment shall be made successively whenever any event specified above shall occur. 

(b) In connection with each adjustment of the Exercise Price pursuant to Section 5.01(a) hereof, but only if such adjustment occurs
after the IPO Date, each Warrant shall thereupon evidence the right to purchase that number of Warrant Shares obtained by multiplying the number of Warrant Shares purchasable immediately prior to such adjustment upon exercise of the Warrant by the
Exercise Price in effect immediately prior to such adjustment and dividing the product so obtained by the Exercise Price in effect immediately after such adjustment. 
 SECTION 5.02. Reorganizations. In case of any capital reorganization, other than in the cases referred to in Section 5.01 hereof, or the consolidation or merger of the Company with or into
another corporation (other than a merger or consolidation in which the Company is the continuing corporation and which does not result in any reclassification of the outstanding shares of Common Stock or the conversion of such outstanding shares of
Common Stock into shares of other stock or other securities or property) (collectively such actions being hereinafter referred to as “Reorganizations”), there shall thereafter be deliverable upon exercise of any Warrant (in lieu of
the number of Warrant Shares theretofore deliverable) the number of shares of stock or cash or other securities or property to which a Holder (of the number of Warrant Shares which would otherwise have been deliverable upon the exercise of such
Warrants) would have been entitled upon such Reorganization if such Warrant had been exercised in full immediately prior to such Reorganization. In case of any Reorganization, appropriate adjustment, as determined in good faith by the Board of
Directors, shall be made in the application of the provisions herein set forth with respect to the rights and interests of Holders so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any
shares or cash or other securities or property thereafter deliverable upon exercise of Warrants. Any such adjustment shall be made by and set forth in a supplemental agreement between the Company and any successor thereto. The Company shall not
effect any such Reorganization unless upon or prior to the consummation thereof the successor corporation, or if the Company shall be the surviving corporation in any such Reorganization and is not the issuer of the shares of stock or other
securities or property to be delivered to holders of shares of the Common Stock outstanding at the effective time thereof then such issuer, shall assume by written instrument the obligation to deliver to the Holder of any Warrant Certificate such
shares or cash or other securities or property as such Holder shall be entitled to purchase in accordance with the foregoing provisions. 
 SECTION 5.03. Notice of Certain Actions. In the event the Company shall (a) declare any dividend payable in stock to the holders of its Common Stock or make any other distribution in property
other than cash to the holders of its Common Stock, (b) offer to all holders of its Common Stock rights to subscribe for or purchase any shares of any class of stock or any other rights or options, (c) effect or approve or enter into any
arrangements to effect an Initial Public Offering, (d) effect any reclassification of its Common Stock (other than a reclassification involving merely the subdivision or combination of outstanding shares of Common Stock), (e) effect or
approve any capital reorganization or any consolidation or merger (other than a merger in which no distribution of cash, securities or other property is made to holders of Common Stock), (f) effect or approve any Substantial Disposition
Transaction, or (g) effect or approve the liquidation, dissolution or winding up of the Company; then, in each such 

  
 10 

 
case, the Company shall cause notice of such proposed action to be mailed to each Holder in the manner set forth below. Such notice shall specify the date on which the books of the Company shall
close, or a record be taken, for determining holders of Common Stock entitled to receive such stock dividend or other distribution or such rights or options, or the date on which such reclassification, reorganization, consolidation, merger, sale,
transfer, other disposition, liquidation, dissolution, winding up or exchange shall take place or commence, as the case may be, and the date as of which it is expected that holders of record of Common Stock shall be entitled to receive cash,
securities or other property deliverable upon such action, if any such date has been fixed. Such notice shall be mailed in the case of any action covered by clause (a) or (b) of this Section 5.03 at least ten (10) days prior to
the record date for determining holders of the Common Stock for purposes of receiving such payment or offer; in the case of any action covered by clause (c) above, within ten (10) days of the action giving rise to the obligation to mail
such notice; and in the case of any action covered by clause (d), (e), (f) or (g) above, at least 10 days prior to the earlier of the date upon which such action is to take place or any record date to determine holders of Common Stock
entitled to receive such cash, securities or other property. 
 SECTION 5.04. Certificate of Adjustments. Whenever any
adjustment is to be made pursuant to this Article V, the Company shall prepare a certificate executed by an Officer of the Company setting forth such adjustments to be mailed to each Holder, such notice to include in reasonable detail: (a) the
events in respect of which the adjustment is being made, (b) the computation of any adjustments, and (c) the Exercise Price and the number of shares or the cash or other securities or property purchasable upon exercise of each Warrant
after giving effect to such adjustment. Such notice shall be given promptly after the events in respect of which the adjustment is being made have occurred. 
 SECTION 5.05. Warrant Certificate Amendments. Irrespective of any adjustments pursuant to this Article V, Warrant Certificates theretofore or thereafter issued need not be amended or replaced, but
certificates thereafter issued shall bear an appropriate legend or other notice of any adjustments; provided, however, that the Company may, at its option, issue new Warrant Certificates evidencing Warrants in such form as may be
approved by the Board of Directors to reflect any adjustment in the Exercise Price and number of Warrant Shares purchasable under the Warrants. 
 SECTION 5.06. Fractional Shares. No fractional shares of Common Stock will be issued in connection with any exercise hereunder. In lieu of any remaining fractional share that may exist after
aggregating all fractional shares for any Holder, the Company may pay an amount of cash to such Holder equal to the fraction multiplied by the Fair Market Value of a share of Common Stock.

 INVESTMENT REPRESENTATION STATEMENT 
  

					
		  		  	 Shares of Common Stock
 of
Syndax Pharmaceuticals, Inc.

 In connection with the purchase of the above-listed securities the undersigned hereby represents to Syndax
Pharmaceuticals, Inc. (the “Company”) as follows: 
 1. Receipt of Information. The undersigned has received all
the information it considers necessary or appropriate for deciding whether to purchase the Common Stock issuable upon exercise of the Warrant (the “Warrant”) issued by the Company to the undersigned. 

2. Investment Representation. 
 (a) The shares of stock to be received upon the exercise of the Warrant (the “Securities”) will be acquired for investment for its own account, not as a nominee or agent, and not with a view to
the sale or distribution of any part thereof, and the undersigned has no present intention of selling, granting participation in or otherwise distributing the same, but subject, nevertheless, to any requirement of law that the disposition of its
property shall at all times be within its control. 
 (b) The undersigned understands that the Securities issuable upon exercise
of the Warrant at the time of issuance may not be registered under the Securities Act of 1933, as amended (the “Act”), and applicable state securities laws, on the ground that the issuance of such securities is exempt pursuant to
Section 4(2) of the Act and state law exemptions relating to offers and sales not by means of a public offering, and that the Company’s reliance on such exemptions is predicated in part on the undersigned’s representations set forth
herein. 
 (c) The undersigned agrees that in no event will it make a disposition of any Securities acquired upon the exercise
of the Warrant (other than pursuant to Rule 144 or Rule 144A promulgated by the Securities and Exchange Commission under the Act or any similar or analogous rule) unless and until (x) for dispositions made to a Person other than an Affiliate of
the Holder, (i) it shall have notified the Company of the proposed disposition and (if requested by the Company) shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition, and (ii) it shall
have furnished the Company with an opinion of counsel satisfactory to the company and the Company’s counsel to the effect that (A) appropriate action necessary for compliance with the Act and any applicable state securities laws has been
taken or an exemption from the registration requirements of the Act and such laws is available, and (B) that the proposed transfer will not violate any of said laws and (y) for dispositions made to an Affiliate of the Holder, it shall have
notified the Company of the disposition within 10 Business Days after the disposition. For purposes of Section 2(c), Affiliate shall not include any Person which is an individual. 

  
 B-1

 (d) The undersigned represents that it has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of its investments. 
 (e) The undersigned acknowledges
that the Securities issuable upon exercise of the Warrant must be held indefinitely unless subsequently registered under the Act or an exemption from such registration is available. The undersigned is aware of the provisions of Rule 144 promulgated
under the Act which permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions. The undersigned is aware that the conditions for resale set forth in Rule 144 may not have been satisfied.

 Exhibit C 
 EXAMPLES OF CALCULATION OF WARRANT SHARES BEING EXERCISED ON A 
 GIVEN EXERCISE DATE
AND WARRANT SHARES REMAINING THEREAFTER 
 Example A: 
 Assuming that: 
  

	(1)	the number of shares of Common Stock outstanding on a fully diluted basis, not including the Warrant Shares, as of 15-Jan-07 = 100,000,000

  

	(2)	an IPO has not been consummated as of 15-Dec-07; and 

  

	(3)	Bayer determines to exercise the Warrants in full on January 15, 2007. 

 Then: 
 Exercise Amount = 

(1.75% * E * N) 

Divided by 

[1-1.75%*(A+R)] 
 Where:

  

	E =	Exercise Percentage being exercised by Holder 

  

	N =	Number of shares of Common Stock outstanding on a Fully Diluted Basis before exercise of the Warrant, not including outstanding Warrants issued hereunder

  

	A =	Aggregate Exercise Percentage held by exercising Holder before exercise of the Warrant 

 

	R =	Remaining Exercise Percentage held by all other Holders (not including the exercising Holder) 

 

	* =	Multiplied by 

 where 

 

	(i)	E = 100% 

  

	(ii)	N = 100,000,000 

  

	(iii)	A = 100% 

  

	(iv)	R = 0% 

 Exercise Amount calculated as follows:

 [(0.0175*1.00*100,000,000)/(1-0.0175*(1.00+0))] = 1,781,170.48 
 Accordingly Bayer would be issued 1,781,170 shares of Common Stock, the number of shares of Common Stock outstanding on a Fully Diluted Basis following the exercise of the Warrant would be equal to
101,781,170 there would be no remaining unexercised portion of the Grant Percentage and no remaining Warrant Shares issuable. 

  
 C-1

 Example B: 
 Assuming that: 
  

	(1)	the number of shares of Common Stock outstanding on a fully diluted basis, not including the Warrant Shares, as of: 

15-Jan-07 = 100,000,000 
 15-Mar-07 = 110,000,000 
 15-Aug-07 = 120,000,000 

15-Dec-07 = 130,000,000; 
  

	(2)	an IPO has not been consummated as of 15-Dec-07; and 

  

	(3)	Bayer determines to exercise the Warrants as to an Exercise Percentage of 25% on each of the following dates: 

15-Jan-07 

15-Mar-07 

15-Aug-07 

15-Dec-07; 
 Then: 

Exercise Amount = 

(1.75% * E * N) 

Divided by 

[1-1.75%*(A+R)] 
 Where:

  

	E =	Exercise Percentage being exercised by Holder 

  

	N =	Number of shares of Common Stock outstanding on a Fully Diluted Basis before exercise of the Warrant, not including outstanding Warrants issued hereunder

  

	A =	Aggregate Exercise Percentage held by exercising Holder before exercise of the Warrant 

 

	R =	Remaining Exercise Percentage held by all other Holders (not including the exercising Holder) 

 

	* =	Multiplied by 

 on 15-Jan-07, where 

 

	(i)	E = 25% 

  

	(ii)	N = 100,000,000 

  

	(iii)	A = 100% 

  

	(iv)	R = 0% 

 Exercise Amount calculated as follows:

 [(0.0175*.25*100,000,000)/(1-0.0175*(1.00+0))] = 445,292.61 
 Accordingly Bayer would be issued 445,292 shares of Common Stock as of 15-Jan-07, the remaining aggregate exercise percentage held by all Holders would equal 75% and Warrant Shares remain issuable.

  
 C-2

 on 15-Mar-07 
  

	(i)	E = 25% 

  

	(ii)	N = 110,000,000 

  

	(iii)	A = 75% 

  

	(iv)	R = 0% 

 Exercise Amount calculated as follows:

 [(0.0175*.25*110,000,000)/(1-0.0175*(.75+0))] = 487,650.41 
 Accordingly Bayer would be issued 487,650 shares of Common Stock as of 15-Mar-07, the remaining aggregate exercise percentage held by all Holders would equal 50% and Warrant Shares remain issuable.

The Plan may be administered by different administrative bodies with respect to different classes of Participants and, if permitted by the Applicable Laws, the Board may authorize one or more officers to make awards under the Plan.

serve in its designated capacity until otherwise directed by the Board. From time to time the Board may increase the size of any Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies (however caused) and remove all members of a Committee and thereafter directly administer the Plan, all to the extent permitted by the 

  
 4 

 
Applicable Laws and, in the case of a Committee administering the Plan in accordance with the requirements of Rule 16b-3 or Section 162(m) of the Code, to the extent permitted or required by
such provisions. The Committee shall in all events conform to any requirements of the Applicable Laws. 
 (c) Powers of the
Administrator. Subject to the provisions of the Plan and in the case of a Committee, the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: 

(i) to determine the Fair Market Value of the Common Stock, in accordance with Section 2(p) of the Plan, provided that such
determination shall be applied consistently with respect to Participants under the Plan; 
 (ii) to select the Employees and Consultants to
whom Plan awards may from time to time be granted; 
 (iii) to determine whether and to what extent Plan awards are granted; 

(iv) to determine the number of Shares of Common Stock to be covered by each award granted; 

(v) to approve the form(s) of agreement(s) used under the Plan; 

(vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder, which terms and
conditions include but are not limited to the exercise or purchase price, the time or times when awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, any pro rata
adjustment to vesting as a result of a Participant’s transitioning from full- to part-time service (or vice versa), and any restriction or limitation regarding any Option, Optioned Stock, Stock Purchase Right or Restricted Stock, based in each
case on such factors as the Administrator, in its sole discretion, shall determine; 
 (vii) to determine whether and under what
circumstances an Option may be settled in cash under Section 10(c) instead of Common Stock; 
 (viii) to implement an Option Exchange
Program on such terms and conditions as the Administrator in its discretion deems appropriate, provided that no amendment or adjustment to an Option that would materially and adversely affect the rights of any Optionee shall be made without the
prior written consent of the Optionee; 
 (ix) to adjust the vesting of an Option held by an Employee or Consultant as a result of a change
in the terms or conditions under which such person is providing services to the Company; 
 (x) to construe and interpret the terms of the
Plan and awards granted under the Plan, which constructions, interpretations and decisions shall be final and binding on all Participants; and 

  
 5 

 (xi) in order to fulfill the purposes of the Plan and without amending the Plan, to modify
grants of Options or Stock Purchase Rights to Participants who are foreign nationals or employed outside of the United States in order to recognize differences in local law, tax policies or customs. 

5. Eligibility. 

(a) Recipients of Grants. Nonstatutory Stock Options and Stock Purchase Rights may be granted to Employees and Consultants.
Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible to receive Incentive Stock Options. 

(b) Type of Option. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. 
 (c) ISO $100,000 Limitation. Notwithstanding any designation under Section 5(b), to the
extent that the aggregate Fair Market Value of Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair
Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 
 (d)
No Employment Rights. The Plan shall not confer upon any Participant any right with respect to continuation of an employment or consulting relationship with the Company, nor shall it interfere in any way with such Participant’s
right or the Company’s right to terminate the employment or consulting relationship at any time for any reason. 
 6. Term of
Plan. The Plan shall become effective upon its adoption by the Board of Directors. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 16 of the Plan. 

7. Term of Option. The term of each Option shall be the term stated in the Option Agreement; provided that the term shall be no
more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and provided further that, in the case of an Incentive Stock Option granted to a person who at the time of such grant is a
Ten Percent Holder, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 

8. [Reserved.] 
 9.
Option Exercise Price and Consideration. 
 (a) Exercise Price. The per Share exercise price for the
Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator and set forth in the Option Agreement, but shall be subject to the following: 

  
 6 

 (i) In the case of an Incentive Stock Option 

(A) granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than one hundred
ten percent (110%) of the Fair Market Value per Share on the date of grant; or 
 (B) granted to any other Employee, the per Share
exercise price shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (ii) In
the case of a Nonstatutory Stock Option 
 (A) granted on any date on which the Common Stock is not a Listed Security to a person who at
the time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required,
shall be such price as is determined by the Administrator; 
 (B) granted on any date on which the Common Stock is not a Listed Security to
any other eligible person, the per Share exercise price shall be no less than eighty-five percent (85%) of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as
is determined by the Administrator; or 
 (C) granted on any date on which the Common Stock is a Listed Security to any eligible person,
the per share Exercise Price shall be such price as determined by the Administrator provided that if such eligible person is, at the time of the grant of such Option, a Named Executive of the Company, the per share Exercise Price shall be no less
than one hundred percent (100%) of the Fair Market Value on the date of grant if such Option is intended to qualify as performance-based compensation under Section 162(m) of the Code. 

(iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as required above pursuant to a merger
or other Corporate Transaction. 
 (b) Permissible Consideration. The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist entirely of (1) cash;
(2) check; (3) subject to any requirements of the Applicable Laws (including without limitation Section 153 of the Delaware General Corporation Law), delivery of Optionee’s promissory note having such recourse, interest, security
and redemption provisions as the Administrator determines to be appropriate after taking into account the potential accounting consequences of permitting an Optionee to deliver a promissory note; (4) cancellation of indebtedness; (5) other
Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option is exercised, provided that in the case of Shares acquired, directly or indirectly, from the Company, such
Shares must have been owned by the Optionee for more than six (6) months on the date of surrender (or such other period as may be required to avoid the Company’s incurring an adverse 

  
 7 

 
accounting charge); (6) if, as of the date of exercise of an Option the Company then is permitting employees to engage in a “same-day sale” cashless brokered exercise program
involving one or more brokers, through such a program that complies with the Applicable Laws (including without limitation the requirements of Regulation T and other applicable regulations promulgated by the Federal Reserve Board) and that ensures
prompt delivery to the Company of the amount required to pay the exercise price and any applicable withholding taxes; or (7) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to
accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Administrator may, in its sole discretion, refuse to accept a particular form of consideration at the time of any
Option exercise. 
 10. Exercise of Option. 

(a) General. 
 (i)
Exercisability. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, consistent with the term of the Plan and reflected in the Option Agreement, including vesting
requirements and/or performance criteria with respect to the Company and/or the Optionee; provided however that, if required under the Applicable Laws, the Option (or Shares issued upon exercise of the Option) shall comply with the requirements of
Section 260.140.41(f) and (k) of the Rules of the California Corporations Commissioner. 
 (ii) Leave of Absence.
The Administrator shall have the discretion to determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be
tolled during any such unpaid leave (unless otherwise required by the Applicable Laws). In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from military
leave (under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have
applied had the Participant continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 

(iii) Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Administrator may require
that an Option be exercised as to a minimum number of Shares, provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 

(iv) Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice of such exercise has been
given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the Option is exercised. Full payment may, as authorized by
the Administrator, consist of any consideration and method of payment allowable under Section 9(b) of the Plan, provided that the Administrator may, in its sole discretion, refuse to accept any form of consideration at the time of any Option
exercise. 

  
 8 

 Exercise of an Option in any manner shall result in a decrease in the number of Shares that thereafter may be
available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (v)
Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other
rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 14 of the Plan. 
 (b) Termination of Employment or Consulting Relationship. Except
as otherwise set forth in this Section 10(b), the Administrator shall establish and set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an
Optionee’s Continuous Service Status, which provisions may be waived or modified by the Administrator at any time. Unless the Administrator otherwise provides in the Option Agreement, to the extent that the Optionee is not vested in Optioned
Stock at the date of termination of his or her Continuous Service Status, or if the Optionee (or other person entitled to exercise the Option) does not exercise the Option to the extent so entitled within the time specified in the Option Agreement
or below (as applicable), the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option shall revert to the Plan. In no event may any Option be exercised after the expiration of the Option term as set forth in
the Option Agreement (and subject to Section 7). 
 The following provisions (1) shall apply to the extent an Option Agreement
does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s Continuous Service Status, and (2) establish the minimum post-termination exercise periods that may be set forth in an Option
Agreement: 
 (i) Termination other than Upon Disability or Death. In the event of termination of Optionee’s Continuous
Service Status other than under the circumstances set forth in subsections (ii) and (iii) below, such Optionee may exercise an Option for thirty (30) days following such termination to the extent the Optionee was vested in the
Optioned Stock as of the date of such termination. No termination shall be deemed to occur and this Section 10(b)(i) shall not apply if (i) the Optionee is a Consultant who becomes an Employee, or (ii) the Optionee is an Employee who
becomes a Consultant. 
 (ii) Disability of Optionee. In the event of termination of an Optionee’s Continuous Service
Status as a result of his or her disability (including a disability within the meaning of Section 22(e)(3) of the Code), such Optionee may exercise an Option at any time within six (6) months following such termination to the extent the
Optionee was vested in the Optioned Stock as of the date of such termination. 
 (iii) Death of Optionee. In the event of the
death of an Optionee during the period of Continuous Service Status since the date of grant of the Option, or within thirty (30) days following termination of Optionee’s Continuous Service Status, the Option may be exercised by
Optionee’s estate or by a person who acquired the right to exercise the Option by 

  
 9 

 
bequest or inheritance at any time within twelve (12) months following the date of death, but only to the extent the Optionee was vested in the Optioned Stock as of the date of death or, if
earlier, the date the Optionee’s Continuous Service Status terminated. 
 (c) Buyout Provisions. The Administrator may
at any time offer to buy out for a payment in cash or Shares an Option previously granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

 11. Stock Purchase Rights. 

(a) Rights to Purchase. When the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such
offer. In the case of a Stock Purchase Right granted prior to the date, if any, on which the Common Stock becomes a Listed Security and if required by the Applicable Laws at that time, the purchase price of Shares subject to such Stock Purchase
Rights shall not be less than eighty-five percent (85%) of the Fair Market Value of the Shares as of the date of the offer, or, in the case of a Ten Percent Holder, the price shall not be less than one hundred percent (100%) of the Fair
Market Value of the Shares as of the date of the offer. If the Applicable Laws do not impose the requirements set forth in the preceding sentence and with respect to any Stock Purchase Rights granted after the date, if any, on which the Common Stock
becomes a Listed Security, the purchase price of Shares subject to Stock Purchase Rights shall be as determined by the Administrator. The offer to purchase Shares subject to Stock Purchase Rights shall be accepted by execution of a Restricted Stock
Purchase Agreement in the form determined by the Administrator. 
 (b) Repurchase Option. 

(i) General. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s Continuous Service Status with the Company for any reason (including death or disability). Subject to any requirements of the Applicable Laws
(including without limitation Section 260.140.42(h) of the Rules of the California Corporations Commissioner), the terms of the Company’s repurchase option (including without limitation the price at which, and the consideration for which,
it may be exercised, and the events upon which it shall lapse) shall be as determined by the Administrator in its sole discretion and reflected in the Restricted Stock Purchase Agreement. 

(ii) Leave of Absence. The Administrator shall have the discretion to determine whether and to what extent the lapsing of
Company repurchase rights shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, such lapsing shall be tolled during any such unpaid leave (unless otherwise required by the Applicable Laws).
In the event of military leave, the lapsing of Company repurchase rights shall toll during any unpaid portion of such leave, provided that, upon a Participant’s returning from military leave (under conditions that would entitle him or her to

  
 10 

 
protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given “vesting” credit with respect to Shares purchased pursuant to
the Restricted Stock Purchase Agreement to the same extent as would have applied had the Participant continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such
leave. 
 (c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and
conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock Purchase Agreements need not be the same with respect to each purchaser. 

(d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to those
of a stockholder, and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 14 of the Plan. 
 12. Taxes. 

(a) As a condition of the grant, vesting or exercise of an Option or Stock Purchase Right granted under the Plan, the Participant (or in the
case of the Participant’s death, the person exercising the Option or Stock Purchase Right) shall make such arrangements as the Administrator may require for the satisfaction of any applicable federal, state, local or foreign withholding tax
obligations that may arise in connection with such grant, vesting or exercise of the Option or Stock Purchase Right or the issuance of Shares. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied.
If the Administrator allows the withholding or surrender of Shares to satisfy a Participant’s tax withholding obligations under this Section 12 (whether pursuant to Section 12(c), (d) or (e), or otherwise), the Administrator
shall not allow Shares to be withheld in an amount that exceeds the minimum statutory withholding rates for federal and state tax purposes, including payroll taxes. 

(b) In the case of an Employee and in the absence of any other arrangement, the Employee shall be deemed to have directed the Company to
withhold or collect from his or her compensation an amount sufficient to satisfy such tax obligations from the next payroll payment otherwise payable after the date of an exercise of the Option or Stock Purchase Right. 

(c) This Section 12(c) shall apply only after the date, if any, upon which the Common Stock becomes a Listed Security. In the case of a
Participant other than an Employee (or in the case of an Employee where the next payroll payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in the absence of any other arrangement and to the
extent permitted under the Applicable Laws, the Participant shall be deemed to have elected to have the Company withhold from the Shares to be issued upon exercise of the Option or Stock Purchase Right that number of Shares having a Fair Market
Value determined as of the applicable Tax Date (as defined below) equal to the amount required to be withheld. For purposes of this Section 12, the Fair Market Value of the Shares to be 

  
 11 

 
withheld shall be determined on the date that the amount of tax to be withheld is to be determined under the Applicable Laws (the “Tax Date”). 

(d) If permitted by the Administrator, in its discretion, a Participant may satisfy his or her tax withholding obligations upon exercise of an
Option or Stock Purchase Right by surrendering to the Company Shares that have a Fair Market Value determined as of the applicable Tax Date equal to the amount required to be withheld. In the case of shares previously acquired from the Company that
are surrendered under this Section 12(d), such Shares must have been owned by the Participant for more than six (6) months on the date of surrender (or such other period of time as is required for the Company to avoid adverse accounting
charges). 
 (e) Any election or deemed election by a Participant to have Shares withheld to satisfy tax withholding obligations under
Section 12(c) or (d) above shall be irrevocable as to the particular Shares as to which the election is made and shall be subject to the consent or disapproval of the Administrator. Any election by a Participant under Section 12(d)
above must be made on or prior to the applicable Tax Date. 
 (f) In the event an election to have Shares withheld is made by a Participant
and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Participant shall receive the full number of Shares with respect to which the Option or Stock Purchase Right is
exercised but such Participant shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 

13. Non-Transferability of Options and Stock Purchase Rights. 

(a) General. Except as set forth in this Section 13, Options and Stock Purchase Rights may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option or Stock Purchase Right may be exercised,
during the lifetime of the holder of an Option or Stock Purchase Right, only by such holder or a transferee permitted by this Section 13. 

(b) Limited Transferability Rights. Notwithstanding anything else in this Section 13, the Administrator may in its
discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the Options are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift or pursuant to
domestic relations orders to “Immediate Family Members” (as defined below) of the Optionee. “Immediate Family Member” means any 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), a trust in which these persons have more than fifty percent (50%) of the beneficial interest, a
foundation in which these persons (or the Optionee) control the management of assets, and any other entity in which these persons (or the Optionee) own more than fifty percent (50%) of the voting interests.

 14. Adjustments Upon Changes in Capitalization, Merger or Certain Other
Transactions. 
 (a) Changes in Capitalization. Subject to any action required under Applicable Laws by the
stockholders of the Company, the number of Shares of Common Stock covered by each outstanding award and the number of Shares of Common Stock that have been authorized for issuance under the Plan but as to which no awards have yet been granted or
that have been returned to the Plan upon cancellation or expiration of an award, as well as the price per Share of Common Stock covered by each such outstanding award, shall be proportionately adjusted for any increase or decrease in the number of
issued Shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination, recapitalization or reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares of Common Stock
effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall
be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares of Common Stock subject to an award. 

(b) Dissolution or Liquidation. In the event of the dissolution or liquidation of the Company, each Option and Stock Purchase
Right will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 
 (c)
Corporate Transaction. In the event of a Corporate Transaction (including without limitation a Change of Control), each outstanding Option or Stock Purchase Right shall be assumed or an equivalent option or right shall be substituted
by such successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), unless the Successor Corporation does not agree to assume the award or to substitute an equivalent option or right,
in which case such Option or Stock Purchase Right shall terminate upon the consummation of the transaction. 
 For purposes of this
Section 14(c), an Option or a Stock Purchase Right shall be considered assumed, without limitation, if, at the time of issuance of the stock or other consideration upon a Corporate Transaction or a Change of Control, as the case may be, each
holder of an Option or Stock Purchase Right would be entitled to receive upon exercise of the award the same number and kind of shares of stock or the same amount of property, cash or securities as such holder would have been entitled to receive
upon the occurrence of the transaction if the holder had been, immediately prior to such transaction, the holder of the number of Shares of Common Stock covered by the award at such time (after giving effect to any adjustments in the number of
Shares covered by the Option or Stock Purchase Right as provided for in this Section 14); provided that if such consideration received in the transaction is not solely common stock of the Successor Corporation, the Administrator may, with the
consent of the Successor Corporation, provide for the consideration to be received upon exercise of the award to be solely common stock of the Successor Corporation equal to the Fair Market Value of the per Share consideration received by holders of
Common Stock in the transaction. 

  
 13 

 (d) Certain Distributions. In the event of any distribution to the Company’s
stockholders of securities of any other entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, appropriately adjust the price
per Share of Common Stock covered by each outstanding Option or Stock Purchase Right to reflect the effect of such distribution. 
 15.
Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase
Right, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be the later of the date on which the Administrator makes the determination granting such Incentive Stock
Option or the date of commencement of the Optionee’s employment relationship with the Company. Notice of the determination shall be given to each Employee or Consultant to whom an Option or Stock Purchase Right is so granted within a reasonable
time after the date of such grant. 
 16. Amendment and Termination of the Plan. 

(a) Authority to Amend or Terminate. The Board may at any time amend, alter, suspend or discontinue the Plan, but no amendment,
alteration, suspension or discontinuation (other than an adjustment pursuant to Section 14 above) shall be made that would materially and adversely affect the rights of any Optionee or holder of Stock Purchase Rights under any outstanding
grant, without his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required. 

(b) Effect of Amendment or Termination. Except as to amendments which the Administrator has the authority under the Plan to make
unilaterally, no amendment or termination of the Plan shall materially and adversely affect Options or Stock Purchase Rights already granted, unless mutually agreed otherwise between the Optionee or holder of the Stock Purchase Rights and the
Administrator, which agreement must be in writing and signed by the Optionee or holder and the Company. 
 17. Conditions Upon
Issuance of Shares. Notwithstanding any other provision of the Plan or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any
Shares under the Plan unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. As a condition to the exercise of an Option or Stock Purchase Right,
the Company may require the person exercising the award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by law. Shares issued upon exercise of awards granted prior to the date on which the Common Stock becomes a Listed Security shall be subject to a right of first refusal in favor
of the Company pursuant to which the Participant will be required to offer Shares to the Company before selling or transferring them to any third party on such terms and subject to such conditions as is reflected in the applicable Option Agreement
or Restricted Stock Purchase Agreement. 

  
 14 

 18. Reservation of Shares. The Company, during the term of this Plan, will at all
times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
 19.
Agreements. Options and Stock Purchase Rights shall be evidenced by Option Agreements and Restricted Stock Purchase Agreements, respectively, in such form(s) as the Administrator shall from time to time approve. 

20. Stockholder Approval. If required by the Applicable Laws, continuance of the Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months before or after the date the Plan is adopted. Such stockholder approval shall be obtained in the manner and to the degree required under the Applicable Laws. 

21. Information and Documents to Optionees and Purchasers. Prior to the date, if any, upon which the Common Stock becomes a
Listed Security and if required by the Applicable Laws, the Company shall provide financial statements at least annually to each Optionee and to each individual who acquired Shares pursuant to the Plan, during the period such Optionee or purchaser
has one or more Options or Stock Purchase Rights outstanding, and in the case of an individual who acquired Shares pursuant to the Plan, during the period such individual owns such Shares. The Company shall not be required to provide such
information if the issuance of Options or Stock Purchase Rights under the Plan is limited to key employees whose duties in connection with the Company assure their access to equivalent information.
