Bank, the Lenders from time to time party thereto, and the Company (the “Loan Agreement”).

 THIS WARRANT CERTIFIES THAT, for good and valuable consideration, SILICON VALLEY BANK (together with any
successor or permitted assignee or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) has delivered to the above-named company (the “Company”) a duly executed signature
page to the Stockholder Option and Support Agreement with Genentech, Inc., a Delaware corporation, in the form attached hereto as Appendix 1 (an “Option and Support Agreement”), and is entitled to purchase the above-stated
number of fully paid and non-assessable shares (the “Shares”) of the above-stated Type/Series of Stock (the “Class”) of the Company at the above-stated Warrant
Price, all as set forth above and as adjusted pursuant to Section 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. Reference is made to Section 5.4 of this Warrant whereby Silicon
Valley Bank shall transfer this Warrant to its parent company, SVB Financial Group, subject to the conditions stated therein. FOR CLARIFICATION, THE COMPANY AGREES THAT THE OPTION AND SUPPORT AGREEMENT IS BEING SIGNED BY HOLDER SOLELY IN ITS
CAPACITY AS A HOLDER OF EQUITY SECURITIES OF THE COMPANY AND NOT AS A LENDER OR COLLATERAL AGENT. THE 

  
 1 








 
COMPANY AGREES THAT SUCH OPTION AND SUPPORT AGREEMENT SHALL NOT BIND HOLDER OR ANY OF ITS AFFILIATES IN HOLDER’S OR SUCH AFFILIATE’S CAPACITY AS A LENDER OR COLLATERAL AGENT IN ANY WAY,
NOR SHALL IT AFFECT OR IN ANY WAY IMPAIR ANY RIGHTS OR REMEDIES THAT HOLDER OR ITS AFFILIATE MAY HAVE WITH RESPECT TO HOLDER’S OR SUCH AFFILIATE’S LOAN FACILITY WITH THE COMPANY. The two preceding sentences are not intended to impair
Genentech, Inc.’s rights with respect to the equity securities as covered by the Option and Support Agreement. 
 SECTION 1.
EXERCISE. 
 1.1 Method of Exercise. Holder may at any time and from time to time exercise this Warrant, in whole or in part,
by delivering to the Company the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 2 and, unless Holder is exercising this Warrant pursuant to a cashless exercise set
forth in Section 1.2, a check, wire transfer of same-day funds (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares
being purchased. 
 1.2 Cashless Exercise. On any exercise of this Warrant, in lieu of payment of the aggregate Warrant Price in the
manner as specified in Section 1.1 above, but otherwise in accordance with the requirements of Section 1.1, Holder may elect to receive Shares equal to the value of this Warrant, or portion hereof as to which this Warrant is being
exercised. Thereupon, the Company shall issue to the Holder such number of fully paid and non-assessable Shares as are computed using the following formula: 

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 (inclusive of the Shares surrendered to the Company in payment of the aggregate Warrant Price); 


 

	 	A =	the Fair Market Value (as determined pursuant to Section 1.3 below) of one Share; and 

  

	 	B =	the Warrant Price. 

 1.3 Fair Market Value. If the Company’s common stock is then
traded or quoted on a nationally recognized securities exchange, inter-dealer quotation system or over-the-counter market (a “Trading Market”)
and the Class is common stock, the fair market value of a Share shall be the closing price or last sale price of a share of common stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together
with its Notice of Exercise to the Company. If the Company’s common stock is then traded in a Trading Market and the Class is a series of the Company’s convertible preferred stock, the fair market value of a Share shall be the closing
price or last sale price of a share of the Company’s common stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together with its Notice of Exercise to the Company multiplied by the number of
shares of the Company’s common stock into which a Share is then convertible. If the Company’s common stock is not traded in a Trading Market, the Board of Directors of the Company shall determine the fair market value of a Share in its
reasonable good faith judgment. 

  
 2 








 1.4 Delivery of Certificate and New Warrant. Within a reasonable time after Holder
exercises this Warrant in the manner set forth in Section 1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise and, if this Warrant has not been fully exercised and has
not expired, a new warrant of like tenor representing the Shares not so acquired (or surrendered pursuant to Section 1.2 to the extent applicable). 

1.5 Replacement of Warrant. 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, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the
Company for cancellation, the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant of like tenor and amount. 

1.6 Treatment of Warrant Upon Acquisition of Company. 

(a) Acquisition. For the purpose of this Warrant, “Acquisition” means any transaction or series of
related transactions involving: (i) the sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the Company (ii) any merger or consolidation of the Company into or with another person or entity
(other than a merger or consolidation effected exclusively to change the Company’s domicile), or any other corporate reorganization, in which the stockholders of the Company in their capacity as such immediately prior to such merger,
consolidation or reorganization, own less than a majority of the Company’s (or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization; or (iii) any sale or other
transfer by the stockholders of the Company of shares representing at least a majority of the Company’s then-total outstanding combined voting power. 

(b) Treatment of Warrant at Acquisition. In the event of an Acquisition in which the consideration to be received by the Company’s
stockholders consists solely of cash, solely of Marketable Securities or a combination of cash and Marketable Securities (a “Cash/Public Acquisition”), either (i) Holder shall exercise this Warrant pursuant
to Section 1.1 and/or 1.2 and such exercise will be deemed effective immediately prior to and contingent upon the consummation of such Acquisition or (ii) if Holder elects not to exercise the Warrant, this Warrant will expire immediately
prior to the consummation of such Acquisition. 
 (c) The Company shall provide Holder with written notice of a contemplated Cash/Public
Acquisition (together with such reasonable information as Holder may reasonably require regarding the treatment of this Warrant in connection with such contemplated Cash/Public Acquisition giving rise to such notice), which is to be delivered to
Holder not less than seven (7) Business Days prior to the closing of the proposed Cash/Public Acquisition. In the event the Company does not provide such notice, then if, immediately prior to the Cash/Public Acquisition, the fair market value
of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above would be greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of
such date to be exercised pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised, and the Company shall promptly notify the Holder of the number of Shares (or such other
securities) issued upon such exercise to the Holder and Holder shall be deemed to have restated each of the representations and warranties in Section 4 of the Warrant as the date thereof. 

  
 3 








 (d) Upon the closing of any Acquisition other than a Cash/Public Acquisition defined above, the
acquiring, surviving or successor entity shall assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares issuable upon exercise of
the unexercised portion of this Warrant as if such Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this Warrant. 

(e) As used in this Warrant, “Marketable Securities” means securities meeting all of the following requirements:
(i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then current in its filing of
all required reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the Acquisition were Holder to exercise this
Warrant on or prior to the closing thereof is then traded in a Trading Market, and (iii) following the closing of such Acquisition, Holder would not be restricted from publicly re-selling all of the
issuer’s shares and/or other securities that would be received by Holder in such Acquisition were Holder to exercise or convert this Warrant in full on or prior to the closing of such Acquisition, except to the extent that any such restriction
(x) arises solely under federal or state securities laws, rules or regulations, and (y) does not extend beyond six (6) months from the closing of such Acquisition. 

(f) Notwithstanding anything to the contrary contained in this Warrant, in the event the Genentech Acquisition (as defined in the Loan
Agreement) is consummated as a merger pursuant to the Agreement and Plan of Merger dated January 9, 2012 among the Company, Genentech, Inc. and the other parties thereto (the “Merger Agreement”), this Warrant shall be treated in
accordance with the terms of Section 8.8(c) of the Merger Agreement. 
 1.7 Additional Shares. Upon the funding of each Term B
Loan (as defined in the Loan Agreement), the Company shall be deemed to have automatically granted to Holder, in addition to the number of Shares which this Warrant can otherwise be exercised for by Holder, the right to purchase that number of
additional Shares, rounded upward to the nearest whole number, equal to three percent (3.00%) of the amount of such Term B Loan funded by Silicon Valley Bank divided by the Warrant Price (such additional shares being called the
“Additional Shares”). 
 SECTION 2. ADJUSTMENTS TO THE SHARES AND WARRANT PRICE. 

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding shares of the
Class payable in common stock or other securities or property (other than cash), then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and
property which Holder would have received had Holder owned the Shares of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of the Class by reclassification or otherwise into a greater
number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares of the Class are combined or consolidated, by reclassification
or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased. 

2.2 Reclassification, Exchange, Combinations or Substitution. Upon any event whereby all of the outstanding shares of the Class are
reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such event, this Warrant will be exercisable for the number, class and
series of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further adjustment thereafter from time to time in accordance with the provisions of this
Warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events. 

  
 4 








 2.3 Conversion of Preferred Stock. If the Class is a class and series of the
Company’s convertible preferred stock, in the event that all outstanding shares of the Class are converted, automatically or by action of the holders thereof, into common stock pursuant to the provisions of the Company’s Certificate
of Incorporation, including, without limitation, in connection with the Company’s initial, underwritten public offering and sale of its common stock pursuant to an effective registration statement under the Act (the
“IPO”), then from and after the date on which all outstanding shares of the Class have been so converted, this Warrant shall be exercisable for such number of shares of common stock into which the Shares would have been
converted had the Shares been outstanding on the date of such conversion, and the Warrant Price shall equal the Warrant Price in effect as of immediately prior to such conversion divided by the number of shares of common stock into which one Share
would have been converted, all subject to further adjustment thereafter from time to time in accordance with the provisions of this Warrant. 

2.4 Adjustments for Diluting Issuances. Except as would duplicate any adjustment otherwise provided for in this Section 2, the
number of shares of common stock issuable upon conversion of the Shares shall be subject to anti-dilution adjustment from time to time in the manner set forth in the Company’s Certificate of Incorporation as if the Shares were issued and
outstanding on and as of the date of any such required adjustment. 
 2.5 No Fractional Share. No fractional Share shall
be issuable upon exercise of this 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 of the Warrant, the Company shall eliminate such fractional
Share interest by paying Holder in cash the amount computed by multiplying the fractional interest by (i) the fair market value (as determined in accordance with Section 1.3 above) of a full Share, less (ii) the then-effective Warrant
Price. 
 2.6 Notice/Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of Shares, the
Company, at the Company’s expense, shall notify Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, Class and/or number of Shares and facts upon which such adjustment is based. The Company shall,
upon written request from Holder, furnish Holder with a certificate of its Chief Financial Officer, including computations of such adjustment and the Warrant Price, Class and number of Shares in effect upon the date of such adjustment. 

SECTION 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY. 

3.1 Representations and Warranties. The Company represents and warrants to, and agrees with, the Holder as follows: 

(a)The initial Warrant Price referenced on the first page of this Warrant is not greater than the price per share at which shares of the

 5 








 (b)All Shares which may be issued upon the exercise of this Warrant, and all securities, if any,
issuable upon conversion of the Shares, shall, upon issuance, be duly authorized, validly issued, fully paid and non-assessable, and free of any liens and encumbrances except for restrictions on transfer
provided for herein or under applicable federal and state securities laws. The Company covenants that it shall at all times cause to be reserved and kept available out of its authorized and unissued capital stock such number of shares of the Class,

(c)The Company’s capitalization table attached hereto as Schedule 1 is true and complete, in all material respects, as of the Issue Date.

 3.2 Notice of Certain Events. If the Company proposes at any time to: 

(a) declare any dividend or distribution upon the outstanding shares of the Class or common stock, whether in cash, property, stock, or
other securities and whether or not a regular cash dividend;

outstanding shares of the Class any additional shares of any class or series of the Company’s stock (other than pursuant to contractual pre-emptive rights); 

(c) effect any reclassification, exchange, combination, substitution, reorganization or recapitalization of the outstanding shares of the
Class; 
 (d) effect an Acquisition or to liquidate, dissolve or wind up; or 

(e) effect an IPO; 
 then, in connection with
each such event, the Company shall give Holder:

on which a record will be taken for such dividend, distribution, or subscription rights (and specifying the date on which the holders of outstanding shares of the Class will be entitled thereto) or for determining rights to vote, if any, in
respect of the matters referred to in (a) and (b) above; 
 (2) in the case of the matters referred to in (c) and
(d) above at least seven (7) Business Days prior written notice of the date when the same will take place (and specifying the date on which the holders of outstanding shares of the Class will be entitled to exchange their shares for the
securities or other property deliverable upon the occurrence of such event); and 
 (3) with respect to the IPO, at least
seven (7) Business Days prior written notice of the date on which the Company proposes to file its registration statement in connection therewith. 

Reference is made to Section 1.6(c) whereby this Warrant will be deemed to be exercised pursuant to Section 1.2 hereof if the Company does not give
written notice to Holder of a Cash/Public Acquisition as required by the terms hereof. Company will also provide information requested by Holder that is reasonably necessary to enable Holder to comply with Holder’s accounting or reporting
requirements.

 SECTION 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER. 

The Holder represents and warrants to the Company as follows: 

4.1 Purchase for Own Account. This Warrant and the Shares issuable upon exercise of this Warrant (and the securities issuable, directly
or indirectly, upon conversion of the Shares, if any) are being acquired for investment for Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also
represents that it has not been formed for the specific purpose of acquiring this Warrant or the Shares (or the securities issuable, directly or indirectly, upon conversion of the Shares, if any). 

4.2 Disclosure of Information. Holder is aware of the Company’s business affairs and financial condition and has received or has
had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask
questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company possessed such information or could
acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access. 

4.3 Investment Experience. Holder understands that the purchase of this Warrant and its underlying securities involves substantial risk.
Holder has experience as an investor in securities of companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder’s investment in this Warrant and its underlying securities and has such knowledge
and experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities and/or has a preexisting personal or business relationship with the Company and
certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons. 

4.4 Accredited Investor Status. Holder is an “accredited investor” within the meaning of Regulation D promulgated under the
Act. 
 4.5 The Act. Holder understands that this Warrant and the Shares issuable upon exercise hereof (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s
investment intent as expressed herein. Holder understands that this Warrant and the Shares issued upon any exercise hereof (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) must be held indefinitely unless
subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from such registration and qualification are otherwise available. Holder is aware of the provisions of Rule 144 promulgated under the
Act. 
 4.6 Market Stand-off Agreement. The Holder agrees that the Shares shall be subject to
the market standoff provisions in Section 2.7 of the Company’s Investor Rights Agreement or similar agreement.

to time on or before 6:00 PM, Pacific time, on the Expiration Date and shall be void thereafter. 
 (b) Automatic Cashless Exercise 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 1.3 above is greater than the Warrant Price in effect
on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised, and the
Company shall, within a reasonable time, deliver a certificate representing the Shares (or such other securities) issued upon such exercise to Holder. 

5.2 Legends. The Shares (and the securities issued, directly or indirectly, upon conversion of the Shares, if any) shall be imprinted
with a legend in substantially the following form: 
 THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT AS SET FORTH IN THAT CERTAIN WARRANT TO PURCHASE STOCK ISSUED BY THE ISSUER TO SILICON VALLEY BANK DATED JUNE 28, 2013, MAY NOT BE
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND LAWS OR IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER, SUCH OFFER, SALE, PLEDGE OR OTHER TRANSFER IS EXEMPT FROM SUCH REGISTRATION. 

5.3 Compliance with Securities Laws on Transfer. This Warrant and the Shares issued upon exercise of this Warrant (and the securities
issued, directly or indirectly, upon conversion of the Shares, if any) may not be transferred or assigned in whole or in part except in compliance with applicable federal and state securities laws by the transferor and the transferee (including,
without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the
transfer is to SVB Financial Group (Silicon Valley Bank’s parent company) or any other affiliate of Holder, provided that any such transferee is an “accredited investor” as defined in Regulation D promulgated under the Act.
Additionally, the Company shall also not require an opinion of counsel if the Company and Holder agree that there is no material question as to the availability of Rule 144 promulgated under the Act. 

5.4 Transfer Procedure. After receipt by Silicon Valley Bank of the executed Warrant, Silicon Valley Bank will transfer all of this
Warrant to its parent company, SVB Financial Group, provided that such transfer shall be conditioned upon SVB Financial Group delivering a duly executed signature page to the Option and Support Agreement to the Company. By its acceptance of this
Warrant, SVB Financial Group hereby makes to the Company each of the representations and warranties set forth in Section 4 hereof and agrees to be bound by all of the terms and conditions of this Warrant as


  
 8 








 
if it were the original Holder hereof. Subject to the provisions of Section 5.3 and upon providing the Company with written notice, SVB Financial Group and any subsequent Holder may transfer
all or part of this Warrant or the Shares issued upon exercise of this Warrant (or the securities issued directly or indirectly, upon conversion of the Shares, if any) to any transferee, provided, however, in connection with any such transfer, SVB
Financial Group or any subsequent Holder will give the Company notice of the portion of the Warrant or the Shares issued upon exercise of this Warrant (or the securities issued, directly or indirectly, upon conversion of the Shares, if any) being
transferred with the name, address and taxpayer identification number of the transferee and will surrender this Warrant (and/or the stock certificates representing the Shares issued upon the exercise of this Warrant (or the securities issued
directly or indirectly, upon conversion of the Shares, if any) being transferred) to the Company for reissuance to the transferee(s) (and Holder if applicable); and provided further, that any subsequent transferee other than SVB Financial Group
(which shall, for the avoidance of doubt, have already delivered a duly executed signature page to the Option and Support Agreement to the Company as provided above) shall deliver a duly executed signature page to the Option and Support Agreement to
the Company and agree in writing with the Company to be bound by all of the terms and conditions of this Warrant or to which the Shares issued upon exercise of this Warrant (or the securities issued directly or indirectly, upon conversion of the
Shares, if any) being transferred are then subject, as applicable. Notwithstanding any contrary provision herein, at all times prior to the IPO, Holder may not, without the Company’s prior written consent, transfer this Warrant or any portion
hereof, or any Shares issued upon any exercise hereof, or any shares or other securities issued directly or indirectly upon any conversion of any Shares issued upon any exercise hereof, to any person or entity who directly competes with the Company,

option and support agreement substantially in the form of this Agreement, pursuant to a stock purchase agreement, the form of which will contain terms that are consistent in all material respects with the Merger Agreement (the “Option”);

 WHEREAS, Parent, Hydra Acquisition Corp., a Delaware corporation (“AcquisitionCo”), the Company, and Robert Tepper M.D.,
as representative of Third Rock Ventures, as representative of the Participating Equity Holders, have entered into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), which provides, upon the terms and
subject to the conditions thereof, for the merger (the “Merger”) of AcquisitionCo with and into the Company, with the Company continuing as the surviving corporation in the Merger; and 

WHEREAS, as an inducement to Parent to enter into the Option Agreement and the Merger Agreement, Parent has requested that Stockholder
enter into, and in order to induce Parent to enter into the Option Agreement and the Merger Agreement, Stockholder has agreed to enter into, certain arrangements with respect to approval of the Option and the Merger. 

NOW, THEREFORE, in consideration of the mutual premises set forth herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Termination of Agreement. This
Agreement shall terminate upon the termination of the Merger Agreement in accordance with the terms thereof; provided, however, that nothing in this Section 1 shall relieve any party of liability for any breach of this Agreement. 

2. Support. 
 2.1.
Ownership of Company Securities. Exhibit A hereto sets forth all of the securities of the Company beneficially owned by Stockholder. 
 2.2.
Voting Agreement. Stockholder, by this Agreement, with respect to all of the shares of common stock or preferred stock of the Company owned or hereafter acquired by Stockholder (collectively, the “Shares”), hereby covenants and agrees to
vote or cause to be voted, at any meeting of stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, all of the Shares in favor of the adoption of the Option Agreement and the Merger
Agreement and the approval of the Option, the Merger, and all of the transactions contemplated by the Option Agreement and the Merger Agreement, including the acquisition of all of the equity interests of the Company by Parent or its affiliates in
the form of a stock purchase agreement, and against any Acquisition Proposal (as defined in the Option Agreement) or any other proposal pursuant to which any Person would acquire Shares that would reasonably be expected to prevent, delay, or
postpone the transactions contemplated by the Option Agreement or the Merger Agreement. 
 2.3. Transfer of Shares. Stockholder agrees not
to, directly or indirectly, at any time prior to the Effective Time, other than as may be required by a court order, (a) sell, assign, transfer (including by operation of law), pledge, dispose of or otherwise encumber any of the Shares or
otherwise agree to do any of the foregoing (a “Transfer”) unless the recipient of such shares, as a condition to such Transfer, executes and delivers to Parent a Stockholder Option and Support Agreement in the form of this Agreement,
(b) deposit any Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or (c) enter into any contract, option or
other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer (including by operation of law) or other disposition by Stockholder of any Shares unless the recipient of such shares,








 
as a condition to such Transfer, executes and delivers to Parent a Stockholder Option and Support Agreement in the form of this Agreement. Any Transfer or attempted Transfer of any Shares in
violation of any provision of this Agreement shall be void and of no force or effect, and the Company shall not record such Transfer on its books or treat any purported transferee of such Shares as the owner of such shares for any purpose. 

2.4. Legend. Concurrently with the execution of this Agreement, there shall be imprinted or otherwise placed, on certificates representing
shares of common stock or preferred stock of the Company, the following restrictive legend (the “Legend”): 
 “THE
SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A STOCKHOLDER OPTION AND SUPPORT AGREEMENT WHICH PLACES CERTAIN RESTRICTIONS ON THE VOTING AND TRANSFER OF THE SHARES REPRESENTED HEREBY. ANY PERSON ACCEPTING ANY
INTEREST IN SUCH SHARES SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SUCH AGREEMENT. A COPY OF SUCH STOCKHOLDER OPTION AND SUPPORT AGREEMENT WILL BE FURNISHED TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT CHARGE
UPON WRITTEN REQUEST TO THE COMPANY AT ITS PRINCIPAL PLACE OF BUSINESS.” 
 The Company agrees that, during the term of this Agreement,
it will not remove, and will not permit to be removed (upon registration of transfer, reissuance or otherwise), the Legend from any such certificate and will place or cause to be placed the Legend on any new certificate representing shares of common
stock or preferred stock of the Company issued. 
 2.5. Stock Purchase Agreement. In the event that Parent or its affiliates exercise
the Option and pursuant thereto elect to acquire equity interests of the Company pursuant to a stock purchase agreement, the form of which will contain terms that are consistent in all material respects with the terms of the Merger Agreement (the
“Stock Purchase Agreement”), Stockholder agrees that it shall enter into the Stock Purchase Agreement, pursuant to which Stockholder will agree to sell all of its Shares to Parent or its affiliates on such terms, and to take such other
actions, in each case that are consistent with the Stock Purchase Agreement, as may reasonably be required by Parent to effect the acquisition of the Company by Parent, including the provision of information customarily provided by a stockholder in
connection with such a transaction and the execution of customary conveyance instruments. 
 3. Notices. All notices, requests,
claims, demands and other communications under this Agreement will be in writing and will be deemed given if delivered personally, when sent by receipt requested electronic mail, or the next business bay if sent by overnight courier (providing proof
of delivery), or on the same business day if sent via facsimile on a business day during normal business hours to the parties at the following addresses (or at such other address for a party as specified by like notice), or to such other address as

4. Miscellaneous. 

4.1. Entire Agreement; Amendments. This Agreement contains the entire understanding of the parties hereto with regard to the subject matter
hereof and supersedes all other prior agreements or understandings between the parties hereto. This Agreement shall not be amended, modified or supplemented except by a written instrument signed by Stockholder and an authorized representative of
Parent. 
 4.2. Confidentiality. Stockholder shall hold any information regarding this Agreement, the Option, the Option Agreement, the
Merger, the Merger Agreement and the transactions contemplated hereby and thereby (the “Confidential Information”) in strict confidence and shall not divulge any such information to any third person unless otherwise so required by a court
of competent jurisdiction; provided, that if Stockholder is not a natural person and has a fiduciary or contractual duty to disclose any Confidential Information to its limited partners or members, Stockholder shall be permitted to disclose such
Confidential Information to its limited partners or members, provided that Stockholder first informs such limited partners or members that such Confidential Information is confidential and directs such limited partner or member to maintain the
confidentiality of such information in accordance with the terms of this Agreement. Neither the Stockholder nor any of its affiliates shall issue or cause the publication of any press release or other public statement with respect to this Agreement,
the Option, the Option Agreement, the Merger, the Merger Agreement and the transactions contemplated hereby and thereby without the prior written consent of Parent. 

4.3. Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such manner as to be effective and valid under
applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision shall be ineffective to the extent, but only to the extent, of such
invalidity, illegality or unenforceability without invalidating the remainder of such invalid, illegal or unenforceable provision or provisions or any other provision hereof, unless such a construction would be unreasonable. 

4.4. Waivers. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the party or parties
entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this Agreement if, as to any party, it is authorized in writing by an authorized representative of such party. The failure of any party
hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any party thereafter to enforce each
and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. 

4.5. Binding Effect; Assignment. Parent may assign its rights and obligations under this Agreement to any of Parent’s affiliates without
the consent of Stockholder. Stockholder’s rights or obligations under this Agreement may not be assigned. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their successors and permitted assigns. The
successors and permitted assigns hereunder shall include, in the case of Parent, any assignee as well as the successors in interest to such assignee (whether by merger, liquidation (including successive mergers or liquidations) or otherwise).
Nothing in this Agreement, expressed or implied, is intended or shall be construed to confer upon any person or entity other than the parties, their successors and assigns permitted by this Section 4.5 any right, remedy or claim under or by
reason of this Agreement. 
 4.6. Headings. The headings contained in this Agreement are for convenience of reference only and shall not be
deemed a part of or to affect the meaning or interpretation of this Agreement. 
 4.7. Governing Law. This Agreement shall be construed in
accordance with, and governed in all respects by, the internal laws of the State of Delaware (without giving effect to principles of conflicts of laws). 







 4.8. Jurisdiction. Any legal proceeding relating to this Agreement or the enforcement of any
provision of this Agreement (including a legal proceeding based upon intentional misrepresentation or fraud) may be brought or otherwise commenced in the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have
jurisdiction, a federal court sitting in Wilmington, Delaware. Each party to this Agreement hereby irrevocably: (a) consents to submit itself in any suit, action or proceeding arising out of or related to this Agreement to the exclusive
personal jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware; (b) agrees that it will not attempt to defeat or deny
such personal jurisdiction by motion or other request for leave from such court; and (c) agrees that it will not bring any action arising out of or related to this Agreement in any court other than any such court. 

4.9. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF. 

4.10. Execution in Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be considered an original
instrument, but all of which shall be considered one and the same agreement, and shall become binding when each party to this Agreement has executed a counterpart to this Agreement and delivered such counterpart to the other party to this Agreement.

 4.11. Interpretation. For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and
vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders. The undersigned hereto agrees
that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement. As used in this Agreement, the words “include” and
“including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” For purposes of this Agreement, the use of the word “or”
shall not be exclusive. Except as otherwise indicated, all references in this Agreement to “Sections” are intended to refer to Sections of this Agreement.
