and warrants that: 
 3.1 Authorization. Such Investor has full power and authority to enter into this
Agreement and the Amendment, and each such Agreement constitutes its valid and legally binding obligation, enforceable in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and
other laws of general application affecting enforcement of creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies. 

3.2 Purchase Entirely for Own Account. This Agreement is made with such Investor in reliance upon such
Investor’s representation to the Company, which by such Investor’s execution of this Agreement such Investor hereby confirms, that the Shares to be received by such Investor and the Conversion Shares (collectively, the
“Securities”) will be acquired for investment for such Investor’s own account, not as a nominee or agent, and not with a view to the distribution of any part thereof, and that such Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same. By executing this Agreement, such Investor further represents that such Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer
or grant participations to such person or to any third person, with respect to any of the Securities. 
 3.3
Disclosure of Information. Such Investor believes it has received all the information it considers necessary or appropriate for deciding whether to purchase the Shares. Such Investor further represents that it has had an opportunity to ask
questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares and the business, properties, prospects and financial condition of the Company. The foregoing, however, does not limit or modify the
representations and warranties of the Company in Section 2 of this Agreement or the right of the Investors to rely thereon. 

  
 4 








 3.4 Investment Experience. Such Investor is an investor in
securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of
evaluating the merits and risks of the investment in the Shares. If other than an individual, Investor also represents it has not been organized for the purpose of acquiring the Shares. 

3.5 Accredited Investor. Such Investor is an “accredited investor” within the meaning of Securities and
Exchange Commission (“SEC”) Rule 501 of Regulation D, as presently in effect. 
 3.6
Restricted Securities. Such Investor understands that the Securities will be characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Act, only in certain limited circumstances. In this connection, such Investor represents that it is familiar
with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Act. 
 3.7 Further Limitations on Disposition. Without in any way limiting the representations set forth above, such Investor further agrees not to make any disposition of all or any portion of the
Securities unless and until: 
 (a) There is then in effect a Registration Statement under the Act covering
such proposed disposition and such disposition is made in accordance with such Registration Statement; or 

(b)(i) Such Investor shall have notified the Company of the proposed disposition and shall have furnished the
Company with a detailed statement of the circumstances surrounding the proposed disposition, and (ii) if reasonably requested by the Company, such Investor shall have furnished the Company with an opinion of counsel, reasonably satisfactory to
the Company that such disposition will not require registration of such shares under the Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances. 

(c) Notwithstanding the provisions of subsections (a) and (b) above, no such registration statement or opinion
of counsel shall be necessary for a transfer by an Investor that is a partnership to an affiliated venture fund or a partner of such partnership, or to the estate of any such partner or the transfer by gift, will or intestate succession of any
partner to his or her spouse or to the siblings, lineal descendants or ancestors of such partner or his or her spouse, if the prospective transferee agrees in all such instances in writing to be subject to the terms hereof to the same extent as if
he or she were an original Investor hereunder. 
 3.8 Legends. It is understood that the certificates
evidencing the Securities may bear one or all of the following legends: 
 (a) “THESE SECURITIES HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY 

  
 5 








 
NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO
THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.” 

(b) Any legend required by applicable state “blue sky” securities laws, rules and regulations. 

3.9 Exculpation Among Investors. Each Investor acknowledges that it is not relying upon any person, firm or
corporation, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. Each Investor agrees that no Investor nor the respective controlling persons, officers, directors, partners, agents,
or employees of any Investor shall be liable to any other Investor for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Securities. 

4. Conditions of Investors’ Obligations at Closing. The obligations of each Investor under

only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative. 

6.16 Arbitration. The Company and the other parties hereto agree first to negotiate in good faith to resolve any
disputes arising out of or relating to or affecting the subject matter of this Agreement. Any dispute arising out of or relating to or affecting the subject matter of this Agreement not resolved by negotiation shall be settled by binding arbitration
in Santa Clara County, California before the Judicial Arbitration and Mediation Services, Inc. (“JAMS”) under the JAMS Rules of Practice and Procedure. The arbitrator shall be a former judge of a court of California. Discovery and
other procedural matters shall be governed as though the proceeding were an arbitration. Any judgment upon the award may be confirmed and entered in any court having jurisdiction thereof. The arbitrator shall be required to, in all determinations,
apply California law without regard to its conflicts of law provisions. Notwithstanding the foregoing, the arbitrator shall apply the substantive law of the state of incorporation of the Company, where applicable or where indicated by the terms of
this Agreement. The arbitrator is afforded the jurisdiction to order any provisional remedies, including, without limitation, injunctive relief. The arbitrator may award the prevailing party the


  
 9 








 
costs of arbitration, including reasonable attorneys’ fees and expenses. The arbitrator’s award shall be in writing and shall state the reasons for the award. The Company and the other
parties hereto stipulate that a JAMS employee may be appointed as a judge pro tempore of the Superior Court of Santa Clara County if required to carry out the terms of this provision. Arbitration shall be the sole and exclusive means to resolve any
dispute. 
 6.17 Waiver of Conflicts. Each party to this Agreement acknowledges that Gunderson Dettmer,
counsel for the Company, has in the past and may continue to perform legal services for certain of the Investors in matters unrelated to the transactions described in this Agreement, including the representation of such Investors in venture capital
