such Investor of the Transaction Documents to which such Investor is a party have been duly authorized and each has been duly executed and when delivered will constitute the valid and legally binding obligation of such Investor, enforceable against
such Investor in accordance with their respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability, relating to or affecting creditors’ rights generally. 

5.3.    Purchase Entirely for Own Account. The Pre-Funded Warrants to be
received by such Investor hereunder will be acquired for such Investor’s own account, not as nominee or agent, for the purpose of investment and not with a view to the resale or distribution of any part thereof in violation of the 1933 Act, and
such Investor has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of the 1933 Act without prejudice, however, to such Investor’s right at all times to sell or otherwise dispose of
all or any part of such Pre-Funded Warrants in compliance with applicable federal and state securities laws. The Pre-Funded Warrants are being purchased by such Investor
in the ordinary course of its business. Nothing contained herein shall be deemed a representation or warranty by such Investor to hold the Pre-Funded Warrants for any period of time. Such Investor is not a
broker-dealer registered with the SEC under the 1934 Act or an entity engaged in a business that would require it to be so registered. 

5.4.    Investment Experience. Such Investor acknowledges that it can bear the economic risk and complete loss of
its investment in the Pre-Funded Warrants and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment contemplated hereby.

 5.5.    Disclosure of Information. Such Investor has had an opportunity to receive, review and understand all
information related to the Company requested by such Investor and to ask questions of and receive answers from the Company regarding the Company, its business and the terms and conditions of the offering of the
Pre-Funded Warrants, and has conducted and completed such Investor’s own independent due diligence. Such Investor acknowledges that copies of the SEC Filings are available on the EDGAR system. Based on
the information such Investor has deemed appropriate, it has independently made its own analysis and decision to enter into the Transaction Documents. Such Investor is relying exclusively on its own sources of information, investment analysis and
due diligence (including professional advice it deems appropriate) with respect to the execution, delivery and performance of the Transaction Documents, the Pre-Funded Warrants and the business, condition
(financial and otherwise), management, operations, properties and prospects of the Company, including but not limited to all business, legal, regulatory, accounting, credit and tax matters. Neither such inquiries nor any other due diligence
investigation conducted by such Investor shall modify, limit or otherwise affect such Investor’s right to rely on the Company’s representations and warranties contained in this Agreement. 

  
 16 

 5.6.    Restricted Securities. Such Investor understands that the
Pre-Funded Warrants and Warrant Shares are characterized as “restricted securities” under the U.S. 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 1933 Act only in certain limited circumstances. 

5.7.    Legends. It is understood that, except as provided below, certificates or book-entry records evidencing the
Pre-Funded Warrants and Warrant Shares may bear the following or any similar legend: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES
COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND, ACCORDINGLY, MAY NOT BE TRANSFERRED UNLESS (I) SUCH SECURITIES HAVE BEEN REGISTERED FOR SALE PURSUANT TO THE SECURITIES
ACT OF 1933, AS AMENDED, (II) SUCH SECURITIES MAY BE SOLD PURSUANT TO RULE 144, OR (III) THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH TRANSFER MAY LAWFULLY BE MADE WITHOUT REGISTRATION UNDER
THE SECURITIES ACT OF 1933, AS AMENDED.” 
 If required by the authorities of any state in connection with the issuance or sale of the Pre-Funded Warrants and Warrant Shares, the legend required by such state authority. 

5.8.    Accredited Investor. Such Investor is an “accredited investor” within the meaning of Rule 501
under the 1933 Act and has executed and delivered to the Company a questionnaire in substantially the form attached hereto as Exhibit D (the “Investor Questionnaire”), which such Investor represents and warrants is true,
correct and complete. Such investor is a sophisticated institutional investor with sufficient knowledge and experience in investing in private equity transactions to properly evaluate the risks and merits of its purchase of the Pre-Funded Warrants. Such Investor has determined based on its own independent review and such professional advice as it deems appropriate that its purchase of the Pre-Funded
Warrants and participation in the transactions contemplated by the Transaction Documents (i) are fully consistent with its financial needs, objectives and condition, (ii) comply and are fully consistent with all investment policies,
guidelines and other restrictions applicable to such Investor, (iii) have been duly authorized and approved by all necessary action, (iv) do not and will not violate or constitute a default under such Investor’s charter, bylaws or
other constituent document or under any law, rule, regulation, agreement or other obligation by which such Investor is bound and (v) are a fit, proper and suitable investment for such Investor, notwithstanding the substantial risks inherent in
investing in or holding the Pre-Funded Warrants. Such Investor understands that the Pre-Funded Warrants are being offered and sold to it in reliance upon specific
exemptions from the registration requirements of the Securities Act and state securities laws, and that the Company is relying upon the truth and accuracy of, and 

  
 17 

 
such Investor’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Investor set forth herein in order to determine the availability of
such exemptions and the eligibility of such Investor to acquire the Pre-Funded Warrants.

shares of capital stock of the Company as set forth in the Investor Questionnaire.

Investor was invited by any of the foregoing means of communications. 
 5.11.    Brokers and Finders. No Person
will have, as a result of the transactions contemplated by the Transaction Documents, any valid right, interest or claim against or upon the Company or an Investor for any commission, fee or other compensation pursuant to any agreement, arrangement
or understanding entered into by or on behalf of such Investor. 
 5.12.    Short Sales and Confidentiality Prior to
the Date Hereof. Other than consummating the transactions contemplated hereunder, such Investor has not, nor has any Person acting on behalf of or pursuant to any understanding with such Investor, directly or indirectly executed any purchases or
sales, including Short Sales, of the securities of the Company during the period commencing as of the time that such Investor was first contacted by the Company or any other Person regarding the transactions contemplated hereby and ending
immediately prior to the date hereof. Notwithstanding the foregoing, in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the
portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the representation set forth above shall only apply with respect to the portion of assets
managed by the portfolio manager that made the investment decision to purchase the Pre-Funded Warrants covered by this Agreement. Other than to other Persons party to this Agreement and other than to such
Person’s outside attorney, accountant, auditor or investment advisor only to the extent necessary to permit evaluation of the investment, and the performance of the necessary or required tax, accounting, financial, legal, or administrative
tasks and services and other than as may be required by law, such Investor has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding
the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to
effect Short Sales or similar transactions in the future. 
 5.13.     No Government Recommendation or Approval.
Such Investor understands that no United States federal or state agency, or similar agency of any other country, has reviewed, approved, passed upon, or made any recommendation or endorsement of the Company or the purchase of the Pre-Funded Warrants. 

  
 18 

 5.14.    No Conflicts. The execution, delivery and performance by
such Investor of the Transaction Documents and the consummation by such Investor of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Investor or (ii) conflict with,
or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which
such Investor is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Investor, except in the case of clauses (ii) and (iii) above,
for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Investor to perform its obligations hereunder. 

5.15.    Residency. Such Investor is a resident of the jurisdiction specified below its address on the Schedule of
Investors in Exhibit A hereto. 
 5.16.    No Legal, Tax or Investment Advice. Such Investor understands

advice. Such Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Pre-Funded Warrants.

that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the 1933 Act) that will be integrated with the offer or sale of the Pre-Funded Warrants in a manner that would require the registration under the 1933 Act of the sale of the Pre-Funded Warrants to the Investors, or that will be integrated with
the offer or sale of the Pre-Funded Warrants for purposes of the rules and regulations of any trading market such that it would require stockholder approval prior to the closing of such other transaction
unless stockholder approval is obtained before the closing of such subsequent transaction. 
 7.4.    Short Sales and
Confidentiality After the Date Hereof. Each Investor covenants that neither it nor any Affiliates acting on its behalf or pursuant to any understanding with it will execute any Short Sales during the period from the date hereof until the earlier
of such time as (i) after the transactions contemplated by this Agreement are first publicly announced or (ii) this Agreement is terminated in full. Each Investor covenants that until such time as the transactions contemplated by this
Agreement are publicly disclosed by the Company, such Investor will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Each Investor understands and
acknowledges that the SEC currently takes the position that coverage of short sales of shares of the Common Stock “against the box” prior to effectiveness of a resale

registration statement with securities included in such registration statement would be a violation of Section 5 of the 1933 Act, as set forth in Item 239.10 of the 1933 Act Rules Compliance
and Disclosure Interpretations compiled by the Office of Chief Counsel, Division of Corporation Finance. 

8.    Survival and Indemnification. 

8.1.    Survival. The representations, warranties, covenants and agreements contained in this Agreement shall
survive the Closing of the transactions contemplated by this Agreement for the applicable statute of limitations. 

8.2.    Indemnification. The Company agrees to indemnify and hold harmless each Investor and its Affiliates and
their respective directors, officers, trustees, members, managers, employees and agents, and their respective successors and assigns, from and against any and all losses, claims, damages, liabilities and expenses (including without limitation
reasonable and documented attorney fees and disbursements and other documented out-of-pocket expenses reasonably incurred in connection with investigating, preparing or
defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, “Losses”) to which such Person may become subject as a result of any breach of representation, warranty, covenant or
agreement made by or to be performed on the part of the Company under the Transaction Documents, and will reimburse any such Person for all such amounts as they are incurred by such Person solely to the extent such amounts have been finally
judicially determined not to have resulted from such Person’s fraud or willful misconduct. 
 8.3.    Conduct of
Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such
indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to
participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed in writing to pay such fees or expenses, (b) the indemnifying party
shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists
between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give written notice as provided herein shall not relieve the
indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying
party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent
of the indemnified party, which consent shall not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or
plaintiff to 

  
 23 

 
such indemnified party of a release from all liability in respect of such claim or litigation. No indemnified party will, except with the consent of the indemnifying party, which consent shall
not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement. 

9.    Miscellaneous. 

9.1.    Successors and Assigns. This Agreement may not be assigned by a party hereto without the prior written
consent of the Company or the Investors, as applicable, provided, however, that an Investor may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring some or all of its Pre-Funded Warrants in a transaction complying with applicable securities laws without the prior written consent of the Company or the other Investors, provided such assignee agrees in writing to be bound by the
provisions hereof that apply to Investors. The provisions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Without limiting the generality of the foregoing, in the
event that the Company is a party to a merger, consolidation, share exchange or similar business combination transaction in which the Common Stock is converted into the equity securities of another Person, from and after the effective time of such
transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term
“Pre-Funded Warrants” shall be deemed to refer to the securities received by the Investors in connection with such transaction. Nothing in this Agreement, express or implied, is intended to confer
upon any party other than the parties hereto or their respective permitted successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 

9.2.    Counterparts; Faxes; E-mail. This Agreement may be executed in one
or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may also be executed via facsimile or e-mail, which shall
be deemed an original. 
 9.3.    Titles and Subtitles. The titles and subtitles used in this Agreement are used
for convenience only and are not to be considered in construing or interpreting this Agreement.

writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery, (ii) if given by facsimile or
e-mail, then such notice shall be deemed given upon receipt of confirmation of complete transmittal or confirmation of receipt of an e-mail transmission, (iii) if
given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an

9.5.    Expenses. The parties hereto shall pay their own costs and expenses in connection herewith regardless of

this Agreement against another party to this Agreement in connection with this Agreement or the other Transaction Documents, the party or parties which do not prevail in such proceedings shall severally, but not jointly, pay their pro rata share of
the reasonable attorneys’ fees and other reasonable documented out-of-pocket costs and expenses incurred by the prevailing party in such proceedings. 

9.6.    Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and (a) prior to the Closing, Investors that agreed to purchase a majority of the Pre-Funded Warrants to be issued and sold pursuant to this Agreement and (b) following the Closing, the Required Investors. Notwithstanding the foregoing, this Agreement may not be amended and the observance of
any term of this Agreement may not be waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. Any amendment or waiver effected in accordance with
this paragraph shall be binding upon (i) prior to Closing, each Investor and (ii) following the Closing, each holder of any Pre-Funded Warrants purchased under this Agreement or Warrant Shares at the
time outstanding, and in each case, each future holder of all such Pre-Funded Warrants and Warrant Shares and the Company. 

9.7.    Publicity. Except as set forth below, no public release or announcement concerning the transactions
contemplated hereby shall be issued by the Investors without the prior consent of the Company, except as such release or announcement may be required by law 

  
 25 

 
or the applicable rules or regulations of any securities exchange or securities market, in which case the Investors shall allow the Company reasonable time to comment on such release or
announcement in advance of such issuance. Notwithstanding the foregoing, each Investor may identify the Company and the value of such Investor’s security holdings in the Company in accordance with applicable investment reporting and disclosure
regulations or internal policies without prior notice to or consent from the Company (including, for the avoidance of doubt, filings pursuant to Sections 13 and 16 of the 1934 Act). By 8:30 a.m. (New York City time) on the Business Day immediately
following the date this Agreement is executed, the Company shall issue a press release or file a Current Report on Form 8-K disclosing all material terms of the sale of the
Pre-Funded Warrants to the Investors pursuant to this Agreement (the “Public Disclosure”). In addition, the Company will make such other filings and notices in the manner and time required by
the SEC or Nasdaq. The Company shall not include the name of any Investor in the Public Disclosure or any other public announcement without the prior written consent of such Investor, except as otherwise required by law, rule, regulation or
applicable SEC guidance. From and after the issuance of the Public Disclosure, no Investor shall be in possession of any material non-public information received from the Company or any of their respective
officers, directors, employees or agents in connection with the transactions contemplated by this Agreement. 

9.8.    Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent
permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive
any provision of law which renders any provision hereof prohibited or unenforceable in any respect. 
 9.9.    Entire
Agreement. This Agreement, including the signature pages, Exhibits, and the other Transaction Documents constitute the entire agreement among the parties hereof with respect to the subject matter hereof and thereof and supersede all prior
agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof. 

9.10.    Further Assurances. The parties shall execute and deliver all such further instruments and documents and
take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained. 

9.11.    Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and
construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York
located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby.
Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the 

  
 26 

 
same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or
proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action
or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN
CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 9.12.    Independent Nature of Investors’ Obligations and
Rights. The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other
Investor under any Transaction Document. The decision of each Investor to purchase Pre-Funded Warrants pursuant to the Transaction Documents has been made by such Investor independently of any other Investor.
Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a
presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for
such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Pre-Funded Warrants or
enforcing its rights under the Transaction Documents. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents,
and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of
closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor. 

9.13.    Limitation of Liability. Notwithstanding anything herein to the contrary, the Company acknowledges and
agrees that the liability of an Investor arising directly or indirectly under any Transaction Document of any and every nature whatsoever shall be satisfied solely out of the assets of such Investor and that no trustee, officer, other investment
vehicle or any other Affiliate of such Investor or any investor, shareholder or holder of shares of beneficial interest of such Investor shall be personally liable for any liabilities of such Investor.

Please fill in all blanks in the following questions related to your beneficial ownership of the Company’s capital
stock. Generally, the term “beneficial ownership” refers to any direct or indirect interest in the securities which entitles you to any of the rights or benefits of ownership, even though you may not be the holder of record
of the securities. For example, securities held in “street name” over which you exercise voting or investment power would be considered beneficially owned by you. Another example of indirect ownership include ownership by a
partnership in which you are a partner. 

 

 PLEASE NOTE: IF YOU
HAVE ANY REASON TO BELIEVE THAT ANY INTEREST IN SECURITIES OF THE
COMPANY WHICH YOU MAY HAVE, HOWEVER REMOTE, IS A BENEFICIAL INTEREST,
PLEASE DESCRIBE SUCH INTEREST. FOR PURPOSES OF RESPONDING TO THIS QUESTIONNAIRE,
IT IS PREFERABLE TO ERR ON THE SIDE OF INCLUSION RATHER THAN
EXCLUSION. WHERE THE SEC’S INTERPRETATION OF BENEFICIAL OWNERSHIP
WOULD REQUIRE DISCLOSURE OF YOUR INTEREST OR POSSIBLE INTEREST IN CERTAIN
SECURITIES OF THE COMPANY, AND YOU BELIEVE THAT YOU DO NOT ACTUALLY
POSSESS THE ATTRIBUTES OF BENEFICIAL OWNERSHIP, AN APPROPRIATE RESPONSE IS TO
DISCLOSE THE INTEREST AND AT THE SAME TIME DISCLAIM BENEFICIAL OWNERSHIP
OF THE SECURITIES (SPACE IF PROVED TO DISCLAIM BENEFICIAL OWNERSHIP AT THE END OF 3 BELOW). 

1.    As of MAY 1, 2022, the undersigned owned
outright (including shares registered in the undersigned’s name individually or jointly with others, shares held in the name of a bank, broker, nominee, depository or in “street name” for my account), the following number of shares of
the Company’s capital stock (none indicated by “0”):                     . 

2.    In addition to the number of shares the undersigned owns outright as indicated by the undersigned’s
answer to question B(1), as of MAY 1, 2022, the undersigned had or shared voting power or investment power, directly or indirectly, through a contract, arrangement, understanding,
relationship or otherwise (e.g., shares held in a trust for which you are a trustee, shares subject to a written voting or investment arrangement, shares held by a corporate benefit plan over which you exercise control), over the
following number of shares of the Company’s capital stock (none indicated by “0”):                     . 

 If the answer to this question B(2) was not “0,” please provide the following
information: 
  

	 	(i)	 Number of shares with sole voting power:
                     

  

	 	(ii)	 Number of shares with shared voting power, with whom shared, and the nature of the relationship and any
underlying voting trust agreement (including the duration of the agreement, the names and addresses of the voting trustees and a brief description of the voting rights and other powers of such trustees), investment arrangement or the like:

 If you wish to disclaim beneficial ownership of any of the shares described in question B.2 above for purposes
other than for use in the Registration Statement, please indicate the number and class of shares being disclaimed and the reason therefore: 

3.    As of JUNE 30, 2022, the undersigned has the
right to acquire                  shares of the Company’s Common Stock pursuant to outstanding stock options issued under the Company’s stock
option plans and                  shares of capital stock pursuant to the exercise of outstanding warrants.

 Exhibit 10.2 

REGISTRATION RIGHTS AGREEMENT 

This REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is made and entered into as of May 27, 2022 by and among RAPT
Therapeutics, Inc., a Delaware corporation (the “Company”), and the “Investors” named in that certain Securities Purchase Agreement by and among the Company and the Investors (the “Purchase Agreement”). Capitalized
terms used herein have the respective meanings ascribed thereto in the Purchase Agreement unless otherwise defined herein. 
 The parties
hereby agree as follows: 
 1.     Certain Definitions. 

As used in this Agreement, the following terms shall have the following meanings: 

“Effectiveness Deadline” means, with respect to the Registration Statement, the 120th calendar day following the Closing
Date; provided, however, that if the Effectiveness Deadline falls on a Saturday, Sunday or other day that the SEC is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the SEC is open for business.

 “Investors” means the Investors identified in the Purchase Agreement and any Affiliate or permitted transferee of any
Investor who is a subsequent holder of Registrable Securities. 
 “Prospectus” means (i) the prospectus included in
any Registration Statement, as amended or supplemented by any prospectus supplement, with respect to the terms of the offering of any portion of the Registrable Securities covered by such Registration Statement and by all other amendments and
supplements to the prospectus, including post-effective amendments and all material incorporated by reference in such prospectus, and (ii) any “free writing prospectus” as defined in Rule 405 under the 1933 Act. 

“Register,” “registered” and “registration” refer to a registration made by preparing and
filing a Registration Statement or similar document in compliance with the 1933 Act, and the declaration or ordering of effectiveness of such Registration Statement or document. 

“Registrable Securities” means (i) the Warrant Shares and (ii) any other securities issued or issuable with respect
to or in exchange for Registrable Securities, whether by merger, charter amendment or otherwise; provided, that a security shall cease to be a Registrable Security upon (A) sale pursuant to a Registration Statement or Rule 144 under the
1933 Act, or (B) such security becoming eligible for sale without restriction by the Investors pursuant to Rule 144. 

“Registration Statement” means any registration statement of the Company under the 1933 Act that covers the resale of any of
the Registrable Securities pursuant to the provisions of this Agreement, amendments and supplements to such Registration Statement, including post-effective amendments, all exhibits and all material incorporated by reference in such Registration
Statement. 
 “Required Investors” means the Investors holding a majority of the Registrable Securities outstanding from
time to time. 

 2.     Registration. 

(a)     Registration Statements. 

(i)    Promptly following the Closing Date but no later than 60 days
after the Closing Date (the “Filing Deadline”), the Company shall prepare and file with the Securities and Exchange Commission (the “SEC”) one Registration Statement covering the resale of all of the Registrable Securities.
Subject to any SEC comments, such Registration Statement shall include the plan of distribution attached hereto as Exhibit A. Such Registration Statement also shall cover, to the extent allowable under the 1933 Act and the
rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. Such Registration
Statement shall not include any shares of Common Stock or other securities for the account of any other holder without the prior written consent of the Required Investors. Such Registration Statement (and each amendment or supplement thereto, and
each request for acceleration of effectiveness thereof) shall be provided in accordance with Section 3(c) to the Investors prior to its filing or other submission. If a Registration Statement covering the Registrable Securities is not filed
with the SEC on or prior to the Filing Deadline, the Company will make pro rata payments to each Investor, as liquidated damages and not as a penalty, in an amount equal to 1% of the aggregate amount invested by such Investor for each 30-day period or pro rata for any portion thereof following the Filing Deadline for which no Registration Statement is filed with respect to the Registrable Securities. Such payments shall constitute the
Investors’ exclusive monetary remedy for such events, but shall not affect the right of the Investors to seek injunctive relief. Such payments shall be made to each Investor in cash no later than three Business Days after the end of each 30-day period (the “Payment Date”). Interest shall accrue at the rate of 1% per month on any such liquidated damages payments that shall not be paid by the Payment Date until such amount is paid in full.

 (ii)    The Registration Statement referred to in Section 2(a)(i) shall be on Form S-3. In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the
Registrable Securities on such other form as is available to the Company and (ii) so long as Registrable Securities remain outstanding, promptly following the date (the “Qualification Date”) upon which the Company becomes eligible to
use a registration statement on Form S-3 to register the Registrable Securities for resale, but in no event more than 60 days after the Qualification Date (the “Qualification Deadline”), the
Company shall file a registration statement on Form S-3 covering the Registrable Securities (or a post-effective amendment on Form S-3 to a registration statement on
Form S-1) (a “Shelf Registration Statement”); provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Shelf Registration Statement
covering the Registrable Securities has been declared effective by the SEC. 
 (b)     Expenses. The Company will
pay all reasonable expenses associated with the filing of any Registration Statement, including filing and printing fees, the Company’s counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale
under applicable state securities laws and listing fees, but excluding discounts, commissions and fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being
sold. 

  
 2 

 (c)     Effectiveness. 

(i)    The Company shall use commercially reasonable efforts to have the Registration Statement declared effective as soon
as practicable, but no later than the Effectiveness Deadline. The Company shall notify the Investors by e-mail as promptly as practicable, and in any event, within 48 hours, after any Registration
Statement is declared effective and shall simultaneously provide the Investors with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby. If (A) a Registration Statement
covering the Registrable Securities is not declared effective by the SEC prior to the earlier of (i) 10 Business Days after the SEC informs the Company that no review of such Registration Statement will be made or that the SEC has no further
comments on such Registration Statement or (ii) the Effectiveness Deadline, or (B) after a Registration Statement has been declared effective by the SEC, sales cannot be made pursuant to such Registration Statement for any reason
(including without limitation by reason of a stop order, or the Company’s failure to update such Registration Statement), but excluding any Allowed Delay (as defined below), then the Company will make pro rata payments to each Investor then
holding Registrable Securities, as liquidated damages and not as a penalty, in an amount equal to 1% of the aggregate amount invested by such Investor for each 30-day period or pro rata for any portion thereof
following the date by which such Registration Statement should have been effective (the “Blackout Period”). Such payments shall constitute the Investors’ exclusive monetary remedy for such events, but shall not affect the right of the
Investors to seek injunctive relief. The amounts payable as liquidated damages pursuant to this paragraph shall be paid monthly within three Business Days of the last day of each month following the commencement of the Blackout Period until the
termination of the Blackout Period (the “Blackout Period Payment Date”). Such payments shall be made to each Investor in cash. Interest shall accrue at the rate of 1% per month on any such liquidated damages payments that shall not be paid
by the Blackout Payment Date until such amount is paid in full. 
 (ii)    For not more than 30 consecutive days or for
a total of not more than 60 days in any 12 month period, the Company may suspend the use of any Prospectus included in any Registration Statement contemplated by this Section in the event that the Company determines in good faith that such
suspension is necessary to (A) delay the disclosure of material non-public information concerning the Company, the disclosure of which at the time is not, in the good faith opinion of the Company, in the
best interests of the Company or (B) amend or supplement the affected Registration Statement or the related Prospectus so that such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that the
Company shall promptly (a) notify each Investor in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor any material
non-public information giving rise to an Allowed Delay, (b) advise the Investors in writing to cease all sales under such Registration Statement until the end of the Allowed Delay and (c) use
commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable. 

  
 3 

 (d)    Rule 415; Cutback. If at any time the
SEC takes the position that the offering of some or all of the Registrable Securities in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the 1933 Act or requires any
Investor to be named as an “underwriter,” the Company shall use commercially reasonable efforts to persuade the SEC that the offering contemplated by such Registration Statement is a valid secondary offering and not an offering “by or
on behalf of the issuer” as defined in Rule 415 and that none of the Investors is an “underwriter.” The Investors shall have the right to select one legal counsel designated by the holders of a majority of the Registrable
Securities to review and oversee any registration or matters pursuant to this Section 2(d), including participation in any meetings or discussions with the SEC regarding the SEC’s position and to comment on any written submission made to
the SEC with respect thereto. No such written submission with respect to this matter shall be made to the SEC to which the Investors’ counsel reasonably objects. In the event that, despite the Company’s commercially reasonable efforts and
compliance with the terms of this Section 2(d), the SEC refuses to alter its position, the Company shall (i) remove from such Registration Statement such portion of the Registrable Securities (the “Cut Back Shares”) and/or
(ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC
Restrictions”); provided, however, that the Company shall not agree to name any Investor as an “underwriter” in such Registration Statement without the prior written consent of such Investor. Any
cut-back imposed on the Investors pursuant to this Section 2(d) shall be allocated among the Investors on a pro rata basis and shall be applied first to any of the Registrable Securities of such Investor
as such Investor shall designate, unless the SEC Restrictions otherwise require or provide or the Investors otherwise agree. No liquidated damages shall accrue as to any Cut Back Shares until such date as the Company is able to effect the
registration of such Cut Back Shares in accordance with any SEC Restrictions applicable to such Cut Back Shares (such date, the “Restriction Termination Date”). In furtherance of the foregoing, each Investor shall provide the Company with
prompt written notice of its sale of substantially all of the Registrable Securities under such Registration Statement such that the Company will be able to file one or more additional Registration Statements covering the Cut Back Shares. From and
after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this Section 2 (including the Company’s obligations with respect to the filing of a Registration Statement and its obligations to use
commercially reasonable efforts to have such Registration Statement declared effective within the time periods set forth herein and the liquidated damages provisions relating thereto) shall again be applicable to such Cut Back Shares; provided,
however, that (i) the Filing Deadline and/or the Qualification Deadline, as applicable, for such Registration Statement including such Cut Back Shares shall be 10 Business Days after such Restriction Termination Date, and (ii) the date by
which the Company is required to obtain effectiveness with respect to such Cut Back Shares shall be the 120th day immediately after the Restriction Termination Date. 

3.    Company Obligations. The Company will use commercially reasonable efforts to effect the registration of the
Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will, as expeditiously as possible: 

(a)    use commercially reasonable efforts to cause such Registration Statement to become effective and to remain
continuously effective for a period that will terminate upon 

  
 4 

 
the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, and (ii) the date on which all
Registrable Securities covered by such Registration Statement may be sold without restriction pursuant to Rule 144 (the “Effectiveness Period”) and advise the Investors promptly in writing when the Effectiveness Period has expired;

 (b)    prepare and file with the SEC such amendments and post-effective amendments to such Registration Statement and
the related Prospectus as may be necessary to keep such Registration Statement effective for the Effectiveness Period and to comply with the provisions of the 1933 Act and the 1934 Act with respect to the distribution of all of the Registrable
Securities covered thereby; 
 (c)    provide copies to and permit any counsel designated by the Investors to review
each Registration Statement and all amendments and supplements thereto no fewer than three days prior to their filing with the SEC and not file any document to which such counsel reasonably objects; 

(d)    furnish to each Investor whose Registrable Securities are included in any Registration Statement (i) promptly
after the same is prepared and filed with the SEC, if requested by the Investor, one copy of any Registration Statement and any amendment thereto, each preliminary prospectus and Prospectus and each amendment or supplement thereto, and each letter
written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion of any thereof which
contains information for which the Company has sought confidential treatment), and (ii) such number of copies of a Prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as each
Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor; 

(e)    use commercially reasonable efforts to (i) prevent the issuance of any stop order or other suspension of
effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order at the earliest practical moment; 

(f)    prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify
or cooperate with the Investors and their counsel in connection with the registration or qualification of such Registrable Securities for the offer and sale under the securities or blue sky laws of such jurisdictions requested by the Investors and
do any and all other commercially reasonable acts or things necessary or advisable to enable the distribution in such jurisdictions of the Registrable Securities covered by the Registration Statement; provided, however, that the Company shall not be
required in connection therewith or as a condition thereto to (i) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(f), (ii) subject itself to general taxation in any
jurisdiction where it would not otherwise be so subject but for this Section 3(f), or (iii) file a general consent to service of process in any such jurisdiction; 

(g)    use commercially reasonable efforts to cause all Registrable Securities covered by a Registration Statement to be
listed on each securities exchange, interdealer quotation system or other market on which similar securities issued by the Company are then listed; 

  
 5 

 (h)    promptly notify the Investors, at any time prior to the end of
the Effectiveness Period, upon discovery that, or upon the happening of any event as a result of which, the Prospectus includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then existing, and promptly prepare, file with the SEC and furnish to such holder a supplement to or an amendment of such Prospectus as may be necessary so that such Prospectus
shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; 

(i)    otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC under
the 1933 Act and the 1934 Act, including, without limitation, Rule 172 under the 1933 Act, file any final Prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under the 1933 Act, promptly inform the
Investors in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Investors are required to deliver a Prospectus in connection with any
disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder, and make available to its security holders, as soon as reasonably practicable,
but not later than the Availability Date (as defined below), an earnings statement covering a period of at least 12 months, beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the provisions
of Section 11(a) of the 1933 Act, including Rule 158 promulgated thereunder (for the purpose of this subsection 3(i), “Availability Date” means the 45th day following the end of the fourth fiscal quarter that includes the
effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the 90th day after the end of such fourth fiscal quarter); and 

(j)    with a view to making available to the Investors the benefits of Rule 144 (or its successor rule) and any
other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock to the public without registration, the Company covenants and agrees to: (i) make and keep public information available, as those terms
are understood and defined in Rule 144, until the earlier of (A) six months after such date as all of the Registrable Securities may be sold without restriction by the holders thereof pursuant to Rule 144 or any other rule of similar
effect or (B) such date as all of the Registrable Securities shall have been resold; (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the 1934 Act; and (iii) furnish to each
Investor upon request, as long as such Investor owns any Registrable Securities, (A) a written statement by the Company that it has complied with the reporting requirements of the 1934 Act, (B) a copy of the Company’s most recent
Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be reasonably requested in order to avail such Investor of any
rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration. 

  
 6 

 4.    Due Diligence Review; Information. If any Investor is
required under applicable securities laws to be described in a Registration Statement as an “underwriter,” the Company shall, upon reasonable prior notice, make available, during normal business hours, for inspection and review by the
Investors, advisors to and representatives of the Investors (who may or may not be affiliated with the Investors and who are reasonably acceptable to the Company) (collectively, the “Inspectors”), all pertinent financial and other
records, and all other corporate documents and properties of the Company (collectively, the “Records”) as may be reasonably necessary for the purpose of such review, and cause the Company’s officers, directors and employees,
within a reasonable time period, to supply all such information reasonably requested by the Inspectors (including, without limitation, in response to all questions and other inquiries reasonably made or submitted by any of them), prior to and from
time to time after the filing and effectiveness of such Registration Statement for the sole purpose of enabling such Investor and its accountants and attorneys to conduct such due diligence solely for the purpose of establishing a due diligence
defense to underwriter liability under the 1933 Act; provided, however, that each Inspector shall agree to hold in strict confidence and shall not make any disclosure (except to such Investor) or use of any Record or other information
which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration
Statement or is otherwise required under the 1933 Act, (b) the release of such Records is ordered pursuant to a final, non-appealable subpoena or order from a court or government body of competent
jurisdiction, or (c) the information in such Records has been made generally available to the public other than by disclosure in violation of this or any other Transaction Document. 

Notwithstanding the foregoing, the Company shall not disclose material nonpublic information to the Investors, or to advisors to or
representatives of the Investors, unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Investors, such advisors and representatives with the opportunity to
accept or refuse to accept such material nonpublic information for review and any Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto. 

5.     Obligations of the Investors. 

(a)    Each Investor shall furnish in writing to the Company such information regarding itself, the Registrable Securities
held by it and the intended method of disposition of the Registrable Securities held by it, as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. At least five Business Days prior to the first anticipated filing date of any Registration Statement, the Company shall notify each Investor of the information the Company requires from such
Investor if such Investor elects to have any of the Registrable Securities included in such Registration Statement. An Investor shall provide such information to the Company at least two Business Days prior to the first anticipated filing date of
such Registration Statement if such Investor elects to have any of the Registrable Securities included in such Registration Statement. 

  
 7 

 (b)    Each Investor, by its acceptance of the Registrable Securities,
agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Investor has notified the Company in writing of its election to exclude all
of its Registrable Securities from such Registration Statement. 
 (c)    Each Investor agrees that, upon receipt of any
notice from the Company of either (i) the commencement of an Allowed Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(h) hereof, such Investor will immediately discontinue disposition of
Registrable Securities pursuant to any Registration Statement covering such Registrable Securities, until the Investor is advised by the Company that such dispositions may again be made. 

(d)    Each Investor covenants and agrees that it will comply with the prospectus delivery requirements of the 1933 Act as
applicable to it or an exemption therefrom in connection with sales of Registrable Securities pursuant to any Registration Statement. 

6.     Indemnification. 

(a)    Indemnification by the Company. The Company will indemnify and hold harmless each Investor and its officers,
directors, members, employees and agents, successors and assigns, and each other person, if any, who controls such Investor within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they may
become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: any untrue statement or alleged untrue statement or omission or alleged
omission of any material fact contained in any Registration Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof and will reimburse such Investor, and each such officer, director or member and each such
controlling person for any legal or other documented, out-of-pocket expenses reasonably incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon (i) an untrue statement
or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Investor or any such controlling person in writing specifically for use in such Registration Statement or Prospectus, (ii) the
use by an Investor of an outdated or defective Prospectus after the Company has notified such Investor in writing that such Prospectus is outdated or defective; (iii) an Investor’s failure to send or give a copy of the Prospectus or
supplement (as then amended or supplemented), if required (and not exempted) to the Persons asserting an untrue statement or omission or alleged untrue statement or omission at or prior to the written confirmation of the sale of Registrable
Securities; or (iv) an Investor’s bad faith, gross negligence, recklessness, fraud or willful misconduct. 

(b)    Indemnification by the Investors. Each Investor agrees, severally but not jointly, to indemnify and hold
harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and
expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or any 

  
 8 

 
omission of a material fact required to be stated in any Registration Statement or Prospectus or preliminary Prospectus or amendment or supplement thereto or necessary to make the statements
therein not misleading, to the extent, but only to the extent that such untrue statement of material fact or omission is contained in any information furnished in writing by such Investor to the Company specifically for inclusion in such
Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds received by such Investor upon the sale of the Registrable Securities
included in such Registration Statement giving rise to such indemnification obligation. 
 (c)    Conduct of
Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying
party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense
of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed in writing to pay such fees or expenses, (b) the indemnifying party shall have failed to assume
the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the
indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not
have the right to assume the defense of such claim on behalf of such person); and provided, further that the failure of any indemnified party to give written notice as provided herein shall not relieve the indemnifying party of its obligations
hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any
proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to
entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. 

(d)    Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and
(b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such
loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent
misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the aggregate liability a holder of Registrable
Securities under this Section 6(c) and Section 6(b) be greater in amount than the dollar amount of the net proceeds received by it upon the sale of the Registrable Securities giving rise to such contribution obligation. The amount paid or
payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Section 6(a), 6(b) and 6(c), any legal or 

  
 9 

 
other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties agree that it would not be just and equitable if contribution
pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 6(d). 

7.     Miscellaneous. 

(a)    Effective Date. This Agreement shall be effective as of the Closing Date, and if the Closing Date has not
occurred on or prior to the fifth trading day following the date of the Purchase Agreement, unless otherwise mutually agreed, then this Agreement shall be null and void. 

(b)    Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the
Required Investors. The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company shall have obtained the written consent to such amendment, action or omission to act, of the
Required Investors. 
 (c)    Notices. All notices and other communications provided for or permitted hereunder
shall be made as set forth in Section 9.4 of the Purchase Agreement. 
 (d)    Assignments and Transfers by

hereunder, the term “Company” shall be deemed to refer to such Person and the term “Registrable Securities” shall be deemed to include the securities received by the Investors in connection with such transaction unless such
securities are otherwise freely tradable by the Investors after giving effect to such transaction.

 Exhibit A 

Plan of Distribution 
 We are registering
the shares of common stock issuable on the exercise of previously issued pre-funded warrants to permit the resale of these shares of common stock by the holders of the common stock from time to time after the
date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock, except
that, if the shares of common stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. 

The selling stockholders may sell all or a portion of the shares of our common stock beneficially owned by them and offered hereby from time to time directly
or through one or more underwriters, broker-dealers or agents. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale,
or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, 
  

	 	•	 	 on any national securities exchange or quotation service on which the securities may be listed or quoted at the
time of sale; 

  

	 	•	 	 in the over-the-counter market;

  

	 	•	 	 in transactions otherwise than on these exchanges or systems or in the over-the-counter market; 

  

	 	•	 	 through the writing of options, whether such options are listed on an options exchange or otherwise;

  

	 	•	 	 ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

  

	 	•	 	 block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a
portion of the block as principal to facilitate the transaction; 

  

	 	•	 	 purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

 

	 	•	 	 distributions to members, partners, stockholders or other equityholders of the selling stockholders;

  

	 	•	 	 an exchange distribution in accordance with the rules of the applicable exchange; 

 

	 	•	 	 privately negotiated transactions; 

 

	 	•	 	 short sales; 

	 	•	 	 sales pursuant to Rule 144 of the Securities Act; 

 

	 	•	 	 broker-dealers may agree with the selling stockholder to sell a specified number of such shares at a stipulated
price per share; 

  

	 	•	 	 a combination of any such methods of sale; and 

 

	 	•	 	 any other method permitted pursuant to applicable law. 

If the selling stockholders effect such transactions by selling shares of our common stock to or through underwriters, broker-dealers or agents, such
underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of our common stock for whom they may act as agent or to
whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares
of our common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of our common stock in the course of hedging in positions they assume. The
selling stockholders may also sell shares of our common stock short and deliver shares of our common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling
stockholders may also loan or pledge shares of our common stock to broker-dealers that in turn may sell such shares. 
 The selling stockholders may pledge
or grant a security interest in some or all of the shares of our common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time
to time pursuant to this prospectus or other applicable provisions of the Securities Act, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this
prospectus. The selling stockholders also may transfer and donate the shares of our common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for
purposes of this prospectus. 
 The selling stockholders and any broker-dealer participating in the distribution of the shares of our common stock may be
deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the
Securities Act. At the time a particular offering of the shares of our common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of our common stock being offered and the
terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed
or paid to broker-dealers. 

 Under the securities laws of some states, the shares of our common stock may be sold in such states only
through registered or licensed brokers or dealers. In addition, in some states the shares of our common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or
qualification is available and is complied with. 
 There can be no assurance that any selling stockholder will sell any or all of the shares of our common
stock registered pursuant to the registration statement, of which this prospectus forms a part. 
 The selling stockholders and any other person
participating in such distribution will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and
sales of any of the shares of our common stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of our common stock to engage in
market-making activities with respect to the shares of our common stock. All of the foregoing may affect the marketability of the shares of our common stock and the ability of any person or entity to engage in market-making activities with respect
to the shares of our common stock. 
 We will pay all expenses of the registration of the shares of our common stock pursuant to the registration statement
of which this prospectus forms a part, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that the selling stockholders will pay all underwriting discounts
and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling
stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus or we may be entitled to
contribution. 
 Once sold under the registration statement of which this prospectus forms a part, the shares of our common stock will be freely tradable in
the hands of persons other than our affiliates.
