Securities Purchase Agreement, dated October 1, 2020, by and among Arcutis Biotherapeutics, Inc. and the purchasers named therein

This Securities Purchase Agreement (“Agreement”) is made as of October 1, 2020 (the “Effective Date”), by and among Arcutis Biotherapeutics, Inc., a Delaware corporation (the “Company”), and each of those persons and entities, severally and not jointly, listed as a Purchaser on the Schedule of Purchasers attached as Exhibit A hereto (the “Schedule of Purchasers”).

The persons and entities listed as Purchasers on the Schedule of Purchasers are hereinafter collectively referred to herein as “Purchasers” and each individually as a “Purchaser.”

In consideration of the mutual covenants contained in this Agreement, and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Company and each Purchaser (severally and not jointly) hereby agree as follows:

The Company has authorized the sale and issuance of $35.0 million of shares of its Common Stock, par value $0.0001 per share (the “Common Stock”), on the terms and subject to the conditions set forth in this Agreement.

2.1Sale of Shares. At the Closing (as defined in Section 3), the Company will sell to each Purchaser, and each Purchaser will, severally but not jointly, purchase from the Company, the Shares (as defined below) at a price per share equal to the per share public offering price (before underwriting discounts and expenses) in the concurrent public offering (the “Public Offering Price”). “Shares” shall mean the number of shares of Common Stock equal to the purchase amount set forth opposite such Purchaser’s name on the Schedule of Purchasers divided by the Public Offering Price. “Concurrent Public Offering” shall mean the issuance and sale of shares of Common Stock by the Company, pursuant to an underwriting agreement (the “Underwriting Agreement”) to be entered into by and among the Company and certain underwriters (the “Underwriters”) in connection with the Company’s public offering pursuant to the Company’s registration statement on Form S-1.

2.2Separate Agreement. Each Purchaser shall severally, and not jointly, be liable for only the purchase of the Shares that relate to such Purchaser’s purchase amount on the Schedule of Purchasers. The Company’s agreement with each of the Purchasers is a separate agreement, and the sale of Shares to each of the Purchasers is a separate sale. The obligations of

each Purchaser hereunder are expressly not conditioned on the purchase by any or all of the other Purchasers of the Shares such other Purchasers have agreed to purchase.

3.1Closing. The closing of the purchase and sale of the Shares pursuant to this Agreement shall take place at the location and at the time immediately subsequent to the closing of the Concurrent Public Offering, or on such other date and place as may be agreed to by the Company and the Purchasers (such time and place are designated as the “Closing”).

3.2Issuance of the Shares at the Closing. At the Closing, each Purchaser shall make payment of the purchase price of the Shares by wire transfer in immediately available funds to the account specified by the Company, and the Company shall promptly issue or deliver to each Purchaser evidence of a book entry position evidencing the Shares purchased by such Purchaser hereunder, registered in the name of such Purchaser, or in such nominee name(s) as designated by such Purchaser, which Shares shall be uncertificated. The name(s) in which the Shares are to be issued to each Purchaser are set forth in the Schedule of Purchasers.

3.3Delivery of the Registration Rights Agreement. At or before the Closing, the Company and each Purchaser shall execute and deliver the Registration Rights Agreement in the form attached hereto as Appendix I (the “Registration Rights Agreement”), with respect to the registration of the Shares under the Securities Act of 1933, as amended (the “Securities Act”).

The Company hereby represents and warrants to, as of the date hereof and as of the Closing, and covenants with, the Purchasers as follows:

4.1Organization and Standing. The Company has been (a) duly organized and is validly existing and in good standing under the laws of its jurisdiction of organization, with power and authority (corporate and other) to own and/or lease its properties and conduct its business as presently conducted, and (b) duly qualified as a foreign corporation for the transaction of business and is in good standing (where such concept exists) under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, except, in the case of this clause (b), where the failure to be so qualified or in good standing would not, individually or in the aggregate, have a Material Adverse Effect. As used in this Agreement, “Material Adverse Effect” shall mean any material adverse change or effect, or any development involving a prospective material adverse change or effect, in or affecting (i) the business, properties, general affairs, management, financial position, stockholders’ equity, results of operations or prospects of the Company, or (ii) the ability of the Company to perform its obligations under this Agreement, including the issuance and sale of the Shares, or to consummate the transactions contemplated by the Concurrent Public Offering.

4.2Corporate Power; Authorization. The Company has all requisite corporate power and authority, and has taken all requisite corporate action, to execute and deliver this Agreement and the Registration Rights Agreement (collectively, the “Transaction Documents”), sell and issue the Shares and carry out and perform all of its obligations under the Transaction

Documents. Each Transaction Document constitutes the legal, valid and binding obligation of the Company, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally, (ii) as limited by equitable principles generally, including any specific performance and (iii) with respect to the Registration Rights Agreement, as rights to indemnity or contribution may be limited by state or federal laws or public policy underlying such laws.

4.3Issuance and Delivery of the Shares. The Shares have been duly authorized and, when issued and paid for in compliance with the provisions of this Agreement, will be validly issued, fully paid and nonassessable and free of any security interest, lien, pledge, claim, charge, escrow, encumbrance, right of first offer, right of first refusal, preemptive right, mortgage, indenture, security agreement or other restriction other than restrictions on transfer under the Transaction Documents and applicable state and federal securities laws.

4.4No Defaults. The issue and sale of the Shares and the compliance by the Company with the Transaction Documents and the consummation of the transactions contemplated by the Transaction Documents will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, (A) any indenture, mortgage, deed of trust, loan agreement, license, lease or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject, (B) the certificate of incorporation or by-laws (or other applicable organizational document) of the Company, or (C) any statute or any judgment, order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its properties, except, in the case of clauses (A) and (C), for such defaults, breaches, or violations that would not, individually or in the aggregate, have a Material Adverse Effect.

4.5No Violation. The Company is not (i) in violation of its certificate of incorporation or by-laws (or other applicable organizational document), (ii) in violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its properties or assets, or (iii) in default, and no event has occurred that, with notice or lapse of time or both, would constitute such a default, in the performance or observance of any obligation, agreement, term, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, license, lease or other agreement or instrument to which it is a party or by which it or any of its properties or assets may be bound, except, in the case of the foregoing clauses (ii) and (iii), for such violations or defaults as would not, individually or in the aggregate, have a Material Adverse Effect.

4.6Description of Capital Stock. The statements set forth in the Registration Statement under the caption “Description of Capital Stock”, insofar as they purport to constitute a summary of the terms of the Company’s capital stock, are accurate, complete and fair in all material respects.

4.7Registration Statement. The Company’s registration statement on Form S-1, filed in connection with the Concurrent Public Offering (the “Registration Statement”), and any amendment thereto, including any information deemed to be included therein pursuant to the

rules and regulations of the United States Securities and Exchange Commission (the “SEC”) promulgated under the Securities Act, complied (or, in the case of amendments filed after the date of this Agreement, will comply) as of its filing date in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder, and did not (or, in the case of amendments filed after the date hereof, will not) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. As of the date it is declared effective by the SEC, the Registration Statement, as so amended, and any related registration statements, will comply in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder, and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. Any preliminary prospectus included in the Registration Statement or any amendment thereto, any free writing prospectus related to the Registration Statement and any final prospectus related to the Registration Statement filed pursuant to Rule 424 promulgated under the Securities Act, in each case as of its date, will comply in all material respects with the requirements of the Securities Act and the rules and regulations promulgated thereunder, and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

4.8Brokers or Finders. The Company has not engaged any brokers, finders or agents such that the Purchaser will incur, directly or indirectly, as a result of any action taken by the Company, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Agreement.

4.9Private Placement. Assuming the accuracy of the representations made by each Purchaser in Section 5, the offer and issuance by the Company of the Shares is exempt from registration under the Securities Act.

Each Purchaser, severally and not jointly, hereby represents and warrants to, as of the date hereof and as of the Closing, and covenants with, the Company that:

5.1Organization; Corporate Power; Authorization. Such Purchaser is a validly existing corporation, limited partnership, limited liability company, trust, pension plan, or government plan and has all requisite corporate, partnership, limited liability company or other requisite organizational power and authority to enter into and consummate the transactions contemplated by the Transaction Documents and to carry out its obligations hereunder and thereunder, and to invest in the Shares pursuant to this Agreement.

5.2No Public Offering. Such Purchaser acknowledges its understanding and agreement that the Shares are being offered in a transaction not involving any public offering within the Unites States within the meaning of the Securities Act, or a distribution in violation of the Securities Act or any jurisdiction, that the Shares have not been registered under the Securities

Act or the securities laws of any jurisdiction and, unless so registered, may not be sold except as exempt from registration under the Securities Act.

5.3No Registration; Private Placement. Such Purchaser acknowledges its understanding that the transactions contemplated by the Transaction Documents and sale of the Shares pursuant to this Agreement are intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) of the Securities Act and that the Company is relying on such Purchaser’s representations and warranties in connection with this exemption. In furtherance thereof, such Purchaser represents and warrants to the Company and its affiliates as follows:

5.4Restricted Securities. Such Purchaser will not sell or otherwise transfer any Shares without either registration under the Securities Act or an exemption therefrom, and fully understands and agrees that such Purchaser must bear the economic risk of its purchase because, among other reasons, the Shares have not been registered under the Securities Act or under the securities laws of any state and, therefore, cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and under the applicable securities laws of such states, or an exemption from such registration is available. In particular, such Purchaser is aware that the Shares are “restricted securities,” as such term is defined in Rule 144 promulgated under the Securities Act (“Rule 144”), and they may not be sold pursuant to Rule 144 unless all of the conditions of Rule 144 are met. Such Purchaser understands that the Company or its transfer agent may establish procedures for approval of transfers,

including transfers sought to be permitted under Rule 144, which may result in delays in desired sales or transfers by Purchaser.

5.5Legends. Such Purchaser understands and agrees that the Shares may bear one or more of the following legends:

5.6Brokers or Finders. Such Purchaser has not engaged any brokers, finders or agents such that the Company will incur, directly or indirectly, as a result of any action taken by such Purchaser, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Agreement.

5.7HSR Act. Such Purchaser (including any person controlling, controlled by, or under common control with such Purchaser, as the term “control” is defined pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and its implementing regulations (the “HSR Act”)) in connection with the consummation of the transactions contemplated by this Agreement will not be required to and will not complete a filing with the U.S. government pursuant to the HSR Act.

5.8Short Sales. Other than consummating the transactions contemplated hereunder, such Purchaser has not, nor has any person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any purchases or sales, including all “short sales” as defined in Rule 200 of Regulation SHO under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (but shall not be deemed to include the location and/or reservation of borrowable shares of Common Stock) (“Short Sales”), of the securities of the Company during the period commencing as of the time that such Purchaser was first contacted by the Company or any other person regarding the transactions contemplated hereby and ending immediately prior to the Effective Date. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’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 Shares covered by this Agreement. Other than to other persons party to this Agreement and to its representatives and advisors, such Purchaser 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.

5.9Address. Such Purchaser’s residence (if an individual) or offices in which its investment decision with respect to the Shares was made (if an entity) are located at the address immediately below such Purchaser’s name on the Schedule of Purchasers.

The Company’s obligation to complete the sale and issuance of the Shares and deliver Shares to each Purchaser at the Closing shall be subject to the following conditions to the extent not waived by the Company:

6.1Receipt of Payment. The Company shall have received payment, by wire transfer of immediately available funds, in the full amount of the purchase price for the Shares being purchased by such Purchaser at the Closing.

6.2Representations and Warranties. The representations and warranties made by the Purchasers in Section 5 hereof shall be true and correct in all material respects when made, and shall be true and correct in all material respects on the Closing with the same force and effect as if they had been made on and as of said date. The Purchasers shall have performed in all material respects all obligations and covenants herein required to be performed by them on or prior to the Closing.

6.3Receipt of Executed Documents. Such Purchaser shall have executed and delivered to the Company the Registration Rights Agreement.

6.4Concurrent Public Offering. The Underwriting Agreement shall have been executed and the Underwriters shall have purchased, immediately prior to the purchase of the Shares by each Purchaser hereunder, the shares in the Concurrent Public Offering.

Each Purchaser’s obligation to accept delivery of the Shares and to pay for the Shares shall be subject to the following conditions to the extent not waived by such Purchaser:

7.1Representations and Warranties. The representations and warranties made by the Company in Section 4 hereof shall be true and correct in all material respects as of, and as if made on, the date of this Agreement and as of the Closing, except (i) for those representations and warranties which are qualified as to materiality, in which case such representations and warranties shall be true and correct in all respects and (ii) to the extent any such representation or warranty

expressly speaks as of an earlier date, in which case such representation or warranty shall be true and correct as of such earlier date.

7.2Performance. The Company shall have performed in all material respects all obligations and covenants herein required to be performed by it on or prior to the Closing.

7.3Receipt of Executed Registration Rights Agreement. The Company shall have executed and delivered to the Purchasers the Registration Rights Agreement.

7.4Legal Opinion. The Purchasers shall have received an opinion of Latham & Watkins LLP, special counsel to the Company, dated as of the Closing, in form and substance reasonably acceptable to the Purchasers.

7.5Good Standing. The Company is validly existing as a corporation in good standing under the laws of Delaware.

7.6Nasdaq Filing. The Company shall have filed with NASDAQ a Notification Form: Listing of Additional Shares for the listing of the Shares.

7.7Judgments. No judgment, writ, order, injunction, award or decree of or by any court, or judge, justice or magistrate, including any bankruptcy court or judge, or any order of or by any governmental authority, shall have been issued, and no action or proceeding shall have been instituted by any governmental authority, enjoining or preventing the consummation of the transactions contemplated hereby.

7.8Stop Orders. No stop order or suspension of trading shall have been imposed by the NASDAQ Global Market, the SEC or any other governmental regulatory body with respect to public trading in the Common Stock (any such order or suspension, a “Suspension”).

7.9Concurrent Public Offering. The Underwriting Agreement shall have been executed and the Underwriters shall have purchased, immediately prior to the purchase of the Shares by each Purchaser hereunder, the shares in the Concurrent Public Offering.

8.1This Agreement may be terminated, on a Purchaser-by-Purchaser basis, (a) upon the mutual written consent of the Company and such Purchaser; (b) upon withdrawal by the Company of the Registration Statement; or (c) on October 31, 2020 if the Closing has not occurred.

9.1Short Sales and Confidentiality After the Date Hereof. Each Purchaser 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. Except (x) as required by applicable law or the listing rules of any applicable national or regional securities exchange, (y) as required to be disclosed in filings or other submissions to any court, regulatory body, administrative agency, governmental

body, arbitrator or other legal authority having jurisdiction over a party hereto made to obtain necessary consents, approvals or filings, or (z) as provided by the terms and provisions of the existing confidentiality and non-use obligations of the parties hereto, each Purchaser covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company or required to be publicly disclosed pursuant to Section 9.2, such Purchaser will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction) (such obligations, the “Confidentiality Obligations”). Each Purchaser 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 Securities Act, as set forth in Item 239.10 of the Securities Act Rules Compliance and Disclosure Interpretations compiled by the Office of Chief Counsel, Division of Corporation Finance.

9.2Securities Laws Disclosure; Publicity. By the fourth trading day immediately following the execution of this Agreement, the Company will file a Current Report on Form 8-K (the “8-K”) with the SEC describing the material terms of the Transaction Documents (and including as exhibits to such Current Report on Form 8-K the agreements required to be filed in connection therewith). Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any public filing with the SEC or any regulatory agency or NASDAQ, without the prior written consent of such Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed, except: (a) as required by federal securities law in connection with (i) any registration statement contemplated by the Registration Rights Agreement and (ii) the filing of final Transaction Documents with the SEC; (b) the filing of a Form D with the SEC under the Securities Act (to the extent required by such filing) and (c) to the extent such disclosure is required by law or NASDAQ regulations, in which case the Company shall provide the Purchaser with prior notice of such disclosure permitted under this clause (c). As of the time of the filing of the 8-K, no Purchaser shall be in possession of any material, non-public information received from the Company, any subsidiary of the Company or any of their respective officers, directors, employees or agents, pursuant to the transactions contemplated by this Agreement that is not disclosed in the 8-K, press release or other disclosure by the Company that complies with the requirements of Regulation FD. 

9.3Confirmation of Securities Holdings. Upon request of a Purchaser, as long as such Purchaser is a record holder of the Shares, the Company will use commercially reasonable efforts to cause the transfer agent of the Shares to provide confirmation of such Purchaser’s Common Stock holdings.

10.1Indemnification by the Company. The Company agrees to indemnify and hold harmless each of the Purchasers, the officers, directors, partners, members, and employees of each Purchaser, each Person who controls any such Purchasers (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members and employees of each such controlling Person (each, an “Indemnified Party”), against any losses, claims, damages, liabilities or expenses, joint or several, to which such Indemnified

Party may become subject under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based in whole or in part on the inaccuracy in the representations and warranties of the Company contained in this Agreement or the failure of the Company to perform its obligations hereunder, and will reimburse each Indemnified Party for legal and other expenses reasonably incurred as such expenses are reasonably incurred by such Indemnified Party in connection with investigating, defending, settling, compromising or paying such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) the failure of such Indemnified Party to comply with the covenants and agreements contained in Sections 5 and 9.1 above respecting sale of the Shares, or (ii) the inaccuracy of any representations made by such Indemnified Party herein.

All notices, requests, consents and other communications hereunder shall be in writing, shall be sent by confirmed electronic mail, or mailed by first-class registered or certified airmail, or nationally recognized overnight express courier, postage prepaid, and shall be deemed given when so sent in the case of electronic mail transmission, or when so received in the case of mail or courier, and addressed as follows:

or to such other person at such other place as the Company shall designate to the Purchasers in writing; and

if to the Purchasers, at the address as set forth at the end of this Agreement, or at such other address or addresses as may have been furnished to the Company in writing.

12.1Waivers and Amendments. Neither this Agreement nor any provision hereof may be changed, waived, discharged, terminated, modified or amended with respect to the Company and a Purchaser only with the written consent of the Company and such Purchaser.

12.2Headings. The headings of the various sections of this Agreement have been inserted for convenience of reference only and shall not be deemed to be part of this Agreement.

12.3Severability. In case any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

12.4Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein and no action taken by any Purchaser pursuant hereto, shall be deemed to constitute the Purchaser as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group, or are deemed affiliates (as such term is defined under the Exchange Act) with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

12.5Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of California, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of Los Angeles. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of Los Angeles for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.

12.6Counterparts. This Agreement may be executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other parties. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile of “.pdf” signature were the original thereof.

12.7Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto.

12.8Entire Agreement. This Agreement and other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and thereof.

12.9Payment of Fees and Expenses. Each of the Company and the Purchasers shall bear its own expenses and legal fees incurred on its behalf with respect to this Agreement and the transactions contemplated hereby. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorney’s fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled.

12.10Survival. The representations, warranties, covenants and agreements made in this Agreement shall survive any investigation made by the Company or the Purchasers and the Closing.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized representatives as of the day and year first above written.

All expenses incident to the Company’s performance of or compliance with this Agreement (excluding any underwriting discounts and selling commissions, which shall be borne solely by the Purchaser) shall be paid by the Company, including (i) all registration and filing fees, and any other fees and expenses associated with filings required to be made with the SEC or FINRA, (ii) all fees and expenses in connection with compliance with any securities or “Blue Sky” laws, (iii) all printing, duplicating, word processing, messenger, telephone, facsimile and delivery expenses (including expenses of printing certificates for the Registrable Securities in a form eligible for deposit with The Depository Trust Company and of printing prospectuses), (iv) all fees and disbursements of counsel for the Company and of all independent certified public accountants or independent auditors of the Company and any subsidiaries of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance), (v) Securities Act liability insurance or similar insurance if the Company so desires, (vi) all fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange or quotation of the Registrable Securities on any inter-dealer quotation system, (vii) all reasonable fees and expenses of any other Persons retained by the Company in connection with any Registration Statement or sale, and (viii) all of the Company’s internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties) and (viii) one legal counsel selected by the Purchasers holding a majority of the Registrable Securities. To the extent that underwriting discounts and selling commissions are incurred in connection with the sale of Registrable Securities in an Underwritten Public Offering hereunder, such underwriting discounts and selling commissions shall be borne solely by each Purchaser, as applicable. Except as set forth in clause (viii) of the first sentence of this Section 2(b), the Company shall not be responsible for legal fees,

broker or similar commissions or any other costs incurred by any Purchaser in connection with the performance of its rights and obligations under this Agreement.

(c)Effectiveness.

(i)The Company shall use reasonable best efforts to have any Registration Statement declared effective as soon as practicable after the filing. The Company shall respond promptly to any and all comments made by the staff of the SEC on any Registration Statement, and shall submit to the SEC, within two (2) business days after the Company learns that no review of the Registration Statement will be made by the staff of the SEC or that the staff of the SEC has no further comments on such Registration Statement, as the case may be, a request for acceleration of the effectiveness of such Registration Statement to a time and date not later than two (2) business days after the submission of such request. The Company shall notify each Purchaser by facsimile or e-mail as promptly as practicable, and in any event, within twenty-four (24) hours, after any such Registration Statement is declared effective and shall, upon request, provide each Purchaser with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby.

(ii)If, with respect to any Registration Statement covering the Registrable Securities:

(A) such Registration Statement covering the Registrable Securities is not filed with the SEC on or prior to the Filing Deadline (a “Filing Failure”),

(B) such Registration Statement covering the Registrable Securities is not declared effective (an “Effectiveness Failure”) by the SEC prior to earlier of: (x) seven (7) 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, (y) the 175th calendar day following the Closing, or (z) in the event of a “review” by the SEC, the 205th calendar day following the Closing (as applicable, the “Effectiveness Deadline”), or

(C) 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) or, if the Registration Statement is on Form S-1, for a period of twenty (20) days following the date on which the Company files a post-effective amendment to incorporate the Company’s Annual Report on Form 10-K (a “Maintenance Failure”),

then the Company will make pro rata payments to each Purchaser then holding Registrable Securities, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount paid pursuant to the Purchase Agreement by such Purchaser for such Registrable Securities then held by such Purchaser on each of the following dates: on the initial date of the Filing Failure, Effectiveness Failure or Maintenance Failure, as applicable, and on every thirtieth (30^th) day thereafter (pro rated for periods less than thirty (30) days) (the “Blackout Period”). Such payments shall constitute the Purchaser’s exclusive monetary remedy for such events, but shall not affect the right of the Purchaser to seek injunctive relief. The amounts payable as liquidated damages pursuant to this paragraph shall be paid no later than five (5) Business Days after each such 30-day period following the commencement of the Blackout Period until the termination of the Blackout Period (the “Blackout Payment Date”). Such

payments shall be made to each Purchaser 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.

(iii)Notwithstanding anything to the contrary contained herein, the Company may, upon written notice to any holder of Registrable Securities included in a Registration Statement, suspend the use of any Registration Statement, including any Prospectus that forms a part of a Registration Statement, if the Company (X) determines that it would be required to make disclosure of material information in the Registration Statement that the Company has a bona fide business purpose for preserving as confidential, (Y) determines it must amend or supplement the 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 or (Z) has experienced or is experiencing some other material non-public event, including a pending transaction involving the Company, the disclosure of which at such time, in the good faith judgment of the Company, would adversely affect the Company; provided, however, in no event shall holders of Registrable Securities be suspended from selling Registrable Securities pursuant to the Registration Statement for a period that exceeds 30 consecutive Trading Days or 60 total Trading Days in any 360-day period (any such suspension contemplated by this Section 2(c)(iii), an “Allowed Delay”). Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to holders whose Registrable Securities are included in the Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated hereby.

(d)If 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 another appropriate form and (ii) undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC.

(e)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 Securities Act, the Company shall (i) remove from the 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 Purchaser as an “underwriter” in such Registration Statement without the prior written consent of such Purchaser. 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”). 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 reasonable best 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 the Filing Deadline for the Registration

Statement including such Cut Back Shares shall be (20) business days after such Restriction Termination Date and the Effectiveness Deadline for the Registration Statement including such Cut Back Shares shall be sixty (60) business Days after such Restriction Termination Date.

(f)Other Limitations. Notwithstanding any other provision herein or in the Purchase Agreement, (i) the Filing Deadline and each Effectiveness Deadline for a Registration Statement shall be extended and any Maintenance Failure shall be automatically waived by no action of a Purchaser, in each case, without default by or liquidated damages payable by the Company hereunder to such Purchaser in the event that the Company’s failure to make such filing or obtain such effectiveness or a Maintenance Failure results solely and directly from the failure of such Purchaser to timely provide the Company with information requested by the Company in writing as being necessary to complete a Registration Statement in accordance with the requirements of the 1933 Act (in which case any such deadline would be extended, and a Maintenance Failure waived, with respect to all Registrable Securities during the period from the date of such written request until such time as such Purchaser provides such requested information) and (ii) in no event shall the aggregate amount of liquidated damages (or interest thereon) paid to any Purchaser hereunder exceed, in the aggregate, 5% of the aggregate purchase price of the Shares purchased by such Purchaser under the Purchase Agreement.

The Company will use reasonable best efforts to effect the registration of the Registrable Securities of each Purchaser in accordance with the terms hereof, and pursuant thereto the Company will, as expeditiously as possible:

(a)use reasonable best efforts to cause each such Registration Statement to become effective and to remain continuously effective until such time as the earlier of: (i) there are no longer Registrable Securities held by such Purchaser, or (ii) all of the Registrable Securities of such Purchaser can be sold pursuant to Rule 144 without regard to the volume-of-sale limitations imposed under Rule 144(e) (the “Effectiveness Period”) and advise such Purchaser 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 Securities Act and the Exchange Act with respect to the distribution of all of the Registrable Securities covered thereby;

(c)provide copies to such Purchaser and permit such Purchaser’s legal counsel to review each Registration Statement and all amendments and supplements at least four (4) business days in advance of their filing with the SEC; provided that the Company shall duly consider any comments received no later than two (2) business days prior to the filing of such Registration Statement, amendment or supplement, but shall not be required to accept any such comments to which it reasonably objects;

(d)furnish to such Purchaser and its legal counsel (i) immediately after the same is prepared and publicly distributed, filed with the SEC, or received by the Company (but not later than twenty-four (24) hours after the filing date, receipt date or sending date, as the case may be) one (1) 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 or it reasonably believes would constitute material and non-public information) and (ii) such number of copies of a Prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as such Purchaser may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Purchaser that are covered by the related Registration Statement;

(e)use reasonable best 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 possible moment and to notify such Purchaser of the issuance of such order and the resolution thereof;

(f)use reasonable best efforts to register or qualify (unless an exemption from the registration or qualification exists) or cooperate with such Purchaser and its counsel in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or “Blue Sky” laws of such domestic jurisdictions as are reasonably requested by such Purchaser and do any and all other reasonable acts or filings necessary or advisable to enable a 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 jurisdictions;

(g)use reasonable best 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;

(h)promptly notify such Purchaser, 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 as promptly as reasonably possible 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 reasonable best efforts to comply with all applicable rules and regulations of the SEC under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under the Securities Act, promptly inform such Purchaser 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, such Purchaser is 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;

(j)with a view to making available to such Purchaser the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit such Purchaser 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 (6) 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 Exchange Act; and (iii) furnish to such Purchaser upon request, as long as such Purchaser owns any Registrable Securities, (A) a written statement by the Company that it has complied with the reporting requirements of the Exchange 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 Purchaser of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration; and

(k)if requested by a Purchaser, cooperate with such Purchaser to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to an effective Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement and applicable law, of all restrictive legends, and to enable such certificates to be in such denominations and registered in such names as any such Purchaser may request.

(a)Such Purchaser 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 (5) business days prior to the first anticipated filing date of any Registration Statement, the Company shall notify the Purchaser of the information the Company requires from such Purchaser if the Purchaser is to have any of the Registrable Securities included in such Registration Statement. Such Purchaser shall provide such information to the Company at least two (2) business days prior to the first anticipated filing date of such Registration Statement if such Purchaser is to have any of the Registrable Securities included in such Registration Statement. If such Purchaser fails to provide to the Company the information required by this Section 4(a) by such date, the Company shall not be obligated to include such Purchaser’s Registrable Securities in such Registration Statement and shall not be obligated to pay such Purchaser liquidated damages with respect to the lack of registration of such Registrable Securities under this Agreement.

(b)Such Purchaser, 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 Purchaser has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement.

(a)Indemnification by the Company. The Company will indemnify and hold harmless each Purchaser and the officers, directors, members, employees and agents, successors and assigns of each Purchaser, and each other person, if any, who controls, or is alleged to control, any such Purchaser within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which they may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) 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 (it being understood that each Purchaser has approved Exhibit A hereto for this purpose) or (ii) any violation by the Company of any rule or regulation promulgated under the Securities Act or

Exchange Act applicable to the Company and relating to action or inaction required of the Company in connection with such registration, and the Company will reimburse each Purchaser, and each officer, director or member and each such controlling person for any legal or other 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 an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Purchaser or any such controlling person in writing specifically for use in such Registration Statement or Prospectus, and provided further that the foregoing indemnity shall not apply to amounts paid in settlement of any loss, claim, damage, liability or expense if such settlement is effected without the consent of the Company.

(b)Indemnification by the Purchasers. Each Purchaser, for any Registration Statement in which it is named as a selling stockholder, agrees 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 Securities Act) against any losses, claims, damages or liabilities resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the 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 or omission is contained in any information furnished in writing by such Purchaser to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto and has not been corrected in a subsequent writing prior to the sale of the Registrable Securities thereunder; provided, however, that the foregoing indemnity shall not apply to amounts paid in settlement of any loss, claim, damage, liability or expense if such settlement is effected without the consent of such Purchaser. In no event shall the liability of any Purchaser be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Purchaser in connection with any claim relating to this Section 5 and the amount of any damages such Purchaser has otherwise been required to pay by reason of such untrue statement or omission) received by such Purchaser upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation.

(c)Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt 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 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 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 shall not be unreasonably withheld or conditioned, 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. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or by a holder of Registrable Securities. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 5 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

(a)Amendments and Waivers. Neither this Agreement nor any provision hereof may be changed, waived, discharged, terminated, modified or amended with respect to the Company and a Purchaser only with the written consent of the Company and such Purchaser.

(b)Notices. All notices and other communications provided for or permitted hereunder shall be made as set forth in the Purchase Agreement.

(c)Assignments and Transfers by a Purchaser. The provisions of this Agreement shall be binding upon and inure to the benefit of each Purchaser and its respective successors and assigns. Each Purchaser may transfer or assign, in whole or from time to time in part, to one or more persons its rights hereunder in connection with the transfer of Registrable Securities by such Purchaser to such person, provided that such Purchaser complies with all laws applicable thereto and provides written notice of assignment to the Company promptly after such assignment is effected.

(d)Assignments and Transfers by the Company. This Agreement may not be assigned by the Company (whether by operation of law or otherwise) without the prior written consent of each Purchaser; provided, however, that 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 “Registrable Securities” shall be deemed to include the securities received by each Purchaser in connection with such transaction unless such securities are otherwise freely tradable by such Purchaser after giving effect to such transaction.

(e)Benefits of the Agreement. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

(f)Counterparts; Faxes. This Agreement may be executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other parties. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile of “.pdf” signature were the original thereof.

(g)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.

(h)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 provisions hereof prohibited or unenforceable in any respect.

(i)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.

(j)Entire Agreement. This Agreement is intended by the parties as a final expression of their agreement with respect to the registration of the Shares and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. This Agreement supersedes all prior agreements and understandings between the parties with respect to the registration of the Shares. For the avoidance of doubt, this Agreement does not supersede or replace the registration obligations of the Company to any of the Purchasers, as set forth in an investors’ rights agreement or registration rights agreement, in respect of securities of the Company (other than the Shares) held by the Purchasers.

(k)Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of California, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of Los Angeles. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of Los Angeles for the adjudication of any dispute hereunder or in connection

herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.

IN WITNESS WHEREOF, the parties have executed this Agreement or caused their duly authorized officers to execute this Agreement as of the date first above written.

The selling stockholders and any of their pledgees, donees, transferees, assignees or other successors-in-interest may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use one or more of the following methods when disposing of the shares or interests therein:

•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;

•through brokers, dealers or underwriters that may act solely as agents;

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

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

•privately negotiated transactions;

•through the writing or settlement of options or other hedging transactions entered into after the effective date of the registration statement of which this prospectus is a part, whether through an options exchange or otherwise;

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

•a combination of any such methods of disposition; and

•any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares under Rule 144 or Rule 904 under the Securities Act of 1933, as amended, or Securities Act, if available, or Section 4(a)(1) under the Securities Act, rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of 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 shares of common stock from time to time under this prospectus, or under a supplement or amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

Upon being notified in writing by a selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of common stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, we will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such selling stockholder and of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such shares of common stock were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction. In addition, upon being notified in writing by a selling stockholder that a donee or pledge intends to sell more than 500 shares of common stock, we will file a supplement to this prospectus if then required in accordance with applicable securities law.

The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of the shares of common stock or interests in shares of common stock, the selling stockholders may enter into hedging transactions after the effective date of the registration statement of which this prospectus is a part with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of common stock short after the effective date of the registration statement of which this prospectus is a part and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions after the effective date of the registration statement of which this prospectus is a part with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The maximum commission or discount to be received by any member of the Financial Industry Regulatory Authority (FINRA) or independent broker-dealer will not be greater than 8% of the initial gross proceeds from the sale of any security being sold.

We have advised the selling stockholders that they are required to comply with Regulation M promulgated under the Securities Exchange Act of 1934, as amended, during such time as they may be engaged in a distribution of the shares. The foregoing may affect the marketability of the common stock.

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

We are required to pay all fees and expenses incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act or otherwise.

We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (a) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or (b) the date on which the shares of common stock covered by this prospectus may be sold or transferred by non-affiliates without any volume limitations or pursuant to Rule 144 of the Securities Act.

“THE SHARES REPRESENTED BY THIS CERTIFICATE ARE HELD BY AN AFFILIATE OF THE ISSUER AS DEFINED IN RULE 144 PROMULGATED UNDER THE SECURITIES ACT OF 1933 AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IN COMPLIANCE WITH THE REQUIREMENTS OF RULE 144 OR PURSUANT TO A REGISTRATION STATEMENT UNDER SAID ACT OR AN EXEMPTION FROM SUCH REGISTRATION.”
