The Company is duly incorporated, validly existing and in good standing under the laws of the State of Delaware, with full corporate power and authority to conduct its business as currently conducted as disclosed in the SEC Documents. The Company is duly qualified to do business and is in good standing in every jurisdiction in which the nature of the business conducted by it or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, would not reasonably be expected to have a Material Adverse Effect.

2.2 Authorization; Enforcement. The Company has all requisite corporate power and authority to enter into and to perform its obligations under this Agreement, to consummate the transactions contemplated hereby and to issue the Securities in accordance with the terms hereof. The execution, delivery and performance of this Agreement by the Company and the consummation by it of the transactions contemplated hereby (including the issuance of the Securities and the Warrant Shares) have been duly authorized by the Company’s board of directors and no further consent or authorization of the Company, its board of directors, or its stockholders is required. This Agreement has been duly executed by the Company and constitutes a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, or moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity and except as rights to indemnity and contribution may be limited by state or federal securities laws or public policy underlying such laws.

2.3 Capitalization. The authorized capital stock of the Company consists of 125,000,000 shares of Common Stock and 100,000,000 shares of Preferred Stock. The Company’s disclosure of its issued and outstanding capital stock in its most recent SEC Document containing such disclosure was accurate in all material respects as of the date indicated in such SEC Document. Since the date indicated in such SEC Document, there has not been any change in the Company’s capital stock, other than as a result of the exercise of stock options, settlement of restricted stock units or the award of stock options or restricted stock units in the ordinary course of business pursuant to the Company’s stock-based compensation plans described in the SEC Documents. All of the issued and outstanding shares of Common Stock have been duly authorized, validly issued, fully paid, and nonassessable. The Company does not have outstanding any options to purchase, or any preemptive rights or other rights to subscribe for or to purchase, any securities

or obligations convertible into, or any contracts or commitments to issue or sell, shares of its capital stock or any such options, rights, convertible securities or obligations other than awards and purchase rights granted under the Company’s stock option plans and its employee stock purchase plan and warrants to purchase Common Stock described in the SEC Documents. The Company’s Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), as in effect on the date hereof, and the Company’s Amended and Restated Bylaws (the “Bylaws”) as in effect on the date hereof, are each filed as exhibits to the SEC Documents.

2.4 Issuance of Securities. The Shares and the Warrant Shares are duly and validly authorized and, upon issuance in accordance with the terms of this Agreement (and, in the case of the Warrant Shares, upon exercise of the Pre-Funded Warrants), will be validly issued, fully paid and nonassessable and will not be subject to preemptive rights or other similar rights of stockholders of the Company.

2.5 No Conflicts; Government Consents and Permits.

(a) The execution, delivery and performance of this Agreement by the Company and the consummation by the Company of the transactions contemplated hereby (including the issuance of the Securities and, if applicable, the Warrant Shares) will not (i) conflict with or result in a violation of any provision of the Certificate of Incorporation or Bylaws or, (ii) violate or conflict with, or result in a breach of any provision of, or constitute a default under, any agreement, indenture, or instrument to which the Company is a party, or (iii) assuming the accuracy of the representations and warranties in Article 3, result in a violation of any law, rule, regulation, order, judgment or decree (including United States federal and state securities laws and regulations and regulations of any self-regulatory organizations to which the Company or its securities are subject) applicable to the Company, except in the case of clauses (ii) and (iii) only, for such conflicts, breaches, defaults, and violations as would not reasonably be expected to have a Material Adverse Effect.

(b) The Company is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency or any regulatory or self-regulatory agency in order for it to execute, deliver or perform any of its obligations under this Agreement in accordance with the terms hereof, or to issue and sell the Securities in accordance with the terms hereof other than such as have been made or obtained, and except for (i) the registration of the Shares and the Warrant Shares under the Securities Act pursuant to Article 6 hereof, (ii) any filings required to be made under federal or state securities laws after the date hereof, (iii) any required filings or notifications regarding the issuance or listing of additional shares with Nasdaq, and (iv) the filing of a Notice of Sale of Securities on Form D with the SEC under Regulation D of the Securities Act.

(c) The Company has all permits, licenses, and any similar authority necessary for the conduct of its business as now being conducted by it and as currently proposed to be conducted as disclosed in the SEC Documents, except for such permit, license or similar authority, the lack of which would not reasonably be expected to have a Material Adverse Effect. The Company has not received any actual notice of any proceeding relating to revocation or modification of any such permit, license, or similar authority except where such revocation or modification would not reasonably be expected to have a Material Adverse Effect.

2.6 SEC Documents, Financial Statements. The Company has timely filed all reports, schedules, forms, statements and other documents required to be filed by it with the SEC since January 1, 2023, pursuant to the reporting requirements of the Exchange Act (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial statements and schedules thereto and documents (other than exhibits) incorporated by reference therein, being hereinafter referred to herein as the “SEC Documents”). As of the date hereof, the Company is eligible to register its Common Stock for resale using

Form S-3 promulgated under the Securities Act. The Company has delivered to each Purchaser, or each Purchaser has had access to, true and complete copies of the SEC Documents. The Company is not, and never has been, a “shell company” (as defined in Rule 12b-2 under the Exchange Act). As of their respective dates, the SEC Documents complied in all material respects with the requirements of the Exchange Act or the Securities Act, as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. As of their respective dates, the Financial Statements and the related notes complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. The Financial Statements and the related notes have been prepared in accordance with accounting principles generally accepted in the United States, consistently applied, during the periods involved (except (a) as may be otherwise indicated in the Financial Statements or the notes thereto, or (b) in the case of unaudited interim statements, to the extent they may not include footnotes, may be condensed or summary statements or may conform to the SEC’s rules and instructions for Quarterly Reports on Form 10-Q) and fairly present in all material respects the consolidated financial position of the Company as of the dates thereof and the consolidated results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal and recurring year-end audit adjustments). All material agreements that were required to be filed as exhibits to the Company’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K under Item 601(b)(10) of Regulation S-K (collectively, the “Material Agreements”) to which the Company or any Subsidiary of the Company is a party, or the property or assets of the Company or any Subsidiary of the Company are subject, have been filed as exhibits to the SEC Documents. All Material Agreements are valid and enforceable against the Company in accordance with their respective terms, except (i) as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, or moratorium or similar laws affecting creditors’ and contracting parties’ rights generally, and (ii) as enforceability may be subject to general principles of equity and except as rights to indemnity and contribution may be limited by state or federal securities laws or public policy underlying such laws. The Company is not in breach of or default under any of the Material Agreements, and to the Company’s knowledge, no other party to a Material Agreement is in breach of or default under such Material Agreement, except in each case, for such breaches or defaults as would not reasonably be expected to have a Material Adverse Effect. The Company has not received a notice of termination nor is the Company otherwise aware of any threats to terminate any of the Material Agreements.

2.7 Disclosure Controls and Procedures. The Company has established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and the Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the most recently filed quarterly or annual periodic report under the Exchange Act (such date, the “Evaluation Date”). Since the Evaluation Date, there have been no significant changes in the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal control over financial reporting.

2.8 Accounting Controls. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurances that (a) transactions are executed in accordance with management’s general or specific authorization, (b) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles as applied in the United States and to maintain accountability for assets, (c) access to assets is permitted only in accordance with management’s general or specific authorization, and (d) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

2.9 Absence of Litigation. As of the date hereof, there is no action, suit, proceeding or investigation before or by any court, public board, government agency, self-regulatory organization or body pending or, to the Company’s knowledge, threatened against the Company that if determined adversely to the Company would reasonably be expected to have a Material Adverse Effect or would reasonably be expected to impair the ability of the Company to perform its obligations under this Agreement. To the knowledge of the Company, there is not pending or contemplated any investigation by the SEC of the Company or any director or executive officer of the Company. The Company has not received any stop order or other order suspending the effectiveness of any registration statement filed by the Company under the Exchange Act or the Securities Act and, to the Company’s knowledge, the SEC has not issued any such order.

2.10 Intellectual Property Rights. The Company owns or possesses, or has a reasonable basis on which it believes it can obtain on reasonable terms, licenses or sufficient rights to use all patents, patent applications, patent rights, inventions, know-how, trade secrets, trademarks, trademark applications, service marks, service names, trade names and copyrights necessary to enable it to conduct its business as conducted as of the date hereof and, to its knowledge, as proposed to be conducted as described in the SEC Documents. As used in this Agreement, the “Intellectual Property” means all patents, patent applications, patent rights, inventions, know-how, trade secrets, trademarks, trademark applications, service marks, service names, trade names and copyrights necessary to enable the Company to conduct its business as conducted as of the date hereof and, to its knowledge, as proposed to be conducted as described in the SEC Documents. The Company has not infringed the intellectual property rights of third parties and no third party, to the Company’s knowledge, is infringing the Intellectual Property, in each case, which could reasonably be expected to result in a Material Adverse Effect. There are no material options, licenses or agreements relating to the Intellectual Property that are not described in the SEC Documents, nor is the Company bound by or a party to any material options, licenses or agreements relating to the patents, patent applications, patent rights, inventions, know-how, trade secrets, trademarks, trademark applications, service marks, service names, trade names or copyrights of any other Person that are not described in the SEC Documents. There is no material claim or action or proceeding pending or, to the Company’s knowledge, threatened that challenges any of the rights of the Company in or to, or otherwise with respect to, any Intellectual Property.

2.11 Investment Company. The Company is not and, after giving effect to the offering and sale of the Securities and the assumed exercise in full of the Pre-Funded Warrants, will not be, an “investment company” as such term is defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company has no commitments or plans with respect to operating its business that would cause it to become subject to the Investment Company Act.

2.12 No Material Adverse Change. Since March 31, 2023, except as described or referred to in the SEC Documents and except for cash expenditures in the ordinary course of business, there has not been any change in the assets, business, properties, financial condition or results of operations of the Company that could reasonably be expected to have a Material Adverse Effect. Since March 31, 2023, (a) there has not been any dividend or distribution of any kind declared, set aside for payment, paid or made by the Company on any class of capital stock, (b) the Company has not sustained any material loss or interference with the Company’s business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor disturbance or dispute or any action, order or decree of any court or arbitrator or governmental or regulatory authority, and (c) the Company has not incurred any material liabilities except in the ordinary course of business.

2.13 The Nasdaq Capital Market. The Common Stock is listed on The Nasdaq Capital Market, and, to the Company’s knowledge, there are no proceedings to revoke or suspend such listing. As of the date hereof, the Company is in material compliance with the requirements of Nasdaq for continued listing of the Common Stock thereon and any other Nasdaq listing and maintenance requirements.

2.14 Accountants. Deloitte & Touche LLP, which has expressed its opinion with respect to the audited financial statements included as a part of the SEC Documents, are independent accountants as required by the Securities Act.

2.15 Insurance. The Company is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as the Company believes are prudent and customary for a company (a) in the businesses and location in which the Company is engaged, (b) with the resources of the Company, and (c) at a similar stage of development as the Company. The Company has not received any written notice that the Company will not be able to renew its existing insurance coverage as and when such coverage expires. The Company believes it will be able to obtain similar coverage at reasonable cost from similar insurers as may be necessary to continue its business.

2.16 Foreign Corrupt Practices. Since January 1, 2021, neither the Company, any director, officer, or employee of the Company, nor to the Company’s knowledge, any agent or other Person acting on behalf of the Company has, in the course of its actions for, or on behalf of, the Company (a) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity, (b) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds, (c) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or (d) made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee.

Neither the Company, nor any Person acting on its behalf, has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under any circumstances that would require registration of the Securities under the Securities Act. Assuming the accuracy of the representations and warranties of the Purchasers contained in Article 3 hereof and the accuracy of the information disclosed in the Accredited Investor Questionnaires provided by the Purchasers, the issuance of the Securities and the Warrant Shares are exempt from registration under the Securities Act.

2.18 No Registration Rights. No Person has the right to (a) prohibit the Company from filing a Registration Statement or (b) require the Company to register any securities for sale under the Securities Act by reason of the filing of a Registration Statement. The granting and performance of the registration rights under this Agreement will not violate or conflict with, or result in a breach of any provision of, or constitute a default under, any agreement, indenture, or instrument to which the Company is a party.

2.19 Taxes. The Company has filed all tax returns required to be filed by it and has paid all taxes that are material in amount and shown as due on such tax returns, except where the failure to so file or the failure to so pay would not reasonably be expected to have a Material Adverse Effect.

2.20 Real and Personal Property. The Company has good and marketable title to, or has valid rights to lease or otherwise use, all items of real and personal property that are material to the business of the Company as currently conducted and as described in the SEC Documents free and clear of all liens, encumbrances, claims and defects and imperfections of title except those that (a) do not materially interfere with the use of such property by the Company or (b) would not reasonably be expected to have a Material Adverse Effect.

ARTICLE 3

PURCHASER’S REPRESENTATIONS AND WARRANTIES

Each Purchaser represents and warrants to the Company, severally and not jointly, with respect to itself and its purchase hereunder, that:

3.1 Organization; Authority. Such Purchaser is an entity validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate or partnership power and authority to enter into and to consummate the transactions contemplated by this Agreement. The execution and delivery of this Agreement by such Purchaser and performance by such Purchaser of the transactions contemplated hereby have been duly authorized by all necessary corporate or, if such Purchaser is not a corporation, such partnership, limited liability company or other applicable like action, on the part of such Purchaser. This Agreement has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity and except as rights to indemnity and contribution may be limited by state or federal securities laws or public policy underlying such laws.

3.2 No Conflict. The execution, delivery and performance of the Agreement by such Purchaser and the consummation by such Purchaser of the transactions contemplated hereby do not and will not (i) violate any provision of such Purchaser’s charter or organizational documents, (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, mortgage, deed of trust, indenture, note, bond, license, lease agreement, instrument or obligation to which such Purchaser is a party or by which such Purchaser’s properties or assets are bound, or (iii) result in a violation of any federal, state, local or foreign statute, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to such Purchaser or by which any property or asset of such Purchaser are bound or affected, except, in the case of clauses (ii) and (iii) for such conflicts, defaults or violations that would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Purchaser to perform its obligations under this Agreement, including the purchase of the Securities.

3.3 Investment Purpose. The Purchaser is purchasing the Securities for its own account and not with a present view toward the public sale or distribution thereof in violation of the Securities Act and has no intention of selling or distributing any of such Securities or any arrangement or understanding with any other Persons regarding the sale or distribution of such Securities except in accordance with the provisions of Article 6 and except as would not result in a violation of the Securities Act. The Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Securities except in accordance with the provisions of Article 6 or pursuant to and in accordance with the Securities Act. The Securities are being purchased by such Purchaser in the ordinary course of its business. By making the representations herein, such Purchaser does not agree to hold any of the Securities for any minimum or other specific term and reserves the right to assign, transfer or otherwise dispose of any of the Securities at any time in accordance with or pursuant to a registration statement or a valid exemption under the Securities Act.

3.4 Information. The Purchaser has been given access to all relevant materials relating to the business, finances and operations of the Company necessary to make an investment decision, and materials relating to the offer and sale of the Securities, that have been requested by the Purchaser, including, without limitation, the SEC Documents, and the Purchaser has had the opportunity to review the SEC Documents. The Purchaser has been afforded the opportunity to ask questions of the Company. Neither the Purchaser’s review or inquiries, nor any other due diligence investigations conducted by the Purchaser or its advisors, if any, or its representatives shall modify, amend or affect the Purchaser’s right to rely on the Company’s representations and warranties contained herein or in the Pre-Funded Warrants.

3.5 Acknowledgement of Risk.

(a) The Purchaser acknowledges and understands that its investment in the Securities involves a significant degree of risk, including, without limitation, (i) the Company remains a clinical stage business and requires substantial funds in addition to the proceeds from the sale of the Securities, (ii) an investment in the Company is speculative, and only Purchasers who can afford the loss of their entire investment should consider investing in the Company and the Securities, (iii) the Purchaser may not be able to liquidate its investment, (iv) transferability of the Securities is extremely limited, (v) in the event of a disposition of the Securities, the Purchaser could sustain the loss of its entire investment, and (vi) the Company has not paid any dividends on its Common Stock since inception and does not anticipate the payment of dividends in the foreseeable future. Such risks are more fully set forth in the SEC Documents;

(b) The Purchaser is able to bear the economic risk of holding the Securities for an indefinite period, and has knowledge and experience in financial and business matters such that it is capable of evaluating the risks of the investment in the Securities; and

(c) The Purchaser has, in connection with the Purchaser’s decision to purchase Securities, not relied upon any representations or other information (whether oral or written) other than as set forth in the representations and warranties of the Company contained herein and the information disclosed in the SEC Documents, and the Purchaser has, with respect to all matters relating to this Agreement and the offer and sale of the Securities, relied solely upon the advice of such Purchaser’s own counsel and has not relied upon or consulted any counsel to the Company.

3.6 Governmental Review. The Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or endorsement of the Securities or an investment therein.

3.7 Transfer or Resale. The Purchaser understands that:

(a) the Securities and the 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 Securities Act only in certain limited circumstances;

(b) neither the Securities nor the Warrant Shares have been, and neither are being, registered under the Securities Act (other than as contemplated in Article 6) or any applicable state securities laws and, consequently, the Purchaser may have to bear the risk of owning the Securities and the Warrant Shares, if applicable, for an indefinite period of time because the Securities and the Warrant Shares, if applicable, may not be transferred unless (i) the resale of the Securities and the Warrant Shares, if applicable, is registered pursuant to an effective registration statement under the Securities Act, as contemplated in Article 6, (ii) the Purchaser has delivered to the Company an opinion of counsel (in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the Shares and the Warrant Shares, if applicable, to be sold or transferred may be sold or transferred pursuant to an exemption from such registration, or (iii) the Securities and the Warrant Shares, if applicable, are sold or transferred pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of a seller representation letter) that the securities may be sold pursuant to such rule);

(c) any sale of the Securities or the Warrant Shares, as applicable, made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and, if Rule 144 is not applicable, any resale of the Securities or the Warrant Shares, as applicable, under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder; and

(d) except as set forth in Article 6, neither the Company nor any other Person is under any obligation to register the resale of the Securities or the Warrant Shares, as applicable, under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder in connection with the resale of the Securities or the Warrant Shares, as applicable.

3.8 Legends.

(a) Without limiting the Company’s registration obligations in Section 6.1, the Purchaser understands that any certificates representing the Securities will bear a restrictive legend in substantially the following form, in addition to any other legend required by applicable state securities laws or as may be appropriate to legend any restrictions on transfer set forth in this Agreement (and a stop-transfer order may be placed against transfer of the certificates for such Securities):

NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS, OR UNLESS OFFERED, SOLD, PLEDGED, HYPOTHECATED OR TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS. THE COMPANY SHALL BE ENTITLED TO REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED TO THE EXTENT THAT SUCH OPINION IS REQUIRED PURSUANT TO THAT CERTAIN SECURITIES PURCHASE AGREEMENT UNDER WHICH THE SECURITIES WERE ISSUED.

(b) To the extent the resale of the Shares or Warrant Shares is registered under the Securities Act pursuant to an effective Registration Statement, the Company agrees to promptly (i) authorize the removal of the legend set forth in Section 3.8(a) and any other legend not required by applicable law from such Shares or Warrant Shares and (ii) cause its transfer agent to issue such Shares or Warrant Shares without such legends to the holders thereof by electronic delivery at the applicable balance accounts of the holders or their designees at the Depository Trust Company (“DTC”) within two Business Days after surrender of any stock certificates evidencing such Shares or Warrant Shares or after exercise of the Pre-Funded Warrants, as applicable. With respect to any Shares or Warrant Shares for which restrictive legends are removed pursuant to this Section 3.8(b), the holder thereof agrees to only sell such Shares or Warrant Shares when and as permitted by the effective Registration Statement covering such resale or pursuant to Rule 144 and in accordance with applicable securities laws and regulations.

(c) The Purchaser may request that the Company remove, and the Company agrees to authorize the removal of, any legend from the Shares or Warrant Shares (if outstanding), and shall cause its transfer agent to issue book entry statements without such legend or any other legend to the holder of the applicable Shares or Warrant Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at DTC, if (i) sold or transferred pursuant to the effective registration statement registering such securities for resale (during such time that such registration statement is effective and not withdrawn or suspended, and only as permitted by such registration statement) or following any sale of such Shares or Warrant Shares pursuant to Rule 144, or (ii) if such Shares or Warrant Shares are eligible for sale under Rule 144 following the expiration of the one-year holding requirement under subparagraphs (b)(1)(i) and (d) thereof (giving effect to any tacking in the case of a proper cashless exercise of the Pre-Funded Warrants) and the Purchaser is not an Affiliate of the Company, in each case following receipt from the Purchaser of an appropriate certification to such effect. Following the time a legend is no longer required for the Shares or Warrant Shares under this Section 3.8(c), the Company will, no later than two (2) Business Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such securities, if applicable, and appropriate certifications that the applicable requirements have been satisfied, deliver or cause to be delivered to such Purchaser such securities that are free from all restrictive and other legends by electronic delivery to such Purchaser’s or its designee’s balance account at DTC.

The Purchaser has taken all necessary action to authorize the execution, delivery and performance of this Agreement. Upon the execution and delivery of this Agreement, this Agreement shall constitute a valid and binding obligation of the Purchaser enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity and except as rights to indemnity and contribution may be limited by state or federal securities laws or public policy underlying such laws.

Such Purchaser has executed and delivered to the Company an Accredited Investor Questionnaire in substantially the form attached hereto as Exhibit C, which such Purchaser represents and warrants is true, correct and complete. Neither the Purchaser nor any of its Rule 506(d) Related Parties is a “bad actor” within the meaning of Rule 506(d) of the Securities Act. For purposes of this Agreement, a “Rule 506(d) Related Party” shall mean a person or entity covered by the “Bad Actor disqualification” provision of Rule 506(d) of the Securities Act.

3.12 Foreign Purchasers. If any Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended) or is a U.S. subsidiary or affiliate of a foreign parent company (a “Foreign Purchaser”), each such Foreign Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or the Warrant Shares or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Securities or the Warrant Shares, (b) any foreign exchange restrictions applicable to such purchase, (c) any government or other consents that may need to be obtained, and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Securities or the Warrant Shares. Each Foreign Purchaser further represents that either (i) it does not now, nor will it after the Closing, hold 10% or greater, directly or indirectly, of the voting interest in the Company or (ii) if it does or will, such Foreign Purchaser shall notify the Company and shall provide such information as the Company may reasonably request to comply with state, federal, or local regulations. The Company’s offer and sale and the Foreign Purchaser’s subscription and payment for and continued beneficial ownership of the Securities or the Warrant Shares will not violate any applicable securities or other laws of the Foreign Purchaser’s jurisdiction.

Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or, to the knowledge of such Purchaser, any other general solicitation or general advertisement.

3.14 Brokers and Finders. No Person will have, as a result of the sales of the Securities, including the exercise of the Pre-Funded Warrants, if any, any valid right, interest or claim against or upon the Company or any Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of such Purchaser.

3.15 No Intent to Effect a Change of Control. Such Purchaser has no present intent to effect a “change of control” of the Company as such term is understood under the rules promulgated pursuant to Section 13(d) of the Exchange Act.

4.6 Board Observer. During the period commencing on the Closing and ending on the earlier of (i) the occurrence of a Change of Control (as defined below) and (ii) the date that Boehringer Ingelheim International GmbH (together with its Affiliates, “BI”) holds less than 10% of the Company’s Common Stock (which shall be calculated by including in the amount of Common Stock held by BI any Warrant Shares issuable upon exercise of any portion of the Pre-Funded Warrant issued to BI and not yet exercised by BI), then BI shall have the right to designate one (1) natural person, reasonably acceptable to the Company, to be present and participate in a non-voting, observer capacity at all meetings of the board of directors of the Company or any committee thereof, including any telephonic or electronic meetings (such individual, the “Board Observer”); provided, for the avoidance of doubt, that in no event shall the Board Observer: (i) be deemed to be a member of the board of directors or any committee thereof or (ii) have the right to vote on, consent to or veto any matter, motion or resolution presented to the board of directors or any committee thereof or propose or offer any motions or resolutions to the board of directors or any committee thereof. Any materials that are sent by the Company to the members of the board of directors in their capacity as such shall be sent to the Board Observer substantially simultaneously by means reasonably designed to ensure timely receipt by the Board Observer, and the Company will give the Board Observer

notice of such meetings, by the same means as such notices are delivered to the members of the board of directors and at the same time as notice is provided or delivered to the board of directors; provided, that the Board Observer agrees to be subject to the Company’s Code of Ethics and Business Conduct and other policies and procedures to the same extent as a member of the board of directors, to hold in confidence and trust, to act in a fiduciary manner with respect to and not to disclose any information provided to or learned by them acting in such capacity, whether in connection with the Board Observer’s attendance at meetings of the board of directors or any committee thereof, in connection with the receipt of materials delivered to the board of directors or any committee thereof or otherwise. Notwithstanding the provisions of this Section 4.6, the Company reserves the right to exclude the Board Observer from any meeting of the board of directors, or a portion thereof, and to redact portions of any materials delivered to the Board Observer, where and to the extent that the Company reasonably believes that (i) withholding such information or excluding the Board Observer from attending such meeting of the board of directors, or a portion thereof, is reasonably necessary to preserve attorney-client, work product or similar privilege between the Company, its board of directors or any committee thereof, on the one hand, and its counsel, on the other, with respect to any matter; (ii) withholding such information or excluding the Board Observer from attending such meeting of the board of directors, or a portion thereof, is reasonably necessary to protect trade secrets or to comply with the terms and conditions of confidentiality agreements between the Company and any third parties; (iii) such board materials or any meeting of the board of directors or committee thereof relates directly to the Company’s relationship, contractual or otherwise, with BI, or (iv) because the board of directors of the Company has determined in good faith that there exists, with respect to the subject of such deliberation or such information, an actual or potential conflict of interest between BI and the Company. The Board Observer shall use the same degree of care to protect the Company’s confidential and proprietary information as BI uses to protect confidential and proprietary information of like nature, but in no circumstances with less than reasonable care. Notwithstanding the foregoing, BI’s right to designate the Board Observer shall be suspended for so as long as the Board Observer serves as a director on the board of directors of the Company. For the avoidance of doubt, the Board Observer shall not be compensated by the Company in such capacity but may be eligible for reimbursement for reasonable and documented out-of-pocket expenses in accordance with any applicable policy of the Company then in effect, provided, however, that the Board Observer has not been otherwise reimbursed by BI for any such expenses.

4.7 Short Sales and Confidentiality After The Date Hereof. Each Purchaser shall not, and shall cause its Affiliates not to, engage, directly or indirectly, in any transactions in the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) during the period from the date hereof until such time as the transactions contemplated by this Agreement are first publicly disclosed as required by and described in Section 4.4 of this Agreement. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company as described in Section 4.4 of this Agreement, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in this Agreement. Notwithstanding the foregoing, in the event that a Purchaser 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 apply only with respect to the portion of assets managed by the portfolio manager that have knowledge about the financing transaction contemplated by this Agreement.

4.8 Reservation of Common Stock. The Company shall reserve and keep available at all times during which any Pre-Funded Warrant remains exercisable, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Warrant Shares upon exercise of the Pre-Funded Warrants in accordance with the terms thereof.

REGISTRATION RIGHTS

6.1 On or before the date that is 45 days after the Closing Date (the “Filing Date”), the Company shall file a registration statement covering the resale of the Registrable Securities with the SEC for an offering to be made on a continuous basis pursuant to Rule 415, or if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as the Holders of a majority of the Registrable Securities may reasonably specify (the “Initial Registration Statement”). The Initial Registration Statement shall be on Form S-3 (except if the Company is ineligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form), and the Company shall effect the registration, qualifications or compliances (including, without limitation, the execution of any required undertaking to file post-effective amendments, appropriate qualifications or exemptions under applicable blue sky or other state securities laws and appropriate compliance with applicable securities laws, requirements or regulations) as promptly as possible after the filing thereof, but in any event prior to the date which is 75 days in the event of no review by the SEC, or 95 days in the event of a review by the SEC, after the Closing Date. Notwithstanding anything else herein to the contrary, the Company’s obligation to register the Shares and the Warrant Shares shall continue at least until a Registration Statement or Registration Statements covering the resale of all Shares and the Warrant Shares held by Holders are or have become effective and shall not be canceled prior to that time by the fact that any Shares or Warrant Shares become eligible for sale under Rule 144. In the event the SEC informs the Company that all of the Registrable Securities cannot, as a result of the

application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (a) inform each of the Holders thereof, (b) use its reasonable best efforts to file amendments to the Initial Registration Statement as required by the SEC and/or (c) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the SEC, on Form S-3 or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its reasonable best efforts to advocate with the SEC for the registration of all of the Registrable Securities. In the event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (b) or (c) above, the Company will use its best efforts to file with the SEC, as promptly as allowed by the SEC, one or more registration statements on Form S-3 or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”). Notwithstanding any other provision of this Agreement, if the SEC limits the number of Registrable Securities permitted to be registered on a particular Registration Statement (and notwithstanding that the Company used diligent efforts to advocate with the SEC for the registration of all or a greater number of Registrable Securities), any required cutback of Registrable Securities shall be applied to the Purchasers pro rata in accordance with the number of such Registrable Securities sought to be included in such Registration Statement by reference to the amount of Registrable Securities set forth opposite such Purchaser’s name on Exhibit A (and in the case of a subsequent transfer, the initial Purchaser’s transferee) relative to the aggregate amount of all Registrable Securities.

6.2 All Registration Expenses incurred in connection with any registration, qualification, exemption or compliance pursuant to Section 6.1 shall be borne by the Company. All Selling Expenses relating to the sale of securities registered by or on behalf of any Holder shall be borne by such Holder.

6.3 In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform each Holder as to the status of such registration, qualification, exemption and compliance. At its expense the Company shall:

(a) except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Company determines to obtain, continuously effective with respect to a Holder, and to keep the applicable Registration Statement free of any material misstatements or omissions, until the earlier of the following: (i) the third anniversary of the effective date of the Initial Registration Statement, (ii) the date all Shares and, if applicable, Warrant Shares held by such Holder may be sold under Rule 144 without being subject to any volume, manner of sale or publicly available information requirements or (iii) immediately prior to the closing of a Change of Control. The period of time during which the Company is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period.”

(b) advise the Holders within five (5) Business Days:

(i) when a Registration Statement or any amendment thereto (other than an amendment pursuant to a periodic or current report) has been filed with the SEC and when such Registration Statement or any post-effective amendment thereto has become effective;

(ii) of any request by the SEC for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; and

(iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(c) use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(d) if a Holder so requests in writing, promptly furnish to each such Holder, without charge, at least one copy of each Registration Statement and each post-effective amendment thereto, including financial statements and schedules, and, if explicitly requested, all exhibits in the form filed with the SEC;

(e) during the Registration Period, if a Holder so requests in writing, deliver to each Holder, without charge, (i) one copy of the following documents, other than those documents available via XXXXX: (A) its annual report to its stockholders, if any (which annual report shall contain financial statements audited in accordance with generally accepted accounting principles in the United States of America by a firm of certified public accountants of recognized standing), (B) if not included in substance in its annual report to stockholders, its annual report on Form 10-K (or similar form), (C) its definitive proxy statement with respect to its annual meeting of stockholders, (D) each of its quarterly reports to its stockholders, and, if not included in substance in its quarterly reports to stockholders, its quarterly report on Form 10-Q (or similar form), and (E) a copy of each full Registration Statement (the foregoing, in each case, excluding exhibits); and (ii) if explicitly requested, all exhibits excluded by the parenthetical to the immediately preceding clause (E);

(f) prior to any public offering of Registrable Securities pursuant to any Registration Statement, promptly take such actions as may be necessary to register or qualify or obtain an exemption for offer and sale under the securities or blue sky laws of such United States jurisdictions as any such Holders reasonably request in writing, provided that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Securities covered by any such Registration Statement;

(g) upon the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, except for such times as the Company is permitted hereunder to suspend the use of a prospectus forming part of a Registration Statement, the Company shall use its best efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(h) use its commercially reasonable efforts to cause all Registrable Securities to be listed on each securities exchange or market, if any, on which the Common Stock is then listed;

(i) use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated hereby and to enable the Holders to sell Registrable Securities under Rule 144;

(j) provide to each Purchaser and its representatives, if requested, the opportunity to conduct a reasonable inquiry of the Company’s financial and other records during normal business hours and make available its officers, directors and employees for questions regarding information which such Purchaser may reasonably request in order to fulfill any due diligence obligation on its part; and

(k) permit counsel for each Purchaser to review any Registration Statement and all amendments and supplements thereto (other than supplements to a Registration Statement on Form S-1 solely for the purpose of incorporating other filings with the SEC into such Registration Statement and other than an amendment to a Registration Statement on Form S-1 or Form S-3 for the purpose of converting such Registration Statement into a Registration Statement on Form S-3), within three (3) Business Days prior to the filing thereof with the SEC;

provided that, in the case of clauses (j) and (k) above, the Company shall not be required (A) to delay the filing of any Registration Statement or any amendment or supplement thereto as a result of any ongoing diligence inquiry by or on behalf of a Holder or to incorporate any comments to any Registration Statement or any amendment or supplement thereto by or on behalf of a Holder if such inquiry or comments would require a delay in the filing of such Registration Statement, amendment or supplement, as the case may be, or (B) to provide, and shall not provide, any Purchaser or its representatives with material, non-public information unless such Purchaser agrees to receive such information and enters into a written confidentiality agreement with the Company in a form reasonably acceptable to the Company.

6.4 The Holders shall have no right to take any action to restrain, enjoin or otherwise delay any registration pursuant to Section 6.1 hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement.

6.5 (a) To the extent permitted by law, the Company shall indemnify each Holder and each Person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.5(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse each Holder and each Person controlling such Holder, for reasonable and documented out-of-pocket expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Holder for use in preparation of any Registration Statement, prospectus, amendment or supplement; provided further, that the Company will not be liable in any such case where the claim, loss, damage or liability arises out of or is related to the failure of any Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus but eliminated or remedied

in the amended prospectus on file with the SEC at the time any Registration Statement becomes effective or in an amended prospectus filed with the SEC pursuant to Rule 424(b) which meets the requirements of Section 10(a) of the Securities Act (each, a “Final Prospectus”), such indemnity shall not inure to the benefit of any such Holder or any such controlling Person, if a copy of a Final Prospectus furnished by the Company to the Holder for delivery was not furnished or deemed delivered to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, liability, claim or damage.

(b) Each Holder will severally, and not jointly, indemnify the Company, each of its directors and officers, and each Person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.5(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, or any amendment or supplement thereof, to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers, and each Person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder for use in preparation of any Registration Statement, prospectus, amendment or supplement; provided that the indemnity shall not apply to the extent that such claim, loss, damage or liability results from the fact that a current copy of a prospectus was not made available to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, claim, damage or liability. Notwithstanding the foregoing, a Holder’s aggregate liability pursuant to this subsection (b) and subsection (d) shall be limited to the net amount received by the Holder from the sale of the Registrable Securities.

(c) Each party entitled to indemnification under this Section 6.5 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense, 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 under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent will not be unreasonably withheld). No Indemnifying Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which 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 to such claim or litigation.

(d) If the indemnification provided for in this Section 6.5 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in

connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

6.6 (a) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Securities so that, as thereafter delivered to the Holders, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement and prospectus contemplated by Section 6.1 until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

(b) Each Holder shall suspend, upon request of the Company, any disposition of Registrable Securities pursuant to any Registration Statement and prospectus contemplated by Section 6.1 during no more than two periods of no more than 30 calendar days each during any 12-month period if and only if the board of directors of the Company determines in good faith that the sale of such Holder’s Registrable Securities under any such Registration Statement would be reasonably likely to cause a violation of the Securities Act or Exchange Act.

(c) As a condition to the inclusion of its Registrable Securities, each Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing, including completing a Registration Statement Questionnaire in the form provided by the Company, or as shall be required in connection with any registration referred to in this Article 6.

(d) Each Holder hereby covenants with the Company not to make any sale of the Registrable Securities pursuant to a Registration Statement without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied.

(e) At the end of the Registration Period the Holders shall discontinue sales of shares pursuant to any Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by any such Registration Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold promptly upon receipt of such notice from the Company.

6.7 With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which at any time permit the sale of the Registrable Securities to the public without registration, so long as the Holders still own Registrable Securities (including Warrant Shares issuable upon exercise of any unexercised portion of a Pre-Funded Warrant), the Company shall use best efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times;

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Exchange Act; and

(c) so long as a Holder owns any Registrable Securities, furnish to such Holder, upon any reasonable request, a written statement by the Company as to its compliance with Rule 144 under the Securities Act, and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing a Holder to sell any such securities without registration.

6.8 The rights to cause the Company to register Registrable Securities granted to the Holders by the Company under Section 6.1 may be assigned by a Holder in connection with a transfer by such Holder of all or a portion of its Registrable Securities, provided, however, that such transfer must be made at least ten (10) days prior to the Filing Date and that (i) such transfer may otherwise be effected in accordance with applicable securities laws; (ii) such Holder gives prior written notice to the Company at least ten days prior to the Filing Date; and (iii) such transferee agrees to comply with the terms and provisions of this Agreement, and such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 6.8, the rights of a Holder with respect to Registrable Securities as set out herein shall not be transferable to any other Person, and any attempted transfer shall cause all rights of such Holder therein to be forfeited.

6.9 The rights of any Holder under any provision of this Article 6 may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended by an instrument in writing signed by such Xxxxxx.

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 suits, action, proceeding or judgement 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 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 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. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any suit, action or proceeding. TO THE EXTENT ALLOWABLE UNDER APPLICABLE LAW, EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS

AGREEMENT OR THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF.

Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signatures complying with the U.S. federal ESIGN Act of 2000, e.g., xxx.xxxxxxxx.xxx) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

8.3 Headings. The headings of this Agreement are for convenience of reference only, are not part of this Agreement and do not affect its interpretation.

8.4 Severability. If any provision of this Agreement is invalid or unenforceable under any applicable statute or rule of law, then such provision will be deemed modified in order to conform with such statute or rule of law. Any provision hereof that may prove invalid or unenforceable under any law will not affect the validity or enforceability of any other provision hereof.

8.5 Entire Agreement; Amendments. This Agreement (including all schedules and exhibits hereto) constitutes the entire agreement among the parties hereto with respect to the subject matter hereof and thereof. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or therein.

This Agreement and any provision hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the Company and the Purchaser to be charged with enforcement of such modification, amendment or waiver. Any amendment or waiver by a party effected in accordance with this Section 8.5 shall be binding upon the applicable Purchaser, including with respect to any Securities purchased under this Agreement or Warrant Shares at the time outstanding and held by such party (including securities into which such Securities are convertible and for which such Securities are exercisable) and each future holder of all such Securities.
