Investors so agree. At the Initial Closing, each Investor shall pay to an account designated by the Company, by wire transfer of immediately available funds, the dollar amount set forth opposite its name on Exhibit A hereto under the heading “Initial Closing Aggregate Purchase Price”. Subject to receipt of the foregoing payment, the Company will (i) instruct the Transfer Agent to credit each Investor the number of Closing Shares set forth opposite its name on Exhibit A hereto under the heading “Initial Closing Shares”, (ii) if applicable, deliver to such Investor the Pre-Funded Warrants set forth opposite its name on Exhibit A hereto under the heading “Pre-Funded Warrants”, and (iii) as promptly as practical, deliver, or cause the Transfer Agent to deliver, written evidence of the issuance to the Investor of such Closing Shares on and as of the Initial Closing Date. In the event that the Initial Closing has not occurred within five Business Days after date hereof, unless otherwise agreed by the Company and such Investor, the Company shall promptly (but no later than one Business Day thereafter) return the previously wired amounts to each respective Investor by wire transfer of United States dollars in immediately available funds to the account specified by each Investor, and any book entries for the Securities shall be deemed cancelled; provided that, unless this Agreement has been terminated pursuant to Section 7, such return of funds shall not terminate this Agreement or relieve such Investor of its obligation to purchase, or the Company of its obligation to issue and sell, the Securities at the Initial Closing.

2.2 Milestone Closing.

(a) Subject to the achievement of the Milestone Event and either (i) the achievement of the Price Threshold or (ii) the Company’s receipt of a Price Threshold Waiver (the “Milestone Closing Trigger”), the Company shall, within two Business Days thereafter, provide written notice to the Investors of such Milestone Closing Trigger (the “Milestone Event Notice” and the date the Milestone Closing Notice is delivered, the “Milestone Event Notice Date”), and as a result, a milestone closing under this Agreement (the “Milestone Closing”) shall be held.

At the Milestone Closing, the Company agrees to sell, and each Investor, severally and not jointly, agrees to purchase, the number of Closing Shares equal to (x) the dollar amount set forth opposite such Investor’s name on Exhibit A hereto under the heading “Milestone Closing Subscription Amount” divided by (y) the Share Price, rounded down to the nearest whole Closing Share; provided, however, in the event the number of Closing Shares to be purchased by an Investor at the Milestone Closing would otherwise result in such Investor, together with its Attribution Parties, beneficially owning in excess of 19.99% (or at the Investor’s election, 9.99%) of the outstanding Common Stock immediately after the Milestone Closing (the “Beneficial Ownership Limitation”), then (i) the number of Closing Shares otherwise issuable to such Investor at the Milestone Closing will be reduced by the minimum number of Closing Shares (such number, the “Milestone Overage Number”) that would result in such Investor beneficially owning, together with its Attribution Parties, no more than the Beneficial Ownership Limitation of the outstanding Common Stock immediately after the Milestone Closing, and (ii) in lieu of purchasing the number of Closing Shares equal to such Investor’s Milestone Overage Number, such Investor shall purchase Pre-Funded Warrants exercisable for a number of Pre-Funded Warrant Shares equal to its Milestone Overage Number. Each Investor shall provide such information to the Company as may be reasonably requested in order to determine the number of shares of Common Stock beneficially owned by such Investor. Notwithstanding anything to the contrary in this Agreement, if the Milestone Closing Trigger is caused by a Price Threshold Waiver, only those Investors who signed the Price Threshold Waiver shall be obligated to participate in the Milestone Closing and the non-signing Investors shall have the right but not the obligation to purchase the number of Closing Shares as determined above in this Section 2.2(a).

6

(b) At the Milestone Closing, each Investor shall pay to an account designated by the Company, by wire transfer of immediately available funds, the amount set forth opposite its name on Exhibit A hereto under the heading “Milestone Closing Subscription Amount” less, if applicable, the product of (x) $0.0001 multiplied by (y) such Investor’s Milestone Overage Number. Subject to receipt of the foregoing payment, the Company will (i) instruct the Transfer Agent to credit each Investor the number of Closing Shares purchased by the Investor pursuant to Section 2.2 hereof, (ii) as promptly as practical, deliver, or cause the Transfer Agent to deliver, written evidence of the issuance to the Investor of such Closing Shares on and as of the Milestone Closing Date, and (iii) if applicable, deliver to such Investor the Pre-Funded Warrants purchased by such Investor at the Milestone Closing.

The issuance and delivery of the Closing Shares does not, and the exercise in full of the Pre-Funded Warrants and the issuance and delivery of the Pre-Funded Warrant Shares thereupon will not, (a) obligate the Company to offer to issue, or issue, shares of Common Stock or other securities to any Person (other than the Investors) pursuant to any preemptive rights, rights of first refusal, rights of participation or similar rights, or (b) result in any adjustment (automatic, at the election of any Person or otherwise) of the exercise, conversion, exchange or reset price under, or any other anti-dilution adjustment pursuant to, any outstanding securities of the Company.

There is no pending or, to the Company’s knowledge, threatened action, suit, proceeding or claim by others: (A) challenging the Company’s rights in or to any Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such action, suit, proceeding or claim; (B) challenging the validity, enforceability or scope of any Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for any such action, suit, proceeding or claim; or (C) asserting that the Company or any of its subsidiaries infringes or otherwise violates, or would, upon the commercialization of any product or service described in the SEC Reports as under development, infringe, misappropriate or violate, any patent, trademark, trade name, service name, copyright, trade secret or other proprietary rights of others, and the Company is unaware of any facts which would form a reasonable basis for any such action, suit, proceeding or claim.

The Company and its subsidiaries and any “employee benefit plan” (as defined under ERISA) established or maintained by the Company, its subsidiaries or, to the knowledge of the Company, its “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or any subsidiary, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Code of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the

12

Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each employee benefit plan established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and, to the Company’s knowledge, nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

3.14 Taxes. The Company and its consolidated subsidiaries have filed all necessary federal, state and foreign income and franchise tax returns or have properly requested extensions thereof and have paid all taxes required to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them except as may be being contested in good faith and by appropriate proceedings, except as would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

3.16 Title. The Company and each of its subsidiaries has good and marketable title to all of the real and personal property and other assets reflected as owned in the financial statements referred to in Section 3.8(b) above (or elsewhere in the SEC Reports), in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, adverse claims and other defects, except where failure to so possess would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. The real property, improvements,

13

equipment and personal property held under lease by the Company or any subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary.

3.17 Insurance. Each of the Company and its subsidiaries is insured by recognized, financially sound and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for their businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and its subsidiaries against theft, damage, destruction, acts of vandalism and earthquakes and policies covering the Company and its subsidiaries for product liability claims and clinical trial liability claims. The Company has no reason to believe that it or any subsidiary will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not reasonably be expected to result in a Material Adverse Effect. Neither of the Company nor any subsidiary has been denied any insurance coverage which it has sought or for which it has applied, except as would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

The Investor acknowledges and agrees that it has been advised to consult legal counsel prior to making any offer, resale, transfer, pledge or disposition of any of the Securities.

In addition, the Securities may contain a legend regarding affiliate status of the Investor, if applicable.

4.12 Access to Information. In making its decision to purchase the Securities, each Investor has relied solely upon independent investigation made by such Investor, upon the SEC Reports and upon the representations, warranties and covenants set forth herein. The Investor acknowledges and agrees that such Investor and its professional advisor(s), if any, have had the opportunity to ask such questions, receive such answers and obtain such information from the Company regarding the Company, its business and the terms and conditions of the offering of the Securities as the Investor and the Investor’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Securities and that the Investor has independently made its own analysis and decision to invest in the Company. Neither such inquiries nor any other due diligence investigation conducted by the Investor shall modify, limit or otherwise affect the Investor’s right to rely on the Company’s representations and warranties contained in this Agreement.

4.13 Certain Trading Activities. Other than consummating the transaction contemplated hereby, the Investor has not, nor has any Person acting on behalf of or pursuant to any understanding with the Investor, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that the Investor was first contacted by the Company or any other Person regarding the transaction contemplated hereby and ending immediately prior to the date of this Agreement. Notwithstanding the foregoing, in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the representation set forth above shall only apply with respect to the portion of the assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement. Furthermore, in the case of an Investor whose investment advisor utilized an information barrier with respect to the information regarding the transactions contemplated hereunder after first being contacted by the Company or its representatives, the representation set forth above shall only apply after the point in time when the portfolio manager who manages such Investor’s assets was informed of the information regarding the transactions contemplated hereunder and, with respect to the Investor’s investment advisor, the representation set forth above shall only apply with respect to any purchases or sales, including Short Sales, of the securities of the Company on behalf of other funds or investment vehicles for which the Investor’s investment advisor is also an investment advisor or sub-advisor after the point in time when the portfolio manager who manages the assets of such other funds or investment vehicles for which the Investor’s investment advisor is also an investment advisor or sub-advisor was informed of the information regarding the transactions contemplated hereunder. Other than to other Persons party to this Agreement and to its advisors and agents who had a need to know such information, the Investor has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

(b) The Company agrees and acknowledges that the Placement Agent may rely on its representations, warranties, agreements and covenants contained in this Agreement and each Investor agrees that the Placement Agent may rely on such Investor’s representations and warranties contained in this Agreement as if such representations and warranties, as applicable, were made directly to the Placement Agent.

(c) Neither the Placement Agent nor any of its Affiliates or representatives (1) shall be liable for any improper payment made in accordance with the information provided by the Company; (2) makes any representation or warranty, or has any responsibilities as to the validity, enforceability accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to the Transaction Agreements or in connection with any of the transactions contemplated therein; or (3) shall be liable (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred upon it by the Transaction Agreements or (y) for anything which any of them may do or refrain from doing in connection with the Transaction Agreements, except in each case for such party’s own gross negligence or willful misconduct.

(d) The Company agrees that the Placement Agent, its affiliates and representatives shall be entitled to (1) rely on, and shall be protected in acting upon, any certificate, instrument, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as the Placement Agent hereunder pursuant to the indemnification provisions set forth in the applicable letter agreement between the Company and the Placement Agent.

8.10 Third Parties. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties to this Agreement any rights, remedies, claims, benefits, obligations or liabilities under or by reason of this Agreement, and no Person that is not a party to this Agreement (including, without limitation, any partner, member, shareholder, director, officer, employee or other beneficial owner of any party to this Agreement, in its own capacity as such or in bringing a derivative action on behalf of a party to this Agreement) shall have any standing as a third party beneficiary with respect to this Agreement or the transactions contemplated hereby. Notwithstanding the foregoing, (i) the Placement Agent is an intended third-party beneficiary of the representations and warranties of the Company and of each Investor set forth in Section 3, Section 4 and Section 6.1(h) and Section 8.9 respectively, of this Agreement and (ii) the Indemnified Persons are intended third-party beneficiaries of Section 5.9.

8.11 Independent Nature of Investors’ Obligations and Right. The obligations of each Investor under this Agreement are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance obligations of any other Investor under this Agreement. Nothing contained herein, and no action taken by any Investor pursuant hereto, shall be deemed to constitute the Investors as, and the Company acknowledges that the Investors do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group, and the Company will not assert any such claim with respect to such obligations or the transactions contemplated by this Agreement. The Company acknowledges and each Investor confirms that it has independently participated in the negotiation of the transaction

34

contemplated hereby with the advice of its own counsel and advisors. Each Investor also acknowledges that Cooley LLP has not rendered legal advice to such Investor. Each Investor 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 Investor to be joined as an additional party in any proceeding for such purpose. The Company has elected to provide all Investors with the same terms and Transaction Agreements for the convenience of the Company and not because it was required or requested to do so by any Investor.

8.12 Headings. The titles, subtitles and headings in this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

8.13 Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile or pdf signature including any electronic signatures complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile or pdf (or other electronic reproduction of a) signature.

8.14 Entire Agreement; Amendments. This Agreement and the other Transaction Agreements (including all schedules and exhibits hereto and thereto) constitute the entire agreement between the parties hereto respecting the subject matter of this Agreement and supersedes all prior agreements, negotiations, understandings, representations and statements respecting the subject matter of this Agreement, whether written or oral. Except for a Price Threshold Waiver, no amendment, modification, alteration, or change in any of the terms of this Agreement shall be valid or binding upon the parties hereto unless made in writing and duly executed by the Company and the Investors. Notwithstanding the foregoing, this Agreement may not be amended and the observance of any term of this Agreement may not be waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. The Company, on the one hand, and each Investor, on the other hand, may by an instrument signed in writing by such parties waive the performance, compliance or satisfaction by such Investor or the Company, respectively, with any term or provision of this Agreement or any condition hereto to be performed, complied with or satisfied by such Investor or the Company, respectively. Notwithstanding the foregoing or anything else herein to the contrary, no amendment, modification, alteration, change or waiver of this Section 8.14 shall be valid without the prior written consent of the Placement Agent, which consent may be granted or withheld in the sole discretion of the Placement Agent.

8.15 Survival. The covenants, representations and warranties made by each party hereto contained in this Agreement shall survive the Closing and the delivery of the Securities in accordance with their respective terms. Each Investor shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

8.16 Contract Interpretation. This Agreement is the joint product of each Investor and the Company and each provision of this Agreement has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.

8.17 Arm’s Length Negotiations. For the avoidance of doubt, the parties acknowledge and confirm that the terms and conditions of the Securities were determined as a result of arm’s-length negotiations.

8.18 Waiver of Conflicts. Each party to this Agreement acknowledges that Cooley LLP (“Cooley”) has acted as counsel solely to the Company with respect to this Agreement and the transactions contemplated hereby (together, the “Financing”), and has negotiated the terms of the Financing solely on behalf of the Company. Cooley may have, in the past, represented and/or may, now or in the future, represent one or more other parties to this Agreement and/or their Affiliates in other matters, including matters that are similar, but not substantially related, to the Financing. The applicable rules of professional conduct require that Cooley inform its clients of these representations and obtain their waivers of the conflicts that may arise from such representations. The Company and each other party to this Agreement hereby (a) acknowledges that such party has been advised about such circumstances and has had an opportunity to ask for additional information, (b) acknowledges that, with respect to the Financing, Cooley has represented solely the Company and no other party, and (c) gives its informed consent to Cooley’s representation of the Company in the Financing and Cooley’s representation of other parties to this Agreement and/or their Affiliates in other matters.
