If a Purchaser effects a transfer of the Registrable Shares in accordance with Section 3.2(k)(ii), the Company shall permit the transfer and shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Purchaser to effect such transfer. Such Purchaser hereby agrees that the removal of the restrictive legend pursuant to this Section 3.2(k)(ii) is predicated upon the Company’s reliance that such Purchaser will sell any such Registrable Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom.

(l)    Immediately prior to each Closing, such Purchaser, together with its affiliates and any other persons acting as a group together with such Purchaser and any of its affiliates, beneficially owned the number of shares of Common Stock set forth on such Purchaser’s Statement of Beneficial Ownership on Schedule 13G.

22.

(m)    If such Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Code), such 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 any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Securities, (b) any foreign exchange restrictions applicable to such purchase or acquisition, (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. Such Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of such Purchaser’s jurisdiction.

(n)    Acknowledgements Regarding Placement Agent by each Purchaser.

(i)    Such Purchaser acknowledges that the Placement Agent is (a) acting as Placement Agent on a “best efforts” basis for the Securities being offered hereby and will be compensated by the Company for acting in such capacity, and (b) acting solely as Placement Agent in connection with the execution, delivery and performance of the Transaction Documents and is not acting as an underwriter or in any other capacity and are not and shall not be construed as a fiduciary for such Purchaser, the Company or any other person or entity in connection with the execution, delivery and performance of the Transaction Documents. Such Purchaser represents that: (i) it was contacted regarding the sale of the Securities by the Placement Agent or the Company (or an authorized agent or representative thereof) with whom such Purchaser entered into a verbal or written confidentiality agreement; and (ii) no Securities were offered or sold to it by means of any form of general solicitation or general advertising as such terms are used in Regulation D of the Securities Act.

(ii)    Such Purchaser represents that it is making this investment based on the results of its own due diligence investigation of the Company, and has not relied on any information or advice furnished by or on behalf of the Placement Agent in connection with the transactions contemplated hereby. Such Purchaser acknowledges that the Placement Agent has not made, and will not make, any representations and warranties with respect to the Company or the transactions contemplated hereby, and such Purchaser will not rely on any statements made by the Placement Agent, orally or in writing, to the contrary.

(o)    Exculpation of the Placement Agents. Such Purchaser agrees for the express benefit of the Placement Agent, their affiliates and its representatives that neither the Placement Agent nor any of its affiliates or any of its representatives: (i) has any duties or obligations other than those specifically set forth in the Engagement Letter; (ii) shall be liable to such Purchaser for any improper payment made in accordance with the information provided by the Company; (iii) makes any representation or warranty, or has any responsibilities as to the validity, accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to this Agreement or the other Transaction Documents or in connection with any of the transactions contemplated hereby and thereby; or (iv) shall be liable to such Purchaser (A) 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 this Agreement or any other Transaction Documents or (B) for anything which any of them may do or refrain from doing in connection with this Agreement or any other Transaction Document.

23.

(p)    Voting of Securities. With respect to the Company’s upcoming special meeting of stockholders to approve the Charter Amendment (the “Special Meeting”), such Purchaser covenants to the Company, severally and not jointly with any other Purchasers, to vote and to cause its affiliates to vote, with respect to all Common Stock and other voting securities of the Company held of record or with respect to which they are entitled to vote, with respect to the Charter Amendment at the Special Meeting. The covenant contained in this Section 3(p) may be enforced solely by the Company and not the other third parties.

4.1    Definitions. For the purpose of this Section 4, the term “Registrable Shares” means the Common Stock issued at a given Closing, as well as the Common Stock underlying any Prefunded Warrants and/or Warrants issued at a given Closing; provided, however, that a security shall cease to be a Registrable Share upon the earliest to occur of the following: (i) a Registration Statement registering such security under the Securities Act has been declared or becomes effective and such security has been sold or otherwise transferred by the holder thereof pursuant to and in a manner contemplated by such effective Registration Statement, (ii) such security is sold pursuant to Rule 144 under circumstances in which any legend borne by such security relating to restrictions on transferability thereof, under the Security Act or otherwise, is removed by the Company, (iii) such security is eligible to be sold pursuant to Rule 144 without condition or restriction, including, without any limitation as to volume of sales, and without the Purchaser complying with any method of sale requirements or notice requirements under Rule 144, or (iv) such security shall cease to be outstanding following its issuance.

4.2    Registration Procedures and Expenses. The Company shall:

(a)    file a resale registration statement (including any preliminary prospectus, final prospectus, exhibit or amendment included in or relating to such registration statements, a “Registration Statement”) with the Commission as soon as practicable, but in no event later than 30 days following each Closing (the “Filing Date”) to register for resale on Form S-3 all of the Registrable Shares then issued or issuable upon conversion of the Securities issued in such Closing (providing for shelf registration of such Registrable Shares under Commission Rule 415). In the event that Form S-3 is not available for the registration of the Registrable Shares, the Company shall register the resale of the Registrable Shares on such other form as is available to the Company;

(b)    use its commercially reasonable efforts to cause the Registration Statement to be declared effective as soon as practicable, and in any event within 90 days following the applicable Closing date (or, in the event the Staff reviews and has written comments to the Registration Statement, within 120 days following the applicable Closing date) (the earlier of the foregoing or the applicable date set forth in Section 4.2(g), the “Effectiveness Deadline”), such efforts to include, without limiting the generality of the foregoing, preparing and filing with the Commission any financial statements or other information that is required to be filed prior to the effectiveness of the Registration Statement;

24.

(c)    not less than five Trading Days prior to the filing of a Registration Statement or any related prospectus or any amendment or supplement thereto, furnish via email to those Purchasers who have supplied the Company with email addresses copies of all such documents proposed to be filed, which documents (other than any document that is incorporated or deemed to be incorporated by reference therein) will be subject to the review of such Purchasers. The Company shall reflect in each such document when so filed with the Commission such comments regarding the Purchasers and the plan of distribution as the Purchasers may reasonably and promptly propose no later than three Trading Days after the Purchasers have been so furnished with copies of such documents as aforesaid.

(d)    promptly prepare and file with the Commission such amendments and supplements to such Registration Statements and the prospectus used in connection therewith as may be necessary to keep such Registration Statements continuously effective and free from any material misstatement or omission to state a material fact therein until termination of such obligation as provided in Section 4.7 below, subject to the Company’s right to suspend pursuant to Section 4.6;

(e)    furnish to the Purchasers such number of copies of prospectuses in conformity with the requirements of the Securities Act and such other documents as the Purchasers may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Shares by the Purchasers;

(f)    file such documents as may be required of the Company for normal securities law clearance for the resale of the Registrable Shares in such states of the United States as may be reasonably requested by the Purchasers and use its commercially reasonable efforts to maintain such blue sky qualifications during the period the Company is required to maintain effectiveness of the Registration Statements; provided, however, that the Company shall not be required in connection with this Section 4.2(f) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented;

(g)    upon notification by the Commission that a Registration Statement will not be reviewed or is not subject to further review by the Commission, the Company shall within two Trading Days following the date of such notification request acceleration of such Registration Statement (with the requested effectiveness date to be not more than two Trading Days later);

(h)    upon notification by the Commission that that the Registration Statement has been declared effective by the Commission, the Company shall file the final prospectus under Rule 424 of the Securities Act (“Rule 424”) within the applicable time period prescribed by Rule 424;

(i)    advise the Purchasers promptly (and in any event within two Trading Days thereof):

(i)    of the effectiveness of the Registration Statement or any post-effective amendments thereto;

25.

(ii)    of any request by the Commission for amendments to the Registration Statement or amendments to the prospectus or for additional information relating thereto;

(iii)    of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable Shares for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes; and

(iv)    of the existence of any fact and the happening of any event that makes any statement of a material fact made in the Registration Statement, the prospectus and amendment or supplement thereto, or any document incorporated by reference therein, untrue, or that requires the making of any additions to or changes in the Registration Statement or the prospectus in order to make the statements therein not misleading;

(j)    cause all Registrable Shares to be listed on each securities exchange, if any, on which equity securities by the Company are then listed;

(k)    bear all expenses in connection with the procedures in paragraphs (a) through (l) of this Section 4.2 and the registration of the Registrable Shares on such Registration Statement and the satisfaction of the blue sky laws of such states; and

(l)    not, from the date hereof until the effective date of the Registration Statement relating to the Initial Closing Shares, prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than any registration statement or post-effective amendment to a registration statement (or supplement thereto) related to the Company’s employee benefit plans registered on Form S-8).

4.3    Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement. Subject to Section 4.4, if either: (a) a Registration Statement covering all of the Registrable Shares required to be covered thereby and required to be filed by the Company pursuant to this Agreement following a given Closing is: (i) not filed with the Commission on or before a Filing Date (a “Filing Failure”), or (ii) not declared effective by the Commission on or before an Effectiveness Deadline (an “Effectiveness Failure”), or (b) on any day after effectiveness, sales of all of the Registrable Shares required to be included on such Registration Statement cannot be made (other than during an Allowable Grace Period) pursuant to such Registration Statement (a “Maintenance Failure”), then, in satisfaction of the damages to any holder of Registrable Shares by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock, the Company shall pay to each Purchaser of Registrable Shares relating to such Registration Statement an amount in cash equal to 1.0% of such Purchaser’s aggregate purchase price then paid through each applicable closing relating to the applicable Registrable Shares on each of the following dates: (x) the day of a Filing Failure and on every thirtieth day (prorated for periods totaling less than 30 days) thereafter until such Filing Failure is cured; (y) the day of an Effectiveness Failure and on every thirtieth day (prorated for periods totaling less than 30 days) thereafter until such Effectiveness Failure is cured; and (z) the initial day of a Maintenance Failure and on every thirtieth day (prorated for periods totaling less than 30

26.

days) thereafter until such Maintenance Failure is cured. The payments to which a holder shall be entitled pursuant to this Section 4.3 are referred to herein as “Registration Delay Payments”; provided that in no event shall the aggregate Registration Delay Payments accruing under this Section 4.3 exceed 10% of a Purchaser’s aggregate purchase price then paid at a given Closing relating to the applicable Registrable Shares. The first such Registration Delay Payment shall be paid within three business days after the event or failure giving rise to such Registration Delay Payment occurred and all other Registration Delay Payments shall be paid on the earlier of (I) the last day of the calendar month during which such Registration Delay Payments are incurred and (II) the third Business Day after the event or failure giving rise to the Registration Delay Payments is cured.

4.4    Rule 415; Cutback.

If at any time the staff of the Commission (“Staff”) takes the position that the offering of some or all of the Registrable Shares in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires any Purchaser to be named as an “underwriter,” the Company shall (in consultation with legal counsel to the Purchaser) use its commercially reasonable efforts to persuade the Commission that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Purchasers is an “underwriter.” In the event that, despite the Company’s commercially reasonable efforts (including incorporating comments from the Purchasers and their counsel on any response letters to Commissions comments, so long as such comments are provided without unreasonable delay) and compliance with the terms of this Section 4.4, the Staff refuses to alter its position, the Company shall (i) remove from the Registration Statement such portion of the Registrable Shares (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Shares as the Staff may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Purchaser as an “underwriter” in such Registration Statement without the prior written consent of such Purchaser. Any cutback imposed on the Purchasers pursuant to this Section 4.3 shall be allocated among the Purchasers on a pro rata basis, unless the SEC Restrictions otherwise require or provide or the Purchasers holding a majority of the Registrable Shares otherwise agree. No liquidated damages shall accrue under Section 4.3 as to any Cut Back Shares until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date” of such Cut Back Shares). From and after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this Section 4 shall again be applicable to such Cut Back Shares; provided, however, that (x) the Filing Date for the Registration Statement including such Cut Back Shares shall be 10 Trading Days after such Restriction Termination Date, and (y) the Effectiveness Deadline with respect to such Cut Back Shares shall be the 90^th day immediately after the Restriction Termination Date or the 120^th day if the Staff reviews such Registration Statement (but in any event no later than three Trading Days from the Staff indicating it has no further comments on such Registration Statement).

27.

4.5    Indemnification.

(a)    The Company agrees to indemnify and hold harmless each Purchaser and its affiliates, partners, members, officers, directors, agents and representatives, and each person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act or Section 20 the Exchange Act (each, a “Purchaser Party” and collectively the “Purchaser Parties”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages or liabilities (collectively, “Losses”) to which they may become subject (under the Securities Act or otherwise) insofar as such Losses (or actions or proceedings in respect thereof) arise out of, or are based upon, any material breach of this Agreement by the Company or any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or arise out of any failure by the Company to fulfill any undertaking included in the Registration Statement and the Company will, as incurred, reimburse the Purchaser Parties for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such Loss arises out of, or is based upon: (i) an untrue statement or omission or alleged untrue statement or omission made in such Registration Statement in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Purchaser specifically for use in preparation of the Registration Statement; or (ii) any breach of this Agreement by such Purchaser; provided further, however, that the Company shall not be liable to any Purchaser Party (or any partner, member, officer, director or controlling person of the Purchasers) to the extent that any such Loss is caused by an untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus if either (i) (A) such Purchaser failed to send or deliver a copy of the final prospectus with or prior to, or such Purchaser failed to confirm that a final prospectus was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the sale by such Purchaser to the person asserting the claim from which such Loss resulted and (B) the final prospectus corrected such untrue statement or omission, (ii) (X) such untrue statement or omission is corrected in an amendment or supplement to the prospectus and (Y) having previously been furnished by or on behalf of the Company with copies of the prospectus as so amended or supplemented or notified by the Company that such amended or supplemented prospectus has been filed with the Commission, in accordance with Rule 172 of the Securities Act, such Purchaser thereafter fails to deliver such prospectus as so amended or supplemented, with or prior to or a Purchaser fails to confirm that the prospectus as so amended or supplemented was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the sale by such Purchaser to the person asserting the claim from which such Loss resulted or (iii) such Purchaser sold Registrable Shares in violation of such Purchasers’ covenants contained in Section 3.2 of this Agreement.

(b)    Each Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and its officers, directors, affiliates, agents and representatives and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each a “Company Party” and collectively the “Company Parties”), from and against any Losses to which the Company Parties may become subject (under the Securities Act or otherwise), insofar as such Losses(or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement of a material fact contained in the

28.

Registration Statement (or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading in each case, on the effective date thereof), if, and only to the extent, such untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of such Purchaser specifically for use in preparation of the Registration Statement, and each Purchaser, severally and not jointly, will reimburse each Company Party for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that in no event shall any indemnity under this Section 4.5(b) be greater in amount than the dollar amount of the net proceeds received by such Purchaser upon its sale of the Registrable Shares included in the Registration Statement giving rise to such indemnification obligation.

(c)    Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 4.5, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person and such indemnifying person shall have been notified thereof, such indemnifying person shall be entitled to participate therein, and, to the extent that it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate in the reasonable judgment of the indemnified person for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, further, that no indemnifying person shall be responsible for the fees and expense of more than one separate counsel for all indemnified parties. The indemnifying party shall not settle an action without the consent of the indemnified party, which consent shall not be unreasonably withheld.

(d)    If after proper notice of a claim or the commencement of any action against the indemnified party, the indemnifying party does not choose to participate, then the indemnified party shall assume the defense thereof and upon written notice by the indemnified party requesting advance payment of a stated amount for its reasonable defense costs and expenses, the indemnifying party shall advance payment for such reasonable defense costs and expenses (the “Advance Indemnification Payment”) to the indemnified party. In the event that the indemnified party’s actual defense costs and expenses exceed the amount of the Advance Indemnification Payment, then upon written request by the indemnified party, the indemnifying party shall reimburse the indemnified party for such difference; in the event that the Advance Indemnification Payment exceeds the indemnified party’s actual costs and expenses, the indemnified party shall promptly remit payment of such difference to the indemnifying party.

29.

(e)    If the indemnification provided for in this Section 4.5 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other, as well as any other relevant equitable considerations; provided, that in no event shall any contribution by an indemnifying party hereunder be greater in amount than the dollar amount of the proceeds received by such indemnifying party upon the sale of such Registrable Shares.

4.6    Prospectus Suspension. Each Purchaser acknowledges that there may be times when the Company must suspend the use of the prospectus forming a part of the Registration Statement until such time as an amendment to the Registration Statement has been filed by the Company and declared effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act. Each Purchaser hereby covenants that it will not sell any Registrable Shares pursuant to said prospectus during the period commencing at the time at which the Company gives the Purchasers notice of the suspension of the use of said prospectus and ending at the time the Company gives the Purchasers notice that the Purchasers may thereafter effect sales pursuant to said prospectus; provided, that such suspension periods shall in no event exceed 20 days in any 12-month period (an “Allowable Grace Period”) and that, in the good faith judgment of the Board of Directors, the Company would, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating thereto, in either case the disclosure of which would reasonably be expected to have a material adverse effect upon the Company or its stockholders.

4.7    Termination of Obligations. The obligations of the Company pursuant to Section 4.2 hereof shall cease and terminate, with respect to any Registrable Shares, upon the earlier to occur of (a) such time such Registrable Shares have been resold, or (b) such time as such Registrable Shares no longer remain Registrable Shares pursuant to Section 4.1 hereof.

4.8    Reporting Requirements.

(a)    With a view to making available the benefits of certain rules and regulations of the Commission that may at any time permit the sale of the Resistrable Shares to the public without registration or pursuant to a registration statement on Form S-3, the Company agrees to use:

(i)    make and keep public information available, as those terms are understood and defined in Rule 144;

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

(iii)    so long as a Purchaser owns Registrable Shares, to furnish to such Purchaser upon request (A) a written statement by the Company as to whether it is in compliance with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, or whether

30.

it is qualified as a registrant whose securities may be resold pursuant to Commission Form S-3, (B) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company and (C) such other information as may be reasonably requested to permit the Purchaser to sell such securities pursuant to Rule 144.

4.9    Blue Sky. The Company shall obtain and maintain all necessary blue sky law permits and qualifications, or secured exemptions therefrom, required by any state for the offer and sale of Registrable Shares.

5.1    Integration. Except as contemplated by the terms of this Agreement, the Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities such that the rules of Nasdaq would require shareholder approval of this transaction prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

5.2    Securities Laws Disclosure; Publicity. The Company shall: (a) issue a press release disclosing the material terms of the transactions contemplated hereby promptly following the execution and delivery hereof (the “Press Release”), and (b) by 5:30 p.m. (New York City time) on the fourth Trading Day following the date hereof, file a Current Report on Form 8-K disclosing the material terms of the transactions contemplated hereby, in each case which shall have been previously reviewed by counsel for the Placement Agent (the “Form 8-K”). From and after the issuance of the Press Release, no Purchaser shall be in possession of any material, non-public information received from the Company or any of their respective officers, directors or employees that is not disclosed in the Press Release, other than certain of the Non-Public Information (as defined in Section 5.3). Subject to the foregoing, neither the Company nor any Purchaser shall issue any press releases or any other public statements with respect to the transactions contemplated hereby except as may be reviewed and approved by the Company and counsel to the Placement Agent; provided, however, that the Company shall be entitled, without the prior approval of any Purchaser, to make any press release or other public disclosure as is required by applicable law and regulations.

5.3    Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents (“Non-Public Information”), the Company covenants and agrees that neither it nor any of its officers, directors, employees or agents acting on its behalf will provide any Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information. The Company covenants and agrees that it will publicly disclose the Non-Public Information by no later than one Trading Day from the date hereof.

5.4    Use of Proceeds. The Company will use the net proceeds received from the sale of the Securities for general corporate purposes, which may include working capital, capital expenditures, research and development expenditures, clinical trial expenditures, commercial expenditures and milestone payments under in-license agreements.

The Company covenants and agrees that as soon as reasonably practicable, but in any event no later than August 11, 2023, the Company shall present a proposal seeking approval of the Charter Amendment (with the recommendation of the Company’s Board of Directors to vote in favor of such proposal) and shall use reasonable best efforts to secure such approval at such meeting (and any subsequent meeting(s)). In the event that the Company does not successfully obtain approval of the Charter Amendment by the foregoing deadline, then the Company will convene subsequent stockholder meetings at least once every 180 days until it has succeeded in obtaining such approval. Upon receipt of stockholder approval, the Company shall promptly file the Charter Amendment.

5.6    Reservation of Common Stock. As of the date hereof, the Company has reserved and shall continue to reserve and keep available at all times, free of preemptive rights, the maximum number of shares of Common Stock permitted to be reserved, prior to effectiveness of the Charter Amendment, for the purpose of enabling the Company to issue the Common Stock underlying the Prefunded Warrants (such number of shares of Common Stock, the “Initial Reserve”). Upon effectiveness of the Charter Amendment, the Company shall reserve and shall continue to reserve and keep available at all times, free of preemptive rights, an additional number of shares of Common Stock representing the number of shares required in addition to the Initial Reserve to be sufficient for the purpose of enabling the Company to issue all Securities issuable at the Second Closing.

5.7    Nasdaq Listing. The Company shall prepare and file with Nasdaq a Notification of Listing of Additional Shares covering all Registrable Shares potentially issuable hereunder and shall cause all the Registrable Shares to be approved for listing on Nasdaq as promptly as possible thereafter.

5.8    Subsequent Equity Sales. From the date hereof until ninety (90) days after the Initial Closing Date, neither the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents. Notwithstanding the foregoing, this Section 5.9 shall not apply in respect of an Exempt Issuance.

5.9    Preemptive Right. For a period of five years from the Initial Closing Date, the Purchasers shall have the right to subscribe for their pro rata share (determined on an as-converted and fully-diluted basis, without regard to beneficial ownership limitations) of all future offerings of equity securities (including derivative securities that are convertible, exchangeable or exercisable for Common Stock), but excluding any Exempt Issuances. For any offering of securities subject to this Section 5.9, the Purchasers shall be provided with written notice of the proposed offering and the proposed terms at least five Trading Days prior to pricing. The Purchasers shall then have three Trading Days to indicate their interest in subscribing for the securities to be offered and sold in such offering(s).

6.1    Termination. This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Initial

32.

Closing has not been consummated within 10 calendar days from the Effective Date through no fault of such Purchaser; provided, however, that no such termination will affect the right of any party to sue for any breach by the other party (or parties).

6.2    Fees and Expenses. Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. Notwithstanding the foregoing, the Company shall pay: (i) the reasonable fees and expenses of Biotechnology Value Fund (“BVF”) and its counsel in connection with the transactions contemplated hereunder, including the registration of the Registrable Shares (such expenses not to exceed $100,000 in the aggregate), and (ii) all transfer agent fees, stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the Purchasers.

6.3    Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such subject matter, which the parties acknowledge have been merged into such documents, exhibits and schedules.

6.4    Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective upon actual receipt via mail, courier or confirmed email by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages attached hereto.

6.5    Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by (a) the Company and (b) Purchasers holding at least a majority of the Securities sold in the Initial Closing (as a single class on an as-converted to Common Stock basis and without regard to any beneficial ownership limitations) and then-held by a Purchaser or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought.
