Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Securities.

(g) Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and the Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by or on behalf of such Purchaser or its representatives or counsel shall modify, amend or affect such Purchaser’s right to rely on the truth, accuracy and completeness of the SEC Reports and the Company’s representations and warranties contained in the Transaction Documents. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed decision with respect to its acquisition of the Securities.

(h) Certain Trading Activities. Other than with respect to the transactions contemplated herein, since the time that such Purchaser was first contacted by the Company, the Placement Agents or any other Person regarding the transactions contemplated hereby, the Purchaser has not, directly or indirectly, effected or agreed to effect any Short Sales. Notwithstanding the foregoing, (i) in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets, the foregoing representation shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement and (ii) and in the case of a Purchaser whose investment adviser utilized an information barrier with respect to the information regarding the transactions contemplated hereunder after first being contacted by the Company or such other Person representing the Company, the representation set forth above shall only apply after the point in time when the portfolio manager who manages such Purchaser’s assets was informed of the information regarding the transactions contemplated hereunder and, with respect to the Purchaser’s investment adviser, 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 Purchaser’s investment adviser is also an investment adviser or sub-adviser after the point in time when the portfolio manager who manages the assets of such other funds or investment vehicles for which the Purchaser’s investment adviser is also an investment adviser or sub-adviser was informed of the information regarding the transactions contemplated hereunder. Other than to other Persons party to this Agreement and to the Purchaser’s representatives or agents, including, but not limited to, the Purchaser’s legal, tax and investment advisors, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future.

(i) Brokers and Finders. No Person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest or claim against or upon the Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Purchaser. No Purchaser shall have any obligation with respect to any fees, or with respect to any claims made by or on behalf of other Persons for fees, in each case of the type contemplated by this Section 3.2(i) that may be due in connection with the transactions contemplated by this Agreement or the Transaction Documents.

(j) Independent Investment Decision. Such Purchaser has independently evaluated the merits of its decision to purchase Securities pursuant to the Transaction Documents, and such Purchaser confirms that it has not relied on the advice of any other Purchaser’s business and/or legal counsel in making such decision. Such Purchaser understands that nothing in this Agreement or any other materials presented by or on behalf of the Company to the Purchaser in connection with the purchase of the Securities constitutes legal, tax or investment advice. Such Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities. Such Purchaser understands that the Placement Agents have acted solely as the agent of the Company in this placement of the Securities and such Purchaser has not relied on the business or legal advice of the Placement Agents or any of their agents, counsel or Affiliates in making its investment decision hereunder, and confirms that none of such Persons has made any representations or warranties to such Purchaser in connection with the transactions contemplated by the Transaction Documents.

(k) Reliance on Exemptions. Such Purchaser understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Purchaser’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the Securities.

(l) No Governmental Review. Such Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(m) Regulation M. Such Purchaser is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of Securities and other activities with respect to the Securities by the Purchasers.

(n) Beneficial Ownership. The purchase by such Purchaser of the Securities issuable to it at the Closing will not result in such Purchaser (individually or together with any other Person with whom such Purchaser has identified, or will have identified, itself as part of a “group” in a public filing made with the Commission involving the Company’s securities) acquiring, or obtaining the right to acquire, beneficial ownership in excess of 19.9% of the outstanding shares of Common Stock or the voting power of the Company on a post transaction basis that assumes that such Closing shall have occurred. Such Purchaser does not presently intend to, alone or together with others, make a public filing with the Commission to disclose that it has (or that it together with such other Persons have) acquired, or obtained the right to acquire, as a result of such Closing when added to any other securities of the Company that it or they then own or have the right to acquire, beneficial ownership in excess of 19.9% of the outstanding shares of Common Stock or the voting power of the Company on a post transaction basis that assumes that such Closing shall have occurred. The foregoing representation and warranty in this Section 3.2(n) is not made by TAS Partners LLC or any of its Affiliates.

(o) Residency. Such Purchaser’s residence (if an individual) or offices in which its investment decision with respect to the Securities was made (if an entity) are located at the address set forth under such Purchaser’s name on Annex A hereto or as otherwise disclosed to the Company in writing (which writing may be an email from a Purchaser or its agent) or as otherwise specified below its address on Annex A hereto.

The Company and each of the Purchasers acknowledge and agree that no party to this Agreement has made or makes any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Article 3 and the Transaction Documents.

4.1 Transfer Restrictions.

(a) Compliance with Laws. Notwithstanding any other provision of this Article 4, each Purchaser covenants that the Securities and Conversion Shares may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, and in compliance with any applicable U.S. state and federal securities laws. In connection with any transfer of the Securities or the Conversion Shares other than (i) pursuant to an effective registration statement, (ii) to the Company, (iii) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the securities may be sold pursuant to such rule), or (iv) in connection with a bona fide pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities or Conversion Shares under the Securities Act and, as a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and the Registration Rights Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement with respect to such transferred Securities or Conversion Shares.

(b) Legends. Book-entry statements evidencing the Securities and any Conversion Shares shall bear any legend as required by the “blue sky” Laws of any state and a restrictive legend in substantially the following form:

THE OFFER AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE TO WHICH THIS CONFIRMATION RELATES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE 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 AND ITS TRANSFER AGENT SHALL BE ENTITLED TO REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND THE TRANSFER AGENT THAT SUCH REGISTRATION IS NOT REQUIRED. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

The Company acknowledges and agrees that a Purchaser may from time to time pledge, and/or grant a security interest in, some or all of the legended Securities or Conversion Shares in connection with applicable securities laws, pursuant to a bona fide margin agreement in compliance with a bona fide margin loan. Such a pledge would not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion shall be required in connection with a subsequent transfer or foreclosure following default by the Purchaser transferee of the pledge. No notice shall be required of such pledge, but Purchaser’s transferee shall promptly notify the Company of any such subsequent transfer or foreclosure. Each Purchaser acknowledges that the Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Securities or Conversion Shares or for any agreement, understanding or arrangement between any Purchaser and its pledgee or secured party. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities or Conversion Shares may reasonably request in connection with a pledge or transfer of the Securities or Conversion Shares, as applicable, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of selling stockholders thereunder. Each Purchaser acknowledges and agrees that, except as otherwise provided in Section 4.1(c), any Securities or Conversion Shares subject to a pledge or security interest as contemplated by this Section 4.1(b) shall continue to bear the legend set forth in this Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(b).

(c) Removal of Legends. The legend set forth in Section 4.1(b) above shall be removed and the Company shall cause its Transfer Agent to issue book-entry statements without such legend or any other legend to the holder of the applicable Securities or Conversion Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”) (i) upon effectiveness of the initial Registration Statement covering the resale of the Common Shares and the Conversion Shares, and upon request of a Purchaser (including, for the avoidance of doubt, by providing the Transfer Agent with an opinion of a counsel or other documentation acceptable to the Transfer Agent permitting such removal) and receipt of a representation letter from the Purchaser in the form attached hereto as Exhibit H, (ii) upon receipt of notice from a Purchaser stating that the applicable Securities or Conversion Shares have been sold pursuant to an effective Registration Statement, (iii) if such Securities or Conversion Shares are sold or transferred pursuant to Rule 144, or (iv) if such Securities or Conversion Shares are eligible for sale under Rule 144, without the requirement for the Company to be compliance with the current public information required under Rule 144 as to such Securities or Conversion Shares and without volume or manner-of-sale restrictions. Book-entry notations for the Securities or Conversion Shares subject to legend removal hereunder may be transmitted by the Company’s Transfer Agent to such Purchaser by crediting the DTC account of such Purchaser’s broker or other DTC participant as directed by such Purchaser, and the Company shall provide any legal opinions, or other information acceptable to the Transfer Agent in lieu of legal opinions, required by the Transfer Agent in connection with any such legend removal.

(d) Irrevocable Transfer Agent Instructions. The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 4.1(d) (or instructions that are consistent therewith) will be given by the Company to its Transfer Agent in connection with this Agreement, and that the Securities and Conversion Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction Documents and applicable law. The Company acknowledges that a breach by it of its obligations under this Section 4.1(d) will cause irreparable harm to a Purchaser. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 4.1(d) may be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.1(d) that a Purchaser shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing irreparable harm or economic loss and without any bond or other security being required.

4.2 Furnishing of Information. In order to enable the Purchasers to sell the Securities and Conversion Shares under Rule 144, until such time as Purchaser may sell the Securities and Conversion Shares without limitation under Rule 144 (including without the need for current public information required by Rule 144(i)(2)), the Company shall use its commercially reasonable efforts to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act and, if during such period, the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities and Conversion Shares under Rule 144.

4.3 Integration. The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities or the Conversion Shares in a manner that would require the registration under the Securities Act of the sale of the Securities or the Conversion Shares to the Purchasers, or that will be integrated with the offer or sale of the Securities or the Conversion Shares for purposes of the rules and regulations of any Trading Market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

4.4 Securities Laws Disclosure; Publicity. By no later than 9:00 a.m., New York City time, on the Trading Day immediately following the date hereof (provided that, if this Agreement is executed between midnight and 9:00 a.m., New York City time on any Trading Day, no later than 9:01 a.m. on the date hereof) (the “Disclosure Deadline”), the Company shall (a) issue a press release (the “Press Release”) reasonably acceptable to the Placement Agents disclosing (x) all material terms of the transactions contemplated hereby and by the other Transaction Documents and (y) all other material non-public information pertaining to the Company and its operations, to the extent such information has been provided or made available to any of the Purchasers prior to the issuance of the Press Release and (b) file a Current Report on Form 8-K with the Commission describing the terms of the Transaction Documents (and including as exhibits to such Current Report on Form 8-K the material Transaction Documents, the Press Release, and the press release disclosing the Clinical Information); provided that the Press Release shall not publicly disclose the name of any Purchaser or investment adviser of any Purchaser, or include the name of any Purchaser or an Affiliate of any Purchaser without the prior written consent of such Purchaser. In addition, notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser or investment adviser of any Purchaser, or include the name of any Purchaser or an Affiliate of any Purchaser without the prior written consent of such Purchaser (i) in any press release or marketing materials or (ii) in any filing with the Commission or any regulatory agency or Trading Market, except as required by U.S. federal securities law (A) in connection with any registration statement contemplated by the Registration Rights Agreement (which shall be subject to review and comment of the Purchasers pursuant to the terms of the Registration Rights Agreement) or the filing of final Transaction Documents (including signature pages thereto) with the Commission and (B) to the extent such disclosure is required by law, request of the Commission’s staff or Trading Market regulations, in which case the Company shall provide the Purchasers with prior written notice of and a reasonable opportunity to review such disclosure permitted under this subclause (ii). 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, any Subsidiary or any of their respective officers, directors, employees or agents, including the Placement Agents. Each Purchaser, severally and not jointly with any other Purchaser, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the Press Release, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information provided in connection therewith; provided, however, that any disclosure may be made by the Purchaser to the Purchaser’s representatives or agents, including, but not limited to, the Purchaser’s legal, tax and investment advisors.

4.5 Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement or Law (including Section 203 of the Delaware General Corporation Law) in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, in either case solely by virtue of receiving Securities or Conversion Shares under the Transaction Documents.

4.6 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, including this Agreement, or as expressly required by any applicable securities law, the Company covenants and agrees that neither it, nor any other Person acting on its behalf, will provide any Purchaser or its agents or counsel with any information regarding the Company that the Company believes constitutes material non-public information without the express written (email being sufficient) consent of such Purchaser, (i) unless prior thereto such Purchaser shall have committed to customary obligations regarding the confidentiality and use of such information and (ii) except in the case of material, nonpublic information provided to an observer of the Board of Directors or member of the Board of Directors who is affiliated with such Purchaser. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

4.7 Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder for working capital and general corporate purposes.

4.8 Principal Trading Market Listing. The Company shall use its reasonable best efforts to take all steps necessary to cause the Common Shares and the Conversion Shares to be approved for listing on the Principal Trading Market as promptly as possible.

4.9 Form D; Blue Sky. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon the written request of any Purchaser. The Company, on or before the Closing Date, shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the Purchasers under applicable securities or “blue sky” Laws of the states of the United States (or to obtain an exemption from such qualification) and shall provide evidence of such actions promptly upon the written request of any Purchaser.

4.10 Short Sales After the Date Hereof. Such Purchaser shall not 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 the earlier of such time as (i) the transactions contemplated by this Agreement are first publicly announced as required by and described in Section 4.4 or (ii) this Agreement is terminated in full pursuant to Section 6.18.

4.11 Beneficial Ownership Limitation. Notwithstanding anything to the contrary set forth in the Certificate of Designation, the Company shall not effect any conversion of any share of Series B Preferred Stock, and a Purchaser shall not have the right to convert any portion of its Series B Preferred Stock, to the extent that, after giving effect to such attempted conversion set forth on an applicable Notice of Conversion (as defined in the Certificate of Designation) with respect to the Series B Preferred Stock, such Purchaser (or any of such Purchaser’s Affiliates or any other Person who would be a beneficial owner of Common Stock beneficially owned by the Purchaser for purposes of Section 13(d) or Section 16 of the Exchange Act and the applicable rules and regulations of the Commission, including any “group” of which the Purchaser is a member (the foregoing, “Attribution Parties”)) would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Purchaser and its Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock subject to the Notice of Conversion or the Automatic Conversion (as defined in the Certificate of Designation), as applicable, with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Series B Preferred Stock beneficially owned by such Purchaser or any of its Attribution Parties, and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Purchaser or any of its Attribution Parties that are subject to and would exceed a limitation on conversion or exercise similar to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this Section 4.11, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the applicable rules and regulations of the Commission, and the terms “beneficial ownership” and “beneficially own” have the meanings ascribed to such terms therein. In addition, for purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable rules and regulations of the Commission. For purposes of this Section 4.11, in determining the number of outstanding shares of Common Stock, a Purchaser may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual filing with the Commission, as the case may be, (ii) a more recent public announcement by the Company that is filed with the Commission, or (iii) a more recent notice by the Company or the Company’s transfer agent to the Purchaser setting forth the number of shares of Common Stock then outstanding. For any reason at any time, upon the written request of a Purchaser (which may be by e-mail), the Company shall, within two Trading Days of such request, confirm in writing to such Purchaser (which may be by e-mail) the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Company, including Series B Preferred Stock, by such Purchaser or its Attribution Parties since the date as of which such number of outstanding shares of Common Stock was last publicly reported or confirmed to the Purchaser. The “Beneficial Ownership Limitation” shall initially be set at the discretion of each Purchaser to a percentage between 0% and 19.9% of the number of shares of the Common Stock outstanding or deemed to be outstanding as of the applicable measurement date, and such percentage shall be set at 9.9% for any Purchaser that does not make such designation on Annex A hereto. The Company shall be entitled to rely on representations made to it by any Purchaser in any Notice of Conversion regarding its Beneficial Ownership Limitation. Notwithstanding the foregoing, by written notice to the Company, (i) any Purchaser may reset the Beneficial Ownership Limitation percentage to a higher percentage, not to exceed 19.9%, which increase will not be effective until the 61st day after such written notice is delivered to the Company, and (ii) any Purchaser may reset the Beneficial Ownership Limitation percentage to a lower percentage provided that such decrease shall not become effective until the later of (x) 5:00 p.m. New York City time on the third Business Day after the date of the Requisite Stockholder Approval and (y) if the Requisite Stockholder Approval is not obtained within six months after the initial issuance of the Series B Preferred Stock, the date that is three Business Days after the date that is six months after the initial issuance of the Series B Preferred Stock. Upon such a change by a Purchaser of the Beneficial Ownership Limitation, not to exceed 19.9%, the Beneficial Ownership Limitation may not be further amended by such Purchaser without first providing the minimum notice required by this Section 4.11. Notwithstanding the foregoing, at any time following notice of a Fundamental Transaction (as defined in the Certificate of Designation), the Purchaser may waive and/or change the Beneficial Ownership Limitation effective immediately upon written notice to the Company and may reinstitute a Beneficial Ownership Limitation at any time thereafter effective immediately upon written notice to the Company. The provisions of this Section 4.11 shall be construed, corrected and implemented in a manner so as to effectuate the intended Beneficial Ownership Limitation herein contained and the shares of Common Stock underlying the Preferred Shares in excess of the Beneficial Ownership Limitation shall not be deemed to be beneficially owned by the Purchaser for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. Notwithstanding the foregoing, the Beneficial Ownership Limitation shall not apply to TAS Partners LLC or any of its Affiliates.

4.12 Requisite Stockholder Approval. The Company shall use its best efforts to obtain stockholder approval of the conversion of all issued and outstanding Series B Preferred Stock into shares of Common Stock in accordance with the Nasdaq Stock Market Rules (the “Requisite Stockholder Approval”) at a special meeting of stockholders (the “Special Meeting”), which such Special Meeting shall be held no later than October 31, 2024. The Company shall use its reasonable best efforts to solicit its stockholders’ approval of such resolution and to cause the Board of Directors to recommend to the stockholders that they approve such resolution. If the Requisite Stockholder Approval is not obtained at the Special Meeting, the Company shall cause an additional meeting of the Company’s stockholders to be held within 90 days from the date of the Special Meeting (the “Extended Stockholder Approval Period”). If the Requisite Stockholder Approval is not obtained within the Extended Stockholder Approval Period, then the Company shall convene additional stockholder meetings every 90 days thereafter until the Requisite Stockholder Approval is obtained.

4.13 Conversion Procedures. The form of Notice of Conversion included in the Certificate of Designation sets forth the totality of the procedures required of the Purchasers in order to convert the Preferred Shares. Without limiting the preceding sentence, no ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be required in order for the registered holder thereof to convert the Preferred Shares. No additional legal opinion, other information or instructions shall be required of a Purchaser to convert its Preferred Shares. The Company shall honor conversions of the Preferred Shares and shall deliver Conversion Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

4.14 Indemnification of Purchasers. Subject to the provisions of this Section 4.14, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees, investment advisers and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners, investment advisers or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (i) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (ii) any Proceeding instituted against a Purchaser in any capacity, or any Purchaser Party, by any stockholder of the Company who is not an Affiliate of such Purchaser seeking indemnification, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Purchaser’s representations, warranties or covenants under the Transaction Documents, or any agreements or understandings such Purchaser may have with any such stockholder or any violations by the Purchaser of state or federal securities Laws or any conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). Promptly after receipt by any such Person (the “Indemnified Person”) of notice of any demand, claim or circumstances that would or may give rise to a claim or the commencement of any Proceeding or investigation in respect of which indemnity may be sought pursuant to this Section 4.14, such Indemnified Person shall promptly notify the Company in writing and, (1) with respect to claims relating to clause (i) above, the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all reasonable and documented fees and expenses relating to such Proceeding or investigation and (2) with respect to claims relating to clause (ii) above, the Indemnified Person shall have the right to assume the defense thereof or, in its sole discretion, consent to the assumption of defense by the Company, and shall so inform the Company in such notice; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is actually and materially prejudiced by such failure to notify. In any such proceeding under clause (i) or, if the Indemnified Person has consented to the Company assuming defense of a proceeding under clause (ii), any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (x) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; (y) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (z) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. In the event of the circumstances described in the foregoing clause (z), if the Indemnified Person notifies the Company in writing that such Indemnified Person elects to employ separate counsel at the expense of the Company, then the Company shall not have the right to assume the defense of such claim on behalf of such Indemnified Person. The Company shall not be liable for any settlement of any proceeding effected without its prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned or to the extent fees or costs incurred pursuant to this Section 4.14 are attributable to the Indemnified Person’s breach of any of the representations, warranties, covenants or agreements made by the Purchasers in this Agreement or the other Transaction Documents. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.

4.15 Equal Treatment of Purchasers. No consideration shall be offered or paid to any Purchaser to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered to all of the Purchasers. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of shares of Common Stock or otherwise.

The Company shall pay all Transfer Agent fees, stamp taxes and other taxes and duties levied in connection with the issuance and sale of the Securities to the Purchasers.

6.2 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 thereof and supersede all prior agreements, understandings, discussions and representations, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. Before or at the Closing, the Company and the Purchasers will execute and deliver to the other such further documents as may be reasonably requested in order to give practical effect to the intention of the parties under the Transaction Documents.

6.3 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 on the earliest of (a) the date of transmission, if such notice or communication is delivered via electronic mail at the e-mail address specified in this Section 6.3 prior to 5:00 p.m., New York City time, on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via electronic mail at the e- mail address or facsimile number specified in this Section 6.3 on a day that is not a Trading Day or later than 5:00 p.m., New York City time, on any Trading Day, (c) the Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service with next day delivery specified, or (d) upon actual receipt by the party to whom such notice is required to be given if delivered personally or if sent by U.S. certified or registered mail, return receipt requested; provided, in the case of clauses (a) and (b), that notice shall not be deemed given or effective if the sender receives an automatic system-generated response that such electronic mail was undeliverable.

or such other address as may be designated in writing hereafter, in the same manner, by such Person.

6.4 Amendments; Waivers; No Additional Consideration. No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Purchasers who collectively have subscribed to purchase at least a majority in interest of the Securities, which majority must include each Purchaser that has a Subscription Amount (including the Subscription Amounts of such Purchaser’s affiliate and related funds) that is no less than $20,000,000, provided that (i) no amendment to Section 4.4, Section 4.6, Section 4.10, Section 4.11, Section 4.12, Section 4.14, Section 4.15, this Section 6.4 or Section 6.18 may be made without the consent of each Purchaser, or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought and (ii) any proposed amendment that would, by its terms, have a disproportionate and materially adverse effect on any Purchaser shall require the consent of such Purchaser(s). No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right. No consideration shall be offered or paid to any Purchaser to amend or consent to a waiver or modification of any provision of any Transaction Document unless the same consideration is also offered to all Purchasers (in the case of amendments or waivers following Closing, who then hold Securities). Notwithstanding anything to the contrary herein, without the express written consent of the Purchaser, this Agreement may not be amended, modified or waived to increase or decrease the number of Securities that such Purchaser is obligated to purchase hereunder or to increase or decrease the purchase price to be paid by such Purchaser for such Securities.

6.5 Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement or any of the Transaction Documents. As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

6.6 Successors and Assigns. The provisions of this Agreement shall inure to the benefit of and be binding upon the parties and their successors and permitted assigns. This Agreement, or any rights or obligations hereunder, may not be assigned by the Company without the prior written consent of each Purchaser. Any Purchaser may assign its rights hereunder in whole or in part to any Person to whom such Purchaser assigns or transfers any Securities in compliance with the Transaction Documents and applicable law, provided such transferee shall agree in writing to be bound, with respect to the transferred Securities, by the terms and conditions of this Agreement that apply to the Purchasers.

6.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except (i) the Placement Agents are intended third-party beneficiaries of the representations and warranties in Article 3, Section 4.4, Section 4.16 and Section 4.17, and of this Section 6.7 and Section 6.19 and (ii) the Purchaser Parties are intended beneficiaries of Section 4.14.

6.8 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

6.9 Survival. Subject to applicable statute of limitations, the representations, warranties, agreements and covenants contained herein shall survive the Closing and the delivery of the Securities.

6.10 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together 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, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, or by any electronic signature complying with the U.S. ESIGN Act of 2000 or the New York Electronic Signatures and Records Act, such signature shall create a legally valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

6.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

6.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

6.13 Replacement of Securities. If any certificate or instrument evidencing any Securities or Conversion Shares is mutilated, lost, stolen or destroyed, the Company may issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities or Conversion Shares. If a replacement certificate or instrument evidencing any Securities or Conversion Shares is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

6.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by Law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents, without the requirement of posting a bond. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation (other than in connection with any action for a temporary restraining order) the defense that a remedy at law would be adequate.

6.15 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any Law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.16 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event.

6.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. The decision of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser and any of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such information, materials, statement or opinions. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group (including, without limitation, a “group” within the meaning of Section 13(d)(3) of the Exchange Act) with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, Purchasers and their respective counsels may choose to communicate with the Company through Cooley LLP, counsel to the Placement Agents. Each Purchaser acknowledges that Cooley LLP has rendered legal advice to the Placement Agents and not to such Purchaser in connection with the transactions contemplated hereby, and that each such Purchaser has relied for such matters on the advice of its own respective counsel. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any Purchaser. It is expressly understood that each provision contained in this Agreement is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

6.18 Termination. This Agreement may be terminated and the sale and purchase of the Securities abandoned at any time prior to the Closing (i) automatically if the Closing has not been consummated on or prior to 5:00 p.m., New York City time, on the Outside Date or (ii) by a Purchaser (with respect to itself) if any of the conditions set forth in Section 5.1 shall have become incapable of fulfillment, and shall not have been waived by such Purchaser; provided, however, that the right to terminate this Agreement under clause (ii) shall not be available to any Person whose failure to comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such time. Nothing in this Section 6.18 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. In the event of a termination pursuant to this Section 6.18, the Company shall promptly notify all non-terminating Purchasers. Upon a termination in accordance with this Section 6.18, the Company and the terminating Purchaser(s) shall not have any further obligation or liability (including arising from such termination) to the other, and no Purchaser will have any liability to any other Purchaser under the Transaction Documents as a result therefrom.

6.19 Exculpation of the Placement Agents. Each party hereto agrees for the express benefit of the Placement Agents and their respective Affiliates and representatives that:

(a) The Placement Agents and their respective Affiliates and representatives (i) have no duties or obligations other than those specifically set forth herein or in their respective engagement letters; (ii) shall not be liable for any improper payment made in accordance with the information provided by the Company; (iii) make no representation or warranty, and have no 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 in connection with any of the transactions contemplated hereby, including any offering or marketing materials; and (iv) shall not be liable (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 them by this Agreement or any Transaction Document, or (B) for anything which any of them may do or refrain from doing in connection with this Agreement or any Transaction Document, except in each case for such Person’s own gross negligence, willful misconduct or bad faith.

(b) The Placement Agents and their respective Affiliates and representatives shall be entitled to (i) 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 (ii) be indemnified by the Company for acting as a Placement Agent hereunder pursuant to the indemnification provisions set forth in their respective engagement letters.

6.20 Waivers of Conflicts. Each party to this Agreement acknowledges that Covington & Burling LLP, counsel for the Company, may have in the past performed and may continue to perform legal services to one or more Purchasers or their affiliates in matters unrelated to the transactions described in this Agreement, including the representation of one or more Purchasers or their affiliates in matters of a similar nature to such transactions. Accordingly, except as otherwise agreed between the Company and a Purchaser, each party to this Agreement hereby (a) acknowledges that they have had an opportunity to ask for information relevant to this disclosure; and (b) gives its informed consent to Covington & Burling LLP’s representation of (i) one or more Purchasers or their affiliates in such unrelated matters and (ii) the Company in connection with this Agreement and the transactions contemplated hereby.

6.21 Arm’s Length Transaction. The Company acknowledges and agrees that (i) the transactions described in this Agreement are an arm’s-length commercial transaction between the parties, (ii) the Purchasers have not assumed nor will they assume an advisory or fiduciary responsibility in the Company’s favor with respect to any of the transactions contemplated by this Agreement or the process leading thereto, and the Purchasers have no obligation to the Company with respect to the transactions contemplated by this Agreement except those obligations expressly set forth in this Agreement or the other Transaction Documents to which they are a party, and (iii) the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives.

IN WITNESS WHEREOF, the parties hereto have caused this Securities Purchase Agreement to be duly executed by their respective authorized signatories as of the date first indicated above.
