(a) Except as set forth below, no public release or announcement concerning the transactions contemplated hereby shall be issued by the Investors without the prior consent of the Company, except as such release or announcement may be required by law or the applicable rules or regulations of any securities exchange or securities market, in which case the Investors shall allow the Company reasonable time to comment on such release or announcement in advance of such issuance. Notwithstanding the foregoing, each Investor may identify the Company and the value of such Investor’s security holdings in the Company in accordance with applicable investment reporting and disclosure regulations or internal policies without prior notice to or consent from the Company (including, for the avoidance of doubt, filings pursuant to Sections 13 and 16 of the 1934 Act). The Company shall not include the name of any Investor or any Affiliate or investment adviser of such Investor in any press release or public announcement (which, for the avoidance of doubt, shall not include any SEC Filing to the extent such disclosure is required by SEC rules and regulations) without the prior written consent of such Investor.

(b) No later than the Trading Day immediately following the date hereof, the Company shall issue one or more press releases disclosing all material terms of the transactions contemplated by this Agreement (the “Press Releases”). From and after the issuance of the Press Release, any Investor who did not receive the Additional Disclosure shall not be in possession of any material, non-public information received from the Company or any of its officers, directors, affiliates, employees or agents (including the Placement Agents).

(c) No later than 10 days after the date of this Agreement, the Company shall issue a press release and/or a Current Report on Form 8-K disclosing the Additional Disclosure (the “Cleansing Disclosure”), as such material non-public information may be updated from time-to-time including through the inclusion of additional data. From and after the issuance of the Cleansing Disclosure, no Investor who received the Additional Disclosure shall be in possession of any material non-public information received from the Company, its subsidiaries or any of their respective officers, directors, employees or agents (including the Placement Agents).

(d) The Company understands and confirms that the Investors will rely on the foregoing representations in effecting transactions in securities of the Company. The Company will make such other filings and notices in the manner and time required by the SEC or Nasdaq.

9.8. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any provision of law which renders any provision hereof prohibited or unenforceable in any respect.

9.9. Benefit of Agreement. The Placement Agents are an intended third-party beneficiary of the representations and warranties of the Company and of each Investor set forth in Section 4 and Section 5, respectively, of this Agreement.

9.10. Entire Agreement. This Agreement, including the signature pages, Exhibits, the other Transaction Documents and any confidentiality agreements between the Company and each Investor constitute the entire agreement among the parties hereof with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof.

9.11. Other Agreements. The Company has not entered into any side letter or similar agreement with any Investor pursuant to which such Investor has been or will be granted any terms relating to the Placement Securities or the registration therefore that are more favorable to such Investor than the terms granted to each other Investor.

9.12. Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

9.13. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to the choice of law principles thereof (other than sections 5-1401 and 5-1402 of the General Obligations of Law). Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suits, action, proceeding or judgement relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any suit, action or proceeding. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

9.14. Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase Placement Securities pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group (including a “group” within the meaning of Section 13(d)(3) of the 0000 Xxx) with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Investor 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 Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and an Investor, solely, and not between the Company and the Investors collectively and not between and among the Investors.

9.15. Exculpation of the Placement Agents. Each party hereto agrees for the express benefit of the Placements Agent and its Affiliates and representatives that:

(a) none of the Placement Agents, their respective Affiliates or any of their representatives (1) has any duties or obligations other than those specifically set forth herein or (x) with respect to Xxxxxxxxx LLC, in the engagement letter, dated as of November 22, 2022, between the Company and Xxxxxxxxx LLC and (y) with respect to Xxxxx Xxxxxxx & Co., in the engagement letter, dated as of November 29, 2022, between the Company and Xxxxx Xxxxxxx & Co., (C) with respect to Barclays Capital, Inc., dated as of December 4, 2022 between the Company and Barclays Capital, Inc., (D) with respect to Xxxxxx X.

(b) The Placement Agents, their Affiliates and their representatives shall be entitled to (1) rely on, and shall be protected in acting upon, any certificate, instrument, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as the Placement Agents hereunder pursuant to the indemnification provisions set forth in the applicable engagement letter.
