374Water Inc

Attention: Chris Gannon, President and Chief Executive Officer

Dear Mr. Gannon:

This agreement (the “Agreement”) constitutes the agreement between D. Boral Capital LLC (the “Placement Agent” or “D. Boral”) and 374Water Inc., a corporation incorporated under the laws of Delaware (the “Company”), pursuant to which the Placement Agent shall serve as the exclusive placement agent for the Company, on a “reasonable best efforts” basis, in connection with the proposed placement (the “Placement”) of registered Common Stock (the “Shares”) of the Company, par value $0.0001  per share (the “Common Stock”), common stock purchase warrants to purchase Common Stock (the  “Warrants”). The Shares, the Warrants, and the Common Stock underlying the Warrants are collectively referred to herein as the “Securities”). The terms of the Placement and the Securities shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that the Placement Agent would have the power or authority to bind the Company or any Purchaser or an obligation for the Company to issue any Securities or complete the Placement.  This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with the Placement, including but not limited to the Purchase Agreement (as defined below), and the form of the Warrants shall be collectively referred to herein as the “Transaction Documents.”  The date of the closing of the Placement shall be referred to herein as the “Closing Date.” The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of the Placement Agent with respect to securing any other financing on behalf of the Company.  With the prior written consent of the Company, the Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement.  The sale of the Securities to any Purchaser will be evidenced by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser in a form reasonably acceptable to the Company and the Placement Agent.  Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement.  Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers.

SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY; COVENANTS OF THE COMPANY.

A. Representations of the Company. Each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Placement is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the Closing Date, hereby made to, and in favor of, the Placement Agent. In addition to the foregoing, the Company represents and warrants that:

1. The Company has prepared and filed with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3, as amended (Registration No. 333- 268942), and amendments thereto, and related preliminary prospectuses, for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Securities which registration statement, as so amended (including post-effective amendments, if any) became effective on December 30, 2022. At the time of such filing, the Company met the requirements of Form S-3 under the Securities Act. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies with said Rule. The Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a supplement to the form of prospectus included in such registration statement relating to the placement of the Securities and the plan of distribution thereof and has advised the Placement Agent of all further information (financial and other) with respect to the Company required to be set forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the “Registration Statement”; such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus”; and the supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus Supplement.” Any reference in this Agreement to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”) which were filed under the Exchange Act on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the Company’s knowledge, is threatened by the Commission. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and the “Time of Sale Prospectus” means the preliminary prospectus, if any, together with the free writing prospectuses, if any, used in connection with the Placement, including any documents incorporated by reference therein.

2. The Registration Statement (and any further documents to be filed with the Commission) contains all material exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations. Each of the Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein (with respect to Incorporated Documents incorporated by reference in the Base Prospectus or Prospectus Supplement), in the light of the circumstances under which they were made not misleading; and any further documents so filed and incorporated by reference in the Base Prospectus, the Time of Sale Prospectus or Prospectus Supplement, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other documents required to be described in the Base Prospectus, the Time of Sale Prospectus or Prospectus Supplement, or to be filed as exhibits or schedules to the Registration Statement, which (x) have not been described or filed as required or (y) will not be filed within the requisite time period.

3. The Company is eligible to use free writing prospectuses in connection with the Placement pursuant to Rules 164 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or behalf of or used by the Company complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. The Company will not, without the prior consent of the Placement Agent, which consent shall not be unreasonably withheld, prepare, use or refer to, any free writing prospectus.

4. There are no affiliations with any FINRA member firm among the Company’s officers, directors or, to the knowledge of the Company, any ten percent (10.0%) or greater shareholder of the Company, except as set forth in the Registration Statement and the other documents the Company has filed or furnished with the Commission.

B. Covenants of the Company. The Company has delivered, or will as promptly as practicable deliver, to the Placement Agent materially complete conformed copies of the Registration Statement and of each consent and certificate of experts, as applicable, filed as a part thereof, and conformed copies of the Registration Statement (without exhibits), the Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement, as amended or supplemented, in such quantities and at such places as the Placement Agent reasonably requests. Neither the Company nor any of its directors and officers has distributed and none of them will distribute, prior to the Closing Date, any offering material in connection with the offering and sale of the Securities pursuant to the Placement other than the Base Prospectus, the Time of Sale Prospectus, the Prospectus Supplement, the Registration Statement, copies of the documents incorporated by reference therein and any other materials permitted by the Securities Act.

SECTION 2. REPRESENTATIONS OF THE PLACEMENT AGENT. The Placement Agent represents and warrants that it (i) is a member in good standing of FINRA, (ii) is registered as a broker/dealer under the Exchange Act, (iii) is licensed as a broker/dealer under the laws of the states applicable to the offers and sales of the Securities by such Placement Agent, (iv) is and will be a body corporate validly existing under the laws of its place of incorporation, and (v) has full power and authority to enter into and perform its obligations under this Agreement. The Placement Agent will immediately notify the Company in writing of any change in its status as such. The Placement Agent covenants that it will use its reasonable best efforts to conduct the Placement hereunder in compliance with the provisions of this Agreement and the requirements of applicable law.

SECTION 3. COMPENSATION. In consideration of the services to be provided for hereunder, the Company shall pay to the Placement Agent or their respective designees their pro rata portion (based on the Securities placed) of the following compensation with respect to the Securities which they are placing:

A. A cash fee equal to (i) an aggregate of five percent (5%) of the aggregate gross proceeds raised in the Placement from the sale of securities by the Company to Purchasers introduced to the Company by the Placement Agent; and (ii) an aggregate of two and a half percent (2.5%) of the aggregate gross proceeds raised in the Placement from the sale of securities by the Company to Purchasers introduced by the Company; provided however, that the gross proceeds raised in the Placement from the sale of securities by the Company to the Purchasers introduced by D. Boral are equal to or greater than $5,000,000 (the “Cash Fee”). The Cash Fee shall be limited to the proceeds from the Placement and paid at the closing of the Placement (the “Closing”).

B. Subject to compliance with FINRA Rule 5110(f)(2)(D), the Company also agrees, (i) in the event that the Company consummates the Placement, to pay, or reimburse if paid by the Placement Agent, all reasonable and documented out-of-pocket costs and expenses incident to the performance of the obligations of the Placement Agent under this Agreement (including, without limitation, the fees and expenses of the Placement Agent’s outside attorneys), provided that, except as otherwise provided in Addendum A, such costs and expenses shall not exceed $75,000 without the Company’s prior written approval (such approval not to be unreasonably withheld, conditioned or delayed) and (ii) in the event that the Company executes a term sheet with a Purchaser but at the Company’s election the Placement is not consummated, the Company shall still reimburse the Placement Agent for its incurred accountable reasonable and documented out-of-pocket expenses subject to a cap of $25,000. The Company will pay or reimburse Placement Agent directly upon the Closing of the Placement from the gross proceeds raised in the Placement for all amounts owed under clause (i) of the preceding sentence. For the avoidance of doubt, in the event that the Company does not consummate the Placement at the election of the Placement Agent or the Purchasers, the Company shall have no obligation to reimburse the Placement Agent for any costs and expenses.

C. The Placement Agent reserves the right to reduce any item of its compensation or adjust the terms thereof as specified herein in the event that a determination shall be made by FINRA to the effect that such Placement Agent’s aggregate compensation is in excess of FINRA rules or that the terms thereof require adjustment.

SECTION 4. INDEMNIFICATION. The Company agrees to the indemnification and other agreements set forth in the Indemnification Provisions (the “Indemnification”) attached hereto as Addendum A, the provisions of which are incorporated herein by reference and shall survive the termination or expiration of this Agreement.

SECTION 5. ENGAGEMENT TERM. The Placement Agent’s engagement hereunder shall be until the earlier of (i) the final closing date of the Placement and (ii) the date when either party to this Agreement terminates the engagement according to the terms as set forth in the next sentence (such date, the “Termination Date”). The Agreement may be terminated at any time by either party upon 10 days written notice to the other party. Notwithstanding anything to the contrary contained herein, the provisions concerning confidentiality, indemnification, contribution and the Company’s obligations to pay fees and reimburse expenses contained herein and the Company’s obligations contained in the Indemnification Provisions will survive any expiration or termination of this Agreement for twelve (12) months, irrespective of whether a closing occurs. All such fees and reimbursements due shall be paid to the Placement Agent on or before the Termination Date (in the event such fees and reimbursements are earned or owed as of the Termination Date) or upon the closing of the Placement or any applicable portion thereof (in the event such fees and reimbursements are due as of the Termination Date). The Placement Agent agrees not to use any confidential information concerning the Company provided to them by the Company for any purposes other than those contemplated under this Agreement.

SECTION 6. PLACEMENT AGENT INFORMATION. The Company agrees that any information or advice rendered by the Placement Agent in connection with this engagement is for the confidential use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company will not disclose or otherwise refer to the advice or information in any manner without the Placement Agent’s prior written consent.

SECTION 7.LOCK-UP AGREEMENT.

SECTION 8. NO FIDUCIARY RELATIONSHIP. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or entity not a party hereto, except those entitled hereto by virtue of the Indemnification Provisions hereof. The Company acknowledges and agrees that the Placement Agent is not and shall not be construed as a fiduciary of the Company and shall have no duties or liabilities to the equity holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of such Placement Agent hereunder, all of which are hereby expressly waived.

SECTION 9. CLOSING. The obligations of the Placement Agent, and the closing of the sale of the Securities hereunder are subject to the accuracy, when made and on the Closing Date, of the representations and warranties on the part of the Company and its subsidiaries contained herein and in the Purchase Agreement, to the accuracy of the statements of the Company and its subsidiaries made in any certificates pursuant to the provisions hereof, to the performance by the Company and its subsidiaries of their obligations hereunder, and to each of the following additional terms and conditions, except as otherwise disclosed to and acknowledged and waived by the Placement Agent to the Company:

C. All corporate proceedings and other legal matters incident to the authorization, form, execution, delivery and validity of each of this Agreement, the Shares, the Registration Statement, the Base Prospectus and the Prospectus Supplement and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all material respects to counsel for the Placement Agent, and the Company shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

D. The Placement Agent shall have received from outside counsel to the Company such counsel’s written opinions, including a negative assurance letter, addressed to the Placement Agent and the Purchasers and dated as of the Closing Date, in form and substance reasonably satisfactory to the Placement Agent.

SECTION 10. [***]

SECTION 11. GOVERNING LAW; AGENT FOR SERVICE OF PROCESS, ETC. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made and to be performed entirely in such State, without regard to the conflicts of laws principles thereof. This Agreement may not be assigned by either party without the prior written consent of the other party. This Agreement shall be binding upon and inure to the benefit of the parties hereto, and their respective successors and permitted assigns. Any right to trial by jury with respect to any dispute arising under this Agreement or any transaction or conduct in connection herewith is waived. Any dispute arising under this Agreement may be brought into the courts of the State of New York or into the federal court located in New York, New York and, by execution and delivery of this Agreement, the Company hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of aforesaid courts. Each party hereto hereby irrevocably waives personal service of process and consents, to the extent permitted by applicable law, to process being served in any such suit, action or proceeding by delivering a copy thereof via 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. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment. If either party shall commence an action or proceeding to enforce any provisions of a Transaction Document, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorney’s fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. In addition to and without limiting the foregoing, the Company has confirms that it has appointed Christian Gannon, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon the this Agreement or the Transaction Documents or the transactions contemplated herein which may be instituted in any New York federal or state court, by the Placement Agent, the directors, officers, partners, members, managers, employees and agents of the Placement Agent, and expressly accept the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. The Company hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. The Company hereby authorizes and directs the Authorized Agent to accept such service. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company. If the Authorized Agent shall cease to act as agent for service of process, the Company shall appoint, without unreasonable delay, another such agent in the United States, and notify you of such appointment. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by the Placement Agent, the directors, officers, partners, members, managers, employees and agents of the Placement Agent, in any court of competent jurisdiction in the State of New York. This paragraph shall survive any termination of this Agreement, in whole or in part.

SECTION 12. ENTIRE AGREEMENT/MISCELLANEOUS. This Agreement (including the attached Indemnification Provisions) embodies the entire agreement and understanding between the parties hereto, and supersedes all prior agreements and understandings, relating to the subject matter hereof. If any provision of this Agreement is determined to be invalid or unenforceable in any respect, such determination will not affect such provision in any other respect or any other provision of this Agreement, which will remain in full force and effect. This Agreement may not be amended or otherwise modified or waived except by an instrument in writing signed by both Placement Agent and the Company. The representations, warranties, agreements and covenants contained herein shall survive the closing of the Placement and delivery of the Securities. 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 a .pdf format file, such signature shall create a 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.

SECTION 13. CONFIDENTIALITY. The Placement Agent (i) will keep the Confidential Information (as such term is defined below) confidential and will not (except as required by applicable law or stock exchange requirement, regulation or legal process (“Legal Requirement”), without the Company’s prior written consent, disclose to any person any Confidential Information, and (ii) will not use any Confidential Information other than in connection with the Placement. The Placement Agent further agrees, severally and not jointly, to disclose the Confidential Information only to its Representatives (as such term is defined below) who need to know the Confidential Information for the purpose of the Placement, and who are informed by the Placement Agent of the confidential nature of the Confidential Information. The term “Confidential Information” shall mean, all confidential, proprietary and non-public information (whether written, oral or electronic communications) furnished by the Company to a Placement Agent or its Representatives in connection with such Placement Agent’s evaluation of the Placement. The term “Confidential Information” will not, however, include information which (i) is or becomes publicly available other than as a result of a disclosure by a Placement Agent or its Representatives in violation of this Agreement, (ii) is or becomes available to a Placement Agent or any of its Representatives on a non-confidential basis from a third-party who, to the Placement Agent’s and its Representatives’ knowledge, as applicable, is not bound by obligations of confidentiality to the Company with respect to such information, (iii) is known to a Placement Agent or any of its Representatives prior to disclosure by the Company or any of its Representatives from a source not bound by obligations of confidentiality to the Company with respect to such information, or (iv) is or has been independently developed by a Placement Agent and/or the Representatives without use of any Confidential Information furnished to it by the Company. The term “Representatives” shall mean the Placement Agent’s directors, board committees, officers, employees, financial advisors, attorneys and accountants. This provision shall be in full force until the earlier of (a) the date that the Confidential Information ceases to be confidential and (b) two years from the date hereof. Notwithstanding any of the foregoing, in the event that the Placement Agent or any of their respective Representatives are required by Legal Requirement to disclose any of the Confidential Information, such Placement Agent and their respective Representatives will notify the Company in writing, as promptly as practicable, prior to disclosure of such information, and furnish only that portion of the Confidential Information which such Placement Agent or their respective Representative, as applicable, is required to disclose by Legal Requirement as advised by counsel, and will use reasonable efforts to obtain reliable assurance that confidential treatment will be accorded the Confidential Information so disclosed.

SECTION 14. 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 sent to the email address specified on the signature pages attached hereto prior to 6:30 p.m. (New York City time) on a business day, (b) the next business day after the date of transmission, if such notice or communication is sent to the email address on the signature pages attached hereto on a day that is not a business day or later than 6:30 p.m. (New York City time) on any business day, (c) the third business day following the date of mailing, if sent by U.S. internationally recognized air courier service, or (d) upon actual receipt 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 hereto.

SECTION 15. PRESS ANNOUNCEMENTS. The Company agrees that the Placement Agent shall, from and after any public announcement of the Closing, have the right to reference the Placement and the Placement Agent’s role in connection therewith in the Placement Agent’s marketing materials and on its website and to place advertisements in financial and other newspapers and journals, in each case at its own expense.

(the “Company”) pursuant to a placement agency agreement dated as of the date hereof, between the Company and the Placement Agent, as it may be amended from time to time in writing (the “Agreement”), the Company hereby agrees as follows:

1. To the extent permitted by law, the Company will indemnify the Placement Agent and its affiliates, directors, officers, employees and controlling persons (within the meaning of Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including the reasonable fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to the Agreement, except, with regard to the Placement Agent, to the extent that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final judgment (not subject to appeal) by a court of law to have resulted primarily and directly from any indemnitee’s bad faith, willful misconduct, fraud or gross negligence.

2. Promptly after receipt by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent is entitled to indemnity hereunder, the Placement Agent will notify the Company in writing of such claim or of the commencement of such action or proceeding, and the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to the Placement Agent and will pay the reasonable fees and expenses of such counsel. Notwithstanding the preceding sentence, the Placement Agent will be entitled to employ counsel separate from counsel for the Company and from any other party in such action if counsel for the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable fees and disbursements of no more than one such separate counsel will be paid by the Company. The Company will have the exclusive right to settle the claim or proceeding provided that the Company will not settle any such claim, action or proceeding without the prior written consent of the Placement Agent, which will not be unreasonably withheld. The Placement Agent and all other indemnitees shall not settle any claim, action or proceeding without the prior written consent of the Company.

3. The Company agrees to notify the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding relating to a transaction contemplated by the Agreement.

4. If for any reason the foregoing indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute to the amount paid or payable by the Placement Agent, as the case may be, as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand, and the Placement Agent on the other, but also the relative fault of the Company on the one hand and the Placement Agent on the other that resulted in such losses, claims, damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, the Placement Agent’s share of the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under the Agreement (excluding any amounts received as reimbursement of expenses incurred by the Placement Agent).

5. These Indemnification Provisions shall remain in full force and effect whether or not the transaction contemplated by the Agreement is completed and shall survive the termination of the Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party under the Agreement or otherwise.
