The Company will not disclose, summarize or refer to Consultant, the terms of this Agreement or any of Consultant’s advice publicly or to any third party without the prior written consent of Consultant, which consent may be given by the Principal Contact; provided, however that the Company may disclose Consultant’s advice on a confidential and non-reliance basis, to its legal, financial and accounting advisors (it being agreed that the Company will be responsible for any non-compliance for any of the foregoing confidentiality and non-reliance terms by any such advisors).

​

The Company agrees that no Consultant Party shall have any liability to the Company or its affiliates, or their respective owners, directors, officers, employees, security holders or creditors for any Losses (A)(i) related to or arising out of the Company’s actions or omissions (or the actions or omissions of the Company’s officers, directors, employees and agents other than Consultant) in connection with the matters contemplated in the Agreement, (ii) related to or arising out of oral or written statements or omissions made or information provided by the Company or its agents in connection with the matters contemplated in the Agreement, including, without limitation, all information in any Offering Memo or otherwise provided to counterparties by or on behalf of the Company (which shall be deemed to include the Company’s public filings) or (B) otherwise arising out of, related to or in connection with the Agreement, the matters contemplated in the Agreement or Consultant’s performance of the Agreement (or any other services or advice the Company requests Consultant to provide) in each case, including prior to the date of the Agreement, except that clause (B) shall not apply to Losses to the extent such Losses are finally judicially determined to have resulted primarily from the willful misconduct, bad faith or gross negligence of any Consultant Party.

If such indemnification or limitation on liability is for any reason not available or is insufficient to hold a Consultant Party harmless, the Company agrees to contribute to the Losses in such proportion as is appropriate to reflect the relative benefits received (or anticipated to be received) by the Company, on the one hand, and by Consultant, on the other hand, with respect to the Agreement or, if such allocation is judicially determined to be unavailable, in such proportion as is appropriate to reflect the relative benefits and relative fault of the Company, on the one hand, and of Consultant, on the other hand, and any other equitable considerations; provided, however, that, to the extent permitted by applicable law, in no event shall the Consultant Party be responsible for amounts that exceed the fees actually received by Consultant from the Company in connection with the Agreement. Relative benefits to the Company, on the one hand, and Consultant, on the other hand, with respect to the Agreement shall be deemed to be in the same proportion as (i) the total value paid or proposed to be paid or received or proposed to be received by the Company or its security holders, as the case may be, pursuant to the transaction(s) contemplated by the Agreement, whether or not consummated, bears to (ii) the fees actually received by Consultant in connection with the Agreement.

The Company will not permit any such Settlement to include a statement as to, or an admission of, fault or culpability by or on behalf of a Consultant Party without such Consultant Party’s prior written consent.

In the event that any Consultant Party becomes involved in any capacity in any Action arising out of, related to or in connection with the Agreement or any matter referred to in the Agreement (including, without limitation, related matters prior to the date of the Agreement), the Company will reimburse such Consultant Party for the reasonable out-of-pocket costs and expenses (including counsel fees) of investigating, preparing for and responding to such Action or enforcing the Agreement, as they are incurred.

Prior to effecting any proposed sale, exchange, dividend or other distribution or liquidation of all or substantially all of its assets or any significant recapitalization or reclassification of its outstanding securities that does not explicitly or by operation of law provide for the assumption of the obligations of the Company set forth herein, the Company will notify Consultant in writing of its arrangements for the Company’s obligations set forth herein to be assumed by another creditworthy party (for example through insurance, surety bonds or the creation of an escrow) upon terms and conditions reasonably satisfactory to the Company and Consultant.

Consultant will indemnify and hold harmless the Company, its affiliates and any of its respective current or former directors, officers, partners, managers, agents, representatives or employees (collectively, the “Company Parties”) from and against any losses, claims, damages, expenses or liabilities (collectively, “Company Losses”) related to, arising out of or in connection with the payment of amounts owed under this Agreement to the extent any person other than the Consultant seeks or alleges such person is due amounts for any fees, costs or expenses under this Agreement.
