Dear Mr. Weil:


 


In recognition of the relationship between
Hydra Industries Acquisition Corp. (the “Company”) and MIHI LLC, the Company agrees that prior to the third anniversary
of the date of this letter agreement, the Company shall, and shall cause its subsidiaries to, engage Macquarie Capital (USA) Inc.
(“Macquarie Capital”), or an affiliate of Macquarie Capital designated by it, to act, on any and all transactions with
a notional value greater than $30 million, as: (a) a bookrunning managing underwriter, a bookrunning managing placement agent,
or a bookrunning managing initial purchaser, as the case may be, in connection with any offering or placement of securities (including,
but not limited to, debt, equity, preferred and other hybrid equity securities or equity linked securities) by the Company or any
of its subsidiaries, in each case with Macquarie Capital receiving total compensation in respect of any such transaction that is
equal to or better than 40% of the total compensation received by all underwriters, placement agents, and initial purchasers, as
the case may be, in connection with such transaction and not less than the compensation received by any one individual underwriter,
placement agent or initial purchaser, as the case may be, and (b) a financial advisor in connection with any (i) restructuring
(through a recapitalization, extraordinary dividend, stock repurchase, spin-off, joint venture or otherwise) by the Company or
any of its subsidiaries, (ii) acquisition or disposition of a business, asset or voting securities by the Company or any of its
subsidiaries or (iii) debt or equity financing or any refinancing of any portion of any financing by the Company or any of its
subsidiaries, in each case with Macquarie Capital receiving total compensation in respect of any such transaction that is equal
to or greater than 40% of the total compensation received by all financial advisors in connection with such transaction (50% in
the case of the initial business combination (the “Business Combination”), and not less than the compensation received
by any individual financial advisor. The Company understands that Macquarie Capital may decline any such engagement in its sole
and absolute discretion, in which event Macquarie Capital would not be entitled to any fees from such engagement. Any engagement
of Macquarie Capital pursuant to this paragraph shall become a commitment by Macquarie Capital to assume such engagement only if
such engagement is set forth and agreed to by Macquarie Capital in writing in a separate agreement. Any such engagement shall be
on Macquarie Capital’s customary terms (including, as applicable, representations, warranties, covenants, conditions, indemnities
and fees based upon the prevailing market for similar services for global, full-service investment banks), which terms (but not
the obligation to engage Macquarie Capital) shall be subject to the review of the Company’s audit committee (the “Audit
Committee”) pursuant to the Audit Committee’s policies and procedures relating to transactions that may present conflicts
of interest.


 






    	 



    	 



    

 


With regard to the preceding scope of services,
it is understood that Macquarie Capital will not be retained to render a fairness opinion on the Business Combination, although
this letter agreement will apply with respect to other aspects of the Business Combination. If, in the sole and reasonable determination
of Macquarie Capital, Macquarie Capital is unable to provide the services requested under this agreement, Macquarie Capital will
notify the board of directors of the Company as soon as practical of its intention to decline such engagement, or to seek an appropriate
amendment to this agreement.


 


This letter agreement may be executed in
any number of counterparts, each of which shall be an original, and all of which, when taken together, shall constitute one agreement.
Delivery of an executed counterpart of this letter agreement by facsimile, email or other form of electronic transmission shall
be deemed to constitute due and sufficient delivery of such counterpart. This letter agreement and any related dispute shall be
governed by, and construed and interpreted in accordance with, the laws of the State of New York applicable to contracts executed
in and to be performed in that State.
