Attn: Frank Celli, Chief Executive Officer


 


Dear Mr. Celli:


 


This letter (the “Agreement”)
constitutes the agreement between Spartan Capital Securities, LLC (“Spartan” or the “Placement Agent”)
and BioHiTech Global, Inc. (the “Company”), that Spartan 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 shares (the “Shares” or the “Securities”) of the Company’s common stock,
par value $0.0001 per share (the “Common Stock”). 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 Spartan 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 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 Spartan’s obligations hereunder are on a “reasonable best efforts”
basis only and that the execution of this Agreement does not constitute a commitment by Spartan to purchase the Securities and
does not ensure the successful placement of the Securities or any portion thereof or the success of Spartan with respect to securing
any other financing on behalf 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. Notwithstanding anything herein to the contrary, the parties acknowledge that the
Company may offer Shares to certain Purchasers without employing the services of the Placement Agent.


 


SECTION 1. COMPENSATION.


 


The Company will pay
Spartan: (i) a cash fee equal to 7% of the gross proceeds received by the Company from the sale of the Securities to investors
introduced to the Company by Spartan at the closing of the Placement (the “Closing”), which shall be deemed
to include all investors for which Spartan provides executed Transaction Documents to the Company; (ii) a cash fee equal to 3.5%
of the gross proceeds received by the Company from the sale of the Securities to investors introduced to the Company by the Company;
and (iii) a number of warrants equal to 3.0% of the gross proceeds paid for any equity or equity-linked securities issued by the
Company (the “Placement Agent Warrant Agreement”). The Placement Agent Warrant Agreement, in the form attached
hereto as Exhibit [ ], shall be exercisable, in whole or in part, commencing on a date which is six months and one day after the
Closing and expiring on the five-year anniversary of the Closing at an exercise price per share equal to 125% of the purchase price
of the Shares. The Placement Agent Warrant Agreement and the shares of Common Stock issuable upon exercise thereof are hereinafter
referred to as the “Placement Agent’s Securities.” The Company also agrees to reimburse Spartan’s out-of-pocket
expenses, up to a maximum of $100,000, in the event of a Closing, payable immediately upon the Closing or in the event a Closing
does not occur, $50,000 payable on the sixtieth calendar day after execution of this Agreement.


 




     


     


    

 


SECTION 2. REGISTRATION STATEMENT.


 


The Company represents and warrants to,
and agrees with, the Placement Agent that:


 


(A) The Company has
filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (Registration
File No. 333-225999) under the Securities Act of 1933, as amended (the “Securities Act”), which became effective
on July 11, 2018, for the registration under the Securities Act of the Securities. At the time of such filing and as of the filing
of the Company’s Form 10-K for the year ended December 31, 2018, 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”) pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (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 Base Prospectus, or 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.


 


(B) The Registration
Statement (and any further documents to be filed with the Commission) contains all 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, if any, 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, if
any, 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 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 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, if any, 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 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, if any, or Prospectus
Supplement, or to be filed as exhibits or schedules to the Registration Statement, which have not been described or filed as required.


 




     


     


    

  


(C) 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, prepare, use or refer to, any free writing prospectus.


 


(D) The Company has
delivered, or will as promptly as practicable deliver, to the Placement Agent 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, if any, and the Prospectus Supplement, as amended
or supplemented, in such quantities and at such places as the Placement Agent reasonably requests. Placement Agent acknowledges
that all such materials as exist on the date of this letter are available on EDGAR. 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 Shares pursuant to the Placement other than the Base Prospectus, the Time of Sale Prospectus, if any,

(E) The Company has
the requisite corporate power and authority to enter into and to consummate the transactions contemplated by this Agreement, the

hereunder and thereunder. The execution and delivery of each of this Agreement and the Transaction Documents by the Company and
the consummation by it of the transactions contemplated hereby and thereby and under the Prospectus Supplement have been duly authorized
by all necessary action on the part of the Company and no further action is required by the Company, the Company’s Board
of Directors (the “Board of Directors”) or the Company’s stockholders in connection therewith. This Agreement
has been duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding
obligation of the Company enforceable against the Company in accordance with its terms, except (i) as limited by general equitable
principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement
of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive
relief or other equitable remedies, and (iii) insofar as indemnification and contribution provisions may be limited by applicable
law.


 


(F) The execution,
delivery and performance by the Company of this Agreement and the transactions contemplated pursuant to the Transaction Documents
and the Prospectus Supplement, the issuance and sale of the Securities and the consummation by it of the transactions contemplated

or (b) if disclosed orally or otherwise than in writing, is identified as confidential and/or proprietary at the time of disclosure

ADDENDUM A


 


INDEMNIFICATION PROVISIONS


 


In connection with
the engagement of Spartan Capital Securities, LLC (“Spartan”) by BioHiTech Global, Inc. (the “Company”)
pursuant to a letter agreement dated September 5, 2019, between the Company and Spartan, as it may be amended from time to time
in writing (the “Agreement”), the Company hereby agrees as follows:




 


	1.	The Company hereby agrees to indemnify and hold Spartan, its officers, directors, principals, employees, affiliates, and stockholders, and their successors and assigns, harmless from and against any and all loss, claim, damage, liability, deficiencies, actions, suits, proceedings, costs and legal expenses or expense whatsoever (including, but not limited to, reasonable legal fees and other expenses and reasonable disbursements incurred in connection with investigating, preparing to defend or defending any action, suit or proceeding, including any inquiry or investigation, commenced or threatened, or any claim whatsoever, or in appearing or preparing for appearance as witness in any proceeding, including any pretrial proceeding such as a deposition) (collectively the “Losses”) arising out of, based upon, or in any way related or attributed to, (i) any breach of a representation, warranty or covenant by the Company contained in this Agreement; (ii) the Registration Statement, the Base Prospectus, or the Prospectus Supplement (as from time to time each may be amended and supplemented); (iii) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the Placement, including any “road show” or investor presentations made to investors by the Company (whether in person or electronically); or (iv) any activities or services performed hereunder by Spartan, unless it is finally judicially determined in a court of competent jurisdiction that such Losses were the primary and direct result of the intentional misconduct or gross negligence of Spartan in performing the services hereunder or information provided by Spartan expressly for inclusion in the Prospectus Supplement.
	 	 
	2.	If Spartan receives written notice of the commencement of any legal action, suit or proceeding with respect to which the Company is or may be obligated to provide indemnification pursuant to this Section (B), Spartan shall, within twenty (20) days of the receipt of such written notice, give the Company written notice thereof (a “Claim Notice”). Failure to give such Claim Notice within such twenty (20) day period shall not constitute a waiver by Spartan of its right to indemnity hereunder with respect to such action, suit or proceeding; provided, however, the indemnification hereunder may be limited by any such failure to provide a Claim Notice to the Company that materially prejudices the Company. Upon receipt by the Company of a Claim Notice from Spartan with respect to any claim for indemnification which is based upon a claim made by a third party (“Third Party Claim”), the Company may assume the defense of the Third Party Claim with counsel reasonably satisfactory to Spartan, as described below. Spartan shall cooperate in the defense of the Third Party Claim and shall furnish such records, information and testimony and attend all such conferences, discovery proceedings, hearings, trial and appeals as may be reasonably required in connection therewith. Spartan shall have the right to employ its own counsel in any such action which shall be at the Company’s expense if (i) the Company and Spartan shall have mutually agreed in writing to the retention of such counsel, (ii) the Company shall have failed in a timely manner to assume the defense and employ counsel or experts reasonably satisfactory to Spartan in such litigation or proceeding or (iii) the named parties to any such litigation or proceeding (including any impleaded parties) include the Company and Spartan and representation of the Company and Spartan by the same counsel or experts would, in the reasonable opinion of Spartan, be inappropriate due to actual or potential differing interests between the Company and Spartan. The Company shall not satisfy or settle any Third Party Claim for which indemnification has been sought and is available hereunder, without the prior written consent of Spartan, which consent shall not be delayed and which shall not be required if Spartan is granted an unconditional release in connection therewith in such form as reasonably acceptable to Spartan, and if such release does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of Spartan, or its officers, directors, principals, employees, affiliates, and stockholders. The indemnification provisions hereunder shall survive the termination or expiration of this Agreement.


 




     


     


    

 


	3.	The Company further agrees, upon demand by Spartan, to promptly advance and/or reimburse Spartan for, or pay, any loss, claim, damage, liability or expense as to which Spartan has been indemnified herein with such reimbursement to be made currently as any loss, damage, liability or expense is incurred by Spartan. Notwithstanding the provisions of the aforementioned Indemnification, any such advancement, reimbursement or payment by the Company of fees, expenses, or disbursements incurred by Spartan shall be repaid by Spartan in the event of any proceeding in which a final judgment (after all appeals or the expiration of time to appeal) is entered in a court of competent jurisdiction against Spartan based solely upon its gross negligence or intentional misconduct in the performance of its duties hereunder or the information provided by Spartan expressly for inclusion in the Prospectus Supplement, and provided further, that the Company shall not be required to make reimbursement or payment for any settlement effected without the Company’s prior written consent (which consent shall not be unreasonably withheld or delayed).
	 	 
	4.	If for any reason the foregoing indemnification is unavailable or is insufficient to hold such indemnified party harmless, the Company agrees to contribute the amount paid or payable by such indemnified party in such proportion as to reflect not only the relative benefits received by the Company, as the case may be, on the one hand, and Spartan, on the other hand, but also the relative fault of the Company and Spartan as well as any relevant equitable considerations. In no event shall Spartan contribute in excess of the fees actually received by it pursuant to the terms of this Agreement.
	 	 
	5.	For purposes of this Agreement, each officer, director, stockholder, and employee or affiliate of Spartan and each person, if any, who controls Spartan (or any affiliate) within the meaning of either Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934, as amended, shall have the same rights as Spartan with respect to matters of indemnification by the Company hereunder.
