Ladies

Capitalized
terms not otherwise defined in this letter agreement (the “Letter Agreement”) shall have the meanings set forth in
the Securities Purchase Agreement. Pursuant to Section 5(c) of the Securities Purchase Agreement and in satisfaction of the Buyer(s)
obligation(s) under the Securities Purchase Agreement, the Buyer(s) irrevocably agree(s) with the Company that, from the date hereof
until the 18 month anniversary of the Effective Date, or such other earlier date as specified in the Securities Purchase Agreement, (such
period, the “Restriction Period”), the Buyer will not offer, sell, contract to sell, hypothecate, pledge or otherwise
dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether
by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Buyer or any affiliate of the Buyer
or any person in privity with the Buyer or any affiliate of the Buyer), directly or indirectly, or establish or increase a put equivalent
position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any
Conversion Shares beneficially owned, held or hereafter acquired by the Buyer(s) (the “Securities”). For the avoidance
of doubt, this Letter Agreement applies only to the Conversion Shares pursuant to the Securities Purchase Agreement and not any other
holdings in the Company Buyer or its affiliates may have now or in the future. Beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act. In order to enforce this covenant, the Company shall impose irrevocable stop-transfer instructions
preventing Continental Stock Transfer & Trust Company, the transfer agent, from effecting any actions in violation of this Letter
Agreement.


 


The
Buyer(s) acknowledge(s) that the execution, delivery and performance of this Letter Agreement is a material inducement to the Company
to complete the transactions contemplated by the Securities Purchase Agreement and that each Buyer (which shall be a third-party beneficiary
of this Letter Agreement) and the Company shall be entitled to specific performance of each undersigned’s obligations hereunder.
Each undersigned hereby represents that each undersigned has the power and authority to execute, deliver and perform this Letter Agreement,
that each undersigned has received adequate consideration therefor and that each undersigned will benefit from the closing of the transactions
contemplated by the Securities Purchase Agreement.


 


This
Letter Agreement may not be amended or otherwise modified in any respect without the written consent of the Company and each Buyer. This
Letter Agreement shall be construed and enforced in accordance with the laws of the State of New York without regard to the principles
of conflict of laws. The undersigned hereby irrevocably submits to the exclusive jurisdiction of the United States District Court sitting
in the Southern District of New York and the courts of the State of New York located in Manhattan, for the purposes of any suit, action
or proceeding arising out of or relating to this Letter Agreement, and hereby waives, and agrees not to assert in any such suit, action
or proceeding, any claim that (i) it is not personally subject to the jurisdiction of such court, (ii) the suit, action or proceeding
is brought in an inconvenient forum, or (iii) the venue of the suit, action or proceeding is improper. The Buyer(s) hereby irrevocably
waive(s) personal service of process and consents to process being served in any such suit, action or proceeding by receiving a copy
thereof sent to the Company at the address in effect for notices to it under the Securities Purchase Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof. The Buyer(s) hereby waive(s) any right to a trial by jury.
Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. The Buyer(s)
agree(s) each Buyer is not entitled to cast any votes on the matters herein contemplated and that no issuance or sale of the Securities
is created or intended by virtue of this Letter Agreement.


 


By
its signature below, the transfer agent hereby acknowledges and agrees that, reflecting this Letter Agreement, it has placed an irrevocable
stop transfer instruction on all Securities beneficially owned by the Buyer(s) until the end of the Restriction Period. This Letter Agreement
shall be binding on successors and assigns of the Buyer(s) with respect to the Securities and any such successor or assign shall enter
into a similar agreement for the benefit of the Buyer(s).


 


This
Letter Agreement may be executed in two or more counterparts, all of which when taken together may be considered one and the same agreement.
