1. Escrow
Agreement Amendment. Effective as of the date hereof, Section 3.2 of the Escrow Agreement shall be deleted in its entirety and
replaced with the following:


“3.2
Except as otherwise set forth herein, the Escrow Agent shall hold the shares remaining after any cancellation required pursuant to Section
3.1 above (such remaining shares to be referred to herein as the “Escrow Shares”). Of such remaining shares,
5,062,500 shares of Common Stock held by Sponsor shall be referred to herein as the “Sponsor Upfront Escrow
Shares” and held pursuant to Section 3.2(a), all of the shares of Common Stock held by Founders other than Sponsor
shall be referred to as “Founder Upfront Escrow Shares” and held pursuant to Section 3.2(a) and 1,687,500
shares of Common Stock held by Sponsor shall be referred to herein as the “Sponsor Earn-Out Escrow Shares” and
held pursuant to Section 3.2(b).




    


     


    

 


(a) Release
of Sponsor Upfront Escrow Shares and Founder Upfront Escrow Shares.  The Sponsor Upfront Escrow Shares and the Founder Upfront
Escrow Shares shall be held until (i) with respect to 3,375,000 Sponsor Upfront Escrow Shares and 45,000 Founder Upfront Escrow
Shares, the earlier of (A) one year following the date of the consummation of the transactions contemplated by the Merger Agreement,
dated as of February 1, 2021 (as amended, the “Merger Agreement”), by and among the Company, TSCN Merger Sub Inc.
and Microvast, Inc. (the “Anniversary Release Date”) and (B) the date on which the last sale price of the Common
Stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations) for
any 20 trading days within any 30-trading day period following the consummation of the transactions contemplated by the Merger
Agreement, and (ii) with respect to the remaining Sponsor Upfront Escrow Shares and Founder Upfront Escrow Shares, the Anniversary
Release Date (such period of time during which the Founder Upfront Escrow Shares are held in escrow, the “Founder Upfront
Escrow Period”). Upon expiration of the Founder Upfront Escrow Period, the Escrow Agent shall disburse and release to the
Founders all Sponsor Upfront Escrow Shares and all Founder Upfront Escrow Shares, as applicable (and any applicable stock power),
upon receipt of a written notice executed by Tuscan Holdings Acquisition LLC (“Sponsor”), in form reasonably
acceptable to the Escrow Agent, certifying the expiration of the Founder Upfront Escrow Period and the number of Sponsor Upfront
Escrow Shares and Founder Upfront Escrow Shares to be disbursed and released to each Founder. The Escrow Agent shall have no further
duties under this Section 3.2(a) with respect to the Founder Upfront Escrow Shares after the disbursement of the Sponsor
Escrow Shares and Founder Upfront Escrow Shares to the Founders in accordance with this Section 3.2(a).


(b) Release
of Sponsor Earn-Out Escrow Shares. The Escrow Agent shall hold, disburse and release the Sponsor Earn-Out Escrow Shares as
follows:


(i)
The Escrow Agent shall hold the 50% of the Sponsor Earn-Out Escrow Shares until the later of (A) the Anniversary Release Date and
(B) the date on which the last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits,
stock dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period following the
consummation of the transactions contemplated by the Merger Agreement (the “First Earn-Out Target”). The Escrow
Agent shall hold the other 50% of the Sponsor Earn-Out Escrow Shares until the later of (A) the Anniversary Release Date and (B) the
date on which the last sale price of the Common Stock equals or exceeds $15.00 per share (as adjusted for stock splits, stock
dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period following the
consummation of the transactions contemplated by the Merger Agreement (the “Second Earn-Out Target”). Sponsor
shall deliver to the Escrow Agent a written notice executed by Sponsor, in form reasonably acceptable to the Escrow Agent,
certifying the achievement of the First Earn-Out Target (the “First Earn-Out Target Release Notice”) and/or the
achievement of the Second Earn-Out Target (the “Second Earn-Out Target Release Notice”). The Escrow Agent shall
disburse and release to the Founders (A) 50% of the Sponsor Earn-Out Escrow Shares (and any applicable stock power), upon receipt
the First Earn-Out Target Release Notice and (B) 50% of the Sponsor Earn-Out Escrow Shares (and any applicable stock power), upon
receipt of the Second Earn-Out Target Release Notice; provided that if any of the First Earn-Out Target Release Notice or the
Second Earn-Out Target Release Notice shall be delivered prior to the Anniversary Release Date, then the Escrow Agent shall not
release any of the Sponsor Earn-Out Shares subject to such First Earn-Out Target Release Notice or the Second Earn-Out Target
Release Notice, as the case may be, until the Anniversary Release Date. In the event that neither the First Earn-Out Target Release
Notice nor the Second Earn-Out Target Release Notice is delivered on or prior to the fifth anniversary of the consummation of the
transactions contemplated by the Merger Agreement, then the Escrow Agent shall automatically disburse and release all the Sponsor
Earn-Out Escrow Shares (and any applicable stock power) to the Company for cancellation for no consideration. In the event that the
Second Earn-Out Target Release Notice is not delivered (and the First Earn-Out Target Release Notice has been delivered) on or prior
to the fifth anniversary of the consummation of the transactions contemplated by the Merger Agreement, then the Escrow Agent shall
automatically disburse and release 50% of the Sponsor Earn-Out Escrow Shares (and any applicable stock power) to the Company for
cancellation for no consideration. The Escrow Agent shall have no further duties under this Section 3.2(b)(i) with respect to
the Sponsor Earn-Out Escrow Shares after the disbursement of the Sponsor Earn-Out Escrow Shares to the Founders or the Company, as
the case may be, in accordance with this Section 3.2(b)(i).

(ii)
The Sponsor Earn-Out Escrow Shares and the Earn-Out Target shall be adjusted to reflect appropriately the effect of any stock
splits, reverse splits, stock dividends, reorganizations, reclassifications and other similar events with respect to the Common
Stock occurring on or after the date hereof and prior to the time any such Sponsor Earn-Out Escrow Shares are released to the
Founders or returned to the Company, as the case may be.


(iii)
Notwithstanding Section 3.2(b)(i), if prior to or as of the fifth anniversary of the consummation of the transactions contemplated
by the Merger Agreement, the Company undergoes a Change of Control, with the consideration or implied consideration per share of Common
Stock being (A) less than $12.00, then the Escrow Agent shall automatically disburse and release all Sponsor Earn-Out Escrow Shares not
previously released for cancellation for no consideration, (B) $12.00 or more but less than $15.00, 50% of the Sponsor Earn-Out Escrow
Shares shall be released to the Founders, and the Escrow Agent shall automatically disburse and release the other 50% of the Sponsor
Earn-Out Escrow Shares to the Company for cancellation for no consideration, and (C) $15.00 or more, all of the Sponsor Earn-Out Escrow
Shares shall be released to the Founders. Sponsor shall provide written notice (the “Sponsor Notice”) to the Escrow
Agent, with a copy to the Company, of any Change of Control that triggers the release of the Sponsor Earn-Out Escrow Shares in accordance
with this Section 3.2(b)(iii). The Escrow Agent shall disburse and release to the Founders and/or the Company the Sponsor Earn-Out
Escrow Shares (and any applicable stock power) in accordance with this Section 3.2(b)(iii) immediately prior to the consummation
of such Change of Control unless the Company shall have provided written notice to the Escrow Agent within five business days following
receipt of the Sponsor Notice objecting to such release (in which case the Escrow Agent shall hold such Sponsor Earn-Out Escrow Shares
until such time as it shall have received a joint written notice from Sponsor and the Company as to the manner in which to disburse such
Sponsor Earn-Out Escrow Shares). For purposes of this Agreement, “Change of Control” shall mean (i) the closing of
a merger, consolidation, liquidation or reorganization of the Company into or with another company or other legal person, after which
merger, consolidation, liquidation or reorganization the capital stock of the Company outstanding prior to consummation of the transaction
is not converted into or exchanged for or does not represent more than 50% of the aggregate voting power of the surviving or resulting
entity; (ii) the direct or indirect acquisition by any person (as the term “person” is used in Section 13(d)(3) or 14(d)(2)
of the Securities Exchange Act of 1934, as amended) of more than 50% of the voting capital stock of the Company, in a single or series
of related transactions; or (iii) the sale, exchange, or transfer of all or substantially all of the Company’s assets (other than
a sale, exchange, or transfer to one or more entities where the stockholders of the Company immediately before such sale, exchange or
transfer retain, directly or indirectly, at least a majority of the beneficial interest in the voting stock of the entities to which
the assets were transferred).”
