	Re:	Initial
Public Offering

 

Ladies
and Gentlemen:

 

This
letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting
Agreement”) entered into by and among Twelve Seas Investment Company IV TMT, a Delaware corporation (the “Company”),
and Mizuho Securities USA LLC, as representative (the “Representative”) of the several underwriters (each, an “Underwriter”
and collectively, the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”),
of 23,000,000 of the Company’s units (including up to 3,000,000 units that may be purchased to cover over-allotments, if any) (the
“Units”), each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the
“Common Stock”), and three-fourths of one redeemable warrant. Each whole warrant (each, a “Warrant”)
entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment. The Units will
be sold in the Public Offering pursuant to a registration statement on Form S-1 (File No. 333-               )
and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”)
and the Company has applied to have the Units listed on The Nasdaq Global Market. Certain capitalized terms used herein are defined in
paragraph 11 hereof.

 

In
order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and
for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of Twelve Seas Sponsor
IV TMT LLC (the “Sponsor”) and the undersigned individuals, each of whom is a member of the Company’s board
of directors and/or management team (each, an “Insider” and collectively, the “Insiders”),
hereby agrees with the Company as follows:

 

1.
The Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in
connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it, him or her
in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection
with such stockholder approval. If the Company engages in a tender offer in connection with any proposed Business Combination, the
Sponsor and each Insider agrees that it, he or she will not seek to sell or tender any shares of Capital Stock owned by it, him or
her to the Company in connection with such tender offer.

 

     

     

    

 

2.
The Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination 18 months
from the closing of the Public Offering, or such later period approved by the Company’s stockholders in accordance with the
Company’s amended and restated certificate of incorporation (as it may be amended from time to time, the
“Charter”), the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all
operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days
thereafter, subject to lawfully available funds therefor, redeem 100% of the shares of Common Stock sold as part of the Units in the
Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount
then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the Trust Account and not
previously released to the Company to pay its taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the
number of then outstanding Offering Shares, which redemption will completely extinguish the rights of all holders of Offering Shares
as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as
promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and
the Company’s board of directors, dissolve and liquidate, subject in the case of clauses (ii) and (iii) to the Company’s
obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. The Sponsor and each
Insider agrees not to propose any amendment to the Charter to modify (i) the substance or timing of the ability of holders of
Offering Shares to seek redemption in connection with the Company’s initial Business Combination or amendments to the Charter
prior thereto or (ii) (A) the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete its
initial Business Combination within such time set forth in the Charter or (B) with respect to any other provision relating to
stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the holders of the Offering
Shares with the opportunity to redeem their shares of Common Stock upon approval of any such amendment at a per-share price, payable
in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the
Trust Account and not previously released to the Company to pay its taxes, divided by the number of then outstanding Offering
Shares.

 

The
Sponsor and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held
in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares
or Private Placement Shares held by it, him or her. The Sponsor and each Insider hereby further waives, with respect to any shares of
Common Stock held by it, him or her, if any, whether acquired now or hereafter, any redemption rights it, he or she may have in connection
with the consummation of a Business Combination or amendments to the Charter prior thereto, including, without limitation, any such rights
available in the context of a stockholder vote to approve such Business Combination or a stockholder vote to approve an amendment to
the Charter to modify (i) (A) the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the
Company has not consummated a Business Combination within the time period set forth in the Charter or (B) any other provisions relating
to stockholders’ rights or pre-initial Business Combination activity or (ii) in the context of a tender offer made by the Company
to purchase shares of Common Stock (although the Sponsor, the Insiders and their respective affiliates shall be entitled to redemption
and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business Combination
within the time period set forth in the Charter).

 

    2

     

    

 

3.   During
the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider
shall not, without the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to sell, hypothecate,
pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, 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 Securities Exchange
Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder,
with respect to any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for,
shares of Capital Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another, in whole or
in part, any of the economic consequences of ownership of any Units, shares of Capital Stock, Warrants or any securities convertible
into, or exercisable, or exchangeable for, shares of Capital Stock owned by it, him or her, whether any such transaction is to be settled
by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in
clause (i) or (ii). Each of the Insiders and the Sponsor acknowledges and agrees that, prior to the effective date of any release or
waiver, of the restrictions set forth in this paragraph 3 or paragraph 7 below, the Company shall announce the impending release or waiver
by press release through a major news service at least two business days before the effective date of the release or waiver. Any release
or waiver granted shall only be effective two business days after the publication date of such press release. The provisions of this
paragraph will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has
agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms
remain in effect at the time of the transfer.

 

4.   In
the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within
the time period set forth in the Charter, the Sponsor (the “Indemnitor”) agrees to indemnify and hold harmless the
Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or
other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened) to
which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company
or (ii) any prospective target business with which the Company has entered into a written letter of intent, confidentiality or other
similar agreement or Business Combination agreement (a “Target”); provided, however, that such indemnification of
the Company by the Indemnitor shall (x) apply only to the extent necessary to ensure that such claims by a third party or a Target do
not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.20 per Offering Share and (ii) the actual amount per
Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.20 per Offering Share
is then held in the Trust Account due to reductions in the value of the trust assets, less interest earned on the Trust Account which
may be withdrawn to pay taxes, (y) not apply to any claims by a third party or a Target which executed a waiver of any and all rights
to the monies held in the Trust Account (whether or not such waiver is enforceable) and (z) not apply to any claims under the Company’s
indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The Indemnitor
shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15
days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall
undertake such defense.

 

    3

     

    

 

5.  To
the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 3,000,000 Units in full
within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost,
a number of Founder Shares in the aggregate equal to 750,000 multiplied by a fraction, (i) the numerator of which is 3,000,000 minus
the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which
is 3,000,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters
so that the Sponsor will be required to forfeit only that number of Founder Shares as is necessary so that the Initial Stockholders will
own an aggregate of 20.0% of the Company’s issued and outstanding shares of Capital Stock after the Public Offering (not including
the Private Placement Shares or the Representative Shares).

 

6.   The
Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the
event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), 7(b), and 9, as
applicable, of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching
party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event
of such breach.

 

7.   (a)
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or shares of Common Stock issuable upon
conversion thereof) until the earlier to occur of (A) one year after the completion of the Company’s initial Business Combination
and (B) subsequent to the Company’s initial Business Combination, (x) if the reported last sale price of the Common Stock equals
or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any
20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination,
or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction
that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities
or other property (the “Founder Shares Lock-up Period”).

 

(b)    The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Units, the Private Placement Shares, the
Private Placement Warrants or shares of Common Stock issued or issuable upon the exercise of the Private Placement Warrants, until 30
days after the completion of the initial Business Combination (the “Private Placement Units Lock-up Period”, together
with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 

    4

     

    

 

(c)   Notwithstanding
the provisions set forth in paragraphs 7(a) and 7(b), Transfers of the Founder Shares, Private Placement Units, Private Placement Shares,
Private Placement Warrants and shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants
or the Founder Shares that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph
7(c)), are permitted (i) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers
or directors or any members of the Sponsor or any affiliates of the Sponsor; (b) in the case of an individual, by gift to a member of
such individual’s immediate family or to a trust, the beneficiary of which is a member of such individual’s immediate family,
an affiliate of such individual or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution
upon death of such individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales
or transfers made in connection with the consummation of an initial Business Combination at prices no greater than the price at which
the securities were originally purchased; (f) in the event of the Company’s liquidation prior to the completion of an initial Business
Combination; (g) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution
of the Sponsor; or (h) in the event of the Company’s liquidation, merger, capital stock exchange, reorganization or other similar
transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash,
securities or other property subsequent to the Company’s completion of an initial Business Combination; provided, however,
that in the case of clauses (a) through (e) or (g), these permitted transferees must enter into a written agreement with the Company
agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Agreement (including provisions
relating to voting, the Trust Account and liquidating distributions).

 

8.   The
Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in any securities
or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each
Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true
and accurate in all respects and does not omit any material information with respect to the Insider’s background. Each Insider’s
questionnaire furnished to the Company is true and accurate in all respects. Each Insider represents and warrants that: it, he or she
is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or
refrain from any act or practice relating to the offering of securities in any jurisdiction; it, he or she has never been convicted of,
or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person,
or (iii) pertaining to any dealings in any securities and it, he or she is not currently a defendant in any such criminal proceeding.

 

9.   Except
as disclosed in the Prospectus, neither the Sponsor nor any officer or director of the Company nor any affiliate of the Sponsor nor any
affiliate of any officer or director of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting
fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order
to effectuate, the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is),
other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial
Business Combination: repayment of up to an aggregate of $300,000 in loans made to the Company by the Sponsor to cover offering-related
and organizational expenses; payment to an affiliate of the Sponsor of $10,000 per month, for up to 18 months, for office space, utilities
and secretarial and administrative support; reimbursement for any reasonable out-of-pocket expenses related to identifying, investigating
and completing an initial Business Combination; and repayment of non-interest bearing loans which may be made by the Sponsor or an affiliate
of the Sponsor or certain of the Company’s officers and directors to finance transaction costs in connection with an intended initial
Business Combination, the terms of which (other than as described above) have not been determined nor have any written agreements been
executed with respect thereto. Up to $1,500,000 of such loans may be convertible into units, at a price of $10.00 per unit at the option
of the lender, upon consummation of the initial Business Combination. The units would be identical to the Private Placement Units.

effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties
hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall
be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and venue,
which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts
represent an inconvenient forum.

Hundred Thousand Dollars ($300,000) in lawful money of the United States of America, on the terms and conditions described below. All
payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker
to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

 

1. Principal. The principal balance of this
Note shall be payable by the Maker on the earlier of: (i) December 31, 2021 or (ii) the date on which Maker consummates an initial public
offering of its securities. The principal balance may be prepaid at any time. Under no circumstances shall any individual, including but
not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities
of the Maker hereunder.

 

2. Interest. No interest shall accrue on the
unpaid principal balance of this Note.

 

3. Drawdown Requests. Maker and Payee agree
