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”) to be entered
into by and between Jupiter Acquisition Corporation, a Delaware corporation (the “Company”), and Nomura Securities
International, Inc., as representative (the “Representative”) of the several underwriters named in Schedule
A thereto (the “Underwriters”), relating to an underwritten initial public offering (the “Public
Offering”), of 17,250,000 of the Company’s units (including up to 2,250,000 units that may be purchased to cover over-allotments,
if any) (each, a “Unit”), each Unit comprised of one share of the Company’s Class A common stock, par
value $0.0001 per share (the “Class A Common Stock”), and one-half of one redeemable warrant (each, a “Warrant”).
Each whole Warrant entitles the holder thereof to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to
adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”)
filed by the Company with the Securities and Exchange Commission (the “Commission”) and the Company shall apply
to have the Units listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 10 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, Jupiter Founders LLC (the “Sponsor”),
Nomura Securities International, Inc., Ladenburg Thalmann & Co. Inc. and each of the other Initial Stockholders, and each of the
undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each such other undersigned
individual, an “Insider” and collectively, the “Insiders”), hereby agrees with the
Company as follows:


 


1. The
Sponsor, each Insider and each of the other Initial Stockholders agrees that (a) 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 Common 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; and (b) if the Company engages in
a tender offer in connection with a proposed Business Combination, it, he or she shall not sell any shares of Common Stock to
the Company in connection therewith.


 


2. The
Sponsor, each Insider and each of the other Initial Stockholders hereby agrees that in the event that the Company fails to consummate
a Business Combination within 24 months from the date of the closing of the Public Offering (the latest such date being referred
to as the “Termination Date”), or such longer period approved by the Company’s stockholders in
accordance with the Company’s amended and restated certificate of incorporation (the “Certificate of Incorporation”),
the Sponsor, each Insider and each of the other Initial Stockholders 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 Class A 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, including interest earned on the funds held in the Trust Account and not
previously released to the Company to pay its taxes (which interest shall be net of taxes payable and 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
all Public Stockholders’ rights as stockholders (including the right to receive further liquidation 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 each
case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable
law. The Sponsor, each Insider and each of the other Initial Stockholders agrees not to propose any amendment to the Certificate
of Incorporation (A) to modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares
if the Company does not complete a Business Combination by the Termination Date or (B) with respect to any other provision relating
to stockholders’ rights or pre-Business Combination activity, unless the Company provides its Public Stockholders with the
opportunity to redeem their Offering Shares 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 (which interest shall be net of taxes payable) earned
on the funds in the Trust Account divided by the number of then outstanding Offering Shares.


 






     


     


    

 


The
Sponsor, each Insider and each of the other Initial Stockholders 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 held by it, him or her, provided, that the foregoing waiver shall not
apply with respect to liquidating distributions from the Trust Account made in connection with any Offering Shares purchased by
the undersigned or its affiliates during the Public Offering or on the open market after the completion of the Public Offering
if the Company fails to complete a Business Combination by the Termination Date. The Sponsor, each Insider and each of the other
Initial Stockholders hereby further waives, with respect to any shares of Common Stock held by it, him or her, if any, any redemption
rights it, he or she may have in connection with the consummation of a Business Combination, including, without limitation, any
such rights available in the context of a stockholder vote to approve such Business Combination or in the context of a tender
offer made by the Company to purchase shares of Common Stock (although the Sponsor, the Insiders, the other Initial Stockholders
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 by the Termination Date).


 


3. Notwithstanding
the provisions set forth in paragraphs 6(a) and (b) below, during the period commencing on the effective date of the Underwriting
Agreement and ending 180 days after such date, the Sponsor, each Insider and each of the other Initial Stockholders shall not,
without the prior written consent of the Representative, (i) offer, sell, contract to sell, hypothecate, pledge or grant any option
to purchase or otherwise dispose of (or enter into any transaction that 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)), 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 Common Stock, Warrants or
any securities convertible into, or exercisable, or exchangeable for, Common Stock, (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 Common Stock,
Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common 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
an intention to effect any such transaction. The provisions of this paragraph will not apply if (i) the release or waiver is effected
solely to permit a transfer of securities that is not for consideration and (ii) 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, the Sponsor (which for purposes of clarification shall not extend to any other
members or managers of the Sponsor) 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, or any claim whatsoever) to which the Company may
become subject as a result of any claim by (i) any third party (other than the Company’s independent accountants) for services
rendered or products sold to the Company or (ii) a prospective target business with which the Company has discussed entering into
a transaction agreement (a “Target”); provided, however, that such indemnification of
the Company by the Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered
(other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the
amount of funds in the Trust Account to below (i) $10.00 per share of the Offering Shares or (ii) such lesser amount per share
of the Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation
of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn
to pay taxes (less up to $100,000 of interest to pay dissolution expenses), except as to any claims by a third party (including
a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the
Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933,
as amended. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall
not be responsible to the extent of any liability for such third party claims. The Sponsor 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 Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

of its, his or her obligations under paragraphs 1, 2, 3, 4, 6(a), 6(b), and 8 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.


 


6. 
(a) The Sponsor, each Insider and each of the other Initial Stockholders agrees that it, he or she shall not Transfer any Founder

completion of the Company’s initial Business Combination and (B) subsequent to the Business Combination, (x) if the last
reported 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)
Notwithstanding the provisions set forth in paragraph 6(a), Transfers of Founder Shares (or any shares of Class A Common
Stock issuable upon the conversion thereof)
that are held by the Sponsor, any Insider, any other Initial Stockholder or any of their permitted transferees (that have complied
with this paragraph 6(b)), are permitted (i) to the Company’s officers or directors, any affiliates or family members of
any of the Company’s officers or directors, any members of the Sponsor, or any affiliates of the Sponsor, as well as affiliates
of such members and funds and accounts advised by such members; (ii) in the case of an individual, by gift to a member of the
individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family,

and distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order;
(v) by private sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection

originally purchased; (vi) in the event of the Company’s liquidation prior to the completion of the Company’s initial
Business Combination; (vii) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement
upon dissolution of the Sponsor or any other Initial Stockholder; (viii) 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 completion of the
Company’s initial Business Combination; or (ix) in the case of any Initial Stockholder that is, or is affiliated with, an
Underwriter, to such Initial Stockholder’s affiliates or any entity controlled by such Initial Stockholder, provided,
however, that in the case of clauses (i) through (v), (vii) or (ix), these permitted transferees must enter into a written
agreement agreeing to be bound by these transfer restrictions and the other restrictions contained herein.
