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”), dated December 9,
2021, entered into by and between Southport Acquisition Corporation, a Delaware corporation (the “Company”), and BofA
Securities, Inc. (the “Underwriter”), relating to the underwritten initial public offering (the “Public
Offering”) of 23,000,000 of the Company’s units (including 3,000,000 units that were purchased to cover over-allotments)
(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 one-half of one redeemable warrant (each, a “Public Warrant”). Each
whole Public Warrant entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment
as described in the Prospectus (as defined below). The Units were sold in the Public Offering pursuant to a registration statement on
Form S-1 and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission
(the “Commission”) and listed on the New York Stock Exchange. Certain capitalized terms used herein are defined in
paragraph 11 hereof.


 


For good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the undersigned individuals, each of whom was elected a member of the board of directors
of the Company (each, a “Director” and collectively, the “Directors”) on the date hereof hereby
severally (and not jointly and severally) agrees with the Company as follows:


 


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


 






     


    


    

 


2.          Each
Director hereby agrees that in the event that the Company fails to consummate a Business Combination within 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 may be amended (the “Charter”)(any such later period that is approved,
the “Extension Period”), he or she 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 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 (net of amounts withdrawn to pay the Company’s taxes (“Permitted
Withdrawals”) and 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 of the Company (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 each case to the Company’s obligations under Delaware law to provide for claims of creditors
and other requirements of applicable law. Each Director agrees not to propose any amendment to the Charter (i) to modify the substance
or timing of the Company’s obligation to provide holders of Offering Shares the right to have their Offering Shares redeemed in
connection with the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company does not complete
a Business Combination within 18 months from the closing of the Public Offering or (ii) with respect to any other provision
relating to stockholders’ rights or pre-initial Business Combination activity, unless, in each case, 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 earned on the funds held in the Trust Account
(net of Permitted Withdrawals), divided by the number of then outstanding Offering Shares.


 


Each Director acknowledges that, with respect to
the Founder Shares held by him or her, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust
Account as a result of any liquidation of the Company. Each Director hereby further waives, with respect to any shares of Capital Stock
held by him or her, if any, any redemption rights 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 Directors and their respective affiliates shall
be entitled to redemption and liquidation rights with respect to any Offering Shares they hold if the Company fails to consummate a Business
Combination within the 18 months from the closing of the Public Offering or during any Extension Period) or in connection with a
stockholder vote to approve an amendment to the Charter to modify the substance or timing of the Company’s obligation to provide
holders of Offering Shares the right to have their Offering Shares redeemed or to redeem 100% of the Offering Shares if the Company does
not complete a Business Combination within the 18 months from the closing of the Public Offering or with respect to any other material
provision relating to stockholders’ rights or pre-initial Business Combination activity.


 






     


    


    

 


3.          During
the period commencing on the date hereof and ending 180 days after the effective date of the Underwriting Agreement, each Director
shall not, without the prior written consent of the Underwriter, (i) offer, pledge, sell, contract
to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase,
lend or otherwise transfer or dispose of, directly or indirectly, or file with, or submit to, the Commission a registration statement
under the Securities Act of 1933, as amended (the “Securities Act”) relating to any Units, shares of Capital Stock,
Warrants or any securities convertible into, or exercisable, or exchangeable for, any Units, shares of Capital Stock or Warrants, or publicly
disclose the intention to undertake any of the foregoing or (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, Units, shares of Capital Stock or Warrants owned by him or her, whether any such
transaction described in clause (i) or (ii) above is to be settled by delivery of such securities, in cash or otherwise; provided,
however, that the foregoing shall not apply to the forfeiture of any Founder Shares pursuant to their terms or any transfer of
Founder Shares to current or future independent directors of the Company (as long as such current or future independent director is or
becomes subject to the terms of this Letter Agreement with respect to such Founder Shares at the time of such transfer; and, as long as,
to the extent any reporting obligation under Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”) is triggered as a result of such transfer, any related filing under Section 16 of the Exchange Act includes a practical
explanation of the transfer).


 


4.          Each
Director hereby agrees and acknowledges that: (i) the Underwriter and the Company would be irreparably injured in the event of a
breach by such Director of his or her obligations under paragraphs 1, 2, 3, 5(a), 5(b), and 7, 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.


 


5.          (a)          Each Director agrees that he or she shall not Transfer any Founder Shares (or shares of Common Stock issuable upon conversion thereof)
until the earlier 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 closing 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 completion of 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)          Each
Director agrees that he or she shall not Transfer any 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 Company’s initial Business Combination
(the “Private Placement Warrants Lock-up Period,” together with the Founder Shares Lock-up Period, the “Lock-up
Periods”).


 






     


    


    

 


(c)          Notwithstanding
the provisions set forth in paragraphs 3 and 5(a) and (b), Transfers of the Founder 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 and that are
held by any Director or any of his or her permitted transferees (that have complied with this paragraph 5(c)), are permitted (i) to
the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, Southport
Acquisition Sponsor LLC (the “Sponsor”), any members of the Sponsor, or any affiliates of the Sponsor; (ii) in the case
of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of
the individual’s immediate family or an affiliate of such individual, or to a charitable organization; (iii) in the case of
an individual, by virtue of the laws of descent 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 the consummation of the
Company’s initial Business Combination at prices no greater than the price at which the Founder Shares, Private Placement Warrants
or the shares of Common Stock, as the case may be, were originally purchased; (vi) in the event of the Company’s liquidation
prior to the completion of its 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; (viii) in the event of the Company’s completion of a 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 Capital Stock for cash, securities or other property subsequent to the Company’s completion
of its initial Business Combination; or (ix) to a nominee or custodian of a person or entity to whom a disposition or transfer would
be permissible under clauses (i) through (viii) above; provided, however, that in the case of clauses (i) through
(v) and (ix), 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.


 


6.          Each
Director represents and warrants that 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 Director’s
biographical information furnished to the Company is true and accurate in all respects and does not omit any material information with
respect to such Director’s background. Each Director represents and warrants that: 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; 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 he or she is not currently a defendant in any such criminal proceeding.


 


7.          Except
as disclosed in the Prospectus, neither the Sponsor nor any Director nor any affiliate of the Sponsor or any Director shall receive from
the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation
for services rendered to the Company prior to or in connection with 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: payment to the Sponsor of a total of $15,000 per month for
office space, utilities, and secretarial and administrative services; repayment of a loan and advances of up to $350,000 made to the Company
by the Sponsor to cover expenses related to the organization of the Company and the Public Offering; reimbursement for any out-of-pocket
expenses related to identifying, investigating and consummating the Company’s initial Business Combination; and repayment of loans,
if any, and on such terms as to be determined by the Company from time to time, made by the Sponsor or an affiliate of the Sponsor or
certain of the Company’s officers and directors to fund working capital deficiencies or finance transaction costs in connection
with an intended initial Business Combination, provided, that, if the Company does not consummate an initial Business Combination,
a portion of the working capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no
proceeds from the Trust Account are used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants of the post
Business Combination entity at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the Private
Placement Warrants, including as to exercise price, exercisability and exercise period.

the Company.

11.          Except
