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 or proposed to be entered into by and among Mercato Partners Acquisition Corporation, a Delaware corporation (the “Company”), and BofA Securities, Inc., as the underwriter (the
“Underwriter”), relating to an underwritten initial public offering (the “Public Offering”) of up to 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 (“Common Stock”), and one-half
of one redeemable warrant (each, a “Warrant”). Each whole 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 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”) and the
Company has applied to have the Units listed on The Nasdaq Global Select Market. Certain capitalized terms used herein are defined in paragraph 11 hereof. 

In order to induce the Company and the Underwriter 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, Mercato Partners Acquisition Group, LLC (the “Sponsor”) and the undersigned individuals, each of whom is a member of the
Company’s board of directors, a nominee for membership on the Company’s board of directors and/or a member of the Company’s management team (each, an “Insider” and collectively, the “Insiders”),
hereby agrees, severally but not jointly, 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 seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider
agrees that it, he or she will not sell or tender any shares of Common Stock owned by it, him or her in connection therewith. 












 2. The Sponsor and each Insider hereby agrees that in the event that the Company fails to
consummate a Business Combination within 15 months from the closing of the Public Offering, or the three-month period in accordance with the Company’s second amended and restated certificate of incorporation (an “Extension
Period”), 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 ten
(10) business days thereafter, 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, including interest earned on the funds held in the Trust Account (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 of the Company (including the right to receive further liquidation distributions, if any), 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 and each Insider agrees not to propose any amendment to the Company’s certificate of incorporation to modify the substance or timing of the Company’s obligation to allow
redemption 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 15 months from the closing of the Public Offering or Extension
Period or with respect to any other provision relating to the rights of holders of the Common Stock or pre-initial Business Combination activity, unless the Company provides 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 taxes payable and less up to $100,000 of interest to pay dissolution expenses), 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 held by it. The Sponsor and each Insider 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 (A) 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 (B) in the context of a tender offer made by the Company to purchase shares of Common Stock, or in connection with a stockholder vote to approve an amendment to the Company’s certificate of incorporation
(i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company has not consummated a Business
Combination within 15 months from the closing of the Public Offering or Extension Period or (ii) with respect to any other provision relating to the rights of holders of the Common Stock or pre-initial
Business Combination activity (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 15 months from the date of the closing of the Public Offering or Extension Period).

 3. Notwithstanding the provisions set forth in paragraphs 7(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 and each Insider 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 Common Stock, Founder Shares, Warrants or any securities convertible into, or exercisable, or exchangeable
for, any Units, Common Stock, Founder Shares, or Warrants, or publicly disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other arrangement that transfers, in whole or in part, any of the economic
consequences of ownership of any Units, shares of Common Stock, Founder Shares, or Warrants or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of units or such other
securities, in cash or otherwise; provided, however, 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 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 (“Section 16”), is triggered as a result of such transfer, any related Section 16 filing includes a practical explanation of the transfer). 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 a Business Combination within 15 months from the date of the closing of the Public Offering or any Extension Period, the Sponsor (which for purposes of clarification shall not extend to any other stockholders,
members or managers of the Sponsor, or any of the other undersigned) 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 registered public accounting firm) 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 registered public accounting firm) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.15 per Offering Share or (ii) such lesser amount per Offering
Share 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 due to reductions in the value of the trust assets, in each case, net of the amount of interest earned on the
property in the Trust Account which may be withdrawn to pay the Company’s taxes, except as to any claims by a third party 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 Underwriter against certain liabilities, including 

  
 3 













 
liabilities under the Securities Act. 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. 
 5. To the extent that the Underwriter does not
exercise its over-allotment option to purchase up to an additional 750,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees that it shall forfeit, at no cost, its 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 Underwriter upon the exercise of its 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 Underwriter so that the number of Founder Shares will represent an aggregate of 20.0% of the Company’s issued and
outstanding shares of Capital Stock after the Public Offering (not including shares of Common Stock underlying the Warrants or the Private Placement Warrants). The Initial Stockholders further agree that to the extent that the size of the Public
Offering is increased or decreased, the Founder Shares will automatically convert into Common Stock at the time of the initial Business Combination at a ratio such that the number of Common Stock issuable upon conversion of all Founder Shares will
equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of all shares of Capital Stock issued and outstanding upon completion of this offering, plus (ii) the total
number of Common Stock issued or deemed issued or issuable upon conversion or exercise of any Equity-Linked Securities (as defined herein) or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the
initial Business Combination, excluding any Common Stock or Equity-Linked securities exercisable for or convertible into shares of Common Stock issued, deemed issued or to be issued, to any seller in the initial Business Combination and any Private
Placement Warrants issued to the Sponsor, its affiliates or any member of the Company’s management team upon conversion of working capital loans. 

6. The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriter and the Company may be irreparably injured in the
event of a breach by such Sponsor or Insider of its, or his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), 7(b), 8 and 9 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 seek 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 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 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, 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 Warrants (or shares of Common Stock issued
or issuable upon the exercise of the Private Placement Warrants), until 30 days after the completion of a Business Combination (the “Private Placement Warrants 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 (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 the Sponsor, any Insider or any of their permitted
transferees (that have complied with this paragraph 7(c)), are permitted (a) 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; (b) 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 or an affiliate of such
person, or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the 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 a 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 its initial Business Combination; (g) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement, as amended, upon dissolution of the Sponsor; or (h) in the event of
the Company’s completion of a liquidation, merger, 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 a Business Combination; provided, however, that in the case of clauses (a) through (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 undersigned’s background. Each Insider’s questionnaire furnished to the Company and the Underwriter is true and accurate
in all respects. Each Insider represents and warrants that: such Insider 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; such Insider 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 is not currently a defendant in any such criminal proceeding. 

9. Except as disclosed in, or expressly contemplated by, the Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor
or any Insider, nor any director or officer 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). 

  
 5 













 10. The Sponsor and each Insider has full right and power, without violating any agreement
to which it is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter
Agreement and, as applicable, to serve as an officer and/or a director on the board of directors of the Company, as applicable, and hereby consents to being named in the Prospectus as an officer and/or director of the Company, as applicable.

Placement Warrants” shall mean the Warrants to purchase shares of Common Stock of the Company that the Sponsor has agreed to purchase for an aggregate purchase price of $9,000,000 in the aggregate (or $10,050,000 if the over-allotment option is
exercised in full) in a private placement that shall occur simultaneously with the consummation of the Public Offering; (vii) “Public Stockholders” shall mean the holders of securities issued in the Public Offering; (viii) “Trust
