**Item 1.01 Entry into a Material Definitive Agreement.**

In connection with the special meeting of the stockholders (the "Special Meeting") of Atlantic Coastal Acquisition Corp., a Delaware Corporation (the "Company"), to extend the date by which the Company has to consummate a business combination (the "Extension") from March 8, 2023 to June 8, 2023 (or later, pursuant to the terms of the Extension), the Company and Atlantic Coastal Acquisition Management LLC (the "Sponsor"), will enter into a non-redemption agreement (the "Non-Redemption Agreement") with one or more unaffiliated third party or parties, pursuant to which such third party or third parties will agree not to redeem Class A common stock of the Company ("Non-Redeemed Shares") in connection with the Extension. In exchange for the foregoing commitments not to redeem such Class A common stock, the Sponsor has agreed to transfer Class B common stock of the Company held by the Sponsor to such third party or third parties immediately following consummation of an initial business combination if they continue to hold such Non-Redeemed Shares through the Special Meeting. The Non-Redemption Agreements will increase the amount of funds that remain in the Company's trust account following the Extension Meeting.

The foregoing summary of the Non-Redemption Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Non-Redemption Agreement filed herein as Exhibit 10.1 and incorporated herein by reference

**Exhibit 10.1**

**NON-REDEMPTION AGREEMENT AND ASSIGNMENT OF ECONOMIC INTEREST**

This Non-Redemption Agreement and Assignment of Economic Interest (this "<u>Agreement</u>") is entered as of February 27, 2023 by and among Atlantic Coastal Acquisition Corp. ("<u>ACAH</u>"), Atlantic Coastal Acquisition Management LLC, a Delaware limited liability company (the "<u>Sponsor</u>") and the undersigned investors (collectively, the "<u>Investor</u>").

**RECITALS**

**WHEREAS**, the Sponsor currently holds ACAH Class B common stock initially purchased in a private placement prior to ACAH's initial public offering (the "<u>Founder Shares</u>");

**WHEREAS**, ACAH expects to hold a special meeting of stockholders (the "<u>Meeting</u>") for the purpose of approving, among other things, an amendment to ACAH's Amended and Restated Certificate of Incorporation (the "<u>Charter</u>") to extend the date by which ACAH must consummate an initial business combination (the "<u>Initial Business Combination</u>") by at least three additional months until June 8, 2023 (the "<u>Extension</u>");

**WHEREAS**, the Charter provides that a stockholder of ACAH may redeem shares of Class A common stock, par value $0.0001 per share (the "<u>Class A common stock</u>"), that were initially sold as part of the units in ACAH's initial public offering (whether they were purchased in our initial public offering or thereafter in the open market) (the "<u>Public Shares</u>" and together with the Founder Shares including any Class A common stock not sold initially as part of the units in ACAH's initial public offering, the "<u>Common stock</u>") in connection with the Charter amendment, on the terms set forth in the Charter ("<u>Redemption Rights</u>");

**WHEREAS**, subject to the terms and conditions of this Agreement, the Sponsor desires to transfer to Investor, and Investor desires to acquire from the Sponsor, that number of Founder Shares set forth opposite such Investor's name on <u>Exhibit A</u> (the "<u>Assigned Securities</u>"), to be transferred to Investor in connection with ACAH's completion of its Initial Business Combination, and, prior to the transfer of the Assigned Securities to Investor, the Sponsor desires to assign the economic benefits of the Assigned Securities to Investor.

**NOW THEREFORE**, in consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Investor and the Sponsor hereby agree as follows:

1. <u>Terms of Transfer</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.1 Upon the terms and subject to the conditions of this Agreement, the Sponsor agrees that if (a) as of 5:30 PM, New York time, on the
date of the Meeting, Investor holds the Investor Shares (as defined below), (b) Investor does not exercise its Redemption Rights with
respect to such Investor Shares in connection with the Meeting, and (c) the Extension is approved at the Meeting and the Company meets
the continued or initial listing financial requirements to be listed on a National Securities Exchange following the Meeting, then the
Sponsor hereby agrees to assign to Investor for no additional consideration the Assigned Securities set forth on <u>Exhibit A</u>, and
the Sponsor agrees to assign to Investor the Economic Interest (as defined below) associated with the Assigned Securities that the Sponsor
has agreed to assign to Investor. "Investor Shares" shall mean the lesser of (i) 200,000 Public Shares, and (ii) 9.9% of the
Class A common stock outstanding after the Meeting (including those Public Shares subject to non-redemption agreements with other ACAH
stockholders similar to this Agreement on or about the date of the Meeting), after giving effect to all redemptions of Class A common
stock in connection with the Meeting. The Sponsor and ACAH agree to provide Investor with the final number of Investor Shares subject
to this Agreement no later than 9:30 a.m. Eastern on the first business day following the end of the Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.2 The Sponsor and Investor hereby agree that the assignment of the Assigned Securities shall be subject to the conditions that (i) the
Initial Business Combination is consummated; and (ii) Investor (or its Permitted Transferees (as such term is defined in that certain
Letter Agreement, dated March 3, 2021, by and among the Company, the Sponsor and the Company's officers and directors (as it exists
on the date hereof, the " <u>Letter Agreement</u> ") executes a joinder to the Letter Agreement. Upon
the satisfaction of the foregoing conditions, as applicable, the Sponsor shall promptly transfer the Assigned Securities to Investor (or
its Permitted Transferees). The Sponsor covenants and agrees to facilitate such transfer to Investor (or its Permitted Transferees) in
accordance with the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.3 <u>Adjustment to Share Amounts</u>. If at any time the number of outstanding Founder Shares is increased or decreased by a consolidation,
combination, subdivision or reclassification of the Common stock of ACAH or other similar event, then, as of the effective date of such
consolidation, combination, subdivision, reclassification or similar event, all share numbers referenced in this Agreement shall be adjusted
in proportion to such increase or decrease in the Common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.4 <u>Merger or Reorganization, etc</u>. If there shall occur any reorganization, recapitalization, reclassification, consolidation or
merger involving ACAH in which its Common stock are converted into or exchanged for securities, cash or other property, then, following
any such reorganization, recapitalization, reclassification, consolidation or merger, in lieu of common stock of ACAH, the Sponsor shall
transfer, with respect to each Founder Share to be transferred hereunder, upon the Sponsor's receipt thereof, the kind and amount
of securities, cash or other property into which such Assigned Securities converted or exchanged; and the Economic Interest shall be with
respect to such kind and amount of securities, cash or other property.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.5 <u>Forfeitures, Transfers, etc</u>. Investor shall not be required to forfeit or transfer the Assigned Securities. Investor acknowledges
that, pursuant to the Amended and Restated Limited Liability Company Agreement of the Sponsor (as it exists on the date hereof, the " <u>Sponsor LLC Agreement</u> "), prior to, or at the time of, the Initial Business Combination, the managers of the Sponsor have the authority
to cause the Sponsor to subject the Founder Shares to earn-outs, forfeitures, transfers or other restrictions, or amend the terms under
which the Founder Shares were issued or any restrictions or other provisions relating to the Founder Shares set forth in the instruments
establishing the same (including voting in favor of any such amendment) or enter into any other arrangements with respect to the Founder
Shares, and that the managers are authorized to effectuate such earn-outs, forfeitures, transfers, restrictions, amendments or arrangements,
including arrangements relating to the relaxation or early release of restrictions, in such amounts and pursuant to such terms as they
determine in their sole and absolute discretion for any reason. Sponsor acknowledges and agrees that any such earn-outs, forfeitures,
transfers, restrictions, amendments or arrangements shall apply only to the Founder Shares other than the Assigned Securities and the
terms and conditions applicable to the Assigned Securities shall not be changed as a result of any such earn-outs, forfeitures, transfers,
restrictions, amendments or arrangements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.6 <u>Delivery of Shares; Other Documents</u>. At the time of the transfer of Assigned Securities hereunder, the Sponsor shall deliver
the Assigned Securities to Investor by transfer of book-entry shares effected through ACAH's transfer agent. The parties to this
Agreement agree to execute, acknowledge and deliver such further instruments and to do all such other acts, as may be necessary or appropriate
to carry out the purposes and intent of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.7 <u>Assignment of Registration Rights</u>. Concurrent with the transfer of Assigned Securities to Investor under this Agreement, the
Sponsor hereby assigns all of its rights, duties and obligations to Investor with respect to the Assigned Securities under that certain
Registration Rights Agreement, dated March 3, 2021, by and among the Company and the Sponsor (as it exists on the date of the Agreement,
the " <u>Registration Rights Agreement</u> "), and hereby represents and confirms to Investor that, upon Investor's receipt
of the Assigned Securities, (i) Investor shall be a "Holder" under the Registration Rights Agreement and (ii) the
Assigned Securities shall be "Registrable Securities" under the Registration Rights Agreement. This Agreement constitutes
the Sponsor's written notice to ACAH of such assignment in accordance with the Registration Rights Agreement. Investor and ACAH
shall execute the Joinder (as defined below) pursuant to which Investor will be bound by the terms and provisions of the Registration
Rights Agreement as a "Holder" thereunder with respect to the Assigned Securities (upon acquisition thereof) as "Registrable
Securities" thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.8 <u>Joinder to Letter Agreement</u>. In connection with the transfer of the Assigned Securities to Investor, Investor shall execute
a joinder to the Letter Agreement and the Registration Rights Agreement in substantially the form attached here to as <u>Exhibit B</u> (the " <u>Joinder</u> ") pursuant to which Investor shall agree with ACAH to be bound solely by Section 8 of the Letter Agreement
solely with respect to the Assigned Securities. Notwithstanding anything in this Agreement or the Joinder to the contrary, Investor shall
be released with respect to the Assigned Securities from any transfer or lock-up restrictions under the Letter Agreement or Registration
Rights Agreement to the same extent as any other holder of Founder Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.9 <u>Termination</u>. This Agreement and each of the obligations of the undersigned shall terminate on earlier of (a) the failure of
ACAH's stockholders to approve the Extension at the Meeting, (b) the fulfillment of all obligations of parties hereto, (c) the liquidation
or dissolution of ACAH, (d) the mutual written agreement of the parties hereto; or (e) if Investor exercises its Redemption Rights with
respect to any Investor Shares in connection with the Meeting and such Redemption Rights are not withdrawn prior to 5:00 p.m., Eastern
Time, on February 28, 2023. Notwithstanding any provision in this Agreement to the contrary, the Sponsor's obligation to transfer
the Assigned Securities to Investor shall be conditioned on (i) the satisfaction of the conditions set forth in Section 1.2 and (ii) Investor
not exercising its Redemption Rights with respect to such Investor Shares in connection with the Meeting.

2. <u>Assignment of Economic Interest</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1 Upon satisfaction of the conditions set forth in Section 1.1, the Sponsor hereby assigns to Investor all of its economic right, title
and interest in and to that number of Assigned Securities set forth on <u>Exhibit A</u> (the " <u>Economic Interest</u> "),
subject to adjustment as set forth in Section 2.2. The Economic Interest represents the Sponsor's right to receive dividends and
other distributions made by the Sponsor pursuant to the Sponsor LLC Agreement allocated to that number of Assigned Securities set forth
on <u>Exhibit A</u> represented by the Founder Shares held directly by the Sponsor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2 If at any time the number of outstanding ordinary shares of ACAH is increased or decreased by a consolidation, combination, split
or reclassification or other similar event (other than the conversion of Founder Shares to shares of Class A common stock), then, as of
the effective date of such consolidation, combination, split, reclassification or similar event, the number of shares underlying the Economic
Interest shall be adjusted in proportion to such increase or decrease in outstanding ordinary shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3 Investor acknowledges and agrees that it has no right to vote on matters of the Sponsor as a result of the Assigned Securities or
Economic Interest, or to vote with respect to any Assigned Securities, and it has no right to vote Assigned Securities prior to transfer
of any such shares to Investor pursuant to this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4 Investor acknowledges and agrees that if it has a right pursuant to its Economic Interest to receive any dividends or other distributions
paid in Common stock or other non-cash property, the Sponsor shall transfer all of its right, title and interest in such dividends or
distributions concurrently with the transfer of the Assigned Securities to such Investor pursuant to Section 1.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.5 If the conditions to the transfer of the Founder Shares in Section 1 are not satisfied with respect to any Founder Shares, then Investor
shall automatically assign its Economic Interests in such Founder Shares back to the Sponsor, for no consideration.

3. <u>Representations and Warranties of Investor</u>. Investor represents and warrants to, and agrees with, the Sponsor that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1 <u>No Government Recommendation or Approval</u>. Investor understands that no federal or state agency has passed upon or made any
recommendation or endorsement of the offering of the Assigned Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2 <u>Accredited Investor</u>. Investor is an "accredited investor" as such term is defined in Rule 501(a) of Regulation
D under the Securities Act of 1933, as amended (the " <u>Securities Act</u> "), and acknowledges that the sale contemplated
hereby is being made in reliance, among other things, on a private placement exemption to "accredited investors" under the
Securities Act and similar exemptions under state law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3 <u>Intent</u>. Investor is acquiring the Assigned Securities solely for investment purposes, for such Investor's own account
(and/or for the account or benefit of its members or affiliates, as permitted), and not with a view to the distribution thereof in violation
of the Securities Act and Investor has no present arrangement to sell Assigned Securities to or through any person or entity except as
may be permitted hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4 <u>Restrictions on Transfer; Trust Account; Redemption Rights</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.1 Investor acknowledges and agrees that, prior to their transfer hereunder, the Assigned Securities are, and following any transfer
to Investor may continue to be, subject to the transfer restrictions and certain other restrictions as set forth in the Letter Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.2 Investor acknowledges and agrees that the Assigned Securities are not entitled to, and have no right, interest or claim of any kind
in or to, any monies held in the trust account into which the proceeds of ACAH's initial public offering were deposited (the " <u>Trust Account</u> ") or distributed as a result of any liquidation of the Trust Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.3 Investor agrees, solely for the benefit of and, notwithstanding anything else herein, enforceable only by the Company, to waive any
right that it may have to elect to have ACAH redeem any Investor Shares and agrees not to redeem or otherwise exercise any right to redeem,
the Investor Shares and to reverse and revoke any prior redemption elections made with respect to the Investor Shares in connection with
the Extension. For the avoidance of doubt, nothing in this Agreement is intended to restrict or prohibit Investor's ability to redeem
any Public Shares other than the Investor Shares, or to trade or redeem any Public Shares (other than the Investor Shares) in its discretion
and at any time or any Investor Shares in its discretion and at any time after the date of the Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.4 Investor acknowledges and understands the Assigned Securities are being offered in a transaction not involving a public offering in
the United States within the meaning of the Securities Act and have not been registered under the Securities Act and, if in the future
Investor decides to offer, resell, pledge or otherwise transfer Assigned Securities, such Assigned Securities may be offered, resold,
pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant
to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant to any other available
exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws
of any state or any other jurisdiction. Investor agrees that, if any transfer of the Assigned Securities or any interest therein is proposed
to be made, as a condition precedent to any such transfer, Investor may be required to deliver to ACAH an opinion of counsel satisfactory
to ACAH that registration is not required with respect to the Assigned Securities to be transferred. Absent registration or another available
exemption from registration, Investor agrees it will not transfer the Assigned Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.5 <u>Sophisticated Investor</u>. Investor is sophisticated in financial matters and able to evaluate the risks and benefits of the investment
in the Assigned Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.6 <u>Risk of Loss</u>. Investor is aware that an investment in the Assigned Securities is highly speculative and subject to substantial
risks. Investor is cognizant of and understands the risks related to the acquisition of the Assigned Securities, including those restrictions
described or provided for in this Agreement, the Sponsor LLC Agreement and the Letter Agreement pertaining to transferability. Investor
is able to bear the economic risk of its investment in the Assigned Securities for an indefinite period of time and able to sustain a
complete loss of such investment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.7 <u>Independent Investigation</u>. Investor has relied upon an independent investigation of ACAH and has not relied upon any information
or representations made by any third parties or upon any oral or written representations or assurances, express or implied, from the Sponsor
or any representatives or agents of the Sponsor, other than as set forth in this Agreement. Investor is familiar with the business, operations
and financial condition of ACAH and has had an opportunity to ask questions of, and receive answers from ACAH's management concerning
ACAH and the terms and conditions of the proposed sale of the Assigned Securities and has had full access to such other information concerning
ACAH as Investor has requested. Investor confirms that all documents that it has requested have been made available and that Investor
has been supplied with all of the additional information concerning this investment which Investor has requested.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.8 <u>Organization and Authority</u>. If any entity, Investor is duly organized and existing under the laws of the jurisdiction in which
it was organized and it possesses all requisite power and authority to acquire the Assigned Securities, enter into this Agreement and
perform all the obligations required to be performed by Investor hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.9 <u>Non-U.S. Investor</u>. If Investor is not a United States person (as defined by Section 7701(a)(30) of the U.S. Internal Revenue
Code of 1986, as amended, and the regulations promulgated thereunder (collectively, the " <u>Code</u> ")), Investor hereby represents
that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe
for the Assigned Securities or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the acquisition
of the Assigned Securities, (ii) any foreign exchange restrictions applicable to such acquisition, (iii) any governmental or other consents
that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the acquisition, holding,
redemption, sale, or transfer of the Assigned Securities. Investor's subscription and payment for and continued beneficial ownership
of the Assigned Securities will not violate any applicable securities or other laws of Investor's jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.10 <u>Authority</u>. This Agreement has been validly authorized, executed and delivered by Investor and is a valid and binding agreement
enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent
conveyance, moratorium, reorganization, or similar laws relating to, or affecting generally the enforcement of, creditors' rights
and remedies or by equitable principles of general application and except as enforcement of rights to indemnity and contribution may be
limited by federal and state securities laws or principles of public policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.11 <u>No Conflicts</u>. The execution, delivery and performance of this Agreement and the consummation by Investor of the transactions
contemplated hereby do not violate, conflict with or constitute a default under (i) Investor's organizational documents, (ii) any
agreement or instrument to which Investor is a party or (iii) any law, statute, rule or regulation to which Investor is subject, or any
order, judgment or decree to which Investor is subject, in the case of clauses (ii) and (iii), that would reasonably be expected to prevent
Investor from fulfilling its obligations under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.12 <u>No Advice from Sponsor</u>. Investor has had the opportunity to review this Agreement and the transactions contemplated by this
Agreement and the form of Letter Agreement with Investor's own legal counsel and investment and tax advisors. Except for any statements
or representations of the Sponsor explicitly made in this Agreement, Investor is relying solely on such counsel and advisors and not on
any statements or representations, express or implied, of the Sponsor or any of its representatives or agents for any reason whatsoever,
including without limitation for legal, tax or investment advice, with respect to this investment, the Sponsor, ACAH, the Assigned Securities,
the transactions contemplated by this Agreement or the securities laws of any jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.13 <u>Reliance on Representations and Warranties</u>. Investor understands that the Assigned Securities are being offered and sold to
Investor in reliance on exemptions from the registration requirements under the Securities Act, and analogous provisions in the laws and
regulations of various states, and that the Sponsor is relying upon the truth and accuracy of the representations, warranties, agreements,
acknowledgments and understandings of Investor set forth in this Agreement in order to determine the applicability of such provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.14 <u>No General Solicitation</u>. Investor is not subscribing for Assigned Securities as a result of or subsequent to any general solicitation
or general advertising, including but not limited to any advertisement, article, notice or other communication published in any newspaper,
magazine, or similar media or broadcast over television or radio or any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.15 <u>Brokers</u>. No broker, finder or intermediary has been paid or is entitled to a fee or commission from or by Investor in connection
with the acquisition of the Assigned Securities nor is Investor entitled to or will accept any such fee or commission.

4. <u>Representations and Warranties of Sponsor</u>. The Sponsor represents and warrants to, and agrees with, the Investor that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.1 <u>Power and Authority</u>. The Sponsor is a limited liability company duly formed and validly existing and in good standing as a
limited liability company under the laws of Delaware and possesses all requisite limited liability company power and authority to enter
into this Agreement and to perform all of the obligations required to be performed by the Sponsor hereunder, including the assignment,
sale and transfer the Assigned Securities and the assignment of the Economic Interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.2 <u>Authority</u>. All corporate action on the part of the Sponsor and its officers, directors and members necessary for the authorization,
execution and delivery of this Agreement and the performance of all obligations of the Sponsor required pursuant hereto has been taken.
This Agreement has been duly executed and delivered by the Sponsor and (assuming due authorization, execution and delivery by Investor)
constitutes the Sponsor's legal, valid and binding obligation, enforceable against the Sponsor in accordance with its terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization, or similar
laws relating to, or affecting generally the enforcement of, creditors' rights and remedies or by equitable principles of general
application and except as enforcement of rights to indemnity and contribution may be limited by federal and state securities laws or principles

Agreement.

5. <u>Trust Account</u>. Until the earlier of (a) the consummation of ACAH's initial business combination; (b) the liquidation
of the Trust Account; and (c) 30 months from consummation of ACAH's initial public offering or such later time as the stockholders

maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule

(including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic

10. <u>Survival; Severability</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.1 <u>Survival</u>. The representations, warranties, covenants and agreements of the parties hereto shall survive the closing of the

11. <u>Headings</u> *.* The titles and subtitles used in this Agreement are used for convenience only and are not to be considered
in construing or interpreting this Agreement.

12. <u>Disclosure; Waiver</u>. As soon as practicable, but in no event later than one business day, after execution
of this Agreement, the Company will file (to the extent that it has not already filed) a Current Report on Form 8-K under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), disclosing, to the extent not previously
publicly disclosed, (a) all material terms of the transactions contemplated hereby and (b) any other material non-public information that
the Sponsor, the Company, or any person acting on behalf of either has provided to Investor at any time prior to the filing of the Form
8-K . The parties to this Agreement shall cooperate with one another to assure that such disclosure is accurate. ACAH agrees that
the name of the investor shall not be included in any public disclosures related to this Agreement unless required by applicable law,
regulation or stock exchange rule. Investor (i) acknowledges that the Sponsor may possess or have access to material non-public information
which has not been communicated to the Investor; (ii) hereby waives any and all claims, whether at law, in equity or otherwise, that he,
she, or it may now have or may hereafter acquire, whether presently known or unknown, against the Sponsor or any of ACAH's officers,
directors, employees, agents, affiliates, subsidiaries, successors or assigns relating to any failure to disclose any non-public information
in connection with the transaction contemplated by this Agreement, including any potential business combination involving ACAH, including
without limitation, any claims arising under Rule 10-b under the Exchange Act; and (iii) is aware that the Sponsor is relying on the truth
of the representations set forth in Section 3 of this Agreement and the foregoing acknowledgement and waiver in this Section 12, in connection
with the transactions contemplated by this Agreement.

13. <u>Independent Nature of Rights and Obligations</u>. Nothing contained herein, and no action taken by any party pursuant hereto, shall
be deemed to constitute Investor and the Sponsor as, and the Sponsor acknowledges that Investor and the Sponsor do not so constitute,
a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Investor and the Sponsor are
in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any
matters, and the Sponsor acknowledges that Investor and the Sponsor are not acting in concert or as a group, and the Sponsor shall not
assert any such claim, with respect to such obligations or the transactions contemplated by this Agreement.

14. <u>Most Favored Nation</u>. In the event the Sponsor or ACAH enters one or more other non-redemption agreements before or after the
execution of this Agreement in connection with the Meeting, the Sponsor and ACAH represent that the terms of such other agreements are
not materially more favorable to such other investors thereunder than the terms of this Agreement are in respect of the Investor. For
the avoidance of doubt, the Sponsor and the Company acknowledge and agree that a ratio of Investor Shares to Assigned Securities in any
such Other Agreement that is more favorable to such Other Investor than such ratio in this Agreement is to Investor would be materially
more favorable to such Other Investor. In the event that another investor is afforded any such more favorable terms than the Investor,
the Sponsor shall promptly inform the Investor of such more favorable terms in writing, and the Investors shall have the right to elect
to have such more favorable terms included herein, in which case the parties hereto shall promptly amend this Agreement to effect the
same.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.

______, 20_

Reference is made to that certain Non-Redemption Agreement and Assignment of Economic Interest, dated as of _____, 2023 (the "<u>Agreement</u>"), by and among ______ ("<u>Investor</u>"), Atlantic Coastal Acquisition Corp. (the "<u>Company</u>") and Atlantic Coastal Acquisition Management LLC (the "<u>Sponsor</u>"), pursuant to which Investor acquired securities of the Company from the Sponsor. Capitalized terms used and not otherwise defined herein shall have the meanings given to such terms in the Agreement.

By executing this joinder, Investor hereby agrees, as of the date first set forth above, that Investor (i) shall become a party to that certain Letter Agreement, dated March 3, 2021, by and among the Company, the Sponsor and the Company's officers and directors (as it exists on the date of the Agreement, the "<u>Letter Agreement</u>"), solely with respect to Section 8 of the Letter Agreement, and shall be bound by, and shall be subject to the restrictions set forth under, the terms and provisions of such section of the Letter Agreement as an Insider (as defined therein) solely with respect to its Assigned Securities; and (ii) shall become a party to that certain Registration Rights Agreement, dated March 3, 2021, by and among the Company and the Sponsor (as it exists on the date of the Agreement, the "<u>Registration Rights Agreement</u>"), and shall be bound by the terms and provisions of the Registration Rights Agreement as a Holder (as defined therein) and entitled to the rights of a Holder under the Registration Rights Agreement and the Assigned Securities (together with any other equity security of the Company issued or issuable with respect to any such Assigned Securities by way of a share dividend or share subdivision or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization) shall be "Registrable Securities" thereunder.

For the purposes of clarity, it is expressly understood and agreed that each provision contained herein, in the Letter Agreement (to the extent applicable to Investor) and the Registration Rights Agreement is between the Company and Investor, solely, and not between and among Investor and the other stockholders of the Company signatory thereto.
