This Non-Redemption Agreement and Assignment of Economic Interest (this “Agreement”) is entered as of April 4, 2023 by and among Atlantic Coastal Acquisition Corp. II (“ACAB”), Atlantic Coastal Acquisition Management II LLC, a Delaware limited liability company (the “Sponsor”) and the undersigned investors (collectively, the “Investor”).

RECITALS

WHEREAS, the Sponsor currently holds ACAB Series B common stock initially purchased in a private placement prior to ACAB’s initial public offering (the “Founder Shares”);

WHEREAS, ACAB expects to hold a special meeting of stockholders (the “Meeting”) for the purpose of approving, among other things, an amendment to ACAB’s Amended and Restated Certificate of Incorporation (the “Charter”) to extend the date by which ACAB must consummate an initial business combination (the “Initial Business Combination”) by at least six additional months until October 19, 2023 (the “Extension”);

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

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 Exhibit A (the “Assigned Securities”), to be transferred to Investor in connection with ACAB’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:

Securities set forth on Exhibit A, 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) [________] Public Shares, and (ii) 9.9% of the Series A common stock outstanding after the Meeting (including those Public Shares subject to non-redemption agreements with other ACAB stockholders similar to this Agreement on or about the date of the Meeting), after giving effect to all redemptions of Series A common stock in connection with the Meeting. The Sponsor and ACAB 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.

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 January 13, 2022, by and among the Company, the Sponsor and the Company’s officers and directors (as it exists on the date hereof, the “Letter Agreement”) 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.

1.3 Adjustment to Share Amounts. 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 ACAB 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.

1.4 Merger or Reorganization, etc. If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving ACAB 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 ACAB, 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.

1.5 Forfeitures, Transfers, etc. 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 “Sponsor LLC Agreement”), prior to, or at the time of, the Initial Business Combination, the managers of the Sponsor have the authority to cause

2

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.

1.6 Delivery of Shares; Other Documents. 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 ACAB’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.

1.7 Assignment of Registration Rights. 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 January 13, 2022, by and among the Company and the Sponsor (as it exists on the date of the Agreement, the “Registration Rights Agreement”), 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 ACAB of such assignment in accordance with the Registration Rights Agreement. Investor and ACAB 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.

1.8 Joinder to Letter Agreement. 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 Exhibit B (the “Joinder”) pursuant to which Investor shall agree with ACAB 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.

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. Assignment of Economic Interest.

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 Exhibit A (the “Economic Interest”), 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 Exhibit A represented by the Founder Shares held directly by the Sponsor.

2.2 If at any time the number of outstanding Common stock of ACAB 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 Series 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 Common stock.

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.

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.

4

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. Representations and Warranties of Investor. Investor represents and warrants to, and agrees with, the Sponsor that:

3.1 No Government Recommendation or Approval. Investor understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Assigned Securities.

3.2 Accredited Investor. 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 “Securities Act”), 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.

3.3 Intent. 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.

3.4 Restrictions on Transfer; Trust Account; Redemption Rights.

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.

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 ACAB’s initial public offering were deposited (the “Trust Account”) or distributed as a result of any liquidation of the Trust Account.

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 ACAB 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.

5

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 ACAB an opinion of counsel satisfactory to ACAB 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.

3.5 Sophisticated Investor. Investor is sophisticated in financial matters and able to evaluate the risks and benefits of the investment in the Assigned Securities.

3.6 Risk of Loss. 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.

Investor has relied upon an independent investigation of ACAB 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 ACAB and has had an opportunity to ask questions of, and receive answers from ACAB’s management concerning ACAB and the terms and conditions of the proposed sale of the Assigned Securities and has had full access to such other information concerning ACAB as Investor has requested.

3.14 No General Solicitation. 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.
