AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements contained herein, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

ARTICLE I

AGREEMENTS OF THE INVESTOR

1.1            The Investor covenants and agrees to reverse and revoke any prior redemption elections made with respect to the Shares and that, prior to the Termination Date, neither it nor any of its affiliates shall (a) directly or indirectly Transfer (other than to any fund or account managed by the same investment manager as the Investor) any of the Shares, or any voting or economic interest therein, as of and following the date hereof through the earlier of (i) the Closing of the Business Combination and (ii) the termination of the Business Combination Agreement in accordance with its terms, or (b) exercise any redemption rights under the Second Amended and Restated Certificate of Incorporation of SPAC, as may be further amended or restated from time to time (the “Charter”), in connection with (i) the Business Combination or (ii) any meeting of SPAC at which SPAC shareholders may ordinarily exercise redemption rights pursuant to the Charter, with respect to the Shares (collectively, the “Redemption Rights”). For purposes hereof, “Transfer” shall mean, with respect to the Shares, the transfer, sale, offer, exchange, assignment, pledge (other than pursuant to standardized pledge arrangements with the Investor’s prime brokers) or other disposition. For the avoidance of doubt, nothing in this Agreement shall limit or restrict Investor’s right to conduct any transfer, sale, offer, exchange, assignment, pledge (other than pursuant to standardized pledge arrangements with the Investor’s prime brokers) or other disposition of any SPAC Shares on or after the Closing Date.

1.2            In furtherance of the foregoing: (a) through the Termination Date, the Investor hereby irrevocably waives, on behalf of itself and its affiliates, the Redemption Rights and irrevocably constitutes and appoints SPAC and its respective designees, with full power of substitution, as its (and its affiliates) true and lawful agent and attorney-in-fact, with full power and authority in its name, place and stead, to revoke any redemption election made in contravention of Section 1.1 above with respect to any Shares and to cause SPAC’s transfer agent to fail to redeem such Shares in connection with the Business Combination, and (b) in the event of a breach of Section 1.1 with respect to any Shares (the “Transferred/Redeemed Shares”), the Investor unconditionally and irrevocably agrees to, or to cause one or more of its affiliates to, subscribe for and purchase from SPAC (or from its permitted assignee(s) or designee(s)) a number of ordinary shares of SPAC equal to the number of such Transferred/Redeemed Shares, for a per share purchase price equal to the amount to be received by public shareholders of SPAC exercising their Redemption Rights in connection with the Business Combination.

1.3            The Investor hereby agrees that neither the Investor nor any person or entity acting on behalf of the Investor or pursuant to any understanding with the Investor has engaged nor, from the date of this Agreement until the Closing Date, will engage in any hedging transactions or Short Sales with respect to securities of SPAC. For purposes of this Section 1.3, “Short Sales” shall include, without limitation, (a) all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, (b) all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage or other similar financing arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and (c) sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.

1.4            The obligations of the Investor set forth in Sections 1.1, 1.2 and 1.3 of this Agreement shall be subject to the satisfaction, or valid waiver by the Investor, of the conditions that:

(a)            all representations and warranties of the Sponsor and SPAC contained in this Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality, which representations and warranties shall be true and correct in all respects) at and as of the Closing Date (except for representations and warranties made as of a specific date, which shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality, which representations and warranties shall be true and correct in all respects) as of such date); and

(b)            the Sponsor and SPAC shall have performed, satisfied, and complied in all material respects with all covenants, agreements and conditions required by this Agreement to be performed, satisfied, or complied with by it at or prior to the Closing.

1.5            For the avoidance of doubt, the Investors agree and acknowledge that any currently existing or new subsidiary directly or indirectly owned or controlled by Pubco (i) may obtain project financing for projects owned or developed by that subsidiary and, as part of such project financing, (ii) may encumber, mortgage or grant a security interest in its shares and/or assets. The term “project financing” shall refer to long-term debt or equity financing for a project to be repaid from the cash flow generated by that project.

ARTICLE II

AGREEMENTS OF THE SPONSOR AND SPAC

2.1            In consideration of the Investor’s performance of its obligations described herein and upon satisfaction (or, if applicable, waiver) of the conditions set forth in Section 2.2 of this Agreement, the Sponsor and the SPAC will cause to be delivered at the Closing 1,589,000 Founder Shares and 145,000 Private Warrants (the “Investor Company Securities”) to be listed and admitted to trading on the Nasdaq Stock Market LLC. The Investor Company Securities shall be issued to the Investor and the managed accounts or fund entities for which the Investor exercises investment discretion, as designated in writing to SPAC. The Investor Company Securities will contain the same legends and be restricted in the same manner as applicable to Sponsor on the date hereof. The Investor will not sell, pledge, gift or otherwise transfer, or cause to be sold, pledged, gifted or otherwise transferred, any of the Investor Company Securities until after the Closing has occurred.

2.2            Upon the Closing of the Business Combination, if there is not an effective registration statement covering all the Founder Shares and the SPAC Shares underlying the Private Warrants, then the Sponsor shall cause Pubco be filed, within 30 days of the Closing of the Business Combination, a registration statement, and Pubco will use its reasonable best efforts to cause such registration statement to be promptly declared effective under the Securities Act, in compliance with such registration request.

3

2.3            The obligations of the Sponsor and SPAC set forth in Section 2.1 of this Agreement shall be subject to the satisfaction, or valid waiver by the Sponsor and SPAC, of the conditions that:

(a)            all representations and warranties of the Investor contained in this Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality, which representations and warranties shall be true and correct in all respects) at and as of the Closing Date (except for representations and warranties made as of a specific date, which shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality, which representations and warranties shall be true and correct in all respects) as of such date); and

(b)            the Investor shall have performed, satisfied, and complied in all material respects with all covenants, agreements and conditions required by this Agreement to be performed, satisfied, or complied with by it at or prior to the Closing.

MISCELLANEOUS

4.1            Termination.

SPAC shall notify the Investor of the termination of the Business Combination Agreement promptly after the termination thereof. Upon the occurrence of any Termination Event, except as set forth in the proviso to the first sentence of this Section 4.1, this Agreement shall be void and of no further effect.

4.2            Trust Account Waiver. Reference is made to the definitive proxy statement filed with the U.S. Securities and Exchange Commission (“SEC”) on November 13, 2023 (the “Proxy Statement”). The Investor has reviewed the Proxy Statement and acknowledges that SPAC has established the trust account described in the Proxy Statement (the “Trust Account”) for the benefit of the public shareholders (the “Public Shareholders”) and the underwriter (“Underwriter”) of SPAC’s initial public offering (“IPO”) and that, except for certain exceptions described in the Proxy Statement, SPAC may disburse monies from the trust account only: (i) to the Public Shareholders in the event of the redemption of their shares or the liquidation of SPAC; (ii) to SPAC and the Underwriters after the consummation of a business combination, as described in the Proxy Statement (a “Business Combination”), (iii) to the Public Shareholders in the event SPAC does not consummate a Business Combination prior to May 28, 2024 (assuming the exercise of all available extensions), or (iv) with respect to any interest earned on the amounts held in the Trust Account, amounts necessary to pay any taxes and up to $100,000 in dissolution expenses. The Investor hereby agrees that it does not have any right, title, interest or claim of any kind in or to any monies in the Trust Account (a “Claim”) and hereby waives any Claim it may have now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with SPAC or makes any Claim against the Trust Account for any reason whatsoever. The Investor agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by SPAC and its representatives to induce SPAC to enter into this Agreement, and the Investor further intends and understands such waiver to be valid, binding and enforceable against the Investor and each of its representatives under applicable law.

7

To the extent the Investor or any of its affiliates commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to SPAC or its representatives, which proceeding seeks, in whole or in part, monetary relief against SPAC or its representatives, the Investor hereby acknowledges and agrees that its and its representatives and affiliates’ sole remedy shall, except (i) as may be set forth in any definitive agreement or (ii) in connection with any rights or claims of the Investor or any of its related parties as a shareholder of SPAC to the extent related to or arising from any shares of the SPAC, including for the avoidance of doubt, any right to redeem its shares, be against funds held outside of the Trust Account and that such Claim shall not permit the Investor, or its representatives or affiliates or shareholders (or any person claiming on any of their behalves or in lieu of any of them) to have any claim against the Trust Account or any amounts contained therein.

4.3            Disclosure; Waiver. As of the date hereof, to the Sponsor and SPAC’s knowledge, Investor is not in possession of any material non-public information received from the Sponsor, Alternus, SPAC or any of their respective officers, directors or employees. SPAC shall, by 9:00 a.m., New York City time, within four (4) Business Days following the date of this Agreement, file with the Commission a Current Report on Form 8-K disclosing all material terms of the transactions contemplated hereby. The parties to this Agreement shall cooperate with one another to assure that such disclosure is accurate. Each of the Sponsor and SPAC agrees that the name of Investor shall not be included in any public disclosures related to this Agreement unless required by applicable law, regulation or stock exchange rule. Investor acknowledges that the Sponsor and SPAC may possess or have access to material non-public information which has not been communicated to Investor. The Sponsor and SPAC shall not deliver, and shall cause Alternus and their respective officers, directors or employees not to deliver, to Investor any material non-public information relating to the Sponsor, Alternus or SPAC without Investor’s prior written consent. The Sponsor, Alternus and SPAC shall, by 9:00 a.m., New York City time, on the date following the Closing of the Business Combination, file with the Commission a Current Report on Form 8-K disclosing any material non-public information delivered to Investor after the date of this Agreement.

4.4            Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Agreement must be brought exclusively in the United States District Court for the Southern District of New York, the Supreme Court of the State of New York and the federal courts of the United States of America located in the State of New York (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 4.10 of this Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above.

8

4.5            Waiver of Jury Trial. EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

4.6            Assignment. Neither this Agreement nor any rights that may accrue to the Investor hereunder may be transferred or assigned. Neither this Agreement nor any rights that may accrue to the Sponsor or SPAC hereunder may be transferred or assigned. Notwithstanding the foregoing, the Investor may assign its rights and obligations under this Agreement to one or more of its affiliates or equity holders (including other investment funds or accounts managed or advised by the Investor or investment manager who acts on behalf of the Investor or an affiliate thereof) or, with SPAC’s prior written consent, to another person, provided that (i) such assignee(s) agrees in writing to be bound by the terms hereof, and upon such assignment by the Investor, the assignee(s) shall become the Investor hereunder and have the rights and obligations and be deemed to make the representations and warranties of the Investor provided for herein to the extent of such assignment and (ii) no such assignment shall relieve the Investor of its obligations hereunder if any such assignee fails to perform such obligations.

4.7            Specific Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that SPAC shall be entitled to specifically enforce the Investor’s obligations and the provisions of the Agreement, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (a) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (b) not to assert that a remedy of specific enforcement pursuant to this Section 4.7 is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (c) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate. In connection with any proceeding for which SPAC is being granted an award of money damages, the Investor agrees that such damages, to the extent payable by the Investor, shall include, without limitation, damages related to the consideration that is or was to be paid to SPAC under this Agreement and such damages are not limited to an award of out-of-pocket fees and expenses related to this Agreement.
