THIS LOCK-UP AGREEMENT (this “Agreement”) is made and entered into as of [●], 2023 between (i) Heidmar Marine Inc., a company organized and existing under the laws of Marshall Islands (“Holdings”), and (ii) the undersigned (the “Holder”). Holdings and the Holder are sometimes referred to herein individually as a “Party” and, collectively, as the “Parties”. Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the Business Combination Agreement (as defined below).

WHEREAS, Home Plate Acquisition Corporation, a Delaware corporation, Holdings and Heidmar Inc., a company organized and existing under the laws of Marshall Islands (the “Company”), among others, entered into a business combination agreement, dated March [19], 2023 (the “Business Combination Agreement”), pursuant to which the parties thereto shall consummate a series of transactions, including the transfer of all of the Company Shares held by the Holder, the consideration of which will be, among other things, the issuance of a corresponding number of Holdings Common Shares determined in accordance with the Business Combination Agreement.

WHEREAS, pursuant to the Business Combination Agreement, and in view of the valuable consideration to be received by the Holder thereunder, Holdings and the Holder desire to enter into this Agreement, pursuant to which the Holdings Common Shares to be received by the Holder pursuant to the Business Combination Agreement, including any Earnout Shares but excluding any Holdings Common Shares acquired in connection with the PIPE Investment (together with any securities paid as dividends or distributions with respect to such securities or into which such securities are exchanged or converted, the “Restricted Securities”) shall become subject to limitations on disposition as set forth herein.

NOW, THEREFORE, in consideration of the premises set forth above, which are incorporated into this Agreement as if fully set forth below, and intending to be legally bound hereby, the Parties hereby agree as follows:

Subject to Section 1(b) and the other terms of this Agreement, Holder agrees that it shall not effectuate a Transfer of the Restricted Securities that are held by the Holder during the period ending on the earlier of (i) one year after the Closing Date or (ii) subsequent to the Closing Date (x) if the last reported sale price of the Holdings Common Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least one hundred fifty (150) days after the Closing Date or (y) the date on which Holdings completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of Holdings’ stockholders having the right to exchange their Holdings Common Shares for cash, securities or other property (in each case, the “Lock-Up Period”).

Notwithstanding the provisions set forth in Section 1(a), Transfers of the Restricted Securities that are held by the Holder (and that have complied with this Section 1(b)) are permitted (i) in the case of the Holder or its permitted transferees, to Holdings’ officers or directors, any Affiliates or immediate family members of any of Holdings’ officers or directors, any members of the Holder, any Affiliates of the Holder or any employees of such Affiliates, (ii) to shareholders or limited partners of the Holder, or, in the case of a Holder which is a limited liability partnership, its members, (iii) in the case of an individual, by gift to a member of the Holder’s immediate family or to a trust, the beneficiary (or beneficiaries) of which is one or more member of the Holder’s immediate family, an Affiliate of such person or to a charitable organization, (iv) in the case of an individual, by virtue of the laws of descent and distribution upon death of the individual, (v) in the case of an individual, pursuant to a qualified domestic relations order or in connection with a divorce settlement, (vi) by virtue of the laws of the Holder’s jurisdiction of incorporation or organization, the Holder’s organizational documents or the rights attaching to the equity interests in the Holder upon dissolution of the Holder, (vii) in connection with the exercise of any options, warrants or other convertible securities to purchase Holdings Common Shares (which exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on a cashless basis) to the extent that any Holdings Common Shares issued upon such exercise are Restricted Securities subject to Section 1(a) of this Agreement, (viii) to satisfy tax withholding obligations in connection with the Holder’s equity incentive plans or arrangements, (ix) in connection with any bona fide mortgage, pledge or encumbrance to a financial institution, as collateral or security in connection with any bona fide loan or debt transaction or enforcement thereunder, including foreclosure thereof, (x) by a Holder to any entity including any fund, partnership, company or investment trust to whom the Holder transfers interests in one or more of its portfolio of investments, or any successor entity following a restructuring transaction of that Holder, and (xi) in connection with a transfer pursuant to a bona fide third party tender offer, merger, consolidation, liquidation, share exchange or other similar transaction made to all holders of Holdings Common Shares involving a change of control of Holdings or which results in all of the holders of Holdings Common Shares having the right to exchange their Holdings Common Shares for cash, securities or other property subsequent to the consummation of such transaction; provided, that in each of clauses (i) through (xi), the transferee must enter into a written agreement in substantially the same form of this Agreement, agreeing to be bound by the terms of Section 1(a) of this Agreement (unless the transferee is Holdings). If dividends are declared and payable on the Holder’s Restricted Securities in Holdings Common Shares, such dividends will also be Restricted Securities subject to the terms of Section 1(a) of this Agreement.

If any Transfer is made or attempted contrary to the provisions of this Agreement, such Transfer shall be null and void ab initio, and Holdings shall refuse to recognize any such transferee of the Restricted Securities as one of its equity holders for any purpose. In order to enforce this Section 1, Holdings may impose stop-transfer instructions with respect to the Restricted Securities of the Holder (and any permitted transferees and assigns thereof) until the end of the Lock-Up Period.

During the Lock-Up Period, each certificate evidencing any Restricted Securities (if any are issued) shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any other applicable legends:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [●], 2023, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”) AND THE ISSUER’S SECURITY HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

For the avoidance of any doubt, the Holder shall retain all of its rights as a shareholder of Holdings with respect to the Restricted Securities during the Lock-Up Period, including the right to receive dividends and the right to vote any Restricted Securities.

For the purposes of this Section 1, “Transfer” shall mean the (a) sale of, offer to sell, contract or agreement to sell (including, for the avoidance of doubt, through a distribution in specie), hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the U.S. Securities and Exchange Commission promulgated thereunder with respect to, any security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement of any intention to effect any transaction specified in clause (a) or (b).

Effective Date. Section 1 of this Agreement shall become effective upon the Closing on the Closing Date.

Termination.

Interpretation. The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing or interpreting this Agreement. In this Agreement, unless the context otherwise requires: (i) any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including” (and with correlative meaning “include”) means including without limiting the generality of any description preceding or succeeding such term and shall be deemed in each case to be followed by the words “without limitation”; (iii) the words “herein,” “hereto,” and “hereby” and other words of similar import in this Agreement shall be deemed in each case to refer to this Agreement as a whole and not to any particular section or other subdivision of this Agreement; and (iv) the term “or” means “and/or”. The Parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

Notices. All notices, consents, waivers and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery (a) in person, (b) by e-mail (without receiving notice of non-receipt or other “bounce-back”), (c) by reputable, nationally recognized overnight courier service or (d) by registered or certified mail, pre-paid and return receipt requested; provided, however, that notice given pursuant to clauses (c) and (d) above shall not be effective unless a duplicate copy of such notice is also given in person or by e-mail (without receiving notice of non-receipt or other “bounce-back”); in each case to the applicable Party at the following addresses (or at such other address for a Party as shall be specified by like notice):

Amendments and Waivers. This Agreement may be amended, supplemented, modified or waived only by execution of a written instrument signed by each of the Parties.

No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction, such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

Specific Performance. The Parties 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. The Parties further agree that each party shall be entitled to seek specific performance of the terms hereof and immediate injunctive relief and other equitable relief to prevent breaches, or threatened breaches, of this Agreement, without the necessity of proving the inadequacy of money damages as a remedy and without bond or other security being required, this being in addition to any other remedy to which they are entitled at law or in equity.

Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the Parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the Parties is expressly superseded; provided, that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations of the Parties under the Business Combination Agreement or any Ancillary Document.
