Morgan Securities Inc. and Deutsche Bank Securities Inc., as representatives of the underwriters (the “Representatives”), pursuant to which the Purchaser has agreed to cause [___] to place limit orders for up to $30,000,000 of shares of Common Stock (the “Aftermarket Shares”) for a period commencing on the later of (1) two business days after the Company files a preliminary proxy statement relating to its Business Combination (as defined in the Company’s Amended and Restated Articles of Incorporation in effect on the date hereof), and (2) 60 days after the termination of the “restricted period” in connection with the Initial Public Offering under Regulation M of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and ending on the business day immediately preceding the record date for the shareholder meeting at which such Business Combination is to be approved, or earlier in certain circumstances as described in the Letter Agreement; and

5. Investment Representations. In connection with the purchase of the Co-Investment Shares, the Purchaser represents to the Company the following:

(a) The Purchaser is familiar with the Company’s business plans and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Co-Investment Shares. The Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Co-Investment Shares involves a high degree of risk.

The Purchaser has such knowledge and expertise in financial and business

matters, knows of the high degree of risk associated with investments generally and particularly investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Co-Investment Shares, and is able to bear the economic risk of an investment in the Co-Investment Shares in the amount contemplated hereunder. The Purchaser understands that there presently is no public market for the Co-Investment Shares and none is anticipated to develop in the foreseeable future. The Purchaser can afford a complete loss of its investment in the Co-Investment Shares. The Purchaser is purchasing the Co-Investment Shares for investment for its own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act.

(b) The Purchaser understands that the Co-Investment Shares have not been registered under the Securities Act or any state securities law by reason of a specific exemption therefrom, and that the Company is relying on the truth and accuracy of, and the Purchaser’s compliance with, the representations and warranties and agreements of the Purchaser set forth herein to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Co-Investment Shares, including, but not limited to, the bona fide nature of the Purchaser’s investment intent as expressed herein.

(c) The Purchaser understands that the Co-Investment Shares must be held indefinitely unless the Co-Investment Shares are subsequently registered under the Securities Act or an exemption from such registration is available. The Purchaser understands that the certificates evidencing the Co-Investment Shares shall be imprinted with a legend that prohibits the transfer of the Co-Investment Shares unless the Co-Investment Shares are registered or such registration is not required in the opinion of counsel for the Company.

(d) The Purchaser represents that it is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated under the Securities Act.

(e) The Purchaser has all necessary power and authority to enter into this Agreement and to consummate the transactions contemplated hereby. All action necessary to be taken by the Purchaser to authorize the execution, delivery and performance of this Agreement and all other agreements and instruments delivered by the Purchaser in connection with the transactions contemplated hereby has been duly and validly taken, and this Agreement has been duly executed and delivered by the Purchaser. This Agreement constitutes the valid, binding and enforceable obligation of the Purchaser, enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or similar laws of general application now or hereafter in effect affecting the rights and remedies of creditors and by general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). The Purchaser’s obligations hereunder do not conflict with the organizational documents of the Purchaser, if applicable, or with any material contract by which the Purchaser or its property is bound, or any laws or regulations or decree, ruling or judgment of any court applicable to the Purchaser or its property.

(f) The Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) of the Securities Act.

(g) The Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Co-Investment Shares or the fairness or suitability of the investment in the Co-Investment Shares, nor have such authorities passed upon or endorsed the merits of the offering of the Co-Investment Shares.

(h) The Purchaser understands that except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register such Securities under the Securities Act or any state or foreign securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, the Purchaser represents that it is familiar with Rule 144 adopted pursuant to the Securities Act, and understands the resale limitations imposed thereby and by the Securities Act.

(i) The Purchaser understands that, except as specifically set forth in the Registration Rights Agreement by and among the Company and Navios Maritime Holdings, Inc., Angeliki Frangou, Ted C. Petrone, Julian David Brynteson, John Koilalous, Nikolaos Veraros and the Purchaser, neither the Company nor any other person is under any obligation to register such Co-Investment Shares under the Securities Act or any state or foreign securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, the Purchaser represents that it is familiar with Rule 144 adopted pursuant to the Securities Act, and understands the resale limitations imposed thereby and by the Securities Act.

(j) Without in any way limiting the representations set forth above, the Purchaser agrees not to make any disposition of the Co-Investment Shares unless and until:

(A) There is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(B) The Purchaser shall have notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition and, if reasonably requested by the Company, the Purchaser shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such Co-Investment Shares under the Securities Act.
