OPTION AGREEMENT

This OPTION AGREEMENT (the “Agreement”), dated as of November 18, 2014, by and between NAVIOS MARITIME ACQUISITION CORPORATION (the “Seller”), a corporation organized under the laws of the Republic of the Marshall Islands, and NAVIOS MARITIME HOLDINGS INC. (the “Buyer”), a corporation organized under the laws of the Republic of the Marshall Islands.

WITNESSETH

WHEREAS, Navios Maritime Midstream GP LLC, a limited liability company organized under the laws of the Republic of the Marshall Islands (the “General Partner”), is the general partner of Navios Maritime Midstream Partners L.P., a limited partnership organized under the laws of the Republic of the Marshall Islands and recently formed subsidiary of the Seller (the “Partnership”);

WHEREAS, the Seller owns 100% of the outstanding membership interests in the General Partner (the “Membership Interests”), 381,334 General Partner Units, representing the entire 2.0% general partner interest in the Partnership (the “General Partner Units”) and all of the incentive distribution rights in the Partnership representing the right to receive an increasing percentage of quarterly distributions when certain conditions are met (the “Incentive Distribution Rights”); and

WHEREAS, the Seller desires to grant to the Buyer, and the Buyer desires to accept from the Seller, the option to purchase any or all of the Membership Interests, General Partner Units or Incentive Distribution Rights, subject to the limitations set forth below.

NOW, THEREFORE, the parties hereto agree as follows:

1. Option. The Seller hereby grants the Buyer the option (the “Option”) to acquire from the Buyer any or all of the Membership Interests, General Partner Units or Incentive Distribution Rights (the “Option Interest”) upon the following terms and subject to the following conditions (for purposes of this Agreement and for the avoidance of doubt, the “Option Interest” shall include (i) any additional Membership Interests, General Partner Units or Incentive Distributions Rights that may be issued or distributed by way of a stock dividend, stock split or distributed, or acquired by way of any rights offering or similar offering made in respect of such Option Interest or in connection with a combination of shares, recapitalization, acquisition, merger, consolidation or other reorganization, or as may be acquired by the Seller in the future):

(a) The Seller grants the Option to the Buyer on the date of execution of this Agreement. The Option shall expire on November 18, 2024 (the “Option Period”).

(b) The Buyer may exercise the Option as to all or any part of the Option Interest at any time and from time to time during the Option Period by written notice (an “Option Exercise Notice”) delivered to the Seller (at the Seller’s address identified in the Limited Partnership Agreement), provided that any such exercise shall relate to not less than twenty-five percent of the Option Interest.

(c) The purchase price for the acquisition of all or any part of the Option Interest shall be an amount equal to the Fair Market Value for the Option Interest (the “Option Purchase Price”). For purposes of this Agreement, “Fair Market Value” means the value that would be paid by a willing buyer to an unaffiliated willing seller in an arm’s length transaction not involving distress or necessity of either party. The Buyer shall pay the Option

Purchase Price for any portion of the Option Interest being acquired on the applicable Option Closing Date by wire transfer of same day funds to any account designated by the Seller.

(d) The “Option Closing Date” with respect to the acquisition of any portion of the Option Interest shall be the business day set forth by the Buyer in the applicable Option Exercise Notice; provided, however, that no such closing shall take place later than November 18, 2024. On each Option Closing Date, the Parties shall execute a purchase agreement in relation to the relevant portion of the Option Interest with the same terms as those set forth in this Agreement.

(e) If the Buyer fails to provide any written notice of its intention to exercise the Option under this Section 1 within the Option Period or if, after delivering an Option Exercise Notice, the Buyer fails to close on that portion of the Option Interest to be acquired thereunder by the corresponding Option Closing Date, the Buyer will automatically forfeit its right to exercise the Option with respect to that portion of the Option Interest and any other portion of the Option Interest which has not yet been acquired by the Buyer.
