3.Amendment and Restatement of Section 3.1.  Section 3.1 (including all of Subsections 3.1.1 through 3.1.6) of the Contract is hereby fully amended and restated as follows:
“3.1    Purchase Price.

4.Additional Deposit.  Upon the full execution of this Amendment by the parties hereto, Purchaser shall deposit with the Escrow Agent the additional sum of Four Million and 00/100 Dollars ($4,000,000.00) (the “Supplemental Deposit”), which Supplemental Deposit shall become part of the Deposit under the Contract.

7.Waiver of Ancillary Document Contingency.  Purchaser hereby waives the Ancillary Document Contingency set forth in Paragraph 12 of the Second Amendment to Purchase and Sale Agreement.
8.Food Trucks.

9.Amendment and Restatement of Subsections 10.1.2 to 10.1.8.  Subsections 10.1.2 through 10.1.8 of the Contract are hereby fully amended and restated as follows:
“10.1.2        Development Sites.

10.Amendment and Restatement of Certain Provisions Related to Potential Ballfield Purchase.  Paragraph 13 (Ballfield Purchase) of the Second Amendment to Purchase and Sale Agreement, beginning with the phrase “The Ballfield Costs shall not include more than the . . .” at the bottom of page 13 of the Second Amendment to Purchase and Sale Agreement, is hereby amended and restated to read as follows:
“The Ballfield Costs shall not include more than the actual costs incurred, or that reasonably should have been incurred, by the Ballfield Site Owner to construct the Ballfield, in accordance with the County’s requirements, on a single level of concrete surface above the existing number of parking spaces currently lying on the Ballfield Site, and to make the area lying under the Ballfield usable for parking with at least the existing number of parking spaces currently lying on the Ballfield Site (the “Existing Parking Count”) in a reasonable commercial manner (e.g. with adequate levels, lighting, ingress and egress lanes, landscaping, etc.); which means that any costs incurred by the Ballfield Site Owner to construct additional parking spaces beyond the Existing Parking Count below the Ballfield and/or to construct improvements on the Ballfield Site not necessary to convert the existing surface parking lot into a parking structure with a Ballfield on the top surface of such parking structure shall be at the sole cost and expense of the Ballfield Site Owner and shall not be part of the Ballfield Costs.  The “Default Conditions” are if both of the following events occur:  (a) Purchaser fails to timely consummate the purchase of the Property (other than Block F) by the date for Closing set forth in Section 10.1.2, as it may be extended as provided in the Contract, and (b) such event is a Purchaser default pursuant to Section 12.3 that caused Seller to terminate the Contract and retain the Deposit.  The “Meridian Fund Entities” shall mean each of the following entities, on a joint and several basis: (1) Meridian Realty Partners Co-Invest I, L.P., (2) Meridian Realty Partners TE I, L.P., (3) Meridian Realty Partners H I, L.P., (4) Meridian Realty Partners NUS I, L.P. and (5) Meridian Realty Partners Series I, L.L.C., Series A and B.  This Paragraph 13 shall cease to have any force and effect upon the completion of the next Closing under the Contract.”
11.No Obligation to Provide Seller Demolition Credit.  Notwithstanding anything to the contrary contained in the Contract, including, without limitation, the provisions of Paragraph 10 of the Second Amendment to Purchase and Sale Agreement, Seller shall have no obligation to provide the Seller Demolition Credit to Purchaser.
12.Reaffirmation.  Except as modified by this Amendment, the Contract remains in full force and effect and the undersigned parties do hereby ratify and confirm the Contract, as modified by this Amendment.  It is mutually covenanted, stipulated and agreed between the parties hereto that the Contract, as modified by this Amendment, constitutes the entire agreement between the parties with respect to the subject matter of the Contract and supersedes any and all prior agreements or undertakings, if any, whether written or oral.  To the extent any provision in this Amendment conflicts with any other term or provision of the Contract, this Amendment shall control.
13.Counterparts.  This Amendment may be signed in one or more counterparts, all such separately signed counterparts shall be deemed to be a single instrument hereof, and facsimile or imaged reproductions of signatures hereto shall be deemed as effective as originals.

subsidiaries identified in Schedule A hereto that will be acquired by the Company together with any additional
subsidiaries that may acquire vessels or enter into newbuilding contracts in the future (the
“Subsidiaries”), and PYXIS MARITIME CORP. (“Maritime”).

          Whereas
the Subsidiaries are the registered owners of the ships (the “Vessels”) described in Schedule A annexed
hereto, it being understood that such Schedule will be deemed amended for any ships or ships under construction that will be acquired
by the Subsidiaries in the future; and

          Whereas
the Company desires Maritime to provide, subject to the terms and conditions set forth herein, certain administrative and management
services in respect of the Vessels and/or to the Company, and Maritime is willing and able to provide such services ; and 

           Whereas
the Company and Maritime entered into a Head Management Agreement on March 23, 2015 and the parties wish to amend that agreement
and restate it in its entirety as set forth herein. 

          Now
therefore, in consideration of the foregoing and for other good and valuable consideration, the parties hereto agree as follows:

1. APPOINTMENT

    (a)    Maritime is hereby appointed
by the Company as ship manager and Maritime hereby agrees to act as ship manager of the Vessels and to the Company.

    (b)    Maritime undertakes to use
its best efforts to provide the following services (the “Ship Management Services”) to the Vessels and for
any Vessels to be acquired in the future, namely: commercial, sale and purchase, provisions, insurance, bunkering and lubricants,
operations and maintenance, dry-docking and newbuilding construction supervision, and unless otherwise agreed by the parties,
to oversee:

	 	 	 
	 	(1)	the crewing and technical management for all the Vessels, which crewing and technical management will be conducted by
    International Tanker Management Ltd. (“ITM”) and/or such other satisfactory person to be agreed between
    the parties; and
	 	 	 
	 	(2)	the chartering for the Vessels set forth on Schedule A-l, which chartering will be conducted by North Sea Tankers
    BV (“NST”) or such other satisfactory person to be agreed between the parties.

Notwithstanding the foregoing, the parties acknowledge that
in performing the Ship Management Services, Maritime may use and/or subcontract the Ship Management Services to other agents, consultants,
brokers, etc., some of which may be affiliates of Maritime.

    (c)   
Maritime shall render advice and provide executive, financial, accounting and other administrative services (the “Administrative
Services”) to the Company from time to time, including, but not limited to, the services of a chief executive officer,
a chief financial officer, a senior vice president for corporate development and general counsel (who will serve as secretary
of the Company), a chief operations officer, one or more internal auditors and a secretary and such other matters as may be mutually
agreed between Maritime and the Company. The executive services shall only be performed by the following persons: President and
Chief Executive officer by Valentios Valentis, Senior Vice President for Corporate Development and General Counsel by Antonios
Backos, and Chief Operating Officer by Konstantinos Lytras. The candidates for Chief Financial Officer, the internal
auditor(s) and the secretary performing these services or replacements for any of the individuals performing the services must

by the parties.

 

    	 

    	 

    

    (d)    Maritime undertakes to use
its best efforts to provide the following additional services to the Company as part of the Administrative Services:

conditions of the Shipman to the extent the two are inconsistent or in conflict. The parties acknowledge that each Subsidiary
has entered or will also enter into separate management agreements with ITM, NST and to the extent required or customary, with
any other agents, consultants, brokers used by Maritime to provide the Ship Management Services.

    (f)     In the exercise of its duties

of Maritime in the performance of Maritime’s Services and shall reimburse Maritime for any fees and/or commissions charged
to Maritime by other agents, consultants, brokers, etc.

    not dismissed or stayed within 90 days of its filing, or if the Company or Maritime shall admit in writing its insolvency
    or its inability to pay its debts as they mature, or if an order is made for the appointment of a liquidator, manager, receiver

(i)           The Company hereby confirms to and agrees with Maritime
with respect to any and all matters arising out of or in connection with its engagement as a ship manager hereunder, that Maritime
shall be entitled to receive the benefits of all indemnification provisions contained in the bylaws of the Company to the fullest
extent permitted by applicable law at the time of the assertion of any liability against Maritime. Without limiting the generality
of the foregoing, the Company hereby covenants and agrees that Maritime shall be entitled to receive any and all indemnification
to which Maritime would have been entitled had it or they acted as an officer or director of the Company, including, without limitation,
such indemnification benefits as may hereafter be extended or otherwise made available by the Company to its executive officers.

 

Maritime shall cooperate fully with the Company in the prosecution
or defense, as the case may be, of any and all actions, governmental inquiries or other legal proceedings in which Maritime’s
assistance may be requested by the Company. Such cooperation shall include, among other things, making documents in Maritime’s
custody or control available to the Company or its counsel, making itself available for interviews by the Company or its counsel,
and making itself available to appear as a witness, at deposition, trial or otherwise. Any and all reasonable and necessary vouchered
out-of-pocket expenses incurred by Maritime in fulfilling its obligations under this paragraph 11 (i) shall be reimbursed by the
Company.

 

The provisions of this Section 11 (i) shall survive the termination
or expiration of this Agreement.
