(1)	E.A.D.M. Schiffahrt GmbH & Co. KG, having its registered office at Herdentorswallstraße 93, 28195 Bremen, Germany (the "Sellers"); and

(2)	KNIGHT OCEAN NAVIGATION CO., having its registered office at 80 Broad Street, Monrovia, Liberia (the "Buyers");

WHEREAS:

(A)	The Sellers are the registered owners of the E.R. BAYERN currently registered under the Luxemburg flag and under the German Registry with IMO number 9507893 (the "Vessel"); and

(B)

Through a nomination of the Buyers as buyers by Seanergy Maritime Holdings Corp. of Majuro, The Marshall Islands ("Seanergy"), the Sellers and Buyers have entered into a "SALEFORM 2012" Memorandum of Agreement dated 26 September 2016 (together with Addendum no.1 dated 6 October 2016 and any and all addenda thereto referred to as the "Agreement") for the sale of the Vessel by the Sellers to the Buyers.

(C)

Pursuant to the terms of Clause 9 of the Agreement the Sellers have undertaken to indemnify the Buyers against all consequences of any claim made or threatened against the Vessel which was incurred prior to the time of delivery or arose out of or with respect to events occurred prior to the time of delivery to the Buyers, up to a maximum total amount of United States Dollars Three Hundred Thousand (USD 300,000.00) (the "Security Amount"), and it has been further agreed that the Security Amount will be deposited by the Sellers in a joint escrow account (the "Second Escrow Account") in Hamburg with the Deposit Holder (as defined in the Agreement).

(D)

The Sellers have requested from the Buyers to amend this provision in a way that, instead of the Sellers, E.R. Capital Holding GmbH & Cie KG, having its registered office at Hohe Bleichen 12, 20354 Hamburg, Germany (the "Sellers' Parent Entity") pays the Security Amount into the Second Escrow Account.

(E)	Subject to the terms and conditions of this Addendum No. 2, the Buyers and the Sellers' Parent Entity are willing to agree and consent to Sellers' request described under recital (D) above.

IT IS NOW THEREFORE MUTUALLY AGREED BETWEEN THE PARTIES HEREOF AS FOLLOWS:

AMENDMENT OF CLAUSE 9, CLAUSE 20 AND CLAUSE 22 OF THE AGREEMENT & PLACEMENT OF THE SECURITY AMOUNT BY THE SELLERS' PARENT ENTITY

Terms defined in the Agreement shall have the same meaning when herein used, unless the context otherwise requires.

Therefore, Clause 9 of the Agreement shall be deemed replaced as follows:

"The Sellers only warrant that the Vessel, at the time of delivery, is free from all registered encumbrances and registered mortgages.

If however, within four (4) months from the time of delivery of the Vessel to the Buyers, any claim is made or threatened against the Vessel which was incurred prior to the time of delivery or arose out of or with respect to events occurred prior to the time of delivery, the Sellers hereby undertake to indemnify the Buyers against all consequences of such claims up to a maximum total amount of USD 300,000.00 (in words: United States Dollars three hundred thousand). The Sellers shall, as a condition for the payment of the Purchase Price by the Buyers, procure that an amount of USD 300,000.00 (in words: United States Dollars three hundred thousand) (hereinafter the "Security Amount") is deposited not later than one (1) Banking Day prior to delivery by E.R. Capital Holding GmbH & Cie KG, having its registered office at Hohe Bleichen 12, 20354 Hamburg, Germany (the "Sellers' Parent Entity") in an escrow account with the Deposit Holder (the "Security Amount Escrow Account"), the costs of such account to be borne by the Sellers' Parent Entity, as security for the Buyers in respect of such claims. The Deposit Holder shall hold the Security Amount according to an escrow agreement (the "Security Amount Escrow Agreement") to be made between Seanergy Maritime Holdings Corp. of Majuro/The Marshall Islands, the Sellers' Parent Entity and the Deposit Holder.

50% of (the balance of) the Security Amount on the Security Amount Escrow Account shall be released to the Sellers' Parent Entity's bank account (to be advised by the

Sellers' Parent Entity) two (2) months after the delivery of the Vessel, and the remaining 50 % of the Security Amount shall be released to the Sellers' Parent Entity's bank account (to be advised by the Sellers' Parent Entity) four (4) months after the delivery of the Vessel in accordance with the terms and conditions of the Security Amount Escrow Agreement. The Buyers' recourse in respect of claims under this Clause 9 of this Agreement shall be limited to the available balance of the Security Amount in the Security Amount Escrow Account. The Buyers shall have no further claim against the Sellers in this regard, howsoever caused, whether negligently or otherwise, with respect to claims made or threatened against the Vessel."

The Security Amount Escrow Agreement shall be entered into substantially on the terms set out in Exhibit "A" hereto.

The Parties agree and accept that the Security Amount Escrow Agreement will be concluded between Seanergy, the Sellers' Parent Entity and the Deposit Holder. As the Security Amount is meant to secure certain claims pursuant to Clause 9 of the Agreement in the contractual relationship between the Sellers and the Buyers, the Sellers shall procure that the Sellers' Parent Entity will perform and exercise all rights and obligations pursuant to the Security Amount Escrow Agreement in accordance with Sellers' instructions, and the Buyers shall procure that Seanergy will perform and exercise all rights and obligations pursuant to the Security Amount Escrow Agreement in accordance with Buyers' instructions. For the avoidance of doubt, in particular but without limitation, Seanergy may notify any claims of the Buyers for indemnification under the Security Amount Escrow Agreement and neither the Sellers nor the Sellers' Parent Entity shall be entitled to reject such notification of a claim based on the fact that this is being raised by Seanergy instead of the Buyers.

It is further agreed that the Security Amount paid or which will be paid by the Sellers' Parent Entity shall be deemed in fulfilment of the Sellers' obligation to lodge the Security Amount and shall constitute security for the correct fulfilment by the Sellers of their obligations under Clause 9 of the Agreement. Release of the Security Amount or parts thereof to Seanergy shall be deemed in fulfilment of the Sellers' obligations to indemnify the Buyers under Clause 9 of the Agreement.

Consequently to the above amendments to the Agreement, Clause 20 o) of the Agreement shall be deemed deleted.

Consequently to the above amendments to the Agreement, the following change of Clause 22 of the Agreement (Closing Procedure) is agreed:

At the end of Clause 22 a), the following new and additional sentence is added:

"… Not later than one (1) Banking Day prior to the closing, the Sellers' Parent Entity shall remit the Security Amount to the Security Amount Escrow Account and ensure settlement of the costs relating to the opening and maintaining of the Security Amount Escrow Account."

At the end of Clause 22 b), the following new and additional sentence is added:

"… Also before or at the beginning of the closing the Deposit Holder will confirm to the Parties that the Security Amount has been received in the Security Amount Escrow Account and that this will be held and released in accordance with the terms and conditions of the Security Amount Escrow Agreement."

Clause 22 j) shall be deemed deleted.

Except as provided hereinabove, the terms and conditions of the Agreement shall remain unchanged and in full force and effect.

IN WITNESS WHEREOF the parties hereto have caused this Addendum No. 2 to be executed by their duly authorised representatives on the date written above.

ii.
