THIS GUARANTEE is made on 10 April 2018

BETWEEN

(1)	EMPEROR HOLDING LTD., a corporation incorporated under the laws of the Republic of the Xxxxxxxx Islands, whose registered address is at Trust Company Complex, Ajeltake Road, Ajeltake Island, Majuro, Xxxxxxxx Islands MH96960 (the "Guarantor"); and

(2)	JELCO DELTA HOLDING CORP., a corporation incorporated under the laws of the Republic of the Xxxxxxxx Islands, whose registered address is at Trust Company Complex, Ajeltake Road, Ajeltake Island, Majuro, Xxxxxxxx Islands MH96960 (the "Lender", which expression includes its successors and assigns).

BACKGROUND

(A)	By a loan agreement dated 10 April 2018 (the "Loan Agreement") and made between (i) Seanergy Maritime Holdings Corp. as borrower (the "Borrower") and (i) the Lender as lender, it was agreed that the Lender would make available to the Borrower a loan facility of US$2,000,000 (the "Loan").

(B)

The Guarantor is a wholly owned subsidiary of the Borrower and commercially benefits from the Loan as the Loan provides additional liquidity to the Borrower ensuring that it can meet its current obligations while retaining liquidity available to fund the working capital and other financial requirements of the Guarantor.

(C)	It is a condition precedent to the Lender advancing the Loan to the Borrower under the Loan Agreement that the Guarantor shall execute and deliver to the Lender this Guarantee.

IT IS AGREED as follows:

"Secured Agreements" means the Loan Agreement, the Finance Documents and all other agreements made between the Borrower and the Lender from time to time; and

all amounts which have become due for payment by the Borrower under the Loan Agreement have been paid; and

(b)

no amount is owing or has accrued (without yet having become due for payment) under the Loan Agreement.

1.3	Application of construction and interpretation provisions of Loan Agreement

Clauses 1.2 and 1.3 of the Loan Agreement apply, with any necessary modifications, to this Guarantee.

GUARANTEE

2.1	Guarantee and indemnity

The Guarantor unconditionally and irrevocably:

(a)	guarantees the due payment of all amounts payable by the Borrower under or in connection with each of the Secured Agreements;

(b)	undertakes to pay to the Lender, on the Lender's demand, any such amount which is not paid by the Borrower when payable; and

(c)

fully indemnifies the Lender on its demand in respect of all claims, expenses, liabilities and losses which are made or brought against or incurred by the Lender as a result of or in connection with any obligation or liability guaranteed by the Guarantor being or becoming unenforceable, invalid, void or illegal; and the amount recoverable under this indemnity shall be equal to the amount which the Lender would otherwise have been entitled to recover.

2.3	Release of Guarantee

At the end of the Security Period and any similar period under the other Secured Agreements, the Lender will release the Guarantor from its obligations under this Guarantee and, at the request and cost of the Guarantor, return this Guarantee to the Guarantor.

3	LIABILITY AS PRINCIPAL AND INDEPENDENT DEBTOR

3.1	Principal and independent debtor

The Guarantor shall be liable under this Guarantee as a principal and independent debtor and accordingly it shall not have, as regards this Guarantee, any of the rights or defences of a surety.

3.2	Waiver of rights and defences

Without limiting the generality of Clause 3.1, the Guarantor shall neither be discharged by, nor have any claim against the Lender in respect of:

(a)	any amendment or supplement being made to any of the Secured Agreements;

(b)	any arrangement or concession (including a rescheduling or acceptance of partial payments) relating to, or affecting, any of the Secured Agreements;

(c)	any release or loss (even though negligent) of any right created by any of the Secured Agreements;

(d)	any failure (even though negligent) promptly or properly to exercise or enforce any such right; or

(e)	any other Secured Agreement now being or later becoming void, unenforceable, illegal or invalid or otherwise defective for any reason, including a neglect to register it.

EXPENSES

4.1	Costs of preservation of rights, enforcement etc.

The Guarantor shall pay to the Lender on its demand the amount of all expenses incurred by the Lender in connection with any matter arising out of this Guarantee or any security interest connected with it, including any advice, claim or proceedings relating to this Guarantee or such a security interest.

5.1	Reinstatement of obligation to pay

The Guarantor shall pay to the Lender on its demand any amount which the Lender is required, or agrees, to pay pursuant to any claim by, or settlement with, a trustee in bankruptcy of the Borrower on the ground that a Secured Agreement, or a payment by the Borrower, was invalid or on any similar ground.

6.2	Grossing-up for taxes

If the Guarantor is required by law to make a tax deduction, the amount due to the Lender shall be increased by the amount necessary to ensure that the Lender receives and retains a net amount which, after the tax deduction, is equal to the full amount that it would otherwise have received.

INTEREST

7.2	Calculation of interest

Interest under this Guarantee shall be calculated and accrue in the same way as interest under clause 3 of the Loan Agreement.
