Upon conversion of all of the outstanding Loans pursuant to this Section 8.01, the Lender shall surrender the Note, duly endorsed, at the principal offices of the Borrower or any transfer agent of the Borrower. At its expense, the Borrower will, as soon as practicable thereafter, issue and deliver to the Lender, at such principal office, a certificate or certificates for the number of shares to which the Lender is entitled upon such conversion, together with any other securities and property to which the Lender is entitled upon such conversion under the terms of this Agreement, including a check payable to the Lender for any cash amounts payable as described herein.

FORM OF PROMISSORY NOTE

$50,000,000

Dated: _________, 201__

FOR VALUE RECEIVED, the undersigned, DryShips Inc., a Marshall Islands corporation (the "Borrower") HEREBY PROMISES TO PAY to the order of Sifnos Shareholders Inc., a Marshall Islands corporation (the "Lender"), the principal sum of FIFTY MILLION U.S. DOLLARS ($50,000,000) or, if less, the principal amount that is outstanding on the Maturity Date; provided, however, that such payment shall be in the amount necessary to repay in full the unpaid principal amount hereof together with interest on the principal amount hereof from time to time outstanding from the date hereof until such principal amount is paid in full. Both principal and interest are payable to the Lender in U.S. Dollars.

This Promissory Note is one of the Notes issued pursuant to the Secured Revolving Facility Agreement, dated October 21, 2015, between the Borrower and the Lender (the "Agreement") and is subject to and entitled to the benefits of the Facility Agreement. Capitalized terms that are not defined in this Promissory Note have the meanings given to them in the Agreement.

The principal amount of indebtedness evidenced hereby shall be payable in the amounts and on the dates specified in the Facility Agreement, the terms of which are incorporated herein by reference. Interest thereon shall be paid until such principal amount is paid in full at such interest rates and at such times, and pursuant to such calculations, as are specified in the Agreement.

During the continuance of any one or more Events of Default as specified in the Agreement, all amounts then remaining unpaid on this Promissory Note shall become, or may be declared to be, immediately due and payable, all as provided in the Agreement.

Upon the failure of the Borrower to pay the Lender when due and payable any and all amounts payable by the Borrower to the Lender under the provisions of this Promissory Note, the entire unpaid amount of this Promissory Note then outstanding shall become immediately due and payable, without presentment, demand, protest or other notice of any kind, all of which are expressly waived, and without any action on the part of the Lender. If this Promissory Note is referred to an attorney for collection or enforcement, the Borrower shall pay all costs and expenses of collection or enforcement, including attorneys' fees.

Any legal action or proceeding with respect to this Promissory Note may be brought by the Lender in the courts of the State of New York or the courts of the United States of America for the Southern District of New York. By execution and delivery of this Promissory Note, the Borrower consents, for itself and in respect of its property, to the jurisdiction of those courts. The Borrower irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the

bringing of any action or proceeding in such jurisdiction in respect of this Promissory Note or other document related thereto. The Borrower hereby waives personal service of any summons, complaint or other process, which may be made by any other means permitted by the law of New York.

No failure on the part of the Lender to exercise, and no delay in exercising, any right, power or privilege hereunder shall operate as a waiver thereof or a consent thereto; nor shall a single or partial exercise of any such right, power or privilege preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

THE BORROWER HEREBY WAIVES ANY RIGHT WHICH IT MAY HAVE TO REQUEST A TRIAL BY JURY IN ANY ACTION RELATED TO THIS PROMISSORY NOTE.

THIS PROMISSORY NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF.
