The undersigned, Geokinetics Holdings USA, Inc. (the “Borrower”), refers to the Senior Secured Debtor-in-Possession Credit Agreement dated as of March [__], 2013 (as amended, amended and restated, supplemented, replaced and/or otherwise modified from time to time, the “Credit Agreement”; the terms defined therein being used herein as therein defined), among the Borrower, Geokinetics Inc., Cantor Fitzgerald Securities, as Administrative Agent and Collateral Agent for the Lenders, and each Lender party thereto, and hereby gives you irrevocable notice that, pursuant to Section 2.05(a) of the Credit Agreement, on [date]⁵, the undersigned intends to prepay the Loans, in the amount of $____________. The undersigned confirms that it has obtained the consent of the Backstop DIP Lenders to effect this prepayment.

FOR VALUE RECEIVED, the undersigned, Geokinetics Holdings USA, Inc., a Delaware corporation (the “Borrower”), HEREBY PROMISES TO PAY _________________________ or its registered assigns (the “Lender”) for its account or, if one has been designated, for the account of its Applicable Lending Office (as defined in the Credit Agreement referred to below; terms defined therein, unless otherwise defined herein, being used herein as therein defined) on the Maturity Date the aggregate principal amount of the Loans owing to the Lender by the Borrower pursuant to the Senior Secured Debtor-in-Possession Credit Agreement dated as of March [__], 2013 (as amended, amended and restated, supplemented, replaced and/or otherwise modified from time to time, the “Credit Agreement”) among the Borrower, Geokinetics Inc., a Delaware corporation, Cantor Fitzgerald Securities, as Administrative Agent and Collateral Agent for the Lenders, and each Lender from time to time party thereto.

The Borrower promises to pay interest on the unpaid principal amount of each Loan from the date of such Loan, as the case may be, until such principal amount is paid in full, at such interest rates, and payable at such times, as are specified in the Credit Agreement.

Both principal and interest are payable in lawful money of the United States of America to Cantor Fitzgerald Securities, as Administrative Agent, at such office and in the manner specified in the Credit Agreement. Each Loan owing to the Lender by the Borrower, and all payments made on account of principal thereof, shall be recorded by the Lender and, prior to any transfer hereof, endorsed on the grid attached hereto, which is part of this Note; provided, however, that the failure of the Lender to make any such recordation or endorsement shall not affect the Obligations of the Borrower under this Note and the other Loan Documents.

This promissory note is one of the Notes referred to in, and is entitled to the benefits of, the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of Loans by the Lender to or for the benefit of the Borrower from time to time in an aggregate amount not to exceed at any time outstanding the U.S. dollar amount first above mentioned (subject to certain terms and other limitations set forth in the Credit Agreement), the indebtedness of the Borrower resulting from each such Loan being evidenced by this Note, and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events and also for prepayments on account of principal hereof prior to the maturity hereof upon the terms and conditions therein specified. The Obligations of the Borrower under this Note and the other Loan Documents, and the Obligations of the other Loan Parties under the Loan Documents, are secured by the Collateral as provided in the Loan Documents.

The Borrower, for itself, its successors and assigns, hereby waives diligence, presentment, protest and demand and notice of protest, demand, dishonor and non-payment of this Note.

This Note may not be transferred or assigned by the Lender to any Person EXCEPT IN COMPLIANCE WITH THE TERMS OF THE CREDIT AGREEMENT. This Note may not at any time be endorsed to, or to the order of, bearer.
