GUARANTY

GUARANTY dated as of February 12, 2010 made by GEOKINETICS INC., a Delaware corporation (the “Parent”), the other Persons listed on the signature pages hereof and the Additional Guarantors (as defined in Section 8(b)) (the Parent, such Persons so listed and the Additional Guarantors being, collectively, the “Guarantors” and, individually, each a “Guarantor”) in favor of the Secured Parties (as defined in the Credit Agreement referred to below).

PRELIMINARY STATEMENT.  Geokinetics Holdings USA, Inc., a Delaware corporation (the “Company”) is party to that certain Credit Agreement dated as of February 12, 2010 (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”) with certain Lenders party thereto and Royal Bank of Canada, as Collateral Agent and as Administrative Agent for such Lenders.  Capitalized terms used but not otherwise defined herein shall have the meanings assigned in the Credit Agreement.

Each Guarantor will derive substantial direct and indirect benefits from the transactions contemplated by the Credit Agreement.  It is a condition precedent to the making of Loans by the Lenders and the issuance of Letters of Credit by the L/C Issuers under the Credit Agreement, the entry by the Hedge Banks into Secured Hedge Agreements from time to time and the arrangement of cash management arrangements by the Cash Management Banks that each Guarantor shall have executed and delivered this Guaranty.

NOW, THEREFORE, in consideration of the premises and in order to induce the Lenders to make Loans and the L/C Issuers to issue Letters of Credit under the Credit Agreement, the Hedge Banks to enter into Secured Hedge Agreements from time to time and the Cash Management Banks to enter into cash management arrangements from time to time, each Guarantor, jointly and severally with each other Guarantor, hereby agrees as follows:

Section 1.  Guaranty; Limitation of Liability.  (a)  Each Guarantor hereby absolutely, unconditionally and irrevocably guarantees the punctual payment when due, whether at scheduled maturity or on any date of a required prepayment or by acceleration, demand or otherwise, of all Obligations of each other Loan Party now or hereafter existing under or in respect of the Loan Documents (including, without limitation, any extensions, modifications, substitutions, amendments or renewals of any or all of the foregoing Obligations), whether direct or indirect, absolute or contingent, and whether for principal, interest, premiums, fees, indemnities, contract causes of action, costs, expenses or otherwise (such Obligations being the “Guaranteed Obligations”), and agrees to pay any and all expenses (including, without limitation, fees and expenses of counsel) incurred by the Administrative Agent or any other Secured Party in enforcing any rights under this Guaranty or any other Loan Document.  Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other Loan Party to any Secured Party under or in respect of the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party.

(b)   Each Guarantor, and by its acceptance of this Guaranty, the Administrative Agent and each other Secured Party, hereby confirms that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law (as hereinafter defined), the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the Obligations of each Guarantor hereunder.  To effectuate the foregoing intention, the Administrative Agent, the other Secured Parties and the Guarantors hereby

irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Subsidiary Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance.  For purposes hereof, “Bankruptcy Law” means any proceeding under Debtor Relief Laws.

(c)   Each Guarantor hereby unconditionally and irrevocably agrees that in the event any payment shall be required to be made to any Secured Party under this Guaranty or any other guaranty, such Guarantor will contribute, to the maximum extent permitted by law, such amounts to each other Guarantor and each other guarantor so as to maximize the aggregate amount paid to the Secured Parties under or in respect of the Loan Documents.

Section 2.  Guaranty Absolute.  Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Secured Party with respect thereto.  The Obligations of each Guarantor under or in respect of this Guaranty are independent of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Borrower or any other Loan Party or whether the Borrower or any other Loan Party is joined in any such action or actions.  The liability of each Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to, any or all of the following:

(a)           any lack of validity or enforceability of any Loan Document or any agreement or instrument relating thereto;

(b)           any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, or any other amendment or waiver of or any consent to departure from any Loan Document, including, without limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise;

(c)           any taking, exchange, release or non-perfection of any Collateral or any other collateral, or any taking, release or amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Guaranteed Obligations;

(d)           any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Guaranteed Obligations or any other Obligations of any Loan Party under the Loan Documents or any other assets of any Loan Party or any of its Subsidiaries;

(e)           any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries;

(f)            any failure of any Secured Party to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to such Secured Party (each Guarantor waiving any duty on the part of the Secured Parties to disclose such information);

2

(g)           the failure of any other Person to execute or deliver this Guaranty, any Guaranty Supplement (as hereinafter defined) or any other guaranty or agreement or the release or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or

(h)           any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any Secured Party that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Secured Party or any other Person upon the insolvency, bankruptcy or reorganization of the Borrower or any other Loan Party or otherwise, all as though such payment had not been made.

Section 3.  Waivers and Acknowledgments.  (a)  Each Guarantor hereby unconditionally and irrevocably waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that any Secured Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against any Loan Party or any other Person or any Collateral.

(e)           Each Guarantor hereby unconditionally and irrevocably waives any duty on the part of any Secured Party to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party or any of its Subsidiaries now or hereafter known by such Secured Party.

(f)            Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Loan Documents and that the waivers set forth in Section 2 and this Section 3 are knowingly made in contemplation of such benefits.

Section 4.  Subrogation.  Each Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower, any other Loan

Section 8.  Amendments, Guaranty Supplements, Etc.  (a)  No amendment or waiver of any provision of this Guaranty and no consent to any departure by any Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Administrative Agent and the Required Lenders, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by all of the Lenders (other than a Lender that is, at such time, a Defaulting Lender), (i) reduce or limit the obligations of any Guarantor hereunder, release any Guarantor hereunder or otherwise limit any Guarantor’s liability with respect to the Obligations owing to the Secured Parties under or in respect of the Loan Documents, (ii) postpone any date fixed for payment hereunder, (iii) change the number of Secured Parties or the percentage of (x) the Commitments, (y) the aggregate unpaid principal amount of the Loans or (z) the aggregate Available Amount of outstanding Letters of Credit that, in each case, shall be required for the Secured Parties or any of them to take any action hereunder or (iv) release all or substantially all of the Collateral in any transaction or series of related transactions.  Upon the sale of a Guarantor to the extent permitted in accordance with the terms of the Loan Documents, such Guarantor shall be automatically released from this Guaranty.

Section 12.  Indemnification.  (a)  Without limitation on any other Obligations of any Guarantor or remedies of the Secured Parties under this Guaranty, each Guarantor shall, to the fullest extent permitted by law, indemnify and hold harmless each Agent-Related Person, each Secured Party and their respective Affiliates, directors, officers, employees, counsel, agents, trustees, and attorneys-in-fact (collectively the “Indemnitees”) from and against any and all liabilities, obligations, losses, taxes, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever which may at any time be imposed on, incurred by or asserted against any such Indemnitee in any way relating to or arising out of or in connection with or resulting from this Guaranty (including, without limitation, enforcement of this Guaranty), except to the extent such liability, obligation, loss, damage, penalty, claim, demand, action, judgment, suit, cost, expense or disbursement is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct.

(c)           Without prejudice to the survival of any of the other agreements of any Guarantor under this Guaranty or any of the other Loan Documents, the agreements and obligations of each Guarantor contained in Section 1(a) (with respect to enforcement expenses), the last sentence of Section 2, Section 5 and this Section 12 shall survive the payment in full of the Guaranteed Obligations and all of the other amounts payable under this Guaranty.

(a)           Prohibited Payments, Etc.  Except during the continuance of a Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), each Guarantor may receive regularly scheduled payments from any other Loan Party on account of the Subordinated Obligations.  After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), however, unless the Administrative Agent otherwise agrees, no Guarantor shall demand, accept or take any action to collect any payment on account of the Subordinated Obligations.

(b)           Prior Payment of Guaranteed Obligations.  In any proceeding under any Bankruptcy Law relating to any other Loan Party, each Guarantor agrees that the Secured Parties shall be entitled to receive payment in full in cash of all Guaranteed Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post Petition Interest”)) before such Guarantor receives payment of any Subordinated Obligations.

(c)           Turn-Over.  After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), each Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for the Secured Parties and deliver such payments to the Administrative Agent on account of the Guaranteed Obligations (including all Post Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Guaranty.

(d)           Administrative Agent Authorization.  After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Bankruptcy Law relating to any other Loan Party), the Administrative Agent is authorized and empowered (but without any obligation to so do), in its discretion, (i) in the name of each Guarantor, to collect and enforce, and to submit claims in respect of, Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post Petition Interest), and (ii) to require each Guarantor (A) to collect and enforce, and to submit claims in respect of, Subordinated Obligations and (B) to pay any amounts received on such obligations to the Administrative Agent for application to the Guaranteed Obligations (including any and all Post Petition Interest).

Section 14.  Continuing Guaranty; Assignments under the Credit Agreement.  This Guaranty is a continuing guaranty and shall (a) remain in full force and effect until the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty, (b) be binding upon the Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Secured Parties and their successors, transferees and assigns.  Without limiting the generality of clause (c) of the immediately preceding sentence, any Secured Party may assign or otherwise transfer all or any portion of its rights and obligations under the Credit Agreement (including, without limitation, all or any portion of its Commitments, the Loans owing to it and the Note or Notes held by it) to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Secured Party herein or otherwise, in each case as and to the extent provided in Section 11.07 of the Credit Agreement.  No Guarantor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Secured Parties.

Section 15.  Execution in Counterparts.  This Guaranty and each amendment, waiver and consent with respect hereto may be executed in any number of counterparts and by different parties

7

thereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.  Delivery of an executed counterpart of a signature page to this Guaranty by facsimile or an electronic transmission of a .pdf copy thereof shall be effective as delivery of an original executed counterpart of this Guaranty.

Section 16.  Governing Law; Jurisdiction; Waiver of Jury Trial, Etc.  (a)  THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

(b)                                 ANY LEGAL ACTION OR PROCEEDING ARISING UNDER THIS GUARANTY OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE GUARANTORS, THE SECURED PARTIES, THE AGENTS OR ANY OF THEM WITH RESPECT TO THIS GUARANTY WHETHER NOW EXISTING OR HEREAFTER ARISING, MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE PARTIES HERETO CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS.  EACH GUARANTOR 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 ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO.

(c)           WAIVER OF RIGHT TO TRIAL BY JURY.  EACH GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE GUARANTORS, THE SECURED PARTIES, THE AGENTS OR ANY OF THEM WITH RESPECT TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH GUARANTOR AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY OF THE GUARANTORS, THE SECURED PARTIES OR THE AGENTS MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 16(C) WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.
