establish the price applicable to that Service or Material, if lower than the pricing under the Pricing Book Terms, including any agreed upon discounts. If Contractor does not exercise its right to perform the Work at a price equal to ninety-nine

considered in breach of this Agreement in the event that Company is prohibited from solely approving Contractor for any Work by reason of any of Company’s obligations existing under any of the agreements set forth on Schedule 2.7.

such agreements for Contractor to perform such Work.

SCOPE OF WORK 
 2.1 Work. 
 (a) At any time and from time to time during the
Term, when Company desires Work to be performed in the Contract Area, a Company Representative shall give Contractor a request for such Work. The request may be oral or in the form of a quote, work request, purchase order, letter, signed field
ticket, memorandum, fax or other document that is accepted, orally or in writing, by Company and Contractor (collectively, a “Work Order”). The Work Order will include (i) a description of the Services or Material to be
provided, (ii) specifications, drawings and requirements, as applicable, (iii) a schedule for delivery, installation and completion of the Work, as applicable, (iv) consideration to be paid to Contractor and basis for payment and
(v) and other terms and conditions specific to the subject Services or Material. The Contractor may accept such Work Orders subject to the availability of its equipment and personnel. 

(b) If and when there is an agreement between Company and Contractor regarding the specific terms of the Work Order,
Contractor shall thereafter commence the performance of the Work in accordance with the terms and conditions of the Work Order and this Agreement. Commencement of the Work by Contractor shall be deemed to be an acceptance of the terms and conditions
of the Work Order and this Agreement. With respect to a Work Order for the purchase of Materials, (i) if such Work Order is construed as an offer, it expressly limits acceptance by Contractor to the terms of the Work Order and this Agreement,
and (ii) if such Work Order is construed as an acceptance of an offer, it is expressly conditioned on Contractor’s agreement to any additional or different terms contained herein. Unless otherwise agreed in a Work Order, Contractor shall
provide all Services, including, without limitation, all maintenance, supervision and engineering support, and all Materials, including, without limitation, all supplies, parts, tools, instruments, vehicles and facilities needed to perform the Work
safely and in a good and workmanlike manner and in full compliance with all applicable laws, regulations and standards. 

 2.2 Change Order. From time to time a Company Representative may, with
Contractor’s prior acknowledgment, clarify, modify, expand or reduce the Work pursuant to a written change order (a “Change Order”). Contractor shall comply with all directions in such Change Orders, provided that,
without Contractor’s prior written consent, Contractor shall not be required to perform Work that is beyond the general scope of Work described in the Work Order. Contractor reserves the right to charge Company for additional labor and expense
in connection with a Change Order. 
 2.3 Most Favored Terms. 

(a) Upon the request of Company, Contractor shall provide to Company with such information as Company may reasonably
request in order to confirm the Most Favored Terms; provided, that (i) Contractor may require that Company enter into a confidentiality agreement, in a form reasonably satisfactory to Contractor, as a condition to providing such information;
(ii) Contractor shall not be required to provide any information to the extent Contractor is restricted from doing so by any applicable law or any confidentiality obligations to Third Parties; and (iii) the information provided shall be
limited to only that information that is necessary to determine Most Favored Terms. 
 (b) Company agrees that
Contractor’s pricing under the Most Favored Terms (i) is based on the scope of Work and (ii) will be based on pricing that takes into account the kind, amount and location of work provided by Contractor to its Third Party customers.
At any time during the Term, with respect to Work provided by Contractor to Company on the Most Favored Terms, if Contractor enters into any agreement with any Third Party customer that provides for benefits or terms more favorable than those
contained in this Agreement for similar services, under similar contract terms and using similar equipment in a similar location, this Agreement shall be deemed to be modified to provide Company with such more favorable benefits and terms.

 2.4 Preferred Contractor. For any Work that the Company subjects to a competitive bid, Company shall give Contractor
the right to bid for any such Work, and for any Work not subjected to a competitive bid, Contractor shall be given the first right to quote for any such Work. At any time, Company shall be free to acquire competitive bids from competing service
providers, including Contractor, for Work. In the absence of a formal tender, all bidding standards shall be comparable to Contractor’s customary bidding standards, with such bidding process clearly identifying the health, safety, security, and
environmental services to be provided, equipment and manpower standards and terms. If a Third Party bid for Work, which satisfied the bidding standards, is lower than the bid offered by Contractor for such Work, Contractor shall have the right to
perform such Work at a discounted price equal to ninety-nine percent (99%) of the price of such lower bid, and such discounted price shall presumptively establish the price applicable to that Service or Material, if lower than the pricing under
the Pricing Book Terms, including any agreed upon discounts. During Phase II (as defined below) for any particular Service or Material, if Contractor does not exercise its right to perform the Work at a price equal to ninety-nine percent
(99%) of the lowest bid for economic reasons and not for reasons of equipment or personnel availability, then Company shall be free to utilize Third Party service providers for such Work and for the duration of performance under the applicable
Work Order. Contractor shall have the right to audit Company’s books and records, subject to prior notice by Contractor to Company and conducted during Company’s normal working hours, to confirm compliance with this
Section 2.4. 

 2.5 Notwithstanding anything in this Agreement to the contrary, Company shall not be
considered in breach of this Agreement in the event that Company is prohibited from solely approving Contractor for any Work by reason of any of Company’s obligations existing under any of the agreements set forth on Schedule 2.5.
Provided, however, notwithstanding the provisions of such agreements, if Contractor would otherwise have the right to perform the Work hereunder, Company agrees that it will seek approval from any applicable joint or operating committee under any
such agreements for Contractor to perform such Work. 
 SECTION 3 

TERM 
 The term of this Agreement (the “Term”) shall commence on the Effective Date and shall continue in full force and effect for a primary term lasting until the date that is the fifth
anniversary of the Effective Date and shall be automatically renewed for successive renewal terms of one (1) year each, unless terminated by either Party by written notice at least sixty (60) days prior to the end of the primary term or
any successive renewal term. The Term shall be broken up into two phases as described below: 
 3.1 Phase I (Status Quo
Period). 
 (a) For the four (4) month period beginning on the Effective Date (“Phase
I”), Contractor agrees that it will provide Company with any and all Work utilizing equipment, personnel and capacity to perform Work that it has available at the time of the applicable Work Order. Contractor shall take all reasonable steps
to ensure that any equipment, personnel and capacity to perform Work that is owned by Contractor as of the Effective Date and that is available, and not committed to provide services to Third Parties at the Effective Date, remains available to
Company throughout Phase I, provided that Contractor will not be prevented from pursuing Third Party work during Phase I as provided in Section 3.1(b). 

(b) At any time during Phase I, Company shall have a right of first refusal to secure, on a Firm Basis, any Work that
Contractor proposes to provide to any other Person (other than Work being provided to Third Parties as of the Effective Date). Accordingly, Contractor shall give notice to Company of any proposal by Contractor to supply Work to a Third Party during
Phase I. Within ten (10) days following receipt of such notice, Company may elect by notice to Contractor to have Contractor provide such Work to or for the benefit of Company, on a Firm Basis. The failure by Company to make such election
within such period shall entitle Contractor to provide such Third Party with such Work. 
 3.2 Phase II (Firm Commitment
Period). 
 (a) Phase II of the Term (“Phase II”) will commence at the end of Phase I and
continue through the remainder of the Term. Throughout Phase II, Services and Material can be contracted for on a Firm Basis, at less than 100% utilization, and for such periods and upon such terms, as the Parties may mutually agree and to the
extent Contractor has such Services and Material available. 

 (b) It is contemplated that substantially all Material that is owned by
Contractor as of the Effective Date and currently based in Turkey will remain based in Turkey during Phase II; provided, that 
 (i) seismic equipment may be exported from Turkey for Work during time periods that such equipment has not been contracted for seismic shoots for Company; and 

(ii) other Material may be temporarily exported from Turkey, and if contracted by Company on a Firm Basis, Contractor will
use its reasonable best efforts to re-import the Material as quickly as reasonably possible in order to fulfill the terms of the applicable Work Order. 
 (c) During Phase II, in the event that Company contracts on a Firm Basis for some, but not all, of Contractor’s capacity of a particular Service or Material, Contractor is free to contract with Third
Parties regarding the remaining capacity; provided that the Parties shall work in good faith to minimize conflicts between such Third Party contracts and the Work to be performed hereunder. 

(d) During Phase II, for all Work to be performed for Company, Contractor shall offer pricing equal to the Most Favored
Terms. 
 SECTION 4 
 INDEPENDENT CONTRACTOR RELATIONSHIP 
 It is the understanding and
intention of the Parties hereto that no relationship of master and servant or principal and agent shall exist between Company, on the one hand, and the Contractor or any of its employees, agents or representatives, on the other hand. In the
performance of any Work by Contractor for Company, Contractor shall be deemed to be an independent contractor. Nothing contained in this Agreement will be construed to be inconsistent with such independent contractor relationship.

disruptions to the operations of each Party.

visually inspect all materials furnished by Company prior to use and to notify Company of any apparent defects in the materials. Contractors shall not be liable for any loss or damage resulting from latent or patent defects in materials furnished by

Section 5.1, except as otherwise provided in this Agreement, Contractor shall, at Contractor’s own cost and at Company’s election, (i) repair or re-perform at a mutually agreed upon rate, but in any event, not less than
50% of original cost, such defective Services as are brought to Contractor’s attention in writing, and/or (ii) repair or replace such defective Materials with the type originally furnished, provided Contractor is notified thereof in
writing; provided, that Company shall notify Contractor of the defect or other circumstance requiring re-performance before Contractor’s personnel has left the applicable Work Site. In the event that Contractor fails to make a good faith
attempt to remedy a breach of Section 5.1, the Company may at its option terminate this Agreement. Prior to terminating this Agreement for a breach of Section 5.1, Company will provide Contractor with a ten (10) day

supplies furnished by Contractor Group or any of Contractor’s Subcontractors hereunder or pursuant to any Work Order and agrees to allow no lien or charge to be fixed upon property of Company or the party for whom Company is performing Work due

to resolve the dispute. If the dispute still cannot be resolved by such management level representatives within five (5) business days of receiving same, then the dispute together with all particulars, will be forwarded to an executive officer

that they deem just and equitable, including but not limited to injunctive relief, whether interim and/or final, and any provisional measures ordered by the arbitrators may be specifically enforced by any court of competent jurisdiction. Each Party
