1. Introduction.

SERCEL and certain of its Affiliates design, manufacture and market fully-configured seismic data acquisition systems (the “SERCEL Systems”). At the present time, SERCEL and certain of its Affiliates manufacture equipment including the Products. For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged for all purposes, MITCHAM and SERCEL agree to the terms set forth herein.

2. Exclusive Authorized Third Party Lessor.

(a) MITCHAM hereby represents to SERCEL that MITCHAM has the necessary skills, experience, personnel, facilities and equipment to effectively perform its responsibilities as described in the Agreement. In reliance upon that representation, SERCEL hereby appoints MITCHAM as the exclusive authorized lessor of the Products throughout the Territory and as the non-exclusive authorized lessor throughout the CIS; except that MITCHAM shall not offer financing leases or leases equal to or greater than one year duration except with SERCEL’s prior written consent. This Agreement does not allow MITCHAM to act as distributor, agent, commercial representative or reseller of brand-new Products.

The exclusivity herein granted is expressly subject to the compliance by MITCHAM with its yearly minimum purchase requirement under article 4 herein and with other yearly minimum purchase requirements subscribed by MITCHAM under the Equipment purchase agreement applicable to other products.

(b) During the term of this Agreement, SERCEL and/or any Affiliate shall remain free to perform, directly or indirectly, with any third party any lease purchase or operating lease with a term greater than or equal to six (6) months or any financial lease. The Parties acknowledge that the purpose of this Agreement is the purchase of Products by MITCHAM.

(c) For the avoidance of doubt, MITCHAM will not rent the DSU3-428 system for use in mainland China to any seismic contractor that is owned or controlled by Chinese nationals without SERCEL’s prior written consent.

(d) During the term of the Agreement, in the event that a third party makes inquiry of SERCEL as to the possibility of pure operating lease in respect of any of the Products anywhere in the Territory for a term less than six (6) months, then and upon each inquiry, SERCEL shall contact MITCHAM (by phone, email or letter) and explain in reasonable detail the identity of the third party, and MITCHAM shall promptly contact such third party and negotiate the terms of the proposed lease. Mitcham shall have discretion to accept or reject any third party referred by SERCEL for leasing as a result of (i) possessing an insufficient amount of the Products for lease to such third party (provided, however, the continued failure of MITCHAM to maintain a sufficient amount of products to satisfy demand could be evidence that MITCHAM is not actively promoting the leasing of Products, as required hereunder unless caused by the failure of SERCEL to deliver Products to MITCHAM), (ii) reasonably apparent credit risk or any other reasonable business-related factor, or (iii) inability to reach agreement on the terms of such lease. Notwithstanding the previous sentence, MITCHAM shall use commercially reasonable best efforts to service every third party referred by SERCEL for leasing. MITCHAM shall be deemed to have rejected such a third party as a result of inability to agree on the terms within fifteen (15) business days of

Pg. 2

such third party’s first contact by MITCHAM with regard to such proposed lease. SERCEL may then respond to this one time business opportunity in any means it sees fit. If SERCEL leases to such third party, then SERCEL shall have the right to continue to lease to such third party after the term of the initial lease; provided, however, that if (x) the lease between such a third party and SERCEL shall terminate, (y) the leased Product is returned to SERCEL, and/or (z) such third party shall later make an inquiry concerning leasing of the Products, SERCEL shall again follow the procedure set forth in this Sub-Section (d); and provided further that when such lease ends, SERCEL will offer to sell any Products leased thereunder to MITCHAM, on mutually agreed terms. The purchase of these products will not count toward the minimum purchase commitment made by MITCHAM to SERCEL in this agreement.

(e) SERCEL will have the right to operate a pool of equipment dedicated to “lease with option to purchase” agreements based on minimum initial rental periods of six (6) months or greater. Equipment from this pool may subsequently be re-rented to clients for periods less than six (6) months.

(f) In no event shall either SERCEL or MITCHAM have any right to require that the other party charge any specific price or follow any pricing guidelines or establish or require any other specific or general term with regard to the leasing of any of the Products, or the provision of any other good or service by either of them. Notwithstanding the foregoing, MITCHAM shall use its commercially reasonable best efforts to have a reasonable quantity of the Products available for lease at prices which MITCHAM believes reflects the supply of and demand for the Products.

3. Purchase of Products from SERCEL.

(a) Subject to the other provisions of this Agreement, MITCHAM agrees that it will purchase from SERCEL and SERCEL agrees that it will sell to MITCHAM, all of the Products necessary to meet MITCHAM’s obligations under each lease as provided herein. The terms and conditions of purchases by MITCHAM of the Products hereunder shall be governed by SERCEL’s general terms and conditions, a copy of which is attached hereto as Schedule 2(a); provided, however, that in the event of any conflict between the terms of such terms hereof, the terms of the Agreement shall prevail. SERCEL may update Schedule 2(a) from time to time after written notice to MITCHAM.

(b) MITCHAM shall receive the discounts set forth on Schedule 2(b) with regard to the Products ordered by MITCHAM in each order, subject to adjustment agreed to by the parties pursuant to paragraph 3(c) herein.

(c) The Parties acknowledge that SERCEL’s prices for the products are based on discounts offered by SERCEL based on volume.

(d) Delivery is Ex-Works SERCEL plant(s). Packing charges will be quoted to MITCHAM and the purchase order received from MITCHAM will reflect the full value of the quotation including packing charges. MITCHAM may instruct SERCEL at their discretion to include freight and insurance in the proposal. This will be quoted at SERCEL’s cost plus a handling fee of ten percent (10%).

Pg. 3

(e) SERCEL reserves the right to increases prices of product and repair services up to five percent (5%) per year. This only includes products and repair services that involve SERCEL manufactured products. Out sourced services and products will be increased at a proportionate level to increases imposed on SERCEL.

4. Minimum Purchase Requirements for DSU3-428.

(a) Subject to the terms hereof, MITCHAM will issue a purchase order for 5000 DSU3-428 within two weeks of signing this agreement. This purchase order will be called “Master PO”. Subsequently, MITCHAM will issue purchase orders which reference the relevant Master PO to draw against the 5000 DSU3-428. These purchase orders will be called “Supply PO’s” and will apply toward the minimum purchase requirements in section 4(b) herein. Supply PO’s may be issued by any MITCHAM Affiliate and will be directed to the appropriate SERCEL Affiliate as directed by SERCEL. In the event that MITCHAM does not purchase Products from SERCEL via Supply PO’s under this Agreement in an amount that satisfies the Minimum Purchase Requirements (set forth in section 4(b), at SERCEL’s option but subject to Section 4(c) below, SERCEL may terminate this Agreement on 30 days written notice; and upon such termination MITCHAM shall not be obligated to purchase any Products other than the Products that it has ordered prior to the effective date of such termination or SERCEL may terminate the exclusivity granted to MITCHAM without terminating the whole Agreement.

(b) For purposes hereof, the term “Minimum Purchase Requirement” shall mean Products purchased and delivered to MITCHAM via Supply PO’s from SERCEL as follows:

From October 1, 2012 to December 31, 2012: purchase of 2,500 DSU3-428. From January 1, 2013 to December 31, 2013: purchase of 2,500 DSU3-428

(c) Notwithstanding anything herein to the contrary, in the event that a Minimum Purchase Requirement is not satisfied by MITCHAM in any period ending before December 31, 2012, this Agreement may not be terminated by SERCEL due to such failure if MITCHAM meets the Minimum Purchase Requirement for the subsequent period but SERCEL may, at its sole option, terminate the exclusivity granted.

(d) For purposes of determining whether MITCHAM has satisfied the Minimum Purchase Requirement, Products purchased by MITCHAM shall include Products ordered by MITCHAM via Supply PO’s regardless of when such Products are delivered so long as such Products are ordered before 75 days of the end of a period and paid for in accordance with the terms and conditions set forth in Schedule 2(a). If MITCHAM orders within the specified period and SERCEL is not able to deliver due to manufacturing delivery issues, there will be no penalty against MITCHAM and such orders will be applied to satisfy the Minimum Purchase Requirement. In the event MITCHAM purchases more than the Minimum Purchase Requirement in any given period, such excess shall be applied in meeting the Minimum Purchase Requirement for any subsequent period.

5. Third Party Replacement Parts. Any use of replacement parts that have not been qualified by SERCEL will give SERCEL the right, in any case, to cancel any warranty remaining on the equipment for which such unqualified parts are used.

Pg. 4

6. Resale of Purchased Equipment by MITCHAM. Without SERCEL’s prior written consent, MITCHAM hereby agrees that it will not sell any of the Products purchased under this Agreement until a period of three (3) years from the date it received the relevant Product. Without limiting the foregoing, MITCHAM may approach SERCEL with a lease to purchase or sales opportunity for equipment purchased hereunder, and SERCEL may then grant MITCHAM the right to pursue that opportunity. Notwithstanding anything to the contrary contained in this Agreement, MITCHAM is not, in any case, entitled to sell within or outside mainland China any of the Products purchased under this Agreement to any seismic contractor owned or controlled by Chinese nationals.

7. Provision of Certain Goods and Services by SERCEL. SERCEL hereby agrees that MITCHAM shall have the right to send a reasonable number of its employees and representatives of its customers who lease the Products from MITCHAM to such technical, training, operations and maintenance classes as SERCEL provides to SERCEL’s customers who lease or purchase the Products from SERCEL, at SERCEL standard rates. SERCEL will provide MITCHAM (4) four free training courses per year to be used for any of the SERCEL training courses. This does not include the cost of travel, lodging, food or incidental expenses. SERCEL hereby agrees to send to MITCHAM such quantities of all manuals and selling information, marketing brochures and literature regarding the Products (other than proprietary information) as SERCEL develops and as MITCHAM shall reasonably request in connection with its leasing activities, at no charge to MITCHAM. SERCEL’s current training price schedule can be changed any anytime as long as MITCHAM is so notified 30 days in advance.

8. Warranty and Service.

(a) Warranty terms of the Sercel general terms and conditions of sale will apply to the Products purchased by MITCHAM under this Agreement.

(b) In no event shall MITCHAM have any authority whatsoever, express or implied, to make warranties other than those provided for herein without prior written permission from the SERCEL.

9. Maintenance and Repair of the Products.

(a) MITCHAM and SERCEL acknowledge that third party lessees of the Products from MITCHAM may return the leased Products directly to SERCEL after the termination of such third party’s leases. In such event, SERCEL shall perform its standard maintenance check of such Products and inform MITCHAM of any necessary repairs.

(b) The maintenance checks and the repairs performed by SERCEL on the Products received from the lessees shall be invoiced by SERCEL to MITCHAM at the SERCEL standard price. With respect to the repair undertaken by SERCEL, MITCHAM will be entitled to a discount on the repair pricing listed herein on attached Schedule 3. MITCHAM shall also pay the reasonable and ordinary freight and storage charges incurred by SERCEL with respect to such Products.

(c) Following such maintenance check and needed repairs, SERCEL shall ship such Products to MITCHAM at MITCHAM’s expense to a location designated by MITCHAM.

Pg. 5

10. Right to Use Name. MITCHAM shall have the right during the Term of this Agreement to (i) identify itself as the third party lessor of the Products, (ii) use all SERCEL trademarks and tradenames related to the Products that MITCHAM leases to third parties in advertisements and promotional materials; provided, however, that MITCHAM shall obtain the prior written approval of SERCEL to any such advertisements and promotional materials. No rights to manufacture are granted by this Agreement and such SERCEL trademarks and tradenames related to the Products are and shall remain the sole and exclusive property of SERCEL and MITCHAM shall have no rights therein other than as specifically set forth in this Agreement.

11. Relationship of the Parties. Neither MITCHAM nor SERCEL shall have any liability for leases or sales of any of the Products by the other. This Agreement shall not be construed as creating an agency, partnership or joint venture between MITCHAM and SERCEL. Neither MITCHAM nor SERCEL (or any of their employees or representatives) shall be construed as an agent, consultant or employee of the other for any purpose. MITCHAM shall not have the authority to bind SERCEL in any respect, it being intended that MITCHAM shall act as an independent contractor and not as an agent, with the understanding that SERCEL shall not be responsible for any obligations and/or liabilities incurred by MITCHAM in connection with its business activities.

12. Term of Agreement. Unless sooner terminated in accordance with the provisions hereof, this Agreement shall be effective from the Effective Date through December 31, 2013 (the “Term”). This Agreement may only be renewed through written agreement of both Parties.

13. No Effect on Right to Sell.

(a) This Agreement shall not be construed to have any effect on SERCEL’s rights to sell (as opposed to lease) its products and services to any party, except that SERCEL shall not knowingly sell any of the Products to any party that will lease the Products in the Territory.

(b) This Agreement shall not be construed to have any effect on MITCHAM’s rights to sell any other products or services to any party, except as otherwise provided for in this Agreement.

14. Indemnity. SERCEL and MITCHAM hereby agree to the following indemnification obligations:

(a) MITCHAM shall defend, indemnify and hold harmless SERCEL, Affiliates, its agents, employees and/or officers (the “SERCEL Indemnitees”) from and against any and all third party’s claims including MITCHAM’s customers, costs (including attorney’s fees) and expenses arising out of any injury, damage of any kind whatsoever howsoever caused whether in contract, tort (negligence included) or breach of duty including contractual or statutory duty by SERCEL or otherwise.

(b) Liabilities between the Parties.

MITCHAM shall be responsible for, indemnify, defend and hold the SERCEL Indemnitees harmless against any and all claims in respect of injury to or sickness, disease or death of any person employed by or engaged on behalf of MITCHAM or its customers or in respect of loss of or damage to physical property (including, but not limited to, plant and equipment, materials, goods, premises and facilities,) owned, supplied or borrowed by MITCHAM or its customers arising out of or in connection with the Agreement from any cause whatsoever including but not limited to the negligence or breach of duty (statutory, contractual or otherwise) of MITCHAM.

Pg. 6

SERCEL shall be responsible for, indemnify, defend and hold MITCHAM, its directors, officers, employees and Affiliates (hereinafter the “MITCHAM Indemnitees”) harmless against any and all claims in respect of injury to or sickness, disease or death of any person employed by or engaged on behalf of SERCEL or in respect of loss of or damage to physical property (including, but not limited to, plant and equipment, materials, goods, premises and facilities) owned, supplied or borrowed by SERCEL arising out of or in connection with the Agreement from any cause whatsoever including but not limited to the negligence or breach of duty (statutory, contractual or otherwise) of SERCEL.

(c) The amount of SERCEL’s liability to MITCHAM shall in no case exceed the amount of the purchase order to which such liability is related.

(d) It is expressly acknowledged by MITCHAM that all liabilities and indemnification in relation thereto between SERCEL and MITCHAM and MITCHAM’s customers, when leasing, renting or selling SERCEL equipment to MITCHAM’s customers, will be exclusively governed by SERCEL’s general conditions of sale as mentioned in Schedule 2(a) of the Agreement.

(e) Patent infringement. The parties acknowledge that if any MITCHAM customer issues a claim against MITCHAM or SERCEL on the basis that the Products are infringing a third party valid and enforceable patent, SERCEL agrees to do its best efforts to protect its patents. Without limiting the foregoing, if a final injunction is, or SERCEL believes, in its sole discretion, is likely to be entered, prohibiting the use of Products by MITCHAM’s customers, SERCEL will, at its sole option and expense, either: (a) procure for MITCHAM or its clients the right to use the relevant Products herein, or (b) replace the infringing Products with non-infringing, functionally equivalent products, or (c) suitably modify the Products so that they are not infringing; or, (d) in the event (a), (b) and (c) are not commercially reasonable, refund to MITCHAM the infringing Products at a price which is the purchase price less depreciation based on five (5) years straight-lined depreciation. Except as specified above, SERCEL will not be liable for any costs or expenses incurred without its prior written authorization. Notwithstanding the foregoing, SERCEL assumes no liability for infringement claims arising from (i) combination of the Products with other products not provided by SERCEL, (ii) any modifications to the Products unless such modification was made by SERCEL or, (iii) any part or component supplied by third party. The liability that SERCEL may incur with respect to any infringement claim is expressly limited to 100% of the amount MITCHAM paid as purchase price of the Products. MITCHAM acknowledges that Sercel is subject to an injunction regarding the sale, lease or use of the DSU3-428 within the territory of the United States of America (USA). MITCHAM will therefore not lease or sell the DSU3-428 in the USA and will so notify its customers. The above patent indemnification will not apply to any claim relating to the use of the DSU3-428 within the USA by MITCHAM or MITCHAM’s customers and Sercel shall not indemnify and shall not hold harmless the “MITCHAM Indemnitees “ or MITCHAM’s customers against any and all liability, loss, damages, fines, penalties, costs and expenses (including, without limitation, court costs and reasonable attorney’s fees) incurred by any of the Mitcham Indemnitees in relation to the DSU3-428. It is hereby however acknowledged that the injunction does not, however, apply to the DSU3-428 products sold to Mitcham, 3,500 DSU3 products sold to CGGVeritas, and 16,000 DSU3 products sold to Global Geophysical Services by Sercel Inc prior to the final

Pg. 7

judgment and injunction entered by the United States District Court for the Eastern District of Texas relating to patent infringement (ION vs. Sercel, Inc). The injunction and final judgment, which was entered by the Court on February 16, 2011, prohibits Sercel and parties acting in concert with Sercel from making, using, offering to sell, selling, renting or importing in the United States (which includes territorial waters of the United States) Sercel’s 408UL, 428XL and SeaRay digital sensor units products until the date of expiration of the relevant patent.The aforementioned sales were the subject of the damages awarded in the Final Judgment. As a result, these DSU3-428 products can be used, sold, leased or otherwise distributed in the USA.

(f) Either party seeking indemnification hereunder shall notify the other party in writing of any legal action commenced against SERCEL Indemnitees or the MITCHAM Indemnitees, as the case may be, as soon as practicable. The indemnity obligations of MITCHAM and SERCEL shall survive the expiration or termination of the Agreement.

(g) In no event will SERCEL be liable to MITCHAM, whether in contract or tort including negligence, under this Agreement as amended for special, incidental, indirect or consequential damages, nor any other losses or damages whatsoever resulting from loss of use, time, profits or business resulting from its performance or non–performance, or its termination of this Agreement as amended in accordance with the terms of this Agreement.
