Inc. (“GFES”) a Delaware corporation whose address for the purposes hereof is 4023 Ambassador Caffery Pkwy, Suite 200, Lafayette, Louisiana 70503, and Alliance Consulting Group, L.L.C. a Louisiana limited liability company whose address
for the purposes hereof is 3201 General DeGaulle Drive, Suite 200, New Orleans, Louisiana 70114. Hereinafter, Alliance Consulting Group, L.L.C. and its affiliates shall be collectively referred to as “ACG”. 

Recitals 

GFES entered into a certain lease agreement with Mass Prentis Blackwell, Jr., as landlord (together with any successor landlord,
“Landlord”), the owner of the fee simple interest in the Wet Facilities (as defined below), dated as of October 1, 2011 and more particularly described on Schedule 1 attached hereto and incorporated herein by reference
(together with any amendments, modifications, extensions, assignments, renewals or substitutions, the “Subject Lease”) for the premises located in St. Tammany Parish, Louisiana and Pearl River County, Mississippi, which premises are
more particularly described on EXHIBIT A attached hereto and incorporated herein by reference (the “Wet Facilities”). 
 GFES desires for ACG to mine, transport, and refine (collectively, “Process”) the sand removed from the Wet Facilities under the terms and conditions of this Agreement. GFES will commit
to cause ACG to mine, transport, and refine at least three million tons of Sand (as defined below) for GFES’ benefit. 

ACG will refine sand at the Dry Facility into 20/40 API quality sand (“20/40 Grade Sand”), 30/50 API quality sand
(“30/50 Grade Sand”), 40/70 API quality sand (“40/70 Grade Sand”), and 100 mesh API quality sand (“100 Mesh Sand”, together with the 20/40 Grade Sand, the 30/50 Grade Sand and the 40/70 Grade Sand, the
“Sand”). 
 The Sand will be refined at ACG’s refinery located on Highway 11, situated
in Section 22, T6S, R17W and the NW  1/4 of
Section 27, T6S, R17W, City of Picayune, Pearl River County, Mississippi (the “Dry Facility”). 

Agreement 

Now therefore, for good and valuable consideration, the Parties agree as follows: 

1. Construction of Mining Facility. ACG will provide and construct at its costs all necessary equipment (a) on the Wet Facilities needed to
mine, or cause to be mined, the Sand from the Wet Facilities, and (b) on the Dry Facility needed to refine and process the Sand delivered from the Wet Facilities. ACG will pay all costs and expenses associated with the mining, transporting,
refining, and Processing of the Sand. ACG will have the Wet Facilities and Dry Facilities fully operational and prepared to deliver Sand to GFES by June 22, 2012 (the “Mining Start Date”).

 2. Mine Operator. ACG is hereby designated as the mine operator of each of the Wet Facilities. ACG
will not have the right to assign or transfer any rights, duties or obligations of ACG to another party except with the consent of GFES, which such consent shall not be unreasonably withheld. GFES shall have the right of first refusal to lease, at
fair market value, the property and equipment comprising the Dry Facility and the equipment located on the Wet Facilities owned by ACG, in the event that (1) ACG becomes insolvent or unable to pay its debts as they mature or makes an assignment
for the benefit of creditors or commits any act of bankruptcy or seeks relief under laws providing for the relief of debtors; or (2) a receiver is appointed for ACG or for substantially all of its property and/or affairs; or (3) ACG has
committed a material breach of any substantive provision hereof or fails to perform its duties hereunder in a reasonable and prudent manner, or fails to rectify such default within thirty (30) days after notice from GFES. Prior to the effective
date of removal, ACG will deliver promptly to ACG’s successor the possession of everything owned by GFES pursuant to this Agreement. 

3. Authority and Duties of ACG 
 3.1 Exclusive right to operate. Unless otherwise provided herein, ACG will have the exclusive right and duty to conduct all operations pursuant to this Agreement. In performing services

3.2 Workmanlike conduct. ACG will conduct all operations in a good and workmanlike manner, as would a prudent ACG under the
same or similar circumstances. ACG will use its best equipment, personnel, and consumables (“Best Resources”) in the performance of the work and services under this Agreement, and GFES will have the priority over any third party for
the use of ACG’s Best Resources for up to 1,000,000 tons of Processed Sand per year, in accordance with Section 4.1. Unless otherwise provided, ACG will consult with GFES and keep it informed of all important matters. ACG will diligently

 3.7 Mining. ACG and/or any of its affiliates will employ its equipment and
personnel in the conduct of all mining operations, and will ensure all mining operations are conducted by qualified and responsible personnel. 
 3.8 Reports. ACG will make reports to governmental authorities that it has a duty to make and will furnish copies of such reports to GFES. ACG will give timely written notice to GFES of all
litigation and hearings of which it has notice affecting the Subject Lease or operations hereunder. 
 3.9 Safety.
ACG will perform, and will cause all ACG Personnel to perform, all work and services under this Agreement in accordance with the most stringent of safety regulations, precautions, and procedures reasonably practicable, employing all necessary or
desirable protective equipment and devices, whether suggested or required by safety associations, government agencies, municipalities, or otherwise. ACG will indemnify and hold GFES harmless from all citations or complaints which may be assessed
against GFES by any federal, state or other job-safety and health-enforcement agencies or by any ACG personnel based upon any and all alleged unsafe or unhealthy working conditions created or caused by ACG or ACG personnel, including holding GFES
harmless from any and all attorneys’ fees and other costs, damages, losses or liabilities of any kind incurred in connection with said citations or complaints. ACG will notify GFES of any incident arising out of or relating to the services
arising under this Agreement resulting in personal injury to any person or damage to or loss of personal property and will furnish GFES a report within a reasonable amount of time, of the incident summarizing all relevant facts. 

3.10 Information. ACG will furnish GFES the following information pertaining to each mine: 

(a) copy of any applications for permit to mine and all amendments thereto, and a copy of the permit issued; 

(b) copies of any test results, analyses or similar information generated by or for ACG; 

(c) copies of reports made to any regulatory agencies; 
 (d) records of all sand and aggregate removed from the Wet Facilities; and 
 (e)
all other reasonable information, available to ACG, pertaining to any sand or aggregate mined or processed pursuant to this Agreement. 

4. Quantity of Sand. 
 4.1. Right of First Refusal; Minimum Processing Amount. GFES shall have the right of first refusal on [***] tons of the Dry Plant capacity per year, with a minimum guarantee to Process [***] tons
of Processed Sand per month, which first delivery of Sand will be June 22, 2012. GFES expressly acknowledges that the general production capacity of a particular sand grade usually cannot exceed seventy percent (70%) of the overall
capacity of the Dry Facility (the “70% Threshold”). For example, if the monthly capacity of the Dry Facility is 100,000 tons, then the 70% Threshold would be 70,000 tons of a particular grade of Sand. ACG shall have the unrestricted rights
to the excess capacity of the Dry 
  
 *** Certain information in this
document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 3 

 
Facility, estimated to be approximately 200,000 tons per year (the “ACG Capacity”). Further, in the event that the Dry Facility capacity is expanded beyond the currently
estimated total capacity of 1,200,000 tons per year, ACG shall have the unrestricted rights to any and all expanded capacity in excess of said estimated total capacity. In no event with the ACG Capacity interfere with or delay the capacity to which
GFES has the right of first refusal. For the purposes of this Agreement, a “ton” equals 2,000 pounds. 
 4.2
Forecasts. Beginning April 1, 2012, and thereafter on or before the first day of January, April, July, and October of each calendar year, GFES will deliver to ACG a non-binding forecast prepared in good faith that sets forth the total
quantity of each type of Sand that GFES reasonably anticipates it will need to purchase from ACG during the following two calendar quarters (for example, the April forecast will include the months of April through September). ACG will, within
fifteen (15) days from receiving GFES’ forecast, provide its good faith analysis on the capability of Processing GFES’ forecasted needs, but only if such needs exceed the 70% Threshold. ACG’s analysis will be based on whether ACG
can exceed the general 70% Threshold, if requested by GFES. If no sand grades exceed the 70% Threshold, then ACG must Process the given amounts of Sand contained in the applicable forecasts. GFES will use its best efforts to notify ACG promptly
after any material change in any forecast delivered by GFES to ACG. 
 4.3 Additional Sand Purchase. ACG may elect to
purchase additional sand (the “Additional Sand”) from GFES at a price of [***] per ton for this raw “in ground” unprocessed sand located at the Wet Facilities. The Additional Sand must be processed at the Dry Facility.
Quantities and sand grades of Additional Sand must be agreed to in advance by GFES, which such consent shall not be unreasonably withheld. ACG will pay this [***] per ton for the Additional Sand within 30 days from proof of sale of the Additional
Sand. GFES will not need to invoice ACG for such Additional Sand, but ACG will promptly pay for the Additional Sand on its own, and will, in connection with such payment, provide proof of the tonnage of Additional Sand removed from the West
Facilities and any other documentation requested by GFES to ensure proper payment for the Additional Sand. Notwithstanding anything to the contrary contained herein, except to the extent of GFES’ right of first refusal provided for in
Section 4.1 above, no provision of this Agreement shall be interpreted to limit ACG’s right to Process Sand at the Dry Facility only to sand provided by GFES from the Wet Facilities or otherwise. 

5. Testing and Quality Assurance. ACG warrants that all Sand Processed for GFES under this Agreement will meet the standards of the API/ISO
specifications (“Specifications”) for fracturing sand in effect at the time of Processing of the Sand. GFES will have the opportunity to conduct independent API/ISO testing to ensure the quality of the Sand meets GFES’ requirements
prior to final payment. If GFES believes that any Sand mined and refined under this Agreement does not meet the quality set forth in this Agreement, it will notify ACG by telephone, confirmed in writing, not less than seventy-two (72) hours
after it receives any gradation report on the subject Sand. For the purposes of this Agreement, the Sand will be considered Processed, once it is mined and refined into API/ISO approved fracturing sand. 

In the event that a material change in the Specifications causes a change in the Processing cost, ACG and GFES will cooperate in good
faith to determine if an adjustment to the Processing Fee is warranted. The adjustment will be based on the increase or decrease in the actual direct costs associated with the Processing of the Sand as compared to the budgeted costs which gave rise
to the agreed on [***] per ton. The Processing Fee will be adjusted to an amount not to exceed the actual direct costs plus twenty five percent (25%), effective from the time of the adjustment. 

 
 *** Certain information in this document has been omitted and filed
separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 4 

 ACG will maintain on site effective laboratory means for the testing and verification of the
refined Sand according to industry approved API/ISO standards and specifications. ACG will test the Sand in accordance with the current customary procedures. The quality and sampling procedures utilized by ACG as of the date of this Agreement are
described on EXHIBIT B attached hereto. No changes may be made to these procedures without the consent of GFES. 
 ACG
will keep reasonably complete and accurate records regarding the testing of Sand as well as adequate samples of such Sand and ensure appropriate industry recognized sampling procedures and techniques are utilized and adhered to. GFES will have the
right, upon reasonable notice and during ACG’s business hours, to inspect such records to verify that, the Sand meets the Specifications. 

6. Term; Option to Extend. This Agreement will remain in effect until ACG Processes three million tons of Sand for GFES. GFES has the option to
extend this Agreement for two additional three million tons of Processed Sand once ACG Processes the initial three million tons of Sand for GFES. GFES must make such election in writing to ACG on or before GFES’ consumption of 2.6 million
tons of Sand. 
 7. Payment. GFES will pay to ACG a processing fee of [***] per ton (the “Processing Fee”), plus any and
all applicable sales tax, for all Sand ACG Processes for GFES. Thus, the total value of the [***] tons of Processed Sand at [***] per ton shall be [***], subject to adjustment as provided for in Sections 5 and 9. This Processing Fee will be
inclusive of all operating costs of the Wet Facilities and Dry Facility, including but not limited to, personnel, general operating expenses, capital equipment purchases, insurance, quality assurance programs, sampling and testing costs,
transportation costs, and any government required fees, permits, and licenses needed in connection with the Processing of the Sand. Said Processing Fee does not include the remobilization fee, or fee associated with resetting the mining site. ACG
will provide GFES with thirty (30) days prior notice of the need to remobilize and the estimated cost for such remobilization. GFES will reimburse ACG for the actual direct cost of such remobilization. Contemporaneous with the execution of this
Agreement, GFES will pre-pay ACG $4,000,000 towards the Processing Fees (the “Advance Fee”). In exchange for the Advance Fee, ACG will credit GFES [***] per ton of Processed Sand on all Sand Processed for GFES, and ACG will credit GFES
[***] per ton of Processed Sand for all third party Processed Sand sales, until a total of $4,000,000 is credited back to GFES. In no event shall the Advance Fee repayment exceed forty (40) months, at which time the outstanding balance of said
Advance Fee shall be due in full. Further, in the event that GFES exercises its right to lease and operate the Wet Facilities and Dry Facility pursuant to Section 2 herein, any outstanding balance owed on the Advance Fee shall be credited
toward the lease amount. 
 In the event that the GFES disputes with ACG any amounts, in whole or in part, attributable to an
invoice, or if an invoice submitted without proper supporting documents, GFES will not be obligated to pay the disputed amount to ACG until said dispute is resolved in accordance with this Agreement. GFES will notify ACG of the amounts in dispute
and/or the reason(s) the invoice is not acceptable and GFES will pay the undisputed amount. Upon resolution of the disputed amount, GFES will pay ACG the resolved amount or GFES will request ACG to issue a credit invoice for the unacceptable amount
of the disputed invoice. In the event a credit balance is owed by ACG to GFES, ACG will issue a credit memo to GFES for the amount of the credit. 
  

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has
been requested with respect to the omitted portions. 

  
 5 

 The payment terms are net 30 days. The payment due date will be calculated from the date an
invoice which is correct, proper, and prepared in accordance with the stated terms is received by GFES. Invoices for the Processing Fees will be received within 90 days of deliver of the Sand to GFES. 

8. FOB Delivery of Sand. Once the Sand is Processed according to the current Specifications, the Sand will be made available by ACG FOB rail or
truck at the Dry Plant. 
 9. Adjustment to Processing Fee. Within thirty days prior the one year anniversary of the Mining Start Date,
ACG and GFES will cooperate in good faith to determine if an adjustment to the Processing Fee is warranted. The adjustment will be based on the increase or decrease in the actual direct costs associated with the operation of the Wet Facilities and
the Dry Facility, including but not limited to, personnel, general operating expenses, insurance, quality assurance programs, sampling and testing costs, capital equipment purchases, transportation costs, and any government required fees, permits,
and licenses needed in connection with the Processing of the Sand as compared to the budgeted costs which gave rise to the agreed on [***] per ton. In no event will the adjustment to the Processing Fee exceed $6 per ton in either direction (i.e.,
[***] per ton will be the lowest adjusted Processing Fee and [***] will be the highest adjusted Processing Fee). The Processing Fee will be adjusted within these parameters to an amount not to exceed the actual direct costs plus twenty five percent
(25%). The adjustment to the Processing Fee will take effect one month after the first anniversary of the Mining Start Date.
