(b) Beginning on May 1, 2012 through July 31, 2014 (the “Secondary Period”) Supplier is obligated to sell and Halliburton is obligated to buy, a minimum annual volume of 600,000 tons of Product (the “Secondary Minimum Supply”) provided, however, such Secondary Miniumum Supply shall consist of no more than *** tons of ***.

Supplier shall be under no obligation to supply or sell Product in excess of the Initial Minimum Supply or the Secondary Minimum Supply. In the event that Supplier fails to supply to Halliburton either the Initial Minimum Supply or the Secondary Minimum Supply during any Contract Year (a “Supply Shortfall”), Supplier shall have *** after the end of such Contract Year to, as the sole and exclusive remedy for such Supply Shortfall, either (i) tender the Supply Shortfall, including by supplying Product from one or more third parties in accordance with Section 2.12, or (ii) pay to Halliburton within *** of the end of the Contract Year, as liquidated damages, an amount equal to amount of the Supply Shortfall (expressed in tons) multiplied by $***. It will be Supplier’s sole discretion as to which option is utilized.

(c) The “Monthly Maximum Supply Availability” during the Term is set forth in the table below. Supplier will not be obligated to fulfill orders that exceed the Monthly Maximum Supply Availability for a specific calendar month.

2.2 Supply Requirements; Price, Volume Discounts and Additional Volume.

(a) During the Term of this Agreement, pricing will be fixed at $***/short ton for contracted volumes as well as any additional material that becomes available for purchase by Halliburton.

(b) Supplier agrees that Halliburton shall be considered a preferred purchaser and, accordingly, prices paid by Halliburton during the Term of this Agreement shall be no greater than the lowest prices charged by Supplier for the same Product to any future purchasers in the oilfield services industry during any period covered by this Agreement. Notwithstanding the foregoing, this Section shall not apply to: (a) contracts paid in advance; or (b) contracts in place between Supplier and other customers before the Effective Date of this Agreement; or (c) to any spot sales made by Supplier; or (d) for sales of any Product offered to but not taken by Halliburton; or (e) sales of Product from facilities owned by Supplier at locations other than 0000 Xxxxx Xxxxxxx 000, Xxxxx, Xxxxxxxxx 00000.

(c) Subject to the availability of excess Product as determined by Supplier, Supplier may make available to Halliburton any additional volume, “Additional Volume” over the Monthly Maximum Supply Availability, on a right of first refusal basis. Supplier will provide its estimate of Additional Volume for delivery up to two months in advance of the actual availability and will use its best efforts to work with Halliburton regarding scheduling and delivery of such Additional Volumes.

2.3 Halliburton Minimum Purchase Requirement. During the Term, Halliburton shall be required to take and, in accordance with Section 3.1, pay for a minimum aggregate of 300,000 tons of Product during the Initial Period and 600,000 tons of Product per Contract Year for the Secondary Period (the “Minimum Purchase Requirement”); provided, however, that if, due solely to Force Majeure or the unavailability of rail cars in the market, Halliburton is unable to take delivery of Products as contemplated hereunder for a period of time during a Contract Year, Halliburton shall not be deemed to be in breach of this Agreement as a result of such failure so long as Halliburton is using best efforts to obtain rail cars and minimize the period of time during which Halliburton is unable to take delivery of Products; provided, further, however, that nothing in this sentence shall be construed to relieve Halliburton of its obligations to make payments under this Agreement (including the obligation to make any Makewhole Payments as contemplated in Section 2.6).

2.4 During the Initial Period, the Minimum Purchase Requirement shall be ordered by Halliburton in installments of not less than 25,000 tons of Product per calendar month (the “Initial Monthly Minimum Requirement”), and not more than the Monthly Maximum Supply Availability, beginning in September of 2011 and continuing thereafter for each calendar month during the Initial Period. In the event that Halliburton fails to purchase one ninth (1/9) of the Minimum Purchase Requirement of Product from Supplier during any particular calendar month in the Initial Period in which Supplier was ready, willing and able to deliver 33,333 tons of Product, then the “Purchase Shortfall” shall be the amount by which one ninth (1/9) of the Minimum Purchase Requirement exceeds the amount of Product actually purchased by Halliburton during such calendar month.

2.5 During the Secondary Period, the Minimum Purchase Requirement shall be ordered by Halliburton in installments of not less than 40,000 tons of Product per calendar month (the “Secondary Monthly Minimum Requirement”), and not more than the Monthly Maximum Supply Availability, beginning in May of 2012 and continuing thereafter for each calendar

pg. 5

month during the remaining Term of this Agreement. In the event that Halliburton fails to purchase one twelfth (1/12) of the Minimum Purchase Requirement of Product from Supplier during any particular calendar month in the Secondary Period in which Supplier was ready, willing and able to deliver 50,000 tons of Product, then the “Purchase Shortfall” shall be the amount by which one twelfth (1/12) of the Minimum Purchase Requirement exceeds the amount of Product actually purchased by Halliburton during such calendar month until the minimum annual volume is met.

2.6 On written notice of such Purchase Shortfall to Halliburton by Supplier, Halliburton shall have *** after the month of the Purchase Shortfall to purchase tonnage of Product in excess of the Initial or Secondary Monthly Minimum Requirement as applicable (but subject to the Monthly Maximum Supply Availability) to make up for the Purchase Shortfall. If Halliburton fails to purchase the full amount of the Purchase Shortfall in such *** period, Halliburton shall be obligated to pay to Supplier an amount equal to the amount of the Purchase Shortfall not purchased by Halliburton in such *** period (expressed in tons) multiplied by $*** (the “Makewhole Payment”). The Makewhole Payment shall be paid within *** of written demand by Supplier, by wire transfer of immediately available funds to the account designated in writing by Supplier. The aggregate Purchase Shortfall amount for a Contract Year shall not exceed the Initial or Secondary Minimum Purchase Requirement for such Contract Year, as applicable, less the amount of Product ordered and delivered to Halliburton. Halliburton reserves the right to resell goods purchased from Supplier if deemed necessary by Halliburton in order to satisfy the Initial or Secondary Minimum Purchase Requirement. Supplier shall not be obligated to deliver more than the Monthly Maximum Supply Availability on any given calendar month.

2.7 Halliburton may elect to sell all or any amount of Product comprising the Minimum Purchase Requirement in order to meet its obligations under this Agreement. If requested by Halliburton, Supplier will use its best efforts to assist Halliburton with delivery schedules and delivery locations for any Product sold by Halliburton. Sales of such Product by Halliburton will count towards fulfilling Halliburton’s Minimum Purchase Requirement. Nothing in this Section will release Halliburton from its payment obligations to Supplier for such Product sold by Halliburton.

2.8 Forecast of Demand. Halliburton shall provide, on a quarterly basis, a non-binding 3-month rolling volume forecast of its anticipated purchase of Products (“Forecast Amount”). Updates to the Forecast Amount indicated in the six-month rolling volume forecast will be made and communicated periodically outside of the three-month rolling volume forecast as promptly as practicable after Halliburton becomes aware of such changes. Supplier shall notify Halliburton within ten (10) Business Days of receiving a forecast or update if Supplier anticipates being unable to meet the anticipated purchase amounts. Supplier shall not be obligated to deliver more than the Monthly Maximum Supply Availability on any given calendar month.

2.9 Title and Risk Of Loss. Title and risk of loss or damage to Products shall pass to Halliburton as defined by Incoterm, FCA (details listed in table below), Incoterms 2010.

Such changes shall be effective for that Work Order only. Printed terms and conditions contained in documents issued to Halliburton by Supplier or from Halliburton to Supplier with respect to the Products shall be of no force and effect and shall be superseded by the terms and conditions which are contained in this Agreement.

If Halliburton is not then in breach of this Agreement giving rise to an event of termination, this Agreement may be immediately terminated for breach if Supplier fails to produce and deliver Products that meet the Specifications for a period of more than ***. Upon such breach, Halliburton may terminate this Agreement immediately by giving written notice of termination to Supplier.

In the event Supplier has incurred costs in executing the Work Order up to termination, Halliburton shall reimburse Supplier for such documented costs. In the event of Supplier’s failure to perform any of its material obligations under this Agreement (including failure to deliver agreed upon amounts of sand and not making up the Supply Shortfall as contemplated by Section 2.1(b),), Halliburton shall promptly give Supplier notice thereof. Such notice shall specifiy the nature of such failure with particularity and in reasonable detail, including the specific provision of this Agreement to which such purported failure relates. Suplier shall use commercially reasonable effort to cure or otherwise remedy the failure specified in such notice within *** after its receipt of such notice. A failure specified in such notice which Supplier does not cure or otherwise remedy in such *** period shall be deemed a “Supplier Uncured Failure”. Halliburton shall have the right to terminate this Agreement if Supplier has more than ***. Halliburton’s sole and exclusive damages in case of such termination shall be limited to $*** per short ton of Product that remains undelivered under the Minimum Purchase Requirements for the remaining life of the Contract after the filling of all outstanding Work Orders. The Parties acknowledge and agree that in the event of a breach under this Section 8.2, the damages would be difficult if not impossible to quantify, and accordingly, such payment shall be for liquidated damages and not as any form of penalty.

8.3 Termination by Supplier. If Supplier is not then in breach of this Agreement giving rise to an event of termination, Supplier shall be entitled to terminate this Agreement should Halliburton fail to order and take delivery of Product or pay sums due hereunder. Supplier shall give Halliburton written notice of any such failure and provide a reasonable time to cure which shall not exceed ***. Should Halliburton fail to cure prior to the end of such *** period, then Supplier may terminate this Agreement immediately.

The Parties acknowledge and agree that in the event of a breach under this Section 8.3, the damages would be difficult if not impossible to quantify, and accordingly, such payment shall be for liquidated damages and not as any form of penalty.

8.4 Termination of Work Order. A termination of a Work Order does not terminate this Agreement. A termination of this Agreement does not terminate any existing Work Order until such Work Order is completed, unless such Work Order is expressly terminated also.

8.5 Events Upon Termination.

(a) Upon expiration of this Agreement or the termination of the Agreement for reasons other than pursuant to Section 8.2, Halliburton shall purchase from Supplier all Products which have been ordered from Supplier but not delivered to Halliburton at the date of termination, and Supplier shall promptly manufacture and deliver such Products to Halliburton.

pg. 14

9.2 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR, AND EACH PARTY RELEASES THE OTHER FROM LIABILITY ATTRIBUTABLE TO, ANY SPECIAL, ECONOMIC, INDIRECT, CONSEQUENTIAL, OR OTHER INCIDENTAL DAMAGES ARISING OUT OF THE PERFORMANCE OF THIS AGREEMENT, OR DEFAULT IN THE PERFORMANCE HEREOF, WHETHER BASED UPON CONTRACT, TORT (INCLUDING NEGLIGENCE, PRODUCT LIABILITY OR STRICT LIABILITY), OR WARRANTY.

9.3 Indemnification Procedure. In the event either Party learns of any claim, liability, demand or cause of action relating to this Agreement or the performance hereunder, which said Party shall determine, in its sole discretion, that the other Party may be liable therefor, said Party shall promptly notify the other Party. If indemnity is required by any of the terms of this Agreement, the indemnifying Party shall have the right to control all litigation and shall defend the other and pay all settlements, judgments, costs, and expenses (including without limitation court costs and reasonable attorneys’ fees), whether related or unrelated, similar or dissimilar to the foregoing, incident thereto. Each Party, if requested, agrees to cooperate with the other in any defense, and the indemnifying Party shall reimburse the other for all reasonable expenses incurred in connection therewith. The indemnified Party shall have the right to have counsel of its own choosing and at its sole expense participate in any such litigation. Notwithstanding the foregoing, however, neither Party shall effect settlement of or compromise any such claim or proceedings without having obtained the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed; provided that the indemnifying Party may settle or compromise any such claim if the settlement or compromise (a) requires solely the payment of money damages by the indemnifying Party, and (b) includes as an unconditional term thereof the release by the claimant or the plaintiff of the indemnified Party from all liability in respect of such claim. If the indemnified Party does not consent to a settlement which the indemnifying Party is willing to accept, then the indemnifying Party’s liability shall be limited to the amount for which the claim could have been settled provided, such settlement does not require the indemnified Party to forego any property rights other than the amount of payment of the proposed settlement.

9.4 Compliance with Law. Subject to the limitations of this Agreement, it is agreed that in the performance of this Agreement all matters shall be conducted in full compliance with any and all applicable federal, state, provincial and local laws, rules and regulations in the area(s) in which the matters are being conducted. Any performance obligation arising under this Agreement is contingent on the prior receipt of all necessary government authorizations. If either Party is required to pay any fine or penalty or is subject to a claim from the other Party’s failure to comply with applicable laws, rules or regulations, the Party failing to comply shall defend, indemnify and hold harmless the other Party for all damages, fees and/or fines for such failure to comply to the extent of the indemnifying Party’s allocable share of the failure to comply.

9.5 Antibribery. Supplier represents and warrants that it and all of its Affiliates and agents shall act in accordance with the principles described in the Convention on Combating Bribery of Foreign Public Officials in International Business Transactions, signed in Paris on December 17, 1997 (“the Convention”), and the Convention’s Commentaries (collectively the “OECD Principles”), and shall comply with all applicable laws implementing the OECD Principles (including the U.S. Foreign Corrupt Practices Act of 1977), as well as any applicable local laws related to anti-corruption, anti-kickbacks, and anti-money laundering. Supplier agrees not to take or fail to take any action that might

pg. 15

cause Halliburton to be in violation of any such laws. In addition to the foregoing, Supplier represents and warrants that it and its Affiliates have not and shall not request, induce, make, offer, authorize, promise to make any payment or transfer anything of value, directly or indirectly, (a) to any governmental official or employee (including employees of government-owned or government-controlled corporations, agencies or bodies), (b) any official or employee of a public international organization, (c) to any political party, official of a political party or candidate, or (d) to any third party knowing, believing, or suspecting that such third party will give the payment, or any portion thereof, to any of the foregoing persons in order to obtain or retain business, or for any other improper purpose. Any payments to governmental officials or employees on behalf of Halliburton must be promptly reported to Halliburton.

9.6 Code of Conduct/ Gifts, Entertainment and Travel. It is considered to be in conflict with Halliburton’s interest for its employees or any member of their immediate family to accept gifts, payments, extravagant entertainment, services, or loans in any form from anyone soliciting business, or who may already have established business relations with Halliburton. Gifts of nominal value and entertainment, meals, and social invitations that are customary and proper under the circumstances and that do not place the recipient under any obligation are acceptable. Any gifts, payment of individual expenses, including, without limitation, trips, or conveyances to Halliburton employees shall be disclosed in writing to the Halliburton Ethics and Compliance Group.

9.7 Information Requests. Supplier shall maintain full and complete accounting records of activity performed and expenditures incurred by Supplier in connection with this Agreement in such a manner and detail as to permit verification of compliance with the performance obligations, including, by way of illustration and not limitation, pricing requirements, as well as the provisions of Sections 9.4 through 9.6 of this agreement. Halliburton shall have the right to audit such Supplier’s records for a period of two (2) Years from the expiration or termination of this Agreement. This provision shall survive expiration or termination of this Agreement.

Notwithstanding anything to the contrary, neither Party shall be required to take or refrain from taking any action prohibited or penalized under the laws of the United States, including the U.S. antiboycott laws.

9.8 Economic Sanctions and Export Controls. Supplier agrees to fully comply with all economic sanctions and export control laws and regulations, including those regulations maintained by the U.S. Commerce Department’s Bureau of Industry and Security and the U.S. Treasury Department’s Office of Foreign Assets Control. In addition, Supplier shall not, directly or indirectly, sell, provide, export, re-export, transfer, divert, loan, lease, consign or otherwise dispose of any Halliburton equipment, product, services, software, source code, technical data or technology to or via any person, entity or destination, or for any activity or end-use restricted by the laws or regulations of the United States or any other applicable jurisdiction (including nuclear, missile, chemical or biological weapons proliferation, military, or money laundering activities) without first obtaining all required government authorizations.

10. Nature of Agreement

10.1 Assignment. Either Party shall have the right to assign or transfer to any Person any of its rights or obligations under this Agreement without the prior written consent of the other Party, provided that the assigning Party shall remain liable to the other

pg. 16

Party under the terms of this Agreement notwithstanding such assignment. This Agreement shall be binding on and inure to the benefit of the Parties and their respective successors and permitted assigns, including any successor upon a sale or change of control of a Party. This Agreement is intended solely for the benefit of the Parties and their respective successors and permitted assigns.

10.2 Relationship. Each of the Parties is an independent contractor with respect to the other and is not an employee of the other Party or any of the other Party’s Affiliates, and nothing in this Agreement is intended to constitute a partnership or a master and servant relationship between the Parties. Each of the Parties understands and agrees that this Agreement does not create an exclusive dealings arrangement and that each of Halliburton and Supplier may enter into similar arrangements with other companies with respect to similar or the same products. Nothing in this Agreement shall be construed to create any duty to, or standard of care with reference to, or liability of a Party to, any person not a Party to this Agreement. Nothing in this Agreement shall be deemed to constitute any fiduciary or special relationship or duty between the Parties and each Party may take actions hereunder that are for its own self-interest without any duty or, subject to the express terms of this Agreement, liability to the other Parties.

10.3 Entire Agreement; Amendment. This Agreement, including its appendices, exhibits and schedules, constitutes the entire Agreement between the Parties with respect to the subject matter hereof and supersedes any existing agreements between them whether oral or written. The terms of this Agreement shall only be amended, modified or supplemented as set forth herein or in a writing signed by or on behalf of both or the Parties. In case of a conflict between this Agreement and a purchase order (Work Order) or purchase order confirmation contemplated hereunder, the terms of this Agreement shall govern. Acceptance of a Work Order or purchase order confirmation is insufficient to amend this Agreement unless a separate writing is duly executed by all the Parties specifically amending this Agreement.

10.4 Reformation. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated hereby are not affected in any manner materially adverse to any Party. Upon the determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible. In the event any such provision, clause, sentence or part of this Agreement cannot be modified to comply with the law, then said provision, clause, sentence or portion of the Agreement shall be deemed to be deleted from the Agreement and the remaining terms and conditions shall remain in full force and effect.
