Schedule 3

SERVICE FEES AND REIMBURSABLE

EXPENSES DURING SUSPENSION PERIOD

Suspension of Services During the Period January 1, 2016 through March 31, 2016 (the “Suspension Period”).

Notwithstanding anything contained in the A/R MSA Agreement or Exhibit B to the contrary, during the Suspension Period, Company intends to reduce its completion activities, including the Services provided by Contractor; and consequently Company and Contractor have agreed to suspend any Services under the A/R MSA Agreement during the Suspension Period on the following terms:

(a) Suspension of Services. The Parties hereby agree that during the Suspension Period, (i) Contractor shall not provide any Services to Company under the A/R MSA Agreement, and (ii) Contractor may use the Dedicated Frac Spreads for other customers (but is under no obligation to do so). As a consequence of such suspension of Services, the Parties agree to revise the Service Fees and Reimbursable Expenses that would otherwise be due by Company during the Suspension Period in accordance with the following terms of this Schedule.

(b) Payment of Monthly Deposits. Each calendar month during the Suspension Period Company will pay to Contractor a non-refundable deposit equal to $[*]¹ (each “Monthly Deposit Amount”, in the aggregate the “Deposit”). The Monthly Deposit Amounts for January and February will be due February 22, 2016, and the Monthly Deposit Amount for each subsequent month during the Suspension Period shall be due within ten (10) days of the beginning of each such month. Except with respect to January and February 2016, Contractor shall submit a written invoice to Company for the Monthly Deposit Amounts payable with respect to each calendar month prior to the beginning thereof. Commencing on April 1, 2016 and continuing through September 30, 2016 (the “Catch-up Period”), Contractor shall apply $[*]¹ of the Deposit per calendar month towards the fixed monthly service fees due and payable by Company to Contractor pursuant to Exhibit B (as amended by Section 1(c) below).

(c) Revisions to Fixed Monthly Fee. The Parties agree that during the Suspension Period the monthly fee of $[*]¹ per Dedicated Frac Spread (which is part of the Services Fees) shall be [*]¹, and that the monthly fee for the Catch-up Period shall be [*]¹ per Dedicated Frac Spread to $[*]¹ per Dedicated Frac Spread. After the end of the Catch-up Period, the fixed monthly fee will be $[*]¹ per Dedicated Frac Spread plus any applicable CPI adjustment, as provided in Exhibit B.

(d) Revision to Direct Costs Payable During the Suspension Period. The Parties agree that all of the “Direct Costs” (as defined in Exhibit B) incurred by Contractor during the Suspension Period will be abated and paid ratably over the Catch-up Period, subject to the following provisions:

(i) Notwithstanding the provisions of Exhibit B, for the Suspension Period the Parties agree that the total repair and maintenance under Exhibit B shall be fixed at $[*]¹, in the aggregate, and shall not be based on or reconciled to actual costs for repair and maintenance of the Dedicated Frac Spreads. The other Direct Costs incurred by Contractor during the Suspension Period shall be determined in accordance with Exhibit B.

(ii) If Contractor uses either or both Dedicated Frac Spreads for other customers during the Suspension Period, then to the extent that Contractor is paid for any of the personnel related expenses that are included in the Direct Costs by such other customer, such amounts (as reasonably determined by Contractor in accordance with its normal accounting practices) shall directly reduce the corresponding Direct Costs to be paid by Company during the Catch-up Period, under subsection (iii) below.

(iii) Within ten (10) days after the end of the Suspension Period, Contractor will provide to Company a statement of all of the Direct Costs that were abated during the Suspension Period as described above and not otherwise offset in accordance with subsection (ii) above (the “Total Abated Amount”). Company shall pay Contractor the Total Abated Amount in [*]¹ equal monthly installments, which shall be billed and paid in conjunction with Contractor’s regular invoices for those months in the Catch-up Period. Upon Company’s tender of the final installment in connection with the Total Abated Amount, the Parties agree that Company will have fulfilled all of its obligations to Contractor for the Suspension Period under the A&R MSA Agreement and this Amendment. By way of example, if the Total Abated Amount was $[*]¹ (compromised of $[*]¹ in repair and maintenance and $[*]¹ of other Direct Costs incurred during the Suspension Period and not offset under subsection (ii)), the quotient of $[*]¹ divided by [*]¹ would be $[*]¹. Therefore under this example, Contractor would include an itemized charge of $[*]¹ on each of its [*]¹ regular monthly invoices directed to Company during the Catch-up Period.

(iv) If the A/R MSA Agreement is terminated for any reason prior to the end of the Catch-up Period, then any unpaid portion of the Total Abated Amount shall be immediately due and payable by Company, and any unused portion of the Deposit shall be forfeited and shall be retained by Contractor without any offset or reduction to any other amounts owed by Company under the A/R MSA Agreement.
