	1.3	Condition Precedent to Payment of Invoice: Prior to submitting an invoice for the First Prepayment to Encana. Contractor will provide Encana with evidence of
Contractor’s ability to pay the purchase price for the Fleets (as defined in the Work Order) to be used by Contractor to perform the Work under the Work Order. Such evidence will be in the form of either: (i) a funding commitment

 letter from Contractor’s bank evidencing, to Encana’s reasonable satisfaction, that Contractor’s
bank has committed to provide funds in an amount sufficient to purchase the Fleets (the “Commitment”); or (ii) financial information showing to Encana’s reasonable satisfaction that Contractor has the ability to purchase the
Fleets. Contractor will notify Encana immediately if the Commitment is withdrawn or reduced in any way. Encana will have no obligation to make any prepayments under this Agreement until Contractor has provided evidence as set forth herein or if the
Commitment is withdrawn or reduced in any way. If Contractor cannot provide evidence reasonably satisfactory to Encana that this condition has been satisfied by [December 31, 2010], Encana may, at its sole option, terminate the MSA and Work Order
without further obligation of any kind to Contractor. 
  

	1.4	Second Prepayment: Encana will also pay Contractor the amount of $* 30 Days prior to the Initial Delivery Date (as defined in the Work Order) (the

 (b) Upon the expiration of the term of the Work Order, the Remaining Credit Balance will be credited to the entire amount of
any unpaid invoices for the Work. If there is still a Remaining Credit Balance and Contractor provides other services to Encana unrelated to the Work Order, the Remaining Credit Balance will be credited to the unpaid and future invoices for said
other services until the entire Remaining Credit Balance has been credited. If there is still a Remaining Credit Balance and

AFFORDED TO IT AGAINST CONTRACTOR IN CONNECTION WITH THIS CONTRACT, OTHER THAN FOR BREACH OF WARRANTY. 
 D. Compliance with Laws. Contractor agrees at all times in the performance of this contract to abide by all laws, rules and regulations, whether federal, state or local which now or in the future
may be applicable to the Work and/or the geographic area where the Work is to be performed and to remedy any violation or such laws, rules and regulations within a reasonable time and to pay and discharge all charges, penalties and fines imposed or
levied upon Petrohawk as a result of such alleged violation or violations, specifically including any such fines, levies or penalties assessed as a result of any federal, state or local governmental or health, safety and/or environmental act.
Contractor’s obligations under this section shall include, but shall not be limited to, the obligations set forth on Exhibit “B” and Exhibit “C” (to the extent applicable), both attached hereto and made a part hereof as if
fully set forth herein.

and services for purposes of La. R.S. 23:1061(a)(1). Furthermore, the parties agree that Petrohawk is the statutory employer of Contractor’s employees solely for the purposes of La. R.S. 23:1061(a)(3) and not for any other purposes whatsoever.
Irrespective of Petrohawk’s status as the statutory employer or special employer (as defined in La. R.S. 23:1031(c)) of Contractor’s employees, Contractor agrees to remain primarily responsible for the payment of Louisiana Workers’
Compensation benefits to its employees, and shall not be entitled to seek contribution for any such payments from Petrohawk. Further, Contractor agrees to defend, indemnify and hold harmless Petrohawk from any and all claims for compensation
benefits by Contractor’s employees against Petrohawk and hereby waives any right of Contractor or of Contractor’s insurers to seek reimbursement of any compensation benefits owed or paid.

 H. Indemnity Limitations. The obligation of a party hereto to indemnify the other
party against such other party’s negligence shall only be effective to the maximum extent permitted by the applicable law, either legislative enactment or a controlling judicial decision. If any such existing or future law limits the extent to
which indemnification may be provided to an party that is negligent, solely negligent, or otherwise at fault and, notwithstanding the choice of law provisions set forth herein, such law is applicable to the interpretation of this Contract, then this
Contract shall automatically be amended to provide that the indemnification obligation provided hereunder shall extend only to the maximum extent permitted by such law. In addition, except as otherwise provided herein the terms and provisions
hereunder shall have no applicability to claims or causes of action asserted against Petrohawk or Contractor by reason or any agreement of indemnity with a person or entity not a party hereto. 

I. Texas Anti-Indemnity Act. If operations are performed in Texas or under Texas law, both parties. agree that in order to be in compliance with the Texas Oilfield

insurance requirements set forth on Exhibit “A” attached hereto and made a part hereof for all purposes. If the monetary limits of insurance required hereunder exceed the monetary limits permitted by law, then the monetary limits of
insurance required hereunder shall be deemed automatically reduced to the limits permitted by law. 
 J. Insurance
Generally. The parties agree to obtain and maintain insurance coverage in an amount sufficient to satisfy the requirements set forth on Exhibit “A” attached hereto. Commencement of operations without the required certificates of
insurance or without compliance with any other provisions of this Contract shall not constitute a waiver of any rights under this contract. The insolvency, bankruptcy, or failure of any insurance company, or the failure of any insurance company to
pay claims accruing, shall not be held to affect, negate, or waive any of the provisions of this Contract. Contractor shall cause all its subcontractors to carry and maintain insurance of the type and in not less than the amounts which Contractor is
required to carry and maintained hereunder. 
 K. Indemnity Procedure. In the event a party must bring legal action in
order to enforce an indemnification, all reasonable costs and expenses related to that action shall be included as part of the indemnification. If a claim is asserted against one of the parties to this Contract which may give rise to a claim for
indemnity against the other party hereto, the party against whom the claim is first asserted must notify the potential indemnitor in writing and give the potential indemnitor the right to defend the defense of the claim. With respect to the defense
obligations of the respective parties hereunder, the indemnitor shall indemnify the indemnitee hereunder for any claims, demands, causes of notion covered by the provisions set forth herein; provided, however, that the indemnified
party reserves the right, at its option, to participate at its own expense, with attorneys of its choice, in the defense of any such claims, demands, or causes of action without releasing the other party from any indemnity obligations hereunder;
provided, further, however, that the party obligated under such indemnity obligation to provide defense to the other shall have exclusive control of the defense and settlement of any such claim, demand, or cause of action, insofar as,
and to the extent that, such indemnitor is liable for payment of

L. Limitation of Consequential Damages. Except as otherwise provided in the second sentence of this paragraph, neither party shall
be liable to the other party for, and each party hereby releases the other party from, any and all indirect, special, punitive, exemplary or consequential damages or losses (collectively, “Consequential Damages”) incurred by such
party, Regardless of Fault. The limitation against Consequential Damages stated in the immediately preceding sentence shall not apply to “pass-through” claims for Consequential Damages that could otherwise be made under the
“knock-for-knock” indemnity provisions of Paragraphs 4.B. and 4.C. above. 
 M. Marcel Exception. For Work or
services to be performed in Louisiana or for which Louisiana Revised Statue 9.2780 (Louisiana Oilfield Anti-Indemnity Act) would apply, Petrohawk agrees that it will, on behalf of Company Group, pay the premium for the extension of Contractor’s
insurance to cover Company Group as an additional insured to the extent of the liabilities assumed by Contractor herein, and Contractor agrees that its insurers will invoice Petrohawk the premium for such extension of coverage in favor of Company
Group. Contractor warrants that such premium shall constitute all material costs for such extension of coverage. At each subsequent renewal, Contractor shall advise Petrohawk as respects the amount for the premium required for such extension of
coverage and shall arrange to have Petrohawk billed for the all material costs of the premium for such extension of coverage to Company Group. For any Work or services to be performed in Louisiana or for which the Louisiana Revised Statute 9.2780
(Louisiana Oilfield Anti-Indemnity Act) would apply, Contractor agrees that it will, on behalf of Contractor Group, pay the premium for the extension of Petrohawk’s insurance to cover Contractor Group as an additional insured to the extent of
the liabilities assumed by Petrohawk herein, and Petrohawk agrees that its insurers will invoice Contractor the premium for such extension of coverage in favor of Contractor Group. Petrohawk warrants that such premium shall constitute all material
costs for such extension of coverage. At each subsequent renewal, Petrohawk shall advise Contractor as respects the amount for the premium required for such extension of coverage and shall arrange to have Contractor billed for the all material costs
of the premium for such extension of coverage to Contractor Group.

indemnity, defense and release provisions set forth in this Paragraph 4 shall be the exclusive remedy/remedies available to the parties for the claims covered by such provisions, provided, however; the provisions set forth in this Paragraph 4 are
not intended to preclude, or otherwise restrict a party hereto from pursuing actions against the other parties to this Contract for claims otherwise permitted under this Contract, such as breach of contract, breach of warranty and/or breach or
confidentiality (non-exclusive examples). 
 O. Accident Reports. Contractor will immediately provide written notice to
Petrohawk of any accidents or occurrences resulting in injuries, illnesses, or deaths to persons or damage and/or loss to property in any way arising out of or related to Contractor’s operations or the operations of any subcontractor in
