4. Disbursement of Escrow Funds. 
 (a) Completion of Williston Basin Acquisition. Subject to the following sentence, if, prior to December 31, 2012, the Company delivers to Escrow Agent a Release Certificate, Escrow Agent will
liquidate the Escrow Funds then held by it and disburse all Escrow Funds according to the payment instructions contained in the Release Certificate. The Company shall provide Escrow Agent at least two Business Days prior notice of the anticipated
delivery of the Merger Certificate, unless otherwise agreed by Escrow Agent.

Escrow Agent receives the Special Mandatory Redemption Notice, then Escrow Agent will disburse all Escrow Funds directly to the Paying Agent on or before 11:00 a.m., New York City time, on the date fixed for the Special Mandatory Redemption
specified in such notice. If Escrow Agent receives a notice of a Special Mandatory Redemption, Escrow Agent will liquidate the Escrow Funds then held by it sufficiently prior to the mandatory redemption date, and in any event no later than the

 (c) If the Escrow Agent receives a notice from the Trustee that the principal of and accrued
interest on the Notes (the “Default Amount”) has become immediately due and payable pursuant to Section 6.2 of the Indenture and either (i) a court of competent jurisdiction by final and nonappealable judgment determines
that the acceleration of the Notes was appropriate as a result of a bona fide Event of Default under the Indenture or (ii) such acceleration is not rescinded on or prior to December 31, 2012, the Escrow Agent will promptly liquidate all
Escrow Funds then held by it and will release to the Paying Agent for payment to the holders of the Notes an amount of Escrow Funds sufficient to pay the Default Amount. 
 5. Suspension of Performance; Disbursement Into Court. If, at any time, there exists any dispute with respect to the holding or disposition of any portion of the Escrow Funds or any other
obligations of Escrow Agent hereunder, or if at any time Escrow Agent is unable to determine, to Escrow Agent’s sole satisfaction, the proper disposition of any portion of the Escrow Funds or Escrow Agent’s proper actions with respect to
its obligations hereunder, or if Trustee has not within 30 days of the furnishing by Escrow Agent of a notice of resignation under Section 7 hereof, appointed a successor Escrow Agent to act hereunder, then Escrow Agent may, in its sole
discretion, take either or both of the following actions: 
 (a) suspend the performance of any of its obligations (including
without limitation any disbursement obligations) under this Agreement until such dispute or uncertainty has been resolved to the sole satisfaction of Escrow Agent or until a successor Escrow Agent has been appointed (as the case may be); provided
however, that Escrow Agent will continue to invest the Escrow Funds in accordance with Section 6 hereof; and/or 
 (b)
petition (by means of an interpleader action or any other appropriate method) any court of competent jurisdiction, in any venue convenient to Escrow Agent, for instructions with respect to such dispute or uncertainty, and, to the extent required by
law, pay into such court, for holding and disposition in accordance with the instructions of such court, all Escrow Funds held by it. 
 Escrow Agent will have no liability to the Company, the holders of the Notes or any other person, except for Escrow Agent’s fraud, willful misconduct or gross negligence, with respect to any such
suspension of performance or disbursement into court, specifically including any liability or claimed liability that may arise, or be alleged to have arisen, out of or as a result of any delay in the disbursement of Escrow Funds or any delay in or
with respect to any other action required or requested of Escrow Agent. 
 6. Investment of Funds. The Company may from
time to time instruct Escrow Agent in writing to invest the Escrow Funds from time to time in the investments indicated on Exhibit B attached hereto, which investments shall be made in the name of the Company. In the absence of such
direction, the funds shall remain uninvested. Escrow Agent may, without notice to the Company, liquidate any investments held in order to provide funds necessary to make required payments under this Agreement. All investment earnings shall become
part of the Escrow Funds and investment losses shall be charged against the Escrow Funds. Escrow Agent shall not be liable for losses, penalties or charges incurred upon any sale or purchase of any such investment except for Escrow Agent’s
fraud, willful misconduct or gross negligence. 

  
 3 

 Except as otherwise set forth herein, Escrow Agent does not have any interest in the Escrow
Funds deposited hereunder but is serving as escrow holder only and having only possession thereof. The Company will pay or reimburse Escrow Agent and Trustee upon request for any transfer taxes or other taxes relating to the Escrow Funds incurred in
connection herewith and will indemnify and hold harmless Escrow Agent and Trustee with respect to any amounts that it is obligated to pay in the way of such taxes, in each case to the reasonable satisfaction of Escrow Agent and Trustee. Any payments
of income from the Escrow Account will be subject to United States federal withholding tax regulations then in force. The Company will complete and provide Escrow Agent with an appropriate W-9 form for taxpayer identification number certifications,
or W-8 forms for non-resident alien certifications, as requested. It is understood that Escrow Agent will be responsible for income reporting only with respect to income earned on investment of funds which are a part of the Escrow Funds and is not
responsible for any other reporting. All interest or other income earned under this Agreement shall be allocated to the Company and reported, as and to the extent required by law, by Escrow Agent to the Internal Revenue Service (“IRS”), or
any other taxing authority, on IRS Form 1099 or 1042-S (or other appropriate form) as income earned from the Escrow Funds by the Company whether or not said income has been distributed during such year. Any other tax returns required to be filed
will be prepared and filed by the Company with the IRS and any other taxing authority as required by law. The parties acknowledge and agree that Escrow Agent shall have no responsibility for the preparation and/or filing of any income, franchise or
any other tax return with respect to the Escrow Account or any income earned by the Escrow Funds. Escrow Agent shall withhold any taxes it deems appropriate, including but not limited to required withholding in the absence of proper tax
documentation, and shall remit such taxes to the appropriate authorities. The provisions of this paragraph will survive the termination of this Agreement or the earlier resignation or removal of Escrow Agent. 

7. Resignation of Escrow Agent. Escrow Agent may resign from the performance of its duties hereunder at any time by giving ten
Business Days’ prior written notice to Trustee and the Company. Such resignation will take effect upon the appointment of a successor Escrow Agent as provided herein below. Within ten Business Days of any such notice of resignation, the Company
will appoint a successor Escrow Agent hereunder, which shall be a commercial bank, trust company or other financial institution with a combined capital and surplus in excess of $250.0 million. If the Company has failed to appoint a successor Escrow
Agent within the ten Business Days following the delivery of the Escrow Agent’s notice of resignation, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor Escrow Agent or for other appropriate
relief, and any such resulting appointment shall be binding upon the Company. 
 8. Successor Escrow Agent. On the
acceptance in writing of any appointment as Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow Agent will succeed to and become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent under this
Agreement, and the retiring Escrow Agent will be discharged from its duties and obligations under this Agreement, but will not be discharged from any liability for actions taken as Escrow Agent hereunder prior to such succession. After any retiring
Escrow Agent’s resignation, the provisions of this Agreement will inure to its benefit as to any actions taken or omitted to be taken by it while it was Escrow Agent under this Agreement. The retiring Escrow Agent will transmit all records
pertaining to the Escrow Funds and will pay the 

  
 4 

 
Escrow Funds to the successor Escrow Agent, after making copies of such records as the retiring Escrow Agent deems advisable. If a successor Escrow Agent has not accepted such appointment by the
end of such 10 Business Day period or such successor escrow agent has not become so bound, Escrow Agent may, in its reasonable discretion, deliver the Escrow Funds to Trustee at the address provided herein or may apply to a court of competent
jurisdiction for the appointment of a successor escrow agent or for other appropriate relief. 
 9. Liability of Escrow
Agent. 
 (a) Escrow Agent will have no liability or obligation with respect to the Escrow Funds except for Escrow
Agent’s fraud, willful misconduct or gross negligence, and Escrow Agent shall not be required to expend or risk any of its own funds or otherwise incur any liability, financial or otherwise, in the performance of any of its duties hereunder.
Escrow Agent’s sole responsibility will be for the safekeeping, investment and disbursement of the Escrow Funds in accordance with the terms of this Agreement. Escrow Agent will have no implied duties or obligations and will not be charged with
knowledge or notice of any fact or circumstance not specifically set forth herein. Under no circumstances will the Escrow Agent be deemed to be a fiduciary to the Company or any other person under this Agreement. Escrow Agent may rely upon any
instrument, not only as to its due execution, validity and effectiveness, but also as to the truth and accuracy of any information contained therein, which Escrow Agent shall in good faith believe to be genuine, to have been signed or presented by
the person or parties purporting to sign the same and to conform to the provisions of this Agreement. Concurrently with the execution of this Agreement, the Company shall deliver to the Escrow Agent authorized signers’ forms in the form of
Exhibit C attached to this Escrow Agreement. In no event will Escrow Agent be liable for incidental, indirect, special, consequential or punitive damages. Escrow Agent will not be obligated to take any legal action or commence any proceeding in
connection with the Escrow Funds, any account in which Escrow Funds are deposited, this Agreement, or to appear in, prosecute or defend any such legal action or proceeding. Escrow Agent may consult legal counsel selected by it in the event of any
dispute or question as to the construction of any of the provisions hereof or of any other agreement or of its duties hereunder, or relating to any dispute involving any party hereto, and will incur no liability in acting in accordance with the
opinion or instruction of such counsel. Escrow Agent shall not be under any duty to give the Escrow Funds held by it hereunder any greater degree of care than it gives similar escrow property held by U.S. Bank National Association for similar escrow
accounts and shall not be required to invest any funds held hereunder except as directed in this Agreement. Uninvested funds held hereunder shall not earn or accrue interest. When Escrow Agent acts on any information, instructions, communications
(including, but not limited to, communications with respect to the delivery of securities or the wire transfer of funds) sent by telex, facsimile, e-mail or other form of electronic or data transmission, Escrow Agent, absent fraud, gross negligence
or willful misconduct, shall not be responsible or liable in the event such communication is not an authorized or authentic communication of the party purporting to have sent it, or is not in the form sent or intended to have been sent by the party
purporting to have sent it (whether due to fraud, distortion or otherwise). In the event of any ambiguity or uncertainty hereunder or in any notice, instruction or other communication received by Escrow Agent hereunder, Escrow Agent may, in its sole
discretion, refrain from taking any action other than to retain possession of the Escrow Funds, unless Escrow Agent receives written instructions, signed by the parties required to execute an amendment hereunder to the provisions under which such
ambiguity or uncertainty arises, which eliminates such ambiguity or uncertainty. 

  
 5 

 (b) Escrow Agent will not incur any liability, except for Escrow Agent’s fraud, willful
misconduct or gross negligence, for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of Escrow Agent (including but not limited to any act or provision of any
present or future law or regulation or governmental authority, any act of God or war, fire, terrorism, floods, strikes, or electrical outages related thereto or the unavailability of the Federal Reserve Bank wire or telex or other wire or
communication facility). Escrow Agent shall have no duty to verify or confirm any of the representations contained in the Release Certificate and shall have no responsibility therefor other than to confirm that it is substantially in
the form attached hereto. Escrow Agent shall be entitled to conclusively rely on the instructions of the Company or Trustee, as applicable. Trustee shall have no duties or responsibilities with respect to the Release Certificate or its
contents. 
 (c) Escrow Agent is authorized, in its sole discretion, to comply with orders issued or process entered by any
court with respect to the Escrow Funds, without determination by Escrow Agent of such court’s jurisdiction in the matter. If any portion of the Escrow Funds is at any time attached, garnished or levied upon under any court order, or in case the
payment, assignment, transfer, conveyance or delivery of any of the Escrow Funds shall be stayed or enjoined by any court order, or in case any order, judgment or decree shall be made or entered by any court affecting the Escrow Funds or any part
thereof, then and in any such event, Escrow Agent is authorized, in its sole discretion, to rely upon and comply with any such order, writ, judgment or decree which it is advised by legal counsel selected by it is binding upon it without the need
for appeal or other action; and if Escrow Agent complies with any such order, writ, judgment or decree, it will not be liable to any of the parties hereto or to any other person or entity by reason of such compliance even though such order, writ,
judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated. 
 10. Indemnification of Escrow
Agent. The Company will be liable for and will reimburse and indemnify Escrow Agent and its affiliates and their respective successors, assigns, directors, officers, managers and employees (the “Indemnitees”), and hold the Indemnitees
harmless from and against any and all claims, losses, liabilities, costs, damages or expenses (including reasonable attorneys’, agents’ and professional advisers’ fees and expenses) (collectively, “Losses”) arising from or
in connection with or related to this Agreement or being Escrow Agent hereunder (including but not limited to Losses incurred by Escrow Agent in connection with its successful defense, of any claim of gross negligence, willful misconduct or bad
faith on its part as determined by a court of competent jurisdiction in a final and non-appealable decision); provided, however, that nothing contained herein will require an Indemnitee to be indemnified for Losses caused by its gross negligence,
willful misconduct or bad faith as determined by a court of competent jurisdiction in a final and non-appealable decision. The provisions of this Section 10 will survive the termination of this Agreement or the earlier resignation or removal of
Escrow Agent.

expenses of Escrow Agent for its services hereunder as shall have been agreed to by the Company and Escrow Agent.

third-parties. This Agreement may be changed, waived, discharged or terminated only by a writing signed by the Issuer, Trustee and Escrow Agent; provided, that any amendment to Section 4 also will require the consent of holders of record of all
the then outstanding Notes. No delay or omission by any party in exercising any right with respect to this Agreement will operate as a waiver. A waiver on any one occasion will not be construed as a bar to, or waiver of, any right or remedy on any
future occasion.

20. Dealings. Escrow Agent and any stockholder, director, officer or employee of Escrow Agent may buy, sell, and deal in any of
the securities of the Company and become pecuniarily interested in any transaction in which the Company may be interested, and contract and lend money to the Company and otherwise act as fully and freely as though it were not Escrow Agent under this
Agreement. Nothing in this Agreement will preclude Escrow Agent from acting in any other capacity for the Company or for any other entity. 
 21. Security Advice Waiver. Trustee and the Company acknowledge that regulations of the Comptroller of the Currency may grant them the right to receive brokerage confirmations of the security
transactions as they occur. Trustee and the Company specifically waive such notification to the extent permitted by law and will receive periodic cash transaction statements that will detail all investment transactions. 

22. Patriot Act. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all
financial institutions to obtain, verify and record information that identifies each person who opens an account. For a non-individual person such as a business entity, a charity, a trust or other legal entity Escrow Agent will ask for documentation
to verify its formation and existence as a legal entity. Escrow Agent may also ask to see financial statements, licenses, identification and authorization documents from individuals claiming authority to represent the entity or other relevant
documentation and the parties to this Agreement agree to provide Escrow Agent with such information as it may request in accordance with this Section 22.

before the first Business Day (the “Cutoff Date for Waivable Voluntary Prepayments”) prior to the Voluntary Prepayment Date, (Y) on the Voluntary Prepayment Date, Company shall pay to Administrative Agent an amount equal to
that portion of the Waivable Voluntary Prepayment payable to those Lenders that have elected not to exercise such option (it being understood that any Lender which does not notify Company and Administrative Agent of its election to exercise such
option on or before the Cutoff Date for Waivable Voluntary Prepayments shall be deemed to have elected, as of the Cutoff Date for Waivable Voluntary Prepayments, not to exercise such option), which amount shall be applied to prepay the Term Loans of
such Lenders in accordance with this Section 2.4B(iv)(a), and (Z) Company shall be entitled to retain that portion of the Waivable Voluntary Prepayment otherwise payable to those Lenders that have elected to exercise such option (such
amount being a “Retained Voluntary Prepayment”) to be used for general corporate purposes; provided, that the terms of this sentence may, at the option of the Company, apply not only to the Waivable Voluntary Prepayment but
also to any subsequent voluntary prepayment to be made by the Company with (x) the Retained Prepayment resulting from a Waivable Voluntary Prepayment and/or (y) any Retained Prepayment resulting from a Waivable Mandatory Prepayment
relating to the proceeds of the 2012 Sale-Leaseback.”

the following provision: 
 “(b) all obligations of Company then owing to the Terminated Lender (other than
those (a) specifically described in clause (a) above in respect of which the assignment purchase price has been, or is concurrently being, paid, but including all amounts, if any, owing under Section 2.6D, (b) relating to any
Tranche of Loans and/or Commitments of the respective Terminated Lender which will remain outstanding after giving effect to the respective replacement or (c) to the extent such Terminated Lender is being replaced pursuant to this

  
 4 

 
Section 2.10 to effect a Repricing Transaction, the Prepayment Fee that would have otherwise been payable to such Terminated Lender if such Terminated Lender had consented to such Repricing
Transaction) shall be paid in full to such Terminated Lender concurrently with such replacement; 
 H. Section 7.2A of the
Credit Agreement is hereby amended by: 
  

	 	(a)	deleting the word “and” appearing at the end of clause (v) thereof; 

 

	 	(b)	adding a new clause (vi) immediately after clause (v) as follows: “Liens encumbering assets constituting “Additional Collateral” as defined in

 SECTION 2. Notices. 

(i) The Company hereby notifies the Administrative Agent that, pursuant to Sections 2.4B(iv)(a) and 2.4B(iv)(c) of the
Credit Agreement (as amended hereby), it elects to give each Lender holding an outstanding Term Loan the option to refuse such Lender’s Pro Rata Share of the Waivable Voluntary Prepayment and Waivable Mandatory Prepayment contemplated by
Sections 3(ii) and 3(iii) of this Amendment No. 2, respectively. 
 (ii) Notwithstanding anything to the
contrary contained in the Credit Agreement or in this Amendment No. 2, each Lender may exercise its option to refuse such Lender’s Pro Rata Share of the Waivable Voluntary Prepayment and Waivable Mandatory Prepayment contemplated by
clause (a) above by signing and delivering (including by way of facsimile or other electronic transmission) to the Administrative Agent the appropriate signature block regarding waivers in the signature page to this Amendment No. 2. Any
Lender which exercises its option to refuse its Pro Rata Share of any Waivable Voluntary Prepayment or Waivable Mandatory Prepayment by so noting on its signature page of this Amendment No. 2 shall be deemed to have waived any portion of
such prepayments, whether as part of the initial such offer to prepay or any subsequent offer by the Company to prepay the amounts referred to in Sections 3(ii) and 3(iii) of this Amendment No. 2 with amounts refused by other Lenders, the
effect being that the full amount of the prepayments required by Sections 3(ii) and 3(iii) of this Amendment No. 2 shall be made to Lenders which have not refused such prepayments by so noting on their signature page hereof (pro rata among such
Lenders) and no part of such prepayments shall be made to Lenders which have so refused such prepayments. 

(iii) The Company hereby notifies the Administrative Agent, pursuant to Section 2.4(B)(i) of the Credit Agreement (as
amended hereby), that it intends to prepay the Term Loans in an aggregate principal amount equal to $45,000,000, to be applied to the Scheduled Initial Term Loan Repayments in forward order, on November 6, 2012. The notice provided pursuant to
this clause (iii) is made contingent on the consummation of the 2012 Sale-Leaseback. In the event that the 2012 Sale-Leaseback is not consummated on November 5, 2012, the Company shall extend this notice so that the prepayment occurs
concurrently with the consummation of the 2012 Sale-Leaseback or rescind this notice in its entirety. 
 SECTION 3.
Conditions Precedent. This Amendment shall become effective on the date (the “Amendment No. 2 Effective Date”) when each of the following conditions shall have been satisfied: 

(i) each Loan Party, the Administrative Agent, and the Requisite Lenders shall have signed a counterpart hereof (whether
the same or different counterparts) and shall have delivered (including by way of facsimile or other electronic transmission) the same to the Administrative Agent; 

  
 6

amended hereby); provided that if any Lender declines such voluntary prepayment pursuant to Section 2.4B(iv)(a) of the Credit Agreement (as amended hereby) then the Company shall have re-offered such declined amounts as further voluntary
prepayments of the Term Loans until at least 95% of the prepayments contemplated by this clause (ii) and clause (iii) below shall have been applied to prepay the Term Loans; 

(iii) Company shall have consummated the 2012 Sale-Leaseback and shall have either (x) made a mandatory prepayment of
the Term Loans pursuant to Section 2.4B(iii)(b) of the Credit Agreement with the proceeds generated from the 2012 Sale-Leaseback in an amount at least equal to $30,000,000 or (y) made an offer to prepay at least $30,000,000 of the Term
Loans with the proceeds generated from the 2012 Sale-Leaseback pursuant to Section 2.4B(iv)(c) of the Credit Agreement; provided that if any Lender declines such mandatory prepayment pursuant to Section 2.4B(iv)(c) of the Credit
Agreement then the Company shall have re-offered such declined amounts as further voluntary prepayments of the Term Loans until at least 95% of the prepayments contemplated by this clause (iii) and clause (ii) above shall have been applied
to prepay the Term Loans; and 
 (iv) Company shall have paid to the Administrative Agent (x) for
distribution to each Lender which executes and delivers a counterpart of this Amendment by 12:00 p.m. (EDT) on October 31, 2012, an amendment fee equal to 0.50% of the sum of such Lender’s Revolving Loan Exposure plus such Lender’s
Term Loan Exposure, in each case, as of the Amendment No. 2 Effective Date (prior to giving effect to the prepayment of the Term Loans referred to in clauses (ii) and (iii) above) (it being understood that no fee shall be payable

the Administrative Agent in connection with this Amendment (including, without limitation, all reasonable legal fees and expenses of White & Case LLP, counsel to the Administrative Agent to the extent an invoice has been provided to Company
prior to the Amendment No. 2 Effective Date).

induce the Lenders to enter into this Amendment, Company hereby represents and warrants that (a) all of the representations and warranties set forth in Section 5 of the Credit Agreement and in each of the other Loan Documents are true and
correct in all material respects both immediately before and immediately after the Amendment No. 2 Effective Date, with the same effect as though such representations and warranties had been made on and as of the Amendment No. 2 Effective

modification or forbearance of, any term or condition of the Credit Agreement, any other Loan Document or any of the instruments or agreements referred to therein or a waiver of any Potential Event of Default or Event of Default under the Credit
Agreement, whether or not known to the Administrative Agent or any of the Lenders, (ii) to prejudice any right or remedy which the Administrative Agent or any of the Lenders may now have or have in the future under or in connection with the
Credit Agreement, any other Loan Document or any of the instruments or agreements referred to therein, or (iii) as an agreement by the Lenders to make any Loans or otherwise to extend additional credit at any time other than as expressly
