Board over the management of the Company, the power to direct the management, operation and policies of the Company, including making, financing and disposing of investments, shall be vested in the Advisor, which shall have the power by itself and
shall be authorized and empowered on behalf and in the name of the Company to carry out any and all of the objectives and purposes of the Company and to perform all acts and enter into and perform all contracts and other undertakings that it may in
its sole discretion deem necessary, advisable or incidental thereto to perform its obligations under this Agreement. 
 4.03
Approval by the Board. Notwithstanding the foregoing, the Advisor may not take any action on behalf of the Company (or its Subsidiaries) without the prior approval of the Board or duly authorized committees thereof if the Charter or Maryland General
Corporation Law require the prior approval of the Board (or if the governing documents or governing law applicable to any Subsidiary require the prior approval of the governing body of such Subsidiary). If the Board or a committee of the Board must
approve a proposed investment, financing or disposition or chooses to do so, the Advisor will deliver to the Board or committee, as applicable, all documents required by it to evaluate such investment, financing or disposition. 
 4.04 Modification or Revocation of Authority of Advisor. The Board may, at any time upon the giving of notice to the Advisor, modify or
revoke the authority or approvals set forth in Article 3 and this Article 4 hereof; provided, however, that such modification or revocation shall be effective upon receipt by the Advisor and shall not be applicable to investment transactions to
which the Advisor has committed the Company or its Subsidiaries prior to the date of receipt by the Advisor of such notification. 
 ARTICLE 5 
 BANK ACCOUNTS 
 The Advisor may establish and maintain one or more bank accounts in its own name for the account of the Company (and its Subsidiaries) or in the name of the Company (and its Subsidiaries) and may collect
and deposit into any such account or accounts, and disburse from any such account or accounts, any money on behalf of the Company and its Subsidiaries, under such terms and conditions as the Board (or the governing body of such Subsidiary) may
approve, provided that no funds shall be commingled with the funds of the Advisor. The Advisor shall from time to time render appropriate accountings of such collections and payments to the Board and the independent auditors of the Company.

  

 13 

 ARTICLE 6 
 RECORDS AND FINANCIAL STATEMENTS 
 The Advisor, in the
conduct of its responsibilities to the Company, shall maintain adequate and separate books and records for the Company’s and its Subsidiaries’ operations in accordance with GAAP, which shall be supported by sufficient documentation to
ascertain that such books and records are properly and accurately recorded. Such books and records shall be the property of the Company and its Subsidiaries and shall be available for inspection by the Board and by counsel, auditors and other
authorized agents of the Company, at any time or from time to time during normal business hours. Such books and records shall include all information necessary to calculate and audit the fees or reimbursements paid under this Agreement. The Advisor
shall utilize procedures to attempt to ensure such control over accounting and financial transactions as is reasonably required to protect the Company’s and its Subsidiaries’ assets from theft, error or fraudulent activity. All financial
statements that the Advisor delivers to the Company shall be prepared on an accrual basis in accordance with GAAP, except for special financial reports that by their nature require a deviation from GAAP. The Advisor shall liaise with the
Company’s officers and independent auditors and shall provide such officers and auditors with the reports and other information that the Company so requests. 
 ARTICLE 7 
 LIMITATION ON ACTIVITIES 
 Notwithstanding any provision in this Agreement to the contrary, the Advisor shall not take any action that, in its sole judgment made in
good faith, would (i) adversely affect the ability of the Company to qualify or continue to qualify as a REIT under the Code, (ii) subject the Company to regulation under the Investment Company Act of 1940, as amended, (iii) violate
any law, rule, regulation or statement of policy of any governmental body or agency having jurisdiction over the Company, its Shares or its other securities, (iv) require the Advisor to register as a broker-dealer with the SEC or any state,
(v) violate the Charter or Bylaws, or (vi) violate the governing documents of any Subsidiary of the Company. In the event an action that would violate (i) through (vi) of the preceding sentence but such action has been ordered by
the Board, the Advisor shall notify the Board of the Advisor’s judgment of the potential impact of such action and shall refrain from taking such action until it receives further clarification or instructions from the Board. In such event, the
Advisor shall have no liability for acting in accordance with the specific instructions of the Board so given.

 ARTICLE 8 
 FEES 
 8.01 Acquisition Fees. As compensation for the
investigation, selection, sourcing and acquisition or origination (by purchase, investment or exchange) of Properties, Loans and other Permitted Investments, the Company shall pay an Acquisition Fee to the Advisor for each such investment (whether
an acquisition or origination). With respect to the acquisition or origination of a Property, Loan or other Permitted Investment to be owned by the Company or a Subsidiary, the Acquisition Fee payable to the Advisor shall equal 2.0% of the sum of
the amount actually paid or allocated to fund the acquisition, origination, development, construction or improvement of the Property, Loan or other Permitted Investment, inclusive of the Acquisition Expenses associated with such Property, Loan or
other Permitted Investment and the amount of any debt associated with, or used to fund the investment in, such Property, Loan or other Permitted Investment. Acquisition Fees will also include any amounts incurred or reserved for capital expenditures
that will be used to provide funds for capital improvements and repairs applied to any real property investment acquired where the Company plans to add value. With respect to the acquisition or origination of a Property, Loan or other Permitted
Investment through any Joint Venture or any partnership in which the Company or the Partnership is, directly or indirectly, a partner and which is not deemed a Subsidiary, the Acquisition Fee payable to the Advisor shall equal 2.0% of the portion
that is attributable to the Company’s direct or indirect investment in such Joint Venture or partnership of the amount actually paid or allocated to fund the acquisition, origination, development, construction or improvement of the Property,
Loan or other Permitted Investment, inclusive of the Acquisition Expenses associated with such Property, Loan or other Permitted Investment, plus the amount of any debt associated with, or used to fund the investment in, such Property, Loan or other
Permitted Investment. Notwithstanding anything herein to the contrary, the payment of Acquisition Fees by the Company shall be subject to the limitations on Acquisition Fees contained in (and defined in) the Company’s Charter. The Advisor shall
submit an invoice to the Company following the closing or closings of each acquisition or origination, accompanied by a computation of the Acquisition Fee. Generally, the Acquisition Fee payable to the Advisor shall be paid at the closing of the
transaction upon receipt of the invoice by the Company. However, the Acquisition Fee may or may not be taken, in whole or in part, as to any year in the sole discretion of the Advisor. All or any portion of the Acquisition Fees not taken as to any
fiscal year shall be deferred without interest and may be paid in such other fiscal year as the Advisor shall determine. 
 8.02
Asset Management Fees. The Company shall pay the Advisor as compensation for the services described in Section 3.03 hereof a monthly fee (the “Asset Management Fee”) in an amount equal to one-twelfth of 1.0% of the higher of the Cost
of Investments or the Independently Appraised Value of Investments, as of the end of the preceding month. The Advisor shall submit a monthly invoice to the Company, accompanied by a computation of the Asset Management Fee for the applicable period.
Generally, the Asset Management Fee payable to the Advisor shall be paid on the last day of such month, or the first business day following the last day of such month. However,

  

 15 

 
the Asset Management Fee may or may not be taken, in whole or in part, as to any year in the sole discretion of the Advisor. All or any portion of the Asset Management Fees not taken as to any
fiscal year shall be deferred without interest and may be paid in such other fiscal year as the Advisor shall determine. 
 8.03
Disposition Fees. If the Advisor or any of its Affiliates provide a substantial amount of services (as determined by the Conflicts Committee) in connection with a Sale, the Advisor or such Affiliate shall receive a fee at the closing (the
“Disposition Fee”) equal to the lesser of (i) (A) one-half of the aggregate brokerage commission paid, including the brokerage commission payable pursuant to this clause 8.03(i)(A) or (B) if none is paid, the Competitive
Brokerage Commission or (ii) 2.75% of the Contract Sales Price; provided, however, that no Disposition Fee shall be payable to the Advisor for any Sale if such Sale involves the Company selling all or substantially all of its assets in one or
more transactions designed to effectuate a business combination transaction (as opposed to a Company liquidation, in which case the Disposition Fee would be payable if the Advisor or an Affiliate provides a substantial amount of services as provided
above). The Company will not pay a disposition fee upon the maturity, prepayment or workout of a loan or other real estate related debt investment; however, if the Company takes ownership of a property as a result of a workout or foreclosure of a
loan or the Company provides substantial assistance during the course of a workout, the Company will pay a disposition fee upon the sale of such property or disposition of such loan or other real estate related debt investment. The payment of any
Disposition Fees by the Company shall be subject to the limitations contained in the Company’s Charter. Any Disposition Fee payable under this Section 8.03 may be paid in addition to commissions paid to non-Affiliates, provided that the
total commissions (including such Disposition Fee) paid to all Persons by the Company for each Sale shall not exceed an amount equal to the lesser of (i) 6% of the aggregate Contract Sales Price of each Property, Loan or other Permitted
Investment or (ii) the Competitive Brokerage Commission for each Property, Loan or other Permitted Investment. The Advisor shall submit an invoice to the Company following the closing or closings of each disposition, accompanied by a
computation of the Disposition Fee. Generally, the Disposition Fee payable to the Advisor shall be paid at the closing of the transaction upon receipt of the invoice by the Company. However, the Disposition Fee may or may not be taken, in whole or
in part, as to any year in the sole discretion of the Advisor. All or any portion of the Disposition Fees not taken as to any fiscal year shall be deferred without interest and may be paid in such other fiscal year as the Advisor shall determine.

 8.04 Debt Financing Fees. In the event of any debt financing obtained by or for the Company or its Subsidiaries (and any
Joint Ventures that are not Subsidiaries but for which the Advisor provides substantial services in connection with obtaining such debt financing), the Company will pay to the Advisor a debt financing fee equal to 0.5% of the amount available under
the financing. The Debt Financing Fee includes the reimbursement of the specified cost incurred by the Advisor of engaging third parties to source debt financing, and nothing herein shall prevent the Advisor from entering fee-splitting arrangements
with third parties with respect to the Debt Financing Fee. All or any portion of the Debt Financing Fees not taken as to any fiscal year shall be deferred without interest and may be paid in such other fiscal year as the Advisor shall determine.

  

 16 

 
In no event will the Debt Financing Fee be paid more than once in respect of the same debt. For example, upon refinancing, the Advisor would only receive 0.5% of the incremental amount of
additional debt financing obtained in the refinancing. 
 8.05 Changes to Fee Structure. In the event of Listing, the Company
and the Advisor shall negotiate in good faith to establish a fee structure appropriate for a perpetual-life entity.

quarter and shall deliver such statement to the Company within 45 days after the end of each quarter. 
 (ii) The
Company shall not reimburse the Advisor to the extent such reimbursement would cause the total amount spent by the Company on Organization and Offering Expenses to exceed 15% of the Gross Proceeds raised as of the date of the reimbursement and

Expenses that in the four consecutive fiscal quarters then ended (the “Expense Year”) exceed (the “Excess Amount”) the greater of 2% of Average Invested Assets or 25% of Net Income (the “2%/25% Guidelines”) for such
year unless the Conflicts Committee determines that such excess was justified, based on unusual and nonrecurring factors that the Conflicts Committee deems sufficient. If the Conflicts Committee does not approve such excess as being so justified,
any Excess Amount paid to the Advisor during a fiscal quarter shall be repaid to the Company. If the Conflicts Committee determines such excess was justified, then, within 60 days after the end of any fiscal quarter of the Company for which total
reimbursed Operating Expenses for the Expense Year exceed the 2%/25% Guidelines, the Advisor, at the direction of the Conflicts Committee, shall cause such fact to be disclosed to the Stockholders in writing (or the Company shall disclose such fact
to the Stockholders in the next quarterly report of the Company or by filing a Current Report on Form 8-K with the SEC within 60 days of such quarter end), together with an explanation of the factors the Conflicts Committee considered in determining

applied on a consistent basis. 
 ARTICLE 10 
 VOTING AGREEMENT 
 The Advisor agrees that, with respect to any Shares now
or hereinafter owned by it, the Advisor will not vote or consent on matters submitted to the stockholders of the Company regarding (i) the removal of the Advisor or any Affiliate of the Advisor or (ii) any transaction between the Company

 20 

 ARTICLE 11 
 RELATIONSHIP OF ADVISOR AND COMPANY; 
 OTHER
ACTIVITIES OF THE ADVISOR 
 11.01 Relationship. The Company and the Advisor are not partners or joint venturers with each
other, and nothing in this Agreement shall be construed to make them such partners or joint venturers. Nothing herein contained shall prevent the Advisor from engaging in other activities, including, without limitation, the rendering of advice to
other Persons (including other REITs) and the management of other programs advised, sponsored or organized by the Advisor or its Affiliates. Nor shall this Agreement limit or restrict the right of any manager, director, officer, employee or
equityholder of the Advisor or its Affiliates to engage in any other business or to render services of any kind to any other Person. The Advisor may, with respect to any investment in which the Company is a participant, also render advice and
service to each and every other participant therein. The Advisor shall promptly disclose to the Board the existence of any condition or circumstance, existing or anticipated, of which it has knowledge, that creates or could create a conflict of
interest between the Advisor’s obligations to the Company and its obligations to or its interest in any other Person. 
 11.02 Time Commitment. The Advisor shall, and shall cause its Affiliates and their respective employees, officers and agents to, devote to the Company such time as shall be reasonably necessary to conduct the business and affairs of the
Company in an appropriate manner consistent with the terms of this Agreement. The Company acknowledges that the Advisor and its Affiliates and their respective employees, officers and agents may also engage in activities unrelated to the Company and
may provide services to Persons other than the Company or any of its Affiliates. 
 11.03 Investment Opportunities and
Allocation. The Advisor shall be required to use commercially reasonable efforts to present a continuing and suitable investment program to the Company that is consistent with the investment policies and objectives of the Company, but neither the
Advisor nor any Affiliate of the Advisor shall be obligated generally to present any particular investment opportunity to the Company even if the opportunity is of character that, if presented to the Company, could be taken by the Company. In the
event an investment opportunity is located, the allocation procedure set forth under the captions “Conflicts of Interest – Certain Conflict Resolution Measures – Resolution of Potential Conflicts of Interest in Allocation of
Investment Opportunities” and “Conflicts of Interest – Certain Conflict Resolution Measures – Allocation of Investment Opportunities” in the Registration Statement and private placement memorandum of the Company shall govern
the allocation of the opportunity among the Company and Affiliates of the Advisor. 
  

 21 

 ARTICLE 12 
 THE RESOURCE REAL ESTATE OPPORTUNITY NAME 
 The
Advisor and its Affiliates have a proprietary interest in the name “RESOURCE REAL ESTATE OPPORTUNITY.” The Advisor hereby grants to the Company a non-transferable, non-assignable, non-exclusive royalty-free right and license to use the
name “RESOURCE REAL ESTATE OPPORTUNITY” during the term of this Agreement. Accordingly, and in recognition of this right, if at any time the Company ceases to retain the Advisor or one of its Affiliates to perform advisory services for the
Company, the Company will, promptly after receipt of written request from the Advisor, cease to conduct business under or use the name “RESOURCE REAL ESTATE OPPORTUNITY” or any derivative thereof and the Company shall change its name and
the names of any of its subsidiaries to a name that does not contain the name “RESOURCE REAL ESTATE OPPORTUNITY” or any other word or words that might, in the reasonable discretion of the Advisor, be susceptible of indication of some form
of relationship between the Company and the Advisor or any its Affiliates. At such time, the Company will also make any changes to any trademarks, servicemarks or other marks necessary to remove any references to the word “RESOURCE REAL ESTATE
OPPORTUNITY.” Consistent with the foregoing, it is specifically recognized that the Advisor or one or more of its Affiliates has in the past and may in the future organize, sponsor or otherwise permit to exist other investment vehicles
(including vehicles for investment in real estate) and financial and service organizations having “RESOURCE REAL ESTATE OPPORTUNITY” as a part of their name, all without the need for any consent (and without the right to object thereto) by
the Company. 
 ARTICLE 13 
 TERM AND TERMINATION OF THE AGREEMENT 
 13.01 Term. This Agreement shall
have an initial term of one year from the date hereof and may be renewed for an unlimited number of successive one-year terms upon mutual consent of the parties. The Company (acting through the Conflicts Committee) will evaluate the performance of
the Advisor annually before renewing this Agreement, and each such renewal shall be for a term of no more than one year. Any such renewal must be approved by the Conflicts Committee. 
 13.02 Termination by Either Party. This Agreement may be terminated upon 60 days written notice without cause or penalty by either the
Company (acting through the Conflicts Committee) or the Advisor. The provisions of Articles 1, 10, 12, 13, 15 and 17 shall survive termination of this Agreement. 
 13.03 Payments on Termination . Payments to the Advisor pursuant to this Section 13.03 shall be subject to the 2%/25% Guidelines to the extent applicable. After the Termination Date, the Advisor
shall not be entitled to compensation for further services hereunder except it shall be entitled to receive from the Company within 30 days after the effective date of such termination all unpaid reimbursements of expenses and all earned but unpaid
fees payable to the Advisor prior to termination of this Agreement. 
  

 22 

 13.04 Duties of Advisor Upon Termination. The Advisor shall promptly upon termination:

accrued compensation and reimbursement for its expenses to which it is then entitled;

Board a full accounting, including a statement showing all payments collected by it and a statement of all money held by it, covering the period following the date of the last accounting furnished to the Board; 
 (iii) deliver to the Board all assets and documents of the Company then in the custody of the Advisor; and 
 (iv) cooperate with the Company to provide an orderly transition of advisory functions. 
 ARTICLE 14 
 ASSIGNMENT 
 This Agreement may be assigned by the Advisor to an Affiliate with the consent of the Conflicts
Committee. The Advisor may assign any rights to receive fees or other payments under this Agreement without obtaining the approval of the Board. This Agreement shall not be assigned by the Company without the consent of the Advisor, except in the
case of an assignment by the Company to a corporation or other organization that is a successor to all of the assets, rights and obligations of the Company, in which case such successor organization shall be bound hereunder and by the terms of said
assignment in the same manner as the Company is bound by this Agreement. 
 ARTICLE 15 
 INDEMNIFICATION AND LIMITATION OF LIABILITY 
 15.01 Indemnification. Except as prohibited by the restrictions provided in this Section 15.01, Section 15.02 and Section 15.03, the Company shall indemnify, defend and hold harmless the
Advisor and its Affiliates, including their respective officers, directors, equity holders, partners and employees, from all liability, claims, damages or losses arising in the performance of their duties hereunder, and related expenses, including
reasonable attorneys’ fees, to the extent such liability, claims, damages or losses and related expenses are not fully reimbursed by insurance. Any indemnification of the Advisor may be made only out of the net assets of the Company and not
from Stockholders. 
  

 23 

 Notwithstanding the foregoing, the Company shall not indemnify the Advisors or its
Affiliates for any loss, liability or expense arising from or out of an alleged violation of federal or state securities laws by such party unless one or more of the following conditions are met: (i) there has been a successful adjudication on
the merits of each count involving alleged material securities law violations as to the particular indemnitee; (ii) such claims have been dismissed with prejudice on the merits by a court of competent jurisdiction as to the particular
indemnitee; or (iii) a court of competent jurisdiction approves a settlement of the claims against a particular indemnitee and finds that indemnification of the settlement and the related costs should be made, and the court considering the
request for indemnification has been advised of the position of the Securities and Exchange Commission and of the published position of any state securities regulatory authority in which securities of the Company were offered or sold as to
indemnification for violations of securities laws. 
 15.02 Limitation on Indemnification. Notwithstanding the foregoing, the
Company shall not provide for indemnification of the Advisor or its Affiliates for any liability or loss suffered by any of them, nor shall any of them be held harmless for any loss or liability suffered by the Company, unless all of the following
conditions are met: 
 (i) The Advisor or its Affiliates have determined, in good faith, that the course of
conduct that caused the loss or liability was in the best interests of the Company. 
 (ii) The Advisor or its
Affiliates were acting on behalf of or performing services for the Company. 
 (iii) Such liability or loss was
not the result of negligence or misconduct by the Advisor or its Affiliates. 
 15.03 Limitation on Payment of Expenses. The
Company shall pay or reimburse reasonable legal expenses and other costs incurred by the Advisors or its Affiliates in advance of the final disposition of a proceeding only if (in addition to the procedures required by the Maryland General
Corporation Law, as amended from time to time) all of the following are satisfied: (a) the proceeding relates to acts or omissions with respect to the performance of duties or services on behalf of the Company, (b) the legal proceeding was
initiated by a third party who is not a stockholder or, if by a stockholder acting in his or her capacity as such, a court of competent jurisdiction approves such advancement and (c) the Advisor or its Affiliates undertake to repay the amount
paid or reimbursed by the Company, together with the applicable legal rate of interest thereon, if it is ultimately determined that the particular indemnitee is not entitled to indemnification. 
  

 24

Section 1.4. Calculations and Determinations. All calculations under the Loan Documents of
interest chargeable with respect to Eurodollar Loans and of fees shall be made on the basis of
actual days elapsed (including the first day but excluding the last) and a year of 360 days. All
other calculations of interest made under the Loan Documents shall be made on the basis of actual
days elapsed (including the first day but excluding the last) and a year of 365 or 366 days, as
appropriate. Each determination by a Lender Party of amounts to be paid under Article III or any
other matters which are to be determined hereunder by a Lender Party (such as any Eurodollar Rate,

Document. All indemnification and release provisions of this Agreement shall be construed broadly
(and not narrowly) in favor of the Persons receiving indemnification or being released.

	 	 	 
	ARTICLE II — The Loans and Letters of Credit

	 

	Section 2.1.

	 	Commitments to Lend; Notes.
	
 
	 	 

(a) Loans. Subject to the terms and conditions hereof, each Lender agrees to make
loans to Borrower (herein called such Lender’s “Loans”) upon Borrower’s request from time
to time during the Commitment Period, provided that (a) subject to Sections 3.3, 3.4 and 3.6,
Loans of the same Type shall be made by Lenders in accordance with their respective Percentage
Shares and as part of the same Borrowing, and (b) after giving effect to such Loans, (i) the
Facility Usage does not exceed the Aggregate Commitment, and (ii) the Facility Usage does not
exceed the lesser of the Borrowing Base or the Aggregate Commitment then in effect. The
obligation of Borrower to repay to each Lender the aggregate amount of all Loans made by such
Lender, together with interest accruing in connection therewith, shall be evidenced by a single
promissory note (herein called such Lender’s “Note”) made by Borrower payable to the order
of such Lender in the form of Exhibit A with appropriate insertions. The amount of principal
owing on any Lender’s Note at any given time shall be the aggregate amount of all Loans
theretofore made by such Lender minus all payments of principal theretofore received by such
Lender on such Note. Interest on each Note shall accrue and be due and payable as provided
herein. Each Note shall be due and payable as provided herein, and shall be due and payable in
full on the Maturity Date. Subject to the terms and conditions hereof, Borrower may borrow,
repay, and reborrow Loans hereunder.

(b) Amount and Number of Borrowings. The aggregate amount of all Loans (other than
Loans made pursuant to Section 2.12(b)) in any Borrowing must be greater than or equal to $5,000
or any higher integral multiple of $5,000 or must equal the remaining availability under the
Borrowing Base. Borrower may have no more than five Borrowings of Eurodollar Loans outstanding at
any time.

Section 2.2. Requests for New Loans. Borrower must give to Administrative Agent written or
electronic notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing
of new Loans to be advanced by Lenders. Each such notice constitutes a “Borrowing Notice”
hereunder and must:

(a) specify (i) the aggregate amount of any such Borrowing of new Base Rate Loans and the
date on which such Base Rate Loans are to be advanced, or (ii) the aggregate amount of any such
Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced
(which shall be the first day of the Interest Period which is to apply thereto), and the length of
the applicable Interest Period; and

(b) be received by Administrative Agent not later than 10:00 a.m., Denver, Colorado time, on
(i) the day on which any such Base Rate Loans are to be made, or (ii) the third Business Day
preceding the day on which any such Eurodollar Loans are to be made.

Each such written request or confirmation must be made in the form and substance of the
“Borrowing Notice” attached hereto as Exhibit B, duly completed. Each such telephonic request
shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the
matters which are required to be set out in such written confirmation. Upon receipt of any such
Borrowing Notice, Administrative Agent shall give each Lender prompt notice of the terms thereof.
If all conditions precedent to such new Loans have been met, each Lender will on the date requested
promptly remit to Administrative Agent at Administrative Agent’s office in Denver, Colorado the
amount of such Lender’s new Loan in immediately available funds, and upon receipt of such funds,
unless to its actual knowledge any conditions precedent to such Loans have been neither met nor
waived as provided herein, Administrative Agent shall promptly make such Loans available to
Borrower. Unless Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing that such Lender will not make available to Administrative Agent
such Lender’s share of such Borrowing, Administrative Agent may assume that such Lender has made
such share available on such date in accordance with this Section 2.2 and may, in reliance upon
such assumption, make available to Borrower a corresponding amount. In such event, if a Lender has
not in fact made its share of the applicable Borrowing available to Administrative Agent, then the
applicable Lender and Borrower severally agree to pay to Administrative Agent forthwith on demand
such corresponding amount with interest thereon, for each day from and including the date such
amount is made available to Borrower to but excluding the date of payment to Administrative Agent,
at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate
and a rate determined by Administrative Agent in accordance with banking industry rules on
interbank compensation and (ii) in the case of a payment to be made by Borrower, the interest rate
applicable to Base Rate Loans. If Borrower and such Lender shall pay such interest to
Administrative Agent for the same or an overlapping period, Administrative Agent shall promptly
remit to Borrower the amount of such interest paid by Borrower for such period. If such Lender
pays its share of the applicable Borrowing to Administrative Agent, then the amount so paid shall
constitute such Lender’s Loan included in such Borrowing. Any payment by Borrower shall be without
prejudice to any claim Borrower may have against a Lender that shall have failed to make such
payment to Administrative Agent.

Section 2.3. Continuations and Conversions of Existing Loans. Borrower may make the
following elections with respect to Loans already outstanding: to convert Base Rate Loans to
Eurodollar Loans, to convert Eurodollar Loans to Base Rate Loans on the last day of the Interest
Period applicable thereto, and to continue Eurodollar Loans beyond the expiration of such Interest
Period by designating a new Interest Period to take effect at the time of such expiration. In
making such elections, Borrower may combine existing Loans made pursuant to separate Borrowings
into one new Borrowing or divide existing Loans made pursuant to one Borrowing into separate new
Borrowings, provided that Borrower may have no more than five Borrowings of Eurodollar Loans
outstanding at any time. To make any such election, Borrower must give to Administrative Agent
written notice (or telephonic notice promptly confirmed in writing) of any such Conversion or
Continuation of existing Loans, with a separate notice given for each new Borrowing. Each such
notice constitutes a “Continuation/Conversion Notice” hereunder and must:

(a) specify the existing Loans which are to be Continued or Converted;

(b) specify (i) the aggregate amount of any Borrowing of Base Rate Loans into which such
existing Loans are to be continued or converted and the date on which such Continuation or
Conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into
which such existing Loans are to be continued or converted, the date on which such Continuation or
Conversion is to occur (which shall be the first day of the Interest Period which is to apply to
such Eurodollar Loans), and the length of the applicable Interest Period; and

(c) be received by Administrative Agent not later than 10:00 a.m., Denver, Colorado time, on
(i) the day on which any such Continuation or Conversion to Base Rate Loans is to occur, or (ii)
the third Business Day preceding the day on which any such Continuation or Conversion to
Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance of the
“Continuation/Conversion Notice” attached hereto as Exhibit C, duly completed. Each such
telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by
Borrower as to the matters which are required to be set out in such written confirmation. Upon
receipt of any such Continuation/Conversion Notice, Administrative Agent shall give each Lender
prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and
binding on Borrower. During the continuance of any Default, Borrower may not make any election to
convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. If
(due to the existence of a Default or for any other reason) Borrower fails to timely and properly
give any Continuation/Conversion Notice with respect to a Borrowing of existing Eurodollar Loans at
least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans
shall automatically be converted into Base Rate Loans at the end of such Interest Period. No new
funds shall be repaid by Borrower or advanced by any Lender in connection with any Continuation or
Conversion of existing Loans pursuant to this section, and no such Continuation or Conversion shall
be deemed to be a new advance of funds for any purpose; such Continuations and Conversions merely
constitute a change in the interest rate applicable to already outstanding Loans.

Section 2.4. Use of Proceeds. Borrower shall use all Loans to refinance existing
indebtedness, to finance capital expenditures, to refinance Matured LC Obligations, and provide
working capital for its operations and for other general business purposes, including Core
Acquisitions and Investments. Borrower shall use all Letters of Credit for its general corporate
purposes. In no event shall the funds from any Loan or any Letter of Credit be used directly or
indirectly by any Person for personal, family, household or agricultural purposes or for the
purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any
“margin stock” (as such term is defined in Regulation U promulgated by the Board of Governors of
the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of
purchasing or carrying any such margin stock. Borrower represents and warrants that Borrower is
not engaged principally, or as one of Borrower’s important activities, in the business of extending
credit to others for the purpose of purchasing or carrying such margin stock.

Section 2.5. Interest Rates and Fees; Payment Dates.

(a) Interest Rates. Subject to subsection (b) below, (i) each Base Rate Loan shall
bear interest on each day outstanding at the Adjusted Base Rate in effect on such day and
(ii) each Eurodollar Loan shall bear interest on each day during the related Interest Period at
the related Adjusted Eurodollar Rate in effect on such day.

(b) Default Rate. If an Event of Default shall have occurred and be continuing under
Section 8.1(a), (b), (j)(i), (j)(ii), or (j)(iii), all outstanding Loans shall bear interest at
the applicable Default Rate. In addition, if an Event of Default shall have occurred and be
continuing (other than under Section 8.1(a), (b), (j)(i), (j)(ii), or (j)(iii)), Required Lenders
may, by notice to Borrower, elect to have the outstanding Loans bear interest at the applicable
Default Rate, whereupon such Loans shall bear interest at the applicable Default Rate until the
earlier of (i) the first date thereafter upon which there shall be no Event of Default continuing
and (ii) the date upon which Required Lenders shall have rescinded such notice.

(c) Commitment Fees. In consideration of each Lender’s commitment to make Loans,
Borrower will pay to Administrative Agent for the account of each Lender a commitment fee
determined on a daily basis by applying the Commitment Fee Rate to such Lender’s Percentage Share
of the Unused Borrowing Base determined at the end of each day during the Commitment Period. This
commitment fee shall be due and payable in arrears on the last day of each Fiscal Quarter and at
the end of the Commitment Period. Notwithstanding the foregoing, no Impacted Lender shall be paid
a commitment fee hereunder.

(d) Payment Dates. On each Interest Payment Date relating to Base Rate Loans,
Borrower shall pay to the Lenders all unpaid interest which has accrued on the Base Rate Loans to
but not including such Interest Payment Date. On each Interest Payment Date relating to a
Eurodollar Loan, Borrower shall pay to Lenders all unpaid interest which has accrued on such
Eurodollar Loan to but not including such Interest Payment Date.

(e) Borrowing Base Increase Fee. Borrower will pay to Administrative Agent for the
account of each Lender on each Determination Date on which the Borrowing Base is increased, a
borrowing base increase fee in the amount determined by Administrative Agent to be the market
standard for similar borrowers. Such fee shall be due and payable on the effective date of such
Borrowing Base increase and allocated to each Lender based upon such Lender’s Percentage Share of
such increase.

Section 2.6. Optional Prepayments. Borrower may, (a) upon one Business Days’ notice to
Administrative Agent with respect to any Base Rate Loan and (b) upon three Business Days’ notice to
Administrative Agent with respect to any Eurodollar Loan, from time to time and without premium or
penalty prepay the Loans, in whole or in part, provided (i) that the aggregate amounts of all
partial prepayments of principal on the Loans equals $5,000 or any higher integral multiple of
$5,000, (ii) that Borrower does not make any prepayments which would reduce the unpaid principal
balance of any Loan to less than $10,000 without first either (1) terminating this Agreement or (2)
providing assurance satisfactory to Administrative Agent in its discretion that Lenders’ legal
rights under the Loan Documents are in no way adversely affected by such reduction, and (iii) that
if Borrower prepays any Eurodollar Loan on any day other than the last day of the Interest Period
applicable thereto, it shall pay to Lenders any amounts due under Section 3.5. Each prepayment of
principal under this section shall be accompanied by all interest then accrued and unpaid on the
principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in
addition to, and not in lieu of, all payments otherwise required to be paid under the Loan
Documents at the time of such prepayment.

Section 2.7. Mandatory Prepayments

(a) If at any time the Facility Usage exceeds the Maximum Credit Amount (whether due to a
reduction in the Maximum Credit Amount in accordance with this Agreement, or otherwise), Borrower
shall immediately upon demand prepay the principal of the Loans (and after all Loans are repaid in
full, provide LC Collateral in accordance with Section 2.16(a)) in an amount at least equal to
such excess.

(b) If at any time the Facility Usage is less than the Maximum Credit Amount but in excess of
the Borrowing Base (such excess being herein called a “Borrowing Base Deficiency”),
Borrower shall, within five Business Days after Administrative Agent gives notice of such fact to
Borrower, either:

(i) give notice to Administrative Agent electing to prepay the principal of the Loans
(and, if the Facility Usage exceeds the Borrowing Base after all Loans are repaid in full,
provide LC Collateral in accordance with Section 2.16(a)) in an aggregate amount sufficient
to eliminate such Borrowing Base Deficiency (or, if the Facility Usage exceeds the Borrowing
Base after the Loans have been paid in full, pay to LC Issuer LC Collateral as required
under Section 2.16(a)), such prepayment to be made in full on or before the thirtieth day
after such notice by Administrative Agent to Borrower of such Borrowing Base Deficiency; or

(ii) give notice to Administrative Agent electing to prepay the principal of the Loans
(and after all Loans are repaid in full, provide LC Collateral in accordance with Section
2.16(a)) in up to six monthly installments in an aggregate amount at least equal to such
Borrowing Base Deficiency, with each such installment equal to or in excess of one-sixth of
such Borrowing Base Deficiency, and with the first such installment to be paid within thirty
days after the giving of such notice by Administrative Agent to Borrower of such Borrowing
Base Deficiency and the subsequent installments to be due and payable at one month intervals
thereafter until such Borrowing Base Deficiency has been eliminated; provided, however,
Borrower shall have demonstrated to the satisfaction of Administrative Agent on or before
the date of the first such payment that Borrower has sufficient available monthly cash from
its Projected Oil and Gas Production to make such payments; or

(iii) give notice to Administrative Agent that Borrower desires to provide (or cause to
be provided by other Restricted Persons) Administrative Agent with deeds of trust,
mortgages, chattel mortgages, security agreements, financing statements and other security
documents in form and substance similar to the Security Documents previously delivered to
Administrative Agent (with any changes required to conform to changes in Law or changes in
the type of collateral covered thereby), and otherwise satisfactory to Administrative Agent,
granting, confirming, and perfecting first and prior liens or security interests in
collateral acceptable to all Lenders subject to no liens other than Permitted Liens, to the
extent needed to allow Required Lenders to increase the Borrowing Base (as they in their
reasonable discretion deem consistent with prudent oil and gas banking industry lending
standards at the time) to an amount which eliminates such Borrowing Base Deficiency, and
such Security Documents shall be executed and delivered to Administrative Agent within
thirty days after Administrative Agent confirms to Borrower what collateral shall be
required. If, prior to any such specification by Administrative Agent, Required Lenders
determine that the giving of such Security Documents will not serve to eliminate such
Borrowing Base Deficiency, then, within five Business Days after receiving notice of such
determination from Administrative Agent, Borrower will elect to make, and thereafter make,
the prepayments specified in either of the preceding subsections (i) or (ii) of this
subsection (b).

Section 2.8. Initial Borrowing Base. During the period from the date hereof to the first
Determination Date the Borrowing Base shall be $45,000,000.

Section 2.9. Subsequent Determinations of Borrowing Base.

(a) By March 1 and September 1 of each year beginning March 1, 2010, Borrower shall furnish
to each Lender all information, reports and data which Administrative Agent has then requested
concerning Restricted Persons’ businesses and properties (including their Oil and Gas Properties
and interests and the reserves and production relating thereto), together with, as applicable, the
Engineering Report as of January 1 of such year described in Section 6.2(e) or as of July 1 of
such year described in Section 6.2(f). By June 15 and December 15 of each year, Administrative
Agent shall determine the amount of a proposed Borrowing Base; and Administrative Agent shall then
deliver to each Lender such proposed Borrowing Base. Within fifteen days after the Lenders’
receipt of such proposed Borrowing Base, or as promptly thereafter as practicable, Required
Lenders shall agree on an amount for the Borrowing Base (provided that all Lenders must agree on
any increase in the Borrowing Base), which need not be equal to such proposed Borrowing Base.
Required Lenders shall determine the amount of the Borrowing Base based upon the loan collateral
value which they in their discretion assign to the discounted net present value of the various Oil
and Gas Properties of Restricted Persons included in the Collateral at the time in question and
based upon such other credit factors (including without limitation the assets, liabilities, cash
flow, hedged and unhedged exposure to price, foreign exchange rate, and interest rate changes,
business, properties, prospects, management and ownership of Restricted Persons) as they in their
discretion deem significant. If Required Lenders (or all Lenders in the case of an increase in
the Borrowing Base) have not approved the Borrowing Base within the fifteen day period after their
receipt of such proposed Borrowing Base, Administrative Agent shall poll Lenders to ascertain the
highest Borrowing Base then acceptable to a number of Lenders sufficient to constitute Required
Lenders (or all Lenders in the case of an increase in the Borrowing Base) and such amount shall
then become the Borrowing Base. Administrative Agent shall by notice to Borrower designate such
amount as the new Borrowing Base available to Borrower hereunder, which designation shall take
effect immediately on the date such notice is sent (herein called a “Determination Date”)
and shall remain in effect until but not including the next date as of which the Borrowing Base is
redetermined. It is expressly understood that Lenders and Administrative Agent have no
obligation to agree upon or designate the Borrowing Base at any particular amount, whether in
relation to the MAXIMUM CREDIT AMOUNT or otherwise, and that Lenders’ commitments to advance funds
hereunder is determined by reference to the Borrowing Base from time to time in effect, which
Borrowing Base shall be used for calculating commitment fees under Section 2.5 and, to the extent
permitted by Law and regulatory authorities, for the purposes of capital adequacy determination
and reimbursements under Section 3.2.

(b) If Borrower does not furnish all such information, reports and data by the date specified
in the first sentence of subsection (a) of this section, Administrative Agent may nonetheless
determine the Borrowing Base at any amount that Required Lenders determine and may redetermine the
Borrowing Base from time to time thereafter (provided that all Lenders must agree to any increase
in the Borrowing Base) until each Lender receives all such information, reports and data,
whereupon Required Lenders (or all Lenders, as applicable) shall designate a new Borrowing Base as
described above.

In addition to the redeterminations of the Borrowing Base pursuant to subsections (a) and (b) of
this section, Borrower and Administrative Agent (or Administrative Agent at the request of Required
Lenders) may each request additional determinations (“Special Determinations”) of the
Borrowing Base from time to time; provided, that no such Person may request more than one (1)
Special Determination between Scheduled Determinations. In the event Administrative Agent (or
Administrative Agent at the request of Required Lenders) requests such a Special Determination,
Administrative Agent shall promptly deliver notice of such request to Borrower and Borrower shall,
within thirty (30) days following the date of such request, deliver to Lenders an Engineering
Report prepared by Staff Engineers as of the last day of the calendar month preceding the date of
such request (or prepared by Independent Engineers) and such other information which Administrative
Agent shall have requested. In the event Borrower requests a Special Determination, Borrower shall
deliver written notice of such request to Lenders which shall include (i) an Engineering Report
prepared by Staff Engineers as of a date not more than thirty (30) days prior to the date of such
request (or, in the case of a request made on the 31st day of any calendar month,
thirty-one (31) days), (ii) the amount of the Borrowing Base requested by Borrower and to become
effective on the Determination Date applicable to such Special Determination and (iii) such other
information which Administrative Agent shall have requested. Upon receipt of such Engineering
Report and other information, Administrative Agent shall, subject to approval of Required Lenders,
or all Lenders in the event of a proposed increase in the Borrowing Base, redetermine the Borrowing
Base in accordance with the procedure set forth in subsection (a) of this section, which Borrowing
Base shall become effective on the Determination Date (or as soon thereafter as Administrative
Agent and Required Lenders, or all Lenders in the event of a proposed increase in the Borrowing
Base, approve such Borrowing Base and provide notice thereof to Borrower).

Section 2.10. Letters of Credit. Subject to the terms and conditions hereof, Borrower may
at any time during the Commitment Period request LC Issuer to issue, increase the amount of or
otherwise amend or extend, one or more Letters of Credit, provided that, after taking such Letter
of Credit into account:

(a) the Facility Usage does not exceed the Borrowing Base at such time;

(b) the aggregate amount of LC Obligations at such time does not exceed the LC Sublimit;

(c) the expiration date of such Letter of Credit (as extended, if applicable) is prior to the
Letter of Credit Termination Date;

(d) such Letter of Credit is to be used for general business purposes of Borrower a
Restricted Person;

(e) such Letter of Credit is not directly or indirectly used to assure payment of or
otherwise support any Indebtedness of any Person other than Indebtedness of any Restricted Person;

(f) the issuance of such Letter of Credit will be in compliance with all applicable
governmental restrictions, policies, and guidelines and will not subject LC Issuer to any cost
which is not reimbursable under Article III;

(g) the form and terms of such Letter of Credit are acceptable to LC Issuer in its sole and
absolute discretion;

(h) no Lender is at such time an Impacted Lender hereunder, unless LC Issuer has entered into
arrangements reasonably satisfactory to LC Issuer, provided that Borrower and LC Issuer agree
that the delivery of cash collateral to LC Issuer shall constitute satisfactory arrangements,
with Borrower or such Lender to eliminate LC Issuer’s risk with respect to such Lender; and

(i) all other conditions in this Agreement to the issuance of such Letter of Credit have been
satisfied.

LC Issuer will honor any such request if the foregoing conditions (a) through (h) (the “LC
Conditions”) have been met as of the date of issuance of such Letter of Credit. LC Issuer may
choose to honor any such request for any other Letter of Credit but has no obligation to do so and
may refuse to issue any other requested Letter of Credit for any reason which LC Issuer in its sole
discretion deems relevant.

Borrower may also at any time during the Commitment Period request that LC Issuer extend the
expiration date of an existing Letter of Credit or modify an existing Letter of Credit (other than
an increase or extension) and LC Issuer will honor such request if the LC Conditions set forth in
subsection (c) of this Section 2.11 are met and no Default exists at the time of such request;
provided that in the case of any such modification (other than an increase or extension), LC Issuer
shall have approved such modification.

Section 2.11. Requesting Letters of Credit.

(a) Borrower must make written application for any Letter of Credit or amendment or extension
of any Letter of Credit at least five Business Days (or such shorter period as LC Issuer may in
its discretion from time to time agree) before the date on which Borrower desires for LC Issuer to
issue such Letter of Credit. By making any such written application, unless otherwise expressly
stated therein, Borrower shall be deemed to have represented and warranted that the LC Conditions
described in Section 2.11 will be met as of the date of issuance of such Letter of Credit. Each
such written application for a Letter of Credit must be made in writing in the form customarily
used by LC Issuer, the terms and provisions of which are hereby incorporated herein by reference
(or in such other form as may mutually be agreed upon by LC Issuer and Borrower).

(b) If the Borrower so requests in any applicable L/C Application, the L/C Issuer may, in its
sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension
provisions (each, an “Auto-Extension Letter of Credit”); provided that any such
Auto-Extension Letter of Credit must permit the L/C Issuer to prevent any such extension at least
once in each twelve-month period (commencing with the date of issuance of such Letter of Credit)
by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension
Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of
Credit is issued. Unless otherwise directed by the L/C Issuer, the Borrower shall not be required
to make a specific request to the L/C Issuer for any such extension. Once an Auto-Extension
Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not
require) the L/C Issuer to permit the extension of such Letter of Credit at any time to an expiry
date not later than the Letter of Credit Expiration Date; provided, however, that
the L/C Issuer shall not permit any such extension if (A) the L/C Issuer has determined that it
would not be permitted, or would have no obligation at such time to issue such Letter of Credit in
its revised form (as extended) under the terms hereof (by reason of the provisions of Section 2.10
or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or
before the day that is five Business Days before the Non-Extension Notice Date (1) from the
Administrative Agent that the Required Lenders have elected not to permit such extension or (2)
from the Administrative Agent, any Lender or the Borrower that one or more of the applicable
conditions specified in Section 4.3 is not then satisfied, and in each such case directing the L/C
Issuer not to permit such extension.

(c) Two Business Days after the LC Conditions for a Letter of Credit have been met as
described in Section 2.11 (or if LC Issuer otherwise desires to issue such Letter of Credit
earlier), LC Issuer will issue such Letter of Credit at LC Issuer’s office in Denver, Colorado.
If any provisions of any LC Application conflict with any provisions of this Agreement, the
provisions of this Agreement shall govern and control. Borrower shall promptly examine a copy of
each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any
claim of noncompliance with Borrower’s instructions or other irregularity, Borrower will
immediately notify LC Issuer.

Section 2.12. Reimbursement and Participations.

(a) Reimbursement by Borrower. Each Matured LC Obligation shall constitute a loan by
LC Issuer to Borrower. Borrower promises to pay to LC Issuer, or to LC Issuer’s order, on demand,
the full amount of each Matured LC Obligation, together with interest thereon (i) at the rate
applicable to Base Rate Loans to and including the first Business Day after such demand is made by
LC Issuer and (ii) at the Default Rate applicable to Base Rate Loans on each day thereafter. The
obligation of Borrower to reimburse LC Issuer for each Matured LC Obligation shall be absolute,
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement (including any LC Application) under all circumstances, including the following: (i) any
lack of validity or enforceability of such Letter of Credit or any other agreement or instrument
relating thereto; (ii) the existence of any claim, counterclaim, set-off, defense or other right
that Borrower may have at any time against any beneficiary or any transferee of such Letter of
Credit (or any Person for whom any such beneficiary or any such transferee may be acting), LC
Issuer or any other Person, whether in connection with this Agreement, the transactions
contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto,
or any unrelated transaction; (iii) any draft, demand, certificate or other document presented
under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any
respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay
in the transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit; (iv) any payment by LC Issuer under such Letter of Credit against presentation
of a draft or certificate that does not strictly comply with the terms of such Letter of Credit;
or (v) any other circumstance or happening whatsoever, whether or not similar to any of the
foregoing. Without limiting the generality of the foregoing, it is expressly agreed that the
absolute and unconditional nature of Borrower’s obligations under this section to reimburse LC
Issuer for each drawing under a Letter of Credit will not be excused by the gross negligence or
willful misconduct of LC Issuer. However, the foregoing shall not be construed to excuse LC
Issuer from liability to Borrower to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by Borrower to the extent permitted by
applicable Law) suffered by Borrower that are caused by LC Issuer’s gross negligence or willful
misconduct in determining whether drafts and other documents presented under a Letter of Credit
comply with the terms thereof.

(b) Letter of Credit Advances. If the beneficiary of any Letter of Credit makes a
draft or other demand for payment thereunder then Borrower may, during the interval between the
making thereof and the honoring thereof by LC Issuer, request Lenders to make Loans to Borrower in
the amount of such draft or demand, which Loans shall be made concurrently with LC Issuer’s
payment of such draft or demand and shall be immediately used by LC Issuer to repay the amount of
the resulting Matured LC Obligation. Such a request by Borrower shall be made in compliance with
all of the provisions hereof, provided that for the purposes of the first sentence of Section
2.1(a), the amount of such Loans shall be considered, but the amount of the Matured LC Obligation
to be concurrently paid by such Loans shall not be considered.

(c) Participation by Lenders. LC Issuer irrevocably agrees to grant and hereby
grants to each Lender, and — to induce LC Issuer to issue Letters of Credit hereunder — each
Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from LC Issuer,
on the terms and conditions hereinafter stated and for such Lender’s own account and risk, an
undivided interest equal to such Lender’s Percentage Share of LC Issuer’s obligations and rights
under each Letter of Credit issued hereunder and the amount of each Matured LC Obligation paid by
LC Issuer thereunder. Each Lender unconditionally and irrevocably agrees with LC Issuer that, if
a Matured LC Obligation is paid under any Letter of Credit for which LC Issuer is not reimbursed
in full by Borrower in accordance with the terms of this Agreement and the related LC Application
(including any reimbursement by means of concurrent Loans or by the application of LC Collateral),
such Lender shall (in all circumstances and without set-off or counterclaim) pay to LC Issuer on
demand, in immediately available funds at LC Issuer’s address for notices hereunder, such Lender’s
Percentage Share of such Matured LC Obligation (or any portion thereof which has not been
reimbursed by Borrower). Each Lender’s obligation to pay LC Issuer pursuant to the terms of this
subsection is irrevocable and unconditional. If any amount required to be paid by any Lender to
LC Issuer pursuant to this subsection is paid by such Lender to LC Issuer within three Business
Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to
recover from such Lender, on demand, interest thereon calculated from such due date at the Federal
Funds Rate. If any amount required to be paid by any Lender to LC Issuer pursuant to this
subsection is not paid by such Lender to LC Issuer within three Business Days after the date such
payment is due, LC Issuer shall in addition to such amount be entitled to recover from such
Lender, on demand, interest thereon calculated from such due date at the Default Rate applicable
to Base Rate Loans.

(d) Distributions to Participants. Whenever LC Issuer has in accordance with this
section received from any Lender payment of such Lender’s Percentage Share of any Matured LC
Obligation, if LC Issuer thereafter receives any payment of such Matured LC Obligation or any
payment of interest thereon (whether directly from Borrower or by application of LC Collateral or
otherwise, and excluding only interest for any period prior to LC Issuer’s demand that such Lender
make such payment of its Percentage Share), LC Issuer will distribute to such Lender its
Percentage Share of the amounts so received by LC Issuer; provided, however, that if any such
payment received by LC Issuer must thereafter be returned by LC Issuer, such Lender shall return
to LC Issuer the portion thereof which LC Issuer has previously distributed to it.

(e) Calculations. A written advice setting forth in reasonable detail the amounts
owing under this section, submitted by LC Issuer to Borrower or any Lender from time to time,
shall be conclusive, absent manifest error, as to the amounts thereof.

Section 2.13. Letter of Credit Fees. In consideration of LC Issuer’s issuance of any
Letter of Credit, Borrower agrees to pay (a) to Administrative Agent, for the account of all
Lenders in accordance with their respective Percentage Shares, a letter of credit fee in an amount
equal to the Eurodollar Margin then in effect times the face amount of such Letter of Credit, and
(b) to such LC Issuer for its own account, a letter of credit issuance fee in an amount equal to
one-eighth percent (.125%) per annum times the face amount of such Letter of Credit (but in no
event less than $500 per annum). In addition, Borrower will pay to LC Issuer the LC Issuer’s
customary fees for issuance, amendment and drawing of each Letter of Credit.

Section 2.14. LC Collateral.

(a) LC Obligations in Excess of Borrowing Base. If, after the making of all
mandatory prepayments required under Section 2.7, the outstanding LC Obligations will exceed the
Borrowing Base, then in addition to prepayment of the entire principal balance of the Loans
required under Section 2.7 Borrower will immediately pay to LC Issuer an amount equal to such
excess. LC Issuer will hold such amount as security for the remaining LC Obligations (all such
amounts held as security for LC Obligations being herein collectively called “LC
Collateral”) and the other Obligations, and such collateral may be applied from time to time
to any Matured LC Obligations or other Obligations which are due and payable. Neither this
subsection nor the following subsection shall, however, limit or impair any rights which LC Issuer
may have under any other document or agreement relating to any Letter of Credit, LC Collateral or
LC Obligation, including any LC Application, or any rights which any Lender Party may have to
otherwise apply any payments by Borrower and any LC Collateral under Section 3.1.

(b) Acceleration of LC Obligations. If the Obligations or any part thereof become
immediately due and payable pursuant to Section 8.1 then, unless Required Lenders otherwise
specifically elect to the contrary (which election may thereafter be retracted by Required Lenders
at any time), all LC Obligations shall become immediately due and payable without regard to
whether or not actual drawings or payments on the Letters of Credit have occurred, and Borrower
shall be obligated to pay to LC Issuer immediately an amount equal to the aggregate LC Obligations
which are then outstanding, which amount shall be held by LC Issuer as LC Collateral securing the
remaining LC Obligations and the other Obligations, and such LC Collateral may be applied from
time to time to any Matured LC Obligations or any other Obligations which are due and payable.

(c) Investment of LC Collateral. Pending application thereof, all LC Collateral
shall be invested by LC Issuer in such Investments described in clause (d) of the definition of
Cash Equivalents) as LC Issuer may choose in its sole discretion. All interest on (and other
proceeds of) such Cash Equivalents (other than Investments) shall be reinvested or applied to
Matured LC Obligations or other Obligations which are due and payable. When all Obligations have
been satisfied in full, including all LC Obligations, all Letters of Credit have expired or been
terminated, and all of Borrower’s reimbursement obligations in connection therewith have been
satisfied in full, LC Issuer shall release any remaining LC Collateral. Borrower hereby assigns
and grants to LC Issuer a continuing security interest in all LC Collateral paid by it to LC
Issuer, all Investments purchased with such LC Collateral, and all proceeds thereof to secure its
Matured LC Obligations and its Obligations under this Agreement, each Note, and the other Loan
Documents, and Borrower agrees that such LC Collateral, Investments and proceeds shall be subject
to all of the terms and conditions of the Security Documents. Borrower further agrees that LC
Issuer shall have all of the rights and remedies of a secured party under the Uniform Commercial
Code as adopted in the State of Colorado with respect to such security interest and that an Event
of Default under this Agreement shall constitute a default for purposes of such security interest.

(d) Payment of LC Collateral. When Borrower is required to provide LC Collateral for
any reason and fails to do so on the day when required, LC Issuer or Administrative Agent may
without prior notice to Borrower or any other Restricted Person provide such LC Collateral
(whether by application of proceeds of other Collateral, by transfers from other accounts
maintained with LC Issuer, or otherwise) using any available funds of Borrower or any other Person
also liable to make such payments, and LC Issuer or Administrative Agent will give notice thereof
to Borrower or such other Person, as the case may be, promptly after such application or transfer;
provided, however, the failure to give such notice shall not affect the validity of such
application or transfer. Any such amounts which are required to be provided as LC Collateral and
which are not provided on the date required shall, for purposes of each Security Document, be
considered past due Obligations owing hereunder, and LC Issuer is hereby authorized to exercise
its respective rights under each Security Document to obtain such amounts.

(e) If any Lender is an Impacted Lender, Borrower may from time to time provide cash
collateral to LC Issuer, in an amount equal to the Percentage Shares of all Impacted Lenders’ in
the LC Obligations (the “Impacted Lenders’ Percentage”), to secure the obligations of such
Impacted Lenders under Section 2.12 of this Agreement. Such cash collateral shall be used to
reimburse the Impacted Lenders’ Percentage of drawings under Letters of Credit and other
obligations owing by Impacted Lenders to LC Issuer.

Section 2.15. Obligations of Lenders Several. The obligations of the Lenders hereunder to
make Loans, to fund participations in Letters of Credit and to make payments pursuant to Section
2.2 are several and not joint. The failure of any Lender to make any Loan; to fund any such
participation or to make any payment under Section 10.4(c) on any date required hereunder shall not
relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall
be responsible for the failure of any other Lender to so make its Committed Loan, to purchase its
participation or to make its payment under Section 10.4(c).

ARTICLE III — Payments to Lenders

Section 3.1. General Procedures. Borrower will make each payment which it owes under the
Loan Documents to Administrative Agent for the account of the Lender Party to whom such payment is
owed, in lawful money of the United States of America, without set-off, deduction or counterclaim,
and in immediately available funds. Each such payment must be received by Administrative Agent not
later than 11:00 a.m., Denver, Colorado time, on the date such payment becomes due and payable.
Any payment received by Administrative Agent after such time will be deemed to have been made on
the next following Business Day. Should any such payment become due and payable on a day other
than a Business Day, the maturity of such payment shall be extended to the next succeeding Business
Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be
payable thereon for the period of such extension as provided in the Loan Document under which such
payment is due. Each payment under a Loan Document shall be due and payable at the place set forth
for Administrative Agent on the Lenders Schedule. When Administrative Agent collects or receives
money on account of the Obligations, Administrative Agent shall distribute all money so collected
or received, and each Lender Party shall apply all such money so distributed, as follows (except as
otherwise provided in Section 8.3):

(a) first, for the payment of all Obligations which are then due (and if such money is
insufficient to pay all such Obligations, first to any reimbursements due to Administrative Agent
under Section 6.9 or 10.4 and then to the partial payment of all other Obligations then due in
proportion to the amounts thereof, or as Lender Parties shall otherwise agree);

(b) then for the prepayment of principal of the Loans, together with accrued and unpaid
interest on the principal so prepaid; and

(c) last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first to any interest
then due and payable, then to principal then due and payable, and last to any prepayment of
principal and interest in compliance with Sections 2.6 and 2.7. All distributions of amounts
described in any of subsections (b), (c) or (d) above shall be made by Administrative Agent pro
rata to each Lender Party then owed Obligations described in such subsection in proportion to all
amounts owed to all Lender Parties which are described in such subsection; provided that if any
Lender then owes payments to LC Issuer for the purchase of a participation under Section 2.13(c) or
to Administrative Agent under Section 10.4(c), any amounts otherwise distributable under this
section to such Lender shall be deemed to belong to LC Issuer, or Administrative Agent,
respectively, to the extent of such unpaid payments, and Administrative Agent shall apply such
amounts to make such unpaid payments rather than distribute such amounts to such Lender.

Section 3.2. Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, any Lender (except any Reserve Requirement
reflected in the Adjusted Eurodollar Rate) or LC Issuer;

(ii) subject any Lender or LC Issuer to any tax of any kind whatsoever with respect to
this Agreement, any Letter of Credit, any participation in a Letter of Credit or any
Eurodollar Loan made by it, or change the basis of taxation of payments to Lender or LC
Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section
3.5 and the imposition of, or any change in the rate of, any Excluded Tax payable by such
Lender or LC Issuer); or

(iii) impose on any Lender or LC Issuer or the London interbank market any other
condition, cost or expense affecting this Agreement or Eurodollar Loans made by Lender or
any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan), or to
increase the cost to such Lender or LC Issuer of participating in, issuing or maintaining any
Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of
Credit), or to reduce the amount of any sum received or receivable by such Lender or LC Issuer
hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or
LC Issuer, Borrower will pay to such Lender or LC Issuer, as the case may be, such additional
amount or amounts as will compensate such Lender or LC Issuer, as the case may be, for such
additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or LC Issuer determines that any Change in
Law affecting such Lender or LC Issuer or any lending office of such Lender or such Lender’s or LC
Issuer’s holding company, if any, regarding capital requirements has or would have the effect of
reducing the rate of return on such Lender’s or LC Issuer’s capital or on the capital of such
Lender’s or LC Issuer’s holding company, if any, as a consequence of this Agreement, the
Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by,
such Lender, or the Letters of Credit issued by LC Issuer, to a level below that which such Lender
or LC Issuer or such Lender’s or LC Issuer’s holding company could have achieved but for such
Change in Law (taking into consideration such Lender’s or LC Issuer’s policies and the policies of
such Lender’s or LC Issuer’s holding company with respect to capital adequacy), then from time to
time the Borrower will pay to such Lender or LC Issuer, as the case may be, such additional amount
or amounts as will compensate such Lender or LC Issuer or such Lender’s or LC Issuer’s holding
company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender or LC Issuer setting
forth the amount or amounts necessary to compensate such Lender or LC Issuer or its holding
company, as the case may be, as specified in subsections (a) or (b) of this Section and delivered
to Borrower shall be conclusive absent manifest error. Borrower shall pay such Lender or LC
Issuer, as the case may be, the amount shown as due on any such certificate within ten (10) days
after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or LC Issuer to
demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or LC
Issuer’s right to demand such compensation, provided that Borrower shall not be required to
compensate a Lender or LC Issuer pursuant to this Section for any increased costs incurred or
reductions suffered more than nine months prior to the date that such Lender or LC Issuer, as the
case may be, notifies Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Lender’s or LC Issuer’s intention to claim compensation therefor (except
that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then
the nine-month period referred to above shall be extended to include the period of retroactive
effect thereof).

Section 3.3. Illegality. If any Change in Law after the date hereof shall make it unlawful
for any Lender Party to fund or maintain Eurodollar Loans, then, upon notice by such Lender Party
to Borrower and Administrative Agent, (a) Borrower’s right to elect Eurodollar Loans from such
Lender Party shall be suspended to the extent and for the duration of such illegality, (b) all
Eurodollar Loans of such Lender Party which are then the subject of any Borrowing Notice and which
cannot be lawfully funded shall be funded as Base Rate Loans of such Lender Party, and (c) all
Eurodollar Loans of such Lender Party shall be converted automatically to Base Rate Loans on the
respective last days of the then current Interest Periods with respect to such Loans or within such
earlier period as required by Law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of the then current Interest Period with respect thereto, Borrower shall
pay to such Lender Party such amounts, if any, as may be required pursuant to Section 3.4.

Section 3.4. Funding Losses. In addition to its other obligations hereunder, Borrower will
indemnify each Lender Party against, and reimburse each Lender Party on demand for, any loss or
expense incurred or sustained by such Lender Party (including any loss or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by a Lender Party to
fund or maintain Eurodollar Loans), as a result of (a) any payment or prepayment (whether
authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a day
other than the day on which the applicable Interest Period ends, (b) any payment or prepayment,
whether required hereunder or otherwise, of a Loan made after the delivery, but before the
effective date, of a Continuation/Conversion Notice requesting the continuation of outstanding
Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans, if such
payment or prepayment prevents such Continuation/ Conversion Notice from becoming fully effective,
(c) the failure of any Loan to be made or of any Continuation/Conversion Notice requesting the
continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans
to, Eurodollar Loans to become effective due to any condition precedent not being satisfied or due
to any other action or inaction of any Restricted Person, (d) any Conversion (whether authorized or
required hereunder or otherwise) of all or any portion of any Eurodollar Loan into a Base Rate Loan
or into a different Eurodollar Loan on a day other than the day on which the applicable Interest
Period ends, or (e) any assignment of a Eurodollar Loan on a day other than the last day of the
Interest Period therefor as a result of a request by Borrower pursuant to Section 3.7(b). Such
indemnification shall be on an after-tax basis.

Section 3.5. Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of Borrower hereunder or under any other Loan Document shall be made free and clear of and without
reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if
Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any Other
Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional sums payable under
this Section) Administrative Agent, Lender or LC Issuer, as the case may be, receives an amount
equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make
such deductions and (iii) Borrower shall timely pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. Without limiting the provisions of
paragraph (a) above, Borrower shall timely pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law.

(c) Indemnification by the Borrower. Borrower shall indemnify the Administrative
Agent, each Lender and LC Issuer, within 10 days after demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted
on or attributable to amounts payable under this Section) paid by Administrative Agent, such
Lender or LC Issuer, as the case may be, and any penalties, interest and reasonable expenses
arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes
were correctly or legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to Borrower by a Lender or LC
Issuer (with a copy to Administrative Agent), or by Administrative Agent on its own behalf or on
behalf of a Lender or LC Issuer, shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by Borrower to a Governmental Authority, Borrower shall deliver to
Administrative Agent the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of the return reporting such payment or other evidence
of such payment reasonably satisfactory to Administrative Agent.

(e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which Borrower is resident for
tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments
hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to
Administrative Agent), at the time or times prescribed by applicable law or reasonably requested
by Borrower or Administrative Agent, such properly completed and executed documentation prescribed
by applicable law as will permit such payments to be made without withholding or at a reduced rate
of withholding. In addition, any Lender, if requested by Borrower or Administrative Agent, shall
deliver such other documentation prescribed by applicable law or reasonably requested by Borrower
or Administrative Agent as will enable Borrower or Administrative Agent to determine whether or
not such Lender is subject to backup withholding or information reporting requirements.

Without limiting the generality of the foregoing, in the event that Borrower is resident for
tax purposes in the United States of America, any Foreign Lender shall deliver to Borrower and
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior
to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to
time thereafter upon the request of Borrower or Administrative Agent, but only if such Foreign
Lender is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility
for benefits of an income tax treaty to which the United States of America is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that
such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the
Code, (B) a “10 percent shareholder” of Borrower within the meaning of section 881(c)(3)(B)
of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of
the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

(iv) any other form prescribed by applicable law as a basis for claiming exemption from
or a reduction in United States Federal withholding tax duly completed together with such
supplementary documentation as may be prescribed by applicable law to permit the Borrower to
determine the withholding or deduction required to be made.

(f) Treatment of Certain Refunds. If Administrative Agent, a Lender or LC Issuer
determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as
to which it has been indemnified by Borrower or with respect to which Borrower has paid additional
amounts pursuant to this Section, it shall pay to Borrower an amount equal to such refund (but
only to the extent of indemnity payments made, or additional amounts paid, by Borrower under this
Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of Administrative Agent, such Lender or LC Issuer, as the case may be, and
without interest (other than any interest paid by the relevant Governmental Authority with respect
to such refund), provided that Borrower, upon the request of Administrative Agent, such
Lender or LC Issuer, agrees to repay the amount paid over to Borrower (plus any penalties,
interest or other charges imposed by the relevant Governmental Authority) to Administrative Agent,
such Lender or LC Issuer in the event Administrative Agent, such Lender or LC Issuer is required
to repay such refund to such Governmental Authority. This subsection shall not be construed to
require Administrative Agent, any Lender or LC Issuer to make available its tax returns (or any
other information relating to its taxes that it deems confidential) to Borrower or any other
Person.

	 	 	 
	Section 3.6.Reserved.

	 

	Section 3.7.

	 	Mitigation Obligations; Replacement of Lenders.
	
 
	 	 

(a) Designation of a Different Lending Office. If any Lender requests compensation
under Section 3.2, or requires Borrower to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 3.5, then such Lender
shall use reasonable efforts to designate a different lending office for funding or booking its
Loans hereunder or to assign its rights and obligations hereunder to another of its offices,
branches or affiliates, if, in the judgment of such Lender, such designation or assignment
(i) would eliminate or reduce amounts payable pursuant to Section 3.2 or 3.5, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would
not otherwise be disadvantageous to such Lender. Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender is an Impacted Lender, or if any Lender
requests compensation under Section 3.2, or if Borrower is required to pay any additional amount
to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.5,
then Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance
with and subject to the restrictions contained in, and consents required by, Section 10.5), all of
its interests, rights and obligations under this Agreement and the related Loan Documents to an
assignee that shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment), provided that:

(i) Borrower shall have paid to Administrative Agent the assignment fee specified in
Section 10.5;

(ii) such Lender shall have received payment of an amount equal to the outstanding
principal of its Loans and participations in Matured LC Obligations, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan
Documents (including any amounts under Section 3.4) from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or Borrower (in the case of all other
amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under
Section 3.2 or payments required to be made pursuant to Section 3.5, such assignment will
result in a reduction in such compensation or payments thereafter; and

(iv) such assignment does not conflict with applicable law.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a
result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require
such assignment and delegation cease to apply.

Section 3.8. Payments by Borrower; Presumptions by Administrative Agent. Unless
Administrative Agent shall have received notice from Borrower prior to the date on which any
payment is due to Administrative Agent for the account of Lenders or LC Issuer hereunder that
Borrower will not make such payment, Administrative Agent may assume that Borrower has made such
payment on such date in accordance herewith and may, in reliance upon such assumption, distribute
to the Lenders or LC Issuer, as the case may be, the amount due. In such event, if Borrower has
not in fact made such payment, then each of the Lenders or LC Issuer, as the case may be, severally
agrees to repay to Administrative Agent forthwith on demand the amount so distributed to such
Lender or LC Issuer, with interest thereon, for each day from and including the date such amount is
distributed to it to but excluding the date of payment to Administrative Agent, at the greater of
the Federal Funds Rate and a rate determined by Administrative Agent in accordance with banking
industry rules on interbank compensation.

(k) Completion of Proceedings. All partnership, corporate and other proceedings

ARTICLE V — Representations and Warranties

To confirm each Lender’s understanding concerning Restricted Persons and Restricted Persons’
businesses, properties and obligations and to induce Administrative Agent and each Lender to enter
into this Agreement and to extend credit hereunder, Borrower represents and warrants to
Administrative Agent and each Lender that:

Section 5.1. No Default. No Restricted Person is in default in the performance of any of
its covenants and agreements contained in any Loan Document. No event has occurred and is
continuing which constitutes a Default.

Section 5.2. Organization and Good Standing. Each Restricted Person is duly organized,
validly existing and, as applicable, in good standing under the Laws of its jurisdiction of
organization, having all powers required to carry on its business and enter into and carry out the
transactions contemplated hereby. Each Restricted Person is duly qualified, in good standing, and
authorized to do business in all other jurisdictions within the United States wherein Collateral or
a principal office of Borrower is located. Each Restricted Person has taken all actions and
procedures customarily taken in order to enter, for the purpose of conducting business or owning
property, each jurisdiction outside the United States wherein the character of the properties owned
or held by it or the nature of the business transacted by it makes such actions and procedures
desirable.

Section 5.3. Authorization. Each Restricted Person has duly taken all action necessary to
authorize the execution and delivery by it of the Loan Documents to which it is a party and to
authorize the consummation of the transactions contemplated thereby and the performance of its
obligations thereunder. Borrower is duly authorized to borrow funds hereunder.

Section 5.4. No Conflicts or Consents. The execution and delivery by the various
Restricted Persons of the Loan Documents to which each is a party, the performance by each of its
obligations under such Loan Documents, and the consummation of the transactions contemplated by the
various Loan Documents, do not and will not (a) conflict with, violate or result in a breach of any
provision of (i) any Law, (ii) the organizational documents of any Restricted Person, or (iii) any
material agreement, judgment, license, order or permit applicable to or binding upon any Restricted
Person, (b) result in the acceleration of any Indebtedness owed by any Restricted Person, or
(c) result in or require the creation of any Lien upon any assets or properties of any Restricted
Person except as expressly contemplated or permitted in the Loan Documents. Except (i) as
expressly contemplated in the Loan Documents and (ii) such as have been obtained or made and are in
full force and effect, no permit, consent, approval, authorization or order of, and no notice to or
filing with, any Tribunal or third party is required on the part of or in respect of a Restricted
Person in connection with the execution, delivery or performance by any Restricted Person of any
Loan Document or to consummate any transactions contemplated by the Loan Documents.

Section 5.5. Enforceable Obligations. This Agreement is, and the other Loan Documents when
duly executed and delivered will be, legal, valid and binding obligations of each Restricted Person
which is a party hereto or thereto, enforceable against such Restricted Person in accordance with
their terms except as such enforcement may be limited by Debtor Relief Laws.

Section 5.6. Initial Financial Statements. Restricted Persons have heretofore delivered to
each Lender true, correct and complete copies of the Initial Financial Statements. Each of the
Initial Financial Statements fairly present Borrower’s Consolidated financial position at the date
thereof and the Consolidated results of Borrower’s operations and Borrower’s Consolidated cash
flows for the period thereof. Since the date of the annual Initial Financial Statements no
Material Adverse Change has occurred, except as reflected in Section 5.6 of the Disclosure
Schedule. All Initial Financial Statements other than pro forma financial statements were prepared
in accordance with GAAP. All Initial Financial Statements that are pro forma financial statements
were prepared in good faith based upon assumptions specified therein with such pro forma
adjustments as have been accepted by Administrative Agent.

Section 5.7. Other Obligations and Restrictions. No Restricted Person has any outstanding
Indebtedness of any kind (including contingent obligations, tax assessments, and unusual forward or
long-term commitments) which are, in the aggregate, material to Borrower or material with respect
to Borrower’s Consolidated financial condition and not shown in the Initial Financial Statements or
disclosed in Section 5.7 of the Disclosure Schedule or otherwise permitted under Section 7.1.
Except as shown in the Initial Financial Statements or disclosed in Section 5.7 of the Disclosure
Schedule, no Restricted Person is subject to or restricted by any material franchise, contract,
deed, charter restriction, or other instrument or restriction.

Section 5.8. Full Disclosure. No certificate, statement or other information delivered
herewith or heretofore by any Restricted Person to any Lender in connection with the negotiation of
this Agreement or in connection with any transaction contemplated hereby contains any untrue
statement of a material fact or omits to state any material fact known to any Restricted Person
(other than industry-wide risks normally associated with the types of businesses conducted by
Restricted Persons) necessary to make the statements contained herein or therein not misleading as
of the date made or deemed made. There is no material fact known to any Restricted Person (other
than industry-wide risks normally associated with the types of businesses conducted by Restricted
Persons) that has not been disclosed to each Lender in writing. There are no statements or
conclusions in any Engineering Report which are based upon or include misleading information or
fail to take into account material information regarding the matters reported therein, it being
understood that each Engineering Report is necessarily based upon professional opinions, estimates
and projections and that Borrower does not warrant that such opinions, estimates and projections
will ultimately prove to have been accurate. Borrower has heretofore delivered to each Lender true,
correct and complete copies of the Initial Engineering Report.

Section 5.9. Litigation. Except as disclosed in the Initial Financial Statements or in
Section 5.9 of the Disclosure Schedule: (a) there are no actions, suits or legal, equitable,
arbitrative or administrative proceedings pending before any Tribunal, or to the knowledge of any
Restricted Person threatened, against any Restricted Person or affecting any Collateral (including
any which challenge or otherwise pertain to any Restricted Person’s title to any Collateral) before
any Tribunal, and (b) there are no outstanding judgments, injunctions, writs, rulings or orders by
any such Tribunal against any Restricted Person or any Restricted Person’s stockholders, partners,
members, directors or officers or affecting any Collateral or any of its material assets or
property.

of the Disclosure Schedule. Except as disclosed in the Initial Financial Statements or in Section
5.10 of the Disclosure Schedule, no Termination Event has occurred with respect to any ERISA Plan
and all ERISA Affiliates are in compliance with ERISA in all material respects. No ERISA Affiliate
is required to contribute to, or has any other absolute or contingent liability in respect of, any
“multiemployer plan” as defined in Section 4001 of ERISA. Except as set forth in Section 5.10 of
the Disclosure Schedule: (a) no “accumulated funding deficiency” (as defined in Section 412(a) of
the Internal Revenue Code) exists with respect to any ERISA Plan, whether or not waived by the
Secretary of the Treasury or his delegate, and (b) the current value of each ERISA Plan’s benefits
does not exceed the current value of such ERISA Plan’s assets available for the payment of such
benefits by more than the Threshold Amount.

Section 5.11. Environmental and Other Laws. Except as disclosed in Section 5.11 of the
Disclosure Schedule: (a) Restricted Persons are conducting their businesses in material compliance
with all applicable Laws, including Environmental Laws, and have and are in compliance with all
licenses and permits required under any such Laws; (b) none of the operations or properties of any
Restricted Person is the subject of federal, state or local investigation evaluating whether any
material remedial action is needed to respond to a release of any Hazardous Materials into the
environment or to the improper storage or disposal (including storage or disposal at offsite
locations) of any Hazardous Materials; (c) no Restricted Person (and to the best knowledge of
Borrower, no other Person) has filed any notice under any Law indicating that any Restricted Person
is responsible for the improper release into the environment, or the improper storage or disposal,
of any material amount of any Hazardous Materials or that any Hazardous Materials have been
improperly released, or are improperly stored or disposed of, upon any property of any Restricted
Person; (d) no Restricted Person has transported or arranged for the transportation of any
Hazardous Material to any location which is (i) listed on the National Priorities List under the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, listed
for possible inclusion on such National Priorities List by the Environmental Protection Agency in
its Comprehensive Environmental Response, Compensation and Liability Information System List, or
listed on any similar state list or (ii) the subject of federal, state or local enforcement actions
or other investigations which may lead to claims against any Restricted Person for clean-up costs,
remedial work, damages to natural resources or for personal injury claims (whether under
Environmental Laws or otherwise); and (e) no Restricted Person otherwise has any known material
contingent liability under any Environmental Laws or in connection with the release into the
environment, or the storage or disposal, of any Hazardous Materials. Each Restricted Person
undertook, at the time of its acquisition of each of its material properties, all appropriate
inquiry into the previous ownership and uses of the Property and any potential environmental
liabilities associated therewith.

Section 5.12. Names and Places of Business. No Restricted Person has, during the five
years preceding the Closing Date, been known by, or used any other trade or fictitious name, except
as disclosed in Section 5.12 of the Disclosure Schedule or been organized in a jurisdiction other
than its jurisdiction of organization as of the date hereof.

Section 5.13. Subsidiaries. As of the Closing Date, (i) Borrower does not have any
Subsidiary except those listed in Section 5.13 of the Disclosure Schedule or disclosed to
Administrative Agent in writing and (ii) no Restricted Person has any equity investments in any
other Person except those listed in Section 5.13 of the Disclosure Schedule and Permitted
Investments. Borrower owns, directly or indirectly, the equity interests in each of its
Subsidiaries which is indicated in Section 5.13 of the Disclosure Schedule or as disclosed to
Administrative Agent in writing.

Section 5.14. Government Regulation. Neither Borrower nor any other Restricted Person
owing Obligations is (a) an “investment company” or a company “controlled” by an “investment
company” within the meaning of the Investment Company Act of 1940, as amended, or (b) subject to
regulation under the Federal Power Act, as amended, or any other Law which regulates the incurring
by such Person of Indebtedness, including Laws relating to common contract carriers or the sale of
electricity, gas, steam, water or other public utility services.

Section 5.15. Solvency. Upon giving effect to the making of the Loans, the execution and
delivery of the Loan Documents by Borrower and each Guarantor and the consummation of the
transactions contemplated hereby, no Restricted Person will be Insolvent.

Section 5.16. Taxes. Each Restricted Person has filed all United States Federal income tax
returns and all other material tax returns that are required to be filed by it and have paid all
taxes due pursuant to such returns or pursuant to any assessment received by any Restricted Person
and all other penalties or charges. The charges, accruals and revenues on the books of each
Restricted Person in respect of taxes and other governmental charges are, in the opinion of
Borrower, adequate. No Restricted Person has given or been requested to give a waiver of the
statute of limitations relating to the payment of any federal or other taxes.

Section 5.17. Regulation U. None of the Borrower and its Subsidiaries are engaged in the
business of extending credit for the purpose of purchasing or carrying Margin Stock, and no
proceeds of any Loans will be used for a purpose which violates Regulation U.

Section 5.18. Title to Properties. Each Restricted Person has (a) good and defensible
title to, or valid leasehold interests in, all of the Oil and Gas Properties covered by the most
recent Engineering Report and (b) good and valid title to, or valid leasehold interests in,
licenses of, or rights to use, all other Collateral owned or leased by such Restricted Person and
all of its other material properties and assets necessary or used in the ordinary conduct of its
business, in each case free and clear of all Liens, encumbrances, or adverse claims other than
Permitted Liens and of all impediments to the use of such properties and assets in such Restricted
Person’s business, except that no representation or warranty is made with respect to any Oil and
Gas Property to which no Proved Reserves are properly attributed. Other than changes which arise
pursuant to non-consent provisions of operating agreements or other agreements (if any) described
in Exhibit A to any Security Document: (x) each Restricted Person owns the net interests in
production attributable to the wells and units of such Restricted Person evaluated in the most
recent Engineering Report subject to Permitted Liens and (y) the ownership of such properties does
not in the aggregate in any material respect obligate such Restricted Person to bear the costs and
expenses relating to the maintenance, development and operations of such properties in an amount
materially in excess of the working interest of such properties set forth in the most recent
Engineering Reports without a corresponding increase in the net revenue interests for such
properties. Upon delivery of each Engineering Report furnished to the Lenders pursuant to Sections
6.2, the statements made in the preceding sentences of this section and in Sections 5.18 through
5.21 shall be true with respect to such Engineering Report.

Section 5.19. Leases and Contracts; Performance of Obligations. The leases, contracts and
other agreements (in this section called the “Leases and Contracts”) forming a part of the Oil and
Gas Properties of the Restricted Persons covered by the most recent Engineering Report are in full
force and effect. All rents, royalties and other payments due and payable under the Leases and
Contracts or under any Permitted Liens have been properly and timely paid. No Restricted Person is
in default with respect to its obligations (and no Restricted Person is aware of any default by any
third party with respect to such third party’s obligations) under any of the Leases and Contracts
or under any Permitted Liens, where such default could adversely affect the ownership or operation
of such Oil and Gas Properties. No Restricted Person is currently accounting for any royalties, or
overriding royalties or other payments out of production, on a basis (other than delivery in kind)
less favorable to such Restricted Person than proceeds received by such Restricted Person
(calculated at the well) from sale of production, and no Restricted Person has any liability (or
alleged liability) to account for the same on any such less favorable basis.

Section 5.20. Sale of Production.

(a) Sales Contracts. Except as set forth in the Disclosure Schedule, no Oil and Gas
Property covered by the most recent Engineering Report is subject to any contractual or other
arrangement (i) whereby payment for production is or can be deferred for a substantial period
after the month in which such production is delivered (in the case of oil, not in excess of 60
days, and in the case of gas, not in excess of 90 days) or (ii) whereby payments are made to a
Restricted Person other than by checks, drafts, wire transfer advises or other similar writings,
instruments or communications for the immediate payment of money. Except as disclosed in the
Disclosure Schedule: (i) no Oil and Gas Property covered by the most recent Engineering Report is
subject to any contractual or other arrangement for the sale, processing or transportation of
production (or otherwise related to the marketing of production) which cannot be canceled on 120
days’ (or less) notice and (ii) all contractual or other arrangements for the sale, processing or
transportation of production (or otherwise related to the marketing of production) are bona fide
arm’s length transactions made on the best terms available with third parties not affiliated with
Restricted Persons. If such Oil and Gas Property is subject to a production sales contract or
marketing contract, a Restricted Person is receiving a price for delivery of production calculated
in accordance with the terms of such contract. No Restricted Person is having deliveries of
production from such Oil and Gas Property covered by the most recent Engineering Report curtailed
substantially below such property’s delivery capacity.

(b) Take or Pay. Except as set forth in the Disclosure Schedule, no Restricted
Person, nor any Restricted Person’s predecessors in title, has received prepayments (including
payments for gas not taken pursuant to “take or pay” or other similar arrangements) for any oil,
gas or other hydrocarbons produced or to be produced from any Oil and Gas Properties covered by
the most recent Engineering Report after the date hereof. Except as set forth in the Disclosure
Schedule, no Oil and Gas Property covered by the most recent Engineering Report is subject to any
“take or pay” or other similar arrangement (i) which can be satisfied in whole or in part by the
production or transportation of gas from other properties or (ii) as a result of which production
from any Oil and Gas Property covered by the most recent Engineering Report may be required to be
delivered to one or more third parties without payment (or without full payment) therefor as a
result of payments made, or other actions taken, with respect to other properties.

Section 5.21. Operation of Oil and Gas Properties. The Oil and Gas Properties covered by
the most recent Engineering Report (and all properties unitized therewith) are being (and, to the
extent the same could adversely affect the ownership or operation of the Oil and Gas Properties
covered by the most recent Engineering Report after the date hereof, have in the past been)
maintained, operated and developed in a good and workmanlike manner, in accordance with prudent
industry standards and in conformity in all material respects with (a) all applicable Laws, (b) all
oil, gas or other mineral leases and other contracts and agreements forming a part of the Oil and
Gas Property covered by the most recent Engineering Report, and (c) Permitted Liens. There are no
dry holes, or otherwise inactive wells, located on the Oil and Gas Properties covered by the most
recent Engineering Report or on lands pooled or unitized therewith, except for wells that have been
properly plugged and abandoned or which will be properly plugged and abandoned as required by
applicable state regulations. Each Restricted Person has all governmental licenses and permits
necessary or appropriate to own and operate its Oil and Gas Properties covered by the most recent
Engineering Report, and no Restricted Person has received notice of any violations in respect of
any such licenses or permits. The representations and warranties set forth in this Section 5.21
with respect to Oil and Gas Properties for which Borrower is not the operator are made to the best
of Borrower’s knowledge.

Section 5.22. Ad Valorem and Severance Taxes; Litigation. Each Restricted Person has paid
and discharged all ad valorem taxes that are payable and have been assessed against its Oil and Gas
Property or any part thereof and all production, severance and other taxes that are payable and
have been assessed against, or measured by, the production or the value, or proceeds, of the
production therefrom. There are no suits, actions, claims, investigations, inquiries, proceedings
or demands pending (or, to any Restricted Person’s knowledge, threatened) which might affect the
Oil and Gas Property, including any which challenge or otherwise pertain to any Restricted Person’s
title to any Oil and Gas Property or rights to produce and sell oil and gas therefrom.

Section 5.23. Limitation to Proved Reserves. No representation or warranty is made in this
Sections 5.18 through 5.22 with respect to any Oil and Gas Property to which no Proved Reserves are
properly attributed.

ARTICLE VI — Affirmative Covenants of Borrower

To conform with the terms and conditions under which each Lender is willing to have credit
outstanding to Borrower, and to induce each Lender to enter into this Agreement and extend credit
hereunder, Borrower warrants, covenants and agrees that until the full and final payment of the
Obligations and the termination of this Agreement (as determined without regard to unasserted
indemnity claims), unless Required Lenders have previously agreed otherwise:

Section 6.1. Payment and Performance. Each Restricted Person will pay all amounts due
under the Loan Documents, to which it is a party, in accordance with the terms thereof and will
observe, perform and comply with every covenant, term and condition set forth in the Loan Documents
to which it is a party. Borrower will cause each other Restricted Person to observe, perform and
comply with every such term, covenant and condition in any Loan Document.

Section 6.2. Books, Financial Statements and Reports. Each Restricted Person will at all
times maintain full and accurate books of account and records. Borrower will maintain and will
cause its Subsidiaries to maintain a standard system of accounting, will maintain its Fiscal Year,
and will furnish the following statements and reports to each Lender Party at Borrower’s expense:

(a) As soon as available, and in any event within ninety (90) days after the end of each
Fiscal Year, complete Consolidated financial statements of Borrower together with all notes
thereto, prepared in reasonable detail in accordance with GAAP, together with an unqualified
opinion, based on an audit using generally accepted auditing standards, by a “Big Four” public
accounting firm or another independent certified public accounting firm of nationally recognized
standing selected by Borrower and reasonably acceptable to Administrative Agent, stating that such
Consolidated financial statements have been so prepared. These financial statements shall contain
a Consolidated balance sheet as of the end of such Fiscal Year and Consolidated statements of
earnings, of cash flows, and of changes in owners’ equity for such Fiscal Year, each setting forth
in comparative form the corresponding figures for the preceding Fiscal Year.

(b) As soon as available, and in any event within forty-five (45) days after the end of each
Fiscal Quarter, Borrower’s Consolidated balance sheet as of the end of such Fiscal Quarter and
Consolidated statements of Borrower’s earnings and cash flows for such Fiscal Quarter and for the
period beginning on the first day of the then current Fiscal Year to the end of such Fiscal
Quarter, all in reasonable detail and prepared in accordance with GAAP, subject to changes
resulting from normal year-end adjustments and the absence of footnotes. In addition Borrower
will, together with each such set of financial statements and each set of financial statements
furnished under subsection (a) of this section, furnish a certificate in the form of Exhibit D
signed by a Responsible Officer of Borrower stating that such financial statements are accurate
and complete (subject to normal year-end adjustments and the absence of footnotes), stating that
he/she has reviewed the Loan Documents, containing calculations showing compliance (or
non-compliance) at the end of such Fiscal Quarter with the requirements of Sections 7.11 and 7.12
and stating that no Default exists at the end of such Fiscal Quarter or at the time of such
certificate or specifying the nature and period of existence of any such Default.

(c) Within forty-five (45) days after the end of each Fiscal Quarter, Borrower will furnish a
report (in form reasonably satisfactory to Administrative Agent) of all Hedging Contracts of
Borrower and each of its Subsidiaries, setting forth the type, term, effective date, termination
date and notional amounts or volumes and the counterparty to each such agreement.

(d) By March 1 of each year, an Engineering Report prepared by Independent Engineers as of
December 31 of the immediately preceding year concerning all Oil and Gas Properties and interests
owned by any Restricted Person which are located in or offshore of the United States and which
have attributable to them Proved Reserves. This report shall be satisfactory to Administrative
Agent and shall contain information and analysis comparable in scope to that contained in the
Initial Engineering Report. This report shall distinguish (or shall be delivered together with a
certificate from an appropriate officer of Borrower which distinguishes) those properties treated
in the report which are Collateral from those properties treated in the report which are not
Collateral.

(e) By September 1 of each year, and promptly following notice of a Special Determination
under Section 2.9, an Engineering Report prepared as of the preceding July 1 (or the last day of
the preceding calendar month in the case of a Special Determination) by Staff Engineers (or at
Borrower’s option, by the Independent Engineers), together with an accompanying report on property
sales, property purchases and changes in categories, both in the same form and scope as the
reports in (d) above.

(f) As soon as available, and in any event within forty-five (45) days after the end of each
Fiscal Quarter, a report describing by lease or unit the gross volume of production and sales
attributable to production during such quarter from the properties described in the most recent
Engineering Report and describing the related severance taxes, other taxes, and leasehold
operating expenses and capital costs attributable thereto and incurred during such quarter.

(g) With each Engineering Report delivered pursuant to Sections 6.2 (d) and (e), Borrower
shall deliver to Lender a twelve-month projected cash budget for the Restricted Persons in form
acceptable to Administrative Agent.

Section 6.3. Other Information and Inspections. Each Restricted Person will furnish to
each Lender any information which Administrative Agent may from time to time request concerning any
provision of the Loan Documents, any Collateral, or any matter in connection with Restricted
Persons’ businesses, properties, prospects, financial condition and operations. Each Restricted
Person will permit representatives appointed by Administrative Agent (including independent
accountants, auditors, agents, attorneys, appraisers and any other Persons) to visit and inspect
during normal business hours any of such Restricted Person’s property, including its books of
account, other books and records, and any facilities or other business assets, and to make extra
copies therefrom and photocopies and photographs thereof, and to write down and record any
information such representatives obtain.

Section 6.4. Notice of Material Events and Change of Address. Borrower will promptly,
after becoming aware thereof, notify each Lender Party in writing, stating that such notice is
being given pursuant to this Agreement, of:

(a) The occurrence of any Material Adverse Change;

(b) the occurrence of any Default;

(c) the acceleration of the maturity of any Indebtedness owed by any Restricted Person or of
any default by any Restricted Person under any indenture, mortgage, agreement, contract or other
instrument to which any of them is a party or by which any of them or any of their properties is
bound, if such acceleration or default could cause a Material Adverse Change;

(d) the occurrence of any Termination Event;

(e) any claim of $500,000 or more, any notice of potential liability of any Restricted Person
under any Environmental Laws which might exceed such amount, or any other material adverse claim
asserted against any Restricted Person or with respect to any Restricted Person’s properties; and

(f) the filing of any suit or proceeding against any Restricted Person in which an adverse
decision could cause a liability to such Restricted Person in excess of the $1,000,000.

Upon the occurrence of any of the foregoing Restricted Persons will take all necessary or
appropriate steps to remedy promptly any such Material Adverse Change, Default, acceleration,
default, or Termination Event, to protect against any such adverse claim, to defend any such suit
or proceeding, and to resolve all controversies on account of any of the foregoing. Borrower will
also notify Administrative Agent and Administrative Agent’s counsel in writing at least twenty
Business Days prior to the date that any Restricted Person changes its name or the location of its
chief executive office or its location under the Uniform Commercial Code.

Section 6.5. Maintenance of Properties. Each Restricted Person will maintain, preserve,
protect, and keep all Collateral and all other property used or useful in the conduct of its
business in good condition (ordinary wear and tear excepted) in accordance with prudent industry
standards, and in material compliance with all applicable Laws, in conformity with all applicable
contracts, servitudes, leases and agreements, and will from time to time make all repairs, renewals
and replacements needed to enable the business and operations carried on in connection therewith to
be promptly and advantageously conducted at all times. The foregoing shall not prohibit a
Restricted Person from surrendering or releasing any oil and gas lease if the Restricted Person
reasonably determines that the prospective production of oil and gas from such lease will not be
economical.

Section 6.6. Maintenance of Existence and Qualifications. Each Restricted Person will
maintain and preserve its existence and its rights and franchises in full force and effect and will
qualify to do business in all states or jurisdictions where required by applicable Law, except
where the failure so to qualify could cause a Material Adverse Change.

Section 6.7. Payment of Trade Indebtedness, Taxes, etc. Each Restricted Person will (a)
timely file all required tax returns including any extensions; (b) timely pay all taxes,
assessments, and other governmental charges or levies imposed upon it or upon its income, profits

and discharge all obligations owed by it on ordinary trade terms to vendors, suppliers and other
Persons providing goods and services used by it in the ordinary course of its business; (d) pay and
discharge before the same becomes delinquent all other obligations now or hereafter owed by it,
other than royalty payments suspended in the ordinary course of business; and (e) maintain
appropriate accruals and reserves for all of the foregoing in accordance with GAAP. Each
Restricted Person may, however, delay paying or discharging any of the foregoing so long as it is
in good faith contesting the validity thereof by appropriate proceedings, if necessary, and has set
aside on its books adequate reserves therefore which are required by GAAP.

Section 6.8. Insurance.

(a) Each Restricted Person shall at all times maintain (at its own expense) insurance for its
property in accordance with the Insurance Schedule in at least such amounts, with at least such
limitations on deductibles, and against such risks, in such form and with such financially sound
and reputable insurers as shall be satisfactory to Administrative Agent from time to time. Each
Restricted Person shall at all times maintain insurance against its liability for injury to
persons or property in accordance with the Insurance Schedule, which insurance shall be by
financially sound and reputable insurers.

(b) All insurance policies covering Collateral shall be modified or endorsed as necessary to
(A) name Administrative Agent as “loss payee” or “additional insured” as applicable, (B) prevent
any expiration or cancellation of the coverage provided by such policies without at least thirty
(30) days prior written notice to Administrative Agent by the insurer.

(c) Upon the occurrence and during the continuance of an Event of Default, all insurance
payments in respect of such Collateral in excess of $1,000,000 shall be paid to Administrative
Agent and shall be applied to the prepayment of the Obligations unless otherwise agreed to by
Administrative Agent and Borrower.

Section 6.9. Performance on Borrower’s Behalf. If any Restricted Person fails to pay any
taxes, insurance premiums, expenses, attorneys’ fees or other amounts it is required to pay under
any Loan Document, Administrative Agent may pay the same. Borrower shall immediately reimburse
Administrative Agent for any such payments and each amount paid by Administrative Agent shall
constitute an Obligation owed hereunder which is due and payable on the date such amount is paid by
Administrative Agent.

Section 6.10. Interest. Borrower hereby promises to Administrative Agent and each Lender
Party to pay interest at the Default Rate applicable to Base Rate Loans on all Obligations
(including Obligations to pay fees or to reimburse or indemnify Administrative Agent or any Lender

which is covered by Section 2.5 and 2.12(a)) which Borrower has in this Agreement promised to pay
to Administrative Agent or such Lender Party and which are not paid when due. Such interest shall
accrue from the date such Obligations become due until they are paid.

Section 6.11. Compliance with Agreements and Law. Each Restricted Person will perform all
material obligations it is required to perform under the terms of each indenture, mortgage, deed of
trust, security agreement, lease, franchise, agreement, contract or other instrument or obligation
to which it is a party or by which it or any of its properties is bound. Each Restricted Person
will conduct its business and affairs in compliance with all Laws applicable thereto. Each
Restricted Person will cause all licenses and permits necessary or appropriate for the conduct of
its business and the ownership and operation of its property used and useful in the conduct of its
business to be at all times maintained in good standing and in full force and effect.

Section 6.12. Environmental Matters; Environmental Reviews.

(a) Each Restricted Person will comply in all material respects with all Environmental Laws
now or hereafter applicable to such Restricted Person, as well as all contractual obligations and
agreements with respect to environmental remediation or other environmental matters, and shall
obtain, at or prior to the time required by applicable Environmental Laws, all environmental,
health and safety permits, licenses and other authorizations necessary for its operations and will
maintain such authorizations in full force and effect. No Restricted Person will do anything or
permit anything to be done which will subject any of its properties to any remedial obligations
under, or result in noncompliance with applicable permits and licenses issued under, any
applicable Environmental Laws, assuming disclosure to the applicable governmental authorities of
all relevant facts, conditions and circumstances. Upon Administrative Agent’s reasonable request,
at any time and from time to time, Borrower will provide at its own expense an environmental
inspection of any of the Restricted Persons’ material real properties and audit of their
environmental compliance procedures and practices, in each case from an engineering or consulting
firm approved by Administrative Agent.

(b) Borrower will promptly furnish to Administrative Agent copies of all written notices of
violation, orders, claims, citations, complaints, penalty assessments, suits or other proceedings
received by any Restricted Person, or of which Borrower otherwise has notice, pending or
threatened against any Restricted Person by any Governmental Authority with respect to any alleged
violation of or non-compliance with any Environmental Laws or any permits, licenses or
authorizations in connection with any Restricted Person’s ownership or use of its properties or
the operation of its business which could reasonably be expected to result in liability of a
Restricted Person in excess of $1,000,000.

(c) Borrower will promptly furnish to Administrative Agent all requests for information,
notices of claim, demand letters, and other notifications, received by Borrower in connection with
any Restricted Person’s ownership or use of its properties or the conduct of its business,
relating to potential responsibility with respect to any investigation or clean-up of Hazardous
Material at any location.

Section 6.13. Evidence of Compliance. Each Restricted Person will furnish to each Lender
at such Restricted Person’s or Borrower’s expense all evidence which Administrative Agent from time
to time reasonably requests in writing as to the accuracy and validity of or compliance with all
representations, warranties and covenants made by any Restricted Person in the Loan Documents, the
satisfaction of all conditions contained therein, and all other matters pertaining thereto.

Section 6.14. Bank Accounts; Offset. To secure the repayment of the Obligations Borrower
hereby grants to each Lender and LC Issuer a security interest, a lien, and a right of offset, each
of which shall be in addition to all other interests, liens, and rights of any Lender and LC Issuer
at common Law, under the Loan Documents, or otherwise, and each of which shall be upon and against
(a) any and all moneys, securities or other property (and the proceeds therefrom) of Borrower now
or hereafter held or received by or in transit to any Lender or LC Issuer from or for the account
of Borrower, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b)
any and all deposits (general or special, time or demand, provisional or final) of Borrower with
any Lender or LC Issuer and (c) any other credits and claims of Borrower at any time existing
against any Lender or LC Issuer, including claims under certificates of deposit. At any time and
from time to time after the occurrence and during the continuance of any Default, each Lender and
LC Issuer is hereby authorized to foreclose upon, or to offset against the Obligations then due and
payable (in either case without notice to Borrower), any and all items hereinabove referred to.
The remedies of foreclosure and offset are separate and cumulative, and either may be exercised
independently of the other without regard to procedures or restrictions applicable to the other.

Section 6.15. Guaranties of Borrower’s Subsidiaries. Each Subsidiary of Borrower now
existing or created, acquired or coming into existence after the date hereof shall, promptly upon
request by Administrative Agent, execute and deliver to Administrative Agent an absolute and
unconditional guaranty of the timely repayment of the Obligations and the due and punctual
performance of the obligations of Borrower hereunder, which guaranty shall be satisfactory to
Administrative Agent in form and substance. Each Subsidiary of Borrower existing on the date
hereof shall duly execute and deliver such a guaranty prior to the making of any Loan hereunder.
Borrower will cause each of its Subsidiaries to deliver to Administrative Agent, simultaneously
with its delivery of such a guaranty, written evidence satisfactory to Administrative Agent and its
counsel that such Subsidiary has taken all company action necessary to duly approve and authorize
its execution, delivery and performance of such guaranty and any other documents which it is
required to execute.

Section 6.16. Agreement to Deliver Security Documents. Borrower agrees to deliver and to
cause each other Restricted Person to deliver, to further secure the Obligations whenever requested
by Administrative Agent in its sole and absolute discretion, deeds of trust, mortgages, chattel
mortgages, security agreements, financing statements and other Security Documents in form and
substance satisfactory to Administrative Agent for the purpose of granting, confirming, and
perfecting first and prior liens or security interests in any real or personal property which is at
such time Collateral or which was intended to be Collateral pursuant to any Security Document
previously executed and not then released by Administrative Agent.

Section 6.17. Collateral.

(a) At all times the Secured Obligations shall be secured by first and prior Liens (subject
only to Permitted Liens) covering and encumbering (i) at least eighty percent (80%) of the
Restricted Person’s Proved Reserves, and (ii) one hundred percent (100%) of the issued and
outstanding Equity Interest of each Subsidiary of Borrower, and (iii) all other personal property
of the Restricted Persons. On the Closing Date, Borrower and its Subsidiaries shall deliver to
Administrative Agent for the ratable benefit of each Lender, Security Documents covering the
foregoing, each in form and substance acceptable to Administrative Agent.

(b) To the extent necessary to comply with the first sentence of Section 6.17(a), (i) within
30 days after each Determination Date and after any material acquisition, Borrower and its
Subsidiaries shall execute and deliver to Administrative Agent, for the ratable benefit of each
Lender, any new deeds of trust, mortgages, chattel mortgages, security agreements and financing
statements in form and substance acceptable to Administrative Agent and duly executed by Borrower
and any such Subsidiary (as applicable) together with such other assignments, conveyances,
amendments, agreements and other writings (each duly authorized and executed) as Administrative
Agent shall deem necessary or appropriate to grant, evidence and perfect the Liens required by
this Section 6.17.

(c) Borrower also agrees to make available for review favorable title opinions, updates of
title opinions or landman reports acceptable to Administrative Agent with respect to Oil and Gas
Properties described in subsection (b) immediately above confirming that such Restricted Person
has good and defensible title to such properties and interests, free and clear of all Liens other
than Permitted Liens.

Section 6.18. Production Proceeds. Notwithstanding that, by the terms of the various
Security Documents, Restricted Persons are and will be assigning to Administrative Agent and
Lenders all of the “Production Proceeds” (as defined therein) accruing to the property covered
thereby, so long as no Default has occurred Restricted Persons may continue to receive from the
purchasers of production all such Production Proceeds, subject, however, to the Liens created under
the Security Documents, which Liens are hereby affirmed and ratified. Upon the occurrence of a
Default, Administrative Agent and Lenders may exercise all rights and remedies granted under the
Security Documents subject to the terms thereof, including the right to obtain possession of all
Production Proceeds then held by Restricted Persons or to receive directly from the purchasers of
production all other Production Proceeds. In no case shall any failure, whether intentioned or
inadvertent, by Administrative Agent or Lenders to collect directly any such Production Proceeds
constitute in any way a waiver, remission or release of any of their rights under the Security
Documents, nor shall any release of any Production Proceeds by Administrative Agent or Lenders to
Restricted Persons constitute a waiver, remission, or release of any other Production Proceeds or
of any rights of Administrative Agent or Lenders to collect other Production Proceeds thereafter.
Until a Default has occurred, upon the written request of Borrower, Administrative Agent shall
notify any operator of Oil and Gas Properties of the Restricted Persons, that Administrative Agent
has not exercised its right to receive Production Proceeds attributable to such Oil and Gas
Properties and that Administrative Agent will notify such operator when it does exercise such
right.

Section 6.19. Perfection and Protection of Security Interests and Liens. Each Restricted
Person from time to time to deliver, to Administrative Agent any financing statements, continuation
statements, extension agreements, amendments to Security Documents, and other documents, properly
completed and executed (and acknowledged when required) by such Restricted Person in form and
substance satisfactory to Administrative Agent, which Administrative Agent requests for the purpose
of (i) perfecting, confirming, or protecting any Liens or other rights in Collateral securing any
Obligations and (ii) maintaining compliance with all applicable Laws, including those of any
applicable Indian tribe, the Bureau of Indian Affairs, and the U.S. Bureau of Land Management.
Each Restricted Person hereby authorizes Administrative Agent to file one or more financing or
continuation statements, and amendments thereto, relative to all or any part of the collateral
describing the Collateral as “all assets” without the signature of any Restricted Person.

Section 6.20. Mortgaged Property Covenants.

(a) Leases and Contracts; Performance of Obligations. Each Restricted Person will
maintain in full force and effect all oil, gas or mineral leases, contracts, servitudes and other
agreements forming a part of any Oil and Gas Property, to the extent the same cover or otherwise
relate to such Oil and Gas Property and to the extent such Oil and Gas Property is included in the
most recent Engineering Report, and each Restricted Person will timely perform all of its
obligations thereunder. Each Restricted Person will properly and timely pay all rents, royalties
and other payments due and payable under any such leases, contracts, servitudes and other
agreements, or under the Permitted Liens, or otherwise attendant to its ownership or operation of
any Oil and Gas Property. Each Restricted Person will promptly notify Administrative Agent of any
claim (or any conclusion by such Restricted Person) that such Restricted Person is obligated to
account for any royalties, or overriding royalties or other payments out of production, on a basis
(other than delivery in kind) less favorable to such Restricted Person than proceeds received by
Restricted Person (calculated at the well) from sale of production.

(b) Representation to Continue to be True. Each Restricted Person will carry out its
sales of production, will operate the Oil and Gas Properties, and will otherwise deal with the Oil
and Gas Properties and the production, in such a way that the representations and warranties in
Section 5.19 through 5.22 remain true and correct at, and as of, all times that this Agreement is
in effect (and not just at, and as of, the times such representations and warranties are made).

Section 6.21. Post-Closing Obligations. Borrower shall deliver to Administrative Agent,
within 90 days after the date of this Agreement, (i) charter documents of each Restricted Person
certified by the Secretary of State of its state of organization and (ii) a Certificate of
Existence and Good Standing of Petrosearch Energy Corporation from the Texas Secretary of State.

outstanding to Borrower, and to induce each Lender to enter into this Agreement and make the Loans,
Borrower warrants, covenants and agrees that until the full and final payment of the Obligations
and the termination of this Agreement (as determined without regard to unasserted indemnity

create, assume or permit to exist any Lien upon any of the properties or assets which it now owns

(a) contracts entered into with the purpose and effect of fixing prices on oil or gas
expected to be produced by Restricted Persons, provided that at all times: (i) no such contract
fixes a price for a period later than thirty-six (36) months after such contract is entered into,
(ii) the aggregate monthly production covered by all such contracts for any single month
(determined, in the case of contracts that are not settled on a monthly basis, by a monthly
proration acceptable to Administrative Agent) does not in the aggregate exceed (A) for contracts
that have a term of twelve (12) months or less, ninety percent (90%) of Restricted Persons’
aggregate Projected Oil and Gas Production anticipated (at the time such Hedging Contract is
entered into) to be sold in the ordinary course of the Restricted Persons’ businesses for such
month and (B) for contracts that have a term of more than twelve (12) months, but less than
thirty-six (36), eighty percent (80%) of Restricted Persons’ aggregate Projected Oil and Gas
Production anticipated (at the time such Hedging Contract is entered into) to be sold in the
ordinary course of the Restricted Persons’ businesses for such month, (iii) except for letters of
credit and the Collateral under the Security Documents with respect to Lender Hedging Obligations,

the event of its nonperformance prior to actual default by such Restricted Person in performing
its obligations thereunder, and (iv) each such contract is with a counterparty or has a guarantor
of the obligation of the counterparty who is a Lender or one of its Affiliates or an existing
counterparty listed in Schedule 5; and

interest rates on a principal amount of indebtedness of such Restricted Person that is accruing
interest at a variable rate, provided that (i) at the time such Hedging Contract is entered into,
the aggregate notional amount of such contracts does not exceed eighty percent (80%), excluding
puts, of the anticipated outstanding principal balance of the indebtedness to be hedged by such
contracts or an average of such principal balances calculated using a generally accepted method of
matching interest swap contracts to declining principal balances, (ii) the floating rate index of
each such contract generally matches the index used to determine the floating rates of interest on
the corresponding indebtedness to be hedged by such contract and (iii) each such contract is with
a counterparty or has a guarantor of the obligation of the counterparty who is a Lender or one of
its Affiliates.

(c) Notwithstanding the foregoing provisions of this Section 7.3, there shall be no
limitations on the purchase by the Restricted Persons of put options or floor transactions with
respect to oil or gas produced by Restricted Persons; provided, however, that any such put or
floor transaction shall be solely for hedging, and not for speculative purposes, and the
Restricted Person shall have no obligations thereunder other than payment of the applicable
premium for any such put or floor transaction.

(d) Borrower shall not cause or permit an early termination of any Hedging Contract on which
Administrative Agent and Lenders have relied in determining the Borrowing Base unless prior
approval is received from Administrative Agent.

that the rights of the Restricted Persons under Hedging Contracts with such Lender may be included
in the Collateral.

Section 7.5. Limitation on Mergers, Issuances of Securities. No Restricted Person will
merge or consolidate with or into any other Person except that any Subsidiary of Borrower may be
merged into or consolidated with (a) another Subsidiary of Borrower, so long as a Guarantor is the
surviving business entity, or (b) Borrower, so long as Borrower is the surviving business entity.
Borrower will not issue any securities other than (a) shares of its common stock, (b) shares of its
preferred stock which cannot be converted to Indebtedness prior to the Maturity Date or mandatorily
redeemed prior to the Maturity Date, and (c) any options or warrants giving the holders thereof
only the right to acquire common stock of Borrower. No Subsidiary of Borrower will issue any
additional shares of its Equity Interests or other securities or any options, warrants or other

extent not otherwise forbidden under the terms hereof. No Subsidiary of Borrower which is a
partnership will allow any diminution of Borrower’s interest (direct or indirect) therein.

Section 7.6. Limitation on Sales of Property. No Restricted Person will sell, transfer,

which is no longer used or useful in the conduct of its business or which is replaced by equipment
of equal suitability and value;

(b) inventory (including oil and gas sold as produced and seismic data) which is sold in the
ordinary course of business on ordinary trade terms;

(c) equity interests of any of Borrower’s Subsidiaries which are transferred to Borrower or a

aggregate sales price for all such property sold during any period of twelve (12) consecutive
calendar months shall not exceed five percent (5%) of the Present Value of the Borrowing Base

No Restricted Person will abandon or consent to the abandonment of, any oil or gas well
constituting Collateral so long as such well is capable (or is subject to being made capable
through drilling, reworking or other operations which it would be commercially feasible to conduct)
of producing oil, gas, or other hydrocarbons or other minerals in commercial quantities (as
determined without considering the effect of any Security Document). No Restricted Person will
elect not to participate in a proposed operation on any Oil and Gas Property constituting
Collateral where the effect of such election would be the forfeiture either temporarily (e.g.,
until a certain sum of money is received out of the forfeited interest) or permanently of any
interest in the Collateral unless such Restricted Person reasonably determines that the proposed
operation will not be economic.

Income; provided that no Default or Event of Default exists at the time such Distribution on common
stock is made or will occur as a result thereof; (c) Distributions due and payable with respect to
Borrower’s preferred stock; provided that so long as no Default or Event of Default exists at the
time such Distribution on preferred stock is made or will occur as a result thereof; and (d)

contributions to, or other Investments in any Person or property; provided that the Restricted
Persons (i) may make Permitted Investments (including Core Acquisitions and Investments), without
limitation, and (ii) may make Non-Core Acquisitions and Investments so long as the aggregate amount
expended on Non-Core Acquisitions and Investments during the period from the date hereof until the

Restricted Person will extend credit, make advances or make loans other than normal and prudent
extensions of credit to customers buying goods and services in the ordinary course of business,
which extensions shall not be for longer periods than those extended by similar businesses operated
in a normal and prudent manner.

Section 7.10. Transactions with Affiliates. Neither Borrower nor any of its Subsidiaries
nor any Guarantor will engage in any material transaction with any of its Affiliates on terms which
are less favorable to it than those which would have been obtainable at the time in arm’s-length
dealing with Persons other than such Affiliates, provided that such restriction shall not apply to
transactions among Borrower and its wholly owned Subsidiaries.

Section 7.11. Prohibited Contracts. Except as expressly provided for in the Loan
Documents, no Restricted Person will, directly or indirectly, enter into, create, or otherwise
allow to exist any contractual restriction or other consensual restriction on the ability of any
Subsidiary of Borrower to: (a) pay dividends or make other distributions to Borrower, (b) to redeem
equity interests held in it by Borrower, (c) to repay loans and other indebtedness owing by it to
Borrower, or (d) to transfer any of its assets to Borrower, except in the case of clause (d) for
(i) customary limitations and restrictions contained in, and limited to, specific leases, licenses,
conveyances, partnership agreements and co-owners’ agreements, and similar conveyances and
agreements (ii) customary restrictions on the assignment or transfer of any contract or agreement
that are contained in such contract or agreement, (iii) limitations and restrictions arising in
connection with Permitted Liens affecting only property subject to such Permitted Lien, (iv) any
restriction imposed on particular assets or properties pursuant to an agreement entered into for a
sale of such assets or properties not prohibited by Section 7.5 of this Agreement pending the
closing of such sale, and (v) limitations and restrictions airing or existing by reason of
applicable law. No Restricted Person will enter into any “take-or-pay” contract or other contract
or arrangement for the purchase of goods or services which obligates it to pay for such goods or
service regardless of whether they are delivered or furnished to it. No Restricted Person will
amend or permit any amendment to any contract or lease which releases, qualifies, limits, makes
contingent or otherwise detrimentally affects the rights and benefits of Administrative Agent or
any Lender under or acquired pursuant to any Security Documents. No ERISA Affiliate will incur any
obligation to contribute to any “multiemployer plan” as defined in Section 4001 of ERISA.

ratio of (a) Consolidated Funded Debt as of the end of such Fiscal Quarter to (b) Adjusted
Consolidated EBITDAX for the period of twelve consecutive calendar months then ended shall never be

payment becomes due and payable or as a result of acceleration or otherwise;

(b) Any Restricted Person fails to pay any Obligation (other than the Obligations in

agreement or provision of Section 6.4 or Article VII;

(e) Any Restricted Person fails (other than as referred to in subsections (a), (b), (c) or

thirty (30) days after notice of such failure is given by Administrative Agent to Borrower;

(f) Any representation or warranty previously, presently or hereafter made in writing by or
on behalf of any Restricted Person in connection with any Loan Document shall prove to have been

any reason other than its release or subordination by Administrative Agent;

(g) Any Restricted Person fails to duly observe, perform or comply with any agreement with
any Person or any term or condition of any instrument, if such agreement or instrument is

(h) Any Restricted Person (i) fails to pay any portion, when such portion is due, of any of
its Indebtedness in excess of the Threshold Amount, or (ii) breaches or defaults in the
performance of any agreement or instrument by which any such Indebtedness is issued, evidenced,
governed, or secured, and any such failure, breach or default continues beyond any applicable
period of grace provided therefor; provided, however, that an Event of Default shall not occur
under this subsection (h) if the default is a failure to pay caused by an error or omission of an
administrative or operational nature and funds were available to the Restricted Person to make the
relevant payment when due and such payment is in fact made on or before the third Business Day
following receipt of notice for the other party of such failure to pay;

(i) Either (i) any “accumulated funding deficiency” (as defined in Section 412(a) of the

involving the withdrawal of a substantial employer, the withdrawing employer’s proportionate share
of such excess exceeds such amount);

(j) Any Restricted Person:

(i) suffers the entry against it of a judgment, decree or order for relief by a

any time consented to, requested by, or acquiesced to by it; or

(iv) suffers the entry against it of one or more final judgments or orders for the
payment of money in an aggregate amount (as to all such judgments or orders) in excess of

discretion), unless the same is discharged within thirty days after the date of entry
thereof or an appeal or appropriate proceeding for review thereof is taken within such
period and a stay of execution pending such appeal is obtained; or

(v) suffers a writ or warrant of attachment or any similar process to be issued by any
Tribunal against all or any substantial part of its assets or any part of the Collateral,
and such writ or warrant of attachment or any similar process is not stayed or released

aside; and

(k) any Material Adverse Change occurs.

Upon the occurrence of an Event of Default described in subsection (j)(i), (j)(ii) or (j)(iii) of
this section with respect to any Restricted Person, all of the Obligations shall thereupon be
immediately due and payable, without demand, presentment, notice of demand or of dishonor and
nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are hereby expressly
waived by Borrower and each Restricted Person who at any time ratifies or approves this Agreement.
Upon any such acceleration, any obligation of any Lender to make any further Loans and any
obligation of LC Issuer to issue Letters of Credit hereunder shall be permanently terminated.
During the continuance of any other Event of Default, Administrative Agent at any time and from
time to time may (and upon written instructions from Required Lenders, Administrative Agent shall),

demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest,
notice of intention to accelerate, declaration or notice of acceleration, or any other notice or
declaration of any kind, all of which are hereby expressly waived by Borrower and each Restricted
Person who at any time ratifies or approves this Agreement.

Section 8.2. Remedies. If any Default shall occur and be continuing, Required Lenders, or
Administrative Agent at the direction of Required Lenders, may protect and enforce its rights under
the Loan Documents by any appropriate proceedings, including proceedings for specific performance
of any covenant or agreement contained in any Loan Document. All rights, remedies and powers
conferred upon Lender Parties under the Loan Documents shall be deemed cumulative and not exclusive
of any other rights, remedies or powers available under the Loan Documents or at Law or in equity.

Section 8.3. Application of Proceeds After Acceleration. After the exercise of remedies
provided for in Section 8.2 (or after the Loans have automatically become immediately due and
payable and the L/C Obligations have automatically been required to be cash collateralized as set
forth in Section 2.13), any amounts received on account of the Secured Obligations shall be applied
by Agent in the following order:

First, to payment of that portion of the Obligations constituting fees,
indemnities, expenses and other amounts (including fees, charges and disbursements of
counsel to Agent (including fees and time charges for attorneys who may be employees of
Agent) and amounts payable under Article III) payable to Agent in its capacity as
such;

Second, to payment of that portion of the Obligations constituting fees,
indemnities and other amounts (other than principal, interest and L/C Fees) payable to
Lenders, the L/C Issuer and Lender Counterparties (including fees, charges and disbursements
of counsel to the respective Lenders and the L/C Issuer and amounts payable under
Article III), ratably among them in proportion to the respective amounts described
in this clause Second payable to them and the Lenders;

Third, to payment of that portion of the Secured Obligations constituting
accrued and unpaid L/C Fees and interest on the Loans, the L/C Borrowings and the Lender
Hedging Obligations, ratably among Lenders, L/C Issuer and the Lender Counterparties, in
proportion to the respective amounts described in this clause Third payable to them;

Fourth, to payment of that portion of the Secured Obligations constituting
unpaid principal of the Loans and L/C Borrowings, obligations to deliver cash collateral for
L/C Obligations pursuant to Section 2.13 and settlements under Hedging Contracts, ratably
among Lenders, the L/C Issuer and the Lender Counterparties in proportion to the respective
amounts described in this clause Fourth held by them; and

Last, the balance, if any, after all of the Secured Obligations have been
indefeasibly paid in full, to Borrower or as otherwise required by Law.

Subject to Section 2.12, amounts used to cash collateralize the aggregate undrawn amount of Letters
of Credit pursuant to clause Fourth above shall be applied to satisfy drawings under such
Letters of Credit as they occur. If any amount remains on deposit as cash collateral after all
Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied
to the other Secured Obligations, if any, in the order set forth above.

Administrative Agent shall have no responsibility to determine the existence or amount of Lender
Hedging Obligations and may reserve from the application of amounts under this Section amounts
distributable in respect of Lender Hedging Obligations until it has received evidence satisfactory
to it of the existence and amount of such Lender Hedging Obligations.

ARTICLE IX — Administrative Agent

Section 9.1. Appointment and Authority. Each of the Lenders and LC Issuer hereby
irrevocably appoints Bank of Oklahoma, N.A. to act on its behalf as Administrative Agent hereunder
and under the other Loan Documents and authorizes Administrative Agent to take such actions on its
behalf and to exercise such powers as are delegated to Administrative Agent by the terms hereof or
thereof, together with such actions and powers as are reasonably incidental thereto. The
provisions of this Article are solely for the benefit of Administrative Agent, the Lenders and LC
Issuer, and neither Borrower nor any other Restricted Person shall have rights as a third party
beneficiary of any of such provisions.

Section 9.2. Exculpatory Provisions. Administrative Agent shall not have any duties or
obligations except those expressly set forth herein and in the other Loan Documents. Without
limiting the generality of the foregoing, Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a
Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan
Documents that Administrative Agent is required to exercise as directed in writing by the Required
Lenders (or such other number or percentage of Lenders as shall be expressly provided for herein
or in the other Loan Documents), provided that Administrative Agent shall not be required
to take any action that, in its opinion or the opinion of its counsel, may expose Administrative
Agent to liability or that is contrary to any Loan Document or applicable law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any
duty to disclose, and shall not be liable for the failure to disclose, any information relating to
Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as
Administrative Agent or any of its Affiliates in any capacity.

Administrative Agent shall not be liable for any action taken or not taken by it (i) with the
consent or at the request of Required Lenders (or such other number or percentage of the Lenders as
shall be necessary, or as Administrative Agent shall believe in good faith shall be necessary,
under the circumstances as provided in Sections 10.1 and 8.2) or (ii) in the absence of its own
gross negligence or willful misconduct. Administrative Agent shall be deemed not to have knowledge
of any Default unless and until notice describing such Default is given to Administrative Agent by
Borrower, a Lender or LC Issuer.

Administrative Agent shall not be responsible for or have any duty to ascertain or inquire
into (i) any statement, warranty or representation made in or in connection with this Agreement or
any other Loan Document, (ii) the contents of any certificate, report or other document delivered
hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance
of any of the covenants, agreements or other terms or conditions set forth herein or therein or the
occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Loan Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to Administrative Agent.

Section 9.3. Reliance by Administrative Agent. Administrative Agent shall be entitled to
rely upon, and shall not incur any liability for relying upon, any notice, request, certificate,
consent, statement, instrument, document or other writing (including any electronic message,
Internet or intranet website posting or other distribution) believed by it to be genuine and to
have been signed, sent or otherwise authenticated by the proper Person. Administrative Agent also
may rely upon any statement made to it orally or by telephone and believed by it to have been made
by the proper Person, and shall not incur any liability for relying thereon. In determining
compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of
Credit, that by its terms must be fulfilled to the satisfaction of a Lender or LC Issuer,
Administrative Agent may presume that such condition is satisfactory to such Lender or LC Issuer
unless Administrative Agent shall have received notice to the contrary from such Lender or LC
Issuer prior to the making of such Loan or the issuance of such Letter of Credit. Administrative
Agent may consult with legal counsel (who may be counsel for Borrower), independent accountants and
other experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts.

Section 9.4. Non-Reliance on Administrative Agent and Other Lenders. Each Lender and LC
Issuer acknowledges that it has, independently and without reliance upon Administrative Agent or
any other Lender or any of their Related Parties and based on such documents and information as it
has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.
Each Lender and LC Issuer also acknowledges that it will, independently and without reliance upon
Administrative Agent or any other Lender or any of their Related Parties and based on such
documents and information as it shall from time to time deem appropriate, continue to make its own
decisions in taking or not taking action under or based upon this Agreement, any other Loan
Document or any related agreement or any document furnished hereunder or thereunder.

Section 9.5. Rights as a Lender. The Person serving as Administrative Agent hereunder
shall have the same rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not Administrative Agent and the term “Lender” or “Lenders”
shall, unless otherwise expressly indicated or unless the context otherwise requires, include the
Person serving as Administrative Agent hereunder in its individual capacity. Such Person and its
Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other
advisory capacity for and generally engage in any kind of business with Borrower or any Subsidiary
or other Affiliate thereof as if such Person were not Administrative Agent hereunder and without
any duty to account therefor to the Lenders.

Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it
shall, whether through the exercise of rights under Security Documents or rights of banker’s lien,
set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the
aggregate Obligations owed to it, taking into account all distributions made by Administrative
Agent under Section 3.1, and such payment causes such Lender Party to have received more than it
would have received had such payment been received by Administrative Agent and distributed pursuant
to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated
to purchase interests in the Obligations as necessary to cause all Lender Parties to share all
payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to
time as shall be equitable to ensure that Administrative Agent and all Lender Parties share all
payments of Obligations as provided in Section 3.1; provided, however, that nothing herein
contained shall in any way affect the right of any Lender Party to obtain payment (whether by
exercise of rights of banker’s lien, set-off or counterclaim or otherwise) of indebtedness other
than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that
any holder of any such interest or other participation in the Obligations, whether or not acquired
pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and
all rights of banker’s lien, set-off, or counterclaim as fully as if such holder were a holder of
the Obligations in the amount of such interest or other participation. If all or any part of any
funds transferred pursuant to this section is thereafter recovered from the seller under this
section which received the same, the purchase provided for in this section shall be deemed to have
been rescinded to the extent of such recovery, together with interest, if any, if interest is
required pursuant to the order of a Tribunal order to be paid on account of the possession of such
funds prior to such recovery.

Section 9.7. Investments. Whenever Administrative Agent in good faith determines that it
is uncertain about how to distribute to Lender Parties any funds which it has received, or whenever
Administrative Agent in good faith determines that there is any dispute among Lender Parties about
how such funds should be distributed, Administrative Agent may choose to defer distribution of the
funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith
believes that the uncertainty or dispute will not be promptly resolved, or if Administrative Agent
is otherwise required to invest funds pending distribution to Lender Parties, Administrative Agent
shall invest such funds pending distribution; all interest on any such Investment shall be
distributed upon the distribution of such Investment and in the same proportion and to the same
Persons as such Investment. All moneys received by Administrative Agent for distribution to Lender
Parties (other than to the Person who is Administrative Agent in its separate capacity as a Lender
Party) shall be held by Administrative Agent pending such distribution solely as Administrative
Agent for such Lender Parties, and Administrative Agent shall have no equitable title to any
portion thereof.

Section 9.8. Resignation of Administrative Agent. Administrative Agent may at any time
give notice of its resignation to the Lenders, LC Issuer and Borrower. Upon receipt of any such
notice of resignation, Required Lenders shall have the right, in consultation with Borrower, to
appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of
any such bank with an office in the United States. If no such successor shall have been so
appointed by Required Lenders and shall have accepted such appointment within 30 days after the
retiring Administrative Agent gives notice of its resignation, then the retiring Administrative
Agent may on behalf of the Lenders and LC Issuer, appoint a successor Administrative Agent meeting
the qualifications set forth above provided that if Administrative Agent shall notify Borrower and
the Lenders that no qualifying Person has accepted such appointment, then such resignation shall
nonetheless become effective in accordance with such notice and (1) the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder and under the other Loan
Documents (except that in the case of any Collateral held by Administrative Agent on behalf of the
Lenders or LC Issuer under any of the Loan Documents, the retiring Administrative Agent shall
continue to hold such Collateral until such time as a successor Administrative Agent is appointed)
and (2) all payments, communications and determinations provided to be made by, to or through
Administrative Agent shall instead be made by or to each Lender and LC Issuer directly, until such
time as Required Lenders appoint a successor Administrative Agent as provided for above in this
Section. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such
successor shall succeed to and become vested with all of the rights, powers, privileges and duties
of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be
discharged from all of its duties and obligations hereunder or under the other Loan Documents (if
not already discharged therefrom as provided above in this Section). The fees payable by Borrower
to a successor Administrative Agent shall be the same as those payable to its predecessor unless
otherwise agreed between Borrower and such successor. After the retiring Administrative Agent’s
resignation hereunder and under the other Loan Documents, the provisions of this Article and
Section 10.4 shall continue in effect for the benefit of such retiring Administrative Agent, its
sub-agents and their respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

Section 9.9. Delegation of Duties. Administrative Agent may perform any and all of its
duties and exercise its rights and powers hereunder or under any other Loan Document by or through
any one or more sub-agents appointed by Administrative Agent. Administrative Agent and any such
sub-agent may perform any and all of its duties and exercise its rights and powers by or through
their respective Related Parties. The exculpatory provisions of this Article shall apply to any
such sub-agent and to the Related Parties of Administrative Agent and any such sub-agent, and shall
apply to their respective activities in connection with the syndication of the credit facilities
provided for herein as well as activities as Administrative Agent.

Section 9.10. Administrative Agent May File Proofs of Claim. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to any Restricted Person, Administrative Agent
(irrespective of whether the principal of any Loan or LC Obligation shall then be due and payable
as herein expressed or by declaration or otherwise and irrespective of whether Administrative Agent
shall have made any demand on Borrower) shall be entitled and empowered, by intervention in such
proceeding or otherwise

(a) to file and prove a claim for the whole amount of the principal and interest owing
and unpaid in respect of the Loans, LC Obligations and all other Obligations that are owing
and unpaid and to file such other documents as may be necessary or advisable in order to
have the claims of Lenders, the LC Issuer and Administrative Agent (including any claim for
the reasonable compensation, expenses, disbursements and advances of Lenders, the LC Issuer
and Administrative Agent and their respective agents and counsel and all other amounts due
Lenders, the LC Issuer and Administrative Agent under Section 2.5 and 10.04) allowed in such
judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any
such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender and the LC Issuer to make such
payments to Administrative Agent and, in the event that Administrative Agent shall consent to the
making of such payments directly to Lenders and the LC Issuer, to pay to Administrative Agent any
amount due for the reasonable compensation, expenses, disbursements and advances of Administrative
Agent and its agents and counsel, and any other amounts due Administrative Agent under Sections 2.5
and 10.4. Nothing contained herein shall be deemed to authorize Administrative Agent to authorize
or consent to or accept or adopt on behalf of any Lender or the LC Issuer any plan of
reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of
any Lender or to authorize Administrative Agent to vote in respect of the claim of any Lender in
any such proceeding.

Section 9.11. Guaranty Matters. Each Lender and the LC Issuer hereby irrevocably
authorizes Administrative Agent, at its option and in its discretion, to release any Guarantor from
its obligations under the Guaranty (i) if such Person ceases to be a Subsidiary as a result of a
transaction permitted hereunder and (ii) upon termination of each Lender’s Commitment and payment
in full of all Obligations (other than contingent indemnification obligations) and the expiration
or termination of all Letters of Credit. Upon request by Administrative Agent at any time, each
Lender and the LC Issuer will confirm in writing Administrative Agent’s authority to release any
Guarantor from its obligations under the Subsidiary Guaranty pursuant to this Section 9.12.

Section 9.12. Collateral Matters. 

(a) Each Lender and the LC Issuer hereby irrevocably authorizes and directs Administrative
Agent to enter into the Security Documents for the benefit of such Lender and the LC Issuer. Each
Lender and the LC Issuer hereby agrees, and each holder of any Note by the acceptance thereof will
be deemed to agree, that, except as otherwise set forth in Section 10.1, any action taken by the
Required Lenders, in accordance with the provisions of this Agreement or the Security Documents,
and the exercise by the Required Lenders of the powers set forth herein or therein, together with
such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of
Lenders and the LC Issuer. Administrative Agent is hereby authorized (but not obligated) on behalf
of all of Lenders and the LC Issuer, without the necessity of any notice to or further consent from
any Lender or the LC Issuer from time to time prior to, an Event of Default, to take any action
with respect to any Collateral or Security Documents which may be necessary to perfect and maintain
perfected the Liens upon the Collateral granted pursuant to the Security Documents.

(b) Each Lender and the LC issuer hereby irrevocably authorize Administrative Agent, at its
option and in its discretion,

(i) to release any Lien on any property granted to or held by Administrative Agent
under any Loan Document (A) upon termination of each Lender’s Commitment and payment in full
of all Obligations (other than contingent indemnification obligations) and the expiration or
termination of all Letters of Credit, (B) that is sold or to be sold as part of or in
connection with any sale permitted hereunder or under any other Loan Document, (C) subject
to Section 10.01, if approved, authorized or ratified in writing by the Required
Lenders, or (D) in connection with any foreclosure sale or other disposition of Collateral
after the occurrence of an Event of Default; and

(ii) to subordinate any Lien on any property granted to or held by Administrative Agent
under any Loan Document to the holder of any Lien on such property that is permitted by this
Agreement or any other Loan Document.

Upon request by Administrative Agent at any time, each Lender and the LC Issuer will confirm
in writing Administrative Agent’s authority to release or subordinate its interest in particular
types or items of Collateral pursuant to this Section 9.12.

(c) Subject to (b) above, Administrative Agent shall (and is hereby irrevocably authorized by
each Lender and the LC Issuer , to execute such documents as may be necessary to evidence the
release or subordination of the Liens granted to Administrative Agent for the benefit of
Administrative Agent and Lenders and the LC Issuer herein or pursuant hereto upon the applicable
Collateral; provided that (i) Administrative Agent shall not be required to execute any such
document on terms which, in Administrative Agent’s opinion, would expose Administrative Agent to or
create any liability or entail any consequence other than the release or subordination of such
Liens without recourse or warranty and (ii) such release or subordination shall not in any manner
discharge, affect or impair the Obligations or any Liens upon (or obligations of Borrower or any
other Restricted Person in respect of) all interests retained by Borrower or any other Restricted
Person, including the proceeds of the sale, all of which shall continue to constitute part of the
Collateral. In the event of any sale or transfer of Collateral, or any foreclosure with respect to
any of the Collateral, Administrative Agent shall be authorized to deduct all expenses reasonably
incurred by Administrative Agent from the proceeds of any such sale, transfer or foreclosure.

(d) Administrative Agent shall have no obligation whatsoever to any Lender, the LC Issuer or
any other Person to assure that the Collateral exists or is owned by Borrower or any other
Restricted Person or is cared for, protected or insured or that the Liens granted to Administrative
Agent herein or in any of the Security Documents or pursuant hereto or thereto have been properly
or sufficiently or lawfully created, perfected, protected or enforced or are entitled to any
particular priority, or to exercise or to continue exercising at all or in any manner or under any
duty of care, disclosure or fidelity any of the rights, authorities and powers granted or available
to Administrative Agent in this Section 9.12 or in any of the Security Documents, it being
understood and agreed that in respect of the Collateral, or any act, omission or event related
thereto, Administrative Agent may act in any manner it may deem appropriate, in its sole
discretion, given Administrative Agent’s own interest in the Collateral as one of Lenders and that
Administrative Agent shall have no duty or liability whatsoever to Lenders or the LC Issuer.

(e) Each Lender and the LC Issuer hereby appoints each other Lender as agent for the purpose
of perfecting Lenders’ and the LC Issuer’s security interest in assets which, in accordance with
Article 9 of the UCC can be perfected only by possession. Should any Lender or the LC Issuer
(other than Administrative Agent) obtain possession of any such Collateral, such Lender or the LC
Issuer shall notify Administrative Agent thereof, and, promptly upon Administrative Agent’s request
therefor shall deliver such Collateral to Administrative Agent or in accordance with Administrative
Agent’s instructions.

Section 9.13. Agreement to Assignment of ISDA Master Agreement. Each Lender hereby
agrees (on behalf of itself and any of its Affiliates party to Hedging Contract with any
Restricted Person) that the rights of the Restricted Persons under Hedging Contracts with such
Lender (or, if applicable, its Affiliate) may be included in the Collateral.

Section 9.14. No Other Duties, etc. Anything herein to the contrary notwithstanding,
the “Documentation Agent” listed on the cover page hereof shall not have any powers, duties or
responsibilities under this Agreement or any of the other Loan Documents, except in its capacity,
as applicable, as a Lender or LC Issuer hereunder.

	 	Waivers and Amendments; Acknowledgments.
	
 
	 	 

(a) Waivers and Amendments. No failure or delay (whether by course of conduct or
otherwise) by any Lender in exercising any right, power or remedy which such Lender Party may have
under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or
remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or
remedy preclude any other or further exercise thereof or of any other right, power or remedy. No
waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever
be effective unless it is in writing and signed as provided below in this section, and then such
waiver or consent shall be effective only in the specific instances and for the purposes for which

of the conditions specified in Article IV (provided that Administrative Agent may in its
discretion withdraw any request it has made under Section 4.2(f)), (2) increase the maximum amount
which such Lender is committed hereunder to lend, (3) reduce any fees payable to such Lender

of such payment, (7) release all or substantially all of the Collateral, except for such releases
relating to sales or dispositions of property permitted by the Loan Documents, or (8) amend this
Section 10.1(a). Notwithstanding the foregoing, no Impacted Lender shall have the right to vote

provision of any Loan Document, release any Collateral or to direct the actions of Administrative
Agent.

(b) Acknowledgments and Admissions. Borrower hereby represents, warrants,
acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and
delivery of the Loan Documents to which it is a party, (ii) it has made an independent decision to

warranties, covenants, undertakings or agreements by any Lender as to the Loan Documents except as

hereof, (iv) no Lender has any fiduciary obligation toward Borrower with respect to any Loan
Document or the transactions contemplated thereby, (v) the relationship pursuant to the Loan
Documents between Borrower and the other Restricted Persons, on one hand, and each Lender, on the
other hand, is and shall be solely that of debtor and creditor, respectively, provided that,
solely for purposes of Section 10.5(c) Administrative Agent shall act as agent of Borrower in
maintaining the Register as set forth therein, (vi) no partnership or joint venture exists with
respect to the Loan Documents between any Restricted Person and any Lender, (vii) Administrative
Agent is not Borrower’s Administrative Agent, but Administrative Agent for Lenders, provided that,
solely for purposes of Section 10.5(c) Administrative Agent shall act as agent of Borrower in
maintaining the Register as set forth therein, (viii) should an Event of Default or Default occur
or exist, each Lender will determine in its sole discretion and for its own reasons what remedies
and actions it will or will not exercise or take at that time, (ix) without limiting any of the
foregoing, Borrower is not relying upon any representation or covenant by any Lender, or any
representative thereof, and no such representation or covenant has been made, that any Lender
will, at the time of an Event of Default or Default, or at any other time, waive, negotiate,
discuss, or take or refrain from taking any action permitted under the Loan Documents with respect
to any such Event of Default or Default or any other provision of the Loan Documents, and (x) all
Lender Parties have relied upon the truthfulness of the acknowledgments in this section in
deciding to execute and deliver this Agreement and to become obligated hereunder.

represent the final agreement between the parties and may not be contradicted by evidence of prior,
contemporaneous, or subsequent oral agreements of the parties.

There are no unwritten oral agreements between the parties.

Section 10.2. Survival of Agreements; Cumulative Nature. All of Restricted Persons’
various representations, warranties, covenants and agreements in the Loan Documents shall survive
the execution and delivery of this Agreement and the other Loan Documents and the performance
hereof and thereof, including the making or granting of the Loans and the delivery of the Notes
and the other Loan Documents, and shall further survive until all of the Obligations are paid in
full to each Lender Party and all of Lender Parties’ obligations to Borrower are terminated.
Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by
any Restricted Person in any Loan Document, any Obligations under Sections 3.2 through Section 3.6,
and any obligations which any Person may have to indemnify or compensate any Lender Party shall
survive any termination of this Agreement or any other Loan Document. In addition, Articles VIII
and IX shall survive until all of the Security Documents have been terminated. All statements and
agreements contained in any certificate or other instrument delivered by any Restricted Person to
any Lender Party under any Loan Document shall be deemed representations and warranties by Borrower
or agreements and covenants of Borrower under this Agreement. The representations, warranties,
indemnities, and covenants made by Restricted Persons in the Loan Documents, and the rights,
powers, and privileges granted to Lender Parties in the Loan Documents, are cumulative, and, except
for expressly specified waivers and consents, no Loan Document shall be construed in the context of
another to diminish, nullify, or otherwise reduce the benefit to any Lender Party of any such
representation, warranty, indemnity, covenant, right, power or privilege. In particular and
without limitation, no exception set out in this Agreement to any representation, warranty,
indemnity, or covenant herein contained shall apply to any similar representation, warranty,
indemnity, or covenant contained in any other Loan Document, and each such similar representation,
warranty, indemnity, or covenant shall be subject only to those exceptions which are expressly made
applicable to it by the terms of the various Loan Documents.

disbursements of counsel for Administrative Agent), in connection with the syndication of the

administration of this Agreement and the other Loan Documents or any amendments, modifications or
waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby
or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by LC Issuer

negotiations in respect of such Loans or Letters of Credit.

(b) Indemnification by Borrower. Borrower shall indemnify Administrative Agent (and
any sub-agent thereof), each Lender and LC Issuer, and each Related Party of any of the foregoing
Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related expenses (including
the fees, charges and disbursements of any counsel for any Indemnitee), incurred by any Indemnitee
or asserted against any Indemnitee by any third party or by Borrower or any other Restricted
Person arising out of, in connection with, or as a result of (i) the execution or delivery of this
Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby,
the performance by the parties hereto of their respective obligations hereunder or thereunder or
the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or Letter of

proceeding relating to any of the foregoing, whether based on contract, tort or any other theory,
whether brought by a third party or by Borrower or any other LC Issuer, and regardless of whether
any Indemnitee is a party thereto. THE FOREGOING INDEMNIFICATION WILL APPLY WHETHER OR NOT SUCH
LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF
ANY KIND BY ANY INDEMNITEE, provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or related expenses (x) are
determined by a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a
claim brought by Borrower or any other Restricted Person against an Indemnitee for breach in bad
faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if Borrower or
such Restricted Person has obtained a final and nonappealable judgment in its favor on such claim
as determined by a court of competent jurisdiction.

(c) Reimbursement by Lenders. To the extent that Borrower for any reason fails to
indefeasibly pay any amount required under paragraph (a) or (b) of this Section to be paid by it
to Administrative Agent (or any sub-agent thereof), LC Issuer or any Related Party of any of the
foregoing, each Lender severally agrees to pay to Administrative Agent (or any such sub-agent), LC
Issuer or such Related Party, as the case may be, such Lender’s Percentage Share (determined as of
the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid
amount, provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted against
Administrative Agent (or any such sub-agent) or LC Issuer in its capacity as such, or against any
Related Party of any of the foregoing acting for Administrative Agent (or any such sub-agent) or
LC Issuer in connection with such capacity. The obligations of the Lenders under this paragraph
(c) are subject to the provisions of Section 2.17.

(d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on
any theory of liability, for special, indirect, consequential or punitive damages (as opposed to
direct or actual damages) arising out of, in connection with, or as a result of, this Agreement,
any other Loan Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof.
No Indemnitee referred to in paragraph (b) above shall be liable for any damages arising from the

Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(e) Payments. All amounts due under this Section shall be payable not later than ten
(10) days after demand therefor.

Section 10.5. Successors and Assigns; Joint and Several Liability.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that neither Borrower nor any other Restricted Person may assign
or otherwise transfer any of its rights or obligations under any Loan Document without the prior
written consent of Administrative Agent and each Lender and no Lender may assign or otherwise
transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in
accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in
accordance with the provisions of subsection (d) of this Section or (iii) by way of pledge or
assignment of a security interest subject to the restrictions of subsection (f) of this Section
(and any other attempted assignment or transfer by any party hereto shall be null and void).
Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person
(other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in subsection (d) of this Section and, to the extent expressly
contemplated hereby, the Related Parties of each of Administrative Agent and the Lenders) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this Agreement and the
other Loan Documents (including all or a portion of its Commitment and the Loans at the time owing
to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning
Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to
a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the
aggregate amount of the Commitment (which for this purpose includes Loans outstanding
thereunder) or, if the applicable Commitment is not then in effect, the principal
outstanding balance of the Loans of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such assignment is
delivered to Administrative Agent or, if “Trade Date” is specified in the Assignment and
Assumption, as of the Trade Date) shall not be less than $5,000,000, in the case of any
assignment in respect of a revolving facility, or $1,000,000, in the case of any assignment
in respect of a term facility, unless each of Administrative Agent and, so long as no
Default has occurred and is continuing, Borrower otherwise consent (each such consent not to
be unreasonably withheld or delayed);

(ii) each partial assignment shall be made as an assignment of a proportionate part of
all the assigning Lender’s rights and obligations under this Agreement with respect to the
Loan or the Commitment assigned;

(iii) any assignment of a Commitment must be approved by Administrative Agent and LC
Issuer unless the Person that is the proposed assignee is itself a Lender with a Commitment
(whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

(iv) the parties to each assignment shall execute and deliver to Administrative Agent
an Assignment and Assumption, together with the Note subject to such assignment and a
processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a
Lender, shall deliver to Administrative Agent an Administrative Questionnaire in form
satisfactory to Administrative Agent.

Subject to acceptance and recording thereof by Administrative Agent pursuant to subsection (c) of
this Section, from and after the effective date specified in each Assignment and Assumption, the
Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits, and subject to the requirements of Sections 3.2, 3.4, 3.5 and 10.4 with
respect to facts and circumstances occurring prior to the effective date of such assignment. Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this subsection shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with subsection (d) of this
Section.

(c) Participations. Any Lender may at any time, without the consent of, or notice
to, Borrower or Administrative Agent, sell participations to any Person (other than a natural
person or Borrower or any of Borrower’s Affiliates or Subsidiaries) (each, a
“Participant”) in all or a portion of such Lender’s rights and/or obligations under this
Agreement (including all or a portion of its commitment and/or the Loans owing to it);
provided that (i) such Lender’s obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for the performance
of such obligations and (iii) Borrower, Administrative Agent and the Lenders and LC Issuer shall
continue to deal solely and directly with such Lender in connection with such Lender’s rights and
obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the fifth sentence of
Section 10.1(a) that affects such Participant. Subject to subsection (e) of this Section, the
Borrower agrees that each Participant shall be entitled to the benefits of, and subject to the
requirements of, Sections 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to subsection (b) of this Section. To the extent
permitted by law, each Participant also shall be entitled to the benefits of Section 6.14 as though
it were a Lender, provided such Participant agrees to be subject to Section 9.6 as though
it were a Lender.

(d) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Sections 3.2 and 3.5 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with the Borrower’s prior written consent. A
Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 3.5 unless the Borrower is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section
3.5(e) as though it were a Lender.

(e) Certain Pledges. Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations of such Lender,
including any pledge or assignment to secure obligations to a Federal Reserve Bank;
provided that no such pledge or assignment shall release such Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

(f) Joint and Several Liability. All Obligations which are incurred by two or more
Restricted Persons shall be their joint and several obligations and liabilities.

Section 10.6. Confidentiality. Each of Administrative Agent, the Lenders and LC Issuer
agrees to maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective
partners, directors, officers, employees, agents, advisors and other representatives (it being
understood that the Persons to whom such disclosure is made will be informed of the confidential
nature of such Information and instructed to keep such Information confidential), (b) to the extent
requested by any regulatory authority purporting to have jurisdiction over it (including any
self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the
extent required by applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under
any other Loan Document or any action or proceeding relating to this Agreement or any other Loan
Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap
or derivative transaction relating to Borrower and its obligations, (g) with the consent of
Borrower or (h) to the extent such Information (x) becomes publicly available other than as a
result of a breach of this Section or (y) becomes available to Administrative Agent, any Lender, LC
Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than
the Borrower.

For purposes of this Section, “Information” means all information received from
Borrower or any of its Subsidiaries relating to Borrower or any of its Subsidiaries or any of their
respective businesses, other than any such information that is available to Administrative Agent,
any Lender or LC Issuer on a nonconfidential basis prior to disclosure by Borrower or any of its
Subsidiaries, provided that, in the case of information received from Borrower or any of
its Subsidiaries after the date hereof, such information is clearly identified at the time of
delivery as confidential. Any Person required to maintain the confidentiality of Information as
provided in this Section shall be considered to have complied with its obligation to do so if such
Person has exercised the same degree of care to maintain the confidentiality of such Information as
such Person would accord to its own confidential information.

the subject matter hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof. Except as provided in Section 4.1, this Agreement
