are received from the Lenders, the Administrative Agent shall make such funds available to the
Borrower by wire transfer to the accounts the Borrower shall have specified in its Borrowing
Request. The failure of any Lender to make any Loan required to be made by it shall not relieve
any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are

required.

delivery of a Continuation/Conversion Notice with respect to any Eurodollar Loan at least three (3)
Business Days before the last day of the then current Interest Period with respect thereto, such
Eurodollar Loan shall, on such last day, automatically convert to a Base Rate Loan); provided,

outstanding Loans of all Lenders to the Borrower, and (ii) no portion of the outstanding principal
amount of any Loans may be so continued as, or be so converted into, Eurodollar Loans when any

make, continue or convert Eurodollar Loans hereunder by causing a domestic or foreign branch or an
Affiliate (or an international banking facility created by such Lender) to make or maintain such
Eurodollar Loan; provided, however, that such Eurodollar Loan shall nonetheless be deemed to have
been made and to be held by such Lender, and the obligations of the Borrower to repay such
Eurodollar Loan shall nevertheless be to such Lender for the account of such foreign branch,
Affiliate or international banking facility.

     SECTION 2.6. Notes. Each Lender’s Loans under its Commitment shall be evidenced by a
Note payable to the order of such Lender in a maximum principal amount equal to such Lender’s
Percentage of the Commitments. The Borrower hereby irrevocably authorizes each Lender to make (or
cause to be made) appropriate notations on the grid attached to such Lender’s Note (or on any
continuation of such grid or otherwise in its records), which notations, if made, shall evidence,
inter alia, the date of, the outstanding principal of, and the interest rate and
Interest Period applicable to the Loans evidenced thereby. Such notations shall be conclusive and
binding on the Borrower absent manifest error; provided, however, that the failure of any Lender to
make any such notations shall not limit or otherwise affect any Obligations of the Borrower or any
other Obligor.

ARTICLE III

REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

     SECTION 3.1. Repayments and Prepayments. The Borrower shall repay in full the unpaid
principal amount of each Loan upon the Revolving Credit Termination Date. Prior thereto, the
Borrower:

     (a) may not make any voluntary prepayment of the Loans that would reduce the
outstanding principal balance thereof to less than $150,000,000;

     (b) shall, on each date when (i) any reduction in or termination of the Commitments
shall become effective or (ii) the outstanding aggregate principal amount of all Loans
exceeds the Commitments, make a mandatory prepayment in an amount at least equal to the
aggregate, outstanding principal amount of all Loans in excess of the Commitments as reduced
or terminated, and, if such mandatory prepayment was not sufficient to reduce the unpaid
principal balance of the Loans to an amount that does not exceed the Commitments as reduced
or terminated, such prepayments to be in an amount equal to the excess, if any, of the
aggregate, outstanding principal amount of all Loans over the Commitments as so reduced or
terminated; and

     (c) shall, immediately upon any acceleration of the Stated Maturity Date of any Loans
pursuant to Section 8.2 or Section 8.3, repay all Loans, unless, pursuant to
Section 8.3, only a portion of all Loans is so accelerated.

Each prepayment of any Loan made pursuant to this Section 3.1 shall be without premium or
penalty, except as may be required by Section 4.4. No voluntary prepayment of principal of
any Loans shall cause a reduction in the Commitments. All amounts paid pursuant to this
Section 3.1 shall be applied first as prepayments on the Loans.

     SECTION 3.2. Interest Provisions. Interest on the outstanding principal amount of
Loans shall accrue and be payable by the Borrower in accordance with this Section 3.2.

     SECTION 3.2.1. Rates. Pursuant to an appropriately delivered Borrowing Request or
Continuation/Conversion Notice, the Borrower may elect that Loans comprising a Borrowing accrue
interest at a rate per annum: (a) on that portion maintained from time to time as a Base Rate Loan,
equal to the Adjusted Base Rate; (b) on that portion maintained as a Eurodollar Loan, during each
Interest Period applicable thereto, equal to the Adjusted Eurodollar Rate for such Interest Period,
provided that no interest shall accrue on any portion of the then outstanding Loan (or portion
thereof) to the extent the Borrower has delivered cash collateral to the Collateral Agent securing
such Loan (or portion thereof).

     All Eurodollar Loans shall bear interest from and including the first day of the applicable
Interest Period to (but not including) the last day of such Interest Period at the interest rate
determined as applicable to such Eurodollar Loan.

     SECTION 3.2.2. Post-Default Rates. After the date (after giving effect to any grace
period) any principal amount of any Loan is due and payable (whether on the Stated Maturity Date,
upon acceleration or otherwise), or after any other monetary Obligation of the Borrower shall have
become due and payable, or after the occurrence of any other Event of Default the Borrower shall
pay, but only to the extent permitted by Governmental Rule, interest (after as

22

 

well as before judgment) at a rate per annum equal to the sum of (x) the Adjusted Base Rate
from time to time in effect for Base Rate Loans plus (y) 2%.

     SECTION 3.2.3. Payment Dates. Interest accrued on each Loan shall be payable, without
duplication by the Borrower: (a) on the Stated Maturity Date therefor; (b) on the date of any
payment or prepayment or cash collateralization in accordance with the proviso in Section
3.2.1, in whole or in part, of principal outstanding on such Loan; (c) with respect to Base
Rate Loans, in arrears on the last Business Day of each calendar month occurring after the
Effective Date; (d) with respect to Eurodollar Loans, in arrears on the last day of each applicable
Interest Period; (e) with respect to any Base Rate Loans converted into Eurodollar Loans on a day
when interest would not otherwise have been payable pursuant to clause (c), on the date of
such conversion; and (f) on that portion of any Loans, the Stated Maturity Date of which is
accelerated pursuant to Section 8.2 or Section 8.3, immediately upon such
acceleration. Interest accrued on Loans or other monetary Obligations arising under this Agreement
or any other Loan Document after the date such amount is due and payable (whether on the Stated
Maturity Date, upon acceleration or otherwise) or after the occurrence shall be payable by the
Borrower upon demand.

ARTICLE IV

CERTAIN EURODOLLAR RATE AND OTHER PROVISIONS

     SECTION 4.1. Fixed Rate Lending Unlawful. If any Lender shall determine (which
determination shall, upon notice thereof to the Borrower and the Lenders, be conclusive and binding
on the Borrower) that the introduction of or any change in or in the interpretation of any law
makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful,
for such Lender to make, continue or maintain any Loan as, or to convert any Loan into, a
Eurodollar Loan of a certain type, the obligations of such Lenders to make, continue, maintain or
convert any such Loans shall, upon such determination, promptly be suspended until such Lender
shall notify the Administrative Agent that the circumstances causing such suspension no longer
exist, and all such Lenders Eurodollar Loans shall automatically convert into Base Rate Loans at
the end of the then-current Interest Periods with respect thereto or sooner, if required by such
law or assertion.

     SECTION 4.2. Deposits Unavailable. If the Administrative Agent shall have determined
that (a) Dollar deposits in the relevant amount and for the relevant Interest Period are not
available to the Administrative Agent in the Administrative Agent’s relevant market; or (b) by
reason of circumstances affecting the interbank dollar market generally adequate means do not exist
for ascertaining the interest rate applicable hereunder to Eurodollar Loans of such type, then,
upon notice from the Administrative Agent to the Borrower and the Lenders, the obligations of all
Lenders under Section 2.3 and Section 2.4 to make or continue any Loans as, or to
convert any Loans into, Eurodollar Loans of such type shall promptly be suspended until the
Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such
suspension no longer exist; and (c) all Eurodollar Loans shall automatically convert into Base Rate
Loans at the end of the then current Interest Periods with respect thereto.

23

 

     SECTION 4.3. Increased Eurodollar Loan Costs, etc. The Borrower agrees to reimburse
each Lender for any increase in the cost to such Lender of, or any reduction in the amount of any
sum receivable by such Lender with respect to, making, continuing or maintaining (or of its
obligation to make, continue or maintain) any Loans as, or of converting (or of its obligation to
convert) any Loans into, Eurodollar Loans. Such Lender shall promptly notify the Administrative
Agent and the Borrower in writing of the occurrence of any such event, such notice to state, in
reasonable detail, the reasons therefor and the additional amount required fully to compensate such
Lender for such increased cost or reduced amount. Such additional amounts shall be payable by the
Borrower directly to such Lender within five (5) days of its receipt of such notice, and such
notice shall, in the absence of manifest error, be conclusive and binding on the Borrower. The
Borrower will not be responsible for paying any amounts pursuant to this Section 4.3
accruing more than one hundred eighty (180) days prior to the receipt by the Borrower of the notice
referred to in the preceding sentence.

     SECTION 4.4. Funding Losses. In the event any Lender shall incur any loss or expense
(including any loss or expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender to make, continue or maintain any portion of the principal
amount of any Loan as, or to convert any portion of the principal amount of any Loan into, a
Eurodollar Loan) as a result of (a) any conversion or repayment or prepayment of the principal
amount of any Eurodollar Loans on a date other than the scheduled last day of the Interest Period
applicable thereto, whether pursuant to Section 3.1 or otherwise; (b) any Loans not being
made as Eurodollar Loans in accordance with the Borrowing Request therefor; or (c) any Loans not
being continued as, or converted into, Eurodollar Loans in accordance with the
Continuation/Conversion Notice therefor, then, upon the written notice of such Lender to the
Borrower (with a copy to the Administrative Agent), the Borrower shall, within five (5) days of its
receipt thereof, pay directly to such Lender such amount as will (in the reasonable determination
of such Lender) reimburse such Lender for such loss or expense. Such written notice (which shall
include calculations in reasonable detail) shall, in the absence of manifest error, be conclusive
and binding on the Borrower.

     SECTION 4.5. Increased Capital Costs. If any change in, or the introduction,
adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of law) of any court,
central bank, regulator or other governmental authority affects or would affect the amount of
capital required or expected to be maintained by any Lender or any Person controlling such Lender,
and such Lender determines (in its sole and absolute discretion) that the rate of return on its or
such controlling Person’s capital as a consequence of its Commitment, or the Loans made by such
Lender is reduced to a level below that which such Lender or such controlling Person could have
achieved but for the occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender to the Borrower, the Borrower shall immediately pay directly to such
Lender additional amounts sufficient to compensate such Lender or such controlling Person for such
reduction in rate of return. A statement of such Lender as to any such additional amount or
amounts (including calculations thereof in reasonable detail) shall, in the absence of manifest
error, be conclusive and binding on the Borrower. In determining such amount, such Lender may use
any method of averaging and attribution that it (in its sole and absolute discretion) shall deem
applicable.

24

 

     SECTION 4.6. Taxes. All payments by the Borrower of principal of, and interest on,
the Loans and all other amounts payable hereunder and under any other Loan Document shall be made
free and clear of and without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or
measured by any Lender’s net income or receipts (such non-excluded items being called “Taxes”). In
the event that any withholding or deduction from any payment to be made by the Borrower hereunder
is required with respect to any Taxes pursuant to any applicable Governmental Rule, then the
Borrower will (a) pay directly to the relevant authority the full amount required to be so withheld
or deducted; (b) promptly forward to the Administrative Agent an official receipt or other
documentation satisfactory to the Administrative Agent evidencing such payment to such authority;
and (c) pay to the Administrative Agent for the account of the Administrative Agent or such Lender
such additional amount or amounts as is necessary to ensure that the net amount actually received
by the Administrative Agent or such Lender will equal the full amount the Administrative Agent or
such Lender would have received had no such withholding or deduction been required. Moreover, if
any Taxes are directly asserted against the Administrative Agent or any Lender with respect to any
payment received by the Administrative Agent or such Lender hereunder, the Administrative Agent or
such Lender may pay such Taxes and the Borrower will promptly pay such additional amounts
(including any penalties, interest or expenses) as is necessary in order that the net amount
received by such Person after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount such Person would have received had such Taxes not been asserted.

     If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails
to remit to the Administrative Agent, for the account of the Administrative Agent, or any Lender,
the required receipts or other required documentary evidence, the Borrower shall indemnify the
Administrative Agent, or such Lender for any incremental Taxes, interest or penalties that may
become payable by the Administrative Agent or such Lender as a result of any such failure. For
purposes of this Section 4.6, a distribution hereunder by the Administrative Agent or any
Lender to or for the account of the Administrative Agent or any Lender shall be deemed a payment by
the Borrower.

     Each Lender which is organized under the laws of a jurisdiction outside the United States
shall, (i) on the day of the initial borrowing from each such Lender hereunder and (ii) from time
to time thereafter if requested by the Borrower or the Administrative Agent, provide the
Administrative Agent and the Borrower with the forms prescribed by the Internal Revenue Service of
the United States certifying as to such Lender’s status for purposes of determining exemption from
United States withholding taxes with respect to all payments to be made to such Lender hereunder
and under the other Loan Documents or other documents satisfactory to such Lender, the Borrower and
the Administrative Agent and indicating that all payments to be made to such Lender hereunder and
under the other Loan Documents are not subject to United States withholding tax. Unless the
Borrower and the Administrative Agent shall have received such forms or such documents indicating
that payments to such Lender hereunder and under the other Loan Documents are not subject to United
States withholding tax, the Borrower and the Administrative Agent shall be entitled to withhold
United States withholding taxes from such payments at the applicable statutory rate.

25

 

     SECTION 4.7. Payments, Computations, etc. Unless otherwise expressly provided, all
payments by the Borrower to the Lenders pursuant to this Agreement, the Notes or any other Loan
Document shall be made by the Borrower to the Administrative Agent for the pro rata
account of the Lenders entitled to receive such payment, provided that during the continuance of
any Event of Default all such payments shall be made by the Borrower to the AREP Agent. All such
payments required to be made to the Agents shall be made, without set off, deduction or
counterclaim, not later than 11:00 a.m., New York time, on the date due, in same day or immediately
available funds, to such account as the applicable Agent shall specify from time to time by notice
to the Borrower. Funds received after that time shall be deemed to have been received on the next
succeeding Business Day. The Administrative Agent shall promptly remit in same day funds to each
Lender its share, if any, of such payments received by the Administrative Agent for the account of
such Lender. All interest and fees shall be computed on the basis of the actual number of days
(including the first day but excluding the last day) occurring during the period for which such
interest or fee is payable over a year comprised of 360 days (or, in the case of interest on a Base
Rate Loan, 365 days or, if appropriate, 366 days). Whenever any payment to be made shall otherwise
be due on a day which is not a Business Day, such payment shall (except as otherwise required by
clause (c) of the definition of the term “Interest Period” with respect to Eurodollar
Loans) be made on the next succeeding Business Day and such extension of time shall be included in
computing interest and fees, if any, in connection with such payment.

     SECTION 4.8. Sharing of Payments. (a) If any Lender shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of set off or otherwise) on account of any
Loan (other than pursuant to the terms of Sections 4.3, 4.4, 4.5 and
4.6) in excess of its pro rata share of payments then or therewith obtained
by all Lenders, such Lender shall purchase from the other Lenders such participations in Loans made
by them as shall be necessary to cause such purchasing Lender to share the excess payment or other
recovery ratably with each of them; provided, however, that if all or any portion of the excess
payment or other recovery is thereafter recovered from such purchasing Lender, the purchase shall
be rescinded and each Lender which has sold a participation to the purchasing Lender shall repay to
the purchasing Lender the purchase price to the ratable extent of such recovery together with an
amount equal to such selling Lender’s ratable share (according to the proportion of (a) the amount
of such selling Lender’s required repayment to the purchasing Lender to (b) the total
amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by
the purchasing Lender with respect to the total amount so recovered. The Borrower agrees that any
Lender so purchasing a participation from another Lender pursuant to this Section 4.8 may,
to the fullest extent permitted by Governmental Rule, exercise all its rights of payment (including
pursuant to Section 4.9) with respect to such participation as fully as if such Lender were
the direct creditor of the Borrower in the amount of such participation. If under any applicable
bankruptcy, insolvency or other similar Governmental Rule, any Lender receives a secured claim in
lieu of a set off to which this Section 4.8 applies, such Lender shall, to the extent
practicable, exercise its rights with respect to such secured claim in a manner consistent with the
rights of the Lenders entitled under this Section 4.8 to share in the benefits of any
recovery on such secured claim.

     SECTION 4.9. Set off. Each Lender shall, upon the occurrence of any Default described
in clauses (a) through (d) of Section 8.1.8 with respect to the Borrower or
any Subsidiary or any other Obligor or, with the consent of the Agents, upon the occurrence of any

26

 

other Event of Default, have the right to appropriate and apply to the payment of the
Obligations owing to it (whether or not then due) any and all balances, credits, deposits, accounts
or moneys of the Borrower then or thereafter maintained with such Lender; provided, however, that
any such appropriation and application shall be subject to the provisions of Section 4.8.
Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set
off and application made by such Lender; provided, however, that the failure to give such notice
shall not affect the validity of such set off and application. The rights of each Lender under
this Section 4.9 are in addition to other rights and remedies (including other rights of
set off under applicable Governmental Rule or otherwise) which such Lender may have.

     SECTION 4.10. Use of Proceeds. The Borrower will, and will cause each Subsidiary to,
use the proceeds of the Loans for the Borrower’s and its Subsidiaries’ general limited liability
company, partnership or corporate purposes, including, without limitation, working capital. No
part of the proceeds of any Loan will be used, whether directly or indirectly, to acquire any
equity security of a class that is registered pursuant to Section 12 of the Exchange Act or any
Margin Stock, in violation of Regulation U.

     SECTION 4.11. Maximum Interest. It is the intention of the parties hereto to conform
strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the
obligations of the Borrower to each Lender under this Agreement shall be subject to the limitation
that payments of interest shall not be required to the extent that receipt thereof would be
contrary to provisions of law applicable to such Lender limiting rates of interest which may be
charged or collected by such Lender. Accordingly, if the transactions contemplated hereby would be
usurious under applicable law (including the Federal and state laws of the United States of
America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to a
Lender then, in that event, notwithstanding anything to the contrary in this Agreement, it is
agreed as follows:

     (a) the provisions of this Section 4.11 shall govern and control;

     (b) the aggregate of all consideration which constitutes interest under applicable law
that is contracted for, charged or received under this Agreement, or under any of the other
aforesaid agreements or otherwise in connection with this Agreement by such Lender shall
under no circumstances exceed the maximum amount of interest allowed by applicable law (such
maximum lawful interest rate, if any, with respect to such Lender herein called the “Highest
Lawful Rate”), and any excess shall be credited to the Borrower by such Lender (or, if such
consideration shall have been paid in full, such excess promptly refunded to the Borrower);

     (c) all sums paid, or agreed to be paid, to such Lender for the use, forbearance and
detention of the indebtedness of the Borrower to such Lender hereunder shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread throughout the
full term of such indebtedness until payment in full so that the actual rate of interest is
uniform throughout the full term thereof; and

     (d) if at any time the interest provided pursuant to Section 3.2 together with
any other fees payable pursuant to this Agreement and deemed interest under applicable

27

 

law, exceeds that amount which would have accrued at the Highest Lawful Rate, the
amount of interest and any such fees to accrue to such Lender pursuant to this Agreement
shall be limited, notwithstanding anything to the contrary in this Agreement to that amount
which would have accrued at the Highest Lawful Rate, but any subsequent reductions, as
applicable, shall not reduce the interest to accrue to such Lender pursuant to this
Agreement below the Highest Lawful Rate until the total amount of interest accrued pursuant
to this Agreement and such fees deemed to be interest equals the amount of interest which
would have accrued to such Lender if a varying rate per annum equal to the interest provided
pursuant to Section 3.2 had at all times been in effect, plus the amount of
fees which would have been received but for the effect of this Section 4.11.

the execution, delivery and performance by each Obligor of the Loan Documents to which it is a
party, have been duly authorized by all necessary action on its part; and the Loan Documents
constitute the legal, valid and binding obligations of each Obligor thereto, enforceable in
accordance with their terms, except to the extent that enforcement may be subject to any applicable
bankruptcy, insolvency or similar laws generally affecting the enforcement of creditors’ rights.

     SECTION 6.3. Non-Contravention. Neither the execution and delivery of the Loan
Documents, nor compliance with the terms and provisions hereof will conflict with or result in a
breach of, or require any consent which has not been obtained as of the Effective Date under, the
respective Organic Documents of any Obligor, or any Governmental Rule or any material agreement or
instrument to which any Obligor is a party or by which it is bound or to which it or its Properties
are subject, or constitute a default under any such agreement or instrument, or result in the

the terms of any such agreement or instrument other than the Liens created by the Loan Documents.

     SECTION 6.4. Government Approval, Regulation, etc. Except for filings necessary to

     (a) there has been no change or event which could reasonably be expected to have a
Material Adverse Effect, nor

33

 

     (b) neither the business nor the Property of the Borrower, any Subsidiary or any other
Obligor has been materially and adversely affected as a result of any fire, explosion,
earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo,

and its Subsidiaries are valid and subsisting, in full force and effect and there exists no
default or event or circumstance which with the giving of notice or the passage of time or

inquiries to the Borrower or any of its Affiliates regarding potential liability under any
Environmental Law;

     (c) Except as could not reasonably be expected to have a Material Adverse Effect, there

     (i) Except as could not reasonably be expected to have a Material Adverse Effect, to
the knowledge of the Borrower, no conditions exist at, on or under any Property now or
previously owned or leased by the Borrower which, with the passage of time, or the giving of
notice or both, would give rise to liability under any Environmental Law.

used for a purpose that violates, or would be inconsistent with, Regulation U.

     SECTION 6.15. Accuracy of Information. All factual information heretofore or
contemporaneously furnished by or on behalf of the Borrower or any other Obligor in writing to the
Collateral Agent, the Collateral Agent or any Lender for purposes of or in connection with this
Agreement, any Loan Document or any transaction contemplated hereby or thereby is, and all other
such factual information hereafter furnished by or on behalf of any Obligor to the Collateral
Agent, the Collateral Agent or any Lender will be, true and accurate in every material respect on
the date as of which such information is dated or certified and as of the date of execution and
delivery of this Agreement by to the Collateral Agent, the Collateral Agent or such

36

 

Lender, and such information is not, or shall not be, as the case may be, incomplete by
omitting to state any material fact necessary to make such information not misleading. There is no
fact existing with respect to the Borrower or any Subsidiary that could reasonably be expected to
have a Material Adverse Effect and which has not been set forth in this Agreement or the other

any Subsidiary prior to, or on, the Closing Date in connection with the transactions contemplated
hereby.

     SECTION 6.16. Defaults. Neither the Borrower nor any Subsidiary is in default, nor
has any event or circumstance occurred which, but for the expiration of any applicable grace period
or the giving of notice, or both, would constitute a default, under any material agreement or
instrument to which the Borrower or any Subsidiary is a party or by which the Borrower or any
Subsidiary is bound in any material respect. No Default hereunder has occurred and is continuing.

     SECTION 6.17. Compliance with Law. Neither the Borrower nor any Subsidiary has
violated any Governmental Rule or failed to obtain any Governmental Approval necessary for the
ownership of any of its Properties or the conduct of its business which could reasonably be
expected to have a Material Adverse Effect. The Oil and Gas Properties (and properties unitized
therewith) have been maintained, operated and developed in a good and workmanlike manner and in
conformity with all applicable Governmental Rules of all Governmental Authorities having
jurisdiction and in conformity with the provisions of all leases, subleases or other contracts
comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of
the Oil and Gas Properties, except to the extent the same could not reasonably be expected to have
a Material Adverse Effect.

     SECTION 6.18. Direct Benefit. The Borrowings hereunder are or will be, as applicable,
for the direct benefit of the Borrower. The Borrower and each of the Guarantors are engaged as an
integrated group in the business of oil and gas exploration and related fields, and any benefits to

with the purposes set forth in Section 4.10.

are located (or adjacent in the case of properties located on the Outer Continental Shelf), or by
possession, and, except for Liens permitted by Section 7.2.3, all such Liens shall be first
priority Liens, subject only to Permitted Liens.

perfecting first and prior liens or security interests in any real or personal Property
which is at such time Collateral or that was intended to be Collateral pursuant to any Loan
Document previously executed and not then released by the Collateral Agent; or Equity

opinions (in addition to those

40

 

required to be delivered under Article V) from legal counsel acceptable to the

confirming or protecting any Liens or other rights in Collateral.

     (c) The Borrower hereby authorizes the Collateral Agent to file one or more financing
or continuation statements, and amendments thereto, relative to all or any part of the
Collateral without the signature of the Borrower or any other Obligor where permitted by

provide to the Collateral Agent, from time to time upon reasonable request of the Collateral
Agent, information which is in the possession of the Borrower or its Subsidiaries or
otherwise reasonably obtainable by any of them, reasonably satisfactory to the Collateral
Agent as to the perfection and priority of the Liens created or intended to be created by

otherwise released pursuant to the terms of this Agreement.

Subsidiary is formed or acquired and (ii) pledge, or cause any Subsidiary to pledge, all
Equity Interests in such newly determined Subsidiary pursuant to a Pledge Agreement.

collaterally assigned or pledged to Collateral Agent.

THE AGENTS

     SECTION 9.1. Actions. Each of the Lenders hereby irrevocably appoints AREP O&G as the
Administrative Agent under this Agreement, and each of the Lenders hereby irrevocably appoints
Citicorp USA, Inc. as the Collateral Agent under and for purposes of this Agreement, the Notes and
each other Loan Document. Each Lender authorizes each such Agent to act as contemplated under this
Agreement, the Notes and each other Loan Document and to exercise such powers hereunder and
thereunder as are specifically delegated to or required of such Agents by the terms hereof and
thereof, together with such powers as may be reasonably incidental thereto. Each Lender hereby
indemnifies (which indemnity shall survive any termination of this Agreement) the Administrative
Agent and the Collateral Agent pro rata according to such Lender’s percentage of
all of the outstanding Obligations owing to all Lenders, whether or not related to any
singular, joint or concurrent negligence of the Administrative Agent or the Collateral
Agent, from and against any and all liabilities, obligations, losses, damages, claims,
costs or expenses of any kind or nature whatsoever which may at any time be imposed on, incurred
by, or asserted against, the Administrative Agent or the Collateral Agent in any way relating to or
arising out of this Agreement, the Notes and any other Loan Document, including reasonable
attorneys’ fees, and as to which the Administrative Agent or the Collateral Agent, as the case may
be, is not reimbursed by the Borrower; provided, however, that no Lender shall be liable for the
payment of any portion of such liabilities, obligations, losses, damages, claims, costs or expenses
which are determined by a court of competent jurisdiction in a final proceeding to have resulted
solely from the Collateral Agent’s or the Collateral Agent’s gross negligence or willful
misconduct. Neither the Administrative Agent nor the Collateral Agent shall be required to take
any action hereunder, under the Notes or under any other Loan Document, or to prosecute or defend
any suit with respect to this Agreement, the Notes or any other Loan Document, unless it is
indemnified hereunder to its satisfaction. If any indemnity in favor of the Administrative Agent
or the Collateral Agent shall be or become inadequate, in the Administrative Agent’s or the
Collateral Agent’s determination, as the case may be, the Administrative Agent or the Collateral
Agent may call for additional indemnification from the Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given. Notwithstanding any provision to the
contrary contained elsewhere in this Agreement or in any other Loan Document, neither the
Administrative Agent nor the Collateral Agent shall have any duties or responsibilities, except as
expressly set forth herein, nor shall the Administrative Agent or the Collateral Agent have or be
deemed to have any fiduciary relationship with any Lender or Hedging Counterparty, as applicable,
and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be
read into this Agreement or any other Loan Document or otherwise exist against the Administrative
Agent or the Collateral Agent. Without limitation of the foregoing, each of Borrower and Lenders
acknowledges and agrees that the Collateral Agent

53

 

has no duty or obligation to them that in any way restricts the Collateral Agent from
exercising its rights and remedies, and carrying out any duties that it may have, in its various
capacities as Hedging Counterparty, AREP Agent, or AREP Lender.

     SECTION 9.2. Funding Reliance, etc. Unless the Administrative Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 p.m., New York time, on the day
prior to a Borrowing that such Lender will not make available the amount which would constitute its
Percentage of such Borrowing on the date specified therefor, the Administrative Agent may assume
that such Lender has made such amount available to the Administrative Agent and, in reliance upon
such assumption, make available to the Borrower a corresponding amount. If and to the extent that
such Lender shall not have made such amount available to the Administrative Agent, such Lender and
the Borrower severally agree to repay the Administrative Agent immediately on demand such
corresponding amount together with interest thereon, for each day from the date the Administrative
Agent made such amount available to the Borrower to the date such amount is repaid to the
Administrative Agent, at the interest rate applicable at the time to Loans comprising such
Borrowing.

     SECTION 9.3. Exculpation. Neither the Administrative Agent nor the Collateral Agent
(in their capacities as such), nor any of their respective directors, officers, employees or
agents, shall be liable to any Lender for any action taken or omitted to be taken by it under this
Agreement or any other Loan Document, or in connection herewith or therewith, except for its own
willful misconduct or gross negligence, nor responsible for any recitals or warranties herein or
therein, nor for the effectiveness, enforceability, validity or due execution of this Agreement or
any other Loan Document, nor for the creation, perfection or priority of any Liens purported to be
created by any of the Loan Documents, or the validity, genuineness, enforceability, existence,
value or sufficiency of any collateral security, nor to make any inquiry respecting the performance
by the Borrower of its obligations hereunder or under any other Loan Document. Any such inquiry
that may be made by the Administrative Agent or the Collateral Agent shall not obligate it to make
any further inquiry or to take any action. Each of the Administrative Agent and the Collateral
Agent shall be entitled to rely upon advice of counsel concerning legal matters and upon any
notice, consent, certificate, statement or writing which the Administrative Agent or the Collateral
Agent believes to be genuine and to have been presented by a proper Person.*

     SECTION 9.4. Successors.

     (a) Subject to the appointment of a successor as provided below, the Administrative
Agent or the Collateral Agent may resign as such at any time upon at least thirty (30) days’
prior notice to the Borrower, all Lenders and all Hedging Counterparties. If the
Administrative Agent at any time shall resign, the Lenders may appoint another Lender as the
successor Administrative Agent, which shall thereupon become the Administrative Agent
hereunder. If the Collateral Agent shall at any time resign, the resigning Collateral Agent
may appoint a Hedging Counterparty as the successor

 

			
	1	 	Since the Hedging Counterparties will not
be parties to this Agreement, they need to give this exculpation to the
Collateral Agent in the Mortgages.

54

 

Collateral Agent, which shall thereupon become the Collateral Agent hereunder. If a
successor Administrative Agent or Collateral Agent shall have been so appointed, but shall
not have accepted such appointment, within thirty (30) days after notice of resignation of
the retiring Administrative Agent or Collateral Agent, as the case may be, then the retiring
Administrative Agent or Collateral Agent, as the case may be, may appoint a successor
Administrative Agent or Collateral Agent, respectively, which shall be one of the Hedging
Counterparties or a commercial banking institution organized under the laws of the U.S. (or
any State thereof) or a U.S. branch or agency of a commercial banking institution, and
having a combined capital and surplus of at least $100,000,000. Upon the acceptance of any
appointment as Administrative Agent or Collateral Agent hereunder by a successor
Administrative Agent or Collateral Agent, respectively, such successor Administrative Agent
or Collateral Agent shall be entitled to receive from the retiring Administrative Agent or
Collateral Agent such documents of transfer and assignment as such successor Administrative
Agent or Collateral Agent may reasonably request, and shall thereupon succeed to and become
vested with all rights, powers, privileges and duties of the retiring Administrative Agent
or Collateral Agent, and the retiring Administrative Agent or Collateral Agent shall be
discharged from its duties and obligations under this Agreement. After any retiring
Administrative Agent’s or Collateral Agent’s resignation hereunder as the Administrative
Agent or Collateral Agent, respectively, the provisions of this Article IX shall
inure to its benefit as to any actions taken or omitted to be taken by it while it was the
Administrative Agent or Collateral Agent under this Agreement; and Section 10.3 and
Section 10.4 shall continue to inure to its benefit.

     (b) Each of the Borrower, the Lenders, the Administrative Agent, and the Collateral
Agent:

     (i) acknowledges and agrees that AREP O&G has pledged and granted a security
interest in all of its rights and powers under the Loan Documents, whether as Lender
or as Administrative Agent, to the AREP Agent,

     (ii) consents to and approves such pledge and security agreement,

     (iii) agrees that it will accept the AREP Agent as the Person entitled to
exercise the rights and powers of AREP O&G under the Loan Documents at any time when
the AREP Agent has declared that an “Event of Default” exists under the AREP O&G
Facility, and agrees further that the AREP Agent may possess and exercise such
rights and powers without assuming or otherwise becoming liable for any liabilities
or duties of AREP O&G in any of its capacities under the Loan Documents, and

     (iv) agrees that the AREP Agent is an express third party beneficiary of the
Loan Documents.

     SECTION 9.5. Extensions of Credit by the Agents. Each of the Agents shall have the
same rights and powers with respect to (x) the Loans made by it or any of its Affiliates, (y)

55

 

the Notes held by it or any of its Affiliates, and (z) the rights and powers held by it as
lender to or pledgee of AREP O&G, as any other Lender or Hedging Counterparty, as applicable, and
may exercise the same as if it were not an Agent. Each of the Agents and their respective
Affiliates may accept deposits from, lend money to, and generally engage in any kind of business
with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not an Agent
hereunder, as the case may be.

     SECTION 9.6. Credit Decisions. Each Lender acknowledges that it has, independently of
the Agents and each other Lender and Hedging Counterparty, and based on such Person’s review of the
financial information and reserve based information of the Borrower and its Subsidiaries, this
Agreement, the other Loan Documents (the terms and provisions of which being satisfactory to such
Lender) and such other documents, information and investigations as such Person has deemed
appropriate, made its own credit decision to extend its Commitment. Each Lender also acknowledges
that it will, independently of the Agents and each other Lender and Hedging Counterparty, and based
on such other documents, information and investigations as it shall deem appropriate at any time,
continue to make its own credit decisions as to exercising or not exercising from time to time any
rights and privileges available to it under this Agreement or any other Loan Document.

     SECTION 9.7. Copies, etc. The Administrative Agent shall give prompt notice to the
Collateral Agent, each Lender and Hedging Counterparty of each notice or request required or
permitted to be given to the Administrative Agent by the Borrower pursuant to the terms of this
Agreement (unless concurrently delivered to the Lenders by the Borrower). The Administrative Agent
will distribute to the Collateral Agent, each Lender and each Hedging Counterparty each document or
instrument received for its account and copies of all other communications received by the
Administrative Agent from the Borrower for distribution to the Collateral Agent and the Lenders in
accordance with the terms of this Agreement.

ARTICLE X

MISCELLANEOUS PROVISIONS

     SECTION 10.1. Waivers, Amendments, etc. The provisions of this Agreement and of each
other Loan Document may from time to time be amended, modified or waived, if such amendment,
modification or waiver is in writing and consented to by the Borrower, the Lenders and the Agents.
No failure or delay on the part of any Agent, any Lender, any Hedging Counterparty or the holder of
any Note in exercising any power or right under this Agreement or any other Loan Document shall
operate as a waiver thereof, nor shall any single or partial exercise of any such power or right
preclude any other or further exercise thereof or the exercise of any other power or right. No
notice to or demand on the Borrower in any case shall entitle it to any notice or demand in similar
or other circumstances. No waiver or approval by any Agent, any Lender, any Hedging Counterparty or
the holder of any Note under this Agreement or any other Loan Document shall, except as may be
otherwise stated in such waiver or approval, be applicable to subsequent transactions. No waiver
or approval hereunder shall require any similar or dissimilar waiver or approval thereafter to be
granted hereunder.

56

 

     SECTION 10.2. Notices. All notices and other communications provided to any party
hereto under this Agreement or any other Loan Document shall be in writing or by facsimile and

such party in a notice to the other parties. Any notice, if mailed and properly addressed with
postage prepaid or if properly addressed and sent by pre-paid courier service, shall be deemed
given when received; any notice, if transmitted by facsimile, shall be deemed given when
transmitted and a receipt, demonstrating successful transmission, is received by the Sender.
Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of
this Agreement or any other Loan Document shall be effective as delivery of an original executed
counterpart hereof.

     SECTION 10.3. Payment of Costs and Expenses. The Borrower agrees to pay on demand all
expenses of the Administrative Agent and the Collateral Agent in connection with

     (a) the negotiation, preparation, execution and delivery of this Agreement and of each
other Loan Document, including schedules and exhibits, and any amendments, waivers,
consents, supplements or other modifications to this Agreement or any other Loan Document as
may from time to time hereafter be required, whether or not the transactions contemplated
hereby are consummated;

     (b) the filing, recording, refiling or rerecording of each of the Security Documents
and/or any Uniform Commercial Code financing statements relating thereto and all amendments,
supplements and modifications to any thereof and any and all other documents or instruments
of further assurance required to be filed or recorded or refiled or rerecorded by the terms
hereof or of the Security Documents; and

     (c) the preparation and review of the form of any document or instrument relevant to
this Agreement or any other Loan Document. Each Lender and Hedging Counterparty agrees to
reimburse the Administrative Agent, the Collateral Agent and each Lender and Hedging
Counterparty on demand for such Lender’s (or Hedging Counterparty, as applicable) pro rata
share (based upon its respective percentage of all of the outstanding Obligations
represented by such Person’s outstanding Obligations) of any such costs or expenses not paid
by the Borrower. The Borrower further agrees to pay, and to save the Administrative Agent,
the Collateral Agent, the Lenders and the Hedging Counterparties harmless from all liability
for, any stamp or other taxes which may be payable in connection with the execution or
delivery of this Agreement, the Borrowings hereunder, or the issuance of the Notes or any
other Loan Documents. The Borrower also agrees to reimburse the Administrative Agent, the
Collateral Agent, the Lenders and the Hedging Counterparties upon demand for all
out-of-pocket expenses (including reasonable attorneys’ fees and legal expenses) incurred by
the Administrative Agent, the Collateral Agent, such Lender or such Hedging Counterparty in
connection with (x) the negotiation of any restructuring or “work-out,” whether or not
consummated, of any Obligations and (y) the enforcement of any Obligations.

     SECTION 10.4. Indemnification. In consideration of the execution and delivery of this
Agreement by the Administrative Agent, the Collateral Agent, each Lender and each

57

 

Hedging Counterparty, and the extension of the Commitments, and the arrangement of the
facility represented by this Agreement, the Borrower hereby indemnifies, exonerates and holds the
Administrative Agent, the Collateral Agent, each Lender and each Hedging Counterparty and each of
their respective Affiliates, officers, directors, employees and agents (collectively, the
"Indemnified Parties”) free and harmless from and against any and all actions, causes of action,
suits, losses, costs, liabilities and damages, and expenses incurred in connection therewith
(irrespective of whether any such Indemnified Party is a party to the action for which
indemnification hereunder is sought), including reasonable attorneys’ fees and disbursements
(collectively, the “Indemnified Liabilities”), incurred by the Indemnified Parties or any of them
as a result of, or arising out of, or relating to

     (a) any transaction financed or to be financed in whole or in part, directly or
indirectly, with the proceeds of any Borrowing;

     (b) the entering into and performance of this Agreement and any other Loan Document by
any of the Indemnified Parties (including any action brought by or on behalf of the Borrower
as the result of any determination by the Lenders pursuant to Article V not to fund
any Borrowing);

     (c) any investigation, litigation or proceeding related to any environmental cleanup,
audit, compliance or other matter relating to the protection of the environment or the
Release by the Borrower or any of its Subsidiaries or any Obligor of any Hazardous Material;

or any of its Subsidiaries or by any other Obligor of any Hazardous Material (including any
losses, liabilities, damages, injuries, costs, expenses or claims asserted or arising under
any Environmental Law); or

     (e) any misrepresentation or inaccuracy or breach of Section 6.13 without
giving effect to any knowledge qualification therein contained, regardless of whether caused
by, or within the control of, the Borrower or such Obligor or such Subsidiary; in each case
except for any such Indemnified Liabilities arising for the account of a particular
Indemnified Party by reason of the relevant Indemnified Party’s gross negligence or willful
misconduct, as determined by a court of competent jurisdiction in a final non-appealable
judgment, or such Indemnified Party’s own unexcused breach of any provision of any Loan
Document (as determined by the final non-appealable judgment of a court of competent
jurisdiction), PROVIDED THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT THE INDEMNIFIED
PARTIES BE INDEMNIFIED IN THE CASE OF THEIR OWN NEGLIGENCE, REGARDLESS OF WHETHER SUCH
NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. If and
to the extent that the foregoing undertaking may be unenforceable for any reason, the
Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of
each of the Indemnified Liabilities which is permissible under applicable law.

58

 

     SECTION 10.5. Survival. The obligations of the Borrower under Sections 4.3,

other indemnification or exculpation provisions of any Loan Document, and the obligations of the
Lenders under Section 9.1, shall in each case survive any termination of this Agreement,
the payment in full of all Obligations and the termination of all Commitments. The representations
and warranties made by the Borrower and each other Obligor in this Agreement and in each other Loan
Document shall survive the execution and delivery of this Agreement and each such other Loan
Document.

     SECTION 10.6. Hedging Counterparties Are Third Party Beneficiaries. The benefit of
the Security Documents and of the provisions of this Agreement relating to the Collateral shall
also extend to and be available to the Hedging Counterparties with respect to any Hedging
Obligations of the Borrower or any of its Subsidiaries that are in effect, and the Hedging
Counterparties are express third party beneficiaries of the Loan Documents.

     SECTION 10.7. Severability. Any provision of this Agreement or any other Loan
Document which is prohibited or unenforceable in any jurisdiction shall, as to such provision and
such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions of this Agreement or such Loan Document or affecting the
validity or enforceability of such provision in any other jurisdiction.

     SECTION 10.8. Headings. The various headings of this Agreement and of each other Loan
Document are inserted for convenience only and shall not affect the meaning or interpretation of
this Agreement or such other Loan Document or any provisions hereof or thereof.

     SECTION 10.9. Execution in Counterparts, Effectiveness, etc. This Agreement may be
executed by the parties hereto in several counterparts, each of which shall be deemed to be an
original and all of which shall constitute together but one and the same agreement. This Agreement
shall become effective when counterparts hereof executed on behalf of the Borrower and each Lender
and Agent (or notice thereof satisfactory to the Administrative Agent) shall have been received by
the Administrative Agent.

     SECTION 10.10. Governing Law; Entire Agreement. THIS AGREEMENT, THE NOTES AND EACH
OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO THE PRINCIPLES

AND EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER JURSIDICATION ARE EXPRESSLY ELECTED IN ANOTHER
LOAN DOCUMENT. This Agreement, the Notes and the other Loan Documents constitute the entire
understanding among the parties hereto with respect to the subject matter hereof and supersede any
prior agreements, written or oral, with respect thereto.

     SECTION 10.11. Successors and Assigns. This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors and assigns; provided,
however, that:

59

 

     (a) none of the Borrower or any Lender may assign or transfer its rights or obligations
hereunder without the prior written consent of each other party hereto, provided, however,
that for purposes of this Section 10.11 if the survivor of a merger is obligated
with respect to all obligations of the Borrower hereunder and under all other Loan
Documents, a merger permitted pursuant to Section 7.2.8 hereof shall not be an
assignment or transfer of the Borrower’s rights or obligations hereunder; and

     (b) notwithstanding the preceding subsection (a), AREP O&G may pledge and collaterally
assign all of its rights under the Loan Documents (in whatever capacities) to AREP Agent
(including any successor AREP Agents), and upon enforcement of such pledge and collateral
assignment any purchaser or other successor to AREP O&G (whether at a foreclosure sale,
under a deed in lieu of foreclosure, or otherwise) may thereafter freely assign all of its
rights under the Loan Documents.

     SECTION 10.12. [Reserved]

     SECTION 10.13. Other Transactions. Nothing contained herein shall preclude the
Administrative Agent, the Collateral Agent or any other Lender from engaging in any transaction, in
addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or
any of its Affiliates in which the Borrower or such Affiliate is not restricted hereby from
engaging with any other Person.

     SECTION 10.14. Confidentiality. In the event that the Borrower provides to the
Administrative Agent or the Lenders confidential information belonging to the Borrower or any of
the other Obligors, then the Administrative Agent and the Lenders shall thereafter maintain such
information in confidence in accordance with the standards of care and diligence that each utilizes
in maintaining its own confidential information. This obligation of confidence shall not apply to
such portions of the information that (a) are in the public domain, (b) hereafter become part of
the public domain without the Administrative Agent or the Lenders breaching their obligation of
confidence hereunder, (c) are previously known by the Administrative Agent or the Lenders from some
source other than the Borrower, (d) are hereafter developed by the Administrative Agent or the
Lenders without using the Borrower’s information, (e) are hereafter obtained by or available to the
Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the
Borrower with respect to such information or through any other means other than through disclosure
by the Borrower, (f) are disclosed with the Borrower’s consent (it being acknowledged that the
Borrower consents to Lender’s provision of such information to the Collateral Agent, the AREP Agent
and the AREP Lenders), (g) must be disclosed either pursuant to any Governmental Rule or to Persons
regulating the activities of the Administrative Agent or the Lenders, or (h) as may be required by
law or regulation or order of any Governmental Authority in any judicial, arbitration or
governmental proceeding. Furthermore, the Administrative Agent or a Lender may disclose any such
information to any other Lender, any independent petroleum engineers or consultants, any
independent certified public or chartered accountants, any legal counsel employed by such Person in
connection with this Agreement or any other Loan Document, including without limitation, the
enforcement or exercise of all rights and remedies thereunder, or any assignee or participant
(including prospective assignees and participants) in the Loans; provided, however, that the
Administrative Agent or the Lenders shall receive a confidentiality agreement from the Person to
whom such

60

 

information is disclosed such that said Person shall have the same obligation to maintain the
confidentiality of such information as is imposed upon the Administrative Agent or the Lenders
hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence
shall cease one (1) year from the Effective Date, unless the Borrower requests in writing at least
thirty (30) days prior to the expiration of such three-year period, to maintain the confidentiality
of such information for an additional three-year period. The Borrower waives any and all other
rights it may have to confidentiality as against the Administrative Agent and the Lenders arising
by contract, agreement, statute or law except as expressly stated in this Section 10.14.

     SECTION 10.15. Non-Recourse to Officers and Directors. This Agreement and the
Obligations are fully recourse to Borrower and the other Obligors. Notwithstanding anything to the
contrary contained in this Agreement or in any other Loan Document, no recourse under or upon any
Obligation, representation, warranty or covenant shall be had against any of the officers,
directors, employees, agents or representatives of the Borrower or any other Obligor; provided,
however, that nothing in this Section 10.15 shall be deemed to constitute a waiver of any
Obligation evidenced or secured by, or contained in, this Agreement or any other Loan Document, or
affect in any way the validity or enforceability of this Agreement or any other Loan Document.

     SECTION 10.16. Forum Selection and Consent to Jurisdiction. ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT,
OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF
THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT, THE LENDERS OR THE BORROWER MAY BE BROUGHT AND
MAINTAINED IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY
COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE ADMINISTRATIVE AGENT’S OPTION, IN THE COURTS OF
ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND. EACH OF THE ADMINISTRATIVE
AGENT, THE COLLATERAL AGENT, THE LENDERS AND THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS
TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND OF THE UNITED STATES DISTRICT COURT
FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND
IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH LITIGATION.
EACH OF THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT, THE LENDERS AND THE BORROWER FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK. EACH OF THE ADMINISTRATIVE AGENT, THE COLLATERAL
AGENT, THE LENDERS AND THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER

61

 

MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO
ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE
EXTENT THAT THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT
OF FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE BORROWER
HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY WITH RESPECT TO ITS OBLIGATIONS UNDER THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS.

     SECTION 10.17. Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, (A) ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY
LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT
OR ANY OTHER THEORY, AND (B) ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LEGAL PROCEEDING
ANY “SPECIAL DAMAGES,” AS DEFINED BELOW. EACH PARTY HERETO (X) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER
PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (Y)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION. AS USED IN THIS SECTION, “SPECIAL DAMAGES” INCLUDES ALL SPECIAL, CONSEQUENTIAL,
EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR
FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO.

     SECTION 10.18. No Oral Agreements. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
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 AMONG THE PARTIES.

     This Borrowing Request is delivered to you pursuant to Section 2.3 of the Amended and Restated

the Lender) (collectively, the “Lenders”), AREP Oil & Gas LLC, as administrative agent (in such
capacity together with any successors thereto, the “Administrative Agent”) for the Lenders, and the
other agents and lenders party thereto. Unless otherwise defined herein or the context otherwise
requires, capitalized terms used herein have the meanings provided in the Credit Agreement.

     The Borrower hereby requests that a Loan be made in the aggregate principal amount of

POST-CLOSING COVENANTS

     The parties agree as follows with respect to the period following the Closing:

     10.1 General. If, during the three (3) year period following Closing, any further
action is necessary or desirable to carry out the purposes of this Agreement, each party will take
such further action (including the execution and delivery of further instruments and documents) as
any other party reasonably requests, all at the sole cost and expense of the requesting party
(unless the requesting party is entitled to indemnification therefor).

     10.2 Litigation Support. Except with respect to the matter discussed in Section 10.5,
if, during the three (3) year period following Closing and for so long as any party actively is
contesting or defending against any action commenced during such period, in connection with (a) any
transaction contemplated under this Agreement or (b) any fact, circumstance, condition, event,
failure to act, or transaction on or prior to the Closing involving Buyer or any Seller, except to
the extent adverse to its own interest, each other party will cooperate with such party and its
counsel in the contest or defense, make available its personnel, and provide such testimony and
access to its books and records as is reasonably necessary in connection with such contest or
defense, all at the sole cost and expense of the contesting or defending party, provided that the
contesting or defending party will not be charged for reasonable manpower hours of the other
party’s personnel who provide assistance (unless the contesting or defending party is entitled to
indemnification therefor).

     10.3 Transition. During the period of three (3) years following Closing for Assets
other than the Shares, the Royalty Conversion Right and the Rock Creek Royalty Royalty, and during
the period coincident with the term of the Royalty Conversion Right for the Shares, the Royalty
Conversion Right and the Rock Creek Royalty, neither Sellers nor any affiliate, officer

-17-

 

or director thereof will take any action that is intended to, or could reasonably be
anticipated to, adversely affect the Assets or the benefits therefrom accruing to Buyer; provided,
however, that in the event a Seller determines, in good faith, that failing to take such action
would be materially adverse to the interest of such Seller, Seller may take such action to the
extent necessary to preserve its interests following written notice of same to Buyer sufficiently
in advance to allow Buyer to attempt to rectify same. Sellers will refer all inquiries directly
relating to the Assets to Buyer from and after Closing. In connection with the foregoing, (a) in
the event Buyer converts the Shares to the Rock Creek Royalty, Sellers shall cooperate with Buyer
in delivering to Revett a certified copy of the recorded instrument evidencing Buyer’s right, title
and interest to the Rock Creek Royalty and shall direct that any payments or notices relating to
the Rock Creek Royalty be delivered by Revett only to Buyer or its designated representative; and
(b) as to the Mulatos Royalty, Sellers shall cooperate with and assist Buyer in recording such
royalty in the Public Registry of Mining or other appropriate office of the Mexican government.

     10.4 Trust Fund. Notwithstanding the conveyance of the Robinson Royalty hereunder,
subject to such action as might be necessary to protect or preserve their rights and interests in
the Trust Agreement, the Trust Fund, the Stipulation and the Ancillary Agreement, Sellers will
continue to comply, fully and in good faith, with their obligations under the Trust Agreement,
Stipulation and Ancillary Agreement.

     10.5 Mulatos Royalty. Sellers have disclosed to Buyer a notice of claim from Alamos
dated September 30, 2005, concerning the Virgencita Concession. If, in connection with the dispute
as to the Virgencita Concession, there is a final judgment by a trial court of competent
jurisdiction that MON does not have rights under the Virgencita Concession, but the validity of the
Mulatos Royalty and Buyer’s ownership thereof is not otherwise impaired, then Sellers shall not be
liable to Buyer for loss of royalty related to loss of the Virgencita Concession. However, if for
any reason related to claims by Alamos or MON against Sellers, it is determined by a trial court of
competent jurisdiction that the right to the Mulatos Royalty is rescinded, unenforceable, void or
otherwise nullified or if, as a result of such determination or as a result of a settlement reached
by Sellers in any such dispute, the Mulatos Royalty is otherwise adversely affected (which, for
purposes of this Agreement means that the court orders, or Sellers in such settlement agree to,
repayment of, or a reduction in future payments of, US$750,000 or more under such royalty), then,
within 90 days of the date of determination by the trial court or such settlement, Buyer may elect
to have Sellers refund to Buyer US$5,600,000 of the original Purchase Price, reduced by any
amounts paid to Buyer under such royalty that do not have to be refunded to Alamos or MON, in which
case Buyer shall simultaneously deliver to Sellers a reconveyance and release of any claim to the
Mulatos Royalty together with the amount, if any, by which such royalties paid to Buyer that do not
have to be returned to Alamos or MON exceed US$5,600,000. Notwithstanding the foregoing, if the
decision of the trial court is appealed, Buyer may defer its election and await the outcome of any
appeal of the trial court’s determination, not subject to further review, and if the appellate
court issues a final judgment that the Mulatos Royalty is rescinded, unenforceable, void or is
otherwise adversely affected, Buyer may elect to have the Purchase Price returned in exchange for
the Mulatos Royalty on the same basis as set forth in the preceding sentence. Such election must
be made within 30 days of the final decision by the appellate court not subject to further review.
If an election is timely made by Buyer in either of the circumstances described above, a closing of
the transaction described above will occur within 30 days of the date of Buyer’s election. In the
event of a disagreement between the parties as to

-18-

 

any ultimate amount to be refunded, the amount not in dispute shall be refunded within the
above stated period. Buyer may elect to intervene as a party in any judicial proceedings that it
reasonably determines may affect its rights or interests in the Mulatos Royalty, if such
intervention is possible under the rules of procedure applicable to the proceeding. If Buyer so
elects to intervene, it shall be solely responsible for all costs and expenses (including but not
limited to attorneys’ fees) incurred by it, and Sellers shall have no obligation to reimburse Buyer
for same. Buyer also shall have the right to request of and receive from Sellers an assignment of
any claims that any of the Sellers may have against third parties with respect to a claim by Alamos
relating to the Mulatos Royalty. Upon receipt of that claim from Sellers, Buyer shall be
responsible for defending any counterclaim brought by such third party and shall indemnify Sellers
from and against any costs, expenses or damages resulting from either its claim or the third
party’s counterclaim.

     10.6 Proration of Royalty Payments. If, during the three (3) year period following
Closing, either party receives a payment of the Mulatos Royalty or the Robinson Royalty that covers
a period both before and after Closing, the parties shall seek for a period of 60 days to obtain
specific information accompanying the payment as to when the payment accrued and prorate the
payment accordingly. If such specific information cannot be obtained, any such payment shall be
prorated by dividing the amount of the payment by the number of days in the period to which the
statement accompanying the payment pertains and then attributing to Sellers the per diem amount for
each day prior to Closing and to Buyer the per diem amount for the Closing Date and each day
thereafter.

     10.7 Access to Books and Records. During the one (1) year period following Closing
Sellers shall maintain and make available to Buyer for review and copying at Buyer’s expense and
subject to satisfaction of any limitations on disclosure under any relevant agreements, any all
books, records, manuals and other materials in the possession of Sellers and that can be located by
Sellers relating to the Assets, including, without limitation, (i) all production data and
financial and accounting records or reports provided to or produced by the Sellers regarding any
royalty described herein (including records of tonnage, product volume, analyses of products,
weight, moisture, assays of pay metal content, allowable deductions for further processing and
other records related to the computation of any such royalty), (ii) the results and supporting
materials of any audit regarding the payment of any royalty described herein, (iii) all reports
regarding or relating to the reclamation or remediation of any real property subject to any royalty
described herein; (iv) all correspondence between Sellers and the payors of the Mulatos Royalty and
Robinson Royalty concerning such royalties; (v) any and all annual or interim reports submitted to
Sellers by the royalty payors of the activities conducted upon or to be conducted upon the real
property subject to any royalty described herein; and (vi) any reports or analyses produced by or
for Sellers with respect to any inspections of the surface or subsurface portions of the real
property subject to any royalty described herein or the improvements or operations thereon;
provided that any such access will be made upon reasonable advance notice during normal business
hours in such a manner as to not unduly interfere with Sellers’ operations.

a third party, the indemnified party shall provide written notice (the “Claim Notice”) to the
indemnifying party of any such claim within five (5) days after becoming aware of such claim;
provided, however, that the indemnifying party shall have no obligation to indemnify the indemnitee
against Damages, if any, resulting directly from the failure to timely give a Claim Notice, but
that such failure will not be deemed a forfeiture of the rights granted by this Section 11.3. The
parties shall make available to each other all information that is in their possession and is
material to any such claim. The indemnifying party may defend at its expense any third-party claim
against the indemnified party, so long as the notice of the intent to control the defense is given
to the indemnified party within five (5) days after receipt of the Claim Notice by the indemnifying
party. The indemnified party shall cooperate with the indemnifying party in such defense, and may
employ counsel at its own expense.

     11.4 Virgencita Concession Indemnification. With respect to any action taken against
Buyer by Alamos, MON or any other party concerning the validity of the Mulatos Royalty as a result
of the dispute regarding the Virgencita Concession referenced in Section 10.5, Sellers shall have
the right, but not the obligation, to assume Buyer’s defense of such action and to prosecute or
settle same.

-20-

 

     (a) If Sellers assume Buyer’s defense of such action, Sellers’ indemnification liability shall
be limited to reimbursement of any cost or attorneys fees incurred by Buyer in defending such claim
during the period (not to exceed ten (10) days) prior to the assumption of the defense by Sellers
and to the return of the amount set out in Section 10.5 if an adverse decision is received from a
trial court or appellate court or if the Mulatos Royalty is otherwise adversely affected, as
provided in Section 10.5, as a result of a settlement reached by Sellers in any such dispute, and
the other requirements of Section 10.5 are met.

     (b) If Sellers elect not to assume defense of such action, Buyer may elect within twenty (20)
days of the date Sellers give Buyer notice of such decision (i) to return the Mulatos Royalty to
Sellers in exchange for US$5,600,000 of the original Purchase Price, reduced by any amounts paid to
Buyer under such royalty that do not have to be refunded to Alamos or MON (and provided that if
Buyer has been paid in excess of US$5,600,000 it shall refund to Seller the amount by which such
payments exceed US$5,600,000), in which case Sellers will assume responsibility for any damages
imposed on Buyer arising out of such action and Buyer shall have no further rights or obligations
with respect to the Mulatos Royalty or such action, or (ii) to retain the Mulatos Royalty and
defend the action, retain any royalties that have been paid, assume responsibility for any damages
that might result and release Seller from any liability with respect to the Mulatos Royalty.
Notwithstanding Buyer’s election to defend the action, upon the earlier of: (x) ninety (90) days
after an adverse decision by a trial court, or (y) two (2) years after the date of Buyer’s election
to defend the action, Buyer may further elect by written notice to Sellers to terminate its defense
of the action and return the Mulatos Royalty to Sellers in exchange for US$5,600,000 of the
original Purchase Price, reduced by any amounts paid to Buyer under such royalty that do not have
to be refunded to Alamos or MON (and provided that if Buyer has been paid in excess of
US$5,600,000, it shall refund to Seller the amount by which such payments exceed US$5,600,000). In
addition, in this case, Sellers shall assume responsibility for any damages imposed on Buyer
arising out of such action, and Buyer shall have no further rights or obligations with respect to
the Mulatos Royalty or such action, provided, however, that to the extent damages
(including attorneys’ fees and interest) have been or ultimately are awarded to Alamos or MON, and
such damages are greater than those claimed or that would have been imposed at the date of Buyer’s
election, the additional amount of damage shall be Buyer’s sole responsibility.

     (c) If Buyer makes the election to return the Mulatos Royalty to Sellers following Buyer’s
assumption of defense of such action, all legal costs and expenses incurred by Buyer in defending
the action and any settlement costs paid or agreed to by Buyer prior to its termination of its
defense pursuant to Section 11.4(b)(ii) (which settlement shall be entered into only following
consultation throughout the settlement process with Sellers and which shall be subject to Sellers’
prior written approval) shall be at Buyer’s sole cost and expense, and Sellers shall have no
obligation to reimburse Buyer for all or any portion of same. If Buyer does not elect to return
the Mulatos Royalty to Sellers, then all legal costs and expenses incurred by Buyer in defending
the action and any settlement costs paid or agreed to by Buyer shall be at Buyer’s sole cost and
expense, and Sellers shall have no obligation to reimburse Buyer for all or any portion of same,
provided further that Sellers shall have no right to consultation with Buyer regarding any
such settlement or to participate in any such settlement.

-21-

 

     11.5 Non-Third Party Claims. If the indemnified party asserts the existence of a
claim, other than a claim by a third party, it shall give written notice to the indemnifying party
specifying the nature and amount of the claim asserted. Within 30 days after such notice of a
claim has been received by the indemnifying party, the indemnifying party may give written notice
to the indemnified party of its intent to contest the assertion of the indemnified party; if no
such notice is received, the assertion by the indemnified party will be deemed accepted by the
indemnifying party. If the indemnifying party does contest the assertion of the claim, an
authorized representative of each party shall attempt in good faith to resolve the dispute for a
period of 30 days. If the dispute is not resolved as agreed in writing by the parties at the end
of such 30-day period, either party may pursue the rights and remedies available to it at law or in
equity.

Any party may change the address to which Notices are to be delivered by giving the other parties
notice in the manner herein set forth.

     12.7 Governing Law. This Agreement will be governed by and construed in accordance
with the laws of the State of Utah without giving effect to any choice or conflict of law provision
or rule that would cause the application of the laws of any jurisdiction other than the State of
Utah.

-23-

 

     12.8 Amendments and Waivers. No amendment or waiver of any provision of this
Agreement will be valid unless it is in writing and signed by each party. No such waiver by any
party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, will be deemed to extend to any prior or subsequent default, misrepresentation,
or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of
any prior or subsequent such occurrence.

     12.9 Severability. Any term or provision of this Agreement that is invalid or
unenforceable in any situation in any jurisdiction will not affect the validity or enforceability
of the remaining terms and provisions hereof or the validity or enforceability of the offending
term or provision in any other situation or in any other jurisdiction.

     12.10 Expenses. Each Seller, on the one hand, and Buyer, on the other hand, will bear
its own costs and expenses (including legal fees and expenses) incurred in connection with this
Agreement and the transactions contemplated hereby. Any transfer or sales taxes arising by virtue
of the sale of the Assets by Sellers to Buyer will be borne by Buyer.

     12.11 Construction. The parties have participated jointly in the negotiation and
drafting of this Agreement. In the event an ambiguity or question of intent or interpretation
arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or
burden of proof will arise favoring or disfavoring any party by virtue of the authorship of this
Agreement. Unless the context otherwise requires: (a) “or” is not exclusive; (b) words in the
singular include the plural, and words in the plural include the singular; (c) reference to a law,
statute, rule, regulation, organizational document and the like is deemed to be followed by “as in
effect on the date of this Agreement”; (d) “herein,” “hereof,” and other similar words refer to
this Agreement as a whole and not to any particular section, subsection, paragraph, clause, or
other subdivision; (e) “include,” “includes,” or “including” will be deemed to be followed, as
appropriate, by “, but not limited to,” (f) the masculine, feminine and neuter genders will each be
deemed to include the others; (g) “will,” “shall,” or “agrees” are mandatory, and “may” is
permissive; and (h) any reference to any federal, state, local, or foreign statute or law will be
deemed also to refer to all rules and regulations promulgated thereunder, unless the context
requires otherwise. The parties intend that each representation, warranty, and covenant contained
herein will have independent significance. If any party has breached any representation, warranty,
or covenant contained herein in any respect, the fact that there exists another representation,
warranty, or covenant relating to the same subject matter (regardless of the relative levels of
specificity) that the party has not breached will not detract from or mitigate the fact that the
party is in breach of the first representation, warranty, or covenant.

     12.12 Specific Performance. Each party acknowledges and agrees that the other parties
would be damaged irreparably if any provision of this Agreement is not performed in accordance with
its specific terms or otherwise is breached. Accordingly, the obligations of the parties hereunder
will be specifically enforceable.

     12.13 Survival. Except as specifically provided herein, the representations and
warranties contained in Articles II, III, IV, V and VI of this Agreement shall survive the Closing
and for a period of three (3) years thereafter.
