date a corresponding amount. If and to the extent that any Lender shall not have so made its Pro
Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower
severally agree to immediately repay to the Administrative Agent on demand such corresponding
amount, together with interest on such amount, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i)
in the case of the Borrower, the interest rate applicable on such day to Advances comprising such
Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for such day. If such Lender
shall repay to the Administrative Agent such corresponding amount and interest as provided above,
such corresponding amount so repaid shall constitute such Lender’s Advance as part of such
Borrowing for purposes of this Agreement even though not made on the same day as the other Advances
comprising such Borrowing.

     (f) Lender Obligations Several. The failure of any Lender to make the Advance to be
made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any,
to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure
of any other Lender to make the Advance to be made by such other Lender on the date of any
Borrowing.

     Section 2.03 Reduction of the Commitment.

     (a) The Commitments shall automatically and permanently be reduced to $0 upon the making of
the Advances on the Effective Date.

     Section 2.04 Prepayment of Advances.

     (a) Optional. At any time after the first anniversary of the Effective Date, the
Borrower may prepay the Advances, after giving by 11:00 A.M. (New York City time) at least three
Business Days’ irrevocable prior written notice to the Administrative Agent stating the proposed
date and aggregate principal amount of such prepayment. If any such notice is given, the Borrower
shall prepay the Advances in whole or ratably in part in an aggregate principal amount equal to the
amount specified in such notice, together with (i) the accrued interest to the date of such
prepayment on the principal amount prepaid and (ii) the amounts, if any, required to be paid
pursuant to Section 2.09 as a result of such prepayment being made on such date; provided, however,
that each partial prepayment shall be made in minimum amounts of $1,000,000 and in integral
multiples of $500,000 in excess thereof, and full prepayments of any Borrowing are permitted
without restriction of amounts.

     (b) Mandatory. (i) If a Change of Control shall occur and the Borrower has not
optionally prepaid in full the outstanding principal amount of the Advances concurrently with the
consummation of such Change of Control, at the Lenders’ option (which option may be exercised in
their sole discretion) the Borrower shall prepay the outstanding principal amount of the Advances,
in whole or in part as elected by the Lenders, together with (i) the accrued interest to the date
of such prepayment on the principal amount prepaid and (ii) the amounts, if any, required to be
paid pursuant to Section 2.09 as a result of such prepayment being made on such date. If the
Lenders require the Borrower to prepay the Advances as provided above, the Administrative Agent
shall so notify the Borrower in writing, which

-21-

 

notice shall specify the amount to be paid by the Borrower pursuant to this Section 2.04(b).
The Borrower shall pay all such amounts in full within two Business Days of receipt of such notice.
The foregoing will not be deemed to be a consent by Lenders to any Change of Control or a waiver
of any Default resulting therefrom.

     (ii) If on any date, the Borrower or any of its Subsidiaries shall receive Net Cash Proceeds
from an asset sale (other than a sale permitted pursuant to clause (i) and (ii) of Section 6.04 of
this Agreement) then, unless a Reinvestment Notice shall be delivered in respect thereof, such Net
Cash Proceeds shall be applied on such date toward the prepayment of the Advances, provided that,
notwithstanding the foregoing, on each Reinvestment Prepayment Date, an amount equal to the
Reinvestment Prepayment Amount shall be applied toward the prepayment of the Advances and provided,
further, that if such Net Cash Proceeds are applied toward the prepayment of the First Lien Debt
Obligations as required pursuant to Section 2.05(b) of the First Lien Credit Agreement, the
Borrower’s obligations to prepay the Advances shall be deemed satisfied on a dollar-for-dollar
basis to the extent of amounts applied to repay the advances under the First Lien Credit Agreement.

     (c) Prepayment Premium. Notwithstanding anything to contrary in clause (a) and (b)
above, prepayments of Advances shall be accompanied by the payment of interest on the principal
amount prepaid plus a prepayment premium on the principal amount prepaid equal to (i) the
Applicable Premium if the prepayment is made from the Effective Date through the first anniversary
thereof, (ii) 5% if the prepayment is made from the first anniversary of the Effective Date through
the second anniversary thereof, (iii) 3% if the prepayment is made from the second anniversary of
the Effective Date through the third anniversary thereof, (iv) 1% if the prepayment is made from
the third anniversary of the Effective Date through the fourth anniversary thereof and (v) 0%
thereafter.

     (d) Illegality. If any Lender shall notify the Administrative Agent and the Borrower
that the introduction of or any change in or in the interpretation of any law or regulation makes
it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful
for such Lender or its Eurodollar Lending Office to perform its obligations under this Agreement to
maintain any Eurodollar Rate Advances of such Lender then outstanding hereunder, (i) the Borrower
shall, no later than 11:00 A.M. (New York City time) (A) if not prohibited by law, on the last day
of the Interest Period for each outstanding Eurodollar Rate Advance made by such Lender or (B) if
required by such notice, on the second Business Day following its receipt of such notice, prepay
all of the Eurodollar Rate Advances made by such Lender then outstanding, together with accrued
interest on the principal amount prepaid to the date of such prepayment and amounts, if any,
required to be paid pursuant to Section 2.09 as a result of such prepayment being made on such
date, (ii) such Lender shall simultaneously make a Reference Rate Advance to the Borrower on such
date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid
to such Lender, and (iii) the right of the Borrower to select Eurodollar Rate Advances from such
Lender shall be suspended until such Lender shall notify the Administrative Agent that the
circumstances causing such suspension no longer exist.

     (e) No Additional Right; Ratable Prepayment. The Borrower shall have no right to
prepay any principal amount of any Advance except as provided in this Section 2.04, and all notices
given pursuant to this Section 2.04 shall be irrevocable and binding upon the Borrower. Each
payment of any Advance pursuant to this Section 2.04 shall be made in a manner such that all
Advances comprising part of the same Borrowing are paid in whole or ratably in part.

     Section 2.05 Repayment of Advances. The Borrower shall repay to the Administrative
Agent for the ratable benefit of the Lenders the outstanding principal amount of each Advance,
together with any accrued interest thereon, on the Maturity Date or such earlier date pursuant to
Section 7.02 or Section 7.03.

-22-

 

     Section 2.06 Interest. The Borrower shall pay interest on the unpaid principal amount
of each Advance made by each Lender from the date of such Advance until such principal amount shall
be paid in full, at the following rates per annum:

     (a) Reference Rate Advances. If such Advance is a Reference Rate Advance, a rate per
annum equal at all times to the Adjusted Reference Rate in effect from time to time plus the
Applicable Margin in effect from time to time, payable quarterly in arrears on the last day of each
March, June, September, and December and on the date such Reference Rate Advance shall be paid in
full.

     (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate
per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for
such Interest Period plus the Applicable Margin in effect from time to time, payable on the last
day of such Interest Period, and in the case of six-month Interest Periods, on the day which occurs
during such Interest Period three months from the first day of such Interest Period.

     (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each
Lender, so long as any such Lender shall be required under regulations of the Federal Reserve Board
to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency
Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of
such Lender, from the effective date of such Advance until such principal amount is paid in full,
at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the
Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing
such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of
such Lender for such Interest Period, payable on each date on which interest is payable on such
Advance. Such additional interest payable to any Lender shall be determined by such Lender and
notified to the Borrower through the Administrative Agent (such notice to include the calculation
of such additional interest, which calculation shall be conclusive in the absence of manifest
error).

     Section 2.07 Payments and Computations.

     (a) Payment Procedures. The Borrower shall make each payment under this Agreement and
under the Notes not later than 11:00 A.M. (New York City time) on the day when due in Dollars to
the Administrative Agent at the location referred to in the Notes (or such other location as the
Administrative Agent shall designate in writing to the Borrower) in same day funds without
deduction, setoff, or counterclaim of any kind. The Administrative Agent shall promptly thereafter
cause to be distributed like funds relating to the payment of principal, interest or fees ratably
(other than amounts payable solely to the Administrative Agent or a specific Lender pursuant to
Section 2.06(c), 2.09, 2.10, 2.11, 8.07, or 9.07, but after taking into account payments effected
pursuant to Section 9.04) in accordance with each Lender’s Pro Rata Share to the Lenders for the
account of their respective Applicable Lending Offices, and like funds relating to the payment of
any other amount payable to any Lender to such Lender for the account of its Applicable Lending
Office, in each case to be applied in accordance with the terms of this Agreement.

     (b) Computations. All computations of interest based on the Reference Rate and of
fees shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the
case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds
Rate shall be made by the Administrative Agent, on the basis of a year of 360 days, in each case
for the actual number of days (including the first day, but excluding the last day) occurring in
the period for which such interest or fees are payable. Each determination by the Administrative
Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest
error.

-23-

 

     (c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a
day other than a Business Day, such payment shall be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of payment of interest or
fees, as the case may be; provided, however, that if such extension would cause payment of interest
on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such
payment shall be made on the next preceding Business Day.

     (d) Administrative Agent Reliance. Unless the Administrative Agent shall have
received written notice from the Borrower prior to the date on which any payment is due to the
Lenders that the Borrower shall not make such payment in full, the Administrative Agent may assume
that the Borrower has made such payment in full to the Administrative Agent on such date and the
Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender
on such date an amount equal to the amount then due such Lender. If and to the extent the Borrower
shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to
the Administrative Agent forthwith on demand such amount distributed to such Lender, together with
interest, for each day from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Administrative Agent, at the Federal Funds Rate for such day.

     Section 2.08 Sharing of Payments, Etc. If any Lender shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on
account of the Advances made by it in excess of its Pro Rata Share of payments on account of the
Advances obtained by all the Lenders, such Lender shall notify the Administrative Agent and
forthwith purchase from the other Lenders such participations in the Advances made by them or held
by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably
with each of them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded
and such Lender shall repay to the purchasing Lender the purchase price to the extent of such
Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by
such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of
such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share
(according to the proportion of (i) the amount of such Lender’s required repayment to the
purchasing Lender to (ii) the total amount of all such required repayments to the purchasing
Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the
total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from
another Lender pursuant to this Section 2.08 may, to the fullest extent permitted by law, exercise
all its rights of payment (including the right of set-off) with respect to such participation as
fully as if such Lender were the direct creditor of the Borrower in the amount of such
participation.

     Section 2.09 Breakage Costs. If (a) any payment of principal of any Eurodollar Rate
Advance is made other than on the last day of the Interest Period for such Advance, whether as a
result of any payment pursuant to Section 2.04, the acceleration of the maturity of the Notes
pursuant to Article VII, or otherwise, or (b) the Borrower fails to make a principal or interest
payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable,
the Borrower shall, within 10 days of any written demand sent by any Lender to the Borrower through
the Administrative Agent, pay to the Administrative Agent for the account of such Lender any
amounts required to compensate such Lender for any additional losses, out-of-pocket costs or
expenses (including, without limitation, legal fees) which it may reasonably incur as a result of
such payment or nonpayment, including any loss (including loss of anticipated profits), cost or
expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired
by any Lender to fund or maintain such Advance.

     Section 2.10 Increased Costs.

-24-

 

     (a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change
(other than any change by way of imposition or increase of reserve requirements included in the
Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation or (ii)
the compliance with any guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the cost to any Lender of
agreeing to make or making, funding, or maintaining Eurodollar Rate Advances, then the Borrower
shall from time to time, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), immediately pay to the Administrative Agent for the account of such Lender
additional amounts sufficient to compensate such Lender for such increased cost. A certificate as
to the amount of such increased cost and detailing the calculation of such cost submitted to the
Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all
purposes, absent manifest error.

     (b) Capital Adequacy. If any Lender determines in good faith that compliance with any
law or regulation or any guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law) affects or would affect the amount of capital required or
expected to be maintained by such Lender or any corporation controlling such Lender and that the
amount of such capital is increased by or based upon the existence of such Lender’s commitment to
lend and other commitments of this type, then, upon 30 days’ prior written notice by such Lender
(with a copy of any such demand to the Administrative Agent), the Borrower shall immediately pay to
the Administrative Agent for the account of such Lender from time to time as specified by such
Lender, additional amounts sufficient to compensate such Lender, in light of such circumstances, to
the extent that such Lender reasonably determines such increase in capital to be allocable to the
existence of such Lender’s commitment to lend under this Agreement. A certificate as to such
amounts and detailing the calculation of such amounts submitted to the Borrower by such Lender
shall be conclusive and binding for all purposes, absent manifest error.

     Section 2.11 Taxes.

     (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be
made, in accordance with Section 2.07, free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities
with respect thereto, excluding, in the case of each Lender and the Administrative Agent, taxes
imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of
which such Lender or the Administrative Agent (as the case may be) is organized or any political
subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as “Taxes”) and, in the case of each
Lender, Taxes by the jurisdiction of such Lender’s Applicable Lending Office or any political
subdivision of such jurisdiction. If the Borrower shall be required by law to deduct any Taxes
from or in respect of any sum payable to any Lender or the Administrative Agent: (i) the sum
payable shall be increased as may be necessary so that, after making all required deductions
(including deductions applicable to additional sums payable under this Section 2.11), such Lender
or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made; provided, however, that if the Borrower’s obligation to
deduct or withhold Taxes is caused solely by such Lender’s or the Administrative Agent’s failure to
provide the forms described in Section 2.11(d) and such Lender or the Administrative Agent could
have provided such forms, no such increase shall be required; (ii) the Borrower shall make such
deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law.

     (b) Other Taxes. In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar levies which arise
from any

-25-

 

payment made or from the execution, delivery or registration of, or otherwise with respect to,
this Agreement, the Notes, or the other Loan Documents (hereinafter referred to as “Other Taxes”).

     (c) Indemnification. THE BORROWER INDEMNIFIES EACH LENDER AND THE ADMINISTRATIVE
AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING ANY TAXES OR OTHER TAXES IMPOSED BY
ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.11) PAID BY SUCH LENDER OR THE
ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING INTEREST AND EXPENSES)
ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY
OR LEGALLY ASSERTED. EACH PAYMENT REQUIRED TO BE MADE BY THE BORROWER IN RESPECT OF THIS
INDEMNIFICATION SHALL BE MADE TO THE ADMINISTRATIVE AGENT FOR THE BENEFIT OF ANY PARTY CLAIMING
SUCH INDEMNIFICATION WITHIN 30 DAYS FROM THE DATE THE BORROWER RECEIVES WRITTEN DEMAND THEREFOR
FROM THE ADMINISTRATIVE AGENT ON BEHALF OF ITSELF AS ADMINISTRATIVE AGENT OR ANY SUCH LENDER. IF
ANY LENDER OR THE ADMINISTRATIVE AGENT RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID BY THE
BORROWER UNDER THIS SECTION 2.11(C), SUCH LENDER OR THE ADMINISTRATIVE AGENT AS THE CASE MAY BE,
SHALL PROMPTLY PAY TO THE BORROWER THE BORROWER’S SHARE OF SUCH REFUND.

     (d) Foreign Lender Withholding Exemption. Each Lender that is not incorporated under
the laws of the United States of America or a state thereof agrees that it shall deliver to the
Borrower and the Administrative Agent (i) two duly completed copies of United States Internal
Revenue Service Form W8-ECI or W8-BEN or successor applicable form, as the case may be, certifying
in each case that such Lender is entitled to receive payments under this Agreement and the Notes
payable to it, without deduction or withholding of any United States federal income taxes, (ii) if
applicable, an Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the case
may be, to establish an exemption from United States backup withholding tax, and (iii) any other
governmental forms which are necessary or required under an applicable tax treaty or otherwise by
law to reduce or eliminate any withholding tax, which have been reasonably requested by the
Borrower. Each Lender which delivers to the Borrower and the Administrative Agent a Form W8-ECI or
W8-BEN and Form W-8 or W-9 pursuant to the next preceding sentence further undertakes to deliver to
the Borrower and the Administrative Agent two further copies of the said letter and Form W8-ECI or
W8-BEN and Form W-8 or W-9, or successor applicable forms, or other manner of certification, as the
case may be, on or before the date that any such letter or form expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent letter and form previously
delivered by it to the Borrower and the Administrative Agent, and such extensions or renewals
thereof as may reasonably be requested by the Borrower and the Administrative Agent certifying in
the case of a Form W8-ECI or W8-BEN that such Lender is entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income taxes. If an event
(including any change in treaty, law or regulation) has occurred prior to the date on which any
delivery required by the preceding sentence would otherwise be required which renders all such
forms inapplicable or which would prevent any Lender from duly completing and delivering any such
letter or form with respect to it and such Lender advises the Borrower and the Administrative Agent
that it is not capable of receiving payments without any deduction or withholding of United States
federal income tax, and in the case of a Form W-8 or W-9, establishing an exemption from United
States backup withholding tax, such Lender shall not be required to deliver such letter or forms.
The Borrower shall withhold tax at the rate and in the manner required by the laws of the United
States with respect to payments made to a Lender failing to timely provide the requisite Internal
Revenue Service forms.

obligation of the Borrower and any Guarantor which is a party to it enforceable against the
Borrower and each such Guarantor in accordance with its terms, except as such enforceability may be
limited by any applicable bankruptcy, insolvency, reorganization, moratorium, or similar law
affecting creditors’ rights generally and by general principles of equity.

     Section 4.05 Financial Statements.

     (a) The Borrower has delivered to the Administrative Agent and the Lenders copies of the
Financial Statements, and the Financial Statements are accurate and complete in all material
respects and present fairly the financial condition of the entities to which they pertain for the
periods indicated, in accordance with GAAP. As of the date of the Financial Statements, there were

information were furnished.

     Section 4.07 Litigation; Compliance with Laws.

     (a) There is no pending or, to the best knowledge of the Borrower, threatened action, suit, or
legal equitable, arbitrative or administrative proceeding affecting the Borrower or any of the
Guarantors before any court, Governmental Authority or arbitrator which could reasonably be
expected to cause a Material Adverse Change or which purports to affect the legality, validity,
binding effect or enforceability of this Agreement, any Note, or any other Loan Document.
Additionally, there is no pending or, to the best knowledge of the Borrower, threatened action,
suit, or legal equitable, arbitrative or administrative proceeding instituted against the Borrower
or any of the Guarantors which seeks to adjudicate the Borrower or any of the Guarantors as
bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment,
protection, relief, or composition of it or its debts under any law relating to bankruptcy,
insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or
the appointment of a receiver, trustee or other similar official for it or for any substantial part
of its Property.

     (b) The Borrower and its Subsidiaries have complied in all material respects with all material

used to purchase or carry any margin stock in violation of Regulation T, U or X.

     Section 4.09 Investment Company Act. Neither the Borrower nor any of the Guarantors
is an “investment company” or a company “controlled” by an “investment company” within the meaning
of the Investment Company Act of 1940, as amended.

consummation of the transactions contemplated by, the Loan Documents shall be or become subject to
regulation (a) under the Federal Power Act, as amended, (b) as a “public utility” or “public
service corporation” or the equivalent under the applicable law of any state, or (c) under the
applicable laws of any state relating to public utilities or public service corporations.

     Section 4.11 Taxes.

     (a) Reports and Payments. All Returns (as defined below in Section 4.11(c)) required
to be filed by or on behalf of the Borrower, the Guarantors, or any member of the Controlled Group
(hereafter collectively called the “Tax Group”) have been duly filed on a timely basis or
appropriate extensions have been obtained and such Returns are and will be true, complete and
correct, except where the failure to so file would not be reasonably expected to cause a Material
Adverse Change; and all Taxes shown to be payable on the Returns or on subsequent assessments with
respect thereto will have been paid in full on a timely basis, and no other Taxes will be payable
by the Tax Group with respect to items or periods covered by such Returns, except in each case to
the extent of (i) reserves reflected in the Financial Statements or (ii) taxes that are being
contested in good faith. The reserves for accrued Taxes reflected in

-31-

 

the financial statements delivered to the Lenders under this Agreement are adequate in the
aggregate for the payment of all unpaid Taxes, whether or not disputed, for the period ended as of
the date thereof and for any period prior thereto, and for which the Tax Group may be liable in its
own right, as withholding agent or as a transferee of the assets of, or successor to, any Person,
except for such Taxes or reserves therefor, the failure to pay or provide for which does not and
would not reasonably be expected to cause a Material Adverse Change.

     (b) Taxes Definition. “Taxes” in this Section 4.11 shall mean all taxes,
charges, fees, levies, or other assessments imposed by any federal, state, local, or foreign taxing
authority, including income, gross receipts, excise, real or personal property, sales, occupation,
use, service, leasing, environmental, value added, transfer, payroll, and franchise taxes (and
including any interest, penalties, or additions to tax attributable to or imposed on or with
respect to any such assessment).

     (c) Returns Definition. “Returns” in this Section 4.11 shall mean any
federal, state, local, or foreign report, estimate, declaration of estimated Tax, information
statement or return relating to, or required to be filed in connection with, any Taxes, including
any information return or report with respect to backup withholding or other payments of third
parties.

     Section 4.12 Pension Plans. All Plans are in compliance in all material respects with
all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan,
and each Plan has complied with and been administered in all material respects in accordance with
applicable provisions of ERISA and the Code. No “accumulated funding deficiency” (as defined in
Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of
the Code. No Reportable Event has occurred with respect to any Multiemployer Plan, and each
Multiemployer Plan has complied with and been administered in all material respects in accordance
with applicable provisions of ERISA and the Code. The present value of all benefits vested under
each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual
valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such
vested benefits. Neither the Borrower nor any member of the Controlled Group has had a complete or
partial withdrawal from any Multiemployer Plan for which there is any withdrawal liability. As of
the most recent valuation date applicable thereto, neither the Borrower nor any member of the
Controlled Group would become subject to any liability under ERISA if the Borrower or any member of
the Controlled Group has received notice that any Multiemployer Plan is insolvent or in
reorganization. Based upon GAAP existing as of the date of this Agreement and current factual
circumstances, the Borrower has no reason to believe that the annual cost during the term of this
Agreement to the Borrower or any member of the Controlled Group for post-retirement benefits to be
provided to the current and former employees of the Borrower or any member of the Controlled Group
under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the
aggregate, reasonably be expected to cause a Material Adverse Change.

     Section 4.13 Condition of Property; Casualties. Each of the Borrower and the
Guarantors has good and marketable title to all of its Properties as is customary in the oil and
gas industry in all material respects, free and clear of all Liens except for Permitted Liens. The
material Properties used or to be used in the continuing operations of the Borrower and each of the
Guarantors are in good repair, working order and condition, ordinary wear and tear excepted. Since
the date of the Financial Statements, neither the business nor the material Properties of the
Borrower and each of the Guarantors, taken as a whole, has been materially and adversely affected
as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or
other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts,
Permits, or concessions by a Governmental Authority, riot, activities of armed forces, or acts of
God or of any public enemy (whether or not covered by insurance).

     Section 4.14 No Burdensome Restrictions; No Defaults.

-32-

 

     (a) Neither the Borrower nor any Guarantor or any of their respective Subsidiaries is a party
to any indenture, loan, or credit agreement or any lease or other agreement or instrument or
subject to any charter or corporate restriction or provision of applicable law or governmental
regulation that could reasonably be expected to cause a Material Adverse Change. Neither the
Borrower nor any Guarantor or any of their respective Subsidiaries is in default under or with
respect to any contract, agreement, lease, or other instrument to which the Borrower or any
Guarantor or any of their respective Subsidiaries is a party and which could reasonably be expected
to cause a Material Adverse Change or under any agreement in connection with any Debt. Neither the
Borrower nor any Guarantor or any of their respective Subsidiaries has received any notice of
default under any material contract, agreement, lease, or other instrument to which the Borrower,
or Guarantor or any respective Subsidiary is a party.

     (b) No Default or Event of Default has occurred and is continuing.

     Section 4.15 Environmental Condition.

     (a) Permits, Etc. The Borrower and the Guarantors (i) have obtained all Environmental
Permits necessary for the ownership and operation of their respective Properties and the conduct of
their respective businesses; (ii) have at all times been and are in material compliance with all
terms and conditions of such Permits and with all other material requirements of applicable
Environmental Laws; (iii) have not received notice of any material violation or alleged violation
of any Environmental Law or Permit; and (iv) are not subject to any actual or contingent
Environmental Claim, which could reasonably be expected to cause a Material Adverse Change.

     (b) Certain Liabilities. To the Borrower’s actual knowledge, none of the present or
previously owned or operated Property of the Borrower or any Guarantor or of any of their former
Subsidiaries, wherever located: (i) has been placed on or proposed to be placed on the National
Priorities List, the Comprehensive Environmental Response Compensation Liability Information System
list, or their state or local analogs, or have been otherwise investigated, designated, listed, or
identified as a potential site for removal, remediation, cleanup, closure, restoration,
reclamation, or other response activity under any Environmental Laws; (ii) is subject to a Lien,
arising under or in connection with any Environmental Laws, that attaches to any revenues or to any
Property owned or operated by the Borrower or any Guarantor or any of their respective
Subsidiaries, wherever located, which could reasonably be expected to cause a Material Adverse
Change; or (iii) has been the site of any Release of Hazardous Substances or Hazardous Wastes from
present or past operations which has caused at the site or at any third-party site any condition
that has resulted in or could reasonably be expected to result in the need for Response that would
cause a Material Adverse Change.

     (c) Certain Actions. Without limiting the foregoing: (i) all necessary notices have
been properly filed, and no further action is required under current Environmental Law as to each
Response or other restoration or remedial project undertaken by the Borrower or the Guarantors or
any of their former Subsidiaries on any of their presently or formerly owned or operated Property
and (ii) the present and, to the Borrower’s best knowledge, future liability, if any, of the
Borrower and the Guarantors which could reasonably be expected to arise in connection with
requirements under Environmental Laws will not result in a Material Adverse Change.

     Section 4.16 Permits, Licenses, Etc. The Borrower and the Guarantors possess all
authorizations, Permits, licenses, patents, patent rights or licenses, trademarks, trademark
rights, trade name rights and copyrights which are material to the conduct of their business. No
Person is in violation in any material respect of the terms under which it possesses such
intellectual property or the right to use such intellectual property. The Borrower and the
Guarantors manage and operate their business in all material respects in accordance with all
applicable Legal Requirements and good industry practices.

-33-

 

     Section 4.17 Gas Contracts. Neither the Borrower nor any of the Guarantors, as of the
date hereof: (a) is obligated in any material respect by virtue of any prepayment made under any
contract containing a “take-or-pay” or “prepayment” provision or under any similar agreement to
deliver hydrocarbons produced from or allocated to any of the Borrower’s and its Subsidiaries’ Oil
and Gas Properties at some future date without receiving full payment therefor at the time of
delivery, or (b) except as has been disclosed to the Administrative Agent, has produced gas, in any
material amount, subject to, and none of the Borrower’s and the Guarantors’ Oil and Gas Properties

Security Instruments will have been made, obtained and taken in all relevant jurisdictions. All
leases and agreements for the conduct of business of the Borrower and the Guarantors are valid and
subsisting, in full force and effect and there exists no default or event of default or
circumstance which with the giving of notice or lapse of time or both would give rise to a default
under any such leases or agreements which could reasonably be expected to cause a Material Adverse
Change. Neither the Borrower nor any of the Guarantors is a party to any agreement or arrangement
(other than this Agreement and the Security Instruments), or subject to any order, judgment, writ
or decree, which either restricts or purports to restrict its ability to grant Liens to secure the
Obligations against their respective assets or Properties.

     Section 4.19 Solvency and Insurance. Before and after giving effect to the making of
the Advances, the Borrower is, and each Guarantor is, Solvent. Additionally, each of the Borrower
and its Subsidiaries carry insurance required under Section 5.02.

     Section 4.20 Hedging Agreements. Schedule 4.20 sets forth, as of the date hereof, a
true and complete list of all Interest Hedge Agreements, Hydrocarbon Hedge Agreements, and any
other Hedge Contract of the Borrower and each Guarantor, the material terms thereof (including the

market value thereof, all credit support agreements relating thereto (including any margin required
or supplied), and the counterparty to each such agreement.

ARTICLE V

AFFIRMATIVE COVENANTS

     So long as any Note or any amount under any Loan Document shall remain unpaid, or any Lender
shall have any Commitment hereunder, the Borrower agrees, unless the Required Lenders shall
otherwise consent in writing, to comply with the following covenants:

     Section 5.01 Compliance with Laws, Etc. The Borrower shall comply, and cause each of
its Subsidiaries to comply, in all material respects with all Legal Requirements. Without limiting
the generality and coverage of the foregoing, the Borrower shall comply, and shall cause each of
its Subsidiaries to comply, in all material respects, with all Environmental Laws and all laws,
regulations, or directives with respect to equal employment opportunity and employee safety in all
jurisdictions in which the Borrower, or any of its Subsidiaries do business; provided, however,
that this Section 5.01 shall not prevent the Borrower or any of its Subsidiaries from, in good
faith and with reasonable diligence, contesting the validity or application of any such laws or
regulations by appropriate legal proceedings. Without limitation of the foregoing, the Borrower
shall, and shall cause each of its Subsidiaries to, (a) maintain and possess all authorizations,
Permits, licenses, trademarks, trade names, rights and copyrights which are necessary to the
conduct of its business and (b) obtain, as soon as practicable, all consents or approvals required
from any states of the United States (or other Governmental Authorities) necessary to grant the
Administrative Agent an Acceptable Security Interest in the Borrower’s and its Subsidiaries’ Oil
and Gas Properties.

     Section 5.02 Maintenance of Insurance.

     (a) The Borrower shall, and shall cause each of its Subsidiaries to, procure and maintain or
shall cause to be procured and maintained continuously in effect policies of insurance in form and
amounts and issued by companies, associations or organizations reasonably satisfactory to the
Administrative Agent covering such casualties, risks, perils, liabilities and other hazards as is
customary in the industry. In addition, the Borrower shall, and shall cause each of its
Subsidiaries to, comply with all requirements regarding insurance contained in the Security
Instruments.

     (b) The Borrower shall deliver to the Administrative Agent copies of certificates of
insurance, and endorsements and renewals thereof, that are required herein. All policies of
insurance shall either have attached thereto a Lender’s mortgagee loss payable endorsement for the
benefit of the First Lien Administrative Agent, as mortgagee loss payee in form reasonably
satisfactory to the Administrative Agent or shall name the Administrative Agent as an additional
insured, as applicable. The Borrower shall furnish the Administrative Agent with a certificate of
insurance or a certified copy of all policies of insurance required. All policies or certificates
of insurance shall set forth the coverage, the limits of liability, the name of the carrier, the
policy number, and the period of coverage. All policies of insurance required under the terms
hereof shall contain an endorsement or agreement by the insurer that any loss shall be payable in
accordance with the terms of such policy notwithstanding any act of negligence of the Borrower, or
a Subsidiary or any party holding under the Borrower or a Subsidiary which might otherwise result
in a forfeiture of the insurance and the further agreement of the insurer waiving all rights of
setoff, counterclaim or deductions against the Borrower and its Subsidiaries. All such policies
shall contain a provision that notwithstanding any contrary agreements between the Borrower, its
Subsidiaries, and the applicable insurance company, such policies will not be canceled,

-35-

 

allowed to lapse without renewal, surrendered or amended (which provision shall include any
reduction in the scope or limits of coverage) without at least 30 days’ prior written notice to the
Administrative Agent. In the event that, notwithstanding the “mortgagee’s loss payable
endorsement” requirement of this Section 5.02, the proceeds of any insurance policy described above
are paid to the Borrower or Subsidiaries and any Obligations are outstanding and the First Lien
Debt has been indefeasibly paid in full, the Borrower shall deliver such proceeds to the
Administrative Agent immediately upon receipt.

     Section 5.03 Preservation of Corporate Existence, Etc. The Borrower shall preserve
and maintain, and cause each of its Subsidiaries to preserve and maintain, its corporate or limited
liability company, as applicable, existence, rights, franchises, and privileges in the jurisdiction
of its incorporation or organization, as applicable, and qualify and remain qualified, and cause
each such Subsidiary to qualify and remain qualified, as a foreign entity in each jurisdiction in
which qualification is necessary or desirable in view of its business and operations or the
ownership of its Properties, and, in each case, where failure to qualify or preserve and maintain
its rights and franchises could reasonably be expected to cause a Material Adverse Change.

     Section 5.04 Payment of Taxes, Etc. The Borrower shall pay and discharge, and cause
each of its Subsidiaries to pay and discharge, before the same shall become delinquent, (a) all
taxes, assessments, and governmental charges or levies imposed upon it or upon its income or
profits or Property that are material in amount, prior to the date on which penalties attach
thereto and (b) all lawful claims that are material in amount which, if unpaid, might by law become
a Lien upon its Property; provided, however, that neither the Borrower nor any such Subsidiary
shall be required to pay or discharge any such tax, assessment, charge, levy, or claim which is
being contested in good faith and by appropriate proceedings, and with respect to which reserves in
conformity with GAAP have been provided.

     Section 5.05 Visitation Rights; Books and Records. The Borrower shall keep proper
books of records and account in which full, true and correct entries in conformity with GAAP and
all Legal Requirements shall be made of all dealings and transactions in relation to its business
and activities. At any reasonable time and from time to time, upon reasonable notice, the Borrower
shall, and shall cause its Subsidiaries to, permit the Administrative Agent and any Lender or any
of their respective agents or representatives thereof, to (a) examine and make copies of and
abstracts from the records and books of account of, and visit and inspect at their reasonable
discretion the Properties of, the Borrower and any such Subsidiary, and (b) discuss the affairs,

specified in such clauses, the Administrative Agent may, based on the information available to it,
estimate in good faith the Total Present Value from time to time thereafter until the
Administrative Agent and the Lenders receive the relevant Independent Engineering Report, Internal
Engineering Report, or other information, as applicable. Such estimated Total Present Value shall
thereupon be used for the purposes of Section 6.20(a) until a new Total Present Value is calculated
or estimated pursuant to this Agreement.

     Section 6.21 Other Debt. Except as otherwise permitted by the terms of the
Intercreditor Agreement neither the Borrower nor any of its Subsidiaries shall amend, supplement or
otherwise modify the terms of (i) the First Lien Debt or (ii) any other Debt permitted by Section

6.02(b) and (y) with respect to Debt described in clause (ii) hereof, amendments, supplements or
other modification that do not require a consent fee and extend the maturity or reduce the amount
of any payment of principal thereof or reduce the rate or extend any date for payment of interest
thereon.

     Section 6.22 2008 Long-Term Incentive Plan. The Borrower shall not, and shall not

Debt owed to, the Borrower or any Subsidiary of the Borrower, (b) make loans or advances to, or
other investments in, the

-48-

 

Borrower or any other Subsidiary of the Borrower or (c) transfer any of its assets to the
Borrower or any other Subsidiary of the Borrower, except for such encumbrances or restrictions
existing under or by reason of (i) any restrictions existing under the Loan Documents and (ii) any
restrictions with respect to a Subsidiary imposed pursuant to an agreement that has been entered

ARTICLE VIII

THE ADMINISTRATIVE AGENT

     Section 8.01 Appointment. Each Lender hereby irrevocably designates and appoints the
Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents,
and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to take
such action on its behalf under the provisions of this Agreement and the other Loan Documents and
to exercise such powers and perform such duties as are expressly delegated to the Administrative
Agent by the terms of this Agreement and the other Loan Documents, together with such other powers
as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, the Administrative Agent shall not have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any Lender, 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.

     Section 8.02 Delegation of Duties. The Administrative Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The
Administrative Agent shall not be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

     Section 8.03 Exculpatory Provisions. Neither the Administrative Agent nor any of its
officers, directors, employees, agents, advisors, attorneys-in-fact or affiliates shall be (i)
liable for any action lawfully taken or omitted to be taken by it or such Person under or in
connection with this Agreement or any other Loan Document (except to the extent that any of the
foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to
have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii)
responsible in any manner to any of the Lenders for any recitals, statements, representations or
warranties made by any Loan Party or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document referred to or provided
for in, or received by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party a
party thereto to perform its obligations hereunder or thereunder. The Administrative Agent shall
not be under any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this Agreement or any other
Loan Document, or to inspect the properties, books or records of any Loan Party.

     Section 8.04 Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely, and shall be fully protected in relying, upon any instrument, writing,
resolution, notice, consent, certificate, affidavit, letter, telecopy or email message, statement,
order or other document or conversation believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons and upon advice and statements of legal
counsel (including counsel to the Borrower), independent accountants and other experts selected by
the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the
owner thereof for all purposes unless a written notice of assignment, negotiation or transfer
thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be
fully justified in failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if
so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and expense that may
be incurred by it by reason of taking or continuing to take any such action. The Administrative
Agent shall

-53-

 

in all cases be fully protected in acting, or in refraining from acting, under this Agreement
and the other Loan Documents in accordance with a request of the Required Lenders (or, if so
specified by this Agreement, all Lenders), and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

     Section 8.05 Notice of Default. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative
Agent has received notice from a Lender or the Borrower referring to this Agreement, describing
such Default or Event of Default and stating that such notice is a “notice of default”. In the
event that the Administrative Agent receives such a notice, the Administrative Agent shall give
notice thereof to the Lenders. The Administrative Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so
specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Lenders.

     Section 8.06 Non-Reliance on Administrative Agent and Other Lenders. Each Lender
expressly acknowledges that neither the Administrative Agent nor any of its officers, directors,
employees, agents, advisors, attorneys-in-fact or affiliates have made any representations or
warranties to it and that no act by the Administrative Agent hereafter taken, including any review
of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties and their affiliates and
made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also
represents that it will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such investigation as it deems
necessary to inform itself as to the business, operations, property, financial and other condition
and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and
other documents expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of any Loan Party or any affiliate of a
Loan Party that may come into the possession of the Administrative Agent or any of its officers,
directors, employees, agents, advisors, attorneys-in-fact or affiliates.

     Section 8.07 Indemnification. The Lenders agree to indemnify the Administrative Agent
and its officers, directors, employees, affiliates, agents, advisors and controlling persons (each,
an “Agent Indemnitee”) (to the extent not reimbursed by the Borrower and without limiting
the obligation of the Borrower to do so), ratably according to their respective Pro Rata Share in
effect on the date on which indemnification is sought under this Section (or, if indemnification is
sought after the date upon which the Commitments shall have terminated and the Loans shall have
been paid in full, ratably in accordance with such Pro Rata Share immediately prior to such date),
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever
that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by
or asserted against such Agent Indemnitee in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby or any action
taken or

-54-

 

omitted by such Agent Indemnitee under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements that are found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from such Agent Indemnitee’s gross negligence or willful misconduct.
The agreements in this Section shall survive the payment of the Loans and all other amounts payable
hereunder.

     Section 8.08 Agent in Its Individual Capacity. The Administrative Agent and its
affiliates may make loans to, accept deposits from and generally engage in any kind of business
with any Loan Party as though it were not an Administrative Agent. With respect to its Loans made
or renewed by it, the Administrative Agent shall have the same rights and powers under this
Agreement and the other Loan Documents as any Lender and may exercise the same as though it were
not the Administrative Agent, and the terms “Lender” and “Lenders” shall include each Agent in its
individual capacity.

     Section 8.09 Successor Administrative Agent. The Administrative Agent may resign as
Administrative Agent upon 10 days’ notice to the Lenders and the Borrower. If the Administrative
Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then
the Required Lenders shall appoint from among the Lenders or their Affiliates a successor agent for
the Lenders, which successor agent shall (unless an Event of Default under Section 7.01(a) or
Section 7.01(e) with respect to the Borrower shall have occurred and be continuing) be subject to
approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon
such successor agent shall succeed to the rights, powers and duties of the Administrative Agent,
and the term “Administrative Agent” shall mean such successor agent effective upon such appointment
and approval, and the former Administrative Agent’s rights, powers and duties as Administrative
Agent shall be terminated, without any other or further act or deed on the part of such former
Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no
successor agent has accepted appointment as Administrative Agent by the date that is 10 days
following a retiring Administrative Agent’s notice of resignation, the retiring Administrative
Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and
perform all of the duties of the Administrative Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above. After any retiring
Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 8 and of
Section 9.5 shall continue to inure to its benefit.

ARTICLE IX

MISCELLANEOUS

     Section 9.01 Amendments, Etc. (a) No amendment or waiver of any provision of this
Agreement, the Notes, or any other Loan Document, nor consent to any departure by the Borrower or
any Subsidiary therefrom, shall in any event be effective unless the same shall be in writing and
signed by the Required Lenders and the Borrower, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given; provided, however, that no

following: (a) waive any of the conditions specified in Section 3.01, (b) increase the Commitments
of the Lenders, (c) reduce the principal of, or interest on, the Notes or any fees or other amounts

any of them to take any action hereunder or under any other Loan Document, (f) amend Section 2.08,
Section 7.06 or this Section 9.01, (g) amend

-55-

 

the definition of “Required Lenders,” (h) release any
Guarantor from its obligations under any Guaranty, except in connection with a transaction
expressly permitted by Section 6.04 (i) permit the Borrower or any Subsidiary to enter into any
merger or consolidation with or into any other Person that is not expressly permitted by Section
6.04(a), or amend Section 6.04(a), (j) release any Collateral securing the Obligations, except for
releases of Collateral sold as permitted by this Agreement, or (k) amend or waive any provision of,
nor consent to any departure by any party thereto from, the Intercreditor Agreement, and provided,
further, that no amendment, waiver or consent shall, unless in writing and signed by the
Administrative Agent in addition to the Lenders required above to take such action, affect the
rights or duties of the Administrative Agent under this Agreement or any other Loan Document.

     (b) In connection with any proposed amendment, supplement, modification, waiver or
termination (a “Proposed Change”) requiring the consent of all affected Lenders, if the
consent of the holders of more than 75% of the sum of the aggregate unpaid principal amount of the
Loans then outstanding to such Proposed Change is obtained, but the consent to such Proposed Change
of other Lenders whose consent is required is not obtained (any such Lender whose consent is not
obtained as described in this Section (b) being referred to as a “Non-Consenting Lender”),
then, at any Borrower’s request, any assignee that is reasonably acceptable to the Administrative
Agent (and that is not a Non-Consenting Lender) shall have the right, with the prior consent of the
Administrative Agent (which consent shall not be unreasonably withheld or delayed), to purchase
from such Non-Consenting Lender, and such Non-Consenting Lender agrees that it shall, upon such
Borrower’s request, sell and assign to such assignee, at no expense to such Non-Consenting Lender
(including with respect to any processing and recordation fees that may be applicable pursuant to
Section 9.06(a), which shall be paid by the assignee or the Borrower), all the Loans of such
Non-Consenting Lender for an amount equal to the principal balance of all Loans held by such
Non-Consenting Lender and all accrued interest, fees and other amounts with respect thereto through
the date of sale (including amounts under Sections 2.04, 2.09, 2.10 and 2.11), such purchase and
sale to be consummated pursuant to an executed Assignment and Acceptance in accordance with Section
9.06 (which Assignment and Acceptance need not be signed by such Non-Consenting Lender).

     Section 9.02 Notices, Etc. All notices and other communications shall be in writing
(including telecopy or facsimile) and mailed by certified mail, return receipt requested,
telecopied, faxed, hand delivered, or delivered by a nationally recognized overnight courier, at
the address for the appropriate party specified in Schedule I or at such other address as shall be
designated by such party in a written notice to the other parties. All such notices and
communications shall, when so mailed, telecopied, or hand delivered or delivered by a nationally
recognized overnight courier, be effective when received if mailed, when telecopy transmission is
completed, or when delivered by such messenger or courier, respectively, except that notices and
communications to the Administrative Agent pursuant to Article II or VIII shall not be effective
until received by the Administrative Agent.

     Section 9.03 No Waiver; Remedies. No failure on the part of any Lender, the
Administrative Agent to exercise, and no delay in exercising, any right hereunder or under any Note
shall operate as a waiver thereof; nor shall any single or partial exercise of any such right
preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

     Section 9.04 Costs and Expenses. The Borrower agrees to pay on demand (a) all
reasonable out-of-pocket costs and expenses of the Administrative Agent in connection with the
preparation, execution, delivery, administration, modification, and amendment of this Agreement,
the Notes, the Guaranties, and the other Loan Documents including the reasonable fees and
out-of-pocket expenses of counsel for the Administrative Agent with respect to advising the
Administrative Agent as to its rights and responsibilities under this Agreement, and (b) all
out-of-pocket costs and expenses, if any, of the

Administrative Agent and each Lender (including
reasonable counsel fees and expenses of the Administrative Agent and each Lender) in connection
with the enforcement (whether through negotiations, legal proceedings, or otherwise) of this
Agreement, the Notes, the Guaranties, and the other Loan Documents.

     Section 9.05 Binding Effect. This Agreement shall become effective when it shall have
been executed by the Borrower and the Administrative Agent, and when the Administrative Agent shall
have, as to each Lender, either received a counterpart hereof executed by such Lender or been
notified by such Lender that such Lender has executed it and thereafter shall be binding upon and
inure to the benefit of the Borrower, the Administrative Agent and each Lender and their respective
successors and assigns, except that the Borrower shall not have the right to assign its rights or
delegate its duties under this Agreement or any interest in this Agreement without the prior
written consent of each Lender.

     Section 9.06 Lender Assignments and Participations.

     (a) Assignments. Any Lender may assign to one or more banks or other entities all or
any portion of its rights and obligations under this Agreement; provided, however, that (i) each
such assignment shall be of a constant, and not a varying, percentage of such Lender’s rights and
obligations assigned under this Agreement, (ii) the amount of Advances of such Lender being
assigned pursuant to each such assignment (determined as of the date of the Assignment and
Acceptance with respect to such assignment) shall be, if to an entity other than a Lender, not less
than $1,000,000.00, (iii) each such assignment shall be to an Eligible Assignee, (iv) the parties
to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance
and recording in the Register, an Assignment and Acceptance, together with the Notes subject to
such assignment, and (v) each Eligible Assignee (other than the Eligible Assignee of the
Administrative Agent) shall pay to the Administrative Agent a $3,500 administrative fee. Upon such
execution, delivery, acceptance and recording, from and after the effective date specified in each
Assignment and Acceptance, which effective date shall be at least three Business Days after the
execution thereof, (A) the assignee thereunder shall be a party hereto for all purposes and, to the
extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment
and Acceptance, have the rights and obligations of a Lender hereunder and (B) such Lender
thereunder shall, to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or
the remaining portion of such Lender’s rights and obligations under this Agreement, such Lender
shall cease to be a party hereto).

     (b) Terms of Assignments. By executing and delivering an Assignment and Acceptance,
the Lender thereunder and the assignee thereunder confirm to and agree with each other and the
other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance,
such Lender makes no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this Agreement or the
execution, legality, validity, enforceability, genuineness, sufficiency of value of this Agreement
or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no
representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrower or its Subsidiaries or
the performance or observance by the Borrower or its Subsidiaries of any of their obligations under
this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of the Financial
Statements referred to in Section 4.05 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such Assignment and
Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative
Agent, such Lender or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action
under this Agreement; (v) such assignee appoints and

-57-

 

authorizes the Administrative Agent to take
such action as agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance
with their terms all of the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

     (c) The Register. The Administrative Agent shall maintain at its address referred to
in Section 9.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the Commitments of, and
principal amount of the Advances owing to, each Lender from time to time (the “Register”).
The entries in the Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name
is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by the Borrower or any Lender at any reasonable time and from
time to time upon reasonable prior notice.

     (d) Procedures. Upon its receipt of an Assignment and Acceptance executed by a Lender
and an Eligible Assignee, together with the Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form
of the attached Exhibit A: (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register, and (iii) give prompt notice thereof to the Borrower. Within
five Business Days after its receipt of such notice, the Borrower shall execute and deliver to the
Administrative Agent in exchange for the surrendered Notes (A) a new Note to the order of such
Eligible Assignee in an amount equal to the Advances purchased by it pursuant to such Assignment
and Acceptance and (B) if such Lender has retained any portion of the Advances owing to it, a new
Note to the order of such Lender in an amount equal to the portion retained by it hereunder. Such
new Notes shall be dated the effective date of such Assignment and Acceptance and shall otherwise
be in substantially the form of the attached Exhibit D.

     (e) Participations. Each Lender may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under this Agreement (including
all or a portion of the Advances owing to it and the Notes held by it); provided, however, 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,
(iii) such Lender shall remain the holder of any such Notes for all purposes of this Agreement,
(iv) the Borrower, the Administrative Agent, and the other Lenders shall continue to deal solely
and directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement, and (v) such Lender shall not require the participant’s consent to any matter under this
Agreement, except for change in the principal amount of the Notes, reductions in fees or interest,
releasing all or substantially all of any Collateral, permitting the Borrower or any Subsidiary to
enter into any merger or consolidation with or into any other, postponement of any date fixed for
any payment of principal of, or interest on, the Notes or any fees or other amounts payable
hereunder, or extensions of the Maturity Date. The Borrower hereby agrees that
participants shall have the same rights under Sections 2.09, 2.10, 2.11(c), and 9.07 as a
Lender to the extent of their respective participations.

     Section 9.07 Indemnification. THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE AGENT,
THE LENDERS AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AND
AGENTS FROM, AND DISCHARGE, RELEASE, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES,
LIABILITIES, CLAIMS, OR DAMAGES WHICH MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST THEM IN
ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY ACTION TAKEN OR OMITTED BY THEM

-58-

 

UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (INCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES,
OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED’S OWN NEGLIGENCE OR STRICT LIABILITY)
AND INCLUDING ENVIRONMENTAL LIABILITIES, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS,
DAMAGES, OR EXPENSES INCURRED BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON
TO BE INDEMNIFIED, AS DETERMINED BY A COURT OF COMPETENT JURISDICTION IN A FINAL AND NONAPPEALABLE
JUDGMENT.

     Section 9.08 Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and
the same agreement. Delivery of an executed counterpart signature page of this Agreement by
facsimile is as effective as executing and delivering this Agreement in the presence of the other
parties to this Agreement.

     Section 9.09 Survival of Representations, Etc. All representations and warranties
contained in this Agreement or made in writing by or on behalf of the Borrower in connection
herewith shall survive the execution and delivery of this Agreement and the Loan Documents, the
making of the Advances and any investigation made by or on behalf of the Lenders, none of which
investigations shall diminish any Lender’s right to rely on such representations and warranties.
All obligations of the Borrower provided for in Sections 2.09, 2.10, 2.11(c), 9.04, and 9.07 and
all of the obligations of the Lenders in Section 8.07 shall survive any termination of this
Agreement and repayment in full of the Obligations.

     Section 9.10 Severability. In case one or more provisions of this Agreement or the
other Loan Documents shall be invalid, illegal or unenforceable in any respect under any applicable
law, the validity, legality, and enforceability of the remaining provisions contained herein or
therein shall not be affected or impaired thereby.

     Section 9.11 [Reserved].

RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     (b) The Borrower hereby irrevocably and unconditionally:

     (i) submits for itself and its property in any legal action or proceeding relating to this
Agreement and the other Loan Documents to which it is a party, or for the recognition and
enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the
courts of the State of New
York, the courts of the United States for the Southern District of New York, and appellate
courts from any thereof;

     (ii) consents that any such action or proceeding may be brought in such courts and waives any
objection that it may now or hereafter have to the venue of any such action or proceeding in any
such court or that such action or proceeding was brought in an inconvenient court and agrees not to

     (iii) agrees that service of process in any such action or proceeding may be effected by
mailing a copy thereof by registered or certified mail (or any substantially similar form of mail),
postage prepay, to

-59-

 

the Borrower at its address set forth on Schedule I or at such other address of
which the Administrative Agent shall have been notified pursuant to the terms of this Agreement;

     (iv) agrees that nothing herein shall affect the right to effect service of process in any
other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

     (v) waives, to the maximum extent not prohibited by law, any right it may have to claim or
recover in any legal action or proceeding referred to in this Section any special, exemplary,
punitive or consequential damages.

     Section 9.13 USA Patriot Act. Each Lender that is subject to the Patriot Act and the
Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record

Intercreditor Agreement will be made available to each Lender on the Effective Date and thereafter
upon request. Each Lender acknowledges and agrees to the terms of such Intercreditor Agreement and
agrees that the terms thereof shall be binding on such Lender and its successors and assigns, as if
it were a party thereto.

     Section 9.16 WAIVER OF JURY TRIAL. THE BORROWER, THE LENDERS, AND THE ADMINISTRATIVE
AGENT HEREBY ACKNOWLEDGE THAT THEY HAVE BEEN REPRESENTED BY AND HAVE CONSULTED WITH COUNSEL OF
THEIR CHOICE, AND HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY WAIVE ANY AND ALL
RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT, ANY OTHER LOAN DOCUMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

     Section 9.17 ORAL AGREEMENTS. THIS WRITTEN AGREEMENT AND THE LOAN DOCUMENTS, AS
DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

	$                    
	 	                    , 2008

     For value received, the undersigned Crusader Energy Group Inc., a Nevada corporation
(“Borrower”), hereby promises to pay to the order of                                         
(“Bank”), the principal amount of                                          Dollars ($                               
         ) or, if
less, the aggregate outstanding principal amount of the Advances (as defined in the Credit
Agreement referred to below) made by the Bank to the Borrower, together with interest on the unpaid
principal amount of the Advances from the date of such Advances until such principal amount is paid
in full, at such interest rates, and at such times, as are specified in the Credit Agreement.

     This Note is one of the Notes referred to in, and is entitled to the benefits of, and is
subject to the terms of, the Second Lien Credit Agreement dated as of July 17, 2008 (as the same
may be amended, restated, supplemented or modified from time to time, the “Credit

JPMorgan Chase Bank, N.A., as administrative agent for the Lenders (the “Administrative
Agent”). Capitalized terms used in this Note that are defined in the Credit Agreement and not
otherwise defined in this Note have the meanings assigned to such terms in the Credit Agreement.
The Credit Agreement, among other things, (a) provides for the making of the Advances by the Bank
to the Borrower in an aggregate amount not to exceed at any time outstanding the Dollar amount
first above mentioned, the indebtedness of the Borrower resulting from each such Advance being
evidenced by this Note and (b) contains provisions for acceleration of the maturity of this Note
upon the happening of certain events stated in the Credit Agreement and for optional and mandatory
prepayments of principal prior to the maturity of this Note upon the terms and conditions specified
in the Credit Agreement.

     This Note is also subject to the terms and provisions of the Intercreditor Agreement dated as
of July 17, 2008 (as the same may be modified from time to time, the “Intercreditor
Agreement”), among the Borrower, the Guarantors, the Administrative Agent, the Lenders, the
First Lien Lenders, and Union Bank of California, N.A., as administrative agent for the First Lien
Lenders.

     Both principal and interest are payable in lawful money of the United States of America to the
Administrative Agent at the place and in the manner specified in the Credit Agreement. The Bank
shall record payments of principal made under this Note, but no failure of the Bank to make such
recordings shall affect the Borrower’s repayment obligations under this Note.

     Without being limited thereto or thereby, this Note is secured by the Security Instruments and
guaranteed under the Guaranties.

     Except as specifically provided in the Credit Agreement, the Borrower hereby waives
presentment, demand, protest, notice of intent to accelerate, notice of acceleration, and any other
notice of any kind. No failure to exercise, and no delay in exercising, any rights hereunder on
the part of the holder of this Note shall operate as a waiver of such rights.

and certain other credit parties as described in the Mortgage, which Mortgage has been recorded in

Mortgage is enclosed. The properties covered by the Mortgage include all of the oil, gas and other
hydrocarbons and/or other minerals attributable to the above-referenced Contract to which we

letter is to notify you that, commencing immediately upon the receipt hereof, and in accordance
with the terms and conditions of the Mortgage, you are to deliver all proceeds attributable to the
