Lenders” and individually, a “Term Lender”), and BANK OF AMERICA, N.A., as
Administrative Agent.

PRELIMINARY STATEMENTS:

     Pursuant to the Merger Agreement dated as of June 7, 2008 (the “Merger Agreement”)
among the Parent, Hermes Acquisition Corp., a Virginia corporation (the “Acquisition
Subsidiary”), and Hilb Rogal & Hobbs Company, a Virginia corporation (the “Acquired
Company”), the Parent, the Acquired Company, and the Acquisition Subsidiary have agreed to
consummate a merger (the “Merger”) in which the Acquired Company will be merged with and

     The Parent and the Borrower have requested that the Term Lenders provide to the Borrower a

cash consideration for their shares in the Acquired Company, (ii) to pay transaction fees and
expenses related to the Merger and (iii) to refinance the Existing Material Indebtedness (defined
below).

     In furtherance of the foregoing, the Term Lenders are willing to make available the term loan
facility on the terms and subject to the conditions set forth herein. In consideration of the
mutual covenants and agreements herein contained, the parties hereto covenant and agree as follows:

pursuant to this subclause (ix) for any period shall not exceed 5% of the amount of Consolidated
EBITDA computed in accordance with this definition for such period, and (B) the Indebtedness and

in determining such portion of Consolidated Net Income, (i) any extraordinary gains and
non-recurring gains for such period, (ii) any non-cash gains for such period and (iii) any gains on
asset sales outside the ordinary course of business for such period, all determined on a
consolidated basis for such Pro Forma Entity in accordance with GAAP.

or indirectly through one or more intermediaries, Controls or is Controlled by or is under common
Control with the Person specified.

2

 

     “Applicable Rate” means, from time to time, the following percentages per annum, based

	Level	 	S&P/Moody’s	 	Rate+	 	 	Rate+	 
	1	 	BBB-/Baa3 or better
	 	 	225.0	 	 	 	125.0	 
	2	 	BBB-/Ba1
	 	 	275.0	 	 	 	175.0	 
	 	 	or

Debt Ratings issued by foregoing rating agencies differ by one level, other than as expressly
provided in Pricing Level 2 above, then the Pricing Level for the higher of such Debt Ratings shall

applicable) most recently in effect prior to such change or cessation shall be employed in
determining the Applicable Rate.

     Initially, the Applicable Rate shall be determined based upon the Debt Rating specified in the
certificate delivered pursuant to Section 4.01(a)(ix)(A). Thereafter, each change in the
Applicable Rate resulting from a publicly announced change in the Debt Rating (other than as a
result of a change in the rating system of S&P or Moody’s) shall be effective during the period
commencing on the date of the public announcement thereof, irrespective of when notice of such
change shall have been furnished by the Borrower to the Administrative Agent and the Term Lenders
pursuant to Section 6.01(f) or otherwise, and ending on the date immediately preceding the
effective date of the next such change.

THE COMMITMENTS AND BORROWINGS

     2.01 The Term Loan Borrowing. Subject to the terms and conditions set forth herein, each Term
Lender severally agrees to make a single loan in Dollars to the Borrower on the Closing Date in an
amount not to exceed such Term Lender’s Term Loan Commitment. The Term Loan Borrowing shall
consist of Term Loans made simultaneously by the Term Lenders in accordance with their respective
Applicable Percentage of the Term Loan Facility. After the funding of the Term Loans on the
Closing Date, the Term Loan Commitments shall terminate,

23

 

and amounts borrowed under this Section 2.01(a) and repaid or prepaid may not be
reborrowed. Term Loans may be Base Rate Loans or Eurocurrency Rate Loans, as further provided
herein.

     2.02 Term Loan Borrowing, Conversions and Continuations of Term Loans.

     (a) The Term Loan Borrowing, each conversion of Term Loans from one Type to the other, and
each continuation of Eurocurrency Rate Loans shall be made upon the Borrower’s irrevocable notice
to the Administrative Agent, which may be given by telephone. Each such notice must be received by
the Administrative Agent not later than 11:00 a.m. (i) three Business Days prior to the requested
date of the Term Loan Borrowing of, conversion to or continuation of Eurocurrency Rate Loans or of
any conversion of Eurocurrency Rate Loans to Base Rate Loans, and (ii) one Business Day prior to
the requested date of the Term Loan Borrowing of Base Rate Loans. Each telephonic notice by the
Borrower pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the
Administrative Agent of a written Term Loan Notice, appropriately completed and signed by a
Responsible Officer of the Borrower. Each of the Term Loan Borrowing of, conversion to or
continuation of Eurocurrency Rate Loans or Base Rate Loans shall be in a principal amount of
$5,000,000 or a whole multiple of $1,000,000 in excess thereof.

     (b) Each Term Loan Notice (whether telephonic or written) shall specify (i) whether the
Borrower is requesting the Term Loan Borrowing, a conversion of Term Loans from one Type to the
other, or a continuation of Eurocurrency Rate Loans, (ii) the requested date of the Term Loan
Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii)
the principal amount of Term Loans to be borrowed, converted or continued, (iv) the Type of Term
Loans to be borrowed or to which existing Term Loans are to be converted, and (v) if applicable,
the duration of the Interest Period with respect thereto. If the Borrower fails to specify a Type
of Term Loan in a Term Loan Notice or if the Borrower fails to give a timely notice requesting a
conversion or continuation, then the applicable Term Loans shall be made as, or converted to, Base
Rate Loans. Any automatic conversion to Base Rate Loans shall be effective as of the last day of
the Interest Period then in effect with respect to the applicable Eurocurrency Rate Loans. If the
Borrower requests the Term Loan Borrowing of, conversion to, or continuation of Eurocurrency Rate
Loans in any such Term Loan Notice, but fails to specify an Interest Period, it will be deemed to
have specified an Interest Period of one month.

     (c) Following receipt of a Term Loan Notice, the Administrative Agent shall promptly notify
each Term Lender of the amount of its Applicable Percentage of the Term Loans, and if no timely
notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall
notify each Term Lender of the details of any automatic conversion to Base Rate Loans as described
in the preceding subsection. In the case of the Term Loan Borrowing, each Term Lender shall make
the amount of its Term Loan available to the Administrative Agent in Same Day Funds at the
Administrative Agent’s Office not later than 1:00 p.m. on the Business Day specified in the Term
Loan Notice. Upon satisfaction of the applicable conditions set forth in Section 4.01, the
Administrative Agent shall make all funds so received available to the Borrower in like funds as
received by the Administrative Agent either by (i) crediting the account of the Borrower on the
books of Bank of America with the amount of

24

 

such funds or (ii) wire transfer of such funds, in each case in accordance with instructions
provided to (and reasonably acceptable to) the Administrative Agent by the Borrower.

     (d) Except as otherwise provided herein, a Eurocurrency Rate Loan may be continued or
converted only on the last day of an Interest Period for such Eurocurrency Rate Loan. During the
existence of a Default, no Term Loans may be requested as, converted to or continued as
Eurocurrency Rate Loans without the consent of the Required Lenders.

     (e) The Administrative Agent shall promptly notify the Borrower and the Term Lenders of the
interest rate applicable to any Interest Period for Eurocurrency Rate Loans upon determination of
such interest rate. At any time that Base Rate Loans are outstanding, the Administrative Agent
shall notify the Borrower and the Term Lenders of any change in Bank of America’s prime rate used
in determining the Base Rate promptly following the public announcement of such change.

     (f) After giving effect to the Term Loan Borrowing and all continuations of Term Loans, there
shall not be more than four Interest Periods in effect in respect of the Term Loan Facility.

     (g) Notwithstanding anything in this Section 2.02 to the contrary, if the Borrower
desires to borrow any or all of the Term Loans pursuant to the Term Loan Borrowing as Eurocurrency
Loans, the Borrower shall have delivered to the Administrative Agent for the benefit of the Term
Lenders at least three Business Days prior to the Closing Date a funding indemnity letter in form
and substance reasonably satisfactory to the Administrative Agent addressing matters substantially
the same as those set forth in Section 3.05.

time voluntarily prepay Term Loans in whole or in part without premium or penalty; provided
that (i) such notice must be received by the Administrative Agent not later than 11:00 a.m. (A)
three Business Days prior to any date of prepayment of Eurocurrency Rate Loans, and (B) one
Business Day prior to the date of prepayment of Base Rate Loans; and (ii) any prepayment of Term
Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess
thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such
notice shall specify the date and amount of such prepayment and the Type(s) of Term Loans to be
prepaid and, if Eurocurrency Rate Loans are to be prepaid, the Interest Period(s) of such Term
Loans. The Administrative Agent will promptly notify each applicable Term Lender of its receipt of
each such notice, and of the amount of such Term Lender’s ratable portion of such prepayment (based
on such Term Lender’s Applicable Percentage in respect of the Term Loan Facility). If such notice
is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified
in such notice shall be due and payable on the date specified therein. Any prepayment of a
Eurocurrency Rate Loan shall be accompanied by all accrued interest on the amount prepaid, together
with any additional amounts required pursuant to Section 3.05. Each prepayment of the

Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder

Percentage of the Term Loan Facility, an amount equal to 0.50% times the Total Outstandings

the Base Rate is determined by Bank of America’s “prime rate” shall be made on the basis of a year
of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees
and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in
more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year).
Interest shall accrue on each Term Loan for the day on which the Term Loan is made, and shall not
accrue on a Term Loan, or any portion thereof, for the day on which the Term Loan or such portion
is paid; provided that any Term Loan that is repaid on the same day on which it is made
shall, subject to Section 2.09(a), bear interest for one day. Each determination by the
Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all
purposes, absent manifest error.

     2.08 Evidence of Debt. The Term Loans made by each Term Lender shall be evidenced by one or
more accounts or records maintained by such Term Lender and by the Administrative Agent in the
ordinary course of business. The accounts or records maintained by the Administrative Agent and
each Term Lender shall be conclusive absent manifest error of the amount of the Term Loans made by
the Term Lenders to the Borrower and the interest and payments thereon. Any failure so to record
or any error in doing so shall not, however, limit or

27

 

otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect
to the Obligations. In the event of any conflict between the accounts and records maintained by
any Term Lender and the accounts and records of the Administrative Agent in respect of such
matters, the accounts and records of the Administrative Agent shall control in the absence of
manifest error. Upon the request of any Term Lender made through the Administrative Agent, the
Borrower shall execute and deliver to such Term Lender (through the Administrative Agent) a Term
Loan Note, which shall evidence such Term Lender’s Term Loans in addition to such accounts or
records. Each Term Lender may attach schedules to a Term Loan Note and endorse thereon the date,
Type (if applicable), amount and maturity of its Term Loans and payments with respect thereto.

     2.09 Payments Generally; Administrative Agent’s Clawback. (a) General. All payments
to be made by the Borrower shall be made without condition or deduction for any counterclaim,
defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the
Borrower hereunder shall be made to the Administrative Agent, for the account of the respective
Term Lenders to which such payment is owed, at the applicable Administrative Agent’s Office in
Dollars and in Same Day Funds not later than 2:00 p.m. on the date specified herein. Without
limiting the generality of the foregoing, the Administrative Agent may require that any payments
due under this Agreement be made in the United States. The Administrative Agent will promptly
distribute to each Term Lender its Applicable Percentage in respect of the Term Loan Facility (or
other applicable share as provided herein) of such payment in like funds as received by wire
transfer to such Term Lender’s Lending Office. All payments received by the Administrative Agent
after 2:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable
interest or fee shall continue to accrue. If any payment to be made by the Borrower shall come due
on a day other than a Business Day, payment shall be made on the next following Business Day, and
such extension of time shall be reflected in computing interest or fees, as the case may be.

     (b) (i) Funding by Term Lenders; Presumption by Administrative Agent. Unless the
Administrative Agent shall have received notice from a Term Lender prior to the proposed date of
the Term Loan Borrowing of Eurocurrency Rate Loans (or, in the case of the Term Loan Borrowing of
Base Rate Loans, prior to 12:00 noon on the date of the Term Loan Borrowing) that such Term Lender
will not make available to the Administrative Agent such Term Lender’s share of such Term Loan
Borrowing, the Administrative Agent may assume that such Term Lender has made such share available
on such date in accordance with Section 2.02 (or, in the case of a Term Loan Borrowing of
Base Rate Loans, that such Term Lender has made such share available in accordance with and at the
time required by Section 2.02) and may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. In such event, if a Term Lender has not in fact made its
share of the Term Loan Borrowing available to the Administrative Agent, then the applicable Term
Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such
corresponding amount in Same Day Funds with interest thereon, for each day from and including the
date such amount is made available to the Borrower to but excluding the date of payment to the
Administrative Agent, at (A) in the case of a payment to be made by such Term Lender, the Overnight
Rate, plus any administrative, processing or similar fees customarily charged by the
Administrative Agent in connection with the foregoing, and (B) in the case of a payment to be made
by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Term
Lender shall pay

28

 

such interest to the Administrative Agent for the same or an overlapping period, the
Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by such
Borrower for such period. If such Term Lender pays its share of the Term Loan Borrowing to the
Administrative Agent, then the amount so paid shall constitute such Term Lender’s Term Loan
included in such Term Loan Borrowing. Any payment by the Borrower shall be without prejudice to
any claim the Borrower may have against a Term Lender that shall have failed to make such payment
to the Administrative Agent.

     (ii) Payments by Borrower; Presumptions by Administrative Agent. Unless the
Administrative Agent shall have received notice from the Borrower prior to the date on which
any payment is due to the Administrative Agent for the account of the Term Lenders hereunder
that the Borrower will not make such payment, the Administrative Agent may assume that the
Borrower has made such payment on such date in accordance herewith and may, in reliance upon
such assumption, distribute to the appropriate Term Lenders the amount due. In such event,
if the Borrower has not in fact made such payment, then each of the applicable Term Lenders
severally agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Term Lender, in Same Day Funds with interest thereon, for each day from
and including the date such amount is distributed to it to but excluding the date of payment
to the Administrative Agent, at the Overnight Rate.

     A notice of the Administrative Agent to any Term Lender or to the Borrower with respect to any
amount owing under this subsection (b) shall be conclusive, absent manifest error.

     (c) Failure to Satisfy Conditions Precedent. If any Term Lender makes available to
the Administrative Agent funds for any Term Loan to be made by such Term Lender as provided in the
foregoing provisions of this Article II, and such funds are not made available to the
Borrower by the Administrative Agent because the conditions to the Term Loan Borrowing set forth in
Article IV are not satisfied or waived in accordance with the terms hereof, the
Administrative Agent shall promptly return such funds (in like funds as received from such Term
Lender) to such Term Lender, without interest.

     (d) Obligations of Term Lenders Several. The obligations of the Term Lenders
hereunder to make Term Loans and to make payments pursuant to Section 10.04(c), are several
and not joint. The failure of any Term Lender to make any Term Loan or to make any payment under
Section 10.04(c) on any date required hereunder shall not relieve any other Term Lender of
its corresponding obligation to do so on such date, and no Term Lender shall be responsible for the
failure of any other Term Lender to so make its Term Loan or to make its payment under Section
10.04(c).

     (e) Funding Source. Nothing herein shall be deemed to obligate any Term Lender to
obtain the funds for any Term Loan in any particular place or manner or to constitute a
representation by any Term Lender that it has obtained or will obtain the funds for any Term Loan
in any particular place or manner.

     2.10 Sharing of Payments by Term Lenders. If any Term Lender shall, by exercising any right
of setoff or counterclaim or otherwise, obtain payment in respect of (a)

29

 

Obligations in respect of the Term Loan Facility due and payable to such Term Lender hereunder
and under the other Loan Documents at such time in excess of its ratable share (according to the
proportion of (i) the amount of such Obligations due and payable to such Term Lender at such time
to (ii) the aggregate amount of the Obligations in respect of the Term Loan Facility due and
payable to all Term Lenders hereunder and under the other Loan Documents at such time) of payments
on account of the Obligations in respect of the Term Loan Facility due and payable to all Term
Lenders hereunder and under the other Loan Documents at such time obtained by all the Term Lenders
at such time or (b) Obligations in respect of any of the Term Loan Facility owing (but not due and
payable) to such Term Lender hereunder and under the other Loan Documents at such time in excess of
its ratable share (according to the proportion of (i) the amount of such Obligations owing (but not
due and payable) to such Term Lender at such time to (ii) the aggregate amount of the Obligations
in respect of the Term Loan Facility owing (but not due and payable) to all Term Lenders hereunder
and under the other Loan Parties at such time) of payment on account of the Obligations in respect
of the Term Loan Facility owing (but not due and payable) to all Term Lenders hereunder and under
the other Loan Documents at such time obtained by all of the Term Lenders at such time then the
Term Lender receiving such greater proportion shall (x) notify the Administrative Agent of such
fact, and (y) purchase (for cash at face value) participations in the Term Loans of the other Term
Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such
payments shall be shared by the Term Lenders ratably in accordance with the aggregate amount of
Obligations in respect of the Term Loan Facility then due and payable to the Term Lenders or owing
(but not due and payable) to the Term Lenders, as the case may be; provided that:

     (i) if any such participations or subparticipations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations or
subparticipations shall be rescinded and the purchase price restored to the extent of such
recovery, without interest; and

     (ii) the provisions of this Section shall not be construed to apply to (A) any payment
made by a Borrower pursuant to and in accordance with the express terms of this Agreement or
(B) any payment obtained by a Term Lender as consideration for the assignment of or sale of
a participation in any of its Term Loans to any assignee or participant, other than to the
Borrower or any Subsidiary thereof (as to which the provisions of this Section shall apply).

     The Borrower consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Term Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to
such participation as fully as if such Term Lender were a direct creditor of the Borrower in the
amount of such participation.

     2.11 Determination of Eurocurrency Rate. If with respect to any determination of the
Eurocurrency Rate the Administrative Agent determines (which determination shall be conclusive
absent manifest error) that BBA LIBOR will not be available on a Quotation Day using Reuters or
another commercially available source providing quotations of BBA LIBOR, the Administrative Agent
shall promptly request that each Reference Bank supply it with its Quoted Rate, and the
Eurocurrency Rate to be used to determine the interest rate applicable to

30

 

the relevant Term Loan Borrowing, conversion or continuation shall be the average of the
Quoted Rates supplied to the Administrative Agent by the Reference Banks. If the Administrative
Agent makes such request and one or more Reference Banks fails to supply its Quoted Rate to the
Administrative Agent by 11:30 a.m., London time, on a Quotation Day, the applicable Eurocurrency
Rate shall (subject to Section 3.03(b)) be determined on the basis of the Quoted Rates
supplied by the remaining Reference Banks.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 Taxes.

     (a) Payments Free of Taxes; Obligation to Withhold; Payments on Account of Taxes. (i)
Any and all payments by or on account of any obligation of the Borrower hereunder or under any
other Loan Document shall to the extent permitted by applicable Laws be made free and clear of and
without reduction or withholding for any Taxes. If, however, applicable Laws require the Borrower
or the Administrative Agent to withhold or deduct any Tax, such Tax shall be withheld or deducted
in accordance with such Laws as determined by the Borrower or the Administrative Agent, as the case
may be, upon the basis of the information and documentation to be delivered pursuant to subsection
(e) below.

     (ii) If the Borrower or the Administrative Agent shall be required by the Code to
withhold or deduct any Taxes, including both United States Federal backup withholding and
withholding taxes, from any payment, then (A) the Administrative Agent shall withhold or
make such deductions as are determined by the Administrative Agent to be required based upon
the information and documentation it has received pursuant to subsection (e) below, (B) the
Administrative Agent shall timely pay the full amount withheld or deducted to the relevant
Governmental Authority in accordance with the Code, and (C) to the extent that the
withholding or deduction is made on account of Indemnified Taxes or Other Taxes, the sum
payable by the Borrower shall be increased as necessary so that after any required
withholding or the making of all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent or Term Lender, as the
case may be, receives an amount equal to the sum it would have received had no such
withholding or deduction been made.

     (iii) If the Borrower or the Administrative Agent shall be required by any applicable
Laws other than the Code to withhold or deduct any Taxes from any payment, then (A) the
Borrower or the Administrative Agent, as required by such Laws, shall withhold or make such
deductions as are determined by it to be required based upon the information and
documentation it has received pursuant to subsection (e) below, (B) the Borrower or the
Administrative Agent, to the extent required by such Laws, shall timely pay the full amount
so withheld or deducted by it to the relevant Governmental Authority in accordance with such
Laws, and (C) to the extent that the withholding or deduction is made on account of
Indemnified Taxes or Other Taxes, the sum payable by the Borrower

31

 

shall be increased as necessary so that after any required withholding or the making of
all required deductions (including deductions applicable to additional sums payable under
this Section) the Administrative Agent or Term Lender, as the case may be, receives an
amount equal to the sum it would have received had no such withholding or deduction been
made.

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

     (c) Tax Indemnifications. (i) Without limiting the provisions of subsection (a) or
(b) above, the Borrower shall, and does hereby, indemnify the Administrative Agent and each Term
Lender, and shall make payment in respect thereof within ten days after written demand therefor,
for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other
Taxes imposed or asserted on or attributable to amounts payable under this Section) withheld or
deducted by the Borrower or the Administrative Agent or paid by the Administrative Agent or such
Term Lender, as the case may be, and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority. The Borrower
shall also, and does hereby, indemnify the Administrative Agent, and shall make payment in respect
thereof within ten days after written demand therefor, for any amount which a Term Lender for any
reason fails to pay indefeasibly to the Administrative Agent as required by clause (ii) of this
subsection. A certificate as to the amount of any such payment or liability delivered to the
Borrower by a Term Lender (with a copy to the Administrative Agent), or by the Administrative Agent
on its own behalf or on behalf of a Term Lender, shall be conclusive absent manifest error.

     (ii) Without limiting the provisions of subsection (a) or (b) above, each Term Lender
shall, and does hereby, indemnify the Borrower and the Administrative Agent, and shall make
payment in respect thereof within ten days after demand therefor, against any and all Taxes
and any and all related losses, claims, liabilities, penalties, interest and expenses
(including the fees, charges and disbursements of any counsel for the Borrower or the
Administrative Agent) incurred by or asserted against the Borrower or the Administrative
Agent by any Governmental Authority as a result of the failure by such Term Lender to
deliver, or as a result of the inaccuracy, inadequacy or deficiency of, any documentation
required to be delivered by such Term Lender to the Borrower or the Administrative Agent
pursuant to subsection (e). Each Term Lender hereby authorizes the Administrative Agent to
set off and apply any and all amounts at any time owing to such Term Lender under this
Agreement or any other Loan Document against any amount due to the Administrative Agent
under this clause (ii). The agreements in this clause (ii) shall survive the resignation
and/or replacement of the Administrative Agent, any assignment of rights by, or the
replacement of, a Term Lender, the termination of the Term Loan Commitments and the
repayment, satisfaction or discharge of all other Obligations.

     (d) Evidence of Payments. Upon request by a Borrower or the Administrative Agent, as
the case may be, after any payment of Taxes by the Borrower or by the Administrative Agent

32

 

to a Governmental Authority as provided in this Section 3.01, the Borrower shall
deliver to the Administrative Agent or the Administrative Agent shall deliver to the Borrower, as
the case may be, the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of any return required by Laws to report such payment or
other evidence of such payment reasonably satisfactory to the Borrower or the Administrative Agent,
as the case may be.

     (e) Status of Term Lenders; Tax Documentation. (i) Each Term Lender shall deliver to
the Borrower and to the Administrative Agent, at the time or times prescribed by applicable Laws or
when reasonably requested by the Borrower or the Administrative Agent, such properly completed and
executed documentation prescribed by applicable Laws or by the taxing authorities of any
jurisdiction and such other reasonably requested information as will permit the Borrower or the
Administrative Agent, as the case may be, to determine (A) whether or not payments made hereunder
or under any other Loan Document are subject to Taxes, (B) if applicable, the required rate of
withholding or deduction, and (C) such Term Lender’s entitlement to any available exemption from,
or reduction of, applicable Taxes in respect of all payments to be made to such Term Lender by the
Borrower pursuant to this Agreement or otherwise to establish such Term Lender’s status for
withholding tax purposes in the applicable jurisdictions.

     (ii) Without limiting the generality of the foregoing, if a Borrower is resident for tax
purposes in the United States,

     (A) any Term Lender that is a “United States person” within the meaning of
Section 7701(a)(30) of the Code shall deliver to the Borrower and the Administrative
Agent executed originals of Internal Revenue Service Form W-9 or such other
documentation or information prescribed by applicable Laws or reasonably requested
by the Borrower or the Administrative Agent as will enable the Borrower or the
Administrative Agent, as the case may be, to determine whether or not such Term
Lender is subject to backup withholding or information reporting requirements; and

     (B) each Foreign Lender that is entitled under the Code or any applicable
treaty to an exemption from or reduction of withholding tax with respect to payments
hereunder or under any other Loan Document shall deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the
recipient) on or prior to the date on which such Foreign Lender becomes a Term
Lender under this Agreement (and from time to time thereafter upon the request of
the Borrower or the Administrative Agent, but only if such Foreign Lender is legally
entitled to do so), whichever of the following is applicable:

     (I) executed originals of Internal Revenue Service Form W-8BEN claiming
eligibility for benefits of an income tax treaty to which the United States
is a party,

     (II) executed originals of Internal Revenue Service Form W-
8ECI,

33

 

     (III) executed originals of Internal Revenue Service Form W-8IMY and
all required supporting documentation,

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

     (V) executed originals of any other form prescribed by applicable Laws
as a basis for claiming exemption from or a reduction in United States
Federal withholding tax together with such supplementary documentation as
may be prescribed by applicable Laws to permit the Borrower or the
Administrative Agent to determine the withholding or deduction required to
be made.

     (iii) Each Term Lender shall promptly (A) notify the Borrower and the Administrative
Agent of any change in circumstances which would modify or render invalid any claimed
exemption or reduction, and (B) take such steps as shall not be materially disadvantageous
to it, in the reasonable judgment of such Term Lender, and as may be reasonably necessary
(including the re-designation of its Lending Office) to avoid any requirement of applicable
Laws of any jurisdiction that the Borrower or the Administrative Agent make any withholding
or deduction for taxes from amounts payable to such Term Lender.

     (iv) The Borrower shall promptly deliver to the Administrative Agent or any Term
Lender, as the Administrative Agent or such Term Lender shall reasonably request, on or
prior to the Closing Date (or such later date on which it first becomes a Borrower), and in
a timely fashion thereafter, such documents and forms required by any relevant taxing
authorities under the Laws of any jurisdiction, duly executed and completed by the Borrower,
as are required to be furnished by such Term Lender or the Administrative Agent under such
Laws in connection with any payment by the Administrative Agent or any Term Lender of Taxes
or Other Taxes, or otherwise in connection with the Loan Documents, with respect to such
jurisdiction.

     (f) Treatment of Certain Refunds. Unless required by applicable Laws, at no time
shall the Administrative Agent have any obligation to file for or otherwise pursue on behalf of a
Term Lender, or have any obligation to pay to any Term Lender, any refund of Taxes withheld or
deducted from funds paid for the account of such Term Lender, as the case may be. If the
Administrative Agent or any Term Lender determines, in its sole discretion, that it has received a
refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with
respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay

34

 

to the Borrower an amount equal to such refund (but only to the extent of indemnity payments
made, or additional amounts paid, by the Borrower under this Section with respect to the Taxes or
Other Taxes giving rise to such refund), net of all out-of-pocket expenses and net of any loss or
gain realized in the conversion of such funds from or to another currency incurred by the
Administrative Agent or such Term Lender, as the case may be, and without interest (other than any
interest paid by the relevant Governmental Authority with respect to such refund); provided
that the Borrower, upon the request of the Administrative Agent or such Term Lender, agrees to
repay the amount paid over to the Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent or such Term Lender in
the event the Administrative Agent or such Term Lender is required to repay such refund to such
Governmental Authority. This subsection shall not be construed to require the Administrative Agent
or any Term Lender to make available its tax returns (or any other information relating to its
taxes that it deems confidential) to the Borrower or any other Person.

     3.02 Illegality. If any Term Lender determines that any Law has made it unlawful, or that any
Governmental Authority has asserted that it is unlawful, for any Term Lender or its applicable
Lending Office to make, maintain or fund Eurocurrency Rate Loans, or to determine or charge
interest rates based upon the Eurocurrency Rate, or any Governmental Authority has imposed material
restrictions on the authority of such Term Lender to purchase or sell, or to take deposits of,
Dollars in the applicable interbank market, then, on notice thereof by such Term Lender to the
Borrower through the Administrative Agent, any obligation of such Term Lender to make or continue
Eurocurrency Rate Loans or to convert Base Rate Loans to Eurocurrency Rate Loans, shall be
suspended until such Term Lender notifies the Administrative Agent and the Borrower that the
circumstances giving rise to such determination no longer exist. Upon receipt of such notice, the
Borrower shall, upon demand from such Term Lender (with a copy to the Administrative Agent), either
prepay or, if applicable, convert all Eurocurrency Rate Loans of such Term Lender to Base Rate
Loans, either on the last day of the Interest Period therefor, if such Term Lender may lawfully
continue to maintain such Eurocurrency Rate Loans to such day, or immediately, if such Term Lender
may not lawfully continue to maintain such Eurocurrency Rate Loans. Upon any such prepayment or
conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted.

     3.03 Inability to Determine Rates.

     (a) If the Required Lenders determine that for any reason in connection with any request for a
Eurocurrency Rate Loan or a conversion to or continuation thereof that (i) Dollar deposits are not
being offered to banks in the London interbank eurodollar market for the applicable amount and
Interest Period of such Eurocurrency Rate Loan, (ii) adequate and reasonable means do not exist for
determining the Eurocurrency Rate for any requested Interest Period with respect to a proposed
Eurocurrency Rate Loan, or (iii) the Eurocurrency Rate for any requested Interest Period with
respect to a proposed Eurocurrency Rate Loan does not adequately and fairly reflect the cost to
such Term Lenders of funding such Eurocurrency Rate Loan, the Administrative Agent will promptly so
notify the Borrower and each Term Lender. Thereafter, the obligation of the Term Lenders to make
or maintain Eurocurrency Rate Loans shall be suspended until the Administrative Agent (upon the
instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the
Borrower may revoke any pending request for the Term Loan Borrowing of, conversion to or
continuation of Eurocurrency Rate Loans or, failing

35

 

that, will be deemed to have converted such request into a request for the Term Loan Borrowing
of (or conversion to) Base Rate Loans in the amount specified therein.

     (b) Without limitation of the provisions of Section 3.03(a), if, with respect to any
Term Loan Borrowing, conversion or continuation for which the Eurocurrency Rate is to be determined
by reference to the Quoted Rates supplied to the Administrative Agent by the Reference Banks in
accordance with Section 2.11, (i) fewer than two Reference Banks supply the Administrative
Agent with a Quoted Rate or (ii) prior to the close of business on the Quotation Day, the
Administrative Agent receives notification from Term Lenders whose participation in such Term Loan
Borrowing, conversion or continuation exceeds 35% of the amount of such Term Loan Borrowing,
conversion or continuation that the cost to such Term Lenders of obtaining matching deposits in the
London interbank market would be in excess of the Eurocurrency Rate for the relevant Interest
Period, then the Administrative Agent shall give notice thereof to the Parent, the Borrower and the
Lenders in writing as promptly as practicable thereafter, and the interest rate applicable to such
Term Loan Borrowing, conversion or continuation shall be the Base Rate plus the Applicable Rate.

     3.04 Increased Costs; Reserves on Eurocurrency Rate Loans.

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

     (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, any Term Lender (except (A) any reserve
requirement contemplated by Section 3.04(e) and (B) the requirements of the Bank of
England and the Financial Services Authority or the European Central Bank reflected in the
Mandatory Cost, other than as set forth below);

     (ii) subject any Term Lender to any tax of any kind whatsoever with respect to this
Agreement or any Eurocurrency Rate Loan made by it, or change the basis of taxation of
payments to such Term Lender in respect thereof (except for Indemnified Taxes or Other Taxes
covered by Section 3.01 and the imposition of, or any change in the rate of, any
Excluded Tax payable by such Term Lender);

     (iii) result in the failure of the Mandatory Cost, as calculated hereunder, to
represent the cost to any Term Lender of complying with the requirements of the Bank of
England and/or the Financial Services Authority or the European Central Bank in relation to
its making, funding or maintaining Eurocurrency Rate Loans; or

     (iv) impose on any Term Lender or the London interbank market any other condition, cost
or expense affecting this Agreement or Eurocurrency Rate Loans made by such Term Lender;

and the result of any of the foregoing shall be to increase the cost to such Term Lender of making
or maintaining any Eurocurrency Rate Loan (or of maintaining its obligation to make any such Term
Loan), or to reduce the amount of any sum received or receivable by such Term Lender hereunder
(whether of principal, interest or any other amount) then, upon request of such

36

 

Term Lender, the Borrower will pay to such Term Lender such additional amount or amounts as will
compensate such Term Lender for such additional costs incurred or reduction suffered.

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

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

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

     (e) Additional Reserve Requirements. The Borrower shall pay to each Term Lender, (i)
as long as such Term Lender shall be required to maintain reserves with respect to liabilities or
assets consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency
liabilities”), additional interest on the unpaid principal amount of each Eurocurrency Rate Loan
equal to the actual costs of such reserves allocated to such Term Loan by such Term Lender (as
determined by such Term Lender in good faith, which determination shall be conclusive), and (ii) as
long as such Term Lender shall be required to comply with any reserve ratio requirement or
analogous requirement of any other central banking or financial regulatory authority imposed in
respect of the maintenance of the Term Loan Commitments or the funding of the Eurocurrency Rate
Loans, such additional costs (expressed as a percentage per annum and rounded upwards, if
necessary, to the nearest five decimal places) equal to the actual costs allocated to such Term
Loan Commitment or Term Loan by such Term Lender (as determined by such Term Lender in good faith,
which determination shall be conclusive), which in each case shall be due and payable on each date
on which interest is payable on such Term Loan; provided the Borrower shall have received
at least ten days’ prior notice (with a copy to

37

 

the Administrative Agent) of such additional interest or costs from such Term Lender. If a
Term Lender fails to give notice ten days prior to the relevant Interest Payment Date, such
additional interest or costs shall be due and payable ten days from receipt of such notice.

     3.05 Compensation for Losses. Upon demand of any Term Lender (with a copy to the
Administrative Agent) from time to time, the Borrower shall promptly compensate such Term Lender
for and hold such Term Lender harmless from any loss, cost or expense incurred by it as a result
of:

     (a) any continuation, conversion, payment or prepayment of any Term Loan other than a Base
Rate Loan on a day other than the last day of the Interest Period for such Term Loan (whether
voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

     (b) any failure by the Borrower (for a reason other than the failure of such Term Lender to
make a Term Loan) to prepay, borrow, continue or convert any Term Loan other than a Base Rate Loan
on the date or in the amount notified by the Borrower;

     (c) any assignment of a Eurocurrency Rate Loan on a day other than the last day of the
Interest Period therefor as a result of a request by the Borrower pursuant to Section
10.13;

including any foreign exchange losses and any loss or expense arising from the liquidation or
reemployment of funds obtained by it to maintain such Term Loan, from fees payable to terminate the
deposits from which such funds were obtained or from the performance of any foreign exchange
contract. The Borrower shall also pay any customary administrative fees charged by such Term
Lender in connection with the foregoing.

     For purposes of calculating amounts payable by the Borrower to the Term Lenders under this
Section 3.05, each Term Lender shall be deemed to have funded each Eurocurrency Rate Loan
made by it at the Eurocurrency Rate for such Term Loan by a matching deposit or other borrowing in
the offshore interbank market for Dollars for a comparable amount and for a comparable period,
whether or not such Eurocurrency Rate Loan was in fact so funded.

     3.06 Mitigation Obligations; Replacement of Term Lenders.

     (a) Designation of a Different Lending Office. If any Term Lender requests
compensation under Section 3.04, or the Borrower is required to pay any additional amount
to any Term Lender or any Governmental Authority for the account of any Term Lender pursuant to
Section 3.01, or if any Term Lender gives a notice pursuant to Section 3.02, then
such Term Lender shall, as applicable, use reasonable efforts to designate a different Lending
Office for funding or booking its Term Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment of such Term
Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to
Section 3.01 or 3.04, as the case may be, in the future, or eliminate the need for
the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would not
subject such Term Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Term Lender. The Borrower hereby agrees to pay all reasonable costs and
expenses incurred by any Term Lender in connection with any such designation or assignment.

38

 

     (b) Replacement of Term Lenders. If any Term Lender requests compensation under
Section 3.04, or if the Borrower is required to pay any additional amount to any Term
Lender or any Governmental Authority for the account of any Term Lender pursuant to Section
3.01, the Borrower may replace such Term Lender in accordance with Section 10.13.

     3.07 Survival. All of the Borrower’s obligations under this Article III shall survive
termination of the Term Loan Commitments, repayment of all other Obligations hereunder, and
resignation of the Administrative Agent.

ARTICLE V.

REPRESENTATIONS AND WARRANTIES

     Each of the Parent and the Borrower represents and warrants to the Administrative Agent and
the Term Lenders (each such representation and warranty expressly being made on the date of this
Agreement whether or not the accuracy thereof is a condition to the making of the Term Loan
Borrowing pursuant to Section 4.01) that:

     5.01 Organization; Powers. Each of the Parent and its Subsidiaries is duly organized, validly
existing and in good standing under the Laws of the jurisdiction of its organization, has all
requisite power and authority to carry on its business as now conducted and, except where the
failure to do so, individually or in the aggregate, could not reasonably be expected to result in a
Material Adverse Effect, is qualified to do business in, and is in good standing in, every
jurisdiction where such qualification is required.

     5.02 Authorization; Enforceability. The Transactions to be entered into by each Loan Party
are within such Loan Party’s corporate powers and have been duly authorized by all necessary
corporate and, if required, stockholder action. This Agreement has been duly executed and
delivered by the Parent and the Borrower and constitutes, and each other Loan Document to which any
Loan Party is to be a party, when executed and delivered by such Loan Party, will constitute, a
legal, valid and binding obligation of the Parent, the Borrower or such other Loan Party (as the
case may be), enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and
subject to general principles of equity, regardless of whether considered in a proceeding in equity
or at law.

     5.03 Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or
approval of, registration or filing with, or any other action by, any Governmental Authority,
except such as have been obtained or made and are in full force and effect, (b) will not violate
any material applicable Law or the charter, by-laws or other Organization Documents of the Parent
or any Subsidiary or any order of any Governmental Authority, (c) will not violate or result in a
default under any material indenture, agreement or other material instrument binding upon the
Parent or any Subsidiary or its assets, or give rise to a right thereunder to require any payment
to be made by the Parent or any Subsidiary, and (d) will not result in the creation or imposition
of any Lien on any asset of the Parent or any Subsidiary pursuant to the terms of such material
indenture, agreement or other material instrument.

     5.04 Financial Condition; No Material Adverse Change.

     (a) The Parent has heretofore furnished to the Term Lenders its consolidated balance sheet and
statements of income, stockholders equity and cash flows (i) as of and for the fiscal year ended
December 31, 2007, reported on by Deloitte & Touche LLP, independent public accountants, and (ii)
as of and for the fiscal quarter and the portion of the fiscal year ended June 30, 2008, certified
by its chief financial officer. Such financial statements present fairly, in all material
respects, the financial position and results of operations and cash flows of the Parent and its
consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP,

42

 

subject to year-end audit adjustments and the absence of footnotes in the case of the
statements referred to in clause (ii) above.

     (b) Since December 31, 2007, there has not occurred any event or change that, individually or
in the aggregate, has had or could reasonably be expected to have a Material Adverse Effect.

     5.05 Properties.

     (a) Each of the Parent and its Subsidiaries has good title to, or valid leasehold interests
in, all its real and personal property material to its business, except for minor defects in title
that do not interfere with its ability to conduct its business as currently conducted or to utilize
such properties for their intended purposes and except where the failure to have such good title or
valid leasehold interests, individually or in the aggregate, would not reasonably be expected to
result in a Material Adverse Effect.

     (b) Each of the Parent and its Subsidiaries owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual property material to its business, and the
use thereof by the Parent and its Subsidiaries does not infringe upon the rights of any other
Person, except for any such infringements that, individually or in the aggregate, would not
reasonably be expected to result in a Material Adverse Effect.

     5.06 Litigation and Environmental Matters.

     (a) There are no actions, suits or proceedings (including investigative proceedings) by or
before any arbitrator or Governmental Authority pending against or, to the knowledge of the Parent
or the Borrower, threatened against or affecting the Parent or any Subsidiary, that would
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect
(other than the Disclosed Matters).

     (b) Except for the Disclosed Matters and except with respect to any other matters that,
individually or in the aggregate, would not reasonably be expected to result in a Material Adverse
Effect, neither the Parent nor any Subsidiary (i) has failed to comply with any Environmental Law
or to obtain, maintain or comply with any permit, license or other approval required under any
Environmental Law, (ii) has become subject to any Environmental Liability or (iii) has received
notice of any claim with respect to any Environmental Liability.

     5.07 Compliance with Laws; Absence of Default. Each of the Parent and its Subsidiaries is in
compliance with all Laws applicable to it or its property, except where the failure to do so,
individually or in the aggregate, would not reasonably be expected to result in a Material Adverse
Effect. No Default has occurred and is continuing.

     5.08 Investment Company Status. Neither the Parent nor any Subsidiary is an “investment
company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

     5.09 Taxes. Each of the Parent and its Subsidiaries has timely filed or caused to be filed
all Tax returns and reports required to have been filed and has paid or caused to be paid all

43

 

Taxes required to have been paid by it, except (a) Taxes that are being contested in good
faith by appropriate proceedings and for which the Parent or such Subsidiary, as applicable, has
set aside on its books adequate reserves or (b) to the extent that the failure to do so would not
reasonably be expected to result in a Material Adverse Effect.

     5.10 ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken
together with all other such ERISA Events for which liability is reasonably expected to occur,
would reasonably be expected to result in a Material Adverse Effect. The present value of all
accumulated benefit obligations under each Pension Plan (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent
financial statements reflecting such amounts, exceed the fair market value of the assets of such
Pension Plan, and the present value of all accumulated benefit obligations of all underfunded
Pension Plans (based on the assumptions used for purposes of Statement of Financial Accounting
Standards No. 87) did not, as of the date of the most recent financial statements reflecting such
amounts, exceed the fair market value of the assets of all such underfunded Pension Plans, in each
case, by an amount that has had, or would reasonably be expected to have, a Material Adverse
Effect.

     5.11 Disclosure. Neither the Marketing Information nor any of the other reports, financial
statements, certificates or other information furnished by or on behalf of the Parent or the
Borrower to the Administrative Agent or any Term Lender in connection with the negotiation of this
Agreement or delivered on or prior to the Closing Date hereunder (as modified or supplemented by
other information so furnished) contains any material misstatement of fact or omits to state any
material fact necessary to make the statements therein, in the light of the circumstances under
which they were made, not misleading; provided that, with respect to projected financial
information, the Parent and the Borrower represent only that such information was prepared in good
faith based upon assumptions believed to be reasonable at the time.

     5.12 Subsidiaries. Schedule 5.12 sets forth the name and jurisdiction of organization
of, and the direct or indirect ownership interest of the Parent in, each Subsidiary, and identifies
each Subsidiary that is a Guarantor, in each case as of the Closing Date.

     5.13 Solvency. Immediately after the consummation of the Transactions to occur on the Closing
Date, (a) the fair value of the assets of each Loan Party, at a fair valuation, will exceed its
debts and liabilities, subordinated, contingent or otherwise; (b) the present fair saleable value
of the property of each Loan Party will be greater than the amount that will be required to pay the
probable liability of its debts and other liabilities, subordinated, contingent or otherwise, as
such debts and other liabilities become absolute and matured; (c) each Loan Party will be able to
pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities
become absolute and matured; (d) each Loan Party will not have unreasonably small capital with
which to conduct the business in which it is engaged as such business is now conducted and is
proposed to be conducted following the Closing Date; (e) no Loan Party, by reason of actual or
anticipated financial difficulties, has commenced or intends to commence negotiations with one or
more of its creditors with a view to rescheduling any of its Indebtedness; and (f) no moratorium
has been declared and, in the opinion of the Parent and the Borrower, no moratorium is reasonably
likely to be declared in the foreseeable future, in each case, in respect of any Indebtedness of
any Loan Party.

44

 

     5.14 Use of Proceeds. No Loan Party is engaged, and none of them will engage, principally or
as one of its important activities, in the business of purchasing or carrying margin stock (within
the meaning of Regulation U issued by the FRB), or extending credit for the purpose of purchasing
or carrying margin stock.

     5.15 Pari Passu. The Obligations rank at least pari passu with all other unsecured
Indebtedness of the Loan Parties.

ARTICLE VI.

AFFIRMATIVE COVENANTS

     So long as any Term Lender shall have any Term Loan Commitment hereunder or any Term Loan or
other Obligation hereunder shall remain unpaid, the Parent and the Borrower covenant and agree with
the Term Lenders that:

     6.01 Financial Statements; Ratings Change and Other Information. The Parent will furnish to
the Administrative Agent and each Term Lender:

     (a) as soon as available and in any event within 120 days (or, if earlier, the date that is
fifteen (15) days after the reporting date for such information required by the SEC) after the end
of each fiscal year of the Parent, its audited consolidated balance sheet and related statements of
operations, stockholders’ equity and cash flows as of the end of and for such year, setting forth
in each case in comparative form the figures for the previous fiscal year, all reported on by
Deloitte & Touche LLP or other independent public accountants of recognized national standing
(without a “going concern” or like qualification or exception and without any material
qualification or exception as to the scope of such audit) to the effect that such consolidated
financial statements present fairly in all material respects the financial condition and results of
operations of the Parent and its consolidated Subsidiaries on a consolidated basis in accordance
with GAAP consistently applied;

     (b) as soon as available and in any event within 60 days (or, if earlier, the date that is

balance sheet and related statements of operations, stockholders’ equity and cash flows as of the
end of and for such fiscal quarter and the then elapsed portion of the fiscal year, setting forth
in each case in comparative form the figures for the corresponding period or periods of (or, in the
case of the balance sheet, as of the end of) the previous fiscal year, all certified by a Financial
Officer of the Parent as presenting fairly in all material respects the financial condition and
results of operations of the Parent and its consolidated Subsidiaries on a consolidated basis in

anew or continues to exist at such time, in which case it shall be included on such Compliance
Certificate) has occurred and, if such Default has occurred or exists, specifying the

45

 

details thereof and any action taken or proposed to be taken with respect thereto, (ii)
setting forth reasonably detailed calculations of the financial covenants set forth in, and
demonstrating compliance with, Sections 7.08(a) and (b), (iii) stating whether any

each such Material Acquisition, and a reasonably detailed explanation of the calculation of such
changes and (iv) stating whether any change in GAAP or in the application thereof that has not been
disclosed in any prior Compliance Certificate has occurred since the date of the audited financial

the financial covenants set forth in Sections 7.08(a) and (b) and, if any such
change has occurred, specifying the effect of such change on the financial statements accompanying
such certificate; provided that for the fiscal quarter of the Parent ended September 30,
2008, because such period ended prior to the Closing Date, the delivery under this Section
6.01(c) shall not require the certifications set forth in subparts (i) and (ii) above, but

fiscal quarter substantially in the form set forth as an attachment to the form of Compliance
Certificate;

     (d) concurrently with any delivery of financial statements under clause (a) above, a report

the case may be;

     (f) promptly after S&P or Moody’s shall have announced a change in the Debt Rating, written

     (h) promptly following any request therefor, such other information regarding the operations,
business affairs and financial condition of the Parent or any Subsidiary, or compliance with the
terms of this Agreement, as the Administrative Agent or any Term Lender may reasonably request.

     Documents required to be delivered pursuant to Section 6.01(a), (b) or
(e) (to the extent any such documents are included in materials otherwise filed with the
SEC) may be delivered

46

 

electronically and if so delivered, shall be deemed to have been delivered on the date (i) on
which the Parent or the Borrower posts such documents, or provides a link thereto on the Parent’s
or the Borrower’s website on the Internet at the website address listed on Schedule 10.02;
or (ii) on which such documents are posted on the Parent’s or the Borrower’s behalf on an Internet
or intranet website, if any, to which each Term Lender and the Administrative Agent have access
(whether a commercial, third-party website or whether sponsored by the Administrative Agent);
provided that: (i) the Parent or the Borrower, as applicable, shall deliver paper copies of
such documents to the Administrative Agent or any Term Lender upon the written request of such
Person and until a written request to cease delivering paper copies is given by such Person and
(ii) the Parent or the Borrower, as applicable, shall notify the Administrative Agent and each Term
Lender (by telecopier or electronic mail) of the posting of any such documents and provide to the
Administrative Agent by electronic mail electronic versions (i.e., soft copies) of such documents.
Notwithstanding anything contained herein, in every instance the Parent and the Borrower shall be
required to provide paper copies of the Compliance Certificates required by Section 6.01(c)
to the Administrative Agent. Except for such Compliance Certificates, the Administrative Agent
shall have no obligation to request the delivery or to maintain copies of the documents referred to
above, and in any event shall have no responsibility to monitor compliance by the Parent or the
Borrower with any such request for delivery, and each Term Lender shall be solely responsible for
requesting delivery to it or maintaining its copies of such documents.

     Each of the Parent and the Borrower hereby acknowledges that (a) the Administrative Agent
and/or one or more of the Book Managers will make available to the Term Lenders materials and/or
information provided by or on behalf of the Parent or the Borrower, as applicable, hereunder
(collectively, “Parent and Borrower Materials”) by posting the Parent and Borrower
Materials on IntraLinks or another similar electronic system (the “Platform”) and (b)
certain of the Term Lenders (each, a “Public Lender”) may have personnel who do not wish to
receive material non-public information with respect to the Parent, the Borrower or their
respective Affiliates, or the respective securities of any of the foregoing, and who may be engaged
in investment and other market-related activities with respect to such Persons’ securities. Each
of the Parent and the Borrower hereby agrees that (w) all Parent and Borrower Materials that are to
be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a
minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x)
by marking Parent and Borrower Materials “PUBLIC,” the Parent and the Borrower shall be deemed to
have authorized the Administrative Agent, the Book Managers and the Term Lenders to treat such
Parent and Borrower Materials as not containing any material non-public information with respect to
the Parent, the Borrower or their respective securities for purposes of United States Federal and
state securities laws (provided that to the extent such Parent and Borrower Materials constitute
Information, they shall be treated as set forth in Section 10.07); (y) all Parent and
Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the
Platform designated “Public Side Information”; and (z) the Administrative Agent and the Book
Managers shall be entitled to treat any Parent and Borrower Materials that are not marked “PUBLIC”
as being suitable only for posting on a portion of the Platform not designated “Public Side
Information”. Notwithstanding the foregoing, the Borrower shall not be under any obligation to
mark any Borrower Materials “PUBLIC.”

47

 

     6.02 Notices of Material Events. The Parent or the Borrower will furnish to the
Administrative Agent and each Term Lender prompt written notice of the following:

     (a) the occurrence of any Default;

     (b) the filing or commencement of any action, suit or proceeding by or before any arbitrator
or Governmental Authority against or affecting the Borrower or any Affiliate thereof that would
reasonably be expected to result in a Material Adverse Effect;

     (c) the occurrence of any ERISA Event that, alone or together with any other ERISA Events that
have occurred, would reasonably be expected to result in a Material Adverse Effect; and

     (d) any other development that results in, or could reasonably be expected to result in, a
Material Adverse Effect.

Each notice delivered under this Section shall be accompanied by a statement of a Financial Officer
or other Responsible Officer of the Parent or the Borrower setting forth the details of the event
or development requiring such notice and any action taken or proposed to be taken with respect
thereto.

     6.03 Existence; Conduct of Business.

     (a) The Parent and the Borrower will, and will cause each of the other Loan Parties to, do or
cause to be done all things necessary to preserve, renew and keep in full force and effect its
legal existence and the rights, licenses, permits, privileges and franchises material to the
conduct of its business; provided that the foregoing shall not prohibit any merger,
consolidation, liquidation or dissolution permitted under Section 7.04.

     (b) The Parent and the Borrower will, and will cause each of the other Subsidiaries to,
continue to engage (including after giving effect to any acquisition) only in a business of the
type that does not represent a fundamental change in the character of the business of the Parent
and its Subsidiaries, taken as a whole, conducted by the Parent and its Subsidiaries on the date of
execution of this Agreement, and businesses reasonably related thereto.

     6.04 Payment of Taxes. The Parent and the Borrower will, and will cause each of the other
Subsidiaries to, pay its Tax liabilities before the same shall become delinquent or in default,
except where (a) the validity or amount thereof is being contested in good faith by appropriate
proceedings and for which the Parent or such Subsidiary has set aside on its books adequate
reserves with respect thereto in accordance with GAAP or (b) the failure to make payment would not
reasonably be expected to result in a Material Adverse Effect.

     6.05 Maintenance of Properties; Insurance. The Parent and the Borrower will, and will cause
each of the other Subsidiaries to, (a) keep and maintain all property material to the conduct of
its business in good working order and condition, ordinary wear and tear excepted, and (b) maintain

48

 

Borrower) are financially sound and responsible at the time the relevant coverage is placed or

any representatives designated by the Administrative Agent or any Term Lender, upon reasonable
prior notice, to visit and inspect its properties, to examine and make extracts from its books and
records, and to discuss its affairs, finances and condition with its officers and independent
accountants, all at such reasonable times and as often as reasonably requested.

     6.07 Compliance with Laws. The Parent and the Borrower will, and will cause each of the other
Subsidiaries to, comply with all Laws, rules, regulations and orders of any Governmental Authority
applicable to it or its property, except where the failure to do so, individually or in the
aggregate, would not reasonably be expected to result in a Material Adverse Effect.

     6.08 Use of Proceeds. The proceeds of the Term Loans will be used, along with certain other
funds of the Parent and its Subsidiaries, (a) to pay the holders of the Equity Interests of the
Acquired Company a portion of the cash consideration for their shares of the Acquired Company in
connection with the Merger, (b) to pay fees and expenses of the Transactions, (c) to refinance the

Subsidiaries to ensure, that no part of the proceeds of any Term Loan will be used, whether
directly or indirectly, and whether immediately, incidentally or ultimately, to purchase or carry
margin stock (within the meaning of Regulation U of the FRB) or to extend credit to others for the
purpose of purchasing or carrying margin stock or to refund indebtedness originally incurred for
such purpose.

purposes of the Loan Documents. Notwithstanding anything to the contrary herein, the Parent will
not engage, and will not permit the Borrower to engage, in any transaction that would reduce the
percentage of Equity Interests owned by the Parent in the Borrower, except for (x) sales, transfers

otherwise disposed in reliance upon this clause (d) shall not exceed $1,100,000,000 during any
fiscal year and shall not exceed $2,750,000,000 during the period from and including June 30, 2008
to but excluding the Maturity Date; provided further that in the event, and on each
occasion, that any Material Acquisition is consummated after the Closing Date, each of the two
amounts set forth in the immediately preceding proviso shall be increased by an amount equal to 25%
of the value of the assets acquired pursuant to such Material Acquisition (valued based upon the
amount at which such assets would be reflected on a balance sheet of the Parent and its
Subsidiaries prepared on a consolidated basis in accordance with GAAP after giving effect to such
Material Acquisition);

provided that all Dispositions permitted hereby (other than those permitted by clause (a)
or (b) above) shall be made for full fair value and on an arm’s length basis, as reasonably
determined in good faith by the Parent or the Borrower, taking into account all relevant
considerations. Any merger or consolidation of a Subsidiary with or into any other Person that
results in such Subsidiary ceasing to be a Subsidiary or the Parent owning a reduced percentage of
the Equity Interests in such Subsidiary shall, in each case, be treated as a Disposition of such
Subsidiary (or the relevant portion thereof) for purposes of this Section 7.05.

Subsidiary to, declare or make, directly or indirectly, any Restricted Payment, or incur any

availability under the revolving credit facilities of the Five-Year Credit Facilities is at least
$100,000,000 (such permitted purchases, the “Permitted Parent Equity Repurchases”);

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

58

 

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

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

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

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

     The Administrative Agent shall not be liable for any action taken or not taken by it (i) with
the consent or at the request of the Required Lenders (or such other number or percentage of the
Term Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith
shall be necessary, under the circumstances as provided in Sections 10.01 and 8.02)
or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent
shall be deemed not to have knowledge of any Default unless and until notice describing such
Default is given to the Administrative Agent by the Borrower or a Term Lender.

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

     9.04 Reliance by Administrative Agent.

     The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument, document or other
writing (including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or otherwise

59

 

authenticated by the proper Person. The Administrative Agent also may rely upon any statement
made to it orally or by telephone and believed by it to have been made by the proper Person, and
shall not incur any liability for relying thereon. In determining compliance with any condition
hereunder to the making of a Term Loan that by its terms must be fulfilled to the satisfaction of a
Term Lender, the Administrative Agent may presume that such condition is satisfactory to such Term
Lender unless the Administrative Agent shall have received notice to the contrary from such Term
Lender prior to the making of such Term Loan. The Administrative Agent may consult with legal
counsel (who may be counsel for the Borrower or the Parent), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts.

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

     9.06 Resignation of Administrative Agent. The Administrative Agent may at any time give
notice of its resignation to the Term Lenders and the Borrower. Upon receipt of any such notice of
resignation, the Required Lenders shall have the right, in consultation with the Borrower, to
appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of
any such bank with an office in the United States. If no such successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment within 30 days after the
retiring Administrative Agent gives notice of its resignation, then the retiring Administrative
Agent may, on behalf of the Term Lenders, appoint, in consultation with the Borrower, a successor
Administrative Agent meeting the qualifications set forth above; provided that if the
Administrative Agent shall notify the Borrower and the Term Lenders that no qualifying Person has
accepted such appointment, then such resignation shall nonetheless become effective in accordance
with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder and under the other Loan Documents and (2) all payments, communications and
determinations provided to be made by, to or through the Administrative Agent shall instead be made
by or to each Term Lender directly, until such time as the Required Lenders appoint a successor
Administrative Agent as provided for above in this Section. Upon the acceptance of a successor’s
appointment as Administrative Agent hereunder, such successor shall succeed to and become vested
with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative
Agent, and the retiring Administrative Agent shall be discharged from all of its duties and
obligations hereunder or under the other Loan Documents (if not already discharged therefrom as
provided above in this Section). The fees payable by the Borrower to a successor Administrative
Agent shall be the same as those payable to its predecessor unless otherwise agreed between the
Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and
under the other Loan Documents, the provisions of this Article and Section 10.04 shall
continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their
respective Related Parties in respect of

60

 

any actions taken or omitted to be taken by any of them while the retiring Administrative
Agent was acting as Administrative Agent.

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

     9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the Lead
Arranger, the Book Managers, the Syndication Agents or the Documentation Agents listed on the cover
page hereof shall have any powers, duties or responsibilities under this Agreement or any of the
other Loan Documents, except in its capacity, as applicable, as the Administrative Agent or a Term
Lender hereunder or, with respect to the Book Managers, as expressly provided herein.

     9.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding
under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the
Administrative Agent (irrespective of whether the principal of any Term Loan shall then be due and
payable as herein expressed or by declaration or otherwise and irrespective of whether the
Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered,
by intervention in such proceeding or otherwise

     (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Term Loans and all other Obligations that are owing and unpaid and to file
such other documents as may be necessary or advisable in order to have the claims of the Term
Lenders and the Administrative Agent (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Term Lenders and the Administrative Agent and their
respective agents and counsel and all other amounts due the Term Lenders and the Administrative
Agent under Sections 2.08 and 10.04) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Term Lender to make such payments to
the Administrative Agent and, in the event that the Administrative Agent shall consent to the
making of such payments directly to the Term Lenders, to pay to the Administrative Agent any amount
due for the reasonable compensation, expenses, disbursements and advances of the Administrative
Agent and its agents and counsel, and any other amounts due the Administrative Agent under
Sections 2.08 and 10.04.

61

 

     Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Term Lender any plan of reorganization, arrangement,
adjustment or composition affecting the Obligations or the rights of any Term Lender to authorize
the Administrative Agent to vote in respect of the claim of any Term Lender in any such proceeding.

     9.10 Guaranty Matters. The Term Lenders irrevocably authorize the Administrative Agent, at
its option and in its discretion, to release any Guarantor from its obligations under the Guaranty
Agreement if such Person ceases to be a Subsidiary of the Parent as a result of a transaction
permitted hereunder. Upon request by the Administrative Agent at any time, the Required Lenders
will confirm in writing the Administrative Agent’s authority to release any Guarantor from its
obligations under the Guaranty Agreement pursuant to this Section 9.10.

ARTICLE X.

MISCELLANEOUS

     10.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other
Loan Document, and no consent to any departure by the Borrower or any other Loan Party therefrom,
shall be effective unless in writing signed by the Required Lenders (or the Administrative Agent
with the consent of the Required Lenders) and the Borrower or the applicable Loan Party, as the
case may be, and acknowledged by the Administrative Agent, and each such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which given;
provided that no such amendment, waiver or consent shall:

     (a) waive any condition set forth in Section 4.01 (other than Section
4.01(i)(i) or (j), which may be waived solely by the Person to whom any such amounts
are due) without the written consent of each Term Lender;

     (b) extend or increase the Term Loan Commitment of any Term Lender (or reinstate any Term Loan
Commitment terminated as a result of funding the Term Loans on the Closing Date or pursuant to
Section 8.02) without the written consent of such Term Lender;

     (c) postpone any date fixed by this Agreement or any other Loan Document for any payment
(including mandatory prepayments) of principal, interest, fees or other amounts due to the Term
Lenders (or any of them) hereunder or under any other Loan Document without the written consent of
each Term Lender directly affected thereby;

     (d) reduce the principal of, or the rate of interest specified herein on, any Term Loan, or
(subject to clause (ii) of the second proviso to this Section 10.01) any fees or other
amounts payable hereunder or under any other Loan Document without the written consent of each Term
Lender directly affected thereby; provided that only the consent of the Required Lenders
shall be necessary (i) to amend the definition of “Default Rate” or to waive any obligation of the
Borrower to pay interest at the Default Rate or (ii) to amend any financial covenant hereunder (or
any defined term used therein) even if the effect of such amendment would be to reduce the rate of
interest on any Term Loan or to reduce any fee payable hereunder;

62

 

     (e) change Section 2.10 or Section 8.03 in a manner that would alter the pro
rata sharing of payments required thereby without the written consent of each Term Lender;

     (f) change any provision of this Section 10.01 or the definition of “Required Lenders”
or any other provision hereof specifying the number or percentage of Term Lenders required to
amend, waive or otherwise modify any rights hereunder or make any determination or grant any
consent hereunder without the written consent of each Term Lender; or

     (g) release all or substantially all of the value of the Guaranty Agreement without the
written consent of each Term Lender, except to the extent the release of any Guarantor is permitted
pursuant to Section 9.10 (in which case such release may be made by the Administrative
Agent acting alone);

and provided, further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Term Lenders required above,
affect the rights or duties of the Administrative Agent under this Agreement or any other Loan
Document; and (ii) each Fee Letter may be amended, or rights or privileges thereunder waived, in a
writing executed only by the parties thereto. Notwithstanding anything to the contrary herein, no
Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent
hereunder, except that the Term Loan Commitment of such Term Lender may not be increased or
extended without the consent of such Term Lender.

     If any Term Lender does not consent to a proposed amendment, waiver, consent or release with
respect to any Loan Document that requires the consent of each Term Lender or such Term Lender and
that has been approved by the Required Lenders, the Borrower may replace such non-consenting Term
Lender in accordance with Section 10.13; provided that such amendment, waiver,
consent or release can be effected as a result of the assignment contemplated by such Section
(together with all other such assignments required by the Borrower to be made pursuant to this
paragraph).

     10.02 Notices; Effectiveness; Electronic Communications.

     (a) Notices Generally. Except in the case of notices and other communications
expressly permitted to be given by telephone (and except as provided in subsection (b) below), all
notices and other communications provided for herein shall be in writing and shall be delivered by
hand or overnight courier service, mailed by certified or registered mail or sent by telecopier or
(subject to subsection (b) below) email as follows, and all notices and other communications
expressly permitted hereunder to be given by telephone shall be made to the applicable telephone

63

 

Notices and other communications sent by hand or overnight courier service, or mailed by certified
or registered mail, shall be deemed to have been given when received; notices and other
communications sent by telecopier shall be deemed to have been given when sent (except that, if not
given during normal business hours for the recipient, shall be deemed to have been given at the
opening of business on the next business day for the recipient). Notices and other communications
delivered through electronic communications to the extent provided in subsection (b) below, shall
be effective as provided in such subsection (b).

     (b) Electronic Communications. Notices and other communications to the Term Lenders
hereunder may be delivered or furnished by electronic communication (including e-mail and Internet
or intranet websites) pursuant to procedures approved by the Administrative Agent; provided
that the foregoing shall not apply to notices to any Term Lender pursuant to Article II, if
such Term Lender has notified the Administrative Agent that it is incapable of receiving notices
under such Article by electronic communication. The Administrative Agent or the Borrower may, in
its discretion, agree to accept notices and other communications to it hereunder by electronic
communications pursuant to procedures approved by it; provided that approval of such
procedures may be limited to particular notices or communications.

     Unless the Administrative Agent otherwise prescribes, (i) notices and other communications
sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement
from the intended recipient (such as by the “return receipt requested” function, as available,
return e-mail or other written acknowledgement); provided that, if such notice or other
communication is not sent during the normal business hours of the recipient, such notice or
communication shall be deemed to have been sent at the opening of business on the next business day
for the recipient, and (ii) notices or communications posted to an Internet or intranet website
shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as
described in the foregoing clause (i) of notification that such notice or communication is
available and identifying the website address therefor.

     (c) The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT
PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE PARENT AND BORROWER
MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR
OMISSIONS FROM THE PARENT AND BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR
STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY
ANY AGENT PARTY IN CONNECTION WITH THE PARENT AND BORROWER MATERIALS OR THE PLATFORM. In no event
shall the Administrative Agent or any of its Related Parties (collectively, the “Agent
Parties”) have any liability to the Parent, the Borrower, any Term Lender or any other Person
for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or
otherwise) arising out of the Parent’s, the Borrower’s or the Administrative Agent’s transmission
of Parent and Borrower Materials through the Internet, except to the extent that such losses,
claims, damages, liabilities or expenses are determined by a court of competent jurisdiction by a
final and nonappealable judgment to have resulted from the gross negligence or willful misconduct
of such Agent Party; provided that in no event shall any Agent Party have any liability to
the Parent, the Borrower,

64

 

any Term Lender or any other Person for indirect, special, incidental, consequential or
punitive damages (as opposed to direct or actual damages).

     (d) Change of Address, Etc. Each of the Parent, the Borrower and the Administrative
Agent may change its address, telecopier, e-mail or telephone number for notices and other
communications hereunder by notice to the other parties hereto. Each other Term Lender may change
its address, telecopier, e-mail or telephone number for notices and other communications hereunder
by notice to the Borrower and the Administrative Agent. In addition, each Term Lender agrees to
notify the Administrative Agent from time to time to ensure that the Administrative Agent has on
record (i) an effective address, contact name, telephone number, telecopier number and e-mail
address to which notices and other communications may be sent and (ii) accurate wire instructions
for such Term Lender. Furthermore, each Public Lender agrees to cause at least one individual at
or on behalf of such Public Lender to at all times have selected the “Private Side Information” or
similar designation on the content declaration screen of the Platform in order to enable such
Public Lender or its delegate, in accordance with such Public Lender’s compliance procedures and
applicable Law, including United States Federal and state securities Laws, to make reference to
Parent and Borrower Materials that are not made available through the “Public Side Information”
portion of the Platform and that may contain material non-public information with respect to the
Parent or the Borrower or their respective securities for purposes of United States Federal or
state securities laws.

     (e) Reliance by Administrative Agent and Term Lenders. The Administrative Agent and
the Term Lenders shall be entitled to rely and act upon any notices (including telephonic Term Loan
Notices) purportedly given by or on behalf of the Parent or the Borrower even if (i) such notices
were not made in a manner specified herein, were incomplete or were not preceded or followed by any
other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient,
varied from any confirmation thereof. The Parent and the Borrower shall each indemnify the
Administrative Agent, each Term Lender and the Related Parties of each of them from all losses,
costs, expenses and liabilities resulting from the reliance by such Person on each notice
purportedly given by or on behalf of the Parent or the Borrower. All telephonic notices to and
other telephonic communications with the Administrative Agent may be recorded by the Administrative
Agent, and each of the parties hereto hereby consents to such recording.

     10.03 No Waiver; Cumulative Remedies; Enforcement. No failure by any Term Lender or the
Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy,
power or privilege hereunder or under any Loan Document shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude
any other or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges herein provided, and provided under each
other Loan Document, are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

     Notwithstanding anything to the contrary contained herein or in any other Loan Document, the
authority to enforce rights and remedies hereunder and under the other Loan Documents against the
Loan Parties or any of them shall be vested exclusively in, and all actions and proceedings at law
in connection with such enforcement shall be instituted and maintained exclusively by, the
Administrative Agent in accordance with Section 8.02 for the benefit of all

65

 

the Term Lenders; provided that the foregoing shall not prohibit (a) the
Administrative Agent from exercising on its own behalf the rights and remedies that inure to its
benefit (solely in its capacity as Administrative Agent) hereunder and under the other Loan
Documents, (b) any Term Lender from exercising setoff rights in accordance with Section
10.08 (subject to the terms of Section 2.10), or (c) any Term Lender from filing proofs
of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding
relative to any Loan Party under any Debtor Relief Law; and provided, further, that
if at any time there is no Person acting as Administrative Agent hereunder and under the other Loan
Documents, then (i) the Required Lenders shall have the rights otherwise ascribed to the
Administrative Agent pursuant to Section 8.02 and (ii) in addition to the matters set forth
in clauses (b), (c) and (d) of the preceding proviso and subject to Section 2.10, any Term
Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to
it and as authorized by the Required Lenders.

     10.04 Expenses; Indemnity; Damage Waiver.

     (a) Costs and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket
expenses incurred by the Administrative Agent and its Affiliates (including the reasonable fees,
charges and disbursements of counsel for the Administrative Agent), in connection with the
syndication of the credit facilities provided for herein, the preparation, negotiation, execution,
delivery and administration of this Agreement and the other Loan Documents or any amendments,
modifications or waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), and (ii) all out-of-pocket expenses incurred
by the Administrative Agent or any Term Lender (including the fees, charges and disbursements of
any counsel for the Administrative Agent or any Term Lender), in connection with the enforcement or
protection of its rights (A) in connection with this Agreement and the other Loan Documents,
including its rights under this Section, or (B) in connection with the Term Loans made hereunder,
including all such out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Term Loans.

     (b) Indemnification by the Borrower. Each of the Parent and the Borrower shall
indemnify the Administrative Agent (and any sub-agent thereof) and each Term Lender, and each
Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, (including the fees, charges and disbursements of any
counsel for any Indemnitee) (excluding Taxes which shall be governed by Section 3.01),
incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower
or any other Loan Party arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated
hereby or thereby, the performance by the parties hereto of their respective obligations hereunder
or thereunder, the consummation of the transactions contemplated hereby or thereby, or, in the case
of the Administrative Agent (and any sub-agent thereof) and its Related Parties only, the
administration of this Agreement and the other Loan Documents, (ii) any Term Loan or the use or
proposed use of the proceeds therefrom, (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property owned or operated by the Parent or any of its
Subsidiaries, or any Environmental Liability related in any way to the Parent or any of its
Subsidiaries, or (iv) any actual or prospective claim, litigation,

66

 

investigation or proceeding relating to any of the foregoing, whether based on contract, tort
or any other theory, whether brought by a third party or by the Borrower or any other Loan Party or
any of the Borrower’s or such Loan Party’s directors, shareholders or creditors, and regardless of
whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y)
result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for
breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if
the Borrower or such other Loan Party has obtained a final and nonappealable judgment in its favor
on such claim as determined by a court of competent jurisdiction.

     (c) Reimbursement by Term Lenders. To the extent that the Parent and the Borrower for
any reason fail to indefeasibly pay any amount required under subsection (a) or (b) of this Section
to be paid by it to the Administrative Agent (or any sub-agent thereof) or any Related Party of any
of the foregoing, each Term Lender severally agrees to pay to the Administrative Agent (or any such
sub-agent) or such Related Party, as the case may be, such Term Lender’s Applicable Percentage
(determined as of the time that the applicable unreimbursed expense or indemnity payment is sought)
of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim,
damage, liability or related expense, as the case may be, was incurred by or asserted against the
Administrative Agent (or any such sub-agent) in its capacity as such, or against any Related Party
of any of the foregoing acting for the Administrative Agent (or any such sub-agent) in connection
with such capacity. The obligations of the Term Lenders under this subsection (c) are subject to
the provisions of Section 2.09(d).

     (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, neither the Parent, the Borrower, the Administrative Agent nor any Term Lender
shall assert, and each of them hereby waives, any claim against any Person party to this Agreement
or against any Indemnitee, on any theory of liability, for special, indirect, consequential or
punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as
a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated
hereby, the transactions contemplated hereby or thereby, any Term Loan or the use of the proceeds
thereof. No Indemnitee referred to in subsection (b) above shall be liable for any damages arising
from the use by unintended recipients of any information or other materials distributed to such
unintended recipients by such Indemnitee through telecommunications, electronic or other
information transmission systems in connection with this Agreement or the other Loan Documents or
the transactions contemplated hereby or thereby other than for direct or actual damages resulting
from the gross negligence or willful misconduct of such Indemnitee as determined by a final and
nonappealable judgment of a court of competent jurisdiction.

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

     (f) Survival. The agreements in this Section shall survive the resignation of the
Administrative Agent, the replacement of any Term Lender, the termination of the Term Loan
Commitments and the repayment, satisfaction or discharge of all the other Obligations.

67

 

     10.05 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is
made to the Administrative Agent or any Term Lender, or the Administrative Agent or any Term Lender
exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof
is subsequently invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent or such Term Lender
in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any
proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the
obligation or part thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such setoff had not occurred, and (b)
each Term Lender severally agrees to pay to the Administrative Agent upon demand its applicable
share (without duplication) of any amount so recovered from or repaid by the Administrative Agent,
plus interest thereon from the date of such demand to the date such payment is made at a
rate per annum equal to the applicable Overnight Rate from time to time in effect. The obligations
of the Term Lenders under clause (b) of the preceding sentence shall survive the payment in full of
the Obligations and the termination of this Agreement.

     10.06 Successors and Assigns.

     (a) Successors and Assigns Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that neither (x) the Borrower nor the Parent may assign or
otherwise transfer any of its rights or obligations hereunder without the prior written consent of
the Administrative Agent and each Term Lender; provided that a merger or consolidation that
complies with Section 7.04 shall not be construed as an assignment or transfer for purposes of this
clause (x) and (y) no Term Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this
Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this
Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions
of subsection (f) of this Section (and any other attempted assignment or transfer by any party
hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section
and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative
Agent and the Term Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

     (b) Assignments by Term Lenders. Any Term Lender may at any time assign to one or
more assignees all or a portion of its rights and obligations under this Agreement (including all
or a portion of its Term Loans at the time owing to it); provided that any such assignment
shall be subject to the following conditions:

     (i) Minimum Amounts.

     (A) in the case of an assignment of the entire remaining amount of the
assigning Term Lender’s Term Loans at the time owing to it under the Term Loan
Facility, or in the case of an assignment to a Term Lender, an Affiliate of a Term
Lender or an Approved Fund, no minimum amount need be assigned; and

68

 

     (B) in any case not described in subsection (b)(i)(A) of this Section, the
aggregate principal outstanding balance of the Term Loans of the assigning Term
Lender subject to each such assignment, determined as of the date the Assignment and
Assumption with respect to such assignment is delivered to the Administrative Agent
or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade
Date, shall not be less than $5,000,000, unless each of the Administrative Agent
and, so long as no Event of Default has occurred and is continuing, the Borrower
otherwise consents (each such consent not to be unreasonably withheld or delayed);
provided that concurrent assignments to members of an Assignee Group and
concurrent assignments from members of an Assignee Group to a single Eligible
Assignee (or to an Eligible Assignee and members of its Assignee Group) will be
treated as a single assignment for purposes of determining whether such minimum
amount has been met.

     (ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Term Lender’s rights and obligations
under this Agreement with respect to the Term Loans assigned;

     (iii) Required Consents. No consent shall be required for any assignment
except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

     (A) the consent of the Borrower (such consent not to be unreasonably withheld
or delayed; provided that the Borrower will be deemed to have consented to such
assignment if its response is not received by the Administrative Agent within five
days of its receipt of notice of such assignment) shall be required unless (1) an
Event of Default has occurred and is continuing at the time of such assignment or
(2) such assignment is to a Term Lender, an Affiliate of a Term Lender or an
Approved Fund; and

     (B) the consent of the Administrative Agent (such consent not to be
unreasonably withheld or delayed) shall be required for assignments in respect of
any Term Loan to a Person that is not a Term Lender, an Affiliate of a Term Lender
or an Approved Fund.

     (iv) Assignment and Assumption. The parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee in the amount of $3,500; provided that the
Administrative Agent may, in its sole discretion, elect to waive such processing and
recordation fee in the case of any assignment. The assignee, if it is not a Term Lender,
shall deliver to the Administrative Agent an Administrative Questionnaire.

     (v) No Assignment to Borrower. No such assignment shall be made to the Parent,
the Borrower or any of the Parent’s or Borrower’s Affiliates or Subsidiaries.

     (vi) No Assignment to Natural Persons. No such assignment shall be made to a
natural person.

69

 

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c)
of this Section, from and after the effective date specified in each Assignment and Assumption, the
assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Term Lender under this
Agreement, and the assigning Term Lender thereunder shall, to the extent of the interest assigned
by such Assignment and Assumption, be released from its obligations under this Agreement (and, in
the case of an Assignment and Assumption covering all of the assigning Term Lender’s rights and
obligations under this Agreement, such Term Lender shall cease to be a party hereto) but shall
continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and
10.04 with respect to facts and circumstances occurring prior to the effective date of such
assignment. Upon request, the Borrower (at its expense) shall execute and deliver a Term Loan Note
to the assignee Term Lender. Any assignment or transfer by a Term Lender of rights or obligations
under this Agreement that does not comply with this subsection shall be treated for purposes of
this Agreement as a sale by such Term Lender of a participation in such rights and obligations in
accordance with subsection (d) of this Section.

     (c) Register. The Administrative Agent, acting solely for this purpose as an agent of
the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and
Assumption delivered to it and a register for the recordation of the names and addresses of the
Term Lenders, and the Term Loan Commitments of, and principal amounts of the Term Loans owing to,
each Term Lender pursuant to the terms hereof from time to time (the “Register”). The
entries in the Register shall be conclusive, and the Parent, the Borrower, the Administrative Agent
and the Term Lenders may treat each Person whose name is recorded in the Register pursuant to the
terms hereof as a Term Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register shall be available for inspection by the Parent, the Borrower and
any Term Lender, at any reasonable time and from time to time upon reasonable prior notice.

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

     Any agreement or instrument pursuant to which a Term Lender sells such a participation shall
provide that such Term Lender shall retain the sole right to enforce this Agreement and to approve
any amendment, modification or waiver of any provision of this Agreement; provided that
such agreement or instrument may provide that such Term Lender will not, without the consent of the
Participant, agree to any amendment, waiver or other modification described in the first proviso to
Section 10.01 that affects such Participant. Subject to subsection (e) of this Section,
each Borrower agrees that each Participant shall be entitled to the benefits of Sections
3.01, 3.04 and 3.05 to the same extent as if it were a Term Lender and had
acquired its interest

70

 

by assignment pursuant to subsection (b) of this Section. To the extent permitted by law,
each Participant also shall be entitled to the benefits of Section 10.08 as though it were
a Term Lender; provided such Participant agrees to be subject to Section 2.10 as
though it were a Term Lender.

     (e) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Section 3.01 or 3.04 than the applicable Term
Lender would have been entitled to receive with respect to the participation sold to such
Participant, unless the sale of the participation to such Participant is made with the Borrower’s
prior written consent. A Participant that would be a Foreign Lender if it were a Term Lender shall
not be entitled to the benefits of Section 3.01, unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 3.01(e) as though it were a Term Lender.

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

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

     For purposes of this Section, “Information” means all information received from the
Parent, the Borrower or any Subsidiary relating to the Parent or any Subsidiary or any of their
respective businesses, other than any such information that is available to the Administrative
Agent or any Term Lender on a nonconfidential basis prior to disclosure by the Parent, the

71

 

Borrower or any Subsidiary; provided that, in the case of information received from
the Parent, the Borrower or any Subsidiary after the date hereof, such information is clearly
identified at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own confidential
information.

     Each of the Administrative Agent and the Term Lenders acknowledges that (a) the Information
may include material non-public information concerning the Parent, the Borrower or a Subsidiary, as
the case may be, (b) it has developed compliance procedures regarding the use of material
non-public information and (c) it will handle such material non-public information in accordance
with applicable Law, including United States Federal and state securities Laws.

     10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each
Term Lender and each of their respective Affiliates is hereby authorized at any time and from time
to time, to the fullest extent permitted by applicable law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final, in whatever currency) at any
time held and other obligations (in whatever currency) at any time owing by such Term Lender or any
such Affiliate to or for the credit or the account of the Borrower or any other Loan Party against
any and all of the obligations of the Borrower or such Loan Party now or hereafter existing under
this Agreement or any other Loan Document to such Term Lender, irrespective of whether or not such
Term Lender shall have made any demand under this Agreement or any other Loan Document and although
such obligations of the Borrower or such Loan Party may be contingent or unmatured or are owed to a
branch or office of such Term Lender different from the branch or office holding such deposit or
obligated on such indebtedness. The rights of each Term Lender and their respective Affiliates
under this Section are in addition to other rights and remedies (including other rights of setoff)
that such Term Lender or their respective Affiliates may have. Each Term Lender agrees to notify
the Borrower and the Administrative Agent promptly after any such setoff and application;
provided that the failure to give such notice shall not affect the validity of such setoff
and application.

     10.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any
Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the
maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If
the Administrative Agent or any Term Lender shall receive interest in an amount that exceeds the
Maximum Rate, the excess interest shall be applied to the principal of the Term Loans or, if it
exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest
contracted for, charged, or received by the Administrative Agent or a Term Lender exceeds the
Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any
payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude
voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in
equal or unequal parts the total amount of interest throughout the contemplated term of the
Obligations hereunder.

     10.10 Counterparts; Integration; Effectiveness. This Agreement may be executed in
counterparts (and by different parties hereto in different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract.

72

 

This Agreement and the other Loan Documents constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except as provided in
Section 4.01, this Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received counterparts hereof
that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy or other electronic imaging
means shall be effective as delivery of a manually executed counterpart of this Agreement.

     10.11 Survival of Representations and Warranties. All representations and warranties made
hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or
in connection herewith or therewith shall survive the execution and delivery hereof and thereof.
Such representations and warranties have been or will be relied upon by the Administrative Agent
and each Term Lender, regardless of any investigation made by the Administrative Agent or any Term
Lender or on their behalf and notwithstanding that the Administrative Agent or any Term Lender may
have had notice or knowledge of any Default at the time of the Term Loan Borrowing, and shall
continue in full force and effect as long as any Term Loan or any other Obligation hereunder shall
remain unpaid or unsatisfied.

     10.12 Severability. If any provision of this Agreement or the other Loan Documents is held to
be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the
remaining provisions of this Agreement and the other Loan Documents shall not be affected or
impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the illegal, invalid or unenforceable provisions. The
invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction.

     10.13 Replacement of Term Lenders. If any Term Lender requests compensation under Section
3.04, or if the Borrower is required to pay any additional amount to any Term Lender or any
Governmental Authority for the account of any Term Lender pursuant to Section 3.01, or if
any Term Lender is a Defaulting Lender, or if any circumstance exists under the last paragraph of
Section 10.01 that gives the Borrower the right to replace a Term Lender as a party hereto,
then the Borrower may, at its sole expense and effort, upon notice to such Term Lender and the
Administrative Agent, require such Term Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in, and consents required by, Section
10.06), all of its interests, rights and obligations under this Agreement and the related Loan
Documents to an assignee that shall assume such obligations (which assignee may be another Term
Lender, if a Term Lender accepts such assignment); provided that:

     (a) the Borrower shall have paid to the Administrative Agent the assignment fee specified in
Section 10.06(b);

     (b) such Term Lender shall have received payment of an amount equal to the outstanding
principal of its Term Loans, accrued interest thereon, accrued fees and all other amounts payable
to it hereunder and under the other Loan Documents (including any amounts

73

 

under Section 3.05) from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts);

     (c) in the case of any such assignment resulting from a claim for compensation under
Section 3.04 or payments required to be made pursuant to Section 3.01, such
assignment will result in a reduction in such compensation or payments thereafter; and

     (d) such assignment does not conflict with applicable Laws.

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

     10.14 Governing Law; Jurisdiction; Etc.

     (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK.

     (b) SUBMISSION TO JURISDICTION. EACH OF THE PARTIES HERETO IRREVOCABLY AND
UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE
COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT
OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR FOR
RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND
UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN
SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR
PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT
OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT OR IN ANY OTHER LOAN DOCUMENT
SHALL AFFECT ANY RIGHT THAT ANY OF THE PARTIES HERETO MAY OTHERWISE HAVE TO BRING ANY ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST ANY OTHER PARTY HERETO OR
THEIR RESPECTIVE PROPERTIES IN THE COURTS OF ANY JURISDICTION.

     (c) WAIVER OF VENUE. EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (b) OF THIS
SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT

74

 

PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH
ACTION OR PROCEEDING IN ANY SUCH COURT.

     (d) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS
IN THE MANNER PROVIDED FOR NOTICES IN SECTION 10.02. NOTHING IN THIS AGREEMENT WILL AFFECT
THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

     10.15 Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, 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). EACH PARTY HERETO (A) 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 (B) 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.

     10.16 No Advisory or Fiduciary Responsibility. In connection with all aspects of each
transaction contemplated hereby (including in connection with any amendment, waiver or other
modification hereof or of any other Loan Document), each of the Borrower and the Parent
acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (i) (A) the
arranging and other services regarding this Agreement provided by the Administrative Agent and the
Book Managers are arm’s-length commercial transactions between the Parent, the Borrower and their
respective Affiliates, on the one hand, and the Administrative Agent and the Book Managers, on the
other hand, (B) each of the Borrower and the Parent has consulted its own legal, accounting,
regulatory and tax advisors to the extent it has deemed appropriate, and (C) each of the Borrower
and the Parent is capable of evaluating, and understands and accepts, the terms, risks and
conditions of the transactions contemplated hereby and by the other Loan Documents; (ii) (A) the
Administrative Agent and the Book Managers each is and has been acting solely as a principal and,
except as expressly agreed in writing by the relevant parties, has not been, is not, and will not
be acting as an advisor, agent or fiduciary for the Borrower, the Parent or any of their respective
Affiliates, or any other Person and (B) neither the Administrative Agent nor any Book Manager has
any obligation to the Borrower, the Parent or any of their respective Affiliates with respect to
the transactions contemplated hereby except those obligations expressly set forth herein and in the
other Loan Documents; and (iii) the Administrative Agent and the Book Managers and their respective
Affiliates may be engaged in a broad range of transactions that involve interests that differ from
those of the Borrower, the Parent and their respective Affiliates, and neither the Administrative
Agent nor any Book Manager has any obligation to disclose any of such interests to the Borrower,
the Parent or any of their respective Affiliates. To the fullest extent permitted by law, each of
the Borrower and

75

 

the Parent hereby waives and releases any claims that it may have against the Administrative
Agent and the Book Managers with respect to any breach or alleged breach of agency or fiduciary
duty in connection with any aspect of any transaction contemplated hereby.

     10.17 Electronic Execution of Assignments and Certain Other Documents. The words “execution,”
“signed,” “signature,” and words of like import in any Assignment and Assumption or in any
amendment or other modification hereof (including waivers and consents) shall be deemed to include
electronic signatures or the keeping of records in electronic form, each of which shall be of the
same legal effect, validity or enforceability as a manually executed signature or the use of a
paper-based recordkeeping system, as the case may be, to the extent and as provided for in any
applicable law, including the Federal Electronic Signatures in Global and National Commerce Act,
the New York State Electronic Signatures and Records Act, or any other similar state laws based on
the Uniform Electronic Transactions Act.

     10.18 USA PATRIOT Act. Each Term Lender that is subject to the Act (as hereinafter defined)
and the Administrative Agent (for itself and not on behalf of any Term Lender) hereby notifies the
Borrower and the Parent that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub.
L. 107-56 (signed into law October 26, 2001)) (the “USA Patriot Act”), it is required to
obtain, verify and record information that identifies the Borrower and the Parent, which
information includes the name and address of the Borrower and of the Parent, and other information
that will allow such Term Lender or the Administrative Agent, as applicable, to identify the
Borrower or the Parent, as applicable, in accordance with the USA Patriot Act. Each of the
Borrower and the Parent shall, promptly following a request by the Administrative Agent or any Term
Lender, provide all documentation and other information that the Administrative Agent or such Term
Lender requests in order to comply with its ongoing obligations under applicable “know your
customer” and anti-money laundering rules and regulations, including the USA Patriot Act.

ARTICLE II

The Credits

     Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each
Lender agrees to make Loans to the Borrower during the Availability Period in an aggregate
principal amount that will not result in (a) such Lender’s Revolving Credit Exposure exceeding such
Lender’s Commitment or (b) the total Revolving Credit Exposures exceeding the total Commitments.
Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower
may borrow, repay and reborrow the Loans.

     Section 2.02 Loans and Borrowings.

          (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing
consisting of Loans made by the Lenders ratably in accordance with their respective Commitments.
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 are several and no
Lender shall be responsible for any other Lender’s failure to make Loans as required.

          (b) Types of Loans. Subject to Section 3.03, each Borrowing shall be comprised
entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each
Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or
Affiliate of such Lender to make such Loan; provided that any exercise of such option shall
not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this
Agreement.

          (c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each
Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that
is an integral multiple of $1,000,000 and not less than $1,000,000. At the time that each ABR
Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of
$1,000,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an
aggregate amount that is equal to the entire unused balance of the total Commitments or that is
required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.08(e).
Borrowings of more than one Type may be outstanding at the same time; provided that there
shall not at any time be more than a total of eight (8) Eurodollar Borrowings outstanding.
Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to
request, or to elect to convert or continue, any Borrowing if the Interest Period requested with
respect thereto would end after the Maturity Date.

          (d) Notes. The Loans made by each Lender shall be evidenced by a single promissory
note of the Borrower in substantially the form of Exhibit A, dated, in the case of (i) any Lender
party hereto as of the date of this Agreement, as of the date of this Agreement, or (ii) any Lender
that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of
the Assignment and Assumption, payable to the order of such Lender in a principal amount equal to
its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event
that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to
Section 2.06, Section 12.04(a) or otherwise), the Borrower shall deliver or cause to be delivered
on the effective date of such increase or decrease, a new

21

 

Note payable to the order of such Lender in a principal amount equal to its Maximum Credit
Amount after giving effect to such increase or decrease, and otherwise duly completed. The date,
amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender,
and all payments made on account of the principal thereof, shall be recorded by such Lender on its
books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule
attached to such Note or any continuation thereof or on any separate record maintained by such
Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or
the Borrower’s rights or obligations in respect of such Loans or affect the validity of such
transfer by any Lender of its Note.

     Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall
notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar
Borrowing, not later than 12:00 noon, New York City time, three Business Days before the date of
the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 12:00 noon, New York
City time, one Business Day before the date of the proposed Borrowing; provided that no
such notice shall be required for any deemed request of an ABR Borrowing to finance the
reimbursement of an LC Disbursement as provided in Section 2.08(e). Each such telephonic Borrowing
Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent of a written Borrowing Request in substantially the form of Exhibit B and
signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the
following information in compliance with Section 2.02:

which shall comply with the requirements of Section 2.05.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an
ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar
Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s
duration. Each Borrowing Request shall constitute a representation that the amount of the
requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total
Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective
Borrowing Base).

22

 

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the
Administrative Agent shall advise each Lender of the details thereof and of the amount of such
Lender’s Loan to be made as part of the requested Borrowing.

     Section 2.04 Interest Elections.

          (a) Conversion and Continuance. Each Borrowing initially shall be of the Type
specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower
may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the
case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this
Section 2.04. The Borrower may elect different options with respect to different portions of the
affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders
holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be
considered a separate Borrowing.

          (b) Interest Election Requests. To make an election pursuant to this Section 2.04,
the Borrower shall notify the Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing
of the Type resulting from such election to be made on the effective date of such election. Each
such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by
hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in
substantially the form of Exhibit C and signed by the Borrower.

          (c) Information in Interest Election Requests. Each telephonic and written Interest
Election Request shall specify the following information in compliance with Section 2.02:

               (i) the Borrowing to which such Interest Election Request applies and, if different options
are being elected with respect to different portions thereof, the portions thereof to be allocated
to each resulting Borrowing (in which case the information to be specified pursuant to Section
2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing);

               (ii) the effective date of the election made pursuant to such Interest Election Request, which
shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period contemplated by
the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one
month’s duration.

23

 

          (d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an
Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing.

          (e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default
and Borrowing Base Deficiencies on Interest Election. If the Borrower fails to deliver a
timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the
Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at
the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing.
Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base
Deficiency has occurred and is continuing: (i) no outstanding Borrowing may be converted to or
continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion
of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be
ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR
Borrowing at the end of the Interest Period applicable thereto.

     Section 2.05 Funding of Borrowings.

          (a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder
on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York
City time, to the account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the
Borrower by promptly crediting the amounts so received, in like funds, to an account of the
Borrower maintained with the Administrative Agent in Houston, Texas and designated by the Borrower
in the applicable Borrowing Request; provided that ABR Loans made to finance the
reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the
Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any Lender to
obtain the funds for its Loan in any particular place or manner or to constitute a representation
by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or
manner.

          (b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender’s share of such Borrowing, the
Administrative Agent may assume that such Lender has made such share available on such date in
accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the
Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the
applicable Borrowing available to the Administrative Agent, then the applicable Lender and the
Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding
amount with interest thereon, for each day from and including the date such amount is made
available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i)
in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined
by the Administrative Agent in accordance with banking industry rules on interbank compensation or
(ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays
such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan
included in such Borrowing.

24

 

     Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts.

          (a) Scheduled Termination of Commitments. Unless previously terminated, the

Amounts or the Borrowing Base is terminated or reduced to zero, then the Commitments shall
terminate on the effective date of such termination or reduction.

          (b) Optional Termination and Reduction of Aggregate Credit Amounts.

               (i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Maximum
Credit Amounts; provided that (A) each reduction of the Aggregate Maximum Credit Amounts
shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and
(B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts if, after
giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the
total Revolving Credit Exposures would exceed the total Commitments.

               (ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce
the Aggregate Maximum Credit Amounts under Section 2.06(b)(i) at least three Business Days prior to
the effective date of such termination or reduction, specifying such election and the effective
date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section
2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit
Amounts shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum
Credit Amounts pursuant to this Section 2.06(b)(ii) shall be made ratably among the Lenders in
accordance with each Lender’s Applicable Percentage.

     Section 2.07 Borrowing Base.

          (a) Initial Borrowing Base. For the period from and including the Effective Date to
but excluding the first Redetermination Date, the amount of the Borrowing Base shall be
$150,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further
adjustments from time to time pursuant to Section 8.13(c), Section 8.16 or Section 9.12(d).

          (b) Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined
semi-annually in accordance with this Section 2.07 (a “Scheduled Redetermination”), and,
subject to Section 2.07(d), such redetermined Borrowing Base shall become effective and applicable
to the Borrower, the Agents, the Issuing Bank and the Lenders on March 31st and
September 30th of each year, commencing March 31, 2009. In addition, the
Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at
the direction of the Required Lenders, by notifying the Borrower thereof, two times during any
12-month period, each elect to cause the Borrowing Base to be redetermined between Scheduled
Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07.

25

 

     (c) Scheduled and Interim Redetermination Procedure.

               (i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as
follows: Upon receipt by the Administrative Agent of (A) the Reserve Report and the certificate
required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled
Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim
Redetermination, pursuant to Section 8.12(b) and (c), and (B) such other reports, data and
supplemental information, including, without limitation, the information provided pursuant to
Section 8.12(c), as may, from time to time, be reasonably requested by the Required Lenders (the
Reserve Report, such certificate and such other reports, data and supplemental information being
the “Engineering Reports”), the Administrative Agent shall evaluate the information
contained in the Engineering Reports and shall, in its sole discretion, propose a new Borrowing
Base (the “Proposed Borrowing Base”) based upon such information and such other information
(including, without limitation, the status of title information with respect to the Oil and Gas
Properties as described in the Engineering Reports and the existence of any other Debt) as the
Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil
and gas lending criteria as it exists at the particular time. In no event shall the Proposed
Borrowing Base exceed the Aggregate Maximum Credit Amounts.

               (ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed
Borrowing Base (the “Proposed Borrowing Base Notice”):

                    (A) in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have
received the Engineering Reports required to be delivered by the Borrower pursuant to Section
8.12(a) and (c) in a timely and complete manner, then on or before the March 15th and September
15th of such year following the date of delivery or (2) if the Administrative Agent shall not have
received the Engineering Reports required to be delivered by the Borrower pursuant to Section
8.12(a) and (c) in a timely and complete manner, then promptly after the Administrative Agent has
received complete Engineering Reports from the Borrower and has had a reasonable opportunity to
determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i); and

                    (B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15)
days after the Administrative Agent has received the required Engineering Reports.

               (iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must
be approved or deemed to have been approved by all of the Lenders as provided in this Section
2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base
then in effect must be approved or be deemed to have been approved by the Required Lenders as
provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each
Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the
Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such fifteen
(15) days, any Lender has not communicated its approval or disapproval in writing to the
Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing
Base. If, at the end of such 15-day

26

 

period, all of the Lenders, in the case of a Proposed Borrowing Base that would increase the
Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base
that would decrease or maintain the Borrowing Base then in effect, have approved or deemed to have
approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base,
effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period,
all of the Lenders or the Required Lenders, as applicable, have not approved or deemed to have
approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the
highest Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required
Lenders and, so long as such amount does not increase the Borrowing Base then in effect, such
amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d).

          (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing
Base is approved or is deemed to have been approved by all of the Lenders or the Required Lenders,
as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower
and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base
Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the
Borrower, the Administrative Agent, the Issuing Bank and the Lenders:

               (i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have
received the Engineering Reports required to be delivered by the Borrower pursuant to Section
8.12(a) and (c) in a timely and complete manner, then on the March 31st or September 30th, as
applicable, following such notice, or (B) if the Administrative Agent shall not have received the
Engineering Reports required to be delivered by the Parent pursuant to Section 8.12(a) and (c) in a
timely and complete manner, then on the Business Day next succeeding delivery of such notice; and

               (ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery
of such notice.

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the
next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section
8.13(c), Section 8.16 or Section 9.12(d), whichever occurs first. Notwithstanding the foregoing,
no Scheduled Redetermination or Interim Redetermination shall become effective until the New
Borrowing Base Notice related thereto is received by the Borrower.

     Section 2.08 Letters of Credit.

          (a) General. Subject to the terms and conditions set forth herein, the Borrower may
request the issuance of dollar denominated Letters of Credit for its own account or for the account
of the Parent or any of the Subsidiaries, in a form reasonably acceptable to the Administrative
Agent and the Issuing Bank, at any time and from time to time during the Availability Period;
provided that the Borrower may not request the issuance, amendment, renewal or extension of
Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a
result thereof. In the event of any inconsistency between the terms and conditions of this
Agreement and the terms and conditions of any form of letter of credit

27

 

application or other agreement submitted by the Borrower to, or entered into by the Borrower
with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement
shall control.

          (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter
of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication,
if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the
Administrative Agent (not less than three (3) Business Days in advance of the requested date of
issuance, amendment, renewal or extension) a notice:

               (i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be
amended, renewed or extended;

               (ii) specifying the date of issuance, amendment, renewal or extension (which shall be a
Business Day);

               (iii) specifying the date on which such Letter of Credit is to expire (which shall comply with
Section 2.08(c));

               (iv) specifying the amount of such Letter of Credit;

               (v) specifying the name and address of the beneficiary thereof and such other information as
shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

               (vi) specifying the amount of the then effective Borrowing Base and whether a Borrowing Base
Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to the
requested Letter of Credit or the requested amendment, renewal or extension of an outstanding
Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the
requested Letter of Credit or the requested amendment, renewal or extension of an outstanding
Letter of Credit).

Each notice shall constitute a representation that after giving effect to the requested issuance,
amendment, renewal or extension, as applicable, (i) the LC Exposure shall not exceed the LC
Commitment and (ii) the total Revolving Credit Exposures shall not exceed the total Commitments
(i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on
the Issuing Bank’s standard form in connection with any request for a Letter of Credit.

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earlier of (i) the date one year after the date of the issuance of such Letter of
Credit (or, in the case of any renewal or extension thereof, one year after such renewal or
extension) and (ii) the date that is five Business Days prior to the Maturity Date.

28

 

          (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the
Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby
acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s
Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit.
In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank,
such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not
reimbursed by the Borrower on the date due as provided in Section 2.08(e), or of any reimbursement
payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and
agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of
Letters of Credit is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence
and continuance of a Default, the existence of a Borrowing Base Deficiency or reduction or
termination of the Commitments, and that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever.

          (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative
Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the
date that such LC Disbursement is made, if the Borrower shall have received notice of such LC
Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been
received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York
City time, on (i) the Business Day that the Borrower receives such notice, if such notice is
received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day
immediately following the day that the Borrower receives such notice, if such notice is not
received prior to such time on the day of receipt; provided that if such LC Disbursement is
not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth
herein, be deemed to have requested, and the Borrower does hereby request under such circumstances,
that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so
financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the
resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative
Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the
Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following
receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage
of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with
respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the
payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing
Bank the amounts so received by it from the Lenders. Promptly following receipt by the
Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the
Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that
Lenders have made payments pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to
such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender
pursuant to this Section 2.08(e) to reimburse the Issuing Bank for any LC Disbursement (other than
the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve
the Borrower of its obligation to reimburse such LC Disbursement.

29

 

          (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as
provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit,
any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft
or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in
any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by
the Issuing Bank under a Letter of Credit against presentation of a draft or other document that
does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv)
any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that
might, but for the provisions of this Section 2.08(f), constitute a legal or equitable discharge
of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the
Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have
any liability or responsibility by reason of or in connection with the issuance or transfer of any
Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to in the preceding sentence), or any error, omission, interruption,
loss or delay in transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a drawing thereunder),
any error in interpretation of technical terms or any consequence arising from causes beyond the
control of the Issuing Bank; provided that the foregoing shall not be construed to excuse
the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the Borrower to the extent
permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure
to exercise care when determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of
gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a
court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised all requisite
care in each such determination. In furtherance of the foregoing and without limiting the
generality thereof, the parties agree that, with respect to documents presented which appear on
their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank
may, in its sole discretion, either accept and make payment upon such documents without
responsibility for further investigation or refuse to accept and make payment upon such documents
if such documents are not in strict compliance with the terms of such Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of
Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by
telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made
or will make an LC Disbursement thereunder; provided that any failure to give or delay in
giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank
and the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until
the Borrower shall have reimbursed the Issuing Bank for such LC Disbursement (either with its own
funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for
each day from and including the date such LC Disbursement is made to

30

 

but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per
annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for
the account of the Issuing Bank, except that interest accrued on and after the date of payment by
any Lender pursuant to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of
such Lender to the extent of such payment.

               (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement
of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall
pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section
3.05(a). From and after the effective date of any such replacement, (i) the successor Issuing Bank
shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to
Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing
Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such
successor and all previous Issuing Banks, as the context shall require. After the replacement of
the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of the Issuing Bank under this Agreement with
respect to Letters of Credit issued by it prior to such replacement, but shall not be required to
issue additional Letters of Credit.

               (j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing
and the Borrower receives notice from the Administrative Agent or the Required Lenders demanding
the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required
to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any
prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the
Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders,
an amount in cash equal to, in the case of an Event of Default, the LC Exposure, and in the case of
a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as
of such date plus any accrued and unpaid interest thereon; provided that the obligation to
deposit such cash collateral shall become effective immediately, and such deposit shall become
immediately due and payable, without demand or other notice of any kind, upon the occurrence of any
Event of Default with respect to the Borrower or any Subsidiary described in Section 10.01(h) or
Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of the
Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security
interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if
any, from time to time deposited or held in such account, all deposits or wire transfers made
thereto, any and all investments purchased with funds deposited in such account, all interest,
dividends, cash, instruments, financial assets and other Property from time to time received,
receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and
all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any
substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to
this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary
of any such Letter of Credit has attempted to draw down all or a portion of such amount under the
terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be
subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the
Parent or any of its

31

 

Subsidiaries may now or hereafter have against any such beneficiary, the Issuing Bank, the
Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit
shall be held as collateral securing the payment and performance of the Borrower’s and the
Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative
Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over
such account. Other than any interest earned on the investment of such deposits, which investments
shall be made in the items described in Section 9.05(c), (d), (e) and (f) and at the Borrower’s
direction, risk and expense, such deposits shall not bear interest. Interest or profits, if any,
on such investments shall accumulate in such account. Moneys in such account shall be applied by
the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not
been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the
reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of
the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the
Guarantors under this Agreement or the other Loan Documents. If the Borrower is required to
provide an amount of cash collateral hereunder as a result of the occurrence of an Event of
Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess
attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then
such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three
Business Days after all Events of Default have been cured or waived.

ARTICLE III

Payments of Principal and Interest; Prepayments; Fees

     Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay
to the Administrative Agent for the account of each Lender the then unpaid principal amount of each
Loan on the Termination Date.

     Section 3.02 Interest.

          (a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the
Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (c) Post-Default Rate. Notwithstanding the foregoing, if an Event of Default has
occurred and is continuing, or if any principal of or interest on any Loan or any fee or other
amount payable by the Borrower or any Guarantor hereunder or under any other Loan Document is not
paid when due, whether at stated maturity, upon acceleration or otherwise, and including any
payments in respect of a Borrowing Base Deficiency under Section 3.04(c), then all Loans
outstanding, in the case of an Event of Default, and such overdue amount, in the case of a failure
to pay amounts when due, shall bear interest, after as well as before judgment, at a rate per annum
equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but
in no event to exceed the Highest Lawful Rate.

32

 

          (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and on the Termination Date; provided that (i)
interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) in the event of any
repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior to the
Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on
the date of such repayment or prepayment, and (iii) in the event of any conversion of any
Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such
Loan shall be payable on the effective date of such conversion.

          (e) Interest Rate Computations. All interest hereunder shall be computed on the basis
of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case
interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except
that interest computed by reference to the Alternate Base Rate at times when the Alternate Base
Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days
in a leap year), and in each case shall be payable for the actual number of days elapsed (including
the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate
or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error, and be binding upon the parties hereto.

     Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest
Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO
Rate or the LIBO Rate for such Interest Period; or

          (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or
LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost
to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest
Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent
notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer
exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR
Borrowing.

     Section 3.04 Prepayments.

          (a) Optional Prepayments. The Borrower shall have the right at any time and from time
to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with
Section 3.04(b).

          (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the
Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the
case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City

33

 

time, three Business Days before the date of prepayment, or (ii) in the case of prepayment of
an ABR Borrowing, not later than 12:00 noon, New York City time, one Business Day before the date
of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of
any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the
contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be
permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02.
Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid
Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section
3.02 and any amounts due under Section 5.02.

          (c) Mandatory Prepayments.

               (i) If, after giving effect to any termination or reduction of the Aggregate Maximum Credit
Amounts pursuant to Section 2.06(b), the total Revolving Credit Exposures exceeds the total
Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such termination or
reduction in an aggregate principal amount equal to such excess, and (B) if any excess remains
after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative
Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as
provided in Section 2.08(j).

               (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in
accordance with Section 2.07 or Section 8.13(c), if the total Revolving Credit Exposures exceeds
the redetermined or adjusted Borrowing Base, then the Borrower shall (A) prepay the Borrowings in
an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying
all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of
the Lenders an amount equal to such excess to be held as cash collateral as provided in Section
2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral
within forty-five (45) days following its receipt of the New Borrowing Base Notice in accordance
with Section 2.07(d) or the date the adjustment occurs; provided that all payments required
to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date.

               (iii) Upon any adjustments to the Borrowing Base pursuant to Section 9.12(d), if the total
Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A)
prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess
remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the
Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash
collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment
and/or deposit of cash collateral on the date the Parent or any Subsidiary receives cash proceeds
as a result of such disposition; provided that all payments required to be made pursuant to
this Section 3.04(c)(iii) must be made on or prior to the Termination Date.

               (iv) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first,
ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then
outstanding, and if more than one Eurodollar Borrowing is then

34

 

outstanding, to each such Eurodollar Borrowing in order of priority beginning with the
Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable
thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the
Interest Period applicable thereto.

               (v) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to
the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 3.04(c) shall
be accompanied by accrued interest to the extent required by Section 3.02.

          (d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04
shall be without premium or penalty, except as required under Section 5.02.

     Section 3.05 Fees.

          (a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the
account of each Lender a commitment fee, which shall accrue at the applicable Commitment Fee Rate
on the average daily amount of the unused amount of the Commitment of such Lender during the period
from and including the date of this Agreement to but excluding the Termination Date. Accrued
commitment fees shall be payable in arrears on the last day of March, June, September and December
of each year and on the Termination Date, commencing on the first such date to occur after the date
hereof. All commitment fees shall be computed on the basis of a year of 360 days, unless such
computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the
basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

          (b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent
for the account of each Lender a participation fee with respect to its participations in Letters of
Credit, which shall accrue at the same Applicable Margin used to determine the interest rate
applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding
any portion thereof attributable to unreimbursed LC Disbursements) during the period from and
including the date of this Agreement to but excluding the later of the date on which such Lender’s
Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to the
Issuing Bank a fronting fee, which shall accrue at the rate of 0.250% per annum on the average
daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the period from and including the date of this Agreement to but excluding the
later of the date of termination of the Commitments and the date on which there ceases to be any LC
Exposure; provided that in no event shall such fee be less than $500 during any quarter,
and (iii) to the Issuing Bank, for its own account, its standard fees with respect to the issuance,
amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder.
Participation fees and fronting fees accrued through and including the last day of March, June,
September and December of each year shall be payable on the third Business Day following such last
day, commencing on the first such date to occur after the date of this Agreement; provided
that all such fees shall be payable on the Termination Date and any such fees accruing after the
Termination Date shall be payable on demand. Any other fees payable to the Issuing Bank

35

 

pursuant to this Section 3.05(a) shall be payable within 10 days after demand. All
participation fees and fronting fees shall be computed on the basis of a year of 360 days, unless
such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on
the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

          (c) Administrative Agent Fees. The Borrower agrees to pay to the Administrative
Agent, for its own account, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Administrative Agent.

          (d) Borrowing Base Increase Fees. The Borrower agrees to pay to the Administrative
Agent, for the account of each Lender then party to this Agreement, ratably in accordance with its
Applicable Percentage, a Borrowing Base increase fee, to be agreed by the Lenders and the Borrower,
on the amount of any increase of the Borrowing Base over the highest Borrowing Base previously in
effect, payable on the effective date of any such increase to the Borrowing Base.

          (e) Defaulting Lender Fees. The Borrower shall not be obligated to pay the
Administrative Agent any Defaulting Lender’s ratable share of the fees described in Section 3.05(a)
and (b) for the period commencing on the day such Defaulting Lender becomes a Defaulting Lender and
continuing for so long as such Lender continues to be a Defaulting Lender.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs

     Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

          (a) Payments by the Borrower. The Borrower shall make each payment required to be
made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or
of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00
noon, New York City time, on the date when due, in immediately available funds, without defense,
deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall
not be refundable under any circumstances. Any amounts received after such time on any date may,
in the discretion of the Administrative Agent, be deemed to have been received on the next
succeeding Business Day for purposes of calculating interest thereon. All such payments shall be
made to the Administrative Agent at its offices specified in Section 12.01, except payments to be
made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to
Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons
entitled thereto. The Administrative Agent shall distribute any such payments received by it for
the account of any other Person to the appropriate recipient promptly following receipt thereof.
If any payment hereunder shall be due on a day that is not a Business Day, the date for payment
shall be extended to the next succeeding Business Day, and, in the case of any payment accruing
interest, interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

36

 

          (b) Application of Insufficient Payments. If at any time insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal,
unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to such parties, and
(ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

          (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of
set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment
of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements
and accrued interest thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value) participations in the
Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans and participations
in LC Disbursements; provided that (i) if any such participations are purchased and all or
any portion of the payment giving rise thereto is recovered, such participations shall be rescinded
and the purchase price restored to the extent of such recovery, without interest, and (ii) the
provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the
Borrower pursuant to and in accordance with the express terms of this Agreement or any payment
obtained by a Lender as consideration for the assignment of or sale of a participation in any of
its Loans or participations in LC Disbursements to any assignee or participant, other than to the
Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c)
shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively
do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the Borrower in the amount
of such participation.

     Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent
shall have received notice from the Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not
make such payment, the Administrative Agent may assume that the Borrower has made such payment on
such date in accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower
has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may
be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Lender or Issuing Bank with interest thereon, for each day from and including
the date such amount is distributed to it to but excluding the date of payment to the
Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by
the Administrative Agent in accordance with banking industry rules on interbank compensation.

37

 

     Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall be a
Defaulting Lender because of its failure to make any payment required to be made by it pursuant to
Section 2.05(b), Section 2.08(d), Section 2.08(e) or Section 4.02, then the Administrative Agent
may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Defaulting Lender to
satisfy such Defaulting Lender’s obligations under such Sections until all such unsatisfied
obligations are fully paid.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment
by the Borrower and/or the Guarantors unto and in favor of the Administrative Agent for the benefit
of the Lenders of all of the Borrower’s or each Guarantor’s interest in and to production and all
proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property.
The Security Instruments further provide in general for the application of such proceeds to the
satisfaction of the Indebtedness and other obligations described therein and secured thereby.
Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an
Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify
the purchaser or purchasers of such production nor take any other action to cause such proceeds to
be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such
proceeds to be paid to the Borrower and the Guarantors and (b) the Lenders hereby authorize the
Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to
the Borrower and/or the Guarantors.

ARTICLE V

Increased Costs; Break Funding Payments; Taxes

     Section 5.01 Increased Costs.

          (a) Eurodollar Changes in Law. If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of, or credit extended by, any Lender (except
any such reserve requirement reflected in the Adjusted LIBO Rate); or

               (ii) impose on any Lender or the London interbank market any other condition affecting this
Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to
reduce the amount of any sum received or receivable by such Lender (whether of principal, interest
or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

          (b) Capital Requirements. If any Lender or the Issuing Bank determines that any
Change in Law regarding capital requirements has or would have the effect of reducing the rate of
return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the
Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or
participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the
Issuing Bank, to a level below that which such Lender or the Issuing Bank or such

38

 

Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law
(taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such
Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to
time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional
amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the
Issuing Bank’s holding company for any such reduction suffered.

          (c) Certificates. A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company,
as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the Borrower and
shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank,
as the case may be, the amount shown as due on any such certificate within 10 days after receipt
thereof.

          (d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the
part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall
not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation.

     Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal
of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto
(including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an
ABR Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure
to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice
delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day
of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to
Section 5.04, then, in any such event, the Borrower shall compensate each Lender for the loss, cost
and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or
expense to any Lender shall be deemed to include an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest which would have accrued on the principal amount of
such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to
such Loan, for the period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Loan), over (ii) the amount of interest which would
accrue on such principal amount for such period at the interest rate which such Lender would bid
were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and
period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such
certificate within 10 days after receipt thereof.

39

 

     Section 5.03 Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of the Borrower or any Guarantor under any Loan Document shall be made free and
clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that
if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes
from such payments, then (i) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums payable under this
Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower
or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the
full amount deducted to the relevant Governmental Authority in accordance with applicable law.

          (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

          (c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative
Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the
Issuing Bank, as the case may be, on or with respect to any payment by or on account of any
obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified
Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental
Authority. A certificate of the Administrative Agent, a Lender or the Issuing Bank as to the
amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and
shall be conclusive absent manifest error.

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

          (e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or
any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or
any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Borrower as will permit such payments
to be made without withholding or at a reduced rate.

     Section 5.04 Mitigation Obligations; Replacement of Defaulting Lenders.

          (a) Designation of Different Lending Office. If any Lender requests compensation
under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or
any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender
shall use reasonable efforts to designate a different lending office for funding or booking its
Loans hereunder or to assign its rights and obligations hereunder to

40

 

another of its offices, branches or affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or
Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The
Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

          (b) Replacement of Defaulting Lenders. If any Lender becomes a Defaulting Lender,
then the Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance
with and subject to the restrictions contained in Section 12.04(a)), all its interests, rights and
obligations under this Agreement to an assignee that shall assume such obligations (which assignee
may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall
have received the prior written consent of the Administrative Agent, which consent shall not
unreasonably be withheld and (ii) such Lender shall have received payment of an amount equal to the
outstanding principal of its Loans and participations in LC Disbursements, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the
extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of
all other amounts).

and each Guarantor’s corporate powers and have been duly authorized by all necessary corporate
and, if required, stockholder action (including, without limitation, any action required to be
taken by any class of directors of the Parent, the Borrower or any other Person, whether interested
or disinterested, in order to ensure the due authorization of the Transactions). Each Loan
Document to which the Borrower and each Guarantor is a party has been duly executed and delivered
by the Borrower and such Guarantor and constitutes a legal, valid and binding obligation of the
Borrower and such Guarantor, as applicable, enforceable in accordance with its terms, subject to

or approval of, registration or filing with, or any other action by, any Governmental Authority or
any other third Person (including shareholders or any class of directors, whether interested or
disinterested, of the Parent, the Borrower or any other Person), nor is any such consent, approval,
registration, filing or other action necessary for the validity or enforceability of any Loan
Document or the consummation of the transactions contemplated thereby, except such as have been
obtained or made and are in full force and effect other than (i) the recording and filing of the
Security Instruments as required by this Agreement and (ii) those third party approvals or consents
which, if not made or obtained, would not cause a Default hereunder, could not reasonably be
expected to have a Material Adverse Effect or do not have an adverse effect on the enforceability
of the Loan Documents, (b) will not violate any applicable law or regulation or the charter,
by-laws or other organizational documents of it or any of its Subsidiaries or any order of any
Governmental Authority, (c) will not violate or result in a default under any indenture, agreement
or other instrument binding upon it or any of its Subsidiaries or its Properties, or give rise to a
right thereunder to require any payment to be made by it or such Subsidiary and (d) will not result
in the creation or imposition of any Lien on any Property of it or any of its Subsidiaries (other
than the Liens created by the Loan Documents).

     Section 7.04 Financial Condition; No Material Adverse Change.

          (a) The Parent has heretofore furnished to the Lenders its consolidated balance sheet and

     Section 7.10 ERISA.

          (a) The Borrower, each of the Borrower’s Subsidiaries and each ERISA Affiliate have complied

misstatement of fact or omits to state any material fact necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading; provided
that, with respect to projected financial information, it represents only that such information was
prepared in good faith based upon assumptions believed to be reasonable at the time. There is no
fact peculiar to it or any of its Subsidiaries which could reasonably be expected to have a
Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and
which has not been set forth in this Agreement or the Loan Documents or the other documents,
certificates and statements furnished to the Administrative Agent or the Lenders by or on behalf of
it or any of its Subsidiaries prior to, or on, the date hereof in connection with the transactions
contemplated hereby. There are no statements or conclusions in any Reserve Report which are based
upon or include misleading information or fail to take into account material information regarding
the matters reported therein, it being understood that projections concerning volumes attributable
to the Oil and Gas Properties of it and its Subsidiaries and production and cost estimates
contained in each Reserve Report are necessarily based upon professional opinions, estimates and
projections and that it and its Subsidiaries do not warrant that such opinions, estimates and
projections will ultimately prove to have been accurate.

Administrative Agent and the Lenders have been named as additional insureds in respect of said
insurance policies insuring against physical damage to equipment and facilities owned by the

Lease), or subject to any order, judgment, writ or decree, which either restricts or purports to
restrict its ability to grant Liens to the Administrative Agent and the Lenders on or in respect of
their Properties to secure the Indebtedness and the Loan Documents.

     Section 7.14 Subsidiaries. Except as set forth on Schedule 7.14 or as disclosed in

     Section 7.16 Properties; Titles, Etc.

          (a) The Borrower and the Borrower’s Subsidiaries each has good and defensible title to the Oil
and Gas Properties evaluated in the most recently delivered Reserve Report and good title to all
its personal Properties, in each case, free and clear of all Liens except Liens permitted by
Section 9.03. After giving full effect to the Excepted Liens, the Borrower or any of the
Borrower’s Subsidiaries specified as the owner owns the net interests in production attributable to
the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the
ownership of such Properties shall not in any material respect obligate the Borrower or such
Subsidiary to bear the costs and expenses relating to the maintenance, development and operations
of each such Property in an amount in excess of the working interest of each Property set forth in
the most recently delivered Reserve Report that is not offset by a corresponding proportionate
increase the Borrower’s or such Subsidiary’s net revenue interest in such Property.

          (b) All material leases and agreements necessary for the conduct of the business of the
Borrower and the Borrower’s 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

expected to have a Material Adverse Effect.

          (c) The rights and Properties presently owned, leased or licensed by the Borrower and the
Borrower’s Subsidiaries including, without limitation, all easements and rights of way, include all
rights and Properties necessary to permit the Borrower and the Borrower’s Subsidiaries to conduct
their business in all material respects in the same manner as the Borrower’s business has been

          (e) The Borrower and each of the Borrower’s Subsidiaries owns, or is licensed to use, all
trademarks, tradenames, copyrights, patents and other intellectual Property material to the
Borrower’s business, and the use thereof by the Borrower and such Subsidiary does not infringe upon
the rights of any other Person, except for any such infringements that, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Borrower
and the Borrower’s Subsidiaries either own or have valid licenses or other rights to use all
databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations
and other technical information used in their businesses as presently conducted, subject to the
limitations contained in the agreements governing the use of the same, which limitations are
customary for companies engaged in the business of the exploration and production of Hydrocarbons,
with such exceptions as could not reasonably be expected to have a Material Adverse Effect.

     Section 7.17 Maintenance of Properties. Except for such acts or failures to act as
could not be reasonably expected to have a Material Adverse Effect, the Oil and Gas Properties (and
Properties unitized therewith) of the Borrower and the Borrower’s Subsidiaries have been
maintained, operated and developed in a good and workmanlike manner and in conformity with all
Governmental Requirements 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 of the Borrower and the Borrower’s Subsidiaries. Specifically
in connection with the foregoing, except for those as could not be reasonably expected to have a
Material Adverse Effect, (i) no Oil and Gas Property of the Borrower or any of the Borrower’s
Subsidiaries is subject to having allowable production reduced below the full and regular allowable
(including the maximum permissible tolerance) because of any overproduction (whether or not the
same was permissible at the time) and (ii) none of the wells comprising a part of the Oil and Gas
Properties (or Properties unitized therewith) of the Borrower or any of the Borrower’s Subsidiaries
is deviated from the vertical more than the maximum permitted by Governmental Requirements, and
such wells are, in fact, bottomed under and are producing from, and the well bores are wholly
within, the Oil and Gas Properties (or in the case of wells located on Properties unitized
therewith, such unitized Properties) of the Borrower or such Subsidiary. All pipelines, wells, gas
processing plants, platforms and other material improvements, fixtures and equipment owned in whole
or in part by the Borrower or any of the Borrower’s Subsidiaries that are necessary to conduct
normal operations are being maintained in a state adequate to conduct normal operations, and with
respect to such of the foregoing which are operated by the Borrower or any of the Borrower’s
Subsidiaries, in a manner consistent with the Borrower’s or the Borrower’s Subsidiaries’ past
practices (other than those the failure of which to maintain in accordance with this Section 7.17
could not reasonably be expected to have a Material Adverse Effect).

     Section 7.18 Gas Imbalances, Prepayments. Except as set forth on Schedule 7.18 or on
the most recent certificate delivered pursuant to Section 8.12(c), on a net basis there are no gas
imbalances, take or pay or other prepayments which would require the Borrower or any of the
Borrower’s Subsidiaries to deliver Hydrocarbons produced from their Oil and Gas Properties at some
future time without then or thereafter receiving full payment therefor exceeding one-half bcf of
gas (on an mcf equivalent basis) in the aggregate.

51

 

     Section 7.19 Marketing of Production. Except for contracts listed and in effect on
the date hereof on Schedule 7.19, and thereafter either disclosed in writing to the Administrative
Agent or included in the most recently delivered Reserve Report (with respect to all of which
contracts the Borrower represents or that the Borrower or the Borrower’s Subsidiaries are receiving
a price for all production sold thereunder which is computed substantially in accordance with the
terms of the relevant contract and are not having deliveries curtailed substantially below the
subject Property’s delivery capacity), no material agreements exist which are not cancelable on 60
days notice or less without penalty or detriment for the sale of production from the Borrower or
the Borrower’s Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights
to purchase, production, whether or not the same are currently being exercised) that (a) pertain to
the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six
(6) months from the date hereof.

Subsidiaries, the material terms thereof (including the type, term, effective date, termination
date and notional amounts or volumes), the net mark to market value thereof, all credit support
agreements relating thereto (including any margin required or supplied) and the counterparty to
each such agreement.

     Section 7.21 Use of Loans and Letters of Credit. The proceeds of the Loans and the
Letters of Credit shall be used to provide working capital for exploration and production
operations and for general corporate purposes. It and its Subsidiaries are not engaged
principally, or as one of its or their important activities, in the business of extending credit
for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock
(within the meaning of Regulation T, U or X of the Board). No part of the proceeds of any Loan or
Letter of Credit will be used for any purpose which violates the provisions of Regulations T, U or
X of the Board.

     Section 7.22 Solvency. After giving effect to the transactions contemplated hereby,
(a) the aggregate assets (after giving effect to amounts that could reasonably be received by
reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the
Borrower and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Borrower and
the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (b) each of the
Borrower and the Guarantors will not have incurred or intended to incur, and will not believe that
it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and
amounts of cash to be received by each of the Borrower and the Guarantors and the amounts to be
payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be
received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes
absolute and matures and (c) each of the Borrower and the Guarantors will not have (and will have
no reason to believe that it will have thereafter) unreasonably small capital for the conduct of
its business.

          (a) The Borrower shall at the Borrower’s sole expense: (i) comply, and shall cause the
Borrower’s Properties and operations and each of the Borrower’s Subsidiaries and each such

          (a) On or before March 1st and September 1st of each year, commencing March 1, 2009, the
Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report evaluating the
Oil and Gas Properties of the Borrower and the Borrower’s Subsidiaries as of the immediately
preceding January 1st and July 1st. The Reserve Report as of January 1 of each year shall be

shall be prepared by or under the supervision of the chief engineer of the Borrower who shall
certify such Reserve Report to be true and accurate and to have been prepared in accordance with
the procedures used in the immediately preceding January 1st Reserve Report.

          (b) In the event of an Interim Redetermination, the Borrower shall furnish to the
Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision of the
chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate and to

Borrower pursuant to Section 2.07(b), the Borrower shall provide such Reserve Report with an “as
of” date as required by the Administrative Agent as soon as possible, but in any event no later
than thirty (30) days following the receipt of such request.

          (c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative
Agent and the Lenders a certificate from a Responsible Officer certifying that in all material
respects: (i) the information contained in the Reserve Report and any other information delivered
in connection therewith is true and correct in all material respects, (ii) the Borrower or the
Borrower’s Subsidiaries owns good and defensible title to the Oil and Gas Properties evaluated in
such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section
9.03, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas
imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.18 with
respect to the Oil and Gas Properties evaluated in such Reserve Report which would require the
Borrower or any of the Borrower’s Subsidiaries to deliver Hydrocarbons either generally or produced
from such Oil and Gas Properties at some future time without then or thereafter receiving full
payment therefor, (iv) none of their Oil and Gas Properties have been sold since the date of the
last Borrowing Base determination except as set forth on an exhibit to the certificate, which
certificate shall list all of its Oil and Gas Properties sold and in such detail as reasonably
required by the Administrative Agent, (v) attached to the certificate is a list of all marketing
agreements entered into subsequent to the later of the date hereof or the most recently delivered
Reserve Report which the Borrower could reasonably be expected to have been obligated to list on
Schedule 7.19 had such agreement been in effect on the date hereof and (vi) attached thereto is a
schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged
Properties and demonstrating the percentage of the total value of the Oil and Gas Properties that
the value of such Mortgaged Properties represent in compliance with Section 8.14(a).

60

 

     Section 8.13 Title Information.

          (a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve
Report required by Section 8.12(a), the Borrower will deliver title information in form and
substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties
evaluated by such Reserve Report that were not included in the immediately preceding Reserve
Report, so that the Administrative Agent shall have received together with title information
previously delivered to the Administrative Agent, satisfactory title information on at least 85% of
the total value of the proved reserves attributable to the Oil and Gas Properties evaluated by such
Reserve Report.

          (b) If the Borrower has provided title information for additional Properties under Section
8.13(a), the Borrower shall, within 90 days of notice from the Administrative Agent that title
defects or exceptions exist with respect to such additional Properties, either (i) cure any such
title defects or exceptions (including defects or exceptions as to priority) which are not
permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged
Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens
described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii)
deliver title information in form and substance acceptable to the Administrative Agent so that the
Administrative Agent shall have received, together with title information previously delivered to
the Administrative Agent, satisfactory title information on at least 85% of the value of the Oil
and Gas Properties evaluated by such Reserve Report.

          (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent
or the Lenders to be cured within the 90-day period or the Borrower does not comply with the
requirements to provide acceptable title information covering 85% of the value of the Oil and Gas
Properties evaluated in the most recent Reserve Report, such default shall not be a Default, but
instead the Administrative Agent and/or the Required Lenders shall have the right to exercise the
following remedy in their sole discretion from time to time, and any failure to so exercise this
remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative
Agent or the Lenders. To the extent that the Administrative Agent or the Required Lenders are not
satisfied with title to any Mortgaged Property after the 90-day period has elapsed, such
unacceptable Mortgaged Property shall not count towards the 85% requirement, and the Administrative
Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base
shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in
compliance with the requirement to provide acceptable title information on 85% of the value of the
proved reserves attributable to the Oil and Gas Properties. This new Borrowing Base shall become
effective immediately after receipt of such notice.

     Section 8.14 Additional Collateral; Additional Guarantors.

          (a) In connection with each redetermination of the Borrowing Base, the Borrower shall review
the Reserve Report and the list of current Mortgaged Properties (as described in Section
8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 85% of the total
value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after
giving effect to exploration and production activities, acquisitions,

61

 

dispositions and production. In the event that the Mortgaged Properties do not represent at
least 85% of such total value, then the Borrower shall, and shall cause the Borrower’s Subsidiaries
to, grant, within thirty (30) days of delivery of the certificate required under Section 8.12(c),
to the Administrative Agent as security for the Indebtedness a first-priority Lien interest
(provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the
definition thereof may exist, but subject to the provisos at the end of such definition) on
additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such
that after giving effect thereto, the Mortgaged Properties will represent at least 85% of such
total value. All such Liens will be created and perfected by and in accordance with the provisions
of deeds of trust, security agreements and financing statements or other Security Instruments, all
in form and substance reasonably satisfactory to the Administrative Agent and in sufficient
executed (and acknowledged where necessary or appropriate) counterparts for recording purposes.

          (b) It shall promptly cause each of its Subsidiaries (other than the Borrower) to guarantee
the Indebtedness pursuant to the Guaranty Agreement. The Parent shall at all times guarantee the
Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, it shall,
or shall cause such Subsidiary to promptly (but with respect to any Subsidiary formed or acquired
after the date hereof, no later than ten (10) days after the date of such formation or
acquisition), (i) execute and deliver the Guaranty Agreement or a supplement to the Guaranty
Agreement as required by the Administrative Agent, (ii) pledge all of the Equity Interests of such
Subsidiary (including, without limitation, delivery of original certificates evidencing the Equity
Interests of such Subsidiary, together with an appropriate undated stock powers for each
certificate duly executed in blank by the registered owner thereof) and (iii) execute and deliver
such other additional closing documents, certificates and legal opinions as shall reasonably be
requested by the Administrative Agent in connection with this Section 8.14(b).

     Section 8.15 ERISA Compliance. The Borrower will promptly furnish and will cause the
Borrower’s Subsidiaries and any ERISA Affiliate to promptly furnish to the Administrative Agent (i)
promptly after the filing thereof with the United States Secretary of Labor or the Internal Revenue
Service, copies of each annual and other report with respect to each Plan or any trust created
thereunder, and (ii) immediately upon becoming aware of the occurrence of any “prohibited
transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in connection
with any Plan or any trust created thereunder, a written notice signed by the President or the
principal Financial Officer, the Subsidiary or the ERISA Affiliate, as the case may be, specifying
the nature thereof, what action the Borrower, the Borrower’s Subsidiaries or the ERISA Affiliate is
taking or proposes to take with respect thereto, and, when known, any action taken or proposed by
the Internal Revenue Service or the Department of Labor with respect thereto.

     Section 8.16 Swap Agreements. The Parent or the Borrower shall maintain the hedge
position established by the Swap Agreements identified in the most recent certificate delivered
under Section 8.01(d) during the period specified therein and shall neither assign, terminate or
unwind any such Swap Agreements nor sell any Swap Agreements if the effect of such action (when
taken together with any other Swap Agreements executed contemporaneously with the taking of such
action) would have the effect of canceling its positions under such Swap Agreements; provided that
the Parent or the Borrower may terminate or otherwise cancel or

62

 

unwind any Swap Agreement if (a) the Parent or the Borrower shall have given prior written
notice to the Administrative Agent of such action, (b) the economic effect of such Swap Agreement
was to increase the Borrowing Base then in effect, the Required Lenders shall have the right to
adjust the Borrowing Base to reflect such termination and (c) the Borrower shall have (after giving
effect to any termination payments associated with termination) unused availability under this
Agreement of not less than 15% of the then current Borrowing Base.

     Section 8.17 Marketing Activities. The Borrower will not, and will not permit any of
the Borrower’s Subsidiaries to, engage in marketing activities for any Hydrocarbons or enter into
any contracts related thereto other than (i) contracts for the sale of Hydrocarbons scheduled or
reasonably estimated to be produced from their proved Oil and Gas Properties during the period of
such contract, (ii) contracts for the sale of Hydrocarbons scheduled or reasonably estimated to be
produced from proved Oil and Gas Properties of third parties during the period of such contract
associated with the Oil and Gas Properties of the Borrower and the Borrower’s Subsidiaries that the
Borrower or one of the Borrower’s Subsidiaries has the right to market pursuant to joint operating
agreements, unitization agreements or other similar contracts that are usual and customary in the
oil and gas business and (iii) other contracts for the purchase and/or sale of Hydrocarbons of
third parties (A) which have generally offsetting provisions (i.e. corresponding pricing mechanics,
delivery dates and points and volumes) such that no “position” is taken and (B) for which
appropriate credit support has been taken to alleviate the material credit risks of the
counterparty thereto.

payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall become
due and payable immediately, without presentment, demand, protest, notice of intent to accelerate,
notice of acceleration or other notice of any kind, all of which are hereby waived by the Borrower
and each Guarantor; and in case of an Event of Default described in Section 10.01(h), Section
10.01(i) or Section 10.01(j), the Commitments shall automatically terminate and the Notes and the
principal of the Loans then outstanding, together with accrued interest thereon and all fees and
the other obligations of the Borrower and the Guarantors accrued hereunder and under the Notes and
the other Loan Documents (including, without limitation, the payment of cash collateral to secure
the LC Exposure as provided in Section 2.08(j)), shall automatically become due and payable,
without presentment, demand, protest or other notice of any kind, all of which are hereby waived by
the Borrower and each Guarantor.

73

 

          (b) In the case of the occurrence of an Event of Default, the Administrative Agent and the
Lenders will have all other rights and remedies available at law and equity.

          (c) All proceeds realized from the liquidation or other disposition of collateral or otherwise
received after maturity of the Notes, whether by acceleration or otherwise, shall be applied:

               (i) first, to payment or reimbursement of that portion of the Indebtedness constituting fees,
expenses and indemnities payable to the Administrative Agent in its capacity as such;

               (ii) second, pro rata to payment or reimbursement of that portion of the Indebtedness

Requirement.

ARTICLE XI

The Agents

     Section 11.01 Appointment; Powers. Each of the Lenders and the Issuing Bank hereby
irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent
to take such actions on its behalf and to exercise such powers as are delegated to the
Administrative Agent by the terms hereof and the other Loan Documents, together with such actions
and powers as are reasonably incidental thereto.

     Section 11.02 Duties and Obligations of Administrative Agent. The Administrative
Agent shall not have any duties or obligations except those expressly set forth in the Loan
Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall
not be subject to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law; rather, such term is used
merely as a matter of market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties), (b) the Administrative Agent shall have no
duty to take any discretionary action or exercise any discretionary powers, except as provided in
Section 11.03, and (c) except as expressly set forth herein, the Administrative Agent shall not
have any duty to disclose, and shall not be liable for the failure to

74

 

disclose, any information relating to the Parent, the Borrower or any of their Subsidiaries
that is communicated to or obtained by the bank serving as Administrative Agent or any of its
Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any
Default unless and until written notice thereof is given to the Administrative Agent by the Parent,
the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire
into (i) any statement, warranty or representation made in or in connection with this Agreement or
any other Loan Document, (ii) the contents of any certificate, report or other document delivered
hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the
performance or observance of any of the covenants, agreements or other terms or conditions set
forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or
genuineness of this Agreement, any other Loan Document or any other agreement, instrument or
document, (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other
than to confirm receipt of items expressly required to be delivered to the Administrative Agent or
as to those conditions precedent expressly required to be to the Administrative Agent’s
satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the
financial or other condition of the Parent, the Borrower and each of their Subsidiaries or any
other obligor or guarantor, or (vii) any failure by the Parent or the Borrower or any other Person
(other than itself) to perform any of its obligations hereunder or under any other Loan Document or
the performance or observance of any covenants, agreements or other terms or conditions set forth
herein or therein. For purposes of determining compliance with the conditions specified in Article
VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with,
each document or other matter required thereunder to be consented to or approved by or acceptable
or satisfactory to a Lender unless the Administrative Agent shall have received written notice from
such Lender prior to the proposed closing date specifying its objection thereto.

     Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no
duty to take any discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby or by the other Loan Documents that the
Administrative Agent is required to exercise in writing as directed by the Required Lenders (or
such other number or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in
failing or refusing to act hereunder or under any other Loan Documents unless it shall (a) receive
written instructions from the Required Lenders or the Lenders, as applicable, (or such other number
or percentage of the Lenders as shall be necessary under the circumstances as provided in Section
12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders
against any and all liability and expenses which may be incurred by it by reason of taking or
continuing to take any such action. The instructions as aforesaid and any action taken or failure
to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a
Default has occurred and is continuing, then the Administrative Agent shall take such action with
respect to such Default as shall be directed by the requisite Lenders in the written instructions
(with indemnities) described in this Section 11.03; 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 as it shall deem advisable in the best interests of the Lenders. In no event, however,
shall the Administrative Agent be required to take any action which exposes the Administrative
Agent to personal liability or which is contrary to this Agreement, the Loan Documents or

75

 

applicable law. If a Default has occurred and is continuing, neither the Syndication Agent
nor the Documentation Agent shall have any obligation to perform any act in respect thereof. The
Administrative Agent shall not be liable for any action taken or not taken by it with the consent
or at the request of the Required Lenders or the Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise
the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or
under any other Loan Document or under any other document or instrument referred to or provided for
herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE,
except for its own gross negligence or willful misconduct.

     Section 11.04 Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely upon, and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon
any statement made to it orally or by telephone and believed by it to be made by the proper Person,
and shall not incur any liability for relying thereon and each of the Parent, the Borrower, the
Lenders and the Issuing Bank hereby waives the right to dispute the Administrative Agent’s record
of such statement, except in the case of gross negligence or willful misconduct by the
Administrative Agent. The Administrative Agent may consult with legal counsel (who may be counsel
for the Parent and/or the Borrower), independent accountants and other experts selected by it, and
shall not be liable for any action taken or not taken by it in accordance with the advice of any
such counsel, accountants or experts. The Administrative Agent may deem and treat the payee of any
Note as the holder thereof for all purposes hereof unless and until a written notice of the
assignment or transfer thereof permitted hereunder shall have been filed with the Administrative
Agent.

     Section 11.05 Subagents. The Administrative Agent may perform any and all its duties
and exercise its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its
duties and exercise its rights and powers through their respective Related Parties. The
exculpatory provisions of the preceding Sections of this Article XI shall apply to any such
sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall
apply to their respective activities in connection with the syndication of the credit facilities
provided for herein as well as activities as Administrative Agent.

     Section 11.06 Resignation or Removal of Administrative Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided in this Section 11.06,
the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the
Borrower, and the Administrative Agent may be removed at any time with or without cause by the
Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right,
in consultation with the Borrower, to appoint a successor. If no successor shall have been so
appointed by the Required Lenders and shall have accepted such appointment within 30 days after the
retiring Agent gives notice of its resignation or removal of the retiring Agent, then the retiring
Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Agent which shall be
a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance
of its appointment as Agent hereunder by a

76

 

successor, such successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder. The fees payable by the Borrower to a successor Agent shall be
the same as those payable to its predecessor unless otherwise agreed between the Borrower and such
successor. After the Agent’s resignation hereunder, the provisions of this Article XI and Section
12.03 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be taken by any of them
while it was acting as Agent.

     Section 11.07 Agents as Lenders. Each bank serving as an Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and may exercise the
same as though it were not an Agent, and such bank and its Affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Parent, the Borrower or any
Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

     Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and
without reliance upon the Administrative Agent, any other Agent or any other Lender and based on
such documents and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and each other Loan Document to which it is a party. Each
Lender also acknowledges that it will, independently and without reliance upon the Administrative
Agent, any other Agent or any other Lender and based on such documents and information as it shall
from time to time deem appropriate, continue to make its own decisions in taking or not taking
action under or based upon this Agreement, any other Loan Document, any related agreement or any
document furnished hereunder or thereunder. The Agents shall not be required to keep themselves
informed as to the performance or observance by the Parent, the Borrower or any of their
Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided
for herein or to inspect the Properties or books of the Parent, the Borrower or any of their
Subsidiaries. Except for notices, reports and other documents and information expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or any Arranger
shall have any duty or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Parent or the Borrower (or any of
their Affiliates) which may come into the possession of such Agent or any of its Affiliates. In
this regard, each Lender acknowledges that Vinson & Elkins LLP is acting in this transaction as
special counsel to the Administrative Agent only, except to the extent otherwise expressly stated
in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal
counsel to the extent that it deems necessary in connection with the Loan Documents and the matters
contemplated therein.

     Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to the Parent, the Borrower or any of their
Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall
then be due and payable as herein expressed or by declaration or otherwise and irrespective of
whether the Administrative Agent shall have made any demand on the Parent or the Borrower) shall be
entitled and empowered, by intervention in such proceeding or otherwise:

77

 

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file
such other documents as may be necessary or advisable in order to have the claims of the Lenders
and the Administrative Agent (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Lenders and the Administrative Agent and their respective agents
and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03)
allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender to make such payments to the
Administrative Agent and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its
agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement,
adjustment or composition affecting the Indebtedness or the rights of any Lender or to authorize
the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

     Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each
Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any collateral
that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender
and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the
Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination
statements, assignments or other documents reasonably requested by the Borrower in connection with
any sale or other disposition of Property to the extent such sale or other disposition is permitted
by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents.

     Section 11.11 The Arrangers, the Syndication Agent and the Documentation Agent. None
of the Arrangers, the Syndication Agent or the Documentation Agent shall have any duties,
responsibilities or liabilities under this Agreement and the other Loan Documents other than their
duties, responsibilities and liabilities in their capacity as Lenders hereunder.

any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any
right, power or privilege, or any abandonment or discontinuance of steps to enforce such right,
power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall
any single or partial exercise of any right, power or privilege under any of the Loan Documents
preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies of the Administrative Agent, any other Agent, the Issuing Bank
and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive
of any rights or remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by the Parent or the Borrower
therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b),
and then such waiver or consent shall be effective only in the specific instance and for the
purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or
issuance of a Letter of Credit shall not be construed as a
waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any
Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

79

 

          (b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any
provision thereof may be waived, amended or modified except pursuant to an agreement or agreements
in writing entered into by the Parent, the Borrower and the Required Lenders or by the Parent, the
Borrower and the Administrative Agent with the consent of the Required Lenders; provided
that no such agreement shall (i) increase the Commitment or the Maximum Credit Amount of any Lender
without the written consent of such Lender, (ii) increase the Borrowing Base without the written
consent of each Lender (other than Defaulting Lenders), decrease or maintain the Borrowing Base
without the consent of the Required Lenders, or modify Section 2.07 in any manner without the

prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any
fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or
reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date

Defaulting Lenders), (vii) release any Guarantor (except as set forth in the Guaranty Agreement),
release any of the collateral (other than as provided in Section 11.10), or reduce the percentage
set forth in Section 8.14(a) to less than 85%, without the written consent of each Lender (other
than Defaulting Lenders), or (viii) change any of the provisions of this Section 12.02(b) or the
definitions of “Required Lenders” or any other provision hereof specifying the number or percentage
of Lenders required to waive, amend or modify any rights hereunder or under any other Loan
Documents or make any determination or grant any consent hereunder or any other Loan Documents,
without the written consent of each Lender (other than Defaulting Lenders); provided
further that no such agreement shall amend, modify or otherwise affect the rights or duties
of the Administrative Agent, any other Agent, or the Issuing Bank hereunder or under any other Loan
Document without the prior written consent of the Administrative Agent, such other Agent or the
Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14
(Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental
schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a
copy thereof to the Lenders.

     Section 12.03 Expenses, Indemnity; Damage Waiver.

          (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the

limitation, all such out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans or Letters of Credit.

          (b) THE PARENT AND THE BORROWER SHALL INDEMNIFY EACH AGENT, EACH ARRANGER, THE ISSUING BANK
AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING
CALLED AN “INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND
ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE REASONABLE
FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST

MATERIALS ON OR AT ANY OF THEIR PROPERTIES, (ix) THE BREACH OR NON-COMPLIANCE BY THE PARENT, THE

          (c) To the extent that the Parent or the Borrower fails to pay any amount required to be paid

as the case may be, such Lender’s Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage, liability or

or the Issuing Bank in its capacity as such.

          (d) To the extent permitted by applicable law, the Parent or the Borrower shall not assert,
and hereby waives, any claim against any Indemnitee, on any theory of liability, for special,
indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out
of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement
or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the
use of the proceeds thereof.

          (e) All amounts due under this Section 12.03 shall be payable not later than five days after
written demand therefor.

     Section 12.04 Successors and Assigns.

          (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) neither the Parent
nor the Borrower may assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender (and any attempted assignment or transfer by the
Parent or the Borrower without such consent shall be null and void) and (ii) no Lender may assign
or otherwise transfer its rights or obligations hereunder except in accordance with this Section
12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns permitted hereby
(including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to
the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the
Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

          (b) (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to
one or more assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans at the time owing to it) with the prior
written consent (such consent not to be unreasonably withheld) of:

                    (A) the Borrower; provided that no consent of the Borrower shall be required if such
assignment is to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default
has occurred and is continuing, is to any other assignee; and

83

 

                    (B) the Administrative Agent; provided that no consent of the Administrative Agent
shall be required for an assignment to an assignee that is a Lender immediately prior to giving
effect to such assignment.

               (ii) Assignments shall be subject to the following additional conditions:

                    (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an
assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount
of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as
of the date the Assignment and Assumption with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the
Administrative Agent otherwise consent; provided that no such consent of the Borrower shall
be required if an Event of Default has occurred and is continuing;

                    (B) each partial assignment shall be made as an assignment of a proportionate part of all the
assigning Lender’s rights and obligations under this Agreement;

                    (C) the parties to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Assumption, together with a processing and recordation fee of $3,500; and

                    (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an
Administrative Questionnaire.

               (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after
the effective date specified in each Assignment and Assumption the assignee thereunder shall be a
party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have
the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder
shall, to the extent of the interest assigned by such Assignment and Assumption, be released from
its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all
of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Section 5.01, Section 5.02,
Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of
this Agreement as a sale by such Lender of a participation in such rights and obligations in
accordance with Section 12.04(c).

               (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall
maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the Maximum Credit
Amount of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to
the terms hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register
shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any
reasonable time and from time to time upon reasonable prior notice. In connection with any changes
to the Register, if necessary, the
Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised
Annex I to the Borrower, the Issuing Bank and each Lender.

84

 

               (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
shall already be a Lender hereunder), the processing and recordation fee referred to in Section
12.04(a)(ii)(C) and any written consent to such assignment required by Section 12.04(a)(i), the
Administrative Agent shall accept such Assignment and Assumption and record the information
contained therein in the Register. No assignment shall be effective for purposes of this Agreement
unless it has been recorded in the Register as provided in this Section 12.04(b).

          (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the
Issuing Bank, sell participations to one or more banks or other entities (a “Participant”)
in all or a portion of such Lender’s rights and obligations under this Agreement (including all or
a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s
obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and (C) the
Borrower, the Administrative Agent, the Issuing Bank 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. Any agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve
any amendment, modification or waiver of any provision of this Agreement; provided that
such agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the proviso to Section
12.02 that affects such Participant. In addition such agreement must provide that the Participant
be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees
that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section
5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant
to Section 12.04(a). To the extent permitted by law, each Participant also shall be entitled to
the benefits of Section 12.08 as though it were a Lender; provided such Participant agrees
to be subject to Section 4.01(c) as though it were a Lender.

               (ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or
Section 5.03 than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to such Participant is
made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it
were a Lender shall not be entitled to the benefits of Section 5.03 unless the Borrower is notified
of the participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 5.03(d) as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including, without
limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank, and this
Section 12.04(d) shall not apply to any such pledge or assignment of a security interest;
provided that no such pledge or assignment of a security interest shall release a
Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto.

85

 

     Section 12.05 Survival; Revival; Reinstatement.

          (a) All covenants, agreements, representations and warranties made by the Parent and the
Borrower herein and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon
by the other parties hereto and shall survive the execution and delivery of this Agreement and the
making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the Administrative Agent, any other
Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and shall continue in full
force and effect as long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is
outstanding and so long as the Commitments have not expired or terminated. The provisions of
Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and Article XI shall survive and remain
in full force and effect regardless of the consummation of the transactions contemplated hereby,
the repayment of the Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement, any other Loan Document or any provision hereof
or thereof.

          (b) To the extent that any payments on the Indebtedness or proceeds of any collateral are
subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be
repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law,
common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived
and continue as if such payment or proceeds had not been received and the Administrative Agent’s
and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and
each Loan Document shall continue in full force and effect. In such event, each Loan Document
shall be automatically reinstated and the Parent and the Borrower shall, and shall cause each of
its Subsidiaries to, take such action as may be reasonably requested by the Administrative Agent
and the Lenders to effect such reinstatement.

     Section 12.06 Counterparts; Integration; Effectiveness.

          (a) This Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of which when taken
together shall constitute a single contract.

          (b) This Agreement, the other Loan Documents and any separate letter agreements with respect
to fees payable to the Administrative Agent constitute the entire contract among the parties
relating to the subject matter hereof and thereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN
THE PARTIES.

86

 

          (c) Except as provided in Section 6.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent shall have
received counterparts hereof which, when taken together, bear the signatures of each of the other
parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart of a signature
page of this Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

     Section 12.07 Severability. Any provision of this Agreement or any other Loan
Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining provisions hereof or
thereof; and the invalidity of a particular provision in a particular jurisdiction shall not
invalidate such provision in any other jurisdiction.

     Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time
to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general
or special, time or demand, provisional or final) at any time held and other obligations (of
whatsoever kind, including, without limitations obligations under Swap Agreements) at any time
owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any
Subsidiary against any of and all the obligations of the Borrower or any Subsidiary owed to such
Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of
whether or not such Lender shall have made any demand under this Agreement or any other Loan
Document and although such obligations may be unmatured. The rights of each Lender under this
Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which
such Lender or its Affiliates may have.

     Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

          (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF TEXAS EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER
TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE
STATE WHERE SUCH LENDER IS LOCATED. CHAPTER 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN
REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT
OR THE NOTES.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE
COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS,
AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH

87

 

PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS
PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY
HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING
OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO
JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER
ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

          (c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED
MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS
SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME
EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR
ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL
PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION.

          (d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY

SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO,
ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR

THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS
BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED
HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS
SECTION 12.09.

     Section 12.10 Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and shall not affect
the construction of, or be taken into consideration in interpreting, this Agreement.

     Section 12.11 Confidentiality. Each of the Administrative Agent, the Issuing Bank and
the Lenders agrees to maintain the confidentiality of the Information (as defined below), except
that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and

88

 

agents, including accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the extent requested by
any regulatory authority, (c) to the extent required by applicable laws or regulations or by any
subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan
Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan
Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or
the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing
provisions substantially the same as those of this Section 12.11, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap
Agreement relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h)
to the extent such Information (i) becomes publicly available other than as a result of a breach of
this Section 12.11 or (ii) becomes available to the Administrative Agent, the Issuing Bank or any
Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this
Section 12.11, “Information” means all information received from the Parent, the Borrower
or any Subsidiary relating to the Parent, the Borrower or any Subsidiary and their businesses,
other than any such information that is available to the Administrative Agent, the Issuing Bank or
any Lender on a nonconfidential basis prior to disclosure by the Parent, the Borrower or a
Subsidiary; provided that, in the case of information received from the Parent, the
Borrower or any Subsidiary after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section 12.11 shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own confidential
information. Notwithstanding anything herein to the contrary, “Information” shall not include, and
the Parent, the Parent’s Subsidiaries, the Borrower, the Borrower’s Subsidiaries, the
Administrative Agent, each Lender and the respective Affiliates of each of the foregoing (and the
respective partners, directors, officers, employees, agents, advisors and other representatives of
the aforementioned Persons), and any other party, may disclose to any and all Persons, without
limitation of any kind (a) any information with respect to the U.S. federal and state income tax
treatment of the transactions contemplated hereby and any facts that may be relevant to
understanding the U.S. federal or state income tax treatment of such transactions (“tax
structure”), which facts shall not include for this purpose the names of the parties or any
other person named herein, or information that would permit identification of the parties or such
other persons, or any pricing terms or other nonpublic business or financial information that is
unrelated to such tax treatment or tax structure, and (b) all materials of any kind (including
opinions or other tax analyses) that are provided to the Parent, the Borrower, the Administrative
Agent or such Lender relating to such tax treatment or tax structure.

     Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto
that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the
transactions contemplated hereby would be usurious as to any Lender under laws applicable to it
(including the laws of the United States of America and the State of Texas or any other
jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other
provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as security for the
Notes, it is

89

 

agreed as follows: (i) the aggregate of all consideration which constitutes interest under
law applicable to any Lender that is contracted for, taken, reserved, charged or received by such
Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such applicable law, and any
excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on
the principal amount of the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the
Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an
election of the holder thereof resulting from any Event of Default under this Agreement or
otherwise, or in the event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to any Lender may never include more than the maximum
amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement
or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of
the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been
or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or
agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall,
to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and
spread throughout the stated term of the Loans evidenced by the Notes until payment in full so that
the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount
allowed by such applicable law. If at any time and from time to time (i) the amount of interest
payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such
Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation
period the amount of interest otherwise payable to such Lender would be less than the amount of
interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then
the amount of interest payable to such Lender in respect of such subsequent interest computation
period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the
total amount of interest payable to such Lender shall equal the total amount of interest which
would have been payable to such Lender if the total amount of interest had been computed without
giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code is
relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender
elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time
to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Parent’s or the
Borrower’s obligations hereunder.

     Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES
THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS
CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT
IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE
TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL
COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS; AND

90

 

THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND
RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND
COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF
THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE
OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

     Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security
Instruments and of the provisions of this Agreement relating to any collateral securing the
Indebtedness shall also extend to and be available to those Lenders or their Affiliates which are
counterparties to any Swap Agreement with the Borrower or any of its Subsidiaries on a pro rata
basis in respect of any obligations of the Borrower or any of its Subsidiaries which arise under
any such Swap Agreement while such Person or its Affiliate is a Lender, but only while such Person
or its Affiliate is a Lender, including any Swap Agreements between such Persons in existence prior
to the date hereof. No Lender or any Affiliate of a Lender shall have any voting rights under any
Loan Document as a result of the existence of obligations owed to it under any such Swap
Agreements.

     Section 12.15 No Third Party Beneficiaries. This Agreement, the other Loan Documents,
and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or
extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person
(including, without limitation, any Subsidiary of the Borrower, any obligor, contractor,
subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges
hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the
Issuing Bank or any Lender for any reason whatsoever. There are no third party beneficiaries.

     Section 12.16 Acknowledgements. Each of the Parent and the Borrower hereby
acknowledges that:

          (a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement and the other Loan Documents;

          (b) neither the Administrative Agent nor any Lender has a fiduciary relationship with or duty
to the Parent or the Borrower or any of their Subsidiaries arising out of or in connection with
this Agreement or any other Loan Document, and the relationship between the Administrative Agent
and the Lenders, on the one hand, and the Parent and the Borrower, on the other hand, in connection
herewith and therewith is solely that of debtor and creditor;

          (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by
virtue of the transactions contemplated hereby among the Lenders or among the Parent, the Borrower
and the Lenders.

91

 

     Section 12.17 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information
that identifies the Borrower, which information includes the name and address of the Borrower and
other information that will allow such Lender to identify the Borrower in accordance with the Act.
