ARTICLE II.

THE COMMITMENTS AND BORROWINGS

     2.01 Term Loans. Subject to the terms and conditions set forth herein, each Lender
agrees to make a loan to the Borrower on the Closing Date in an aggregate principal amount equal to
such Lender’s Commitment. No amounts paid or prepaid with respect to the Loans may be reborrowed.

     2.02 Loans and Borrowings.

     (a) 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 of the Lenders are several and no Lender shall be responsible
for any other Lender’s failure to make Loans as required.

     (b) The initial Borrowing shall be comprised entirely of ABR Loans.

     (c) 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 $100,000 and not less than $1,000,000. 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 four (4) Eurodollar Borrowings outstanding. Each Lender at its option
may make any Eurodollar Borrowing by causing any domestic or foreign branch or Affiliate of such
Lender to make such Borrowing; 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.

23

 

     (d) 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.

     2.03 Requests for Borrowings. To request the initial Borrowing, the Borrower shall
notify the Administrative Agent of such request by telephone not later than 11:00 a.m. on the date
of the proposed Borrowing. 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 a form approved by the Administrative Agent and signed by the Borrower. Such
telephonic and written Borrowing Request shall specify the following information in compliance with
Section 2.02:

     (i) the aggregate amount of the requested Borrowing;

     (ii) the date of such Borrowing, which shall be a Business Day; and

     (iii) the location and number of the Borrower’ account to which funds are to be
disbursed, which shall comply with the requirements of Section 2.06.

Promptly following receipt of the Borrowing Request in accordance with this Section, 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.

     2.04  [Reserved].

     2.05  [Reserved].

     2.06 Funding of Borrowings.

     (a) Each Lender shall make the Loan to be made by it hereunder on the Closing Date by wire
transfer of immediately available funds by 12:00 noon 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 a deposit account of the Borrower designated by the Borrower in the Borrowing
Request.

     (b) Unless the Administrative Agent shall have received notice from a Lender prior to the
proposed date of such 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 the proposed date therefor in accordance with paragraph (a) of
this Section 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

24

 

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.

     2.07 Interest Elections.

     (a) Following the initial Borrowing, the Borrower may elect to convert any Borrowing to a
different Type or to continue any Borrowing and, in the case of a Eurodollar Borrowing, may elect
Interest Periods therefor, all as provided in this Section. 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) To make an election pursuant to this Section, the Borrower shall notify the Administrative
Agent of such election by telephone (a) in the case of a Eurodollar Borrowing, not later than by
11:00 a.m., three Business Days before the effective date of the proposed conversion or
continuation or (b) in the case of an ABR Borrowing, not later than 11:00 a.m. on the effective
date of the proposed conversion or continuation. 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 a form approved by the
Administrative Agent and signed by the Borrower.

     (c) Each telephonic and written Interest Election Request shall specify the following
information:

     (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 clauses (iii) and (iv) below 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.

25

 

     (d) 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) 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 has occurred and is continuing and the Administrative Agent, at the request of the Required
Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no
outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless
repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto.

     2.08 Termination or Reduction of Commitments. The Commitments of each Lender shall
terminate immediately following the making of the Loans by such Lender on the Closing Date pursuant
to Section 2.01.

     2.09 Repayment of Loans.

     (a) The Borrower hereby unconditionally promises to repay to the Administrative Agent for the
account of each Lender the outstanding principal of the Loans until repaid in full in accordance
with the following amortization schedule:

     (i) an amount equal to $500,000.00 shall be due and payable on the last day of each
calendar quarter commencing with the calendar quarter ending June 30, 2007, to and including
the calendar quarter ending December 31, 2011; and

     (ii) the then unpaid principal amount of each Loan shall be due and payable on the
Maturity Date.

     (b) Each Lender shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such
Lender, including the amounts of principal and interest payable and paid to such Lender from time
to time hereunder.

     (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount
of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable from the Borrower
to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder for the account of the Lenders and each Lender’s share thereof.

     (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this
Section shall be prima facie evidence of the existence and amounts of the
obligations recorded therein; provided that the failure of any Lender or the Administrative
Agent to maintain such accounts or any error therein shall not in any manner affect the obligation
of the Borrower to repay the Loans in accordance with the terms of this Agreement.

26

 

     (e) Any Lender or Participant may request that the Loan made by it be evidenced by a
promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender or
Participant a promissory note payable to the order of such Lender or Participant (or, if requested
by such Lender or Participant, to such Lender or Participant and its registered assigns) and in the
form attached hereto as Exhibit A; provided that any promissory note issued to
evidence any Lender’s Loans shall be in a stated amount equal to such Lender’s Applicable
Percentage of the Facility Amount. Thereafter, the Loans evidenced by such promissory note and
interest thereon shall at all times (including after assignment pursuant to Section 10.06) be
represented by one or more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its registered
assigns).

     (f) Each payment made to the Administrative Agent in respect of a Borrowing shall be applied
ratably to the Loans included in the repaid Borrowing. Repayments shall be accompanied by accrued
interest to the extent required by Section 2.13.

     2.10 Optional Prepayment of Loans.

     (a) The Borrower shall have the right at any time and from time to time to prepay any
Borrowing in whole and or in part, subject to prior notice in accordance with paragraph (b) of this
Section, provided that the Borrower shall also pay the applicable Prepayment Premium with respect
to any such optional prepayment.

     (b) 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
11:00 a.m. three Business Days prior to the date of prepayment, or (ii) in the case of prepayment
of an ABR Borrowing, not later than 11:00 a.m. on 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 aggregate amount that is an integral multiple of
$500,000 and not less than $500,000. 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 2.13 and any Prepayment Premium to the extent required by clause
(a) above.

     2.11 Mandatory Prepayment of Loans.

     (a) Not later than the next Business Day after it receives Net Cash Proceeds from any
Disposition in excess of $25,000,000 in the aggregate in any period of twelve consecutive months,
or any casualty event or loss, of Borrowing Base Properties pursuant to clause (c) of Section 7.05,
the Borrower shall, or shall cause one or more of its Restricted Subsidiaries to, apply 100% of the
Net Cash Proceeds received in respect of such Disposition or casualty event or loss to prepay
outstanding Loans in accordance with Section 2.11(d) hereof, together with any applicable
Prepayment Premium; provided that such Net Cash Proceeds shall only be required to be
applied as provided above to the extent (if any) that any such Net Cash Proceeds remain after the
Borrower or any Restricted Subsidiary shall have made (x) any mandatory prepayments of

27

 

any credit extension required by the First Lien Facility and (y) any additional prepayment of
any credit extension then outstanding under the First Lien Facility as the Borrower shall elect
provided that concurrently with any such additional prepayment the Borrower shall permanently
reduce the aggregate commitment amount under the First Lien Facility by an equivalent amount;
further provided, however, that, if (1) the Borrower shall deliver a
certificate of a Responsible Officer to the Administrative Agent not later than concurrently with
the consummation of such Disposition or settlement of such casualty event or loss setting forth the
Borrower’s intent to reinvest such Net Cash Proceeds in property of a kind then used or usable in
the business of the Borrower and its Restricted Subsidiaries within 90 days of receipt of such Net
Cash Proceeds, provided, that if the Borrower has signed a purchase and sale agreement to
acquire such property within such 90 day period, then it shall have an additional 90 days in which
to consummate such acquisition, and (2) no Default shall have occurred and shall be continuing at
the time of such certificate or at the proposed time of the application of such Net Cash Proceeds,
then such Net Cash Proceeds shall not be required to be applied in accordance with the foregoing
provisions of this Section 2.11(a) unless and until such 90-day period has elapsed and all or any
portion of such Net Cash Proceeds shall not have been so reinvested, at which time all or any
remaining portion of such Net Cash Proceeds shall immediately be applied in accordance with this
Section 2.11(a) and Section 2.11(d).

     (b) In the event and on each occasion that an Equity Issuance occurs, the Borrower shall, or
shall cause one or more of its Restricted Subsidiaries to, concurrently with (and in any event not
later than the third Business Day next following) the receipt by the Borrower or any of its
Restricted Subsidiaries of the Net Cash Proceeds of such Equity Issuance, apply an amount equal to
50% of the Net Cash Proceeds therefrom to prepay outstanding Loans in accordance with Section
2.11(d), together with any applicable Prepayment Premium; provided that such Net Cash
Proceeds shall only be required to be applied to the extent (if any) that such Net Cash Proceeds
remain after making (i) any mandatory prepayments of any credit extension required by the First
Lien Facility and (ii) any additional prepayment of any credit extension then outstanding under the
First Lien Facility as the Borrower shall elect provided that concurrently with any such additional
prepayment the Borrower shall permanently reduce the aggregate commitment amount under the First
Lien Facility by an equivalent amount.

     (c) In the event that the Borrower or any Guarantor or any of their Subsidiaries shall receive
Net Cash Proceeds from the issuance or incurrence of Indebtedness for borrowed money by the
Borrower or any Guarantor or any of its or their Restricted Subsidiaries (other than any cash
proceeds from the issuance of Indebtedness permitted pursuant to Section 7.03 (it being
acknowledged that any such issuance or incurrence of Indebtedness for borrowed money not otherwise
permitted under Section 7.03 shall require the approval of the Required Lenders)), the Borrower
shall, concurrently with (and in any event not later than the third Business Day next following)
the receipt of such Net Cash Proceeds by such Person, apply an amount equal to 100% of such Net
Cash Proceeds therefrom to prepay outstanding Loans in accordance with Section 2.11(d), together
with any applicable Prepayment Premium; provided that such Net Cash Proceeds shall only be
required to be applied to the extent (if any) that such Net Cash Proceeds remain after making (i)
any mandatory prepayments of any credit extension required by the First Lien Facility and (ii) any
additional prepayment of any credit extension then outstanding under the First Lien Facility as the
Borrower shall elect provided that concurrently with any such

28

 

additional prepayment the Borrower shall permanently reduce the aggregate commitment amount
under the First Lien Facility by an equivalent amount.

     (d) Each prepayment of Borrowings pursuant to this Section 2.11 shall be applied ratably to
the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 2.11 shall be
accompanied by accrued interest to the extent required by Section 2.13 and, any applicable
Prepayment Premium to the extent required by such clauses (a), (b) or (c), as applicable.

     (e) The Borrower shall deliver to the Administrative Agent, at the time of each prepayment
required under this Section 2.11, (i) a certificate signed by a Responsible Officer of the Borrower
setting forth in reasonable detail the calculation of the amount of such prepayment and (ii) to the
extent practicable, at least three days prior written notice of such prepayment. Each notice of
prepayment shall specify the prepayment date, the Type of each Borrowing being prepaid and the
principal amount of each Loan (or portion thereof) to be prepaid.

     2.12 Fees.

     (a) As required under the Fee Letter, 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.

     (b) All fees payable hereunder shall be paid on the dates due, in immediately available funds,
to the Administrative Agent for distribution to the Lenders. Fees paid shall not be refundable
under any circumstances.

     2.13 Interest.

     (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate
plus the Applicable Rate.

     (b) 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 Rate.

     (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or
other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity,
upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus
the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section
or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in
paragraph (a) of this Section.

     (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date
for such Loan and on the Maturity Date; provided that (i) interest accrued pursuant to
paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or
prepayment of any Loan, 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

29

 

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) All interest hereunder shall be computed on the basis of a year of 360 days, 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.

     2.14 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, as applicable, for such Interest Period; or

     (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or
the 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, 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 shall be deemed
to be a request for an ABR Borrowing).

     2.15 Increased Costs.

     (a) 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
increase the cost to such Lender or to reduce the amount of any sum received or receivable by such
Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such
Lender, as the case may be, such additional amount or amounts as will compensate such Lender for
such additional costs incurred or reduction suffered.

30

 

     (b) If any Lender 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 capital or on the capital of
such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such
Lender to a level below that which such Lender or such Lender’s holding company could have achieved
but for such Change in Law (taking into consideration such Lender’s policies and the policies of
such Lender’s holding company with respect to capital adequacy), then from time to time the
Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender
or such Lender’s holding company for any such reduction suffered.

     (c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such
Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this
Section 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.

     (d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section
shall not constitute a waiver of such Lender’s right to demand such compensation; provided
that the Borrower shall not be required to compensate a Lender pursuant to this Section for any
increased costs or reductions incurred more than 270 days prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of
such Lender’s intention to claim compensation therefor; provided further that, if
the Change in Law giving rise to such increased costs or reductions is retroactive, then the
270-day period referred to above shall be extended to include the period of retroactive effect
thereof.

     2.16 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 other than on the last
day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto
(regardless of whether such notice may be revoked under 2.10(b) and is revoked in accordance
therewith), 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 2.19, 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 shall be delivered to

31

 

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.

     2.17 Taxes.

     (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be
made free and clear of and without deduction for any Indemnified Taxes or Other Taxes;
provided that if the Borrower 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) the Administrative Agent or any Lender (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 shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

     (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority
in accordance with applicable law.

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

     (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the
Borrower 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) 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.

     (f) If the Administrative Agent or a 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 2.17, it
shall pay over such refund to the Borrower (but only to the extent of indemnity

32

 

payments made, or additional amounts paid, by the Borrower under this Section 2.17 with
respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses
of the Administrative Agent or such Lender 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 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 Lender in the event the Administrative Agent or such
Lender is required to repay such refund to such Governmental Authority. This Section shall not be
construed to require the Administrative Agent or any Lender to make available its tax returns (or
any other information relating to its taxes which it deems confidential) to the Borrower or any
other Person.

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

     (a) The Borrower shall make each payment required to be made by it hereunder (whether of
principal, interest or of amounts payable under 2.15, 2.16 or 2.17, or otherwise) prior to 12:00
noon on the date when due, in immediately available funds, without set-off or counterclaim. 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 office for
payment specified on Schedule 10.02 (or such other office as may be specified in accordance
with Section 10.02(c)), and except that payments pursuant to 2.15, 2.16, 2.17 and Section 10.04
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.

     (b) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall
be applied first to any interest or fees then due and owing to the extent thereof and then to the
repayment of principal.

     (c) 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 resulting in such
Lender receiving payment of a greater proportion of the aggregate amount of its Loans 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 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; 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 paragraph shall not be construed to apply to any payment made by the
Borrower pursuant to and in accordance with the express terms of this

33

 

Agreement or any payment obtained by a Lender as consideration for the assignment of or sale
of a participation in any of its Loans to any assignee or participant, other than to the Borrower
or any Restricted Subsidiary or Affiliate thereof (as to which the provisions of this paragraph
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.

     (d) 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
hereunder that the Borrower will not make such payment, the Administrative Agent may assume that
the Borrower have made such payment on such date in accordance herewith and may, in reliance upon
such assumption, distribute to the Lenders, the amount due. In such event, if the Borrower have
not in fact made such payment, then each of the Lenders severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such Lender 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.

     (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section
2.06(b), 2.17(d) or 10.04(c), 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 Lender to satisfy such Lender’s obligations under such Sections until all
such unsatisfied obligations are fully paid.

     2.19 Mitigation Obligations; Replacement of Lenders.

     (a) If any Lender requests compensation under Section 2.15, 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 2.17, then such Lender shall use reasonable efforts to designate a different
lending office for funding or booking its Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender,
such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section
2.15 or 2.17, 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) If any Lender requests compensation under Section 2.15, 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 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, 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 10.06, all its interests, rights and obligations under
this Agreement to an assignee that shall assume such

34

 

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, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans, 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 (iii) in the case of any such assignment resulting from a claim for
compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such
assignment will result in a reduction in such compensation or payments. A Lender shall not be
required to make any such assignment and delegation if, prior thereto, as a result of a waiver by
such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and
delegation cease to apply.

     (c) If in connection with any proposed amendment, modification, termination, waiver or consent
with respect to any of the provisions of this Agreement or any other Loan Document as contemplated
by Section 10.01, the consent of Required Lenders shall have been obtained but the consent of one
or more of such other Lenders (each a “Non-Consenting Lender”) whose consent is required
has not been obtained or if any Lender is a Defaulting Lender; then, the Borrower may elect to
replace such Non-Consenting Lender or Defaulting Lender, as the case may be, as a Lender party to
this Agreement in accordance with and subject to the restrictions contained in, and consents
required by Section 10.06; provided that such Lender shall have received payment of an
amount equal to the outstanding principal of its Loans, 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). A
Lender shall not be required to make any such assignment and delegation if, prior thereto, as a
result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require
such assignment and delegation cease to apply or, in the case of a Defaulting Lender, such Lender
is no longer a Defaulting Lender.

reasonably be expected to have a Material Adverse Effect.

     5.02 Authorization; No Contravention. The execution, delivery and performance by each
Loan Party of each Loan Document to which such Person is party, have been duly authorized by all
necessary corporate or other organizational action, and do not and will not (a) contravene the

contravention of, or the creation of any Lien under, or require any payment to be made under (i)
any Contractual Obligation to which such Person is a party or affecting such Person or the
properties of such Person or any of its Subsidiaries or (ii) any order, injunction, writ or decree
of any Governmental Authority or any arbitral award to which such Person or its property is
subject; or (c) violate any Law. Each Loan Party and each Subsidiary

thereof is in compliance with all Contractual Obligations referred to in clause (b)(i), except to the extent
that failure to do so could not reasonably be expected to have a Material Adverse Effect.

     5.03 Governmental Authorization; Other Consents. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any Governmental Authority or any
other Person is necessary or required in connection with the execution, delivery or performance by,
or enforcement against, any Loan Party of this Agreement or any other Loan Document.

     5.04 Binding Effect. This Agreement has been, and each other Loan Document, when
delivered hereunder, will have been, duly executed and delivered by each Loan Party that is party
thereto. This Agreement constitutes, and each other Loan Document when so delivered will

subject to general principles of equity, regardless of whether considered in a proceeding in law or
in equity.

     5.05 Financial Statements; No Material Adverse Effect.

     (a) The Initial Financial Statements (i) were prepared in accordance with GAAP consistently
applied throughout the period covered thereby, except as otherwise expressly noted therein, and
(ii) fairly present the financial condition of the Borrower and its Subsidiaries as of the date
thereof and their results of operations for the period covered thereby (subject, in the case of
clauses (i) and (ii), to the absence of footnotes and to normal year-end audit adjustments), and
(iii) show all material indebtedness and other liabilities, direct or contingent, of the Borrower
and its Subsidiaries as of the date thereof, including liabilities for taxes, material commitments
and Indebtedness.

     (b) Since the date of the Initial Financial Statements, there has been no event or
circumstance, either individually or in the aggregate, that has had or could reasonably be expected
to have a Material Adverse Effect.

     5.06 Litigation. There are no actions, suits, proceedings, claims or disputes pending
or, to the knowledge of the Borrower after due and diligent investigation, threatened or
contemplated, at law, in equity, in arbitration or before any Governmental Authority, by or against
the Borrower or any of its Restricted Subsidiaries or against any of their properties or revenues
that (a) purport to affect or pertain to this Agreement or any other Loan Document, or any of the
transactions contemplated hereby, or (b) either individually or in the aggregate, if determined
adversely, could reasonably be expected to have a Material Adverse Effect.

     5.07 No Default. Neither the Borrower nor any Restricted Subsidiary is in default
under or with respect to any Contractual Obligation that could, either individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. No Default has occurred and

Agreement or any other Loan Document.

40

 

     5.08 Ownership of Property; Liens. Each of the Borrower and each Restricted
Subsidiary has good record and marketable title in fee simple to, or valid leasehold interests in,
all real property necessary or used in the ordinary conduct of its business, except for such
defects in title as could not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. The property of the Borrower and its Restricted Subsidiaries is subject
to no Liens, other than Liens permitted under Section 7.01.

     5.09 Environmental Compliance. The Borrower and its Restricted Subsidiaries conduct
in the ordinary course of business a review of the effect of existing Environmental Laws and claims
alleging potential liability or responsibility for violation of any Environmental Law on their
respective businesses, operations and properties, and as a result thereof the Borrower has
reasonably concluded that such Environmental Laws and claims could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

     5.10 Insurance. The properties of the Borrower and its Restricted Subsidiaries are
insured with financially sound and reputable insurance companies not Affiliates of the Borrower, in
such amounts (after giving effect to any self-insurance compatible with the following standards),

similar businesses and owning similar properties in localities where the Borrower or the applicable
Restricted Subsidiary operates.

     5.11 Taxes. The Borrower and its Subsidiaries have filed all Federal, state and other
material tax returns and reports required to be filed, and have paid all Federal, state and other
material taxes, assessments, fees and other governmental charges levied or imposed upon them or
their properties, income or assets otherwise due and payable, except those which are being
contested in good faith by appropriate proceedings diligently conducted and for which adequate
reserves have been provided in accordance with GAAP. There is no proposed tax assessment against
the Borrower or any Subsidiary that would, if made and not timely paid, have a Material Adverse
Effect. Neither any Loan Party nor any Restricted Subsidiary thereof is party to any tax sharing
agreement.

     5.12 ERISA Compliance.

     (a) Each Plan is in compliance in all material respects with the applicable provisions of
ERISA, the Code and other Federal or state Laws. Each Plan that is intended to qualify under
Section 401(a) of the Code has received a favorable determination letter from the IRS or an
application for such a letter is currently being processed by the IRS with respect thereto and, to
the best knowledge of the Borrower, nothing has occurred which would prevent, or cause the loss of,
such qualification. The Borrower and each ERISA Affiliate have made all required contributions to
each Plan subject to Section 412 of the Code, and no application for a funding waiver or an
extension of any amortization period pursuant to Section 412 of the Code has been made with respect
to any Plan.

     (b) There are no pending or, to the best knowledge of the Borrower, threatened claims, actions
or lawsuits, or action by any Governmental Authority, with respect to any Plan that could
reasonably be expected to have a Material Adverse Effect. There has been no

41

 

prohibited transaction or violation of the fiduciary responsibility rules with respect to any
Plan that has resulted or could reasonably be expected to result in a Material Adverse Effect.

     (c) (i) No ERISA Event has occurred or is reasonably expected to occur; (ii) no Pension Plan
has any Unfunded Pension Liability; (iii) neither the Borrower nor any ERISA Affiliate has
incurred, or reasonably expects to incur, any liability under Title IV of ERISA with respect to any
Pension Plan (other than premiums due and not delinquent under Section 4007 of ERISA); (iv) neither
the Borrower nor any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
(and no event has occurred which, with the giving of notice under Section 4219 of ERISA, would
result in such liability) under Sections 4201 or 4243 of ERISA with respect to a Multiemployer
Plan; and (v) neither the Borrower nor any ERISA Affiliate has engaged in a transaction that could
be subject to Sections 4069 or 4212(c) of ERISA.

     5.13 Subsidiaries; Equity Interests. As of the Closing Date, the Borrower has no
Subsidiaries other than those specifically disclosed in Part (a) of Schedule 5.13, and all
of the outstanding Equity Interests in such Subsidiaries have been validly issued, are fully paid
and nonassessable (except for such Equity Interests consisting of partnership interests and
membership interests) and are owned by a Loan Party as specified, and in the amounts specified, on
Part (a) of Schedule 5.13, free and clear of all Liens (except for Liens created by the
Loan Documents and First Lien Loan Documents). The Borrower has no Equity Interests in any other
corporation or entity other than those specifically disclosed in Part (b) of Schedule 5.13.
After giving effect to the Transactions, and prior to the IPO Date, a majority of the outstanding
Equity Interests in the Borrower are owned by the Control Group.

     5.14 Margin Regulations; Investment Company Act.

     (a) The Borrower is not engaged and will not 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.

registered patents, trademarks, trade names and service marks, the non-preservation of which could
reasonably be expected to have a Material Adverse Effect.

     6.06 Maintenance of Properties. (a) Maintain, preserve and protect the Borrowing Base
Properties and all of its other material properties and equipment necessary in the operation of the

accountants, all at the expense and risk of the Administrative Agent or Lenders, as applicable, and
at such reasonable times during normal business hours and as often as may be reasonably desired,

it owns Borrowing Base Properties and such Mortgage is necessary to cause the Borrower to comply
with Section 6.16(c)) or other security agreement in form and substance acceptable to
Administrative Agent (to the extent it owns personal property and such security agreement is
necessary to cause the Borrower to comply with Section 6.16(c)) and promptly take such actions to

Administrative Agent and promptly take such actions to create and perfect Liens on such assets to
secure the Obligations as the Administrative Agent or the Required Lenders shall reasonably request
subject at all times to the Intercreditor Agreement. Any Restricted Subsidiary formed or acquired
on or after the Closing Date shall be a Wholly Owned Subsidiary.

reasonably be expected to have a Material Adverse Effect.

     6.14 Delivery of Title Opinions. As and when requested by the Administrative Agent,
deliver to the Administrative Agent such reports, opinions of counsel (which opinions are not
required to be addressed to the Administrative Agent) and other evidence of title as the

and its Restricted Subsidiaries to not less than eighty percent (80%) of the Engineered Value of
the Borrowing Base Properties that are subject to a Mortgage and at least the working interest and
net revenue interest in such oil and gas properties set forth in the most recent Engineering Report
and (ii) the validity, perfection and priority of the Liens created by the Mortgages and Security
Instruments and such other matters regarding such Mortgages as Administrative Agent shall
reasonably request (provided that this clause (ii) shall not be construed to require the Borrower
to deliver, or cause to be delivered, any opinion of counsel as to the priority of any Liens).

Closing Date, the Borrower shall, or shall cause COG LP to, deliver the Administrative Agent, in

Loan Documents, certificates, resolutions, opinions or other documents described in clauses (iii)
or (vii) of Section 4.01(a).

49

 

     6.16 Further Assurances.

deeds, conveyances, security agreements, mortgages, assignments, estoppel certificates,
letter-in-lieu, financing statements and continuations thereof, termination statements, notices of

actions and execute and deliver such documents and instruments as Administrative Agent shall
reasonably require to ensure that the Administrative Agent shall, at all times, have received
currently effective, duly executed Mortgages as may be necessary or, in the reasonable opinion of
Administrative Agent, desirable to effectively create a valid, perfected and, subject to the
Intercreditor Agreement, second priority Lien against Borrowing Base Properties representing at
least 80% of the Engineered Value of all proved Borrowing Base Properties included in the most
recent Engineering Report provided to the Lenders, and the Borrower and its Restricted Subsidiaries
shall, at the request of Administrative Agent, execute and deliver such additional Mortgages as may
be necessary or, in the reasonable opinion of Administrative Agent, desirable to effectively create
a valid, perfected and, subject to the Intercreditor Agreement, second priority Lien, subject only

holders or beneficiary or beneficiaries) to cause, with the giving of notice if required, such
Indebtedness to be demanded or to become due or to be repurchased, prepaid, defeased or redeemed

Party or any other Affiliate of the Borrower contests in any manner the validity or enforceability

commitments and obligation shall be terminated;

     (b) declare the unpaid principal amount of all outstanding Loans, all interest accrued and
unpaid thereon, and all other amounts owing or payable hereunder or under any other Loan Document
to be immediately due and payable, without presentment, demand, protest or other notice of any
kind, all of which are hereby expressly waived by the Borrower; and

58

 

     (c) exercise on behalf of itself and the Lenders all rights and remedies available to it and
the Lenders under the Loan Documents;

     provided, however, that upon the occurrence of an actual or deemed entry of an
order for relief with respect to the Borrower under the Bankruptcy Code of the United States, the
obligation of each Lender to make Loans shall automatically terminate and the unpaid principal
amount of all outstanding Loans and all interest and other amounts as aforesaid shall automatically
become due and payable, in each case without further act of the Administrative Agent or any Lender.

     8.03 Application of Funds. After the exercise of remedies (subject to the terms of
the Intercreditor Agreement) provided for in Section 8.02 (or after the Loans have automatically
become immediately due and payable), any amounts received on account of the Obligations shall be
applied by the Administrative Agent in the following order, subject to the terms of the
Intercreditor Agreement:

     First, to payment of that portion of the Obligations constituting fees, indemnities,
expenses and other amounts (other than principal and interest, but including fees, charges and
disbursements of counsel to the Administrative Agent and amounts payable under Sections 2.15, 2.16
and 2.17) payable to the Administrative Agent or the trustee under the Mortgage, in each case, in
its capacity as such;

     Second, to payment of that portion of the Obligations constituting fees, indemnities
and other amounts (other than principal and interest) payable to the Lenders (including fees,
charges and disbursements of counsel to the respective Lenders and amounts payable under Sections
2.15, 2.16 and 2.17), ratably among them in proportion to the amounts described in this clause
Second payable to them;

     Third, to payment of that portion of the Obligations constituting accrued and unpaid
interest on the Loans and other Obligations, ratably among the Lenders in proportion to the
respective amounts described in this clause Third payable to them;

     Fourth, to payment of that portion of the Obligations constituting unpaid principal of
the Loans, ratably among the Lenders in proportion to the respective amounts described in this
clause Fourth held by them; and

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

     8.04 Production Proceeds. Notwithstanding that, by the terms of the Mortgage, the
Borrower and certain other Loan Parties are and will be assigning to the Administrative Agent and
Lenders all of the “Hydrocarbons” (as defined therein) and all proceeds of production
attributable to the Hydrocarbons or the Mortgaged Property, so long as no Default has occurred and
is continuing, the Borrower or such other Loan Party, as applicable, may continue to receive from
the purchasers of production all such proceeds attributable to the Hydrocarbons or the Mortgaged
Property, subject, however, to the Liens created under the Security Instruments, which Liens are
hereby affirmed and ratified. Upon the occurrence of a Default and during the continuance thereof,
the Administrative Agent and Lenders may exercise all rights and remedies granted under the
Security Instruments or under applicable law, including the right to obtain

59

 

possession of all proceeds attributable to the Hydrocarbons and the Mortgaged Property
then held by the Borrower or any other Loan Party and to receive directly from the purchasers of
production all other proceeds attributable to the Hydrocarbons and the Mortgaged Property. In no
case shall any failure, whether intended or inadvertent, by the Administrative Agent or Lenders to
collect directly any such proceeds attributable to the Hydrocarbons or the Mortgaged Property
constitute in any way a waiver, remission or release of any of their rights under the Security
Instruments or under applicable law, nor shall any release of any proceeds attributable to the
Hydrocarbons or the Mortgaged Property by the Administrative Agent or Lenders to the Borrower
constitute a waiver, remission or release of any other proceeds attributable to the Hydrocarbons or
the Mortgaged Property or of any rights of the Administrative Agent or Lenders to thereafter
collect other proceeds attributable to the Hydrocarbons or the Mortgaged Property or any other
rights.

ARTICLE IX.

ADMINISTRATIVE AGENT

     9.01 Appointment and Authority. Each of the Lenders hereby irrevocably appoints Bank
of America to act on its behalf as the Administrative Agent hereunder and under the other Loan
Documents 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 or thereof,
together with such actions and powers as are reasonably incidental thereto. The provisions of this
Article are solely for the benefit of the Administrative Agent and the Lenders, and neither the
Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such
provisions.

     9.02 Rights as a Lender. The Person serving as the Administrative Agent hereunder
shall have the same rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent and the term “Lender” or “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 Borrower 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 Lenders. Each Lender and each other party hereto
acknowledges and agrees that Bank of America is currently, may continue to be, and shall be
permitted to be, a First Lien Lender notwithstanding any potential or actual conflict that may now
or hereafter arise between the First Lien Lenders, on the one hand, and the Administrative Agent
and Lenders, on the other hand.

     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;

60

 

     (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 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 Borrower or any of its 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
Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be
necessary, under the circumstances as provided in Section 10.01 and Section 8.02) or (ii) in the
absence of its own gross negligence or willful misconduct (IT BEING THE INTENTION OF THE PARTIES
HERETO THAT THE ADMINISTRATIVE AGENT AND ANY RELATED PARTIES SHALL, IN ALL CASES, BE INDEMNIFIED
FOR ITS COMPARATIVE, CONTRIBUTORY OR SOLE NEGLIGENCE). 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 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 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 the Loans on the Closing Date which
condition by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent
may presume that such condition is satisfactory to such Lender unless the Administrative Agent
shall have received notice to the contrary from such Lender prior to the

61

 

making of such Loans. The Administrative Agent may consult with legal counsel (who may be
counsel for 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.

     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 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 Lenders, appoint a successor Administrative Agent meeting the
qualifications set forth above; provided that if the Administrative Agent shall notify the
Borrower and the Lenders that no qualifying Person has accepted such appointment, then such
resignation shall nonetheless become effective in accordance with such notice and (1) the retiring
Administrative Agent shall be discharged from its duties and obligations hereunder and under the
other Loan Documents (except that in the case of any collateral security held by the Administrative
Agent on behalf of the Lenders under any of the Loan Documents, the retiring Administrative Agent
shall continue to hold such collateral security until such time as a successor Administrative Agent
is appointed) and (2) all payments, communications and determinations provided to be made by, to or
through the Administrative Agent shall instead be made by or to each 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 any actions taken or omitted to
be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

62

 

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

     9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of
the bookrunner, the arranger, or any other agent 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 Lender hereunder.

     9.09 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 any Loan Party, 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 Borrower) shall be entitled and empowered, by intervention in such
proceeding or otherwise;

     (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans 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 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 2.12 and Section
10.04) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender 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 2.12 and
Section 10.04.

63

 

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 Obligations 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.

     9.10 Collateral and Guaranty Matters. The Lenders irrevocably authorize the
Administrative Agent, at its option and in its discretion,

     (a) to release any Lien on any property granted to or held by the Administrative Agent under
any Loan Document (i) upon termination of the Aggregate Commitments and payment in full of all
Obligations (other than contingent indemnification obligations), (ii) that is sold or to be sold as
part of or in connection with any sale permitted hereunder or under any other Loan Document, or

     (b) to subordinate any Lien on any property granted to or held by the Administrative Agent
under any Loan Document to the holder of any Lien on such property that is permitted by Section
7.01 if appropriate; and

     (c) to release any Guarantor from its obligations under the Guaranty if such Person ceases to
be a Restricted Subsidiary of the Borrower 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 or subordinate its interest in particular
types or items of property, or to release any Guarantor from its obligations under the Guaranty
pursuant to this Section 9.10.

     (b) Electronic Communications. Notices and other communications to the 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 Lender pursuant to Article II if such
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

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 Borrower shall indemnify the Administrative Agent, each 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 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.

66

 

     10.03 No Waiver; Cumulative Remedies. No failure by any Lender or the Administrative
Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or
privilege hereunder 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 are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

     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, and, so long as an Event of Default has occurred and is continuing any
Lender (including the fees, charges and disbursements of any counsel for the Administrative Agent,
and, so long as an Event of Default has occurred and is continuing, counsel for any 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 Loans made hereunder, including all such out-of-pocket expenses incurred during any workout,
restructuring or negotiations in respect of such Loans.

     (b) INDEMNIFICATION BY THE BORROWER. THE BORROWER SHALL INDEMNIFY THE ADMINISTRATIVE
AGENT (AND ANY SUB-AGENT THEREOF), EACH 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), AND SHALL INDEMNIFY AND HOLD
HARMLESS EACH INDEMNITEE FROM ALL FEES AND TIME CHARGES AND DISBURSEMENTS FOR ATTORNEYS WHO MAY BE
EMPLOYEES OF ANY INDEMNITEE, 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 OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY, (II) ANY 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 BORROWER OR ANY OF ITS SUBSIDIARIES, OR ANY ENVIRONMENTAL LIABILITY RELATED IN

67

 

ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (IV) ANY ACTUAL OR PROSPECTIVE CLAIM,
LITIGATION, 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, AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, IN ALL CASES,
WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY OR
SOLE NEGLIGENCE OF THE INDEMNITEE; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY
INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED
EXPENSES (X) ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE
JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE OR (Y)
RESULT FROM A CLAIM BROUGHT BY 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 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 Lenders. To the extent that the Borrower for any reason fails 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
(and without limiting its obligation to do so), each Lender severally agrees to pay to the
Administrative Agent (or any such sub-agent) or such Related Party, 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 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 respective obligations of the Lenders
under this Agreement are several and not joint and no Lender shall be responsible for the failure
of any other Lender to satisfy its obligations hereunder.

     (d) WAIVER OF CONSEQUENTIAL DAMAGES, ETC. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, 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, THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY, ANY 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

68

 

DISTRIBUTED BY IT 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.

     (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 Lender, the termination of the Aggregate Commitments
and the repayment, satisfaction or discharge of all the other Obligations.

     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 Lender or the Administrative Agent or any
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
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 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 Federal Funds Effective Rate from time to time in effect.
The obligations of the 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 the Borrower may not assign or otherwise transfer any of its
rights or obligations hereunder without the prior written consent of the Administrative Agent and
each Lender and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an Eligible Assignee in accordance with the provisions of subsection (b) of
this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of
this Section, or (iii) by way of pledge or assignment of a security interest subject to the
restrictions of subsection (f) of this Section (and any other attempted assignment or transfer by
any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall
be construed to confer upon any Person (other than the parties hereto, their respective successors
and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section
and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative
Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this
Agreement.

69

 

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

     (i) except in the case of an assignment of the entire remaining amount of the assigning
Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to
a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the
aggregate amount of the Commitment (which for this purpose includes Loans outstanding
thereunder) or, if the Commitment is not then in effect, the principal outstanding balance
of the Loans, of the assignor 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 $1,000,000, and the aggregate amount of the Commitment (which
for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in
effect, the principal outstanding balance of the Loans, assigned to the assignee 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 $1,000,000
and in an integral multiple of $1,000,000, unless in each case 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);

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

     (iii) [Reserved]; and

     (iv) 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 $2,500
(provided that in the event of two or more concurrent assignments to members of the same
Assignee Group (which may be effected by a suballocation of an assigned amount among members
of such Assignee Group) or two or more concurrent assignments by members of the same
Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its
Assignee Group), the Assignment Fee will be $2,500 for up to four concurrent assignments or
suballocations plus $500 for each additional concurrent assignment or suballocation), and
any Eligible Assignee to which any Loans are assigned that is not then a Lender shall
deliver to the Administrative Agent an Administrative Questionnaire.

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
Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the

70

 

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 2.15, Section 2.16,
Section 2.17, and Section 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 Note to the assignee Lender. Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this subsection shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with subsection (d) of this Section.

     (c) 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
Lenders, and the Commitments of, and principal amounts of the Loans 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 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 and copying by each of the Borrower at any reasonable time and from time
to time upon reasonable prior notice. In addition, at any time that a request for a consent for a
material or substantive change to the Loan Documents is pending, any Lender wishing to consult with
other Lenders in connection therewith may request and receive from the Administrative Agent a copy
of the Register.

     (d) Participations. Any Lender may at any time, without the consent of, or notice to,
the Borrower or the Administrative Agent, sell participations to any Person (other than a natural
person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a
“Participant”) in all or a portion of such Lender’s rights and/or obligations under this
Agreement (including all or a portion of its Commitment and/or the Loans owing to it);
provided that (i) such Lender’s obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrower, the Administrative Agent and the 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, waiver or other modification described in the first proviso to
Section 10.01 that affects such Participant. Subject to subsection (e) of this Section, the
Borrower agrees that each Participant shall be entitled to the benefits of Section 2.15, Section
2.16 and Section 2.17 to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to subsection (b) of this Section. To the extent permitted by law, each
Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender,
provided such Participant agrees to be subject to Section 2.18 as though it were a Lender.

71

 

     (e) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Section 2.15 or Section 2.16 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 2.17 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
2.17 as though it were a Lender.

     (f) Certain Pledges. Any Lender may, without the consent of the Administrative Agent
or the Borrower, at any time pledge or assign a security interest in all or any portion of its
rights under this Agreement (including under its Note, if any) to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank;
provided that no such pledge or assignment shall release such Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     (g) Electronic Execution of Assignments. The words “execution,” “signed,”
“signature,” and words of like import in any Assignment and Assumption 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.

     10.07 Treatment of Certain Information; Confidentiality. Each of the Administrative
Agent and the 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, trustees, agents, 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 (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 Lender, or any of their respective Affiliates on a nonconfidential basis
from a source other than the Borrower.

72

 

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

     10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing,
each Lender and each of their respective Affiliates is hereby authorized at any time and from time
to time, after obtaining the prior written consent of the Administrative Agent, 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 Lender or any such Affiliate to or for the credit
or the account of the Borrower against any and all of the obligations of the Borrower now or
hereafter existing under this Agreement or any other Loan Document to such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement or any other Loan
Document and although such obligations of the Borrower may be contingent or unmatured or are owed
to a branch or office of such Lender different from the branch or office holding such deposit or
obligated on such indebtedness. The rights of each Lender and its Affiliates under this Section
are in addition to other rights and remedies (including other rights of setoff) that such Lender or
its Affiliates may have. Each 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 herein to the contrary, if
at any time the interest rate applicable to any Loan, together with all fees, charges and other
amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance
with applicable law, the rate of interest payable in respect of such Loan hereunder, together with
all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent
lawful, the interest and Charges that would have been payable in respect of such Loan but were not
payable as a result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be increased (but not
above the Maximum Rate therefor) until the earlier to occur of the following events: (a) payment

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.

irrevocably

          (a) guarantees

     (i) the full and punctual payment when due, whether at stated maturity, by
required prepayment, declaration, acceleration, demand or otherwise, of all
Obligations of the Borrower and each other Loan Party now or hereafter existing
under the Second Lien Credit Agreement, the Notes and each other Loan Document to
which the Borrower is or may become a party, whether for principal, interest, fees,
expenses or otherwise;

     (ii) [Intentionally Omitted];

     (iii) all renewals, rearrangements, increases, extensions for any period,
substitutions, modification, amendments or supplements in whole or in part of any of
the above Loan Documents or obligations,

(including all such amounts which would become due but for the operation of the automatic
stay under Section 362(a) of the United States Bankruptcy Code, 11 U.S.C. §362(a), and the
operation of Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C.
§502(b) and §506(b)), and

     (b) indemnifies and holds harmless strictly in accordance with the terms of the Second
Lien Credit Agreement each Lender Party and each holder of a Note from the Borrower, for any
and all costs and expenses (including reasonable attorney’s fees and expenses) incurred by
such Lender Party or such holder, as the case may be, in enforcing any rights under this
Guaranty;

provided, however, that such Guarantor shall only be liable under this Guaranty to
the extent provided for in Article IV hereof. This Guaranty constitutes a guaranty of payment when
due and not of collection, and each Guarantor specifically agrees that it shall not be necessary or
required that any Lender Party or any holder of any Note exercise any right, assert any claim or
demand or enforce any remedy whatsoever against the Borrower or any other Loan Party (or any other
Person) before or as a condition to the obligations of such Guarantor hereunder. All payments
hereunder are to be made in the currency in which they are due under the Second Lien Credit
Agreement.

Exhibit D

     SECTION 2.2 Acceleration of Guaranty. Each Guarantor agrees that, in the event of the
dissolution or insolvency of the Borrower, such Guarantor, or any other Loan Party, or the
inability or failure of the Borrower, such Guarantor, or any other Loan Party to pay debts as they
become due, or an assignment by the Borrower, such Guarantor, or any other Loan Party for the
benefit of creditors, or the commencement of any case or proceeding in respect of the Borrower,
such Guarantor, or any other Loan Party under any bankruptcy, insolvency or similar laws, and if
such event shall occur at a time when any of the Obligations of the Borrower or any other Loan
Party may not then be due and payable, such Guarantor will pay to the Lender Parties forthwith the
full amount which would be payable hereunder by such Guarantor if all such Obligations were then
due and payable.

     SECTION 2.3 Guaranty Absolute, etc. This Guaranty shall in all respects be a
continuing, absolute, unconditional and irrevocable guaranty of payment, and shall remain in full
force and effect until all Obligations of the Borrower have been paid in full, all obligations of
each Guarantor hereunder shall have been paid in full. Each Guarantor guarantees that the
Obligations of the Borrower will be paid strictly in accordance with the terms of the Second Lien
Credit Agreement and each other Loan Document under which they arise, regardless of any law,
regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or
the rights of any Lender Party or any holder of any Note with respect thereto. The liability of
each Guarantor under this Guaranty shall be absolute, unconditional and irrevocable irrespective
of:

     (a) (i) any lack of validity, legality or enforceability of the Second Lien Credit
Agreement, any Note or any other Loan Document or any portion of any thereof or (ii) the
Second Lien Credit Agreement, any Note or any other Loan Document or any portion of any
thereof being void or voidable;

     (b) the failure of any Lender Party or any holder of any Note:

     (i) to assert any claim or demand or to enforce any right or remedy against the
Borrower, any other Loan Party or any other Person (including any other guarantor)
under the provisions of the Second Lien Credit Agreement, any Note, any other Loan
Document or otherwise, or

     (ii) to exercise any right or remedy against any other guarantor of, or
collateral securing, any Obligations of the Borrower or any other Loan Party;

     (c) any change in the time, manner or place of payment of, or in any other term of, all
or any of the Obligations of the Borrower or any other Loan Party, or any other extension,
compromise or renewal of any Obligation of the Borrower or any other Loan Party;

     (d) any reduction, limitation, impairment or termination of any Obligations of the
Borrower or any other Loan Party for any reason, including any claim of waiver, release,
surrender, alteration or compromise, and shall not be subject to (and each Guarantor hereby
waives any right to or claim of) any defense or setoff, counterclaim, recoupment or
termination whatsoever by reason of the invalidity, illegality,

Exhibit D

3

 

nongenuineness, irregularity, compromise, unenforceability of, or any other event or
occurrence affecting, any Obligations of the Borrower, any other Loan Party or otherwise;

     (e) any amendment to, extensions of, rescission, waiver, or other modification of, or
any consent to departure from, any of the terms of the Second Lien Credit Agreement, any
Note or any other Loan Document;

     (f) any addition, exchange, release, surrender or non-perfection of any collateral, or
any amendment to or waiver or release or addition of, or consent to departure from, any
other guaranty, held by any Lender Party or any holder of any Note, or interest therein
securing any of the Obligations of the Borrower or any other Loan Party; or

     (g) any other circumstance which might otherwise constitute a defense available to, or
a legal or equitable discharge of, the Borrower, any other Loan Party, any surety or any
guarantor.

     SECTION 2.4 Reinstatement. Each Guarantor agrees that this Guaranty shall continue to
be effective or be reinstated, as the case may be, if at any time any payment (in whole or in part)
of any of the Obligations guaranteed hereby is rescinded or must otherwise be restored by any
Lender Party or any holder of any Note upon the insolvency, bankruptcy or reorganization of the
Borrower, or any other Loan Party or otherwise, all as though such payment had not been made.

     SECTION 2.5 Waiver. Each Guarantor hereby expressly waives:

     (a) promptness, diligence, presentment, notice of acceptance and any other notice with
respect to any of the Obligations of the Borrower or any other Loan Party and this Guaranty
and any requirement that the Administrative Agent, any other Lender Party or any holder of
any Note or any interest therein protect, secure, perfect or insure any security interest or
Lien, or any property subject thereto, or exhaust any right or take any action against the
Borrower, any other Loan Party or any other Person (including any other guarantor) or entity
or any collateral securing the Obligations of the Borrower or any other Loan Party, as the
case may be; and

     (b) each and every right to which it may be entitled by virtue of the suretyship law of
the State of Texas including, without limitation, any rights it may have pursuant to Rule
31, Texas Rules of Civil Procedure, Section 17.001, Civil Practice and Remedies Code, and
Chapter 34 of the Texas Business and Commerce Code.

     SECTION 2.6 Waiver of Subrogation. Each Guarantor hereby irrevocably waives any claim
or other rights which it may now or hereafter acquire against the Borrower or any other Loan Party
that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations
under this Guaranty or any other Loan Document, including any right of subrogation, reimbursement,
contribution, exoneration, or indemnification, any right to participate in any claim or remedy of
the Lender Parties against the Borrower or any other Loan Party or any collateral which the
Administrative Agent now has or hereafter acquires, whether or

Exhibit D

4

 

not such claim, remedy or right arises in equity, or under contract, statute or common law,
including the right to take or receive from the Borrower or any other Loan Party, directly or
indirectly, in cash or other property or by set-off or in any manner, payment or security on
account of such claim or other rights. If any amount shall be paid to any Guarantor in violation
of the preceding sentence and the Obligations shall not have been paid in cash in full, such amount
shall be deemed to have been paid to such Guarantor for the benefit of, and held in trust for, the
Lender Parties, and shall forthwith be paid to the Lender Parties to be credited and applied upon
the Obligations, whether matured or unmatured; otherwise it shall be returned to remitter. Each
Guarantor acknowledges that it will receive direct and indirect benefits from the financing
arrangements contemplated by the Second Lien Credit Agreement and that the waiver set forth in this
Section is knowingly made in contemplation of such benefits.

     SECTION 2.7 Successors, Transferees and Assigns; Transfers of Notes. This Guaranty
shall:

     (a) be binding upon each Guarantor, and its successors, transferees and assigns
(provided, however, that such Guarantor may not assign any of its obligations hereunder
without the prior written consent of all Lenders); and

     (b) inure to the benefit of and be enforceable by each Agent and each other Lender
Party.

Without limiting the generality of the foregoing clause (b), any Lender may assign or
otherwise transfer (in whole or in part) any Note, Loan or interest therein held by it to any other
Person or entity, and such other Person or entity shall thereupon become vested with all rights and
benefits in respect thereof granted to such Lender under any Loan Document (including this
Guaranty) or otherwise, subject, however, to any contrary provisions in such assignment or
transfer, and to the provisions of Section 10.06 of the Second Lien Credit Agreement.

     SECTION 2.8 Taxes.

     (a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of any Guarantor hereunder or under any other Loan Document shall be made free and clear of and
without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if
any Guarantor shall be required by applicable law to deduct any Indemnified Taxes (including any
Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to additional sums payable
under this Section 2.8) the Administrative Agent or Lender, as the case may be, receives an
amount equal to the sum it would have received had no such deductions been made, (ii) such
Guarantor shall make such deductions and (iii) such Guarantor shall timely pay the full amount
deducted to the relevant Governmental Authority in accordance with applicable law.

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

Exhibit D

5

 

     (c) Indemnification by the Borrower. Each Guarantor shall indemnify the
Administrative Agent and each Lender, within 10 days after demand therefor, for the full amount of
any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent
or such 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. A certificate as
to the amount of such payment or liability delivered to the Guarantors by a Lender (with a copy to
the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a
Lender, 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 Guarantor to a Governmental Authority, each Guarantor 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) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which any Guarantor is resident
for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments
hereunder or under any other Loan Document shall deliver to the Guarantors (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by
the Guarantors or the Administrative Agent, such properly completed and executed documentation
prescribed by applicable law as will permit such payments to be made without withholding or at a
reduced rate of withholding. In addition, any Lender, if requested by the Guarantors or the
Administrative Agent, shall deliver such other documentation prescribed by applicable law or
reasonably requested by the Guarantors or the Administrative Agent as will enable the Guarantors or
the Administrative Agent to determine whether or not such Lender is subject to backup withholding
or information reporting requirements.

     (f) Treatment of Certain Refunds. If the Administrative Agent or any 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 any Guarantor or with respect to which any Guarantor has paid
additional amounts pursuant to this Section 2.8, it shall pay to such Guarantor an amount
equal to such refund (but only to the extent of indemnity payments made, or additional amounts
paid, by such Guarantor under this Section with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of the Administrative Agent or such 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 such Guarantor, upon the request of
the Administrative Agent or such Lender, agrees to repay the amount paid over to such Guarantor
(plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to
the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is
required to repay such refund to such Governmental Authority. This subsection shall not be
construed to require the Administrative Agent or any Lender to make available its tax returns (or
any other information relating to its taxes that it deems confidential) to any Guarantor or any
other Person.

Exhibit D

6

 

     The undersigned waives any statutory right to recover from any Lender Party any amount due to
any such Lender Party and paid by the undersigned under this Section 2.8.

     SECTION 2.9 Make-Whole Qualifications. Each Lender Party’s claims for reimbursements,
payments, indemnities or otherwise under Section 2.8 and the undersigned’s obligations with
respect thereto, shall be limited and qualified by and subject to the following:

     (a) the undersigned’s obligation to pay, satisfy or recognize such claim shall be
limited to costs or losses incurred within nine (9) months immediately prior to any demand
or request therefor upon the undersigned;

     (b) each Lender Party’s demand for reimbursement, payment or indemnity must be limited
to that which is being generally applied at the time by such Lender for comparable
guarantors and guaranties subject to similar provisions;

     (c) each Lender Party that asserts its rights with respect thereto or which is seeking
or imposing such reimbursement, payment or indemnity shall provide evidence regarding the
basis of such claim and the calculation and application thereof in reasonable detail and, in
determining such amount, each Lender Party may use reasonable methods of attribution and
averaging; and

     (d) each Lender Party that is seeking payment, indemnity or reimbursement pursuant to
Section 2.8 shall, if so requested by the undersigned use reasonable efforts
(subject to the overall policy considerations of such Lender Party) to designate a different
lending office hereunder if to do so will avoid the need for, or reduce the amount of, any
such payment, indemnity or reimbursement; provided that, Lender Party would, in its
sole but reasonable determination, suffer no material economic, legal or regulatory
disadvantage or burden.

     SECTION 2.10 Judgment. Each Guarantor hereby agrees that:

     (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert
a sum due hereunder in United States Dollars into another currency, such Guarantor agrees,
to the fullest extent permitted by law, that the rate of exchange used shall be that at
which in accordance with normal banking procedures the Administrative Agent could purchase
United States Dollars with such other currency on the Business Day preceding that on which
final judgment is given.

     (b) The obligation of such Guarantor in respect of any sum due from it to any Lender
Party or any holder of a Note hereunder shall, notwithstanding any judgment in a currency
other than United States Dollars, be discharged only to the extent that on the Business Day
following receipt by such Lender Party or such holder, as the case may be, of any sum
adjudged to be so due in such other currency such Lender Party or such holder, as the case
may be, may, in accordance with normal banking procedures, purchase United States Dollars
with such other currency; in the event that the United States Dollars so purchased are less
than the sum originally due to such Lender Party in United States Dollars, such Guarantor,
as a separate obligation and notwithstanding any such judgment, hereby indemnifies and holds
harmless such Lender Party and such

Exhibit D

7

 

holder against such loss, and if the United States Dollars so purchased exceed the sum
originally due to such Lender Party or such holder in United States Dollars, such Lender
Party or such holder, as the case may be, shall remit to such Guarantor such excess.

     SECTION 2.11 Intercreditor Agreement; Liens. Any Liens securing this Guaranty are
subject to the terms of that certain Intercreditor Agreement dated of even date herewith, among the
Borrower and the other Loan Parties party thereto, JPMorgan Chase Bank, N.A. (in its capacity as
administrative agent for the lenders party to that certain First Lien Credit Agreement), and
Administrative Agent, as the same may from time to time be amended, amended and restated,
supplemented or otherwise modified.

ARTICLE III

REPRESENTATIONS AND WARRANTIES

     SECTION 3.1 Each Guarantor hereby represents and warrants unto each Lender Party that each
representation or warranty contained in Article V of the Second Lien Credit Agreement is true and
correct as of the date hereof with respect to such Guarantor as if such representation or warranty
was set forth in full in this Guaranty and made by such Guarantor.

ARTICLE IV

LIMITATION ON OBLIGATIONS

     SECTION 4.1 Limitation on Obligations. The provisions of this Guaranty are severable,
and in any action or proceeding involving any state corporate law, or any state, federal or foreign
bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if
the obligations of any Guarantor under this Guaranty would otherwise be held or determined to be
avoidable, invalid or unenforceable on account of the amount of such Guarantor’s liability under
this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the
amount of such liability shall, without any further action by the Guarantors, the Administrative
Agent, any Lender or any Lender Party, be automatically limited and reduced to the highest amount
that is valid and enforceable as determined in such action or proceeding (such highest amount
determined hereunder being the relevant Guarantor’s “Maximum Liability”). This Section
4.1 with respect to the Maximum Liability of the Guarantors is intended solely to preserve the
rights of the Administrative Agent, the Lenders and the Lender Parties hereunder to the maximum
extent not subject to avoidance under applicable law, and no Guarantor nor any other person or
entity shall have any right or claim under this Section 4.1 with respect to the Maximum
Liability, except to the extent necessary so that the obligations of each Guarantor hereunder shall
not be rendered voidable under applicable law.

     SECTION 4.2 Maximum Liability. Each Guarantor agrees that the obligations guaranteed
under this Guaranty may at any time and from time to time exceed the Maximum Liability of each
Guarantor, and may exceed the aggregate Maximum Liability of all other Guarantors, without
impairing this Guaranty or affecting the rights and remedies of the Administrative Agent, the
Lenders and the Lender Parties hereunder. Nothing in this Section 4.2 shall be construed
to increase any Guarantor’s obligations hereunder beyond its Maximum Liability.

Exhibit D

8

 

     SECTION 4.3 Payments. In the event any Guarantor (a “Paying Guarantor”) shall
make any payment or payments under this Guaranty or shall suffer any loss as a result of any
realization upon any collateral granted by it to secure its obligations under this Guaranty, each
other Guarantor (each a “Non-Paying Guarantor”) shall contribute to such Paying Guarantor
an amount equal to such Non-Paying Guarantor’s “Pro Rata Share” of such payment or payments made,
or losses suffered, by such Paying Guarantor. For the purposes hereof, each Non-Paying Guarantor’s
“Pro Rata Share” with respect to any such payment or loss by a Paying Guarantor shall be determined
as of the date on which such payment or loss was made by reference to the ratio of (i) such
Non-Paying Guarantor’s Maximum Liability as of such date (without giving effect to any right to
receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Guarantor’s
Maximum Liability has not been determined, the aggregate amount of all monies received by such
Non-Paying Guarantor from the Borrower after the date hereof (whether by loan, capital infusion or
by other means) to (ii) the aggregate Maximum Liability of all Guarantors hereunder (including such
Paying Guarantor) as of such date (without giving effect to any right to receive, or obligation to
make, any contribution hereunder), or to the extent that a Maximum Liability has not been
determined for the Guarantors, the aggregate amount of all monies received by such Guarantors from
the Borrower after the date hereof (whether by loan, capital infusion or by other means). Nothing
in this Section 4.3 shall affect any Guarantor’s several liability for the entire amount of
the obligations guaranteed under this Guaranty (up to such Guarantor’s Maximum Liability). Each of
the Guarantors covenants and agrees that its right to receive any contribution under this Guaranty
from a Non-Paying Guarantor shall be subordinate and junior in right of payment to all the
Guaranteed Obligations. The provisions of this Section 4.3 are for the benefit of the
Administrative Agent, the Lenders and the Lender Parties and the Guarantors and may be enforced by
any one, or more, or all of them in accordance with the terms hereof.

ARTICLE V

provided herein and shall be deemed sufficiently given or furnished if delivered by personal
delivery, by telecopy (with telephonic confirmation of transmission, by delivery service with proof
of delivery, or by registered or certified United States mail, postage prepaid, to the Guarantors
at the address of the Guarantors specified on the signature pages hereto and to each Agent and each
Lender at their addresses specified on the signature pages to the Second Lien Credit Agreement
(unless changed by similar notice in writing given by the particular Person whose address is to be

     (a) in the case of personal delivery or delivery service, as of the date of first
attempted delivery at the address provided herein;

     (b) in the case of telecopy, upon receipt; or

     (c) in the case of registered or certified United States mail, three days after deposit

     SECTION 5.5 No Waiver; Remedies. In addition to, and not in limitation of,
Section 2.3 and Section 2.5, no failure on the part of any Lender Party or any
holder of a Note to exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other
or further exercise thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

     SECTION 5.6 Section Captions. Section captions used in this Guaranty are for
convenience of reference only, and shall not affect the construction of this Guaranty.

     SECTION 5.7 Setoff. In addition to, and not in limitation of, any rights of any Lender
Party or any holder of a Note under applicable law, each Lender Party and each such holder shall,
upon the occurrence of any Default described in Section 8.01(f) of the Second Lien Credit Agreement
or any Event of Default, have the right to appropriate and apply to the payment of the obligations
of any Guarantor owing to it hereunder, whether or not then due, and each Guarantor hereby grants
to each Lender Party and each such holder a continuing security interest in, any and all balances,
credits, deposits, accounts or moneys of such Guarantor then or thereafter maintained with such
Lender Party or such holder and any and all property of every kind or description of or in the name
of such Guarantor now or hereafter, for any reason or purpose whatsoever, in the possession or
control of, or in transit to, such Lender Party, such holder or any agent or bailee for such Lender
Party or such holder.

     SECTION 5.8 Severability. Wherever possible each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision
of this Guaranty shall be prohibited by or invalid under such law, such provision shall

Exhibit D

10

 

be ineffective to the extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Guaranty.

     SECTION 5.9 Counterparts. This Guaranty 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. Additional Restricted
Subsidiaries of the Borrower may from time to time execute one or more Counterpart Agreements to be
attached to this Guaranty and upon delivery of any such Counterpart Agreement to Administrative
Agent, such additional Restricted Subsidiary shall be a Guarantor hereunder for all purposes.

     SECTION 5.10 Subordination. Each Guarantor hereby subordinates and makes inferior to
the Obligations any and all indebtedness now or at any time hereafter owed to any such Guarantor by
Borrower or any other Guarantor (in this paragraph, the “Obligors”). Each Guarantor agrees
that during the continuance of any Event of Default it will neither permit any Obligor to repay
such indebtedness or any part thereof nor accept payment from any Obligor of such indebtedness or
any part thereof without the prior written consent of Administrative Agent. If any Guarantor
receives any such payment without the prior written consent of Administrative Agent, the amount so
paid shall be held in trust for the benefit of the Lender Parties, shall be segregated from the
other funds of such Guarantor, and shall forthwith be paid over to Administrative Agent to be held
by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in
part by Administrative Agent against, all or any portions of the Obligations, whether matured or
unmatured, in such order as Administrative Agent shall elect in accordance with the provisions of
the Second Lien Credit Agreement.

     SECTION 5.11 Governing Law, Entire Agreement. THIS GUARANTY SHALL BE GOVERNED BY AND
IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO THE PRINCIPLES
THEREOF RELATING TO CONFLICT OF LAW). THIS GUARANTY AND THE OTHER LOAN DOCUMENTS CONSTITUTE THE
ENTIRE UNDERSTANDING AMONG THE PARTIES HERETO WITH RESPECT TO THE SUBJECT MATTER HEREOF AND
SUPERSEDE ANY PRIOR AGREEMENTS, WRITTEN OR ORAL, WITH RESPECT THERETO.

     SECTION 5.12 Waiver of Jury Trial. EACH OF THE GUARANTORS, AGENTS AND LENDER PARTIES
HEREBY (a) IRREVOCABLY WAIVES, THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS GUARANTY OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED
THEREWITH, BEFORE OR AFTER MATURITY; (b) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED
BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY EXEMPLARY, PUNITIVE OR
CONSEQUENTIAL DAMAGES; (c) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR
COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY

THAT IT HAS BEEN INDUCED TO ENTER INTO AND ACCEPT

Exhibit D

11

 

THIS GUARANTY, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.

HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS GUARANTY OR ANY OTHER LOAN DOCUMENT,
OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF
THE LENDER PARTIES OR ANY GUARANTOR SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF

DISTRICT OF TEXAS; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY

DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET
FORTH ABOVE AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH
SUCH LITIGATION. EACH GUARANTOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY
REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF TEXAS. EACH
GUARANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION
BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT
IN AN INCONVENIENT FORUM. TO THE EXTENT THAT ANY GUARANTOR HAS OR HEREAFTER MAY ACQUIRE ANY
IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR
NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO

SECOND LIEN MORTGAGE, LINE OF CREDIT MORTGAGE, DEED OF TRUST,

ASSIGNMENT, SECURITY AGREEMENT AND FINANCING STATEMENT

     THIS SECOND LIEN MORTGAGE, LINE OF CREDIT MORTGAGE, DEED OF TRUST, ASSIGNMENT, SECURITY
AGREEMENT AND FINANCING STATEMENT (this “Mortgage”), dated as of ___, is from COG
OIL & GAS LP, a Texas limited partnership (herein the “Mortgagor”), having its chief
executive office at 550 W. Texas, Suite 1300, Midland, Texas 79701, to Jeffrey H. Rathkamp of
Boston, Massachusetts, as Trustee (herein the “Trustee”), and BANK OF AMERICA, N.A., having
its principal office at 100 Federal Street, Mail Stop MA DE 10008D, Boston, Massachusetts 02110
(herein called “Bank of America”), as Administrative Agent for the lenders and other
financial institutions parties to the Credit Agreement referred to below (herein, in such capacity,
together with any successor(s) thereto in such capacity, called the “Administrative
Agent”).

RECITALS:

     1. Pursuant to a Second Lien Credit Agreement dated as of ___, by and among Concho
Resources Inc., a Delaware corporation (the “Borrower”), Bank of America, N.A., as Administrative
Agent, and the other various commercial lending institutions (individually a “Lender” and
collectively the “Lenders”) from time to time parties thereto (together with all
amendments, supplements, restatements and other modifications, if any, thereafter made thereto, the
“Credit Agreement”), pursuant to which, upon the terms and subject to the conditions
therein set forth the Lenders have extended Commitments to make term Loans to the Borrower in an
aggregate principal amount not exceeding $200,000,000.00 at any time outstanding.

     2. The Loans to be made by the Lenders pursuant to the terms of the Credit Agreement may be
evidenced by Notes (as defined in the Credit Agreement and used herein with the same meaning) from
the Borrower, payable to the order of each respective Lender, each bearing interest at the rates
provided for in the Credit Agreement, and each containing provisions for payment of attorneys’ fees
and acceleration of maturity upon an Event of Default.

     3. It is a condition precedent to the making of the Loan under the Credit Agreement that the
Mortgagor have duly authorized the execution, delivery and performance of this Mortgage.

     4. The Mortgagor is a Subsidiary of the Borrower. In consideration of the financial and other
support that the Borrower has provided, and such financial and other support as the Borrower may in
the future provide, to the Mortgagor, and in order to induce the Lenders to extend credit under the
Credit Agreement, and because the Mortgagor has determined that executing this Mortgage is in its
interest and to its financial benefit, the Mortgagor is willing to execute this Mortgage.

     5. For all purposes of this Mortgage, unless the context otherwise requires:

performance of the Mortgagor’s obligations under the Credit Agreement and the other Loan Documents,
the Mortgagor hereby transfers, assigns, warrants and conveys to the Administrative Agent for the

parties and each of them shall be fully protected in so treating and regarding the Administrative
Agent and shall be under no obligation to see to the application by the Administrative Agent of any
such proceeds or payments received by it.

Exhibit F

     Section 3.2 Application of Proceeds. All payments received by the Administrative
Agent pursuant to Section 3.1 hereof shall be placed in a cash collateral account at the
principal office of the Administrative Agent and on the first business day of each calendar month
applied as set forth in Section 8.03 of the Credit Agreement.

     Section 3.3 No Liability of the Administrative Agent in Collecting. The
Administrative Agent is hereby absolved from all liability for failure to enforce collection of any

connection therewith, except the responsibility to account to the Mortgagor for funds actually
received.

     Section 3.4 Assignment Not a Restriction on the Administrative Agent’s Rights.
Nothing herein contained shall detract from or limit the absolute obligation of the Mortgagor to
make payment of the Indebtedness regardless of whether the proceeds assigned by this Article are
sufficient to pay the same, and the rights under this Article shall be in addition to all other
security now or hereafter existing to secure the payment of the Indebtedness.

     Section 3.5 Status of Assignment. Notwithstanding the other provisions of this
Article, the Trustee or any receiver appointed in judicial proceedings for the enforcement of this
Mortgage shall have the right to receive all of the Hydrocarbons herein assigned and the proceeds
therefrom after any Indebtedness has been declared due and payable in accordance with the
provisions of Section 4.1 hereof and to apply all of said proceeds as provided in
Section 3.2 hereof. Upon any sale of the Mortgaged Property or any part thereof pursuant

whatsoever kind or nature (all hereinafter in this Section 3.6 called “claims”)
made against or incurred by them or any of them and arising out of, in connection with, or as a
result of the assertion, either before or after the payment in full of the Indebtedness, that they
or any of them received Hydrocarbons herein assigned or the proceeds thereof claimed by third
persons, and the Trustee, the Administrative Agent, and the Lenders shall have the right to defend
against any such claims, employing attorneys therefor, and unless furnished with reasonable
indemnity, they or any of them shall have the right to pay or compromise and adjust all such
claims. The Mortgagor will indemnify and pay to the Trustee, the Administrative Agent or the
Lenders, as the case may be, any and all such amounts as may be paid in respect thereof or as may
be successfully adjudged against the Trustee, the Administrative Agent or the Lenders or any of
them. The obligations of the Mortgagor as hereinabove set forth in this Section 3.6 shall

ARTICLE IV

EVENTS OF DEFAULT

     Section 4.1 Events of Default Hereunder. As used herein, “event of default” means an

notice or demand of any kind, both of which are hereby expressly waived.

ARTICLE V

ENFORCEMENT OF THE SECURITY

Property. Upon the occurrence of an event of default and if such event shall be continuing,
the Trustee shall have the right and power to sell, to the extent permitted by law, at one or more
sales, as an entirety or in parcels, as it may elect, the real property constituting a part of the
Mortgaged Property, at such place or places and otherwise in such manner and upon such notice as
may be required by law, or, in the absence of any such requirement, as the Trustee may deem
appropriate, and to make conveyance to the purchaser or purchasers; and the Mortgagor shall warrant
title to such real property to such purchaser or purchasers. The Trustee may postpone the sale of
all or any portion of such real property by public announcement at the time and place of such sale,
and from time to time thereafter may further postpone such sale by public announcement made at the
time of sale fixed by the preceding postponement. The right of sale hereunder shall not be
exhausted by one or any sale, and the Trustee may make other and successive sales until all of the
Mortgaged Property be legally sold.

     Section 5.2 Rights of the Trustee with Respect to Personal Property Constituting a Part of
the Mortgaged Property. Upon the occurrence of an event of default and if such event shall be
continuing, the Trustee will have all rights and remedies granted by law, and particularly by the
Uniform Commercial Code, including, but not limited to, the right to take possession of all
personal property constituting a part of the Mortgaged Property, and for this purpose the Trustee
may enter upon any premises on which any or all of such personal property is situated and take
possession of and operate such personal property (or any portion thereof) or remove it therefrom.
The Trustee may require the Mortgagor to assemble such personal property and make it available to
the Trustee at a place to be designated by the Trustee which is reasonably convenient to all
parties. Unless such personal property is perishable or threatens to decline speedily in value or
is of a type customarily sold on a recognized market, the Trustee will give the Mortgagor
reasonable notice of the time and place of any public sale or of the time after which any private
sale or other disposition of such personal property is to be made. This requirement of sending
reasonable notice will be met if the notice is mailed by first-class mail, postage prepaid, to the
Mortgagor at the address shown below the signatures at the end of this Mortgage at least ten (10)
days before the time of the sale or disposition.

     Section 5.3 Rights of the Trustee with Respect to Fixtures Constituting a Part of the
Mortgaged Property. Upon the occurrence of an event of default and if such event shall be
continuing, the Trustee may elect to treat the fixtures constituting a part of the Mortgaged

Exhibit F

11

 

Property as either real property collateral or personal property collateral and then proceed
to exercise such rights as apply to such type of collateral.

     Section 5.4 Judicial Proceedings. Upon occurrence of an event of default and if such
event shall be continuing, the Trustee or the Administrative Agent, in lieu of or in addition to
exercising any power of sale hereinabove given, may proceed by a suit or suits in equity or at law,
whether for a foreclosure hereunder, or for the sale of the Mortgaged Property, or for the specific
performance of any covenant or agreement herein contained or in aid of the execution of any power
herein granted, or for the appointment of a receiver pending any foreclosure hereunder or the sale
of the Mortgaged Property, or for the enforcement of any other appropriate legal or equitable
remedy.

     Section 5.5 Possession of the Mortgaged Property. It shall not be necessary for the
Trustee to have physically present or constructively in his possession at any sale held by the
Trustee or by any court, receiver or public officer any or all of the Mortgaged Property; and the
Mortgagor shall deliver to the purchasers at such sale on the date of sale the Mortgaged Property
purchased by such purchasers at such sale, and if it should be impossible or impracticable for any
of such purchasers to take actual delivery of the Mortgaged Property, then the title and right of
possession to the Mortgaged Property shall pass to such purchaser at such sale as completely as if
the same had been actually present and delivered.

     Section 5.6 Certain Aspects of a Sale. The Administrative Agent shall have the right
to become the purchaser at any sale held by the Trustee or by any court, receiver or public
officer, and the Administrative Agent shall have the right to credit upon the amount of the bid
made therefor the amount payable out of the net proceeds of such sale to it. Recitals contained in
any conveyance made to any purchaser at any sale made hereunder shall conclusively establish the
truth and accuracy of the matters therein stated, including, without limiting the generality of the
foregoing, nonpayment of the unpaid principal sum of, and the interest accrued on, the Indebtedness
after the same have become due and payable, advertisement and conduct of such sale in the manner
provided herein or appointment of any successor Trustee hereunder.

     Section 5.7 Receipt to Purchaser. Upon any sale, whether made under the power of sale
herein granted and conferred or by virtue of judicial proceedings, the receipt of the Trustee, or
of the officer making sale under judicial proceedings, shall be sufficient discharge to the
purchaser or purchasers at any sale for his or their purchase money, and such purchaser or
purchasers, or his or their assigns or personal representatives, shall not, after paying such
purchase money and receiving such receipt of the Trustee or of such officer therefor, be obliged to
see to the application of such purchase money, or be in any wise answerable for any loss,
misapplication or nonapplication thereof.

     Section 5.8 Effect of Sale. Any sale or sales of the Mortgaged Property, whether
under the power of sale herein granted and conferred or by virtue of judicial proceedings, shall
operate to divest all right, title, interest, claim and demand whatsoever either at law or in
equity, of the Mortgagor of, in and to the premises and the property sold, and shall be a perpetual
bar, both at law and in equity, against the Mortgagor, and the Mortgagor’s successors or assigns,
and against any and all persons claiming or who shall thereafter claim all or any of the property
sold from, through or under the Mortgagor or the Mortgagor’s successors or assigns. Nevertheless,
the Mortgagor, if requested by the Trustee so to do, shall join in the execution and delivery of
all proper conveyances, assignments and transfers of the properties so sold.

Exhibit F

12

 

     Section 5.9 Application of Proceeds. The proceeds of any sale of the Mortgaged
Property, or any part thereof, whether under the power of sale herein granted and conferred or by
virtue of judicial proceedings, shall be applied as set forth in Section 8.03 of the Credit
Agreement.

     Section 5.10 The Mortgagor’s Waiver of Appraisement, Marshalling and Other Rights.
The Mortgagor agrees, to the full extent that the Mortgagor may lawfully so agree, that the
Mortgagor will not at any time insist upon or plead or in any manner whatever claim the benefit of
any appraisement, valuation, stay, extension or redemption law now or hereafter in force, in order
to prevent or hinder the enforcement or foreclosure of this Mortgage or the absolute sale of the
Mortgaged Property or the possession thereof by any purchaser at any sale made pursuant to any
provision hereof, or pursuant to the decree of any court of competent jurisdiction; but the
Mortgagor, for the Mortgagor and all who may claim through or under the Mortgagor, so far as the
Mortgagor or those claiming through or under the Mortgagor now or hereafter lawfully may, hereby
waives the benefit of all such laws. The Mortgagor, for the Mortgagor and all who may claim
through or under the Mortgagor, waives, to the extent that the Mortgagor may lawfully do so, any
and all right to have the Mortgaged Property marshalled upon any foreclosure of the lien hereof, or
sold in inverse order of alienation, and agrees that the Trustee or any court having jurisdiction
to foreclose such lien may sell the Mortgaged Property as an entirety. The Mortgagor, for the
Mortgagor and all who may claim through or under the Mortgagor, further waives, to the full extent
that the Mortgagor may lawfully do so, any requirement for posting a receiver’s bond or replevin
bond or other similar type of bond if the Trustee commences an action for appointment of a receiver
or an action for replevin to recover possession of any of the Mortgaged Property. If any law in
this paragraph referred to and now in force, of which the Mortgagor or the Mortgagor’s successor or
successors might take advantage despite the provisions hereof, shall hereafter be repealed or cease
to be in force, such law shall not thereafter be deemed to constitute any part of the contract
herein contained or to preclude the operation or application of the provisions of this paragraph.
Pursuant to Section 39-5-19, New Mexico Statutes, Annotated, 1978 Comp., as amended, the Mortgagor
agrees that as to the Mortgaged Property situated in the State of New Mexico, the redemption period
shall be shortened to one (1) month.

     Section 5.11 Costs and Expenses. All costs and expenses (including attorneys’ fees)
incurred by the Trustee, the Administrative Agent or the Lenders in protecting and enforcing their
rights hereunder, shall constitute a demand obligation owing by the Mortgagor to the party
incurring such costs and expenses and shall draw interest at an annual rate (herein called the
“Default Rate”) equal to 2% plus the rate applicable to ABR Loans until paid, all of which
shall constitute a portion of the Indebtedness.

     Section 5.12 Sale of the Mortgaged Property in Texas. If any Indebtedness is not paid
when due, whether by acceleration or otherwise, the Trustee is hereby authorized and empowered to
sell any part of the Mortgaged Property located in the State of Texas at public sale to the highest
bidder for cash in the area at the county courthouse of the county in Texas in which the Texas
portion of the Mortgaged Property or any part thereof is situated, as herein described, designated
by such county’s commissioner’s court for such proceedings, or if no area is so designated, at the
door of the county courthouse of said county, at a time between the hours of 10:00 A.M. and 4:00
P.M. which is no later than three (3) hours after the time stated in the notice described
immediately below as the earliest time at which such sale would occur on the

Exhibit F

13

 

first Tuesday of any month, after advertising the earliest time at which said sale would
occur, the place, and terms of said sale, and the portion of the Mortgaged Property to be sold, by
(a) posting (or by having some person or persons acting for the Trustee post) for at least
twenty-one (21) days preceding the date of the sale, written or printed notice of the proposed sale
at the courthouse door of said county in which the sale is to be made; and if such portion of the
Mortgaged Property lies in more than one county, one such notice of sale shall be posted at the
courthouse door of each county in which such part of the Mortgaged Property is situated and such
part of the Mortgaged Property may be sold in the area at the county courthouse of any one of such
counties designated by such county’s commissioner’s court for such proceedings, or if no area is
designated, at the courthouse door of such county, and the notice so posted shall designate in
which county such property shall be sold, and (b) filing in the office of the county clerk of each
county in which any part of the Texas portion of the Mortgaged Property which is to be sold at such
sale is situated a copy of the notice posted in accordance with the preceding clause (a). In
addition to such posting and filing of notice, the Lenders or other holder of the Indebtedness
shall, at least twenty-one (21) days preceding the date of sale, serve or cause to be served
written notice of the proposed sale by certified mail on the Mortgagor and on each other debtor, if
any, obligated to pay the Indebtedness according to the records of the Lenders or other holder of
the Indebtedness. Service of such notice shall be completed upon deposit of the notice, enclosed
in a postpaid wrapper properly addressed to the Mortgagor and such other debtors at their most
recent address or addresses as shown by the records of the Lenders or other holder of the
Indebtedness in a post office or official depository under the care and custody of the United
States Postal Service. The affidavit of any person having knowledge of the facts to the effect
that such a service was completed shall be prima facie evidence of the fact of
service. The Mortgagor agrees that no notice of any sale, other than as set out in this paragraph,
need be given by the Trustee, the Lenders or any other person. The Mortgagor hereby designates as
its address for the purpose of such notice the address set out on the signature page hereof; and
agrees that such address shall be changed only as provided in the Credit Agreement or by depositing
notice of such change enclosed in a postpaid wrapper in a post office or official depository under
the care and custody of the United States Postal Service, certified mail, postage prepaid, return
receipt requested, addressed to the Administrative Agent at the address for the Administrative
Agent set out herein (or to such other address as the Administrative Agent may have designated by
notice given as above provided to the Mortgagor and such other debtors). Any such notice of change
of address of the Mortgagor or other debtors or of the Administrative Agent shall be effective
three (3) business days after such deposit if such post office or official depository is located in
the State of Texas, otherwise to be effective upon receipt. The Mortgagor authorizes and empowers
the Trustee to sell the Texas portion of the Mortgaged Property in lots or parcels or in its
entirety as the Trustee shall deem expedient; and to execute and deliver to the purchaser or
purchasers thereof good and sufficient deeds of conveyance thereto by fee simple title, with
evidence of general warranty by the Mortgagor, and the title of such purchaser or purchasers when
so made by the Trustee, the Mortgagor binds itself to warrant and forever defend. Where portions
of the Mortgaged Property lie in different counties, sales in such counties may be conducted in any
order that the Trustee may deem expedient; and one or more such sales may be conducted in the same
month, or in successive or different months as the Trustee may deem expedient. Notwithstanding
anything to the contrary contained herein, the Trustee may postpone the sale provided for in this
Section 5.12 at any time without the necessity of a public announcement. The provisions
hereof with respect to the posting and giving of notices of sale are intended to comply with the
provisions of Section 51.002 of the Property Code of the State of Texas, effective January 1, 1984,
and in the event the requirements, or any notice, under such

Exhibit F

14

 

Section 51.002 of the Property Code of the State of Texas shall be eliminated or the
prescribed manner of giving such notices modified by future amendment to, or adoption of any
statute superseding, Section 51.002 of the Property Code of the State of Texas, the requirement for
such particular notices shall be deemed stricken from or modified in this Mortgage in conformity
with such amendment or superseding statute, effective as of the effective date thereof.

     Section 5.13 Effective as Mortgage. This Mortgage shall be effective as a mortgage as
well as a deed of trust and upon the occurrence of an event of default may be foreclosed as to any
of the Mortgaged Property in any manner permitted by applicable law, and any foreclosure suit may
be brought by Trustee or by Administrative Agent. To the extent, if any, required to cause this
Mortgage to be so effective as a mortgage as well as a deed of trust, Mortgagor hereby mortgages
the Mortgaged Property to Administrative Agent.

     Section 5.14 Operation of the Mortgaged Property by the Trustee. Upon the occurrence
of an event of default and in addition to all other rights herein conferred on the Trustee, the
Trustee (or any person, firm or corporation designated by the Trustee) shall have the right and
power, but shall not be obligated, to enter upon and take possession of any of the Mortgaged
Property, and to exclude the Mortgagor, and the Mortgagor’s agents or servants, wholly therefrom,
and to hold, use, administer, manage and operate the same to the extent that the Mortgagor shall be
at the time entitled and in its place and stead. The Trustee, or any person, firm or corporation
designated by the Trustee, may operate the same without any liability to the Mortgagor in
connection with such operations, except to use ordinary care in the operation of such properties,
and the Trustee or any person, firm or corporation designated by the Trustee, shall have the right
to collect, receive and receipt for all Hydrocarbons produced and sold from said properties, to
make repairs, purchase machinery and equipment, conduct work-over operations, drill additional
wells and to exercise every power, right and privilege of the Mortgagor with respect to the
Mortgaged Property. When and if the expenses of such operation and development (including costs of
unsuccessful work-over operations or additional wells) have been paid and the Indebtedness paid,
said properties shall, if there has been no sale or foreclosure, be returned to the Mortgagor.

     Section 5.15 Intercreditor Agreement. The lien created by this Mortgage on the
Mortgaged Property is junior and subordinate to the lien on such Mortgaged Property created by any
mortgage, deed of trust or similar instrument now or hereafter granted to the First Lien
Administrative Agent in such property, in accordance with the provisions of the Intercreditor
Agreement.

ARTICLE VI

MISCELLANEOUS PROVISIONS

     Section 6.1 Successor Trustee. Any Trustee may resign in writing addressed to the
Administrative Agent or may be removed at any time with or without cause by an instrument in
writing duly executed by the Administrative Agent. In case of the death, resignation or removal of
a Trustee, one or more successor Trustee may be appointed by the Administrative Agent by instrument
of substitution complying with any applicable requirements of law, and in the absence of any such
requirement without formality other than appointment and designation in writing. Such appointment
and designation shall be full evidence of the right and authority to make the same and of all facts
therein recited, and upon the making of any such appointment and

Exhibit F

15

 

designation this conveyance shall vest in the named successor Trustee all the estate and title
of the prior Trustee in all of the Mortgaged Property, and he or they shall thereupon succeed to
all the rights, powers, privileges, immunities and duties hereby conferred upon the prior Trustee.
All references herein to a Trustee or the Trustees shall be deemed to refer to each Trustee or the
Trustees, as applicable, from time to time acting hereunder.

     Section 6.2 Actions or Advances by the Administrative Agent or the Trustee. Each and
every covenant herein contained shall be performed and kept by the Mortgagor solely at the
Mortgagor’s expense. If the Mortgagor shall fail to perform or keep any of the covenants of
whatsoever kind or nature contained in this Mortgage, the Administrative Agent, the Trustee, any of
the Lenders or any receiver appointed hereunder, may, but shall not be obligated to, take action
and/or make advances to perform the same in the Mortgagor’s behalf, and the Mortgagor hereby agrees
to repay the expense of such action and such advances upon demand plus interest at an annual rate
equal to the Default Rate until paid or, in the event any promissory note evidences such
indebtedness, upon the terms and conditions thereof. No such advance or action by the
Administrative Agent, the Trustee, any of the Lenders or any receiver appointed hereunder shall be
deemed to relieve the Mortgagor from any default hereunder.

     Section 6.3 Defense of Claims. The Mortgagor will notify the Administrative Agent and
the Lenders, in writing, promptly of the commencement of any legal proceedings affecting the lien
or security interest hereof or the Mortgaged Property, or any part thereof, and will take such
action, employing attorneys agreeable to the Administrative Agent, as may be necessary or
appropriate to preserve the Mortgagor’s, the Trustee’s, the Administrative Agent’s and the Lenders’
rights affected thereby and/or to hold harmless the Trustee, the Administrative Agent and the
Lenders in respect of such proceedings; and should the Mortgagor fail or refuse to take any such
action, the Administrative Agent may, upon giving prior written notice thereof to the Mortgagor,
take such action in behalf and in the name of the Mortgagor and at the Mortgagor’s expense.
Moreover, the Administrative Agent, or the Trustee on behalf of the Administrative Agent and the
Lenders, may take such independent action in connection therewith as it or they may in its or their
discretion deem proper, the Mortgagor hereby agreeing that all sums advanced or all expenses
incurred in such actions plus interest at the Default Rate until paid, will, on demand, be
reimbursed, as appropriate, to the Administrative Agent, the Trustee, the Lenders, or any receiver
appointed hereunder. The obligations of the Mortgagor as hereinabove set forth in this Section
6.3 shall survive the release, termination, foreclosure or assignment of this Mortgage or any
sale hereunder.

     Section 6.4 The Mortgaged Property to Revert. If the Indebtedness shall be fully paid
and the covenants herein contained shall be well and truly performed, then all of the Mortgaged
Property shall revert to the Mortgagor and the entire estate, right, title and interest of the
Trustee and the Lenders shall thereupon cease; and the Administrative Agent in such case shall,
upon the request of the Mortgagor and at the Mortgagor’s cost and expense, deliver to the Mortgagor
proper instruments acknowledging satisfaction of this Mortgage.

     Section 6.5 Renewals, Amendments and Other Security. Renewals and extensions of the
Indebtedness may be given at any time and amendments may be made to agreements relating to any part
of such Indebtedness or the Mortgaged Property and the Trustee and the Lenders may take or may now
hold other security for the Indebtedness, all without notice to or consent of the Mortgagor. The
Trustee or the Lenders may resort first to such other security or any part thereof or first to the
security herein given or any part thereof, or from time to time to either or both,

Exhibit F

16

 

even to the partial or complete abandonment of either security, and such action shall not be a
waiver of any rights conferred by this Mortgage, which shall continue as a second lien upon and
perfected security interest in the Mortgaged Property not expressly released until the Notes and
all other Indebtedness secured hereby are fully paid.

     Section 6.6 Instrument an Assignment, etc. This Mortgage shall be deemed to be and
may be enforced from time to time as an assignment, chattel mortgage, contract, deed of trust,
financing statement, real estate mortgage, or security agreement, and from time to time as any one
or more thereof.

     Section 6.7 Limitation on Interest. No provision of this Mortgage or of the Notes
shall require the payment or permit the collection of interest in excess of the maximum permitted
by law or which is otherwise contrary to law. If any excess of interest in such respect is herein
or in the Notes provided for, or shall be adjudicated to be so provided for herein or in the Notes,
the Mortgagor shall not be obligated to pay such excess.

     Section 6.8 Unenforceable or Inapplicable Provisions. If any provision hereof is
invalid or unenforceable in any jurisdiction, the other provisions hereof shall remain in full
force and effect in such jurisdiction, and the remaining provisions hereof shall be liberally
construed in favor of the Trustee, the Administrative Agent and the Lender Parties in order to
effectuate the provisions hereof, and the invalidity of any provision hereof in any jurisdiction
shall not affect the validity or enforceability of any such provision in any other jurisdiction.
Any reference herein contained to a statute or law of a state in which no part of the Mortgaged
Property is situated shall be deemed inapplicable to, and not used in, the interpretation hereof.

     Section 6.9 Rights Cumulative. Each and every right, power and remedy herein given to
the Trustee, the Administrative Agent or the Lender Parties shall be cumulative and not exclusive;
and each and every right, power and remedy whether specifically herein given or otherwise existing
may be exercised from time to time and so often and in such order as may be deemed expedient by the
Trustee, the Administrative Agent or the Lenders, as the case may be, and the exercise, or the
beginning of the exercise, of any such right, power or remedy shall not be deemed a waiver of the
right to exercise, at the same time or thereafter, any other right, power or remedy. No delay or
omission by the Trustee, the Administrative Agent or the Lender Parties in the exercise of any
right, power or remedy shall impair any such right, power or remedy or operate as a waiver thereof
or of any other right, power or remedy then or thereafter existing.

     Section 6.10 Waiver by the Trustee. This instrument may be amended, modified,
revised, discharged, released or terminated only by a written instrument or instruments executed by
the Mortgagor and the Administrative Agent, but without the joinder of the Trustee which shall not
be required. Any alleged amendment, modification, revision, discharge, release or termination
which is not so documented shall not be effective as to any party. Any and all covenants in this
Mortgage may from time to time by instrument in writing signed by the Administrative Agent be
waived to such extent and in such manner as the Administrative Agent may desire, but no such waiver
shall ever affect or impair either the Trustee’s or the Lender Parties’ rights or liens or security
interests hereunder, except to the extent specifically stated in such written instrument.
Notwithstanding anything contained herein to the contrary, the Administrative Agent shall not be
required, except as expressly provided in the Credit Agreement, to obtain the consent of any Lender
Party in order to amend, modify, revise,

Exhibit F

17

 

discharge, release or terminate this Mortgage regardless of whether this Mortgage secures
Indebtedness owed to such Lender Party.

     Section 6.11 Action by Individual Trustee. Any Trustee from time to time serving
hereunder shall have the absolute right, acting individually, to take any action and to give any
consent and to exercise any right, remedy, power, privilege or authority conferred upon the
Trustee, and any action taken by either Trustee from time to time serving hereunder shall be
binding upon the other Trustee and no person dealing with any Trustee from time to time serving
hereunder shall be obligated to confirm the power and authority of such Trustee to act without the
concurrence of the other Trustee. In this Mortgage, the term “Trustee” shall mean the
Trustee hereinabove named and any successor Trustee.

     Section 6.12 Miscellaneous Warranties. The Mortgagor additionally represents and
warrants to the Trustee, the Administrative Agent and the Lenders that (a) the execution and
delivery of this Mortgage, and the performance by the Mortgagor of its obligations hereunder, are
within the corporate, partnership or limited liability company powers of the Mortgagor and have
been duly authorized by all necessary corporate, partnership or limited liability company action on
the part of the Mortgagor, and (b) this Mortgage has been duly executed and delivered on behalf of
the Mortgagor and is the legal, valid and binding obligation of the Mortgagor, enforceable in
accordance with its terms, the making and performance of which do not and will not contravene or
conflict with the charter or by-laws of the Mortgagor or violate or constitute a default under any
law, any presently existing requirement or restriction imposed by judicial, arbitral or any
governmental instrumentality or any agreement, instrument or indenture by which the Mortgagor is
bound.

     Section 6.13 Successors and Assigns. This Mortgage is binding upon the Mortgagor, the
Mortgagor’s successors and assigns, and shall inure to the benefit of the Trustee, their
successors, and the Administrative Agent, the Lenders, their respective successors and assigns, and
the provisions hereof shall likewise be covenants running with the land.

     Section 6.14 Article and Section Headings. The article and section headings in this
Mortgage are inserted for convenience of reference and shall not be considered a part of this
Mortgage or used in its interpretation.

     Section 6.15 Execution in Counterparts; Exhibits. This Mortgage may be executed in
any number of counterparts, each of which shall for all purposes be deemed to be an original and
all of which are identical, except that, to facilitate recordation or filing, in any particular
counterpart portions of Exhibit A hereto which describe properties situated in counties
other than the county in which such counterpart is to be recorded or filed may have been omitted.
The exhibits referenced in and attached to this instrument shall constitute and be a part of this
instrument for all purposes.

     Section 6.16 Special Filing as Financing Statement. This Mortgage and Deed of Trust
shall likewise be a Security Agreement and a Financing Statement. This Mortgage and Deed of Trust
shall be filed for record, among other places, in the real estate records of each county in which
any portion of the real property covered by the oil and gas leases described in Exhibit A
hereto is situated, and, when filed in such counties shall be effective as a financing statement
covering fixtures located on and as-extracted collateral relating to the oil and gas properties
described in Exhibit A hereto, which oil and gas properties (and accounts arising
therefrom) are

Exhibit F

18

 

to be financed at the wellheads of the wells located on the real property described in
Exhibit A hereto. At the option of the Administrative Agent, a carbon, photographic or
other reproduction of this Mortgage or of any financing statement covering the Mortgaged Property
or any portion thereof shall be sufficient as a financing statement and may be filed as such. By
the execution and delivery hereof, the Mortgagor hereby authorizes the Administrative Agent to file
any financing statements, and any amendments or continuation statements with respect thereto, as to
the Mortgaged Property pursuant to the applicable Uniform Commercial Code without the Mortgagor’s
signature thereon.

     Section 6.17 Notices. Any notice, request, demand or other instrument which may be
required to be given or served upon the Mortgagor shall be sufficiently given when mailed by
first-class mail, addressed to the Mortgagor at the address shown below the signatures at the end
of this Mortgage or to such different address as the Mortgagor shall have designated by written
notice received by the Trustee, the Administrative Agent or the Lenders.

     Section 6.18 No Partnership. Nothing contained in this instrument is intended to, or
shall be construed as, creating to any extent and in any manner whatsoever, any partnership, joint
venture, or association among the Mortgagor, the Trustee, the Administrative Agent, the Lender
Parties or their respective Affiliates, or in any way as to make the Administrative Agent, the
Lender Parties or the Trustee co-principals with the Mortgagor with reference to the Mortgaged
Property, and any inferences to the contrary are hereby expressly negated.

     Section 6.19 No Liability for Trustee. THE TRUSTEE SHALL NOT BE LIABLE FOR ANY ERROR
OF JUDGMENT OR ACT DONE BY THE TRUSTEE IN GOOD FAITH, OR BE OTHERWISE RESPONSIBLE OR ACCOUNTABLE
UNDER ANY CIRCUMSTANCES WHATSOEVER (INCLUDING, WITHOUT LIMITATION, THE TRUSTEE’S NEGLIGENCE),
EXCEPT FOR THE TRUSTEE’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. The Trustee shall have the right
to rely on any instrument, document or signature authorizing or supporting any action taken or
proposed to be taken by him hereunder, believed by him in good faith to be genuine. All moneys
received by the Trustee shall, until used or applied as herein provided, be held in trust for the
purposes for which they were received, but need not be segregated in any manner from any other
moneys (except to the extent required by law), and the Trustee shall be under no liability for
interest on any moneys received by him hereunder.

     Section 6.20 Line of Credit Mortgage. THE PARTIES HERETO AGREE THAT THIS MORTGAGE
CONSTITUTES A LINE OF CREDIT MORTGAGE PURSUANT TO SECTION 48-7-4 OF NEW MEXICO STATUTES 1978
ANNOTATED.

ACCORDANCE WITH, THE LAW OF THE STATE OF TEXAS APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED
ENTIRELY WITHIN SUCH STATE (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICT OF

ARISING UNDER FEDERAL LAW; AND EXCEPT THAT TO THE EXTENT THAT THE LAW OF A STATE IN WHICH A PORTION
OF THE MORTGAGED PROPERTY IS LOCATED (OR WHICH IS OTHERWISE APPLICABLE TO A PORTION OF THE
MORTGAGED PROPERTY) NECESSARILY GOVERNS WITH RESPECT TO PROCEDURAL AND SUBSTANTIVE MATTERS

Exhibit F

RELATING TO THE CREATION, PERFECTION AND ENFORCEMENT OF THE LIENS, SECURITY INTERESTS AND
OTHER RIGHTS AND REMEDIES OF THE LENDER PARTIES GRANTED HEREIN, THE LAW OF SUCH STATE SHALL APPLY

waives any claim or other rights which it may now or hereafter acquire against the Borrower or any
other Loan Party that arise from the existence, payment, performance or enforcement of such

of subrogation, reimbursement, exoneration, or indemnification, any right to participate in any
claim or remedy of Lender Parties against the Borrower or any other Loan Party or any collateral

right arises in equity, or under contract, statute or common law, including the right to take or
receive from the Borrower or any other Loan Party, directly or indirectly, in cash or other
property or by set-off or in any manner, payment or security on account of such claim or other
rights. If any amount shall be paid to any Pledgor in violation of the preceding sentence and the
Obligations shall not have been paid in cash in full and the Commitments have not been

benefit of, and held in trust for, Lender Parties, and shall forthwith be paid to Lender Parties to

Interests constituting Collateral, such Pledged Interests constitute one hundred percent (100%) of
each Pledgor’s interest in the Pledged Interest Issuer and the percentage of the total membership,
partnership and/or other equity interests in the Pledged Interest Issuer indicated on

received by or on behalf of the Administrative Agent with respect to the Pledged Notes, and all
other Collateral and other securities, instruments, security entitlements, financial assets,
investment property, proceeds, and rights from time to time received by or distributable to such
Pledgor in respect of any Collateral.

     SECTION 4.4. Dividends, etc. Each Pledgor agrees:

     (a) after any acceleration under the Second Lien Credit Agreement or
Default occurring on the Maturity Date, promptly upon receipt thereof by such Pledgor and
without any request therefor by the Administrative Agent, to deliver (properly endorsed
where required hereby or requested by the Administrative Agent) to the Administrative Agent
all Dividends, Distributions, all interest, all principal, all other cash payments, and all
proceeds of the Collateral, all of which shall be held by the Administrative Agent, subject
to the Intercreditor Agreement, as additional Collateral for use in accordance with
Section 6.4; and

     (b) after any Event of Default shall have occurred and be continuing and
the Administrative Agent has notified such Pledgor of the Administrative Agent’s intention
to exercise its voting power under this Section 4.4(b),

     (i) the Administrative Agent may, subject to the Intercreditor
Agreement, exercise (to the exclusion of such Pledgor) the voting power and all
other incidental rights of ownership with respect to any Pledged Shares, Pledged
Interests or other shares of capital stock, member interests or other ownership
interests constituting Collateral and EACH PLEDGOR HEREBY GRANTS THE ADMINISTRATIVE
AGENT AN IRREVOCABLE PROXY, EXERCISABLE UNDER SUCH CIRCUMSTANCES, TO VOTE THE
PLEDGED SHARES, THE PLEDGED INTERESTS AND SUCH OTHER COLLATERAL, WITH SUCH PROXY TO
REMAIN VALID UNTIL THE EARLIEST OF (A) SUCH TIME AS SUCH EVENT OF DEFAULT IS NO
LONGER CONTINUING; AND (B) THE INDEFEASIBLE PAYMENT IN FULL IN CASH OF ALL SECURED
OBLIGATIONS AND THE TERMINATION OR EXPIRATION OF ALL COMMITMENTS; and

     (ii) promptly to deliver to the Administrative Agent such
additional proxies and other documents as may be necessary to allow the
Administrative Agent to exercise such voting power.

     All Dividends, Distributions, interest, principal, cash payments, and proceeds which may at
any time and from time to time be held by each Pledgor but which such Pledgor is then obligated to
deliver to the Administrative Agent, subject to the Intercreditor Agreement, shall,

Exhibit G

10

 

until delivery to the Administrative Agent, be held by such Pledgor separate and apart from
its other property in trust for the Administrative Agent. The Administrative Agent agrees that
unless an Event of Default shall have occurred and be continuing and the Administrative Agent shall
have given the notice referred to in Section 4.4(b), each Pledgor shall have the exclusive
voting power with respect to any shares of capital stock, member interests, general or limited
partnership interests or other ownership interest (including any of the Pledged Shares or Pledged
Interests) constituting Collateral and the Administrative Agent shall, upon the written request of
such Pledgor, promptly deliver such proxies and other documents, if any, as shall be reasonably
requested by such Pledgor which are necessary to allow such Pledgor to exercise voting power with
respect to any such share of capital stock, member interests, general or limited partnership
interests or other ownership interests (including any of the Pledged Shares or Pledged Interests)
constituting Collateral; provided, however, that no vote shall be cast, or consent,
waiver, or ratification given, or action taken by such Pledgor that would impair any Collateral or
be inconsistent with or violate any provision of the Second Lien Credit Agreement or any other Loan
Document (including this Pledge Agreement).

     SECTION 4.5. Additional Undertakings. Each Pledgor will not, without the
prior written consent of the Administrative Agent, subject to the terms of the Intercreditor
Agreement:

     (a) enter into any agreement amending, supplementing, or waiving any
provision of any Pledged Note (including any underlying instrument pursuant to which such
Pledged Note is issued) or compromising or releasing or extending the time for payment of
any obligation of the maker thereof;

     (b) take or omit to take any action the taking or the omission of which
would result in any impairment or alteration of any obligation of the maker of any Pledged
Note or other instrument constituting Collateral;

     (c) cause or permit any change to be made in its name, identity, corporate
structure or state of incorporation or formation, or cause or permit any change in the
location of (i) any Collateral, or (ii) such Pledgor’s place of business (or, if it has more
than one place of business, its chief executive office), to a different jurisdiction from
the jurisdiction represented herein, unless such Pledgor shall have notified the
Administrative Agent of such change at least thirty (30) days prior to the effective date of
such change, and shall have first taken all action, if any, reasonably required by the
Administrative Agent, subject to the terms of the Intercreditor Agreement, for the purpose
of further perfecting or protecting the security interest in favor of the Administrative
Agent in the Collateral;

     (d) permit the issuance of (i) any additional equity interests of any
Pledged Share Issuer or Pledged Interest Issuer (unless immediately upon such issuance the
same are pledged and delivered to the Perfection Agent pursuant to the terms hereof to the
extent necessary to give the Administrative Agent a security interest after such issue in at
least the same percentage of such Pledgor’s outstanding interests as before such issue),
(ii) any securities or other ownership interests convertible voluntarily by the holder
thereof or automatically upon the occurrence or non-occurrence of any event or condition
into, or exchangeable for, any such shares or other ownership interests, or (iii) any

Exhibit G

11

 

warrants, options, contracts or other commitments entitling any Person other than a
Pledgor to purchase or otherwise acquire any such shares or other ownership interests; or

     (e) enter into any agreement creating or otherwise permit to exist, any
restriction or condition upon the transfer, voting or control of any Pledged Share or
Pledged Interest.

     Each Pledgor shall provide, or cause the relevant Pledged Share Issuer or Pledged Interest
Issuer to provide, the Administrative Agent with a copy of any amendment or supplement to, or
modification or waiver of, any term or provision of any of the by-laws and other organic documents
of the relevant Pledged Share Issuer or Pledged Interest Issuer, provided that such Pledgor shall
not enter into any such amendment, supplement, modification or waiver which could reasonably be
expected to be adverse to the interests of the Administrative Agent and the other Lender Parties.
Each Pledgor covenants and agrees that it shall not consent to or permit (i) any Pledged Interest
to be dealt with or traded on any securities exchanges or in any securities market or (ii) any
Pledged Interest Issuer to elect to have its Pledged Interests treated as a “security” under
Article 8 of the UCC.

     SECTION 4.6. Status of Pledged Interests. The registration of the Pledged
Interests on the permanent ownership records of Pledged Interest Issuer shall at all times be valid
and genuine and shall not be altered. The Pledged Interests at all times shall be duly authorized
and validly registered and shall not be registered in violation of the organic documents of each
Pledgor or the preemptive rights of any Person, if any, or of any agreement by which such Pledgor
or any Pledged Interest Issuer is bound.

     SECTION 4.7. Consent to Transfer. To the extent that the grant of a
security interest in the Collateral in favor of the Administrative Agent by any Pledgor pursuant to
this Pledge Agreement or the exercise of any remedies by the Administrative Agent, subject to the
terms of the Intercreditor Agreement, hereunder (or otherwise in accordance with applicable law)
would, in any case, violate the Organization Documents of any Pledged Interest Issuer, each Pledgor
hereby consents to such transfer for purposes of the Organization Documents of each Pledged
Interest Issuer.

ARTICLE V

ADMINISTRATIVE AGENT

     SECTION 5.1. Administrative Agent Appointed Attorney-in-Fact. Subject to
the Intercreditor Agreement, each Pledgor hereby irrevocably appoints the Administrative Agent such
Pledgor’s attorney-in-fact, with full authority in the place and stead of such Pledgor and in the
name of such Pledgor or otherwise, from time to time in the Administrative Agent’s discretion, to
take any action and to execute any writing or paper which the Administrative Agent may deem
necessary or advisable to accomplish the purposes of this Pledge Agreement, including without
limitation: after the occurrence and continuance of an Event of Default, to ask, demand, collect,
sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to
become due under or in respect of any of the Collateral; to receive, endorse,

Exhibit G

12

 

and collect any drafts or other instruments, documents and chattel paper which the
Administrative Agent may deem necessary in connection therewith; and to file any claims or take any
action or institute any proceedings which the Administrative Agent may deem necessary or desirable
for the collection of any of the Collateral or otherwise to enforce the rights of the
Administrative Agent with respect to any of the Collateral. Each Pledgor hereby acknowledges,
consents and agrees that the power of attorney granted pursuant to this Section is irrevocable and
coupled with an interest.

     SECTION 5.2. Administrative Agent May Perform. If any Pledgor fails to
perform any agreement contained herein, the Administrative Agent may itself perform, or cause
performance of, such agreement, subject to the terms of the Intercreditor Agreement, and the
expenses of the Administrative Agent incurred in connection therewith shall be payable by such
Pledgor pursuant to Section 6.5.

     SECTION 5.3. Administrative Agent Has No Duty. The powers conferred on
the Administrative Agent hereunder are solely to protect its interest (on behalf of the Lender
Parties) in the Collateral and shall not impose any duty on it to exercise any such powers. Except
for reasonable care of any Collateral in its possession and the accounting for moneys actually
received by it hereunder, the Administrative Agent shall have no duty as to any Collateral or
responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Pledged Shares, whether or not the
Administrative Agent has or is deemed to have knowledge of such matters or (b) taking any necessary
steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

     SECTION 5.4. Reasonable Care. The Administrative Agent is required to
exercise reasonable care in the custody and preservation of any of the Collateral in its
possession; provided, however, the Administrative Agent shall be deemed to have
exercised reasonable care in the custody and preservation of any of the Collateral, if it takes
such action for that purpose as each Pledgor reasonably requests in writing at times other than
upon the occurrence and during the continuance of any Event of Default, but failure of the
Administrative Agent to comply with any such request at any time shall not in itself be deemed a
failure to exercise reasonable care.

ARTICLE VI

REMEDIES

     SECTION 6.1. Certain Remedies. If any Event of Default shall have
occurred and be continuing, then subject to the terms of the Intercreditor Agreement:

     (a) the Administrative Agent may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available to it, all
the rights and remedies of a secured party on default under the UCC (whether or not the UCC
applies to the affected Collateral) and also may, without notice except as specified below,
(or, if notice cannot be waived under the UCC, as required to be provided by the UCC) sell
the Collateral or any part thereof in one or more parcels at public or private sale, at any
of the Administrative Agent’s offices or elsewhere, for cash, on credit or for future
delivery, and upon such other terms as the Administrative Agent may deem

Exhibit G

13

 

commercially reasonable. Each Pledgor agrees that, to the extent notice of sale shall
be required by law, at least ten days’ prior notice to such Pledgor of the time and place of
any public sale or the time after which any private sale is to be made shall constitute
reasonable notification. The Administrative Agent shall not be obligated to make any sale
of Collateral regardless of notice of sale having been given. The Administrative Agent may
adjourn any public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time and place to
which it was so adjourned.

     (b) The Administrative Agent may transfer all or any part of the Collateral
into the name of the Administrative Agent or its nominee, with or without disclosing that
such Collateral is subject to the lien and security interest hereunder, notify the parties
obligated on any of the Collateral to make payment to the Administrative Agent of any amount
due or to become due thereunder, enforce collection of any of the Collateral by suit or
otherwise, and surrender, release or exchange all or any part thereof, or compromise or
extend or renew for any period (whether or not longer than the original period) any
obligations of any nature of any party with respect thereto, endorse any checks, drafts, or
other writings in each Pledgor’s name to allow collection of the Collateral, take control of
any proceeds of the Collateral, and execute (in the name, place and stead of each Pledgor)
endorsements, assignments, stock powers and other instruments of conveyance or transfer with
respect to all or any of the Collateral.

     SECTION 6.2. Securities Laws. If the Administrative Agent shall determine
to exercise its right to sell all or any of the Collateral pursuant to Section 6.1 and in
accordance with and subject to the terms of the Intercreditor Agreement, each Pledgor agrees that,
upon the reasonable request of the Administrative Agent, such Pledgor will, at its own expense:

     (a) execute and deliver, and cause each issuer of the Collateral
contemplated to be sold and the directors and officers thereof to execute and deliver, all
such instruments and documents, and do or cause to be done all such other acts and things,
as may be necessary or, in the opinion of the Administrative Agent, advisable to register
such Collateral under the provisions of the Securities Act of 1933, as from time to time
amended (the “Securities Act”), and to cause the registration statement relating
thereto to become effective and to remain effective for such period as prospectuses are
required by law to be furnished, and to make all amendments and supplements thereto and to
the related prospectus which, in the opinion of the Administrative Agent, are necessary or
advisable, all in conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto;

     (b) use its commercially reasonable efforts to qualify the Collateral under
the state securities or “Blue Sky” laws and to obtain all necessary governmental approvals
for the sale of the Collateral, as requested by the Administrative Agent;

     (c) cause each such issuer to make available to its security holders, as
soon as practicable, an earnings statement that will satisfy the provisions of Section 11(a)
of the Securities Act; and

Exhibit G

14

 

     (d) do or cause to be done all such other acts and things as may be
necessary to make such sale of the Collateral or any part thereof valid and binding and in
compliance with applicable law.

     Each Pledgor further acknowledges the impossibility of ascertaining the amount of damages that
would be suffered by the Administrative Agent or the Lender Parties by reason of the failure by
such Pledgor to perform any of the covenants contained in this Section and, consequently, agrees
that, if the Pledgor shall fail to perform any of such covenants, it shall pay, as liquidated
damages and not as a penalty, an amount equal to the value (as determined by the Administrative
Agent) of the Collateral on the date the Administrative Agent shall demand compliance with this
Section.

     SECTION 6.3. Compliance with Restrictions. Each Pledgor agrees that in
any sale of any of the Collateral whenever an Event of Default shall have occurred and be
continuing, the Administrative Agent is hereby authorized to comply with any limitation or
restriction in connection with such sale as it may be advised by counsel is necessary in order to
avoid any violation of applicable law (including compliance with such procedures as may restrict
the number of prospective bidders and purchasers, require that such prospective bidders and
purchasers have certain qualifications, and restrict such prospective bidders and purchasers to
persons who will represent and agree that they are purchasing for their own account for investment
and not with a view to the distribution or resale of such Collateral), or in order to obtain any
required approval of the sale or of the purchaser by any governmental regulatory authority or
official, and such Pledgor further agrees that such compliance shall not result in such sale being
considered or deemed not to have been made in a commercially reasonable manner, nor shall the
Administrative Agent be liable nor accountable to such Pledgor for any discount allowed by the
reason of the fact that such Collateral is sold in compliance with any such limitation or
restriction.

     SECTION 6.4. Application of Proceeds. Subject to the terms of the
Intercreditor Agreement, all cash proceeds received by the Administrative Agent in respect of any
sale of, collection from, or other realization upon, all or any part of the Collateral may, in the
discretion of the Administrative Agent, be held by the Administrative Agent as additional
collateral security for, or then or at any time thereafter be applied (after payment of any amounts
payable to the Administrative Agent pursuant to clauses (a) and (b) of Section 10.04 of the Second
Lien Credit Agreement and Section 6.5) in whole or in part by the Administrative Agent
against, all or any part of the Secured Obligations in the order set forth in Section 8.03 of the
Second Lien Credit Agreement.

     Any surplus of such cash or cash proceeds held by the Administrative Agent and remaining after
payment in full of all the Secured Obligations, and the termination of all Commitments, shall be
paid over to each Pledgor or to whomsoever may be lawfully entitled to receive such surplus.

     SECTION 6.5. Indemnity and Expenses. Each Pledgor hereby indemnifies and
holds harmless the Administrative Agent from and against any and all claims, losses, and
liabilities arising out of or resulting from this Pledge Agreement (including enforcement of this
Pledge Agreement), except claims, losses, or liabilities resulting from the Administrative Agent’s
gross

Exhibit G

15

 

negligence or willful misconduct. Upon demand, each Pledgor will pay to the Administrative
Agent the amount of any and all reasonable expenses, including the reasonable fees and
disbursements of its counsel and of any experts and agents, which the Administrative Agent may
incur in connection with:

     (a) the administration of this Pledge Agreement, the Second Lien Credit
Agreement and each other Loan Document;

     (b) the custody, preservation, use, or operation of, or the sale of,
collection from, or other realization upon, any of the Collateral;

     (c) the exercise or enforcement of any of the rights of the Administrative
Agent hereunder; or

     (d) the failure by any Pledgor to perform or observe any of the provisions
hereof.

     SECTION 6.6. Warranties. The Administrative Agent may sell the Collateral
without giving any warranties or representations as to the Collateral. The Administrative Agent
may disclaim any warranties of title or the like. This procedure will not be considered to
adversely affect the commercial reasonableness of any sale of the Collateral.

     SECTION 6.7. Intercreditor Agreement. The security interest granted by
this Pledge Agreement on the Collateral is junior and subordinate to the security interest in such
Collateral created by any pledge agreement, security agreement or similar instrument now or
hereafter granted to the First Lien Administrative Agent in such Collateral, in accordance with the
provisions of the Intercreditor Agreement.

ARTICLE VII

MISCELLANEOUS PROVISIONS

     SECTION 7.1. Loan Document. This Pledge Agreement is a Loan Document
executed pursuant to the Second Lien Credit Agreement and shall (unless otherwise expressly
indicated herein) be construed, administered and applied in accordance with the terms and
provisions thereof.

     SECTION 7.2. Amendments, Etc.. No amendment to or waiver of any provision
of this Pledge Agreement, nor consent to any departure by any Pledgor herefrom, shall in any event

such waiver or consent shall be effective only in the specific instance and for the specific
purpose for which it is given.

     SECTION 7.3. Protection of Collateral. The Administrative Agent may from
time to time, at its option, perform any act which any Pledgor agrees hereunder to perform and
which such Pledgor shall fail to perform after being requested in writing so to perform (it being
understood that no such request need be given after the occurrence and during the continuance of an
Event of Default) and the Administrative Agent may from time to time take any other action

Exhibit G

16

 

which the Administrative Agent reasonably deems necessary for the maintenance, preservation or
protection of any of the Collateral or of its security interest therein.

     SECTION 7.4. Obligations Not Affected. The obligations of each Pledgor
under this Pledge Agreement shall remain in full force and effect without regard to, and shall not
be impaired or affected by:

     (a) any amendment or modification or addition or supplement to the Second
Lien Credit Agreement, any Note, any other Loan Documents, any instrument delivered in
connection therewith, or any assignment or transfer thereof;

     (b) any exercise, non-exercise, or waiver by the Administrative Agent or
any Lender of any right, remedy, power, or privilege under or in respect of, or any release
of any guaranty or collateral provided pursuant to, this Pledge Agreement, the Second Lien
Credit Agreement, Pledgors’ Guaranty or any other Loan Document;

     (c) any waiver, consent, extension, indulgence, or other action or inaction
in respect of this Pledge Agreement, the Second Lien Credit Agreement, Pledgors’ Guaranty or

composition, liquidation, or the like, of any Pledgor or any other Person, whether or not
such Pledgor shall have notice or knowledge of any of the foregoing.

     SECTION 7.5. Notices. All notices, requests, consents, demands and other
communications required or permitted hereunder shall be in writing, unless otherwise specifically
provided herein and shall be deemed sufficiently given or furnished if delivered by personal

of delivery, or by registered or certified United States mail, postage prepaid, to the Pledgors at
the address of the Pledgors specified on the signature pages hereto and to each Agent and each
Lender at their addresses specified on the signature pages to the Second Lien Credit Agreement

     SECTION 7.6. No Waiver; Remedies. No failure on the part of any Lender
Party or any holder of a Note to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other right. The remedies
herein provided are cumulative and not exclusive of any remedies provided by law.

     SECTION 7.7. Section Captions. Section captions used in this Pledge
Agreement are for convenience of reference only, and shall not affect the construction of this
Pledge Agreement.

     SECTION 7.8. Severability. Wherever possible each provision of this
Pledge Agreement shall be interpreted in such manner as to be effective and valid under applicable
law,

Exhibit G

17

 

but if any provision of this Pledge Agreement shall be prohibited by or invalid under such
law, such provision shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this Pledge Agreement.

     SECTION 7.9. Execution in Counterparts, Effectiveness, etc. This Pledge
Agreement may be executed by the parties hereto in several counterparts, each of which shall be
executed by each Pledgor and the Administrative Agent and be deemed to be an original and all of
which shall constitute together but one and the same agreement. This Pledge Agreement shall become
effective as against a Pledgor when counterparts hereof executed on behalf of such Pledgor and the
Administrative Agent shall have been received by the Administrative Agent.

     SECTION 7.10. Filing as a Financing Statement. At the option of the
Administrative Agent, this Pledge Agreement, or a carbon, photographic or other reproduction of
this Pledge Agreement or of any UCC financing statement, continuation statement or amendments
thereto, covering all of the Collateral or any portion thereof shall be sufficient as a UCC
financing statement and may be filed as such without the signature of any Pledgor where and to the
full extent permitted by applicable law. Each Pledgor hereby expressly authorizes the
Administrative Agent to file UCC financing statements, continuation statements and amendments with
respect to the Collateral without such Pledgor’s signature (to the extent permitted by applicable
law).

     SECTION 7.11. Governing Law, Entire Agreement. THIS PLEDGE AGREEMENT
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF TEXAS APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE (WITHOUT GIVING EFFECT TO THE
PRINCIPLES THEREOF RELATING TO CONFLICT OF LAW); PROVIDED THAT THE ADMINISTRATIVE AGENT AND
EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW. THIS PLEDGE AGREEMENT AND THE OTHER
LOAN DOCUMENTS CONSTITUTE THE ENTIRE UNDERSTANDING AMONG THE PARTIES HERETO WITH RESPECT TO THE
SUBJECT MATTER HEREOF AND SUPERSEDE ANY PRIOR AGREEMENTS, WRITTEN OR ORAL, WITH RESPECT THERETO.

     SECTION 7.12. Waiver of Jury Trial. EACH OF EACH PLEDGOR, AGENTS AND
LENDERS HEREBY (a) IRREVOCABLY WAIVES, THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS PLEDGE AGREEMENT OR ANY TRANSACTION CONTEMPLATED THEREBY OR
ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY; (b) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY EXEMPLARY,
PUNITIVE OR CONSEQUENTIAL DAMAGES; (c) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR
AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH

OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS,
THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.

     SECTION 7.13. Forum Selection and Consent to Jurisdiction. ANY LITIGATION
BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS PLEDGE AGREEMENT OR ANY OTHER
LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN)
OR ACTIONS OF LENDER PARTIES OR ANY PLEDGOR SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE
COURTS OF THE STATE OF TEXAS SITTING IN DALLAS COUNTY OR IN THE UNITED STATES DISTRICT COURT FOR
THE NORTHERN DISTRICT OF TEXAS; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY PROPERTY MAY BE BROUGHT, AT ADMINISTRATIVE AGENT’S OPTION, IN THE COURTS OF
ANY JURISDICTION WHERE SUCH PROPERTY MAY BE FOUND. EACH PLEDGOR HEREBY EXPRESSLY AND IRREVOCABLY
SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF TEXAS SITTING IN DALLAS COUNTY AND THE
UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS FOR THE PURPOSE OF ANY SUCH
LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY
IN CONNECTION WITH SUCH LITIGATION. EACH PLEDGOR FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF
PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF
TEXAS. EACH PLEDGOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS
BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT ANY PLEDGOR HAS OR HEREAFTER MAY ACQUIRE
ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR
NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY, EACH PLEDGOR HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS
OBLIGATIONS UNDER THIS PLEDGE AGREEMENT.

     THIS WRITTEN PLEDGE AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

     THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Agreement pursuant to which this Note has been pledged to the Administrative Agent as security for
the Obligations outstanding from time to time under the Second Lien Credit Agreement and each other
Loan Document.

     In addition to, but not in limitation of, the foregoing, the Maker further agrees to pay all

GAS PURCHASE CONTRACT

     This Gas Purchase Contract (“Contract”) is entered as of  November 1, 2006 (“Effective
Date”), between COG OIL & GAS LP (“Seller”) and DUKE ENERGY FIELD SERVICES, LP (“Buyer”).

     For and in consideration of the mutual covenants contained herein, the parties agree as
follows:

     1. COMMITMENT. Except as to lands and leases committed to another purchaser as of the
Effective Date, Seller will sell and deliver and Buyer will purchase and receive gas produced from
all wells now or later located on all oil and gas interests now or later owned or controlled by
Seller on or allocated to the following lands in Eddy and Lea Counties, New Mexico:

          See Schedules “A” and “B” attached hereto and incorporated by reference.
Definitions and General Terms and Conditions included in this Contract are attached as Exhibit A.
All Exhibits referenced herein are attached and incorporated by reference.

     2. DELIVERY POINTS. The Delivery Points for gas to be delivered by Seller to
Buyer for existing sources of production will be at the inlets of Buyer’s Facilities at a mutually
agreeable site at or near Seller’s sources of production. The Delivery Points for future sources
of production committed under this Contract will be established under Section B.2 of Exhibit A.
Title to the gas and all its components shall pass to and vest in Buyer at the Delivery Points
without regard to the purposes for which Buyer may later use or sell the gas or its components.

     3. DELIVERY PRESSURE.

     3.1 Delivery Pressure. Seller will deliver the Gas at the Delivery Points at a
pressure sufficient to enable it to enter Buyer’s Facilities against the working pressure at
reasonably uniform rates of delivery, not to exceed the maximum allowable operating pressure
established by Buyer or pressures that prevent others from producing ratably.

     3.2 Penalty for Exceeding Contract Pressure.

     (a) Notwithstanding any other provision of this Contract, including without limitation,
Section B.4 of Exhibit A, Buyer shall maintain (1) a System Average Working Pressure (as defined
below) of no greater than *** (***) psig for the Delivery Points located on the acreage described
in Schedule A (“Loco Hills Area Contract Pressure”), and (2) a System Average Working Pressure (as
defined below) of no greater than *** (***) psig for Delivery Points located on the acreage

 

 

described in Schedule B (“Non-Loco Hills Area Contract Pressure”). “Contract Pressure” shall
mean either the Loco Hills Area Contract Pressure or the Non-Loco Hills Area Contract Pressure, as
the case may be.

     Notwithstanding the foregoing, the following lands (the “Willow Lands”) shall, at Seller’s
option, be released from the terms of this Contract and deleted from Schedule B for all purposes
if for any Month after the second anniversary of the Effective Date the average pressure at the
Delivery Point located on such lands exceeds *** (***) psig: SE/4, Section 16, T-17S, R-31E, Eddy
County, New Mexico.

     Seller’s option to terminate this Contract as to the Willow Lands shall terminate on March
31, 2009, unless exercised in writing prior to such date. If Seller does not exercise such
option, then as of April 1, 2009, and thereafter, the Willow Lands shall be considered to be a
part of the Loco Hills Area and Schedules A and B shall be deemed amended by deleting the Willow
Lands from Schedule B and adding the Willow Lands to Schedule A for all purposes.

     (b) If the System Average Working Pressure in either the Loco Hills Area or the Non-Loco
Hills Area exceeds the applicable Contract Pressure on a monthly average basis for two consecutive
Months (a “System Default Occurrence”) , then Seller shall be paid a pressure penalty payment
(“Pressure Penalty Payment”). The Pressure Penalty Payment shall commence as of the first day of
the second Month of such System Default Occurrence, and continue for each month thereafter, and
end the first day of the Month during which Buyer provides a System Average Working Pressure below
the specified Contract Pressure. The System Pressure Penalty Payment shall be equal to ***
(***) percentage points added to the payment percentages due Seller under Paragraph 5.1 of this
Contract. The Pressure Penalty Payment shall only apply to the respective areas described in (a)
above in which there was a System Default Occurrence (i.e., Loco Hills Area Delivery Points shall
be paid a Pressure Penalty Payment only when the Loco Hills Area Contract Pressure is exceeded for
two consecutive Months, and Non-Loco Hills Area wells shall be paid a Pressure Penalty Payment
only when the Non-Loco Hills Area Contract Pressure is exceeded for two consecutive Months).

     (c) Buyer may make Pressure Penalty Payments due hereunder to Seller as either (1) an
increase in the payment percentages reflected on Seller’s Gas statement for the applicable Month,
or (2) in the form of a separate credit to Seller on Seller’s Gas statement for the applicable
Month.

- 2 -

 

     (d) “System Average Working Pressure” for the Loco Hills Area shall mean the volume-weighted
average pressure measured at the downstream static pressure tap of the meter at all Delivery
Points on acreage described in Schedule A of this Contract, calculated each Month by multiplying
the total daily volume for each day during the Month at each Delivery Point times the average
pressure for each corresponding day during such Month at such Delivery Point, summing the
resulting products for all such days and Delivery Points, and dividing the resulting sum by the
sum of such daily volumes. The “System Average Working Pressure” for the Non-Loco Hills Area
shall mean the volume-weighted average pressure measured at the downstream static pressure tap of
the meter at all Delivery Points on acreage described in Schedule B of this Contract, calculated
each Month by multiplying the total daily volume for each day during the Month at each Delivery
Point times the average pressure for each corresponding day during such Month at such Delivery
Point, summing the resulting products for all such days and Delivery Points, and dividing the
resulting sum by the sum of such daily volumes.

     (e) In the calculation of the System Average Working Pressure, Buyer may exclude any Day
during which a Force Majeure condition exists or there is any scheduled shutdown of Buyer’s
Facilities for maintenance; provided, however, for the purposes of this Paragraph 3, routine
maintenance and downtime associated with Buyer’s Loco Hills gathering system and associated
compressor stations shall not be considered Force Majeure incidents, and Days during which such
activities have occurred shall be included in the calculation of the System Average Working
Pressure in determining whether Buyer has exceeded Contract Pressure.

     (f) Within 30 days after the end of each Month, Buyer shall provide Seller an electronic
copy of all reports and calculations made in connection with the determination of System Average
Working Pressures and any Pressure Payment Penalties, together with all supporting data.

     4. QUANTITY.

     (a) Subject to the terms hereof, Seller shall deliver and Buyer shall purchase and take
Seller’s Gas, exercising commercially reasonable efforts to accept, process and market Gas for
resale and operate its facilities in an effort to maintain consistent takes of all quantities made
available by Seller during the term hereof. If Buyer takes less than the full quantities
available, subject to the terms hereof, Buyer will use commercially reasonable efforts to purchase
Gas from the lands covered by this Contract ratably with its purchases of similar Gas in each
common

- 3 -

 

gathering system or area in compliance with Buyer’s existing contracts and with applicable
laws and regulations, including ratable purchases from Buyer’s Affiliates. Should curtailment be
necessary, Buyer shall designate how much volume shall be curtailed. Seller shall then determine
which production shall undergo the curtailment.

	 	(i)	 	As of December 2006 and continuing each December thereafter for the term of
the Contract, Seller shall provide, in good faith, to Buyer with the following: 1) a
volume projection for the next two ensuing calendar years, such volume projection will
be exclusive of capital uplift volume and 2) Seller’s preliminary plans for capital
expenditures that are to be completed during the ensuing calendar year and that are
intended to increase or enhance production, provided that Buyer recognizes and
acknowledges that such information will be Seller’s good faith estimates only and that
Seller shall have no liability for any failure to achieve such projected production
volumes or expenditures. Such capital expenditures to include those for the drilling
of a new well, re-completion into a new formation, additions of pay zones in an
existing formation, work-overs, and new central delivery points. With such disclosure
of preliminary plans for capital expenditures, Seller shall provide Buyer with a
volume projection for the next ensuing calendar year. Such volume projection will be
inclusive of capital uplift volume.
	 
	 	(ii)	 	Commencing the first quarter 2007 and continuing quarterly thereafter for the
remaining term of this Contract, Seller and Buyer shall meet to confirm Seller’s plans
for capital expenditures to be completed during that calendar year. Likewise, at each
quarterly meeting, Buyer shall disclose Buyer’s (1) capital and maintenance program
contemplated on Buyer’s Facilities during that year, including that portion of Buyer’s
capital program pertinent to providing gathering and compression services for both then
existing volume and volume uplift attributable to Seller’s capital expenditures (if
any); and (2) schedule for maintenance of Buyer’s Facilities for the ensuing twelve
months, including any maintenance which will require a shut down of the Buyer’s
Facilities.

(b) In the event Buyer curtails or fails to take Seller’s production due to insufficient capacity
in Buyer’s facilities (other than capacity limitations caused by a Force Majeure event or any
scheduled

- 4 -

 

shut down of Buyer’s Facilities for maintenance), then the Base Volume (as defined
below) shall be reduced by the amount of Seller’s Gas which was curtailed or otherwise not taken
during such Month The amount of Gas curtailed or otherwise not taken by Buyer shall be estimated in good
faith by the parties based upon Seller’s production volumes during the period immediately prior to
the subject period. Buyer and Seller agree that for the purposes of this Paragraph 4(b), Buyer’s
failure to maintain System Average Working Pressures at or below the applicable Contract Pressure
specified in Paragraph 3.2(a), above, shall not constitute a curtailment of Seller’s production,
and that Seller’s sole remedy for exceeding the applicable Contract Pressure shall be the Pressure
Penalty Payment specified in Paragraph 3.2 (b) above.

(c) Seller may dispose of any Gas not taken by Buyer for any reason, including events of Force
Majeure, subject to Buyer’s right to resume purchases as provided herein. If Buyer does not take
Gas for 7 consecutive Days, Seller may secure a temporary market for a term of up to 60 days, and
Buyer may resume purchases only upon 30 Days advance written notice as of the beginning of a Month
following such term, unless otherwise agreed; provided, however, that this Paragraph (c) shall not
apply to any scheduled shut down of Buyer’s Facilities for annual maintenance.

(d) Seller will use commercially reasonable efforts to deliver Gas meeting the quality
requirements of Exhibit A Section F and to avoid delivery of Inferior Liquids as defined in
Exhibit A Section A(h). If the Gas at any Delivery Point becomes insufficient in volume, quality,
or pressure, Buyer may cease Gas takes at such Delivery Point for so long as the condition exists.
If Buyer fails to take or otherwise ceases taking Gas under this Paragraph 4(d) for 30
consecutive Days for reasons other than quality [Exhibit A Section F] or Force Majeure [Exhibit A
Section H], Seller may terminate this Contract with respect to the affected Delivery Points as to
the then productive zones upon 30 Days advance written notice to Buyer; provided that during the
notice period Buyer may resume consistent takes and purchases, and thereby avoid Contract
termination under Seller’s notice.

     5. PRICE.

     5.1 Consideration. As full consideration for the Gas and all its components delivered
by Seller and received by Buyer each Month, Buyer shall pay Seller:

(a) As to the first *** (***) Mcf per Day in the aggregate delivered under this
Contract each Month (the “Base Volume”):

- 5 -

 

(1) *** percent (***%) of the amount determined under
Paragraph 5.2 below for the sale of net Residue Gas allocated
to Seller’s Gas; and

(2) *** percent (***%) of the net proceeds determined under
Paragraph 5.3 below from the sale of any NGL’s saved and sold
in liquid form at Buyer’s Facilities and allocated to Seller’s
Gas.

(b) As to any incremental volume in excess of *** (***) Mcf per Day in the
aggregate delivered under this Contract each Month:

(1) *** percent (***%) of the amount determined under
Paragraph 5.2 below for the sale of Residue Gas allocated to
Seller’s Gas; and

(2) *** percent (***%) of the net proceeds determined
under Paragraph 5.3 below from the sale of any NGL’s saved and
sold in liquid form at Buyer’s Facilities and allocated to
Seller’s Gas.

Provided, that the total payment and consideration due Seller pursuant to this
Paragraph 5.1 shall be allocated to each Delivery Point as a weighted average for
the aggregate volumes purchased under this Contract.

No separate payment or value calculation is to be made under this Contract for
helium, sulfur, CO2, other non-hydrocarbons, or Inferior Liquids.

     5.2 Residue Gas Value. The net Residue Gas value will be determined by multiplying
the MMBtu’s of Residue Gas allocable to Seller, as determined in accordance with Paragraph 5.5
below, times the arithmetical average of the following two index prices per MMBtu published in
Inside F.E.R.C.’s Gas Market Report in its first publication of the Month in which the Gas is
delivered for “Prices of Spot Gas Delivered to Pipelines”: 1) El Paso – Permian Basin and 2)
Transwestern – Permian Basin. If the Index Price quotation is discontinued or materially
modified, Buyer and Seller will select another publication that enables calculation of an Index
Price closely comparable to that previously used. If a change in the Index Price becomes
necessary, Buyer will so inform Seller by written notice, setting forth its proposed changes.
Should the parties fail to agree upon a successor publication within a timely fashion, the price
utilized shall be Buyer’s plant(s) weighted average price of sales for the Month for which pricing
is being determined.

     5.3 NGL Value. The net value of any recovered NGLs attributable to Seller will be
determined by multiplying the quantity of each NGL component attributable to Seller’s Gas, as
determined in accordance with Paragraph 5.5 below, by the average price per gallon for each NGL

- 6 -

 

component f.o.b. Buyer’s plant or plants. “Average price per gallon for each NGL component f.o.b.
Buyer’s plant or plants” as to each NGL component will mean the simple average of the midpoint
of the daily high/low spot price for (i) ethane in E-P mix, (ii) Non-TET propane, (iii) Non-TET
isobutane, (iv) Non-TET normal butane, and (v) Non-TET natural gasoline (pentanes and heavier)
during the Month as reported for Mont Belvieu, Texas by the Oil Price Information Service (or in
its absence, a comparable successor publication mutually agreed to by Buyer and Seller) less a
transportation, fractionation, and storage (“TF&S”)
fee of 5.0¢ per gallon. As of the beginning
of each calendar year beginning with 2008, Buyer will adjust the current year’s TF&S fee upward or
downward as follows, but it will never be less than the initial fee. Buyer will adjust (i) 55% of
the TF&S fee by an amount equal to the annual percentage of change in the preliminary estimate of
the implicit price deflator, seasonally adjusted, for the gross domestic product (“GDP”) as
computed and most recently published by the U.S. Department of Commerce, rounded to the nearest
100th cent, or in its absence, a similar successor adjustment factor mutually agreed to
by Buyer and Seller, and (ii) 45% of the TF&S fee by the percentage difference between the yearly
average of the previous year’s Monthly Index Prices defined in Section 5.2 above and those for the
second previous year. Should the parties fail to agree upon a successor publication within a
timely fashion, the price utilized shall be Buyer’s plant(s) weighted average price of sales for
the month for which pricing is being determined.

     5.4 Low Volume Delivery Points. If the total volume made available to Buyer at any
Delivery Point is less than three hundred (300) Mcf per Month for three consecutive Months, Seller
will thereafter pay Buyer a low volume fee of $250.00 per Month per low volume Delivery Point.
The low volume fee will remain in effect for each Month until the quantity made available to the
Delivery Point is again at least three hundred (300) Mcf per Month. Buyer may deduct this fee
from any proceeds payable to Seller or may invoice Seller for the amount due, with such invoice to
be paid within 30 days of the invoice date.

     5.5 Allocation of Residue Gas and NGLs. Subject to the terms hereof, Buyer will
determine the Residue Gas and NGLs attributable to Seller using the following definitions and
procedures. Additional definitions are in Section A of Exhibit A.

     a. Field Compression. All compression downstream from the Delivery
Points, including that adjacent to the plant inlet, that compresses Gas to the plant
inlet pressure.

- 7 -

 

     b. Plant Inlet Gallons. The quantity of each NGL component attributable
to Seller delivered to the plant inlet will be determined by multiplying the gallons
of
each component contained in the Gas delivered by Seller at each Delivery Point by the
applicable percentage as follows:

	 	 	 
	Pressure	 	Percentage
	Low Pressure

	 	94%

     c. NGLs Attributable to Seller. The quantity of each NGL component
attributable to Seller’s Gas will be determined by multiplying Seller’s Plant Inlet
Gallons times the following fixed recovery percentages:

	 	 	 
	Ethane
	 	85%
	Propane
	 	90%
	Iso & Normal Butanes
	 	97%
	Pentanes & Heavier
	 	99%

     d. Residue Gas Attributable to Seller. The MMBtus of Residue Gas
attributable to Seller will be the sum of the MMBtus of methane and heavier
hydrocarbons contained in the Gas delivered at the Delivery Points by Seller, less
the MMBtus contained in the NGL gallons allocated to Seller’s Gas determined under
Paragraph 5.5(c) above, less the fixed percentage below of the MMBtus delivered at
each Delivery Point for field compression and plant fuel, losses, and
unaccountables:

	 	 	 
	Low Pressure
	 	12%

Whenever Force Majeure prevents normal gathering and processing operations for
Seller’s Gas, fixed recovery percentages will not apply, and Seller’s attributable
NGL gallons and Residue Gas will be based on Seller’s pro rata share of actual
gathering and processing results during those periods based on Gas compositions,
volumes from each common source, and an equitable distribution among suppliers of
fuel, losses, and unaccountables, in a manner similar to that used for Buyer’s
purchase contracts that call for allocations based on actual results, consistently
applied in good faith. Buyer will include the adjusted overall Monthly recoveries
in its Monthly Gas statement to Seller.

     e. Revenue from Inferior Liquids will be retained by Buyer to defray costs of
treating and handling; Buyer will not allocate or pay for Inferior Liquids.

     5.6 Minimum Margin. If the pricing terms of this Contract, other than this
Paragraph 5.6, and prior to consideration of any Pressure Payment Penalty, would result in a gross
margin to Buyer associated with the purchase, gathering, processing, and resale of Gas sold that
is less than

- 8 -

 

$*** per MMBtu for all of Seller’s Gas processed and sold, Buyer shall be entitled to
recover an amount hereunder sufficient to allow it a minimum gross margin of $*** per MMBtu
(“Minimum Margin”). The Minimum Margin is calculated as the gross NGL value plus the gross Residue
Gas value to Buyer under the terms of this Contract less the payment otherwise due Seller under this
Contract. The Minimum Margin shall be adjusted at the beginning of each calendar year beginning
with 2008 by an amount equal to the annual percentage change in the GDP inflation factor as
defined in Paragraph 5.3 above or any replacement for it. To collect the Minimum Margin, Buyer
will invoice Seller for the amounts due each Month, as applicable, showing all calculations and
enclosing all supporting documentation, with such invoice to be paid by Seller within 30 days of
receipt.

     6. TERM. This Contract shall be in force for a primary term expiring on
October 31, 2016, and from year to year thereafter until canceled by either party as of the end of
the primary term or any anniversary thereafter by giving the other party at least 60 Days’ advance
written notice of termination.

     7. ADDRESSES AND NOTICES. Either party may give notices to the other party
or parties by first class mail postage prepaid, by overnight delivery service, or by facsimile with
receipt confirmed at the following addresses or other addresses furnished by a party by written
notice. Payments due Seller hereunder shall be made at the address indicated below or such other
address furnished by Seller by written notice.

capitalized, the following terms will have meanings as follows:

a. Affiliate – a company (i) in which a party owns directly or indirectly 50% or more of
the issued and outstanding voting stock or other equity interests; (ii) which owns directly or
indirectly 50% or more of the issued and outstanding voting stock or equity interests of the party,
and (iii) in which a company described in (ii) owns, directly or indirectly, 50% or more of the
issued and outstanding voting stock or other equity interests.

b. Btu – British thermal unit, or the quantity of heat required to raise the temperature of
1 pound of water 1o F. at a starting temperature of 58.5o F. MMBtu — one million Btus.

c. Buyer’s Facilities – the gas delivered by Seller will be gathered in gathering systems
and may be redelivered to a gas processing plant or plants for the removal of NGLs together with
gas produced from other properties. The gathering systems and plant or plants, or successor
facilities, are “Buyer’s Facilities” whether owned by buyer, an affiliate of Buyer, or an
unaffiliated third party. No facilities downstream of the processing plant or plants other than
short connecting lines to transmission lines are included in “Buyer’s Facilities.”

d. Day or day – a period of 24 consecutive hours commencing at 12:01 a.m.

remaining after processing, and hydrocarbon gas resold by Buyer without first being processed.

q. TET – price quotes for NGL on the Texas Eastern Products Pipeline Company, LLC system.

r. TF&S – NGL transportation, fractionation, and storage, see Section 5.3.

B. DELIVERY DATE; COMPRESSION

B.1 Connected Sources Delivery Date. As to committed sources of production from
Seller already connected to Buyer’s Facilities, deliveries under this Contract will commence as of
November 1, 2006.

B.2 Additional Sources. As to sources not yet connected, Seller will commence and complete
with due diligence the construction of the facilities necessary to enable Seller to deliver the
committed gas at the Delivery Points and Buyer will cause prompt commencement and complete with due
diligence the construction of the facilities necessary and economically feasible to enable Buyer or
its gas gathering contractor to receive deliveries of gas at the Delivery Points. If Buyer
determines it is not profitable to construct the facilities, Seller will have the option to
construct facilities necessary to deliver gas into Buyer’s then existing facilities. If neither
Buyer nor Seller elect to construct the necessary facilities, either party may cancel this Contract
as to the affected gas upon 15 Days advance written notice to the other.

 

 

B.3 Delivery Rates. Seller will have agents or employees available at all reasonable times
to receive advice and directions from Buyer for changes in the rates of delivery of gas as required
from time to time.

B.4 Options to Compress. If Seller’s wells become incapable of delivering gas into Buyer’s
Facilities, neither party will be obligated to compress, but either party will have the option to
do so. If neither party elects to compress within a reasonable time after the need for compression
appears, Buyer upon written request of Seller will either arrange promptly to provide compression
or as Seller’s sole remedy, release the affected gas sources as to the then-producing formations
from commitment under this Contract.

C. RESERVATIONS OF SELLER

C.1 Reservations. Seller reserves the following rights with respect to its interests
in the oil and gas properties committed by Seller to Buyer under this Contract together with
sufficient gas to satisfy those rights:

a. To operate Seller’s oil and gas properties free from control by Buyer as Seller in Seller’s sole
discretion deems advisable, including without limitation the right, but never the obligation, to
drill new wells, to repair and rework old wells, renew or extend, in whole or in part, any oil and
gas lease covering any of the oil and gas properties, and to abandon any well or surrender any such
oil and gas lease, in whole or in part, when no longer deemed by Seller to be capable of producing
gas in paying quantities under normal methods of operation.

b. To use gas for developing and operating Seller’s oil and gas properties committed under this
Contract and to fulfill obligations to Seller’s lessors for those properties.

c. To pool, combine, and unitize any of Seller’s oil and gas properties with other properties in
the same field, and to alter pooling, combinations, or units, in which event this Contract will
cover Seller’s allocated interest in unitized production insofar as that interest is attributable
to the oil and gas properties committed under this Contract, and the description of property
committed will be considered to have been amended accordingly.

C.2 Exception. Notwithstanding Section C.1, Seller will not engage in any operation,
including without limitation reinjection, recycling, or curtailment, that would materially reduce
the amount of gas available for sale to Buyer except upon 120 Days advance written notice to Buyer,
or as much advance notice as is feasible under the circumstances. Buyer will own and be entitled to collect
and pay Seller for any NGLs that condense or are manufactured from gas during any of Seller’s
operations with respect to Seller’s gas committed under this Contract, excluding crude oil and
distillate recovered from gas by conventional type mechanical separation equipment and not
delivered to Buyer.

D. METERING AND MEASUREMENT

D.1 Buyer to Install Meters. Buyer will own, maintain and operate orifice meters or
other measuring devices of standard make at or near the Delivery Points. Except as otherwise
specifically provided to the contrary in this Section D, orifice meters or other measurement
devices will be installed and volumes computed in accordance with accepted industry practice. Buyer
may re-use metering equipment not meeting current standards but meeting 1985 or later published
standards for gas sources not expected to deliver in excess of 100 Mcf per Day. A party providing
compression facilities will also provide sufficient pulsation dampening equipment to prevent
pulsation from affecting measurement at the Delivery Points. Electronic recording devices may be
used. Seller will have access to Buyer’s metering equipment at reasonable hours, but only Buyer
will calibrate, adjust, operate, and maintain it.

D.2 Unit of Volume. The unit of volume will be one cubic foot of gas at a base temperature
of 60°F and at a pressure base of 14.65 psia. Computations of volumes will follow industry
accepted practice.

D.3 Pressure, Temperature. Buyer may measure the atmospheric pressure or may assume the
atmospheric pressure to be 13.2 psia. Buyer may determine the gas temperature by using a recording
thermometer; otherwise, the temperature will be assumed to be 60°F.

D.4 Check Meters. Seller may install, maintain, and operate in accordance with accepted
industry practice at its own expense pressure regulators and check measuring equipment of standard
make using separate taps. Check meters shall not interfere with operation of Buyer’s equipment.
Buyer will have access to Seller’s check measuring equipment at all reasonable hours, but only
Seller will calibrate, adjust, operate, and maintain it.

D.5 Meter Tests. Buyer will verify the accuracy of Buyer’s measuring equipment, and
Seller or its lease operator will verify the accuracy of any check measuring equipment on the
following basis:

	 	 	 	 	 
	Mcf/Day	 	Calibration	 	Gas Analysis
	Meters
3 1000
	 	Quarterly
	 	Quarterly
	Meters 100 to 999
	 	Semi-Annual
	 	Semi-Annual
	Meters 0 to 99
	 	Annually
	 	Annually

- A 2 -

 

Buyer and Seller will cooperate to secure a prompt verification of the accuracy of the equipment.
If either at any time observes a variation between the delivery meter and the check meter, it will
promptly notify the other, and both will then cooperate to secure an immediate verification of the
accuracy of the equipment. Buyer will give Seller reasonable advance notice of the time of all tests and
calibrations of meters and of sampling for determinations of gas composition and quality, so that
the Seller may have representatives present to witness tests and sampling or make joint tests and
obtain samples with its own equipment. Seller will give reasonable advance notice to Buyer of
the time of tests and calibrations of any check meters and of any sampling by Seller for
determination of gas composition and quality. Seller may request sampling and analysis of Buyer’s
measuring equipment more frequently than quarterly. If Seller so requests, Seller must be
present when the special sample is captured and authorize the test in writing. If new sample
differs materially (i.e. the stated methane or any NGL component’s result changes by more than 2%
from the most previous test), Buyer will absorb the cost of the sample and analysis. If the new
sample results do not differ materially from the most previous test , Seller will pay Buyer a
$250.00 sampling and testing fee per test within 30 Days following receipt of Buyer’s invoice.

D.6 Correction of Errors. If at any time any of the measuring or testing equipment is
found to be out of service or registering inaccurately in any percentage, it will be adjusted
promptly to read accurately within the limits prescribed by the manufacturer. If any measuring
equipment is found to be inaccurate or out of service by an amount exceeding the greater of (i) 2.0
percent at a recording corresponding to the average hourly rate of flow for the period since the
last test, or (ii) 100 Mcf per Month, previous readings will be corrected to zero error for any
known or agreed period. The volume of gas delivered during that period will be estimated by the
first feasible of the following methods:

(i) Using the data recorded by any check measuring equipment if registering accurately;

(ii) Correcting the error if the percentage of error is ascertainable by calibration, test,
or mathematical calculation; or

(iii) Using deliveries under similar conditions during a period when the equipment was
registering accurately.

No adjustment will be made for inaccuracies unless they exceed the greater of (i) 2.0 percent of
affected volumes, or (ii) 100 Mcf per Month.

D.7 Meter Records. The parties will preserve for a period of at least two years all test
data, charts and similar measurement records. The parties will raise metering questions as soon as
practicable after the time of production. No party will have any obligation to preserve metering
records for more than two years except to the extent that a metering question has been raised in
writing and remains unresolved.

E. DETERMINATION OF GAS

COMPOSITION, GRAVITY, AND

HEATING VALUE

     Buyer will obtain a representative sample of Seller’s Gas delivered at each Delivery
Point on the following basis, or more often as Buyer deems advisable; or Buyer may, in its sole
discretion, use continuous samplers.

	 	 	 	 	 
	Mcf/Day	 	Calibration	 	Gas Analysis
	Meters 3 1000
	 	Quarterly
	 	Quarterly
	Meters 100 to 999
	 	Semi-Annual
	 	Semi-Annual
	Meters 0 to 99
	 	Annually
	 	Annually

By chromatography or other accepted method in the industry, Buyer will determine the composition,
gravity and gross heating value of the hydrocarbon components of Seller’s gas in Btu per cubic foot
on a dry basis at standard conditions, then adjusting the result for the water vapor content of the
gas (by either the volume or Btu content method), using an industry accepted practice. No heating
value will be credited for Btus in H2S or other non-hydrocarbon components. The first
determination of Btu content for Seller’s deliveries will be made within a reasonable time after
deliveries of gas begin. If continuous samplers or on-line chromatography are used, the
determinations will apply to the gas delivered while the sampler was installed. If not, the
determination will apply until the first Day of the Month following the next determination

F. QUALITY OF GAS

F.1 Quality Specifications. The gas shall be merchantable natural gas, at all times
complying with the following quality requirements. The gas shall be commercially free of crude
oil, water in the liquid phase, brine, air, dust, gums, gum-forming constituents,

- A 3 -

 

bacteria, and
other objectionable liquids and solids, and not contain more than:

a. 1/4 grain of H2S per 100 cubic feet.

b. Five grains of total sulfur nor more than one grain of mercaptan per 100 cubic feet.

c. Two mole percent of carbon dioxide.

d. Three mole percent of nitrogen.

e. Ten parts per million by volume of oxygen, and not have been subjected to any treatment or
process that permits or causes the admission of oxygen, that dilutes the gas, or otherwise causes
it to fail to meet these quality specifications.
 

f. Five mole percent of combined carbon dioxide, nitrogen, and oxygen.

The gas shall:

g. Not exceed 120°F in temperature at the Delivery Point.

h. Have a total heating value of at least 1100 Btus per cubic foot.

i. If a third party pipeline receiving the gas delivered has more stringent quality specifications
than those stated above, Seller’s gas shall conform to the more stringent pipeline quality
standard.

F.2 Quality Tests. Buyer will make determinations of conformity of the gas with the above
specifications using procedures generally accepted in the gas industry as often as Buyer reasonably
deems necessary. If in the lease operator’s judgment the result of any test or determination is
inaccurate, Buyer upon request will again conduct the questioned test or determination. The costs
of the additional test or determination will be borne by Seller unless it shows the original test
or determination to have been materially inaccurate.

F.3 Separation Equipment. Seller will employ only conventional mechanical separation
equipment at all production sites covered by this Contract. Low temperature, absorption, and
similar separation facilities are not considered conventional mechanical separation equipment.
Except for liquids removed through operation of conventional mechanical separators and except for
removal of substances as required to enable Seller to comply with this Section F, no components of
the gas will be removed prior to delivery to Buyer.

F.4 Rights as to Off Specification Gas. If any of the gas delivered by Seller fails to
meet the quality specifications stated in this Section F, Buyer may at its option accept delivery
of and pay for the gas or discontinue or curtail taking of gas at any Delivery Point whenever its
quality does not conform to the quality specifications. If Buyer accepts delivery of off
specification gas from Seller or incurs costs relating to inferior gas quality in its gathering
system, Buyer will deduct from the proceeds otherwise payable a fee of $0.05/Mcf plus $0.02 times
the total mole percent, and any fraction of a mole percent, of H2S and CO2
times the Mcf quantity delivered at the affected off quality Delivery Points. If Buyer rejects
delivery, Buyer’s notice to that effect will terminate this Contract with respect to the off
specification gas named in the notice. If Buyer accepts delivery of gas from Seller that is off
specification for nitrogen content, Buyer will deduct a fee of $0.06/Mcf for each mole percent,
and each fraction of a mole percent, of nitrogen content over the allowed nitrogen specification
for all volumes delivered by Seller at the affected excess nitrogen Delivery Points. As of the
beginning of each calendar year beginning with 2007, Buyer will adjust the current year’s treating
fees upward or downward as follows, but they will never be less than the initial fees. The
current year’s treating fee shall be adjusted by an amount equal to the annual percentage change
in the preliminary estimate of the implicit price deflator, seasonally adjusted, for the gross
domestic product (“GDP”) as computed and most recently published by the U.S. Department of
Commerce, rounded to the nearest 100th cent, or in its absence, a similar successor
adjustment factor mutually agreed upon by Buyer and Seller.

G. BILLING AND PAYMENT

G.1 Statement and Payment Date. Buyer will render to Seller on or before the last Day
of each Month a statement showing the volume of gas delivered by Seller during the preceding Month.
Buyer will make payment to Seller on or before the last Day of each Month for all gas delivered
during the preceding Month. As between the parties, amounts unpaid hereunder beyond the applicable
due date will carry simple interest at the lower of 6% per annum or the maximum lawful interest
rate; provided that no interest will accrue as to Monthly principal amounts of less than $1,000 due
for less than one year when paid. The parties waive any rights to differing interest rates.
Except as limited in Section G.2 below, Buyer may recover any overpayments or collect any
undisputed amounts due from Seller to Buyer for any reason at any time under this Contract by
deducting them from proceeds payable to Seller.

G.2 Audit Rights; Time Limit to Assert Claims.

a. Each party will have the right during reasonable business hours to examine the books, records
and charts of the other party to the extent necessary to verify performance of this Contract and
the accuracy of any payment, statement, charge or computation upon execution of a reasonable
confidentiality agreement. If any audit examination or

- A 4 -

 

review of the party’s own records reveals an inaccuracy in any payment, the appropriate
adjustment will promptly be made.

b. No adjustment for any billing or payment shall be made, and payments shall be final after
the lapse of two years from payment except as to matters that either party has noted in a
specific written objection to the other party during the two year period, unless within the two
year period Buyer has made the appropriate correction. However, Seller’s responsibilities for
severance taxes and third party liabilities and related interest are not affected by this
subsection.

c. No party will have any right to recoup or recover prior overpayments or underpayments that
result from errors that occur in spite of good faith performance if the amounts involved do not
exceed $10/Month/meter. Either party may require prospective correction of such errors.

H. FORCE MAJEURE

H.1 Suspension of Performance. If either party is rendered unable, wholly or in part,
by Force Majeure to carry out its obligations under this Contract, other than to make payments due,
the obligations of that party, so far as they are affected by Force Majeure, will be suspended
during the continuance of any inability so caused, but for no longer period.

H.2 Force Majeure Definition. “Force Majeure” means acts of God, strikes, lockouts or
other industrial disturbances, acts of the public enemy, wars, blockades, insurrections, riots,
epidemics, landslides, lightning, earthquakes, storms, floods, washouts, arrests and restraints of
governments and people, civil disturbances, fires, explosions, breakage or accidents and other
causes, whether of the kind listed above or otherwise, not within the control of the party claiming
suspension and which by the exercise of reasonable diligence the party required to perform is
unable to prevent or overcome.

H.3 Labor Matters Exception. The settlement of strikes or lockouts will be entirely within
the discretion of the party having the difficulty, and settlement of strikes, lockouts, or other
labor disturbances when that course is considered inadvisable is not required.

I. WARRANTY OF TITLE 

     Seller warrants that it has good title and processing rights to the gas delivered, free
and clear of any and all liens, encumbrances, and claims, and that Seller has good right and lawful
authority to sell the same. Seller grants to Buyer the right to process Seller’s gas for
extraction of NGLs and other valuable components. If Seller’s title or right to receive any
payment is questioned or involved in litigation, Buyer will have the right to withhold the
contested payment without interest until title information is received, during the litigation,
until the title or right to receive the questioned payments is freed from question, or until Seller
furnishes security for repayment reasonably acceptable to Buyer. Without impairment of Seller’s
warranty of title to gas and gas processing rights, if Seller owns or controls less than full title
to the gas delivered, payments will be made only in the proportion that Seller’s interest bears to
the entire title to the gas.

J. ROYALTY AND OTHER INTERESTS

     Seller is responsible for all payments to the owners of all working interests, mineral
interests, royalties, overriding royalties, bonus payments, production payments and the like.
Buyer assumes no liability to Seller’s working or mineral interest, royalty, or other interest
owners under this Contract.

K. SEVERANCE AND SIMILAR TAXES

K.1 Included in Price. Reimbursement to Seller for Seller’s full liability for
severance and similar taxes levied upon Seller’s gas production is included in the prices payable
under this Contract, regardless of whether some included interests may be exempt from taxation.

K.2 Tax Responsibilities and Disbursements. Seller shall bear, and unless otherwise
required by law, will pay to taxing authorities all severance, production, excise, sales, gross
receipts, occupation, and other taxes imposed upon Seller with respect to the Gas on or prior to
delivery to Buyer. Buyer will bear and pay all taxes imposed upon Buyer with respect to the Gas
after delivery to Buyer; however, Buyer will charge to Seller and deduct from the proceeds
otherwise payable Seller’s pro rata share of taxes paid by Buyer and levied upon the gathering,
treatment, processing, or sale of the Gas and related products, including without limitation the
New Mexico Gas Processors Tax, but excluding ad valorem taxes and taxes based on Buyer’s net income
that are to be borne by Buyer.

L. INDEMNIFICATION AND RESPONSIBILITY FOR INJURY OR DAMAGE

L.1 Title, Royalty, and Severance Taxes. SELLER RELEASES AND AGREES TO DEFEND, INDEMNIFY,
AND SAVE BUYER,

- A 5 -

 

ITS AFFILIATES, AND THEIR OFFICERS, EMPLOYEES, AND AGENTS (“BUYER
INDEMNITEES”) HARMLESS FROM AND AGAINST ALL CLAIMS, CAUSES OF ACTION, LIABILITIES, AND COSTS
(INCLUDING REASONABLE ATTORNEYS’ FEES AND COSTS OF INVESTIGATION AND DEFENSE) RELATING TO (a)
SELLER’S TITLE TO GAS AND GAS PROCESSING RIGHTS, (b) PAYMENTS FOR WORKING, MINERAL, ROYALTY AND
OVERRIDING ROYALTY AND OTHER INTERESTS, AND (c) SALES, SEVERANCE, AND SIMILAR TAXES, THAT ARE THE
RESPONSIBILITY OF SELLER UNDER SECTIONS I, J, AND K ABOVE.

L.2 Responsibility for Injury or Damage. As between the parties, Seller will be in control
and possession of the gas deliverable hereunder and responsible for any injury or damage relating
to handling or delivery of gas until the gas has been delivered to Buyer at the Delivery Points;
after delivery, Buyer will be deemed to be in exclusive control and possession and responsible for
any injury or damage relating to handling or gathering of gas. THE PARTY HAVING RESPONSIBILITY
UNDER THE PRECEDING SENTENCE SHALL RELEASE, DEFEND, INDEMNIFY, AND HOLD THE OTHER PARTY, ITS
AFFILIATES, AND THEIR OFFICERS, EMPLOYEES, AND AGENTS HARMLESS FROM AND AGAINST ALL CLAIMS, CAUSES
OF ACTION, LIABILITIES, AND COSTS (INCLUDING REASONABLE ATTORNEYS’ FEES AND COSTS OF INVESTIGATION
AND DEFENSE) ARISING FROM ACTUAL AND ALLEGED LOSS OF GAS, PERSONAL INJURY, DEATH, AND DAMAGE
ATTRIBUTABLE TO CLAIMS ARISING ENTIRELY DURING SUCH PARTY’S CONTROL AND RESPONSIBILITY PROVIDED
ABOVE; PROVIDED THAT NEITHER PARTY WILL BE INDEMNIFIED FOR ITS OWN NEGLIGENCE OR THAT OF ITS
AGENTS, SERVANTS, OR EMPLOYEES.

M. RIGHT OF WAY

     Insofar as Seller’s lease or leases permit and insofar as Seller or its lease operator
may have any rights however derived (whether pursuant to oil and gas lease, easement, governmental
agency order, regulation, statute, or otherwise), Seller grants to Buyer and Buyer’s gas gathering
contractor, if any, and their assignees the right of free entry and the right, at Buyer’s sole risk
and cost to lay and maintain pipelines, meters, and any equipment on the lands or leases subject to
this Contract as reasonably necessary in connection with the purchase or handling of Seller’s gas
and at locations acceptable to Seller. Upon written request from Buyer to Seller, Seller shall
grant, in writing, to Buyer or Buyer’s designee, recordable rights of ingress and egress as
necessary or appropriate for the purposes of complying with the terms of this Contract. All
pipelines, meters, and other equipment placed by Buyer or Buyer’s contractors on the lands and
leases will remain the property of the owner and may be removed by the owner at any time. Without
limitation, Buyer or its gathering contractor may disconnect and remove measurement and other
facilities from any Delivery Point due to low volume, quality, term expiration, or other cause.

     Upon the termination of this Contract for any reason the rights granted by this Section M
shall be terminated without notice and Buyer will immediately remove any of such above ground
equipment from such lands and leases and take all other actions to restore such lands to the
original state prior to Buyer’s actions under this Contract, including the removal of underground
equipment, to the extent required by applicable law or regulation or any third party obligations
applicable to the lands and leases.

N. ASSIGNMENT

N.1 Binding on Assignees. Either party may assign this Contract. This Contract is
binding upon and inures to the benefit of the successors, assigns, heirs, personal representatives,
and representatives in bankruptcy of the parties, and, subject to any prior dedications by the
assignee, shall be binding upon any purchaser of Buyer’s Facilities and upon any purchaser of the
properties of Seller subject to this Contract. Nothing contained in this Section will prevent
either party from mortgaging its rights as security for its indebtedness, but security is
subordinate to the parties’ rights and obligations under this Contract.

N.2 Notice of Assignment. Any assignment or sublease by Seller of any oil and gas
properties or any gas rights contracted to Buyer will be made expressly subject to the provisions
of this Contract. No transfer of or succession to the interest of Seller, however

- A 6 -

 

made, will bind
Buyer unless and until the original instrument or other proper proof that the claimant is legally
entitled to an interest has been furnished to Buyer at its Division
Order address noted in the Notices Section or subsequent address.

O. MISCELLANEOUS PROVISIONS

O.1 Governing Law. THIS CONTRACT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS, without reference to those that might refer to the laws of
another state.

O.2 Default and Nonwaiver. A waiver by a party of any one or more defaults by the other in
the performance of any provisions of this Contract will not operate as a waiver of any future
default or defaults, whether of a like or different character.

O.3 Counterparts. This Contract may be executed in any number of counterparts, all of
which will be considered together as one instrument, and this Contract will be binding upon all
parties executing it, whether or not executed by all parties owning an interest in the producing
sources affected by this Contract. Signed copies of this Contract and facsimiles of it shall have
the same force and effect as originals.

O.4 Negotiations; Entire Agreement; Amendment; No Third Party Beneficiaries. The language
of this Contract shall not be construed in favor of or against either Buyer or Seller, but shall be
construed as if the language were drafted mutually by both parties. This Contract constitutes the
final and complete agreement between the parties. There are no oral promises, prior agreements,
understandings, obligations, warranties, or representations between the parties relating to this
Contract other than those set forth herein. All waivers, modifications, amendments, and changes to
this Contract shall be in writing and signed by the authorized representatives of the parties. The
relations between the parties are those of independent contractors; this Contract creates no joint
venture, partnership, association, other special relationship, or fiduciary obligations. There are
no third party beneficiaries of Buyer’s sales contracts or of this Contract.

O.5 Ratification and Third Party Gas. Notwithstanding anything contained herein to
the contrary, Buyer has no duty under this Contract to purchase or handle gas attributable to
production from interests of third parties that has been purchased by Seller for resale, except
that Buyer will purchase Other WI Gas. “Other WI Gas” means gas attributable to working and
mineral interests owned by third parties in wells operated by Seller that are subject to this
Contract that Seller has the right to market under an operating agreement. If Buyer requests in
writing that Seller obtain ratification of this Contract from owners of Other WI Gas, Seller will
use all reasonable commercial efforts to cause those Other WI Gas owners to execute and deliver to
Buyer an instrument prepared by Buyer for the purpose of ratifying and adopting this Contract with
respect to the owner’s Other WI Gas, and the ratifying owner will become a party to this Contract
with like force and effect as though the Other WI owner had executed this Contract as amended as of
the time of the ratification, and all of the terms and provisions of this Contract as then amended
will become binding upon Buyer and the ratifying owner.

O.6 Compliance with Laws and Regulations. This Contract is subject to all valid statutes
and rules and regulations of any duly constituted federal or state authority or regulatory body
having jurisdiction. Neither party will be in default as a result of compliance with laws and
regulations.

O.7 Fees and Costs; Damages. If a breach occurs, the parties are entitled to recover as
their sole and exclusive damages for breach of the price and quantity obligations under this
Contract the price for gas taken by Buyer in the case of Seller and the lost margin less avoided
costs in the case of Buyer. If mediation or arbitration is necessary to resolve a dispute other
than one arising under the indemnification obligations of this Contract, each party agrees to bear
its own attorneys’ fees and costs of investigation and defense, and each party waives any right to
recover those fees and costs from the other party or parties.

O.8 Mutual Waiver of Certain Remedies. Except as to the parties’ indemnification
obligations, NEITHER PARTY SHALL BE LIABLE OR OTHERWISE RESPONSIBLE TO THE OTHER FOR CONSEQUENTIAL
OR INCIDENTAL DAMAGES, FOR LOST PRODUCTION, OR FOR PUNITIVE DAMAGES AS TO ANY ACTION OR OMISSION,
WHETHER CHARACTERIZED AS A CONTRACT BREACH OR TORT, THAT ARISES OUT OF OR RELATES TO THIS CONTRACT
OR ITS PERFORMANCE OR NONPERFORMANCE.

O.9 Recording Memorandum. Upon request by either party, the parties shall execute and
place of record a reasonable short form recording memorandum of this Contract and any amendment.

- A 7 -

 

O.10 Waiver of Jury Trial. The parties hereby waive a right to a trial by jury.
