respects, as the case may be, as of such earlier date.

               SECTION 8. Continuing Effect of the Credit Agreement. This Amendment shall not
constitute an amendment or waiver of or consent to any provision of the Credit Agreement not
expressly referred to herein and shall not be construed as an amendment, waiver or consent to any
action on the part of the Borrower that would require an amendment, waiver or consent of the
Administrative Agent or the Lenders except as expressly stated herein. Except as expressly amended

CREDIT AGREEMENT

     This CREDIT AGREEMENT is entered into as of May 11, 2005, among BOIS D’ARC ENERGY, INC., a
Nevada corporation (“Borrower”), each lender from time to time party hereto (collectively,
the “Lenders” and each individually, a “Lender”), THE BANK OF NOVA SCOTIA, as
Administrative Agent and Issuing Bank, CALYON NEW YORK BRANCH, as syndication agent, and AMSOUTH
BANK, as documentation agent.

PRELIMINARY STATEMENTS

     Borrower desires to obtain commitments from the Lenders pursuant to which Loans will be made
by the Lenders to the Borrower from time to time prior to the Maturity Date and Letters of Credit
will be issued by the Issuing Bank for the account of the Borrower from time to time prior to the
Letter of Credit Availability Expiration Date in accordance with and subject to the terms and
conditions of this Agreement and the other documents executed in connection therewith.

     The Administrative Agent, the Lenders and the Issuing Bank are willing, on the terms and
subject to the conditions hereinafter set forth (including Article IV), to make available
the commitments and make such Loans to the Borrower and issue and participate in such Letters of
Credit for the account of the Borrower.

     It is in the best interest of each of the Guarantors to execute and deliver a Guaranty as each
Guarantor will receive substantial benefits as a result of the Borrower entering into the borrowing
base, revolving credit facility with the Lenders.

     In consideration of the mutual covenants and agreements herein contained, the parties hereto
covenant and agree as follows:

ARTICLE I.

DEFINITIONS AND ACCOUNTING TERMS

     SECTION 1.1 Defined Terms. As used in this Agreement, the following terms shall have the
meanings set forth below:

     “Adjusted LIBO Rate” means, with respect to each particular Borrowing comprised of
LIBO Rate Loans and the associated LIBO Rate and Reserve Percentage, the rate per annum calculated
by the Administrative Agent (rounded upwards, if necessary, to the next higher 1/100%) determined
on a daily basis pursuant to the following formula:

	 	 	 	 	 	 	 	 	 
	 
	 	Adjusted LIBO Rate
	 	=
	 	LIBO Rate
	 	 
	 
	 	 	 	 	 	 	 	 
	 
	 	 	 	 	 	(1 – Reserve Percentage)	 	 

     “Administrative Agent” means The Bank of Nova Scotia in its capacity as administrative
agent under any of the Loan Documents, or any successor administrative agent.

     “Administrative Agent’s Office” means the Administrative Agent’s address and, as
appropriate, account as set forth on Schedule 10.2, or such other address or account as the

 

 

Administrative Agent may from time to time designate to the Borrower, the Issuing Bank, and the
Lenders.

     “Affiliate” means, as to any Person, any other Person directly or indirectly
controlling, controlled by, or under direct or indirect common control with, such Person. A Person
shall be deemed to be “controlled by” any other Person if such other Person possesses, directly or
indirectly, the power (a) to vote 10% or more of the securities (on a fully diluted basis) having
ordinary voting power for the election of directors or managing general partners or managing
members; or (b) to direct or cause the direction of the management and policies of such Person
whether by contract or otherwise.

     “Agent and Arranger Fee Letter” has the meaning set forth in Section 2.10(b).

     “Agent-Related Persons” means the Administrative Agent (including any successor
administrative agent), together with its Affiliates (including, in the case of Scotia Capital in
its capacity as the Administrative Agent, the Issuing Bank and the Arranger), and the officers,
directors, employees, agents and attorneys-in-fact of such Persons and Affiliates.

     “Aggregate Commitments” means, as of any date, the sum of the Commitments of all the
Lenders.

     “Agreement” means this Credit Agreement, as amended, restated, supplemented or
otherwise modified from time to time.

     “Arranger” means The Bank of Nova Scotia in its capacity as sole lead arranger.

     “Attorney Costs” means and includes all reasonable fees, expenses, costs and
disbursements of, for or on any law firm or other external counsel.

     “Attributable Indebtedness” means, on any date, (a) in respect of any capital lease of
any Person, the capitalized amount thereof that would appear on a balance sheet of such Person
prepared as of such date in accordance with GAAP, and (b) in respect of any Synthetic Lease
Obligation, the capitalized amount of the remaining lease payments under the relevant lease that
would appear on a balance sheet of such Person prepared as of such date in accordance with GAAP if
such lease were accounted for as a capital lease.

     “Base Rate” means, on any date and with respect to all Base Rate Loans, a fluctuating
rate of interest per annum equal to the higher of (a) the rate of interest most recently announced
by The Bank of Nova Scotia at its New York office as its base rate for dollar advances made in the
United States or (b) the Federal Funds Rate most recently determined by the Administrative Agent
plus 1/2% (0.5%) per annum. The Base Rate is not necessarily intended to be the lowest rate
of interest determined by The Bank of Nova Scotia or any Lender in connection with extensions of
credit. Changes in the rate of interest on that portion of any Loans maintained as Base Rate Loans
will take effect simultaneously with each change in the Base Rate. The Administrative Agent will
give notice to the Borrower of changes in the Base Rate promptly upon receipt of notice of any such
change from The Bank of Nova Scotia.

     “Base Rate Loan” means a Loan that bears interest based on the Base Rate.

     “Base Rate Spread” means, with respect to any Base Rate Loan for any time prior to the
Maturity Date, the percentage per annum set forth below under the caption “Base Rate Spread”,
determined by reference to the percentage of the Borrowing Base that the sum of all Loans
outstanding plus all L/C Obligations represents at that time.

     SECTION 2.1 Loans. Subject to the terms and conditions set forth herein, each Lender
severally agrees to make loans (each such loan, a “Loan”) to the Borrower from time to time
on any Business Day during the period from the Closing Date to the Maturity Date, in an aggregate
amount not to exceed at any time outstanding the lesser of (x) such Lender’s Percentage Share of
the aggregate amount of the Loans requested by the Borrower on such day and (y) the amount of such
Lender’s Commitment; provided, however, that after giving effect to any borrowing,
(i) the aggregate Outstanding Amount of all Loans and L/C Obligations shall not exceed the lesser
of (A) the Aggregate Commitments on such date and (B) the Borrowing Base then in effect, and (ii)
the aggregate Outstanding Amount of the Loans of any Lender, plus such Lender’s Percentage
Share of the Outstanding Amount of all L/C Obligations shall not exceed such Lender’s Commitment or
such Lender’s Percentage Share of the Borrowing Base. Within the limits of each Lender’s
Commitment, and subject to the other terms and conditions hereof, the Borrower may borrow under
this Section 2.1, prepay under Section 2.4 and reborrow under this Section
2.1.

     SECTION 2.2 Borrowings, Conversions and Continuations of Loans.

     (a) Each Borrowing, each conversion of Loans from one Type to the other, and each
continuation of Loans as the same Type shall be made upon the Borrower’s irrevocable prior written
notice to the Administrative Agent in the form of a Notice of Advance. Each such notice must be
received by the Administrative Agent not later than 11:00 a.m., central time, (i) three Business
Days prior to the requested date of any Borrowing of, conversion to
or continuation of LIBO Rate Loans or of any conversion of LIBO Rate Loans to Base Rate Loans,
and (ii) on the requested date of any Borrowing of Base Rate Loans. Each Notice of Advance shall
be appropriately completed and signed by a Responsible Officer of the Borrower. Each Borrowing of,
conversion to or continuation of LIBO Rate Loans shall be in a principal amount of $1,000,000 or a
whole multiple of $1,000,000 in excess thereof. Each Borrowing of or conversion to Base Rate Loans
shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each
Notice of Advance shall specify (i) whether the Borrower is requesting a Borrowing, a conversion of
Loans from one Type to the other, or a continuation of Loans as the same Type, (ii) the requested
date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business
Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of
Loans to be borrowed or to which existing Loans are to be converted or continued, and (v) if
applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to
specify a Type of Loan in a Notice of Advance or if the Borrower fails to give a timely notice
requesting a conversion or continuation, then the applicable Loans shall be made or continued as,
or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be
effective as of the last day of the Interest

 - 20 -

 

Period then in effect with respect to the applicable
LIBO Rate Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of LIBO
Rate Loans in any such Notice of Advance, but fails to specify an Interest Period, it will be
deemed to have specified an Interest Period of one month.

     (b) Following receipt of a Notice of Advance, the Administrative Agent shall
promptly notify each Lender of its Percentage Share of the applicable Loans, and if no timely
notice of a conversion or continuation is provided by the Borrower, the Administrative Agent shall
notify each Lender of the details of any automatic conversion to or continuation as Base Rate Loans
described in the preceding subsection. Each Lender shall make the amount of its Loan available to
the Administrative Agent in immediately available funds at the Administrative Agent’s Office not
later than 1:00 p.m. central time, on the Business Day specified in the applicable Notice of
Advance. Upon satisfaction of the applicable conditions set forth in Section 4.2 (and, if
such Borrowing is the initial Credit Extension, Section 4.1), the Administrative Agent
shall make all funds so received available to the Borrower in like funds as received by the
Administrative Agent either by (i) crediting the account of the Borrower on the books of Scotia
Capital with the amount of such funds or (ii) wire transfer of such funds, in each case in
accordance with instructions provided to the Administrative Agent by the Borrower;
provided, however, that if, on the date of the Borrowing there are L/C Borrowings
outstanding, then the proceeds of such Borrowing shall be applied, first, to the payment in
full of any such L/C Borrowings, and second, to the Borrower as provided above. Unless the
Administrative Agent shall have received prompt notice from a Lender that such Lender will not make
available to the Administrative Agent such Lender’s Loans, the Administrative Agent may in its
discretion assume that such Lender has made such Loans available to the Administrative Agent in
accordance with this section and the Administrative Agent may if it chooses, in reliance upon such
assumption, make such Loan available to the Borrower. If and to the extent such Lender shall not
so make its Loan available to the Administrative Agent, such Lender and the Borrower severally
agree to pay or repay to the Administrative Agent within two Business Days after demand the amount
of such Loan together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is paid or repaid to the Administrative Agent,
to be calculated as to such Lender at the lesser of: (x) the Federal Funds Rate and (y) the
Highest Lawful Rate, and to be calculated as to the Borrower at the interest rate applicable at the
time to the other Loans made on such date. If any Lender fails to make such payment to the
Administrative Agent within such two Business Day period, such Lender shall in addition to such
amount pay interest thereon, for each day from the date such Loan is made available to the Borrower
until the date such amount is paid or repaid to the Administrative Agent, at the interest rate
applicable at the time to the other Loans made on such date. The failure of any Lender to make any
Loan to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if
any, to make its Loan, but no Lender shall be responsible for the failure of any other Lender to
make any Loan to be made by such other Lender.

     (c) Except as otherwise provided herein, a LIBO Rate Loan may be continued or
converted only on the last day of the Interest Period for such LIBO Rate Loan. During the
existence of a Default, Event of Default or Borrowing Base Deficiency, no Loans may be requested
as, converted to or continued as LIBO Rate Loans.

 - 21 -

 

     (d) The Administrative Agent shall promptly notify the Borrower and the Lenders of
the interest rate applicable to any LIBO Rate Loan upon determination of such interest rate. The
determination of the LIBO Rate by the Administrative Agent shall be conclusive in the absence of
manifest error.

     (e) After giving effect to all Borrowings, all conversions of Loans from one Type
to the other, and all continuations of Loans as the same Type, there shall not be more than five
(5) LIBO Interest Periods in effect with respect to Loans.

guidelines (whether or not having the
force of law) or it subjects the Issuing Bank to any cost not anticipated by
the Issuing Bank on the date hereof;

     (G) the form and terms of such Letter of Credit are not acceptable to
the Administrative Agent and Issuing Bank in their sole and absolute discretion; and

     (H) any other condition in this Agreement to the issuance (renewal or
extension) of such Letter of Credit has not been satisfied.

     (iii) The Issuing Bank shall be under no obligation to amend any Letter of
Credit if (A) the Issuing Bank would have no obligation at such time to issue such Letter of
Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of
Credit does not accept the proposed amendment to such Letter of Credit.

     (i) Each Letter of Credit shall be issued or amended, as the case may be,

detail satisfactory to the Issuing Bank (A) the Letter of Credit to be amended; (B) the
proposed date of amendment thereof (which shall be a

 - 23 -

 

Business Day); (C) the nature of the
proposed amendment; and (D) such other matters as the Issuing Bank may require.

     (ii) Promptly after receipt of any Letter of Credit Application, the Issuing
Bank will confirm with the Administrative Agent (by telephone or in writing) that the
Administrative Agent has received a copy of such Letter of Credit Application from the
Borrower and, if not, the Issuing Bank will provide the Administrative Agent with a copy
thereof. Upon receipt by the Issuing Bank of confirmation from the Administrative Agent
that the requested issuance or amendment is permitted in accordance with the terms hereof,
then, subject to the terms and conditions hereof, the Issuing Bank shall, on the requested
date, issue a Letter of Credit for the account of the Borrower or enter into the applicable
amendment, as the case may be, in each case in accordance with the Issuing Bank’s usual and
customary business practices. Immediately upon the issuance of each Letter of Credit, each
Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to and hereby
does, purchase from the Issuing Bank a participation in such Letter of Credit in an amount
equal to the product of such Lender’s Percentage Share times the amount of such Letter of
Credit.

     2.3.3 Drawings and Reimbursements; Funding of Participations.

     (i) Upon any drawing under any Letter of Credit, the Issuing Bank shall
notify the Borrower and the Administrative Agent thereof. Not later than 11:00 a.m.,
central time, on the date of any payment
by the Issuing Bank under a Letter of Credit (each such date, an “Honor Date”),
the Borrower shall reimburse the Issuing Bank through the Administrative Agent in an amount
equal to the amount of such drawing. If the Borrower fails to so reimburse the Issuing Bank
by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date,
the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and such
Lender’s Percentage Share thereof. In such event, the Borrower shall be deemed to have
requested a Borrowing of Base Rate Loans to be disbursed on the Honor Date in an amount
equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in
Section 2.2 for the principal amount of Base Rate Loans, but subject to the amount
of the unutilized portion of the lesser of (x) the Aggregate Commitments and (y) the
Borrowing Base then in effect and the conditions set forth in Section 4.2 (other
than the delivery of a Notice of Advance). Any notice given by the Issuing Bank or the
Administrative Agent pursuant to this Section 2.3.3(i) may be given by telephone if
immediately confirmed in writing; provided that the lack of such an immediate
confirmation shall not affect the conclusiveness or binding effect of such notice.

     (ii) Each Lender (including the Lender acting as Issuing Bank) shall upon any
notice from the Administrative Agent pursuant to Section 2.3.3(i) make funds
available to the Administrative Agent for the account of the Issuing Bank at the
Administrative Agent’s Office in an amount equal to such Lender’s Percentage Share of the
Unreimbursed Amount not later than 1:00 p.m., central time, on the Business Day specified in
such notice by the Administrative Agent, whereupon, subject to the provisions of Section
2.3.3(iii), each Lender that so makes funds available shall be

 - 24 -

 

deemed to have made a
Base Rate Loan to the Borrower in such amount. The Administrative Agent shall remit the
funds so received to the Issuing Bank.

     (iii) With respect to any Unreimbursed Amount that is not fully refinanced by
a Borrowing of Base Rate Loans because the conditions set forth in Section 4.2
cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred
from the Issuing Bank an L/C Borrowing in the amount of the Unreimbursed Amount that is not
so refinanced, which L/C Borrowing shall be due and payable on demand (together with
interest) and shall bear interest at the lesser of: (x) the Default Rate and (y) the
Highest Lawful Rate. In such event, each Lender’s payment to the Administrative Agent for
the account of the Issuing Bank pursuant to Section 2.3.3(ii) shall be deemed
payment in respect of its participation in such L/C Borrowing and shall constitute an L/C
Advance from such Lender in satisfaction of its participation obligation under this
Section 2.3.3.

     (iv) Until each Lender funds its Loan or L/C Advance pursuant to this
Section 2.3.3 to reimburse the Issuing Bank for any amount drawn under any Letter of
Credit, interest in respect of such Lender’s Percentage Share of such amount shall be solely
for the account of the Issuing Bank.

     (v) Each Lender’s obligation to make Loans or L/C Advances to reimburse the
Issuing Bank for amounts drawn under Letters of Credit, as contemplated by this Section
2.3.3, shall be absolute and unconditional and shall not be affected by any
circumstance, including (A) any set-off, counterclaim, recoupment, defense or other right
which such Lender may have against the Issuing Bank, the Borrower or any other Person for
any reason whatsoever; (B) the occurrence or continuance of a Default or Event of Default,
or (C) any other occurrence, event or condition, whether or not similar to any of the
foregoing. Any such reimbursement shall not relieve or otherwise impair the obligation of
the Borrower to reimburse the Issuing Bank for the amount of any payment made by the Issuing
Bank under any Letter of Credit, together with interest as provided herein.

     (vi) If any Lender fails to make available to the Administrative Agent for
the account of the Issuing Bank any amount required to be paid by such Lender pursuant to
the foregoing provisions of this Section 2.3.3 by the time specified in Section
2.3.3(ii), the Issuing Bank shall be entitled to recover from such Lender (acting
through the Administrative Agent), on demand, such amount with interest thereon for the
period from the date such payment is required to the date on which such payment is
immediately available to the Issuing Bank at a rate per annum equal to (1) for the first two
Business Days immediately following the date such payment is required, the lesser of: (x)
the Federal Funds Rate and (y) the Highest Lawful Rate from time to time in effect, and (2)
for each day thereafter, at the lesser of: (x) the Base Rate and (y) the Highest Lawful
Rate from time to time in effect. A certificate of the Issuing Bank submitted to
any Lender (through the Administrative Agent) with respect to any amounts owing under
this clause (vi) shall be conclusive absent manifest error.

 - 25 -

 

     2.3.4 Repayment of Participations.

     (i) At any time after the Issuing Bank has made a payment under any Letter of
Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment
in accordance with Section 2.3.3, if the Administrative Agent receives for the
account of the Issuing Bank any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the
Administrative Agent), or any payment of interest thereon, the Administrative Agent will
distribute to such Lender its Percentage Share thereof in the same funds as those received
by the Administrative Agent.

     (ii) If any payment received by the Administrative Agent for the account of
the Issuing Bank pursuant to Section 2.3.3 is required to be returned, each Lender
shall pay to the Administrative Agent for the account of the Issuing Bank its Percentage
Share thereof on demand of the Administrative Agent, plus interest thereon from the
date of such demand to the date such amount is returned by such Lender, at a rate per annum
equal to (1) with respect to the first two Business Days immediately following such demand,
the lesser of: (x) the Federal Funds Rate and (y) the Highest Lawful Rate from time to time
in effect, and (2) with respect to each day thereafter, the lesser of: (x) the Base Rate
and (y) the Highest Lawful Rate from time to time in effect.

     2.3.5 Obligations Absolute. The obligation of the Borrower to reimburse the
Issuing Bank for each drawing under each Letter of Credit, and to repay each L/C Borrowing and each
drawing under a Letter of Credit that is refinanced by a Borrowing of Loans, shall be absolute,
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including the following:

     (i) any lack of validity or enforceability of such Letter of Credit, this
Agreement, or any other agreement or instrument relating thereto;

     (ii) the existence of any claim, counterclaim, set-off, defense or other
right that any Loan Party may have at any time against any beneficiary or any transferee of
such Letter of Credit (or any Person for whom any such beneficiary or any such transferee
may be acting), the Issuing Bank or any other Person, whether in connection with this
Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement
or instrument relating thereto, or any unrelated transaction;

     (iii) any draft, demand, certificate or other document presented under such
Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or
any statement therein being untrue or inaccurate in any respect; or any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit;

     (iv) any payment by the Issuing Bank under such Letter of Credit against
presentation of a draft or certificate that does not strictly comply with the terms of such
Letter of Credit; or any payment made by the Issuing Bank under such Letter of Credit to any
Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for

 - 26 -

 

the
benefit of creditors, liquidator, receiver or other representative of or successor to any
beneficiary or any transferee of such Letter of Credit, including any arising in connection
with any proceeding under any Debtor Relief Law; or

     (v) any other circumstance or happening whatsoever, whether or not similar to
any of the foregoing, including any other circumstance that might otherwise constitute a
defense available to, or a discharge of, the Borrower or any other Loan Party.

     The Borrower shall promptly examine a copy of each Letter of Credit and each amendment
thereto that is delivered to it and, in the event of any claim of noncompliance with the
Borrower’s instructions or other irregularity, the Borrower will promptly notify the Issuing
Bank thereof in writing. The Borrower shall be conclusively deemed to have waived any such
claim against the Issuing Bank and its correspondents unless such notice is given as
aforesaid.

     2.3.6 Role of Issuing Bank; Indemnity. Each Lender and the Borrower agree that,
in paying any drawing under a Letter of Credit, the Issuing Bank shall not have any responsibility
to obtain any document (other than any sight draft, certificates and documents expressly required
by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such
document or the authority of the Person executing or delivering any such document. No
Agent-Related Person nor any of the respective correspondents, participants or assignees of the
Issuing Bank shall be liable to any Lender for (i) any action taken or omitted in connection
herewith at the request or with the approval of the Lenders or the Majority Lenders, as applicable;
(ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii)
the due execution, effectiveness, validity or enforceability of any document or instrument related
to any Letter of Credit or Letter of Credit Application. The Borrower hereby assumes all risks of
the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of
Credit. No Agent-Related Person, nor any of the respective correspondents, participants or
assignees of the Issuing Bank, shall be liable or responsible for any of the matters described in
clauses (i) through (v) of Section 2.3.5. The Borrower agrees to hold Issuing Bank and
each Lender harmless and indemnified against any liability or claim in connection with or arising
out of the subject matter of this section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH
LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT
OR OMISSION OR STRICT LIABILITY OF ANY KIND BY ISSUING BANK OR ANY LENDER, provided only that the
Issuing Bank or such Lender shall not be entitled to indemnification for that portion, if any, of
any liability or claim which is proximately caused by its own individual gross negligence or
willful misconduct as determined in a final judgment. In furtherance and not in limitation of the
foregoing, the Issuing Bank may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or information to the contrary,
and the Issuing Bank shall not be responsible for the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or
ineffective for any reason. If any Letter of Credit provides that it is transferable, the Issuing
Bank shall have no duty to determine the proper identity of anyone appearing as transferee of such
Letter of Credit, nor shall the Issuing Bank be charged with responsibility of any nature or
character for the validity or correctness of any transfer or successive transfers, and

 - 27 -

 

payment by
the Issuing Bank to any purported transferee or transferees as determined by the Issuing Bank is
hereby authorized and approved, and the Borrower further agrees to hold the Issuing Bank and each
Lender harmless and indemnified against any liability or claim in connection with or arising out of
the foregoing, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY
OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OR STRICT LIABILITY
OF ANY KIND BY THE ISSUING BANK OR ANY LENDER, provided only that the Issuing Bank or such Lender
shall not be entitled to indemnification for that portion, if any, of any liability or claim which
is caused by its own individual gross negligence or willful misconduct as determined in a final
judgment. All of Borrower’s Obligations under this Section 2.3.6 shall survive termination
of the Commitments or of this Agreement and repayment in full of the Obligations.

     2.3.7 Applicability of ISP98 and UCP. Unless otherwise expressly agreed by the
Issuing Bank and the Borrower when a Letter of Credit is issued, (i) the rules of the
“International Standby Practices 1998” published by the Institute of International Banking Law &
Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to
each standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for
Documentary Credits, as most recently published by the International Chamber of Commerce (the
“ICC”) at the time of issuance (including the ICC decision published by the Commission on
Banking Technique and Practice on April 6, 1998 regarding the European single currency (euro))
shall apply to each commercial Letter of Credit.

     2.3.8 Letter of Credit Fees.
The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance
with its Percentage Share a Letter of Credit fee for each Letter of Credit equal to the LIBOR
Spread then in effect with respect to Loans after giving effect to the L/C Obligations incurred
with respect to such Letter of Credit times the actual daily maximum amount available to be
drawn under such Letter of Credit. Such fee for each Letter of Credit shall be due and payable on
the last Business Day of each March, June, September and December, commencing with the first such
date to occur after the issuance of such Letter of Credit, and on the Letter of Credit Availability
Expiration Date. If there is any change in the LIBOR Spread during any quarter, the actual daily
amount of each Letter of Credit shall be computed and multiplied by the LIBOR Spread with respect
to Letters of Credit separately for each period during such quarter that such LIBOR Spread was in
effect.

     2.3.9 Letter of Credit Fronting Fee and Documentary and Processing Charges Payable to
Issuing Bank. The Borrower shall pay directly to the Issuing Bank for its own account a
fronting fee as set forth in the Fee Letter, due and payable quarterly in arrears on the last
Business Day of each March, June, September and December, commencing with the first such date to
occur after the issuance of such Letter of Credit, and on the Letter of Credit Availability
Expiration Date; provided that all such fees shall be payable on the date on which the
Commitments terminate and any such fees accruing after the date on which the Commitments terminate
shall be payable on demand. In addition, the Borrower shall pay directly to the Issuing Bank for
its own account the customary issuance, presentation, amendment and other processing fees, and
other standard costs and charges, of the Issuing Bank relating to letters of credit as from time to
time in effect. Such fees and charges are due and payable on demand and are nonrefundable. All
participation fees and fronting fees shall be computed on the basis of a year

 - 28 -

 

of 360 days and shall
be payable for the actual number of days elapsed (including the first day but excluding the last
day).

     2.3.10 Conflict with Letter of Credit Application. In the event of any conflict
between the terms hereof and the terms of any Letter of Credit Application, the terms hereof shall
control.

     2.3.11 L/C Collateral.

     (a) L/C Obligations in Excess of Borrowing Base or upon Termination of
Commitments. (i) If, after the making of all mandatory prepayments required under Section
2.4.2, the aggregate amount of all Loans outstanding plus all L/C Obligations
outstanding excluding L/C Obligations secured by cash collateral pursuant to this Section
2.3.11 will exceed the Borrowing Base, then the Borrower will immediately pay to the Issuing
Bank an amount in cash equal to such excess, or (ii) should any L/C Obligations remain outstanding
on the Maturity Date, then the Borrower will immediately pay the Issuing Bank an amount in cash
equal to the aggregate amount of such Issuing Bank’s L/C Obligations. The Issuing Bank will hold
such amount as security for the remaining L/C Obligations (“L/C Collateral”) until such L/C
Obligations become Matured L/C Obligations, at which time such L/C Collateral may be applied to
such Matured L/C Obligations. Neither this subsection nor the following subsection shall, however,
limit or impair any rights which the Issuing Bank may have under any other document or agreement
relating to any Letter of Credit or L/C Obligation, including any Letter of Credit Application, or
any rights which the Issuing Bank or Lenders may have to otherwise apply any payments by the
Borrower and L/C Collateral under Section 2.3.11.

     (b) Acceleration of L/C Obligations. If the Obligations or any part thereof
become immediately due and payable pursuant to Section 8.2 then, unless the Majority
Lenders otherwise specifically elect to the contrary (which election may thereafter be retracted by
the Majority Lenders at any time), all L/C Obligations shall become immediately due and payable
without regard to whether or not actual drawings or payments on the Letters of Credit have
occurred, and the Borrower shall be obligated to pay to the Issuing Bank immediately an amount
equal to the aggregate L/C Obligations which are then outstanding. All amounts so paid shall first
be applied to Matured L/C Obligations and then held by the Issuing Bank as L/C Collateral until
such L/C Obligations become Matured L/C Obligations, at which time such L/C Collateral shall be
applied to such Matured L/C Obligations.

     (c) Investment of L/C Collateral. Pending application thereof, all L/C
Collateral shall be invested by the Issuing Bank in such blocked account as the Issuing Bank may
choose in its sole discretion. All interest on such investments shall be reinvested or applied to
Matured L/C Obligations. When all Obligations have been satisfied in full, including all L/C
Obligations, all Letters of Credit have expired or been terminated, and all of the Borrower’s
reimbursement obligations in connection therewith have been satisfied in full, the Issuing Bank
shall release any remaining L/C Collateral. The Borrower hereby assigns and grants to the Issuing
Bank a continuing security interest in all L/C Collateral paid by it to the Issuing Bank, all
investments purchased with such L/C Collateral, and all proceeds thereof to secure its Matured L/C
Obligations and its Obligations under this Agreement, the Notes, and the other Loan Documents, and
the Borrower agrees that such L/C Collateral and investments shall be subject to all of the terms
and conditions of the Borrower’s Security Agreement. The Borrower further agrees that

 - 29 -

 

the Issuing
Bank shall have all of the rights and remedies of a secured party under the Uniform Commercial Code
as adopted in the State of Texas with respect to such security interest and that an Event of
Default under this Agreement shall constitute a default for purposes of such security interest and
the exercise of such rights and remedies.

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

     SECTION 2.4 Prepayments.

     2.4.1 Voluntary Prepayments. The Borrower may, upon notice to the Administrative
Agent, at any time or from time to time voluntarily prepay Loans in whole or in part without
premium or penalty; provided that (i) such notice must be received by the Administrative
Agent not later than 11:00 a.m., central time, (A) three Business Days prior to any date of
prepayment of LIBO Rate Loans, and (B) on the date of prepayment of Base Rate Loans; (ii) any
prepayment of LIBO Rate Loans shall be in a principal amount of $1,000,000 or a whole multiple of
$1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal
amount of $500,000 or a whole multiple of $100,000 in excess thereof. Each such notice shall
specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid. The
Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of
such Lender’s Percentage Share of such prepayment. If such notice is given by the Borrower, the
Borrower shall make such prepayment and the payment amount specified in such notice shall be due
and payable on the date specified therein. Any prepayment of a LIBO Rate Loan shall be accompanied
by all accrued interest thereon, together with any additional amounts required pursuant to
Section 3.5. Each such prepayment shall be applied to the Loans of the Lenders in
accordance with their respective Percentage Shares.

     2.4.2 Mandatory Prepayments. The Borrower shall make the following prepayments
of the Loans:

     (i) Outstandings Exceed Commitments. Subject to Section 2.4.2(ii), if for
any reason the Outstanding Amount of all Loans and L/C Obligations at any time exceeds the
Aggregate Commitments then in effect, the Borrower shall first immediately prepay Loans and
following prepayment of the Loans, then Cash Collateralize the L/C Obligations in an
aggregate amount equal to such excess.

     (ii) Borrowing Base Deficiency.

     (A) If at any time the aggregate unpaid principal balance of the
Loans plus the aggregate amount of L/C Obligations exceeds the Borrowing
Base (a “Borrowing Base Deficiency”), the Borrower shall, within thirty (30)
days after the Administrative Agent sends written notice of such fact to the
Borrower, (1) prepay the principal of the Loans (and, upon
prepayment of all Loans, shall, to the extent required, provide L/C Collateral
as set forth in Section 2.3.11) in an aggregate amount at least equal to
such Borrowing Base Deficiency (in this section, a “Mandatory Prepayment
Amount”), or (2) give notice to the

 - 30 -

 

Administrative Agent electing to prepay such
Mandatory Prepayment Amount in six (6) (or fewer) monthly installments. Each such
installment shall equal or exceed one-sixth of such Borrowing Base Deficiency; the
first such installment shall be paid within thirty (30) days of the giving of such
notice of the Borrowing Base Deficiency by the Administrative Agent to the Borrower
and the five (or fewer) subsequent installments shall be due and payable at one
month intervals thereafter until such Borrowing Base Deficiency has been eliminated.

     (B) If (1) at any time during the existence or continuation of a
Borrowing Base Deficiency, the Borrower or any Guarantor makes a Disposition of
assets (other than those described in clauses (a) through (d) of Section 7.5
hereof), or (2) a Disposition of assets included in the Borrowing Base results in a
reduction of the Borrowing Base in accordance with Section 7.5(e) such that
a Borrowing Base Deficiency occurs, then, in either case, the Borrower shall, or
shall cause such Guarantor to, use the Net Sale Proceeds from such Disposition
(whether or not such assets are included in the Borrowing Base) to prepay the Loans
and, upon prepayment of all Loans, shall provide L/C Collateral as set forth in
Section 2.3.11, within one (1) Business Day of such Disposition in an amount
equal to 100% of the Borrowing Base Deficiency then existing or occurring as a
result of such disposition. Application of such Net Sales Proceeds shall be applied
to the principal amount of the Loans until the Loans are paid in full and then shall
be held as L/C Collateral in an amount equal to the aggregate amount of L/C
Obligations pursuant to Section 2.3.11.

     SECTION 2.5 Reduction or Termination of Commitments and Maximum Loan Amount. The
Borrower may, upon notice to the Administrative Agent, terminate the Aggregate Commitments and
Maximum Loan Amount, or permanently reduce the Aggregate Commitments and Maximum Loan Amount to an
amount not less than the then Outstanding Amount of all Loans and L/C Obligations; provided
that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m.,
central time three (3) Business Days prior to the date of termination or reduction, and (ii) any
such partial reduction shall be in an aggregate amount of $5,000,000 or any whole multiple of
$1,000,000 in excess thereof. The Administrative Agent shall promptly notify the Lenders of any
such notice of reduction or termination of the Aggregate Commitments and Maximum Loan Amount. Once
reduced in accordance with this Section, the Commitments may not be increased. Any reduction of
the Aggregate Commitments shall be applied to the Commitment of each Lender according to its
Percentage Share. All commitment fees accrued until the effective date of any termination of the
Aggregate Commitments shall be paid on the effective date of such termination.

     SECTION 2.6 Repayment of Loans. The Borrower shall repay to the Lenders on the Maturity
Date the aggregate principal amount of Loans outstanding on such date, any accrued and unpaid
interest thereon, any fees, expenses and other Obligations remaining unpaid.

     SECTION 2.7 Initial Borrowing Base. On any date during the period from the Closing Date
to the first Evaluation Date, the Borrowing Base shall be an amount equal to $100,000,000.

 - 31 -

 

     SECTION 2.8 Subsequent Determinations of Borrowing Base.

     (a) By each Evaluation Date, the Borrower shall furnish to the Administrative Agent
and each Lender all information, reports and data which the Administrative Agent has then
reasonably requested concerning the Borrower’s and the Guarantors’ businesses and properties
(including Borrower’s and the Guarantors’ Oil and Gas
Properties and interests and the reserves and production relating thereto), together with the
Engineering Report described in Section 6.2(g), if an Engineering Report is then due.
Within thirty (30) days after receiving such information, reports and data, or as promptly
thereafter as practicable, the Administrative Agent shall recommend a redetermined Borrowing Base
to the Lenders. Such recommended Borrowing Base shall become effective upon the receipt by the
Administrative Agent of the approval of the Majority Lenders. The failure of a Lender to respond
or object in writing to the recommended Borrowing Base within fifteen (15) days after notice
thereof is given to such Lender by the Administrative Agent shall be deemed an acceptance and
approval of such recommended Borrowing Base by such Lender. If such recommended Borrowing Base is
not approved by Majority Lenders within fifteen (15) days after the Administrative Agent submits
the recommended Borrowing Base to the Lenders, then each Lender shall submit in writing to the
Administrative Agent, on or within fifteen (15) days after the Administrative Agent notifies the
Lenders that the Lenders have not approved any such recommended Borrowing Base, such Lender’s
determination of the redetermined Borrowing Base; in such case, the redetermined Borrowing Base
shall be the highest amount approved by the Majority Lenders. NOTWITHSTANDING ANYTHING HEREIN TO
THE CONTRARY, WITHOUT THE PRIOR WRITTEN APPROVAL OF ALL OF THE LENDERS, SUCH APPROVAL TO BE IN EACH
LENDER’S SOLE DISCRETION, THE REDETERMINED BORROWING BASE SHALL NOT BE INCREASED ABOVE THE AMOUNT
OF THE BORROWING BASE IN EFFECT IMMEDIATELY PRIOR TO SUCH REDETERMINATION. The Administrative
Agent shall by notice to the Borrower and the Lenders designate the amount of the Borrowing Base
(determined by the Majority Lenders or all of the Lenders, as applicable, in accordance with the
foregoing procedures) available to the Borrower hereunder, which designation shall take effect
immediately on the date such notice is sent (a “Determination Date”) and shall remain in
effect until but not including the next date as of which the Borrowing Base is redetermined. If
the Borrower does not furnish all such information, reports and data by the date specified in the
first sentence of this section, the Administrative Agent may nonetheless designate the Borrowing
Base at any amount which the Lenders determine, and may redesignate the Borrowing Base from time to
time thereafter at any amount which all Lenders redetermine, until each Lender receives all such
information, reports and data, whereupon Lenders shall designate a new Borrowing Base as described
above. The Lenders shall determine the amount of the Borrowing Base based upon the loan collateral
value which they, in their sole discretion and in accordance with their respective normal practices
and standards for oil and gas loans as such practices and standards exist at the particular time,
assign to the various Oil and Gas Properties of the Borrower or the Guarantors at the time in
question and based upon such other factors (including without limitation the assets, liabilities,
fixed charges, cash flow, business, properties, prospects, management and ownership of any of the
Borrower or the Guarantors or any Subsidiary of any of the Borrower or the Guarantors) as they, in
their sole discretion and in accordance with their respective normal practices and standards for
oil and gas loans as such practices and standards exist at the particular time, deem significant.
It is expressly understood that Lenders and the Administrative Agent have no obligation to agree
upon or designate the Borrowing Base at any

 - 32 -

 

particular amount, whether in relation to the Maximum
Loan Amount or otherwise, and that the Lenders’ commitments to advance funds hereunder is
determined by reference to the Borrowing Base from time to time in effect, which Borrowing Base
shall be used for calculating commitment fees under Section 2.10(a). Additional
redeterminations at the request of the Lenders, the Administrative Agent or the Borrower shall be
subject to a $5,000 engineering fee payable by Borrower to the Administrative Agent for its own
account.

     (b) The Borrower may include additional Oil and Gas Properties of the Borrower or
the Guarantors acquired from time to time as Collateral for the Obligations, which may then be
included in the calculation of the Borrowing Base, by the Borrower (A) giving written notice to the
Administrative Agent of such properties to be included, (B) subjecting such properties to Liens
securing the Obligations (pursuant to Security Documents satisfactory to the Administrative Agent)
if necessary to comply with the provisions of Section 6.15, (C) including such properties
in an Engineering Report submitted to the Administrative Agent and (D) delivering to the
Administrative Agent title opinions covering at least 80% of the additional value of such
properties addressed to the Administrative Agent for the benefit of the Lenders covering all of
such properties and other legal opinions from counsel acceptable to the Administrative Agent, in
its sole discretion, in form, scope and substance acceptable to the Administrative Agent opining
favorably as to, among such other matters as may be required by the Administrative Agent, (1) the
Borrower’s or the appropriate Guarantor’s ownership of such properties and (2) matters of the type
covered by the opinions delivered pursuant to Section 4.1(a)(vi).

     (c) In addition to any scheduled determination or discretionary determination of the
Borrowing Base, the Borrowing Base shall be automatically reduced from time to time as set forth in
Section 7.5(f).

     SECTION 2.9 Interest.

     (a) Subject to the provisions of subsection (b) below, (i) each LIBO Rate
Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a
rate per annum equal to the lesser of (i) the Adjusted LIBO Rate for such Interest Period
plus the LIBOR Spread and (ii) the Highest Lawful Rate; and (ii) each Base Rate Loan shall
bear interest on the outstanding principal amount thereof from the applicable borrowing date at a
rate per annum equal to the lesser of (i) the Base Rate plus the Base Rate Spread and (ii)
the Highest Lawful Rate.

     (b) While any Event of Default or Borrowing Base Deficiency exists or after
acceleration, the Borrower shall pay interest on the principal amount of all outstanding
Obligations at a fluctuating interest rate per annum at all times equal to the lesser of (i) the
Default Rate and (ii) the Highest Lawful Rate to the fullest extent permitted by applicable Law.
Accrued and unpaid interest on past due amounts (including interest accrued on past due interest)
shall be due and payable upon demand.

     (c) Interest accrued on each Loan shall be due and payable in arrears on each
Interest Payment Date applicable thereto and at such other times as may be specified herein.
Interest hereunder shall be due and payable in accordance with the terms hereof before and after

 - 33 -

 

judgment, and before and after
the commencement of any proceeding under any Debtor Relief Law.

     SECTION 2.10 Fees. In addition to certain fees described in Sections 2.3.8 and
2.3.9:

     (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for
the account of each Lender in accordance with its Percentage Share, a commitment fee equal to the
Commitment Fee Rate times the actual daily amount by which the Aggregate Commitments exceed
the sum of (i) the Outstanding Amount of Loans and (ii) the Outstanding Amount of L/C Obligations.
The commitment fee shall accrue at all times from the date of this Agreement until the Maturity
Date and shall be due and payable quarterly in arrears on the last Business Day of each March,
June, September and December, commencing with the first such date to occur after the Closing Date,
and on the Maturity Date. The commitment fee shall be calculated quarterly in arrears, and if
there is any change in the Commitment Fee Rate with respect to Commitment fees during any quarter,
the actual daily amount shall be computed and multiplied by the Commitment Fee Rate with respect to
Commitment fees separately for each period during such quarter that such Commitment Fee Rate was in
effect. The commitment fee shall accrue at all times, including at any time during which one or
more of the conditions in Article IV is not met.

     (b) Arrangement and Agency Fees. The Borrower shall pay an arrangement fee
to the Arranger for the Arranger’s own account, and shall pay an agency fee to the Administrative
Agent for the Administrative Agent’s own account, in the amounts and at the times specified in the
letter agreement, dated October 25, 2004 (the “Agent and Arranger Fee Letter”), among the
Borrower, the Arranger and the Administrative Agent. Such fees shall be fully earned when paid and
shall be nonrefundable for any reason whatsoever.

     SECTION 2.11 Computation of Interest and Fees. Computation of interest on Base Rate
Loans and Commitment Fees shall be calculated on the basis of a year of 365 or 366 days, as the
case may be, and the actual number of days elapsed. Computation of all other types of interest and
all fees shall be calculated on the basis of a year of 360 days and the actual number of days
elapsed, which results in a higher yield to the payee thereof than a method based on a year of 365
or 366 days. Interest shall accrue on each Loan for the day on which the Loan is made, and shall
not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is
paid, provided that any Loan that is repaid on the same day on which it is made shall bear
interest for one day.

     SECTION 2.12 Notes and Other Evidence of Debt.

     (a) The obligation of the Borrower to repay to each Lender the aggregate amount of
all Loans made by such Lender (such Lender’s “Loan”), together with interest accruing in connection
therewith, shall be evidenced by a single promissory note (such Lender’s “Note”) made by the
Borrower in the amount of such Lender’s Percentage Share of the Maximum Loan Amount payable to the
order of such Lender substantially in the form of Exhibit B with appropriate insertions.
Each Lender may record the date, Type (if applicable), amount and maturity of the applicable Loans
and payments with respect thereto in one or more schedules to its Note or on one or more accounts
or records maintained by such Lender and by the Administrative Agent in the ordinary course of
business. The accounts or records maintained by

 - 34 -

 

the Administrative Agent and each Lender shall be
conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the
Borrower and the interest and payments thereon. Any failure so to record or any error in doing so
shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any
amount owing with respect to the Loans and L/C Obligations.

     (b) In addition to the accounts and records referred to in subsection (a),
each Lender and the Administrative Agent shall maintain in accordance with its usual practice
accounts or records evidencing the purchases and sales by such Lender of participations in Letters
of Credit. In the event of any conflict between the accounts and records maintained by the
Administrative Agent and the accounts and records of any Lender in respect of such matters, the
accounts and records of the Administrative Agent shall control.

     SECTION 2.13 Payments Generally.

     (a) All payments to be made by the Borrower or any other Loan Party shall be made
without condition or deduction for any counterclaim, defense, reservation, recoupment, setoff or
other matter. Except as otherwise expressly provided herein, all payments by the Borrower
hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to
which such payment is owed, at the Administrative Agent’s Office in Dollars and in immediately
available funds not later than 11:00 a.m., central time, on the date specified herein. The
Administrative Agent will promptly distribute to each Lender its Percentage Share (or other
applicable share as provided herein) of such payment in like funds as received by wire transfer to
such Lender’s Lending Office. All payments received by the Administrative Agent after 11:00 a.m.,
central time, shall be deemed received on the next succeeding Business Day and any applicable
interest or fee shall continue to accrue and any applicable indemnity or reimbursement obligation
shall be due and payable.

     (b) Subject to the definition of “Interest Period,” if any payment to be made by the
Borrower shall come due on a day other than a Business Day, payment shall be made on the next
following Business Day, and such extension of time shall be reflected in computing interest or
fees, as the case may be.

     (c) Unless the Borrower or any Lender has notified the Administrative Agent prior to
the date any payment is required to be made by it to the Administrative Agent hereunder, that the
Borrower or such Lender, as the case may be, will not make such payment, the Administrative Agent
may assume that the Borrower or such Lender, as the case may be, has timely made such payment and
may (but shall not be so required to), in reliance thereon, make available a corresponding amount
to the Person entitled thereto. If and to the extent that such payment was not in fact made to the
Administrative Agent in immediately available funds, then:

     (i) if the Borrower failed to make such payment, each Lender shall forthwith
on demand repay to the Administrative Agent the portion of such assumed payment that was
made available to such Lender in immediately available funds, together with interest thereon
(1) in respect of each of the first two Business Days from and including the date such
amount was made available by the Administrative Agent to such Lender to the date such amount
is repaid to the Administrative Agent in immediately available funds, at the

 - 35 -

 

lesser of: (x)
the Federal Funds Rate and (y) the Highest Lawful Rate from time to time in effect, and (2)
in respect of each day after the first two Business Days from and including the date such
amount was made available by the Administrative Agent to such Lender to the date such
amount is repaid to the Administrative Agent in immediately available funds, at a per annum
rate of interest equal to the lesser of (x) the Base Rate and (y) the Highest Lawful Rate,
in each case, from time to time in effect; and

     (ii) if any Lender failed to make such payment, such Lender shall forthwith
on demand pay to the Administrative Agent the amount thereof in immediately available funds,
together with interest thereon for the period from the date such amount was made available
by the Administrative Agent to the Borrower to the date such amount is recovered by the
Administrative Agent (the “Compensation Period”) at a rate per annum equal to the
lesser of (1) (x) for the first two Business Days of any Compensation Period, the Federal
Funds Rate from time to time in effect, and (y) for each other day of any Compensation
Period, the interest rate applicable to the applicable Borrowing and (2) the Highest Lawful
Rate. If such Lender pays such amount to the Administrative Agent, then such amount shall
constitute such Lender’s Loan included in the applicable Borrowing. If such Lender does not
pay such amount forthwith upon the Administrative Agent’s demand therefor, the
Administrative Agent may make a demand therefor upon the Borrower, and the Borrower shall
pay such amount to the Administrative Agent, together with interest thereon for the
Compensation Period at a rate per annum equal to the rate of interest applicable to the
applicable Borrowing. Nothing herein shall be deemed to relieve any Lender from its
obligation to fulfill its Commitment or to prejudice any rights that the Administrative
Agent or the Borrower may have against any Lender as a result of any default by such Lender
hereunder.

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

     (d) If any Lender makes available to the Administrative Agent funds for any Loan to
be made by such Lender as provided in the foregoing provisions of this Article II, and the
conditions to the applicable Credit Extension set forth in Article IV are not satisfied or
waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in
like funds as received from such Lender) to such Lender, without interest.

     (e) The obligations of the Lenders hereunder to make Loans and to fund
participations in Letters of Credit are several and not joint. The failure of any Lender to make
any Loan or to fund any such participation on any date required hereunder shall not relieve any
other Lender of its corresponding obligation to do so on such date, and no Lender shall be
responsible for the failure of any other Lender to so make its Loan or purchase its participation.

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

     SECTION 2.14 Sharing of Payments. If, other than as expressly provided elsewhere herein,
any Lender shall obtain on account of the Loans made by it, or the participations in L/C

 - 36 -

 

     Obligations held by it, any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) in excess of its ratable share (or other share contemplated
hereunder) thereof, such Lender shall immediately (a) notify the Administrative Agent of such fact,
and (b) purchase from the other Lenders such participations in the Loans made by them and/or such
subparticipations in the participations in L/C Obligations held by them, as the case may be, as
shall be necessary to cause such purchasing Lender to share the excess payment in respect of such
Loan or such participations, as the case may be, pro rata with each of them; provided,
however, that if all or any portion of such excess payment is thereafter recovered from the
purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall
repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to
such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying
Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a participation from
another Lender may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off, but subject to Section 10.9) with respect to such
participation as fully as if such Lender were the direct creditor of the Borrower in the amount of
such participation. The Administrative Agent will keep records (which shall be
conclusive and binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or repayments. Each
Lender that purchases a participation pursuant to this Section shall from and after such purchase
have the right to give all notices, requests, demands, directions and other communications under
this Agreement with respect to the portion of the Obligations purchased to the same extent as
though the purchasing Lender were the original owner of the Obligations purchased.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

     SECTION 3.1 Taxes.

     (a) Any and all payments by the Borrower to or for the account of the Administrative
Agent or any Lender under any Loan Document shall be made free and clear of and without deduction
for any and all present or future taxes, duties, levies, imposts, deductions, assessments, fees,
withholdings or similar charges, and all liabilities with respect thereto, excluding, in
the case of the Administrative Agent and each Lender, taxes imposed on or measured by its net
income, and franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or
any political subdivision thereof) under the Laws of which the Administrative Agent or such Lender,
as the case may be, is organized or maintains a lending office (all such non-excluded taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and
liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required
by any Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to
the Administrative Agent or any Lender, (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 and such Lender receives an amount equal to the sum
it would have received had no such deductions been made, (ii) the Borrower shall make such
deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable Laws, and (iv) within 30 days

 - 37 -

 

after the
date of such payment, the Borrower shall furnish to the Administrative Agent (which shall forward
the same to such Lender) the original or a certified copy of a receipt evidencing payment thereof.

     (b) In addition, the Borrower agrees to pay any and all present or future stamp,
court or documentary taxes and any other excise or property taxes or charges or similar levies
which arise from any payment made under any Loan Document or from the execution, delivery,
performance, enforcement or registration of, or otherwise with respect to, any Loan Document
(hereinafter referred to as “Other Taxes”).

     (c) If the Borrower shall be required to deduct or pay any Taxes or Other Taxes from
or in respect of any sum payable under any Loan Document to the Administrative Agent or any Lender,
the Borrower shall also pay to the Administrative Agent (for the account of such Lender) or to such
Lender, at the time interest is paid, such additional amount that such Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on
or measured by net income) such Lender would have received if such Taxes or Other Taxes had not
been imposed.

     (d) The Borrower agrees to indemnify the Administrative Agent and each Lender for
(i) the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or
asserted by any jurisdiction on amounts payable under this Section) paid by the Administrative
Agent and such Lender, (ii) amounts payable under Section 3.1(c) and (iii) any liability
(including penalties, interest and expenses) arising therefrom or with respect thereto, in each
case whether or not such Taxes or Other Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority. Payment under this subsection (d) shall be made within 30
days after the date the Lender or the Administrative Agent makes a demand therefor.

     SECTION 3.2 Illegality. If any Lender determines that any Law has made it unlawful, or
that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable
Lending Office to make, maintain or fund LIBO Rate Loans, or materially restricts the authority of
such Lender to purchase or sell, or to take deposits of, Dollars in the applicable offshore Dollar
market, or to determine or charge interest rates based upon the LIBO Rate, then, on notice thereof
by such Lender to the Borrower through the Administrative Agent, any obligation of such Lender to make
or continue LIBO Rate Loans or to convert Base Rate Loans to LIBO Rate Loans shall be suspended
until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving
rise to such determination no longer exist. Upon receipt of such notice, the Borrower shall, upon
demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable,
convert all LIBO Rate Loans of such Lender to Base Rate Loans, either on the last day of the
Interest Period thereof, if such Lender may lawfully continue to maintain such LIBO Rate Loans to
such day, or immediately, if such Lender may not lawfully continue to maintain such LIBO Rate
Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued and unpaid
interest on the amount so prepaid or converted. Each Lender agrees to designate a different
Lending Office if such designation will avoid the need for such notice and will not, in the good
faith judgment of such Lender, otherwise be disadvantageous to such Lender.

 - 38 -

 

     SECTION 3.3 Inability to Determine Rates. If the Administrative Agent determines in
connection with any request for a LIBO Rate Loan or a conversion to or continuation thereof that
(a) Dollar deposits are not being offered to banks in the applicable offshore Dollar market for the
applicable amount and Interest Period of such LIBO Rate Loan, (b) adequate and reasonable means do
not exist for determining the LIBO Rate for such LIBO Rate Loan, or (c) the Adjusted LIBO Rate for
such LIBO Rate Loan does not adequately and fairly reflect the cost to the Lenders of funding such
LIBO Rate Loan, the Administrative Agent will promptly notify the Borrower and all Lenders.
Thereafter, the obligation of the Lenders to make or maintain LIBO Rate Loans shall be suspended
until the Administrative Agent revokes such notice. Upon receipt of such notice, the Borrower may
revoke any pending request for a Borrowing, conversion or continuation of LIBO Rate Loans or,
failing that, will be deemed to have converted such request into a request for a Borrowing of Base
Rate Loans in the amount specified therein.

     SECTION 3.4 Increased Cost and Reduced Return; Capital Adequacy.

     (a) If any Lender determines that, as a result of the introduction of, or any change
in, or in the interpretation of any Law, or such Lender’s compliance therewith, there shall be any
increase in the cost to such Lender of agreeing to make or making, funding or maintaining LIBO Rate
Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the
amount received or receivable by such Lender in connection with any of the foregoing (excluding for
purposes of this subsection (a) any such increased costs or reduction in amount resulting
from (i) Taxes or Other Taxes (as to which Section 3.1 shall govern), (ii) changes in the
basis of taxation of overall net income or overall gross income by the United States or any foreign
jurisdiction or any political subdivision of either thereof under the Laws of which such Lender is
organized or has its Lending Office, and (iii) reserve requirements utilized, as to LIBO Rate
Loans, in the determination of the Adjusted LIBO Rate), then from time to time upon demand of such
Lender (with a copy of such demand to the Administrative Agent), the Borrower shall pay to such
Lender such additional amounts as will compensate such Lender for such increased cost or reduction.

     (b) If any Lender determines that the introduction of any Law regarding capital
adequacy or any change therein or in the interpretation thereof, or compliance by such Lender (or
its Lending Office) therewith, has the effect of reducing the rate of return on the capital of such
Lender or any Person controlling such Lender as a consequence of such Lender’s obligations
hereunder (taking into consideration its policies with respect to capital adequacy and such
Lender’s desired return on capital), then from time to time upon demand of such Lender (with a copy
of such demand to the Administrative Agent), the Borrower shall pay to such Lender such additional
amounts as will compensate such Lender for such reduction.

     SECTION 3.5 Funding Losses. Upon demand of any Lender (with a copy to the Administrative
Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such
Lender harmless from any loss, cost or expense incurred by it as a result of:

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

 - 39 -

 

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

     (c) any assignment of a LIBO Rate Loan on a day other than the last day of the
Interest Period therefor as a result of a request by the Borrower pursuant to Section 3.9;

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

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

     SECTION 3.6 Matters Applicable to all Requests for Compensation.

     (a) A certificate of the Administrative Agent or any Lender claiming compensation
under this Article III and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of manifest error. In determining such amount, the
Administrative Agent or such Lender may use any reasonable averaging and attribution methods.

     (b) Upon any Lender’s making a claim for compensation under Section 3.1 or
3.4, the Borrower may remove or replace such Lender in accordance with Section 3.9;
provided that the Borrower shall have the right to replace such Lender only if they also replace
any other Lender who has made or is making a similar claim for compensation under Section
3.1 or 3.4.

     SECTION 3.7 Survival. All of the Borrower’s obligations under this Article III
shall survive termination of the Commitments and of this Agreement and payment in full of all the
other Obligations.

     SECTION 3.8 Foreign Lenders. Each Lender that is a “foreign corporation, partnership or
trust” within the meaning of the Code (a “Foreign Lender”) shall deliver to the
Administrative Agent, prior to receipt of any payment subject to withholding under the Code (or
after accepting an assignment of an interest herein), two duly signed completed copies of either
IRS Form W-8BEN or any successor thereto (relating to such Person and entitling it to an exemption
from, or reduction of, withholding tax on all payments to be made to such Person by the Borrower
pursuant to this Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments
to be made to such Person by the Borrower pursuant to this Agreement) or such other evidence
satisfactory to the Borrower and the Administrative Agent that such Person is entitled to an
exemption from, or reduction of, U.S. withholding tax. Thereafter and from time to time, each such
Person shall (a) promptly submit to the Administrative Agent such additional duly completed and
signed copies of one of such forms (or such successor forms as shall be adopted from time to time
by the relevant United States taxing authorities) as may then be available under then current
United States laws and regulations to avoid, or such evidence as

 - 40 -

 

is satisfactory to the Borrower
and the Administrative Agent of any available exemption from or reduction of, United States
withholding taxes in respect of all payments to be made to such Person by the Borrower pursuant to
this Agreement, (b) promptly notify the Administrative Agent of any change in circumstances
which would modify or render invalid any claimed exemption or reduction, and (c) take such steps as
shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as
may be reasonably necessary (including the re-designation of its Lending Office) to avoid any
requirement of applicable Laws that the Borrower make any deduction or withholding for taxes from
amounts payable to such Person. If such Person fails to deliver the above forms or other
documentation, then the Administrative Agent may withhold from any interest payment to such Person
an amount equivalent to the applicable withholding tax imposed by Sections 1441 and 1442 of the
Code, without reduction. If any Governmental Authority asserts that the Administrative Agent did
not properly withhold any tax or other amount from payments made in respect of such Person, such
Person shall indemnify the Administrative Agent therefor, including all penalties and interest, any
taxes imposed by any jurisdiction on the amounts payable to the Administrative Agent under this
Section, and costs and expenses (including Attorney Costs) of the Administrative Agent. The
obligation of the Lenders under this Section shall survive the payment of all Obligations and the
resignation or replacement of the Administrative Agent.

     SECTION 3.9 Removal and Replacement of Lenders.

     (a) Under any circumstances set forth herein providing that the Borrower shall have
the right to remove or replace a Lender as a party to this Agreement, the Borrower may, upon notice
to such Lender and the Administrative Agent, (i) remove such Lender by terminating such Lender’s
Commitment or (ii) replace such Lender by causing such Lender to assign its Commitment (without
payment of any assignment fee) pursuant to Section 10.7.2(a) to one or more other Lenders
or Eligible Assignees procured by the Borrower; provided, however, that if the
Borrower elects to exercise such right with respect to any Lender pursuant to Section
3.6(b), it shall be obligated to remove or replace, as the case may be, all Lenders that have
made similar requests for compensation pursuant to Section 3.1 or 3.4. The
Borrower shall (x) pay in full all principal, interest, fees and other amounts owing to such Lender
through the date of termination or assignment (including any amounts payable pursuant to
Section 3.5), (y) provide appropriate assurances and indemnities (which may include letters
of credit) to the Issuing Bank as may reasonably be required with respect to any continuing
obligation to purchase participation interests in any L/C Obligations then outstanding, and (z)
release such Lender from its obligations under the Loan Documents. Any Lender being replaced shall
execute and deliver an Lender Assignment with respect to such Lender’s Commitment and outstanding
Credit Extensions. The Administrative Agent shall distribute an amended Schedule 2.1,
which shall be deemed incorporated into this Agreement, to reflect changes in the identities of the
Lenders and adjustments of their respective Commitments and/or Percentage Shares resulting from any
such removal or replacement.

     (b) In order to make all the Lenders’ interests in any outstanding Credit Extensions
ratable in accordance with any revised Percentage Shares after giving effect to the removal or
replacement of a Lender, the Borrower shall pay or prepay, if necessary, on the effective date
thereof, all outstanding Loans of all Lenders, together with any amounts due under Section
3.5. The Borrower may then request Loans from the Lenders in accordance with their revised

 - 41 -

 

Percentage Shares. The Borrower may net any payments required hereunder against any funds being
provided by any Lender or Eligible Assignee replacing a terminating Lender. The effect for
purposes of this Agreement shall be the same as if separate transfers of funds had been made with
respect thereto.

     (c) This section shall supersede any provision in Section 10.1 to the
contrary.

ARTICLE IV.

condition, ordinary wear and tear excepted; (b) make all necessary repairs thereto and renewals and

the occurrence of a Default (A) at least eighty percent (80%) of the present value of the
Borrower’s and the Guarantors’ Oil and Gas Properties constituting proved reserves to which value
is given in the determination of the then current Borrowing Base, (B) after the occurrence of a
Default, at least ninety-five percent (95%) of the present value of the Borrower’s and the
Guarantors’ Oil and Gas Properties, (ii) all of the equity interests of the Borrower or any
Guarantor in any other Guarantor now owned or hereafter acquired by the Borrower or any Guarantor,

respect to the Borrower’s or any Guarantor’s Oil and Gas Properties constituting at least eighty
percent (80%) of the present value, determined by the Lenders in their sole and absolute discretion
and in accordance with their normal practices and standards for oil and gas loans as it exists at
the

- 56 -

 

particular time, of the Borrower’s and the Guarantors’ properties and demonstrating that the

opinions of counsel satisfactory to the Administrative Agent in its sole discretion opining that
the forms of Mortgage are sufficient to create valid first deed of trust or mortgage liens in such
properties and interests and first priority assignments of and security interests in the
Hydrocarbons attributable to such properties and interests and proceeds thereof. In addition and
not by way of limitation of the foregoing, in the case of the Borrower or any Guarantor granting a
Lien in favor of the Administrative Agent upon any assets having a present value in excess of
$1,000,000 located in a new jurisdiction, the Borrower or Guarantor will at its own expense, obtain
and furnish to the Administrative Agent all such opinions of legal counsel as the Administrative
Agent may reasonably request in connection with any such security or instrument.

     (c) Perfection and Protection of Security Interests and Liens. In addition and not by
way of limitation of the foregoing, the Borrower will from time to time deliver, or cause to be
delivered, to the Administrative Agent any financing statements, continuation statements, extension
agreements and other documents, properly completed (and executed and acknowledged when required) by
the Borrower or appropriate Guarantor in form and substance satisfactory to the Administrative
Agent, which the Administrative Agent requests for the purpose of perfecting, confirming, or
protecting any Liens or other rights in the collateral securing any Obligations. In addition to
the foregoing, the Borrower hereby authorizes, and shall cause each Guarantor to authorize, the
Administrative Agent, on behalf of the Issuing Bank and the Lenders, to file in the appropriate
filing office pursuant to applicable Law such financing statements, assignments and continuation
statements as the Administrative Agent shall deem necessary or desirable for the purpose of

any Subsidiary creates, acquires or otherwise forms a Subsidiary, the Borrower shall:

     (i) execute and deliver, or cause the Person owning all of the outstanding equity
interests in such Subsidiary to execute and deliver, as applicable, to the Administrative
Agent on behalf of the Lenders, a Pledge Agreement, or an amendment or

the outstanding equity interests in such Subsidiary shall be pledged to the Administrative
Agent on behalf of the Lenders, together with any certificates representing all equity
interests so pledged, if any, and for each such certificate representing shares of stock, a
stock power executed in blank;

     (ii) cause such Subsidiary to execute and deliver to the Administrative Agent on behalf
of the Lenders (i) a Guaranty, (ii) a ratification and acceptance of the Subordination
Agreement, (iii) an agreement substantially similar to the Security Documents executed and
delivered on the Closing Date and (iv) a Mortgage and a Subordinate Mortgage as to all Oil

Subsidiary;

- 57 -

 

     (iii) cause such Subsidiary to execute and deliver to the Administrative Agent on
behalf of the Lenders and the Issuing Bank, or to authorize the Administrative Agent to file
or record without such Subsidiary’s signature, appropriate financing statements covering the
collateral of such Subsidiary described in the Security Documents required to be delivered
pursuant to the foregoing clauses (i) or (ii);

     (iv) deliver or cause to be delivered to the Administrative Agent on behalf of the
Lenders and the Issuing Bank all agreements, documents, instruments and other writings of
the type described in Section 4.1(a)(iii), (iv) and (vi) with
respect to such Subsidiary and opinions of counsel acceptable to the Administrative Agent
and in form and substance satisfactory to the Administrative Agent covering the matters
covered by the opinions delivered on the Closing Date with respect to such Subsidiary; and

     (v) deliver or cause to be delivered to the Administrative Agent on behalf of the
Lenders all such information regarding the condition (financial or otherwise), business and
operations of such Subsidiary as the Administrative Agent, or the Issuing Bank or any Lender
through the Administrative Agent, may reasonably request.

     (e) Production Proceeds. Notwithstanding that, by the terms of the various Security
Documents, the Loan Parties are and will be assigning to the Administrative Agent, the Issuing Bank
and the Lenders all of the “Production” (as defined therein) and the proceeds therefrom accruing to
the properties covered thereby, so long as no Event of Default has occurred, the Loan Parties may
continue to receive from the purchasers of production all such Production Proceeds, subject,
however, to the Liens created under the Security Documents, which Liens are hereby affirmed and
ratified. Upon the occurrence of an Event of Default, the Administrative Agent, the Issuing Bank
and the Lenders may exercise all rights and remedies granted under the Security Documents,
including the right to obtain possession of all Production Proceeds then held by any Loan Party or
to receive directly from the purchasers of production all other Production Proceeds. In no case
shall any failure, whether purposeful or inadvertent, by the Administrative Agent, the Issuing Bank
or the Lenders to collect directly any such Production Proceeds constitute in any way a waiver,
remission or release of any of its or their rights under the Security Documents, nor shall any
release of any Production Proceeds by the Administrative Agent or Lenders to any Loan Party
constitute a waiver, remission, or release of any other
Production Proceeds or of any rights of the Administrative Agent, the Issuing Bank or the
Lenders to collect other Production Proceeds thereafter.

     SECTION 6.16 Limitation on Hedges. The Borrower shall not, and shall not permit any Subsidiary of
the Borrower to, enter into any commodity hedging or derivative transactions except Hedge
Agreements related to bona fide hedging activities of the Borrower (and not for speculative
purposes) in an aggregate notional amount not to exceed, with respect to any future calendar
quarter, 75% of the Borrower’s (and its Subsidiaries) projected proved, developed producing
production of oil (for oil related transactions) and 75% of the Borrower’s (and its Subsidiaries)
projected proved, developed producing production of natural gas (for natural gas related
transactions), in each case, from the Borrower’s Oil and Gas Properties.

ARTICLE IX.

ADMINISTRATIVE AGENT

     SECTION 9.1 Appointment and Authorization of Administrative Agent.

     (a) Each Lender hereby irrevocably (subject to Section 9.9) appoints, designates and
authorizes the Administrative Agent to take such action on its behalf under the provisions of this
Agreement and each other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan Document, together with
such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have
any duties or responsibilities, except those expressly set forth herein, nor shall the
Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or
participant, and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against
the Administrative Agent. Without limiting the generality of the foregoing sentence, the use of
the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent
is not intended to connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable law. Instead, such term is used merely as a matter of market
custom, and is intended to create or reflect only an administrative relationship between
independent contracting parties. Each Lender hereby agrees to assert no claim against the
Administrative Agent on any agency theory or any other theory of liability for breach of fiduciary
duty, all of which claims are hereby expressly waived by each Lender.

     (b) The Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit
issued by it and the documents associated therewith until such time (and except for so

- 67 -

 

long) as the
Administrative Agent may agree at the request of the Majority Lenders to act for the Issuing Bank
with respect thereto; provided, however, that the Issuing Bank shall have all of
the benefits and immunities (i) provided to the Administrative Agent in this Article IX
with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters
of Credit issued by it or proposed to be issued by it and the application and agreements for
letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative
Agent” as used in this Article IX included the Issuing Bank with respect to such acts or
omissions, and (ii) as additionally provided herein with respect to the Issuing Bank.

     SECTION 9.2 Delegation of Duties. The Administrative Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees or attorneys-in-fact and
shall be entitled to advice of counsel and other consultants or experts concerning all matters
pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or
misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or
willful misconduct.

     SECTION 9.3 Liability of Administrative Agent. No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any
of them under or in connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct in connection with
its duties expressly set forth herein), or (b) be responsible in any manner to any Lender or
participant for any recital, preliminary statement, statement, representation or warranty made by
any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or any other Loan Document, or the
validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other
Loan Document, or for any failure of any Loan Party or any other party to any Loan Document to
perform its obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender or participant to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this Agreement or any other
Loan Document, or to inspect the properties, books or records of any Loan Party or any Affiliate
thereof.

     SECTION 9.4 Reliance by Administrative Agent.

     (a) The Administrative Agent shall be entitled to rely, and shall be fully protected in
relying, upon any writing, communication, signature, resolution, representation, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message, statement or other
document or conversation believed by it to be genuine and correct and to have been signed, sent or
made by the proper Person or Persons, and upon advice and statements of legal counsel (including
counsel to any Loan Party), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to
take any action under any Loan Document unless it shall first receive such advice or concurrence of
the Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified
to its satisfaction by the Lenders against any and all liability and expense which may be incurred
by it by reason of taking or continuing to take any such action. The Administrative Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this Agreement or any

- 68 -

 

other Loan Document in accordance with a request or consent of the Majority Lenders or all the
Lenders, if required hereunder, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders and participants. Where this Agreement expressly
permits or prohibits an action unless the Majority Lenders otherwise determine, the Administrative
Agent shall, and in all other instances, the Administrative Agent may, but shall not be required
to, initiate any solicitation for the consent or a vote of the Lenders.

     (b) For purposes of determining compliance with the conditions specified in Section
4.1, each Lender that has signed this Agreement shall be deemed to have consented to, approved
or accepted or to be satisfied with, each document or other matter either sent by the
Administrative Agent to such Lender for consent, approval, acceptance or satisfaction, or required
thereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

     SECTION 9.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of
any Default or Event of Default, except with respect to defaults in the payment of principal,
interest and fees required to be paid to the Administrative Agent for the account of the Lenders,
unless the Administrative Agent shall have received written notice from a Lender or the Borrower
referring to this Agreement, describing such Default or Event of Default and stating that such
notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt
of any such notice. The Administrative Agent shall take such action with respect to such Default
or Event of Default as may be directed by the Majority Lenders in accordance with Article
VIII; provided, however, that unless and until the Administrative Agent has
received any such direction, the Administrative Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or Event of Default as it
shall deem advisable or in the best interest of the Lenders.

     SECTION 9.6 Credit Decision; Disclosure of Information by Administrative Agent. Each Lender
acknowledges that no Agent-Related Person has made any representation or warranty to it, and that
no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of
any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed
to constitute any representation or warranty by any Agent-Related Person to any Lender as to any
matter, including whether Agent-Related Persons have disclosed material information in their
possession. Each Lender represents to the Administrative Agent that it has, independently and
without reliance upon any Agent-Related Person and based on such documents and information as it
has deemed appropriate, made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the Loan Parties and
their respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the
transactions contemplated hereby, and made its own decision to enter into this Agreement and to
extend credit to the Borrower hereunder. Each Lender also represents that it will, independently
and without reliance upon any Agent-Related Person and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and
decisions in taking or not taking action under this Agreement and the other Loan Documents, and to
make such investigations as it deems necessary to inform itself as to the business, prospects,
operations, property, financial and other condition and creditworthiness of the Borrower and the
other Loan Parties. Except for notices, reports and other documents expressly required to be
furnished to the Lenders by the

- 69 -

 

Administrative Agent herein, the Administrative Agent shall not
have any duty or responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, property, financial and other condition or
creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come
into the possession of any Agent-Related Person.

     SECTION 9.7 Indemnification of Administrative Agent. Whether or not the transactions contemplated
hereby are consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the
extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any
Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any
and all Indemnified Liabilities incurred by it (INCLUDING ANY AND ALL INDEMNIFIED LIABILITIES ARISING OUT OF, IN ANY
WAY RELATING TO, OR RESULTING FROM SUCH AGENT-RELATED PARTY’S OWN NEGLIGENCE OR STRICT LIABILITY);
provided, however, that no Lender shall be liable for the payment to any
Agent-Related Person of any portion of such Indemnified Liabilities resulting from such
Agent-Related Person’s gross negligence or willful misconduct; provided, however,
that no action taken in accordance with the directions of the Majority Lenders shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section. Without limitation
of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable
share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the
Administrative Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any
other Loan Document, or any document contemplated by or referred to herein, to the extent that the
Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The
undertaking in this Section shall survive termination of the Commitments, the payment of all
Obligations hereunder and the resignation or replacement of the Administrative Agent.

     SECTION 9.8 Administrative Agent in its Individual Capacity. Scotia Capital and its Affiliates may
make loans to, issue letters of credit for the account of, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with each of the Loan Parties and their respective Affiliates as though Scotia
Capital were not the Administrative Agent or the Issuing Bank hereunder and without notice to or
consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Scotia Capital
or its Affiliates may receive information regarding any Loan Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such Loan Party or such
Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide
such information to them. With respect to its Loans, Scotia Capital shall have the same rights and
powers under this Agreement as any other Lender and may exercise such rights and powers as though
it were not the Administrative Agent or the Issuing Bank, and the terms “Lender” and “Lenders”
include Scotia Capital in its individual capacity.

     SECTION 9.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative
Agent upon 30 days’ notice to the Lenders. If the Administrative Agent resigns under this
Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative
agent for the Lenders. If no successor administrative agent is appointed

- 70 -

 

prior to the effective
date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after
consulting with the Lenders, a successor administrative agent from among the Lenders. Upon the
acceptance of its appointment as successor administrative agent hereunder, such successor
administrative agent shall succeed to all the rights, powers and duties of the retiring
Administrative Agent and the term “Administrative Agent” shall mean such successor administrative
agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative
Agent shall be terminated. After any retiring Administrative Agent’s resignation hereunder as
Administrative Agent, the provisions of this Article IX and Sections 10.4 and 10.5 shall
inure to its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor administrative agent has accepted
appointment as Administrative Agent by the date which is 30 days following a retiring
Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor
agent as provided for above.

     SECTION 9.10 Other Agents; Lead Managers. None of the Lenders identified on the facing page or
signature pages of this Agreement as a “syndication agent,” “documentation agent,” “co-agent” or
“lead manager” shall have any right, power, obligation, liability, responsibility or duty under
this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing,
none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with
any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders so identified in deciding to enter into this Agreement or in taking or not taking action
hereunder.

ARTICLE X.

     SECTION 10.3 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

and the consummation and administration of the transactions
contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or reimburse the
Administrative Agent and each Lender for all costs and expenses incurred in connection with the

(a) any and all claims, demands, actions or causes of action that are asserted against any
Indemnitee by any Person (other than the Administrative Agent or any Lender) relating directly or
indirectly to a claim, demand, action or cause of action that such Person asserts or may assert
against any Loan Party, any Affiliate of any Loan Party or any of their respective officers or
directors; (b) any and all claims, demands, actions or causes of action that may at any time
(including at any time following repayment of the Obligations and the resignation or removal of the

relationship of any Loan Party, the Administrative Agent and the Lenders under this Agreement or
any other Loan Document; (c) any administrative or investigative proceeding by any Governmental
Authority arising out of or related to a claim, demand, action or cause of action described in

suffers or incurs as a result of the assertion of any foregoing claim, demand, action, cause of
action, litigation or proceeding, or as a result of the preparation of any defense in connection
with any foregoing claim, demand, action, cause of action, litigation or proceeding, in all cases,
WHETHER OR NOT ARISING OUT OF THE NEGLIGENCE OF AN INDEMNITEE OR STRICT LIABILITY, AND WHETHER OR
NOT AN INDEMNITEE IS A PARTY TO SUCH CLAIM, DEMAND, ACTION, CAUSE OF ACTION, LITIGATION OR
PROCEEDING (ALL THE FOREGOING, COLLECTIVELY, THE “INDEMNIFIED LIABILITIES”);
PROVIDED THAT NO INDEMNITEE SHALL BE ENTITLED TO INDEMNIFICATION FOR ANY CLAIM CAUSED BY
ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OR FOR ANY LOSS ASSERTED AGAINST IT BY ANOTHER
INDEMNITEE. THE AGREEMENTS IN THIS SECTION SHALL SURVIVE THE TERMINATION OF THE COMMITMENTS AND
REPAYMENT OF ALL THE OTHER OBLIGATIONS.

     SECTION 10.6 Payments Set Aside. To the extent that the Borrower makes a payment to the
Administrative Agent or any Lender, or the Administrative Agent or any Lender

exercises its right
of set-off, and such payment or the proceeds of such set-off 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 Person, 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 set-off had not occurred, and (b) each Lender
severally agrees to pay to the Administrative Agent upon demand its applicable share 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 (i) with respect
to the first two Business Days following such demand, the lesser of (x) the Federal Funds Rate and
(y) the Highest Lawful Rate, in each case, from time to time in effect, and (2) with respect to
each day thereafter, the lesser of (x) the Base Rate and (y) the Highest Lawful Rate, in each case,
from time to time in effect.

     SECTION 10.7 Successors and Assigns; Assignments; Participations.

     10.7.1 Successors and Assigns. The provisions of this Agreement and the other Loan
Documents 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 each
Lender (and any attempted assignment or transfer by the Borrower without such consent 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
and, to the extent expressly contemplated hereby, the Indemnitees) any legal or equitable right,
remedy or claim under or by reason of this Agreement.

     10.7.2 Assignments.

     (a) Any Lender may 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
(including in all instances for purposes of this subsection (a), participations in L/C
Obligations) 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, the
aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder,
including as noted above, participations in L/C Obligations) subject to each such assignment,
determined as of the date the Lender Assignment with respect to such assignment is delivered to the
Administrative Agent, shall not be less than $5,000,000 unless each of the Administrative
Agent and, so long as no Default has occurred and is continuing and so long as in the case of The
Bank of Nova Scotia, such Lender shall have been reduced to its “final hold amount” as described in
the commitment letter referred to in the Agent and Arranger Fee Letter, 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 or the Commitment assigned,
except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its
rights and obligations among separate Borrowings on a non-pro rata basis, (iii) the parties

- 75 -

 

to each
assignment shall execute and deliver to the Administrative Agent a Lender Assignment, together with
a processing and recordation fee of $3,500. 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 Lender Assignment, the Eligible Assignee thereunder shall be a
party hereto and, to the extent of the interest assigned by such Lender Assignment, have the rights
and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Lender Assignment, be released from its obligations under
this Agreement (and, in the case of an Lender Assignment 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 Sections 3.7, 10.4 and 10.5).
Upon request, the Borrower (at its expense) shall execute and deliver new or replacement Notes to
the assigning Lender and 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.

     (b) 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 Lender Assignment delivered to
it and a register for the recordation of the names and addresses of the Lenders, and the
Commitments of, and principal amount of the Loans and L/C Obligations 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 by the Borrower and any Lender, at any reasonable time and from
time to time upon reasonable prior notice.

     10.7.3 Participations.

     (a) Any Lender may, without the consent of, or notice to, the Borrower or the Administrative
Agent, sell participations to one or more banks or other entities (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 (including such Lender’s participations in L/C
Obligations) 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 other Lenders shall continue to deal solely and directly with such Lender in connection with
such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to
which a Lender sells such a participation shall provide that such Lender shall retain the sole
right to enforce this Agreement and to approve any amendment, modification or waiver of any
provision of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any amendment, waiver or
other modification that would (i) postpone any date upon which any payment of money is scheduled to
be paid to such Participant, (ii) reduce the principal, interest, fees or other amounts payable to
such Participant, or (iii) release any Guarantor from the Guaranty. Subject to subsection
(b) of this Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 3.1, 3.4 and 3.5 to the same extent as if it were a
Lender and had acquired its interest by

- 76 -

 

assignment pursuant to Section 10.7.2. To the
extent permitted by law, each Participant also shall be entitled to the benefits of Section
10.9 as though it were a Lender, provided such Participant agrees to be subject to
Section 2.14 as though it were a Lender.

     (b) A Participant shall not be entitled to receive any greater payment under Section
3.1 or 3.4 than the applicable Lender would have been entitled to receive with respect
to the participation sold to such Participant, unless the sale of the participation to such
Participant is made with the Borrower’s prior written consent. A Participant that would be a
Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.1
unless the Borrower is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 3.8 as though it were a
Lender.

     10.7.4 Pledge of Lender’s Interest. Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement (including under its Notes, 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 a
Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such
Lender as a party hereto.

     10.7.5 Consent to Assignment. If the consent of the Borrower to an assignment or to an
Eligible Assignee is required hereunder (including a consent to an assignment which does not meet
the minimum assignment threshold specified in clause (i) of the proviso to the first sentence of
Section 10.7.2, the Borrower shall be deemed to have given its consent five Business Days
after the date notice thereof has been delivered by the assigning Lender (through the
Administrative Agent) unless such consent is expressly refused by the Borrower prior to such fifth
Business Day.

     10.7.6 Definitions for Section 10.7. As used herein, the following term has the following
meaning:

“Eligible Assignee” means (a) a Lender; (b) an Affiliate of
a Lender; and (c) any other Person (other than a natural Person)
approved by the Administrative Agent (which approval shall not be
unreasonably withheld or delayed) and the Issuing Bank.

     10.7.7 Assignment by Scotia Capital. Notwithstanding anything to the contrary contained
herein, if at any time Scotia Capital assigns all of its Commitment and Loans pursuant to
Section 10.7.2, Scotia Capital may, upon 30 days’ notice to the Borrower and the Lenders,
resign as Issuing Bank. In the event of any such resignation as Issuing Bank, the Borrower shall
be entitled to appoint from among the Lenders a successor Issuing Bank hereunder; provided,
however, that no failure by the Borrower to appoint any such successor shall affect the
resignation of Scotia Capital as Issuing Bank. Scotia Capital shall retain all the rights and
obligations of the Issuing Bank hereunder with respect to all Letters of Credit outstanding as of
the effective date of its resignation as Issuing Bank and all L/C Obligations with respect thereto
(including the right to require the Lenders to make Base Rate Loans or fund participations in
Unreimbursed Amounts pursuant to Section 2.3.3).

- 77 -

 

     SECTION 10.8 Confidentiality. (a) 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 and its Affiliates’ directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such Information and instructed
to keep such Information confidential); (b) to the extent requested by any regulatory authority;
(c) to the extent required by applicable laws or regulations or by any subpoena or similar legal
process; (d) to any other party to this Agreement; (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement
of rights hereunder; (f) subject to an agreement containing provisions substantially the same as
those of this Section, to (i) any Eligible Assignee of or Participant in, or any prospective
Eligible Assignee of or Participant in, any of its rights or obligations under this Agreement or
(ii) any direct or indirect contractual counterparty or prospective counterparty (or such
contractual counterparty’s or prospective counterparty’s professional advisor) to any credit
derivative transaction relating to obligations of the Borrower; (g) with the consent of the
Borrower; (h) to the extent such Information (i) becomes publicly available other than as a result
of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on
a nonconfidential basis from a source other than the Borrower; or (i) to the National Association
of Insurance Commissioners or any other similar organization or any nationally recognized rating
agency that requires access to information about a Lender’s or its Affiliates’ investment portfolio
in connection with ratings issued with respect to such Lender or its Affiliates. For the purposes
of this Section, “Information” means all information received from the Borrower relating to the
Borrower or its business, 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; provided that,
in the case of information received from the Borrower after the date hereof, such information is
clearly identified in writing 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.

     SECTION 10.9 Set-off. In addition to any rights and remedies of the Lenders provided by law, upon the occurrence and
during the continuance of any Event of Default, each Lender is authorized at any time and from time
to time, without prior notice to the Borrower or any other Loan Party, any such notice being waived
by the Borrower (on its own behalf and on behalf of each Loan Party) to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender
to or for the credit or the account of the respective Loan Parties against any and all Obligations
owing to such Lender, now or hereafter existing, irrespective of whether or not the Administrative
Agent or such Lender shall have made demand under this Agreement or any other Loan Document and
although such Obligations may be contingent or unmatured. Each Lender agrees promptly to notify
the Borrower and the Administrative Agent after any such set-off and application made by such
Lender; provided, however, that the failure to give such notice shall not affect
the validity of such set-off and application.

- 78 -

 

     SECTION 10.10 Interest Rate Limitation. All agreements between the Borrower, the Administrative
Agent, the Issuing Bank, or any Lender under or in connection with the Loan Documents, whether now
existing or hereafter arising and whether written or oral, are hereby expressly limited so that in
no contingency or event whatsoever, whether by reason of demand being made in respect of an amount
due under any Loan Document or otherwise, shall the amount paid, or agreed to be paid, to the
Administrative Agent, the Issuing Bank, or any Lender for the use, forbearance, or detention of the
money to be loaned under this Agreement, any Notes or any other Loan Document or otherwise or for
the payment or performance of any covenant or obligation contained herein or in any other Loan
Document exceed the Highest Lawful Rate. If, as a result of any circumstances whatsoever,
fulfillment of any provision hereof or of any of such documents, at the time performance of such
provision shall be due, shall involve transcending the limit of validity prescribed by applicable
usury law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if, from any such circumstance, the Administrative Agent, the Issuing Bank, or any
Lender shall ever receive interest or anything that might be deemed interest under applicable law
that would exceed the Highest Lawful Rate, such amount that would be excessive interest shall be
applied to the reduction of the principal amount owing on account of such Lender’s Loans or the
amounts owing on other obligations of the Borrower to the Administrative Agent, the Issuing Bank,
or any Lender under any Loan Document and not to the payment of interest, or if such excessive
interest exceeds the unpaid principal balance of such Lender’s Loans and the amounts owing on other
obligations of the Borrower to the Administrative Agent or any Lender under any Loan Document, as
the case may be, such excess shall be refunded to the Borrower. All sums paid or agreed to be paid
to the Administrative Agent or any Lender for the use, forbearance or detention of the indebtedness
of the Borrower to the Administrative Agent or any Lender shall, to the fullest extent permitted by
applicable law, be amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full of the principal (including the period of any renewal or
extension thereof) so that the interest on account of such indebtedness shall not exceed the
Highest Lawful Rate. Notwithstanding anything to the contrary contained in any Loan Document, it is
understood and agreed that if at any time the rate of interest that accrues on the outstanding
principal balance of any Loan or other amounts owed shall exceed the Highest Lawful Rate, the rate
of interest that accrues on the outstanding principal balance of any Loan shall be limited to the
Highest Lawful Rate, but any subsequent reductions in the rate of interest that accrues on the outstanding
principal balance of any Loan shall not reduce the rate of interest that accrues on the outstanding
principal balance of any Loan or other amounts below the Highest Lawful Rate until the total amount
of interest accrued on the outstanding principal balance of any Loan or other amounts equals the
amount of interest that would have accrued if such interest rate had at all times been in effect.
The terms and provisions of this Section 10.10 shall control and supersede every other
provision of all Loan Documents. For purposes of Tex. Fin. Code Ann. Ch. 303, as amended, to the
extent, if any, applicable to a Lender or the Issuing Bank, the Borrower agrees that the Highest
Lawful Rate shall be the “weekly ceiling” as defined in said Article, provided that such
Lender and the Issuing Bank may also rely, to the extent permitted by applicable laws, on
alternative maximum rates of interest under other laws applicable to such Lender or such Issuer, as
the case may be, if greater. Tex. Fin. Code Ann. Ch. 346 (which regulates certain revolving credit
loan accounts and revolving tri-party accounts) shall not apply to this Agreement or the Notes.

- 79 -

 

     SECTION 10.11 Counterparts. This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute one and the same
instrument.

     SECTION 10.12 Survival of Representations and Warranties. All representations and warranties made
hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or
in connection herewith or therewith shall survive the execution and delivery hereof and thereof.
Such representations and warranties have been or will be relied upon by the Administrative Agent
and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or
on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice
or knowledge of any Default or Event of Default at the time of any Credit Extension, and shall
continue in full force and effect as long as any Loan or any other Obligation shall remain unpaid
or unsatisfied or any Letter of Credit shall remain outstanding.

     SECTION 10.13 Collateral Matters; Hedges. The benefit of the Security Documents and the provisions
of this Agreement and the other Loan Documents relating to the collateral shall also extend to and
be available on a pro rata basis to each Lender and such Lender’s Affiliates in respect of any
obligations under a Hedging Agreement only so long as such Lender remains a party to this Agreement
and this Agreement remains in effect. No Lender or Affiliate of a Lender shall have any voting or
consent right under any Loan Document as a result of the existence of obligations owed to it under
a Hedging Agreement.

     SECTION 10.14 [Intentionally Deleted].

     SECTION 10.15 Severability. Any provision of this Agreement and the other Loan Documents to which the Borrower is a party
that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without invalidating the
remaining provisions thereof, and any such prohibition or unenforceability in any jurisdiction
shall not invalidate or render unenforceable such provision in any other jurisdiction.

     SECTION 10.16 Governing Law.

     (a) THIS 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).

     (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS SITTING IN HOUSTON, TEXAS OR OF THE UNITED
STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT,
THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN

- 80 -

 

RESPECT OF ITS
PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, THE ADMINISTRATIVE
AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF
VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER
DOCUMENT RELATED THERETO. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER WAIVES PERSONAL
SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED
BY THE LAW OF SUCH STATE.

     SECTION 10.17 Waiver of Right to Trial by Jury. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY
WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY
LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES
HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN
EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR
OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE
OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY
FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS
WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY
JURY.

     SECTION 10.18 Consents to Renewals, Modifications and Other Actions and Events. This Agreement and
all of the obligations of the Borrower hereunder shall remain in full force and effect without
regard to and shall not be released, affected or impaired by: (a) any amendment, assignment,
transfer, modification of or addition or supplement to the Lenders Obligations, this Agreement, any
Note or any other Loan Document; (b) any extension, indulgence, increase in the Lenders Obligations
or other action or inaction in respect of any of the Loan Documents or otherwise with respect to
the Lenders Obligations, or any acceptance of security for, or guaranties of, any of the Lenders
Obligations or Loan Documents, or any surrender, release, exchange, impairment or alteration of any
such security or guaranties including without limitation the failing to perfect a security interest
in any such security or abstaining from taking advantage or of realizing upon any guaranties or
upon any security interest in any such security; (c) any default by the Borrower under, or any lack
of due execution, invalidity or unenforceability of, or any irregularity or other defect in, any of
the Loan Documents; (d) any waiver by the Lenders or any other Person of any required performance
or otherwise of any condition precedent or waiver of any requirement imposed by any of the Loan
Documents, any guaranties or otherwise with respect to the Lenders Obligations; (e) any exercise or
non-exercise of any right, remedy, power or privilege in respect of this Agreement or any of the
other Loan Documents; (f) any sale, lease, transfer or other disposition of the assets of the
Borrower or any consolidation or merger of the Borrower with or into any other Person, corporation,
or entity, or any transfer or other disposition by the Borrower or any other holder of any shares
of capital stock or other ownership interest of the Borrower; (g) any bankruptcy,

- 81 -

 

insolvency,
reorganization or similar proceedings involving or affecting the Borrower; (h) the release or
discharge of the Borrower from the performance or observance of any agreement, covenant, term or
condition under any of the Obligations or contained in any of the Loan Documents by operation of
law; or (i) any other cause whether similar or dissimilar to the foregoing which, in the absence of
this provision, would release, affect or impair the Obligations, covenants, agreements and duties
of the Borrower hereunder, including without limitation any act or omission by the Administrative
Agent, or the Lenders or any other Person which increases the scope of the Borrower’s risk; and in
each case described in this paragraph whether or not the Borrower shall have notice or knowledge of
any of the foregoing, each of which is specifically waived by the Borrower. The Borrower warrants
to the Administrative Agent and the Lenders that it has adequate means to obtain from the
Guarantors on a continuing basis information concerning the financial condition and other matters
with respect to the Guarantors and it is not relying on the Administrative Agent or the Lenders to
provide such information either now or in the future.

     SECTION 10.19 ENTIRE AGREEMENT. This Agreement, together with the other Loan Documents, comprises
the complete and integrated agreement of the parties on the subject matter hereof and thereof and
supersedes all prior agreements, written or oral, on such subject matter. THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN
THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
