ARTICLE II

CREDIT FACILITIES

     Section 2.1. Commitment for Advances.

     (a) Advances. Each Bank severally agrees, on the terms and conditions set forth in
this Agreement, to make Advances to the Borrower from time to time on any Business Day

- 17 -

 

during the period from the date of this Agreement until the Maturity Date in an aggregate
outstanding amount up to but not to exceed an amount equal to (i) the lesser of such Bank’s
Commitment or such Bank’s Pro Rata Share of the Borrowing Base less (ii) such Bank’s Pro
Rata Share of the Letter of Credit Exposure; provided that the sum of the outstanding amount of all
Advances made by such Bank and such Bank’s Pro Rata Share of the Letter of Credit Exposure shall
not exceed such Bank’s Commitment. Each Borrowing shall, in the case of Borrowings consisting of
Base Rate Advances, be in an aggregate amount not less than $500,000 and in integral multiples of
$100,000 in excess thereof, and in the case of Borrowings consisting of Eurodollar Rate Advances,
be in an aggregate amount not less than $2,000,000 or in integral multiples of $1,000,000 in excess
thereof, and in each case shall consist of Advances of the same Type made on the same day by the
Banks ratably according to their respective Commitments. Within the limits of each Bank’s
Commitment, and subject to the terms of this Agreement, the Borrower may from time to time borrow,
prepay, and reborrow Advances.

     (b) Optional Reduction of Commitment. The Borrower shall have the right, upon at
least three Business Days’ irrevocable notice to the Agent, to terminate in whole or reduce ratably
in part the unused portion of the Commitments; provided that each partial reduction of the
Commitments shall be in the aggregate amount of $5,000,000 or in integral multiples of $1,000,000
in excess thereof. Any reduction or termination of the Commitments pursuant to this
Section 2.1(b) shall be permanent, with no obligation of the Banks to reinstate such
Commitments, and the commitment fees provided for in Section 2.7(a) shall thereafter be
computed on the basis of the Commitments, as so reduced.

     (c) Notes. The indebtedness of any Borrower to each Bank resulting from the Advances
owing to such Bank shall, if such Bank requests, be evidenced by a Note of the Borrower in the
maximum principal amount of such Bank’s Commitment.

     Section 2.2. Borrowing Base.

     (a) The Borrowing Base has been set by the Banks and acknowledged by the Borrower as
$700,000,000, as of the date hereof.

     (b) From the date hereof through the Maturity Date and subject to the further provisions of
this Section 2.2, the Borrowing Base shall be redetermined by the Majority Banks each May 1
and November 1 in accordance with Section 2.2(d) on the basis of information, including the
Oil and Gas Reserve Reports required to be delivered before each such date supplied by Borrower in
compliance with the provisions of this Agreement, such additional data concerning pricing,
quantities of production, purchasers of production, and other information and engineering and
geological data with respect thereto as the Agent or any Bank may reasonably request, together with
all other information then available to the Agent and the Banks; provided that the first such
scheduled redetermination shall occur on November 1, 2008. Notwithstanding the foregoing, the
Majority Banks may, in the exercise of their good faith discretion, require additional
redeterminations of the Borrowing Base in accordance with Section 2.2(d) (i) by providing
written notice to the Borrower, but only two such requests may be made during any calendar year and
(ii) from time to time upon the occurrence of any Material Adverse Change.

- 18 -

 

     (c) The Borrower may request that the Majority Banks redetermine the Borrowing Base (i) by
providing a written request to the Agent, but only two such requests may be made during any
calendar year or (ii) in connection with the Borrower’s or any Guarantor’s acquisition of Oil and
Gas Properties with a purchase price of $20,000,000 or more. In connection with any such request,
the Borrower shall provide the Agent and the Banks with an interim reserve report prepared by the
Borrower together with such other information, including additional data concerning pricing,
quantities of production, purchasers of production, and other information and engineering and
geological data, as the Agent or any Bank may reasonably request. Within 30 days following the
receipt of such interim reserve report and other information, the Majority Banks shall make a
redetermination of the Borrowing Base in accordance with Section 2.2(d).

     (d) In connection with a redetermination of the Borrowing Base, the Agent shall propose a
Borrowing Base to the Banks, and the Banks shall vote to approve or disapprove such proposed
Borrowing Base. If the Majority Banks do not approve the proposed Borrowing Base, the Agent shall
propose, and the Banks shall vote to approve or disapprove, another Borrowing Base, until the
Majority Banks approve a Borrowing Base proposed by the Agent. Once the Majority Banks approve the
proposed Borrowing Base, the Agent shall notify the Borrower of such redetermination. Until the
Borrower receives such notification from the Agent, the Borrowing Base most recently established
shall remain in effect, and thereafter the new Borrowing Base as set forth in such notification
shall be in effect.

     (e) Upon any sale, lease, transfer, or other disposition, whether or not in the ordinary
course of business, by the Borrower or any of its Subsidiaries of Borrowing Base Assets that
(individually or on a cumulative basis with all such dispositions consummated since the
determination of the most recently determined Borrowing Base) were given value in the most recently
determined Borrowing Base in excess of 5% of the amount of such Borrowing Base, the Borrowing Base
shall automatically be reduced by the present value given to such assets in the most recent
engineering report delivered pursuant to Section 5.6(c), including the applicable stated
discount utilized therein.

     (f) The Borrowing Base shall represent the determination by the Majority Banks of the loan
value of the Borrower’s and the Guarantors’ Oil and Gas Properties which are either (i) subject to
an Acceptable Security Interest or (ii) unencumbered (except for Permitted Borrowing Base Liens),
but the Agent and the Majority Banks shall make their determination and vote their approval,
respectively, in accordance with the applicable definitions and provisions herein contained, each
such Bank’s standard policies regarding energy lending, industry lending practices, consultation
with the Agent and the other Banks (but without requiring the approval of any such Bank), and
consideration for the nature of the facilities established hereunder. The Borrower acknowledges
that the determination of the Borrowing Base contains an equity cushion (market value in excess of
loan value), which is acknowledged by Borrower to be essential for the adequate protection of the
Agent and the Banks.

     (g) The Borrower shall also have the right to reduce the Borrowing Base once during the period
from October 1 to March 31 and once during the period from April 1 to September 30 during each year
by providing the Agent 30 days advance written notice of such reduction. The Agent shall promptly
send to each Bank a copy of such notice and such reduction shall be effective on the date of the
Agent’s receipt of such notice.

- 19 -

 

     (h) As of the date of this Agreement, the Agent has provided the Borrower with the Agent’s
standard policies regarding energy lending. The Agent, but not any other Bank, agrees to provide
the Borrower with written notice of any changes to such policies.

     Section 2.3. Method of Borrowing.

     (a) Notice. Each Borrowing shall be made pursuant to a Notice of Borrowing (or by
telephone notice promptly confirmed in writing by a Notice of Borrowing), given not later than
10:00 a.m. (Dallas, Texas time) (i) on the third Business Day before the date of the proposed
Borrowing, in the case of a Eurodollar Rate Borrowing or (ii) on the Business Day of the proposed
Borrowing, in the case of a Base Rate Borrowing, by the Borrower to the Agent, which shall in turn
give to each Bank prompt notice of such proposed Borrowing by telecopier or telex. Each Notice of
a Borrowing shall be given by telecopier or telex, confirmed immediately in writing specifying the
information required therein. In the case of a proposed Borrowing comprised of Eurodollar Rate
Advances, the Agent shall promptly notify each Bank of the applicable interest rate under
Section 2.8(b). Each Bank shall (A) in the case of a Eurodollar Rate Borrowing, before
10:00 a.m. (Dallas, Texas time) on the date of such Borrowing and (B) in the case of a Base Rate
Borrowing, before 12:00 noon (Dallas, Texas time) on the date of such Borrowing, make available for
the account of its Applicable Lending Office to the Agent at its address referred to in
Section 9.2, or such other location as the Agent may specify by notice to the Banks, in
same day funds, such Bank’s Pro Rata Share of such Borrowing. After the Agent’s receipt of such
funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent shall
make such funds available to the Borrower at its account with the Agent.

     (b) Conversions and Continuations. The Borrower may elect to Convert or continue any
Borrowing under this Section 2.3 by delivering an irrevocable Notice of Conversion or
Continuation to the Agent at the Agent’s office no later than 10:00 a.m. (Dallas, Texas time)
(i) on the date which is at least three Business Days in advance of the proposed Conversion or
continuation date in the case of a Conversion to or a continuation of a Borrowing comprised of
Eurodollar Rate Advances and (ii) on the Business Day of the proposed conversion date in the case
of a Conversion to a Borrowing comprised of Base Rate Advances. Each such Notice of Conversion or
Continuation shall be in writing or by telex or telecopier confirmed immediately in writing
specifying the information required therein. Promptly after receipt of a Notice of Conversion or
Continuation under this Section, the Agent shall provide each Bank with a copy thereof and, in the
case of a Conversion to or a Continuation of a Borrowing comprised of Eurodollar Rate Advances,
notify each Bank of the applicable interest rate under Section 2.8(b).

     (c) Certain Limitations. Notwithstanding anything in paragraphs (a) and (b) above:

     (i) at no time shall there be more than twelve Interest Periods applicable to
outstanding Eurodollar Rate Advances;

     (ii) if any Bank shall, at least one Business Day before the date of any requested
Borrowing, Conversion, or continuation, notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful, or that any
central bank or other Governmental Authority asserts that it is unlawful, for such Bank or
its Eurodollar Lending Office to perform its obligations under this Agreement to

- 20 -

 

make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances, the
right of the Borrower to select Eurodollar Rate Advances from such Bank shall be suspended
until such Bank shall notify the Agent that the circumstances causing such suspension no
longer exist, and the Advance made by such Bank in respect of such Borrowing, Conversion, or
continuation shall be a Base Rate Advance;

     (iii) if the Agent is unable to determine the Eurodollar Rate for Eurodollar Rate
Advances comprising any requested Borrowing, the right of the Borrower to select Eurodollar
Rate Advances for such Borrowing or for any subsequent Borrowing shall be suspended until
the Agent shall notify the Borrower and the Banks that the circumstances causing such
suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate
Advance;

     (iv) if the Majority Banks shall, at least one Business Day before the date of any
requested Borrowing, notify the Agent that the Eurodollar Rate for Eurodollar Rate Advances
comprising such Borrowing will not adequately reflect the cost to such Banks of making or
funding their respective Eurodollar Rate Advances, as the case may be, for such Borrowing,
the right of the Borrower to select Eurodollar Rate Advances for such Borrowing or for any
subsequent Borrowing shall be suspended until the Agent shall notify the Borrower and the
Banks that the circumstances causing such suspension no longer exist, and each Advance
comprising such Borrowing shall be a Base Rate Advance; and

     (v) if the Borrower shall fail to select the duration or continuation of any Interest
Period for any Eurodollar Rate Advances in accordance with the provisions contained in the
definition of “Interest Period” in Section 1.1 and paragraph (b) above, the Agent
shall forthwith so notify the Borrower and the Banks and such Advances shall be made
available to the Borrower on the date of such Borrowing as Base Rate Advances or, if an
existing Advance, Convert into Base Rate Advances.

     (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or
Continuation shall be irrevocable and binding on the Borrower. In the case of any Borrowing which
the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the
Borrower shall indemnify each Bank against any loss, out-of-pocket cost, or expense incurred by
such Bank as a result of any failure by the Borrower to fulfill on or before the date specified in
such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III
including, without limitation, any loss, cost, or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Bank to fund the Advance to be made by
such Bank as part of such Borrowing when such Advance, as a result of such failure, is not made on
such date.

     (e) Agent Reliance. Unless the Agent shall have received notice from a Bank before
the date of any Borrowing that such Bank shall not make available to the Agent such Bank’s Pro Rata
Share of such Borrowing, the Agent may assume that such Bank has made its Pro Rata Share of such
Borrowing available to the Agent on the date of such Borrowing in accordance with paragraph (a) of
this Section 2.3 and the Agent may, in reliance upon such assumption, make available to the
Borrower on such date a corresponding amount. If and to the extent that

- 21 -

 

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

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

     Section 2.4. Prepayment of Advances.

     (a) Optional. The Borrower may prepay Advances, after giving by 10:00 a.m. (Dallas,
Texas time) (i) in the case of Eurodollar Rate Advances, at least two Business Days’ or (ii) in
case of Base Rate Advances, same Business Day’s, irrevocable prior written notice to the Agent
stating the proposed date and aggregate principal amount of such prepayment. If any such notice is
given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably
in part in an aggregate principal amount equal to the amount specified in such notice;
provided, however, that each partial prepayment with respect to: (A) any Borrowing
comprised of Base Rate Advances shall be made in $100,000 multiples and in an aggregate principal
amount such that after giving effect thereto such Borrowing shall have a principal amount
outstanding of at least $500,000 and (B) any Borrowing comprised of Eurodollar Rate Advances shall
be made in $1,000,000 multiples and in an aggregate principal amount such that after giving effect
thereto such Borrowing shall have a principal amount outstanding of at least $2,000,000. Full
prepayments of any Borrowing are permitted without restriction of amounts.

     (b) Mandatory.

     (i) Borrowing Base Deficiency. Subject to Section 2.4(b)(ii), (iv), and
(v) below, if the aggregate outstanding amount of Advances plus the Letter of Credit
Exposure ever exceeds the Borrowing Base (such excess being referred to herein as the
“Borrowing Base Deficiency”), the Borrower shall, within ten days after receipt of
written notice of such condition from the Agent elect by written notice to the Agent to take
one or more of the following actions to remedy such Borrowing Base Deficiency:

     (A) prepay Advances and, if the Advances have been repaid in full, make
deposits into the Cash Collateral Account to provide cash collateral for the Letter
of Credit Exposure, such that the Borrowing Base Deficiency is cured within ten days
after the Borrower’s written election;

- 22 -

 

     (B) add additional Oil and Gas Properties acceptable to the Majority Banks to
the Borrowing Base (and take such actions as are requested by the Agent to cause
such additional Oil and Gas Properties to become subject to Mortgages, to the extent
necessary to cause the Mortgaged Property Value to equal or exceed 80% of the Oil
and Gas Property Value) such that the Borrowing Base Deficiency is cured within 30
days after the Borrower’s written election; or

     (C) pay the deficiency in monthly installments in amounts not greater than one
half of the deficiency in any one monthly payment or such lesser amounts
satisfactory to the Majority Banks for the prepayment of Advances and, if the
Advances have been repaid in full, make deposits into the Cash Collateral Account to
provide cash collateral for the Letter of Credit Exposure such that the Borrowing
Base Deficiency is eliminated in a period of 90 days or such longer period
satisfactory to the Majority Banks, but in no event to exceed six months.

     (ii) Reduction of Commitments. On the date of each reduction of the aggregate
Commitments pursuant to Section 2.1(b), the Borrower agrees to make a prepayment in
respect of the outstanding amount of the Advances and the Letter of Credit Exposure to the
extent, if any, that the aggregate unpaid principal amount of all Advances plus the
Letter of Credit Exposure exceeds the Commitments, as so reduced. Any amount paid under the
preceding sentence in respect of Letter of Credit Exposure shall be held as cash collateral
under Section 2.6(g).

     (iii) Asset Sales. If, after giving effect to the sale, transfer or other
disposition of any of the Borrower’s or any of its Subsidiaries’ Borrowing Base Assets, the
aggregate outstanding amount of Advances plus the Letter of Credit Exposure exceeds the
Borrowing Base, the Borrower shall repay the Advances, and then cash collateralize the
Letter of Credit Exposure, by an amount equal to the lesser of (A) such Borrowing Base
Deficiency and (B) 100% of the Net Cash Proceeds of such sale, transfer, or other
disposition, within three days after receipt of such proceeds.

     (iv) Property, Physical Damage and Other Insurance Proceeds. If any Credit
Party (or Agent as loss payee or assignee) receives any Property Proceeds arising from a
single event or related series of events, whether as one payment or a series of payments,
(A) during the existence of a Default or Event of Default, then the Borrower shall repay the
Advances, and then cash collateralize the Letter of Credit Exposure, by an amount equal to
100% of such Property Proceeds, upon receipt of such proceeds, and (B) during the existence
of a Borrowing Base Deficiency, then the Borrower shall repay the Advances, and then cash
collateralize the Letter of Credit Exposure, by an amount equal to the lesser of (1) such
Borrowing Base Deficiency and (2) 100% of such Property Proceeds, within three days after
receipt of such proceeds.

     (v) Illegality. If any Bank shall notify the Agent and the Borrower that the
introduction of or any change in or in the interpretation of any law or regulation makes it
unlawful, or that any central bank or other governmental authority asserts that it is
unlawful for such Bank or its Eurodollar Lending Office to perform its obligations under
this Agreement to maintain any Eurodollar Rate Advances of such Bank then outstanding

- 23 -

 

hereunder, (i) the Borrower shall, no later than 10:00 a.m. (Dallas, Texas time) (A) if
not prohibited by law, on the last day of the Interest Period for each outstanding
Eurodollar Rate Advance made by such Bank or (B) if required by such notice, on the second
Business Day following its receipt of such notice prepay all of the Eurodollar Rate Advances
made by such Bank then outstanding, (ii) such Bank shall simultaneously make a Base Rate
Advance to the Borrower on such date in an amount equal to the aggregate principal amount of
the Eurodollar Rate Advances prepaid to such Bank, and (iii) the right of the Borrower to
select Eurodollar Rate Advances from such Bank for any subsequent Borrowing shall be
suspended until such Bank gives notice referred to above shall notify the Agent that the
circumstances causing such suspension no longer exist.

     (c) No Additional Right; Ratable Prepayment; Interest and Breakage. The Borrower
shall have no right to prepay any principal amount of any Advance except as provided in this
Section 2.4, and all notices given pursuant to this Section 2.4 shall be
irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this
Section 2.4 shall be made in a manner such that all Advances comprising part of the same
Borrowing are paid in whole or ratably in part. Each prepayment pursuant to this
Section 2.4 shall be accompanied by accrued interest on the amount prepaid to the date of
such prepayment and amounts, if any, required to be paid pursuant to Section 2.11 as a
result of such prepayment being made on such date.

     Section 2.5. Repayment of Advances. The Borrower shall repay to the Agent for the
ratable benefit of the Banks the outstanding principal amount of each Advance on the Maturity Date.

     Section 2.6. Letters of Credit.

     (a) Commitment. From time to time from the date of this Agreement until the Maturity
Date, at the request of the Borrower, the Issuing Bank shall, on the terms and conditions
hereinafter set forth, issue, increase, or extend the expiration date of Letters of Credit for the
account of the Borrower on any Business Day;

     (i) provided that no Letter of Credit shall be issued, increased, or extended:

(A) unless such issuance, increase, extension or conversion would not cause
the Letter of Credit Exposure to exceed the lesser of (1) $300,000,000 or
(2) the lesser of (x) the aggregate Commitments less the aggregate
outstanding principal amount of all Advances or (y) the Borrowing Base
less the aggregate outstanding principal amount of all Advances;

(B) unless such Letter of Credit has an Expiration Date not later than the
earlier of (1) 12 months after the date of issuance thereof (or, if
extendable beyond such period, unless such Letter of Credit is cancelable
upon at least 30 days’ notice given by the Issuing Bank to the beneficiary
of such Letter of Credit) or (2) five days prior to the Maturity Date;

(C) unless such Letter of Credit Documents are in form and substance
acceptable to the Issuing Bank in its sole discretion;

- 24 -

 

(D) unless such Letter of Credit is a standby letter of credit not
supporting the repayment of indebtedness for borrowed money of any Person;
and

(E) unless the Borrower has delivered to the Issuing Bank a completed and
executed Letter of Credit Application; and

     (ii) provided further that the Issuing Bank shall not be under any
obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or
arbitrator shall by its terms purport to enjoin or restrain the Issuing Bank
from issuing such Letter of Credit, or any Legal Requirement applicable to
the Issuing Bank or any request or directive (whether or not having the
force of law) from any Governmental Authority with jurisdiction over the
Issuing Bank shall prohibit, or request that the Issuing Bank refrain from,
the issuance of letters of credit generally or such Letter of Credit in
particular or shall impose upon the Issuing Bank with respect to such Letter
of Credit any restriction, reserve or capital requirement (for which the
Issuing Bank is not otherwise compensated hereunder) not in effect on the
Effective Date, or shall impose upon the Issuing Bank any unreimbursed loss,
cost, or expense which was not applicable on the Effective Date and which
the Issuing Bank in good faith deems material to it;

(B) the issuance of such Letter of Credit would violate one or more policies
of the Issuing Bank; or

(C) a default of any Bank’s obligations to fund under Section 2.6(d)
exists or any Bank is at such time a Defaulting Bank hereunder, unless the
Issuing Bank has entered into satisfactory arrangements with the Borrower or
such Bank to eliminate the Issuing Bank’s risk with respect to such Bank.

As of the Effective Date, the Existing Letters of Credit shall be deemed “Letters of Credit”
hereunder and shall be subject to the terms and provisions set forth herein.

     (b) Participations. Upon the date of the issuance or increase of a Letter of Credit
or the conversion of an Existing Letter of Credit to a Letter of Credit, the Issuing Bank shall be
deemed to have sold to each other Bank and each other Bank shall have been deemed to have purchased
from the Issuing Bank a participation in the related Letter of Credit Obligations equal to such
Bank’s Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with
the terms of this Agreement. The Issuing Bank shall promptly notify each such participant Bank by
telex, telephone, or telecopy of each Letter of Credit issued, increased, or extended or converted
and the actual dollar amount of such Bank’s participation in such Letter of Credit.

-25-

 

     (c) Issuing. Each Letter of Credit shall be issued, increased, or extended pursuant
to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter
of Credit Application), given not later than 10:00 a.m. (Dallas, Texas time) on the fifth Business
Day before the date of the proposed issuance, increase, or extension of the Letter of Credit, and
the Agent shall give to each Bank prompt notice thereof by telex, telephone, or telecopy. Each
Letter of Credit Application shall be given by telecopier or telex, confirmed immediately in
writing, specifying the information required therein. After the Agent’s receipt of such Letter of
Credit Application and upon fulfillment of the applicable conditions set forth in Article III, the
Agent shall issue, increase, or extend such Letter of Credit for the account of the Borrower. Each
Letter of Credit Application shall be irrevocable and binding on the Borrower.

     (d) Reimbursement. The Borrower hereby agrees to pay on demand to the Issuing Bank an
amount equal to any amount paid by the Issuing Bank under any Letter of Credit. In the event the
Issuing Bank makes a payment pursuant to a request for draw presented under a Letter of Credit and
such payment is not promptly reimbursed by the Borrower upon demand, the Issuing Bank shall give
the Agent notice of the Borrower’s failure to make such reimbursement and the Agent shall promptly
notify each Bank of the amount necessary to reimburse the Issuing Bank. Upon such notice from the
Agent, each Bank shall promptly reimburse the Issuing Bank for such Bank’s Pro Rata Share of such
amount, and such reimbursement shall be deemed for all purposes of this Agreement to be an Advance
to the Borrower transferred at the Borrower’s request to the Issuing Bank. If such reimbursement
is not made by any Bank to the Issuing Bank on the same day on which the Agent notifies such Bank
to make reimbursement to the Issuing Bank hereunder, such Bank shall pay interest on its Pro Rata
Share thereof to the Issuing Bank at a rate per annum equal to the Federal Funds Rate. The
Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Agent and the
Banks to record and otherwise treat such reimbursements to the Issuing Bank as Base Rate Advances
under a Borrowing requested by the Borrower to reimburse the Issuing Bank which have been
transferred to the Issuing Bank at the Borrower’s request.

     (e) Obligations Unconditional. The obligations of the Borrower under this Agreement
in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances, including, without
limitation, the following circumstances:

     (i) any lack of validity or enforceability of any Letter of Credit Documents;

     (ii) any amendment or waiver of, or any consent to, departure from any Letter of Credit
Documents;

     (iii) the existence of any claim, set-off, defense, or other right which the Borrower
may have at any time against any beneficiary or transferee of such Letter of Credit (or any
Persons for whom any such beneficiary or any such transferee may be acting), the Issuing
Bank, or any other person or entity, whether in connection with this Agreement, the
transactions contemplated in this Agreement or in any Letter of Credit Documents, or any
unrelated transaction;

-26-

 

     (iv) any statement or any 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 to the extent the Issuing Bank would not be liable
therefor pursuant to the following paragraph (f); or

     (v) payment by the Issuing Bank under such Letter of Credit against presentation of a
draft or certificate which does not comply with the terms of such Letter of Credit;

provided, however, that nothing contained in this paragraph (e) shall be deemed to
constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit or the
Borrower’s rights under Section 2.6(f) below.

     (f) Liability of Issuing Bank. The Borrower assumes all risks of the acts or
omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such
Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or
responsible for:

     (i) the use which may be made of any Letter of Credit or any acts or omissions of any
beneficiary or transferee in connection therewith;

     (ii) the validity, sufficiency, or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects invalid,
insufficient, fraudulent, or forged;

     (iii) payment by the Issuing Bank against presentation of documents which do not comply
with the terms of a Letter of Credit, including failure of any documents to bear any
reference or adequate reference to the relevant Letter of Credit; or

     (iv) any other circumstances whatsoever in making or failing to make payment under any
Letter of Credit (INCLUDING THE ISSUING BANK’S OWN NEGLIGENCE),

except that the Borrower shall have a claim against the Issuing Bank, and the Issuing Bank
shall be liable to the Borrower, to the extent of any direct, as opposed to consequential, damages
suffered by the Borrower which the Borrower proves were caused by (A) the Issuing Bank’s willful
misconduct or gross negligence in determining whether documents presented under a Letter of Credit
comply with the terms of such Letter of Credit or (B) the Issuing Bank’s willful failure to make
lawful payment under any Letter of Credit after the presentation to it of a draft and certificate
strictly complying with the terms and conditions of such Letter of Credit. 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.

     (g) Cash Collateral Account.

     (i) If the Borrower is required to deposit funds in the Cash Collateral Account
pursuant to Sections 2.4(b) or (c), 7.2(b), or 7.3(b), then
the Borrower and the Agent shall

-27-

 

establish the Cash Collateral Account and the Borrower shall execute any documents and
agreements, including the Agent’s standard form assignment of deposit accounts, that the
Agent requests in connection therewith to establish the Cash Collateral Account and grant
the Agent a first priority security interest in such account and the funds therein. The
Borrower hereby pledges to the Agent and grants the Agent a security interest in the Cash
Collateral Account, whenever established, all funds held in the Cash Collateral Account from
time to time, and all proceeds thereof as security for the payment of the Obligations.

     (ii) So long as no Event of Default exists, (A) the Agent may apply the funds held in
the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations,
and (B) the Agent shall release to the Borrower at the Borrower’s written request any funds
held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any
(immediately prior to the release of any such funds), of the total amount of funds held in
the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any
Event of Default, the Agent may apply any funds held in the Cash Collateral Account to the
Obligations in any order determined by the Agent, regardless of any Letter of Credit
Exposure which may remain outstanding. The Agent may in its sole discretion at any time
release to the Borrower any funds held in the Cash Collateral Account.

     (iii) The Agent shall exercise reasonable care in the custody and preservation of any
funds held in the Cash Collateral Account and shall be deemed to have exercised such care if
such funds are accorded treatment substantially equivalent to that which the Agent accords
its own property, it being understood that the Agent shall not have any responsibility for
taking any necessary steps to preserve rights against any parties with respect to any such
funds.

     Section 2.7. Fees.

     (a) Commitment Fees.

     (i) The Borrower agrees to pay to the Agent for the account of each Bank a commitment
fee per annum equal to the Applicable Margin for commitment fees in effect from time to time
on the average daily amount by which such Bank’s Pro Rata Share of the Borrowing Base
exceeds the sum of such Bank’s outstanding Advances and such Bank’s Pro Rata Share of the
Letter of Credit Exposure, from the Effective Date until the Maturity Date.

     (ii) The commitment fees shall be due and payable quarterly in arrears on the last day
of each March, June, September, and December during the term of this Agreement and on the
Maturity Date.

     (b) Agent and Arranger Fees. The Borrower agrees to pay to the Agent and the Arranger
for their own accounts the fees described in the letter dated April 29, 2008 from the Agent and the
Arranger to the Borrower.

     (c) Bank Fees. The Borrower agrees to pay to the Agent for the ratable benefit of the
Banks on the Effective Date, the fees agreed to between the Borrower and the Banks.

-28-

 

     (d) Letter of Credit Fees.

     (i) The Borrower agrees to pay (A) to the Agent for the pro rata benefit of the Banks a
per annum fee for each Letter of Credit issued hereunder equal to the Applicable Margin for
Eurodollar Advances on the face amount of such Letter of Credit, but with a minimum annual
fee of $1,000 on each Letter of Credit (collectively, the “Letter of Credit Fees”),
and (B) to the Agent for the benefit of the Issuing Bank a fronting fee for each Letter of
Credit equal to 0.125% per annum of the face amount of such Letter of Credit, but with a
minimum annual fee of $1,000 on each Letter of Credit. Each such fee with respect to a
Letter of Credit shall be payable quarterly in arrears for the period such Letter of Credit
is outstanding, and on the Maturity Date.

     (ii) The Borrower agrees to pay 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 customary fees and standard costs and charges are due and payable on demand and are
nonrefundable.

     Section 2.8. Interest. The Borrower shall pay interest on the unpaid principal amount
of each Advance made by each Bank from the date of such Advance until such principal amount shall
be paid in full, at the following rates per annum:

     (a) Base Rate Advances. If such Advance is a Base Rate Advance, a rate per annum
equal at all times to the Adjusted Base Rate in effect from time to time plus the
Applicable Margin in effect from time to time, payable in arrears on the last day of March, June,
September, and December and on the date such Base Rate Advance shall be paid in full,
provided that any amount of principal which is not paid when due (whether at stated
maturity, by acceleration, or otherwise) shall bear interest from the date on which such amount is
due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to
the Adjusted Base Rate in effect from time to time plus the Applicable Margin plus
2.00% per annum.

     (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate
per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for
such Interest Period plus the Applicable Margin in effect from time to time, payable on the
last day of such Interest Period, and, in the case of Interest Periods that are longer than three
months, every three months and on the last day of such Interest Period, provided that any
amount of principal which is not paid when due (whether at stated maturity, by acceleration, or
otherwise) shall bear interest from the date on which such amount is due until such amount is paid
in full, payable on demand, at a rate per annum equal to (i) until the end of the relevant Interest
Period, the Eurodollar Rate in effect from time to time plus the Applicable Margin plus
2.00% per annum and (ii) thereafter, the Adjusted Base Rate in effect from time to time
plus the Applicable Margin plus 2.00% per annum.

     (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each
Bank, so long as any such Bank shall be required under regulations of the Federal Reserve Board to
maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency
Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance

-29-

 

of such Bank, from the effective date of such Advance until such principal amount is paid in
full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i)
the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by
dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve
Percentage of such Bank for such Interest Period, payable on each date on which interest is payable
on such Advance. Such additional interest payable to any Bank shall be determined by such Bank and
notified to the Borrower through the Agent (such notice to include the calculation of such
additional interest, which calculation shall be conclusive in the absence of manifest error).

     (d) Usury.

     (i) If, with respect to any Bank, the effective rate of interest contracted for under
the Credit Documents, including the stated rates of interest and fees contracted for
hereunder and any other amounts contracted for under the Credit Documents which are deemed
to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount
of the loans made by such Bank hereunder shall bear interest at a rate which would make the
effective rate of interest for such Bank under the Credit Documents equal the Maximum Rate
until the difference between the amounts which would have been due at the stated rates and
the amounts which were due at the Maximum Rate (the “Lost Interest”) has been
recaptured by such Bank.

     (ii) If, when the loans made hereunder are repaid in full, the Lost Interest has not
been fully recaptured by such Bank pursuant to the preceding paragraph, then, to the extent
permitted by law, for the loans made hereunder by such Bank the interest rates charged under
Section 2.8 hereunder shall be retroactively increased such that the effective rate
of interest under the Credit Documents was at the Maximum Rate since the effectiveness of
this Agreement to the extent necessary to recapture the Lost Interest not recaptured
pursuant to the preceding sentence and, to the extent allowed by law, the Borrower shall pay
to such Bank the amount of the Lost Interest remaining to be recaptured by such Bank.

     (iii) In calculating all sums paid or agreed to be paid to any Bank by the Borrower for
the use, forbearance, or detention of money under the Credit Documents, such amounts shall,
to the extent permitted by applicable law, be amortized, prorated, allocated, and spread in
equal parts throughout the term of the Credit Documents.

     (iv) NOTWITHSTANDING the foregoing or any other term in this Agreement and the Credit
Documents to the contrary, it is the intention of each Bank and the Borrower to conform
strictly to any applicable usury laws. Accordingly, if any Bank contracts for, charges, or
receives any consideration which constitutes interest in excess of the Maximum Rate, then
(A) the provisions of this Section 2.8, together with the second sentence of
Section 9.13 shall control, and (B) any such excess shall be canceled automatically
and, if previously paid, shall at such Bank’s option be applied to the outstanding amount of
the loans made hereunder by such Bank or be refunded to the Borrower. For purposes of
Chapter 303 of the Texas Finance Code, as amended, to the extent applicable, the Borrower
agrees that the Maximum Rate shall be the “indicated

-30-

 

(weekly) rate ceiling” as defined in said Chapter, provided that such Bank may
also rely, to the extent permitted by applicable laws, on alternative maximum rates of
interest under other laws applicable to such Bank, if greater.

     Section 2.9. Payments and Computations.

     (a) Payment Procedures. The Borrower shall make each payment under this Agreement and
under the Notes not later than 10:00 a.m. (Dallas, Texas time) on the day when due in Dollars to
the Agent at 901 Main Street, 14th Floor, Dallas, Texas 75202 (or such other location as the Agent
shall designate in writing to the Borrower), in same day funds. The Agent shall promptly
thereafter cause to be distributed like funds relating to the payment of principal, interest or
fees ratably (other than amounts payable solely to the Agent, the Issuing Bank, or a specific Bank
pursuant to Section 2.7(b), 2.8(c), 2.11, 2.12, 2.13,
8.7, or 9.7, but after taking into account payments effected pursuant to
Section 9.4) to the Banks for the account of their respective Applicable Lending Offices,
and like funds relating to the payment of any other amount payable to any Bank or the Issuing Bank
to such Bank for the account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement.

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

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

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

     Section 2.10. Sharing of Payments, Etc. If any Bank shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of
the Advances or Letter of Credit Obligations made by it in excess of its Pro Rata Share of payments
on account of the Advances or Letter of Credit Obligations obtained by all the Banks,

-31-

 

such Bank shall notify the Agent and forthwith purchase from the other Banks such
participations in the Advances made by them or Letter of Credit Obligations held by them as shall
be necessary to cause such purchasing Bank to share the excess payment ratably with each of them;
provided, however, that if all or any portion of such excess payment is thereafter
recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and such Bank
shall repay to the purchasing Bank the purchase price to the extent of such Bank’s ratable share
(according to the proportion of (a) the amount of the participation sold by such Bank to the
purchasing Bank as a result of such excess payment to (b) the total amount of such excess payment)
of such recovery, together with an amount equal to such Bank’s ratable share (according to the
proportion of (a) the amount of such Bank’s required repayment to the purchasing Bank to (b) the
total amount of all such required repayments to the purchasing Bank) of any interest or other
amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The
Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.10 may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of set-off) with respect to such participation as fully as if such
Bank were the direct creditor of the Borrower in the amount of such participation.

     Section 2.11. Breakage Costs. If (a) any payment of principal of any Eurodollar Rate
Advance is made other than on the last day of the Interest Period for such Advance, whether as a
result of any payment pursuant to Section 2.4, the acceleration of the maturity of the
Notes pursuant to Article VII, or otherwise, or (b) the Borrower fails to make a principal
or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and
payable, the Borrower shall, within 10 days of any written demand sent by any Bank to the Borrower
through the Agent, pay to the Agent for the account of such Bank any amounts required to compensate
such Bank for any additional losses, out-of-pocket costs or expenses which it may reasonably incur
as a result of such payment or nonpayment, including, without limitation, any loss (including loss
of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by any Bank to fund or maintain such Advance. If, following the
Effective Date for a period of the earlier of 90 days or the date on which Banc of America
Securities LLC declares the syndication to be completed, any such breakage costs, charges or fees
are incurred with respect to Eurodollar Rate Advances on account of the syndication of the credit
facility evidenced by this Agreement, the Borrower shall immediately reimburse the Agent for any
such costs, charges or fees. Such right of reimbursement shall be in addition to and not in
limitation of the protections set forth above and elsewhere in this Agreement.

     Section 2.12. Increased Costs.

     (a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change
(other than any change by way of imposition or increase of reserve requirements included in the
Eurodollar Rate Reserve Percentage) in, or in the interpretation of, any law or regulation after
the date hereof or (ii) the compliance with any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law) made after the date hereof, there
shall be any increase in the cost to any Bank of agreeing to make or making, funding, or
maintaining Eurodollar Rate Advances, then the Borrower shall from time to time, upon demand by
such Bank (with a copy of such demand to the Agent), immediately pay to the Agent for the account
of such Bank additional amounts sufficient to compensate such Bank for such increased

-32-

 

cost. A certificate as to the amount of such increased cost and detailing the calculation of
such cost submitted to the Borrower and the Agent by such Bank shall be conclusive and binding for
all purposes, absent manifest error.

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

     (c) Letters of Credit. If any change in any law or regulation or in the
interpretation thereof after the date hereof by any court or administrative or Governmental
Authority charged with the administration thereof shall either (i) impose, modify, or deem
applicable any reserve, special deposit, or similar requirement against letters of credit issued
by, or assets held by, or deposits in or for the account of, the Issuing Bank or (ii) impose on the
Issuing Bank any other condition regarding the provisions of this Agreement relating to the Letters
of Credit or any Letter of Credit Obligations, and the result of any event referred to in the
preceding clause (i) or (ii) shall be to increase the cost to the Issuing Bank of issuing or
maintaining any Letter of Credit (which increase in cost shall be determined by the Issuing Bank’s
reasonable allocation of the aggregate of such cost increases resulting from such event), then,
upon demand by the Issuing Bank, the Borrower shall pay to the Issuing Bank, from time to time as
specified by the Issuing Bank, additional amounts which shall be sufficient to compensate the
Issuing Bank for such increased cost. A certificate as to such increased cost incurred by the
Issuing Bank, as a result of any event mentioned in clause (i) or (ii) above, and detailing the
calculation of such increased costs submitted by the Issuing Bank to the Borrower, shall be
conclusive and binding for all purposes, absent manifest error.

     Section 2.13. Taxes.

     (a) No Deduction for Certain Taxes. Any and all payments by the Borrower shall be
made, in accordance with Section 2.9, free and clear of and without deduction for any and
all present or future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank, the Issuing Bank, and the
Agent, (i)

-33-

 

taxes imposed on or measured by its income, and franchise taxes imposed on it, by the United
States of America or the jurisdiction (or any political subdivision thereof) under the laws of
which such Bank, the Issuing Bank, or the Agent (as the case may be) is organized or in which its
principal office is located or, in the case of any Bank or the Issuing Bank, in which its
applicable lending office is located, (ii) any branch profits taxes imposed by the United States of
America or any similar tax imposed by any other jurisdiction in which the Borrower is located and
(iii) in the case of a Foreign Bank (as defined in subparagraph (d), hereof), any withholding tax
that is imposed on amounts payable to such Foreign Bank at the time such Foreign Bank becomes a
party to this Agreement or other Credit Document (or designates a new lending office) (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct
any Taxes from or in respect of any sum payable to any Bank, the Issuing Bank, or the Agent, (i)
the sum payable shall be increased as may be necessary so that, after making all required
deductions (including deductions applicable to additional sums payable under this Section
2.13), such Bank, the Issuing Bank, or the Agent (as the case may be) receives an amount equal
to the sum it would have received had no such deductions been made; provided, however, that
if the Borrower’s obligation to deduct or withhold Taxes is caused solely by such Bank’s, the
Issuing Bank’s, or the Agent’s failure to provide the forms described in paragraph (d) of this
Section 2.13 and such Bank, the Issuing Bank, or the Agent could have provided such forms,
no such increase shall be required; (ii) the Borrower shall make such deductions; and (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority or other authority
in accordance with applicable law.

     (b) Other Taxes. In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar levies which arise
from any payment made or from the execution, delivery or registration of, or otherwise with respect
to, this Agreement, the Notes, or the other Credit Documents (hereinafter referred to as “Other
Taxes”).

     (c) Indemnification. THE BORROWER INDEMNIFIES EACH BANK, THE ISSUING BANK, AND THE
AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR
OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.13) PAID BY
SUCH BANK, THE ISSUING BANK, OR THE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING
INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR
OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED. EACH PAYMENT REQUIRED TO BE MADE BY THE BORROWER
IN RESPECT OF THIS INDEMNIFICATION SHALL BE MADE TO THE AGENT FOR THE BENEFIT OF ANY PARTY CLAIMING
SUCH INDEMNIFICATION WITHIN 30 DAYS FROM THE DATE THE BORROWER RECEIVES WRITTEN DEMAND THEREFOR
FROM THE AGENT ON BEHALF OF ITSELF AS AGENT, THE ISSUING BANK, OR ANY SUCH BANK. NOTWITHSTANDING
ANYTHING HEREIN TO THE CONTRARY, NO BANK, THE ISSUING BANK OR THE AGENT SHALL BE INDEMNIFIED FOR
ANY TAXES HEREUNDER UNLESS SUCH BANK, ISSUING BANK OR AGENT SHALL MAKE WRITTEN DEMAND ON THE
BORROWER FOR REIMBURSEMENT HEREUNDER NO LATER THAN 120 DAYS AFTER THE EARLIER OF (I) THE DATE ON
WHICH SUCH

-34-

 

BANK, ISSUING BANK OR AGENT MAKES PAYMENT OF SUCH TAXES AND (II) THE DATE ON WHICH THE RELEVANT
GOVERNMENT AUTHORITY MAKES WRITTEN DEMAND UPON SUCH BANK, ISSUING BANK OR AGENT FOR PAYMENT OF SUCH
TAXES. IF ANY BANK, THE AGENT, OR THE ISSUING BANK RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID
BY THE BORROWER UNDER THIS PARAGRAPH (C), SUCH BANK, THE AGENT, OR THE ISSUING BANK, AS THE CASE
MAY BE, SHALL PROMPTLY PAY TO THE BORROWER THE BORROWER’S SHARE OF SUCH REFUND.

     (d) Withholding Exemption. Each Bank and the Issuing Bank, if requested by the
Borrower or the Agent, shall deliver such documentation (including Form W-9) prescribed by
applicable law or reasonably requested by the Borrower or the Agent as will enable the Borrower or
the Agent to determine whether or not such Bank or Issuing Bank is subject to backup withholding or
information reporting requirements. In addition, each Bank and Issuing Bank that is not
incorporated under the laws of the United States of America or a state thereof (a “Foreign
Bank”) agrees that it will deliver to the Borrower and the Agent on the date of this Agreement
or upon the effectiveness of any Assignment and Acceptance and from time to time thereafter if
requested in writing by the Borrower, to the extent applicable, (i) Internal Revenue Service Form
W-8ECI, W-8BEN, W-8EXP, or W-8IMY as appropriate, or any successor form prescribed by the Internal
Revenue Service, certifying that such Bank is entitled to benefits under an income tax treaty to
which the United States is a party which exempts such Bank from withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement or other Credit
Document is effectively connected with the conduct of a trade or business in the United States,
(ii) in the case of a Foreign Bank claiming the benefits of the exemption for portfolio interest
under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Bank is not (A)
a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of
the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign
corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of
Internal Revenue Service Form W-8BEN, and (iii) any other form prescribed by applicable law as a
basis for claiming an exemption from tax on payments pursuant to this Agreement or any of the other
Credit Documents. If an event (including without limitation any change in treaty, law or
regulation) has occurred prior to the date on which any delivery required by the preceding sentence
would otherwise be required which renders all such forms inapplicable or which would prevent any
Bank from duly completing and delivering any such letter or form with respect to it and such Bank
advises the Borrower and the Agent that it is not capable of receiving payments without any
deduction or withholding of United States federal income tax, and, in the case of a Form W-9,
establishing an exemption from United States backup withholding tax, such Bank shall not be
required to deliver such letter or forms.

-38-

ARTICLE IV

REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants as follows:

     Section 4.1. Corporate Existence; Subsidiaries. The Borrower is a corporation duly
organized, validly existing, and in good standing under the laws of Delaware and in good standing
and qualified to do business in each jurisdiction where its ownership or lease of property or
conduct of its business requires such qualification and where a failure to be qualified could
reasonably be expected to cause a Material Adverse Change. Each Guarantor is a corporation,
limited liability company, or limited partnership duly organized, validly existing, and in good
standing under the laws of its jurisdiction of formation and in good standing and qualified to do
business in each jurisdiction where its ownership or lease of property or conduct of its business
requires such qualification and where a failure to be qualified could reasonably be expected to
cause a Material Adverse Change. Each Material Subsidiary of the Borrower (after giving effect to
the Mergers) has executed a Guaranty and otherwise complied with the requirements of Section
5.8. Schedule 4.1 lists each Material Subsidiary of the Borrower (after giving effect
to the Mergers), its jurisdiction and type of organization, and the owners of the equity interests
in such Material Subsidiary.

     Section 4.2. Corporate Power; Authorization; No Violation.

     (a) The execution, delivery, and performance by the Borrower of this Agreement, the Notes, and
the other Credit Documents to which it is a party and by the Guarantors of the Guaranties and the
consummation of the transactions contemplated hereby and thereby (including the Mergers) (i) are
within the Borrower’s and the Guarantors’ corporate, limited liability, or limited partnership
powers, (ii) have been duly authorized by all necessary corporate, limited liability, or limited
partnership action, (iii) do not contravene (A) the Borrower’s or any Guarantor’s certificate or
articles, as the case may be, of incorporation or by-laws or other formation documents or (B) any
law or any material contractual restriction binding on or affecting the Borrower or any Guarantor,
and (iv) will not result in or require (A) the creation or imposition of any Lien prohibited by
this Agreement or (B) any preferential right, right of first refusal, consent right, or similar
right of a counterparty under any material contract.

-39-

 

     (b) At the time of each Borrowing, such Borrowing and the use of the proceeds of such
Borrowing (i) will be within the Borrower’s corporate powers, (ii) will have been duly authorized
by all necessary corporate action on the part of the Borrower, (iii) will not contravene (A) the
Borrower’s certificate of incorporation or by-laws or (B) any law or any material contractual
restriction binding on or affecting the Borrower, and (iv) will not result in or require the
creation or imposition of any Lien prohibited by this Agreement.

     Section 4.3. Authorization and Approvals. No authorization or approval or other
action by, and no notice to or filing with, any Governmental Authority or third party is required
for the due execution, delivery, and performance by the Borrower of this Agreement, the Notes, or
the other Credit Documents to which the Borrower is a party or by each Guarantor of its Guaranty or
the consummation of the transactions contemplated thereby, except for (i) those that have already
been obtained or made, (ii) routine consents, authorizations, filings and notices required to be
made in the ordinary course of business, (iii) the filing of UCC-1 or UCC-3 financing statements in
the appropriate filing offices, and (iv) filings required pursuant to Section 5.8 in
connection with new Material Subsidiaries or Section 5.11 and Section 5.12 in
connection with the mortgaging of additional Oil and Gas Properties). At the time of each
Borrowing, no authorization or approval or other action by, and no notice to or filing with, any
Governmental Authority or third party will be required for such Borrowing or the use of the
proceeds of such Borrowing.

     Section 4.4. Enforceable Obligations. This Agreement, the Notes, and the other Credit
Documents to which the Borrower is a party have been duly executed and delivered by the Borrower
and the Guaranties and the other Credit Documents to which any Guarantor is a party have been duly
executed and delivered by such Guarantor. Each Credit Document is the legal, valid, and binding
obligation of the Borrower and each Guarantor which is a party to it enforceable against the
Borrower and each such Guarantor in accordance with its terms, except as such enforceability may be
limited by any applicable bankruptcy, insolvency, reorganization, moratorium, or similar law
affecting creditors’ rights generally and by general principles of equity.

     Section 4.5. Financial Statements. The Financial Statements, copies of which have
been furnished to each Bank, fairly present in all material respects the consolidated financial
condition of the Borrower and its Subsidiaries, as at such date and the consolidated results of the
operations of the Borrower and its Subsidiaries, for the fiscal year ended on such date, and such
consolidated balance sheets and consolidated statements of operations, cash flow, and stockholders’
equity were prepared in accordance with GAAP (or in compliance with the regulations promulgated by
the United States Securities and Exchange Commission). Since the date of the Financial Statements,
no Material Adverse Change has occurred.

     Section 4.6. True and Complete Disclosure.

     (a) All factual information (excluding estimates, projections, and pro forma financial
information) heretofore or contemporaneously furnished by or on behalf of the Borrower or any of
its Subsidiaries (prior to giving effect to the Bois d’Arc Merger) in writing to any Bank or the
Agent for purposes of or in connection with this Agreement, any other Credit Document or any
transaction contemplated hereby or thereby (but limited to those delivered by the Borrower or its

-40-

 

Subsidiaries (prior to giving effect to the Bois d’Arc Merger) to a Bank or the Agent in
connection with such agreements and transactions in anticipation of or in connection with this
amendment and restatement and the Mergers) is (taken as a whole) true and correct in all material
respects on the date as of which such information is dated or certified and does not contain any
untrue statement of a material fact or omit to state any material fact necessary to make the
statements contained therein not misleading as of the date of this Agreement, in light of the
circumstances under which they were made. All such projections, estimates, and pro forma financial
information heretofore or contemporaneously furnished by the Borrower or any of its Subsidiaries
(prior to giving effect to the Bois d’Arc Merger) were prepared in good faith on the basis of
assumptions, data, information, tests, or conditions believed to be reasonable at the time such
projections, estimates, and pro forma financial information were furnished.

     (b) All factual information (excluding estimates, projections, and pro forma financial
information) furnished by or on behalf of the Borrower or any of its Subsidiaries in writing to any
Bank or the Agent after the Effective Date for purposes of or in connection with this Agreement,
any other Credit Document or any transaction contemplated hereby or thereby is (taken as a whole)
true and correct in all material respects on the date as of which such information is dated or
certified and does not contain any untrue statement of a material fact or omit to state any
material fact necessary to make the statements contained therein not misleading, in light of the
circumstances under which they were made. All such projections, estimates, and pro forma financial
information furnished by the Borrower or any of its Subsidiaries after the Effective Date were
prepared in good faith on the basis of assumptions, data, information, tests, or conditions
believed to be reasonable at the time such projections, estimates, and pro forma financial
information were furnished.

     Section 4.7. Litigation. Set forth on Schedule 4.7 is an accurate description
of all of the Borrower’s and its Subsidiaries’ pending litigation existing on the date of this
Agreement which could reasonably be expected to cause a Material Adverse Change. There is no
pending or, to the best knowledge of the Borrower, threatened action, proceeding, or investigation
affecting the Borrower or any of its Subsidiaries before any court, Governmental Authority or
arbitrator, which (a) could reasonably be expected to cause a Material Adverse Change, except as
set forth on Schedule 4.7, or (b) purports to affect the legality, validity, binding
effect, or enforceability of this Agreement, any Note, or any other Credit Document.

     Section 4.8. Use of Proceeds. All Advances and Letters of Credit shall be used (a) to
partially finance the cash portion of the purchase price for the Bois d’Arc Merger, (b) to pay off
Debt outstanding under the Target’s senior credit facility and replace letters of credit
outstanding under such facility with, or deem them to be, Letters of Credit, (c) to pay costs and
expenses related to the Mergers and the credit facility evidenced by this Agreement, and (d) for
working capital, capital expenditures, and general corporate purposes of the Borrower and its
Subsidiaries (including without limitation to finance the acquisition of Oil and Gas Properties).
The Borrower is not engaged in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulation U). No proceeds of any Advance will be
used to purchase or carry any margin stock in violation of Regulation U or X.

-41-

 

     Section 4.9. Investment Company Act. Neither the Borrower nor any of its Subsidiaries
is an “investment company” or a company “controlled” by an “investment company” within the meaning
of the Investment Company Act of 1940, as amended.

     Section 4.10. Taxes. Proper and accurate (in all material respects) federal, state,
local, and foreign tax returns, reports and statements required to be filed (after giving effect to
any extension granted in the time of filing) by or on behalf of the Borrower, its Subsidiaries, or
any member of the Controlled Group (hereafter collectively called the “Tax Group”) have
been duly filed on a timely basis or appropriate extensions have been obtained with appropriate
governmental agencies in all jurisdictions in which such returns, reports, and statements are
required to be filed, except where the failure to so file would not be reasonably expected to cause
a Material Adverse Change; and all taxes (which are material in amount) and other impositions due
and payable have been timely paid prior to the date on which any fine, penalty, interest, late
charge, or loss may be added thereto for non-payment thereof, except where contested in good faith
by appropriate proceedings. The reserves for accrued taxes reflected in the financial statements
delivered to the Banks under this Agreement are adequate in the aggregate for the payment of all
unpaid taxes, whether or not disputed, for the period ended as of the date thereof and for any
period prior thereto, and for which the Tax Group may be liable in its own right, as withholding
agent or as a transferee of the assets of, or successor to, any Person, except for such taxes or
reserves therefor, the failure to pay or provide for which does not and could not cause a Material
Adverse Change, and except that no reserves are maintained for the Louisiana franchise taxes that
are the subject of the litigation described in paragraph 1 of Schedule 4.7. Timely payment
of all material sales and use taxes required by applicable law has been made by the Borrower and
all other members of the Tax Group.

     Section 4.11. Pension Plans. All Plans are in compliance in all material respects
with all applicable provisions of ERISA. No Termination Event has occurred with respect to any
Plan, and each Plan has complied with and been administered in all material respects with
applicable provisions of ERISA and the Code. No “accumulated funding deficiency” (as defined in
Section 302 of ERISA) has occurred and there has been no excise tax imposed under Section 4971 of
the Code. To the knowledge of the Borrower, no Reportable Event has occurred with respect to any
Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all
material respects with applicable provisions of ERISA and the Code. The present value of all
benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of
the last annual valuation date applicable thereto, exceed the value of the assets of such Plan
allocable to such vested benefits. Neither the Borrower nor any member of the Controlled Group has
had a complete or partial withdrawal from any Multiemployer Plan for which there is any withdrawal
liability. As of the most recent valuation date applicable thereto, neither the Borrower nor any
member of the Controlled Group would become subject to any liability under ERISA if the Borrower or
any member of the Controlled Group has received notice that any Multiemployer Plan is insolvent or
in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual
circumstances, the Borrower has no reason to believe that the annual cost during the term of this
Agreement to the Borrower or any member of the Controlled Group for post-retirement benefits to be
provided to the current and former employees of the Borrower or any member of the Controlled Group
under Plans that are welfare benefit plans (as defined in Section 3(a) of ERISA) could, in the
aggregate, reasonably be expected to cause a Material Adverse Change.

-42-

 

     Section 4.12. Condition of Property; Casualties. The material Properties used or to
be used in the continuing operations of the Borrower and each of its Subsidiaries are in all
material respects in good repair, working order and condition. Since the date of the Financial
Statements, neither the business nor the material Properties of the Borrower and each of its
Subsidiaries, taken as a whole, has experienced a Material Adverse Change been materially and
adversely affected as a result of any fire, explosion, earthquake, flood, drought, windstorm,
accident, strike or other labor disturbance, embargo, requisition or taking of property or
cancellation of contracts, permits, or concessions by a Governmental Authority, riot, activities of
armed forces, or acts of God or of any public enemy.

     Section 4.13. No Burdensome Restrictions; No Defaults. Neither the Borrower nor any
of its Subsidiaries is a party to any indenture, loan, or credit agreement or any lease or other
agreement or instrument or subject to any charter or corporate restriction or provision of
applicable law or governmental regulation which could reasonably be expected to cause a Material
Adverse Change. The Borrower and the Guarantors are not in default under or with respect to any
contract, agreement, lease, or other instrument to which the Borrower or any Guarantor is a party
and which could reasonably be expected to cause a Material Adverse Change. Neither the Borrower
nor any Guarantor has received any notice of default under any material contract, agreement, lease,
or other instrument to which the Borrower or such Guarantor is a party. No Default has occurred
and is continuing.

     Section 4.14. Environmental Condition.

its Subsidiaries (i) have obtained all Environmental Permits material to the ownership and
operation of their respective Properties and the conduct of their respective businesses; (ii) have

Environmental Permits and with all other applicable Environmental Laws; (iii) have not received

present or, to the Borrower’s actual knowledge, previously owned or operated Property of the
Borrower or of any of its present or former Subsidiaries, wherever located, (i) has been placed on
or proposed to be placed on the National Priorities List, the Comprehensive Environmental Response
Compensation Liability Information System list, or their state or local analogs, or have been
otherwise investigated, designated, listed, or identified as a potential site for any material

any Environmental Laws; (ii) is subject to a Lien, arising under or in connection with any
Environmental Laws, that attaches to any revenues or to any Property owned or operated by the
Borrower or any of its Subsidiaries, wherever located, which could reasonably be expected to cause
a Material Adverse Change; or (iii) has been the site of any Release of Hazardous Substances or
Hazardous Wastes from present or past operations which has caused at the site or at any third-party
site any condition that has resulted in or could reasonably be expected to result in the imposition
of any Response, notice, or investigation obligations on the Borrower or any of

-43-

 

its Subsidiaries under applicable Environmental Law that would cause a Material Adverse
Change.

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

     Section 4.15. Permits, Licenses, Etc.; Compliance with Legal Requirements. Except for
Environmental Permits, which are addressed in Section 4.14(a), the Borrower and its
Subsidiaries possess (a) all permits and licenses which are material to the conduct of its business
and (b) except where the failure to possess the same could not reasonably be expected to result in
a Material Adverse Change, all patents, patent rights or patent licenses, trademarks, trademark
rights, trade names rights and copyrights necessary for the conduct of its business. The Borrower
and its Subsidiaries manage and operate their business in accordance with all applicable Legal
Requirements and good industry practices, except where the failure to do so could not reasonably be
expected to result in a Material Adverse Change.

     Section 4.16. Gas Contracts. Neither the Borrower nor any of its Subsidiaries, as of
the date hereof, (a) is obligated in any material respect by virtue of any prepayment made under
any contract containing a “take-or-pay” or “prepayment” provision or under any similar agreement to
deliver hydrocarbons produced from or allocated to any of the Borrower’s consolidated Oil and Gas
Properties at some future date without receiving full payment therefor at the time of delivery, or
(b) has produced gas, in any material amount, subject to, and none of the Borrower’s consolidated
Oil and Gas Properties is subject to, balancing rights of third parties or subject to balancing
duties under governmental requirements, except as to such matters for which the Borrower or its
relevant Subsidiary has established monetary reserves adequate in amount in accordance with GAAP to
satisfy such obligations.

Material Adverse Change.

     (d) No Credit Party is a party to any agreement or arrangement (other than this Agreement, the
Security Documents, and the documents evidencing Debt referred to in Section 6.2(c)), or

ARTICLE V

AFFIRMATIVE COVENANTS

-45-

 

     So long as any Note or any amount under any Credit Document shall remain unpaid, any Letter of

agrees, unless the Majority Banks shall otherwise consent in writing, to comply with the following
covenants.

     Section 5.1. Compliance with Laws, Etc. The Borrower shall comply, and cause each of
its Subsidiaries to comply, with all Legal Requirements except where the failure to do so could not
reasonably be expected to result in a Material Adverse Change. Without limiting the generality and

comply with all Environmental Laws and all laws, regulations, or directives with respect to equal
employment opportunity and employee safety in all jurisdictions in which the Borrower, or any of
its Subsidiaries do business, except where the failure to do so could not reasonably be expected to
result in a Material Adverse Change; provided, however, that this Section 5.1 shall
not prevent the Borrower, or any of its Subsidiaries from, in good faith and with reasonable
diligence, contesting the validity or application of any such laws or regulations by appropriate
legal proceedings.

     Section 5.2. Maintenance of Insurance.

     (a) Required Insurance Coverage. Borrower will maintain, and will cause each
Subsidiary to maintain, property and physical damage insurance on selected real and personal
property on an all risks basis (including the perils of flood and quake on a sub-limited basis),
covering the repair and replacement cost of all such selected property. Borrower will also
maintain commercial general liability and excess liability insurance and products/completed
operations liability coverage. Each of the policies described in this clause (a) shall be of the
kinds and in the amounts customarily carried or maintained by Persons of established reputation
engaged in similar businesses and owning similar properties in the same general areas in which the
Borrower or such Subsidiary operates. All such insurance shall be provided by insurers having a
minimum A.M. Best policyholders rating of A-, VII. Borrower will not, and will not permit any of
its Subsidiaries to, bring or keep any article on any business location of Borrower or any of its
Subsidiaries, or cause or allow any condition to exist, if the presence of such article or the
occurrence of such condition would reasonably cause the invalidation of any insurance required by
this Section 5.2, or would otherwise be prohibited by the terms thereof.

     (b) Loss Payee; Additional Insured.

     (i) On or prior to the Effective Date, and at all times thereafter, Borrower will cause
Agent to be named as (A) an additional insured on each liability policy required to be
maintained pursuant to this Section 5.2, and (B) loss payee (which shall include, as
applicable, identification as mortgagee) on each property and physical damage policy
required to be maintained pursuant to this Section 5.2 for any Property Proceeds in
excess of $10,000,000 arising from a single event or related series of events.

     (ii) If (A) Agent receives Property Proceeds in its capacity as loss payee, (B) no
Default or Event of Default exists at such time, and (C) such Property Proceeds are not
required to be applied as a prepayment under the terms of this Agreement, Agent will remit
such Property Proceeds to Borrower within fifteen days after receipt.

-46-

 

     (iii) Agent shall, promptly after the Effective Date, deliver, to Borrower’s insurance
broker for delivery to each insurer that provides a property or physical damage policy on
which Agent is listed as loss payee, a revocable notice that such insurer may pay any
Property Proceeds arising from a single event or related series of events that occurred
prior to the date of this Agreement directly to Borrower; provided that (A) such notice may
be revoked by Agent at any time when a Default or Event of Default exists or any such
Property Proceeds would be required to be applied as a prepayment under the terms of this
Agreement, and (B) any Property Proceeds payable under such policy after receipt by the
insurer of written notice of such revocation shall be paid directly to Agent. If such
Default or Event of Default is cured or waived, the foregoing arrangement may be restored
with respect to future Property Proceeds.

     (iv) All loss payee and additional insured endorsements must be in form and substance
reasonably acceptable to Agent.

     (c) Evidence of Insurance Coverage. Borrower will deliver to Agent on the Effective
Date, an Insurance Certificate from Borrower’s insurance broker dated such date showing the amount
of coverage under all such policies as of such date, showing the endorsements required above, and
showing waivers of all rights of subrogation against all loss payees and additional insureds. Each
such Insurance Certificate will also indicate that each additional insured and loss payee will be
given at least 30 days’ written notice of the cancellation, termination, reduction in amount or
material change in coverage to any part of any applicable policy. Annually, on or prior to June
30, Borrower shall provide Insurance Certificates for all of its insurance policies as of May 1 of
such year and such additional information as to the applicable policies as is reasonably requested
by any Bank. Borrower will deliver to Agent, (i) within 15 days after receipt of notice from any
insurer, a copy of any notice of cancellation or material change in coverage from that existing
under the applicable policy immediately prior to such notice, (ii) as soon as possible but no later
than May 31 of any year, notice of any cancellation or nonrenewal of any insurance policy by the
applicable insurer, if such policy has not been renewed or replaced with a substantially similar
policy, effective as of May 1 of such year, and (iii) notice of any cancellation or nonrenewal of
any insurance policy by Borrower as soon as possible but no later than May 31 of any year.

     Section 5.3. Preservation of Corporate Existence, Etc. The Borrower shall preserve
and maintain, and cause each of its Subsidiaries to preserve and maintain, its corporate existence,
rights, franchises, and privileges in the jurisdiction of its incorporation, and qualify and remain
qualified, and cause each such Subsidiary to qualify and remain qualified, as a foreign corporation
in each jurisdiction in which qualification is necessary or desirable in view of its business and
operations or the ownership of its properties, and, in each case, where failure to qualify or
preserve and maintain its rights and franchises could reasonably be expected to cause a Material
Adverse Change; provided, however, that nothing herein contained shall prevent any
transaction permitted by Section 6.4.

     Section 5.4. Payment of Taxes, Claims, Etc. The Borrower shall pay and discharge, and
cause each of its Subsidiaries to pay and discharge, before the same shall become delinquent,
(a) all taxes, assessments, and governmental charges or levies imposed upon it or upon its income
or profits or Property that are material in amount, prior to the date on which penalties

-47-

 

attach thereto and (b) all lawful claims in excess of $2,500,000 which, if unpaid, might by
law become a Lien upon its Property; provided, however, that neither the Borrower nor any
such Subsidiary shall be required to pay or discharge any such tax, assessment, charge, or levy
which is being contested in good faith and by appropriate proceedings, and with respect to which
reserves required by GAAP have been provided.

     Section 5.5. Visitation Rights. At any reasonable time and from time to time, upon
reasonable notice, the Borrower shall, and shall cause its Subsidiaries to, permit the Agent and
any Bank or any of its agents or representatives thereof, to (a) examine and make copies of and
abstracts from the records and books of account of, and visit and inspect at its reasonable
discretion the properties of, the Borrower and any such Subsidiary, and (b) discuss the affairs,
finances and accounts of the Borrower and any such Subsidiary with any of their respective officers
or directors; provided however, the Agent or the Bank for whose benefit such inspection and
visitation is made assumes sole responsibility for the condition of any property of the Borrower or
its Subsidiaries so visited and inspected, the access and egress thereto (including, but not
limited to wharves, docks, and helicopter landing areas), and any vice or defect therein or
thereon, and assumes all responsibility for and hereby releases and indemnifies the Borrower, its
Affiliates, and their officers, directors, employees, and agents against any claim for damage or
injury to or by the Agent or such Bank (or the representatives thereof) or to the Borrower’s or its
Subsidiaries’ property which may be occasioned by such inspection and visitation of the Borrower’s
or its Subsidiaries’ property.

is material to (y) the Credit Parties’ business or financial condition or (z) the operation and
ownership of the additional Mortgaged Property to which it relates (including without limitation
production, transportation, and marketing of oil and gas produced therefrom), in each case, to the
extent such material Mortgaged Contract prohibits or restricts assignment of the applicable Credit
Party’s rights thereunder to the Agent, unless otherwise agreed by Agent and the Majority Banks,
and (C) take such other actions, approve such other filings, provide such opinions of counsel, and
execute and deliver such other documents as are reasonably requested by the Agent in connection
with the foregoing.

     (b) The Credit Parties shall from time to time execute and deliver, or cause to be executed
and delivered, such additional instruments, certificates or documents, and take such actions, as
the Agent may reasonably request for the purposes of implementing or effectuating the provisions of
this Agreement and the other Credit Documents, or of more fully perfecting or renewing the rights
of the Agent and the Banks with respect to the Collateral (or with respect to any additions thereto
or replacements or proceeds thereof or with respect to any other property or assets hereafter
acquired by any Credit Party which may be part of the Collateral) pursuant hereto or thereto,
including without limitation using commercially reasonable efforts to obtain consents from contract
counterparties with respect to any future Mortgaged Contract that is material to (i) the Credit
Parties’ business or financial condition or (ii) the operation and ownership of the Mortgaged
Property to which it relates (including without limitation production, transportation, and
marketing of oil and gas produced therefrom), in each case, to the extent such material Mortgaged
Contract prohibits or restricts assignment of the applicable Credit Party’s rights thereunder to
the Agent, unless otherwise agreed by Agent and the Majority Banks. Upon the exercise by the Agent
or any Bank of any power, right, privilege or remedy pursuant to this Agreement or the other Credit

governmental consent, approval, recording, qualification or authorization.

     Section 5.12. Title Information and Cure.

     (a) Within 60 days after the delivery to Agent and the Banks of each Oil and Gas Reserve
Report required by Section 5.6, the Borrower shall deliver title information (provided that
no title opinions shall be required) in form and substance reasonably acceptable to Agent covering
enough of the Oil and Gas Properties evaluated by such Oil and Gas Reserve Report that were not
included in the immediately preceding Oil and Gas Reserve Report, so that Agent shall have
received, together with title information previously delivered to Agent, reasonably satisfactory
title information on at least 80% of the Oil and Gas Property Value.

-54-

 

     (b) Within 60 days after notice from Agent that title defects or exceptions (including defects
or exceptions as to priority, but excluding Permitted Borrowing Base Liens) exist with respect to
any Oil and Gas Properties, the Borrower shall either (i) cure any such title defects or
exceptions, (ii) substitute acceptable Mortgaged Properties having an equivalent or greater value
with no title defects or exceptions other than Permitted Borrowing Base Liens or (iii) deliver
title information (provided that no title opinions shall be required) in form and substance
acceptable to Agent so that Agent shall have received, together with title information previously
delivered to Agent, satisfactory title information on at least 80% of the Oil and Gas Property
Value.

     (c) If Borrower is unable to cure any title defect requested by Agent to be cured within the
60-day period referred to in subsection (b) above or Borrower does not comply with the requirements
to provide acceptable title information covering 80% of the Oil and Gas Property Value in
accordance with subsection (b) above, such failure shall not be an Event of Default, but instead
Agent shall have the right to exercise the following remedy in its sole discretion from time to
time while such condition persists, and any failure to so exercise this remedy at any such time
shall not be a waiver as to future exercise of the remedy by Agent or the Banks. To the extent that
Agent is not satisfied with title to any Mortgaged Property after the 60-day period has elapsed,
such unacceptable Mortgaged Property shall not count towards the 80% requirement, and Agent may
send a notice to Borrower and the Banks that the then outstanding Borrowing Base shall be reduced
by 50% of the value given to such unacceptable Mortgaged Property in the most recently delivered
Oil and Gas Reserve Report.

     Section 5.13. Post-Closing Requirements.

     (a) No later than 45 days after the Effective Date, or such later date as shall be agreed to
by the Agent in its sole discretion, the Borrower shall deliver to the Agent title reports
regarding that portion of the Borrowing Base Assets which results in evidence of title satisfactory
to Agent and its counsel covering Borrowing Base Assets representing not less than 80% of the Oil
and Gas Property Value, and such title reports shall not have revealed any condition or
circumstance which would reflect that the representations and warranties contained in Section
4.17 are inaccurate in any material respect.

     (b) No later than 90 days after the Effective Date, or such later date as shall be agreed to
by the Agent in its sole discretion, the Borrower shall execute and deliver to the Agent
supplements to the Mortgages, in form and substance satisfactory to the Agent, for filing in each
jurisdiction where the Mortgages were filed, that expand Exhibit A to each such Mortgage to include
the Contracts (as defined in the Mortgages) related to the Collateral described in such Mortgage.

     (c) As soon as possible after the Effective Date (but no later than 45 days after the
Effective Date, or such later date as shall be agreed to by the Agent in its sole discretion), the
Borrower or its counsel shall file or cause to be filed such forms or documents as may be required
by the Minerals Management Service, the Louisiana State Mineral Board, or any other Governmental
Authority with respect to the Mergers and the Security Documents, in form and substance
satisfactory to the Agent, in each case with the appropriate Governmental Authorities.

-55-

ARTICLE VIII

THE AGENT AND THE ISSUING BANK

     Section 8.1. Appointment and Authorization of Agent.

     (a) Each of the Banks and the Issuing Bank hereby irrevocably appoints Bank of America to act
on its behalf as the Agent hereunder and under the other Credit Documents and authorizes the Agent
to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the
terms hereof or thereof, together with such actions and powers as are reasonably incidental
thereto. The provisions of this Article are solely for the benefit of the Agent, the Banks and the
Issuing Bank, and the Borrower shall not have rights as a third party beneficiary of any of such
provisions except for the Borrower’s consultation rights explicitly set forth in Section
8.6.

     (b) The Issuing Bank shall act on behalf of the Banks with respect to any Letters of Credit
issued by it and the documents associated therewith, and the Issuing Bank shall have all of the
benefits and immunities (i) provided to the Agent in this Article VIII 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 applications and agreements for letters of credit
pertaining to such Letters of Credit as fully as if the term “Agent” as used in this Article
VIII and in the definition of “Agent-Related Person” included the Issuing Bank with respect to
such acts or omissions, and (ii) as additionally provided herein with respect to the Issuing Bank.

     Section 8.2. Rights as a Bank. The Person serving as the Agent hereunder shall have
the same rights and powers in its capacity as a Bank as any other Bank and may exercise the
same as though it were not the Agent and the term “Bank” or “Banks” shall, unless otherwise
expressly indicated or unless the context otherwise requires, include the Person serving as the
Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits

-66-

 

from, lend money to, act as the financial advisor or in any other advisory capacity for and
generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if such Person were not the Agent hereunder and without any duty to account therefor to
the Banks.

     Section 8.3. Exculpatory Provisions. The Agent shall not have any duties or
obligations except those expressly set forth herein and in the other Credit Documents. Without
limiting the generality of the foregoing, the Agent:

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

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

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

     The Agent shall not be liable for any action taken or not taken by it (i) with the consent or
at the request of the Majority Banks (or such other number or percentage of the Banks as shall be
necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances
as provided in Article VII and Section 9.1) or (ii) in the absence of its own gross
negligence or willful misconduct. The Agent shall be deemed not to have knowledge of any Default
unless and until notice describing such Default is given to the Agent by the Borrower, a Bank or
the Issuing Bank.

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

     Section 8.4. Reliance by Agent. The Agent shall be entitled to rely upon, and shall
not incur any liability for relying upon, any notice, request, certificate, consent, statement,
instrument, document or other writing (including any electronic message, internet or intranet

-67-

 

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

     Section 8.5. Delegation of Duties. The Agent may perform any and all of its duties
and exercise its rights and powers hereunder or under any other Credit Document by or through any
one or more sub-agents appointed by the Agent. The Agent and any such sub-agent may perform any
and all of its duties and exercise its rights and powers by or through their respective Related
Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the
Related Parties of the Agent and any such sub-agent, and shall apply to their respective activities
in connection with the syndication of the credit facilities provided for herein as well as
activities as Agent.

     Section 8.6. Resignation of Agent. The Agent may at any time give notice of its
resignation to the Banks, the Issuing Bank and the Borrower. Upon receipt of any such notice of
resignation, the Majority Banks shall have the right, in consultation with the Borrower, to appoint
a successor, which shall be a bank with an office in the United States, or an Affiliate of any such
bank with an office in the United States. If no such successor shall have been so appointed by the
Majority Banks and shall have accepted such appointment within 30 days after the retiring Agent
gives notice of its resignation, then the retiring Agent may on behalf of the Banks and the Issuing
Bank, appoint a successor Agent meeting the qualifications set forth above; provided that
if the Agent shall notify the Borrower and the Banks that no qualifying Person has accepted such
appointment, then such resignation shall nonetheless become effective in accordance with such
notice and (1) the retiring Agent shall be discharged from its duties and obligations hereunder and
under the other Credit Documents (except that in the case of any collateral security held by the
Agent on behalf of the Banks or the Issuing Bank under any of the Credit Documents, the retiring
Agent shall continue to hold such collateral security until such time as a successor Agent is
appointed) and (2) all payments, communications and determinations provided to be made by, to or
through the Agent shall instead be made by or to each Bank and the Issuing Bank directly, until
such time as the Majority Banks appoint a successor Agent as provided for above in this Section.
Upon the acceptance of a successor’s appointment as Agent hereunder, such successor shall succeed
to and become vested with all of the rights, powers, privileges and duties of the retiring (or
retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations
hereunder or under the other Credit Documents (if not already discharged therefrom as provided
above in this Section). The fees
payable by the Borrower to a successor Agent shall be the same as those payable to its
predecessor unless otherwise agreed between the Borrower and such successor. After the retiring
Agent’s resignation hereunder and under the other Credit Documents, the provisions of

-68-

 

this Article and Section 10.04 shall continue in effect for the benefit of such
retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while the retiring Agent was acting as Agent.

Any resignation by Bank of America as Agent pursuant to this Section shall also constitute its
resignation as Issuing Bank. Upon the acceptance of a successor’s appointment as Agent hereunder,
(a) such successor shall succeed to and become vested with all of the rights, powers, privileges
and duties of the retiring Issuing Bank, (b) the retiring Issuing Bank shall be discharged from all
of their respective duties and obligations hereunder or under the other Credit Documents, and (c)
the successor Issuing Bank shall issue letters of credit in substitution for the Letters of Credit,
if any, outstanding at the time of such succession or make other arrangements satisfactory to the
retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank with
respect to such Letters of Credit.

     Section 8.7. Non-Reliance on Agent and Other Banks. Each Bank and the Issuing Bank
acknowledges that it has, independently and without reliance upon the Agent or any other Bank or
any of their Related Parties and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank and
the Issuing Bank also acknowledges that it will, independently and without reliance upon the Agent
or any other Bank or any of their Related Parties and based on such documents and information as it
shall from time to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any other Credit Document or any related
agreement or any document furnished hereunder or thereunder.

     Section 8.8. No Other Duties, Etc. Anything herein to the contrary notwithstanding,
none of the Syndication Agents, Co-Documentation Agents, Managing Agents, Bookrunners, or Lead
Arrangers listed on the cover page hereof shall have any powers, duties or responsibilities under
this Agreement or any of the other Credit Documents, except in its capacity, as applicable, as the
Agent, a Bank, or the Issuing Bank hereunder.

     Section 8.9. Agent May File Proofs of Claim. In case of the pendency of any
proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Credit
Party, the Agent (irrespective of whether the principal of any Advance or Letter of Credit
Obligation shall then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Agent shall have made any demand on the Borrower) shall be entitled and
empowered, by intervention in such proceeding or otherwise:

     (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Advances, Letter of Credit Obligations and all other Obligations that are
owing and unpaid and to file such other documents as may be necessary or advisable in order to have
the claims of the Banks, the Issuing Bank and the Agent (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Banks, the Issuing Bank and the Agent and
their respective agents and counsel and all other amounts due the Banks, the Issuing Bank and the
Agent under Sections 2.7 and 9.4) allowed in such judicial proceeding; and

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

-69-

 

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Bank and the Issuing Bank to make such
payments to the Agent and, in the event that the Agent shall consent to the making of such payments
directly to the Banks and the Issuing Bank, to pay to the Agent any amount due for the reasonable
compensation, expenses, disbursements and advances of the Agent and its agents and counsel, and any
other amounts due the Agent under Sections 2.7 and 9.4.

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

     Section 8.10. Collateral and Guaranty Matters. The Banks and the Issuing Bank
irrevocably authorize the Agent, at its option and in its discretion,

(a) to release any Lien on any property granted to or held by the Agent under any Credit
Document (i) upon termination of the Commitments and payment in full of all Obligations
(other than contingent indemnification obligations) and the expiration or termination of all
Letters of Credit, (ii) that is sold or to be sold as part of or in connection with any sale
permitted hereunder or under any other Credit Document, or (iii) subject to Section
9.1, if approved, authorized or ratified in writing by the Majority Banks;

(b) to release any Lien on any Mortgaged Property granted to or held by the Agent under the
Mortgages, so long as (i) after giving effect to such release, the Mortgaged Property Value
shall not be less than 80% of the Oil and Gas Property Value as set forth in the most recent
Oil and Gas Reserve Report, (ii) the Borrower shall deliver to the Agent a certificate in
the form of Exhibit I hereto, which sets forth the calculation of Mortgaged Property
Value and demonstrates and certifies that such Mortgaged Property Value equals or exceeds
80% of the Oil and Gas Property Value, after giving effect to such release of Mortgaged
Property, and (iii) the Borrower identifies in writing on such certificate the Mortgaged
Properties to be released and sets forth the value attributed thereto in the most recent Oil
and Gas Reserve Report;

(c) to subordinate any Lien on any property granted to or held by the Agent under any Credit
Document to the holder of any Lien on such property that is permitted by Section
6.2(c); and

(d) to release any Guarantor from its obligations under any Guaranty if such Person ceases
to be a Subsidiary as a result of a transaction permitted hereunder.

Upon request by the Agent at any time, the Majority Banks will confirm in writing the Agent’s
authority to release or subordinate its interest in particular types or items of property, or to
release any Guarantor from its obligations under any Guaranty pursuant to this Section
8.10.

-70-

 

     Section 8.11. Indemnification of Agent. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED
HEREBY ARE CONSUMMATED, THE BANKS SHALL INDEMNIFY UPON DEMAND EACH AGENT-RELATED PERSON (TO THE
EXTENT NOT REIMBURSED BY OR ON BEHALF OF BORROWER AND WITHOUT LIMITING THE OBLIGATION OF BORROWER
TO DO SO), PRO RATA (AS DETERMINED AT THE TIME INDEMNIFICATION IS SOUGHT HEREUNDER), AND HOLD
HARMLESS EACH AGENT-RELATED PERSON FROM AND AGAINST ANY AND ALL INDEMNIFIED LIABILITIES INCURRED BY
IT; PROVIDED, HOWEVER, THAT NO BANK SHALL BE LIABLE FOR THE PAYMENT TO ANY
AGENT-RELATED PERSON OF ANY PORTION OF SUCH INDEMNIFIED LIABILITIES TO THE EXTENT DETERMINED IN A
FINAL, NONAPPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED FROM SUCH
AGENT-RELATED PERSON’S OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT; PROVIDED,
HOWEVER, THAT NO ACTION TAKEN IN ACCORDANCE WITH THE DIRECTIONS OF THE MAJORITY BANKS SHALL
BE DEEMED TO CONSTITUTE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT FOR PURPOSES OF THIS SECTION.
WITHOUT LIMITATION OF THE FOREGOING, EACH BANK SHALL REIMBURSE THE AGENT UPON DEMAND FOR ITS
RATABLE SHARE (AS DETERMINED AT THE TIME INDEMNIFICATION IS SOUGHT HEREUNDER) OF ANY COSTS OR
OUT-OF-POCKET EXPENSES (INCLUDING ALL FEES, EXPENSES, AND DISBURSEMENTS OF ANY LAW FIRM OR OTHER
EXTERNAL COUNSEL AND, WITHOUT DUPLICATION, THE ALLOCATED COST OF INTERNAL LEGAL SERVICES AND ALL
EXPENSES AND DISBURSEMENTS OF INTERNAL COUNSEL) INCURRED BY THE 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 CREDIT DOCUMENT, OR ANY DOCUMENT CONTEMPLATED BY
OR REFERRED TO HEREIN, TO THE EXTENT THAT THE 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 OTHER OBLIGATIONS, AND THE RESIGNATION OF THE AGENT.

ARTICLE IX

Agreement or any other Credit Document. Notwithstanding anything to the contrary herein, no
Defaulting Bank shall have any right to approve or disapprove any amendment, waiver, or consent
hereunder, except that the Commitment of such Bank may not be increased or extended without the
consent of such Bank.

     Section 9.2. Notices, Etc.

     (a) Except as provided in clause (b) below, all notices and other communications shall be in
writing (including, without limitation, telecopy or telex) and mailed by certified mail, return
receipt requested, telecopied, telexed, hand delivered, or delivered by a nationally recognized
overnight courier, at the address for the appropriate party specified in Annex 1 or at such
other address as shall be designated by such party in a written notice to the other parties. All
such notices and communications shall, when so mailed, telecopied, telexed, or hand delivered or

pursuant to Article II or VIII shall not be effective until received by the Agent, and (ii) notices
delivered through electronic communications pursuant to clause (b) below shall be effective as
provided in such clause (b).

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

Unless the Agent otherwise prescribes, (i) notices and other communications sent to an e-mail
address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended
recipient (such as by the “return receipt requested” function, as available, return e-mail or other
written acknowledgement), provided that if such notice or other communication is not sent
during the normal business hours of the recipient, such notice or communication shall be

-72-

 

deemed to have been sent at the opening of business on the next business day for the recipient, and
(ii) notices or communications posted to an internet or intranet website shall be deemed received
upon the deemed receipt by the intended recipient at its e-mail address as described in the
foregoing clause (i) of notification that such notice or communication is available and identifying
the website address therefor.

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

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

     (e) Reliance by Agent, Issuing Bank, and Banks. The Agent, Issuing Bank and the Banks
shall be entitled to rely and act upon any notices (including telephonic Notices of Borrowing)
purportedly given by or on behalf of the Borrower even if (i) such notices were not made in a
manner specified herein, were incomplete or were not preceded or followed by any

-73-

 

other form of notice specified herein, or (ii) the terms thereof, as understood by the
recipient, varied from any confirmation thereof. The Borrower shall indemnify the Agent, the
Issuing Bank, each Bank and the Related Parties of each of them from all losses, costs, expenses
and liabilities resulting from the reliance by such Person on each notice purportedly given by or
on behalf of the Borrower. All telephonic notices to and other telephonic communications with the
Agent may be recorded by the Agent, and each of the parties hereto hereby consents to such
recording.

     Section 9.3. No Waiver; Remedies. No failure on the part of any Bank, the Agent, or
the Issuing Bank to exercise, and no delay in exercising, any right hereunder or under any Note
shall operate as a waiver thereof; nor shall any single or partial exercise of any such right
preclude any other or further exercise thereof or the exercise of any other right. The remedies
herein provided are cumulative and not exclusive of any remedies provided by law.

     Section 9.4. Costs and Expenses. The Borrower agrees to pay on demand (a) all
reasonable out-of-pocket costs and expenses of the Agent in connection with the syndication of the
credit facilities provided for herein, the preparation, execution, delivery, administration,
modification, and amendment of this Agreement, the Notes, the Guaranties, the Security Documents,
and the other Credit Documents including, without limitation, the reasonable fees and out-of-pocket
expenses of counsel for the Agent with respect to advising the Agent as to its rights and
responsibilities under this Agreement, and (b) all out-of-pocket costs and expenses, if any, of the
Agent, the Issuing Bank, and each Bank (including, without limitation, reasonable counsel fees and
expenses of the Agent, the Issuing Bank, and each Bank) in connection with the enforcement (whether
through negotiations, legal proceedings, or otherwise) of this Agreement, the Notes, the
Guaranties, the Security Documents and the other Credit Documents. The agreements in this Section
shall survive the resignation of the Agent, the replacement of any Bank, the termination of the
Commitments, and the repayment, satisfaction or discharge of all the other Obligations.

     Section 9.5. Binding Effect. This Agreement shall become effective when it shall have
been executed by the Borrower and the Agent, and when the Agent shall have, as to each Bank, either
received a counterpart hereof executed by such Bank or been notified by such Bank that such Bank
has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the
Agent, the Issuing Bank, and each Bank and their respective successors and assigns, except that the
Borrower shall not have the right to assign its rights or delegate its duties under this Agreement
or any interest in this Agreement without the prior written consent of each Bank.

     Section 9.6. Bank Assignments and Participations.

     (a) Successors and Assigns Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of
its rights or obligations hereunder without the prior written consent of the Agent and each
Bank and no Bank may assign or otherwise transfer any of its rights or obligations hereunder except
(i) to an assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way
of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by
way

-74-

 

of pledge or assignment of a security interest subject to the restrictions of subsection (f) of
this Section (and any other attempted assignment or transfer by any party hereto shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in subsection (d) of this Section and, to the extent expressly
contemplated hereby, the Related Parties of each of the Agent, the Issuing Bank and the Banks) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

     (b) Assignments by Banks. Any Bank may at any time assign to one or more assignees
all or a portion of its rights and obligations under this Agreement (including all or a portion of
its Commitment and the Advances (including for purposes of this subsection (b), participations in
Letter of Credit Obligations) at the time owing to it); provided that any such assignment
shall be subject to the following conditions:

     (i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning
Bank’s Commitment and the Advances at the time owing to it or in the case of an
assignment to a Bank, an Affiliate of a Bank or an Approved Fund, no minimum amount
need be assigned; and

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

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

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

(A) the consent of the Borrower (such consent not to be unreasonably withheld or
delayed) shall be required unless (1) an Event of Default has occurred and is

-75-

 

continuing at the time of such assignment or (2) such assignment is to a Bank, an
Affiliate of a Bank or an Approved Fund;

(B) the consent of the Agent (such consent not to be unreasonably withheld or
delayed) shall be required if such assignment is to a Person that is not a Bank, an
Affiliate of such Bank or an Approved Fund with respect to such Bank; and

(C) the consent of the Issuing Bank (such consent not to be unreasonably withheld or
delayed) shall be required for any assignment that increases the obligation of the
assignee to participate in exposure under one or more Letters of Credit (whether or
not then outstanding).

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

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

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

Subject to acceptance and recording thereof by the Agent pursuant to subsection (c) of this
Section, from and after the effective date specified in each Assignment and Assumption, the
assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Bank under this Agreement,
and the assigning Bank thereunder shall, to the extent of the interest assigned by such Assignment
and Assumption, be released from its obligations under this Agreement (and, in the case of an
Assignment and Assumption covering all of the assigning Bank’s rights and obligations under this
Agreement, such Bank shall cease to be a party hereto) but shall continue to be entitled to the
benefits of Sections 2.11, 2.12, 2.13, 9.4, and 9.7 with respect to facts and circumstances
occurring prior to the effective date of such assignment. Upon request, the Borrower (at its
expense) shall execute and deliver a Note to the assignee Bank. Any assignment or transfer by a
Bank 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 Bank of a participation in such rights
and obligations in accordance with subsection (d) of this Section.

     (c) Register. The Agent, acting solely for this purpose as an agent of the Borrower,
shall maintain at the Agent’s Office a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Banks, and the Commitments of, and
principal amounts of the Advances and Letter of Credit Obligations owing to, each Bank pursuant to
the terms hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Agent and the Banks may treat each Person whose name is recorded
in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this

-76-

 

Agreement, notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower and any Bank, at any reasonable time and from time to time upon
reasonable prior notice.

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

Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that
such Bank 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 Bank will not, without the consent of the Participant, agree to
any amendment, waiver or other modification described in the first proviso to Section 9.1
that affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that
each Participant shall be entitled to the benefits of Sections 2.11, 2.12, and
2.13 to the same extent as if it were a Bank and had acquired its interest by assignment
pursuant to subsection (b) of this Section. To the extent permitted by law, each Participant also
shall be entitled to the benefits of Section 7.4 as though it were a Bank, provided
such Participant agrees to be subject to Section 2.10 as though it were a Bank.

     (e) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Section 2.12 or 2.13 than the applicable Bank
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 Bank if it were a Bank shall not be entitled to the
benefits of Section 2.13 unless the Borrower is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrower, to comply with
Section 2.13(d) as though it were a Bank.

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

     (g) Electronic Execution of Assignments. The words “execution,” “signed,”
“signature,” and words of like import in any Assignment and Assumption shall be deemed to include
electronic signatures or the keeping of records in electronic form, each of which shall be of the
same legal effect, validity or enforceability as a manually executed signature or the use of

-77-

 

a paper-based recordkeeping system, as the case may be, to the extent and as provided for in
any applicable law, including the Federal Electronic Signatures in Global and National Commerce
Act, the New York State Electronic Signatures and Records Act, or any other similar state laws
based on the Uniform Electronic Transactions Act.

     (h) Resignation as Issuing Bank after Assignment. Notwithstanding anything to the
contrary contained herein, if at any time Bank of America assigns all of its Commitment and
Advances pursuant to subsection (b) above, Bank of America may, upon 30 days’ notice to the
Borrower and the Banks, resign as Issuing Bank. In the event of any such resignation as Issuing
Bank, the Borrower shall be entitled to appoint from among the Banks a successor Issuing Bank
hereunder; provided, however, that no failure by the Borrower to appoint any such
successor shall affect the resignation of Bank of America as Issuing Bank. If Bank of America
resigns as Issuing Bank, it shall retain all the rights, powers, privileges and duties 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 Letter of Credit Obligations with respect thereto
(including the right to require the Banks to make Advances or fund risk participations in
unreimbursed amounts pursuant to Section 2.6(d)). Upon the appointment of a successor
Issuing Bank, (a) such successor shall succeed to and become vested with all of the rights, powers,
privileges and duties of the retiring Issuing Bank, and (b) the successor Issuing Bank shall issue
letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of
such succession or make other arrangements satisfactory to Bank of America to effectively assume
the obligations of Bank of America with respect to such Letters of Credit.

     Section 9.7. Indemnification. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE
CONSUMMATED, THE BORROWER SHALL INDEMNIFY AND HOLD HARMLESS EACH AGENT-RELATED PERSON, EACH BANK
AND THEIR RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, COUNSEL, AGENTS AND
ATTORNEYS-IN-FACT (COLLECTIVELY THE “INDEMNITEES”) FROM AND AGAINST ANY AND ALL
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, CLAIMS, DEMANDS, ACTIONS, JUDGMENTS, SUITS,
COSTS, EXPENSES, AND DISBURSEMENTS (INCLUDING ALL FEES, EXPENSES, AND DISBURSEMENTS OF ANY LAW FIRM
OR OTHER EXTERNAL COUNSEL AND, WITHOUT DUPLICATION, THE ALLOCATED COST OF INTERNAL LEGAL SERVICES
AND ALL EXPENSES AND DISBURSEMENTS OF INTERNAL COUNSEL AND INCLUDING SETTLEMENT COSTS) OF ANY KIND
OR NATURE WHATSOEVER, (EXCLUDING, HOWEVER, THE COSTS AND EXPENSES INCURRED BY THE BANKS, OTHER THAN
THE AGENT, IN CONNECTION WITH THE PREPARATION, EXECUTION OR DELIVERY OF THIS AGREEMENT) WHICH MAY
AT ANY TIME BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST ANY SUCH INDEMNITEE IN ANY WAY RELATING
TO OR ARISING OUT OF OR IN CONNECTION WITH (A) THE EXECUTION, DELIVERY, ENFORCEMENT, PERFORMANCE OR
ADMINISTRATION OF ANY CREDIT DOCUMENT OR ANY OTHER AGREEMENT, LETTER, OR INSTRUMENT DELIVERED IN
CONNECTION WITH THE TRANSACTIONS CONTEMPLATED THEREBY OR THE CONSUMMATION OF THE TRANSACTIONS
CONTEMPLATED THEREBY, (B) ANY COMMITMENT, ADVANCE, OR LETTER OF CREDIT OR THE USE OR PROPOSED USE
OF THE PROCEEDS THEREFROM (INCLUDING ANY REFUSAL BY THE ISSUING BANK TO HONOR A

-78-

 

DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH
DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT), OR (C) ANY ACTUAL OR
ALLEGED PRESENCE OR RELEASE OF HAZARDOUS WASTE OR HAZARDOUS SUBSTANCES ON OR FROM ANY PROPERTY
CURRENTLY OR FORMERLY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR ANY
LIABILITY UNDER ENVIRONMENTAL LAW RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR
(D) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE
FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY (INCLUDING ANY INVESTIGATION OF,
PREPARATION FOR, OR DEFENSE OF ANY PENDING OR THREATENED CLAIM, INVESTIGATION, LITIGATION OR
PROCEEDING) AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO (ALL THE FOREGOING,
COLLECTIVELY, THE “INDEMNIFIED LIABILITIES”), IN ALL CASES, WHETHER OR NOT CAUSED BY OR
ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY, OR SOLE NEGLIGENCE OF THE
INDEMNITEE; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO
THE EXTENT THAT SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, CLAIMS, DEMANDS,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS ARE DETERMINED BY A COURT OF COMPETENT
JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF SUCH INDEMNITEE. NO INDEMNITEE SHALL BE LIABLE FOR ANY DAMAGES ARISING FROM
THE USE BY OTHERS OF ANY INFORMATION OR OTHER MATERIALS OBTAINED THROUGH INTRALINKS OR OTHER
SIMILAR INFORMATION TRANSMISSION SYSTEMS IN CONNECTION WITH THIS AGREEMENT, NOR SHALL ANY
INDEMNITEE HAVE ANY LIABILITY FOR ANY INDIRECT OR CONSEQUENTIAL DAMAGES RELATING TO THIS AGREEMENT
OR ANY OTHER CREDIT DOCUMENT OR ARISING OUT OF ITS ACTIVITIES IN CONNECTION HEREWITH OR THEREWITH
(WHETHER BEFORE OR AFTER THE EFFECTIVE DATE). ALL AMOUNTS DUE UNDER THIS SECTION 9.7 SHALL
BE PAYABLE WITHIN TEN BUSINESS DAYS AFTER DEMAND THEREFOR. THE AGREEMENTS IN THIS SECTION SHALL
SURVIVE THE RESIGNATION OF THE AGENT, THE REPLACEMENT OF ANY BANK, THE TERMINATION OF THE
COMMITMENTS, AND THE REPAYMENT, SATISFACTION OR DISCHARGE OF ALL THE OTHER OBLIGATIONS.

     Section 9.8. USA Patriot Act Notice. Each Bank that is subject to the Act (as
hereinafter defined) and the Agent (for itself and not on behalf of any Bank) hereby notifies the
Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and
record information that identifies the Borrower, which information includes the name and address of
the Borrower and other information that will allow such Bank or the Agent, as applicable, to
identify the Borrower in accordance with the Act.

     Section 9.9. No Advisory or Fiduciary Responsibility. In connection with all aspects
of each transaction contemplated hereby (including in connection with any amendment, waiver

-79-

 

or other modification hereof or of any other Credit Document), the Borrower acknowledges and
agrees, and acknowledges its Affiliates’ understanding, that: (i) (A) the arranging and other
services regarding this Agreement provided by the Agent and the Arranger are arm’s-length
commercial transactions between the Borrower and its Affiliates, on the one hand, and the Agent and
the Arranger, on the other hand, (B) the Borrower has consulted its own legal, accounting,
regulatory and tax advisors to the extent it has deemed appropriate, and (C) the Borrower is
capable of evaluating, and understands and accepts, the terms, risks and conditions of the
transactions contemplated hereby and by the other Credit Documents; (ii) (A) the Agent and the
Arranger each is and has been acting solely as a principal and, except as expressly agreed in
writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent
or fiduciary for the Borrower or any of its Affiliates, or any other Person and (B) neither the
Agent nor the Arranger has any obligation to the Borrower or any of its Affiliates with respect to
the transactions contemplated hereby except those obligations expressly set forth herein and in the
other Credit Documents; and (iii) the Agent and the Arranger and their respective Affiliates may be
engaged in a broad range of transactions that involve interests that differ from those of the
Borrower and its Affiliates, and neither the Agent nor the Arranger has any obligation to disclose
any of such interests to the Borrower or its Affiliates. To the fullest extent permitted by law,
the Borrower hereby waives and releases any claims that it may have against the Agent and the
Arranger with respect to any breach or alleged breach of agency or fiduciary duty in connection
with any aspect of any transaction contemplated hereby.

     Section 9.10. Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and
the same agreement.

     Section 9.11. Survival of Representations, Etc. All representations and warranties
contained in this Agreement or made in writing by or on behalf of the Borrower in connection
herewith shall survive the execution and delivery of this Agreement and the Credit Documents, the
making of the Advances and any investigation made by or on behalf of the Banks, none of which
investigations shall diminish any Bank’s right to rely on such representations and warranties. All
obligations of the Borrower provided for in Sections 2.11, 2.12, 2.13(c), 9.4, and
9.7 and all of the obligations of the Banks in Section 8.7 shall survive any
termination of this Agreement and repayment in full of the Obligations.

     Section 9.12. Severability. In case one or more provisions of this Agreement or the
other Credit Documents shall be invalid, illegal or unenforceable in any respect under any
applicable law, the validity, legality, and enforceability of the remaining provisions contained
herein or therein shall not be affected or impaired thereby.

     Section 9.13. Business Loans. The Borrower warrants and represents that the Advances
evidenced by the Notes are and shall be for business, commercial, investment, or other similar
purposes and not primarily for personal, family, household, or agricultural use, as such terms are
used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any,
as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate
ceiling” (as such term is defined in Chapter One) from time to time in effect.

-80-

 

     Section 9.14. Amendment and Restatement. This Agreement represents an amendment and
restatement of the Existing Credit Agreement. Any indebtedness under the Existing Credit Agreement
continues under this Agreement, and the execution of this Agreement does not indicate a payment,
satisfaction, novation, or discharge thereof.

     Section 9.15. Governing Law. This Agreement, the Notes and the other Credit Documents
shall be governed by, and construed and enforced in accordance with, the laws of the State of
Texas. Without limiting the intent of the parties set forth above, Chapter 346 the Texas Finance
Code, as amended, shall not apply to this Agreement, the Notes, or the transactions contemplated
hereby. Each Letter of Credit shall be governed by the Uniform Customs and Practice for
Documentary Credits, International Chamber of Commerce Publication No. 500 (1993 version).

UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND

PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT
OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT OR IN ANY OTHER CREDIT DOCUMENT
SHALL AFFECT ANY RIGHT THAT THE AGENT, ANY BANK OR THE ISSUING BANK MAY OTHERWISE HAVE TO BRING ANY
ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT AGAINST THE BORROWER
OR ANY OTHER CREDIT PARTY OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

     (b) WAIVER OF VENUE. THE BORROWER AND EACH OTHER CREDIT PARTY IRREVOCABLY AND
UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY ANY LEGAL REQUIREMENT, ANY OBJECTION
THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH
(a) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION

IN THE MANNER PROVIDED FOR NOTICES IN SECTION 9.2. NOTHING IN THIS AGREEMENT WILL AFFECT
THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY ANY LEGAL
REQUIREMENT.

     (d) WAIVER OF PUNITIVE DAMAGES, ETC. EACH CREDIT PARTY HEREBY (i) IRREVOCABLY WAIVES,
TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, (A) ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY
LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN
CONNECTION WITH THE CREDIT DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED
THEREWITH, ANY “SPECIAL DAMAGES,” AS DEFINED BELOW; AND (B) ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR
ANY OTHER CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON

AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH

INCLUDE ANY PAYMENT OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY
OTHER PARTY HERETO.

     (e) WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER CREDIT
DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY
OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE
OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     Section 9.17. Treatment of Certain Information; Confidentiality.

-82-

 

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

For purposes of this Section, “Information” means all information received from the
Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective
businesses, other than any such information that is available to the Agent, any Bank, or the
Issuing Bank on a nonconfidential basis prior to disclosure by the Borrower or any Subsidiary,
provided that, in the case of information received from the Borrower or any Subsidiary
after the date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

Each of the Agent, the Banks, and the Issuing Bank acknowledges that (a) the Information may
include material non-public information concerning the Borrower or a Subsidiary, as the case may
be, (b) it has developed compliance procedures regarding the use of material non-public information
and (c) it will handle such material non-public information in accordance with applicable Legal
Requirements, including United States federal and state securities laws.

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

     THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

ASSIGNMENT AND ACCEPTANCE

[date]

     Reference is made to the Second Amended and Restated Credit Agreement dated as of August
[___], 2008 (as the same may be modified from time to time, the “Credit
Agreement”), among
Stone Energy Corporation, a Delaware corporation (“Borrower”), the banks named therein
(“Banks”), and Bank of America, N.A., as administrative agent for the Banks
(“Agent”). Capitalized terms used herein but not defined herein shall have the meanings
specified by the Credit Agreement.

     Pursuant to the terms of the Credit Agreement,
[     ] (“Assignor”), wishes to assign and
delegate to [     ] (“Assignee”), [     ]%1 of its rights and obligations under the
Credit Agreement. Therefore, Assignor, Assignee, and the Agent agree as follows:

     1. The Assignor hereby sells and assigns and delegates to the Assignee, and the Assignee
hereby purchases and assumes from the Assignor, without recourse to the Assignor and without
representation or warranty except for the representations and warranties specifically set forth in
clauses (i), (ii), and (iii) of Section 2 of this Assignment and Acceptance, a [     ]%
interest in and to all of the Assignor’s rights and obligations under the Credit Agreement and the
other Credit Documents as of the Effective Date (as defined below), including such percentage
interest in the Assignor’s Commitment, the Advances owing to the Assignor, and the Note held by the
Assignor.

     2. The Assignor (i) represents and warrants that, prior to executing this Assignment and
Acceptance, its Commitment is $[     ], the aggregate outstanding principal amount of Advances owed by
the Borrower to the Assignor is $[     ], and its Pro Rata Share of the Letter of Credit Exposure is
$[     ]; (ii) represents and warrants that it is the legal and beneficial owner of the interest being
assigned by it hereunder and that such interest is free and clear of any adverse claim; (iii) makes
no representation or warranty and assumes no responsibility with respect to any statements,
warranties, or representations made in or in connection with the Credit Agreement or any other
Credit Document or the execution, legality, validity, enforceability, genuineness, sufficiency, or
value of the Credit Agreement or any other Credit Document or any other instrument or document
furnished pursuant thereto; (iv) makes no representation or warranty and assumes no responsibility
with respect to the financial condition of the Borrower or any Guarantor or the performance or
observance by the Borrower or any Guarantor of any of its obligations under the Credit Agreement or
any other Credit Document or any other instrument or document furnished pursuant thereto; and (v)
attaches the Note referred to in Section 1 above and requests that the Agent exchange such
Note for a new Note dated [     ], in the principal

 

			
	1	 	Specify percentage to 4 decimal points.

 

 

amount of $[      ] payable to the order of the Assignee and a new Note dated
[      ], in the principal amount of $[ ] payable to the order of Assignor.

     3. The Assignee (i) confirms that it has received a copy of the Credit Agreement, together
with copies of the financial statements referred to in Section 4.05 thereof and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision
to enter into this Assignment and Acceptance; (ii) agrees that it will, independently and without
reliance upon the Agent, the Assignor, or any other Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Credit Agreement or any other Credit Document; (iii) appoints
and authorizes the Agent to take such action as agent on its behalf and to exercise such powers
under the Credit Agreement and any other Credit Document as are delegated to the Agent by the terms
thereof, together with such powers as are reasonably incidental thereto; (iv) agrees that it will
perform in accordance with their terms all of the obligations which by the terms of the Credit
Agreement or any other Credit Document are required to be performed by it as a Bank; (v) specifies
as its Domestic Lending Office (and address for notices) and Eurodollar Lending Office the offices
set forth beneath its name on the signature pages hereof; (vi) attaches the forms prescribed by the
Internal Revenue Service of the United States certifying as to the Assignee’s status for purposes
of determining exemption from United States withholding taxes with respect to all payments to be
made to the Assignee under the Credit Agreement and the Note or such other documents as are
necessary to indicate that all such payments are subject to such rates at a rate reduced by an
applicable tax treaty2, and (vii) represents that it is an Eligible Assignee.

     4. The effective date for this Assignment and Acceptance shall be [___] (“Effective
Date”)3, and following the execution of this Assignment and Acceptance, the Agent
will record it in the Register.

     5. Upon such recording, and as of the Effective Date, (i) the Assignee shall be a party to the
Credit Agreement for all purposes, and, to the extent provided in this Assignment and Acceptance,
have the rights and obligations of a Bank thereunder and (ii) the Assignor shall, to the extent
provided in this Assignment and Acceptance, relinquish its rights (other than rights against the
Borrower pursuant to Sections 9.4 and 9.7 of the Credit Agreement, which shall
survive this agreement) and be released from its obligations (other than obligations to the Agent
pursuant to Section 8.7 of the Credit Agreement, which shall survive this agreement) under
the Credit Agreement.

     6. Upon such recording, from and after the Effective Date, the Agent shall make all payments
under the Credit Agreement and the Note in respect of the interest assigned hereby (including all
payments of principal, interest, and fees) to the Assignee. The Assignor and Assignee shall make
all appropriate adjustments in payments under the Credit Agreement and the Notes for periods prior
to the Effective Date directly between themselves.

EXHIBIT C

FORM OF GUARANTY

GUARANTY

     This Guaranty dated as of August [___], 2008 (“Agreement”), is made by the undersigned
Subsidiaries of Stone Energy Corporation (collectively the “Guarantors”), in favor of the
Agent for the benefit of the Agent and the Banks referred to below.

INTRODUCTION

     This Guaranty is given in connection with the Second Amended and Restated Credit Agreement
dated as of August [___], 2008 (as the same may be modified from time to time, the “Credit
Agreement”), among Stone Energy Corporation, a Delaware corporation (“Borrower”), the
banks named therein (“Banks”), and Bank of America, N.A., as administrative agent for the
Banks (“Agent”). Capitalized terms used herein but not defined herein shall have the
meanings specified by the Credit Agreement. As a condition precedent to the extension of credit
under the Credit Agreement, the Agent and the Banks require the Guarantors to enter into this
Agreement. Each Guarantor believes that it will obtain substantial direct and indirect benefit
from the credit extended to the Borrower by the Banks under the Credit Agreement.

     In consideration of the foregoing and for other valuable consideration received, each
Guarantor agrees as follows:

     ARTICLE I Guaranty.

     Section 1.1. Each Guarantor irrevocably guarantees to the Agent the full payment of (a) all
principal, interest, fees, reimbursements, indemnifications, and other amounts now or hereafter
owed by the Borrower to the Agent and the Banks under the Credit Agreement and the other Credit
Documents, and (b) any increases, extensions, and rearrangements of the foregoing obligations under
any amendments, supplements, and other modifications of the documents and agreements creating the
foregoing obligations (collectively, the “Guaranteed Obligations”). This is a guaranty of
payment and not merely a guaranty of collection, and each Guarantor is liable as a primary obligor.
If any of the Guaranteed Obligations are not punctually paid when due, whether by maturity,
acceleration, or otherwise, the Guarantors shall immediately pay to the Agent, for the ratable
benefit of the Banks, the full amount due. Each Guarantor shall make each payment to the Agent in
Dollars in immediately available funds as directed by the Agent. The Agent and each Bank is hereby
authorized at any time following any demand for payment hereunder to set off and apply any
indebtedness owed by the Agent or the Bank to the Guarantors against any and all of the Guaranteed
Obligations. The Agent and each Bank severally agrees to promptly notify the Guarantors after any
such setoff and application, but the failure to give such notice shall not affect the validity of
such setoff and application.

 

 

     Section 1.2. This Agreement shall continue to be effective or be reinstated, as the case may
be, if any payment on the Guaranteed Obligations must be refunded for any reason including any
bankruptcy proceeding. In the event that the Agent or any Bank must refund any payment received
against the Guaranteed Obligations, any prior release from the terms of this Agreement given to the
Guarantors by the Agent shall be without effect, and this Agreement shall be reinstated in full
force and effect. It is the intention of each Guarantor that the Guarantor’s obligations hereunder
shall not be discharged except by final payment of the Guaranteed Obligations.

     ARTICLE II Guaranty Absolute.

     Section 2.1. In the event that one or more other parties guarantees all or part of the
Guaranteed Obligations, such other guarantees shall not reduce any Guarantor’s obligations
hereunder and the Guarantor shall remain fully liable for all of the Guaranteed Obligations.

     Section 2.2. There are no conditions precedent to the enforcement of this Agreement, except as
expressly contained herein. It shall not be necessary for the Agent, in order to enforce payment
by any Guarantor under this Agreement, to show proof of any default by the Borrower, to exhaust the
Agent’s remedies against the Borrower or any other person liable for the payment of the Guaranteed
Obligations, to enforce any support for the payment of the Guaranteed Obligations, or to enforce
any other means of obtaining payment of the Guaranteed Obligations. Each Guarantor waives any
rights under Chapter 34 of the Texas Business and Commerce Code related to the foregoing. Neither
the Agent nor the Banks shall be required to mitigate damages or take any other action to reduce,
collect, or enforce the Guaranteed Obligations.

     Section 2.3. Each Guarantor agrees that such Guarantor’s obligations under this Agreement
shall not be released, diminished, or impaired by, and waives any rights which such Guarantor might
otherwise have which relate to:

          (a) Any lack of validity or enforceability of the Guaranteed Obligations, any Credit Document,
or any other agreement or instrument relating thereto;

          (b) Any increase, reduction, extension, or rearrangement of the Guaranteed Obligations, any
amendment, supplement, or other modification of the Credit Documents, or any waiver or consent
granted under the Credit Documents, including waivers of the payment and performance of the
Guaranteed Obligations;

          (c) Any release, exchange, subordination, waste, or other impairment of any collateral
securing payment of the Guaranteed Obligations;

          (d) Any full or partial release of the Borrower, any guarantor, or any other person liable for
the payment of the Guaranteed Obligations;

          (e) Any change in the organization or structure of the Borrower, any guarantor, or any other
person liable for the payment of the Guaranteed Obligations; or the insolvency, bankruptcy,
liquidation, or dissolution of the Borrower or any other person liable for the payment of the
Guaranteed Obligations;

-2-

 

          (f) The failure to apply or any manner of applying payments or the proceeds of any collateral
against the Guaranteed Obligations;

          (g) The failure to give notice of the occurrence of any of the events or actions referred to
in this Section 2.3, notice of any default or event of default, however denominated, under
the Credit Documents, notice of intent to demand, notice of demand, notice of presentment for
payment, notice of nonpayment, notice of intent to protest, notice of protest, notice of grace,
notice of dishonor, notice of intent to accelerate, notice of acceleration, notice of bringing of
suit, notice of sale or foreclosure of any collateral for the Guaranteed Obligations, notice of the
Agent’s or any Banks’ transfer of the Guaranteed Obligations, notice of the financial condition of
or other circumstances regarding the Borrower or any other person liable for the Guaranteed
Obligations, or any other notice of any kind relating to the Guaranteed Obligations (and the
parties intend that no Guarantor shall be considered a “Debtor” as defined in Section 9.102(28) of
the Texas Business and Commerce Code for the purpose of notices required to be given to a Debtor
thereunder, should such section apply); and

          (h) Any other action taken or omitted which affects the Guaranteed Obligations, whether or not
such action or omission prejudices any Guarantor or increases the likelihood that any Guarantor
will be required to pay the Guaranteed Obligations pursuant to the terms hereof—it is the
unambiguous and unequivocal intention of each Guarantor that such Guarantor shall be obligated to
pay the Guaranteed Obligations when due, notwithstanding any occurrence, circumstance, event,
action, or omission whatsoever, whether contemplated or uncontemplated, and whether or not
particularly described herein.

     ARTICLE III Subrogation. Until the payment in full in cash of the Guaranteed
Obligations, the termination of all Commitments, and the payment in full in cash or termination of
all Letter of Credit Obligations, no Guarantor shall take action pursuant to any rights which it
may acquire against the Borrower or any other person liable for the payment of the Guaranteed
Obligations under this Agreement, including any right of subrogation (including any statutory
rights of subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C. § 509, or under Chapter
34 of the Texas Business and Commerce Code), contribution, indemnification, reimbursement,
exoneration, or any right to participate in any claim or remedy of the Agent or the Banks against
the Borrower or any collateral, if any, which the Agent or the Banks now have or acquire. If any
amount shall be paid to any Guarantor in violation of the preceding sentence, such amount shall be
held in trust for the benefit of the Banks and immediately turned over to the Agent, for the
ratable benefit of the Banks, with any necessary endorsement to be applied to the Guaranteed
Obligations.

     ARTICLE IV Representations, Warranties, and Covenants of Guarantor. Each Guarantor
represents and warrants to (and with each extension of credit under the Credit Agreement again
represents and warrants to) and agrees with the Agent as follows:

     Section 4.1. Each Guarantor is familiar with, and has independently reviewed books and records
regarding, the financial condition of the Borrower, the other Guarantors, and any other persons
liable for the payment of the Guaranteed Obligations. As of the date hereof, assuming each of the
transactions contemplated by the Credit Documents is consummated and the Borrower makes full use of
the credit facilities thereunder, and taking into account the effect

-3-

 

thereof, the present realizable fair market value of the assets of each Guarantor exceeds the
total obligations of such Guarantor, specifically including the contingent obligations represented
by the fairly discounted value of such Guarantor’s obligations under this Agreement and the other
Credit Documents, taking into account the rights which such Guarantor would gain if payments under
this Agreement were made by such Guarantor. Each Guarantor is able to realize upon its assets and
pay its obligations as such obligations mature in the normal course of business. In consummating
the transactions contemplated by the Credit Documents, no Guarantor intends to disturb, delay,
hinder, or defraud either present or future creditors of the Guarantors.

     Section 4.2. The representations and warranties set forth in Article IV of the Credit
Agreement are incorporated herein by reference, and each Guarantor represents and warrants to the
Agent each such representation and warranty which applies to such Guarantor as if set forth herein.

     Section 4.3. The covenants set forth in Article V and VI of the Credit Agreement are
incorporated herein by reference, and each Guarantor agrees with the Agent to comply with each such
covenant which applies to such Guarantor as if set forth herein.

     ARTICLE V Miscellaneous.

     Section 5.1. Each Guarantor agrees to pay on demand (a) all reasonable out-of-pocket costs and
expenses of the Agent in connection with the preparation, execution, delivery, administration,
modification, and amendment of this Agreement including, without limitation, the reasonable fees
and out-of-pocket expenses of counsel for the Agent with respect to advising the Agent as to its
rights and responsibilities under this Agreement, and (b) all out-of-pocket costs and expenses, if
any, of the Agent, the Issuing Bank, and each Bank (including, without limitation, reasonable
counsel fees and expenses of the Agent, the Issuing Bank, and each Bank) in connection with the
enforcement (whether through negotiations, legal proceedings, or otherwise) of this Agreement.

     Section 5.2. EACH GUARANTOR SHALL INDEMNIFY AND HOLD HARMLESS EACH AGENT-RELATED PERSON, EACH
BANK AND THEIR RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, COUNSEL, AGENTS AND
ATTORNEYS-IN-FACT (COLLECTIVELY THE “INDEMNITEES”) FROM AND AGAINST ANY AND ALL
LIABILITIES, OBLIGATIONS, GUARANTEED OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, CLAIMS, DEMANDS,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, AND DISBURSEMENTS (INCLUDING ALL FEES, EXPENSES, AND
DISBURSEMENTS OF ANY LAW FIRM OR OTHER EXTERNAL COUNSEL AND, WITHOUT DUPLICATION, THE ALLOCATED

INCLUDING SETTLEMENT COSTS) OF ANY KIND OR NATURE WHATSOEVER, (EXCLUDING, HOWEVER, THE COSTS AND
EXPENSES INCURRED BY THE BANKS, OTHER THAN THE AGENT, IN CONNECTION WITH THE PREPARATION, EXECUTION
OR DELIVERY OF THIS AGREEMENT) WHICH MAY AT ANY TIME BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST
ANY SUCH INDEMNITEE IN ANY WAY RELATING TO OR ARISING OUT OF OR IN CONNECTION WITH (A) THE
EXECUTION, DELIVERY, ENFORCEMENT, PERFORMANCE OR ADMINISTRATION OF ANY

-4-

 

CREDIT DOCUMENT OR ANY OTHER AGREEMENT, LETTER, OR INSTRUMENT DELIVERED IN CONNECTION WITH THE
TRANSACTIONS CONTEMPLATED THEREBY OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED THEREBY, (B)

(INCLUDING ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT
IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF
SUCH LETTER OF CREDIT), OR (C) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS WASTE OR
HAZARDOUS SUBSTANCES ON OR FROM ANY PROPERTY CURRENTLY OR FORMERLY OWNED OR OPERATED BY THE
BORROWER OR ANY OF ITS SUBSIDIARIES, OR ANY LIABILITY UNDER ENVIRONMENTAL LAW RELATED IN ANY WAY TO
THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (D) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION,
INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER THEORY (INCLUDING ANY INVESTIGATION OF, PREPARATION FOR, OR DEFENSE OF ANY PENDING OR
THREATENED CLAIM, INVESTIGATION, LITIGATION OR PROCEEDING) AND REGARDLESS OF WHETHER ANY INDEMNITEE
IS A PARTY THERETO (ALL THE FOREGOING, COLLECTIVELY, THE “INDEMNIFIED LIABILITIES”), IN ALL
CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE,
CONTRIBUTORY, OR SOLE NEGLIGENCE OF THE INDEMNITEE; PROVIDED THAT SUCH INDEMNITY SHALL NOT,

OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, CLAIMS, DEMANDS, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES OR DISBURSEMENTS ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND

remaining provisions shall remain in full force and effect. All representations, warranties, and
covenants of each Guarantor in this Agreement shall survive the execution of this Agreement

-5-

 

and any other contract or agreement. If a due date for an amount payable is not specified in
this Agreement, the due date shall be the date on which the Agent demands payment therefor. The
Agent’s remedies under this Agreement shall be cumulative, and no delay in enforcing this Agreement
shall act as a waiver of the Agent’s or the Banks’ rights hereunder. The provisions of this
Agreement may be waived or amended only in a writing signed by the party against whom enforcement
is sought. This Agreement shall bind each Guarantor and its successors and assigns and shall inure
to the benefit of the Agent and its successors and assigns. No Guarantor may assign its rights or

FORM OF NOTE

			
	$[                    ]
	 	[date]

     For value received, the undersigned Stone Energy Corporation, a Delaware corporation
(“Borrower”), hereby promises to pay to [                               ] (“Bank”) or
registered assigns the principal amount of [ ] and [ ]/100 Dollars ($[                          ]) or, if
less, the aggregate outstanding principal amount of each Advance (as defined in the Credit
Agreement referred to below) made by the Bank to the Borrower, together with accrued but unpaid
interest on the principal amount of each such Advance from the date of such Advance until such
principal amount is paid in full, at such interest rates, and at such times, as are specified in
the Credit Agreement.

     This Note (“Note”) is one of the Notes referred to in, and is entitled to the benefits
of, and is subject to the terms of, the Second Amended and Restated Credit Agreement dated as of
August [___], 2008 (as the same may be modified from time to time, the “Credit Agreement”),
among the Borrower, the banks named therein (“Banks”), and Bank of America, N.A., as
administrative agent for the Banks (“Agent”). Capitalized terms used herein but not
defined herein shall have the meanings specified by the Credit Agreement. The Credit Agreement,
among other things, (a) provides for the making of Advances by the Bank to the Borrower from time
to time in an aggregate outstanding amount not to exceed the amount of this Note, the indebtedness
of the Borrower resulting from each such Advance being evidenced by this Note, and (b) contains
provisions for acceleration of the maturity of this Note upon the happening of certain events
stated in the Credit Agreement and for prepayments of principal prior to the maturity of this Note
upon the terms and conditions specified in the Credit Agreement.

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

     It is contemplated that because of prepayments there may be times when no indebtedness is owed
under this Note. Notwithstanding such prepayments, this Note shall remain valid and shall be in
force as to Advances made pursuant to the Credit Agreement after such prepayments.

     It is the intention of the Bank and the Borrower to conform strictly to any applicable usury
laws. Accordingly, the terms of the Credit Agreement relating to the prevention of usury will be
strictly followed.

     This Note shall be governed by, and construed and enforced in accordance with, the laws of the
State of Texas.

EXISTING LITIGATION

	1.	 	Louisiana Franchise Tax Litigation
	 
	 	 	Cynthia Bridges, Secretary, Louisiana Department of Revenue versus Stone Energy Corporation,
Nos. 20046227, 20046228, 20056524, 15th Judicial District Court, Lafayette Parish,
Louisiana.
	 
	 	 	On December 30, 2004, Stone was served with two petitions filed by the Louisiana Department
of Revenue (“LDR”) in the 15th Judicial District Court (Parish of Lafayette, Louisiana)
claiming additional franchise taxes due. In one case, the LDR is seeking additional franchise
taxes from Stone in the amount of $640,000, plus accrued interest of $352,000 (calculated
through December 15, 2004), for the franchise year 2001. In the other case, the LDR is
seeking additional franchise taxes from Stone (as successor to Basin Exploration, Inc.) in
the amount of $274,000, plus accrued interest of $159,000 (calculated through December 15,
2004), for the franchise years 1999, 2000 and 2001. Further, on December 29, 2005, the LDR
filed another petition in the 15th Judicial District Court claiming additional franchise
taxes due for the taxable years ended December 31, 2002 and 2003 in the amount of $2.6
million plus accrued interest calculated through December 15, 2005 in the amount of $1.2
million. Also, on January 2, 2008, Stone was served with a petition (civil action number
2007-6754) claiming $1.5 million of additional franchise taxes due for the 2004 franchise
year, plus accrued interest of $800,000 calculated through November 30, 2007. These
assessments all relate to the LDR’s assertion that sales of crude oil and natural gas from
properties located on the Outer Continental Shelf, which are transported through the state of
Louisiana, should be sourced to the state of Louisiana for purposes of computing the
Louisiana franchise tax apportionment ratio.
	 
	2.	 	Securities Litigation
	 
	 	 	Total coverage in the amount of $50,000,000 is available for the aggregate liability related
to the securities litigation matters listed below.

	 	(a)	 	In re: Stone Energy Corporation Securities Litigation, Docket No. 05-cv-02088,
United States District Court for the Western District of Louisiana, Lafayette Division.
	 
	 	 	 	The complaint alleges that the defendants, among other things, misstated or failed to
disclose (i) that Stone had materially overstated the Company’s financial results by
overvaluing its oil reserves through improper and aggressive reserve methodologies, (ii)
that Stone lacked adequate internal controls and was therefore unable to ascertain its
true financial condition, and (iii) that as a result of the foregoing, the values of
Stone’s proven reserves, assets and future net cash flows were materially overstated at
all relevant times.
	 
	 	(b)	 	In re Stone Energy Corporation Shareholder Derivative Litigation, Docket No.
05-CV-2166, United States District Court for the Western District of Louisiana,
Lafayette Division.

 

 

	 	 	 	This action was brought derivatively on behalf of Stone Energy Corporation against
certain current and former officers and directors and Stone Energy Corporation named as a
nominal defendant. This case involves the same issues as those in the litigation above.
	 
	 	(c)	 	Gregory Sakhno, derivatively on behalf of Stone Energy Corporation, versus James
H. Stone, et al. (including Stone’s directors, Kenneth H. Beer, D. Peter Canty and James
H. Prince), No. 20060505, 15th Judicial District Court, Lafayette Parish,
Louisiana.
	 
	 	 	 	This is a purported shareholder derivative action on behalf of Stone Energy Corporation,
with Stone Energy Corporation also named as a nominal defendant. The allegations in this
state court action are substantially the same as those in the federal shareholder
derivative action set forth above.

benefit of the Secured Parties, a security interest in all of such Debtor’s right, title, and
interest in and to the following property (the “Collateral”) to secure the payment and
performance of the Secured Obligations: (a) all Chattel Paper, all Collateral Accounts, all

products of or derived from the foregoing, and (c) all Proceeds of the foregoing.

To the extent that the Collateral is not subject to the UCC, each Debtor collaterally assigns all
of such Debtor’s right, title, and interest in and to such Collateral to the Agent for the benefit
of the Secured Parties to secure the payment and performance of the Secured Obligations to the full
extent that such a collateral assignment is possible under the relevant law.

Notwithstanding anything to the contrary in this Agreement, the term “Collateral” shall not include
(i) any lease, license, contract, property right or agreement (or any of its rights or interests
thereunder) if and to the extent that the grant of the security interest shall, after giving

-6-

 

effect to Sections 9.406, 9.407, 9.408 or 9.409 of the UCC (or any successor provision or
provisions) or any other applicable law, constitute or result in (A) the abandonment, invalidation
or unenforceability of any material right, title or interest of the applicable Debtor therein or
(B) a breach or termination pursuant to the terms of, or a default under, any such lease license,
contract, property rights or agreement; provided, however, that the security interest shall attach
immediately at any such time as the restriction resulting in abandonment, invalidation or
unenforceability or breach or termination shall be removed or become invalid or any condition
thereto (including any consent) shall be satisfied; (ii) once paid, any amounts constituting the
payment of a dividend or the repurchase or redemption of the shares of the Borrower’s common stock,
in each case to the extent such dividend, repurchase or redemption is permitted under Section
6.5 of the Credit Agreement; and (iii) Realty Collateral (as such term is defined in the

     2.2 Avoidance Limitation. Notwithstanding Section 2.1 above, the amount of
any Secured Obligations that are secured by any Debtor’s rights in Collateral subject to a Lien in
favor of the Agent hereunder or under any other Security Document shall be limited to the extent,
if any, required so that the Liens it has granted under this Security Agreement shall not be
subject to avoidance under Section 548 of the Bankruptcy Code of the United States or to being set
aside or annulled under any Legal Requirement relating to fraud on creditors. In determining the
limitations, if any, on the amount of any Secured Obligations that are subject to the Lien on such

parties hereto that any rights of subrogation or contribution which such Debtor may have under the

     2.3 Debtors Remain Liable. Anything herein to the contrary notwithstanding: (a) each
Debtor shall remain liable under the Contracts included in the Collateral to the extent set forth
therein to perform such Debtor’s obligations thereunder to the same extent as if this Agreement had
not been executed; (b) the exercise by the Agent of any rights hereunder shall not release any
Debtor from any obligations under the Contracts included in the Collateral; and (c) the Agent shall
not have any obligation under the Contracts included in the Collateral by reason of this Agreement,
nor shall the Agent be obligated to perform or fulfill any of the obligations of any Debtor
thereunder, including any obligation to make any inquiry as to the nature or sufficiency of any
payment any Debtor may be entitled to receive thereunder, to present or file any claim, or to take
any action to collect or enforce any claim for payment thereunder.

-7-

 

Secured Parties, pursuant to this Agreement or (ii) such as have been filed with respect to

thereof, such Debtor shall immediately notify the Agent thereof, and shall take any actions
requested by the Agent to enable the Agent to obtain “control” (within the meaning of Section 8-106

          (e) If such Debtor is an issuer of Pledged Securities, such Debtor agrees that (i) it will be
bound by the terms of this Agreement relating to the Pledged Securities issued by it and will
comply with such terms insofar as such terms are applicable to it and (ii) it will comply with
instructions received by it pursuant to the terms of Section 4.4(f) with respect to the
Pledged Securities issued by it.

          (f) Each Debtor hereby authorizes and instructs each issuer of any Pledged Securities pledged
by such Debtor hereunder to (i) comply with any instruction received by it from the Agent in
writing that (x) states that an Event of Default has occurred and is continuing and (y) is
otherwise in accordance with the terms of this Agreement, without any other or further instructions
from such Debtor, and each Debtor agrees that each such issuer shall be fully protected in so
complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other
payments with respect to the Pledged Securities directly to the Agent.

     4.5 Commercial Tort Claims. If any Debtor shall at any time hold or acquire a
commercial tort claim with a value in excess of $2,500,000, such Debtor shall promptly notify the
Agent in a writing signed by such Debtor of the brief details thereof and grant to the Agent in
such writing a security interest therein and in the proceeds thereof, all upon the terms of this
Security Agreement, with such writing to be in form and substance satisfactory to the Agent.
Notwithstanding the foregoing, any such security interest in commercial tort claims shall, prior to
the occurrence (and after the waiver or cure) of an Event of Default (and during the continuation
of an Event of Default unless the Agent has demanded the attachment of such

-12-

 

security interest thereto), not be required to attach to the extent the value of any such
commercial tort claim does not exceed $2,500,000.

SECTION 5.

LIMITATION ON PERFECTION OF SECURITY INTEREST

Notwithstanding anything to the contrary contained above, the perfection of the security interest
granted in Section 2 above (except with respect to Deposit Accounts, Letter of Credit
Rights and certificated Pledged Securities) will, prior to the occurrence (and after the waiver or
cure) of an Event of Default (and during the continuation of an Event of Default unless the Agent
has required that further actions are taken with respect to the perfection thereof), be effected
solely by filing an appropriate financing statement under the applicable Uniform Commercial Code.
The perfection of the security interest granted in Section 2 above in certificated Pledged
Securities will be effected by filing an appropriate financing statement under the applicable
Uniform Commercial Code and by possession by the Agent of the certificates representing such
Pledged Securities, accompanied by such instruments of transfer or assignment duly executed in
blank as the Agent may from time to time specify.

SECTION 6.

REMEDIAL PROVISIONS

During the existence of an Event of Default, the Agent may, at the Agent’s option, exercise one or
more of the remedies specified elsewhere in this Agreement or the following remedies:

     6.1 General Interim Remedies. During the existence of an Event of Default, the Agent
may exercise one or more of the following remedies:

          (a) To the extent permitted by law, the Agent may exercise all the rights and remedies of a
secured party under the UCC.

          (b) The Agent may prosecute actions in equity or at law for the specific performance of any
covenant or agreement herein contained or in aid of the execution of any power herein granted or
for the enforcement of any other appropriate legal or equitable remedy.

          (c) The Agent may require any Debtor to promptly assemble any tangible Collateral of such
Debtor and make it available to the Agent at a place to be designated by the Agent. The Agent may
occupy any premises owned or leased by any Debtor where the Collateral is assembled for a
reasonable period in order to effectuate the Agent’s rights and remedies hereunder or under law,
without obligation to any Debtor with respect to such occupation.

     6.2 Receivables, Chattel Paper, Instruments and Payment Intangibles. During the
existence of an Event of Default, the Agent may establish one or more Collateral Accounts for the
purpose of collecting the payments due to the Debtors under any Contracts or otherwise with respect
to the Receivables, Chattel Paper, Instruments and/or payment intangibles constituting Collateral
and holding the proceeds thereof, and may, or may direct the Debtors to, instruct all

-13-

 

makers and/or all obligors with respect thereto to make all payments with respect to such
Collateral directly to the Agent for deposit into the Collateral Accounts designated by the Agent.
After such direction to the Debtors, all payments, whether of principal, interest, or other
amounts, under any Contracts or otherwise with respect to the Receivables, Chattel Paper,
Instruments and/or payment intangibles constituting Collateral shall be directed to the appropriate
Collateral Account. All such payments which may from time to time come into the possession of any
Debtor shall be held in trust for the Agent, segregated from the other funds of such Debtor, and
delivered to the Agent immediately in the form received with any necessary endorsement for deposit
into the appropriate Collateral Account, such delivery in no event to be later than one Business
Day after receipt thereof by the applicable Debtor. Each Debtor agrees to execute any documents
reasonably requested by the Agent to create any Collateral Account and pledge it to the Agent. In
connection with the foregoing, the Agent shall have the right at any time during the existence of
an Event of Default to take any of the following actions, in the Agent’s own name or in the name of
the applicable Debtor: compromise or extend the time for payment of any payments due with respect
to any Instrument or Chattel Paper upon such terms as the Agent may reasonably determine; endorse
the name of the applicable Debtor, on checks, instruments, or other evidences of payment with
respect to any such Collateral; make written or verbal requests for verification of amount owing on
any such Collateral from the maker thereof or obligor thereunder; open mail addressed to such
Debtor which the Agent reasonably believes relates to any such Collateral, and, to the extent of
checks or other payments with respect to any such Collateral, dispose of the same in accordance
with this Agreement; take action in the Agent’s name or the applicable Debtor’s name, to enforce
collection of such checks and other payments; and take all other action necessary to carry out this
Agreement and give effect to the Agent’s rights hereunder. Costs and expenses incurred by the
Agent in collection and enforcement of amounts owed under any Contracts or otherwise with respect
to the Receivables, Chattel Paper, Instruments and/or payment intangibles constituting Collateral,
including attorneys’ fees and out-of-pocket expenses, shall be reimbursed by the applicable Debtor
to the Agent on demand.

     6.3 Contracts. During the existence of an Event of Default, the Agent may, at its
option, exercise one or more of the following remedies with respect to the Contracts that
constitute Collateral:

          (a) (i) take any action permitted under Section 6.2 and (ii) in the place and stead of
the applicable Debtor, exercise any other rights of such Debtor under such Contracts in accordance
with the terms thereof. Without limitation of the foregoing, each Debtor agrees that under the
foregoing circumstances, the Agent may give notices, consents and demands and make elections under
such Contracts, modify or waive the terms of such Contracts and enforce such Contracts, in each
case, to the same extent and on the same terms as such Debtor might have done. It is understood
and agreed that notwithstanding the exercise of such rights and/or the taking or such actions by
the Agent, such Debtor shall remain liable for performance of its obligations under such Contracts;

          (b) upon receipt by the Agent of notice from any counterparty to any such Contract of such
Person’s intent to terminate such Contract, the Agent shall be entitled to (i) cure or cause to be
cured the condition giving rise to such Person’s right of termination of such

-14-

 

Contract, or (ii) acquire and assume (or assign and cause the assumption by a third party of)
the rights and obligations of the applicable Debtor under such Contract; and

          (c) upon termination of any Contract by operation of law or otherwise, the Agent shall be
entitled to enter into a new agreement (“Successor Agreement”) with the counterparty to
such terminated Contract, on the same terms and with the same provisions as such terminated
Contract. Each Debtor agrees that such Debtor shall have no rights whatsoever with respect to any
Successor Agreement.

     6.4 Pledged Securities.

          (a) Each Debtor recognizes that the Agent may be unable to effect a public sale of any or all
the Pledged Securities, by reason of certain prohibitions and registration requirements contained
in the Securities Act and applicable state securities laws or otherwise, and may be compelled to
resort to one or more private sales thereof to a restricted group of purchasers which will be
obliged to agree, among other things, to acquire such securities for their own account for
investment and not with a view to the distribution or resale thereof. Each Debtor acknowledges and
agrees that any such private sale may result in prices and other terms less favorable than if such
sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The Agent shall be under no
obligation to delay a sale of any of the Pledged Securities for the period of time necessary to
permit the issuer thereof to register such securities for public sale under the Securities Act, or
under applicable state securities laws, even if such issuer would agree to do so.

          (b) Each Debtor agrees to use its best efforts to do or cause to be done all such other acts
(other than preparation and filing of a registration statement) as may be necessary to make such
sale or sales of all or any portion of the Pledged Securities pursuant to this Section 6.4
valid and binding and in compliance with any and all other applicable Legal Requirements. Each
Debtor further agrees that a breach of any of the covenants contained in this Section 6.4
will cause irreparable injury to the Agent and the Secured Parties, that the Agent and the Secured
Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each
and every covenant contained in this Section 6.4 shall be specifically enforceable against
such Debtor, and such Debtor hereby waives and agrees not to assert any defenses against an action
for specific performance of such covenants except for a defense that no Event of Default has
occurred.

     6.5 Foreclosure.

          (a) During the existence of an Event of Default, the Agent may foreclose on the Collateral in
any manner permitted by the courts of or in the State of Texas or the jurisdiction in which any
Collateral is located. If the Agent should institute a suit against any Collateral or any Debtor
for the collection of the Secured Obligations and for the foreclosure of this Agreement, the Agent
may at any time before the entry of a final judgment dismiss the same, and take any other action
permitted by this Agreement.

-15-

 

          (b) To the extent permitted by law, the Agent may exercise all the foreclosure rights and
remedies of a secured party under the UCC during the existence of an Event of Default. In
connection therewith, the Agent may sell any Collateral at public or private sale, at the office of
the Agent or elsewhere, for cash or credit and upon such other terms as the Agent deems
commercially reasonable. The Agent may sell any Collateral at one or more sales, and the security
interest granted hereunder shall remain in effect as to the unsold portion of the Collateral. Each
Debtor agrees that to the extent permitted by law such sales may be made without notice. If notice
is required by law, each Debtor hereby deems ten days advance notice of the time and place of any
public or private sale reasonable notification, recognizing that if any portion of the Collateral
is perishable or threatens to decline speedily in value or is of a type customarily sold on a
recognized market, shorter notice may be reasonable. The Agent shall not be obligated to make any
sale of Collateral regardless of notice of sale having been given. The Agent may adjourn any sale
by announcement at the time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was adjourned. In the event that any sale hereunder is not
completed or is defective in the opinion of the Agent, the Agent shall have the right to cause
subsequent sales to be made hereunder. Any statements of fact or other recitals made in any bill
of sale, assignment, or other document representing any sale hereunder, including statements
relating to the occurrence of an Event of Default, acceleration of the Secured Obligations, notice
of the sale, the time, place, and terms of the sale, and other actions taken by the Agent in
relation to the sale may be conclusively relied upon by the purchaser at any sale hereunder. The
Agent may delegate to any agent the performance of any acts in connection with any sale hereunder,
including the sending of notices and the conduct of the sale.

     6.6 Application of Proceeds. Unless otherwise specified herein, any cash proceeds
received by the Agent from the sale of, collection of, or other realization upon any part of the
Collateral or any other amounts received by the Agent hereunder may be, at the reasonable
discretion of the Agent (i) held by the Agent in one or more Cash Collateral Accounts as cash
collateral for the Secured Obligations or (ii) applied in the order specified in Section
7.7 of the Credit Agreement.

     6.7 Waiver of Certain Rights. To the full extent each Debtor may do so under
applicable law, such Debtor shall not insist upon, plead, claim, or take advantage of any law
providing for any appraisement, valuation, stay, extension, or redemption, and such Debtor hereby
waives and releases the same, and all rights to a marshaling of the assets of such Debtor,
including the Collateral of such Debtor, or to a sale in inverse order of alienation in the event
of foreclosure of the liens and security interests hereby created. Such Debtor shall not assert
any right under any law pertaining to the marshaling of assets, sale in inverse order of
alienation, the administration of estates of decedents or other right to defeat, reduce, or
otherwise adversely affect in any respect the rights of the Agent under the terms of this
Agreement.

     6.8 Remedies Cumulative. The Agent’s remedies under this Agreement and the Credit
Documents to which any Debtor is a party shall be cumulative, and no delay in enforcing this
Agreement and the Credit Documents to which any Debtor is a party shall act as a waiver of the
Agent’s rights hereunder.

-16-

 

     6.9 Reinstatement. The obligations of each Debtor under this Agreement shall continue
to be effective or automatically be reinstated, as the case may be, if at any time payment of any
of the Secured Obligations is rescinded or otherwise must be restored or returned by the Agent upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Debtor or any other
obligor or otherwise, all as though such payment had not been made.

SECTION 7.

MISCELLANEOUS

     7.1 Amendments. None of the terms or provisions of this Agreement may be waived,
amended, supplemented or otherwise modified except in accordance with Section 9.1 of the
Credit Agreement. No consent of any holder of Secured Obligations arising under a Specified Swap
Contract (except in such Person’s capacity as a Bank, if applicable) shall be required for any
waiver, amendment, supplement or other modification to this Agreement.

     7.2 Notices. All notices, requests and demands to or upon the Agent or any Debtor
hereunder shall be effected in the manner provided for in Section 9.2 of the Credit
Agreement. All notices, requests and demands hereunder to any Debtor shall be given to it at its
address or telecopy number provided on Schedule 7.2 or at such other address in the United
States as may be specified by such Debtor in a written notice delivered to the Agent in accordance
with Section 9.2 of the Credit Agreement.

     7.3 No Waiver by Course of Conduct; Cumulative Remedies; No Duty. No failure to
exercise, nor any delay in exercising, on the part of the Agent, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or
privilege hereunder shall preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. A waiver by the Agent of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy that the Agent would otherwise have
on any future occasion. The rights and remedies provided herein and in the other Credit Documents
are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights
or remedies provided by law. The powers conferred on Agent under this Agreement are solely to
protect Agent’s rights under this Agreement and shall not impose any duty upon it to exercise any
such powers. Except as elsewhere provided hereunder, Agent shall have no duty as to any of the
Collateral or as to the taking of any necessary steps to preserve rights against prior parties or
any other rights pertaining to the Collateral.

     7.4 Enforcement Expenses; Indemnification.

          (a) Costs and Expenses. Each Debtor shall pay (i) all out-of-pocket expenses of
Agent, including reasonable fees and disbursements of special counsel for Agent, in connection with
the preparation of this Agreement and the other Credit Documents and, if appropriate, the
recordation of the Credit Documents, any waiver or consent hereunder or any amendment hereof or any
Default or alleged Default hereunder, and (ii) if an Event of Default occurs, all out-of-pocket
expenses incurred by Agent and each Bank, including fees and disbursements of counsel in connection
with such Event of Default and collection and other enforcement proceedings resulting therefrom,
fees of auditors and consultants incurred in

-17-

 

connection therewith and investigation expenses incurred by Agent and each Bank in connection
therewith. Borrower shall indemnify each Bank against any Taxes imposed by reason of the execution
and delivery of this Agreement or the Notes (other than Taxes in respect of the net income of such
Bank).

          (b) Indemnification. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE
CONSUMMATED, THE BORROWER SHALL INDEMNIFY AND HOLD HARMLESS EACH AGENT-RELATED PERSON, EACH BANK
AND THEIR RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES, COUNSEL, AGENTS AND
ATTORNEYS-IN-FACT (COLLECTIVELY THE “INDEMNITEES”) FROM AND AGAINST ANY AND ALL

OR OTHER EXTERNAL COUNSEL AND, WITHOUT DUPLICATION, THE ALLOCATED COST OF INTERNAL LEGAL SERVICES
AND ALL EXPENSES AND DISBURSEMENTS OF INTERNAL COUNSEL AND INCLUDING SETTLEMENT COSTS) OF ANY KIND
OR NATURE WHATSOEVER, (EXCLUDING, HOWEVER, THE COSTS AND EXPENSES INCURRED BY THE BANKS, OTHER THAN
THE AGENT, IN CONNECTION WITH THE PREPARATION, EXECUTION OR DELIVERY OF THIS AGREEMENT) WHICH MAY
AT ANY TIME BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST ANY SUCH INDEMNITEE IN ANY WAY RELATING
TO OR ARISING OUT OF OR IN CONNECTION WITH (A) THE EXECUTION, DELIVERY, ENFORCEMENT, PERFORMANCE OR
ADMINISTRATION OF ANY CREDIT DOCUMENT OR ANY OTHER AGREEMENT, LETTER, OR INSTRUMENT DELIVERED IN
CONNECTION WITH THE TRANSACTIONS CONTEMPLATED THEREBY OR THE CONSUMMATION OF THE TRANSACTIONS
CONTEMPLATED THEREBY, (B) ANY COMMITMENT, ADVANCE, OR LETTER OF CREDIT OR THE USE OR PROPOSED USE
OF THE PROCEEDS THEREFROM (INCLUDING ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT
UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY
COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT), OR (C) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE
OF HAZARDOUS WASTE OR HAZARDOUS SUBSTANCES ON OR FROM ANY PROPERTY CURRENTLY OR FORMERLY OWNED OR
OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR ANY LIABILITY UNDER ENVIRONMENTAL LAW
RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (D) ANY ACTUAL OR PROSPECTIVE
CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY (INCLUDING ANY INVESTIGATION OF, PREPARATION FOR, OR DEFENSE OF
ANY PENDING OR THREATENED CLAIM, INVESTIGATION, LITIGATION OR PROCEEDING) AND REGARDLESS OF WHETHER
ANY INDEMNITEE IS A PARTY THERETO (ALL THE FOREGOING, COLLECTIVELY, THE “INDEMNIFIED
LIABILITIES”), IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF
THE COMPARATIVE, CONTRIBUTORY, OR SOLE NEGLIGENCE OF THE INDEMNITEE; PROVIDED THAT SUCH
INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH

-18-

 

LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, CLAIMS, DEMANDS, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES OR DISBURSEMENTS ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY
FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT

OF ANY INFORMATION OR OTHER MATERIALS OBTAINED THROUGH INTRALINKS OR OTHER SIMILAR INFORMATION
TRANSMISSION SYSTEMS IN CONNECTION WITH THIS AGREEMENT, NOR SHALL ANY INDEMNITEE HAVE ANY LIABILITY

OR ARISING OUT OF ITS ACTIVITIES IN CONNECTION HEREWITH OR THEREWITH (WHETHER BEFORE OR AFTER THE
EFFECTIVE DATE). ALL AMOUNTS DUE UNDER THIS SECTION 7.4 SHALL BE PAYABLE WITHIN TEN
BUSINESS DAYS AFTER DEMAND THEREFOR. THE AGREEMENTS IN THIS SECTION SHALL SURVIVE THE RESIGNATION
OF THE AGENT, THE REPLACEMENT OF ANY BANK, THE TERMINATION OF THIS AGREEMENT, THE REPAYMENT,
SATISFACTION OR DISCHARGE OF ALL THE OTHER SECURED OBLIGATIONS AND THE RELEASE OF THE COLLATERAL.

     7.5 Successors and Assigns. This Agreement shall be binding upon the successors and
assigns of each Debtor and shall inure to the benefit of the Agent and the Secured Parties and
their successors and assigns; provided that no Debtor may assign, transfer or delegate any
of its rights or obligations under this Agreement without the prior written consent of the Agent.

     7.6 Set-Off. Each Debtor hereby irrevocably authorizes the Agent and each Bank at any
time and from time to time upon the occurrence and during the continuation of any Event of Default,
without prior notice to such Debtor or any other Debtor, any such notice being waived by such
Debtor 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 Bank to or for the credit or the account of the respective Debtor against
any and all Obligations owing to such Bank under the Credit Agreement, the Guaranties, or under any
other Credit Document, now or hereafter existing, irrespective of whether or not the Agent or such
Bank shall have made demand for payment and although such Obligations may be contingent or
unmatured or denominated in a currency different from that of the applicable deposit or
indebtedness. Any such set-off shall be subject to the notice requirements of Section 7.4
of the Credit Agreement; provided, however, that the failure to give such notice
shall not affect the validity of such set-off and application.

     7.7 Counterparts. This Agreement may be executed in one or more counterparts (and by
different parties hereto in different counterparts), each of which shall constitute an original,
but all of which together shall constitute a single contract. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy or electronic transmission shall be effective as
delivery of an original manually executed counterpart of this Agreement.

     7.8 Severability. If any provision of this Agreement is held to be illegal, invalid
or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this
Agreement shall not be affected or impaired thereby and (b) the parties shall endeavor in good

-19-

 

faith negotiations to replace the illegal, invalid or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to that of the illegal, invalid
or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

     7.9 Section Headings. The Section headings used in this Agreement are included for
convenience of reference only and shall not affect the interpretation of this Agreement.

     7.10 Integration; Direct Conflict. This Agreement and the other Credit Documents
constitute the entire contract among the parties relating to the subject matter hereof and
supersede any and all previous agreements and understandings, oral or written, relating to the
subject matter hereof. In the event of a direct conflict between this Agreement and the Credit
Agreement, the Credit Agreement shall control; provided, however, the parties understand and agree
that this Agreement sets forth additional covenants, obligations and rights and the parties will
use all reasonable efforts to construe the provisions and covenants in this Agreement as not being
in direct conflict with the Credit Agreement.

     7.11 GOVERNING LAW, WAIVER OF JURY TRIAL, ETC.

          (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE

FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER
JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS
AGREEMENT OR IN ANY OTHER CREDIT DOCUMENT SHALL AFFECT ANY RIGHT THAT THE AGENT, ANY BANK OR THE
ISSUING BANK MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY
OTHER CREDIT DOCUMENT AGAINST ANY DEBTOR OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

          (c) WAIVER OF VENUE. EACH DEBTOR IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY ANY

LEGAL REQUIREMENT, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF

IN ANY COURT REFERRED TO IN PARAGRAPH (b) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN

MAXIMUM EXTENT NOT PROHIBITED BY LAW, (A) ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY

such Subsidiary of an instrument in the form of Annex I hereto.

     7.13 Termination; Releases.

          (a) This Security Agreement and the security interest created hereby shall terminate when all
the Secured Obligations have been indefeasibly paid in full and all commitments of each of the
Secured Parties to the Debtors have been fully and finally terminated, at which time the Agent
shall execute and deliver to the Debtors or the Debtors’ designee, at the Debtors’ expense, all
Uniform Commercial Code termination statements and similar documents which the Debtors shall
reasonably request from time to time to evidence such termination. Any execution and delivery of
termination statements or documents pursuant to this Section 7.13(a) shall be without
recourse to or warranty by the Agent.

          (b) Any Debtor other than the Borrower shall automatically be released from its obligations

accordance with the terms of the Credit Agreement; provided that, to the extent required by
the Credit Agreement, the Majority Banks or, if required by the terms of the Credit Agreement, such
other requisite number of Banks, shall have consented to such sale, transfer or other disposition
and the terms of such consent did not provide otherwise. If any of the Collateral shall be sold,
transferred or otherwise disposed of by any Debtor in a transaction permitted by the Credit
Agreement the security interest created hereby in any Collateral that is so sold, transferred or
otherwise disposed of shall automatically terminate and be released upon the closing of such sale,
transfer or other disposition, and such Collateral shall be sold free and clear of the Lien and
security interest created hereby; provided, however, that such security interest

Annex I to the

Security Agreement

     This SUPPLEMENT NO. [     ] dated as of [               ] (this
“Supplement”), is delivered in connection with the Security Agreement dated as of August [     ],
2008 (as amended or otherwise modified from time to time, the “Security Agreement”),
among Stone Energy Corporation (the “Borrower”), certain subsidiaries of the Borrower party
thereto from time to time (such subsidiaries together with the Borrower, the “Debtors”),
and Bank of America, N.A. (“BOA”), as administrative agent (in such capacity, the
“Agent”) for the benefit of the Secured Parties (as defined therein).

     A. Reference is made to the Second Amended and Restated Credit Agreement dated as
of August [     ], 2008 (as amended or otherwise modified from time to time, the “Credit Agreement”), among
the Borrower, the lenders from time to time party thereto (the “Banks”), and the Agent.

     B. The Debtors have entered into the Security Agreement as a condition precedent to the
effectiveness of the Credit Agreement. Section 7.12 of the Security Agreement provides
that additional Subsidiaries of the Borrower may become Debtors under the Security Agreement by
execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary
(the “New Debtor”) is executing this Supplement in accordance with the requirements of the
Credit Agreement to become a Debtor under the Security Agreement.

     C. Capitalized terms used herein and not otherwise defined herein shall have the meanings
assigned to such terms in the Security Agreement or, where any such term is not defined in the
Security Agreement, the Credit Agreement.

     Accordingly, the Agent and the New Debtor agree as follows:

     SECTION 1. In accordance with Section 7.12 of the Security Agreement, the New Debtor
by its signature below becomes a Debtor under the Security Agreement with the same force and effect
as if originally named therein as a Debtor, and the New Debtor hereby (a) agrees to all the terms
and provisions of the Security Agreement applicable to it as a Debtor thereunder and (b) represents
and warrants that the representations and warranties made by it as a Debtor thereunder are true and
correct on and as of the date hereof. The Schedules to the Security Agreement are hereby
supplemented by the Schedules attached hereto with respect to the New Debtor. In furtherance of
the foregoing, the New Debtor, as security for the payment and performance in full of the Secured
Obligations (as defined in the Security Agreement), does hereby create and grant to the Agent, for
the benefit of the Secured Parties, a security interest in and lien on all of the New Debtor’s
right, title and interest in and to the Collateral of the New Debtor. Each reference to a “Debtor”
in the Security Agreement shall be deemed to include the New Debtor.

     SECTION 2. The New Debtor represents and warrants to the Agent that this Supplement has been
duly authorized, executed and delivered by it and constitutes its legal, valid and binding
obligation, enforceable against it in accordance with its terms.

Annex I to Security Agreement

     SECTION 3. This Supplement may be executed by one or more of the parties to this Agreement on
any number of separate counterparts (including by telecopy), and all of said counterparts taken
together shall be deemed to constitute one and the same instrument.

     SECTION 4. Except as expressly supplemented hereby, the Security Agreement and the Guaranties
shall remain in full force and effect.

     SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND INTERPRETED AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF TEXAS.

     SECTION 6. All communications and notices to the New Debtor under the Security Agreement shall
be in writing and given as provided in Section 7.2 of the Security Agreement to the address
for the New Debtor set forth under its signature below.

     SECTION 7. The New Debtor agrees to reimburse the Agent for its reasonable out-of-pocket
expenses in connection with this Supplement, including the reasonable fees, other charges and
disbursements of counsel for the Agent.

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

THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.
