ARTICLE II.

THE COMMITMENTS AND CREDIT EXTENSIONS

     2.01 Committed Loans. Subject to the terms and conditions set forth herein, each Lender
severally agrees to make loans (each such loan, a “Committed Loan”) to the Borrower from
time to time, on any Business Day during the Availability Period, in an aggregate amount not to
exceed at any time outstanding the amount of such Lender’s Commitment; provided,
however, that after giving effect to any Committed Borrowing, (i) the Total Outstandings
shall not exceed the lesser of the Aggregate Commitments and the Borrowing Base, and (ii) the
aggregate Outstanding Amount of the Committed Loans of any Lender, plus such Lender’s
Applicable Percentage of the Outstanding Amount of all L/C Obligations, plus such Lender’s
Applicable Percentage of the Outstanding Amount of all Swing Line Loans shall not exceed such
Lender’s Commitment. Within the limits of each Lender’s Commitment, and subject to the other terms
and conditions hereof, the Borrower may borrow under this Section 2.01, prepay under
Section 2.06, and reborrow under this Section 2.01. Committed Loans may be Base
Rate Loans or Eurodollar Rate Loans, as further provided herein.

     2.02 Borrowings, Conversions and Continuations of Committed Loans.

     (a) Each Committed Borrowing, each conversion of Committed Loans from one Type to the other,
and each continuation of Eurodollar Rate Loans shall be made upon the Borrower’s irrevocable notice
to the Administrative Agent, which may be given by telephone. Each such notice must be received by
the Administrative Agent not later than 11:00 a.m. (i) three Business Days prior to the requested
date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans or of any
conversion of Eurodollar Rate Loans to Base Rate Committed Loans, and (ii) on the requested date of
any Borrowing of Base Rate Committed Loans. Each telephonic notice by the Borrower pursuant to
this Section 2.02(a) must be confirmed promptly by delivery to the Administrative Agent of
a written Committed Loan Notice, appropriately completed and signed by a Responsible Officer of the
Borrower. Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall be in a
principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Except as
provided in Sections 2.03(c), each
Borrowing of or conversion to Base Rate Committed Loans shall be in a principal amount of
$500,000 or a whole multiple of $100,000 in excess thereof. Each Committed Loan Notice (whether
telephonic or written) shall specify (i) whether the Borrower is requesting a Committed Borrowing,
a conversion of Committed Loans from one Type to the other, or a continuation of Eurodollar Rate
Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be
(which shall be a Business Day), (iii) the principal amount of Committed Loans to be borrowed,
converted or continued, (iv) the Type of Committed Loans to be borrowed or to which existing
Committed Loans are to be converted, and (v) if applicable, the duration of the Interest Period
with respect thereto. If the Borrower fails to specify a Type of Committed Loan in a Committed
Loan Notice or if the Borrower fails to give a timely notice requesting a

29

 

conversion or
continuation, then the applicable Committed Loans shall be made as, or converted to, Base Rate
Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of
the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If the
Borrower requests a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans in any
such Committed Loan Notice, but fails to specify an Interest Period, it will be deemed to have
specified an Interest Period of one month.

     (b) Following receipt of a Committed Loan Notice, the Administrative Agent shall promptly
notify each Lender of the amount of its Applicable Percentage of the applicable Committed Loans,
and if no timely notice of a conversion or continuation is provided by the Borrower, the
Administrative Agent shall notify each Lender of the details of any automatic conversion to Base
Rate Loans described in the preceding subsection. In the case of a Committed Borrowing, each
Lender shall make the amount of its Committed Loan available to the Administrative Agent in
immediately available funds at the Administrative Agent’s Office not later than 1:00 p.m. on the
Business Day specified in the applicable Committed Loan Notice. Upon satisfaction of the
applicable conditions set forth in Section 4.02 (and, if such Borrowing is the initial
Credit Extension, Section 4.01), the Administrative Agent shall make all funds so received
available to the Borrower in like funds as received by the Administrative Agent either by (i)
crediting the account of the Borrower on the books of Bank of America with the amount of such funds
or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and
reasonably acceptable to) the Administrative Agent by the Borrower; provided,
however, that if, on the date the Committed Loan Notice with respect to such Borrowing is
given by the Borrower, there are L/C Borrowings outstanding, then the proceeds of such Borrowing,
first, shall be applied to the payment in full of any such L/C Borrowings, and
second, shall be made available to the Borrower as provided above.

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

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

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

     2.03 Letters of Credit.

     (a) The Letter of Credit Commitment.

     (i) Subject to the terms and conditions set forth herein, (A) the L/C Issuer agrees, in
reliance upon the agreements of the Lenders set forth in this Section 2.03, (1)

30

 

from
time to time on any Business Day during the period from the Closing Date until the Letter of
Credit Expiration Date, to issue Letters of Credit for the account of the Borrower, and to
amend or extend Letters of Credit previously issued by it, in accordance with subsection (b)
below, and (2) to honor drawings under the Letters of Credit; and (B) the Lenders severally
agree to participate in Letters of Credit issued for the account of the Borrower and any
drawings thereunder; provided that after giving effect to any L/C Credit Extension
with respect to any Letter of Credit, (x) the Total Outstandings shall not exceed the lesser
of the Aggregate Commitments and the Borrowing Base, (y) the aggregate Outstanding Amount of
the Committed Loans of any Lender, plus such Lender’s Applicable Percentage of the
Outstanding Amount of all L/C Obligations, plus such Lender’s Applicable Percentage
of the Outstanding Amount of all Swing Line Loans shall not exceed such Lender’s Commitment,
and (z) the Outstanding Amount of the L/C Obligations shall not exceed the Letter of Credit
Sublimit. Each request by the Borrower for the issuance or amendment of a Letter of Credit
shall be deemed to be a representation by the Borrower that the L/C Credit Extension so
requested complies with the conditions set forth in the proviso to the preceding sentence.
Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s
ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower
may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that
have expired or that have been drawn upon and reimbursed. All Existing Letters of Credit
shall be deemed to have been issued pursuant hereto, and from and after the Closing Date
shall be subject to and governed by the terms and conditions hereof.

     (ii) The L/C Issuer shall not issue any Letter of Credit, if:

     (A) subject to Section 2.03(b)(iii), the expiry date of such requested Letter
of Credit would occur more than twelve months after the date of issuance or last
extension, unless the Required Lenders have approved such expiry date; or

     (B) the expiry date of such requested Letter of Credit would occur after the
Letter of Credit Expiration Date, unless all the Lenders have approved such expiry
date.

     (iii) The L/C Issuer 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 L/C Issuer from
issuing such Letter of Credit, or any Law applicable to the L/C Issuer or any
request or directive (whether or not having the force of law) from any Governmental
Authority with jurisdiction over the L/C Issuer shall prohibit, or request that the
L/C Issuer refrain from, the issuance of letters of credit generally or such Letter
of Credit in particular or shall impose upon the L/C Issuer with respect to such
Letter of Credit any restriction, reserve or capital requirement (for which the L/C
Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or
shall impose upon the L/C Issuer any unreimbursed loss, cost or

31

 

expense which was
not applicable on the Closing Date and which the L/C Issuer in good faith deems
material to it;

     (B) the issuance of such Letter of Credit would violate one or more policies of
the L/C Issuer applicable to letters of credit generally;

     (C) except as otherwise agreed by the Administrative Agent and the L/C Issuer,
such Letter of Credit is in an initial stated amount less than $100,000, in the case
of a commercial Letter of Credit, or $50,000, in the case of a standby Letter of
Credit; or

     (D) such Letter of Credit is to be denominated in a currency other than
Dollars;

     (iv) The L/C Issuer shall not amend any Letter of Credit if the L/C Issuer would not be
permitted at such time to issue such Letter of Credit in its amended form under the terms
hereof.

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

     (vi) The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of
Credit issued by it and the documents associated therewith, and the L/C Issuer shall have
all of the benefits and immunities (A) provided to the Administrative Agent in Article
IX with respect to any acts taken or omissions suffered by the L/C Issuer in connection
with Letters of Credit issued by it or proposed to be issued by it and Issuer Documents
pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used
in Article IX included the L/C Issuer with respect to such acts or omissions, and
(B) as additionally provided herein with respect to the L/C Issuer.

     (b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension and
Auto-Reinstatement Letters of Credit.

     (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the
request of the Borrower delivered to the L/C Issuer (with a copy to the Administrative
Agent) in the form of a Letter of Credit Application, appropriately completed and signed by
a Responsible Officer of the Borrower. Such Letter of Credit Application must be received
by the L/C Issuer and the Administrative Agent not later than 11:00 a.m. at least
two Business Days (or such later date and time as the Administrative Agent and the L/C
Issuer may agree in a particular instance in their sole discretion) prior to the proposed
issuance date or date of amendment, as the case may be. In the case of a request for an
initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in
form and detail satisfactory to the L/C Issuer: (A) the proposed issuance date of the
requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the
expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents
to be presented by such beneficiary in case of any drawing thereunder; (F) the

32

 

full text of
any certificate to be presented by such beneficiary in case of any drawing thereunder; and
(G) such other matters as the L/C Issuer may require. In the case of a request for an
amendment of any outstanding Letter of Credit, such Letter of Credit Application shall
specify in form and detail satisfactory to the L/C Issuer (A) the Letter of Credit to be
amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the
nature of the proposed amendment; and (D) such other matters as the L/C Issuer may require.
Additionally, the Borrower shall furnish to the L/C Issuer and the Administrative Agent such
other documents and information pertaining to such requested Letter of Credit issuance or
amendment, including any Issuer Documents, as the L/C Issuer or the Administrative Agent may
require.

     (ii) Promptly after receipt of any Letter of Credit Application, the L/C Issuer will
confirm with the Administrative Agent (by telephone or in writing) that the Administrative
Agent has received a copy of such Letter of Credit Application from the Borrower and, if
not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Unless the
L/C Issuer has received written notice from any Lender, the Administrative Agent or any Loan
Party, at least one Business Day prior to the requested date of issuance or amendment of the
applicable Letter of Credit, that one or more applicable conditions contained in Article
IV shall not then be satisfied, then, subject to the terms and conditions hereof, the
L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the
Borrower or enter into the applicable amendment, as the case may be, in each case in
accordance with the L/C Issuer’s usual and customary business practices. Immediately upon
the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the L/C Issuer a risk participation
in such Letter of Credit in an amount equal to the product of such Lender’s Applicable
Percentage times the amount of such Letter of Credit.

     (iii) If the Borrower so requests in any applicable Letter of Credit Application, the
L/C Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that
has automatic extension provisions (each, an “Auto-Extension Letter of Credit”);
provided that any such Auto-Extension Letter of Credit must permit the L/C Issuer to prevent
any such extension at least once in each twelve-month period (commencing with the date of
issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not
later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be
agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the
L/C Issuer, the Borrower shall not be required to make a specific request to the L/C Issuer
for any such extension. Once an Auto-Extension Letter of Credit has been issued, the
Lenders shall be deemed to have authorized (but may not
require) the L/C Issuer to permit the extension of such Letter of Credit at any time to
an expiry date not later than the Letter of Credit Expiration Date; provided, however, that
the L/C Issuer shall not permit any such extension if (A) the L/C Issuer has determined that
it would not be permitted, or would have no obligation, at such time to issue such Letter of
Credit in its revised form (as extended) under the terms hereof (by reason of the provisions
of clause (ii) or (iii) of Section 2.03(a) or otherwise), or (B) it has received notice
(which may be by telephone or in writing) on or before the day that is seven Business Days
before the Non-Extension Notice Date (1) from the Administrative Agent

33

 

that the Required
Lenders have elected not to permit such extension or (2) from the Administrative Agent, any
Lender or the Borrower that one or more of the applicable conditions specified in Section
4.02 is not then satisfied, and in each such case directing the L/C Issuer not to permit
such extension.

     (iv) If the Borrower so requests in any applicable Letter of Credit Application, the
L/C Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that
permits the automatic reinstatement of all or a portion of the stated amount thereof after
any drawing thereunder (each, an “Auto-Reinstatement Letter of Credit”). Unless otherwise
directed by the L/C Issuer, the Borrower shall not be required to make a specific request to
the L/C Issuer to permit such reinstatement. Once an Auto-Reinstatement Letter of Credit
has been issued, except as provided in the following sentence, the Lenders shall be deemed
to have authorized (but may not require) the L/C Issuer to reinstate all or a portion of the
stated amount thereof in accordance with the provisions of such Letter of Credit.
Notwithstanding the foregoing, if such Auto-Reinstatement Letter of Credit permits the L/C
Issuer to decline to reinstate all or any portion of the stated amount thereof after a
drawing thereunder by giving notice of such non-reinstatement within a specified number of
days after such drawing (the “Non-Reinstatement Deadline”), the L/C Issuer shall not permit
such reinstatement if it has received a notice (which may be by telephone or in writing) on
or before the day that is five Business Days before the Non-Reinstatement Deadline (A) from
the Administrative Agent that the Required Lenders have elected not to permit such
reinstatement or (B) from the Administrative Agent, any Lender or the Borrower that one or
more of the applicable conditions specified in Section 4.02 is not then satisfied (treating
such reinstatement as an L/C Credit Extension for purposes of this clause) and, in each
case, directing the L/C Issuer not to permit such reinstatement.

     (v) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of
Credit to an advising bank with respect thereto or to the beneficiary thereof, the L/C
Issuer will also deliver to the Borrower and the Administrative Agent a true and complete
copy of such Letter of Credit or amendment.

     (c) Drawings and Reimbursements; Funding of Participations.

     (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a
drawing under such Letter of Credit, the L/C Issuer shall notify the Borrower and the
Administrative Agent thereof. Not later than 11:00 a.m. on the date of any payment by the
L/C Issuer under a Letter of Credit (each such date, an “Honor Date”), the Borrower
shall reimburse the L/C Issuer through the Administrative Agent in an amount equal to
the amount of such drawing. If the Borrower fails to so reimburse the L/C Issuer by
such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the
amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of
such Lender’s Applicable Percentage thereof. In such event, the Borrower shall be deemed to
have requested a Committed Borrowing of Base Rate Loans to be disbursed on the Honor Date in
an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples
specified in Section 2.02 for the principal amount of Base Rate Loans, but subject
to the amount of the unutilized portion of the Aggregate Commitments

34

 

and the conditions set
forth in Section 4.02 (other than the delivery of a Committed Loan Notice). Any
notice given by the L/C Issuer or the Administrative Agent pursuant to this Section
2.03(c)(i) may be given by telephone if immediately confirmed in writing;
provided that the lack of such an immediate confirmation shall not affect the
conclusiveness or binding effect of such notice.

     (ii) Each Lender shall upon any notice pursuant to Section 2.03(c)(i) make
funds available to the Administrative Agent for the account of the L/C Issuer at the
Administrative Agent’s Office in an amount equal to its Applicable Percentage of the
Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by
the Administrative Agent, whereupon, subject to the provisions of Section
2.03(c)(iii), each Lender that so makes funds available shall be deemed to have made a
Base Rate Committed Loan to the Borrower in such amount. The Administrative Agent shall
remit the funds so received to the L/C Issuer.

     (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a
Committed Borrowing of Base Rate Loans because the conditions set forth in Section
4.02 cannot be satisfied or for any other reason, the Borrower shall be deemed to have
incurred from the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that
is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with
interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment
to the Administrative Agent for the account of the L/C Issuer pursuant to Section
2.03(c)(ii) shall be deemed payment in respect of its participation in such L/C
Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its
participation obligation under this Section 2.03.

     (iv) Until each Lender funds its Committed Loan or L/C Advance pursuant to this
Section 2.03(c) to reimburse the L/C Issuer for any amount drawn under any Letter of
Credit, interest in respect of such Lender’s Applicable Percentage of such amount shall be
solely for the account of the L/C Issuer.

     (v) Each Lender’s obligation to make Committed Loans or L/C Advances to reimburse the
L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section
2.03(c), shall be absolute and unconditional and shall not be affected by any
circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right
which such Lender may have against the L/C Issuer, the Borrower or any other Person for any
reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other
occurrence, event or condition, whether or not similar to any of the foregoing;
provided, however, that each Lender’s obligation to make Committed Loans
pursuant to this
Section 2.03(c) is subject to the conditions set forth in Section 4.02
(other than delivery by the Borrower of a Committed Loan Notice). No such making of an L/C
Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse the
L/C Issuer for the amount of any payment made by the L/C Issuer under any Letter of Credit,
together with interest as provided herein.

     (vi) If any Lender fails to make available to the Administrative Agent for the account
of the L/C Issuer any amount required to be paid by such Lender pursuant to the

35

 

foregoing
provisions of this Section 2.03(c) by the time specified in Section
2.03(c)(ii), the L/C Issuer shall be entitled to recover from such Lender (acting
through the Administrative Agent), on demand, such amount with interest thereon for the
period from the date such payment is required to the date on which such payment is
immediately available to the L/C Issuer at a rate per annum equal to the greater of the
Federal Funds Rate and a rate determined by the L/C Issuer in accordance with banking
industry rules on interbank compensation, plus any administrative, processing or similar
fees customarily charged by the L/C Issuer in connection with the foregoing. If such Lender
pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute
such Lender’s Committed Loan included in the relevant Committed Borrowing or L/C Advance in
respect of the relevant L/C Borrowing, as the case may be. A certificate of the L/C Issuer
submitted to any Lender (through the Administrative Agent) with respect to any amounts owing
under this clause (vi) shall be conclusive absent manifest error.

     (d) Repayment of Participations.

     (i) At any time after the L/C Issuer has made a payment under any Letter of Credit and
has received from any Lender such Lender’s L/C Advance in respect of such payment in
accordance with Section 2.03(c), if the Administrative Agent receives for the
account of the L/C Issuer any payment in respect of the related Unreimbursed Amount or
interest thereon (whether directly from the Borrower or otherwise, including proceeds of
Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will
distribute to such Lender its Applicable Percentage thereof in the same funds as those
received by the Administrative Agent.

     (ii) If any payment received by the Administrative Agent for the account of the L/C
Issuer pursuant to Section 2.03(c)(i) is required to be returned under any of the
circumstances described in Section 10.05 (including pursuant to any settlement
entered into by the L/C Issuer in its discretion), each Lender shall pay to the
Administrative Agent for the account of the L/C Issuer its Applicable Percentage thereof on
demand of the Administrative Agent, plus interest thereon from the date of such demand to
the date such amount is returned by such Lender, at a rate per annum equal to the Federal
Funds Rate from time to time in effect. The obligations of the Lenders under this clause
shall survive the payment in full of the Obligations and the termination of this Agreement.

     (e) Obligations Absolute. The obligation of the Borrower to reimburse the L/C Issuer
for each drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute,
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including the following:

     (i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or
any other Loan Document;

     (ii) the existence of any claim, counterclaim, setoff, defense or other right that the
Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of
such Letter of Credit (or any Person for whom any such beneficiary or any such transferee
may be acting), the L/C Issuer or any other Person, whether in connection

36

 

with this
Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement
or instrument relating thereto, or any unrelated transaction;

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

     (iv) any payment by the L/C Issuer under such Letter of Credit against presentation of
a draft or certificate that does not strictly comply with the terms of such Letter of
Credit; or any payment made by the L/C Issuer under such Letter of Credit to any Person
purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of
creditors, liquidator, receiver or other representative of or successor to any beneficiary
or any transferee of such Letter of Credit, including any arising in connection with any
proceeding under any Debtor Relief Law; or

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

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

     (f) Role of L/C Issuer. Each Lender and the Borrower agree that, in paying any
drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any
document (other than any sight draft, certificates and documents expressly required by the Letter
of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document. None of the L/C Issuer, the
Administrative Agent, any of their respective Related Parties nor any correspondent, participant or
assignee of the L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in
connection herewith at the request or with the approval of the Lenders or the Required Lenders, as
applicable; (ii) any action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document
or instrument related to any Letter of Credit or Issuer Document. The Borrower hereby assumes all
risks of the acts or omissions of any beneficiary or transferee with respect to its use of any
Letter of Credit; provided, however, that this assumption is not intended to, and
shall not,
preclude the Borrower’s pursuing such rights and remedies as it may have against the
beneficiary or transferee at law or under any other agreement. None of the L/C Issuer, the
Administrative Agent, any of their respective Related Parties nor any correspondent, participant or
assignee of the L/C Issuer shall be liable or responsible for any of the matters described in
clauses (i) through (v) of Section 2.03(e); provided, however, that
anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the
L/C Issuer, and the L/C Issuer may be liable to the Borrower, to the extent, but only to the
extent, of any direct, as opposed to

37

 

consequential or exemplary, damages suffered by the Borrower
which the Borrower proves were caused by the L/C Issuer’s willful misconduct or gross negligence or
the L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by
the beneficiary of a sight draft and certificate(s) strictly complying with the terms and
conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the L/C
Issuer may accept documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary, and the L/C Issuer
shall not be responsible for the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective
for any reason.

     (g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the L/C
Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing
has resulted in an L/C Borrowing, or (ii) if, as of the Letter of Credit Expiration Date, any L/C
Obligation for any reason remains outstanding, the Borrower shall, in each case, immediately Cash
Collateralize the then Outstanding Amount of all L/C Obligations. Sections 2.05 and
8.02(c) set forth certain additional requirements to deliver Cash Collateral hereunder.
For purposes of this Section 2.03, Section 2.06 and Section 8.02(c),
“Cash Collateralize” means to pledge and deposit with or deliver to the Administrative
Agent, for the benefit of the L/C Issuer and the Lenders, as collateral for the L/C Obligations,
cash or deposit account balances pursuant to documentation in form and substance satisfactory to
the Administrative Agent and the L/C Issuer (which documents are hereby consented to by the
Lenders). Derivatives of such term have corresponding meanings. The Borrower hereby grants to the
Administrative Agent, for the benefit of the L/C Issuer and the Lenders, a security interest in all
such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Cash
Collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of
America.

     (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the L/C Issuer
and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an
Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby Letter of Credit,
and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently
published by the International Chamber of Commerce at the time of issuance shall apply to each
commercial Letter of Credit.

     (i) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the
account of each Lender in accordance with its Applicable Percentage a Letter of Credit fee (the
“Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Rate
times the daily amount available to be drawn under such Letter of Credit. For purposes of
computing the daily amount available to be drawn under any Letter of Credit, the amount of such
Letter of Credit shall be determined in accordance with Section 1.07. Letter of Credit
Fees shall be (i) due and
payable on the first Business Day after the end of each March, June, September and December,
commencing with the first such date to occur after the issuance of such Letter of Credit, on the
Letter of Credit Expiration Date and thereafter on demand and (ii) computed on a quarterly basis in
arrears. If there is any change in the Applicable Rate during any quarter, the daily amount
available to be drawn under each Letter of Credit shall be computed and multiplied by the
Applicable Rate separately for each period during such quarter that such Applicable Rate was in
effect. Notwithstanding anything to the contrary contained herein, upon the request of the

38

 

Required Lenders, while any Event of Default exists, all Letter of Credit Fees shall accrue at the
Default Rate.

     (j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The
Borrower shall pay directly to the L/C Issuer for its own account a fronting fee with respect to
each Letter of Credit, at the rate of 0.125% per annum, (i) with respect to each commercial Letter
of Credit, computed on the amount of such Letter of Credit and payable upon the issuance thereof,
(ii) with respect to any amendment of a commercial Letter of Credit increasing the amount of such
Letter of Credit, computed on the amount of such increase, and payable upon the effectiveness of
such amendment, and (iii) with respect to each standby Letter of Credit, computed on the daily
amount available to be drawn under such Letter of Credit on a quarterly basis in arrears, and due
and payable on the first Business Day after the end of each March, June, September and December in
respect of the most recently-ended quarterly period (or portion thereof, in the case of the first
payment), commencing with the first such date to occur after the issuance of such Letter of Credit,
on the Letter of Credit Expiration Date and thereafter on demand. For purposes of computing the
daily amount available to be drawn under any Letter of Credit, the amount of such Letter of Credit
shall be determined in accordance with Section 1.07. In addition, the Borrower shall pay
directly to the L/C Issuer for its own account the customary issuance, presentation, amendment and
other processing fees, and other standard costs and charges, of the L/C Issuer 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.

     (k) Conflict with Issuer Documents. In the event of any conflict between the terms
hereof and the terms of any Issuer Document, the terms hereof shall control.

     2.04 Swing Line Loans.

     (a) The Swing Line. Subject to the terms and conditions set forth herein, the Swing
Line Lender agrees, in reliance upon the agreements of the other Lenders set forth in this
Section 2.04, to make loans (each such loan, a “Swing Line Loan”) to the Borrower
from time to time on any Business Day during the Availability Period in an aggregate amount not to
exceed at any time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact that
such Swing Line Loans, when aggregated with the Applicable Percentage of the Outstanding Amount of
Committed Loans and L/C Obligations of the Lender acting as Swing Line Lender, may exceed the
amount of such Lender’s Commitment; provided, however, that after giving effect to
any Swing Line Loan, (i) the Total Outstandings shall not exceed the lesser of the Aggregate
Commitments and the Borrowing Base, and (ii) the aggregate Outstanding Amount of the Committed
Loans of any Lender, plus such Lender’s Applicable Percentage of the Outstanding Amount of
all L/C Obligations, plus such Lender’s Applicable Percentage of the Outstanding
Amount of all Swing Line Loans shall not exceed such Lender’s Commitment, and
provided, further, that the Borrower shall not use the proceeds of any Swing Line
Loan to refinance any outstanding Swing Line Loan. Within the foregoing limits, and subject to the
other terms and conditions hereof, the Borrower may borrow under this Section 2.04, prepay
under Section 2.06, and reborrow under this Section 2.04. Each Swing Line Loan
shall be a Base Rate Loan. Immediately upon the making of a Swing Line Loan, each Lender shall be
deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing Line
Lender a risk

39

 

participation in such Swing Line Loan in an amount equal to the product of such
Lender’s Applicable Percentage times the amount of such Swing Line Loan.

     (b) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the Borrower’s
irrevocable notice to the Swing Line Lender and the Administrative Agent, which may be given by
telephone. Each such notice must be received by the Swing Line Lender and the Administrative Agent
not later than 1:00 p.m. on the requested borrowing date, and shall specify (i) the amount to be
borrowed, which shall be a minimum of $100,000, and (ii) the requested borrowing date, which shall
be a Business Day. Each such telephonic notice must be confirmed promptly by delivery to the Swing
Line Lender and the Administrative Agent of a written Swing Line Loan Notice, appropriately
completed and signed by a Responsible Officer of the Borrower. Promptly after receipt by the Swing
Line Lender of any telephonic Swing Line Loan Notice, the Swing Line Lender will confirm with the
Administrative Agent (by telephone or in writing) that the Administrative Agent has also received
such Swing Line Loan Notice and, if not, the Swing Line Lender will notify the Administrative Agent
(by telephone or in writing) of the contents thereof. Unless the Swing Line Lender has received
notice (by telephone or in writing) from the Administrative Agent (including at the request of any
Lender) prior to 2:00 p.m. on the date of the proposed Swing Line Borrowing (A) directing the Swing
Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the
proviso to the first sentence of Section 2.04(a), or (B) that one or more of the applicable
conditions specified in Article IV is not then satisfied, then, subject to the terms and
conditions hereof, the Swing Line Lender will, not later than 3:00 p.m. on the borrowing date
specified in such Swing Line Loan Notice, make the amount of its Swing Line Loan available to the
Borrower at its office by crediting the account of the Borrower on the books of the Swing Line
Lender in immediately available funds.

     (c) Refinancing of Swing Line Loans.

     (i) The Swing Line Lender at any time in its sole and absolute discretion may request,
on behalf of the Borrower (which hereby irrevocably authorizes the Swing Line Lender to so
request on its behalf), that each Lender make a Base Rate Committed Loan in an amount equal
to such Lender’s Applicable Percentage of the amount of Swing Line Loans then outstanding.
Such request shall be made in writing (which written request shall be deemed to be a
Committed Loan Notice for purposes hereof) and in accordance with the requirements of
Section 2.02, without regard to the minimum and multiples specified therein for the
principal amount of Base Rate Loans, but subject to the unutilized portion of the Aggregate
Commitments and the conditions set forth in Section 4.02. The Swing Line Lender
shall furnish the Borrower with a copy of the applicable Committed Loan Notice promptly
after delivering such notice to the Administrative Agent. Each Lender shall make an amount
equal to its Applicable Percentage of the amount specified in such Committed Loan Notice
available to the Administrative Agent
in immediately available funds for the account of the Swing Line Lender at the
Administrative Agent’s Office not later than 1:00 p.m. on the day specified in such
Committed Loan Notice, whereupon, subject to Section 2.04(c)(ii), each Lender that
so makes funds available shall be deemed to have made a Base Rate Committed Loan to the
Borrower in such amount. The Administrative Agent shall remit the funds so received to the
Swing Line Lender.

40

 

     (ii) If for any reason any Swing Line Loan cannot be refinanced by such a Committed
Borrowing in accordance with Section 2.04(c)(i), the request for Base Rate Committed
Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request
by the Swing Line Lender that each of the Lenders fund its risk participation in the
relevant Swing Line Loan and each Lender’s payment to the Administrative Agent for the
account of the Swing Line Lender pursuant to Section 2.04(c)(i) shall be deemed
payment in respect of such participation.

     (iii) If any Lender fails to make available to the Administrative Agent for the account
of the Swing Line Lender any amount required to be paid by such Lender pursuant to the
foregoing provisions of this Section 2.04(c) by the time specified in Section
2.04(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting
through the Administrative Agent), on demand, such amount with interest thereon for the
period from the date such payment is required to the date on which such payment is
immediately available to the Swing Line Lender at a rate per annum equal to the greater of
the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with
banking industry rules on interbank compensation, plus any administrative, processing or
similar fees customarily charged by the Swing Line Lender in connection with the foregoing.
If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid
shall constitute such Lender’s Committed Loan included in the relevant Committed Borrowing
or funded participation in the relevant Swing Line Loan, as the case may be. A certificate
of the Swing Line Lender submitted to any Lender (through the Administrative Agent) with
respect to any amounts owing under this clause (iii) shall be conclusive absent manifest
error.

     (iv) Each Lender’s obligation to make Committed Loans or to purchase and fund risk
participations in Swing Line Loans pursuant to this Section 2.04(c) shall be
absolute and unconditional and shall not be affected by any circumstance, including (A) any
setoff, counterclaim, recoupment, defense or other right which such Lender may have against
the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the
occurrence or continuance of a Default, or (C) any other occurrence, event or condition,
whether or not similar to any of the foregoing; provided, however, that each
Lender’s obligation to make Committed Loans pursuant to this Section 2.04(c) is
subject to the conditions set forth in Section 4.02. No such funding of risk
participations shall relieve or otherwise impair the obligation of the Borrower to repay
Swing Line Loans, together with interest as provided herein.

     (d) Repayment of Participations.

     (i) At any time after any Lender has purchased and funded a risk participation in a
Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line
Loan, the Swing Line Lender will distribute to such Lender its Applicable Percentage thereof
in the same funds as those received by the Swing Line Lender.

     (ii) If any payment received by the Swing Line Lender in respect of principal or
interest on any Swing Line Loan is required to be returned by the Swing Line Lender under
any of the circumstances described in Section 10.05 (including pursuant to any

41

 

settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay
to the Swing Line Lender its Applicable Percentage thereof on demand of the Administrative
Agent, plus interest thereon from the date of such demand to the date such amount is
returned, at a rate per annum equal to the Federal Funds Rate. The Administrative Agent
will make such demand upon the request of the Swing Line Lender. The obligations of the
Lenders under this clause shall survive the payment in full of the Obligations and the
termination of this Agreement.

     (e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be
responsible for invoicing the Borrower for interest on the Swing Line Loans. Until each Lender
funds its Base Rate Committed Loan or risk participation pursuant to this Section 2.04 to
refinance such Lender’s Applicable Percentage of any Swing Line Loan, interest in respect of such
Applicable Percentage shall be solely for the account of the Swing Line Lender.

     (f) Payments Directly to Swing Line Lender. The Borrower shall make all payments of
principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender.

     2.05 Borrowing Base

     (a) Initial Borrowing Base. During the period from the Closing Date until the next
Determination Date the Borrowing Base shall be $300,000,000.

     (b) Subsequent Determinations of the Borrowing Base. Upon each designation of a new
Borrowing Base on a Scheduled Determination or a Special Determination, the Administrative Agent
shall notify the Borrower of the new Borrowing Base which designation shall take effect immediately
on the date such notice is sent (each such date, a “Determination Date”) and shall remain
in effect until, but not including, the next Determination Date. The Borrowing Base shall be
determined in accordance with the following methodology:

          (i) By April 1 and October 1 of each year beginning April 1, 2007, the Borrower shall furnish
to the Administrative Agent (with sufficient copies for each Lender of any information provided on
paper, computer disks, or other tangible media) the Engineering Report then required under Section
6.01(d) or (e) together with all information, reports and data that the Administrative Agent
requests concerning the businesses and properties of the Borrower and its Subsidiaries (including
their Oil and Gas Properties and the reserves and production relating thereto). As promptly as
reasonably practicable after receiving such Engineering Report, information, reports and data, the
Administrative Agent shall propose a Borrowing Base following the procedures set forth in Section
2.05(b)(iii) below. Each such determination of the
Borrowing Base is herein called a “Scheduled Determination”. If the Borrower does not
furnish all such information, reports and data by the date specified in the first sentence of this
Section, the Administrative Agent may nonetheless designate the Borrowing Base at any amount that
Required Lenders determine (or, in the case of an increase, that all the Lenders determine) and the
Borrowing Base may similarly be designated from time to time thereafter until each Lender receives
all such information, reports and data, whereupon the Lenders shall designate a new Borrowing Base
as described above.

          (ii) In addition to Scheduled Determinations, the Borrower may request the Lenders to make
additional determinations of the Borrowing Base (x) twice during the twelve

42

 

months following the
Closing Date and (y) thereafter once during each twelve month interval between Scheduled
Determinations, and the Administrative Agent also may (and at the request of Required Lenders must)
request the Lenders to make an additional determination of the Borrowing Base (x) once during the
twelve months following the Closing Date and (y) thereafter once during each twelve month interval
between Scheduled Determinations. The Administrative Agent shall give notice to the Borrower of
any such request made by the Administrative Agent to the Lenders. The Borrower shall submit any
such request made by Borrower to Administrative Agent and each Lender and, at the time of such
request, the Borrower shall (A) deliver to the Administrative Agent and each Lender an updated
Engineering Report prepared either by the Borrower or by independent petroleum engineers, and (B)
notify the Administrative Agent and each Lender of the Borrowing Base requested by the Borrower.
Any determination of the Borrowing Base made pursuant to a request under this clause (ii) is herein
called a “Special Determination”. Any Special Determination shall be made by Lenders in
accordance with the procedures set forth in Section 2.05(b)(iii), provided, however, that the
Borrower shall not be required to deliver an updated Engineering Report to the Administrative Agent
and Lenders in connection with any Special Determination requested by the Administrative Agent.

          (iii) The Administrative Agent shall (within 30 days after receiving the information, if any,
required for a Scheduled Determination or a Special Determination) propose to the Lenders a
specific Borrowing Base amount for the Lenders to approve or disapprove. Within 15 days thereafter
each Lender shall respond to the Administrative Agent in writing, either approving such proposed
amount or setting out a reasonable alternative amount (based on the criteria described in clause
(v) below), and any Lender’s failure to respond to such proposal within such time will be deemed a
disapproval of the proposed amount. After receiving such responses or deemed responses from all
Lenders, the Administrative Agent will designate the new Borrowing Base at the highest amount
approved (i) by all Lenders, in the case of an increase to the then current Borrowing Base, or (ii)
at the highest amount approved by Required Lenders, in the case of a reduction to or continuation
of the then current Borrowing Base.

          (iv) In addition to the foregoing, the Administrative Agent and Lenders shall also have the
right to adjust the Borrowing Base (which shall not count as a Special Determination but which
shall otherwise be done in accordance with the procedures set forth in Section 2.05(b)(iii)) if the
Borrower or any Subsidiaries sell or otherwise transfer (excluding transfers to the Borrower or a
Subsidiary of the Borrower that is a Guarantor) Oil and Gas Properties that, on a cumulative basis
since the then most recent Determination Date, represent more than ten percent of the net present
value of all of their proved reserves, as determined in the most recently delivered Engineering
Report.

          (v) Each redetermination of the Borrowing Base pursuant to this Section 2.05 shall be made in
good faith by all of the Lenders and the Administrative Agent, in the exercise of their reasonable
discretion and in accordance with their respective customary and prudent standards for oil and gas
lending and credit transactions as they exist at such time. Without limiting such discretion,
Borrower acknowledges and agrees that the Administrative Agent and the Lenders (i) may make such
assumptions regarding appropriate existing and projected pricing for Hydrocarbons as they deem
appropriate in their discretion, (ii) may make such assumptions regarding projected rates and
quantities of future production of Hydrocarbons from the Oil and Gas Properties owned by Borrower
and its Subsidiaries as they deem appropriate in their discretion, (iii) may consider the projected
cash requirements of Borrower and its Subsidiaries,

43

 

           (iv) are not required to consider any asset
other than Proved Reserves owned by Borrower and its Subsidiaries, and (v) may make such other
assumptions, considerations and exclusions as they deems appropriate in the exercise of their
discretion. It is further acknowledged and agreed that the Administrative Agent and the Lenders may
consider such other credit factors as they deem appropriate in the exercise of their discretion.

     (c) Borrowing Base Deficiency. If a Borrowing Base Deficiency exists at any time, the
Borrower shall, within ten (10) days after being notified of such Borrowing Base Deficiency,
provide written notice (the “Election Notice”) to Lender stating the action which Borrower
proposes to take to remedy such Borrowing Base Deficiency, and the Borrower shall thereafter, at
its option, do one or a combination of the following in an aggregate amount sufficient to eliminate
such Borrowing Base Deficiency:

          (i) within ten (10) days following the delivery of such Election Notice, make a prepayment of
the Loans,

          (ii) pay monthly installments of the Outstanding Amount of the Loans over a term and in an
amount satisfactory to the Administrative Agent, but in any event not to exceed six months, by
immediately dedicating a sufficient amount of monthly cash flow from the Oil and Gas Properties of
the Borrower and its Subsidiaries,

          (iii) within thirty (30) days following the delivery of the Election Notice, submit additional
Oil and Gas Properties to the Administrative Agent for evaluation as Borrowing Base Properties
which the Administrative Agent, in its sole discretion, determines have a value sufficient to
increase the Borrowing Base by at least the amount of the Borrowing Base Deficiency (after giving
effect to other actions taken pursuant to this Section 2.05(c) that have the effect of reducing
such Borrowing Base Deficiency) , and/or

          (iv) within thirty (30) days following the delivery of such Election Notice, apply the Net
Cash Proceeds from a Disposition permitted by Section 7.05(g) to reduce the Borrowing Base
Deficiency after giving effect to any reduction of the Borrowing Base as determined by the Required
Lenders as a result of such sale.

     2.06 Prepayments.

     (a) Optional.

          (i) The Borrower may, upon notice to the Administrative Agent, at any time or from time to
time voluntarily prepay Committed Loans in whole or in part without premium or penalty;
provided that (i) such notice must be received by the Administrative Agent not later
than 11:00 a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate
Loans and (B) on the date of prepayment of Base Rate Committed Loans; (ii) any prepayment of
Eurodollar Rate Loans shall be in a principal amount of $5,000,000 or a whole multiple of
$1,000,000 in excess thereof; and (iii) any prepayment of Base Rate Committed Loans shall be in a
principal amount of $500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if
less, the entire principal amount thereof then outstanding. Each such notice shall specify the
date and amount of such prepayment and the Type(s) of Committed Loans to be prepaid and, if
Eurodollar Rate Loans are to be prepaid, the Interest Period(s) of such Loans. The Administrative
Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of
such Lender’s Applicable Percentage of such prepayment. If such notice is given

44

 

by the Borrower,
the Borrower shall make such prepayment and the payment amount specified in such notice shall be
due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be
accompanied by all accrued interest on the amount prepaid, together with any additional amounts
required pursuant to Section 3.05. Each such prepayment shall be applied to the Committed
Loans of the Lenders in accordance with their respective Applicable Percentages.

          (ii) The Borrower may, upon notice to the Swing Line Lender (with a copy to the Administrative
Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part
without premium or penalty; provided that (i) such notice must be received by the Swing
Line Lender and the Administrative Agent not later than 1:00 p.m. on the date of the prepayment,
and (ii) any such prepayment shall be in a minimum principal amount of $100,000. Each such notice
shall specify the date and amount of such prepayment. If such notice is given by the Borrower, the
Borrower shall make such prepayment and the payment amount specified in such notice shall be due
and payable on the date specified therein.

     (b) Mandatory.

          (i) If for any reason the Total Outstandings at any time exceed the Aggregate Commitments then
in effect, the Borrower shall immediately prepay Loans and/or Cash Collateralize the L/C
Obligations in an aggregate amount equal to such excess; provided, however, that
the Borrower shall not be required to Cash Collateralize the L/C Obligations pursuant to this
Section 2.06(b) unless after the prepayment in full of the Loans the Total Outstandings
exceed the Aggregate Commitments then in effect.

          (ii) If the Borrower or any of its Subsidiaries Disposes of any property under Section 7.05(g)
which results in the realization by such Person of Net Cash Proceeds, the Borrower shall use the
Net Cash Proceeds to eliminate any Borrowing Base Deficiency resulting from such sale; provided
that, the proceeds of any Disposition permitted by Section 7.05(g) shall not constitute Net Cash
Proceeds to the extent that (A) such proceeds are reinvested in replacement properties or assets,
or other productive properties or assets, acquired by the Borrower or a Subsidiary of a kind then
used or usable in the business of the applicable Person (with equal or greater aggregate Attributed
Value) within 180 days from the date of receipt thereof or (B) if the applicable Borrower or
Subsidiary intends to acquire replacement properties or assets, or other productive properties or
assets, with such proceeds as part of a like-kind exchange under Section 1031 of the Code, the
potential replacement properties or assets are identified by such Borrower or Subsidiary within
180 days from the date the ownership to the
sold assets is transferred to the buyer of such property and the proceeds from such property
are reinvested to acquire such replacement properties or assets (with equal or greater aggregate
Attributed Value) within 180 days from the date the ownership to the sold assets is transferred to
the buyer of such property; provided further that, the proceeds of any Casualty Event shall not
constitute Net Cash Proceeds to the extent that such proceeds are reinvested in replacement
properties or assets, or other productive properties or assets, acquired by the Borrower or a
Guarantor of a kind then used or usable in the business of the applicable Person (with equal or
greater aggregate Attributed Value) within 180 days from the date of receipt thereof.

45

 

          (iii) Upon the incurrence or issuance by the Borrower or any of its Subsidiaries of any
Indebtedness (other than Indebtedness expressly permitted to be incurred or issued pursuant to
Section 7.03, the Borrower shall prepay an aggregate principal amount of Loans equal to
100% of all Net Cash Proceeds received therefrom immediately upon receipt thereof by the Borrower
or such Subsidiary (such prepayments to be applied as set forth in clause (iv) below).

          (iv) Prepayments of the Total Outstandings made pursuant to this Section 2.06(b), first, shall
be applied ratably to the L/C Borrowings, second, shall be applied ratably to the
outstanding Loans, and, third, shall be used to Cash Collateralize the remaining L/C
Obligations. Upon the drawing of any Letter of Credit that has been Cash Collateralized, the funds
held as Cash Collateral shall be applied (without any further action by or notice to or from the
Borrower or any other Loan Party) to reimburse the L/C Issuer or the Lenders, as applicable.

     2.07 Termination or Reduction of Commitments. The Borrower may, upon notice to the
Administrative Agent, terminate the Aggregate Commitments, or from time to time permanently reduce
the Aggregate Commitments; provided that (i) any such notice shall be received by the
Administrative Agent not later than 11:00 a.m. five Business Days prior to the date of termination
or reduction, (ii) any such partial reduction shall be in an aggregate amount of $10,000,000 or any
whole multiple of $1,000,000 in excess thereof, (iii) the Borrower shall not terminate or reduce
the Aggregate Commitments if, after giving effect thereto and to any concurrent prepayments
hereunder, the Total Outstandings would exceed the Aggregate Commitments, and (iv) if, after giving
effect to any reduction of the Aggregate Commitments, the Letter of Credit Sublimit or the Swing
Line Sublimit exceeds the amount of the Aggregate Commitments, such Sublimit shall be automatically
reduced by the amount of such excess. The Administrative Agent will promptly notify the Lenders of
any such notice of termination or reduction of the Aggregate Commitments. Any reduction of the
Aggregate Commitments shall be applied to the Commitment of each Lender according to its Applicable
Percentage. All fees accrued until the effective date of any termination of the Aggregate
Commitments shall be paid on the effective date of such termination.

     2.08 Repayment of Loans.

     (a) The Borrower shall repay to the Lenders on the Maturity Date the aggregate principal
amount of Committed Loans outstanding on such date.

     (b) The Borrower shall repay each Swing Line Loan on the earlier to occur of (i) demand by the
Swing Line Lender and (ii) the Maturity Date.

     2.09 Interest.

     (a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall
bear interest on the outstanding principal amount thereof for each Interest Period at a rate per
annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate; (ii)
each Base Rate Committed Loan shall bear interest on the outstanding
principal amount thereof
from the applicable borrowing date at a rate per annum equal to the Base Rate plus the
Applicable Rate; and (iii) each Swing Line Loan shall bear interest on the outstanding principal

46

 

amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate
plus the Applicable Rate.

     (b) (i) If any amount of principal of any Loan is not paid when due (without regard to any
applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount
shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Laws.

     (ii) If any amount (other than principal of any Loan) payable by the Borrower under any
Loan Document is not paid when due (without regard to any applicable grace periods), whether
at stated maturity, by acceleration or otherwise, then upon the request of the Required
Lenders, such amount shall thereafter bear interest at a fluctuating interest rate per annum
at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

     (iii) Upon the request of the Required Lenders, while any Event of Default exists, the
Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder
at a fluctuating interest rate per annum at all times equal to the Default Rate to the
fullest extent permitted by applicable Laws.

     (iv) Accrued and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand.

     (c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date
applicable thereto and at such other times as may be specified herein. Interest hereunder shall be
due and payable in accordance with the terms hereof before and after judgment, and before and after
the commencement of any proceeding under any Debtor Relief Law.

     2.10 Fees. In addition to certain fees described in subsections (i) and (j) of Section
2.03:

     (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the
account of each Lender in accordance with its Applicable Percentage, a commitment fee equal to the
Applicable Rate times the daily amount of the Available Borrowing Base. The commitment fee
shall accrue at all times during the Availability Period, including at any time during which one or
more of the conditions in Article IV is not met, and shall be due and payable quarterly in
arrears on the last Business Day of each March, June, September and December, commencing with the
first such date to occur after the Closing Date, and on the last day of the Availability Period.
The commitment fee shall be calculated quarterly in arrears, and if there is any change in the
Applicable Rate during any quarter, the actual daily amount shall be computed and multiplied by the
Applicable Rate separately for each period during such quarter that such Applicable Rate was in
effect. For the purposes of computation of the Commitment Fee, Swing Line Loans shall not be
counted as usage of the Aggregate Commitments.

     (b) Other Fees. (i) The Borrower shall pay to the Arranger and the Administrative
Agent for their own respective accounts fees in the amounts and at the times specified in the Fee

47

 

Letter. Such fees shall be fully earned when paid and shall not be refundable for any reason
whatsoever.

     (ii) The Borrower shall pay to the Lenders such fees as shall have been separately agreed upon
in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid
and shall not be refundable for any reason whatsoever.

     2.11 Computation of Interest and Fees. All computations of interest for Base Rate Loans when the
Base Rate is determined by Bank of America’s “prime rate” shall be made on the basis of a year of
365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed (which results in
more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year).
Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a
Loan, or any portion thereof, for the day on which the Loan or such portion is paid,
provided that any Loan that is repaid on the same day on which it is made shall, subject to
Section 2.13(a), bear interest for one day. Each determination by the Administrative Agent
of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent
manifest error.

     2.12 Evidence of Debt.

     (a) The Credit Extensions made by each Lender shall be evidenced by one or more accounts or
records maintained by such Lender and by the Administrative Agent in the ordinary course of
business. The accounts or records maintained by the Administrative Agent and each Lender shall be
conclusive absent manifest error of the amount of the Credit Extensions made by the Lenders to the
Borrower and the interest and payments thereon. Any failure to so record or any error in doing so
shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any
amount owing with respect to the Obligations. In the event of any conflict between the accounts
and records maintained by any Lender and the accounts and records of the Administrative Agent in
respect of such matters, the accounts and records of the Administrative Agent shall control in the
absence of manifest error. Upon the request of any Lender made through the Administrative Agent,
the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Note,
which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender may
attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and
maturity of its Loans and payments with respect thereto.

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

48

 

     2.13 Payments Generally; Administrative Agent’s Clawback.

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

     (b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the
Administrative Agent shall have received notice from a Lender prior to the proposed date of any
Committed Borrowing of Eurodollar Rate Loans (or, in the case of any Committed Borrowing of Base
Rate Loans, prior to 12:00 noon on the date of such Committed Borrowing) that such Lender will not
make available to the Administrative Agent such Lender’s share of such Committed Borrowing, the
Administrative Agent may assume that such Lender has made such share available on such date in
accordance with Section 2.02 (or, in the case of a Committed Borrowing of Base Rate Loans,
that such Lender has made such share available in accordance with and at the time required by
Section 2.02) and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. In such event, if a Lender has not in fact made its share of the applicable
Committed Borrowing available to the Administrative Agent, then the applicable Lender and the
Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding
amount in immediately available funds with interest thereon, for each day from and including the
date such amount is made available to the Borrower to but excluding the date of payment to the
Administrative Agent, at (A) in the case of a payment to be made by such Lender, the greater of the
Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation, plus any administrative, processing or similar fees
customarily charged by the Administrative Agent in connection with the foregoing, and (B) in the
case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If
the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an
overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of
such interest paid by the Borrower for such period. If such Lender pays its share of the
applicable Committed Borrowing to the Administrative Agent, then the amount so paid shall
constitute such Lender’s Committed Loan included in such Committed Borrowing. Any payment by the
Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall
have failed to make such payment to the Administrative Agent.

     (ii) Payments by Borrower; Presumptions by Administrative Agent. Unless the
Administrative Agent shall have received notice from the Borrower prior to the date on which
any payment is due to the Administrative Agent for the account of the Lenders or the L/C
Issuer

49

 

hereunder that the Borrower will not make such payment, the Administrative Agent may assume
that the Borrower has made such payment on such date in accordance herewith and may, in reliance
upon such assumption, distribute to the Lenders or the L/C Issuer, as the case may be, the amount
due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or
the L/C Issuer, as the case may be, severally agrees to repay to the Administrative Agent forthwith
on demand the amount so distributed to such Lender or the L/C Issuer, in immediately available
funds with interest thereon, for each day from and including the date such amount is distributed to
it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal
Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

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

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

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

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

     2.14 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or
counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the
Committed Loans made by it, or the participations in L/C Obligations or in Swing Line Loans held by
it resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such
Committed Loans or participations and accrued interest thereon greater than its pro
rata share thereof as provided herein, then the Lender receiving such greater proportion
shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value)
participations in the Committed Loans and subparticipations in L/C Obligations and in Swing Line
Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with

50

 

the aggregate amount of principal of and accrued interest on their respective Committed Loans and
other amounts owing them, provided that:

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

     (ii) the provisions of this Section shall not be construed to apply to (x) any payment
made by the Borrower pursuant to and in accordance with the express terms of this Agreement
or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Committed Loans or subparticipations in L/C Obligations or Swing
Line Loans to any assignee or participant, other than to the Borrower or any Subsidiary
thereof (as to which the provisions of this Section shall apply).

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

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 Taxes.

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

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

     (c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative
Agent, each Lender and the L/C Issuer, within 10 days after demand therefor, for the full amount of
any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) paid by the
Administrative Agent, such Lender or the L/C Issuer, as the case may be, and any penalties,

51

 

interest and reasonable expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or liability delivered to
the Borrower by a Lender or the L/C Issuer (with a copy to the Administrative Agent), or by the
Administrative Agent on its own behalf or on behalf of a Lender or the L/C Issuer, shall be
conclusive absent manifest error.

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

     (e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident
for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments
hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by
the Borrower or the Administrative Agent, such properly completed and executed documentation
prescribed by applicable law as will permit such payments to be made without withholding or at a
reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the
Administrative Agent, shall deliver such other documentation prescribed by applicable law or
reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the
Administrative Agent to determine whether or not such Lender is subject to backup withholding or
information reporting requirements.

     Without limiting the generality of the foregoing, in the event that the Borrower is resident
for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior
to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to
time thereafter upon the request of the Borrower or the Administrative Agent, but only if such
Foreign Lender is legally entitled to do so), whichever of the following is applicable:

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

     (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

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

52

 

     (iv) any other form prescribed by applicable law as a basis for claiming exemption from
or a reduction in United States Federal withholding tax duly completed together with such
supplementary documentation as may be prescribed by applicable law to permit the Borrower to
determine the withholding or deduction required to be made.

     (f) Treatment of Certain Refunds. If the Administrative Agent, any Lender or the L/C
Issuer determines, in its sole discretion, that it has received a refund of any Taxes or Other
Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has
paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to
such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the
Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund),
net of all out-of-pocket expenses of the Administrative Agent, such Lender or the L/C Issuer, as
the case may be, and without interest (other than any interest paid by the relevant Governmental
Authority with respect to such refund), provided that the Borrower, upon the request of the
Administrative Agent, such Lender or the L/C Issuer, agrees to repay the amount paid over to the
Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental
Authority) to the Administrative Agent, such Lender or the L/C Issuer in the event the
Administrative Agent, such Lender or the L/C Issuer is required to repay such refund to such
Governmental Authority. This subsection shall not be construed to require the Administrative
Agent, any Lender or the L/C Issuer to make available its tax returns (or any other information
relating to its taxes that it deems confidential) to the Borrower or any other Person.

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

     3.03 Inability to Determine Rates. If the Required Lenders determine that for any reason in
connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof
that (a) Dollar deposits are not being offered to banks in the London interbank eurodollar market
for the applicable amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and
reasonable means do not exist for determining the Eurodollar Rate for any requested Interest Period
with respect to a proposed Eurodollar Rate Loan, or (c) the Eurodollar Rate for any
requested Interest Period with respect to a proposed Eurodollar Rate

53

 

Loan does not adequately
and fairly reflect the cost to such Lenders of funding such Loan, the Administrative Agent will
promptly so notify the Borrower and each Lender. Thereafter, the obligation of the Lenders to make
or maintain Eurodollar Rate Loans shall be suspended until the Administrative Agent (upon the
instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, the
Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of
Eurodollar Rate Loans or, failing that, will be deemed to have converted such request into a
request for a Committed Borrowing of Base Rate Loans in the amount specified therein.

     3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

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

     (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, any Lender (except any reserve requirement
contemplated by Section 3.04(e)) or the L/C Issuer;

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

     (iii) impose on any Lender or the L/C Issuer or the London interbank market any other
condition, cost or expense affecting this Agreement or Eurodollar Rate Loans made by such
Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Rate Loan (or of maintaining its obligation to make any such Loan), or
to increase the cost to such Lender or the L/C Issuer of participating in, issuing or maintaining
any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of
Credit), or to reduce the amount of any sum received or receivable by such Lender or the L/C Issuer
hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or
the L/C Issuer, the Borrower will pay to such Lender or the L/C Issuer, as the case may be, such
additional amount or amounts as will compensate such Lender or the L/C Issuer, as the case may be,
for such additional costs incurred or reduction suffered.

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

54

 

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

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

     (d) Delay in Requests. Failure or delay on the part of any Lender or the L/C Issuer
to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a
waiver of such Lender’s or the L/C Issuer’s right to demand such compensation, provided
that the Borrower shall not be required to compensate a Lender or the L/C Issuer pursuant to the
foregoing provisions of this Section for any increased costs incurred or reductions suffered more
than 180 days prior to the date that such Lender or the L/C Issuer, as the case may be, notifies
the Borrower of the Change in Law giving rise to such increased costs or reductions and of such
Lender’s or the L/C Issuer’s intention to claim compensation therefor (except that, if the Change
in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period
referred to above shall be extended to include the period of retroactive effect thereof).

     (e) Reserves on Eurodollar Rate Loans. The Borrower shall pay to each Lender, as long
as such Lender shall be required to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency
liabilities”), additional interest on the unpaid principal amount of each Eurodollar Rate Loan
equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by
such Lender in good faith, which determination shall be conclusive), which shall be due and payable
on each date on which interest is payable on such Loan, provided the Borrower shall have received
at least 10 days’ prior notice (with a copy to the Administrative Agent) of such additional
interest from such Lender. If a Lender fails to give notice 10 days prior to the relevant Interest
Payment Date, such additional interest shall be due and payable 10 days from receipt of such
notice.

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

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

55

 

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

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

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

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

     3.06 Mitigation Obligations; Replacement of Lenders.

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

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

     3.07 Survival. All of the Borrower’s obligations under this Article III shall survive
termination of the Aggregate Commitments and repayment of all other Obligations hereunder.

Subsidiaries.

     5.10 Insurance. The properties of the Borrower and its Subsidiaries are insured with financially
sound and reputable insurance companies not Affiliates of the Borrower, in such amounts, with such

     5.13 Subsidiaries; Equity Interests; Loan Parties. As of the Closing Date, no Loan Party has any
Subsidiaries other than those specifically disclosed in Part (a) of Schedule 5.13, and all
of the outstanding Equity Interests in such Subsidiaries have been validly issued, are (in the case
of corporate securities) fully paid and non-assessable and are owned by a Loan Party in the amounts
specified on Part (a) of Schedule 5.13 free and clear of all Liens except those created
under the Collateral Documents or permitted by Section 7.01. As of the Closing Date, no Loan Party
has any equity investments in any other corporation or entity other than those specifically
disclosed in Part (b) of Schedule 5.13. Set forth on Part (c) of Schedule 5.13 is
a complete and accurate list of all Loan Parties, showing as of the Closing Date (as to each Loan
Party) the jurisdiction of its incorporation, the address of its principal place of business and
its U.S. taxpayer identification number or, in the case of any non-U.S. Loan Party that does not
have a U.S. taxpayer identification number, its unique identification number issued to it by the
jurisdiction of its incorporation. As of the Closing Date, the copy of the charter of each Loan
Party and each amendment thereto provided pursuant to Section 4.01(a)(vii) is a true and
correct copy of each such document, each of which is valid and in full force and effect.

     5.14 Margin Regulations; Investment Company Act. (a) The Borrower is not engaged and will not
engage, principally or as one of its important activities, in the business of purchasing or
carrying margin stock (within the meaning of Regulation U issued by the FRB), or extending credit
for the purpose of purchasing or carrying margin stock.

     (b) None of the Borrower, any Person Controlling the Borrower, or any Subsidiary is or is
required to be registered as an “investment company” under the Investment Company Act of 1940.

     5.15 Disclosure. The Borrower has disclosed to the Administrative Agent and the Lenders all
agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries
is subject, and all other matters known to it, that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect. No report, financial statement,
certificate or other information furnished in writing by or on behalf of any Loan Party to the
Administrative Agent or any Lender in connection with the transactions contemplated hereby and the
negotiation of this Agreement or delivered hereunder or under any other Loan Document (in each case
as modified or supplemented by other information so furnished) contains as of the date so furnished
any material misstatement of fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading;
provided that, with respect to projected financial information, the Borrower represents
only that such information was prepared in good faith based upon assumptions believed to be
reasonable at the time. There are no statements or conclusions in any Engineering Report which are
based upon or include misleading information or fail to take into account material information
regarding the matters reported therein, it being understood that projections
concerning volumes attributable to the Oil and Gas Properties and production and cost
estimates contained in each Engineering Report are necessarily based upon professional opinions,
estimates and projections and that the Borrower and the Subsidiaries do not warrant that such
opinions, estimates and projections will ultimately prove to have been accurate.

66

 

     5.16 Compliance with Laws. Each Loan Party and each Subsidiary thereof is in compliance in all
material respects with the requirements of all Laws and all orders, writs, injunctions and decrees
applicable to it or to its properties, except in such instances in which (a) such requirement of
Law or order, writ, injunction or decree is being contested in good faith by appropriate
proceedings diligently conducted or (b) the failure to comply therewith, either individually or in
the aggregate, could not reasonably be expected to have a Material Adverse Effect.

     5.17 Solvency. Each Loan Party is, individually and together with its Subsidiaries on a
Consolidated basis, Solvent.

     5.18 Casualty, Etc. Neither the businesses nor the properties of any Loan Party or any of its
Subsidiaries are affected by any fire, explosion, accident, strike, lockout or other labor dispute,
drought, storm, hail, earthquake, embargo, act of God or of the public enemy or other casualty
(whether or not covered by insurance) that, either individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect.

     5.19 Labor Matters.

          There are no collective bargaining agreements or Multiemployer Plans covering the employees of
the Borrower or any of its Subsidiaries as of the Closing Date and neither the Borrower nor any
Subsidiary has suffered any strikes, walkouts, work stoppages or other material labor difficulty
within the last five years that, either individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

     5.20 Collateral Documents. The provisions of the Collateral Documents are effective to create in
favor of the Administrative Agent for the benefit of the Secured Parties a legal, valid and
enforceable first priority Lien (subject to Liens permitted by Section 7.01) on all right, title
and interest of the respective Loan Parties in the Collateral described therein. Except as
expressly contemplated hereby and by the Collateral Documents, no filing or other action will be
necessary to perfect or protect such Liens.

     5.21 Engineered Oil and Gas Properties.

     (a) The Borrower or another Loan Party has good and defensible title to all Engineered Oil
and Gas Properties, free and clear of all Liens except as permitted pursuant to Section
7.01 and Immaterial Title Deficiencies. With the exception of Immaterial Title Deficiencies,
all such Oil and Gas Properties are valid, subsisting, and in full force and effect, and all
material rentals, royalties, and other amounts due and payable in respect thereof have been duly
paid. Without regard to any consent or non-consent provisions of any joint operating agreement
covering any of the Loan Parties’ Proved Reserves, and with the exception of Immaterial Title
Deficiencies, the Loan Parties’ share of (a) the costs for each Engineered Oil and Gas Property is
not greater
than the decimal fraction set forth in the most recent Engineering Report, before and after
payout, as the case may be, and described therein by the respective designations “working
interests,” “WI,” “gross working interest,” “GWI,” or similar terms, and (b) production from,
allocated to, or attributed to each Engineered Oil and Gas Property is not less than the decimal
fraction set forth in the most recent Engineering Report, before and after payout, as the case may
be, and described therein by the designations “net revenue interest,” “NRI,” or similar terms.

67

 

Except to the extent constituting an Immaterial Title Deficiency, each well drilled in respect of
each Engineered Oil and Gas Property described in the Engineering Report (y) is capable of, and is
presently, producing Hydrocarbons in commercial quantities, and the applicable Loan Party is
currently receiving payments for its share of production, with no material funds in respect of any
thereof being presently held in suspense, other than any such funds being held in suspense pending
delivery of appropriate division orders and other usual and customary suspense accounts, and (z)
has been drilled, bottomed, completed, and operated in compliance in all material respects with all
applicable Laws and no such well which is currently producing hydrocarbons is subject to any
penalty in production by reason of such well having produced in excess of its allowable production.
To Borrower’s knowledge, there are no unrecorded assignments or conveyances affecting the
Engineered Oil and Gas Properties or any Loan Party’s interest therein that would result in the
Borrower or its Subsidiaries having a WI or NRI that is less than the WI/NRI set forth in the
Engineering Report, except the interests of Sierra Madera CO2 Pipeline LP and Symbol Energy Inc.,
which constitute Immaterial Title Deficiencies.

     (b) The Engineered Oil and Gas Properties (and all properties unitized therewith) are, in all
material respects, being (and, to the extent the same could materially and adversely affect the
ownership or operation of the Engineered Oil and Gas Properties after the date hereof, to the
applicable Loan Party’s knowledge, have in the past been) maintained, operated and developed in a
good and workmanlike manner, in accordance with prudent industry standards and in conformity with
all applicable Laws and in conformity with all oil, gas or other mineral leases and other contracts
and agreements forming a part of the Engineered Oil and Gas Property and in conformity with the
Permitted Encumbrances. No Engineered Oil and Gas Property is subject to having allowable
production after the date hereof reduced below the full and regular allowable (including the
maximum permissible tolerance) because of any overproduction (whether or not the same was
permissible at the time) prior to the date hereof and (ii) none of the wells located on the
Engineered Oil and Gas Properties (or properties unitized therewith) are or will be deviated from
the vertical more than the maximum permitted by applicable laws, regulations, rules and orders, and
such wells are bottomed under and producing from, with the well bores wholly within, the Engineered
Oil and Gas Properties (or, in the case of wells located on properties unitized therewith, such
unitized properties). There are no dry holes, or otherwise inactive wells, located on the
Engineered Oil and Gas Properties or on lands pooled or unitized therewith, except for wells that
have been properly plugged and abandoned or for which appropriate plugging and abandonment has been
scheduled. Each Loan Party has all material governmental licenses and permits reasonably necessary
or appropriate to own and operate its Engineered Oil and Gas Properties, and no Loan Party has
received notice in writing of any material violations in respect of any such licenses or permits.

     5.22 Sale of Production. Except (x) as of the Closing Date, as set forth in Schedule 5.22, or (y)
thereafter, as disclosed in writing to the Administrative Agent and the Lenders and reflected
in the most recent determination of the Borrowing Base, or (z) for matters that constitute
Immaterial Title Deficiencies:

     (a) No Engineered Oil and Gas Property is subject to any material contractual or other
arrangement (i) whereby payment for production is or can be deferred for a substantial period after
the month in which such production is delivered (in the case of oil, not in excess of 60 days, and
in the case of gas, not in excess of 90 days) or (ii) whereby payments are made to a Loan

68

 

Party
other than by checks, drafts, wire transfer advises or other similar writings, instruments or
communications for the immediate payment of money;

     (b) (i) No Engineered Oil and Gas Property is subject to any material contractual or other
arrangement for the sale, processing or transportation of production (or otherwise related to the
marketing of production) which cannot be canceled on 120 days’ (or less) notice and (ii) all
material contractual or other arrangements for the sale, processing or transportation of production
(or otherwise related to the marketing of production) are bona fide arm’s length transactions made
with third parties not affiliated with Loan Parties;

     (c) Each Loan Party is presently receiving a price for all production (other than gas used
for operations at a field location) from (or attributable to) each Engineered Oil and Gas Property
covered by a production sales contract or marketing contract that is computed in accordance with
the terms of such contract, and no Loan Party is having deliveries of production from such
Engineered Oil and Gas Property curtailed substantially below such property’s delivery capacity,
except for curtailments caused (i) by an act or event of force majeure, or (ii) by routine
maintenance requirements in the ordinary course of business;

     (d) No Loan Party, nor, to such Loan Party’s knowledge, any Loan Party’s predecessors in
title, has received prepayments (including payments for gas not taken pursuant to “take or pay” or
other similar arrangements) for any oil, gas or other hydrocarbons produced or to be produced from
any Engineered Oil and Gas Properties after the date hereof;

     (e) No Engineered Oil and Gas Property is subject to any “take or pay” or other similar
arrangement (i) which can be satisfied in whole or in part by the production or transportation of
gas from other properties or (ii) as a result of which production from any Engineered Oil and Gas
Property may be required to be delivered to one or more third parties without payment (or without
full payment) therefor as a result of payments made, or other actions taken, with respect to other
properties;

     (f) There is no Engineered Oil and Gas Property with respect to which any Loan Party, or, to
such Loan Party’s knowledge, any Loan Party’s predecessors in title, has, prior to the date hereof,
taken more (“overproduced”), or less (“underproduced”), in any material respect, gas from the lands
covered thereby (or pooled or unitized therewith) than its ownership interest in such Engineered
Oil and Gas Property would entitle it to take; and as of the Closing Date Schedule 5.22
accurately reflects, in all material respects, for each well or unit with respect to which such an
imbalance is shown thereon to exist, (i) whether such Loan Party is overproduced or underproduced
and (ii) the volumes (in cubic feet or British thermal units) of such overproduction or
underproduction and the effective date of such information;

     (g) No Engineered Oil and Gas Property is subject to a gas balancing arrangement under which
one or more third parties may take a portion of the production attributable to such Engineered Oil
and Gas Property without payment (or without full payment) therefor as a result
of production having been taken from, or as a result of other actions or inactions with
respect to, other properties; and

     (h) No Engineered Oil and Gas Property is subject at the present time to any regulatory
refund obligation and, to such Loan Party’s knowledge, no facts exist which might cause the same to
be imposed.

     So long as any Lender shall have any Commitment hereunder, any Loan or other Obligation
hereunder shall remain unpaid or unsatisfied, or any Letter of Credit shall remain outstanding, the
Borrower shall, and shall (except in the case of the covenants set forth in Sections 6.01,
6.02, and 6.03) cause each Subsidiary to:

     6.01 Financial Statements. Deliver to the Administrative Agent and the Lenders as contemplated by

such fiscal year, and the related consolidated and consolidating statements of income or
operations, shareholders’ equity and cash flows for such fiscal year, setting forth in each case in
comparative form the figures for the previous fiscal year, all in reasonable detail and prepared in
accordance with GAAP, such consolidated statements to be audited and accompanied by a report and
opinion of a Registered Public Accounting Firm of nationally recognized standing, which report and
opinion shall be prepared in accordance with generally accepted auditing standards and applicable
Securities Laws and shall not be subject to any “going concern” or like qualification or exception
or any qualification or exception as to the scope of such audit or with respect to the absence of
any material misstatement and (ii) commencing at such time as the Borrower is required to prepare
the same for SEC reporting purposes, an opinion of such Registered Public Accounting Firm
independently assessing the Borrower’s internal controls over financial reporting in accordance
with Item 308 of the SEC Regulation S-K, PCAOB Auditing Standard No. 2, and Section 404 of
Sarbanes-Oxley expressing a conclusion that contains no statement that there is a material weakness
in such internal controls, except for such material weaknesses as to which the Required Lenders do
not object, and such consolidating statements to be certified by the chief executive officer, chief
financial officer, treasurer or controller of the Borrower to the effect that such statements are
fairly stated in all material respects when considered in relation to the consolidated financial
statements of the Borrower and its Subsidiaries;

     (b) as soon as available, but in any event within 45 days after the end of each of the first
three fiscal quarters of each fiscal year of the Borrower, a consolidated balance sheet of the
Borrower and its Subsidiaries as at the end of such fiscal quarter, and the related consolidated

As to any information contained in materials furnished pursuant to Section 6.02(d), the
Borrower shall not be separately required to furnish such information under clause (a) or (b)
above, but the foregoing shall not be in derogation of the obligation of the Borrower to furnish
the information and materials described in clauses (a) and (b) above at the times specified
therein.

     6.02 Certificates; Other Information. Deliver to the Administrative Agent and the Lenders as

Section 6.02(d) (to the extent any such documents are included in materials otherwise filed
with the SEC) may be delivered electronically and if so delivered, shall be deemed to have been
delivered on the

72

 

date (i) on which the Borrower posts such documents, or provides a link thereto on
the Borrower’s website on the Internet at the website address listed on Schedule 10.02; or
(ii) on which such documents are posted on the Borrower’s behalf on an Internet or intranet
website, if any, to which each Lender and the Administrative Agent have access (whether a
commercial, third-party website or whether sponsored by the Administrative Agent); provided
that: (i) the Borrower shall deliver paper copies of such documents to the Administrative Agent or
any Lender that requests the Borrower to deliver such paper copies until a written request to cease
delivering paper copies is given by the Administrative Agent or such Lender and (ii) the Borrower
shall notify the Administrative Agent and each Lender (by telecopier or electronic mail) of the
posting of any such documents and provide to the Administrative Agent by electronic mail electronic
versions (i.e., soft copies) of such documents. Notwithstanding anything contained herein,
in every instance the Borrower shall be required to provide paper copies of the Compliance
Certificates required by Section 6.02(b) to the Administrative Agent. Except for such
Compliance Certificates, the Administrative Agent shall have no obligation to request the delivery
or to maintain copies of the documents referred to above, and in any event shall have no
responsibility to monitor compliance by the Borrower with any such request for delivery, and each
Lender shall be solely responsible for requesting delivery to it or maintaining its copies of such
documents.

     The Borrower hereby acknowledges that (a) the Administrative Agent and/or the Arranger will
make available to the Lenders and the L/C Issuer materials and/or information provided by or on
behalf of the Borrower hereunder (collectively, “Borrower Materials”) by posting the
Borrower Materials on IntraLinks or another similar electronic system (the “Platform”) and
(b) certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to receive
material non-public information with respect to the Borrower or its securities) (each, a
“Public Lender”). The Borrower hereby agrees that so long as the Borrower is the issuer of
any outstanding debt or equity securities that are registered or issued pursuant to a private
offering or is actively contemplating issuing any such securities (w) all Borrower Materials that
are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC”
which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page
thereof; (x) by marking Borrower Materials “PUBLIC,” the Borrower shall be deemed to have
authorized the Administrative Agent, the Arranger, the L/C Issuer and the Lenders to treat such
Borrower Materials as not containing any material non-public information with respect to the
Borrower or its securities for purposes of United States Federal and state securities laws
(provided, however, that to the extent such Borrower Materials constitute
Information, they shall be treated as set forth in Section 10.07); (y) all Borrower
Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform
designated “Public Investor;” and (z) the Administrative Agent and the Arranger shall be entitled
to treat any Borrower
Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the
Platform not designated “Public Investor.”

     Each Public Lender shall designate individuals or advisors authorized to act on behalf of the
Public Lender to receive Borrower Materials not designated as “PUBLIC” pursuant to the immediately
preceding paragraph, including any notices pursuant to Section 6.03.

     6.03 Notices. Promptly notify the Administrative Agent and each Lender:

73

 

     (a) of the occurrence of any Default;

     (b) of any matter that has resulted or could reasonably be expected to result in a Material
Adverse Effect, including (i) breach or non-performance of, or any default under, a Contractual
Obligation of the Borrower or any Subsidiary; (ii) any dispute, litigation, investigation,
proceeding or suspension between the Borrower or any Subsidiary and any Governmental Authority; or
(iii) the commencement of, or any material development in, any litigation or proceeding affecting
the Borrower or any Subsidiary, including pursuant to any applicable Environmental Laws;

     (c) of the occurrence of any ERISA Event;

     (d) of any material change in accounting policies or financial reporting practices by the
Borrower or any Subsidiary;

preparation of such opinion) or the Borrower’s determination at any time of the occurrence or
existence of any Internal Control Event; and

     (f) of the (i) occurrence of any Disposition of property or assets for which the Borrower is
required to make a mandatory prepayment pursuant to Section 2.06(b)(ii), and (ii)
incurrence or issuance of any Indebtedness for which the Borrower is required to make a mandatory
prepayment pursuant to Section 2.06(b)(iii).

     Each notice pursuant to this Section 6.03 (other than Section 6.03(f)) shall
be accompanied by a statement of a Responsible Officer of the Borrower setting forth details of the
occurrence referred to therein and stating what action the Borrower has taken and proposes to take
with respect thereto. Each notice pursuant to Section 6.03(a) shall describe with
particularity any and all provisions of this Agreement and any other Loan Document that have been
breached.

     6.04 Payment of Obligations. Pay and discharge as the same shall become due and payable, (a) all
tax liabilities, assessments and governmental charges or levies upon it or its properties or
assets, unless the same are being contested in good faith by appropriate proceedings diligently
conducted and adequate reserves in accordance with GAAP are being maintained by the Borrower or
such Subsidiary; (b) all lawful claims which, if unpaid, would by law become a Lien
upon its property, except, in the case of (a) or (b), for such amounts that, individually or
in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

     6.05 Preservation of Existence, Etc. (a) Preserve, renew and maintain in full force and effect its
legal existence and good standing under the Laws of the jurisdiction of its organization except in
a transaction permitted by Section 7.04 or 7.05; (b) take all reasonable action to
maintain all rights, privileges, permits, licenses and franchises necessary or desirable in the
normal conduct of its business, except to the extent that failure to do so could not reasonably be
expected to have a Material Adverse Effect; and (c) preserve or renew all of its registered
patents, trademarks, trade names and service marks, the non-preservation of which could reasonably
be expected to have a Material Adverse Effect.

74

 

     6.06 Maintenance of Properties. (a) Maintain, preserve and protect all of its material properties
and equipment necessary in the operation of its business in good working order and condition,
ordinary wear and tear excepted; (b) make all necessary repairs thereto and renewals and

Material Adverse Effect; and (c) use the standard of care typical in the industry in the operation
and maintenance of its facilities.

     6.07 Maintenance of Insurance. (a) Maintain (at its own expense) insurance for its property in
accordance with the Insurance Schedule with financially sound and reputable insurance companies, as
well as insurance in such amounts, with such limitations or deductibles, against such risks, and in
such form as are customarily maintained by companies of established repute engaged in the same or
similar businesses operating in the same or similar locations. All insurance policies covering
Collateral shall be endorsed (i) to provide for payment of losses to the Administrative Agent as
its interests may appear, (ii) to provide that such policies may not be canceled or reduced or
affected in any material manner for any reason without ten (10) days prior notice to the
Administrative Agent, and (iii) to provide for any other matters specified in any applicable
Collateral Document. Each Loan Party shall at all times maintain insurance against its liability
for injury to persons or property in accordance with the Insurance Schedule, which insurance shall
be by financially sound and reputable insurers.

     (b) Reimbursement under any liability insurance maintained by Loan Parties pursuant to this
Section 6.07 may be paid directly to the Person who has incurred the liability covered by such
insurance. With respect to any loss involving damage to Collateral, each Loan Party will make or
cause to be made the necessary repairs to or replacements of such Collateral, and any proceeds of
insurance maintained by each Loan Party pursuant to this Section 6.07 shall be paid to such Loan
Party by the Administrative Agent as reimbursement for the costs of such repairs or replacements as
such repairs or replacements are made or acquired; provided that Administrative Agent shall be
entitled (but not obligated) to retain and apply such proceeds as Collateral during the continuance
of any Event of Default.

     6.08 Compliance with Laws. Comply in all material respects with the requirements of all Laws and

provided, however, that when an Event of Default exists the Administrative Agent or

the foregoing at the expense of the Borrower at any time during normal business hours and without
advance notice.

not already done so) to take whatever action (including the recording of mortgages, the filing of
Uniform Commercial Code financing statements, the giving of notices and the endorsement of notices
on title documents) may be necessary or advisable in the opinion of the Administrative Agent to
vest in the Administrative Agent (or in any representative of the Administrative Agent designated
by it) valid and subsisting Liens on the properties purported to be subject to the deeds of trust,

     (b) At all times the Obligations shall be secured by Liens covering and encumbering at least
80% of the total Attributed Value of the Proved Reserves attributable to the Engineered Oil and Gas

of the Administrative Agent to effect the foregoing, within 30 days after the delivery of each
Engineering Report, the Loan Parties that own Engineered Oil and Gas Properties shall execute and
deliver (i) mortgages and deeds of trust in form and substance acceptable to the Administrative

clean up all Hazardous Materials from any of its properties, in accordance in all material respects
with the requirements of all applicable Environmental Laws; provided, however, that
neither the Borrower nor any of its Subsidiaries shall be required to undertake any such cleanup,
removal, remedial or other action to the extent that its obligation to do so is not required by
applicable Environmental Laws or being contested in good faith and by proper proceedings and
appropriate reserves are being maintained with respect to such circumstances in accordance with
GAAP.

     6.14 Further Assurances. Promptly upon request by the Administrative Agent, or any Lender
through the Administrative Agent, (a) correct any material defect or error that may

77

 

be discovered in any Loan Document or in the execution, acknowledgment, filing or recordation thereof, and (b)
do, execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register any
and all such further acts, deeds, certificates, assurances and other instruments as the
Administrative Agent, or any Lender through the Administrative Agent, may reasonably require from
time to time in order to (i) to the fullest extent permitted by applicable law, subject any Loan
Party’s or any of its Subsidiaries’ properties, assets, rights or interests to the Liens now or
hereafter intended to be covered by any of the Collateral Documents, (ii) perfect and maintain the
validity, effectiveness and priority of any of the Collateral Documents and any of the Liens

Subsidiaries is or is to be a party, and cause each of its Subsidiaries to do so.

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

to make L/C Credit Extensions to be terminated, whereupon such commitments and obligation shall be
terminated;

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

     (c) require that the Borrower Cash Collateralize the L/C Obligations (in an amount equal to
the then Outstanding Amount thereof); and

     (d) exercise on behalf of itself, the Lenders and the L/C Issuer all rights and remedies
available to it, the Lenders and the L/C Issuer under the Loan Documents;

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

     8.03 Application of Funds. After the exercise of remedies provided for in Section 8.02 (or
after the Loans have automatically become immediately due and payable and the L/C Obligations have
automatically been required to be Cash Collateralized as set forth in the proviso to Section

expenses and other amounts (including fees, charges and disbursements of counsel to the
Administrative Agent and amounts payable under Article III) payable to the Administrative
Agent in its capacity as such;

     Second, to payment of that portion of the Obligations constituting fees, indemnities
and other amounts (other than principal, interest and Letter of Credit Fees) payable to the Lenders

among them in proportion to the respective amounts described in this clause Second
payable to them;

88

 

     Third, to payment of that portion of the Obligations constituting accrued and unpaid
Letter of Credit Fees and interest on the Loans, L/C Borrowings and other Obligations, ratably
among the Lenders and the L/C Issuer in proportion to the respective amounts described in this
clause Third payable to them;

     Fourth, to payment of that portion of the Obligations constituting unpaid principal of
the Loans and L/C Borrowings and amounts payable under Swap Contracts, ratably among the Lenders,
the L/C Issuer and the Lender Counterparties in proportion to the respective amounts described in
this clause Fourth held by them;

     Fifth, to the Administrative Agent for the account of the L/C Issuer, to Cash
Collateralize that portion of L/C Obligations comprised of the aggregate undrawn amount of Letters
of Credit; and

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

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate undrawn amount
of Letters of Credit pursuant to clause Fifth above shall be applied to satisfy drawings
under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral
after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be
applied to the other Obligations, if any, in the order set forth above.

ARTICLE IX.

ADMINISTRATIVE AGENT

     9.01 Appointment and Authority.

     (a) Each of the Lenders and the L/C Issuer hereby irrevocably appoints Bank of America to act
on its behalf as the Administrative Agent hereunder and under the other Loan Documents and
authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers
as are delegated to the Administrative Agent by the terms hereof or thereof, together with such
actions and powers as are reasonably incidental thereto. Except to the extent Sections 9.01(b) and
9.06 expressly contemplate rights of others, the provisions of this Article are solely for the
benefit of the Administrative Agent, the Lenders and the L/C Issuer, and the Borrower shall not
have rights as a third party beneficiary of any of such provisions.

     (b) The Administrative Agent shall also act as the “collateral agent” under the Loan
Documents, and each of the Lenders (in its capacities as a Lender and potential Lender
Counterparty) and the L/C Issuer hereby irrevocably appoints and authorizes the Administrative
Agent to act as the agent of such Lender and the L/C Issuer for purposes of acquiring, holding and
enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the
Obligations, together with such powers and discretion as are reasonably incidental thereto. In
this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents
and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 9.05
for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted
under the Collateral Documents, or for exercising any rights and remedies thereunder at the

89

 

direction of the Administrative Agent), shall be entitled to the benefits of all provisions of this
Article IX and Article X (including Section 10.04(c), as though such
co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents)
as if set forth in full herein with respect thereto.

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

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

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

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

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

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

     The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire
into (i) any statement, warranty or representation made in or in connection with this

90

 

Agreement or
any other Loan Document, (ii) the contents of any certificate, report or other document delivered
hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance
of any of the covenants, agreements or other terms or conditions set forth herein or therein or the
occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Loan Document or any other agreement, instrument or document or the creation,
perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the
value or the sufficiency of any Collateral, or (vi) the satisfaction of any condition set forth in
Article IV or elsewhere herein, other than to confirm receipt of items expressly required
to be delivered to the Administrative Agent.

     9.04 Reliance by Administrative Agent.

     The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument, document or other
writing (including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated
by the proper Person. The Administrative Agent also may rely upon any statement made to it orally
or by telephone and believed by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. In determining compliance with any condition hereunder to the
making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the
satisfaction of a Lender or the L/C Issuer, the Administrative Agent may presume that such
condition is satisfactory to such Lender or the L/C Issuer unless the Administrative Agent shall
have received notice to the contrary from such Lender or the L/C Issuer prior to the making of such
Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal
counsel (who may be counsel for the Borrower), independent accountants and other experts selected
by it, and shall not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountants or experts.

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

     9.06
Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders, the
L/C Issuer and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders
shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a
bank with an office in the United States, or an Affiliate of any such bank with an office in the
United States. If no such successor shall have been so appointed by the Required Lenders and shall
have accepted such appointment within 30 days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the L/C
Issuer, appoint a successor Administrative Agent meeting the qualifications set forth above;
provided that if the Administrative Agent shall notify the Borrower and the Lenders that no
qualifying Person has

91

 

accepted such appointment, then such resignation shall nonetheless become
effective in accordance with such notice and (1) the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder and under the other Loan Documents (except
that in the case of any collateral security held by the Administrative Agent on behalf of the
Lenders or the L/C Issuer under any of the Loan Documents, the retiring Administrative Agent shall
continue to hold such collateral security until such time as a successor Administrative Agent is
appointed) and (2) all payments, communications and determinations provided to be made by, to or
through the Administrative Agent shall instead be made by or to each Lender and the L/C Issuer
directly, until such time as the Required Lenders appoint a successor Administrative Agent as
provided for above in this Section. Upon the acceptance of a successor’s appointment as
Administrative Agent hereunder, such successor shall succeed to and become vested with all of the
rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the
retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder
or under the other Loan Documents (if not already discharged therefrom as provided above in this
Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same
as those payable to its predecessor unless otherwise agreed between the Borrower and such
successor. After the retiring Administrative Agent’s resignation hereunder and under the other
Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect
for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them while the retiring
Administrative Agent was acting as Administrative Agent.

     Any resignation by Bank of America as Administrative Agent pursuant to this Section shall also
constitute its resignation as L/C Issuer and Swing Line Lender. Upon the acceptance of a
successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and
become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer and
Swing Line Lender, (b) the retiring L/C Issuer and Swing Line Lender shall be discharged from all
of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the
successor L/C Issuer 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 L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect
to such Letters of Credit.

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

     9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, the Arranger
shall have no powers, duties or responsibilities under this Agreement.

92

 

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

     (a) to file and prove a claim for the whole amount of the principal and interest owing
and unpaid in respect of the Loans, L/C 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 Lenders, the L/C Issuer and the Administrative Agent (including any
claim for the reasonable compensation, expenses, disbursements and advances of the Lenders,
the L/C Issuer and the Administrative Agent and their respective agents and counsel and all
other amounts due the Lenders, the L/C Issuer and the Administrative Agent under
Sections 2.03(i) and (j), 2.09 and 10.04) allowed in such
judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such
payments to the Administrative Agent and, in the event that the Administrative Agent shall consent
to the making of such payments directly to the Lenders and the L/C Issuer, to pay to the
Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and
advances of the Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.09 and 10.04.

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

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

     (a) to release any Lien on any property granted to or held by the Administrative Agent
under any Loan Document (i) upon termination of the Aggregate Commitments and payment in
full of all Obligations (other than contingent indemnification obligations and obligations
with respect to Swap Contracts) and the expiration or termination of all Letters of Credit,
(ii) that is Disposed of or to be Disposed of as part of or in connection with any
Disposition permitted hereunder or under any other Loan Document, or (iii) subject to
Section 10.01, if approved, authorized or ratified in writing by the Required
Lenders;

93

 

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

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

     Upon request by the Administrative Agent at any time, the Required Lenders will confirm in
writing the Administrative Agent’s authority to release or subordinate its interest in particular
types or items of property, or to release any Guarantor from its obligations under the Guaranty
pursuant to this Section 9.10. In each case as specified in this Section 9.10, the
Administrative Agent will, at the Borrower’s expense, execute and deliver to the applicable Loan
Party such documents as such Loan Party may reasonably request to evidence the release of such item
of Collateral from the assignment and security interest granted under the Collateral Documents or
to subordinate its interest in such item, or to release such Guarantor from its obligations under
the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section
9.10.

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

     (c) The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT
PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE 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 ANY AGENT PARTY IN CONNECTION WITH THE
BORROWER MATERIALS OR THE PLATFORM. In no event shall the Administrative Agent or any of its
Related Parties (collectively, the “Agent Parties”) have any liability to the Borrower, any
Lender, the L/C Issuer 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
Administrative 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 such Agent Party; provided, however, that in no
event shall any Agent Party have any liability to the Borrower, any Lender, the L/C Issuer or any
other Person for indirect, special, incidental, consequential or punitive damages (as opposed to
direct or actual damages).

96

 

     (d) Change of Address, Etc. Each of the Borrower, the Administrative Agent, the L/C
Issuer and the Swing Line Lender may change its address, telecopier or telephone number for notices
and other communications hereunder by notice to the other parties hereto. Each other Lender may
change its address, telecopier or telephone number for notices and other communications hereunder
by notice to the Borrower, the Administrative Agent and the L/C Issuer and the Swing Line Lender.
In addition, each Lender agrees to notify the Administrative Agent from time to time to ensure that
the Administrative Agent has on record (i) an effective address, contact name, telephone number,
telecopier number and electronic mail address to which notices and other communications may be sent
and (ii) accurate wire instructions for such Lender.

     (e) Reliance by Administrative Agent, L/C Issuer and Lenders. The Administrative
Agent, the L/C Issuer and the Lenders shall be entitled to rely and act upon any notices (including
telephonic Committed Loan Notices and Swing Line Loan Notices) 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 other form of notice specified herein, or (ii) the terms
thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall
indemnify the Administrative Agent, the L/C Issuer, each Lender and the Related Parties of each of
them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on
each notice purportedly given by or on behalf of the Borrower. All telephonic notices to and other
telephonic communications with the Administrative Agent may be recorded by the Administrative
Agent, and each of the parties hereto hereby consents to such recording.

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

     10.04 Expenses; Indemnity; Damage Waiver.

     (a) Costs and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket
expenses incurred by the Administrative Agent and its Affiliates (including the reasonable fees,
charges and disbursements of counsel for the Administrative Agent), in connection with the
syndication of the credit facilities provided for herein, the preparation, negotiation, execution,
delivery and administration of this Agreement and the other Loan Documents or any amendments,
modifications or waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses
incurred by the L/C Issuer in connection with the issuance, amendment, renewal or extension of any
Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred
by the Administrative Agent, any Lender or the L/C Issuer (including the fees, charges and
disbursements of any counsel for the Administrative Agent, any Lender or the L/C Issuer), and shall
pay all fees and time charges for attorneys who may be employees of the Administrative Agent, any
Lender or the L/C Issuer, in connection with the

97

 

enforcement or protection of its rights (A) in
connection with this Agreement and the other Loan Documents, including its rights under this
Section, or (B) in connection with the Loans made or Letters of Credit issued hereunder, including
all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in
respect of such Loans or Letters of Credit.

     (b) Indemnification by the Borrower. The Borrower shall indemnify the Administrative
Agent (and any sub-agent thereof), each Lender and the L/C Issuer, and each Related Party of any of
the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold
each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related
expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and
shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements
for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted
against any Indemnitee by any third party or by the Borrower or any other Loan Party arising out
of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any
other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance
by the parties hereto of their respective obligations hereunder or thereunder, the consummation of
the transactions contemplated hereby or thereby, or, in the case of the Administrative Agent (and
any sub-agent thereof) and its Related Parties only, the administration of this Agreement and the
other Loan Documents, (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds
therefrom (including any refusal by the L/C Issuer 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), (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or
any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv)
any actual or prospective claim, litigation, investigation or proceeding relating to any of the
foregoing, whether based on contract, tort or any other theory, whether brought by a third party or
by the Borrower or any other Loan Party, and regardless of whether any Indemnitee is a party
thereto, in all cases, whether or not caused by or arising, in whole or in part, out of the
comparative, contributory or sole negligence of the Indemnitee; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by
final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from
a claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in bad
faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower
or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as
determined by a court of competent jurisdiction.

     (c) Reimbursement by Lenders. To the extent that the Borrower for any reason fails to
indefeasibly pay any amount required under subsection (a) or (b) of this Section to be paid by it
to the Administrative Agent (or any sub-agent thereof), the L/C Issuer or any Related Party of any
of the foregoing, each Lender severally agrees to pay to the Administrative Agent (or any such
sub-agent), the L/C Issuer or such Related Party, as the case may be, such Lender’s Applicable
Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment
is sought) of such unpaid amount, provided that the unreimbursed expense or indemnified
loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted
against the Administrative Agent (or any such sub-agent) or the L/C Issuer in its

98

 

capacity as such,
or against any Related Party of any of the foregoing acting for the Administrative Agent (or any
such sub-agent) or L/C Issuer in connection with such capacity. The obligations of the Lenders
under this subsection (c) are subject to the provisions of Section 2.13(d).

     (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee,
on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to
direct or actual damages) arising out of, in connection with, or as a result of, this Agreement,
any other Loan Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof.
No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the
use by unintended recipients of any information or other materials distributed to such unintended
recipients by such Indemnitee through telecommunications, electronic or other information
transmission systems in connection with this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby other than for direct or actual damages resulting from
the gross negligence or willful misconduct of such Indemnitee as determined by a final and
nonappealable judgment of a court of competent jurisdiction.

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

     (f) Survival. The agreements in this Section shall survive the resignation of the
Administrative Agent, the L/C Issuer and the Swing Line Lender, the replacement of any Lender, the
termination of the Aggregate Commitments and the repayment, satisfaction or discharge of all the
other Obligations.

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

99

 

     10.06 Successors and Assigns.

     (a) Successors and Assigns Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its
rights or obligations hereunder without the prior written consent of the Administrative Agent and
each Lender and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an 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, (iii) by way of pledge or assignment of a security interest subject to the restrictions of
subsection (f) of this Section, or (iv) to an SPC in accordance with the provisions of subsection
(h) of this Section (and any other attempted assignment or transfer by any party hereto shall be
null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon
any Person (other than the parties hereto, their respective successors and assigns permitted
hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent
expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the L/C
Issuer and the Lenders) any legal or equitable right, remedy or claim under or by reason of this
Agreement.

     (b) Assignments by Lenders. Any Lender may at any time assign to one or more
assignees all or a portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans (including for purposes of this subsection (b),
participations in L/C Obligations and in Swing Line Loans) at the time owing to it);
provided that any such assignment shall be subject to the following conditions:

     (i) Minimum Amounts.

     (A) in the case of an assignment of the entire remaining amount of the
assigning Lender’s Commitment and the Loans at the time owing to it or in the case
of an assignment to a Lender, an Affiliate of a Lender 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 Loans
outstanding thereunder) or, if the Commitment is not then in effect, the principal
outstanding balance of the Loans of the assigning Lender subject to each such
assignment, determined as of the date the Assignment and Assumption with respect to
such assignment is delivered to the Administrative Agent or, if “Trade Date” is
specified in the Assignment and Assumption, as of the Trade Date, shall not be less
than $5,000,000 unless each of the Administrative Agent and, so long as no Event of
Default has occurred and is continuing, the Borrower otherwise consents (each such
consent not to be unreasonably withheld or delayed); provided,
however, that concurrent assignments to members of an Assignee Group and
concurrent assignments from members of an Assignee Group to a single assignee (or to
an 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..

100

 

     (ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender’s rights and obligations
under this Agreement with respect to the Loans or the Commitment assigned, except that this
clause (ii) shall not apply to the Swing Line Lender’s rights and obligations in respect of
Swing Line Loans;

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

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

     (C) the consent of the L/C Issuer and the Swing Line Lender (such consent not
to be unreasonably withheld or delayed) shall be required for any assignment.

     (iv) Assignment and Assumption. The parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee in the amount, if any, required as set forth in Schedule
10.06; provided, however, that the Administrative Agent may, in its sole
discretion, elect to waive such processing and recordation fee in the case of any
assignment. The assignee, if it is not a Lender, shall deliver to the Administrative 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 Administrative Agent pursuant to subsection (c)
of this Section, from and after the effective date specified in each Assignment and Assumption, the
assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04
with respect to facts and circumstances occurring prior to the effective date of such assignment.
Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee

101

 

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

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

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

     Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, waiver or other modification described in the first proviso to
Section 10.01 that affects such Participant. Subject to subsection (e) of this Section,
the Borrower agrees that each Participant shall be entitled to the benefits of Sections
3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired
its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.08 as though it
were a Lender, provided such Participant agrees to be subject to Section 2.14 as
though it were a Lender.

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

102

 

such Participant agrees, for the benefit of the Borrower, to comply with Section
3.01(e) as though it were a Lender.

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

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

     (h) Special Purpose Funding Vehicles. Notwithstanding anything to the contrary
contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding
vehicle identified as such in writing from time to time by the Granting Lender to the
Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of
any Committed Loan that such Granting Lender would otherwise be obligated to make pursuant to this
Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to
fund any Committed Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails
to make all or any part of such Committed Loan, the Granting Lender shall be obligated to make such
Committed Loan pursuant to the terms hereof or, if it fails to do so, to make such payment to the
Administrative Agent as is required under Section 2.13(b)(ii). Each party hereto hereby
agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall
increase the costs or expenses or otherwise increase or change the obligations of the Borrower
under this Agreement (including its obligations under Section 3.04), (ii) no SPC shall be
liable for any indemnity or similar payment obligation under this Agreement for which a Lender
would be liable, and (iii) the Granting Lender shall for all purposes, including the approval of
any amendment, waiver or other modification of any provision of any Loan Document, remain the
lender of record hereunder. The making of a Committed Loan by an SPC hereunder shall utilize the
Commitment of the Granting Lender to the same extent, and as if, such Committed Loan were made by
such Granting Lender. In furtherance of the foregoing, each party hereto hereby agrees (which
agreement shall survive the termination of this Agreement) that, prior to the date that is one year
and one day after the payment in full of all outstanding commercial paper or other senior debt of
any SPC, it will not institute against, or join any other Person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws
of the United States or any State thereof. Notwithstanding anything to the contrary contained
herein, any SPC may (i) with notice to, but without prior consent of the Borrower and the
Administrative Agent and with the payment of a processing fee in the amount of $2,500, assign all
or any portion of its right to receive payment with respect to any Committed Loan to the Granting
Lender and (ii) disclose on a confidential basis any non-public information

103

 

relating to its funding of Committed Loans to any rating agency, commercial paper dealer or
provider of any surety or Guarantee or credit or liquidity enhancement to such SPC.

     (i) Resignation as L/C Issuer or Swing Line Lender after Assignment. Notwithstanding
anything to the contrary contained herein, if at any time Bank of America assigns all of its
Commitment and Loans pursuant to subsection (b) above, Bank of America may, (i) upon 30 days’
notice to the Borrower and the Lenders, resign as L/C Issuer and/or (ii) upon 30 days’ notice to
the Borrower, resign as Swing Line Lender.. In the event of any such resignation as L/C Issuer or
Swing Line Lender, the Borrower shall be entitled to appoint from among the Lenders a successor L/C
Issuer or Swing Line Lender hereunder; provided, however, that no failure by the
Borrower to appoint any such successor shall affect the resignation of Bank of America as L/C
Issuer or Swing Line Lender, as the case may be. If Bank of America resigns as L/C Issuer, it
shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder with respect
to all Letters of Credit outstanding as of the effective date of its resignation as L/C Issuer and
all L/C Obligations with respect thereto (including the right to require the Lenders to make Base
Rate Committed Loans or fund risk participations in Unreimbursed Amounts pursuant to Section
2.03(c)). If Bank of America resigns as Swing Line Lender, it shall retain all the rights of
the Swing Line Lender provided for hereunder with respect to Swing Line Loans made by it and
outstanding as of the effective date of such resignation, including the right to require the
Lenders to make Base Rate Committed Loans or fund risk participations in outstanding Swing Line
Loans pursuant to Section 2.04(c). Upon the appointment of a successor L/C Issuer and/or
Swing Line Lender, (a) such successor shall succeed to and become vested with all of the rights,
powers, privileges and duties of the retiring L/C Issuer or Swing Line Lender, as the case may be,
and (b) the successor L/C Issuer 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.

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

104

 

(y) becomes available to the Administrative Agent, any Lender, the L/C Issuer 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 Administrative Agent, any
Lender or the L/C Issuer 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
nonpublic and 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 confidential information of a similar nature.

     Each of the Administrative Agent, the Lenders and the L/C Issuer 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 Law, including Federal and state securities Laws.

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

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

105

 

voluntary prepayments and the
effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the
total amount of interest throughout the contemplated term of the Obligations hereunder.

     10.10
Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts
(and by different parties hereto in different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single contract. This Agreement
and the other Loan Documents constitute the entire contract among the parties relating to the
subject matter hereof and, except as otherwise expressly provided in the Commitment Letter,
supersede any and all previous agreements and understandings, oral or written, relating to the
subject matter hereof. Except as provided in Section 4.01, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when the Administrative
Agent shall have received counterparts hereof that, when taken together, bear the signatures of
each of the other parties hereto. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this
Agreement.

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

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

     10.13 Replacement of Lenders. If (i) any Lender requests compensation under Section
3.04, (ii) the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of
any Lender pursuant to Section 3.01, (iii) any Lender is a Defaulting Lender, or (iv)
any Lender is unwilling to approve an increase in the Borrowing Base or other amendment hereto
which has been approved by Super-Majority Lenders but requires approval of such Lender to be
effective, then the Borrower may, at its sole expense and effort, upon notice to such Lender and
the Administrative Agent, require such Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in, and consents required by, Section
10.06), all of its interests, rights and obligations under this

106

 

Agreement and the related Loan
Documents to an assignee that shall assume such obligations (which assignee may be another Lender,
if a Lender accepts such assignment), provided that:

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

     (b) such Lender shall have received payment of an amount equal to the outstanding principal of
its Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to
it hereunder and under the other Loan Documents (including any amounts under Section 3.05)
from the assignee (to the extent of such outstanding principal and accrued interest and fees) or
the Borrower (in the case of all other amounts);

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

     (d) in the case of an assignment resulting from clause (iv) above, such assignment will result
in effectiveness of such increase or amendment; and

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

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

     10.14 Governing Law; Jurisdiction; Etc.

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

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

107

 

THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY
JURISDICTION.

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

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

     10.15
Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR
THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER
PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES
HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     10.16 No Advisory or Fiduciary Responsibility.

     In connection with all aspects of each transaction contemplated hereby, the Borrower
acknowledges and agrees that: (i) the credit facility provided for hereunder and any related
arranging or other services in connection therewith (including in connection with any
amendment, waiver or other modification hereof or of any other Loan Document) are an
arm’s-length commercial transaction between the Borrower and its Affiliates, on the one hand, and
the Administrative Agent and the Arranger, on the other hand, and the Borrower is capable of
evaluating and understanding and understands and accepts the terms, risks and conditions of the
transactions contemplated hereby and by the other Loan Documents (including any amendment, waiver
or other modification hereof or thereof); (ii) in connection with the process leading to such
transaction, the Administrative Agent and the Arranger each is and has been acting solely as a
principal and is not the financial advisor, agent or fiduciary, for the Borrower or any of its

108

 

Affiliates, stockholders, creditors or employees or any other Person; (iii) neither the
Administrative Agent nor the Arranger has assumed or will assume an advisory, agency or fiduciary
responsibility in favor of the Borrower with respect to any of the transactions contemplated hereby
or the process leading thereto, including with respect to any amendment, waiver or other
modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent
or the Arranger has advised or is currently advising the Borrower or any of its Affiliates on other
matters) and neither the Administrative 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 Loan Documents; (iv) the Administrative
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 Administrative Agent nor the Arranger has any obligation to disclose any of such
interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Administrative
Agent and the Arranger have not provided and will not provide any legal, accounting, regulatory or
tax advice with respect to any of the transactions contemplated hereby (including any amendment,
waiver or other modification hereof or of any other Loan Document) and the Borrower has consulted
its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate.
The Borrower hereby waives and releases, to the fullest extent permitted by law, any claims that it
may have against the Administrative Agent and the Arranger with respect to any breach or alleged
breach of agency or fiduciary duty.

     10.17
USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined)
and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the
Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and
record information that identifies the Borrower, which information includes the name and address of
the Borrower and other information that will allow such Lender or the Administrative Agent, as
applicable, to identify the Borrower in accordance with the Act.

Lender of the amount of its ratable share of the applicable Loans, and if no timely notice of a
conversion or continuation is provided by the Borrower, the Administrative Agent shall notify each
Lender of the details of any automatic conversion to Base Rate Loans described in the preceding
subsection. In the case of the Borrowing, each Lender shall make the amount of its Loan available

     (ii) If any amount (other than principal of any Loan) payable by the Borrower under any Loan
Document is not paid when due (without regard to any applicable grace periods), whether at stated

     2.07 Computation of Interest and Fees. All computations of interest for Base Rate Loans when
the Base Rate is determined by Bank of America’s “prime rate” shall be made on the basis of a year
of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees
and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in

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

     2.09 Payments Generally; Administrative Agent’s Clawback.

     (a) General. All payments to be made by the Borrower shall be made without condition
or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly
provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent,
for the account of the respective Lenders to which such payment is owed, at the Administrative
Agent’s Office in Dollars and in immediately available funds not later than 2:00 p.m. on the date
specified herein. The Administrative Agent will promptly distribute to each Lender its ratable
share of such payment in like funds as received by wire transfer to such Lender’s Lending Office.
All payments received by the Administrative Agent after 2:00 p.m. shall be deemed received on the
next succeeding Business Day and any applicable interest or fee

28

 

shall continue to accrue. If any
payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall
be made on the next following Business Day, and such extension of time shall be reflected in
computing interest or fees, as the case may be.

     (b) (i) Funding by Lenders; Presumption by Administrative Agent. Unless the
Administrative Agent shall have received notice from a Lender prior to the Closing Date that such
Lender will not make available to the Administrative Agent such Lender’s share of the Borrowing,
the Administrative Agent may assume that such Lender has made such share available on such date in
accordance with Section 2.02 and may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of
the Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower
severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in
immediately available funds with interest thereon, for each day from and including the date such
amount is made available to the Borrower to but excluding the date of payment to the Administrative
Agent, at (A) in the case of a payment to be made by such Lender, the greater of the Federal Funds
Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on
interbank compensation, plus any administrative, processing or similar fees customarily charged by
the Administrative Agent in connection with the foregoing, and (B) in the case of a payment to be
made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such
Lender shall pay such interest to the Administrative Agent for the same or an overlapping period,
the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by
the Borrower for such period. If such Lender pays its share of the Borrowing to the Administrative
Agent, then the amount so paid shall constitute such Lender’s Loan included in the Borrowing. Any
payment by the Borrower shall be without prejudice to any claim the Borrower may have against a
Lender that shall have failed to make such payment to the Administrative Agent.

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

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

     (c) Failure to Satisfy Conditions Precedent. If any Lender makes available to the
Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing
provisions of this Article II, and such funds are not made available to the Borrower by the
Administrative Agent because the conditions to the Initial Loans set forth in Article IV
are

29

 

not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall
return such funds (in like funds as received from such Lender) to such Lender, without interest.

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

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

     2.10 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff
or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of
the Loans made by it resulting in such Lender’s receiving payment of a proportion of the aggregate
amount of such Loans and accrued interest thereon greater than its pro rata share
thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the
Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the
Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans and other amounts
owing them, provided that:

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

     (ii) the provisions of this Section shall not be construed to apply to (x) any payment
made by the Borrower pursuant to and in accordance with the express terms of this Agreement
or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans

     to any assignee or participant, other than to the Borrower or any Subsidiary thereof
(as to which the provisions of this Section shall apply).

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

30

 

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 Taxes.

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

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

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

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

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

31

 

applicable law or
reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the
Administrative Agent to determine whether or not such Lender is subject to backup withholding or
information reporting requirements.

     Without limiting the generality of the foregoing, in the event that the Borrower is resident
for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior
to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to
time thereafter upon the request of the Borrower or the Administrative Agent, but only if such
Foreign Lender is legally entitled to do so), whichever of the following is applicable:

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

     (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

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

     (iv) any other form prescribed by applicable law as a basis for claiming exemption from
or a reduction in United States Federal withholding tax duly completed together with such
supplementary documentation as may be prescribed by applicable law to permit the Borrower to
determine the withholding or deduction required to be made.

     (f) Treatment of Certain Refunds. If the Administrative Agent or any Lender
determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to
which it has been indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such
refund (but only to the extent of indemnity payments made, or additional amounts paid, by the
Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund),
net of all out-of-pocket expenses of the Administrative Agent or such Lender, as the case may be,
and without interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund), provided that the Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) to the
Administrative Agent or such Lender in the event the Administrative Agent or such Lender is
required to repay such refund to such Governmental Authority. This subsection shall not be
construed to require the Administrative Agent or any Lender to make available its tax returns (or
any other information relating to its taxes that it deems confidential) to the Borrower or any
other Person.

32

 

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

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

     3.04 Increased Costs; Reserves on Eurodollar Rate Loans.

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

     (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, any Lender (except any reserve requirement
contemplated by Section 3.04(e));

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

33

 

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

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

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

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

     (d) Delay in Requests. Failure or delay on the part of any Lender to demand
compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of
such Lender’s right to demand such compensation, provided that the Borrower shall not be
required to compensate a Lender pursuant to the foregoing provisions of this Section for any
increased costs incurred or reductions suffered more than 180 days prior to the date that such
Lender notifies the Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Lender’s intention to claim compensation therefor (except that, if the
Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month
period referred to above shall be extended to include the period of retroactive effect thereof).

     (e) Reserves on Eurodollar Rate Loans. The Borrower shall pay to each Lender, as long
as such Lender shall be required to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency funds or deposits (currently known as “Eurocurrency
liabilities”), additional interest on the unpaid principal amount of each Eurodollar Rate Loan
equal to the actual costs of such reserves allocated to such Loan by such Lender (as determined by
such Lender in good faith, which determination shall be conclusive), which shall be due and payable
on each date on which interest is payable on such Loan, provided the Borrower shall have received
at least 10 days’ prior notice (with a copy to the Administrative Agent) of such

34

 

additional interest from such Lender. If a Lender fails to give notice 10 days prior to the relevant Interest
Payment Date, such additional interest shall be due and payable 10 days from receipt of such
notice.

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

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

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

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

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

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

     3.06 Mitigation Obligations; Replacement of Lenders.

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

     (b) Replacement of Lenders. If any Lender requests compensation under Section
3.04, or if the Borrower is required to pay any additional amount to any Lender or any

35

 

Governmental Authority for the account of any Lender pursuant to Section 3.01, the Borrower
may replace such Lender in accordance with Section 10.13.

     3.07 Survival. All of the Borrower’s obligations under this Article III shall survive
termination of the Aggregate Commitments and repayment of all other Obligations hereunder.

ARTICLE V.

REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Administrative Agent and the Lenders that:

     5.01 Existence, Qualification and Power. Each Loan Party and each of its Subsidiaries (a) is
duly organized or formed, validly existing and, as applicable, in good standing under the Laws of
the jurisdiction of its incorporation or organization, (b) has all requisite power and authority
and all requisite governmental licenses, authorizations, consents and approvals to (i) own or lease
its assets and carry on its business and (ii) execute, deliver and perform its obligations under
the Loan Documents and (as of the Closing Date only) Related Documents to which it is a party and
consummate the Transaction, and (c) is duly qualified and is licensed and, as applicable, in
good standing under the Laws of each jurisdiction where its ownership, lease or operation of
properties or the conduct of its business requires such qualification or license; except in each
case referred to in clause (b)(i) or (c), to the extent that failure to do so could not reasonably
be expected to have a Material Adverse Effect.

     5.02 Authorization; No Contravention. The execution, delivery and performance by each Loan
Party of each Loan Document and (as of the Closing Date only) Related Document to which such Person
is or is to be a party have been duly authorized by all necessary corporate or other organizational
action, and do not and will not (a) contravene the terms of any of such Person’s Organization
Documents; (b) conflict with or result in any breach or contravention of, or the creation of any
Lien under, or require any payment to be made under (i) any Contractual Obligation that is material
to the Loan Parties to which such Person is a party or affecting such Person or the properties of
such Person or any of its Subsidiaries or (ii) any order, injunction, writ or decree of any
Governmental Authority or any arbitral award to which such Person or its property is subject; or
(c) violate any Law.

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

     The Borrower hereby acknowledges that (a) the Administrative Agent and/or the Arranger will
make available to the Lenders materials and/or information provided by or on behalf of the Borrower
hereunder (collectively, “Borrower Materials”) either by posting the Borrower Materials on
IntraLinks or another similar electronic system (the “Platform”) or by delivery or
electronic communication to the applicable Lenders and (b) certain of the Lenders may be
“public-side” Lenders (i.e., Lenders that do not wish to receive material non-public information
with respect to the Borrower or its securities except as contemplated below) (each, a
“Public-Side Lender”). The Borrower hereby agrees that so long as the Borrower is the
issuer of any outstanding debt or equity securities that are registered or issued pursuant to a
private offering or is actively contemplating issuing any such securities (x) all Borrower
Materials that are to be posted on the Platform shall be clearly and conspicuously marked
“PUBLIC-SIDE” which, at a minimum, shall mean that the words “PUBLIC-SIDE” shall appear prominently
on the first page thereof; (y) by marking Borrower Materials “PUBLIC-SIDE,” the Borrower shall be
deemed to have authorized the Administrative Agent, the Arrangers and the Lenders to treat
such Borrower Materials as not containing any material non-public information with respect to
the Borrower or its securities for purposes of United States Federal and state securities laws
(provided, however, that (A) prior to the creation of a Public Market, Lenders
shall treat such Borrower Materials as containing material non-public information with respect to
the Borrower and its Subsidiaries (“MNPI”), and the Borrower shall be deemed to have
represented to the Lenders that it expects such Borrower Materials will cease to be MNPI at the
time of creation of a Public Market and (B) to the extent such Borrower Materials constitute
Information, they shall be treated as set forth in Section 10.07); and (z) any Borrower
Materials that are not marked

47

 

“PUBLIC-SIDE” as contemplated above shall be treated as containing
MNPI, shall not be posted on the Platform and shall be available to Lenders only upon request
therefor (which request may apply generally to all such Borrower Materials). Any such request
shall constitute a confirmation from the applicable Lender that it has compliance procedures for
dealing with such MNPI, and that it will use and maintain such information only in compliance with
those procedures, its contractual obligations and applicable law, including federal and state
securities laws.

     Each Public-Side Lender shall designate individuals or advisors authorized to act on behalf of
the Public-Side Lender to receive Borrower Materials not designated as “PUBLIC-SIDE” pursuant to
the immediately preceding paragraph, including any notices pursuant to Section 6.03.

     6.03 Notices. Promptly notify the Administrative Agent and each Lender:

     (a) of the occurrence of any Default;

     (b) of any matter that has resulted or could reasonably be expected to result in a Material
Adverse Effect, including (i) breach or non-performance of, or any default under, a Contractual
Obligation of the Borrower or any Subsidiary; (ii) any dispute, litigation, investigation,
proceeding or suspension between the Borrower or any Subsidiary and any Governmental Authority; or

existence of any Internal Control Event; and

     (f) of the (i) occurrence of any Disposition of property or assets for which the Borrower is
required to make a mandatory prepayment pursuant to Section 2.03(b)(i), and (ii)
incurrence or issuance of any Indebtedness or Equity Interests for which the Borrower is
required to make a mandatory prepayment pursuant to Section 2.03(b)(ii).

     Each notice pursuant to this Section 6.03 (other than Section 6.03(f)) shall
be accompanied by a statement of a Responsible Officer of the Borrower setting forth details of the
occurrence referred to therein and stating what action the Borrower has taken and proposes to take
with respect thereto. Each notice pursuant to Section 6.03(a) shall describe with
particularity any and all provisions of this Agreement and any other Loan Document that have been
breached.

such Subsidiary; (b) all lawful claims which, if unpaid, would by law become a Lien upon its

prepayment (subject to the right of Lenders of record on a record date to receive interest on the
relevant Interest Payment Date) (the “Change of Control Payment”);

Change of Control Offer is conditional on the occurrence of such Change of Control.

               On the Change of Control Payment Date, if the Change of Control shall have occurred, the
Borrower will, to the extent lawful pay to the Administrative Agent for application to the
repayment of all Loans properly tendered pursuant to the Change of Control Offer an amount equal to
the Change of Control Payment in respect of all Loans so tendered.

               The Borrower will not be required to make a Change of Control Offer upon a Change of Control

such shelf registration statement to be declared effective by the Initial Maturity Date and keep
such shelf registration statement effective, with respect to resales of the Exchange Notes, for as
long as it is required by the holders to resell the Exchange Notes. Upon failure to comply with
the foregoing requirements (a “Registration Default”), the Borrower shall pay liquidated damages to
each holder of Exchange Notes with respect to the first 90-day period immediately following the
occurrence of the first Registration Default in an amount equal to one-half of one percent (0.50%)
per annum on the principal amount of Exchange Notes held by such holder. The amount of the
liquidated damages will increase by an additional one-half of one percent (0.50%) per annum on the

subsequent 90-day period until all Registration Defaults have been cured, up to a maximum
amount of liquidated damages for all Registration Defaults of 1.5% per annum.

Indebtedness or the beneficiary or beneficiaries of such Guarantee (or a trustee or agent on behalf
of such holder or holders or beneficiary or beneficiaries) to cause, with the giving of notice if
required, such Indebtedness to be demanded or to become due or to be repurchased, prepaid, defeased

more final judgments or orders for the payment of money in an aggregate amount (as to all such
judgments or orders) exceeding the Threshold Amount (to the extent not covered by independent
third-party insurance as to which the insurer does not dispute coverage), or (ii) any one or more
non-monetary final judgments that have, or could reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect and, in either case, (A) enforcement proceedings are

unpaid thereon, and all other amounts owing or payable hereunder or under any other Loan Document
to be immediately due and payable, without presentment, demand, protest or other notice of any
kind, all of which are hereby expressly waived by the Borrower; and

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

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

full, to the Borrower or as otherwise required by Law.

ARTICLE
IX.

ADMINISTRATIVE AGENT

     9.01Appointment and Authority.

     Each of the Lenders hereby irrevocably appoints Bank of America to act on its behalf as the
Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative
Agent to take such actions on its behalf and to exercise such powers as are delegated to the
Administrative Agent by the terms hereof or thereof, together with such actions and powers as are
reasonably incidental thereto. Except to the extent Sections 9.01(b) and 9.06 expressly
contemplate rights of others, the provisions of this Article are solely for the benefit of the
Administrative Agent and the Lenders, and the Borrower shall not have rights as a third party
beneficiary of any of such provisions.

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

63

 

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

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

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

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

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

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

     9.04 Reliance by Administrative Agent.

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

64

 

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

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

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

65

 

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

     9.08 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the Arrangers shall
have any powers, duties or responsibilities under this Agreement or any of the other Loan
Documents, except (i) in its capacity, as applicable, as the Administrative Agent or a Lender
hereunder or (ii) as expressly provided herein or therein.

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

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to
file such other documents as may be necessary or advisable in order to have the claims of
the Lenders and the Administrative Agent (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Lenders and the Administrative
Agent and their respective agents and counsel and all other amounts due the Lenders and the
Administrative Agent under Sections 2.06 and 10.04) allowed in such
judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender to make such payments to the
Administrative Agent and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its
agents and counsel, and any other amounts due the Administrative Agent under Sections 2.06
and 10.04.

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

66

 

9.10 Guaranty Matters. The Lenders irrevocably authorize the Administrative Agent, at its
option and in its discretion, to release any Guarantor from its obligations under the
Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted
hereunder.

     Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing
the Administrative Agent’s authority to release any Guarantor from its obligations under the
Guaranty pursuant to this Section 9.10. In each case as specified in this Section
9.10, the Administrative Agent will, at the Borrower’s expense, execute and deliver to the
applicable Loan Party such documents as such Loan Party may reasonably request to evidence the
release of such Guarantor from its obligations under the Guaranty, in each case in accordance with
the terms of the Loan Documents and this Section 9.10.

ARTICLE X.

     10.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Loan
Document, and no consent to any departure by the Borrower or any other Loan Party therefrom, shall

Loan Party, as the case may be, and acknowledged by the Administrative Agent, and each such waiver

them) hereunder or under any other Loan Document without the written consent of each Lender
directly affected thereby;

     (c) reduce the principal of, or the rate of interest specified herein on, any Loan or (subject to

that the foregoing shall not apply to notices to any Lender pursuant to Article II if such
Lender, as applicable, has notified the Administrative Agent that it is incapable of receiving
notices under such Article by electronic communication. The Administrative Agent or the Borrower
may, in its discretion, agree to accept notices and other communications to it hereunder by
electronic communications pursuant to procedures approved by it, provided that approval of
such procedures may be limited to particular notices or communications.

     Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to

FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE
BORROWER MATERIALS OR THE PLATFORM. In no event shall the Administrative Agent or any of its
Related Parties (collectively, the “Agent Parties”) have any liability to the Borrower, any
Lender, or any other Person for losses, claims, damages, liabilities or expenses of any kind
(whether in tort, contract or otherwise) arising out of the Borrower’s or the Administrative
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 such Agent Party; provided, however, that in no event shall
any Agent Party have any liability to the Borrower, any Lender or any other Person for indirect,
special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

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

     10.03 No Waiver; Cumulative Remedies.

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

relating to any of the foregoing, whether based on contract, tort or any other theory, whether
brought by a third party or by the Borrower or any other Loan Party, and regardless of whether any
Indemnitee is a party thereto, in all cases, whether or not caused by or arising, in whole or in
part, out of the comparative, contributory or sole negligence of the Indemnitee; provided that

70

 

such indemnity shall not, as to any Indemnitee,
be available to the extent that such losses, claims, damages, liabilities or related expenses (x)
are determined by a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a
claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in bad faith
of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or
such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as
determined by a court of competent jurisdiction.

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

     (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable
law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any
theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct
or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other
Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated
hereby or thereby, any Loan or the use of the proceeds thereof. No Indemnitee referred to in
subsection (b) above shall be liable for any damages arising from the use by unintended recipients
of any information or other materials distributed to such unintended recipients by such Indemnitee
through telecommunications, electronic or other information transmission systems in connection with
this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby other
than for direct or actual damages resulting from the gross negligence or willful misconduct of such
Indemnitee as determined by a final and nonappealable judgment of a court of competent
jurisdiction.

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

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

     10.05 Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to the
Administrative Agent or any Lender, or the Administrative Agent or any Lender exercises its right
of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently
invalidated, declared to be fraudulent or preferential, set aside or required

71

 

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

     10.06 Successors and Assigns.

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

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

          (i) Minimum Amounts.

          (A) in the case of an assignment of the entire remaining amount of the assigning
Lender’s Commitment or the Loans at the time owing to it or in the case of an
assignment to a Lender, an Affiliate of a Lender 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 Loans
outstanding thereunder) or, if the Commitment is not then in effect, the principal
outstanding balance of the Loans of the assigning Lender subject to each such
assignment, determined as of the date the Assignment and Assumption with

72

 

respect to
such assignment is delivered to the Administrative Agent or, if “Trade Date” is
specified in the Assignment and Assumption, as of the Trade Date, shall not be less
than $5,000,000 unless the Administrativ Agent 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 assignee (or to an 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 Lender’s rights and obligations under this
Agreement with respect to the Loans or the Commitment assigned;

          (iii) Required Consents. No consent shall be required for any assignment except
(x) to the extent required by subsection (b)(i)(B) of this Section and (y) subsequent to
the Syndication Completion Date, the consent of the Administrative Agent (such consent not
to be unreasonably withheld or delayed) shall be required if such assignment is to a Person
that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such
Lender.

          (iv) Assignment and Assumption. The parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee in the amount, if any, required as set forth in Schedule
10.06; provided, however, that the Administrative Agent may, in its
sole discretion, elect to waive such processing and recordation fee in the case of any
assignment. The assignee, if it is not a Lender, shall deliver to the Administrative 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.

          (vii) No Assignment During Syndication. Except pursuant to transactions arranged
by the Bridge Lead Arranger, no Lender may sell or assign (other than to an Affiliate) any
portion of its interest in the Initial Loans until the Syndication Completion Date

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c)
of this Section, from and after the effective date specified in each Assignment and Assumption, the
assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning

73

 

 Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04
with respect to facts and circumstances occurring prior to the effective date of such assignment.
Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee
Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that
does not comply with this subsection shall be treated for purposes of this Agreement as a
sale by such Lender of a participation in such rights and obligations in accordance with subsection
(d) of this Section.

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

     (d) Participations. Any Lender may at any time, without the consent of, or notice to, the
Borrower or the Administrative Agent (except as set forth below), sell participations to any Person
(other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries)
(each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations
under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it);
provided that (i) such Lender’s obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) the Borrower, the Administrative Agent and the Lenders shall continue to
deal solely and directly with such Lender in connection with such Lender’s rights and obligations
under this Agreement and (iv) prior to the Syndication Completion Date, no such participation may
be granted by any Lender except to an Affiliate of such Lender.

     Any agreement or instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, waiver or other modification described in the first proviso to
Section 10.01 that affects such Participant. Subject to subsection (e) of this Section,
the Borrower agrees that each Participant shall be entitled to the benefits of Sections
3.01, 3.04 and 3.05 to the same extent as if it were a Lender and had acquired
its interest by assignment pursuant to subsection (b) of this Section. To the extent permitted by
law, each Participant also shall be entitled to the benefits of Section 10.08 as though it
were a Lender, provided such Participant agrees to be subject to Section 2.03 as
though it were a Lender.

     (e) Limitations upon Participant Rights. A Participant shall not be entitled to receive
any greater payment under Section 3.01 or 3.04 than the applicable Lender would
have been entitled to receive with respect to the participation sold to such Participant, unless
the sale of the

74

 

participation to such Participant is made with the Borrower’s prior written
consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to
the benefits of Section 3.01 unless the Borrower is notified of the participation sold to
such Participant and such Participant agrees, for the benefit of the Borrower, to comply with
Section 3.01(e) as though it were a Lender.

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

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

     (h) Notice to Lead Arranger. The Lead Arranger shall be notified of any assignment or
participation (except to an Affiliate of the transferor Lender) until the 180th day
after the Closing Date.

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

75

 

     For purposes of this Section, “Information” means all information received from the
Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective
businesses, other than any such information that is available to the Administrative Agent or any
Lender on a nonconfidential basis prior to disclosure by the Borrower or any Subsidiary,
provided that, in the case of information received from the Borrower or any Subsidiary
after the date hereof, such information is clearly identified at
the time of delivery as nonpublic and 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 confidential information of a
similar nature.

     Each of the Administrative Agent and the Lenders 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 Law, including
Federal and state securities Laws.

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

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

76

 

     10.10 Counterparts; Integration; Effectiveness.
This Agreement may be executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement and the other Loan Documents constitute the
entire contract among the parties relating to the subject matter hereof and, except as otherwise
expressly provided in the Commitment Letter, supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except as provided in
Article IV, this Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received counterparts hereof
that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy shall be effective as
delivery of a manually executed counterpart of this Agreement.

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

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

     10.13 Replacement of Lenders. If (i) any Lender requests compensation under Section 3.04 or (ii)
the Borrower is required to pay any additional amount to any Lender or any Governmental Authority
for the account of any Lender pursuant to Section 3.01, or (iii) any Lender is unwilling to
approve an amendment hereto which has been approved by Super Majority Lenders but requires approval
of such Lender to be effective, then the Borrower may, at its sole expense and effort, upon notice
to such Lender and the Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in, and consents required
by, Section 10.06), all of its interests, rights and obligations under this Agreement and
the related Loan Documents to an assignee that shall assume such obligations (which assignee may be
another Lender, if a Lender accepts such assignment), provided that:

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

77

 

     (b) such Lender shall have received payment of an amount equal to the outstanding principal of its
Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and
under the other Loan Documents (including any amounts under Section 3.05) from the assignee
(to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the
case of all other amounts);

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

     (d) in the case of an assignment resulting from clause (iv) above, such assignment will result in
effectiveness of such increase or amendment; and

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

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

     10.14 Governing Law; Jurisdiction; Etc.

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

     (b) SUBMISSION TO JURISDICTION. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR
ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK
SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW

RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT
OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES
HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE
ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.
NOTHING IN THIS AGREEMENT OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE
ADMINISTRATIVE AGENT OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ITS PROPERTIES IN THE COURTS OF
ANY JURISDICTION.

     (c) WAIVER OF VENUE. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO

78

 

THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED
TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE
OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

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

     10.15
Waiver of Jury Trial. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     10.16 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction
contemplated hereby, the Borrower acknowledges and agrees that: (i) the credit facility provided
for hereunder and any related arranging or other services in connection therewith (including in
connection with any amendment, waiver or other modification hereof or of any other Loan Document)
are an arm’s-length commercial transaction between the Borrower and its Affiliates, on the one
hand, and the Administrative Agent and the Arrangers, on the other hand, and the Borrower is
capable of evaluating and understanding and understands and accepts the terms, risks and conditions
of the transactions contemplated hereby and by the other Loan Documents (including any amendment,
waiver or other modification hereof or thereof); (ii) in connection with the process leading to
such transaction, each of the Administrative Agent and the Arrangers is and has been acting solely
as a principal and is not the financial advisor, agent or fiduciary, for the Borrower or any of its
Affiliates, stockholders, creditors or employees or any other Person; (iii) neither the
Administrative Agent nor any Arranger has assumed or will assume an advisory, agency or fiduciary
responsibility in favor of the Borrower with respect to any of the transactions contemplated hereby
or the process leading thereto, including with respect to any amendment, waiver or other
modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent
or any Arranger has advised or is
currently advising the Borrower or any of its Affiliates on other matters) and neither the
Administrative Agent nor any Arranger has any obligation to the Borrower or any of its Affiliates
with respect to the

79

 

transactions contemplated hereby except those obligations expressly set forth
herein and in the other Loan Documents; (iv) the Administrative Agent and the Arrangers 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 Administrative Agent nor any
Arranger has any obligation to disclose any of such interests by virtue of any advisory, agency or
fiduciary relationship; and (v) the Administrative Agent and the Arrangers have not provided and
will not provide any legal, accounting, regulatory or tax advice with respect to any of the
transactions contemplated hereby (including any amendment, waiver or other modification hereof or
of any other Loan Document) and the Borrower has consulted its own legal, accounting, regulatory
and tax advisors to the extent it has deemed appropriate. The Borrower hereby waives and releases,
to the fullest extent permitted by law, any claims that it may have against the Administrative
Agent and any Arranger with respect to any breach or alleged breach of agency or fiduciary duty.

10.17
USA PATRIOT Act Notice. Each Lender that is subject to the Act (as hereinafter defined) and the
Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information
that identifies the Borrower, which information includes the name and address of the Borrower and

identify the Borrower in accordance with the Act.
