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

     2.02 Borrowings, Conversions and Continuations of Loans.

     (a) Each Borrowing, each conversion of 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 Loans, and (ii) on the requested date of any Borrowing of Base
Rate Loans. Each telephonic notice by the Borrower pursuant to this Section 2.02(a) must
be confirmed promptly by delivery to the Administrative Agent of a written 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

a conversion or continuation, then the applicable 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 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 Loan Notice, the Administrative Agent shall promptly notify each
Lender under the applicable Facility of the amount of its Applicable Percentage 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 a Term Borrowing or Revolving
Credit Borrowing, each Appropriate Lender shall make the amount of its Loan available to the
Administrative Agent in immediately available funds at 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 Loan Notice with respect to any
Revolving Credit 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
an Event of 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.

hereof.

     (v) No L/C Issuer shall be under any 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) Each 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 each 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 such 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 such L/C Issuer with respect to such acts or omissions, and
(B) as additionally provided herein with respect to the L/C Issuers.

     (b) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension 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 applicable 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 applicable 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 applicable 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 applicable 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, if any, to be presented by such beneficiary in case of any
drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary
in case of any drawing thereunder; and (G) such other matters as such L/C Issuer may
reasonably require. In the case of a request for an

-36-

 

amendment of any outstanding Letter of Credit, such Letter of Credit Application shall
specify in form and detail satisfactory to the applicable 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 such L/C
Issuer may reasonably require. Additionally, the Borrower shall furnish to the applicable
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
such L/C Issuer or the Administrative Agent may reasonably require.

     (ii) Promptly after receipt of any Letter of Credit Application, the applicable 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, such L/C Issuer will provide the Administrative Agent with a copy
thereof. Unless the applicable L/C Issuer has received written notice from any Revolving
Credit 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, such 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 such L/C Issuer’s usual and
customary business practices. Immediately upon the issuance of each Letter of Credit, each
Revolving Credit Lender shall be deemed to, and hereby irrevocably and unconditionally
agrees to, purchase from the applicable L/C Issuer a risk participation in such Letter of
Credit in an amount equal to the product of such Lender’s Applicable Revolving Credit
Percentage times the amount of such Letter of Credit.

     (iii) If the Borrower so requests in any applicable Letter of Credit Application, the
applicable 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
such 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 applicable L/C Issuer, the Borrower shall not be required
to make a specific request to such 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 applicable 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 such L/C Issuer shall not permit
any such extension if (A) such 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 five Business Days before the
Non-Extension Notice Date (1) from the Administrative Agent that the Required Lenders have
elected

-37-

 

not to permit such extension or (2) from the Administrative Agent, any Revolving Credit
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 such L/C Issuer
not to permit such extension.

     (iv) 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
applicable 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 applicable 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 applicable L/C Issuer under a Letter of Credit (each such date, an “Honor
Date”), the Borrower shall reimburse such L/C Issuer through the Administrative Agent in
an amount equal to the amount of such drawing. If the Borrower fails to so reimburse such
L/C Issuer by such time, the Administrative Agent shall promptly notify each Revolving
Credit Lender of the Honor Date, the amount of the unreimbursed drawing (the
“Unreimbursed Amount”), and the amount of such Lender’s Applicable Revolving Credit
Percentage thereof. In such event, the Borrower shall be deemed to have requested a
Revolving Credit 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 Revolving Credit Commitments and the conditions set forth
in Section 4.02 (other than the delivery of a Loan Notice and without giving effect
to the Borrower’s failure to so reimburse such L/C Issuer as provided in this Section
2.03(c) as a Default for purposes of Section 4.02). Any notice given by an 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 Revolving Credit Lender shall upon any notice pursuant to Section
2.03(c)(i) make funds available to the Administrative Agent for the account of the
applicable L/C Issuer at the Administrative Agent’s Office in an amount equal to its
Applicable Revolving Credit Percentage of the Unreimbursed Amount not later than 2:00 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 Loan to the Borrower in such amount. The
Administrative Agent shall remit the funds so received to the applicable L/C Issuer.

     (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a
Revolving Credit Borrowing of Base Rate Loans because the conditions set forth in
Section 4.02 (without giving effect to the Borrower’s failure to reimburse the
applicable

-38-

 

L/C Issuer as provided in this Section 2.03(c) as a Default for purposes of
Section 4.02) cannot be satisfied or for any other reason, the Borrower shall be
deemed to have incurred from the applicable 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 Revolving Credit Lender’s payment to the Administrative Agent for the account of
such 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 Revolving Credit Lender funds its Revolving Credit 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 Revolving Credit
Percentage of such amount shall be solely for the account of the applicable L/C Issuer.

     (v) Each Revolving Credit Lender’s obligation to make Revolving Credit Loans or L/C
Advances to reimburse the respective L/C Issuers 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 any 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 Revolving Credit Lender’s
obligation to make 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 Loan
Notice and without giving effect to the Borrower’s failure to reimburse the applicable L/C
Issuer as provided in this Section 2.03 as a Default for purposes of Section
4.02). No such making of an L/C Advance shall relieve or otherwise impair the
obligation of the Borrower to reimburse the applicable L/C Issuer for the amount of any
payment made by such L/C Issuer under any Letter of Credit issued by it, together with
interest as provided herein.

     (vi) If any Revolving Credit Lender fails to make available to the Administrative Agent
for the account of the applicable L/C Issuer any amount required to be paid by such Lender
pursuant to the foregoing provisions of this Section 2.03(c) by the time specified
in Section 2.03(c)(ii), such 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 such L/C Issuer at a rate per annum equal to the greater
of the Federal Funds Rate and a rate determined by such L/C Issuer in accordance with
banking industry rules on interbank compensation, plus any administrative, processing or
similar fees customarily charged by such 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 Loan included in the relevant Borrowing or L/C Advance in respect
of the relevant L/C Borrowing, as the case may be. A certificate of the applicable L/C
Issuer submitted to any Revolving Credit

-39-

 

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 applicable L/C Issuer has made a payment under any Letter of
Credit and has received from any Revolving Credit 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 such 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 Revolving Credit Lender its Applicable
Revolving Credit 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 an 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 applicable L/C Issuer in its discretion), each Revolving Credit Lender
shall pay to the Administrative Agent for the account of the applicable L/C Issuer its
Applicable Revolving Credit 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 Revolving Credit 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 respective
L/C Issuer for each drawing under each Letter of Credit issued by it 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), such L/C Issuer or any other Person, whether in connection with this
Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement
or instrument relating thereto, or any unrelated transaction;

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

-40-

 

     (iv) any payment by such 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 such 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 applicable L/C Issuer.
The Borrower shall be conclusively deemed to have waived any such claim against the applicable 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 applicable 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 any L/C
Issuer, the Administrative Agent, any of their respective Related Parties nor any correspondent,
participant or assignee of an 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 any L/C Issuer, the
Administrative Agent, any of their respective Related Parties nor any correspondent, participant or
assignee of an 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 or otherwise in any Loan Document to the contrary notwithstanding, the
Borrower may have a claim against the applicable L/C Issuer, and such L/C Issuer may be liable to
the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or
exemplary, damages suffered by the Borrower which the Borrower proves were caused by such L/C
Issuer’s willful misconduct or gross negligence or such L/C Issuer’s willful failure to pay under
any Letter of Credit issued by it after the presentation to it by the beneficiary of a sight draft,
certificate(s) or other documents strictly complying with the terms and conditions of a Letter of
Credit. In furtherance and not in limitation of the foregoing, an 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 applicable L/C

-41-

 

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. Within two Business Days following the request of the
Administrative Agent, (i) if an 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 2.06 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 Issuers and the Lenders, as
collateral for the L/C Obligations, cash or deposit account balances pursuant to documentation in
form and substance reasonably satisfactory to the Administrative Agent and the L/C Issuers (which
documents are hereby consented to by the Lenders). Derivatives of the term “Cash Collateralize”
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 deposit accounts, which may be interest-bearing at the Borrower’s election, at Bank of
America.

     (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the applicable
L/C Issuer and the Borrower when a Letter of Credit is issued by such L/C Issuer (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 Revolving Credit Lender in accordance with its Applicable Revolving Credit
Percentage a Letter of Credit fee (the “Letter of Credit Fee”) (i) for each commercial
Letter of Credit equal to the Applicable Margin times the daily amount available to be drawn under
such Letter of Credit, and (ii) for each standby Letter of Credit equal to the Applicable Margin
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 1.06. 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 Margin during
any quarter, the daily amount available to be drawn under each standby Letter of Credit shall be
computed and multiplied by the Applicable Margin separately for each period during such quarter
that such Applicable Margin was in effect. Notwithstanding anything to the contrary contained
herein, upon the request of the Required Revolving Credit Lenders, while any Event of Default
exists, all Letter of Credit Fees shall accrue at the Default Rate.

-42-

 

     (j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The
Borrower shall pay directly to the applicable L/C Issuer for its own account a fronting fee (i)
with respect to each Letter of Credit issued by such Issuing Lender, at a rate of 12.5 basis points
per annum, computed (a) with respect to each commercial Letter of Credit on the amount of such
Letter of Credit, and payable upon the issuance thereof, and (b) with respect to each standby
Letter of Credit, 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, 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) with respect to any amendment of a commercial Letter of Credit increasing the amount of
such Letter of Credit, at a rate separately agreed between the Borrower and the applicable L/C
Issuer, computed on the amount of such increase, and payable upon the effectiveness of such
amendment. 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
1.06. In addition, the Borrower shall pay directly to the applicable L/C Issuer for its own
account the customary issuance, presentation, amendment and other processing fees, and other
standard costs and charges, of such L/C Issuer relating to letters of credit as from time to time
in effect, effective schedules of which will be provided to the Borrower upon its request. Such
customary fees and standard costs and charges are due and payable within 30 days of demand therefor
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.

     (l) Letters of Credit Issued for Guarantors. Notwithstanding that a Letter of Credit
issued or outstanding hereunder is in support of any obligations of, or is for the account of, a
Guarantor, the Borrower shall be obligated to reimburse the applicable L/C Issuer hereunder for any
and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance
of Letters of Credit for the account of Guarantors inures to the benefit of the Borrower.

     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 Revolving Credit Percentage of the
Outstanding Amount of Revolving Credit Loans and L/C Obligations of the Lender acting as Swing Line
Lender, may exceed the amount of such Lender’s Revolving Credit Commitment; provided, however, that
after giving effect to any Swing Line Loan, (i) the Total Revolving Credit Outstandings shall not
exceed the Revolving Credit Facility at such time, and (ii) the aggregate Outstanding Amount of the
Revolving Credit Loans of any Revolving Credit Lender at such time, plus such Revolving
Credit Lender’s Applicable Revolving Credit Percentage of the Outstanding Amount of all L/C
Obligations at such time, plus such Revolving Credit Lender’s Applicable Revolving Credit
Percentage of the Outstanding Amount of all Swing Line Loans at such time shall not exceed such
Lender’s Revolving Credit Commitment, and provided, further,

-43-

 

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 2.05, 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 Revolving Credit Lender
shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swing
Line Lender a risk participation in such Swing Line Loan in an amount equal to the product of such
Lender’s Applicable Revolving Credit 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 4:00 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 Revolving Credit Lender make a Base Rate Revolving Credit
Loan in an amount equal to such Lender’s Applicable Revolving Credit 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 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 Revolving Credit Facility and the conditions set forth in Section
4.02. The Swing Line Lender shall furnish the Borrower with a copy of the applicable
Loan Notice promptly after delivering such notice to the Administrative Agent. Each
Revolving Credit Lender shall make an amount equal to its Applicable Revolving Credit
Percentage of the amount specified in such Loan Notice available to the Administrative Agent
in immediately available funds for the account of the Swing Line

-44-

 

Lender at the Administrative Agent’s Office not later than 2:00 p.m. on the day
specified in such 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 Revolving
Credit Loan to the Borrower in such amount. The Administrative Agent shall remit the funds
so received to the Swing Line Lender.

     (ii) If for any reason any Swing Line Loan cannot be refinanced by such a Revolving
Credit Borrowing in accordance with Section 2.04(c)(i), the request for Base Rate
Revolving Credit 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 Revolving Credit 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 Revolving Credit 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 Loan included in the relevant 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 Revolving Credit Lender (through the Administrative
Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent
manifest error.

     (iv) Each Revolving Credit Lender’s obligation to make Revolving Credit 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 Revolving Credit
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.

-45-

 

     (d) Repayment of Participations.

     (i) At any time after any Revolving Credit 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
Revolving Credit 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
settlement entered into by the Swing Line Lender in its discretion), each Revolving Credit
Lender shall pay to the Swing Line Lender its Applicable Revolving Credit 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 Revolving Credit 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 owing on the Swing Line Loans. Until each
Revolving Credit Lender funds its Base Rate Revolving Credit Loan or risk participation pursuant to
this Section 2.04 to refinance such Lender’s Applicable Revolving Credit Percentage of any
Swing Line Loan, interest in respect of such Applicable Revolving Credit 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 owing in respect of the Swing Line Loans directly to the Swing Line Lender.

     2.05 Optional Prepayments.

     (a) The Borrower may, upon notice to the Administrative Agent, at any time or from time to
time voluntarily prepay Loans under either Facility in whole or in part without premium or penalty;
provided that (i) such notice must be received by the Administrative Agent not later than 12:00
p.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 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 Loans shall be in a principal amount of $2,500,000 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 Loans under each Facility 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 applicable
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 by the Borrower, the Borrower shall make such
prepayment and the payment amount specified in such

-46-

 

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 respective Facilities in the manner indicated by the Borrower and to the Loans of
the Lenders under each applicable Facility in accordance with their respective Applicable
Percentages.

     (b) 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.

     2.06 Mandatory Prepayments.

     (a) If at any time the Total Revolving Credit Outstandings exceed the Revolving Credit
Facility, the Borrower shall immediately prepay Revolving Credit Loans, Swing Line Loans or Cash
Collateralize the L/C Obligations, or any combination of the foregoing, 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(a) unless after the
prepayment in full of the Revolving Credit Loans and the Swing Line Loans the Total Revolving
Credit Outstandings exceed the Revolving Credit Facility at such time.

     (b) If the Borrower or any of its Subsidiaries (other than, following the New Dive IPO, New
Dive) receives Net Cash Proceeds in excess of $2,500,000 from any Asset Disposition or any Recovery
Event (or series of related Asset Dispositions or Recovery Events), then (i) on the next Business
Day following the date of receipt by the Borrower or the applicable Subsidiary of such Net Cash
Proceeds and (ii) subject to Section 2.06(e), the Borrower shall prepay the Loans by an
amount equal to the amount of such Net Cash Proceeds, as set forth in Section 2.06(d);
provided, however that at the election of the Borrower, and so long as no Default shall
have occurred and be continuing, the Borrower, the applicable Subsidiary or any Loan Party (or any
combination of the foregoing) may reinvest all or any portion of such Net Cash Proceeds if such
reinvestment complies with the following requirements: (w) the Borrower shall deliver to the
Administrative Agent a certificate of a Responsible Officer to the effect that the Borrower and/or
any such permitted Subsidiary intends to reinvest all or any portion of such Net Cash Proceeds in
accordance with this Section 2.06(b), (x) the Borrower, the applicable Subsidiary or any
Loan Party (or any combination of the foregoing) shall reinvest such Net Cash Proceeds to acquire
Oil and Gas Properties or operating assets (including the construction of any such assets and the
Acquisition of all of the Equity Interests in one or more Persons owning or constructing any such
assets) or to improve, enlarge, develop, re-construct or repair the affected asset, or any
combination of the foregoing in each case, within 365 days after the receipt of the applicable Net
Cash Proceeds, (y) the Borrower, the applicable Subsidiary or any Loan Party (or any combination of
the foregoing) shall, in the case of any Disposition of, or Recovery Event with respect to, any
Collateral, reinvest such proceeds in assets of the type described in clause (x) above (including
the construction of such assets and the Acquisition of all of the Equity Interests

-47-

 

in one or more Persons owning or constructing such assets) which will constitute Collateral
and take all actions required by Section 6.13 with respect thereto (provided that
any Equity Interests purchased with Net Cash Proceeds of Collateral pursuant to this Section
2.06(b) shall be issued by a Person organized under the laws of any political subdivision of
the United States), and (z) the Borrower shall prepay the Loans, as set forth in Section
2.06(d), with any portion of such Net Cash Proceeds not expended in accordance with this
Section 2.06(b) within such period. Pending the application of any such Net Cash Proceeds,
the Borrower may reduce outstanding Indebtedness under the Revolving Credit Loans or invest such
Net Cash Proceeds in Cash Equivalents in which the Administrative Agent, for the benefit of the
Secured Parties, has a perfected first priority security interest, subject only to Permitted
Collateral Liens. The provisions of this Section do not constitute a consent to the consummation
of any Disposition not permitted by Section 7.05. With respect to any Asset Disposition or
Recovery Event which will result in Net Cash Proceeds in excess of $25,000,000, the Borrower shall
notify the Administrative Agent thereof on or prior to the date of the applicable Asset Disposition
or promptly following the date that the Borrower has actual knowledge that a Recovery Event has
occurred.

     (c) If any Indebtedness shall be issued or incurred by the Borrower or any of its Subsidiaries
(excluding any Indebtedness permitted to be incurred in accordance with Section 7.03(a)
through (f) and (h) through (n)), then on the next Business Day following
receipt by the Borrower or the applicable Subsidiary of the Net Cash Proceeds from such issuance or
incurrence, the Borrower shall prepay the Loans by an amount equal to the amount of such Net Cash
Proceeds, as set forth in Section 2.06(d). The provisions of this Section do not
constitute a consent to the issuance or incurrence of any Indebtedness by the Borrower or any of
its Subsidiaries not otherwise permitted hereunder.

     (d) Each prepayment of Loans pursuant to the foregoing provisions of Section 2.06
shall be applied, first, to the prepayment of the Term Loans on a pro rata basis and
second to the prepayment of the Revolving Credit Loans as provided in Section
2.06(f) below. Any prepayment of a Loan pursuant to this Section 2.06 shall be
accompanied by all accrued interest thereon, together with any additional amounts required pursuant
to Section 3.05. The amount of each prepayment of the Term Loans pursuant to this
Section 2.06 shall be applied ratably to the then remaining installments of the Term Loans.

     (e) Notwithstanding any of the other provisions of clause (b) or (c) of this Section
2.06, so long as no Default under Section 8.01(a) or Section 8.01(f), or Event
of Default shall have occurred and be continuing:

     (i) If, on any date on which a prepayment would otherwise be required to be made
pursuant to clause (b) or (c) of this Section 2.06, the aggregate amount of Net Cash
Proceeds required by such clause to be applied to prepay Loans on such date is less than or
equal to $5,000,000, the Borrower may defer such prepayment until the first date thereafter
on which the aggregate amount of Net Cash Proceeds or other amounts otherwise required under
clause (b) or (c) of this Section 2.06 to be applied to prepay Loans exceeds
$5,000,000. During such deferral period the Borrower may apply all or any part of such
aggregate amount to prepay Revolving Credit Loans and may, subject to the fulfillment of the
applicable conditions set forth in Article IV, reborrow such amounts

-48-

 

(which amounts, to the extent originally constituting Net Cash Proceeds, shall be
deemed to retain their original character as Net Cash Proceeds when so reborrowed) for
application as required by this Section 2.06. Upon the occurrence of a Default
under Section 8.01(a) or Section 8.01(f), or an Event of Default during any
such deferral period, the Borrower shall immediately prepay the Loans in the amount of all
Net Cash Proceeds received by the Borrower and other amounts, as applicable, that are
required to be applied to prepay Loans under this Section 2.06 (without giving
effect to the first and second sentences of this clause (e)) but which have not previously
been so applied.

     (ii) If, on any date on which a prepayment would otherwise be required to be made
pursuant to clause (b) or (c) of this Section 2.06, the Borrower may, upon prior
written notice to the Administrative Agent, elect to defer such all or any portion of such
required prepayment until the end of an Interest Period provided that (A) all of the
applicable Net Cash Proceeds not previously applied to prepay the Loans shall be deposited
in a blocked deposit account at Bank of America on or before the Business Day following
receipt of such proceeds and (B) such proceeds are applied to prepay the Loans at the end of
such Interest Period. The Borrower hereby grants to the Administrative Agent, for the
benefit of the Lenders, a security interest in all such cash, deposit accounts and all
balances therein and all proceeds of the foregoing. During the continuance of a Default
under Section 8.01(a) or Section 8.01(f), or an Event of Default during any
such deferral period, the Administrative Agent may, and at the direction of the Required
Banks shall, prepay the Loans in the amount of all Net Cash Proceeds and proceeds thereof on
deposit in, or credited to, such deposit account.

     (f) Prepayment of the Revolving Credit Facility made pursuant to this Section 2.06,
first, shall be applied ratably to the L/C Borrowings and the Swing Line Loans,
second, shall be applied ratably to the outstanding Revolving Credit Loans, and,
third, shall be used to Cash Collateralize the remaining L/C Obligations; and the amount
remaining, if any, after the prepayment in full of all L/C Borrowings, Swing Line Loans and
Revolving Credit Loans outstanding at such time and the Cash Collateralization of the remaining L/C
Obligations in full may be retained by the Borrower for use in the ordinary course of its business.
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 applicable L/C Issuer or the Revolving Credit Lenders, as
applicable.

     2.07 Termination or Reduction of Commitments.

     (a) Optional. The Borrower may, upon notice to the Administrative Agent, terminate
the Revolving Credit Facility, the Letter of Credit Sublimit or the Swing Line Sublimit, or any
combination of them, as the case may be, or at any time or from time to time permanently reduce the
Revolving Credit Facility, the Letter of Credit Sublimit or the Swing Line Sublimit, or any
combination of them, as the case may be; provided that (i) any such notice shall be
received by the Administrative Agent not later than 11:00 a.m. three 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 Revolving Credit Facility if, after giving effect thereto and to any

-49-

 

concurrent prepayments hereunder, the Total Revolving Credit Outstandings would exceed the
Revolving Credit Facility, and (iv) if, after giving effect to any reduction of the Revolving
Credit Facility, the Letter of Credit Sublimit or the Swing Line Sublimit exceeds the amount of the
Revolving Credit Facility, such Sublimit shall be automatically reduced by the amount of such
excess. The Administrative Agent will promptly notify the Revolving Credit Lenders of any such
notice of termination or reduction of the Revolving Credit Facility. Any reduction of the
Revolving Credit Facility shall be applied to the Revolving Credit Commitment of each Revolving
Credit Lender according to its Applicable Revolving Credit Percentage. All fees accrued until the
effective date of any termination of the Revolving Credit Facility shall be paid on the effective
date of such termination.

     (b) Mandatory. The aggregate Term Commitments shall be automatically and permanently
reduced to zero on the date of, and after giving effect to, the Term Borrowing.

     2.08 Repayment of Loans.

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

     (b) The Borrower shall repay each Swing Line Loan on the earlier to occur of (i) the date five
Business Days after such Loan is made and (ii) the Revolving Credit Maturity Date.

     (c) The Borrower shall repay to the Term Lenders the aggregate outstanding principal amount of
all Term Loans as follows: (i) on the last Business Day of each March, June, September and
December, commencing with September 30, 2006, the Borrower shall repay Term Loans in the aggregate
principal amount of $2,100,000 (which amounts shall be reduced as a result of the application of
prepayments in accordance with the order of priority set forth in Section 2.06) and (ii) on
the Term Loan Maturity Date, the Borrower shall repay the aggregate principal amount of all Term
Loans outstanding on such date.

     2.09 Interest.

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

     (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
from time to time outstanding shall thereafter bear interest at a fluctuating interest

-50-

 

rate per annum at all times thereafter until paid 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, or, with respect to any amounts payable solely in respect of Revolving Credit
Commitments or Letters of Credit, the Required Revolving Credit 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 Revolving Credit Lender in accordance with its Applicable Revolving Credit
Percentage, a commitment fee equal to the Applicable Margin times the actual daily amount by which
the Revolving Credit Facility exceeds the sum of (i) the Outstanding Amount of Revolving Credit
Loans and (ii) the Outstanding Amount of L/C Obligations. 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 Margin during any quarter, the actual daily amount shall be computed and multiplied by
the Applicable Margin separately for each period during such quarter that such Applicable Margin
was in effect.

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

-51-

 

     (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.

     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

-52-

 

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
3:00 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 3:00 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
Borrowing of Eurodollar Rate Loans (or, in the case of any Borrowing of Base Rate Loans, prior to
1:00 p.m. on the date of such Borrowing) that such Lender will not make available to the
Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume
that such Lender has made such share available on such date in accordance with Section 2.02
(or, in the case of a 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 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 Borrowing to the Administrative Agent, then the amount so
paid shall constitute such Lender’s Loan included in such 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 an L/C
Issuer hereunder that the Borrower will not make such payment, the Administrative Agent may
assume that the Borrower has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Appropriate Lenders or the applicable
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 Appropriate Lenders or the applicable L/C Issuer,
as the case may be, severally agrees to

-53-

 

repay to the Administrative Agent forthwith on demand the amount so distributed to such
Lender or such 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
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 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 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 (a) Obligations in respect of any of the
Facilities due and payable to such Lender hereunder and under the other Loan Documents at such time
in excess of its ratable share (according to the proportion of (i) the amount of such Obligations
due and payable to such Lender at such time to (ii) the aggregate amount of the Obligations in
respect of the Facilities due and payable to all Lenders hereunder and under the other Loan
Documents at such time) of payments on account of the Obligations in respect of the Facilities due
and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by
all the Lenders at such time or (b) Obligations in respect of any of the Facilities owing (but not
due and payable) to such Lender hereunder and under the other Loan Documents at such time in excess
of its ratable share (according to the proportion of (i) the amount of such Obligations owing (but
not due and payable) to such Lender at such time to (ii) the aggregate amount of the Obligations in
respect of the Facilities owing (but not due and payable) to all Lenders hereunder and under the
other Loan Parties at such time) of payment on account of the Obligations in respect of the
Facilities owing (but not due and payable) to all Lenders hereunder and under the other Loan
Documents at such time obtained by all of the

-54-

 

Lenders at such time 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 and subparticipations in L/C Obligations and 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 the aggregate amount of Obligations in respect of
the Facilities then due and payable to the Lenders or owing (but not due and payable) to the
Lenders, as the case may be, provided that:

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

     (ii) the provisions of this Section shall not be construed to apply to (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 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.

-55-

 

     (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 each 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 such L/C Issuer, 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 or an 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 an 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,

-56-

 

     (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, any Lender or any 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 such 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 such 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 such 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 any 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 Change in 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.

-57-

 

     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 (i) in respect to the applicable amount and Interest Period referred to in
the preceding clause (a), or (ii) in the circumstances referred to in the preceding clauses (b) and
(c), 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)) or any L/C Issuer;

     (ii) subject any Lender or any 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 such 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 such L/C Issuer); or

     (iii) impose on any Lender or any 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 such 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 such L/C
Issuer hereunder (whether of principal, interest or any other amount) then, upon request of such
Lender or such L/C Issuer, the Borrower will pay to such Lender or such L/C Issuer, as the case may
be, such additional amount or amounts as will compensate such Lender or such L/C Issuer, as the
case may be, for such additional costs incurred or reduction suffered.

-58-

 

     (b) Capital Requirements. If any Lender or any L/C Issuer determines that any Change
in Law affecting such Lender or such L/C Issuer or any Lending Office of such Lender or such
Lender’s or such 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 such L/C Issuer’s capital or on
the capital of such Lender’s or such 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 such L/C Issuer, to a level below
that which such Lender or such L/C Issuer or such Lender’s or such L/C Issuer’s holding company
could have achieved but for such Change in Law (taking into consideration such Lender’s or such L/C
Issuer’s policies and the policies of such Lender’s or such L/C Issuer’s holding company with
respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such
L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or
such L/C Issuer or such Lender’s or such L/C Issuer’s holding company for any such reduction
suffered.

     (c) Certificates for Reimbursement. A certificate of a Lender or an L/C Issuer
setting forth the amount or amounts necessary to compensate such Lender or such 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 such L/C Issuer, as the case may be, the amount shown as due on any such certificate
within 10 days after receipt thereof. Upon request by the Borrower, a Lender or L/C Issuer shall
also provide a certificate that such Lender or L/C Issuer is generally requesting such compensation
from other borrowers which such Lender or L/C Issuer deems similarly-situated to the Borrower.

     (d) Delay in Requests. Failure or delay on the part of any Lender or any L/C Issuer
to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a
waiver of such Lender’s or such L/C Issuer’s right to demand such compensation, provided that the
Borrower shall not be required to compensate a Lender or an L/C Issuer pursuant to the foregoing
provisions of this Section for any increased costs incurred or reductions suffered more than nine
months prior to the date that such Lender or such 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 such 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

-59-

 

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

For purposes of calculating amounts payable by the Borrower to the Lenders under this Section
3.05, 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 gives a notice pursuant to Section 3.02 (which notice is not given by other
similarly situated Lenders) and does not subsequently designate a different Lending Office or
assign its rights and obligations hereunder to another of its offices, branches or affiliates as

-60-

 

provided above, 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.

Adverse Effect.

     5.02 Authorization; No Contravention. The execution, delivery and performance by each Loan
Party of each Loan Document to which such Person is party, have been duly authorized by all
necessary corporate or equivalent action, and do not and will not (a) violate the terms of any of
such Person’s Organizational Documents; (b) conflict with or result in any breach of or default

restraining, preventing or imposing materially adverse conditions upon such portion of the
Transaction or the rights of the

-67-

 

Loan Parties or their Subsidiaries to transfer or otherwise dispose of, or to create any Lien
on, any properties now owned or hereafter acquired by any of them.

hereunder, will have been, duly executed and delivered by each Loan Party that is party thereto.

case may be, enforceable against such Loan Party in accordance with its terms, except as such
enforcement may be limited by Debtor Relief Laws and similar Laws affecting creditors’ rights
generally or providing relief for debtors and subject to general principles of equity.

     5.05 Financial Statements; No Material Adverse Effect; No Internal Control Event.

to the best knowledge of the Borrower, Remington and its Subsidiaries, as applicable, dated March
31, 2006, and the related consolidated statements of income or operations, shareholders’ equity and
cash flows for the fiscal quarter ended on that date (i) were prepared in accordance with GAAP
consistently applied throughout the period covered thereby, except as otherwise expressly noted
therein, and (ii) fairly present the consolidated financial condition of the Borrower and its
Subsidiaries and Remington and its Subsidiaries, as applicable, as of the date thereof and their
consolidated results of operations for the period covered thereby, subject, in the case of clauses
(i) and (ii), to the absence of footnotes and to normal year-end audit adjustments.

     (c) The estimates of the proved reserves attributable to the Oil and Gas Properties in the
Reserve Reports dated as of December 31, 2005, were prepared in accordance with standard geological
and engineering methods generally accepted in the oil and gas industry. The estimates of the lease
operating expenses in such Reserve Reports are reasonable and represent the historical lease
operating expenses associated with the Oil and Gas Properties, in each case in all material
respects. The historical factual information supplied by the Borrower and its Subsidiaries
(including Remington and its Subsidiaries) to the engineers in connection with the preparation of
such Reserve Reports was accurate and complete in all material respects. With respect to each of
the foregoing representations in this clause (c) regarding estimates or information of Remington or
its Subsidiaries, such representation is made (solely to the extent

-68-

 

such representations relate to Remington and its Subsidiaries) to the best knowledge of the
Borrower after due inquiry.

     (d) Since the date of the most recent financial statements furnished pursuant to Section
6.01(a) (or, until the date of the initial delivery of financial statements pursuant to such
Section, since the date of the Helix Audited Financial Statements), there has been no event or
circumstance, either individually or in the aggregate, that has had or could reasonably be expected
to have a Material Adverse Effect.

     (e) To the best knowledge of the Borrower, no Internal Control Event exists or has occurred
since the date of the Helix Audited Financial Statements that has resulted in or could reasonably
be expected to result in a misstatement in any material respect, in any material financial
information delivered or to be delivered to the Administrative Agent or the Lenders, of (i)
covenant compliance calculations provided hereunder or (ii) the assets, liabilities, financial
condition or results of operations of the Borrower and its Subsidiaries on a consolidated basis.

     (f) The consolidated forecasted balance sheet and statements of income and cash flows of the
Borrower and its Subsidiaries delivered pursuant to Section 4.01 or Section 6.01(c)
were prepared in good faith on the basis of the assumptions stated therein, which assumptions were
reasonable in light of the conditions existing when made and, and represented, at the time of
delivery, the Borrower’s good faith best estimate of its future financial condition and
performance.

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

     5.07 No Default. Neither any Loan Party nor any Subsidiary thereof is in default under, or in
breach of, any Contractual Obligation to which it is a party or by which it is bound that could,
either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.
No Default has occurred and is continuing or would result from the consummation of the transactions
contemplated by this Agreement or any other Loan Document.

     5.08 Ownership of Property; Liens. Each of the Borrower and each Subsidiary has good and
defensible title to, or valid leasehold interests in, all real property necessary or used in the
ordinary conduct of its business, except for such defects in title as could not, individually or in
the aggregate, reasonably be expected to materially detract from the value thereof to, or the use
thereof in, the business of the Borrower and its Subsidiaries. The property of the Borrower and
its Subsidiaries is subject to no Liens, other than Liens permitted by Section 7.01.

     5.09 Environmental Compliance.

     (a) The Borrower and its Subsidiaries are in compliance with all applicable Environmental
Laws, and have no liability under any Environmental Laws, except for such non-

-69-

 

compliance or liability which would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

     (b) The Borrower and its Subsidiaries hold all Environmental Permits (each of which is in full
force and effect) necessary for the operation of its business and for the use of any property
owned, leased, or otherwise operated by them, except for such Environmental Permits the failure to
hold which would not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

     (c) There (i) are no pending or, to the knowledge of the Borrower, threatened, claims against
the Borrower or any Subsidiary under any Environmental Laws, and, (ii) neither the Borrower nor any
Subsidiary has received any written notice of alleged non-compliance with applicable Environmental
Laws or Environmental Permits which, in each case, would, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

     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 deductibles and covering such risks as are customarily carried by companies
engaged in similar businesses and owning similar properties in localities where the Borrower or the
applicable Subsidiary operates, except to the extent that reasonable self insurance meeting the
same standards is maintained with respect to such risks.

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

     5.12 ERISA Compliance.

     (a) Except where the failure to comply therewith, either individually or in the aggregate,
could not reasonably be expected to have a Material Adverse Effect, each Plan is in compliance with
applicable Laws. Except as could not reasonably be expected to have a Material Adverse Effect, the
Borrower and each ERISA Affiliate have made all required contributions to each Plan subject to
Section 4.12 of the Code and no application for a funding waiver or an extension of any
amortization period pursuant to Section 412 of the Code has been made with respect to any Pension
Plan.

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

-70-

 

     (c) (i) No ERISA Event has occurred that would reasonably be expected to result in an Event of
Default and (ii) in each case except as could not reasonably be expected to have a Material Adverse
Effect, either individually or in the aggregate, (A) neither the Borrower nor any ERISA Affiliate
has incurred any liability under Title IV of ERISA with respect to any Pension Plan (other than
premiums due and not delinquent under Section 4007 of ERISA), (B) neither the Borrower nor any
ERISA Affiliate has incurred any liability (and no event has occurred which, with the giving of
notice under Section 4219 of ERISA, would result in such liability) under Section 4201 or 4243 of
ERISA with respect to a Multiemployer Plan, and (C) neither the Borrower nor any ERISA Affiliate
has engaged in a transaction that is subject to Section 4069 or 4212(c) of ERISA.

     (d) The aggregate actuarial present value of accumulated plan benefit liabilities of each
Pension Plan (determined utilizing the assumptions specified for funding purposes in the most
recent actuarial valuation for each such Pension Plan) did not, as of the end of the most recent
plan year, exceed the aggregate fair market value of the assets of such Pension Plan by an amount
that is material to the Borrower and its Subsidiaries, taken as a whole. The aggregate actuarial
present value of all accumulated post-retirement benefit obligations of each Borrower and its ERISA
Affiliates (determined utilizing the assumptions used for purposes of Statement of Financial
Accounting Standards No. 106) under Plans which are welfare benefit plans (as defined in Section
3(1) of ERISA), as of the most recent valuation dates reflected in the Borrower’s annual financial
statements contained in the Borrower’s most recent Form 10-K, are reflected on such financial
statements in accordance with the Statement of Financial Accounting Standards No. 106.

5.13 free and clear of all Liens (other than those created under the Security Documents and any
applicable Permitted Liens). As of the Closing Date, the Borrower has no equity investments in any
other corporation or entity other than those specifically disclosed in Part(b) of Schedule

fully paid and nonassessable.

     5.14 Margin Regulations; Investment Company Act; Public Utility Holding 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. Following the application of the proceeds of each Borrowing or drawing under each
Letter of Credit, not more than 25% of the value of the assets (either of the Borrower only or of
the Borrower and its Subsidiaries on a consolidated basis) subject to the provisions of Section
7.01 or Section 7.05 or subject to any restriction contained in any agreement or
instrument between the Borrower and any Lender or any Affiliate of any Lender relating to
Indebtedness and within the scope of Section 8.01(e) will be margin stock.

-71-

 

     (b) None of the Borrower, any Person Controlling the Borrower, or any Subsidiary (i) is a
“holding company,” or a “subsidiary company” of a “holding company,” or an “affiliate” of a
“holding company” or of a “subsidiary company” of a “holding company,” within the meaning of the

     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 a party or by which it is bound, and all other matters known to it, that, individually or in the
aggregate, could, if breached or violated by, enforced against, or adversely determined in relation
to, the Borrower or any of its Subsidiaries, reasonably be expected to result in a Material Adverse
Effect. No report, financial statement, certificate or other information furnished (whether in
writing or orally) 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 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.

     5.16 Compliance with Laws. Each of the Borrower and each Subsidiary thereof is in compliance
in all material respects with the requirements of all Laws and all orders, writs, injunctions and
decrees binding on 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 Taxpayer Identification Number. As of the Closing Date, the Borrower’s true and correct
U.S. taxpayer identification number is set forth on Schedule 10.02, and after the Closing
Date, as disclosed by the Borrower in writing to the Administrative Agent.

rights, franchises, licenses and other intellectual property rights (collectively, “IP
Rights”) that are reasonably necessary for the operation of their respective businesses,
without conflict with the rights of any other Person unless such failure to own or possess the
right to use such IP Rights would not reasonably be expected to have a Material Adverse Effect. To
the best knowledge of the Borrower, no slogan or other advertising device, product, process,
method, substance, part or other material now employed, or now contemplated to be employed, by the
Borrower or any Subsidiary infringes upon any rights held by any other Person in a manner that
would reasonably be expected to have a Material Adverse Effect. No claim or litigation regarding
any of the foregoing is pending or, to the best knowledge of the Borrower, threatened,

-72-

 

against the Borrower or Subsidiaries, or their use thereof, which, either
individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

     5.19 Intentionally Left Blank.

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

     5.21 Off-Balance Sheet Liabilities. Neither the Borrower nor any of its Subsidiaries have any

could reasonably be expected to have a Material Adverse Effect.

Materials as not containing any material non-public information (although it may be sensitive or
proprietary) 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 so 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

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 Issuers hereby irrevocably appoints Bank of America to act
on its behalf as the Administrative Agent hereunder and under the other Loan Documents and
authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers
as are delegated to the Administrative Agent by the terms hereof or thereof, together with such
actions and powers as are reasonably incidental thereto. The provisions of this Article are solely
for the benefit of the Administrative Agent, the Lenders and the L/C Issuers, 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, Swing Line Lender (if
applicable), potential Hedge Bank and potential Cash Management Bank) and the L/C Issuers hereby
irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and
such 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 Security Documents, or for exercising
any rights and remedies thereunder at the 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.

-101-

 

     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 applicable 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 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

-102-

 

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 an L/C Issuer, the Administrative Agent may presume
that such condition is satisfactory to such Lender or such L/C Issuer unless the Administrative
Agent shall have received notice to the contrary from such Lender or such 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 Issuers 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 Issuers, appoint a successor
Administrative Agent meeting the qualifications set forth above; provided that if the
Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has
accepted such appointment, then such resignation shall nonetheless become effective in accordance
with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder and under the other Loan Documents (except that in the case of any collateral
security held by the Administrative Agent on behalf of the Lenders or the L/C Issuers 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 applicable 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

-103-

 

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 each 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 each 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, none of the Book
Managers, Arrangers or Syndication or Documentation Agents, if any, listed on the cover page hereof
shall have any powers, duties or responsibilities under this Agreement or any of the other Loan
Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or an L/C
Issuer hereunder.

     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

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,
any 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, any L/C Issuer or any other Person for indirect,
special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

Issuer and the Swing Line Lender may change its address, telecopier or telephone number for notices

(including telephonic 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, each 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 made
pursuant to this Agreement 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, any 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

(INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE)

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

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

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), any 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), such 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 such L/C Issuer 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) or such L/C Issuer in connection with such capacity. The obligations of the

-111-

 

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

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

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, any L/C Issuer or any Lender, or the Administrative Agent, any
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, such 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 each 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 Issuers under clause (b) of the
preceding sentence shall survive the payment in full of the Obligations and the termination of this
Agreement.

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 Issuers 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 Eligible
Assignees all or a portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans (including 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 under any Facility and the Loans at the time owing to
it under such Facility or in the case of an assignment in respect of the Term
Commitment 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 outstanding
principal 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, in the case of any assignment in respect of the Revolving Credit
Facility, and $1,000,000, in the case of any assignment in respect of the Term
Commitment, in each case, 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 Eligible Assignee and members of its Assignee Group) will be treated as a single
assignment for purposes of determining whether such minimum amount has been met;

     (ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning 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:

-113-

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 (y) in the case
of an assignment in respect of any Revolving Credit Commitment, to a Revolving
Credit Lender or (z) in the case of any assignment in respect of any Term Loan, 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 for assignments in respect of
(i) any Term Commitment or Revolving Credit Commitment if such assignment is to a
Person that is not a Lender with a Commitment in respect of the applicable Facility
or, in the case of any assignment in respect of any Term Commitment, an Affiliate of
such Lender or an Approved Fund with respect to such Lender or (ii) any Term Loan to
a Person that is not a Lender, an Affiliate of a Lender or an Approved Fund;

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

     (D) the consent of the Swing Line Lender (such consent not to be unreasonably
withheld or delayed) shall be required by any assignment of any Revolving Credit
Commitment.

     (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. For the avoidance of doubt, no part of any such processing and recordation fee
shall be payable by or otherwise for the account of any Loan Party, directly or indirectly.
The Eligible 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
Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its

-114-

 

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 Lender. The assignor shall, if its entire Commitment
was assigned, return the cancelled original Note of such assignor to the Borrower following a
request therefor. 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, a competitor of the Borrower (as defined below), 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 Issuers
shall continue to deal solely and directly with such Lender in connection with such Lender’s rights
and obligations under this Agreement. As used above, a “competitor” of the Borrower shall mean any
Person principally engaged in the business of exploration for and production of oil and/or gas,
providing contracting services to others with respect to oil and/or gas exploration and production,
or a combination of the foregoing. The Borrower shall, upon request of any Lender, advise such
Lender as to whether the Borrower considers a proposed Participant to be a competitor. Any such
determination shall be made by the Borrower promptly and in good faith.

     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

-115-

 

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, which consent shall constitute the express waiver by the Borrower of the foregoing
limitation. 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, and all costs, fees and expenses related to any such pledge, including the release thereof,
shall be for the sole account of such Lender (without, for the avoidance of doubt, direct or
indirect reimbursement from any Loan Party).

     (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 of such Granting Lender 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 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 Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or
any part of such Loan, the Granting Lender shall be obligated to make such 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

-116-

 

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 Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the
same extent, and as if, such 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 in this Section 10.06, 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 Loan to its Granting Lender and (ii) disclose on a confidential
basis as provided herein any non-public information relating to its funding of 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) of this Section, Bank of America may, (i) upon 30
days’ notice to the Borrower and the Lenders, resign as an 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 an
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 an 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 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 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, issued by Bank of America 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.

Additionally, if at any time any other Lender serving as an L/C Issuer hereunder assigns all of its
Commitment and Revolving Credit Loans pursuant to subsection (b) of this Section, such Lender
shall, upon 30 days’ notice to the Administrative Agent and the Borrower, resign as L/C Issuer. In
the event of any such resignation as L/C Issuer, the Borrower shall be entitled to appoint from

-117-

 

among the Lenders a successor L/C Issuer; provided, however, that no failure by the Borrower to
appoint any such successor shall affect the resignation of such Lender as L/C Issuer. If such
Lender resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of an
L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the effective date of
its resignation as an L/C Issuer and all L/C Obligations with respect thereto (including the right
to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts
pursuant to Section 2.03(c)). Upon the appointment of a successor L/C Issuer, (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 (b) the successor L/C Issuer shall issue letters of credit in
substitution for the Letters of Credit, if any, issued by such retiring L/C Issuer and outstanding
at the time of such succession or make other arrangements satisfactory to such retiring L/C Issuer
to effectively assume the obligations of such retiring L/C Issuer 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 Issuers 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 (and in each such case, such Person shall, if permitted by law,
notify the Borrower of such occurrence as soon as reasonably practicable following the service of
any such process on such Person), (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, (ii) any pledgee referred to
in Section 10.06(f), or (iii) any actual or prospective counterparty (or its advisors) to
any swap or derivative transaction relating to the Borrower and its obligations, (g) with the
consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other
than as a result of a breach of this Section or (y) becomes available to the Administrative Agent,
any Lender, any 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 Affiliate of any of
them, or any of their respective businesses, other than any such information that is available to
the Administrative Agent, any Lender or any 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 confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered to have complied
with its obligation

-118-

 

to do so if such Person has exercised the same degree of care to maintain the confidentiality
of such Information as such Person would accord to its own confidential information.

     Each of the Administrative Agent, the Lenders and the L/C Issuers 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, each 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,
such 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 such L/C Issuer, irrespective of whether or not such
Lender or such 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 such L/C Issuer different from the branch or office holding
such deposit or obligated on such indebtedness. The rights of each Lender, each 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, such 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 (including amounts not so denominated but deemed to be “interest” under
applicable law) charged, paid, collected, taken, reserved, or agreed to be paid under any Loan
Document shall not exceed the maximum amount or maximum rate of non-usurious interest permitted to
be contracted for, charged, collected, reserved, taken or received by applicable Law (the
“Maximum Amount and the “Maximum Rate”, as the case may be). If the Administrative
Agent, any L/C Issuer or any Lender shall contract for, charge, collect, reserve, take or receive
such interest in an amount that exceeds the Maximum Amount or calculated at 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, and in no event shall any Person ever be liable for the
payment of unearned interest on, or in respect or as a part of, the Obligations. In determining
whether the interest contracted for, charged, collected, reserved, taken or received exceeds the
Maximum Amount or an amount calculated at 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.

-119-

 

     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 supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except as provided in
Section 4.01, this Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received counterparts hereof
that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an
executed counterpart of a signature page of this Agreement by telecopy or electronic transmission
shall be effective as delivery of an original 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 any Lender requests compensation under Section 3.04
or gives a notice pursuant to Section 3.02 (which notice is not given by other similarly
situated Lenders) and does not subsequently designate a different Lending Office or assign its
rights and obligations hereunder to another of its offices, branches or affiliates as provided in
Section 3.06(a), 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, if
any Lender is a Defaulting Lender, or if any other circumstance exists hereunder that gives the
Borrower the right to replace a Lender as a party hereto 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:

-120-

 

     (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, a notice pursuant to Section 3.02 (which notice is not given by other
similarly situated Lenders) not followed by the designation of a different Lending Office or
assignment to another office, branch or affiliate as provided in Section 3.06(a), or
payments required to be made pursuant to Section 3.01, such assignment will result in a
reduction in such compensation or payments thereafter; and

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

     A 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. EACH PARTY HERETO IRREVOCABLY AND UNCONDITIONALLY

ACTION OR PROCEEDING RELATING TO THIS AGREEMENT

-121-

 

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

     (c) WAIVER OF VENUE. EACH PARTY HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES
HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT 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
facilities provided for hereunder and any related arranging or other services in connection
therewith provided as of the date hereof 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 has acted 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 the Arranger has assumed or will assume an advisory, agency or
fiduciary responsibility in favor of the Borrower with respect to any of the

-122-

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 Collateral and Guaranty Matters.

     (a) Liens granted to or held by the Administrative Agent under any Loan Document shall be

     10.18 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

     10.19 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE
PARTIES.
