     SECTION 2.02 Loans.

          (a) Each Loan (other than Swingline Loans) shall be made as part of a Borrowing consisting
of Loans made by the Lenders ratably in accordance with their applicable Commitments; provided
that the failure of any Lender to make its Loan shall not in itself relieve any other Lender of
its obligation to lend hereunder (it being understood, however, that no Lender shall be

- 36 -

 

Section
2.03. Each Lender may at its option make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such
option shall not affect the obligation of Borrower to repay such Loan in accordance with the
terms of this Agreement. Borrowings of more than one Type may be outstanding at the same time;
provided that Borrower shall not be entitled to request any Borrowing that, if made, would
result in more than twelve Eurodollar Borrowings outstanding hereunder at any one
time. For purposes of the foregoing, Borrowings having different Interest Periods,
regardless of whether they commence on the same date, shall be considered separate Borrowings.

          (c) Except with respect to Loans deemed made pursuant to Section 2.18(e)(ii), each
Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds to such account in New York City as the Administrative
Agent may designate not later than 11:00 a.m., New York City time, and the Administrative Agent
shall promptly credit the amounts so received to an account as directed by Borrower in the
applicable Borrowing Request maintained with the Administrative Agent or, if a Borrowing shall
not occur on such date because any condition precedent herein specified shall not have been met,
return the amounts so received to the respective Lenders.

          (d) Unless the Administrative Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the Administrative Agent such
Lender’s portion of such Borrowing, the Administrative Agent may assume that such Lender has
made such portion available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above, and the Administrative Agent may, in reliance upon such
assumption, make available to Borrower on such date a corresponding amount. If the
Administrative Agent shall have so made funds available, then, to the extent that such Lender
shall not have made such portion available to the Administrative Agent, each of such Lender and
Borrower severally agrees to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date such amount is
made available to Borrower until the date such amount is repaid to the Administrative Agent at
(i) in the case of Borrower, the interest rate applicable at the time to the Loans comprising
such Borrowing and (ii) in the case of such Lender, the greater of the Federal Funds Effective
Rate and a rate determined by the Administrative Agent in accordance with banking industry rules
on interbank compensation. If such Lender shall repay to the Administrative Agent such
corresponding amount, such amount shall constitute such Lender’s Loan as part of such Borrowing
for purposes of this Agreement, and Borrower’s obligation to repay the Administrative Agent such
corresponding amount pursuant to this Section 2.02(d) shall cease.

          (e) Notwithstanding any other provision of this Agreement, Borrower shall not be entitled
to request, or to elect to convert or continue, any Borrowing if the Interest Period requested
with respect thereto would end after the Revolving Maturity Date or Term Loan Maturity Date, as
applicable.

          (a) Promise to Repay. Borrower hereby unconditionally promises to pay (i) to the
Administrative Agent for the account of each Term Loan Lender, the principal amount of each Term
Loan of such Term Loan Lender on the Term Loan Maturity Date, (ii) to the Administrative Agent
for the account of each Revolving Lender, the then unpaid principal amount of each Revolving
Loan of such Revolving Lender on the Revolving Maturity Date and (iii) to the Swingline Lender,
the then unpaid principal amount of each Swingline Loan on the earlier of the Revolving Maturity
Date and the first date after such Swingline Loan is made that is the 15th or last
day of a calendar month and is at least two Business Days after such Swingline Loan is made;
provided that on each date that a Revolving Borrowing is

- 38 -

 

made, Borrower shall repay all
Swingline Loans that were outstanding on the date such Borrowing is made.

          (b) Lender and Administrative Agent Records. Each Lender shall maintain in
accordance with its usual practice an account or accounts evidencing the indebtedness of
Borrower to such Lender resulting from each Loan made by such Lender from time to time,
including the amounts of principal and interest payable and paid to such Lender from time
to time under this Agreement. The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type and Class thereof and the Interest
Period applicable thereto; (ii) the amount of any principal or interest due and payable or to
become due and payable from Borrower to each Lender hereunder; and (iii) the amount of any sum
received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s
share thereof. The entries made in the accounts maintained pursuant to this paragraph shall be
prima facie evidence of the existence and amounts of the obligations therein recorded; provided
that the failure of any Lender or the Administrative Agent to maintain such accounts or any
error therein shall not in any manner affect the obligations of Borrower to repay the Loans in
accordance with their terms.

          (c) Promissory Notes. Any Lender by written notice to Borrower (with a copy to the
Administrative Agent) may request that Loans of any Class made by it be evidenced by a
promissory note. In such event, Borrower shall prepare, execute and deliver to such Lender a
promissory note payable to the order of such Lender (or, if requested by such Lender, to such
Lender and its registered assigns) in the form of Exhibit K-1, K-2 or
K-3, as the case may be. Thereafter, the Loans evidenced by such promissory note and
interest thereon shall at all times (including after assignment pursuant to Section
10.04) be represented by one or more promissory notes in such form payable to the order of
the payee named therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

     SECTION 2.05 Fees.

          (a) Commitment Fee. Borrower agrees to pay to the Administrative Agent for the
account of each Lender a commitment fee (a “Commitment Fee”) equal to the Applicable Fee per
annum on the average daily unused amount of the Revolving Commitment of such Lender during the
period from and including the Closing Date to but excluding the date on which such Commitment
terminates. Accrued Commitment Fees shall be payable in arrears (A) on the last Business Day of
March, June, September and December of each year, commencing on the first such date to occur
after the Closing Date, and (B) on the date on which such Commitment terminates. Commitment
Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). For purposes of
computing Commitment Fees, a Revolving Commitment of a Lender shall be deemed to be used to the
extent of the outstanding Revolving Loans and LC Exposure of such Lender (and the Swingline
Exposure of such Lender shall be disregarded for such purpose).

- 39 -

 

          (b) Administrative Agent Fees. Borrower agrees to pay to the Administrative Agent,
for its own account, the administrative fees set forth in the Amendment Fee Letter and/or such
other fees payable in the amounts and at the times separately agreed upon between Borrower and
the Administrative Agent (the “Administrative Agent Fees”).

          (c) LC and Fronting Fees. Borrower agrees to pay (i) to the Administrative Agent
for the account of each Revolving Lender a participation fee (“LC Participation Fee”) with
respect to its participations in Letters of Credit, which shall accrue at a rate equal to the
Applicable Margin from time to time used to determine the interest rate on Eurodollar Revolving
Loans pursuant to Section 2.06 on the average daily amount of such Lender’s LC Exposure
(excluding any portion thereof attributable to Reimbursement Obligations) during the period from
and including the Closing Date to but excluding the later of the date on which such Lender’s
Revolving Commitment terminates and the date on which such Lender ceases to have any LC
Exposure, and (ii) to the Issuing Bank a fronting fee (“Fronting Fee”), which shall accrue at
the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any
portion thereof attributable to Reimbursement Obligations) during the period from and including
the Closing Date to but excluding the later of the date of termination of the Revolving
Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing
Bank’s customary fees with respect to the issuance, amendment, renewal or extension of any
Letter of Credit or processing of drawings thereunder. Accrued LC Participation Fees and
Fronting Fees shall be payable in arrears (i) on the last Business Day of March, June, September
and December of each year, commencing on the first such date to occur after the Closing Date,
and (ii) on the date on which the Revolving Commitments terminate. Any such fees accruing after
the date on which the Revolving Commitments terminate shall be payable on demand. Any other
fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days
after demand therefor. All LC Participation Fees and Fronting Fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

          (d) All Fees shall be paid on the dates due, in immediately available funds, to the
Administrative Agent for distribution, if and as appropriate, among the Lenders, except that
Borrower shall pay the Fronting Fees directly to the Issuing Bank. Once paid, none of the Fees
shall be refundable under any circumstances.

     SECTION 2.06 Interest on Loans.

          (a) ABR Loans. Subject to the provisions of Section 2.06(c), the Loans
comprising each ABR Borrowing, including each Swingline Loan, shall bear interest at a rate per
annum equal to the Alternate Base Rate plus the Applicable Margin in effect from time to time.

          (b) Eurodollar Loans. Subject to the provisions of Section 2.06(c), the
Loans comprising each Eurodollar Borrowing shall bear interest at a rate per annum equal to the
Adjusted LIBOR Rate for the Interest Period in effect for such Borrowing plus the Applicable
Margin in effect from time to time.

- 40 -

 

          (c) Default Rate. Notwithstanding the foregoing, during the continuance of an
Event of Default, all overdue Obligations shall, to the extent permitted by applicable law, bear
interest, after as well as before judgment, at a per annum rate equal to (i) in the case of
principal of or interest on any Loan, 2% plus the rate otherwise applicable to such Loan as
provided in the preceding paragraphs of this Section 2.06 or (ii) in the case of any
other amount, 2% plus the rate otherwise applicable to such amount (in either case, the “Default
Rate”).

          (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in
arrears on each Interest Payment Date for such Loan; provided that (i) interest accrued pursuant
to Section 2.06(c) shall be payable on demand, (ii) in the event of any repayment or
prepayment of any Loan (other than a prepayment of an ABR Revolving Loan or a Swingline Loan),
accrued interest on the principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to
the end of the current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion.

          (e) Interest Calculation. All interest hereunder shall be computed on the basis of
a year of 360 days, except that interest computed by reference to the Alternate Base Rate shall
be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case
shall be payable for the actual number of days elapsed (including the first day but excluding
the last day). The applicable Alternate Base Rate or Adjusted LIBOR Rate shall be determined by
the Administrative Agent in accordance with the provisions of this Agreement and such
determination shall be conclusive absent manifest error.

     SECTION 2.07 Termination and Reduction of Commitments.

          (a) Termination of Commitments. The Revolving Commitments, the Swingline
Commitment and the LC Commitment shall automatically terminate on the Revolving Maturity Date.

          (b) Optional Terminations and Reductions. At its option, Borrower may at any time
terminate, or from time to time permanently reduce, the Commitments of any Class; provided that
(i) each reduction of the Commitments of any Class shall be in an amount that is an integral
multiple of $500,000 and not less than $1.0 million and (ii) the Revolving Commitments shall not
be terminated or reduced if, after giving effect to any concurrent prepayment of the Revolving
Loans in accordance with Section 2.10, the aggregate amount of Revolving Exposures would
exceed the aggregate amount of Revolving Commitments.

          (c) Borrower Notice. Borrower shall notify the Administrative Agent in writing of
any election to terminate or reduce the Commitments under Section 2.07(b) at least three
Business Days prior to the effective date of such termination or reduction, specifying such
election and the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by
Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of
the Commitments delivered by Borrower may state that such notice is

- 41 -

 

conditioned upon the
effectiveness of other credit facilities, in which case such notice may be revoked by
Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if
such condition is not satisfied. Any termination or reduction of the Commitments of any Class
shall be permanent. Each reduction of the Commitments of any Class shall be made ratably among
the Lenders in accordance with their respective Commitments of such Class.

     SECTION 2.08 Interest Elections.

          (a) Generally. Each Revolving Borrowing and Term Borrowing initially shall be of
the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar
Borrowing, shall have an initial Interest Period as specified in such Borrowing Request.
Thereafter, Borrower may elect to convert such Borrowing to a different Type or to continue such
Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all
as provided in this Section. Borrower may elect different options with respect to different
portions of the affected Borrowing, in which case each such portion shall be allocated ratably
among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each
such portion shall be considered a separate Borrowing. Notwithstanding anything to the
contrary, Borrower shall not be entitled to request any conversion or continuation that, if
made, would result in more than twelve Eurodollar Borrowings outstanding hereunder at any one
time. This Section shall not apply to Swingline Borrowings, which may not be converted or
continued.

          (b) Interest Election Notice. To make an election pursuant to this Section,
Borrower shall deliver, by hand delivery or telecopier, a duly completed and executed Interest
Election Request to the Administrative Agent not later than the time that a Borrowing Request
would be required under Section 2.03 if Borrower were requesting a Revolving Borrowing
or Term Borrowing of the Type resulting from such election to be made on the effective date of
such election. Each Interest Election Request shall be irrevocable. Each Interest Election
Request shall specify the following information in compliance with Section 2.02:

          (i) the Borrowing to which such Interest Election Request applies and, if different
options are being elected with respect to different portions thereof, or if outstanding
Borrowings are being combined, allocation to each resulting Borrowing (in which case the
information to be specified pursuant to clauses (iii) and (iv) below shall be specified for
each resulting Borrowing);

          (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day;

          (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and

- 42 -

 

          (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period
contemplated by the definition of the term “Interest Period”.

          If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then Borrower shall be deemed to have selected an Interest Period of one month’s
duration.

          Promptly following receipt of an Interest Election Request, the Administrative Agent shall
advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

          (c) Automatic Conversion to ABR Borrowing. If an Interest Election Request with
respect to a Eurodollar Borrowing is not timely delivered prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end
of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding
any contrary provision hereof, if an Event of Default has occurred and is continuing, the
Administrative Agent or the Required Lenders may require, by notice to Borrower, that (i) no
outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless
repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

     SECTION 2.09 [Intentionally Omitted]

     SECTION 2.10 Optional and Mandatory Prepayments of Loans.

          (a) Optional Prepayments. Borrower shall have the right at any time and from time
to time to prepay any Borrowing, in whole or in part, subject to the requirements of this
Section 2.10; provided that each partial prepayment shall be in an amount that is an
integral multiple of $500,000 and not less than $1.0 million.

          (b) Revolving Loan Prepayments.

          (i) In the event of the termination of all the Revolving Commitments, Borrower shall,
on the date of such termination, repay or prepay all its outstanding Revolving Borrowings
and all outstanding Swingline Loans and replace all outstanding Letters of Credit or cash
collateralize all outstanding Letters of Credit in accordance with the procedures set forth
in Section 2.18(i).

          (ii) In the event of any partial reduction of the Revolving Commitments, then (x) at or
prior to the effective date of such reduction, the Administrative Agent shall notify
Borrower and the Revolving Lenders of the sum of the Revolving Exposures after giving effect
thereto and (y) if the sum of the Revolving Exposures would exceed the aggregate amount of
Revolving Commitments after giving
effect to such reduction, then Borrower shall, on the date of such reduction, first,
repay or prepay Swingline Loans, second, repay or prepay Revolving Borrowings and third,

- 43 -

 

replace outstanding Letters of Credit or cash collateralize outstanding Letters of Credit in
accordance with the procedures set forth in Section 2.18(i), in an aggregate amount
sufficient to eliminate such excess.

          (iii) In the event that the sum of all Lenders’ Revolving Exposures exceeds the
Revolving Commitments then in effect, Borrower shall, without notice or demand, immediately
first, repay or prepay Revolving Borrowings, and second, replace outstanding Letters of
Credit or cash collateralize outstanding Letters of Credit in accordance with the procedures
set forth in Section 2.18(i), in an aggregate amount sufficient to eliminate such
excess.

          (iv) In the event that the aggregate LC Exposure exceeds the LC Commitment then in
effect, Borrower shall, without notice or demand, immediately replace outstanding Letters of
Credit or cash collateralize outstanding Letters of Credit in accordance with the procedures
set forth in Section 2.18(i), in an aggregate amount sufficient to eliminate such
excess.

          (c) Asset Sales. Not later than five Business Days following the receipt of any
Net Cash Proceeds of any Asset Sale by Borrower or any of its Subsidiaries, Borrower shall make
prepayments in accordance with Sections 2.10(e) and (f) in an aggregate amount
equal to 100% of such Net Cash Proceeds; provided that:

          (i) no such prepayment shall be required under this Section 2.10(c) with
respect to (A) any Asset Sale permitted by Sections 6.06(a), (c)-(h),
(j) and (k), (B) the disposition of property which constitutes a Casualty
Event, or (C) Asset Sales for fair market value resulting in no more than $20.0 million in
Net Cash Proceeds per Asset Sale (or series of related Asset Sales); and

          (ii) so long as no Default shall then exist or would arise therefrom, such proceeds
shall not be required to be so applied on such date to the extent that the Ultimate General
Partner shall have delivered an Officers’ Certificate to the Administrative Agent on or
prior to such date stating that such Net Cash Proceeds are expected to be reinvested in
fixed or capital assets within 360 days following the date of such Asset Sale (which
Officers’ Certificate shall set forth the estimates of the proceeds to be so expended);
provided that if all or any portion of such Net Cash Proceeds is not so reinvested within
such 360-day period, such unused portion shall be applied on the last day of such period as
a mandatory prepayment as provided in this Section 2.10(c); provided, further, that
if the property subject to such Asset Sale constituted Collateral, then all property
purchased with the Net Cash Proceeds thereof pursuant to this subsection shall be made
subject to the Lien of the applicable Security Documents in favor of the Collateral Agent,
for its benefit and for the benefit of the other Secured Parties in accordance with
Sections 5.11 and 5.12.

          (d) Casualty Events. Not later than seven Business Days following the receipt of
any Net Cash Proceeds from a Casualty Event by Borrower or any of its Subsidiaries,

- 44 -

 

Borrower shall make prepayments in accordance with Sections 2.10(e) and (f)
in an aggregate amount equal to 100% of such Net Cash Proceeds; provided that:

          (i) no such payment shall be required under this Section 2.10(d) with respect
to any Casualty Event (or series of related Casualty Events) resulting in $20.0 million or
less in Net Cash Proceeds;

          (ii) so long as no Default shall then exist or arise therefrom, such proceeds shall not
be required to be so applied on such date to the extent that the Ultimate General Partner
shall have delivered an Officers’ Certificate to the Administrative Agent on or prior to
such date stating that such proceeds are expected to be used to repair, replace or restore
any property in respect of which such Net Cash Proceeds were paid or to reinvest in other
fixed or capital assets, no later than 360 days following the date of receipt of such
proceeds; provided that so long as construction or other work to so replace, repair or
restore has commenced within such 360-day period but has not been completed (and can
reasonably be expected to be completed pursuant to a written contract to be completed within
540 days of receipt), any such remaining proceeds shall continue to not be required to be so
applied so long as they are used to repay any outstanding Revolving Loans; provided further
that if the property subject to such Casualty Event constituted Collateral under the
Security Documents, then all property purchased with the Net Cash Proceeds thereof pursuant
to this subsection shall be made subject to the Lien of the applicable Security Documents in
favor of the Collateral Agent, for its benefit and for the benefit of the other Secured
Parties in accordance with Sections 5.11 and 5.12; and

          (iii) if any portion of such Net Cash Proceeds shall not be so applied within such
360-day period (or 540-day period, as applicable), such unused portion shall be applied on
the last day of such period as a mandatory prepayment as provided in this Section
2.10(d).

          (e) Application of Prepayments. Prior to any optional or mandatory prepayment
hereunder, Borrower shall select the Borrowing or Borrowings to be prepaid and shall specify
such selection in the notice of such prepayment pursuant to Section 2.10(f), subject to
the provisions of this Section 2.10(e). After application of mandatory prepayments of
Term Loans described above in this Section 2.10(e) and to the extent there are mandatory
prepayment amounts remaining after such application, the Revolving Commitments shall be
permanently reduced ratably among the Revolving Lenders in accordance with their applicable
Revolving Commitments in an aggregate amount equal to such excess, and Borrower shall comply
with Section 2.10(b).

          Amounts to be applied pursuant to this Section 2.10 to the prepayment of Term Loans
and Revolving Loans shall be applied, as applicable, first to reduce outstanding ABR Term Loans and
ABR Revolving Loans, respectively. Any amounts remaining after each such application shall be
applied to prepay Eurodollar Term Loans or Eurodollar Revolving Loans, as applicable.
Notwithstanding the foregoing, if the amount of any prepayment of Loans required under this
Section 2.10 shall be in excess of the amount of the ABR Loans at the time

-45-

 

outstanding (an “Excess Amount”), only the portion of the amount of such prepayment as is
equal to the amount of such outstanding ABR Loans shall be immediately prepaid and, at the election
of Borrower, the Excess Amount shall be either (A) deposited in an escrow account on terms
satisfactory to the Collateral Agent and applied to the prepayment of Eurodollar Loans on the last
day of the then next-expiring Interest Period for Eurodollar Loans; provided that (i) interest in
respect of such Excess Amount shall continue to accrue thereon at the rate provided hereunder for
the Loans which such Excess Amount is intended to repay until such Excess Amount shall have been
used in full to repay such Loans and (ii) at any time while an Event of Default has occurred and is
continuing, the Administrative Agent may, and upon written direction from the Required Lenders
shall, apply any or all proceeds then on deposit to the payment of such Loans in an amount equal to
such Excess Amount or (B) prepaid immediately, together with any amounts owing to the Lenders under
Section 2.13.

          (f) Notice of Prepayment. Borrower shall notify the Administrative Agent (and, in
the case of prepayment of a Swingline Loan, the Swingline Lender) by written notice of any
prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than
11:00 a.m., New York City time, three Business Days before the date of prepayment, (ii) in the
case of prepayment of an ABR Borrowing, not later than four hours (during the normal Business
Day) prior to such prepayment and (iii) in the case of prepayment of a Swingline Loan, not later
than 11:00 a.m., New York City time, on the date of prepayment. Each such notice shall be
irrevocable; provided that, if a notice of prepayment is given in connection with a conditional
notice of termination of the Commitments as contemplated by Section 2.07, then such
notice of prepayment may be revoked if such termination is revoked in accordance with
Section 2.07. Each such notice shall specify the prepayment date, the principal amount
of each Borrowing or portion thereof to be prepaid and, in the case of a mandatory prepayment, a
reasonably detailed calculation of the amount of such prepayment. Promptly following receipt of
any such notice (other than a notice relating solely to Swingline Loans), the Administrative
Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any
Borrowing shall be in an amount that would be permitted in the case of a Credit Extension of the
same Type as provided in Section 2.02, except as necessary to apply fully the required
amount of a mandatory prepayment. Each prepayment of a Borrowing shall be applied ratably to
the Loans included in the prepaid Borrowing and otherwise in accordance with this Section
2.10. Prepayments shall be accompanied by accrued interest to the extent required by
Section 2.06.

     SECTION 2.11 Alternate Rate of Interest. If prior to the commencement of any Interest
Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be final and conclusive
absent manifest error) that adequate and reasonable means do not exist for ascertaining the
Adjusted LIBOR Rate for such Interest Period; or

          (b) the Administrative Agent is advised in writing by the Required Lenders that the
Adjusted LIBOR Rate for such Interest Period will not adequately and fairly reflect

-46-

 

the cost to such Lenders of making or maintaining their Loans included in such Borrowing
for such Interest Period;

then the Administrative Agent shall give written notice thereof to Borrower and the Lenders as
promptly as practicable thereafter and, until the Administrative Agent notifies Borrower and the
Lenders that the circumstances giving rise to such notice no longer exist (which notice shall be
promptly given), (i) any Interest Election Request that requests the conversion of any Borrowing
to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if
any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR
Borrowing.

     SECTION 2.12 Yield Protection.

          (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
reflected in the Adjusted LIBOR Rate) or the Issuing Bank;

          (ii) subject any Lender or the Issuing Bank 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 Loan made by it, or change the basis of taxation of payments to such Lender or the
Issuing Bank in respect thereof (except for Indemnified Taxes or Other Taxes covered by
Section 2.15 and the imposition of, or any change in the rate of, any Excluded Tax
payable by such Lender or the Issuing Bank); or

          (iii) impose on any Lender or the Issuing Bank or the London interbank market any other
condition, cost or expense (excluding Taxes) affecting this Agreement or Eurodollar 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 Loan (or of maintaining its obligation to make any such Loan), or to
increase the cost to such Lender, the Issuing Bank or such Lender’s or the Issuing Bank’s holding
company, if any, of participating in, issuing or maintaining any Letter of Credit (or of
maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the
amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of
principal, interest or any other amount), then, upon request of such Lender or the Issuing Bank,
Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or
amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional
costs incurred or reduction suffered.

          (b) Capital Requirements. If any Lender or the Issuing Bank determines (in good
faith, but in its sole absolute discretion) that any Change in Law affecting such Lender or the
Issuing Bank or any lending office of such Lender or such Lender’s or the Issuing Bank’s holding
company, if any, regarding capital requirements has or would have the effect

-47-

 

of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the
capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this
Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of
Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level
below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding
company could have achieved but for such Change in Law (taking into consideration such Lender’s
or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding
company with respect to capital adequacy), then from time to time Borrower will pay to such
Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will
compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding
company for any such reduction suffered.

          (c) Certificates for Reimbursement. A certificate of a Lender or the Issuing Bank
setting forth in reasonable detail the amount or amounts necessary to compensate such Lender or
the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or
(b) of this Section 2.12 and delivered to Borrower shall be conclusive absent manifest
error. Subject to Section 2.12(d), Borrower shall pay such Lender or the Issuing Bank,
as the case may be, the amount shown as due on any such certificate within 10 days after receipt
thereof.

          (d) Delay in Requests. Failure or delay on the part of any Lender or the Issuing
Bank to demand compensation pursuant to this Section 2.12 shall not constitute a waiver
of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that Borrower
shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for
any increased costs incurred or reductions suffered more than six months prior to the date that
such Lender or the Issuing Bank, as the case may be, notifies Borrower of the Change in Law
giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’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 six-month period referred to above shall
be extended to include the period of retroactive effect thereof) .

     SECTION 2.13 Breakage Payments. In the event of (a) the payment or prepayment, whether
optional or mandatory, of any principal of any Eurodollar Loan earlier than the last day of an
Interest Period applicable thereto (including as a result of an Event of Default), (b) the
conversion of any Eurodollar Loan earlier than the last day of the Interest Period applicable
thereto, (c) the failure to borrow, convert, continue or prepay any Revolving Loan or Term Loan on
the date specified in any notice delivered pursuant hereto or (d) the assignment of any Eurodollar
Loan earlier than the last day of the Interest Period applicable thereto as a result of a request
by Borrower pursuant to Section 2.16(b), then, in any such event, Borrower shall compensate
each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar
Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by
such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the
principal amount of such Loan had such event not occurred, at the Adjusted LIBOR Rate that would
have been applicable to such Loan, for the period from the date of such event to the last day of
the then current Interest Period therefor (or, in the case of a failure to

-48-

 

borrow, convert or continue, for the period that would have been the Interest Period for such
Loan), over (ii) the amount of interest which would accrue on such principal amount for such period
at the interest rate which such Lender would bid were it to bid, at the commencement of such
period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar
market. A certificate of any Lender setting forth in reasonable detail any amount or amounts that
such Lender is entitled to receive pursuant to this Section 2.13 shall be delivered to
Borrower (with a copy to the Administrative Agent) and shall be conclusive and binding absent
manifest error. Borrower shall pay such Lender the amount shown as due on any such certificate
within 5 days after receipt thereof.

     SECTION 2.14 Payments Generally; Pro Rata Treatment; Sharing of Setoffs.

          (a) Payments Generally. Borrower shall make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest, fees or
Reimbursement Obligations, or of amounts payable under Section 2.12, 2.13,
2.15 or 10.03, or otherwise) on or before the time expressly required hereunder
or under such other Loan Document for such payment (or, if no such time is expressly required,
prior to 2:00 p.m., New York City time), on the date when due, in immediately available funds,
without setoff, deduction or counterclaim. Any amounts received after such time on any date
may, in the discretion of the Administrative Agent, be deemed to have been received on the next
succeeding Business Day for purposes of calculating interest thereon. All such payments shall
be made to the Administrative Agent at its offices at 677 Washington Boulevard, Stamford,
Connecticut, except payments to be made directly to the Issuing Bank or Swingline Lender as
expressly provided herein and except that payments pursuant to Sections 2.12,
2.13, 2.15 and 10.03 shall be made directly to the persons entitled
thereto and payments pursuant to other Loan Documents shall be made to the persons specified
therein. The Administrative Agent shall distribute any such payments received by it for the
account of any other person to the appropriate recipient promptly following receipt thereof. If
any payment under any Loan Document shall be due on a day that is not a Business Day, unless
specified otherwise, the date for payment shall be extended to the next succeeding Business Day,
and, in the case of any payment accruing interest, interest thereon shall be payable for the
period of such extension. All payments under each Loan Document shall be made in dollars,
except as expressly specified otherwise.

          (b) Insufficient Funds. If at any time insufficient funds are received by and
available to the Administrative Agent to pay fully all amounts of principal, Reimbursement
Obligations, interest and fees then due hereunder, such funds shall be applied (i) first, toward
payment of interest and fees then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of interest and fees then due to such parties, and (ii) second,
toward payment of principal and Reimbursement Obligations then due hereunder, ratably among the
parties entitled thereto in accordance with the amounts of principal and Reimbursement
Obligations then due to such parties.

          (c) Sharing of Setoff. If any Lender (and/or the Issuing Bank, which shall be
deemed a “Lender” for purposes of this Section 2.14(c)) shall, by exercising any right
of

-49-

 

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

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

          (ii) the provisions of this paragraph shall not be construed to apply to (x) any
payment made by 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 participations in LC Disbursements to any
assignee or participant, other than to Borrower or any Subsidiary thereof (as to which the
provisions of this paragraph shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under
applicable Requirements of Law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against such Loan Party rights of setoff and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of such Loan Party in the
amount of such participation. If under applicable bankruptcy, insolvency or any similar law any
Secured Party receives a secured claim in lieu of a setoff or counterclaim to which this
Section 2.14(c) applies, such Secured Party shall to the extent practicable, exercise its
rights in respect of such secured claim in a manner consistent with the rights to which the Secured
Party is entitled under this Section 2.14(c) to share in the benefits of the recovery of
such secured claim.

          (d) Borrower Default. Unless the Administrative Agent shall have received notice
from Borrower prior to the date on which any payment is due to the Administrative Agent for the
account of the Lenders or the Issuing Bank hereunder that Borrower will not make such payment,
the Administrative Agent may assume that Borrower has made such payment on such date in
accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the
Issuing Bank, as the case may be, the amount due. In such event, if Borrower has not in fact
made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally
agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to
such Lender or the Issuing Bank with interest thereon, for each day from and including the date
such amount is distributed to it to but excluding the date of payment to the Administrative
Agent, at the greater of the Federal Funds Effective

-50-

 

Rate and a rate determined by the Administrative Agent in accordance with banking industry
rules on interbank compensation.

          (e) Lender Default. If any Lender shall fail to make any payment required to be
made by it pursuant to Section 2.02(c), 2.14(d), 2.17(d),
2.18(d), 2.18(e) or 10.03(c), then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Lender to satisfy such Lender’s
obligations under such Sections until all such unsatisfied obligations are fully paid.

     SECTION 2.15 Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of any
obligation of 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 Borrower shall be required by applicable Requirements of 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 Issuing Bank, as
the case may be, receives an amount equal to the sum it would have received had no such
deductions been made, (ii) Borrower shall make such deductions and (iii) Borrower shall timely
pay the full amount deducted to the relevant Governmental Authority in accordance with
applicable Requirements of Law.

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

          (c) Indemnification by Borrower. Borrower shall indemnify the Administrative
Agent, each Lender and the Issuing Bank, within 20 days after demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes
imposed or asserted on or attributable to amounts payable under this Section) paid by the
Administrative Agent, such Lender or the Issuing Bank, 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 Borrower by a Lender or the Issuing Bank (with a copy to the Administrative Agent), or by the
Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be
conclusive absent manifest error.

          (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by Borrower to a Governmental Authority, 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.

-51-

 

          (e) Status of Lenders. Any Foreign Lender shall, to the extent it may lawfully do
so, deliver to 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 Borrower or
the Administrative Agent or if the Lender’s factual or legal circumstances have changed since it
last provided the form, rendering such form obsolete or incorrect, 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 of America is a party,

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

          (iii) in the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under Section 881(c) of the Code, (x) a certificate, in substantially the
form of Exhibit N, or any other form approved by the Administrative Agent, 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 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 Requirements of 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
Requirements of Law to permit Borrower to determine the withholding or deduction required to
be made.

          (f) Treatment of Certain Refunds. If the Administrative Agent, a Lender or the
Issuing Bank determines, in its good faith sole discretion, that it has received a refund of any
Indemnified Taxes or Other Taxes as to which it has been indemnified by Borrower or with respect
to which Borrower has paid additional amounts pursuant to this Section, it shall pay to Borrower
an amount equal to such refund (but only to the extent of indemnity payments made, or additional
amounts paid, by Borrower under this Section with respect to the Indemnified Taxes or Other
Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative
Agent, such Lender or the Issuing Bank, as the case may be, and without interest (other than any
interest paid by the relevant Governmental Authority with respect to such refund) so as to leave
such Lender, Issuing Bank or Administrative Agent in no better or worse position than in which
each would have been if payment of the relevant additional amount had not been made; provided
that Borrower, upon the request of the Administrative Agent, such Lender or the Issuing Bank,
agrees to repay the amount paid over to Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or the
Issuing Bank in the event the Administrative Agent, such Lender or the Issuing Bank is required
to repay such refund to such Governmental Authority. This paragraph shall not be construed to
require the

-52-

 

Administrative Agent, any Lender or the Issuing Bank to make available its tax returns (or
any other information relating to its taxes that it deems confidential) to Borrower or any other
person.

     SECTION 2.16 Mitigation Obligations; Replacement of Lenders.

          (a) Designation of a Different Lending Office. If any Lender requests compensation
under Section 2.12, or requires Borrower to pay any additional amount to any Lender or
any Governmental Authority for the account of any Lender pursuant to Section 2.15, then
such Lender shall use reasonable efforts to designate a different lending office for funding or
booking its Loans hereunder or to assign its rights and obligations hereunder to another of its
offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or
2.15, as the case may be and (ii) would not subject such Lender to any unreimbursed cost
or expense and would not otherwise be disadvantageous to such Lender. Borrower hereby agrees to
pay all reasonable costs and expenses incurred by any Lender in connection with any such
designation or assignment. A certificate setting forth such costs and expenses submitted by
such Lender to Borrower shall be conclusive absent manifest error.

          (b) Replacement of Lenders. If any Lender requests compensation under Section
2.12, or if Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.15, or if any
Lender defaults in its obligation to fund Loans hereunder, or if Borrower exercises its
replacement rights under Section 10.02(d), then 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 10.04), all of its interests, rights and obligations
under this Agreement and the other Loan Documents to an assignee that shall assume such
obligations (which assignee may be another Lender, if a Lender accepts such assignment);
provided that:

          (i) Borrower shall have paid to the Administrative Agent the processing and recordation
fee specified in Section 10.04(b);

          (ii) such Lender shall have received payment of an amount equal to the outstanding
principal of its Loans and participations in LC Disbursements and Swingline Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder and under the
other Loan Documents (including any amounts under Section 2.13), from the assignee
(to the extent of such outstanding principal and accrued interest and fees) or Borrower (in
the case of all other amounts);

          (iii) in the case of any such assignment resulting from a claim for compensation under
Section 2.12 or payments required to be made pursuant to Section 2.15, such
assignment will result in a reduction in such compensation or payments thereafter; and

-53-

 

          (iv) such assignment does not conflict with applicable Requirements of Law.

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 Borrower to require
such assignment and delegation cease to apply.

     SECTION 2.17 Swingline Loans.

          (a) Swingline Commitment. Subject to the terms and conditions set forth herein,
the Swingline Lender agrees to make Swingline Loans to Borrower from time to time during the
Revolving Availability Period, in an aggregate principal amount at any time outstanding that
will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding
$10.0 million or (ii) the sum of the total Revolving Exposures exceeding the total Revolving
Commitments; provided that the Swingline Lender shall not be required to make a Swingline Loan
to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the
terms and conditions set forth herein, Borrower may borrow, repay and reborrow Swingline Loans.

          (b) Swingline Loans. To request a Swingline Loan, Borrower shall deliver, by hand
delivery or telecopier, a duly completed and executed Borrowing Request to the Administrative
Agent and the Swingline Lender, not later than 2:00 p.m., New York City time, on the day of a
proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested
date (which shall be a Business Day) and the amount of the requested Swingline Loan. Each
Swingline Loan shall be an ABR Loan. The Swingline Lender shall make each Swingline Loan
available to Borrower by means of a credit to the general deposit account of Borrower with the
Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC
Disbursement as provided in Section 2.18(e), by remittance to the Issuing Bank) by 3:00
p.m., New York City time, on the requested date of such Swingline Loan. Borrower shall not
request a Swingline Loan if at the time of or immediately after giving effect to the Extension
of Credit contemplated by such request a Default has occurred and is continuing or would result
therefrom. Swingline Loans shall be made in minimum amounts of $500,000 and integral multiples
of $500,000 above such amount.

          (c) Prepayment. Borrower shall have the right at any time and from time to time to
repay any Swingline Loan, in whole or in part, upon giving written notice to the Swingline
Lender and the Administrative Agent before 12:00 (noon), New York City time, on the proposed
date of repayment.

          (d) Participations. The Swingline Lender may at any time in its discretion by
written notice given to the Administrative Agent (provided such notice requirement shall not
apply if the Swingline Lender and the Administrative Agent are the same entity) not later than
11:00 a.m., New York City time, on the next succeeding Business Day following such notice
require the Revolving Lenders to acquire participations on such Business Day in all or a portion
of the Swingline Loans then outstanding. Such notice shall specify the aggregate

-54-

 

amount of Swingline Loans in which Revolving Lenders will participate. Promptly upon
receipt of such notice, the Administrative Agent will give notice thereof to each Revolving
Lender, specifying in such notice such Lender’s Pro Rata Percentage of such Swingline Loan or
Loans. Each Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of
notice as provided above, to pay to the Administrative Agent, for the account of the Swingline
Lender, such Lender’s Pro Rata Percentage of such Swingline Loan or Loans. Each Revolving
Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans
pursuant to this paragraph is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever (so long as such payment shall not cause such
Lender’s Revolving Exposure to exceed such Lender’s Revolving Commitment). Each Revolving
Lender shall comply with its obligation under this paragraph by wire transfer of immediately
available funds, in the same manner as provided in Section 2.02(c) with respect to Loans
made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment
obligations of the Revolving Lenders), and the Administrative Agent shall promptly pay to the
Swingline Lender the amounts so received by it from the Revolving Lenders. The Administrative
Agent shall notify Borrower of any participations in any Swingline Loan acquired by the
Revolving Lenders pursuant to this paragraph, and thereafter payments in respect of such
Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any
amounts received by the Swingline Lender from Borrower (or other party on behalf of Borrower) in
respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of
participations therein shall be promptly remitted to the Administrative Agent. Any such amounts
received by the Administrative Agent shall be promptly remitted by the Administrative Agent to
the Revolving Lenders that shall have made their payments pursuant to this paragraph, as their
interests may appear. The purchase of participations in a Swingline Loan pursuant to this
paragraph shall not relieve Borrower of any default in the payment thereof.

     SECTION 2.18 Letters of Credit.

          (a) General. Subject to the terms and conditions set forth herein, Borrower may
request the Issuing Bank, and the Issuing Bank agrees, to issue Letters of Credit for its own
account or the account of a Subsidiary in a form reasonably acceptable to the Administrative
Agent and the Issuing Bank, at any time and from time to time during the Revolving Availability
Period (provided that Borrower shall be a co-applicant, and be jointly and severally liable,
with respect to each Letter of Credit issued for the account of a Subsidiary). The Issuing Bank
shall have no obligation to issue, and Borrower shall not request the issuance of, any Letter of
Credit at any time if after giving effect to such issuance, the LC Exposure would exceed the LC
Commitment or the total Revolving Exposure would exceed the total Revolving Commitments. In the
event of any inconsistency between the terms and conditions of this Agreement and the terms and
conditions of any form of letter of credit application or other agreement submitted by Borrower
to, or entered into by Borrower

-55-

 

with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this
Agreement shall control.

          (b) Request for Issuance, Amendment, Renewal, Extension; Certain Conditions and
Notices. To request the issuance of a Letter of Credit or the amendment, renewal or
extension of an outstanding Letter of Credit, Borrower shall deliver, by hand or telecopier (or
transmit by electronic communication, if arrangements for doing so have been approved by the
Issuing Bank), an LC Request to the Issuing Bank and the Administrative Agent not later than
11:00 a.m. on the third Business Day preceding the requested date of issuance, amendment,
renewal or extension (or such later date and time as is acceptable to the Issuing Bank).

          A request for an initial issuance of a Letter of Credit shall specify in form and detail
satisfactory to the Issuing Bank:

          (i) the proposed issuance date of the requested Letter of Credit (which shall be a
Business Day);

          (ii) the amount thereof;

          (iii) the expiry date thereof (which shall not be later than the date specified in
Section 2.18(c));

          (iv) the name and address of the beneficiary thereof;

          (v) whether the Letter of Credit is to be issued for its own account or for the account
of one of its Subsidiaries (provided that Borrower shall be a co-applicant, and therefore
jointly and severally liable, with respect to each Letter of Credit issued for the account
of a Subsidiary);

          (vi) the documents to be presented by such beneficiary in connection with any drawing
thereunder;

          (vii) the full text of any certificate to be presented by such beneficiary in
connection with any drawing thereunder; and

          (viii) such other matters as the Issuing Bank may require.

          A request for an amendment, renewal or extension of any outstanding Letter of Credit shall
specify in form and detail satisfactory to the Issuing Bank:

          (i) the Letter of Credit to be amended, renewed or extended;

          (ii) the proposed date of amendment, renewal or extension thereof (which shall be a
Business Day);

          (iii) the nature of the proposed amendment, renewal or extension; and

-56-

 

          (iv) such other matters as the Issuing Bank may require.

If requested by the Issuing Bank, Borrower also shall submit a letter of credit application on the
Issuing Bank’s standard form in connection with any request for a Letter of Credit. In the event
of any conflict between such application and this Agreement, this Agreement shall control. A
Letter of Credit shall be issued, amended, renewed or extended only if (and, upon issuance,
amendment, renewal or extension of each Letter of Credit, Borrower shall be deemed to represent and
warrant that), after giving effect to such issuance, amendment, renewal or extension, (i) the LC
Exposure shall not exceed the LC Commitment, (ii) the total Revolving Exposures shall not exceed
the total Revolving Commitments and (iii) the conditions set forth in Section 4.02 in
respect of such issuance, amendment, renewal or extension shall have been satisfied. Unless the
Issuing Bank shall agree otherwise, no Letter of Credit shall be in an initial amount less than
$100,000, in the case of a Commercial Letter of Credit, or $500,000, in the case of a Standby
Letter of Credit.

          Upon the issuance of any Letter of Credit or amendment, renewal, extension or modification to
a Letter of Credit, the Issuing Bank shall promptly notify the Administrative Agent, who shall
promptly notify each Revolving Lender, thereof, which notice shall be accompanied by a copy of such
Letter of Credit or amendment, renewal, extension or modification to a Letter of Credit and the
amount of such Lender’s respective participation in such Letter of Credit pursuant to Section
2.18(d). On the first Business Day of each calendar month, the Issuing Bank shall provide to
the Administrative Agent a report listing all outstanding Letters of Credit and the amounts and
beneficiaries thereof and the Administrative Agent shall promptly provide such report to each
Revolving Lender.

          (c) Expiration Date.

          (i) Each Letter of Credit shall expire at or prior to the close of business on the
earlier of (A) in the case of a Standby Letter of Credit, (x) the date which is one year
after the date of the issuance of such Standby Letter of Credit (or, in the case of any
renewal or extension thereof, one year after such renewal or extension) and (y) the Letter
of Credit Expiration Date and (B) in the case of a Commercial Letter of Credit, (x) the date
that is 270 days after the date of issuance of such Commercial Letter of Credit (or, in the
case of any renewal or extension thereof, 270 days after such renewal or extension) and (y)
the Letter of Credit Expiration Date.

          (ii) If Borrower so requests in any Letter of Credit Request, the Issuing Bank may, in
its sole and absolute discretion, agree to issue a Letter of Credit that has automatic
renewal provisions (each, an “Auto-Renewal Letter of Credit”); provided that any such
Auto-Renewal Letter of Credit must permit the Issuing Bank to prevent any such renewal 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 in each
such twelve-month period to be agreed upon at the time such Letter of Credit is issued.
Unless otherwise directed by the Issuing Bank, Borrower shall not be required to make a
specific request to the Issuing Bank for any such renewal. Once an Auto-Renewal Letter of
Credit has been issued, the Revolving Lenders shall be

-57-

 

deemed to have authorized (but may not require) the Issuing Bank to permit the renewal
of such Letter of Credit at any time to an expiry date not later than the earlier of (i) one
year from the date of such renewal and (ii) the Letter of Credit Expiration Date; provided
that the Issuing Bank shall not permit any such renewal if (x) the Issuing Bank has
determined that it would have no obligation at such time to issue such Letter of Credit in
its renewed form under the terms hereof (by reason of the provisions of Section
2.18(f) or otherwise), or (y) it has received notice on or before the day that is two
Business Days before the date which has been agreed upon pursuant to the proviso of the
first sentence of this paragraph, (A) from the Administrative Agent that any Revolving
Lender directly affected thereby has elected not to permit such renewal or (B) from the
Administrative Agent, any Lender or Borrower that one or more of the applicable conditions
specified in Section 4.02 are not then satisfied.

          (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of
the Issuing Bank or the Lenders, the Issuing Bank hereby irrevocably grants to each Revolving
Lender, and each Revolving Lender hereby acquires from the Issuing Bank, a participation in such
Letter of Credit equal to such Revolving Lender’s Pro Rata Percentage of the aggregate amount
available to be drawn under such Letter of Credit. In consideration and in furtherance of the
foregoing, each Revolving Lender hereby absolutely and unconditionally agrees to pay to the
Administrative Agent, for the account of the Issuing Bank, such Revolving Lender’s Pro Rata
Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by Borrower on
the date due as provided in Section 2.18(e), or of any reimbursement payment required to
be refunded to Borrower for any reason. Each Revolving Lender acknowledges and agrees that its
obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit
is absolute and unconditional and shall not be affected by any circumstance whatsoever,
including any amendment, renewal or extension of any Letter of Credit or the occurrence and
continuance of a Default or reduction or termination of the Commitments, or expiration,
termination or cash collateralization of any Letter of Credit and that each such payment shall
be made without any offset, abatement, withholding or reduction whatsoever.

          (e) Reimbursement.

          (i) If the Issuing Bank shall make any LC Disbursement in respect of a Letter of
Credit, Borrower shall reimburse such LC Disbursement by paying to the Issuing Bank an
amount equal to such LC Disbursement not later than 3:00 p.m., New York City time,
on the date that such LC Disbursement is made if Borrower shall have received notice of such
LC Disbursement prior to 11:00 a.m., New York City time, on such date, or, if such notice
has not been received by Borrower prior to such time on such date, then not later than 3:00
p.m., New York City time, on the Business Day immediately following the day that Borrower
receives such notice; provided that Borrower may, subject to the conditions to borrowing set
forth herein, request in accordance with Section 2.03 that such payment be financed
with ABR Revolving Loans or Swingline Loans in an equivalent amount and, to the extent so
financed, Borrower’s

-58-

 

obligation to make such payment shall be discharged and replaced by the resulting ABR
Revolving Loans or Swingline Loans.

          (ii) If Borrower fails to make such payment when due, the Issuing Bank shall notify the
Administrative Agent and the Administrative Agent shall notify each Revolving Lender of the
applicable LC Disbursement, the payment then due from Borrower in respect thereof and such
Revolving Lender’s Pro Rata Percentage thereof. Each Revolving Lender shall pay by wire
transfer of immediately available funds to the Administrative Agent not later than 2:00
p.m., New York City time, on such date (or, if such Revolving Lender shall have received
such notice later than 12:00 noon, New York City time, on any day, not later than 11:00
a.m., New York City time, on the immediately following Business Day), an amount equal to
such Revolving Lender’s Pro Rata Percentage of the unreimbursed LC Disbursement in the same
manner as provided in Section 2.02(c) with respect to Revolving Loans made by such
Revolving Lender, and the Administrative Agent will promptly pay to the Issuing Bank the
amounts so received by it from the Revolving Lenders. The Administrative Agent will
promptly pay to the Issuing Bank any amounts received by it from Borrower pursuant to the
above paragraph prior to the time that any Revolving Lender makes any payment pursuant to
the preceding sentence and any such amounts received by the Administrative Agent from
Borrower thereafter will be promptly remitted by the Administrative Agent to the Revolving
Lenders that shall have made such payments and to the Issuing Bank, as appropriate.

          (iii) If any Revolving Lender shall not have made its Pro Rata Percentage of such LC
Disbursement available to the Administrative Agent as provided above, each of such Revolving
Lender and Borrower severally agrees to pay interest on such amount, for each day from and
including the date such amount is required to be paid in accordance with the foregoing to
but excluding the date such amount is paid, to the Administrative Agent for the account of
the Issuing Bank at (A) in the case of Borrower, the rate per annum set forth in Section
2.18(h) and (B) in the case of such Lender, at a rate determined by the Administrative
Agent in accordance with banking industry rules or practices on interbank compensation.

          (f) Obligations Absolute. The Reimbursement Obligation of Borrower as provided in
Section 2.18(e) shall be absolute, unconditional and irrevocable, and shall be paid and
performed strictly in accordance with the terms of this Agreement under any and all
circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein; (ii) any draft or other
document presented under a Letter of Credit being proved to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate in any respect;
(iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or
other document that fails to comply with the terms of such Letter of Credit; (iv) any other
event or circumstance whatsoever, whether or not similar to any of the foregoing, that might,
but for the provisions of this Section 2.18, constitute a legal or equitable discharge
of, or provide a right of setoff against, the obligations of Borrower hereunder; (v) the fact
that a Default shall have occurred and be continuing; or (vi) any material adverse change in the

-59-

 

business, property, results of operations, prospects or condition, financial or otherwise,
of Borrower and its Subsidiaries. None of the Agents, the Lenders, the Issuing Bank or any of
their Affiliates shall have any liability or responsibility by reason of or in connection with
the issuance or transfer of any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or
any error, omission, interruption, loss or delay in transmission or delivery of any draft,
notice or other communication under or relating to any Letter of Credit (including any document
required to make a drawing thereunder), any error in interpretation of technical terms or any
consequence arising from causes beyond the control of the Issuing Bank; provided that the
foregoing shall not be construed to excuse the Issuing Bank from liability to Borrower to the
extent of any direct damages (as opposed to consequential damages, claims in respect of which
are hereby waived by Borrower to the extent permitted by applicable Requirements of Law)
suffered by Borrower that are caused by the Issuing Bank’s failure to exercise care when
determining whether drafts and other documents presented under a Letter of Credit comply with
the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence
or willful misconduct on the part of the Issuing Bank (as finally determined by a court of
competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such
determination. In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their face to be in
substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole
discretion, either accept and make payment upon such documents without responsibility for
further investigation, regardless of any notice or information to the contrary, or refuse to
accept and make payment upon such documents if such documents are not in strict compliance with
the terms of such Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly following its
receipt thereof, examine all documents purporting to represent a demand for payment under a
Letter of Credit. The Issuing Bank shall promptly give written notice to the Administrative
Agent and Borrower of such demand for payment and whether the Issuing Bank has made or will make
an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice
shall not relieve Borrower of its Reimbursement Obligation to the Issuing Bank and the Revolving
Lenders with respect to any such LC Disbursement (other than with respect to the timing of such
Reimbursement Obligation set forth in Section 2.18(e)).

          (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then,
unless Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is
made, the unpaid amount thereof shall bear interest payable on demand, for each day from and
including the date such LC Disbursement is made to but excluding the date that Borrower
reimburses such LC Disbursement, at the rate per annum determined pursuant to Section
2.06(c). Interest accrued pursuant to this paragraph shall be for the account of the
Issuing Bank, except that interest accrued on and after the date of payment by any Revolving
Lender pursuant to Section 2.18(e) to reimburse the Issuing Bank shall be for the
account of such Lender to the extent of such payment.

-60-

 

          (i) Cash Collateralization. If any Event of Default shall occur and be continuing,
on the Business Day that Borrower receives notice from the Administrative Agent or the Required
Revolving Lenders (or, if the maturity of the Loans has been accelerated, Revolving Lenders with
LC Exposure representing greater than 50% of the total LC Exposure) demanding the deposit of
cash collateral pursuant to this paragraph, Borrower shall deposit on terms and in accounts
satisfactory to the Collateral Agent, in the name of the Collateral Agent and for the benefit of
the Revolving Lenders, an amount in cash or Cash Equivalents equal to the LC Exposure as of such
date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such
cash collateral shall become effective immediately, and such deposit shall become immediately
due and payable, without demand or other notice of any kind, upon the occurrence of any Event of
Default with respect to Borrower described in Section 8.01(g) or (h). Funds so
deposited shall be applied by the Collateral Agent to reimburse the Issuing Bank for LC
Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be
held for the satisfaction of outstanding Reimbursement Obligations or, if the maturity of the
Loans has been accelerated (but subject to the consent of Revolving Lenders with LC Exposure
representing greater than 50% of the total LC Exposure), be applied to satisfy other Obligations
of Borrower under this Agreement. If Borrower is required to provide an amount of cash
collateral hereunder as a result of the occurrence of an Event of Default, such amount plus any
accrued interest or realized profits with respect to such amounts (to the extent not applied as
aforesaid) shall be returned to Borrower within three Business Days after all Events of Default
have been cured or waived.

          (j) Additional Issuing Banks. Borrower may, at any time and from time to time,
designate one or more additional Revolving Lenders to act as an issuing bank under the terms of
this Agreement, with the consent of the Administrative Agent (which consent shall not be
unreasonably withheld) and such Revolving Lender(s). Any Lender designated as an issuing bank
pursuant to this paragraph (j) shall be deemed (in addition to being a Revolving Lender) to be
the Issuing Bank with respect to Letters of Credit issued or to be issued by such Revolving
Lender, and all references herein and in the other Loan Documents to the term “Issuing Bank”
shall, with respect to such Letters of Credit, be deemed to refer to such Revolving Lender in
its capacity as Issuing Bank, as the context shall require.

          (k) Resignation or Removal of the Issuing Bank. The Issuing Bank may resign as
Issuing Bank hereunder at any time upon at least 30 days’ prior notice to the Lenders, the
Administrative Agent and Borrower. The Issuing Bank may be replaced at any time by written
agreement among Borrower, each Agent, the replaced Issuing Bank and the successor Issuing Bank.
The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank or
any such additional Issuing Bank. At the time any such resignation or replacement shall become
effective, Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing
Bank pursuant to Section 2.05(c). From and after the effective date of any such
resignation or replacement or addition, as applicable, (i) the successor or additional Issuing
Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with
respect to Letters of Credit to be issued by it thereafter and (ii) references herein to the
term “Issuing Bank” shall be deemed to refer to such successor or

-61-

 

such addition or to any previous Issuing Bank, or to such successor or such addition and
all previous Issuing Banks, as the context shall require. After the resignation or replacement
of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of an Issuing Bank under this Agreement with
respect to Letters of Credit issued by it prior to such resignation or replacement, but shall
not be required to issue additional Letters of Credit. If at any time there is more than one
Issuing Bank hereunder, Borrower may, in its discretion, select which Issuing Bank is to issue
any particular Letter of Credit.

          (l) Other. The Issuing Bank shall be under no obligation to issue any Letter of
Credit if

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

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

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

     SECTION 2.19 Increase in Commitments.

          (a) Borrower Request. Borrower may by 10 Business Days’ written notice to the
Administrative Agent request, on up to but no more than four separate occasions, the
establishment of one or more new Term Loan Commitments by an amount not in excess of $40.0
million in the aggregate and not less than $5.0 million individually. Each such notice shall
specify (i) the date (each, an “Increase Effective Date”) on which Borrower proposes that the
increased or new Commitments shall be effective, which shall be a date not less than 10 Business
Days after the date on which such notice is delivered to the Administrative Agent and (ii) the
identity of each Eligible Assignee to whom Borrower proposes any portion of such increased or
new Commitments be allocated and the amounts of such allocations; provided that any existing
Lender approached to provide all or a portion of the increased or

-62-

 

new Commitments may elect or decline, in its sole discretion, to provide such increased or
new Commitment.

          (b) Conditions. The increased or new Commitments shall become effective, as of
such Increase Effective Date; provided that:

          (i) each of the conditions set forth in Section 4.02 shall be satisfied;

          (ii) no Event of Default shall have occurred and be continuing or would result from the
borrowings to be made on the Increase Effective Date;

          (iii) as of the Test Period, after calculating Consolidated EBITDA, Indebtedness and
Consolidated Interest Expense on a Pro Forma Basis to give effect to the borrowings to be
made on the Increase Effective Date, the Projects, any Permitted Acquisition (including any
Permitted Acquisition financed on the Increase Effective Date) and Asset Sales consummated
at any time on or after the first day of the Test Period as if the Projects and each such
Permitted Acquisition had been effected on the first day of such period and as if each such
Asset Sale had been consummated on the first day of such period, the Reporting Entity shall
be in compliance with each of the covenants set forth in Section 6.10;

          (iv) Borrower shall deliver or cause to be delivered any legal opinions or other
documents reasonably requested by the Administrative Agent in connection with any such
transaction.

          (c) Terms of New Loans and Commitments. The terms and provisions of Loans made
pursuant to the new Commitments shall be as follows:

          (i) terms and provisions of Term Loans made pursuant to new Commitments shall be,
except as otherwise set forth herein or in the Increase Joinder, identical to the Term Loans
(it being understood that such Term Loans may be part of an existing tranche of Term Loans);

          (ii) the weighted average life to maturity of all new Term Loans shall be no shorter
than the weighted average life to maturity of the existing Term Loans;

          (iii) the maturity date of the new Term Loans shall not be earlier than the Final
Maturity Date;

          (iv) the Applicable Margins for the new Term Loans shall be determined by Borrower and
the applicable new Lenders; provided, however, that the Applicable Margins for the new Term
Loans shall not be greater than the Applicable Margins then payable with respect to the Term
Loans plus 50 basis points.

The increased or new Commitments shall be effected by a joinder agreement (the “Increase Joinder”)
executed by Borrower, the Administrative Agent and each Lender making such

-63-

 

increased or new Commitment, in form and substance satisfactory to each of them. The Increase
Joinder may, without the consent of any other Lenders, effect such amendments to this Agreement and
the other Loan Documents as may be necessary or appropriate, in the opinion of the Administrative
Agent, to effect the provisions of this Section 2.19.

          (d) Making of New Term Loans. On any Increase Effective Date on which new
Commitments for Term Loans are effective, subject to the satisfaction of the foregoing terms and
conditions, each Lender of such new Commitment shall make a Term Loan to Borrower in an amount
equal to its new Commitment.

          (e) Equal and Ratable Benefit. The Loans and Commitments established pursuant to
this paragraph shall constitute Loans and Commitments under, and shall be entitled to all the
benefits afforded by, this Agreement and the other Loan Documents, and shall, without limiting
the foregoing, benefit equally and ratably from the Guarantees and security interests created by
the Security Documents. The Loan Parties shall take any actions reasonably required by the
Administrative Agent to ensure and/or demonstrate that the Lien and security interests granted
by the Security Documents continue to be perfected under the UCC or otherwise after giving
effect to the establishment of any such Class of Term Loans or any such new Commitments.

     SECTION 2.20 Modification of Revolving Loan.

          (a) Borrower Request. Borrower may by 30 Business Days’ written notice to the
Administrative Agent elect to request, effective as of the Revolving Maturity Date, to extend
the Revolving Loans and the Revolving Loan Commitments beyond the Revolving Maturity Date or to
replace the Revolving Loan Commitments. Such notice shall specify (i) the date on which the
Borrower proposes that the extended or new Revolving Loan Commitments shall mature and (ii) the
identity of each Eligible Assignee to whom Borrower proposes any portion of such extended or new
Revolving Loan Commitments be allocated and the amounts of such allocations; provided that any
existing Lender approached to provide all or a portion of the extended or new Revolving Loan
Commitments may elect or decline, in its sole discretion, to provide such extended or new
Revolving Loan Commitment and if it so declines the unpaid principal amount of its Revolving
Loans shall be paid in full on the Revolving Maturity Date.

          (b) Conditions. The extended or new Revolving Loan Commitments shall become
effective, as of the Revolving Loan Maturity Date; provided that:

          (i) each of the conditions set forth in Section 4.02 shall be satisfied;

          (ii) no Event of Default shall have occurred and be continuing or would result from the
extension or replacement of the Revolving Loan Commitments; and

-64-

 

          (iii) Borrower shall deliver or cause to be delivered any legal opinions or other
documents reasonably requested by the Administrative Agent in connection with any such
transaction.

          (c) Terms of New Revolving Loans and Revolving Loan Commitments. The terms and
provisions of Revolving Loans and Revolving Loan Commitments made pursuant to such extension or
replacement shall be identical to those of the current Revolving Loans and Revolving Loan
Commitments. The extended or new Revolving Loan Commitments shall be effected by a joinder
agreement (the “Revolving Loan Joinder”) executed by Borrower, the Administrative Agent and each
Lender making such extended or new Commitment, in form and substance satisfactory to each of
them. The Revolving Loan Joinder may, without the consent of any other Lenders, effect such
amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in
the opinion of the Administrative Agent, to effect the provisions of this Section 2.20.

          (d) Equal and Ratable Benefit. The Loans and Commitments extended or established
pursuant to this paragraph shall constitute Loans and Commitments under, and shall be entitled
to all the benefits afforded by, this Agreement and the other Loan Documents, and shall, without
limiting the foregoing, benefit equally and ratably from the Guarantees and security interests
created by the Security Documents. The Loan Parties shall take any actions reasonably required
by the Administrative Agent to ensure and/or demonstrate that the Lien and security interests
granted by the Security Documents continue to be perfected under the UCC or otherwise after
giving effect to the extension or establishment of any such Loans or any such Commitments.

ARTICLE III

REPRESENTATIONS AND WARRANTIES

     Each Loan Party (notwithstanding anything in this Agreement to the contrary, Regency MLP shall
not be considered a “Loan Party” or a “Company” for purposes of any Section of this Article except
Sections 3.01, 3.02, 3.03, 3.10 and 3.11) represents and
warrants to the Administrative Agent, the Collateral Agent, the Issuing Bank and each of the
Lenders (with references to the Companies being references thereto after giving effect to the
Transactions to occur on the MLP Effectiveness Date unless otherwise expressly stated) that:

     SECTION 3.01 Organization; Powers. Each Company (a) is duly organized and validly existing
under the laws of the jurisdiction of its organization, (b) has all requisite organizational power
and authority to carry on its business as now conducted and to own and lease its property and (c)
is qualified and in good standing (to the extent such concept is applicable in the applicable
jurisdiction) to do business in every jurisdiction where such qualification is required, except in
such jurisdictions where the failure to so qualify or be in good standing, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse Effect. There is no
existing default under any Organizational Document of any Company or any event which, with the
giving of notice or passage of time or both, would constitute a default by any party thereunder.

-65-

 

     SECTION 3.02 Authorization; Enforceability. The Transactions to be entered into by each
Loan Party are within such Loan Party’s powers and have been duly authorized by all necessary
action on the part of such Loan Party. This Agreement has been duly executed and delivered by each
Loan Party and constitutes, and each other Loan Document to which any Loan Party is to be a party,
when executed and delivered by such Loan Party, will constitute, a legal, valid and binding
obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights
generally and subject to general principles of equity, regardless of whether considered in a
proceeding in equity or at law.

     SECTION 3.03 No Conflicts. Except as set forth on Schedule 3.03, the Transactions
(a) do not require any consent or approval of, registration or filing with, or any other action by,
any Governmental Authority, except (i) such as have been obtained or made and are in full force and
effect, (ii) filings necessary to perfect Liens created by the Loan Documents and (iii) consents,
approvals, registrations, filings, permits or actions the failure to obtain or perform which could
not reasonably be expected to result in a Material Adverse Effect, (b) will not violate the
Organizational Documents of any Company, (c) will not violate any Requirement of Law in any
material respect, (d) will not violate or result in a default or require any consent or approval
under any indenture, agreement or other instrument binding upon any Company or its property, or
give rise to a right thereunder to require any payment to be made by any Company, except for
violations, defaults or the creation of such rights that could not reasonably be expected to result
in a Material Adverse Effect, and (e) will not result in the creation or imposition of any Lien on
any property of any Company, except Liens created by the Loan Documents and Permitted Liens.

     SECTION 3.04 Financial Statements; Projections.

          (a) Historical Financial Statements. Borrower has heretofore delivered to the
Lenders the consolidated balance sheets and related income statements and statements of cash
flows and statements of changes in member interests of Borrower (i) as of and for the fiscal
year ended December 31, 2004, audited by and accompanied by the unqualified opinion of Deloitte
& Touche LLP, independent public accountants, and (ii) as of and for the three-month and
six-month periods ended June 30, 2005 and as of and for the three-month and six-month periods
ended June 30, 2004, in the case of clauses (i) and (ii), certified by the chief financial
officer of Borrower. Such financial statements and all financial statements delivered pursuant
to Sections 5.01(a) and (b) have been prepared in accordance with GAAP and
fairly present, in all material respects, the consolidated financial condition and results of
operations and cash flows of Borrower and its Subsidiaries as of the dates and for the periods
to which they relate.

          (b) No Liabilities. Except as set forth in the financial statements referred to in
Section 3.04(a), there are no liabilities of any Company of any kind, whether accrued,
contingent, absolute, determined, determinable or otherwise, which could reasonably be expected
to result in a Material Adverse Effect. Since June 30, 2005 there has been no event,

-66-

 

change, circumstance or occurrence that, individually or in the aggregate, has had or could
reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.05 Properties.

          (a) Generally. Each Company has good title to, or valid leasehold interests in,
all its property material to its business, free and clear of all Liens except for, in the case
of Collateral, Permitted Collateral Liens and, in the case of all other material property,
Permitted Liens and minor irregularities or deficiencies in title that, individually or in the
aggregate, do not materially interfere with its ability to conduct its business as currently
conducted or to utilize such property for its intended purpose. The property of the Companies,
taken as a whole, is in good operating order, condition and repair (ordinary wear and tear
excepted) in accordance with industry standards.

          (b) Real Property. Schedules 8(a) and 8(b) to the Perfection Certificate dated the
MLP Effectiveness Date contain a true and complete list of each interest in Real Property (i)
owned by any Company as of the date hereof and describes the type of interest therein held by
such Company and whether such owned Real Property is leased and if leased whether the underlying
Lease contains any option to purchase all or any portion of such Real Property or any interest
therein or contains any right of first refusal relating to any sale of such Real Property or any
portion thereof or interest therein and (ii) leased, subleased or otherwise occupied or utilized
by any Company, as lessee, sublessee, franchisee or licensee, as of the date hereof and
describes the type of interest therein held by such Company and, in each of the cases described
in clauses (i) and (ii) of this Section 3.05(b), whether any Lease requires the consent
of the landlord or tenant thereunder, or other party thereto, to the Transactions. As of the
MLP Effectiveness Date, with respect to each Real Property or Mortgaged Property, there are no
Leases in which Borrower or any Subsidiary holds the lessor’s interest.

          (c) Collateral. Each Company owns or has rights to use all of the Collateral and
all rights with respect to any of the foregoing used in, necessary for or material to each
Company’s business as currently conducted. The use by each Company of such Collateral and all
such rights with respect to the foregoing do not infringe on the rights of any person other than
such infringement which could not, individually or in the aggregate, reasonably be expected to
result in a Material Adverse Effect. No claim has been made and remains outstanding that any
Company’s use of any Collateral does or may violate the rights of any third party that could,
individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.06 Intellectual Property.

          (a) Ownership/No Claims. Each Loan Party owns, or is licensed to use, all patents,
patent applications, trademarks, trade names, servicemarks, copyrights, technology, trade
secrets, proprietary information, domain names, know-how and processes necessary for the conduct
of its business as currently conducted (the “Intellectual Property”), except for those the
failure to own or license which, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. No claim has been asserted

-67-

 

and is pending by any person challenging or questioning the use of any such Intellectual
Property or the validity or effectiveness of any such Intellectual Property, nor does any Loan
Party know of any valid basis for any such claim, in each case that could reasonably be expected
to result in a Material Adverse Effect. The use of such Intellectual Property by each Loan
Party does not infringe the rights of any person, except for such claims and infringements that,
individually or in the aggregate, could not reasonably be expected to result in a Material
Adverse Effect.

          (b) Registrations. Except pursuant to licenses and other user agreements entered
into by each Loan Party in the ordinary course of business that are listed in Schedule 12(a) or
12(b) to the Perfection Certificate, on and as of the date hereof (i) each Loan Party owns and
possesses the right to use, and has done nothing to authorize or enable any other person to use,
any copyright, patent or trademark (as such terms are defined in the Security Agreement) listed
in Schedule 12(a) or 12(b) to the Perfection Certificate and (ii) all registrations listed in
Schedule 12(a) or 12(b) to the Perfection Certificate are valid and in full force and effect.

          (c) No Violations or Proceedings. To each Loan Party’s knowledge, on and as of the
date hereof, there is no material violation by others of any right of such Loan Party with
respect to any copyright, patent or trademark listed in Schedule 12(a) or 12(b) to the
Perfection Certificate, pledged by it under the name of such Loan Party except as may be set
forth on Schedule 3.06(c).

     SECTION 3.07 Equity Interests and Subsidiaries.

          (a) Equity Interests. Schedules 1(a) and 10(a) to the Perfection Certificate dated
the MLP Effectiveness Date set forth a list of (i) all the Subsidiaries of Borrower and their
jurisdictions of organization as of the MLP Effectiveness Date and (ii) the number of each class
of its Equity Interests authorized, and the number outstanding, on the MLP Effectiveness Date
and the number of shares covered by all outstanding options, warrants, rights of conversion or
purchase and similar rights at the MLP Effectiveness Date. All Equity Interests of each Company
are duly and validly issued and are fully paid and non-assessable, and, other than the Equity
Interests of Borrower, are owned by Borrower, directly or indirectly through Wholly Owned
Subsidiaries. All Equity Interests of Borrower are owned directly or indirectly by Regency MLP.
Each Loan Party is the record and beneficial owner of, and has good and defensible title to,
the Equity Interests pledged by it under the Security Agreement, free of any and all Liens,
rights or claims of other persons, except the security interest created by the Security
Agreement, and there are no outstanding warrants, options or other rights to purchase, or
shareholder, voting trust or similar agreements outstanding with respect to, or property that is
convertible into, or that requires the issuance or sale of, any such Equity Interests. All
Subsidiaries of Borrower existing on the MLP Effectiveness Date are Guarantors.

          (b) No Consent of Third Parties Required. No consent of any person including any
other general or limited partner, any other member of a limited liability company, any other
shareholder or any other trust beneficiary is necessary or reasonably

-68-

 

desirable (from the perspective of a secured party) in connection with the creation,
perfection or First Priority status of the security interest of the Collateral Agent in any
Equity Interests pledged to the Collateral Agent for the benefit of the Secured Parties under
the Security Agreement or the exercise by the Collateral Agent of the voting or other rights
provided for in the Security Agreement or the exercise of remedies in respect thereof.

          (c) Organizational Chart. An accurate organizational chart, showing the ownership
structure of Regency MLP, Borrower and each of its Subsidiaries on the MLP Effectiveness Date,
and after giving effect to the Transactions, is set forth on Schedule 10(a) to the Perfection
Certificate dated the MLP Effectiveness Date.

          (d) Guarantors/Collateral. As of the MLP Effectiveness Date all Loan Parties have
complied with Section 5.11 of the Existing Credit Agreement as in effect on the MLP
Effectiveness Date without giving effect to any grace periods set forth therein.

     SECTION 3.08 Litigation; Compliance with Laws. There are no actions, suits or proceedings
at law or in equity by or before any Governmental Authority now pending or, to the knowledge of any
Company, threatened against or affecting any Company or any business, property or rights of any
Company (a) that involve any Loan Document, the Previous Transactions or the Transactions or (b)
which could reasonably be expected, individually or in the aggregate, to result in a Material
Adverse Effect. Except for matters covered by Section 3.18, no Company or any of its
property is in violation of, nor will the continued operation of its property as currently
conducted violate, any Requirements of Law (including any zoning or building ordinance, code or
approval or any building permits) or any restrictions of record or agreements affecting any
Company’s Real Property or is in default with respect to any Requirement of Law, where such
violation or default, individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Effect.

     SECTION 3.09 Agreements. No Company is a party to any agreement or instrument or subject
to any corporate or other constitutional restriction that has resulted or could reasonably be
expected to result in a Material Adverse Effect. No Company is in default in any manner under any
provision of any indenture or other agreement or instrument evidencing Indebtedness, or any other
agreement or instrument to which it is a party or by which it or any of its property is or may be
bound, where such default could reasonably be expected to result in a Material Adverse Effect, and
no condition exists which, with the giving of notice or the lapse of time or both, would constitute
such a default. Complete and correct copies of all agreements to which any Company is a party as
in effect on the date hereof and that are required to be filed as exhibits to the Registration
Statement have been so filed and all such agreements are in full force and effect as of the date
hereof.

     SECTION 3.10 Federal Reserve Regulations. No Company is engaged principally, or as one of
its important activities, in the business of extending credit for the purpose of buying or carrying
Margin Stock. No part of the proceeds of any Loan or any Letter of Credit will be used, whether
directly or indirectly, and whether immediately, incidentally or ultimately, for any purpose that
entails a violation of, or that is inconsistent with, the provisions of the regulations of

-69-

 

the Board, including Regulation T, U or X. The pledge of the Securities Collateral pursuant to the
Security Agreement does not violate such regulations.

     SECTION 3.11 Investment Company Act; Public Utility Holding Company Act. No Company is (a)
an “investment company” or a company “controlled” by an “investment company,” as defined in, or
subject to regulation under, the Investment Company Act of 1940, as amended, or (b) a “holding
company,” an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company,”
as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935, as
amended, other than in compliance with Section 9(a)(2) thereof. No approval, consent or notice
pursuant to the Public Utility Holding Company Act of 1935, as amended, is required in connection
with the Transactions or is required in connection with making any extensions of credit hereunder.

     SECTION 3.12 Use of Proceeds. Borrower will use the proceeds of the Revolving Loans
funded after the MLP Effectiveness Date, and the Swingline Loans funded after the MLP Effectiveness
Date for working capital and general corporate purposes (including to effect Permitted Acquisitions
and the Projects).

     SECTION 3.13 Taxes. Each Company has (a) timely filed or caused to be timely filed all
federal Tax Returns and all material state, local and foreign Tax Returns or materials required to
have been filed by it and (b) duly and timely paid, collected or remitted or caused to be duly and
timely paid, collected or remitted all Taxes (whether or not shown on any Tax Return) due and
payable, collectible or remittable by it and all assessments received by it, except Taxes (i) that
are being contested in good faith by appropriate proceedings and for which such Company has set
aside on its books adequate reserves in accordance with GAAP and (ii) which could not, individually
or in the aggregate, have a Material Adverse Effect. Each Company has made adequate provision in
accordance with GAAP for all Taxes not yet due and payable. Each Company is unaware of any
proposed or pending tax assessments, deficiencies or audits that could be reasonably expected to,
individually or in the aggregate, result in a Material Adverse Effect.

     SECTION 3.14 No Material Misstatements. No written information, report, financial
statement, certificate, Borrowing Request, LC Request, exhibit or schedule furnished by or on
behalf of any Company to the Administrative Agent or any Lender in connection with the negotiation
of any Loan Document or included therein or delivered pursuant thereto, taken as a whole, or the
Registration Statement contained or contains any material misstatement of fact or omitted or omits
to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were or are made, not misleading as of the date such information is
dated or certified; provided that (a) to the extent any such information, report, financial
statement, exhibit or schedule was based upon or constitutes a forecast or projection, each Company
represents only that it acted in good faith and utilized reasonable assumptions and due care in the
preparation of such information, report, financial statement, exhibit or schedule (it being
recognized by the Lenders, however, that projections as to future events are not to be viewed as
facts and that results during the period(s) covered by such projections may differ from the
projected results and that such differences may be material and that the Loan Parties make no

-70-

 

representation that such projections will be realized) and (b) as to statements, information and
reports supplied by third parties after the MLP Effectiveness Date, Borrower represents only that
it is not aware of any material misstatement or omission therein.

     SECTION 3.15 Labor Matters. As of the Second Amendment Effectiveness Date, there are no
strikes, lockouts or slowdowns against any Company pending or, to the knowledge of any Company,
threatened. The hours worked by and payments made to employees of any Company have not been in
violation of the Fair Labor Standards Act of 1938, as amended, or any other applicable federal,
state, local or foreign law dealing with such matters in any manner which could reasonably be
expected to result in a Material Adverse Effect. All payments due from any Company, or for which
any claim may be made against any Company, on account of wages and employee health and welfare
insurance and other benefits, have been paid or accrued as a liability on the books of such Company
except where the failure to do so could not reasonably be expected to result in a Material Adverse
Effect. The consummation of the Transactions will not give rise to any right of termination or
right of renegotiation on the part of any union under any collective bargaining agreement to which
any Company is bound.

     SECTION 3.16 Solvency. Immediately after the consummation of the Transactions to occur on
the MLP Effectiveness Date and immediately following the making of each Loan and after giving
effect to the application of the proceeds of each Loan, (a) the fair value of the properties of
each Loan Party (individually and on a consolidated basis with its Subsidiaries, and determined on
a going concern basis) will exceed the probable liability of its debts and other liabilities,
subordinated, contingent or otherwise; (b) the present fair saleable value of the property of each
Loan Party (individually and on a consolidated basis with its Subsidiaries) will be greater than
the amount that will be required to pay the probable liability of its debts and other liabilities,
subordinated, contingent or otherwise, as such debts and other liabilities become absolute and
matured; (c) each Loan Party (individually and on a consolidated basis with its Subsidiaries) will
be able to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured; and (d) each Loan Party (individually and on a
consolidated basis with its Subsidiaries) will not have unreasonably small capital with which to
conduct its business in which it is engaged as such business is now conducted and is proposed to be
conducted following the MLP Effectiveness Date.

     SECTION 3.17 Employee Benefit Plans. Each Company and its ERISA Affiliates is in
compliance in all material respects with the applicable provisions of ERISA and the Code and the
regulations and published interpretations thereunder. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events, could reasonably be
expected to result in material liability of any Company or any of its ERISA Affiliates or the
imposition of a Lien on any of the property of any Company. The present value of all accumulated
benefit obligations of all underfunded Plans (based on the assumptions used for purposes of
Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent
financial statements reflecting such amounts, exceed by more than $250,000 the fair market value of
the property of all such underfunded Plans. Using actuarial assumptions and computation methods
consistent with subpart I of subtitle E of Title IV of ERISA, the aggregate liabilities of each
Company or its ERISA Affiliates to all Multiemployer Plans in the event of a

-71-

 

complete withdrawal therefrom, as of the close of the most recent fiscal year of each such
Multiemployer Plan, could not reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.18 Environmental Matters.

          (a) Except as set forth in Schedule 3.18 and except as, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse Effect:

          (i) The Companies and their businesses, operations and Real Property are in compliance
with, and the Companies have no liability under, Environmental Law;

          (ii) The Companies have obtained all Environmental Permits required for the conduct of
their businesses and operations, and the ownership, operation and use of their property,
under Environmental Law, all such Environmental Permits are valid and in good standing;

          (iii) There has been no Release or threatened Release of Hazardous Material on, at,
under or from any Real Property or facility presently or formerly owned, leased or operated
by the Companies or their predecessors in interest that could result in liability by the
Companies under Environmental Law;

          (iv) There is no Environmental Claim pending or, to the knowledge of the Companies,
threatened against the Companies, or relating to the Real Property currently or formerly
owned, leased or operated by the Companies or relating to the operations of the Companies,
and there are no actions, activities, circumstances, conditions, events or incidents that
could form the basis of such an Environmental Claim;

          (v) No Real Property or facility owned, operated or leased by the Companies and, to the
knowledge of the Companies, no Real Property or facility formerly owned, operated or leased
by the Companies or any of their predecessors in interest is (A) listed or proposed for
listing on the National Priorities List promulgated pursuant to CERCLA or (B) listed on the
Comprehensive Environmental Response, Compensation and Liability Information System
promulgated pursuant to CERCLA or (C) included on any similar list maintained by any
Governmental Authority including any such list relating to petroleum;

          (vi) No material Lien has been recorded or, to the knowledge of any Company, threatened
under any Environmental Law with respect to any Real Property or other assets of the
Companies;

          (vii) The execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby will not require any notification, registration,
filing, reporting, disclosure, investigation, remediation or cleanup pursuant to any
Governmental Real Property Disclosure Requirements or any other Environmental Law; and

-72-

 

          (viii) The Companies have made available to the Lenders all material records and files
in the possession, custody or control of, or otherwise reasonably available to, the
Companies concerning compliance with or liability under Environmental Law, including those
concerning the existence of Hazardous Material at Real Property or facilities currently or
formerly owned, operated, leased or used by the Companies.

     SECTION 3.19 Insurance. Schedule 3.19 sets forth a true, complete and correct
description of all insurance maintained by each Loan Party as of the MLP Effectiveness Date. All
material insurance maintained by the Companies is in full force and effect. Each Company has
insurance in such amounts and covering such risks and liabilities as are customary for companies of
a similar size engaged in similar businesses in similar locations.

     SECTION 3.20 Security Documents.

          (a) Security Agreement. The Security Agreement is effective to create in favor of
the Collateral Agent for the benefit of the Secured Parties, legal, valid and enforceable Liens
on, and security interests in, the Security Agreement Collateral and, (i) when financing
statements and other filings in appropriate form are filed in the offices specified on Schedule
7 to the Perfection Certificate and (ii) upon the taking of possession or control by the
Collateral Agent of the Security Agreement Collateral with respect to which a security interest
may be perfected only by possession or control (which possession or control shall be given to
the Collateral Agent to the extent possession or control by the Collateral Agent is required by
each Security Agreement), the Liens created by the Security Agreement shall constitute fully
perfected First Priority Liens on, and security interests in, all right, title and interest of

relevant time in the relevant jurisdiction), in each case subject to no Liens other than
Permitted Collateral Liens.

          (b) Copyright Office Filing. When the Security Agreement or a short form thereof

title and interest of the grantors thereunder in the Registered Copyrights and Registered
Copyright Licenses (each as defined in such Security Agreement), in each case subject to no
Liens other than Permitted Collateral Liens.

          (c) Mortgages. Each Mortgage is effective to create, in favor of the Collateral
Agent, for its benefit and the benefit of the Secured Parties, legal, valid and enforceable
First Priority Liens on, and security interests in, all of the Loan Parties’ right, title and
interest in and to the Mortgaged Properties thereunder and the proceeds thereof, subject only to
Permitted Collateral Liens or other Liens acceptable to the Collateral Agent, and when the
Mortgages are filed in the offices specified on Schedule 8(a) to the Perfection Certificate
dated the MLP Effectiveness Date (or, in the case of any Mortgage executed and delivered after
the date thereof in accordance with the provisions of Sections 5.11 and 5.12,
when such Mortgage is filed in the offices specified in the local counsel opinion delivered with
respect thereto in accordance with the provisions of Sections 5.11 and 5.12),
the Mortgages shall

-73-

 

constitute First Priority fully perfected Liens on, and security interests in, all right,
title and interest of the Loan Parties in the Mortgaged Properties and the proceeds thereof, in
each case prior and superior in right to any other person, other than Liens permitted by such
Mortgage.

          (d) Valid Liens. Each Security Document delivered pursuant to Sections
5.11 and 5.12 will, upon execution and delivery thereof, be effective to create in
favor of the Collateral Agent, for the benefit of the Secured Parties, legal, valid and

interest in and to the Collateral thereunder, and when all appropriate filings or recordings are

none of its Affiliates is in violation of any Requirement of Law relating to terrorism or money

Secured Obligations (unless the subject property is already mortgaged to a third party to the
extent permitted by Section 6.02). Such Mortgages shall be granted pursuant to
documentation reasonably satisfactory in form and substance to the Administrative Agent and the
Collateral Agent and shall constitute valid and enforceable

-83-

enforceable perfected First Priority Liens subject only to Permitted Collateral Liens or other
Liens acceptable to the Collateral Agent. The Mortgages or instruments related thereto shall be
duly recorded or filed in such manner and in such places as are required by law to establish,
perfect, preserve and protect the Liens in favor of the Collateral Agent required to be granted
pursuant to the Mortgages and all taxes, fees and other charges payable in connection therewith

Documents or otherwise deemed by the Administrative Agent or the Collateral Agent reasonably
necessary or desirable for the continued validity, perfection and priority of the Liens on the
Collateral covered thereby subject to no other Liens except as permitted by the applicable Security
Document, or obtain any consents or waivers as may be necessary or appropriate in connection
therewith. Deliver or cause to be delivered to the Administrative Agent and the Collateral Agent
from time to time such other documentation, consents, authorizations, approvals and orders in form
and substance reasonably satisfactory to the Administrative Agent and the Collateral Agent as the
Administrative Agent and the Collateral Agent shall reasonably deem necessary to perfect or
maintain the Liens on the Collateral pursuant to the Security Documents. Upon the exercise by the
Administrative Agent, the Collateral Agent or any Lender of any power, right, privilege or remedy
pursuant to any Loan Document which requires any consent, approval, registration, qualification or
authorization of any Governmental Authority, execute and deliver all applications, certifications,
instruments and other documents and papers that the Administrative Agent, the Collateral Agent or
such Lender may require. If the Administrative Agent, the Collateral Agent or the Required Lenders
determine that they are required by a Requirement of Law to have appraisals prepared in respect of
the Real Property of any Loan Party constituting Collateral, Borrower shall provide to the
Administrative Agent appraisals that satisfy the applicable requirements of the Real Estate

or the Administrative Agent may reasonably request and (B) it shall have taken all action
reasonably satisfactory to the Collateral Agent to maintain the perfection and priority of the
security interest of the Collateral Agent for the benefit of the Secured Parties in the
Collateral, if applicable; provided, however, that if such Loan Party does not have, and has not
had, assets or liabilities in excess of $25,000, such notice may be provided promptly (but in no
event later than 15 days) after effecting the changes described above. Each Loan Party agrees
to promptly provide the Collateral Agent with certified Organizational Documents reflecting any
of the changes described in the preceding sentence. Each Loan Party also agrees to promptly
notify the Collateral Agent of any change in the location of any office in which it maintains

Guarantors hereunder which shall remain absolute, irrevocable and unconditional under any and all
circumstances as described above:

          (i) at any time or from time to time, without notice to the Guarantors, the time for
any performance of or compliance with any of the Guaranteed Obligations shall be extended,
or such performance or compliance shall be waived;

          (ii) any of the acts mentioned in any of the provisions of this Agreement or the Notes,
if any, or any other agreement or instrument referred to herein or therein shall be done or
omitted;

          (iii) the maturity of any of the Guaranteed Obligations shall be accelerated, or any of
the Guaranteed Obligations shall be amended in any respect, or any right under the Loan
Documents or any other agreement or instrument referred to herein or therein shall be
amended or waived in any respect or any other guarantee of any of the Guaranteed Obligations
or any security therefor shall be released or exchanged in whole or in part or otherwise
dealt with;

          (iv) any Lien or security interest granted to, or in favor of, Issuing Bank or any
Lender or Agent as security for any of the Guaranteed Obligations shall fail to be
perfected; or

          (v) the release of any other Guarantor pursuant to Section 7.09.

          The Guarantors hereby expressly waive diligence, presentment, demand of payment, protest and
all notices whatsoever, and any requirement that any Secured Party exhaust any right, power or
remedy or proceed against Borrower under this Agreement or the Notes, if any, or any other
agreement or instrument referred to herein or therein, or against any other person under any other
guarantee of, or security for, any of the Guaranteed Obligations. The Guarantors waive any and all
notice of the creation, renewal, extension, waiver, termination or

-101-

 

accrual of any of the Guaranteed Obligations and notice of or proof of reliance by any Secured
Party upon this Guarantee or acceptance of this Guarantee, and the Guaranteed Obligations, and any
of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon
this Guarantee, and all dealings between Borrower and the Secured Parties shall likewise be
conclusively presumed to have been had or consummated in reliance upon this Guarantee. This
Guarantee shall be construed as a continuing, absolute, irrevocable and unconditional guarantee of
payment without regard to any right of offset with respect to the Guaranteed Obligations at any
time or from time to time held by Secured Parties, and the obligations and liabilities of the
Guarantors hereunder shall not be conditioned or contingent upon the pursuit by the Secured Parties
or any other person at any time of any right or remedy against Borrower or against any other person
which may be or become liable in respect of all or any part of the Guaranteed Obligations or
against any collateral security or guarantee therefor or right of offset with respect thereto.
This Guarantee shall remain in full force and effect and be binding in accordance with and to the
extent of its terms upon the Guarantors and the successors and assigns thereof, and shall inure to
the benefit of the Lenders, and their respective successors and assigns, notwithstanding that from
time to time during the term of this Agreement there may be no Guaranteed Obligations outstanding.

     SECTION 7.03 Reinstatement. The obligations of the Guarantors under this Article VII shall
be automatically reinstated if and to the extent that for any reason any payment by or on behalf of
Borrower or other Loan Party in respect of the Guaranteed Obligations is rescinded or must be
otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any
proceedings in bankruptcy or reorganization or otherwise.

     SECTION 7.04 Subrogation; Subordination. Each Guarantor hereby agrees that until the
indefeasible payment and satisfaction in full in cash of all Guaranteed Obligations and the
expiration and termination of the Commitments of the Lenders under this Agreement it shall waive
any claim and shall not exercise any right or remedy, direct or indirect, arising by reason of any
performance by it of its guarantee in Section 7.01, whether by subrogation or otherwise, against
Borrower or any other Guarantor of any of the Guaranteed Obligations or any security for any of the
Guaranteed Obligations. Any Indebtedness of any Loan Party permitted pursuant to Section 6.01(d)
shall be subordinated to such Loan Party’s Secured Obligations in the manner set forth in the
Intercompany Note evidencing such Indebtedness.

     SECTION 7.05 Remedies. The Guarantors jointly and severally agree that, as between the
Guarantors and the Lenders, the obligations of Borrower under this Agreement and the Notes, if any,
may be declared to be forthwith due and payable as provided in Section 8.01 (and shall be deemed to
have become automatically due and payable in the circumstances provided in Section 8.01) for
purposes of Section 7.01, notwithstanding any stay, injunction or other prohibition preventing such
declaration (or such obligations from becoming automatically due and payable) as against Borrower
and that, in the event of such declaration (or such obligations being deemed to have become
automatically due and payable), such obligations (whether or not due and payable by Borrower) shall
forthwith become due and payable by the Guarantors for purposes of Section 7.01.

-102-

 

     SECTION 7.06 Instrument for the Payment of Money. Each Guarantor hereby acknowledges that
the guarantee in this Article VII constitutes an instrument for the payment of money, and consents
and agrees that any Lender or Agent, at its sole option, in the event of a dispute by such
Guarantor in the payment of any moneys due hereunder, shall have the right to bring a motion-action
under New York CPLR Section 3213.

     SECTION 7.07 Continuing Guarantee. The guarantee in this Article VII is a continuing
guarantee of payment, and shall apply to all Guaranteed Obligations whenever arising.

     SECTION 7.08 General Limitation on Guarantee Obligations. In any action or proceeding
involving any state corporate limited partnership or limited liability company law, or any
applicable state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting
the rights of creditors generally, if the obligations of any Guarantor under Section 7.01 would
otherwise be held or determined to be void, voidable, invalid or unenforceable, or subordinated to
the claims of any other creditors, on account of the amount of its liability under Section 7.01,
then, notwithstanding any other provision to the contrary, the amount of such liability shall,
without any further action by such Guarantor, any Loan Party or any other person, be automatically
limited and reduced to the highest amount that is valid and enforceable and not subordinated to the
claims of other creditors as determined in such action or proceeding.

     SECTION 7.09 Release of Guarantors. If, in compliance with the terms and provisions of the
Loan Documents, all or substantially all of the Equity Interests or property of any Guarantor are
sold or otherwise transferred (a “Transferred Guarantor”) to a person or persons, none of which is
Borrower or a Subsidiary, such Transferred Guarantor shall, upon the consummation of such sale or
transfer, be released from its obligations under this Agreement (including under Section 10.03
hereof) and its obligations to pledge and grant any Collateral owned by it pursuant to any Security
Document and, in the case of a sale of all or substantially all of the Equity Interests of the
Transferred Guarantor, the pledge of such Equity Interests to the Collateral Agent pursuant to the
Security Agreements shall be released, and the Collateral Agent shall take such actions as are
necessary to effect each release described in this Section 7.09 in accordance with the relevant
provisions of the Security Documents.

ARTICLE VIII

Event of Default pursuant to this paragraph (f) unless the aggregate amount of all such
Indebtedness referred to in clauses (i) and (ii) exceeds $10.0 million at any one time (provided
that, in the case of Hedging Obligations, the amount counted for this purpose shall be the
amount payable by all Companies if such Hedging Obligations were terminated at such time);

          (g) an involuntary proceeding shall be commenced or an involuntary petition shall be filed
in a court of competent jurisdiction seeking (i) relief in respect of any Company, or of a

now constituted or hereafter amended, or any other federal, state or foreign bankruptcy,

          (i) one or more judgments, orders or decrees for the payment of money in an aggregate
amount in excess of $10.0 million (that are not covered by insurance from an insurance company
with an A.M. Best financial strength rating of at least A-, it being understood that even if
such amounts are covered by insurance from such an insurance company such amounts shall count
against such basket if responsibility for such amounts has been denied by such insurance
company) shall be rendered against any Company or any combination thereof and the same shall
remain undischarged, unvacated or unbonded for a period of 30 consecutive days during which
execution shall not be effectively stayed, or any action shall be legally taken by a judgment
creditor to levy upon properties of any Company to enforce any such judgment;

          (j) one or more ERISA Events shall have occurred that, in the opinion of the Required
Lenders, when taken together with all other such ERISA Events, could reasonably be expected to
result in a Material Adverse Effect;

          (k) any security interest and Lien purported to be created by any Security Document with
respect to any Collateral worth, individually or in the aggregate, in excess of $1.0 million
shall cease to be in full force and effect, or shall cease to give the Collateral Agent, for the
benefit of the Secured Parties, the Liens, rights, powers and privileges purported to be created
and granted under such Security Document (including a perfected First Priority security interest
in and Lien on all of such Collateral (except as otherwise expressly provided in this Agreement
or such Security Document)) in favor of the Collateral Agent, or shall be asserted by Borrower
or any other Loan Party not to be a valid, perfected, First Priority (except as otherwise
expressly provided in this Agreement or such Security Document) security interest in or Lien on
such Collateral;

          (l) any Loan Document or any material provisions thereof shall at any time and for any
reason be declared by a court of competent jurisdiction to be null and void, or a proceeding
shall be commenced by any Loan Party or any other person, or by any Governmental Authority,
seeking to establish the invalidity or unenforceability thereof (exclusive of questions of
interpretation of any provision thereof), or any Loan Party shall repudiate or deny any portion
of its liability or obligation for the Obligations; or

          (m) there shall have occurred a Change in Control;

-105-

 

then, and in every such event (other than an event with respect to Regency MLP or Borrower
described in paragraph (g) or (h) above), and at any time thereafter during the continuance of such
event, the Administrative Agent may, and at the request of the Required Lenders shall, by notice to
Borrower, take either or both of the following actions, at the same or different times: (i)
terminate forthwith the Commitments and (ii) declare the Loans and Reimbursement Obligations then
outstanding to be forthwith due and payable in whole or in part, whereupon the principal of the
Loans and Reimbursement Obligations so declared to be due and payable, together with accrued
interest thereon and any unpaid accrued Fees and all other Obligations of Borrower accrued
hereunder and under any other Loan Document, shall become forthwith due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are hereby expressly
waived by Borrower and the Guarantors, anything contained herein or in any other Loan Document to
the contrary notwithstanding; and in any event, with respect to Regency MLP or Borrower described
in paragraph (g) or (h) above, the Commitments shall automatically terminate and the principal of
the Loans and Reimbursement Obligations then outstanding, together with accrued interest thereon
and any unpaid accrued Fees and all other Obligations of Borrower accrued hereunder and under any
other Loan Document, shall automatically become due and payable, without presentment, demand,
protest or any other notice of any kind, all of which are hereby expressly waived by Borrower and
the Guarantors, anything contained herein or in any other Loan Document to the contrary
notwithstanding.

     SECTION 8.02 Rescission. If at any time after termination of the Commitments or
acceleration of the maturity of the Loans, Borrower shall pay all arrears of interest and all
payments on account of principal of the Loans and Reimbursement Obligations owing by it that shall
have become due otherwise than by acceleration (with interest on principal and, to the extent
permitted by law, on overdue interest, at the rates specified herein) and all Defaults (other than
non-payment of principal of and accrued interest on the Loans due and payable solely by virtue of
acceleration) shall be remedied or waived pursuant Section 10.02, then upon the written consent of
the Required Lenders and written notice to Borrower, the termination of the Commitments or the
acceleration and their consequences may be rescinded and annulled; but such action shall not affect
any subsequent Default or impair any right or remedy consequent thereon. The provisions of the
preceding sentence are intended merely to bind the Lenders and the Issuing Bank to a decision that
may be made at the election of the Required Lenders, and such provisions are not intended to
benefit Borrower and do not give Borrower the right to require the Lenders to rescind or annul any
acceleration hereunder, even if the conditions set forth herein are met.

     SECTION 8.03 Application of Proceeds. The proceeds received by the Collateral Agent in
respect of any sale of, collection from or other realization upon all or any part of the Collateral
pursuant to the exercise by the Collateral Agent of its remedies shall be applied, in full or in
part, together with any other sums then held by the Collateral Agent pursuant to this Agreement,
promptly by the Collateral Agent as follows:

          
(a) First, to the payment of all reasonable costs and expenses, fees, commissions and taxes
of such sale, collection or other realization including compensation to the Collateral Agent and
its agents and counsel, and all expenses, liabilities and advances

-106-

 

made or incurred by the Collateral Agent in connection therewith and all amounts for which
the Collateral Agent is entitled to indemnification pursuant to the provisions of any Loan
Document, together with interest on each such amount at the highest rate then in effect under
this Agreement from and after the date such amount is due, owing or unpaid until paid in full;

          (b) Second, to the payment of all other reasonable costs and expenses of such sale,
collection or other realization including compensation to the other Secured Parties and their
agents and counsel and all costs, liabilities and advances made or incurred by the other Secured
Parties in connection therewith, together with interest on each such amount at the highest rate
then in effect under this Agreement from and after the date such amount is due, owing or unpaid
until paid in full;

          (c) Third, without duplication of amounts applied pursuant to clauses (a) and (b) above, to
the indefeasible payment in full in cash, pro rata, of interest and other amounts constituting
Obligations (other than principal and Reimbursement Obligations) and any fees, premiums and
scheduled periodic payments due under Hedging Agreements constituting Secured Obligations and
any interest accrued thereon, in each case equally and ratably in accordance with the respective
amounts thereof then due and owing;

          (d) Fourth, to the indefeasible payment in full in cash, pro rata, of principal amount of
the Obligations (including Reimbursement Obligations) and any breakage, termination or other
payments under Hedging Agreements constituting Secured Obligations and any interest accrued
thereon; and

          (e) Fifth, the balance, if any, to the person lawfully entitled thereto (including the
applicable Loan Party or its successors or assigns) or as a court of competent jurisdiction may
direct.

          In the event that any such proceeds are insufficient to pay in full the items described in
clauses (a) through (e) of this Section 8.03, the Loan Parties shall remain liable, jointly
and severally, for any deficiency. Each Loan Party acknowledges the relative rights, priorities
and agreements of the Secured Parties, as set forth in this Agreement, including as set forth in
this Section 8.03.

     SECTION 8.04 Right
 to Cure. Notwithstanding anything to the contrary contained
in Section 8.01, in the event that Borrower fails to comply with the requirements of
Section 6.10(a) or (b), until the expiration of the 10th day subsequent to the
date the certificate calculating such covenant is required to be delivered pursuant to
Section 5.01(c), Regency MLP shall have the right to issue Permitted Cure Securities for
cash or otherwise receive cash contributions to the capital of Regency MLP, and, in each case,
to contribute any such cash to the capital of Borrower (collectively, the “Cure Right”), and
upon the receipt by Borrower of such cash (the “Cure Amount”) pursuant to the exercise by
Regency MLP of such Cure Right such covenant shall be recalculated giving effect to the
following pro forma adjustments:

-107-

 

          (i) Consolidated EBITDA shall be increased, solely for the purpose of measuring such
covenants and not for any other purpose under this Agreement, by an amount equal to the Cure
Amount; and

          (ii) If, after giving effect to the foregoing recalculations, the Reporting Entity
shall then be in compliance with the requirements of all such covenants, the Reporting
Entity shall be deemed to have satisfied the requirements of such covenants as of the
relevant date of determination with the same effect as though there had been no failure to
comply therewith at such date, and the applicable breach or default of either such covenant
that had occurred shall be deemed cured for this purposes of the Agreement.

ARTICLE IX

THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT

     SECTION 9.01 Appointment and Authority. Each of the Lenders and the Issuing Bank hereby
irrevocably appoints UBS AG, Stamford Branch, to act on its behalf as the Administrative Agent and
the Collateral Agent hereunder and under the other Loan Documents and authorizes such Agents to
take such actions on its behalf and to exercise such powers as are delegated to such Agents 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 Collateral Agent, the Lenders and the Issuing Bank, and neither Borrower nor any other Loan
Party shall have rights as a third party beneficiary of any of such provisions.

     SECTION 9.02 Rights as a Lender. Each person serving as an 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 an Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly
indicated or unless the context otherwise requires, include each person serving as an 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 Borrower or any Subsidiary or other Affiliate thereof as if
such person were not an Agent hereunder and without any duty to account therefor to the Lenders.

     SECTION 9.03 Exculpatory Provisions. No Agent shall have any duties or obligations except
those expressly set forth herein and in the other Loan Documents. Without limiting the generality
of the foregoing, no Agent:

          (i) shall be subject to any fiduciary or other implied duties, regardless of whether a
Default has occurred and is continuing;

          (ii) shall have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated

-108-

 

hereby or by the other Loan Documents that such 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 such Agent shall not be required to take any action that, in its judgment or the
judgment of its counsel, may expose such Agent to liability or that is contrary to any Loan
Document or applicable Requirements of Law; and

          (iii) shall, 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 Borrower or any of its Affiliates that is communicated to or obtained by the
person serving as such Agent or any of its Affiliates in any capacity.

No Agent shall be liable for any action taken or not taken by it (x) 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 such Agent shall believe in good faith shall be necessary, under the circumstances
as provided in Section 10.02) or (y) in the absence of its own gross negligence or willful
misconduct. No Agent shall be deemed to have knowledge of any Default unless and until notice
describing such Default is given to such Agent by Borrower, a Lender or the Issuing Bank.

          No Agent shall 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 such Agent. Without limiting the
generality of the foregoing, the use of the term “agent” in this Agreement with reference to the
Administrative Agent or the Collateral Agent is not intended to connote any fiduciary or other
implied (or express) obligations arising under agency doctrine of any applicable law. Instead,
such term us used merely as a matter of market custom and is intended to create or reflect only an
administrative relationship between independent contracting parties.

     SECTION 9.04 Reliance by Agent. Each Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent, statement,
instrument, document or other writing (including any electronic message, Internet or intranet
website posting or other distribution) believed by it to be genuine and to have been signed, sent
or otherwise authenticated by the proper person. Each Agent also may rely upon any statement made
to it orally or by telephone and believed by it to have been made by the proper person, and shall
not incur any liability for relying thereon. In determining compliance with any condition
hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be
fulfilled to the satisfaction of a Lender or the Issuing Bank, the Administrative Agent may presume
that such condition is satisfactory to such Lender or the Issuing Bank unless the

-109-

 

Administrative Agent shall have received notice to the contrary from such Lender or the Issuing
Bank prior to the making of such Loan or the issuance of such Letter of Credit. Each Agent may
consult with legal counsel (who may be counsel for Borrower), independent accountants and other
experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts.

     SECTION 9.05 Delegation of Duties. Each 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 such Agent. Each 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 each Agent and any such sub-agent, and shall apply to their respective activities in
connection with the syndication of the credit facilities provided for herein as well as activities
as Agent.

     SECTION 9.06 Resignation of Agent. Each Agent may at any time give notice of its
resignation to the Lenders, the Issuing Bank and Borrower. Upon receipt of any such notice of
resignation, the Required Lenders shall have the right, in consultation with 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 Agent
gives notice of its resignation, then the retiring Agent may on behalf of the Lenders and the
Issuing Bank, appoint a successor Agent meeting the qualifications set forth above provided that if
the Agent shall notify 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 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
Collateral Agent on behalf of the Lenders or the Issuing Bank under any of the Loan Documents, the
retiring Collateral Agent shall continue to hold such collateral security as nominee until such
time as a successor Collateral Agent is appointed) and (2) all payments, communications and
determinations provided to be made by, to or through an Agent shall instead be made by or to each
Lender and the Issuing Bank directly, until such time as the Required Lenders appoint a successor
Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as
Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers,
privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be
discharged from all of its duties and obligations hereunder or under the other Loan Documents (if
not already discharged therefrom as provided above in this paragraph). The fees payable by
Borrower to a successor Agent shall be the same as those payable to its predecessor unless
otherwise agreed between Borrower and such successor. After the retiring Agent’s resignation
hereunder and under the other Loan Documents, the provisions of this Article IX and Section 10.03
shall continue in effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be taken by any of them
while the retiring Agent was acting as Agent.

-110-

 

     SECTION 9.07 Non-Reliance on Agent and Other Lenders. Each Lender and the Issuing Bank
acknowledges that it has, independently and without reliance upon any Agent or any other Lender and
based on such documents and information as it has deemed appropriate, made its own credit analysis
and decision to enter into this Agreement. Each Lender and the Issuing Bank also acknowledges that
it will, independently and without reliance upon any Agent or any other Lender 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.

     SECTION 9.08 No Other Duties, etc.; Appointment. Anything herein to the contrary
notwithstanding, none of the Bookmanagers, Arrangers, Syndication Agent or Documentation Agents
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, the Collateral Agent, a Lender or the Issuing Bank hereunder. The
Administrative Agent and Borrower may appoint additional or different Syndication Agents and
Documentation Agents and amend (or amend and restate) this Agreement to reflect such appointments
without the approval of any Lender other than any resigning Syndication Agent or Documentation
Agent.

be deemed to have been given when received; notices sent by telecopier shall be deemed to have been
given when sent (except that, if not given during normal business hours for the recipient, shall be

Notices delivered through electronic communications to the extent provided in paragraph (b) below,
shall be effective as provided in said paragraph (b).

-112-

 

          (b) Electronic Communications. Notices and other communications to the Lenders and
the Issuing Bank hereunder may (subject to Section 10.01(d)) be delivered or furnished
by electronic communication (including e-mail and Internet or intranet websites) pursuant to
procedures approved by the Administrative Agent; provided that the foregoing shall not apply to
notices to any Lender or the Issuing Bank pursuant to Article II if such Lender or the
Issuing Bank, as applicable, has notified the Administrative Agent that it is incapable of
receiving notices under such Article by electronic communication. The Administrative Agent, the
Collateral Agent or Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to procedures approved by
it (including as set forth in Section 10.01(d)); provided that approval of such
procedures may be limited to particular notices or communications.

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

          (c) Change of Address, Etc. Any party hereto may change its address or telecopier
number for notices and other communications hereunder by notice to the other parties hereto.

          (d) Posting. Each Loan Party hereby agrees that it will provide to the
Administrative Agent all information, documents and other materials that it is obligated to
furnish to the Administrative Agent pursuant to this Agreement and any other Loan Document,
including all notices, requests, financial statements, financial and other reports, certificates
and other information materials, but excluding any such communication that (i) relates to a
request for a new, or a conversion of an existing, Borrowing or other extension of credit
(including any election of an interest rate or interest period relating thereto), (ii) relates
to the payment of any principal or other amount due under this Agreement prior to the scheduled
date therefor, (iii) provides notice of any Default under this Agreement or (iv) is required to
be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or
any borrowing or other extension of credit hereunder (all such non-excluded communications,
collectively, the “Communications”), by transmitting the Communications in an electronic/soft
medium in a format reasonably acceptable to the Administrative Agent at
Christopher.aitkin@ubs.com or at such other e-mail address(es) provided to Borrower from time to
time or in such other form, including hard copy delivery thereof, as the Administrative Agent
shall require. In addition, each Loan Party agrees to continue to provide the Communications to
the Administrative Agent in the manner specified in this Agreement or any other Loan Document or
in such other form, including hard copy

-113-

 

delivery thereof, as the Administrative Agent shall require. Nothing in this Section
10.01 shall prejudice the right of the Agents, any Lender or any Loan Party to give any
notice or other communication pursuant to this Agreement or any other Loan Document in any other
manner specified in this Agreement or any other Loan Document or as any such Agent shall
require.

          To the extent consented to by the Administrative Agent in writing from time to time,
Administrative Agent agrees that receipt of the Communications by the Administrative Agent at its
e-mail address(es) set forth above shall constitute effective delivery of the Communications to the
Administrative Agent for purposes of the Loan Documents; provided that Borrower shall also deliver
to the Administrative Agent an executed original of each Compliance Certificate required to be
delivered hereunder.

          Each Loan Party further agrees that Administrative Agent may make the Communications available
to the Lenders by posting the Communications on Intralinks or a substantially similar electronic
transmission system (the “Platform”). The Platform is provided “as is” and “as available.” The
Agents do not warrant the accuracy or completeness of the Communications, or the adequacy of the
Platform and expressly disclaim liability for errors or omissions in the communications. No
warranty of any kind, express, implied or statutory, including, without limitation, any warranty of
merchantability, fitness for a particular purpose, non-infringement of third party rights or
freedom from viruses or other code defects, is made by any Agent in connection with the
Communications or the Platform. In no event shall the Administrative Agent or any of its Related
Parties have any liability to the Loan Parties, any Lender or any other person for damages of any
kind, including direct or indirect, special, incidental or consequential damages, losses or
expenses (whether in tort, contract or otherwise) arising out of any Loan Party’s or the
Administrative Agent’s transmission of communications through the Internet, except to the extent
the liability of such person is found in a final non-appealable judgment by a court of competent
jurisdiction to have resulted from such person’s gross negligence or willful misconduct.

     SECTION 10.02 Waivers; Amendment.

          (a) Generally. No failure or delay by any Agent, the Issuing Bank or any Lender in
exercising any right or power hereunder or under any other Loan Document shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights and remedies
of each Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies that they would otherwise have. No
waiver of any provision of any Loan Document or consent to any departure by any Loan Party
therefrom shall in any event be effective unless the same shall be permitted by this Section
10.02, and then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. Without limiting the generality of the foregoing, the making
of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default,
regardless of whether any Agent, any Lender or the Issuing Bank

-114-

 

may have had notice or knowledge of such Default at the time. No notice or demand on
Borrower in any case shall entitle Borrower to any other or further notice or demand in similar
or other circumstances.

          (b) Required Consents. Subject to Sections 10.02(c) and (d),
neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be
waived, amended, supplemented or modified except, in the case of this Agreement, pursuant to an
agreement or agreements in writing entered into by Borrower and the Required Lenders or, in the
case of any other Loan Document, pursuant to an agreement or agreements in writing entered into
by the Administrative Agent, the Collateral Agent (in the case of any Security Document) and the
Loan Party or Loan Parties that are party thereto, in each case with the written consent of the
Required Lenders; provided that no such agreement shall be effective if the effect thereof
would:

          (i) increase the Commitment of any Lender without the written consent of such Lender
(it being understood that no amendment, modification, termination, waiver or consent with
respect to any condition precedent, covenant or Default shall constitute an increase in the
Commitment of any Lender);

          (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of
interest thereon (other than interest pursuant to Section 2.06(c)), or reduce any
Fees payable hereunder, or change the form or currency of payment of any Obligation, without
the written consent of each Lender directly affected thereby (it being understood that any
amendment or modification to the financial definitions in this Agreement shall not
constitute a reduction in the rate of interest for purposes of this clause (ii));

          (iii) (A) change the scheduled final maturity of any Loan, (B) postpone the date for
payment of any Reimbursement Obligation or any interest or fees payable hereunder, (C)
change the amount of, waive or excuse any such payment (other than waiver of any increase in
the interest rate pursuant to Section 2.06(c)), or (D) postpone the scheduled date
of expiration of any Commitment or any Letter of Credit beyond the Revolving Maturity Date,
in any case, without the written consent of each Lender directly affected thereby;

          (iv) increase the maximum duration of Interest Periods hereunder, without the written
consent of each Lender directly affected thereby;

          (v) permit the assignment or delegation by Borrower of any of its rights or obligations
under any Loan Document, without the written consent of each Lender;

          (vi) release Regency MLP or all or substantially all of the Subsidiary Guarantors from
their Guarantee (except as expressly provided in Article VII), or limit their
liability in respect of such Guarantee, without the written consent of each Lender;

-115-

 

          (vii) release all or substantially all of the Collateral from the Liens of the Security
Documents or alter the relative priorities of the Secured Obligations entitled to the Liens
of the Security Documents, in each case without the written consent of each Lender (it being
understood that additional Classes of Loans pursuant to Sections 2.19 and
2.20 or consented to by the Required Lenders may be equally and ratably secured by
the Collateral with the then existing Secured Obligations under the Security Documents);

          (viii) change Section 2.14(b) or (c) in a manner that would alter the
pro rata sharing of payments or setoffs required thereby or any other provision in a manner
that would alter the pro rata allocation among the Lenders of Loan disbursements, including
the requirements of Sections 2.02(a), 2.17(d) and 2.18(d), without
the written consent of each Lender directly affected thereby;

          (ix) change any substantive provision of this Section 10.02(b) or Section
10.02(c) or (d), without the written consent of each Lender directly affected
thereby (except for additional restrictions on amendments or waivers for the benefit of
Lenders of additional Classes of Loans pursuant to Section 2.19 or consented to by
the Required Lenders);

          (x) change the percentage set forth in the definition of “Required Lenders,” “Required
Class Lenders,” “Required Revolving Lenders” or any other provision of any Loan Document
(including this Section) specifying the number or percentage of Lenders (or Lenders of any
Class) required to waive, amend or modify any rights thereunder or make any determination or
grant any consent thereunder, without the written consent of each Lender (or each Lender of
such Class, as the case may be), other than to increase such percentage or number or to give
any additional Lender or group of Lenders such right to waive, amend or modify or make any
such determination or grant any such consent;

          (xi) change the application of prepayments as among or between Classes under
Section 2.10(e), without the written consent of the Required Class Lenders of each
Class that is being allocated a lesser prepayment as a result thereof (it being understood
that the Required Lenders may waive, in whole or in part, any prepayment so long as the
application, as between Classes, of any portion of such prepayment that is still required to
be made is not changed and, if additional Classes of Term Loans under this Agreement
pursuant to Section 2.19 or consented to by the Required Lenders are made, such new
Term Loans may be included on a pro rata basis in the various prepayments required pursuant
to Section 2.10(e));

          (xii) change or waive any provision of Article X as the same applies to any
Agent, or any other provision hereof as the same applies to the rights or obligations of any
Agent, in each case without the written consent of such Agent;

          (xiii) change or waive any obligation of the Lenders relating to the issuance of or
purchase of participations in Letters of Credit, without the written consent of the Required
Revolving Lenders, the Administrative Agent and the Issuing Bank;

-116-

 

          (xiv) change or waive any provision hereof relating to Swingline Loans (including the
definition of “Swingline Commitment”), without the written consent of the Swingline Lender;
or

          (xv) expressly change or waive any condition precedent in Section 4.02 to any
Revolving Borrowing without the written consent of the Required Revolving Lenders.

Notwithstanding anything in this Section 10.02 to the contrary, any Increase Joinder or
Revolving Loan Joinder may, without the consent of any Lenders other than those participating in
such joinder, effect such amendments to this Agreement and the other Loan Documents as may be
necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of
Section 2.19 or 2.20, as applicable.

          (c) Collateral. Without the consent of any other person, the applicable Loan Party
or Parties and the Administrative Agent and/or Collateral Agent may (in its or their respective
sole discretion, or shall, to the extent required by any Loan Document) enter into any amendment
or waiver of any Loan Document, or enter into any new agreement or instrument, to effect the
granting, perfection, protection, expansion or enhancement of any security interest in any
Collateral or additional property to become Collateral for the benefit of the Secured Parties,
or as required by local law to give effect to, or protect any security interest for the benefit
of the Secured Parties, in any property or so that the security interests therein comply with
applicable Requirements of Law.

          (d) Dissenting Lenders. If, in connection with any proposed change, waiver,
discharge or termination of the provisions of this Agreement as contemplated by Section
10.02(b), the consent of the Required Lenders is obtained but the consent of one or more of
such other Lenders whose consent is required is not obtained, then Borrower shall have the right
to replace such non-consenting Lender or Lenders, so long as all non-consenting Lenders are so
replaced (or, at the option of Borrower if the respective non-consenting Lenders’ consent is
required with respect to less than all Classes of Loans (or related Commitments), to replace
only the Commitments and/or Loans of the respective non-consenting Lender that gave rise to the
need to obtain such Lender’s individual consent), with one or more persons pursuant to
Section 2.16 so long as at the time of such replacement each such new Lender consents to
the proposed change, waiver, discharge or termination.

     SECTION 10.03 Expenses; Indemnity; Damage Waiver.

          (a) Costs and Expenses. Borrower shall pay (i) all reasonable out-of-pocket
expenses incurred by the Administrative Agent, the Collateral Agent and their respective
Affiliates (including the reasonable fees, charges and disbursements of counsel, and local
counsel who specialize in gas and pipeline matters, for the Administrative Agent and/or the
Collateral Agent) in connection with the syndication of the credit facilities provided for
herein (including the obtaining and maintaining of CUSIP numbers for the Loans), the
preparation, negotiation, execution, delivery and administration of this Agreement and the other
Loan Documents or any amendments, modifications or waivers of the provisions hereof

-117-

 

or thereof (whether or not the transactions contemplated hereby or thereby shall be
consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in
connection with the issuance, amendment, renewal or extension of any Letter of Credit or any
demand for payment thereunder, (iii) all out-of-pocket expenses incurred by the Administrative
Agent, the Collateral Agent, any Lender or the Issuing Bank (including the fees, charges and
disbursements of any counsel, and local counsel who specialize in gas and pipeline matters, for
the Administrative Agent, the Collateral Agent, any Lender or the Issuing Bank), in connection
with the enforcement or protection of its rights (A) in connection with this Agreement and the
other Loan Documents, including its rights under this Section 10.03, or (B) in
connection with the Loans made or Letters of Credit issued hereunder, including all such
out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of
such Loans or Letters of Credit and (iv) all documentary and similar taxes and charges in
respect of the Loan Documents.

          (b) Indemnification by Borrower. Borrower shall indemnify the Administrative Agent
(and any sub-agent thereof), the Collateral Agent (and any sub-agent thereof) each Lender and
the Issuing Bank, and each Related Party of any of the foregoing persons (each such person being
called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses,
claims, damages, liabilities and related expenses (including the fees, charges and disbursements
of any counsel, and local counsel who specialize in gas and pipeline matters, for any
Indemnitee) incurred by any Indemnitee or asserted against any Indemnitee by any third party or
by Borrower or any other Loan Party arising out of, in connection with, or as a result of (i)
the execution or delivery of this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the performance by the parties hereto of their
respective obligations hereunder or thereunder or the consummation of the transactions
contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use or proposed use of
the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment
under a Letter of Credit if the documents presented in connection with such demand do not
strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence
or Release or threatened Release of Hazardous Materials on, at, under or from any property
owned, leased or operated by any Company at any time, or any Environmental Claim related in any
way to any Company, 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 Borrower or any other Loan Party, and regardless
of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related
expenses (x) are determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or
(y) result from a claim brought by Borrower or any other Loan Party against an Indemnitee for
breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document,
if Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on
such claim as determined by a court of competent jurisdiction; provided, further, that Borrower
shall not be required to reimburse the legal fees and expenses of more than one outside counsel
(in addition to any reasonably necessary special counsel and up to one local counsel in each

-118-

 

applicable local jurisdiction) for all Indemnitees unless, in the reasonable written
opinion of outside counsel to such Indemnitees, representation of all such Indemnitees would be
inappropriate due to the existence of an actual or potential conflict of interest.

          (c) Reimbursement by Lenders. To the extent that Borrower for any reason fails to
indefeasibly pay any amount required under paragraph (a) or (b) of this Section 10.03 to
be paid by it to the Administrative Agent (or any sub-agent thereof), the Collateral Agent, the
Issuing Bank, the Swingline Lender or any Related Party of any of the foregoing, each Lender
severally agrees to pay to the Administrative Agent (or any such sub-agent), the Collateral
Agent (or any sub-agent thereof), the Issuing Bank, the Swingline Lender or such Related Party,
as the case may be, such Lender’s pro rata share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the
unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the
case may be, was incurred by or asserted against the Administrative Agent (or any such
sub-agent), the Collateral Agent (or any sub-agent thereof), the Swingline Lender or the Issuing
Bank 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), the Collateral Agent (or any sub-agent
thereof), the Swingline Lender or Issuing Bank in connection with such capacity. The
obligations of the Lenders under this paragraph (c) are subject to the provisions of Section
2.14. For purposes hereof, a Lender’s “pro rata share” shall be determined based upon its
share of the sum of the total Revolving Exposure, outstanding Term Loans and unused Commitments
at the time.

          (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable Requirements of Law, no Loan Party shall assert, and each Loan Party hereby waives,
any claim against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or
Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in paragraph (b)
above shall be liable for any damages arising from the use by unintended recipients of any
information or other materials distributed by it through telecommunications, electronic or other
information transmission systems in connection with this Agreement or the other Loan Documents
or the transactions contemplated hereby or thereby.

          (e) Payments. All amounts due under this Section shall be payable not later than 3
Business Days after demand therefor.

     SECTION 10.04 Successors and Assigns.

          (a) Successors and Assigns Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that Borrower may not assign or otherwise transfer any of its
rights or obligations hereunder without the prior written consent of the Administrative Agent,
the Collateral Agent, the Issuing Lender, the Swingline Lender and

-119-

 

each Lender and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b)
of this Section 10.04, (ii) by way of participation in accordance with the provisions of
paragraph (d) of this Section 10.04 or (iii) by way of pledge or assignment of a
security interest subject to the restrictions of paragraph (f) of this Section (and any other
attempted assignment or transfer by Borrower or any Lender 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 paragraph (d) of this Section and, to the extent expressly contemplated
hereby, the other Indemnitees) 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 at the time owing to it); provided
that

          (i) except in the case of any assignment made in connection with the primary
syndication of the Commitment and Loans by the Arranger or an assignment of the entire
remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it
or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund
with respect to a Lender, the aggregate amount of the Commitment (which for this purpose
includes Loans outstanding thereunder) or, if the applicable Commitment is not then in
effect, the principal outstanding balance of the Loans of the assigning Lender subject to
each such assignment (determined as of the date the Assignment and Assumption with respect
to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified
in the Assignment and Assumption, as of the Trade Date) shall not be less than $5.0 million,
in the case of any assignment in respect of Revolving Loans and/or Revolving Commitments, or
$1.0 million, in the case of any assignment in respect of Term Loans and/or Term Loan
Commitments, unless each of the Administrative Agent and, so long as no Event of Default has
occurred and is continuing, Borrower otherwise consent (each such consent not to be
unreasonably withheld or delayed);

          (ii) each partial assignment shall be made as an assignment of a proportionate part of
all the assigning Lender’s rights and obligations under this Agreement with respect to the
Loan or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender
from assigning all or a portion of its rights and obligations among separate tranches on a
non-pro rata basis; and

          (iii) the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation fee of
$3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire.

-120-

 

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c)
of this Section 10.04, 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 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 2.12, 2.13, 2.15
and 10.03 with respect to facts and circumstances occurring prior to the effective date of
such assignment. Any assignment or transfer by a Lender of rights or obligations under this
Agreement that does not comply with this paragraph 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
paragraph (d) of this Section 10.04.

          (c) Register. The Administrative Agent, acting solely for this purpose as an agent
of Borrower, shall maintain at one of its offices in Stamford, Connecticut 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 LC
Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the
“Register”). The entries in the Register shall be conclusive, and Borrower, the Administrative
Agent, the Issuing Bank and the Lenders shall 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
Borrower, the Issuing Bank, the Collateral Agent, the Swingline Lender and any Lender (with
respect to its own interest only), 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, Borrower, the Administrative Agent, the Issuing Bank or the Swingline Lender sell
participations to any person (other than a natural person or Borrower or any of Borrower’s
Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights
and/or obligations under this Agreement (including all or a portion of its Commitment and/or the
Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto
for the performance of such obligations and (iii) Borrower, the Administrative Agent and the
Lenders and Issuing Bank shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement.

          Any agreement or instrument pursuant to which a Lender sells such a participation shall
provide that such Lender shall retain the sole right to enforce the Loan Documents and to approve
any amendment, modification or waiver of any provision of the Loan Documents; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in clause (i), (ii) or (iii)
of the first proviso to Section 10.02(b) that affects such

-121-

 

Participant. Subject to paragraph (e) of this Section, Borrower agrees that each Participant
shall be entitled to the benefits of Sections 2.12, 2.13 and 2.15 (subject
to the requirements of those Sections) to the same extent as if it were a Lender and had acquired
its interest by assignment pursuant to paragraph (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 on Participant Rights. A Participant shall not be entitled to
receive any greater payment under Sections 2.12, 2.13 and 2.15 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
Borrower’s prior written consent.

          (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 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. In the
case of any Lender that is a fund that invests in bank loans, such Lender may, without the
consent of Borrower or the Administrative Agent, collaterally assign or pledge all or any
portion of its rights under this Agreement, including the Loans and Notes or any other
instrument evidencing its rights as a Lender under this Agreement, to any holder of, trustee
for, or any other representative of holders of, obligations owed or securities issued, by such
fund, as security for such obligations or securities.

     SECTION 10.05 Survival of Agreement. All covenants, agreements, representations and
warranties made by the Loan Parties in the Loan Documents and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement or any other Loan Document
shall be considered to have been relied upon by the other parties hereto and shall survive the
execution and delivery of the Loan Documents and the making of any Loans and issuance of any
Letters of Credit, regardless of any investigation made by any such other party or on its behalf
and notwithstanding that the Agents, the Issuing Bank or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any credit is extended
hereunder, and shall continue in full force and effect as long as the principal of or any accrued
interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and
unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or
terminated. The provisions of Sections 2.12, 2.14, 2.15 and Article
X shall survive and remain in full force and effect regardless of the consummation of the
transactions contemplated hereby, the repayment of the Loans, the payment of the Reimbursement
Obligations, the expiration or termination of the Letters of Credit and the Commitments or the
termination of this Agreement or any provision hereof.

     SECTION 10.06 Counterparts; Integration; Effectiveness; Electronic Execution.

-122-

 

          (a) 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, and any separate letter agreements with respect to
fees payable to the Administrative Agent, 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. This Agreement shall
become effective when the conditions set forth in Section 4.01 are satisfied, and at
such time, the signatures of the Agents and the Loan Parties to the Existing Credit Agreement
shall be deemed to be the signatures of such Agents and Loan Parties to this Agreement.
Borrower, the Guarantors, the Agents and the Lenders agree that (i) all obligations under the
Existing Credit Agreement executed on the Second Amendment Effectiveness Date, that is amended
and restated hereby, shall continue to exist under and be evidenced by this Agreement and the
other Loan Documents and shall constitute Obligations and (ii) except as expressly stated herein
or amended, the other Loan Documents are ratified and confirmed as remaining unmodified and in
full force and effect with respect to all Secured Obligations. Delivery of an executed
counterpart of a signature page of this Agreement by telecopier shall be effective as delivery
of a manually executed counterpart of this Agreement.

          (b) 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 Requirement of 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.

     SECTION 10.07 Severability. Any provision of this Agreement held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

     SECTION 10.08 Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender, the Issuing Bank, and each of their respective Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by applicable
Requirements of Law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final, in whatever currency) at any time held and other obligations (in whatever
currency) at any time owing by such Lender, the Issuing Bank or any such Affiliate to or for the
credit or the account of Borrower or any other Loan Party against any and all of the obligations of
Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan
Document to such Lender or the Issuing Bank, irrespective of whether or not such Lender or the
Issuing Bank shall have made any demand under this Agreement or any other

-123-

 

Loan Document and although such obligations of Borrower or such Loan Party may be contingent or
unmatured or are owed to a branch or office of such Lender or the Issuing Bank different from the
branch or office holding such deposit or obligated on such indebtedness. The rights of each
Lender, the Issuing Bank and their respective Affiliates under this Section are in addition to
other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank or
their respective Affiliates may have. Each Lender and the Issuing Bank agrees to notify 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.

     SECTION 10.09 Governing Law; Jurisdiction; Consent to Service of Process.

          (a) Governing Law. This Agreement shall be construed in accordance with and
governed by the law of the State of New York, without regard to conflicts of law principles that
would require the application of the laws of another jurisdiction.

          (b) Submission to Jurisdiction. Each Loan Party hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the
Supreme Court of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court from any thereof,
in any action or proceeding arising out of or relating to any Loan Document, or for recognition
or enforcement of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or proceeding may be heard
and determined in such New York State court or, to the fullest extent permitted by applicable
law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on
the judgment or in any other manner provided by law. Nothing in this Agreement or any other
Loan Document shall affect any right that the Administrative Agent, the Issuing Bank or any
Lender may otherwise have to bring any action or proceeding relating to this Agreement or any
other Loan Document against any Loan Party or its properties in the courts of any jurisdiction.

          (c) Waiver of Venue. Each Loan Party hereby irrevocably and unconditionally
waives, to the fullest extent permitted by applicable Requirements of Law, any objection which
it may now or hereafter have to the laying of venue of any suit, action or proceeding arising
out of or relating to this Agreement or any other Loan Document in any court referred to in
Section 10.09(b). Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by applicable Requirements of 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 any action or proceeding arising out of or relating to any Loan Document, in the
manner provided for notices (other than telecopier) in Section 10.01. Nothing in this
Agreement or any other Loan Document will affect the right of any party hereto to serve process
in any other manner permitted by applicable Requirements of Law.

-124-

 

     SECTION 10.10 Waiver of Jury Trial. Each Loan Party hereby waives, to the fullest extent
permitted by applicable Requirements of 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, any other Loan
Document or the transactions contemplated hereby (whether based on contract, tort or any other
theory). Each party hereto (a) certifies that no representative, agent or attorney of any other
party has represented, expressly or otherwise, that such other party 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 by, among other things, the mutual waivers
and certifications in this Section.

     SECTION 10.11 Headings. Article and Section headings and the Table of Contents used herein
are for convenience of reference only, are not part of this Agreement and shall not affect the
construction of, or be taken into consideration in interpreting, this Agreement.

     SECTION 10.12 Treatment of Certain Information; Confidentiality. Each of the
Administrative Agent, the Lenders and the Issuing Bank 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 other 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 or its Affiliates (including any self-regulatory authority, such as the
National Association of Insurance Commissioners), (c) to the extent required by applicable
Requirements of Law or by any subpoena or similar legal process, (d) to any other party hereto, (e)
in connection with the exercise of any remedies hereunder or under any other Loan Document or any
action or proceeding relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section 10.12, 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 actual or prospective counterparty (or its advisors) to any swap or derivative transaction
relating to Borrower and its obligations or (iii) any rating agency for the purpose of obtaining a
credit rating applicable to any Lender, (g) with the consent of 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, the Issuing Bank or any of their
respective Affiliates on a nonconfidential basis from a source other than Borrower. For purposes
of this Section, “Information” means all information received from Holdings or any of its
Subsidiaries relating to Holdings or any of its Subsidiaries or any of their respective businesses,
other than any such information that is available to the Administrative Agent, any Lender or the
Issuing Bank on a nonconfidential basis prior to disclosure by Holdings or any of its Subsidiaries;
provided that, in the case of information received from Holdings or any of its Subsidiaries after
the Closing Date, such information is clearly identified at the time of delivery as confidential.
Any person required to maintain the confidentiality of Information as provided in this Section
shall be considered to have complied with its obligation to do so if such person has exercised the
same degree of care to maintain the

-125-

 

confidentiality of such Information as such person would accord to its own confidential
information.

     SECTION 10.13 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 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 Borrower, which information includes the name, address and
tax identification number of Borrower and other information regarding Borrower that will allow such
Lender or the Administrative Agent, as applicable, to identify Borrower in accordance with the Act.
This notice is given in accordance with the requirements of the Act and is effective as to the
Lenders and the Administrative Agent.

     SECTION 10.14 Interest Rate Limitation. Notwithstanding anything herein to the contrary,
if at any time the interest rate applicable to any Loan, together with all fees, charges and other
amounts which are treated as interest on such Loan under applicable Requirements of Law
(collectively, the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may
be contracted for, charged, taken, received or reserved by the Lender holding such Loan in
accordance with applicable Requirements of Law, the rate of interest payable in respect of such
Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in
respect of such Loan but were not payable as a result of the operation of this Section shall be
cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods
shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been
received by such Lender.

     SECTION 10.15 Lender Addendum. Each Lender that became a party to the Original Credit
Agreement on the Closing Date, the First Amended and Restated Credit Agreement on the First
Amendment Effectiveness Date or the Existing Credit Agreement on the Second Amendment Effectiveness
Date did so by delivering to the Administrative Agent a Lender Addendum.

     SECTION 10.16 Obligations Absolute. To the fullest extent permitted by applicable
Requirements of Law, all obligations of the Loan Parties hereunder shall be absolute and
unconditional irrespective of:

          (a) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition,
liquidation or the like of any Loan Party;

          (b) any lack of validity or enforceability of any Loan Document or any other agreement or
instrument relating thereto against any Loan Party;

          (c) any change in the time, manner or place of payment of, or in any other term of, all or
any of the Obligations, or any other amendment or waiver of or any consent to

-126-

 

any departure from any Loan Document or any other agreement or instrument relating thereto;

          (d) any exchange, release or non-perfection of any other Collateral, or any release or
amendment or waiver of or consent to any departure from any guarantee, for all or any of the
Obligations;

          (e) any exercise or non-exercise, or any waiver of any right, remedy, power or privilege
under or in respect hereof or any Loan Document; or

          (f) any other circumstances which might otherwise constitute a defense available to, or a
discharge of, the Loan Parties.
