                                   ARTICLE II
                                   THE CREDITS

     SECTION 2.01 COMMITMENTS. Subject to the terms and conditions and relying
upon the representations and warranties herein set forth, each Lender agrees,
severally and not jointly:

          (a) to continue its Term Loans to Borrower on the MLP Effectiveness
Date, in the principal amount not to exceed the amount outstanding on such date;
and

          (b) to make Revolving Loans to Borrower, at any time and from time to
time on or after the Closing Date until the earlier of the Revolving Maturity
Date and the termination of the Revolving Commitment of such Lender in
accordance with the terms hereof, in an aggregate principal amount at any time
outstanding that will not result in such Lender's Revolving Exposure exceeding
such Lender's Revolving Commitment.

          Amounts paid or prepaid in respect of Term Loans may not be
reborrowed. Within the limits set forth in clause (b) above and subject to the
terms, conditions and limitations set forth herein, Borrower may borrow, pay or
prepay and reborrow Revolving Loans.

     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 responsible for
the failure of any other Lender to make any Loan required to be made by such
other Lender). Except for Loans deemed made pursuant to Section 2.18(e)(ii), (x)
ABR Loans comprising any Borrowing shall be in an aggregate principal amount
that is (i) an integral multiple of $500,000 and not less than $1.0 million or
(ii) equal to the remaining available balance of the applicable Commitments and
(y) the Eurodollar Loans comprising any Borrowing shall be in an aggregate
principal amount that is (i) an integral multiple of $1.0 million and not less
than $5.0 million or (ii) equal to the remaining available balance of the
applicable Commitments.

          (b) Subject to Sections 2.11 and 2.12, each Borrowing shall be
comprised entirely of ABR Loans or Eurodollar Loans as Borrower may request
pursuant to


                                      -36-

<PAGE>

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) whether the requested Borrowing is to be a Borrowing of Revolving
Loans or Term Loans;

          (b) the aggregate amount of such Borrowing;

          (c) the date of such Borrowing, which shall be a Business Day;

          (d) whether such Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing;

          (e) in the case of a Eurodollar Borrowing, the initial Interest Period
to be applicable thereto, which shall be a period contemplated by the definition

satisfied as of the date of the notice.

          If no election as to the Type of Borrowing is specified, then the
requested Borrowing shall be an ABR Borrowing. If no Interest Period is
specified with respect to any requested Eurodollar Borrowing, then Borrower
shall be deemed to have selected an Interest Period of one month's duration.
Promptly following receipt of a Borrowing Request in accordance with this
Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender's Loan to be made as part of the
requested Borrowing.

     SECTION 2.04 EVIDENCE OF DEBT; REPAYMENT OF LOANS.

          (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-

<PAGE>

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

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

of 360 days and shall be payable for the actual number of days elapsed

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-

(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.

          (a) ABR Loans. Subject to the provisions of Section 2.06(c), the Loans
comprising each ABR Borrowing, including each Swingline Loan, shall bear

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

such Borrowing plus the Applicable Margin in effect from time to time.

<PAGE>

          (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

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,

          (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,

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

          (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

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-

<PAGE>

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-

<PAGE>

               (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-

<PAGE>

     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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

          (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-

<PAGE>

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-

<PAGE>

               (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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

               (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-

<PAGE>

     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-

<PAGE>

     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-

<PAGE>

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-

<PAGE>

          (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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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

     Commitments; and


                                      -64-

<PAGE>

               (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-

<PAGE>

     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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

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-

<PAGE>

               (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

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 the grantors thereunder in the Security Agreement Collateral
(other than such Security Agreement Collateral in which a security interest
cannot be perfected under the UCC as in effect at the 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 is filed in the United States Copyright Office, the Liens created
by such Security Agreement shall constitute fully perfected First Priority Liens
on, and security interests in, all right, 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

<PAGE>

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 enforceable Liens on, and security interests in, all of the Loan
Parties' right, title and interest in and to the Collateral thereunder, and when
all appropriate filings or recordings are made in the appropriate offices as may
be required under applicable law, such Security Document will constitute First
Priority fully perfected Liens on, and security interests in, all right, title
and interest of the Loan Parties in such Collateral, in each case subject to no

of the Code, which investment would or could reasonably be expected to trigger a
material increase in the net income of a United States shareholder of such
Subsidiary pursuant to Section 951 (or a successor provision) of the Code;

Party which lease individually has a fair market value of at least $5.0 million,

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 perfected First
Priority Liens subject only to Permitted Collateral Liens or other Liens
acceptable to the Collateral Agent. The Mortgages or instruments related thereto

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 shall be paid in

Agent or the Collateral Agent shall reasonably require to confirm the validity,
perfection and priority of the Lien of any existing Mortgage or new Mortgage

form and substance reasonably satisfactory to the Administrative Agent and the
Collateral Agent) in respect of such Mortgage).

          (d) Promptly grant to the Collateral Agent, within 60 days (subject to

unless the Collateral Agent otherwise consents, each leased Pipeline of such
Loan Party which lease together with any related unmortgaged Pipeline leases has
a fair market value of at least $5.0 million, in each case, as additional
security for the 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 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 shall be paid in full. Such Loan Party
shall otherwise take such actions and execute and/or deliver to the Collateral
Agent such documents as the Administrative Agent or the Collateral Agent shall
reasonably require to confirm the validity, perfection and priority of the Lien

record, or cause to be registered, filed or recorded, in an appropriate
governmental office, any document or instrument supplemental to or confirmatory
of the Security 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


                                      -84-

<PAGE>

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

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

agreement was not entered into in contemplation of such person becoming a
Subsidiary or (e) is imposed by any amendments or refinancings that are
otherwise permitted by the Loan Documents of the contracts, instruments or
obligations referred to in clause (3) or (4)(d); provided that such amendments
and refinancings are no more materially restrictive with respect to such
prohibitions and limitations than those prior to such amendment or refinancing.

                                   ARTICLE VII
                                    GUARANTEE

     SECTION 7.01 THE GUARANTEE. The Guarantors hereby jointly and severally
guarantee, as a primary obligor and not as a surety to each Secured Party and
their respective successors and assigns, the prompt payment in full when due
(whether at stated maturity, by required prepayment, declaration, demand, by
acceleration or otherwise) of the principal of and interest (including any
interest, fees, costs or charges that would accrue but for the provisions of the
Title 11 of the United States Code after any bankruptcy or insolvency petition
under Title 11 of the United States Code) on the Loans made by the Lenders to,
and the Notes held by each Lender of, Borrower, and all other Secured
Obligations from time to time owing to the Secured Parties by any Loan Party
under any Loan Document or any Hedging Agreement entered into with a
counterparty that is a Secured Party, in each case strictly in accordance with
the terms thereof (such obligations being herein collectively called the
"Guaranteed Obligations"). The Guarantors hereby jointly and severally agree
that if Borrower or other Guarantor(s) shall fail to pay in full when due
(whether at stated maturity, by acceleration or otherwise) any of the Guaranteed
Obligations, the Guarantors will promptly pay the same in cash, without any
demand or notice whatsoever, and that in the case of any extension of time of
payment or renewal of any of the Guaranteed Obligations, the same will be
promptly paid in full when due (whether at


                                      -100-

<PAGE>

extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

     SECTION 7.02 OBLIGATIONS UNCONDITIONAL. The obligations of the Guarantors
under Section 7.01 shall constitute a guaranty of payment and to the fullest
extent permitted by applicable Requirements of Law, are absolute, irrevocable
and unconditional, joint and several, irrespective of the value, genuineness,
validity, regularity or enforceability of the Guaranteed Obligations of Borrower
under this Agreement, the Notes, if any, or any other agreement or instrument
referred to herein or therein, or any substitution, release or exchange of any
other guarantee of or security for any of the Guaranteed Obligations, and,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or Guarantor
(except for payment in full). Without limiting the generality of the foregoing,
it is agreed that the occurrence of any one or more of the following shall not
alter or impair the liability of the 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 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


                                     -101-

<PAGE>

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.

     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


                                     -102-

<PAGE>

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
                                EVENTS OF DEFAULT

     SECTION 8.01 EVENTS OF DEFAULT. Upon the occurrence and during the
continuance of the following events ("Events of Default"):

          (a) default shall be made in the payment of any principal of any Loan
or any Reimbursement Obligation when and as the same shall become due and
payable, whether at the due date thereof or at a date fixed for prepayment
(whether voluntary or mandatory) thereof or by acceleration thereof or
otherwise;

          (b) default shall be made in the payment of any interest on any Loan

Obligations), when and as the same shall become due and payable beyond any
applicable grace period, or (ii) fail to observe or perform any other term,

of such Indebtedness or a trustee or other representative on its or their behalf
(with or without the giving of notice, the lapse of time or both) to cause, such
Indebtedness to become due prior to its stated maturity or become subject to a
mandatory offer purchase by the obligor; provided that it shall not constitute
an 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

apply for or consent to the appointment of a receiver, trustee, custodian,
sequestrator, conservator or


                                     -104-

for the benefit of creditors; (vi) admit in writing its inability or fail

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,

          (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

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

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:


                                     -105-

<PAGE>

(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 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;


                                     -106-

<PAGE>

          (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 (a). 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:

               (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


                                     -107-

<PAGE>

     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 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 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.

     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


                                     -110-

<PAGE>

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.

Notices sent by hand or overnight courier service, or mailed by certified or
registered mail, shall be deemed to have been given when received; notices sent

          (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


                                     -112-

<PAGE>

notices and other communications to it hereunder by electronic communications
pursuant to procedures approved by it (including as set forth in Section

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

          (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 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


                                     -113-

<PAGE>

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 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


                                     -114-

<PAGE>

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;

               (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);


                                     -115-

<PAGE>

               (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;

               (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


                                     -116-

<PAGE>

               (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 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


                                     -117-

<PAGE>

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 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.


                                     -118-

<PAGE>

          (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 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


                                     -119-

<PAGE>

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.

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


                                     -120-

<PAGE>

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
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


                                     -121-

<PAGE>

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.

          (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


                                     -122-

<PAGE>

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 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


                                     -123-

<PAGE>

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.

     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


                                     -124-

<PAGE>

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 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


                                     -125-

<PAGE>

(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 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;


                                     -126-

<PAGE>
