rating organization) ("S&P"), or Moody's Investors Service, Inc. (or any

recently ended as of such date and for the Calculation Period ended on such last
day, and any change (x) shall become effective upon the delivery to the
Administrative Agent of a certificate of a Responsible Officer of the Borrower
(which certificate may be delivered prior to delivery of the relevant financial
statements or may be incorporated in the certificate delivered pursuant to
subsection 7.2(b)) with respect to the financial statements to be delivered
pursuant to Section 7.1 for the most recently ended fiscal quarter (a) setting

at any time during which the Borrower has failed to deliver the certificate
referred to above in this definition as required under subsection 7.2(b) with
respect to a fiscal quarter following the date the delivery thereof is due, the
Leverage Ratio shall be deemed, solely for the purposes of this definition, to
be greater than 4.0 to 1.0 until such time as Borrower shall deliver such
compliance certificate.

Section 2.1 Revolving Credit Commitments.

                  (a) Subject to the terms and conditions hereof, each Lender
severally agrees to make revolving credit loans ("Revolving Credit Loans") to
the Borrower from time to time during the Revolving Credit Commitment Period in
an aggregate principal amount at any one time outstanding which, when added to
such Lender's Commitment Percentage of the then outstanding L/C Obligations,
does not exceed the amount of such Lender's Revolving Credit Commitment,
provided that no such Revolving Credit Loan shall be made if, after giving
effect thereto, Section 2.4 would be contravened. During the Revolving Credit
Commitment Period the Borrower may use the Revolving Credit Commitments by
borrowing, prepaying the Revolving Credit Loans in whole or in part, and
reborrowing, all in accordance with the terms and conditions hereof.

                  (b) The Revolving Credit Loans may from time to time be (i)
Eurodollar Loans, (ii) Alternate Base Rate Loans or (iii) a combination thereof,
as determined by the Borrower and notified to the Administrative Agent in
accordance with Sections 2.3 and 4.2, provided that no Revolving Credit Loan
shall be made as a Eurodollar Loan after the day that is one month prior to the
Revolving Credit Termination Date.

                  (c) The revolving credit loans outstanding on the Closing Date
under the Existing Credit Agreement shall continue to be outstanding and shall
be continued Revolving Credit Loans under this Agreement.

Section 2.2 Repayment of Loans; Evidence of Debt.

                  (a) The Borrower hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Revolving Credit Loan on the Revolving Credit Termination Date.

                  (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing the indebtedness of the Borrower to
such Lender resulting from each Revolving Credit Loan made by such Lender,
including the amounts of principal and interest payable and paid to such Lender
from time to time hereunder.

                  (c) The Administrative Agent shall maintain accounts in which
it shall record (i) the amount of each Revolving Credit Loan made hereunder, the
Type thereof and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to

                                       21
<PAGE>

become due and payable from the 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.

                  (d) The entries made in the accounts maintained pursuant to
paragraph (b) or (c) of this Section 2.2 shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; 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 obligation of the Borrower
to repay the Revolving Credit Loans in accordance with the terms of this
Agreement.

                  (e) Any Lender may request that Revolving Credit Loans made by
it be evidenced by a promissory note. In such event, the Borrower shall prepare,
execute and deliver to such Lender a promissory note substantially in the form
of Exhibit A hereto (a "Revolving Credit Note") payable to the order of such
Lender (or, if requested by such Lender, to such Lender and its registered
assigns). Thereafter, the Revolving Credit Loans evidenced by such promissory
note and interest thereon shall at all times (including after assignment
pursuant to Section 11.6) 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 2.3 Procedure for Revolving Credit Borrowing. The Borrower may
borrow under the Revolving Credit Commitments during the Revolving Credit
Commitment Period on any Working Day, if all or any part of the requested
Revolving Credit Loans are to be initially Eurodollar Loans, or on any Business
Day, otherwise, provided that the Borrower shall give the Administrative Agent
irrevocable notice (which notice must be received by the Administrative Agent
prior to 10:00 A.M., New York City time, (a) three Working Days prior to the
requested Borrowing Date, if all or any part of the requested Revolving Credit
Loans are to be initially Eurodollar Loans, or (b) one Business Day prior to the
requested Borrowing Date, otherwise), specifying (i) the amount to be borrowed,
(ii) the requested Borrowing Date, (iii) whether the borrowing is to be of
Eurodollar Loans, Alternate Base Rate Loans or a combination thereof, and (iv)
if the borrowing is to be entirely or partly of Eurodollar Loans, the respective
amounts of such Type of Revolving Credit Loan and the respective lengths of the
initial Interest Periods therefor. Each borrowing under the Revolving Credit
Commitments shall be in an amount equal to (x) in the case of Alternate Base
Rate Loans, $500,000 or a whole multiple thereof (or, if the then Available
Revolving Credit Commitments are less than $500,000, such lesser amount) and (y)
in the case of Eurodollar Loans, $1,000,000 or a whole multiple of $100,000 in
excess thereof. Upon receipt of any such notice from the Borrower, the
Administrative Agent shall promptly notify each Lender thereof. Each Lender will
make the amount of its pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the office of the
Administrative Agent specified in Section 11.2 prior to 11:00 A.M., New York
City time, on the Borrowing Date requested by the Borrower in funds immediately
available to the Administrative Agent. Such borrowing will then be made
available to the Borrower by the Administrative Agent crediting the account of
the Borrower on the books of such office with the aggregate of the amounts made
available to the Administrative Agent by the Lenders and in like funds as
received by the Administrative Agent.

                                       22
<PAGE>

         Section 2.4 Limitations on Revolving Credit Loans. No requested
Revolving Credit Loan shall be made if the sum of the Aggregate Outstanding
Revolving Credit Extensions of Credit (after giving effect to such requested
Revolving Credit Loan) would exceed the then aggregate Revolving Credit
Commitments.

         Section 2.5 Commitment Fee(a) . The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee for the
period from and including the date hereof to the Revolving Credit Termination
Date, computed at the rate per annum equal to the then Applicable Margin for the
Commitment Fee as set forth under the column heading "Applicable Margin for the
Commitment Fee" of Annex I on the average daily amount of the Available
Revolving Credit Commitment of such Lender, during the period for which payment
is made, payable quarterly in arrears on the last day of each March, June,
September and December, commencing June 30, 2001, and on the Revolving Credit
Termination Date or such earlier date as the Revolving Credit Commitments shall
terminate as provided herein, commencing on the first of such dates to occur
after the date hereof.

         Section 2.6 Termination or Reduction of Revolving Credit Commitments.

                  (a) The Borrower shall have the right, upon not less than five
Business Days' notice to the Administrative Agent, to terminate the Revolving
Credit Commitments or, from time to time, to reduce the amount of the Revolving
Credit Commitments, provided that no such termination or reduction shall be
permitted if, after giving effect thereto and to any prepayments of the
Revolving Credit Loans made on the effective date thereof, the aggregate
principal amount of the Revolving Credit Loans then outstanding, when added to
the then outstanding L/C Obligations, would exceed the Revolving Credit
Commitments then in effect. Any such reduction shall be in an amount equal to
$5,000,000 or a whole multiple thereof.

                  (b) Any reduction of Revolving Credit Commitments pursuant to
subsection 2.6(a) above or 4.1(b) shall reduce permanently the Revolving Credit
Commitments then in effect.

         Section 2.7 Extensions of Revolving Credit Termination Date. The
Borrower may, by irrevocable written notice to the Administrative Agent received
no later than 120 days prior to the Revolving Credit Termination Date then in
effect, request the Lenders to extend such Revolving Credit Termination Date to
the date 364 days following such then scheduled Revolving Credit Termination
Date. Upon receipt of any such notice, the Administrative Agent shall promptly
notify each Lender thereof. Each Lender may consent or refuse to consent to such
change, in its sole discretion, at any time on or prior to the date which is 60
days prior to the Revolving Credit Termination Date then in effect. Upon the
receipt by the Administrative Agent of the written consent of each of the
Lenders to such change in the Revolving Credit Termination Date on or prior to
2:00 p.m., New York time, on the date which is 60 days prior to the Revolving
Credit Termination Date then in effect, the Revolving Credit Termination Date
shall be changed to such subsequent date 364 days following the Revolving Credit
Termination Date then in effect, and the term "Revolving Credit Termination
Date" for all purposes of this Agreement and the other Loan Documents shall
thereupon be deemed to refer to such subsequent date. Any failure of a Lender to
provide any such consent shall be deemed to be a refusal to consent to such
change.

                                LETTERS OF CREDIT

         Section 3.1 Issuance of Letters of Credit.

                  (a) Subject to the terms and conditions hereof, the Issuing
Bank, in reliance on the agreements of the other Lenders set forth in subsection
3.3(a), agrees to issue letters of credit (the "Letters of Credit") for the
account of the Borrower on any Business Day during the Revolving Credit
Commitment Period in such form as may be approved from time to time by the
Issuing Bank; provided that the Issuing Bank shall have no obligation to issue
any Letter of Credit if, after giving effect to such issuance, (1) the L/C
Obligations would exceed the L/C Commitment or (2) the Available Revolving
Credit Commitment would be less than zero or (3) the Aggregate Outstanding
Revolving Credit Extensions of Credit would exceed the then aggregate Revolving
Credit Commitments.

                  (b) Each Letter of Credit shall:

                           (i) be denominated in Dollars and shall be either (A)
a standby letter of credit issued to support obligations of the Borrower or any
Restricted Subsidiary, contingent or otherwise, in connection with the working
capital and business needs of the Borrower or such Restricted Subsidiary, as the
case may be, in the ordinary course of business, or (B) a commercial letter of
credit issued in respect of the purchase of goods or services by the Borrower or
any Restricted Subsidiary in the ordinary course of business; and

                           (ii) expire no later than the earlier of (A) one year
after the date of issuance or renewal thereof in accordance with the term of
such Letter of Credit; provided that any Letter of Credit with an expiry date
occurring one year after its issuance may be renewed for additional one-year
periods and (B) five Business Days prior to the Revolving Credit Termination
Date.

                  (c) Each Letter of Credit shall be subject to the Uniform
Customs and, to the extent not inconsistent therewith, the laws of the State of
New York.

                  (d) The Issuing Bank shall not at any time be obligated to
issue any Letter of Credit hereunder if such issuance would conflict with, or
cause the Issuing Bank or any L/C Participant to exceed any limits imposed by,
any applicable Requirement of Law.

                  (e) Letters of Credit issued under the Existing Credit
Agreement which are outstanding on the Closing Date shall be deemed to be
Letters of Credit issued under this Agreement on the Closing Date.

         Section 3.2 Procedure for Issuance of Letters of Credit. The Borrower
may from time to time request that the Issuing Bank issue a Letter of Credit by
delivering to the Issuing Bank at its address for notices specified herein an
Application therefor, completed to the satisfaction of the Issuing Bank, and
such other certificates, documents and other papers and information as the
Issuing Bank may reasonably request. Upon receipt of any Application, the
Issuing Bank will process such Application and the certificates, documents and
other papers and information delivered to it in connection therewith in
accordance with its customary procedures and shall

                                       24
<PAGE>

promptly issue the Letter of Credit requested thereby (but in no event shall the
Issuing Bank be required to issue any Letter of Credit earlier than three
Business Days after its receipt of the Application therefor and all such other
certificates, documents and other papers and information relating thereto) by
issuing the original of such Letter of Credit to the beneficiary thereof or as
otherwise may be agreed by the Issuing Bank and the Borrower. The Issuing Bank
shall furnish a copy of such Letter of Credit to the Borrower promptly following
the issuance thereof.

         Section 3.3 Participations and Payments in Respect of the Letters of
Credit.

                  (a) The Issuing Bank irrevocably agrees to grant and hereby
grants to each L/C Participant, and, to induce the Issuing Bank to issue Letters
of Credit hereunder, each L/C Participant irrevocably agrees to accept and
purchase and hereby accepts and purchases from the Issuing Bank, on the terms
and conditions hereinafter stated, for such L/C Participant's own account and
risk an undivided interest equal to such L/C Participant's L/C Commitment
Percentage in the Issuing Bank's obligations and rights under each Letter of
Credit issued hereunder and the amount of each draft paid by the Issuing Bank
thereunder.

                  (b) Each L/C Participant unconditionally and irrevocably
agrees with the Issuing Bank that, if a draft is paid under any Letter of Credit
for which the Issuing Bank is not reimbursed on the day of such payment in full
by the Borrower in immediately available funds, such Lender shall pay to the
Issuing Bank upon demand at the Issuing Bank's address for notices specified
herein an amount equal to such L/C Participant's L/C Commitment Percentage of
the amount of such draft, or any part thereof, which is not so reimbursed. Each
L/C Participant's obligation to make each such payment to the Issuing Bank, and
the Issuing Bank's right to receive the same, are absolute and unconditional and
shall not be affected by any circumstance whatsoever, including, without
limiting the effect of the foregoing, the occurrence or continuance of a Default
or Event of Default or the failure of any other L/C Participant to make any
payment under this Section 3.3, and each L/C Participant further agrees that
each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever. Each L/C Participant shall indemnify and hold harmless the
Issuing Bank from and against any and all losses, liabilities (including,
without limitation, liabilities for penalties), actions, suits, judgments,
demands, costs and expenses (including reasonable attorneys' fees) resulting
from any failure of such L/C Participant to provide, or from any delay in
providing, the Issuing Bank with such L/C Participant's L/C Commitment
Percentage of such payment in accordance with the provisions of this Section
3.3, but no L/C Participant shall be so liable for any such failure on the part
of any other L/C Participant.

                  (c) If any amount required to be paid by any L/C Participant
to the Issuing Bank pursuant to subsection 3.3(a) in respect of any unreimbursed
portion of any payment made by the Issuing Bank under any Letter of Credit is
paid to the Issuing Bank within two Business Days after the date such payment is
due, such L/C Participant shall pay to the Issuing Bank on demand an amount
equal to the product of (i) such amount, times (ii) the daily average Federal
funds rate, as quoted by the Issuing Bank, during the period from and including
the date such payment is required to the date on which such payment is
immediately available to the Issuing Bank, times (iii) a fraction the numerator
of which is the number of days that elapse during such period and the
denominator of which is 360. If any such amount required to be paid by any L/C
Participant pursuant to subsection 3.3(a) is not in fact made available to the
Issuing Bank by such

                                       25
<PAGE>

L/C Participant within two Business Days after the date such payment is due, the
Issuing Bank shall be entitled to recover from such L/C Participant, on demand,
such amount with interest thereon calculated from such due date at the rate per
annum applicable to Alternate Base Rate Loans hereunder. A certificate of the
Issuing Bank submitted to any L/C Participant with respect to any amounts owing
under this Section 3.3 shall be conclusive in the absence of manifest error.

                  (d) Whenever, at any time after the Issuing Bank has made
payment under any Letter of Credit and has received from any L/C Participant its
pro rata share of such payment in accordance with subsection 3.3(a), the Issuing
Bank receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of collateral applied thereto
by the Issuing Bank), or any payment of interest on account thereof, the Issuing
Bank will distribute to such L/C Participant its pro rata share thereof;
provided, however, that in the event that any such payment received by the
Issuing Bank shall be required to be returned by the Issuing Bank, such L/C
Participant shall return to the Issuing Bank the portion thereof previously
distributed by the Issuing Bank to it.

         Section 3.4 Fees, Commissions and Other Charges.

                  (a) The Borrower shall pay to the Administrative Agent, for
the account of the Issuing Bank, a fronting fee with respect to each Letter of
Credit for the period from and including the date of issuance thereof to but not
including the Expiry Date thereof, computed at the rate of 1/8 of 1% per annum
on the average daily amount of the undrawn and unexpired amount of such Letter
of Credit. Such fronting fee shall be payable quarterly in advance on the date
of issuance of each Letter of Credit and on the last day of each March, June,
September and December thereafter, commencing June 30, 2001. Such fee shall be
nonrefundable.

                  (b) The Borrower shall pay to the Administrative Agent, for
the account of the Issuing Bank and the L/C Participants, a letter of credit
commission with respect to each Letter of Credit for the period from and
including the date of issuance thereof to but not including the Expiry Date
thereof, computed at the rate of the then Applicable Margin for Eurodollar Loans
per annum on the average daily amount of the undrawn and unexpired amount of
such Letter of Credit. Such commission shall be payable to the L/C Participants
to be shared ratably among them in accordance with their respective L/C
Commitment Percentages. Such commission shall be payable quarterly in advance on
the date of issuance of each Letter of Credit and on the last day of each March,
June, September and December thereafter, commencing June 30, 2001. Such fee
shall be nonrefundable.

                  (c) In addition to the foregoing fees and commissions, the
Borrower shall pay or reimburse the Issuing Bank for such normal and customary
costs and expenses as are incurred or charged by the Issuing Bank in issuing,
effecting payment under, amending or otherwise administering any Letter of
Credit.

                  (d) The Administrative Agent shall, promptly following its
receipt thereof, distribute to the Issuing Bank and the L/C Participants all
fees and commissions received by the Administrative Agent for their respective
accounts pursuant to this Section 3.4.

                                       26
<PAGE>

                  (e) The fees and commissions described in the preceding
paragraphs (a) and (b) shall be based on a 360 day year. If any amounts in the
preceding paragraphs (a) and (b) shall be payable on a day that is not a Working
Day, such amount shall be extended to the next succeeding Working Day unless the
result of such extension would be to carry such amount into another calendar
month in which event such amount shall be payable on the immediately preceding
Working Day.

         Section 3.5 Reimbursement Obligation of the Borrower.

                  (a) The Borrower agrees to reimburse the Issuing Bank on each
date on which the Issuing Bank notifies the Borrower of the date and amount of a
draft presented under any Letter of Credit and paid by the Issuing Bank for the
amount of (i) such draft so paid and (ii) any taxes, fees, charges or other
costs or expenses incurred by the Issuing Bank in connection with such payment.
Each such payment shall be made to the Issuing Bank at its address for notices
specified herein in lawful money of the United States of America and in
immediately available funds.

                  (b) Unless otherwise notified by the Borrower, each drawing
under a Letter of Credit shall constitute a request by the Borrower to the
Administrative Agent for a borrowing pursuant to Section 2.3 of Revolving Credit
Loans which are Alternate Base Rate Loans in the amount of such drawing, subject
to satisfaction of the conditions set forth in Section 6.2. The Borrowing Date
with respect to such borrowing shall be the date of such drawing.

                  (c) Interest shall be payable on any and all amounts remaining
unpaid by the Borrower under this Section 3.5 from the date such amounts become
payable (whether at stated maturity, by acceleration or otherwise) until payment
in full at the rate which would be payable on any outstanding Alternate Base
Rate Loans which were then overdue.

         Section 3.6 Obligations Absolute.

                  (a) The Borrower's obligations under this Article III shall be
absolute and unconditional under any and all circumstances and irrespective of
any set-off, counterclaim or defense to payment which the Borrower may have or
have had against the Issuing Bank or any beneficiary of any Letter of Credit.

                  (b) The Borrower also agrees with the Issuing Bank that the
Issuing Bank shall not be responsible for, and the Borrower's Reimbursement
Obligations under subsection 3.5(a) shall not be affected by, among other
things, (i) the validity or genuineness of documents or of any endorsements
thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, or (ii) any dispute between or among the Borrower and any
beneficiary of any Letter of Credit or any other party to which such Letter of
Credit may be transferred or (iii) any claims whatsoever of the Borrower against
any beneficiary of any Letter of Credit or any such transferee.

                  (c) The Issuing Bank shall not be liable for any error,
omission, interruption or delay in transmission, dispatch or delivery of any
message or advice, however transmitted, in connection with any Letter of Credit,
except for errors or omissions caused by the Issuing Bank's gross negligence or
willful misconduct.

<PAGE>

                  (d) The Borrower agrees that any action taken or omitted by
the Issuing Bank under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence of willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial Code of the State of New York, shall be binding on the Borrower and
shall not result in any liability of the Issuing Bank to the Borrower.

         Section 3.7 Letter of Credit Payments. If any draft shall be presented
for payment under any Letter of Credit, the Issuing Bank shall promptly notify
the Borrower of the date and amount thereof. The responsibility of the Issuing
Bank to the Borrower in connection with any draft presented for payment under
any Letter of Credit shall, in addition to any payment obligation expressly
provided for in such Letter of Credit, be limited to determining that the
documents (including each draft) delivered under such Letter of Credit in
connection with such presentment are in conformity with such Letter of Credit.

         Section 3.8 Applications. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Article III, the provisions of this Article III shall apply.

                                   ARTICLE IV
                          GENERAL PROVISIONS FOR LOANS

         Section 4.1 Optional and Mandatory Prepayments.

                  (a) The Borrower may on the last day of any Interest Period
with respect thereto, in the case of Eurodollar Loans, or at any time and from
time to time, in the case of Alternate Base Rate Loans, prepay the Revolving
Credit Loans, in whole or in part, without premium or penalty, upon at least
four Business Days' irrevocable notice to the Administrative Agent, specifying
the date and amount of prepayment and whether the prepayment is of Eurodollar
Loans, Alternate Base Rate Loans or a combination thereof, and, if of a
combination thereof, the amount allocable to each. Upon receipt of any such
notice the Administrative Agent shall promptly notify each Lender thereof. If
any such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein. Partial prepayments shall be in an
aggregate principal amount of $1,000,000 or a whole multiple thereof.

                  (b) If on any date (including any date on which a certificate
of a Responsible Officer of the Borrower is delivered pursuant to subsection
7.2(b)) the sum of the Aggregate Outstanding Revolving Credit Extensions of
Credit then outstanding exceeds the then aggregate Revolving Credit Commitments,
then, without notice or demand, the Borrower shall promptly prepay the Revolving
Credit Loans in an amount equal to such excess. The Borrower may, subject to the
terms and conditions of this Agreement, reborrow the amount of any prepayment
made under subsection 4.1(c).

                  (c) The application of any prepayment pursuant to subsection
4.1(b) shall be made first to Alternate Base Rate Loans and second to Eurodollar
Loans. Each prepayment of the Loans under subsection 4.1(b) (other than
Alternate Base Rate Loans) shall be accompanied by accrued interest to the date
of such prepayment on the amount prepaid.

         Section 4.2 Conversion and Continuation Options.

                                       28
<PAGE>

                  (a) The Borrower may elect from time to time to convert
Eurodollar Loans to Alternate Base Rate Loans by giving the Administrative Agent
at least two Business Days' prior irrevocable notice of such election, provided
that any such conversion of Eurodollar Loans may only be made on the last day of
an Interest Period with respect thereto. The Borrower may elect from time to
time to convert Alternate Base Rate Loans to Eurodollar Loans by giving the
Administrative Agent at least three Working Days' prior irrevocable notice of
such election. Any such notice of conversion to Eurodollar Loans shall specify
the length of the initial Interest Period or Interest Periods therefor. Upon
receipt of any such notice the Administrative Agent shall promptly notify each
Lender thereof. All or any part of outstanding Eurodollar Loans and Alternate
Base Rate Loans may be converted as provided herein, provided that (i) no
Revolving Credit Loan may be converted into a Eurodollar Loan when any Default
or Event of Default has occurred and is continuing and the Administrative Agent
has or the Required Lenders have determined that such a conversion is not
appropriate, (ii) any such conversion may only be made if, after giving effect
thereto, Section 4.3 shall not have been contravened and (iii) no Revolving
Credit Loan may be converted into a Eurodollar Loan after the date that is one
month prior to the Revolving Credit Termination Date.

                  (b) Any Eurodollar Loans may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Revolving Credit
Loans, provided that no Eurodollar Loan may be continued as such (i) when any
Default or Event of Default has occurred and is continuing and the
Administrative Agent has or the Required Lenders have determined that such a
continuation is not appropriate, (ii) if, after giving effect thereto, Section
4.3 would be contravened or (iii) after the date that is one month prior to the
Revolving Credit Termination Date and provided, further, that if the Borrower
shall fail to give any required notice as described above in this paragraph or
if such continuation is not permitted pursuant to the preceding proviso such
Revolving Credit Loans shall be automatically converted to Alternate Base Rate
Loans on the last day of such then expiring Interest Period.

         Section 4.3 Minimum Amounts of Tranches. All borrowings, conversions
and continuations of Revolving Credit Loans hereunder and all selections of
Interest Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, (a) the aggregate principal
amount of the Revolving Credit Loans comprising each Tranche shall be equal to
$2,000,000 or a whole multiple of $100,000 in excess thereof, and (b) the number
of Tranches then outstanding shall not exceed eight.

         Section 4.4 Interest Rates and Payment Dates.

                  (a) Each Eurodollar Loan shall bear interest for each day
during each Interest Period with respect thereto at a rate per annum equal to
the Eurodollar Rate determined for such day plus the Applicable Margin.

                  (b) Each Alternate Base Rate Loan shall bear interest at a
rate per annum equal to the Alternate Base Rate plus the Applicable Margin.

                                       29
<PAGE>

                  (c) If all or a portion of (i) the principal amount of any
Revolving Credit Loan, (ii) any interest payable thereon or (iii) any commitment
fee or other amount payable hereunder shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), such overdue amount shall bear
interest at a rate per annum which is the higher of (A) the rate that would
otherwise be applicable thereto pursuant to the foregoing provisions of this
Section 4.4 plus 2% and (B) the Alternate Base Rate plus 1%, in each case from
the date of such non-payment until such amount is paid in full (as well after as
before judgment).

                  (d) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (c) of this
Section 4.4 shall be payable from time to time on demand.

         Section 4.5 Computation of Interest and Fees.

                  (a) Interest on Alternate Base Rate Loans, commitment fees and
interest on overdue interest, commitment fees and other amounts payable
hereunder shall be calculated on the basis of a 365- (or 366-, as the case may
be) day year for the actual days elapsed. Interest on Eurodollar Loans shall be
calculated on the basis of a 360-day year for the actual days elapsed. The
Administrative Agent shall as soon as practicable notify the Borrower and the
Lenders of each determination of a Eurodollar Rate. Any change in the interest
rate on a Loan resulting from a change in the Alternate Base Rate or the
Eurocurrency Reserve Requirements shall become effective as of the opening of
business on the day on which such change becomes effective. The Administrative
Agent shall as soon as practicable notify the Borrower and the Lenders of the
effective date and the amount of each such change in interest rate.

                  (b) Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to subsection
4.4(a).

         Section 4.6 Inability to Determine Interest Rate. If prior to the first
day of any Interest Period:

                  (a) the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the Eurodollar Rate for such Interest Period, or

                  (b) the Administrative Agent shall have received notice from
the Required Lenders that the Eurodollar Rate determined or to be determined for
such Interest Period will not adequately and fairly reflect the cost to such
Lenders (as conclusively certified by such Lenders) of making or maintaining
their affected Revolving Credit Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter. If such notice is
given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as Alternate Base Rate Loans, (y) any Revolving
Credit Loans that were to have been converted on the first day of

                                       30
<PAGE>

such Interest Period to Eurodollar Loans shall be converted to or continued as
Alternate Base Rate Loans and (z) any outstanding Eurodollar Loans shall be
converted, on the first day of such Interest Period, to Alternate Base Rate
Loans. Until such notice has been withdrawn by the Administrative Agent, no
further Eurodollar Loans shall be made or continued as such, nor shall the
Borrower have the right to convert Revolving Credit Loans to Eurodollar Loans.

         Section 4.7 Pro Rata Treatment and Payments.

                  (a) Each borrowing by the Borrower from the Lenders hereunder,
each payment by the Borrower on account of any commitment fee hereunder and any
reduction of the Revolving Credit Commitments of the Lenders shall be made pro
rata according to the respective Commitment Percentages of the Lenders. Each
payment (including each prepayment) by the Borrower on account of principal of
and interest on the Revolving Credit Loans shall be made pro rata according to
the respective outstanding principal amounts of the Revolving Credit Loans then
held by the Lenders. All payments (including prepayments) to be made by the
Borrower hereunder and under the Revolving Credit Notes, whether on account of
principal, interest, fees or otherwise, shall be made without set off or
counterclaim and shall be made prior to 12:00 Noon, New York City time, on the
due date thereof to the Administrative Agent, for the account of the Lenders, at
the Administrative Agent's office specified in Section 11.2, in Dollars and in
immediately available funds. The Administrative Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension and with respect to payments of fees, such fees accruing during such
extension shall be payable on the next succeeding Business Day. If any payment
on a Eurodollar Loan becomes due and payable on a day other than a Working Day,
the maturity thereof shall be extended to the next succeeding Working Day unless
the result of such extension would be to extend such payment into another
calendar month, in which event such payment shall be made on the immediately
preceding Working Day.

                  (b) Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a Borrowing Date that such Lender will not
make the amount that would constitute its Commitment Percentage of the borrowing
on such date available to the Administrative Agent, the Administrative Agent may
assume that such Lender has made such amount available to the Administrative
Agent on such Borrowing Date, and the Administrative Agent may, in reliance upon
such assumption, make available to the Borrower a corresponding amount. If such
amount is made available to the Administrative Agent on a date after such
Borrowing Date, such Lender shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal Funds Effective
Rate during such period, times (ii) the amount of such Lender's Commitment
Percentage of such borrowing, times (iii) a fraction the numerator of which is
the number of days that elapse from and including such Borrowing Date to the
date on which such Lender's Commitment Percentage of such borrowing shall have
become immediately available to the Administrative Agent and the denominator of
which is 360. A certificate of the Administrative Agent submitted to any Lender
with respect to any amounts owing under this Section 4.7 shall be conclusive in
the absence of manifest error. If such Lender's Commitment Percentage of such
borrowing is not in fact made available to the

                                       31
<PAGE>

Administrative Agent by such Lender within three Business Days of such Borrowing
Date, the Administrative Agent shall be entitled to recover such amount with
interest thereon at the rate per annum applicable to Alternate Base Rate Loans
hereunder, on demand, from the Borrower.

         Section 4.8 Illegality. Notwithstanding any other provision herein, if
the adoption of or any change in any Requirement of Law or in the interpretation
or application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Alternate Base Rate Loans to Eurodollar Loans shall forthwith be
cancelled and (b) such Lender's Revolving Credit Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to Alternate Base
Rate Loans on the respective last days of the then current Interest Periods with
respect to such Revolving Credit Loans or within such earlier period as required
by law. If any such conversion of a Eurodollar Loan occurs on a day which is not
the last day of the then current Interest Period with respect thereto, the
Borrower shall pay to such Lender such amounts, if any, as may be required
pursuant to Section 4.11.

         Section 4.9 Requirements of Law.

                  (a) If the adoption of or any change in any Requirement of Law
or in the interpretation or application thereof or compliance by any Lender with
any request or directive (whether or not having the force of law) from any
central bank or other Governmental Authority made subsequent to the date hereof:

                           (i) shall subject any Lender to any tax of any kind
whatsoever with respect to this Agreement, any Revolving Credit Note, any Letter
of Credit, any Application or any Eurodollar Loan made by it, or change the
basis of taxation of payments to such Lender in respect thereof (except for
taxes covered by Section 4.10 and changes in the rate of tax on the overall net
income of such Lender);

                           (ii) shall impose, modify or hold applicable any
reserve, special deposit, compulsory loan or similar requirement against assets
held by, deposits or other liabilities in or for the account of, advances, loans
or other extensions of credit by, or any other acquisition of funds by, any
office of such Lender which is not otherwise included in the determination of
the Eurodollar Rate hereunder; or

                           (iii) shall impose on such Lender any other
condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in the
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Lender,
upon its demand, any additional amounts necessary to compensate such Lender for
such increased cost or reduced amount receivable. If any Lender becomes entitled
to claim any additional amounts pursuant to this Section 4.9, it shall promptly
notify the Borrower, through the Administrative Agent, of the event by reason of
which it has become so entitled. A certificate as to any additional amounts
payable pursuant to this Section 4.9 submitted by such

                                       32
<PAGE>

Lender, through the Administrative Agent, to the Borrower shall be conclusive in
the absence of manifest error. This covenant shall survive the termination of
this Agreement and the payment of the Revolving Credit Notes and all other
amounts payable hereunder.

                  (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof does or shall have the effect of
reducing the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Lender or such corporation could have achieved but
for such change or compliance (taking into consideration such Lender's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
such Lender to be material, then from time to time, after submission by such
Lender to the Borrower (with a copy to the Administrative Agent) of a written
request therefor, the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender for such reduction.

         Section 4.10 Taxes.

                  (a) All payments made by the Borrower under this Agreement and
the Revolving Credit Notes shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future income,
stamp or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any Governmental Authority, excluding, in the case of the Administrative
Agent and each Lender, net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on the Administrative Agent or such Lender, as the
case may be, as a result of a present or former connection between the
jurisdiction of the government or taxing authority imposing such tax and the
Administrative Agent or such Lender (excluding a connection arising solely from
the Administrative Agent or such Lender having executed, delivered or performed
its obligations or received a payment under, or enforced, this Agreement or the
Revolving Credit Notes) or any political subdivision or taxing authority thereof
or therein (all such non-excluded taxes, levies, imposts, duties, charges, fees,
deductions and withholdings being hereinafter called "Taxes"). If any Taxes are
required to be withheld from any amounts payable to the Administrative Agent or
any Lender hereunder or under the Revolving Credit Notes, the amounts so payable
to the Administrative Agent or such Lender shall be increased to the extent
necessary to yield to the Administrative Agent or such Lender (after payment of
all Taxes) interest or any such other amounts payable hereunder at the rates or
in the amounts specified in this Agreement and the Revolving Credit Notes.
Whenever any Taxes are payable by the Borrower, as promptly as possible
thereafter the Borrower shall send to the Administrative Agent for its own
account or for the account of such Lender, as the case may be, a certified copy
of an original official receipt received by the Borrower showing payment
thereof. If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Administrative Agent the required
receipts or other required documentary evidence, the Borrower shall indemnify
the Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure. The

                                       33
<PAGE>

agreements in this Section 4.10 shall survive the termination of this Agreement
and the payment of the Revolving Credit Notes and all other amounts payable
hereunder.

                  (b) Each Lender that is not incorporated under the laws of the
United States of America or a state thereof shall:

                           (i) deliver to the Borrower and the Administrative
Agent (A) two duly completed copies of United States Internal Revenue Service
Form W8-ECI or W8-BEN, or successor applicable form, as the case may be, and (B)
an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as
the case may be;

                           (ii) deliver to the Borrower and the Administrative
Agent two further copies of any such form or certification on or before the date
that any such form or certification expires or becomes obsolete and after the
occurrence of any event requiring a change in the most recent form previously
delivered by it to the Borrower; and

                           (iii) obtain such extensions of time for filing and
complete such forms or certifications as may reasonably be requested by the
Borrower or the Administrative Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Borrower and the
Administrative Agent. Such Lender shall certify (i) in the case of a Form W8-ECI
or W8-BEN, that it is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes and (ii) in
the case of a Form W-8 or W-9, that it is entitled to an exemption from United
States backup withholding tax. Each Person that shall become a Lender or a
Participant pursuant to Section 11.6 shall, upon the effectiveness of the
related transfer, be required to provide all of the forms and statements
required pursuant to this Section 4.10, provided that in the case of a
Participant such Participant shall furnish all such required forms and
statements to the Lender from which the related participation shall have been
purchased.

         Section 4.11 Indemnity. The Borrower agrees to indemnify each Lender
and to hold each Lender harmless from any loss or expense which such Lender may
sustain or incur as a consequence of (a) default by the Borrower in payment when
due of the principal amount of or interest on any Eurodollar Loan, (b) default
by the Borrower in making a borrowing of, conversion into or continuation of
Eurodollar Loans after the Borrower has given a notice requesting the same in
accordance with the provisions of this Agreement, (c) default by the Borrower in
making any prepayment after the Borrower has given a notice thereof in
accordance with the provisions of this Agreement or (d) the making of a
prepayment of Eurodollar Loans on a day which is not the last day of an Interest
Period with respect thereto, including, without limitation, in each case, any
such loss or expense arising from the reemployment of funds obtained by it or
from fees payable to terminate the deposits from which such funds were obtained.
This covenant shall survive the termination of this Agreement and the payment of
the Revolving Credit Notes and all other amounts payable hereunder.

         Section 4.12 Lenders Obligation to Mitigate. Each Lender agrees that,
as promptly as practicable after it becomes aware that it has been or will be
affected by the occurrence of an event or the existence of a condition described
under Section 4.8 or subsection 4.9(a) or 4.10(a), it will, to the extent not
inconsistent with such Lender's internal policies, use its best efforts (a) to
provide written notice to the Borrower describing such condition and the
anticipated effect thereof and (b) to make, fund or maintain the affected
Eurodollar Loans of such Lender through another lending office of such Lender if
as a result thereof the additional moneys which would otherwise be required to
be paid in respect of such Revolving Credit Loans pursuant to Section 4.8 or
subsection 4.9(a) or 4.10(a) would be materially reduced or the illegality or
other adverse circumstances which would otherwise require such payment pursuant
to Section 4.8 or subsection 4.9(a) or 4.10(a) would cease to exist and if, as
determined by such Lender, in its sole discretion, the making, funding or
maintaining of such Revolving Credit Loans through such other lending office
would not otherwise adversely affect such Revolving Credit Loans or such Lender.
The Borrower hereby agrees to pay all reasonable expenses incurred by any Lender
in utilizing another lending office of such Lender pursuant to this Section
4.12.

         Section 4.13 Certain Permitted Transactions. Notwithstanding any
provision in the Loan Documents and without increasing the obligations of the
Lenders under Articles II and III of this Agreement, EPEPC, the Borrower and its
Subsidiaries shall have the right to consummate any of the following
transactions:

guarantee shall not exceed $140,000,000.

                  (b) Argo Financing Transactions.

                           (i) the contribution by the Borrower and the

                           (ii) the pledge by the Borrower and the Restricted

                           (iii) the incurrence by the Borrower and the
Restricted Subsidiaries of the Argo Clawback, and the securing of the Argo
Clawback obligations by the Collateral on a pari passu basis with the
Obligations, subject to the Intercreditor Agreement.

                  (c) Contribution of Non-Managing Interest. The contribution by
EPEPC to the Borrower of EPEPC's approximately one percent non-managing interest

         Section 4.14 Acquisition; Disposition; Redesignation. If the Borrower
         or any of its Restricted Subsidiaries acquires any Acquired Business or
         makes any sale or disposition of any assets or property having a value
         in excess of $20,000,000 pursuant to subsection 8.6(b) or 8.6(e) or
         there is a Redesignation of any Subsidiary during any Calculation
         Period, Consolidated EBITDA, Consolidated Tangible Net Worth,
         Consolidated Interest Expense, Consolidated Total Senior Indebtedness
         and Consolidated Total Indebtedness for such Calculation Period will be
         determined on a pro forma basis as if such Acquired Business were
         acquired, such assets or property was sold or disposed of or such
         Redesignation occurred, on the first day thereof. Such pro forma
         adjustments will be subject to delivery to the Administrative Agent of
         a certificate of a Responsible Officer of the Borrower. Such
         certificate may be delivered at any time with respect to any
         Redesignation and at any time after the last day of the first fiscal
         quarter of the Borrower to end after the related acquisition date with
         respect to any Acquired Business or the related disposition date with
         respect to any such sale or disposition. Each such certificate shall be
         accompanied by supporting information and calculations with respect to
         each such Acquired Business, sale or disposition or Redesignation and
         such other information as any Lender, through the Administrative Agent,
         may reasonably request. For purposes of determining satisfaction of
         Section 6.2(d), effect shall be given on the date of determination to
         pro forma adjustments as described in this Section 4.14 with respect to
         any Acquired Business that has been acquired as of such date.

         Section 4.15 Redesignated Senior Indebtedness. The Borrower and the
Co-Borrower hereby designate all Obligations of the Borrower and its
Subsidiaries (including the Co-Borrower) under this Agreement and the other Loan
Documents as Designated Senior Debt, as such term is defined in the Senior
Subordinated Note Indentures.

                                    ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

         To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make the Revolving Credit Loans and issue or participate in the
Letters of Credit, the Borrower hereby represents and warrants to the

Subsidiary Guarantor in accordance with its terms, except as enforceability may
be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by

creation or imposition of any Lien on any of their respective properties or
revenues pursuant to any such Requirement of Law or Contractual Obligation.

         Section 5.6 No Material Litigation. Except as set forth on Schedule
5.6, no litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the knowledge of the Borrower,
threatened by or against the Borrower or any of its Subsidiaries, or, to the
best knowledge of the Borrower, any Joint Venture any of the interests in which

hereby or thereby, or (b) which could reasonably be expected to have a Material
Adverse Effect.

title to, or a valid leasehold interest in, all its other property, and none of
such property necessary for its operations as then conducted is subject to any
Lien except as permitted by Section 8.3.

Restricted Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not have a Material Adverse Effect (the "Intellectual Property"). No
claim has been asserted 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 the Borrower know of any valid basis
for any such claim. The use of such Intellectual Property by the Borrower and
its Restricted Subsidiaries does not infringe on the rights of any Person,
except for such claims and infringements that, in the aggregate, do not have a
Material Adverse Effect.

         Section 5.10 No Burdensome Restrictions. The Borrower, in good faith,

Note Indentures, or any Loan Party, any Affiliate of any Loan Party, the trustee
in respect of the Senior Subordinated Notes or the holders of at least 25% in
aggregate principal amount of a series of such Senior Subordinated Notes shall
so assert;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Revolving Credit Commitments shall immediately terminate and
the Revolving Credit Loans hereunder (with accrued interest thereon) and all
other amounts owing under this Agreement (including, without limitation, all
amounts of L/C Obligations, whether or not the beneficiaries of the then
outstanding Letters of Credit shall have presented the documents required
thereunder) and the Revolving Credit Notes shall immediately become due and

the following actions may be taken: (i) with the consent of the Required
Lenders, the Administrative Agent may, or upon the request of the Required
Lenders, the Administrative Agent shall, by notice to the Borrower declare the
Revolving Credit Commitments to be terminated forthwith, whereupon the Revolving
Credit Commitments shall

                                       67
<PAGE>
immediately terminate; and (ii) with the consent of the Required Lenders, the
Administrative Agent may, or upon the request of the Required Lenders, the
Administrative Agent shall, by notice to the Borrower, declare the Revolving
Credit Loans hereunder (with accrued interest thereon) and all other amounts
owing under this Agreement (including, without limitation, all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) and the Revolving
Credit Notes to be due and payable forthwith, whereupon the same shall
immediately become due and payable. If presentment for honor under any Letter of
Credit shall not have occurred at the time of an acceleration pursuant to the
preceding sentence, the Borrower shall at such time deposit in a cash collateral
account opened by the Administrative Agent an amount equal to the aggregate then
undrawn and unexpired amount of the Letters of Credit. The Borrower hereby
grants to the Administrative Agent, for the benefit of the Issuing Bank and the
Lenders, a security interest in such cash collateral to secure all obligations
of the Borrower under this Agreement and the other Loan Documents. Amounts held
in such cash collateral account shall be applied by the Administrative Agent to
the payment of drafts drawn under such Letters of Credit, and the unused portion
thereof after all such Letters of Credit shall have expired or been fully drawn
upon, if any, shall be applied to repay other obligations of the Borrower
hereunder and under the Revolving Credit Notes. After all such Letters of Credit
shall have expired or been fully drawn upon, all Reimbursement Obligations shall
have been satisfied and all other obligations of the Borrower hereunder and
under the Revolving Credit Notes shall have been paid in full, the balance, if
any, in such cash collateral account shall be returned to the Borrower. The
Borrower shall execute and deliver to the Administrative Agent, for the account
of the Issuing Bank and the Lenders, such further documents and instruments as
the Administrative Agent may request to evidence the creation and perfection of
the within security interest in such cash collateral account. Except as
expressly provided above in this Section, presentment, demand, protest, notice
of intent to accelerate, notice of acceleration and all other notices of any
kind are hereby expressly waived.

                            THE ADMINISTRATIVE AGENT

         Section 10.1 Appointment. Each Lender hereby irrevocably designates and
appoints The Chase Manhattan Bank as the Administrative Agent of such Lender
under this Agreement and the other Loan Documents, and each such Lender
irrevocably authorizes The Chase Manhattan Bank, as the Administrative Agent for
such Lender, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Administrative Agent by the terms
of this Agreement and the other Loan Documents, together with such other powers
as are reasonably incidental thereto. Notwithstanding any provision to the
contrary elsewhere in this Agreement, the Administrative Agent shall not have
any duties or responsibilities, except those expressly set forth herein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

         Section 10.2 Delegation of Duties. The Administrative Agent may execute
any of its duties under this Agreement and the other Loan Documents by or
through agents or attorneys-in-

                                       68
<PAGE>
fact and shall be entitled to advice of counsel concerning all matters
pertaining to such duties. The Administrative Agent shall not be responsible for
the negligence or misconduct of any agents or attorneys in-fact selected by it
with reasonable care.

         Section 10.3 Exculpatory Provisions. Neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrower or
any officer thereof contained in this Agreement or any other Loan Document or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or the Revolving
Credit Notes or any other Loan Document or for any failure of the Borrower to
perform its obligations hereunder or thereunder. The Administrative Agent shall
not be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Borrower.

         Section 10.4 Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
Revolving Credit Note, writing, resolution, notice, consent, certificate,
affidavit, letter, telecopy, telex or teletype message, statement, order or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Borrower), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Revolving Credit Note as the owner thereof for all purposes unless a written
notice of assignment, negotiation or transfer thereof shall have been filed with
the Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the Revolving Credit Notes and
the other Loan Documents in accordance with a request of the Required Lenders,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all the Lenders and all future holders of the Revolving Credit
Notes.

         Section 10.5 Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent has received notice from a
Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". In the
event that the Administrative Agent receives such a notice, the Administrative
Agent shall give notice thereof to the Lenders. The Administrative Agent shall
take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required

                                       69
<PAGE>
Lenders; provided that unless and until the Administrative Agent shall have
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interests of the Lenders.

         Section 10.6 Non-Reliance on Administrative Agent and Other Lenders.
Each Lender expressly acknowledges that neither the Administrative Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates
has made any representations or warranties to it and that no act by the
Administrative Agent hereafter taken, including any review of the affairs of the
Borrower, shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of the Borrower and made its own decision to make its Loans
hereunder and enter into this Agreement. Each Lender also represents that it
will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Borrower which may come into
the possession of the Administrative Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates.

         Section 10.7 Indemnification. The Lenders agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought under this Section, from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever which
may at any time (including, without limitation, at any time following the
payment of the Revolving Credit Notes) be imposed on, incurred by or asserted
against the Administrative Agent in any way relating to or arising out of this
Agreement, any of the other Loan Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by the Administrative Agent under or in
connection with any of the foregoing; provided that no Lender shall be liable
for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Administrative Agent's gross negligence or willful
misconduct. The agreements in this Section 10.7 shall survive the payment of the
Revolving Credit Notes and all other amounts payable hereunder.

         Section 10.8 Administrative Agent in Its Individual Capacity. The
Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any

                                       70
<PAGE>
kind of business with the Borrower as though the Administrative Agent were not
the Administrative Agent hereunder and under the other Loan Documents. With
respect to its Loans made or renewed by it and any Revolving Credit Note issued
to it and with respect to the Letters of Credit, the Administrative Agent shall
have the same rights and powers under this Agreement and the other Loan
Documents as any Lender and may exercise the same as though it were not the
Administrative Agent. The terms "Lender" and "Lenders" shall include the
Administrative Agent in its individual capacity.

         Section 10.9 Successor Administrative Agent. The Administrative Agent
may resign as Administrative Agent upon 10 days' written notice to the Lenders.
If the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor agent
shall be approved by the Borrower, whereupon such successor agent shall succeed
to the rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Revolving Credit Notes.
After any retiring Administrative Agent's resignation as Administrative Agent,
the provisions of this Section shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Loan Documents.

         Section 10.10 Other Agents. None of the Lenders identified on the cover
page or the preamble of this Agreement as a "co-syndication agent" or a
"co-documentation agent" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of the Lenders so
identified as a "co-syndication agent" or a "co-documentation agent" shall have
or be deemed to have any fiduciary relationship with any Lender. Each Lender
acknowledges that it has not relied, and will not rely, on any of the Lenders so
identified in deciding to enter into this Agreement or in taking or not taking
any action hereunder.

                                   ARTICLE XI
                                  MISCELLANEOUS

         Section 11.1 Amendments and Waivers. Neither this Agreement, any
Revolving Credit Note, any other Loan Document, nor any terms hereof or thereof
may be amended, supplemented or modified except in accordance with the
provisions of this Section 11.1. The Required Lenders may, or, with the written
consent of the Required Lenders, the Administrative Agent may, from time to
time, (a) enter into with the Borrower or the Loan party thereto written
amendments, supplements or modifications hereto and to the Revolving Credit
Notes and the other Loan Documents for the purpose of adding any provisions to
this Agreement or the Revolving Credit Notes or the other Loan Documents or
changing in any manner the rights of the Lenders or of the Borrower or any other
Loan Party hereunder or thereunder or (b) waive in writing, on such terms and
conditions as the Required Lenders or the Administrative Agent, as the case may
be, may specify in such instrument, any of the requirements of this Agreement or
the Revolving Credit Notes or the other Loan Documents or any Default or Event
of Default and its consequences; provided, however, that no such waiver and no
such amendment, supplement or modification

shall (i) reduce the amount or extend the scheduled date of maturity of any
Revolving Credit Note or of any installment thereof, or reduce the stated rate
of any interest or fee payable hereunder or extend the scheduled date of any
payment thereof or increase the amount or extend the expiration date of any
Lender's Revolving Credit Commitment, in each case without the consent of each
Lender affected thereby, or (ii) amend, modify or waive any provision of this
Section 11.1 or reduce the percentage specified in the definition of Required
Lenders, or consent to the assignment or transfer by the Borrower of any of its
rights and obligations under this Agreement and the other Loan Documents (except
in a transaction permitted by Section 8.5), in each case without the written
consent of all the Lenders, or (iii) amend, modify or waive any provision of
Article X without the written consent of the then Administrative Agent, (iv)
release the Lenders' Liens on all or substantially all of the Collateral under
the Security Documents without the consent of each Lender or (v) except to the
extent relating to the Redesignation of any Restricted Subsidiary, the sale or
other disposition of any Restricted Subsidiary as otherwise permitted by this
Agreement or any other transaction permitted by this Agreement, release any
Guarantee. Any such waiver and any such amendment, supplement or modification
shall apply equally to each of the Lenders and shall be binding upon the
Borrower, the Lenders, the Administrative Agent and all future holders of the
Revolving Credit Notes. In the case of any waiver, the Borrower, the Lenders and
the Administrative Agent shall be restored to their former position and rights
hereunder and under the outstanding Revolving Credit Notes and any other Loan
Documents, and any Default or Event of Default waived shall be deemed to be
cured and not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default, or impair any right consequent thereon.

pay or reimburse the Administrative Agent for all its reasonable out-of-pocket
costs and expenses incurred in connection with the development, preparation and
execution of, and any amendment, supplement or modification to, this Agreement
and the Revolving Credit Notes and the other Loan Documents and any other

administration of the transactions contemplated hereby and thereby, including,
without limitation, the fees and disbursements of counsel to the Administrative
Agent, (b) to pay or reimburse each Lender and the Administrative Agent for all
its costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, the Revolving Credit Notes, the
other Loan Documents and any such other documents, including, without
limitation, the fees and disbursements of counsel to the Administrative Agent
and to the several Lenders, (c) to pay, indemnify, and hold each Lender and the
Administrative Agent harmless from, any and all recording and filing fees and
any and all liabilities with respect to, or resulting from any delay in paying,
stamp, excise and other taxes, if any, which may be payable or determined to be
payable in connection with the execution and delivery of, or consummation or

this Agreement, the Revolving Credit Notes, the other Loan Documents and any
such other documents, and (d) to pay, indemnify, and hold each Lender, the
Administrative Agent, the Co-Syndication Agents, the Co-Documentation Agents,

harmless from and against any and all other liabilities, obligations, losses,
damages, penalties, actions, judgments and suits, and reasonable costs, expenses
or disbursements, of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement, the Revolving Credit Notes and the other Loan Documents, the use of
the proceeds

                                       73
<PAGE>
of the Revolving Credit Loans, including the use and reliance on electronic,
telecommunications or other information or transmission systems in connection
with the Loan Documents (all the foregoing in this clause (d), collectively, the
"indemnified liabilities"), REGARDLESS OF WHETHER OR NOT SUCH INDEMNIFIED
LIABILITIES ARE IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AN INDEMNIFIED PARTY, provided, that
the Borrower shall have no obligation hereunder to an Indemnified Party with
respect to indemnified liabilities arising from (i) the gross negligence or
willful misconduct of such Indemnified Party or (ii) legal proceedings commenced
against an Indemnified Party by any security holder or creditor thereof arising
out of and based upon rights afforded any such security holder or creditor
solely in its capacity as such. The agreements in this Section shall survive
repayment of the Revolving Credit Notes and all other amounts payable hereunder.

         Section 11.6 Successors and Assigns; Participations; Purchasing
Lenders.

                  (a) This Agreement shall be binding upon and inure to the
benefit of the Borrower, the Lenders, the Administrative Agent, all future
holders of the Revolving Credit Notes and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
or obligations under this Agreement without the prior written consent of each
Lender.

                  (b) Any Lender may, in the ordinary course of its commercial
banking business and in accordance with applicable law, and after notice to the
Borrower, at any time sell to one or more banks or other entities
("Participants") participating interests in any Revolving Credit Loan owing to
such Lender, any Revolving Credit Note held by such Lender, any Revolving Credit
Commitment of such Lender or any other interest of such Lender hereunder and
under the other Loan Documents. In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof, such Lender
shall remain the holder of any such Revolving Credit Note for all purposes under
this Agreement and the other Loan Documents, and the Borrower and the
Administrative Agent shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under this Agreement and
the other Loan Documents. The Borrower agrees that if amounts outstanding under
this Agreement and the Revolving Credit Notes are due or unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each Participant shall be deemed to have the right of setoff
in respect of its participating interest in amounts owing under this Agreement
and any Revolving Credit Note to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement or any Revolving Credit Note, provided that, in purchasing such
participating interest, such Participant shall be deemed to have agreed to share
with the Lenders the proceeds thereof as provided in subsection 11.7(a) as fully
as if it were a Lender hereunder. The Borrower also agrees that each Participant
shall be entitled to the benefits of Sections 4.9, 4.10 and 4.11 with respect to
its participation in the Revolving Credit Commitments, the Revolving Credit
Loans and the Letters of Credit outstanding from time to time; provided, that no
Participant shall be entitled to receive any greater amount pursuant to such
Sections than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor

                                       74
<PAGE>
Lender to such Participant had no such transfer occurred. No Lender shall be
entitled to create in favor of any Participant, in the participation agreement
pursuant to which such Participant's participating interest shall be created or
otherwise, any right to vote on, consent to or approve any matter relating to
this Agreement or any other Loan Document except for those specified in clauses
(i) to (v) of the proviso of subsection 11.1(b) to the extent the Participant is
directly affected thereby.

                  (c) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time sell to any Lender or any
successor or affiliate thereof and, with the consent of the Borrower and the
Administrative Agent (which in each case shall not be unreasonably withheld or,
with respect to the Borrower, shall not be required during the continuance of
any Event of Default), to one or more additional banks or financial institutions
or funds that regularly purchase loans ("Purchasing Lenders") all or any part of
its rights and obligations under this Agreement and the Revolving Credit Notes
pursuant to an Assignment and Acceptance, substantially in the form of Exhibit
M, executed by such Purchasing Lender, such transferor Lender (and, in the case
of a Purchasing Lender that is not then a Lender or an affiliate thereof, by the
Borrower and the Administrative Agent except to the extent the Borrower's
consent is not required hereunder) and delivered to the Administrative Agent for
its acceptance and recording in the Register ,provided that no such assignment
to an assignee (other than any Lender or any affiliate of any Lender) shall be
in an aggregate principal amount of less than $10,000,000 (other than in the
case of an assignment of all of a Lender's interest under this Agreement) and
the assigning Lender shall have retained at least $10,000,000 of Revolving
Credit Commitments (unless it is assigning all of its Revolving Credit
Commitments and Revolving Credit Loans), unless otherwise agreed by the Borrower
and the Administrative Agent. For purposes of the proviso contained in the
preceding sentence, the amount described therein shall be aggregated in respect
to each Lender and its related affiliates, if any. Upon such execution,
delivery, acceptance and recording, from and after the Transfer Effective Date
determined pursuant to such Assignment and Acceptance, (x) the Purchasing Lender
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Credit Commitment as set forth therein, and (y) the transferor
Lender thereunder shall, to the extent provided in such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all or the remaining portion of a
transferor Lender's rights and obligations under this Agreement, such transferor
Lender shall cease to be a party hereto but shall continue to be entitled to the
benefit of the indemnity and expense reimbursement provisions of the Loan
Documents to the extent relating to matters during the time it was a Lender).
Such Assignment and Acceptance shall be deemed to amend this Agreement to the
extent, and only to the extent, necessary to reflect the addition of such
Purchasing Lender and the resulting adjustment of Commitment Percentages arising
from the purchase by such Purchasing Lender of all or a portion of the rights
and obligations of such transferor Lender under this Agreement and the Revolving
Credit Notes. On or prior to the Transfer Effective Date determined pursuant to
such Assignment and Acceptance, the Borrower, at its own expense, shall execute
and deliver to the Administrative Agent in exchange for the Revolving Credit
Note of the transferor Lender a new Revolving Credit Note to the order of such
Purchasing Lender in an amount equal to the Revolving Credit Commitment assumed
by it pursuant to such Assignment and Acceptance and, if the transferor Lender
has retained Revolving Credit Commitments hereunder, a new Revolving Credit Note
to the order of the transferor Lender in an amount equal

                                       75
<PAGE>
to the Revolving Credit Commitment retained by it hereunder. Such new Revolving
Credit Notes shall be dated the Closing Date, and shall otherwise be in the form
of the Revolving Credit Note replaced thereby. The Revolving Credit Notes
surrendered by the transferor Lender shall be returned by the Administrative
Agent to the Borrower marked "cancelled."

                  (d) The Administrative Agent, on behalf of the Borrower, shall
maintain at its address referred to in Section 11.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders and the Revolving Credit
Commitment of, and principal amount of the Revolving Credit Loans owing to, each
Lender from time to time. The entries in the Register shall be conclusive, in
the absence of manifest error, and the Borrower, the Administrative Agent and
the Lenders may treat each Person whose name is recorded in the Register as the
owner of the Revolving Credit Loan recorded therein for all purposes of this
Agreement, notwithstanding any notice to the contrary. Any assignment of any
Revolving Credit Loan or other Obligations hereunder not evidenced by a
Revolving Credit Note shall be effective only upon appropriate entries with
respect thereto being made in the Register. The Register shall be available for
inspection by the Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by a transferor Lender and Purchasing Lender (and, in the case of a Purchasing
Lender that is not then a Lender or an affiliate thereof, by the Borrower and
the Administrative Agent) together with payment to the Administrative Agent of a
registration and processing fee of $4,000, the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the Transfer
Effective Date determined pursuant thereto record the information contained
therein in the Register and give notice of such acceptance and recordation to
the Lenders and the Borrower.

                  (f) The Borrower authorizes each Lender to disclose to any
Participant or Purchasing Lender (each, a "Transferee") and any prospective
Transferee any and all financial information in such Lender's possession
concerning the Borrower and its Affiliates which has been delivered to such
Lender by or on behalf of the Borrower pursuant to this Agreement or which has
been delivered to such Lender by or on behalf of the Borrower in connection with
such Lender's credit evaluation of the Borrower and its Affiliates prior to
becoming a party to this Agreement.

                  (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section concerning assignments of
Revolving Credit Loans and Revolving Credit Notes relate only to absolute
assignments and that such provisions do not prohibit assignments creating
security interests, including, without limitation, any pledge or assignment by a
Lender of any Revolving Credit Loan or Revolving Credit Note to any Federal
Reserve Bank in accordance with applicable law without any notice to or consent
of the Borrower or the Administrative Agent.

         Section 11.7 Adjustments; Set-off.

                  (a) If any Lender (a "benefitted Lender") shall at any time
receive any payment of all or part of its Loans or the Reimbursement Obligations
owing to it, or interest thereon, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-

                                       76
<PAGE>
off, pursuant to events or proceedings of the nature referred to in Article
IX(i), or otherwise), in a greater proportion than any such payment to or
collateral received by any other Lender, if any, in respect of such other
Lender's Loans of the same type or the Reimbursement Obligations owing to it, as
the case may be, or interest thereon, such benefitted Lender shall purchase for
cash from the other Lenders a participating interest in such portion of each
such other Lender's Loan or the Reimbursement Obligations owing to it, or shall
provide such other Lenders with the benefits of any such collateral, or the
proceeds thereof, as shall be necessary to cause such benefitted Lender to share
the excess payment or benefits of such collateral or proceeds ratably with each
of the Lenders; provided, however, that if all or any portion of such excess
payment or benefits is thereafter recovered from such benefitted Lender, such
purchase shall be rescinded, and the purchase price and benefits returned, to
the extent of such recovery, but without interest.

                  (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder or under the Revolving Credit Notes (whether at the stated
maturity, by acceleration or otherwise) to set-off and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Lender or
any branch or agency thereof to or for the credit or the account of the
Borrower. Each Lender agrees promptly to notify the Borrower and the
Administrative Agent after any such set-off and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of
such set-off and application.

         Section 11.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

         Section 11.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         Section 11.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Administrative Agent and the
Lenders with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by the Administrative Agent or any
Lender relative to subject matter hereof not expressly set forth or referred to
herein or in the other Loan Documents.

         Section 11.11 Usury Savings Clause. It is the intention of the parties
hereto to comply with applicable usury laws (now or hereafter enacted);
accordingly, notwithstanding any provision to the contrary in this Agreement,
the Revolving Credit Notes, any of the other Loan Documents or any other
document related hereto, in no event shall this Agreement or any such

                                       77
<PAGE>
other document require the payment or permit the collection of interest in
excess of the maximum amount permitted by such laws. If from any circumstances
whatsoever, fulfillment of any provision of this Agreement or of any other
document pertaining hereto or thereto, shall involve transcending the limit of
validity prescribed by applicable law for the collection or charging of
interest, then, ipso facto, the obligation to be fulfilled shall be reduced to
the limit of such validity, and if from any such circumstances the
Administrative Agent and the Lenders shall ever receive anything of value as
interest or deemed interest by applicable law under this Agreement, the
Revolving Credit Notes, any of the other Loan Documents or any other document
pertaining hereto or otherwise an amount that would exceed the highest lawful
rate, such amount that would be excessive interest shall be applied to the
reduction of the principal amount owing under the Revolving Credit Notes or on
account of any other indebtedness of the Borrower, and not to the payment of
interest, or if such excessive interest exceeds the unpaid balance of principal
of such indebtedness, such excess shall be refunded to the Borrower. In
determining whether or not the interest paid or payable with respect to any
indebtedness of the Borrower to the Administrative Agent and the Lenders, under
any specified contingency, exceeds the Highest Lawful Rate (as hereinafter
defined), the Borrower, the Administrative Agent and the Lenders shall, to the
maximum extent permitted by applicable law, (a) characterize any non-principal
payment as an expense, fee or premium rather than as interest, (b) exclude
voluntary prepayments and the effects thereof, (c) amortize, prorate, allocate
and spread the total amount of interest throughout the full term of such
indebtedness so that interest thereon does not exceed the maximum amount
permitted by applicable law, and/or (d) allocate interest between portions of
such indebtedness, to the end that no such portion shall bear interest at a rate
greater than that permitted by applicable law.

         To the extent that Article 5069-1D.001 et seq., as amended, of the
Texas Revised Civil Statutes is relevant to the Administrative Agent and the
Lenders for the purpose of determining the Highest Lawful Rate, the
Administrative Agent and the Lenders hereby elect to determine the applicable
rate ceiling under such Article by the indicated (weekly) rate ceiling from time
to time in effect. Nothing set forth in this Section 11.11 is intended to or
shall limit the effect or operation of Section 11.12. In no event shall Chapter
346 of the Texas Finance Code (which regulates certain revolving credit loan
accounts) apply to this Agreement or the Revolving Credit Notes.

          For purposes of this Section 11.11, "Highest Lawful Rate" shall mean
the maximum rate of nonusurious interest that may be contracted for, charged,
taken, reserved or received on the Revolving Credit Notes under laws applicable
to the Administrative Agent and the Lenders.

         Section 11.12 GOVERNING LAW. THIS AGREEMENT AND THE REVOLVING CREDIT
NOTES AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE
REVOLVING CREDIT NOTES SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

         Section 11.13 Submission To Jurisdiction; Waivers. The Borrower hereby
irrevocably and unconditionally:

                                       78
<PAGE>

                  (a) submits for itself and its property in any legal action or
proceeding relating to this Agreement and the other Loan Documents to which it
is a party, or for recognition and enforcement of any judgment in respect
thereof, to the non-exclusive general jurisdiction of the Courts of the State of
New York, the courts of the United States of America for the Southern District
of New York, and appellate courts from any thereof;

                  (b) consents that any such action or proceeding may be brought
in such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

                  (c) agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at its address set forth in Section 11.2 or at such other address of
which the Administrative Agent shall have been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction; and

                  (e) waives, to the maximum extent not prohibited by law, any
right it may have to claim or recover in any legal action or proceeding referred
to in this Section any special, exemplary or punitive damages (including,
without limitation, damages arising from the use of electronic,
telecommunications or other information transmissions systems in connection with
the Loan Documents).

         Section 11.14 Acknowledgements. The Borrower hereby acknowledges that:

                  (a) it has been advised by counsel in the negotiation,
execution and delivery of this Agreement and the Revolving Credit Notes and the
other Loan Documents;

                  (b) neither the Administrative Agent nor any Lender has any
fiduciary relationship with or duty to the Borrower or any other Loan Party
arising out of or in connection with this Agreement or any of the other Loan
Documents, and the relationship between Administrative Agent and Lenders, on one
hand, and the Borrower and the other Loan Parties, on the other hand, in
connection herewith or therewith is solely that of debtor and creditor; and

                  (c) no joint venture exists among the Lenders or among the
Borrower and the other Loan Parties and the Lenders.

         Section 11.15 Confidentiality. Each of the Administrative Agent and
each Lender agrees that it will hold in confidence, any information provided to
such Person pursuant to this Agreement; provided, that nothing in this Section
11.15 shall be deemed to prevent the disclosure by the Administrative Agent or
any Lender of any such information (a) to any employee, officer, director,
accountant, attorney or consultant of such Person, or any examiner or other
Governmental Authority, (b) that has been or is made public by EPEPC, the
Borrower or any of its Subsidiaries or Affiliates or by any third party without
breach of this Agreement or that otherwise becomes generally available to the
public other than as a result of a disclosure in violation of this Section
11.15, (c) that is or becomes available to any such Person from a third

                                       79

Requirement of Law, including to any bank examiners or regulatory authorities,

         Section 11.16 WAIVERS OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE
AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY

         Section 11.17 ACKNOWLEDGEMENT OF NO CLAIMS, OFFSETS OR DEFENSES;
RELEASE BY THE LOAN PARTIES. BORROWER, ON BEHALF OF ITSELF AND EACH OF THE OTHER
LOAN PARTIES, ACKNOWLEDGES THAT NO LOAN PARTY NOR ANY OF THEIR RESPECTIVE

         Section 11.18 Releases.

                  (a) At such time as the Revolving Credit Loans, the
Reimbursement Obligations and any other obligations under this Agreement shall
have been paid in full, the Revolving Credit Commitments have been terminated
and no Letters of Credit shall be outstanding, the Collateral shall be released
from the Liens created by the Loan Documents, and

                                       80
<PAGE>
all obligations (other than those expressly stated to survive such termination)
of the Administrative Agent and each Loan Party thereunder and under the other
Loan Documents shall terminate, all without delivery of any instrument or
performance of any act by any party, and all rights to the Collateral shall
revert to the respective Loan Parties. At the request and expense of any Loan
Party following any such termination, the Administrative Agent shall deliver to
such Loan Party any Collateral held by the Administrative Agent under the
Security Documents, and execute and deliver to such Loan Party such documents as
such Loan Party shall reasonably request to evidence such termination.

                  (b) If any of the Collateral shall be sold, transferred or
otherwise disposed of by any Loan Party in a transaction permitted by this
Agreement or such Loan Party is designated as an Unrestricted Subsidiary in
accordance with the terms of this Agreement, then the Lenders authorize the
Administrative Agent, at the request and expense of such Loan Party, to execute
and deliver to such Loan Party all releases or other documents reasonably
necessary or desirable for the release of the Liens created by the applicable
Security Documents on such Collateral. At the request and sole expense of the
Borrower, the Lenders authorize the Administrative Agent to release a Loan Party
from its obligations under the applicable Security Document in the event that
all the Capital Stock of such Loan Party shall be sold, transferred or otherwise
disposed of in a transaction permitted by this Agreement or such Loan Party is
designated as an Unrestricted Subsidiary in accordance with the terms of this
Agreement, provided that the Borrower shall have delivered to the Administrative
Agent, at least five Business Days prior to the date of the proposed release, a
written request for release identifying the relevant Loan Party and the terms of
the sale or other disposition in reasonable detail, including the price thereof
and any expenses in connection therewith, together with a certification by the
Borrower stating that such transaction is in compliance with this Agreement and
the other Loan Documents.

         Section 11.19 Co-Borrower's Obligations. The Co-Borrower is a party
hereto for purposes of providing co-extensive obligors for the Obligations (on a
joint and several basis), although the parties acknowledge that the Co-Borrower
shall not have any substantial assets or other property. All references in this
Agreement and the other Loan Documents to the "Borrower" shall be deemed to
include a reference to the Co-Borrower, mutatis mutandis, whether or not actual
reference is made thereto; provided, that, without limiting the generality of
the foregoing, any obligations by any of the parties hereto to the Borrower
shall be deemed fulfilled with respect to the Co-Borrower when fulfilled with
respect to the Borrower.

         Section 11.20 Intercreditor Agreement. Each Lender (including each
Purchasing Lender which becomes a Lender) consents and agrees to the provisions
of the Intercreditor Agreement, including the indemnity provisions set forth in
Section 5 thereof.

                           Restricted Subsidiary or (B) such asset is acquired
                           by the Borrower or any Restricted Subsidiary, as the
                           case may be, and the proceeds thereof."

                            EL PASO ENERGY PARTNERS'
                   FIFTH AMENDED AND RESTATED CREDIT AGREEMENT

                             THE CHACO TRANSACTIONS

I.       THE CHACO PLANT

         The Chaco Plant, the third largest natural gas processing plant in the
United States measured by liquids produced, is located in the San Juan Basin in
New Mexico. It is capable of processing up to 600 Mmcf/d of natural gas and
handling up to 50,000 bbls/d of NGLs. The Chaco Plant is a state of the art
cryogenic plant that uses high pressures and extremely low temperatures to
remove water, impurities and excess hydrocarbon liquids from the raw natural gas
stream and recover ethane as well as propane and the heavier hydrocarbons. The
Chaco Plant receives and processes natural gas from the San Juan Gathering
System (the "Gathering System"), an over 5,500 mile natural gas gathering system
in New Mexico owned and operated by an affiliate of El Paso Field Services
("Field Services"). Field Services, directly or through subsidiaries, owns
(beneficially) and operates the Chaco Plant, subject to a sale-leaseback
financing agreement.

II.      TRANSACTION OVERVIEW

         In a series of related transactions, the Partnership (through a
Restricted Subsidiary under the Credit Agreement) will pay approximately $198.5
million to acquire title to and other interests in the Chaco Plant and certain
related rights and interests for the next 20 years; including the dedication of
all uncommitted processing rights that Field Services has with respect to
natural gas gathered by the Gathering System. In addition, Field Services has
agreed to continue to acquire processing rights and dedicate the underlying
natural gas to the Chaco Plant. Natural gas delivered by Field Services will
have first priority on plant capacity. Field Services will pay the Partnership
13.44cents for each Mcf of natural gas processed at the plant by Field Services.
The Partnership will bear all costs of ownership and operations of the Chaco
Plant. Field Services personnel will continue to operate the plant for the
Partnership.

III.     CURRENT STATUS OF CHACO PLANT

         Field Services, through a subsidiary, constructed the Chaco Plant in
1995. Field Services financed a portion of the Chaco Plant construction through
a sale-leaseback transaction in which Field Services sold the Chaco Plant to a
Massachusetts business trust (the "Trust") created by the lenders and leased the
Chaco Plant back from the Trust through October 2002. The transaction
effectively was structured as follows:

         (1)  The lenders capitalized the Trust through a loan and a small
              equity contribution, and were issued notes to evidence the loan
              and certificates to evidence the equity from the Trust;

                                      A-1

         (2)  The Trust purchased the Chaco Plant using the lenders' investment
              and loaned funds, and granted liens covering the Chaco Plant in
              favor of the lenders;

         (3)  The Trust leased the Chaco Plant back to Field Services;

         (4)  Field Services has the obligation to operate the Chaco Plant;

         (5)  Field Services has the right to repurchase the plant in October
              2002 for approximately $72 million; and

         (6)  If Field Services does not exercise its repurchase right, it has
              to pay a substantial forfeiture payment to the Trust.

State Street Bank and Trust Company is currently the trustee of the Trust.

IV.      THE CURRENTLY CONTEMPLATED CHACO TRANSACTIONS

         In order for the Partnership's Restricted Subsidiary to acquire its
interests in the Chaco Plant, the following transactions will occur:

         (1)  The Partnership will acquire title to the Plant, subject to the
              Chaco lease documents, by becoming the beneficiary of the Trust
              through the purchase of the notes and certificates issued by the
              Trust to the sale-leaseback lenders;

         (2)  The Restricted Subsidiary will become agent for the Trust;

         (3)  Another Restricted Subsidiary will become trustee of the Trust;

         (4)  The Trust will become a Restricted Subsidiary and, accordingly,
              will guarantee the indebtedness outstanding under the Credit
              Agreement and pledge its assets as collateral for the Credit
              Agreement;

         (5)  The Restricted Subsidiary and Field Services will enter into a
              Tolling Agreement under which (a) Field Services will dedicate all
              of the natural gas received into the Gathering System to the Chaco
              Plant for processing (except for certain amounts of natural gas
              that have previously been dedicated to the nearby Conoco/Blanco
              Plant, and certain other amounts of natural gas that will be used
              for fuel use, farm taps and lift gas, or temporarily offloaded due
              to capacity constraints on the Gathering System pursuant to terms
              of existing gathering agreements), (b) Field Services will be
              obligated to attempt to acquire additional processing rights for
              gas gathered by the Gathering System, (c) gas delivered to the
              Chaco Plant by Field Services will have a processing priority over
              other gas; and

         (6)  Field Services personnel will continue to operate and provide
              other services related to the Chaco Plant.
