                  THREE-YEAR REVOLVING CREDIT AGREEMENT (the "Agreement"), dated
                  as of May 1, 2002, among TXU Corp., a Texas corporation (the
                  "Borrower"); the lenders listed in Schedule 2.01 (together
                  with their successors and assigns, the "Lenders"); and
                  Citibank, N.A. ("Citibank"), as administrative agent for the
                  Lenders (in such capacity, the "Agent").

         The Borrower has requested the Lenders to provide the credit facility
hereinafter described in the amounts and on the terms and conditions set forth
herein, the Lenders have so agreed on the terms and conditions set forth herein
and the Agent has agreed to act as agent for the Lenders, on such terms and
conditions;

         Accordingly, the parties hereto agree as follows:

                                    ARTICLE I
                            DEFINITIONS; CONSTRUCTION

         SECTION 1.01. Defined Terms.

         As used in this Agreement, the following terms shall have the meanings
         specified below:

                  "ABR Borrowing" shall mean a Borrowing comprised of ABR Loans.

                  "ABR Loan" shall mean any Loan bearing interest at a rate
         determined by reference to the Alternate Base Rate in accordance with
         the provisions of Article II or any Eurodollar Loan converted (pursuant
         to Section 2.08 or 2.12(a)(ii)) to a loan bearing interest at a rate
         determined by reference to the Alternate Base Rate.

                  "Acquisition Date" shall mean the date as of which a person or
         group of related persons first acquires more than 30% of the
         outstanding Voting Shares of the Borrower (within the meaning of
         Section 13(d) or 14(d) of the Exchange Act and the applicable rules and
         regulations thereunder).

                  "Administrative Fees" shall have the meaning assigned to such
         term in Section 2.04(b).

                  "Affiliate" shall mean, when used with respect to a specified
         person, another person that directly or indirectly controls or is
         controlled by or is under common control with the person specified.

                  "Agent" shall have the meaning given such term in the preamble
         hereto.

                  "Agreement" shall have the meaning given such term in the
         preamble hereto.

                  "Alternate Base Rate" shall mean, for any day, a rate per
         annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to
         the greater of (i) the Federal Funds Effective Rate in effect on such
         day plus 1/2 of 1% and (ii) the Prime Rate in effect on such day. For
         purposes hereof, "Prime Rate" shall mean the rate of interest per annum

<PAGE>

                                                                               2

         publicly announced from time to time by the Agent as its "base" rate in
         effect at its principal office in New York City; each change in the
         Prime Rate shall be effective on the date such change is publicly
         announced as effective; and "Federal Funds Effective Rate" shall mean,
         for any day, the weighted average of the rates on overnight Federal
         funds transactions with members of the Federal Reserve System arranged
         by Federal funds brokers, as released on the next succeeding Business
         Day by the Federal Reserve Bank of New York, or, if such rate is not so
         released for any day which is a Business Day, the arithmetic average
         (rounded upwards to the next 1/100th of 1%), as determined by the
         Agent, of the quotations for the day of such transactions received by
         the Agent from three Federal funds brokers of recognized standing
         selected by it. If for any reason the Agent shall have determined
         (which determination shall be conclusive absent manifest error;
         provided that the Agent shall, upon request, provide to the Borrower a
         certificate setting forth in reasonable detail the basis for such
         determination) that it is unable to ascertain the Federal Funds
         Effective Rate for any reason, including the inability of the Agent to
         obtain sufficient quotations in accordance with the terms thereof, the
         Alternate Base Rate shall be determined without regard to clause (i) of
         the first sentence of this definition until the circumstances giving
         rise to such inability no longer exist. Any change in the Alternate
         Base Rate due to a change in the Prime Rate or the Federal Funds
         Effective Rate shall be effective on the effective date of such change
         in the Prime Rate or the Federal Funds Effective Rate, respectively.

                  "Applicable Margin" shall mean, for any Type of Loan at any
         time, the percentage per annum set forth below corresponding to such
         Type of Loan in the column under the Applicable Rating Level at the
         time of determination.

                  "Applicable Rating Level" shall mean, at any time, the level
         set forth below in the row next to the then applicable Debt Rating. If
         there is a difference of one level in the Debt Ratings assigned by S&P
         and Moody's, then the higher Debt Rating shall be used for purposes of
         determining the Applicable Rating Level and if there is a difference of
         more than one level in the Debt Ratings assigned by S&P and Moody's,
         then the Debt Rating one level higher than the lower Debt Rating will
         be used for purposes of determining the Applicable Rating Level. Any
         change in the Applicable Rating Level shall be effective on the date on
         which the applicable rating agency announces any change in the
         applicable Debt Rating.

                                   THE CREDITS

         SECTION 2.01.  Commitments.

         Subject to the terms and conditions and relying upon the
representations and warranties herein set forth, each Lender agrees, severally
and not jointly, to make Loans, at any time and from time to time until the
earlier of the Maturity Date and the termination of the Commitment of such
Lender, to the Borrower in an aggregate principal amount at any time outstanding
not to exceed such Lender's Commitment, subject, however, to the conditions that
(i) at no time shall the outstanding aggregate principal amount of all Loans
exceed the Total Commitment, (ii) at no time shall the outstanding aggregate
principal amount of all Loans made by any Lender exceed the amount of such
Lender's Commitment and (iii) at all times, the outstanding aggregate principal
amount of all Loans made by each Lender to the Borrower shall equal the product
of (A) the percentage which such Lender's Commitment represents of the Total
Commitment times (B) the outstanding aggregate principal amount of all Loans
made to the Borrower.

         Within the foregoing limits, the Borrower may borrow, pay or prepay and
reborrow Loans hereunder, on and after the date of this Agreement and prior to
the Maturity Date, subject to the terms, conditions and limitations set forth
herein.

         SECTION 2.02.  Loans.

         (a)   Each Loan shall be made as part of a Borrowing consisting of
Loans made by the Lenders ratably in accordance with their respective
Commitments; provided, however, that the failure of any Lender to make any Loan
shall not in itself relieve any other Lender of its obligation to lend hereunder
(it being understood, however, that no Lender shall be responsible for the
failure of any other Lender to make any Loan required to be made by such other
Lender). The Loans comprising any Borrowing shall be in an aggregate principal
amount that is an integral multiple of $5,000,000 and not less than $10,000,000
(or an aggregate principal amount equal to the remaining balance of the
available Commitments).

         (b)   Each Borrowing shall be comprised entirely of Eurodollar Loans or
ABR Loans, as the Borrower may request pursuant to Section 2.03. Each Lender may
at its option make any Eurodollar Loan by causing any domestic or foreign branch
or Affiliate of such Lender to make such Loan; provided that any exercise of
such option shall not affect the obligation of the Borrower to repay such Loan
in accordance with the terms of this Agreement. Borrowings of more than one Type
may be outstanding at the same time.

         (c)   Subject to paragraph (d) below, each Lender shall make each Loan
to be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Agent in New York, New York, not later than
noon, New York City time, and the Agent shall by 2:00 p.m., New York City time,
credit the amounts so received to the account or accounts specified from time to
time in one or more notices delivered by the Borrower to the Agent or, if a
Borrowing shall not occur on such date because any condition precedent herein
specified shall not have been met, return the amounts so received to the
respective Lenders. Loans shall be made by the Lenders pro rata in accordance
with Section 2.13. Unless the Agent shall have

                                                                              16

received notice from a Lender prior to the date of any Borrowing that such
Lender will not make available to the Agent such Lender's portion of such
Borrowing, the Agent may assume that such Lender has made such portion available
to the Agent on the date of such Borrowing in accordance with this paragraph (c)
and the Agent may, in reliance upon such assumption, make available to the
Borrower on such date a corresponding amount.  If and to the extent that such
Lender shall not have made such portion available to the Agent, such Lender and
the Borrower (without waiving any claim against such Lender for such Lender's
failure to make such portion available) severally agree to repay to the Agent
forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower until
the date such amount is repaid to the Agent, at (i) in the case of the Borrower,
the interest rate applicable at the time to the Loans comprising such Borrowing
and (ii) in the case of such Lender, the Federal Funds Effective Rate. If such
Lender shall repay to the Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement.

         (d)   The Borrower may refinance all or any part of any Borrowing with
a Borrowing of the same or a different Type, subject to the conditions and
limitations set forth in this Agreement. Any Borrowing or part thereof so
refinanced shall be deemed to be repaid or prepaid in accordance with Section
2.05 or 2.10, as applicable, with the proceeds of a new Borrowing, and the
proceeds of the new Borrowing, to the extent they do not exceed the principal
amount of the Borrowing being refinanced, shall not be paid by the Lenders to
the Agent or by the Agent to the Borrower pursuant to paragraph (c) above.

         SECTION 2.03.  Borrowing Procedure.

         In order to request a Borrowing, the Borrower shall hand deliver or
telecopy to the Agent a duly completed Borrowing Request in the form of Exhibit
A (i) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York
City time, three Business Days before such Borrowing, and (ii) in the case of an
ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day
before such Borrowing. Such notice shall be irrevocable and shall in each case
specify (A) whether the Borrowing then being requested is to be a Eurodollar
Borrowing or an ABR Borrowing; (B) the date of such Borrowing (which shall be a
Business Day) and the amount thereof; and (C) if such Borrowing is to be a
Eurodollar Borrowing, the Interest Period with respect thereto, which shall not
end after the Maturity Date. If no election as to the Type of Borrowing is
specified in any such notice, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is
specified in any such notice, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration (subject to the limitations set forth
in the definition of "Interest Period"). If the Borrower shall not have given
notice in accordance with this Section 2.03 of its election to refinance a
Borrowing prior to the end of the Interest Period in effect for such Borrowing,
then the Borrower shall (unless such Borrowing is repaid at the end of such
Interest Period) be deemed to have given notice of an election to refinance such
Borrowing with an ABR Borrowing. Notwithstanding any other provision of this
Agreement to the contrary, no Borrowing shall be requested if the Interest
Period with respect thereto would end after the scheduled Maturity Date. The
Agent shall promptly advise the Lenders of any notice given pursuant to this
Section 2.03 and of each Lender's portion of the requested Borrowing.

                                                                              17

         SECTION 2.04.  Fees.

         (a)   The Borrower agrees to pay to each Lender, through the Agent, on
each March 31, June 30, September 30 and December 31 (with the first payment
being due on June 30, 2002) and on each date on which the Commitment of such
Lender shall be terminated or reduced as provided herein, a commitment fee (a
"Commitment Fee"), at a rate per annum equal to the applicable Commitment Fee
Percentage from time to time in effect on the amount of the sum of the unused
Commitment of such Lender, during the preceding quarter (or other period
commencing on the date of this Agreement or ending on the Maturity Date or any
date on which the Commitment of such Lender shall be terminated). All Commitment
Fees shall be computed on the basis of the actual number of days elapsed in a
year of 360 days. The Commitment Fee due to each Lender shall commence to accrue
on the date of this Agreement, and shall cease to accrue on the date of
termination of the Commitment of such Lender as provided herein.

         (b)   The Borrower agrees to pay the Agent, for its own account, the
administrative fees in the amounts and at the times provided for in the Letter
Agreement (the "Administrative Fees").

         (c)   All Fees shall be paid on the dates due, in immediately available
funds, to the Agent for distribution, if and as appropriate, among the Lenders.
Once paid, none of the Fees shall be refundable under any circumstances.

         SECTION 2.05. Repayment of Loans; Evidence of Indebtedness.

         (a)   The outstanding principal balance of each Loan shall be due and
payable on the last day of the Interest Period applicable thereto and on the
Maturity Date.

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

         (c)   The Agent shall maintain accounts in which it will record (i) the
amount of each Loan made hereunder, the Type of each Loan made and the Interest
Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder
and (iii) the amount of any sum received by the Agent hereunder from the
Borrower and each Lender's share thereof.

         (d)   The entries made in the accounts maintained pursuant to
paragraphs (b) and (c) of this Section 2.05 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations therein recorded; provided, however, that the failure of any Lender
or the Agent to maintain such accounts or any error therein shall not in any
manner affect the obligations of the Borrower to repay the Loans in accordance
with their terms.

         SECTION 2.06.  Interest on Loans.

         (a)   Subject to the provisions of Section 2.07, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a

<PAGE>

                                                                              18

year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin from time to time
in effect.

         (b)   Subject to the provisions of Section 2.07, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of (i) 365 or 366 days, as the case may be,
for periods during which the Alternate Base Rate is determined by reference to
the Prime Rate and (ii) 360 days for other periods) at a rate per annum equal to
the Alternate Base Rate plus the Applicable Margin from time to time in effect.

         (c)   Interest on each Loan shall be payable on each Interest Payment
Date applicable to such Loan except as otherwise provided in this Agreement. The
applicable LIBO Rate or Alternate Base Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the Agent,
and such determination shall be conclusive absent manifest error; provided that
the Agent shall, upon request, provide to the Borrower a certificate setting
forth in reasonable detail the basis for such determination.

         SECTION 2.07.  Default Interest.

         If the Borrower shall default in the payment of the principal of or
interest on any Loan or any other amount becoming due hereunder, whether by
scheduled maturity, notice of prepayment, acceleration or otherwise, the
Borrower shall on demand from time to time from the Agent pay interest, to the
extent permitted by law, on such defaulted amount up to (but not including) the
date of actual payment (after as well as before judgment) at a rate per annum
(computed as provided in Section 2.06(b)) equal to the Alternate Base Rate plus
the Applicable Margin for ABR Loans plus 2%.

         SECTION 2.08. Alternate Rate of Interest.

         In the event, and on each occasion, that on the day two Business Days
prior to the commencement of any Interest Period for a Eurodollar Borrowing the
Agent shall have determined (i) that dollar deposits in the principal amounts of
the Eurodollar Loans comprising such Borrowing are not generally available in
the London interbank market or (ii) that reasonable means do not exist for
ascertaining the LIBO Rate, the Agent shall, as soon as practicable thereafter,
give telecopy notice of such determination to the Borrower and the Lenders. In
the event of any such determination under clause (i) or (ii) above, until the
Agent shall have advised the Borrower and the Lenders that the circumstances
giving rise to such notice no longer exist any request by the Borrower for a
Eurodollar Borrowing pursuant to Section 2.03 shall be deemed to be a request
for an ABR Borrowing. In the event the Required Lenders notify the Agent that
the rates at which dollar deposits are being offered will not adequately and
fairly reflect the cost to such Lenders of making or maintaining Eurodollar
Loans during such Interest Period, the Agent shall notify the Borrower of such
notice and until the Required Lenders shall have advised the Agent that the
circumstances giving rise to such notice no longer exist, any request by the
Borrower for a Eurodollar Borrowing shall be deemed a request for an ABR
Borrowing. Each determination by the Agent hereunder shall be made in good faith
and shall be conclusive absent manifest error; provided that the Agent, shall,
upon request, provide to the Borrower a certificate setting forth in reasonable
detail the basis for such determination.

         SECTION 2.09. Termination and Reduction of Commitments.

         (a)   The Commitments shall be automatically terminated on the Maturity
Date.

         (b)   Upon at least two Business Days' prior irrevocable written notice
to the Agent, the Borrower may at any time in whole permanently terminate, or
from time to time in part permanently reduce, the Total Commitment; provided,
however, that (i) each partial reduction of the Total Commitment shall be in an
integral multiple of $10,000,000 and (ii) no such termination or reduction shall
be made that would reduce the Total Commitment to an amount less than (1) the
aggregate principal amount of outstanding Loans on the date of such termination
or reduction (after giving effect to any prepayment made pursuant to Section
2.10) or (2) $50,000,000, unless the result of such termination or reduction
referred to in this clause (2) is to reduce the Total Commitment to $0. The
Agent shall advise the Lenders of any notice given pursuant to this Section
2.09(b) and of each Lender's portion of any such termination or reduction of the
Total Commitment.

         (c)   Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments. The
Borrower shall pay to the Agent for the account of the Lenders, on the date of
each termination or reduction of the Total Commitment, the Commitment Fees on
the amount of the Commitments so terminated or reduced accrued through the date
of such termination or reduction.

         SECTION 2.10.  Prepayment.

         (a)   The Borrower shall have the right at any time and from time to
time to prepay any Borrowing, in whole or in part, upon giving telecopy notice
(or telephone notice promptly confirmed by telecopy) to the Agent: (i) before
11:00 a.m., New York City time, three Business Days prior to prepayment, in the
case of Eurodollar Loans, and (ii) before 11:00 a.m., New York City time, one
Business Day prior to prepayment, in the case of ABR Loans; provided, however,
that each partial prepayment shall be in an amount which is an integral multiple
of $5,000,000 and not less than $10,000,000.

         (b)   Each notice of prepayment shall specify the prepayment date and
the principal amount of each Borrowing (or portion thereof) to be prepaid, shall
be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein. All
prepayments under this Section 2.10 shall be subject to Section 8.05 but
otherwise without premium or penalty. All prepayments under this Section 2.10
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

         SECTION 2.11. Reserve Requirements; Change in Circumstances.

         (a)   Notwithstanding any other provision herein, if after the date of
this Agreement any change in applicable law or regulation or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof (whether or not having the
force of law) shall change the basis of taxation of payments to any Lender
hereunder (except for changes in respect of taxes on the overall net income of
such Lender or its lending office imposed by the jurisdiction in which such
Lender's principal executive office or

<PAGE>

                                                                              20

lending office is located), or shall result in the imposition, modification or
applicability of any reserve, special deposit or similar requirement against
assets of, deposits with or for the account of or credit extended by any Lender,
or shall result in the imposition on any Lender or the London interbank market
of any other condition affecting this Agreement, such Lender's Commitment or any
Eurodollar Loan made by such Lender, and the result of any of the foregoing
shall be to increase the cost to such Lender of making or maintaining any
Eurodollar Loan or to reduce the amount of any sum received or receivable by
such Lender hereunder (whether of principal, interest or otherwise) by an amount
deemed by such Lender to be material, then the Borrower shall, upon receipt of
the notice and certificate provided for in Section 2.11(c), promptly pay to such
Lender such additional amount or amounts as will compensate such Lender for such
additional costs incurred or reduction suffered.

         (b)   If any Lender shall have determined that the adoption of any law,
rule, regulation or guideline arising out of the July 1988 report of the Basle
Committee on Banking Regulations and Supervisory Practices entitled
"International Convergence of Capital Measurement and Capital Standards," or the
adoption after the date hereof of any other law, rule, regulation or guideline
regarding capital adequacy, or any change in any of the foregoing or in the
interpretation or administration of any of the foregoing by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any lending office of
such Lender) or any Lender's holding company with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on such Lender's capital or on the capital of such
Lender's holding company, if any, as a consequence of this Agreement, such
Lender's Commitment or the Loans made by such Lender pursuant hereto to a level
below that which such Lender or such Lender's holding company could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's policies and the policies of such Lender's holding company with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time such additional amount or amounts as will compensate such
Lender for any such reduction suffered will be paid by the Borrower to such
Lender.

         (c)   A certificate of each Lender setting forth such amount or amounts
as shall be necessary to compensate such Lender or its holding company as
specified in paragraph (a) or (b) above, and containing an explanation, in
reasonable detail, of the manner in which such amount or amounts shall have been
determined, shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay each Lender the amount shown as due on
any such certificate delivered by it within 10 days after its receipt of the
same. Each Lender shall give prompt notice to the Borrower of any event of which
it has knowledge, occurring after the date hereof, that it has determined will
require compensation by the Borrower pursuant to this Section; provided,
however, that failure by such Lender to give such notice shall not constitute a
waiver of such Lender's right to demand compensation hereunder.

         (d)   Failure on the part of any Lender to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Lender's right to demand compensation with respect to such period or any
other period; provided, however, that no Lender shall be entitled to
compensation under this Section 2.11 for any costs incurred or reductions
suffered with respect

<PAGE>

                                                                              21

to any date unless it shall have notified the Borrower that it will demand
compensation for such costs or reductions under paragraph (c) above not more
than 90 days after the later of (i) such date and (ii) the date on which it
shall have become aware of such costs or reductions. The protection of this
Section shall be available to each Lender regardless of any possible contention
of the invalidity or inapplicability of the law, rule, regulation, guideline or
other change or condition which shall have occurred or been imposed.

         (e)   Each Lender agrees that it will designate a different lending
office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the reasonable judgment of such Lender, be
disadvantageous to such Lender.

         SECTION 2.12.  Change in Legality.

         (a)   Notwithstanding any other provision herein, if any change in any
law or regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written notice to the Borrower and to the Agent, such Lender may:

               (i)      declare that Eurodollar Loans will not thereafter be
         made by such Lender hereunder, whereupon any request for a Eurodollar
         Borrowing shall, as to such Lender only, be deemed a request for an
         ABR Loan unless such declaration shall be subsequently withdrawn (any
         Lender delivering such a declaration hereby agreeing to withdraw such
         declaration promptly upon determining that such event of illegality no
         longer exists); and

               (ii)     require that all outstanding Eurodollar Loans made by it
         be converted to ABR Loans, in which event all such Eurodollar Loans
         shall be automatically converted to ABR Loans as of the effective date
         of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the Eurodollar Loans which would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

         (b)   For purposes of this Section 2.12, a notice by any Lender shall
be effective as to each Eurodollar Loan, if lawful, on the last day of the
Interest Period currently applicable to such Eurodollar Loan; in all other cases
such notice shall be effective on the date of receipt.

         SECTION 2.13.  Pro Rata Treatment.

         Except as required under Sections 2.12 and 2.17, each Borrowing, each
payment or prepayment of principal of any Borrowing, each payment of interest on
the Loans, each payment of the Commitment Fees, each reduction of the
Commitments and each refinancing or conversion of any Borrowing with a Borrowing
of any Type, shall be allocated pro rata among the Lenders in accordance with
their respective Commitments (or, if such Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of their

<PAGE>

                                                                              22

outstanding Loans). Each Lender agrees that in computing such Lender's portion
of any Borrowing to be made hereunder, the Agent may, in its discretion, round
each Lender's percentage of such Borrowing to the next higher or lower whole
dollar amount.

         SECTION 2.14.  Sharing of Setoffs.

         Each Lender agrees that if it shall, through the exercise of a right of
banker's lien, setoff or counterclaim, or pursuant to a secured claim under
Section 506 of Title 11 of the United States Bankruptcy Code or other security
or interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, obtain payment (voluntary or involuntary) in
respect of any Loan or Loans as a result of which the unpaid principal portion
of its Loans shall be proportionately less than the unpaid principal portion of
the Loans of any other Lender, it shall be deemed simultaneously to have
purchased from such other Lender at face value, and shall promptly pay to such
other Lender the purchase price for, a participation in the Loans of such other
Lender, so that the aggregate unpaid principal amount of the Loans and
participations in the Loans held by each Lender shall be in the same proportion
to the aggregate unpaid principal amount of all Loans then outstanding as the
principal amount of its Loans prior to such exercise of banker's lien, setoff or
counterclaim or other event was to the principal amount of all Loans outstanding
prior to such exercise of banker's lien, setoff or counterclaim or other event;
provided, however, that, if any such purchase or purchases or adjustments shall
be made pursuant to this Section 2.14 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Loan deemed to have been so purchased may exercise any and all rights of
banker's lien, setoff or counterclaim with respect to any and all moneys owing
by the Borrower to such Lender by reason thereof as fully as if such Lender had
made a Loan in the amount of such participation.

         SECTION 2.15.  Payments.

         (a)   The Borrower shall make each payment (including principal of or
interest on any Borrowing or any Fees or other amounts) hereunder from an
account in the United States not later than 12:00 noon, New York City time, on
the date when due in dollars to the Agent at its offices at Two Penns Way, Suite
200, New Castle, Delaware 19720, Attention: Medium Term Finance, Account:
3685-2248, in immediately available funds. Each such payment shall be made
without off-set, deduction or counterclaim, provided, that the foregoing shall
not constitute a relinquishment or waiver of the Borrower's rights to any
independent claim that the Borrower may have against the Agent or any Lender.

         (b)   Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day, and such extension of time shall in such case
be included in the computation of interest or Fees, if applicable.

                                                                              23

         SECTION 2.16.  Taxes.

         (a)   Any and all payments of principal and interest on any Borrowings,
or of any Fees or indemnity or expense reimbursements by the Borrower hereunder
("Borrower Payments") shall be made, in accordance with Section 2.15, free and
clear of and without deduction for any and all current or future United States
Federal, state and local taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect to such Borrower Payments, but
only to the extent reasonably attributable to such Borrower Payments, excluding
(i) income taxes imposed on the net income of the Agent or any Lender (or any
transferee or assignee thereof, including a participation holder (any such
entity a "Transferee")) and (ii) franchise taxes imposed on the net income of
the Agent or any Lender (or Transferee), in each case by the jurisdiction under
the laws of which the Agent or such Lender (or Transferee) is organized or doing
business through offices or branches located therein, or any political
subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities, collectively or individually, "Taxes").
If the Borrower shall be required to deduct any Taxes from or in respect of any
sum payable hereunder to any Lender (or any Transferee) or the Agent, (i) the
sum payable shall be increased by the amount (an "additional amount") necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.16) such Lender (or Transferee) or
the Agent (as the case may be) shall receive an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

         (b)   In addition, the Borrower shall pay to the relevant United States
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or the
Letter Agreement ("Other Taxes").

         (c)   The Borrower shall indemnify each Lender (or Transferee thereof)
and the Agent for the full amount of Taxes and Other Taxes with respect to
Borrower Payments paid by such Lender (or Transferee) or the Agent, as the case
may be, and any liability (including penalties, interest and expenses (including
reasonable attorney's fees and expenses)) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted by the relevant United States Governmental Authority. A certificate
setting forth and containing an explanation in reasonable detail of the manner
in which such amount shall have been determined and the amount of such payment
or liability prepared by a Lender, or the Agent on behalf of a Lender, absent
manifest error, shall be final, conclusive and binding for all purposes. Such
indemnification shall be made within 30 days after the date the Lender (or
Transferee) or the Agent, as the case may be, makes written demand therefor.

         (d)   If a Lender (or Transferee) or the Agent shall become aware that
it is entitled to claim a refund from a United States Governmental Authority in
respect of Taxes or Other Taxes as to which it has been indemnified by the
Borrower, or with respect to which the Borrower has paid additional amounts,
pursuant to this Section 2.16, it shall promptly notify the Borrower of the
availability of such refund claim and shall, within 30 days after receipt of a
request by the Borrower, make a claim to such United States Governmental
Authority for such refund at the

<PAGE>

                                                                              24
Borrower's expense. If a Lender (or Transferee) or the Agent receives a refund
(including pursuant to a claim for refund made pursuant to the preceding
sentence) in respect of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower had paid
additional amounts pursuant to this Section 2.16, it shall within 30 days from
the date of such receipt pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower
under this Section 2.16 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of such Lender (or Transferee)
or the Agent and without interest (other than interest paid by the relevant
United States Governmental Authority with respect to such refund); provided,
however, that the Borrower, upon the request of such Lender (or Transferee) or
the Agent, agrees to repay the amount paid over to the Borrower (plus penalties,
interest or other charges) to such Lender (or Transferee) or the Agent in the
event such Lender (or Transferee) or the Agent is required to repay such refund
to such United States Governmental Authority.

         (e)   As soon as practicable, but in any event within 30 days, after
the date of any payment of Taxes or Other Taxes by the Borrower to the relevant
United States Governmental Authority, the Borrower will deliver to the Agent, at
its address referred to in Section 8.01, the original or a certified copy of a
receipt issued by such United States Governmental Authority evidencing payment
thereof.

         (f)   Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.16
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

         (g)   Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to the Borrower and the Agent two
copies of either United States Internal Revenue Service Form W-8BEN or Form
W-8ECI, properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or reduced rate of, United States Federal withholding
tax on payments by the Borrower under this Agreement. Such forms shall be
delivered by each Non-U.S. Lender on or before the date it becomes a party to
this Agreement (or, in the case of a Transferee that is a participation holder,
on or before the date such participation holder becomes a Transferee hereunder)
and on or before the date, if any, such Non-U.S. Lender changes its applicable
lending office by designating a different lending office (a "New Lending
Office"). In addition, each Non-U.S. Lender shall deliver such forms promptly
upon the obsolescence or invalidity of any form previously delivered by such
Non-U.S. Lender. Notwithstanding any other provision of this Section 2.16(g), a
Non-U.S. Lender shall not be required to deliver any form pursuant to this
Section 2.16(g) that such Non-U.S. Lender is not legally able to deliver.

         (h)   The Borrower shall not be required to indemnify any Non-U.S.
Lender (including any Transferee), or to pay any additional amounts to any
Non-U.S.  Lender (including any Transferee), in respect of United States
Federal, state or local withholding tax pursuant to paragraph (a) or (c) above
to the extent that (i) the obligation to withhold amounts with respect to United
States Federal, state or local withholding tax existed on the date such Non-U.S.
Lender became a party to this Agreement (or, in the case of a Transferee that is
a participation holder, on the date such participation holder became a
Transferee hereunder) or, with respect to payments to

<PAGE>

                                                                              25

a New Lending Office, the date such Non-U.S. Lender designated such New Lending
Office with respect to a Loan; provided, however, that this clause (i) shall not
apply to any Transferee or New Lending Office that becomes a Transferee or New
Lending Office as a result of an assignment, participation, transfer or
designation made at the request of the Borrower; and provided further, however,
that this clause (i) shall not apply to the extent the indemnity payment or
additional amounts any Transferee, or Lender (or Transferee) through a New
Lending Office, would be entitled to receive (without regard to this clause (i))
do not exceed the indemnity payment or additional amounts that the person making
the assignment, participation or transfer to such Transferee, or Lender (or
Transferee) making the designation of such New Lending Office, would have been
entitled to receive in the absence of such assignment, participation, transfer
or designation or (ii) the obligation to pay such additional amounts or such
indemnity payments would not have arisen but for a failure by such Non-U.S.
Lender (including any Transferee) to comply with the provisions of paragraph (g)
above and (i) below.

         (i)   Any Lender (or Transferee) claiming any indemnity payment or
additional amounts payable pursuant to this Section 2.16 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by the Borrower or to
change the jurisdiction of its applicable lending office if the making of such a
filing or change would avoid the need for or reduce the amount of any such
indemnity payment or additional amounts that may thereafter accrue and would
not, in the good faith determination of such Lender (or Transferee), be
otherwise disadvantageous to such Lender (or Transferee).

         (j)   Nothing contained in this Section 2.16 shall require any Lender
(or Transferee) or the Agent to make available to the Borrower any of its tax
returns (or any other information) that it deems to be confidential or
proprietary.

         SECTION 2.17.  Assignment of Commitments Under Certain Circumstances.

         In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.11 or 2.12, or the Borrower shall be required
to make additional payments to any Lender under Section 2.16, the Borrower shall
have the right, at its own expense, upon notice to such Lender and the Agent, to
require such Lender to transfer and assign without recourse (in accordance with
and subject to the restrictions contained in Section 8.04) all such Lender's
interests, rights and obligations contained hereunder to another financial
institution approved by the Agent and the Borrower (which approval shall not be
unreasonably withheld) which shall assume such obligations; provided that (i) no
such assignment shall conflict with any law, rule or regulation or order of any
Governmental Authority and (ii) the assignee shall pay to the affected Lender in
immediately available funds on the date of such assignment the principal of and
interest accrued to the date of payment on the Loans made by it hereunder and
all other amounts accrued for its account or owed to it hereunder and the
Borrower shall pay the processing and recordation fee due pursuant to Section
8.04.

                                  ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

                  analogous governing body of the Borrower or such Significant
                  Subsidiary, as the case may be) of such property at the time

                                    THE AGENT

         In order to expedite the transactions contemplated by this Agreement,
Citibank is hereby appointed to act as Agent on behalf of the Lenders. Each of
the Lenders hereby irrevocably authorizes the Agent to take such actions on
behalf of such Lender and to exercise such powers as are specifically delegated
to the Agent by the terms and provisions hereof, together with such actions and
powers as are reasonably incidental thereto. The Agent is hereby expressly
authorized by the Lenders, without hereby limiting any implied authority, (i) to
receive on behalf of the Lenders all payments of principal of and interest on
the Loans and all other amounts due to the Lenders hereunder, and promptly to
distribute to each Lender its proper share of each payment so received; (ii) to
give notice on behalf of each of the Lenders to the Borrower of any Event of
Default of which the Agent has actual knowledge acquired in connection with its
agency hereunder; and (iii) to distribute to each Lender copies of all notices,
financial statements and other materials delivered by the Borrower pursuant to
this Agreement as received by the Agent.

         None of the Agent or any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them
except for its or his or her own gross negligence or willful misconduct, or be
responsible for any statement, warranty or representation herein or the contents
of any document delivered in connection herewith, or be required to

<PAGE>

                                                                              40

ascertain or to make any inquiry concerning the performance or observance by the
Borrower of any of the terms, conditions, covenants or agreements contained in
this Agreement. The Agent shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements. The Agent may deem and treat the
Lender that makes any Loan as the holder of the indebtedness resulting therefrom
for all purposes hereof until it shall have received notice from such Lender,
given as provided herein, of the transfer thereof. The Agent shall in all cases
be fully protected in acting, or refraining from acting, in accordance with
written instructions signed by the Required Lenders and, except as otherwise
specifically provided herein, such instructions and any action or inaction
pursuant thereto shall be binding on all the Lenders. The Agent shall, in the
absence of knowledge to the contrary, be entitled to rely on any instrument or
document believed by it in good faith to be genuine and correct and to have been
signed or sent by the proper person or persons. None of the Agent or any of its
directors, officers, employees or agents shall have any responsibility to the
Borrower on account of the failure of or delay in performance or breach by any
Lender of any of its obligations hereunder or to any Lender on account of the
failure of or delay in performance or breach by any other Lender or the Borrower
of any of their respective obligations hereunder or in connection herewith. The
Agent may execute any and all duties hereunder by or through agents or employees
and shall be entitled to rely upon the advice of legal counsel selected by it
with respect to all matters arising hereunder and shall not be liable for any
action taken or suffered in good faith by it in accordance with the advice of
such counsel.

         The Lenders hereby acknowledge that the Agent shall not be under any
duty to take any discretionary action permitted to be taken by it pursuant to
the provisions of this Agreement unless it shall be requested in writing to do
so by the Required Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, the Agent may resign at any time by notifying the Lenders and
the Borrower. Upon any such resignation, the Required Lenders shall have the
right to appoint a successor Agent acceptable to the Borrower. If no successor
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within 30 days after the retiring Agent gives notice of its
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be a bank organized under the laws of the United
States and having a combined capital and surplus of at least $500,000,000 or an
Affiliate of any such bank. Upon the acceptance of any appointment as Agent
hereunder by a successor bank, such successor shall succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Agent and the
retiring Agent shall be discharged from its duties and obligations hereunder.
After the Agent's resignation hereunder, the provisions of this Article and
Section 8.05 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Agent.

         With respect to the Loans made by it hereunder, Citibank, in its
individual capacity and not as the Agent, shall have the same rights and powers
as any other Lender and may exercise the same as though it were not the Agent,
and the Agent and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any Subsidiary or
other Affiliate thereof as if it were not an Agent.

         Each Lender agrees (i) to reimburse the Agent, on demand, in the amount
of its pro rata share (based on its Commitment hereunder or, if the Commitments
shall have been terminated, the amount of its outstanding Loans) of any expenses
incurred for the benefit of the Lenders in its role as Agent, including counsel
fees and compensation of agents and employees paid for services rendered on
behalf of the Lenders, which shall not have been reimbursed by the Borrower and
(ii) to indemnify and hold harmless the Agent and any of its directors,
officers, employees or agents, on demand, in the amount of such pro rata share,
from and against any and all liabilities, taxes, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever that may be imposed on, incurred by or asserted
against it in any way relating to or arising out of this Agreement or any action
taken or omitted by it under this Agreement to the extent the same shall not
have been reimbursed by the Borrower; provided that no Lender shall be liable to
the Agent for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or willful misconduct of the Agent or any of its
directors, officers, employees or agents.

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

BY VIRTUE OF ITS DESIGNATION AS "JOINT LEAD ARRANGER" AND "CO-BOOK MANAGER", NOR
BANK OF AMERICA, N.A., BY VIRTUE OF ITS DESNIGATION AS "SYNDICATION AGENT",

delivered in connection with or pursuant to this Agreement shall be considered
to have been relied upon by the Lenders and shall survive the making by the
Lenders of the Loans regardless of any investigation made by the Lenders or on
their behalf, and shall continue in full force and effect as long as the

payable under this Agreement is outstanding and unpaid or the Commitments have
not been terminated.

         SECTION 8.03.  Binding Effect.

Assignment and Acceptance and (ii) record the information contained therein in
the Register.

         (f)      Each Lender may, without the consent of the Borrower or the
Agent, sell participations to one or more banks or other entities in all or a
portion of its rights and/or obligations under this Agreement (including all or
a portion of its Commitment and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) each participating bank or other entity
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.11, 2.16 and 8.05 to the same extent as if it were the selling Lender
(and limited to the amount that could have been claimed by the selling Lender
had it continued to hold the interest of such participating bank or other
entity), except that all claims made pursuant to such Sections shall be made
through such selling Lender, and (iv) the Borrower, the Agent and the other
Lenders shall continue to deal solely and directly with such selling Lender in
connection with such Lender's rights and obligations under this Agreement, and
such Lender shall retain the sole right to enforce the obligations of the
Borrower under this Agreement and to approve any amendment, modification or
waiver of any provision of this Agreement (other than amendments, modifications
or waivers (x) decreasing any fees payable hereunder or the amount of principal
of, or the rate at which interest is payable on, the Loans or (y) extending any
scheduled principal payment date or date fixed for the payment of interest on
the Loans).

         (g)      Any Lender or participant may, in connection with any
assignment or participation or proposed assignment or participation pursuant to
this Section, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure, each
such assignee or participant or proposed assignee or participant shall execute
an agreement whereby such assignee or participant shall agree (subject to
customary exceptions) to preserve the confidentiality of any such information.

         (h)      The Borrower shall not assign or delegate any rights and
duties hereunder without the prior written consent of all Lenders, and any
attempted assignment or delegation (except as a consequence of a transaction
expressly permitted under Section 5.09) by the Borrower without such consent
shall be void.

         (i)      Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute any
such Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, the Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes evidencing the Loans made to the Borrower by the assigning Lender
hereunder.

         SECTION 8.05.  Expenses; Indemnity.

         (a)      The Borrower agrees to pay all reasonable out-of-pocket
expenses (including reasonable fees, charges and disbursements of counsel)
incurred by the Agent in connection with entering into this Agreement or in
connection with any amendments, modifications or waivers of the provisions
hereof (but only if such amendments, modifications or waivers are requested by
the Borrower) (whether or not the transactions hereby contemplated are
consummated), or incurred by the Agent or any Lender in connection with the
enforcement of its rights in connection with this Agreement or in connection
with the Loans made hereunder, including the reasonable fees and disbursements
of counsel for the Agent and, in the case of enforcement following an Event of
Default, the Lenders.

         (b)      The Borrower agrees to indemnify each Lender against any loss,
calculated in accordance with the next sentence, or reasonable expense which
such Lender may sustain or incur as a consequence of (i) any failure by the
Borrower to borrow or to refinance, convert or continue any Loan hereunder
(including as a result of the Borrower's failure to fulfill any of the
applicable conditions set forth in Article IV) after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03, (ii) any assignment of a Eurodollar Loan required by the Borrower
or payment, prepayment or conversion of a Eurodollar Loan required by any
provision of this Agreement or otherwise made or deemed made on a date other
than the last day of the Interest Period, if any, applicable thereto, (iii) any
default in payment or prepayment of the principal amount of any Loan or any part
thereof or interest accrued thereon, as and when due and payable (at the due
date thereof, whether by scheduled maturity, acceleration, irrevocable notice of
prepayment or otherwise) or (iv) the occurrence of any Event of Default,
including, in each such case, any loss or reasonable expense sustained or
incurred or to be sustained or incurred by such Lender in liquidating or
employing deposits from third parties, or with respect to commitments made or
obligations undertaken with third parties, to effect or maintain any Loan
hereunder or any part thereof as a Eurodollar Loan. Such loss shall include an
amount equal to the excess, if any, as reasonably determined by such Lender, of
(x) its cost of obtaining the funds for the Loan being paid, prepaid,
refinanced, converted or not borrowed (assumed to be the LIBO Rate) for the
period from the date of such payment, prepayment, refinancing or failure to
borrow or refinance to the last day of the Interest Period for such Loan (or, in
the case of a failure to borrow or refinance the Interest Period for such Loan
which would have commenced on the date of such failure) over (y) the amount of
interest (as reasonably determined by such Lender) that would be realized by
such Lender in reemploying the funds so paid, prepaid or not borrowed or
refinanced for such period or Interest Period, as the case may be.

         (c)      The Borrower agrees to indemnify the Agent, the Joint Lead
Arrangers, each Lender, each of their Affiliates and the directors, officers,
employees and agents of the foregoing (each such person being called an
"Indemnitee") against, and to hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including reasonable
counsel fees and expenses, incurred by or asserted against any Indemnitee
arising out of (i) the use of the proceeds of the Loans, (ii) the preparation,
execution, delivery, enforcement, performance and administration of this
Agreement or (iii) any claim, litigation, investigation or proceeding relating
to any of the foregoing, whether or not any Indemnitee is a party thereto,
including any of the foregoing arising from the negligence, whether sole or
concurrent, on the

<PAGE>

                                                                              46

part of any Indemnitee; provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses (A) are determined by a final judgment of a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (B) result from any litigation brought
by such Indemnitee against the Borrower or by the Borrower against such
Indemnitee, in which a final, nonappealable judgment has been rendered against
such Indemnitee; provided, further, that the Borrower agrees that it will not,
nor will it permit any Subsidiary to, without the prior written consent of each
Indemnitee, settle, compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification could be sought under the indemnification provisions of this
Section 8.05(c) (whether or not any Indemnitee is an actual or potential party
to such claim, action, suit or proceeding), unless such settlement, compromise
or consent does not include any statement as to an admission of fault,
culpability or failure to act by or on behalf of any Indemnitee and does not
involve any payment of money or other value by any Indemnitee or any injunctive
relief or factual findings or stipulations binding on any Indemnitee.

         (d)      The provisions of this Section shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any investigation made by or on behalf of the
Agent or any Lender.  All amounts due under this Section shall be payable on
written demand therefor.

         (e)      A certificate of any Lender or the Agent setting forth any
amount or amounts which such Lender or the Agent is entitled to receive pursuant
to paragraph (b) of this Section and containing an explanation in reasonable
detail of the manner in which such amount or amounts shall have been determined
shall be delivered to the Borrower and shall be conclusive absent manifest
error.

         SECTION 8.06.  Right of Setoff.

         If an Event of Default shall have occurred and be continuing, each
Lender is hereby authorized at any time and from time to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower
now or hereafter existing under this Agreement held by such Lender, irrespective
of whether or not such Lender shall have made any demand under this Agreement
and although such obligations may be unmatured. The rights of each Lender under
this Section are in addition to other rights and remedies (including other
rights of setoff) which such Lender may have.

         SECTION 8.07.  Applicable Law.

         THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK.

<PAGE>

                                                                              47

         SECTION 8.08.  Waivers; Amendment.

         (a)      No failure or delay of the Agent or any Lender in exercising
any power or right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies which they would otherwise have. No waiver
of any provision of this Agreement or consent to any departure therefrom shall
in any event be effective unless the same shall be permitted by paragraph (b)
below, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. No notice or demand on the
Borrower or any Subsidiary in any case shall entitle such party to any other or
further notice or demand in similar or other circumstances.

         (b)      Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan or the date for the payment of any Commitment Fee, or
waive or excuse any such payment or any part thereof, or decrease the rate of
interest on any Loan, without the prior written consent of each Lender affected
thereby, (ii) increase the Commitment of any Lender, decrease the Commitment Fee
of any Lender without the prior written consent of such Lender, or (iii) amend
or modify the provisions of Section 2.13, 2.14 or Section 8.04(h), the
provisions of this Section or the definition of the "Required Lenders", without
the prior written consent of each Lender; provided further, however, that no
such agreement shall amend, modify or otherwise affect the rights or duties of
the Agent hereunder without the prior written consent of the Agent. Each Lender
shall be bound by any waiver, amendment or modification authorized by this
Section and any consent by any Lender or the Agent pursuant to this Section
shall bind any assignee of its rights and interests hereunder.

         SECTION 8.09.  Entire Agreement.

         This Agreement (including the schedules and exhibits hereto) and the
Letter Agreement represent the entire contract among the parties relative to the
subject matter hereof and thereof. Any previous agreement, whether written or
oral, among the parties with respect to the subject matter hereof, is superseded
by this Agreement and the Letter Agreement. There are no unwritten oral
agreements between the parties. Nothing in this Agreement, expressed or implied,
is intended to confer upon any party other than the parties hereto any rights,
remedies, obligations or liabilities under or by reason of this Agreement.

         SECTION 8.10.  Severability.

         In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby. The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or

<PAGE>

                                                                              48

unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         SECTION 8.11.  Counterparts.

         This Agreement may be executed in two or more counterparts, each of
which shall constitute an original but all of which when taken together shall
constitute but one contract, and shall become effective as provided in Section
8.03.

         SECTION 8.12.  Headings.

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

         SECTION 8.13.  Interest Rate Limitation.

         (a)      Notwithstanding anything herein to the contrary, if at any
time the applicable interest rate, together with all fees and charges which are
treated as interest under applicable law (collectively the "Charges"), as
provided for herein or in any other document executed in connection herewith, or
otherwise contracted for, charged, received, taken or reserved by any Lender,
shall exceed the maximum lawful rate (the "Maximum Rate") which may be
contracted for, charged, taken, received or reserved by such Lender in
accordance with applicable law, the rate of interest payable on the Loans of
such Lender, together with all Charges payable to such Lender, shall be limited
to the Maximum Rate.

         (b)      If the amount of interest, together with all Charges, payable
for the account of any Lender in respect of any interest computation period is
reduced pursuant to paragraph (a) of this Section and the amount of interest,
together with all Charges, payable for such Lender's account in respect of any
subsequent interest computation period, computed pursuant to Section 2.06, would
be less than the Maximum Rate, then the amount of interest, together with all
Charges, payable for such Lender's account in respect of such subsequent
interest computation period shall, to the extent permitted by applicable law, be
automatically increased to such Maximum Rate; provided that at no time shall the
aggregate amount by which interest paid for the account of any Lender has been
increased pursuant to this paragraph (b) exceed the aggregate amount by which
interest, together with all Charges, paid for its account has theretofore been
reduced pursuant to paragraph (a) of this Section.

         SECTION 8.14.  Jurisdiction; Venue.

         (a)      The Borrower hereby irrevocably and unconditionally submits,
for itself and its property, to the nonexclusive jurisdiction of any New York
State court or Federal court of the United States of America sitting in New York
City, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement, or for recognition or enforcement
of any judgment, and each of the parties hereto hereby irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be

<PAGE>

                                                                              49

conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.  Subject to the foregoing and to paragraph
(b) below, nothing in this Agreement shall affect any right that any party
hereto may otherwise have to bring any action or proceeding relating to this
Agreement against any other party hereto in the courts of any jurisdiction.

         (b)      The Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or thereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any New York State
court or Federal court of the United States of America sitting in New York City.
Each of the parties hereto hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

         SECTION 8.15.  Confidentiality.

         Each Lender shall use its best efforts to hold in confidence all
information, memoranda, or extracts furnished to such Lender (directly or
through the Agent) by the Borrower hereunder or in connection with the
negotiation hereof; provided that such Lender may disclose any such information,
memoranda or extracts (i) to its Affiliates, accountants or counsel, (ii) to any
regulatory agency having authority to examine such Lender, (iii) as required by
any legal or governmental process or otherwise by law, (iv) except as provided
in the last sentence of Section 5.03, to any person to which such Lender sells
or proposes to sell an assignment or a participation in its Loans hereunder, if
such other person agrees for the benefit of the Borrower to comply with the
provisions of this Section and (v) to the extent that such information,
memoranda or extracts shall be publicly available or shall have become known to
such Lender independently of any disclosure by the Borrower hereunder or in
connection with the negotiation hereof. Notwithstanding the foregoing, any
Lender may disclose the provisions of this Agreement and the amounts, maturities
and interest rates of its Loans to any purchaser or potential purchaser of such
Lender's interest in any Loan.

RECITALS:

WHEREAS, the Borrower, the Custodian and the Lender entered into a Credit
Agreement dated as of August 23, 2001, as amended by Amendment No. 1 made as of
November 12, 2001 (collectively, the "Credit Agreement"); and

WHEREAS, the parties desire to amend the Credit Agreement as provided herein;

NOW, THEREFORE, for good and valuable consideration (the receipt and sufficiency
of which are hereby acknowledged by each of the parties hereto), the parties
hereto hereby agree as follows:

1.   Defined Terms.

     In this Amendment, unless something in the subject matter or the context is
inconsistent therewith, capitalized terms used and not otherwise defined herein
shall have the respective meanings attributed to such terms in Schedule A to the
Credit Agreement.

2.   Amendments to Credit Agreement.

     (a)  Section 2.4.2(b)(iii) of the Credit Agreement is hereby deleted in its
entirety, and the following language is inserted in lieu thereof:

<PAGE>

                                      -2-

         (iii)   results in there being no Excess Advances (based on a
                 Receivables Borrowing Base taking into account such
                 Receivables).

    (b)  Section 3.1.1 of the credit Agreement is hereby deleted in its entirety
and the following is inserted in lieu thereof:

         3.1.1   Each Advance shall bear interest in Canadian Dollars during
                 each Interest Period applicable thereto, on the outstanding
                 amount of such Advance, at a rate per annual equal to the CDOR
                 for such Interest Period plus 1.25% per annum; provided that in
                 the case of an Advance or a portion thereof which when added to
                 all outstanding Advances made on a date prior to such Advance
                 results in the aggregate of all Advances exceeding
                 $150,000,000, the rate per annum applicable to such Advance or
                 such portion thereof, as the case may be, shall be the CDOR for
                 such Interest Period plus 1.50% per annum.

    (c)  Article 3 of the Credit Agreement is hereby amended by adding the
following thereto:

         3.7     Non-Utilization Fee

                 The Borrower shall pay in respect of each Interest Period a fee
                 (the "Non-Utilization Fee") equal to 20 basis points multiplied
                 by the number of days in the Interest Period divided by 365 on
                 the positive difference, if any, between (i) the Credit
                 Facility Limit and (ii) the average daily (as calculated at the
                 close of business on each day) sum of the aggregate outstanding
                 Advances during such Interest Period. The Non-Utilization Fee
                 for an Interest Period shall be paid on the Payment Date
                 immediately following such Interest Period.

         3.8     Maturity Date Extension

         3.8.1   The Lender may extend the existing Maturity Date to August 22,
                 2003 by giving written notice to that effect to the Borrower on
                 or prior to July 22, 2002.

         3.8.2   If the Lender is willing to extend the existing Maturity Date
                 pursuant to Section 3.8.1, the Borrower shall pay to the Lender
                 on August 22, 2002 an extension fee (an "Extension Fee") of
                 $250,000.

         3.8.3   If the Lender is willing to extend the existing Maturity Date
                 pursuant to Section 3.8.1 and the Borrower is not, the Borrower
                 shall pay to the Lender on August 22, 2002, the Extension Fee
                 of $250,000 and the facility will terminate on the existing
                 Maturity Date.

         3.8.4   The Borrower agrees with the Lender that (i) an Extension Fee
                 shall be conclusively deemed to have been fully earned on the
                 date on which the Lender offers to extend the existing Maturity
                 Date and, once paid, shall

<PAGE>

                                      -3-

                 not be refundable in whole or in part in any circumstances, and
                 (ii) payment of an Extension Fee shall not constitute or give
                 rise to any obligation on the part of the Lender to make any
                 Advance under this Agreement, other than in accordance with the
                 terms of this Agreement.

     (d) The definition of "Advance Rate" in Schedule A to the Credit Agreement
is hereby deleted in its entirety, and the following is inserted in lieu
thereof:

         "Advance Rate" means (i) prior to the occurrence of a Step-Up Trigger
         Event, (A) 70%, in the case of Eligible Receivables which Contracts
         form part of the Collateral (including those to be added to the
         Collateral pursuant to a Drawdown Notice), provide for more than 60
         monthly payments and result in the number of such Contracts exceeding
         25% (in terms of outstanding balance) of all Contracts forming part of
         the Collateral; and (B) otherwise, 75%; or (ii) 70% from and after the
         occurrence of a Step-Up Trigger Event.

     (e) The definition of "Credit Facility Limit" in Schedule A to the Credit
Agreement is hereby deleted in its entirety, and the following is inserted in
