                  CREDIT AGREEMENT (this "Agreement"), dated as of April 26,
                  2004, among TXU Corp., a Texas corporation (the "Borrower"),
                  the lenders listed in Schedule 2.01 (together with their
                  successors and assigns, the "Lenders"), and Credit Suisse
                  First Boston (together with its successors, "CSFB"), 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 CSFB has agreed to act as administrative agent for the Lenders, on such
terms and conditions;

         Accordingly, the parties hereto agree as follows:

                            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 2.07 or 2.11(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 any
         outstanding class of 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).

                  "Administrative Questionnaire" means an Administrative
         Questionnaire in the form of Exhibit C.

                  "Affiliate" shall mean, when used with respect to a specified

         controlled by or is under common control with the person specified.

                                                                               2



                  "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
         announced from time to time by CSFB as its prime 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,
         as determined by CSFB, of the quotations for the day of such
         transactions received by CSFB from three Federal funds brokers of
         recognized standing selected by it. If for any reason CSFB shall have
         determined (which determination shall be conclusive absent manifest
         error; provided that CSFB 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 CSFB 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 ABR Loan 0% per annum
         and for any Eurodollar Loan 0.875% per annum, provided, however, at any
         time an Event of Default has occurred and is continuing, the Applicable
         Margins set forth herein shall be increased by 2.00%.

                  "Assignment and Assumption" shall mean an assignment and
         assumption entered into by a Lender and an assignee in the form of
         Exhibit B.

         in Section 2.01.

                  "Available Commitment" shall mean, for each Lender, the excess
         of such Lender's Commitment over the Loans made by such Lender.
         "Available Commitments" shall refer to the aggregate of the Lenders'
         Available Commitments hereunder.

                  "Board" shall mean the Board of Governors of the Federal
         Reserve System of the United States.

                  "Board of Directors" shall mean the board of directors of the
         Borrower or any duly authorized committee thereof.

                  "Borrower" shall have the meaning given such term in the

                  "Borrowing" shall mean a group of Loans of a single Type made

         shall also exclude any day on which banks are not open for dealings in
         dollar deposits in the London interbank market.

                  "a Change in Control" shall be deemed to have occurred if (i)
         any person or "group" (within the meaning of Section 13(d) or 14(d) of
         the Exchange Act, as amended) shall acquire beneficial ownership of
         more than 30% of any outstanding class of Voting Shares of TXU unless

         hereto to make Loans, as such Commitment may be permanently terminated
         or reduced from time to time pursuant to Section 2.08 or modified from
         time to time pursuant to Section 8.04. The Commitment of each Lender

require, any pronoun shall include the corresponding masculine, feminine and
neuter forms. The words "include," "includes" and "including" shall be deemed to
be followed by the phrase "without limitation." All references herein to
Articles, Sections, Exhibits and Schedules shall be deemed references to
Articles and Sections of, and Exhibits and Schedules to, this Agreement unless
the context shall otherwise require. Except as otherwise expressly provided
herein, all terms of an accounting or financial nature shall be construed in
accordance with GAAP, as in effect from time to time; provided, however, that
for purposes of determining compliance with any covenant set forth in Article V,
such terms shall be construed in accordance with GAAP as in effect on the date
hereof applied on a basis consistent with the application used in preparing the

                                   ARTICLE II

         SECTION 2.01.  Commitments.

representations and warranties herein set forth, each Lender agrees, severally
and not jointly, to make Loans to the Borrower at any time and from time to time

Borrower exceed the Total Commitment. Within the foregoing limits, the Borrower
may borrow, pay or prepay Loans pursuant to Section 2.09 on and after the date
hereof and prior to the Maturity Date subject to the terms, conditions and
limitations set forth herein, provided, however, that once any amount is repaid

prepayments under Section 2.02(d)), such amount may not be reborrowed by the
Borrower.

                                                                              15



         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 $25,000,000 (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 2.12. Unless the Agent shall have 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 2.09, as applicable, with the proceeds of a new Borrowing, and

<PAGE>
                                                                              16



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, (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, and (iii) in the case of the initial Borrowing, not later
than 3:00 p.m., New York City time, on the day of 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, (C) if such Borrowing is to be a Eurodollar Borrowing, the Interest
Period with respect thereto, which shall not end after the Maturity Date, and
(D) the location and number of the Borrower's account to which funds are to be
disbursed, which shall comply with the requirements of this Agreement. If no
election as to the Type of Borrowing is specified in any such notice, then the
requested Borrowing shall be deemed 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 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.

         SECTION 2.04.  Fees.

         (a) The Borrower agrees to pay to each Lender, through the Agent, on
each last day of the month following March 31, June 30, September 30 and
December 31 (with the first payment being due on April 30, 2004) 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 Commitment Fee Percentage from time to time in effect on the
unused portion of the 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 the fees from time to time
payable to it in its capacity as Agent pursuant to the Letter Agreements (the
"Administrative Fees").
<PAGE>
                                                                              17



         (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 outstanding Loans in
accordance with their terms.

         SECTION 2.06.  Interest on Loans.

         (a) The Loans comprising each Eurodollar Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a 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) 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 CSFB,
and such determination shall be conclusive absent manifest error, provided that
CSFB shall, upon request, provide to the Borrower a certificate setting forth
in reasonable detail the basis for such determination.
<PAGE>
                                                                              18



         SECTION 2.07.  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 2.08.  Termination and Reduction of Commitments.

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

         (b) On each day following the last day of the Availability Period on
which the Total Commitment shall exceed the aggregate principal amount of Loans
outstanding, the Total Commitment shall automatically reduce by an amount equal
to such excess.

         (c) 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 in a minimum principal amount 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 amount of
outstanding Loans on the date of such termination or reduction (after giving
effect to any prepayment made pursuant to Section 2.09) 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 2.08(c) and of each Lender's
portion of any such termination or reduction of the Total Commitment.

         (d) 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 2.09.  Prepayment.

         (a) Optional. 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 $10,000,000 and not less than $10,000,000. 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.

         (b) Mandatory. On the date of receipt by (i) or on behalf of the
Borrower of any Net Cash Proceeds, (ii) TXU Australia or any other person of any
TXU Australia Net Cash Proceeds, (iii) TXU Energy or any other person of any
TXU Energy Net Cash Proceeds, or (iv) TXU Gas or any other person of any TXU Gas
Proceeds, the Borrower shall prepay the Loans, in an amount equal to the
Mandatory Prepayment Amount, together with accrued interest on such Loans to the
date of such prepayment on the principal amount prepaid.

         (c) All prepayments under this Section 2.09 shall be subject to Section
8.05 but otherwise without premium or penalty. All prepayments under this
Section 2.09 shall be accompanied by accrued interest on the principal amount
being prepaid to the date of payment.

         SECTION 2.10. 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 (as the case may be) or its lending office imposed by the
jurisdiction in which such Lender's principal executive office or 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 Loan (other than an ABR 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 outstanding Loans (other than an ABR 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 2.10(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

                                                                              20



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 to such Lender by the
Borrower. It is acknowledged that this Agreement is being entered into by the
Lenders on the understanding that the Lenders will not be required to maintain
capital against their Commitments under currently applicable laws, regulations
and regulatory guidelines. In the event the Lenders shall otherwise determine
that such understanding is incorrect, it is agreed that the Lenders, will be
entitled to make claims under this paragraph (b) based upon market requirements
prevailing on the date hereof for commitments under comparable credit facilities
against which capital is required to be maintained.

         (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, as the case may be, 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 2.10 for any costs incurred or reductions
suffered with respect 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.
<PAGE>
                                                                              21



         (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 2.11.  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 which would otherwise have been applied to
repay the Eurodollar Loans that 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 2.11, 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 2.12.  Pro Rata Treatment.

         Except as required under Sections 2.11 and 2.16, 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
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 2.13.   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

<PAGE>
                                                                              22


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 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 2.13 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 2.14.   Payments.

         (a) The Borrower shall make each payment (including principal of or
interest on any outstanding Loans 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 Eleven Madison
Avenue, New York, New York 10010-3629, in immediately available funds as
instructed from time to time by the Agent. 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
outstanding Loans 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.

         SECTION 2.15.   Taxes.

         (a) Any and all payments of principal and interest on any of the
outstanding Loans, or of any Fees or indemnity or expense reimbursements by the
Borrower hereunder ("Borrower Payments") shall be made, in accordance with
Section 2.14, 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 the
Borrower Payments, but only to the extent reasonably attributable to the

<PAGE>
                                                                              23


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 amounts payable under this
Section 2.15) 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 Agreements ("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 person, 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 their behalf, 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 any 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 2.15, 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 Borrower's expense. If any 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 2.15, 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 2.15 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

<PAGE>
                                                                              24


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 2.15 shall
survive the payment in full of the principal of and interest on all outstanding
Loans hereunder.

         (g) Each of the Agent and 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" or "Non U.S. Agent", as
applicable) 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 2.15(g), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.15(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
or Non-U.S. Agent (including any Transferee), or to pay any additional amounts
to any Non-U.S. Lender or Non-U.S. Agent (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 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 any 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,

<PAGE>
                                                                              25


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 2.15 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 2.15 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 2.16.  Assignment of Commitments Under Certain Circumstances.

         In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.10 or 2.11, or the Borrower shall be required
to make additional payments to any Lender under Section 2.15, 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

of its Subsidiaries, (y) any order of any Governmental Authority or (z) any
provision of any indenture, agreement or other instrument to which the Borrower

                (iii)  any extension, renewal or refunding of any mortgage,
         pledge, security interest,  lien or  encumbrance  permitted  by
         paragraph (i) or (ii)  above on capital stock of any Subsidiary
         theretofore subject thereto (or  substantially the same capital stock)
         or any portion thereof; or

                (iv)   any judgment,  levy, execution,  attachment or other
         similar lien upon such capital stock arising in connection with court
         proceedings,  provided that either

                     (A) the execution or enforcement  of each such lien is
                effectively  stayed within 30 days after entry of the
                corresponding  judgment (or the corresponding judgment has
                been  discharged  within such 30 day period) and the claims
                secured thereby are being  contested  in good faith by
                appropriate  proceedings  timely commenced and diligently
                prosecuted;

                     (B) the payment of each such lien is covered in full by
                insurance and the insurance company has not denied or contested
                coverage thereof; or

                     (C) so long as each such lien is adequately bonded, any
                appropriate legal proceedings that may have been duly
                initiated for the review of the corresponding judgment, decree
                or order shall not have been fully terminated or the period
                within which such proceedings may be initiated shall not have
                expired.

         For purposes of this Section 5.11, "Indebtedness" means all
indebtedness, whether or not represented by bonds, debentures, notes or other
securities, created or assumed by the Borrower for the repayment of money
borrowed. All indebtedness for money borrowed secured by a lien upon property
owned by the Borrower and upon which indebtedness for money borrowed the
Borrower customarily pays interest, although the Borrower has not assumed or
become liable for the payment of such indebtedness for money borrowed, shall for
purposes of this Section 5.10 be deemed to be Indebtedness of the Borrower. All
indebtedness of others for money borrowed that is guaranteed as to payment of
principal by the Borrower or in effect guaranteed by the Borrower through a
contingent agreement to purchase such indebtedness for money borrowed shall for
purposes of this Section 5.11 be deemed to be Indebtedness of the Borrower, but
no other contingent obligation of the Borrower in respect of indebtedness for
money borrowed or other obligations incurred by others shall for purposes of
this Section 5.10 be deemed to be Indebtedness of the Borrower.

                                                                              36



         In case the Borrower shall propose to pledge, mortgage, hypothecate or
grant a security interest in any capital stock of any Subsidiary owned by the
Borrower to secure any Indebtedness, other than as permitted by subsections
(a)(i) through (a)(ii), inclusive, of this Section 5.11, the Borrower will prior
thereto give written notice thereof to the Lender, and the Borrower will prior
to or simultaneously with such pledge, mortgage, hypothecation or grant of
security interest, effectively secure (for so long as such other Indebtedness
shall be so secured), in form satisfactory to the Lender, all the Commitments
and the outstanding Loans equally and ratably with such Indebtedness and with
any other indebtedness for money borrowed similarly entitled to be equally and
ratably secured.

         (b) The  provisions of subsection  (a) of this Section 5.10 shall not
apply in the event that the Borrower  shall pledge,  mortgage,  hypothecate or
grant a security  interest in or other lien upon any capital stock of any
Subsidiary now or  hereafter  owned by the  Borrower  to secure  any
Indebtedness  that  would otherwise be subject to the  foregoing  restriction
up to an  aggregate  amount that,  together  with all other  Indebtedness
(other than  mortgages,  pledges, security  interests,  liens or encumbrances
permitted by subsection (a) of this Section  5.11) which would  otherwise be
subject to the  foregoing  restriction, does not at the time exceed 5% of
Consolidated Capitalization.

         (c)      For purposes of this Section 5.11:

                (i)      The term "Consolidated Capitalization" means the sum
         obtained by adding (i) Total Consolidated Shareholders' Equity, (ii)
         Consolidated Indebtedness for money borrowed (exclusive of any thereof
         which is due and payable within one year of the date such sum is
         determined) and, without duplication, (iii) any preference or
         preferred stock of the Borrower or any Consolidated Subsidiary that is
         subject to mandatory redemption or sinking fund provisions.

                (ii)     The term "Total Consolidated  Shareholders'  Equity"
         means the total Assets of the Borrower and its Consolidated
         Subsidiaries less all liabilities of the Borrower and its Consolidated
         Subsidiaries.  As used in this definition,  "liabilities" means all
         obligations  that would,  in accordance with generally  accepted
         accounting  principles,  be classified on a balance sheet as
         liabilities,  including without  limitation,  (i) indebtedness
         secured by property of the Borrower or any of its Consolidated
         Subsidiaries  whether or not the Borrower or such  Consolidated
         Subsidiary is liable for the payment thereof  unless,  in the case
         that the  Borrower or such  Consolidated  Subsidiary  is not so
         liable,  such  property has not been  included  among the
         Assets of the Borrower or such Consolidated  Subsidiary on such
         balance sheet, (ii) deferred  liabilities,  (iii) indebtedness
         of the Borrower or any of its  Consolidated  Subsidiaries  that is
         expressly  subordinated in right and priority of payment to
         other  liabilities  of the  Borrower or such  Consolidated
         Subsidiary.  As used in this  definition,  "liabilities"  includes
         preference or preferred  stock of the Borrower or any  Consolidated
         Subsidiary  only to the extent of any such  preference or
         preferred stock that is subject to mandatory redemption or sinking
         fund provisions.

                (iii)    The "Assets" of any person means the whole or any
         part of its business, property, assets, cash and receivables.

                (iv)     The term "Consolidated Indebtedness" means total
         indebtedness as shown on the consolidated balance sheet of the
         Borrower and its Consolidated Subsidiaries.

         SECTION 5.12.  Interest Coverage.

         It will not, as of the end of each quarter of each fiscal year of the
Borrower, permit the ratio of EBITDA to Interest Expense for the twelve months
then ended to be less than or equal to 150%.

         SECTION 5.13.  Equity Capitalization Ratio.

         It will not, as of the end of each quarter of each fiscal year of the
Borrower, permit the ratio of Consolidated Shareholders' Equity to Consolidated
Total Capitalization to be less than 35%.

         SECTION 5.14.  Restrictive Agreements.

         The Borrower will not permit TXU Energy or Oncor to enter into any
agreement restricting the ability of TXU Energy or Oncor to make payments,
directly or indirectly, to its shareholders by way of dividends, advances,
repayments of loans or advances, reimbursements of management and other
intercompany charges, expenses and accruals or other returns on investments or
any other agreement or arrangement that restricts the ability of TXU Energy or
Oncor to make any payment, directly or indirectly, to its shareholders, other
than pursuant to the terms of preferred stock or Equity-Credit Preferred
Securities issued by TXU Energy or Oncor or any of their respective
Subsidiaries, if the effect of such agreement is to subject TXU Energy or Oncor
or any of their respective Subsidiaries to restrictions on such payments greater
than those to which such Subsidiary was subject on July 31, 2002. All such
agreements to which TXU Energy or Oncor is a party as of the date hereof are
listed in Schedule 5.14 hereto.

                                   ARTICLE VI

for a period of five days;

subject to any applicable grace periods, or (ii) fail to observe or perform any
other term, covenant, condition or agreement contained in any agreement or
instrument evidencing or governing any such Indebtedness if the effect of any
failure referred to in this clause (ii) is to cause, or to permit the holder or

Indebtedness to become due prior to its stated maturity;

         (h) an involuntary proceeding shall be commenced or an involuntary
petition shall be filed in a court of competent jurisdiction seeking (i) relief
in respect of the Borrower or any Significant Subsidiary, or of a substantial

                                   ARTICLE VII
                                    THE AGENT

         (a) In order to expedite the transactions contemplated by this
Agreement, CSFB is hereby appointed to act as Agent on behalf of the Lenders.
Each Lender 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 and all payments of principal of and
interest on the outstanding 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 Lender 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.

         (b) Neither the Agent nor any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them

<PAGE>
                                                                              40



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 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. Neither the Agent nor 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.

         (c) 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.

         (d) 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, 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 the Agent.

         (e) The Lenders may remove the Agent upon 30 days' prior notice by so
notifying the Borrower and, in such event, the Lenders shall appoint a
successor Agent acceptable to the Borrower. Either the Required Lenders or the
Borrower may remove any Agent if (i) such Agent is adjudged bankrupt or
insolvent or (ii) a receiver or other public officer takes charge of such Agent
or its property. If no successor Agent shall have been appointed by the Lenders

<PAGE>
                                                                              41



and shall have accepted such appointment within 30 days after delivery by the
Lenders of the notice required by the first sentence of this paragraph (b), the
Required Lenders or the Borrower may petition any court of competent
jurisdiction for the appointment of a successor Agent. After the Agent's
removal 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.

         (f) With respect to the Loans made by it hereunder, the Agent, in its
individual capacity and not as 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 Agent.

         (g) 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 percentage of
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 which 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 agrees that any
allocation made in good faith by the Agent of expenses or other amounts
referred to in this paragraph shall be conclusive and binding for all purposes.

         (h) 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.

         (i) CSFB, by virtue of its designation as "Sole Lead Arranger and
Bookrunner" on the cover page of this Agreement shall have no duties,
liabilities, obligations or responsibilities under this Agreement other than
as the Agent and a Lender hereunder.

         This Agreement shall become effective when it shall have been executed
by the Borrower and the Agent and when the Agent shall have received copies
hereof (telecopied or otherwise) which, when taken together, bear the signature
of each Lender, and thereafter shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns, except that the
Borrower shall not have the right to assign any rights hereunder or any interest
herein without the prior consent of all the Lenders.

         SECTION 8.04.  Successors and Assigns.

         (a) Whenever in this Agreement any of the parties hereto is referred
to, such reference shall be deemed to include the successors and assigns of
such party; and all covenants, promises and agreements by or on behalf of any
party that are contained in this Agreement shall bind and inure to the benefit
of its successors and assigns.

         (b) Each Lender may assign to one or more assignees all or a portion
of its interests, rights and obligations under this Agreement (including all or
 a portion of its Commitment and its outstanding Loans); provided, however, that
(i) except in the case of an assignment to a Lender or an Affiliate of such
Lender, an assignment to a Federal Reserve Bank or an assignment made at any
time an Event of Default shall have occurred and be continuing, the Borrower and
the Agent must give their prior written consent to such assignment (which
consent shall not be unreasonably withheld), (ii) the amount of the Commitment
of the assigning Lender subject to each such assignment (determined as of the
date the Assignment and Assumption with respect to such assignment is delivered
to the Agent) shall not be less than $1,000,000 (or, if less, the entire
remaining amount of such Lender's Commitment) and shall be in an amount that is
an integral multiple of $1,000,000 (or the entire remaining amount of such
Lender's Commitment ), (iii) the parties to each such assignment shall execute
and deliver to the Agent an Assignment and Assumption (such Assignment and
Assumption to be (A) electronically executed and delivered to the Agent via an
electronic settlement system then acceptable to the Agent, which shall initially
be the settlement system of ClearPar, LLC, or (B) manually executed and
delivered together with a processing and recordation fee of $3,500) and (iv) the
assignee, if it shall not be a Lender immediately prior to the assignment, shall
deliver to the agent an Administrative Questionnaire and applicable tax form(s).
Upon acceptance and recording pursuant to Section 8.04(e), from and after the
effective date specified in each Assignment and Assumption (A) the assignee
thereunder shall be a party hereto and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender
under this Agreement and (B) the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto (but shall continue to be entitled to the benefits of Sections 2.10, 2.15
and 8.05 as well as to any Fees accrued for its account hereunder and not yet
paid)).

         (c) By executing and delivering an Assignment and Assumption, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:

<PAGE>
                                                                              44



(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim; (ii)
except as set forth in (i) above, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto or the financial condition of the Borrower or the performance or
observance by the Borrower of any obligations under this Agreement or any other
instrument or document furnished pursuant hereto; (iii) such assignor and such
assignee represents and warrants that it is legally authorized to enter into
such Assignment and Assumption; (iv) such assignee confirms that it has received
a copy of this Agreement, together with copies of the most recent financial
statements delivered pursuant to Section 5.03 and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Assumption; (v) such assignee will
independently and without reliance upon the Agent, such assigning Lender 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 decisions in taking or
not taking action under this Agreement; (vi) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all the obligations that by the terms of this Agreement are required to be
performed by it as a Lender.

         (d) The Agent, acting for this purpose as an agent of the Borrower,
shall maintain at one of its offices in the City of New York a copy of each
Assignment and Assumption delivered to it and a register for the recordation of
the names and addresses of the Lenders, and the Commitment of, and the principal
amount of the outstanding Loans of, each Lender pursuant to the terms hereof
from time to time (the "Register"). The entries in the Register shall be
conclusive in the absence of manifest error and the Borrower, the Agent and the
Lenders may treat each person whose name is recorded in the Register pursuant
to the terms hereof as a Lender hereunder for all purposes of this Agreement.
The Register shall be available for inspection by each party hereto, at any
reasonable time and from time to time upon reasonable prior notice.

         (e) Upon its receipt of a duly completed Assignment and Assumption
executed by an assigning Lender and an assignee, an Administrative Questionnaire
and, if necessary, applicable tax form(s) completed in respect of the assignee
(unless the assignee shall already be a Lender hereunder), the written consent
of the Agent to such assignment, and the processing and recordation fee
referred to in paragraph (b) above and, if required, the written consent of the
Borrower and the Agent to such assignment, the Agent shall (i) accept such
Assignment and Assumption and (ii) record the information contained therein in
the Register. No assignment shall be effective unless it has been recorded in
the Register as provided in this paragraph (e).

         (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 its Loans); provided, however, that (i) such
Lender's obligations under this Agreement shall remain unchanged, (ii) such

<PAGE>
                                                                              45



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 2.10, 2.15 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 outstanding Loans, (y) extending any scheduled principal payment date or
date fixed for the payment of interest on the outstanding Loans or (z)
extending the Commitments).

         (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 5.10) 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 one counsel, unless in
the good faith opinion of the Agent or such counsel, it would be inappropriate
under applicable standards of legal professional conduct, due to an actual or
potential conflict of interest, to have only one counsel) incurred by the Agent
in connection with the preparation, execution and delivery of 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 their rights in connection with this Agreement (including in
respect of workouts and restructurings) or in connection with the Loans made
hereunder, including the reasonable fees and disbursements of one counsel

<PAGE>
                                                                              46



(unless in the good faith opinion of the Agent or such counsel, it would be
inappropriate under applicable standards of legal professional conduct, due to
an actual or potential conflict of interest, to have only one counsel) for the
Agent or, 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 that
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 payment, prepayment or conversion of a Eurodollar Loan
of the Borrower, or assignment of a Eurodollar Loan of the Borrower required by
any other 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
outstanding 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 relating to the Borrower, 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 that 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, each Lender,  each of
their respective 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 costs,  losses,  claims,
damages, liabilities  and related  expenses,  including  reasonable  counsel
fees of one counsel  for  all  Indemnitees  (unless  in  the  good  faith
opinion  of  such Indemnitee,  it would  be  inappropriate  under  applicable
standards  of legal professional  conduct,  due to an actual or potential
conflict of interest,  to have only one  counsel)  and  expenses,  incurred  by
or asserted  against  any Indemnitee  arising out of the Borrower's  acts or
omissions in connection  with (i)  the  preparation,   execution,  delivery,
enforcement,   performance  and administration  of this Agreement,  (ii) the
use of the proceeds of the Loans 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 part of any Indemnitee.

<PAGE>
                                                                              47


Notwithstanding the foregoing, such indemnity shall not, as to any  Indemnitee,
be  available  to the extent that such  losses,  claims, damages,  liabilities
or  related  expenses  (i)  are  determined  by a  final, non-appealable
judgment of a court of competent  jurisdiction  to have resulted from the gross
negligence  or willful  misconduct of such  Indemnitee,  or (ii) result from
any litigation brought by such Indemnitee against the Borrower or by the
Borrower against such Indemnitee, in which a final,  non-appealable 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 outstanding, 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 that such Lender or such 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 of and all 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.

         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

<PAGE>
                                                                              48


and remedies of the Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that 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 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 payable to any Lender without the prior written consent of such Lender, or
(iii) amend or modify the provisions of Section 2.12, 2.13 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 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 Agreements 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 Agreements. 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
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.
<PAGE>
                                                                              49



         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 outstanding 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 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

<PAGE>
                                                                              50


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 that 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 (as the case may be),
(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
outstanding 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, the
amounts, maturities and interest rates of its outstanding Loans, and any Fees to
which it is entitled, to any purchaser or potential purchaser of such Lender's
interest in any Loans outstanding. Notwithstanding the foregoing, each party
hereto (and each officer, director, employee, representative, agent and advisor
of each party hereto) may disclose to any and all persons, without limitation of
any kind, the "tax treatment" and "tax structure" (in each case within the
meaning of Treasury Regulation Section 1.6011-4) of the transactions
contemplated by the Loan Documents and all materials of any kind (including
opinions or other tax analyses) that are provided to such person relating to
such "tax treatment" and "tax structure". The foregoing is intended to comply
with the presumption set forth in Treasury Regulation Section
1.6011-4(b)(3)(iii) and should be interpreted in a manner consistent with such
regulation.
