               FIVE-YEAR THIRD AMENDED AND RESTATED COMPETITIVE
               ADVANCE AND REVOLVING CREDIT FACILITY AGREEMENT (the
               "Agreement"), dated as of July __, 2002, among TXU US
               HOLDINGS COMPANY, a Texas corporation ("Holdings", and
               in its capacity as borrower hereunder, the "Borrower"),
               the lenders listed in Schedule 2.01 (together with
               their successors and assigns, the "Lenders"), JPMORGAN
               CHASE BANK ("JPMorgan Chase"), as competitive advance
               facility agent (in such capacity, the "CAF Agent"), as
               administrative agent for the Lenders (in such capacity,
               the "Administrative Agent", and, together with the CAF
               Agent, the "Agents") and as fronting bank for the
               letters of credit issued hereunder.

                              PRELIMINARY STATEMENT

          Pursuant to the terms of that certain Five-Year Second Amended and
Restated Competitive Advance and Revolving Credit Facility Agreement, dated as
of February 25, 2000 and amended as of February 23, 2001, February 22, 2002 and
April 24, 2002 (the "Original Agreement"), among TXU Corp., a Texas corporation
("TXU"), the Borrower (formerly TXU Electric Company) (together with TXU, the
"Original Borrowers"), the lenders party thereto (the "Original Lenders") and
JPMorgan Chase Bank (formerly The Chase Manhattan Bank), as competitive advance
facility agent and administrative agent for the Original Lenders and fronting
bank for the letters of credit issued thereunder, the Original Lenders agreed to
extend credit in the form of Standby Borrowings to the Original Borrowers in an
aggregate principal amount at any time outstanding not in excess of
$1,400,000,000. The Original Lenders also agreed to provide a procedure pursuant
to which the Original Borrowers may invite the Original Lenders to bid on an
uncommitted basis on short-term borrowings by the Original Borrowers, and to
provide a facility for the issuance of letters of credit in an aggregate amount
not in excess of $500,000,000. The parties hereto wish to designate Holdings as
the sole borrower hereunder, to remove TXU as a borrower and to make certain
other amendments to the Original Agreement.

          Accordingly, in order to reflect the foregoing as well as certain
other modifications to the Original Agreement, the parties hereto now wish to
amend and restate the Original Agreement as herein set forth.

                                    ARTICLE I
                            DEFINITIONS; CONSTRUCTION

          SECTION 1.01.  Defined Terms.

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

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

<PAGE>

                                                                               2

               "ABR Loan" shall mean any Standby 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 2.10 or 2.14(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 TXU (within the meaning of
          Section 13(d) or 14(d) of the Exchange Act, and the applicable rules
          and regulations thereunder).

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

               "Administrative Fees" shall have the meaning assigned to such
          term in Section 2.06(b).

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

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

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

               "Alternate Base Rate" shall mean, for any day, a rate per annum
          (rounded upwards, if necessary, to the next 1/16 of 1%) equal to the
          greater of (i) the Federal Funds Effective Rate in effect on such day
          plus 0.50% and (ii) the Prime Rate in effect on such day. For purposes
          hereof, "Prime Rate" shall mean the rate of interest per annum
          publicly announced from time to time by JPMorgan Chase as its prime
          rate in effect at its principal office in New York City; each change

          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

          or, if such rate is not so released for any day that is a Business
          Day, the arithmetic average (rounded upwards to the next 1/100th of
          1%), as determined by JPMorgan Chase, of the quotations for the day of
          such transactions received by JPMorgan Chase from three Federal funds
          brokers of recognized standing selected by it. If for any reason
          JPMorgan Chase shall have determined (which determination shall be
          conclusive absent manifest error; provided that JPMorgan Chase 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 JPMorgan Chase 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 Rate, respectively.

               "Applicable Margin" shall mean the percentage per annum set forth
          in the column identified as Level 1, Level 2, Level 3 or Level 4
          below, based upon the Level corresponding to the higher Debt Rating of
          the Borrower at the time of determination, provided, that the
          Applicable Margins set forth below with respect to each Level shall be
          increased by .125% with respect to Eurodollar Loans outstanding at any
          time during a Utilization Period, provided further, that the
          Applicable Margin with respect to ABR Loans outstanding at any time
          during a Utilization Period shall be equal to, for each Level, the
          then-effective Applicable Margin for Eurodollar Loans less 1.00% (but
          not negative). Any change in the Applicable Margin shall be effective
          on the date on which the applicable rating agency announces any change
          in the Debt Rating.

          SECTION 2.01.  COMMITMENTS.

<PAGE>

                                                                              18

outstanding not to exceed such Lender's Commitment, and the Fronting Bank agrees
to issue Letters of Credit for the account of the Borrower at any time and from
time to time until the fifth Business Day preceding the Maturity Date in
aggregate stated amount at any time outstanding not to exceed the LC Commitment
Amount, subject, however, to the conditions that (i) at no time shall the sum of
(x) the outstanding aggregate principal amount of all Standby Loans plus (y) the
outstanding aggregate principal amount of all Competitive Loans plus (z) LC
Outstandings exceed the Total Commitment, (ii) at no time shall the sum of (x)
the outstanding aggregate principal amount of all Extensions of Credit plus (y)
the outstanding aggregate amount of all "Extensions of Credit" and "Borrowings"
under and as defined in the 364-Day Credit Agreement and the Bridge Facility,
respectively plus (z) the outstanding borrowings and other extensions of credit
under other credit agreements or loan agreements that the Borrower is a party
to, for the account of, or owing by, the Borrower exceed $2,000,000,000 or such
different amount reflected in the orders, resolutions and approvals referenced
in (i)(A) of the definition of "Borrower Approval Date", (iii) at no time shall
(x) the outstanding aggregate principal amount of all Standby Loans made by any
Lender plus (y) the amount by which the Competitive Loans made to the Borrower
and outstanding at such time shall be deemed to have used the Commitment of such
Lender pursuant to Section 2.15 plus (z) such Lender's Percentage of the LC
Outstandings exceed the amount of such Lender's Commitment and (iv) at all
times, the outstanding aggregate principal amount of all Standby Loans made by
each Lender to the Borrower shall equal the product of (A) the percentage that
such Lender's Commitment represents of the Total Commitment times (B) the
outstanding aggregate principal amount of all Standby Loans made to the
Borrower.

          Within the foregoing limits, the Borrower may borrow, pay or prepay
and, subject to the limitations set forth in Section 2.12(a), reborrow Standby
Loans hereunder, on and after the Restatement Date and prior to the Maturity
Date, subject to the terms, conditions and limitations set forth herein.

          SECTION 2.02.  LOANS.

          (a)  Each Standby 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
Standby 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). Each Competitive Loan shall be made in accordance
with the procedures set forth in Section 2.03. The Standby Loans or Competitive
Loans comprising any Borrowing shall be (i) in the case of Competitive Loans, in
an aggregate principal amount that is an integral multiple of $1,000,000 and not
less than $5,000,000 and (ii) in the case of Standby Loans, 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 Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Standby Borrowing
shall be comprised entirely of Eurodollar Standby Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or 2.04, as applicable. Each
Lender may at its option make any Eurodollar Loan by causing any

<PAGE>

                                                                              19

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 Administrative Agent in New York, New York,
not later than noon, New York City time, and the Administrative 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 Administrative Agent or, if a Borrowing shall not occur on such
date because any condition precedent herein specified shall not have been met,
return the amounts so received to the respective Lenders. Competitive Loans
shall be made by the Lender or Lenders whose Competitive Bids therefor are
accepted pursuant to Section 2.03 in the amounts so accepted. Standby Loans
shall be made by the Lenders pro rata in accordance with Section 2.15. Unless
the Administrative Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender's portion of such Borrowing, the Administrative
Agent may assume that such Lender has made such portion available to the
Administrative Agent on the date of such Borrowing in accordance with this
paragraph (c) and the Administrative 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 Administrative 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 Administrative 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 Administrative 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 Administrative 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 Standby
Borrowing with a Standby Borrowing of the same or a different Type, subject to
the conditions and limitations set forth in this Agreement. Any Standby
Borrowing or part thereof so refinanced shall be deemed to be repaid or prepaid
in accordance with Section 2.07 or 2.12, as applicable, with the proceeds of a
new Standby Borrowing, and the proceeds of the new Standby Borrowing, to the
extent they do not exceed the principal amount of the Standby Borrowing being
refinanced, shall not be paid by the Lenders to the Administrative Agent or by
the Administrative Agent to the Borrower pursuant to paragraph (c) above.

          SECTION 2.03.  COMPETITIVE BID PROCEDURE.

          (a)  In order to request Competitive Bids, the Borrower shall hand
deliver or telecopy to the CAF Agent a duly completed Competitive Bid Request in
the form of Exhibit A-1 hereto, to be received by the CAF Agent (i) in the case
of a Eurodollar Competitive Borrowing, not later than 11:00 a.m., New York City
time, four Business Days before a proposed Competitive Borrowing and (ii) in the
case of a Fixed Rate Borrowing, not later than 11:00 a.m., New York City time,
one Business Day before a proposed Competitive

<PAGE>

                                                                              20

Borrowing. No ABR Loan shall be requested in, or made pursuant to, a Competitive
Bid Request. A Competitive Bid Request that does not conform substantially to
the format of Exhibit A-1 may be rejected in the CAF Agent's sole discretion,
and the CAF Agent shall promptly notify the Borrower of such rejection by
telecopy. Each Competitive Bid Request shall refer to this Agreement and specify
(w) whether the Borrowing then being requested is to be a Eurodollar Borrowing
or a Fixed Rate Borrowing, (x) the date of such Borrowing (which shall be a
Business Day) and the aggregate principal amount thereof, which shall be in a
minimum principal amount of $5,000,000 and in an integral multiple of
$1,000,000, and (y) the Interest Period with respect thereto (which may not end
after the Maturity Date). Promptly after its receipt of a Competitive Bid
Request that is not rejected as aforesaid, the CAF Agent shall telecopy to each
Lender a Notice of Competitive Bid Request in the form of Exhibit A-2 inviting
the Lenders to bid, on the terms and conditions of this Agreement, to make
Competitive Loans.

          (b)  Each Lender invited to bid may, in its sole discretion, make one
or more Competitive Bids to the Borrower responsive to the Borrower's
Competitive Bid Request. Each Competitive Bid by a Lender must be received by
the CAF Agent by telecopy, in the form of Exhibit A-3 hereto, (i) in the case of
a Eurodollar Competitive Borrowing, not later than 9:30 a.m., New York City
time, three Business Days before a proposed Competitive Borrowing and (ii) in
the case of a Fixed Rate Borrowing, not later than 9:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing. Multiple bids will be
accepted by the CAF Agent. Competitive Bids that do not conform substantially to
the format of Exhibit A-3 may be rejected by the CAF Agent, and the CAF Agent
shall notify the Lender making such nonconforming bid of such rejection as soon
as practicable. Each Competitive Bid shall refer to this Agreement and specify
(x) the principal amount (which shall be in a minimum principal amount of
$5,000,000 and in an integral multiple of $1,000,000 and which may equal the
entire principal amount of the Competitive Borrowing requested by the Borrower)
of the Competitive Loan or Loans that the Lender is willing to make to the
Borrower, (y) the Competitive Bid Rate or Rates at which the Lender is prepared
to make the Competitive Loan or Loans and (z) the Interest Period and the last
day thereof. If any Lender invited to bid shall elect not to make a Competitive
Bid, such Lender shall so notify the CAF Agent by telecopy (I) in the case of
Eurodollar Competitive Loans, not later than 9:30 a.m., New York City time,
three Business Days before a proposed Competitive Borrowing, and (II) in the
case of Fixed Rate Loans, not later than 9:30 a.m., New York City time, on the
day of a proposed Competitive Borrowing; provided, however, that failure by any
Lender to give such notice shall not cause such Lender to be obligated to make
any Competitive Loan as part of such Competitive Borrowing. A Competitive Bid
submitted by a Lender pursuant to this paragraph (b) shall be irrevocable.

          (c)  The CAF Agent shall notify the Borrower by telecopy of all the
Competitive Bids made, the Competitive Bid Rate and the principal amount of each
Competitive Loan in respect of which such Competitive Bid was made and the
identity of the Lender that made each such bid by (i) in the case of a
Eurodollar Competitive Borrowing, not later than 10:00 a.m., New York City time,
three Business Days before a proposed Competitive Borrowing and (ii) in the case
of a Fixed Rate Borrowing, not later than 10:00 a.m., New York City time, on the
day of a proposed Competitive Borrowing. The CAF Agent shall send a copy of all
Competitive Bids to the

<PAGE>

                                                                              21

Borrower for its records as soon as practicable after the completion of the
bidding process set forth in this Section 2.03.

          (d)  The Borrower may in its sole and absolute discretion, subject
only to the provisions of this paragraph (d), accept or reject any or all
Competitive Bids referred to in paragraph (c) above. The Borrower shall notify
the CAF Agent by telephone, confirmed by telecopy in the form of a Competitive
Bid Accept/Reject Letter, whether and to what extent it has decided to accept or
reject any or all of the bids referred to in paragraph (c) above by (i) in the
case of a Eurodollar Competitive Borrowing, not later than 10:30 a.m., New York
City time, three Business Days before a proposed Competitive Borrowing and (ii)
in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing; provided, however, that
(i) the failure by the Borrower to give such notice shall be deemed to be a
rejection of all the bids referred to in paragraph (c) above, (ii) the Borrower
shall not accept a bid made at a particular Competitive Bid Rate if it has
decided to reject a bid made at a lower Competitive Bid Rate, (iii) the
aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed the principal amount specified in the Competitive Bid Request, (iv) if
the Borrower shall accept a bid or bids made at a particular Competitive Bid
Rate but the amount of such bid or bids shall cause the total amount of bids to
be accepted by the Borrower to exceed the amount specified in the Competitive
Bid Request, then the Borrower shall accept a portion of such bid or bids in an
amount equal to the amount specified in the Competitive Bid Request less the
amount of all other Competitive Bids accepted with respect to such Competitive
Bid Request, which acceptance, in the case of multiple bids at such Competitive
Bid Rate, shall be made pro rata in accordance with the amount of each such bid
at such Competitive Bid Rate, and (v) except pursuant to clause (iv) above, no
bid shall be accepted for a Competitive Loan unless such Competitive Loan is in
a minimum principal amount of $5,000,000 and an integral multiple of $1,000,000;
provided further, however, that if a Competitive Loan must be in an amount less
than $5,000,000 because of the provisions of clause (iv) above, such Competitive
Loan may be for a minimum of $1,000,000 or any integral multiple thereof, and in
calculating the pro rata allocation of acceptances of portions of multiple bids
at a particular Competitive Bid Rate pursuant to clause (iv) the amounts shall
be rounded to integral multiples of $1,000,000 in a manner which shall be in the
discretion of the Borrower. A notice given by the Borrower pursuant to this
paragraph (d) shall be irrevocable.

          (e)  The CAF Agent shall promptly notify each bidding Lender (and the
Administrative Agent), by telecopy, whether or not its Competitive Bid has been
accepted (and if so, in what amount and at what Competitive Bid Rate) and each
successful bidder will thereupon become bound, subject to the other applicable
conditions hereof, to make the Competitive Loan in respect of which its bid has
been accepted.

          (f)  No Competitive Borrowing shall be requested or made hereunder if
after giving effect thereto any of the conditions set forth in clauses (i), (ii)
and (iii) of Section 2.01 would not be met.

          (g)  If either the Administrative Agent or CAF Agent shall elect to
submit a Competitive Bid in its capacity as a Lender, such party shall submit
such bid directly to the Borrower one quarter of an hour earlier than the latest
time at which the other Lenders are required to submit their bids to the CAF
Agent pursuant to paragraph (b) above.

                                                                              22

          (h)  The Borrower and the CAF Agent shall deliver to the
Administrative Agent by telecopy copies of all notices delivered by it pursuant
to this Section 2.03 at the same times such notices are delivered hereunder. All
notices required by this Section 2.03 shall be given in accordance with Section
8.01.

          (i)  A Competitive Bid Request shall not be made within five Business
Days after the date of any previous Competitive Bid that was accepted by the
Borrower pursuant to paragraph (d) above.

          SECTION 2.04.  STANDBY BORROWING PROCEDURE.

          In order to request a Standby Borrowing, the Borrower shall hand
deliver or telecopy to the Administrative Agent a duly completed Standby
Borrowing Request in the form of Exhibit A-5 (a) in the case of a Eurodollar
Standby Borrowing, not later than 11:00 a.m., New York City time, three Business
Days before such Borrowing, and (b) in the case of an ABR Borrowing, not later
than 11:00 a.m., New York City time, one Business Day before such Borrowing. No
Fixed Rate Loan shall be requested or made pursuant to a Standby Borrowing
Request. Such notice shall be irrevocable and shall in each case specify (i)
whether the Borrowing then being requested is to be a Eurodollar Standby
Borrowing or an ABR Borrowing; (ii) the date of such Standby Borrowing (which
shall be a Business Day) and the amount thereof; and (iii) if such Borrowing is
to be a Eurodollar Standby Borrowing, the Interest Period with respect thereto,
which shall not end after the Maturity Date. If no election as to the Type of
Standby Borrowing is specified in any such notice, then the requested Standby
Borrowing shall be an ABR Borrowing. If no Interest Period with respect to any
Eurodollar Standby 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 2.04
of its election to refinance a Standby 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
Standby Borrowing shall be requested if the Interest Period with respect thereto
would end after the Maturity Date. The Administrative Agent shall promptly
advise the Lenders of any notice given pursuant to this Section 2.04 and of each
Lender's portion of the requested Borrowing.

          SECTION 2.05.  LETTERS OF CREDIT

          (a)  Subject to the terms and conditions hereof, each Letter of Credit
shall be issued (or the stated maturity thereof extended or terms thereof
modified or amended) on not less than three Business Days' prior notice thereof
by the delivery by the Borrower of a Request for Issuance to the Administrative
Agent (which shall promptly distribute copies thereof to the Lenders) and the
Fronting Bank. Each Request for Issuance shall specify (i) the date (which shall
be a Business Day) of issuance of such Letter of Credit (or the date of
effectiveness of such extension, modification or amendment) and the stated
expiry date thereof (which shall be no later than the earlier of (A) the first
anniversary of its date of issuance and (B) the fifth Business Day preceding the
Maturity Date, provided, that any Letter of Credit with a one-year term may
provide for the renewal thereof for additional one-year periods (which shall in
no event extend

<PAGE>

                                                                              23

beyond the date referred to in clause (B) above)), (ii) the proposed stated
amount (denominated in dollars) of such Letter of Credit (which shall not be
less than $1,000,000, unless otherwise agreed to by the Fronting Bank), (iii)
the name and address of the beneficiary of such Letter of Credit and (iv) a
statement of drawing conditions applicable to such Letter of Credit, and if such
Request for Issuance relates to an amendment or modification of a Letter of
Credit, it shall be accompanied by the consent of the beneficiary of the Letter
of Credit thereto. Each Request for Issuance shall be irrevocable unless
modified or rescinded by the Borrower that delivered such request not less than
two days prior to the proposed date of issuance (or effectiveness) specified
therein. Not later than 12:00 noon (New York City time) on the proposed date of
issuance (or effectiveness) specified in such Request for Issuance, and upon
fulfillment of the applicable conditions precedent and the other requirements
set forth herein, the Fronting Bank shall issue (or extend, amend or modify)
such Letter of Credit and provide notice and a copy thereof to the
Administrative Agent, which shall promptly furnish copies thereof to the
Lenders. Each Lender shall, upon the issuance of any Letter of Credit, acquire a
participation interest in such Letter of Credit, automatically and without any
action on its part or the part of the Fronting Bank, whereby such Lender shall
become obligated to perform such obligations in respect of such Letter of Credit
as are expressly set forth herein. The Fronting Bank shall not at any time be
obligated to issue any Letter of Credit if such issuance would conflict with any
applicable requirement of law.

          (b)  No Letter of Credit shall be requested or issued hereunder if,
after the issuance thereof, (i) the Outstanding Credits would exceed the Total
Commitment, (ii) the aggregate undrawn stated amounts of all Letters of Credit
outstanding would exceed the LC Commitment Amount or (ii) the sum of (x) the
outstanding aggregate principal amount of all Extensions of Credit plus (y) the
outstanding aggregate amount of all "Extensions of Credit" and "Borrowings"
under and as defined in the 364-Day Credit Agreement and the Bridge Facility,
respectively plus (z) the outstanding borrowings and other extensions of credit
under other credit agreements or loan agreements that the Borrower is a party
to, for the account of, or owing by, the Borrower exceed $2,000,000,000 or such
different amount reflected in the orders, resolutions and approvals referenced
in (i)(A) of the definition of "Borrower Approval Date". Furthermore, no Letter
of Credit shall be requested by, or issued to, the Borrower hereunder prior to
the Borrower Approval Date if, after the issuance thereof, the sum of (A) the
outstanding aggregate principal amount of all Loans made to the Borrower plus
(B) the aggregate amount of LC Outstandings for the account of, or owing by, the
Borrower plus (C) the outstanding aggregate principal amount of all "Loans"
under and as defined in the 364-Day Credit Agreement made to the Borrower plus
(D) the aggregate amount of "LC Outstandings" for the account of, or owing by,
the Borrower under and as defined in the 364-Day Credit Agreement would exceed
$2,000,000,000.

          (c)  The Borrower hereby agrees to pay to the Administrative Agent for
the account of the Fronting Bank and, if they shall have purchased
participations in the reimbursement obligations of the Borrower pursuant to
subsection (d) below, the Lenders, on demand made by the Fronting Bank to the
Borrower, on and after each date on which the Fronting Bank shall pay any amount
under any Letter of Credit issued by the Fronting Bank for the account of the
Borrower, a sum equal to the amount so paid plus interest on such amount from
the date so paid by the Fronting Bank until repayment to the Fronting Bank in
full at a fluctuating interest rate per annum equal to the Alternate Base Rate
plus the Applicable Margin for ABR Loans plus, if any amount paid by the
Fronting Bank under a Letter of Credit is not reimbursed by the Borrower within
three Business Days, 2%.

                                                                              24

          (d)  If the Fronting Bank shall not have been reimbursed in full by
the Borrower for any payment made by the Fronting Bank under a Letter of Credit
issued by the Fronting Bank for the account of the Borrower on the date of such
payment, the Fronting Bank shall give the Administrative Agent and each Lender
prompt notice thereof (an "LC Payment Notice") no later than 12:00 noon (New
York City time) on the Business Day immediately succeeding the date of such
payment by the Fronting Bank. Notwithstanding any provision of this Agreement to
the contrary, each Lender severally agrees to purchase a participation in the
reimbursement obligation of the Borrower to the Fronting Bank by paying to the
Administrative Agent for the account of the Fronting Bank an amount equal to
such Lender's Percentage of such unreimbursed amount paid by the Fronting Bank,
plus interest on such amount at a rate per annum equal to the Federal Funds
Effective Rate from the date of the payment by the Fronting Bank to the date of
payment to the Fronting Bank by such Lender. Each such payment by a Lender shall
be made not later than 3:00 p.m. (New York City time) on the later to occur of
(i) the Business Day immediately following the date of such payment by the
Fronting Bank and (ii) the Business Day on which the Lender shall have received
an LC Payment Notice from the Fronting Bank. Each Lender's obligation to make
each such payment to the Administrative Agent for the account of the Fronting
Bank shall be several and shall not be affected by the occurrence or continuance
of a Default or Event of Default or the failure of any other Lender to make any
payment under this Section 2.05(d). Each Lender further agrees that each such
payment shall be made without any offset, abatement, withholding or reduction
whatsoever.

          (e)  The failure of any Lender to make any payment to the
Administrative Agent for the account of the Fronting Bank in accordance with
subsection (d) above, shall not relieve any other Lender of its obligation to
make payment, but no Lender shall be responsible for the failure of any other
Lender. If any Lender (a "non-performing Lender") shall fail to make any payment
to the Administrative Agent for the account of the Fronting Bank in accordance
with subsection (d) above within five Business Days after the LC Payment Notice
relating thereto, then, for so long as such failure shall continue, the Fronting
Bank shall be deemed, for purposes of Section 2.16 and Article VI hereof, to be
a Lender hereunder owed a Loan in an amount equal to the outstanding principal
amount due and payable by such non-performing Lender to the Administrative Agent
for the account of the Fronting Bank pursuant to subsection (d) above. Any
non-performing Lender and the Borrower for the account of which the relevant
Letter of Credit was issued (without waiving any claim against such Lender for
such Lender's failure to purchase a participation in the reimbursement
obligations of the Borrower under subsection (d) above) severally agree to pay
to the Administrative Agent for the account of the Fronting Bank forthwith on
demand such amount, together with interest thereon for each day from the date
the Lender would have purchased its participation had it complied with the
requirements of subsection (d) above until the date such amount is paid to the
Administrative Agent at (i) in the case of the Borrower, the interest rate
applicable at the time to ABR Loans (or the interest rate that would be
applicable if ABR Loans were outstanding) and (ii) in the case of such Lender,
the Federal Funds Effective Rate.

          (f)  The payment obligations of each Lender under Section 2.05(d) and
of the Borrower under this Agreement in respect of any payment under any Letter
of Credit shall be unconditional and irrevocable, and shall be paid strictly in
accordance with the terms of this Agreement under all circumstances, including,
without limitation, the following circumstances:

                                                                              25

               (i)       any lack of validity or enforceability of this
          Agreement or any other agreement or instrument relating hereto or to
          such Letter of Credit;

               (ii)      any amendment or waiver of, or any consent to departure
          from, the terms of this Agreement or such Letter of Credit;

               (iii)     the existence of any claim, set-off, defense or other
          right that the Borrower may have at any time against any beneficiary,
          or any transferee, of such Letter of Credit (or any persons for whom
          any such beneficiary or any such transferee may be acting), the
          Fronting Bank, or any other person, whether in connection with this
          Agreement, the transactions contemplated hereby or by such Letter of
          Credit, or any unrelated transaction;

               (iv)      any statement or any other document presented under
          such Letter of Credit proving to be forged, fraudulent, invalid or
          insufficient in any respect or any statement therein being untrue or
          inaccurate in any respect;

               (v)       payment in good faith by the Fronting Bank under the
          Letter of Credit issued by the Fronting Bank against presentation of a
          draft or certificate that does not comply with the terms of such
          Letter of Credit; or

               (vi)      any other circumstance or happening whatsoever, whether
          or not similar to any of the foregoing.

          (g)  The Borrower assumes all risks of the acts and omissions of any
beneficiary or transferee of any Letter of Credit. Neither the Fronting Bank,
the Lenders nor any of their respective officers, directors, employees, agents
or Affiliates shall be liable or responsible for (i) the use that may be made of
such Letter of Credit or any acts or omissions of any beneficiary or transferee
thereof in connection therewith; (ii) the validity, sufficiency or genuineness
of documents, or of any endorsement thereon, even if such documents should prove
to be in any or all respects invalid, insufficient, fraudulent or forged; (iii)
payment by the Fronting Bank against presentation of documents that do not
comply with the terms of such Letter of Credit, including failure of any
documents to bear any reference or adequate reference to such Letter of Credit;
or (iv) any other circumstances whatsoever in making or failing to make payment
under such Letter of Credit, except that the Borrower and each Lender shall have
the right to bring suit against the Fronting Bank, and the Fronting Bank shall
be liable to the Borrower and any Lender, to the extent of any direct, as
opposed to consequential, damages suffered by the Borrower or such Lender, which
the Borrower or such Lender proves were caused by the Fronting Bank's wilful
misconduct or gross negligence, including, in the case of the Borrower, the
Fronting Bank's wilful failure to make timely payment under such Letter of
Credit following the presentation to it by the beneficiary thereof of a draft
and accompanying certificate(s) that strictly comply with the terms and
conditions of such Letter of Credit. In furtherance and not in limitation of the
foregoing, the Fronting Bank may accept sight drafts and accompanying
certificates presented under any Letter of Credit issued by the Fronting Bank
that appear on their face to be in order, without responsibility for further
investigation, regardless of any notice or information to the contrary, and
payment against such documents shall not constitute wilful misconduct or gross
negligence by the Fronting Bank. Notwithstanding the foregoing, no Lender shall
be obligated to

                                                                              26

indemnify the Borrower for damages caused by the Fronting Bank's wilful
misconduct or gross negligence.

          SECTION 2.06.  FEES.

          (a)  The Borrower agrees to pay to each Lender, through the
Administrative Agent, on each March 31, June 30, September 30 and December 31
(with the first payment being due on September 30, 2002) and on each date on
which the Commitment of such Lender shall be terminated or reduced as provided
herein, a facility fee (a "Facility Fee"), at a rate per annum equal to the
Facility Fee Percentage from time to time in effect on the amount of the sum of
the unused Commitment of such Lender plus the principal amount of outstanding
Extensions of Credit made by such Lender (without regard, in either case, to any
Competitive Loans made by any Lender), during the preceding quarter (or other
period commencing on the Restatement Date or ending on the Maturity Date or any
date on which the Commitment of such Lender shall be terminated). All Facility
Fees shall be computed on the basis of the actual number of days elapsed in a
year of 360 days. The Facility Fee due to each Lender shall commence to accrue
on the Restatement Date, 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 Administrative Agent, for its own
account, the administrative fees provided for in the Letter Agreement (the
"Administrative Fees").

          (c)  The Borrower agrees to pay the CAF Agent, for its own account,
the Auction Fees.

          (d)  The Borrower agrees to pay the Administrative Agent for the
account of the Fronting Bank a fronting fee (a "Fronting Fee") and such other
charges with respect to such Letter of Credit as are set forth in the Fee Letter
or otherwise agreed upon with the Fronting Bank, and agrees to pay to the
Administrative Agent for the account of the Lenders a fee (the "LC Fee") on the
face amount of each Letter of Credit issued by the Fronting Bank for the account
of the Borrower calculated at a rate per annum equal to the Applicable Margin
for Eurodollar Standby Loans, computed on the basis of the actual number of days
that each such Letter of Credit is outstanding, assuming a year of 360 days,
payable in arrears on each March 31, June 30, September 30 and December 31, and
on the date that such Letter of Credit expires or is drawn in full.

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

          SECTION 2.07.  REPAYMENT OF OUTSTANDING CREDITS; EVIDENCE OF
                         INDEBTEDNESS.

          (a)  The principal balance of each Outstanding Credit 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 Extension of Credit

<PAGE>

                                                                              27

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 Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Extension of Credit 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 Administrative 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 2.07 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 Administrative Agent to maintain such accounts or any error therein shall
not in any manner affect the obligations of the Borrower to repay the
Outstanding Credits in accordance with their terms.

          SECTION 2.08.  INTEREST ON LOANS.

          (a)  Subject to the provisions of Section 2.09, 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 and in the case of each Eurodollar
Competitive Loan, the LIBO Rate for the Interest Period in effect for such
Borrowing plus the Competitive Bid Margin offered by the Lender making such Loan
and accepted by the Borrower pursuant to Section 2.03.

          (b)  Subject to the provisions of Section 2.09, 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)  Subject to the provisions of Section 2.09, each Fixed Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

          (d)  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 JPMorgan
Chase, and such determination shall be conclusive absent manifest error;
provided that JPMorgan Chase shall, upon request, provide to the Borrower a
certificate setting forth in reasonable detail the basis for such determination.

                                                                              28

          SECTION 2.09.  DEFAULT INTEREST.

          If the Borrower shall default in the payment of the principal of or
interest on any Loan or any other amount becoming due hereunder (except for
reimbursement obligations in respect of Letters of Credit that have been
refunded with Loans), whether by scheduled maturity, notice of prepayment,
acceleration or otherwise, the Borrower shall on demand from time to time from
the Administrative Agent pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed as provided in Section
2.08(b)) equal to the Alternate Base Rate plus the Applicable Margin for ABR
Loans plus 1%.

          SECTION 2.10.  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
Administrative 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 Administrative 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 Administrative Agent shall have advised the
Borrower and the Lenders that the circumstances giving rise to such notice no
longer exist, (x) any request by the Borrower for a Eurodollar Competitive
Borrowing pursuant to Section 2.03 shall be of no force and effect and shall be
denied by the Administrative Agent and (y) any request by the Borrower for a
Eurodollar Standby Borrowing pursuant to Section 2.04 shall be deemed to be a
request for an ABR Borrowing. In the event the Required Lenders notify the
Administrative 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 Administrative
Agent shall notify the Borrower of such notice and until the Required Lenders
shall have advised the Administrative Agent that the circumstances giving rise
to such notice no longer exist, any request by the Borrower for a Eurodollar
Standby Borrowing shall be deemed a request for an ABR Borrowing. Each
determination by the Administrative Agent hereunder shall be made in good faith
and shall be conclusive absent manifest error; provided that the Administrative
Agent, shall, upon request, provide to the Borrower a certificate setting forth
in reasonable detail the basis for such determination.

          SECTION 2.11.  TERMINATION AND REDUCTION OF COMMITMENTS.

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

          (b)  Upon at least two Business Days' prior irrevocable written notice
to the Administrative 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 (A) the
aggregate amount of Outstanding Credits on the date of such termination or
reduction (after giving effect to any

<PAGE>

                                                                              29

prepayment made pursuant to Section 2.12) or (B) $50,000,000, unless the result
of such termination or reduction referred to in this clause (B) is to reduce the
Total Commitment to $0. The Administrative Agent shall advise the Lenders of any
notice given pursuant to this Section 2.11(b) and of each Lender's portion of
any such termination or reduction of the Total Commitment.

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

          SECTION 2.12.  PREPAYMENT.

          (a)  The Borrower shall have the right at any time and from time to
time to prepay any Standby Borrowing, in whole or in part, upon giving telecopy
notice (or telephone notice promptly confirmed by telecopy) to the
Administrative 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
that is an integral multiple of $10,000,000 and not less than $10,000,000. No
prepayment may be made in respect of any Competitive Borrowing.

          (b)  On the date of any termination or reduction of the Commitments
pursuant to Section 2.11, the Borrower shall pay or prepay so much of the
Standby Borrowings and/or deposit funds in the Cash Collateral Account in
respect of undrawn Letters of Credit outstanding on such date as shall be
necessary in order that the Outstanding Credits will not exceed the Total
Commitment, after giving effect to such termination or reduction.

          (c)  Each notice of prepayment shall specify the prepayment date and
the principal amount of each Borrowing (or portion thereof) to be prepaid, shall
be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein. All
prepayments under this Section 2.12 shall be subject to Section 8.05 but
otherwise without premium or penalty. All prepayments under this Section 2.12
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

          SECTION 2.13.  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 or
the Fronting Bank hereunder (except for changes in respect of taxes on the
overall net income of such Lender or the Fronting Bank (as the case may be) or
its lending office imposed by the jurisdiction in which such Lender's or the
Fronting Bank's (as the case may be) principal executive office or lending
office is located), or shall result in the imposition, modification or

<PAGE>

                                                                              30

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 the Fronting Bank, or shall result in the imposition on any Lender, the
Fronting Bank or the London interbank market of any other condition affecting
this Agreement, such Lender's Commitment or any Extension of Credit (other than
an ABR Loan) made by such Lender or the Fronting Bank, and the result of any of
the foregoing shall be to increase the cost to such Lender or the Fronting Bank
(as the case may be) of making or maintaining any Extension of Credit (other
than an ABR Loan) or to reduce the amount of any sum received or receivable by
such Lender or the Fronting Bank (as the case may be) hereunder (whether of
principal, interest or otherwise) by an amount deemed by such Lender or the
Fronting Bank (as the case may be) to be material, then the Borrower shall, upon
receipt of the notice and certificate provided for in Section 2.13(c), promptly
pay to such Lender or the Fronting Bank (as the case may be) such additional
amount or amounts as will compensate such Lender or the Fronting Bank (as the
case may be) for such additional costs incurred or reduction suffered.
Notwithstanding the foregoing, no Lender shall be entitled to request
compensation under this paragraph with respect to any Competitive Loan if the
change giving rise to such request was applicable to such Lender at the time of
submission of the Competitive Bid pursuant to which such Competitive Loan was
made.

          (b)  If any Lender or the Fronting Bank shall have determined that the
adoption of any law, rule, regulation or guideline arising out of the July 1988
report of the Basle Committee on Banking Regulations and Supervisory Practices
entitled "International Convergence of Capital Measurement and Capital
Standards," or the adoption after the date hereof of any other law, rule,
regulation or guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of the foregoing by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or the
Fronting Bank (or any lending office of such Lender or the Fronting Bank) or any
Lender's or the Fronting Bank'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 or the Fronting Bank's (as the case
may be) capital or on the capital of such Lender's or the Fronting Bank's (as
the case may be) holding company, if any, as a consequence of this Agreement,
such Lender's Commitment or the Extensions of Credit made by such Lender or the
Fronting Bank (as the case may be) pursuant hereto to a level below that which
such Lender or the Fronting Bank (as the case may be) or such Lender's or the
Fronting Bank's (as the case may be) holding company could have achieved but for
such adoption, change or compliance (taking into consideration such Lender's or
the Fronting Bank's (as the case may be) policies and the policies of such
Lender's or the Fronting Bank's (as the case may be) holding company with
respect to capital adequacy) by an amount deemed by such Lender or the Fronting
Bank (as the case may be) to be material, then from time to time such additional
amount or amounts as will compensate such Lender or the Fronting Bank (as the
case may be) for any such reduction suffered will be paid by the Borrower to
such Lender or the Fronting Bank (as the case may be). It is acknowledged that
this Agreement is being entered into by the Lenders and the Fronting Bank on the
understanding that neither the Lenders nor the Fronting Bank will be required to
maintain capital against their Commitments or agreement to issue Letters of
Credit, as the case may be, under currently applicable laws, regulations and
regulatory guidelines. In the event the Lenders or the Fronting Bank shall
otherwise determine that such understanding is incorrect, it is agreed that the
Lenders or the Fronting Bank, as the case may be, will be entitled

<PAGE>

                                                                              31

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 or the Fronting Bank setting forth
such amount or amounts as shall be necessary to compensate such Lender or the
Fronting Bank (as the case may be) 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 or the Fronting Bank (as the
case may be) the amount shown as due on any such certificate delivered by it
within 10 days after its receipt of the same. Each Lender and the Fronting Bank
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 or the Fronting Bank to give such notice shall not
constitute a waiver of such Lender's or the Fronting Bank's (as the case may be)
right to demand compensation hereunder.

          (d)  Failure on the part of any Lender or the Fronting Bank 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 or the Fronting Bank's (as the case may
be) right to demand compensation with respect to such period or any other
period; provided, however, that neither any Lender nor the Fronting Bank shall
be entitled to compensation under this Section 2.13 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 and the
Fronting Bank regardless of any possible contention of the invalidity or
inapplicability of the law, rule, regulation, guideline or other change or
condition that shall have occurred or been imposed.

          (e)  Each Lender and the Fronting Bank 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 or the Fronting Bank (as the case may be), be disadvantageous to
such Lender or the Fronting Bank (as the case may be).

          SECTION 2.14.  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 Agents, such Lender may:

               (i)       declare that Eurodollar Loans will not thereafter be
          made by such Lender hereunder, whereupon such Lender shall not submit
          a Competitive Bid in response to a request for Eurodollar Competitive
          Loans and any request for a Eurodollar Standby Borrowing shall, as to
          such Lender only, be deemed a request for an ABR Loan unless

<PAGE>

                                                                              32

          such declaration shall be subsequently withdrawn (any Lender
          delivering such a declaration hereby agreeing to withdraw such
          declaration promptly upon determining that such event of illegality no
          longer exists); and

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

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the Eurodollar Loans 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 2.14, 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 2.15.  PRO RATA TREATMENT.

          Except as provided below in this Section 2.15 with respect to
Competitive Borrowings and as required under Sections 2.14 and 2.19, each
Standby Borrowing, each payment or prepayment of principal of any Standby
Borrowing, each payment of interest on the Standby Loans, each payment of the
Facility Fees, each reduction of the Commitments and each refinancing or
conversion of any Borrowing with a Standby 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 Standby
Loans). Each payment of principal of any Competitive Borrowing shall be
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective principal amounts of their outstanding
Competitive Loans comprising such Borrowing. Each payment of interest on any
Competitive Borrowing shall be allocated pro rata among the Lenders
participating in such Borrowing in accordance with the respective amounts of
accrued and unpaid interest on their outstanding Competitive Loans comprising
such Borrowing. For purposes of determining the available Commitments of the
Lenders at any time, each outstanding Competitive Borrowing shall be deemed to
have utilized the Commitments of the Lenders (including those Lenders that shall
not have made Loans as part of such Competitive Borrowing) pro rata in
accordance with such respective Commitments, and the LC Outstandings shall be
deemed to have utilized the Commitments of the Lenders pro rata in accordance
with their respective Commitments. Each Lender agrees that in computing such
Lender's portion of any Borrowing to be made hereunder, the Administrative Agent
may, in its discretion, round each Lender's percentage of such Borrowing to the
next higher or lower whole dollar amount.

          SECTION 2.16.  SHARING OF SETOFFS.

          Each Lender agrees that if it shall, through the exercise of a right
of banker's lien, setoff or counterclaim, or pursuant to a secured claim under
Section 506 of Title 11 of the United States

<PAGE>

                                                                              33

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 Standby Loans or LC
Outstandings as a result of which the unpaid principal portion of its Standby
Loans and LC Outstandings shall be proportionately less than the unpaid
principal portion of the Standby Loans and LC Outstandings 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 Standby Loans or LC Outstandings of such other Lender, so
that the aggregate unpaid principal amount of the Standby Loans and LC
Outstandings and participations in the Standby Loans and LC Outstandings held by
each Lender shall be in the same proportion to the aggregate unpaid principal
amount of all Standby Loans and LC Outstandings then outstanding as the
principal amount of its Standby Loans and LC Outstandings prior to such exercise
of banker's lien, setoff or counterclaim or other event was to the principal
amount of all Standby Loans and LC Outstandings 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 2.16 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
Standby Loan or LC Outstandings 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 an Extension of Credit in the amount of such
participation.

          SECTION 2.17.  PAYMENTS.

          (a)  The Borrower shall make each payment (including principal of or
interest on any Extension of Credit 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 Administrative Agent at its offices at
One Chase Manhattan Plaza, 8th Floor, New York, New York 10081, Attention: Loan
and Agency Services Group, in immediately available funds. Each such payment
shall be made without off-set, deduction or counterclaim, provided, that the
foregoing shall not constitute a relinquishment or waiver of the Borrower's
rights to any independent claim that the Borrower may have against either Agent,
the Fronting Bank or any Lender.

          (b)  Whenever any payment (including principal of or interest on any
Extension of Credit 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 2.18.  TAXES.

          (a)  Any and all payments of principal and interest on any of the
Outstanding Credits, or of any Fees or indemnity or expense reimbursements by
the Borrower hereunder ("Borrower

<PAGE>

                                                                              34

Payments") shall be made, in accordance with Section 2.17, free and clear of and
without deduction for any and all current or future United States Federal, state
and local taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect to such Borrower Payments, but only to the extent
reasonably attributable to such Borrower Payments, excluding (i) income taxes
imposed on the net income of the Administrative Agent, the CAF Agent, the
Fronting Bank 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 Administrative Agent, the CAF Agent, the
Fronting Bank or any Lender (or Transferee), in each case by the jurisdiction
under the laws of which the Administrative Agent, the CAF Agent, the Fronting
Bank 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 Agents or the Fronting Bank, (i) the sum
payable shall be increased by the amount (an "additional amount") necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.18) such Lender (or Transferee) or
Agent or the Fronting Bank (as the case may be) shall receive an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with
applicable law.

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

          (c)  The Borrower shall indemnify each Lender (or Transferee thereof),
each Agent and the Fronting Bank 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, the CAF Agent, the Fronting Bank, or the Administrative 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 any Agent or the Fronting Bank, as the case may be,
makes written demand therefor.

          (d)  If a Lender (or Transferee) or any Agent or the Fronting Bank
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 2.18, 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

<PAGE>

                                                                              35

for such refund at the Borrower's expense. If a Lender (or Transferee) or any
Agent or the Fronting Bank 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 2.18, 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 2.18 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 such Agent or the Fronting Bank and without
interest (other than interest paid by the relevant United States Governmental
Authority with respect to such refund); provided, however, that the Borrower,
upon the request of such Lender (or Transferee) or such Agent or the Fronting
Bank, agrees to repay the amount paid over to the Borrower (plus penalties,
interest or other charges) to such Lender (or Transferee) or such Agent or the
Fronting Bank in the event such Lender (or Transferee) or such Agent or the
Fronting Bank 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
Administrative 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 2.18
shall survive the payment in full of the principal of and interest on all
Extensions of Credit made hereunder.

          (g)  Each of the Agents, the Fronting Bank 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 Administrative 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 2.18(g), a Non-U.S. Lender shall not be required to deliver any form
pursuant to this Section 2.18(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

<PAGE>

                                                                              36

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 an Extension of Credit;
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 the
Fronting Bank 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,
participation or transfer to such Transferee, or the Fronting Bank 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 of the Fronting Bank or any Lender (or Transferee) claiming
any indemnity payment or additional amounts payable pursuant to this Section
2.18 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 the Fronting
Bank or such Lender (or Transferee) (as the case may be), be otherwise
disadvantageous to the Fronting Bank or such Lender (or Transferee) (as the case
may be).

          (j)  Nothing contained in this Section 2.18 shall require any Lender
(or Transferee) or any Agent or the Fronting Bank to make available to the
Borrower any of its tax returns (or any other information) that it deems to be
confidential or proprietary.

          SECTION 2.19.  ASSIGNMENT OF COMMITMENTS UNDER CERTAIN CIRCUMSTANCES.

          In the event that any Lender or the Fronting Bank shall have delivered
a notice or certificate pursuant to Section 2.13 or 2.14, or the Borrower shall
be required to make additional payments to any Lender or the Fronting Bank under
Section 2.18, the Borrower shall have the right, at its own expense, upon notice
to such Lender or the Fronting Bank (as the case may be) and the Agents, to
require such Lender or the Fronting Bank (as the case may be) to transfer and
assign without recourse (in accordance with and subject to the restrictions
contained in Section 8.04) all such Lender's or the Fronting Bank's (as the case
may be) interests, rights and obligations contained hereunder to another
financial institution approved by the Agents 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 or the Fronting Bank (as the case may be) in
immediately available funds on the date of such assignment the principal of and
interest accrued to the date of payment on the Extensions of

<PAGE>

                                                                              37

Credit 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

other constitutive documents or by-laws of the Borrower or any of its
Subsidiaries to which the Borrower is subject, (y) any order of any Governmental
Authority or (z) any provision of any indenture, agreement or other instrument
to which the Borrower or any of its Subsidiaries is a party or by which it or

connection with this Agreement contains or will contain any material

they were or will be made, not misleading.

          SECTION 3.10.  TAXES.

          The Borrower and its Subsidiaries have filed or caused to be filed

Adverse Change, and no Multiemployer Plan is reasonably expected to be in
reorganization or to be terminated where such reorganization or termination has
resulted or can reasonably be expected to result, through an increase in the
contributions required to be made to such Plan or otherwise, in a Material
Adverse Change.

Borrower's Significant Subsidiaries have all material governmental licenses,
authorizations, consents and approvals required to carry on the business of the
Significant Subsidiaries substantially as now conducted.

          SECTION 3.13.  ENVIRONMENTAL MATTERS.

          Except as set forth in or contemplated by the financial statements or
other reports of the type referred to in Section 5.03 hereof, which have been
delivered to the Lenders on or prior to the date hereof, the Borrower and each
of its Subsidiaries has complied in all material respects with all Federal,
state, local and other statutes, ordinances, orders, judgments, rulings and
regulations relating to environmental pollution or to environmental or nuclear
regulation or control, except to the extent that failure to so comply could not
reasonably be expected to result in a Material Adverse Change. Except as set
forth in or contemplated by such financial statements or other reports, neither
the Borrower nor any of its Subsidiaries has received notice of any material
failure so to comply, except where such failure could not reasonably be expected
to result in a Material Adverse Change. Except as set forth in or contemplated
by such financial statements or other reports, the facilities of the Borrower or
any of its Subsidiaries, as the case may be, are not used to manage any
hazardous wastes, hazardous substances, hazardous materials, toxic substances,

Clean Water Act or any other applicable law relating to environmental pollution,

the extent that such violations could not reasonably be expected to result in a
Material Adverse Change. Except as set forth in or contemplated by such
financial statements or other reports, the Borrower is aware of no events,

shall, by notice to the Borrower, take either or both of the following actions,
at the same or different times: (i) terminate forthwith the right of the

<PAGE>

                                                                              51

accrued hereunder shall automatically become due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are
hereby expressly waived by the Borrower, anything contained herein to the
contrary notwithstanding.

          Notwithstanding anything to the contrary contained herein, no notice
given or declaration made by the Administrative Agent pursuant to this Article
VI shall affect (i) the obligation of the Fronting Bank to make any payment
under any Letter of Credit in accordance with the terms of such Letter of Credit
or (ii) the obligations of each Lender in respect of each such Letter of Credit;
provided, however, that upon the occurrence and during the continuance of any
Event of Default, the Administrative Agent shall at the request or may with the
consent of the Required Lenders, upon notice to the Borrower require the
Borrower to deposit with the Administrative Agent an amount in the cash
collateral account (the "Cash Collateral Account") described below equal to the
aggregate maximum amount available to be drawn under all Letters of Credit and
outstanding at such time. Such Cash Collateral Account shall at all times be
free and clear of all rights or claims of third parties. The Cash Collateral
Account shall be maintained with the Administrative Agent in the name of, and
under the sole dominion and control of, the Administrative Agent, and amounts
deposited in the Cash Collateral Account shall bear interest at a rate equal to
the rate generally offered by JPMorgan Chase for deposits equal to the amount
deposited by the Borrower in the Cash Collateral Account, for a term to be
determined by the Administrative Agent in its sole discretion. The Borrower
hereby grants to the Administrative Agent for the benefit of the Fronting Bank
and the Lenders a Lien on, and hereby assigns to the Administrative Agent for
the benefit of the Fronting Bank and the Lenders all of its right, title and
interest in, the Cash Collateral Account and all funds from time to time on
deposit therein to secure its reimbursement obligations in respect of Letters of
Credit issued for its account. If any drawings then outstanding or thereafter
made are not reimbursed in full immediately upon demand or, in the case of
subsequent drawings, upon being made, then, in any such event, the
Administrative Agent may apply the amounts then on deposit in the Cash
Collateral Account, in such priority as the Administrative Agent shall elect,
toward the payment in full of any or all of the Borrower's obligations hereunder
as and when such obligations shall become due and payable, regardless of whether
the amounts to be so applied were deposited by the Borrower. Upon payment in
full, after the termination of the Letters of Credit, of all such obligations,
the Administrative Agent will repay and reassign to the Borrower any cash then
on deposit in the Cash Collateral Account and the Lien of the Administrative
Agent on the Cash Collateral Account and the funds therein shall automatically
terminate.

                                   ARTICLE VII
                                   THE AGENTS

          In order to expedite the transactions contemplated by this Agreement,
JPMorgan Chase is hereby appointed to act as Administrative Agent and CAF Agent
on behalf of the Lenders and the Fronting Bank. Each of the Lenders and the
Fronting Bank hereby irrevocably authorizes the Agents to take such actions on
behalf of such Lender or holder and the Fronting Bank and to exercise such
powers as are specifically delegated to the Agents by the terms and provisions
hereof, together with such actions and powers as are reasonably incidental
thereto. The Administrative Agent is hereby expressly authorized by the Lenders,
the Fronting Bank and the CAF Agent, without hereby limiting any implied
authority, (i) to receive on behalf of the

<PAGE>

                                                                              52

Lenders, the Fronting Bank and the CAF Agent all payments of principal of and
interest on the Outstanding Credits and all other amounts due to the Lenders,
the Fronting Bank and the CAF Agent hereunder, and promptly to distribute to
each Lender, the Fronting Bank and the CAF Agent its proper share of each
payment so received, (ii) to give notice on behalf of each of the Lenders and
the Fronting Bank to the Borrower of any Event of Default of which the
Administrative Agent has actual knowledge acquired in connection with its agency
hereunder and (iii) to distribute to each Lender and the Fronting Bank copies of
all notices, financial statements and other materials delivered by the Borrower
pursuant to this Agreement as received by the Administrative Agent.

          No Agent or any of its directors, officers, employees or agents shall
be liable as such for any action taken or omitted by any of them except for its
or his or her own gross negligence or willful misconduct, or be responsible for
any statement, warranty or representation herein or the contents of any document
delivered in connection herewith, or be required to 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
Agents shall not be responsible to the Lenders or the Fronting Bank for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements. The Agents may deem and treat the
Lender or the Fronting Bank which makes any Extension of Credit as the holder of
the indebtedness resulting therefrom for all purposes hereof until it shall have
received notice from such Lender or the Fronting Bank (as the case may be),
given as provided herein, of the transfer thereof. The Agents 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 and the Fronting Bank. Each
of the Agents 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. No
Agent or any of its directors, officers, employees or agents shall have any
responsibility to the Borrower on account of the failure of or delay in
performance or breach by the other Agent or any Lender or the Fronting Bank of
any of its obligations hereunder or to the other Agent or any Lender or the
Fronting Bank on account of the failure of or delay in performance or breach by
any other Lender or the Fronting Bank, the other Agent or the Borrower of any of
its obligations hereunder or in connection herewith. Each of the Agents may
execute any and all duties hereunder by or through agents or employees and shall
be entitled to rely upon the advice of legal counsel selected by it with respect
to all matters arising hereunder and shall not be liable for any action taken or
suffered in good faith by it in accordance with the advice of such counsel.

          The Lenders and the Fronting Bank hereby acknowledge that neither of
the Agents shall be under any duty to take any discretionary action permitted to
be taken by it pursuant to the provisions of this Agreement unless it shall be
requested in writing to do so by the Required Lenders.

          Subject to the appointment and acceptance of a successor Agent as
provided below, either Agent may resign at any time by notifying the Lenders,
the Fronting Bank 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

<PAGE>

                                                                              53

Lenders and shall have accepted such appointment within 30 days after the
retiring Agent gives notice of its resignation, then the retiring Agent may, on
behalf of the Lenders and the Fronting Bank, 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 any
Agent's resignation hereunder, the provisions of this Article and Section 8.05
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as Agent.

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

          Each Lender agrees (i) to reimburse the Agents, on demand, in the
amount of its pro rata share (based on its Commitment hereunder or, if the
Commitments shall have been terminated, the amount of its Outstanding Credits)
of any expenses incurred for the benefit of the Lenders or the Fronting Bank in
its role as Agent, including counsel fees and compensation of agents and
employees paid for services rendered on behalf of the Lenders or the Fronting
Bank, which shall not have been reimbursed by the Borrower and (ii) to indemnify
and hold harmless each of the Agents and any of its directors, officers,
employees or agents, on demand, in the amount of such pro rata share, from and
against any and all liabilities, taxes, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever that may be imposed on, incurred by or asserted against it in
any way relating to or arising out of this Agreement or any action taken or
omitted by it under this Agreement to the extent the same shall not have been
reimbursed by the Borrower; provided that no Lender shall be liable to any 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 such Agent or any of its directors,
officers, employees or agents. Each Lender and the Fronting Bank agrees that any
allocation made in good faith by the Agents of expenses or other amounts
referred to in this paragraph between this Agreement and the 364-Day Credit
Agreement shall be conclusive and binding for all purposes.

          Each Lender and the Fronting Bank acknowledges that it has,
independently and without reliance upon the Agents or any other Lender or the
Fronting Bank and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender and the Fronting Bank also acknowledges that it will,
independently and without reliance upon the Agents or any other Lender or the
Fronting Bank 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.

          Neither Bank of America, N.A. nor Citibank, N.A. shall, by virtue of
its designation as "Co-Syndication Agent", nor shall The Bank of New York, by
virtue of its designation as

"Documentation Agent", have any duties, liabilities, obligations or
responsibilities under this Agreement other than as a Lender hereunder.

          SECTION 8.03.  BINDING EFFECT.

          This Agreement shall become effective on the Restatement Date, and
thereafter shall be binding upon and inure to the benefit of the parties hereto

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 the Outstanding Credits at the time owing to
it); 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, the Agents and the Fronting Bank 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 Acceptance
with respect to such assignment is delivered to the Administrative Agent) shall
not be less than $5,000,000 or, if the amount of the Commitment of the assigning
Lender is less than $5,000,000, the aggregate amount of such Lender's
Commitment, (iii) each such assignment shall be of a constant, and not a
varying, percentage of all the assigning Lender's rights and obligations under
this Agreement and (iv) the parties to each such assignment shall execute and
deliver to the Administrative Agent an Assignment and Acceptance, and a
processing and recordation fee of $3,500 (provided that, in the case of
simultaneous assignment of interests under one or more of this Agreement and the
364-Day Credit Agreement, the aggregate fee shall be $3,500). Upon acceptance
and recording pursuant to Section 8.04(e), from and after the effective date
specified in each Assignment and Acceptance, which effective date shall be at
least five Business Days after the execution thereof unless otherwise agreed by
the Administrative Agent (the Borrower to be given reasonable notice of any
shorter period), (A) the assignee thereunder shall be a party hereto and, to the
extent of the interest assigned by such Assignment and Acceptance, have the

Lender thereunder shall, to the extent of the interest assigned by such

its assignment as well as to any Fees accrued for its account hereunder and not
yet paid)). Notwithstanding the foregoing, any Lender assigning its rights and
obligations under this Agreement may retain any Competitive Loans made by it

accordance with this Agreement.

          (c)  By executing and delivering an Assignment and Acceptance, 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:
(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 Acceptance, (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 Acceptance, (v) such assignee will
independently and without reliance upon the Agents, such assigning Lender or any
other Lender or the Fronting Bank 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 each Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement as are delegated to such 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 Administrative Agent shall maintain at one of its offices in
the City of New York a copy of each Assignment and Acceptance 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 Credits owing
to, 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 Agents, the Fronting Bank 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 Acceptance
executed by an assigning Lender and an assignee, the processing and recordation
fee referred to in paragraph (b) above and, if required, the written consent of
the Borrower, the Agents and the Fronting Bank to such assignment, the
Administrative Agent shall (i) accept such Assignment and Acceptance and (ii)
record the information contained therein in the Register.

          (f)  Each Lender may without the consent of the Borrower or the Agents
sell participations to one or more banks or other entities in all or a portion
of its rights and/or obligations under this Agreement (including all or a
portion of its Commitment and the Outstanding Credits owing to it); provided,
however, that (i) such Lender's obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) each participating bank or
other entity

<PAGE>

                                                                              57

shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.13, 2.18 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 Agents, the Fronting
Bank 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 Credits, (y) extending any scheduled principal payment date or date
fixed for the payment of interest on the Outstanding Credits 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 5.09) by the Borrower without such consent shall be
void.

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

          (j)  Subject to the appointment and acceptance of a successor Fronting
Bank as provided below, the Fronting Bank 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 Fronting Bank 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
Fronting Bank gives notice of its resignation, then the retiring Fronting Bank
may appoint a successor Fronting Bank, 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 Fronting Bank hereunder by a successor bank, such successor
shall succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Fronting Bank and the retiring Fronting Bank shall be
discharged from its duties and obligations hereunder. After the Fronting Bank's
resignation hereunder, the provisions of Sections 2.13, 2.18 and 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 Fronting Bank.

          SECTION 8.05.  EXPENSES; INDEMNITY.

          (a)  The Borrower agrees to pay all reasonable out-of-pocket expenses
incurred by the Agents in connection with entering into this Agreement or in
connection with any amendments, modifications or waivers of the provisions
hereof (but only if such amendments, modifications or waivers are requested by
the Borrower) (whether or not the transactions hereby contemplated are
consummated), or incurred by the Agents, the Fronting Bank or any Lender in
connection with the enforcement of their rights in connection with this
Agreement or in connection with the Extensions of Credit made hereunder,
including the reasonable fees and disbursements of counsel for the Agents or, in
the case of enforcement following an Event of Default, the Lenders and the
Fronting Bank. In addition to the foregoing, the Borrower shall pay or reimburse
the Fronting Bank for such reasonable, normal and customary costs and expenses
as are incurred or charged by the Fronting Bank in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit.

          (b)  The Borrower agrees to indemnify each Lender and the Fronting
Bank against any loss, calculated in accordance with the next sentence, or
reasonable expense that such Lender or the Fronting Bank (as the case may be)
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 or 2.04, (ii)
any payment, prepayment or conversion, or assignment of a Eurodollar Loan or
Fixed Rate 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 Credit or any part thereof
or interest accrued thereon, as and when due and payable (at the due date
thereof, whether by scheduled maturity, acceleration, irrevocable notice of
prepayment or otherwise) or (iv) the occurrence of any Event of Default,
including, in each such case, any loss or reasonable expense sustained or
incurred or to be sustained or incurred by such Lender in liquidating or
employing deposits from third parties, or with respect to commitments made or
obligations undertaken with third parties, to effect or maintain any Loan
hereunder or any part thereof as a Eurodollar Loan or a Fixed Rate 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 or, in the case of a Fixed Rate Loan, the fixed rate of interest
applicable thereto) 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 Agents, each Lender, the
Fronting Bank, each of their Affiliates and the directors, officers, employees
and agents of the foregoing (each such person being called an "Indemnitee")
against, and to hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including reasonable counsel

                                                                              59

fees and expenses, incurred by or asserted against any Indemnitee arising out of
(i) the preparation, execution, delivery, enforcement, performance and
administration of this Agreement, (ii) the use of the proceeds of the Extensions
of Credit 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; provided that 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 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, nonappealable judgment has been rendered against
such Indemnitee; provided, further, that the Borrower agrees that it will not,
nor will it permit any Subsidiary to, without the prior written consent of each
Indemnitee, settle, compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification could be sought under the indemnification provisions of this
Section 8.05(c) (whether or not any Indemnitee is an actual or potential party
to such claim, action, suit or proceeding), unless such settlement, compromise
or consent does not include any statement as to an admission of fault,
culpability or failure to act by or on behalf of any Indemnitee and does not
involve any payment of money or other value by any Indemnitee or any injunctive
relief or factual findings or stipulations binding on any Indemnitee.

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

          (e)  A certificate of any Lender, the Fronting Bank or any Agent
setting forth any amount or amounts that such Lender, the Fronting Bank 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 and the Fronting Bank 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 or the Fronting
Bank 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 or the Fronting Bank (as the case may be), irrespective of
whether or not such Lender or the Fronting Bank (as the case may be) shall have
made any demand under this Agreement and although such obligations may be
unmatured. The rights of each Lender and the Fronting Bank under this Section
are in addition to other rights and remedies (including other rights of setoff)
which such Lender or the Fronting Bank (as the case may be) 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 either Agent or any Lender or the Fronting
Bank in exercising any power or right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Agents, the Lenders and the
Fronting Bank 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 Outstanding Credit, or waive or excuse any such payment or
any part thereof, or decrease the rate of interest on any Outstanding Credit,
without the prior written consent of each Lender affected thereby, (ii) increase
any Commitment or decrease the Facility Fee of any Lender without the prior
written consent of such Lender, or (iii) amend or modify the provisions of
Section 2.15, 2.16 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 Administrative Agent or the CAF
Agent or the Fronting Bank hereunder without the prior written consent of the
Administrative Agent or the CAF Agent or the Fronting Bank, as the case may be.
Each Lender and the Fronting Bank shall be bound by any waiver, amendment or
modification authorized by this Section and any consent by any Lender, any Agent
or the Fronting Bank pursuant to this Section shall bind any assignee of its
rights and interests hereunder.

          SECTION 8.09.  ENTIRE AGREEMENT.

          This Agreement (including the schedules and exhibits hereto) and the
Letter Agreement represent the entire contract among the parties relative to the
subject matter hereof and thereof. Any previous agreement, whether written or
oral, among the parties with respect to the subject matter hereof, including,
without limitation, the Original Agreement, is superseded by this Agreement and
the Letter Agreement. There are no unwritten oral agreements between the
parties. Nothing in this Agreement, expressed or implied, is intended to confer
upon any party other than the parties hereto any rights, remedies, obligations
or liabilities under or by reason of this Agreement.

                                                                              61

          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.

          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 that 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 or
the Fronting Bank, shall exceed the maximum lawful rate (the "Maximum Rate")
which may be contracted for, charged, taken, received or reserved by such Lender
or the Fronting Bank (as the case may be) in accordance with applicable law, the
rate of interest payable on the Outstanding Credits of such Lender or the
Fronting Bank (as the case may be), together with all Charges payable to such
Lender or the Fronting Bank (as the case may be), shall be limited to the
Maximum Rate.

          (b)  If the amount of interest, together with all Charges, payable for
the account of any Lender or the Fronting Bank 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 or the
Fronting Bank's (as the case may be) account in respect of any subsequent
interest computation period, computed pursuant to Section 2.08, would be less
than the Maximum Rate, then the amount of interest, together with all Charges,
payable for such Lender's or the Fronting Bank's (as the case may be) 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 or the Fronting Bank 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.

                                                                              62

          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 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 and the Fronting Bank shall use its best efforts to hold
in confidence all information, memoranda, or extracts furnished to such Lender
or the Fronting Bank (as the case may be) (directly or through the Agents) by
the Borrower hereunder or in connection with the negotiation hereof; provided
that such Lender and the Fronting Bank 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 or the Fronting Bank
(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 or the Fronting Bank (as the case may be)
sells or proposes to sell an assignment or a participation in its Extensions of
Credit 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 or the Fronting Bank (as the case may be)
independently of any disclosure by the Borrower hereunder or in connection with
the negotiation hereof. Notwithstanding the foregoing, any Lender and the
Fronting Bank may disclose the provisions of this Agreement and the amounts,
maturities and interest rates of its Outstanding Credits to any purchaser or
potential purchaser of such Lender's or the Fronting Bank's (as the case may be)
interest in any Outstanding Credits.

          SECTION 8.16.  TRANSITION PROVISIONS.

          By its execution and delivery of this Agreement and upon the
Restatement Date, each Lender listed in the signature pages to this Agreement
under the caption "Lenders" shall be

deemed to have entered into one or more Assignment and Acceptances with the
Original Lenders that are parties hereto on the terms set forth in this Section
8.16, Section 8.04 and Exhibit B hereto, pursuant to which each such Lender
shall be deemed to have acquired from the Original Lenders (and the Original
Lenders shall be deemed to have transferred to each such Lender) such portions
of the Original Lenders' several Commitments under (and as such term is defined
in) the Original Agreement as will result in each Lender hereunder having a
Commitment equal to the amount set forth for such Lender on Schedule 2.01 to
this Agreement. The Borrower and each of the Agents hereby consents to all such
assignments, acquisitions and transfers. No processing fees shall be payable
pursuant to Section 8.04 in connection with the foregoing.

                       [Signature pages follow]

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
