     required by law) or other ownership interest of such Subsidiary which are
     at the time owned by such Person or by one or more Wholly-Owned
     Subsidiaries of such Person, or both.

                         AMOUNTS AND TERMS OF THE LOANS

     SECTION 2.1. The Commitments. (a) Each Bank severally agrees, on the terms
and subject to the conditions hereinafter set forth, to make revolving credit
Loans ("Revolving Loans") to the Borrower from time to time on any Business Day
during the period from the Closing Date until the Revolving Commitment
Termination Date in an aggregate principal amount outstanding, which does not
exceed at any time such Bank's Commitment; provided that (x) no more than six
Borrowings shall be made hereunder and (y) no Revolving Loan shall be made as a
LIBOR Rate Loan with an Interest Period ending after the Revolving Commitment
Termination Date; and provided, further, that in no event shall (x) the Total
Outstanding Loans at any time exceed the Total Commitments at such time and (y)
the aggregate principal amount of any requested Borrowing on any date exceed the
aggregate principal amount outstanding under the Existing Credit Agreement.

     (b) Each Borrowing by the Borrower shall be in an aggregate principal
amount not less than $10,000,000 (in the case of LIBOR Rate Loans) or $5,000,000
(in the case of ABR Loans), or an integral multiple of $1,000,000 in excess
thereof and shall consist of Revolving Loans of


                                       22
<PAGE>
the same Type made on the same day by the Banks ratably according to their
respective Revolving Percentages. Within the limits of the applicable
Commitments, the Borrower may borrow, prepay pursuant to Section 4.6 and
reborrow under this Section 2.1. Subject to Section 2.4, the principal amount
outstanding on the Revolving Loans shall be due and payable, and the Commitment
of each Bank shall terminate, on the Revolving Commitment Termination Date,
together with accrued and unpaid interest thereon.

     SECTION 2.2. Procedure for Revolving Loan Borrowing. (a) The Borrower may
borrow under the Commitments on any Business Day during the period from and
including the Closing Date to and excluding the Revolving Commitment Termination
Date, provided that the Borrower shall give the Administrative Agent irrevocable
oral notice or written notice pursuant to a notice of borrowing, in
substantially the form of Exhibit A hereto ("Notice of Borrowing") which shall
be signed by the Borrower and shall specify therein the requested (i) date of
such Borrowing, (ii) Type of Revolving Loans comprising such Borrowing, (iii)
aggregate amount of such Borrowing and (iv) the Interest Period for each such
Revolving Loan, in the case of any LIBOR Rate Loan,:

          (i) not later than 11:00 A.M. (New York City time) on the third
     Business Day prior to the date of the proposed Borrowing in the case of a
     LIBOR Rate Loan;

          (ii) not later than 11:00 A.M. (New York City time) on the Business
     Day immediately preceding the date of the proposed Borrowing in the case of
     an Early Funding ABR Loan; and

          (iii) not later than 11:00 A.M. (New York City time) on the same
     Business Day of the proposed Borrowing in the case of any other ABR Loan.

With respect to any oral notice of borrowing given by the Borrower, the Borrower
shall promptly thereafter confirm such notice in writing pursuant to a Notice of
Borrowing. Upon receipt of any such notice, the Administrative Agent shall
promptly notify each Bank thereof. Each Bank shall, before 1:00 P.M. (New York
City time) on the date of such Borrowing, make available to the Administrative
Agent at the Funding Office, in immediately available funds, such Bank's
applicable Revolving Percentage of such Borrowing; provided, however, that, in
the event of a requested ABR Loan with respect to which the Borrower has
delivered its Notice of Borrowing on the Business Day immediately preceding the
requested Borrowing Date (an "Early Funding ABR Loan"), each Bank shall make its
applicable Revolving Percentage of such Borrowing available before 10:00 A.M.
(New York City time) on the requested Borrowing Date. The Administrative Agent
shall, no later than 2:00 P.M. (New York City time) on such date (or no later
than 11:00 A.M. (New York City time), in the case of an Early Funding ABR Loan),
make available to the Borrower the proceeds of the Revolving Loans received by
the Administrative Agent hereunder by crediting such account of the Borrower
which the Administrative Agent and the Borrower shall from time to time
designate. Each Notice of Borrowing shall be irrevocable and binding on the
Borrower.

     (b) Unless the Administrative Agent shall have received notice from a Bank
at least two hours prior to the applicable time described in clause (a) above by
which such Bank is required to deliver its funds to the Administrative Agent
with respect to any Borrowing that such Bank


                                       23
<PAGE>
will not make available to the Administrative Agent such Bank's applicable
Revolving Percentage of such Borrowing, the Administrative Agent may assume that
such Bank has made such portion available to the Administrative Agent on the
date of such Borrowing in accordance with Section 2.2(a) and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower on
such date a corresponding amount. If such amount is made available to the
Administrative Agent on a date after such date of Borrowing, such Bank shall pay
to the Administrative Agent on demand an amount equal to the product of (i) the
daily average Federal Funds Effective Rate during such period, times (ii) the
amount of such Bank's applicable Revolving Percentage of such Borrowing, times
(iii) a fraction, the numerator of which is the number of days that elapse from
and including such date of Borrowing to the date on which such Bank's applicable
Revolving Percentage of such Borrowing shall have become immediately available
to the Administrative Agent and the denominator of which is 360. A certificate
of the Administrative Agent submitted to any Bank with respect to any amounts
owing under this Section 2.2(b) shall be conclusive in the absence of manifest
error. If such Bank shall repay to the Administrative Agent such corresponding
amount, such amount so repaid shall constitute such Bank's Revolving Loan as
part of such Borrowing for purposes of this Agreement. If such Bank's applicable
Revolving Percentage of such Borrowing is not in fact made available to the
Administrative Agent by such Bank within one (1) Business Day of such date of
Borrowing, the Administrative Agent shall be entitled to recover such amount
with interest thereon at the rate per annum, equal to (i) the ABR (in the case
of ABR Loans) or (ii) the Federal Funds Effective Rate (in the case of LIBOR
Rate Loans), on demand, from the Borrower.

     (c) The failure of any Bank to make the Revolving Loan to be made by it as
part of any Borrowing shall not relieve any other Bank of its obligation, if
any, hereunder to make its Revolving Loan on the date of such Borrowing, but no
Bank shall be responsible for the failure of any other Bank to make the
Revolving Loan to be made by such other Bank on the date of any Borrowing.

     SECTION 2.3. Minimum Tranches. All Borrowings, prepayments, conversions and
continuations of Loans hereunder and all selections of Interest Periods
hereunder shall be in such amounts and be made pursuant to such elections so
that, after giving effect thereto, the aggregate principal amount of the Loans
comprising each Tranche of LIBOR Rate Loans shall be equal to $10,000,000 or an
integral multiple of $1,000,000 in excess thereof.

     SECTION 2.4. Conversion of Revolving Loans to Term Loans. (a) The aggregate
principal amount of the Revolving Loans outstanding on the Revolving Commitment
Termination Date shall be converted into, and the Banks shall be deemed to have
made, term loans to the Borrower on the Revolving Commitment Termination Date in
an aggregate principal amount equal to the aggregate principal amount of the
Revolving Loans so converted ("Term Loans"). The Term Loans may from time to
time be Eurodollar Loans or Base Rate Loans, as determined by the Borrower and
notified to the Administrative Agent in accordance with Section 3.6.

     (b) The Borrower shall repay all outstanding Term Loans on the Term Loan
Maturity Date.

                                  ARTICLE III

                        PROVISIONS RELATING TO ALL LOANS

     SECTION 3.1. Evidence of Loans. (a) Each Bank shall maintain in accordance
with its usual practice an account or accounts evidencing indebtedness of the
Borrower to such Bank resulting from each Loan made by such Bank from time to
time, including, without limitation, the amounts of principal and interest
payable and paid to such Bank from time to time under this Agreement.

     (b) The Administrative Agent shall maintain the Register pursuant to
Section 10.6(d) and a subaccount therein for each Bank, in which shall be
recorded (i) the amount of each Loan made by each Bank through the
Administrative Agent hereunder, the type thereof and each 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 Bank hereunder and (iii)
both the amount of any sum received by the Administrative Agent hereunder from
the Borrower and each Bank's share thereof.

     (c) The entries made in the Register and the accounts of each Bank
maintained pursuant to Section 3.1(a) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amount of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Bank or the Administrative Agent to maintain the Register or any
such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans
actually made to the Borrower by such Bank in accordance with the terms of this
Agreement.

     SECTION 3.2. Fees. (a) The Borrower agrees to pay to the Administrative
Agent for the account of each Bank the Commitment Fee, from the date hereof
until the Revolving Commitment Termination Date payable on the Revolving
Commitment Termination Date.

     (b) The Borrower agrees to pay to the Administrative Agent for the account
of each Bank a draw fee in an amount equal to 0.05% of the principal amount of
each Revolving Loan made by such Bank on a Borrowing Date, payable on such
Borrowing Date.

     (c) The fees payable under Section 3.2(a) shall be calculated by the
Administrative Agent on the basis of a 365- or 366-day year, as the case may be,
for the actual days (including the first day but excluding the last day)
occurring in the period for which such fee is payable.

     (d) The Borrower shall pay to the Administrative Agent, for its own
account, the fees in the amounts and on the dates previously agreed to in
writing by the Borrower and the Administrative Agent.

     SECTION 3.3. Interest. The Borrower shall pay interest on the unpaid
principal amount of each Loan made by each Bank from the date of such Loan until
such principal amount shall be paid in full, at the times and at the rates per
annum set forth below:

     (a) ABR Loans. Each ABR Loan shall bear interest at a rate per annum equal
at all times to the lesser of (i) the ABR plus the Applicable Margin and (ii)
the Highest Lawful Rate, payable


                                       25
<PAGE>
quarterly in arrears on the last day of each March, June, September and December
and on the Revolving Commitment Termination Date or, if the Revolving Loans are
converted pursuant to Section 2.4, the Term Loan Maturity Date.

     (b) LIBOR Rate Loans. Each LIBOR Rate Loan shall bear interest at a rate
per annum equal at all times to, in the case of each LIBOR Rate Loan, the lesser
of (A) the sum of the LIBOR Rate for the applicable Interest Period for such
Loan plus the Applicable Margin and (B) the Highest Lawful Rate, payable on the
last day of such Interest Period and, with respect to Interest Periods of six,
nine or twelve months, on the ninetieth (90th) day after the commencement of the
Interest Period and on each succeeding ninetieth (90th) day during such Interest
Period, and on the Revolving Commitment Termination Date or, if the Revolving
Loans are converted pursuant to Section 2.4, the Term Loan Maturity Date.

     (c) Calculations. Interest that is determined by reference to the ABR shall
be calculated by the Administrative Agent on the basis of a 365- or 366-day
year, as the case may be, for the actual days (including the first day but
excluding the last day) occurring in the period in which such interest is
payable and otherwise shall be calculated by the Administrative Agent on the
basis of a 360-day year for the actual days (including the first day and
excluding the last day) occurring in the period for which such interest is
payable.

     (d) Default Rate. Notwithstanding the foregoing, if all or a portion of (i)
the principal amount of any Loan, (ii) any interest payable thereon, or (iii)
any Commitment Fee or other amount payable hereunder shall not be paid when due
(whether at the stated maturity, by acceleration or otherwise), such overdue
amount shall bear interest, payable from time to time on demand, at a rate per
annum equal to the lesser of (A) the Highest Lawful Rate and (B) the Default
Rate, in each case from the date of such non-payment until such amount is paid
in full (as well after as before judgment).

     (e) Determination Conclusive. Each determination of an interest rate by the
Administrative Agent pursuant to any provisions of this Agreement shall be
conclusive and binding on the Borrower and the Banks in the absence of manifest
error. The Administrative Agent shall, at the request of the Borrower, deliver
to the Borrower a statement showing in reasonable detail the quotations used by
the Administrative Agent in determining the LIBOR Rate.

     SECTION 3.4. Reserve Requirements. (a) The Borrower agrees to pay to each
Bank that requests compensation under this Section 3.4 in accordance with the
provisions set forth in Section 4.8(b), so long as such Bank shall be required
to maintain reserves against "Eurocurrency liabilities" under Regulation D of
the Board (or, so long as such Bank shall be required by the Board or by any
other Governmental Authority to maintain reserves against any other category of
liabilities that includes deposits by reference to which the interest rate on
LIBOR Rate Loans is determined as provided in this Agreement or against any
category of extensions of credit or other assets of such Bank that includes any
LIBOR Rate Loans), an additional amount (determined by such Bank and notified to
the Borrower pursuant to the provisions set forth in Section 4.8(b))
representing such Bank's calculation or, if an accurate calculation is
impracticable, reasonable estimate (using such method of allocation to such
Loans of the Borrower as such Bank shall determine in accordance with Section
4.8(a)) of the actual


                                       26
<PAGE>
costs, if any, incurred by such Bank during the relevant Interest Period as a
result of the applicability of the foregoing reserves to such LIBOR Rate Loans,
which amount in any event shall not exceed the product of the following for each
day of such Interest Period:

          (i) the principal amount of the relevant LIBOR Rate Loans made by such
     Bank outstanding on such day;

          (ii) the difference between (A) a fraction, the numerator of which is
     the LIBOR Rate (expressed as a decimal) applicable to such LIBOR Rate Loan
     (expressed as a decimal), and the denominator of which is one minus the
     maximum rate (expressed as a decimal) at which such reserve requirements
     are imposed by the Board or other Governmental Authority on such date,
     minus (B) such numerator; and

          (iii) a fraction, the numerator of which is one and the denominator of
     which is 360.

     (b) The agreements in this Section 3.4 shall survive the termination of
this Agreement and the payment of all amounts payable hereunder; provided,
however, that in no event shall the Borrower be obligated to reimburse or
compensate any Bank for amounts contemplated by this Section 3.4 for any period
prior to the date that is 90 days before the date upon which such Bank requests
in writing such reimbursement or compensation from the Borrower.

     SECTION 3.5. Interest Rate Determination and Protection. (a) The rate of
interest for each LIBOR Rate Loan shall be determined by the Administrative
Agent two Business Days before the first day of each Interest Period applicable
to such Loan. The Administrative Agent shall give prompt notice to the Borrower
and the Banks of the applicable interest rate determined by the Administrative
Agent for purposes of Sections 3.3(a) and (b) hereof.

     (b) If, with respect to any LIBOR Rate Loans, prior to the first day of an
Interest Period (i) the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the London interbank market, adequate and reasonable
means do not exist for ascertaining the LIBOR Rate for such Interest Period or
(ii) the Administrative Agent shall have received notice from the Majority Banks
that the LIBOR Rate determined or to be determined for such Interest Period will
not adequately and fairly reflect the cost to such Banks (as determined in good
faith and certified by such Banks) of making or maintaining their affected LIBOR
Rate Loans during such Interest Period, the Administrative Agent shall give
facsimile or telephonic notice thereof (with written notice to follow promptly)
to the Borrower and the Banks as soon as practicable thereafter. If such notice
is given, (A) any LIBOR Rate Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (B) any Loans that were to have been
converted on the first day of such Interest Period to LIBOR Rate Loans shall be
continued as ABR Loans and (C) any outstanding LIBOR Rate Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. Until such
notice has been withdrawn by the Administrative Agent, no further LIBOR Rate
Loans shall be made or continued as such, nor shall the Borrower have the right
to convert Loans to LIBOR Rate Loans.


                                       27
<PAGE>
     SECTION 3.6. Voluntary Interest Conversion or Continuation of Loans. (a)The
Borrower may on any Business Day, upon the Borrower's irrevocable oral or
written notice of interest conversion/continuation given by the Borrower to the
Administrative Agent not later than 11:00 A.M. (New York City time) on the third
Business Day prior to the date of the proposed interest conversion or
continuation in the case of a LIBOR Rate Loan, (i) convert Loans of one Type
into Loans of another Type; (ii) convert LIBOR Rate Loans for a specified
Interest Period into LIBOR Rate Loans for a different Interest Period; or (iii)
continue LIBOR Rate Loans for a specified Interest Period as LIBOR Rate Loans
for the same Interest Period-; provided, however, that (A) any conversion of any
LIBOR Rate Loans into LIBOR Rate Loans for a different Interest Period, or into
ABR Loans, or any continuation of LIBOR Rate Loans for the same Interest Period
shall be made on, and only on, the last day of an Interest Period for such LIBOR
Rate Loans; (B) no Loan may be converted into or continued as a LIBOR Rate Loan
by the Borrower so long as an Event of Default has occurred and is continuing,
and (C) no Loan may be converted into or continued as a LIBOR Rate Loan if after
giving effect thereto, Section 2.3 would be contravened. With respect to any
oral notice of interest conversion/continuation given by the Borrower under this
Section 3.6(a), the Borrower shall promptly thereafter confirm such notice in
writing. Each written notice of interest conversion/continuation given by the
Borrower under this Section 3.6(a) and each confirmation of an oral notice of
interest conversion/continuation given by the Borrower under this Section 3.6(a)
shall be in substantially the form of Exhibit B hereto ("Notice of Interest
Conversion/Continuation"). Each such Notice of Interest Conversion/Continuation
shall specify therein the requested (x) date of such interest conversion or
continuation; (y) the Loans to be converted or continued; and (z) if such
interest conversion or continuation is into LIBOR Rate Loans, the duration of
the Interest Period for each such LIBOR Rate Loan. Upon receipt of any such
Notice of Interest Conversion/Continuation, the Administrative Agent shall
promptly notify each Bank thereof. Each Notice of Interest
Conversion/Continuation shall be irrevocable and binding on the Borrower.

     (b) If the Borrower shall fail to deliver to the Administrative Agent a
Notice of Interest Conversion/Continuation in accordance with Section 3.6(a)
hereof, or to select the duration of any Interest Period for the principal
amount outstanding under any LIBOR Rate Loan by 11:00 A.M. (New York City time)
on the third Business Day prior to the last day of the Interest Period
applicable to such Loan in accordance with Section 3.6(a), the Administrative
Agent will forthwith so notify the Borrower and the Banks (provided that the
failure to give such notice shall not affect the conversion referred to below)
and such Loans will automatically, on the last day of the then existing Interest
Period therefor, convert into LIBOR Rate Loans with a one month Interest Period.

     SECTION 3.7. Funding Losses Relating to LIBOR Rate Loans. (a) The Borrower
agrees, without duplication of any other provision under this Agreement, to
indemnify each Bank and to hold each Bank harmless from any loss or expense that
such Bank may sustain or incur as a consequence of (i) default by the Borrower
in payment when due of the principal amount of or interest on any LIBOR Rate
Loan, (ii) default by the Borrower in making a borrowing of, conversion into or
continuation of any LIBOR Rate Loan after the Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (iii)
default by the Borrower in making any prepayment after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (iv) the
making of a prepayment of LIBOR Rate Loans or the conversion of LIBOR Rate Loans
into ABR Loans, on a day that is not the last day of an


                                       28
<PAGE>
Interest Period with respect thereto (excluding any prepayment made pursuant to
Section 3.8) on a day that is not the scheduled maturity date with respect
thereto, including, without limitation, in each case, any such loss or expense
arising from the reemployment of funds obtained by it or from fees payable to
terminate the deposits from which such funds were obtained. The calculation of
all amounts payable to a Bank under this Section 3.7(a) shall be made pursuant
to the method described in Section 4.8(a), but in no event shall such amounts
payable with respect to any LIBOR Rate Loan exceed the amounts that would have
been payable assuming such Bank had actually funded its relevant LIBOR Rate Loan
through the purchase of a deposit bearing interest at the LIBOR Rate in an
amount equal to the amount of such LIBOR Rate Loan and having a maturity
comparable to, with respect to any LIBOR Rate Loan, the relevant Interest
Period, provided, that each Bank may fund each of its LIBOR Rate Loans in any
manner it sees fit, and the foregoing assumption shall be utilized only for the
calculation of amounts payable under this Section 3.7(a).

     (b) The agreements in this Section 3.7 shall survive the termination of
this Agreement and the payment of all amounts payable hereunder; provided,
however, that in no event shall the Borrower be obligated to reimburse or
compensate any Bank for amounts contemplated by this Section 3.7 for amounts
accruing prior to the date that is 90 days prior to the date upon which such
Bank requests in writing such reimbursement or compensation from the Borrower.

     SECTION 3.8. Change in Legality. (a) Notwithstanding any other provision of
this Agreement, if any Bank shall notify the Administrative Agent that it has
determined in good faith that the introduction of or any change in or in the
interpretation or application of any law or regulation by any Governmental
Authority (in each case occurring after the date of this Agreement) makes it
unlawful, or any central bank or other Governmental Authority asserts after the
date of this Agreement that it is unlawful, for any Bank or its applicable
lending office to perform its obligations hereunder to make LIBOR Rate Loans or
to fund or maintain LIBOR Rate Loans hereunder, (i) the obligation of such Bank
to make, or to convert Loans into, or to continue LIBOR Rate Loans as, LIBOR
Rate Loans shall be suspended until the Administrative Agent shall notify the
Borrower that the circumstances causing such suspension no longer exist; (ii)
the Borrower shall, at its option, either prepay in full all LIBOR Rate Loans of
such Bank then outstanding, or convert all such Loans to ABR Loans, on the
respective last days of the then current Interest Periods with respect to such
Loans (or within such earlier period as required by law), accompanied, in the
case of any prepayments, by interest accrued thereon and any amounts payable
under Section 3.7(a). Each Bank agrees that it will use reasonable efforts to
designate a different lending office for the LIBOR Rate Loans due to it affected
by this Section 3.8, if such designation will avoid the illegality described in
this Section 3.8 so long as such designation will not be disadvantageous to such
Bank as determined by such Bank in its sole discretion acting in good faith.

     (b) For purposes of this Section 3.8, a notice to the Borrower (with a copy
to the Administrative Agent) by any Bank pursuant to paragraph (a) above shall
be effective on the date of receipt thereof by the Borrower.

                                 AND PREPAYMENTS

     SECTION 4.1. Increased Costs; Capital Adequacy. (a) If after the date of
this Agreement the adoption of or any change in any law or regulation or in the
interpretation or application thereof by any Governmental Authority or
application thereof or compliance by any Bank with any request or directive
(whether or not having the force of law) from any central bank or other
Governmental Authority made subsequent to the date of this Agreement:

          (i) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Bank that is not otherwise included in the determination of
     the LIBOR Rate hereunder (except for amounts covered by Section 3.4 or any
     other Section hereof); or

          (ii) shall impose on such Bank any other condition;

and the result of any of the foregoing is to increase the actual cost to such
Bank, by an amount that such Bank deems to be material, of making, converting
into, continuing or maintaining LIBOR Rate Loans or to reduce any amount
receivable hereunder in respect thereof, then, in any such case, the Borrower
shall promptly pay such Bank, upon its demand in the manner set forth in Section
4.8(b), any additional amounts, computed by such Bank in accordance with Section
4.8(a), necessary to compensate such Bank for such actual increased cost or
reduced amount receivable that is attributable to Loans or Commitments (to the
extent that such Bank has not already been compensated or reimbursed for such
amounts pursuant to any other provision of this Agreement). If any Bank becomes
entitled to claim any additional amounts pursuant to this Section 4.1(a) from
the Borrower, it shall promptly notify the Borrower, through the Administrative
Agent, of the event by reason of which it has become so entitled in the manner
set forth in Section 4.8(b).

     (b) If any Bank determines in good faith that the introduction of or any
change in or in the interpretation or application by any Governmental Authority
of any law or regulation regarding capital adequacy after the date of this
Agreement or compliance by such Bank or any corporation controlling such Bank
with any law or regulation or any guideline or request from any central bank or
other Governmental Authority (whether or not having the force of law) made or
issued after the date of this Agreement does or shall have the effect, as a
result of such Bank's obligations under this Agreement, of reducing the rate of
return on such Bank's or such corporation's capital to a level below that which
such Bank or such corporation could have achieved but for such change or
compliance (taking into consideration such Bank's or such corporation's policies
with respect to capital adequacy) by an amount deemed by such Bank to be
material, the Borrower shall pay to the Administrative Agent for the account of
such Bank, from time to time as specified by such Bank in the manner set forth
in Section 4.8(b), additional amounts, computed by such Bank in accordance with
Section 4.8(a), sufficient to compensate


                                       30
<PAGE>
such Bank or such corporation in the light of such circumstances, to the extent
that such Bank reasonably determines such reduction in rate of return is
allocable to the existence of such Bank's obligations hereunder.

     (c) The agreements contained in this Section 4.1 shall survive the
termination of this Agreement and the payment of all amounts payable hereunder;
provided, however, that in no event shall the Borrower be obligated to reimburse
or compensate any Bank for amounts contemplated by this Section 4.1 for any
period prior to the date that is 90 days prior to the date upon which such Bank
requests in writing such reimbursement or compensation from the Borrower.

     SECTION 4.2. Pro Rata Treatment and Payments and Computations. (a) Each
Borrowing of Loans by the Borrower from the Banks hereunder, each payment by the
Borrower on account of any commitment or other fee, any reduction of the
Commitments of the Banks and any prepayment on account of principal and interest
on the Loans shall be made pro rata according to the respective Revolving
Percentages of the Banks.

     (b) The Borrower shall make each payment (including each prepayment)
hereunder, whether on account of principal, interest, fees or otherwise, without
setoff or counterclaim, not later than 12:00 Noon (New York City time) on the
day when due in Dollars to the Administrative Agent at the Funding Office in
immediately available funds. The Administrative Agent will promptly thereafter
cause to be distributed like funds relating to the payment of principal,
interest or commitment or other fees (to the extent received by the
Administrative Agent) ratably to the Banks according to the amounts of their
respective Loans and Commitments in respect of which such payment is made, and
like funds relating to the payment of any other amount payable to any Bank (to
the extent received by the Administrative Agent) to such Bank, in each case to
be applied in accordance with the terms of this Agreement.

     (c) Whenever any payment hereunder or under the Notes shall be stated to be
due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be;
provided, however, if such extension would cause payment of interest on or
principal of LIBOR Rate Loans to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (d) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Banks hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Bank on such due date an amount
equal to the amount then due such Bank. If and to the extent the Borrower shall
not have so made such payment in full to the Administrative Agent, each Bank
shall pay to the Administrative Agent on demand an amount equal to the product
of (i) the daily average Federal Funds Effective Rate during such period, times
(ii) the amount of such Bank's Revolving Percentage of such payment, times (iii)
a fraction, the numerator of which is the number of days that elapse from and
including the date such amount is distributed to such Bank to the date on which
such Bank's


                                       31
<PAGE>
Revolving Percentage of such payment shall have become immediately available to
the Administrative Agent and the denominator of which is 360.

     SECTION 4.3. Taxes. (a) Any and all payments by the Borrower hereunder or
under the Loan Documents shall be made free and clear of and without deduction
or withholding for or on account of any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Bank and the Administrative Agent, net
income taxes, branch profits taxes and franchise taxes imposed on it as a result
of a present or former connection between the jurisdiction (or political
subdivision thereof) of the government or taxing authority imposing such tax and
the Administrative Agent or such Bank other than a connection arising solely
from the Administrative Agent or such Bank having executed, delivered or
performed its obligations or received a payment under, or enforced, this
Agreement or any Note (all such non-excluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as "Taxes").
If the Borrower shall be required by law to deduct any Taxes from or in respect
of any sum payable hereunder or under any Note to any Bank or the Administrative
Agent, (i) the sum payable shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 4.3) such Bank or the Administrative Agent (as
the case may be) receives 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 taxation
authority or other authority in accordance with applicable law; provided,
however, that the Borrower shall not be required to increase any such sums
payable to any Bank with respect to any Taxes (i) that are attributable to such
Bank's failure to comply with the requirements of Section 4.3(d) or (ii) that
are United States withholding taxes imposed on sums payable to such Bank at the
time such Bank becomes a party to this Agreement (or maintains a lending
office), except to the extent that any such Bank's assignor (if any) was
entitled, at the time of assignment, to receive additional amounts from the
Borrower with respect to such Taxes pursuant to this Section 4.3. Whenever any
Taxes or Other Taxes (as defined in Section 4.3(b)) are payable by the Borrower,
as promptly as possible thereafter the Borrower shall send to the Administrative
Agent for the account of the relevant Bank or Administrative Agent, as the case
may be, either (A) official tax receipts or notarized copies of such receipts to
such Bank within thirty (30) days after payment of any applicable tax or (B) a
certificate executed by a Responsible Officer of the Borrower confirming that
such Taxes or Other Taxes have been paid, together with evidence of such
payment.

     (b) In addition, the Borrower agrees to pay any present 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 under any Note or from the
execution, delivery or registration of or otherwise with respect to, this
Agreement, any other Loan Document, or the Loans and for which such Bank or the
Administrative Agent (as the case may be) has not been otherwise reimbursed by
the Borrower under this Agreement (hereinafter referred to as "Other Taxes").

     (c) The Borrower will indemnify each Bank and the Administrative Agent for
the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 4.3) paid by such Bank or the Administrative Agent (as the case may be)
and any liability (including penalties, interest and expenses) arising therefrom
or with respect thereto, including, without limitation or duplication,


                                       32
<PAGE>
any incremental taxes, interest or penalties that may become payable by the
Administrative Agent or any Bank as a result of any failure by the Borrower to
pay any Taxes or Other Taxes when due to the appropriate taxing authority or to
remit to any Bank the receipts or other evidence of payment of Taxes or Other
Taxes.

     (d) Each Bank registered in the Register that is not a U.S. Person as
defined in Section 7701(a)(30) of the Code agrees that it will deliver to the
Borrower and the Administrative Agent on the date hereof, or on the date which
it becomes a party to this Agreement, two duly completed copies of United States
Internal Revenue Service Form W-8BEN, W-8ECI W-8EXP or W-8IMY (or other
appropriate corresponding form) or any successor applicable form, as the case
may be. Each such Bank also agrees to deliver to the Borrower and the
Administrative Agent two further copies of the said Form W-8BEN, W-8ECI, W-8EXP,
or W-8IMY or successor applicable forms or other manner of certification, as the
case may be, on or before the date that any such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form or certification previously delivered by it to the Borrower, and
such extensions or renewals thereof as may reasonably be requested by the
Borrower or the Administrative Agent, unless in any such case an event
(including, without limitation, any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required that renders all such forms inapplicable or that would prevent such
Bank from duly completing and delivering any such form with respect to it and
such Bank so advises the Borrower and the Administrative Agent. Each such Bank
shall certify in the case of a Form W-8BEN, W-8ECI, W-8EXP, or W-8IMY that it is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, subject to notification
to the Borrower otherwise pursuant to this Section 4.3(d). In the event that any
such Bank fails to deliver any forms required under this Section 4.3(d), the
Borrower's obligation to pay additional amounts shall be reduced to the amount
that it would have been obligated to pay had such forms been provided.

     (e) If any Taxes or Other Taxes are not correctly or legally asserted and
the Administrative Agent or any Bank determines, in its reasonable discretion,
that it has received a refund of those Taxes or Other Taxes as to which it has
been indemnified by the Borrower, the Administrative Agent or such Bank shall
within 20 days after such refund pay to the Borrower the amount of such refund
to the extent that the Borrower indemnified the Administrative Agent or such
Bank for such Taxes or Other Taxes pursuant to this Section 4.3, net of any
out-of-pocket costs of the Administrative Agent or such Bank and without
interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund); provided, that the Borrower, upon the request of
the Administrative Agent or such Bank, agrees to repay the amount paid over to
the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Bank in the
event the Administrative Agent or such Bank is required to repay such refund to
such Governmental Authority. This paragraph shall not be construed to require
the Administrative Agent or any Bank to make available its tax returns (or any
other information relating to its taxes which it deems confidential) to the
Borrower or any other Person.

     (f) The agreements in this Section 4.3 shall survive the termination of
this Agreement and the payment of all amounts payable hereunder; provided,
however, that (i) in no event shall the Borrower be obligated to reimburse or
compensate any Bank for amounts contemplated by


                                       33
<PAGE>
this Section 4.3 for any period before the date that is 120 days before the date
upon which such Bank requests in writing such reimbursement or compensation from
the Borrower (other than any amounts as to which the ultimate amount of the
reimbursement due could not then be determined) and (ii) nothing contained in
this Section 4.3 shall require the Borrower to pay any amount to any Bank or the
Administrative Agent in addition to that for which it has already reimbursed any
Bank or the Administrative Agent under any other provision of this Agreement.

     SECTION 4.4. Sharing of Payments, Etc. If any Bank (a "Benefitted Bank")
shall at any time receive any payment (other than pursuant to Section 3.4, 3.7,
4.1 or 4.3) of all or part of its Loans owing to it or interest thereon, or
receive any collateral in respect thereof (whether voluntarily or involuntarily,
by setoff, pursuant to events or proceedings of the nature referred to in
Section 8.1(g) or 8.1(h), or otherwise), in a greater proportion than any such
payment to or collateral received by any other Bank, if any, in respect of such
other Bank's Loans owing to it, or interest thereon, such benefitted Bank shall
purchase for cash from the other Banks a participating interest in such portion
of each such other Bank's Loans owing to it or shall provide such other Banks
with the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such benefitted Bank to share the excess payment or benefits
of such collateral or proceeds ratably with each of the Banks; provided,
however, that if all or any portion of such excess payment or benefits is
thereafter recovered from such benefitted Bank, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest. The Borrower agrees that any Bank so purchasing
a participation from another Bank pursuant to this Section 4.4 may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of setoff) with respect to such participation as fully as if such Bank
were the direct creditor of the Borrower in the amount of such participation.

     SECTION 4.5. Optional Termination or Reduction of the Commitments. (a)
Unless previously terminated, the Commitments of the Banks to make Loans shall
terminate on the Revolving Commitment Termination Date.

     (b) The Borrower shall have the right, without penalty or premium, upon at
least three (3) Business Days' irrevocable written notice to the Administrative
Agent (which shall give prompt notice to each Bank), to terminate in whole the
Commitments or permanently, from time to time, to reduce ratably in part the
unused portion of the Commitments, provided that (i) each partial reduction
shall be in the aggregate principal amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof and (ii) no such termination or reduction shall
be permitted if, after giving effect thereto and to any prepayments made under
Section 4.6 by the Borrower on the effective date thereof, the Total Outstanding
Loans then outstanding would exceed the Total Commitments then in effect.

     (c) Each reduction of Commitments pursuant to this Section 4.5 shall be
applied pro rata to the Commitments of each Bank. If at any time, including
after giving effect to any reduction of Commitments pursuant to this Section
4.5, the Total Outstanding Loans exceed the Total Commitments, the Borrower
shall be obligated to prepay the Loans in the amount of such excess. Optional
prepayments of the Loans may not be reborrowed.


                                       34
<PAGE>
     SECTION 4.6. Voluntary Prepayments. The Borrower may, upon written notice
delivered to the Administrative Agent not later than 11:00 A.M. (New York City
time) one (1) Business Day (or in the case of LIBOR Rate Loans, three (3)
Business Days) prior to the date of prepayment stating the aggregate principal
amount of the prepayment and the Loans to be prepaid, prepay the outstanding
principal amounts of such Loans comprising part of the same Borrowing in whole
or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid; provided, however, that losses
incurred by any Bank under Section 3.7 shall be payable with respect to each
such prepayment in the manner set forth in Section 3.7. Any such notice provided
pursuant to this Section 4.6 shall be irrevocable, and the payment amount
specified in such notice shall be due and payable on the prepayment date
described in such notice, together with accrued and unpaid interest on the
amount prepaid. Partial prepayments pursuant to this Section 4.6 with respect to
any Tranche of LIBOR Rate Loans shall be in an aggregate principal amount equal
to the lesser of (a) $10,000,000 or an integral multiple of $1,000,000 in excess
thereof and (b) the aggregate principal amount of such Tranche of LIBOR Rate
Loans then outstanding, as the case may be; provided that no partial prepayment
of any Tranche of LIBOR Rate Loans may be made if, after giving effect thereto,
Section 2.3 would be contravened. Partial prepayments with respect to the ABR
Loans shall be made in an aggregate principal amount equal to the lesser of (i)
$5,000,000 or an integral multiple of $1,000,000 in excess thereof or (ii) the
aggregate principal amount of ABR Loans then outstanding, as the case may be.

     SECTION 4.7. Mandatory Prepayments and Commitment Reductions. (a) If any
Indebtedness for Borrowed Money shall be issued or incurred (including, without
limitation, the issuance of any general mortgage bonds pursuant to the General
Mortgage Indenture or of any first mortgage bonds pursuant to the Mortgage) by
the Borrower or any of its Subsidiaries after the date hereof (other than
Excluded Indebtedness), an amount equal to 100% of the Net Cash Proceeds thereof
shall be applied within one (1) Business Day after such issuance or incurrence
toward the prepayment of the Loans and the reduction of the Commitments as set
forth in Section 4.7(c).

     (b) If the Borrower or any of its Subsidiaries shall receive Net Cash
Proceeds from the True-Up Securitization, within one (1) Business Day after
receipt thereof, the Borrower shall, or shall cause the applicable Subsidiary
to, apply such Net Cash Proceeds toward the prepayment of the Loans and the
reduction of the Commitments as set forth in Section 4.7(c).

     (c) Amounts to be applied in connection with prepayments and Commitment
reductions made pursuant to this Section 4.7 shall be applied (a) at any time
prior to the Revolving Commitment Maturity Date, to reduce permanently the Total
Commitments and (b) at any time on and after the Revolving Commitment
Termination Date, to the prepayment of the Loans outstanding. Any reduction of
the Total Commitments described in the foregoing sentence shall be accompanied
by prepayment of the Loans to the extent, if any, that the Total Outstanding
Loans exceed the amount of the Total Commitments as so reduced. The application
of any prepayment pursuant to this Section 4.7 shall be made, first, to ABR
Loans and, second, to LIBOR Rate Loans. Each prepayment of the Loans under this
Section 4.7 shall be accompanied by accrued interest to the date of such
prepayment on the amount prepaid.


                                       35
<PAGE>
     SECTION 4.8. Mitigation of Losses and Costs. Any Bank claiming
reimbursement from the Borrower under any of Sections 3.4, 3.7, 4.1 and 4.3
hereof shall use reasonable efforts (including, without limitation, if requested
by the Borrower, reasonable efforts to designate a different lending office of
such Bank) to mitigate the amount of such losses, costs, expenses and
liabilities, if such efforts can be made and such mitigation can be accomplished
without such Bank suffering (i) any economic disadvantage for which such Bank
does not receive full indemnity from the Borrower under this Agreement or (ii)
any legal or regulatory disadvantage.

     SECTION 4.9. Determination and Notice of Additional Costs and Other
Amounts. (a) In determining the amount of any claim for reimbursement or
compensation under Sections 3.4, 3.7 and 4.1, each Bank may use any reasonable
averaging, attribution and allocation methods consistent with such methods
customarily employed by such Bank in similar situations.

     (b) Each Bank or, with respect to compensation claimed by it pursuant to
Section 4.3, the Administrative Agent, as the case may be, will (i) use its best
efforts to notify the Borrower through the Administrative Agent (in the case of
each Bank) of any event occurring after the date of this Agreement promptly
after the occurrence thereof and (ii) notify the Borrower through the
Administrative Agent (in the case of each Bank) promptly after such Bank or the
Administrative Agent, as the case may be, becomes aware of any event occurring
after the date of this Agreement, in either case if such event (for purposes of
this Section 4.8(b), a "Triggering Event") will entitle such Bank or the
Administrative Agent, as the case may be, to compensation pursuant to Section
3.4, 3.7, 4.1 or 4.3, as the case may be. Each such notification of a Triggering
Event shall be accompanied by a certificate of such Bank or the Administrative
Agent, as the case may be, setting forth the calculations and justification in
reasonable detail such amount or amounts as shall be necessary to compensate
such Bank or the Administrative Agent, as the case may be, as specified in
Section 3.4, 3.7, 4.1 or 4.3, as the case may be, and certifying that such costs
are generally being charged by such Bank to other similarly situated borrowers
under similar credit facilities, which certificate shall be conclusive absent
manifest error. The Borrower shall pay to the Administrative Agent for the
account of such Bank or to the Administrative Agent for its own account, as the
case may be, the amount shown as due on any such certificate within ten Business
Days after its receipt of the same.

organized and existing as a limited liability company and in good standing under
the laws of its jurisdiction of formation; (ii) is duly authorized or qualified
to do business in and is in good standing in each other jurisdiction in which
the conduct of its business or the ownership or leasing of its Property requires
it to be so authorized or qualified to do business, except where the failure to

aggregate, would not have a Material Adverse Effect, and (iii) has the corporate
or other requisite power and authority to conduct its business, as presently
conducted.

     (b) Organizational Status of Significant Subsidiaries of the Borrower. Each
Significant Subsidiary of the Borrower (i) is validly organized and existing and

aggregate, would not have a Material Adverse Effect and (ii) has the corporate,
partnership or other requisite power and authority to conduct its business, as
presently conducted, except where the failure to have such power and authority,
individually or in the aggregate, would not have a Material Adverse Effect.

     (c) Organizational Powers. The Borrower has the corporate or other
requisite power to execute, deliver and perform and comply with its obligations
under this Agreement, any Notes and the other Loan Documents to which it is a
party. This Agreement has been, and each other Loan Document to which the
Borrower is a party will be, duly executed and delivered on behalf of the
Borrower.

     (d) Authorization, No Conflict, Etc. The borrowings by the Borrower
contemplated by this Agreement, the execution and delivery by the Borrower of
this Agreement and the other Loan Documents to which it is a party and the
performance by the Borrower of its obligations hereunder and thereunder have
been duly authorized by all requisite corporate or other requisite action on the
part of the Borrower and do not and will not (i) violate any law, any order to
which the Borrower or any Restricted Subsidiary of the Borrower is subject of
any court or other


                                       39
<PAGE>
Governmental Authority, or the articles of incorporation or bylaws or other
organizational documents (each as amended from time to time) of the Borrower or
any Restricted Subsidiary of the Borrower; (ii) violate, conflict with, result
in a breach of or constitute (with due notice or lapse of time or both, or any
other condition) a default under, any indenture, loan agreement or other
agreement to which the Borrower or any Restricted Subsidiary of the Borrower is
a party or by which the Borrower or any Restricted Subsidiary of the Borrower,
or any of their respective Property, is bound (except for such violations,
conflicts, breaches or defaults that, individually or in the aggregate, do not
have or would not have a Material Adverse Effect); or (iii) result in, or
require, the creation or imposition of any material Lien upon any of the
Properties of the Borrower or any Significant Subsidiary not permitted under
this Agreement.

     (e) Governmental Approvals and Consents. No authorization or approval or
action by, and no notice to or filing with, any Governmental Authority is
required for the due execution, delivery and performance by the Borrower of, or
for the Borrowings under, this Agreement and the other Loan Documents to which
it is a party, except those that have been obtained.

     (f) Obligations Binding. This Agreement and the other Loan Documents to
which the Borrower is a party are the legal, valid and binding obligations of
the Borrower enforceable against the Borrower in accordance with their
respective terms (assuming due and valid authorization, execution and delivery
of this Agreement by any party other than the Borrower), except as such
enforceability may be (i) limited by the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws relating to or
affecting the enforcement of creditors' rights generally and (ii) subject to the
effect of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

     (g) Use of Proceeds, Margin Stock. The proceeds of the Loans will be used
by the Borrower solely to repay the amounts outstanding under the Existing
Credit Agreement. Neither the Borrower nor any Restricted Subsidiary of the
Borrower is principally engaged in, or has as one of its important activities,
the business of extending credit for the purpose of purchasing or carrying any
Margin Stock, and no part of the proceeds of any Loan made to the Borrower will
be used for any purpose that would violate the provisions of the margin
regulations of the Board.

     (h) Title to Properties. The issued and outstanding Capital Stock owned by
the Borrower of each of its Significant Subsidiaries whether such stock is owned
directly or indirectly through one or more of its Subsidiaries, is owned free
and clear of any Lien. In addition, each of the Borrower and each Significant
Subsidiary has good title to the Properties reflected in the financial
statements referred to in Section 6.1(m) and in any financial statements
delivered pursuant to Section 7.1(a), except for such Properties that have been
disposed of subsequent to the dates of the balance sheets included in such
financial statements and that are no longer used or useful in the conduct of the
business of the Borrower or any Significant Subsidiary or that have been
disposed of pursuant to Section 7.2(b) or (c) or that have been disposed of in
the ordinary course of their respective business, and all such Properties are
free and clear of any Lien except Liens permitted under this Agreement.


                                       40

     (i) Investment Company Act. Neither the Borrower nor any Restricted
Subsidiary of the Borrower is an "investment company" as defined in, or
otherwise subject to regulation under, the Investment Company Act of 1940, as
amended.

     (j) Material Adverse Change. Since December 31, 2003, there has been no
event, development or circumstance that, as of the Closing Date, has or would
reasonably be expected to have a Material Adverse Effect.

     (k) Litigation. As of the Closing Date, there is no litigation, action,
suit, investigation or other legal or governmental proceeding pending or, to the
best knowledge of the Borrower, threatened, at law or in equity, or before or by
any arbitrator or Governmental Authority (i) relating to the transactions under
this Agreement or under any other Loan Document or (ii) in which there is a
reasonable possibility of an adverse decision that would have a Material Adverse
Effect.

     (l) ERISA. Neither the Borrower nor any Significant Subsidiary has incurred
any material liability or deficiency arising out of or in connection with (i)
any Reportable Event or "accumulated funding deficiency" (within the meaning of
Section 412 of the Code or Section 302 of ERISA) with respect to any Plan that
has occurred during the five-year period immediately preceding the date on which
this representation is made or deemed made, (ii) any failure of a Plan to comply
with the applicable provisions of ERISA and the Code, (iii) any termination of a
Single Employer Plan, (iv) any complete or partial withdrawal by the Borrower or
any Commonly Controlled Entity from any Multiemployer Plan or (v) any Lien in
favor of the PBGC or any Plan that has arisen during the five-year period
referred to in clause (i) above. In addition, no Multiemployer Plan is in
Reorganization or is Insolvent, where such Reorganization or Insolvency,
individually or when aggregated with the events described in the first sentence
of this Section 6.1(l), is likely to result in a material liability or
deficiency of the Borrower or any Significant Subsidiary. As used in this
Section 6.1(1), any liability or deficiency shall be deemed not to be "material"
so long as the sum of all liabilities and deficiencies referred to in this
Section 6.1(1) at any one time outstanding, individually and in the aggregate,
is less than $25,000,000.

     (m) Financial Statements. The consolidated financial statements of the
Borrower as of and for the nine months ended September 30, 2004 filed with the
SEC with the Borrower's 10-Q for the period then ended, copies of which have
been delivered to the Banks, present fairly in all material respects the
consolidated financial condition and results of operations of the Borrower, its
Consolidated Subsidiaries and the Unrestricted Subsidiaries as of such date and
for the period then ended, in conformity with, as applicable, GAAP and, except
as otherwise stated therein, consistently applied (in the case of such unaudited
statements, subject to year-end adjustments and the exclusion of detailed
footnotes).

     (n) Accuracy of Information. None of the documents or written information
(excluding estimates, financial projections and forecasts) provided by the
Borrower to the Banks in connection with or pursuant to this Agreement or the
other Loan Documents contains as of the date thereof or will contain as of the
date thereof any untrue statement of a material fact or omits or will omit to
state as of the date thereof a material fact (other than industry-wide risks
normally associated with the types of businesses conducted by the Borrower and
its Subsidiaries)


                                       41
<PAGE>
necessary to make the statements therein, in the light of the circumstances
under which they were made, not materially misleading, as a whole. The
estimates, financial projections and forecasts furnished to the Banks by the
Borrower with respect to the transactions contemplated under this Agreement were
prepared in good faith and on the basis of information and assumptions that the
Borrower believed to be reasonable as of the date of such information; it being
recognized by the Banks that such estimates, financial projections and forecasts
as they relate to future events are not to be viewed as fact and that actual
results during the period or periods covered by such estimates, financial
projections and forecasts may differ from the projected results set forth
therein by a material amount.

     (o) No Violation. The Borrower is not in violation of any order, writ,
injunction or decree of any court or any order, regulation or demand of any
Governmental Authority that, individually or in the aggregate, reasonably could
be expected to have a Material Adverse Effect.

     (p) Subsidiaries. Schedule 6.1(p) attached hereto sets forth each
Significant Subsidiary as of the date hereof. Except as disclosed on Schedule
6.1(p), as of the date hereof the Borrower owns, directly or indirectly through
one or more of its Subsidiaries, all of the outstanding Capital Stock of each
Significant Subsidiary, in each case free and clear of any Liens not permitted
under this Agreement.

     (q) Taxes. The Borrower and each of its Subsidiaries has filed or caused to
be filed all Federal, state and other material tax returns that are required to
be filed and has paid all taxes shown to be due and payable on said returns or
on any assessments made against it or any of its Property and all other taxes,
fees or other charges imposed on it or any of its Property by any Governmental
Authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with GAAP have been provided on the books of the Borrower
or its Subsidiaries), except where the failure to do so could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect;
no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is
being asserted, with respect to any such tax, fee or other charges (other than
any Liens or claims that could not, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect).

     (r) Pledge Agreement. The Pledge Agreement is effective to create in favor
of the collateral agent thereunder, for the benefit of the Banks, a legal, valid
and enforceable security interest in the Collateral described therein and
proceeds thereof. When certificates representing the Collateral are delivered to
the Administrative Agent or when financing statements in appropriate form are
filed with the appropriate office in the State of Texas, upon execution thereof,
the Pledge Agreement shall constitute a fully perfected lien in, and security
interest in, all right, title and interest in the Collateral, prior and superior
in right to any other Person.

     its Consolidated Subsidiaries and the Unrestricted Subsidiaries as of such
     date for the period then ending, and have been prepared in conformity with
     GAAP in a manner consistent with the financial statements referred to in

     institution of (I) any litigation, action, suit or other legal or
     governmental proceeding involving the Borrower or any Restricted Subsidiary
     of the Borrower as to which there is a reasonable possibility of an adverse
     decision that would have a Material Adverse Effect on the Borrower or (II)
     any other final adverse determination in any litigation, action, suit or

     Significant Subsidiary of the Borrower (1) in the True-Up Litigation or (2)
     that would have a Material Adverse Effect or (z) the incurrence by the
     Borrower or any Significant Subsidiary of a material liability or
     deficiency not permitted under this Agreement, or the existence of an event
     that could reasonably be expected to result in a material liability or

     with respect to any Plan, (2) the failure to make any required contribution

     the termination, Reorganization or Insolvency of, any Plan; provided that,
     as used in this clause (z), any liability or deficiency shall be deemed not
     to be "material" so long as the sum of all liabilities and deficiencies
     referred to in this clause (z) at any one time outstanding, individually

     statements delivered pursuant to Section 7.1(a)(i), a certificate signed by
     a Responsible Officer of the Borrower identifying those Subsidiaries which,
     determined as of the date of such financial statements, are Significant
     Subsidiaries and Unrestricted Subsidiaries; and (D) such other information
     relating to the Borrower or its business, properties, condition and
     operations as the Administrative Agent (or any Bank through the
     Administrative Agent) may reasonably request.

Information required to be delivered pursuant to the foregoing Sections
7.1(a)(i), (ii), and (iv)(A) shall be deemed to have been delivered on the date

Administrative Agent (which notice the Administrative Agent will convey promptly
to the Banks) that such information has been posted on the SEC website on the
Internet at sec.gov/edgar/searches.htm or at another website identified in such
notice and accessible by the Banks without charge; provided that (i) such notice
may be included in a certificate delivered pursuant to Section 7.1(a)(iii) and
(ii) the Borrower shall deliver paper copies of such information to the
Administrative Agent, and the Administrative Agent shall deliver paper copies of
such information to any Bank that requests such delivery.


                                       44
<PAGE>
     (b) Use of Proceeds. The Borrower will use the proceeds of any Loan made by
the Banks to it for the purposes set forth in Section 6.1(g), and it will not
use the proceeds of any Loan made by the Banks for any purpose that would
violate the provisions of the margin regulations of the Board. The Borrower will
not, and will not permit any of its Subsidiaries to engage principally, or as
one of its important activities, in the business of extending credit for the
purpose of purchasing or carrying, within the meaning of Regulation U, any
Margin Stock.

     (c) Existence; Laws. The Borrower will and will cause each of its
Significant Subsidiaries to, do or cause to be done all things necessary (i) to
preserve, renew and keep in full force and effect its legal existence and all
rights, licenses, permits and franchises (except to the extent otherwise
permitted by Sections 7.2(c) or 7.2(e)) and (ii) to comply with all laws and
regulations applicable to it, except in each case, where the failure to do so,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect.

     (d) Maintenance of Properties. The Borrower will, and will cause each
Significant Subsidiary to, preserve and maintain all of its Property that is
material to the conduct of its business, provided, however, that nothing in this
Section 7.1(d) shall prevent (a) the Borrower or any of its Significant
Subsidiaries from selling, abandoning or otherwise disposing of any Properties
(including the Capital Stock of any Subsidiary of the Borrower that is not a
Significant Subsidiary), the retention of which in the good faith judgment of
the Borrower or such Significant Subsidiary is inadvisable or unnecessary to the
business of the Borrower and its Subsidiaries, taken as a whole, or the failure
to maintain would not reasonably be expected to have a Material Adverse Effect
or (b) any other transaction that is expressly permitted by the terms of any
other provision of this Agreement.

     (e) Maintenance of Business Line. The Borrower will maintain its
fundamental business of providing services and products in the energy market.

     (f) Books and Records; Access. The Borrower will, and will cause each
Significant Subsidiary to, keep proper books of record and account in which
full, true and correct entries are made of all dealings and transactions in
relation to its business and activities as required by GAAP. The Borrower will,
and will cause each of its Significant Subsidiaries to, at any reasonable time
and from time to time, permit up to six representatives of the Banks designated
by the Majority Banks, or representatives of the Administrative Agent, on not
less than five Business Days' notice, to examine and make copies of and
abstracts from the records and books of account of, and visit the properties of,
the Borrower and each Significant Subsidiary and to discuss the general business
affairs of the Borrower and each of its Significant Subsidiaries with their
respective officers and independent certified public accountants; subject,
however, in all cases to the imposition of such conditions as the Borrower and
each of its Significant Subsidiaries shall deem necessary based on reasonable
considerations of safety and security; provided, however, that neither the
Borrower nor any of its Significant Subsidiaries shall be required to disclose
to any Agent, any Bank or any agents or representatives thereof any information
which is the subject of attorney-client privilege or attorney work-product
privilege properly asserted by the applicable Person to prevent the loss of such
privilege in connection with such information or which is prevented from
disclosure pursuant to a confidentiality agreement with third parties.
Notwithstanding the foregoing, none of the conditions precedent to the exercise
of the right of access described in the preceding sentence that relate to notice


                                       45
<PAGE>
requirements or limitations on the Persons permitted to exercise such right
shall apply at any time when a Default or an Event of Default shall have
occurred and be continuing.

     (g) Insurance. The Borrower will and will cause each of its Significant
Subsidiaries to, maintain insurance with responsible and reputable insurance
companies or associations, or to the extent that the Borrower or such
Significant Subsidiary deems it prudent to do so, through its own program of
self-insurance, in such amounts and covering such risks as is usually carried by
companies engaged in similar businesses, of comparable size and financial
strength and with comparable risks.

     (h) Corporate Rating. The Borrower will deliver to the Administrative Agent
notice of any change by a Rating Agency in its credit or corporate rating
promptly upon the effectiveness of such change.

     SECTION 7.2. Negative Covenants. The Borrower covenants that, so long as
any amount is owing to the Banks hereunder or under any other Loan Documents or
any Bank shall have any Commitment outstanding under this Agreement, the
Borrower will not:

     (a) Financial Ratios.

          (i) Permit at any time the ratio of Consolidated Indebtedness at such
     time to Consolidated Capitalization for the most recently ended
     twelve-month period to exceed 68%.

          (ii) Permit at any time the ratio of Consolidated EBITDA for the most
     recently ended twelve-month period ending during any period set forth below
     to Adjusted Interest Expense for such period to be less than the ratio set
     forth below opposite such period:

     the case may be, Liens in lieu thereof);

          (iv) Liens required to be granted pursuant to "equal and ratable"

     construction, improvement, alteration or repair or the date of commercial
     operation of the assets constructed, improved, altered or repaired, (iii)
     the Indebtedness secured thereby does not exceed the cost of acquiring,
     constructing, improving, altering or repairing such fixed or capital
     assets, as the case may be, and (iv) such Lien shall not apply to any other
     property or assets of the Borrower or of its Restricted Subsidiaries (other
     than repairs, renewals, replacements, additions, accessions, improvements
     and betterments thereto);

          (vi) Liens on Property and repairs, renewals, replacements, additions,

     clauses (i) through (x) above on the same Property previously subject
     thereto; provided that no extension, renewal or refunding of any such Lien

     does not at any time exceed at the time of incurrence of such obligations
     (including any such incurrence resulting from any extension, renewal or
     refunding of such obligations), as to the Borrower and all of its
     Restricted Subsidiaries, 10% of Net Tangible Assets.

     (c) Consolidation, Merger or Disposal of Assets. And will not permit any
Significant Subsidiary to, (i) consolidate with, or merge into or amalgamate
with or into, any other Person; (ii) liquidate, wind up or dissolve itself (or
suffer any liquidation or dissolution); or (iii) convey, sell, transfer, lease
or otherwise dispose of all or substantially all of its Properties to any
Person; provided, however, that nothing contained in this Section 7.2(c) shall
prohibit (A) a merger involving a Subsidiary of the Borrower (including mergers
to reincorporate or change the domicile of such Subsidiary) if any Wholly-Owned
Significant Subsidiary of the Borrower is the surviving entity thereof; (B) the
liquidation, winding up or dissolution of a Significant Subsidiary of the
Borrower if all of the Properties of such Significant Subsidiary are conveyed,
transferred or distributed to the Borrower or a Person that after giving effect
to such transaction is a Wholly-Owned Significant Subsidiary of the Borrower;
(C) the conveyance, sale, transfer or other disposal of all or substantially all
(or any lesser portion) of the Properties of any Significant Subsidiary of the
Borrower to the Borrower or a Person that after giving effect to such
transaction is a Wholly-Owned Significant Subsidiary of the Borrower; or (D) the
transfer of assets in connection with the issuance of Securitization Securities;
provided that, in each case, immediately before and after giving effect to any
such merger, dissolution or liquidation, or conveyance, sale, transfer, lease or
other disposition, no Default or Event of Default shall have occurred and be
continuing.

     (d) Sale of Significant Subsidiary Stock. And will not permit the sale,
assignment, transfer or other disposal of any of the Capital Stock of any
Significant Subsidiary. Notwithstanding the foregoing provisions of Section
7.2(c) or this Section 7.2(e), (x) the Borrower or any Significant Subsidiary
may sell, assign, transfer or otherwise dispose of (i) any of the Capital Stock
of any Significant Subsidiary to the Borrower or to a Wholly-Owned Subsidiary of
the Borrower that constitutes a Significant Subsidiary after giving effect to
such transaction; (ii) the Texas Genco Stock; and (iii) any of the Capital Stock
of any Subsidiary that is not a Significant Subsidiary and (y) any Significant
Subsidiary shall have the right to issue, sell, assign, transfer or otherwise
dispose of for value its preference or preferred stock in one or


                                       48

after giving effect to any such Disposition described in the foregoing clauses
(x) and (y), no Event of Default or Default shall have occurred and be
continuing.

     (e) Agreements Restricting Dividends. And will not permit any Significant
Subsidiary to enter into, incur or permit to exist any agreement or other
consensual arrangement that explicitly prohibits or restricts the payment by any
Significant Subsidiary of dividends or other distributions with respect to any
shares of its Capital Stock; provided that the foregoing shall not prohibit
financial incurrence, maintenance and similar covenants that indirectly have the
practical effect of prohibiting or restricting the ability of a Significant
Subsidiary to make such payments or provisions that require that a certain
amount of capital be maintained, or prohibit the return of capital to
shareholders above certain dollar limits; provided further, that the foregoing
shall not apply to (i) restrictions and conditions imposed by law or by this
Agreement, (ii) restrictions and conditions existing on the date hereof, any
amendment or modification thereof (other than an amendment or modification
expanding the scope of any such restriction or condition and any restrictions or
conditions) that (x) replace restrictions or conditions existing on the date
hereof and (y) are substantially similar to such existing restriction or
condition, (iii) restrictions (including any extension of such restrictions that
does not expand the scope of any such restrictions) existing at the time at
which any such Subsidiary first becomes a Significant Subsidiary, so long as
such restriction was in existence prior to such time in accordance with the
other provisions of this Agreement and was not agreed to or incurred in
contemplation of such change of status and (iv) any restrictions with respect to
a Significant Subsidiary imposed pursuant to an agreement that has been entered
into in connection with a disposition of all or substantially all of the Capital
Stock or assets of such Subsidiary.

     (f) Certain Investments, Loans, Advances, Guarantees and Acquisitions. And
will not permit any of its Significant Subsidiaries to purchase or acquire
(including pursuant to any merger) any Capital Stock, evidence of indebtedness
or other securities of or other interest in (including any option, warrant or
other right to acquire any of the foregoing), make any loans or advances to,
Guarantee any obligations of, or make any investment or other interest in or
capital contribution to any Unrestricted Subsidiary or purchase or otherwise
acquire (in one transaction or a series of transactions) any assets of any
Unrestricted Subsidiary constituting a business unit, (any of the foregoing, an
"Investment") at any time if the aggregate amount of net tangible assets of all
Unrestricted Subsidiaries at such time exceeds, or would exceed as a result of
any such Investment, 10% of the Net Tangible Assets.

     SECTION 7.3. Borrower's Accounting Reorganization.

     (a) The Borrower has advised the Banks that it is considering an accounting
reorganization of its operations and corporate structure that would involve the
extinguishment of a negative retained earnings balance and the restatement of
its assets and its liabilities to their fair values (the "Accounting
Reorganization").

     (b) In the event that the Accounting Reorganization occurs, the Borrower
shall notify the Administrative Agent thereof and notwithstanding any of the
terms, conditions or provisions of this Agreement or the other Loan Documents to
the contrary, compliance with the financial covenants, standards, terms and
conditions in this Agreement and the Loan Documents shall be


                                       49
<PAGE>
based on the performance by the Borrower and its Subsidiaries therewith as
though the Accounting Reorganization had not occurred and the Borrower shall
deliver, together with the certificates required under Section 7.1(a)(iii), pro
forma financial statements prepared on the basis that the Accounting
Reorganization had not occurred.

     (c) In addition, the Borrower may request various amendments to the
covenants, representations, Events of Defaults and the other standards, terms
and conditions of this Agreement and the Loan Documents. If so requested, the
Borrower and the Banks agree to enter into negotiations in order to amend such
provisions (with the agreement of the Majority Banks or, if required by Section
10.1, all of the Banks) so as to equitably reflect such changes with the desired
result that the criteria for evaluating any of the Borrower's and its Restricted
Subsidiaries' financial condition shall be the same after the Accounting
Reorganization as if such Accounting Reorganization had not occurred. Each of
the Banks agrees to consider these requests and proposed amendments in good
faith and agrees not to unreasonably withhold or delay its consent to such
amendments. Unless and until such provisions have been so amended, Section
7.3(b) shall govern the Borrower's compliance with this Agreement and the Loan
Documents.

Agent; or

     (c) Breach of Representation or Warranty. Any representation or warranty by

have been made; or

     SECTION 8.2. Cancellation/Acceleration. If at any time and for any reason
(whether within or beyond the control of any party to this Agreement):

     (a) either of the Events of Default specified in Section 8.1(g) or 8.1(h)
occurs with respect to the Borrower, then automatically:

          (i) the Commitments shall immediately be cancelled; and

          (ii) all Loans made hereunder, all unpaid accrued interest or fees and

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

     SECTION 9.1. Appointment. Each Bank hereby irrevocably designates and
appoints Citibank, N.A. as the Administrative Agent of such Bank under this
Agreement and the other Loan Documents, and each such Bank irrevocably
authorizes Citibank, N.A., as the Administrative Agent for such Bank, to take
such action on its behalf under the provisions of this Agreement and the other
Loan Documents and to exercise such powers and perform such duties as are
expressly delegated to the Administrative Agent by the terms of this Agreement
and the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, (a) the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent and (b) the other Agents and the Lead Arrangers shall not
have any duties or responsibilities hereunder, or any fiduciary relationship
with any Bank, and no implied covenants, functions, responsibilities, duties,


                                       53
<PAGE>
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the other Agents or the Lead Arrangers.

     SECTION 9.2. Delegation of Duties. The Administrative Agent may execute any
of its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

     SECTION 9.3. Exculpatory Provisions. Neither any Agent nor any of their
respective officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (b) responsible in any manner to any of the Banks for any
recitals, statements, representations or warranties made by the Borrower or any
officer thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent or any other Agent under or in
connection with, this Agreement or any other Loan Document or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any Note or any other Loan Document or for any failure of the
Borrower to perform its obligations hereunder or thereunder. The Agents shall
not be under any obligation to any Bank to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Borrower.

     SECTION 9.4. Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
note, writing, resolution, notice, consent, certificate, affidavit, letter,
facsimile, telex or teletype message, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to the Borrower),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note or any loan
account in the Register as the owner thereof for all purposes unless a written
notice of assignment, negotiation or transfer thereof shall have been filed with
the Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority Banks (or, if so specified by this Agreement, all Banks) as it deems
appropriate or it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense that may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement and the other Loan Documents in accordance with a request of the
Majority Banks (or, if so specified by this Agreement, all Banks), and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Banks and all future holders of the amounts owing hereunder.

     SECTION 9.5. Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless


                                       54
<PAGE>
the Administrative Agent has received notice from a Bank or the Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
notice thereof to the Banks. The Administrative Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Majority Banks; provided that unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable in the
best interests of the Banks.

     SECTION 9.6. Non-Reliance on Administrative Agent and Other Banks. Each
Bank expressly acknowledges that neither the Agents nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or Affiliates have
made any representations or warranties to it and that no act by any Agent
hereinafter taken, including any review of the affairs of the Borrower, shall be
deemed to constitute any representation or warranty by any Agent to any Bank.
Each Bank represents to the Agents that it has, independently and without
reliance upon any Agent or any other Bank, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrower and made its own decision to make
its Loans hereunder and enter into this Agreement. Each Bank also represents
that it will, independently and without reliance upon any Agent or any other
Bank, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement and the other Loan
Documents, and to make such investigation as it deems necessary to inform itself
as to the business, operations, property, financial and other condition and
creditworthiness of the Borrower. Except for notices, reports and other
documents expressly required to be furnished to the Banks by the Administrative
Agent hereunder, the Administrative Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Borrower that may come into the
possession of the Administrative Agent or any of its officers, directors,
employees, Administrative Agent, attorneys-in-fact or Affiliates.

     SECTION 9.7. Indemnification. The Banks agree to indemnify the Agents and
the Lead Arrangers in their respective capacities as such (to the extent not
reimbursed by the Borrower and without limiting the obligation of the Borrower
to do so), ratably according to their respective applicable Revolving
Percentages in effect on the date on which indemnification is sought under this
Section 9.7, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (including, without limitation, at
any time following the payment of all amounts owing hereunder and the
termination of the Commitments) be imposed on, incurred by or asserted against
the Agents or the Lead Arrangers, as the case may be, in any way relating to or
arising out of this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agents or
the Lead Arrangers, as the case may be, under or in connection with any of the
foregoing; provided that no Bank shall be liable for the payment of any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agents' or
the Lead


                                       55
<PAGE>
Arrangers', as the case may be, gross negligence or willful misconduct. The
agreements in this Section 9.7 shall survive the payment of all amounts payable
hereunder.

     SECTION 9.8. Agent in Its Individual Capacity. Each Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrower as though such Agent were not an Agent
hereunder and under the other Loan Documents. With respect to its Loans made or
renewed by it and its Commitment hereunder, each Agent shall have the same
rights and powers under this Agreement and the other Loan Documents as any Bank
and may exercise the same as though it were not an Agent, and the terms "Bank"
and "Banks" shall include the each Agent in its individual capacity.

     SECTION 9.9. Successor Administrative Agent. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Banks and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this Agreement and the other Loan Documents, then the Majority Banks shall
appoint from among the Banks a successor agent for the Banks, which successor
agent shall be approved by the Borrower, whereupon such successor agent shall
succeed to the rights, powers and duties of the Administrative Agent, and the
term "Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Agent or any of the parties to
this Agreement or any holders of any amounts payable hereunder; provided that if
an Event of Default has occurred and is continuing, no consent of the Borrower
shall be required. If a successor Administrative Agent shall not have been so
appointed within said 30-day period, the Administrative Agent may then appoint a
successor Administrative Agent who shall be a financial institution engaged or
licensed to conduct banking business under the laws of the United States with an
office in New York City and that has total assets in excess of $500,000,000 and
who shall serve as Administrative Agent until such time, if any, as an
Administrative Agent shall have been appointed as provided above. After any
retiring Administrative Agent's resignation or removal as Administrative Agent,
the provisions of this Article X shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Loan Documents.

     Notwithstanding anything to the contrary contained herein, no Bank
identified as an "Agent", "Arranger" or "Global Coordinator" other than the
Administrative Agent, shall have the right, power, obligation, liability,
responsibility or duty under this Agreement or any Loan Document other than
those applicable to all Banks as such. Without limiting the foregoing, none of
the Banks so identified shall have or be deemed to have any fiduciary
relationship with any Bank. Each Bank acknowledges that it has not relied, and
will not rely, on any of the Banks so identified in deciding to enter into this
Agreement or not taking action hereunder.

                                    ARTICLE X

                                  MISCELLANEOUS

     SECTION 10.1. Amendments and Waivers. Neither this Agreement, any Note, any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except pursuant to an instrument or instruments in
writing executed in accordance with


                                       56
<PAGE>
the provisions of this Section 10.1. The Majority Banks may, or, with the
written consent of the Majority Banks, the Administrative Agent may, from time
to time, (a) enter into with the Borrower written amendments, supplements or
modifications hereto and to any Notes and the other Loan Documents for the
purpose of adding any provisions to this Agreement or any Notes or the other
Loan Documents or changing in any manner the rights of the Banks or of the
Borrower hereunder or thereunder or (b) waive, on such terms and conditions as
the Majority Banks or the Administrative Agent, as the case may be, may specify
in such instrument, any of the requirements of this Agreement or any Notes or
the other Loan Documents or any Default or Event of Default and its
consequences; provided, however, that no such waiver and no such amendment,
supplement or modification shall:

          (i) reduce the amount or extend the scheduled date of maturity of any
     Note or Loan, or reduce the stated rate of any interest or fee (including
     the prepayment premium provided for in Section 4.6) payable hereunder or
     extend the scheduled date of any payment thereof, or increase the amount or
     extend the expiration date of any Bank's Commitments, in each case without
     the consent of each Bank directly affected thereby;

          (ii) amend, modify or waive any provision of this Section or of
     Section 4.2 in a manner that would alter the pro rata sharing of payments
     required thereby, or reduce the percentage specified in the definition of
     Majority Banks, or consent to the assignment or transfer by the Borrower of
     any of its respective rights and obligations under this Agreement and the
     other Loan Documents or release all or substantially all of the Collateral,
     in each case without the written consent of all the Banks; or

          (iii) amend, modify or waive any provision of Article IX without the
     written consent of the then Administrative Agent.

          Any such waiver and any such amendment, supplement or modification
shall apply equally to each of the Banks and shall be binding upon the Borrower,
the Banks, the Administrative Agent and all future holders of the amounts
payable hereunder. In the case of any waiver (to the extent specified therein),
the Borrower, the Banks, and the Administrative Agent shall be restored to their
former position and rights hereunder and under any outstanding Notes and any
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing, but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent
thereon.

     SECTION 10.2. Notices. Unless otherwise expressly provided herein, all
notices, requests and demands to or upon the respective parties hereto to be
effective shall be in writing (including by facsimile followed by any original
sent by mail or delivery), and, shall be deemed to have been duly given or made

prepaid, or, in the case of telecopy notice, when received, addressed as follows

Schedule 1.1(A) in the case of the other parties hereto, or to such other
address as may be hereafter notified by the respective parties hereto and any

     SECTION 10.3. No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of the Administrative Agent or any Bank, any
right, remedy, power or privilege hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

     SECTION 10.4. Survival of Representations and Warranties. All
representations and warranties made hereunder and in any document, certificate
or statement delivered pursuant hereto or in connection herewith shall survive

     SECTION 10.5. Payment of Expenses and Taxes; Indemnity. The Borrower agrees
(a) to pay all reasonable out-of-pocket expenses of the Global Coordinators
associated with the syndication of the Facility, (b) to pay or reimburse the

costs and expenses incurred in connection with the development, preparation,
negotiation and execution and delivery of, and any amendment, supplement or
modification to, this Agreement and any Notes and the other Loan Documents and
any other documents prepared in connection herewith or therewith, and the
consummation and administration of the transactions contemplated hereby and
thereby, including, without


                                       58
<PAGE>
limitation, the reasonable fees and disbursements of Simpson Thacher & Bartlett
LLP, special counsel to the Administrative Agent (but excluding the fees or
expenses of any other counsel), (c) to pay or reimburse the Administrative Agent
for all its costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, any Notes, the other Loan
Documents and any such other documents, including, without limitation, the
reasonable fees and disbursements of the special counsel to the Administrative
Agent, (d) to pay or reimburse each Bank for all its costs and expenses incurred
in connection with the enforcement, or at any time after the occurrence and
during the continuance of a Default or an Event of Default the preservation, of
any rights under this Agreement, any Notes, the other Loan Documents and any
such other documents, including, without limitation, the reasonable fees and
disbursements of counsel to such Bank, (e) without duplication of any other
provision contained in this Agreement or any Notes, to pay, indemnify, and hold
each Bank and the Administrative Agent harmless from, any and all recording and
filing fees, if any, and any and all liabilities (for which each Bank has not
been otherwise reimbursed under this Agreement) with respect to, or resulting
from any delay in paying, stamp, excise and other taxes, if any, that may be
payable or determined to be payable in connection with the execution and
delivery of, or consummation or administration of any of the transactions
contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, any Notes, the other Loan
Documents and any such other documents, and (f) without duplication of any other
provision contained in this Agreement or any Notes, to pay, indemnify, and hold
each Global Coordinator, each Lead Arranger, each Bank and each Agent together
with their respective directors, officers, employees, agents, trustees, advisors
and affiliates (collectively, "Indemnified Persons") harmless from and against,
any and all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever (including without limitation, all fees and expenses of counsel to
any indemnified person) with respect to the execution, delivery, enforcement,
performance and administration of this Agreement, any Notes or the other Loan
Documents, the transactions contemplated by this Agreement, any Notes or the
other Loan Documents, or the use, or proposed use, of proceeds of the Loans (all
the foregoing in this clause (f), collectively, the "Indemnified Liabilities");
provided that the Borrower shall have no obligation hereunder to an Indemnified
Person with respect to Indemnified Liabilities arising from the gross negligence
or willful misconduct of such Indemnified Person, AND PROVIDED FURTHER THAT IT
IS THE INTENTION OF THE BORROWER TO INDEMNIFY THE INDEMNIFIED PERSONS AGAINST
THE CONSEQUENCES OF THEIR OWN NEGLIGENCE. The agreements in this Section 10.5
shall survive repayment of the Loans and all other amounts payable hereunder.

     SECTION 10.6. Effectiveness, Successors and Assigns, Participations;
Assignments. (a) This Agreement shall become effective on the date hereof and
thereafter shall be binding upon and inure to the benefit of the Borrower, the
Banks, the Administrative Agent, all future holders of the Loans and their
respective successors and assigns, except that the Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of each Bank.

     (b) Any Bank may, in the ordinary course of its business and in accordance
with applicable law, at any time sell to one or more banks or other financial
institutions or Bank Affiliates (a "Participant") participating interests in any
Loan owing to such Bank, any Note held by such Bank, any Commitment of such Bank
or any other interest of such Bank hereunder and


                                       59
<PAGE>
under the other Loan Documents. In the event of any such sale by a Bank of a
participating interest to a Participant, such Bank's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Bank shall remain solely responsible for the performance thereof, such Bank
shall remain the holder of any such Loan and Commitment or other interest for
all purposes under this Agreement and the other Loan Documents, the Borrower and
the Administrative Agent shall continue to deal solely and directly with such
Bank in connection with such Bank's rights and obligations under this Agreement
and the other Loan Documents and except with respect to the matters set forth in
Section 10.1, the amendment of which requires the consent of all of the Banks,
the participation agreement between the selling Bank and the Participant may not
restrict such Bank's voting rights hereunder. The Borrower agrees that each
Participant, to the extent provided in its participation, shall be entitled to
the benefits of Sections 3.4, 3.7, 4.1 and 4.3 with respect to its participation
in the Commitments and the Loans outstanding from time to time; provided that
(i) no Participant shall be entitled to receive any greater amount pursuant to
such Sections than the selling Bank would have been entitled to receive in
respect of the amount of the participation sold by such selling Bank to such
Participant had no such sale occurred and (ii) each such sale of participating
interests shall be to a "qualified purchaser", as such term is defined under the
Investment Company Act of 1940. Except as expressly provided in this Section
10.6(b), no Participant shall be a third-party beneficiary of or have any rights
under this Agreement or under any of the other Loan Documents.

     (c) Except as set forth below, the Banks shall be permitted to assign all
or a portion of their Loans and Commitments to one or more financial
institutions ("Purchasing Banks") with the consent, not to be unreasonably
withheld, of (a) the Borrower, unless (i) the Purchasing Bank is a Bank or a
Bank Affiliate or (ii) an Event of Default has occurred and is continuing and
(b) the Administrative Agent, unless the assignment is from a Bank to its Bank
Affiliate pursuant to an Assignment and Acceptance, substantially in the form of
Exhibit C (an "Assignment and Acceptance"), executed by such Purchasing Bank and
such transferor Bank (and by the Borrower and the Administrative Agent, as
applicable) and delivered to the Administrative Agent for its acceptance and
recording in the Register; provided that (i) such Purchasing Bank is a
"qualified purchaser" as defined under the Investment Company Act of 1940, (ii)
each such sale shall be of a uniform, and not a varying, percentage of all
rights and obligations under and in respect of the Commitment of such Bank,
(iii) each such sale shall be in an aggregate amount of not less than $5,000,000
(or such lesser amount representing the entire Commitment of such transferor
Bank) if such sale is not to an existing Bank and (iv) after giving effect to
such sale, the transferor Bank shall (to the extent that it continues to have
any Commitment hereunder) have a Commitment of not less than $5,000,000,
provided that such amounts shall be aggregated in respect of each Bank and its
Bank Affiliates, if any. Upon such execution, delivery, acceptance and
recording, from and after the effective date determined pursuant to such
Assignment and Acceptance (the "Transfer Effective Date"), (i) the Purchasing
Bank thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Bank hereunder
with the Commitments as set forth therein and (ii) the transferor Bank
thereunder shall, to the extent provided in such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of a transferor
Bank's rights and obligations under this Agreement, such transferor Bank shall
cease to be a party hereto). Such Assignment and Acceptance shall be deemed to
amend this Agreement to the extent, and only to the extent, necessary to reflect
the


                                       60
<PAGE>
addition of such Purchasing Bank and the resulting adjustment of Revolving
Percentages arising from the purchase by such Purchasing Bank of all or a
portion of the rights and obligations of such transferor Bank under this
Agreement. On or prior to the Transfer Effective Date determined pursuant to
such Assignment and Acceptance, (i) appropriate entries shall be made in the
accounts of the transferor Bank and the Register evidencing such assignment and
releasing the Borrower from any and all obligations to the transferor Bank in
respect of the assigned Loan or Loans and (ii) appropriate entries evidencing
the assigned Loan or Loans shall be made in the accounts of the Purchasing Bank
and the Register as required by Section 3.1 hereof. In the event that any Notes
have been issued in respect of the assigned Loan or Loans, such Notes shall be
marked "cancelled" and surrendered by the transferor Bank to the Administrative
Agent for return to the Borrower.

     (d) The Administrative Agent shall maintain at its address referred to in
Section 10.2 a copy of each Assignment and Acceptance delivered to it and a
register (the "Register") for the recordation of the names and addresses of the
Banks and the Commitments of, and principal amount of the Loans owing to, each
Bank from time to time. To the extent permitted by applicable law, the entries
in the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Banks may (and, in the case of any
Loan or other obligations hereunder not evidenced by a Note, shall) treat, each
Person whose name is recorded in the Register as the owner of a Loan or other
obligation hereunder as the owner thereof for all purposes of this Agreement and
the other Loan Documents, notwithstanding any notice to the contrary. Any
assignment of any Loan or other obligation hereunder not evidenced by a Note
shall be effective only upon appropriate entries with respect thereto being made
in the Register. The Register shall be available for inspection by the Borrower
or any Bank at any reasonable time and from time to time upon reasonable prior
notice.

     (e) Upon its receipt of an Assignment and Acceptance executed by a
transferor Bank and Purchasing Bank (and, in the case of a Purchasing Bank that
is not then a Bank Affiliate, by the Borrower and the Administrative Agent)
together with payment to the Administrative Agent of a registration and
processing fee of $3,500, the Administrative Agent shall promptly accept such
Assignment and Acceptance on the Transfer Effective Date determined pursuant
thereto, record the information contained therein in the Register and give
notice of such acceptance and recordation to the Banks and the Borrower.

     (f) Each of the Banks and the Administrative Agent agrees to exercise its
best efforts to keep, and to cause any third party recipient of the information
described in this Section 10.6(f) to keep, any information delivered or made
available by the Borrower to it (including any information obtained pursuant to
Section 7.1), confidential from anyone other than Persons employed or retained
by such party who are or are expected to become engaged in evaluating,
approving, structuring or administering the transactions contemplated hereunder;
provided that nothing shall prevent any Bank or the Administrative Agent from
disclosing such information (i) to any other Bank or any Affiliate of any Bank,
(ii) pursuant to subpoena or upon the order of any court or administrative
agency, (iii) upon the request or demand of any Governmental Authority having
jurisdiction over such Bank, (iv) if such information has been publicly
disclosed, (v) to the extent reasonably required in connection with any
litigation to which either the Administrative Agent, any Bank, the Borrower or
their respective Affiliates may be a party, (vi) to the extent reasonably
required in connection with the exercise of any remedy hereunder,


                                       61
<PAGE>
(vii) to the Administrative Agent's or such Bank's, as the case may be, legal
counsel, independent auditors and other professional advisors, or (viii) to any
actual or proposed Participant, Purchasing Bank or pledgee (each, a
"Transferee") that has agreed in writing to be bound by the provisions of this
Section 10.6(f). To the extent permitted by applicable law, in the event that
any Bank or the Administrative Agent is legally requested or required to
disclose any confidential information pursuant to clause (ii), (iii), or (v) of
this Section 10.6(f), such party shall promptly notify the Borrower of such
request or requirement prior to disclosure so that Borrower may seek an
appropriate protective order and/or waive compliance with the terms of this
Agreement. If, however, in the opinion of counsel for such party, such party is
nonetheless, in the absence of such order or waiver, compelled to disclose such
confidential information or otherwise stand liable for contempt or suffer
possible censure or other penalty or liability, then such party may disclose
such confidential information without liability to the Borrower; provided,
however, that such party will use its best efforts to minimize the disclosure of
such information. Subject to the exceptions above to disclosure of information,
each of the Banks and the Administrative Agent agrees that it shall not publish,
publicize, or otherwise make public any information regarding this Agreement or
the transactions contemplated hereby without the written consent of the
Borrower, in its sole discretion.

     (g) If, pursuant to this Section 10.6, any interest in this Agreement or
any Loan is transferred to any Transferee that is organized under the laws of
any jurisdiction other than the United States or any state thereof, the
transferor Bank shall cause such Transferee, concurrently with the effectiveness
of such transfer, (i) to deliver to the transferor Bank (and, in the case of any
Purchasing Bank registered in the Register, the Administrative Agent and the
Borrower) either U.S. Internal Revenue Service Form W-8BEN or U.S. Internal
Revenue Service Form W-8ECI, or successor applicable forms (wherein such
Transferee claims entitlement to complete exemption from U.S. federal
withholding tax on all interest payments hereunder) and (ii) to agree (for the
benefit of the transferor Bank, the Administrative Agent and the Borrower) to
deliver to the transferor Bank (and, in the case of any Purchasing Bank
registered in the Register, the Administrative Agent and Borrower) a new Form
duly executed and completed W-8BEN or W-8ECI, or successor applicable forms or
other manner of certification, as the case may be, upon the expiration or
obsolescence of any previously delivered form in accordance with applicable U.S.
laws and regulations and amendments, unless in any such case any change in
treaty, law or regulation has occurred prior to the date on which any such
delivery would otherwise be required that renders all such forms inapplicable or
that would prevent such Transferee from duly completing and delivering any such
form with respect to it and such Transferee so advises the transferor Bank (and,
in the case of any Purchasing Bank registered in the Register, the
Administrative Agent and the Borrower).

     (h) Any Bank may at any time pledge or assign a security interest in all or
any portion of its rights under this Agreement to secure obligations of such
Bank, including any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment
of a security interest; provided that no such pledge or assignment of a security
interest shall release a Bank from any of its obligations hereunder or
substitute any such pledgee or Purchasing Bank for such Bank as a party hereto.
The Borrower hereby agrees that, upon request of any Bank at any time and from
time to time after the Borrower has made its initial Borrowing hereunder, the
Borrower shall provide to such Bank, at the Borrower's own


                                       62
<PAGE>
expense, a promissory note, substantially in the form of Exhibit D evidencing
the Loans owing to such Bank.

     SECTION 10.7. Setoff. In addition to any rights and remedies of the Banks
provided by law, each Bank shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder or under the Loans to which it is a party (whether at the
stated maturity, by acceleration or otherwise) to setoff and appropriate and
apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Bank or any branch or agency thereof to or for the credit or the
account of the Borrower. Each Bank agrees promptly to notify the Borrower and
the Administrative Agent after any such setoff and application made by such
Bank, provided that the failure to give such notice shall not affect the
validity of such setoff and application.

     SECTION 10.8. Counterparts. This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts, and all
of said counterparts taken together shall be deemed to constitute one and the
same instrument. A set of the copies of this Agreement signed by all the parties
shall be maintained with Borrower and the Administrative Agent.

     SECTION 10.9. Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

     SECTION 10.10. Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the Administrative Agent and the Banks
with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by the Administrative Agent or any
Bank relative to the subject matter hereof not expressly set forth or referred
to herein or in the other Loan Documents.

     SECTION 10.11. GOVERNING LAW. (a) THIS AGREEMENT AND ANY NOTES OR OTHER
LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS
AGREEMENT AND ANY NOTES AND ANY OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

          (b) Notwithstanding anything in Section 10.11(a) to the contrary,
nothing in this Agreement or in any Note or any other Loan Documents shall be
deemed to constitute a waiver of any rights which any Bank may have under
applicable federal law relating to the amount of interest which any Bank may
contract for, take, receive or charge in respect of any Loans, including any
right to take, receive, reserve and charge interest at the rate allowed by the
laws of the state where such Bank is located. To the extent that Texas law is
applicable to the determination of the Highest Lawful Rate, the Banks and the
Borrower agree that (i) if


                                       63
<PAGE>
Chapter 303 of the Texas Finance Code, as amended, is applicable to such
determination, the weekly rate ceiling (formerly known as the indicated (weekly)
rate ceiling in Article 1.04, Subtitle 1, Title 79, of the Revised Civil
Statutes of Texas, as amended) as computed from time to time shall apply,
provided that, to the extent permitted by such Article, the Administrative Agent
may from time to time by notice to the Borrower revise the election of such
interest rate ceiling as such ceiling affects the then current or future
balances of the Loans; and (ii) the provisions of Chapter 346 of the Texas
Finance Code, as amended (formerly found in Chapter 15 of Subtitle 3, Title 79,
of the Revised Civil Statutes of Texas, 1925, as amended) shall not apply to
this Agreement or any Note issued hereunder.

     SECTION 10.12. Submission to Jurisdiction; Waivers. The Borrower hereby
irrevocably and unconditionally:

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

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

     (c) agrees that service of process in any such action or proceeding may be
effected by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid to the Borrower at its
address set forth in Section 10.2 or at such other address of which the
Administrative Agent shall have been notified pursuant thereto;

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

     (e) waives, to the maximum extent permitted by applicable law, any right it
may have to claim or recover in any legal action or proceeding any special,
exemplary, punitive or consequential damages.

     SECTION 10.13. Acknowledgments. The Borrower hereby acknowledges that:

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

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

     (c) no joint venture exists among the Banks or among the Borrower and the
Banks.


                                       64
<PAGE>
     SECTION 10.14. Limitation on Agreements. All agreements between the
Borrower, the Administrative Agent or any Bank, whether now existing or
hereafter arising and whether written or oral, are hereby expressly limited so
that in no contingency or event whatsoever, whether by reason of demand being
made in respect of an amount due under any Loan Document or otherwise, shall the
amount paid, or agreed to be paid, to the Administrative Agent or any Bank for
the use, forbearance, or detention of the money to be loaned under this
Agreement, any Notes or any other Loan Document or otherwise or for the payment
or performance of any covenant or obligation contained herein or in any other
Loan Document exceed the Highest Lawful Rate. If, as a result of any
circumstances whatsoever, fulfillment of any provision hereof or of any of such
documents, at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by applicable usury law, then,
ipso facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if, from any such circumstance, the Administrative Agent or any
Bank shall ever receive interest or anything that might be deemed interest under
applicable law that would exceed the Highest Lawful Rate, such amount that would
be excessive interest shall be applied to the reduction of the principal amount
owing on account of such Bank's Loans or the amounts owing on other obligations
of the Borrower to the Administrative Agent or any Bank under any Loan Document
and not to the payment of interest, or if such excessive interest exceeds the
unpaid principal balance of such Bank's Loans and the amounts owing on other
obligations of the Borrower to the Administrative Agent or any Bank under any
Loan Document, as the case may be, such excess shall be refunded to the
Borrower. All sums paid or agreed to be paid to the Administrative Agent or any
Bank for the use, forbearance or detention of the indebtedness of the Borrower
to the Administrative Agent or any Bank shall, to the fullest extent permitted
by applicable law, be amortized, prorated, allocated and spread throughout the
full term of such indebtedness until payment in full of the principal (including
the period of any renewal or extension thereof) so that the interest on account
of such indebtedness shall not exceed the Highest Lawful Rate. Notwithstanding
anything to the contrary contained in any Loan Document, it is understood and
agreed that if at any time the rate of interest that accrues on the outstanding
principal balance of any Loan shall exceed the Highest Lawful Rate, the rate of
interest that accrues on the outstanding principal balance of any Loan shall be
limited to the Highest Lawful Rate, but any subsequent reductions in the rate of
interest that accrues on the outstanding principal balance of any Loan shall not
reduce the rate of interest that accrues on the outstanding principal balance of
any Loan below the Highest Lawful Rate until the total amount of interest
accrued on the outstanding principal balance of any Loan equals the amount of
interest that would have accrued if such interest rate had at all times been in
effect. The terms and provisions of this Section 10.14 shall control and
supersede every other provision of all Loan Documents.

     SECTION 10.15. Removal of Bank. Notwithstanding anything herein to the
contrary, the Borrower may, at any time in its sole discretion, remove any Bank
upon 15 Business Days' written notice to such Bank and the Administrative Agent
(the contents of which notice shall be promptly communicated by the
Administrative Agent to each other Bank), such removal to be effective at the
expiration of such 15-day notice period; provided, however, that no Bank may be
removed hereunder at a time when an Event of Default shall have occurred and be
continuing. Each notice by the Borrower under this Section 10.15 shall
constitute a representation by the Borrower that the removal described in such
notice is permitted under this Section 10.15. Concurrently with such removal,
the Borrower shall pay to such removed Bank all amounts owing to such Bank
hereunder and under any other Loan Document in immediately available


                                       65

funds. Upon full and final payment hereunder of all amounts owing to such
removed Bank, such Bank shall make appropriate entries in its accounts
evidencing payment of all Loans hereunder and releasing the Borrower from all
obligations owing to the removed Bank in respect of the Loans hereunder and
surrender to the Administrative Agent for return to the Borrower any Notes of
the Borrower then held by it. Effective immediately upon such full and final
payment, such removed Bank will not be considered to be a "Bank" for purposes of
this Agreement except for the purposes of any provision hereof that by its terms
survives the termination of this Agreement and the payment of the amounts
payable hereunder. Effective immediately upon such removal, the Commitments of
such removed Bank shall immediately terminate. Such removal will not, however,
affect the Commitments of any other Bank hereunder.

     SECTION 10.16. Officer's Certificates. It is not intended that any
certificate of any officer of the Borrower delivered to the Administrative Agent
or any Bank pursuant to this Agreement shall give rise to any personal liability
on the part of such officer.

     SECTION 10.17. USA Patriot Act. Each Bank and the Administrative Agent (for
itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the "Patriot Act"), it is required to
obtain, verify and record information that identifies the Borrower, which
information includes the name and address of the Borrower and other information
that will allow such Bank or the Administrative Agent, as applicable, to
identify the Borrower in accordance with the Patriot Act. The Borrower shall,
and shall cause each of its Subsidiaries to, provide, to the extent commercially
reasonable, such information and take such actions as are reasonably requested
by each Bank and the Administrative Agent to maintain compliance with the
Patriot Act.
