                           (c) the Federal Funds Effective Rate in effect on

                  As used in this definition, (i) the term "Prime Rate" means
         the rate of interest per annum publicly announced from time to time by
         the Agent as its prime rate in effect at its principal office in New
         York City; (ii) the term "Base CD Rate" means the sum of (A) the
         product of (y) the Three-Month Secondary CD Rate and (z) a fraction,
         the numerator of which is one and the denominator of which is one minus
         the CD Reserve Percentage and (B) the Assessment Rate; (iii) the term
         "Three-Month Secondary CD Rate" means, for any day, the secondary
         market rate for three-month certificates of deposit reported as being
         in effect on such day (or, if such day is not a Business Day, the next
         preceding Business Day) by the Board through the public information
         telephone line of the Federal Reserve Bank of New York (which rate
         will, under the current practices of the Board, be published in Federal
         Reserve Statistical Release H.15(519) during the week following such
         day), or, if such rate is not so reported on such day or such next

         selected by it; (iv) the term "Assessment Rate" means for any day, the
         annual rate (rounded upwards to the nearest 1/100 of 1%) most recently

         that will be employed in determining amounts payable by the Agent to
         the Federal Deposit Insurance Corporation (or any successor) for
         insurance by such Corporation (or such successor) of time deposits made
         in Dollars at the Agent's domestic offices; and (v) the term "CD
         Reserve Percentage" means for any day, that percentage (expressed as a

         $1,000,000,000 in respect of new non-personal time deposits in Dollars
         in New York City having a maturity approximately equal to three months
         and in an amount of $100,000 or more. If for any reason the Agent shall

         manifest error) that it is unable to ascertain the Base CD Rate or the
         Federal Funds Effective Rate, or both, for any reason, including the
         inability or failure of the Agent to obtain sufficient quotations in
         accordance with the terms hereof, the ABR shall be determined without
         regard to clause (b) or (c) above or both, as appropriate, until the
         circumstances giving rise to such inability no longer exist. Any change
         in the ABR due to a change in the Prime Rate, the Three-Month Secondary
         CD Rate, the CD Reserve Percentage, the Assessment Rate or the Federal
         Funds Effective Rate shall be effective as of the effective day of such
         change in the Prime Rate, the Three-Month Secondary CD Rate, the CD
         Reserve Percentage, the Assessment Rate or the Federal Funds Effective
         Rate, respectively.

                                   ARTICLE II

                    AMOUNTS AND TERMS OF THE COMMITTED LOANS

         Section 2.01. The Committed Loans. Each Bank severally agrees, on the
terms and subject to the conditions hereinafter set forth, to make revolving
credit Loans (the "Committed Loans") to Borrower from time to time on any
Business Day during the period from the Effective Date until the Termination
Date in an aggregate principal amount not to exceed at any time outstanding such
Bank's Commitment; provided that no Committed Loan shall be made as a Committed
LIBOR Rate Loan after the day that is one month prior to the Termination Date;
and provided, further, that in no event shall the aggregate principal amount of
Committed Loans and CAF Loans outstanding at any time exceed the lesser of (i)
$400,000,000 and (ii) the aggregate amount of the Commitments at such time. Each
Committed Borrowing by Borrower shall be in an aggregate principal amount not
less than $10,000,000 (in the case of Committed 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 Loans of the same Type made on the same day by the
Banks ratably according to their respective Pro Rata Percentages. Within the
limits of the Commitments, Borrower may borrow, prepay pursuant to Section 5.05
and reborrow under this Section 2.01. The principal amount outstanding on the
Committed Loans shall mature and, together with accrued and unpaid interest
thereon, shall be due and payable on the Termination Date.

         Section 2.02. Making the Loans. (a) Each Committed Borrowing under
Section 2.01 shall be made on Borrower's oral or written notice given by
Borrower to the Agent (i) not later than 11:00 A.M. (New York City time) on the
third Business Day prior to the date of the proposed Committed Borrowing in the
case of a Committed LIBOR Rate Loan and (ii) not later than 11:00 A.M. (New York
City time) on the same Business Day of the proposed Committed Borrowing in the
case of an ABR Loan. With respect to any oral notice of borrowing given by
Borrower, Borrower shall promptly thereafter confirm such notice in writing.
Each written notice of borrowing and each confirmation of an oral notice of
borrowing shall be in substantially the form of Exhibit 2.02 hereto ("Notice of
Borrowing"). Each Notice of Borrowing shall be signed by Borrower and shall
specify therein the requested (i) date of such Committed Borrowing, (ii) Type of
Loans comprising such Committed Borrowing, (iii) aggregate amount of such
Committed Borrowing and (iv) with respect to any Committed LIBOR Rate Loan, the
Interest Period for each such Loan. The Agent shall promptly deliver a copy of
each Notice of Borrowing to each Bank, but in any event no later than 11:30 A.M.
(New York City time) on the relevant borrowing date. Each Bank shall, before
12:00 Noon (New York City time) on the date of such Committed Borrowing, make
available to the Agent at its address referred to in Section 11.02, in
immediately available funds, such Bank's applicable Pro Rata Percentage of such
Committed Borrowing. The Agent shall, no later than 1:00 P.M. (New York City
time), make such funds available to Borrower at Borrower's account as shall be
designated by Borrower to the Agent from time to time. Each Notice of Borrowing
shall be irrevocable and binding on Borrower.

                  (b) Unless the Agent shall have received notice from a Bank
prior to the date of any Committed Borrowing that such Bank will not make
available to the Agent such Bank's applicable Pro Rata Percentage of such
Committed Borrowing, the Agent may assume that such Bank has made such portion
available to the Agent on the date of such Committed Borrowing in accordance
with Section 2.02(a) and the Agent may, in reliance upon such assumption, make
available to Borrower on such date a corresponding amount. If such amount is
made available to the Agent on a date after such date of Committed Borrowing,
such Bank shall pay to the 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 Pro Rata Percentage of such Committed
Borrowing, times (iii) a fraction, the numerator of which is the number of days
that elapse from and including such date of Committed Borrowing to the date on
which such Bank's applicable Pro Rata Percentage of such Committed

<PAGE>
                                                                              17

Borrowing shall have become immediately available to the Agent and the
denominator of which is 360. A certificate of the Agent submitted to any Bank
with respect to any amounts owing under this Section 2.02(b) shall be conclusive
in the absence of manifest error. If such Bank shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Bank's Loan as
part of such Committed Borrowing for purposes of this Agreement. If such Bank's
applicable Pro Rata Percentage of such Committed Borrowing is not in fact made
available to the Agent by such Bank within three (3) Business Days of such date
of Committed Borrowing, the 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 Committed LIBOR
Rate Loans), on demand, from Borrower.

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

         Section 2.03. Minimum Tranches. All Borrowings, prepayments,
conversions and continuations of Committed 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 Committed LIBOR Rate Loans shall be
equal to $10,000,000 or an integral multiple of $1,000,000 in excess thereof.

                                  ARTICLE III

                       AMOUNTS AND TERMS OF THE CAF LOANS

         Section 3.01. The CAF Loans. From time to time on any Business Day
during the period from the Effective Date until the Termination Date, Borrower
may request CAF Loans from the Banks in amounts such that the aggregate
principal amount of Committed Loans and CAF Loans outstanding at any time shall
not exceed the aggregate amount of the Commitments at such time (the "CAF
Facility"). Under the terms and conditions set forth below, Borrower may borrow,
repay pursuant to Section 3.02(h) and reborrow under this Section 3.01.

         Section 3.02. Competitive Bid Procedure. (a) In order to request a CAF
Loan, Borrower shall deliver to the Agent a written notice in the form of
Exhibit 3.02-A, attached hereto (a "Competitive Bid Request"), to be received by
the Agent (i) in the case of each CAF LIBOR Rate Loan, not later than 3:00 P.M.
(New York City time), four (4) Business Days before the borrowing date specified
for such CAF LIBOR Rate Loan and (ii) in the case of each Fixed Rate Loan, not
later than 11:00 A.M. (New York City time), one (1) Business Day before the
borrowing date specified for such Fixed Rate Loan. Each Competitive Bid Request
shall in each case refer to this Agreement and specify (i) the date of Borrowing
of such CAF Loans (which shall be a Business Day), (ii) the aggregate principal
amount thereof, (iii) whether the CAF Loans then being requested are to be CAF
LIBOR Rate Loans or Fixed Rate Loans, (iv) the maturity date for each CAF Loan
requested to be made and (v) the interest payment dates for each CAF Loan
requested to be made. The Agent shall promptly notify each Bank by telex or
facsimile transmission of the contents of each Competitive Bid Request received
by it. Each Competitive Bid Request may solicit bids for CAF Loans in an
aggregate principal amount of $5,000,000 or an integral multiple of $1,000,000
in excess thereof and for not more than three alternative maturity dates for
such CAF Loans. The maturity date for each CAF Loan shall be not less than 15
days nor more than 180 days after the applicable date of CAF Borrowing (and in
any event shall not extend beyond the Termination Date).

<PAGE>
                                                                              18

                  (b) Each Bank may, in its sole discretion, irrevocably offer
to make one or more CAF Loans to Borrower responsive to each Competitive Bid
Request from Borrower. Any such irrevocable offer by a Bank must be received by
the Agent, in the form of Exhibit 3.02-B hereto (a "Competitive Bid"), (i) in
the case of each CAF LIBOR Rate Loan, not later than 10:30 A.M. (New York City
time), three (3) Business Days before the borrowing date specified for such CAF
LIBOR Rate Loan and (ii) in the case of each Fixed Rate Loan, not later than
9:30 A.M. (New York City time) on the borrowing date specified for such Fixed
Rate Loan. Competitive Bids that do not conform substantially to the format of
Exhibit 3.02-B may be rejected by the Agent after conferring with, and upon the
instruction of, Borrower, and the Agent shall notify the Bank of such rejection
as soon as practicable. Each Competitive Bid shall refer to this Agreement and
(i) specify the maximum principal amount of CAF Loans for each maturity date
(which shall be in an aggregate principal amount not less than $5,000,000 or an
integral multiple of $1,000,000 in excess thereof and which may equal, but not
exceed, the principal amount requested for such maturity date by Borrower) and
the aggregate maximum principal amount of CAF Loans for all maturity dates
(which amount, with respect to any Bank, may exceed such Bank's Commitment) that
the Bank is willing to make to Borrower; and (ii) specify the CAF Rate at which
the Bank is prepared to make each such CAF Loan. A Competitive Bid submitted by
a Bank pursuant to this Section 3.02(b) shall be irrevocable.

                  (c) The Agent shall (i) in the case of each CAF LIBOR Rate
Loan, not later than 11:00 A.M. (New York City time) three (3) Business Days
before the borrowing date specified for such CAF LIBOR Rate Loan and (ii) in the
case of each Fixed Rate Loan, not later than 10:00 A.M. (New York City time) on
the borrowing date specified for such Fixed Rate Loan, notify Borrower in
writing of all the Competitive Bids made (arranging each such bid in ascending
interest rate order), and the CAF Rate or Rates and the maximum principal amount
of each CAF Loan in respect of which Competitive Bid was made, and the identity
of the Bank that made each bid. The Agent shall send a copy of all Competitive
Bids to Borrower for its records as soon as practicable after completion of the
bidding process set forth in this Section 3.02.

                  (d) Borrower may in its sole and absolute discretion, subject
only to the provisions of this Section 3.02(d), accept or reject any Competitive
Bid referred to in Section 3.02(c); provided, however, that the aggregate amount
of Borrower's Competitive Bids so accepted by Borrower may not exceed the lesser
of (i) the principal amount of the CAF Borrowing requested by Borrower or (ii)
the amount of the Commitments less the aggregate principal amount of Committed
Loans and CAF Loans made to Borrower and outstanding at such time after giving
effect to the application of the proceeds of such CAF Borrowing on the borrowing
date therefor. Borrower shall notify the Agent in writing whether and to what
extent it has decided to accept or reject any or all of the bids referred to in
Section 3.02(c) by delivering to the Agent a written notice in the form of
Exhibit 3.02-C hereto (a "Competitive Bid Confirmation"), (i) in the case of
each CAF LIBOR Rate Loan, not later than 1:00 P.M. (New York City time), three
(3) Business Days before the borrowing date specified for such CAF LIBOR Rate
Loan and (ii) in the case of each Fixed Rate Loan, not later than 11:00 A.M.
(New York City time) on the borrowing date specified for such Fixed Rate Loan,
which Competitive Bid Confirmation shall specify the principal amount of CAF
Loans for each relevant maturity date to be made by each such bidding Bank
(which amount for each such maturity date shall be equal to or less than the
maximum amount for such maturity date specified in the Competitive Bid of such
Bank, and for all maturity dates included in such Competitive Bid shall be equal
to or less than the aggregate maximum amount specified in such Competitive Bid
for all such maturity dates); provided, however, that (A) the failure by
Borrower to so deliver a Competitive Bid Confirmation shall be deemed to be a
rejection of all the bids referred to in Section 3.02(c); (B) Borrower shall not
accept a bid made at a particular CAF Rate for a particular maturity if Borrower
has decided to reject a bid made at a lower CAF Rate for such maturity; (C) if
Borrower shall accept bids made at a particular CAF Rate for a particular
maturity but shall be restricted by other conditions hereof from borrowing the
maximum principal amount of CAF Loans in respect of
<PAGE>
                                                                              19

which bids at such CAF Rate have been made, then Borrower shall accept a pro
rata portion of each bid made at such CAF Rate based as nearly as possible on
the respective maximum principal amounts of CAF Loans offered to be made by the
relevant Banks pursuant to such bids; and (D) no bid shall be accepted for a CAF
Loan by any Bank unless such CAF Loan is in an aggregate principal amount not
less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof.
Notwithstanding the foregoing, if it is necessary for Borrower to accept a pro
rata allocation of the bids made in response to a Competitive Bid Request
(whether pursuant to the events specified in clause (C) above or otherwise) and
the available principal amount of CAF Loans to be allocated among the Banks is
not sufficient to enable CAF Loans to be allocated to each Bank in an aggregate
principal amount not less than $5,000,000 or in integral multiples of $1,000,000
in excess thereof, then Borrower shall, subject to clause (D) above, select the
Banks to be allocated such CAF Loans and shall round allocations up or down to
the next higher or lower multiple of $1,000,000 as it shall deem appropriate;
provided that the allocations among the Banks to be allocated such CAF Loans
shall be made pro rata based as nearly as possible on the respective maximum
principal amounts of CAF Loans offered to be made by such Banks. The Competitive
Bid Confirmation given by Borrower pursuant to this Section 3.02(d) shall be
irrevocable.

                  (e) Upon receipt from the Agent of the LIBOR Rate applicable
to any CAF LIBOR Rate Loan to be made by any Bank pursuant to a Competitive Bid
that has been accepted by Borrower pursuant to Section 3.02, the Agent shall
notify such Bank of the applicable LIBOR Rate.

                  (f) If the Agent shall at any time elect to submit a
Competitive Bid in its capacity as a Bank, it shall submit such bid directly to
Borrower by (i) in the case of a CAF LIBOR Rate Loan, not later than 10:15 A.M.
(New York City time), and (ii) in the case of a Fixed Rate Loan, not later than
9:15 A.M. (New York City time), in each case, on the Business Day on which the
other Banks are required to submit their bids to the Agent pursuant to Section
3.02(b) above.

                  (g) If Borrower accepts pursuant to Section 3.02(d) one or
more of the offers made by any Bank or Banks, the Agent shall promptly notify
each Bank that has made such an offer of the aggregate amount of such CAF Loans
to be made on such borrowing date for each maturity date and of the acceptance
or rejection of any offers to make such CAF Loans made by such Bank. Each Bank
that is to make a CAF Loan shall, before 12:00 Noon (New York City time) on the
borrowing date specified in the Competitive Bid Request applicable thereto, make
available to the Agent at its office set forth in Section 11.02 the amount of
CAF Loans to be made by such Bank, in immediately available funds. The Agent
shall, no later than 1:00 P.M. (New York City time) on such borrowing date, make
such funds available to Borrower at Borrower's account as shall be designated by
it to the Agent from time to time. As soon as practicable after each borrowing
date, the Agent shall notify each Bank of the aggregate amount of CAF Loans
advanced on such borrowing date and the respective maturity dates thereof.

                  (h) Borrower shall repay to the Agent for the account of each
Bank that has made a CAF Loan (or the CAF Loan Assignee in respect thereof, as
the case may be) on the maturity date of each CAF Loan (such maturity date being
that specified by Borrower for repayment of such CAF Loan in the related
Competitive Bid Request) the then unpaid principal amount of such CAF Loan.
Borrower shall not have the right to prepay any principal amount of any CAF
Loan.

                  (i) All notices required by this Section 3.02 shall be made in
accordance with Section 11.02 hereof; provided, however, that each request or
notice required to be made under Section 3.02(a) or 3.02(d) by Borrower may be
made by the giving of telephone notice to the Agent that is promptly confirmed
by delivery of a notice in writing (in substantially the form of Exhibit 3.02-A
or Exhibit 3.02-C, as the case may be) to the Agent.

                        PROVISIONS RELATING TO ALL LOANS

         Section 4.01. The Loans. (a) Each Bank shall maintain in accordance
with its usual practice an account or accounts evidencing indebtedness of
Borrower to such bank resulting from each Committed Loan and each CAF Loan of
such Bank from time to time, including the amounts of principal and interest
payable and paid to such Bank from time to time under this Agreement.

                  (b) The Agent shall maintain the Register pursuant to
subsection 11.06(e) and a subaccount therein for each Bank, in which shall be
recorded (i) the amount of each Committed Loan and CAF Loan made by the Banks
through the 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 Borrower to each Bank hereunder and (iii) both
the amount of any sum received by the Agent hereunder from Borrower and each
Bank's share thereof.

                  (c) The entries made in the Register and the accounts of each
Bank maintained pursuant to subsection 4.01(a) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of Borrower therein recorded; provided, however, that the failure of
any Bank or the Agent to maintain the Register or any such account, or any error
therein, shall not in any manner affect the obligation of Borrower to repay
(with applicable interest) the Loans actually made to Borrower by such Bank in
accordance with the terms of this Agreement.

         Section 4.02. Fees. (a) Borrower agrees to pay to the Agent for the
account of each Bank a facility fee (the "Facility Fee") on the average daily
amount of such Bank's Commitment, from the date hereof until the Termination
Date, payable quarterly in arrears beginning on September 30, 2001 and
continuing thereafter on the last day of each March, June, September and

 BB+/BB+/Ba1 or lower or unrated                                  0.250%
</TABLE>

                  (b) The Facility Fees payable under Section 4.02(a) and the
fees payable under Section 4.02(e) shall be calculated by the 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.

                  (c) The Designated Ratings set forth in Section 4.02(a)
correspond to the Designated Ratings assigned by Standard & Poor's Ratings
Group, Fitch, Inc. and Moody's Investors Service, Inc., respectively.

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

                  (e) Borrower agrees to pay to the Agent for the account of
each Bank a usage fee at a rate of 0.125% per annum on the aggregate outstanding
principal amount of all Loans (other than CAF Loans) owed to such Bank at all
times during which the aggregate outstanding principal amount of all Loans
(other than CAF Loans) exceeds 33 1/3% of the Commitments of the Banks, payable
quarterly in arrears on the last day of each March, June, September and December
during the term of this Agreement, commencing September 30, 2001, and on the
Termination Date.

         Section 4.03. Termination or Reduction of the Commitments. Borrower
shall have the right, upon at least three (3) Business Days' irrevocable notice
to the Agent, to terminate in whole or permanently reduce ratably in part the
unused portions of its Commitments, provided that (a) 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 (b) no such termination or reduction shall
be permitted if, after giving effect thereto and to any prepayments made under
Section 5.05 hereof by Borrower on the effective date thereof, the aggregate
principal amount of Loans made to Borrower and then outstanding would exceed the
Commitments then in effect.

         Section 4.04. Interest. 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 and (ii) the Highest
Lawful Rate, payable quarterly in arrears on the last day of each March, June,
September and December, commencing on September 30, 2001 and on the Termination
Date.

                  (b) LIBOR Rate Loans. Each LIBOR Rate Loan shall bear interest
at a rate per annum equal at all times to (i) in the case of each Committed
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 or nine 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 Termination Date and (ii) in the case of
each CAF LIBOR Rate Loan, the lesser of (A) the sum of the LIBOR Rate applicable
to such Loan plus or minus, as the case may be, the CAF Margin specified by a
Bank with respect to such Loan in its Competitive Bid submitted pursuant to
Section 3.02(b) and (B) the Highest Lawful Rate, payable on the date or dates
specified in the relevant Competitive Bid Request.

                  (c) Fixed Rate Loans. Each Fixed Rate Loan shall bear interest
at a rate per annum equal at all times to the lesser of (i) the fixed rate of
interest offered by the Bank making such Loan and accepted by Borrower pursuant
to Section 3.02 and (ii) the Highest Lawful Rate, payable on the date or dates
specified in the relevant Competitive Bid Request.

                  (d) Interest payable under Sections 4.04(a) and 4.04(e) (to
the extent that the calculation of the Default Rate thereunder is based on the
Alternate Base Rate) shall be calculated by the 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. Interest payable under Sections 4.04(b), (c) and (e) (to the extent
that the calculation of the Default Rate is based on either the LIBOR Rate or
the rate set forth in Section 4.04(c)) shall be calculated by the 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.

                  (e) Notwithstanding the foregoing, if all or a portion of (i)
the principal amount of any Loan, (ii) any interest payable thereon, or (iii)
any Facility 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).

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

                  (g) If any Reference Bank shall for any reason no longer have
a Commitment or any Loans, such Reference Bank shall thereupon cease to be a
Reference Bank, and if, as a result, there shall only be one Reference Bank
remaining, the Agent (after consultation with Borrower and the Banks) shall, by
notice to Borrower and the Banks, designate another Bank as a Reference Bank so
that there shall at all times be at least two Reference Banks.

                  (h) Each Reference Bank shall use its best efforts to furnish
quotations of rates to the Agent as contemplated hereby. If any of the Reference
Banks shall be unable or shall otherwise fail to supply such rates to the Agent
upon its request, the rate of interest shall, subject to the provisions of
Section 4.06(b), be determined on the basis of the quotations of the remaining
Reference Banks or Reference Bank.

                  Section 4.05. Reserve Requirements. (a) Borrower agrees to pay
to each Bank that requests compensation under this Section 4.05 in accordance
with the provisions set forth in Section 5.07(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 Borrower pursuant to the provisions set forth in Section
5.07(b)) representing such Bank's calculation or, if an accurate calculation is
impracticable, reasonable estimate (using such method of allocation to such
Loans of Borrower as such Bank shall determine in accordance with Section
5.07(a)) of the actual costs, if any, incurred by such Bank during the relevant
Interest Period or during the period a CAF LIBOR Rate Loan made by such Bank was
outstanding, as the case may be, as a result of the applicability of the
foregoing reserves to such Committed LIBOR Rate Loans or CAF LIBOR Rate Loans,
which amount in any event shall not exceed the product of the following for each
day of such Interest Period or each day during the period such CAF LIBOR Rate
Loan was outstanding, as the case may be:

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

                  (ii) the difference between (A) a fraction, the numerator of
         which is the LIBOR Rate (expressed as a decimal) applicable to such
         Committed LIBOR Rate Loan or CAF LIBOR Rate Loan, as the case may be
         (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 4.05 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

         Section 4.06. Interest Rate Determination and Protection. (a) The rate
of interest for each Committed LIBOR Rate Loan shall be determined by the Agent
two (2) Business Days before the first day of each Interest Period applicable to
such Loan. The Agent shall give prompt notice to Borrower and the Banks of the
applicable interest rate determined by the Agent for purposes of Sections
4.04(a) and (b) hereof.

                  (b) If, with respect to any Committed LIBOR Rate Loans, prior
to the first day of an Interest Period (i) the Agent shall have determined
(which determination shall be conclusive and binding upon 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 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
Committed LIBOR Rate Loans during such Interest Period, the Agent shall give
telecopy or telephonic notice thereof to Borrower and the Banks as soon as
practicable thereafter. If such notice is given, (A) any Committed LIBOR Rate
Loans requested to be made on the first day of such Interest Period shall be
made as ABR Loans, (B) any Committed Loans that were to have been converted on
the first day of such Interest Period to Committed LIBOR Rate Loans shall be
continued as ABR Loans and (C) any outstanding Committed 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 Agent, no further Committed LIBOR Rate Loans
shall be made or continued as such, nor shall Borrower have the right to convert
Committed Loans to Committed LIBOR Rate Loans.

         Section 4.07. Voluntary Interest Conversion or Continuation of
Committed Loans. (a) Borrower may on any Business Day, upon its irrevocable oral
or written notice of interest conversion/continuation given by it to the 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
Committed LIBOR Rate Loan, (i) convert Committed Loans of one Type into
Committed Loans of another Type; (ii) convert Committed LIBOR Rate Loans for a
specified Interest Period into Committed LIBOR Rate Loans for a different
Interest Period; or (iii) continue Committed LIBOR Rate Loans for a specified
Interest Period as Committed LIBOR Rate Loans for the same Interest Period;
provided, however, that (A) any conversion of any Committed LIBOR Rate Loans
into Committed LIBOR Rate Loans for a different Interest Period, or into ABR
Loans, or any continuation of Committed LIBOR Rate Loans for the same Interest
Period shall be made on, and only on, the last day of an Interest Period for
such Committed LIBOR Rate Loans; (B) no Committed Loan may be converted into or
continued as a Committed LIBOR Rate Loan by Borrower so long as an Event of
Default has occurred and is continuing; (C) no Committed Loan may be converted
into or continued as a Committed LIBOR Rate Loan after the date that is one
month prior to the Termination Date, and (D) no Committed Loan may be converted
into or continued as a Committed LIBOR Rate Loan if, after giving effect
thereto, Section 2.03 would be contravened. With respect to any oral notice of
interest conversion/continuation given by Borrower under this Section 4.07(a),
Borrower shall promptly thereafter confirm such notice in writing. Each written
notice of interest conversion/continuation given by Borrower under this Section
4.07(a) and each confirmation of an oral notice of interest conversion/
continuation given by Borrower under this Section 4.07(a) shall be in
substantially the form of Exhibit 4.07 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 Committed Loans to be converted or continued; and (z) if
such interest conversion or continuation is into Committed LIBOR Rate Loans, the
duration of the Interest Period for each such Committed LIBOR Rate Loan. The
Agent shall

                                                                              24

promptly deliver a copy of each Notice of Interest Conversion/Continuation to
each Bank. Each Notice of Interest Conversion/Continuation shall be irrevocable
and binding on Borrower.

                  (b) If Borrower shall fail to deliver to the Agent a Notice of
Interest Conversion/Continuation in accordance with Section 4.07(a) hereof, or
to select the duration of any Interest Period for the principal amount
outstanding under any Committed 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 4.07(a), the Agent will
forthwith so notify Borrower and the Banks (provided that the failure to give
such notice shall not affect the conversion referred to below) and such
Committed Loans will automatically, on the last day of the then existing
Interest Period therefor, convert into ABR Loans.

         Section 4.08. Funding Losses Relating to LIBOR Rate Loans. (a) 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 Borrower in
payment when due of the principal amount of or interest on any LIBOR Rate Loan,
(ii) default by Borrower in making a borrowing of, conversion into or
continuation of LIBOR Rate Loans after Borrower has given a notice requesting
the same in accordance with the provisions of this Agreement, (iii) default by
Borrower in making any prepayment after 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 Committed LIBOR Rate Loans
into ABR Loans, on a day that is not the last day of an Interest Period with
respect thereto (excluding any prepayment made pursuant to Section 4.09),
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 4.08(a) shall be made pursuant to the
method described in Section 5.07(a), but in no event shall such amounts 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 (A) with respect to any Committed LIBOR Rate
Loan, the relevant Interest Period and (B) with respect to any CAF LIBOR Rate
Loan, the maturity set forth in the Competitive Bid applicable thereto;
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 4.08(a).

                  (b) The agreements in this Section 4.08 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

         Section 4.09. Change in Legality. (a) Notwithstanding any other
provision of this Agreement, if any Bank shall notify the Agent that the
introduction of or any change in or in the interpretation or application of any
law or regulation makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for any Bank or its LIBOR 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 Committed Loans into, or to continue Committed LIBOR Rate Loans as,
LIBOR Rate Loans shall be suspended until the Agent shall notify Borrower that
the circumstances causing such suspension no longer exist; (ii) Borrower shall,
at its option, either prepay in full all Committed 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 (iii) Borrower shall, with respect
to each CAF LIBOR Rate Loan of such Bank, take such action as such Bank shall
reasonably request. Each Bank agrees that it will use reasonable efforts to
designate a different Applicable Lending Office for the LIBOR Rate Loans due to
it affected by this
<PAGE>
                                                                              25

Section 4.09, if such designation will avoid the illegality described in this
Section 4.09 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 4.09, a notice to Borrower
(with a copy to the Agent) by any Bank pursuant to paragraph (a) above shall be
effective on the date of receipt thereof by Borrower.

         Section 4.10. Extension of Commitments. (a) Borrower may, by written
request to the Agent given not more than 65 days prior to the Termination Date
then in effect with respect to the Commitments of the Banks (the "Applicable
Termination Date"), and in a form reasonably acceptable to the Agent (an
"Extension Request"), request that the Applicable Termination Date be extended
to the date that is 364 days following such Applicable Termination Date, which
request shall identify (i) the most recent audited financial statements of
Borrower that have been delivered to the Banks pursuant to Section 8.01(a)(i)
and (ii) the most recent unaudited financial statements of Borrower, if any,
that have been delivered to the Banks pursuant to Section 8.01(a)(ii) relating
to periods subsequent to the period covered by the audited financial statements
referred to in clause (i) above (such audited financial statements and any such
unaudited financial statements being collectively referred to as the "Extension
Financial Statements"). The Agent shall, within five days of receipt of the
Extension Request, request each Bank to indicate whether or not it consents to
such extension (which consent may be granted or withheld by each Bank in its
sole discretion). Not more than 60 days and not less than 45 days before the
Applicable Termination Date, each Bank will notify Borrower in writing (with a
copy thereof to the Agent) whether or not it consents to such Extension Request;
provided that any Bank that fails to so advise Borrower within such time period
(the "Extension Consideration Period") shall be deemed to have denied such
Extension Request. Subject to the provisions of Sections 4.10(b) and 4.10(c)
below, the extension of the Applicable Termination Date then in effect
contemplated by such Extension Request shall become effective as of such
Applicable Termination Date only upon satisfaction of the following conditions
as of such date: (A) no Default or Event of Default shall have occurred and be
continuing; (B) Borrower shall be in compliance with and shall have performed
all agreements and covenants made by it under this Agreement; and (C) the
representations and warranties made by Borrower in Section 7.01 hereof (except
for those representations and warranties or parts thereof that, by their terms,
expressly relate solely to a specific date, in which case such representations
and warranties shall be true and correct in all material respects as of such
specific date) shall be true and correct in all material respects on and as of
said date with the same force and effect as if made on or as of such date;
provided that (y) the representations and warranties set forth in Section
7.01(j) will be made with respect to the latest date covered by the Extension
Financial Statements and (z) the representations and warranties set forth in
Section 7.01(m) will be made with respect to the Extension Financial Statements.
Each such Extension Request by Borrower under this Section 4.10 shall constitute
a certification by Borrower to the effect set forth in clauses (A), (B) and (C)
of the preceding sentence (both as of the date of such notice and, unless
Borrower otherwise notifies the Agent, as of such Applicable Termination Date).
Upon the effectiveness of any extension of the Applicable Termination Date
pursuant to any Extension Request under this Section 4.10, the representations
and warranties set forth in Section 7.01(j) shall, as of the effective date of
such extension, be deemed for all purposes, including, without limitation,
Section 6.02(i), to be made with respect to of the audited financial statements
included in the Extension Financial Statements identified in such Extension
Request.

                  (b) In the event that Banks representing at least 51% of the
Commitments at the time Borrower delivers the Extension Request (the "Continuing
Banks") advise the Agent in writing during the Extension Consideration Period
(the last day of such Period being referred to herein as the "Consent Date") of
their consent to a requested extension, which consent shall be irrevocable, the
applicable Termination Date for the Loans held or thereafter made by the
Continuing Banks shall, subject to the
<PAGE>
                                                                              26

provisions of Section 4.10(c) and without derogation of the Banks' rights to
demand payment therefor, be automatically extended for a 364-day period from the
Applicable Termination Date then in effect; provided, however, that the
Applicable Termination Date for the Loans of those Banks that shall not have
consented to such extension ("Non-Consenting Banks") shall not be affected. Any
Bank that does not advise the Agent of its consent as aforesaid will, as of 5:00
P.M. (New York City time), on the Consent Date, without any further action on
its part, be deemed a Non-Consenting Bank. In the event of the extension
(subject to the provisions of Section 4.10(c)) of the Applicable Termination
Date pursuant to this Section 4.10(b), the Agent shall promptly notify Borrower
and all of the Banks. Any Non-Consenting Bank may, by written notice to the
Agent and Borrower given within 15 days following receipt by such Bank of any
such notice from the Agent, advise the Agent and Borrower of its election to
become a Continuing Bank. Upon receipt by the Agent of any such notice from a
Non-Consenting Bank, such Non-Consenting Bank, subject to the provisions of
Section 4.10(c), shall thereupon cease to be a Non-Consenting Bank and, in lieu
thereof, shall irrevocably become a Continuing Bank and the Applicable
Termination Date then in effect for the Loans held by such Bank shall be
automatically extended as provided above in this Section 4.10. The Agent shall
promptly notify Borrower and the Banks in the event any Non-Consenting Bank
becomes a Continuing Bank as hereinabove provided.

                  (c) In the event of an extension of the Applicable Termination
Date pursuant to Section 4.10(b), the Continuing Banks, or any of them, shall
have the right (but not the obligation) to assume all or any part of the
Non-Consenting Banks' Commitments by giving written notice to Borrower and the
Agent of their election to do so on or before the 30th day next preceding the
Applicable Termination Date in effect at the time the Extension Request was
given, which notice shall be irrevocable and shall constitute an undertaking to
purchase (without recourse), pursuant to a Committed Loan Assignment and
Acceptance, from the Non-Consenting Banks, at the close of business on the
Applicable Termination Date, all Loans outstanding on the Applicable Termination
Date that correspond to the portion of the Commitments to be assumed at a price
equal to the unpaid principal amount of such Loans plus all accrued and unpaid
interest and fees thereon. Such Commitments, or portion thereof, to be assumed
by Continuing Banks shall be allocated among those Continuing Banks who have so
elected to assume the same pro rata in accordance with the respective
Commitments of such Continuing Banks as of the date of the Extension Request or
on such other basis as such Continuing Banks shall mutually agree; provided,
however, that immediately following such allocation the Commitment of any
Continuing Bank shall not constitute more than 16.6% of the Commitments of all
the Continuing Banks. In the event that the Continuing Banks shall not elect as
hereinabove provided to assume all of the Non-Consenting Banks' Commitments on
or before the 30th day next preceding the Applicable Termination Date, then
Borrower may thereafter, with the consent of the Agent (which consent shall not
be unreasonably withheld), arrange for the assumption by one or more new lending
institutions, effective as of the close of business on the Applicable
Termination Date, of that part of the Non-Consenting Banks' Commitments not to
be assumed by the Continuing Banks; provided, however, that each such new
lending institution (i) shall not have a Commitment that shall constitute more
than 16.6% of the Commitments of all the Continuing Banks and any such new
lending institutions, (ii) shall, pursuant to a Committed Loan Assignment and
Acceptance, purchase (without recourse) from the Non-Consenting Banks, at the
close of business on the Applicable Termination Date, all Loans outstanding on
the Applicable Termination Date that correspond to the portion of the
Commitments to be so assumed at a price equal to the unpaid principal amount of
such Loans plus all accrued and unpaid interest and fees thereon, (iii) shall
assume, pursuant to a Committed Loan Assignment and Acceptance, its share of the
obligations of the Non-Consenting Banks hereunder, including, but not limited
to, its share of the Commitments of such Non-Consenting Banks, (iv) shall agree,
pursuant to a Committed Loan Assignment and Acceptance, to be bound as a Bank by
the terms of this Agreement and (v) shall execute and deliver to the Agent such
other documents as the Agent may reasonably require to evidence the succession
of interest; and provided further, that upon satisfaction of the foregoing and
effective at the close of business on the Applicable Termination Date, (i) the
Non-Consenting Banks shall sell (pro rata and without recourse) their respective
Loans that each new lending
<PAGE>
                                                                              27

institution has agreed to purchase hereunder, (ii) each Non-Consenting Bank and
the Agent shall make entries in the accounts of each such Non-Consenting Bank
and the Register, respectively, evidencing the purchase of the Loans by each new
lending institution, (iii) each such new lending institution shall become a Bank
for all purposes hereof, (iv) each Non-Consenting Bank shall cease to be a Bank
hereunder and shall be released from all obligations hereunder (other than those
arising prior to the close of business on the Applicable Termination Date), (v)
Borrower shall be released from any and all obligations owing hereunder to such
Non-Consenting Bank (other than those arising prior to the close of business on
the Applicable Termination Date) and (vi) in the event that any Notes have been
issued to such Non-Consenting Bank, such Notes shall be marked "cancelled" and
surrendered by the Non-Consenting Bank to the Agent for return to Borrower. If
and to the extent that, on the third full Business Day prior to the Applicable
Termination Date, the Continuing Banks shall not have elected to assume all of
the Non-Consenting Banks' Commitments and Borrower shall not have been able to
arrange for an assumption of all of the Non-Consenting Banks' Commitments as
contemplated by the foregoing provisions of this Section 4.10(c), then Borrower
shall pay the remaining balance of the principal of, interest on, and fees in
respect of, the Loans made by each Non-Consenting Bank, as well as any other
amounts payable to such Non-Consenting Bank pursuant to this Agreement, prior to
the close of business on the Applicable Termination Date, in which event the
Commitments of the Non-Consenting Banks shall terminate and the aggregate
Commitments hereunder shall be accordingly reduced.

                                   ARTICLE V

                INCREASED COSTS, TAXES, PAYMENTS AND PREPAYMENTS

         Section 5.01. 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 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 subject any Bank to any tax of any kind whatsoever
         with respect to this Agreement, any Note or any LIBOR Rate Loan made by
         it, or change the basis of taxation of payments to such Bank in respect
         thereof (except for (A) Taxes covered by Section 5.03, (B) net income
         taxes and franchise taxes imposed on such Bank as a result of a present
         or former connection between the jurisdiction of the government or
         taxing authority imposing such tax and such Bank other than a
         connection arising solely from such Bank having executed, delivered or
         performed its obligations or received a payment under, or enforced,
         this Agreement or the Loans and (C) changes in the rate of tax on the
         overall net income of such Bank);

                  (ii) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of,
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of such Bank that is not otherwise
         included in the determination of the LIBOR Rate hereunder (except for
         amounts covered by Section 4.05 or any other Section hereof); or

                  (iii) 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, Borrower shall
promptly pay such Bank, upon its demand in the manner set forth in Section
5.07(b), any additional amounts, computed by such Bank in accordance with
Section 5.07(a), necessary to compensate such Bank for such actual increased
cost or reduced amount receivable that is attributable to Loans or Commitments
<PAGE>
                                                                              28

(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
5.01(a) from Borrower, it shall promptly notify Borrower, through the Agent, of
the event by reason of which it has become so entitled in the manner set forth
in Section 5.07(b).

                  (b) If any Bank determines in good faith that the introduction
of or any change in or in the interpretation or application 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,
Borrower shall pay to the Agent for the account of such Bank, from time to time
as specified by such Bank in the manner set forth in Section 5.07(b), additional
amounts, computed by such Bank in accordance with Section 5.07(a), sufficient to
compensate 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 5.01 shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

         Section 5.02. Payments and Computations. (a) Borrower shall make each
payment (including each prepayment) hereunder and under the Loans, 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 Agent at its address referred to in Section 11.02 in
immediately available funds. The Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal or interest or
Facility Fees (to the extent received by the Agent) ratably to the Banks for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Bank (to the extent received
by the Agent) to such Bank for the account of its Applicable Lending Office, in
each case to be applied in accordance with the terms of this Agreement.

                  (b) Whenever any payment hereunder or under the Loans 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.

                  (c) Unless the Agent shall have received notice from Borrower
prior to the date on which any payment is due to the Banks hereunder that
Borrower will not make such payment in full, the Agent may assume that Borrower
has made such payment in full to the Agent on such date and the 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
Borrower shall not have so made such payment in full to the Agent, each Bank
shall pay to the 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 Pro Rata 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 applicable Pro Rata Percentage of such payment shall have become
immediately available to the Agent and the denominator of which is 360.

         Section 5.03. Taxes. (a) Except with respect to withholdings of United
States taxes as provided in Section 5.03(d), any and all payments by Borrower
hereunder or under the Loans shall be made, in accordance with Section 5.02,
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 Agent, net income taxes and franchise taxes imposed on it
as a result of a present or former connection between the jurisdiction of the
government or taxing authority imposing such tax and the Agent or such Bank
other than a connection arising solely from the Agent or such Bank having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or the Loans (all such non-excluded taxes, levies,
imposts, deductions, charges, withholdings and liabilities being hereinafter
referred to as "Taxes"). Except with respect to withholdings of United States
taxes as provided in Section 5.03(d), if Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder or under any
Loans to any Bank or the 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 5.03) such Bank or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made; (ii) Borrower shall make such
deductions; and (iii) Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
law. If requested by any Bank, Borrower shall confirm that all applicable Taxes,
if any, imposed on it by virtue of the transactions under this Agreement have
been properly and legally paid by it to the appropriate taxing authorities by
sending 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 Borrower confirming that such
Taxes have been paid, together with evidence of such payment.

                  (b) In addition, Borrower agrees to pay, in the manner set
forth in Section 5.07(b), 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 the Loans or from the execution, delivery or
registration of, or otherwise with respect to, this Agreement or the Loans and
for which such Bank or the Agent (as the case may be) has not been otherwise
reimbursed by Borrower under this Agreement (hereinafter referred to as "Other
Taxes").

                  (c) Borrower will indemnify each Bank and the 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
5.03) paid by such Bank or the 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, any incremental taxes,
interest or penalties that may become payable by the Agent or any Bank as a
result of any failure by 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 and each CAF Loan Assignee 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 Agent two duly completed
copies of United States Internal Revenue Service Form W-8BEN or W-8ECI or
successor applicable forms, as the case may be. Each such Bank and each such CAF
Loan Assignee also agrees to deliver to the Borrower and the Agent two further
copies of the said Form W-8BEN or W-8ECI, 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 previously delivered by it to the Borrower, and
such extensions or renewals thereof as may reasonably be requested by the
Borrower or the Agent, 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
<PAGE>
                                                                              30

Bank or such CAF Loan Assignee from duly completing and delivering any such form
with respect to it and such Bank or such CAF Loan Assignee so advises the
Borrower and the Agent. Each such Bank and each such CAF Loan Assignee shall
certify in the case of a Form W-8BEN or W-8ECI that it is entitled to receive
payments under this Agreement without deduction or withholding of any United
States federal income taxes. In the event that any such Bank or CAF Loan
Assignee fails to deliver any forms required under this Section 5.03(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) The agreements in this Section 5.03 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder. Nothing contained in this Section 5.03 shall require Borrower
to pay any amount to any Bank or the Agent in addition to that for which it has
already reimbursed any Bank or the Agent under any other provision of this
Agreement.

         Section 5.04. Sharing of Payments, Etc. If any Bank (a "benefitted
Bank") shall at any time receive any payment (other than pursuant to Section
4.05, 4.08, 5.01 or 5.03) of all or part of its Committed Loans, 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 9.01(g) or 9.01(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 Committed Loans, 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 Committed Loans 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. Borrower agrees that any Bank
so purchasing a participation from another Bank pursuant to this Section 5.04
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 Borrower in the amount of such
participation.

         Section 5.05. Voluntary Prepayments. Subject to Section 4.08, Borrower
may, upon notice delivered to the Agent not later than 11:00 A.M. (New York City
time) one (1) Business Day prior to the date of prepayment stating the aggregate
principal amount of the prepayment and the Committed Loans to be prepaid, prepay
the outstanding principal amounts of such Committed Loans comprising part of the
same Committed 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 all such prepayments shall be made without premium or
penalty thereon; and provided further that losses incurred by any Bank under
Section 4.08 shall be payable with respect to each such prepayment in the manner
set forth in Section 4.08. Such notice 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 with respect to any Tranche of Committed
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 or
(b) the aggregate principal amount of such Tranche of Committed LIBOR Rate Loans
then outstanding, as the case may be; provided, that, no partial prepayment of
any Tranche of Committed LIBOR Rate Loans may be made if, after giving effect
thereto, Section 2.03 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 5.06. Mitigation of Losses and Costs. Any Bank claiming
reimbursement from Borrower under Sections 4.05, 4.08, 5.01 and 5.03 hereof
shall use reasonable efforts (including, without
<PAGE>
                                                                              31

limitation, if requested by Borrower, reasonable efforts to designate a
different Applicable 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 (a) any economic
disadvantage for which such Bank does not receive full indemnity from Borrower
under this Agreement or (b) any legal or regulatory disadvantage.

         Section 5.07. Determination and Notice of Additional Costs and Other
Amounts. (a) In determining the amount of any claim for reimbursement or
compensation under Sections 4.05, 4.08 and 5.01, 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 5.03, the Agent, as the case may be, will (i) use best
efforts to notify Borrower through the 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 Borrower through the Agent (in the case of each Bank)
promptly after such Bank or the 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 5.07(b), a "Triggering Event") will entitle such
Bank or the Agent, as the case may be, to compensation pursuant to Section 4.05,
4.08, 5.01 or 5.03, as the case may be. Each such notification of a Triggering
Event shall be accompanied by a certificate of such Bank or the Agent, as the
case may be, setting forth in reasonable detail such amount or amounts as shall
be necessary to compensate such Bank or the Agent, as the case may be, as
specified in Section 4.05, 4.08, 5.01 or 5.03, as the case may be, which
certificate shall be conclusive absent manifest error. Borrower shall pay to the
Agent for the account of such Bank or to the Agent for its own account, as the
case may be, the amount shown as due on any such certificate within ten (10)
Business Days after its receipt of the same.

                                   ARTICLE VI

         thereunder.

Borrowing, the following statements shall be true and correct (and each of the
giving of any applicable Notice of Borrowing or Competitive Bid Confirmation, as

                                  ARTICLE VII

good standing in each other jurisdiction in which the conduct of its business or

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

requisite power to execute, deliver and perform and comply with its obligations
under this Agreement, any Notes and the

Borrower contemplated by this Agreement, the execution and delivery by Borrower

Borrower or any Subsidiary of Borrower is a party or by which Borrower or any
Subsidiary of 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 on
Borrower); or (iii) result in, or require, the creation or imposition of any
material Lien upon any of the Properties of Borrower or any Significant
Subsidiary.

                  (e) Governmental Approvals and Consents. No authorization or

Documents to which Borrower is a party are the legal, valid and binding
obligations of Borrower enforceable against Borrower in accordance with their
respective terms (assuming due and valid authorization, execution and delivery
of this Agreement by any party other than 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. This facility will be used
by Borrower for general corporate purposes, including support for commercial
paper issued by Borrower. Neither Borrower nor any Subsidiary of 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 Borrower will be used for any
purpose that would violate the provisions of the margin regulations of the
Board.

                  (h) Title to Properties. Each of Borrower and any Subsidiary
of Borrower has good title to the Properties reflected in the financial
statements referred to in Section 7.01(m) and in any financial statements
delivered pursuant to Section 8.01(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 Borrower or any Subsidiary of Borrower or that have been disposed of

to Section 8.02(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 (i) in the case of the Property of Borrower, the Mortgage and Liens
permitted by the Mortgage; (ii) Liens that do not interfere with the use of such
Properties for the purposes for which they are held; (iii) minor Liens and
defects of title that are not material either individually or in the aggregate;
and (iv) Permitted Liens.

                                                                              34

                  (i) Investment Company Act; PUHC Act of 1935. Neither Borrower

has been no change in the consolidated financial position, results of
operations, business or prospects of Borrower and any Consolidated Subsidiaries
of Borrower that would have a Material Adverse Effect on Borrower.

                  (k) Litigation. There is no litigation, action, suit or other
legal or governmental proceeding pending or, to the best knowledge of 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 (ii) in which
there is a reasonable possibility of an adverse decision that is likely to have
a Material Adverse Effect on Borrower.

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 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 7.01(l), is likely to result in a material liability or
deficiency of Borrower or any Significant Subsidiary. As used in this Section
7.01(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
7.01(l) at any one time outstanding, individually and in the aggregate, is less
than $25,000,000.

                  (m) Financial Statements. The audited financial statements of
Borrower as of and for the year ended December 31, 2000 and the unaudited
financial statements of Borrower as of and for the three months ended March 31,
2001, copies of which have been delivered to the Banks, present fairly the
financial condition and results of operations of Borrower as of such dates and
for the periods then ended, in conformity with GAAP and, except as otherwise
stated therein, consistently applied.

                  (n) Accuracy of Information. None of the documents or written
information (excluding financial projections and forecasts) provided by Borrower
to the Banks in connection with or pursuant to this Agreement 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 necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. The financial projections and
forecasts furnished to the Banks by Borrower with respect to the transactions
contemplated under this Agreement were prepared in good faith and on the basis
of information and assumptions that Borrower believed to be reasonable as of the
date of such information.

                  (o) No Violation. 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 on Borrower.

Subsidiary with their respective officers and independent certified public
accountants; subject, however, in all cases to the imposition of such conditions

reasonable considerations of safety and security. 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 requirements or

time when a Default or an Event of Default shall have occurred and be
continuing.

                  (f) Insurance. And will cause each Significant Subsidiary to,

any Significant Subsidiary to sell, assign, transfer or otherwise dispose of any

Subsidiary of Borrower that constitutes a Significant Subsidiary after giving
effect to such transaction; provided, that immediately before and after giving
effect to such sale, assignment, transfer or other disposition, no Event of
Default or Default shall have occurred and be continuing. Notwithstanding the
foregoing provisions of this Section 8.02(b), 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 more bona fide transactions to
third parties.

                  (c) Consolidation, Merger or Disposal of Assets. And will not

liquidation, or conveyance, sale, transfer, lease or other disposition, no Event
of Default or Default shall have occurred and be continuing.

                  (d) Takeover Bid. Use the proceeds of any Loan made to it to
participate in any unsolicited control bid for any other Person.

         Section 8.03. Consent to Unregco IPO Transaction. The parties hereto
hereby agree that notwithstanding any provisions of the Loan Documents
(including, without limitation, Sections 8.01(d), 8.02(b) and 8.02(c) of this
Agreement) that might otherwise prohibit the Unregco IPO Transaction, the

Unregco IPO Transaction shall be permitted consistent with the definition
thereof, and no Default or Event of Default shall be deemed to have occurred
under the Loan Documents solely as a result thereof.

         Section 8.04. Consent to Restructuring. The parties hereto hereby agree
that notwithstanding any provisions of the Loan Documents (including, without
limitation, Sections 8.02(b) and 8.02(c) of this Agreement) that might otherwise
prohibit the Restructuring, the Restructuring (including without limitation the
distribution of the remaining 80% of the common stock of Unregco to shareholders
of Regco (as defined in Schedule 8.04)) shall be permitted consistent with the
definition thereof, and no Default or Event of Default shall be deemed to have
occurred under the Loan Documents solely as a result thereof. In addition,
notwithstanding the provisions of Section 8.02(a) and the default provisions
related thereto, if as a result of the Restructuring being partially completed
the Borrower is not in compliance with Section 8.02(a) at any time, such
non-compliance will not be a Default or Event of Default so long as Regco on a
pro forma consolidated basis would be in compliance with the financial covenant
set forth in Section 8.02(a) of either of the Regco Credit Facilities at such
time, if such covenant were then applicable, it being agreed that the foregoing
deemed compliance shall be available for 90 days following the first date on
which such test under Section 8.02(a) is not satisfied. Additionally, Unregco
and its Subsidiaries shall not be restricted by the representations, covenants
or events of default hereunder.

                                                                              41

thereto. Notwithstanding any provision to the contrary elsewhere in this
Agreement, the 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 Agent.

         Section 10.02. Delegation of Duties. The 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 Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

         Section 10.03. Exculpatory Provisions. Neither the Agent nor any of its
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 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
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 other Loan Document or for any failure of
Borrower to perform its obligations hereunder or thereunder. The Agent 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 Borrower.

         Section 10.04. Reliance by Agent. The Agent shall be entitled to rely,
and shall be fully protected in relying, upon any Note, writing, resolution,
notice, consent, certificate, affidavit, letter, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to Borrower), independent accountants and other experts
selected by the Agent. The 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 Agent. The 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 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 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,
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 10.05. Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from a Bank or 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 Agent receives such
a notice, the Agent shall give notice thereof to the Banks. The 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
Agent shall have received such directions, the 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 10.06. Non-Reliance on Agent and Other Banks. Each Bank
expressly acknowledges that neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates has made any
representations or warranties to it and that no act by the Agent hereinafter
taken, including any review of the affairs of Borrower, shall be deemed to
constitute any representation or warranty by the Agent to any Bank. Each Bank
represents to the Agent that it has, independently and without reliance upon the
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 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 the 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
Borrower. Except for notices, reports and other documents expressly required to
be furnished to the Banks by the Agent hereunder, the 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 Borrower that may come into the
possession of the Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates.

         Section 10.07. Indemnification. The Banks agree to indemnify the Agent
in its capacity as such (to the extent not reimbursed by Borrower and without
limiting the obligation of Borrower to do so), ratably according to their
respective applicable Pro Rata Percentages in effect on the date on which
indemnification is sought under this Section 10.07, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted against the Agent in any way relating to
or arising out of this Agreement, any of the other Loan Documents or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agent 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 solely from the Agent's gross negligence or willful misconduct. The
agreements in this Section 10.07 shall survive the payment of the Loans and all
other amounts payable hereunder.

         Section 10.08. Agent in Its Individual Capacity. The Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with Borrower as though the Agent were not the Agent hereunder
and under the other Loan Documents. With respect to its Loans made or renewed by
it and any Note issued to it, the 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 the Agent, and the terms "Bank" and "Banks" shall
include the Agent in its individual capacity.

         Section 10.09. Successor Agent. The Agent may resign as Agent upon 30
days' notice to the Banks and Borrower, and may be removed as Agent at any time
for cause by the Majority Banks. If the Agent shall resign or be removed as
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 Borrower, whereupon such successor agent
shall succeed to the rights, powers and duties of the Agent, and the term
"Agent" shall mean such successor agent effective upon such appointment and
approval, and the former Agent's rights, powers and duties as 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. If a successor Agent shall not have been so
<PAGE>
                                                                              43

appointed within said 30-day period, the Agent may then appoint a successor
Agent who shall be a financial institution that has total assets in excess of
$500,000,000 and who shall serve as Agent until such time, if any, as an Agent
shall have been appointed as provided above. After any retiring Agent's
resignation or removal as 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
Agent under this Agreement and the other Loan Documents.

                                   ARTICLE XI

                                  MISCELLANEOUS

         Section 11.01. 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 the provisions of this Section 11.01. The
Majority Banks may, or, with the written consent of the Majority Banks, the
Agent may, from time to time, (a) enter into with 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 Borrower hereunder or thereunder or (b) waive, on such terms and
conditions as the Majority Banks or the 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 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 affected thereby, (ii) amend, modify
or waive any provision of this Section or reduce the percentage specified in the
definition of Majority Banks, or consent to the assignment or transfer by
Borrower of any of its respective rights and obligations under this Agreement
and the other Loan Documents, in each case without the written consent of all
the Banks, or (iii) amend, modify or waive any provision of Article X without
the written consent of the then Agent. Any such waiver and any such amendment,
supplement or modification shall apply equally to each of the Banks and shall be
binding upon Borrower, the Banks, the Agent and all future holders of the
amounts payable hereunder. In the case of any waiver, Borrower, the Banks and
the Agent shall be restored to their former position and rights hereunder and
under any outstanding Notes and any 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 11.02. 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 telecopy), and, shall be deemed to
have been duly given or made when delivered by hand, or three days after being
deposited in the mail, postage prepaid, or, in the case of telecopy notice, when
received, addressed as follows in the case of Borrower and the Agent, and as set
forth in Schedule I in the case of the other parties hereto, or to such other

provided that any notice, request or demand to or upon the Agent or the Banks
pursuant to Sections 2.02, 3.02, 4.03, 4.07, 4.10, 5.02 and 5.05 shall not be
effective until received.

         Section 11.03. No Waiver; Cumulative Remedies. No failure to exercise
and no delay in exercising, on the part of the 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 11.04. 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
the execution and delivery of this Agreement.

         Section 11.05. Payment of Expenses and Taxes. Borrower agrees (a) to
pay or reimburse the Agent for all its reasonable out-of-pocket costs and
expenses incurred in connection with the development, preparation, negotiation
and execution of, and any amendment, supplement or modification to, this
Agreement 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 limitation, the
reasonable fees and disbursements of Simpson, Thacher & Bartlett, special
counsel to the Agent (but excluding the fees or expenses of any other counsel),
(b) to pay or reimburse each Bank and the 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 special counsel to the Agent and (c) without duplication of any other
provision contained in this Agreement or any Notes, to pay, indemnify, and hold
each Bank and the 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 (d) without duplication of any other provision contained in this
Agreement or any Notes, to pay, indemnify, and hold each Bank and the Agent
harmless from and against, any and all other liabilities, obligations, losses,
<PAGE>
                                                                              45

damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Agreement, any Notes, the
other Loan Documents and any such other documents (all the foregoing in this
clause (d), collectively, the "indemnified liabilities"); provided, that
Borrower shall have no obligation hereunder to the Agent or any Bank with
respect to indemnified liabilities arising from the gross negligence or willful
misconduct of the Agent or any such Bank; AND PROVIDED FURTHER, THAT IT IS THE
INTENTION OF BORROWER TO INDEMNIFY THE AGENT AND THE BANKS AGAINST THE
CONSEQUENCES OF THEIR OWN NEGLIGENCE. The agreements in this Section 11.05 shall
survive repayment of the Loans and all other amounts payable hereunder.

         Section 11.06. Effectiveness; Successors and Assigns; Participations;
Assignments. i) This Agreement shall become effective on July 13, 2001 (the
"Effective Date") and thereafter shall be binding upon and inure to the benefit
of Borrower, the Banks, the Agent, all future holders of the Loans and their
respective successors and assigns, except that 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 commercial
banking business and in accordance with applicable law, at any time sell to one
or more banks or other financial institutions (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 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 for all purposes under this Agreement
and the other Loan Documents, Borrower and the 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 11.01, 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. Borrower agrees that each Participant, to the extent provided in its
participation, shall be entitled to the benefits of Sections 4.05, 4.08, 5.01
and 5.03 with respect to its participation in the Commitments and the Loans
outstanding from time to time; provided, that 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. Except as expressly provided in this Section 11.06(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) Any Bank may, in the ordinary course of its commercial
banking business and in accordance with applicable law, at any time sell to any
Affiliate of such Bank that is a bank (a "Bank Affiliate") and, with the consent
of Borrower and the Agent (which in each case shall not be unreasonably withheld
and, in the case of Borrower, shall not be required if an Event of Default
exists), to one or more additional banks ("Purchasing Banks") all or any part of
its rights and obligations under this Agreement pursuant to a Committed Loan
Assignment and Acceptance ("Committed Loan Assignment and Acceptance"),
substantially in the form of Exhibit 11.06(c) executed by such Purchasing Bank
and such transferor Bank (and, in the case of a Purchasing Bank that is not a
Bank Affiliate, by Borrower and the Agent) and delivered to the Agent for its
acceptance and recording in the Register; provided, that 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. Upon such execution, delivery,
acceptance and recording, from and after the effective date determined pursuant
to such Committed Loan Assignment and Acceptance (the "Transfer Effective
Date"), (i) the Purchasing Bank thereunder shall be a party hereto and, to the
extent provided in such Committed Loan 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,
<PAGE>
                                                                              46

to the extent provided in such Committed Loan Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of a
Committed Loan 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 Committed Loan
Assignment and Acceptance shall be deemed to amend this Agreement to the extent,
and only to the extent, necessary to reflect the addition of such Purchasing
Bank and the resulting adjustment of Pro Rata 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 and the Loans. On or
prior to the Transfer Effective Date determined pursuant to such Committed Loan
Assignment and Acceptance, (i) appropriate entries shall be made in the accounts
of the transferor Bank and the Register evidencing such assignment and releasing
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 Register as
required by Section 4.01 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 Agent for return to the applicable
Borrower.

                  (d) Any Bank may, in the ordinary course of its commercial
banking business and in accordance with applicable law, at any time assign to
one or more banks or other financial institutions (a "CAF Loan Assignee") any
CAF Loan owing to such Bank, pursuant to a CAF Loan Assignment and Acceptance
executed by the assignor Bank and the CAF Loan Assignee. Upon such execution,
from and after the date of such CAF Loan Assignment and Acceptance, the CAF Loan
Assignee shall, to the extent of the assignment provided for in such CAF Loan
Assignment and Acceptance, be deemed to have the same rights and benefits of
payment and enforcement with respect to such CAF Loan and the same obligation to
share and rights of setoff pursuant to Sections 5.04 and 11.07 as it would have
had if it were a Bank hereunder; provided that unless such CAF Loan Assignment
and Acceptance shall otherwise specify and a copy of such CAF Loan Assignment
and Acceptance shall have been delivered to the Agent for its acceptance and
recording in the Register in accordance with Section 11.06(e), the assignor
thereunder shall act as collection agent for the CAF Loan Assignee thereunder,
and the Agent shall pay all amounts received from Borrower that are allocable to
the assigned CAF Loan directly to such assignor without any further liability to
such CAF Loan Assignee. A CAF Loan Assignee under a CAF Loan Assignment and
Acceptance shall not, by virtue of such CAF Loan Assignment and Acceptance,
become a party to this Agreement or have any rights to consent to or refrain
from consenting to any amendment, supplement, waiver or other modification of
any provision of this Agreement or any related document; provided that (i) the
assignor under such CAF Loan Assignment and Acceptance and such CAF Loan
Assignee may, in their discretion, agree between themselves upon the manner in
which such assignor will exercise its rights under this Agreement and any
related document and (ii) if a copy of such CAF Loan Assignment and Acceptance
shall have been delivered to the Agent for its acceptance and recording in the
Register in accordance with Section 11.06(e), neither the principal amount of,
the interest rate on, nor the maturity date of any CAF Loan assigned to the CAF
Loan Assignee thereunder will be reduced or postponed, as the case may be,
without the written consent of such CAF Loan Assignee. If a CAF Loan Assignee
has caused a CAF Loan Assignment and Acceptance to be recorded in the Register
in accordance with Section 11.06(e), such CAF Loan Assignee may thereafter, in
the ordinary course of its business and in accordance with applicable law,
assign such Individual CAF Loan to any Bank, to any Affiliate or Subsidiary of
such CAF Loan Assignee or to any other financial institution that has total
assets in excess of $1,000,000,000 and that in the ordinary course of its
business extends credit of the type evidenced by such Individual CAF Loan, and
the foregoing provisions of this Section 11.06(d) shall apply, mutatis mutandis,
to any such assignment by a CAF Loan Assignee. Except in accordance with the
preceding sentence, CAF Loans may not be further assigned by a CAF Loan
Assignee, subject to any legal or regulatory requirement that the CAF Loan
Assignee's assets must remain under its control.
<PAGE>
                                                                              47

                  (e) The Agent shall maintain at its address referred to in
Section 11.02 a copy of each CAF Loan Assignment and Acceptance and each
Committed Loan Assignment and Acceptance delivered to it and a register (the
"Register") for the recordation of (i) 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 and (ii) with respect to each CAF Loan Assignment and Acceptance
delivered to the Agent, the name and address of the CAF Loan Assignee and the
principal amount of each CAF Loan owing to such CAF Loan Assignee. To the extent
permitted by applicable law, the entries in the Register shall be conclusive, in
the absence of manifest error, and Borrower, the Agent and the Banks may (and,
in the case of any Loan or other obligation 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
Borrower or any Bank or any CAF Loan Assignee at any reasonable time and from
time to time upon reasonable prior notice.

                  (f) Upon its receipt of a Committed Loan 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 Borrower and the
Agent) together with payment to the Agent of a registration and processing fee
of (i) $3000 with respect to any Purchasing Bank that is not already a Bank or a
Bank Affiliate and (ii) $1000 with respect to any Purchasing Bank that is
already a Bank or a Bank Affiliate (which fee shall not be for the account of
Borrower), the Agent shall promptly accept such Committed Loan 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 Borrower. Upon its receipt of a CAF
Loan Assignment and Acceptance executed by an assignor Bank and a CAF Loan
Assignee, together with payment to the Agent of a registration and processing
fee of $500 (which fee shall not be for the account of Borrower), the Agent
shall promptly accept such CAF Loan Assignment and Acceptance, record the
information contained therein in the Register and give notice of such acceptance
and recordation to the assignor Bank, the CAF Loan Assignee and Borrower.

                  (g) Each Bank agrees to exercise its best efforts to keep, and
to cause any third party recipient of the information described in this Section
11.06(g) to keep, any information delivered or made available by Borrower to it
(including any information obtained pursuant to Section 8.01) that is clearly
indicated to be confidential information, confidential from anyone other than
Persons employed or retained by such Bank who are or are expected to become
engaged in evaluating, approving, structuring or administering the transactions
contemplated hereunder; provided that nothing herein shall prevent any Bank 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 Agent, any Bank, Borrower or their respective
Affiliates may be a party, (vi) to the extent reasonably required in connection
with the exercise of any remedy hereunder, (vii) to such Bank's legal counsel,
independent auditors and other professional advisors and (viii) to any actual or
proposed Participant, Purchasing Bank or CAF Loan Assignee (each, a
"Transferee") that has agreed in writing to be bound by the provisions of this
Section 11.06(g). Unless prohibited from doing so by applicable law, each Bank
will use its best efforts to notify Borrower of any information that it is
required or requested to deliver pursuant to clause (ii) of this Section
11.06(g) and, if Borrower is not a party to any such litigation, clause (v) of
this Section 11.06(g), prior to such Bank's delivery of such information.

                  (h) If, pursuant to this Section, 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
<PAGE>
                                                                              48

States or any state thereof, the transferor Bank shall cause such Transferee,
concurrently with the effectiveness of such transfer, (i) to represent to the
transferor Bank (for the benefit of the transferor Bank, the Agent and Borrower)
that under applicable law and treaties no taxes will be required to be withheld
by the Agent, Borrower or the transferor Bank with respect to any payments to be
made to such Transferee in respect of the Loans, (ii) to furnish to the
transferor Bank (and, in the case of any Purchasing Bank or CAF Loan Assignee
registered in the Register, the Agent and Borrower) either U.S. Internal Revenue
Service Form W-8BEN or U.S. Internal Revenue Service Form W-8EC1 (wherein such
Transferee claims entitlement to complete exemption from U.S. federal
withholding tax on all interest payments hereunder) and (iii) to agree (for the
benefit of the transferor Bank, the Agent and Borrower) to provide the
transferor Bank (and, in the case of any Purchasing Bank or CAF Loan Assignee
registered in the Register, the Agent and Borrower) a new Form W-8BEN or Form
W-8EC1 upon the expiration or obsolescence of any previously delivered form and
comparable statements in accordance with applicable U.S. laws and regulations
and amendments duly executed and completed by such Transferee, and to comply
from time to time with all applicable U.S. laws and regulations with regard to
such withholding tax exemption.

                  (i) Nothing herein shall prohibit any Bank from pledging or
assigning all or any portion of its Loans to any Federal Reserve Bank in
accordance with applicable law. In order to facilitate such pledge or
assignment, Borrower hereby agrees that, upon request of any Bank at any time
and from time to time after Borrower has made its initial Borrowing hereunder,
Borrower shall provide to such Bank, at Borrower's own expense, a promissory
note, substantially in the form of Exhibit 11.06(i)(a) or 11.06(i)(b) as the
case may be, evidencing the Committed Loans or CAF Loans, as the case may be,
owing to such Bank.

         Section 11.07. Setoff. In addition to any rights and remedies of the
Banks provided by law, each Bank shall have the right, without prior notice to
Borrower, any such notice being expressly waived by Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by
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 Borrower. Each Bank agrees promptly to notify Borrower and the 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 11.08. 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 Agent.

         Section 11.09. 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 11.10. Integration. This Agreement and the other Loan Documents
represent the agreement of Borrower, the Agent and the Banks with respect to the
subject matter hereof, and there are no promises, undertakings, representations
or warranties by the 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 11.11. GOVERNING LAW. II) THIS AGREEMENT AND ANY NOTES AND THE
RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND ANY NOTES SHALL
BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK.

                  (b) Notwithstanding anything in Section 11.11(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
Borrower agree that (i) if Article 1.04, Subtitle 1, Title 79, of the Revised
Civil Statutes of Texas, 1925, as amended, is applicable to such determination,
the indicated rated ceiling computed from time to time pursuant to Section (a)
of such Article shall apply, provided that, to the extent permitted by such
Article, the Agent may from time to time by notice to 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 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 11.12. Submission to Jurisdiction; Waivers. 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 Borrower
at its address set forth in Section 11.02 or at such other address of which the
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
referred to in this Section 11.12 any special, exemplary, punitive or
consequential damages.

         Section 11.13. Acknowledgments. 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;
<PAGE>
                                                                              50

                  (b) neither the Agent nor any Bank has any fiduciary
relationship with or duty to Borrower arising out of or in connection with this
Agreement or any of the other Loan Documents, and the relationship between the
Agent and the Banks, on one hand, and 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 Borrower
and the Banks.

         Section 11.14. Limitation on Agreements. All agreements between
Borrower, the 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 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 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 Loan or
the amounts owing on other obligations of Borrower to the 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 any Loan and the amounts owing
on other obligations of Borrower to the Agent or any Bank under any Loan
Document, as the case may be, such excess shall be refunded to Borrower. All
sums paid or agreed to be paid to the Agent or any Bank for the use, forbearance
or detention of the indebtedness of Borrower to the 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 11.14 shall control and supersede every other
provision of all Loan Documents.

         Section 11.15. Removal of Bank. Notwithstanding anything herein to the
contrary, Borrower may, at any time in its sole discretion, remove any Bank upon
15 Business Days' written notice to such Bank and the Agent (the contents of
which notice shall be promptly communicated by the 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 Borrower under
this Section 11.15 shall constitute a representation by Borrower that the
removal described in such notice is permitted under this Section 11.15.
Concurrently with such removal, Borrower shall pay to such removed Bank all
amounts owing to such Bank hereunder and under any Notes in immediately
available 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 Borrower from all
obligations owing to the

                                                                              51

removed Bank in respect of the Loans hereunder and surrender to the Agent for
return to Borrower any Notes of 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.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers or agents thereunto duly authorized, as of
the date first above written.

         Re: Retention Agreement

Dear Mr. Letbetter:

                  As it is our belief that your continued employment with
Reliant Resources, Inc. (the Company) is important for the growth and
development of the Company, the Company hereby agrees to provide R. Steve
Letbetter (the Executive) with the following stock award pursuant to the Reliant
Resources, Inc. Long-Term Incentive Plan, but only if the vesting requirements
set forth in this agreement are satisfied.

                  1. DEFINITIONS: For purposes of this agreement, the following
terms will have the meanings indicated below:

                  "AFFILIATE" shall mean any company controlled by, controlling
or under common control with the Company within the meaning of Section 414 of

perform Executive's duties, (c) intentional engagement in conduct which is
materially injurious to the Company or its Affiliates (monetarily or otherwise)
or (d) conviction of a felony or a misdemeanor involving moral turpitude. For
this purpose, an act or failure to act on the part of Executive will be deemed
"intentional" only if done or omitted to be done by Executive not in good faith
and without reasonable belief that his/her action or omission was in the best
interest of the Company, and no act or failure to act on the part of Executive
will be deemed "intentional" if it was due primarily to an error in judgment or
negligence.

                  A "CHANGE IN CONTROL" shall be deemed to have occurred upon
the occurrence of any of the following events:

                  (a) 30% OWNERSHIP CHANGE: Any Person makes an acquisition of
         Outstanding Voting Stock and is, immediately thereafter, the beneficial

                  (b) BOARD MAJORITY CHANGE: Individuals who are Incumbent
         Directors cease for any reason to constitute a majority of the members

         the beneficial owners of the Outstanding Voting Stock immediately prior
         to such Business Combination beneficially own, directly or indirectly,
         more than 70% of the then outstanding shares of voting stock of the
         parent corporation resulting from such Business Combination in
         substantially the same relative proportions as their ownership,
         immediately prior to such Business Combination, of the Outstanding
         Voting Stock, (ii) if the Business Combination involves the issuance or
         payment by the Company of consideration to another entity or its
         shareholders, the total fair market value of such consideration plus

         Directors), (iii) no Person (other than any corporation resulting from
         such Business Combination) beneficially owns, directly or indirectly,
         30% or more of the then outstanding shares of voting stock of the
         parent corporation resulting from such Business Combination and (iv) a
         majority of the members of the board of directors of the parent
         corporation resulting from such Business Combination were Incumbent

         Business Combination; or

                  (d) MAJOR ASSET DISPOSITIONS: Consummation of a Major Asset
         Disposition unless, immediately following such Major Asset Disposition,
         (i) individuals and entities that were beneficial owners of the
         Outstanding Voting Stock immediately prior to such Major Asset
         Disposition beneficially own, directly or indirectly, more than 70% of

                  "RETENTION PERIOD" shall mean the period commencing on the

                  "RETIREMENT" shall mean termination of employment with the

                  "WITHOUT CAUSE" shall mean without Cause and for reasons other

                  2. STOCK AWARD. Effective upon the Effective Date, Executive
has been granted, subject to the terms and conditions herein set forth, an award
(the "Stock Award") of 50,000 restricted shares of Common Stock. The Stock Award

Company evidencing the accrual in favor of the Executive of the unfunded right

                  3. EXECUTIVE'S RIGHT TO THE STOCK AWARD: The Stock Award is
subject to the following terms and conditions:

                           (a) Executive shall not have any rights as a
                  stockholder in respect of the Stock Award, and the rights of
                  Executive in respect of the shares of Common Stock deliverable
                  thereunder may not be sold, assigned, transferred, pledged or
                  otherwise encumbered, from the Effective Date unless and until
                  the Executive is registered as the holder of such Common Stock
                  on the records of the Company as provided in paragraph (c),
                  below, following the vesting of the Executive's rights with
                  respect to such Stock Award as provided herein.

                           (b) The Executive's right to receive the shares of
                  Common Stock underlying the Stock Award shall vest on March 6,
                  2006, provided that the Executive has remained in the
                  continuous employment of the Company or its Affiliates during
                  the Retention Period. If, during the Retention Period, the
                  Company or one of its Affiliates terminates the Executive's
                  employment for Cause or the Executive terminates employment
                  Without Good Reason, the Executive shall forfeit his right to
                  receive the Stock Award as of such termination. If, during the
                  Retention Period, the Company or one of its Affiliates
                  terminates the Executive's employment Without Cause, the
                  Executive terminates employment for

                  Good Reason, or the Executive's employment terminates by
                  reason of death, Disability, or Retirement, the Executive's
                  right to receive the Stock Award shall vest as of such
                  termination. Notwithstanding anything herein to the contrary,
                  upon any Change in Control of the Company, the Executive's
                  right to the Stock Award shall vest immediately upon such
                  Change in Control; however, registration and delivery of the
                  shares of Common Stock awarded pursuant to the Stock Award
                  shall be postponed until the first month of the first calendar
                  year following the calendar year in which Executive's
                  employment with the Company and its Affiliates is terminated,
                  as provided in paragraph (c) below, unless otherwise provided
                  in Section 6.

                           (c) If Executive's right to receive the shares of
                  Common Stock underlying the Stock Award has vested pursuant to
                  paragraph (b), above, the shares of Common Stock granted under
                  the Stock Award shall be registered in the name of the
                  Executive and certificates representing such shares of Common
                  Stock shall be delivered to the Executive during the first
                  month of the first calendar year following the calendar year
                  in which Executive's employment with the Company and its
                  Affiliates is terminated, unless otherwise provided in Section
                  6. In addition, upon delivery of the certificates representing
                  such shares of Common Stock, Executive shall also be entitled
                  to receive a cash payment equal to the sum of all dividends,
                  if any, announced or paid with respect to an equivalent number
                  of shares of Common Stock underlying the Stock Award after the
                  Effective Date but prior the date of such payment.

                  4. WITHHOLDING OF TAXES: The Company may withhold from any
benefits payable under this agreement all federal, state, city or other taxes as
may be required pursuant to any law or governmental regulation or ruling.

                  5. NO EMPLOYMENT AGREEMENT: Nothing in this agreement shall
give the Executive any rights to (or impose any obligations for) continued
employment by the Company or any Affiliate or subsidiary thereof or successor
thereto, nor shall it give such entities any rights (or impose any obligations)
with respect to continued performance of duties by the Executive.

                  6. NO ASSIGNMENT; SUCCESSORS: Executive's right to receive
payments or benefits hereunder shall not be assignable or transferable, whether
by pledge, creation of a security interest or otherwise, whether voluntary,
involuntary, by operation of law or otherwise, other than a transfer by will or
by the laws of descent or distribution, and in the event of any attempted
assignment or transfer contrary to this Section 6 the Company shall have no
liability to pay any amount so attempted to be assigned or transferred. This
agreement shall inure to the

benefit of and be enforceable by Executive's personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees.

                  This agreement shall be binding upon and inure to the benefit
of the Company, its successors and assigns (including, without limitation, any
company into or with which the Company may merge or consolidate by operation of
law or otherwise). The Company agrees that it will not effect a Major Asset
Disposition (as defined in paragraph 9 of the definition of Change in Control in
Section 1) unless either (a) the person or entity acquiring such assets or a
substantial portion thereof shall expressly assume by an instrument in writing
all duties and obligations of the Company hereunder or (b) prior to the
consummation of such Major Asset Disposition the Company has distributed to the
Executive a lump sum cash payment equal to the Fair Market Value of the Stock
Award immediately prior to such consummation.

                  7. ADJUSTMENTS:

                  (a) The existence of the Stock Award shall not affect in any
         manner the right or power of the Company or its stockholders to make or
         authorize any or all adjustments, recapitalizations, reorganizations or
         other changes in the capital stock of the Company or its business or
         any merger or consolidation of the Company, or any issue of bonds,
         debentures, preferred or prior preference stock (whether or not such
         issue is prior to, on a parity with or junior to the Common Stock) or
         the dissolution or liquidation of the Company, or any sale or transfer
         of all or any part of its assets or business, or any other corporate
         act or proceeding of any kind, whether or not of a character similar to
         that of the acts or proceedings enumerated above.

                  (b) In the event of any subdivision or consolidation of
         outstanding shares of Common Stock, declaration of a dividend payable
         in shares of Common Stock or other stock split, then the number of
         shares of Common Stock covered by the Stock Award shall be
         proportionately adjusted by the Board as appropriate to reflect such
         transaction. In the event of any other recapitalization or capital
         reorganization of the Company, any consolidation or merger of the
         Company with another corporation or entity, the adoption by the Company
         of any plan of exchange affecting the Common Stock or any distribution
         to holders of Common Stock of securities or property (other than normal
         cash dividends or dividends payable in Common Stock), the Board shall
         make appropriate adjustments to the number of shares of Common Stock
         covered by the Stock Award, to reflect such transaction; provided that
         such adjustments shall only be such as are necessary to maintain the
         proportionate interest of the holder of the Stock Award and preserve,
         without increasing, the value of such Stock Award.

                  8. RESTRICTIONS: No Common Stock or other form of payment
shall be issued with respect to the Stock Award unless the Company shall be
satisfied based on the advice

of its counsel that such issuance will be in compliance with applicable federal
and state securities laws. Certificates evidencing shares of Common Stock
delivered under this agreement may be subject to such stop transfer orders and
other restrictions as the Company may deem advisable under the rules,
regulations and other requirements of the Securities and Exchange Commission,
any securities exchange or transaction reporting system upon which the Common
Stock is then listed or to which it is admitted for quotation and any applicable
federal or state securities law. The Company may cause a legend or legends to be
placed upon such certificates to make appropriate reference to such
restrictions.

                  9. ENTIRE AGREEMENT: This agreement represents the entire
agreement between the Company and Executive with respect to the subject matter
hereof, and supersedes and is in full substitution for any and all prior
agreements or understandings, whether oral or written, relating to the subject
matter hereof.

                  10. MODIFICATION OF AGREEMENT. Any modification of this
agreement shall be binding only if evidenced in writing and signed by an
authorized representative of the Company.

                  11. APPLICABLE LAW: This agreement is entered into under, and
shall be governed for all purposes by, the laws of the State of Texas.

                  12. SEVERABILITY: If a court of competent jurisdiction
determines that any provision of this agreement is invalid or unenforceable,
then the invalidity or unenforceability of that provision shall not affect the
validity or enforceability of any other provision of this agreement and all
other provisions shall remain in full force and effect.
