               364-DAY COMPETITIVE ADVANCE AND REVOLVING CREDIT FACILITY
AGREEMENT dated as of September 25, 2000, among LUCENT TECHNOLOGIES INC., a
Delaware corporation (the "Initial Borrower"), AVAYA INC., a Delaware
corporation (the "Subsequent Borrower"), the lenders listed in Schedule 2.01
(the "Lenders"), CITIBANK, N.A., a New York banking corporation, as agent for
the Lenders (in such capacity, the "Agent"), SALOMON SMITH BARNEY INC., as Lead
Arranger, BANK ONE, NA, THE CHASE MANHATTAN BANK and DEUTSCHE BANK AG NEW YORK
AND/OR CAYMAN ISLANDS BRANCHES, as Co-Syndication Agents and Co-Arrangers, and
COMMERZBANK AG, as Co-Arranger.

               The Initial Borrower and the Subsequent Borrower have requested
the Lenders to extend credit to the Borrower (as herein defined) to enable them
to borrow on a standby revolving credit basis on and after the date hereof and
at any time and from time to time prior to the Maturity Date (as herein defined)
a principal amount not in excess of $850,000,000 at any time outstanding. The
Initial Borrower and the Subsequent Borrower have also requested the Lenders to
provide a procedure pursuant to which the Borrower may invite the Lenders to bid
on an uncommitted basis on borrowings by the Borrower. The proceeds of such
borrowings are to be used for general corporate purposes, including refunding of
debt, support for commercial paper and acquisition financing. The Lenders are
willing to extend such credit to the Borrower on the terms and subject to the
conditions herein set forth.

               Accordingly, the Initial Borrower, the Subsequent Borrower, the
Lenders and the Agent agree as follows:

                                   ARTICLE I

                                  Definitions

               SECTION 1.01. Defined Terms. As used in this Agreement, the
following terms shall have the meanings specified below:

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

               "ABR Loan" shall mean any Committed Loan bearing interest at a
rate determined by reference to the Alternate Base Rate in accordance with the
provisions of Article II.

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

               "Administrative Questionnaire" shall mean an Administrative
Questionnaire containing contact information for each Lender in form
satisfactory to the Agent.

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

<PAGE>   6

               "Alternate Base Rate" shall mean, for any day, a rate per annum
equal to the greater of (a) the Base Rate in effect on such day and (b) the
Federal Funds Effective Rate in effect on such day plus 1/2 of 1%. For purposes
hereof, "Base Rate" shall mean the rate of interest per annum publicly announced
from time to time by the Agent as its base rate in effect at its principal
office in New York City; each change in the Base Rate shall be effective on the
date such change is publicly announced as effective. For purposes hereof,
"Federal Funds Effective Rate" shall mean, for any day, the weighted average of
the rates on overnight Federal funds transactions with members of the Federal
Reserve System arranged by Federal funds brokers, as published for such day (or,
if such day is not a Business Day, for the next preceding Business Day) by the
Federal Reserve Bank of New York, or, if such rate is not so published for any
day which is a Business Day, the arithmetic average, as determined by the Agent,
of the quotations for the day of such transactions received by the Agent from
three Federal funds brokers of recognized standing selected by it. If for any
reason the Agent shall have determined (which determination shall be conclusive
absent manifest error) that it is unable to ascertain the Federal Funds
Effective Rate for any reason, including the inability or failure of the Agent
to obtain sufficient quotations in accordance with the terms thereof, the
Alternate Base Rate shall be determined without regard to clause (b) of the
first sentence of this definition until the circumstances giving rise to such
inability no longer exist. Any change in the Alternate Base Rate due to a change
in the Base Rate or the Federal Funds Effective Rate shall be effective on the
effective date of such change in the Base Rate or the Federal Funds Effective
Rate, respectively.

               "Applicable Margin" shall mean (a) for ABR Loans, 0% per annum
and (b) for Eurodollar Committed Loans, a percentage per annum determined by
reference to the Public Debt Rating in effect on such date as set forth below:

                                   ARTICLE II

                                   The Credits

               SECTION 2.01. Commitments. Subject to the terms and conditions
and relying upon the representations and warranties herein set forth, each
Lender agrees, severally and not jointly, to make Committed Loans to the
Borrower, at any time and from time to time on and after the date hereof and
until the earlier of the Maturity Date and the termination of the Commitment of
such Lender, in an aggregate principal amount at any time outstanding not to
exceed such Lender's Commitment minus the amount by which the Competitive Loans
outstanding at such time shall be deemed to have used such Commitment pursuant
to Section 2.16, subject, however, to the conditions that (i) at no time shall
(A) the sum of (x) the outstanding aggregate principal amount of all Committed
Loans made by all Lenders plus (y) the outstanding aggregate principal amount of
all Competitive Loans made by all Lenders exceed (B) the Total Commitment, and
(ii) at all times the outstanding aggregate principal amount of all Committed
Loans made by each Lender shall equal the product of (A) the percentage which
its Commitment represents of the Total Commitment times (B) the outstanding
aggregate principal amount of all Committed Loans made pursuant to Section 2.04.
Each Lender's Commitment is set forth opposite its name in Schedule 2.01. Such
Commitments may be terminated or reduced from time to time pursuant to Section
2.11.

               Within the foregoing limits, the Borrower may borrow, pay or
prepay and reborrow Committed Loans hereunder, on and after the Closing Date and
prior to the Maturity Date, subject to the terms, conditions and limitations set

               SECTION 2.02. Loans. (a) Each Committed Loan shall be made as
part of a Borrowing consisting of Loans made by the Lenders ratably in
accordance with their respective Commitments; provided, however, that the
failure of any Lender to make any Committed Loan shall not in itself relieve any
other Lender of its obligation to lend hereunder (it being

                                       12
<PAGE>   17

understood, however, that no Lender shall be responsible for the failure of any
other Lender to make any Loan required to be made by such other Lender). Each
Competitive Loan shall be made in accordance with the procedures set forth in
Section 2.03. The Committed Loans or Competitive Loans comprising any Borrowing
shall be (i) in the case of Competitive Loans, in an aggregate principal amount
which is an integral multiple of $1,000,000 and not less than $10,000,000 and
(ii) in the case of Committed Loans, in an aggregate principal amount which is
an integral multiple of $1,000,000 and not less than $10,000,000 (or an
aggregate principal amount equal to the remaining balance of the available
Commitments).

               (b)   Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Committed Borrowing
shall be comprised entirely of Eurodollar Committed Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or 2.04, as applicable. Each
Lender may at its option make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any
exercise of such option shall not affect the obligation of the Borrower to repay
such Loan in accordance with the terms of this Agreement. Borrowings of more
than one Type may be outstanding at the same time; provided, however, that the
Borrower shall not be entitled to request any Borrowing which, if made, would
result in an aggregate of more than 10 separate Committed Borrowings comprised
of Eurodollar Committed Loans being outstanding hereunder at any one time. For
purposes of the foregoing, Loans having different Interest Periods, regardless
of whether they commence on the same date, shall be considered separate Loans.

               (c)   Subject to Section 2.05, each Lender shall make each Loan
to be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Agent in New York, New York, not later than
12:00 noon, New York City time, and the Agent shall by 3:00 p.m., New York City
time, credit the amounts so received to the general deposit account of the
Borrower with the Agent or, if a Borrowing shall not occur on such date because
any condition precedent herein specified shall not have been met, return the
amounts so received to the respective Lenders. Competitive Loans shall be made
by the Lender or Lenders whose Competitive Bids therefor are accepted pursuant
to Section 2.03 in the amounts so accepted. Committed Loans shall be made by the
Lenders pro rata in accordance with Section 2.16. Unless the Agent shall have
received notice from a Lender prior to the date of any Borrowing that such
Lender will not make available to the Agent such Lender's portion of such
Borrowing, the Agent may assume that such Lender has made such portion available
to the Agent on the date of such Borrowing in accordance with this paragraph (c)
and the Agent may, in reliance upon such assumption, make available to the
Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have made such portion available to the Agent, such Lender and
the Borrower severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Agent at (i) in the case of the Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, the Federal Funds Effective Rate. If such Lender shall
repay to the Agent such corresponding amount, such amount shall constitute such
Lender's Loan as part of such Borrowing for purposes of this Agreement.

               SECTION 2.03. Competitive Bid Procedure. (a) In order to request
Competitive Bids, the Borrower shall hand deliver or telecopy to the Agent a
duly completed Competitive Bid

                                       13
<PAGE>   18

Request in the form of Exhibit A-1 hereto, to be received by the Agent (i) in
the case of a Eurodollar Competitive Borrowing, not later than 10:00 a.m., New
York City time, four Business Days before a proposed Competitive Borrowing and
(ii) in the case of a Fixed Rate Borrowing, not later than 10:00 a.m., New York
City time, one Business Day before a proposed Competitive Borrowing. No ABR Loan
shall be requested in, or made pursuant to, a Competitive Bid Request. A
Competitive Bid Request that does not conform substantially to the format of
Exhibit A-1 may be rejected in the Agent's sole discretion, and the Agent shall
promptly notify the Borrower of such rejection by telecopy. Each Competitive Bid
Request shall refer to this Agreement and specify (x) whether the Borrowing then
being requested is to be a Eurodollar Borrowing or a Fixed Rate Borrowing, (y)
the date of such Borrowing (which shall be a Business Day) and the aggregate
principal amount thereof which shall be in a minimum principal amount of
$10,000,000 and in an integral multiple of $1,000,000, and (z) the Interest
Period with respect thereto (which may not end after the Maturity Date) and the
interest payment date or dates relating thereto. Promptly after its receipt of a
Competitive Bid Request that is not rejected as aforesaid, the Agent shall
invite by telecopy (in the form set forth in Exhibit A-2 hereto) the Lenders to
bid, on the terms and conditions of this Agreement, to make Competitive Loans
pursuant to the Competitive Bid Request.

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

               (c)   The Agent shall promptly notify the Borrower, by telecopy,
of all the Competitive Bids made, the Competitive Bid Rate and the principal
amount of each Competitive Loan in respect of which a Competitive Bid was made
and the identity of the Lender that made

                                       14
<PAGE>   19

each bid. The Agent shall send a copy of all Competitive Bids to the Borrower
for its records as soon as practicable after completion of the bidding process
set forth in this Section 2.03.

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

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

               (f)   A Competitive Bid Request shall not be made within five
Business Days after the date of any previous Competitive Bid Request. No
Competitive Borrowing shall be requested or made hereunder if after giving
effect thereto any of the conditions set forth in Section 2.01 would not be met.

               (g)   If the Agent shall elect to submit a Competitive Bid in its
capacity as a Lender, it shall submit such bid directly to the Borrower one
quarter of an hour earlier than the

                                       15
<PAGE>   20

latest time at which the other Lenders are required to submit their bids to the
Agent pursuant to paragraph (b) above.

               (h)   Upon the request of any Lender making a Competitive Loan,
the indebtedness of the Borrower resulting from such Competitive Loan shall be
evidenced by a separate promissory note of the Borrower in substantially the
form of Exhibit A-5 hereto payable to the order of the Lender making such
Competitive Loan.

               (i)   All notices required by this Section 2.03 shall be given in
accordance with Section 8.01.

               SECTION 2.04. Committed Borrowing Procedure. In order to request
a Committed Borrowing, the Borrower shall hand deliver or telecopy to the Agent
a duly completed Committed Borrowing Request in the form of Exhibit A-6 (a) in
the case of a Eurodollar Committed Borrowing, not later than 10:30 a.m., New
York City time, three Business Days before a proposed Borrowing and (b) in the
case of an ABR Borrowing, not later than 10:30 a.m., New York City time, on the
day of a proposed Borrowing. No Fixed Rate Loan shall be requested or made
pursuant to a Committed Borrowing Request. Such notice shall be irrevocable and
shall in each case specify (i) whether the Borrowing then being requested is to
be a Eurodollar Committed Borrowing or an ABR Borrowing; (ii) the date of such
Committed Borrowing (which shall be a Business Day) and the amount thereof; and
(iii) if such Borrowing is to be a Eurodollar Committed Borrowing, the Interest
Period with respect thereto, which shall not end after the Maturity Date. If no
election as to the Type of Committed Borrowing is specified in any such notice,
then the requested Committed Borrowing shall be an ABR Borrowing. If no Interest
Period with respect to any Eurodollar Committed Borrowing is specified in any
such notice, then the Borrower shall be deemed to have selected an Interest
Period of one month's duration. Notwithstanding any other provision of this
Agreement to the contrary, the Borrower shall not be entitled to request any
Committed Borrowing if the Interest Period requested with respect to such
Committed Borrowing would end after the Maturity Date. The Agent shall promptly
advise the Lenders of any notice given pursuant to this Section 2.04 and of each
Lender's portion of the requested Borrowing.

               SECTION 2.05. Conversion and Continuation of Committed Loans.
The Borrower shall have the right at any time upon prior irrevocable notice to
the Agent (i) not later than 10:30 a.m., New York City time, on the day of the
conversion, to convert all or any part of any Eurodollar Committed Borrowing
into an ABR Borrowing, (ii) not later than 10:30 a.m., New York City time, three
Business Days prior to conversion or continuation, to convert any ABR Borrowing
into a Eurodollar Committed Borrowing or to continue any Eurodollar Committed
Borrowing as a Eurodollar Committed Borrowing for an additional Interest Period
and (iv) not later than 10:30 a.m., New York City time, three Business Days
prior to conversion, to convert the Interest Period, with respect to any
Eurodollar Committed Borrowing to another permissible Interest Period, subject
in each case to the following:

               (a)   if less than all the outstanding principal amount of any
        Committed Borrowing shall be converted or continued, the aggregate
        principal amount of the Committed Borrowing converted or continued shall
        be an integral multiple of $1,000,000 and not less than $10,000,000;

                                       16
<PAGE>   21

               (b)   accrued interest on a Committed Borrowing (or portion
        thereof) being converted shall be paid by the Borrower at the time of
        conversion;

               (c)   if any Eurodollar Committed Borrowing is converted at a
        time other than the end of the Interest Period applicable thereto, the
        Borrower shall pay, upon demand, any amounts due to the Lenders pursuant
        to Section 2.15;

               (d)   any portion of a Committed Borrowing maturing or required
        to be repaid in less than one month may not be converted into or
        continued as a Eurodollar Committed Borrowing;

               (e)   any portion of a Eurodollar Committed Borrowing which
        cannot be continued as a Eurodollar Committed Borrowing by reason of
        clause (d) above shall be automatically converted at the end of the
        Interest Period in effect for such Eurodollar Committed Borrowing into
        an ABR Borrowing; and

               (f)   no Interest Period may be selected for any Eurodollar
        Committed Borrowing that would end later than the Maturity Date.

               Each notice of the Borrower pursuant to this Section 2.05 shall
be irrevocable and shall refer to this Agreement and specify (i) the identity
and amount of the Committed Borrowing that the Borrower requests to be converted
or continued, (ii) whether such Committed Borrowing is to be converted to or
continued as a Eurodollar Committed Borrowing or an ABR Borrowing, (iii) if such
notice requests a conversion, the date of such conversion (which shall be a
Business Day) and (iv) if such Committed Borrowing is to be converted to or
continued as a Eurodollar Committed Borrowing, the Interest Period with respect
thereto. If no Interest Period is specified in any such notice with respect to
any conversion to or continuation as a Eurodollar Committed Borrowing, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. If the Borrower shall not have given notice in accordance with this
Section 2.05 to convert or continue any Committed Borrowing, such Committed
Borrowing shall, at the end of the Interest Period applicable thereto (unless
repaid pursuant to the terms hereof), automatically be converted or continued
into a new Interest Period as an ABR Borrowing.

               SECTION 2.06. Fees. (a) The Borrower agrees to pay to each
Lender, through the Agent, on each March 31, June 30, September 30 and December
31 (with the first payment being due on September 30, 2000) and on the date on
which the Commitment of such Lender shall be terminated or reduced as provided
herein, a facility fee (a "Facility Fee") equal to the Applicable Percentage per
annum in effect from time to time on the average daily amount of the Commitment
of such Lender, whether used or unused, during the preceding quarter (or other
period commencing on the date of this Agreement, or ending with the Maturity
Date or any date on which the Commitment of such Lender shall be terminated or
reduced). All Facility Fees shall be computed on the basis of the actual number
of days elapsed in a year of 360 days. The Facility Fee due to each Lender shall
commence to accrue on the date of this Agreement, and shall cease to accrue on
the earlier of the Maturity Date and the termination of the Commitment of such
Lender as provided herein.

                                       17
<PAGE>   22

               (b)   The Borrower agrees to pay the Agent, for its own account,
the administrative and other fees referred to in the Fee Letter (the
"Administrative Fees") at the times and in the amounts agreed upon in the Fee
Letter.

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

               SECTION 2.07. Repayment of Loans; Evidence of Debt. (a) The
Borrower hereby agrees that the outstanding principal balance of each Committed
Loan shall be payable on the Maturity Date, and that the outstanding principal
balance of each Competitive Loan shall be payable on the last day of the
Interest Period applicable thereto. Each Loan shall bear interest on the
outstanding principal balance thereof as set forth in Section 2.08.

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

               (c)   The Agent shall maintain the Register pursuant to Section
8.04(d), and a subaccount for each Lender, in which Register and accounts (taken
together) shall be recorded (i) the amount of each Loan made hereunder, the Type
of each Loan made and the Interest Period applicable thereto, (ii) the amount of
any principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Agent hereunder from the Borrower and each Lender's share thereof.

               (d)   The entries made in the Register and accounts maintained
pursuant to paragraph (b) and (c) of this Section 2.07 shall, to the extent
permitted by applicable law, be prima facie evidence of the existence and
amounts of the obligations of the Borrower therein recorded; provided, however,
that the failure of any Lender or the Agent to maintain such account, such
Register or such subaccount, as applicable, or any error therein shall not in
any manner affect the obligation of the Borrower to repay the Loans made to the
Borrower by such Lender in accordance with their terms.

               (e)   The Borrower agrees that upon notice by any Lender after
the initial borrowing hereunder to the Borrower (with a copy to the Agent) to
the effect that a promissory note or other evidence of indebtedness is required
or appropriate in order for such Lender to evidence (whether for purposes of
pledge, enforcement or otherwise) the Committed Loans owing to, or to be made
by, such Lender, the Borrower shall promptly, execute and deliver to such
Lender, with a copy to the Agent, a promissory note or notes, in substantially
the form of Exhibit B hereto, payable to the order of such Lender in a principal
amount equal to the Commitment of such Lender.

               SECTION 2.08. Interest on Loans. (a) Subject to the provisions of
Section 2.09, the Loans comprising each Eurodollar Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to (i) in the

                                       18
<PAGE>   23

case of each Eurodollar Committed Loan, the LIBO Rate for the Interest Period in
effect for such Borrowing plus (x) the Applicable Margin from time to time in
effect plus (y) the Applicable Utilization Fee from time to time in effect and
(ii) in the case of each Eurodollar Competitive Loan, the LIBO Rate for the
Interest Period in effect for such Borrowing plus the Margin offered by the
Lender making such Loan and accepted by the Borrower pursuant to Section 2.03.

               (b)   Subject to the provisions of Section 2.09, the Loans
comprising each ABR Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be, for periods during which the Alternate Base Rate is determined by reference
to the Base Rate and 360 days for periods during which the Alternate Base Rate
is determined by reference to the Federal Funds Effective Rate) at a rate per
annum equal to the Alternate Base Rate from time to time in effect plus the
Applicable Margin from time to time in effect.

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

               (d)   Interest on each Loan shall be payable on each Interest
Payment Date applicable to such Loan except as otherwise provided in this
Agreement. The applicable LIBO Rate or Alternate Base Rate for each Interest
Period or day within an Interest Period, as the case may be, shall be determined
in good faith by the Agent, and such determination shall be conclusive absent
manifest error.

               (e)   Each Reference Bank agrees to furnish to the Agent timely
information for the purpose of determining each Eurodollar Loan and each LIBO
Rate. If any one or more of the Reference Banks shall not furnish such timely
information to the Agent for the purpose of determining any such interest rate,
the Agent shall determine such interest rate on the basis of timely information
furnished by the remaining Reference Banks. The Agent shall give prompt notice
to the Borrower and the Lenders of the applicable interest rate determined by
the Agent for purposes of Section 2.08(a), (b) or (c), and the rate, if any,
furnished by each Reference Bank for the purpose of determining the interest
rate under Section 2.08(a).

               (f)   If fewer than two Reference Banks furnish timely
information to the Agent for determining the LIBO Rate for any Eurodollar Loan,

               (i)   the Agent shall forthwith notify the Borrower and the
        Lenders that the interest rate cannot be determined for such Eurodollar
        Loans,

               (ii)  with respect to Eurodollar Loans, each such Loan will
        automatically, on the last day of the then existing Interest Period
        therefor, be prepaid by the Borrower or be automatically converted into
        a Base Rate Loan, and

               (iii) the obligation of the Lenders to make Eurodollar Loans or
        to convert Base Rate Loans into Eurodollar Loans shall be suspended
        until the Agent shall notify the Borrower and the Lenders that the
        circumstances causing such suspension no longer exist.

                                       19
<PAGE>   24

               (g)   Upon the occurrence and during the continuance of any Event
of Default under Section 6.01(b) or (c), (i) each Eurodollar Committed Loan will
automatically, on the last day of the then existing Interest Period therefor, be
converted into Base Rate Loans and (ii) the obligation of the Lenders to make,
or to convert Advances into, Eurodollar Committed Loans shall be suspended.

               SECTION 2.09. Default Interest. If the Borrower shall default in
the payment of the principal of or interest on any Loan or any other amount
becoming due hereunder, whether by scheduled maturity, notice of prepayment,
acceleration or otherwise, the Borrower shall on demand from time to time from
the Agent pay interest, to the extent permitted by law, on such defaulted amount
up to (but not including) the date of actual payment (after as well as before
judgment) at a rate per annum (computed on the basis of the actual number of
days elapsed over a year of 360 days) equal to the Alternate Base Rate plus 1%.

               SECTION 2.10. Alternate Rate of Interest. In the event, and on
each occasion, that on the day two Business Days prior to the commencement of
any Interest Period for a Eurodollar Borrowing the Agent shall have determined
in good faith (i) that dollar deposits in the principal amounts of the
Eurodollar Loans comprising such Borrowing are not generally available in the
London interbank market or (ii) that reasonable means do not exist for
ascertaining the LIBO Rate, the Agent shall, as soon as practicable thereafter,
give telecopy notice of such determination to the Borrower and the Lenders. In
the event of any such determination under clauses (i) or (ii) above, until the
Agent shall have advised the Borrower and the Lenders that the circumstances
giving rise to such notice no longer exist, (x) any request by the Borrower for
a Eurodollar Competitive Borrowing pursuant to Section 2.03 shall be of no force
and effect and shall be denied by the Agent and (y) any request by the Borrower
for a Eurodollar Committed Borrowing pursuant to Section 2.04 shall be deemed to
be a request for an ABR Borrowing. In the event a Lender notifies the Agent that
the rates at which dollar deposits are being offered will not adequately and
fairly reflect the cost to such Lender of making or maintaining its Eurodollar
Loan during such Interest Period, the Agent shall notify the Borrower of such
notice and until the Lender shall have advised the Agent that the circumstances
giving rise to such notice no longer exist, any request by the Borrower for a
Eurodollar Committed Borrowing shall be deemed a request for an ABR Borrowing
for the same Interest Period with respect to such Lender. Each determination by
the Agent hereunder shall be in good faith and conclusive absent manifest error.

               SECTION 2.11. Termination and Reduction of Commitments. (a) The
Commitments shall be automatically terminated on the Maturity Date.

               (b)   Upon at least three Business Days' prior irrevocable
telecopy notice to the Agent, the Borrower may at any time in whole permanently
terminate, or from time to time in part permanently reduce, the Total
Commitment; provided, however, that (i) each partial reduction of the Total
Commitment shall be in an integral multiple of $1,000,000 and in a minimum
principal amount of $10,000,000 and (ii) no such termination or reduction shall
be made which would reduce the Total Commitment to an amount less than the
aggregate outstanding principal amount of the Loans. Once terminated or reduced,
the Total Commitment may not be reinstated.

                                       20
<PAGE>   25

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

               SECTION 2.12. Prepayment. (a) The Borrower shall have the right
at any time and from time to time to prepay any Committed Borrowing, in whole or
in part, upon giving telecopy notice (or telephone notice promptly confirmed by
telecopy notice) to the Agent: (i) before 10:00 a.m., New York City time, two
Business Days prior to prepayment, in the case of Eurodollar Loans, and (ii)
before 10:00 a.m., New York City time, on the same Business Day of prepayment,
in the case of ABR Loans; provided, however, that each partial prepayment shall
be in an amount which is an integral multiple of $1,000,000 and not less than
$5,000,000. The Borrower shall not have the right to prepay any Competitive
Borrowing.

               (b)   On the date of any termination or reduction of the
Commitments pursuant to Section 2.11, the Borrower shall pay or prepay so much
of the Committed Borrowings as shall be necessary in order that the aggregate
principal amount of the Competitive Loans and Committed Loans outstanding will
not exceed the Total Commitment, after giving effect to such termination or
reduction.

               (c)   Each notice of prepayment from the Borrower shall specify
the prepayment date and the principal amount of each Borrowing (or portion
thereof) to be prepaid, shall be irrevocable and shall commit the Borrower to
prepay such Borrowing (or portion thereof) by the amount stated therein on the
date stated therein. All prepayments under this Section 2.12 shall be subject to
Section 2.15 but otherwise without premium or penalty. All prepayments under
this Section 2.12 shall be accompanied by accrued interest on the principal
amount being prepaid to the date of payment.

               SECTION 2.13. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall result in the imposition, modification or applicability of any
reserve, special deposit or similar requirement against assets of, deposits with
or for the account of or credit extended by any Lender, or shall result in the
imposition on such Lender or the London interbank market any other condition
affecting this Agreement, such Lender's Commitment or any Eurodollar Loan, or
Fixed Rate Loan made by such Lender, and the result of any of the foregoing
shall be to increase the cost to such Lender of making or maintaining any
Eurodollar Loan or Fixed Rate Loan or to reduce the amount of any sum received
or receivable by such Lender hereunder (whether of principal, interest or
otherwise) by an amount deemed by such Lender to be material, then the Borrower
will pay to such Lender upon demand such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.
Notwithstanding the foregoing, no Lender shall be entitled to request
compensation under this paragraph with respect to any Competitive Loan if the
change giving rise to such request was applicable to such Lender at the time of
submission of the Competitive Bid pursuant to which such Competitive Loan shall
have been made.

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

               (c)   A certificate of the Lender setting forth such amount or
0amounts (including computation of such amount or amounts) as shall be necessary
to compensate the Lender or its holding company as specified in paragraph (a) or
(b) above, as the case may be, shall be delivered to the Borrower and such
amount or amounts may be reviewed by the Borrower. Unless the Borrower disagrees
in good faith with the computation of the amount or amounts in such certificate,
the Borrower shall pay to the Lender, within 10 Business Days after receipt by
the Borrower of such certificate delivered by the Lender, the amount shown as
due on any such certificate. If the Borrower, after receipt of any such
certificate from the Lender, disagrees with the Lender on the computation of the
amount or amounts owed to the Lender pursuant to paragraph (a) or (b) above, the
Lender and the Borrower shall negotiate in good faith to promptly resolve such
disagreement. In either case, however, the Lender shall have a duty to mitigate
the damages that may arise as a consequence of paragraph (a) or (b) above to the
extent that such mitigation will not, in the judgment of the Lender, entail any
cost or disadvantage to the Lender that the Lender is not reimbursed or
compensated for by the Borrower.

               (d)   Failure on the part of any Lender to demand compensation
for any increased costs or reduction in amounts received or receivable or
reduction in return on capital with respect to any period shall not constitute a
waiver of such Lender's right to demand compensation with respect to any other
period; provided that if any Lender fails to make such demand within 45 days
after it obtains knowledge of the event giving rise to the demand such Lender
shall, with respect to amounts payable pursuant to this Section 2.13 resulting
from such event, only be entitled to payment under this Section 2.13 for such
costs incurred or reduction in amounts or return on capital from and after the
date 45 days prior to the date that such Lender does make such demand. The
protection of this Section shall be available to each Lender regardless of any
possible contention of the invalidity or inapplicability of the law, rule,
regulation, guideline or other change or condition which shall have occurred or
been imposed.

               SECTION 2.14. Change in Legality. (a) Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by 30 days' (or
such shorter period as shall be required in order to comply with applicable law)
written notice to the Borrower and to the Agent, such Lender may:

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

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

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

               (b)   For purposes of this Section 2.14, a notice to the Borrower
by any Lender shall be effective as to each Eurodollar Loan, if lawful, on the
last day of the Interest Period currently applicable to such Eurodollar Loan; in
all other cases such notice shall be effective on the date of receipt by the
Borrower.

               SECTION 2.15. Indemnity. The Borrower shall indemnify each Lender
against any out-of-pocket loss or expense which such Lender may sustain or incur
as a consequence of (a) any failure by the Borrower to borrow or to refinance,
convert or continue any Loan hereunder after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03, 2.04 or 2.05, (b) any payment, prepayment or conversion, or an
assignment required under Section 2.20, of a Eurodollar Loan by the Borrower
required by any other provision of this Agreement or otherwise made or deemed
made on a date other than the last day of the Interest Period, if any,
applicable thereto, (c) any default by the Borrower in payment or prepayment of
the principal amount of any Loan or any part thereof or interest accrued
thereon, as and when due and payable (at the due date thereof, whether by
scheduled maturity, acceleration, irrevocable notice of prepayment or otherwise)
or (d) the occurrence of any Event of Default.

               In the case of a Eurodollar Loan, such out-of-pocket loss or
expense shall be limited to an amount equal to the excess, if any, of (i) its
cost of obtaining the funds for the Loan being paid, prepaid, converted or not
borrowed, converted or continued (based on the LIBO Rate applicable thereto) for
the period from the date of such payment, prepayment, conversion or failure to
borrow, convert or continue to the last day of the Interest Period for such Loan
(or, in

                                       23
<PAGE>   28

the case of a failure to borrow, convert or continue, the Interest Period for
such Loan which would have commenced on the date of such failure) over (ii) the
amount of interest that would be realized by the Lender in reemploying the funds
so paid, prepaid, converted or not borrowed, converted or continued for such
period or Interest Period, as the case may be. In the case of an ABR Loan, such
out-of-pocket loss or expense shall be limited to an amount equal to the excess,
if any, of (i) its cost of obtaining the funds for the ABR Loan being paid,
prepaid, converted or not borrowed, converted or continued for the period from
the date of such payment, prepayment, conversion or failure to borrow, convert
or continue to the next Business Day for such ABR Loan over (ii) the amount of
interest that would be realized by the Lender in reemploying the funds so paid,
prepaid, converted or not borrowed, converted or continued until the next
Business Day, as the case may be.

               A certificate of the Lender setting forth such amount or amounts
(including the computation of such amount or amounts) as shall be necessary to
compensate the Lender or its holding company for the out-of-pocket expenses
defined herein shall be delivered to the Borrower and such amount or amounts may
be reviewed by the Borrower. If the Borrower, after receipt of any such
certificate from the Lender, disagrees in good faith with the Lender on the
computation of the amount owed to the Lender pursuant to this Section 2.15, the
Lender and the Borrower shall negotiate in good faith to promptly resolve such
disagreement.

               Each Lender shall have a duty to mitigate the damages to such
Lender that may arise as a consequence of clause (a), (b), (c) or (d) above to
the extent that such mitigation will not, in the judgment of such Lender, entail
any cost or disadvantage to such Lender that such Lender is not reimbursed or
compensated for by the Borrower.

               SECTION 2.16. Pro Rata Treatment. Except as required under
Sections 2.10, 2.13, 2.14, 2.15, 2.19 and 2.20, each Committed Borrowing, each
payment or prepayment of principal of any Committed Borrowing, each payment of
interest on the Committed Loans, each payment of the Facility Fees, each
reduction of the Commitments and each refinancing or conversion of any Borrowing
with a Committed Borrowing of any Type, shall be allocated pro rata among the
Lenders in accordance with their respective Commitments (or, if such Commitments
shall have expired or been terminated, in accordance with the respective
principal amounts of their outstanding Committed Loans). Each payment of
principal of any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
principal amounts of their outstanding Competitive Loans comprising such
Borrowing. Each payment of interest on any Competitive Borrowing shall be
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective amounts of accrued and unpaid interest on their
outstanding Competitive Loans comprising such Borrowing. For purposes of
determining the available Commitments of the Lenders at any time, each
outstanding Competitive Borrowing shall be deemed to have utilized the
Commitments of the Lenders (including those Lenders which shall not have made
Loans as part of such Competitive Borrowing) pro rata in accordance with such
respective Commitments. Each Lender agrees that in computing such Lender's
portion of any Borrowing to be made hereunder, the Agent may, in its discretion,
round each Lender's percentage of such Borrowing to the next higher or lower
whole dollar amount.

                                       24
<PAGE>   29

               SECTION 2.17. Sharing of Setoffs. Each Lender agrees that if it
shall, through the exercise of a right of banker's lien, setoff or counterclaim
against the Borrower, or pursuant to a secured claim under Section 506 of Title
11 of the United States Code or other security or interest arising from, or in
lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means,
obtain payment (voluntary or involuntary) in respect of any Committed Loan or
Loans as a result of which the unpaid principal portion of the Committed Loans
of such Lender shall be proportionately less than the unpaid principal portion
of the Committed Loans of any other Lender, it shall be deemed simultaneously to
have purchased from such other Lender at face value, and shall promptly pay to
such other Lender the purchase price for, a participation in the Committed Loans
of such other Lender, so that the aggregate unpaid principal amount of the
Committed Loans and participations in the Committed Loans held by each Lender
shall be in the same proportion to the aggregate unpaid principal amount of all
Committed Loans then outstanding as the principal amount of its Committed Loans
prior to such exercise of banker's lien, setoff or counterclaim or other event
was to the principal amount of all Committed Loans outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
however, that, if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.17 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Committed Loan deemed to have been so purchased may exercise any and all rights
of banker's lien, setoff or counterclaim with respect to any and all moneys
owing by the Borrower to such Lender by reason thereof as fully as if such
Lender had made a Committed Loan directly to the Borrower in the amount of such
participation.

               SECTION 2.18. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder from an account in the United States not later than 12:00
noon, New York City time, on the date when due in dollars to the Agent at its
offices at 399 Park Avenue, New York, NY 10043, in immediately available funds.

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

               SECTION 2.19. Taxes. (a) Any and all payments by the Borrower
hereunder shall be made, in accordance with Section 2.18, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto
imposed by the United States or any political subdivision or taxing authority
thereof, excluding taxes imposed on the Agent's or any Lender's (or any
transferee's or assignee's, including a participation holder's (any such entity
a "Transferee")) net income and franchise taxes imposed on the Agent or any
Lender (or Transferee) by the United States or any political subdivision or
taxing authority thereof (all such nonexcluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If the

                                       25
<PAGE>   30

Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder to any Lender (or any Transferee) or the Agent, (i) the
sum payable shall be increased by the amount necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.19) such Lender (or Transferee) or the Agent (as the case
may be) shall receive an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxing
authority or other Governmental Authority in accordance with applicable law.

               (b)   In addition, the Borrower agrees to pay any present or
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement imposed by the United States or any political subdivision or taxing
authority thereof (hereinafter referred to as "Other Taxes").

               (c)   The Borrower will indemnify each Lender (or Transferee) and
the Agent for the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes on amounts payable under this Section 2.19) paid by such Lender (or
Transferee) or the Agent, as the case may be, with respect to the Borrower and
any liability (including penalties, interest and reasonable out-of-pocket
expenses) arising therefrom or with respect thereto (other than any such
liability that results from the gross negligence or willful misconduct of the
Lender (or Transferee) or Agent), whether or not such Taxes or Other Taxes were
correctly or legally asserted by the relevant taxing authority or other
Governmental Authority. Such indemnification shall be made within 30 days after
the date any Lender (or Transferee) or the Agent, as the case may be, makes
written demand therefor. If the Borrower or any Lender (or Transferee) or the
Agent shall determine that Taxes or Other Taxes may not have been correctly or
legally assessed by the relevant taxing authority or other Governmental
Authority, and that a Lender (or Transferee) or the Agent may be entitled to
receive a refund in respect of Taxes or Other Taxes, it shall promptly notify
the other party of the availability of such refund and such Lender (or
Transferee) or the Agent shall, within 60 days after receipt of a request by the
Borrower, apply for such refund at the Borrower's expense. If any Lender (or
Transferee) or the Agent receives a refund or credit or offset against another
tax liability in respect of any Taxes or Other Taxes for which such Lender (or
Transferee) or the Agent has received payment from the Borrower hereunder it
shall promptly repay such refund or credit or offset against another tax
liability (including any interest received by such Lender (or Transferee) or the
Agent from the taxing authority with respect to the refund with respect to such
Taxes or Other Taxes) to the Borrower, net of all out-of-pocket expenses of such
Lender; provided that the Borrower, upon the request of such Lender (or
Transferee) or the Agent, agrees to return such refund or credit or offset
against another tax liability (plus penalties, interest or other charges) to
such Lender (or Transferee) or the Agent in the event such Lender (or
Transferee) or the Agent is required to repay such refund or credit or offset
against another tax liability. For purposes of the preceding sentence, the Agent
or any Lender shall determine in good faith and in its discretion the amount of
any credit or offset against another tax liability and shall be under no
obligation to make available to the Borrower any of its tax returns or any other
information that it deems to be confidential.

               (d)  As soon as practicable after the date of any payment of
Taxes or Other Taxes withheld by the Borrower in respect of any payment to any
Lender (or Transferee) or the

                                       26
<PAGE>   31

Agent, the Borrower will furnish to the Agent, at its address referred to in
Section 8.01, the original or a certified copy of a receipt evidencing payment
thereof.

               (e)   Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.19
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

               (f)   Each Lender (or Transferee) which is organized outside the
United States shall, prior to the due date of the first payment by the Borrower
to such Lender (or Transferee) hereunder, deliver to the Borrower such
certificates, documents or other evidence, as required by the Code or Treasury
Regulations issued pursuant thereto, including Internal Revenue Service Form
W-8BEN or Form W-8ECI and any other certificate or statement of exemption
required by Treasury Regulation Section 1.1441-1(a) or Section 1.1441-6(c) or
any subsequent version thereof, properly completed and duly executed by such
Lender (or Transferee) establishing that such payment is (i) not subject to
withholding under the Code because such payment is effectively connected with
the conduct by such Lender (or Transferee) of a trade or business in the United
States or (ii) totally exempt from United States tax under a provision of an
applicable tax treaty. Each such Lender (or Transferee) that changes its funding
office shall promptly notify the Borrower of such change and, upon written
request from the Borrower, shall deliver any new certificates, documents or
other evidence required pursuant to the preceding sentence prior to the
immediately following due date of any payment by the Borrower hereunder. Unless
the Borrower and the Agent have received forms or other documents satisfactory
to them indicating that payments hereunder are not subject to United States
withholding tax, notwithstanding paragraph (a), the Borrower or the Agent shall
withhold taxes from such payments at the applicable statutory rate in the case
of payments to or for any Lender (or Transferee) organized under the laws of a
jurisdiction outside the United States.

               (g)   The Borrower shall not be required to pay any additional
amounts to any Lender (or Transferee) in respect of Taxes and Other Taxes
pursuant to paragraphs (a), (b) and (c) above if the obligation to pay such
additional amounts would not have arisen but for a failure by such Lender (or
Transferee) to comply with the provisions of paragraph (f) above unless such
Lender (or Transferee) is unable to comply with paragraph (f) because of (i) a
change in applicable law, regulation or official interpretation thereof or (ii)
an amendment, modification or revocation of any applicable tax treaty or a
change in official position regarding the application or interpretation thereof,
in each case after the date hereof (and, in the case of a Transferee, after the
date of assignment or transfer).

               (h)   Any Lender (or Transferee) claiming any additional amounts
payable under this Section 2.19 shall (i) to the extent legally able to do so,
file any certificate or document if such filing would avoid the need for or
reduce the amount of any such additional amounts which may thereafter accrue,
and the Borrower shall not be obligated to pay such additional amounts if, any
Lender (or Transferee) could have filed such certificate or document and failed
to do so; or (ii) consistent with legal and regulatory restrictions, use
reasonable efforts to change the jurisdiction of its applicable lending office
if the making of such change would avoid the need for or reduce the amount of
any additional amounts which may thereafter accrue and would not, in the sole
determination of such Lender (or Transferee), be otherwise disadvantageous to
such Lender (or Transferee).

                                       27
<PAGE>   32

               SECTION 2.20. Mandatory Assignment; Commitment Termination. In
the event any Lender delivers to the Agent or the Borrower, as appropriate, a
certificate in accordance with Section 2.13(c) or a notice in accordance with
Section 2.10 or 2.14 or is a Defaulting Lender, or the Borrower is required to
pay any additional amounts or other payments in accordance with Section 2.19,
the Borrower may, at its own expense, and in its sole discretion (a) require
such Lender to transfer and assign in whole or in part, without recourse (in
accordance with Section 8.04), all or part of its interests, rights and
obligations under this Agreement (other than outstanding Competitive Loans) to
an assignee acceptable to the Agent which shall assume such assigned obligations
(which assignee may be another Lender, if a Lender accepts such assignment);
provided that (i) such assignment shall not conflict with any law, rule or
regulation or order of any court or other Governmental Authority and (ii) the
Borrower or such assignee shall have paid to the assigning Lender in immediately
available funds the principal of and interest accrued to the date of such
payment on the Loans made by it hereunder and all other amounts owed to it
hereunder or (b) terminate the Commitment of such Lender and prepay all
outstanding Loans (other than Competitive Loans) of such Lender; provided that
(x) such termination of the Commitment of such Lender and prepayment of Loans
does not conflict with any law, rule or regulation or order of any court or
Governmental Authority, (y) the Borrower shall have paid to such Lender in
immediately available funds the principal of and interest accrued to the date of
such payment on the Loans (other than Competitive Loans) made by it hereunder
and all other amounts owed to it hereunder and (z) the Borrower shall have paid
to the Agent a processing and recordation fee of $3,500 if such assignee is not
an existing Lender.

                     SECTION 2.21. Expansion of Commitments. The Borrower may
from time to time, and notwithstanding any prior reductions in the Total
Commitment by the Borrower, by notice to the Agent (which shall promptly deliver
a copy to each of the Lenders), request that the Total Commitment be increased
by an amount that is not less than $50,000,000 and will not result in the Total
Commitment under this Agreement exceeding $1,100,000,000. Each such notice shall
set forth the requested amount of the increase in the Total Commitment and the
date on which such increase is to become effective (which shall be not fewer
than 20 days after the date of such notice), and shall offer each Lender the
opportunity to increase its Commitment by its ratable share, based on the
amounts of the Lenders' Commitments, of the requested increase in the Total
Commitment. Each Lender shall, by notice to the Borrower and the Agent given not
more than 10 Business Days after the date of the Borrower's notice, either agree
to increase its Commitment by all or a portion of the offered amount or decline
to increase its Commitment (and any Lender that does not deliver such a notice
within such period of 10 Business Days shall be deemed to have declined to
increase its Commitment). In the event that, on the 10th Business Day after the
Borrower shall have delivered a notice pursuant to the first sentence of this
paragraph, the Lenders shall have agreed pursuant to the preceding sentence to
increase their Commitments by an aggregate amount less than the increase in the
Total Commitment requested by the Borrower, the Borrower shall have the right to
arrange for one or more banks or other financial institutions (any such assignee
Lender, bank or other financial institution being called an "Augmenting
Lender"), which may include any Lender, to extend Commitments or increase their
existing Commitments in an aggregate amount equal to all or part of the
unsubscribed amount, provided that each Augmenting Lender, if not already a
Lender hereunder, shall be subject to the approval of the Borrower and the Agent
(which approval shall not be unreasonably withheld), the commitment of each such
Augmenting Lender, if not already a Lender hereunder, shall not be less than
$25,000,000, and such Augmenting Lender shall execute all such

                                       28
<PAGE>   33

documentation as the Agent shall specify to evidence its status as a Lender
hereunder. If (and only if) Lenders (including Augmenting Lenders) shall have
agreed to increase their Commitments or to extend new Commitments in an
aggregate amount not less than $50,000,000, such increases and such new
Commitments shall become effective on the date specified in the notice delivered
by the Borrower pursuant to the first sentence of this paragraph, and shall be
deemed added to the Commitments set forth in Schedule 2.01 hereof.
Notwithstanding the foregoing, no increase in the Total Commitment (or in the
Commitment of any Lender) shall become effective under this paragraph unless, on
the date of such increase, the conditions set forth in paragraphs (b) and (c) of
Section 4.01 shall be satisfied (with all references in such paragraphs to a
Borrowing being deemed to be references to such increase) and the Agent shall
have received a certificate to that effect dated such date and executed by a
Responsible Officer of the Borrower.

               SECTION 2.22. Extension of Maturity Date. (a) The Borrower may,
by notice to the Agent (which shall promptly deliver a copy to each of the
Lenders) not less than 30 days and not more than 60 days prior to the Maturity
Date, request that the Lenders extend the Maturity Date for an additional 364
days from the Maturity Date then in effect hereunder (the "Existing Maturity
Date"). Each Lender shall, by notice to the Agent given not less than 20 days
and not more than 30 days prior to the Existing Maturity Date, advise the Agent
whether or not such Lender agrees to such extension (and any Lender that does
not advise the Agent on or before the 20th day prior to the Existing Maturity
Date shall be deemed to have advised the Agent that it will not agree to such
extension). The Agent shall, by notice to the Borrower given no later than 15
days prior to the Existing Maturity Date, inform the Borrower of the Lenders'
decisions to extend the Existing Maturity Date.

               (b)   The Borrower shall have the right on or before the Existing
Maturity Date to require any Lender which shall have advised or been deemed to
advise the Borrower that it will not agree to an extension of the Maturity Date
(each a "Non-Extending Lender") to transfer without recourse (in accordance with
and subject to the restrictions contained in Section 8.04, except that the
$3,500 processing fee set forth in Section 8.04(b)(iii) shall be paid by the
Borrower) all its interests, rights and obligations under this Agreement first,
to one or more existing Lenders and second, in the event the existing Lenders do
not accept the assignment of all of the Commitments of the Non-Extending
Lenders, to one or more other banks or other financial institutions (any such
assignee Lender, bank or other financial institution being called a "Substitute
Lender"), provided that (i) such Substitute Lender, if not already a Lender
hereunder, shall be subject to the approval of the Borrower and the Agent (which
approval shall not be unreasonably withheld) and shall execute all such
documentation as the Agent shall specify to evidence its status as a Lender
hereunder, (ii) such assignment shall become effective as of the Existing
Maturity Date and (iii) the Borrower shall pay to such Non-Extending Lender in
immediately available funds on the effective date of such assignment the
principal of and interest accrued to the date of payment on the Loans made by it
hereunder and all other amounts accrued for its account or owed to it hereunder.

               (c)   If (and only if) Lenders (including Substitute Lenders)
holding Commitments that represent at least 51% of the Total Commitment shall
have agreed to extend the Existing Maturity Date (the "Continuing Lenders"),
then, (i) the Maturity Date shall be extended to the date that is 364 days after
the Existing Maturity Date, and (ii) the Commitment

                                       29
<PAGE>   34

of each Non-Extending Lender (subject to any transfer and assignment pursuant to
paragraph (b) above) shall terminate (but such Lender shall continue to be
entitled to the benefits of Sections 2.13, 2.15, 2.19 and 8.05), and all Loans
of such Non-Extending Lender shall become due and payable, together with all
interest accrued thereon and all other amounts owed to such Lender hereunder, on
the Existing Maturity Date. The Maturity Date as so extended may be further
extended from time to time pursuant to this Section 2.22 but no more frequently
than once per fiscal year of the Borrower.

               Notwithstanding the foregoing, no extension of the Maturity Date
shall be effective with respect to any Lender unless, on and as of the Existing
Maturity Date, the conditions set forth in paragraphs (b) and (c) of Section
4.01 shall be satisfied (with all references in such paragraphs to a Borrowing
being deemed to be references to such extension) and the Agent shall have
received a certificate to that effect, dated the Existing Maturity Date, and
executed by a Responsible Officer of the Borrower.

                                  ARTICLE VII

                                    The Agent

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

            Neither the Agent nor any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them
except for its or his own gross negligence or willful misconduct, or be
responsible for any statement, warranty or representation herein or the contents
of any document delivered in connection herewith, or be required to ascertain or
to make any inquiry concerning the performance or observance by the Borrower of
any of the terms, conditions, covenants or agreements contained in this
Agreement. The Agent shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements. The Agent may deem and treat the
Lender which makes any Loan as the holder of the indebtedness resulting
therefrom for all purposes hereof until it shall have received notice from such
Lender, given as provided herein, of the transfer thereof. The Agent shall in
all cases be fully protected in acting, or refraining from acting, in accordance
with written instructions signed by the Required Lenders and, except as
otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders. The Agent shall,
in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or

                                       40
<PAGE>   45
persons. Neither the Agent nor any of its directors, officers, employees or
agents shall have any responsibility to the Borrower on account of the failure
of or delay in performance or breach by any Lender of any of its obligations
hereunder or to any Lender on account of the failure of or delay in performance
or breach by any other Lender or the Borrower of any of their respective
obligations hereunder or in connection herewith. The Agent may execute any and
all duties hereunder by or through agents or employees and shall be entitled to
rely upon the advice of legal counsel selected by it with respect to all matters
arising hereunder and shall not be liable for any action taken or suffered in
good faith by it in accordance with the advice of such counsel.

            The Lenders hereby acknowledge that the Agent shall be under no duty
to take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

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

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

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

                                       41
<PAGE>   46
gross negligence or willful misconduct of the Agent or any of its directors,
officers, employees or agents.

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

            Each Lender hereby acknowledges that none of the Lead Arranger, the
Co-Syndication Agents, the Co-Arrangers or any agent (other than the Agent)
designated on the signature pages hereof has any liability hereunder other than
in its capacity as a Lender.

            SECTION 8.02. Survival of Agreement. All covenants, agreements,

Borrower, the Agent and each Lender and their respective successors and assigns.

            SECTION 8.04. Successors and Assigns. (a) Whenever in this Agreement

of its interests, rights and obligations under this Agreement (including all or
a portion of its Commitment and the Loans at the time owing to it); provided,
however, that (i) the Borrower must give its prior written consent to such

this Agreement.

            (c) By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to

(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim, (ii)
except as set forth in (i) above, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or

represents and warrants that it is legally authorized to enter into such
Assignment and Acceptance; (iv) such assignee confirms that it has received a

information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (v) such assignee will
independently and without reliance upon the Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (vi) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto; and

all the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

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

            (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee together with an Administrative

                                       44
<PAGE>   49
consent of the Borrower to such assignment, the Agent shall (i) accept such
Assignment and Acceptance and (ii) record the information contained therein in
the Register.

            (f) Each Lender may, without the consent of the Borrower or the
Agent, sell participations to one or more banks or other entities in all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) each participating bank or other entity
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.13, 2.15 and 2.19 to the same extent as if it was the selling Lender,
except that all claims and petitions for payment and payments made pursuant to
such Sections shall be made through such selling Lender, and (iv) the Borrower,
the Agent and the other Lenders shall continue to deal solely and directly with
such selling Lender in connection with such Lender's rights and obligations
under this Agreement, and such Lender shall retain the sole right (and
participating banks or other entities shall have no right) to enforce the
obligations of the Borrower relating to the Loans and to approve any amendment,
modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the
Loans, or extending any scheduled principal payment date or date fixed for the
payment of interest on the Loans).

            Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure, each
such assignee or participant or proposed assignee or participant shall execute
an agreement whereby such assignee or participant shall agree to be bound by the
confidentiality restrictions included in the Information Memorandum dated August
11, 2000 used by the Agent in connection with the syndication of the
Commitments.

            (g) and shall agree (subject to customary exceptions) to preserve
the confidentiality of any such confidential information relating to the
Borrower.

            (h) Except in accordance with Section 8.13, the Borrower shall not
assign or delegate any of its respective rights and duties hereunder without the
prior written consent of all Lenders and any attempted assignment without such
consent shall be void.

            (i) Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute any
such Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, the Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes in the form of Exhibit A-5 or B hereto, as applicable, evidencing
the Loans made to the Borrower by the assigning Lender hereunder.

            SECTION 8.05. Expenses; Indemnity. (a) The Borrower agrees to pay
all reasonable out-of-pocket expenses incurred by the Agent in connection with
entering into this

                                       45

Agreement or in connection with any amendments, modifications or waivers of the
provisions hereof, or incurred by the Agent or any Lender in connection with the
enforcement or protection of their rights in connection with this Agreement or
in connection with the Loans made hereunder, including the fees and
disbursements of counsel for the Agent or, in the case of enforcement or
protection, Lenders.

            (b) The Borrower agrees to indemnify the Agent, the Lenders,
Affiliates, and their respective directors, officers, employees and agents (each
such person being called an "Indemnitee") against, and to hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related
expenses, including reasonable counsel fees and expenses, incurred by or
asserted against any Indemnitee arising out of (i) the execution or delivery of
this Agreement or any agreement or instrument contemplated thereby, the
performance by the parties thereto of their respective obligations thereunder or
the consummation of the transactions contemplated thereby, (ii) the use of the
proceeds of the Loans or (iii) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Indemnitee. Notwithstanding anything to the contrary stated
in this subsection (b), upon Distribution, the Subsequent Borrower hereby,
assumes all obligations of the Initial Borrower to indemnify the Indemnitees
under this Agreement and the Initial Borrower shall be released from all such
obligations.

            (c) The provisions of this Section 8.05 shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any investigation made by or on behalf of the
Agent or any Lender. All amounts due under this Section 8.05 shall be payable on
written demand therefor.

            SECTION 8.06. Right of Setoff. Upon (i) the occurrence and during
the continuance of any Event of Default and (ii) the making of the request
specified by Section 6.01 to authorize the Agent to declare the Loans due and
payable pursuant to the provisions of Section 6.01, each Lender and each of its
Affiliates is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender or such Affiliate to or for
the credit or the account of the Borrower against any and all of the obligations
of the Borrower now or hereafter existing under this Agreement, whether or not
such Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. Each Lender agrees promptly to notify the Borrower
after any such set off and application, provided that the failure to give such
notice shall not affect the validity of such setoff and application. The rights
of each Lender and its Affiliates under this Section are in addition to other
rights and remedies (including, without limitation, other rights of setoff) that
such Lender and its Affiliates may have.

            SECTION 8.07. Applicable Law. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

            SECTION 8.08. Waivers; Amendment. (a) No failure or delay of the
Agent or any Lender in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Agent and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies which
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) below, and then
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given. No notice or demand on the Borrower in any case
shall entitle the Borrower to any other or further notice or demand in similar
or other circumstances.

            (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior written
consent of each Lender affected thereby, (ii) increase the Commitment or
decrease the Facility Fee of any Lender without the prior written consent of
such Lender, or (iii) amend or modify the provisions of Section 2.16 or Section
8.04(h), the provisions of this Section or the definition of the "Required
Lenders," without the prior written consent of each Lender; provided further,
however, that no such agreement shall amend, modify or otherwise affect the
rights or duties of the Agent hereunder without the prior written consent of the
Agent. Each Lender shall be bound by any waiver, amendment or modification
authorized by this Section and any consent by any Lender pursuant to this
Section shall bind any assignee of its rights and interests hereunder.

            SECTION 8.09. Entire Agreement. This Agreement and the Fee Letter
constitute the entire contract among the parties relative to the subject matter
hereof. Any previous agreement among the parties with respect to the subject
matter hereof is superseded by this Agreement and the Fee Letter. Nothing in
this Agreement or the Fee Letter expressed or implied, is intended to confer
upon any party other than the parties hereto any rights, remedies, obligations
or liabilities under or by reason of this Agreement or the Fee Letter.

            SECTION 8.10. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

            SECTION 8.11. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 8.03.

            SECTION 8.12. Headings. Article and Section headings and the Table
of Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

            SECTION 8.13. Assignment, Delegation and Assumption. Upon the
Distribution, the rights and obligations of the Initial Borrower under this
Agreement will automatically, and without further act of the parties hereto, be
assigned and delegated to the Subsequent Borrower and the Subsequent Borrower
will automatically assume all such rights and obligations, including the
obligation to pay the principal of and all interest on any outstanding Loans,
all Fees and all other amounts from time to time owing hereunder, whether such
Loans shall have been made or such interest, fees or other amounts shall have
accrued prior to or after the date of such assignment, delegation and
assumption, such assignment, delegation and assumption to be effective as of the
date of the Distribution. At the time of the Distribution the Initial Borrower
will be released from all obligations under this Agreement and on any Loans and
from and after such time the Subsequent Borrower will be the "Borrower" and sole
obligor hereunder.

        FIVE YEAR COMPETITIVE ADVANCE AND REVOLVING CREDIT FACILITY AGREEMENT
dated as of September 25, 2000, among LUCENT TECHNOLOGIES INC., a Delaware
corporation (the "Initial Borrower"), AVAYA INC., a Delaware corporation (the
"Subsequent Borrower"), the lenders listed in Schedule 2.01 (the "Lenders"),
CITIBANK, N.A., a New York banking corporation, as agent for the Lenders (in
such capacity, the "Agent"), SALOMON SMITH BARNEY INC., as Lead Arranger, BANK
ONE, NA, THE CHASE MANHATTAN BANK and DEUTSCHE BANK AG NEW YORK AND/OR CAYMAN
ISLANDS BRANCHES, as Co-Syndication Agents and Co-Arrangers, and COMMERZBANK AG,
as Co-Arranger.

        The Initial Borrower and the Subsequent Borrower have requested the
Lenders to extend credit to the Borrower (as herein defined) to enable them to
borrow on a standby revolving credit basis on and after the date hereof and at
any time and from time to time prior to the Maturity Date (as herein defined) a
principal amount not in excess of $850,000,000 at any time outstanding. The
Initial Borrower and the Subsequent Borrower have also requested the Lenders to
provide a procedure pursuant to which the Borrower may invite the Lenders to bid
on an uncommitted basis on borrowings by the Borrower. The proceeds of such
borrowings are to be used for general corporate purposes, including refunding of
debt, support for commercial paper and acquisition financing. The Lenders are
willing to extend such credit to the Borrower on the terms and subject to the
conditions herein set forth.

        Accordingly, the Initial Borrower, the Subsequent Borrower, the Lenders
and the Agent agree as follows:

                                   ARTICLE I

                                   Definitions

        SECTION 1.01. Defined Terms. As used in this Agreement, the following
terms shall have the meanings specified below:

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

        "ABR Loan" shall mean any Committed Loan bearing interest at a rate
determined by reference to the Alternate Base Rate in accordance with the
provisions of Article II.

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

        "Administrative Questionnaire" shall mean an Administrative
Questionnaire containing contact information for each Lender in form
satisfactory to the Agent.

        "Affiliate" shall mean, when used with respect to a specified person,
another person that directly or indirectly controls or is controlled by or is
under common control with the person specified.
<PAGE>   6

        "Alternate Base Rate" shall mean, for any day, a rate per annum equal to
the greater of (a) the Base Rate in effect on such day and (b) the Federal Funds
Effective Rate in effect on such day plus 1/2 of 1%. For purposes hereof, "Base
Rate" shall mean the rate of interest per annum publicly announced from time to
time by the Agent as its base rate in effect at its principal office in New York
City; each change in the Base Rate shall be effective on the date such change is
publicly announced as effective. For purposes hereof, "Federal Funds Effective
Rate" shall mean, for any day, the weighted average of the rates on overnight
Federal funds transactions with members of the Federal Reserve System arranged
by Federal funds brokers, as published for such day (or, if such day is not a
Business Day, for the next preceding Business Day) by the Federal Reserve Bank
of New York, or, if such rate is not so published for any day which is a
Business Day, the arithmetic average, as determined by the Agent, of the
quotations for the day of such transactions received by the Agent from three
Federal funds brokers of recognized standing selected by it. If for any reason
the Agent shall have determined (which determination shall be conclusive absent
manifest error) that it is unable to ascertain the Federal Funds Effective Rate
for any reason, including the inability or failure of the Agent to obtain
sufficient quotations in accordance with the terms thereof, the Alternate Base
Rate shall be determined without regard to clause (b) of the first sentence of
this definition until the circumstances giving rise to such inability no longer
exist. Any change in the Alternate Base Rate due to a change in the Base Rate or
the Federal Funds Effective Rate shall be effective on the effective date of
such change in the Base Rate or the Federal Funds Effective Rate, respectively.

        "Applicable Margin" shall mean (a) for ABR Loans, 0% per annum and (b)
for Eurodollar Committed Loans, a percentage per annum determined by reference
to the Public Debt Rating in effect on such date as set forth below:

                                   ARTICLE II

                                   The Credits

        SECTION 2.01. Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make Committed Loans to the Borrower, at
any time and from time to time on and after the date hereof and until the
earlier of the Maturity Date and the termination of the Commitment of such
Lender, in an aggregate principal amount at any time outstanding not to exceed
such Lender's Commitment minus the amount by which the Competitive Loans
outstanding at such time shall be deemed to have used such Commitment pursuant
to Section 2.16, subject, however, to the conditions that (i) at no time shall
(A) the sum of (x) the outstanding aggregate principal amount of all Committed
Loans made by all Lenders plus (y) the outstanding aggregate principal amount of
all Competitive Loans made by all Lenders exceed (B) the Total Commitment, and
(ii) at all times the outstanding aggregate principal amount of all Committed
Loans made by each Lender shall equal the product of (A) the percentage which
its Commitment represents of the Total Commitment times (B) the outstanding
aggregate principal amount of all Committed Loans made pursuant to Section 2.04.
Each Lender's Commitment is set forth opposite its name in Schedule 2.01. Such
Commitments may be terminated or reduced from time to time pursuant to Section
2.11.

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

        SECTION 2.02. Loans. (a) Each Committed Loan shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments; provided, however, that the failure of any Lender
to make any Committed Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender shall
be responsible for the failure of any other Lender to make any Loan required to
be made by such other Lender). Each Competitive Loan shall be

                                       12
<PAGE>   17

made in accordance with the procedures set forth in Section 2.03. The Committed
Loans or Competitive Loans comprising any Borrowing shall be (i) in the case of
Competitive Loans, in an aggregate principal amount which is an integral
multiple of $1,000,000 and not less than $10,000,000 and (ii) in the case of
Committed Loans, in an aggregate principal amount which is an integral multiple
of $1,000,000 and not less than $10,000,000 (or an aggregate principal amount
equal to the remaining balance of the available Commitments).

        (b)      Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Committed Borrowing
shall be comprised entirely of Eurodollar Committed Loans or ABR Loans, as the
Borrower may request pursuant to Section 2.03 or 2.04, as applicable. Each
Lender may at its option make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any
exercise of such option shall not affect the obligation of the Borrower to repay
such Loan in accordance with the terms of this Agreement. Borrowings of more
than one Type may be outstanding at the same time; provided, however, that the
Borrower shall not be entitled to request any Borrowing which, if made, would
result in an aggregate of more than 10 separate Committed Borrowings comprised
of Eurodollar Committed Loans being outstanding hereunder at any one time. For
purposes of the foregoing, Loans having different Interest Periods, regardless
of whether they commence on the same date, shall be considered separate Loans.

        (c)      Subject to Section 2.05, each Lender shall make each Loan to be
made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Agent in New York, New York, not later than
12:00 noon, New York City time, and the Agent shall by 3:00 p.m., New York City
time, credit the amounts so received to the general deposit account of the
Borrower with the Agent or, if a Borrowing shall not occur on such date because
any condition precedent herein specified shall not have been met, return the
amounts so received to the respective Lenders. Competitive Loans shall be made
by the Lender or Lenders whose Competitive Bids therefor are accepted pursuant
to Section 2.03 in the amounts so accepted. Committed Loans shall be made by the
Lenders pro rata in accordance with Section 2.16. Unless the Agent shall have
received notice from a Lender prior to the date of any Borrowing that such
Lender will not make available to the Agent such Lender's portion of such
Borrowing, the Agent may assume that such Lender has made such portion available
to the Agent on the date of such Borrowing in accordance with this paragraph (c)
and the Agent may, in reliance upon such assumption, make available to the
Borrower on such date a corresponding amount. If and to the extent that such
Lender shall not have made such portion available to the Agent, such Lender and
the Borrower severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Agent at (i) in the case of the Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, the Federal Funds Effective Rate. If such Lender shall
repay to the Agent such corresponding amount, such amount shall constitute such
Lender's Loan as part of such Borrowing for purposes of this Agreement.

        SECTION 2.03. Competitive Bid Procedure. (a) In order to request
Competitive Bids, the Borrower shall hand deliver or telecopy to the Agent a
duly completed Competitive Bid Request in the form of Exhibit A-1 hereto, to be
received by the Agent (i) in the case of a Eurodollar Competitive Borrowing, not
later than 10:00 a.m., New York City time, four Business

                                       13
<PAGE>   18

Days before a proposed Competitive Borrowing and (ii) in the case of a Fixed
Rate Borrowing, not later than 10:00 a.m., New York City time, one Business Day
before a proposed Competitive Borrowing. No ABR Loan shall be requested in, or
made pursuant to, a Competitive Bid Request. A Competitive Bid Request that does
not conform substantially to the format of Exhibit A-1 may be rejected in the
Agent's sole discretion, and the Agent shall promptly notify the Borrower of
such rejection by telecopy. Each Competitive Bid Request shall refer to this
Agreement and specify (x) whether the Borrowing then being requested is to be a
Eurodollar Borrowing or a Fixed Rate Borrowing, (y) the date of such Borrowing
(which shall be a Business Day) and the aggregate principal amount thereof which
shall be in a minimum principal amount of $10,000,000 and in an integral
multiple of $1,000,000, and (z) the Interest Period with respect thereto (which
may not end after the Maturity Date) and the interest payment date or dates
relating thereto. Promptly after its receipt of a Competitive Bid Request that
is not rejected as aforesaid, the Agent shall invite by telecopy (in the form
set forth in Exhibit A-2 hereto) the Lenders to bid, on the terms and conditions
of this Agreement, to make Competitive Loans pursuant to the Competitive Bid
Request.

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

        (c)      The Agent shall promptly notify the Borrower, by telecopy, of
all the Competitive Bids made, the Competitive Bid Rate and the principal amount
of each Competitive Loan in respect of which a Competitive Bid was made and the
identity of the Lender that made each bid. The Agent shall send a copy of all
Competitive Bids to the Borrower for its records as soon as practicable after
completion of the bidding process set forth in this Section 2.03.

                                       14
<PAGE>   19

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

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

        (f)      A Competitive Bid Request shall not be made within five
Business Days after the date of any previous Competitive Bid Request. No
Competitive Borrowing shall be requested or made hereunder if after giving
effect thereto any of the conditions set forth in Section 2.01 would not be met.

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

                                       15
<PAGE>   20

        (h)    Upon the request of any Lender making a Competitive Loan, the
indebtedness of the Borrower resulting from such Competitive Loan shall be
evidenced by a separate promissory note of the Borrower in substantially the
form of Exhibit A-5 hereto payable to the order of the Lender making such
Competitive Loan.

        (i)    All notices required by this Section 2.03 shall be given in
accordance with Section 8.01.

        SECTION 2.04. Committed Borrowing Procedure. In order to request a
Committed Borrowing, the Borrower shall hand deliver or telecopy to the Agent a
duly completed Committed Borrowing Request in the form of Exhibit A-6 (a) in the
case of a Eurodollar Committed Borrowing, not later than 10:30 a.m., New York
City time, three Business Days before a proposed Borrowing and (b) in the case
of an ABR Borrowing, not later than 10:30 a.m., New York City time, on the day
of a proposed Borrowing. No Fixed Rate Loan shall be requested or made pursuant
to a Committed Borrowing Request. Such notice shall be irrevocable and shall in
each case specify (i) whether the Borrowing then being requested is to be a
Eurodollar Committed Borrowing or an ABR Borrowing; (ii) the date of such
Committed Borrowing (which shall be a Business Day) and the amount thereof; and
(iii) if such Borrowing is to be a Eurodollar Committed Borrowing, the Interest
Period with respect thereto, which shall not end after the Maturity Date. If no
election as to the Type of Committed Borrowing is specified in any such notice,
then the requested Committed Borrowing shall be an ABR Borrowing. If no Interest
Period with respect to any Eurodollar Committed Borrowing is specified in any
such notice, then the Borrower shall be deemed to have selected an Interest
Period of one month's duration. Notwithstanding any other provision of this
Agreement to the contrary, the Borrower shall not be entitled to request any
Committed Borrowing if the Interest Period requested with respect to such
Committed Borrowing would end after the Maturity Date. The Agent shall promptly
advise the Lenders of any notice given pursuant to this Section 2.04 and of each
Lender's portion of the requested Borrowing.

        SECTION 2.05. Conversion and Continuation of Committed Loans. The
Borrower shall have the right at any time upon prior irrevocable notice to the
Agent (i) not later than 10:30 a.m., New York City time, on the day of the
conversion, to convert all or any part of any Eurodollar Committed Borrowing
into an ABR Borrowing, (ii) not later than 10:30 a.m., New York City time, three
Business Days prior to conversion or continuation, to convert any ABR Borrowing
into a Eurodollar Committed Borrowing or to continue any Eurodollar Committed
Borrowing as a Eurodollar Committed Borrowing for an additional Interest Period
and (iv) not later than 10:30 a.m., New York City time, three Business Days
prior to conversion, to convert the Interest Period, with respect to any
Eurodollar Committed Borrowing to another permissible Interest Period, subject
in each case to the following:

        (a)    if less than all the outstanding principal amount of any
    Committed Borrowing shall be converted or continued, the aggregate principal
    amount of the Committed Borrowing converted or continued shall be an
    integral multiple of $1,000,000 and not less than $10,000,000;

        (b)    accrued interest on a Committed Borrowing (or portion thereof)
    being converted shall be paid by the Borrower at the time of conversion;

                                       16
<PAGE>   21

        (c)    if any Eurodollar Committed Borrowing is converted at a time
    other than the end of the Interest Period applicable thereto, the Borrower
    shall pay, upon demand, any amounts due to the Lenders pursuant to Section
    2.15;

        (d)    any portion of a Committed Borrowing maturing or required to be
    repaid in less than one month may not be converted into or continued as a
    Eurodollar Committed Borrowing;

        (e)    any portion of a Eurodollar Committed Borrowing which cannot be
    continued as a Eurodollar Committed Borrowing by reason of clause (d) above
    shall be automatically converted at the end of the Interest Period in effect
    for such Eurodollar Committed Borrowing into an ABR Borrowing; and

        (f)    no Interest Period may be selected for any Eurodollar Committed
    Borrowing that would end later than the Maturity Date.

        Each notice of the Borrower pursuant to this Section 2.05 shall be
irrevocable and shall refer to this Agreement and specify (i) the identity and
amount of the Committed Borrowing that the Borrower requests to be converted or
continued, (ii) whether such Committed Borrowing is to be converted to or
continued as a Eurodollar Committed Borrowing or an ABR Borrowing, (iii) if such
notice requests a conversion, the date of such conversion (which shall be a
Business Day) and (iv) if such Committed Borrowing is to be converted to or
continued as a Eurodollar Committed Borrowing, the Interest Period with respect
thereto. If no Interest Period is specified in any such notice with respect to
any conversion to or continuation as a Eurodollar Committed Borrowing, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. If the Borrower shall not have given notice in accordance with this
Section 2.05 to convert or continue any Committed Borrowing, such Committed
Borrowing shall, at the end of the Interest Period applicable thereto (unless
repaid pursuant to the terms hereof), automatically be converted or continued
into a new Interest Period as an ABR Borrowing.

        SECTION 2.06. Fees. (a) The Borrower agrees to pay to each Lender,
through the Agent, on each March 31, June 30, September 30 and December 31 (with
the first payment being due on September 30, 2000) and on the date on which the
Commitment of such Lender shall be terminated or reduced as provided herein, a
facility fee (a "Facility Fee") equal to the Applicable Percentage per annum in
effect from time to time on the average daily amount of the Commitment of such
Lender, whether used or unused, during the preceding quarter (or other period
commencing on the date of this Agreement, or ending with the Maturity Date or
any date on which the Commitment of such Lender shall be terminated or reduced).
All Facility Fees shall be computed on the basis of the actual number of days
elapsed in a year of 360 days. The Facility Fee due to each Lender shall
commence to accrue on the date of this Agreement, and shall cease to accrue on
the earlier of the Maturity Date and the termination of the Commitment of such
Lender as provided herein.

        (b)    The Borrower agrees to pay the Agent, for its own account, the
administrative and other fees referred to in the Fee Letter (the "Administrative
Fees") at the times and in the amounts agreed upon in the Fee Letter.

                                       17
<PAGE>   22

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

        SECTION 2.07. Repayment of Loans; Evidence of Debt. (a) The Borrower
hereby agrees that the outstanding principal balance of each Committed Loan
shall be payable on the Maturity Date, and that the outstanding principal
balance of each Competitive Loan shall be payable on the last day of the
Interest Period applicable thereto. Each Loan shall bear interest on the
outstanding principal balance thereof as set forth in Section 2.08.

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

        (c)    The Agent shall maintain the Register pursuant to Section
8.04(d), and a subaccount for each Lender, in which Register and accounts (taken
together) shall be recorded (i) the amount of each Loan made hereunder, the Type
of each Loan made and the Interest Period applicable thereto, (ii) the amount of
any principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Agent hereunder from the Borrower and each Lender's share thereof.

        (d)    The entries made in the Register and accounts maintained pursuant
to paragraph (b) and (c) of this Section 2.07 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Lender or the Agent to maintain such account, such Register or
such subaccount, as applicable, or any error therein shall not in any manner
affect the obligation of the Borrower to repay the Loans made to the Borrower by
such Lender in accordance with their terms.

        (e) The Borrower agrees that upon notice by any Lender after the initial
borrowing hereunder to the Borrower (with a copy to the Agent) to the effect
that a promissory note or other evidence of indebtedness is required or
appropriate in order for such Lender to evidence (whether for purposes of
pledge, enforcement or otherwise) the Committed Loans owing to, or to be made
by, such Lender, the Borrower shall promptly, execute and deliver to such
Lender, with a copy to the Agent, a promissory note or notes, in substantially
the form of Exhibit B hereto, payable to the order of such Lender in a principal
amount equal to the Commitment of such Lender.

        SECTION 2.08. Interest on Loans. (a) Subject to the provisions of
Section 2.09, the Loans comprising each Eurodollar Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to (i) in the case of each Eurodollar Committed
Loan, the LIBO Rate for the Interest Period in effect for such Borrowing plus
(x) the Applicable Margin from time to time in effect plus (y) the Applicable
Utilization Fee from time to time in effect and (ii) in the case of each
Eurodollar Competitive

                                       18
<PAGE>   23

Loan, the LIBO Rate for the Interest Period in effect for such Borrowing plus
the Margin offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

        (b)    Subject to the provisions of Section 2.09, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as the case may be, for
periods during which the Alternate Base Rate is determined by reference to the
Base Rate and 360 days for periods during which the Alternate Base Rate is
determined by reference to the Federal Funds Effective Rate) at a rate per annum
equal to the Alternate Base Rate from time to time in effect plus the Applicable
Margin from time to time in effect.

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

        (d)    Interest on each Loan shall be payable on each Interest Payment
Date applicable to such Loan except as otherwise provided in this Agreement. The
applicable LIBO Rate or Alternate Base Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined in good faith
by the Agent, and such determination shall be conclusive absent manifest error.

        (e)    Each Reference Bank agrees to furnish to the Agent timely
information for the purpose of determining each Eurodollar Loan and each LIBO
Rate. If any one or more of the Reference Banks shall not furnish such timely
information to the Agent for the purpose of determining any such interest rate,
the Agent shall determine such interest rate on the basis of timely information
furnished by the remaining Reference Banks. The Agent shall give prompt notice
to the Borrower and the Lenders of the applicable interest rate determined by
the Agent for purposes of Section 2.08(a), (b) or (c), and the rate, if any,
furnished by each Reference Bank for the purpose of determining the interest
rate under Section 2.08(a).

        (f)    If fewer than two Reference Banks furnish timely information to
the Agent for determining the LIBO Rate for any Eurodollar Loan,

        (i)    the Agent shall forthwith notify the Borrower and the Lenders
    that the interest rate cannot be determined for such Eurodollar Loans,

        (ii)   with respect to Eurodollar Loans, each such Loan will
    automatically, on the last day of the then existing Interest Period
    therefor, be prepaid by the Borrower or be automatically converted into a
    Base Rate Loan, and

        (iii)  the obligation of the Lenders to make Eurodollar Loans or to
    convert Base Rate Loans into Eurodollar Loans shall be suspended until the
    Agent shall notify the Borrower and the Lenders that the circumstances
    causing such suspension no longer exist.

        (g)    Upon the occurrence and during the continuance of any Event of
Default under Section 6.01(b) or (c), (i) each Eurodollar Committed Loan will
automatically, on the last

                                       19
<PAGE>   24

day of the then existing Interest Period therefor, be converted into Base Rate
Loans and (ii) the obligation of the Lenders to make, or to convert Advances
into, Eurodollar Committed Loans shall be suspended.

        SECTION 2.09. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, whether by scheduled maturity, notice of prepayment, acceleration
or otherwise, the Borrower shall on demand from time to time from the Agent pay
interest, to the extent permitted by law, on such defaulted amount up to (but
not including) the date of actual payment (after as well as before judgment) at
a rate per annum (computed on the basis of the actual number of days elapsed
over a year of 360 days) equal to the Alternate Base Rate plus 1%.

        SECTION 2.10. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Agent shall have determined in
good faith (i) that dollar deposits in the principal amounts of the Eurodollar
Loans comprising such Borrowing are not generally available in the London
interbank market or (ii) that reasonable means do not exist for ascertaining the
LIBO Rate, the Agent shall, as soon as practicable thereafter, give telecopy
notice of such determination to the Borrower and the Lenders. In the event of
any such determination under clauses (i) or (ii) above, until the Agent shall
have advised the Borrower and the Lenders that the circumstances giving rise to
such notice no longer exist, (x) any request by the Borrower for a Eurodollar
Competitive Borrowing pursuant to Section 2.03 shall be of no force and effect
and shall be denied by the Agent and (y) any request by the Borrower for a
Eurodollar Committed Borrowing pursuant to Section 2.04 shall be deemed to be a
request for an ABR Borrowing. In the event a Lender notifies the Agent that the
rates at which dollar deposits are being offered will not adequately and fairly
reflect the cost to such Lender of making or maintaining its Eurodollar Loan
during such Interest Period, the Agent shall notify the Borrower of such notice
and until the Lender shall have advised the Agent that the circumstances giving
rise to such notice no longer exist, any request by the Borrower for a
Eurodollar Committed Borrowing shall be deemed a request for an ABR Borrowing
for the same Interest Period with respect to such Lender. Each determination by
the Agent hereunder shall be in good faith and conclusive absent manifest error.

        SECTION 2.11. Termination and Reduction of Commitments. (a) The
Commitments shall be automatically terminated on the Maturity Date.

        (b)    Upon at least three Business Days' prior irrevocable telecopy
notice to the Agent, the Borrower may at any time in whole permanently
terminate, or from time to time in part permanently reduce, the Total
Commitment; provided, however, that (i) each partial reduction of the Total
Commitment shall be in an integral multiple of $1,000,000 and in a minimum
principal amount of $10,000,000 and (ii) no such termination or reduction shall
be made which would reduce the Total Commitment to an amount less than the
aggregate outstanding principal amount of the Loans. Once terminated or reduced,
the Total Commitment may not be reinstated.

        (c)    Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments. The
Borrower shall pay

                                       20
<PAGE>   25

to the Agent for the account of the Lenders, on the date of each termination or
reduction of the Commitment, the Facility Fees on the amount of the Commitments
so terminated or reduced accrued through the date of such termination or
reduction.

        SECTION 2.12. Prepayment. (a) The Borrower shall have the right at any
time and from time to time to prepay any Committed Borrowing, in whole or in
part, upon giving telecopy notice (or telephone notice promptly confirmed by
telecopy notice) to the Agent: (i) before 10:00 a.m., New York City time, two
Business Days prior to prepayment, in the case of Eurodollar Loans, and (ii)
before 10:00 a.m., New York City time, on the same Business Day of prepayment,
in the case of ABR Loans; provided, however, that each partial prepayment shall
be in an amount which is an integral multiple of $1,000,000 and not less than
$5,000,000. The Borrower shall not have the right to prepay any Competitive
Borrowing.

        (b)    On the date of any termination or reduction of the Commitments
pursuant to Section 2.11, the Borrower shall pay or prepay so much of the
Committed Borrowings as shall be necessary in order that the aggregate principal
amount of the Competitive Loans and Committed Loans outstanding will not exceed
the Total Commitment, after giving effect to such termination or reduction.

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

        SECTION 2.13. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall result in the imposition, modification or applicability of any
reserve, special deposit or similar requirement against assets of, deposits with
or for the account of or credit extended by any Lender, or shall result in the
imposition on such Lender or the London interbank market any other condition
affecting this Agreement, such Lender's Commitment or any Eurodollar Loan, or
Fixed Rate Loan made by such Lender, and the result of any of the foregoing
shall be to increase the cost to such Lender of making or maintaining any
Eurodollar Loan or Fixed Rate Loan or to reduce the amount of any sum received
or receivable by such Lender hereunder (whether of principal, interest or
otherwise) by an amount deemed by such Lender to be material, then the Borrower
will pay to such Lender upon demand such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.
Notwithstanding the foregoing, no Lender shall be entitled to request
compensation under this paragraph with respect to any Competitive Loan if the
change giving rise to such request was applicable to such Lender at the time of
submission of the Competitive Bid pursuant to which such Competitive Loan shall
have been made.

                                       21
<PAGE>   26

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

        (c)    A certificate of the Lender setting forth such amount or amounts
(including computation of such amount or amounts) as shall be necessary to
compensate the Lender or its holding company as specified in paragraph (a) or
(b) above, as the case may be, shall be delivered to the Borrower and such
amount or amounts may be reviewed by the Borrower. Unless the Borrower disagrees
in good faith with the computation of the amount or amounts in such certificate,
the Borrower shall pay to the Lender, within 10 Business Days after receipt by
the Borrower of such certificate delivered by the Lender, the amount shown as
due on any such certificate. If the Borrower, after receipt of any such
certificate from the Lender, disagrees with the Lender on the computation of the
amount or amounts owed to the Lender pursuant to paragraph (a) or (b) above, the
Lender and the Borrower shall negotiate in good faith to promptly resolve such
disagreement. In either case, however, the Lender shall have a duty to mitigate
the damages that may arise as a consequence of paragraph (a) or (b) above to the
extent that such mitigation will not, in the judgment of the Lender, entail any
cost or disadvantage to the Lender that the Lender is not reimbursed or
compensated for by the Borrower.

        (d)    Failure on the part of any Lender to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to any period shall not constitute a waiver of
such Lender's right to demand compensation with respect to any other period;
provided that if any Lender fails to make such demand within 45 days after it
obtains knowledge of the event giving rise to the demand such Lender shall, with
respect to amounts payable pursuant to this Section 2.13 resulting from such
event, only be entitled to payment under this Section 2.13 for such costs
incurred or reduction in amounts or return on capital from and after the date 45
days prior to the date that such Lender does make such demand. The protection of
this Section shall be available to each Lender regardless of any possible
contention of the invalidity or inapplicability of the law, rule, regulation,
guideline or other change or condition which shall have occurred or been
imposed.

                                       22
<PAGE>   27

        SECTION 2.14. Change in Legality. (a) Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by 30 days' (or
such shorter period as shall be required in order to comply with applicable law)
written notice to the Borrower and to the Agent, such Lender may:

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

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

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

        (b)    For purposes of this Section 2.14, a notice to the Borrower by
any Lender shall be effective as to each Eurodollar Loan, if lawful, on the last
day of the Interest Period currently applicable to such Eurodollar Loan; in all
other cases such notice shall be effective on the date of receipt by the
Borrower.

        SECTION 2.15. Indemnity. The Borrower shall indemnify each Lender
against any out-of-pocket loss or expense which such Lender may sustain or incur
as a consequence of (a) any failure by the Borrower to borrow or to refinance,
convert or continue any Loan hereunder after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03, 2.04 or 2.05, (b) any payment, prepayment or conversion, or an
assignment required under Section 2.20, of a Eurodollar Loan by the Borrower
required by any other provision of this Agreement or otherwise made or deemed
made on a date other than the last day of the Interest Period, if any,
applicable thereto, (c) any default by the Borrower in payment or prepayment of
the principal amount of any Loan or any part thereof or interest accrued
thereon, as and when due and payable (at the due date thereof, whether by
scheduled maturity, acceleration, irrevocable notice of prepayment or otherwise)
or (d) the occurrence of any Event of Default.

        In the case of a Eurodollar Loan, such out-of-pocket loss or expense
shall be limited to an amount equal to the excess, if any, of (i) its cost of
obtaining the funds for the Loan being paid, prepaid, converted or not borrowed,
converted or continued (based on the LIBO Rate applicable thereto) for the
period from the date of such payment, prepayment, conversion or failure to
borrow, convert or continue to the last day of the Interest Period for such Loan
(or, in

                                       23
<PAGE>   28

the case of a failure to borrow, convert or continue, the Interest Period for
such Loan which would have commenced on the date of such failure) over (ii) the
amount of interest that would be realized by the Lender in reemploying the funds
so paid, prepaid, converted or not borrowed, converted or continued for such
period or Interest Period, as the case may be. In the case of an ABR Loan, such
out-of-pocket loss or expense shall be limited to an amount equal to the excess,
if any, of (i) its cost of obtaining the funds for the ABR Loan being paid,
prepaid, converted or not borrowed, converted or continued for the period from
the date of such payment, prepayment, conversion or failure to borrow, convert
or continue to the next Business Day for such ABR Loan over (ii) the amount of
interest that would be realized by the Lender in reemploying the funds so paid,
prepaid, converted or not borrowed, converted or continued until the next
Business Day, as the case may be.

        A certificate of the Lender setting forth such amount or amounts
(including the computation of such amount or amounts) as shall be necessary to
compensate the Lender or its holding company for the out-of-pocket expenses
defined herein shall be delivered to the Borrower and such amount or amounts may
be reviewed by the Borrower. If the Borrower, after receipt of any such
certificate from the Lender, disagrees in good faith with the Lender on the
computation of the amount owed to the Lender pursuant to this Section 2.15, the
Lender and the Borrower shall negotiate in good faith to promptly resolve such
disagreement.

        Each Lender shall have a duty to mitigate the damages to such Lender
that may arise as a consequence of clause (a), (b), (c) or (d) above to the
extent that such mitigation will not, in the judgment of such Lender, entail any
cost or disadvantage to such Lender that such Lender is not reimbursed or
compensated for by the Borrower.

        SECTION 2.16. Pro Rata Treatment. Except as required under Sections
2.10, 2.13, 2.14, 2.15, 2.19 and 2.20, each Committed Borrowing, each payment or
prepayment of principal of any Committed Borrowing, each payment of interest on
the Committed Loans, each payment of the Facility Fees, each reduction of the
Commitments and each refinancing or conversion of any Borrowing with a Committed
Borrowing of any Type, shall be allocated pro rata among the Lenders in
accordance with their respective Commitments (or, if such Commitments shall have
expired or been terminated, in accordance with the respective principal amounts
of their outstanding Committed Loans). Each payment of principal of any
Competitive Borrowing shall be allocated pro rata among the Lenders
participating in such Borrowing in accordance with the respective principal
amounts of their outstanding Competitive Loans comprising such Borrowing. Each
payment of interest on any Competitive Borrowing shall be allocated pro rata
among the Lenders participating in such Borrowing in accordance with the
respective amounts of accrued and unpaid interest on their outstanding
Competitive Loans comprising such Borrowing. For purposes of determining the
available Commitments of the Lenders at any time, each outstanding Competitive
Borrowing shall be deemed to have utilized the Commitments of the Lenders
(including those Lenders which shall not have made Loans as part of such
Competitive Borrowing) pro rata in accordance with such respective Commitments.
Each Lender agrees that in computing such Lender's portion of any Borrowing to
be made hereunder, the Agent may, in its discretion, round each Lender's
percentage of such Borrowing to the next higher or lower whole dollar amount.

                                       24
<PAGE>   29

        SECTION 2.17. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower, or pursuant to a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, obtain
payment (voluntary or involuntary) in respect of any Committed Loan or Loans as
a result of which the unpaid principal portion of the Committed Loans of such
Lender shall be proportionately less than the unpaid principal portion of the
Committed Loans of any other Lender, it shall be deemed simultaneously to have
purchased from such other Lender at face value, and shall promptly pay to such
other Lender the purchase price for, a participation in the Committed Loans of
such other Lender, so that the aggregate unpaid principal amount of the
Committed Loans and participations in the Committed Loans held by each Lender
shall be in the same proportion to the aggregate unpaid principal amount of all
Committed Loans then outstanding as the principal amount of its Committed Loans
prior to such exercise of banker's lien, setoff or counterclaim or other event
was to the principal amount of all Committed Loans outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
however, that, if any such purchase or purchases or adjustments shall be made
pursuant to this Section 2.17 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Committed Loan deemed to have been so purchased may exercise any and all rights
of banker's lien, setoff or counterclaim with respect to any and all moneys
owing by the Borrower to such Lender by reason thereof as fully as if such
Lender had made a Committed Loan directly to the Borrower in the amount of such
participation.

        SECTION 2.18. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder from an account in the United States not later than 12:00
noon, New York City time, on the date when due in dollars to the Agent at its
offices at 399 Park Avenue, New York, NY 10043, in immediately available funds.

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

        SECTION 2.19. Taxes. (a) Any and all payments by the Borrower hereunder
shall be made, in accordance with Section 2.18, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto imposed by the
United States or any political subdivision or taxing authority thereof,
excluding taxes imposed on the Agent's or any Lender's (or any transferee's or
assignee's, including a participation holder's (any such entity a "Transferee"))
net income and franchise taxes imposed on the Agent or any Lender (or
Transferee) by the United States or any political subdivision or taxing
authority thereof (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as "Taxes").
If the

                                       25
<PAGE>   30

Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder to any Lender (or any Transferee) or the Agent, (i) the
sum payable shall be increased by the amount necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.19) such Lender (or Transferee) or the Agent (as the case
may be) shall receive an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxing
authority or other Governmental Authority in accordance with applicable law.

        (b)    In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement imposed by the United States or any political subdivision or taxing
authority thereof (hereinafter referred to as "Other Taxes").

        (c)    The Borrower will indemnify each Lender (or Transferee) and the
Agent for the full amount of Taxes and Other Taxes (including any Taxes or Other
Taxes on amounts payable under this Section 2.19) paid by such Lender (or
Transferee) or the Agent, as the case may be, with respect to the Borrower and
any liability (including penalties, interest and reasonable out-of-pocket
expenses) arising therefrom or with respect thereto (other than any such
liability that results from the gross negligence or willful misconduct of the
Lender (or Transferee) or Agent), whether or not such Taxes or Other Taxes were
correctly or legally asserted by the relevant taxing authority or other
Governmental Authority. Such indemnification shall be made within 30 days after
the date any Lender (or Transferee) or the Agent, as the case may be, makes
written demand therefor. If the Borrower or any Lender (or Transferee) or the
Agent shall determine that Taxes or Other Taxes may not have been correctly or
legally assessed by the relevant taxing authority or other Governmental
Authority, and that a Lender (or Transferee) or the Agent may be entitled to
receive a refund in respect of Taxes or Other Taxes, it shall promptly notify
the other party of the availability of such refund and such Lender (or
Transferee) or the Agent shall, within 60 days after receipt of a request by the
Borrower, apply for such refund at the Borrower's expense. If any Lender (or
Transferee) or the Agent receives a refund or credit or offset against another
tax liability in respect of any Taxes or Other Taxes for which such Lender (or
Transferee) or the Agent has received payment from the Borrower hereunder it
shall promptly repay such refund or credit or offset against another tax
liability (including any interest received by such Lender (or Transferee) or the
Agent from the taxing authority with respect to the refund with respect to such
Taxes or Other Taxes) to the Borrower, net of all out-of-pocket expenses of such
Lender; provided that the Borrower, upon the request of such Lender (or
Transferee) or the Agent, agrees to return such refund or credit or offset
against another tax liability (plus penalties, interest or other charges) to
such Lender (or Transferee) or the Agent in the event such Lender (or
Transferee) or the Agent is required to repay such refund or credit or offset
against another tax liability. For purposes of the preceding sentence, the Agent
or any Lender shall determine in good faith and in its discretion the amount of
any credit or offset against another tax liability and shall be under no
obligation to make available to the Borrower any of its tax returns or any other
information that it deems to be confidential.

        (d)    As soon as practicable after the date of any payment of Taxes or
Other Taxes withheld by the Borrower in respect of any payment to any Lender (or
Transferee) or the

                                       26
<PAGE>   31

Agent, the Borrower will furnish to the Agent, at its address referred to in
Section 8.01, the original or a certified copy of a receipt evidencing payment
thereof.

        (c)    Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.19
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

        (f)    Each Lender (or Transferee) which is organized outside the United
States shall, prior to the due date of the first payment by the Borrower to such
Lender (or Transferee) hereunder, deliver to the Borrower such certificates,
documents or other evidence, as required by the Code or Treasury Regulations
issued pursuant thereto, including Internal Revenue Service Form W-8BEN or Form
W-8ECI and any other certificate or statement of exemption required by Treasury
Regulation Section 1.1441-1(a) or Section 1.1441-6(c) or any subsequent version
thereof, properly completed and duly executed by such Lender (or Transferee)
establishing that such payment is (i) not subject to withholding under the Code
because such payment is effectively connected with the conduct by such Lender
(or Transferee) of a trade or business in the United States or (ii) totally
exempt from United States tax under a provision of an applicable tax treaty.
Each such Lender (or Transferee) that changes its funding office shall promptly
notify the Borrower of such change and, upon written request from the Borrower,
shall deliver any new certificates, documents or other evidence required
pursuant to the preceding sentence prior to the immediately following due date
of any payment by the Borrower hereunder. Unless the Borrower and the Agent have
received forms or other documents satisfactory to them indicating that payments
hereunder are not subject to United States withholding tax, notwithstanding
paragraph (a), the Borrower or the Agent shall withhold taxes from such payments
at the applicable statutory rate in the case of payments to or for any Lender
(or Transferee) organized under the laws of a jurisdiction outside the United
States.

        (g)    The Borrower shall not be required to pay any additional amounts
to any Lender (or Transferee) in respect of Taxes and Other Taxes pursuant to
paragraphs (a), (b) and (c) above if the obligation to pay such additional
amounts would not have arisen but for a failure by such Lender (or Transferee)
to comply with the provisions of paragraph (f) above unless such Lender (or
Transferee) is unable to comply with paragraph (f) because of (i) a change in
applicable law, regulation or official interpretation thereof or (ii) an
amendment, modification or revocation of any applicable tax treaty or a change
in official position regarding the application or interpretation thereof, in
each case after the date hereof (and, in the case of a Transferee, after the
date of assignment or transfer).

        (h)    Any Lender (or Transferee) claiming any additional amounts
payable under this Section 2.19 shall (i) to the extent legally able to do so,
file any certificate or document if such filing would avoid the need for or
reduce the amount of any such additional amounts which may thereafter accrue,
and the Borrower shall not be obligated to pay such additional amounts if, any
Lender (or Transferee) could have filed such certificate or document and failed
to do so; or (ii) consistent with legal and regulatory restrictions, use
reasonable efforts to change the jurisdiction of its applicable lending office
if the making of such change would avoid the need for or reduce the amount of
any additional amounts which may thereafter accrue and would not, in the sole
determination of such Lender (or Transferee), be otherwise disadvantageous to
such Lender (or Transferee).

        SECTION 2.20. Mandatory Assignment; Commitment Termination. In the event
any Lender delivers to the Agent or the Borrower, as appropriate, a certificate
in accordance with Section 2.13(c) or a notice in accordance with Section 2.10
or 2.14 or is a Defaulting Lender, or the Borrower is required to pay any
additional amounts or other payments in accordance with Section 2.19, the
Borrower may, at its own expense, and in its sole discretion (a) require such
Lender to transfer and assign in whole or in part, without recourse (in
accordance with Section 8.04), all or part of its interests, rights and
obligations under this Agreement (other than outstanding Competitive Loans) to
an assignee acceptable to the Agent which shall assume such assigned obligations
(which assignee may be another Lender, if a Lender accepts such assignment);
provided that (i) such assignment shall not conflict with any law, rule or
regulation or order of any court or other Governmental Authority and (ii) the
Borrower or such assignee shall have paid to the assigning Lender in immediately
available funds the principal of and interest accrued to the date of such
payment on the Loans made by it hereunder and all other amounts owed to it
hereunder or (b) terminate the Commitment of such Lender and prepay all
outstanding Loans (other than Competitive Loans) of such Lender; provided that
(x) such termination of the Commitment of such Lender and prepayment of Loans
does not conflict with any law, rule or regulation or order of any court or
Governmental Authority, (y) the Borrower shall have paid to such Lender in
immediately available funds the principal of and interest accrued to the date of
such payment on the Loans (other than Competitive Loans) made by it hereunder
and all other amounts owed to it hereunder and (z) the Borrower shall have paid
to the Agent a processing and recordation fee of $3,500 if such assignee is not
an existing Lender.

        SECTION 2.21. Expansion of Commitments. The Borrower may from time to
time, and notwithstanding any prior reductions in the Total Commitment by the
Borrower, by notice to the Agent (which shall promptly deliver a copy to each of
the Lenders), request that the Total Commitment be increased by an amount that
is not less than $50,000,000 and will not result in the Total Commitment under
this Agreement exceeding $1,100,000,000. Each such notice shall set forth the
requested amount of the increase in the Total Commitment and the date on which
such increase is to become effective (which shall be not fewer than 20 days
after the date of such notice), and shall offer each Lender the opportunity to
increase its Commitment by its ratable share, based on the amounts of the
Lenders' Commitments, of the requested increase in the Total Commitment. Each
Lender shall, by notice to the Borrower and the Agent given not more than 10
Business Days after the date of the Borrower's notice, either agree to increase
its Commitment by all or a portion of the offered amount or decline to increase
its Commitment (and any Lender that does not deliver such a notice within such
period of 10 Business Days shall be deemed to have declined to increase its
Commitment). In the event that, on the 10th Business Day after the Borrower
shall have delivered a notice pursuant to the first sentence of this paragraph,
the Lenders shall have agreed pursuant to the preceding sentence to increase
their Commitments by an aggregate amount less than the increase in the Total
Commitment requested by the Borrower, the Borrower shall have the right to
arrange for one or more banks or other financial institutions (any such assignee
Lender, bank or other financial institution being called an "Augmenting
Lender"), which may include any Lender, to extend Commitments or increase their
existing Commitments in an aggregate amount equal to all or part of the
unsubscribed amount, provided that each Augmenting Lender, if not already a
Lender hereunder, shall be subject to the approval of the Borrower and the Agent
(which approval shall not be unreasonably withheld), the commitment of each such
Augmenting Lender, if not already a Lender hereunder, shall not be less than
$25,000,000, and such Augmenting Lender shall execute all such

                                       28
<PAGE>   33

documentation as the Agent shall specify to evidence its status as a Lender
hereunder. If (and only if) Lenders (including Augmenting Lenders) shall have
agreed to increase their Commitments or to extend new Commitments in an
aggregate amount not less than $50,000,000, such increases and such new
Commitments shall become effective on the date specified in the notice delivered
by the Borrower pursuant to the first sentence of this paragraph, and shall be
deemed added to the Commitments set forth in Schedule 2.01 hereof.
Notwithstanding the foregoing, no increase in the Total Commitment (or in the
Commitment of any Lender) shall become effective under this paragraph unless, on
the date of such increase, the conditions set forth in paragraphs (b) and (c) of
Section 4.01 shall be satisfied (with all references in such paragraphs to a
Borrowing being deemed to be references to such increase) and the Agent shall
have received a certificate to that effect dated such date and executed by a
Responsible Officer of the Borrower.

                                  ARTICLE VII

                                    The Agent

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

        Neither the Agent nor any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them
except for its or his own gross negligence or willful misconduct, or be
responsible for any statement, warranty or representation herein or the contents
of any document delivered in connection herewith, or be required to ascertain or
to make any inquiry concerning the performance or observance by the Borrower of
any of the terms, conditions, covenants or agreements contained in this
Agreement. The Agent shall not be responsible to the Lenders for the due
execution, genuineness, validity, enforceability or effectiveness of this
Agreement or other instruments or agreements. The Agent may deem and treat the
Lender which makes any Loan as the holder of the indebtedness resulting
therefrom for all purposes hereof until it shall have received notice from such
Lender, given as provided herein, of the transfer thereof. The Agent shall in
all cases be fully protected in acting, or refraining from acting, in accordance
with written instructions signed by the Required Lenders and, except as
otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders. The Agent shall,
in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or

                                       39
<PAGE>   44

persons. Neither the Agent nor any of its directors, officers, employees or
agents shall have any responsibility to the Borrower on account of the failure
of or delay in performance or breach by any Lender of any of its obligations
hereunder or to any Lender on account of the failure of or delay in performance
or breach by any other Lender or the Borrower of any of their respective
obligations hereunder or in connection herewith. The Agent may execute any and
all duties hereunder by or through agents or employees and shall be entitled to
rely upon the advice of legal counsel selected by it with respect to all matters
arising hereunder and shall not be liable for any action taken or suffered in
good faith by it in accordance with the advice of such counsel.

        The Lenders hereby acknowledge that the Agent shall be under no duty to
take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

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

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

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

                                       40
<PAGE>   45

gross negligence or willful misconduct of the Agent or any of its directors,
officers, employees or agents.

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

        Each Lender hereby acknowledges that none of the Lead Arranger, the
Co-Syndication Agents, the Co-Arrangers or any agent (other than the Agent)
designated on the signature pages hereof has any liability hereunder other than
in its capacity as a Lender.

        (b)    Each Lender may assign to one or more assignees all or a portion
of its interests, rights and obligations under this Agreement (including all or
a portion of its Commitment and the Loans at the time owing to it); provided,
however, that (i) the Borrower must give its prior written consent to such

        (c)    By executing and delivering an Assignment and Acceptance, the

except as set forth in (i) above, such assigning Lender makes no representation

appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (vi) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto; and

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

the Register.

        (f)    Each Lender may, without the consent of the Borrower or the
Agent, sell participations to one or more banks or other entities in all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans owing to it); provided, however, that
(i) such Lender's obligations under this Agreement shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) each participating bank or other entity
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.13, 2.15 and 2.19 to the same extent as if it was the selling Lender,
except that all claims and petitions for payment and payments made pursuant to
such Sections shall be made through such selling Lender, and (iv) the Borrower,
the Agent and the other Lenders shall continue to deal solely and directly with
such selling Lender in connection with such Lender's rights and obligations
under this Agreement, and such Lender shall retain the sole right (and
participating banks or other entities shall have no right) to enforce the
obligations of the Borrower relating to the Loans and to approve any amendment,
modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the
Loans, or extending any scheduled principal payment date or date fixed for the
payment of interest on the Loans).

        Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure, each
such assignee or participant or proposed assignee or participant shall execute
an agreement whereby such assignee or participant shall agree to be bound by the
confidentiality restrictions included in the Information Memorandum dated August
11, 2000 used by the Agent in connection with the syndication of the
Commitments.

        (g)    and shall agree (subject to customary exceptions) to preserve the
confidentiality of any such confidential information relating to the Borrower.

        (h)    Except in accordance with Section 8.13, the Borrower shall not
assign or delegate any of its respective rights and duties hereunder without the
prior written consent of all Lenders and any attempted assignment without such
consent shall be void.

        (i)    Any Lender may at any time pledge all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
pledge shall release any Lender from its obligations hereunder or substitute any
such Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, the Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes in the form of Exhibit A-5 or B hereto, as applicable, evidencing
the Loans made to the Borrower by the assigning Lender hereunder.

in connection with the Loans made hereunder, including the fees and
disbursements of counsel for the Agent or, in the case of enforcement or
protection, Lenders.

        (b)    The Borrower agrees to indemnify the Agent, the Lenders,
Affiliates, and their respective directors, officers, employees and agents (each
such person being called an "Indemnitee") against, and to hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related
expenses, including reasonable counsel fees and expenses, incurred by or
asserted against any Indemnitee arising out of (i) the execution or delivery of
this Agreement or any agreement or instrument contemplated thereby, the
performance by the parties thereto of their respective obligations thereunder or
the consummation of the transactions contemplated thereby, (ii) the use of the
proceeds of the Loans or (iii) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Indemnitee. Notwithstanding anything to the contrary stated
in this subsection (b), upon Distribution, the Subsequent Borrower hereby,
assumes all obligations of the Initial Borrower to indemnify the Indemnitees
under this Agreement and the Initial Borrower shall be released from all such
obligations.

        (c)    The provisions of this Section 8.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any investigation made by or on behalf of the
Agent or any Lender. All amounts due under this Section 8.05 shall be payable on
written demand therefor.

        SECTION 8.06. Right of Setoff. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request specified
by Section 6.01 to authorize the Agent to declare the Loans due and payable
pursuant to the provisions of Section 6.01, each Lender and each of its
Affiliates is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender or such Affiliate to or for
the credit or the account of the Borrower against any and all of the obligations
of the Borrower now or hereafter existing under this Agreement, whether or not
such Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. Each Lender agrees promptly to notify the Borrower
after any such set off and application, provided that the failure to give such
notice shall not affect the validity of such setoff and application. The rights
of each Lender and its Affiliates under this Section are in addition to other
rights and remedies (including, without limitation, other rights of setoff) that
such Lender and its Affiliates may have.

        SECTION 8.07. Applicable Law. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

        SECTION 8.08. Waivers; Amendment. (a) No failure or delay of the Agent
or any Lender in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Agent and the Lenders
hereunder are cumulative and are not exclusive of any rights or remedies which
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) below, and then
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given. No notice or demand on the Borrower in any case
shall entitle the Borrower to any other or further notice or demand in similar
or other circumstances.

        (b)    Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior written
consent of each Lender affected thereby, (ii) increase the Commitment or
decrease the Facility Fee of any Lender without the prior written consent of
such Lender, or (iii) amend or modify the provisions of Section 2.16 or Section
8.04(h), the provisions of this Section or the definition of the "Required
Lenders," without the prior written consent of each Lender; provided further,
however, that no such agreement shall amend, modify or otherwise affect the
rights or duties of the Agent hereunder without the prior written consent of the
Agent. Each Lender shall be bound by any waiver, amendment or modification
authorized by this Section and any consent by any Lender pursuant to this
Section shall bind any assignee of its rights and interests hereunder.

        SECTION 8.09. Entire Agreement. This Agreement and the Fee Letter
constitute the entire contract among the parties relative to the subject matter
hereof. Any previous agreement among the parties with respect to the subject
matter hereof is superseded by this Agreement and the Fee Letter. Nothing in
this Agreement or the Fee Letter expressed or implied, is intended to confer
upon any party other than the parties hereto any rights, remedies, obligations
or liabilities under or by reason of this Agreement or the Fee Letter.

        SECTION 8.10. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

        SECTION 8.11. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 8.03.

        SECTION 8.12. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

        SECTION 8.13. Assignment, Delegation and Assumption. Upon the
Distribution, the rights and obligations of the Initial Borrower under this
Agreement will automatically, and without further act of the parties hereto, be
assigned and delegated to the Subsequent Borrower and the Subsequent Borrower
will automatically assume all such rights and obligations, including the
obligation to pay the principal of and all interest on any outstanding Loans,
all Fees and all other amounts from time to time owing hereunder, whether such
Loans shall have been made or such interest, fees or other amounts shall have
accrued prior to or after the date of such assignment, delegation and
assumption, such assignment, delegation and assumption to be effective as of the
date of the Distribution. At the time of the Distribution the Initial Borrower
will be released from all obligations under this Agreement and on any Loans and
from and after such time the Subsequent Borrower will be the "Borrower" and sole
obligor hereunder.

respective authorized officers as of the day and year first above written.
