                  COMPETITIVE ADVANCE AND REVOLVING CREDIT FACILITY AGREEMENT
                  (the "Agreement") dated as of March 2, 2001, among
                  PERKINELMER, INC., a Massachusetts corporation (the
                  "Company"), the Borrowing Subsidiaries (as such term is
                  defined herein; together with the Company, the "Borrowers"),
                  the lenders listed in Schedule 2.01 (the "Lenders") and THE
                  CHASE MANHATTAN BANK, a New York banking corporation, as
                  administrative agent for the Lenders (in such capacity, the
                  "Administrative Agent").

                  The Lenders have been requested to extend credit to the
Borrowers 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
Termination Date a principal amount not in excess of $300,000,000 at any time
outstanding. The Lenders have also been requested to provide a procedure
pursuant to which the Borrowers may invite the Lenders to bid on an uncommitted
basis on short-term borrowings by the Borrowers. The proceeds of all such
borrowings are to be used by the Borrowers for general corporate purposes,
including to finance acquisitions and to provide working capital for use in the
ordinary course of their businesses. The Lenders are willing to extend such
credit on the terms and subject to the conditions herein set forth. Capitalized
terms used but not defined herein shall have the meanings assigned to such terms
in Article I.

                  This Agreement amends and restates the $300,000,000 Amended
and Restated Competitive Advance and Revolving Credit Facility Agreement dated
as of March 3, 2000, among the Company, the Borrowing Subsidiaries, the lenders
party thereto and the Administrative Agent (the "Existing Credit Agreement").

                  Accordingly, the parties hereto 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 Standby Loan bearing interest at a
rate determined by reference to the Alternate Base Rate in accordance with the
provisions of Article II.

                  "Administrative Questionnaire" shall mean an Administrative
Questionnaire in the form of Exhibit B hereto.
<PAGE>   7
                                                                               2

                  "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.

                  "Alternate Base Rate" shall mean, for any day, a rate per
annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to the
greater of (a) the Prime 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, "Prime
Rate" shall mean the rate of interest per annum publicly announced from time to
time by the Administrative Agent as its prime rate in effect at its principal
office in New York City; each change in the Prime Rate shall be effective on the
date such change is publicly announced as effective. "Federal Funds Effective
Rate" shall mean, for any day, the weighted average of the rates on overnight
Federal funds transactions with members of the Federal Reserve System arranged
by Federal funds brokers, as released on the next succeeding Business Day by the
Federal Reserve Bank of New York, or, if such rate is not so released for any
day which is a Business Day, the arithmetic average (rounded upwards to the next
1/100th of 1%), as determined by the Administrative Agent, of the quotations for
the day of such transactions received by the Administrative Agent from three
Federal funds brokers of recognized standing selected by it. If for any reason
the Administrative 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
Administrative 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 Prime Rate or the Federal Funds Effective Rate shall
be effective on the effective date of such change in the Prime Rate or the
Federal Funds Effective Rate, respectively.

                  "Applicable Percentage" shall mean on any date, with respect
to Eurodollar Standby Loans or with respect to the Facility Fee, as the case may
be, the applicable percentage set forth below under the caption "Eurodollar
Spread" or "Facility Fee Percentage", as the case may be, based upon the Ratings
in effect on such date:

For purposes of the foregoing, (i) if the Ratings shall fall within different
Categories, the Applicable Percentage shall be based upon the higher of the two
Categories; provided, however, that if the difference in the Ratings is greater
than one Category, the Applicable Percentage will be based on the Category which
is one Category below the higher Rating; (ii) if no Ratings exist, the
Applicable Percentage shall be based upon Category 7; and (iii) if any Rating
shall be changed (other than as a result of a change in the rating system of
Moody's or S&P), such change shall be effective as of the date on which it is
first announced by the rating agency making such change. Each such change in the
Applicable Percentage shall apply during the period commencing on the effective
date of such change and ending on the date immediately preceding the effective
date of the next such change. If the rating system of Moody's or S&P shall
change, or if either such rating agency shall cease to be in the business of
rating corporate debt obligations, the parties hereto shall negotiate in good
faith to amend the references to specific ratings in this definition to reflect
such changed rating system or the non-availability of ratings from such rating

any Loan required to be made by such other Lender). Each Competitive Loan shall
be made in accordance with the procedures set forth in Section 2.03. The Standby
Loans or Competitive Loans comprising any Borrowing shall be in an aggregate
principal amount which is an integral multiple of $1,000,000 and not less than
$5,000,000 (or an aggregate principal amount equal to the remaining balance of
the available Commitments).

                  (b) Each Competitive Borrowing shall be comprised entirely of
Eurodollar Competitive Loans or Fixed Rate Loans, and each Standby Borrowing
shall be comprised entirely of Eurodollar Standby Loans or ABR Loans, as any
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 (i)
any exercise of such option shall not affect the obligation of such Borrower to
repay such Loan in accordance with the terms of this Agreement and (ii) the
Borrowers shall not be liable for increased costs under Section 2.13 or 2.14 to
the extent that (A) such costs could be avoided by the use of a different branch
or Affiliate to make Eurodollar Loans and (B) such use would not, in the
judgment of such Lender, entail any expense for which such Lender shall not be
indemnified hereunder. Borrowings of more than one Type may be outstanding at
the same time; provided, however, that no Borrowing shall be requested which, if
made, would result in an aggregate of more than 10 separate Standby Borrowings
comprised of Eurodollar Loans being outstanding hereunder at any one time. For
purposes of the foregoing, Borrowings having different Interest Periods,
regardless of whether they commence on the same date, shall be considered
separate Borrowings.

                  (c) Subject to Section 2.02(d), each Lender shall make each
Loan to be made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Administrative Agent in New York, New York,
not later than 12:00 noon, New York City time, and the Administrative Agent
shall by 3:00 p.m., New York City time, credit the amounts so received to the
general deposit account of the applicable Borrower with the Administrative Agent
or, if a Borrowing shall not occur on such date because any condition precedent
herein specified shall not have been met, return the amounts so received to the
respective Lenders. Competitive Loans shall be made by the Lender or Lenders
whose Competitive Bids therefor are accepted pursuant to
<PAGE>   18
                                                                              13

Section 2.03 in the amounts so accepted. Standby Loans shall be made by the
Lenders pro rata in accordance with Section 2.16. Unless the Administrative
Agent shall have received notice from a Lender prior to the date of any
Borrowing that such Lender will not make available to the Administrative Agent
such Lender's portion of such Borrowing, the Administrative Agent may assume
that such Lender has made such portion available to the Administrative Agent on
the date of such Borrowing in accordance with this paragraph (c) and the
Administrative Agent may, in reliance upon such assumption, make available to
the applicable Borrower on such date a corresponding amount. If and to the
extent that such Lender shall not have made such portion available to the
Administrative Agent, such Lender and the applicable Borrower severally agree to
repay to the Administrative Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to such Borrower until the date such amount is repaid to the
Administrative Agent at (i) in the case of such Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (ii) in the
case of such Lender, the Federal Funds Effective Rate. If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement.

                  (d) Any Borrower may refinance all or any part of any
Borrowing with a Borrowing of the same or a different Type made pursuant to
Section 2.03 or Section 2.04, subject to the conditions and limitations set
forth herein and elsewhere in this Agreement, including refinancings of
Competitive Borrowings with Standby Borrowings and Standby Borrowings with
Competitive Borrowings. Any Borrowing or part thereof so refinanced shall be
deemed to be repaid in accordance with Section 2.07 with the proceeds of a new
Borrowing hereunder and the proceeds of the new Borrowing, to the extent they do
not exceed the principal amount of the Borrowing being refinanced, shall not be
paid by the Lenders to the Administrative Agent or by the Administrative Agent
to the applicable Borrower pursuant to Section 2.02(c); provided, however, that
(i) if the principal amount extended by a Lender in a refinancing is greater
than the principal amount extended by such Lender in the Borrowing being
refinanced, then such Lender shall pay such difference to the Administrative
Agent for distribution to the Lender described in (ii) below, (ii) if the
principal amount extended by a Lender in the Borrowing being refinanced is
greater than the principal amount being extended by such Lender in the
refinancing, the Administrative Agent shall return the difference to such Lender
out of amounts received pursuant to (i) above and (iii) to the extent any Lender
fails to pay the Agent amounts due from it pursuant to (i) above, any Loan or
portion thereof being refinanced with such amounts shall not be deemed repaid in
accordance with Section 2.07 and shall be payable by the Company.

                  SECTION 2.03. Competitive Bid Procedure. (a) In order to
request Competitive Bids, a Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Competitive Bid Request in the form of
Exhibit A-1 hereto, to be received by the Administrative 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 Administrative Agent's sole discretion, and the Administrative
Agent shall promptly notify the applicable Borrower of such rejection by
telecopy.
<PAGE>   19
                                                                              14

Each Competitive Bid Request shall refer to this Agreement and specify whether
the Borrowing then being requested is to be a Eurodollar Borrowing or a Fixed
Rate Borrowing, the date of such Borrowing (which shall be a Business Day), the
aggregate principal amount thereof, which shall be in a minimum principal amount
of $5,000,000 and in an integral multiple of $1,000,000, and the Interest Period
with respect thereto (which may not end after the Termination Date). Promptly
after its receipt of a Competitive Bid Request that is not rejected as
aforesaid, the Administrative 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.

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

                  (c) The Administrative Agent shall promptly notify the
applicable 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 Administrative Agent shall send a copy of all Competitive
Bids to such Borrower for its records as soon as practicable after completion of
the bidding process set forth in this Section 2.03.

                  (d) The applicable 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. Such Borrower
shall notify the Administrative 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

                                                                              15

time, on the day of a proposed Competitive Borrowing; provided, however, that
(i) the failure of such Borrower to give such notice shall be deemed to be a
rejection of all the bids referred to in paragraph (c) above, (ii) such 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 such Borrower shall not
exceed the principal amount specified in the Competitive Bid Request, (iv) if
such 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 to exceed the amount specified in the Competitive Bid Request, then
such 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 applicable Borrower. A notice given pursuant to this paragraph (d) shall be
irrevocable.

                  (e) The Administrative 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, and each
successful bidder will thereupon become bound, subject to the other applicable
conditions hereof, to make the Competitive Loan or Loans 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.

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

                  (h) All notices required by this Section 2.03 shall be given
in accordance with Section 9.01.

                  SECTION 2.04. Standby Borrowing Procedure. In order to request
a Standby Borrowing, a Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Standby Borrowing Request in the form of
Exhibit A-5 (a) in the case of a Eurodollar Standby Borrowing, not later than
10:30 a.m., New York City time, three Business Days before such Borrowing, and
(b) in the case of an ABR Borrowing, not later than 10:30 a.m., New York
<PAGE>   21
                                                                              16

City time, on the day of such Borrowing. No Fixed Rate Loan shall be requested
or made pursuant to a Standby Borrowing Request. Such notice shall be
irrevocable and shall in each case specify (i) whether the Borrowing then being
requested is to be a Eurodollar Standby Borrowing or an ABR Borrowing; (ii) the
date of such Standby Borrowing (which shall be a Business Day) and the amount
thereof; and (iii) if such Borrowing is to be a Eurodollar Standby Borrowing,
the Interest Period with respect thereto, which shall not end after the
Termination Date. If no election as to the Type of Standby Borrowing is
specified in any such notice, then the requested Standby Borrowing shall be an
ABR Borrowing. If no Interest Period with respect to any Eurodollar Standby
Borrowing is specified in any such notice, then the Borrower shall be deemed to
have selected an Interest Period of one month's duration. The Administrative
Agent shall promptly advise the Lenders of any notice given pursuant to this
Section 2.04 and of each Lender's portion of the requested Borrowing.

                  SECTION 2.05. Facility Fees. (a) The Company agrees to pay to
each Lender, through the Administrative Agent, on each March 31, June 30,
September 30 and December 31 (with the first payment being due on March 31,
2001), on the Termination Date, on the Maturity Date and on the date on which
the Commitment of such Lender shall be terminated as provided herein, a facility
fee (a "Facility Fee"), at a rate per annum equal to the Applicable Percentage
from time to time in effect (i) on the average daily amount of the Commitment of
such Lender, whether used or unused, on or prior to the Termination Date, and
(ii) on the daily average amount of the outstanding Loans of such Lender after
the Termination Date, in each case during the preceding quarter (or other period
commencing on the date of this Agreement, or ending with the Termination Date or
the Maturity Date or the date on which the Commitment of such Lender shall be
terminated). All Facility Fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days. The Facility Fee due to each
Lender shall commence to accrue on the date of this Agreement and shall cease to
accrue on the earlier of the Maturity Date and the date on which the Commitment
of such Lender shall have been terminated and the Loans of such Lender shall
have been repaid.

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

                  SECTION 2.06. Conversion and Continuation of Standby
Borrowings. The applicable Borrower shall have the right, upon prior irrevocable
notice to the Administrative Agent, (a) not later than 11:00 a.m., New York City
time, one Business Day prior to conversion, to convert any Eurodollar Standby
Borrowing into an ABR Borrowing, (b) not later than 11:00 a.m., New York City
time, three Business Days prior to conversion or continuation, to convert any
ABR Borrowing into a Eurodollar Standby Borrowing or to continue any Eurodollar
Standby Borrowing as a Eurodollar Standby Borrowing for an additional Interest
Period, and (c) not later than 11:00 a.m., New York City time, three Business
Days prior to conversion, to convert the Interest
<PAGE>   22
                                                                              17

Period with respect to any Eurodollar Standby Borrowing to another permissible
Interest Period subject in each case to the following:

                  (i) each conversion or continuation shall be made pro rata
         among the Lenders in accordance with the respective principal amounts
         of the Loans comprising the converted or continued Standby Borrowing;

                  (ii) if less than all the outstanding principal amount of any
         Standby Borrowing shall be converted or continued, the aggregate
         principal amount of such Standby Borrowing converted or continued shall
         be an integral multiple of $1,000,000 and not less than $5,000,000;

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

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

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

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

                  Each notice pursuant to this Section 2.06 shall be by hand
delivery or telecopier and irrevocable and shall refer to this Agreement and
specify (A) the identity and amount of the Standby Borrowing that the Borrower
requests be converted or continued, (B) whether such Standby Borrowing is to be
converted to or continued as a Eurodollar Standby Borrowing or an ABR Borrowing,
(C) if such notice requests a conversion, the date of such conversion (which
shall be a Business Day) and (D) if such Standby Borrowing is to be converted to
or continued as a Eurodollar Standby 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 Standby Borrowing, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. The Administrative Agent shall advise the other Lenders of any notice
given pursuant to this Section 2.06 and of each Lender's portion of any
converted or continued Standby Borrowing. If, with respect to any Interest
Period ending on or after the Termination Date, the applicable Borrower shall
not have given notice in accordance with this Section 2.06 to continue any
Standby Borrowing into a subsequent Interest Period (and shall not otherwise
have given notice in accordance with this Section 2.06 to convert such Standby
Borrowing), such Standby Borrowing shall, at the end of such Interest Period
(unless repaid pursuant to the terms hereof), automatically be continued into
such subsequent Interest Period as an ABR Borrowing.

                  SECTION 2.07 Repayment of Loans; Evidence of Debt. (a) Each
Borrower hereby agrees that the outstanding principal balance of each Standby
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 and on the Termination Date. 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 to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.

                  (c) The Administrative Agent shall maintain accounts in which
it will record (i) the amount of each 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 each
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder from each Borrower and each Lender's share
thereof.

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

                  SECTION 2.08. Interest on Loans. (a) Subject to the provisions
of Section 2.09, the Loans comprising each Eurodollar Borrowing shall bear
interest (computed on the basis of the actual number of days elapsed over a year
of 360 days) at a rate per annum equal to (i) in the case of each Eurodollar
Standby Loan, the LIBO Rate for the Interest Period in effect for such Borrowing
plus the Applicable Percentage from time to time in effect plus an additional
 .125% per annum on any day on which (A) the sum of (1) the outstanding aggregate
principal amount of all Standby Loans made by all Lenders plus (2) the
outstanding aggregate principal amount of all Competitive Loans made by all
Lenders exceeds (B) 33% of the Total Commitment 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 applicable 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 Prime Rate and 360 days for other periods) at a rate per annum equal to
the Alternate Base Rate.

                  (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
<PAGE>   24
                                                                              19

year of 360 days) equal to the fixed rate of interest offered by the Lender
making such Loan and accepted by the Borrower pursuant to Section 2.03.

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

                  SECTION 2.09. Default Interest. If a 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, such Borrower shall owe interest, payable on demand,
to the extent permitted by law, on such defaulted amount up to (but not
including) the date of actual payment (after as well as before judgment) at a
rate per annum (computed as provided in Section 2.08(b)) equal to the Alternate
Base Rate plus 2%.

                  SECTION 2.10. Alternate Rate of Interest. (a) In the event,
and on each occasion, that on the day two Business Days prior to the
commencement of any Interest Period for a Eurodollar Borrowing the
Administrative Agent shall have determined (i) that dollar deposits in the
principal amounts of the Eurodollar Loans comprising such Borrowing are not
generally available in the London interbank market or (ii) that reasonable means
do not exist for ascertaining the LIBO Rate, the Administrative Agent shall, as
soon as practicable thereafter, give telecopy notice of such determination to
the Borrowers and the Lenders. In the event of any such determination under
clauses (i) or (ii) above, until the Administrative Agent shall have advised the
Borrowers and the Lenders that the circumstances giving rise to such notice no
longer exist, (x) any request by a Borrower for a Eurodollar Competitive
Borrowing pursuant to Section 2.03 shall be of no force and effect and shall be
denied by the Administrative Agent and (y) any request by a Borrower for a
Eurodollar Standby Borrowing pursuant to Section 2.04 shall be deemed to be a
request for an ABR Borrowing.

                  (b) In the event a Lender notifies the Administrative 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 Administrative Agent shall
notify the applicable Borrower of such notice and until the Lender shall have
advised the Administrative Agent that the circumstances giving rise to such
notice no longer exist, any request by such Borrower for a Eurodollar Standby
Borrowing shall be deemed a request for an ABR Borrowing for the same Interest
Period with respect to such Lender.

                  (c) Each determination by the Administrative Agent hereunder
shall be made in good faith and shall be conclusive absent manifest error.

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

                  (b) Upon at least three Business Days' prior irrevocable
telecopy notice to the Administrative Agent, the Company may at any time in
whole permanently terminate, or from time
<PAGE>   25
                                                                              20

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 $5,000,000 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.

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

                  SECTION 2.12. Prepayment. (a) Each Borrower shall have the
right at any time and from time to time to prepay any Standby Borrowing, in
whole or in part, upon giving telecopy notice (or telephone notice promptly
confirmed by telecopy) to the Administrative Agent: (i) before 10:00 a.m., New
York City time, three Business Days prior to prepayment, in the case of
Eurodollar Loans, and (ii) before 10:00 a.m., New York City time, one Business
Day prior to prepayment, in the case of ABR Loans; provided, however, that each
partial prepayment shall be in an amount which is an integral multiple of
$1,000,000 and not less than $5,000,000. No prepayment may be made in respect of
any Competitive Borrowing.

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

                  (c) Each notice of prepayment shall specify the prepayment
date and the principal amount of each Borrowing (or portion thereof) to be
prepaid, shall be irrevocable and shall commit the applicable 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 any Lender or the London interbank market of 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 with
<PAGE>   26
                                                                              21

respect to any Eurodollar Loan or Fixed Rate Loan hereunder (whether of
principal, interest or otherwise) by an amount deemed by such Lender to be
material, then such additional amount or amounts as will compensate such Lender
for such additional costs or reduction will be paid by the Borrowers to such
Lender upon demand. Notwithstanding the foregoing, no Lender shall be entitled
to request compensation under this paragraph with respect to any Competitive
Loan if the change giving rise to such request was applicable to such Lender at
the time of submission of the Competitive Bid pursuant to which such Competitive
Loan was made.

                  (b) If any Lender shall have determined that the adoption
after the date hereof of any law, rule, regulation or guideline arising out of
the July 1988 report of the Basle Committee on Banking Regulations and
Supervisory Practices entitled "International Convergence of Capital Measurement
and Capital Standards," or the adoption after the date hereof of any other law,
rule, regulation or guideline regarding capital adequacy, or any change in any
of the foregoing or in the interpretation or administration of any of the
foregoing by any Governmental Authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by any
Lender or any entity controlling a Lender (or any lending office of such Lender
or entity controlling such Lender) 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 the capital of an entity controlling
such Lender) 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 could have achieved but for such adoption, change or compliance (taking
into consideration such Lender's policies with respect to capital adequacy) by
an amount deemed by such Lender to be material, then from time to time such
additional amount or amounts as will compensate such Lender for such reduction
will be paid by the Borrowers to such Lender.

                  (c) A certificate of each Lender setting forth such amount or
amounts as shall be necessary to compensate such Lender as specified in
paragraph (a) or (b) above, as the case may be, shall be delivered to the
Company promptly by such Lender upon becoming aware of any costs pursuant to
paragraphs (a) or (b) above and shall be conclusive absent manifest error. The
Company shall pay each Lender the amount shown as due on any such certificate
delivered by it within 10 days after its receipt of the same.

                  (d) Failure on the part of any Lender to demand compensation
for any increased costs or reduction in amounts received or receivable or
reduction in return on capital with respect to any period shall not constitute a
waiver of such Lender's right to demand compensation with respect to such period
or any other period. 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. No Lender shall be entitled
to compensation under this Section 2.13 for any costs incurred or reduction
suffered with respect to any date unless such Lender shall have notified the
Company that it will demand compensation for such costs or reductions not more
than 90 days after the later of (i) such date and (ii) the date on which such
Lender shall have become aware of such costs or reductions. Notwithstanding any
other provision of this Section 2.13, no Lender shall demand compensation for
any increased cost or reduction referred to above if it shall not at the time be
the
<PAGE>   27
                                                                              22

general policy or practice of such Lender to demand such compensation in similar
circumstances under comparable provisions of other credit agreements, if any.

                  SECTION 2.14. Change in Legality. (a) Notwithstanding any
other provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the Company and to the Administrative 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 for a Eurodollar Standby 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 by any Lender
shall be effective as to each Eurodollar Loan, if lawful, on the last day of the
Interest Period currently applicable to such Eurodollar Loan; in all other cases
such notice shall be effective on the date of receipt.

                  SECTION 2.15. Indemnity. The Borrowers 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 to borrow or to refinance any Loan
hereunder after irrevocable notice of such borrowing or refinancing has been
given pursuant to Section 2.03 or 2.04, (b) any payment, prepayment or
conversion, or assignment required under Section 2.19, of a Eurodollar Loan
required by any other provision of this Agreement (other than Section 2.14) 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 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, including, in each such case, any
loss or reasonable expense sustained or incurred or to be sustained or incurred
in liquidating or employing deposits from third parties acquired to effect or
maintain such Loan or any part thereof as a Eurodollar Loan or a Fixed Rate
Loan. Such loss or reasonable expense shall include an amount equal to the
excess, if any, as reasonably determined by such Lender, of (i) its cost of
obtaining the funds for the Loan being paid, prepaid, refinanced or not borrowed
or so assigned (assumed to be the LIBO Rate
<PAGE>   28
                                                                              23

applicable thereto or, in the case of a Fixed Rate Loan, the fixed rate of
interest applicable thereto) for the period from the date of such payment,
prepayment, refinancing or failure to borrow or refinance or such assignment, to
the last day of the Interest Period for such Loan (or, in the case of a failure
to borrow or refinance the Interest Period for such Loan which would have
commenced on the date of such failure) over (ii) the amount of interest (as
reasonably determined by such Lender) that would be realized by such Lender in
reemploying in similar investments the funds so paid, prepaid or not borrowed or
refinanced or so assigned for the remainder of such period or Interest Period,
as the case may be. A certificate of any Lender setting forth any amount or
amounts which such Lender is entitled to receive pursuant to this Section 2.15
shall be delivered to the Borrowers and shall be conclusive absent manifest
error.

                  SECTION 2.16. Pro Rata Treatment. Except as required under
Section 2.13, each payment or prepayment of principal of any Standby Borrowing,
each payment of interest on the Standby Loans, each payment of the Facility
Fees, each reduction of the Commitments and each refinancing of any Borrowing
with a Standby Borrowing of any Type, shall be allocated pro rata among the
Lenders in accordance with their respective Commitments (or, if such Commitments
shall have expired or been terminated, in accordance with the respective
principal amounts of their outstanding Standby Loans). Each payment of principal
of any Competitive Borrowing shall be allocated pro rata among the Lenders
participating in such Borrowing in accordance with the respective principal
amounts of their outstanding Competitive Loans comprising such Borrowing. Each
payment of interest on any Competitive Borrowing shall be allocated pro rata
among the Lenders participating in such Borrowing in accordance with the
respective amounts of accrued and unpaid interest on their outstanding
Competitive Loans comprising such Borrowing. For purposes of determining the
available Commitments of the Lenders at any time, each outstanding Competitive
Borrowing shall be deemed to have utilized the Commitments of the Lenders
(including those Lenders 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 Administrative Agent may, in its discretion, round each
Lender's percentage of such Borrowing to the next higher or lower whole dollar
amount.

                  SECTION 2.17. Sharing of Setoffs. Each Lender agrees that if
it shall, through the exercise of a right of banker's lien, setoff or
counterclaim, or pursuant to a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, obtain
payment (voluntary or involuntary) in respect of any Standby Loan or Loans as a
result of which the unpaid principal portion of its Standby Loans shall be
proportionately less than the unpaid principal portion of the Standby 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 Standby Loans of such other Lender,
so that the aggregate unpaid principal amount of the Standby Loans and
participations in the Standby Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Standby Loans then
outstanding as the principal amount of its Standby Loans prior to such exercise
of banker's lien, setoff or counterclaim or other event was to the principal
amount of all Standby Loans outstanding prior to such exercise of banker's lien,
setoff or counterclaim or other event;
<PAGE>   29
                                                                              24

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. Any Lender holding a participation in a
Standby 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
to such Lender by reason thereof as fully as if such Lender had made a Standby
Loan in the amount of such participation.

                  SECTION 2.18. Payments. (a) The Borrowers shall make each
payment (including principal of or interest on any Borrowing and any Facility
Fees or other amounts) hereunder from an account in the United States not later
than 12:00 noon, New York City time, on the date when due in dollars to the
Administrative Agent at its offices at 270 Park Avenue, New York, New York, in
immediately available funds, without setoff, counterclaim or other deductions.

                  (b) Whenever any payment (including principal of or interest
on any Borrowing or any Facility 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 Facility Fees,
if applicable.

                  SECTION 2.19. Duty to Mitigate; Assignment of Commitments
Under Certain Circumstances. (a) Any Lender (or Transferee) claiming any
additional amounts payable pursuant to Section 2.13 or Section 2.20 or
exercising its rights under Section 2.14 shall use reasonable efforts
(consistent with legal and regulatory restrictions) to file any certificate or
document requested by the Company or to change the jurisdiction of its
applicable lending office if the making of such a filing or change would avoid
the need for or reduce the amount of any such additional amounts which may
thereafter accrue or avoid the circumstances giving rise to such exercise and
would not, in the sole determination of such Lender (or Transferee), be
otherwise disadvantageous to such Lender (or Transferee).

                  (b) In the event that any Lender shall have delivered a notice
or certificate pursuant to Section 2.10(b), 2.13 or 2.14, or the Borrower shall
be required to make additional payments to any Lender under Section 2.20, the
Company shall have the right, at its own expense (which shall include the
processing and recordation fee referred to in Section 9.04(b)), upon notice to
such Lender and the Administrative Agent, to require such Lender to transfer and
assign without recourse (in accordance with and subject to the restrictions
contained in Section 9.04) all interests, rights and obligations contained
hereunder to another financial institution approved by the Administrative Agent
(which approval shall not be unreasonably withheld) which shall assume such
obligations; provided that (i) no such assignment shall conflict with any law,
rule or regulation or order of any Governmental Authority and (ii) the assignee
or the Borrowers, as the case may be, shall pay to the affected Lender in
immediately available funds on the date of such assignment the principal of and
interest accrued to the date of payment on the Loans made by it hereunder and
all other amounts accrued for its account or owed to it hereunder.
<PAGE>   30
                                                                              25

                  SECTION 2.20. Taxes. (a) Any and all payments to the Lenders
hereunder shall be made, in accordance with Section 2.18, free and clear of and
without deduction for any and all current or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding (i) income taxes imposed on the net income of the Administrative Agent
or any Lender (or any transferee or assignee thereof, including a participation
holder (any such entity a "Transferee")) and (ii) franchise taxes imposed on the
net income of the Administrative Agent or any Lender (or Transferee), in each
case by the jurisdiction under the laws of which the Administrative Agent or
such Lender (or Transferee) is organized or any political subdivision thereof
(all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities, collectively or individually, "Taxes"). If any Borrower shall
be required to deduct any Taxes from or in respect of any sum payable hereunder
to any Lender (or any Transferee) or the Administrative Agent, (i) the sum
payable shall be increased by the amount (an "additional amount") necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.20) such Lender (or Transferee) or
the Administrative 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) such
Borrower shall make such deductions and (iii) such Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with
applicable law.

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

                  (c) The Borrowers shall indemnify each Lender (or Transferee)
and the Administrative Agent for the full amount of Taxes and Other Taxes paid
by such Lender (or Transferee) or the Administrative Agent, as the case may be,
and any liability (including penalties, interest and expenses (including
reasonable attorney's fees and expenses)) arising therefrom or with respect
thereto. A certificate as to the amount of such payment or liability prepared by
a Lender, or the Administrative Agent on its behalf, absent manifest error,
shall be final, conclusive and binding for all purposes. Such indemnification
shall be made within 30 days after the date the Lender (or Transferee) or the
Administrative Agent, as the case may be, makes written demand therefor.

                  (d) If a Lender (or Transferee) or the Administrative Agent
shall become aware that it is entitled to claim a refund from a Governmental
Authority in respect of Taxes or Other Taxes as to which it has been indemnified
by the Borrowers, or with respect to which the Borrowers have paid additional
amounts, pursuant to this Section 2.20, it shall promptly notify the Borrowers
of the availability of such refund claim and shall, within 30 days after receipt
of a request by the Borrowers, make a claim to such Governmental Authority for
such refund at the Borrowers' expense. If a Lender (or Transferee) or the
Administrative Agent receives a refund (including pursuant to a claim for refund
made pursuant to the preceding sentence) in respect of any Taxes or Other Taxes
as to which it has been indemnified by the Borrowers or with respect to which
the Borrowers have paid additional amounts pursuant to this Section 2.20, it
shall within 30 days from the date of such receipt pay over such refund to the
Borrowers (but only to the extent
<PAGE>   31
                                                                              26

of indemnity payments made, or additional amounts paid, by the Borrowers under
this Section 2.20 with respect to the Taxes or Other Taxes giving rise to such
refund), without interest (other than interest paid by the relevant Governmental
Authority with respect to such refund); provided, however, that the Borrowers,
upon the request of such Lender (or Transferee) or the Administrative Agent,
agree to repay the amount paid over to the Borrowers (plus penalties, interest
or other charges) to such Lender (or Transferee) or the Administrative Agent in
the event such Lender (or Transferee) or the Administrative Agent is required to
repay such refund to such Governmental Authority.

                  (e) As soon as practicable after the date of any payment of
Taxes or Other Taxes by the Borrowers to the relevant Governmental Authority,
the Borrowers will deliver to the Administrative Agent, at its address referred
to in Section 9.01, the original or a certified copy of a receipt issued by such
Governmental Authority evidencing payment thereof.

                  (f) Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.20
shall survive the payment in full of the principal of and interest on all Loans
made hereunder for a period of 3 years.

                  (g) Each Non-U.S. Lender shall deliver to the Company and the
Administrative Agent two copies of either United States Internal Revenue Service
Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming
exemption from U.S. Federal withholding tax under Section 871(h) or 881(c) of
the Code with respect to payments of "portfolio interest", a Form W-8, or any
subsequent versions thereof or successors thereto (and, if such Non-U.S. Lender
delivers a Form W-8, a certificate representing that such Non-U.S. Lender is not
a bank for purposes of Section 881(c) of the Code, is not a 10-percent
shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the
Company and is not a controlled foreign corporation related to the Company
(within the meaning of Section 864(d)(4) of the Code)), properly completed and
duly executed by such Non-U.S. Lender claiming complete exemption from, or
reduced rate of, U.S. Federal withholding tax on payments by the Company under
this Agreement. Such forms shall be delivered by each Non-U.S. Lender on or
before the date it becomes a party to this Agreement (or, in the case of a
Transferee that is a participation holder, on or before the date such
participation holder becomes a Transferee hereunder) and on or before the date,
if any, such Non-U.S. Lender changes its applicable lending office by
designating a different lending office (a "New Lending Office"). In addition,
each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S. Lender.
Notwithstanding any other provision of this Section 2.20(g), a Non-U.S. Lender
shall not be required to deliver any form pursuant to this Section 2.20(g) that
such Non-U.S. Lender is not legally able to deliver.

                  (h) The Borrowers shall not be required to indemnify any
Non-U.S. Lender, or to pay any additional amounts to any Non-U.S. Lender, in
respect of United States Federal withholding tax pursuant to paragraph (a) or
(c) above to the extent that (i) the obligation to withhold amounts with respect
to United States Federal withholding tax existed on the date such Non-U.S.
Lender became a party to this Agreement (or, in the case of a Transferee that is
a participation holder, on the date such participation holder became a
Transferee hereunder) or, with respect to payments to a New Lending Office, the
date such Non-U.S. Lender designated such
<PAGE>   32
                                                                              27

New Lending Office with respect to a Loan; provided, however, that this clause
(i) shall not apply to any Transferee or New Lending Office that becomes a
Transferee or New Lending Office as a result of an assignment, participation,
transfer or designation made at the request of the Company; and provided
further, however, that this clause (i) shall not apply to the extent the
indemnity payment or additional amounts any Transferee, or Lender (or
Transferee) through a New Lending Office, would be entitled to receive (without
regard to this clause (i)) do not exceed the indemnity payment or additional
amounts that the person making the assignment, participation or transfer to such
Transferee, or Lender (or Transferee) making the designation of such New Lending
Office, would have been entitled to receive in the absence of such assignment,
participation, transfer or designation or (ii) the obligation to pay such
additional amounts would not have arisen but for a failure by such Non-U.S.
Lender to comply with the provisions of paragraph (g) above.

                  (i) Any Lender (or Transferee) claiming any indemnity payment
or additional amounts payable pursuant to this Section 2.20 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by the Company or to
change the jurisdiction of its applicable lending office if the making of such a
filing or change would avoid the need for or reduce the amount of any such
indemnity payment or additional amounts that may thereafter accrue and would
not, in the sole determination of such Lender (or Transferee), be otherwise
disadvantageous to such Lender (or Transferee).

                  (j) Nothing contained in this Section 2.20 shall require any
Lender (or Transferee) or the Administrative Agent to make available any of its
tax returns (or any other information that it deems to be confidential or
proprietary).

                                   ARTICLE III

                         Representations and Warranties

        The Company represents and warrants to each of the Lenders that:

                  SECTION 3.01. Corporate Existence and Power. The Company and
each Borrowing Subsidiary is a corporation duly incorporated, validly existing
and in good standing under the laws of the jurisdiction of its incorporation,
and has all corporate powers and all material governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted.

                  SECTION 3.02. Corporate and Governmental Authorization;
Contravention. The execution, delivery and performance by the Company of this
Agreement (a) is within the Company's corporate powers, (b) has been duly
authorized by all necessary corporate action, (c) requires no action by or in
respect of, or filing with, any Governmental Authority and (d) does not (i)
contravene, or constitute a default under, any applicable provision of law or
regulation either of the United States or a particular state thereof or of the
certificate of incorporation or by-laws of the Company or of any agreement,
judgment, injunction, order, decree or other instrument binding upon the Company
or (ii) result in the creation or imposition of any Lien on any asset of the
Company or any of its Subsidiaries.

                  SECTION 3.03. Binding Effect. This Agreement constitutes a

                  (h) the Company or any Subsidiary shall (i) voluntarily
         commence any proceeding or file any petition seeking relief under Title
         11 of the United States Code, as now constituted or hereafter amended,
         or any other Federal or state bankruptcy, insolvency, receivership or
         similar law, (ii) consent to the institution of, or fail to contest in

                  (j) a Reportable Event or Reportable Events, or a failure to
         make a required installment or other payment (within the meaning of
         Section 412(n)(l) of the Code), shall have occurred with respect to any

         such Reportable Event to the Administrative Agent, the Administrative

         Lenders have made a determination that, on the basis of such Reportable
         Event or Reportable Events or the failure to make a required payment,
         there are reasonable grounds (A) for the termination of such Plan or
         Plans by the PBGC, (B) for the appointment by the appropriate United
         States District Court of a trustee to administer such Plan or Plans or
         (C) for the imposition of a lien in favor of a Plan and (ii) as a
         result thereof an Event of Default exists hereunder; or a trustee shall
         be appointed by a United States District Court to administer any such
         Plan or Plans; or the PBGC shall institute proceedings to terminate any
         Plan or Plans;

                  (k) (i) the Company or any ERISA Affiliate shall have been
         notified by the sponsor of a Multiemployer Plan that it has incurred
         Withdrawal Liability to such Multiemployer Plan, (ii) the Borrower or
         such ERISA Affiliate does not have reasonable grounds for contesting
         such Withdrawal Liability or is not in fact contesting such Withdrawal
         Liability in a timely and appropriate manner and (iii) the amount of
         the Withdrawal Liability specified in such notice, when aggregated with
         all other amounts required to be paid to Multiemployer Plans in
         connection with Withdrawal Liabilities (determined as of the date or
         dates of such notification), exceeds $5,000,000 or requires payments
         exceeding $1,000,000 in any year;

                  (1) the Company or any ERISA Affiliate shall have been
         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or is being terminated, within the meaning of
         Title IV of ERISA, if solely as a result of such reorganization or
         termination the aggregate annual contributions of the Company and its
         ERISA Affiliates to all Multiemployer Plans that are then in
         reorganization or have been or are being terminated have been or will
         be increased over the amounts required to be contributed to such
         Multiemployer Plans for their most recently completed plan years by an
         amount exceeding $1,000,000;

                  (m) any guarantee purported to be created by Article VII
         hereof shall cease to be, or shall be asserted by the Company not to
         be, a valid and enforceable guarantee of the Guaranteed Obligations; or

                  (n) a Change in Control shall occur;

then, and in every such event (other than an event with respect to the Company
described in paragraph (g) or (h) above), and at any time thereafter during the
continuance of such event, the Administrative Agent, at the request of the
Required Lenders, shall, by notice to the Company, take either or both of the
following actions, at the same or different times: (i) terminate forthwith the
Commitments and (ii) declare the Loans then outstanding to be forthwith due and
payable in whole or in part, whereupon the principal of the Loans so declared to
be due and payable, together
<PAGE>   45
                                                                              40

with accrued interest thereon and any unpaid accrued Facility Fees and all other
liabilities of the Borrowers accrued hereunder, shall become forthwith due and
payable, without presentment, demand, protest or any other notice of any kind,
all of which are hereby expressly waived anything contained herein to the
contrary notwithstanding; and, in any event with respect to the Company
described in paragraph (g) or (h) above, the Commitments shall automatically
terminate and the principal of the Loans then outstanding, together with accrued
interest thereon and any unpaid accrued Facility Fees and all other liabilities
of the Borrowers accrued hereunder shall automatically become due and payable,
without presentment, demand, protest or any other notice of any kind, all of
which are hereby expressly waived anything contained herein to the contrary
notwithstanding.

                                   ARTICLE VII

                                    Guarantee

                  The Company unconditionally and irrevocably guarantees the due
and punctual payment and performance, when and as due, whether at maturity, by
acceleration, upon one or more dates set for prepayment or otherwise, of the
Guaranteed Obligations. The Company further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from it and that it will remain bound upon its guarantee
notwithstanding any extension or renewal of any Guaranteed Obligations.

                  The Company waives presentment to, demand of payment from and
protest to the Borrowing Subsidiaries of any of the Guaranteed Obligations, and
also waives notice of acceptance of its guarantee and notice of protest for
nonpayment. The obligations of the Company hereunder shall not be affected by
(a) the failure of any Lender or the Administrative Agent to assert any claim or
demand or to enforce any right or remedy against the Borrowing Subsidiaries
under the provisions of this Agreement or otherwise; (b) any rescission, waiver,
amendment or modification of any of the terms or provisions of this Agreement,
any guarantee or any other agreement; or (c) the failure of any Lender or the
Administrative Agent to exercise any right or remedy against any other guarantor
of the Guaranteed Obligations.

                  The Company further agrees that its guarantee constitutes a
guarantee of payment when due and not of collection, and waives any right to
require that any resort be had by the Administrative Agent or any Lender to any
security, if any, held for payment of the Guaranteed Obligations or to any
balance of any deposit account or credit on its books, in favor of the Borrowing
Subsidiaries or any other person.

                  The obligations of the Company hereunder shall not be subject
to any reduction, limitation, impairment or termination for any reason,
including, without limitation, any claim of waiver, release, surrender,
alteration or compromise, and shall not be subject to any defense or setoff,
counterclaim, recoupment or termination whatsoever by reason of the invalidity,
illegality or unenforceability of the Guaranteed Obligations or otherwise.
Without limiting the generality of the foregoing, the obligations of the Company
hereunder shall not be discharged or impaired or otherwise affected by the
failure of the Administrative Agent or any Lender to assert any claim or
<PAGE>   46
                                                                              41

demand or to enforce any remedy under this Agreement, any guarantee or any other
agreement, by any waiver or modification of any provision of any thereof, by any
default, failure or delay, willful or otherwise, in the performance of the
Guaranteed Obligations, or by any other act or omission which may or might in
any manner or to any extent vary the risk of the Company or otherwise operate as
a discharge of the Company as a matter of law or equity.

                  To the extent permitted by applicable law, the Company waives
any defense based on or arising out of any defense available to the Borrowing
Subsidiaries, including any defense based on or arising out of any disability of
the Borrowing Subsidiaries, or the unenforceability of the Guaranteed
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of the Borrowing Subsidiaries, other than final payment in full
of the Guaranteed Obligations. The Administrative Agent and the Lenders may, at
their election, foreclose on any security held by one or more of them by one or
more judicial or non-judicial sales, or exercise any other right or remedy
available to them against the Borrowing Subsidiaries, or any security without
affecting or impairing in any way the liability of the Company hereunder except
to the extent the Guaranteed Obligations have been fully and finally paid. The
Company waives any defense arising out of any such election even though such
election operates to impair or to extinguish any right of reimbursement or
subrogation or other right or remedy of the Company against any Borrowing
Subsidiary or any security.

                  The Company further agrees that its guarantee shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal of or interest on any Guaranteed Obligation is
rescinded or must otherwise be restored by any Lender upon the bankruptcy or
reorganization of any Borrowing Subsidiary or otherwise.

                  In furtherance of the foregoing and not in limitation of any
other right which the Administrative Agent or any Lender may have at law or in
equity against the Company by virtue hereof, upon the failure of any Borrowing
Subsidiary to pay any Guaranteed Obligation when and as the same shall become
due, whether at maturity, by acceleration, after notice of prepayment or
otherwise, the Company hereby promises to and will, upon receipt of written
demand by the Administrative Agent or any Lender, forthwith pay or cause to be
paid to the Administrative Agent or such Lender in cash the amount of such
unpaid Guaranteed Obligation.

                  Upon payment by the Company of any sums to the Administrative
Agent or any Lender, as provided above, all rights of the Company against the
other Borrowers arising as a result thereof by way of right of subrogation or
otherwise shall in all respects be subordinated and junior in right of payment
to the prior indefeasible payment in full of all the Guaranteed Obligations to
the Administrative Agent and the Lenders.

                                  ARTICLE VIII

                            The Administrative Agent

                  In order to expedite the transactions contemplated by this
Agreement, The Chase Manhattan Bank is hereby appointed to act as Administrative
Agent on behalf of the Lenders.
<PAGE>   47
                                                                              42

Each of the Lenders hereby irrevocably authorizes the Administrative Agent to
take such actions on behalf of such Lender or holder and to exercise such powers
as are specifically delegated to the Administrative Agent by the terms and
provisions hereof, together with such actions and powers as are reasonably
incidental thereto. The Administrative Agent is hereby expressly authorized by
the Lenders, 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 Borrowers of any Event of Default of which
the Administrative Agent has actual knowledge acquired in connection with its
agency hereunder; and (c) to distribute promptly to each Lender copies of all
notices, financial statements and other materials delivered by the Borrowers
pursuant to this Agreement as received by the Administrative Agent.

                  Neither the Administrative 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 or her own gross negligence or
willful misconduct, or be responsible for any statement, warranty or
representation herein or the contents of any document delivered in connection
herewith, or be required to ascertain or to make any inquiry concerning the
performance or observance by the Borrowers of any of the terms, conditions,
covenants or agreements contained in this Agreement. The Administrative 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 Administrative Agent may deem and treat the Lender that makes
any Loan as the holder of the indebtedness resulting therefrom for all purposes
hereof until it shall have received notice from such Lender, given as provided
herein, of the transfer thereof. The Administrative 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 Administrative Agent
shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. Neither the
Administrative Agent nor any of its directors, officers, employees or agents
shall have any responsibility to the Borrowers on account of the failure of or
delay in performance or breach by any other 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 Borrowers of any of their respective
obligations hereunder or in connection herewith. The Administrative 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 Administrative 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
Administrative Agent as provided below, the Administrative Agent may resign at
any time by notifying the Lenders and the Company. Upon any such resignation,
the Required Lenders shall have the right to appoint a
<PAGE>   48
                                                                              43

successor Administrative Agent reasonably acceptable to the Company. If no
successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative Agent
gives notice of its resignation, then, the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative 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 Administrative 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 Administrative Agent and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 9.05 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 Administrative Agent.

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

                  Each Lender agrees (i) to reimburse the Administrative Agent,
on demand, in the amount of its pro rata share (based on its Commitment
hereunder or, if the Commitments shall have been terminated, the amount of its
outstanding Loans) of any out-of-pocket expenses incurred for the benefit of the
Lenders by the Administrative Agent, including reasonable counsel fees and
compensation of agents paid for services rendered on behalf of the Lenders,
which shall not have been reimbursed by the Borrowers and (ii) to indemnify and
hold harmless the Administrative 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 Administrative Agent in any way relating to or arising out
of this Agreement or any action taken or omitted by it under this Agreement to
the extent the same shall not have been reimbursed by the Borrowers; provided
that no Lender shall be liable to the Administrative Agent for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the gross negligence or
willful misconduct of the Administrative Agent or any of its directors,
officers, employees or agents. Each Lender agrees that any allocation made in
good faith by the Administrative Agent of expenses or other amounts referred to
in this paragraph between this Agreement and the Five-Year Facility shall be
conclusive and binding for all purposes.

                  Each Lender acknowledges that it has, independently and
without reliance upon the Administrative 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
Administrative 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

agreements, representations and warranties made by the Borrowers herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Agreement shall be considered to have been relied upon by

                  SECTION 9.04. Successors and Assigns. (a) Whenever in this
Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of any party that are contained in this
Agreement shall bind and inure to the benefit of its successors and assigns.

                  (b) Each Lender may assign to one or more assignees all or a
portion of its interests, rights and obligations under this Agreement (including
all or a portion of its Commitment and the Loans at the time owing to it);
provided, however, that (i) except in the case of an assignment to a Lender or a
domestic Affiliate of a Lender, the Company must give its prior written consent
to such assignment (which consent shall not be unreasonably withheld); provided,
however, that the consent of the Company shall not be required to any such
assignment during the continuance of any Event of Default, (ii) the amount of
the Commitment (or, after the Termination Date, the outstanding Loans) of the
assigning Lender subject to each such assignment (determined as of the date the
Assignment and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $10,000,000, (iii) the parties to
each such assignment shall execute and deliver to the Administrative Agent an
Assignment and Acceptance, and a processing and recordation fee of $3,500 and
(iv) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire. Upon acceptance and
recording pursuant to paragraph (e) of this Section 9.04, from and after the
effective date specified in each Assignment and Acceptance, which effective date
shall be at least five Business Days after the execution thereof, (A) the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement and (B) the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto (but shall continue to be entitled to the benefits of Sections
2.13, 2.15, 2.20 and 9.05, as well as to any Facility Fees accrued for its
account hereunder and not yet paid)). Notwithstanding the foregoing, any Lender
assigning its rights and obligations under this Agreement may retain any
Competitive Loans made by it outstanding at such time, and in such case shall
retain its rights hereunder in respect of any Loans so retained until such Loans
have been repaid in full in accordance with this Agreement.

                  (c) By executing and delivering an Assignment and Acceptance,
the assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:
(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim, (ii)
except as set forth in (i) above, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement, or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto or the financial condition of the Borrowers or the performance or
observance by the Borrowers of any obligations under this Agreement or any other
instrument or document furnished pursuant hereto; (iii) such assignee represents
and warrants that it is legally authorized to enter into such Assignment and
Acceptance; (iv) such assignee confirms that it has received a copy of this
Agreement, together with copies of the most recent financial statements
delivered pursuant to Sec-
<PAGE>   51
                                                                              46

tion 5.01 and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such Assignment and
Acceptance; (v) such assignee will independently and without reliance upon the
Administrative 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 Administrative
Agent to take such action as agent on its behalf and to exercise such powers
under this Agreement as are delegated to the Administrative Agent by the terms
hereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

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

                  (e) Upon its receipt of a duly completed Assignment and
Acceptance executed by an assigning Lender and an assignee together with an
Administrative Questionnaire completed in respect of the assignee (unless the
assignee shall already be a Lender hereunder), the processing and recordation
fee referred to in paragraph (b) above and, if required, the written consent of
the Company to such assignment, the Administrative Agent shall (i) accept such
Assignment and Acceptance and (ii) record the information contained therein in
the Register.

                  (f) Each Lender may 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 2.20 to the same
extent as if it was the selling Lender (but limited to the amount that could
have been claimed by the selling Lender had it continued to hold the interest of
such participating bank or other entity), except that all claims made pursuant
to such Sections shall be made through such selling Lender, and (iv) the
Borrowers, the Administrative 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 selling Lender shall
retain the sole right to enforce the obligations of the Borrowers 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, extending any scheduled principal payment date
or date fixed for the payment of interest on the Loans or changing or extending
the Commitments).

                  (g) Any Lender or participant may, in connection with any
assignment or participation or proposed assignment or participation pursuant to
this Section, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrowers furnished to such Lender;
provided that, prior to any such disclosure, each such assignee or participant
or proposed assignee or participant shall execute an agreement whereby such
assignee or participant shall agree (subject to customary exceptions) to
preserve the confidentiality of any such information.

                  (h) The Borrowers shall not assign or delegate any rights and
duties hereunder without the prior written consent of all Lenders.

                  (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, each Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes evidencing the Loans made to such Borrower by the assigning Lender
hereunder.

                  SECTION 9.05. Expenses; Indemnity. (a) The Borrowers agree,
jointly and severally, to pay the fees and disbursements of counsel for the
Administrative Agent in connection with entering into this Agreement and in
connection with any amendments, modifications or waivers of the provisions
hereof, and agree, jointly and severally, to pay the reasonable out-of-pocket
expenses incurred by the Administrative Agent or any Lender in connection with
the enforcement or protection of their rights in connection with this Agreement
or the Loans made hereunder, including the reasonable fees and disbursements of
counsel for the Administrative Agent or any Lender.

                  (b) The Borrowers agree, jointly and severally, to indemnify
the Administrative Agent, each Lender, each of their Affiliates and the
directors, officers, employees and agents of the foregoing (each such person
being called an "Indemnitee") against, and to hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses,
including reasonable counsel 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 finally determined
by a court of competent jurisdiction to have resulted from the gross negligence
or willful misconduct of such Indemnitee or from such Indemnitee's violation of
the Federal securities laws prohibiting insider trading.

                  (c) The provisions of this Section shall remain operative and
in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any investigation made by or on
<PAGE>   53
                                                                              48

behalf of the Administrative Agent or any Lender. All amounts due under this
Section shall be payable on written demand therefor.

                  SECTION 9.06. Applicable Law. THIS AGREEMENT SHALL BE
CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

                  SECTION 9.07. Waivers; Amendment. (a) No failure or delay of
the Administrative 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 Administrative 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 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 any
Borrower or any Subsidiary in any case shall entitle such party to any other or
further notice or demand in similar or other circumstances.

                  (b) Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by the Borrowers 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 or extend the
Commitment or decrease the Facility Fee of any Lender or extend any date for
payment thereof without the prior written consent of such Lender, (iii) amend or
modify the provisions of Section 2.16 or Section 9.04(h), the provisions of this
Section or the definition of the "Required Lenders," or (iv) release the Company
from any of its obligations under Article VII hereof without the prior written
consent of each Lender; provided further, however, that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative
Agent hereunder without the prior written consent of the Administrative 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 9.08. Entire Agreement. This Agreement constitutes 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. Nothing in this Agreement, expressed or
implied, is intended to confer upon any party other than the parties hereto any
rights, remedies, obligations or liabilities under or by reason of this
Agreement.

                  SECTION 9.09. 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
<PAGE>   54
                                                                              49

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 9.10. 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 9.03.

                  SECTION 9.11. 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 9.12. Right of Setoff. If an Event of Default shall
have occurred and be continuing, each Lender is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Lender
to or for the credit or account of the Company and any Borrowing Subsidiary now
or hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. Each Lender agrees promptly to
notify the Company after such setoff and application made by such Lender, but
the failure to give such notice shall not affect the validity of such setoff and
application. The rights of each Lender under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) which such Lender may have.

                  SECTION 9.13. Jurisdiction; Consent to Service of Process. (a)
Each Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement, or for recognition or enforcement of any judgment,
and each of the parties hereto hereby irrevocably and unconditionally agrees
that all claims in respect of any such action or proceeding may be heard and
determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Subject to the foregoing and to paragraph (b) below, nothing in this Agreement
shall affect any right that any party hereto may otherwise have to bring any
action or proceeding relating to this Agreement against any other party hereto
in the courts of any jurisdiction.

                  (b) Each Borrower hereby irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection which it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement in any New
York State or Federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

                                                                              50

                  (c) Each Borrower hereby irrevocably consents to service of
process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

                  SECTION 9.14. Waiver of Jury Trial. Each party hereto hereby
waives, to the fullest extent permitted by applicable law, any right it may have
to a trial by jury in respect of any litigation directly or indirectly arising
out of, under or in connection with this Agreement. Each party hereto (a)
certifies that no representative, agent or attorney of any other party has
represented, expressly or otherwise, that such other party would not, in the
event of litigation, seek to enforce the foregoing waiver and (b) acknowledges
that it and other parties hereto have been induced to enter into this Agreement
by, among other things, the mutual waivers and certification in this Section.

                  SECTION 9.15. Addition of Borrowing Subsidiaries. Each wholly
owned Subsidiary of the Company which shall deliver to the Administrative Agent
a Borrowing Subsidiary Agreement executed by such Subsidiary and the Company
shall, upon such delivery and without further act, become a party hereto and a
Borrower hereunder with the same effect as if it had been an original party to
this Agreement.

                  SECTION 9.16. Confidentiality. Each Lender and the
Administrative Agent agree to keep confidential the Information, except that any
such Lender and the Administrative Agent shall be permitted to disclose
Information (a) to such of its officers, directors, employees, agents and
representatives as need to know such Information; (b) to the extent required by
applicable laws and regulations or by any subpoena or similar legal process,
including with respect to the enforcement of this Agreement, provided that such
Lender and the Administrative Agent shall use reasonable efforts to notify the
Company of such prospective disclosure a reasonable time prior to any such
disclosure and shall take such actions reasonably requested by the Company to
assist the Company in obtaining a protective order or confidential treatment
with respect to such Information (it being understood that failure to give such
notice after having made any such reasonable efforts shall not result in any
liability hereunder to such Lender or the Administrative Agent, as the case may
be); (c) to the extent requested by any bank regulatory authority; (d) to the
extent such Information (i) becomes publicly available other than as a result of
a breach of this Agreement, (ii) becomes available to such Lender or the
Administrative Agent on a non-confidential basis from a source other than the
Company and its Affiliates or (iii) was available to such Lender or the
Administrative Agent on a non-confidential basis prior to its disclosure to such
Lender or the Administrative Agent by the Company or its Affiliates; (e) to any
Affiliate of or any actual or prospective assignee or participant in any rights
of such Lender or the Administrative Agent under this Agreement, provided that
such Affiliate, assignee or participant delivers to the Administrative Agent or
such Lender, as applicable, a confidentiality letter containing substantially
the undertakings set forth in this Section 9.16 and (f) to the extent the
Company shall have consented to such disclosure in writing.

                  SECTION 9.17. Collateral. Each of the Lenders represents to
each of the other Lenders that it in good faith is not relying upon any Margin
Stock as collateral in the extension or maintenance of the credit provided for
in this Agreement.

                  SECTION 9.18. Interest Rate Limitation. Notwithstanding
anything herein to the contrary, if at any time the applicable interest rate,
together with all fees and charges which are treated as interest under
applicable law (collectively the "Charges"), as provided for herein or in any
other document executed in connection herewith, or otherwise contracted for,
charged, received, taken or reserved by any Lender, shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
received or reserved by such Lender in accordance with applicable law, all
Charges payable to such Lender shall be limited to the Maximum Rate.
