                                 LOAN AGREEMENT

                THIS LOAN AGREEMENT is entered into as of December 22, 1999, by
and between C. Thomas Faulders, III, an individual residing at 6721 Benjamin
Street, McLean, Virginia 22101 ("BORROWER"), and LCC International, Inc., a
Delaware corporation having its principal office at 7925 Jones Branch Drive,
McLean, Virginia 22102 (the "COMPANY").

                In consideration of the mutual covenants and agreements
hereinafter set forth, the parties hereby agree as follows:

1.      LOAN

        1.1.    LOAN

                On the date hereof the Company will make a loan (the "LOAN") to
Borrower in the principal amount of One Million Six Hundred Twenty Five Thousand
Dollars ($1,625,000.00), said Loan to be for a term of five (5) years commencing
on the date hereof or until the termination of Borrower's employment as the
Chairman and Chief Executive Officer of the Company, if earlier, and to be
evidenced by a promissory note of Borrower (the "NOTE"), dated the date hereof
and in substantially the form of the promissory note attached hereto as Exhibit
A (the terms and provisions of which Note are incorporated herein by reference).

        1.2.    USE OF LOAN PROCEEDS

                The proceeds of the Loan shall be used only for the purchase of
the Company's Class A common stock, par value $.01 per share, (the "LCC SHARES")
from the Company on the date hereof.

        1.3.    BONUS FOR INTEREST PAYMENTS

                On each date on which interest is due and payable under the
Note, provided that Borrower is employed as Chairman and Chief Executive of the
Company on such date and no Event of Default (as defined in SECTION 4.1) all
have occurred and be continuing on such date, the Company will pay Borrower a
bonus equal to the amount necessary to net Borrower, after applicable state and
federal taxes, the amount of the interest payment due on such date.

        1.4.    FORGIVENESS OF INDEBTEDNESS

                In the event of (a) the sale of all or substantially all of the
assets of the Company to another person or entity, (b) a merger, acquisition or
other transaction in which the Company is the surviving corporation that results
in any person or entity (other than persons or entities who are holders of five
percent (5%) more of the stock of the Company at the time the transaction is
approved by the shareholders of the company and other than any Affiliate of the
Company (as defined below)) acquiring beneficial ownership of fifty-one percent
(51%) or more of the combined voting power of all classes of stock of the
Company, excluding any change in voting control arising as a result of the
conversion of the Class B common stock, par value $.01 per share, of the Company
to Class A common stock, par value $.01 per share, of the Company or any
distribution by RF Investors, L.L.C. to any of its direct or indirect owners or
their respective Affiliates or (c) a merger, consolidation or reorganization of
the Company with one or more other persons or entities where the Company is not
the surviving entity and such transaction results in a change of beneficial
ownership of the combined voting power of all classes of stock of the Company as
described in the preceding clause (b), then all amounts outstanding under this
Agreement and the Note shall be forgiven to the extent that the forgiveness of
such amounts does not (together with all other items of compensation considered
in the applicable tax calculation) result in an excise tax imposed by Section
4999 of the Internal Revenue Code of 1986, as amended (i.e., a "golden
parachute" excise tax). For purposes of the foregoing, the term "AFFILIATE"
shall mean, with respect to any entity, any person or other entity that,
directly or indirectly through one or more intermediaries, controls, is
controlled by, or is under common control with, the specified entity, where the
term "CONTROL" means the possession, directly or indirectly, of the power to
direct or cause the direction of the management and policies of an entity,
whether through the ownership of voting securities, by contract, or otherwise.

2.      REPRESENTATIONS AND WARRANTIES OF BORROWER

<PAGE>

(with or without due notice or lapse of time or both a default (or give rise to

mortgage, indenture, lease, contract, agreement or other instrument or
obligation to which Borrower is a party or by which he or any of his properties
or assets is bound; (ii) violate any order, writ, injunction, decree, statute,
rule or regulation applicable to Borrower, or (iii) require any filing with or
notice to any court, government agency or other governmental authority; except

condition of Borrower, and that shall not impair the effectiveness of the
transactions contemplated hereby.

        2.2.    BINDING OBLIGATION

                This Agreement has been duly and validly executed and delivered
by Borrower and constitutes a valid and binding agreement of Borrower,

adverse effect on the financial condition of Borrower.

        2.5.    TAXES

        2.6.    INVESTMENT REPRESENTATIONS.

                (a)     Borrower is acquiring the LCC Shares to be purchased
with the proceeds of the Loan for his own account as principal, for investment
and not with a view to distribution within the meaning of the Securities Act of
1933, as amended (the "ACT"). Borrower acknowledges that the LCC Shares to be
purchased with the proceeds of the Loan have not been registered under the Act,
and Borrower agrees not to sell, hypothecate or otherwise dispose of such shares
unless such shares have been registered under the Act and applicable state
securities laws or exemptions from the registration requirements of the Act and
such state laws are available and Borrower has delivered to the Company an
opinion of counsel, in form and substance satisfactory to the Company, regarding
the availability of such exemptions.

                (b)     (i) Borrower is an "accredited investor" within the
meaning of Rule 501 under the Act, (ii) Borrower's overall commitment to
investments that are not readily marketable is reasonable in relation to
Borrower's net worth, and Borrower's acquisition of the LCC Shares to be
purchased with the proceeds of the Loan will not cause such overall commitment
to become excessive, (iii) Borrower has adequate net worth and means of
providing for Borrower's current needs and personal contingencies to sustain a
complete loss of its investment in the Company, and Borrower has no need for
liquidity in its investment in the LCC Shares to be purchased with the proceeds
of the Loan, (iv) Borrower alone is capable of understanding and has evaluated
the merits and risks of investing in the Company, (v) Borrower is aware that
Borrower's right to transfer the LCC Shares to be purchased with the proceeds of
the Loan is restricted by the Act and applicable state securities laws, and of
the absence of a market for such shares, and (vi) Borrower has substantial
experience in making investment decisions of this type.

                (c)     The Company has made available to Borrower and/or
Borrower's attorney or accountant all documents that Borrower or they have
requested relating thereto and has provided answers to all of such questions.
Borrower understands and acknowledges that the Company cannot provide assurances
with respect to any projections or predictions as to the future business or
financial performance of the Company.

                (d)     Borrower recognizes that an investment in the Company
involves a high degree of risk, and he has taken full cognizance of and
understands all of the risk factors related to the acquisition of the LCC Shares
to be purchased with the proceeds of the Loan.

                (e)     If needed, Borrower has discussed with his professional
legal, tax and/or financial advisors the suitability of an investment in the
Company for Borrower's particular tax and financial situation. All information
that Borrower

                                      -4-
<PAGE>

has provided to the Company concerning itself and its financial position is
correct and complete as of the date set forth above.

3.      AFFIRMATIVE COVENANTS OF BORROWER

                Until all obligations of Borrower under this Agreement and the
Note are paid in full and performed, Borrower hereby covenants and agrees that
it shall, unless the Company otherwise consents in advance in writing:

        3.1.    TAXES, CHARGES, AND OBLIGATIONS

                Pay and discharge all taxes, assessments, and governmental
charges or levies imposed upon him or upon his income, properties or any part
thereof, prior to the date on which penalties attach thereto, provided, that,
Borrower shall not be required to pay any such tax, assessment, charge, levy,
claim, indebtedness or obligation so long as the validity thereof is being
contested by Borrower in good faith and by proper proceedings.

4.      EVENTS OF DEFAULT AND REMEDIES

        4.1.    EVENTS OF DEFAULT

                The occurrence of any one or more of the following events shall

due, any sum payable under the Note, and such failure shall continue for five
(5) Business Days (as defined in SECTION 5.11) after the date on which such
payment is due; (b) any representation or warranty made by or on behalf of
Borrower herein shall prove to have been incorrect or misleading or breached in
any respect on or as of any date as of which made; (c) Borrower shall at any
time fail to observe, satisfy or perform any of the covenants or agreements
contained in this Agreement or the Note to be observed or performed on his part,
including without limitation, those contained in SECTION 1.2 or SECTION 3

Fifty Thousand Dollars ($50,000) shall be declared to be due and payable, or
required to be prepaid (other than by a regularly scheduled prepayment), prior
to the maturity date thereof; (e) one or more judgments, decrees or orders for
the payment of money in excess of Fifty Thousand Dollars ($50,000) in the
aggregate shall be rendered against Borrower and such judgments, decrees or

consecutive days without being vacated, discharged, satisfied or stayed or
bonded pending appeal; (f) if, pursuant to or within the meaning of the United
States Bankruptcy Code or any other federal or state law relating to insolvency
or relief of debtors (a "BANKRUPTCY LAW"), Borrower shall (i) commence a
voluntary case or proceeding; (ii) consent to the entry of an order for relief
against it in an involuntary case; (iii)

                                      -5-
<PAGE>

consent to the appointment of a trustee, receiver, assignee, liquidator or
similar official; (iv) make an assignment for the benefit of its creditors; or
(v) admit in writing its inability to pay its debts as they become due; or (f)
if a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that (i) is for relief against Borrower in an involuntary case,
or (ii) appoints a trustee, receiver, assignee, liquidator or similar official
for Borrower or substantially all of Borrower's properties.

        4.2.    RIGHTS AND REMEDIES OF THE COMPANY

                Upon the occurrence of any Event of Default, the Company may,
at its option, exercise any one or more of the following rights and remedies:

foregoing, and not in substitution therefor, exercise any one or more of the

                                      NOTE

        $1,625,000                                             December 22, 1999

                FOR VALUE RECEIVED, C. THOMAS FAULDERS, III, an individual
residing at 6721 Benjamin Street, McLean, Virginia 22101 (the "MAKER"), promises
to pay to the order of LCC INTERNATIONAL, INC., a Delaware corporation, or
assigns, (the "HOLDER") on the earlier of (i) December 22, 2004 and (ii) the
date on which the Maker is no longer employed as the Chairman and Chief
Executive Officer of the Holder, at 7925 Jones Branch Drive, McLean, Virginia
22102, or at such other place as the Holder of this Note may from time to time
designate, the principal amount of One Million Six Hundred Twenty-Five Thousand
Dollars ($1,625,000), subject to adjustment as provided in Section 1.4 of the
Loan Agreement (as defined below). This Note shall bear interest on the unpaid
principal amount hereof from the date hereof, until paid in full, said interest
to be due and payable quarterly on April 1, July 1, October 1 and January 1
commencing on April 1, 2000, at a rate per annum (computed on the basis of a 360
day year and of the actual number of days elapsed) equal to 6.06%, compounded
quarterly, (the "BASE RATE"), provided that, should an Event of Default exist
and be continuing for ten (10) Business Days, interest shall instead accrue on
the outstanding principal balance of this Note from the date of such Event of
Default at the rate of the Base Rate plus three percent (3%) per annum,
compounded quarterly, until such Event of Default is cured or waived or all
principal or interest under this Note is paid in full. All payments hereunder
shall be made in lawful money of the United States of America without offset for
any amounts owed by the Holder to the Maker.

                The unpaid principal amount of this Note may be prepaid in whole
or in part at any time or times without premium or penalty. Each prepayment
shall be applied first to the payment of all interest and other amounts accrued
hereunder on the date of any such prepayment, and the balance of any such
prepayment shall be applied to outstanding principal.

                This Note is the Note referred to in that certain Loan
Agreement, dated as of the date hereof, between the Maker and the Holder (the
"LOAN AGREEMENT") and evidences the Loan advanced by the Holder to or for the
benefit of the Maker as Borrower under the Loan Agreement. Capitalized terms not
defined herein shall have the meanings given to them in the Loan Agreement.
Neither the reference to the Loan Agreement nor any provision

<PAGE>

thereof shall affect or impair the absolute and unconditional obligation of the
Maker to pay the principal amount outstanding hereunder, together with interest
accrued thereon, when due.

                The Loan Agreement provides for the acceleration of all amounts
due hereunder upon the occurrence of an Event of Default and for a discharge of
all amounts due hereunder upon the occurrence of certain events specified
therein.

                The Holder may, upon the occurrence of any Event of Default
hereunder, have resort to any collateral, whether real or personal property,
given as security for this Note in any order, and may sell and dispose of such
collateral in whole or in part, at any time or from time to time, with no
requirement on the part of the Holder of this Note to marshal assets. The Holder
shall not be required to preserve any rights in such collateral as against prior
parties. In the event that the Holder is required to give notice of any intended
disposition of collateral held as security for this Note, five (5) days' notice
given by mail or telegraph to the last known address of Maker shall be deemed to
be reasonable notice.

                The Maker promises to pay all costs and expenses (including
without limitation attorneys' fees and disbursements) incurred in connection
with the collection hereof or the enforcement by the Holder of its rights
hereunder or under the Loan Agreement or under any other instrument evidencing
or securing the obligation represented by this Note or in the protection or
realization of any collateral now or hereafter given as security for the
repayment or performance hereof.

                Each Obligor (which term shall include the Maker and all
sureties, guarantors, endorsers, and other persons assuming obligations pursuant
to this Note) under this Note hereby waives presentment, protest, demand, notice
of dishonor, and all other notices, and all defenses and pleas on the grounds of
any extension or extensions of the time of payments or the due dates of this
Note, in whole or in part, before or after maturity, with or without notice. No
renewal or extension of this Note, no release or surrender of any collateral
given as security for this Note, no release of any Obligor, and no delay in
enforcement of this Note or in exercising any right or power hereunder, shall
affect the liability of any Obligor. The pleading of any statute of limitations
as a defense to any demand against any Obligor is expressly waived.

                No single or partial exercise by the Holder of any right
hereunder, under the Loan Agreement, or under any other agreement given as
security for this Note or pertaining hereto, shall preclude any other or further
exercise thereof or the exercise of any other rights. No delay or omission on
the part of the Holder in exercising any right hereunder shall operate as a
waiver of such right or of any other right under this Note.

                  (ii)     the aggregate amount of such Borrowing, which shall

                  (iv)     whether the Money Market Quotes requested are to set
         forth a Money Market Margin or a Money Market Absolute Rate.

The Borrower may request offers to make Money Market Loans for more than one
Interest Period in a single Money Market Quote Request. No Money Market Quote
Request shall be given within five Euro-Dollar Business Days (or such other
number of days as the Borrower and the Agent may agree) of any other Money
Market Quote Request.

         (c)      INVITATION FOR MONEY MARKET QUOTES. Promptly upon receipt of a
Money Market Quote Request, the Agent shall send to the Banks by telex or

either case, such other time or date as the Borrower and the Agent shall have

the Money Market Quote Request for the first LIBOR Auction or Absolute Rate
Auction for which such change is to be effective); PROVIDED that Money Market

                  (A)      the proposed date of Borrowing,

                  (B)      the principal amount of the Money Market Loan for
         which each such offer is being made, which principal amount (w) may be
         greater than or less than the Commitment of the quoting Bank, (x) must
         be $5,000,000 or a larger integral multiple of $1,000,000, (y) may not
         exceed the principal amount of Money Market Loans for which offers were
         requested and (z) may be subject to an aggregate limitation as to the
         principal amount of Money Market Loans for which offers being made by
         such quoting Bank may be accepted,

                  (C)      in the case of a LIBOR Auction, the margin above or
         below the applicable London Interbank Offered Rate (the "Money Market
         Margin") offered for each such Money Market Loan, expressed as a
         percentage (specified to the nearest 1/10,000th of 1%) to be added to
         or subtracted from such base rate,

                  (D)      in the case of an Absolute Rate Auction, the rate of
         interest per annum (specified to the nearest 1/10,000th of 1%) (the
         "Money Market Absolute Rate") offered for each such Money Market Loan,
         and

                  (E)      the identity of the quoting Bank.

A Money Market Quote may set forth up to five separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Money Market Quotes.

         (iii)    Any Money Market Quote shall be disregarded if it:

                  (A)      is not substantially in conformity with EXHIBIT D
         hereto or does not specify all of the information required by
         subsection (d)(ii);

                  (B)      contains qualifying, conditional or similar language;

                  (C)      proposes terms other than or in addition to those set
         forth in the applicable Invitation for Money Market Quotes; or

                  (D)      arrives after the time set forth in subsection
         (d)(i).

         (e)      NOTICE TO BORROWER. The Agent shall promptly notify the
Borrower of the terms (x) of any Money Market Quote submitted by a Bank that is
in accordance with subsection (d) and (y) of any Money Market Quote that amends,
modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market Quote Request. Any
such subsequent Money Market Quote shall be disregarded by the Agent unless such
subsequent Money Market Quote is submitted solely to correct a manifest error in
such former Money Market Quote. The Agent's notice to the Borrower shall specify
(A) the aggregate principal amount of Money Market Loans for which offers have
been received for each Interest Period specified in the related Money Market
Quote Request, (B) the respective principal amounts and Money Market Margins or
Money Market Absolute Rates, as the case

<PAGE>
                                      -17-

may be, so offered and (C) if applicable, limitations on the aggregate principal
amount of Money Market Loans for which offers in any single Money Market Quote
may be accepted.

         (f)      ACCEPTANCE AND NOTICE BY BORROWER. Not later than (x) 10:00
A.M. (Boston time) on the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) 10:15 A.M. (Boston
time) or 30 minutes after the receipt of the Money Market Quote from the Agent
on the proposed date of Borrowing, in the case of an Absolute Rate Auction (or,
in either case, such other time or date as the Borrower and the Agent shall have
mutually agreed and shall have notified to the Banks not later than the date of
the Money Market Quote Request for the first LIBOR Auction or Absolute Rate
Auction for which such change is to be effective), the Borrower shall notify the
Agent of its acceptance or non-acceptance of the offers so notified to it
pursuant to subsection (e). In the case of acceptance, such notice (a "Notice of
Money Market Borrowing") shall specify the aggregate principal amount of offers
for each Interest Period that are accepted. The Borrower may accept any Money
Market Quote in whole or in part; PROVIDED that:

                  (i)      the aggregate principal amount of each Money Market
         Borrowing may not exceed the applicable amount set forth in the related
         Money Market Quote Request,

                  (ii)     the principal amount of each Money Market Borrowing
         must be $10,000,000 or a larger multiple of $1,000,000,

                  (iii)    acceptance of offers may only be made on the basis of
         ascending Money Market Margins or Money Market Absolute Rates, as the
         case may be, and

                  (iv)     the Borrower may not accept any offer that is
         described in subsection (d)(iii) or that otherwise fails to comply with
         the requirements of this Agreement.

         (g)      ALLOCATION BY AGENT. If offers are made by two or more Banks
with the same Money Market Margins or Money Market Absolute Rates, as the case
may be, for a greater aggregate principal amount than the amount in respect of
which such offers are accepted for the related Interest Period, the principal
amount of Money Market Loans in respect of which such offers are accepted shall
be allocated by the Agent among such Banks as nearly as possible (in integral
multiples of $1,000,000, as the Agent may deem appropriate) in proportion to the
aggregate principal amounts of such offers. Determinations by the Agent of the
amounts of Money Market Loans shall be conclusive in the absence of manifest
error.

         SECTION 2.4.  NOTICE TO BANKS; FUNDING OF LOANS.

         (a)      Upon receipt of a Notice of Borrowing, the Agent shall
promptly notify each Bank of the contents thereof and of such Bank's share (if
any) of such Borrowing and such Notice of Borrowing shall not thereafter be
revocable by the Borrower.

         (b)      Not later than 12:00 Noon (Boston time) on the date of each
Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in
Federal or other funds immediately available in Boston, to the Agent at its
address specified in or pursuant to Section 9.1. Unless the Agent

<PAGE>
                                      -18-

determines that any applicable condition specified in Article III has not been
satisfied, the Agent will make the funds so received from the Banks available to
the Borrower at the Agent's aforesaid address.

         (c)      If any Bank makes a new Loan hereunder on a day on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the amount being repaid shall be made available by such Bank to the Agent as
provided in subsection (b), or remitted by the Borrower to the Agent as provided
in Section 2.12, as the case may be.

         (d)      Unless the Agent shall have received notice from a Bank prior
to the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsections (b) and (c) of this Section 2.4 and the Agent may,
in reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Agent, such Bank and the Borrower severally agree to
repay to the Agent forthwith on demand such corresponding amount together with
interest thereon, for each day from the date such amount is made available to
the Borrower until the date such amount is repaid to the Agent, at (i) in the
case of the Borrower, a rate per annum equal to the higher of the Federal Funds
Rate and the interest rate applicable thereto pursuant to Section 2.7 and (ii)
in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to
the Agent such corresponding amount, such amount so repaid shall constitute such
Bank's Loan included in such Borrowing for purposes of this Agreement.

         SECTION 2.5. NOTES. (a) The Loans of each Bank shall be evidenced by a
single Note payable to the order of such Bank for the account of its Applicable
Lending Office in an amount equal to the aggregate unpaid principal amount of
such Bank's Loans.

         (b)      Each Bank may, by notice to the Borrower and the Agent,
request that its Loans of a particular type be evidenced by a separate Note in
an amount equal to the aggregate unpaid principal amount of such Loans. Each
such Note shall be in substantially the form of Exhibit A hereto with
appropriate modifications to reflect the fact that it evidences solely Loans of
the relevant type. Each reference in this Agreement to the "Note" of such Bank
shall be deemed to refer to and include any or all of such Notes, as the context
may require.

         (c)      Upon receipt of each Bank's Note pursuant to Section 3.1(d),
the Agent shall forward such Note to such Bank. Each Bank shall record the date,
amount, type and maturity of each Loan made by it and the date and amount of
each payment of principal made by the Borrower with respect thereto, and may, if
such Bank so elects in connection with any transfer or enforcement of its Note,
endorse on the schedule forming a part thereof appropriate notations to evidence
the foregoing information with respect to each such Loan then outstanding;
PROVIDED that the failure of any Bank to make any such recordation or
endorsement shall not affect the obligations of the Borrower hereunder or under
the Notes. Each Bank is hereby irrevocably authorized by the Borrower so to
endorse its Note and to attach to and make a part of its Note a continuation of
any such schedule as and when required.

                                      -19-

         SECTION 2.6. MATURITY OF LOANS. Each Loan included in any Borrowing
shall mature, and the principal amount thereof shall be due and payable, on the
last day of the Interest Period applicable to such Borrowing.

         SECTION 2.7. INTEREST RATES. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for such day. Such interest shall be payable for each Interest Period on
the last day thereof. Any overdue principal of or interest on any Base Rate Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the sum of 2% plus the rate otherwise applicable to Base Rate
Loans for such day.

         (b)      Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for the Interest Period applicable thereto, at a rate
per annum equal to the sum of the Euro-Dollar Margin plus the applicable London
Interbank Offered Rate. Such interest shall be payable for each Interest Period
on the last day thereof and, if such Interest Period is longer than three
months, at intervals of three months after the first day thereof.

         "Euro-Dollar Margin" means, for any day, the percentage per annum equal
to the applicable Euro-Dollar Margin set forth in the table below.

If the Investment                                       The Euro-Dollar
 Level Status is                                           Margin is
-----------------                                       ---------------

Investment Level Status I                                 .40 of 1%
Investment Level Status II                               .475 of 1%
Investment Level Status III                               .70 of 1%
Investment Level Status IV                               .925 of 1%
Investment Level Status V                               1.075 of 1%

         The "London Interbank Offered Rate" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
each of the Euro-Dollar Reference Banks in the London Interbank market at
approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Loan of such Euro-Dollar Reference Bank to
which such Interest Period is to apply and for a period of time comparable to
such Interest Period.

         (c)      Any overdue principal of or interest on any Euro-Dollar Loan
shall bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the sum of 2% plus the higher of (i) the sum of the
Euro-Dollar Margin plus the London Interbank Offered Rate applicable to such
Loan and (ii) the Euro-Dollar Margin plus the average (rounded upward, if
necessary, to the next higher 1/16 of 1%) of the respective rates per annum at
which one day (or, if such amount due remains unpaid more than three Euro-Dollar
Business Days, then for such other period of time not longer than three months
as the Agent may select) deposits in dollars in an amount approximately equal to
such overdue payment due to each of the

<PAGE>
                                      -20-

Euro-Dollar Reference Banks are offered to such Euro-Dollar Reference Bank in
the London interbank market for the applicable period determined as provided
above (or, if the circumstances described in clause (a) or (b) of Section 8.1
shall exist, at a rate per annum equal to the sum of 2% plus the rate applicable
to Base Rate Loans for such day (excluding the application of the last sentence
in Section 2.7 (a)).

         (d)      Subject to Section 8.1, each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the sum of the London
Interbank Offered Rate for such Interest Period (determined in accordance with
Section 2.7(c) as if the related Money Market LIBOR Borrowing were a Committed
Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the
Bank making such Loan in accordance with Section 2.3. Each Money Market Absolute
Rate Loan shall bear interest on the outstanding principal amount thereof, for
the Interest Period applicable thereto, at a rate per annum equal to the Money
Market Absolute Rate quoted by the Bank making such Loan in accordance with
Section 2.3. Such interest shall be payable for each Interest Period on the last
day thereof and, if such Interest Period is longer than three months, at
intervals of three months after the first day thereof. Any overdue principal of
or interest on any Money Market Loan shall bear interest, payable on demand, for
each day until paid at a rate per annum equal to the sum of 2% plus the Base
Rate for such day.

         (e)      The Agent shall determine each interest rate applicable to the
Loans hereunder. The Agent shall give prompt notice to the Borrower and the
participating Banks by telex or cable of each rate of interest so determined,
and its determination thereof shall be conclusive in the absence of manifest
error; provided that the Borrower shall, for a period of 60 days after such
notice is given, have the right to demonstrate that the rate of interest so
determined was not calculated in accordance with the terms of this Agreement;
provided further that until the fact that the rate of interest was not
calculated in accordance with the terms of this Agreement is demonstrated to the
satisfaction of the Agent (which must act reasonably and in good faith), the
Borrower shall continue to pay interest in accordance with the notice given.

         (f)      Each Euro-Dollar Reference Bank agrees to use its best efforts
to furnish quotations to the Agent as contemplated by this Section. If any
Reference Bank does not furnish a timely quotation, the Agent shall determine
the relevant interest rate on the basis of the quotation or quotations furnished
by the remaining Euro-Dollar Reference Bank or Banks or, if none of such
quotations is available on a timely basis, the provisions of Section 8.1 shall
apply.

         (g)      If for any reason any Euro-Dollar Reference Bank ceases to be
a Bank, the Agent with the written consent of the Borrower, which consent shall
not be unreasonably withheld, shall appoint a successor Euro-Dollar Reference
Bank which shall be one of the Banks.

         SECTION 2.8.  FEES.

         (a)      FACILITY FEE. The Borrower shall pay to the Agent for the
account of the Banks ratably a facility fee at the Facility Fee Rate per annum.
Such facility fee shall accrue for each day (i) from and including the Effective
Date to but excluding the Termination Date, on the aggregate amount of the
Commitments (whether used or unused) for such day and (ii) from and including
the Termination Date to but excluding the date the Loans shall be repaid in
their

<PAGE>
                                      -21-

entirety, on the daily average aggregate outstanding principal amount of the
Loans on such day.

         (b)      UTILIZATION FEE. The Borrower shall pay to the Agent for the
account of the Banks ratably, during any calendar quarter during the period from
the Effective Date to but excluding the Termination Date when the aggregate
daily average amount of outstanding Loans exceeds 33 1/3% of the aggregate
Commitments of the Banks, a utilization fee on the daily average amount of
outstanding Loans during such quarter at a rate equal to .125% per annum.

         (c)      PAYMENTS. Accrued fees under this Section shall be payable
quarterly in arrears on each March 31, June 30, September 30 and December 31 and
upon the date of termination of the Commitments in their entirety (and, if
later, the date the Loans shall be repaid in their entirety).

         SECTION 2.9. OPTIONAL TERMINATION OR REDUCTION OF COMMITMENTS. During
the Revolving Credit Period, the Borrower may, upon at least one Domestic
Business Day's notice to the Agent, (i) terminate the Commitments at any time,
if no Loans are outstanding at such time or (ii) ratably reduce from time to
time by an aggregate amount of $25,000,000 or a larger integral multiple of
$5,000,000 in excess thereof, the aggregate amount of the Commitments in excess
of the aggregate outstanding principal amount of the Loans. If the Commitments
are reduced or terminated pursuant to this Section, such Commitments may not be
increased or reinstated thereafter.

         SECTION 2.10. MANDATORY TERMINATION OF COMMITMENTS. The Commitments
shall terminate on the Termination Date, and any Loans then outstanding
(together with accrued interest thereon and any Facility Fees or other amounts
owing hereunder) shall be due and payable on such date, and the Borrower
promises to pay on the Termination Date, all such Loans outstanding on such
date, together with any and all accrued and unpaid interest thereon and any and
all other amounts due hereunder.

         SECTION 2.11. OPTIONAL PREPAYMENTS. (a) The Borrower may, upon same day
notice (no later than 10:00 A.M. Boston time) to the Agent, prepay any Base Rate
Borrowing (or any Money Market LIBOR Borrowing bearing interest at the Base Rate
pursuant to Section 8.1(a)) in whole at any time, or from time to time in part
in amounts aggregating $10,000,000 or any larger integral multiple of
$1,000,000, by paying the principal amount to be prepaid together with accrued
interest thereon to the date of prepayment. Each such optional prepayment shall
be applied to prepay ratably the Loans of the several Banks included in such
Borrowing.

         (b)      The Borrower may, upon at least three Domestic Business Days'
notice to the Agent, in the case of a Money Market Absolute Rate Borrowing, or
upon at least three Euro-Dollar Business Days' notice to the Agent, in the case
of a Euro-Dollar Borrowing or a Money Market LIBOR Borrowing (other than a Money
Market LIBOR Borrowing bearing interest at the Base Rate pursuant to Section
8.1(a)), subject to the provisions of Section 2.13, prepay any such Borrowing in
whole or in part in amounts aggregating $10,000,000 or any larger integral
multiple of $1,000,000, on any Domestic Business Day, in the case of a Money
Market Absolute Rate Borrowing, or any Euro-Dollar Business Day, in the case of
a Euro-Dollar Borrowing or a Money Market LIBOR Borrowing, by paying the
principal amount to be prepaid

<PAGE>
                                      -22-

together with accrued interest thereon to the date of prepayment. Each such
prepayment shall be applied to prepay ratably the outstanding Euro-Dollar Loans
or Money Market Loans of the several Banks included in such Borrowing, subject
to Article VIII.

         (c)      Upon receipt of a notice of prepayment pursuant to this
Section, the Agent shall promptly notify each Bank of the contents thereof and
of such Bank's ratable share (if any) of such prepayment and such notice shall
not thereafter be revocable by the Borrower.

         SECTION 2.12. GENERAL PROVISIONS AS TO PAYMENTS. (a) The Borrower shall
make each payment of principal of, and interest on, the Loans, payments of
Reimbursement Obligations and of fees and other amounts due hereunder, not later
than 12:00 Noon (Boston time) on the date when due, in U.S. Dollars and in
immediately available funds in Boston, to the Agent at the Agent's Office. The
Agent will promptly distribute to each Bank its ratable share of each such
payment received by the Agent for the account of the Banks. Whenever any payment
of principal of, or interest on, the Domestic Loans, payments of Reimbursement
Obligations or of fees shall be due on a day which is not a Domestic Business
Day, the date for payment thereof shall be extended to the next succeeding
Domestic Business Day. Whenever any payment of principal of, or interest on, the
Euro-Dollar Loans or the Money Market LIBOR Loans shall be due on a day which is
not a Euro-Dollar Business Day, the date for payment thereof shall be extended
to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business
Day falls in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Dollar Business Day. Whenever any payment of
principal of, or interest on, the Money Market Absolute Rate Loans shall be due
on a day which is not a Euro-Dollar Business Day, the date for payment thereof
shall be extended to the next succeeding Euro-Dollar Business Day. If the date
for any payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

         (b)      Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Banks hereunder that the
Borrower will not make such payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each Bank on
such due date an amount equal to the amount then due such Bank. If and to the
extent that the Borrower shall not have so made such payment, each Bank shall
repay to the Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Agent, at the Federal Funds Rate.

         SECTION 2.13. FUNDING LOSSES. If the Borrower makes any payment of
principal with respect to any Euro-Dollar Loans or Money Market Loans (pursuant
to Section 2.11(b), Article VI or VIII or otherwise) on any day other than the
last day of the Interest Period applicable thereto, or the end of an applicable
period fixed pursuant to Section 2.7(d), or if the Borrower fails to borrow any
Euro-Dollar Loans or Money Market Loans after notice has been given to any Bank
in accordance with Section 2.4(a), the Borrower shall reimburse each Bank within
15 days after demand for any resulting loss or expense incurred by it (or by an
existing or prospective Participant in the related Loan), including (without
limitation) any loss incurred in obtaining, liquidating or employing deposits
from third parties, but excluding loss of margin for the period after any such
payment or failure to borrow, PROVIDED that such Bank shall have

<PAGE>
                                      -23-

delivered to the Borrower a certificate as to the amount of such loss or
expense, which certificate shall be conclusive in the absence of manifest error,
PROVIDED that the Borrower shall have the right, within 60 days of receipt of
such certificate, to demonstrate that the amount set forth in such certificate
is incorrect and request an adjustment of the amount to be, or theretofore,
paid.

         SECTION 2.14. COMPUTATION OF INTEREST AND FEES. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

         SECTION 2.15. TAXES. (a) Any and all payments by the Borrower to or for
the account of any Bank or the Agent hereunder or under any Note, Letter of
Credit or Letter of Credit Application shall be made free and clear of and
without deduction for any and all present or future taxes, duties, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, EXCLUDING, (1) in the case of each Bank and the Agent, taxes imposed on
its income, and franchise or similar taxes imposed on it, by the jurisdiction
under the laws of which such Bank or the Agent (as the case may be) is
organized, (2) in the case of each Bank, taxes imposed on its income, and
franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office and (3) in the case of each Bank, taxes imposed on its
net income and franchise taxes which such Bank or Agent is subject to at the
time the Bank first becomes a party to this Agreement, at whatever rates may be
in effect for such taxes from time to time (all such non-excluded taxes, duties,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder or under any
Note, Letter of Credit or Letter of Credit Application to any Bank or the Agent,
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.15) such Bank or the Agent (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law and (iv) the Borrower shall furnish to the Agent,
at its address referred to in Section 9.1, the original or a certified copy of a
receipt evidencing payment thereof.

         (b)      In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise solely from any payment made hereunder or under any
Note, Letter of Credit or Letter of Credit Application or from the execution or
delivery of, or otherwise with respect to, this Agreement or any Note, Letter of
Credit or Letter of Credit Application (hereinafter referred to as "Other
Taxes").

         (c)      The Borrower agrees to indemnify each Bank and the Agent for
the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.15) paid by such Bank or the Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto. This indemnification shall be made within 15 days from the date
such Bank or the Agent (as the case may be) makes demand therefor; PROVIDED,
HOWEVER, that (1)

<PAGE>
                                      -24-

after the Borrower has made a payment pursuant to this provision, the Borrower
shall not be obligated to pay any further penalties, interest or expenses
accrued thereafter imposed by a jurisdiction with respect to such Taxes or Other
Taxes to which the payment is related and (2) if the Bank knows or has reason to
know of the imposition of any Taxes or Other Taxes for which the Borrower is
required to indemnify such Bank under this Section 2.15 and fails to promptly
notify the Borrower of such imposition, the Borrower shall not be obligated to
pay any penalties, interest or expenses accrued with respect to such Taxes or
Other Taxes after the Bank has such knowledge and before the Borrower has
received such notification.

         (d)      Each Bank organized under the laws of a jurisdiction outside
the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
and from time to time thereafter if requested in writing by the Borrower (but
only so long as such Bank remains lawfully able to do so), shall provide the
Borrower with Internal Revenue Service Form W-8BEN or W-8EC1, as appropriate, or
any successor form prescribed by the Internal Revenue Service, certifying that
such Bank is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States. If the form provided by a Bank at the time such Bank first becomes a
party to this Agreement indicates a United States interest withholding tax rate
in excess of zero, withholding tax at such rate shall be considered excluded
from "Taxes" as defined in Section 2.15(a).

         (e)      For any period with respect to which a Bank has failed to
provide the Borrower with the appropriate form pursuant to Section 2.15(d)
(unless such failure is due to a change in treaty, law or regulation occurring
subsequent to the date on which a form originally was required to be provided),
such Bank shall not be entitled to indemnification under Section 2.15(a) with
respect to Taxes imposed by the United States; PROVIDED, HOWEVER, that should a
Bank, which is otherwise exempt from or subject to a reduced rate of withholding
tax, become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Bank shall reasonably
request to assist such Bank to recover such Taxes.

         (f)      If the Borrower is required to pay additional amounts to or
for the account of any Bank pursuant to this Section 2.15, then such Bank will
change the jurisdiction of its Applicable Lending Office so as to eliminate or
reduce any such additional payment which may thereafter accrue if such change,
in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

         (g)      Upon a reasonable request of the Borrower, a Bank shall, at
the expense of the Borrower, seek the refund for any Taxes or Other Taxes for
which the Borrower has indemnified the Bank under this Section 2.15, PROVIDED
that such Bank, in its sole discretion, determines that the application of such
refund will not be detrimental to such Bank.

         SECTION 2.16. REGULATION D COMPENSATION. Each Bank may require the
Borrower to pay, contemporaneously with each payment of interest on the related
Euro-Dollar Loans, additional interest on the related Euro-Dollar Loans of such
Bank at a rate per annum determined by such Bank up to but not exceeding the
excess of (i) (A) the applicable London

<PAGE>
                                      -25-

Interbank Offered Rate divided by (B) one MINUS the Euro-Dollar Reserve
Percentage over (ii) the applicable London Interbank Offered Rate. Any Bank
wishing to require payment of such additional interest (x) shall so notify the
Borrower and the Agent in writing no later than two Euro-Dollar Business Days
before the making of any Euro-Dollar Loans hereunder, in which case such
additional interest on the Euro-Dollar Loans of such Bank shall be payable to
such Bank at the place indicated in such notice with respect to each Interest
Period commencing at least three Euro-Dollar Business Days after the giving of
such notice and (y) shall notify the Borrower at least five Euro-Dollar Business
Days prior to each date on which interest is payable on the Euro-Dollar Loans of
the amount then due it under this Section.

         SECTION 2.17.  LETTERS OF CREDIT.

                  SECTION 2.17.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject
         to the terms and conditions hereof and the execution and delivery by
         the Borrower of a letter of credit application on the Agent's customary
         form (a "Letter of Credit Application"), the Agent on behalf of the
         Banks and in reliance upon the agreement of the Banks set forth in
         Section 2.17.4 and upon the representations and warranties of the
         Borrower contained herein, agrees, in its individual capacity, to
         issue, extend and renew for the account of the Borrower one or more
         standby or documentary letters of credit (individually, a "Letter of
         Credit"), in such form as may be requested from time to time by the
         Borrower and agreed to by the Agent; PROVIDED, HOWEVER, that, after
         giving effect to such request, (a) the sum of the aggregate Maximum
         Drawing Amount and all Unpaid Reimbursement Obligations shall not
         exceed $25,000,000 at any one time and (b) the sum of (i) the Maximum
         Drawing Amount on all Letters of Credit, (ii) all Unpaid Reimbursement
         Obligations, and (iii) the amount of all Loans outstanding shall not
         exceed the Total Commitment. Notwithstanding the foregoing, the Agent
         shall have no obligation to issue any Letter of Credit to support or
         secure any Indebtedness of the Borrower or any of its Subsidiaries to
         the extent that such Indebtedness was incurred prior to the proposed
         issuance date of such Letter of Credit, unless in any such case the
         Borrower demonstrates to the satisfaction of the Agent that (x) such
         prior incurred Indebtedness was then fully secured by a prior perfected
         and unavoidable security interest in collateral provided by the
         Borrower or such Subsidiary to the proposed beneficiary of such Letter
         of Credit or (y) such prior incurred Indebtedness was then secured or
         supported by a letter of credit issued for the account of the Borrower
         or such Subsidiary and the reimbursement obligation with respect to
         such letter of credit was fully secured by a prior perfected and
         unavoidable security interest in collateral provided to the issuer of
         such letter of credit by the Borrower or such Subsidiary.

                  SECTION 2.17.2. LETTER OF CREDIT APPLICATIONS. Each Letter of
         Credit Application shall be completed to the satisfaction of the Agent.
         In the event that any provision of any Letter of Credit Application
         shall be inconsistent with any provision of this Credit Agreement, then
         the provisions of this Credit Agreement shall, to the extent of any
         such inconsistency, govern.

                  SECTION 2.17.3. TERMS OF LETTERS OF CREDIT. Each Letter of
         Credit issued, extended or renewed hereunder shall, among other things,
         (a) provide for the payment of sight drafts for honor thereunder when
         presented in accordance with the terms

<PAGE>
                                      -26-

         thereof and when accompanied by the documents described therein, and
         (b) have an expiry date no later than the date which is fourteen (14)
         days (or, if the Letter of Credit is confirmed by a confirmer or
         otherwise provides for one or more nominated persons, forty-five (45)
         days) prior to the Termination Date. Each Letter of Credit so issued,
         extended or renewed shall be subject to the Uniform Customs or, in the
         case of a standby Letter of Credit, either the Uniform Customs or the
         International Standby Practices (ISP98), International Chamber of
         Commerce Publication No. 590, or any successor code of standby letter
         of credit practices among banks, adopted by the Agent in the ordinary
         course of its business as a standby letter of credit issuer and in
         effect at the time of issuance of such Letter of Credit.

                  SECTION 2.17.4. REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank
         severally agrees that it shall be absolutely liable, without regard to
         the occurrence of any Default or Event of Default or any other
         condition precedent whatsoever, to the extent of such Bank's Commitment
         Percentage, to reimburse the Agent on demand for the amount of each
         draft paid by the Agent under each Letter of Credit to the extent that
         such amount is not reimbursed by the Borrower pursuant to Section 2.18
         (such agreement for a Bank being called herein the "Letter of Credit
         Participation" of such Bank).

                  SECTION 2.17.5. PARTICIPATIONS OF BANKS. Each such payment
         made by a Bank shall be treated as the purchase by such Bank of a
         participating interest in the Borrower's Reimbursement Obligation under
         Section 2.18 in an amount equal to such payment. Each Bank shall share
         in accordance with its participating interest in any interest which
         accrues pursuant to Section 2.18.

         SECTION 2.18. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to
induce the Agent to issue, extend and renew each Letter of Credit and the Banks
to participate therein, the Borrower hereby agrees to reimburse or pay to the
Agent, for the account of the Agent or (as the case may be) the Banks, with
respect to each Letter of Credit issued, extended or renewed by the Agent
hereunder,

         (a)      except as otherwise expressly provided in Section 2.18(b) and
(c), on each date that any draft presented under such Letter of Credit is
honored by the Agent, or the Agent otherwise makes a payment with respect
thereto, (i) the amount paid by the Agent under or with respect to such Letter
of Credit, and (ii) the amount of any taxes, fees, charges or other reasonable
costs and expenses whatsoever incurred by the Agent or any Bank in connection
with any payment made by the Agent or any Bank under, or with respect to, such
Letter of Credit,

         (b)      upon the reduction (but not termination) of the Total
Commitment to an amount less than the Maximum Drawing Amount, an amount equal to
such difference, which amount shall be held by the Agent for the benefit of the
Banks and the Agent as cash collateral for all Reimbursement Obligations, and

         (c)      upon the termination of the Total Commitment, or the
acceleration of the Reimbursement Obligations with respect to all Letters of
Credit in accordance with Article VI, an amount equal to the then Maximum
Drawing Amount on all Letters of Credit, which

<PAGE>
                                      -27-

amount shall be held by the Agent for the benefit of the Banks and the Agent as
cash collateral for all Reimbursement Obligations.

         Each such payment shall be made to the Agent at the Agent's Office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrower under this Section 2.18 at any time from the date such amounts
become due and payable (whether as stated in this Section 2.18, by acceleration
or otherwise) until payment in full (whether before or after judgment) shall be
payable to the Agent on demand at the rate specified in Section 2.7 for overdue
principal on the Loans.

         SECTION 2.19. LETTER OF CREDIT PAYMENTS. If any draft shall be
presented or other demand for payment shall be made under any Letter of Credit,
the Agent shall notify the Borrower of the date and amount of the draft
presented or demand for payment and of the date and time when it expects to pay
such draft or honor such demand for payment. If the Borrower fails to reimburse
the Agent as provided in Section 2.18 on or before the date that such draft is
paid or other payment is made by the Agent, the Agent may at any time thereafter
notify the Banks of the amount of any such Unpaid Reimbursement Obligation. No
later than 3:00 p.m. (Boston time) on the Domestic Business Day next following
the receipt of such notice, each Bank shall make available to the Agent, at the
Agent's Office, in immediately available funds, such Bank's Commitment
Percentage of such Unpaid Reimbursement Obligation, together with an amount
equal to the product of (a) the average, computed for the period referred to in
clause (c) below, of the weighted average interest rate paid by the Agent for
federal funds acquired by the Agent during each day included in such period,
TIMES (b) the amount equal to such Bank's Commitment Percentage of such Unpaid
Reimbursement Obligation, TIMES (c) a fraction, the numerator of which is the
number of days that elapse from and including the date the Agent paid the draft
presented for honor or otherwise made payment to the date on which such Bank's
Commitment Percentage of such Unpaid Reimbursement obligation shall become
immediately available to the Agent, and the denominator of which is 360. The
responsibility of the Agent to the Borrower and the Banks shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity in all
material respects with such Letter of Credit.

         SECTION 2.20. OBLIGATIONS ABSOLUTE. The Borrower's obligations under
this Section 2.17-2.22 shall be absolute and unconditional under any and all
circumstances and irrespective of the occurrence of any Default or Event of
Default or any condition precedent whatsoever or any setoff, counterclaim or
defense to payment which the Borrower may have or have had against the Agent,
any Bank or any beneficiary of a Letter of Credit. The Borrower further agrees
with the Agent and the Banks that the Agent and the Banks shall not be
responsible for, and the Borrower's Reimbursement Obligations under Section 2.18
shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even if such documents should in fact
prove to be in any or all respects invalid, fraudulent or forged, or any dispute
between or among the Borrower, the beneficiary of any Letter of Credit or any
financing institution or other party to which any Letter of Credit may be
transferred or any claims or defenses whatsoever of the Borrower against the
beneficiary of any Letter of Credit or any such transferee. The Agent and the
Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any

<PAGE>
                                      -28-

message or advice, however transmitted, in connection with any Letter of Credit.
The Borrower agrees that any action taken or omitted by the Agent or any Bank
under or in connection with each Letter of Credit and the related drafts and
documents, if done in good faith, shall be binding upon the Borrower and shall
not result in any liability on the part of the Agent or any Bank to the
Borrower.

         SECTION 2.21. RELIANCE BY ISSUER. To the extent not inconsistent with
Section 2.20, the Agent shall be entitled to rely, and shall be fully protected
in relying upon, any Letter of Credit, draft, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent. The Agent shall be fully
justified in failing or refusing to take any action under this Credit Agreement
unless it shall first have received such advice or concurrence of the Required
Banks as it reasonably deems appropriate or it shall first be indemnified to its
reasonable satisfaction by the Banks against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take any such
action. The Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Credit Agreement in accordance with a request
of the Required Banks, and such request and any action taken or failure to act
pursuant thereto shall be binding upon the Banks and all future holders of the
Notes or of a Letter of Credit Participation.

         SECTION 2.22. LETTER OF CREDIT FEE. The Borrower shall pay a fee (in
each case, a "Letter of Credit Fee") to the Agent in respect of each Letter of
Credit, calculated at an amount equal to the Euro-Dollar Margin then in effect
for Euro-Dollar Borrowings times the aggregate face amount of such Letter of
Credit, PLUS, a fee equal to one-eighth of one percent (1/8%) per annum of the
face amount of such Letter of Credit (the "Fronting Fee"), which Fronting Fee
shall be for the account of the Agent, as a fronting fee, and the balance of
which Letter of Credit Fee shall be for the accounts of the Banks in accordance
with their respective Commitment Percentages. The Letter of Credit Fee and the
Fronting Fee shall be payable quarterly in arrears on the last Business Day of
each calendar quarter for the calendar quarter then ending. In respect of each
Letter of Credit, the Borrower shall also pay to the Agent for the Agent's own
account, at such other time or times as such charges are customarily made by the
Agent, the Agent's customary issuance, amendment, negotiation or document
examination and other administrative fees as in effect from time to time.

                                  ARTICLE III.

                                   CONDITIONS

on any party hereto unless all of the foregoing conditions are satisfied not

Banks of the Effective Date, and such notice shall be conclusive and binding on
all parties hereto. The Banks that are parties to the Existing Credit Agreement,
comprising the "Required Banks" as defined therein, and the Borrower agree that
the commitments under the Existing Credit Agreement shall terminate in their
entirety simultaneously with and subject to the effectiveness of this Agreement
and that the Borrower shall be obligated to pay the accrued facility fees
thereunder to but excluding the date of such effectiveness.

the occasion of any Borrowing, or of the Agent to issue, extend or renew any
Letter of Credit, is subject to the satisfaction of the following conditions:

of such Borrowing or such issuance, extension or renewal of such Letter of
Credit.

         Each Borrowing or request for the issuance, extension or renewal of any
Letter of Credit hereunder shall be deemed to be a representation and warranty
by the Borrower on the date of such Borrowing as to the facts specified in
clauses (b), (c) and (d) of this Section.

                                   ARTICLE IV.

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Agent and each of the Banks
that:

         SECTION 4.1. CORPORATE EXISTENCE AND POWER. The Borrower is a
corporation duly incorporated, validly existing and in good standing under the
laws of Delaware, and has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted.

         SECTION 4.2. CORPORATE AND GOVERNMENTAL AUTHORIZATION; NO
CONTRAVENTION. The execution, delivery and performance by the Borrower of this

instrument to which it may be subject or by which it or any of its properties
may be bound or any decree, order, judgment, statute, law, license, rule or
regulation, in any of the foregoing cases in a manner that could result in the
imposition of substantial penalties or have a material adverse effect on the
business, assets or financial condition of the Borrower.

         SECTION 4.3. BINDING EFFECT. This Agreement constitutes a valid and
binding agreement of the Borrower and the Notes and other Loan Documents, when
executed and delivered in accordance with this Agreement, will constitute valid
and binding obligations of the Borrower.

         (a)      The consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries as of September 30, 2000, and the related consolidated
statements of income, cash flows and stockholders' equity for the fiscal year
then ended, reported on by PricewaterhouseCoopers LLP and set forth in the
Borrower's 2000 Form 10-K, a copy of which has been delivered to each of the
Banks, fairly present, in conformity with generally accepted accounting
principles, the consolidated financial position of the Borrower and its
Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such fiscal year.

         (b)      Since September 30, 2000, there has been no material adverse
change in the business, financial position, results of operations or prospects
of the Borrower and its Consolidated Subsidiaries, considered as a whole.

         SECTION 4.5. LITIGATION. Except as described in the Borrower's 2000
Form 10-K, there is no action, suit or proceeding pending against, or to the
knowledge of the Borrower threatened against or affecting, the Borrower or any
of its Consolidated Subsidiaries before any court or arbitrator or any
governmental body, agency or official which poses a material risk of being
adversely determined and, if so determined, might reasonably be expected to
materially adversely affect the business; consolidated financial position or
consolidated results of operations of the Borrower and its Consolidated
Subsidiaries considered as a whole or which in any manner draws into question
the validity of this Agreement or the other Loan Documents.

         SECTION 4.6. COMPLIANCE WITH ERISA. Each member of the ERISA Group has
fulfilled its obligations under the minimum funding standards of ERISA and the
Internal Revenue Code with respect to each Plan and is in compliance in all
respects material to the Borrower and its Consolidated Subsidiaries considered
as a whole with the presently applicable provisions of ERISA and the Internal
Revenue Code with respect to each Plan. No member of the ERISA Group has within
the past five years (i) sought a waiver of the minimum funding standard under
Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to
make any contribution or payment to any Plan or Multiemployer Plan, or made any
amendment to any Plan which has resulted or could reasonably be expected to
result in the imposition of a Lien under Section 302 (f) of ERISA, Section
412(n) of the Internal Revenue Code or any successor provision thereto or the
posting of a bond or other security under Section 307 of ERISA, Section
401(a)(29) of the Internal Revenue Code or any successor provision thereto in
excess of $20,000,000 or (iii) incurred any liability in excess of $10,000,000
under Title IV of ERISA other than a liability to the PBGC for premiums under
Section 4007 of ERISA.

         SECTION 4.7. ENVIRONMENTAL MATTERS. In the ordinary course of its
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Consolidated Subsidiaries, in the course of which, taking into account the
requirements of such Environmental Laws, it makes a reasonable effort to
identify and evaluate known and potential associated liabilities and costs
(including, without limitation, any capital or operating expenditures required
for clean-up or closure of properties presently or previously owned, any capital
or operating expenditures required to achieve or maintain compliance with
Environmental Laws or as a condition of any license, permit or contract held or
entered into by the Borrower or any Consolidated Subsidiary, any related
constraints on operating activities, including any periodic or permanent
shutdown of any facility or reduction in the level of or change in the nature of
operations conducted thereat and any actual or potential material liabilities to
third parties, including employees of the Borrower and its Consolidated
Subsidiaries and any related costs and expenses). On the basis of this review,
the Borrower has reasonably concluded that such liabilities and costs, including
the cost of compliance with and liabilities arising under Environmental Laws,
are unlikely to have a material adverse effect on the business, financial
condition, results of operations or prospects of the Borrower and its
Consolidated Subsidiaries, considered as a whole.

         SECTION 4.8. TAXES. United States Federal income tax returns of the
Borrower and its Consolidated Subsidiaries have been examined and closed through
the fiscal year ended September 30, 1996. The Borrower and its Consolidated
Subsidiaries have filed all United States Federal income tax returns and all
other material tax returns which are required to be filed by them and have paid
all taxes due pursuant to such returns or pursuant to any assessment received by
the Borrower or any Subsidiary, except such taxes or assessments, if any, as are
being contested in good faith by appropriate proceedings or where the failure to
do so does not materially adversely affect the Borrower and its Consolidated
Subsidiaries, considered as a whole. The charges, accruals and reserves on the
books of the Borrower and its Consolidated Subsidiaries in respect of taxes or
other governmental charges are, in the opinion of the Borrower, adequate.

         SECTION 4.9. SUBSIDIARIES. Each of the Borrower's Subsidiaries which is
organized as a corporation is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of 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 4.10. NOT AN INVESTMENT COMPANY. The Borrower is not an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

         SECTION 4.11. FULL DISCLOSURE. All information heretofore furnished by
the Borrower to the Agent or any Bank for purposes of or in connection with this
Agreement or any transaction contemplated hereby is, and all such information
hereafter furnished by the Borrower to the Agent or any Bank will be, true and
accurate in all material respects on the date as of which such information is
stated or certified. The Borrower has disclosed to the Banks in writing any and
all facts known to the Borrower's management which materially and adversely

business, operations or financial condition of the Borrower and its Consolidated
Subsidiaries, taken as a whole, or the ability of the Borrower to perform its
obligations under this Agreement.

their debts under any bankruptcy, insolvency or other similar law now or
hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of it or them or any substantial
part of its or their property, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case
or other proceeding commenced against it or them, or shall make a general
assignment for the benefit of creditors, or shall fail generally to pay its or
their debts as they become due, or shall take any corporate action to authorize
any of the foregoing;

         (h)      an involuntary case or other proceeding shall be commenced
against the Borrower or any Subsidiary or Subsidiaries in which the Borrower's
aggregate direct and indirect Investment is at least $20,000,000 seeking
liquidation, reorganization or other relief with respect to it or them or its or
their debts under any bankruptcy, insolvency or other similar law now or
hereafter in effect or seeking the appointment of a trustee, receiver,

         (i)      any member of the ERISA Group shall fail to pay when due an

<PAGE>
                                      -41-

with respect to, one or more Multiemployer Plans which could cause one or more
members of the ERISA Group to incur a current payment obligation in excess of
$25,000,000;

         (j)      a judgment or order for the payment of money in excess of
$20,000,000 shall be rendered against the Borrower or any Subsidiary and such
judgment or order shall continue unsatisfied and unstayed for a period of 10
days; or

         (k)      any person or group of persons (within the meaning of Section
13 of the Securities Exchange Act of 1934, as amended), other than members of
the Cabot family or Persons holding securities for the benefit of members of the

the Borrower terminate the Commitments and they shall thereupon terminate and
the Agent shall be relieved of all further obligations to issue, extend or renew
Letters of Credit, and (ii) if requested by Banks holding Notes evidencing more
than 50% in aggregate principal amount of the Loans by notice to the Borrower
declare all amounts owing with respect to this Agreement, the Notes (together
with accrued interest thereon) and the other Loan Documents and all
Reimbursement Obligations to be, and they shall thereupon become, immediately
due and payable without presentment, demand, protest or other notice of any
kind, all of which are hereby expressly waived by the Borrower; PROVIDED that in
the case of any of the Events of Default specified in clause (g) or (h) above
with respect to the Borrower, without any notice to the Borrower or any other
act by the Agent or the Banks, the Commitments shall thereupon terminate and the
Agent shall be relieved of all further obligations to issue, extend or renew
Letters of Credit shall become immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are hereby waived by
the Borrower.

         SECTION 6.2. NOTICE OF DEFAULT. The Agent shall give notice to the
Borrower under Section 6.1(c) promptly upon being requested to do so by any Bank
and shall thereupon notify all the Banks thereof.

         SECTION 6.3. REMEDIES. In case any one or more of the Events of Default
shall have occurred and be continuing, and whether or not the Banks shall have
accelerated the maturity of the Loans pursuant to Section 6.1, each Bank, if
owed any amount with respect to the Loans or the Reimbursement Obligations, may
proceed to protect and enforce its rights by suit in equity, action at law or
other appropriate proceeding, whether for the specific performance of any
covenant or agreement contained in this Agreement and the other Loan Documents
or any instrument pursuant to which the obligations to such Lender are
evidenced, including as permitted by applicable law the obtaining of the EX
PARTE appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Lender. No remedy herein conferred upon

<PAGE>
                                      -42-

any Bank or the Agent or the holder of any Note or purchaser of any Letter of
Credit Participation is intended to be exclusive of any other remedy and each
and every remedy shall be cumulative and shall be in addition to every other
remedy given hereunder or now or hereafter existing at law or in equity or by
statute or any other provision of law.

                                  ARTICLE VII.

                                   THE AGENT

         SECTION 7.1.  APPOINTMENT AND AUTHORIZATION.

         (a)      Each Bank irrevocably appoints and authorizes the Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement and the other Loan Documents as are delegated to the Agent by the
terms hereof or thereof, together with all such powers as are reasonably
incidental thereto PROVIDED that no duties or responsibilities not expressly
assumed herein or therein shall be implied to have been assumed by the Agent;

         (b)      The relationship between the Agent and each of the Banks is
that of an independent contractor. The use of the term "Agent" is for
convenience only and is used to describe, as a form of convention, the
independent contractual relationship between the Agent and each of the Banks.
Nothing contained in this Agreement nor the other Loan Documents shall be
construed to create an agency, trust or other fiduciary relationship between the
Agent and any of the Banks;

         (c)      As an independent contractor empowered by the Banks to
exercise certain rights and perform certain duties and responsibilities
hereunder and under the other Loan Documents, the Agent is nevertheless a
"representative" of the Banks, as that term is defined in Article 1 of the
Uniform Commercial Code, for purposes of actions for the benefit of the Banks
and the Agent with respect to any and all collateral security and guaranties
contemplated by the Loan Documents. Such actions include the designation of the
Agent as "SECURED PARTY", "MORTGAGEE" or the like on all financing statements
and other documents and instruments, whether recorded or otherwise, relating to
the attachment, perfection, priority or enforcement of any security interests,
mortgages or deeds of trust in collateral security intended to secure the
payment or performance of any of the obligations, all for the benefit of the
Banks and the Agent.

         SECTION 7.2. AGENT AND AFFILIATES. Fleet National Bank shall have the
same rights and powers under this Agreement as any other Bank and may exercise
or refrain from exercising the same as though it were not the Agent, and Fleet
National Bank and its affiliates may accept deposits from, lend money to, and
generally engage in any kind of business with the Borrower or any Subsidiary or
affiliate of the Borrower as if it were not the Agent hereunder.

         SECTION 7.3. ACTION BY AGENT. The obligations of the Agent hereunder
are only those expressly set forth herein. Without limiting the generality of
the foregoing, the Agent shall not

<PAGE>
                                      -43-

be required to take any action with respect to any Default, except as expressly
provided in Article VI.

         SECTION 7.4. CONSULTATION WITH EXPERTS. The Agent may consult with
legal counsel (who may be counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

         SECTION 7.5. LIABILITY OF AGENT. Neither the Agent nor any of its
affiliates nor any of their respective directors, officers, agents or employees
shall be liable for any action taken or not taken by it in connection herewith
(i) with the consent or at the request of the Required Banks or (ii) in the
absence of its own gross negligence or willful misconduct. Neither the Agent nor
any of its affiliates nor any of their respective directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
this Agreement or any borrowing hereunder; (ii) the performance or observance of
any of the covenants or agreements of the Borrower; (iii) the satisfaction of
any condition specified in Article III, except receipt of items required to be
delivered to the Agent; or (iv) the validity, effectiveness or genuineness of
this Agreement, the Notes or any other instrument or writing furnished in
connection herewith. The Agent shall not incur any liability by acting in
reliance upon any notice, consent, certificate, statement, or other writing
(which may be a bank wire, telex or similar writing) believed by it to be
genuine or to be signed by the proper party or parties.

         SECTION 7.6. INDEMNIFICATION. Each Bank shall, ratably in accordance
with its Commitment, indemnify the Agent, its affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the
Borrower) against any cost, expense (including counsel fees and disbursements),
claim, demand, action, loss or liability (except such as result from such
indemnitees' gross negligence or willful misconduct) that such indemnitees may
suffer or incur in connection with this Agreement or any action taken or omitted
by such indemnitees hereunder.

         SECTION 7.7. CREDIT DECISION. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Bank also
acknowledges that it will, independently and without reliance upon the Agent or
any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

         SECTION 7.8. SUCCESSOR AGENT. The Agent may resign at any time by
giving written notice thereof to the Banks and the Borrower. Upon any such
resignation, the Required Banks with the written consent of the Borrower, which
consent shall not be unreasonably withheld, shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Banks, and shall have accepted such appointment, within 30 days after
the retiring Agent gives notice of resignation, then the retiring Agent may, on
behalf of the

<PAGE>
                                      -44-

Banks, appoint a successor Agent, which shall be a commercial bank organized or
licensed under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $50,000,000. Upon the
acceptance of its appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the rights
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent.

         SECTION 7.9. AGENT'S FEE. The Borrower shall pay to the Agent for its
own account fees in the amounts and at the times set forth in the Fee Letter.

         SECTION 7.10. DELINQUENT BANK. Notwithstanding anything to the contrary
contained in this Agreement or any of the other Loan Documents, any Bank that
fails (a) to make available to the Agent its PRO RATA share of any Committed
Loan or to purchase any Letter of Credit Participation or (b) to comply with the
provisions of Section 9.4 with respect to making dispositions and arrangements
with the other Banks, where such Bank's share of any payment received, whether
by setoff or otherwise, is in excess of its PRO RATA share of such payments due
and payable to all of the Banks, in each case as, when and to the full extent
required by the provisions of this Agreement, shall be deemed delinquent (a
"DELINQUENT LENDER") and shall be deemed a Delinquent Lender until such time as
such delinquency is satisfied. A Delinquent Lender shall be deemed to have
assigned any and all payments due to it from the Borrower, whether on account of
outstanding Loans, Unpaid Reimbursement Obligations, interest, fees or
otherwise, to the remaining nondelinquent Banks for application to, and
reduction of, their respective PRO RATA shares of all outstanding Committed
Loans and Unpaid Reimbursement Obligations. The Delinquent Lender hereby
authorizes the Agent to distribute such payments to the nondelinquent Banks in
proportion to their respective PRO RATA shares of all outstanding Committed
Loans and Unpaid Reimbursement Obligations. A Delinquent Lender shall be deemed
to have satisfied in full a delinquency when and if, as a result of application
of the assigned payments to all outstanding Committed Loans and Unpaid
Reimbursement Obligations of the nondelinquent Banks, the Banks' respective PRO
RATA shares of all outstanding Committed Loans and Unpaid Reimbursement
Obligations have returned to those in effect immediately prior to such
delinquency and without giving effect to the nonpayment causing such
delinquency.

                                  ARTICLE VIII.

                             CHANGE IN CIRCUMSTANCES

         SECTION 8.1. BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR.
If on or prior to the first day of any Interest Period for any Borrowing
comprised of Euro-Dollar Loans or Money Market Loans:

         (a)      the Agent is advised by the Euro-Dollar Reference Banks that
deposits in dollars (in the applicable amounts) are not being offered to the
Euro-Dollar Reference Banks in the relevant market for such Interest Period, or

<PAGE>
                                      -45-

         (b)      in the case of a Committed Borrowing, Banks having 50% or more
of the aggregate amount of the Commitments advise the Agent that the London
Interbank Offered Rate as determined by the Agent will not adequately and fairly
reflect the cost to such Banks of funding their Euro-Dollar Loans for such
Interest Period, the Agent shall forthwith give notice thereof to the Borrower,
and the Banks, whereupon until the Agent notifies the Borrower that the
circumstances giving rise to such suspension no longer exist, the obligations of
the Banks to make Euro-Dollar Loans shall be suspended. Unless the Borrower
notifies the Agent at least two Domestic Business Days before the date of any
Borrowing of Euro-Dollar Loans or Money Market Loans for which a Notice of
Borrowing has previously been given that it elects not to borrow on such date,
(i) if such Borrowing of Euro-Dollar Loans or Money Market Loans is a Committed
Borrowing, such Borrowing shall instead be made as a Base Rate Borrowing and
(ii) if such Borrowing of Euro-Dollar Loans or Money Market Loans is a Money
Market LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing
shall bear interest for each day from and including the first day to but
excluding the last day of the Interest Period applicable thereto at the Base
Rate for such day.

         SECTION 8.2. ILLEGALITY. If, on or after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change therein,
or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Euro-Dollar Lending office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency shall
make it unlawful or impossible for any Bank (or its Euro-Dollar Lending office)
to make, maintain or fund its Euro-Dollar Loans and such Bank shall so notify
the Agent, the Agent shall forthwith give notice thereof to the other Banks and
the Borrower, whereupon until such Bank notifies the Borrower and the Agent that
the circumstances giving rise to such suspension no longer exist, the obligation
of such Bank to make Euro-Dollar Loans shall be suspended. Before giving any
notice to the Agent pursuant to this Section, such Bank shall designate a
different Euro-Dollar Lending Office if such designation will avoid the need for
giving such notice and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank. If such Bank shall determine that it may not
lawfully continue to maintain and fund any of its outstanding Euro-Dollar Loans
to maturity and shall so specify in such notice, the Borrower shall immediately
prepay in full the then outstanding principal amount of each such Euro-Dollar
Loan, together with accrued interest thereon. Concurrently with prepaying each
such Euro-Dollar Loan, the Borrower shall borrow a Base Rate Loan in an equal
principal amount from such Bank (on which interest and principal shall be
payable contemporaneously with the related Euro-Dollar Loans of the other
Banks), and such Bank shall make such a Base Rate Loan.

         SECTION 8.3. INCREASED COST AND REDUCED RETURN. (a) If on or after (x)
the date hereof, in the case of any Committed Loan, Letter of Credit or any
obligation to make Committed Loans or issue, extend or renew any Letter of
Credit or (y) the date of the related Money Market Quote, in the case of any
Money Market Loan, the adoption of any applicable law, rule or regulation, or
any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Bank (or
its

<PAGE>
                                      -46-

Applicable Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency shall
impose, modify or deem applicable any reserve (including, without limitation,
any such requirement imposed by the Board of Governors of the Federal Reserve
System, but excluding with respect to any Euro-Dollar Loan any such requirement
with respect to which such Bank is entitled to compensation during the relevant
Interest Period under Section 2.16), special deposit, insurance assessment or
similar requirement against assets of, deposits with or for the account of, or
credit extended by, any Bank (or its Applicable Lending Office) or shall impose
on any Bank (or its Applicable Lending Office) or on the United States market
for certificates of deposit or the London interbank market any other condition
affecting its Euro-Dollar Loans or Money Market Loans, its Note, its Letter of
Credit or its obligation to make Euro-Dollar Loans or Money Market Loans and the
result of any of the foregoing is to increase the cost to such Bank (or its
Applicable Lending Office) of making or maintaining any Euro-Dollar Loan or
Money Market Loan, or to reduce the amount of any sum received or receivable by
such Bank (or its Applicable Lending Office) under this Agreement or under any
Loan Document with respect thereto, by an amount deemed by such Bank to be
material, then, within 15 days after demand by such Bank (with a copy to the
Agent), the Borrower shall pay to such Bank such additional amount or amounts as
will compensate such Bank for such increased cost or reduction. The Borrower's
obligation under this Section 8.3(a) shall be limited to paying any costs which
the Bank incurs after or within 45 days prior to receipt by the Borrower of the
notice provided for under Section 8.3(c).

         (b)      If any Bank shall have determined that, after the date hereof,
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or 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 capital of such Bank (or its Parent) as
a consequence of such Bank's obligations hereunder to a level below that which
such Bank (or its Parent) could have achieved but for such adoption, change,
request or directive (taking into consideration its policies with respect to
capital adequacy) by an amount deemed by such Bank to be material, then from
time to time, within 15 days after demand by such Bank (with a copy to the
Agent), the Borrower shall pay to such Bank such additional amount or amounts as
will compensate such Bank (or its Parent) for such reduction. The Borrower's
obligation under this Section 8.3(b) shall be limited to paying any costs which
the Bank incurs after or within 90 days prior to receipt by the Borrower of the
notice provided for under Section 8.3(c) unless such costs were incurred prior
to such 90 day period as a result of such present or future applicable law being
retroactive to a date which occurred prior to such 90 day period and such Bank
or, as the case may be, the Agent, has given notice to the Borrower of the
effectiveness of such law within 90 days after the effective date thereof.

         (c)      Each Bank will promptly notify the Borrower and the Agent of
any event of which it has knowledge, occurring after the date hereof, which will
entitle such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and

<PAGE>
                                      -47-

will not, in the judgment of such Bank, be otherwise disadvantageous to such
Bank. A certificate of any Bank claiming compensation under this Section and
setting forth the calculation in reasonable detail of the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error, PROVIDED that the Borrower shall have the right, within 60 days
of receipt of such certificate, to demonstrate that the amount set forth in such
certificate is incorrect and request an adjustment of the amount to be, or
therefore, paid. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

         SECTION 8.4. BASE RATE LOANS SUBSTITUTED FOR AFFECTED EURO-DOLLAR LOANS
AND MONEY MARKET LOANS. If (i) the obligation of any Bank to make Euro-Dollar
Loans has been suspended pursuant to Section 8.2 or (ii) any Bank has demanded
compensation under Section 8.3(a) and the Borrower shall, by at least five
Euro-Dollar Business Days' prior notice to such Bank through the Agent, have
elected that the provisions of this Section shall apply to such Bank, then,
unless and until such Bank notifies the Borrower that the circumstances giving
rise to such suspension or demand for compensation no longer apply:

         (a)      all Loans which would otherwise be made by such Bank
Euro-Dollar Loans shall be made instead as Base Rate Loans (on which interest
and principal shall be payable contemporaneously with the related Euro-Dollar
Loans and Money Market Loans of the other Banks), and

         (b)      after each of its Euro-Dollar Loans has been repaid, all
payments of principal which would otherwise be applied to repay such Euro-Dollar
Loans and Money Market Loans shall be applied to repay its Base Rate Loans
instead.

         SECTION 8.5. SUBSTITUTION OF BANK. If (i) any Bank has required the
Borrower to pay additional amounts to or for the account of any Bank pursuant to
Section 2.15, (ii) the obligation of any Bank to make Euro-Dollar Loans has been
suspended pursuant to Section 8.2 or (iii) any Bank has demanded compensation
under Section 8.3, the Borrower shall, upon at least three Euro-Dollar Business
Days' notice to the Agent, have the right, with the assistance of the Agent, to
seek a mutually satisfactory substitute bank or banks (which may be one or more
of the Banks) to purchase the Note and the Letter of Credit Participations and
assume the Commitment of such Bank.

                                   ARTICLE IX.

                                  MISCELLANEOUS

         SECTION 9.1. NOTICES. All notices, requests and other communications to
any party hereunder shall be in writing (including bank wire, facsimile
transmission or similar writing) and shall be given to such party: (x) in the
case of the Borrower or the Agent, at its address set forth on the signature
pages hereof, (y) in the case of any Bank, at its address or facsimile number
set forth in its Administrative Questionnaire or (z) in the case of any party,
such other address as such party may hereafter specify for the purpose by notice
to the Agent and the Borrower. Each such notice, request or other communication
shall be effective (i) if given by mail, when delivered or (ii) if given by any
other means, when delivered at the address

<PAGE>
                                      -48-

specified in this Section; PROVIDED that notices to the Agent under Article II
or Article VIII shall not be effective until received.

         SECTION 9.2. NO WAIVERS. No failure or delay by the Agent or any Bank
in exercising any right, power or privilege hereunder or under any Note shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

         SECTION 9.3. EXPENSES: DOCUMENTARY TAXES; INDEMNIFICATION. (a) The
Borrower shall pay (i) all out-of-pocket expenses of the Agent and the
Arrangers, including fees and disbursements of special counsel for the Agent and
the Arrangers, in connection with the preparation of this Agreement, any waiver
or consent hereunder or any amendment hereof or any Default or alleged Default
hereunder and (ii) if an Event of Default occurs, all out-of-pocket expenses
incurred by the Agent and each Bank, including fees and disbursements of
counsel, in connection with such Event of Default and collection, bankruptcy,
insolvency and other enforcement proceedings resulting therefrom. The Borrower
shall indemnify each Bank against any transfer taxes (except in the case of any
voluntary transfer by a Bank to an Assignee or Participant hereunder),
documentary taxes, assessments or charges made by any governmental authority by
reason of the execution and delivery of this Agreement or the Notes.

         (b)      The Borrower agrees to indemnify each Bank, the Agent and the
Arrangers and hold each such Person harmless from and against any and all
liabilities, losses, damages, costs and expenses of any kind, including, without
limitation, the reasonable fees and disbursements of counsel, which may be
incurred by such Person in connection with any investigative, administrative or
judicial proceeding (whether or not such Person shall be designated a party
thereto) relating to or arising out of this Agreement or any actual or proposed
use of proceeds of Loans hereunder; PROVIDED that no Person shall have the right
to be indemnified hereunder for its own gross negligence or willful misconduct
as determined by a court of competent jurisdiction.

         SECTION 9.4. SETOFF. The Borrower hereby grants to the Agent and each
of the Banks a continuing lien, security interest and right of setoff as
security for all liabilities and obligations to the Agent and each Bank, whether
now existing or hereafter arising, upon and against all deposits, credits,
collateral and property, now or hereafter in the possession, custody,
safekeeping or control of the Agent or such Bank or any affiliate of any Bank
and their successors and assigns or in transit to any of them. Regardless of the
adequacy of any collateral, if any of the obligations owing from the Borrower to
the Agent or any Bank hereunder are due and payable and have not been paid or
any Event of Default shall have occurred, any deposits or other sums credited by
or due from any of the Banks to the Borrower and any securities or other
property of the Borrower in the possession of such Bank may be applied to or set
off by such Bank against the payment of such obligations and any and all other
liabilities, direct, or indirect, absolute or contingent, due or to become due,
now existing or hereafter arising, of the Borrower to such Bank. ANY AND ALL
RIGHTS TO REQUIRE ANY BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO
ANY OTHER COLLATERAL WHICH SECURES SUCH OBLIGATIONS, PRIOR TO EXERCISING ITS
RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE
BORROWER

                                      -49-

ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Banks
agree with each other Bank that (a) if an amount to be set off is to be applied
to Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced
by the Notes held by such Bank or constituting Reimbursement Obligations owed to
such Bank, such amount shall be applied ratably to such other Indebtedness and
to the Indebtedness evidenced by all such Notes held by such Bank or
constituting Reimbursement Obligations owed to such Bank, and (b) if such Bank
shall receive from the Borrower, whether by voluntary payment, exercise of the
right of setoff, counterclaim, cross action, enforcement of the claim evidenced
by the Notes held by, or constituting Reimbursement Obligations owed to, such
Bank by proceedings against the Borrower at law or in equity or by proof thereof
in bankruptcy, reorganization, liquidation, receivership or similar proceedings,
or otherwise, and shall retain and apply to the payment of the Note or Notes
held by, or Reimbursement Obligations owed to, such Bank any amount in excess of
its ratable portion of the payments received by all of the Banks with respect to
the Notes held by, and Reimbursement Obligations owed to, all of the Banks, such
Bank will make such disposition and arrangements with the other Banks with
respect to such excess, either by way of distribution, PRO TANTO assignment of
claims, subrogation or otherwise as shall result in each Bank receiving in
respect of the Notes held by it or Reimbursement Obligations owed it, its
proportionate payment as contemplated by this Agreement; PROVIDED that if all or
any part of such excess payment is thereafter recovered from such Bank, such
disposition and arrangements shall be rescinded and the amount restored to the
extent of such recovery, but without interest.

         SECTION 9.5. AMENDMENTS AND WAIVERS. Any provision of this Agreement or
the other Loan Documents may be amended or waived if, but only if, such
amendment or waiver is in writing and is signed by the Borrower and the Required
Banks (and, if the rights or duties of the Agent are affected thereby, by the
Agent); PROVIDED that no such amendment or waiver shall, unless signed by all
the Banks, (i) increase the Commitment of any Bank or subject any Bank to any
additional obligation, (ii) reduce the principal of or rate of interest on any
Loan or Reimbursement Obligation or any fees hereunder or reduce or forgive any
Reimbursement Obligation, (iii) postpone the date fixed for any payment of
principal of or interest on any Loan or any fees hereunder or for any reduction
or termination of any Commitment or postpone or extend the Termination Date or
(iv) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Notes, or the number of Banks, which shall be required
for the Banks or any of them to take any action under this Section or any other
provision of this Agreement or otherwise amend or waive this Section 9.5.

         SECTION 9.6. SUCCESSORS AND ASSIGNS. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

         (b)      Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans and in all or a portion of such Bank's rights and
obligations under this Agreement and the other Loan Documents. In the event of
any such grant by a Bank of a participating interest to a Participant,

<PAGE>
                                      -50-

whether or not upon notice to the Borrower and the Agent, such Bank shall remain
responsible for the performance of its obligations hereunder, and the Borrower
and the Agent shall continue to deal solely and directly with such Bank in
connection with such Bank's rights and obligations under this Agreement. Any
agreement pursuant to which any Bank may grant such a participating interest
shall provide that such Bank shall retain the sole right and responsibility to
enforce the obligations of the Borrower hereunder including, without limitation,
the right to approve any amendment, modification or waiver of any provision of
this Agreement; PROVIDED that such participation agreement may provide that such
Bank will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii) or (iii) of Section 9.5 which would directly
affect the Participant without the consent of the Participant. The Borrower
agrees that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Article VIII with respect to its
participating interest. An assignment or other transfer which is not permitted
by subsection (c) or (d) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this subsection (b).

         (c)      Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part of all, of its
rights and obligations under this Agreement (including all or a portion of its
Commitment Percentage and Commitment and the same portion of the Loans at the
time owing to it, the Notes held by it and its participating interest in the
risk relating to any Letters of Credit) (provided that any such assignment shall
be of an amount not less than $5,000,000), and such Assignee shall assume such
rights and obligations, pursuant to an Assignment and Assumption Agreement in
substantially the form of EXHIBIT G hereto executed by such Assignee and such
transferor Bank, with (and subject to) the subscribed consent of the Agent and,
unless a Default or Event of Default shall have occurred and be continuing, the
Borrower, which consent by the Agent and the Borrower shall not be unreasonably
withheld; PROVIDED that if an Assignee is another Bank or is an affiliate of
such transferor Bank, no such consent shall be required; and PROVIDED FURTHER
that such assignment may, but need not, include rights of the transferor Bank in
respect of outstanding Money Market Loans. Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required.

         Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Bank, the Agent and the Borrower shall make appropriate
arrangements so that, if required, a new Note is issued to the Assignee. In
connection with any such assignment, the transferor Bank shall pay to the Agent
an administrative fee for processing such assignment in the amount of $3,500. If
the Assignee is not incorporated under the laws of the United States of America
or a state thereof, it shall deliver to the Borrower and the Agent certification
as to exemption from deduction or withholding of any United States federal
income taxes in accordance with Section 2.15.

         (d)      (i) At any time, the Borrower may request that the Total
Commitment be increased, provided that, without the prior written consent of the
Required Banks, (1) the Total Commitment shall at no time exceed $300,000,000
minus the aggregate amount of all reductions in the Total Commitment under this
Agreement previously made pursuant to Section 2.9 or 2.10; (2) the Borrower
shall not be entitled to make any such request more frequently than twice in
each 12-month period; and (3) each such request shall be in a minimum amount of
at least $25,000,000 and increments of $5,000,000 in excess thereof. Such
request shall be made in a written notice given to the Agent and the Banks by
the Borrower not fewer than ten (10) Domestic Business Days prior to the
proposed effective date of such increase, which notice (a "Commitment Increase
Notice") shall specify the amount of the proposed increase in the Total
Commitment and the proposed effective date of such increase. In the event of
such a Commitment Increase Notice, each of the Banks shall be given the
opportunity to participate in the requested increase ratably in proportion that
its Commitment bears to the Total Commitment under this Agreement, respectively.
No Bank shall have any obligation to increase its Commitment pursuant to a
Commitment Increase Notice. On or prior to a date that is five (5) Domestic
Business Days after receipt of the Commitment Increase Notice, each Bank shall
submit to the Agent a notice indicating the maximum amount by which it is
willing to increase its Commitment in connection with such Commitment Increase
Notice (any such notice to the Agent being herein a "Lender Increase Notice").
Any Bank which does not submit a Lender Increase Notice to the Agent prior to
the expiration of such five (5) Business Day period shall be deemed to have
denied any increase in its Commitment. In the event that the increases of
Commitments set forth in the Lender Increase Notices exceed the amount requested
by the Borrower in the Commitment Increase Notice, the Agent and the Arrangers
shall have the right, in consultation with the Borrower, to allocate the amount
of increases necessary to meet the Borrower's Commitment Increase Notice;
provided, no Bank shall be allocated an amount less than its pro rata share of
such increase based upon the proportion its Commitment bears to the Total
Commitment under this Agreement. In the event that the Lender Increase Notices
are less than the amount requested by the Borrower, no later than three (3)
Domestic Business Days prior to the proposed effect date the Borrower may notify
the Agent of any financial institution that shall have agreed to become a "Bank"
party hereto (an "Acceding Bank") in connection with the Commitment Increase
Notice. Any Acceding Bank shall be consented to by the Agent (which consent
shall not be unreasonably withheld). If the Borrower shall not have arranged any
Acceding Bank(s) to commit to the shortfall from the Lender Increase Notices,
then the Borrower shall be deemed to have reduced the amount of its Commitment
Increase Notice to the aggregate amount set forth in the Lender Increase
Notices. Based upon the Lender Increase Notices, any allocations made in
connection therewith and any notice regarding any Acceding Bank, if applicable,
the Agent shall notify the Borrower and the Banks on or before the Domestic
Business Day immediately prior to the proposed effective date of the amount of
each Bank's and Acceding Bank's Commitment (the "Effective Commitment Amount")
and the amount of the Total Commitment, which amounts shall be effective on the
following Domestic Business Day subject to the conditions set forth herein. Any
increase in the Total Commitment under this Agreement shall be subject to the
following conditions precedent: (i) as of the date of the Commitment Increase
Notice and as of the proposed effective date of the increase in the Total
Commitment under this Agreement, all representations and warranties shall be
true and correct in all material respects as though made on such date (unless
such representation and warranty is made as of a specific date, in which case,
such representation and warranty shall be true and

<PAGE>
                                      -52-

correct as of such date) and no event shall have occurred and then be continuing
which constitutes a Default or Event of Default under this Agreement; (ii) the
Borrower, the Agent and each Acceding Bank shall have agreed to provide a
"Commitment" in support of such increase in the Total Commitment under this
Agreement, shall have executed and delivered an "Instrument of Accession"
substantially in the form of EXHIBIT H hereto; (iii) counsel for the Borrower
shall have provided to the Agent supplemental opinions in form and substance
reasonably satisfactory to the Agent and (iv) the Borrower and the Acceding
Bank(s) shall otherwise have executed and delivered such other instruments and
documents as may be required under Article III or that the Agent shall have
reasonably requested in connection with such increase. Upon satisfaction of the
conditions precedent to any increase in the Total Commitment under this
Agreement, the Agent shall promptly advise the Borrower and each Bank of the
effective date of such increase. Upon the effective date of any increase the
Total Commitment under this Agreement that is supported by an Acceding Bank,
such Acceding Bank shall be a party to this Agreement as a Bank and shall have
the rights and obligations of a Bank hereunder. In addition, on the effective
date, the Agent shall replace the existing Schedule 1 attached hereto with the
revised Schedule 1 reflecting such new Total Commitment and each Bank's
Commitment. Nothing contained herein shall constitute, or otherwise be deemed to
be, a commitment on the part of any Bank to increase its Commitment hereunder.

         (ii)     For purposes of this clause (ii), (A) the term "Buying
Lender(s)" shall mean (1) each Bank the Effective Commitment Amount of which is
greater than its Commitment prior to the effective date of any increase in the
Total Commitment under this Agreement and (2) each Acceding Bank that is
allocated an Effective Commitment Amount in connection with any Commitment
Increase Notice and (B) the term "Selling Lender(s)" shall mean each Bank whose
Commitment under this Agreement is not being increased from that in effect prior
to such increase in the Total Commitment under this Agreement as the case may
be. Effective on the effective date of any increase in the Total Commitment
under this Agreement pursuant to clause (i) above, each Selling Lender hereby
sells, grants, assigns and conveys to each Buying Lender, without recourse,
warranty or representation of any kind, except as specifically provided herein,
an undivided percentage in such Selling Lender's right, title and interest in
and to its outstanding Committed Loans in the respective amounts and percentages
necessary so that, from and after such sale, each such Selling Lender's
outstanding Committed Loans shall equal such Selling Lender's pro rata share
(calculated based upon the Effective Commitment Amounts) of the outstanding
Committed Loans under this Agreement as applicable. Effective on the effective
date of any increase in the Total Commitment under this Agreement pursuant to
clause (i) above, each Buying Lender hereby purchases and accepts such grant,
assignment and conveyance from the Selling Lenders. Each Buying Lender hereby
agrees that its respective purchase price for the portion of the outstanding
Committed Loans purchased hereby shall equal the respective amount necessary so
that, from and after such payments, each Buying Lender's outstanding Committed
Loans shall equal such Buying Lender's pro rata share (calculated based upon the
Effective Commitment Amounts) of the outstanding Committed Loans under this
Agreement. Such amount shall be payable on the effective date of the increase in
the Total Commitment under this Agreement by wire transfer of immediately
available funds to the Agent. The Agent, in turn, shall wire transfer any such
funds received to the Selling Lenders, in same day funds, for the sole account
of the Selling Lenders. Each Selling Lender hereby represents and warrants to
each Buying Lender that such Selling Lender owns the

<PAGE>
                                      -53-

Committed Loans being sold and assigned hereby for its own account and has not
sold, transferred or encumbered any or all of its interests in such Committed
Loans, except for participations which will be extinguished upon payment to the
Selling Lender of any amount equal to the portion of the outstanding Committed
Loans being sold by such Selling Lender. Each Buying Lender hereby acknowledges
and agrees that, except for such Selling Lender's representations and warranties
contained in the foregoing sentence, each such Buying Lender has entered into
its Instrument of Accession with respect to such increase on the basis of its
own independent investigation and has not relied upon, and will not rely upon,
any explicit or implicit written or oral representation, warranty or other
statement of the Banks or the Agent concerning the authorization, execution,
legality, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or the other Loan Documents. The Borrower hereby agrees to
compensate each Selling Lender for all losses, expenses and liabilities incurred
by each Bank in connection with the sale and assignment of any Euro-Dollar
Borrowing hereunder on the terms and in the manner set forth in Section 2.13
hereof.

         (e)      Any Bank may at any time assign all or any portion of its
rights under this Agreement and its Note to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

         (f)      No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under Section 2.15 or
8.3 than such Bank would have been entitled to receive with respect to the
rights transferred, unless such transfer is made with the Borrower's prior
written consent or by reason of the provisions of Section 2.15, 8.2 or 8.3
requiring such Bank to designate a different Applicable Lending Office under
certain circumstances or at a time when the circumstances giving rise to such
greater payment did not exist.

         SECTION 9.7. COLLATERAL. Each of the Banks represents to the Agent and
each of the other Banks 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 9.8. GOVERNING LAW: SUBMISSION TO JURISDICTION. This Agreement
and each Note shall be governed by and construed in accordance with the laws of
the State of New York. The Borrower hereby submits to the nonexclusive
jurisdiction of the United States District Court for the Southern District of
New York and of any New York State court sitting in New York City for purposes
of all legal proceedings arising out of or relating to this Agreement or the
transactions contemplated hereby. The Borrower irrevocably waives, to the
fullest extent permitted by law, any objection which it may now or hereafter
have to the laying of the venue of any such proceeding brought in such a court
and any claim that any such proceeding brought in such a court has been brought
in an inconvenient forum.

         SECTION 9.9. COUNTERPARTS: INTEGRATION. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement constitutes the entire agreement and understanding among the
parties hereto and supersedes any and all prior agreements and understandings,
oral or written, relating to the subject matter hereof.

                                      -54-

         SECTION 9.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENT AND
THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION 9.11. SEVERABILITY. The provisions of this Agreement are
severable and if any one clause or provision hereof shall be held invalid or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such clause or provision
in any other jurisdiction, or any other clause or provision of this Agreement in
any jurisdiction.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.
