offered by four major banks in the London interbank market at approximately
11:00 a.m. (London time), on the day that is two (2) London Banking Days

rate for that date will be the arithmetic mean of the quotations. If fewer than
two quotations are provided as requested, the rate for that date will be

European banks for a period of time comparable to such Interest Period offered
by major banks in New York City at approximately 11:00 a.m. (New York City time)

Rate for such day shall be such rate on such transactions on the next preceding
Business Day as so published on the next succeeding Business Day, and (b) if

such Business Day shall be the average rate charged to the Agent on such

         In addition, if the Borrower raises additional capital through an
equity sale, the Banks shall have the option to require the Borrower to apply up
to 50% of the net sale proceeds from such sale to the reduction of their
Commitments. The proceeds will be applied on the date of the sale to the
scheduled Commitment reductions in inverse order.

         (b) On the effective date of each reduction of the Commitments of the
Banks pursuant to Section 2.5(a), the Borrower shall repay such principal amount
(together with accrued interest thereon and any amount due pursuant to Section
2.7(b)) of outstanding Revolving Loans, if any, as may be necessary so that
after such repayment the aggregate unpaid principal amount of the Revolving
Loans owed to the Banks does not exceed the aggregate Commitments of the Banks
as then reduced.

         Section 2.6. CONVERSION OR CONTINUATION OF REVOLVING LOANS. The
Borrower shall have the right to Convert Revolving Loans of one type into
Revolving Loans of another type or to Continue Eurodollar Rate Loans, at any
time or from time to time, PROVIDED that: (a) the Borrower shall give the Agent
a Notice of Continuation or Conversion in the form of EXHIBIT B-2, as
applicable, prior to 11:00 a.m. (California time) on the date at least three (3)
Business Days prior to the last day of the Interest Period of any Revolving Loan
to be Converted into or Continued as a Eurodollar Rate Loan; (b) Eurodollar Rate
Loans may be Converted or Continued only on the last day of an Interest Period
for such Revolving Loans; (c) each Conversion or Continuation of a Eurodollar
Rate Loan shall be in an amount at least equal to $250,000 or in any greater
amount which is an integral multiple thereof; (d) no Event of Default shall have

                                      -20-
<PAGE>

occurred and be continuing at the time of any Conversion to a Eurodollar Rate
Loan or Continuation of any such Eurodollar Rate Loan into a subsequent Interest
Period; (e) accrued interest on the Revolving Loan (or portion thereof) being
Converted or Continued shall be paid by the Borrower at the time of Continuation
or Conversion; and (f) each request for a Continuation as or Conversion to a
Eurodollar Rate Loan which fails to state an applicable Interest Period shall be
deemed to be a request for an Interest Period of one (1) month.

         Notwithstanding anything to the contrary herein contained, if, upon the
expiration of any Interest Period applicable to any Eurodollar Rate Loan, the
Borrower shall fail to give a Notice of Continuation or Conversion as set forth
in this Section 2.6, the Borrower shall be deemed to have given a Notice of
Continuation of such Eurodollar Rate Loan in principal amount equal to the
outstanding principal amount of such Eurodollar Rate Loan and having an Interest
Period of one (1) month.

         Section 2.7. OPTIONAL PREPAYMENTS.

         (a) The Borrower may, upon at least one (1) Business Day's notice to
the Agent, prepay the Base Rate Loans, without premium or penalty, in whole at
any time or from time to time in part by paying the principal amount being
prepaid together with accrued interest thereon to the date of prepayment.

         (b) The Borrower may, upon at least three (3) Business Days' notice to
the Agent, prepay the Eurodollar Rate Loans, in whole at any time or from time
to time in part, by paying the principal amount being prepaid together with (i)
accrued interest thereon to the date of prepayment and (ii) if such prepayment
occurs on a date that is not the last day of the Interest Period applicable to
such Eurodollar Rate Loan, any amounts as shall be sufficient (in the reasonable
opinion of the Banks) to compensate each Bank for any reasonable losses, costs
or expenses (excluding any losses of anticipated profit), as certified by such
Bank (such certification setting forth the basis for such compensation), which
such Bank may reasonably incur as a result of such prepayment, including without
limitation, any loss, cost or expense incurred by reason of funds liquidation or
reemployment of deposits or other funds acquired by such Bank to fund or
maintain such Eurodollar Rate Loan and any administrative costs, expenses or
charges of such Bank as a result thereof.

         Without limiting the effect of the preceding sentence, compensation
shall include a "yield maintenance fee" in an amount computed as follows: The
current rate for United States Treasury securities (bills on a discounted basis
shall be converted to a bond equivalent) with a maturity date closest to the
last day of the Interest Period of the Revolving Loan as to which the prepayment
is made, shall be subtracted from the Eurodollar Rate for such Interest Period
in effect at the time of prepayment. If the result is zero or a negative number,
there shall be no yield maintenance fee. If the result is a positive number,
then the resulting percentage shall be multiplied by the amount of the principal
balance being prepaid. The resulting amount shall be divided by 360 and
multiplied by the number of days remaining in the Interest Period as to which
the prepayment is made. Said amount shall be reduced to present value calculated
by using the above referenced United States Treasury securities rate and the
number of days remaining in the

                                      -21-
<PAGE>

Interest Period as to which the prepayment is made. The resulting amount shall
be the yield maintenance fee due to the Agent upon payment of such Eurodollar
Rate Loan. If by reason of an Event of Default, the Required Banks elect to
declare the Revolving Notes to be immediately due and payable, then any yield
maintenance fee with respect to a Eurodollar Rate Loan shall become due and
payable in the same manner as though the Borrower had exercised such right of
prepayment.

         (c) Upon receipt of any notice of prepayment from the Borrower pursuant
to Section 2.7(a) or 2.7(b), the Agent shall promptly give notice thereof to
each Bank. If any such notice is given by the Borrower, the amount specified in
such notice shall be due and payable on the date specified therein.

         Section 2.8. INTEREST ON THE REVOLVING LOANS.

         (a) Each Base Rate Loan shall bear interest on the outstanding
principal amount thereof, for each day from the date such Base Rate Loan is made
until it becomes due, at a rate per annum equal to the Base Rate for such day,
plus the Applicable Margin. Interest shall be payable on the last day of the
Interest Period applicable thereto. Such interest shall accrue from and
including the date of such Borrowing to but excluding the date of any repayment
thereof and shall be computed on the basis of a fraction, the numerator of which
is the actual number of days elapsed from the date of Borrowing and the
denominator of which is three hundred sixty (360).

         (b) Each Eurodollar Rate Loan shall bear interest on the unpaid
principal amount thereof, for each day from the date such Eurodollar Rate Loan
is made until it becomes due, at a rate per annum equal to the Eurodollar Rate
for the relevant Interest Period, plus the Applicable Margin. Interest shall be
payable on the last day of the Interest Period applicable thereto; PROVIDED,
that if such Interest Period is longer than ninety (90) days, interest shall be
payable every ninety (90) days and on the last day of such Interest Period. Such
interest shall accrue from and including the date of such Borrowing to but
excluding the date of any repayment thereof and shall be computed on the basis
of a fraction, the numerator of which is the actual number of days elapsed from
the date of Borrowing and the denominator of which is three hundred sixty (360).

         (c) Overdue principal of, and to the extent permitted by law, interest
on each Revolving Loan shall bear interest for each day until paid at a rate per
annum equal to the Default Rate.

         Section 2.9. FEES. The Borrower shall pay to the Agent for the ratable
benefit of the Banks a nonrefundable stand-by commitment fee for the Commitment
Period, payable in arrears at the rate of one-half (1/2) of one percent (1%) per
annum, on the average daily unused portion of each Bank's Commitment with
respect to the Revolving Loans, which stand-by commitment fee shall be payable
quarterly on the first Business Day of January, April, July, and October of each
year beginning April 1, 2000. Such fee shall be computed on the basis of a year
of three hundred sixty (360) days and actual days elapsed.

         Section 2.10. PRO RATA TREATMENT AND PAYMENTS GENERALLY. Each payment
by the Borrower on account of the principal of and interest on the Revolving
Loans, and any reduction of the Commitments of the Banks, shall be payable to
the Banks on a pro rata basis. All payments under this Agreement shall be made
in Dollars in immediately available funds not later than 1:00 p.m.
(Massachusetts time) on the due date (each such payment made after such time on
such due date to be deemed to have been made on the next succeeding Business
Day) to the Agent at its address set forth on the signature pages hereof or at
such other address as it may hereafter designate by notice to the Borrower and
the Banks for the account of the Lending Office of each Bank specified by such
Bank on SCHEDULE 1.1 HERETO. The Agent shall distribute such payments to the
Banks promptly upon receipt in like funds as received. If such payment is not
made available by the Agent to any Bank within one (i) Business Day of the
Agent's receipt of payment from the Borrower, such Bank shall be entitled to
recover such amount from the Agent with interest thereon at a rate per annum
equal to the Base Rate. The Borrower shall, at the time of making each payment
under this Agreement, specify to the Agent the principal or other amount payable
by the Borrower under this Agreement to which such payment is to be applied (and
in the event that it fails to so specify, or if a Default or Event of Default
has occurred and is continuing, the Agent may apply such payment as it may elect
in its sole discretion). The Borrower authorizes the Agent to charge any account
maintained by the Borrower at the Agent to satisfy the Borrower's payment
obligations hereunder. If any account is so charged on the due date, the payment
shall be deemed to have been timely made. If the due date of any payment under
this Agreement would otherwise fall on a day which is not a Business Day, such
date shall be extended to the next succeeding Business Day and such extension of
time shall in such case be included in the computation of such payment; PROVIDED
that, if such extension would cause the last day of an Interest Period to occur
in the next following calendar month, the last day of such Interest Period shall
occur on the immediately preceding Business Day.

         Section 2.11. CAPITAL ADEQUACY. If after the date hereof, either (i)
the introduction of, or any change in, or in the interpretation or enforcement
of, any law, regulation, order, ruling, interpretation, directive, guideline or
request or (ii) the compliance with any order, ruling, interpretation,
directive, guideline or request from any central bank or other governmental
authority (whether or not having the force of law) issued, announced, published,
promulgated or made after the date hereof (including, in any event, any law,
regulation, order, ruling, interpretation, directive, guideline or request
contemplated by the report dated July, 1988 entitled "International Convergence
of Capital Measurement and Capital Standards" issued by the Basle Committee on
Banking Regulation and Supervisory Practices) affects or would affect the amount
of capital required or expected to be maintained by any Bank or any corporation
controlling such Bank and such Bank reasonably determines that the amount of
such required or expected capital is increased by or based upon the existence of
such Bank's Revolving Loans hereunder or such Bank's commitment to lend
hereunder, then, upon demand by such Bank, through the Agent, the Borrower shall
be liable for, and shall pay to such Bank, within thirty (30) days following
demand from time to time by the Bank, through the Agent, additional amounts
sufficient to compensate such Bank in the light of such circumstances for the
effects of such law, regulation,

                                      -23-
<PAGE>

order, ruling, interpretation, directive, guideline or request, to the extent
that such Bank reasonably determines such increase in capital to be allocable to
the existence of such Bank's Revolving Loans hereunder or of such Bank's
commitment to lend hereunder. A certificate substantiating such amounts and
identifying the event giving rise thereto, which shall be submitted to the
Borrower by such Bank, through the Agent, at the time of its demand for such
compensation, shall be conclusive, absent demonstrable error. Each Bank shall
promptly notify the Borrower, through the Agent, of any event of which it has
knowledge occurring after the date of this Agreement which will entitle such
Bank to compensation pursuant to this Section, and each Bank shall take any
reasonable action available to it consistent with its internal policy and legal
and regulatory restrictions (including the designation of a different Lending
Office, if any) that will avoid the need for, or reduce the amount of, such
compensation and will not in the reasonable judgment of such Bank be otherwise
disadvantageous to such Bank.

         Section 2.12. INCREASED COSTS. (a) If after the date hereof, due to
either (i) the introduction of or any change in or in the interpretation or
enforcement of, any law, regulation, order, ruling, directive, guideline or
request, or (ii) the compliance with any order, ruling, directive, guideline or
request from any central bank or other governmental authority (whether or not
having the force of law) issued, announced, published, promulgated or made after
the date hereof, there shall be any increase in the cost to any Bank of agreeing
to make or making, funding or maintaining Eurodollar Rate Loans, then the
Borrower shall be liable for, and shall from time to time, within thirty (30)
days following a demand by such Bank, through the Agent, pay to such Bank for
the account of such Bank additional amounts sufficient to compensate such Bank
for such increased cost; PROVIDED, HOWEVER, that before making any such demand,
each Bank agrees to use reasonable efforts (consistent with its internal policy
and legal and regulatory restrictions) to designate a different Lending Office
if the making of such a designation would allow such Bank or its Lending Office
to continue to perform its obligations to make Eurodollar Rate Loans or to
continue to fund or maintain Eurodollar Rate Loans and would not, in the
reasonable judgment of such Bank, be otherwise disadvantageous to such Bank. A
certificate substantiating the amount of such increased cost, which shall be
submitted to the Borrower by the Bank, through the Agent, at the time of its
demand for such compensation, shall be conclusive, absent demonstrable error.

         (b) Upon notice by the relevant Bank, through the Agent, accompanied by
a certificate showing in reasonable detail the calculation of such amount, the
Borrower shall reimburse each Bank and shall hold each Bank harmless from any
loss or expense which the Banks may sustain or incur as a consequence of the
failure of the Borrower to (i) make a Borrowing hereunder after the Borrower has
given a Notice of Borrowing or (ii) make any optional prepayment after the
Borrower has provided notice thereof under Section 2.7 hereof.

         Section 2.13. ILLEGALITY. (a) Notwithstanding any other provision of
this Agreement, if after the date hereof the introduction of, or any change in
or in the interpretation or enforcement of, any law, regulation, order, ruling,
directive, guideline or request shall make it unlawful, or any central bank or
other governmental authority shall assert that it is unlawful, for any Bank or
its Lending Office to perform its obligations hereunder to make Eurodollar Rate
Loans or to continue to fund or maintain Eurodollar Rate Loans hereunder, then,
on notice thereof by such

                                      -24-
<PAGE>

Bank, through the Agent, to the Borrower, (i) the obligation of such Bank to
make Eurodollar Rate Loans shall terminate (and such Bank shall make all of its
Revolving Loans as Base Rate Loans notwithstanding any election by the Borrower
to have such Bank make Eurodollar Rate Loans) and (ii) if legally permissible,
at the end of the current Interest Period for such Eurodollar Rate Loans, and
otherwise five (5) Business Days after such notice and demand, all Eurodollar
Rate Loans of such Bank then outstanding will automatically convert into Base
Rate Loans; PROVIDED, HOWEVER, that before making any such demand, each Bank
agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to designate a different Lending Office if the
making of such a designation would allow such Bank or its Lending Office to
continue to perform its obligations to make Eurodollar Rate Loans and would not,
in the judgment of such Bank, be otherwise disadvantageous to such Bank. A
certificate describing such introduction or change in or in the interpretation
or enforcement of such law, regulation, order, ruling, directive, guideline or
request, which shall be submitted to the Borrower by such Bank, through the
Agent, at the time of its demand, shall be conclusive evidence of such
introduction, change, interpretation or enforcement, absent demonstrable error.
Each of the Banks and the Borrower agree to negotiate in good faith in order to
agree upon a mutually acceptable mechanism to provide that Eurodollar Rate Loans
made by any Bank as to which the foregoing conditions occur shall convert into
Base Rate Loans.

         (b) Notwithstanding any other provision of this Agreement, if after the
date hereof the Agent determines that quotations of interest rates for the
relevant deposits referred to in the definition of "Eurodollar Rate" in Section
1.1 hereof are not being provided in the relevant amounts or for the relevant
maturities for purposes of determining rates of interest for Eurodollar Rate
Loans and as a result the Agent ceases to make Eurodollar Rate Loans or
comparable loans generally available to other customers, then, on notice thereof
by the Agent to the Borrower, (i) the obligation of the Banks to make Eurodollar
Rate Loans shall terminate (and the Banks shall make all Revolving Loans as Base
Rate Loans notwithstanding any election by the Borrower to have the Banks make
Eurodollar Rate Loans). A certificate describing such event submitted to the
Borrower by the Agent shall be conclusive evidence of such event, absent
manifest error.

         Section 2.14. PAYMENTS TO BE FREE OF DEDUCTIONS. All payments by the
Borrower under this Agreement shall be made without setoff or counterclaim and
free and clear of, and without deduction for, any taxes (other than any taxes
imposed on or measured by the gross income or profits of any Bank or applicable
Lending Office thereof), levies, imposts, duties, charges, fees, deductions,
withholdings, compulsory loans, restrictions or conditions of any nature now or
hereafter imposed or levied by any country or any political subdivision thereof
or taxing or other authority therein unless the Borrower is compelled by law to
make such deduction or withholding. If any such obligation is imposed upon the
Borrower with respect to any amount payable by it hereunder, it will pay to
Agent, on the date on which such amount becomes due and payable hereunder and in
Dollars, such additional amount as shall be necessary to enable each Bank to
receive the same net amount which it would have received on such due date had no
such obligation been imposed upon the Borrower. If, at any time, any Bank, or
any permitted assignee of such Bank hereunder (an "Assignee"), is organized
under the laws of any jurisdiction other than the United States or any state or
other political subdivision thereof, such Bank or the Assignee shall deliver to
the Borrower, through the Agent, on the date it becomes a party to this

                                      -25-
<PAGE>

Agreement, and at such other times as may be necessary in the determination of
the Borrower in its reasonable discretion, such certificates, documents or other
evidence, properly completed and duly executed by such Bank or the Assignee
(including, without limitation, Internal Revenue Service Form 1001 or Form 4224
or any other certificate or statement of exemption required by Treasury
Regulations Section 1.1441-4(a) or Section 1.1441-6(c) or any successor thereto)
to establish that such Bank or the Assignee is not subject to deduction or
withholding of United States Federal Income Tax under Section 1441 or 1442 of
the Internal Revenue Code or otherwise (or under any comparable provisions of
any successor statute) with respect to any payments to such Bank or the Assignee
of principal, interest, fees or other amounts payable hereunder. The Borrower
shall not be required to pay any additional amount to such Bank or any Assignee
under this Section 2.14 if such Bank or such Assignee shall have failed to
satisfy the requirements of the immediately preceding sentence; PROVIDED that if
any Bank or any Assignee shall have satisfied such requirements on the date it
became a party to this Agreement, nothing in this Section 2.14 shall relieve
Borrower of its obligation to pay any additional amounts pursuant to this
Section 2.14 in the event that, as a result of any change in applicable law,
such Bank or such Assignee is no longer properly entitled to deliver
certificates, documents or other evidence at a subsequent date establishing the
fact that such Bank or the Assignee is not subject to withholding as described
in the immediately preceding sentence.

         Section 2.15. COMPUTATIONS. All computations of interest and like
payments hereunder on the Revolving Loans shall, in the absence of clearly
demonstrable error, be considered correct and binding on the Borrower and the
Banks, unless within thirty (30) Business Days after receipt of any notice by
the Agent of such outstanding amount, the Borrower or any Bank notifies the
Agent in writing to the contrary.

         Section 2.16. SHARING OF PAYMENTS, ETC. If any Bank shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
setoff, or otherwise) on account of the Revolving Loans made by it (other than
pursuant to Sections 2.11,.2.12, 2.13 or 2.14) in excess of its ratable share of
payments on account of outstanding Revolving Loans obtained by all the Banks,
such Bank shall forthwith purchase from the other Banks such participations in
the Revolving Loans made by them as shall be necessary to cause such Bank to
share the excess payment ratably with each of them; PROVIDED, HOWEVER, that if
all or any portion of such excess payment is thereafter recovered from such
purchasing Bank, such purchase from each Bank shall be rescinded and each such
Bank shall repay to the purchasing Bank the purchase price to the extent of such
recovery, together with an amount equal to such Bank's ratable share (according
to the proportion of (i) the amount of such Bank's required repayment to (ii)
the total amount so recovered from the purchasing Bank) of any interest or other
amount paid or payable by the purchasing Bank in respect of the total amount so
recovered. The Borrower agrees that any Bank so purchasing a participation from
another Bank pursuant to this Section 2.17 may, to the fullest extent permitted
by law, exercise all its rights of payment (including the right of setoff) with
respect to such participation as fully as if such Bank were the direct creditor
of the Borrower in the amount of such participation.

         Section 2.17. NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Agent shall
have been notified in writing by a Bank prior to any date on which a Revolving
Loan is to be made, which

                                      -26-
<PAGE>

notice shall be effective upon receipt, that such Bank does not intend to make
available to the Agent such Bank's pro rata share of the Revolving Loan
requested, the Agent may assume that such Bank has made such amount available to
the Agent on such date and Agent may, in its sole discretion (but shall not be
obligated to), make available to the Borrower a corresponding amount on such
date. If such corresponding amount is not in fact made available to the Agent by
such Bank, the Agent shall be entitled to recover such corresponding amount on
demand from such Bank together with interest thereon, for each day from the date
the Agent made such amount available to the Borrower until the date such amount
is repaid to the Agent, at a rate per annum equal to the Federal Funds Rate for
two days and thereafter at the Default Rate. If Such Bank does not pay such
corresponding amount forthwith upon the Agent's demand therefor, the Agent shall
promptly notify the Borrower and the Borrower shall immediately pay such
corresponding amount to the Agent provided, however, that in such event the
Borrower shall not have any obligation under Section 2.7(b) or Section 2.12(b)
to reimburse such Bank for any loss, cost or expense which such Bank may incur
as a result of such prepayment and such payment by the Borrower shall not be
deemed a failure to make a borrowing hereunder after the Borrower shall have

operations of the Borrower and its Subsidiaries, taken as a whole, for the
periods covered by such statements, all in accordance with GAAP consistently
applied (subject to year-end accruals and audit adjustments and the absence of
footnotes in the case of the interim financial statements). There are no
liabilities of the Borrower or any Subsidiary, fixed or contingent, which are
material but are not reflected in the financial statements or in the notes
thereto, other than liabilities arising in the ordinary course of business since
June 30, 1999 and other than this Agreement and the other Loan Documents. No
written information, exhibit or report furnished by the Borrower to the Agent or
any Bank in connection with the negotiation of this Agreement contained any
material misstatement of fact or omitted to state any fact necessary to make the
statements contained therein not materially misleading. Since June 30, 1999 no

Borrower or its Subsidiaries and for which the Borrower or its Subsidiaries has
established and maintains adequate reserves for payment. To the best knowledge
of the Borrower, there is no tax assessment contemplated or proposed by any
governmental agency against the Borrower or any of its Subsidiaries that would
have a Materially Adverse Effect.

         Section 4.8. ERISA. Each of the Borrower and its Subsidiaries is in
compliance in all material respects with all applicable provisions of ERISA.
Within the three-year period prior to the date hereof, neither a Reportable
Event nor a Prohibited Transaction has occurred with respect to any Plan; no

bureau, agency or instrumentality, domestic or foreign, which would, in any one
case or in the aggregate, have a Materially Adverse Effect.

         Section 4.13. NO DEFAULTS ON OTHER AGREEMENTS. Neither the Borrower nor
any of its Subsidiaries is a party to any indenture, mortgage or loan or credit
agreement or any lease or other agreement or instrument or subject to any

         Section 4.17. ENVIRONMENTAL PROTECTION. Each of Borrower and its
Subsidiaries has obtained all permits, licenses and other authorizations which
are required under all environmental laws, including laws relating to emissions,
discharges, releases or threatened releases of pollutants, contaminants,
chemicals or industrial, toxic or hazardous substances or wastes into the
environment (including without limitation, ambient air, surface water, ground
water, or land), or otherwise relating to the manufacture, processing,
distribution, use, treatment, storage, disposal, transport, or handling of
pollutants, contaminants, chemicals, or industrial, toxic or hazardous
substances or wastes, except to the extent failure to have any such permit,
license or authorization would not reasonably be expected to have a Materially
Adverse Effect. Each of the Borrower and its Subsidiaries is in compliance with
all terms and conditions of the required permits, licenses and authorizations,
and is also in compliance with all other limitations, restrictions, conditions,
standards, prohibitions, requirements, obligations, schedules and timetables
contained in the environmental laws or contained in any regulation, code, plan,
order, decree, judgment, injunction, notice or demand letter issued, entered,
promulgated or approved thereunder, except to the extent failure to comply would
not reasonably be expected to have a Materially Adverse Effect. None of the
Properties of the Borrower or its Subsidiaries, either owned or leased, have
been included or, as far as the Borrower can reasonably foresee, proposed for
inclusion on the National Priorities List adopted pursuant to the Comprehensive
Environmental Response Compensation and Liability Act, as amended, or on any
similar list or inventory of sites requiring response or cleanup actions adopted
by any other federal, state or local agency.

         Section 4.18. COPYRIGHTS, PATENTS, TRADEMARKS, ETC. Each of the
Borrower and its Subsidiaries owns or is duly licensed or otherwise entitled to
use all patents, trademarks, service marks, trade names, and copyrighted
materials ("Intellectual Property") which are used in the operation of its
business as presently conducted, except where the failure to be so licensed or
entitled would not have a Materially Adverse Effect. SCHEDULE 4.18 sets forth a
listing of all Intellectual Property that is material to the operation of the
business of the Borrower and its Subsidiaries as presently and proposed to be
conducted. No claim is pending or, as far as the Borrower can reasonably
foresee, threatened against the Borrower or any of its Subsidiaries contesting
the use of any such Intellectual Property, nor does the Borrower know of any
valid basis for any such claims, other than claims which, if adversely
determined, would not have a Materially Adverse Effect. To the best of the
Borrower's knowledge, the use of such Intellectual Property by the Borrower and
each Subsidiary does not infringe on the rights of any Person, except for such
claims and infringements that, in the aggregate, could not have a Materially
Adverse Effect.

         Section 4.19. COMPLIANCE WITH LAWS. Neither the Borrower nor any of its
Subsidiaries is in violation of any laws, ordinances, rules or regulations,
applicable to it, of any federal, state or municipal governmental authorities,
instrumentalities or agencies, including without limitation, the United States
Occupational Safety and Health Act of 1970, as amended, except where such
violation would not have a Materially Adverse Effect. The Borrower and each

                                      -35-
<PAGE>

Subsidiary is in compliance with all laws and other requirements applicable to
its business and has obtained all authorizations, consents, approvals, orders,
licenses, and permits from, and the Borrower and each Subsidiary has
accomplished all filings, registrations, and qualifications with, or obtained
exemptions from any of the foregoing from, any governmental or public agency
that are necessary for the transaction of its business, except where the failure
to be in such compliance, obtain such authorizations, consents, approvals,
orders, licenses, and permits, accomplish such filings, registrations, and
qualifications, or obtain such exemptions, would not have a Materially Adverse
Effect.

         Section 4.20. EVENTS OF DEFAULT. No Default or Event of Default has
occurred and is continuing.

         Section 4.21. NO ADVERSE CHANGE. Since December 31, 1998, there has
occurred no event which has had or, as far as the Borrower can reasonably
foresee, could have a Materially Adverse Effect, except as is disclosed by the
Borrower's Quarterly Report on Form 10-Q for the quarterly period ended June 30,
1999.

         Section 4.22. USE OF PROCEEDS. The Borrower shall use the proceeds of
any Revolving Loans made on or after the Amendment Effective Date for general
corporate purposes of the Borrower. No part of such proceeds shall be used to
purchase or carry, or to extend credit to others for the purpose of purchasing
or carrying, any "margin stock" (as such term is defined in Regulation U of the
Board of Governors of the Federal Reserve System) in violation of Regulations U

corporate existence and good standing in the jurisdiction of its incorporation,
and qualify and remain qualified as a foreign corporation in each jurisdiction
in which such qualification is required from time to time, except where failure

         Section 5.3. MAINTENANCE OF PROPERTIES. Maintain, keep and preserve all
of its material Properties (tangible and intangible), necessary or useful in the

tear excepted, EXCEPT that the failure to maintain, preserve and protect a
particular item of depreciable Property that is not of significant value, either
intrinsically or to the operations of the Borrower and its Subsidiaries, taken
as a whole, shall not constitute a violation of this covenant.

         Section 5.4. MAINTENANCE OF RECORDS. Keep accurate and complete records
and books of account, in which complete entries will be made in accordance with
GAAP reflecting all financial transactions of the Borrower and its Subsidiaries,

insurance companies, in such amounts and with such coverages (including without
limitation public liability insurance, fire, hazard and extended coverage

all other coverages as are consistent with industry practice) as are maintained
by companies of established reputation engaged in similar businesses and
similarly situated and furnish to the Agent, upon written request, full
information as to the insurance carried.

         Section 5.6. COMPLIANCE WITH LAWS. Comply in all respects with all
applicable laws, rules, regulations and orders, except where the failure to so
comply would not have a Materially Adverse Effect. Such compliance shall
include, without limitation, paying all taxes, assessments and governmental

if any, related thereto), unless contested in good faith by appropriate
proceedings and for which adequate reserves have been set aside.

         above, such event or condition, together with all other such events or
         conditions, if any, would in the reasonable opinion of the Agent

         Multiemployer Plan, the PBGC or otherwise (or any combination thereof)
         which in the aggregate exceed or may exceed $100,000 or;

         after its execution and delivery and for any reason cease to be in full
         force and effect or shall be declared null and void, or the validity or
         enforceability thereof shall be contested by the Borrower or the

each Bank to be terminated, whereupon the same shall forthwith terminate, (ii)
declare all amounts owing under this Agreement and the Revolving Notes (whether

of which are hereby expressly waived by the Borrower; PROVIDED that, in the case
of an Event of Default referred to in Section 7.1(f) above with respect to the
Borrower, the Commitment of each Bank shall be immediately automatically
terminated, and all such amounts shall be immediately due and payable without
notice, presentment, demand, protest or other formalities of any kind, all of
which are hereby expressly waived by the Borrower.

Agreement and the other Loan Documents on the part of the Borrower, (iv) shall
not be responsible to any Bank for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement and the
other Loan Documents or any other instrument or document furnished pursuant
hereto or thereto; and (v) shall incur no liability under or in respect of this
Agreement and the other Loan Documents by acting upon any notice, consent,
certificate or other instrument or writing (which may be by telegram, cable,
telex or telecopy) purported to be genuine and signed or sent by the proper
party or parties. The Agent shall in all cases be fully protected in acting, or
in refraining from acting, under this 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 all the Banks.

         Section 8.3. NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from a Bank or the Borrower,
describing such Default or Event of Default and stating that such notice is a
"notice of default". In the event that the Agent receives such a notice, the
Agent shall give prompt notice thereof to the Banks. The Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Banks, PROVIDED that unless and until the Agent shall
have received such directions, the Agent

                                      -51-
<PAGE>

may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Banks; PROVIDED FURTHER, that Agent shall
not be required to take any action which exposes the Agent to liability or which
is contrary to this Agreement, the other Loan Documents or applicable law.

         Section 8.4. FLEET AND AFFILIATES. With respect to its Commitment and
the Revolving Loans made by it, the Agent shall have the same rights and powers
with respect to this Agreement or the Revolving Notes as any other Bank and may
exercise the same as though it were not the Agent; and the term "Bank" or
"Banks" shall, unless otherwise expressly indicated, include Fleet in its
individual capacity. Fleet and its Affiliates may accept deposits from, lend
money to, act as trustee under indentures of, and generally engage in any kind
of business with, the Borrower and its Affiliates and any of their respective
Affiliates and any Person who may do business with or own securities of the
Borrower or its Affiliates all as if Fleet were not the Agent, and without any
duty to account therefor to the Banks.

         Section 8.5. CREDIT DECISION. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other bank and based on
such information as it deems necessary (the receipt of which such Bank
acknowledges), 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 action under this Agreement and the
other Loan Documents.

         Section 8.6. INDEMNIFICATION. The Banks severally and ratably agree to
indemnify the Agent (to the extent not reimbursed by the Borrower), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against the
Agent in any way relating to or arising out of this Agreement and the other Loan
Documents, or any action taken or omitted by the Agent under this Agreement and
the other Loan Documents, provided that no Bank shall be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Bank agrees to reimburse the Agent promptly upon demand for its ratable
share of any out-of-pocket expenses (including reasonable counsel fees) incurred
by the Agent in connection with the preparation, execution, administration, or
enforcement of, or legal advice in respect of rights or responsibilities under,
this Agreement and the other Loan Documents, to the extent that the Agent is not
reimbursed for such expenses by the Borrower.

         Section 8.7. SUCCESSOR AGENT. The Agent may not resign as Agent under
this Agreement without the prior written consent of the Borrower. Upon any such
resignation, the Required Banks shall have the right to appoint a successor
Agent hereunder with the approval of the Borrower, which shall not be
unreasonably withheld. 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's resignation, then the retiring Agent may, on behalf of the
Banks,

                                      -52-
<PAGE>

appoint a successor Agent with the approval of the Borrower, which shall not be
unreasonably withheld, which shall be a commercial bank organized under the laws
of the United States of America or of any state thereof and having a combined
capital and surplus of at least $500,000,000. Upon the acceptance of any
appointment as Agent under this Agreement by a successor Agent, such successor
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement arising from and
after the date of resignation. After any retiring Agent's resignation as Agent
under this Agreement, the provisions of this Article 8 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement.

         Section 8.8. APPLICATION OF THIS ARTICLE TO THE BORROWER.
Notwithstanding anything to the contrary in this Article 8, the provisions of
Sections 8.1, 8.2, 8.3, 8.5 and 8.6 shall be deemed to govern the rights and
obligations as among the Banks and the Agent only, and shall not be construed to
affect any rights or obligations of the Borrower with respect to the Banks and
the Agent.

                            ARTICLE 9. MISCELLANEOUS.

         Section 9.1 AMENDMENTS AND WAIVERS. No amendment or waiver of any
provision of this Agreement or any other Loan Document nor consent to any
departure by the Borrower or any Subsidiary therefrom, shall in any event be
effective unless the same shall be in writing and signed by the Agent, the
Borrower or the applicable Subsidiary, and the Required Banks and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. Notwithstanding the foregoing, the written
consent of all of the Banks shall be required for any amendment or waiver having
the effect of (i) extending the Revolving Loan Termination Date (except as
expressly provided for herein), extending the time of payment of principal,
interest or fees on any Revolving Loans or reducing or forgiving the principal
amount thereof (other than by repayment), decreasing the interest rate borne by
any Revolving Loans, increasing the amount of any Bank's Commitment over the
amount then in effect (it being understood that a waiver of any Default or Event
of Default or a mandatory reduction in the Commitment shall not constitute an
increase in any Commitment of any Bank), or postponing or reducing any scheduled
reduction of the Commitment (except as set forth herein), (ii) reducing the
percentage specified in the definition of Required Banks, (iii) amending or
waiving any provision of this Section 9.1, (iv) releasing any guaranty or any
collateral under the Security Documents or (v) consenting to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement or any other Loan Agreement. No failure on the part of the Agent or
any Bank to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof or preclude any other or further exercise thereof or
the exercise of any other right. The remedies herein provided are cumulative and
not exclusive of any remedies provided by law.

         Section 9.2. USURY. Anything herein to the contrary notwithstanding,
the Obligations of the Borrower with respect to this Agreement and the Revolving
Notes shall be subject to the limitation that payments of interest shall not be
required to the extent that receipt thereof would

                                      -53-
<PAGE>

be contrary to provisions of law applicable to the Banks limiting rates of
interest which may be charged or collected by the Banks.

         Section 9.3. EXPENSES; INDEMNITIES.

         (a) Unless otherwise agreed in writing by all of the Banks, the
Borrower shall reimburse the Agent and the Banks on demand for all reasonable
out-of-pocket costs, expenses and charges (including without limitation,
reasonable fees and charges of counsel for the Agent and the Banks) incurred by
the Agent and the Banks in connection with any amendment or modification of this
Agreement and the other Loan Documents. The Borrower further agrees to pay on
demand all reasonable costs and expenses (including reasonable counsel fees and
expenses), if any, in connection with the enforcement, including without
limitation, the enforcement of judgments (whether through negotiations, legal
proceedings or otherwise) of this Agreement, the other Loan Documents or any
other document to be delivered under this Agreement and all audits, all
insurance costs, and all other reasonable costs and expenses which the Agent or
any Bank has or shall have paid by reason of the Borrower's failure or refusal
to do so as and when required hereunder. The Borrower agrees to indemnify and
hold harmless the Agent and the Banks from and against any and all liabilities
with respect to or resulting from any delay in paying or omission to pay such
costs, expenses, charges and fees, except to the extent caused by the Agent's or
such Bank's negligence or willful misconduct or breach of this Agreement. Until
paid, the amount of any cost, expense or charge shall constitute, together with
all accrued interest thereon, part of the Obligations, and shall accrue interest
from the date five days after demand at the Base Rate. Nothwithstanding anything
to the contrary which may be stated or implied herein or in the Existing Credit
Agreement, it is explicitly understood and agreed that the Borrower is not
responsible for reimbursing or paying any costs, expenses or charges of the
Agent or any Banks in connection with the negotiation and preparation of this
Agreement.

         (b) The Borrower agrees to indemnify the Agent and each Bank, and their
directors, officers, employees, agents and Affiliates from, and hold each of
them harmless against, any and all claims, damages, losses, liabilities, costs
and expenses (including without limitation, reasonable fees and disbursements of
counsel) arising as a consequence of (i) any failure by the Borrower to pay the
Agent or any Bank, as required under this Agreement, punctually on the due date
thereof, any amount payable by the Borrower to the Agent or any Bank or (ii) the
acceleration, in accordance with the terms of this Agreement, of the time of
payment of any of the Obligations of the Borrower, except to the extent caused
by the Agent's or such Bank's negligence or willful misconduct or breach of this
Agreement. Such losses, costs or expenses may include, without limitation, (i)
any costs incurred by the Bank in carrying funds to cover any overdue principal,
overdue interest, or any other overdue sums payable by the Borrower to such Bank
or (ii) any losses incurred or sustained by any Bank in liquidating or
reemploying funds acquired by such Bank from third parties.

         (c) The Borrower agrees to indemnify the Agent and the Banks, and their
directors, officers, employees, agents and Affiliates from, and hold each of
them harmless against, any and all claims, damages, liabilities, losses, costs
and expenses (including without limitation,

                                      -54-
<PAGE>

reasonable fees and disbursements of counsel) arising out of or by reason of any
investigation or litigation or other proceedings (including any threatened
investigation or litigation or other proceedings) relating to any transaction
contemplated by this Agreement or any other Loan Document, any actions or
omissions of the Borrower or any Subsidiary or any of their respective
directors, officers, employees or agents in connection with this Agreement or
any other Loan Document, or any actual or proposed use by the Borrower or any
Subsidiary of the proceeds of the Revolving Loans, including without limitation,
the reasonable fees and disbursements of counsel incurred in connection with any
such investigation or litigation or other proceedings (but excluding any such
losses, liabilities, claims, damages or expenses incurred by reason of the gross
negligence or willful misconduct of the Person to be indemnified).

         (d) The Borrower agrees to indemnify the Agent and the Banks, and their
directors, officers, employees, agents and Affiliates from, and hold each of
them harmless against, any and all losses, liabilities, claims, damages, costs
and expenses (including without limitation, reasonable fees and disbursements of
counsel, engineers or similar professionals) which may be incurred by or
asserted against the Agent or any Bank or any such party in connection with or
arising out of or relating to (i) the Banks' compliance with any environmental
law with respect to the Properties or operations of the Borrower or its
Subsidiaries, (ii) any natural resource damages, governmental fines or penalties
or other amounts mandated by any governmental authority, court order, demand or
decree in connection with the disposal by the Borrower or its Subsidiaries
either on-site or off-site (including leakage or seepage from any such site
including third party treatment facilities) of pollutants, contaminants or
hazardous wastes and (iii) any personal injury or property damage to third
parties resulting from such pollutants, contaminants or hazardous wastes.

         Section 9.4. TERM; SURVIVAL. This Agreement shall continue in full
force and effect as long as any Obligations are owing by the Borrower to the
Agent or any Bank. No termination of this Agreement shall in any way affect or
impair the rights and obligations of the parties hereto relating to any
transactions or events prior to such termination date, and all warranties and
representations of the Borrower shall survive such termination. All
representations and warranties made hereunder and in any document, certificate,
or statement delivered pursuant hereto or in connection herewith shall survive
the execution and delivery of this Agreement and the other Loan Documents. The
obligations of the Borrower under Sections 2.11, 2.12 and 9.3 shall survive the
repayment of the Revolving Loans and the termination of the Commitment of each
Bank.

         Section 9.5. ASSIGNMENT; PARTICIPATIONS.

         (a) Upon thirty (30) days prior notice to the Borrower and with the
written consent of the Agent and the Borrower (which consent shall not be
unreasonably withheld), each Bank may assign to one or more commercial banks or
financial institutions all or a portion of its rights and obligations under this
Agreement (including without limitation, all or a portion of its Commitment and
the amounts under the Revolving Loans owing to it); provided, however, that (i)
each such assignment shall be of a constant, and not a varying, percentage of
all of the assigning Bank's rights and obligations under this Agreement, (ii)
the amount of the

                                      -55-
<PAGE>

Commitment of the assigning Bank being assigned pursuant to each such assignment
(determined as of the date of the Assignment and Acceptance) with respect to
such assignment shall in no event be less than $5,000,000 and shall be an
integral multiple of $500,000 (or in the case of an Assignment and Acceptance
covering all or the remaining portion of an assigning Bank's rights and
obligations under this Agreement, any lesser increment), and (iii) the parties
to each such assignment shall execute and deliver to the Agent, for its
acceptance and recording in the Register (as defined in (c) below), an
Assignment and Acceptance and a $3,500 non-refundable processing fee from the
assigning Bank. Notwithstanding the foregoing, no written consent of the
Borrower shall be required in connection with any assignment by a Bank to an
Affiliate of such Bank of all or a portion of its rights and obligations under
this Agreement. Upon such execution, delivery, acceptance and recording, from
and after the effective date specified in each Assignment and Acceptance, (x)
the assignee thereunder shall be a Bank party hereto and, to the extent that
rights and obligations (including any portion of any Commitment) hereunder have
been assigned to it pursuant to such Assignment and Acceptance, shall have the
rights and obligations of a Bank hereunder and (y) the Bank assignor thereunder
shall, to the extent that rights and obligations (including any portion of any
Commitment) hereunder have been assigned by it pursuant to such Assignment and
Acceptance, relinquish its rights (other than its rights to indemnification
under Section 9.3) and be released from its obligations under this Agreement
arising after the date of assignment (and, in the case of an assignment covering
all or the remaining portion of an assigning Bank's rights and obligations under
this Agreement, such Bank shall cease to be a party hereto.)

         (b) By executing and delivering an Assignment and Acceptance, the Bank
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows: (i) other than as provided in
such Assignment and Acceptance, such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto; (ii) such assigning Bank makes no representation or warranty and assumes
no responsibility with respect to the financial condition of the Borrower or the
performance or observance by the Borrower of any of its obligations under this
Agreement or any other instrument or document furnished pursuant hereto; (iii)
such assignee confirms that it has received a copy of this Agreement, together
with copies of the most recent financial statements referred to in Section 5.8
and such other documents and information as it has deemed appropriate to make
its own credit analysis and decision to enter into such Assignment and
Acceptance; (iv) such assignee will, independently and without reliance upon the
Agent, such assigning Bank 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 action under this Agreement; (v) such
assignee 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 and thereof,
together with such powers as are reasonably incidental thereto; (vi) such
assignee agrees that it will perform in accordance with the terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Bank; and (vii) such assignee represents that such assignment will not
result in any Prohibited Transaction.

                                      -56-
<PAGE>

         (c) The Agent shall maintain at its address set forth on the signature
pages hereto a copy of each Assignment and Acceptance delivered to and accepted
by it and a register for the recordation of the names and addresses of the Banks
and the Commitment of, and principal amount of the Revolving Loans owing to,
each Bank from time to time (the "Register"). The entries in the Register shall
be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Agent and the Banks may treat each Person whose name is recorded
in the Register as a Bank hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Borrower or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

         (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and its assignee, the Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of EXHIBIT E, (i)
accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register and (iii) give prompt notice thereof to the Borrower.

         (e) Each Bank may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under this
Agreement (including without limitation, all or a portion of its Commitment and
the amounts under the Revolving Loans owing to it); provided, however, that (i)
such Bank's obligations under this Agreement (including without limitation, its
Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Bank
shall remain solely responsible to the other parties hereto for the performance
of such obligations and (iii) the Borrower, the Agent and the other Banks shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under this Agreement; PROVIDED, that no Bank shall
transfer or grant any participation under which the participant shall have the
right to approve any amendment to or waiver of this Agreement or any Revolving
Note, except with respect to an extension of the final maturity of the Revolving
Loans or a reduction of the principal amount of or the rate of interest payable
on the Revolving Loans or any fees related thereto.

         (f) Any Bank may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 9.5, disclose to
the assignee or participant or proposed assignee or participant any information
relating to the Borrower furnished to such Bank by or on behalf of the Borrower;
provided that, prior to any such disclosure, the assignee or participant or
proposed assignee or participant shall agree in writing to preserve the
confidentiality of any confidential information relating to the Borrower
received by it from such Bank.

         (g) Nothing herein shall prohibit any Bank from pledging or assigning
all or any portion of such Bank's rights under this Agreement and the other Loan
Documents to a Federal Reserve Bank; PROVIDED, HOWEVER, that no such pledge or
assignment or enforcement thereof shall release such Bank from its obligations
hereunder or under any other Loan Document.

         Section 9.6. NOTICES. All notices, requests, demands and other
communications provided for herein shall be in writing and shall be (i) hand
delivered; (ii) sent by certified,

                                      -57-
<PAGE>

registered or express United States mail, return receipt requested, or reputable
next-day courier service; or (iii) given by telex, telecopy, telegraph or
similar means of electronic communication. All such communications shall be
effective upon the receipt thereof. Notices shall be addressed to the Borrower,
the Agent and the Banks at their respective addresses set forth on, in the case
of the Borrower and the Agent, the signature pages of this Agreement or, in the
case of the Banks, Schedule 1.1 to this Agreement, or to such other address as
the Borrower, the Agent or the Banks shall theretofore have transmitted to the
other party in writing by any of the means specified in this Section.

         Section 9.7. SETOFF. The Borrower agrees that, in addition to (and
without limitation of) any right of setoff, banker's lien or counterclaim the
Agent and each of the Banks may otherwise have, the Agent and each of the Banks
shall be entitled, at their option, to offset balances (general or special, time
or demand, provisional or final, and regardless of whether such balances are
then due to the Borrower) held by the Agent or any of the Banks for the account
of the Borrower at any of their offices, in Dollars or any other currency,
against any amount payable by the Borrower under this Agreement or any other
Loan Document which is not paid when due, taking into account any applicable
grace period, in which case the offsetting party shall promptly notify the
Borrower thereof; PROVIDED that failure to give such notice shall not affect the
validity thereof.

         Section 9.8. JURISDICTION; IMMUNITIES.

         (a) The Borrower hereby irrevocably submits to the jurisdiction of any
Massachusetts State or United States Federal court sitting in Massachusetts over
any action or proceeding arising out of or relating to this Agreement or any
other Loan Document, and the Borrower hereby irrevocably agrees that all claims
in respect of such action or proceeding may be heard and determined in such
Massachusetts State or Federal court. The Borrower irrevocably consents to the
service of any and all process in any such action or proceeding by the mailing
of copies of such process to the Borrower at its address specified in Section
9.6. The Borrower agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. The Borrower further waives any
objection to venue in such State and any objection to an action or proceeding in
such State on the basis of forum non conveniens. The Borrower further agrees
that any action or proceeding brought against the Bank shall be brought only in
Massachusetts State or United States Federal courts sitting in Massachusetts.

         (b) Nothing in this Section shall affect the right of the Agent and
each Bank to serve legal process in any other manner permitted by law or affect
the right of the Agent and each Bank to bring any action or proceeding against
the Borrower or its Property in the courts of any other jurisdictions.

         Section 9.9. TABLE OF CONTENTS; HEADINGS. Any table of contents and the

         Section 9.10. SEVERABILITY. The provisions of this Agreement are
intended to be severable. If for any reason any provision of this Agreement
shall be held invalid or unenforceable in whole or in part in any jurisdiction,
such provision shall, as to such jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without in any manner affecting the validity
or enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.

Massachusetts.

         Section 9.14. CONFIDENTIALITY. Subject to the following sentence, the

Agreement agrees to use its best efforts, consistent with its normal operating
procedures, to retain in confidence in accordance with each Bank's customary

any written information about the Borrower and its Subsidiaries obtained
pursuant to the requirements of this Agreement and identified in writing by the
Borrower as "confidential" or "non-public," except as permitted under Section

over the Agent or such Bank, (B) may disclose or otherwise use such information
to the extent that such information is required in response to any summons or

benefit of the Agent and the Banks. The Borrower agrees to confirm such

                                      -59-

such Bank's Revolving Note or any other security document which is not of public

upon cancellation of such Revolving Note or other security document, the
Borrower will issue, in lieu thereof, a replacement Revolving Note or other
security document in the same principal amount thereof and otherwise of like
