("Term Loan A") will continue under this Agreement. On March 29, 2000, the
Lender made Term Loan A to the Borrower in the principal amount of $3,500,000.
The obligations in connection with Term Loan A are evidenced by and payable in
accordance with the terms of a promissory note ("Term Note A") made in favor of
the Lender, dated as of March 29, 2000. Term Loan A shall be repaid in full,
together with any accrued and unpaid interest thereon, on the Termination Date.
Notwithstanding anything in Term Note A or this Agreement to the contrary, the
obligations in connection with Term Loan A shall become immediately due and
payable as provided in Section 10. No portion of Term Loan A that has been
repaid may be reborrowed.

         2.2 Revolving Loan Commitment. Subject to Section 9, from time to time
after the Closing Date until the Revolving Termination Date, the Lender will
make loans on a revolving basis (collectively, the "Revolving Loans") in such
aggregate amounts as the Borrower may, from time to time, request up to the
Revolving Commitment. The Indebtedness of the Borrower outstanding under the
Existing Note will be restructured as Revolving Loans under this Agreement, and
the term "Revolving Loans" will for all purposes include all such indebtedness
so restructured and any additional Revolving Loans made by the Lender under this
Section 2.2. The obligations in connection with the Revolving Loans will be
evidenced by and payable in accordance with the terms of a promissory note (the
"Revolving Note") made in favor of the Lender, dated as of the Closing Date and
in the form of Exhibit A. The Borrower has the right to repay and reborrow any
of the Revolving Loans; provided that it is a condition precedent to any
reborrowing that as of the date of any reborrowing all of the conditions to
borrowing set forth in Section 9.2 have been satisfied or waived. Each advance
to the Borrower will, on the day of such advance, be deposited, in immediately
available funds, in the Borrower's demand deposit account with the Lender or in
such other account as the Borrower may, from time to time, designate. All
Revolving Loans shall be repaid in full, together with any accrued and unpaid
interest thereon, on the Revolving Termination Date. Notwithstanding anything in
the Revolving Note or this Agreement to the contrary, the obligations in
connection with the Revolving Loans shall become immediately due and payable as
provided in Section 10.

         2.3 Borrowing Procedures. The Borrower shall give written notice or
telephonic notice (followed immediately by written confirmation thereof) to the
Lender of each proposed Revolving Loan not later than (i) in the case of a Base
Rate Loan, 11:00 A.M., Chicago time, on the proposed date of such Revolving Loan
and (ii) in the case of a Eurodollar Loan, 11:00 A.M., Chicago time, at least
three Business Days prior to the proposed date of such Revolving Loan. Each such
notice shall be effective upon receipt by the Lender, shall be irrevocable and

Eurodollar Loan, the initial Interest Period therefor. Each borrowing of a
Revolving Loan shall be on a Business Day.

described in Section 3.1(i)(a), each Loan shall be either a Base Rate Loan or a
Eurodollar Loan (each a "type" of Loan), as the Borrower shall specify on the
Closing Date or in a related notice of conversion pursuant to Section 2.5.
Eurodollar Loans having the same Interest Period are sometimes called a "group"
or collectively "groups". Base Rate Loans and Eurodollar Loans may be
outstanding at the same time; provided that (i) not more than seven different
groups of Eurodollar Loans shall be outstanding at any one time and (ii) the
aggregate principal amount of each group of Eurodollar Loans shall at all times
be at least $1,000,000 and an integral multiple of $500,000.

the Borrower may, upon irrevocable written notice to the Agent in accordance
with Section 2.5(b):

         (i)      elect, as of any Business Day, to convert any Loans (or, in
                  the case of Loans being converted into Eurodollar Loans, any
                  part thereof in an aggregate amount not less than $1,000,000
                  or a higher integral multiple of $500,000) into Loans of the
                  other type; or

         (ii)     elect, as of the last day of the applicable Interest Period,
                  to continue any Eurodollar Loans having Interest Periods
                  expiring on such day (or any part thereof in an aggregate
                  amount not less than $1,000,000 or a higher integral multiple
                  of $500,000) for a new Interest Period.

         (b) The Borrower shall give written or telephonic (followed immediately
by written confirmation thereof) notice to the Lender of each proposed
conversion or continuation not later than (i) in the case of conversion into
Base Rate Loans, 11:00 A.M., Chicago time, on the proposed date of such
conversion and (ii) in the case of conversion into or continuation of Eurodollar
Loans, 11:00 A.M., Chicago time, at least three Business Days prior to the
proposed date of such conversion or continuation, specifying in each case:

                  continuation; and

         (iv)     in the case of conversion into, or continuation of, Eurodollar
                  Loans, the duration of the requested Interest Period therefor.

         (c) If upon the expiration of any Interest Period applicable to
Eurodollar Loans, the Borrower has failed to select timely a new Interest Period
to be applicable to such Eurodollar Loans, the Borrower shall be deemed to have
elected to convert such Eurodollar Loans into Base Rate Loans effective on the
last day of such Interest Period.

         (d) Any conversion of a Eurodollar Loan on a day other than the last
day of an Interest Period therefor shall be subject to Section 6.4.

         (i)      with respect to Term Loan A, (a) so long as the Borrower
                  remains eligible to receive funds from STEP and so long as
                  funds in an amount at least equal to the then outstanding
                  principal amount of the Term Loan remain on deposit with the
                  Lender at the interest rates contemplated by STEP on the
                  Closing Date for purposes of funding the Borrower under STEP,
                  at the STEP Rate or (b) during any period of Term Loan A that
                  the Borrower is ineligible, as determined by the State of
                  Illinois' State Treasurer's Economic Program, to receive funds
                  from STEP or the State of Illinois ceases to maintain funds on
                  deposit with the Lender in the amounts and at the rates
                  contemplated by clause (i) (a) above for purposes of funding
                  the Borrower under STEP, at the rate set forth for Revolving
                  Loans in clause (ii) below;

extent calculated at the STEP Rate) and each Base Rate Loan shall be payable in
arrears on the last Business Day of each calendar quarter and at the Revolving
Termination Date or the Termination Date, as the case may be. Accrued interest

Date, as the case may be, accrued interest on all Loans shall be payable on
demand.

         3.3 Setting and Notice of Eurodollar Rates. The applicable Eurodollar
Rate for each Interest Period shall be determined by the Lender. Each

statement showing the computations used by the Lender in determining any
applicable Eurodollar Rate hereunder.

following Business Day.

         5.2 Application of Certain Payments. Each payment of principal shall be
applied to the Loans as the Borrower shall direct by notice to be received by
the Lender on or before the date of such payment or, in the absence of such
notice, as the Lender shall determine in its discretion. After an Event of
Default has occurred and is continuing, the Lender may apply any payments as the
Lender shall determine in its sole discretion.

         5.3 Due Date Extension. If any payment on the Liabilities falls due on
a day that is not a Business Day, then such due date shall be extended to the
immediately following Business Day (unless, in the case of a Eurodollar Loan,
such immediately following Business Day is the first Business Day of a calendar
month, in which case such date shall be the immediately preceding Business Day)
and, in the case of principal, additional interest shall accrue and be payable
for the period of any such extension.

         5.4 Setoff. The Borrower agrees that the Lender has all rights of
set-off and bankers' lien provided by applicable law, and in addition thereto,

not then due, any and all balances, credits, deposits, accounts or moneys of the
Borrower then or thereafter with the Lender.

         5.5 Taxes. All payments of principal of and interest on the Loans and

deduction for any present or future income, excise, stamp or franchise taxes and
other taxes, fees, duties, withholdings or other charges


                                       13
<PAGE>   19

of any nature whatsoever imposed by any taxing authority, but excluding
franchise taxes and taxes imposed on or measured by the Lender's net income or
receipts (all nonexcluded items being called "Taxes"). If any withholding or
deduction from any payment to be made by the Borrower hereunder is required in
respect of any Taxes pursuant to any applicable law, rule or regulation, then
the Borrower will:

         (i)      pay directly to the relevant authority the full amount
                  required to be so withheld or deducted;

         (ii)     promptly forward to the Lender an official receipt or other
                  documentation satisfactory to the Lender evidencing such
                  payment to such authority; and

         (iii)    pay to the Lender such additional amount or amounts as is
                  necessary to ensure that the net amount actually received by
                  the Lender will equal the full amount the Lender would have
                  received had no such withholding or deduction been required.
Moreover, if any Taxes are directly asserted against the Lender with respect to
any payment received by the Lender hereunder, the Lender may pay such Taxes and
the Borrower will promptly pay such additional amounts (including any penalty,
interest and expense) as is necessary so that the net amount received by the
Lender after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount the Lender would have received had such Taxes not
been asserted. If the Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to the Lender the required
receipts or other required documentary evidence, the Borrower shall indemnify
the Lender for any incremental Taxes, interest or penalties that may become
payable by the Lender as a result of any such failure.

                           SECTION 6: INCREASED COSTS;
                     SPECIAL PROVISIONS FOR EURODOLLAR LOANS

         6.1 Increased Costs. (a) If, after the Closing Date, 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 the Lender (or any Eurodollar Office of
the Lender) with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency:

         (i)      shall subject the Lender (or any Eurodollar Office of the
                  Lender) to any tax, duty or other charge with respect to the
                  Eurodollar Loans, the Notes or the Lender's obligation to make
                  Eurodollar Loans, or shall change the basis of taxation of
                  payments to the Lender of the principal of or interest on the
                  Eurodollar Loans or any other amounts due under this Agreement
                  in respect of the Eurodollar Loans or the Lender's obligation
                  to make Eurodollar Loans (except for changes in the rate of
                  tax on the overall net income of the Lender or its Eurodollar
                  Office imposed by the jurisdiction in which the Lender's
                  principal executive office or Eurodollar Office is located);

         (ii)     shall impose, modify or deem applicable any reserve (including
                  any reserve imposed by the Board of Governors of the Federal
                  Reserve System, but excluding any reserve


                                       14
<PAGE>   20

                  included in the determination of interest rates pursuant to
                  Section 3), special deposit or similar requirement against
                  assets of, deposits with or for the account of, or credit
                  extended by the Lender (or any Eurodollar Office of the
                  Lender); or

         (iii)    shall impose on the Lender (or its Eurodollar Office) any
                  other condition affecting the Eurodollar Loans, the Notes or
                  the Lender's obligation to make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to or to impose a
cost on the Lender (or any Eurodollar Office of the Lender) of making or
maintaining any Eurodollar Loan, or to reduce the amount of any sum received or
receivable by the Lender (or its Eurodollar Office) under this Agreement or
under any Note, then upon demand by the Lender, the Borrower shall pay directly
to the Lender such additional amount as will compensate the Lender for such
increased cost or such reduction.

         (b) If the Lender shall determine that the adoption or phase-in 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 compliance by the Lender or any
Person controlling the Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on the Lender's or such controlling Person's capital as a consequence of
the Lender's obligations hereunder to a level below that which the Lender or
such controlling Person could have achieved but for such adoption, change or
compliance (taking into consideration the Lender's or such controlling Person's
policies with respect to capital adequacy) by an amount deemed by the Lender or
such controlling Person to be material, then from time to time, upon demand by
the Lender, the Borrower shall pay to the Lender such additional amount or
amounts as will compensate the Lender or such controlling Person for such
reduction.

         6.2 Basis for Determining Interest Rate Inadequate or Unfair.  If with
respect to any Interest Period:

         (i)      deposits in Dollars (in the applicable amounts) are not being
                  offered to the Lender in the interbank eurodollar market for
                  such Interest Period, or the Lender otherwise determines
                  (which determination, if made in good faith, shall be binding
                  and conclusive on the Borrower) that by reason of
                  circumstances affecting the interbank eurodollar market
                  adequate and reasonable means do not exist for ascertaining
                  the applicable Eurodollar Rate; or

         (ii)     the Eurodollar Rate (Reserve Adjusted) as determined by the
                  Lender will not adequately and fairly reflect the cost to the
                  Lender of maintaining or funding such Eurodollar Loans for
                  such Interest Period or that the making or funding of
                  Eurodollar Loans has become impracticable as a result of an
                  event occurring after the date of this Agreement;

then the Lender shall promptly notify the other parties thereof and, so long as
such circumstances shall continue, (a) the Lender shall be under no obligation
to make Eurodollar Loans and (b) on the


                                       15
<PAGE>   21

last day of the current Interest Period for each Eurodollar Loan, such Loan
shall, unless then repaid in full, automatically convert to a Base Rate Loan.

         6.3 Changes in Law Rendering Eurodollar Loans Unlawful. If any change
in (including the adoption of any new) applicable law or regulation, or any
change in the interpretation of applicable law or regulation by any governmental
or other regulatory body charged with the administration thereof, should make it
(or in the good faith judgment of the Lender cause a substantial question as to
whether it is) unlawful for the Lender to make, maintain or fund Eurodollar
Loans, then the Lender shall promptly notify the Borrower and, so long as such
circumstances shall continue, (i) the Lender shall have no obligation to make or
convert into Eurodollar Loans and (ii) on the last day of the current Interest
Period for each Eurodollar Loan of the Lender (or, in any event, on such earlier
date as may be required by the relevant law, regulation or interpretation), such
Eurodollar Loan shall, unless then repaid in full, automatically convert to a
Base Rate Loan.

         6.4 Funding Losses. The Borrower hereby agrees that upon demand by the
Lender, the Borrower will indemnify the Lender against any net loss or expense
that the Lender may sustain or incur (including any net loss or expense incurred
by reason of the liquidation or reemployment of deposits or other funds acquired
by the Lender to fund or maintain any Eurodollar Loan) as a result of any
payment or prepayment of any Eurodollar Loan (including any conversion of any
such Eurodollar Loan into a Base Rate Loan) on a date other than the last day of
an Interest Period for such Loan. For this purpose, all notices to the Lender
pursuant to this Agreement shall be deemed to be irrevocable.

         6.5 Right of Lender to Fund through Other Offices. The Lender may, if
it so elects, fulfill its commitment as to any Eurodollar Loan by causing a
foreign branch or affiliate of the Lender to make such Loan; provided that in
such event for the purposes of this Agreement such Loan shall be deemed to have
been made by the Lender and the obligation of the Borrower to repay such Loan
shall nevertheless be to the Lender and shall be deemed held by it, to the
extent of such Loan, for the account of such branch or affiliate.

         6.6 Discretion of Lender as to Manner of Funding. Notwithstanding any
provision of this Agreement to the contrary, the Lender shall be entitled to
fund and maintain its funding of the Loans in any manner it sees fit, it being
understood, however, that for the purposes of this Agreement all determinations
hereunder shall be made as if the Lender had actually funded and maintained each
Eurodollar Loan during each Interest Period for such Loan through the purchase
of deposits having a maturity corresponding to such Interest Period and bearing
an interest rate equal to the Eurodollar Rate for such Interest Period.

         6.7 Conclusiveness of Statements; Survival of Provisions.
Determinations and statements of the Lender pursuant to Section 6.1, 6.2, 6.3 or
6.4 shall be conclusive absent manifest error. The Lender may use reasonable
averaging and attribution methods in determining compensation under Sections 6.1
and 6.4, and the provisions of such Sections shall survive repayment of the
Loans, cancellation of the Notes and any termination of this Agreement.

                    SECTION 7: REPRESENTATIONS AND WARRANTIES

         To induce the Lender to enter into this Agreement and to induce the
Lender to make the Loans, the Borrower represents and warrants to the Lender as
follows:

         7.1 Organization. The Borrower is a corporation duly incorporated,
validly existing and in good standing under the laws of its jurisdiction of
incorporation. The Borrower is in good standing and is duly qualified to do
business in the States of California, Colorado, Illinois, Indiana and Texas, the
Commonwealth of Massachusetts and each other jurisdiction where, because of the
nature of its activities or properties, such qualification is required, except
for such jurisdictions where the failure so to qualify would not have a Material
Adverse Effect.

         7.2 Authorization; No Conflict. The Borrower is duly authorized to
execute and deliver each Loan Document to which it is a party, the Borrower is
duly authorized to borrow monies under this Agreement and the Borrower is and
will continue to be duly authorized to perform its obligations under each Loan
Document to which it is a party. The execution, delivery and performance by the
Borrower of this Agreement and of each Loan Document to which it is a party, and
the borrowings by the Borrower under this Agreement, do not and will not (i)
require any consent or approval of any governmental agency or authority that has
not been obtained or (ii) conflict with (a) any provision of law, (b) the
articles of incorporation or by-laws of the Borrower, (c) any material agreement
binding upon the Borrower or its properties or assets or (d) any court or
administrative order or decree applicable to the Borrower, and do not and will
not require, or result in, the creation or imposition of any Lien on any asset
of the Borrower or any of its Subsidiaries.

         7.3 Validity and Binding Nature. Each of this Agreement and each other
Loan Document to which the Borrower is a party is the legal, valid and binding
obligation of the Borrower, enforceable against the Borrower in accordance with
its terms.

         7.4 Financial Condition. The audited financial statements of the
Borrower as of and for the fiscal years ended September 30, 1998, and September
30, 1999, and unaudited financial statements of the Borrower for the portion of
fiscal year 2000 up to and including December 31, 1999, copies of which have
been furnished prior to the Closing Date to the Lender, fairly present in all
material respects the assets, liabilities, revenues, expenses and cash flows of
the Borrower as of the dates thereof and the results of operations for the
periods covered thereby. The Borrower has no liability or unusual or long-term
commitment that might have a Material Adverse Effect and that is not reflected
in the financial statements referred to above.

         7.5 No Material Adverse Change. Since September 30, 1999, there has
been no event that has had or could be reasonably likely to have a Material
Adverse Effect.

         7.6 Litigation and Contingent Liabilities. Except as set forth in
Schedule 7.6, no litigation (including derivative actions), arbitration
proceeding or governmental investigation or proceeding is pending or, to the
Borrower's knowledge, threatened against the Borrower or any Subsidiary which
might reasonably be expected to have a Material Adverse Effect. There are no
injunctions or temporary restraining orders (either pending or, to the
Borrower's knowledge, threatened) that would prohibit the making of Loans. Other
than any liability incident to such


                                       17
<PAGE>   23

litigation or proceedings, neither the Borrower nor any Subsidiary has any
contingent liabilities not listed on Schedule 7.6 or permitted by Section 8.7.

         7.7 Taxes. The Borrower has filed, has caused to be filed or has been
included in all tax returns (federal, state, local, foreign and other material
tax returns) required to be filed by or on behalf of the Borrower and has paid
or caused to be paid all taxes and other governmental charges due for the
periods covered thereby, including interest and penalties, other than any such
taxes or charges (i) for which a timely and proper extension has been obtained
and (ii) that are being contested in good faith and by proper proceedings and as
to which appropriate reserves (in the reasonable judgment of the Lender) are
being maintained, unless and until any Lien resulting therefrom attaches to its
property and becomes enforceable against its other creditors. The reserves for
taxes reflected on the balance sheets of the Borrower submitted to the Lender in
accordance with the terms of Section 8.1 will be adequate in amount in
accordance with GAAP for the payment of all liabilities for all taxes (whether
or not disputed) of the Borrower accrued through the date of such balance sheet.

         7.8 Information. All information heretofore or contemporaneously with
this Agreement furnished in writing by the Borrower to the Lender for purposes
of or in connection with this Agreement and the transactions contemplated by
this Agreement is, and all written information hereafter furnished by or on
behalf of the Borrower or any Subsidiary to the Lender pursuant to this
Agreement or any other Loan Document or in connection with this Agreement will
be, true and accurate in every material respect on the date as of which such
information is dated or certified, and none of such information is or will be
incomplete by omitting to state any material fact necessary to make such
information not misleading in light of the circumstances under which made (it
being recognized by the Lender that any projections and forecasts provided by
the Borrower are based on good faith estimates and assumptions believed by the
Borrower to be reasonable as of the date of the applicable projections or
assumptions and that actual results during the period or periods covered by any
such projections and forecasts may differ from projected or forecasted results).

         7.9 Solvency. On the Closing Date, and immediately prior to and after
giving effect to the issuance of the Loans and the use of the proceeds thereof,
(i) the Borrower's assets will exceed its liabilities and (ii) the Borrower will
be solvent, will be able to pay its debts as they mature, will own property with
fair saleable value greater than the amount required to pay its debts and will
have capital sufficient to carry on its business as then constituted.

         7.10 No Default. No Event of Default or Unmatured Event of Default
exists or would result from the incurring by the Borrower of any Indebtedness
under this Agreement or under any other Loan Document. No contract or other
agreement to which the Borrower or any Subsidiary is a party has been terminated
or breached by the Borrower or any Subsidiary if such termination or breach
could have a Material Adverse Effect.

         7.11 Use of Proceeds. The Borrower will apply the proceeds of the Loans
under this Agreement to (i) partially finance the construction of a
manufacturing and distribution center in Aurora, Illinois and (ii) make the
Cabot Dividend.

         7.12     Subsidiaries.  The Borrower has no Subsidiaries.


                                       18
<PAGE>   24

         7.13 Ownership of Properties; Liens. Except as permitted pursuant to
Section 8.8, each of the Borrower and each Subsidiary owns good title to all of
its personal properties and assets, tangible and intangible, of any nature
whatsoever (including patents, trademarks, trade names, service marks and
copyrights), free and clear of all Liens, charges and claims (including
infringement claims with respect to patents, trademarks, service marks,
copyrights and the like).

         7.14 Intellectual Property. Except as set forth in Schedule 7.14, the
Borrower and each of its Subsidiaries owns and possesses or has a license or
other right to use all such patents, patent rights, trademarks, trademark
rights, trade names, trade name rights, service marks, service mark rights and
copyrights as are necessary for the conduct of the business of the Borrower and
its Subsidiaries as conducted on the Closing Date, without any infringement upon
rights of others which could reasonably be expected to have a Material Adverse
Effect.

         7.15 Insurance. Set forth on Schedule 7.15 is a complete and accurate
summary of the property and casualty insurance program of the Borrower and its
Subsidiaries as of the Closing Date (including the names of all insurers, policy
numbers, expiration dates, amounts and types of coverage, annual premiums,
exclusions, deductibles, self-insured retention and a description in reasonable
detail of any self-insurance program, retrospective rating plan, fronting
arrangement or other risk assumption arrangement involving the Borrower or any
Subsidiary).

         7.16 Investment Company Act; Public Utility Holding Company Act.
Neither the Borrower nor any Subsidiary is an "investment company" or a company
"controlled" by an "investment company", within the meaning of the Investment
Company Act of 1940. Neither the Borrower nor any Subsidiary is a "holding
company", or a "subsidiary company" of a "holding company", or an "affiliate" of
a "holding company" or of a "subsidiary company" of a "holding company", within
the meaning of the Public Utility Holding Company Act of 1935.

         7.17 Regulation U. The Borrower is not engaged principally, or as one
of its important activities, in the business of extending credit for the purpose
of purchasing or carrying Margin Stock.

         7.18 Securities Matters. The making of the Loans, the application of
the proceeds and repayment thereof by the Borrower and the consummation of the
transactions contemplated by this Agreement and the other Loan Documents will
not violate any provision of any federal or state securities statutes, rules or
regulations, or any order issued by the Securities and Exchange Commission
(collectively, the "Securities Laws"). The Borrower agrees to indemnify the
Lender and hold the Lender harmless from the claims of any Persons in connection
with any of the Securities Laws and relating to the making of the Loans or the
transactions contemplated by this Agreement and the other Loan Documents.

         7.19 Pension and Welfare Plans. (a) Except as set forth in Schedule
7.19, during the twelve-consecutive-month period prior to the date of the
execution and delivery of this Agreement, (i) no steps have been taken to
terminate any Pension Plan and (ii) no contribution failure has occurred with
respect to any Pension Plan sufficient to give rise to a Lien under Section
302(f) of ERISA. No condition exists or event or transaction has occurred with
respect to any Pension Plan which could result in the incurrence by the Borrower
of any material liability, fine or penalty. The Borrower has no contingent
liability with respect to any post-retirement benefit under a Welfare


                                       19
<PAGE>   25

Plan, other than liability for continuation coverage described in Part 6 of
Subtitle B of Title I of ERISA.

         (b) Except as set forth in Schedule 7.19, all contributions (if any)
have been made to any Multiemployer Pension Plan that are required to be made by
the Borrower or any other member of the Controlled Group under the terms of the
plan or of any collective bargaining agreement or by applicable law; neither the
Borrower nor any member of the Controlled Group has withdrawn or partially
withdrawn from any Multiemployer Pension Plan, incurred any withdrawal liability
with respect to any such plan, received notice of any claim or demand for
withdrawal liability or partial withdrawal liability from any such plan, and no
condition has occurred which, if continued, might result in a withdrawal or
partial withdrawal from any such plan; and neither the Borrower nor any member
of the Controlled Group has received any notice that any Multiemployer Pension
Plan is in reorganization, that increased contributions may be required to avoid
a reduction in plan benefits or the imposition of any excise tax, that any such
plan is or has been funded at a rate less than that required under Section 412
of the Code, that any such plan is or may be terminated, or that any such plan
is or may become insolvent.

         7.2 Environmental Matters.

         (a) To the best of the Borrower's knowledge, neither the Borrower nor
any Subsidiary, nor any operator of the Borrower's or any Subsidiary's
properties, is in violation, or alleged violation, of any judgment, decree,
order, law, permit, license, rule or regulation pertaining to environmental
matters, including those arising under RCRA, CERCLA, the Superfund Amendments
and Reauthorization Act of 1986 or any other Environmental Law which might
reasonably be expected to have a Material Adverse Effect.

         (b) Except for matters arising which would, individually, be expected
to have a Material Adverse Effect, neither the Borrower nor any Subsidiary has
received notice from any third party, including any federal, state or local
governmental authority (i) that any one of them has been identified by the
United States Environmental Protection Agency as a potentially responsible party
under CERCLA with respect to a site listed on the National Priorities List, 40
C.F.R. Part 300 Appendix B, (ii) that any hazardous waste, as defined by 42
U.S.C. ss.6903(5), any hazardous substance as defined by 42 U.S.C. ss.9601(14),
any pollutant or contaminant as defined by 42 U.S.C. ss.9601(33) or any toxic
substance, oil or hazardous material or other chemical or substance regulated by
any Environmental Law (all of the foregoing, "Hazardous Substances"), which any
one of them has generated, transported or disposed of has been found at any site
at which a federal, state or local agency or other third party has conducted a
remedial investigation, removal or other response action pursuant to any
Environmental Law, (iii) that the Borrower or any Subsidiary must conduct a
remedial investigation, removal, response action or other activity pursuant to
any Environmental Law or (iv) of any Environmental Claim.

         (c) Except as set forth on Schedule 7.20, (i) no portion of any real
property or other assets of the Borrower or any Subsidiary has been used for the
handling, processing, storage or disposal of Hazardous Substances except in
accordance in all material respects with applicable Environmental Laws, (ii) in
the course of any activities conducted by the Borrower, any Subsidiary or the
operators of any real property of the Borrower or any Subsidiary, no Hazardous
Substances have been generated or are being used on such properties except in
accordance in all material


                                       20
<PAGE>   26

respects with applicable Environmental Laws, (iii) there have been no Releases
or threatened Releases of Hazardous Substances on, upon, into or from any real
property or other assets of the Borrower or any Subsidiary, which might
reasonably be expected to have a Material Adverse Effect, (iv) there have been
no Releases on, upon, from or into any real property in the vicinity of any real
property or other assets of the Borrower or any Subsidiary which, through soil
or groundwater contamination, may have come to be located on, and which might

Substances generated by the Borrower and its Subsidiaries have been transported
offsite only by properly licensed carriers and delivered only to treatment or
disposal facilities maintaining valid permits as required under applicable
Environmental Laws, which transporters and facilities have been and are
operating in compliance in all material respects with such permits and
applicable Environmental Laws.

         7.21 Labor Matters. Neither the Borrower nor any Subsidiary is subject
to any labor or collective bargaining agreement. There are no existing or
threatened strikes, lockouts or other labor disputes involving the Borrower or
any Subsidiary that singly or in the aggregate could reasonably be expected to
have a Material Adverse Effect. Hours worked by and payment made to employees of
the Borrower and its Subsidiaries are not in violation of the Fair Labor
Standards Act or any other applicable law, rule or regulation dealing with such
matters.

         7.22 Year 2000 Issues. The computer systems in the Borrower's business
are capable of the following before, during or after January 1, 2000 ("Year 2000

                               of any thereof is subject that might reasonably

                         Multiemployer Pension Plan, or the taking of any action
                         with respect to a Pension Plan which could result in
                         the requirement that the Borrower furnish

                         any Pension Plan or Multiemployer Pension Plan which
                         could result in the incurrence by any member of the
                         Controlled Group of any material liability, fine or
                         penalty (including any claim or demand for withdrawal

                         any post-retirement Welfare Plan benefit, or any notice
                         that any Multiemployer Pension Plan is in
                         reorganization, that increased contributions may be
                         required to avoid a reduction in plan benefits or the
                         imposition of an excise tax, that any such plan is or
                         has been funded at a rate less than that required under
                         Section 412 of the Code, that any such plan is or may
                         be terminated, or that any such plan is or may become
                         insolvent;

                  (iv)   any cancellation or material change in any insurance
                         maintained by the Borrower or any Subsidiary; or

                  (v)    any event (including (a) any violation of any

                         Claim or (b) the enactment or effectiveness of any law,
                         rule or regulation) which might reasonably be expected
                         to have a Material Adverse Effect;

                  detailed financial and management reports submitted to the
                  Borrower by independent auditors in connection with each
                  annual or interim audit made by such auditors of the books of
                  the Borrower;

         (g)      promptly from time to time, copies of any notices (including,
                  without limitation, notices of default or acceleration)
                  received from any holder or trustee of, under or with respect
                  to any Indebtedness; and
         (h)      from time to time such other information concerning the
                  Borrower, its Subsidiaries and its Affiliates, as the Lender
                  may reasonably request.

         8.2 Maintenance of Existence. Maintain and preserve, and cause each
Subsidiary to maintain and preserve, (i) its existence and good standing in the
jurisdiction of its organization and (ii) its qualification and good standing as
a foreign corporation in each jurisdiction where the nature of its business
makes such qualification necessary (except in those instances in which the
failure to be qualified or in good standing could not have a Material Adverse
Effect).

         8.3 Compliance with Laws; Payment of Taxes and Liabilities. (i) Comply,
and cause each Subsidiary to comply, in all material respects with all
applicable laws (including Environmental Laws), rules, regulations, decrees,
orders, judgments, licenses and permits, except where failure to comply could
not reasonably be expected to have a Material Adverse Effect and (ii) pay, and
cause each Subsidiary to pay, prior to delinquency, all taxes and other
governmental charges against it or any of its property, as well as claims of any
kind which, if unpaid, might become a Lien on any of its property; provided that
the foregoing shall not require the Borrower or any Subsidiary to pay any such
tax or charge so long as it shall contest the validity thereof in good faith by
appropriate

maintain, with responsible insurance companies, such insurance as may be
required by any law or governmental regulation or court decree or order
applicable to it and such other insurance, to such extent and against such
hazards and liabilities (including business interruption insurance), as is
customarily maintained by companies similarly situated, but which shall insure
against all risks and liabilities of the type identified on Schedule 7.15 and
shall have insured amounts no less than, and deductibles no higher than, those
set forth on such schedule; and, upon request of the Lender, furnish to the
Lender a certificate setting forth in reasonable detail the nature and extent of
all insurance maintained by the Borrower and its Subsidiaries.

         8.5 Books, Records and Inspections. Keep, and cause each Subsidiary to
keep, its books and records in accordance with sound business practices
sufficient to allow the preparation of financial statements in accordance with
GAAP. The Borrower shall permit, and cause each Subsidiary to permit, at any
reasonable time and with reasonable notice (or at any time without notice if an
Event of Default exists), the Lender or any representative thereof to visit any
or all of its offices, to discuss its financial matters with its officers and
its independent auditors (and the Borrower authorizes such independent auditors
to discuss such financial matters with the Lender or any representative
thereof), and to examine (and, at the expense of the Borrower or the applicable
Subsidiary, photocopy extracts from) any of its books or other records.

                  income or similar taxes paid or accrued by the Borrower and
                  its Subsidiaries minus (3) non-cash gains received by the

                  quarters, ($10,000,000); it being understood that, by way of
                  example, ($2,000,000) is greater than ($1,000,000).

                 SECTION 9: EFFECTIVENESS; CONDITIONS OF LENDING

         The obligation of the Lender to make any Loan and amend and restate the

                  (i)    affirming the matters set forth in Section 9.2 as of
                         the Closing Date;

                  (ii)   stating that there has been no change in the certified
                         copies of the Borrower's articles of incorporation and

                         Existing Credit Agreement; and

                  (iii)  stating that the officers authorized to sign the
                         Existing Credit Agreement are the same officers
                         authorized to sign the Loan Documents and that the
                         Lender may rely on the sample of the true signature of
                         each such officer provided in connection with the
                         Existing Credit Agreement (it being understood that the
                         Lender may conclusively rely on each such certificate
                         until formally advised by a like certificate of any
                         changes therein);

         (c)      certified copies of all documents evidencing any necessary
                  corporate or partnership action, consents and governmental
                  approvals (if any) required for the execution, delivery and

         9.2 Subsequent Loans.  The obligation of the Lender to make each Loan
is subject to the following further conditions precedent that:

         (a) Compliance with Representations and Warranties, No Default. Both
before and after giving effect to the making of the Loans the following
statements shall be true and correct:

                  (i)    the representations and warranties of the Borrower set
                         forth in this Agreement and the other Loan Documents
                         shall be true and correct in all material respects with
                         the same effect as if then made (except to the extent
                         stated to relate to a


                                       29
<PAGE>   35

                         specific earlier date, in which case such
                         representations and warranties shall be true and
                         correct as of such earlier date); and

                  (ii)   no Event of Default or Unmatured Event of Default shall
                         have then occurred and be continuing.

         (b) Compliance with STEP. The Borrower will provide the Lender with
evidence satisfactory to the Lender that the Borrower qualifies for STEP and the
State of Illinois has deposited an amount equal to the original principal amount
of Term Loan A with the Lender at an interest rate equal to the STEP rate in
effect on the Closing Date.

         (c) Confirmatory Certificate. If requested by the Lender, the Lender
shall have received a certificate dated the date of such requested Loan and
signed by a Responsible Officer as to the matters set out in Sections 9.2(a) and
9.2(b) (it being understood that each request by the Borrower for the making of
a Loan shall be deemed to constitute a warranty by the Borrower that the
conditions precedent set forth in Sections 9.2(a) and 9.2(b) will be satisfied
at the time of the making of such Loan), together with such other documents as
the Lender may reasonably request in support thereof.

                 SECTION 10: EVENTS OF DEFAULT AND THEIR EFFECT

         10. Events of Default. Each of the following shall constitute an Event
of Default under this Agreement:

         (a)      default in the payment of any principal or interest on the
                  Loans when such principal and interest is due or declared due
                  (whether by scheduled maturity, acceleration, demand or
                  otherwise) or other Liabilities remain unpaid for five
                  Business Days after notice to the Borrower;

         (b)      any default shall occur under the terms applicable to any
                  indebtedness of the Borrower or any Subsidiary in an aggregate
                  amount (for all such indebtedness so affected) exceeding
                  $5,000,000 and such default shall (i) consist of the failure
                  to pay such indebtedness when due, whether by acceleration or
                  otherwise or (ii) accelerate the maturity of such indebtedness
                  or permit the holder or holders thereof, or any trustee or
                  agent for such holder or holders, to cause such indebtedness
                  to become due and payable prior to its expressed maturity;

         (c)      the Borrower or any Subsidiary becomes insolvent or generally
                  fails to pay, or admits in writing its inability or refusal to
                  pay, debts as they become due; or the Borrower or any
                  Subsidiary applies for, consents to, or acquiesces in the
                  appointment of a trustee, receiver or other custodian for the
                  Borrower or such Subsidiary or any property thereof, or makes
                  a general assignment for the benefit of creditors; or, in the
                  absence of such application, consent or acquiescence, a
                  trustee, receiver or other custodian is appointed for the
                  Borrower or any Subsidiary or for a substantial part of the
                  property of any thereof and is not discharged within 30 days;
                  or the bankruptcy, reorganization, debt arrangement, or other
                  case or proceeding under the bankruptcy or insolvency law, or
                  any dissolution or liquidation proceeding, is commenced in



                                       30
<PAGE>   36

                  respect of the Borrower or any Subsidiary, and if such case or
                  proceeding is not commenced by the Borrower or such
                  Subsidiary, it is consented to or acquiesced in by the
                  Borrower or such Subsidiary, or remains for 30 days
                  undismissed; or the Borrower or any Subsidiary takes any
                  action to authorize, or in furtherance of, any of the
                  foregoing;

         (d)      failure by the Borrower to comply with or to perform any
                  covenant (i) under Sections 8.2, 8.3, 8.4 and 8.17 and such
                  failure remains unremedied for ten days after the earlier of
                  (A) the Borrower's knowledge of such failure or (B) written
                  notice of such failure by the Lender to the Borrower or (ii)
                  under any other Section of this Agreement or any other Loan
                  Document;

         (e)      any representation and warranty made by the Borrower herein or
                  any other Loan Document is breached or is false or misleading
                  in any material respect, or any schedule, certificate,
                  financial statement, report, notice or other writing furnished
                  by the Borrower to the Lender in connection herewith is false
                  or misleading in any material respect on the date as of which
                  the facts therein set forth are stated or certified;

         (f)      final judgments which exceed an aggregate of $5,000,000 shall
                  be rendered against the Borrower or any Subsidiary and shall
                  not have been paid, discharged or vacated or had execution
                  thereof stayed pending appeal within 30 days after entry or
                  filing of such judgments;

         (g)      (i) institution of any steps by the Borrower or any other
                  Person to terminate a Pension Plan if as a result of such
                  termination the Borrower could be required to make a
                  contribution to such Pension Plan, or could incur a liability
                  or obligation to such Pension Plan, in excess of $5,000,000,
                  (ii) a contribution failure occurs with respect to any Pension
                  Plan sufficient to give rise to a Lien under Section 302(f) of
                  ERISA or (iii) there shall occur any withdrawal or partial
                  withdrawal from a Multiemployer Pension Plan and the
                  withdrawal liability (without unaccrued interest) to
                  Multiemployer Pension Plans as a result of such withdrawal
                  (including any outstanding withdrawal liability that the
                  Borrower and the Controlled Group have incurred on the date of
                  such withdrawal) exceeds $5,000,000; or

         (h)      a Change in Control shall occur.

         10.2 Effect of Event of Default. If any Event of Default described in
Section 10.1(c) shall occur, the Loans (if they have not theretofore terminated)
shall immediately terminate and all obligations hereunder shall become
immediately due and payable and the Lender shall have no further obligation to
make Revolving Loans, all without presentment, demand, protest or notice of any
kind; and, if any other Event of Default shall occur and be continuing, the
Lender may declare the Loans (if they have not theretofore terminated) to be
terminated or declare all obligations hereunder to be due and payable, whereupon
the Loans (if they have not theretofore terminated) shall immediately terminate
and all obligations hereunder shall become immediately due and payable and the
Lender may terminate its obligation to make Revolving Loans, all without
presentment, demand,


                                       31
<PAGE>   37

protest or notice of any kind. The Lender shall promptly
advise the Borrower of any such declaration, but failure to do so shall not
impair the effect of such declaration.

                               SECTION 11: GENERAL

         11.1 Waiver; Amendments. No delay on the part of the Lender in the
exercise of any right, power or remedy shall operate as a waiver thereof, nor
shall any single or partial exercise by any of them of any right, power or
remedy preclude other or further exercise thereof, or the exercise of any other
right, power or remedy. No amendment, modification or waiver of, or consent with
respect to, any provision of this Agreement or any Note shall in any event be
effective unless the same shall be in writing and signed and delivered by the
Lender and then any such amendment, modification, waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

         11.2 Notices. All notices hereunder shall be in writing (including
facsimile transmission) and shall be sent to the applicable party at its address
shown on Schedule 11.2 or at such other address as such party may, by written
notice received by the other parties, have designated as its address for such
purpose. Notices sent by facsimile transmission shall be deemed to have been
given when sent; notices sent by mail shall be deemed to have been given three
Business Days after the date when sent by registered or certified mail, postage
prepaid; and notices sent by hand delivery or overnight courier service shall be
deemed to have been given when received.

         11.3 Costs, Expenses and Taxes. The Borrower agrees to pay on demand
all reasonable out-of-pocket costs and expenses of the Lender (including the
reasonable fees and charges of counsel for the Lender and of local counsel, if
any, who may be retained by said counsel) in connection with the preparation,
execution, syndication, delivery and administration of this Agreement, the other
Loan Documents and all other documents provided for herein or delivered or to be
delivered hereunder or in connection herewith (including any amendments,
supplements or waivers to any Loan Documents), and all reasonable out-of-pocket
costs and expenses (including reasonable attorneys' fees, court costs and other
legal expenses and allocated costs of staff counsel) incurred by the Lender in
connection with the enforcement of this Agreement, the other Loan Documents or
any such other documents. In addition, the Borrower agrees to pay, and to save
the Lender harmless from all liability for, any stamp or other taxes (excluding
income taxes and franchise taxes based on net income) that may be payable in
connection with the execution and delivery of this Agreement, the borrowings
hereunder, the issuance of the Notes or the execution and delivery of any other
Loan Document or any other document provided for herein or delivered or to be
delivered hereunder or in connection herewith. All obligations provided for in
this Section 11.3 shall survive repayment of the Loans and any termination of
this Agreement.

         11.4 Governing Law; Severability. This Agreement shall be a contract
made under and governed by the internal laws of the State of Illinois. Whenever
possible each provision of this Agreement shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Agreement shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Agreement. All obligations of the Borrower and rights of the Lender expressed
herein or in any other Loan Document shall be in addition to and not in
limitation of those provided by applicable law.


                                       32
<PAGE>   38

         11.5 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts and
each such counterpart shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Agreement.

         11.6 Successors and Assigns. This Agreement shall be binding upon the
Borrower, the Lender and their respective successors and assigns, and shall
inure to the benefit of the Borrower and the Lender and the successors and
assigns of the Lender. If the Lender transfers or assigns any portion of its
rights under this Agreement to any Person then the Lender must transfer such
corresponding portion of STEP deposits made by the State of Illinois Treasury
Department to such assignee or transferee.

         11.7 Indemnification by the Borrower. In consideration of the execution
and delivery of this Agreement by the Lender and the agreement to make the Loans
under this Agreement, the Borrower hereby agrees to indemnify, exonerate and
hold the Lender and each of the officers, directors, employees, Affiliates and
agents of the Lender (each a "Lender Party") free and harmless from and against
any and all actions, causes of action, suits, losses, liabilities, damages and
expenses, including reasonable attorneys' fees and charges and allocated costs
of staff counsel (collectively, the "Indemnified Liabilities"), incurred by the
Lender Parties or any of them as a result of, or arising out of, or relating to
(i) any tender offer, merger, purchase of stock, purchase of assets (including,
without limitation, the Acquisition) or other similar transaction financed or
proposed to be financed in whole or in part, directly or indirectly, with the
proceeds of any of the Loans, (ii) the use, handling, release, emission,
discharge, transportation, storage, treatment or disposal of any hazardous
substance at any property owned or leased by the Borrower or any Subsidiary,
(iii) any violation of any Environmental Laws with respect to conditions at any
property owned or leased by the Borrower or any Subsidiary or the operations
conducted thereon, (iv) the investigation, cleanup or remediation of offsite
locations at which the Borrower or any Subsidiary or their respective
predecessors are alleged to have directly or indirectly disposed of hazardous
substances or (v) the execution, delivery, performance or enforcement of this
Agreement or any other Loan Document by any of the Lender Parties, except for
any such Indemnified Liabilities arising on account of any the Lender Party's
gross negligence or willful misconduct. If and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Borrower hereby agrees to
make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under applicable law. Nothing set
forth above shall be construed to relieve the Lender Party from any obligation
it may have under this Agreement. All obligations provided for in this Section
11.7 shall survive repayment of the Loans, any foreclosure under, or any
modification, release or discharge of any or all of the Loan Documents and any
termination of this Agreement.

         11.8 FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT, THE
NOTES OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN
THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED STATES DISTRICT COURT FOR
THE NORTHERN DISTRICT OF ILLINOIS. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY
SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE
UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE
PURPOSE OF ANY SUCH LITIGATION

PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR
WITHOUT THE STATE OF ILLINOIS. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH
COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT
IN AN INCONVENIENT FORUM. TO THE EXTENT THAT THE BORROWER HAS OR HEREAFTER MAY
ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS
(WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN
AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE
BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS
UNDER THIS AGREEMENT, THE NOTE AND THE OTHER LOAN DOCUMENTS.

         11.9 WAIVER OF JURY TRIAL. EACH OF THE BORROWER AND THE LENDER HEREBY
WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR
DEFEND ANY RIGHTS UNDER THIS AGREEMENT, THE NOTES, ANY OTHER LOAN DOCUMENT AND

FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY
BANKING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, AND
AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT
BEFORE A JURY.

         11.10 Amendment and Restatement. This Agreement amends, restates and
supersedes in full the terms and provisions of the Existing Credit Agreement.
The execution and delivery of this Agreement and the other Loan Documents are
not intended and should not be construed (i) to deem the Borrower to have repaid
or otherwise discharged any amount of principal of or interest on the Existing

                          FORM OF SOLVENCY CERTIFICATE

         Reference is made to the Credit Agreement dated as of March 29, 2000
(as amended or otherwise modified from time to time, the "Credit Agreement"),
between Cabot Microelectronics Corporation, a Delaware corporation (the
"Borrower"), and LaSalle Bank National Association, a national banking
association (the "Lender"). Capitalized terms used in this certificate and not
otherwise defined have the meanings assigned to such terms in the Credit
Agreement.

         The undersigned certifies to the Lender that he or she is a duly
elected, qualified and acting Responsible Officer of the Borrower and further
certifies as follows:

         1. The Borrower has furnished the undersigned with a true, complete and
executed copy of the Credit Agreement as in effect on the date of this
certificate, and the undersigned has reviewed the Credit Agreement in its
entirety.

         2. The undersigned is familiar with all of the Borrower's business and
financial affairs, including, without limitation, all of the matters described
in this certificate.

         3. As of the date of this certificate, the Borrower is "solvent," and
the Borrower's incurrence of its obligations under the Credit Agreement will not

is "solvent" if:

         (a)      its assets exceed its liabilities;

         (b)      it is able to pay its debts as they mature;

         (c)      it owns property with fair salable value (including intangible
                  assets) greater than the amount required to pay its debts; and

         (d)      it has capital sufficient to carry on its business as then
                  constituted.
