("WEI"), Lockhart Industries, Inc., a California corporation ("Lockhart"),

Incorporated, a Delaware corporation ("Malco") and Uni-Star Industries, Inc., a
Delaware corporation ("Uni-Star", and together with WEI, Lockhart, WEC, Malco
and Uni-Star, each a "Borrower" and collectively, a "Borrowers").

                             W I T N E S S E T H:

    WHEREAS, Borrowers have requested that Lender enter into certain financing
arrangements with Borrowers pursuant to which Lender will, subject to the terms
and conditions set forth herein, make loans and provide other financial
accommodations to Borrowers; and

    WHEREAS, Lender is willing to make such loans and provide such financial
accommodations on the terms and conditions set forth herein;

    NOW, THEREFORE, in consideration of the mutual conditions and agreements set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

1.  DEFINITIONS

    All terms used herein which are defined in Article 1 or Article 9 of the
Uniform Commercial Code shall have the meanings given therein unless otherwise
defined in this Agreement.  All references to the plural herein shall also mean
the singular and to the singular shall also mean the plural unless the context
otherwise requires.  All references to Borrower, Borrowers and Lender pursuant
to the definitions set forth in the recitals hereto, or to any other person
herein, shall include their respective successors and assigns.  The words
"hereof", "herein", "hereunder", "this Agreement" and words of similar import
when used in this Agreement shall refer to this Agreement as a whole and not any
particular provision of this Agreement and as this Agreement now exists or may
hereafter be amended, modified, supplemented, extended, renewed, restated or
replaced.  The word "including" when used in this Agreement shall mean
"including, without limitation".  An Event of Default shall exist or continue or
be continuing until such Event of Default is waived in accordance with Section
11.3 or is cured in a manner satisfactory to Lender, if such Event of Default is
capable of being cured as determined by Lender.  Any accounting term used herein
unless otherwise defined in this Agreement shall have the meanings customarily
given to such term in accordance with GAAP.  For purposes of this Agreement, the
following terms shall have the respective meanings given to them below:

                                                                               1
<PAGE>

     1.1 "Accounts" shall mean all present and future rights of Borrowers to
payment for goods sold or leased or for services rendered, which are not
evidenced by instruments or chattel paper, and whether or not earned by
performance.

     1.2 "Adjusted Eurodollar Rate" shall mean, with respect to each Interest
Period for any Eurodollar Rate Loan, the rate per annum (rounded upwards, if
necessary, to the next one-sixteenth (1/16) of one (1%) percent) determined by
dividing (a) the Eurodollar Rate for such Interest Period by (b) a percentage
equal to: (i) one (1) minus (ii) the Reserve Percentage. For purposes hereof,
"Reserve Percentage" shall mean the reserve percentage, expressed as a decimal,
prescribed by any United States or foreign banking authority for determining the
reserve requirement which is or would be applicable to deposits of United States
dollars in a non-United States or an international banking office of Reference
Bank used to fund a Eurodollar Rate Loan or any Eurodollar Rate Loan made with
the proceeds of such deposit, whether or not the Reference Bank actually holds
or has made any such deposits or loans. The Adjusted Eurodollar Rate shall be
adjusted on and as of the effective day of any change in the Reserve Percentage.

     1.3 "Adjusted Net Worth" shall mean as to any Person, at any time, in
accordance with GAAP (except as otherwise specifically set forth below), on a
consolidated basis for such Person and its subsidiaries (if any), the amount
equal to: (a) the difference between: (i) the aggregate net book value of all
assets of such Person and its subsidiaries, calculating the book value of
inventory for this purpose on a first-in-first-out basis, after deducting from
such book values all appropriate reserves in accordance with GAAP (including all
reserves for doubtful receivables, obsolescence, depreciation and amortization)
and (ii) the aggregate amount of the indebtedness and other liabilities of such
Person and its subsidiaries (including tax and other proper accruals) plus (b)
indebtedness of such Person and its subsidiaries which is subordinated in right
of payment to the full and final payment of all of the Obligations on terms and
conditions acceptable to Lender.

     1.4 "Appraised Value" shall mean, as determined by Lender in good faith,
with respect to the Inventory, the appraised orderly liquidation value thereof
as set forth in an appraisal of such Inventory prepared by an independent
appraiser acceptable to Lender and in form and substance satisfactory to Lender.

     1.5 "Availability Reserves" shall mean, as of any date of determination,
such amounts as Lender may from time to time establish and revise in good faith
reducing the amount of Revolving Loans which would otherwise be available to
Borrowers under the lending formula(s) provided for herein: (a) to reflect
events, conditions, contingencies or risks which, as determined by Lender in
good faith, do or are reasonably likely to affect either (i) the Collateral or
any other property which is security for the Obligations or its value, (ii) the
assets, business or prospects of Borrowers or any Obligor or (iii) the security
interests and other rights of Lender in the Collateral (including the
enforceability, perfection and priority thereof) or (b) to reflect Lender's good
faith belief that any collateral report or financial information furnished by or
on behalf of any Borrower or any Obligor to Lender is or may have been
incomplete, inaccurate or misleading in any material respect or (c) in respect
of any state of facts which Lender determines in good faith constitutes an Event
of Default or is reasonably likely, with notice or passage of time or both, to
constitute an Event of Default.

                                                                               2

     1.7 "Business Day" shall mean any day other than a Saturday, Sunday, or
other day on which commercial banks are authorized or required to close under
the laws of the State of New York or the State of North Carolina, and a day on
which the Reference Bank and Lender are open for the transaction of business,
except that if a determination of a Business Day shall relate to any Eurodollar
Rate Loans, the term Business Day shall also exclude any day on which banks are
closed for dealings in dollar deposits in the London interbank market or other
applicable Eurodollar Rate market.

     1.8 "Change in Control" shall be deemed to have occurred at such time as
(i) a "person" or "Group" (within the meaning of Section 13(d) or 14(d)(2) of
the Securities Exchange Act of 1934, as amended, becomes the beneficial owner
(as defined in Rule 13a-3 of the Securities Exchange Act of 1934, as amended),
directly or indirectly, of more than thirty (30%) percent of the total voting
power of all classes of stock of Parent entitled to vote in the election of
directors (provided that such person or Group was not the beneficial owner of at
least such percentage of such stock on the date of this Agreement), or (ii) a
change in the Board of Directors of Parent occurs in which individuals who
constituted the Board of Directors at the beginning of the two year period
immediately preceding such change (together with any other director whose
nomination for election by the shareholders of Parent was approved by a vote of
at least seventy-five (75%) percent of the directors at the beginning of such
period or whose nomination and election was previously so approved) cease for
any reason to constitute a majority of directors therein office.

     the lending formula(s), Lender may consider events, conditions,
     contingencies or risks which are also considered in determining Eligible
     Accounts, Eligible Inventory or in establishing Availability Reserves.

          (c) Except in Lender's discretion, the aggregate amount of the Loans
     outstanding at any time shall not exceed the Maximum Credit and the
     aggregate amount of Revolving Loans outstanding at any time shall not
     exceed the Revolving Loan Limit. In the event that the outstanding amount
     of any component of the Loans, or the aggregate amount of the outstanding
     Loans, exceed the amounts available under the lending formulas, the
     Revolving Loan Limit or the Maximum Credit, as applicable, such event shall
     not limit, waive or otherwise affect any rights of Lender in that
     circumstance or on any future occasions and Borrowers shall, upon demand by
     Lender, which may be made at any time or from time to time, immediately
     repay to Lender the entire amount of any such excess(es) for which payment
     is demanded.

     2.2 Intentionally Omitted.

     2.3 Term Loan. Lender is making a Term Loan to Borrowers in the original
principal amount of $5,400,000.00. The Term Loan is (a) evidenced by a Term
Promissory Note in such original principal amount duly executed and delivered by
Borrowers to Lender concurrently herewith; (b) to be repaid, together with
interest and other amounts, in accordance with this Agreement, the Term
Promissory Note, and the other Financing Agreements and (c) secured by all of
the Collateral.

     2.4 Availability Reserves. All Revolving Loans otherwise available to
Borrowers pursuant to the lending formulas and subject to the Maximum Credit,
Revolving Loan Limit and other applicable limits hereunder shall be subject to
Lender's continuing right to establish and revise Availability Reserves. In
addition to the foregoing, on the date hereof the Lender has established a
$500,000.00 initial Availability Reserve which shall be released, so long as no
Event of Default or event or condition which with notice or passage of time or
both might constitute an Event of Default exists or has recurred and is
continuing, five (5) business days after Lender's receipt of the Borrower's
audited financial statements for their fiscal year ending October 31, 1999
pursuant to Section 9.6(a)(ii) hereof that evidence that Borrowers' earnings
before provision for income taxes and excluding all extraordinary and
nonrecurring items, determined in accordance with GAAP, equals or exceeded
$1.00.

     2.5 Equipment Acquisition Facility.

          (a) Subject to, and upon the terms and conditions contained herein,
     Lender agrees to make Equipment Loans to Borrowers from time to time, up to
     the amount equal seventy-five (75%) percent of the Hard Cost of Eligible
     Equipment acquired with such Equipment

                                                                              12
<PAGE>

     Loan, provided that the outstanding principal amount of all Equipment Loans
     shall not exceed $1,000,000.00 for the period of the Borrowers' fiscal year
     ending October 31, 1999. An additional $2,000,000.00 of Equipment Loans
     will be made available to Borrowers if their annual audited financial
     statements for their fiscal year ending October 31, 1999 or for any fiscal
     year thereafter pursuant to Section 9.6(a)(ii) hereof evidence that
     Borrowers' earnings before provision for income taxes and excluding all
     extraordinary and nonrecurring items, determined in accordance with GAAP,
     equal or exceed $1.00. Lender may, in its good faith discretion, from time
     to time upon written notice to Borrowers reduce the lending formula with
     respect to Equipment Loans requested after such notice to the extent that
     Lender determines in good faith that the liquidation value of the Eligible
     Equipment or any portion thereof, has decreased or the nature and quality
     of the Eligible Equipment has deteriorated.

          (b) Each Equipment Loan requested by Borrowers hereunder shall be in a
     minimum amount of $50,000. Each request by Borrowers for an Equipment Loan
     shall be accompanied by copies of all purchase orders, invoices and other
     documentation relating to the Eligible Equipment to be purchased with the
     proceeds of such Equipment Loan, including a list and description of the
     Eligible Equipment (by model, make, manufacturer, serial no. (if available)
     and/or such other identifying information as may be required by Lender) and
     such other information and documents as may be reasonably requested by
     Lender. Each Equipment Loan shall be (a) evidenced by an Equipment Loan
     Promissory Note substantially in the form attached as Exhibit B hereto,
     completed, executed and delivered by Borrowers to Lender (in a manner
     satisfactory to Lender) prior to the making of any Equipment Loan or by the
     records and loan accounts maintained by Lender; (b) repaid, together with
     interest and other amounts, in accordance with this Agreement, the
     Equipment Loan Promissory Note, and the other Financing Agreements and (c)
     secured by a first and only security interest on the acquired Equipment and
     by all the other Collateral. Borrowers shall deliver to Lender upon request
     evidence of full payment for all Eligible Equipment acquired with the
     proceeds of an Equipment Loan and the absence of liens thereon. The
     principal amount of each Equipment Loan shall be repaid in equal
     consecutive monthly payments, payable on the first day of each calendar
     month, commencing on the first such day to occur after the date each such
     Loan is made. The principal amount shall be amortized over a sixty (60)
     month period and the outstanding principal balance thereof and all accrued
     and unpaid interest, fees and charges shall be due and payable on the first
     to occur of (a) the election of Lender upon and following an Event of
     Default and (b) the date of termination or nonrenewal of this Agreement.
     The making of each Equipment Loan shall be subject to the terms of this
     provision, the conditions precedent of Section 4.2 hereof and to the
     further condition that the Borrowers' financial statements delivered to
     Lender pursuant to Section 9.6(a)(i) hereof shall evidence that for the
     prior six consecutive calendar months Borrowers had for such six month
     period earnings before provision for income taxes and exclusive of
     extraordinary and nonrecurring items, as determined in accordance with
     GAAP, of not less than $1.00. Interest on the Equipment Loans shall be
     computed and paid in accordance with Section 3.1 hereof.

     2.6 Appointment of Agent. Borrowers hereby irrevocably appoint and
constitute Alpha, or any other Borrower selected by the Lender from time to time
upon and during the continuance of an Event of Default in the Lender's sole and
exclusive discretion (a "Replacement Agent"), as their agent to request Loans
and to take all actions required or permitted hereunder in the name of and on
behalf of each and all the Borrowers including, without limitation, requesting
the

                                                                              13
<PAGE>

conversion to or continuation of Eurodollar Rate Loans under Section 3.1(d)
hereof and any Equipment Loans. This appointment shall include, without implied
limitation, the designation of Alpha (or the Replacement Agent) as the agent of
the Borrowers to furnish all notices to the Lender including, without
limitation, any notice under subsection 4.2.2 hereof, and to receive all notices
from the Lender including, without limitation, all statements of Loan Account(s)
under this Agreement. This appointment may not be terminated while this
Agreement is in effect or the Obligations are outstanding without the prior
written consent of Lender. Loans may be made by Lender to Alpha (or the
Replacement Agent) for the benefit of the Borrowers and shall be disbursed by
Alpha (or the Replacement Agent) to the other Borrowers in accordance with the
lending formulas under Section 1.1, and the Net Amount of the Eligible Accounts,
the Appraisal Value of Eligible Inventory of each Borrower and the loan formulas
applicable thereto as provided herein and the Hard Cost of Eligible Equipment
and the advance rate applicable to Eligible Equipment. At any time the Lender
may, in its discretion, disburse Loans to the Borrowers directly (i.e., not
first to Alpha or any Replacement Agent) or as otherwise provided in this
Agreement.

3.  INTEREST AND FEES

     3.1 Interest.

          (a) Borrowers shall pay to Lender interest on the outstanding
     principal amount of the non-contingent Obligations at the Interest Rate.
     All interest accruing hereunder on and after the date of any Event of
     Default or termination or non-renewal hereof shall be payable on demand.

          (b) Borrowers may from time to time request that Prime Rate Loans be
     converted to Eurodollar Rate Loans or that any existing Eurodollar Rate
     Loans continue for an additional Interest Period. Such request from
     Borrowers shall specify the amount of the Prime Rate Loans which will
     constitute Eurodollar Rate Loans (subject to the limits set forth below)
     and the Interest Period to be applicable to such Eurodollar Rate Loans.
     Subject to the terms and conditions contained herein, three (3) Business
     Days after receipt by Lender of such a request from Borrowers, such Prime
     Rate Loans shall be converted to Eurodollar Rate Loans or such Eurodollar
     Rate Loans shall continue, as the case may be, provided, that, (i) no Event
     of Default, or event which with notice or passage of time or both would
     constitute an Event of Default exists or has occurred and is continuing,
     (ii) no party hereto shall have sent any notice of termination or non-
     renewal of this Agreement, (iii) Borrowers shall have complied with such
     customary procedures as are established by Lender and specified by Lender
     to Borrowers from time to time for requests by Borrowers for Eurodollar
     Rate Loans, (iv) no more than four (4) Interest Periods may be in effect at
     any one time, (v) the aggregate amount of the Eurodollar Rate Loans must be
     in an amount not less than $5,000,000 or an integral multiple of $1,000,000
     in excess thereof, (vi) the maximum amount of the Eurodollar Rate Loans at
     any time requested by Borrowers shall not exceed the amount equal to (A)
     the principal amount of the Term Loan and Equipment Loans which it is
     anticipated will be outstanding as of the last day of the applicable
     Interest Period plus (B) eighty (80%) percent of the lowest principal
     amount of the Revolving Loans which it is anticipated will be outstanding
     during the applicable Interest Period, in each case as determined by Lender
     (but with no obligation of Lender to make such Revolving Loans) and (vii)
     Lender shall

                                                                              14
<PAGE>

     have determined that the Interest Period or Adjusted Eurodollar Rate is
     available to Lender through the Reference Bank and can be readily
     determined as of the date of the request for such Eurodollar Rate Loan by
     Borrowers. Any request by Borrowers to convert Prime Rate Loans to
     Eurodollar Rate Loans or to continue any existing Eurodollar Rate Loans
     shall be irrevocable. Notwithstanding anything to the contrary contained
     herein, Lender and Reference Bank shall not be required to purchase United
     States Dollar deposits in the London interbank market or other applicable
     Eurodollar Rate market to fund any Eurodollar Rate Loans, but the
     provisions hereof shall be deemed to apply as if Lender and Reference Bank
     had purchased such deposits to fund the Eurodollar Rate Loans.

          (c) Any Eurodollar Rate Loans shall automatically convert to Prime
     Rate Loans upon the last day of the applicable Interest Period, unless
     Lender has received and approved a request to continue such Eurodollar Rate
     Loan at least three (3) Business Days prior to such last day in accordance
     with the terms hereof. Any Eurodollar Rate Loans shall, at Lender's option,
     upon notice by Lender to Borrowers, convert to Prime Rate Loans in the
     event that (i) an Event of Default or event which, with the notice or
     passage of time, or both, would constitute an Event of Default, shall
     exist, (ii) this Agreement shall terminate or not be renewed, or (iii) the
     aggregate principal amount of the Prime Rate Loans which have previously
     been converted to Eurodollar Rate Loans or existing Eurodollar Rate Loans
     continued, as the case may be, at the beginning of an Interest Period shall
     at any time during such Interest Period exceed either (A) the aggregate
     principal amount of the Loans then outstanding, or (B) the sum of the then
     outstanding principal amount of the Term Loan plus the Revolving Loans then
     available to Borrowers under Section 2 hereof. Borrowers shall pay to
     Lender, upon demand by Lender (or Lender may, at its option, charge any
     loan account of Borrowers) any amounts required to compensate Lender, the
     Reference Bank or any participant with Lender for any loss (including loss
     of anticipated profits), cost or expense incurred by such person, as a
     result of the conversion of Eurodollar Rate Loans to Prime Rate Loans
     pursuant to any of the foregoing.

          (d) Interest shall be payable by Borrowers to Lender monthly in
     arrears not later than the first day of each calendar month and shall be
     calculated on the basis of a three hundred sixty (360) day year and actual
     days elapsed. The interest rate on non-contingent Obligations (other than
     Eurodollar Rate Loans) shall increase or decrease by an amount equal to
     each increase or decrease in the Prime Rate effective on the first day of
     the month after any change in such Prime Rate is announced based on the
     Prime Rate in effect on the last day of the month in which any such change
     occurs. In no event shall charges constituting interest payable by
     Borrowers to Lender exceed the maximum amount or the rate permitted under
     any applicable law or regulation, and if any such part or provision of this
     Agreement is in contravention of any such law or regulation, such part or
     provision shall be deemed amended to conform thereto.

     3.2 Closing Fee. Borrowers shall pay to Lender as a closing fee the amount
of $189,000.00, which shall be fully earned as of the date hereof and payable in
two installments of $169,000 on the date hereof and $20,000 at such time as the
additional $2,000,000 of the Equipment Acquisition Facility is made available to
Borrower hereunder.

     3.3 Intentionally Omitted.

                                                                              15
<PAGE>

     3.4 Servicing Fee. Borrowers shall pay to Lender monthly a servicing fee in
an amount equal to $2,000.00 in respect of Lender's services for each month (or
part thereof) while this Agreement remains in effect and for so long thereafter
as any of the Obligations are outstanding, which fee shall be fully earned as of
and payable in advance on the date hereof and on the first day of each month
hereafter.

     3.5 Unused Line Fee. Borrowers shall pay to Lender monthly an unused line
fee at a rate equal to one half of one (.50%) percent per annum calculated upon
the amount by which the Revolving Loan Limit exceeds the average daily principal
balance of the outstanding Revolving Loans during the immediately preceding
month (or part thereof) while this Agreement is in effect and for so long
thereafter as any of the Obligations are outstanding, which fee shall be payable
on the first day of each month in arrears.

     3.6 Changes in Laws and Increased Costs of Loans.

          (a) Notwithstanding anything to the contrary contained herein, all
     Eurodollar Rate Loans shall, upon notice by Lender to Borrowers, convert to
     Prime Rate Loans in the event that (i) any change in applicable law or
     regulation (or the interpretation or administration thereof) shall either
     (A) make it unlawful for Lender, Reference Bank or any participant to make
     or maintain Eurodollar Rate Loans or to comply with the terms hereof in
     connection with the Eurodollar Rate Loans, or (B) shall result in the
     increase in the costs to Lender, Reference Bank or any participant of
     making or maintaining any Eurodollar Rate Loans by an amount deemed by
     Lender to be material, or (C) reduce the amounts received or receivable by
     Lender in respect thereof, by an amount deemed by Lender to be material or
     (ii) the cost to Lender, Reference Bank or any participant of making or
     maintaining any Eurodollar Rate Loans shall otherwise increase by an amount
     deemed by Lender to be material. Borrowers shall pay to Lender, upon demand
     by Lender (or Lender may, at its option, charge any loan account of
     Borrower) any amounts required to compensate Lender, the Reference Bank or
     any participant with Lender for any loss (including loss of anticipated
     profits), cost or expense incurred by such person as a result of the
     foregoing, including, without limitation, any such loss, cost or expense
     incurred by reason of the liquidation or reemployment of deposits or other
     funds acquired by such person to make or maintain the Eurodollar Rate Loans
     or any portion thereof. A certificate of Lender setting forth the basis for
     the determination of such amount necessary to compensate Lender as
     aforesaid shall be delivered to Borrowers and shall be conclusive, absent
     manifest error.

          (b) If any payments or prepayments in respect of the Eurodollar Rate
     Loans are received by Lender other than on the last day of the applicable
     Interest Period (whether pursuant to acceleration, upon maturity or
     otherwise), including any payments pursuant to the application of
     collections under Section 6.3 or any other payments made with the proceeds
     of Collateral, Borrowers shall pay to Lender upon demand by Lender (or
     Lender may, at its option, charge any loan account of Borrowers) any
     amounts required to compensate Lender, the Reference Bank or any
     participant with Lender for any additional loss (including loss of
     anticipated profits), cost or expense incurred by such person as a result
     of such prepayment or payment, including, without limitation, any loss,
     cost or expense incurred by reason of the liquidation or reemployment of
     deposits or other funds acquired by such person to make or maintain such
     Eurodollar Rate Loans or any portion thereof.

                                                                              16

                                                                              19

such Equipment is not intended to constitute Eligible Equipment for the purpose
of the making of any Equipment Loan.

6.  COLLECTION AND ADMINISTRATION

     6.1 Borrowers' Loan Account. Lender shall maintain one or more loan
account(s) on its books in which shall be recorded (a) all Loans, and other
Obligations and the Collateral, (b) all payments made by or on behalf of
Borrowers and (c) all other appropriate debits and credits as provided in this
Agreement, including fees, charges, costs, expenses and interest. All entries in
the loan account(s) shall be made in accordance with Lender's customary
practices as in effect from time to time.

     6.2 Statements. Lender shall render to Borrowers each month a statement
setting forth the balance in the Borrowers' loan account(s) maintained by Lender
for Borrowers pursuant to the provisions of this Agreement, including principal,
interest, fees, costs and expenses. Each such statement shall be subject to
subsequent adjustment by Lender but shall, absent manifest errors or omissions,
be considered correct and deemed accepted by Borrowers and conclusively binding
upon Borrowers as an account stated except to the extent that Lender receives a
written notice from Borrowers of any specific exceptions of Borrowers thereto
within forty-five (45) days after the date such statement has been mailed by
Lender. Until such time as Lender shall have rendered to Borrowers a written
statement as provided above, the balance in Borrowers' loan account(s) shall be
presumptive evidence of the amounts due and owing to Lender by Borrowers.

     6.3 Collection of Accounts.

          (a) Borrowers shall establish and maintain, at their expense, blocked
     accounts or lockboxes and related blocked accounts (in either case,
     "Blocked Accounts"), as Lender may specify, with such banks as are
     acceptable to Lender into which Borrowers shall promptly deposit and direct
     its account debtors to directly remit all payments on Accounts and all
     payments constituting proceeds of Inventory or other Collateral in the
     identical form in which such payments are made, whether by cash, check or
     other manner. The banks at which the Blocked Accounts are established shall
     enter into an agreement, in form and substance satisfactory to Lender,
     providing that all items received or deposited in the Blocked Accounts are
     the property of Lender, that the depository bank has no lien upon, or right
     to setoff against, the Blocked Accounts, the items received for deposit
     therein, or the funds from time to time on deposit therein and that the
     depository bank will wire, or otherwise transfer, in immediately available
     funds, on a daily basis, all funds received or deposited into the Blocked
     Accounts to such bank account of Lender as Lender may from time to time
     designate for such purpose ("Payment Account"). Borrowers agree that all
     payments made to such Blocked Accounts or other funds received and
     collected by Lender, whether on the Accounts or as proceeds of Inventory or
     other Collateral or otherwise shall be the property of Lender to the extent
     of the aggregate amount of the Obligations outstanding from time to time.

          (b) For purposes of calculating the amount of the Loans available to
     Borrowers, such payments will be applied (conditional upon final
     collection) to the Obligations on the business day of receipt by Lender of
     immediately available funds in the Payment Account

                                                                              20
<PAGE>

     provided such payments and notice thereof are received in accordance with
     Lender's usual and customary practices as in effect from time to time and
     within sufficient time to credit Borrowers' loan account on such day, and
     if not, then on the next business day. For the purposes of calculating
     interest on the Obligations, such payments or other funds received will be
     applied (conditional upon final collection) to the Obligations one (1)
     business day(s) following the date of receipt of immediately available
     funds by Lender in the Payment Account provided such payments or other
     funds and notice thereof are received in accordance with Lender's usual and
     customary practices as in effect from time to time and within sufficient
     time to credit Borrowers' loan account on such day, and if not, then on the
     next business day.

          (c) Borrowers and all of their affiliates, subsidiaries, shareholders,
     directors, employees or agents shall, acting as trustee for Lender,
     receive, as the property of Lender, any monies, checks, notes, drafts or
     any other payment relating to and/or proceeds of Accounts or other
     Collateral which come into their possession or under their control and
     immediately upon receipt thereof, shall deposit or cause the same to be
     deposited in the Blocked Accounts, or remit the same or cause the same to
     be remitted, in kind, to Lender. In no event shall the same be commingled
     with Borrowers' own funds. Borrowers agree to reimburse Lender on demand
     for any amounts owed or paid to any bank at which a Blocked Account is
     established or any other bank or person involved in the transfer of funds
     to or from the Blocked Accounts arising out of Lender's payments to or
     indemnification of such bank or person. The obligation of Borrowers to
     reimburse Lender for such amounts pursuant to this Section 6.3 shall
     survive the termination or non-renewal of this Agreement.

     6.4 Payments. All Obligations shall be payable to the Payment Account as
provided in Section 6.3 or such other place as Lender may designate from time to
time. Lender may apply payments received or collected from Borrowers or for the
account of Borrowers (including the monetary proceeds of collections or of
realization upon any Collateral) to such of the Obligations, whether or not then
due, in such order and manner as Lender determines. At Lender's option, all
principal, interest, fees, costs, expenses and other charges provided for in
this Agreement or the other Financing Agreements may be charged directly to the
loan account(s) of Borrowers. Borrowers shall make all payments to Lender on the
Obligations free and clear of, and without deduction or withholding for or on
account of, any setoff, counterclaim, defense, duties, taxes, levies, imposts,
fees, deductions, withholding, restrictions or conditions of any kind. If after
receipt of any payment of, or proceeds of Collateral applied to the payment of,
any of the Obligations, Lender is required to surrender or return such payment
or proceeds to any Person for any reason, then the Obligations intended to be
satisfied by such payment or proceeds shall be reinstated and continue and this
Agreement shall continue in full force and effect as if such payment or proceeds
had not been received by Lender. Borrowers shall be liable to pay to Lender, and
do hereby indemnify and hold Lender harmless for the amount of any payments or
proceeds surrendered or returned. This Section 6.4 shall remain effective
notwithstanding any contrary action which may be taken by Lender in reliance
upon such payment or proceeds. This Section 6.4 shall survive the payment of the
Obligations and the termination or non-renewal of this Agreement.

     6.5 Authorization to Make Loans. Lender is authorized to make the Loans
based upon telephonic or other instructions received from anyone purporting to
be an officer of Alpha

                                                                              21
<PAGE>

identified on the Information Certificate for Alpha attached hereto, as the same
may be amended from time to time, as agent for the Borrowers, or from anyone
purporting to be an officer of and to be authorized under the Information
Certificate of Replacement Agent or of any other Borrower or other authorized
person or, at the discretion of Lender, if such Loans are necessary to satisfy
any Obligations. All requests for Loans hereunder shall specify the date on
which the requested advance is to be made (which day shall be a business day)
and the amount of the requested Loan. Requests received after 11:00 a.m. Boston,
Massachusetts time on any day shall be deemed to have been made as of the
opening of business on the immediately following business day. All Loans under
this Agreement shall be conclusively presumed to have been made to, and at the
request of and for the benefit of, Borrowers when deposited to the credit of
Borrowers or otherwise disbursed or established in accordance with the
instructions of Alpha, as agent for the Borrowers, or of the Replacement Agent
or of any other Borrower or in accordance with the terms and conditions of this
Agreement.

     6.6 Use of Proceeds. Borrowers shall use the initial proceeds of the Loans
provided by Lender to Borrowers hereunder only for: (a) payments to each of the
persons listed in the disbursement direction letter furnished by Borrowers to
Lender on or about the date hereof and (b) costs, expenses and fees in
connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Financing Agreements. All other Loans made by Lender to
Borrowers pursuant to the provisions hereof shall be used by Borrowers only for
general operating, working capital and other proper corporate purposes of
Borrowers not otherwise prohibited by the terms hereof. None of the proceeds
will be used, directly or indirectly, for the purpose of purchasing or carrying
any margin security or for the purposes of reducing or retiring any indebtedness
which was originally incurred to purchase or carry any margin security or for
any other purpose which might cause any of the Loans to be considered a "purpose
credit" within the meaning of Regulation U of the Board of Governors of the
Federal Reserve System, as amended.

7.  COLLATERAL REPORTING AND COVENANTS

     7.1 Collateral Reporting. Borrowers shall provide Lender with the following
documents in a form satisfactory to Lender: (a) on a regular basis as required
by Lender, a schedule of Accounts, sales made, credits issued and cash received;
(b) on a monthly basis or more frequently as Lender may request, (i) perpetual
inventory reports, (ii) inventory reports by category and (iii) agings of
accounts payable, (c) upon Lender's request, (i) copies of customer statements
and credit memos, remittance advices and reports, and copies of deposit slips
and bank statements, (ii) copies of shipping and delivery documents, and (iii)
copies of purchase orders, invoices and delivery documents for Inventory and
Equipment acquired by any Borrower; (d) agings of accounts receivable on a
monthly basis or more frequently as Lender may request; and (e) such other
reports as to the Collateral as Lender shall request from time to time. If any
of Borrowers' records or reports of the Collateral are prepared or maintained by
an accounting service, contractor, shipper or other agent, each Borrower hereby
irrevocably authorizes such service, contractor, shipper or agent to deliver
such records, reports, and related documents to Lender and to follow Lender's
instructions with respect to further services at any time that an Event of
Default exists or has occurred and is continuing.

                                                                              22
<PAGE>

     7.2 Accounts Covenants.

          (a) Borrowers shall notify Lender promptly of: (i) any material delay
     in any Borrower's performance of any of its obligations to any account
     debtor or the assertion of any claims, offsets, defenses or counterclaims
     by any account debtor, or any disputes with account debtors, or any
     settlement, adjustment or compromise thereof, (ii) all material adverse
     information relating to the financial condition of any account debtor and
     (iii) any event or circumstance which, to any Borrower's knowledge would
     cause Lender to consider any then existing Accounts as no longer
     constituting Eligible Accounts. No credit, discount, allowance or extension
     or agreement for any of the foregoing shall be granted to any account
     debtor without Lender's consent, except in the ordinary course of a
     Borrower's business in accordance with practices and policies as disclosed
     by Borrowers from time to time in writing to Lender. So long as no Event of
     Default exists or has occurred and is continuing, Borrowers shall settle,
     adjust or compromise any claim, offset, counterclaim or dispute with any
     account debtor. At any time that an Event of Default exists or has occurred
     and is continuing, Lender shall, at its option and upon notice to
     Borrowers, have the exclusive right to settle, adjust or compromise any
     claim, offset, counterclaim or dispute with account debtors or grant any
     credits, discounts or allowances.

          (b) Without limiting the obligation of Borrowers to deliver any other
     information to Lender, Borrowers shall promptly report to Lender any return
     of Inventory by any one account debtor if the inventory so returned in such
     case has a value in excess of $25,000.00. At any time that Inventory is
     returned, reclaimed or repossessed, the Account (or portion thereof) which
     arose from the sale of such returned, reclaimed or repossessed Inventory
     shall not be deemed an Eligible Account to the extent of the portion
     thereof attributed to the returned, reclaimed or repossessed Inventory. In
     the event any account debtor returns Inventory when an Event of Default
     exists or has occurred and is continuing, Borrowers shall, upon Lender's
     request, (i) hold the returned Inventory in trust for Lender, (ii)
     segregate all returned Inventory from all of its other property, (iii)
     dispose of the returned Inventory solely according to Lender's
     instructions, and (iv) not issue any credits, discounts or allowances with
     respect thereto without Lender's prior written consent.

          (c) With respect to each Account: (i) the amounts shown on any invoice
     delivered to Lender or schedule thereof delivered to Lender shall be true
     and complete, (ii) no payments shall be made thereon except payments
     immediately delivered to Lender pursuant to the terms of this Agreement,
     (iii) no credit, discount, allowance or extension or agreement for any of
     the foregoing shall be granted to any account debtor except as reported to
     Lender in accordance with this Agreement and except for credits, discounts,
     allowances or extensions made or given in the ordinary course of a
     Borrower's business in accordance with practices and policies disclosed by
     Borrowers from time to time to Lender, (iv) there shall be no setoffs,
     deductions, contras, defenses, counterclaims or disputes existing or
     asserted with respect thereto except as reported to Lender in accordance
     with the terms of this Agreement, (v) none of the transactions giving rise
     thereto will violate any applicable State or Federal laws or regulations,
     all documentation relating thereto will be legally sufficient under such
     laws and regulations and all such documentation will be legally enforceable
     in accordance with its terms.

                                                                              23
<PAGE>

          (d) Lender shall have the right at any time or times, in Lender's name
     or in the name of a nominee of Lender, to verify the validity, amount or
     any other matter relating to any Account or other Collateral, by mail,
     telephone, facsimile transmission or otherwise.

          (e) Borrowers shall deliver or cause to be delivered to Lender, with
     appropriate endorsement and assignment, with full recourse to Borrowers,
     all chattel paper and instruments which any Borrower now owns or may at any
     time acquire immediately upon such Borrower's receipt thereof, except as
     Lender may otherwise agree.

          (f) Lender may, at any time or times that an Event of Default exists
     or has occurred and is continuing, (i) notify any or all account debtors
     that the Accounts have been assigned to Lender and that Lender has a
     security interest therein and Lender may direct any or all accounts debtors
     to make payment of Accounts directly to Lender, (ii) extend the time of
     payment of, compromise, settle or adjust for cash, credit, return of
     merchandise or otherwise, and upon any terms or conditions, any and all
     Accounts or other obligations included in the Collateral and thereby
     discharge or release the account debtor or any other party or parties in
     any way liable for payment thereof without affecting any of the
     Obligations, (iii) demand, collect or enforce payment of any Accounts or
     such other obligations, but without any duty to do so, and Lender shall not
     be liable for its failure to collect or enforce the payment thereof nor for
     the negligence of its agents or attorneys with respect thereto and (iv)
     take whatever other action Lender may deem necessary or desirable for the
     protection of its interests. At any time that an Event of Default exists or
     has occurred and is continuing, at Lender's request, all invoices and
     statements sent to any account debtor shall state that the Accounts and
     such other obligations have been assigned to Lender and are payable
     directly and only to Lender and Borrowers shall deliver to Lender such
     originals of documents evidencing the sale and delivery of goods or the
     performance of services giving rise to any Accounts as Lender may require.

     7.3 Inventory Covenants. With respect to the Inventory: (a) Borrowers shall
at all times maintain inventory records reasonably satisfactory to Lender,
keeping correct and accurate records itemizing and describing the kind, type,
quality and quantity of Inventory, each Borrower's cost therefor and daily
withdrawals therefrom and additions thereto; (b) Borrowers shall conduct a
physical count of the Inventory at least once each year, but at any time or
times as Lender may request on or after an Event of Default, and promptly
following such physical inventory shall supply Lender with a report in the form
and with such specificity as may be reasonably satisfactory to Lender concerning
such physical count; (c) Borrowers shall not remove any Inventory from the
locations set forth or permitted herein, without the prior written consent of
Lender, except for sales of Inventory in the ordinary course of Borrowers'
business and except to move Inventory directly from one location set forth or
permitted herein to another such location; (d) upon Lender's request, Borrowers
shall, at their expense, no more than twice in any twelve (12) month period, but
at any time or times as Lender may request on or after an Event of Default,
deliver or cause to be delivered to Lender written reports or appraisals as to
the Inventory in form, scope and methodology acceptable to Lender and by an
appraiser acceptable to Lender, addressed to Lender or upon which Lender is
expressly permitted to rely; (e) Borrowers shall produce, use, store and
maintain the Inventory with all reasonable care and caution and in accordance
with applicable standards of any insurance and in conformity with applicable
laws (including the requirements of the Federal Fair Labor Standards Act of
1938, as amended and all

                                                                              24
<PAGE>

rules, regulations and orders related thereto); (f) Borrowers assume all
responsibility and liability arising from or relating to the production, use,
sale or other disposition of the Inventory; (g) Borrowers shall not sell
Inventory to any customer on approval, or any other basis which entitles the
customer to return or may obligate any Borrower to repurchase such Inventory;
(h) Borrowers shall keep the Inventory in good and marketable condition; and (i)
Borrowers shall not, without prior written notice to Lender, acquire or accept
any Inventory on consignment or approval.

     7.4 Equipment Covenants. With respect to the Equipment: (a) upon Lender's
request, Borrowers shall, at their expense, once each year during the term of
this Agreement or at any time or times as Lender may request on or after an
Event of Default, deliver or cause to be delivered to Lender written reports or
appraisals as to the Equipment in form, scope and methodology acceptable to
Lender and by an appraiser acceptable to Lender; (b) Borrowers shall keep the
Equipment in good order, repair, running and marketable condition (ordinary wear
and tear excepted); (c) Borrowers shall use the Equipment with all reasonable
care and caution and in accordance with applicable standards of any insurance
and in conformity with all applicable laws; (d) the Equipment is and shall be
used in Borrowers' businesses and not for personal, family, household or farming
use; (e) Borrowers shall not remove any Equipment from the locations set forth
or permitted herein, except to the extent necessary to have any Equipment
repaired or maintained in the ordinary course of the business of any Borrower or
to move Equipment directly from one location set forth or permitted herein to
another such location and except for the movement of motor vehicles used by or
for the benefit of any Borrower in the ordinary course of business; (f) the
Equipment is now and shall remain personal property and Borrowers shall not
permit any of the Equipment to be or become a part of or affixed to real
property; and (g) Borrowers assume all responsibility and liability arising from
the use of the Equipment.

     7.5 Power of Attorney. Each Borrower hereby irrevocably designates and
appoints Lender (and all persons designated by Lender) as such Borrower's true
and lawful attorney-in-fact, and authorizes Lender, in each such Borrower's or
Lender's name, to: (a) at any time an Event of Default or event which with
notice or passage of time or both would constitute an Event of Default exists or
has occurred and is continuing (i) demand payment on Accounts or other proceeds

name on any proof of claim in bankruptcy or other similar document against an
account debtor, (viii) notify the post office authorities to change the address

open and dispose of all mail addressed to any Borrower, and (ix) do all acts and
things which are necessary, in Lender's determination, to fulfill Borrowers'
obligations under this Agreement and the other Financing Agreements and (b) at
any time to (i) take control in any manner of any item of payment or proceeds
thereof, (ii) have access to any lockbox or postal box into which any Borrower's

                                                                              25

attorney and in furtherance thereof, whether of omission or commission, except
as a result of Lender's own gross negligence or willful misconduct as determined
pursuant to a final non-appealable order of a court of competent jurisdiction.

rights of Lender with respect thereto. Lender may add any amounts so expended to
the Obligations and charge Borrowers' account therefor, such amounts to be
repayable by Borrowers on demand. Lender shall be under no obligation to effect
such cure, payment or bonding and shall not, by doing so, be deemed to have
assumed any obligation or liability of Borrowers. Any payment made or other
action taken by Lender under this Section shall be without prejudice to any
right to assert an Event of Default hereunder and to proceed accordingly.

cost and expense of Borrowers, (a) Lender or its designee shall have complete
access to all of Borrowers' premises during normal business hours and after
notice to Borrowers, or at any time and without notice to Borrowers if an Event

8.  REPRESENTATIONS AND WARRANTIES

    Each Borrower hereby represents and warrants to Lender the following (which
shall survive the execution and delivery of this Agreement), the truth and
accuracy of which are a continuing condition of the making of Loans by Lender to
Borrowers:

     8.1 Corporate Existence, Power and Authority; Subsidiaries. Each Borrower
is a corporation duly organized and in good standing under the laws of its state
of incorporation and is duly qualified as a foreign corporation and in good
standing in all states or other jurisdictions where the nature and extent of the
business transacted by it or the ownership of assets makes such qualification
necessary, except for those jurisdictions in which the failure to so qualify
would not have a material adverse effect on any Borrower's financial condition,
results of operation or

                                                                              26
<PAGE>

business or the rights of Lender in or to any of the Collateral. The execution,
delivery and performance of this Agreement, the other Financing Agreements and
the transactions contemplated hereunder and thereunder are all within each
Borrower's corporate powers, have been duly authorized and are not in
contravention of law or the terms of any Borrower's certificate of
incorporation, by-laws, or other organizational documentation, or any indenture,
agreement or undertaking to which any Borrower is a party or by which any
Borrower or its property are bound. This Agreement and the other Financing
Agreements constitute legal, valid and binding obligations of each Borrower
enforceable in accordance with their respective terms. Borrowers do not have any
subsidiaries except as set forth on the Information Certificate.

     8.2 Financial Statements; No Material Adverse Change. All financial
statements relating to Borrowers which have been or may hereafter be delivered
by Borrowers to Lender have been prepared in accordance with GAAP and fairly
present the financial condition and the results of operation of Borrowers as at
the dates and for the periods set forth therein. Except as disclosed in any
interim financial statements furnished by Borrowers to Lender prior to the date
of this Agreement, there has been no material adverse change in the assets,
liabilities, properties and condition, financial or otherwise, of any Borrower,
since the date of the most recent audited financial statements furnished by
Borrowers to Lender prior to the date of this Agreement.

     8.3 Chief Executive Office; Collateral Locations. The chief executive
office of each Borrower and each Borrower's Records concerning Accounts are
located only at the addresses set forth below on the signature pages hereof and
their only other places of business and the only other locations of Collateral,
if any, are the addresses set forth in the Information Certificates, subject to
the right of Borrowers to establish new locations in accordance with Section 9.2
below. The Information Certificates correctly identify any of such locations
which are not owned by a Borrower and sets forth the owners and/or operators
thereof and to the best of Borrowers' knowledge, the holders of any mortgages on
such locations.

     8.4 Priority of Liens; Title to Properties. The security interests and
liens granted to Lender under this Agreement and the other Financing Agreements
constitute valid and perfected first priority liens and security interests in
and upon the Collateral subject only to the liens indicated on Schedule 8.4
hereto and the other liens permitted under Section 9.8 hereof. Each Borrower has
good and marketable title to all of its properties and assets subject to no
liens, mortgages, pledges, security interests, encumbrances or charges of any
kind, except those granted to Lender and such others as are specifically listed
on Schedule 8.4 hereto or permitted under Section 9.8 hereof.

     8.5 Tax Returns. Each Borrower has filed, or caused to be filed, in a
timely manner all tax returns, reports and declarations which are required to be
filed by it (without requests for extension except as previously disclosed in
writing to Lender). All information in such tax returns, reports and
declarations is complete and accurate in all material respects. Each Borrower
has paid or caused to be paid all taxes due and payable or claimed due and
payable in any assessment received by it, except taxes the validity of which are
being contested in good faith by appropriate proceedings diligently pursued and
available to Borrowers and with respect to which adequate reserves have been set
aside on its books. Adequate provision has been made for the

     actual, of any Hazardous Material or the generation, use, storage,
     treatment, transportation, manufacture, handling, production or disposal of
     any Hazardous Materials or any other environmental, health or safety

     are valid and in full force and effect.

     8.11 Interdependent Businesses and Operations. Each of the Borrowers
acknowledges and agrees that it acts interdependently with the other Borrowers
as part of a common business enterprise and relies upon the other Borrowers in
its operations and business. Each of the

                                                                              29
<PAGE>

Borrowers further acknowledges and agrees that the Loans made and to be made
hereunder by Lender would not be made except on the basis of the joint and
several liability of the Borrowers and that each Borrower has derived and will
derive substantial direct and indirect economic benefits from the Loans made and
to be made hereunder by Lender to the other Borrowers.

     8.12 Year 2000. Each Borrower has taken all necessary action to access and
evaluate all of the hardware, software, embedded microchips and other processing
capabilities it uses and which is used in the products it sells, directly or
indirectly, and has made inquiry of each Borrower's material suppliers and
vendors, to be able to ensure that each Borrower and each product it sells will
be able to function accurately and without interruption using date information
before, during and after January 1, 2000. Any reprogramming of any computer
systems or equipment required to permit the proper functioning of the Borrowers
and their business and each product they sell following January 1, 2000 and any
testing of such systems and equipment and each product they sell will be

mature and has (and has reason to believe it will continue to have) sufficient
capital (and not unreasonably small capital) to carry on its business and all
businesses in which it is about to engage. The assets and properties of each
Borrower at a fair valuation and at their present fair salable value are, and
will be, greater than the liabilities and indebtedness of each such Borrower,
and including subordinated and contingent liabilities computed at the amount
which, to the best of Borrowers' knowledge, represents an amount which can
reasonably be expected to become an actual or matured liability.

     8.14 Accuracy and Completeness of Information. All information furnished by
or on behalf of Borrowers in writing to Lender in connection with this Agreement
or any of the other Financing Agreements or any transaction contemplated hereby
or thereby, including all information on the Information Certificates is true
and correct in all material respects on the date as of which such information is
dated or certified and does not omit any material fact necessary in order to
make such information not misleading. No event or circumstance has occurred
which has had or could reasonably be expected to have a material adverse affect
on the business, assets or prospects of any Borrower, which has not been fully
and accurately disclosed to Lender in writing.

contained in this Agreement or any of the other Financing Agreements shall
survive the execution and delivery of this Agreement and shall be deemed to have
been made again to Lender on the date of each additional borrowing or other
credit accommodation hereunder and shall be conclusively presumed to have been
relied on by Lender regardless of any investigation made or information
possessed by Lender. The representations and warranties set forth herein shall
be cumulative and in addition to any other representations or warranties which
Borrowers shall now or hereafter give, or cause to be given, to Lender.

                                                                              30

     Lender's request and Borrowers' expense: (i) cause an independent
     environmental engineer acceptable to Lender to conduct such tests of the
     site where Borrowers' non-compliance or alleged non-compliance with such

     deliver to Lender a report as to such non-compliance setting forth the
     results of such tests, a proposed plan for responding to any environmental
     problems described therein, and an estimate of the costs thereof and (ii)
     provide to Lender a supplemental report of such engineer whenever the scope
     of such non-compliance, or Borrowers' response thereto or the estimated
     costs thereof, shall change in any material respect.

          (e) Borrowers shall indemnify, defend and hold harmless Lender, its

     Material, including the costs of any required or necessary repair, cleanup
     or other remedial work with respect to any property of Borrowers and the
     preparation and implementation of any closure, remedial or other required

on Lender as a result of the financing arrangements provided for herein and each
Borrower agrees to indemnify, defend and hold Lender harmless with respect to
the foregoing, and to repay to Lender on demand the amount thereof, and until

such insurance at the expense of Borrowers. All policies shall provide for at
least thirty (30) days prior written notice to Lender of any cancellation or
reduction of coverage and that Lender may act as attorney for Borrowers in

policies and Borrowers shall obtain non-contributory lender's loss payable
endorsements to all insurance policies in form and substance satisfactory to
Lender. Such lender's loss payable endorsements shall specify that the proceeds
of such insurance shall be payable to Lender as its interests may appear and
further specify that Lender shall be paid regardless of any act or omission by
Borrowers or any of its affiliates. At its option, Lender may apply any
insurance proceeds received by Lender at any time to the cost of repairs or
replacement of Collateral and/or to payment of the Obligations, whether or not
then due, in any order and in such manner as Lender may determine or hold such
proceeds as cash collateral for the Obligations.

     reportable event or any other event or condition which presents a material

          (b) As used in this Section 9.17, the terms "employee benefit plans",

     respective meanings assigned to them in ERISA, and the term "prohibited
     transaction" shall have the meaning assigned to it in Section 4975 of the
     Code and ERISA.

     9.18 Further Assurances. At the request of Lender at any time and from time
to time, each Borrower shall, at its expense, duly execute and deliver, or cause
to be duly executed and delivered, such further agreements, documents and
instruments, and do or cause to be done such further acts as may be necessary or
proper to evidence, perfect, maintain and enforce the security interests and the
priority thereof in the Collateral and to otherwise effectuate the provisions or
purposes of this Agreement or any of the other Financing Agreements. Lender may
at any time and from time to time request a certificate from an officer of
Borrowers representing that all conditions precedent to the making of Loans
contained herein are satisfied. In the event of such request by Lender, Lender
may, at its option, cease to make any further Loans until Lender has received
such certificate and, in addition, Lender has determined that such conditions
are satisfied. Where permitted by law, each Borrower hereby authorizes Lender to
execute and file one or more UCC financing statements signed only by Lender.

<PAGE>

     Financing Agreements.

     10.2 Remedies.

          (a) At any time an Event of Default exists or has occurred and is
     continuing, Lender shall have all rights and remedies provided in this
     Agreement, the other Financing Agreements, the Uniform Commercial Code and
     other applicable law, all of which rights and remedies may be exercised
     without notice to or consent by any Borrower or any Obligor, except as such
     notice or consent is expressly provided for hereunder or required by
     applicable law. All rights, remedies and powers granted to Lender
     hereunder, under any of the other Financing Agreements, the Uniform
     Commercial Code or other applicable law, are cumulative, not exclusive and
     enforceable, in Lender's discretion, alternatively, successively, or
     concurrently on any one or more occasions, and shall include, without
     limitation, the right to apply to a court of equity for an injunction to
     restrain a breach or threatened breach by any Borrower of this Agreement or
     any of the other Financing Agreements. Lender may, at any time or times,
     proceed directly against any Borrower or any Obligor to collect the
     Obligations without prior recourse to the Collateral.

          (b) Without limiting the foregoing, at any time an Event of Default
     exists or has occurred and is continuing, Lender may, in its discretion and
     without limitation, (i) accelerate the payment of all Obligations and
     demand immediate payment thereof to Lender (provided, that, upon the
     occurrence of any Event of Default described in Sections 10.1(g) and
     10.1(h), all Obligations shall automatically become immediately due and
     payable), (ii) with or without judicial process or the aid or assistance of
     others, enter upon any premises on or in which any of the Collateral may be
     located and take possession of the Collateral or complete processing,
     manufacturing and repair of all or any portion of the Collateral, (iii)
     require each Borrower, at Borrowers' expense, to assemble and make
     available to Lender any part or all of the Collateral at any place and time
     designated by Lender, (iv) collect, foreclose, receive, appropriate, setoff
     and realize upon any and all Collateral, (v) remove any or all of the
     Collateral from any premises on or in which the same may be located for the
     purpose of effecting the sale, foreclosure or other disposition thereof or
     for any other purpose, (vi) sell, lease, transfer, assign, deliver or
     otherwise dispose of any and all Collateral (including entering into
     contracts with respect thereto, public or private sales at any exchange,
     broker's board, at any office of Lender or elsewhere) at such prices or
     terms as Lender may deem commercially reasonable, for cash, upon credit or
     for future delivery, with the Lender having the right to purchase the whole
     or any part of the Collateral at any such public sale, all of the foregoing
     being free from any right or equity of redemption of each Borrower, which
     right or equity of redemption is hereby expressly waived and released by
     each

                                                                              40
<PAGE>

     Borrower and/or (vii) terminate this Agreement. If any of the Collateral is
     sold or leased by Lender upon credit terms or for future delivery, the
     Obligations shall not be reduced as a result thereof until payment therefor
     is finally collected by Lender. If notice of disposition of Collateral is
     required by law, five (5) days prior notice by Lender to Borrowers
     designating the time and place of any public sale or the time after which
     any private sale or other intended disposition of Collateral is to be made,
     shall be deemed to be reasonable notice thereof and each Borrower waives
     any other notice. In the event Lender institutes an action to recover any
     Collateral or seeks recovery of any Collateral by way of prejudgment
     remedy, each Borrower waives the posting of any bond which might otherwise
     be required.

          (c) Lender may apply the cash proceeds of Collateral actually received
     by Lender from any sale, lease, foreclosure or other disposition of the
     Collateral to payment of the Obligations, in whole or in part and in such
     order as Lender may elect, whether or not then due. Each Borrower shall
     remain liable to Lender for the payment of any deficiency with interest at
     the highest rate provided for herein and all costs and expenses of
     collection or enforcement, including attorneys' fees and legal expenses.

          (d) Without limiting the foregoing, upon the occurrence of an Event of
     Default or an event which with notice or passage of time or both would
     constitute an Event of Default, Lender may, at its option, without notice,
     (i) cease making Loans or reduce the lending formulas or amounts of
     Revolving Loans available to Borrower and/or (ii) terminate any provision
     of this Agreement providing for any future Loans to be made by Lender to
     Borrower.

          (e) Each Borrower acknowledges and agrees that each and every Event of
     Default described above shall be of equal weight and significance, and
     equally and fully shall allow Lender to exercise its rights and remedies
     hereunder. Each Borrower acknowledges and agrees that each such Event of
     Default has been a material inducement for Lender to enter into this
     Agreement and that Lender would be irreparably harmed if Lender, in any
     way, were unable to exercise its rights and remedies on the basis that
     certain Events of Default (for example, Events of Default not relating to
     payment) were of less weight or significance than certain other Events of
     Default (for example, Events of Default relating to payment).

11. JURY TRIAL WAIVER; OTHER WAIVERS AND CONSENTS; GOVERNING LAW

    11.1  Governing Law; Choice of Forum; Service of Process; Jury Trial Waiver.

          (a) The validity, interpretation and enforcement of this Agreement and
     the other Financing Agreements and any dispute arising out of the
     relationship between the parties hereto, whether in contract, tort, equity
     or otherwise, shall be governed by the internal laws of the Commonwealth of
     Massachusetts (without giving effect to principles of conflicts of law).

          (b) Each Borrower and Lender irrevocably consent and submit to the
     non-exclusive jurisdiction of the Superior Court of Suffolk County of the
     Commonwealth of Massachusetts and the United States District Court for the
     District of Massachusetts and waive any objection based on venue or forum
     non conveniens with respect to any action instituted therein arising under
     this Agreement or any of the other Financing Agreements or in any way

                                                                              41
<PAGE>

     connected with or related or incidental to the dealings of the parties
     hereto in respect of this Agreement or any of the other Financing
     Agreements or the transactions related hereto or thereto, in each case
     whether now existing or hereafter arising, and whether in contract, tort,
     equity or otherwise, and agree that any dispute with respect to any such
     matters shall be heard only in the courts described above (except that
     Lender shall have the right to bring any action or proceeding against each
     and every Borrower or its property in the courts of any other jurisdiction
     which Lender deems necessary or appropriate in order to realize on the
     Collateral or to otherwise enforce its rights against Borrowers or their
     property).

          (c) Each Borrower hereby waives personal service of any and all
     process upon it and consents that all such service of process may be made
     by certified mail (return receipt requested) directed to its address set
     forth on the signature pages hereof and service so made shall be deemed to
     be completed five (5) days after the same shall have been so deposited in
     the U.S. mails, or, at Lender's option, by service upon each and every
     Borrower in any other manner provided under the rules of any such courts.
     Within thirty (30) days after such service, each Borrower shall appear in
     answer to such process, failing which Borrowers shall be deemed in default
     and judgment may be entered by Lender against Borrowers for the amount of
     the claim and other relief requested.

          (d) EACH BORROWER AND LENDER EACH HEREBY WAIVES ANY RIGHT TO TRIAL BY
     JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS
     AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR (ii) IN ANY WAY
     CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES
     HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE OTHER FINANCING
     AGREEMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE
     WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT,
     EQUITY OR OTHERWISE. EACH BORROWER AND LENDER HEREBY AGREES AND CONSENTS
     THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY
     COURT TRIAL WITHOUT A JURY AND THAT EACH BORROWER OR LENDER MAY FILE AN
     ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN
     EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT
     TO TRIAL BY JURY.

          (e) Lender shall not have any liability to any Borrower (whether in
     tort, contract, equity or otherwise) for losses suffered by any Borrower in
     connection with, arising out of, or in any way related to the transactions
     or relationships contemplated by this Agreement, or any act, omission or
     event occurring in connection herewith, unless it is determined by a final
     and non-appealable judgment or court order binding on Lender, that the
     losses were the result of acts or omissions constituting gross negligence
     or willful misconduct. In any such litigation, Lender shall be entitled to
     the benefit of the rebuttable presumption that it acted in good faith.

     11.2 Waiver of Notices. Each Borrower hereby expressly waives demand,
presentment, protest and notice of protest and notice of dishonor with respect
to any and all instruments and commercial paper, included in or evidencing any
of the Obligations or the Collateral, and any and all other demands and notices
of any kind or nature whatsoever with respect to the Obligations,

                                                                              42
<PAGE>

the Collateral and this Agreement, except such as are expressly provided for
herein. No notice to or demand on any Borrower which Lender may elect to give
shall entitle Borrowers to any other or further notice or demand in the same,
similar or other circumstances.

     11.3 Amendments and Waivers. Neither this Agreement nor any provision
hereof shall be amended, modified, waived or discharged orally or by course of
conduct, but only by a written agreement signed by an authorized officer of
Lender, and as to amendments, as also signed by an authorized officer of
Borrowers. Lender shall not, by any act, delay, omission or otherwise be deemed
to have expressly or impliedly waived any of its rights, powers and/or remedies
unless such waiver shall be in writing and signed by an authorized officer of
Lender. Any such waiver shall be enforceable only to the extent specifically set
forth therein. A waiver by Lender of any right, power and/or remedy on any one
occasion shall not be construed as a bar to or waiver of any such right, power
and/or remedy which Lender would otherwise have on any future occasion, whether
similar in kind or otherwise.

     11.4 Waiver of Counterclaims. Until such time as the Obligations are
indefeasibly paid in full in cash or immediately available funds, each Borrower
waives all rights to interpose any claims, deductions, setoffs or counterclaims
of any nature (other then compulsory counterclaims) in any action or proceeding
with respect to this Agreement, the Obligations, the Collateral or any matter
arising therefrom or relating hereto or thereto.

     11.5 Indemnification. Each Borrower shall indemnify, defend and hold
Lender, and its directors, agents, employees and counsel, harmless from and
against any and all losses, claims, damages, liabilities, costs or expenses
imposed on, incurred by or asserted against any of them in connection with any
litigation, investigation, claim or proceeding commenced or threatened related
to the negotiation, preparation, execution, delivery, enforcement, performance
or administration of this Agreement, any other Financing Agreements, or any
undertaking or proceeding related to any of the transactions contemplated hereby
or any act, omission, event or transaction related or attendant thereto,
including amounts paid in settlement, court costs, and the fees and expenses of
counsel, except to the extent that a court of competent jurisdiction determines
by a final and nonappealable order binding on Lender, that the losses, claims,
damages, liabilities, costs and expenses were the result of the Lender's acts or
omissions constituting gross negligence or willful misconduct. To the extent
that the undertaking to indemnify, pay and hold harmless set forth in this
Section may be unenforceable because it violates any law or public policy,
Borrowers shall pay the maximum portion which it is permitted to pay under
applicable law to Lender in satisfaction of indemnified matters under this
Section. The foregoing indemnity shall survive the payment of the Obligations
and the termination or non-renewal of this Agreement.

12.  TERM OF AGREEMENT; MISCELLANEOUS

12.1   Term.

          (a) This Agreement and the other Financing Agreements shall become
     effective as of the date set forth on the first page hereof and shall
     continue in full force and effect for a term ending on the date five (5)
     years from the date hereof (the "Renewal Date"), and from year to

                                                                              43
<PAGE>

     year thereafter, unless sooner terminated pursuant to the terms hereof.
     Lender or Borrowers may terminate this Agreement and the other Financing
     Agreements effective on the Renewal Date or on the anniversary of the
     Renewal Date in any year by giving to the other party at least sixty (60)
     days prior written notice; provided, that, this Agreement and all other
     Financing Agreements must be terminated simultaneously. Upon the effective
     date of termination or non-renewal of the Financing Agreements, Borrowers
     shall pay to Lender, in full, all outstanding and unpaid Obligations and
     shall furnish cash collateral to Lender in such amounts as Lender
     determines are reasonably necessary to secure Lender from loss, cost,
     damage or expense, including attorneys' fees and legal expenses, in
     connection with any contingent Obligations, including checks or other
     payments provisionally credited to the Obligations and/or as to which
     Lender has not yet received final and indefeasible payment. Such payments
     in respect of the Obligations and cash collateral shall be remitted by wire
     transfer in Federal funds to such bank account of Lender, as Lender may, in
     its discretion, designate in writing to Borrowers for such purpose.
     Interest shall be due until and including the next business day, if the
     amounts so paid by Borrowers to the bank account designated by Lender are
     received in such bank account later than 12:00 noon, Boston, Massachusetts
     time. Upon the indefeasible payment in full of all of the Obligations in
     cash or immediately available funds and the provision of cash collateral as
     provided above, the Lender shall, at Borrowers' expense, release its
     security interests and liens in the Collateral.

          (b) No termination of this Agreement or the other Financing Agreements
     shall relieve or discharge any Borrower of its respective duties,
     obligations and covenants under this Agreement or the other Financing
     Agreements until all Obligations have been fully and finally discharged and
     paid, and Lender's continuing security interest in the Collateral and the
     rights and remedies of Lender hereunder, under the other Financing
     Agreements and applicable law, shall remain in effect until all such
     Obligations have been fully and finally discharged and paid.

          (c) If for any reason this Agreement is terminated prior to the end of
     the then current term or renewal term of this Agreement, in view of the
     impracticality and extreme difficulty of ascertaining actual damages and by
     mutual agreement of the parties as to a reasonable calculation of Lender's
     lost profits as a result thereof and as a result of Lender's deferral of
     payment of fees that would be payable at the inception and during the term
     of this Agreement, Borrowers agree to pay to Lender, upon the effective
     date of such termination, an early termination fee in the amount set forth
     below if such termination is effective in the period indicated:

                   Amount                             Period
              -----------------      -----------------------------------------
(i)             3% of Maximum        From the date hereof to and including
                   Credit            the first anniversary of the date hereof;

(ii)            2% of Maximum        From the day after the first anniversary
                   Credit            of the date hereof to and including the
                                     second anniversary of the date hereof;
                                     and

(iii)           1% of Maximum        From the day after the second
                   Credit            anniversary of the date hereof to and
                                     including the fifth anniversary of the
                                     date hereof.

                                                                              44
<PAGE>

Such early termination fee shall be presumed to be the amount of damages
sustained by Lender as a result of such early termination and Borrowers agree
that it is reasonable under the circumstances currently existing.  In addition,
Lender shall be entitled to such early termination fee upon the occurrence of
any Event of Default described in Sections 10.1(g) and 10.1(h) hereof, even if
Lender does not exercise its right to terminate this Agreement, but elects, at
its option, to provide financing to Borrowers or permit the use of cash
collateral under the United States Bankruptcy Code.  The early termination fee
provided for in this Section 12.1 shall be deemed included in the Obligations.

     12.2 Notices. All notices, requests and demands hereunder shall be in
writing and (a) made to Lender at its address set forth below and to Borrowers
at their respective chief executive offices set forth below, or to such other
address as either party may designate by written notice to the other in
accordance with this provision, and (b) deemed to have been given or made: if
delivered in person, immediately upon delivery; if by telex, telegram or
facsimile transmission, immediately upon sending and upon confirmation of
receipt; if by nationally recognized overnight courier service with instructions
to deliver the next business day, one (1) business day after sending; and if by
certified mail, return receipt requested, five (5) days after mailing.

     12.3 Partial Invalidity. If any provision of this Agreement is held to be
invalid or unenforceable, such invalidity or unenforceability shall not
invalidate this Agreement as a whole, but this Agreement shall be construed as
though it did not contain the particular provision held to be invalid or
unenforceable and the rights and obligations of the parties shall be construed
and enforced only to such extent as shall be permitted by applicable law.

     12.4 Successors. This Agreement, the other Financing Agreements and any
other document referred to herein or therein shall be binding upon and inure to
the benefit of and be enforceable by Lender, Borrowers and their respective
successors and assigns, except that Borrowers may not assign their rights under
this Agreement, the other Financing Agreements and any other document referred
to herein or therein without the prior written consent of Lender. Lender may,
after notice to Borrowers, assign its rights and delegate its obligations under
this Agreement and the other Financing Agreements and further may assign, or
sell participations in, all or any part of the Loans, or any other interest
herein to another financial institution or other person, in which event, the
assignee or participant shall have, to the extent of such assignment or
participation, the same rights and benefits as it would have if it were the
Lender hereunder, except as otherwise provided by the terms of such assignment
or participation.

     12.5 Joint and Several Liability. All Loans made hereunder are made to or
for the benefit of each of the Borrowers. The Borrowers are jointly and
severally, directly and primarily, absolutely and unconditionally liable for the
full and indefeasible payment when due and performance of all Obligations and
for the prompt and full payment and performance of all of the promises,
covenants, representations, and warranties made or undertaken by each Borrower
under

                                                                              45
<PAGE>

the Financing Agreements and Borrowers agree that such liability is independent
of the duties, obligations, and liabilities of each of the joint and several
Borrowers.

     12.6 Suretyship Waivers and Consents.

          (a) Each Borrower acknowledges and agrees that the Obligations
     undertaken herein are direct and primary obligations and that each such
     Borrower is jointly and severally obligated thereon with the other
     Borrowers. In full recognition thereof, each Borrower consents and agrees
     that Lender may, at any time and from time to time, without notice or
     demand, (except as provided in and in accordance with the terms of this
     Agreement), whether before or after any actual or purported termination,
     repudiation or revocation of this Agreement by any Borrower, and without
     affecting the enforceability or continuing effectiveness hereof as to each
     Borrower: (i) increase, extend, or otherwise change the time for payment or
     the terms of the Obligations or any part thereof; (ii) supplement, restate,
     modify, amend, increase, decrease, or waive, or enter into or give any
     agreement, approval or consent with respect to, the Obligations or any part
     thereof, or any of the Financing Agreements or any additional security or
     guarantees, or any condition, covenant, default, remedy, right,
     representation, or term thereof or thereunder; (iii) accept new or
     additional instruments, documents, or agreements in exchange for or
     relative to any of the Financing Agreements or the Obligations or any part
     thereof; (iv) accept partial payments on the Obligations; (v) receive and
     hold additional security or guarantees for the Obligations or any part
     thereof; (vi) release, reconvey, terminate, waive, abandon, fail to
     perfect, subordinate, exchange, substitute, transfer, or enforce any
     Collateral, security or guarantees, and apply any Collateral or security
     and direct the order or manner of sale thereof as Lender in its sole and
     absolute discretion may determine; (vii) release any person from any
     personal liability with respect to the Obligations or any part thereof;
     (viii) settle, release on terms satisfactory to Lender or by operation of
     applicable laws or otherwise liquidate or enforce any Obligations and any
     Collateral or security therefor or guaranty thereof in any manner, consent
     to the transfer of any Collateral or security and bid and purchase at any
     sale; or (ix) consent to the merger, change, or any other restructuring or
     termination of the corporate or partnership existence of any Borrower, and
     any corresponding restructuring of the Obligations, and any such merger,
     change, restructuring, or termination shall not affect the liability of any
     Borrower or the continuing effectiveness hereof, or the enforceability
     hereof with respect to all or any part of the Obligations.

          (b) Lender may enforce this Agreement independently as to each
     Borrower and independently of any other remedy or security Lender at any
     time may have or hold in connection with the Obligations, and it shall not
     be necessary for Lender to marshal assets in favor of any Borrower or any
     Obligor or to proceed upon or against or exhaust any Collateral or security
     or remedy before proceeding to enforce this Agreement. Each Borrower
     expressly waives any right to require Lender to marshal assets in favor of
     any Borrower or any guarantor of the Obligations or to proceed against any
     other Borrower, and agrees that Lender may proceed against Borrowers or any
     Collateral in such order as Lender shall determine in its sole an absolute
     discretion.

          (c) Lender may file a separate action or actions against any Borrower,
     whether such action is brought or prosecuted with respect to any security
     or against any guarantor of the Obligations, or whether any other person is
     joined in any such action or actions. Each Borrower

                                                                              46
<PAGE>

     agrees that Lender and each Borrower and any affiliate of any Borrower may
     deal with each other in connection with the Obligations or otherwise, or
     alter any contracts or agreements now or hereafter existing between any of
     them, in any manner whatsoever, all without in any way altering or
     affecting the continuing enforceability of this Agreement. Each Borrower,
     as a joint and several Borrower hereunder, expressly waives the benefit of
     any statute of limitations affecting its joint and several liability
     hereunder (but not its primary liability) or the enforcement of the
     Obligations or any rights of Lender created or granted herein.

          (d) Lender's rights hereunder shall be reinstated and revived, and the
     enforceability of this Agreement shall continue, with respect to any amount
     at any time paid on account of the Obligations which thereafter shall be
     required to be restored or returned by Lender, all as though such amount
     had not been paid. The rights of Lender created or granted herein and the
     enforceability of this Agreement at all times shall remain effective to
     cover the full amount of all the Obligations even though the Obligations,
     including any part thereof or any Collateral, other security or guaranty
     therefor, may be or hereafter may become invalid or otherwise unenforceable
     as against any Borrower and whether or not any Borrower shall have any
     personal liability with respect thereto.

          (e) Each Borrower expressly waives any and all defenses now or
     hereafter arising or asserted by reason of (i) any disability or other
     defense of any other Borrower with respect to the Obligations; (ii) the
     unenforceability or invalidity of any security or guaranty for the
     Obligations or the lack of perfection or continuing perfection or failure
     of priority of any security for the Obligations; (iii) the cessation for
     any cause whatsoever of the liability of any other Borrower (other than by
     reason of the full payment and performance of all Obligations); (iv) any
     failure of Lender to marshal assets in favor of any Borrower; (v) any act
     or omission of Lender or others that directly or indirectly results in or
     aids the discharge or release of any Borrower or the Obligations of any
     Borrower or any security or guaranty therefor by operation of law or
     otherwise; (vi) any law which provides that the obligation of a surety or
     guarantor must neither be larger in amount nor in other respects more
     burdensome than that of the principal or which reduces a surety's or
     guarantor's obligation in proportion to the principal obligation; (vii) any
     failure of Lender to file or enforce a claim in any bankruptcy or other
     proceeding with respect to any Borrower; (viii) the avoidance of any lien
     or security interest in assets of any Borrower in favor of Lender for any
     reason; or (ix) any action taken by Lender that is authorized by this
     section or any other provision of any Financing Agreements. Until such
     time, if any, as all of the Obligations have been indefeasibly paid and
     performed in full and no portion of any commitment of Lender to Borrowers
     under any Financing Agreement remains in effect, each Borrower's
     indebtedness, claims and rights of subrogation, contribution,
     reimbursement, or indemnity against the other Borrowers shall be fully and
     completely subordinated to the indefeasible repayment in full of the
     Obligations, and each Borrower expressly waives until such indefeasible
     payment any right to enforce any remedy that it now has or hereafter may
     have against any other Person and waives the benefit of, or any right to
     participate in, any Collateral now or hereafter held by Lender.

          (f) To the fullest extent permitted by applicable law, each Borrower
     expressly waives and agrees not to assert, any and all defenses in its
     favor based upon an election of remedies by Lender which destroys,
     diminishes, or affects such Borrower's subrogation rights

                                                                              47
<PAGE>

     against the other Borrowers, or against any other Obligor, and/or (except
     as explicitly provided for herein) any rights to proceed against each other
     Borrower, or any other party liable to Lender, for reimbursement,
     contribution, indemnity, or otherwise.

          (g) Borrowers and each of them warrant and agree that each of the
     waivers and consents set forth herein are made after consultation with
     legal counsel and with full knowledge of their significance and
     consequences, with the understanding that events giving rise to any defense
     or right waived may diminish, destroy, or otherwise adversely affect rights
     which Borrowers otherwise may have against each other, Lender, or others,
     or against Collateral, and that, under the circumstances, the waivers and
     consents herein given are reasonable and not contrary to public policy or
     law. If any of the waivers or consents herein are determined to be contrary
     to any applicable law or public policy, such waivers and consents shall be
     effective to the maximum extent permitted by law.

     12.7 Contribution Agreement. As an inducement to Lender to enter into the
Financing Agreements and to make the loans and extend credit to the Borrowers,
each Borrower agrees to indemnify and hold the other harmless from and each
shall have a continuing right of contribution against the other Borrowers, if
and to the extent that a Borrower makes or is caused to make disproportionate
payments in excess of that Borrower's Proportionate Share (as defined herein) of
the Loans or contributions (from dispositions of its assets or otherwise) to the
repayment and satisfaction of the Obligations. These indemnification and
contribution obligations shall be unconditional and continuing obligations of
the Borrowers and shall not be waived, rescinded, modified, limited or
terminated in any way whatsoever without the prior written consent of Lender, in
its sole discretion. These indemnification and contribution obligations are
subordinated to the prior indefeasible payment in full in cash of all
Obligations. For purposes hereof, Proportionate Share shall mean the amount of
Loans made in respect of a Borrower based upon the lending formulas and other
provisions of Section 2 hereof as shown on the loan account(s) and records
maintained by the Lender.

     12.8 Entire Agreement. This Agreement, the other Financing Agreements, any
supplements hereto or thereto, and any instruments or documents delivered or to
be delivered in connection herewith or therewith represents the entire agreement
and understanding concerning the subject matter hereof and thereof between the
parties hereto, and supersede all other prior agreements, understandings,
negotiations and discussions, representations, warranties, commitments,
proposals, offers and contracts concerning the subject matter hereof, whether
oral or written. In the event of any inconsistency between the terms of this
Agreement and any schedule or exhibit hereto, the terms of this Agreement shall
govern.

                                                                              48
<PAGE>

     IN WITNESS WHEREOF, Lender and Borrowers have caused these presents to be
duly executed as of the day and year first above written.
