Agreement, Lender agrees to make available for Borrower's use from time to 
time during the term of this Agreement, upon Borrower's request therefor, 
certain loans and other financial accommodations (the "Total Facility") 
consisting of the Revolving Loan and the Term Loan, as set forth more fully 
in Sections 2.2 and 2.3, respectively.

     2.2.  REVOLVING LOAN.

          A.  The Total Facility shall include a revolving line of credit 
consisting of advances against Eligible Accounts, Eligible Installment 
Accounts and Eligible Inventory (the "Revolving Loan") evidenced by an 
Amended and Restated Revolving Note, in the form attached hereto as Exhibit 
2.2(A), in an aggregate principal amount not to exceed, at any time 
outstanding, the lesser of (i) Eighteen Million Dollars ($18,000,000) or (ii)

at any particular time and from time to time, be equal to the sum of (a) 
eighty five (85%) (or such lesser percentage as the Lender may, at any time 
and from time to time, determined in the exercise of its reasonable credit 
judgment) of Eligible Accounts as determined by Lender plus (b) seventy 
percent (70%) (or such lesser percentage as the Lender may, at any time and 
from time to time, determined in the exercise of its reasonable credit 
judgment) of Eligible Installment Accounts as determined by Lender plus (c) 
sixty percent (60%) (or such lesser percentage as Lender may at any time and 
from time to time, determine in the exercise of its reasonable credit 
judgment) of Eligible Inventory. Notwithstanding the foregoing, the following 
limitations shall apply: (1) the aggregate amount of advances against 
Eligible Installment Accounts shall not exceed, at any time, the lesser of 
(x) Nine Million Dollars

                                       10


($9,000,000) or (y) fifty percent (50%) of the Maximum Amount of the 
Revolving Loan then in effect; and (2) the aggregate amount of advances 
against Eligible Inventory shall not exceed, at any time, the lesser of (x) 
One Million Five Hundred Thousand Dollars ($1,500,000) or (y) fifteen percent 
(15%) of the Maximum Amount of the Revolving Loan then in effect.

     In the event Lender decreases the advance percentages to be applied to 
Eligible Accounts, Eligible Installment Accounts and Eligible Inventory which 
are contained in this Section 2.2, such decrease shall become effective 
immediately for the purpose of calculating the amount which Lender agrees to 
advance, or allow to remain outstanding, against Eligible Accounts, Eligible 
Installment Accounts and Eligible Inventory.

          B.  Subject to the provisions of Section 2.2(A), in addition to the 
foregoing, Lender shall make available to Borrower an over advance facility 
(the "Over Advance Facility") in an amount not to exceed One Million Two 
Hundred Fifty Thousand Dollars ($1,250,000), provided that there shall be no 
outstanding Indebtedness under the Over Advance Facility for a period of not 
less than thirty (30) consecutive days during each Contract Year.

     2.3.  TERM LOAN.

conditions precedent set forth in Section 12.3 herein, Lender shall make a 
secured term loan (the "Term Loan") to Borrower in the principal amount equal 
to Three Million Dollars ($3,000,000). The Term Loan shall be evidenced by a 
promissory note to be executed and delivered by Borrower to Lender on the 
Closing Date, the form of which is attached hereto and made a part hereof as 
Exhibit 2.3 (the "Term Note"), shall bear interest as specified in Section 
2.5(B) and shall be paid in accordance with the terms of the Term Note. The 
Term Loan shall be funded on the Closing Date, which shall be no later than 
June 30, 1997. In the event that the Term Loan shall not have been funded in 
full on or before June 30, 1997, Lender's obligation to fund the Term Loan 
shall be permanently eliminated. The proceeds of the Term Loan shall be used 
by Borrower solely for the purposes enumerated in Section 2.12 herein. The 
Term Loan shall be a part of the Total Facility. Lender acknowledges that 
Borrower's failure to fulfill any condition precedent to the funding of the 
Term Loan or Borrower's election to forego having Lender fund the Term Loan 
shall not constitute a Default hereunder.

     2.4.  ADVANCES TO CONSTITUTE ONE REVOLVING LOAN.  All loans and advances 
by Lender to Borrower under this Agreement and the Ancillary Agreements 
(whether made as a Revolving Loan, a Term Loan or otherwise), shall 
constitute one loan and all indebtedness and obligations of Borrower to 
Lender under this Agreement and the Ancillary Agreements shall constitute one 
general obligation secured by the Collateral.

                                       11


   2.5. INTEREST RATE.

      (A) Revolving Loan.
               
         (i)   (a)  So long as no Event of Default has occurred and is 
continuing, Borrower shall pay to Lender interest on the Revolving Loan as 
follows: (x) Borrower shall pay interest on the principal balance of the 
amount outstanding under the Over Advance Facility equal to two hundred (200) 
basis points in excess of the Prime Rate; and (y) Borrower shall pay interest 
at the applicable Designated Rate on the outstanding principal balance of the 
Revolving Loan; provided, however, that upon the occurrence and during the 
continuation of an Event of Default, Lender may, at its option, raise the 
interest rate charges on the Liabilities to the Default Rate with respect to 
the Liabilities from the date of the occurrence of the Default until the 
earlier of (1) the Default is cured or waived by Lender or (2) the 
Liabilities are paid in full. Notwithstanding the provisions of the previous 
sentences, Borrower shall receive a ten (10) day period (commencing on the 
date of the occurrence of such application of the Default) to cure any 
non-monetary Default before Lender shall have the right to raise the interest 
rate charged on the Liabilities to the Default Rate. The applicable basis for 
determining the rate of interest with respect to the Revolving Loan shall be 
selected by Borrower initially at the time a request for an advance is given 
pursuant to Section 12.2(B)(vii). The basis for determining the interest rate 
with respect to the Revolving Loan may be changed from time to time by 
Borrower pursuant to Section 2.5(A)(v).

               (b)  Interest on the Revolving Loan shall be computed by 
multiplying the closing daily balance of the Revolving Loan as reflected in 
Borrower's Revolving Loan Account for each day during the preceding month by 
the interest rate determined to be applicable hereunder on each such day.

               (c)  Interest and all fees hereunder (other than prepayment 
fees) shall be computed on the basis of a 360-day year for the actual number 
of days elapsed. In computing interest on the Revolving Loan, the date of 
funding of the Revolving Loan or the first day of an Interest Period 
applicable to such Revolving Loan if it is a LIBOR Rate Revolving Loan, or 
with respect to a Base Rate Revolving Loan being converted from LIBOR Rate 
Revolving Loan, the date of conversion of such LIBOR Rate Revolving Loan to 
such Base Rate Revolving Loan, shall be included and the date of payment of 
such Revolving Loan or the expiration date of an Interest Period applicable 
to such Revolving Loan if it is a LIBOR Rate Revolving Loan, or with respect 
to a Base Rate Revolving Loan being converted to a LIBOR Rate Revolving Loan, 
the date of conversion of such Base Rate Revolving Loan to such LIBOR Rate 
Revolving Loan, shall be excluded; provided, that if a Revolving Loan is 
repaid on the same day on which it is made, one day's interest shall be paid 
on that Revolving Loan.

            (ii)  Following the occurrence of an Event of Default, Borrower 
shall pay to Lender interest from the date of the Default to and including the 
date of cure of such Default on the outstanding principal balance of the 
Liabilities at the Default Rate applicable to such Liabilities; provided, 
however, that in the case of LIBOR Rate Revolving Loan, upon the expiration 
of the Interest Period in effect at the time any Default shall have occurred 
and be 

                                      12



continuing, such LIBOR Rate Revolving Loan shall become Base Rate Revolving 
Loan and thereafter bear interest at the Default Rate applicable to Base Rate 
Revolving Loan.
                    
            (iii)   (a)  Interest shall be due at the Designated Rate as 
provided herein, after as well as before demand, default and judgment, 
notwithstanding any judgment rate of interest provided for in any statute. 
If any interest payment or other charge or fee payable hereunder exceeds the 
maximum amount then permitted by applicable law, then to the extent permitted 
by law and subject to the provisions of subparagraph (b) below, Borrower 
shall be obligated to pay the maximum amount then permitted by applicable law 
and Borrower shall continue to pay the maximum amount from time to time 
permitted by applicable law until all such interest payments and other charges 
and fees otherwise due hereunder (in the absence of such restraint imposed by 
applicable law) have been paid in full.

                    (b)  It is the intention of Lender and Borrower to comply 
with the laws of the State of Illinois, and notwithstanding any provision to 
the contrary contained herein or in the other Ancillary Agreements, Borrower 
shall not be required to pay and Lender shall not be permitted to collect any 
amount in excess of the maximum amount of interest permitted by law ("Excess 
Interest"). If any Excess Interest is provided for or determined to have been 
provided for by a court of competent jurisdiction in this Agreement or in any 
of the other Ancillary Agreements, then in such event: (a) the provisions of 
this subparagraph shall govern and control; (b) neither Borrower nor any 
guarantor or endorser shall be obligated to pay any Excess Interest; (c) any 
Excess Interest that Lender may have received hereunder shall be, at Lender's 
option (1) applied as a credit against the outstanding principal balance of 
the Liabilities or accrued and unpaid interest (not to exceed the maximum 
amount permitted by law), (2) refunded to the payor thereof, or (3) any 
combination of the foregoing; (d) the interest rate(s) provided for herein 
shall be automatically reduced to the maximum lawful rate allowed under 
applicable law, and this Agreement and the other Ancillary Agreements shall be 
deemed to have been, and shall be, reformed and modified to reflect such 
reduction; and (e) neither Borrower nor any guarantor or endorser shall have 
any action against Lender for any damages arising out of the payment or 
collection of any Excess Interest.

            (iv)  Subject to the provisions of Section 2.11(G), in connection 
with each LIBOR Rate Revolving Loan, Borrower shall elect an interest period 
(each an "Interest Period") to be applicable to such Revolving Loan, which 
Interest Period shall be either a 30, 60 or 90 period; PROVIDED, that:

                    (a) the initial Interest Period for any Revolving Loan 
shall commence on the date of funding of such Revolving Loan;

                    (b) in the case of immediately successive Interest 
Periods, each successive Interest Period shall commence on the day on which 
the immediately preceding Interest Period expires;

                    (c) if an Interest Period otherwise would expire on a day 
that is not a Business Day, such Interest Period shall expire on the next 
succeeding Business Day;

                                      13


provided, that if such next succeeding Business Day falls in a new calendar 
month, then such Interest Period shall expire on the immediately preceding 
Business Day;

                    (d) any Interest Period that begins on the last Business 
Day of a calendar month (or on a day for which there is no numerically 
corresponding day in the calendar month at the end of such Interest Period) 
shall, subject to paragraph (v) below, end on the last Business Day of a 
calendar month;

                    (e) no Interest Period shall extend beyond the last day 
of the Term;

                    (f) no Interest Period may extend beyond a date on which 
Borrower is required to make a required payment or prepayment of principal of 
the Revolving Loan (including prepayments pursuant to Section 2.8); and

                    (g) there shall be no more than two (2) Interest Periods 
relating to LIBOR Rate Revolving Loans outstanding at any time.

               (v) Subject to the provisions of Section 2.5(A)(iv) and 
Section 2.11(G), Borrower shall have the option to:

                    (a) convert at any time all or any part of any 
outstanding Base Rate Revolving Loan (except for loans pursuant to the Over 
Advance Facility which bear interest at the Prime Rate plus Two Hundred (200) 
basis points, and may not be converted to LIBOR Rate Loans) equal to Five 
Hundred Thousand Dollars ($500,000) and integral multiples of One Hundred 
Thousand Dollars ($100,000) in excess of that amount from a Base Rate 
Revolving Loan to a LIBOR Rate Revolving Loan or to convert a LIBOR Rate 
Revolving Loan in amounts equal to Five Hundred Thousand Dollars ($500,000) 
and integral multiples of One Hundred Thousand Dollars ($100,000) in excess 
of that amount from a LIBOR Rate Revolving Loan to a Base Rate Revolving 
Loan; or

                    (b) upon the expiration of any Interest Period applicable 
to a LIBOR Rate Revolving Loan, to continue all, or any portion of such 
Revolving Loan equal to any multiple of One Hundred Thousand Dollars 
($100,000) in excess of or below that amount (but in no event less than 
$500,000) as a LIBOR Rate Revolving Loan and the succeeding Interest 
Period(s) of such continued Revolving Loan shall commence on the last day of 
the Interest Period of the Revolving Loan to be continued; PROVIDED, that 
LIBOR Rate Revolving Loan may only be converted into Base Rate Revolving Loan 
on the expiration date of an Interest Period applicable thereto; PROVIDED, 
FURTHER, that no outstanding Revolving Loan may be continued as, or be 
converted into, a LIBOR Rate Revolving Loan when any Default with respect to 
the payment of money or any Event of Default has occurred and is continuing.

               (vi) Subject to the provisions of Sections 2.5(A)(v) and 
2.11(G):

                    (a) Borrower shall deliver a Notice of Conversion 
Continuation to Lender no later than 1:00 P.M. (Chicago, Illinois time) at 
least two (2) Business Days in


                                      14



advance of the proposed conversion/continuation date. A Notice of Conversion/ 
Continuation shall certify: (1) the proposed conversion/continuation date 
(which shall be a Business Day); (2) the amount of the Revolving Loan to be 
converted/continued; (3) the nature of the proposed conversion/continuation; 
(4) in the case of a conversion to, or a continuation of, a LIBOR Rate 
Revolving Loan, the requested Interest Period; and (5) in the case of a 
conversion to, or a continuation of, a LIBOR Rate Revolving Loan, that no 
Default or Event of Default has occurred and is continuing or would result 
from the proposed conversion/continuation. In lieu of delivering the 
above-described Notice of Conversion/Continuation, Borrower may give Lender 
telephonic notice by the required time of any proposed conversion/continuation 
under Section 2.5(A)(v); provided, that such notice shall be promptly 
confirmed in writing by delivery of a Notice of Conversion/Continuation to 
Lender on or before the proposed conversion/continuation date. If on any day 
a Revolving Loan is outstanding with respect to which notice has not been 
delivered to Lender in accordance with the terms of this Agreement specifying 
the basis for determining the rate of interest, then for that day that 
Revolving Loan shall be deemed to be a reference to the Base Rate.

                    (b) Lender shall not incur any liability to Borrower in 
acting upon any telephonic notice referred to above that Lender believes in 
good faith to have been given by or at the direction of an officer of 
Borrower or for otherwise acting in good faith under this Section 2.5(A)(vi) 
and, upon conversion/continuation by Lender in accordance with this 
Agreement pursuant to any telephonic notice, Borrower shall have effected 
such conversion or continuation, as the case may be, hereunder.

                    (c) A Notice of Conversion/Continuation for conversion to, 
or continuation of, a LIBOR Rate Revolving Loan (or telephonic notice in lieu 
thereof) shall be irrevocable once given, and Borrower shall be bound to 
convert or continue in accordance therewith.

               (vii) Subject to the additional provisions of Section 2.5(A), 
each LIBOR Rate Revolving Loan requested must equal at least Five Hundred 
Thousand Dollars ($500,000) and may only be in additional integral multiples 
of One Hundred Thousand Dollars ($100,000).

          (B) Term Loan.

               (i) Prior to the occurrence of an Event of Default or 
Maturity, all outstanding amounts due to Lender under the Term Loan shall 
bear interest at a fixed rate of fifteen percent (15%) per annum, payable 
monthly in arrears. Upon the occurrence of an Event of Default or Maturity, 
the interest rate then in effect for the Term Loan shall increase by two 
percent (2%).

               (ii) Interest and all fees hereunder (other than prepayment 
fees) shall be computed on the basis of a 360-day year for the actual number 
of days elapsed.

     2.6. METHOD OF BORROWING: METHOD OF MAKING INTEREST AND OTHER PAYMENTS. 
In its sole discretion, Lender may deem interest and other amounts payable 
hereunder (other than the principal balance of the Revolving Loan) to be paid 
by causing such amounts to be added to the


                                      15       


principal balance of the Revolving Loan, all as set forth on Lender's books 
and records. Unless otherwise directed by Lender, all payments to Lender 
hereunder shall be made by delivery thereof to Lender at its address set 
forth above or by delivery to Lender for deposit in the Depository Bank of 
all proceeds of Accounts or other Collateral in accordance with Section 4.3 
hereof. If Lender elects to bill Borrower for any amount due hereunder, such 
amount shall be immediately due and payable with interest thereon as provided 
herein. Solely for the purpose of calculating interest earned by Lender with 
respect to the Revolving Loan, any check, draft, wire transfer or similar 
item of payment by or for the account of Borrower delivered to Lender or 
deposited in the Depository Bank in accordance with Section 4.3 hereof shall 
be applied by Lender on account of Borrower's Revolving Loan obligations on 
the second Business Day after Lender has received immediately available funds 
as a result of the deposit thereof in accordance with Section 4.3 hereof. 
Immediately available funds received by Lender after 2:00 p.m. (Chicago, 
Illinois time) shall be deemed to have been received on the following 
Business Day.

     2.7.  TERM OF AGREEMENT. This Agreement shall be in effect from the 
Origination Date, through and including August 2, 1998 (the "Term"), 
provided, however, that Borrower and Lender agree that Lender's commitment to 
lend with respect to the Total Facility shall be automatically extended for 
an additional two (2) year period, commencing on August 2, 1998 and 
terminating on August 2, 2000 unless and until by the sixtieth (60th) day 
prior to the end of any Contract Year, Lender or Borrower shall have notified 
the other in writing of that party's intention to terminate the Total 
Facility effective on the last day of said Contract Year, subject to earlier 
termination by Lender upon the occurrence of a Default as provided in Section 
11.1. Upon the effective date of termination, all of the Liabilities shall 
become immediately due and payable without presentment, notice or demand, 
except as otherwise provided herein. Notwithstanding any termination, until 
all of the Liabilities shall have been fully paid and satisfied, Lender shall 
be entitled to retain its security interest in the Collateral, Borrower shall 
continue to remit collections of Accounts and proceeds of Collateral as 
provided in this Agreement, and Lender shall retain all of its rights and 
remedies under this Agreement.

     2.8.  PAYMENTS PRIOR TO END OF TERM.

          (A)  In consideration of Lender's allowance of the voluntary 
prepayment or termination of the Revolving Loan prior to the end of the Term, 
in addition to all other sums due Lender hereunder, Borrower shall pay to 
Lender a prepayment penalty equal to the lesser of Eighteen Million Dollars 
($18,000,000) or the amount of the Maximum Amount of the Revolving Loan in 
effect at the time of such voluntary prepayment TIMES (i) two percent (2%) if 
the voluntary prepayment and termination occurs in the first Contract Year; 
(ii) one percent (1%) if the voluntary prepayment occurs in the second 
Contract Year; or (iii) one-half percent (0.50%) of the voluntary prepayment 
occurs in the third Contract Year.

          (B)  Borrower may, at any time, pre-pay the Term Loan, in whole or 
in part, in amounts of at least Two Hundred Fifty Thousand Dollars 
($250,000). Such prepayments shall be applied to the scheduled installments 
of principal in the inverse order of maturity. In consideration of Lender's 
allowance of the voluntary prepayment or termination of the Term Loan prior 
to the end of the Term, in addition to all other sums due Lender hereunder, 
Borrower

                                       16



shall pay Lender a prepayment premium of (i) one and one-half percent (1.5%) 
of principal prepaid, if such prepayment is made within one (1) year of the 
Closing Date, and (ii) one percent (1%) of principal prepaid, if such 
prepayment is made thereafter. Notwithstanding the foregoing, the prepayment 
premium for voluntary prepayments of the Term Loan shall be waived by Lender 
if the proceeds for the prepayment are derived from the secondary offering of 
Borrower's Stock.

           (C)  Borrower shall make mandatory prepayments on the Term Loan in 
amounts equal to one hundred percent (100%) of the net cash proceeds received 
by Borrower from (i) the sale, transfer or other disposition of Borrower's 
fixed assets in excess of Fifty Thousand Dollars ($50,000) in any Fiscal 
Year, or (ii) the incurrence of any Permitted Subordinated Indebtedness 
subsequent to June 30, 1997. All such mandatory prepayments shall be applied 
to the scheduled installments of principal on the Term Loan in the inverse 
order of maturity. No mandatory prepayment shall be subject to a prepayment 
penalty or premium.

     2.9.   CLOSING FEES.  Borrower shall pay to Lender the following closing 
fees, which shall be deemed earned and which shall be payable in full on the 
date hereof:

           (A)  on account of the Revolving Loan, Fifty-Five Thousand Dollars 
($55,000); and

           (B)  on account of the Term Loan, Seventy-Five Thousand Dollars 
($75,000).

     2.10.  NON-USE FEE.  Borrower shall pay to Lender a Non-Use Fee equal to 
one-half of one percent (0.50%) per annum of the amount, if any, by which 
Eighteen Million Dollars ($18,000,000) has exceeded the average daily closing 
balance of the Revolving Loan during each calendar quarter or partial 
quarter during said period. The Non-Use Fee shall be payable in arrears on 
the first day of each calendar quarter and shall be calculated on the basis 
of a 360-day year for actual days elapsed.

     2.11.  SPECIAL PROVISIONS GOVERNING LIBOR RATE REVOLVING LOAN. 
Notwithstanding any other provision of this Agreement, the following 
provisions shall govern with respect to LIBOR Rate Revolving Loan as to the 
matters covered:

           (A) As soon a practicable after 1:00 p.m. (Chicago, Illinois time) 
on each Interest Rate Determination Date, Lender shall determine (which 
determination shall, absent manifest error, be final, conclusive and binding 
upon all parties) the interest rate that shall apply to the LIBOR Rate 
Revolving Loan for which an interest rate is then being determined for the 
applicable Interest Period and shall promptly give notice thereof (in 
writing or by telephone confirmed in writing) to Borrower.

           (B) If on any Interest Rate Determination Date Lender shall have 
determined (which determination shall be final and conclusive and binding 
upon Borrower) that:

               (i)  by reason of any changes arising after the date of this 
Agreement affecting the LIBOR market or affecting the position of Lender in 
such market, adequate and fair means do not exist for ascertaining the 
applicable interest rate by reference to the LIBOR Rate


                                      17




with respect to the LIBOR Rate Revolving Loan as to which an interest rate 
determination is then being made; or

              (ii)  by reasons of (a) any change after the date hereof in any 
applicable law or governmental rule, regulation or order (or any 
interpretation thereof and including the introduction of any new law or 
governmental rule, regulation or order) or (b) other circumstances affecting 
Lender or the LIBOR market or the position of Lender in such market (such as 
for example, but not limited to, official reserve requirements required by 
Regulation D to the extent not given effect in the Libor Rate), the LIBOR 
Rate shall not represent the effective pricing to Lender for dollar deposits 
of comparable amounts for the relevant period; then, and in any such event, 
Lender shall, promptly after being notified of a borrowing, conversion or 
continuation, give notice (by telephone confirmed in writing) to Borrower of 
such determination. Thereafter, Borrower shall pay to Lender, upon written 
demand therefor, such additional amounts (in the form of an increased rate 
of, or a different method of calculating, interest or otherwise as Lender in 
its reasonable credit judgment shall determine) as shall be required to cause 
Lender to receive interest with respect to the LIBOR Rate Revolving Loan for 
the Interest Period following that Interest Rate Determination Date at a 
rate per annum equal to two (2%) percent per annum in excess of the effective 
pricing to Lender for dollar deposits to make or maintain the LIBOR Rate 
Revolving Loan. A certificate as to additional amounts owed Lender, showing 
in reasonable detail the basis for the calculation thereof, submitted in good 
faith to Borrower shall, absent manifest error, be final and conclusive and 
binding upon Borrower.

     (C)  If on any date Lender shall have reasonably determined (which 
determination shall be final and conclusive and binding upon Borrower) that 
the making or continuation of any LIBOR Rate Revolving Loan has become 
unlawful or impossible by compliance by Lender in good faith with any law, 
governmental rule, regulation or order (whether or not having the force of law 
and whether or not failure to comply therewith would be unlawful), then, and 
in any such event, Lender shall promptly give notice (by telephone confirmed 
in writing) to Borrower of that determination. The obligation of Lender to 
make or maintain such LIBOR Rate Revolving Loan during any such period shall 
be terminated at the earlier of the termination of the Interest Period then 
in effect or when required by law and Borrower shall no later than the 
termination of the Interest Period in effect at the time any such 
determination pursuant to this Section is made or, earlier, when required by 
law, repay or prepay such LIBOR Rate Revolving Loan, together with all 
interest accrued thereon.

     (D)  Borrower shall compensate Lender, upon written request by Lender 
(which request shall set forth in reasonable detail the basis for requesting 
such amounts and which shall, absent manifest error, be conclusive and 
binding upon Borrower), for all reasonable losses, expenses and liabilities 
(including, without limitation, any loss (including interest paid) sustained 
by Lender in connection with the re-employment of such funds) Lender may 
sustain: (1) if for any reason (other than a default by Lender or the failure 
of a borrowing to occur due to the occurrence of any event described in 
Section 2.11(C)) a borrowing of any LIBOR Rate Revolving Loan does not occur 
on a date specified therefor in a request for an advance, a Notice of 
Conversion/Continuation or a telephonic request for borrowing or 
conversion/continuation or a successive Interest period does not commence 
after notice therefor is given pursuant to Section

                                      18



2.5(A)(vi); or (2) as consequence of any other default by Borrower to repay 
any LIBOR Rate Revolving Loan when required by the terms of this Agreement; 
provided, that during the period while any such amounts have not been paid, 
Lender shall reserve an equal amount from amounts otherwise available to be 
borrowed under the Revolving Loan. The provisions of this Section 2.11(D) 
shall survive the termination of this Agreement, the repayment of the 
Revolving Loan and the discharge of Borrower's other obligations hereunder.

           (E)  Lender may make, carry or transfer LIBOR Rate Revolving 
Loan at, to, or for the account of, any of its branch offices or the office 
of an affiliate of Lender.

           (F)  Calculation of all amounts payable to Lender under 
Section 2.11 shall be made though Lender had actually funded the relevant 
LIBOR Rate Revolving Loan through the purchase of a LIBOR deposit bearing 
interest at the LIBOR Rate in an amount equal to the amount of that LIBOR 
Rate Revolving Loan and having a maturity comparable to the relevant Interest 
Period and through the transfer of such LIBOR deposit from an offshore office 
to a domestic office in the United States of America; provided, however, that 
Lender may fund each of the LIBOR Rate Revolving Loan in any manner it sees 
fit and the foregoing assumption shall be utilized only for the calculation 
of amounts payable under Section 2.11.

           (G)  Notwithstanding any of the foregoing, Borrower shall not 
be entitled to exercise its option to convert any portion of the Revolving 
Loan to a LIBOR Rate Revolving Loan until the earlier of (i) January 31, 1998 
or (ii) receipt of TRO Leaning, Inc.'s audited annual financial statements 
for the fiscal year ended October 31, 1997 containing the unqualified opinion 
of its auditors.

     2.12  PURPOSES.

           (A)  The purpose of the Revolving Loan is to provide Borrower with 
(i) working capital financing and (ii) the funds necessary on the Origination 
Date to have refinanced Borrower's existing loan facility with Harris Trust 
and Savings Bank.

           (B)  The purpose of the Term Loan is to provide Borrower with (i) 
funds to reduce the principal amount of the Revolving Loan, and (ii) funds to 
satisfy certain of its fees and expenses.

4. PAYMENTS.

   4.1.  REVOLVING LOAN ACCOUNT: METHOD OF MAKING PAYMENTS. Lender shall 
maintain a loan account (the "Revolving Loan Account") on its books in which 
shall be recorded (i) all loans and advances made by Lender to Borrower 
pursuant to this Agreement, (ii) all payments made by Borrower on all such 
loans and advances and (iii) all other appropriate debits and credits as 
provided in this Agreement, including, without limitation, all fees, charges, 
expenses and interest. All entries in the Revolving Loan Account shall be 
made in accordance with Lender's customary accounting practices as in effect 
from time to time. Unless otherwise agreed to in writing from time to time 
hereafter, all payments which Borrower is required to make to Lender under 
this Agreement or under any of the Ancillary Agreements shall be made by 
appropriate debits to the Revolving Loan Account. Lender may, in its sole and 
absolute discretion, elect to bill Borrower for such amounts in which case 
the amount shall be immediately due and payable with interest thereon at the 
rate set forth at the Base Rate.

   4.2.  PAYMENT TERMS. All of the Liabilities shall be payable to Lender at 
the address set forth in Section 13.10. The Liabilities will be repayable as 
follows: (i) interest shall be payable on the first day of each month (for 
the immediately preceding month), (ii) fees, costs, expenses and similar 
charges shall be payable as and when provided for in this Agreement or the 
Ancillary Agreements and (iii) the principal balance of the Liabilities shall 
be payable as and when provided for in this Agreement or the Ancillary 
Agreements, including without limitation, collections received with respect 
to any proceeds of Collateral as such proceeds are received; provided, 
however, that if at any time the (i) outstanding principal balance of the 
Revolving Loan exceeds the lesser of $18,000,000 (or such lesser amount of 
the Maximum Amount of the Revolving Loan then in effect) or the Borrowing Base 
or (ii) the outstanding principal balance of all of the Liabilities exceeds 
the Total Facility, Borrower shall immediately pay to Lender without demand 
such amount as is necessary to eliminate such excess.

                             22



   4.3.  COLLECTION OF ACCOUNTS AND PAYMENTS. Borrower shall establish: (i) a 
lock box account (the "Lock Box Account") in Lender's name with Harris Trust 
and Savings Bank and (ii) a special deposit account (the "Special Deposit 
Account") in Lender's name with a depository bank reasonably satisfactory to 
Lender (collectively, the "Depository Banks") into which Borrower and/or 
Borrower's Account Debtors will immediately deposit all remittances and 
proceeds of the Collateral in the identical form in which such payment was 
made; provided, however, if such remittance was made in the form of cash, 
Borrower may deposit said remittance with the Depository Banks in the form of 
a check. Notwithstanding the foregoing, Borrower may only deposit into the 
Special Deposit Account wire transfers Borrower receives from foreign Account 
Debtors; all other deposits to be made into the Lock Box Account. Depository 
Banks shall acknowledge and agree, in a manner satisfactory to Lender, that 
all payments made to the Lock Box Account and the Special Deposit Account are 
the sole and exclusive property of Lender, that Depository Banks have no 
rights of setoff against the funds in the Lock Box Account and that 
Depository Banks will wire, or otherwise transfer deposited funds in a manner 
satisfactory to Lender, funds deposited in the Lock Box Account and in the 
Special Deposit Account to Lender on a daily basis as soon as such funds are 
collected, all pursuant to the Lock Box Agreement in the form of Exhibit 1.53 
attached hereto and the Special Deposit Agreement in the form of Exhibit 1.78 
attached hereto. Borrower hereby agrees that all payments made to the Lock 
Box Account and the Special Deposit Account or otherwise received by Lender, 
whether on the Accounts or as proceeds of other Collateral or otherwise, will 
be the sole and exclusive property of Lender and will be applied on account 
of the Liabilities. After allowing two (2) Business Days for collection after 
such funds are received by Lender, Lender will credit (conditional upon final 
collection) all payments received through the Lock Box Account and the 
Special Deposit Account to the Revolving Loan Account. Borrower and any 
Affiliates, shareholders, directors, officers, employees, agents of Borrower 
and all Persons acting for or in concert with Borrower shall, acting as 
trustee for Lender, receive, as the sole and exclusive property of Lender, any 
monies, checks, notes, drafts or any other payments relating to or proceeds 
of Accounts or other Collateral which come into their possession or under 
their control and immediately upon receipt thereof, shall remit the same or 
cause the same to be remitted, in kind, to Lender, to the Lock Box Account or 
the Special Deposit Account or at Lender's address set forth in Section 
13.10. Borrower agrees to pay to Lender any and all fees, costs and expenses 
(if any) which Lender incurs in connection with opening and maintaining the 
Lock Box Account and the Special Deposit Account and depositing for 
collection by Lender any check or item of payment received or delivered to 
Depository Banks or Lender on account of the Liabilities and Borrower further 
agrees to reimburse Lender for any claims asserted by Depository Banks in 
connection with the Lock Box Account and the Special Deposit Account or any 
returned or uncollected checks received by Depository Bank for deposit in the 
Lock Box Account and the Special Deposit Account, except claims relating to 
or caused by the malfeasance, recklessness or negligence of Lender.

   4.4.  APPLICATION OF PAYMENTS AND COLLECTIONS. Borrower irrevocably waives 
the right to direct the application of payments and collections received by 
Lender from or on behalf of Borrower, and Borrower agrees that Lender shall 
have the continuing exclusive right to apply and reapply any and all such 
payments and collections against the Liabilities in such manner as Lender may 
deem appropriate, notwithstanding any entry by Lender upon any of its books 
and

                                 23




records. To the extent that Borrower makes a payment or payments to Lender or 
Lender receives any payment or proceeds of the Collateral for Borrower's 
benefit, which payment(s) or proceeds or any part thereof are subsequently 
invalidated, declared to be fraudulent or preferential, set aside or required 
to be repaid to a trustee, receiver or any other party under any bankruptcy 
act, state or federal law, common law or equitable cause, then, to the extent 
of such payment or proceeds received, the obligations to make such payments 
shall continue in full force and effect, as if such payments or proceeds had 
not been received by Lender.

    4.5.  STATEMENTS.  All advances to Borrower, and all other debits and 
credits provided for in this Agreement, shall be evidenced by entries made by 
Lender in its internal data control systems showing the date, amount and 
reason for each such debit or credit. Until such time as Lender shall have 
rendered to Borrower written statements of account as provided herein, the 
balance in the Revolving Loan Account, as set forth on Lender's most recent 
statement, shall be rebuttably presumptive evidence of the amounts due and 
owing to Lender by Borrower. Not less than ten (10) days after the final day 
of each calendar month, Lender shall render to Borrower a statement setting 
forth the balance of the Revolving Loan Account, including principal, 
interest, expenses and fees. Each such statement shall be subject to 
subsequent adjustment by Lender and Lender's right to reapply payments in 
accordance with Section 4.4, but shall, absent manifest errors or omissions, 
be presumed correct and binding upon Borrower and shall constitute an account 
stated unless, within thirty (30) days after receipt of any statement from 
Lender, Borrower shall deliver to Lender written objection thereto specifying 
the error or errors, if any, contained in such statement.

5.  COLLATERAL: GENERAL TERMS.

    5.1.  SECURITY INTEREST AND MORTGAGE.  To secure the prompt payment to 
Lender of the Liabilities, Borrower hereby grants to Lender a continuing 
security interest in and to all of the following property and interest in 
property of Borrower, whether now owned or existing or hereafter acquired or 
arising and wherever located: (i) all Accounts, Inventory, Equipment, 
vehicles, contract rights, General Intangibles, tax refunds, chattel paper, 
instruments, letters of credit, documents and documents of title; (ii) all of 
Borrower's deposit accounts (general or special) with and credits and other 
claims against Depository Bank or Lender, or any other financial institutions 
with which Borrower maintains deposits; (iii) all of Borrower's now owned or 
hereafter acquired monies, and any and all other property of Borrower now or 
hereafter coming into the actual possession, custody or control of Lender or 
any agent or affiliate of Lender in any way or for any purpose (whether for 
safekeeping, deposit, custody, pledge, transmission, collection or 
otherwise); (iv) all insurance and condemnation proceeds of or relating to 
any of the foregoing; (v) all of Borrower's books and records relating to any 
of the foregoing; and (vi) all accessions and additions to, substitutions for, 
and replacements, products and proceeds of any of the foregoing.

    5.2.  DISCLOSURE OF SECURITY INTEREST.  Borrower shall make appropriate 
entries upon its financial statements and books and records disclosing 
Lender's security interest in the Collateral.

                                      24



    5.3.  SPECIAL COLLATERAL. Immediately upon Borrower's receipt of any 
Collateral which is evidenced or secured by an agreement, chattel paper, 
letter of credit, instrument or document, including, without limitation, 
promissory notes, documents of title and warehouse receipts (the "Special 
Collateral"), Borrower shall deliver the original thereof to Lender or to 
such agent of Lender as Lender shall designate, together with appropriate 
endorsements, the documents required to draw thereunder (as may be relevant 
to letters of credit) or other specific evidence (in form and substance 
acceptable to Lender) of assignment thereof to Lender.

    5.4.  FURTHER ASSURANCES.  At Lender's request, Borrower shall, from time 
to time, (i) execute and deliver to Lender all Security Documents that Lender 
may reasonably request, in form and substance acceptable to Lender, and pay 
the costs of any recording or filing of the same and (ii) take such other 
actions as Lender may reasonably request in order to fully effect the 
purposes of this Agreement and to protect Lender's interest in the 
Collateral. Upon the occurrence of any Default, Borrower hereby irrevocably 
makes, constitutes and appoints Lender (and all Persons designated by Lender 
for that purpose) as Borrower's true and lawful attorney and agent-in-fact to 
sign the name of Borrower on any of the Security Documents and to deliver any 
of the Security Documents to such Persons as Lender, in its sole discretion, 
may elect. Borrower agrees that a carbon, photographic, photostatic, or other 
reproduction of this Agreement or of a financing statement is sufficient as a 
financing statement.

    5.5.  INSPECTION AND FIELD REVIEWS.  Lender (by any of its officers, 
employees or agents) shall have the right, at any time or times during 
Borrower's usual business hours, without prior notice, to inspect and perform 
field reviews with regard to the Collateral, the Borrowing Base and all books 
and records related thereto (and to make extracts from such records) and the 
premises upon which any of the Collateral is located, to discuss Borrower's 
affairs and finances with any Person (including Borrower's independent 
certified public accountants) and to verify the amount, quality, value and 
condition of, or any other matter relating to, the Collateral. 
Notwithstanding the foregoing, provided that there does not then exist a 
Default or an Event of Default, Lender shall limit its inspections and field 
reviews to not more than four (4) times during each Contract Year. Borrower 
agrees to pay all of Lender's out-of-pocket costs and expenses plus a sum 
equal to $500.00 per person, per day, for each person participating in such 
field review/inspection.

    5.6.  LOCATION OF COLLATERAL.  Borrower's chief executive office, 
principal place of business and all other offices and locations of the 
Collateral and books and records related thereto (including, without 
limitation, computer programs, printouts and other computer materials and 
records concerning the Collateral) are set forth on Exhibit 3.3(B) attached 
hereto. Borrower shall not remove its books and records or the Collateral 
from any such locations (except for removal of items of Inventory upon its 
sale in accordance with the terms of this Agreement) and shall not open any 
new offices or relocate any of its books and records or the Collateral except 
within the continental United States of America with at least thirty (30) 
days prior notice thereof to Lender.

    5.7.  LENDER'S PAYMENT OF CLAIMS ASSERTED AGAINST BORROWER.  Lender may, 
but shall not be obligated to, at any time or times hereafter, in its 
reasonable discretion, and without

                                       25






waiving any Default or waiving or releasing any obligation, liability or duty 
of Borrower under this Agreement or the Ancillary Agreements, pay, acquire or 
accept an assignment of any security interest, lien, claim or other 
encumbrance asserted by any Person against the Collateral. All sums paid by 
Lender under this Section 5.7, including all costs, fees (including without 
limitation reasonable attorneys' fees and paralegals' fees and court costs), 
expenses and other charges relating thereto, shall be payable by Borrower to 
Lender on demand and shall be additional Liabilities secured by the 
Collateral.

6. COLLATERAL: ACCOUNTS.

     6.1.  VERIFICATION OF ACCOUNTS. Any of Lender's officers, employees or 
agents shall have the right, at any time or times hereafter, in Lender's or 
Borrower's name or in the name of a firm of independent certified public 
accountants acceptable to Lender, to verify the validity, amount or any other 
matters relating to any Accounts by mail, telephone, telegraph or otherwise.

     6.2.  ASSIGNMENTS, RECORDS AND ACCOUNTS REPORT. Borrower shall keep 
accurate and complete records of its Accounts and as frequently as Lender 
shall require, but not less frequently than: (a) once per week (on or before 
the following Tuesday), Borrower shall deliver to Lender an Accounts Report 
regarding its Accounts for the preceding week, together with, upon Lender's 
request, copies of the invoices related thereto; and (b) once per month (on 
or before the twentieth (20th) day of each said calendar month), Borrower 
shall deliver to Lender an Accounts Report regarding its Installment Accounts 
for the preceding month, together with, upon Lender's request, copies of the 
invoices related thereto. Borrower shall also deliver to Lender, upon demand, 
the original copy of all documents, including, without limitation, repayment 
histories, present status reports and shipment reports, relating to the 
Accounts included in any Accounts Report and such other matters and 
information relating to the status of then existing Accounts as Lender shall 
reasonably request.

     6.3.  NOTICE REGARDING DISPUTED ACCOUNTS. Borrower shall give Lender 
prompt notice of any Accounts individually or in the aggregate in excess of 
$50,000 at any time or from time to time which are in dispute between any 
Account Debtor and Borrower. Each Accounts Report shall identify all disputed 
Accounts and disclose with respect thereto, in reasonable detail, the reason 
for the dispute, all claims related thereto and the amount in controversy.

     6.4.  SALE OR ENCUMBRANCE OF ACCOUNTS. Borrower shall not, without the 
prior written consent of Lender, sell, transfer, grant a security interest in
or otherwise dispose of or encumber any of its Accounts to any Person other 
than Lender.

7. COLLATERAL: INVENTORY.

     7.1.  SALE OF INVENTORY. Unless a Default occurs, and Lender directs 
otherwise, Borrower may sell Inventory in the ordinary course of its business 
(which does not include a transfer in partial or total satisfaction of 
Indebtedness, sales in bulk, sale on consignment or sales on an approval or 
sale or return basis). All proceeds of such sales shall be part of the 
Collateral


                                      26



and remitted to the Special Deposit Account. Borrower shall not rent, lease 
or otherwise transfer or dispose of any of the Inventory without Lender's 
prior written consent, except as set forth in this Section 7.1.

     7.2.  SAFEKEEPING OF INVENTORY: INVENTORY COVENANTS. Borrower shall 
maintain all Inventory in good and salable condition at all times. Lender 
shall not be responsible for (i) the safekeeping of the Inventory; (ii) any 
loss or damage thereto or destruction thereof occurring or arising in any 
manner or fashion, except when caused by the failure of Lender or its agents 
to exercise reasonable care with respect to the Inventory during any period 
of time during which Lender has foreclosed upon and owns good title to such 
Inventory; (iii) any diminution in the value of Inventory or (iv) any act or 
default of any carrier, warehouseman, bailee or forwarding agency or any 
other Person in any way dealing with or handling the Inventory. All risk of 
loss, damage, distribution or diminution in value of the Inventory shall be 
borne, as between Borrower and Lender, by Borrower, except as provided 
in clause (ii) above.

     7.3.  RECORDS AND SCHEDULES OF INVENTORY. Borrower shall keep correct and
accurate records on a first-in, first-out basis, itemizing and describing the 
kind, type, quality and quantity of Inventory, Borrower's cost therefor and 
selling price thereof, and the withdrawals therefrom and additions thereto 
and Inventory then on consignment (if any, provided that Lender's prior 
written consent to such consignment must be obtained), and shall furnish to 
Lender, monthly on or before the twentieth (20th) day of each month, a 
current updated Inventory Report for the preceding month, based on the FIFO 
cost assumption. A complete physical count of the Inventory shall be 
conducted no less than annually and a report based on such count of the 
Inventory shall promptly thereafter be provided to Lender together with such 
supporting information as Lender shall request, including, without 
limitation, invoices relating to Borrower's purchase of goods listed in said 
report, as Lender shall, in its reasonable discretion, request.

     7.4.  RETURNED AND REPOSSESSED INVENTORY. If at any time prior to the 
occurrence of a Default, any Account Debtor returns any of the Inventory to 
Borrower, Borrower shall promptly determine the reason for such return and, 
if Borrower accepts such return, issue a credit memorandum (with a copy to be 
immediately sent to Lender) in the appropriate amount to such Account Debtor; 
provided, however, that Borrower shall not, without the prior consent of 
Lender, which consent shall not be unreasonably withheld when such consent is 
not inconsistent with protecting Lender's security interest in the 
Collateral, accept on any single day, returned Inventory the sale price of 
which was in excess of $75,000 in the aggregate or a total amount aggregating 
in excess of $150,000 in any thirty (30) day period. After the occurrence of 
a Default, and if Lender so directs, Borrower shall hold all returned 
Inventory in trust for Lender, shall segregate all returned Inventory from 
all other property of Borrower or in Borrower's possession and shall 
conspicuously label such returned Inventory as the property of Lender. 
Borrower shall, in all cases, immediately notify Lender of the return of any 
Inventory with a value in excess of $75,000, specifying the reason for such 
return and the location and condition of the returned Inventory.

     7.5.  EVIDENCE OF OWNERSHIP OF INVENTORY. Borrower shall, upon Lender's 
request, deliver to Lender all evidence of ownership of the Inventory.


                                      27



8.   COLLATERAL: EQUIPMENT.

     8.1.  MAINTENANCE OF THE EQUIPMENT. Borrower shall keep and maintain the 
Equipment in good operating condition and repair, ordinary wear and tear 
excepted, and shall make all necessary replacements thereof so that the 
value, utility and operating efficiency thereof shall at all times be 
maintained and preserved, ordinary wear and tear excepted, and shall promptly 
inform Lender of any additions to or deletions from the Equipment. Borrower 
shall not permit any such items to become affixed to real estate in such 
manner that such items of Equipment will become a fixture or an accession to 
other personal property.

     8.2.  EVIDENCE OF OWNERSHIP OF EQUIPMENT. Borrower shall, upon Lender's 
request, deliver to Lender all evidence of ownership of the Equipment 
(including, without limitation, bills of sale, invoices, certificates of 
title and applications for title).

     8.3.  PROCEEDS OF THE EQUIPMENT. Borrower shall not sell, transfer, 
lease, grant a security interest in or otherwise dispose of or encumber the 
Equipment or any part thereof to any Person other than Lender except for 
purchase money liens (including capitalized leases and other forms of 
installment purchase financing) granted to the Person financing a purchase 
of Equipment so long as the lien granted is limited to the specific fixed 
assets so acquired, the aggregate amount of indebtedness secured by all such 
liens as a result of purchases shall not exceed One Hundred Thousand Dollars 
($100,000) at any time during the term hereof, and the transaction does not 
violate any other provision of this Agreement (notification of such purchase 
money lien to be provided within ten (10) days of acquisition of such fixed 
asset); provided, however, that in any Fiscal Year of Borrower, Borrower may 
sell or otherwise dispose of any single piece of Equipment with a net book 
value not to exceed $150,000 so long as all Equipment disposed of in any 
Fiscal Year of Borrower does not have a net book value in excess of $300,000 
in the aggregate. In the event any Equipment is sold, transferred or 
otherwise disposed of as permitted in this Section 8.3, Borrower shall 
promptly notify Lender of such fact and deliver all of the cash proceeds of 
such sale, transfer or disposition to Lender, which proceeds shall be applied 
in accordance with Section 2.8(C) hereof, provided, however, that with 
Lender's prior written consent Borrower may use the proceeds of such sale, 
transfer or disposition to finance the purchase of replacement Equipment in 
which Lender has a first perfected security interest documented to the 
satisfaction of Lender and its counsel. Borrower shall deliver to Lender 
written evidence of the use of the proceeds for such purchase. All 
replacement Equipment purchased by Borrower shall be free and clear of all 
liens, claims, security interests and other encumbrances, except for the 
security interest granted to Lender or purchase money security interests 
consented to in writing by Lender.

          (E)  To the best of Borrower's Knowledge, there are no facts, events

    9.3.  INVENTORY WARRANTIES AND REPRESENTATIONS. Borrower warrants and 
represents that Lender may rely, in determining which items of Inventory 
listed on any Inventory Report are Eligible Inventory, without independent 
investigation, on all statements, warranties and representations made by 
Borrower on or with respect to any such Inventory Report and, unless

or is Inventory which is in transit and is so identified on the relevant 
Inventory Report;

          (B)  The Inventory has been produced in full compliance with all

shall not at any time or times hereafter be, stored with a bailee, 
warehouseman or similar party without Lender's prior written consent and, if 
Lender gives such consent, Borrower will concurrently therewith cause any 
such bailee, warehouseman or similar party to issue and deliver to Lender, in 
form and substance acceptable to Lender, warehouse receipts therefor in 
Lender's name; and

          (D)  Borrower is the owner of all of the Inventory free and clear of 
all claims, liens and encumbrances except those of Lender and none of the 
Inventory has been leased, rented, transferred or sold, either on

    9.4.  ERISA WARRANTIES AND REPRESENTATIONS. Borrower warrants and 
represents that:

          (A)  Exhibit 9.4 hereto lists all the Employee Benefit Plans.

          (B)  Each Employee Benefit Plan is in compliance in all material 
respects with its terms and with the applicable provisions of ERISA and the 
Code, except where the failure to so comply would not have a material (in the 
reasonable opinion of Lender) adverse effect on the financial condition or 
results or operations of Borrower, and each such Employee Benefit Plan that 
is intended to be qualified under Section 401(a) of the Code has been 
determined by the Internal Revenue Service to be so qualified (or, consistent 
with Section 1140 of the Tax Reform Act of 1986, has been submitted to the 
Internal Revenue Service for such a determination within the applicable 
remedial amendment period), and each trust related to any such Employee 
Benefit Plan has been determined to be exempt from federal income tax under 
Section 501(a) of the Code or submitted to the Internal Revenue Service for 
such a determination;


                                     33




           (C) Except as set forth in Exhibit 9.4, no Employee Benefit Plan 
has an actuarial present value of projected benefit obligations that exceeds 
the fair market value of the net assets available for such benefits, 
calculated on the basis of the actuarial assumptions specified in the most 
recent actuarial valuation for such Employee Benefit Plan, and no such 
Employee Benefit Plan provides for subsidized early retirement benefits that, 
in the event of a reduction in force or plant closing, would have a material 
(in the reasonable opinion of Lender) adverse effect on the financial 
condition or results or operations of Borrower;

           (D) Except as set forth on Exhibit 9.4, no Employee Benefit Plan 
is an employee welfare benefit plan within the meaning of Section 3(1) of 
ERISA that provides benefits to employees after termination of employment 
other than as required by Section 601 of ERISA;

           (E) Neither Borrower nor any of its ERISA Affiliates has breached 
in any material respect any of the responsibilities, obligations, or duties 
imposed on them by ERISA or the regulations promulgated thereunder with 
respect to any Employee Benefit Plan, which breach would have a material (in 
the reasonable opinion of Lender) adverse effect on the financial condition 
or results or operations of Borrower;

           (F) Neither Borrower nor any ERISA Affiliate has (i) failed to 
make a required contribution or payment to a Multiemployer Plan or (ii) made 
a complete or partial withdrawal under Sections 4203 or 4205 of ERISA from a 
Multiemployer Plan, where such failure or complete or partial withdrawal 
would have a material (in the reasonable opinion of Lender) adverse effect on 
the financial condition or results or operations of Borrower;

           (G) At the date hereof, the aggregate potential withdrawal 
liability, as determined in accordance with Title IV of ERISA, of Borrower 
and any ERISA Affiliates with respect to all Employee Benefit Plans that are 
Multiemployer Plans would not have a material (in the reasonable opinion of 
Lender) adverse effect on the financial condition or results or operations of 
Borrower and, to the best of Borrower's and its ERISA Affiliates' knowledge, 
no Multiemployer Plan is in reorganization or insolvent within the meaning of 
Section 4241 or 4245 of ERISA;

           (H) Neither Borrower nor any ERISA Affiliate has failed to make a 
required installment or any other required payment under Section 412 of the 
Code on or before the due date for such installment or other payment;

           (I) Neither Borrower nor any ERISA Affiliate is required to 
provide security to an Employee Benefit Plan under Section 401(a)(29) of the 
Code due to an Employee Benefit Plan amendment that results in an increase in 
current liability for the plan year;

           (J) No liability to the PBGC has been, or is expected by Borrower 
or any ERISA Affiliate to be, incurred by Borrower or any ERISA Affiliate, 
which liability would have a material (in the reasonable opinion of Lender) 
adverse effect on the financial condition or results or operations of 
Borrower, and there are no premium payments that have become due and which 
are unpaid;

                                   34



           (K) No events have occurred in connection with any Employee Benefit 
Plan that might constitute grounds for the termination of any such Employee 
Benefit Plan by the PBGC or for the appointment by any United States District 
Court of a trustee to administer any such Employee Benefit Plan;

           (L) Except as set forth in Exhibit 9.4, no Reportable Event has, 
in the case of any Employee Benefit Plan other than a Multiemployer Plan, 
occurred and is continuing, or to the best of Borrower's knowledge, has 
occurred and is continuing in the case of any such Employee Benefit Plan that 
is a Multiemployer Plan;

           (M) No Employee Benefit Plan had an Accumulated Funding 
Deficiency, whether or not waived, as of the last day of the most recent 
fiscal year of such Employee Benefit Plan or, in the case of any 
Multiemployer Plan, as of the most recent fiscal year of such Multiemployer 
Plan for which the annual reports of such Multiemployer Plan's actuaries and 
auditors have been received; and

           (N) Borrower has not engaged in a Prohibited Transaction, which 
Prohibited Transaction would have a material (in the reasonable opinion of 
Lender) adverse effect on the financial condition or results or operations of 
Borrower.

     9.5.  AUTOMATIC WARRANTY AND REPRESENTATION AND REAFFIRMATION OF 
WARRANTIES AND REPRESENTATIONS. Each request for an advance made by Borrower 
pursuant to this Agreement or the Ancillary Agreements shall constitute (i) 
an automatic warranty and representation by Borrower to Lender that there 
does not then exist a Default or an Event of Default and (ii) a reaffirmation 
as of the date of said request of all of the warranties and representations 
of Borrower contained in this Agreement and in the Ancillary Agreements.

     9.6   SURVIVAL OF WARRANTIES AND REPRESENTATIONS. Borrower covenants, 
warrants and represents to Lender that all representations and warranties of 
Borrower contained in this Agreement and the Ancillary Agreements shall be 
true at the time of Borrower's execution of this Agreement and the Ancillary 
Agreements, and shall survive the execution, delivery and acceptance hereof 
and thereof by the parties thereto and the closing of the transactions 
described herein and therein or related hereto or thereto.

10.  COVENANTS AND CONTINUING AGREEMENTS.

Lender consents in writing otherwise:

shall have Leverage of less than 1:1. For purposes hereof, the term 
"Leverage" shall be defined as the ratio of Total Liabilities to 
Shareholder's Equity. For purposes hereof, the term "Total Liabilities" shall 
be defined as, at any date, all liabilities of Borrower and its subsidiaries 
that, in accordance with generally accepted accounting principles, should be

                                 35




term "Shareholder's Equity" shall be defined as, at any date, the 
shareholder's equity of Borrower and its subsidiaries that, in accordance 
with generally accepted accounting principles, should be classified as

whether or not so classified. Lender agrees that this financial covenant 
shall be measured only on the last day of each Fiscal Year of Borrower.

         (B)  Borrower shall maintain Operating Profit, measured quarterly on 
the last day of each fiscal quarter of Borrower, on a cumulative, 
year-to-date basis.

all income taxes included as an expense of Borrower in determining Net Income 
for such period, PLUS (c) interest deducted as an expense of Borrower in the 
determination of Net Income for such period, determined in accordance with

explosion, sprinklers, flood, business interruption, boiler and all other 
hazards and risks which are specified by Lender from time to time by 
obtaining policies naming Lender as Lender's loss payee, mortgagee and 
additional insured (none of which shall be cancelable or subject to 
modification without at least thirty (30) days notice to Lender) in coverage, 
form and amount and with companies satisfactory to Lender and at Lender's 
request will deliver each policy or certificate or insurance together with 
the applicable Lender's loss payee endorsement to Lender. In addition, 
Borrower will deliver renewals for all of such policies at least thirty (30) 
days prior to the expiration date of the subject policy. Without limiting the 
generality of the foregoing, unless otherwise agreed in writing by Lender, 
all of such policies shall (i) provide that no act of any person other than

expiration date of the subject policy;

     (G) Upon Borrower's learning thereof, notify Lender promptly and in no

financial statements;

          (M)  Give written notice to Lender within ten (10) days of receipt 
of any notice that (i) the operations of Borrower, any other obligor or any 
Subsidiary are not in full compliance with requirements of applicable

or any Subsidiary are subject to any Environmental Lien;

          (N)  Without limiting the generality of any of Borrower's other 
covenants and agreements, the operations of Borrower, any other obligor and 
each of Borrower's Subsidiaries shall at all times comply in all material 
respects with all applicable Environmental Laws. The materiality standard 
used in this Section 10.1(N) shall be exceeded if the facts giving rise to a 
breach or breaches of the covenant contained herein might result in liability 
in excess of $50,000 in the aggregate, whether or not such liability may be 
covered by insurance; and

          (O)  Promptly provide Lender with all documents requested by Lender 
which are required from time to time by federal regulations and/or regulators.

     10.2 NEGATIVE COVENANTS. Borrower covenants that it shall not, without 
the prior written consent of Lender, which consent shall not be unreasonably 
withheld where granting such consent is not inconsistent with protecting 
Lender's security interest in the Collateral:

          (A)  Merge or consolidate with, purchase, lease or otherwise 
acquire all or substantially all of the assets or properties of, or acquire 
any capital stock, equity interests, debt or other securities of, any Person

Affiliate, officer or employee of Borrower, other than with respect to the 
ordinary course of Borrower's business;

          (D)  Except as specifically permitted herein, make any material 
change in Borrower's capital structure or materially change the nature of 
Borrower's business in which it is presently engaged, or purchase or invest, 
directly or indirectly, in any assets or property (other than in the ordinary 
course of business) which are useful in, necessary for and are to be used in 
its business as presently conducted, except: (i) the contemplated sale of the 
Aviation Training Systems for an amount not less than Two Million Dollars 
($2,000,000) to which Lender expressly consents on the condition that all 
sale proceeds are paid to Lender and that such sale would not otherwise cause 
a Default hereunder; and (ii) the raising of additional equity through a public 
offering or private placement of Borrower's common stock;

          (E)  Enter into, or be a party to, any transaction or agreement,

agreements to pay salary and similar compensation to Borrower's employees in 
the ordinary course of and pursuant to the reasonable requirements of 
Borrower's business and upon fair and reasonable terms which are fully 
disclosed to Lender and are no less favorable to Borrower than would obtain 
in a comparable arm's length transaction with a Person not an Affiliate, 
director, officer or Stockholder of Borrower;

      (F)  Enter into any transaction which materially and adversely affects 
the Collateral or Borrower's ability to repay the Indebtedness or permit a 
modification of any kind or nature with respect to any Account which 
materially and adversely affects the Collateral, including any of the terms 
relating thereto, except for credits given for Inventory returned pursuant to 
Section 7.4;

      (G)  Guarantee or otherwise, in any way, become liable with respect to 
the obligations or liabilities of any Person, except (i) its Affiliates'

sell, lease or otherwise dispose of or transfer, whether by sale, merger, 
consolidation, liquidation, dissolution, or otherwise, any of Borrower's 
properties, assets, rights or businesses or the Collateral, except sales of 
Installment Accounts for cash on a non-recourse basis or, with the written 
consent of Lender, on a recourse basis to Borrower if: (i) sales proceeds 
thereof are paid to Lender and are in an amount sufficient to pay all of the 
Liabilities relating to such Installment Accounts, and (ii) such sale would 
not otherwise cause a Default hereunder;

conditions reasonably acceptable to Lender which is unsecured or secured by 
assets other than the Collateral and in each case is to Persons who execute 
and deliver to Lender (in form and substance acceptable to Lender and its

to the payment of the Liabilities ("Permitted Subordinated Indebtedness"), 
and (iii) purchase money financing, to the extent that it is permitted herein 
(collectively, the "Permitted Indebtedness");

      (K)  Permit any Accounts owing to Borrower from any Affiliate to be 
payable on terms which would not allow Borrower to demand payment upon the 
occurrence of a default or permit the aggregate amount of all Accounts owing

10.2(K) unless a Default has occurred in which case Borrower shall permit no 
Accounts to be owing from its Affiliates;

      (L)  Materially modify, amend or supplement Borrower's Articles of

direct a major portion of the business or assets of Borrower;

      (N)  Alter or amend the commencement date or termination date of any 
Fiscal Year without the prior written consent of Lender, which shall not be 
unreasonably withheld;

      (O)  Do any of the following:

           (i)  Establish, maintain, or operate any Employee Benefit Plan 
that is not in compliance in all material respects with the provisions of 
ERISA, the Code, and all other applicable laws, and the regulations and

have a material (in the reasonable opinion of Lender) adverse effect on the 
financial condition or results or operations of Borrower;

           (ii)  Allow to exist any Accumulated Funding Deficiency with 
respect to any Employee Benefit Plan, which would have a material (in the 
reasonable opinion of Lender) adverse effect on the financial condition or 
results or operations of Borrower;

           (iii)  Terminate any Employee Benefit Plan, or withdraw or effect 
a partial withdrawal from any Multiemployer Plan, if such termination, 
withdrawal, or partial withdrawal would have a material (in the reasonable 
opinion of Lender) adverse effect on the financial condition or results or 
operations of Borrower;

           (iv)  Fail to make any contribution or payment to any 
Multiemployer Plan which Borrower or any ERISA Affiliate may be required to 
make under any agreement relating to such Multiemployer Plan, which failure 
would have a material (in the reasonable opinion of Lender) adverse effect 
on the financial condition or results or operations of Borrower;

           (v)  Fail to make any required installment or any other payment 
required under Section 412 of the Code on or before the due date for such

reasonable opinion of Lender) adverse effect on the financial condition or 
results or operations of Borrower;

           (vi)  Amend any Employee Benefit Plan so as to result in an 
increase in current liability for the plan year such that Borrower or any 
ERISA Affiliate is required to provide security to such Employee Benefit Plan 
under Section 401(a)(29) of the Code;

           (vii)  Enter into any Prohibited Transaction, which Prohibited 
Transaction would have a material (in the reasonable opinion of Lender) 
adverse effect on the financial condition or results or operations of 
Borrower;


                                      43


                  (viii)  Permit the occurrence of any Reportable Event, 
which would have a material (in the reasonable opinion of Lender) adverse 
effect on the financial condition or results or operation of Borrower; or

                  (ix)    Allow or permit to exist with respect to any 
Employee Benefit Plan any other event or condition known or which reasonably 
should be known to Borrower and which would have a material (in the 
reasonable opinion of Lender) adverse effect on the financial condition or 
results or operations of Borrower; or

             (P)  Issue any Stock, other than common Stock, without Lender's 
prior written consent, which shall not be unreasonably withheld.

      10.3  CONTESTING CHARGES. Notwithstanding anything to the contrary 
herein, Borrower may dispute any Charges without prior payment thereof, even 
if such non-payment may cause a lien to attach to Borrower's assets, provided 
that Borrower shall give Lender prompt notice of such dispute and shall be 
diligently contesting the same in good faith and by an appropriate proceeding 
and there is no danger of a loss or forfeiture of any of the Collateral and 
provided further that, if the same are potentially or actually in excess of 
$50,000 in the aggregate at any time hereafter, Borrower shall give Lender 
such additional collateral and assurances as Lender, in its reasonable 
discretion, deems necessary under the circumstances, immediately upon demand 
by Lender.

      10.4  PAYMENT OF CHARGES. Subject to the provisions of Section 10.3, 
Borrower shall pay promptly when due all of the Charges. In the event 
Borrower, at any time or times hereafter, shall fail to pay the Charges or to 
promptly obtain the satisfaction of such Charges, Borrower shall promptly so 
notify Lender thereof and Lender may, without waiving or releasing any 
obligation or liability of Borrower hereunder or any Default, in its sole 
discretion, at any time or times thereafter, make such payment or any part 
thereof, (but shall not be obligated so to do) or obtain such satisfaction 
and take any other action with respect thereto which Lender deems advisable. 
All sums so paid by Lender and any expenses, including reasonable attorneys' 
fees, court costs, expenses and other charges relating thereto, shall be 
payable by Borrower to Lender upon demand and shall be additional Liabilities.

      10.5 INSURANCE: PAYMENT OF PREMIUMS. All policies of insurance on the 
Collateral or otherwise required hereunder shall be in form and amount 
satisfactory to Lender and with insurers reasonably recognized as adequate by 
Lender. Borrower shall deliver to Lender the original (or certified copy) of 
each policy of insurance and evidence of payment of all premiums therefor and 
shall deliver renewals of all such policies to Lender at least thirty (30) 
days prior to their expiration dates. Such endorsement shall provide that the 
insurance companies will give Lender at least thirty (30) days' prior notice 
before any such policy shall be altered or canceled and that no act or 
default of Borrower or any other person shall affect the right of Lender to 
all insurers under such policies to pay all proceeds payable thereunder 
directly to Lender for application against the Liabilities in the inverse 
order of maturity. Borrower irrevocably makes, constitutes and appoints 
Lender (and all officers, employees or agents designated by Lender) as 
Borrower's true and lawful attorney and agent-in-fact for the purpose of 
making, settling and

                                       44



adjusting claims under such policies, endorsing the name of Borrower in 
writing or by stamp on any check, draft, instrument or other item of payment 
for the proceeds of such policies and for making all determinations and 
decisions with respect to such policies. If Borrower shall fail to obtain or 
to maintain any of the policies required by this Agreement or to pay any 
premium relating thereto, then Lender, without waiving or releasing any 
obligation or default by Borrower hereunder, may (but shall be under no 
obligation to do so) obtain and maintain such policies of insurance and pay 
such premiums and take any other action with respect thereto which Lender 
deems advisable. All sums so disbursed by Lender, including reasonable 
attorneys' fees, court costs, expenses and other charges relating thereto, 
shall be payable by Borrower to Lender upon demand and shall be additional 
Liabilities.

      10.6 SURVIVAL OF OBLIGATIONS UPON TERMINATION OF AGREEMENT. Except as 
otherwise expressly provided for in this Agreement and in the Ancillary 
Agreements, no termination or cancellation (regardless of cause or procedure) 
of this Agreement or the Ancillary Agreements shall in any way affect or 
impair the powers, obligations, duties, rights, and liabilities of Borrower 
or Lender in any way or respect relating to any transaction or event 
occurring prior to such termination or cancellation, the Collateral, or any 
of the undertakings, agreements, covenants, warranties and representations of 
Borrower or Lender contained in this Agreement or the Ancillary Agreements. 
All such undertakings, agreements, covenants, warranties and representations 
shall survive such termination or cancellation.

11.  DEFAULT; EVENTS OF DEFAULT; RIGHTS AND REMEDIES

cure time is allowed or permitted Borrower upon the happening of any of the 
foregoing events or occurrences stated in this Section 11.1(G) if the same

     11.3  REMEDIES.  Upon and after the occurrence of a Default, Lender

Illinois Uniform Commercial Code or other applicable law, all of which rights 
and remedies shall be cumulative, and none exclusive, to the extent 
permitted by law, and in addition to any other rights and remedies 
contained in this Agreement and in any of the Ancillary Agreements;

           (B)  The right to (i) peacefully enter upon the premises of 
Borrower or any other place or places where the Collateral is located and 
kept, without any obligation to pay rent to Borrower or any other person, 
through self-help and without judicial process or first obtaining a final 
judgment or giving Borrower notice and opportunity for a hearing on the 
validity of Lender's claim, and remove the Collateral from such premises and 
places to the premises of Lender or any agent of Lender, for such time as 
Lender may require to collect or liquidate the Collateral, and/or (ii) require 
Borrower to assemble and deliver the Collateral to Lender at a place to be 
designated by Lender;

           (C)  The right to (i) open Borrower's mail and collect any and all

designated by Lender. Lender shall promptly furnish Borrower with a copy of 
any such notice sent and Borrower hereby agrees that any such notice in

Borrower shall, upon demand, co-sign such notice with Lender; and

provided in Section 11.4, in lots or in bulk, for cash or on credit, all as 
Lender, in its sole discretion, may deem advisable. At any such sale or sales 
of the Collateral, the Collateral need not be in view of those present and 
attending the sale, nor at the same location at which the sale is being 
conducted. Lender shall have the right to conduct such sales on Borrower's 
premises or elsewhere and shall have the right to use Borrower's premises 
without charge for such sales for such time or times as Lender may see fit. 
Lender is hereby granted a license or other right to use, without charge, 
Borrower's labels, patents, copyrights, rights of use of any name, trade 
secrets, trade names, trademarks and advertising matter, or any property of a 
similar nature, as it pertains to the Collateral, in advertising for sale and 
selling any Collateral and Borrower's rights under all licenses and all 
franchise agreements shall inure to Lender's benefit but Lender shall have no 
obligations thereunder. Lender may purchase all or any part of the Collateral 
at public or, if permitted by law, private sale and, in lieu of actual 
payment of such purchase price, may setoff the amount of such price against 
the Liabilities. The proceeds realized from the sale of any Collateral shall 
be applied first to the reasonable costs, expenses and attorneys' and 
paralegals' fees and expenses incurred by Lender for collection and for 
acquisition, completion, protection, removal, storage, sale and delivery of 
the Collateral; second to interest due upon any of the Liabilities; and third 
to the principal of the Liabilities. Lender shall account

                                       48




to Borrower for any surplus. If any deficiency shall arise, Borrower shall 
remain liable to Lender therefor.

     11.4  NOTICE. Borrower agrees that any notice required to be given by 
Lender of a sale, lease, other disposition of any of the Collateral or any 
other intended action by Lender, which is delivered to Borrower by: 
(i) confirmed facsimile transmission along with a copy which is deposited in 
the United States mail, postage prepaid and duly addressed to Borrower at the 
address set forth in Section 13.10, (ii) personal service, or (iii) overnight 
mail to Borrower at the address set forth in Section 13.10, at least fifteen 
(15) days prior to any such public sale, lease or other disposition or other 
action being taken, or the time after which any private sale of the 
Collateral is to be held, shall constitute commercially reasonable and fair 
notice thereof to Borrower.
