      WHEREAS, the Borrower has requested that certain changes and modifications

      1.    Definitions; References. All capitalized terms used and not

terms in the Loan Agreement. All Section, Subsection and Paragraph references

and effect.

      2.    Revolving Credit Loans.

      (A)   Paragraph (iii) of Subsection (a) of Section 2.01 and all previous
amendments thereto of the Loan Agreement is amended to read in its entirety as
follows:

            (i)   Notwithstanding anything to the contrary in the foregoing
                  paragraphs (i) and (ii), and subject to downward adjustment
                  pursuant to Paragraph 5 of this Amendment, at no time during
                  the term of this Agreement shall the aggregate amount of the
                  Lenders' Revolving Credit Commitment, or the aggregate of
                  outstanding Revolving Credit Loans plus the aggregate undrawn
                  face amount


                                       1

                  of all issued and outstanding Letters of Credit exceed
                  $8,400,000.00 (the "Revolving Credit Facility Limit"). The
                  Revolving Credit Maturity Date shall be August 1, 2003. The
                  Borrower will execute and deliver Replacement Revolving Credit
                  Notes as required by Lenders substantially in the form
                  attached as Exhibit A, and shall make aggregate payments for
                  the Revolving Credit Notes to the Agent.

      (B)   Section 2.04 and all previous amendments thereto of the Loan
Agreement is amended to read in its entirety as follows:

            (i)   The interest rate on the Revolving Credit Loans will be equal
                  to the Prime Rate, plus 1%, as adjusted from time to time
                  pursuant hereto. In the event that the Overadvance
                  (hereinafter defined) exceeds the amounts set forth in
                  paragraph 3 below, or exists in whole or in part after
                  December 31, 2002, (in either case an "Unpermitted
                  Overadvance") it shall be an Event of Default. For so long as
                  such Event of Default exists, the interest rate on the
                  Revolving Credit Loans will equal the Prime Rate, as adjusted
                  from time to time pursuant hereto, plus 3%, for the first
                  thirty days of such Unpermitted Overadvance and shall increase
                  by 1% for each and every additional thirty day period that
                  such Unpermitted Overadvance exists.

      3.    Revolving Credit Loan Borrowing Formula ("Borrowing Formula").

      (A)   Paragraph (v) of Subsection (a) of Section 2.01 of the Loan
Agreement is replaced in its entirety with the following:

            (v)(i)Notwithstanding any of the provisions of Subsection (a) of
                  Section 2.01 and any previous amendments thereto, the
                  principal amount outstanding under the Revolving Credit Loans
                  shall, at no time, exceed the sum of (X) eighty (80%) percent
                  of the net amount of Eligible Accounts Receivable (hereafter
                  defined) on the date of determination and (Y) fifty (50%)
                  percent of the net amount of Eligible Inventory (hereafter
                  defined). Notwithstanding, for the period from July 1, 2002 to
                  September 30, 2002, the Lenders will permit an Overadvance of
                  up to $500,000.00. From October 1, 2002 to December 31, 2002
                  the amount of the allowable Overadvance will be reduced to
                  $300,000.00. Beginning January 1, 2003, no Overadvance will be
                  permitted.

            (ii)  $500,000.00 of the Revolving Credit Facility Limit shall be
                  held or "blocked" to be utilized to pay the costs referenced
                  in Paragraph 5. No advance shall be made if its making would
                  cause the aggregate unpaid balance of all advances outstanding
                  under the Revolving Credit Loans to exceed $8,400,000.00
                  (subject to downward adjustment pursuant to Paragraph 5 of
                  this Amendment).

            (iii) The Borrower shall provide to the Agent, with a copy to each
                  Lender, on a monthly basis, a written borrowing base
                  certificate certifying the amount of


                                       2

                  Eligible Accounts Receivable, Eligible Inventory, outstanding
                  balance of the Revolving Credit Loans and available amount for
                  advance under the Borrowing Formula. The monthly borrowing
                  base certificate will be delivered no later than the 20th day
                  of the month immediately following the month covered by the
                  certificate. Failure to deliver the borrowing base certificate
                  in a timely manner shall constitute an Event of Default and
                  the interest rate shall adjust to the same rate as set forth
                  in paragraph 2(B)(i) above for an Unpermitted Overadvance, for
                  so long as such Event of Default exists.

      As used herein, Eligible Accounts Receivable and Eligible Inventory shall
have the following meanings:

      "Eligible Accounts Receivable" means an Account Receivable owing to
Borrower which, unless the Bank shall otherwise in its sole discretion agree,
meets with the following specifications at the time it comes into existence and
continues to meet the same until it is collected in full:

      (a)   The Account Receivable is due and payable not more than thirty (30)
days after the date of invoice therefore (or (45) days for customers that have
historically been billed on such basis), and is not more than ninety (90) days
past due;

      (b)   The Account Receivable arose from the performance of services or
sale of products by the Borrower;

      (c)   The Account Receivable is not subject to any prior assignment,
claim, lien or security interest and the Borrower will not make any further
assignment thereof or create any further security interest therein nor permit
the Borrower's rights therein to be reached by attachment, levy, garnishment or
other judicial process;

      (d)   The net value of an Account Receivable after allowable set off,
credit, or adjustment by the Account Debtor;

      (e)   Accounts Receivable shall not include: (i) amounts owed to Borrower
from any Subsidiary of Borrower; (ii) amounts due the Borrower from officers,
shareholders or employees; (iii) amounts carried on the books and records of the
Borrower as an intercompany or divisional receivable; (iv) the total receivables
owed by any Account Debtor having more than ten percent (10%) of its
indebtedness to the Borrower ninety (90) days or more past due from the date of
the invoice (excluding retainages); (v) foreign receivables other than
receivables from Canadian customers; (vi) any Account Receivable which the Bank
has reasonably determined in good faith is unsatisfactory; and (vii) retainages


                                       3

      (f)   The term "Account Receivable" shall include all accounts, accounts
receivable, contract rights for the payment of money, chattel paper, and all
other obligations and receivables now owned or hereafter acquired by the
Borrower, whether now existing or hereafter arising. All accounts receivable
shall be processed through Borrower's lock box account with Agent.

      (g)   The term "Account Debtor" includes the buyer or lessee of services
or products from the Borrower.

      (h)   The term "Eligible Inventory" shall include raw materials and
completed products, but shall not include any work in progress.

      4.    Term Loan A:

      (A)   Section 2.05 (a)(ii) and all previous amendments thereto of the Loan
      Agreement is amended to read as follows:

            (ii)  Notwithstanding anything to the contrary in the foregoing
      paragraph (i), at no time during the term of the Agreement shall the
      aggregate amount of the Lenders' Term Loan A Commitment or the aggregate
      outstanding principal balance of Term Loan A, exceed $2,921,506.00. This
      aggregate amount represents an increase in principal of $500,000.00 over
      the current amount owing under Term Loan A which will be used to reduce
      the Revolving Credit Loans.

      (B)   Paragraph 2.06 and all previous amendments thereto of the Loan
      Agreement is amended to read in its entirety as follows:

            (i)   The unpaid principal amount of Term Loan A shall bear interest
            at the Prime Rate, plus 1% (currently 5.75%) to be adjusted on the
            1st of each month, based on adjustments to the Prime Rate. An
            aggregate payment of $56,142.00 (principal and interest) will be due
            on August 1, 2002 and monthly thereafter, subject to changes due to
            adjustment of the interest rate.

            (ii) Borrower will execute and deliver Replacement Term Loan A
            Note(s) as required by Lenders, substantially in the form attached
            as Exhibit B, and shall make aggregate payments for the Term Loan A
            Notes to the Agent. The maturity date for the Term Loan A Note shall
            be August 1, 2003. Monthly payments of principal and interest shall
            be based upon a sixty month amortization schedule. The monthly
            payment of principal and interest will be adjusted on the
            above-referenced dates to amortize the then remaining principal
            balance over the remaining term. Any prepayments of any kind,
            whether mandatory or optional, shall not reduce the calculation of
            the monthly payment of principal and interest, but shall be applied
            to the reduction of the principal balance of the Term Loan so as to
            have the effect of shortening the amortization period of Term Loan
            A. For example, assuming the interest rate is 5.75% and there is no
            change in the interest rate, the monthly payment would be $56,142.00
            per month. If a prepayment is made, the monthly payment would be
            $56,142.00 per month. If a prepayment is made, the monthly payment

                                       4

            would remain at $56,142.00, but will be applied to principal and
            interest as if the amortization period for calculating loan payments
            was shortened.

      5.    Reduction of Credit Limit. If the Lease Obligations as defined in
the Sixth Amendment are less than $500,000.00, the $8,400,000.00 Revolving
Credit Facility Limit shall be permanently reduced, dollar for dollar, by the
difference between $500,000.00, and the actual costs; Borrower will provide
reasonable documentation of the Lease Obligations to the satisfaction of
Lenders. The Revolving Credit Facility Limit may be further reduced, without
limitation, in the event that Borrower enters into a transaction whereby assets
are sold outside of the ordinary course of business.

      6.    Conditions to Entering into Amendment.

      The obligation of each Lender to enter into this Agreement and to make
Loans on the date hereof is subject to the satisfaction of the following
conditions precedent, in addition to the conditions precedent set forth in

                  Sale and Purchase of Assets with Hughes, up to $150,000, will

                  acceptable to Lenders, to monitor and/or audit any and all
                  managerial, operational and/or accounting functions of
                  Borrower, including but not limited to analysis of the
                  Borrower's business plans, cash flow forecasts and financial
                  projections, as well as advising the Borrower's management on
                  the preparation and presentation of such information.

            an Event of Default as defined under the Agreement. In such event
            the interest rate shall adjust as provided in the Agreement.
