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

1.   Acknowledgement of Indebtedness.

     (a) Borrower hereby reaffirms that as of June 4, 2002, Borrower is indebted
         to Lender  pursuant  to the Loan  Documents  in the amount of
         $4,213,300  which includes (i) $3,455,254 Principal and (ii) $758,046
         in past accrued interest.

     (b) As used in this  Agreement,  Borrower's  "Indebtedness"  to the  Lender
         shall mean the sums  referred to above in Section  1(a)  hereof as such
         amounts shall continue to accrue,  plus Lender's  reasonable costs and
         expenses incurred in  collection  of any and all of the  Indebtedness
         from the  Borrower  and the reasonable costs incurred in the
         negotiation of this Agreement and the ancillary agreements,  documents
         and enforcement  devices provided for herein,  including, but not
         limited to, costs of collection thereof.

     (c) All payments hereunder for application to the Indebtedness shall be
         made, without setoff, counterclaim or withholdings of any kind
         whatsoever.

     (d) Borrower acknowledges that it is in default under, inter alia
         (collectively, the "Events of Default"):

         (i) Sections 4 of the Note;

         (ii)Section 6.3 of the Loan Agreement; and

         (iii)Section 7.1(g) of the Loan Agreement.

2.   Foreclosure on Collateral; Agreements of Lender.

     (a)  By reason of the occurrence and continuation of the Events of Default,
          the Lender has notified the Borrower (the "Foreclosure Notice") of the
          Lender's intention to exercise its rights as a secured creditor and
          foreclose on some or all of the Collateral (the "Foreclosure").

     (b)  The Borrower and Lender have engaged in negotiations with respect to
          the intended Foreclosure and Borrower has agreed to deliver, and
          Lender has agreed to accept legal title to the Vidikron Shares in
          partial satisfaction of the Indebtedness, subject to consummation of
          the other agreements and transactions contemplated by this Agreement.
          The Borrower covenants and agrees to deliver to the Lender legal and
          beneficial title and interest in and to the Vidikron Shares. Delivery
          of such legal and beneficial title in and to the Vidikron Shares shall
          be in partial satisfaction of $50,000.00 of the aggregate Indebtedness
          owed to the Lender (the "Debt Reduction").  Borrower hereby waives its
          right to notice of default, acceleration and Lender's intent to
          foreclose on the Vidikron Shares and the disposition thereof, whether
          pursuant to the Uniform Commercial Code or otherwise, and consents
          thereto.

     (c)  The parties hereto acknowledge that the Debt Reduction has been
          calculated based on the facts that Vidikron is insolvent and perceived
          to be of no value.
<PAGE>

     (d)  Lender agrees to defer the Foreclosure on the remaining Collateral, to
          wit, Markland Collateral and the Vidikron Collateral.

3.   Restructure of Lender's Indebtedness Balance.

     The balance of the Indebtedness to the Lender will be evidenced by
     Borrower's execution of an amended secured convertible revolving credit
     note of up to $4.5 million in the form annexed hereto (the "Amended Note").
     The initial indebtedness outstanding on the Amended Note shall be credited
     to the extent of the Debt Reduction for an initial net outstanding balance
     of $4,163,300 (the "Indebtedness Balance"). The Amended Note shall provide,
     inter alia, as follows:

     (a) the annual  interest  rate  accruing  on the  Amended  Note from and
         after the  Foreclosure  Date shall be reduced to six (6%)percent per
         annum;

     (b) the maturity date of the Amended Note shall be extended to December 31,
         2002;

     (c) Lender  shall  retain  its  liens on the  Technologies  Collateral  and
         the  Vidikron  Collateral  to  secure  payment  of the Indebtedness
         Balance represented by the Amended Note; and

     (d) Lender shall have conversion rights with respect to the common stock of
         Borrower based on a conversion rate of 80% of the closing bid price for
         Borrower's common stock on the average of five (5) trading days
         immediately preceding conversion.

4.   Additional Agreements and Acknowledgements.

     (a) By execution and delivery of this Agreement, Borrower hereby
     acknowledges, confirms and reaffirms that the full amount of the
     Indebtedness and its obligations in respect thereof are currently due and
     payable and Borrower has no claim, defense, setoff or counterclaim against
     the Lender or any of its officers, directors, employees, affiliates, agents
     or attorneys with respect to such amounts. In addition, Borrower hereby
     acknowledges that the Loan Documents are in full force and effect and there
     are no oral agreements or understandings that modify or alter the terms
     thereof.  Nothing contained in this Agreement shall constitute a waiver of,
     or affect the enforceability of, any other Document. Borrower hereby
     expressly waives any right to notice of sale or any right to a public sale
     under the Uniform Commercial Code, as in effect in New York.

     (b) Lender reserves any and all rights and remedies it may have against the
     Borrower and any and all Collateral provided by the Loan Documents or
     hereby. Nothing contained in this Agreement shall constitute a limitation
     upon or waiver of such rights and remedies available to Lender under the
     terms of the Loan Documents nor shall anything contained herein absolve the
     Borrower from any liability arising pursuant to the terms of the Loan
     Documents and the Note, as amended pursuant to this Agreement and the
     Amended Note from and after the Foreclosure date.

     (c)Borrower agrees to pay on demand all reasonable fees and expenses
     incurred by Lender (including, without limitation, the fees and

     preparation, execution, delivery, enforcement, maintenance, and amendment
     of this Agreement and the documents and instruments referred to herein,
     including, without limitation, the fees and expenses incurred by Lender
     (including, without limitation, the reasonable fees and disbursements of
     counsel) in connection with any waiver or consent to the Loan Documents,
     and in connection with any restructuring of the Loan Documents, and
     enforcement thereof and collection and credit administration thereunder.

  (b)Relief from Automatic Stay in Bankruptcy. Borrower and Vidikron knowingly,
     voluntarily, intentionally agree with Lender that notwithstanding anything

     provisions of applicable law. Lender only shall be required to file a
     motion for relief from the automatic stay provisions of 11 U.S.C. ss. 362
     and Borrower and Vidikron hereby consent to an emergency hearing thereon.
     Borrower and Vidikron hereby waive the right to oppose the motion or assert
     any defense to the relief requested by Lender. Lender is authorized to
     submit an affidavit with the motion (a) in identifying the existing
     defaults and any Events of Default hereunder or under the other Loan
     Documents, (b) stating the amount of the Obligations and (c) advising the
     bankruptcy court of Borrower's and Vidikron's consent to unconditional
     relief from the automatic stay.

 (ii)Borrower and Vidikron shall not without Lender's written consent, seek to
     obtain financing under 11 U.S.C. ss. 364 that will result in the granting
     of liens and security interests in the Pledged Collateral and Collateral
     with priority over Lender's liens and security interests.

(iii)Lender's entitlement as aforesaid to the lifting of the automatic stay
     hereunder by the appropriate bankruptcy court shall be deemed "for cause"
     pursuant to ss. 362(d)(1) of the Bankruptcy Code as amended from time to
     time.

  (c)UCC Waivers.

   (i)Borrower and Vidikron will not, directly or indirectly, do any act or fail
     to do any act, which would impair or affect Lender's security interest in
     any collateral heretofore provided to Lender, nor will Borrower or
     Vidikron, upon any default or Event of Default under this Agreement or the
     other Loan Documents, contest Lender's right to obtain judgment against
     Borrower or to foreclose upon any collateral pledged to Lender, nor will
     Borrower move to vacate or enjoin such judgment or foreclosure.

  (ii)Borrower and Vidikron each waives and renounces all rights which are
     waivable under Article 9 of the UCC, whether such rights are waivable
     before or after default, including, without limitation, those rights with

     and any right to notice relating to disposition of collateral.

(d) No Waiver.

    No failure on the part of Lender to exercise, and no delay in
    exercising, any right hereunder shall preclude any other or
    further exercise thereof or the exercise of any other right.
    The remedies herein provided are cumulative and not exclusive
    of any provided by law.

    counterparts, taken together, shall constitute but one and the
    same Agreement.

(g) Binding Effect.
