      LONG TERM DEBT
     
      Senior
      Convertible Debenture
     
      A
      summary of convertible debentures payable at June 30, 2011
      and December 31, 2010 is as follows:
     
 
      On
      March 4, 2011, the Company sold its Series 5 Power Line
      Carrier product line and related business assets to Dynamic
      Ratings, Inc. (“Dynamic Ratings”).  The
      purchase price was $1,000,000 in cash.  In
      connection with the sale, Dynamic Ratings lent the Company an
      additional $700,000 in the form of a 6% promissory note dated
      March 4, 2011. The Company used the proceeds to retire
      substantially all of its obligations under its $1.6 million
      senior convertible debenture due May 29, 2011 and to cancel
      the related warrants covering 11.7 million shares of the
      Company’s common stock.  In exchange for the
      early retirement of debt and cancellation of warrants, the
      Company provided the lender with an unsecured one-year
      promissory note for $50,000 (Promissory Note#2).
     
      Business
      Loan
     
      On
      September 11, 2009, the Company entered into a Loan
      Agreement in the aggregate principal amount of $300,000 with
      the Wisconsin Department of Commerce (the
      “Department”).  The outstanding
      principal balance bears interest at the annual rate of two
      (2.00) percent. Payment of interest and principal is to be
      made in the following manner:   (a) payment of
      any and all interest that accrues from the date of
      disbursement commenced on January 1, 2010 and continued on
      the first day of each consecutive month thereafter through
      and including December 31, 2010; (b) commencing on January 1,
      2011 and continuing on the first day of each consecutive
      month thereafter through and including November 1, 2016, the
      Company shall pay equal monthly installments of $4,426 each;
      followed by a final installment on December 1, 2016 which
      shall include all remaining principal, accrued interest and
      other amounts owed by the Company to the Department under the
      Loan Agreement.  The Company may prepay amounts
      outstanding under the credit facility in whole or in part at
      any time without penalty.  The credit facility is
      secured by substantially
      all of the Company’s assets and the proceeds
      from this loan were used for the working capital requirements
      of the Company.  The outstanding borrowing under
      the agreement at June 30, 2011 was $276,346.
     
      Promissory
      Note #1
     
      On
      March 4, 2011, the Company sold all its Series 5 PLC product
      line assets to Wisconsin-based Dynamic Ratings, Inc.
      (“Purchaser”) under an Asset Purchase Agreement
      (“APA”).  Per the APA, the Company
      signed a Promissory Note
      (“Note #1”) due to Purchaser in the aggregate
      principal amount of $700,000. The outstanding principal balance
      bears interest at the annual rate of six (6) percent and is
      due on March 31, 2014.   Note #1 may be
      prepaid in whole or in part, without penalty at any time,
      however scheduled payments are due on June 30, 2012 and June
      30, 2013.  Payments shall be applied first to
      accrued but unpaid interest and then to
      principal.  Note #1
      contains certain earn-out provisions that encompass both the
      Company’s and Purchaser’s revenue
      volumes.  Provided these provisions are met, the
      Company could potentially retire Note #1 prior to its
      expiration date.  Payments
      not made when due, by maturity acceleration or otherwise,
      shall bear interest at the rate of 12% per annum
      from the
      date due
      until fully paid
     Promissory Note #2 
      From
      the sale of its Series 5 PLC product line assets, the Company
      used the proceeds received to retire substantially all of its
      obligations under its $1.6 million senior convertible
      debenture due May 29, 2011 and to cancel the related warrants
      covering 11.7 million shares of the Company’s common
      stock.  In exchange for the early retirement of
      debt and cancellation of warrants, the Company provided the
      lender with an unsecured one-year promissory note
      (“Note #2”) for $50,000.  The outstanding principal balance
      bears interest at the annual rate of five and one-quarter
      (5.25) percent and is due on March 4, 2012. The monthly
      payment of principal and interest is
      $4,385.  However Note #2 is due immediately if the
      Company (a) receives three million ($3,000,000) dollars in
      aggregate in new debt or equity financing, (b) attains one
      million ($1,000,000) dollars in EBITDA for any reporting
      quarter or (3) becomes insolvent.  The Note may be
      prepaid in whole or in part, without penalty at any
      time.  Payments shall be applied first to accrued
      but unpaid interest and then to
      principal.
