this Agreement,  on each Closing Date, (i) the Escrow Agent shall,  upon receipt
of funds fro the Buyer(s) deliver to the Company in accordance with the terms of
the Escrow Agreement such aggregate proceeds for the Series E Preferred Stock to

(3) calendar days prior written  notice to the Buyer(s),  all or any part of the
Series E Preferred  Stock at a redemption  price of one hundred  twenty  percent
(120%) of the amount redeemed.  The redemption  price, in immediately  available
funds, shall accompany the written notice. The redemption shall not apply to any
Series E Preferred Stock that is the subject of a pending Conversion Notice.

(e)  Warrants.  The Buyer(s)  shall  receive a warrant to purchase  seventy five
thousand  (75,000)  shares of Common Stock of the Company (the  "Warrant").  The
Warrant shall be exercisable on a "cash basis" and have an exercise price of one

its principal  exchange or market, as quoted by Bloomberg,  LP, for the ten (10)
trading days  immediately  preceding  conversion.  Such Series E Preferred Stock
shall  automatically  convert into shares of the  Company's  Common Stock at the
lower of either conversion price described above on the second (2nd) anniversary
of the date hereof. In the event a Buyer effectuates a partial conversion of the
Series E Preferred Stock the Company shall promptly,  but in no event later than
five (5) business day from the date of conversion, issue to the Buyer a Series E
Preferred Stock certificate reflecting the Series E Preferred Stock owned by the
Buyer minus the converted amount.

(g) Limitation on Conversion.  In no event shall a Buyer effectuate a conversion
of the Series E Preferred  Stock which shall cause the Buyer to own in excess of
nineteen and 9/10 percent  (19.9%) of the then  outstanding  Common Stock of the
Company  immediately  prior  the  Closing  Dates  without  the  approval  of the
shareholders  of the Company in accordance  with the rules of the American Stock
Exchange  (the  "AMEX").  In the  event  that  the  conversion  of the  Series E
Preferred Stock would result in the issuance of more than 19.9% of the Company's
outstanding Common Stock, then only such portion of the Series E Preferred Stock
that can be converted  without  violating the forgoing  limit shall be converted
and the Buyer(s) shall retain the unconverted portion. The Company shall, within
60 days of such event, seek shareholder approval to issue such additional Common
Stock as may be required to honor the  conversion.  If the  shareholders  do not
approve such  issuance or the Company  fails to seek such  approval  within such
time frame, the Company shall be obligated to redeem the unconverted  portion of
the Series E Preferred  Stock at the redemption  price described in Section 1(d)
hereof.
