"Brown Simpson").

         WHEREAS,  the  Company  and  Brown  Simpson  are  parties  to  (i)  the
Securities  Purchase  Agreement  dated as of November 23, 1998 and amended as of
December 2, 1998 and (ii) the Securities  Purchase Agreement dated March 3, 1999
(the "March 3rd Agreement"  and,  together with the November 23, 1998 Securities
Purchase Agreement, as amended, the "Securities Purchase Agreements");

         WHEREAS,  the  Company  has failed to have the  Registration  Statement
covering the  Registrable  Securities  declared  effective by the Securities and
Exchange  Commission  (as such  terms are  defined  in the  Registration  Rights
Agreement  (the  "Registration  Rights  Agreement")  among the Company and Brown
Simpson,  dated as of November  23,  1998) in  accordance  with the terms of the
Registration Rights Agreement;

         WHEREAS,  pursuant to terms of the warrants (the "Warrants")  issued to
Brown Simpson in connection with the Securities Purchase Agreements, the Company
has the right to cause  Brown  Simpson  to  exercise  the  Warrants  (the  "Call
Option") if, with respect to each series of Warrants, the Per Share Market Value
(as defined in the  Warrants)  equals or exceeds the amounts set forth under the
column  entitled  "Call Option  Price" on Schedule I hereof for the  consecutive
number of trading  days set forth under the column  entitled  "Trading  Days" on
Schedule I hereof;

         WHEREAS,  pursuant to terms of the March 3rd Agreement, the Company has
the right to cause Brown  Simpson to purchase  the Trance D Units (as defined in
the  March  3rd  Agreement)  if  certain  conditions  set forth in the March 3rd
Agreement are met (the "Tranche D Option");

         WHEREAS,  the  Company  and Brown  Simpson  desire to (i)  suspend  all
penalties  incurred by the Company through August 2, 1999 in connection with the
Registration  Rights  Agreement,  (ii)  amend,  with  respect to each  series of
Warrants,  the number of  consecutive  trading days which triggers the Company's
Call Option to the number of consecutive trading days set forth under the column
entitled  "Trading  Days" on  Schedule  II hereof and (iii)  amend the number of
consecutive trading days which triggers the Company's Tranche D Option.

         NOW THEREFORE,  in  consideration  of the mutual  agreements  contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto, intending to be legally bound
hereby, agree as follows:

1.       Unless  otherwise  expressly  stated  herein to the  contrary,  all the
provisions  of the  Securities  Purchase  Agreements,  the  Registration  Rights
Agreement and the Warrants  remain valid,  binding and in effect as set forth in

<PAGE>

the Securities  Purchase  Agreements,  the Registration Rights Agreement and the
Warrants,  respectively,  except as  necessary  to give  effect  to the  matters
provided for in this Agreement.

2. Brown Simpson  shall waive any penalties  incurred by the Company and owed to
Brown Simpson  through August 2, 1999 which relate to the failure of the Company
to have a Registration  Statement covering the Registrable  Securities  declared
effective by the Securities and Exchange Commission in accordance with the terms
of the Registration Rights Agreement.

3. The  Company  shall,  with  respect  to each  series of  Warrants,  amend the
applicable  number of  consecutive  trading  days for which the Per Share Market
Value is required to equal or exceed the "Call Option Price"  before  triggering
the Company's  Call Option to the number of  consecutive  trading days set forth
under the column entitled "Trading Days" on Schedule II hereof.

4.       Section  4.2(b)(xvi)  of the March 3rd  Agreement  shall be  amended as
follows:

         Common  Stock  Price.  The Per Share  Market  Value of the Common Stock
         shall have been more than the Tranche D Purchase Price per share for at
         least 130 consecutive  trading days prior to the Tranche D Closing Date
         and at least  equal to the  Tranche D Purchase  Price on the day before
         the Tranche D Closing Date; provided,  however,  that in no event shall
         the  Tranche  D  Closing  occur  on a date  which  is prior to the 16th
         calendar day of the month  following such 130  consecutive  trading day
         period.  The "Per Share Market Value" means on any particular  date the
         closing bid price per share of the Common  Stock on such date on Nasdaq
         or other  registered  national stock exchange on which the Common Stock
         is then  listed  or if there is no such  price on such  date,  then the
         closing  bid price on such  exchange  or  quotation  system on the date
         nearest preceding such date; and"

5. Notwithstanding the foregoing, if the Securities and Exchange Commission does
not  declare  the  Registration  Statement  effective  by  August 2,  1999,  the
penalties owed by the Company to Brown Simpson with respect to the  Registration
Rights  Agreement shall be reinstated and owed in full to Brown Simpson from the
date on which such penalties first began to accrue, as though this Agreement had
not been entered into; provided,  however, that in the event the foregoing shall
occur  (i) the  number of  trading  days set forth  under  the  column  entitled
"Trading  Days" on  Schedule  II hereof  shall  continue to remain in effect and
shall not revert  back to the number of trading  days set forth under the column
entitled "Trading Days" on Schedule I hereof and (ii) Section 4.2(b)(xvi) of the
March 3rd Agreement  shall remain in effect as amended  pursuant to the terms of
this Agreement.
