9.       Redemption.  Notwithstanding  anything to the contrary  herein,  in the
event  that  any  one or  more  of the  following  occur  (each,  a  "Redemption
Trigger"), the Rights Holder, at its option, may require the COMPANY to effect a
Warrant  Redemption  (as  defined  below) of any or all (at the Rights  Holders'
option) of the Rights Holders' Warrants (as defined below):

         A.     The  COMPANY  merges  into or is bought out by another  company,
         or becomes a private  company that does not have publicly traded common
         stock, or sells all or substantially all of the COMPANY's assets, or
         B.     Common  stock of the COMPANY is tendered, purchased or exchanged
         pursuant to a tender offer, purchase offer or exchange offer, or
         C.     There is a Change of Control (as defined below) of the COMPANY's
         board of directors, and one or more of the following occurs:

                (1) COMPANY  sells,  conveys,  disposes of, spins off or assigns
                any or all of its NEWCO  Stock,  or any or all of its  rights to
                receive  the  NEWCO  Income,  to any third  party,  in each case
                without the Right Holder's written consent.
                (2) The  COMPANY  issues  or  sells,  or agrees to issue or sell
                Variable  Equity  Securities  (as  defined  below),  for cash in
                private  capital  raising  transactions or any securities of the
                Company  pursuant to an equity line  structure or format without
                obtaining the prior written approval of the Rights Holder,  with
                the  exception of any such  agreements,  transactions  or equity
                lines existing as of the date hereof.  For purposes hereof,  the
                following  shall be  collectively  referred  to herein  as,  the
                "Variable Equity Securities":  any debt or equity securities (or
                securities  pursuant  to an equity  line  structure  or  similar
                structure)   which  are   convertible   into,   exercisable   or
                exchangeable  for,  or carry  the  right to  receive  additional
                shares of Common Stock either (i) at any conversion, exercise or
                exchange  rate or other price that is based upon  and/or  varies
                with the trading prices of or quotations for Common Stock at any
                time after the initial issuance of such debt or equity security,
                or (ii) with a fixed conversion, exercise or exchange price that
                greater  than a  thirty  percent  (30%)  discount  to  the  then
                prevailing  market or is subject to being  reset at some  future
                date at any time  after  the  initial  issuance  of such debt or
                equity  security  due to a  change  in the  market  price of the
                Company's Common Stock since date of initial issuance.

         If a Redemption  Trigger has occurred  and the Rights  Holder  elects a
redemption,  then any of the Rights  Holders'  Warrants  selected  by the Rights
Holder for such  redemption  shall be  redeemed  ("Warrant  Redemption")  by the
Company as of the record date for such  Redemption  Trigger at a price per share
(that is, per share of common stock represented by the warrants) for each Rights
Holder  Warrant equal to the  "Redemption  Price," which shall be defined as the
greater of (A) $0.50 per share,  less the Exercise Price per share in effect for
that Rights Holder Warrant on the trading day  immediately  preceding the record
date of the  Redemption  Trigger  (each subject to adjustment to account for any
forward or reverse  stock  splits),  or (B) the  applicable  Warrant  Redemption
Market Value (as defined below).  For purposes hereof,  the "Warrant  Redemption
Market Value" shall equal the aggregate of the highest Warrant Market Values (as
defined  below)  for  all of the  Right  Holders'  Warrants  being  so  redeemed
calculated  on any date during the thirty (30) business day period ending on the
record date for the Redemption Trigger.

                                       3


         For purposes hereof,

         "Change  in  Control"  shall  mean  any  change  in the  makeup  of the
COMPANY's  board of directors  such that the  remaining  board  members from the
following group do not constitute a majority of the board: Gloria Felcyn,  David
Pohl, Helmet Faulk, Lowell Giffhorn and Carlton Johnson, Jr.

         "Rights  Holders'  Warrants" shall mean all warrants to purchase common
stock that have been issued from the Company to the Rights Holder for any reason
at any time in the past up through the date hereof.

          "Warrant  Market Value" shall equal the number of shares that would be
issuable in a "cashless  exercise" on the date in  question,  under the terms of
the  warrant   (without  regard  to  any   contractual,   legal,  or  regulatory
restrictions  on such  exercise  and  issuance,  if any,  and without  regard to
whether or not a  sufficient  number of shares are  authorized  and  reserved to
effect any such exercise and  issuance),  multiplied by the Closing Price of the
Company's common stock for the preceding trading day.

          "Closing  Price" shall mean the closing  price on the O.T.C.  Bulletin
Board, Nasdaq Small Cap Market, the National Market System ("NMS"), the New York
Stock  Exchange,  or if no longer  traded on the Nasdaq  Small Cap  Market,  the
National  Market  System  ("NMS"),  the New York Stock  Exchange,  or the O.T.C.
Bulletin  Board,  the "Closing  Bid Price" shall equal the closing  price on the
principal national securities exchange or the  over-the-counter  system on which
the Common  Stock is so traded and, if not  available,  the mean of the high and
low prices on the  principal  national  securities  exchange or other  market on
which the Common Stock is so traded.
