                                     an event set forth in this paragraph  would
                                     entitle its holder to purchase $50 worth of
                                     Common  Stock (or other  consideration,  as
                                     noted  above)  for $25.  Assuming  that the
                                     Common  Stock had a per share  market value
                                     of $5 at  such  time,  the  holder  of each
                                     valid  Right  would be entitled to purchase
                                     10 shares of Common Stock with a cumulative
                                     value of $50.

Flip-Over:                           If, after an Acquiring  Person  obtains 20%
                                     or more of the Company's  Common Stock, (a)
                                     the Company merges into another entity, (b)
                                     an acquiring entity merges into the Company
                                     or (c) the  Company  sells more than 50% of
                                     the Company's assets or earning power, then
                                     each Right  (other than Rights  owned by an
                                     Acquiring  Person or its  affiliates)  will
                                     entitle the holder thereof to purchase, for
                                     the Exercise  Price,  a number of shares of
                                     Common Stock of the person  engaging in the
                                     transaction  having a then  current  market
                                     value of twice the Exercise Price.

Exchange Provision:                  At any  time  after  the  date on  which an
                                     Acquiring Person obtains 20% or more of the
                                     Company's  Common  Stock  and  prior to the
                                     acquisition by the Acquiring  Person of 50%
                                     of the outstanding  Common Stock, the Board
                                     of  Directors  of the Company may  exchange
                                     the Rights  (other than Rights owned by the
                                     Acquiring  Person  or its  affiliates),  in
                                     whole  or in part,  for  shares  of  Common
                                     Stock of the Company at an  exchange  ratio






                                     of one  share of  Common  Stock  per  Right
                                     (subject to adjustment).

Redemption of the Rights:            Rights will be  redeemable at the Company's
                                     option  for  $0.01 per Right at any time on
                                     or prior to the  tenth  day (or such  later
                                     date as may be  determined by the Company's
                                     Board   of    Directors)    after    public
                                     announcement  that a  Person  has  acquired
                                     beneficial  ownership of 20% or more of the
                                     Company's   Common   Stock   (the   "Shares
                                     Acquisition Date").

Expiration of the Rights:            The  Rights   expire  on  the  earliest  of
                                     September   30,  2003  or   redemption   or
                                     exchange of the Rights as described above.

Amendment of Terms of                The  terms  of the  Rights  and the  Rights
Rights:                              Agreement  may be  amended  in any  respect
                                     without the  consent of the Rights  holders
                                     on  or  prior  to  the  Distribution  Date;
                                     thereafter, the terms of the Rights and the
                                     Rights Agreement may be amended without the
                                     consent of the  Rights  holders in order to
                                     cure  any  ambiguities  or to make  changes
                                     which do not adversely affect the interests
                                     of Rights holders (other than the Acquiring
                                     Person).

Voting Rights:                       Rights will not have any voting rights.

Anti-Dilution Provisions:            Rights  will have the  benefit  of  certain
                                     customary anti-dilution provisions.

Taxes:                               The  Rights   distribution  should  not  be
                                     taxable  for federal  income tax  purposes.
                                     However,  following an event which  renders
                                     the Rights  exercisable or upon  redemption
                                     of the Rights,  shareholders  may recognize
                                     taxable income.
