each  Selling  Stockholder,  at the Closing (as defined  below),  the PC Mailbox

each Selling  Stockholder a pro rata share of the Company Shares,  as determined

     number of PC Mailbox Shares owned by the Selling Stockholder at the Closing
     and the  denominator  of which is the  total  number of PC  Mailbox  Shares
     issued and outstanding at the Closing (i.e., 50,000,000).

                  1.2      Instruments of Transfer.

          (a) PC Mailbox Shares.  Each Selling  Stockholder shall deliver to the

     interest  in and to the PC  Mailbox  Shares.  From  time to time  after the
     Closing Date, and without further  consideration,  the Selling Stockholders
     will execute and deliver such other  instruments  of transfer and take such
     other actions as the Company may reasonably  request in order to facilitate
     the transfer to the Company of the  securities  intended to be  transferred
     hereunder.

          (b) The  Company  Shares.  The  Company  shall  deliver to the Selling
     Stockholders  on the Closing  Date  original  certificates  evidencing  the
     Company Shares or in the  alternative  an authorized  Treasury Order to the
     Company's  Transfer Agent for the same, in form and substance  satisfactory
     to the Selling  Stockholders,  in order to effectively  vest in the Selling
     Stockholders  all right,  title and interest in and to the Company  Shares.
     From  time  to  time  after  the  Closing   Date,   and   without   further
     consideration,  the Company will execute and deliver such other instruments
     and take such other  actions as the  Selling  Stockholders  may  reasonably
     request in order to facilitate the issuance to them of the Company Shares.

     1.3 Closing.  The closing  ("Closing")  of the exchange of the Viper Shares
and the Company  Shares  shall take place at the offices of Viper at 10:00 a.m.,

individual  power and  authority to enter into and to carry out all of the terms
of this Agreement and all other  documents  executed and delivered in connection
herewith (collectively,  the "Documents").  All individual action on the part of

performance  of the Documents by the Selling  Stockholder  has been taken and no
further  authorization  on the part of the  Selling  Stockholder  is required to
consummate the  transactions  provided for in the  Documents.  When executed and
delivered by the Selling  Stockholder,  the Documents shall constitute the valid
and  legally  binding  obligation  of the  Selling  Stockholder  enforceable  in
accordance  with  their  respective  terms,  except  as  limited  by  applicable
bankruptcy,  insolvency  reorganization  and  moratorium  laws  and  other  laws
affecting  enforcement of creditor's rights generally and by general  principles
of equity.

amended  ("Act"),  or under any state  securities  law. The Selling  Stockholder
understands  that the  Company  Shares  will be  characterized  as  "restricted"
securities under federal  securities laws inasmuch as they are being acquired in
a  transaction  not  involving  a public  offering  and that under such laws and
applicable  regulations such securities may be resold without registration under
the Act only in certain limited  circumstances.  The Selling  Stockholder agrees
that the  Selling  Stockholder  will not sell all or any  portion of the Company
Shares except pursuant to registration under the Act or pursuant to an available
exemption from registration under the Act. The Selling  Stockholder  understands
and  acknowledges  that all  certificates  representing the Company Shares shall

shall  refuse to transfer  the Company  Shares  except in  accordance  with such
restrictions:

"THE SHARES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES  ACT OF  1933,  AS  AMENDED  (THE  "ACT"),  OR  UNDER  CERTAIN  STATE
SECURITIES  LAWS. NO SALE OR TRANSFER OF THESE SHARES MAY BE MADE IN THE ABSENCE

validity  of this  Agreement  or any  part  hereof  or the  right  of any  party
