residents of those states ("Registration");

                  B. The Security Holders listed on Schedule B are the owners of
the shares of common  stock or similar  securities  and/or  possess  convertible
securities,  warrants,  options  or  rights  which  may be  converted  into,  or
exercised to purchase shares of common stock or similar securities of Issuer.

                  C.       As a condition to Registration, the Issuer and Secu-
rity Holders ("Signatories") agree to be bound by the terms of this Agreement.

         II.  THEREFORE,  the  Security  Holders  agree  not  to  sell,  pledge,
hypothecate,  assign, grant any option for the sale of, or otherwise transfer or
dispose  of,  whether  or  not  for   consideration,   directly  or  indirectly,

("Restricted Securities").

                  Beginning  one year  from the  completion  date of the  public
offering,  two and one-half percent (2 1/2%) of the Restricted Securities may be
released  each  quarter  pro rata  among the  Security  Holders.  All  remaining
Restricted  Securities  shall be released from escrow on the  anniversary of the

         III.     THEREFORE, the Signatories agree and will cause the following:

         A.       In  the   event  of  a   dissolution,   liquidation,   merger,
                  consolidation,   reorganization,   sale  or  exchange  of  the
                  Issuer's  assets  or  securities  (including  by way of tender
                  offer),  or any other  transaction or proceeding with a person
                  who is not a Promoter,  which results in the  distribution  of
                  the Issuer's assets or securities ("Distribution"), while this
                  Agreement remains in effect that::

                  1.       All holders of the Issuer's EQUITY SECURITIES will

                                       33

                  on a pro  rata,  per  share  basis  in  the  Distribution,  in
                  proportion to the amount of cash or other  consideration  that
                  they paid per share for their EQUITY SECURITIES (provided that
                  the   Administrator  has  accepted  the  value  of  the  other
                  consideration),  until  the  shareholders  who  purchased  the
                  Issuer's  EQUITY  SECURITIES  pursuant to the public  offering
                  ("Public Shareholders") have received, or have had irrevocably
                  set  aside for them,  an amount  that is equal to one  hundred
                  percent (100%) of the public  offering's price per share times
                  the number of shares of EQUITY  SECURITIES that they purchased
                  pursuant to the public  offering  and which they still hold at
                  the time of the Distribution, adjusted for stock splits, stock
                  dividends, recapitalizations and the like; and

                  2.  All  holders  of  the  Issuer's  EQUITY  SECURITIES  shall
                  thereafter  participate on an equal, per share basis times the
                  number of shares of EQUITY SECURITIES they hold at the time of
                  the Distribution, adjusted for stock splits, stock dividends,
                  recapitalization and the like.

                  3.       The Distribution may proceed on lesser terms and con-
                  ditions than the terms and conditions stated in paragraphs 1
                  and 2 above if a majority of the EQUITY  SECURITIES  that  are
                  not  held by  Security  Holders, officers,  directors,  or
                  Promoters  of the Issuer,  or their associates  or  affiliates
                  vote,  or  consent  by  consent procedure, to approve the
                  lesser terms and conditions.

         B.       In  the   event  of  a   dissolution,   liquidation,   merger,
                  consolidation,  reorgani-  zation,  sale  or  exchange  of the
                  Issuer's  assets  or  securities  (including  by way of tender
                  offer),  or any other  transaction or proceeding with a person
                  who is a Promoter,  which results in a Distribution while this
                  Agreement remains in effect,  the Restricted  Securities shall
                  remain subject to the terms of this Agreement.

         C.       Restricted Securities may be transferred by will, the laws of
                  descent and distribution, the operation of law, or by order of
                  any court of competent jurisdiction and proper venue.

         D.       Restricted  Securities  of a deceased  Security  Holder may be
                  hypothecated  to pay the  expenses  of the  deceased  Security
                  Holder's estate. The hypothecated  Restricted Securities shall
                  remain  subject  to the  terms of this  Agreement.  Restricted
                  Securities may not be pledged to secure any other debt.

         E.       Restricted  Securities  may  be  transferred  by  gift  to the
                  Security Holder's family members, provided that the Restricted
