Charles  Hansen  (together,  the  "Security  Holders"),  witnesses  that:

     A.     The  Issuer  has  filed  an  application  with  the  Securities
     Administrator  of  the  States  listed  in Schedule A ("Administrators") to
     register certain  of its Equity Securities for sale to public investors who
     are residents of  those  states  ("Registration");

     B.     The Security Holders 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 Security 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, PROMOTIONAL SHARES as
defined  in  the  North American Securities Administrators Association ("NASAA")
Statement  of  Policy  on  Corporate Securities Definitions and all certificates
representing  stock  dividends,  stock  splits, recapitalizations, and the like,
that  are granted to, or received by, the Security Holders while the PROMOTIONAL
SHARES  are  subject  to  this  Agreement  ("Restricted  Securities").

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

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 initially
          share  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, recapitalizations and  the
          like.

<PAGE>
          3.     The  Distribution  may  proceed  on lesser terms and conditions
          than  the terms and conditions stated in paragraphs 1 and 2 above if a
          majority of  the  EQUITY  SECURITIES that are not held by the 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,
     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 a Promoter, which results in a Distribution while this
     Agreement remains in  effect, the Restricted  Shares  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 Securities shall
     remain subject  to  the  terms  of  this  Agreement.

     F.     With the exception of paragraph A.3 above, the Restricted Securities
     shall  have the same voting rights as similar EQUITY SECURITIES not subject
     to this Agreement.

     G.     A  notice  shall  be placed on the face of each stock certificate of
     the  Restricted  Securities  covered by the terms of this Agreement stating
     that the  transfer of the stock evidenced by the certificate  is restricted
     in  accordance  with  the  conditions  set forth on the reverse side of the
     certificate; and

     evidenced  by  the  certificate  is  subject  to  certain  restrictions
     until_________  pursuant  to  an  agreement  between  the  Security  Holder

     file  with the Issuer and the stock transfer agent from  which  a  copy  is
     available  upon  request  and  without  charge.

     I.     The  term  of  this  Agreement  shall  begin  on  the  date that the
     Registration is declared effective by the Administrators ("Effective Date")
     and shall  terminate:

          1.     On  the anniversary of the fourth year from the completion date
          of  the  public  offering;  or

          2.     On  the  date  the  Registration  has  been  terminated  if  no
          securities  were  sold  pursuant  thereto;  or

          3.     If  the  Registration has been terminated, the date that checks

          U.S.  Postal Service with  first  class  postage  affixed;  or
