fact necessary to make such representation or warranty not misleading.

         3.14 SELLERS or MM has  delivered,  to BUYER true and correct copies of
the 10SB and each of its other  reports  to  shareholders  and  filing  with the
Securities and Exchange Commission ("SEC") for the year ended December 31, 1999.

         4.1 At all times prior to the  Closing  Date  during  regular  business
hours, each party will permit the other to examine its books and records and the
books and  records  of its  subsidiaries  and will  furnish  copies  thereof  on

party may provide the other parties with  information  which is  confidential or
proprietary  information.  During the term of this Agreement, and for four years
following the termination of this Agreement,  the recipient of such  information
shall protect such information from disclosure to persons, other than members of
its own or affiliated  organizations and its professional  advisers, in the same
manner as it protects  its own  confidential  or  proprietary  information  from
unauthorized  disclosure,  and  not  use  such  information  to the  competitive
detriment of the disclosing party. In addition,  if this Agreement is terminated

or proprietary information, all copies of all documents or other written records
developed  or  prepared  by such  party  on the  basis of such  confidential  or
proprietary  information.  No information  shall be considered  confidential  or
proprietary if it is (a)  information  already in the possession of the party to
whom  disclosure  is made,  (b)  information  acquired  by the party to whom the
disclosure is made from other sources,  or (c)  information in the public domain
or  generally  available to  interested  persons or which at a later date passes
into the public domain or becomes  available to the party to whom  disclosure is
made without any wrongdoing by the party to whom the disclosure is made.

         4.2  SELLERS  and  BUYER  shall   promptly   provide  each  other  with
information  as to any  significant  developments  in the  performance  of  this
Agreement,  and shall promptly  notify the other if it discovers that any of its
representations,  warranties and covenants contained in this Agreement or in any
document delivered in connection with this Agreement was not true and correct in
all material respects or became untrue or incorrect in any material respect.

         4.3 All parties to this Agreement  shall take all such action as may be
reasonably  necessary and  appropriate and shall use their best efforts in order
to consummate the transactions contemplated hereby as promptly as practicable.

               transactions contemplated hereby;

          (d)  By  any  party,  if  there  is  discovered  any  material  error,

         7.3 The  deposit of $25,000  paid as  consideration  herefore  shall be
non-refundable  if this  transaction  does not close due to the  failure  of the
BUYER to  perform  under the terms and  conditions  of this  Agreement.  If this
transaction  does not close due to the failure of the  SELLERS to perform  under
the terms and  conditions  of this  Agreement  or due to the breach by MM of its
representations  and  warranties  under this  agreement,  the  deposit  shall be
returned to the BUYER.
