acquired such formulations from Petra Bonita. Accordingly, the parties agree
that the Asset Acquisition shall hereby be rescinded effective as of the date
hereof. The transaction shall hereinafter be deemed null and void in all
respects, as if such transaction shall never have occurred.

and (ii) will have good and marketable title to the Assets, free and

clear of all claims, encumbrances, security interests or liens of any kind of
nature whatsoever, except as to any claims, encumbrances, security interests or
liens existing upon the transfer of the Assets from Petra Bonita to the Company.

              3. Petra Bonita hereby tenders the Petra Bonita Shares to the
Company. Petra Bonita hereby warrants and represents, upon which warranties and
representations the Company relies, that upon delivery of the Petra Bonita
Shares from Petra Bonita: (i) the Company will be the lawful owner, of record

thereto; and (ii) there are no agreements or understandings between Petra Bonita
and any other person, firm, corporation, or other entity respecting the voting
of any of the Petra Bonita Shares.
