     4.  Representations  by Investor.  Investor  represents and warrants to the
     Company as follows:

     a) Investor has relied only upon the information presented and contained in
     the Term Sheet  provided  by the  Company  ("Offering  Materials")  and the
     INVESTOR  HAS  READ  AND  UNDERSTANDS  THE  INFORMATION  CONTAINED  IN  THE
     COMPANY'S PROSPECTUS, FORM 10 SB REGISTRATION AND RELATED FILINGS UNDER THE
     SECURITIES ACTS OF 1933 AND 1934,  WHICH ARE AVAILABLE ON THE SEC'S WEBSITE
     REFERRED TO ABOVE. Investor has had the opportunity to ask of the person or
     persons  acting on behalf of the Company any and all relevant  questions in
     connection  with any aspect of the Company  including,  but not limited to,
     the Common Stock offered by the Offering Materials and has received answers
     which  Investor  considers to be reasonably  responsive to such  questions.
     Investor has had the  opportunity to verify the accuracy of the information
     contained in the Offering Materials.

     (b) Investor  understands that Investor is subscribing for the Common Stock
     without  being  furnished any  literature  in connection  with the Offering
     other than the  Offering  Materials,  and that the  Offering  of the Common
     Stock presented in the Offering Materials will not have been scrutinized by
     the Securities and Exchange  Commission or by the securities  administrator
     or  similar  bureau,  agency,  or  department  of the state of  Investor's'
     residence.

     (c) Investor  understands (i) that the Common Stock has not been registered
     under the  Securities  Act of 1933,  as amended  ("Act"),  or registered or
     qualified under the securities laws of the state of Investor's'  residence,
     (ii) REGISTRATION RIGHTS: upon receipt of a written demand by the Investor,
     the  Company  is  obligated  to  register  the  shares of Common  Stock and
     warrants  under the  Securities  Act of 1933, as amended,  within limits of
     current SEC guidelines.

     (d) The Common  Stock is being  purchased  for  Investor's  own account for
     investment  purposes  only and not for the interest of any other person and
     is not  being  purchased  with a view to or for the  resale,  distribution,
     subdivision or fractionalization thereof.

     (e) Investor is able to bear the economic  risks related to purchase of the
     Common Stock for an  indefinite  period of time (i.e.,  Investor is able to
     afford a complete  loss of the Common  Stock  Investor  is  subscribing  to
     purchase).  Investor's  net  worth  and  assets  are  sufficient  to enable
     Investor to purchase shares of Common Stock from Cavit in the amount of the
     Commitment Amount pursuant to this Agreement.

     (f)  Investor's  overall  commitment to  investments  which are not readily
     marketable is not  disproportionate  to Investor's net worth and Investor's
     investment in the Company will not cause such overall  commitment to become
     excessive.

     (g) Investor has adequate means of providing for  Investor's  current needs
     and possible personal contingencies.  Investor has no need for liquidity of
     the Common Stock  subscribed  to be  purchased  hereby and has no reason to
     anticipate any change in Investor's  personal  circumstances,  financial or
     otherwise,  which might cause or require any sale or  distribution  of such
     Common Stock subscribed to be purchased.

     (h) Investor  recognizes  that the purchase of the Common Stock  involves a
     high degree of risk including those special risks.

     (i) Investor understands that Investor's right to transfer the Common Stock
     will be restricted as set forth on the  certificate  evidencing  the Common
     Stock. Such restrictions  include  provisions  against transfer unless such
     transfer is not in violation  of the Act, or  applicable  state  securities
     laws (including investor suitability standards).

                                       2

     (j) All information  which Investor has provided to the Company  including,
     but not  limited  to,  financial  position,  and  status  as an  accredited
     investor,  and knowledge of financial and business matters is true, correct
     and  complete  as of the  date of  execution  of this  Agreement.  Investor
     understands  that the  Company  will  rely in a  material  degree  upon the
     representations contained herein.

     (k)  Investor  understands  that a  legend  may  be  placed  on  any  stock
     certificate  representing  the Common Stock  substantially to the following
     effect:

     On the front side:

     "Transfer of the shares represented by this certificate is restricted - see
     reverse side."

     On the reverse side:

     "The  shares  represented  by this  certificate  have  been  issued  to the
     registered owner in reliance upon written representations that these shares
     have been taken for investment. These shares have not been registered under
     the  Securities  Act of  1933,  as  amended  ("Act"),  and may not be sold,
     transferred or assigned  unless an opinion of counsel  satisfactory  to the
     company  has been  received  by the  company to the effect  that such sale,
     transfer or  assignment  will not be in  violation of the Act and the rules
     and  regulations  promulgated  thereunder  or applicable  state  securities
     laws."

     (l) Investor is an "accredited investor" as defined in Rule 501 promulgated
     under the Act because Investor's  individual net worth (or Investor's joint
     net worth with his spouse) on the date hereof exceeds $1,000,000.

     5.  Securities  Laws.  As a condition  to the  issuance of any Common Stock
pursuant   this   Agreement,   Investor   shall   execute   and   deliver   such
representations,  warranties,  and covenants, that may be required by applicable
federal and state  securities law, or that the Company  determines is reasonably
necessary in connection with the issuance of such Common Stock. In addition, the
certificates  representing  the Common  Stock shall  contain  such  legends,  or
restrictive  legends,  or stop  transfer  instructions,  as shall be required by
applicable Federal or state securities laws, or as shall be reasonably  required
by the Company or its transfer  agent.  The Investor has completed and delivered
an Investor Questionnaire to the Company.

     6.  Binding  Effect.  This  Agreement  shall be  binding  upon the  party's
