                                    ---------

     NOW,  THEREFORE,  for good and valuable consideration, the receipt of which
is  hereby  acknowledged,  the  parties  agree  as  follows:

          1.     Sale  and  Issuance of Shares.  In consideration for Investor's
                 -----------------------------
     consideration  and covenants set forth herein, Lenz shall issue to Investor
     Janice Margaret Wilby, Twenty Five Thousand (25,000) shares of common stock
     of  Lenz (the "Shares") on, or before, the Issuance Date as defined herein.

     non-assessable. Payment for the Shares shall be $2.00 per share for a total
     price  of $50,000.00. Such payment shall be made upon the execution of this
     Agreement.

          2.     Investor  Representations  and  Warranties.  In order to induce
                 ------------------------------------------
     Lenz  to  accept this Agreement, Investor hereby represents and warrants to
     Lenz  as  follows:

          (a)     Investor  Intent.  The Investor is acquiring the Shares herein
                  ----------------
subscribed solely for her own account as principal, for investment purposes only
and  not with a view to the resale or distribution thereof, in whole or in part,
and  the  Investor  will  hold  the  Shares  as  an  investment.

          (b)     Accredited  Investor.  Investor  has  the financial ability to
                  --------------------
bear the economic risk of an investment in Lenz, has adequate means of providing
for  her  current needs and personal contingencies, has no need for liquidity in
such  investment  and  could  afford  a  complete loss of such investment.  With
respect  to the investment made under this Agreement, Investor is an "Accredited
Investor"  as  such  term  is  defined  in  Regulation D promulgated by the Act.
Investor  understands  that  the  categories  included  within the definition of
"Accredited  Investor" which pertain to natural persons are as follows:  (i) any
natural person whose individual net worth, or joint net worth with that person's
spouse,  at  the  time of her purchase, exceeds One Million Dollars ($1,000,000)
and  (ii)  any  natural  person  who  had  an individual income in excess of Two
Hundred  Thousand  Dollars  ($200,000)  in  each of the two most recent years or
joint  income  with  that  person's  spouse  in excess of Three Hundred Thousand
Dollars  ($300,000)  in  each of those years and has a reasonable expectation of
reaching  the  same  income  level  in  the  current  year.

          (c)     Opportunity  to  Investigate.  Investor  or  her  Investment
                  ----------------------------
Advisor  (if  any)  has been given a full opportunity to ask questions of and to
receive answers from the officers, agents and representatives of Lenz concerning
the  terms  and  conditions  of  this  Agreement and the business of Lenz and to
obtain  such  other  information that the Investor or her Investment Advisor (if
any)  desires in order to evaluate an investment in Lenz, and all such questions
have  been  answered  to  the  full  satisfaction  of  the  Investor.  Investor
acknowledges that the Investor or the Investor's Investment Advisor (if any) has
had  access  to the same kind of information concerning Lenz that is required by
Schedule  A  of  the  Act  to  the  extent that Lenz possesses such information.

          (d)     Reviewed  Merits  With  Investments  Advisor.  Investor  has
                  --------------------------------------------
reviewed  the  merits of an investment in Lenz with tax and legal counsel and an
investment  advisor  to  the  extent  deemed  advisable  by  Investor.

          (e)     Acknowledgment  of  Risks.  Investor  acknowledges  and
                  -------------------------
understands  that  (i)  Lenz  is  in  a  very  competitive field, and expects to
encounter  competition  from  other  companies  which  have  substantially  more
resources and experience, and are better known, than Lenz; (ii) Lenz's future is
dependent upon its acceptance in the marketplace, and there can be no assurances
that  acceptance will be achieved; (iii) although Lenz cannot accurately predict
its future operating results, it will incur losses from operations subsequent to
the  date  hereof  and  extending  into an indeterminable time in the future and
there  can  be  no  assurances that it will ever achieve profitability; (iv) the
aggregate  number  of  capital  shares  sold by Lenz, from time to time, and the
price  at  which  such  shares  are  sold,  will  be  determined by the Board of
Directors  of Lenz, in its discretion, giving consideration to the needs of Lenz
to  obtain  financing,  and  there  can be no assurances that Lenz will not sell
capital  shares  in the future at a lower per-share price; (v) Lenz will require
additional  financing  in  the  future, has no commitments for such financing at
this  time  and no assurances can be given that Lenz will be able to obtain such
financing,  on terms acceptable to Lenz, at the time it is required, and (vi) in
purchasing  the  Shares,  Investor  is  making  a highly speculative investment.


<PAGE>
          (f)     Shares  Not  Registered.  Investor understands that the Shares
                  -----------------------
have  not  been  registered  under  the  Act,  or the securities laws of certain
states,  in  reliance upon specific exemptions from registration thereunder, and
he  agrees  that  her  Shares  may  not  be sold, offered for sale, transferred,
pledged, hypothecated or otherwise disposed of except pursuant to a registration
in  compliance  with  the  Act and applicable state securities laws, pursuant to
Rule 144 promulgated under the Act and similar provisions under applicable state
securities  laws,  or  pursuant  to  an  exemption  from  registration.

          (g)     No Federal or State Endorsement.  Investor understands that no
                  -------------------------------
federal or state agency has made any finding or determination as to the fairness
of  an  investment  in,  or  any  recommendation  or endorsement of, the Shares.

          (h)     Additional Financing.  The Investor understands that Lenz will
                  --------------------
require  additional  financing  in  the figure, that Lenz has no commitments for
such financing at this time and has no assurances that it will be able to obtain
additional  financing,  or  if obtained what price, terms and conditions will be
attached  to  such  financing.  The  Investor  acknowledges that Lenz intends to
issue substantial shares in several rounds of future financings, and that in the
course  of  such  issuances, the Investor's percentage ownership in Lenz will be
substantially  diluted.

          (i)     Independent Investigation.  In making her decision to purchase
                  -------------------------
the  Shares, the Investor has relied solely upon independent investigations made
by her or by her Investment Advisor (if any) and information received from Lenz.
She  has  received  no  representation  or  warranty  from  Lenz  or  any of its
affiliates,  employees  or  agents,  except  as  set  forth  herein.

          (j)     Accuracy and Survival of Representations.  Each representation

Investor  to  Lenz  is  true,  correct  and  complete  in  all  respects.  All

requirements  under  the  Act.

date  of the issuance of the Shares, as if made on and as of such date and shall
survive  such  issuance.
