representations and warranties  contained in this Agreement,  the parties hereby

         1.       Issuance of Securities, Payment and Delivery.

                  a. Sale of Securities.  Subject to the terms and conditions of

         such later date as is agreed  upon in writing by the  Investor  and the
         Corporation (the  "Closing"),  and the Company agrees to sell and issue
         to the Investor that number of shares of the Corporation's Common Stock
         set forth on  Schedule 1 (the  "Shares")  at $0.12  (twelve  cents) per

                  b.  Payment and  Delivery.  The  Investor  shall  purchase the

         funds.

         2.       Deliveries  at  Closing.  At  the  Closing  or  thereafter  as
         indicated:

                  a.  The  Corporation  and the  Investor  will  at the  Closing

         Registration Rights Agreement (as defined in Section 6 below);

                  b. The Investor  will provide the  Corporation  at the Closing
         with payment in immediately  available funds of the aggregate amount of
         the Purchase Price;

                  c. The  Corporation  will deliver  within sixty (60)  business

                  d. Upon the written  request of the Investor,  the Corporation
         shall deliver to the Investor written evidence reasonably  satisfactory
         to the  Investor  that the  condition  set forth in Section 3 below has
         been satisfied.

         3.       Condition to Closing.  It is  expressly  agreed by the parties
         that the closing of the transactions  contemplated by this Agreement is
         conditional  upon the Corporation  entering into one or more definitive
         written  agreements with one or more third parties or affiliates of the
         Investor or the Company to purchase the Corporation's  Common Stock on,
         or before,  the Closing,  the purchase  price(s) of which when combined
         with  the  Purchase  Price  of the  Shares  purchased  by the  Investor
         hereunder,  will equal at least U.S.$2.5  million in the aggregate.  In
         the event that the foregoing  condition is not satisfied on, or before,
         the date of the Closing, the Closing shall not occur and this Agreement
         shall automatically terminate without obligation or liability of either
         party.

         4.       Corporation's  Representations and Warranties. The Corporation
         hereby represents and warrants to the Investor that as of the Closing:

                  a. Corporate  Organization and Standing.  The Corporation is a
         corporation duly organized, validly existing and in good standing under
         the laws of the State of California.  The Corporation has the requisite
         corporate power to carry on its business as presently conducted, and as
         proposed or  contemplated  to be conducted in the future,  and to enter
         into  and  carry  out  the   provisions  of  this   Agreement  and  the
         transactions contemplated under this Agreement.

                  b.  Authorization.  All  corporate  action  on the part of the
         Corporation,   its  directors  and   shareholders   necessary  for  the
         authorization, execution, delivery and performance of this Agreement by
         the  Corporation  and  the  performance  of all  of  the  Corporation's
         obligations hereunder has been taken. This Agreement, when executed and
         delivered  by the  Corporation,  shall  constitute  a valid and binding
         obligation  of the  Corporation,  enforceable  in  accordance  with its
         terms,  except as may be limited by  principles of public  policy,  and
         subject  to  laws  of  general  application   relating  to  bankruptcy,
         insolvency  and the  relief  of  debtors  and  rules  of law  governing
         specific  performance,  injunctive relief or other equitable  remedies.
         The  Shares,  when issued in  compliance  with the  provisions  of this
         Agreement, will be validly issued, fully paid and non-assessable

                  c.  No  Breach.  The  issue  and  sale  of the  Shares  by the
         Corporation  does not and will not conflict  with and does not and will
         not  result  in a  breach  of  any of the  terms  of the  Corporation's
         incorporating  documents or any  agreement or  instrument  to which the
         Corporation  is a  party.  The  consummation  of  the  transactions  or
         performance of the obligations  contemplated by this Agreement will not
         result in a breach of any term of, or constitute a default  under,  any
         statute, indenture, mortgage, or other agreement or instrument to which
         the  Corporation  or any of its  subsidiaries  is or are a party  or by
         which any of them is or are bound.

                  d. Pending or Threatened  Claims.  Neither the Corporation nor
         any of its  subsidiaries  is a party to any action,  suit or proceeding
         which could materially affect its business or financial condition,  and
         no such actions,  suits or proceedings  are  contemplated  or have been
         threatened.

                                       2


         5.       Investor   Representations   and   Warranties.   The  Investor
         represents and warrants to the Corporation that:

                  a.   Account.   The  Investor  is  acquiring  the  Shares  for
         investment  for its own account,  and not with a view to, or for resale
         in connection  with, any  distribution  thereof,  and it has no present
         intention of selling or  distributing  any of the Shares (but by making
         this representation the Investor is not agreeing to hold the Shares for
         any minimum period of time).  The Investor  understands that the Shares
         have not been  registered  under the Securities Act of 1933, as amended
         (the  "Securities  Act") by reason  of a  specific  exemption  from the
         registration provisions of the Securities Act which depends upon, among
         other  things,  the bona fide  nature of the  investment  as  expressed
         herein.

                  b. Access to Data.  The  Investor  has had an  opportunity  to
         discuss the  Corporation's  business,  management and financial affairs
         with its management and to obtain any additional  information which the
         Investor has deemed  necessary or appropriate  for deciding  whether or
         not to purchase  the  Shares,  and has had an  opportunity  to receive,
         review and understand the  disclosures  and  information  regarding the
         Corporation's  financial statements,  capitalization and other business
         information as set forth in  Corporation's  filings with the Securities
         and Exchange  Commission (the "SEC Filings") which are all incorporated
         herein by reference, together with all exhibits referenced therein. The
         Investor  acknowledges that no representations  or warranties,  oral or
         written,  have been made by the Corporation or any agent thereof except
         as set forth in this Agreement.

                  c. No Fairness  Determination.  The  Investor is aware that no
         federal, state or other agency has made any finding or determination as
         to the  fairness  of the  investment,  nor made any  recommendation  or
         endorsement of the Shares.

                  d. Knowledge And  Experience.  The Investor has such knowledge
         and experience in financial and business matters, including investments
         in other  start-up  companies,  that it is  capable of  evaluating  the
         merits and risks of the  investment  in the  Shares,  and it is able to
         bear the economic  risk of such  investment.  Further,  the  individual
         executing this Agreement has such knowledge and experience in financial
         and business matters that he/it is capable of utilizing the information
         made available to him/it in connection with the offering of the Shares,
         of  evaluating  the merits and risks of an investment in the Shares and
         of making an informed  investment  decision with respect to the Shares,
         including  assessment  of the Risk Factors set forth in the SEC Filings
         which are incorporated herein by reference.

                  e. Limited Public Market.  The Investor is aware that there is
         currently  a very  limited  "over-the-counter"  public  market  for the
         Corporation's  registered  securities and that the Corporation became a
         "reporting  issuer"  under  the  Securities  Exchange  Act of 1934,  as
         amended,  on  January  27,  1995.  There  is no  guarantee  that a more
         established  public market will develop at any time in the future.  The
         Investor  understands  that the Shares are all unregistered and may not
         presently  be sold in even this  limited  public  market.  The Investor
         understands  that the Shares  cannot be readily sold or  liquidated  in
         case  of an  emergency  or  other  financial  need.  The  Investor  has
         sufficient  liquid assets available so that the purchase and holding of
         the Shares will not cause it undue financial difficulties.

                                       3

                  f. Authority. If Investor is a corporation, partnership, trust
         or estate:  (i) the individual  executing and delivering this Agreement
         on  behalf  of the  Investor  has  been  duly  authorized  and is  duly
         qualified to execute and deliver  this  Agreement on behalf of Investor
         in connection with the purchase of the Shares and (ii) the signature of
         such individual is binding upon Investor.

                  g.  Investment  Experience.  The  Investor  is an  "accredited
         investor" as that term is defined in  Regulation D  promulgated  by the
         Securities  and Exchange  Commission.  The term  "Accredited  Investor"
         under Regulation D refers to:

                      (iii) Any  private  business  development  Corporation  as

                                       4


         knowledge and  experience in financial and business  matters that he is
         capable  of  evaluating  the  merits  and  risks  of  the   prospective
         investment; or

                      (viii) Any  entity in which all of the  equity  owners are
         accredited investors.

                      (ix) As used in this  Section  4(g),  the term "net worth"
         means the  excess  of total  assets  over  total  liabilities.  For the
         purpose of  determining a person's net worth,  the principal  residence
         owned by an individual should be valued at fair market value, including
         the cost of improvements,  net of current encumbrances. As used in this
         Section 4(g),  "income" means actual economic income,  which may differ
         from adjusted  gross income for income tax purposes.  Accordingly,  the
         undersigned  should  consider  whether  it should add any or all of the
         following items to its adjusted gross income for income tax purposes in
         order to reflect  more  accurately  its  actual  economic  income:  Any
         amounts attributable to tax-exempt income received, losses claimed as a
         limited  partner in any  limited  partnership,  deductions  claimed for
         depletion,  contributions  to an  IRA or  Keogh  retirement  plan,  and
         alimony payments.

         6.       Lock-Up/Registration   Rights.  Except  for  the  registration
         rights  granted  pursuant  to the  Registration  Rights  Agreement  (as
         defined in this Section 6), the Investor  acknowledges  and agrees that
         the Shares may be subject to certain restrictions on transfer following
         a  registered  public  offering  of  the  Corporation's  securities  as
         provided  in  this  Section  6. In  connection  with  any  underwritten
         registration of the Corporation's securities, the Investor agrees, upon
         the  request  of  the  underwriters   managing  such  offering  of  the
         Corporation's  securities,  if applicable,  not to sell, make any short
         sale of,  loan,  grant any option  for the  purchase  of, or  otherwise
         dispose of any Shares (other than those  included in the  registration)
         without  the  prior  written  consent  of  the   Corporation   and,  if
         applicable,  such underwriters,  as the case may be, for such period of
         time,  not to exceed  thirty (30) days  before and one  hundred  eighty
         (180)  days,  after  the  effective  date of such  registration  as the
         Corporation or the underwriters may specify;  provided,  however,  that
         all executive officers, directors and shareholders holding more than 1%
         of the fully diluted  capital stock of the  Corporation  are subject to
         the same restrictions as the Investor. The Corporation and underwriters
         may request such additional  written  agreements in furtherance of such
         standoff in the form reasonably satisfactory to the underwriter and the
         Investor.  The Corporation may also impose  stop-transfer  instructions
         with respect to the shares subject to the foregoing  restrictions until
         the end of  said  one  hundred  eighty  (180)  day or  shorter  period.
         Contemporaneous  with the execution of this Agreement,  the Corporation
         and the Investor shall enter into a written resale  registration rights
         agreement in form and  substance  substantially  as attached  hereto as
         Exhibit A (the "Registration  Rights  Agreement"),  which shall provide
         for  the  registration  by the  Corporation  of  the  Shares  with  the
         Securities  and Exchange  Commission and such states as may be required
         by  the  Investor  according  to  the  terms  of  such  agreement.  The
         obligations  of the  Corporation  pursuant to this Section hereof shall
         cease and  terminate  upon the earlier to occur of (i) such time as all
         of the Shares  have been  resold or (ii) such time as all of the Shares
         may be sold during any 90 day period  pursuant  to Rule 144,  including
         Rule 144(k) or (iii) upon the second  anniversary date of the effective
         date of this Agreement.

         7.       Restrictive  Legends.  Each certificate  evidencing the Shares
         which the  Investor  may  acquire  hereunder  and any other  securities
         issued upon any stock split, stock dividend, recapitalization,  merger,
         consolidation  or  similar  event  (unless  no longer  required  in the

                                       5


         opinion of the counsel for the Corporation) shall be imprinted with one
