         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 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 $4 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

                                       2
<PAGE>

         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.

         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 other 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 is capable of utilizing  the  information
         made available to him 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
         and 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

                                       3
<PAGE>

         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

                  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:

         $5,000,000;  employee  benefit  plan within the meaning of the Employee
         Retirement  Income Security Act of 1974, if the investment  decision is
         made by a plan  fiduciary,  as defined  in  Section  3(21) of such Act,
         which  is  either  a bank,  savings  and  loan  association,  insurance
         Corporation,  or  registered  investment  adviser,  or if the  employee
         benefit  plan has  total  assets  in  excess  of  $5,000,000  or,  if a
         self-directed  plan,  with  investment  decision made solely by persons
         that are accredited investors;

                           (iii) Any private business development Corporation as

         acquiring  the  Securities  offered,  with  total  assets  in excess of
         $5,000,000;

                                       4
<PAGE>

                           (vi) Any natural person who had an individual  income
         in excess of $200,000  during each of the  previous  two years or joint
         income with that person's spouse in excess of $300,000 in each of those
         years and has a  reasonable  expectation  of  reaching  the same income
         level in the current year;

                           (vii)  Any  trust,  with  total  assets  in excess of
         $5,000,000,  not  formed for the  specific  purpose  of  acquiring  the
         Securities offered, whose purchase is directed by a person who has such
         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,  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  fourteen (14) 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 (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

                                       5
<PAGE>

         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
         opinion of the counsel for the Corporation) shall be imprinted with one
         or more legends substantially in the following form:

         THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
         UNDER  THE  SECURITIES  ACT OF 1933,  AS  AMENDED,  OR UNDER  ANY STATE
         SECURITIES  LAWS,  AND MAY BE OFFERED AND SOLD ONLY IF SO REGISTERED OR
         AN EXEMPTION FROM REGISTRATION IS AVAILABLE. THE HOLDER OF THESE SHARES
         MAY BE REQUIRED TO DELIVER TO THE COMPANY,  IF THE COMPANY SO REQUESTS,
         AN OPINION OF COUNSEL (REASONABLY SATISFACTORY IN FORM AND SUBSTANCE TO
         THE COMPANY) TO THE EFFECT THAT AN EXEMPTION  FROM  REGISTRATION  UNDER
         THE SECURITIES ACT (OR  QUALIFICATION  UNDER STATE  SECURITIES LAWS) IS
         AVAILABLE  WITH  RESPECT TO ANY  TRANSFER OF THESE  SHARES THAT HAS NOT
         BEEN SO REGISTERED (OR QUALIFIED).

         THE COMPANY IS AUTHORIZED TO ISSUE MORE THAN ONE CLASS OF STOCK. A COPY
         OF THE PREFERENCES, POWERS, QUALIFICATIONS AND RIGHTS OF EACH CLASS AND
         SERIES  WILL BE  PROVIDED  TO EACH  STOCKHOLDER  WITHOUT  CHARGE,  UPON
         WRITTEN REQUEST.

         The Corporation shall be entitled to enter stop transfer notices on its
         transfer books with respect to the Securities.

         8.  Indemnification  of the Investor.  The Corporation hereby agrees to
         indemnify,  defend and hold the Investor  harmless from and against any
         and all damages,  losses, expenses or other costs (including reasonable
         attorneys'  fees and expenses)  incurred by the Investor as a result of
         the  Corporation's  breach of any  representation  or  warranty  of the
         Corporation set forth in this Agreement.

         9. Confidential  Information.  The parties agree that, except as may be
         set forth on the attached  Schedule 2, the Corporation has not provided
         the Investor with any material  non-public  information with respect to
         the Corporation or its activities ("Confidential Information"), and the
         Corporation   agrees  to  publicly   disclose  the  substance  of  such
         Confidential Information within the applicable time period set forth on
         the attached Schedule 2 (unless such Confidential  Information  becomes
         moot by such  date).  The  Investor  understands  and agrees  that such

         comparable  terms as is possible.  In the event that the parties cannot
         reach  a  mutually  agreeable  and  enforceable  replacement  for  such
         provision,  then  (a)  such  provision  shall  be  excluded  from  this
         Agreement,  (b) the balance of the Agreement shall be interpreted as if
         such  provision  were so excluded and (c) the balance of the  Agreement
         shall be enforceable in accordance with its terms.

                  (d)   furnish  to  each   Holder  such  number  of  copies  of

         3. Indemnification

                  (a) The Company  agrees to indemnify  and hold  harmless  each
Holder, such Holder's directors, officers, partners, agents, each underwriter of
Registered Shares, and each Person who controls any of the foregoing (within the
meaning of Section 15 of the Securities Act) (each an "Indemnified  Party") from
and against any losses, claims, damages or liabilities to which such Indemnified
Party may become subject (under the Securities Act or otherwise) insofar as such
losses,  claims,  damages or  liabilities  (or actions or proceedings in respect
thereof)  arise  out  of,  or  are  based  upon,  any  untrue  statement  in the
Registration  Statement,  or arise out of any  failure by the Company to fulfill
any  undertaking  included  in the  Registration  Statement  or arise  under the
Securities  Act or any other  statute  or at  common  law and the  Company  will
reimburse  such  Indemnified  Party for any  reasonable  legal or other expenses
reasonably incurred in investigating,  defending or preparing to defend any such
action,  proceeding or claim;  provided,  however, that the Company shall not be
liable in any such case to the extent that such loss, claim, damage or liability
arises out of, or is based upon, an untrue  statement made in such  Registration
Statement in reliance upon and in conformity with written information  furnished
to the Company by or on behalf of such Indemnified Party specifically for use in
preparation  of the  Registration  Statement  or the  failure of such  Holder to
comply  with  the  covenants  and  agreements  contained  in  Section  4  hereof
respecting  the sale of the  Registrable  Shares or any untrue  statement in any
prospectus that is corrected in any subsequent  prospectus that was delivered to
the Holder prior to the pertinent sale or sales by the Holder.

                  (b)  Each  Holder,   severally  and  not  jointly,  agrees  to
indemnify and hold  harmless the Company (and each person,  if any, who controls
the Company within the meaning of Section 15 of the Securities Act, each officer
of the Company who signs the  Registration  Statement  and each  director of the
Company) from and against any losses,  claims,  damages or  liabilities to which
the Company (or any such

                                      -3-
<PAGE>

officer,   director  or  controlling  person)  may  become  subject  (under  the
Securities  Act or  otherwise),  insofar  as such  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect  thereof) arise out of, or are
based upon, any failure to comply with the covenants and agreements contained in
Section  5 hereof  respecting  sale of the  Registrable  Shares,  or any  untrue
statement  contained in the Registration  Statement if, but only if, such untrue
statement was made in reliance upon and in conformity  with written  information
furnished by or on behalf of such Holder  specifically for use in preparation of
the  Registration  Statement and such Holder will reimburse the Company (or such
officer,  director or controlling  person), as the case may be, for any legal or
other expenses reasonably  incurred in investigating,  defending or preparing to
defend any such action, proceeding or claim; provided that in no event shall any
indemnity by a Holder  under this Section 3 exceed the net proceeds  received by
such Holder from the sale of the Registrable Shares covered by such Registration
Statement.

                  (c)  Promptly  after  receipt by any  indemnified  person of a
notice of a claim or the  beginning of any action in respect of which  indemnity
is to be sought against an indemnifying  person pursuant to this Section 3, such
indemnified person shall notify the indemnifying person in writing of such claim
or  of  the  commencement  of  such  action,  and,  subject  to  the  provisions
hereinafter  stated,  in case  any  such  action  shall be  brought  against  an
indemnified  person  and such  indemnifying  person  shall  have  been  notified
thereof, such indemnifying person shall be entitled to participate therein, and,
to the  extent it shall  wish,  to assume  the  defense  thereof,  with  counsel
reasonably  satisfactory  to such  indemnified  person.  After  notice  from the
indemnifying  person to such  indemnified  person of its  election to assume the
defense  thereof,   such  indemnifying  person  shall  not  be  liable  to  such
indemnified  person  for  any  legal  expenses  subsequently  incurred  by  such
indemnified  person in connection with the defense thereof;  provided,  however,
that if there  exists or shall exist a conflict  of interest  that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof,  the indemnified person shall be entitled to
retain  its  own  counsel  at  the  expense  of  such  indemnified   person.  No
indemnifying party in the defense of any such claim or litigation shall,  except
with the consent of each indemnified party,  consent to entry of any judgment or
enter into any settlement that does not include as an unconditional term thereof
the giving by the claimant or plaintiff to such  indemnified  party of a release
from all liability in respect of such claim or  litigation,  and no  indemnified
party shall  consent to entry of any judgment or settle such claim or litigation
without the prior written consent of the indemnifying party.

                  (d) If the  indemnification  provided for in this Section 3 is
held by a court of competent  jurisdiction  to be  unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or

                                      -4-
<PAGE>

expense  referred  to  therein,   then  the  indemnifying   party,  in  lieu  of
indemnifying  such indemnified  party hereunder,  shall contribute to the amount
paid or payable by such indemnified  party as a result of such loss,  liability,
claim,  damage,  or expense in such  proportion as is appropriate to reflect the
relative fault of the indemnifying  party on the one hand and of the indemnified
party on the other in connection  with the statements or omissions that resulted
in such loss, liability, claim, damage, or expense as well as any other relevant
equitable  considerations.  The relative fault of the indemnifying  party and of
the  indemnified  party shall be determined by reference to, among other things,
whether the untrue or alleged untrue  statement of material fact or the omission
to state a material  fact relates to  information  supplied by the  indemnifying
party or by the indemnified party and the parties'  relative intent,  knowledge,
access to  information,  and opportunity to correct or prevent such statement or
omission. No Person guilty of fraudulent  misrepresentation  (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  from
any   Person  who  was  not   guilty  of  such   fraudulent   misrepresentation.
Notwithstanding anything to the contrary contained herein, any contribution by a
Holder hereunder shall not exceed the net proceeds  received by such Holder from
the sale of the Registrable Shares covered by the Registration Statement.

         4. Transfer of Shares After  Registration;  Notice.  Each Holder hereby
covenants with the Company not to make any sale of the Registrable  Shares after
registration  without effectively  causing the prospectus  delivery  requirement
under the Securities Act to be satisfied.  Each Holder  acknowledges  that there
may be times when the Company must suspend the use of the  prospectus  forming a
part of the  Registration  Statement  until  such  time as an  amendment  to the
Registration  Statement has been filed by the Company and declared  effective by
the  Commission,  or until  such time as the  Company  has filed an  appropriate
report with the  Commission  pursuant to the Exchange  Act.  Each Holder  hereby
covenants  that it  will  not  sell  any  Registrable  Shares  pursuant  to said
prospectus  during the period  commencing at the time at which the Company gives
the Holder prior written notice of the suspension of the use of said  prospectus
and ending at the time the Company  gives the Holder prior  written  notice that
the Holder may thereafter  effect sales pursuant to said  prospectus;  provided,
however, that no such postponements shall be permitted for more than one hundred
twenty (120) days in the  aggregate  during any 12 month  period.  The foregoing
provisions of this Section 4 shall in no manner diminish or otherwise impair the
Company's obligations under Section 2.

         5. Reporting Requirements.

                  (a) The Company  agrees  during the term of this  Agreement to
use its reasonable efforts to:

                                      -5-
<PAGE>

                           (i) make and keep public  information  available,  as
those terms are understood and defined in Rule 144 under the Securities Act;

                           (ii) file with the  Commission in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act; and

                           (iii) so long as any of the Holders  own  Registrable
Shares, to furnish to the Holders forthwith upon request (1) a written statement
by the Company as to whether it complies with the reporting requirements of said
Rule 144, the  Securities Act and the Exchange Act, or whether it qualifies as a
registrant whose securities may be resold pursuant to Commission Form S-3, (2) a
copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company, and (3) such other information as
may be reasonably requested in availing the Holders of any rule or regulation of
the Commission that would permit the selling of the  Registrable  Shares without
registration.

         6. Termination of Obligations.  The obligations of the Company pursuant
to  Sections  2 through 5 hereof  with  respect to any  Holder  shall  cease and
terminate  upon the earlier to occur of (i) such time as all of the  Registrable
Shares  have  been  resold  by  such  Holder  or  (ii)  such  time as all of the
Registrable  Shares held by such  Holder may be sold  during any 3 month  period
pursuant  to  Rule  144,  including  Rule  144  (k) or  (iii)  upon  the  second
anniversary date of the Effective Date.

         7. Assignability of Registration  Rights.  The Registration  rights set
forth in Section 2 are assignable only to assignees  acquiring all of a Holder's
Registrable  Shares held at the time of  assignment.  Provided  further that the
Company  shall not be  obligated  to file any  post-effective  amendment  to the
Registration  Statement solely for the purpose of adding such assignee(s) to the
Registration Statement more than once during any consecutive six-month period.

         8. Miscellaneous.

                  (a) Additional Parties/Consent to Amendments.  Each Person who
enters into a Stock Purchase Agreement on, or before,  September 30, 2002, shall
be  deemed a Holder  under  this  Agreement  accorded  the  registration  rights
afforded to all Holders as contemplated herein. In addition, except as otherwise
expressly  provided  herein,  the  provisions  of this  Agreement may be amended
and/or  the  provisions  hereof  waived,  only with the  written  consent of the
Company  and  of  Holders  holding  fifty-one  percent  (51%)  or  more  of  the
Registrable  Shares  at the  time  held  by  all  Holders.  Notwithstanding  the
foregoing,  no  amendment  or  waiver  may  affect  any  Holder  in  any  manner
differently  from any other  Holder  without the  written  consent of

                                      -6-

such first  mentioned  Holder.  No course of dealing between the Company and any
Holder or any delay in  exercising  any rights  hereunder or under the Company's
Articles  of  Incorporation  will  operate as a waiver of any rights of any such
Holder.

                  (b)  Successors  and Assigns.  All  covenants  and  agreements
contained in this  Agreement by or on behalf of any of the parties  hereto shall
bind and inure to the benefit of the  respective  successors  and assigns of the
parties hereto whether so expressed or not.

                  (c)  Severability.  Each provision of this Agreement  shall be
interpreted  in such manner as to be effective and valid under  applicable  law,
but if any  provision of this  Agreement is held to be  prohibited by or invalid
under  applicable law, such provision shall be ineffective only to the extent of
such  prohibition  or  invalidity,  without  invalidating  the remainder of this
Agreement.

                  (d)  Counterparts.  This  Agreement  may be executed in two or
more counterparts, any one of which need not contain the signatures of more than
one party,  but all such  counterparts  when taken together shall constitute one
and the same Agreement.

                  (e) Descriptive  Headings.  The  descriptive  headings of this
Agreement are inserted for convenience only and do not constitute a part of this
Agreement.

                   ADDENDUM BETWEEN THE COMPANY AND INVESTOR.

         A. The  Company  shall  use  reasonable  efforts  to (i)  register  and
qualify, unless an exemption from registration or qualification applies, all the
Registrable  Shares  of the  above  named  Holder  covered  by the  Registration
Statement under all securities or "blue sky" laws of such  jurisdictions  in the
United  States that are required by such Holder upon written  notice  thereof to
the  Company,  (ii)  prepare and file in those  jurisdictions,  such  amendments
(including post-effective  amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness  thereof during
the registration period set forth in Section 6 of the Agreement, (iii) take such
other  actions  as  may  be  necessary  to  maintain  such   registrations   and
qualifications  in effect at all times  during the period set forth in Section 6
of the  Agreement,  and (iv)  take all other  actions  reasonably  necessary  or
advisable  to qualify  the  Registrable  Shares of such  Holder for sale in such
jurisdictions;  provided,  however,  that the  Company  shall not be required in
connection  therewith or as a condition thereto to (x) qualify to do business in
any  jurisdiction  where it would not  otherwise  be required to qualify but for
this  paragraph A, (y) subject itself to taxation in any such  jurisdiction,  or
(z) file a general consent to service of process in any such jurisdiction.

         B. If the Registration Statement covering all the Registrable Shares of
the above named Holder and required to be filed by the Company  pursuant to this
Agreement is not declared effective by the SEC within 30 calendar days after the
date set forth in Section 2(a) of the Agreement for any reason, then, as partial
relief  for the  damages  to such  Holder  by  reason  of any  such  delay in or
reduction of its ability to sell its Registrable  Shares (which remedy shall not
be  exclusive  of any  other  remedies  available  at law or in  equity  to such
Holder), the Company shall grant to such Holder, free of charge, Common Stock in
an amount equal to 1% of the Common Stock  purchased by such Holder  pursuant to
its previously  executed Stock Purchase Agreement for every complete 30 calendar
day period  after the date set forth in Section 2(a) of the  Agreement  that the
Registration Statement is not declared effective by the SEC. Any such additional
Common  Stock  granted to such  Holder  pursuant  to this  paragraph  B shall be
granted  by the  Company  within 45 days  after  the date that the  Registration
Statement is declared  effective  and the Company  shall  promptly  include such
additional Common Stock in the Registration Statement.
