Optionee an option  ("Option")  to purchase the total number of shares of Common
Stock of the Company set forth above  ("Shares") at the Exercise Price Per Share
set forth above ("Exercise  Price"),  subject to all of the terms and conditions
of this  Agreement  and the Plan.  If  designated  as an Incentive  Stock Option
above,  the Option is intended to qualify as an "incentive stock option" ("ISO")
within the  meaning of Section  422 of the  Internal  Revenue  Code of 1986,  as
amended  ("Code").  Subject to the Plan,  only  Employees  of the Company  shall

and references, which are undefined in this Agreement, shall have the definition
and meaning ascribed to them in the Plan,  including,  without  limitation,  the
definition of the terms Employee and Consultant.

2. Exercise  Price.  The Exercise  Price, is not less than the fair market value
per share of Common  Stock on the date of grant,  as  determined  by the  Board;
provided,  however,  in  the  event  Optionee  is an  Employee  and  owns  stock
representing  more than ten percent (10%) of the total combined  voting power of
all classes of stock of the Company or of its Parent or Subsidiary  corporations
immediately  before the Option is granted,  said exercise price is not less than
one  hundred ten  percent  (110%) of the fair  market  value per share of Common
Stock on the date of grant as determined by the Board.

3. Exercise of Option.  Subject to the vesting schedule contained herein and the
other  conditions set forth in this Agreement,  all or part of the Option may be
exercised  prior to its  expiration  from the first vesting date set forth above
("First  Vesting Date") up to and including 5:00 p.m.  Pacific  Standard Time on
the expiration date set forth above ("Expiration Date") at the time or times set
forth herein in accordance with the provisions of the Plan as follows:

         (i)      Vesting:

                (a)   The  Option  shall  become  exercisable  in the  amount of
                      100,000  shares upon the assembly and  commissioning  of a
                      base line  production  system as  contemplated  within the
                      Company's  phased  build  out  plan  for  a  solar  module
                      manufacturing facility.

                (b)   This  Option  shall  become  exercisable  in the amount of
                      150,000  shares upon the  production of a commercial  size
                      working sample of the Company's  planned  tandem  junction
                      amorphous silicon solar module as contemplated  within the
                      Company's  phased  build  out  plan  for  a  solar  module
                      manufacturing facility.

                (c)   This  Option  shall  become  exercisable  in the amount of
                      50,000 shares upon the assembly and  commissioning  of the
                      initial  25 mega watt  production  system as  contemplated
                      within  the  Company's  phased  build out plan for a solar
                      module manufacturing facility.

                      Share.

                                    2 of 17

<PAGE>

                (e)   In the  event of  Optionee's  death,  disability  or other
                      termination  of  employment,  the  exercisability  of  the
                      Option is governed  by Sections 7, 8 and 9 below,  subject
                      to the limitations contained in subsection 3(i)(d) below.

                (f)   In no event may the Option be exercised  after the date of
                      expiration  of the term of the Option as set forth in Sec-
                      tion 11 below.

         (ii)(ii) Method  of  Exercise.  The  Option  shall  be  exercisable  by
                  written  notice which shall state the election to exercise the
                  Option, the number of Shares in respect of which the Option is
                  being exercised, and such other representations and agreements
                  as to the  holder's  investment  intent  with  respect to such
                  shares  of  Common  Stock as may be  required  by the  Company
                  pursuant to the  provisions of the Plan.  Such written  notice
                  shall be signed by Optionee  and shall be  delivered in person
                  or by  certified  mail to the  President,  Secretary  or Chief
                  Financial Officer of the Company.  The written notice shall be
                  accompanied by payment of the exercise price.

          (iii)   Compliance  with Law. No Shares will be issued pursuant to the
                  exercise of an Option  unless such  issuance and such exercise
                  shall  comply  with  all  relevant  provisions  of law and the
                  requirements  of any stock  exchange or quotation  medium upon
                  which the Shares may then be listed or quoted.  Assuming  such
                  compliance,  for  income  tax  purposes  the  Shares  shall be
                  considered  transferred  to the  Optionee on the date on which
                  the Option is exercised with respect to such Shares.

         (iv)     Adjustments,  Merger,  etc. The number and class of the Shares
                  and/or  the  exercise  price  specified  above  are subject to
                  appropriate  adjustment in the event of changes in the capital
                  stock of  the  Company  by  reason  of stock  dividends, stock
                  splits, combination or r ecombination of shares, reclassifica-
                  tions,  mergers,  consolidations,  reorganizations or liquida-
                  tions.  Subject to any required action of the stockholders  of
                  the Company,  if the  Company  shall be the surviving corpora-
                  tion in any merger or consolidation, the Option (to the extent
                  that it  is still  outstanding) shall  pertain to and apply to
                  the  securities to which a holder of the same number of shares
                  of Common Stock that are then subject to the Option would have
                  been entitled. A dissolution or liquidation of the Company, or
                  a merger or consolidation in which the Company is not the sur-
                  viving corporation, will cause the Option to terminate, unless
                  the  agreement  or  merger  or consolidation  shall  otherwise
                  provide,  provided  that  the Optionee   shall,  if  the Board
                  expressly authorizes, in such event have the right immediately
                  prior to such dissolution or liquidation, or merger or consoli
                  -dation, to  exercise  the Option  in  whole  or part.  To the
                  extent that the foregoing  djustments relate to stock or secur
                  -ities of the Company,  such adjustments  shall be made by the
                  Board,  whose determination  in that  respect shall  be final,
                  binding and conclusive.

4. Optionee's  Representations.  By receipt of the Option, by its execution, and
by its  exercise in whole or in part,  Optionee  represents  to the Company that
Optionee understands that:

         (i)      Both the Option and any Shares purchased upon its exercise are
                  securities, the issuance by the Company of which requires com-
                  pliance with federal and state securities laws;

                                    3 of 16

<PAGE>

         (ii)     These  securities  are made  available to Optionee only on the
                  condition that Optionee makes the representations contained in
                  this Section 4 to the Company;

         (iii)    Optionee has made a reasonable investigation of the affairs of
                  the Company  sufficient  to be well  informed as to the rights
                  and the value of these securities;

         (iv)     Optionee  understands  that the securities have not been regi-
                  stered under  the Securities  Act  of 1933,  as  amended  (the
                  "Act") in  reliance upon one  or more specific exemptions con-
                  tained in the Act,  which  may include  reliance  on  Rule 701
                  promulgated under the Act,  if available,  or which may depend
                  upon: (a) Optionee's bona fide investment intention in acquir-
                  ing these securities;  (b) Optionee's  intention to hold these
                  securities in  compliance with  federal and  state  securities
                  laws; (c) Optionee  having no present  intention of selling or
                  transferring  any part thereof (recognizing that the Option is
                  not transferable) in violation of applicable federal and state
                  securities  laws; and (d) there  being certain restrictions on
                  transfer of the Shares subject to the Option;

         (v)      Optionee understands that the Shares subject to the Option, in
                  addition  to  other  restrictions  on  transfer,  must be held
                  indefinitely unless subsequently  registered under the Act, or
                  unless an exemption from registration is available;  that Rule
                  144, the usual exemption from registration,  is only available
                  after the  satisfaction  of certain holding periods and in the
                  presence of a public  market for the Shares;  that there is no
                  certainty that a public market for the Shares will exist,  and
                  that  otherwise it will be  necessary  that the Shares be sold
                  pursuant to another exemption from  registration  which may be
                  difficult to satisfy; and,

         (vi)     Optionee  understands  that the certificate  representing  the
                  Shares will bear a legend  prohibiting  their  transfer in the
                  absence of their  registration  or the  opinion of counsel for
                  the Company that  registration  is not required,  and a legend
                  prohibiting their transfer in compliance with applicable state
                  securities laws unless otherwise exempted.

5. Method of Payment.  Payment of the purchase  price may be made subject to the
terms of Section 14 herein,  or by cash, check or, in the sole discretion of the
Board at the time of exercise,  promissory notes or other Shares of Common Stock
having  a fair  market  value on the date of  surrender  equal to the  aggregate
purchase price of the Shares being purchased.

6. Restrictions on Exercise.  The Option may not be exercised if the issuance of
such Shares upon such  exercise  or the method of payment of  consideration  for
such Shares  would  constitute a violation  of any  applicable  federal or state
securities  or other law or  regulation.  As a condition  to the exercise of the
Option, the Company may require Optionee to make any representation and warranty
to the Company as may be required by any applicable law or regulation.

7.  Termination  of  Status  as an  Employee  or  Consultant.  In the  event  of
termination of Optionee's  continuous  status as an Employee or  Consultant,  as
such  status  may be  determined  and  construed  by  the  Company  in its  sole
discretion  ("Continuous Status"), for any reason other than death or disability
or the  completed  term and  performance  under  any  consulting  or  employment
agreement  between the Optionee and the Company,  Optionee  may, but only within
thirty (30) days after the date of such termination, with such period subject to
extension at the sole discretion of the Company, (but in no event later than the
date of  expiration of the term of the Option as set forth in Section 11 below),
exercise  the Option to the extent that  Optionee was entitled to exercise it at
the date of such  termination.  To the extent that  Optionee was not entitled to
exercise  the Option at the date of such  termination,  or if Optionee  does not
exercise  the  Option  within  the  time  specified  herein,  the  Option  shall
terminate.

8. Disability of Optionee.  In the event of termination of Optionee's Continuous
Status  as an  Employee  or  Consultant  as a result of  Optionee's  disability,
Optionee  may,  but only within six (6) months from the date of  termination  of
employment  or consulting  relationship  (but in no event later than the date of
expiration of the term of the Option as set forth in Section 11 below), exercise
the Option to the extent  Optionee  was  entitled  to exercise it at the date of
such  termination;  provided,  however that if the  disability  is not total and
permanent  (as  defined  in  Section  22(e)(3)  of the  Code)  and the  Optionee
exercises the option within the period provided above but more than three months
after the date of termination,  the Option shall automatically be deemed to be a
Nonstatutory  Stock  Option and not an Incentive  Stock  Option;  and  provided,
further,  that if the  disability  is total and permanent (as defined in Section
22(e)(3) of the Code),  then the Optionee may, but only within one (1) year from
the date of  termination  of employment or  consulting  relationship  (but in no
event later than the date of  expiration  of the term of the Option as set forth
in Section 11 below), exercise the Option to the extent Optionee was entitled to
exercise it at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination,  or if Optionee does
not exercise  such Option (which  Optionee was entitled to exercise)  within the
time periods specified herein, the Option shall terminate.

9.       Death of Optionee. In the event of the death of Optionee:

         (i)      During the  term of the Option while an Employee or Consultant
                  of the  Company  and  having  been in Continuous  Status as an
                  Employee or  Consultant since the date of grant of the Option,
                  the Option may be exercised,  at any time  within one (1) year
                  following the date  of death (but, in the case of an Incentive
                  Stock Option, in no event later than the date of expiration of
                  the term of the Option as set  forth in Section 11 below),  by
                  Optionee's  estate or  by a  person who  acquired the right to
                  exercise the Option by bequest or inheritance, but only to the
                  extent of the right to exercise that  had  accrued at the time
                  of death of the Optionee. To the extent that such Employee  or
                  Consultant was not entitled to exercise the Option at the date
                  of death, or if such Employee, Consultant, estate or other per
                  -son does not exercise such Option (which such Employee,  Con-
                  sultant, estate or person was entitled to exercise) within the
                  one  (1) year  time period specified  herein, the Option shall
                  terminate; or,

         (ii)     During the thirty (30)  day period  specified  in Section 7 or
                  the one  (1) year period  specified  in  Section 8, after  the
                  termination of Optionee's Continuous Status as  an Employee or
                  Consultant,  the Option may be exercised,  at any  time within
                  one (1) year following  the date of death (but, in the case of

                                    5 of 16

<PAGE>

                  an Incentive  Stock Option, in no event later than the date of
                  expiration of  the term of  the Option as set forth in Section
                  11 below),  by Optionee's  estate or by a person who  acquired
                  the right to  exercise  the Option by bequest or  inheritance,
                  but only to the extent of the right to exercise that had accru
                  -ed at the date of termination. To the extent that such Employ
                  -ee or Consultant was not  entitled to exercise  the Option at
                  the date of death, or if such Employee, Consultant,  estate or
                  other person does not exercise such Option (which such Employ-
                  ee,  Consultant,  estate or   person was entitled to exercise)
                  within the  one (1)  year time  period specified  herein,  the
                  Option shall terminate.

10.  Non-Transferability  of Option.  The Option may not be  transferred  in any
manner  otherwise than by will or by the laws of descent or distribution and may
be exercised during the lifetime of Optionee, only by Optionee. The terms of the
Option shall be binding upon the executors,  administrators,  heirs,  successors
and assigns of Optionee.

11.  Term of Option.  The Option may not be  exercised  more than five (5) years
from the date of grant of the Option, and may be exercised during such term only
in accordance with the Plan and terms of the Option; provided, however, that the
term of this option, if it is a Nonstatutory  Stock Option,  may be extended for
the period set forth in Section 9(i) or Section 9(ii) in the  circumstances  set
forth in such Sections.

12. Early Disposition of Stock; Taxation Upon Exercise of Option. If Optionee is
an Employee and the Option qualifies as an ISO,  Optionee  understands  that, if
Optionee  disposes of any Shares  received under the Option within two (2) years
after the date of this  Agreement  or within one (1) year after such Shares were
transferred to Optionee, Optionee may be treated for federal income tax purposes
as having received ordinary income at the time of such disposition in any amount
generally  measured as the difference  between the price paid for the Shares and
the lower of the fair market  value of the Shares at the date of exercise or the
fair market value of the Shares at the of  disposition.  Any gain  recognized on
such  premature  sale of the Shares in excess of the amount  treated as ordinary
income may be  characterized  as capital gain.  Optionee hereby agrees to notify
the  Company  in  writing  within  thirty  (30) days  after the date of any such
disposition.  Optionee  understands that if Optionee  disposes of such Shares at
any time after the expiration of such two-year and one-year holding periods, any
gain on such sale may be  treated  as  long-term  capital  gain laws  subject to
meeting  various  qualifications.  If  Optionee  is a  Consultant  or  this is a
Nonstatutory  Stock  Option,  Optionee  understands  that,  upon exercise of the
Option, Optionee may recognize income for tax purposes in an amount equal to the
excess of the then fair market value of the Shares over the exercise price. Upon
a resale of such shares by the Optionee,  any difference  between the sale price
and the fair  market  value of the Shares on the date of  exercise of the Option
may be treated as capital gain or loss.  Optionee  understands  that the Company
may be required to withhold tax from Optionee's current  compensation in some of
the  circumstances  described  above  (and  Optionee  hereby so  authorizes  the
Company);  to the extent that Optionee's current compensation is insufficient to
satisfy the withholding  tax liability,  the Company may require the Optionee to
make a cash  payment to cover such  liability  as a condition to exercise of the
Option.

                                    6 of 17

13.  Tax  Consequences.  The  Optionee  understands  that  any of the  foregoing
references to taxation are based on federal income tax laws and  regulations now
in  effect,   and  may  not  be  applicable   to  the  Optionee   under  certain
circumstances.  The Optionee may also have adverse tax consequences  under state
or local law. The Optionee has reviewed with the Optionee's own tax advisors the
federal,   state,  local  and  foreign  tax  consequences  of  the  transactions
contemplated by this Agreement.  The Optionee is relying solely on such advisors
and  not on any  statements  or  representations  of the  Company  or any of its
agents.  The Optionee  understands that the Optionee (and not the Company) shall
be  responsible  for the Optionee's own tax liability that may arise as a result
of the transactions contemplated by this Agreement.

14. Net Issue Exercise.  Notwithstanding  any provisions herein to the contrary,
if the fair market value of one share of the  Company's  Common Stock is greater
than the Per  Share  Exercise  Price  (at the date of  calculation  as set forth
below),  in lieu of  exercising  the Option for cash,  the Optionee may elect to
receive  shares equal to the value (as  determined  below) of the Option (or the
portion  thereof  being  canceled) by  surrender of the Option at the  principal
office of the Company together with the properly endorsed Notice of Exercise and
Subscription  Form and notice of such election,  in which event the Company will
issue to the  Optionee  a number of shares of Common  Stock  computed  using the
following formula:

                  X = Y (A-B)
                      -------
                        A

          Where X = the  number of  shares  of Common  Stock to be issued to the
          Optionee

                            Y = the number of shares of Common Stock purchasable
          under  the Option  or,  if  only a  portion  of the  Option  is  being
          exercised, the portion of the Option  being  canceled  (at the date of
          such calculation)

                            A = the  fair  market  value  of  one  share  of the
          Company's Common Stock (at the date of such calculation)

                            B = Per  Share  Exercise  Price  (as adjusted to the
          date of such calculation)

         For purposes of the above  calculation,  fair market value of one share
of the  Company's  Stock  will  be the  average  of the  closing  prices  of the
Company's  shares of  Common  Stock as quoted  on the OTC  Bulletin  Board  (the
"OTCBB") (or on such other United States stock exchange or public trading market
or quotation medium on or by which the shares of the Company trade or are quoted
if, at the time of the  election,  they are not  trading or being  quoted on the
OTCBB), for the five (5) consecutive trading days immediately preceding the date
of the date the completed,  executed Notice of Exercise and Subscription Form is
received.

15.  Damages.  The parties  agree that any violation of the Option (other than a
default in the payment of money) cannot be compensated  for by damages,  and any
aggrieved  party shall have the right,  and is hereby granted the privilege,  of
obtaining  specific  performance  of  the  Option  in  any  court  of  competent
jurisdiction in the event of any breach hereunder.

16. Delay. No delay or failure on the part of the Company or the Optionee in the
exercise of any right,  power or remedy shall operate as a waiver  thereof,  nor
shall any  single or  partial  exercise  by any of them of any  right,  power or
remedy preclude other or further exercise thereof,  or the exercise of any other
right, power or remedy.

17.  Restrictions.  Notwithstanding  anything  herein to the contrary,  Optionee
understands  and agrees  that  Optionee  shall not dispose of any of the Shares,
whether  by  sale,  exchange,  assignment,   transfer,  gift,  devise,  bequest,
mortgage, pledge, encumbrance or otherwise,  except in accordance with the terms
and conditions of this Agreement, and Optionee shall not take or omit any action
which will impair the absolute and  unrestricted  right,  power,  authority  and
capacity of Optionee to sell Shares in accordance  with the terms and conditions
hereof.

Any purported transfer of Shares by Optionee that violates any provision of this
Section 17 shall be wholly void and ineffectual and shall give to the Company or
its  designee the right to purchase  from  Optionee all but not less than all of
the Shares then owned by Optionee for a period of ninety (90) days from the date
the Company first learns of the purported transfer at the Agreement Price and on
the Agreement  Terms (as those terms are defined in subsections  (vi) and (vii),
respectively,  of this  Section  17).  If the  Shares are not  purchased  by the
Company or its designee,  the purported  transfer  thereof shall remain void and
ineffectual and they shall continue to be subject to this Agreement.

The Company  shall not cause or permit the  transfer of any Shares to be made on
its books except in accordance with the terms hereof.

         (i)      Permitted Transfers.

                  (a)      Optionee may sell, assign or transfer any Shares held
                           by the  Optionee  but  only  by  complying  with  the
                           provisions of subsection (iv) of this Section 17.

                  (b)      Optionee may sell, assign or transfer any Shares held
                           by the Optionee without complying with the provisions
                           of  subsection  (iv) by obtaining  the prior  written
                           consent of the Company's  shareholders  owning 50% of
                           the  then  issued  and  outstanding   shares  of  the
                           Company's Common Stock (determined on a fully diluted
                           basis) or a majority  of the  members of the Board of
                           Directors   of  the   Company,   provided   that  the
                           transferee  agrees  in  writing  to be  bound  by the
                           provisions  of the Option and the transfer is made in
                           accordance with any other  restrictions or conditions
                           contained  in the written  consent and in  accordance
                           with applicable federal and state securities laws.

                  (c)      Upon  the  death  of  Optionee,  Shares  held  by the
                           Optionee   may  be   transferred   to  the   personal
                           representative   of  the  Optionee's  estate  without
                           complying  with the  provisions of  subsection  (iv).
                           Shares so  transferred  shall be subject to the other
                           provisions  of the Option,  including in  particular,
                           and without limitation, subsection (v).

         (ii)     No Pledge.  Unless a majority  of the  members of the Board of
                  Directors  consent,  Shares may not be pledged,  mortgaged  or

                                    8 of 17

                  otherwise encumbered to secure indebtedness for money borrowed
                  or any other obligation for which the Optionee is primarily or
                  secondarily liable.

         (iii)    Stock  Certificate  Legend.  Each stock certificate for Shares
                  issued  to the  Optionee  shall  have  conspicuously  written,
                  printed,  typed or stamped upon the face thereof,  or upon the
                  reverse  thereof  with a  conspicuous  reference  on the  face
                  thereof, one or both of the following legends:

                  THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE BEEN ISSUED
                  WITHOUT  REGISTRATION  UNDER THE  SECURITIES  ACT OF 1933,  AS
                  AMENDED,  AND  MAY  NOT  BE  TRANSFERRED  IN  THE  ABSENCE  OF
                  REGISTRATION  THEREUNDER OR AN APPLICABLE  EXEMPTION  FROM THE
                  REGISTRATION  REQUIREMENTS OF SUCH ACT. SUCH SHARES MAY NOT BE
                  SOLD, ASSIGNED,  TRANSFERRED,  OR OTHERWISE DISPOSED OF IN ANY
                  MANNER EXCEPT IN  ACCORDANCE  WITH AND SUBJECT TO THE TERMS OF
                  THE STOCK OPTION AGREEMENT,  A COPY OF WHICH IS ON FILE AT THE
                  PRINCIPAL  OFFICE OF THE  COMPANY.  UNLESS A  MAJORITY  OF THE
                  MEMBERS OF THE BOARD OF DIRECTORS  CONSENT,  SUCH STOCK OPTION
                  AGREEMENT PROHIBITS ANY PLEDGE,  MORTGAGE OR OTHER ENCUMBRANCE
                  OF SUCH SHARES TO SECURE ANY  OBLIGATION OF THE HOLDER HEREOF.
                  EVERY  CREDITOR OF THE HOLDER HEREOF AND ANY PERSON  ACQUIRING
                  OR PURPORTING TO ACQUIRE THIS CERTIFICATE OR THE SHARES HEREBY
                  EVIDENCED  OR ANY INTEREST  THEREIN IS HEREBY  NOTIFIED OF THE
                  EXISTENCE OF SUCH STOCK OPTION AGREEMENT,  AND ANY ACQUISITION
                  OR PURPORTED  ACQUISITION  OF THIS  CERTIFICATE  OR THE SHARES
                  HEREBY  EVIDENCED OR ANY INTEREST  THEREIN SHALL BE SUBJECT TO
                  ALL RIGHTS AND OBLIGATIONS OF THE PARTIES TO SUCH STOCK OPTION
                  AGREEMENT AS THEREIN SET FORTH.

                  IT IS  UNLAWFUL  TO  CONSUMMATE  A SALE  OR  TRANSFER  OF THIS
                  SECURITY,   OR  ANY  INTEREST  THEREIN,   OR  TO  RECEIVE  ANY
                  CONSIDERATION  THEREFOR,  WITHOUT THE PRIOR WRITTEN CONSENT OF
                  THE  COMMISSIONER  OF CORPORATIONS OF THE STATE OF CALIFORNIA,
                  EXCEPT AS PERMITTED IN THE COMMISSIONER'S RULES.

         (iv)     Sales of Shares.

                  (a)      Company's  Right of First Refusal.  In the event that
                           the Optionee shall desire to sell, assign or transfer
                           any Shares held by the  Optionee to any other  person
                           (the  "Offered  Shares") and shall be in receipt of a
                           bona  fide  offer  to  purchase  the  Offered  Shares
                           ("Offer"),  the following  procedure shall apply. The
                           Optionee  shall give to the  Company  written  notice
                           containing  the terms and  conditions  of the  Offer,

                           proposed purchaser(s).

                  (b)      An offer  shall not be deemed  bona fide  unless  the
                           Optionee has informed  the  prospective  purchaser of
                           the  Optionee's  obligation  under the Option and the
                           prospective  purchaser  has  agreed to become a party
                           hereunder  and to be bound  hereby.  The  Company  is
                           entitled to take such steps as it reasonably may deem
                           necessary  to  determine  the  validity and bona fide
                           nature of the Offer.

                           ases, then any remaining  Offered Shares may be sold,
                           assigned or  transferred pursuant to the Offer;  pro-
                           vided, that  the Offered   Shares are so  transferred
                           within 30 days of  the expiration  of the thirty (30)
                           day period  to  the person  or  persons named in, and
                           under  the terms  and conditions  of, the  bona  fide

                           provided further, that such persons  agree to execute
                           and deliver to the Company  a written  agreement,  in
                           form and content satisfactory to the Company,  agree-

                  Optionee, the Optionee's personal  representative or any other
                  selling person, as the case may be, prior to the expiration of

                  (a) the  fair  market  value  of the  Shares  to be  purchased
                  determined  in good  faith by the  Board of  Directors  of the
                  Company and (b) the original  exercise  price of the Shares to

registration requirements of federal and state securities laws, which exemptions

exemptions and the suitability of Optionee to acquire the Option and the Shares.

The  representations,  warranties  and agreements of Optionee  contained  herein
shall survive the  execution and delivery of this  Agreement and the exercise of
the Option and the issuance of the Shares.

22. Complete Agreement.  This Agreement constitutes the entire agreement between
the parties with respect to its subject  matter,  and supersedes all other prior
or contemporaneous  agreements and understandings both oral or written; subject,
however,  that in the event of any conflict between this Agreement and the Plan,
the Plan shall govern. This Agreement may only be amended in a writing signed by
the Company and the Optionee.

23. Privileges of Stock Ownership.  Optionee shall not have any of the rights of
a shareholder with respect to any Shares until Optionee exercises the Option and
pays the  Exercise  Price,  Shares are issued and  delivered  to  Optionee,  and
Optionee  is shown as a  shareholder  of record on the books and  records of the
Company.

24. Further Acts. The parties hereto shall cooperate with each other and execute
such additional documents or instruments and perform such further acts as may be
reasonably necessary to affect the purpose and intent of the Agreement.

25. Effect of Headings. The subject headings of the paragraphs and subparagraphs
of this Agreement are included for purposes of  convenience  only, and shall not
affect the construction or interpretation of any of its provisions.

26.  Notices.  Any notice required to be given or delivered to the Company under
the terms of this  Agreement  shall be in writing and addressed to the Corporate
Secretary of the Company at its principal corporate offices. Any notice required
to be given or  delivered  to  Optionee  shall be in writing  and  addressed  to
Optionee at the address  indicated herein or to such other address as such party

(return receipt  requested);  one (1) business day after deposit with any return
receipt express courier (prepaid); or one (1) business day after transmission by
facsimile with a corresponding facsimile transmission confirmation sheet.

27. Counterparts.  This Agreement may be executed  simultaneously in one or more
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together shall  constitute one and the same  instrument.  The exhibits  attached
hereto and  initialed  by the parties  are made a part  hereof and  incorporated
herein by this reference.

28. Parties in Interest. Nothing in this Agreement,  whether express or implied,
is  intended  to  confer  any  rights  or  remedies  under or by  reason of this
Agreement  on any  persons  other than the  parties  to it and their  respective
successors and assigns, nor is anything in this Agreement intended to relieve or
discharge the obligation or liability of any third party to this Agreement,  nor
shall any  provision  give any third person any right of  subrogation  or action
over against any party to this Agreement.

29.  Recovery of Litigation  Costs.  If any legal action or any  arbitration  or
other proceeding is brought for the enforcement of this Agreement, or because of
an alleged dispute,  breach, default or misrepresentation in connection with any
of the  provisions of this  Agreement,  the  successful  or prevailing  party or

                                    13 of 17

<PAGE>

parties shall be entitled to recover as an element of their damages,  reasonable
attorneys'  fees and other  costs  incurred  in that  action or  proceeding,  in
addition to any other relief to which they may be entitled.

30.  Severability;  Construction.  In the  event  that  any  provision  in  this
Agreement shall be invalid or  unenforceable,  such provision shall be severable
from, and such invalidity or unenforceability shall not be construed to have any
effect on, the remaining  provisions of this Agreement.  This Agreement shall be
construed as to its fair meaning and not for or against either party.

31. Survival of Representations and Obligations. All representations, warranties
and agreements of the parties contained in this Agreement, or in any instrument,
certificate,  opinion or other  writing  provided for in it,  shall  survive the
exercise of the Option and the issuance of the Shares.

32.  Specific  Performance.  Each party's  obligations  under this Agreement are
unique. If any party should default in its obligations under this Agreement, the
parties each acknowledge that it would be extremely impracticable to measure the
resulting  damages;  accordingly,  the  nondefaulting  party, in addition to any
other available rights or remedies,  may sue in equity for specific  performance
without the necessity of posting a bond or other security,  and the parties each
expressly waive the defense that a remedy in damages will be adequate.

33.  Gender;  Number.  Whenever  the  context of this  Agreement  requires,  the
masculine gender includes the feminine or neuter gender, and the singular number
includes the plural.

34.  Governing Law and Venue.  This  Agreement will be construed and enforced in
accordance  with, and the rights of the parties will be governed by, the laws of
the State of California without regard to conflict of laws principles.  Venue in
any action arising by reason of this Agreement  shall lie  exclusively in Orange
County, California.

35. Employment  Memorandum of  Understanding.  This Option is issued pursuant to
that certain  Employment  Memorandum of  Understanding  effective May 16th, 2007
between the Optionee and the Company. The terms of the Employment  memorandum of
Understanding  shall  control over any  conflicting  terms in this  Option.  Any
breach under the  Employment  Memorandum  of  Understanding  shall  constitute a
breach  under this  Option and allows the  Company to  terminate  this Option in
whole or in part.

IN WITNESS WHEREOF, this Agreement is made effective on the date first set forth
above at Orange County, California.
