                                  DR. DESIGN, INC.
                             1991 STOCK OPTION PLAN


         1.  DESCRIPTION  OF PLAN.  This is the 1991 Stock  Option  Plan,  dated
August 10, 1991 (the "Plan"), of Dr. Design, Inc., a California corporation (the
"Company").  Under this Plan, certain key employees,  non-employee directors and
consultants  with  important  business  relationships  with the Company,  or any
present or future subsidiary of the Company,  may be granted Options ("Options")
to  purchase  shares of the common  stock of the  Company  ("Common  Stock") . A
person who is granted an Option is referred to as an "Optionee". For purposes of
this Plan,  the term  "subsidiary"  shall have the same  meaning as  "subsidiary
corporation"  as such term is defined in Section 425(f) of the Internal  Revenue
Code of 1986,  as amended  (the  "Code"),  where the  Company  is the  "employer
corporation".  It is  intended  that the  Options  under  this Plan will  either
qualify for treatment as incentive  stock Options under Section 422A of the Code
and be designated  "Qualified  Stock  Options" or not qualify for such treatment
and be designated "Non-Qualified Stock Options."

         2.  PURPOSE OF PLAN.  The purpose of the Plan is to provide  additional
incentives  to certain key  employees and other persons that will enable them to
purchase Common Stock of the Company and thereby share and directly benefit from
the Company's growth,  development and financial success.  In this way, the Plan
will allow the Company to attract and retain key employees and other persons and
encourage them to remain in the Company's service.

         3.  ADMINISTRATION.  The Plan shall be administered by a committee (the
"Committee") to be composed of not less than 2 members of the Board of Directors
of the Company ("Board"),  who are not eligible for selection as Optionees under
the Plan.  Members of the Committee  shall be appointed,  both  initially and as
vacancies occur, by the Board, to serve at the pleasure of the Board. The entire
Board may serve as the Committee, if by the terms of this Plan all Board members
are otherwise  eligible to serve on the Committee.  The Committee  shall meet at
such  times and  places as it  determines,  but at least  once a year  after the
Company's  fiscal year end. A majority of its members shall constitute a quorum,
and the decision of a majority of those present at any meeting at which a quorum
is present shall constitute the decision of the Committee.  A memorandum  signed
by all of its members shall constitute the decision of the Committee without the
necessity of holding an actual meeting.

         The Committee is authorized  and empowered to administer  the Plan and,
subject to the Plan (i) to select the Optionees, to specify the number of shares
of Common Stock with respect to which Options are granted to each  Optionee,  to
specify the Option  Price (as defined in Section 8) and the terms of the Options
and in general to grant  Options;  (ii) to specify  whether the Options  granted
will be for Class A - Voting or Class B - Non-voting  Stock;  (iii) to determine
the dates  upon which  Options  shall be  granted  and the terms and  conditions
thereof in a manner  consistent with this Plan,  which terms and conditions need
not be  identical as to the various  Options  granted;  (iv) to determine  which
Options are to be Qualified Stock Options and Non-Qualified  Stock Options;  (v)
to interpret the Plan;  (vi) to prescribe,  amend and rescind rules  relating to
the Plan;  (vii) to determine the rights and  obligations of Optionees under the
Plan; and (viii) to accelerate the Vesting Schedule and/or the time during which
an  Option  may be  exercised,  notwithstanding  the  provisions  in the  Option
Agreement  (as  defined in Section 7) stating  the time  during  which it may be
exercised.

                                      -1-

         The above matters are not exclusive, and the Committee and/or the Board
shall  have the  authority  to  determine  any  other  matters  incident  to the
administration of this Plan. The Board, and not the Committee, is authorized and
empowered to determine  whether any shares of Common Stock subject to repurchase
by the  Company or its  nominees  as  provided  in  Section 16 will be  actually
repurchased by the Company. The interpretation and construction by the Committee
of any  provision of the Plan or of any Option  granted under it shall be final.
No  member of the  Committee  or the Board  shall be  liable  for any  action or
determination made in good faith with respect to this Plan or any Option granted
under this Plan.

         4. SHARES  SUBJECT TO THE PLAN.  The  aggregate  amount of Common Stock
which may be purchased  pursuant to Options granted under this Plan shall be One
Million  (1,000,000)  shares  of  the  Company's   authorized  but  unissued  or
reacquired  Common  Stock,  subject to  adjustment  as provided in Section 18 to
reflect all stock splits,  stock  dividends or similar capital  changes.  If any
Option shall expire or terminate for any reason without having been exercised in
full,  and/or if the Company  repurchases any shares of Common Stock as provided
herein,  such  unexercised  shares and reacquired  shares shall be available for
granting additional Options under the Plan.

         5. ELIGIBILITY.  The persons who shall be eligible to receive grants of
Qualified  Stock  Options  under  this Plan  shall be the key  employees  of the
Company or any of its  subsidiaries,  and those directors of the Company who are
also key employees,  but who are not members of the  Committee.  The persons who
shall be eligible to receive  grants of  Non-Qualified  Stock Options under this
Plan shall be the key employees of the Company or any of its  subsidiaries,  any
director of the Company,  whether or not he or she is an employee of the Company
(provided that he or she is not a member of the  Committee),  and consultants or
advisers with important  business  relationships with the Company (provided that
substantial  bona fide services  shall have been rendered to the Company by such
advisers or consultants and such services shall not have been in connection with
the offer and sale of securities in a capital raising transaction).

         The Committee  shall have the right in its sole discretion to determine
who is a "key  employee" of the  Company.  The  selection  of Optionees  and the
criteria used to select  Optionees  shall also be within the sole  discretion of
the  Committee.  An Optionee who is granted in writing a leave of absence by the
Board shall be deemed to have remained in the employ of the Company  during such
leave of absence for purposes of this Plan.

         Notwithstanding  the  foregoing,  members  of the  Committee  shall  be
ineligible for selection as participants in the Plan during their service on the
Committee.  More than one Option may be  granted to any one  Optionee.  However,
pursuant to Section  422A(d) of the Code, for Qualified  Stock Options,  no more
than $100,000 of market value Common Stock  (determined  at time of granting the
Option) plus a carryover amount, if applicable, can be granted to an Optionee in
any one calendar  year.  Any portion of an Option that exceeds such amount shall
be treated and deemed a Non-Qualified Stock Option.

         6 . TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for
all  purposes,  be the date when the  Committee  determines  to grant an Option.
Notice of the determination shall be given to each Optionee to whom an Option is
granted within a reasonable time after the date of such grant.

         7.  OPTION  AGREEMENT.  Each  Option  granted  under this Plan shall be
evidenced by a written stock Option agreement ("Option  Agreement")  executed by
the Company and the Optionee.  Each Option Agreement shall,  among other things,
(a) specify the number of shares of Common Stock  granted to an Optionee and the
purchase price per share, (b) designate  whether the Options will be for Class A
- - Voting or

                                      -2-

Class B -  Non-voting  Common  Stock,  (c) contain  each of the  provisions  and
agreements  of this Plan  specifically  required to be  contained  therein,  (d)
indicate   whether  such  Option  is  to  be  a  Qualified  Stock  Option  or  a
Non-Qualified  Stock Option, and if a Qualified Stock Option shall contain terms
and conditions  permitting  such Option to qualify for treatment as an incentive
stock Option under  Section 422A of the Code,  (e) contain the  agreement of the
Optionee  to resell to the  Company  any Common  Stock  issued  pursuant  to the
exercise of Options granted under this Plan pursuant to the Company's repurchase
rights  and/or  rights of first refusal as provided in Sections 16 and 17 below,
(f) specify the Vesting Schedule and Vesting Start Date (as described in Section
9 below), and (g) contain such other terms and conditions as the Committee deems
desirable  and which are not  inconsistent  with this Plan.  The  granting of an
Option or the execution of an Option Agreement shall not require the Optionee to
exercise such Option.

         8.  OPTION  PRICE.  Except as provided in Section 18 or Section 19, the
purchase price per share (the "Option  Price") of Common Stock  underlying  each
Option shall be determined by the  Committee,  but shall not be less than 85% of
the fair market  value of such  shares on the date the Option is  granted.  With
respect to any Qualified  Stock Option,  the Option Price shall not be less than
100% of the fair  market  value of such shares on the date the  Qualified  Stock
Option is granted;  provided,  however,  that if the  Optionee  is a  10-percent
shareholder  of the Company  (as defined in Section  422A(b) (6) of the Code) at
the time such Qualified  Stock Option is granted,  the Option Price shall not be
less  than  110% of the fair  market  value.  The  fair  market  value  shall be
determined in good faith by the Committee or the Board in its sole discretion.

         9. VESTING  REQUIREMENTS.  There shall be a vesting schedule  ("Vesting
Schedule")  for all  Options  granted  under  this  Plan.  The  Committee  shall
determine, in its sole discretion, the Vesting Schedule that shall apply to each
Option  granted  under  this  Plan.  The  Vesting  Schedule  shall be based on a
specified time period,  certain  performance or milestone  goals,  or such other
criteria or factors selected by the Committee in its sole discretion.

         The Vesting  Schedules may differ among the Options  granted under this
Plan;  in  other  words,  the  Committee  shall  have  the  right,  in its  sole
discretion,  to designate  different Vesting Schedules for different  Optionees,
and  different  Vesting  Schedules  for  various  Options  granted  to the  same
Optionee. In addition,  the Committee has the right, in its sole discretion,  to
specify  Vesting  Schedules  for  certain   Optionees   consistent  with  or  to
accommodate vesting commitments that have been previously made and authorized by
the Board  subject to the  adOption of this Plan,  as embodied in the  corporate
minutes and records of the Company.

         The Vesting  Schedule  applied to each Option shall be set forth in the
Option  Agreement.  Each Option  Agreement  shall  specify a Vesting Start Date,
which shall be determined by the Committee in its sole  discretion.  The Vesting
Start  Date is the  beginning  date from  which the  Vesting  Schedule  shall be
calculated.

         The  Vesting  Schedule is  basically  a time  period or other  criteria
during which Options and shares of Common Stock issued to Optionees  shall vest.
An Optionee  shall have the right to exercise all or any portion of an Option at
any time after it is granted.  However, the Vesting Schedule shall determine the
manner in which the  unexercised  portion of an Option  and/or  shares of Common
Stock issued to an Optionee upon exercise of an Option shall vest.

                                      -3-

         The basic purpose of the Vesting Schedule is to determine the rights of
an Optionee and the Company as to Options  and/or  issued shares of Common Stock
upon  an  Optionee's   termination   or  cessation  of  work  for  the  Company.
Specifically,  upon an  Optionee's  termination  or  cessation  of work  for the
Company  as  described  in Section  12 below and in the  Option  Agreement,  the
Vesting  Schedule shall apply as follows:  any unexercised and unvested  Options
shall lapse and be forfeited by the Optionee  upon the  termination  date. As to
any vested  Options,  an Optionee shall have the right to exercise the remaining
unexercised  portion of a vested  Option  during the  applicable  Window  Period
(defined in Section 12 below). With respect to any issued and vested shares held
by an Optionee at the  termination  date, that Optionee cannot sell or otherwise
transfer the vested shares  without first giving the Company the  opportunity to
exercise its Right of First  Refusal under Section 17 of this Plan. In addition,
as to any issued but  unvested  shares held by an  Optionee  at the  termination
date,  the Company shall have the right to repurchase  the unvested  shares from
the Optionee pursuant to Section 16 below.

         For  example,  assume  that an Option  for 1,000  shares is  granted on
October 1, 1991.  The Committee  determines  that the Vesting  Schedule for this
Option  shall be as  follows:  the Option or shares  will fully vest in four (4)
years from the Vesting  Start Date.  The Vesting  Start Date is January 1, 1990,
the date the  Optionee  was  hired by the  Company.  According  to this  Vesting
Schedule,  no portion of an Option or shares  issued  under an Option shall vest
before the one (1) year anniversary of the Vesting Start Date ("Holding Period).
Upon the one (1) year  anniversary  of the Vesting Start Date (or  expiration of
the Holding Period),  twenty-five percent (25%) of the Option or shares shall be
deemed  vested.  Thereafter,  the  Option or shares  shall  vest at  twenty-five
percent (25%) for every  subsequent  year. In addition,  after the first year, a
pro rata portion of the annual twenty-five percent (25%) vesting shall be deemed
to vest each month.

         Under the above  example,  on October 1, 1991,  the date the Option was
granted,  the  Optionee  may  exercise all or any portion of the Option since an
Optionee has the right to purchase  any shares  under an Option at any time.  An
Optionee's  ability to  exercise  an Option is not  conditioned  on whether  the
Option is vested or nonvested.  Assume that Optionee purchases two hundred fifty
(250)  shares  under the Option in 1991,  and is  terminated  by the  Company on
December 31, 1992. On December 31, 1992,  only fifty percent (50%) of the Option
or shares shall be deemed vested,  since twenty-five  percent (25%) vested as of
January 1, 1991 (the expiration of the Holding Period),  and twenty-five percent
(25%) vested for the year 1991.

         As a result, upon such termination,  the two hundred fifty (250) shares
previously  purchased and issued to Optionee are vested  shares,  subject to the
Company's  Right of First Refusal in the event Optionee  proposes to transfer or
sell such shares.  Since fifty percent (50%) or five hundred (500) shares of the
Option are deemed vested as of the termination date, and two hundred fifty (250)
shares have already  been  issued,  Optionee has the right during the sixty (60)
day Window  Period  specified  in  Section  12(b) of this Plan to  purchase  the
remaining two hundred fifty (250) vested  shares.  If Optionee does not purchase
the vested portion of the Option (250 shares) within the Window Period, then the
Option shall automatically terminate upon the expiration of the Window Period.

         Using the same example above,  assume that Optionee had purchased seven
hundred fifty (750) shares under the Option before he/she was terminated.  Since
only fifty  percent  (50%) or five hundred (500) shares will be deemed vested as
of the termination date, five hundred (500) of the issued shares shall be vested
and two hundred  fifty (250) of the issued shares shall be  non-vested.  In such
event,  the Company  has the right to  repurchase  the two  hundred  fifty (250)
unvested shares at the Option Price pursuant to Section 16 of this Plan, and the
other five  hundred  (500)  vested  shares may be  transferred  by the  Optionee
subject to the  Company's  Right of First Refusal under Section 17 of this Plan.
Since  there is no  remaining  unexercised  portion of the Option that is deemed
vested as of the  termination  date,  Optionee may not  purchase any  additional
shares during a Window Period or after termination.

                                      -4-

         The above examples are only for informational purposes. The application
of each Option will depend upon the specific  provisions of the Vesting Schedule
for each Option.

         10. EXERCISE OF OPTIONS.  Subject to all other provisions of this Plan,
each Option shall be  exercisable  for the full number of shares of Common Stock
specified in the grant and in the Option Agreement,  or any part thereof, at any
time after the Option is granted.  However,  an Optionee  shall not exercise any
Option,  or part thereof,  more frequently than once per calendar  quarter;  the
preceding limitation shall not apply if the Common Stock becomes publicly traded
upon an initial  public  offering of its  securities  pursuant to a registration
statement filed by the Company under the Securities Act of 1933, as amended.

         No Option can be exercised  after its  termination  date or after it is
terminated  pursuant to Section 12. Each Option shall terminate and expire,  and
shall no longer be  subject to  exercise,  as the  Committee  may  determine  in
granting such Option,  but in no event later than ten (10)  calendar  years from
the date the Option is granted.  An Option can be exercised only by the Optionee
to whom it is granted during his/her  lifetime.  After the death of an Optionee,
the vested portion of the Option may be exercised,  prior to its  termination as
provided in Section 12 below, only by his/her legal  representative,  legatee or
heir who acquired the right to exercise the Option.

         11. METHOD OF EXERCISING  OPTIONS.  An Option shall be exercised by the
Optionee by delivering to the Company  before the Option expires or terminates a
written notice  specifying the number of shares to be purchased.  The Optionee's
written  notice must be  accompanied by (a) payment of the full Option Price for
the number of shares to be  purchased  in cash,  by check or such  other  lawful
consideration  (including promissory notes or the assignment and transfer by the
Optionee to the Company of outstanding shares of Common Stock previously held by
the Optionee in a manner  intended to comply with the  provisions  of Rule 16b-3
under the  Securities  and Exchange Act of 1934) as the Committee may approve in
its sole  discretion,  (b) upon  the  Company's  request,  a letter  or  written
statement  from the  Optionee in form and  substance  acceptable  to the Company
setting forth the investment intent and other  representations  of the Optionee,
and (c) upon the Company's  request,  payment in cash or check of any taxes that
the Company is required to withhold or collect as further  discussed  in Section
21.

         12.   TERMINATION  OF  OPTIONS.   Any  portion  of  an Option  that has
vested pursuant to the terms of an Option Agreement shall immediately  terminate
upon the first to occur of any of the following events:

               (a)   the expiration or termination date  specified in the Option
Agreement;

               (b)   the expiration of  sixty  (60)  days  from  the  date of an
Optionee's  termination or  resignation  of employment or voluntary  leaving the
employ  of the  Company  ("Window  Period")  (other  than by  reason of death or
disability),  except if the Optionee is  terminated  for "Cause',  as defined in
Section 16 of this Plan, then the Option terminates upon the termination date;

               (c)  the  expiration  of six  (6)  months  from  the  date  of an
Optionee's termination or other cessation of employment ("Window Period") due to
that Optionee having become  disabled within the meaning of Section  22(e)(3) of
the Code;

               (d)  the expiration  of twelve  (12)  months  from the date of an
Optionee's death ("Window  Period") if his/her death occurs while being employed
with the Company;

               (e)  for  Options  granted to consultants or other  non-employees
who become  members of the Board,  if the  Optionee is no longer a member of the
Board;

                                      -5-

               (f) for  Options  granted to  consultants  or third  parties  who
perform  substantial bona fide services to the Company,  if the Optionee has not
provided  services to the Company as an  independent  contractor,  consultant or
advisor for a period of time  determined  by the Committee or the Board in their
sole discretion, at the time of granting the Option; and/or

               (g)      the termination of an Option pursuant to Section 18.

         In addition to the above  events,  all  Qualified  Stock  Options shall
terminate  no later than ten (10) years from the date the Option is granted,  or
no later than five (5) years from the date the  Option is  granted  for  Options
granted to Optionees who own more than ten percent  (10%) of the total  combined
voting  power of all  classes of the  Company's  stock at the time the Option is
granted (as defined in Section 422A(b)(6) of the Code).

         Upon  the  termination  of an  Optionee  for any  reason  or  upon  the
happening  of any of the events in  subparagraphs  (e),  (f) or (g)  above,  all
unexercised  and unvested  portions of an Option shall  automatically  lapse and
shall not be entitled to be exercised at any further time. All  unexercised  and
vested Options, or parts thereof,  that are not exercised during a Window Period
or prior to  termination as provided above shall be forfeited by an Optionee and
shall not be exercised after the Window Period or termination  date, as the case
may be. Upon such  termination,  all issued but unvested  shares of Common Stock
owned by an Optionee shall be subject to being repurchased by the Company at the
Option  Price  pursuant  to  Section  16 of this Plan.  In  addition,  upon such
termination,  all issued and vested  shares of Common Stock owned by an Optionee
shall only be  subject  to the  Company's  Right of First  Refusal  set forth in
Section 17 of this Plan.

         13. ADDITIONAL REQUIREMENTS FOR QUALIFIED STOCK OPTIONS. Subject to the
other  provisions of this Plan,  all Optionees who are granted  Qualified  Stock
Options must satisfy all the following  requirements in order to receive the tax
benefits of an incentive stock Option under the Code:

               (a) the  Optionee  must be  continuously  employed by the Company
from the time the Option is granted until at least three (3) months before it is
exercised  (twelve (12) months if the Optionee is disabled within the meaning of
Section 22(e)(3) of the Code);

               (b) the  Optionee  must hold the Common  Stock until at least two
(2) years  after the Option is granted  and one (1) year after it is  exercised;
and

               (c) the Optionee cannot exercise a current Qualified Stock Option
while there is outstanding  another  Qualified  Stock Option that was previously
granted to the Optionee that has not been fully exercised.

         A Qualified Stock Option issued to an Optionee who fails to meet all of
the three (3)  requirements  above is  subject to being  treated  and taxed as a
Non-Qualified Stock Option.

         14. ISSUANCE OF COMMON STOCK.  Notwithstanding anything to the contrary
contained  herein,  the Company shall not be obligated to grant any Option under
this Plan or to sell or issue any Common Stock  pursuant to any Option or Option
Agreement,  unless the grant or sale is effectively registered or qualified,  or
exempt from  registration  or  qualification  under all applicable  state and/or
federal laws or rulings and  regulations of any  governmental  regulatory  body.
Prior to the  execution  of an Option  Agreement  and/or  issuance of the Common
Stock, the Company shall have the right to require an Optionee to deliver to the
Company written investment  representations or other warranties deemed necessary
or advisable  by the Company to comply with the  requirements  of any  exemption
from such registration or other qualification of such shares.

                                      -6-

         The  required   representations  and  warranties  may  include  without
limitation  representations  and agreements that each Optionee (a) is purchasing
such shares for investment and for his/her own account, and not with any present
intention  of  selling  or  otherwise  disposing  of  such  shares;  (b)  has  a
pre-existing  personal or business relationship with the Company or its officers
or directors, or has sufficient business or financial experience to evaluate the
risks  involved  in  purchasing  the Common  Stock;  (c) agrees to have a legend
placed upon the face or reverse of any certificates  evidencing such shares that
restrict the transfer of such shares; and/or (d) agrees to such other matters as
the Company requires or deems advisable.

         15.  NONTRANSFERABILITY.   Unless  otherwise  provided  in  the  Option
Agreement,  an Optionee shall not sell, assign,  encumber,  transfer or permit a
levy or  attachment  on all or any part of his/her  Qualified  Stock  Options or
Non-Qualified  Stock  Options  and/or  any  shares  of  Common  Stock  purchased
thereunder  to any person or entity at any time.  The Option  Agreement  may, in
some instances,  provide that certain Options granted hereunder and/or shares of
Common Stock previously issued to Optionee may be transferable by will or by the
laws of  descent  and  distribution  upon the death of an  Optionee/shareholder,
and/or any Non-Qualified Stock Options may be transferable or assignable subject
to the  Company's  Right of First  Refusal to purchase the Common Stock prior to
such transfer or assignment as provided in Section 17 below.

         The Option  Agreement may also provide that an Optionee or  shareholder
holding  Non-Qualified  Stock Options or shares of Common Stock  purchased under
Non-Qualified Stock Options may have the right, with prior written notice to the
Company, to transfer or assign such Options or shares of Common Stock to his/her
spouse, children or a living trust for the benefit of their family, provided the
Optionee/shareholder  or his or her spouse is the sole  trustee of the trust and
the sole  beneficiaries of the trust shall be the  Optionee/shareholder,  his or
her spouse and/or their children,  and further provided that any such transferee
shall  agree in writing to be bound by all the  provisions  of this Plan and the
Option  Agreement  as a condition  precedent  to the transfer and receipt of the
shares of Common Stock. In addition,  in the event the Company's Common Stock is
publicly traded,  there will be additional  restrictions  imposed on the sale or
transfer of Common  Stock  pursuant to Rule 144 of the  Securities  and Exchange
Commission and other applicable laws, rules or regulations.

         16.  REPURCHASE  OF STOCK.  Upon the  termination  of an Optionee as an
employee,  independent  contractor  or consultant of the Company for "Cause" (as
defined  below),  the Company and its assignees  shall have the right,  in their
sole discretion,  to repurchase  ("Repurchase  Right") some or all of any vested
and/or  unvested  shares of Common Stock  previously  issued to an Optionee upon
exercise  of any Option  ("Repurchase  Shares").  Pursuant to Section 12 of this
Plan,  all  unexercised  portions  of an  Option,  vested or  non-vested,  shall
automatically  lapse upon  termination  of an Optionee for "Cause".  The Company
shall  exercise its  Repurchase  Right within sixty (60) days after the date the
Optionee is  terminated  for "Cause" by paying to the Optionee in cash an amount
per share equal to the Option Price.

         In  addition to the above the  Repurchase  Right upon  termination  for
"Cause", the Company shall also have a repurchase right as to all or any portion
of issued shares that are unvested as of the  termination  date. In other words,
if an Optionee is  terminated  or ceases to work for the Company for any reason,
and has previously  purchased  shares of Common Stock that have not vested as of
the  termination  date,  then the  Company  shall  have the right to  repurchase
("Repurchase  Right")  some or all of the issued and  unvested  shares of Common
Stock  ("Unvested  Shares") at the Option Price.  The Company shall exercise its
Repurchase  Right for the  Unvested  Shares  within  sixty  (60) days  after the
termination  date by paying to the Optionee in cash an amount per share equal to
the Option Price.

                                      -7-


         Upon termination for "Cause", or other termination whereby Optionee has
Unvested  Shares,  the Optionee  shall  surrender and deliver to the Company the
stock  certificates for the Repurchase Shares and the Unvested Shares.  Any new,
substituted or additional  securities or other property distributed with respect
to the  Repurchase  Shares or  Unvested  Shares as a result of any stock  split,
recapitalization  or adjustment under Section 18 below shall also be held by the
Company until it decides whether to exercise its Repurchase  Right.  Any regular
cash  dividends  on the  Repurchase  Shares  or  Unvested  Shares  shall be paid
directly to the Optionee and shall not be held by the  Company.  The  Repurchase
Shares  or  Unvested  Shares  and any  other  assets  or  securities  associated
therewith  shall be  released to and  retained by the Company and its  assignees
upon exercise of the Repurchase Right, or shall be released to the Optionee upon
expiration  of the sixty (60) day period if the  Company has not  exercised  its
Repurchase Right as to all of the Repurchase Shares or Unvested Shares.

         The Company shall  exercise its  Repurchase  Right by delivering to the
Optionee a written notice and paying the Option Price for the Repurchase  Shares
or Unvested  Shares  within the sixty (60) day period.  In the event the Company
does not exercise its  Repurchase  Right as provided  herein,  or exercises  its
Repurchase  Right as to some but not all of the  Repurchase  Shares or  Unvested
Shares,  the remaining  Repurchase  Shares and/or Unvested Shares shall still be
subject to the Company's  Right of First Refusal  pursuant to Section 17 of this
Plan.

         The term "Cause" shall mean (a) willful  misconduct,  gross negligence,
theft, fraud or embezzlement; (b) alcoholism or illegal drug addiction, that the
Board or Committee has reasonably determined causes the Optionee to be unable to
perform  his/her  duties and  responsibilities  for the Company;  and/or (c) the
unauthorized use,  disclosure or  misappropriation,  or attempt thereof,  of any
confidential  information  or trade  secrets of the  Company  or any  subsidiary
thereof.

         17.  RIGHT OF FIRST  REFUSAL.  The Company  shall have a right of first
refusal  over all  Options  and all Common  Stock  issued  upon the  exercise of
Options ("Right of First  Refusal").  If an Optionee desires at any time to sell
or otherwise transfer all or any part of vested Options, vested shares of Common
Stock  previously  issued to Optionee,  and/or  Unvested Shares that the Company
does not elect to repurchase under Section 16, as the case may be, then prior to
any such sale or  transfer,  the  Optionee  shall give the  Company the right to
purchase  the vested  Options,  the  vested  shares of Common  Stock  and/or the
Unvested  Shares that have not been  repurchased  pursuant to the same terms and
conditions  specified in a bona fide written  offer from a third party or entity
that wishes to purchase the same from  Optionee.  The Company shall exercise its
Right of First Refusal pursuant to the terms contained in the Option  Agreement.
The Company's  Right of First Refusal shall  terminate upon the  consummation of
the sale of securities pursuant to a registration statement filed by the Company
under the  Securities  Act of 1933, as amended,  in  connection  with an initial
underwritten offering of its securities to the general public.

         18. RECAPITALIZATION,  REORGANIZATION, MERGER OR CONSOLIDATION. Subject
to any required  shareholder  action or approval,  if the outstanding  shares of
Common Stock of the Company are increased,  decreased or exchanged for different
securities through a reorganization,  merger,  consolidation,  recapitalization,
reclassification,  stock split,  stock  dividend or like capital  adjustment,  a
proportionate  adjustment shall be made (a) in the aggregate number of shares of
Common  Stock  which may be  purchased  pursuant  to the  exercise of Options as
provided in Section 4 hereof,  and (b) in the number,  price, and kind of shares
subject to any  outstanding  Option  granted  under  this  Plan.  Subject to any
required  shareholder  action  or  approval,  if the  Company  is the  surviving
corporation  in any  merger or  consolidation,  each  outstanding  Option  shall
survive and is exercisable pursuant to the terms of this Plan.

                                      -8-

         Upon  the  dissolution  or  liquidation  of the  Company  or  upon  any
reorganization,  merger or  consolidation in which the Company does not survive,
this Plan and each outstanding  Option shall terminate  subject to the following
provisions.  In such event:  (a) each  Optionee who is not tendered an Option by
the surviving  corporation in accordance  with all of the terms of provision (b)
immediately below or who does not accept any such substituted Option which is so
tendered,  shall have the right until 30 days before the effective  date of such
dissolution,  liquidation,  reorganization, merger or consolidation in which the
Company is not the surviving corporation,  to exercise, in whole or in part, any
unexpired and vested  Option or Options  issued to him/her which the Optionee is
then  capable of  exercising  pursuant  to the  provisions  of the Option and of
Sections 10 and 11 above;  provided,  however, that should the Board so elect in
its sole and absolute  discretion  all  Optionees  may be given upon at least 30
days  notice  (x) the Option to  exercise,  in whole or in part,  any  unexpired
Option,  without  regard  to the  Vesting  Schedule  requirements  if the  Board
accelerates  the vesting  period,  or (y) the Option to surrender such Option or
Options to the Company for a price (which may be payable, in the sole discretion
of the Committee, in cash or in securities of the Company or in a combination of
both,  and at times or in  installments  determined  by the  Company in its sole
discretion),  equal to the difference  between the aggregate Option Price of the
Option or Options without regard to the installment provisions and the aggregate
fair market value (as  determined in the manner  provided in Section 8 above) of
the  shares  subject  to such  Option or  Options on the date one day before the
effective  date of such  dissolution,  liquidation,  reorganization,  merger  or
consolidation;  or (b)  upon at least 30 days  notice  in its sole and  absolute
discretion, the surviving corporation may, but shall not be so obligated, tender
to any  Optionee  an Option  or  Options  to  purchase  shares of the  surviving
corporation,  and such new  Option  or  Options  shall  contain  such  terms and
provisions  as shall be  required  to  substantially  preserve  the  rights  and
benefits of any Option then outstanding under the Plan.

         To the  extent  that  the  foregoing  adjustments  relate  to  stock or
securities of the Company,  such adjustments  shall be made by the Board,  whose
determination  in that respect  shall be final,  binding and  conclusive.  There
shall be no  pre-emptive  rights  regarding  the Common  Stock  and/or any other
privileges  granting  to  Optionees/shareholders  the  right to  maintain  their
percentage  ownership in the Company upon the issuance of  additional  shares of
Common Stock or any other change in capital structure. In other words, except as
expressly provided above in this Section 18, an Optionee shall have no rights by
reason of any  subdivision or  consolidation  of shares of stock of any class or
the  payment of any stock  dividend  or any other  increase  or  decrease in the
number  of shares of stock of any  class,  and the  number or price of shares of
Common Stock  subject to any Option shall not be affected by, and no  adjustment
shall be made by reason of, any dissolution, liquidation, reorganization, merger
or  consolidation,  or any  issuance  by the  Company  of shares of stock of any
class,  or rights to purchase or subscribe for stock of any class, or securities
convertible into shares of stock of any class.

         The grant of an Option  under this Plan shall not affect in any way the
right or power of the Company to make adjustments,  reclassifications or changes
in its  capital  or  business  structures  or to merge,  consolidate,  dissolve,
liquidate, sell or transfer all or any part of its business or assets.

         19.  SUBSTITUTE  OPTIONS.  If the Company at any time should succeed to
the  business  of  another  corporation  through a merger or  consolidation,  or
through the acquisition or stock or assets of such  corporation,  Options may be
granted  under  this  Plan  to  Option  holders  of  such   corporation  or  its
subsidiaries,  in substitution for Options to purchase stock of such corporation
held by them at the time of  succession.  The  Board,  in its sole and  absolute
discretion, shall determine the extent to which such substitute Options shall be
granted (if at all),  the person or persons to receive such  substitute  Options
(who need not be all Option holders of such corporation),  the number of Options
to be received by each such person,  the Option Price of such Option  (which may
be determined  without  regard to Section 8 hereof) and the terms and conditions
of such substitute Options.

                                      -9-


         Provided,  however,  that the  Option  Price of each  such  substituted
Option which is a Qualified  Stock  Option shall be an amount such that,  in the
sole and absolute  judgment of the Board (and in compliance  with Section 425(a)
of the Code),  the economic  benefit provided by such Option is not greater than
the economic benefit represented by the Option in the acquired corporation as of
the  date of the  Company's  acquisition  of such  corporation.  Notwithstanding
anything to the  contrary  herein,  no Option  shall be granted,  nor any action
taken, permitted or omitted, which would cause this Plan, or any Options granted
hereunder as to which Rule 16b-3 under the  Securities  Exchange Act of 1934, as
amended, may apply, not to comply with such Rule.

         20.  RIGHTS AS A  SHAREHOLDER.  An  Optionee  shall have no rights as a
shareholder of the Company with respect to any shares covered by an Option until
the  Option  Price is fully  paid for the  shares  that are  exercised  under an
Option.  Within  thirty  (30) days of receipt of the Option  Price,  the Company
shall issue and deliver to the  Optionee  the stock  certificate  for the shares
purchased. No adjustment shall be made for dividends (ordinary or extraordinary,
whether in cash,  securities or other property) or distributions or other rights
for which the record  date is prior to the date the Option  Price is received by
the Company, except as expressly provided in Section 18.

         21.  WITHHOLDING OF TAXES. The Company or any applicable  subsidiary or
parent may deduct and  withhold  from the wages,  salary,  bonus or other income
paid by the Company or such  subsidiary  or parent to the Optionee the requisite
tax upon the amount of taxable income, if any, recognized by the Optionee due to
the  exercise  of any part of an Option or the  permitted  sale of Common  Stock
issued to an Optionee  under this Plan, all as may be required from time to time
under any federal or state tax laws and  regulations.  This  withholding  of tax
shall be made from the Company's (or such  subsidiary's or parent's)  concurrent
or next  payment of wages,  salary,  bonus or other income to the Optionee or by
payment to the Company  (or such  subsidiary  or parent) by the  Optionee of the
required withholding tax, as determined by the Committee.

         22. EFFECTIVENESS AND TERMINATION OF PLAN. This Plan shall be effective
on the date set forth on Page 1 above ("Effective  Date") since that is the date
when this Plan was adopted by the Board and approved by the  shareholders of the
Company.  No Option shall be granted under this Plan on or after that date which
is ten (10) years from the Effective  Date.  This Plan shall  terminate when all
shares of Common Stock which may be issued  hereunder have been so issued or ten
(10) years from the Effective Date,  whichever is earlier.  The Board,  however,
may in its sole discretion terminate this Plan at any time. No such termination,
other  than  as  provided  for in  Section  18,  shall  in any  way  affect  any
outstanding Option.

         23.  AMENDMENT  OF PLAN.  The Board  shall have the right to amend this
Plan in its sole discretion,  subject to approval of the shareholders.  With the
consent of each Optionee  affected,  the Board may also make such changes in the
terms and conditions of granted Options as it deems  advisable.  Such amendments
and changes shall include without  limitation  acceleration of the time at which
an Option may be vested.

         The Board,  however,  may not, without the approval of the shareholders
(a) increase the maximum  number of shares  subject to Qualified  Stock Options,
except  pursuant  to Section  18, (b)  decrease  the  Option  Price  requirement
contained  in Section 8 (except as  contemplated  by Section 19), (c) change the
designation  of the class of  employees  eligible  to  receive  Qualified  Stock
Options,  (d) modify the  limits set forth in Section 5  regarding  the value of
Common  Stock for which any  Optionee may be granted  Qualified  Stock  Options,
unless the provisions of Section 422A(d) of the Code are likewise  modified,  or
(e) in any manner  materially  increase  the benefits  accruing to  participants
under this Plan,  or  otherwise  modify this Plan such that it fails to meet the
requirements  of Rule 16b-3 of the  Securities  and Exchange  Commission for the
exemption of the acquisition,  cancellation,  expiration or surrender of Options
from the operation of Section 16(b) of the Securities Exchange Act of 1934.

                                      -10-

         24. NOT AN EMPLOYMENT  AGREEMENT.  Nothing contained in this Plan or in
any Option Agreement shall confer on any Optionee any guaranty,  right or vested
interest to be continued in the employ of the Company or one of its subsidiaries
or limit the ability of the  Company or any of its  subsidiaries  to  terminate,
with or without cause, in its sole discretion, the employment of any Optionee.

         25.   GOVERNING LAW. This Plan and any Option granted  pursuant to this
Plan shall be construed and enforced under the laws of the State of California.

         26.  ARBITRATION.  All  Optionees,  shareholders  and the Company shall
attempt to resolve any dispute regarding this Plan in an amicable  fashion.  Any
unresolved  disputes regarding this Plan or the administration  thereof shall be
submitted to binding  arbitration in San Diego,  California,  to be conducted in
accordance with the rules of the American Arbitration Association ("AAA").

         Any dispute shall be submitted to an  arbitration  panel  consisting of
three (3)  members,  one of whom shall be selected by the  Company,  one of whom
shall be selected by the Optionee/shareholder, and one of whom shall be selected
by the other two arbitrators.  All arbitrators must have at least five (5) years
experience  in  the  computer  electronic  industry  and/or  the  legal  aspects
pertaining  to such  industry.  The parties  shall be entitled to all rights and
privileges to conduct discovery (i.e. interrogatories,  production of documents,
depositions,  exchange  of  witnesses,  and  subpoenas),  the right to have oral
testimony  at the  arbitration  hearing,  and other  rights as  provided  in the
California  Code  of  Civil  Procedure.   After  discovery  is  concluded,   the
arbitrators  shall  hold a  hearing  in  accordance  with  the  AAA  rules.  The
arbitration  shall be governed under  California law. The decision of a majority
of the arbitrators shall control. The order or award of the arbitrators shall be
final  and  shall be  enforced  in any  court  of  competent  jurisdiction.  The
prevailing party in the arbitration  shall be entitled to recover from the other
party its attorney's fees and costs incurred.

         27.   APPLICATION  OF FUNDS.   The  proceeds  received  by the  Company
from the sale of Common Stock  pursuant to Options may be used for any corporate
purpose. The Board shall determine, in its sole discretion,  how to use or apply
such funds or proceeds.


         28.   ENTIRE  PLAN.  This  is  the  entire  Stock  Option  Plan of  the
Company and supersedes all prior or contemporaneous discussions, representations
or agreements,  whether oral or written. This Plan cannot be modified or amended
except by the Board and/or the shareholders as provided above.

         29.  VALIDITY.  If any  provision  of this  Plan is held by a court  of
competent  jurisdiction  to be invalid,  void or  unenforceable,  the  remaining
provisions  shall  remain in full force and effect,  and the invalid  provisions
shall be revised to reflect  the intent of the  Company  regarding  the  subject
matter thereof.
