 4. Administration of the Plan.

          (a)     Procedure.

                           (i)Multiple Administrative Bodies. The Plan may be 
administered by different Committees with respect to different groups of 
Employeesand Consultants.

                           (ii)Section 162(m). To the extent that the 
Administrator determines it to be desirable to qualify Options granted hereunder
as "performance-based compensation"  within the meaning of Section  162(m) of 
the Code, the Plan shall be administered  by a Committee of two or more "outside
directors"  within the meaning of Section 162(m) of the Code.

                           (iii)Rule 16b-3.  To the extent desirable to qualify 
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under 
Rule 16b-3.

          (b) Powers of the Administrator. Subject to the provisions of the Plan
and in the case of a Committee,  the specific  duties  delegated by the Board to
such Committee, the Administrator shall have the authority, in its discretion:

                           (i)to determine the Fair Market Value of the Common 
Stock, in accordance with Section 2(k) of the Plan;

                           (ii)to select the officers, Consultants and Employees
to whom Options may from time to time be granted hereunder;

                           (iii)to determine whether and to what extent Options 
are granted hereunder;

                           (iv)to determine the number of shares of Common Stock
to be covered by each such award granted hereunder;

                           (v)to approve forms of agreement for use under the 
Plan;

                           (vi)to determine the terms and conditions, not 
inconsistent with the terms of the Plan, of any award granted hereunder 
(including, but not limited to, the share price and any  restriction or  
limitation,  or any vesting acceleration or waiver of forfeiture  restrictions
regarding any Option and/or the shares of Common Stock relating  thereto, based
in each case on such factors as the Administrator shall determine, in its sole 
discretion);

                           (vii)to    determine    whether    and   under   what
circumstances  an Option may be settled in cash under subsection 9(e) instead of
Common Stock;

                           (viii) to determine whether, to what extent and under
what circumstances Common Stock and other amounts  payable  with  respect to an 
award  under  this Plan shall be  deferred either automatically or at the 
election of the participant  (including providing for and determining  the 
amount,  if any, of any deemed earnings on any deferred amount during any 
deferral period);

                           (ix)to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was 
granted; and

          (c) Effect of Administrator's Decision. All decisions,  determinations
and  interpretations  of the  Administrator  shall be final and  binding  on all
Optionees and any other holders of any Options.

          (d) Grant Limits.  The following  limitations shall apply to grants of
Options under the Plan:

                                       23


                         (i) No employee shall be granted,  in any fiscal year 
of the Company,  Options under the Plan to purchase more than 150,000 Shares,   
provided that the Company may make an additional  one-time  grant of up to 
250,000 Shares to newly-hired Employees.

                         (ii) The foregoing  limitations   shall   be   adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11.

                         (iii) If an Option is cancelled (other than in 
connection with a transaction  described in Section 11), the  cancelled  Option 
shall be counted against  the limits  set forth in  Section  4(d)(i).  For this 
purpose,  if the exercise  price of an Option is reduced,  the  transaction  
will be treated as a cancellation of the Option and the grant of a new Option.

 5.       Eligibility.

          (a)  Nonstatutory  Stock  Options  may be granted  only to  Employees,
Directors,  and  Consultants.  Incentive  Stock  Options may be granted  only to
Employees.  An Employee,  Director, or Consultant who has been granted an Option
may, if he is otherwise eligible, be granted an additional Option or Options.

          (b) Each Option shall be designated in the written option agreement as
either an  Incentive  Stock  Option or a  Nonstatutory  Stock  Option.  However,
notwithstanding such designations,  to the extent that the aggregate Fair Market
Value of the Shares with respect to which Options  designated as Incentive Stock
Options are  exercisable  for the first time by any Optionee during any calendar
year  (under  all plans of the  Company  or any  Parent or  Subsidiary)  exceeds
$100,000, such excess Options shall be treated as Nonstatutory Stock Options.

          (c) For purposes of Section  5(b),  Incentive  Stock  Options shall be
taken into account in the order in which they were granted,  and the Fair Market
Value of the Shares shall be  determined  as of the time the Option with respect
to such Shares is granted.

          (d) The Plan shall not confer upon any Optionee any right with respect
to continuation of employment or consulting  relationship with the Company,  nor
shall it interfere in any way with his right or the Company's right to terminate
his employment or consulting relationship at any time, with or without cause.

 6. Term of Plan.  The Plan shall become  effective upon the earlier to occur of
its adoption by the Board of Directors  or its approval by the  shareholders  of
the Company as described in Section 18 of the Plan. It shall  continue in effect
for a term of ten (10) years unless  sooner  terminated  under Section 14 of the
Plan.

 7. Term of  Option.  The term of each  Option  shall be ten (10) years from the
date of grant  thereof or such  shorter  term as may be  provided  in the Option
Agreement.  However,  in the case of an  Incentive  Stock  Option  granted to an
Optionee who, at the time the Option is granted,  owns stock  representing  more
than ten  percent  (10%) of the  voting  power  of all  classes  of stock of the
Company or any Parent or  Subsidiary,  the term of the Option  shall be five (5)
years from the date of grant  thereof or such shorter term as may be provided in
the Option Agreement.

 8.       Exercise Price and Consideration.

          (a) The per Share exercise price for the Shares to be issued  pursuant
to exercise of an Option shall be such price as is determined by the Board,  but
shall be subject to the following:

                                       24


                            (i)In the case of an Incentive Stock Option

                             (A) granted to an Employee  who, at the time of the
grant of such Incentive Stock Option, owns stock  representing  more than ten 
percent (10%) of the voting power of all classes  of stock of the  Company  or 
any  Parent or  Subsidiary, the per Share exercise  price shall be no less than 
110% of the Fair Market Value per Share on the date of grant.

                             (B)granted to any Employee, the per Share exercise 
price shall be no less than 100% of the Fair Market Value per Share on the date 
of grant.

                           (ii)In the case of a Nonstatutory Stock Option, the 
per Share exercise price shall be determined by the Administrator.  In the case
of a  Nonstatutory  Stock  Option  intended  to  qualify  as  "performance-based
compensation"  within the meaning of Section  162(m) of the Code,  the per Share
exercise  price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                           (iii) Notwithstanding the foregoing, Options may be
granted with a per Share exercise price of less than 100% of the Fair Market 
Value per Share on the date of grant pursuant to a merger or other corporate 
transaction.

          (b) The  consideration  to be paid for the  Shares to be  issued  upon
exercise of an Option,  including the method of payment,  shall be determined by
the  Administrator  and  may  consist  entirely  of (1)  cash,  (2)  check,  (3)
promissory  note,  (4) other  Shares  which (x)  either  have been  owned by the
Optionee for more than six months on the date of surrender or were not acquired,
directly or  indirectly,  from the Company,  and (y) have a Fair Market Value on
the date of surrender equal to the aggregate  exercise price of the Shares as to
which said Option  shall be  exercised,  (5)  authorization  from the Company to
retain from the total number of Shares as to which the Option is exercised  that
number of Shares having a Fair Market Value on the date of exercise equal to the
exercise  price  for the  total  number  of  Shares  as to which  the  Option is
exercised,  (6) delivery of a properly  executed  exercise  notice together with
irrevocable  instructions  to a broker to  promptly  deliver to the  Company the
amount of sale or loan proceeds required to pay the exercise price, (7) delivery
of an  irrevocable  subscription  agreement  for the  Shares  which  irrevocably
obligates  the option holder to take and pay for the Shares not more than twelve
months  after  the  date of  delivery  of the  subscription  agreement,  (8) any
combination of the foregoing methods of payment, (9) or such other consideration
and method of payment for the issuance of Shares to the extent  permitted  under
Applicable Laws. In making its  determination as to the type of consideration to
accept,  the Board shall  consider if  acceptance of such  consideration  may be
reasonably expected to benefit the Company.

 9. Exercise of Option.

          (a)  Procedure  for  Exercise;  Rights as a  Shareholder.  Any  Option
granted  hereunder  shall be exercisable at such times and under such conditions
as determined by the Board,  including  performance criteria with respect to the
Company and/or the Optionee,  and as shall be permissible under the terms of the
Plan.

                  An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed to be exercised  when written notice
of such exercise has been given to the Company in  accordance  with the terms of
the Option by the person  entitled to exercise  the Option and full  payment for
the Shares with  respect to which the Option is exercised  has been  received by
the  Company.  Full  payment  may, as  authorized  by the Board,  consist of any
consideration  and method of payment  allowable  under Section 8(b) of the Plan.
Until the issuance (as  evidenced by the  appropriate  entry on the books of the
Company or of a duly  authorized  transfer  agent of the  Company)  of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any


                                       25


other rights as a  shareholder  shall exist with respect to the Optioned  Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued)  such stock  certificate  promptly  upon  exercise of the Option.  No
adjustment  will be made for a dividend or other right for which the record date
is prior to the date the stock  certificate  is issued,  except as  provided  in
Section 11 of the Plan.

                  Exercise of an Option in any manner shall result in a decrease
in the number of Shares which thereafter may be available,  both for purposes of
the Plan and for sale under the Option,  by the number of Shares as to which the
Option is exercised.

          (b)  Termination of Status as an Employee or Consultant.  In the event
of termination of an Optionee's  Continuous  Status as an Employee or Consultant
(as the case may be),  such  Optionee  may, but only within thirty (30) days (or
such  other  period of time,  not  exceeding  three (3) months in the case of an
Incentive  Stock  Option or six (6) months in the case of a  Nonstatutory  Stock
Option,  as is determined by the Board) after the date of such  termination (but
in no event later than the date of  expiration of the term of such Option as set
forth in the Option  Agreement),  exercise  his Option to the extent that he was
entitled to exercise it at the date of such  termination.  To the extent that he
was not entitled to exercise the Option at the date of such  termination,  or if
he does not exercise such Option (which he was entitled to exercise)  within the
time specified herein, the Option shall terminate.

          (c) Disability of Optionee.  Notwithstanding the provisions of Section
9(b) above, in the event of termination of an Optionee's Continuous Status as an
Employee or  Consultant as a result of his total and  permanent  disability  (as
defined in Section 22(e)(3) of the Code), he may, but only within six (6) months
(or such other period of time not exceeding  twelve (12) months as is determined
by the Board) from the date of such  termination (but in no event later than the
date of  expiration  of the  term of such  Option  as set  forth  in the  Option
Agreement),  exercise his Option to the extent he was entitled to exercise it at
the date of such termination. To the extent that he was not entitled to exercise
the Option at the date of  termination,  or if he does not exercise  such Option
(which he was entitled to exercise) within the time specified herein, the Option
shall terminate.

          (d) Death of Optionee. In the event of the death of an Optionee:

                           (i)during the term of the Option who is at the time 
of his death an Employee or Consultant of the Company and who shall have 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  twelve  (12) months
following  the date of death (but in no event later than the date of  expiration
of the  term of such  Option  as set  forth  in the  Option  Agreement),  by the
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
would have accrued had the Optionee  continued living and remained in Continuous
Status as an Employee or Consultant  twelve (12) months after the date of death,
subject to the limitation set forth in Section 5(b); or

                           (ii)within  thirty (30) days (or such other period of
time not exceeding three (3) months as is determined by the Board) after the
termination of Continuous Status as an Employee or Consultant, the Option may be
exercised,  at any time within  twelve (12) months  following  the date of death
(but in no event later than the date of expiration of the term of such Option as
set forth in the Option Agreement),  by the 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 date of termination.

          (e) Buyout Provisions.  The Administrator may at any time offer to buy
out for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

                                       26


 10. Non-Transferability of Options. Options may not be sold, pledged, assigned,
hypothecated,  transferred or disposed of in any manner other than by will or by
the laws of  descent  and  distribution  or  pursuant  to a  qualified  domestic
relations  order as  defined by the Code or Title I of the  Employee  Retirement
Income Security Act, or the rules  thereunder.  The designation of a beneficiary
by an  Optionee  does not  constitute  a transfer.  An Option may be  exercised,
during the  lifetime  of the  Optionee,  only by the  Optionee  or a  transferee
permitted by this Section 10.

 11.  Adjustments  Upon  Changes in  Capitalization  or  Merger.  Subject to any
required  action by the  shareholders  of the  Company,  the number of shares of
Common Stock  covered by each  outstanding  Option,  and the number of shares of
Common Stock which have been  authorized  for issuance  under the Plan but as to
which no Options have yet been  granted or which have been  returned to the Plan
upon  cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding  Option,  shall be proportionately
adjusted for any  increase or decrease in the number of issued  shares of Common
Stock  resulting  from a stock  split,  reverse  stock  split,  stock  dividend,
combination or  reclassification  of the Common Stock,  or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of  consideration  by the Company;  provided,  however,  that  conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of  consideration."  Such adjustment shall be made by the Board,
whose  determination  in that respect  shall be final,  binding and  conclusive.
Except as  expressly  provided  herein,  no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

     In the event of the proposed dissolution or liquidation of the Company, the
Board  shall  notify  the  Optionee  at least  fifteen  (15) days  prior to such
proposed action. To the extent it has not been previously exercised,  the Option
will terminate immediately prior to the consummation of such proposed action. In
the event of a merger  of the  Company  with or into  another  corporation,  the
Option shall be assumed or an  equivalent  option shall be  substituted  by such
successor  corporation or a parent or subsidiary of such successor  corporation.
In the even the successor corporation does not agree to assume the option or the
substitute and equivalent option, the Board shall, in lieu of such assumption or
substitution, provide for the Optionee to have the right to vest in and exercise
the Option as to all of the  Optioned  Stock,  including  Shares as to which the
Option  would not  otherwise  be vested or  exercisable.  If the Board  makes an
Option fully vested and exercisable in lieu of assumption or substitution in the
event of a merger,  the Board shall notify the Optionee that the Option shall be
fully vested and  exercisable for a period of fifteen (15) days from the date of
such notice,  and the Option will  terminate upon the expiration of such period.
If,  in such a  merger,  the  Option  is  assumed  or an  equivalent  option  is
substituted  by such  successor  corporation  or a parent or  subsidiary of such
successor corporation,  and if during a one-year period after the effective date
of such merger, the Optionee's Continuous Status as an Employee or Consultant is
terminated  for any reason other than the  Optionee's  voluntary  termination of
such  relationship,  then the Optionee  shall have the right within  thirty days
thereafter  to exercise  the Option as to all of the Optioned  Stock,  including
Shares as to which the Option would not be otherwise  exercisable,  effective as
of the date of such termination.

 12. Stock Withholding to Satisfy Withholding Tax Obligations. At the discretion
of the Administrator,  Optionees may satisfy withholding obligations as provided
in this  paragraph.  When an Optionee incurs tax liability in connection with an
Option,  which tax liability is subject to tax withholding  under applicable tax
laws, and the Optionee is obligated to pay the Company an amount  required to be
withheld under applicable tax laws, the Optionee may satisfy the withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
upon exercise of the Option,  if any, that number of Shares having a Fair Market
Value equal to the amount required to be withheld.  The Fair Market Value of the
Shares to be withheld  shall be determined on the date that the amount of tax to
be withheld is to be determined.

                                       27


 13. Time of Granting  Options.  The date of grant of an Option  shall,  for all
purposes,  be the date on which the Board makes the determination  granting such
Option.  Notice  of the  determination  shall  be  given  to  each  Employee  or
Consultant  to whom an Option is so granted  within a reasonable  time after the
date of such grant.

 14. Amendment and Termination of the Plan.

          (a) Amendment and Termination. The Board may at any time amend, alter,
suspend or  discontinue  the Plan, but no amendment,  alteration,  suspension or
discontinuation  shall be made which  would  impair  the rights of any  Optionee
under any grant theretofore made,  without his or her consent.  In addition,  to
the extent  necessary  and  desirable to comply with Section 422 of the Code (or
any other  applicable law or regulation,  including the requirements of the NASD
or an established stock exchange), the Company shall obtain shareholder approval
of any Plan amendment in such a manner and to such a degree as required.

          (b)  Effect  of  Amendment  or  Termination.  Any  such  amendment  or
termination  of the Plan  shall not  affect  Options  already  granted  and such
Options  shall  remain  in full  force  and  effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

 15. Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant to
the  exercise of an Option  unless the  exercise of such Option and the issuance
and  delivery of such Shares  pursuant  thereto  shall  comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act, the rules and regulations promulgated thereunder, and
the requirements of any stock exchange upon which the Shares may then be listed,
and shall be further  subject to the  approval of counsel  for the Company  with
respect to such compliance.

     As a condition  to the  exercise of an Option,  the Company may require the
person  exercising  such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present  intention  to sell or  distribute  such  Shares  if, in the  opinion of
counsel  for  the  Company,  such a  representation  is  required  by any of the
aforementioned relevant provisions of law.

 16. Reservation of Shares.  The Company,  during the term of this Plan, will at
all  times  reserve  and  keep  available  such  number  of  Shares  as shall be
sufficient to satisfy the requirements of the Plan.

          The inability of the Company to obtain  authority  from any regulatory
body having jurisdiction,  which authority is deemed by the Company's counsel to
be necessary  to the lawful  issuance  and sale of any Shares  hereunder,  shall
relieve the Company of any  liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained.

 17. Option  Agreement.  Options shall be evidenced by written option agreements
in such form as the Board shall approve.

 18. Shareholder Approval.  Continuance of the Plan shall be subject to approval
by the shareholders of the Company within twelve (12) months before or after the
date the Plan is adopted.  Such  shareholder  approval  shall be obtained in the
degree and manner required under Applicable Laws.
