                         (effective as of July 6, 1998)


     1. Purposes of the Plan. The purposes of this Directors'  Stock Option Plan
are to attract and retain the best available  personnel for service as Directors
of the Company, to provide additional  incentive to the Outside Directors of the
Company to serve as Directors,  and to encourage their continued  service on the
Board.

          Fair Market Value of a Share of Common Stock shall be the mean between
          the high  and low  asked  prices  for the  Common  Stock on the day of
          determination,  as reported  in The Wall Street  Journal or such other
          source as the Board deems reliable, or;

               (iii) In the  absence  of an  established  market  for the Common

the Plan, the maximum  aggregate number of Shares which may be optioned and sold
under the Plan is 600,000  Shares plus an annual  increase to be added each year
on July 1  beginning  on July 1,  1999 in an amount  equal to the  lesser of (i)
100,000 shares,  (ii) the number of shares subject to option grants in the prior
year  ending  June 30 or (iii) a lesser  number  determined  by the  Board  (the
"Pool")  of Common  Stock.  The  Shares  may be  authorized,  but  unissued,  or
reacquired Common Stock.

                                      -2-


     4. Administration of and Grants of Options under the Plan.

          (a) Administrator. Except as otherwise required herein, the Plan shall
     be  administered  by  the  Board,  or  by  a  compensation  committee  (the
     "Committee") appointed by the Board.

          (b) Procedure  for Grants.  All grants of Options  hereunder  shall be
     automatic  and  non-discretionary  and shall be made strictly in accordance
     with the following provisions:

               (i) No person shall have any  discretion  to select which Outside
          Directors  shall be  granted  Options  or to  determine  the number of
          Shares to be covered by Options granted to Outside Directors.

               (ii) Each  Outside  Director  shall be  automatically  granted an
          Option to purchase  40,000  Shares  (which  number shall be subject to
          adjustment  in the  manner  set forth in  Section  10 hereof  upon the
          occurrence of any event described therein) upon the date on which such
          person first becomes a Director (an "Initial Grant"),  whether through
          election by the  stockholders  of the Company or by appointment by the
          Board to fill a vacancy.

               (iii) On the date of each Annual  Meeting during the term of this
          Plan, each Outside  Director who has served as a Director for at least
          the previous six (6) months shall  automatically  receive an Option to
          purchase 10,000 Shares, which number shall be subject to adjustment in
          the manner set forth in Section 10 hereof upon the  occurrence  of any
          event described therein (a "Renewal Grant").

               (iv)  The  terms of each  Option  granted  hereunder  shall be as
          follows:

                    (A) the term of the Option shall be ten (10) years.

                    (B) the Option shall be  exercisable  only while the Outside
               Director  remains  a  Service  Provider,  except  as set forth in
               Section 8 hereof.

                    (C) the  exercise  price per Share shall be 100% of the Fair
               Market Value per Share on the date of grant of the Option.

                    (D) the Initial  Grant will vest and become  exercisable  as
               follows:

                    24% of the Shares  subject to the Option  shall vest  twelve
               months  after  the  Option's  grant  date,  and 2% of the  Shares
               subject to the Option shall vest each month  thereafter,  subject
               to the Outside  Director  continuing to be a Service  Provider on
               such dates.

                    (E) The Renewal  Grants will vest and become  exercisable as
               to 2% of the Shares  subject to such Option each month  beginning
               with the first month after the grant date, subject to the Outside
               Director continuing to be a Service Provider on such dates.



                                      -3-


               (v) In the event  that any  Option  granted  under the Plan would
          cause the number of Shares  subject to  outstanding  Options  plus the
          number of Shares  previously  purchased  upon  exercise  of Options to
          exceed  the Pool,  then each such  automatic  grant  shall be for that
          number of Shares  determined  by dividing  the total  number of Shares
          remaining  available  for grant by the number of Outside  Directors on
          the automatic  grant date. No further  grants shall be made until such
          time,  if any, as additional  Shares become  available for grant under
          the Plan through action of the  stockholders to increase the number of
          Shares which may be issued under the Plan or through  cancellation  or
          expiration of Options previously granted hereunder.

          (c) Powers of the Board. Subject to the provisions and restrictions of
     the Plan,  the Board or the  Committee  shall  have the  authority,  in its
     discretion:  (i) to determine,  upon review of relevant  information and in
     accordance  with  Section  2(j) of the Plan,  the Fair Market  Value of the
     Common  Stock;  (ii) to interpret the Plan;  (iii) to prescribe,  amend and
     rescind rules and  regulations  relating to the Plan; (iv) to authorize any
     person to execute  on behalf of the  Company  any  instrument  required  to
     effectuate the grant of an Option previously granted hereunder;  and (v) to
     make  all  other  determinations  deemed  necessary  or  advisable  for the
     administration of the Plan.

          (d) Effect of Board's  Decision.  All  decisions,  determinations  and
     interpretations of the Board or the Committee shall be final.

     5.  Eligibility.  Options  may be granted  only to Outside  Directors.  All
Options shall be automatically granted in accordance with the terms set forth in
Section 4(b) hereof.  An Outside Director who has been granted an Option may, if
he or she is otherwise  eligible,  be granted an additional Option or Options in
accordance with such provisions.

     The Plan  shall  not  confer on any  Optionee  any right  with  respect  to
continuation of service as a Director or nomination to serve as a Director,  nor
shall it  interfere in any way with any rights which the Director or the Company
may have to terminate his or her directorship at any time.

     6. Term of Plan. The Plan shall become  effective upon the earlier to occur
of its adoption by the Board or its approval by the  stockholders of the Company
as described in Section 16 of the Plan.  It shall  continue in effect for a term
of ten (10) years unless sooner terminated under Section 12 of the Plan.

     7. Exercise Price and Consideration.

          (a) Exercise  Price.  The per Share  exercise price for Optioned Stock
     shall be 100% of the Fair  Market  Value  per Share on the date of grant of
     the Option.

          (b) Form of Consideration. 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 Board and may consist  entirely  of: (i) cash,
     (ii) check,  (iii) promissory note, (iv) other shares which (x) in the case
     of Shares acquired upon exercise of an Option either have been owned by the
     Optionee for more than six (6) 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


                                      -4-


     aggregate  exercise  price of the Shares as to which said  Option  shall be
     exercised,  (v)  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,
     (vi)  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,  (vii)
     by delivering an  irrevocable  subscription  agreement for the Shares which
     irrevocably  obligates the Optionee to take and pay for the Shares not more
     than  twelve (12)  months  after the date of  delivery of the  subscription
     agreement,  (viii) any combination of the foregoing methods of payment,  or
     (ix) such other  consideration  and method of payment  for the  issuance of
     Shares to the extent permitted by applicable law.

     8. Exercise of Option.

          (a)  Procedure  for  Exercise;  Rights as a  Stockholder.  Any  Option
     granted  hereunder  shall be  exercisable at such times as are set forth in
     Section  4(b)  hereof;   provided,   however,  that  no  Options  shall  be
     exercisable  until  stockholder  approval  of the Plan in  accordance  with
     Section 16 hereof has been obtained.

     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 consist of any  consideration  and method of payment
allowable  under  Section 7(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 other rights as a stockholder shall
exist with respect to the Optioned  Stock,  notwithstanding  the exercise of the
Option. A share certificate for the number of Shares so acquired shall be issued
to the  Optionee  as  soon as  practicable  after  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 10 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) Rule 16b-3.  Options granted to Outside Directors must comply with
     the applicable  provisions of Rule 16b-3 promulgated under the Exchange Act
     or any successor  thereto and shall contain such  additional  conditions or
     restrictions  as may be  required  thereunder  to qualify  for the  maximum
     exemption  from  Section  16 of the  Exchange  Act  with  respect  to  Plan
     transactions.

          (c)  Termination  of  Status  as a  Service  Provider.  If an  Outside
     Director  ceases to be a Service  Provider,  he or she may, but only within
     three (3) months after the date he or she ceases 


                                      -5-


     to be a Service  Provider,  exercise an Option to the extent that he or she
     was   entitled   to   exercise   it  at  the  date  of  such   termination.
     Notwithstanding  the  foregoing,  in no event may the  Option be  exercised
     after its five (5) year term has  expired.  To the extent that the Optionee
     was not entitled to exercise an Option at the date of such termination,  or
     if the Optionee does not exercise such Option (which he or she was entitled
     to exercise) within the time specified herein, the Option shall terminate.

          (d) Disability of Optionee.  Notwithstanding the provisions of Section
     8(c)  above,  in the event an  Optionee  is unable to continue as a Service
     Provider as a result of the Optionee's  total and permanent  disability (as
     defined in Section  22(e)(3) of the Code),  he or she may,  but only within
     six (6)  months  from the date of  termination,  exercise  an Option to the
     extent  that he or she was  entitled  to  exercise  it at the  date of such
     termination.  Notwithstanding the foregoing,  in no event may the Option be
     exercised after its five (5) year term has expired.  To the extent that the
     Optionee   was  not  entitled  to  exercise  the  Option  at  the  date  of
     termination,  or if the Optionee does not exercise such Option (which he or
     she was entitled to exercise) within the time specified herein,  the Option
     shall terminate.

          (e) Death of Optionee.  In the event of the death of an Optionee,  the
     Option may be  exercised,  at any time within six (6) months  following the
     date of death,  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 death.
     Notwithstanding  the  foregoing,  in no event may the  Option be  exercised
     after its five (5) year term has expired.

     9.  Non-Transferability  of Options . The Option may not be sold,  pledged,
assigned, hypothecated,  transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised,  during the
lifetime of the Optionee, only by the Optionee.

     10. Adjustments Upon Changes in Capitalization, Liquidation or Merger.

          (a) Changes in  Capitalization.  Subject to any required action by the
     stockholders  of  the  Company,  the  number  of  Shares  covered  by  each
     outstanding Option, and the number of Shares 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  covered  by each such  outstanding
     Option or Right,  shall be  proportionately  adjusted  for any  increase or
     decrease in the number of issued  Shares of  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 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 subject to an Option.



                                      -6-


          (b)  Dissolution  or  Liquidation.   In  the  event  of  the  proposed
     dissolution  or liquidation of the Company,  all  outstanding  Options will
     terminate  immediately  prior to the  consummation of such proposed action,
     unless  otherwise  provided by the Board. The Board may, in the exercise of
     its sole  discretion  in such  instances,  declare  that any  Option  shall
     terminate as of a date fixed by the Board and give each  Optionee the right
     to exercise his or her Option as to all or any part of the Optioned  Stock,
     including Shares as to which the Option would not otherwise be exercisable.

          (c) Merger or Asset Sale. In the event of a merger of the Company with
     or into another  corporation or the sale of substantially all of the assets
     of the Company,  outstanding  Options may be assumed or equivalent  options
     may be substituted  by the successor  corporation or a Parent or Subsidiary
     thereof  (the  "Successor  Corporation").   If  an  Option  is  assumed  or
     substituted  for,  the Option or  equivalent  option  shall  continue to be
     exercisable  as provided in Section 4 hereof for so long as the Optionee is
     a  Service  Provider  of  the  Company  or of  the  Successor  Corporation.
     Following such assumption or  substitution,  if the Optionee's  status as a
     Service  Provider  of the  Company  or of  the  Successor  Corporation,  as
     applicable,  is terminated  other than upon a voluntary  resignation by the
     Optionee, the Option or option shall become fully exercisable, including as
     to Shares for which it would not otherwise be exercisable.  Thereafter, the
     Option or option shall remain  exercisable in accordance with Sections 8(c)
     through (e) above.

     If the  Successor  Corporation  does not  assume an  outstanding  Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable,  including  as to  Shares  for  which it  would  not  otherwise  be
exercisable.  In such event the Board shall notify the Optionee  that the Option
shall be fully  exercisable  for a period of fifteen  (15) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

     For the  purposes of this  Section  10(c),  an Option  shall be  considered
assumed if, following the merger or sale of assets, the Option confers the right
to purchase or receive,  for each Share of Optioned  Stock subject to the Option
immediately prior to the merger or sale of assets,  the  consideration  (whether
stock,  cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the  effective  date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares).
If such  consideration  received  in the  merger or sale of assets is not solely
common stock of the successor  corporation or its Parent, the Administrator may,
with the consent of the successor corporation,  provide for the consideration to
be received  upon the exercise of the Option,  for each Share of Optioned  Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

     11. 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


                                      -7-


     his or her consent.  In addition,  to the extent necessary and desirable to
     comply with any  applicable  law or  regulation,  the Company  shall obtain
     stockholder  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.

     12.  Time of  Granting  Options.  The date of grant of an  Option  or Right
shall, for all purposes,  be the date determined in accordance with Section 4(b)
hereof.  Notice of the determination  shall be given to each Outside Director to
whom an Option is so  granted  within a  reasonable  time after the date of such
grant.

     13. 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,
state securities laws, 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.

     14. 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.
