          ---------------------------------------------------

          (a)  Procedure for Grants. All grants of Options to Outside Directors

under this Plan shall be automatic and nondiscretionary 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.

               (ii)  Each person who first becomes an Outside Director on or
after the IPO Effective Date, whether through election by the stockholders of
the Company or appointment by the Board to fill a vacancy shall be automatically
granted an Option to purchase up to 25,000 Shares (the "First Option") on the
date he or she first becomes an Outside Director; provided, however, that an
Inside Director who ceases to be an Inside Director but who remains a Director
shall not receive a First Option.

               (iii) Each Outside Director shall be automatically granted an
Option to purchase 5,000 Shares (a "Subsequent Option") on each annual meeting
of the stockholders of the Company occurring after the end of the Company's
fiscal year 2000, if immediately after such meeting, he or she shall continue to
serve on the Board and shall have served on the Board for at least the preceding
six (6) months.

               (iv)  Notwithstanding the provisions of subsections (ii) and
(iii) hereof, any exercise of an Option granted before the Company has obtained
shareholder approval of the Plan in accordance with Section 16 hereof shall be
conditioned upon obtaining such shareholder approval of the Plan in accordance
with Section 16 hereof.

               (v)   The terms of a First Option granted hereunder shall be as
follows:

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

                                                                             -3-

<PAGE>

                    (B) the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

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

                    (D) subject to Section 10 hereof, 20% of the Shares subject
to the First Option become exercisable on each anniversary from the date of
grant, provided that the Optionee continues to serve as a Director on such
dates.

              (vi)  The terms of a Subsequent Option granted hereunder shall be
as follows:

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

                    (B) the Subsequent Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

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

                    (D) subject to Section 10 hereof, 100% percent of the Shares
subject to the Subsequent Option become exercisable on the one year anniversary
of its date of grant, provided that the Optionee continues to serve as a
Director on such dates.

              (vii) 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 under Options to exceed the Pool, then the remaining
Shares available for Option grant shall be granted under Options to the Outside
Directors on a pro rata basis. 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 Board or the shareholders to increase the number of Shares which
may be issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

      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 hereof.

         The Plan shall not confer upon 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 the Director's relationship with the Company 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 shareholders of the Company
as described in Section 16

                                                                             -4-

<PAGE>

of the Plan. It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 11 of the Plan.


      7. 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
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an option have been owned by the Optionee for
more than six (6) months on the date of surrender, 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, (iv) consideration received
by the Company under a cashless exercise program implemented by the Company in
connection with the Plan, or (v) any combination of the foregoing methods of
payment.

      8. Exercise of Option.
         ------------------

         (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted
             -----------------------------------------------
hereunder shall be exercisable at such times as are set forth in Section 4
hereof; provided, however, that no Options shall be exercisable until
shareholder 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 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 shareholder 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
shall 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) Termination of Continuous Status as a Director. Subject to
             ----------------------------------------------
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or Disability), the Optionee may exercise
his or her Option, but only within three (3) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term). To the extent that the Optionee was not entitled to
exercise an Option on the date of such termination,

                                                                             -5-

<PAGE>

and to the extent that the Optionee does not exercise such Option (to the extent
otherwise so entitled) within the time specified herein, the Option shall
terminate.

          (c) Disability of Optionee. In the event Optionee's status as a
              ----------------------
Director terminates as a result of Disability, the Optionee may exercise his or
her Option, but only within twelve (12) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term). To the extent that the Optionee was not entitled to
exercise an Option on the date of termination, or if he or she does not exercise
such Option (to the extent otherwise so entitled) within the time specified
herein, the Option shall terminate.

          (d) Death of Optionee. In the event of an Optionee's death, the
              -----------------
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

     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, Dissolution, Merger or
          ------------------------------------------------------------------
Asset Sale.
-----------

          (a) Changes in Capitalization. Subject to any required action by the
              -------------------------
shareholders of the Company, the number of Shares covered by each outstanding
Option, 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, and the number of
Shares issuable pursuant to the automatic grant provisions of Section 4 hereof
shall be proportionately adjusted for any increase or decrease in the number of
issued Shares 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." 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.

          (b) Dissolution or Liquidation. In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

                                                                             -6-

<PAGE>

          (c) Change of Control. In the event of a Change of Control, each
              -----------------
outstanding Option held by an Outside Director shall vest and become exercisable
in full as to all of the Optioned Stock, including Shares as to which the
Outside Director would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable as provided in this paragraph, the
Administrator shall notify the Optionee in writing or electronically 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 shall terminate upon the expiration
of such period.

     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 his or her consent. In addition, to
the extent necessary and desirable to comply with any applicable law, regulation
or stock exchange rule, 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.

     12.  Time of Granting Options. The date of grant of an Option shall, for
          ------------------------
all purposes, be the date determined in accordance with Section 4 hereof.

     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.

          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.

                                                                             -7-

          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.

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

          16. Shareholder Approval. The Plan shall be subject to approval by the
              --------------------
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the degree and manner
required under applicable state and federal law and any stock exchange rules.

                                                                             -8-
