a committee designated by the Board. Once appointed, such Committee shall serve
in its designated capacity until otherwise directed by the Board. The Board may
increase the size of the Committee and appoint additional members, remove
members (with or without cause) and substitute new members, fill vacancies
(however caused), and remove all members of the Committee and thereafter
directly administer the Plan, all to the extent permitted by applicable laws.
 
          (b) Powers of the Administrator. Subject to the provisions of the
              ----------------------------
Plan, and in the case of a Committee, subject to 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(m) of the Plan;
 
              (ii)   to select the Consultants and Employees to whom Options may
be granted hereunder;
 
              (iii)  to determine whether and to what extent Options or any
combination thereof, are granted hereunder;
 
              (iv)   to determine the number of shares of Common Stock to be
covered by each Option granted hereunder;
 
                                      -3-
<PAGE>
 
              (v)    to approve the form(s) 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. Such terms and
conditions include, but are not limited to, the exercise price, the time or
times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;
 
              (vii)  to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan;
 
              (viii) to prescribe, amend and rescind rules and regulations
relating to the Plan;
 
              (ix)   to modify or amend each Option (subject to Section 14(b) of
the Plan);
 
              (x)    to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Option previously granted by
the Administrator;
 
              (xi)   to determine the terms and restrictions applicable to
Options; and
 
              (xii)  to make all other determinations deemed necessary or
advisable for administering the Plan.
 
          (c) Effect of Administrator's Decision. The Administrator's decisions,
              -----------------------------------
determinations and interpretations shall be final and binding on all Optionees
and any other holders of Options.
 
       5. Eligibility. Nonstatutory Stock Options may be granted under this Plan
          ------------
only to Employees and Consultants. If otherwise eligible, an Employee or
Consultant who has been granted an Option may be granted additional Options.
 
       6. No Right of Employment. Neither the Plan nor any Option shall confer
          -----------------------
upon an Optionee any right with respect to continuing the Optionee's employment
or consulting relationship with the Company, nor shall they interfere in any way
with the Optionee's right or the Company's right to terminate such employment at
any time, with or without cause.
 
       7. Term of Plan. The Plan shall become effective upon its adoption by the
          -------------
Board. It shall continue in effect for a term of ten (10) years unless
terminated earlier under Section 14 of the Plan.
 
       8. Term of Option. The term of each Option shall be stated in the Option
          ---------------
Agreement.
 
                                      -4-
<PAGE>
 
       9. Option Exercise Price and Consideration.
          ----------------------------------------
 
          (a) Exercise Price. The per share exercise price for the Shares to be
              ---------------
issued pursuant to exercise of an Option shall be determined by the
Administrator.
 
          (b) Waiting Period and Exercise Dates. At the time an Option is
              ----------------------------------
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised. In so doing, the Administrator may specify that an
Option may not be exercised until the completion of a service period.
 
          (c) Form of Consideration. The Administrator shall determine the
              ----------------------
acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may consist entirely of:
 
              (i)    cash;
 
              (ii)   check;
 
              (iii)  other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) 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)   delivery of a properly executed notice of exercise,
together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price;
 
              (v)    any combination of the foregoing methods of payment; or
 
              (vi)   such other consideration and method of payment for the
issuance of Shares to the extent permitted by applicable laws.
 
      10. Exercise of Option.
          -------------------
 
          (a) Procedure for Exercise; Rights as a Shareholder. Any Option
              ------------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as are determined by the Administrator and
set forth in the Option Agreement. An Option shall be deemed exercised when the
Company receives: (i) an executed written notice of exercise from the person
entitled to exercise the Option, (ii) full payment for the Shares with respect
to which the Option is being exercised, and (iii) full payment for any federal,
state and local tax withholding obligations and fees arising from the exercise
of the Option. Full payment may consist of any consi-
 
                                      -5-
<PAGE>
 
deration and method of payment authorized by the Administrator and permitted by
the Option Agreement and the Plan, except that federal, state and local tax
withholding obligations and fees must be paid by cash or check. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the stock certificate evidencing such Shares is issued (as evidenced by
the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company), 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. The Company shall issue (or cause to
be issued) such stock certificate promptly after the Option is exercised and
full payment is made. 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 12 of the Plan.
 
          (b) Effect of Exercise on Shares Available. Exercising an Option in
              ---------------------------------------
any manner shall decrease the number of Shares thereafter 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.
 
          (c) No Fractional Shares. An Option may not be exercised for a
              ---------------------
fraction of a Share.
 
          (d) Exercise Following Termination.
              -------------------------------
 
              (i) Termination of Employment or Consulting Relationship. In the
                  -----------------------------------------------------
event that an Optionee's Continuous Status as an Employee or Consultant
terminates (but not in the event of a change of status from Employee to
Consultant or from Consultant to Employee), other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within
three months from the date of termination (or within such lesser period as may
be specified in the Option Agreement), and only to the extent that the Optionee
was entitled to exercise it at the date of termination (but in no event later
than the expiration of the term of such Option as set forth in the Option
Agreement). If, at the date of termination, the Optionee is not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time
specified by the Administrator, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.
 
              (ii) Disability of Optionee. In the event that an Optionee's
                   -----------------------
Continuous Status as an Employee or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option at any time
within six (6) months from the date of such termination (or within such lesser
period as may be specified in the Option Agreement), but only to the extent that
the Optionee was entitled to exercise it at the date of such termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement). If, at the date of termination, the Optionee is not
entitled to exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall immediately revert to the Plan. If,
after termination, the Optionee does
 
                                      -6-
<PAGE>
 
not exercise his or her Option within the time specified herein, the Option
shall terminate, and the Shares covered by such Option shall revert to the Plan.
 
              (iii) Death of Optionee. In the event of the death of an Optionee,
                    ------------------
the Option may be exercised at any time within twelve (12) months (or within
such lesser period as may be specified in the Option Agreement) following the
date of death (but in no event later than the 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 that the Optionee was entitled to exercise the Option at
the date of death. If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If, after death, the
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.
 
      11. Non-Transferability of Options. An 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.
 
      12. Adjustments Upon Changes in Capitalization, Dissolution, Merger, Asset
          ----------------------------------------------------------------------
          Sale or Change of Control.
          --------------------------
 
          (a) Changes in Capitalization. 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.
 
          (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 will terminate immediately prior to the
consummation of such proposed action. The Board may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date
 
                                      -7-
<PAGE>
 
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. Subject to the provisions of paragraph (d)
              ---------------------
hereof, 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 (i)
each outstanding Option may be assumed or an equivalent option or right may be
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. If the Option is not assumed or substituted, the
Administrator shall provide that (a) the Optionee shall have the right to
exercise the Option as to all or a portion of the Optioned Stock, including
Shares as to which it would not otherwise be exercisable. If the Administrator
makes an Option fully exercisable in the event of a merger or sale of assets,
the Administrator shall notify the Optionee that the Option shall be fully
exercisable for a specified period from the date of such notice, and the Option
will terminate upon the expiration of such period. If the Option is to
terminate, the Administrator shall notify the Optionee, which notice shall be
given at least 15 days prior to the date the merger or sale of assets is
consummated. For the purposes of this paragraph, the Option shall be considered
assumed if, following the merger or sale of assets, the option or right confers
the right to purchase, 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);
provided, however, that if such consideration received in the merger or sale of
assets was 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.
 
          (d) Change in Control. In the event of a "Change in Control" of the
              ------------------
Company, as defined in paragraph (e) below, then the following acceleration and
valuation provisions shall apply:
 
              (i)    Except as otherwise determined by the Board, in its
discretion, prior to the occurrence of a Change in Control, any Options
outstanding on the date such Change in Control is determined to have occurred
that are not yet exercisable and vested on such date shall become fully
exercisable and vested;
 
              (ii)   Except as otherwise determined by the Board, in its
discretion, prior to the occurrence of a Change in Control, all outstanding
Options, to the extent they are exercisable and vested (including Options that
shall become exercisable and vested pursuant to subparagraph (i) above), shall
be terminated in exchange for a cash payment equal to the Change in Control
Price, (reduced by the exercise price applicable to such Options). These cash
proceeds shall be paid to the Optionee or, in the event of death of an Optionee
prior to
 
                                      -8-
<PAGE>
 
payment, to the estate of the Optionee or to a person who acquired the right to
exercise the Option by bequest or inheritance.
 
          (e) Definition of "Change in Control". For purposes of this Section
              ----------------------------------
12, a "Change in Control" means the happening of any of the following:
 
              (i)    When any "person," as such term is used in Sections 13(d)
and 14(d) of the Exchange Act (other than the Company, a Subsidiary or a Company
employee benefit plan, including any trustee of such plan acting as trustee) is
or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Company representing more
than twenty-five percent (25%) of the combined voting power of the Company's
then outstanding securities entitled to vote generally in the election of
directors; or
 
              (ii)   A merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least seventy-five percent
(75%) of the total voting power represented by the voting securities of the
Company or such surviving entity outstanding immediately after such merger or
consolidation, or the shareholders of the Company approve an agreement for the
sale or disposition by the Company of all or substantially all the Company's
assets; or
 
              (iii)  A change in the composition of the Board of Directors of
the Company occurring within a two-year period, as a result of which fewer than
a majority of the directors are Incumbent Directors. "Incumbent Directors" shall
mean directors who either (A) are directors of the Company as of the date the
Plan is approved by the shareholders, or (B) are elected, or nominated for
election, to the Board of Directors of the Company with the affirmative votes of
at least a majority of the Incumbent Directors at the time of such election or
nomination (but shall not include an individual whose election or nomination is
in connection with an actual or threatened proxy contest relating to the
election of directors to the Company).
 
          (f) Change in Control Price. For purposes of this Section 12, "Change
              ------------------------
in Control Price" shall be, as determined by the Board, (i) the highest Fair
Market Value of a Share within the 60 day period immediately preceding the date
of determination of the Change in Control Price by the Board (the "60-Day
Period"), or (ii) the highest price paid or offered per Share, as determined by
the Board, in any bona fide transaction or bona fide offer related to the Change
in Control of the Company, at any time within the 60-Day Period, or (iii) some
lower price as the Board, in its discretion, determines to be a reasonable
estimate of the fair market value of a Share.
 
      13. Date of Grant. The date of grant of an Option shall be, for all
          --------------
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is
 
                                      -9-
<PAGE>
 
determined by the Administrator. Notice of the determination shall be provided
to each Optionee 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 terminate the Plan.
 
           (b) Effect of Amendment or Termination. No amendment, alteration,
               -----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
 
      15. Conditions Upon Issuance of Shares.
          -----------------------------------
 
           (a) Legal Compliance. 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 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 or quotation system upon which the Shares may
then be listed or quoted, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.
 
           (b) Investment Representations. 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.
 
      16. Liability of Company.
          ---------------------
 
           (a) Inability to Obtain Authority. 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.
 
           (b) Grants Exceeding Allotted Shares. If the Optioned Stock covered
               ---------------------------------
by an Option exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan without additional shareholder approval, such Option shall
be void with respect to such excess Optioned Stock.
 
                                      -10-
<PAGE>
 
      17. 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.

Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder. All grants of Options to Outside Directors under this Plan 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 13,333 Shares (the "First Option") on the date on which the
later of the following events occurs: (A) the effective date of this Plan, as
determined in accordance with Section 6 hereof, or (B) the date on which such
person first becomes a Director, whether through election by the stockholders of
the Company or appointment by the Board to fill a vacancy.
 
              (iii)  After the First Option has been granted to an Outside
Director, such Outside Director shall thereafter be automatically granted an
Option to purchase 4,000 Shares (a "Subsequent Option") on January 1 of each
year, if on such date, he shall have served on the Board for at least six (6)
months.
 
              (iv)   Notwithstanding the provisions of subsections (ii) and
(iii) hereof, any grant of an Option made before the Company has obtained
stockholder approval of the Plan in accordance with Section 16 hereof shall be
conditioned upon obtaining such stockholder 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.
 
                     (B) the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, 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 First Option.
 
                     (D) the First Option shall become exercisable in
installments cumulatively as to twenty-five percent of the Shares subject to the
First Option on each anniversary of its date of grant.

                     (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
Section 8 hereof.
 
                                      -3-
<PAGE>
 
                     (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) the Subsequent Option shall become exercisable as to
twenty-five percent of the Shares subject to the Subsequent Option on each
anniversary of its date of grant.
 
              (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 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 shall have the authority, in its discretion: (i) to
determine, upon review of relevant information and in accordance with Section
2(i) 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 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 is otherwise eligible, be granted an additional Option or Options in
accordance with such provisions.
 
          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 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 11 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.
 
                                      -4-
<PAGE>
 
          (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, 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, (v) delivery of a properly executed
exercise notice together with such other documentation as the Board and the
broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, (vi) delivery of 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, (vii) any combination of the foregoing methods of payment, or (viii)
such other consideration and method of payment for the issuance of Shares to the
extent permitted under 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
 
                                      -5-
<PAGE>
 
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 Continuous Status as a Director. In the event an
              -----------------------------------------------
Optionee's Continuous Status as a Director terminates (other than upon the
Optionee's death or total and permanent disability (as defined in Section
22(e)(3) of the Code)), the Optionee may exercise his or her Option, but only
within three (3) months from the date of such termination, and only to the
extent that the Optionee was entitled to exercise it at 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 at
the date of such termination, 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.
 
          (d) Disability of Optionee. In the event Optionee's Continuous Status
              -----------------------
as a Director terminates as a result of total and permanent disability (as
defined in Section 22(e)(3) of the Code), the Optionee may exercise his or her
Option, but only within twelve (12) months from the date of such termination,
and only to the extent that the Optionee was entitled to exercise it at 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 at 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.
 
          (e) 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 at 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 at 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, Asset
          ----------------------------------------------------------------------
          Sale or Change of Control.
          -------------------------
 
          (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, shall be
proportionately adjusted for
 
                                      -6-
<PAGE>
 
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." 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.
 
           (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 will terminate immediately prior to the
consummation of such proposed action. 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, each outstanding Option shall be assumed or an equivalent option
shall be substituted by the successor corporation or a Parent or Subsidiary of
the successor corporation. In the event that the successor corporation does not
agree to assume the Option or to substitute an equivalent option, the Board
shall, in lieu of such assumption or substitution, provide for the Optionee to
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be exercisable. If the Board makes an
Option fully exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and the Option will terminate upon the expiration of such period.
For the purposes of this paragraph, the Option shall be considered assumed if,
following the merger or sale of assets, the option or right confers the right to
purchase, 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);
provided, however, that if such consideration received in the merger or sale of
assets was not solely Common Stock of the successor corporation or its Parent,
the Board may, with the consent of the successor corporation and the
participant, 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.
           --------------------------------------
 
                                      -7-
<PAGE>
 
          (a) Amendment and Termination. Except as set forth in Section 4, 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 Rule 16b-3 under the Exchange Act (or any other 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 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.
 
          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.
 
      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.
 
                                      -8-
<PAGE>
 
       16. Stockholder Approval. Continuance of the Plan shall be subject to
           ---------------------
approval by the stockholders of the Company at or prior to the first annual
meeting of stockholders held subsequent to the granting of an Option hereunder.
Such stockholder approval shall be obtained in the degree and manner required
under applicable state and federal law.

       RE: REGISTRATION STATEMENT ON FORM S-8
 
Ladies and Gentlemen:
 
       We have examined the Registration Statement on Form S-8 to be filed by
you with the Securities and Exchange Commission on or about November 25, 1996
(the "Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 1,000,000 shares of your Common Stock
reserved for issuance under the 1995 Nonstatutory Stock Option Plan, and 50,000
shares of your Common Stock reserved for issuance under the 1993 Director Stock
Option Plan. Such plans are referred to herein as the "Plans" and such shares of
Common Stock are referred to herein as the "Shares." As your counsel, we have
examined and are familiar with the proceedings taken by you in connection with
the issuance of the Shares under the Plans.
 
       It is our opinion that, when issued in the manner referred to in the
Plans, the Shares will be legally and validly issued, fully paid and
nonassessable.
 
       We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, and in any prospectus used in connection with the sale
of the Shares.
 
                                           Very truly yours,
