<PAGE>   5
                     (iii)   Rule 16b-3.  To the extent desirable to qualify
transactions hereunder as exempt under Rule 16b-3, the transactions

exemption under Rule 16b-3.
 
                     (iv)    Other Administration.  Other than as provided
above, the Plan shall be administered by (A) the Board or (B) a Committee,
which committee shall be constituted to satisfy 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;
 
                     (ii)    to select the Service Providers to whom Options
and Stock Purchase Rights may be granted hereunder;
 
                     (iii)   to determine the number of shares of Common Stock
to be covered by each Option and Stock Purchase Right granted hereunder;
 
                     (iv)    to approve forms of agreement for use under the
Plan;
 
                     (v)     to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any Option or Stock Purchase Right
granted hereunder.  Such terms and conditions include, but are not limited to,
the exercise price, the time or times when Options or Stock Purchase Rights 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 Stock Purchase Right or the shares of Common
Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;
 
                     (vi)    to reduce the exercise price of any Option or
Stock Purchase Right to the then current Fair Market Value if the Fair Market
Value of the Common Stock covered by such Option or Stock Purchase Right shall
have declined since the date the Option or Stock Purchase Right was granted;
 
                     (vii)   to institute an Option Exchange Program;
 
                     (viii)  to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;
 
 
 
 
 
                                      -5-
<PAGE>   6
                     (x)     to modify or amend each Option or Stock Purchase
Right (subject to Section 15(c) of the Plan), including the discretionary
authority to extend the post-termination exercisability period of Options
longer than is otherwise provided for in the Plan;
 
                     (xi)    to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right 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.  All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form
and under such conditions as the Administrator may deem necessary or advisable;
 
                     (xii)   to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;
 
                     (xiii)  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 or Stock Purchase Rights.
 
       5.     Eligibility.  Nonstatutory Stock Options and Stock Purchase
Rights may be granted to Service Providers.  Incentive Stock Options may be
granted only to Employees.
 
       6.     Limitations.
 
              (a)    Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options.  For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted.  The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.
 
              (b)    Neither the Plan nor any Option or Stock Purchase Right
shall confer upon an Optionee any right with respect to continuing the
Optionee's relationship as a Service Provider with the Company, nor shall they
interfere in any way with the Optionee's right or the Company's right to
terminate such relationship at any time, with or without cause.
 
              (c)    The following limitations shall apply to grants of
Options:
 
 
 
 
 
                                      -6-
<PAGE>   7
   
                     (i)     No Service Provider shall be granted, in any
fiscal year of the Company, Options to purchase more than 2,000,000 Shares.
    
 
   
                     (ii)    In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional
2,000,000 Shares which shall not count against the limit set forth in
subsection (i) above.
    
 
                     (iii)   The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization
as described in Section 13.
 
                     (iv)    If an Option is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 13), the cancelled Option will be counted
against the limits set forth in subsections (i) and (ii) above.  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.
 
       7.     Term of Plan.  Subject to Section 19 of the 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 15 of the
Plan.
 
       8.     Term of Option.  The term of each Option shall be stated in the
Option Agreement.  In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided
in the Option Agreement.  Moreover, in the case of an Incentive Stock Option
granted to an Optionee who, at the time the Incentive Stock Option is granted,
owns stock representing more than ten percent (10%) of the total combined
voting power of all classes of stock of the Company or any Parent or
Subsidiary, the term of the Incentive Stock Option shall be five (5) years from
the date of grant or such shorter term as may be provided in the Option
Agreement.
 
       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, subject to the following:
 
                     (i)     In the case of an Incentive Stock Option
 
                             (A)  granted to an Employee who, at the time the
Incentive Stock 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 per Share exercise price shall be no less than 110%
of the Fair Market Value per Share on the date of grant.
 
 
 
 
 
                                      -7-
<PAGE>   8
                             (B)  granted to any Employee other than an
Employee described in paragraph (A) immediately above, 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)    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.
 
              (c)    Form of Consideration.  The Administrator shall determine
the acceptable form of consideration for exercising an Option, including the
method of payment.  In the case of an Incentive Stock Option, the Administrator
shall determine the acceptable form of consideration at the time of grant.
Such consideration may consist entirely of:
 
                     (i)     cash;
 
                     (ii)    check;
 
                     (iii)   promissory note;
 
                     (iv)    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;
 
                     (v)     consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;
 
                     (vi)    a reduction in the amount of any Company liability
to the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;
 
                     (vii)   any combination of the foregoing methods of 
payment; or
 
 
 
 
 
                                      -8-
<PAGE>   9
                     (viii)  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 determined by the
Administrator and set forth in the Option Agreement.  Unless the Administrator
provides otherwise, vesting of Options granted hereunder shall be tolled during
any unpaid leave of absence.  An Option may not be exercised for a fraction of
a Share.
 
                     An Option shall be deemed exercised when the Company
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii)
full payment for the Shares with respect to which the Option is exercised.
Full payment may consist of any consideration and method of payment authorized
by the Administrator and permitted by the Option Agreement and the Plan.
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 Shares are 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
Shares promptly after the Option is exercised.  No adjustment will be made for
a dividend or other right for which the record date is prior to the date the
Shares are issued, except as provided in Section 13 of the Plan.
 
                     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.
 
              (b)    Termination of Relationship as a Service Provider.  If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period
of time as is specified in the Option Agreement to the extent that the Option
is vested on 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).  In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for three (3) months following the Optionee's termination.  If, on
the date of termination, the Optionee is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall 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.
 
              (c)    Disability of Optionee.  If an Optionee ceases to be a
Service Provider as a result of the Optionee's Disability, the Optionee may
exercise his or her Option within such period of time as
 
 
 
 
 
                                      -9-
<PAGE>   10
is specified in the Option Agreement to the extent the Option is vested on
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).  In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for
twelve (12) months following the Optionee's termination.  If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does 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.
 
              (d)    Death of Optionee.  If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is
specified in the Option Agreement (but in no event later than the expiration of
the term of such Option as set forth in the Notice of Grant), by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance, but only to the extent that the Option is vested on the date of
death.  In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination.  If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan.  The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the
person(s) entitled to exercise the Option under the Optionee's will or the laws
of descent or distribution.  If the Option is not so exercised within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.
 
              (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.
 
       11.    Stock Purchase Rights.
 
              (a)    Rights to Purchase.  Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan.  After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically, by means of a Notice of Grant,
of the terms, conditions and restrictions related to the offer, including the
number of Shares that the offeree shall be entitled to purchase, the price to
be paid, and the time within which the offeree must accept such offer.  The
offer shall be accepted by execution of a Restricted Stock Purchase Agreement
in the form determined by the Administrator.
 
              (b)    Repurchase Option.  Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
Disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by
 
 
 
 
 
                                      -10-
<PAGE>   11
cancellation of any indebtedness of the purchaser to the Company.  The
repurchase option shall lapse at a rate determined by the Administrator.
 
              (c)    Other Provisions.  The Restricted Stock Purchase Agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.
 
              (d)    Rights as a Shareholder.  Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered
upon the records of the duly authorized transfer agent of the Company.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the Stock Purchase Right is exercised, except as provided
in Section 13 of the Plan.
 
       12.    Non-Transferability of Options and Stock Purchase Rights.  Unless
determined otherwise by the Administrator, an Option or Stock Purchase Right
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.
If the Administrator makes an Option or Stock Purchase Right transferable, such
Option or Stock Purchase Right shall contain such additional terms and
conditions as the Administrator deems appropriate.
 
       13.    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 of Common Stock
covered by each outstanding Option and Stock Purchase Right, and the number of
shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options or Stock Purchase Rights have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option or Stock Purchase Right, as well as the price per share of Common Stock
covered by each such outstanding Option or Stock Purchase Right, 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 or Stock Purchase Right.
 
              (b)    Dissolution or Liquidation.  In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an
 
 
 
 
 
                                      -11-
<PAGE>   12
Optionee to have the right to exercise his or her Option until ten (10) days
prior to such transaction as to all of the Optioned Stock covered thereby,
including Shares as to which the Option would not otherwise be exercisable.  In
addition, the Administrator may provide that any Company repurchase option
applicable to any Shares purchased upon exercise of an Option or Stock Purchase
Right shall lapse as to all such Shares, provided the proposed dissolution or
liquidation takes place at the time and in the manner contemplated.  To the
extent it has not been previously exercised, an Option or Stock Purchase Right
will terminate immediately prior to the consummation of such proposed action.
 
              (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 and Stock Purchase Right
shall be assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation.  In the
event that the successor corporation refuses to assume or substitute for the
Option or Stock Purchase Right, the Optionee shall fully vest in and have the
right to exercise the Option or Stock Purchase Right as to all of the Optioned
Stock, including Shares as to which it would not otherwise be vested or
exercisable.  If an Option or Stock Purchase Right becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee in writing or
electronically that the Option or Stock Purchase Right shall be fully vested
and exercisable for a period of fifteen (15) days from the date of such notice,
and the Option or Stock Purchase Right shall terminate upon the expiration of
such period.  For the purposes of this paragraph, the Option or Stock Purchase
Right shall be considered assumed if, following the merger or sale of assets,
the option or right confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Option or Stock Purchase Right 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 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 or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, 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.
 
       14.    Date of Grant.  The date of grant of an Option or Stock Purchase
Right shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator.  Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.
 
       15.    Amendment and Termination of the Plan.
 
 
 
 
 
                                      -12-
<PAGE>   13
              (a)    Amendment and Termination.  The Board may at any time
amend, alter, suspend or terminate the Plan.
 
              (b)    Shareholder Approval.  The Company shall obtain
shareholder approval of any Plan amendment to the extent necessary and
desirable to comply with Applicable Laws.
 
              (c)    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.  Termination of the Plan shall not affect the Administrator's
ability to exercise the powers granted to it hereunder with respect to Options
granted under the Plan prior to the date of such termination.
 
       16.    Conditions Upon Issuance of Shares.
 
              (a)    Legal Compliance.  Shares shall not be issued pursuant to
the exercise of an Option or Stock Purchase Right unless the exercise of such
Option or Stock Purchase Right and the issuance and delivery of such Shares
shall comply with Applicable Laws 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 or Stock Purchase Right, the Company may require the
person exercising such Option or Stock Purchase Right 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.
 
       17.    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.
 
       18.    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.
 
       19.    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 manner and
to the degree required under Applicable Laws.

II.  AGREEMENT
 
       1.     Grant of Option.  The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share
set forth in the Notice of Grant (the "Exercise Price"), subject to the terms
and conditions of the Plan, which is incorporated herein by reference.  Subject
to Section 15(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.
 
              If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code.  However, if this Option is intended to be an
Incentive Stock Option, to the extent that it exceeds the $100,000 rule of Code
Section 422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").
 
       2.     Exercise of Option.
 
              (a)    Right to Exercise.  This Option is exercisable during its
term in accordance with the Vesting Schedule set out in the Notice of Grant and
the applicable provisions of the Plan and this Option Agreement.
 
              (b)    Method of Exercise.  This Option is exercisable by
delivery of an exercise notice, in the form attached as Exhibit A (the
"Exercise Notice"), which shall state the election to exercise the Option, the
number of Shares in respect of which the Option is being exercised (the
"Exercised Shares"), and such other representations and agreements as may be
required by the Company pursuant to the provisions of the Plan.  The Exercise
Notice shall be completed by the Optionee and delivered to [TITLE] of the
Company.  The Exercise Notice shall be accompanied by payment of the aggregate
Exercise Price as to all Exercised Shares.  This Option shall be deemed to be
exercised upon receipt by the Company of such fully executed Exercise Notice
accompanied by such aggregate Exercise Price.
 
              No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.
 
 
 
 
 
                                      -2-
<PAGE>   16
       3.     Method of Payment.  Payment of the aggregate Exercise Price shall
be by any of the following, or a combination thereof, at the election of the
Optionee:
 
              (a)    cash; or
 
              (b)    check; or
 
              (c)    consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan; or
 
              (d)    surrender of other Shares which (i) 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 (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.
 
       4.     Non-Transferability of Option.  This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by the
Optionee.  The terms of the Plan and this Option Agreement shall be binding
upon the executors, administrators, heirs, successors and assigns of the
Optionee.
 
       5.     Term of Option.  This Option may be exercised only within the
term set out in the Notice of Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option Agreement.
 
       6.     Tax Consequences.  Some of the federal tax consequences relating
to this Option, as of the date of this Option, are set forth below.  THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS
OPTION OR DISPOSING OF THE SHARES.
 
              (a)    Exercising the Option.
 
                     (i)     Nonstatutory Stock Option.  The Optionee may incur
regular federal income tax liability upon exercise of a NSO.  The Optionee will
be treated as having received compensation income (taxable at ordinary income
tax rates) equal to the excess, if any, of the Fair Market Value of the
Exercised Shares on the date of exercise over their aggregate Exercise Price.
If the Optionee is an Employee or a former Employee, the Company will be
required to withhold from his or her compensation or collect from Optionee and
pay to the applicable taxing authorities an amount in cash equal to a
percentage of this compensation income at the time of exercise, and may refuse
to honor the exercise and refuse to deliver Shares if such withholding amounts
are not delivered at the time of exercise.
 
 
 
 
 
                                      -3-
<PAGE>   17
                     (ii)    Incentive Stock Option.  If this Option qualifies
as an ISO, the Optionee will have no regular federal income tax liability upon
its exercise, although the excess, if any, of the Fair Market Value of the
Exercised Shares on the date of exercise over their aggregate Exercise Price
will be treated as an adjustment to alternative minimum taxable income for
federal tax purposes and may subject the Optionee to alternative minimum tax in
the year of exercise.  In the event that the Optionee ceases to be an Employee
but remains a Service Provider, any Incentive Stock Option of the Optionee that
remains unexercised shall cease to qualify as an Incentive Stock Option and
will be treated for tax purposes as a Nonstatutory Stock Option on the date
three (3) months and one (1) day following such change of status.
 
              (b)    Disposition of Shares.
 
                     (i)     NSO.  If the Optionee holds NSO Shares for at
least one year, any gain realized on disposition of the Shares will be treated
as long-term capital gain for federal income tax purposes.
 
                     (ii)    ISO.  If the Optionee holds ISO Shares for at
least one year after exercise and two years after the grant date, any gain
realized on disposition of the Shares will be treated as long-term capital gain
for federal income tax purposes.  If the Optionee disposes of ISO Shares within
one year after exercise or two years after the grant date, any gain realized on
such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the excess, if any, of the lesser of (A) the
difference between the Fair Market Value of the Shares acquired on the date of
exercise and the aggregate Exercise Price, or (B) the difference between the
sale price of such Shares and the aggregate Exercise Price.  Any additional
gain will be taxed as capital gain, short-term or long-term depending on the
period that the ISO Shares were held.
 
              (c)    Notice of Disqualifying Disposition of ISO Shares.  If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii)
one year after the exercise date, the Optionee shall immediately notify the
Company in writing of such disposition.  The Optionee agrees that he or she may
be subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.
 
   
       7.     Entire Agreement; Governing Law.  The Plan is incorporated herein
by reference.  The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and
supersede in their entirety all prior undertakings and agreements of the
Company and Optionee with respect to the subject matter hereof, and may not be
modified adversely to the Optionee's interest except by means of a writing
signed by the Company and Optionee.  This agreement is governed by the internal
substantive laws, but not the choice of law rules, of Delaware.
    
       8.     NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES AND
AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS
EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT
