     price of (i) the weighted average exercise price of $11.96 per share
     covering outstanding options under the 1998 Stock Plan to purchase
     1,497,800 shares and (ii) $13.88 per share (the average of the high and the
     low prices of the Registrant's Class A Common Stock as reported on the 
     Nasdaq National Market on November 23, 1998) for 1,352,200 shares.

(3)  Computed in accordance with Rule 457(h) under the Securities Act of 1933,
     as amended. Such computation is based on $13.88 per share (85% of the
     average of the high and the low prices of the Registrant's Class A Common
     Stock as reported on the Nasdaq National Market System on November 23,
     1998). Pursuant to the 1998 Employee Stock Purchase Plan, shares are sold
     at 85% of the lesser of the fair market value of such shares on the first
     day of an offering period or last day of the applicable purchase period.

*       Incorporated by reference to the Registrant's Registration Statement on
        Form S-1, as amended (No. 333-53433), which was declared effective on
        July 27, 1998.

ITEM 9.   UNDERTAKINGS.

        (a)     The Registrant hereby undertakes:

                (i)     To file, during any period which offers or sales are
                        being made, a post-effective amendment to this
                        registration statement to include any material
                        information with respect to the plan of distribution not
                        previously disclosed in the registration statement or
                        any material change to such information in the
                        registration statement.

                (ii)    That, for the purpose of determining any liability under
                        the Securities Act, each post-effective amendment shall
                        be deemed to be a new registration statement relating to
                        the securities offered therein, and the offering of such
                        securities at that time shall be deemed to be the
                        initial bona fide offering thereof.

                (iii)   To remove from registration by means of a post-effective
                        amendment any of the securities being registered which
                        remain unsold at the termination of the offering.

        (b)     The Registrant hereby undertakes that, for purposes of
                determining any liability under the Securities Act, each filing
                of the Registrant's annual report pursuant to Section 13(a) or
                Section 15(d) of the Exchange Act (and, where applicable, each
                filing of an employee benefit plan's annual report pursuant to
                Section 15(d) of the Exchange Act) that is incorporated by
                reference in the Registration Statement shall be deemed to be a
                new registration statement relating to the securities offered
                therein, and the offering of such securities at that time shall
                be deemed to be the initial bona fide offering thereof.

        (c)     Insofar as indemnification for liabilities arising under the
                Securities Act may be permitted to directors, officers and
                controlling persons of the Registrant pursuant to law, the
                Registrant's Amended and Restated Certificate of Incorporation,
                Bylaws or indemnification agreements, or otherwise, the
                Registrant has been advised that in the opinion of the
                Securities and Exchange Commission such indemnification is
                against public policy as expressed in the Securities Act and is
                therefore unenforceable. In the event that a claim for
                indemnification against such liabilities (other than the payment
                by the Registrant of expenses incurred or paid by a director,
                officer or controlling person of the Registrant in a successful
                defense of any action, suit or proceeding) is asserted by such
                director, officer or controlling person in connection with the
                securities being registered hereunder, the Registrant will,
                unless in the opinion of its counsel the matter has been settled
                by controlling precedent, submit to a court of appropriate
                jurisdiction the question of whether such indemnification by it
                is against public policy as expressed in the Securities Act and
                will be governed by the final adjudication of such issue.

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

                  (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;

                  (ix) to prescribe, amend and rescind rules and regulations

established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

                  (x) to modify or amend each Option or Stock Purchase Right
(subject to Section 16(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;



                                      -5-


<PAGE>   6



                  (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)   On the date grants of Options under the Plan are required to
comply with Section 162(m) of the Code, the following limitations shall apply to
grants of Options:

                  (i) No Service Provider shall be granted, in any fiscal year
of the Company, Options to purchase more than 500,000 Shares.




                                      -6-


<PAGE>   7



                  (ii) In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 500,000 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 14.

                  (iv) If an Option is canceled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 14), the canceled 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 20 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 16 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. Prior to
the date the Common Stock is listed on a national securities exchange or a
national market system which qualifies under Section 25100(o) of the
Corporations Code of California, the term of each Option shall be no more than
ten (10) years from the date of grant.

      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.

                        (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.

<PAGE>   8



                  (ii) In the case of a Nonstatutory Stock Option granted:

                        (A) prior to the date the Common Stock is listed on a
national securities exchange or a national market system which qualifies under
Section 25100(o) of the Corporations Code of California:

                              (1) to a Service Provider who, at the time the
Nonstatutory 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
Affiliate, 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.

                              (2) granted to any other Service Provider, the per
Share exercise price shall be no less than 85% of the Fair Market Value per
Share on the date of grant.

                        (B) to any Service Provider, on or after the date the
Common Stock is listed on a national securities exchange or a national market
system which qualifies under Section 25100(o) of the Corporations Code of
California, 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; provided, however, that prior to the date the Common
Stock is listed on a national securities exchange or a national market system
which qualifies under Section 25100(o) of the Corporations Code of California,
except in the case of Options granted to Officers, Directors, and Consultants,
Options shall vest and become exercisable at a rate of no less than 20% per year
over five (5) years from the date the Options are granted.

            (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;



                                      -8-


<PAGE>   9



                  (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

                  (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 to Officers and Directors 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 14 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. Prior to the date the
Common Stock is listed on a national securities exchange or a national market
system which qualifies under Section 25100(o) of the Corporations Code of
California, such Option must remain exercisable for a period of at least thirty
(30) days after the Optionee ceases to be a Service Provider. 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 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. Prior to the date the Common Stock is listed on a national
securities exchange or a national market system which qualifies under Section
25100(o) of the Corporations Code of California, such Option must remain
exercisable for a period of at least six (6) months after the Optionee ceases to
be a Service Provider due to Optionee=s disability. 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. Prior to the date the Common Stock is listed on a national
securities exchange or a national market system which qualifies under Section
25100(o) of the Corporations Code of California, such Option must remain
exercisable for a period of at least six (6) months after the Optionee ceases to
be a Service Provider. 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 



                                      -10-

<PAGE>   11


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. Prior to the date the Common Stock is listed on
a national securities exchange or a national market system which qualifies under
Section 25100(o) of the Corporations Code of California, the terms of the offer
of Stock Purchase Rights under the Plan shall comply in all respects with
Section 260.140.42 of Title 10 of the California Code of Regulations.

            (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 cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator; provided, however, that prior to the date the Common Stock is
listed on a national securities exchange or a national market system which
qualifies under Section 25100(o) of the Corporations Code of California, except
with respect to Shares purchased by Officers, Directors, and Consultants, the
repurchase option shall in no case lapse at a rate of less than 20% per year
over five (5) years from the date of purchase.

            (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 14
of the Plan.

      12.   Non-Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator (provided, however, that such
determination shall occur only on or after the date the Common Stock is listed
on a national securities exchange or a national market system which qualifies
under Section 25100(o) of the Corporations Code of California), 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.   Automatic Option Grants to Outside Directors.

            (a)   First Option. Each Outside Director shall be automatically
granted an Option to purchase 10,000 Shares (the "First Option") on the date on
which the later of the following events occurs: (A) the consummation of the
Company's initial public offering of Common Stock, or (B) the date on which such
person first becomes an Outside Director, whether through election by the
stockholders of the Company or appointment by the Board to fill a vacancy;
provided, however, that an Inside Director who ceases to be an Inside Director
but who remains a Director shall not receive a First Option.

            (b)   Subsequent Option. Each Outside Director shall be
automatically granted an Option to purchase 5,000 Shares (a "Subsequent Option")
on March 1st of each year provided he or she is then an Outside Director and if
as of such date, he or she shall have served on the Board for at least the
preceding six (6) months.

            (c)   Terms of Options. The term of First Options and Subsequent
Options granted hereunder shall be as follows:

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

                  (B) the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant. In the event that the date of grant
is not a trading day, the exercise price per Share shall be the Fair Market
Value on the next trading day immediately following the date of grant.

                  (C) one-third of the Shares subject to the Option shall vest
on the date of grant, and 1/3 of the Shares subject to the Option shall vest on
the anniversary of the date of grant in each year thereafter so that 100% of the
Shares subject to the Option shall be vested two (2) years from the grant date,
subject to the Optionee remaining a Service Provider as of such vesting dates.

            (d)   Special Provisions Relating to Parent Officers and Directors.
The provisions of this Section 13(d) shall apply to Outside Directors who are
officers or directors of a Parent ("Outside Parent Directors"). First Options
and Subsequent Options that would otherwise be issuable to Outside Parent
Directors pursuant to Section 13(a) or (b) ("Parent Options") shall be 



                                      -12-

<PAGE>   13


issued to the Parent or its designee on the following terms and subject to the
following conditions and limitations:

                  (A) Each Parent Option shall be issued in accordance with the
written notice of the Parent to the Company (the "Parent Option Notice"),
delivered prior to the date of issuance of such Parent Option, pursuant to
action taken by the Parent's board of directors or an appropriate committee
thereof.

                  (B) Each Parent Option Notice may designate, in lieu of the
Outside Parent Director with respect to whose services the Parent Option is
being issued, one or more recipients of such Parent Option, or portions thereof,
provided that each such designee must be the Parent or a Service Provider.

                  (C) No Outside Parent Director shall be entitled to receive
any Parent Option or portion thereof unless he or she has been designated in a
Parent Option Notice to receive same. (D) In the absence of a Parent Option
Notice with respect to a Parent Option, such Option shall be issued to the
Parent.

                  (E) No First Option shall be issued with respect to an Outside
Parent Director who replaces an Outside Parent Director with respect to whom a
First Option was issued.

                  (F) Notwithstanding the provisions of Section 13(c)(C),
vesting of a Parent Option held by the Parent shall be subject to the Outside
Parent Director with respect to whom the Option was issued, or a replacement
Outside Parent Director, remaining a Director as of the vesting dates of such
Option.

                  (G) Notwithstanding the provisions of Section 12, each Parent
Option issued to the Parent shall be transferrable, but only to a Service
Provider. Further transfers of such Option shall be subject to Section 12.

            14.   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 



                                      -13-

<PAGE>   14


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 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, unless otherwise provided for in any employment,
compensation or other agreement with any Optionee, the Administrator shall
determine in its sole discretion, whether or not each 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 the Administrator determines that the Options or Stock
Purchase Rights become 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




                                      -14-

<PAGE>   15


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.

      15.   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.

      16.   Amendment and Termination of the Plan.

            (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.

      17.   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.

      18.   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.



                                      -15-


<PAGE>   16



      19.   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.

      20.   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.

      21.   Information to Optionees and Purchasers. Prior to the date the
Common Stock is listed on a national securities exchange or a national market
system which qualifies under Section 25100(o) of the Corporations Code of
California, the Company shall provide to each Optionee and to each individual
who acquires Shares pursuant to the Plan, not less frequently than annually
during the period such Optionee or purchaser has one or more Options or Stock
Purchase Rights outstanding, and, in the case of an individual who acquires
Shares pursuant to the Plan, during the period such individual owns such Shares,
copies of annual financial statements. The Company shall not be required to
provide such statements to key employees whose duties in connection with the
Company assure their access to equivalent information.

<PAGE>   18




Termination Period:

       This Option may be exercised for 30 days after Optionee ceases to be a
Service Provider; provided, however, that upon the first sale of Common Stock
pursuant to the Company's registration statement on Form S-1 (or any successor
form thereto) relating to its initial public offering being declared effective

after Optionee ceases to be a Service Provider. In no event shall this Option be
exercised later than the Term/Expiration Date as provided above.

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 16(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 the Executive Vice President,
Operations/Administration 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.



                                      -2-


<PAGE>   19



            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.

      3.    Optionee's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
at the time this Option is exercised, the Optionee shall, if required by the
Company, concurrently with the exercise of all or any portion of this Option,
deliver to the Company his or her Investment Representation Statement in the
form attached hereto as Exhibit B and shall read the applicable rules of the
Commissioner of Corporations attached to such Investment Representation
Statement.

      4.    Lock-Up Period. Optionee hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

      5.    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)   with the Administrator's consent, delivery of Optionee's
promissory note (the "Note") in the form attached hereto as Exhibit D, in the
amount of the aggregate Exercise Price of the Exercised Shares together with the
execution and delivery by the Optionee of the Security Agreement attached hereto
as Exhibit C. The Note shall bear interest at the "applicable federal rate"
prescribed under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the Security
Agreement.

<PAGE>   20



      6.    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.

      7.    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.

      8.    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.

                  (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.




                                      -4-


<PAGE>   21



                  (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.

      9.    Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement, including the Exhibits attached
hereto 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

Foster City, CA 94404


Attention:  Executive Vice President, Operations/Administration

      1.    Exercise of Option. Effective as of today, ________________, 199__,
the undersigned ("Purchaser") hereby elects to purchase ______________ shares

      4.    Rights as Shareholder. 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 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. The 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

<PAGE>   25



to repurchase the Shares (the "Repurchase Option") at any time between the 75th

exercise of the Option.

                  (ii) Shares shall be repurchased at their then Fair Market
Value determined in accordance with Section 2(n) of the Plan (the "Repurchase
Price".)

                  (iii) The Company shall exercise the Repurchase Option by
delivering written notice to the Purchaser or the Purchaser's executor AND, at
the Company's discretion, (a) by delivering to the Purchaser or the Purchaser's
executor a check in the amount of the aggregate Repurchase Price, or (b) by the
Company canceling an amount of the Purchaser's indebtedness to the Company equal
to the aggregate Repurchase Price, or (c) by a combination of (a) and (b) so
that the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Shares being repurchased and all rights
and interests therein or relating thereto, and the Company shall have the right
to retain and transfer to its own name the number of Shares being repurchased by
the Company.

                  (iv) If the Company does not elect to exercise the Repurchase
Option conferred above by giving the requisite notice, the Repurchase Option
shall terminate.

                  (v) Whenever the Company shall have the right to repurchase
Shares hereunder, the Company may designate and assign one or more employees,
officers, directors or stockholders of the Company or other persons or
organizations to exercise all or a part of the Company's purchase rights under
this Exercise Notice and purchase all or a part of such Shares.

            (b)   Release of Shares From Repurchase Option. The Shares subject
to the Company's Repurchase Option, or subject in the future to the Company's
Repurchase Option, pursuant to Section 5(a) above shall be released from such
option upon the first sale of Common Stock pursuant to the Company's
registration statement on Form S-1 (or any successor form thereto) relating to
its initial public offering being declared effective by the Securities and
Exchange Commission.

            (c)   Restriction on Transfer. The Purchaser agrees that Purchaser
shall not sell or transfer any Shares until the earlier to occur of: (a) six
months after the Purchaser acquires the Shares pursuant to this Exercise Notice,
or (b) 90 days after the Purchaser ceases to be a Service Provider, other than
by will or the laws of descent and distribution; any transferee pursuant to a
will or the laws of descent and distribution shall be bound by this Exercise
Notice.

            (d)   Escrow of Shares.

                  (i) To ensure the availability for delivery of the Purchaser's
Shares upon repurchase by the Company pursuant to the Company's Repurchase
Option, the Purchaser shall, upon execution of this Exercise Notice, deliver and
deposit with an escrow holder designated by the Company (the "Escrow Holder")
the share certificates representing the Shares, together with a stock 



                                      -2-


<PAGE>   26


assignment duly endorsed in blank (in such form as the Board approves, including
the form attached hereto as Exhibit A-2). The Shares and stock assignment shall
be held by the Escrow Holder pursuant to the Joint Escrow Instructions of the
Company and Purchaser (in such form as the Board approves, including the form
attached hereto as Exhibit A-2) until such time as the Company's Repurchase
Option terminates, is released or is exercised. As a further condition to the
Company's obligations, the spouse of the Purchaser, if any, shall execute and
deliver to the Company the Consent of Spouse attached hereto as Exhibit A-4.

                  (ii) The Escrow Holder shall not be liable for any act it may
do or omit to do with respect to holding the Shares in escrow and while acting
in good faith and in the exercise of its judgment.

                  (iii) If the Company or any assignee exercises its Repurchase
Option hereunder, the Escrow Holder, upon receipt of written notice of such
option exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

                  (iv) When the Repurchase Option is exercised, has terminated
or is released with respect to any Shares, upon Purchaser's request, the Escrow
Holder shall promptly cause such Shares to be issued and shall deliver such
Shares to the Company or the Purchaser, as the case may be.

                  (v) Subject to the terms hereof, the Purchaser shall have all
the rights of a stockholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Exercise Notice and the Company's Repurchase
Option.

      6.    Company's Right of First Refusal. Before any Shares held by
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

            (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the "Offered Price"), and the Holder shall offer the Shares
at the Offered Price to the Company or its assignee(s).



                                      -3-


<PAGE>   27



            (b)   Exercise of Right of First Refusal. At any time within thirty
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, or less than all,
of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

            (c)   Purchase Price. The purchase price (the "Purchase Price") for
the Shares purchased by the Company or its assignee(s) under this Section shall
be (i) the Offered Price in the case of Shares that are not subject to the
Company's Repurchase Option or (ii) in the case of Shares that are subject to
the Company's Repurchase Option, the lower of the Offered Price or the
Repurchase Price as defined in Section 5 hereof. If the Offered Price includes
consideration other than cash, the cash equivalent value of the non-cash
consideration shall be determined by the Board of the Company in good faith.

            (d)   Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within thirty (30) days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

            (e)   Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within one hundred twenty (120) days after the date of the Notice
and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section shall continue to apply to
the Shares in the hands of such Proposed Transferee. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, a
new Notice shall be given to the Company, and the Company and/or its assignees
shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred.

            (f)   Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, but subject to the
provisions of Section 5, the transfer of any or all of the Shares during the
Purchaser's lifetime or on the Purchaser's death by will or intestacy to the
Purchaser's immediate family or a trust for the benefit of the Purchaser's
immediate family shall be exempt from the provisions of this Section provided
that the Purchaser notifies the Company in writing within thirty (30) days of
said transfer. "Immediate Family" as used herein shall mean spouse, lineal
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Exercise Notice including, but not limited to
this Section and Section 5, and there shall be no further transfer of such
Shares except in accordance with the terms of this Exercise Notice.



                                      -4-


<PAGE>   28



            (g)   Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the first sale of Common Stock
pursuant to the Company's registration statement on Form S-1 (or any successor
form thereto) relating to its initial public offering being declared effective
by the Securities and Exchange Commission.

      7.    Restrictive Legends and Stop-transfer Orders.

            (a)   Legends. Purchaser understands and agrees that the Company
shall cause the legends set forth below or legends substantially equivalent
thereto, to be placed upon any certificate(s) evidencing ownership of the Shares
together with any other legends that may be required by the Company or by state
or federal securities laws:

                  THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE
                  OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
                  HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN
                  THE OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO
                  THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER,
                  PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

                  THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  CERTAIN RESTRICTIONS ON TRANSFER AND RIGHT OF FIRST REFUSAL
                  OPTIONS HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN
                  THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER
                  OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE
                  PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND
                  RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE
                  SHARES.

            (b)   Stop-transfer Notices. Purchaser agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

            (c)   Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Exercise Notice or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so
transferred.

      8.    Tax Consultation. Purchaser understands that Purchaser may suffer
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares. Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

      9.    Entire Agreement; Governing Law. The Plan and Option Agreement are
incorporated herein by reference. This Exercise Notice, the Plan and the 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 Purchaser with respect to the subject matter
hereof, and may not be modified adversely to the Purchaser's interest except by
means of a writing signed by the Company and Purchaser. This Exercise Notice is
governed by the internal substantive laws, but not the choice of law rules, of
California.

                                    EXHIBIT B

                       INVESTMENT REPRESENTATION STATEMENT

OPTIONEE:

COMPANY:             IDG BOOKS WORLDWIDE, INC.

SECURITY:            COMMON STOCK

AMOUNT:

DATE:


In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

            (a)   Optionee is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Securities. Optionee
is acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

            (b)   Optionee acknowledges and understands that the Securities
constitute "restricted securities" under the Securities Act and have not been
registered under the Securities Act in reliance upon a specific exemption
therefrom, which exemption depends upon, among other things, the bona fide
nature of Optionee's investment intent as expressed herein. In this connection,
Optionee understands that, in the view of the Securities and Exchange
Commission, the statutory basis for such exemption may be unavailable if
Optionee's representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax
statutes, for a deferred sale, for or until an increase or decrease in the
market price of the Securities, or for a period of one year or any other fixed
period in the future. Optionee further understands that the Securities must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. Optionee further
acknowledges and understands that the Company is under no obligation to register
the Securities. Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company, a legend prohibiting their
transfer without the consent of the Commissioner of Corporations of the State of
California and any other legend required under applicable state securities laws.

            (c)   Optionee is familiar with the provisions of Rule 701 and Rule
144, each promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly from the issuer thereof, in a non-public offering subject to 



<PAGE>   31



the satisfaction of certain conditions. Rule 701 provides that if the issuer
qualifies under Rule 701 at the time of the grant of the Option to the Optionee,
the exercise will be exempt from registration under the Securities Act. In the
event the Company becomes subject to the reporting requirements of Section 13 or
15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or
such longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of certain of
the conditions specified by Rule 144, including: (1) the resale being made
through a broker in an unsolicited "broker's transaction" or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of
certain public information about the Company, (3) the amount of Securities being
sold during any three month period not exceeding the limitations specified in
Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Option, then the Securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which requires the
resale to occur not less than one year after the later of the date the
Securities were sold by the Company or the date the Securities were sold by an
affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two years, the satisfaction of the
conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

            (d)   Optionee further understands that in the event all of the
applicable requirements of Rule 701 or 144 are not satisfied, registration under
the Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

                                       Signature of Optionee:

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

      (b)   It is unlawful for the holder of any such security to consummate a
sale or transfer of such security, or any interest therein, without the prior

Section 260.141.12 of these rules), except:

            (1)   to the issuer;

            (3)   to any person described in Subdivision (i) of Section 25102 of
      the Code or Section 260.105.14 of these rules;

            (4)   to the transferor's ancestors, descendants or spouse, or any

                                    EXHIBIT C

                               SECURITY AGREEMENT


        This Security Agreement is made as of __________, 19___ between IDG
Books Worldwide, Inc., a Delaware corporation ("Pledgee"), and
_________________________ ("Pledgor").


                                    Recitals

        Pursuant to Pledgor's election to purchase Shares under the Option
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under
Pledgee's 1998 Stock Plan, and Pledgor's election under the terms of the Option
to pay for such shares with his promissory note (the "Note"), Pledgor has
purchased _________ shares of Pledgee's Common Stock (the "Shares") at a price
of $________ per share, for a total purchase price of $__________. The Note and
the obligations thereunder are as set forth in Exhibit C to the Option.

      NOW, THEREFORE, it is agreed as follows:

      1.    Creation and Description of Security Interest. In consideration of
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor,
pursuant to the California Commercial Code, hereby pledges all of such Shares
(herein sometimes referred to as the "Collateral") represented by certificate
number ______, duly endorsed in blank or with executed stock powers, and
herewith delivers said certificate to the Secretary of Pledgee ("Pledgeholder"),
who shall hold said certificate subject to the terms and conditions of this
Security Agreement.

      The pledged stock (together with an executed blank stock assignment for
use in transferring all or a portion of the Shares to Pledgee if, as and when
required pursuant to this Security Agreement) shall be held by the Pledgeholder
as security for the repayment of the Note, and any extensions or renewals
thereof, to be executed by Pledgor pursuant to the terms of the Option, and the
Pledgeholder shall not encumber or dispose of such Shares except in accordance
with the provisions of this Security Agreement.

      2.    Pledgor's Representations and Covenants. To induce Pledgee to enter
into this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

            (a)   Payment of Indebtedness. Pledgor will pay the principal sum of
the Note secured hereby, together with interest thereon, at the time and in the
manner provided in the Note.

            (b)   Encumbrances. The Shares are free of all other encumbrances,
defenses and liens, and Pledgor will not further encumber the Shares without the
prior written consent of Pledgee.

            (c)   Margin Regulations. In the event that Pledgee's Common Stock
is now or later becomes margin-listed by the Federal Reserve Board and Pledgee
is classified as a "lender" within 



<PAGE>   35



the meaning of the regulations under Part 207 of Title 12 of the Code of Federal
Regulations ("Regulation G"), Pledgor agrees to cooperate with Pledgee in making
any amendments to the Note or providing any additional collateral as may be
necessary to comply with such regulations.

      3.    Voting Rights. During the term of this pledge and so long as all
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

      4.    Stock Adjustments. In the event that during the term of the pledge
any stock dividend, reclassification, readjustment or other changes are declared
or made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such securities, Pledgor, Pledgee and Pledgeholder shall
cooperate and execute such documents as are reasonable so as to provide for the
substitution of such Collateral and, upon such substitution, references to
"Shares" in this Security Agreement shall include the substituted shares of
capital stock of Pledgor as a result thereof.

        5. Options and Rights. In the event that, during the term of this
pledge, subscription Options or other rights or options shall be issued in
connection with the pledged Shares, such rights, Options and options shall be
the property of Pledgor and, if exercised by Pledgor, all new stock or other
securities so acquired by Pledgor as it relates to the pledged Shares then held
by Pledgeholder shall be immediately delivered to Pledgeholder, to be held under
the terms of this Security Agreement in the same manner as the Shares pledged.

      6.    Default. Pledgor shall be deemed to be in default of the Note and of
this Security Agreement in the event:

            (a)   Payment of principal or interest on the Note shall be
delinquent for a period of 10 days or more; or

            (b)   Pledgor fails to perform any of the covenants set forth in the
Option or contained in this Security Agreement for a period of 10 days after
written notice thereof from Pledgee.

      In the case of an event of Default, as set forth above, Pledgee shall have
the right to accelerate payment of the Note upon notice to Pledgor, and Pledgee
shall thereafter be entitled to pursue its remedies under the California
Commercial Code.

      7.    Release of Collateral. Subject to any applicable contrary rules
under Regulation G, there shall be released from this pledge a portion of the
pledged Shares held by Pledgeholder hereunder upon payments of the principal of
the Note. The number of the pledged Shares which shall be released shall be that
number of full Shares which bears the same proportion to the initial

<PAGE>   36


number of Shares pledged hereunder as the payment of principal bears to the
initial full principal amount of the Note.

      8.    Withdrawal or Substitution of Collateral. Pledgor shall not sell,
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

      9.    Term. The within pledge of Shares shall continue until the payment
of all indebtedness secured hereby, at which time the remaining pledged stock
shall be promptly delivered to Pledgor, subject to the provisions for prior
release of a portion of the Collateral as provided in paragraph 7 above.

      10.   Insolvency. Pledgor agrees that if a bankruptcy or insolvency
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

      11.   Pledgeholder Liability. In the absence of willful or gross
negligence, Pledgeholder shall not be liable to any party for any of his acts,
or omissions to act, as Pledgeholder.

      12.   Invalidity of Particular Provisions. Pledgor and Pledgee agree that
the enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

      13.   Successors or Assigns. Pledgor and Pledgee agree that all of the
terms of this Security Agreement shall be binding on their respective successors
and assigns, and that the term "Pledgor" and the term "Pledgee" as used herein
shall be deemed to include, for all purposes, the respective designees,
successors, assigns, heirs, executors and administrators.

      14.   Governing Law. This Security Agreement shall be interpreted and
governed under the internal substantive laws, but not the choice of law rules,

                            IDG BOOKS WORLDWIDE, INC.
                                 1998 STOCK PLAN

                       RESTRICTED STOCK PURCHASE AGREEMENT

      Unless otherwise defined herein, the terms defined in the Plan shall have
the same defined meanings in this Restricted Stock Purchase Agreement.

      WHEREAS the Purchaser named in the Notice of Grant, (the "Purchaser") is
an Service Provider, and the Purchaser's continued participation is considered
by the Company to be important for the Company's continued growth; and

      WHEREAS in order to give the Purchaser an opportunity to acquire an equity
interest in the Company as an incentive for the Purchaser to participate in the
affairs of the Company, the Administrator has granted to the Purchaser a Stock
Purchase Right subject to the terms and conditions of the Plan and the Notice of
Grant, which are incorporated herein by reference, and pursuant to this
Restricted Stock Purchase Agreement (the "Agreement").

      NOW THEREFORE, the parties agree as follows:

      1.    Sale of Stock. The Company hereby agrees to sell to the Purchaser
and the Purchaser hereby agrees to purchase shares of the Company's Common Stock
(the "Shares"), at the per Share purchase price and as otherwise described in
the Notice of Grant.

      2.    Payment of Purchase Price. The purchase price for the Shares may be
paid by delivery to the Company at the time of execution of this Agreement of
cash, a check, or some combination thereof.

      3.    Repurchase Option.

            (a)   In the event the Purchaser ceases to be a Service Provider for
any or no reason (including death or disability) before all of the Shares are
released from the Company's Repurchase Option (see Section 4), the Company
shall, upon the date of such termination (as reasonably fixed and determined by
the Company) have an irrevocable, exclusive option (the "Repurchase Option") for
a period of sixty (60) days from such date to repurchase up to that number of
shares which constitute the Unreleased Shares (as defined in Section 4) at the
original purchase price per share (the "Repurchase Price"). The Repurchase
Option shall be exercised by the Company by delivering written notice to the
Purchaser or the Purchaser's executor (with a copy to the Escrow Holder) AND, at
the Company's option, (i) by delivering to the Purchaser or the Purchaser's
executor a check in the amount of the aggregate Repurchase Price, or (ii) by
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals the aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price, the Company shall become the legal and beneficial owner of the
Shares being repurchased and all 




<PAGE>   41




rights and interests therein or relating thereto, and the Company shall have the
right to retain and transfer to its own name the number of Shares being
repurchased by the Company.

            (b)   Whenever the Company shall have the right to repurchase Shares
hereunder, the Company may designate and assign one or more employees, officers,
directors or shareholders of the Company or other persons or organizations to
exercise all or a part of the Company's purchase rights under this Agreement and
purchase all or a part of such Shares. If the Fair Market Value of the Shares to
be repurchased on the date of such designation or assignment (the "Repurchase
FMV") exceeds the aggregate Repurchase Price of such Shares, then each such
designee or assignee shall pay the Company cash equal to the difference between
the Repurchase FMV and the aggregate Repurchase Price of such Shares.

      4.    Release of Shares From Repurchase Option.

            (a)   _______________________ percent (______%) of the Shares shall
be released from the Company's Repurchase Option one year after the Date of
Grant and __________________ percent (______%) of the Shares at the end of each
month thereafter, provided that the Purchaser does not cease to be a Service
Provider prior to the date of any such release.

            (b)   Any of the Shares that have not yet been released from the
Repurchase Option are referred to herein as "Unreleased Shares."

            (c)   The Shares that have been released from the Repurchase Option
shall be delivered to the Purchaser at the Purchaser's request (see Section 6).

      5.    Restriction on Transfer. Except for the escrow described in Section
6 or the transfer of the Shares to the Company or its assignees contemplated by
this Agreement, none of the Shares or any beneficial interest therein shall be
transferred, encumbered or otherwise disposed of in any way until such Shares
are released from the Company's Repurchase Option in accordance with the
provisions of this Agreement, other than by will or the laws of descent and
distribution.

      6.    Escrow of Shares.

            (a)   To ensure the availability for delivery of the Purchaser's
Unreleased Shares upon repurchase by the Company pursuant to the Repurchase
Option, the Purchaser shall, upon execution of this Agreement, deliver and
deposit with an escrow holder designated by the Company (the "Escrow Holder")
the share certificates representing the Unreleased Shares, together with the
stock assignment duly endorsed in blank, attached hereto as Exhibit A-2. The
Unreleased Shares and stock assignment shall be held by the Escrow Holder,
pursuant to the Joint Escrow Instructions of the Company and Purchaser attached
hereto as Exhibit A-3, until such time as the Company's Repurchase Option
expires. As a further condition to the Company's obligations under this
Agreement, the Company may require the spouse of Purchaser, if any, to execute
and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-4.



                                      -2-


<PAGE>   42



            (b)   The Escrow Holder shall not be liable for any act it may do or
omit to do with respect to holding the Unreleased Shares in escrow while acting
in good faith and in the exercise of its judgment.

            (c)   If the Company or any assignee exercises the Repurchase Option
hereunder, the Escrow Holder, upon receipt of written notice of such exercise
from the proposed transferee, shall take all steps necessary to accomplish such
transfer.

            (d)   When the Repurchase Option has been exercised or expires
unexercised or a portion of the Shares has been released from the Repurchase
Option, upon request the Escrow Holder shall promptly cause a new certificate to
be issued for the released Shares and shall deliver the certificate to the
Company or the Purchaser, as the case may be.

            (e)   Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to the Shares while they are held in
escrow, including without limitation, the right to vote the Shares and to
receive any cash dividends declared thereon. If, from time to time during the
term of the Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Repurchase Option.

      7.    Legends. The share certificate evidencing the Shares, if any, issued
hereunder shall be endorsed with the following legend (in addition to any legend
required under applicable state securities laws):

      THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT
BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY.

      8.    Adjustment for Stock Split. All references to the number of Shares
and the purchase price of the Shares in this Agreement shall be appropriately
adjusted to reflect any stock split, stock dividend or other change in the
Shares which may be made by the Company after the date of this Agreement.

      9.    Tax Consequences. The Purchaser has reviewed with the Purchaser's
own tax advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. The Purchaser is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. The Purchaser understands that the Purchaser
(and not the Company) shall be responsible for the Purchaser's own tax liability
that may arise as a result of the transactions contemplated by this Agreement.
The Purchaser understands that Section 83 of the Internal Revenue Code of 1986,
as amended (the "Code"), taxes as ordinary 


                                      -3-


<PAGE>   43


income the difference between the purchase price for the Shares and the Fair
Market Value of the Shares as of the date any restrictions on the Shares lapse.
In this context, "restriction" includes the right of the Company to buy back the
Shares pursuant to the Repurchase Option. The Purchaser understands that the
Purchaser may elect to be taxed at the time the Shares are purchased rather than
when and as the Repurchase Option expires by filing an election under Section
83(b) of the Code with the IRS within 30 days from the date of purchase. The
form for making this election is attached as Exhibit A-5 hereto.

            THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

      10.   General Provisions.

            (a)   This Agreement shall be governed by the internal substantive
laws, but not the choice of law rules of California. This Agreement, subject to
the terms and conditions of the Plan and the Notice of Grant, represents the
entire agreement between the parties with respect to the purchase of the Shares
by the Purchaser. Subject to Section 16(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 Agreement, the terms and conditions of the Plan shall
prevail. Unless otherwise defined herein, the terms defined in the Plan shall
have the same defined meanings in this Agreement.

            (b)   Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and shall be deemed given when delivered
personally or deposited in the U.S. mail, First Class with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

            Any notice to the Escrow Holder shall be sent to the Company's
address with a copy to the other party hereto.

            (c)   The rights of the Company under this Agreement shall be
transferable to any one or more persons or entities, and all covenants and
agreements hereunder shall inure to the benefit of, and be enforceable by the
Company's successors and assigns. The rights and obligations of the Purchaser
under this Agreement may only be assigned with the prior written consent of the
Company.

            (d)   Either party's failure to enforce any provision of this
Agreement shall not in any way be construed as a waiver of any such provision,
nor prevent that party from thereafter enforcing any other provision of this
Agreement. The rights granted both parties hereunder are cumulative and shall
not constitute a waiver of either party's right to assert any other legal remedy
available to it.

            (e)   The Purchaser agrees upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

            (f)   PURCHASER ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES
PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED OR
PURCHASING SHARES HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT
THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE
SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED
ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT
ALL, AND SHALL NOT INTERFERE WITH PURCHASER'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE PURCHASER'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

      1.    In the event the Company and/or any assignee of the Company
(referred to collectively as the "Company") exercises the Company's Repurchase
Option set forth in the Agreement, the Company shall give to Purchaser and you a
written notice specifying the number of shares of stock to be purchased, the
purchase price, and the time for a closing hereunder at the principal office of

terms of said notice.

      2.    At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, against the simultaneous delivery to you of the purchase price (by

being purchased pursuant to the exercise of the Company's Repurchase Option.

      3.    Purchaser irrevocably authorizes the Company to deposit with you any

the Company or its assignees pursuant to exercise of the Company's Repurchase
Option.

further obligations hereunder.

      6.    Your duties hereunder may be altered, amended, modified or revoked

shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith,
and any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

      8.    You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law, and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree, you
shall not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

      9.    You shall not be liable in any respect on account of the identity,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

absence approved by the Company. Where the period of leave exceeds 90 days and

to the public as set forth in the final prospectus included within the

            (p)   "Subsidiary" shall mean a corporation, domestic or foreign, of
which not less than 50% of the voting shares are held by the Company or a
Subsidiary, whether or not such corporation now exists or is hereafter organized
or acquired by the Company or a Subsidiary.

            (q)   "Trading Day" shall mean a day on which national stock
exchanges and the Nasdaq System are open for trading.

      3.    Eligibility.

            (a)   Any Employee who shall be employed by the Company on a given
Enrollment Date shall be eligible to participate in the Plan.

            (b)   Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of the capital stock of the Company or of
any Subsidiary, or (ii) to the extent that his or her rights to purchase stock
under all employee stock purchase plans of the Company and its subsidiaries
accrues at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) worth of
stock (determined at the fair market value of the shares at the time such option
is granted) for each calendar year in which such option is outstanding at any
time.

      4.    Offering Periods. The Plan shall be implemented by consecutive,
overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after February 15 and August 15 each year, or on such other
date as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 20 hereof; provided, however, that the first Offering
Period under the Plan shall commence with the first Trading Day on or after the
date on which the Securities and Exchange Commission declares the Company's
Registration Statement effective and ending on the last Trading Day on or before
February 14. The Board shall have the power to change the duration of Offering
Periods (including the commencement dates thereof) with respect to future
offerings without shareholder approval if such change is announced at least five
(5) days prior to the scheduled beginning of the first Offering Period to be
affected thereafter.

      5.    Participation.

            (a)   An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

            (b)   Payroll deductions for a participant shall commence on the
first payroll following the Enrollment Date and shall end on the last payroll in
the Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

      6.    Payroll Deductions.

            (a)   At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period.

            (b)   All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

            (c)   A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

            (d)   Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to zero percent (0%) at any
time during a Purchase Period. Payroll deductions shall recommence at the rate
provided in such participant's subscription agreement at the beginning of the
first Purchase Period which is scheduled to end in the following calendar year,
unless terminated by the participant as provided in Section 10 hereof.

            (e)   At the time the option is exercised, in whole or in part, or
at the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,




<PAGE>   5



the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

      7.    Grant of Option. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than 3,000
shares of the Company's Common Stock (subject to any adjustment pursuant to
Section 19), and provided further that such purchase shall be subject to the
limitations set forth in Sections 3(b) and 12 hereof. The Board may, for future
Offering Periods, increase or decrease, in its absolute discretion, the maximum
number of shares of the Company's Common Stock an Employee may purchase during
each Purchase Period of such Offering Period. Exercise of the option shall occur
as provided in Section 8 hereof, unless the participant has withdrawn pursuant
to Section 10 hereof. The option shall expire on the last day of the Offering
Period.

      8.    Exercise of Option.

            (a)   Unless a participant withdraws from the Plan as provided in
Section 10 hereof, his or her option for the purchase of shares shall be
exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

            (b)   If the Board determines that, on a given Exercise Date, the
number of shares with respect to which options are to be exercised may exceed
(i) the number of shares of Common Stock that were available for sale under the
Plan on the Enrollment Date of the applicable Offering Period, or (ii) the
number of shares available for sale under the Plan on such Exercise Date, the
Board may in its sole discretion (x) provide that the Company shall make a pro
rata allocation of the shares of Common Stock available for purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Exercise Date, and continue all Offering Periods then in effect, or (y) provide
that the Company shall make a pro rata allocation of the shares available for
purchase on such Enrollment Date or 



<PAGE>   6



Exercise Date, as applicable, in as uniform a manner as shall be practicable and
as it shall determine in its sole discretion to be equitable among all
participants exercising options to purchase Common Stock on such Exercise Date,
and terminate any or all Offering Periods then in effect pursuant to Section 20
hereof. The Company may make pro rata allocation of the shares available on the
Enrollment Date of any applicable Offering Period pursuant to the preceding
sentence, notwithstanding any authorization of additional shares for issuance
under the Plan by the Company's shareholders subsequent to such Enrollment Date.

      9.    Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

      10.   Withdrawal.

            (a)   A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of Exhibit B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

            (b)   A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the
participant withdraws.

      11.   Termination of Employment.

            Upon a participant's ceasing to be an Employee, for any reason, he
or she shall be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 15 hereof, and such participant's option shall be automatically
terminated. The preceding sentence notwithstanding, a participant who receives
payment in lieu of notice of termination of employment shall be treated as
continuing to be an Employee for the participant's customary number of hours per
week of employment during the period in which the participant is subject to such
payment in lieu of notice.





<PAGE>   7



      12.   Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

      13.   Stock.

            (a)   Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be four hundred thousand (400,000) shares.

            (b)   The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

            (c)   Shares to be delivered to a participant under the Plan shall
be registered in the name of the participant or in the name of the participant
and his or her spouse.

      14.   Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

      15.   Designation of Beneficiary.

            (a)   A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to an
Exercise Date on which the option is exercised but prior to delivery to such
participant of such shares and cash. In addition, a participant may file a
written designation of a beneficiary who is to receive any cash from the
participant's account under the Plan in the event of such participant's death
prior to exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.

            (b)   Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.




<PAGE>   8



      16.   Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

      17.   Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

      18.   Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

      19.   Adjustments Upon Changes in Capitalization, Dissolution,
Liquidation, Merger or Asset Sale.

            (a)   Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the Reserves, the maximum number of shares each
participant may purchase each Purchase Period (pursuant to Section 7), as well
as the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised 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 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, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New 



<PAGE>   9



Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

            (c)   Merger or Asset Sale. In the event of a proposed sale of all
or substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option 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, any Purchase Periods
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date") and any Offering Periods then in progress shall end on the New
Exercise Date. The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

      20.   Amendment or Termination.

            (a)   The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in Section 19 hereof,
no such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its shareholders. Except as provided
in Section 19 and this Section 20 hereof, no amendment may make any change in
any option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any successor rule or provision or any other applicable law, regulation or stock
exchange rule), the Company shall obtain shareholder approval in such a manner
and to such a degree as required.

            (b)   Without shareholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

            (c)   In the event the Board determines that the ongoing operation
of the Plan may result in unfavorable financial accounting consequences, the
Board may, in its discretion and, to the 



<PAGE>   10



extent necessary or desirable, modify or amend the Plan to reduce or eliminate
such accounting consequence including, but not limited to:

                  (1) altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase
Price;

                  (2) shortening any Offering Period so that Offering Period
ends on a new Exercise Date, including an Offering Period underway at the time
of the Board action; and

                  (3) allocating shares.

                  Such modifications or amendments shall not require stockholder
approval or the consent of any Plan participants.

      21.   Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

      22.   Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

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

      23.   Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

      24.   Automatic Transfer to Low Price Offering Period. To the extent
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

                        1998 EMPLOYEE STOCK PURCHASE PLAN

                             SUBSCRIPTION AGREEMENT



_____ Original Application                          Enrollment Date: ___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)


1.    ___________ hereby elects to participate in the IDG Books Worldwide, Inc.
      1998 Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") and
      subscribes to purchase shares of the Company's Common Stock in accordance
      with this Subscription Agreement and the Employee Stock Purchase Plan.

2.    I hereby authorize payroll deductions from each paycheck in the amount of
      ____% of my Compensation on each payday (from 1 to 10%) during the
      Offering Period in accordance with the Employee Stock Purchase Plan.
      (Please note that no fractional percentages are permitted.)

3.    I understand that said payroll deductions shall be accumulated for the
      purchase of shares of Common Stock at the applicable Purchase Price
      determined in accordance with the Employee Stock Purchase Plan. I
      understand that if I do not withdraw from an Offering Period, any
      accumulated payroll deductions will be used to automatically exercise my
      option.

4.    I have received a copy of the complete Employee Stock Purchase Plan. I
      understand that my participation in the Employee Stock Purchase Plan is in
      all respects subject to the terms of the Plan. I understand that my
      ability to exercise the option under this Subscription Agreement is
      subject to shareholder approval of the Employee Stock Purchase Plan.

5.    Shares purchased for me under the Employee Stock Purchase Plan should be
      issued in the name(s) of (Employee or Employee and Spouse only):
      ___________ .

6.    I understand that if I dispose of any shares received by me pursuant to
      the Plan within 2 years after the Enrollment Date (the first day of the
      Offering Period during which I purchased such shares) or one year after
      the Exercise Date, I will be treated for federal income tax purposes as
      having received ordinary income at the time of such disposition in an
      amount equal to the 



<PAGE>   12



      excess of the fair market value of the shares at the time such shares were
      purchased by me over the price which I paid for the shares. I hereby agree
      to notify the Company in writing within 30 days after the date of any
      disposition of my shares and I will make adequate provision for Federal,
      state or other tax withholding obligations, if any, which arise upon the
      disposition of the Common Stock. The Company may, but will not be
      obligated to, withhold from my compensation the amount necessary to meet
      any applicable withholding obligation including any withholding necessary
      to make available to the Company any tax deductions or benefits
      attributable to sale or early disposition of Common Stock by me. If I
      dispose of such shares at any time after the expiration of the 2-year and
      1-year holding periods, I understand that I will be treated for federal
      income tax purposes as having received income only at the time of such
      disposition, and that such income will be taxed as ordinary income only to
      the extent of an amount equal to the lesser of (1) the excess of the fair
      market value of the shares at the time of such disposition over the
      purchase price which I paid for the shares, or (2) 15% of the fair market
      value of the shares on the first day of the Offering Period. The remainder
      of the gain, if any, recognized on such disposition will be taxed as
      capital gain.

7.    I hereby agree to be bound by the terms of the Employee Stock Purchase
      Plan. The effectiveness of this Subscription Agreement is dependent upon
      my eligibility to participate in the Employee Stock Purchase Plan.

8.    In the event of my death, I hereby designate the following as my
      beneficiary(ies) to receive all payments and shares due me under the
      Employee Stock Purchase Plan:

        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, 1998
(the "Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of an aggregate of 3,200,000 shares of Class
A Common Stock, par value $0.001 (the "Shares"), reserved for issuance pursuant
to the 1998 Stock Plan and the 1998 Employee Stock Purchase Plan (together, the
"Plans"). As your legal counsel, we have examined the proceedings taken and are
familiar with the proceedings proposed to be taken by you in connection with the
sale and issuance of the Shares under the Plans.

        It is our opinion that the Shares will be, when issued and sold in the
manner referred to in the Plans, 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 any subsequent amendment thereto.

                                        Very truly yours,

                                        /s/ Wilson Sonsini Goodrich & Rosati
