exercised in full, or is surrendered pursuant to an Option Exchange Program, the
unpurchased Shares which were subject thereto shall become available for future
grant or sale under the Plan (unless the Plan has terminated).  However, Shares
that have actually been issued under the Plan upon exercise of an Option, shall
not be returned to the Plan and shall not become available for future
distribution under the Plan.

     4.   Administration of the Plan.
          --------------------------

          (a)  Administrator.  The Plan shall be administered by the Board or a

Committee appointed by the Board, which Committee shall be constituted to comply
with Applicable Laws.

          (b)  Powers of the Administrator.  Subject to the provisions of the

Plan and, in the case of a Committee, the specific duties delegated by the Board

               (i) to determine the Fair Market Value;

                                      -3-
<PAGE>

          (ii)   to select the Service Providers to whom Options may from time
to time be granted hereunder;

          (iii)  to determine the number of Shares to be covered by each such
award granted hereunder;

          (iv)   to approve forms of agreement for use under the Plan;

          (v)    to determine the terms and conditions of any Option granted
hereunder.  Such terms and conditions include, but are not limited to, the
exercise price, the time or times when Options may be exercised (which may be
based on performance criteria), any vesting acceleration or waiver of forfeiture
restrictions, and any restriction or limitation regarding any Option or the
Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

          (vi)   to determine whether and under what circumstances an Option may
be settled in cash under subsection 9(e) instead of Common Stock;

          (vii)  to reduce the exercise price of any Option to the then current
Fair Market Value if the Fair Market Value of the Common Stock covered by such
Option has declined since the date the Option was granted;

          (viii) to initiate an Option Exchange Program;

          (ix)   to prescribe, amend and rescind rules and regulations relating
to the Plan, including rules and regulations relating to sub-plans established
for the purpose of qualifying for preferred tax treatment under foreign tax
laws;

          (x)    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 that number of Shares having a Fair Market Value equal to (or
lesser than) the minimum 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 Optionees 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; and

          (xi)   to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

     (c)  Effect of Administrator's Decision.  All decisions, determinations
          ----------------------------------
and interpretations of the Administrator shall be final and binding on all
Optionees.

  5. Eligibility.
     -----------

     (a)  Nonstatutory Stock Options and Stock Purchase Rights may be granted to
Service Providers. Incentive Stock Options may be granted only to Employees.

                                      -4-
<PAGE>

          (b)  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 5(b), 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.

          (c)  Neither the Plan nor any Option shall confer upon any Optionee
any right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall it interfere in any way with his or her
right or the Company's right to terminate such relationship at any time, with or
without cause.

     6.   Term of Plan.  The Plan shall become effective upon its adoption by
          ------------
the Board.  It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 14 of the Plan.

     7.   Term of Option.  The term of each Option shall be stated in the Option
          --------------
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof.  In the case of an Incentive Stock Option
granted to an Optionee who, at the time the 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 term of the Option shall
be five (5) years from the date of grant or such shorter term as may be provided
in the Option Agreement.

     8.   Option Exercise Price and Consideration.
          ---------------------------------------

          (a)  The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time of grant of such
Option, 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 exercise
price shall be no less than 110% of the Fair Market Value per Share on the date
of grant.

                    (B) granted to any other Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

               (ii) In the case of a Nonstatutory Stock Option

                    (A)  granted to a Service Provider who, at the time of grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of

                                      -5-
<PAGE>

stock of the Company or any Parent or Subsidiary, the exercise price shall be no
less than 110% of the Fair Market Value per Share on the date of grant.

                     (B)  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.

               (iii) Notwithstanding the foregoing, Options may be granted
with a per Share exercise price other than as required above pursuant to a
merger or other corporate transaction.

          (b)  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant).  Such consideration  may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
from a brokerage firm under a cashless exercise program approved the Company in
connection with the Plan, or (6) any combination of the foregoing methods of
payment.  In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

     9.   Exercise of Option.
          ------------------

          (a)  Procedure for Exercise; Rights as a Shareholder.  Any Option
               -----------------------------------------------
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.  Except in the case of Options granted to Officers,
Directors and Consultants, Options shall become exercisable at a rate of no less
than 20% per year over five (5) years from the date the Options are granted.
Unless the Administrator provides otherwise, vesting of Options granted
hereunder to Officers and Directors 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 Shares, 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 12 of the Plan.

                                      -6-
<PAGE>

     Exercise of an Option in any manner shall result in a decrease in 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, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) 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 the Option
as set forth in the Option Agreement).  In the absence of a specified time in
the Option Agreement, the Option shall remain exercisable for three (3) months
following the Optionee's termination.  If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan.  If, after termination,
the Optionee does not exercise his or her Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

          (c) Disability of Optionee.  If an Optionee ceases to be a Service
              ----------------------
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
(of at least six (6) months) to the extent the Option is vested on the date of
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement).  In the absence of a specified
time in the Option Agreement, the Option shall remain exercisable for twelve
(12) months following the Optionee's termination.  If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

          (d) Death of Optionee.  If an Optionee dies while a Service Provider,
              -----------------
the Option may be exercised within such period of time as is specified in the
Option Agreement (of at least six (6) months) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by bequest
or inheritance.  In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination.  If, at the time of death, the Optionee is not vested as to the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan.  If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

     10.  Non-Transferability of Options and Stock Purchase Rights.  The Options
          --------------------------------------------------------
and Stock Purchase Rights 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.

     11.  Adjustments Upon Changes in Capitalization, 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

                                      -7-
<PAGE>

the number of shares of Common Stock which have been authorized for issuance
under the Plan but as to which no Options have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option , as well
as the price per share of Common Stock covered by each such outstanding Option
shall be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock resulting from a stock split, reverse stock split,
stock dividend, combination or reclassification of the Common Stock, or any
other increase or decrease in the number of issued shares of Common Stock
effected without receipt of consideration by the Company. The 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 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 fifteen (15) 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 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 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 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, the Optionee shall fully vest in and
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable.  If an
Option becomes fully vested and exercisable in lieu of assumption or
substitution in the event of a merger or sale of assets, the Administrator shall
notify the Optionee in writing or electronically that the Option shall be fully
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period.  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 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 for
each

                                      -8-
<PAGE>

Share of Optioned Stock subject to the Option to be solely common stock of
the successor corporation or its Parent equal in fair market value to the per
share consideration received by holders of Common Stock in the merger or sale of
assets.

     12.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Service Provider to whom an
Option is so granted within a reasonable time after the date of such grant.

     13.  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.  No action authorized by section 13(a)
               --------------------
shall reduce the amount of any existing Option or change the terms and
conditions thereof without the Optionee's consent. No amendment of the Plan
shall, without approval of the shareholders of the Company, (a) increase the
total number of shares which may be issued under the Plan or increase the amount
or type of benefits that may be granted under the Plan; or (b) modify the
requirements as to eligibility under the Plan.

          (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.

     14.  Conditions Upon Issuance of Shares.
          ----------------------------------

          (a) Legal Compliance.  Shares shall not be issued pursuant to the
              ----------------
exercise of an Option  unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with 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, the Administrator may require the person exercising such Option to

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

<PAGE>

liability in respect of the failure to issue or sell such Shares as to which

          ---------

          1.  Grant of Option.  The Plan Administrator of the Company hereby
              ---------------
grants to the Optionee named in the Notice of Grant (the "Optionee"), an option
(the "Option") to purchase the number of Shares set forth in the Notice of
Grant, at the exercise price per Share set forth in the Notice of Grant (the
"Exercise Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to Section 13(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and 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 as defined in
Section 422 of the Code. Nevertheless, to the extent that it exceeds the
$100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

          2.  Exercise of Option.
              ------------------

              (a)  Right to Exercise.  This Option shall be exercisable during
                   -----------------
its term in accordance with the Vesting Schedule set out in the Notice of Grant
and with the applicable provisions of the Plan and this Option Agreement.

              (b)  Method of Exercise.  This Option shall be 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 with respect to which the Option is being exercised, and such other
representations and agreements as may be required by 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 the aggregate
Exercise Price.

     No Shares shall be issued pursuant to the exercise of an Option unless such
issuance and such exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Shares shall be considered transferred
to the Optionee on the date on which the Option is exercised with respect to
such Shares.

          3.   Optionee's Representations.  In the event the Shares have not
               --------------------------

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.
          ---------

          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. Optionee agrees to
execute and deliver such other agreements as may be reasonably requested by the
Company or the underwriter which are consistent with the foregoing or which are
necessary to give further effect thereto. 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

               (b)  consideration received by the Company from a brokerage firm
under a formal cashless exercise program approved by the Company in connection
with the Plan; or

               (c)  surrender of other Shares which, (i) in the case of Shares
acquired from the Company, either directly or indirectly, have been owned by the
Optionee for more than six (6) months on the date of surrender, and (ii) have a
Fair Market Value on the date of surrender equal to the aggregate Exercise Price
of the Exercised Shares.

          6.   Restrictions on Exercise.  This Option may not be exercised
               ------------------------
until such time as the Plan has been approved by the shareholders of the
Company, or if the issuance of such Shares upon such exercise or the method of
payment of consideration for such shares would constitute a violation of any
Applicable Law.

          7.   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
Optionee. The terms of the Plan and this Option Agreement shall be binding upon
the executors, administrators, heirs, successors and assigns of the Optionee.

                                      -3-
<PAGE>

          8.  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.

          9.  Tax Consequences.  Set forth below is a brief summary as of the
              ----------------
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. 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)  Exercise of NSO.  There may be a regular federal income tax
                   ---------------
liability the exercise of an 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 Shares on the date of exercise
over the Exercise Price. If Optionee is an Employee or a former Employee, the
Company will be required to withhold from Optionee's 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.

              (b)  Exercise of ISO.  If this Option qualifies as an ISO, there
                   ---------------
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

               (c)  Disposition of Shares.  In the case of an NSO, if Shares are
                    ---------------------
held 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. In the
case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (1) the Fair Market Value of the
Shares on the date of exercise, or (2) the sale price of the Shares. Any
additional gain will be taxed as capital gain, short-term or long-term depending
on the period that the ISO Shares were held.

               (d)  Notice of Disqualifying Disposition of ISO Shares.  If the
                    -------------------------------------------------
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

                                      -4-

          10.  Entire Agreement; Governing Law.  The Plan is incorporated
               -------------------------------
herein by reference. The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee. This agreement is governed by the internal substantive
laws but not the choice of law rules of California.

          11.  No Guarantee of Continued Service.  OPTIONEE ACKNOWLEDGES AND
               ---------------------------------
AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS
EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER). OPTIONEE 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 IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

     Optionee acknowledges receipt of a copy of the Plan and represents that he
or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof.  Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option.  Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option.
Optionee further agrees to notify the Company upon any change in the residence
address indicated below.

other transfer is effected in accordance with any applicable securities laws and

                                   ---------

                      INVESTMENT REPRESENTATION STATEMENT

     OPTIONEE:

     COMPANY:          DIGITAL BROADCAST NETWORK CORPORATION

     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, and Optionee will bear the economic risk of holding such
Securities for that indefinite period of time, unless and until the Securities
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, and with any other legend required under applicable
state securities laws.
<PAGE>

          (c)  Optionee is familiar with the provisions of Rule 144, promulgated
under the Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or indirectly from the issuer
thereof, in a non-public offering subject to the satisfaction of certain
conditions. If the Securities are resold in reliance on Rule 144, certain
conditions specified by Rule 144 must be satisfied, including (without
limitation): (1) the resale occurring 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; (2) 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, (3) the
availability of certain public information about the Company, (4) the amount of
Securities being sold during any three month period not exceeding the
limitations specified in Rule 144(e), and (5) the timely filing of a Form 144,
if applicable.

          (d)  Optionee further understands that in the event all of the
applicable requirements of Rule 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 Rule 144 is
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 Rule 144 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:

                                    _____________________________________

          II.  AGREEMENT
               ---------

               1.   Grant of Option. The Plan Administrator of the Company
                    ---------------
hereby grants to the Optionee named in the Notice of Grant (the "Optionee"), an
option (the "Option") to purchase the number of Shares set forth in the Notice
of Grant, at the exercise price per Share set forth in the Notice of Grant (the
"Exercise Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to Section 13(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and 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 as
defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds
the $100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

               2.   Exercise of Option.
                    ------------------

                    (a)  Right to Exercise.  This Option shall be exercisable
                         -----------------
during its term in accordance with the Vesting Schedule set out in the Notice of
Grant and with the applicable provisions of the Plan and this Option Agreement.

                    (b)  Method of Exercise. This Option shall be 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 with respect to which the Option is being exercised, and such
other representations and agreements as may be required by 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 the
aggregate Exercise Price.

          No Shares shall be issued pursuant to the exercise of an Option unless
such issuance and such exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Shares shall be considered transferred
to the Optionee on the date on which the Option is exercised with respect to
such Shares.

                                      -2-
<PAGE>

     3.   Optionee's Representations. In the event the Shares have not been
          --------------------------
registered under the Securities Act of 1933, as amended, 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. Optionee agrees to
execute and deliver such other agreements as may be reasonably requested by the
Company or the underwriter which are consistent with the foregoing or which are
necessary to give further effect thereto. 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 check;

          (b)  consideration received by the Company from a brokerage firm under
a formal cashless exercise program approved by the Company in connection with
the Plan; or

          (c)  surrender of other Shares which, (i) in the case of Shares
acquired from the Company, either directly or indirectly, have been owned by the
Optionee for more than six (6) months on the date of surrender, and (ii) have a
Fair Market Value on the date of surrender equal to the aggregate Exercise Price
of the Exercised Shares.

     6.   Restrictions on Exercise. This Option may not be exercised until such
          ------------------------
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any Applicable
Law.

     7.   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

                                      -3-
<PAGE>

the lifetime of Optionee only by Optionee. The terms of the Plan and this Option
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

     8.   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.

     9.   Tax  Consequences.  Set forth below is a brief summary as of the date
          -----------------
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. 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)       Exercise of NSO. There may be a regular federal income tax
                    ----------------
liability upon the exercise of an 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 Shares on the date of exercise
over the Exercise Price. If Optionee is an Employee or a former Employee, the
Company will be required to withhold from Optionee's 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 .

          (b)       Exercise of ISO. If this Option qualifies as an ISO, there
                    ---------------
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

          (c)       Disposition of Shares. In the case of an NSO, if Shares are
                    ---------------------
held 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. In the
case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (1) the Fair Market Value of the
Shares on the date of exercise, or (2) the sale price of the Shares. Any
additional gain will be taxed as capital gain, short-term or long-term depending
on the period that the ISO Shares were held.

          (d)       Notice of Disqualifying Disposition of ISO Shares. If the
                    -------------------------------------------------
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant,

                                      -4-
<PAGE>

or (2) the date one year after the date of exercise, the Optionee shall
immediately notify the Company in writing of such disposition. Optionee agrees
that Optionee may be subject to income tax withholding by the Company on the
compensation income recognized by the Optionee.

     10.  Entire Agreement; Governing Law. The Plan is incorporated
          -------------------------------
herein by reference. The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee. This agreement is governed by the internal substantive
laws but not the choice of law rules of California.

     11.  No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES
          ---------------------------------
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH
THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER). OPTIONEE 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 IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

     Optionee acknowledges receipt of a copy of the Plan and represents that he
or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option. Optionee
further agrees to notify the Company upon any change in the residence address
indicated below.

Optionee has received, read and understood the Plan and the Option Agreement and
agrees to abide by and be bound by their terms and conditions.

          4.   Rights as Shareholder. Until the issuance of the Shares (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 Shares shall be issued to
the Optionee as soon as practicable after the Option is exercised. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date of issuance except as provided in Section 11 of the Plan.

          5.   Company's Right of First Refusal. Before any Shares held by
               --------------------------------
Optionee 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
<PAGE>

("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).

          (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, but not 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 ("Purchase Price") for the
               --------------
Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. 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 Directors 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 120 days after the date of the Notice, that any such sale or
other transfer is effected in accordance with any applicable securities laws and
that 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, the transfer of any or all
of the Shares during the Optionee's lifetime or on the Optionee's death by will
or intestacy to the Optionee's immediate family or a trust for the benefit of
the Optionee's immediate family shall be exempt from the provisions of this
Section. "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 Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

                                      -2-
<PAGE>

          (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 of
the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended.

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

     7.   Restrictive Legends and Stop-Transfer Orders.
          --------------------------------------------

          (a)  Legends. Optionee 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:

                                    EXHIBIT B

                       INVESTMENT REPRESENTATION STATEMENT

         OPTIONEE:

         COMPANY:          DIGITAL BROADCAST NETWORK CORPORATION

         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, and Optionee will bear the economic risk of holding such
Securities for that indefinite period of time, unless and until the Securities
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.
<PAGE>

               (c)  Optionee is familiar with the provisions of Rule 144,
promulgated under the Securities Act, which, in substance, permits limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. If the Securities are resold in reliance on Rule 144,
certain conditions specified by Rule 144 must be satisfied, including (without
limitation): (1) the resale occurring 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; (2) 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, (3) the
availability of certain public information about the Company, (4) the amount of
Securities being sold during any three month period not exceeding the
limitations specified in Rule 144(e), and (5) the timely filing of a Form 144,
if applicable.

               (d)  Optionee further understands that in the event all of the
applicable requirements of Rule 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 Rule 144 is
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 Rule 144 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.

               (e)  Optionee understands that the certificate evidencing the
Securities will be imprinted with a legend that prohibits the transfer of the
Securities without the consent of the Commissioner of Corporations of
California. Optionee has read the applicable Commissioner's Rules with respect
to such restriction, a copy of which is attached.

                                        Signature of Optionee:

                                        ____________________________

         Title 10. Investment - Chapter 3. Commissioner of Corporations

         260.141.11: Restriction on Transfer.
         ----------  -----------------------

         (a) The issuer of any security upon which a restriction on transfer has
been imposed pursuant to Sections 260.102.6, 260.141.10 or 260.534 shall cause a

         (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
written consent of the Commissioner (until this condition is removed pursuant to

ancestors, descendants, or spouse; or to a transferee by a trustee or custodian
for the account of the transferee or the transferee's ancestors, descendants or
spouse;

             (5)      to holders of securities of the same class of the same
issuer;

             (6)      by way of gift or donation inter vivos or on death;

             (7)      by or through a broker-dealer licensed under the Code
(either acting as such or as a finder) to a resident of a foreign state,
territory or country who is neither domiciled in this state to the knowledge of
the broker-dealer, nor actually present in this state if the sale of such
securities is not in violation of any securities law of the foreign state,
territory or country concerned;

             (8)      to a broker-dealer licensed under the Code in a principal
transaction, or as an underwriter or member of an underwriting syndicate or
selling group;

              (9)     if the interest sold or transferred is a pledge or other
lien given by the purchaser to the seller upon a sale of the security for which
the Commissioner's written consent is obtained or under this rule not required;

              (10)    by way of a sale qualified under Sections 25111, 25112,
25113 or 25121 of the Code, of the securities to be transferred, provided that
no order under Section 25140 or subdivision (a) of Section 25143 is in effect
with respect to such qualification;

              (11)    by a corporation to a wholly owned subsidiary of such
corporation, or by a wholly owned subsidiary of a corporation to such
corporation;
<PAGE>

              (12)  by way of an exchange qualified under Section 25111,
25112 or 25113 of the Code, provided that no order under Section 25140 or
subdivision (a) of Section 25143 is in effect with respect to such
qualification;

              (13)  between residents of foreign states, territories or
countries who are neither domiciled nor actually present in this state;

              (14)  to the State Controller pursuant to the Unclaimed Property
Law or to the administrator of the unclaimed property law of another state; or

              (15)  by the State Controller pursuant to the Unclaimed Property
Law or by the administrator of the unclaimed property law of another state if,
in either such case, such person (i) discloses to potential purchasers at the
sale that transfer of the securities is restricted under this rule, (ii)
delivers to each purchaser a copy of this rule, and (iii) advises the
Commissioner of the name of each purchaser;

              (16)  by a trustee to a successor trustee when such transfer does
not involve a change in the beneficial ownership of the securities;

              (17)  by way of an offer and sale of outstanding securities in
an issuer transaction that is subject to the qualification requirement of
Section 25110 of the Code but exempt from that qualification requirement by
subdivision (f) of Section 25102; provided that any such transfer is on the
condition that any certificate evidencing the security issued to such transferee
shall contain the legend required by this section.

     (c)      The certificates representing all such securities subject to such
a restriction on transfer, whether upon initial issuance or upon any transfer
thereof, shall bear on their face a legend, prominently stamped or printed
thereon in capital letters of not less than 10-point size, reading as follows:

     "IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY, OR ANY
INTEREST THEREIN, OR TO RECEIVE ANY CONSIDERATION THEREFOR, WITHOUT THE PRIOR
WRITTEN CONSENT OF THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA,

     II.  AGREEMENT
          ---------

          1.   Grant of Option.  The Plan Administrator of the Company hereby
               ---------------
grants to the Optionee named in the Notice of Grant (the "Optionee"), an option
(the "Option") to purchase the number of Shares set forth in the Notice of
Grant, at the exercise price per Share set forth in the Notice of Grant (the
"Exercise Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference.  Subject to Section 13(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and 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 as defined in
Section 422 of the Code.  Nevertheless, to the extent that it exceeds the
$100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

          2.   Exercise of Option.
               ------------------

               (a) Right to Exercise.  This Option shall be exercisable during
                   -----------------
its term in accordance with the Vesting Schedule set out in the Notice of Grant
and with the applicable provisions of the Plan and this Option Agreement.

               (b) Method of Exercise.  This Option shall be 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 with respect to which the Option is being exercised, and such other
representations and agreements as may be required by 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 the aggregate
Exercise Price.

     No Shares shall be issued pursuant to the exercise of an Option unless such
issuance and such exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Shares shall be considered transferred
to the Optionee on the date on which the Option is exercised with respect to
such Shares.

                                      -2-
<PAGE>

          3.   Optionee's Representations. In the event the Shares have not been
               --------------------------
registered under the Securities Act of 1933, as amended, 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.
-

          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.  Optionee agrees to
execute and deliver such other agreements as may be reasonably requested by the
Company or the underwriter which are consistent with the foregoing or which are
necessary to give further effect thereto.  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 check;

               (b)  consideration received by the Company from a brokerage firm
under a formal cashless exercise program approved by the Company in connection
with the Plan; or

               (c)  surrender of other Shares which, (i) in the case of Shares
acquired from the Company, either directly or indirectly, have been owned by the
Optionee for more than six (6) months on the date of surrender, and (ii) have a
Fair Market Value on the date of surrender equal to the aggregate Exercise Price
of the Exercised Shares.

          6.   Restrictions on Exercise.  This Option may not be exercised until
               ------------------------
such time as the Plan has been approved by the shareholders of the Company, or
if the issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any Applicable
Law.

          7.   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
Optionee.  The terms of the Plan and this Option Agreement shall be binding upon
the executors, administrators, heirs, successors and assigns of the Optionee.

                                      -3-
<PAGE>

          8.   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.

          9.   Tax Consequences.  Set forth below is a brief summary as of the
               ----------------
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares.  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)  Exercise of NSO.  There may be a regular federal income tax
                    ---------------
liability upon the exercise of an 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 Shares on the date of exercise
over the Exercise Price.  If Optionee is an Employee or a former Employee, the
Company will be required to withhold from Optionee's 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.

               (b)  Exercise of ISO. If this Option qualifies as an ISO, there
                    ---------------
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

               (c)  Disposition of Shares. In the case of an NSO, if Shares are
                    ---------------------
held 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. In the
case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (1) the Fair Market Value of the
Shares on the date of exercise, or (2) the sale price of the Shares. Any
additional gain will be taxed as capital gain, short-term or long-term depending
on the period that the ISO Shares were held.

               (d)  Notice of Disqualifying Disposition of ISO Shares.  If the
                    -------------------------------------------------
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition.  Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

full purchase price of the Shares, as set forth in the Option Agreement, and any

          ---------------------------
received, read and understood the Plan and the Option Agreement and agrees to
abide by and be bound by their terms and conditions.

     4.   Rights as Shareholder. Until the issuance of the Shares (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 Shares shall be issued to the
Optionee as soon as practicable after the Option is exercised. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date of issuance except as provided in Section 11 of the Plan.

     5.   Company's Right of First Refusal. Before any Shares held by Optionee
          --------------------------------
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
<PAGE>

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).

          (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, but not 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 ("Purchase Price") for the
              --------------
Shares purchased by the Company or its assignee(s) under this Section shall be
the Offered Price.  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 Directors 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 120 days after the date of the Notice, that any such sale or
other transfer is effected in accordance with any applicable securities laws and
that 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, the transfer of any or all of the
Shares during the Optionee's lifetime or on the Optionee's death by will or
intestacy to the Optionee's immediate family or a trust for the benefit of the
Optionee's immediate family shall be exempt from the provisions of this Section.
"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 Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

                                      -2-
<PAGE>

          (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 of the
Company to the general public pursuant to a registration statement filed with
and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended.

     6.   Tax Consultation.  Optionee understands that Optionee may suffer

any tax advice.

                                   ---------

                      INVESTMENT REPRESENTATION STATEMENT

     OPTIONEE:

     COMPANY:       DIGITAL BROADCAST NETWORK CORPORATION

     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, and Optionee will bear the economic risk of holding such
Securities for that indefinite period of time, unless  and until the Securities
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, and with any other legend required under applicable
state securities laws.
<PAGE>

          (c) Optionee is familiar with the provisions of Rule 144, promulgated
under the Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or indirectly from the issuer
thereof, in a non-public offering subject to the satisfaction of certain
conditions. If the Securities are resold in reliance on Rule 144, certain
conditions specified by Rule 144 must be satisfied, including (without
limitation): (1) the resale occurring 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; (2) 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, (3) the
availability of certain public information about the Company, (4) the amount of
Securities being sold during any three month period not exceeding the
limitations specified in Rule 144(e), and (5) the timely filing of a Form 144,
if applicable.

          (d) Optionee further understands that in the event all of the
applicable requirements of Rule 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 Rule 144 is
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 Rule 144 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:

          4.  Administration of the Plan.
              --------------------------

                  -------------
or a Committee appointed by the Board, which Committee shall be constituted to
comply with Applicable Laws.

              (b) Powers of the Administrator.  Subject to the provisions of the
                  ---------------------------
Plan and, in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities, the
Administrator shall have the authority in its discretion:

                                      -3-
<PAGE>

                  (i)    to determine the Fair Market Value;

                  (ii)   to select the Service Providers to whom Options may
from time to time be granted hereunder;

                  (iii)  to determine the number of Shares to be covered by each
such award granted hereunder;

                  (iv)   to approve forms of agreement for use under the Plan;

                  (v)    to determine the terms and conditions of any Option
granted hereunder. Such terms and conditions include, but are not limited to,
the exercise price, the time or times when Options may be exercised (which may
be based on performance criteria), any vesting acceleration or waiver of
forfeiture restrictions, and any restriction or limitation regarding any Option
or the Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

                  (vi)   to determine whether and under what circumstances an
Option may be settled in cash under subsection 9(e) instead of Common Stock;

                  (vii)  to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option has declined since the date the Option was granted;

                  (viii) to initiate an Option Exchange Program;

                  (ix)   to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred treatment under foreign
laws;

                  (x)    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 that number of Shares having a Fair Market
Value equal to (or less than) the minimum 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
Optionees 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;
and

                  (xi)   to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

              (c) Effect of Administrator's Decision. All decisions,
                  ----------------------------------
determinations and interpretations of the Administrator shall be final and
binding on all Optionees.

                                      -4-
<PAGE>

          5.  Eligibility.
              -----------

              (a) Nonstatutory Stock Options may be granted to Service
Providers. Incentive Stock Options may be granted only to Employees. Service
Providers who are eligible to receive awards under this Plan shall not be
eligible to receive awards under the Company's 1999 Executive Stock Option Plan.

              (b) 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 5(b), 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.

              (c) Neither the Plan nor any Option shall confer upon any Optionee
any right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall it interfere in any way with his or her
right or the Company's right to terminate such relationship at any time, with or
without cause.

          6.  Term of Plan.  The Plan shall become effective upon its adoption
              ------------
by the Board.  It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 13 of the Plan.

          7.  Term of Option.  The term of each Option shall be stated in the
              --------------
Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. In the case of an Incentive Stock
Option granted to an Optionee who, at the time the 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 term of the Option shall
be five (5) years from the date of grant or such shorter term as may be provided
in the Option Agreement.

          8.  Option Exercise Price and Consideration.
              ---------------------------------------

              (a) The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

                  (i) In the case of an Incentive Stock Option

                      (A) granted to an Employee who, at the time of grant of
such Option, 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
exercise price shall be no less than 110% of the Fair Market Value per Share on
the date of grant.

                                      -5-
<PAGE>

                        (B) granted to any other Employee, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                  (ii)  In the case of a Nonstatutory Stock Option

                        (A) granted to a Service Provider who, at the time of
grant of such Option, 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 exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                        (B) 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.

                  (iii) Notwithstanding the foregoing, Options may be granted
with a per Share exercise price other than as required above pursuant to a
merger or other corporate transaction.

              (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant).  Such consideration  may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
from a brokerage firm under a cashless exercise program approved by the Company
in connection with the Plan, or (6) any combination of the foregoing methods of
payment.  In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

          9.  Exercise of Option.
              ------------------

              (a) Procedure for Exercise; Rights as a Shareholder.  Any Option
                  -----------------------------------------------
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.  Except in the case of Options granted to Officers,
Directors and Consultants, Options shall become exercisable at a rate of no less
than 20% per year over five (5) years from the date the Options are granted.
Unless the Administrator provides otherwise, vesting of Options granted
hereunder to Officers and Directors 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

                                      -6-
<PAGE>

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 Shares, 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 11 of the Plan.

              Exercise of an Option in any manner shall result in a decrease in
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, such Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement (of at
least thirty (30) days) 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 the Option
as set forth in the Option Agreement). In the absence of a specified time in the
Option Agreement, the Option shall remain exercisable for three (3) months
following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

              (c) Disability of Optionee.  If an Optionee ceases to be a Service
                  ----------------------
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
(of at least six (6) months) to the extent the Option is vested on the date of
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement).  In the absence of a specified
time in the Option Agreement, the Option shall remain exercisable for twelve
(12) months following the Optionee's termination.  If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

              (d) Death of Optionee. If an Optionee dies while a Service
                  -----------------
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (of at least six (6) months) to the extent that the
Option is vested on the date of death (but in no event later than the expiration
of the term of such Option as set forth in the Option Agreement) by the
Optionee's estate or by a person who acquires the right to exercise the Option
by bequest or inheritance. In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, at the time of death, the Optionee is not vested

                                      -7-
<PAGE>

as to the entire Option, the Shares covered by the unvested portion of the
Option shall immediately revert to the Plan. If the Option is not so exercised
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

              (e) Buyout Provisions. The Administrator may at any time offer to
                  -----------------
buy out for a payment in cash or Shares, an Option previously granted, based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

          10. Non-Transferability of Options.  The Options 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.

          11. Adjustments Upon Changes in Capitalization, 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 the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company.  The 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 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 fifteen (15) 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 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 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

                                      -8-
<PAGE>

Option 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, the Optionee shall fully vest in and have the right to exercise the
Option as to all of the Optioned Stock, including Shares as to which it would
not otherwise be vested or exercisable. If an Option becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee in writing or
electronically that the Option shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option shall terminate
upon the expiration of such period. For the purposes of this paragraph, the
Option shall be considered assumed if, following the merger or sale of assets,
the option or right confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Option immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); 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 for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

         12.  Time of Granting Options.  The date of grant of an Option shall,
              ------------------------
for all purposes, be the date on which the Administrator makes the determination
granting such Option or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Service Provider to whom an
Option is so granted within a reasonable time after the date of such grant.

         13.  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 Board 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.

                                      -9-
<PAGE>

          14. Conditions Upon Issuance of Shares.
              ----------------------------------

              (a) Legal Compliance.  Shares shall not be issued pursuant to the
                  ----------------
exercise of an Option  unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with 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, the Administrator 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.

          15. 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.

          16. Reservation of Shares.  The Company, during the term of this Plan,
              ---------------------
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

          17. Shareholder Approval. The Plan shall be subject to approval by the
              --------------------
shareholders of the Company within twelve (12) months after the date the Plan is
adopted.  Such shareholder approval shall be obtained in the degree and manner
required under Applicable Laws.

          18. Information to Optionees and Purchasers. 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 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.

     II.  AGREEMENT
          ---------

          1.   Grant of Option.  The Plan Administrator of the Company hereby
               ---------------
grants to the Optionee named in the Notice of Grant (the "Optionee"), an option
(the "Option") to purchase the number of Shares set forth in the Notice of
Grant, at the exercise price per Share set forth in the Notice of Grant (the
"Exercise Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference.  Subject to Section 13(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and 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 as defined in
Section 422 of the Code.  Nevertheless, to the extent that it exceeds the
$100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

          2.   Exercise of Option.
               ------------------

               (a) Right to Exercise. This Option shall be exercisable during
                   -----------------
its term in accordance with the Vesting Schedule set out in the Notice of Grant
and with the applicable provisions of the Plan and this Option Agreement.

               (b) Method of Exercise. This Option shall be 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 with respect to which the Option is being exercised, and such other
representations and agreements as may be required by 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 the aggregate
Exercise Price.

     No Shares shall be issued pursuant to the exercise of an Option unless such
issuance and such exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Shares shall be considered transferred
to the Optionee on the date on which the Option is exercised with respect to
such Shares.

          3.   Optionee's Representations. In the event the Shares have not been
               --------------------------
registered under the Securities Act of 1933, as amended, 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.
-

          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. Optionee agrees to
execute and deliver such other agreements as may be reasonably requested by the
Company or the underwriter which are consistent with the foregoing or which are
necessary to give further effect thereto.  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 check;

               (b)  consideration received by the Company from a brokerage firm
under a formal cashless exercise program approved by the Company in connection
with the Plan; or

               (c)  surrender of other Shares which, (i) in the case of Shares
acquired from the Company, either directly or indirectly, have been owned by the
Optionee for more than six (6) months on the date of surrender, and (ii) have a
Fair Market Value on the date of surrender equal to the aggregate Exercise Price
of the Exercised Shares.

          6.   Restrictions on Exercise.  This Option may not be exercised until
               ------------------------
such time as the Plan has been approved by the shareholders of the Company, or
if the issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any Applicable
Law.

          7.   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
Optionee.  The terms of the Plan and this Option Agreement shall be binding upon
the executors, administrators, heirs, successors and assigns of the Optionee.

                                      -3-
<PAGE>

          8.   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.

          9.   Tax Consequences.  Set forth below is a brief summary as of the
               ----------------
date of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares.  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)  Exercise of NSO.  There may be a regular federal income tax
                    ---------------
liability upon the exercise of an 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 Shares on the date of exercise
over the Exercise Price.  If Optionee is an Employee or a former Employee, the
Company will be required to withhold from Optionee's 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.

               (b)  Exercise of ISO. If this Option qualifies as an ISO, there
                    ---------------
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

               (c)  Disposition of Shares. In the case of an NSO, if Shares are
                    ---------------------
held 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. In the
case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (1) the Fair Market Value of the
Shares on the date of exercise, or (2) the sale price of the Shares. Any
additional gain will be taxed as capital gain, short-term or long-term depending
on the period that the ISO Shares were held.

               (d)  Notice of Disqualifying Disposition of ISO Shares.  If the
                    -------------------------------------------------
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition.  Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

                                      -4-
<PAGE>

          10.  Entire Agreement; Governing Law.  The Plan is incorporated herein
               -------------------------------
by reference.  The Plan and this Option Agreement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Optionee with respect to the subject matter hereof, and may not be modified
adversely to the Optionee's interest except by means of a writing signed by the
Company and Optionee.  This agreement is governed by the internal substantive
laws but not the choice of law rules of California.

          11.  No Guarantee of Continued Service.  OPTIONEE ACKNOWLEDGES AND
               ---------------------------------
AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS
EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT
THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER).  OPTIONEE 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 IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

     Optionee acknowledges receipt of a copy of the Plan and represents that he
or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof.  Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option.  Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option.
Optionee further agrees to notify the Company upon any change in the residence
address indicated below.

          ---------------------
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 Shares shall be issued to the
Optionee as soon as practicable after the Option is exercised. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date of issuance except as provided in Section 11 of the Plan.

     5.   Company's Right of First Refusal.  Before any Shares held by Optionee
          --------------------------------
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

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).

          (b) Exercise of Right of First Refusal.  At any time within thirty
              ----------------------------------

              --------------
Shares purchased by the Company or its assignee(s) under this Section shall be

the cash equivalent value of the non-cash consideration shall be determined by
the Board of Directors 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 120 days after the date of the Notice, that any such sale or
other transfer is effected in accordance with any applicable securities laws and
that 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.

intestacy to the Optionee's immediate family or a trust for the benefit of the
Optionee's immediate family shall be exempt from the provisions of this Section.

                                   ---------

                      INVESTMENT REPRESENTATION STATEMENT

     OPTIONEE:

     COMPANY:       DIGITAL BROADCAST NETWORK CORPORATION

     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, and Optionee
will bear the economic risk of holding such Securities for that indefinite
period of time, unless  and until the Securities 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, and any other legend required under applicable state securities laws.
<PAGE>

     (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 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:

                         _____________________________________
