Act, the Plan shall be administered in compliance with the requirements, if any,
of Rule 16b-3.

          3.3    Powers of the Board. In addition to any other powers set forth
in the Plan and subject to the provisions of the Plan, the Board shall have the

which, Options shall be granted and the number of shares of Stock to be subject
to each Option;

                                       4
<PAGE>   5

                 (b)  to designate Options as Incentive Stock Options or

                 (c)  to determine the Fair Market Value of shares of Stock or
other property;

                 (d)  to determine the terms, conditions and restrictions
applicable to each Option (which need not be identical) and any shares acquired
upon the exercise thereof, including, without limitation, (i) the exercise price
of the Option, (ii) the method of payment for shares purchased upon the exercise
of the Option, (iii) the method for satisfaction of any tax withholding
obligation arising in connection with the Option or such shares, including by
the withholding or delivery of shares of stock, (iv) the timing, terms and
conditions of the exercisability of the Option or the vesting of any shares
acquired upon the exercise thereof, (v) the time of the expiration of the

                 (e)  to approve one or more forms of Option Agreement;

                 (f)  to amend, modify, extend, cancel, renew, reprice or
otherwise adjust the exercise price of, or grant a new Option in substitution
for, any Option or to waive any restrictions or conditions applicable to any
Option or any shares acquired upon the exercise thereof;

                 (g)  to accelerate, continue, extend or defer the
exercisability of any Option or the vesting of any shares acquired upon the
exercise thereof, including with respect to the period following an Optionee's
termination of Service with the Participating Company Group;

                 (h)  to prescribe, amend or rescind rules, guidelines and
policies relating to the Plan, or to adopt supplements to, or alternative
versions of, the Plan, including, without limitation, as the Board deems
necessary or desirable to comply with the laws of, or to accommodate the tax
policy or custom of, foreign jurisdictions whose citizens may be granted
Options; and

                 (i)  to correct any defect, supply any omission or reconcile
any inconsistency in the Plan or any Option Agreement and to make all other
determinations and take such other actions with respect to the Plan or any
Option as the Board may deem advisable to the extent consistent with the Plan
and applicable law.

     4.   Shares Subject to Plan.
          ----------------------

          4.1    Maximum Number of Shares Issuable. Subject to adjustment as
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be Four Million (4,000,000) and shall consist
of authorized but unissued or

                                       5
<PAGE>   6

reacquired shares of Stock or any combination thereof. If an outstanding Option
for any reason expires or is terminated or canceled or if shares of Stock are
acquired upon the exercise of an Option subject to a Company repurchase option
and are repurchased by the Company at the Optionee's exercise price, the shares
of Stock allocable to the unexercised portion of such Option or such repurchased
shares of Stock shall again be available for issuance under the Plan.
Notwithstanding the foregoing, at any such time as the offer and sale of
securities pursuant to the Plan is subject to compliance with Section 260.140.45
of Title 10 of the California Code of Regulations ("Section 260.140.45"), the
total number of shares of Stock issuable upon the exercise of all outstanding
Options (together with options outstanding under any other stock option plan of
the Company) and the total number of shares provided for under any stock bonus
or similar plan of the Company shall not exceed thirty percent (30%) (or such
other higher percentage limitation as may be approved by the shareholders of the
Company pursuant to Section 260.140.45) of the then outstanding shares of the
Company as calculated in accordance with the conditions and exclusions of
Section 260.140.45.

          4.2    Adjustments for Changes in Capital Structure. In the event of
any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of the
Company, appropriate adjustments shall be made in the number and class of shares
subject to the Plan and to any outstanding Options and in the exercise price per
share of any outstanding Options. If a majority of the shares which are of the
same class as the shares that are subject to outstanding Options are exchanged
for, converted into, or otherwise become (whether or not pursuant to an
Ownership Change Event, as defined in Section 8.1) shares of another corporation
(the "New Shares"), the Board may unilaterally amend the outstanding Options to
provide that such Options are exercisable for New Shares. In the event of any
such amendment, the number of shares subject to, and the exercise price per
share of, the outstanding Options shall be adjusted in a fair and equitable
manner as determined by the Board, in its sole discretion. Notwithstanding the
foregoing, any fractional share resulting from an adjustment pursuant to this
Section 4.2 shall be rounded up or down to the nearest whole number, as
determined by the Board, and in no event may the exercise price of any Option be
decreased to an amount less than the par value, if any, of the stock subject to
the Option. The adjustments determined by the Board pursuant to this Section 4.2
shall be final, binding and conclusive.

     5.   Eligibility and Option Limitations.
          ----------------------------------

          5.1    Persons Eligible for Options. Options may be granted only to
Employees, Consultants, and Directors. For purposes of the foregoing sentence,
"Employees," "Consultants" and "Directors" shall include prospective Employees,
prospective Consultants and prospective Directors to whom Options are granted in
connection with written offers of an employment or other service relationship
with the Participating Company Group. Eligible persons may be granted more than
one (1) Option.

          5.2    Option Grant Restrictions. Any person who is not an Employee on
the effective date of the grant of an Option to such person may be granted only
a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective
Employee upon the condition that

                                       6
<PAGE>   7

such person become an Employee shall be deemed granted effective on the date
such person commences Service with a Participating Company, with an exercise
price determined as of such date in accordance with Section 6.1.

          5.3    Fair Market Value Limitation. To the extent that options
designated as Incentive Stock Options (granted under all stock option plans of
the Participating Company Group, including the Plan) become exercisable by an
Optionee for the first time during any calendar year for stock having a Fair
Market Value greater than One Hundred Thousand Dollars ($100,000), the portion
of such options which exceeds such amount shall be treated as Nonstatutory Stock
Options. For purposes of this Section 5.3, options designated as Incentive Stock
Options shall be taken into account in the order in which they were granted, and
the Fair Market Value of stock shall be determined as of the time the option
with respect to such stock is granted. If the Code is amended to provide for a
different limitation from that set forth in this Section 5.3, such different
limitation shall be deemed incorporated herein effective as of the date and with
respect to such Options as required or permitted by such amendment to the Code.
If an Option is treated as an Incentive Stock Option in part and as a
Nonstatutory Stock Option in part by reason of the limitation set forth in this
Section 5.3, the Optionee may designate which portion of such Option the
Optionee is exercising. In the absence of such designation, the Optionee shall
be deemed to have exercised the Incentive Stock Option portion of the Option
first. Separate certificates representing each such portion shall be issued upon
the exercise of the Option.

     6.   Terms and Conditions of Options.
          -------------------------------

          Options shall be evidenced by Option Agreements specifying the number
of shares of Stock covered thereby, in such form as the Board shall from time to
time establish. No Option or purported Option shall be a valid and binding
obligation of the Company unless evidenced by a fully executed Option Agreement.
Option Agreements may incorporate all or any of the terms of the Plan by
reference and shall comply with and be subject to the following terms and
conditions:

          6.1    Exercise Price. The exercise price for each Option shall be
established in the sole discretion of the Board; provided, however, that (a) the
exercise price per share for an Incentive Stock Option shall be not less than
the Fair Market Value of a share of Stock on the effective date of grant of the
Option, (b) the exercise price per share for a Nonstatutory Stock Option shall
be not less than eighty-five percent (85%) of the Fair Market Value of a share
of Stock on the effective date of grant of the Option, and (c) no Option granted
to a Ten Percent Owner Optionee shall have an exercise price per share less than
one hundred ten percent (110%) of the Fair Market Value of a share of Stock on
the effective date of grant of the Option. Notwithstanding the foregoing, an
Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be
granted with an exercise price lower than the minimum exercise price set forth
above if such Option is granted pursuant to an assumption or substitution for
another option in a manner qualifying under the provisions of Section 424(a) of
the Code.

          6.2    Exercise Period. Options shall be exercisable at such time or
times, or upon such event or events, and subject to such terms, conditions,
performance criteria, and

                                       7
<PAGE>   8

restrictions as shall be determined by the Board and set forth in the Option
Agreement evidencing such Option; provided, however, that (a) no Option shall be
exercisable after the expiration of ten (10) years after the effective date of
grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent
Owner Optionee shall be exercisable after the expiration of five (5) years after
the effective date of grant of such Option, (c) no Option granted to a
prospective Employee, prospective Consultant or prospective Director may become
exercisable prior to the date on which such person commences Service with a
Participating Company, and (d) with the exception of an Option granted to an
officer, Director or Consultant, no Option shall become exercisable at a rate
less than twenty percent (20%) per year over a period of five (5) years from the
effective date of grant of such Option, subject to the Optionee's continued
Service. Subject to the foregoing, unless otherwise specified by the Board in
the grant of an Option, any Option granted hereunder shall have a term of ten
(10) years from the effective date of grant of the Option.

          6.3    Payment of Exercise Price.

                 (a)  Forms of Consideration Authorized. Except as otherwise
provided below, payment of the exercise price for the number of shares of Stock
being purchased pursuant to any Option shall be made (i) in cash, by check, or
cash equivalent, (ii) by tender to the Company, or attestation to the ownership,
of shares of Stock owned by the Optionee having a Fair Market Value (as
determined by the Company without regard to any restrictions on transferability
applicable to such stock by reason of federal or state securities laws or
agreements with an underwriter for the Company) not less than the exercise
price, (iii) by the assignment of the proceeds of a sale or loan with respect to
some or all of the shares being acquired upon the exercise of the Option
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System) (a "Cashless Exercise"), (iv) by the
Optionee's promissory note in a form approved by the Company, (v) by such other
consideration as may be approved by the Board from time to time to the extent
permitted by applicable law, or (vi) by any combination thereof. The Board may
at any time or from time to time, by adoption of or by amendment to the standard
forms of Option Agreement described in Section 7, or by other means, grant
Options which do not permit all of the foregoing forms of consideration to be
used in payment of the exercise price or which otherwise restrict one or more
forms of consideration.

                 (b)  Tender of Stock. Notwithstanding the foregoing, an Option
may not be exercised by tender to the Company, or attestation to the ownership,
of shares of Stock to the extent such tender, or attestation to the ownership,
of Stock would constitute a violation of the provisions of any law, regulation
or agreement restricting the redemption of the Company's stock. Unless otherwise
provided by the Board, an Option may not be exercised by tender to the Company,
or attestation to the ownership, of shares of Stock unless such shares either
have been owned by the Optionee for more than six (6) months or were not
acquired, directly or indirectly, from the Company.

                 (c)  Cashless Exercise. The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to establish,
decline to approve or

                                       8
<PAGE>   9

terminate any program or procedures for the exercise of Options by means of a
Cashless Exercise.

                 (d)  Payment by Promissory Note. No promissory note shall be
permitted if the exercise of an Option using a promissory note would be a
violation of any law. Any permitted promissory note shall be on such terms as
the Board shall determine at the time the Option is granted. The Board shall
have the authority to permit or require the Optionee to secure any promissory
note used to exercise an Option with the shares of Stock acquired upon the
exercise of the Option or with other collateral acceptable to the Company.
Unless otherwise provided by the Board, if the Company at any time is subject to
the regulations promulgated by the Board of Governors of the Federal Reserve
System or any other governmental entity affecting the extension of credit in
connection with the Company's securities, any promissory note shall comply with
such applicable regulations, and the Optionee shall pay the unpaid principal and
accrued interest, if any, to the extent necessary to comply with such applicable
regulations.

          6.4    Tax Withholding. The Company shall have the right, but not the
obligation, to deduct from the shares of Stock issuable upon the exercise of an
Option, or to accept from the Optionee the tender of, a number of whole shares
of Stock having a Fair Market Value, as determined by the Company, equal to all
or any part of the federal, state, local and foreign taxes, if any, required by
law to be withheld by the Participating Company Group with respect to such
Option or the shares acquired upon the exercise thereof. Alternatively or in
addition, in its sole discretion, the Company shall have the right to require
the Optionee, through payroll withholding, cash payment or otherwise, including
by means of a Cashless Exercise, to make adequate provision for any such tax
withholding obligations of the Participating Company Group arising in connection
with the Option or the shares acquired upon the exercise thereof. The Company
shall have no obligation to deliver shares of Stock or to release shares of
Stock from an escrow established pursuant to the Option Agreement until the
Participating Company Group's tax withholding obligations have been satisfied by
the Optionee.

          6.5    Repurchase Rights. Shares issued under the Plan may be subject
to a right of first refusal, one or more repurchase options, or other conditions
and restrictions as determined by the Board in its sole discretion at the time
the Option is granted. The Company shall have the right to assign at any time
any repurchase right it may have, whether or not such right is then exercisable,
to one or more persons as may be selected by the Company. Upon request by the
Company, each Optionee shall execute any agreement evidencing such transfer
restrictions prior to the receipt of shares of Stock hereunder and shall
promptly present to the Company any and all certificates representing shares of
Stock acquired hereunder for the placement on such certificates of appropriate
legends evidencing any such transfer restrictions.

          6.6    Effect of Termination of Service.

                 (a)  Option Exercisability. Subject to earlier termination of
the Option as otherwise provided herein, an Option shall be exercisable after an
Optionee's termination of Service as follows:

                                       9
<PAGE>   10

                      (i)   Disability. If the Optionee's Service with the
Participating Company Group is terminated because of the Disability of the
Optionee, the Option, to the extent unexercised and exercisable on the date on
which the Optionee's Service terminated, may be exercised by the Optionee (or
the Optionee's guardian or legal representative) at any time prior to the
expiration of six (6) months (or such longer period of time as determined by the
Board, in its sole discretion) after the date on which the Optionee's Service
terminated, but in any event no later than the date of expiration of the
Option's term as set forth in the Option Agreement evidencing such Option (the
"Option Expiration Date").

                      (ii)  Death. If the Optionee's Service with the
Participating Company Group is terminated because of the death of the Optionee,
the Option, to the extent unexercised and exercisable on the date on which the
Optionee's Service terminated, may be exercised by the Optionee's legal
representative or other person who acquired the right to exercise the Option by
reason of the Optionee's death at any time prior to the expiration of six (6)
months (or such longer period of time as determined by the Board, in its sole
discretion) after the date on which the Optionee's Service terminated, but in
any event no later than the Option Expiration Date. The Optionee's Service shall
be deemed to have terminated on account of death if the Optionee dies within
thirty (30) days after the Optionee's termination of Service.

                      (iii) Other Termination of Service. If the Optionee's
Service with the Participating Company Group terminates for any reason, except
Disability or death, the Option, to the extent unexercised and exercisable by
the Optionee on the date on which the Optionee's Service terminated, may be
exercised by the Optionee within thirty (30) days (or such longer period of time
as determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

                 (b)  Extension if Exercise Prevented by Law. Notwithstanding
the foregoing, if the exercise of an Option within the applicable time periods
set forth in Section 6.6(a) is prevented by the provisions of Section 11 below,
the Option shall remain exercisable until one (1) month after the date the
Optionee is notified by the Company that the Option is exercisable, but in any
event no later than the Option Expiration Date.

                 (c)  Extension if Optionee Subject to Section 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods set
forth in Section 6.6(a) of shares acquired upon the exercise of the Option would
subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option
shall remain exercisable until the earliest to occur of (i) the tenth (10th) day
following the date on which a sale of such shares by the Optionee would no
longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day
after the Optionee's termination of Service, or (iii) the Option Expiration
Date.

     7.   Standard Forms of Option Agreement.
          ----------------------------------

          7.1    Incentive Stock Options. Unless otherwise provided by the Board
at the time the Option is granted, an Option designated as an "Incentive Stock
Option" shall comply with and be subject to the terms and conditions set forth
in the form of Incentive Stock Option

                                       10
<PAGE>   11

Agreement adopted by the Board concurrently with its adoption of the Plan and as
amended from time to time.

          7.2    Nonstatutory Stock Options. Unless otherwise provided by the
Board at the time the Option is granted, an Option designated as a "Nonstatutory
Stock Option" shall comply with and be subject to the terms and conditions set
forth in the form of Nonstatutory Stock Option Agreement adopted by the Board
concurrently with its adoption of the Plan and as amended from time to time.

          7.3    Authority to Vary Terms. The Board shall have the authority
from time to time to vary the terms of any of the standard forms of Option
Agreement described in this Section 7 either in connection with the grant or
amendment of an individual Option or in connection with the authorization of a
new standard form or forms; provided, however, that the terms and conditions of
any such new, revised or amended standard form or forms of Option Agreement
shall be in accordance with the terms of the Plan.

     8.   Change in Control.
          -----------------

          8.1    Definitions.

                 (a)  An "Ownership Change Event" shall be deemed to have
occurred if any of the following occurs with respect to the Company:

                      (i)   the direct or indirect sale or exchange in a single
or series of related transactions by the shareholders of the Company of more
than fifty percent (50%) of the voting stock of the Company;

                      (ii)  a merger or consolidation in which the Company is a
party;

                      (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                      (iv)  a liquidation or dissolution of the Company.

                 (b)  A "Change in Control" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "Transaction")
wherein the shareholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "Transferee
Corporation(s)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the

                                       11
<PAGE>   12

case may be, either directly or through one or more subsidiary corporations. The
Board shall have the right to determine whether multiple sales or exchanges of
the voting stock of the Company or multiple Ownership Change Events are related,
and its determination shall be final, binding and conclusive.

          8.2    Effect of Change in Control on Options. In the event of a
Change in Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "Acquiring
Corporation"), may either assume the Company's rights and obligations under
outstanding Options or substitute for outstanding Options substantially
equivalent options for the Acquiring Corporation's stock. For purposes of this
Section 8.2, an Option shall be deemed assumed if, following the Change in
Control, the Option confers the right to purchase in accordance with its terms
and conditions, for each share of Stock subject to the Option immediately prior
to the Change in Control, the consideration (whether stock, cash or other
securities or property) to which a holder of a share of Stock on the effective
date of the Change in Control was entitled. Any Options which are neither
assumed or substituted for by the Acquiring Corporation in connection with the
Change in Control nor exercised as of the date of the Change in Control shall
terminate and cease to be outstanding effective as of the date of the Change in
Control. Notwithstanding the foregoing, shares acquired upon exercise of an
Option prior to the Change in Control and any consideration received pursuant to
the Change in Control with respect to such shares shall continue to be subject
to all applicable provisions of the Option Agreement evidencing such Option
except as otherwise provided in such Option Agreement. Furthermore,
notwithstanding the foregoing, if the corporation the stock of which is subject
to the outstanding Options immediately prior to an Ownership Change Event
described in Section 8.1(a)(i) constituting a Change in Control is the surviving
or continuing corporation and immediately after such Ownership Change Event less
than fifty percent (50%) of the total combined voting power of its voting stock
is held by another corporation or by other corporations that are members of an
affiliated group within the meaning of Section 1504(a) of the Code without
regard to the provisions of Section 1504(b) of the Code, the outstanding Options
shall not terminate unless the Board otherwise provides in its sole discretion.

     9.   Provision of Information.
          ------------------------

          At least annually, copies of the Company's balance sheet and income
statement for the just completed fiscal year shall be made available to each
Optionee and purchaser of shares of Stock upon the exercise of an Option.  The
Company shall not be required to provide such information to persons whose
duties in connection with the Company assure them access to equivalent
information.

     10.  Nontransferability of Options.
          -----------------------------

          During the lifetime of the Optionee, an Option shall be exercisable
only by the Optionee or the Optionee's guardian or legal representative.  No
Option shall be assignable or transferable by the Optionee, except by will or by
the laws of descent and distribution.

     11.  Compliance with Securities Law.
          ------------------------------

                                       12
<PAGE>   13

          The grant of Options and the issuance of shares of Stock upon exercise
of Options shall be subject to compliance with all applicable requirements of
federal, state and foreign law with respect to such securities. Options may not
be exercised if the issuance of shares of Stock upon exercise would constitute a
violation of any applicable federal, state or foreign securities laws or other
law or regulations or the requirements of any stock exchange or market system
upon which the Stock may then be listed. In addition, no Option may be exercised
unless (a) a registration statement under the Securities Act shall at the time
of exercise of the Option be in effect with respect to the shares issuable upon
exercise of the Option or (b) in the opinion of legal counsel to the Company,
the shares issuable upon exercise of the Option may be issued in accordance with
the terms of an applicable exemption from the registration requirements of the
Securities Act. The inability of the Company to obtain from any regulatory body
having jurisdiction the authority, if any, deemed by the Company's legal 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.
As a condition to the exercise of any Option, the Company may require the
Optionee to satisfy any qualifications that may be necessary or appropriate, to
evidence compliance with any applicable law or regulation and to make any
representation or warranty with respect thereto as may be requested by the
Company.

     12.  Indemnification.
          ---------------

          In addition to such other rights of indemnification as they may have
as members of the Board or officers or employees of the Participating Company
Group, members of the Board and any officers or employees of the Participating
Company Group to whom authority to act for the Board or the Company is delegated
shall be indemnified by the Company against all reasonable expenses, including
attorneys' fees, actually and necessarily incurred in connection with the
defense of any action, suit or proceeding, or in connection with any appeal
therein, to which they or any of them may be a party by reason of any action
taken or failure to act under or in connection with the Plan, or any right
granted hereunder, and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent legal counsel selected by
the Company) or paid by them in satisfaction of a judgment in any such action,
suit or proceeding, except in relation to matters as to which it shall be
adjudged in such action, suit or proceeding that such person is liable for gross
negligence, bad faith or intentional misconduct in duties; provided, however,
that within sixty (60) days after the institution of such action, suit or
proceeding, such person shall offer to the Company, in writing, the opportunity
at its own expense to handle and defend the same.

     13.  Termination or Amendment of Plan.
          --------------------------------

          The Board may terminate or amend the Plan at any time. However,
subject to changes in applicable law, regulations or rules that would permit
otherwise, without the approval of the Company's shareholders, there shall be
(a) no increase in the maximum aggregate number of shares of Stock that may be
issued under the Plan (except by operation of the provisions of Section 4.2),
(b) no change in the class of persons eligible to receive Incentive Stock
Options, and (c) no other amendment of the Plan that would require approval of
the Company's

                                       13
<PAGE>   14

shareholders under any applicable law, regulation or rule. In any event, no
termination or amendment of the Plan may adversely affect any then outstanding
Option or any unexercised portion thereof, without the consent of the Optionee,
unless such termination or amendment is required to enable an Option designated
as an Incentive Stock Option to qualify as an Incentive Stock Option or is
necessary to comply with any applicable law, regulation or rule.

     14.  Shareholder Approval.
          --------------------

          The Plan or any increase in the maximum number of shares of Stock
issuable thereunder as provided in Section 4.1 (the "Maximum Shares") shall be
approved by the shareholders of the Company within twelve (12) months of the
date of adoption thereof by the Board. Options granted prior to shareholder
approval of the Plan or in excess of the Maximum Shares previously approved by
the shareholders shall become exercisable no earlier than the date of
shareholder approval of the Plan or such increase in the Maximum Shares, as the
case may be.

     IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that
the foregoing Alier, Inc. 1997 Stock Option Plan was duly adopted by the Board
on November ____, 1997.

may be issued under the Plan shall be One Million One Hundred Twenty Thousand
(1,120,000) and shall consist of authorized but unissued or reacquired shares of

<PAGE>   6

are acquired upon the exercise of an Option subject to a Company repurchase
option and are repurchased by the Company at the Optionee's exercise price, the
shares of Stock allocable to the unexercised portion of such Option or such
repurchased shares of Stock shall again be available for issuance under the
Plan.

          4.2  Adjustments for Changes in Capital Structure. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number and class of shares subject
to the Plan and to any outstanding Options and in the exercise price per share
of any outstanding Options. If a majority of the shares which are of the same
class as the shares that are subject to outstanding Options are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership
Change Event, as defined in Section 8.1) shares of another corporation (the "New
Shares"), the Board may unilaterally amend the outstanding Options to provide
that such Options are exercisable for New Shares. In the event of any such
amendment, the number of shares subject to, and the exercise price per share of,
the outstanding Options shall be adjusted in a fair and equitable manner as
determined by the Board, in its sole discretion. Notwithstanding the foregoing,
any fractional share resulting from an adjustment pursuant to this Section 4.2
shall be rounded up or down to the nearest whole number, as determined by the
Board, and in no event may the exercise price of any Option be decreased to an
amount less than the par value, if any, of the stock subject to the Option. The
adjustments determined by the Board pursuant to this Section 4.2 shall be final,
binding and conclusive.

     5.   Eligibility and Option Limitations.
          ----------------------------------

          5.1  Persons Eligible for Options. Options may be granted only to
Employees, Consultants, and Directors. For purposes of the foregoing sentence,
"Employees," "Consultants" and "Directors" shall include prospective Employees,
prospective Consultants and prospective Directors to whom Options are granted in
connection with written offers of an employment or other service relationship
with the Participating Company Group. Eligible persons may be granted more than
one (1) Option.

          5.2  Option Grant Restrictions. Any person who is not an Employee on
the effective date of the grant of an Option to such person may be granted only
a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective
Employee upon the condition that such person become an Employee shall be deemed
granted effective on the date such person commences Service with a Participating
Company, with an exercise price determined as of such date in accordance with
Section 6.1.

          5.3  Fair Market Value Limitation. To the extent that options
designated as Incentive Stock Options (granted under all stock option plans of
the Participating Company Group, including the Plan) become exercisable by an
Optionee for the first time during any calendar year for stock having a Fair
Market Value greater than One Hundred Thousand Dollars ($100,000), the portion
of such options which exceeds such amount shall be treated as Nonstatutory Stock
Options. For purposes of this Section 5.3, options designated as Incentive
<PAGE>   7

Stock Options shall be taken into account in the order in which they were
granted, and the Fair Market Value of stock shall be determined as of the time
the option with respect to such stock is granted. If the Code is amended to
provide for a different limitation from that set forth in this Section 5.3, such
different limitation shall be deemed incorporated herein effective as of the
date and with respect to such Options as required or permitted by such amendment
to the Code. If an Option is treated as an Incentive Stock Option in part and as
a Nonstatutory Stock Option in part by reason of the limitation set forth in
this Section 5.3, the Optionee may designate which portion of such Option the
Optionee is exercising. In the absence of such designation, the Optionee shall
be deemed to have exercised the Incentive Stock Option portion of the Option
first. Separate certificates representing each such portion shall be issued upon
the exercise of the Option.

     6.   Terms and Conditions of Options.
          -------------------------------

          Options shall be evidenced by Option Agreements specifying the number
of shares of Stock covered thereby, in such form as the Board shall from time to
time establish. No Option or purported Option shall be a valid and binding
obligation of the Company unless evidenced by a fully executed Option Agreement.
Option Agreements may incorporate all or any of the terms of the Plan by
reference and shall comply with and be subject to the following terms and
conditions:

          6.1  Exercise Price. The exercise price for each Option shall be
established in the sole discretion of the Board; provided, however, that (a) the
exercise price per share for an Incentive Stock Option shall be not less than
the Fair Market Value of a share of Stock on the effective date of grant of the
Option, (b) the exercise price per share for a Nonstatutory Stock Option shall
be not less than eighty-five percent (85%) of the Fair Market Value of a share
of Stock on the effective date of grant of the Option, and (c) no Option granted
to a Ten Percent Owner Optionee shall have an exercise price per share less than
one hundred ten percent (110%) of the Fair Market Value of a share of Stock on
the effective date of grant of the Option. Notwithstanding the foregoing, an
Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be
granted with an exercise price lower than the minimum exercise price set forth
above if such Option is granted pursuant to an assumption or substitution for
another option in a manner qualifying under the provisions of Section 424(a) of
the Code.

          6.2  Exercise Period. Options shall be exercisable at such time or
times, or upon such event or events, and subject to such terms, conditions,
performance criteria, and restrictions as shall be determined by the Board and
set forth in the Option Agreement evidencing such Option; provided, however,
that (a) no Option shall be exercisable after the expiration of ten (10) years
after the effective date of grant of such Option, (b) no Incentive Stock Option
granted to a Ten Percent Owner Optionee shall be exercisable after the
expiration of five (5) years after the effective date of grant of such Option,
(c) no Option granted to a prospective Employee, prospective Consultant or
prospective Director may become exercisable prior to the date on which such
person commences Service with a Participating Company, and (d) with the
exception of an Option granted to an officer, Director or Consultant, no Option
shall become exercisable at a rate less than twenty percent (20%) per year over
a period of five (5) years from the effective date of grant of such Option,
subject to the Optionee's continued Service. Subject
<PAGE>   8

to the foregoing, unless otherwise specified by the Board in the grant of an
Option, any Option granted hereunder shall have a term of ten (10) years from
the effective date of grant of the Option.

          6.3  Payment of Exercise Price.

               (a)  Forms of Consideration Authorized. Except as otherwise
provided below, payment of the exercise price for the number of shares of Stock
being purchased pursuant to any Option shall be made (i) in cash, by check, or
cash equivalent, (ii) by tender to the Company, or attestation to the ownership,
of shares of Stock owned by the Optionee having a Fair Market Value (as
determined by the Company without regard to any restrictions on transferability
applicable to such stock by reason of federal or state securities laws or
agreements with an underwriter for the Company) not less than the exercise
price, (iii) by the assignment of the proceeds of a sale or loan with respect to
some or all of the shares being acquired upon the exercise of the Option
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System) (a "Cashless Exercise"), (iv) by the
Optionee's promissory note in a form approved by the Company, (v) by such other
consideration as may be approved by the Board from time to time to the extent
permitted by applicable law, or (vi) by any combination thereof. The Board may
at any time or from time to time, by adoption of or by amendment to the standard
forms of Option Agreement described in Section 7, or by other means, grant
Options which do not permit all of the foregoing forms of consideration to be
used in payment of the exercise price or which otherwise restrict one or more
forms of consideration.

               (b)  Tender of Stock. Notwithstanding the foregoing, an Option
may not be exercised by tender to the Company, or attestation to the ownership,
of shares of Stock to the extent such tender, or attestation to the ownership,
of Stock would constitute a violation of the provisions of any law, regulation
or agreement restricting the redemption of the Company's stock. Unless otherwise
provided by the Board, an Option may not be exercised by tender to the Company,
or attestation to the ownership, of shares of Stock unless such shares either
have been owned by the Optionee for more than six (6) months or were not
acquired, directly or indirectly, from the Company.

               (c)  Cashless Exercise. The Company reserves, at any and all
times, the right, in the Company's sole and absolute discretion, to establish,
decline to approve or terminate any program or procedures for the exercise of
Options by means of a Cashless Exercise.

               (d)  Payment by Promissory Note. No promissory note shall be
permitted if the exercise of an Option using a promissory note would be a
violation of any law. Any permitted promissory note shall be on such terms as
the Board shall determine at the time the Option is granted. The Board shall
have the authority to permit or require the Optionee to secure any promissory
note used to exercise an Option with the shares of Stock acquired upon the
exercise of the Option or with other collateral acceptable to the Company.
Unless otherwise provided by the Board, if the Company at any time is subject to
the regulations promulgated by
<PAGE>   9

the Board of Governors of the Federal Reserve System or any other governmental
entity affecting the extension of credit in connection with the Company's
securities, any promissory note shall comply with such applicable regulations,
and the Optionee shall pay the unpaid principal and accrued interest, if any, to
the extent necessary to comply with such applicable regulations.

          6.4  Tax Withholding. The Company shall have the right, but not the
obligation, to deduct from the shares of Stock issuable upon the exercise of an
Option, or to accept from the Optionee the tender of, a number of whole shares
of Stock having a Fair Market Value, as determined by the Company, equal to all
or any part of the federal, state, local and foreign taxes, if any, required by
law to be withheld by the Participating Company Group with respect to such
Option or the shares acquired upon the exercise thereof. Alternatively or in
addition, in its sole discretion, the Company shall have the right to require
the Optionee, through payroll withholding, cash payment or otherwise, including
by means of a Cashless Exercise, to make adequate provision for any such tax
withholding obligations of the Participating Company Group arising in connection
with the Option or the shares acquired upon the exercise thereof. The Company
shall have no obligation to deliver shares of Stock or to release shares of
Stock from an escrow established pursuant to the Option Agreement until the
Participating Company Group's tax withholding obligations have been satisfied by
the Optionee.

          6.5  Repurchase Rights. Shares issued under the Plan may be subject to
a right of first refusal, one or more repurchase options, or other conditions
and restrictions as determined by the Board in its sole discretion at the time
the Option is granted. The Company shall have the right to assign at any time
any repurchase right it may have, whether or not such right is then exercisable,
to one or more persons as may be selected by the Company. Upon request by the
Company, each Optionee shall execute any agreement evidencing such transfer
restrictions prior to the receipt of shares of Stock hereunder and shall
promptly present to the Company any and all certificates representing shares of
Stock acquired hereunder for the placement on such certificates of appropriate
legends evidencing any such transfer restrictions.

          6.6  Effect of Termination of Service.

               (a)  Option Exercisability. Subject to earlier termination of the
Option as otherwise provided herein, an Option shall be exercisable after an
Optionee's termination of Service as follows:

                    (i)  Disability. If the Optionee's Service with the
Participating Company Group is terminated because of the Disability of the
Optionee, the Option, to the extent unexercised and exercisable on the date on
which the Optionee's Service terminated, may be exercised by the Optionee (or
the Optionee's guardian or legal representative) at any time prior to the
expiration of six (6) months (or such longer period of time as determined by the
Board, in its sole discretion) after the date on which the Optionee's Service
terminated, but in any event no later than the date of expiration of the
Option's term as set forth in the Option Agreement evidencing such Option (the
"Option Expiration Date").
<PAGE>   10

                    (ii)  Death. If the Optionee's Service with the
Participating Company Group is terminated because of the death of the Optionee,
the Option, to the extent unexercised and exercisable on the date on which the
Optionee's Service terminated, may be exercised by the Optionee's legal
representative or other person who acquired the right to exercise the Option by
reason of the Optionee's death at any time prior to the expiration of six (6)
months (or such longer period of time as determined by the Board, in its sole
discretion) after the date on which the Optionee's Service terminated, but in
any event no later than the Option Expiration Date. The Optionee's Service shall
be deemed to have terminated on account of death if the Optionee dies within
thirty (30) days after the Optionee's termination of Service.

                    (iii) Other Termination of Service. If the Optionee's
Service with the Participating Company Group terminates for any reason, except
Disability or death, the Option, to the extent unexercised and exercisable by
the Optionee on the date on which the Optionee's Service terminated, may be
exercised by the Optionee within thirty (30) days (or such longer period of time
as determined by the Board, in its sole discretion) after the date on which the
Optionee's Service terminated, but in any event no later than the Option
Expiration Date.

               (b)  Extension if Exercise Prevented by Law. Notwithstanding the
foregoing, if the exercise of an Option within the applicable time periods set
forth in Section 6.6(a) is prevented by the provisions of Section 11 below, the
Option shall remain exercisable until one (1) month after the date the Optionee
is notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date.

               (c)  Extension if Optionee Subject to Section 16(b).
Notwithstanding the foregoing, if a sale within the applicable time periods set
forth in Section 6.6(a) of shares acquired upon the exercise of the Option would
subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option
shall remain exercisable until the earliest to occur of (i) the tenth (10th) day
following the date on which a sale of such shares by the Optionee would no
longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day
after the Optionee's termination of Service, or (iii) the Option Expiration
Date.

     7.   Standard Forms of Option Agreement.
          ----------------------------------

          The Board shall have the authority from time to time to approve
standard forms of Option Agreement; provided, however, that the terms and
conditions of any such form or forms of Option Agreement shall be in accordance
with the terms of the Plan.

     8.   Change in Control.
          -----------------

          8.1  Definitions.

               (a)  An "Ownership Change Event" shall be deemed to have occurred
if any of the following occurs with respect to the Company:
<PAGE>   11

                    (i)   the direct or indirect sale or exchange in a single or
series of related transactions by the shareholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                    (ii)  a merger or consolidation in which the Company is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)  a liquidation or dissolution of the Company.

               (b)  A "Change in Control" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "Transaction")
wherein the shareholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "Transferee
Corporation(s)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          8.2  Effect of Change in Control on Options. In the event of a Change
in Control, the surviving, continuing, successor, or purchasing corporation or
parent corporation thereof, as the case may be (the "Acquiring Corporation"),
may either assume the Company's rights and obligations under outstanding Options
or substitute for outstanding Options substantially equivalent options for the
Acquiring Corporation's stock. For purposes of this Section 8.2, an Option shall
be deemed assumed if, following the Change in Control, the Option confers the
right to purchase in accordance with its terms and conditions, for each share of
Stock subject to the Option immediately prior to the Change in Control, the
consideration (whether stock, cash or other securities or property) to which a
holder of a share of Stock on the effective date of the Change in Control was
entitled. Any Options which are neither assumed or substituted for by the
Acquiring Corporation in connection with the Change in Control nor exercised as
of the date of the Change in Control shall terminate and cease to be outstanding
effective as of the date of the Change in Control. Notwithstanding the
foregoing, shares acquired upon exercise of an Option prior to the Change in
Control and any consideration received pursuant to the Change in Control with
respect to such shares shall continue to be subject to all applicable provisions
of the Option Agreement evidencing such Option except as otherwise provided in
such Option Agreement. Furthermore, notwithstanding the foregoing, if the
corporation the stock of which is subject to the outstanding Options immediately
prior to an
<PAGE>   12

Ownership Change Event described in Section 8.1(a)(i) constituting a Change in
Control is the surviving or continuing corporation and immediately after such
Ownership Change Event less than fifty percent (50%) of the total combined
voting power of its voting stock is held by another corporation or by other
corporations that are members of an affiliated group within the meaning of
Section 1504(a) of the Code without regard to the provisions of Section 1504(b)
of the Code, the outstanding Options shall not terminate unless the Board
otherwise provides in its sole discretion.

     9.   Provision of Information.
          ------------------------

          At least annually, copies of the Company's balance sheet and income
statement for the just completed fiscal year shall be made available to each
Optionee and purchaser of shares of Stock upon the exercise of an Option. The
Company shall not be required to provide such information to persons whose
duties in connection with the Company assure them access to equivalent
information.

     10.  Nontransferability of Options.
          -----------------------------

          During the lifetime of the Optionee, an Option shall be exercisable
only by the Optionee or the Optionee's guardian or legal representative. No
Option shall be assignable or transferable by the Optionee, except by will or by
the laws of descent and distribution.

     11.  Compliance with Securities Law.
          ------------------------------

          The grant of Options and the issuance of shares of Stock upon exercise
of Options shall be subject to compliance with all applicable requirements of
federal, state and foreign law with respect to such securities. Options may not
be exercised if the issuance of shares of Stock upon exercise would constitute a
violation of any applicable federal, state or foreign securities laws or other
law or regulations or the requirements of any stock exchange or market system
upon which the Stock may then be listed. In addition, no Option may be exercised
unless (a) a registration statement under the Securities Act shall at the time
of exercise of the Option be in effect with respect to the shares issuable upon
exercise of the Option or (b) in the opinion of legal counsel to the Company,
the shares issuable upon exercise of the Option may be issued in accordance with
the terms of an applicable exemption from the registration requirements of the
Securities Act. The inability of the Company to obtain from any regulatory body
having jurisdiction the authority, if any, deemed by the Company's legal 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.
As a condition to the exercise of any Option, the Company may require the
Optionee to satisfy any qualifications that may be necessary or appropriate, to
evidence compliance with any applicable law or regulation and to make any
representation or warranty with respect thereto as may be requested by the
Company.

     12.  Indemnification.
          ---------------
<PAGE>   13

          In addition to such other rights of indemnification as they may have
as members of the Board or officers or employees of the Participating Company
Group, members of the Board and any officers or employees of the Participating
Company Group to whom authority to act for the Board or the Company is delegated
shall be indemnified by the Company against all reasonable expenses, including
attorneys' fees, actually and necessarily incurred in connection with the
defense of any action, suit or proceeding, or in connection with any appeal
therein, to which they or any of them may be a party by reason of any action
taken or failure to act under or in connection with the Plan, or any right
granted hereunder, and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent legal counsel selected by
the Company) or paid by them in satisfaction of a judgment in any such action,
suit or proceeding, except in relation to matters as to which it shall be
adjudged in such action, suit or proceeding that such person is liable for gross
negligence, bad faith or intentional misconduct in duties; provided, however,
that within sixty (60) days after the institution of such action, suit or
proceeding, such person shall offer to the Company, in writing, the opportunity
at its own expense to handle and defend the same.

     13.  Termination or Amendment of Plan.
          --------------------------------

          The Board may terminate or amend the Plan at any time. However,
subject to changes in applicable law, regulations or rules that would permit
otherwise, without the approval of the Company's shareholders, there shall be
(a) no increase in the maximum aggregate number of shares of Stock that may be
issued under the Plan (except by operation of the provisions of Section 4.2),
(b) no change in the class of persons eligible to receive Incentive Stock
Options, and (c) no other amendment of the Plan that would require approval of
the Company's shareholders under any applicable law, regulation or rule. In any
event, no termination or amendment of the Plan may adversely affect any then
outstanding Option or any unexercised portion thereof, without the consent of
the Optionee, unless such termination or amendment is required to enable an
Option designated as an Incentive Stock Option to qualify as an Incentive Stock
Option or is necessary to comply with any applicable law, regulation or rule.

     14.  Shareholder Approval.
          --------------------

          The Plan or any increase in the maximum number of shares of Stock
issuable thereunder as provided in Section 4.1 (the "Maximum Shares") shall be
approved by the shareholders of the Company within twelve (12) months of the
date of adoption thereof by the Board. Options granted prior to shareholder
approval of the Plan or in excess of the Maximum Shares previously approved by
the shareholders shall become exercisable no earlier than the date of
shareholder approval of the Plan or such increase in the Maximum Shares, as the
case may be.
<PAGE>   14

     IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that
the foregoing Alier, Inc. 1996 Stock Option Plan was duly adopted by the Board
on April 1, 1996.
